Objective:To study the indications and clinical efficacy of video assisted small incision in treatment of infected pancreatic necrosis.Methods:A retrospective study was conducted on 27 patients with infected pancreatic necrosis treated by video assisted small incision at the Department of Pancreatic and Splenic Surgery, Hunan Provincial People's Hospital, from January 2018 to December 2019. The surgical approach, operation time, intraoperative blood loss, postoperative hospital stay and complications were analysed. Postoperative follow-up was carried out at outpatients’ clinic, and the patient's time to full recovery and long-term complications were studied.Results:The 27 patients successfully underwent the operations. There were 22 males and 5 females, aged (50.6±6.2) years. The treatment results were analyzed according to the different surgical approaches: the retroperitoneal approach group ( n=4); the omental sac approach group (n=14); the intercostal space approach group ( n=2); and the combined approach group ( n=7). The operation time was (85.3±31.6)min. The intraoperative blood loss was 65.0(45.2, 121.4)ml. The postoperative hospital stay was 23.0(12.5, 36.1)days. The incidence of complications (Clavien-Dindo grade Ⅲ and above) was 14.8%(4/27). There were 2 patients in this study who were admitted to the intensive care unit due to postoperative hemorrhage: 1 patient responded well to conservative treatment and the remaining patient required interventional treatment. Another patient because of poor results, underwent debridement by laparotomy 2 weeks after the operation. There was 1 patient who developed grade C pancreatic fistula which was cured by surgical treatment 6 months later. On follow-up, 2 patients developed colonic fistula 2 weeks after surgery and 2 patients gastric fistula 1 week and 3 weeks after surgery. These patients responded to conservative treatment. Conclusion:With proper case selection, video assisted small incision could safely and effectively be used to treat infected pancreatic necrosis.

Objective:To evaluate the influence of minimally invasive corticotomy on the treatment time and molar anchorage of adult orthodontic extraction cases.Methods:60 adult cases of Angle Class Ⅰ crowding malocclusion were devided into 3 groups (n =20) and treated by orthodontic treatment wtih minimally invasive corticotomy(group A),orthodontic treatment with classic modified corticotomy(group B) and routine orthodontic treatment (group C) respectively.Time needed for leveling and alignment,space closure,delicate adjustment,total treatment time and mesial sagittal antedisplacement of first molar anchorage were compared among the 3 groups.Results:Time needed for leveling and alignment of orthodontic treatment of group A,B and C was (5.64 ± 2.57),(4.91 ± 3.31) and (8.87 ± 3.75) months respectively(C vs A or B,P ＜ 0.01).Time needed for space closure of group A,B and C was (6.84 ± 2.69),(6.64 ± 3.87) and (8.63 ± 3.29) months respectively(C vs A or B,P ＜0.01).Time needed for delicate adjustment showed no significant difference among the 3 groups(P ＞ 0.05).Total treatment time of group A,B and C was (16.07 ± 6.21),(15.77 ± 5.11)and (21.94 ± 5.74) months respectively (C vs A or B,P ＜ 0.01).There was on statistical difference of mesial sagittal antedisplacement of first molar anchorage among the 3 groups.Conclusion:Minimally invasive corticotomy can shorten the orthodontic treatment time,but can not decrease the retraction resistance of the anterior teeth.

Objective: To study the protective effect of compound extract of soybean, wolfberry and hawthorn on chemical liver injury in mice respectively. Methods:The mice were randomly divided into 5 groups:control(A), liver injury control(B)and 0.06(C)?0.20(D)?0.60(E) g/(kg?bw) compound extract group. The liver injury models were induced by CCl 4 and ethanol in mice respectively. After 4 weeks, for the former, the serum ALT and AST content were measured and the liver pathological change was observed. For the latter, the liver MDA, GSH, and TG content were measured and fat droplets staining in the ice pathological slice were observed . Results: 1.CCl 4 liver injury models:the content of serum ALT of group D and the AST of group D and E were decreased. Compared with normal group, the hepatic pathological changes of the compound extract group was mainly fatty and ballon degeneration, and that of the CCl 4 group was mainly hepatic cytoclasis. 2.Ethanol liver injury models: the content of liver MDA of group C, E and the TG of group C, D, E were all decreased, and the fatty degeneration scores of group C, D were lower, both compared with ethanol group. Conclusion: Compound extract of soybean, wolfberry and hawthorn has the protective effect on liver injuries induced by both CCl 4 and ethanol in mice.

