ABSTRACT
Objective:To evaluate whether vagus nerve-guided robotic splenectomy and azygoportal disconnection (VNRSD) is feasible and safe and to determine whether VNRSD can be competent for well protecting vagus nerve.Methods:In this prospective clinical study, 12 cirrhotic patients with portal hypertension, hypersplenism and esophagogastric variceal bleeding (EVB) who accepted VNRSD at the Clinical School of Medicine of Yangzhou University between January 2022 and March 2022 were included, including 5 females and 7 males, aged (56.6±11.6) years old. Clinical data such as visual analog scale (VAS) pain score, conversion to laparotomy, esophagogastric variceal bleeding, and death were collected. The patients were asked to reexamine in the outpatient department 1 month after the operation, and the diarrhea, delayed gastric emptying and epigastric fullness were followed up.Results:VNRSD was successfully performed in all patients. There was no conversion to open or laparoscopic operations. The operation time was (170.0±16.8) min, blood loss was (60.8±11.3) ml, VAS pain score on the first day was (2.2±0.9) scores, and the postoperative hospital stay was (7.7±0.7) d, the four patients had main portal vein system thrombosis on the 7th day after operation. At the first day after operation, all patients were mange to take semi-fluid and off-bed activity. There were no incisional complications, pneumonia, gastric fistula, pancreatic fistula, and abdominal infection. No patients suffered from diarrhea, delayed gastric emptying, and epigastric fullness. None of the patients suffered from esophagogastric variceal bleeding, hepatic encephalopathy or death after operation and one month after operation, and the esophagogastric variceal were significantly improved. And no patient complained of abdominal distension or diarrhea.Conclusion:VNRSD procedure is not only technically feasible and safe, but also effectively protects anterior and posterior vagal trunks and all their branches, completely eradicating digestive system complications.
ABSTRACT
Objective:To evaluate the clinical efficacy of laparoscopic splenectomy and azygoportal disconnection (LSD) with intraoperative endoscopic variceal ligation (LSDL) in the treatment of esophagogastric variceal bleeding (EVR).Method:In this study,90 cirrhotic patients with esophagogastric variceal bleeding (EVB) were divided to receive either LSD ( n=45) or LSDL ( n=45) from Jan 2020 and Dec 2021. Results:There were no significant differences in estimated blood loss, incidence of blood transfusion, time to first flatus, off-bed activity and postoperative hospital stay between the two groups (all P>0.05). Compared with LSD group, operation time was longer in LSDL group[ (140±21) min vs. (150±19) min, t=2.420, P=0.018]. LSDL was associated with significantly decreased EVR rate in one year follow-up (2% vs. 18%, P=0.030). Univariate analysis and multivariate logistic regression revealed that LSDL was a significant independent protective factor for EVR as compared with LSD ( P<0.05). Conclusion:LSDL procedure is not only technically feasible and safe, it also contributed to lower postoperative EVR risk than single LSD.
