The author tested 34 urine samples with 5s-23srRNA gene spacer RFLP analysis and compared PCR results with serodiagnosis results.8 pafients of urine are positive by PCR. 7 patients were infected by B. garinii, 1 patient by B afzelii. These genospecies infecting patients are identical with those infecting local vectors. The results showed that the accuracy of laboratory diagnosis oould be improved by simultaneously testing samples with PCR and serodiagnosis. The method of 5s-23srRNA gene spacer RFLP analysis will probably be used widely in studying the relationship of clinical manifestation and genospecies and in epidemiology investigations.

Objective:To determine the basic characteristics and clinical manifestations of hospitalized patients with psoriasis in Hunan, and to provide reasonable reference for the etiology and treatment of psoriasis.
Methods:Totally 190 patients with psoriasis from January 1, 2012 to December 31, 2012 treated in the Department of Dermatology, the Second Affiliated Hospital of Central South University were retrospectively analyzed. The data were analyzed by SPSS17.0.
Results:The ratio of male to female inpatient numbers was 3.13:1, aged was between 40 and 70 years. The most common subtype of psoriasis was psoriasis vulgaris (64.73%), followed by psoriatic erythroderma (18.42%). The distribution of the subtype of psoriasis did not differ by gender. Nineteen patients recalled clearly the cause of proriasis, 5 of which were caused by medicine, and 4 by drinking. Totally 96 cases accompanied with other diseases, 24.21%of which accompanied with cardiovascular system disease.
Conclusion:There is no season difference in the hospitalization of patients with psoriasis. there are more male than female inpatients. Treatment of psoriasis should consider clinical classification, drug adverse reactions, and individual factors for individual treatment.

·AIM: To investigate the effect of vitamin A on the conjunctival goblet cells of rat after corneal transplantation.·METHODS: Rat graft rejection models of corneal transplantation were established. SD rats were receptor and Wistar rats were donors. After corneal allografts were performed, 48 SD rats were randomly divided into three groups, 16 rats in each group. Group A was blank control group; group B was treated by oculotect gel (containing vitamin A); group C was treated by 1g/L dexamethasone eyedrops. Besides, group D was normal unoperated eyes.Slit-lamp microscope was employed to record and compare rejection index (RI) of corneal transplantation. Through HE,PAS staining of conjunctival histological sections and image analysis system, the number and morphology of conjunctival goblet cells were observed and analyzed between operation group and normal group.·RESULTS: The HE, PAS staining detection showed that the number of conjunctival goblet cells in oculotect gel group,1g/L dexamethasone eyedrops group and control group is lower than that in normal group after surgery (P<0.01). The number of conjunctival goblet cells in oculotect gel group and 1g/L dexamethasone eyedrops group is higher than that in control group (P<0.05). The number of conjunctival goblet cells in 1g/L dexamethasone eyedrops group is higher than that in oculotect gel group (P<0.05).·CONCLUSION: The results indicate that vitamin A may inhibit the decrease of conjunctival goblet cells after corneal allograft rejection in rats.

Objective To investigate the relationship between the expression ofα1-antichymot-rypsin (α1-ACT)in plasma and postoperative cognitive dysfunction(POCD).Methods The cognitive function of 64 patients undergoing operation under general anesthesia was evaluated by a battery of cognitive assessment instruments(BCAI)and the levels ofα1-ACT were measured at the time 1 d pre-operatively and 7 d and 3 months postoperatively.The patients were randomly divided into two groups:30 patients in ulinastatin group (group U)were injected with 10 000 U/kg ulinastatin,which was dissolved in 100 ml saline,within 20 min at the time of 30 minutes before induction;while control group (group C)were injected with the same volume saline.Results There was no significant differ-ence between the expression of α1-antichymotrypsin in patients with POCD and in control patients at the time before operation.Compared with control patients,the levels of α1-ACT in patients with POCD at the time of 7 d and 3 months postoperation were significantly higher (P <0.05).The levels of α1-ACT at 7 d postoperation were significantly higher than that preoperatively in both groups (P <0.05).The incidence of POCD in group U were significantly lower than that in group C,at the time of 7 d and 3 months after surgery (P <0.05).Conclusion POCD is associated with high expression of plasma α1-ACT.

This study is to report the preparation of complexes of Ad5 and anionic liposomes (AL-Ad5), the amplification of adenoviruses with enhanced green fluorescent protein (eGFP) reporter gene performed by HEK 293 cells, the adenoviral vectors purified by cesium chloride gradient centrifugation, and the titer of adenovirus determined by cytopathic effect (CPE) method, hexon capsid immunoassay and quantitative-PCR (Q-PCR), separately. The prescription and experiment conditions were optimized by central composite design (CCD). The complexes of Ad5 and AL-Ad5 were formulated by the calcium-induced phase change method. The morpholopy, particle size and zeta potential were detected by dynamic light scattering (DLS) and transmission electron microscopy (TEM), respectively. Additionally, the bicolourable fluoresce-labeled complexes (F(labeled)-AL-Ad5) were prepared and their intracellular location in MDCK cells was detected by confocal laser scanning microscopy (CLSM). The results indicate that the complexes of AL-Ad5 exhibited a uniform distribution with a particle size of 211 +/- 10 nm and a zeta potential of -41.2 +/- 2.2 mV. The result of CLSM demonstrates that the intracellular location of red fluoresce-labeled adenovirus was consistent with that of green fluoresce-labeled liposomes suggesting that the naked adenovirus was well encapsulated by the anionic liposomes in complexes of AL-Ad5.

This paper explored the multi-angle, comprehensive and systematic clinical prac-tice teaching system for international students. Six teaching methods were integrated: bedside teach-ing, standardized patients teaching, electronic patients clinic teaching, Chinese students one-to-one help foreign students, a variety of English clinic small presentation and many after-school social activi-ties. The multi-angle, comprehensive and systematic clinical practice teaching system was evidently a better choice than traditional teaching system for international students.