Objective:This work aims determine the expression of the neurotensin (NTS) gene in hepatocellular carcinoma (HCC) subgrouping using immunohistochemical staining (IHC) as well as to evaluate the correlation between the activation of NTS/IL-8 pathway in HCC and inflammatory response in microenvironment and epithelial mesenchymal transition (EMT) in cancer and in the prognosis of patients. Methods:Tumor tissues and corresponding adjacent normal tissue were collected from 64 cases of HCC patients. The expression levels of NTS protein and multiple inflammation and EMT-related proteins, including IL-8, VEGF, MMP9, CD68, E-Cadherin,β-Catenin, and Vimentin, were examined in 64 cases of paraffin-embedded HCC tissues using the immunohistochemistry (IHC) staining method. The clinical outcome and overall survival (OS) among 64 cases of HCC patients were compared. Results:We found that the frequency of NTS-expressing tissues among all HCC samples was 17.19%(11/64). Significantly increased IL-8 protein was confirmed in 90.91%of NTS+HCC samples and was positively correlated with the levels of NTS protein in cancer tissues (P=0.036), which implied the dysfunctional activation of NTS/IL-8 pathway in HCC. The levels of VEGF and MMP9 were significantly correlated with the co-expression of NTS and IL-8 in HCC. Evident features of EMT, including decreased membrane expression of E-Cadherin and increased accumulation of cytoplasmicβ-Catemin and Vimentin, were found in NTS+IL-8+samples. The co-expression of NTS and IL-8 in cancer was significantly correlated with the clinical outcomes of patients, as the mortality rate of NTS+IL-8+HCC patients is 2.5-fold higher than that of others after surgery (P=0.022).Accordingly, the OS of NTS+IL-8+HCC patients significantly decreased (24.65±4.45 m vs. 75.79±16.32 m, P=0.013), and these patients are at a higher risk of death at an expected hazard ratio (HR) of 3.457. Conclusion:The NTS/IL-8 pathway is dysfunctionally activated in a subgroup of HCC samples. Highly expressed NTS is associated with increased inflammatory response in microenvironment, enhanced EMT in cancer, and worse prognosis in HCC patients.

Objective To investigate the efficacy of duodenum-preserving pancreatic head resection (DPPHR) for the treatment of chronic pancreatitis combined with type Ⅰ and Ⅲ pancreatic duct stones.Methods The clinical data of 55 patients with chronic pancreatitis and type Ⅰ and Ⅲ pancreatic duct stones who were admitted to the People's Hospital of Hunan Province from June 2008 to June 2013 were prospectively analyzed.All the patients were randomly divided into the pancreatoduodenectomy (PD) group (27 patients) and the DPPHR group (28 patients).There were 18 patients with chronic pancreatitis and type Ⅰ pancreatic duct stones and 9 patients with chronic pancreatitis and type Ⅲ pancreatic duct stones in the PD group.There were 16 patients with chronic pancreatitis and type Ⅰ pancreatic duct stones and 12 patients with chronic pancreatitis and type Ⅲ pancreatic duct stones in the DPPHR group.Patients in the PD group received PD + Child anastomosis + end-toside pancreato jejunal anastomosis + pancreatic stent placement + end-to-side cholangiojejunostomy.Patients in the DPPHR group received free of duodenum + pancreatic duct incision + resection of pancreas at 1 cm ahead of the pancreatic duct + extraction of the pancreatic duct stones + pancreaticoduodenal Roux-en-Y anastomosis.Patients were followed up via out-patient examination till December 2013.The measurement data were analyzed using the t test or Mann-Whitney U test,and the count data were analyzed using the chi-square test.Results During the operation,2 patients in the PD group were converted to the DPPHR group and 1 patient in the DPPHR group was converted to the PD group.No patient died during the perioperative period,and the symptoms including abdominal pain and diarrhea were alleviated at postoperative week 2.The operation time,blood loss,duration of postoperative hospital stay,total expenses and incidence of complications were (7.5 ± 1.6) hours,(460 ± 88) mL,(18.0 ± 3.5) days,(7.8 ± 2.1) × 104 yuan,19.2％ (5/26) in the PD group,and (4.0 ± 1.0) hours,(120 ± 36) mL,(9.5 ± 2.9) days,(3.9 ± 1.2) × 104 yuan,3.4％ (1/29) in the DPPHR group,there were no significant differences in the operation time,blood loss,duration of hospital stay,total expenses and incidence of complications between the 2 groups (t =9.358,11.365,6.325,8.647,x2 =3.976,P ＜ 0.05).Fifty-three patients were followed up,with the median time of 33 months (range,6 months to 5 years).No patient died during the follow-up.Twenty-four patients in the PD group were followed up,2 patients had slight abdominal pain,1 patient had severe abdominal pain due to pancreatic duct stenosis,and the symptom was alleviated after resection of partial pancreas ; the condition of 12 patients was improved among the 19 patients with diabetes.Twenty-nine patients in the DPPHR group were followed up,2 patients had slight pain; the condition of 16 patients were improved among the 22 patients with diabetes.Conclusion DPPHR is an ideal surgical procedure for patients with chronic pancreatitis and type Ⅰ and Ⅲ pancreatic duct stones.

