In recent years ,matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) is a new organic soft ionization mass spectrometry which can identify and classify microorganism by directly using the sam-ple itself or cultivate colonies on petri dish in a few minutes .This new and simple method reduces the cost of consumables and the time of diagnosis greatly .Its reliability and accuracy have been shown in many studies and different system devices have al-ready been on the market .In the near future ,MALDI-TOF MS will have a broader prospect .This mass spectrometry will be-come an effective and fast microbial identification technology to replace the conventional method .In this article ,we will review the principles of MALDI-TOF MS ,its development and application ,its advantages and shortcomings which compared with tra-ditional methods at the present stage ,and the emphasis will focus on the application characteristics of MALDI-TOF MS in mi-crobial systems .

HIV/AIDS has posed an increasingly serious issue in China. In recent years, Chinese government has taken further intensified efforts to combat HIV/AIDS with high-level political commitment, supportive policy development, increased financial allocation, large-scale of governmentled initiatives, expanded international cooperation and great involvement of non-governmental organizations. Meanwhile gaps and challenges coexist impacting the implementation and the results of national HIV/AIDS programs. Thus, further government efforts are needed to improve and tailor the actions to meet the requirement of HIV/AIDS control in China.

Objective To explore the feasibility,efficent and safety of transuretheral enucleation of prostate combined with extraction of gland pieces from small lower mid-line incision(LMI).Methods One hundred and twelve patients with large benign prostatic hyperplasia were treated by modified transurethral nucleation of prostate,during the operation,the gland was divided into 2-3 parts which were extracted from a small LMI.Results In this method the operation time was 60-120 min with an average time of(70 ± 10)min and blood loss during operation was 60-400 ml with an average of(150 ± 15)ml.There was no severe complication during and after operation.At the 3 month after surgery,the urine flow rate(Qmax)increased from (7.5 ±2.4)ml/s to(16.0 ±2.5)ml/s,and urine residual volume(RUV)decreased from(75 ± 15)ml to (25 ± 10)ml,international prostate symptom score(IPSS)decreased from 25.5±:4.5 to 8.4 ± 1.3,and the quality of life(QOL)decreased from 5.5 ± 0.4 to 1.2 ± 0.3.All these changes were statistically significant (t =28.53,36.19,37.16 and 59.53,Ps ＜ 0.05).At the 6 month,no complications,e.g.,permenant uroclepsia,urethrostenosis or erection disfounction occurred.Conclusion Transurethral enucleation of prostate combined with gland extraction from LMI for large benign prostatic hyperplasia is safe and effective and it is worthy of generalization in clinical practice.

Objective:To investigate depression of elderly patients in general hospital Method:315 patients aged 60 or above in Tongji hospital were screened with CES-D (Chinese version of Center of Epidemiological Survey-Depression) Results:70 of them (22%) definitely had depression, 53 were suspected of depression Female had higher scores in CES-D than male The less educated had higher score in CES-D Multiple regression showed poor education as a risk factor for depression in elderly patients Discussion: Routine screening for depression in elderly patients in general hospital is necessary

Objective: To study the effect of fluoxetine in treatment of anxiety and depression of patients with patients with persistent somatoform pain disorder Method:62 patients with persistent somatoform pain disorder were treated with fluoxetine 20mg/d for 6 weeks The clinical effect was assessed with HAMA and HAMD Result:At the end of the 6th week, the responsive rate was 79 03% All item scores of HAMA and HAMD decreased The remission rates of three subscores of HAMD were retardation 75 8%, anxiety/somatization 69 4% weight 45 2% The remission rates of two subscores of HAMA were as follows: mental anxiety 71 0%, somatic anxiety 72 6% Conclusion:Fluoxetine is effective in treatment of anxiety and depression of patients with persistent somatoform pain disorder

Object To study the suitable conditions for the pac king of volatile oil in Rukang Capsule, which will inhibit the loss of volatile oil. Methods With the packing rate as index, even design method wa s applied to investigate the optimal packing conditions. Results The optimal packing conditions were found to be: volatile oil volume (mL)-cy c lodextrin (g)=1∶6, the packing process should be carried out for 120 min under 40 ℃. Conclusion The repetition rate is very good in the repeti tion experiments.

