Objective To discuss the relationship between prognosis and different surgical procedures for gallbladder cancer in different stages. Methods The clinical data of 107 patients with gallbladder cancer from January 2001 to May 2007 were retrospectively analyzed. The surgical procedure was chosen according to different stages. Results Eighty-one of the 107 patients (75.6%) were followed up with the median time of 5 years. Of the 10 patients with stage Ⅰ gallbladder cancer who had underwent simple cholecystectomy, 9 survived. Of the 8 patients with stage Ⅱ gallbladder cancer, 3 received palliative cholecystectomy and the median survival time was 12 months, which was significantly shorter than 24 months of the remaining 5 patients who received radical operation (X2= 5.698, P <0.05). Of the 42 patients with stage Ⅲ gallbladder cancer, 18 received radical operation, and the median survival time was 24 months, which was not significantly different from 18 months of the 5 patients who received extended radical operation (X2=0.238, P>0.05). The remaining 19 patients received palliative operation, and the median survival time was 6 months, which was significantly shorter than those of patients received radical operation or extended radical operation (X2=5.772, 6.318, P <0.05). There were 47 patients with stage Ⅳ gallbladder cancer. Seventeen patients received extended radical operation and 30 received palliative operation, and no significant difference upon the median survival time was observed among different surgical procedures (X2=0.001,0.694, P>0.05). The complication recurrence after the extended radical operation was significantly higher than palliative operation (X2=6.039, P<0.05). Conclusions For patients with stage Ⅰ gallbladder cancer, simple cholecystectomy is preferred. Radical operation is good for patients with stage Ⅱ gallbladder cancer. The choose of radical operation or extended radical operation for patients with stage Ⅲ gallbladder cancer should be based on the condition of invasion. Palliative operation could be used to patients with stage Ⅳ gallbladder cancer.

Objective To explore the effects of inducible co-stimulator (ICOS) gene on the cytotoxic activity of cytokine-induced killer (CIK) cells against cholangiocarcinoma cells. Methods CIK-ICOS cells were obtained by stable transfecting ICOS genes into CIK cells through the adenovirus vector whereas untransfected and EGFP-transfected CIK cells were treated as controls. The proliferation and apoptosis of different CIK cells, as well as their cytotoxicity against cholangiocarcinoma cells in the three groups were detected. The expressions of IFN-T, IL-2 and TNF-α in the supernatant of different CIK cells were measured by ELISA. SCID mice with cholangiocarcinoma were randomly divided into CIK group, CIK-EGFP group, CIK-ICOS group and normal saline group. The cytotoxic activity of CIK-ICOS cells against cholangiocarcinoma cells in vivo was observed. Results CIK-ICOS cells displayed better proliferation than CIK cells and CIK-EGFP cells. At day 20 and 23 of culture, the apoptosis rate of CIK-ICOS cells was 0.69% and 0.89%, respectively, while that of the CIK cells was 2.90% and 4.92%. The cytotoxic effect of CIK-ICOS cells at different E: T ratio against cholangiocarcinoma cells was significantly stronger than that of CIK cells and CIK-EGFP cells (F=13.37, 6.46, 25.51, P<0.05). The concentration of IFN-γ in CIK-ICOS cultured supernatant was (49.50±4.73)μg/L, which was significantly higher than that in the cultured supernatant of CIK cells [(30.53±3.73)μg/L] and CIK-EGFP cells [(30.12±2.64)μg/L](F=38.89, P<0.05). The growth of cholangiocarcinoma was significantly slower in CIK-ICOS group than that in CIK group and CIK-EGFP group, whereas the necrosis area of tumor was larger and the CIK cells in CIK-ICOS group was more than those in the other two groups. Conclusions CIK cells had the function of killing cholangiocarcinoma cells in vitro and in vivo. After ICOS genes were transfected into CIK cells, the survival time of CIK cells in vitro was prolonged and the proliferation of CIK cells was enhanced, as well as the secretion of IFN-γ was increased so that the cytotoxicity of CIK cells against cholangiocarcinoma cells in vitro and in vivo was enhanced.