ABSTRACT
Objective:To investigate the value of liver fibrosis serum markers in predicting esophagogastric variceal re-bleeding (EGVR) after laparoscopic splenectomy and azygoportal discon-nection (LSD).Methods:The prospective study was conducted. The clinical data of 155 cirrhotic portal hypertension patients with EGVR after LSD in the Clinical Medical College of Yangzhou University from September 2014 to January 2017 were selected. Observation indicators: (1) grouping situations of the enrolled patients; (2) risk factors analysis for postoperative EGVR; (3) prediction of postoperative EGVR; (4) follow-up. Follow-up was conducted using telephone interview, outpatient examination and hospitalization. Patients were followed up once every 3 months after operation to detect occurrence of EGVR and survival of patient up to January 2018. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data wite skewed distribution were represented as M(range), and comparison between groups was conducted using the non-parameter test. Count data were described as absolute numbers, and comparison between groups were conducted using the chi-square test or Fisher exact probability. Logistic regression model was used for multivariate analysis. The area under curve (AUC) of receiver operating characteristic (ROC) curve was used to estimate the diagnostic efficiency. The Youden index was used to determine the optimal cut-off point. Results:(1) Grouping situations of the enrolled patients. A total of 155 patients were selected for eligibility. There were 106 males and 49 females, aged (53±11)years. Of the 155 patients, there were 21 cases with EGVR in the postoperative 1 year and 134 cases without EGVR in the postoperative 1 year. The protein expression of laminin and collagen Ⅳ were 100.3(range, 16.1?712.2)μg/L and 68.4(range, 35.0?198.8)μg/L in patients with EGVR, vs 35.5(range, 2.0?521.2)μg/L and 43.5(range, 4.3?150.4)μg/L in patients without EGVR, showing significant differences between them ( Z=?4.55, ?4.52, P<0.05). (2) Risk factors analysis for postoperative EGVR. According to the Youden index, the optimal cut-off point of protein expression of laminin and collagen Ⅳ were 64.0 μg/L and 65.0 μg/L, respec-tively. Results of multivariate analysis showed that the protein expression of laminin ≥64.0 μg/L and the protein expression of collagen Ⅳ ≥65.0 μg/L were independent risk factors for postoperative EGVR ( odds ratio=9.69, 8.16, 95 confidence intervals as 3.05?30.82, 2.65?25.15, P<0.05). (3) Prediction of postoperative EGVR. Results of ROC curve showed that the AUC of laminin and collagen Ⅳ in predicting postoperative EGVR was 0.79 (95% confidence interval as 0.66?0.92), with sensi-tivity as 0.62 and specificity as 0.96. (4) Follow-up. All the 155 patients were followed up for 12(range, 1?12)months. During the follow-up, there were 21 of the 155 patients (13.55%) with post-operative EGVR, including 3 cases died of EGVR. Of the 21 patients with postoperative EGVR, there were 6 cases with postoperative EGVR during the first month after operation including 2 cases died, 5 cases with postoperative EGVR at postoperative 1?3 month, 6 cases with postoperative EGVR more than 3 month and less than 6 month after operation and 4 cases with postoperative EGVR at postoperative 6?12 months including 1 case died at postoperative 12 month. Conclusions:Laminin and collagen Ⅳ show satisfactory ability to predict EGVR after LSD.
ABSTRACT
Acute suppurative cholecystitis is a complex acute abdomen in general surgery, which usually occurs in middle-aged and elderly people. With the improvement of living standards and the aging of the population, the incidence of the disease is increasing year by year. Elderly patients have certain clinical particularities, and they are often combined with other underlying diseases such as cardiovascular and cerebrovascular diseases. Therefore, specific programs should be implemented for different situations during patient treatment, and a more complete risk assessment should be carried out. The preferred treatment for acute suppurative cholecystitis is surgery, but for patients with poor general conditions or intolerable surgery, percutaneous transhepatic gallbladder drainage may be a good alternative. This article reviews the clinical characteristics, diagnosis and treatment of acute suppurative cholecystitis in the elderly.
ABSTRACT
Objective:To introduce the usefulness and advantages of needle-type choledochotomy in laparoscopic common bile duct exploration.Methods:A retrospective analysis for the data of 1 107 patients who successfully implemented laparoscopic common bile duct exploration in Subei People′s Hospital of Jiangsu Province from January 1, 2013 to December 31, 2020 were applied. All cases were divided into the study group 662 cases with needle-type choledochotomy) and the control group (445 cases with non-needle-type choledochotomy) according to the manipulation of common bile duct incision. The time-cost, incidences of bleeding and bile leakage, as well as the recurrence rate of bile duct stone and the incidence of bile duct stenosis were observed and compared between the two groups. Normally distributed data were expressed as mean±standard deviation ( Mean± SD) and compared by t test while count data were expressed as frequency or percentage and compared by chi-square test or Fisher′s exact test. Results:The bile duct incision time and bleeding rate were (14.45±2.46) s and 25.1% in the study group, (104.48±15.32) s and 68.1% in the control group, respectively. The differences between the two groups were statistically significant ( P<0.001). The incidence of stone recurrence, biliary leakage, and bile duct stricture were 3.0%, 3.6% and 0.3% in the study group, 4.9%, 5.6% and 0.4% in the control group, respectively. There were no statistically significant differences between the two groups ( P>0.05). Conclusion:Needle-type bile duct incision can be used as a routine manipulation in laparoscopic common bile duct exploration for its time-saving, less bleeding, safe and easy to handling.

