ABSTRACT
Objective:To evaluate the inflammatory factors effects of early endoscopic therapy for elderly patients with acute biliary pancreatitis (ABP) and its clinical efficacys.Methods:206 elderly patients with ABP admitted from Jan. 2010 to Dec. 2019 were divided into observation group (102 cases) and the control group (104 cases) according to treatment method. The observation group received endoscopic retrograde cholangiopancreatography (ERCP) , endoscopic sphincterotomy (EST) and endoscopic naso-biliary drainage (ENBD) , while the control group received conventional treatment. Clinical symptoms, changes of inflammatory factors, complications and prognosis were observed in each group.Results:CRP, SAA, IL-6, IL-8 and TNF-a after treatment were significantly lowered than those before treatment ( P<0.05) . In addition, the levels of CRP, SAA, IL-6, IL-8 and TNF-a in the observation group were significantly lower than those in the control group ( P<0.05) . The time to abdominal pain extinction, time to fever cessation, hospital stay in observation group were (3.92±1.54) , (3.63±1.41) , and (14.35±2.46) d, significantly less than those in the control group [ (5.81±1.72) , (5.45±2.13) , (19.37±3.12) d, P<0.05]. APACHE Ⅱ score of the observation group was (10.02±2.67) point after treatment, significantly lower than that in the control group [ (12.35±3.62) point, t=4.42, P<0.05]. The incidence of complications in the observation group was 10.78% after treatment, significantly lower than that in the control group [ (24.03%) , χ2=6.27, P< 0.05]. The mortality in the observation group was 1.96%, lower than 4.81% in the control group, with no statistical significance. Conclusion:Early endoscopic therapy is safe and highly effective for elderly patients with ABP, with the advantages of shorter hospital stay, quicker subsided inflammation, and lower incidence of complications.
ABSTRACT
Objective To investigate the relationship between the expression of ASPP2 mRNA and the methylation of ASPP2 gene in gastric cancer cells,to observe the inhibitory effect of 5-Aza-CdR on the growth of gastric cancer cells,to observe the effect of demethylation on the expression of ASPP2 mRNA and the methylation of ASPP2 gene in gastric cancer cells,and to explore the molecular mechanism of gastric cancer.Methods Real-time PCR was used to detect the expression of ASPP2 mRNA in two gastric cancer cells and normal gastric epithelial cells.BSP was used to detect the methylation of ASPP2 gene in two gastric cancer cells and normal gastric epithelial cells.CCK-8 was used to detect the growth inhibition rate of gastric cancer cells treated with 5-Aza-CdR of different concentrations,then they were used to detect expression of ASPP2 mRNA and the methylation of ASPP2 gene in gastric cancer cells again after the demethylation.Results ① The expression of ASPP2 mRNA in MKN-45 cells was significantly lower than that in GES-1 cells(P＜0.01).The expression of ASPP2 mRNA in MGC-803 cells was significantly lower than that in GES-1 cells (P＜0.01).There was no significant difference in MGC-803 cells and MKN-45 cells(P＞0.05).② The methylation rate of ASPP2 in MKN-45 cells was significantly higher than that in GES-1 cells (P＜0.01).The methylation rate of ASPP2 in MGC-803 cells was not significantly different from that in GES-1 cells (P＞0.05).The methylation rate of ASPP2 in MKN-45 cells was significantly higher than that in MGC-803 cells (P＜0.01).③ At the same time,the growth inhibition rate of each 5-Aza-CdR concentration group increased as the drug concentration depended.4.The expression of ASPP2 mRNA in MKN-45 cells was significantly higher than that before treatment (P＜0.01),the expression of ASPP2 mRNA in MGC-803 cells was not significantly different from that before treatment(P＞0.05).The methylation rate of ASPP2 in MKN-45 cells was significantly lower than that before treatment (P＜0.01).The methylation rate of ASPP2 in MGC-803 cells was not significantly different from that before treatment (P＞0.05).Conclusion ① Abnormal hypermethylation of ASPP2 gene in MKN-45 cells may be a molecular mechanism of decreased ASPP2 mRNA expression.② 5-Aza-CdR can inhibit the growth of MKN-45 and MGC-803 cells,and it can enhance the expression of ASPP2 mRNA in MKN-45 cells.Reversal of methylation in the promoter region of ASPP2 gene is the possible mechanism.③ Abnormal hypermethylation of the promoter region of ASPP2 gene may lead to silencing of mRNA expression that may be associated with gastric cancer.