Objective To explore the clinical classification of upper lid dermatochalasis in mid dle-aged and elderly women for choosing appropriate surgical methods and evaluating the efficacy of the treatment.Methods A lot of 98 cases of middle-aged and elderly women above 40,who underwent surgical treatment between January 2005 and September 2015,were retrospectively analyzed.The dermatochalasis was classified according to the relaxation of upper lid soft tissue,eyebrow ptosis and the effect of eye function.Therefore,four surgical treatments were designed for patients-upper eyelid incision,infraeyebrow incision,eyebrow lifting and upper eyelid incision plus eyebrow lifting.Results Of the 133 treated cases,the post-operative cosmetic result was assessed as very satisfactory in 107 (80.4％) cases;as satisfactory in 19 (14.3％) cases,and as dissatisfactory in 7 (5.3％) cases.Conclusions The key to satisfactory treatment of upper lid blepharoplasty for middle aged and elderly women lies in designing personalized treatments and choosing appropriate surgical methods according to the classification of upper lid relaxation.

The course of pharmaceutical analysis for pharmacy undergraduate students in National University of Singapore and China Pharmaceutical University was compared, in terms of curriculum, lecturing, assessment and practical teaching.This study provides in-depth analysis by the lecturers from both universities,and can provide reference for teaching reform and course construction of pharmaceutical analysis.

AIM: Constructing plasmid that expresses human plasminogen kringle 5 gene to analyze the gene expression in E.coli. METHODS: The gene of human plasminogen kringle 5 was inserted into plasmid PBV220 EcoRI site by gene manipulation techniques and was transformed to E.coli TGI. The gene expression was observed by SDS-PAGE. RESULTS: Expression vector PBVK5 was constructed, and human plasmingen kringle 5 gene product was obtained at 42℃ induction. CONCLUSLON: Expression product of human plasminogen kringle 5 gene was soluble form of proteins, and the expression amount was 9.8% in E.coli TGI total proteins.

Objective To evaluate the middle and short-term effects of integrative cognitive training on mild cognitive impairments(MCI).Methods All the participants with MCI aged over 70 years were selected from one sub-district of Putuo District,Shanghai and divided into cognitive intervention group (n=46) and control group (n=35).The integrative cognitive training was conducted in 24 sessions for 12 weeks.All subjects were assessed by Neuropsychological Test Battery for Elderly (NTBE) and by a questionnaire of Shanghai Health Survey for the Elderly (VER2006)at baseline,follow-up and one-year follow up phases.Results At baseline phase,semantic relations test in NTBE was better (t=2.13,P=0.037),verbal fluency test (vegetables) in NTBE was worse(t =-2.25,P=0.038) in intervention group than in control group,while there were no significant differences in scores of other neuropsychological tests between intervention group and control group(all P＞0.05).At follow up phase,16 subscales in reasoning test of NTBE were improved (t=-2.70,P=0.010)and 2 subscales were declined in cognitive intervention group(all P＜0.05).9 subscales in semantic relations test of NTBE (t=-2.27,P=0.013) were improved and 5 subscales were declined in control group (all P＜ 0.05).Comparison between groups at one year follow-up showed that 5 subscales in reasoning test of NTBE (F=16.80,P=0.000) were better in intervention group than in control group(all P＜0.05).General linear model (GLM) with repeated measures at three time points showed that 4 subscales in reasoning test of NTBE had a time-by group interaction (F=5.16,P=0.01).Conclusions Integrative cognitive training can improve cognitive function in patients with mild cognitive impairments,and the validity of reasoning ability can sustain one year.
