Objective To summarize the experience of laparoscopic appendectomy(LA). Methods A retrospective analysis was made on clinical date of 368 cases of appendicitis treated with laparoscopic appendectomy in this hospital from March 1998 to March 2005.There were 35 cases of simple appendicitis,276 cases of suppurative appendicitis,39 cases of appendiceal perforation with peritonitis,and 18 cases of chronic appendicitis. Results The procedure was successfully accomplished in 363 cases,while conversions to open surgery were performed in 5 cases.The operative time was 22~55 min(mean,30.5 min),and the intraoperative blood loss was 2~10 ml.One case of abdominal residual infection and 1 case of adhesive ileus were cured with conservative treatment postoperatively.Pelvic abscess occurred in 1 case and was cured with a re-operation of laparoscopic abscess drainage. Conclusions Laparoscopic appendectomy is safe and effective in skilled hands.

An investigation was made on 555 ranking Chinese Athletes engaged in 26 different sports and events. The type and incidence of vertebral deformity were counted. The incidence of low back pain as a result of the deformity was also counted. The relationship between low back pain and deformity was analyzed and the result was compared with 657 athletes who came to our clinic for treatment. The results were as follows:1. The incidence of secondary injury and illness in athletes with vertebral deformity was high. The incidence of spondylolysis in athletes with vertebral deformity was still higher. Athletes with serious deformity were liable to injury of bone, while those with light deformity were likely to develop injury of soft tissue.2. The pain of those with the deformity was mainly caused by secondary injury and illness but in a few of them the pain was the result of the vertebral deformity itself.3. To prevent the pain of vertebral deformity, it is important to prevent the development of secondary inry and illness.

ObjectiveTo study the expression level of HER-2 gene in the same pathological stage gastric cancer,and discuss the feasibility of HER-2 gene being the prognostic indicator.MethodsThe expression of HER-2 in gastric cancer was detected by immunohistocehmical technique and analyzed in relation with the pathological stage and prognosis of the patients.ResultsThe total positive rate of HER-2 in gastric cancer was 33.64％ (37/110).In stage Ⅱ,the weakly and strongly positive rates of gastric cancer were 21.31％ ( 13/61 ) and 9.84％ (6/61).In stage Ⅲ,the weakly and strongly positive rates of gastric cancer were 20.41％ (10/49) and 16.33％ (8/49).In the same pathological stage,the survival rate of patients with negative HER-2 expression was higher than weakly positive ones.And the survival rate of patients with strongly positive HER-2 expression was the lowest.The difference had statistical significance (P ＜ 0.01).ConclusionThe prognosis of patients in the same stage was correlated with the expression level of HER-2,which can be used to evaluate the biological behavior and prognosis of gastric cancer.

Objective To evaluate the effect of neoadjuvant chemotherapy on advanced gastric cancer before laparoscopic radical gastrectomy.Methods 46 advanced gastric cancer cases in our hospital from January 2010 to January 2013 were included in experimental group who were given two courses of neoadjuvant chemotherapy with FOLFOX regimen prior to surgery,the responsives (38 cases) received two more courses of neoadjuvant chemotherapy before surgery,and those in whom the chemotherapy was judged as ineffective (8 cases),received radical gastrectomy 21 days later.As a control,36 diseasematched cases went on upfront surgery without neoadjuvant chemotherapy.All these 82 cases underwent successful laparoscopic gastrectomy.Results The overall effective rate of neoadjuvant chemotherapy was 59％.Before the operation,the differences of pathological staging between the two groups were significantly different; The difference in operation time,the intraoperative blood loss and harvested lymph node number between the experimental group and control group was not statistically different (P ＞ 0.05).The R0 resection rate in experimental group (63％) was higher than in the control group (36％),P ＜0.05.The recurrence rate and mortality rate in experimental group was lower than that in the control group,P ＜ 0.05.Conclusions In advanced gastric carcinoma preoperative neoadjuvant chemotherapy significantly improved the resection rate and reduced postoperative recurrence and mortality rate.

Objective To observe the cough-preventing and asthma-relieving effect of Shaonianhong Fanxing Anti-asthmatic Syrup(SFAS).Methods The cough-preventing effect was observed in the experiment of cough induced by ammonia in mice;the phlegm-removing effect was observed in the experiment of eliminating phlegm with phenol red in mice;and the and-asthmatic effect was observed in the experiments of histamine inducing asthma and isolated tracheal smooth muscles of cavies.Results SFAS Can prolong the coughing time induced by ammomia,enhance the excretion of sputum,extend the delitescence period of ohosphoric acid hismmine induced asthma and restrain the contraction of isolated tracheal smooth muscles.Conclusion SFAS has phlegm-removing,cough-preventing and anti-asthmatic effects.