ABSTRACT
Objective To investigate the correlation and expression of PTEN, matrix metalloproteinase-9 (MMP-9),and vascular endothelial growth factor-C(VEGF-C)in colorectal cancer.Methods The expression of PTEN, MMP-9 and VEGF-C in 102 cases of colorectal cancer tissues and 30 cases of normal colorectal tissues was detected using immunohistochemical SP method.Their correlations with cliniopathologic features were analyzed. Results The positive expression of PTEN in colorectal cancer was significantly lower than that in the controls (54.9%vs 100%, P<0.01).Both MMP-9 and VEGF-C were over expressed compared with the controls(83.3%vs 21.7%and 69.6%vs 16.7%respectively, P<0.01).The expression of PTEN was negatively correlated with that of MMP-9 and VEGF-C, and the expression of MMP-9 was positively correlated with that of VEGF-C ( P<0.05).The expressions of the three proteins in colorectal cancer tissues were not associated with age, gender, or tumor size.There were significant associations between the expression of these proteins and lymph node metastasis, distant metastasis, differentiation, and TNM staging(P<0.05).The 1, 3 and 5-year survival rates of the patients with positive PTEN were significantly higher than those of the patients with negative PTEN(P<0.05).The 1, 3 and 5-year survival rates of the patients with positive MMP-9 and VEGF-C were significantly lower than those of the patients with negative MMP-9 and VEGF-C( P<0.05) .Conclusions The decrease in the expression of PTEN and increase in MMP-9 and VEGF-C are closely correlated to the development of colorectal cancer.Their expressions may be favorable markers and useful prognostic indicators in the patients with colorectal cancer.
ABSTRACT
Objective To investigate the relationship between peri-menopausal women blood lipid level and the gallstone disease in order to provide theoretical basis for the prevention of gallbladder stone.Methods Seventy-two patients with gallbladder calculus from Department of Hepatobiliary Surgery Jinshan District Central Hospital of Shanghai and 52 healthy women coming for physical examination as the control group.Participants were divided into five age groups (20-29,30-39,40-49,50-59 and 60-69 years old) and two age stages (young period (30-40 years old) and peri-menopausal period (45-55 years old)),total cholesterol (TC),triglyceride (TG),high density lipoprotein (HDL-C),low-density lipoproteins (LDL-C) and Body Mass Index (BMI) were determined and compared between the stone group and the control group at different age stages.Results In comparison of the menopausal transition period,the stone group had significantly lower blood TC,HDL-C and LDL-C levels than the control group (TC:(4.58 ± 0.27) mmol/L vs.(5.15 ± 0.26) mmol/L,t=3.112,P ＜0.01 ;HDL-C:(1.17 ±0.11) mmol/L vs.(1.40 ±0.08) mmol/L,t =3.351,P ＜0.01 ;LDL-C:(2.71 ± 0.30) mmol/L vs.(3.15 ± 0.26) mmol/L,t =2.437,P ＜ 0.05).For the young period,there were no significant difference on blood lipid level and BMI was observed between the stone group and the control group (P ＞ 0.05).The fat HDL-C level in blood was significantly lower in the stone group in the menopausal transition period than in the young period ((1.17 ± 0.11) mmol/L vs.(1.33 ± 0.07) mmol/L,t =2.455,P ＜ 0.05).The control group had significantly higher peri-menopausal TC,TG,LDL-C levels in blood and BMI than those in the control group young period (P ＜ 0.05) ; And HDL-C level,no significant difference (TC:(5.15 ± 0.26)mmol/L vs.(4.47 ± 0.34) mmol/L,t =3.175,P ＜ 0.01 ; TG:(1.88 ± 0.39) mmol/L vs.(1.10 ± 0.24)mmol/L,t=3.066,P＜0.01;LDL-C:(3.15 ±0.26) mmol/L vs.(2.71 ±0.31) mmol/L,t =2.261,P＜0.05;BMI:(24.75±0.99) kg/m2vs.(21.73±1.11) kg/m2,t=4.217,P＜0.01).Conclnsion For perimenopausal (45-55 years old) females,decline of serum TC,HDL-C and LDL-C levels may be related to the formation of cholesterol stone.Lower HDL-C level is closely associated with formation of cholesterol stone,indicating that it may be one of the measures to prevent gallbladder stone by adjusting blood fat in perimenopausal women.