Objective To evaluate the feasibility of simultaneous endoscopic bilateral placement of self-expandable metal biliary stents. Methods A total of 9 patients with hilar malignancy of Bismuth type Ⅱ to Ⅳ were enrolled in the current study, with a mean serum bilirubin at 162. 8 ± 193. 8 μmol/L before the procedure. Two guide wires were selectively inserted into the left and right intrahepatic ducts and kept in site. After aggressive dilatation for beth sides, the metal stents were deployed one by one bilaterally. Success rate of the procedure, remission of jaundice, early complications, and short-term clinical outcome were ob-served. Results The procedure was succeeded in all patients with Y type stent in 2, plastic stent transition in 1 and parallel stenting in 6, which took an average time of 38. 1 min. The most convenient way was the parallel method with both distal ends of the stents remaining at outside of papilla. The serum bilirubin re-turned to normal level within 3 weeks in all patients except 1, and no major complications were observed. Conclusion Simultaneous endoscopic bilateral metal stent placement is technically feasible and safe, with the benefit of prompt and effective control of jaundice and infection, caused by hilar tumors. A better method is to place specially designed endoprotheses in parallel and leave the distal ends outside papilla.

Objective: To explore the relationship between the time of sedentary behaviors and the risk of type 2 diabetes mellitus (T2DM) among rural adults in Henan Province. Methods: A total of 1 227 adults from Houzhai village in Zhengzhou City and Qiaomiao village in Jiaozuo City in Henan Province were randomly selected to participate in the survey; each of them finished a questionnaire and accepted physical examination and test of biochemical indicators. The participants were divided into case and control groups according to whether suffering from T2DM. A Pearson linear correlation and linear regression model analysis were used to investigate the relevance between the time of sedentary behaviors and fasting plasma glucose (FPG); meanwhile, a multi factor logistic regression model was used to analyze the relationship between the time of sedentary behaviors and T2DM. Results: The average FPG level among the participants was (5.4±2.5) mmol/L, and the average time of sedentary behaviors was (234.5±156.5) min per day. The prevalence rate of T2DM in subgroups whose time of sedentary behaviors were separately 0-<2.5, 2.5-<4.5, 4.5-<6.5 and ≥6.5 h/day were 15.8% (72/457), 19.3% (73/379), 16.7% (35/210) and 20.4% (37/181), respectively. There was a linear regression relationship between the time of sedentary behaviors(x) and FPG(y), the regression equation was: y=5.081+0.001x (t=3.01, P=0.003). Logistic regression model analysis showed that participants whose time of sedentary behaviors ≥6.5 h/day had significantly higher risk of T2DM than those whose time of sedentary behaviors between 0-2.4 h/day (OR=1.77, 95%CI: 1.11-2.81) after age and gender adjusted. However, the associations only exist in males and adults ≥50 years old according to sex and age stratification. It showed that participants with sedentary time ≥6.5 h/day had significantly higher risk of T2DM than those with sedentary time between 0-<2.5 h/d, with the corresponding OR (95%CI) at 2.34 (1.21-4.52) and 2.22 (1.19-4.16), respectively. Conclusion The prolonged sedentary time is a risk factor of type 2 diabetes. After stratification by gender and age, the correlation only found in males and adults aged ≥50 years old.

Objective To study the effects of pressure controlled ventilation(PCV)and volume controlled ventilation(VCV)on diaphragm function and the incidence of postoperative pulmonary complica-tions(PPCs)in patients undergoing laparoscopic surgery.Methods Sixty-six patients underwent laparo-scopic gynecological surgery under general anesthesia,aged 18-64 years,BMI 18-30 kg/m2,ASA physical status Ⅰ or Ⅱ were recruited.The patients were randomly divided into two groups:PCV group(group P)and VCV group(group V),33 cases in each group.All the patients were ventilated in VCV mode after induction.Group P was switched to PCV after pneumoperitoneum and group V maintained VCV until the end of operation after pneumoperitoneum.The diaphragm ultrasonic evaluation indexes including di-aphragmatic excursion(DE),diaphragm contraction velocity(DCV),and diaphragmatic rapid shallow breathing index(D-RSBI)were recorded before anesthesia induction,immediately after extubation,and 30 minutes after extubation.The mechanical ventilation time,artificial pneumoperitoneum time,the time from the end of artificial pneumoperitoneum to extubation,the cumulative dosage of cisatracuriumbesylate,and the patient's observer's assessment alert/sedation(OAA/S)immediately after extubation,the incidence of diaphragm dysfunction immediately after extubation and 30 minutes after extubation,and the cumulative in-cidence of PPCs in 1-3 days after operation.Results Compared with group V,DE in group P was in-creased significantly immediately after extubation(P＜0.05),but there was no significant difference in DE of 30 minutes between the two groups after extubation.Compared with group V,DCV in group P was in-creased significantly immediately after extubation and 30 minutes after extubation(P＜0.05),the inci-dence of PPCs in group P was significantly lower on the 1st day after operation(P＜0.05).There were no significant differences in D-RSBI,time of mechanical ventilation,time of artificial pneumoperitoneum,time from the end of pneumoperitoneum to extubation,cumulative dosage of atracurium besylate,OAA/S score immediately after extubation,and the incidence of diaphragm dysfunction immediately after extubation and 30 minutes after extubation,and the cumulative incidence of PPCs on the 2nd and 3rd day after operation.Conclusion In lower abdominal endoscopic gynecological surgery,compared with volume-controlled venti-lation mode,pressure-controlled ventilation mode dose not reduce the incidence of postoperative diaphragm dysfunction,but dose alleviate the weakening of diaphragm inspiratory force and reduce the incidence of pul-monary complications on the first day after operation.

