Objective:Cholangioduodenal reflux is still an unresolved problem in interposed jejunal choledochoduodenostomy (IJC) yet.To settle this problem,we designed IJC with distal suspending (IJCDS).Methods:IJCDS is to insert and suspend the distal end of the 25 cm-ling interposed jejunum to the duodenal cavity,which is about 2.5 cm long.The pressure of the biliary tract and the biochemical composition or the bile were measured during and after the operation and the results were compared.Barium meal and cholangiography through T tube were performed after the operation.Follow-up surveys were also done.Results:The pressure or the biliary tract decreased distinctively after the operation.Barium meals found no cholangioduodenal reflux although the patients had changed many postures.Cholangiography through T tube showed parisaltic or the interposed jejunum and the contrast medium was continuously pushed into the duodenum.Noreflux cholangitis and stone recurrence were found in the follow-up survey in 14 patients.Conclusion:IJCDS has the powerful function on preventing cholangioduodenal reflux.On the other hand,it avods the shortcomings of other reflux-preventing operative pattern.So it had the good prospect to extend its clinical usage.

In order to improve the production of agro-antibiotic 2-16,the producing strain(Streptomyces ahygroscopicus var.huangshanensis) was treated by protoplast regeneration,ultraviolet radiation,NTG mutagenesis and low energy C~(+) ion implantation.At last,a high-yield strain No.515 was obtained.The production of ~()No.515 was increased by 223.10%.By using Plackett-Burman design and Response Surface Analysis provided by SAS software,the cultivation condition of No.515 was optimized.The amount of agro-antibiotic 2-16 was increased by 38.53% when the strain No.515 was cultivated in the optimum medium instead of the initial one.

A retrospective review of 47 patients underwent closed mitral commissurotomy(CMC) was conducted. It was revealed that the post-operative color echocardiography indices (MVA ,MVG,CO) were significantly improved compared with those of pre-operation (P8 had NYHA class Ⅰ-Ⅱ in 5 years(P

Objective To investigate the causes, diagnosis and treatment of gastrolienal portal hypertension. Methods During recent 10 years, 32 cases of gastrolienal portal hypertension were admitted. Clinicopathological features were analyzed. Results The main causes of this entity was chronic pancreatitis or pseudocyst of the pancreas (14 cases), tuberculosis of lymph nodes in retroperitoneum (7 cases) , retroperitoneal malignant lymphoma (3 cases) and pancreatic tumors (8 cases). Definite diagnosis was made in all 32 cases during the hospitalization. Twenty cases underwent surgery including splenectomy (11 cases) , splenectomy plus portal-azygous disconnection (5 cases) , splenectomy plus distal pancreatectomy (4 cases) , endoscopic varicose vein ligation combined with partial splenic embolization (2 cases), and endoscopic varicose vein ligation ( 5 cases). Conclusion A definite diagnosis of gastrolienal portal hypertension lies in the surgeon's recognition of this entity. Splenectomy is the most effective symptomatic treatment.

Objective To investigate the application of pediatric early warning score (PEWS) in neurology department.Methods The clinical data and PEWS of 1,158 children with neurologic diseases (764 febrile seizures,259 viral encephalitis and 135 bacterial meningitis) admitted into neurology department from August 2013 to November 2016 were analyzed retrospectively.PEWS was compared among the three different diseases.According to the disease severity,cases were categorized into no-monitor-required group (n =996,697 febrile seizures,203 viral encephalitis and 96 bacterial meningitis),monitor-required group (n =138,67 febrile seizures,41 viral encephalitis and 30 bacterial meningitis) and PICU group (n =24,0 febrile seizures,15 viral encephalitis and 9 bacterial meningitis).PEWS was assessed at admission in both no-monitor-required group and monitorrequired group.PEWS was recorded 12 hours before PICU transfer in PICU group.Then PEWS was compared among all groups in different diseases respectively.Results The median (minimum ～ maximum) of PEWS in febrile seizures,viral encephalitis and bacterial meningitis was 0 (0 ～ 3),2(0 ～ 8) and 2(0 ～ 8),respectively and there was significant difference among three diseases (P ＜ 0.01).No patient of febrile seizures was transferred to PICU.PEWS of febrile seizures in monitor-required group was higher than that in no-monitor-required group (P ＜ 0.01).For both viral encephalitis and bacterial meningitis,PEWS in monitor-required group was higher than that in no-monitorrequired group,and the score in PICU group was higher than that in monitor-required group.The difference was significant (P ＜ 0.01).Conclusion PEWS is effective for the assessment of illness severity of hospitalized children in neurology department,and can be used for the prediction PICU transfer as an excellent screening tool.

Objective To evaluate interleukin-27 ( IL-27 ) as a sepsis diagnostic biomarker in critically ill adults with sepsis. Methods A retrospetive study was conducted. A total of 176 systemic inflammatory response syndrome ( SIRS ) patients in Department of Critical Care Medicine of Xinxiang Medical College First Affiliated Hospital from March to November in 2014 were enrolled. The patients were divided into no sepsis group ( n=66 ), pulmonary originated sepsis group ( n=65 ), and non-pulmonary originated sepsis group ( n=45 ). Plasma IL-27 and procalcitonin ( PCT ) were determined with enzyme linked immunosorbent assay ( ELISA ). Receiver operating characteristic curve ( ROC ) and classification and regression tree methodology was used to evaluate diagnostic biomarker performance. Results The proportion of patients in pulmonary original sepsis group whose body temperature in line with SIRS criteria was significantly higher than no sepsis group ( 66.2%vs. 44.5%, P<0.05 ), and they were easy to suffer from tumor ( 44.6%vs. 22.7%, P<0.05 ). The proportion of patients in non-pulmonary originated sepsis group whose white blood cell count in line with SIRS criteria was significantly higher than no sepsis group ( 68.9%vs. 42.7%, P<0.05 ). It indicated that patients in pulmonary originated sepsis group and non-pulmonary originated sepsis group were more in line with SIRS criteria compared with no sepsis group. It was shown by ROC curve that IL-27 and PCT was not effective in discriminating sepsis among unselected patients showing symptoms and signs of SIRS. The area under the curve ( AUC ) was 0.59 [ 95%confidence interval ( 95%CI )=0.49-0.65 ] and 0.61 ( 95%CI=0.55-0.71 ). According to the further analysis from different infection sources, the highest AUC was 0.71 ( 95%CI=0.59-0.79 ) for IL-27 in patients with a non-pulmonary originated sepsis. A decision tree incorporating IL-27, PCT, and age had an AUC of 0.78 ( 95%CI = 0.71-0.87 ) in patients with a non-pulmonary originated sepsis, which was higher than IL-27 [ 0.71 ( 95%CI = 0.59-0.79 ) ] or PCT [ 0.65 ( 95%CI = 0.57-0.78 ) ]. Compared to that of pediatric cohort with sepsis, lower expression of IL-27 was found in adult patients. Conclusions IL-27 performed overall poorly as a sepsis diagnostic biomarker in adults. IL-27 may be a more reliable diagnostic biomarker for sepsis in children than in adults. The combination of IL-27 and PCT can reasonably estimate the risk of sepsis in subjects with a non-pulmonary originated sepsis.

Objective To explore the lymphcyte subsets distribution in cerebrospinal fluid in patients with HIV infection ,and to investigate the clinical significance of the lymphocyte subsets in cerebrospinal fluid in HIV central nervous system complication . Methods 34 patients with HIV infection ,including 20 patients without nervous system symptoms (simple HIV group) and 14 pa‐tients with nervous system symptoms (neurological HIV group) ,and 15 cases of healthy people (control group) were selected .
