OBJECTIVETo observe the clinical effect of Shugan Yiyang Capsules combined with sertraline in the treatment of premature ejaculation (PE).

METHODSWe randomly assigned 192 PE patients to receive sertraline hydrochloride 50 mg qd (control group, n = 96) or sertraline hydrochloride 50 mg qd plus Shugan Yiyang Capsules at the dose of 4 capsules tid ( combination therapy group, n = 96) , both for 6 weeks. We compared the intravaginal ejaculatory latency time (IELT) and Chinese Index of Premature Ejaculation ( CIPE) scores between the two groups of patients before and after medication and at 6 weeks after drug withdrawal.

RESULTSCompared with the baseline, the IELT was significantly increased after 6 weeks of medication in the combination therapy group ([1.41 ± 0.53] vs [6.69 ± 3.56] min, P < 0.05) and the control group ([1.43 ± 0.48] vs [5.37 ± 2.91] min, P < 0.05), and so was the CIPE score in the former (9. 80 ± 2.06 vs 21.62 ± 4.76, P < 0.05) and the latter group ([9.41 ± 1.97] vs [20.85 ± 4.83] , P < 0.05). In comparison with the pre-medication indexes, the IELT ([3.77 ± 1.63] min) and CIPE score (16.92 ± 3.37) of the combined therapy group were remarkably improved at 6 weeks after drug withdrawal (P < 0.05), but not those of the control ([1.19 ± 1.34] min and 10.59 ± 2.38, P > 0.05).

CONCLUSIONShugan Yiyang Capsules combined with sertraline have a definite and lasting effect on premature ejaculation.

Currently, bacterial resistance situation in health care settings is very serious in China, and the prevalence of a variety of common multidrug-resistant bacteria and pan-resistant bacteria are relatively high. Drug-resistant bacteria in Gram-positive bacteria are mainly methicillin resistant Staphylococcus aureus ( MRSA ) and macrolide-resistant Streptococcus, while glycopeptide-resistant enterococci are still at a low level.The clonal distribution of MRSA and mechanisms of Streptococcus resistance in China are different from those in European and American countries.Cephalosporins and quinolones resistance are the marked characteristic of Enterobacteriaceae with a high occurrence over 60%. Carbapenem-resistant Klebsiella pneumoniae shows a rapid upward trend, and producing KPC-2 type carbapenemases is the main mechanism of its resistance.Resistance in Pseudomonas aeruginosa is relatively stable, with resistant rates ranging from 20%to 30%.Multi-drug resistant Acinetobacter baumannii is a big problem in clinic.More than 50% Acinetobacter baumannii strains are resistant to carbapenems and cephalosporins, and tigecycline-resistant Acinetobacter baumannii is increasing.This paper systematically reviews the status and characteristics of bacterial resistance in last five years with referring to the surveillance data of antimicrobial resistance and the findings of related mechanisms.

Objective Through investigation and training in the knowledge and skills of pre hospital emergency treatment in Xuzhou highway traffic policemen,we explored a more targeted and more effective first-aid skills training program.Methods Based on our hospital emergency center 91 highway traffic policemen were randomly assigned to 3 first aid skills training groups,group 1 received theoretical training and operational training,group 2 was given the same theoretical training and operational training after DVD player,group 3 took the same method as that of group 2,besides,situational training was given to group 3.The emergency treatment technique was evaluated post training.Results After the training,the scores of 3 groups were different from each other,group 3 had the best results compared with group 1 and group 2.Conclusions The highway traffic policemen had poor emergency treatment knowledge.They should be trained with first aid knowledge and skills as well as cardiopulmonary resuscitation training.

Objective To construct prokaryotic vector and express human herpes virus 8 (HHV8) small capsid protein open reading frame 65 (ORF65) in Escherichia coli.Methods DNA was extracted from BCB-1 cells (HHV8-positive but EBV-negative).HHV80RF65 coding sequence was amplified by PCR and inserted into the prokaryotic expression vector pThioHisA.Recombinant plasmid was transformed into E.coli BL21 to express fusion protein induced by IPTG.The expressed products were purified by affinity chromatography on Ni-NTA resin.The antigenieity and the specificity of the recombinant proteins was identified by Western blot with HHVS-positive serum samples.ELISA coating with the recombinant proteins was used to screen 568 serum samples,which were simultaneously detected by IFA kit(Biotrin) and ELISA kit(Qiagen).Results Gene sequencing showed that the target gene was identical with that of HHV8 standard species,the 31 500 fusion protein was found in SDS-PAGE.ELISA coating with the recombinant proteins had a good agreement with IFA kit(Biotrin) and ELISA kit(Qiagen).The detection for the clinical samples showed the ELISA kit was feasible,applicable and consistant.Conclusion The recombinant proteins showed good antigenicity,and it is valuable for further study on HHV8 specific antibody detection.

