AIM: To evaluate the efficacy of vitrectomy and pan-retinal photocoagulation followed with Ahmed implantation in management of neovascular glaucoma ( NVG) retrospectively.
METHODS: Vitrectomy combined with pan retinal photocoagulation and Ahmed implantation was performed on 15 cases ( 15 eyes ) with NVG. All patients were followed up for 12 ~ 36mo. The change of intraocular pressure (IOP), visual acuity, neovascularization of iris, complications were observed.
RESULTS: The visual acuity of 10 eyes was improved postoperative. IOP of postoperative 1, 6 and 12mo were decreased significantly compared with preoperative ( P<0.01 ) . Neovascularization of iris was reduced dramatically. No serious complications occurred.
CONCLUSION: Vitrectomy combined with pan retinal photocoagulation followed Ahmed implantation can manage NVG effectively.

Spermiogenesis is a complex process of differentiation and morphologic alteration, in which sperm acrosome formation is an important stage. Acrosome is an essential component of the sperm head, which develops in four distinct phases: Golgi, cap, acro- somal, and maturation, each supported by precise and orderly regulation of various genes. The regulatory genes which act on Golgi ap- paratus include GOPC, Hrb, SPATA16, PICK1, and CK2α', those involved in the cap phase are Fads2, syntaxin 2, Kdm3a, and UBR7, and participating in acrosomal and maturation phases are KIFC1, Rnf19a, and DPY19L2. The abnormalities of these genes may affect male fertility by influencing the connection of the nuclear dense lamina and acroplaxome with the nuclear membrane and then the fusion and transportation of vesicles. This review focuses on the genes involved in different phases of acrosome formation.

To evaluate the immunogenicity of inactivated SARS coronavirus (SARS-CoV), three groups of rabbits were immunized three times at 2-week intervals with inactivated vaccine + adjuvant, adjuvant,and normal saline respectively. Eight batchs of serum were sampled from the auricular vein at day 7 to day 51, and specific IgG antibody titers and neutralizing antibody titers were detected by indirect ELISA and micro-cytopathic effect neutralizing test. Antibody specificity was identified by proteinchip assay.Histopathological changes were detected by H&E staining. The results showed that, rabbits in the experimental group immunized with inactivated SARS-CoV all generated specific IgG antibodies with neutralizing activity, which suggested the inactivated SARS-CoV could preserve its antigenicity well and elicit an effective humoral immune responses. The peak titer value of specific IgG antibody and neutralizing antibody reached 1:40960 and 1:2560 respectively. In the experimental group, no obvious histopathological changes was detected in the H&E stained slides of heart, spleen, kidney and testis samples, but the livers had slight histopathological changes, and the lungs presented remarkable histopathological changes. These findings are of importance for SARS-CoV inactivated vaccine development.

The chemical constituents from the fruiting bodies of Lyophyllum decastes (Fr.) Singer were studied in this paper. Thirteen compounds were isolated and purified by column chromatographies on silica gel and Sephadex LH-20. Their structures were identified by MS and NMR data analysis as adenosine (1), 2R, 3S, 4S, 8E)-2-[(2'R)-2-hydroxyheneicosanoylamino]-8-octadecene-1, 3, 4-triol (2), (2R, 3S, 4S, 8E)-2-[(2'R)-2-hydroxypentacosanoylamino]-8-octadecene-1, 3, 4-triol (3), nicotinic acid (4), (4E, 8E) -2-N-2-hydroxytetracosanoyl-1-O-beta-D-glycopyranosyl-9-methyl-4, 8-sphingadienine (5), D-mannitol (6), ergosteryl-3-O-beta-D-glucopyranoside (7), tuberoside (8), (2R, 3S, 4S, 8E)-2-[(2'R)-2-hydroxybehenoylamino]-8-octadecene-1, 3, 4-triol (9),(2R, 3S, 4S, 8E)-2-[(2'R) -2-hydroxytricosanoylamino] -8-octadecene-1, 3, 4-triol (10), (22E, 24R)-ergosta-7, 22-dien-3beta, 5alpha, 6beta-triol (11), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol (12), and 5alpha, 8alpha-epidiory-(22E, 24R)-ergosta-6, 22-dien-3beta-ol (13), respectively. All the above compounds are first obtained from the mushroom and compounds 2-10 are reported to be obtained from the Lyophyllum for the first time.

