Objective To evaluate the effect of early clinical interference strategies on preventing the conversion of acute pancreatitis to the severe form and aggravation of severe acute pancreatitis (SAP). Methods The patients with acute pancreatitis admitted to this hospital were divided into two therapeutic phases by different therapeutic methods from January 2001 to December 2008. Patients in the first phase (from January 2001 to December 2004) were treated by the routine management, and the second phase (from January 2005 to December 2008) by the routine management combined with early clinical interference strategies. Then, the ratio of conversion from acute pancreatitis to SAP and prognosis of SAP between two phases were compared. Results Compared with the first phase, the rate of aggravation of acute pancreatitis was significantly decreased in the second phase (4.48% vs. 21.18%), the average healing time of SAP, the incidences of systemic and local complications and the mortality of pancreatitis were reduced (P＜0.05). When early clinical interference strategies were performed, some adverse reaction and complications occurred in 35 cases, but without severe consequence. Conclusion Early clinical interference strategies may serve as a beneficial strategy on preventing the progression of mild acute pancreatitis to the severe form or halting the aggravation of acute pancreatitis.
The coronavirus disease 2019 (COVID-19) epidemic has a tremendous impact on the countries around the world since the outbreak in December 2019. From December 2022, with the loosening of domestic epidemic control policies, the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) rose significantly and reached to its epidemic peak in the majority of the cities in China, which further overwhelmed our medical care system. The cardiac surgery departments in China lack the experience in conducting work under the COVID-19 pandemic. In this paper, we summarize the main topics that might be faced during the pandemic by reviewing the previous related literatures, which included: the cardiac surgery volume trends, the impact of SARS-CoV-2 infection on the prognosis of cardiac surgery, the timing of cardiac surgery and the surgical strategy should be modified, and possible recommendations for the manager or governors during the pandemic, so as to outline a path forward for cardiac surgery for the near future.

Objective To explore the clinical value, latest research progress, and clinical controversy of total neoadjuvant therapy (TNT) in locally advanced rectal cancer (LARC). Method We searched and reviewed on the latest literatures about studies of the clinical research of TNT in LARC. Results TNT could make the tumor downstage rapidly and improve the patients’ treatment compliance. In terms of organ preservation rate, 3-year disease-free survival and pathological complete remission rate, TNT had advantages and was a especial potential treatment strategy compared with traditional methods. Conclusions TNT decreases local recurrence rate and improves the long-term survival. For LARC patients with strong desire for organ preservation, TNT is a good treatment choice and has the value of clinical promotion.
Objective To evaluate and summarize the relevant evidence of oxygenation strategies with tracheal intubation after extubation for adult in intensive care unit (ICU), and to provide evidence-based practice for the development of scientific and effective strategies tracheal intubation after extubation for ICU adult patients. Methods Evidence-based databases, related guideline websites, association websites and original databases were searched by computer for literature about oxygenation strategies with tracheal intubation after extubation for ICU adults patients was extracted. The retrieval time was from the establishment of the databases to May 2023. Two researchers trained in evidence-based practice evaluated the quality of the included literature and extracted evidence from the literature that met the quality evaluation criteria. Results A total of 18 articles were included, including 7 guidelines, 4 clinical decisions, 2 expert consensus, 4 systematic reviews and 1 randomized controlled trial. A total of 22 pieces of best evidence were formed, including 7 aspects of basic principles, evaluation, selection, parameter setting, withdrawal, effect evaluation and precautions. ConclusionThe medical staff should select the best evidence based on the actual clinical situation and the patient’s own needs, and adjust the oxygenation strategies to reduce the rate of tracheal intubation and improve the prognosis of patients.
Objective To explore the intervention effect on colorectal cancer operation by neo-adjuvant chemotherapy in multi-disciplinary team. Methods To analyze retrospectively the data of patients diagnosed definitely as colorectal cancer in the West China Hospital of Sichuan University from July 2007 to December 2007, and the planned and actual operative strategy were compared between MDT group and non-MDT group. Results According to the inclusion criteria, 251 colorectal cancer patients were included which had 183 rectal cancer and 68 colon cancer. The baseline between MDT group and non-MDT group was equal, and there was no difference of planned operative strategy between two groups. For patients planned undergoing standard ano-saving radical procedure, the ratio of actual procedure same to the planned and the ratio of radical procedure changed to expansive ano-saving radical procedure showed no significant differences between MDT group and non-MDT group (Pgt;0.05), whereas the difference of the ratio of radical procedure changed to local radical procedure between two groups was statistically significant (Plt;0.01). And the constituent ratio of actual procedure between two groups for patients which planned accepted non-ano-saving procedure didn’t have any significant difference (Pgt;0.05). For the cancer focus, the relief differences of complete remission and partial remission were statistically significant between two groups (P＜0.01), but the difference of the constituent ratio of T staging change was not statistically significant (Pgt;0.05). Conclusion The value of neo-adjuvant chemotherapy should not be limited to decrease the stage of cancer, and it is important to pay more attention to the high quality of combined therapy. Further research should be carried out to find the contribution of neo-adjuvant chemotherapy to mini-invasive surgery.