Aim To evaluate the effects of Brucine of restraining transplanted tumor growth,prolonging their survival time and its toxicity on haematopoietic and immune systems as well as hepatic and renal function in mice transplanted with Hepatocarcinoma Heps cells.Methods ICR male mice of Hepatocarcinoma Heps tumor model(Heps mice)was made through Heps cells inoculation.Anti-tumor activity of Brucine was evaluated in terms of tumor inhibitory ratio and life elongational ratio of mice transplanted with Heps tumor.The toxicity of Brucine was measured the mice weight,immune organ weight,blood cell index(leukocyte,erythrocyte,platelet,and hemachrome protein),and hepatic function index(ALT,AST)as well as renal function index(BUN) of Heps mice.Results Brucine had significant restraining effect on the growth of Heps tumor in mice.Its inhibitory rate was 30.34%(1.61 mg?kg~(-1)),46.21%(3.23 mg?kg~(-1))and 42.07%(6.46 mg?kg~(-1))respectively,and 3.23 mg?kg~(-1)(1/20 LD_(50)) was the best dosage of Brucine for treating Heps tumor in vivo,while Brucine had no distinct effect of prolonging the life of Heps mice.Moreover,it enhanced the weight of body and thymus index as well as spleen index,and had no distinct influence on blood cell index as well as ALT,AST and BUN in Heps mice.Conclusion Brucine can inhibit the growth of transplanted Heps tumor,enhance the weight of immune organ index significantly,and has no toxicity on haematopoietic and immune systems as well as hepatic and renal function of mice transplanted with Heps tumor.It may be developed into a promising anticancer drug through further study

CONCLUSION: Sorbitol carrier aggradation method is better than freeze drying method.

Objective To study the safety and short-term clinical outcome of different body mass index (BMI) patients with rectal cancer undergoing laparoscopic total mesorectal excision (TME). Methods The clinical data of 179 rectal cancer patients who had underwent laparoscopic TME from November 2016 to November 2017 were retrospectively analyzed. The patients were divided into 3 groups according to the BMI:leanness group (BMI<18.5 kg/m2, 15 cases), normal group (BMI 18.5 to 22.9 kg/m2, 89 cases) and overweight/obesity group (BMI ≥23.0 kg/m2, 75 cases). The general clinical data and the operation-related situation were compared. Results The rate of preoperative complications in overweight/obesity group was significantly higher than that in leanness group and normal group: 45.33％(34/75) vs. 4/15 and 28.09％(25/89), the preoperative albumin level in leanness group was significantly lower than that in normal group and overweight/obesity group:(36.3 ± 2.8) g/L vs. (38.6 ± 3.2) and (39.1 ± 3.7) g/L, and there were statistical differences (P<0.05). The operation time and blood loss in overweight/obesity group were significantly higher than those in leanness group and normal group: (149.2 ± 32.9) min vs. (129.3 ± 28.7) and (133.5 ± 23.6) min, (135.5 ± 29.0) ml vs. (117.5 ± 22.6) and (122.5 ± 25.9) ml, and there were statistical differences (P<0.05). There were no statistical differences in sex, age, tumor location, tumor maximum diameter, depth of tumor invasion, lymph node metastases, surgical approach, circumferential margin, number of lymph node dissections, length of resected specimens, incidence of postoperative complications, surgical site infection, postoperative urinary retention, postoperative exhaust time and postoperative hospitalization among 3 groups (P>0.05). Conclusions The differences of BMI mean different complications and nutritional status of patients. Overweight and obesity can lead to difficult operation of laparoscopic TME, but do not affect the radical cure of operations and the safety of clinical outcomes.

OBJECTIVETo explore the influence of recombinant human growth hormone (rhGH) on the apoptosis and intestinal mucosal structure in severely scalded rats.

