Chinese Journal of Postgraduates of Medicine 2014;37(2):4-5
Objective To analyze the application value of central region cervical lymph nodes dissection in papillary thyroid microcarcinoma (PTMC) with clinically node-negative sides of neck stage.Methods Clinical data of 72 PTMC patients with clinically node-negative sides of neck stage were collected,and they were underwent total thyroidectomy,isthmic portion excision and contralateral lobus glandularis excision and neck dissection.A long term follow-up was made.Results Twenty-four patients were found central region cervical lymph nodes metastasis while other 48 patients were not found central region cervical lymph nodes metastasis.Followed up for 1.5-4.5 (3.4 ± 1.1) years,4 patients were found recurrent laryngeal nerve paralysis and recovered within 4 months.Four patients were found central region cervical lymph nodes metastasis after operation the 3rd years.Conclusions There is a tendency for PTMC patients with clinically node-negative sides of neck stage to occur central region cervical lymph nodes metastasis,it's necessary to perform prophylactic central region dissection.It can decrease the complications and improve the prognosis.

3.The efficacy of bioelectrical stimulation of the pelvic floor combined with acupuncture in treating detrusor urine weakness after transurethral resection of the prostate
Chinese Journal of Physical Medicine and Rehabilitation 2013;(1):53-55
Objective To observe the efficacy of bioelectric stimulation of the pelvic floor combined with acupuncture in treating detrusor urine weakness after transurethral resection of the prostate (TURP) in patients with prostate hyperplasia.Methods Forty-seven cases with detrusor urine weakness after TURP were randomly divided into an experimental group and a control group.All of the patients received routine bladder function training and medication.In addition,patients in the experimental group were treated with bioelectric stimulation of the pelvic floor and with acupuncture.The differences between the two groups were compared using the International Prostate Symptom Score (IPSS),maximum urine flow rate (MFR),average flow rate (AFR),detrusor pressure at peak flow (PdetQmax) and residual urine volume in the bladder.Results No significant difference was found between the two groups before treatment,but at two weeks after treatment MFR,AFR and PdetQmax were significantly higher in the experimental group than in the control group,and residual urine volume and IPSS were significantly lower.Conclusion Bioelectric stimulation of the pelvic floor combined with acupuncture is more effective than routine bladder function training and medication alone for alleviating detrusor urine weakness after TURP.
4.Advances in the study of natural small molecular antibody.
Acta Pharmaceutica Sinica 2012;47(10):1281-6
Small molecule antibodies are naturally existed and well functioned but not structurally related to the conventional antibodies. They are only composed of heavy protein chains or light chains, much smaller than common antibody. The first small molecule antibody, called Nanobody was engineered from heavy-chain antibodies found in camelids. Cartilaginous fishes also have heavy-chain antibodies (IgNAR, "immunoglobulin new antigen receptor"), from which single-domain antibodies called Vnar fragments can be obtained. In addition, free light chain (FLC) antibodies in human bodies are being developed as therapeutic and diagnostic agents. Comparing to intact antibodies, common advantages of small molecule antibodies are with better solubility, tissue penetration, stability towards heat and enzymes, and comparatively low production costs. This article reviews the structural characteristics and mechanism of action of the Nanobody, IgNAR and FLC.

China Pharmacy 2007;0(26):-
OBJECTIVE:To compare the efficacy and safety between caspofungin and fluconazole in the treatment of severe pulmonary fungal infection in intensive care unit. METHODS:36 patients with systemic fungal infections in intensive care unit were randomly assigned to receive caspofungin 50 mg?d-1 which was added into 250 mL normal saline and infused in no less than 1h for 14 days after initial dose of 70 mg(caspofungin group,n=18) or fluconazole 400 mg?d-1 for 14 days by iv gtt (fluconazole group,n=18). The curative efficacy and adverse events in the two groups were observed. RESULTS:The effective rate was 100.0% in caspofungin group versus 66.7% in fluconazole group. The incidence rates were 22.2% and 72.2%,respectively. There were significant differences in the overall effective rate between two groups(P

OBJECTIVE:To compare the efficacy and safety of linezolid vs.vancomycin in the treatment of MRSA-inducing ventilator-associated pneumonia in ICU.METHODS:In randomized controlled trials,54 patients with MRSA-inducing ventilator-associated pneumonia in ICU were randomly divided into 2 groups.Linezolid group (n=24) were administered with linezolid 600 mg every 12 h for 10 days,ivgtt.Vancomycin group (n=30) were given vancomycin 500 mg every 8h for 10 days ivgtt.Adverse events and the efficacy of two groups were investigated.RESULTS:Comparison results of linezolid group vs.vancomycin group were as follows:effective rates:100% vs.66.7%,MRSA eradication rates:87.5% vs.43.3%,adverse reactions rates:12.5% vs.13.3%.There were significant differences in the effective rates and MRSA eradication rates between two groups.CONCLUSION:The efficacy and safety of linezolid in the treatment of MRSA-inducing ventilator-associated pneumonia is superior to vancomycin.

Chinese Journal of Primary Medicine and Pharmacy 2006;0(07):-
Objective To evaluate the effect of probucol on endothelium-dependent vasodilatation(i,e.flow- mediated dilation,FMD) function of the old patients with isolated systolic hypertension.Methods In this single- blind study,a total of 64 old pariems with isolated systolic hypertension were randomized to receive conventional an- tihypertensive therapy and probucol (0.5g twice daily,group A,n=33) or receive conventional antihyperrensive therapy(group B,n=31) for 12 weeks.The levels of blood lipid were measured and vascular endothelial function was assessed in the brachial artery by high-resolution ultrasound technique in form of endothelium-dependent vasodi- latation before and after treatment.Results After 12-week treatment,the levels of TC,LDL-C and HDL-C in group A were significantly reduced compared with those before treatment(all P0.05).Flow-mediated dilatation parameters in both groups were obviously improved compared with those before treatment( P