ABSTRACT
Intrahepatic cholangiocarcinoma(ICC) is a malignant tumor that originates in the epithelium of the proximal proximal to the second-degree bile ducts and has a high degree of malignancy. The causes of ICC are widely geographically diverse. Pathogenesis of ICC involves multiple molecular alterations at the level of genome, epigenome and stromal environment resulting in several deregulated signal transduction pathways. There are three types of pathological classification: mass-forming, periductal infiltrating, and intraductal growth. The mixed type of mass-forming + periductal infiltrating has the highest degree of malignancy. Early diagnosis of ICC is not easy, and tumor biomarkers such as CA19-9, CEA and so on, have some reference values, and multiple imaging examinations are needed to confirm each other. The effect of surgery mainly depends on the characteristics of the tumor, the vascular invasion of the tumor, the resection margin of the tumor and lymphatic metastasis. Lymph node dissection is controversial. If local lymphatic metastasis is identified, standardized lymph node dissection can improve ICC prognosis. Some ICC patients benefit from laparoscopic staging. In experienced centers, minimally invasive treatment can provide oncological outcomes similar to open resection for specific ICC patients. Liver transplantation is feasible in early ICC patients, but further clinical validation is needed.
ABSTRACT
Objective To study the functions and mechanisms of glutamine 1 (GLS1) in intrahepatic cholangiocarcinoma (ICC) cell to 5-fluorouraeil (5-FU) chemosensitivity.Methods The expression and relation between GLS1 and major vault protein (MVP) in cholangiocarcinoma were analyzed by bioinformatics database.Western blot and immunohistochemistry were used to detect the expression of GLS1 and MVP in 42 ICC tissues,and the correlation between GLS1 and MVP was studied by statistics.The regulation of GLS1 in ICC cell were evaluated by siRNA interference and pcDNA overexpression,and then tested the interference and overexpression efficiency of GLS1 by Western blotting.The chemosensitivity to 5-Fu was tested by cell counting kit-8 (CCK-8).Results The expression of GLS1 and MVP in ICC tissues was significantly up-regulated (tGLSI =3.963;tMVP =3.131,P ＜ 0.05),and the expression of GLS1 was positively correlated with MVP(r2 =0.351 7,P ＜ 0.05).Knockdown of GLS1 in QBC939 cells enhanced chemosensitivity of QBC939 cells to 5-Fu and notably downregulated MVP expression,while enforced expression of GLS1 in RBE cells promoted MVP expression and reduce cell sensitivity to 5-fluorouracil chemosensitivity.Conclusions GLS1 regulates the chemosensitivity of ICC cells to 5-Fu,and its mechanism may relates to the regulation of MVP.