METHODSThirty male Wistar rats were randomly divided into three groups, i.e. control, scalding and rhGH groups. The rats in scalding and rhGH groups were inflicted with 25% TBSA III degree scalding on the back and immediately followed by intraperitoneal injection of dexamethasone (80 mg/kg). The scalded rats were administered with normal saline and rhGH (1.33 IU.kg(-1).d(-1)) since 2 postburn hours (PBHs), respectively in the last two groups. The changes of the apoptosis rate, the intestinal mucosal proliferative index (PI) and epithelial ultrastructure and the intestinal mucosal pathomorphology of the distal end of ileal mucosal tissue were observed on 30 and 96 PBHs.

RESULTSThe intestinal mucosa morphology and epithelia in scalding group were severely injured but were significantly ameliorated by rhGH to near those in control group. The PI in rhGH and scalding groups at 30 PBHs was evidently higher that that in control group (P < 0.05 - 0.01). But the PI exhibited no obvious difference between scalding and rhGH groups. While the PI in rhGH group at 96 PBHs was obviously higher than that in both scalding and control groups (P < 0.01). The intestinal mucosal epithelial apoptotic rate in scalding group was significantly higher than that in control group (P < 0.01), while that in rhGH group was evidently lower than that in scalding and control groups (P < 0.05 - 0.01).

CONCLUSIONrhGH could promote postburn intestinal mucosa epithelial proliferation in slow - action manner and inhibit intestinal mucosal epithelial apoptosis with rapid and obvious effects. As a result, the intestinal mucosal epithelial injury could be ameliorated by rhGH by means of its inhibiting roles and the normal morphological structure of intestinal mucosa was maintained ad hoc.

Objective:To investigate the safety of minimally invasive liver resection for resectable hepatocellular carcinoma (HCC) complicated with portal hypertension.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 807 patients with resectable HCC who underwent minimally invasive liver resection in 8 medical centers, including Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine et al, from June 2011 to November 2022 were collected. There were 670 males and 137 females, aged 58(50,66)years. Of the 807 patients, 173 cases with portal hypertension were divided into the portal hypertension group, and 634 cases without portal hypertension were divided into the non-portal hypertension group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and post-operative situations; (3) subgroup analysis. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.001. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was constructed using the non-parameter rank sun test. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 807 patients, 268 cases were successfully matched, including 134 cases in the portal hypertension group and 134 cases in the non-portal hypertension group. The elimination of the tumor diameter and robot-assisted surgery confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. The occlusion time of porta hepatis, cases with intraoperative blood transfusion, cases with postoperative complication, cases with complication >Ⅱ grade of Clavien-Dindo classification, cases of Clavien-Dindo classification as Ⅰ grade, Ⅱ grade, Ⅲ grade, Ⅳ grade, cases with liver related complication were 27.0(15.0,43.0)minutes, 33, 55, 15, 13, 29, 14, 1, 37 in the portal hypertension group, versus 35.0(22.0,60.0)minutes, 17, 25, 5, 14, 9, 4, 1, 13 in the non-portal hypertension group, showing significant differences in the above indicators between the two groups ( Z=-2.15, χ2=6.30, 16.39, 4.38, 20.72, 14.16, P<0.05). (3) Subgroup analysis. Results of subgroups analysis showed that in cases with major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 243.5(174.6,296.3)minutes, 200.0(150.0,600.0)mL, 7.5(6.0,13.0)days in the portal hypertension group, versus 270.0(180.0,314.5)minutes, 200.0 (75.0,450.0)mL, 7.0(5.5,10.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.54, -1.73, -0.92, P>0.05). In cases with non-major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 8.0(5.0,10.0)days in the portal hypertension group, versus 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.5,9.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-1.39, -0.10, 1.05, P>0.05). In cases with anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 210.0(150.0,285.0)minutes, 150.0(50.0,200.0)mL, 8.0(6.0,9.3)days in the portal hypertension group, versus 225.5(146.3,306.8)minutes, 100.0(50.0,250.0)mL, 7.0(6.0,9.0)days in the non-portal hypertension group, showing no significant difference in the above indica-tors between the two groups ( Z=-0.75, -0.26, -0.91, P>0.05). In cases with non-anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 173.5(120.0,231.5)minutes, 175.0(50.0,300.0)mL, 7.0(5.0,11.0)days in the portal hyper-tension group, versus 186.0(123.0,262.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.0,9.5)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.97, -1.12, -0.98, P>0.05). Conclusion:Minimally invasive liver resection or even major liver resection is safe and feasible for screened HCC patients complicated with portal hyper-tension, but attention should be paid to the prevention and treatment of postoperative complications.
