ICH GCP requires that all information of clinical trial should be recorded, processed, and stored in a way that allows the accurate reporting, interpretation and verification. A trial master file (TMF) contains all paper or electronic records/documentations related to a clinical trial. As a tool of the retrospective analysis, the TMF profile should be able to reproduce the full procedure of the trial completely. As a part of TMF profiles, both the accuracy and completeness of clinical data management documentation are important in data integrity. It is helpful to learn the workflow of clinical data management in different stage of a clinical trial, to understand which documents are essential, and why the documentation of clinical data management is important for data integrity. This paper elaborates how to perform the good documentation practice of clinical data management, and suggests that both the precise and efficient document management and regular quality control may ensure the high quality of clinical data documentation management on the basis of an intensive awareness of the overall process of clinical data management.

Objective To investigate the clinic effect of trans-artery intrahepatic transplantation of porcine islet in type 1 diabetic patients. Methods Four patients with type 1 diabetes were perfused newborn porcine islets through the hepatic artery.Fasting blood glucose(FBS), postprandial blood glucose (PBS), HBA1,dose of insulin and function of liver and kidney were measured before and after the transplantation.Results The levels of FBS,PBS and HBA1 were 7 4～13 5mmol/L,7 8～18 6mmol/L and 7 8～12 0mmol/L respectively before the transplantation. During one and half years after transplantation, the levels of FBS,PBS and HBA1 were 3 3～7 1mmol/L,6 0～8 8mmol/L and 6 4～7 6mmol/L respectively with notably reduced dosage of insulin(32～58%).The function of liver and kidney of the patients remained normal.Conclusions Trans-artery intrahepatic transplantation of porcine islet is effective and safe for type 1diabetic treatment.

Objective To establish a method for determining the content of Naringin and Hesperidin in Zengshi Keli by HPLC.

The flow rate was 1.0 mL/min, the detective wavelength was 283 nm, the temperature of column is 35 ℃. Results The calibration curve were linear in the range of 0.178 5～0.892 5 ?g for Naringin and 0.073 68～0.368 4 ?g for Hesperidin (r=0.999 9) respectively. The average recovery was 97.24% (RSD=1.21%) and 96.95% (RSD=1.49%) respectively. Conclusion The method was simple, accurate, reproducible and can be used for quality control of Zengshi Keli.

Objective To study the distribution of rifampin(RFP), isoniazid(INH) and pyrazi-namide(PZA) in the focus of spinal tuberculosis in order to provide the regimen of chemotherapy and surgi-cal treatment of spinal tuberculosis. Methods Twenty-four patients with spinal tuberculosis were divided into sclerotic group or non-sclerotic group according to the radiographic features of lesion. All patients re-ceived chemotherapy with 2SHRZ/2.5 H2R2Z2 for a duration of 4.5 months. 4 weeks after chemotherapy, all patients underwent surgery and specimen of serum, ilium and vertebral tissues including sclerotic wall, sub-normal osseous tissue, focus inside sclerotic wall (sclerotic group) and destructive focus, peripheral subnor-mal osseous tissue (non-sclerotic group) were obtained during operation at 120-130 and 180-190 minutes after oral intake in the morning respectively. The levels of 3 drugs in the specimen were measured using HPLC method. Results 1) The concentration levels of INH and PZA in serum were similar to the data in the literature, but the level of RFP was only 75% of that in the literature. The levels of 3 drugs in osseous tissue were significantly less than those of blood. 2) Concentrations of isoniazid and rifampicin in self-control ilium and sub-normal bone tissue were within or exceeded the bactericidal concentration values,and pyrazi-namide was five fold of it's minimal inhibitory concentration (MIC) in acid cellular condition. There were no significant differences between sub-normal bone and self-control ilium of 3 drugs concentration. 3) Concen-tration of 3 drugs in sclerotic bone wall were approximate to MIC respectively in sclerotic group and much lower than sub-normal bone. There was no drug distribution of focus inside sclerotic bone wall. 4) RFP and PZA in focus of non-sclerotic group corresponded to the levels of MIC respectively, though much lower than in other parts of vertebral tissues, but the INH in focus was of bactericidal level. Conclusion The sclerotic bone of affected vertebra plays an important role to block the drug's penetration into tuberculosis focus.

Objective To study the diagnosis and therapy of Hashimoto's disease (HD) with thyroid nodule. Methods The clinical data of 187 patients with nodulous Hashimoto's disease who had operation in our hospital from 1995 to 2008 were analysed retrospectively. Results The nodules coexisting with Hashimoto's disease were thyroid carcinoma, nodular goiter, thyroid follicular adenoma and lymphoma accounting for 11.2% (21/187), 26.7% (50/187), 15% (28/187) and 1.6% (3/187) respectively. Conclusions HD patients with thyroid nodules especially the single nodule that can not be distinguished from cancer should have operation in time. Ultrasound guided needle aspiration will be helpful for the preoperative diagnosis and the frozen section may guide the surgical modality.

