Objective To investigate the relationship between transfusion transmitted virus (TTV)infection and neonatal hyperbilirubinemia,the effect of TTV infection on the liver function, and analyse the feature of nucleotide sequences in TTV ORF1.Methods Serum TTV DNA,which were from 58 neonates with high direct bilirubin(DB,including 5 with hepatitis Syndrome),92 ones with high indirect bilirubin(IB),and 85 normal ones,was detected using a nested polymerase chain reaction technique(nPCR),electropherosis and sequence analyse,and serum alanine amniotransferase (ALT)was determined in all neonates.Results In DB neonates,TTV DNA were detected in 7 neo- nates(12.1%,including 3 neonates with hepatitis syndrome);in IB and normal ones,1 neonate had positive TTV DNA(1.1% and 1.25),respectively.Even if there were point mutations in Guangdong's TTV,the homology of Guangdong's TTV(GD1-9)and Japanese TTV(N22)ranged from 87.1%～97.8% at nucleotide level.Conclusion TTV infection may be one of important pathogenesis resulting in neonatal hyperbilirubinemia and liver damage in such patients.Guangdong's and Japanese TTV isolates had the same genotype,some gene mutations maybe increase the pathogenicity in TTV.

Post-operative recurrence and metastasis remain the leading causes of death for patients with gastric cancer. The major determinants of recurrence and metastasis are the biological characteristics of cancer cells and the immunological status of the patients. In recent years, due to the target-specificity, biotherapy has yielded efficacious responses in diverse clinical applications for cancer treatment, partially for the treatment of recurrence and metastasis of gastric cancer. However, because of the high diversities in clinical manifestations, patients' condition, and tumor's characteristics, there is no ideal strategy of biotherapy established for the prevention and treatment of recurrence and metastasis in gastric cancer. Therefore, a lot of work need to be done in basic research and clinical trial to make the biotherapy effective in treatment of gastric cancer recurrence.

AIM: To investigate the effect of PEDF on retinal neovascularization in mice. METHODS: 40 7-day-old C57BL/6J mice was exposed to 750mL/L oxygen for 5 days and then to normal situation to produce the murine model of oxygen-induced retinopathy(OIR). One eye of the mouse was regarded as experimental one and the other served as control. Eyes in experimental group received intravitreal injection of PEDF and eyes in control group received intravitreal injection of PBS at postnatal day 12. All mice were executed at postnatal day 17. The changes of retinal vessels of mice were observed by ADPase histochemical technique. The inhibitory effect of PEDF on retinal neovascularization was evaluated by counting the endotheliocyte nuclei of new vessels which extended from retina to vitreous in the tissue slice of HE staining. RESULTS: Neovascularization was reduced, retinal blood vessels distributed regularly and non-perfusion areas were not found in eyes of experimental group compared with control group. The number of endotheliocyte nuclei of new vessels extending from retina to vitreous was significantly less in the eyes of experimental group (10.18±1.74) than that in control group (38.89±2.98) (P<0.01). Retinal toxicity and inflammatory reactions were not found in tissue slice.CONCLUSION: PEDF inhibits retinal angiogenesis in OIR and the feasibility should be determined for use of PEDF in ocular angiogenesis treatment.

Objective To investigate the correlation between tetramine poisoning and hypocalcemia in children.Methods According to different severe cases grade,tetramine poisoning children were divided into critical group(70-90 score),extremely critical group(

Objective To observe the dose-effect relationship and side effects caused by epidural ketamine for patients after surgical intervention for knee stiffness (SIKS). Methods 80 patients undergoing SIKS at one knee joint under combined spinal and epidural anesthesia were randomly divided into 4 groups. Patients in these groups would receive analgesia respectively provided by femoral nerve block (FNB)(group C, n=20), FNB combined with 0.15 mg/kg epidural ketamine (group K1, n=20), FNB combined with 0.2 mg/kg epidural ketamine(group K2, n=20), and FNB combined with 0.25 mg/kg epidural ketamine (group K3, n=20). When spinal anesthesia was finished, the corresponding dose of ketamine was injected in patients in groups K1, K2, and K3 and 0.9% sodium chloride was injected in group C via an epidural catheter. After the operation, a catheter was left in the femoral nerve sheath and the solution of 60 mg ropivacaine in 30 ml (0.2%) was injected. All patients were performed rehabilitation therapy at postoperative 8, 24, 32, and 48 h and the same ropivacaine solution was injected in the femoral nerve sheath before each rehabilitation therapy started. Visual analogue score (VAS), active range of motion (AROM) of the suffered knee joint, and side effects were observed. Results There were 73 patients enrolled in the final statistic analysis. At postoperative 8 h, the VAS scores were lower in groups K1, K2 and K3 than in group C (P<0.05). At postoperative 24 h, 32 h, and 48 h, the VAS scores were lower in groups K2 and K3 than in groups C and K1 (P<0.05). AROM was larger in groups K2 and K3 than in groups C and K1. patients appeared psychiatric symptoms in group K3. Conclusion Small dose of epidural ketamine is a feasible method for analgesia in early rehabilitation therapy and the dose of 0.2 mg/kg is effective and safe.

Depending on the meaning and function of the liver in traditional Chinese medicine and modern medicine,this paper explores the important role of liver in the pathogenesis of DM (Diabetes Mellitus,DM).Combined with treatment based on syndrome differentiation and specific case report study,this paper has stressed the importance of treating DM from liver and so to set a sound basis for the systemic treatment based on syndrome differentiation from internal organs for DM.

This study was aimed to discuss the ways of converting clinical data entered in the Case Report Form (CRF) to Study Data Tabulation Model (SDTM) database format in clinical research of traditional Chinese medicine (TCM). Currently, there were three approaches for implementing SDTM, which were the pure SDTM approach, submission-only approach and database-only approach. This article compared and analyzed advantages and disadvantages of three approaches and introduced experiences of the Clinical Evaluation Center of China Academy of Chinese Medical Sciences using database-only approach for SDTM implementation. The results showed that pure SDTM approach can maximally embrace SDTM standards. However, the current process and software system should be modified. Therefore, it was time-consuming and expensive. The submission-only approach was the most economic way in the application of SDTM standards. However, the data quality and traceability may not be guaranteed. The database-only approach built the study database based on the SDTM standard by writing transformed program before data entry while the data collection system was not SDTM-compatible. It was concluded that database-only approach for implementation SDTM was a suitable and practical way to TCM clinical research.

In the cultural construction of independent institute,there exist the contradiction between tradition and innovation,cultural conflicts between private enterprises and the university.Therefore,adhering to the people-centered concept,coordinating tradition and innovation,merging the advantages of university culture and private enterprises culture into a whole,cultivating the unique spiritual culture,harmonious system culture and unified material culture of independent institute,forming the distinctive “Institute Culture” with its own cultural tradition will provide reference for the theory and practice to enrich and improve the connotative development of independent institute.