Objective To investigate the efficacy of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) in the treatment of refractory septic shock in children.Methods From January 2016 to December 2018,the clinical data of children with refractory septic shock (RSS) treated by VA-ECMO in Department of Critical Medicine Affiliated Children's Hospital of Shanghai Jiao Tong University were retrospectively analyzed.The patients with refractory septic shock (RSS) treated by VA-ECMO were compared with those with non-refractory septic shock (NRSS).Results There were 8 cases in the RSS-ECMO group and 6 cases in the NRSS-ECMO group.The sex,age,PRISM score,complication showed no significant difference in the two groups.The median time of ECMO in the RSS-ECMO group was 182 (141,216) h,and 5 patients were survived and were discharged from the hospital.The blood lactic acid and vasoactive drug index in the RSS-ECMO group was significantly higher than that in the NRSS-ECMO group (P＜0.05 or P＜0.01).The time of vasoactive drugs use and the ratio of combined continuous renal replacement therapy (CRRT) in the RSS-ECMO group were higher than those in the NRSS-ECMO group,but there was no significant difference (P ＞ 0.05).Atter ECMO establishment,the mean invasive arterial pressure increased significantly at 6 h,and lactic acid decreased significantly at 12 h after ECMO support.SCVO2 returned to normal at 24-h ECMO therapy.Conclusions The success rate of VA-ECMO treatment in children with refractory septic shock complicated with MODS is similar to that of children with non-refractory septic shock.The relationship between ECMO and hemodynamic indexes in sepsis should be further explored.

Objective: To investigate the incidence and clinical features to probe the risk factors of hemorrhagic cystitis (HC) in children and adolescents with hematological diseases post haplo-hematopoietic stem cell transplantation (haplo-HSCT) . Methods: Medical records of 62 children and 27 adolescents with hematological diseases treated with haplo-HSCT between 2015 and 2016 were analyzed. Results: Of 89 cases (56 boys and 33 girls) , 44 patients were diagnosed with ALL, 33 AML, 3 AHL and 9 MDS. HC occurred in 32 of the 89 patients with an incidence of 36%, including 6 with grade Ⅰ, 16 with grade Ⅱ, 8 with grade Ⅲ, 2 with grade Ⅳ HC, respectively. The median time of HC onset was 25 days (range 2-55 days) after haplo-HSCT with the median duration as 19 days (range 3-95 days) , all of them were cured. The incidence of HC was lower in the group of children than that in the group of adolescents (27.4% vs 55.6%, χ²=6.466, P<0.05) , and the incidence of HC was higher in the group of patients who were ≥5 years old than that in the group of patients who were <5 years old (0 vs 34%, χ²=4.043, P<0.05) . Conclusion HC is one of common complications in children and adolescents with hematological diseases post haplo-HSCT, older age was associated with increased mortality.