ABSTRACT
OBJECTIVE@#To investigate the effect of vitamin D on microRNA-21(miR-21) expression and migration and invasion of human placental trophoblast cells.@*METHODS@#The changes in the expression of miR-21 were detected using RT-qPCR in HTR-8/SVneo cells following stimulation by vitamin D at different doses for 24, 48 and 72 h.HTR-8/SVneo cells transfected with miR-21 mimic or inhibitor with or without vitamin D treatment were examined for changes in cell migration and invasion abilities using Transwell assay, and Western blotting was used to detect protein expressions of E-cadherin, fibronectin, and MMP9.@*RESULTS@#Vitamin D obviously inhibited the expression of micoRNA-21 in HTR-8/SVneo cells in a concentration-and time-dependent manner.Transfection with the miR-21 mimic significantly inhibited the migration and invasion of HTR-8/SVneo cells, and this inhibitory effect was abolished by treatment with vitamin D; transfection with miR-21 inhibitor obviously promoted the migration and invasion of HTR-8/SVneo cells, and these effects were not significantly affected by vitamin D treatment.@*CONCLUSIONS@#Vitamin D may promote trophoblast cell migration and invasion to accelerate the development of preeclampsia by down-regulating the expression of miR-21.

ABSTRACT
Portal vein system thrombosis (PVST) is a common complication in patients after open or laparoscopic splenectomy or combined with devascularization.It may endanger the health of the patients after surgery and even potentially endanger the patient's life in severe cases.The formation and development of PVST is affected by many factors,and the correct use of anticoagulant drugs play a vital role in the prevention and treatment of PVST in postoperative patients with cirrhotic portal hypertension.This article discusses the advances in research on the prevention and treatment of PVST after open or laparoscopic splenectomy or combined with devascularization with anticoagulant drugs,and reviews the current anticoagulant properties and recommends of anticoagulant therapy,further guides the use of clinical anticoagulant drugs to reduce the incidence of PVST and improve the quality of life in patients with such surgery.
ABSTRACT
Tumor heterogeneity is one of the common phenomena of malignant tumors, and the heterogeneity of hepatocellular carcinoma is significant. Despite some treatments such as surgical resection, chemotherapy and radiotherapy in the primary phage of hepatocellular carcinoma have been used, the prognosis of patients remains poor, which is closely related to the heterogeneity of hepatocellular carcinoma. Therefore, exploring the heterogeneity of hepatocellular carcinoma has important clinical significance for improving the therapeutic effect of hepatocellular carcinoma. This article reviews the heterogeneity of hepatocellular carcinoma from an epigenetic perspective and explores the possible intrinsic epigenetic molecular mechanisms underlying the heterogeneity of hepatocellular carcinoma.

The self-made general questionnaire,the Eysenck personality questionnaire,the positive and negative symp-tom scale were used in this survey and the color preference was compared with the normal control group. Re-sults (1)The preference degree was significantly different in green(Z＝－2.587,P＝0.010),blue(Z＝－2.708,P＝0.007),white(Z＝－2.733,P＝0.006) and grey(Z＝－7.409,P＜0.01) between the two groups, and the sequence of color preference was consistent(r＝0.750,U＝2.710,P＜0.01).(2) Gender,age,place of residence,physical disease,starting age,disease subtype,positive symptoms,negative symptoms,hospitaliza-tion time,hospitalization frequency,psychoticism and neuroticism,internal and external factors were signifi-cantly related to color preferences(r＝0.010-0.216 or r＝－0.122-－0.054,P＜0.05),which would be the influ-ence factors to color preferences(β＝0.104-0.055 or β＝－0.091- －0.056,P＜0.05). Conclusion The most significant color preferences for patients with schizophrenia are red and black, which may be related to their cognitive function and personality characteristics.
ABSTRACT
Objective To investigate the clinical safety and value of sequential therapy combining laparoscopic splenectomy and azygoportal disconnection with postoperative endoscopic variceal ligation (EVL) for portal hypertensive variceal bleeding.Methods From February 2012 to March 2016,114 patients underwent sequential laparoscopic splenectomy plus azygoportal disconnection and periodical postoperative endoscopic variceal ligation.Results were compared with those who underwent laparoscopic splenectomy and azygoportal disconnection without postoperative endoscopic variceal ligation in a group of 105 cases.Results Between the two groups oesophageal variceal re-bleeding (EVR) rates during first postoperative 3 months was not significantly different (P ＞ 0.05),however,sequential therapy group was associated with lower EVR rates during the periods ranging from 1 to 12 months,and 4 to 12 months compared with non-sequential therapy group (all P ＜ 0.05).Dynamic changes in the diameter of oesophageal varices and EVL rates in sequential therapy group both decreased gradually and significantly over the 12-month follow-up period (all P ＜0.01).No one in sequential therapy group suffered EVR from 6th month onward.No patient required EVL at the 12th month in sequential therapy group.Conclusion Sequential laparoscopic splenectomy plus azygoportal disconnection and postoperative EVL for portal hypertensive variceal bleeding is safe,feasible and effective in decreasing postoperative EVR rates.