Objective To investigate the role of tumor necrosis factor-α (TNF-α) on eryptosis.Methods Erythrocytes isolated from mice were put under the treatment of TNF-α at the dose of 1ng/ml for 6,12,24,48 and 72 h,or at different concentrations of 0.1,1 and 10 ng/ml for 24 h.The forward scatter (FSC),phosphatidylserine (PS)exposure and ceramide formation were determined by flow cytometry.Results Compared to control group,the decrease of FSC ((81.5 ± 1.02)％ vs (87.6 ± 0.55)％,P＜0.05),the increasment of membrane PS exposure level and ceramide content ((5.5±1.07)％ vs (2.7±0.17)％,(2.1±0.23)％ vs (0.7±0.26)％,P＜0.01) were observed in erythrocyte under the treatment of TNF-α for 24 h with more obvious tendency over time.Conclusions TNF-α can trigger cell shrinkage,and promote PS exposure and ceramide formation on the membrane of erythrocyte.

Objective:To study the value of metastatic positivety in lymph nodes group 8a in deciding on extended lymph node dissection in pancreaticoduodenectomy(PD) for pancreatic head cancer.Methods:A retrospective study on 165 patients with pancreatic head cancer treated with PD at the Department of Pancreas and Spleen Surgery, Hepatobiliary Hospital of Hunan Provincial People's Hospital between January 2014 to June 2019 was performed. There were 101 males and 64 females with ages ranging from 38 to 75 (median 57) years. Patients who underwent standard lymph node dissection were included in the standard group ( n=88), and extended lymph node dissection in the extended group ( n=77). These patients were further divided into 4 subgroup. Subgroup A (standard PD in patients with negative nodes in group 8a, n=61), Subgroup B (extended PD in patients with negative nodes in group 8a, n=47), Subgroup C (standard PD in patients with positive nodes in group 8a, n=27), and Subgroup D (extended PD in patients with positive nodes in group 8a, n=30). The operation time, intraoperative blood loss, postoperative survival rates, complications were compared among the groups and subgroups. Results:The operation time and intraoperative blood loss of the standard group were (456.8±30.4) min and (264.28±101.14) ml, respectively, which were significantly lower than the extended group of (507.1±45.7) min and (388.9±155.3) ml (all P<0.05). The incidence of postoperative complications in the extended group (31.2%, 24/77) was significantly higher than that in the standard group (14.8%, 13/88) ( P<0.05). When compared with subgroup B, the cumulative survival rate of patients in subgroup A was not significantly different ( P>0.05). However, the cumulative survival rate of patients in subgroup C was significantly lower than that in subgroup D ( P<0.05). The cumulative survival rate of subgroup A was also significantly better than that of subgroup C ( P<0.05). There was no significant difference in the cumulative survival rates between group B and group D ( P>0.05). Conclusions:PD with extended lymph node dissection improved the survival rates in patients with cancer of the head of the pancreas with positive lymph nodes in group 8a. For these patients, extended lymph node dissection is recommended. With negative lymph nodes in group 8a, standard lymph node dissection is recommended.
