Objective To determine the clinical efficacy of probucol in patients with diabetic macular edema (DME) and elevated serum lipids after focal/grid laser photocoagulation. Methods A prospective randomized controlled study included 48 type 2 diabetic patients with DME and dyslipidemia which were randomly divided into three groups. For patients with bilateral disease only the more severe eye was included. All patients were subjected to strict metabolic and blood pressure control during enrollment. All cases received macular laser photocoagulation. Besides, sixteen patients in group A were treated with probucol, 16 members in group B with atorvastatin and 16 members in group C were not treated with any lipid-lowering therapy for about three months. The outcome measurements were status of macular edema and hard exudates, visual acuity, foveal thickness, serum lipids and urine 8-hydroxydeoxyguanosine (8-OHdG) during the three months. Results The study included 20 men and 28 women with noninsulin dependent diabetes mellitus who could achieve good metabolic and blood pressure control within three months of inclusion in the study. Thirteen of 16 patients in group A, twelve of 16 patients in group B and five of 16 patients in group C showed reduction in hard exudates. Regression of macular edema was seen in twelve patients in group A, 11 in group B and eight in group C (χ2=2.368,P＞0.05). The difference of foveal thickness in group A, B and C was statistically significant (t=4.929, 4.669; P=0.000). Nine patients in group A, eight in group B and six in group C showed improving of visual acuity (χ2=1.169,P＞0.05). Three months after treatment, triglycerides (TG) (t=7.954, 6.832; P＜0.05), total cholesterol (TC) (t=6.643, 5.368; P＜0.05) and low-density lipoprotein cholesterol (LDLC) (t=3.279, 3.835; P＜0.05) decreased in group A and group B but not in group C, and high-density lipoprotein cholesterol showed no significant difference in the three groups. 8-OHdG decreased gradually during the first and third month in group A and group B but not in group C. In the first month post treatment, 8-OHdG showed no difference between group A and group B. In the third month, the 8-OHdG was lower in group A than group B, and the difference was statistically significant (t=2.947,P＜0.05). ConclusionsIn type 2 diabetes patients with DME and dyslipidemia, oral probucol can reduce the severity of hard exudates and macular edema, improve the visual acuity, and inhibit the levels of TG, TC, LDLC and 5-OHdG. The effect of probucol was similar to atorvastatin. Probucol could be an adjunct treatment of those patients.
ObjectiveTo compare the impact of early enteral nutrition (EN) and parenteral nutrition (PN) on the postoperative efficacy of esophageal cancer through meta-analysis of relevant randomized controlled trial (RCT).MethodsPubMed, Medline, EMbase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP, China Biology Medicine disc (CBMdisc) were searched by computer from inception to April 2018 to identify potential RCT which assessed clinical efficacy between EN and PN for postoperative patients with esophageal cancer. According to the inclusion and exclusion criteria, two researchers independently screened and evaluated literature. Meta-analysis was performed by RevMan 5.3 software.ResultsA total of 30 RCT studies were selected, including 3 969 patients. Meta-analysis results showed that: there was a significant difference between EN and PN in postoperative anastomotic fistulas (I2=0%, OR=0.67, 95%CI 0.45-0.99, P=0.04), postoperative pulmonary infections (I2=0%, OR=0.42, 95%CI 0.32-0.55, P<0.000 1), postoperative albumin levels (I2=38%, MD=0.78, 95%CI 0.51-1.06, P<0.000 01),time of first anal exhaust after operation (I2=0%, MD=–23.16, 95%CI –25.16-21.16, P<0.000 01) and postoperative incision infection (I2=0%, RR=0.36, 95%CI 0.21-0.64, P=0.000 5).ConclusionCompared with PN, early EN can significantly reduce the incidence of major postoperative complications and shorten the time of first anal exhaust after surgery. In addition, EN is superior to PN in improving nutritional status, increasing weight and reducing costs and side effects.
Peripapillary intrachoroidal cavitation (PICC) is a common pathological change observed in high myopia. The exact pathogenesis of PICC is still unclear. Expansion and mechanical stretching of the peripapillary sclera, breakage and defect in the retina near the border of the myopic conus and communication between intrachoroidal cavity and the vitreous space may be important segments during the development of PICC. Color fundus photography shows a localized and well-circumscribed peripapillary lesion with yellow-orange colour, often accompanied by fundus changes, such as myopic conus excavation, optic disc tilting and inferotemporal retinal vein bending at the transition from the PICC to the myopic conus. However, the PICC lesion is not easy to be recognized in the fundus photography. Fluorescein angiography shows early hypofluorescence and later progressively staining in the lesion. Indocyanine green angiography shows hypofluorescence throughout the examination. Optical coherence tomography (OCT) is vital in diagnosing PICC. Hyporeflective cavities inside the choroid, sometimes communicating with the vitreous chamber, can be observed in OCT images. OCT angiography indicates lower vessel density or even absence of choriocapillary network inside or around PICC lesions.
