·AIM:To determine the effect of anterior-posterior joint surgery on choroidal thickness in patients with proliferative diabetic retinopathy (PDR). · METHODS: A retrospective, case - control study enrolled 60 eyes of 60 patients with PDR diagnosed at Qingdao Municipal Hospital. The patients, who had conditions that warranted anterior - posterior joint surgery,were divided into a clinically significant macular edema group (PDR/CSME+;31 patients,31 eyes) and a non-CSME group (PDR/CSME-;29 patients,29 eyes). Twenty-seven eyes of 27 normal patients were included in the control group. All affected eyes underwent anterior - posterior joint surgery. After surgery, the subfoveal choroidal thickness (SFCT), and the nasal choroidal thickness (NCT) and temporal choroidal thickness (TCT), which were obtained at a distance of 1500μ m from the fovea in the nasal and temporal directions, respectively, were measured in the control and PDR groups by enhanced depth imaging spectral domain optical coherence tomography (EDI-SDOCT) at 1wk,1,3, and 6mo after surgery. Changes in choroidal thickness after anterior - posterior joint surgery were compared between the groups. ·RESULTS:The SFCT,NCT,and TCT were significantly thicker at 1mo than at 1wk, 3, and 6mo after surgery in the PDR/CSME+ and PDR/CSME- groups(P<0.05). The SFCT, NCT, and TCT were significantly thinner at 6mo than at 1wk,1,and 3mo after surgery in the PDR/CSME+and PDR/CSME- groups(P<0.05). The SFCT,NCT,and TCT in the PDR/CSME+ and PDR/CSME- groups at 1wk, 1, and 3mo after surgery were significantly thicker than those in the control group (all P<0.05), but the SFCT, NCT, and TCT at 6mo after surgery showed no significant difference compared with the control group (all P>0.05). There was no significant difference in the SFCT,NCT, or TCT at 1wk, 1, 3, or 6mo between the PDR/CSME+ and PDR/CSME- groups (P>0.05). ·CONCLUSION:The choroidal thickness of PDR patients increases within 1mo after surgery, and decreased after 1mo,but is not significantly different between the control group and the PDR groups at 6mo after surgery. Whether PDR is associated with CSME has no effect on the choroidal thickness after surgery.

OBJECTIVESTo study the inhibitory effect of KF-950 on human acrosin and sperm acrosome.

METHODSHuman acrosin was extracted and purified with 2% acetic acid, and its residual activity was evaluated by BAEE/ADH assay after treated with different concentrations of KF-950. ABC assay was used to observe the effect of KF-950 on human acrosome with Biotin-PSA as a probe.

RESULTS1. The activity of normal sperm acrosin was (37.65 +/- 4.47) U/L. 2. The residual activity was inversely related to the concentration of KF-950 (r = -0.998), and had a dose-response curve. The result could be described by Y = 7.57-1.895X. 3. With increase of KF-950 concentration and prolongation of action time, the staining rate of acrosome obviously dropped (P < 0.01).

CONCLUSIONSKF-950 directly inhibits acrosin activity and assumely injures sperm acrosome. It might be a new kind of highly effective inhibitor.

Oxidative stress is implicated in male infertility and significantly higher reactive oxygen species are detected in 25% of infertile males. Although different agents of various alternative medicines, including traditional Chinese medicine, have been tried with varying success, evidence remains limited on whether and how much herbs or supplements might help increase the anti-oxidant ability of the sperm. This study examined the anti-oxidative effects of icariin, a flavonoid isolated from Herba Epimedii, on the human sperm. We prepared the FeSO4/H2O2-damaged human sperms, which were co-cultured with icariin in vitro, and then observed the changes of the sperm by employing Raman micro-spectroscopy. The results showed that Raman mapping with a 514 nm excitation laser allowed clear differentiation of the nucleus, neck, and, in particular, the mitochondria-rich middle piece of a human sperm cell. The effect of icariin on different organelles of the sperm was quantified by localized spectral Raman signatures obtained within milli-seconds, and icariin could keep the "Raman fingerprint" of the human sperm the same as the control groups, suggesting that icariin could protect the human sperm from being damaged by FeSO4/H2O2. Icariin may serve as a tonifying and replenishing agent of herbal origin for enhancing reproductive functions.

OBJECTIVETo understand the characteristics of embB gene mutation of Mycobacterium tuberculosis (MTB) isolates from tuberculosis patients in Chongqing, and the value of embB306 as a molecular marker used to diagnose ethambutol (EMB)-resistant MTB strains.

METHODSDirect sequencing was used to analyze the polymorphism of embB mutation in 51 EMB-resistant MTB strains and 50 EMB-sensitive MTB strains. And diagnostic testing was used to evaluate the value of embB306 as a molecular marker of EMB -resistant MTB strains as compared with the traditional sensitivity test.

RESULTSAll 34 of 51 EMB-resistant strains (66.7%) and 3 of 51 EMB-sensitive strains (6%) had had embB306 mutation. The embB306 mutation rate in EMB-resistant strains coming from previously treated case was 87.5%, showing significantly higher than that from new cases (48.1%, P < 0.01); embB306 mutation rate was increased with the number of the resistant drugs; embB306 mutation serving as a marker to diagnose EMB-resistant MTB strains comparing with the traditional sensitivity test, had the rate of sensitivity = 66.7%, specificity = 94.0%, accuracy = 80.2% and Youden index = 60.7%.