ABSTRACT
Objective To investigate the causes of repeated operations in patients with biliary diseases.Methods The clinical data of 265 patients who received repeated operations at the Jinshan Branch of Shanghai Sixth People's Hospital from January 2005 to June 2011 were retrospectively analyzed.The causes of repeated operations were analyzed. The first reoperation aimed at removing the calculi completely,repairing the injured biliary ducts and managing malignant tumors. The primary surgical procesures of the first reoperation included choledochotomy + T tube drainage,choledochotomy + Roux-en-Y choledochojejunostomy,endoscopic retrograde cholangiopancreatography + endoscopic sphincterotomy,choledochotomy + hepatectomy + T tube drainage or Rouxen-Y choledochojejunostomy,choledochotomy + biliary-endo-drainage,end-to-end anastomosis of bile duct + T tube drainage,radical or palliative resection of tumor,endoscopic biliary stent drainage or exploratory laparotomy.The second and multiple reoperations aimed at reconstructing the passage for biliary drainage. All data were analyzed using the chi-square test.Results A total of 69.8％ (120/172) of patients who had recurrent or retained calculi received first reoperation,which was significantly higher than 31.2％ ( 29/93 ) of those who received second or multiple reoperations (x2 =36.51,P ＜ 0.05 ).A total of 58.1％ (54/93) of patients who had benign stenosis of bilioenteric anastomosis received multiple reoperations,which was significantly higher than 4.1％ (7/172) than those who received first reoperation (x2 ＝ 99.32,P ＜ 0.05 ).Of the 265 patients,46 had complications.The incidence of complications of patients who receive first reoperation was 10.5％ ( 18/172),which was significantly lower than 30.1％ (28/93) of patients who received second or multiple reoperations ( x2 =13.61,P ＜ 0.05 ).Six patients died of hemorrhagic shock or multiple organ syndrome dysfunction postoperatively.The mortality rates for patients who received first reoperation and second or multiple reoperations were 1.7％(3/172) and 3.2％ (3/93),respectively,with no significant difference ( x2 ＝ 0.59,P ＞ 0.05 ).Conclusions The causes for reoperation of biliary disease are muhifactorial.Full assessment of the status of biliary diseases and ample preperation preoperatively,careful operation and precise and rational selection of operative procedures are keys to decrease the reoperative rates and perioperative complications.
ABSTRACT
Objective To study the etiological factors,clinical characteristics and diagnosis of acute pancreatitis (AP).Methods The clinical data of 217 patients with AP treated from January 2005to December 2010 in our hospital were studied retrospectively.Results The majority of patients were male (60.4％).The average age was 52.5 years.Cholelithiasiss,hyperlipidemia and trauma were the most frequent etiologic causes of AP.There were 164 patients with mild (75.6％) and 53 patients with severe (24.4％) AP.151 patients underwent surgical or endoscopical treatment (69.6 ％) while 66 patients underwent non-operative treatment (30.4 ％).14 of 53 patients with severe AP died.Conclusions AP should be treated according to the cause and the type.The key to reduce complications and increase cure rate is to find the cause of AP and then treat the underlying disease.
ABSTRACT
Objective To explore etiological factors, clinical characteristic and diagnosis of acute recurrent pancreatitis (ARP). Methods Clinical data of 68 patients with ARP from Jan. 2003 to Dec. 2009 were reviewed retrospectively. Results Among 532 acute pancreatitis (AP) cases, 68 were diagnosed as ARP ( 12.8% ). The majority of ARP patients were male, amounting 76.5% of the total. The average age of ARP patients was 45.6 years. Cholelithiasis, hyperlipemia and alcohol were the most frequent factors causing ARP. Among the 68 ARP cases, 58 cases were mild (85.3%) and 10 cases were severe ( 14. 7% ). 54 cases underwent surgery or endoscopic treatment (79.4%) while 14 cases underwent non-operative treatment (20.6%). As a result, 66 cases were cured or improved and 2 cases with severe ARP died. Conclusion The key to reduce recurrent rate of ARP is to find out the causes of recurrence and then treat the diseases accordingly.
ABSTRACT
Objective To explore and analyse the causes of reoperation after biliary duct operation, so as to decrease the reoperation rate of biliary tract. Methods Clinical data of 71 patients who underwent reoperation of biliary duct diseases in our hospital between January 2005 to September 2010 were analysed,and the causes of biliary duct reoperation were summarized and analysed. Results The main cause of reoperation was recurrent or retained bile stone (76.1%,54/71), noncalculous stenosis of biliary tract ( 15.5 %, 11/71 ),biliary tract obstruction due to tumor (4.2%,3/71), and other factors (4.2%,3/71).Conclusion Recurrent or retained bile duct stone were the main cause for biliary reoperation, but noncalculous stenosis of biliary tract and biliary tract obstruction due to tumor could not be ignored. The initial rational operative method, approporiate operation time and the thoroughness of operation are the key factors to decrease bile duct reoperations.