Objective To investigate the clinical safety and value of vagus nerve-preserving versus conventional laparoscopic splenectomy and azygoportal disconnection.Methods A total of 60 cirrhotic patients with bleeding portal hypertension undergoing modified laparoscopic splenectomy and azygoportal disconnection between Apr 2015 and Sep 2016 were retrospectively analyzed.Patients were divided into nonvagus nerve-preserving (n =37) and vagus nerve-preserving group (n =23).Results Operative time (169 ± 42) min,and incidences of postoperative complications (102/370),delayed gastric emptying (35/37),epigastric fullness (22/37),diarrhea (26/37) in non-vagus nerve-preserving group were all more than those in vagus nerve-preserving group [(147 ± 21) min,(21/230),(2/23),(2/23),(2/23)] (t =2.684,x2 =29.583,44.272,15.229,21.606,all P ＜ 0.05).There was no significant between-group difference in body weight at admission and on postoperative day 7 (POD 7) between the two groups.However,body weight in vagus nerve-preserving group was significantly higher on postoperative 6 month (POM) compared with that in non-vagus nerve-preserving group [(63 ± 10) kg vs.(70 ± 12) kg,t =2.546,P ＜ 0.05].There was no significant between-group difference in ALB levels at admission and on POD 7 between the two groups.However,ALB levels in vagus nerve-preserving group at POM 6 were significantly higher than those in non-vagus nerve-preserving group [(42 ±6) g/L vs.(46 ±5) g/L,t =-2.607,P ＜ 0.05].Conclusion Vagus nerve-preserving laparoscopic splenectomy and azygoportal disconnection for cirrhotic portal hypertension is safe,feasible and with good therapeutic effect.
ABSTRACT
Objective To evaluate the feasibility and safety of modified laparoscopic pyloroplasty (LP) during laparoscopic splenectomy and azygoportal disconnection (LSD) for the prevention of postoperative gastroparesis.Methods A total of 31 cirrhotic patients with bleeding portal hypertension admitted to our department between Jan 2015 and Aug 2015 were retrospectively reviewed.Patients were divided into LP group (n =14) and non-LP group (n =17).Results One month postoperatively,the incidence of bloating was significantly lower in the LP group than in the non-LP group [21％ vs.88％,P ＜0.05].Three months postoperatively,the LP group had significantly lower incidences of nausea (0 vs.35％,P ＜ 0.05) and bloating (14 ％ vs.76％,P ＜ 0.05) than the non-LP group.The incidence of gastric retention confirmed by electronic gastroscopy at 3 and 6 months postoperatively in the LP group was significantly lower than that in the non-LP group (14％ vs.94％,P ＜ 0.01;14％ vs.88％,P ＜ 0.01,respectively).Conclusion It is safe,feasible and with good therapeutic effect for modified laparoscopic pyloroplasty during laparoscopic splenectomy and azygoportal disconnection for the prevention of postoperative gastroparesis.
ABSTRACT
Metabolic deregulation is a major essential feature in the development of cancer,wbich also correlates with invasion and metastasis of tumor.Metabolic characteristic of tumor cells which deviate significantly from those of normal cells.In this review,we summarize the research about the relationship between cellular metabolic abnormalities and capability of tumor's invasion and metastasis.
