ObjectiveTo evaluate the efficacy of myomectomy via transumbilical laparoendompic single-site surgery (TU-LESS) and traditional multiport laparoscopy.MethodsThe study was conducted at Chengdu Western Hospital from June 2019 to June 2020. Fifty patients underwent TU-LESS myomectomy (TU-LESS group), while another 50 patients underwent traditional multiport laparoscopic myomectmy (multiport laparoscopy group). The conditions of operation, extra analgetic usage, VAS grade, and patients’ satisfaction degree were compared between two groups.ResultsPatients in both groups had similar age, BMI, fibroma volume, operative time, expelling gas day, blood loss, complication rate, and hospitalized costs (P>0.05). Compared with traditional multiport laparoscopy, the TU-LESS group resulted in significantly shorter hospitalization day, lower VAS score of the 1st/3nd/7th days after surgery, less use of analgetic after surgery, and higher satisfaction degree.ConclusionsTU-LESS is safe and feasible for myomectomy, and it is associated with less pain, shorter hospitalization day, and higher satisfaction degree.
Objective To evaluate the safety and efficacy of total hip arthroplasty (THA) in patients with end stage renal disease (ESRD). Methods Between December 2009 and May 2016, 30 THAs were performed in 28 patients with dialysis-dependent renal failure (18 patients) or renal transplantation (10 patients). A retrospective case control study was carried out to compare these 28 ESRD patients (ESRD group) with a matched cohort of 28 nonrenal patients (control group). There was no significant difference in gender, age, hip side, American Society of Anesthesiology (ASA) classification, comorbidities, and preoperative Harris score and hemoglobin (Hb) level between 2 groups (P>0.05). The complications during hospitalization, Hb level changes, perioperative transfusion rate, hospital stay, and hospitalization costs in 2 groups were evaluated; and the creatinine changes of dialysis patients in ESRD group were evaluated. During the follow-up period, 90 days readmissions, periprosthetic infection, prosthesis loosening, hip Harris score, and deaths were recorded. Results There was no loss of follow-up. The mean postoperative follow-up of ESRD group was 3.4 years (range, 1.0-7.4 years) and control group was 3.5 years (range, 1.0-7.4 years). Differences in hospital stay and the drop of Hb was not significant between 2 groups (P>0.05). The hospitalization costs and perioperative transfusion rate were significantly higher in ESRD group than in control group (P<0.05). There was no significant difference in creatinine value of dialysis patients in ESRD group between pre- and post-operation (t=1.804, P=0.089). At last follow-up, the Harris score was significantly higher than preoperative score in both groups (P<0.05); however, there was no significant difference in Harris score between groups (t=1.278, P=0.207). In ESRD group, 5 patients presented complications, 1 patient was readmitted to hospital, and 2 patients died during the follow-up. In control group, 1 patient presented complications, and there was no 90 days readmission and no death. During the follow-up period, there was no loosening or revision in 2 groups and the prosthesis was in good position. Conclusion THA can improve joint function and life quality of ESRD patients, but the risks of operation, perioperative complications, transfusion rate, and cost are high. Correct perioperative evaluation and management can help ESRD patients safely go through the perioperative period.