ObjectiveTo explore the feasibility of decompression without gastric tube after minimally invasive esophageal cancer surgery.MethodsSeventy-two patients who underwent minimally invasive esophageal cancer resection at the Department of Thoracic Surgery, The Second Affiliated Hospital of Harbin Medical University from 2016 to 2018 were selected as a trial group including 68 males and 4 females with an average age of 58.5±7.9 years, who did not use gastric tube for gastrointestinal decompression after surgery. Seventy patients who underwent the same operation from 2013 to 2015 were selected as the control group, including 68 males and 2 females, with an average age of 59.1±6.9 years, who were indwelled with gastric tube for decompression after surgery. We observed and compared the intraoperative and postoperative indicators and complications of the two groups.ResultsThere were no significant differences between the two groups in operation time, intraoperative blood loss, postoperative level of serum albumin, postoperative nasal jejunal nutrition, whether to enter the ICU postoperatively, death within 30 days after surgery, anastomotic leakage, lung infection, vomiting, bloating or hoarseness (P>0.05). No gastroparesis occurred in either group. Compared with the control group, the recovery time of the bowel sounds and the first exhaust time after the indwelling in the trial group were significantly shorter, and the total hospitalization cost, the incidence of nausea, sore throat, cough, foreign body sensation and sputum difficulty were significantly lower (P<0.05).ConclusionIt is feasible to remove the gastric tube for gastrointestinal decompression after minimally invasive esophageal cancer surgery, which will not increase the incidence of postoperative complications, instead, accelerate the postoperative recovery of patients.
Objective To investigate the application of transverse fascia in inguinal hernia repair. Methods In this study, 617 patients underwent inguinal hernia repair between January 1990 and December 2005 in our hospital were included, which were divided into two groups according to different operative ways: transverse fascia method group (n=337) and Bassini method group (n=280). Then intraoperative results, postoperative complications, and rehabilitated results of patients in two groups were compared. Results Compared with Bassini method group, the patients in transverse fascia method group did not show significant difference in operative time and blood loss during operation (Pgt;0.05). The differences of severe postoperative pain, testicular swelling, the time of the body’s restore for normal activities, and recurrence rate of patients between two groups were significant (Plt;0.05), while the difference of hematoma of scrotum and infection of incisional wound (Pgt;0.05). Conclusion The strengthening of posterior wall by transverse fascia and reconstruction of inner ring is a simple and effective method for inguinal hernia repair.
Objective To evaluate the effect of intraoperative fluid infusion volume on postoperative pulmonary complications (PPCs) in patients after minimally invasive endoscopic esophageal carcinoma resection. Methods From June 2019 to August 2021, 486 patients undergoing elective minimally invasive endoscopic esophagectomy for esophageal cancer were retrospectively screened from the electronic medical record information management system and anesthesia surgery clinical information system of West China Hospital of Sichuan University. There were 381 males and 105 females, with a median age of 64.0 years. Taking the incidence of pulmonary complications within 7 days after operation as the primary outcome, the correlation between intraoperative fluid infusion volume and the occurrence of PPCs within 7 days was clearly analyzed by regression analysis. ResultsThe incidence of pulmonary complications within 7 days after surgery was 33.5% (163/486). Regression analysis showed that intraoperative fluid infusion volume was correlated with the occurrence of PPCs [adjusted OR=1.089, 95%CI (1.012, 1.172), P=0.023], especially pulmonary infection [adjusted OR=1.093, 95%CI (1.014, 1.178), P=0.020], and pleural effusion [adjusted OR=1.147, 95%CI (1.007, 1.306), P=0.039]. Pulmonary infection was significantly less in the low intraoperative fluid infusion group [<6.49 mL/(kg·h), n=115] compared with the high intraoperative fluid infusion group [≥6.49 mL/(kg·h), n=371] (18.3% vs. 34.5%, P=0.023). Intraoperative fluid infusion volume was positively associated with death within 30 days after surgery [adjusted OR=1.442, 95%CI (1.056, 1.968), P=0.021]. Conclusion Among patients undergoing elective minimally invasive endoscopic esophageal cancer resection, intraoperative fluid infusion volume is related with the occurrence of PPCs within 7 days after the surgery, especially pulmonary infection and pleural effusion, and may affect death within 30 days after the surgery.
