Objective To determine whether pancreatic ductal preservation(pancreatic ductal injection of sparing TIUW solution at the time of pancreas procurement)can improve islet yield and function after cold preservation of pancreas.Methods Pancreases were classified into five groups:fresh pancreases(group1 ,n= 10);preserved for 6 hr in TIUW solution without and with pancreatic ductal preservation by TIUW solution(group2, n=10 and group3, n = 10);preserved for 24 hr in TIUW solution without and with pancreatic ductal preservation by TIUW solution(group4 ,n= 10 and group5,n= 10).Dithizon(DTZ)staining was used to identify islet morphous and yield, trypan blue uptake(TBU)was used to assess the nonviability of islets, the insulin secretory response to glucose was used to evaluate islet function in vitro, islet transplantation was used to determine islet function in vivo.Results Islet yields per pancreas after purification in group 1 to 5 were 590± 127, 272 ± 50,454 ± 65, 253± 56, 447 ± 66(islet equivalent ± SD), respectively.Percentage of nonviable islets in grouplto5were(5.7±4.2)%,(18.3±6.5)%,(11.7±4.2)%,(26.3±5.6)%,(15.0±5.3)%.Stimulation index in group 1 to 5 were 7.32±2.32, 4.81±1.17, 7.56±2.44, 2.88±1.00, 5.71±1.90.Cure rates in group 1 to 5 were 100%, 0%, 100%, 0%, 70%.In this study, the differences were significant between control groups and experimental groups(P＜0.05, group 2 vs.group3 and group4 vs.group5).Conclusion The pancreatic ductal preservation can improve islet yield and function.

Objective To conduct prospective randomized controlled clinical observation on patients with nasopharyngeal carcinoma under chemotherapy and radiotherapy using inhaling therapy with recombinant human interleukin 11,and the preventing and curing effect of recombinant human interleukin 11 on radiation-induced pharyngitis is evaluated.Methods 161 cases of newly diagnosed patients with head and neck cancer were selected under the principle of informed consent and these 161 cases were divided into the observation group (87 cases) and the control group (74 cases) based on randomization principle.In the observation group,when the dose reached 20Gy,then recombinant human interleukin-11 inhaling therapy was applied `ll the end of radiotherapy,for the control group,conventional treatment was applied in the event of radioactive throat.RTOG criteria were used during the observation in patients with the occurrence and treatment of radioactive pharyngitis.Results When compared with the control group,the average time for radioactivity to appear was prolonged,the severity decreased and the healing time was shortened in the observation group,those data were statistically significant.Conclusions Recombinant human interleukin-11 inhaling therapy can prevent and cure inhalation of radioactive pharyngitis and this therapy is better than conventional treatment.It's worthy of further study and clinical application.

Objective To investigate the clinicopathological features and treatment of children with C3 glomerulopathy (C3 G).Methods Seven children diagnosed as C3 G by clinical and pathological characteristics were enrolled in this study.The clinicopathological data and the prognosis were analyzed.Results Of the 7 cases,4 cases were female and 3 cases were male,with the mean age of (7.7-± 3.1) years old (1.5-10.4 years old) at onset,the duration from onset to renal biopsy was (3.4 ± 2.4) months (1-6 months) and 1 of them had a second renal biopsy 4.2 years later,and mean age was (8.4 ± 3.6) years old (1.8-13.3 years old) on diagnosis.Clinical features:among the 7 patients,6 cases had hematuria,among them 1 case had gross hematuria and 5 cases had microscopic hematuria;6 cases had low level of serum complement C3,5 cases had heavy proteinuria and low serum albumin,and anemia was observed in 2 cases respectively.Five cases had complement factor H and H factor antibody by examination,and 1 of them had low serum factor H,but none of them had serum antibody to factor H.Four cases had genetic evaluation,and only 1 case revealed risk variants in the C3 gene(R304R,T612T,V807V,A915A,P1632P)and CFH gene(p.H402Y,p.E936D).Clinically,4 cases were diagnosed as nephrotic syndrome of nephritis type,2 cases were diagnosed as nephritic syndrome,and 1 case was diagnosed as nephrotic syndrome of simple type.Immunofluorescence study showed that all the cases had intense deposition of C3,and 6 cases were accompanied by the deposition of immunoglobulin.Under light microscopy,3 cases showed the feature of membrane proliferative glomemlonephritis,2 cases with endocapillary prolifera-tive glomerulonephritis,1 case with mesangial proliferative glomerulonephritis,and 1 case with endoeapillary proliferative IgA nephropathy.Under electron microscopy,3 cases who had typical ribbon-like dense deposits in glomerular basement membrane were of dense deposit disease,and the rest were C3 glomerulonephritis.All patients had steroid and immune inhibitor treatment,and during the follow-up stage of (2.6 ± 1.8) years(1.1-5.6 years),4 cases showed normal urinalysis,2 cases had microproteinurine and microscopic hematuria,and 1 case had urinary protein ± to + + and microscopic hematuria.Conclusions C3G has variety of pathological-clinical manifestation.Interpretation of individual cases depends on integration of information from the biopsy together with clinical,serological,and genetic features.Patients with steroid and immune inhibitor treatment had some clinical improvement of their urinalysis.