ObjectiveTo investigate the effect of jejunostomy combined with Ivor-Lewis or McKeown operation on the treatment of middle and lower esophageal cancer.MethodsThe clinical data of 127 patients with middle and lower esophageal cancer admitted to our hospital from June 2018 to October 2019 were retrospectively analyzed, including 89 males and 38 females, aged 62.82±8.65 years. The patients were divided into an Ivor-Lewis group (IL group, 72 patients) and a McKeown group (MK group, 55 patients) according to surgical methods. Patients in the IL group received jejunostomy combined with Ivor-Lewis operation, and patients in the MK group received jejunostomy combined with McKeown operation. The operation time, postoperative bedside electrical impedance tomography (EIT) parameters, postoperative inflammatory factor levels, postoperative complications and rehabilitation of the two groups were compared.ResultsThe operation time (262.65±49.78 min vs. 303.04±60.13 min), postoperative eating time (10.54±2.22 d vs. 11.47±2.49 d) and postoperative hospital stay (14.78±2.47 d vs.15.72±2.36 d) in the IL group were significantly shorter than those in the MK group (P<0.05). The blood loss (156.13±52.43 mL vs. 158.87±48.47 mL) and the number of lymph node dissection (29.47±8.88 vs. 30.17±9.80) in the IL group were less than those in the MK group, but the differences were not statistically significant (P>0.05). The repeated measurement analysis of variance showed that the time point could significantly affect tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and IL-8 levels (Ftime point=520.543, 272.379, 147.688, all P<0.05), but the surgical methods and the interactive effect of time point and surgical methods did not affect the levels of TNF-α, IL-6 and IL-8 (P>0.05). Postoperative bedside EIT image parameters were statistically different on the postoperative 1 d, 3 d, 5 d and 7 d between the two groups (P<0.05). Compared with the MK group, the incidences of recurrent laryngeal nerve injury, arrhythmia, pulmonary infection and atelectasis, anastomotic leakage, gastric wall necrosis and stump fistula, secondary thoracotomy and abdominal hemostasis, and intestinal obstruction were lower, but the differences were not statistically different (P>0.05). The recurrence rate of patients in the IL group within 6 months was lower than that in the MK group, but the difference was not statistically significant (8.33% vs. 9.09%, P>0.05).ConclusionJejunostomy combined with Ivor-Lewis or McKeown surgery have equivalent effects on patients with middle and lower esophageal cancer.
Objective To compare two kinds of myofascial flap encapsulating adi pose-derived stromal cells (ADSCs) in adi pogenic efficacy in vivo, and to provide experimental basis for the efficient transplantation of free adi pose tissue. Methods ADSCs were isolated from the subcutaneous adipose tissue in the neck of 10 New Zealand rabbits (aged 3-4 months old, male and female, weighing 2.0-2.5 kg), and primary culture and subculture of ADSCs were conducted. When the cells at passage 3 covered 70%-80% of the bottom of the culture flask, BrdU (10 μg/mL) was appl ied to label the cells for 48 hours before performing immunofluorescence staining. Oil red O staining observation was conducted to thosecells 2 weeks after being induced towards adi pocyte, al izarin red staining observation was performed 3 weeks after being induced towards osteoblast, and alcian blue staining was conducted 2 weeks after being induced towards chondrocyte. Besides, after being induced towards adipocyte for 2 weeks, 1 × 107 ADSCs/piece at passage 3 labeled by BrdU was seeded into Col I (10 mm × 10 mm × 5 mm/piece) to prepare cell carrier complex. The experiment was divided into two groups: group A in which vascular pedicled dextral latissimus dorsi fascial flap was adopted to encapsulate the complex; group B in which dextral gluteus maximus fascial flap with no specific vessel pedicle was appl ied to encapsulate the complex. Rabbits in each group went through autogenous ADSCs transplant and self control. The implants were dislodged 8 weeks after operation, HE staining and immunohistochemistry staining were performed to testify cambium, the wet weight and micro vessel count of the cambium in each group were tested, immunofluorescence staining was performed to determine the origin of cambium and microvascular endothel ium. Results The nucleus of ADSCs positive for BrdU label ing showed green fluorescence under fluorescence microscope, with the positive label ing ratio of ADSCs above 90%. For ADSCs at passage 3, the formation of red l ipid droplets within cells was observed 2 weeks after being induced towards adipocyte, red calcium nodules were evident 3 weeks after being induced towards osteoblast, and highly congregated cell mass positive for alcian blue staining appeared 2 weeks after being induced towards chondrocyte. Eight weeks after operation, neogenetic blood vessel grew into scaffolds and no obvious fibreencapsulation was observed in group A, while few blood vessel grew into scaffolds in group B. The wet weight of cambium in group A and B was (0.149 5 ± 0.017 3) g and (0.095 3 ± 0.012 7) g, respectively, indicating there was a significant difference between two groups (P lt; 0.01). HE staining showed the formation of neogenetic adipose tissue and the growth of micrangium in the implant, and the degradation and absorption of scaffold. The micro vessel count of group A and B was 31.2 ± 4.5 and 19.3 ± 2.6, respectively, indicating there was a significant difference between two groups (P lt; 0.01). Eight weeks after operation, the immunofluorescence staining of cambium showed that the cell nucleus of regenerated adi pocytes and partial capillary endothel ium in groups A and B presented green fluorescence. Conclusion ADSCs encapsulated by vascular pedicled latissimus dorsi fascial flap and collagen protein scaffold complex has a higher adi pogenic efficacy in vivo than the gluteus maximus fascial flap with no specific vessel pedicle.
