ObjectiveTo investigate the change of cellmediated immunity in gut mucosa after major hepatectomy and to study its relationship with the bacteria translocation.MethodsFortyeight Spraguedawley adult male rats were randomly allocated into two groups, the sham operation group and the operation group. Besides without the hepatectomy, the sham operation group has the same course with the operation group. Seventy percent hepatectomy rats are divided as postoperative 6 h group (n=6)，12 h group (n=6)，24 h group (n=6) and 72 h group (n=6). Sixhour, 12hour, 24hour and 72hour after operation specimens were taken from jejunoileum respectively. Immunohistochemical staining was performed on frozen sections and image pattern analysis was used. We also investigate the change of liver function. ResultsTwentyfour hours and 72 hours after 70% hepatectomy, there was a significant reduction in the number of CD3+，CD4+and CD8+ T lymphocytes in the mucosal lamina propria of the operation group compared with the sham operation group （Plt;0.05）. There was significant difference between these two groups in liver function change （Plt;0.05）.ConclusionThere is an altered pattern of intestinal mucosal T lymphocytes after major hepatectomy, then the local cellmediated immunity was depressed, which may be the cause of translocation of enteric bacteria.
ObjectiveTo investigate the protective effect of SadenosylLmethionine on liver regeneration and liver function in cirrhotic rats after hepatectomy. MethodsCirrhosis was successfully induced by injection of 40% CCl4.Then,partial hepatectomy (about 30%) was performed in all rats. Cirrhotic rats were divided into 3 groups,namely,cirrhotic group (normal saline 5 ml/d,for 15 postoperative days，n=20),treatment group 1 〔S adenosylLmethionine 10 mg/(kg·d),for 15 postoperative days,n=16〕 and treatment group 2 〔SadenosylL methionine 20 mg/(kg·d),15 postoperative days,n=16〕,and normal control group was also established. Animals were sacrificed at the 15th postoperative day and 30th postoperative day to take samples for detection of liver function (Alb,ALT,TB,TBA) and serum TNFα.Liver tissues were also observed under light microscope and electron microscope. ResultsIn two treatment groups,at the time point (15 postoperative days or 30 postoperative days),concentrations of ALT,TB,TBA,Alb and TNFα were decreased significantly as compared with cirrhotic group (P ＜0.01),and concentration of Alb was increased significantly (P＜0.01).In contrast, there were no obvious difference in the same time point of different dosetreatment groups (Pgt;0.05),but the decrease of ALT,TB,TBA,TNFα and the increase of Alb were more significant at the second time point (30th postoperative day) than the first time point (15th postoperative day) when treated with same dose (P＜0.01).At the same time,concentration between TNF α and ALT,TB,TBA showed a positive correlation (P＜0.01),and the concentration between TNFα and Alb showed a negative correlation (P＜0.01).In addition, the histopathology showed SadenosylLmethionine had effects of protecting liver function and enhancing liver regeneration. ConclusionThe study suggests that SadenosylL methionine has the efficacy of enhancing liver regeneration and improving liver function.
Objective To study the application of virtual reality bronchoscopy stimulation in novice trainees. Methods Four novice bronchoscopists entered the training programby using a VR bronchoscopy in the clinical skill center. After the program, the dexterity, speed, and accuracy of all the four doctors were tested using the virtual simulation models. Results were compared to four skilled physicians as control group who had performed at least 50 bronchoscopies. Before-training and after-training test scores were compared using paired t tests. For comparisons between after-training novice and skilled physician scores, unpaired twosample t tests were used. Results All of the four trainees finished the training program. The novices significantly improved their dexterity, speed and accuracy. The percentage of observed segments increased from ( 74. 0 ±5. 1) % to ( 89. 3 ±4. 0) % . The number of contacts with the bronchial wall decreased from 87. 5 ±13. 2 to 30. 5 ±9. 3, and total time spent shortened from ( 700. 8 ±56. 6) s to ( 607. 0 ±17. 8) s. There were no statistically significant differences between novice accuracy ( the percentage of observed segments) after training and skilled physician accuracy [ ( 89. 3 ±4. 0) % vs ( 91. 3 ±3. 0) % , P = 0. 456] . Conclusion Practice using a virtual bronchoscopy simulator help novice trainees to attain a level of skill at performing diagnostic bronchoscopy, and it might play an important role in the training of chest physicians.

Methods From May 2008 to May 2009, we classified 22 cases of fresh displaced proximal humeral fracture according to the Neer classification. All patients were older than 60 years. There were two cases of two-part fracture, 16 cases of three-part fracture and four cases of four-part fracture. The open reduction and internal fixation with PHILOS plate was performed with the anterior deltopectoral approach. Results The 22 patients were followed up for 12 to 18 months with a mean period of 14.6 months. According to Constant-Murley Shoulder Score measurement, eight cases were graded as excellent, 10 good, three fair, and one poor with a excellent and good rate of 81.4%. Conclusion The open reduction and internal fixation with Philos plate is effective in treating elder patients with proximal humeral fracture.
After the promulgation of the “Ten New Measures” for coronavirus disease 2019 (COVID-19) pandemic, the Nursing Department of West China Hospital of Sichuan University promptly analyzed the development and changes of the epidemic situation and the key and difficult points of nursing manpower emergency management, and constructed a “1+2+4+X” nursing manpower emergency management model for COVID-19 patients, including establishing a dedicated management team, assessing manpower needs, constructing a nursing manpower management model, on-site and online training, and dynamic monitoring and adjustment. From December 7th, 2022 to February 1st, 2023, the Nursing Department mobilized a total of 693 nurses, covering 4 temporary intensive care units and 30 temporary general wards. The hospital-wide qualification rate of airway humidification management for patients in temporary general wards was 94.9%, the qualification rate of artificial airway fixation was 97.9%, and the compliance of bed head elevation was 100.0%. The “1+2+4+X” nursing manpower emergency management model constructed is helpful for the reasonable scheduling of nursing manpower during the epidemic period and provides a reference for the emergency deployment of nursing manpower for the treatment of infectious disease epidemics in large medical institutions in the future.

ObjectiveTo evaluate the value of magnetic resonance cholangiopancreatography (MRCP) on prevention of the complications in laparoscopic cholecystectomy (LC). MethodsThe clinical data of 1 079 patients underwent LC from January 2006 to June 2010 in this hospital were retrospectively analyzed. According to the use of MRCP or not in the different period, the patients were divided into nonMRCP group (n=523) and MRCP group (n=556). The occurrence of bile duct injuries (BDI) and retained common duct stone (RCDS) were compared between two groups. ResultsConversion to open surgery was performed in 35 cases in nonMRCP group and in 41 cases in MRCP group. The intraoperative and postoperative BDI were found in five patients and RCDS were found in 27 patients in nonMRCP group, and those were not found in patients in MRCP group. The differences of BDI and RCDS of patients were significant between two groups (P=0.026 and P=0.000). In nonMRCP group, 23 of 55 patients were found common bile duct stones by intraoperative cholangiography. Common bile duct stones were found by intraoperative cholangiography other than preoperative MRCP in three patients in MRCP group, while another three patients did not find common bile duct stones by intraoperative cholangiography although preoperative MRCP suggested. By MRCP, double gallbladders were found in one patient, Mirizzi syndrome in eight patients, variant cystic duct in 34 patients, accessory hepatic duct in 28 patients, and complicating common bile duct stones in 27 patients in MRCP group, the diagnostic accuracy of those were 100%, 87.5%, 94.1%, 89.3% and 88.9%, respectively. ConclusionPreoperative MRCP is helpful to prevent BDI and RCDS for the patients with LC.
