Twenty-four cases of juvenile pseudomyopia were corrected by puncturing Jingming (BL1)on the affected side, Hegu (LI 4) and Fengchi (GB 20) on the both side, and then moving both eyeballs in a rotary route. After 42 affected eyes were treated, 32 eyes were cured, 6 eyes were markedly effective, 2 eyes were improved, 2 eyes were ineffective and the total effective rate was 95.2%.

AIM: To evaluate the effects of interfer ?-2b (IFN ?-2b ) on atherosclerosis(AS).METHODS: Thirty normal male rabbits were randomly divided into five groups:normal control group(NC group, n= 6), atherosclerosis group(AS group, n =6),virus (herpesvirus Ⅰ,HSV-Ⅰ)infected atherosclerosis group(V group, n= 6), interferon (interferon ?-2b) intervented atherosclerosis group (IFN-Ⅰgroup, n= 6),interferon intervented and virus infected atherosclerosis group (IFN-Ⅱ group, n= 6). Serum lipids were measured and the thoracic aortas were sampled for histopathological, immunohistochemical and in situ hybridization study. RESULTS: The aorta atherosclerosis areas of NC, IFN-Ⅰ and IFN-Ⅱ groups were lower than that of AS group significantly, respectively, and the area of AS group was lower than that of V group ( P

Objective To construct eukaryotic expression plasmid pEE14.1-dsFv?pr+,and detect the expression of the recombined gene in eukaryotic CHO-K1 cells.Methods The cationic DNA fragment was cloned into the 3' of VH gene by overlapping extension PCR,and the 6?His tab was inserted to the 3' of VL and human IFN-? gene by the same way.The above mentioned recombinant VH and VL genes were inserted into a pCI-GPI vector first,and then cloned into the pEE14.1 vector to construct the recombinant plasmid pEE14.1-dsFv?pr+.Finally,the recombinant plasmid was transfected into the CHO-K1 cells by LipofectamineTM 2000,and the expression was detected by RT-PCR,ELISA and Western blotting.Results The enzyme digestion and sequencing analysis showed that the recombinant plasmid was successfully constructed.RT-PCR showed that only the cells with transfected plasmid can generate the specific 1700bp fragment.ELISA analysis showed that the production of IFN-?expressed in the supernatant of transfected cells was about 1.1ng/ml.Also,Western blotting could reveal the characteristic band of HBsAg dsFv?pr+ protein.Conclusion The antibody targeting to human IFN-?genes has been successfully expressed in a single open reading frame.Changing the electricity of the antibody may provide the necessary condition for the study of the a new type of anti-HBV drug in nanoscale in the future.

Objective To construct the prokaryotic expression plasmid of human prostate stem cell antigen (PSCA),to induce the expression of GST-PSCA fusion protein in E. coli BL21,and to identify the purified recombinant fusion protein. Methods The fragment of PSCA gene was amplified by PCR,and then cloned into the pGEM-T Easy vector. The transitional plasmid Teasy-PSCA was identified by DNA sequencing. The PSCA gene was digested from the plasmid Teasy-PSCA by restrictive enzyme BamH I and Sal I,and then inserted into the pET42a vector which contains a glutathione s-transterase (GST) tag. Following the double restriction enzyme digestion,the recombinant plasmid pET42a-PSCA was obtained and transformed into E. coli BL21 (DE3). The expression of GST-PSCA fusion protein was induced with IPTG. The recombinant fusion protein was purified by passing over a Glutathione Sepharose 4B column,and was identified by SDS-PAGE and Western blotting. Results The length of amplified PSCA gene fragment was consistent with that expected,and the sequence was correct as exemplified by the PSCA gene reported in GenBank. The result of enzyme digestion indicated that the prokaryotic expression plasmid pET42a-PSCA was successfully constructed. After transformation with pET42a-PSCA and induction with IPTG,the recombinant target protein of about 43kD was obtained. The GST-PSCA fusion protein was correctly identified by SDS-PAGE and Western blotting. Conclusions The prokaryotic expression plasmid of human PSCA gene has been successfully constructed. The GST-PSCA fusion protein may express and be purified in E. coli BL21,and it lays a foundation for further study on the anti-prostate cancer gene vaccine.

Purines and pyrimidines have widespread and specific action in many tissues of both invertebrates and vertebrates. These compounds have powerful physiological roles in both short-term actions of neurotransmission, exocrine and endocrine secretion, and regulation of immune cell function, and long-term actions of cell growth, cell differentiation and proliferation in the development and regeneration.

Objective:To evaluate the clinical outcome of botulinum A toxin(BTX-A)injection into external sphincter combined with oral baclofen in treatment of detrusor-external sphincter dyssynergia(DESD)after spinal cord injury(SCI). Methods:A total of 38 urodynamic examination-confirmed DESD patients,male 31 and female 7,with an average age of (36.5?17.8)years old,were included in this study.200 U of BTX-A toxin was dissolved in 8 ml of normal saline and the solution was injected at 8 different sites(1 ml per site)of the external sphincter via a 5F flexible cystoscopic needle.On the second day,9 patients(BTX-A+baclofen group)were randomly selected for baclofen oral administration,3/d for 3 months; the other 26 patients were taken as control.Urodynamic examination was repeated in all patients 4 weeks later;the voiding diary and urodynamic outcomes were compared before and after treatment.The adverse and toxic effects were observed in the patients who were followed up for 2-9 months.Results:One month after treatment the voiding and storing functions of bladder were improved to different degrees,with the mean maximum uroflow rate(Qmax),the mean urine volume,the mean maximal cystometric capacity and the bladder compliance increased significantly and the mean postvoid residual urine volume and the mean maximal voiding pressure decreased significantly(all P

Objective To provide an experimental basis for long-term in vitro proliferation,tissue construction and function maintaining of human primary hepatocytes by preparing three-dimensional (3D) porous specific extracellular matrix (ECM) derived from porcine liver with different decellularizing methods.Methods The porcine liver tissue slices were treated using six different decellularization/oxidation ways,and the decellularization extent and ECM structure were evaluated through qualitative and quantitative analysis.Results The decellularized liver-ECM could maintain the original shape during the whole process of the decellularization.HE staining showed that the cellular components and nucleus disappeared in the decellularized ECM,indicating that all of these six decellularization methods can completely decellularize the porcine liver tissue slices.Determination of DNA content showed that 91％ ～ 97％ of cell components have been removed.Electron microscopy scanning observed that the pore sizes and ultrastructures of the liver ECMs under six decellularization treatments were significantly different.Conclsion The six decellularization/oxidation methods evaluated in this study could successfully create a 3D specific decellularized liver ECM with porous ultrastructure,which further lays basis for the development of a novel in vitro 3D culture model for human hepatocytes.
