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.

·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 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.

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.

Objective To search for the reasons of high positive rate of amotile bacteria and the diagnosis of septicemia in new-born Methods The blood was drawn from the different site of the new-born with septicemia and carricd out blood culture. The drug sensitivity test had been done by the method of paper stripdiffusion. The plasmids of bacteria were extracted rapidly by medified Birnboim method and the plasmid analyss was carried out. The plasmids's DNA of 35 epidemic strain was cut off by both restriction enzyme of Hind Ⅲ and EcoR Ⅰ. The outer membrane protein (OMP) was determined by SDS-polyacrylamide gel electrophoresis.Results There are 51 patients with positive blood culture amotile bacterium,of them, pollution; 35 cases (68．6%), septicemia: only 16 cases (31．4%),54．8% (57/104) strains bacteria have drug resistance to more of 12 drugs. 87．3% (165/189) strains bacteria have plasmids. They are cut off as 6 DNA fragments (1．9,2,4,5, 8．5 and 18Kb) by Hind Ⅲ restrietion enzyme. and as 5 DNA fragments (2,2．6,3．2, 6．3 and 22 Kb) by EcoR Ⅰrestrietion enzyme, it is showed that they come from a same clone. The epidemic strain include 10 slips OMP, but non-epidemic strain have 11 slip OMP, increase a 25Kd belt. The amotile bacteria with above-mentioned plasmid spectrum, restriction enzyme spectrum and OMP spectrum are only seen in the air, therapeutic dish and syringe needle.Conclusion The pollution is an important reason of amotile bactorium high positiye rate in new-born.Diagnosing septicemia should depend on bacteria culture, plasmid analysis restriction enzyme analysis of plasmid DNA, oMP determination and combining medical history and clinical manifestation.

As an essential amino acid, tryptophan (Trp) has various physiological functions and is of great significance in the metabolic process of tumors. In the human body, tryptophan is mainly transformed through kynurenine metabolic pathway, which not only promotes the inherent malignant properties of tumor cells, but also leads to immune-suppressive tumor microenvironment. Changes in tryptophan metabolism often occur in tumors, accompanied by abnormal gene expression of tryptophan-related enzymes, among which indoleamine 2,3-bioxygenase (IDO)-related gene expression and tryptophan 2,3-dioxygenase (TDO)-related gene changes are the most significant. A large number of clinical trials on IDO inhibitors, TDO inhibitors and combination therapy have been carried out. This paper reviewed the tryptophan metabolic pathway, regulation of IDO (TDO), kynurenine (KYN) and other related genes in tumor cells, and outlined the development of therapeutic schedule targeting tryptophan-related genes. The new progress provides new ideas for the further exploration of tumor treatment options.
