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: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: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 double-“ U” embedding and pursestring suture and binding pancreaticojejunostomy for the prevention of pancreatic fistula.Methods The retrospective cohort study was adopted.The clinical data of 208 patients who underwent pancreaticojejunostomy at the Hunan Provincial People's Hospital from March 2011 to March 2015 were collected.Of 208 patients,106 patients undergoing double-“ U” embedding and pursestring suture and binding pancreaticojejunostomy were allocated into the double-“ U” group and 102 patients undergoing Child pancreaticojejunostomy were allocated into the Child group.Observation indicators included (1) surgical effects:anastomosis time,postoperative pancreatic leakage,duration of hospital stay,(2) follow-up situations.The follow-up using telephone interview and outpatient examination was performed to detect postoperative long-term complications and recovery of patients by abdominal ultrasound or computed tomography (CT) at every 6 months postoperatively up to September 2015.Measurement data with normal distribution were represented as x ± s and comparison between groups was analyzed by t test.Count data were analyzed using the chi-square test.Results (1) Surgical effects:208 patients underwent successful surgery without occurrence of death.The anastomosis time was (13.0 ± 1.5) minutes in the double-“ U” group and (20.0 ± 1.6) minutes in the Child group,with a statistically significant difference between the 2 groups (t =4.713,P ＜ 0.05).Two patients in the double-“ U” group were complicated with grade A of pancreatic leakage,including 1 of 36 patients with normal pancreatic remnant and 1 of 70 patients with fibrotic pancreatic remnant.Nine patients in the Child group were complicated with pancreatic leakage,including 6 in grade A,1 in grade B and 2 in grade C,and there were 6 of 33 patients (4 in grade A,1 in grade B,1 in grade C) with normal pancreatic remnant and 3 of 69 patients (2 in grade A,1 in grade C) with fibrotic pancreatic remnant.There were statistically significant differences in the pancreatic leakage between the 2 groups and among the patients with normal pancreatic remnant in the 2 groups (x2 =2.951,4.994,P ＜ 0.05).The duration of postoperative hospital stay was (13.5 ± 1.2)days in the double-“U” group and (15.7 ± 2.6)days in the Child group,with a statistically significant difference (t =1.011,P ＜ 0.05).No readmission in the 2 groups occurred.(2) Followup situations:91 of 106 patients in the double-“U” group were followed up for 6-54 months with a median time of 30 months.During the follow-up,8 patients were dead,12 patients didn't undergo reoperation due to multiple metastases in the liver,lung and greater omentum,4 and 4 patients were respectively complicated with relapsing pancreatitis and refluxing cholangitis,and other patients had good conditions without the occurrence of diabetes,diarrhea,indigestion and hypopancreatism.Eighty-eight of 102 patients in the Child group were followed up for 6-54 months with a median time of 25 months.During the follow-up,10 patients were dead,11 patients didn't undergo reoperation due to multiple metastases in the liver,lung and greater omentum,6 and 6 patients were respectively complicated with relapsing pancreatitis and refluxing cholangitis,and other patients had good conditions without the occurrence of diabetes,diarrhea,indigestion and hypopancreatism.Conclusion Double“U” embedding and pursestring suture and binding pancreaticojejunostomy for the prevention of pancreatic fistula can reduce the suture time,incidence of pancreatic leakage and duration of postoperative hospital stay,and it is especially suitable for the patients with normal pancreatic remnant.

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 evaluate the imaging changes of the arterial wall and lumen at the site of intracranial large artery lesions with high-resolution magnetic resonance imaging (HR-MRI) before and after Wingspan stent implantation.Methods From December 2013 to December 2014,9 patients with symptomatic intracranial arterial stenosis (stenosis rate:70%-99%) admitted to the Department of Interventional Neuroradiology,Xuanwu Hospital,Capital Medical University were enrolled retrospectively.The sites of the lesions included middle cerebral arteries,basilar artery,and intracranial segment of vertebral artery.Head 3D HR-MRI technique was used to analyze and compare the changes of the tube-wall enhancement areas in the lesion sites through image registration and matching.The consistency of stenosis rates measured by HR-MRI and DSA was compared through Pearson correlation analysis and Bland-Altman Plot.Results The success rate of technique was 100% without related complications.(1) After Wingspan stent implantation,the gadolinium enhancement in the vascular walls of the stenosis sites was decreased significantly compared with that before procedure.The area of enhancement decreased was 87±16% after stent implantation compared with before implantation,and the difference was statistically significant (t=2.325,P=0.049).(2) Before stent implantation,the mean stenosis rates of the HR-MRI and DSA measurements were 82±6% and 82±8% respectively,and the difference was not statistically significant (t=0.051,P=0.961);after procedure,the mean stenosis rates of HR-MRI and DSA measurements were 16±12% and 21±12% respectively,and the difference was not statistically significant (t=1.345,P=0.216).(3) The Pearson correlation coefficients of HR-MRI and DSA for stenosis rate measurement before and after stent implantation were 0.347 (P=0.361) and 0.545 (P=0.129) respectively.Bland-Altman statistical images showed that most of the data points were within the consistency limit (x-±1.96 s).Conclusions As an in vivo noninvasive imaging means,HR-MRI can be used to assess the changes of vascular walls of the lesion sites,the vascular lumen,and the original plaques after the intracranial stent release.It can also be used to evaluate the reconstruction of intracranial arterial walls.