CONCLUSIONembB306 mutation should be the main mechanism of MTB resistance to EMB in Chongqing, showing an association with the history of the treated and numbers of the resistant drugs. embB306 mutation should be a good marker to diagnose EMB-resistant MTB strains.

This study is to investigate the effect of rhein lysinate on inducing human breast cancer cell line SK-Br-3 apoptosis and the role of HER-2 signal pathway in the apoptosis. MTT assay was used to detect SK-Br-3 cell proliferation. Cell cycle and apoptosis were analyzed by flow cytometry. The protein expression and the protein phosphorylation of HER-2 signal pathway were detected by Western blotting. The level of HER-2 mRNA was detected by RT-PCR and the level of HER-2 expression was also detected by immunofluorescence cytochemical methods. The results showed that rhein lysinate remarkably inhibited breast cancer SK-Br-3 cell proliferation. The IC50 value for 48 h treatment was 85 micromol x L(-1). Apoptosis in SK-Br-3 cells was induced by rhein lysinate in a dose dependent manner. The protein expressions of HER-2, NF-KB, and the protein phosphorylation of HER-2 were downregulated, however the protein expression of p53 and p21 was upregulated after rhein lysinate treatment. The level of HER-2 mRNA decreased by using RT-PCR assay and the level of HER-2 expression was also decreased by using immunofluorescence cytochemical assay after rhein lysinate treatment. It can be concluded that rhein lysinate could inhibit SK-Br-3 cell proliferation and induce apoptosis. HER-2/NF-kappaB/p53/p21 signal pathway might be involved in this process. Rhein lysinate has a good prospect to be an adjuvant chemotherapeutic drug.

BACKGROUNDA monoclonal antibody would be an effective tool for the detection of circulating antigens in the serum of patients with schistosomiasis, but the traditional way of producing monoclonal antibodies is not cost-effective. The objective of this study was to find a new method for the large-scale production of monoclonal antibodies against Schistosoma japonicum (Sj).

METHODSA phage display antibody library for Sj was constructed. To obtain a single-chain variable fragment antibody (scFv) against Sj, the library was screened with metabolic antigens from adult Sj worms (Sj-MAg) using enzyme-linked immunosorbent assay. The soluble scFvs selected were used to detect Sj antigens in the serum of acute and chronic schistosomiasis patients.

RESULTSSix positive clones with good reactivity to Sj-MAg were obtained from the phage display antibody library of about 1.07 x 10(6) individual clones. Only two of these six clones bound specifically to Sj-MAg and were chosen for further analysis. Specific soluble anti-Sj-MAg scFvs were produced by inducing the 2 clones with isopropyl-D-thiogalactopyranoside. The characteristics of the scFvs were then determined. The results of Western blot showed that these scFvs could bind to Sj-MAg specifically and had a molecular weight of about 31 kD. When testing serum from schistosomiasis patients with one of the two specific scFvs, its sensitivity was found to be 60% and 37% in acute and chronic patients, respectively, with a specificity of 90%. When the two specific scFvs were combined, their sensitivity was found to be 75% and 57% in acute and chronic patients, respectively, with a specificity of 85%.

CONCLUSIONSThe results indicate that the scFvs are potentially useful for the diagnosis of schistosomiasis. The library construction also provides a useful tool for the further screening of other antibodies for both diagnostic and immunotherapeutic applications and for epitope analysis and vaccine design.

OBJECTIVETo study the effects of genotypes of HBV and HBeAg on the response to PEG-interferon alpha (PEG-IFN) in chronic hepatitis B (CHB) patients.

METHODSPCR-RFLP and S gene sequencing were conducted in 42 CHB patients.

RESULTSThe sustained response (SR) rates were 66.7% in genotype B and 27.3% in genotype C group. The P value was 0.039 by the Pearson Chi-square test, while it was 0.06 by the Fisher's exact test. The results suggested a trend that patients with genotype B HBV compared to genotype C had better SR to PEG-IFN therapy, although the difference was not significant. Results also showed that SR rate in patients with HBeAg-negative CHB (7/8 87.5%) was significantly higher than that in HBe+ CHB patients (8/21 38.1%, P < 0.05).

CONCLUSIONOur results indicate that HBV genotype and HBeAg, especially the later, are main factors for predicting PEG-IFN therapy response in CHB patients.

The prokaryotic expression plasmid pQE30-HN of hemagglutinin-neuraminidase (HN) protein gene of bovine parainfluenza virus type 3 (BPIV3) strain HJ-1 was expressed by IPTG induction in E. coli XL1Blue. The recombinant HN protein(rHN) was purified by electroeluting method, and used as coated antigen. An indirect enzyme-linked immunosorbent assay (ELISA) was developed to detect the antibody valence of BPIV3. The best working conditions of ELISA were as follows: the antigen concentration was 6 microg/mL; the serum dilution was 1:50; the blocking reagent was 5% skimmed milk; the blocking time was 60 min at 37 degrees C; the second antibody concentration was 1:10 000; The cut-off value was 0.30. The method revealed a good specificity, no cross-reaction to the positive sera of BCV, IBRV or BRSV was observed. We applied the method to detect 323 serum samples of dairy cow in Heilongjiang Province, the seropositivity rate of BPIV3 was about 58%. The indirect ELISA established provided a technological basis for the development of ELISA kit.