Along with increasing use of inferior vena cava (IVC) filter implantation, more and more attention has been paid to the filter - related complications by scholars both at home and abroad. For the present the generally accepted filter- related complications include filter deformation, filter tilt, filter fracture, filter migration, IVC perforation, IVC thrombosis, IVC occlusion, recurrence of pulmonary embolism, deep vein thrombosis (DVT), post - thrombosis syndrome (PTS), etc. Accurate recognition of filter - related complications and prompt use of appropriate measures that are directed against a given complication in order to reduce or avoid complications are of great clinical significance in applying the inferior vena cava filter to clinical practice in a more safe and effective way. This paper aims to make a comprehensive review about the filter- related complications and the research progress concerning their prevention in recent years.

Objective To explore the clinic values of intraoperative fluid overload in evaluating the perioperative prognosis of patients after cardiopulmonary bypass cardiac operation. Methods A prospective observational study was conducted. The adult patients admitted to the Third People's Hospital of Chengdu from April 2014 to March 2016 for selective cardiopulmonary bypass cardiac operation monitored by pulmonary artery catheter or pulse-indicated continuous cardiac output (PiCCO) were selected. All patients received therapy with restrictive fluid management strategy after admission to the intensive care unit (ICU) and were divided into two groups based on the value of intraoperative fluid accumulation ratio at the time of admission to the ICU: group A with intraoperative fluid accumulation ratio of less than 10% and group B with equal to or more than 10%. Then the changes and different prognosis of the patients in groups were observed. Risk factors affecting the prognosis were analyzed using logistic regression, and the predictive values of various parameters on prognosis were analyzed using receiver operating characteristic curve (ROC). Results 224 cases were included, with 172 in group A and 52 in group B. No significant differences were found between both groups in gender, age, pre-operative scores by European system for cardiac operative risk evaluation (EuroScore), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA), operation ways, operation time, cardiopulmonary bypass time and blood loss (all P > 0.05). Both APACHE Ⅱ score and SOFA score in group B were significantly higher than those in group A at admission and 24, 48 and 72 hours after ICU admission (APACHE Ⅱ: 24.5±4.1 vs. 21.8±3.5, 14.8±6.5 vs. 9.9±3.9, 12.3±5.4 vs. 9.4±3.7, 10.9±5.0 vs. 8.9±3.3, SOFA: 12.3±2.9 vs. 10.6±2.1, 8.8±2.8 vs. 5.7±1.7, 7.2±3.0 vs. 5.0±2.0, 6.4±3.6 vs. 5.2±1.7, all P < 0.05). Compared with group A, incidence of combination with acute kidney injury (AKI) was significantly increased in group B (92.3% vs. 68.6%, P < 0.01), the level of post operation cardiac index (CI) was significantly lower in group B (mL·s-1·m-2: 40.67±4.00 vs. 49.84±7.50, P < 0.01). Both the duration of mechanical ventilation and the length of stay in the ICU in group B were significant longer than those in group A (days: 3.2±2.1 vs. 1.8±1.3, 5.0±1.7 vs. 3.6±1.2, both P < 0.01). The post-operation complications, 7-day and 28-day mortality in group B were all significantly higher than those in group A (65.4% vs 30.2%, 19.2% vs. 1.7%, 26.9% vs. 3.5%, all P < 0.01). Logistic regressive analysis showed that after controlling the influence of postoperative AKI and CI on mortality, the intraoperative fluid accumulation ratio at ICU admission was still an independent risk factor [odds ratio (OR) of 7-day mortality = 1.380, 95% confidence interval (95%CI) = 1.019-1.869, P = 0.037; OR of 28-day mortality = 1.302, 95%CI = 1.026-1.654, P = 0.030]. The area under the curve of ROC (AUC) in predicting the 28-day mortality of patients after operation using intraoperative fluid accumulation ratio was 0.874 (P = 0.000), with a sensitivity of 95.0 % and a specificity of 78.4% at the optimal threshold value of 7.5%. Conclusions Intraoperative fluid overload in patients admitted to the ICU would aggravate their condition, prolong the duration of mechanical ventilation and the length of ICU stay, and increase post-operative complications morbidity and mortality. After controlling the influence of AKI and cardiac insufficiency on mortality, the fluid overload was still an independent risk factor for the death of patients after cardiopulmonary bypass cardiac operation.