Background The identification of mesenchymal stem cells(MSCs) have provided exciting prospects for cell-based regeneration after myocardic infraction.However cell therapy have inherent limitations such as low survival rate of transplanted cells and insufficient cell number.It is known that cell-matrix adhesion plays a key role in cell proliferation,differentiation and survival,and chemokine CXCL12 may involved in these prcesses.Transfected mesenchymalstem cells with CXCL12 for local secretion of CXCL12 and then explored CXCL12 triggered adhesion of mesenchymal stem cells to extracellular matrix proteins.Mesenchymal stem cells was transfected with CXCL12.?V and ?3 integrins content was evaluated by Western blot analysis.Cell adhesion to extracellular matrix was examined in vitro and cell prolife-ration after transplantation in vivo.Transfection of CXCL12 resulted increased CXCL12 in situ.Increased CXCL12 induced elevated adhesion to fibronectin in vitro and higher survival in vivo.CXCL12 mediated adhesion and proliferation was established by ?V and ?3 integrin subunits.Chemoattractive mechanisms are involved in adhesion processes of mesenchymal stem cells.Increased CXCL12 leads to enhanced expression of ?V and ?3 integrins,which may augment cell survival,proliferation and differrentiation.

Objective To study the clinicopathologic features and differential diagnosis of deep angiomyxoma(DAM). Methods Seven cases of DAM were collected from 2000 to 2008. All the patients were examined by microscopy and immunohistochemistry. Results 6 patients with DAM were females and 1 was male, with median age of 48.5 years. Median maximum dimension was 5.9cm, with invasive growth pattern. The tumor cells of DAM were infantile, spindle or stellate,diffuse and nodular arrangement. A distinctive histologic feature of DAM was its vascularity. Non-arborizing, thin-wall, ectastic capillaries or more commonly, small thick-wall vessels were dispersed throughout the tumor. Mast cells and extravasated red blood cells were frequently found in the stroma, immunohistochemical study showed that 7 cases were positive for vimentin, desmin, ER and PR, 5 for CD34 and SMA, and negative for S-100 and CK. Conclusion DAM is a rare soft tumor that occurs principally in the vulval and vagina region of woman. Misdiagnosis has happened frequently. Immunohistochemical staining are helpful to diagnosis for DAM, but no significance to distinguish it.

AIM: To investigate the differential expression profile between nasopharyngeal carcinoma cell line CNE1 and its steady EBV-LMP1-transfected cell line CNE1-LMP1, and to explore the regulatory effect of LMP1 on oncomiRs expression in CNE1 cell line. METHODS: A microRNA array that targets 132 of the most well studied oncomiRs was used to detect the expression profile of CNE1 and CNE1-LMP1. qRT-PCR assay were used to verify the expression data detected by microarray. RESULTS: Among the restricted 132 miRNAs, 30 were detectable. Among which, 30 were expressed in CNE1-LMP1, 19 in CNE1 and 11 were specifically expressed in CNE1-LMP1. Among the 19 shared miRNAs, the expression level of 6 miRNAs (hsa-miR-19b, hsa-miR-17-3p, hsa-miR-22, hsa-miR-149, hsa-miR-150 and hsa-miR-188) elevated over two folds in CNE1-LMP1. No decrease in miRNA expression more than two folds was observed. qRT-PCR confirmed the expression difference of these six miRNAs (P<0.01). Among the 11 specifically expressed miRNAs in CNE1-LMP1, hsa-miR-122a showed the highest expression level surpassing the internal control sample. CONCLUSION: Our data suggest that LMP1 may play an important role in regulating the expression of miRNAs in tumor, which may be another important pathway employed by LMP1 in the development of nasopharyngeal carcinoma.

OBJECTIVETo compare the difference of Euphorbia Pekinensis Radix before and after being processed with vinegar in the toxicity on rat small intestinal crypt epithelial cells IEC-6, and make a preliminary study on the mechanism of detoxication of Euphorbia Pekinensis Radix processed with vinegar.

METHODWith rat small intestinal crypt epithelial cells IEC-6 as the study object, the MTT method was adopted to detect the effect of Euphorbia Pekinensis Radix before and after being processed with vinegar on IEC-6 cell activity. The morphology of cells were observed by the inverted microscope. The down-regulated mitochondrial apoptosis pathway of enterocytes caused by the vinegar processing was analyzed by using the high content screening.

RESULTCompared with the negative control group, the proliferation inhibition experiment showed that Euphorbia Pekinensis Radix showed a relatively high intestinal cell toxicity (P < 0.01). The results of HCS analysis showed that Euphorbia Pekinensis Radix could significantly reduce the cell nucleus Hoechst fluorescence intensity and mitochondria membrane (P < 0.05, P < 0.01), and increase Annexin V-FITC and PI fluorescence intensity and membrane permeability (P < 0.01, P < 0.01, P < 0.01). After being processed with vinegar, compared with Euphorbia Pekinensis Radix groups with different doses, Euphorbia Pekinensis Radix processed with vinegar could significantly decrease the cell proliferation inhibition effect on enterocytes, increase the cell nuclear Hoechst fluorescence intensity and mitochondria membrane (P < 0.05, P < 0.05), and decrease Annexin V-FITC and PI fluorescence intensity and membrane permeability (P < 0.01, P < 0.01, P < 0.05), and showed a certain dose-effect relationship.

CONCLUSIONThe vinegar processing can further reduce the toxicity of Euphorbia Pekinensis Radix on enterocytes. Its possible mechanism can decrease the effect of Euphorbia Pekinensis Radix on the permeability of IEC-6 cell membrane, so as to provide a basis for further explanation of the detoxication mechanism of Euphorbia Pekinensis Radix processed with vinegar.
