OBJECTIVETo discuss the results and significance of the detection of the CFTR gene mutation in azoospermia patients with congenital unilateral absence of the vas deferens (CUAVD).

METHODSWe collected peripheral blood samples from 6 azoospermia patients with CUAVD for detection of the CFTR gene mutations and single nucleotide polymorphisms. We analyzed the genome sequences of the CFTR gene in comparison with the website of the UCSC Genome Browser on Human Dec. 2013 Assembly.

RESULTSMissense mutation of c. 592G > C in exon 6 was found in 1 of the 6 azoospermia patients with CUAVD and splicing mutation of c. 1210-12T[5] was observed in the noncoding region before exon 10 in 2 of the patients, both with the V470 haplotype in exon 11.

CONCLUSIONMutations of the CFTR gene can be detected in azoospermia patients with CUAVD and the detection of the CFTR gene mutation is necessary for these patients.

OBJECTIVETo observe the correlation between constitution of yin deficiency syndrome (YDS) and polymorphism of HLA-DQA1/treatment response of Peg-lFNalpha therapy in HBeAg positive chronic hepatitis B (CHB) patients, and to explore constitution of Chinese medicine (CM) in response of interferon therapy.

METHODSTotally 120 HBeAg positive CHB patients who were treated with Peg-IFNalpha were enrolled, and assigned to YDS group (59 cases) and non-YDS group (61 cases) according to classification of CM constitutions. All patients were subcutaneously injected with Peg-IFNalpha-2b (1.0 microg/kg body weight) or Peg-IFNalpha-2a (180 microg), once per week. Effective efficacy was primarily judged when complete response (CR) or partial response (PR) was obtained at month 6. Those with CR or PR completed 1 year therapeutic course. HLA-DQA1 gene types were detected by polymerase chain reaction sequence specific primers (PCR-SSP). The distribution difference of CM constitutions in patients with CR or PR and their inter-group HLA-DQA1 allele frequency were compared.

RESULTSDifferent treatment responses of Peg-IFNalpha were observed in CHB patients of two different CM constitutions. The ratio of CR + PR was 61.0% (36/59) in YDS group, obviously lower than that in NYDS group [78.7% (48/61), P < 0. 05]. Patients with CR had a lower allele frequency of HLA-DQA1 * 0501 than those with no-response [14.8% (8/54) vs. 30.6% (22/72)] with statistical difference (P < 0.05). Patients with CR had a higher allele frequency of HLA-DQA1 * 0601 than those with no-response [18.5% (10/54) vs. 5.6% (4/72)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0301 was lower in YDS group than in non-YDS group [2. 5% (3/118) vs. 9.8% (12/122)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0501 was higher in YDS group than in non-YDS group [33.9% (40/118) vs. 18.9% (23/122)] with statistical difference (P < 0.05). Yet statistical significance was lost after adjustment (Pc > 0.05 for both).

CONCLUSIONSBoth constitutions of CM and HLA-DQA1 gene polymorphism af- fect HBeAg positive CHB patients' response to Peg-INFalpha. Constitutions of YDS and HLA-DQA1 * 0501 was not favorable to response, their association needed to be further studied.

OBJECTIVETo investigate the effect of miRNA-101 on the expression of the enhancer of zeste homolog 2 (EXH2) in human androgen-independent prostated cancer LNCaP cells.

METHODSWe divided LNCaP cells into a blank control, a negative control, and a miRNA-l01 transfection group, constructed the vector by transfecting synthetic miRNA-101 mimics into the LNCaP cells, and evaluated the efficiency of transfection by fluorescence microscopy. Then we determined the expression level of EZH2 mRNA by qRT-PCR in the three groups of cells and that of the EZH2 protein in the negative control and transfection groups by Western blot.

RESULTSGreen fluorescence signals were observed in over 70% of the LNCaP cells in the transfection group after 24 hours of transfection. At 72 hours, the expression of miRNA-101 was significantly upregulated in the transfected cells (P < 0.01), that of EZH2 mRNA was remarkably lower in the transfection group (0.01 ± 0.10) than in the blank control (0.95 ± 0.40) and negative control (0.86 ± 0.30) groups (both P < 0.01), and that of the EZH2 protein was increased in the negative control but decreased in the transfection group with the extension of culture time.

CONCLUSIONmiRNA-101, with its inhibitory effect on the expression of EZH2 in LNCaP cells, is a potential biotherapeutic for prostate cancer.

Objective To report clinical study of diabetic foot with microsurgical treatment.Methods 32 cases basing on physical treatment underwent operation which included reconstruction of vessel under DSA and flap transfer and relaxation of nerves.Results 8 eases were examined with DSA after operation,it showed that the bypass grafts were unobstructed and the distal blood were improved;All flap were lively. Conclusion The ulcer of the patients with diabetic foot was closed early and the blood supply of the limb have been reconstructed by microsurgical treatment,it can not only avoid amputation or lower the limb amputation level,but also improve the life quality of patients and obtain social benefit.

Objective To compare the effect of cimetidine associated with bletilla striata,rhubarb on peptic ulcer,cushingulcer,acute erosive gastritis,bleeding of esophagus and gastric funds varicosis of cirrhotic portal hyper- tension and gastri cancer.Methods 136 patients with upper gastrointestinal hemorrhage were randomly divided into 2 groups.The treated group(n=69)was given cimitidine associated with bletilla striata,rhubarb and the control group(n=67)was given cimitidine only.The effects of hemostasis in 2 groups were observed.Results The effect of hemostasis in the treated group was better than that in the control group on peptic ulcer,cushingulcer,acute ero- sive gastritis and gastric cancer(P＜0.05).There were no difference between 2 groups about bleeding of esophagus and gastric funds varicosis of cirrhotic portal hypertension(P＞0.05).Conclusion The effect of hemostasis on up- per gastrointestinal hemorrhage treated by integrated traditional Chinese medicine and western medicine might achieve better on cushingulcer,acute erosive gastritis,peptic ulcer and gastri cancer.It has less adverse effect and more safety.