ObjectiveTo analyze the clinical efficacy of etofenamate gel in patients with chronic trauma of locomotion system. MethodsRandomized parallel-controlled trial was conducted. From September 2011 to March 2012, 120 patients who were diagnosed with chronic trauma of locomotion system were divided into two groups. One was etofenamate gel group (group A), and the other was diclofenac sodium cream group (group B). Treatment course was two weeks. ResultsAfter two weeks of therapy, the effective rate of etofenamate gel was 85.0%, and of diclofenac sodium cream was 83.3%. The difference between etofenamate gel and diclofenac sodium cream had no statistical significance. Two drugs had similar efficacy in treating chronic trauma of locomotion system. Two patients in the etofenamate gel group and three in the diclofenac sodium cream group had very slight adverse reactions. ConclusionEtofenamate gel is effective in patients with chronic trauma of locomotion system, and the efficacy is similar with diclofenac sodium cream. It is particularly suitable for patients with gastrointestinal diseases.
ObjectiveTo investigate the effect of fasttrack (FT) and traditional care (TC) on patients with rectal cancer underwent different surgical strategies in perioperative period. MethodsThe clinical data of 285 patients with rectal cancer from January 2009 to January 2010 in this hospital were retrospectively analyzed. These patients underwent high anterior resection (HAR) or lower/super lower anterior resection (LAR) under FT and TC were divided into four groups: FT+HAR (n=39), FT+LAR (n=17), TC+HAR (n=151), and TC+LAR (n=78), and intraoperative conditions and postoperative rehabilitation were analyzed. ResultsThe baselines characteristics of four groups were basically identical (Pgt;0.05). ①The operative time and blood loss of patients in four groups were not statistically significant (Pgt;0.05). ②Anastomotic leakage occurred in three cases, wound infection in 13 cases, and intestinal obstruction in four cases after operation, and the difference was not significant in four groups (Pgt;0.05). ③The time of first defecation and first flatus of four groups were not statistically significant (Pgt;0.05), but there were significant differences in the time with drainage tube, nasogastric tube, and catheter tube, the time of first intake and first ambulation, and length of stay among four groups (Plt;0.05). Compared with TC+HAR and TC+LAR group, the time with drainage tube, nasogastric tube, and catheter tube, and the time of first intake and first ambulation of patients were shorter in FT+HAR and FT+LAR group, and the length of stay of patients in FT+LAR group was shorter than that in TC+HAR group and TC+LAR group (Plt;0.05). ConclusionsFT can promote postoperative rehabilitation of rectal cancer patients underwent different surgical strategies, but which does not demonstrate the superiority of reducing postoperative complications.

Objective To investigate the safety and efficacy of different doses of tranexamic acid (TXA) in posterior cervical laminectomy with lateral mass screw fixation and bone graft fusion by a prospective clinical study. Methods The middle-aged and elderly patients with cervical spondylotic myelopathy, who were admitted between January 2020 and January 2022 and scheduled to undergo posterior cervical laminectomy with lateral mass screw fixation and bone graft fusion, were studied as the research subjects. Among them, 165 patients met the selection criteria and were included in the study. The patients were allocated into 3 groups (n=55) by random double-blind lottery. Groups A and B were given intravenous infusion of TXA at 30 minutes before operation according to the standards of 15 and 30 mg/kg, respectively; and group C was given normal saline in the same way. There was no significant difference in gender, age, body mass index, and preoperative D-dimer, hemoglobin (Hb), and hematocrit (HCT) between groups (P>0.05). The intraoperative bleeding, intraoperative blood transfusion, postoperative drainage volume, drainage days, and postoperative hospital stay were recorded. The Hb, HCT, and D-dimer were compared before operation and at 3 days after operation. Venous ultrasonography of the lower extremities was taken after operation to assess thrombosis; and the postoperative hematoma and epilepsy were also observed. Results All operations were successfully completed, and the incisions healed by first intention. The differences in intraoperative bleeding volume, postoperative drainage volume, drainage days, and postoperative hospital stay between groups were significant (P<0.05). The above indexes were significantly less in group B than in groups A and C. During operation, 14 patients in group A and 23 patients in group C were transfused, and no patient in group B had blood transfusions. Compared with groups A and C, the blood transfusion volume in group B significantly decreased (P<0.05), and the difference between groups A and C was not significant (P>0.05). There was no significant difference in the differences of D-dimer, Hb, and HCT before and after operation between groups (P>0.05). At 5 days after operation, the venous ultrasonography of the lower extremities showed that the 2 cases of intermuscular venous thrombosis occurred in groups A, B, and C, respectively. No hematoma or epilepsy occurred after operation. Conclusion The application of 15 and 30 mg/kg TXA in posterior cervical laminectomy with lateral mass screw fixation and bone graft fusion can reduce intraoperative bleeding and postoperative drainage volume, postoperative drainage days, and postoperative hospital stay. And application of 30 mg/kg TXA can reduce intraoperative blood transfusion, without increasing the risk of lower extremity venous thrombosis, hematoma, and epilepsy.