ABSTRACT
Objective To explore the diagnosis and treatment of acute biliary pancreatitis (ABP) and when to operate. Methods 126 cases of ABP from Jan. 2005 to Dec. 2009 in our hospital were analyzed retrospectively. Results The cases number of the mild non-obstructive type, mild obstructive type, severe non-obstructive type, and severe obstructive type was 54, 33, 15, 24 respectively. 43 patients underwent early operation, 80 patients underwent postponed operation and three patients died preoperatively as a consequence of fulminat severe pancreatitis. 117 cases ( 92.86% ) were cured and 9 cases ( 7. 14% ) with severe acute pancreatitis died. Conclusion ABP should be treated according to its type. The key to reduce the complications and increase the cure rate is to determine the proper operation time according to the condition of individual patient.
ABSTRACT
Objective To investigate the distribution of biliary bacteriology and their sensitivity to antibiotics in patients with biliary tract infection in Jinshan area in recent 3 years.Methods Bile specimens collected from 367 patients with cholelithiasis between June 2006 and June 2009 were cultured and tested for drug sensitivity to aerobic bacteria.The results were statistically analyzed.Results One hundred and fifty-six bacterial strains were found in 142 (38.7%) bile specimens including gram negative strains (97,62.2%),gram positive strains (51,32.7% ),and fungal strains (8,5.1%).Enterococcus (17.9%) was major pathogen and follwed by Escherichia coli (12.8%),staphylococcus (11.5%),Klebsiella pneumoniae (8.3%),Pseudomonas aeruginosa (7.7%).Whereas the mixed infection was found in 26 (18.3%) specimens.The positive rate of bacterial infection was 53.1% in patients over 60 years of age (X2=8.36,P<0.01 ) and 47.1% in patients with acute biliary infection(X2=4.68,P<0.05).The drug susceptibility revealed that gram negative strains had low resistance to Meropenem (7.5 %),and followed by Imipenem (8.8 %),Cefoperazone +Sulbactam (19.7%),Amikacin (21.9%) and Tazobactam+Piperacillin (TZP,25.3%),but they were highly resistant to Ampicillin,Quinolones and some third generation of Cephalosporins (>50% ).In gram positive strains,none was resistant to Vancomycin,11.3% to fosfomycin and 11.6% to chloromycetin.They were highly resistant to Penicillins,Ampicillin and Cefazollin (>40%).ConclusionsEnterococcus,Escherichia coli,Sstaphylococcus and Klebsiella pneumoniae are commonly seen pathogens in biliary tract infection in Jinshan area.Use of Sulperazone or TZP plus Amikacin and metronidazole is recommended.Imipenem and Vancomycins may be second choice in treatment of severe biliary infection and refractory infection.
ABSTRACT
Objective To explore the clinical characteristic and diagnosis and treatment of HLAP.Methods The clinical data of 38 patients with HLAP were reviewed retrospectively.Results 38 cases were diagnosed as HLAP(10.7%),that included 29 cases with mild acute panereatitis(76.3%) and 9 cases with severe acute panereatitis(23.7%).34 patients were treated by nonsurgical methods(89.5% ),4 by surgery(10.5%),As a result,36 cases were cured and 2 cases with severe acute pancreatitis died.Conclusions HLAP are common,and have particular clinical manifestations.Treatment for HLAP is mainly by nonoperative management.Reducing the blood triglyceride could quickly alleviate symptoms.Surgical treatment should be adopted according to the severity of panereatitis.
ABSTRACT
Objective To investigate the reasons for and preventing measures of iatrogenic traumatic pancreatitis after epigastric operations and ERCP.Methods The clinic data of 18 cases of iatrogenie traumatic pancreatitis treated in our hospital from January 1992 to December 2006 were retrospectively analyzed.Results The disease occurred 12 cases after operation and in 6 after ERCP.The iatrogenic traumatic pancreatitis after epigastric operations or ERCP mostly occurred in 1-4 d after the operation.Twelve patients underwent conservative therapy(66.7%)and 6 reoperation(33.3%).Sixteen patients were cured and 2 died of the multiple organ failure after reoperation.Conclusion This complication iS related to the operative skill and expertise.The preventing measures include suitable operative handling,proficiency in technique and drug lessening excretion of pancreatic juice.Conservative therapy is of the first choice unless there is a state of illness alteration.