OBJECTIVETo study the clinical effect of "Jin's three-needling" in the treatment of generalized anxiety disorder.

METHODSFifty-eight patients with generalized anxiety were randomly assigned to two groups equally, the medication group treated with anti-anxiety drugs and the acupuncture group with "Jin's three-needling". The treatment course was 6 weeks. The clinical effects were evaluated with Hamilton anxiety scale (HAMA), clinical global impression (CGI), and treatment emergent symptom scale (TESS) before treatment and at the end of 2nd, 4th, 6th week of the treatment course. The concentration of 5-hydroxytryptamine (5-HT) in platelet, and plasma levels of corticosterone (CS) and adrenocorticotropic hormone (ACTH) were measured with high performance liquid chromatography-electrochemical detection (HPLC-ED) method before and after treatment.

RESULTSThe clinical effects in the two groups were equivalent, while the adverse reaction found in the acupuncture group was less than that in the medication group (P < 0.05). The platelet concentration of 5-HT and plasma ACTH level decreased significantly in both groups after treatment with insignificant difference between the group (P < 0.05). The plasma CS level had no obvious change in the two groups after treatment as compared with that before treatment respectively.

CONCLUSION"Jin's three-needling" shows similar curative effect on generalized anxiety to routine Western medicine but with less adverse reaction, which may be realized through regulating the platelet 5-HT concentration and plasma ACTH level.

The SRY gene from buffalo (Bubalus bubalis) genome was amplified by the polymerase chain reaction ( PCR) with primers based on the sequence of Hostein SRY gene. The amplified fragment was 2005 bp include 5UTR ( 1 - 504bp) and 3'UTR(1196 - 2005bp). And the amplified fragment was cloned and sequenced. Sequence analysis showed that the coding region of SRY gene (505 - 1195bp) from buffalo was highly homologous with those of other bovine counterpart genes (96% homology) , especially in the HMG box region (99%homology). It was found that there were only signal on male buffalo genome on Southern blot,which indicate SRY gene are highly conservative on evolves.

To investigate the biological role of snake venom cystatin(sv-cystatin) in tumor progression, the cDNA of sv-cystatin amplified by PCR from pUC18-cystatin plasmid was cloned into methanol-inducible expression vector pPICZ?A. The linearized recombinant plasmid pPICZ?A-cystatin was transfered into Pichia pastoris, strain GS115 by electrophoration. Transfermants with phenotype Mut+ selected were identified by PCR analysis and induced in 1.0% methanol. The reombinant sv-cystatin protein was examined by SDS-PAGE, Western blot analysis. The molecular mass of expression product was about 14 kDa and approximately 16 mg/L of recombinant sv-cystatin was produced from one of GS115-cystatin transformants. The chromatography purified protein could reduce the activity of papain. The ability of B16F1 cells treated with recombinant sv-cystatin to invade the reconstituted basement membrane decreased significantly (P

A cellulase high-yield strain was identified and named as Trichoderma longibrachiatum SSL by ITS sequence identification. The endoglucanase1 gene (eg1) encoding endo-l,4-?-D-glucanase I was ampli-fied by RT-PCR method, which including 1386 bp and encoding 461 amino acid. Sequence analysis showed that: This gene has a more 90% homology with the T. longibrachiatum eg1 gene. The eg1 gene encoding the mature peptide was inserted into the Pichia pastoris expression vector pPIC9K, which resulted in construc-tion of the recombinant expression plasmid, pPIC9k-eg1. The pPIC9k-eg1 was then introduced into the host Pichia pastoris GS115. After the induction of methanol, extracellular recombinant endoglucanase I from the supernatant of the recombinant Pichia pastoris strain reached 73 U/mL. A clear strengthening of the protein bands, whose molecular weight is about 58 kD, appeared in the SDS-PAGE.