Objective To assess efficacy of a mouthwash containing 0.1% cetylpiridinium on gingivitis and plaque and its safety. Methods Multi-center randomized double-blind trial with positive control and split-mouth comparison was designed. Scaling on teeth of left side were conducted at do then on those of right side at D8. The cases rinsed five times a day in same way with assigned agents. Efficacy was measured using before-after differences of clinical and microbial variables. Re-examinations were scheduled at D4 and D8. Brushing was refrained between D0 and D4, resumed between D4 and D8. Results There were 144 patients with gingivitis included, 4 lost follow up. Data of 69 cases in test group and 71 in control group could be analyzed. Baseline data analysis showed that distributions of sex, age and values of clinical and microbial variables in both groups were well comparable. At D4 plaque accumulations of the scaled side in both groups were in same level, and Gingival index (GI), sulcus bleeding index (SBI) and VAS for halitosis were significantly reduced. At D8 the measurements of plaque index (PI), GI, SBI and VAS of halitosis decreased significantly more than those of D4. More than half of the suspected pathogenic strains were eliminated and log value of its CFU/ml decreased significantly but at same level in both groups. The balance of intra-oral bacterial flora was not disturbed. Seventeen cases in test group (24.6%) had minor and transient adverse reactions related to the mouthwash. Antimicrobial tests in vitro confirmed that the test agent could kill or inhibit growth of the pathogenic bacteria involving with oropharyngeal infection, gingivitis, periodontal diseases and caries. Conclusion The mouthwash containing cetylpiridinium could inhibit plaque, reduce severity of gingivitis and halitosis, with acceptable minor adverse reactions, similar to those of the marketed cetylpiridinum solution.
ObjectiveTo evaluate the safety and efficacy of microwave ablation (MWA) in the treatment of lung tumors.MethodsThe clinical data of 31 patients with lung neoplasms treated with MWA from January 2019 to August 2020 in a single center were retrospectively analyzed. There were 17 males and 14 females at an age of 63.4±10.4 years. The characteristics of the lesions, technical success rate, technical efficiency, local progression rate, adverse reactions and complications were recorded in detail.ResultsThere were 39 target lesions with an average diameter of 20.2±10.6 mm. A total of 36 MWA procedures were completed. The initial technical success rate was 84.6% (33/39), and the technical efficiency was 92.3% (36/39). The median postprocedure hospital stay was 2.0 (2.0, 3.0) d. A total of 12.9% (4/31) of the patients had local progression, and the local control rate was 87.1%. The main adverse reactions were pain (12/36, 33.3%), cough (6/36, 16.7%), post-ablation syndrome (6/36, 16.7%) and pleural effusion (3/36, 8.3%). The main complications were pneumothorax (11/36, 30.6%), hemorrhage (8/36, 22.2%), cavitation (2/36, 5.6%) and pulmonary infection (1/36, 2.8%). The median follow-up time was 13.0 (8.0, 18.0) months. No patient died during the follow-up.ConclusionMWA is safe and effective in the treatment of lung tumors with controllable complications. Successive researches with large sample, and medium and long-term follow-ups are needed to explore the significance of combined therapies.