Objective:To investigate the tendency of bacterial distribution and drug resistance of clinically isolated pathogens in the pediatric intensive care unit (PICU), which provided references for the reasonable application of antibiotics.Methods:The distribution characteristics of all clinical isolates from PICU of Children′s Hospital of Shanghai Jiaotong University from January 2010 to December 2018 and their trend of drug resistance were retrospectively analyzed.Results:A total of 2 749 strains of bacteria were isolated, including 1 912 strains (69.6%) Gram-negative bacteria and 837 strains (30.4%) Gram-positive bacteria.The top 6 detected bacteria were Acinetobacter baumannii (749 stains, 27.2%), Klebsiella pneumoniae (289 stains, 10.5%), Staphylococcus aureus (214 stains, 7.8%), Stenotrophomonas maltophilia (207 stains, 7.5%), Escherichia coli (204 stains, 7.4%) and Pseudomonas aeruginosa (189 stains, 6.9%). Among them, the detective rate of Maltophilia Stenotrophomonasannually increased from 6 strains (2.8%) in 2010 to 39 strains (9.5%) in 2018.The resistance rates of Acinetobacter baumannii and Klebsiella pneumoniae to carbapenems increased year by year, which was up to 96.0% and 71.4% to Meropenem by 2018.Their resistance rates to the third-generation cephalosporins, aminoglycosides and sulfonamides were higher than 70.0%.The sensitivity rate to Tigecycline and Polymyxin was 100.0%.The detection rate of Methicillin-resistant Staphylococcus aureus (MRSA) significantly increased from 18.2% in 2010 to 50.0% in 2018 ( χ2=19.38, P=0.013). No Vancomycin-resistant strains were found. Conclusions:Gram-negative bacteria are the main clinical isolates of PICU.Acinetobacter baumannii, Klebsiella pneumoniae, and especially Pseudomonas maltophilus, have a significant growth trend in the detection rate. Acinetobacter baumannii and Klebsiella pneumoniae are highly resistant to carbapenems.MRSA annually grows, but it still maintains a high degree of sensitivity to Vancomycin.

The interleukin (IL) -23/IL-17 axis is the main pathway in the pathogenesis of plaque-type psoriasis vulgaris, and IL-17A plays a key role in the relevant immune pathways. IL-17A mediates overlapping inflammatory pathways in atherosclerosis and psoriasis, promotes inflammation, coagulation and thrombosis, and plays an important role in the occurrence and development of cardiovascular comorbidities in patients with psoriasis. Inhibiting the inflammatory effect of IL-17A can reduce the incidence and mortality of cardiovascular comorbidities in patients with severe psoriasis. This review summarizes recent research progress in IL-17A-mediated systemic inflammation and cardiovascular comorbidities in patients with psoriasis, and provides a reference for prevention and reduction of cardiovascular comorbidities in patients with psoriasis in clinical practice.

Objective:To analyze clinical characteristics of neurosyphilis patients with abnormal mental behaviors as the initial symptom, and to provide a reference for clinical classification of, as well as outcome prediction and efficacy monitoring in neurosyphilis.Methods:Clinical data were collected from 67 HIV-negative neurosyphilis patients with abnormal mental behaviors as the initial symptom in the Second Affiliated Hospital of Soochow University from November 2012 to November 2019, and retrospectively analyzed. Statistical analysis was carried out by using t test. Results:Among the 67 patients, 52 (77.6%) were males, and 15 (22.4%) were females; there were 63 (94.0%) middle-aged and elderly patients and 4 (6.0%) adolescent patients; 38 (56.7%) patients were diagnosed with progressive general paresis, 21 (31.3%) with meningovascular neurosyphilis, 1 (1.5%) with meningeal neurosyphilis, 3 (4.5%) with tabes dorsalis, and 4 (6.0%) with mixed-type neurosyphilis. As laboratory examination showed, 67 patients all presented with positive serum rapid plasma reagin (RPR) test, serum Treponema pallidum particle agglutination (TPPA) test, and cerebrospinal fluid TPPA test, 55 (82.1%) had positive cerebrospinal fluid RPR test, 47 (70.1%) had elevated cerebrospinal fluid protein levels of > 0.45 g/L, 50 (74.6%) had increased white blood cell counts of > 8 ×10 6/L in cerebrospinal fluids, and 28 (41.8%) had elevated IgG levels in cerebrospinal fluids. Magnetic resonance imaging of the brain revealed multiple ischemic foci in 21 (31.3%) cases, multiple leukodystrophy in 17 (25.4%) , cerebral atrophy in 15 (22.4%) , infarction in 8 (11.9%) , and encephalitis-like changes in 2 (3.0%) . Of the 67 patients, 48 were treated with penicillin in aqueous solutions, 15 with ceftriaxone, and 4 with doxycycline. Six months later, the follow-up showed that 46 (68.7%) patients responded to the treatment, and the early course of disease was significantly shorter in the highly responsive group than in the poorly responsive group ( P < 0.05) . Conclusion:The middle-aged and elderly males were predominant in the neurosyphilis patients with abnormal mental behaviors as the initial symptom, magnetic resonance imaging is helpful for clinical classification and prognosis prediction of neurosyphilis, and early and standardized antisyphilitic treatment can markedly improve the prognosis of patients.