ObjectiveTo analyze the risk factors for neurological complications after emergency surgery of acute type A aortic dissection.MethodsThe clinical data of 51 patients with acute Stanford type A aortic dissection who were admitted to Shanghai Delta Hospital from October 2018 to May 2019 were retrospectively analyzed. There were 37 males (72.5%) and 14 females (27.5%), aged 29-85 (55.1±12.3) years. The patients were divided into two groups, including a N1 group (n=12, patients with postoperative neurological insufficiency) and a N0 group (n=39, patients without postoperative neurological insufficiency). The clinical data of the two groups were compared and analyzed.ResultsThere were statistical differences in age (62.6±11.2 years vs. 51.7±11.4 years, P=0.003), preoperative D-dimer (21.7±9.2 µg/L vs.10.8±10.7 µg/L, P=0.001), tracheal intubation time (78.7±104.0 min vs. 19.6±31.8 min, P=0.003), ICU stay time (204.1±154.8 min vs. 110.8±139.9 min, P=0.037) and preoperative coagulation factor activity R (4.0±1.5 vs. 5.1±1.6, P=0.022). Preoperative coagulation factor activity R was the independent risk factor for neurological insufficiency after emergency (OR=2.013, 95%CI 1.008-4.021, P=0.047).ConclusionFor patients with pre-emergent acute aortic dissection who are older (over 62.6-64.5 years), with reduced coagulation factor R (less than 4.0), it is recommended to take more active brain protection measures to reduce the occurrence of postoperative neurological complications in patients with acute aortic dissection, and further improve the quality of life.
Objective To investigate the relationship between diabetic retinopathy (DR) and coronary atherosclerosis (CAS) in type 2 diabetes patients and other risk factors of DR. Methods A total of 118 patients of type 2 diabetes with DR (DR group), 120 patients of type 2 diabetes without DR matched in age and sex (non-DR group), and 86 normal controls (control group) were enrolled in this study. The body mass index (BMI), blood pressure (BP), fasting blood-glucose (FPG), glycosylated haemoglobin (HbA1C), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterin (LDL-C), creatinine, estimate glomerular filtration rate (eGFR) and urinary albumin excretion rate(UAER) in all the subjects were measured. Meanwhile, the incidence of CAS in the three groups was detected by 64slice multidetector computed tomography angiography (MDCTA). Assume concurrent DR as dependent variable, clinical indicators and laboratory parameters as independent variable, the risk factors were determined by Logistic regression analysis. In addition, CAS as dependent variable, DR as fixed factor, analysis of covariance was used to investigate the relationship between CAS and DR. Results The incidence of CAS in DR group was higher than that in nonDR group and control group, the differences were statistically significant (chi;2=26.9,35.5;P＜0.05). The results of Logistic regression analysis showed that systolic BP, BMI, CAS, myocardial infarction and UAER were key risk factors for DR ［odds ratio (OR)=1.02, 0.89, 4.50, 3.89, 1.34;P＜0.05］. There was a negative relationship between BMI and DR. The results of analysis of covariance showed that there was significant correlation between CAS and DR (OR=5.31, 95% confidence interval=2.62-10.60; P＜0.05). Conclusion CAS is independently associated with DR in type 2 diabetes patients. In addition, the other risk factors for DR include systolic BP, BMI, myocardial infarction and UAER.
Objective To evaluate the therapeutic effects of vitrectomy with internal limiting membrane (ILM) peeling on retinal detachment in eyes with high myopia. Methods The clinical data of 25 high myopia patients (25 eyes) with retinal detachment and macular hole were retrospectively analyzed. The patients were divided into two groups according to the treatment:13 patients in group A had undergone conventional vitrectomy;12 patients in group B had undergone vitrectomy and ILM peeling.All patients had been tamponaded by inert gas and kept in a facedown position for 7-15 days after the operation. The followup period was 6-18 months (average 10 months).LogMAR visual acuity, ocular fundus, B-scan ultrasonography and optical coherence tomography had been followed up.Results Retinal reattachment was found in 7 eyes (53.8%) in group A and 11 eyes in group B (91.7%), the difference was significant(chi;2=4.427, P=0.046).The macular hole closed in 6 eyes (46.2%) in group A, and 11 eyes (91.7%) in group B; the difference was significant between those two groups (chi;2=5.940，P=0.020). The postoperative visual acuity increased significantly in both groups(Z=-2.045,2.481;P=0.041,0.012), the difference of vision improvement was not significant between those two groups (MannWhitnay U＝51.5，P=0.16). Conclusions By completely releasing the macular traction and increasing retinal flexibility, vitrectomy with ILM peeling can significantly increase the rate of retinal reattachment and closure of macular hole in eyes with high myopia.