ObjectiveTo analyze the death causes of postoperative early-stage after orthotopic liver transplantation (OLT) in rats, and to provide appropriate treatment strategies. MethodsThree hundreds of rat OLT models were performed by modified Kamada two-cuff technique. Operation time of each stage during OLT and postoperative survival time of rats were recorded and analyzed. According to survival time, the rats were divide into 4 groups:intraoperative death group (rats died during operation), < 6 hours group, 6-24 hours group, and > 24 hours group. Then comparison of operation time of each stage during OLT in rats of 4 groups was performed, and reasons of death during 24 hours after OLT were analyzed. ResultsOf the 300 OLT models, 37 rats died during operation (12.33%), 51 rats died within 6 hours after operation (17.00%), 76 rats died during 6-24 hours after operation (25.33%), and 136 rats survived longer than 24 hours (45.34%). The most common death causes of < 6 hours group were as follows:lose too much blood during the operation (27.45%, 14/51), postoperative bleeding (27.45%, 14/51), and vascular embolization (15.69%, 8/51). However, the most common death causes of 6-24 hours group were as follows:angiostenosis (27.63%, 21/76), postoperative bleeding (21.05%, 16/76), and pulmonary edema (19.74%, 15/76). There were significant differences in the cold ischemia time and anhepatic phase among the 4 groups (P < 0.05). The cold ischemia time and anhepatic phase of intraoperative death group were longer than those of other 3 groups (P < 0.05), in addition, the cold ischemia time of > 24 hours group was shorter than those of other 3 groups (P < 0.05). ConclusionsThere are many reasons leading to the early death after OLT. The long time of anhepatic phase and the cold ischemia time, intraoperative and postoperative bleeding, thrombosis, angiostenosis, and pulmonary edema are key factors for the improvement of prognosis in rats after OLT operation. Improvements of the reasons above are helpful to improve the successful rate of modeling and quality of OLT rats.
ObjectiveTo analyze the related risk factors for catheter-associated urinary tract infection in the Intensive Care Unit (ICU), and make corresponding nursing countermeasures. MethodsBy target monitoring of catheter-associated urinary tract infection in 184 patients in the ICU from 2011 to 2012, infection risk factors were analyzed. The measures of nursing interventions had been taken since January 2012, and the effects before and after the intervention were contrasted and evaluated. ResultsBefore the intervention, 951 out of 1 229 patients in 2011 had indwelling catheter, and catheter-associated urinary tract infection occurred in 127 patients with an infection rate of 13.35%. After the intervention, 841 out of 1 437 in 2012 had indwelling catheter, and catheter-associated urinary tract infection occurred in 57 patients with an infection rate of 6.78%. ConclusionTaking effective intervention measures can effectively reduce the ICU catheter-associated urinary tract infection and it also ensures the safety of medical care.
Objective To investigate clinical features of accidental parathyroid adenoma (APTA) and to explore diagnosis and treatment strategies of APTA. Methods From February 2009 to December 2016, the patients who would receive the thyroid surgery and were accidentally found the parathyroid adenoma by preoperative examination in the Department of Thyroid & Parathyroid Surgery, West China Hospital of Sichuan University were enrolled in the research. The clinical characteristics, surgical procedure, results of postoperative follow-up were analyzed retrospectively, and which were compared between the patients with APTA and the other patients diagnosed as primary parathyroid adenoma or received thyroid surgery (1 : 4 chosen randomly) in the same period. Results From February 2009 to December 2016, the patients who treated with thyroid surgery and were diagnosed as the primary parathyroid adenoma in our center were 5 881 and 251 respectively. Twenty-six patients with APTA were found in this research. The incidence rate of APTA was 0.44% (26/5 881), accounted for 10.4% (26/251) of the primary parathyroid adenoma. The positive rates of the ultrasound and the parathyroid scintigraphy were 69.2% (18/26) and 72.7% (8/11), respectively. The abnormal rate of the bone mineral density examination was 85.7% (6/7). The preoperative PTH was (38.17±40.69) pmol/L (3.40–181.20 pmol/L), and the serum calcium was (2.73±0.27) mmol/L (2.22–3.23 mmol/L). The number of detected parathyroid adenoma was 29, which were 55.2% (16/29) in the right-lower, 6.9% (2/29) in the right-upper, 27.6% (8/29) in the left-lower, and 10.3% (3/29) in the left-upper location. The rate of single parathyroid adenoma was 88.5% (23/26) and the maximum diameter of parathyroid adenoma was (21.72±9.65) mm. There was 13 cases (44.8%) of the A1 type and 16 cases (55.2%) of the B1 type in these 29 parathyroid adenomas. The rates of the recurrence, postoperative transient hypoparathyroidism, and permanent hypoparathyroidism were 7.7% (2/26), 30.8% (8/26), and 3.8% (1/26), respectively. Additionally, the preoperative PTH and serum calcium levels of the patients with APTA were significantly lower as compared with the primary parathyroid adenoma (P<0.001,P<0.001), which were significantly higher as compared with those of the patients received thyroid surgery without APTA in the same period (P=0.001, P<0.001). Conclusions APTA is a specific type of asymptomatic primary hyperparathyroidism. Examinations for PTH and serum calcium levels before thyroid surgery are important for finding APTA. For the patients with APTA, it is safe and effective to carry out exploratory parathyroidectomy with thyroid surgery at the same time.