Objective To establish a method for data quality control of clinical research data based on electronic data capture (EDC) system.Methods After analyzed the specific characteristics of EDC's workflow process,and also referred to international data management guideline,we established the data quality control strategy by summarizing actual data quality control experience of data management department in Peking University Clinical Research Institute.Results Application of EDC has changed traditional clinical research process,therefore EDC data quality control strategy should be built according to its own process flow,namely,selecting the appropriate EDC system,reasonable design and build electronic case report form (eCRF),standardization research center / user management processes,timely and accurate on line eCRF filling up,accurately capturing/docking ex ternal electronic data,planned data monitor and auditing,timely and efficient query management,strictly data locking and unlocking operation process,and strict electronic record life cycle monitoring.Conclusions At present time,clinical research in China is still in the earlier stage of the transition from traditional paper-based data collection (PDC) to EDC.Establishing and applying particular quality control strategy will optimize the process and results of data quality control.

AIM: To compare the quality of Liuwei Dihuang Pill among the pharmaceutical companies by determining the content and the dissolution of paeonol of Liuwei Dihuang Pill. METHODS: A method of determining paeonol and the dissolution from Liuwei Dihuang Pill was establishod. HPLC was used with methanol-water (70 ∶30) as a mobile phase and detection wavelength was at 274 nm. The flow rate was 1.0 mLmin, injection volume was 20 ?L. The percentage of dissolution was determined in the 30% methanol- 0.1 mol1 HCL solution. RESULTS: A good linearity was over the weight range of 1.4 ?g-140 ?g, the average recovery was 97.38% , the RSD for reproducibility was 1.44% (n=6). The parameter of Tianjin’s production was T_ 50 = 156.77 , T_d= 256.55 ,M= 0.734 and the parameter of Beijing’s production was T_ 50 = 110.66 , T_d= 197.19 , M= 0.583 . CONCLUSION: The method is simple, and can be used to determine the content and the percentage of dissolution of paeonol in Liuwei Dihuang Pill. The experiment indicates that the percentage of dissolution has no obvious distinction in products from different manufactures; but has obvious distinction in the batches of same manufacture.

The third round of Global Fund AIDS Program carried out in the 19 counties of Henan Province has promoted a comprehensive prevention and treatment of AIDS in the whole province.The main achievement of this project includes about 23 698 medical staff training,improving the capacity of AIDS prevention and control in the areas,and attracting multidivisions to participate in the AIDS prevention and control work.As a result,1 092 government departments and grassroots organizations participated in the program and 2 832 activities,attracting 94 213 persons voluntarily to receive counseling and AIDS testing;the service of HIV Voluntary Counseling and Testing(VCT)has accounted for 99.33% of the total HIV detective samples.So VCT has become the major method of HIV detection in the population.The implementation of incentive mechanisms has promoted the intervention in high-risk behaviors,and has prevented AIDS transmission from mother to child or sexual transmission between couples.In 2008,the rate of mother to child transmission in Henan Province fell to 4.16 percent and the positive transforming rate of single-positive spouse was 1.13/100 person per year.Through the establishment of medicine supervision mechanisms to promote the anti-virus measures,the survival rate of the AIDS patients who have been treated for over 12 months has reached 89.48%.

0.05). Conclusion Though the noninvasive MRCP offers a diagnostic means equivalent to that of ERCP it is still too early to say it will take the place of ERCP.