Objective To develop the cDNA microarray for the combined detection of hepatitis virus, and to study the feasibility of applying the microarray in clinical setting. Methods For the small and simple genome of HBV and HDV, the specific primers of PCR were designed with Primer Premier 5.0 program according to the conserved region of HBV and HDV, and 10 and 4 gene fragments were obtained respectively, which could be used as the probes of gene chip. As for the complex genome of HCV, the technique of restriction display PCR (RD-PCR) was employed. Some of gene fragments were selected which were comparatively more specific and sensitive as microarray probes. In order to explore the experimental conditions of microarray in vitro detection, three types of gene chip were prepared successively including HBV and HDV simultaneous detection, HCV detection and modified HCV detection. Results The hybridized signals on the gene chip showed that the effect in detection was satisfactory. Through the prepared gene chips mentioned above, some probes with good quality were selected and the microarray was prepared for HBV, HCV and HDV simultaneous detection. The diagnostic capability of the microarray was evaluated following the washing and scanning steps. Linearity: Serial dilutions of the target DNA or cDNA showed that a strong linear relationship existed between the various concentrations of target DNA or cDNA and the fluorescence intensities obtained from microarray assay (r=0.990 2, r=0.992 1, r=0.981 9), and that the detection range for the microarray was from 104 to 1011 copies/ml. Specificity: Samples from other viruses such as YFV, JET and DV were also subjected to the test and the results were all negative. Reproducibility: The reproducibility of this assay system was evaluated by repeated measurements, and the within-run coefficient of validation of HBV, HCV and HDV were 7.1%, 7.2% and 6.6%, respectively, while the between-run coefficient of validation was 7.9%, 8.2% and 7.6%, respectively. Accuracy: By using the BLAST and the GenBank database, the identity of the obtained sequences including 16 fragments of PCR, 24 RD fragments of HCV and some positive serum samples were verified, each sequenced product was confirmed to be a genome fragment of expected size. In order to fulfill the request of clinical diagnosis, a modified protocol for microarray detection was established. This new protocol consisted of two hours of hybridization, omitting the steps of prehybridization and purification of samples, and the hybridization temperature was elevated from 42℃ to 52℃, et al. The whole protocol could be completed in less than 8 hours. 98, 42 and 5 serum samples from hepatitis B, C and D patients and 130 samples from healthy people were analyzed, respectively, by microarray assay and real-time PCR (Taqmam method). There was a significant correlation between the results of these assays (HBV, r=0.985 4 and HCV, r=0.958 2, P

Objective To investigate the risk factors of creatine kinase (CK) elevation in chronic hepatitis B (CHB) patients and treatment outcomes for better management of such patients. Methods The CHB patients complicated with CK elevation who were treated during the period from June 2013 to June 2015 were reviewed retrospectively with their clinical data. CK elevation was examined in terms of antiretroviral regimens, and glycyrrhizin therapies. The clinical outcome was evaluated in terms of grade 3/4 CK elevation. Results A total of 364 CHB patients with CK elevation were included in this analysis. CK elevation was primarily associated with telbivudine monotherapy and combination therapy, followed by entecavir treatment. Grade 3/4 CK elevation was identified in 30 patients, which was mainly associated with telbivudine monotherapy and combination therapy. Good outcome was observed in most of these?patients?(76.7?%,?23/30).?Myopathy?was?confirmed?in?one?patient?by?muscle?biopsy.?Glycyrrhizin?was?not?associated?significantly?with CK elevation in CHB patients. Conclusions Creatine kinase elevation usually occurs in the CHB patients receiving telbivudine-containing therapies. CHB patients should be monitored for CK level during antiviral therapy. Concomitant glycyrrhizin treatment is not associated with CK elevation.

ObjectiveTo evaluate the neuroprotective effect of gradient perfusion-rewarming after deep hypothermia circulatory arrest (DHCA) in piglets.Methods12 Shanghai piglets (3-4 weeks old) were randomly divided into two groups of A (experiment group) and B (control group),average weight (9.78 ±0.93)kg.Animal CPB model is completed with microinvasive technique.DHCA duration is 90 min in two groups.During the rewarming period,group A was rewarmed with gradient perfusion strategy,maintain the temperature for 15 min every 5 ℃ elevation of the core temperature.Group B was rewarmed according normal consistent rewarming strategy.PH-stat management is adopt in both groups.Blood gas analysis,rectal temperature,heart rate,ECG,blood flow rate of carotid artery,glumatic acid/aspartate level of jugular vein and protein NFB of brain tissue are monitored during and/or after the cardiopulmonary bypass (CPB).ResultsDuration of rewarming in group A is (67.3 ± 7.8) min,and (41.8 ± 3.6)min in group B (P ＜ 0.05).Sample collected at the beginning of CPB,15 min of rewarming,30 min of rewarming and 45 min of rewarming show that there is no difference between the blood flow rate at 15 min of rewarming; difference are shown at the 30 min and 45 min of rewarming (P ＜ 0.5 ).High performance liquid chromatography ( HPLC ) analysis show the obvious difference of glumatic acid level of jugular vein at 30 min of rewarming and 45 min of rewarming ( P ＜ 0.5),this kind of difference of aspartate can only be seen at the 45 min of rewarming.Histologic evaluation shows gradient rewarming has a better effect on preservation of CA1 area neuron in hippocampus,however,Immunohistochemistry doesn't find the same effect.ConclusionControlled gradient perfusion-rewarming strategy can improve the neuroprotective effect during DHCA,keeping the balance of the blood flow,cerebral local temperature and brain metabolism might be the mechanism.
