Objective To identity bacteria of bacteroides group by PCR.Method The universal primers were designed according to the sequence of 16S rRNA,then 13 strains bacteroides and the other non-bacteroides were amplified by PCR. PCR products were then sequenced and analyzed by Blast.Results Thirteen strains of bacteroides were amplified, and the non-bacteroides were not amplified. The pairs of primers had highly specificity.Comparing the gene sequences of the 13 strains,bacteroides with corresponding standard 16S rRNA sequences,the homology was from 81% to 100%.Conclusion The established PCR assay could specially amplify bacteroides and had good sensitivity with 100 genomes/ml.

OBJECTIVE: To discuss the challenges and opportunities for traditional pharmacies in digital network time. METHODS: Aiming at the problems occurring in the work of pharmacy and pharmaceutical care, we analyzed the meaning and deep impact of the using of network information technology in pharmacy .RESULTS: It is clear that the drug supply ori- ented pharmacies should be transformed to pharmaceutical care oriented pharmacies. It is very important to use computer high text to handle pharmaceutical information efficiently.CONCLUSION: The digital networks can extend the work of pharma- ceutical care in space and time and provide an opportunity to the development of pharmacies.

Objective:To search for common epitopes of(H5N1) from different areas in the world in order to develope epitope-bacterin by the way of immunoinformatics.Methods:Firstly,homologous degree of the amino acid sequence of VIA from different areas was compared on the basis of the database in Genebank with soft-ware ClustalW1.83.The common epitopes which were able to bind strongly to MHCⅠ molecule were selected.Results:Though homologous degree of amino acid sequence of VIA from different areas was not completely similar,there were some common epitopes among these strains analyzed.The common epitopes were shown to bind strongly with MHCⅠ molecule.Conclusion:These common epitopes may be used to develope epitope-bacterin for preventing infection of AIV(H5N1).

Objective To improve the mammographic diagnostic level of breast ductal diseases.Methods X-ray features,operationand pathologic findings in 166 cases of breast disease were retrospectively analyzed.Results The galactography of all 166 cases showed the manifestations including 78 cases of mammoductal ectasis with ductal dilatation,smooth wall;2 cases of ductal ectasis complicated by infection with ductal dilatation,inregular coarsening wall and interstitial extravasation of contrast medium;11 cases of mammoglandular cystic lobular hyperplasia with cyetic dilatation of terminal ducts in different sizes;49 cases of intraductal papilloma with sound as ovoid fillingdefects showing as interrupted smooth bordered,"cupping" in 26 cases of intraductal papillary carcinoma or intraductal carcinoma with post dilatation ductal stenosis and sigid "amputation" absuption together with sound cauliflower or inregular filling defects.In this series of 166 cases,75 cases vice prover to be tumor(45.1%) with malignancy in 26 cases(15.7%).Conclusion Galactography is an important method for diagnosis and differential diagrosis of mammoglandular disease with nipple discharge.

Objective To assess the effectiveness of repeated trans-cranial magnetic stimulation ( rTMS) in relieving post-stroke depression ( PSD). Methods PubMed, Embase, the Cochrane library, Web of Science, CNKI, WANFANG, and VIP were searched for reports of randomized, controlled trials of rTMS treatment of PSD published before June 2015. Crude standardized mean differences ( SMDs) and odds ratios with 95% confidence in-tervals ( CIs) were calculated for depression intensity and effectiveness rate after treatment using random or fixed effects models. Results Twenty-four studies involving 856 rTMS-treated patients and 802 control patients were in-cluded in the meta-analysis. The results showed that compared with the control group, PSD patients showed significant reductions in depression after rTMS treatment ( SMD=-1.36;95% CI-1.6 to-1.12;P≤0.05) . The total effective-ness rate in the treated group was 85% with a reduction in NIHSS score ( SMD=-0.82;95% CI-1.2 to-0.44;P≤0.05) . Subgroup analysis showed that neither the frequency of rTMS stimulation, the site stimulated, nor time after stroke had a significant influence on the effectiveness of rTMS. Additionally, a few studies reported adverse reactions after rTMS. Conclusion rTMS appears to be a safe and effective therapy for PSD. Further well-controlled trials may elucidate the mechanism underlying the placebo effects of the sham rTMS observed among PSD patients.

In landing phase, there would be a severe conflict between too many wounded soldiers at field and the shortage of immediate rescue. To solve that problem and according to the principle of "Keep up, Carry out, and Bring off ", a set of field portable first-aid unit has been developed to improve the rescue ratio of the field wounded soldiers.

OBJECTIVE To report a case of AIDS associated with penicilliosis marneffei and discriminate the morphology in bone marrow examination and cultural characteristic of Histoplasma capsulatum and Leishmania donovani.METHODS The three pathogens in bone marrow morphology and cultural characteristic were studied.RESULTS AIDS patient was often infected with P.marneffei,but we could differentiated easily from other pathogens because of its breeding by splitting up and the characteristis structure in bone marrow examination.CONCLUSIONS Isolation of the P.marneffei is the golden diagnosis standard,and the examination of bone marrow is important to diagnose P.marneffei infection.

Objective To investigate the diagnostic value of barium stury of small bowel obstruction due to various bowel diseases.Methods Barium meal study and enteroclysis (small bowel enema)were performed in 23 patients with incomplete small bowel obstruction due to small bowel diseases confirmed by operation.The imaging data were retrospectively analysed.Results Of the 23 patients,14 cases were malignancy,9 cases were benignant.Conclusion Both barium meal study and enteroclysis( small bowel enema) with air-barium double-contrast technique are of diagnostic value in incomplete small bowel obstruction due to small bowel diseases.

OBJECTIVE:To observe effects and safety of Kangfuxin solution combined with intense pulsed light in the treat-ment of rosacea. METHODS:A total of 50 rosacea patients in our hospital during May 2014-Jun. 2016 were divided into control group(25 cases)and observation group(25 cases)according to random number table. Based on oral administration of Metronida-zole tablets,control group received intense pulsed light. Observation group was additionally given Kangfuxin solution for local wet compress after 4 to 6 layers of gauze saturated with liquid,5-10 min,qn. Both groups received treatment for 4 weeks. Clinical effi-cacies,as well as symptom score and DLQI score were compared between 2 groups before and after treatment,and the occurrence of ADR was recorded. RESULTS:The response rate of observation group was 92.0%,which was significantly higher than 64.0%of control group,with statistical significance (P<0.05). Before treatment,there was no statistical significance in erythema,pap-ules,pustules,itching,telangiectasia score and total score,DLQI score with before treatment(P>0.05). After treatment,erythe-ma,papules,pustules,itching,telangiectasia score and total score,DLQI score of 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). The incidence of ADR in observation group was 16.0%,which was significantly lower than 40.0% in control group,with statistical significance(P<0.05). CONCLUSIONS:Kangfuxin solution combined with intense pulsed light show significant efficacy for rosacea,and can effectively improve erythema,papules,pustules,itching and telangiectasia,and improve the quality of life with good safety.
