Chinese Journal of Dermatology 2001;34(3):175-177
Objective To investigate the antimicrobial susceptibility of Neisseria gonorrhoeae isolated from 10 cities of China, and to provide reference for the formulation of treatment guideline and making control strategy. Methods Agar dilution was used to detect antimicrobial susceptibility and acidometric method for PPNG testing. Results A total of 3186 gonococcal isolates were tested from 1993 to 1998. The resistant rate for penicillin was 66.70% . PPNG isolates accounted for 8.14% . Tetracycline- resistant isolates accounted for 93.02% , and high level tetracycline- resistant isolates (TRNG) accounted for 4.65% . The resistant rate for ciprofloxacin was also high (34.25% ). The resistant rates for spectinomycin and ceftriaxone were 0.44% and 0.57% respectively. Conclusions The gonococcal isolates are highly resistant to penicillin, tetracycline, and ciprofloxacin, while still sensitive to spectinomycin and ceftriaxone. These results suggest that the present treatment for gonorrhea can still be used.

Objective To explore the clinical signifcance of changes of serum Ang Ⅱ,hs-CRP and BNP levels and the relationship with atrial fibrillation(AF),and the risk factors of AF recurrence.Methods 100 patients with AF were selected in this study,and they were divided into two groups:paroxysmal atrial fibrillation group (n =54),durative atrial fibrillation group(n =46),and 50 healthy subjects were selected as control.The levels of serum Ang Ⅱ,BNP were detected by radioimmunoassay,and hs-CRP was detected by immunoturbidimetry.Results The levels of Ang Ⅱ,hs-CRP and BNP in atrial fibrillation patients were significantly increased as compared to control group (P < 0.01).The levels of Ang Ⅱ,hs-CRP in the durative atrial fibrillation group were higher than those in the paroxysmal atrial fibrillation group.The levels of serum Ang Ⅱ,hs-CRP were positively correlated with serum BNP level (r =0.563,0.678,all P <0.01).The level of serum Ang Ⅱ was positively correlated with serum hs-CRP level(r =0.626,P < 0.01).Multiple logistic regression analysis revealed that hs-CRP and BNP were the important risk factors of atrial fibrillation recurrence[OR value =2.42,95% CI(1.84 ~ 5.26) ;OR value =2.14,95% CI(1.37 ~.86)].Conclusion The serum AngⅡ,hs-CRP and BNP may play important roles in the development of AF.hs-CRP and BNP may be the independent risk factors of AF.The detection of hs-CRP and BNP may be related to recurrence prognosis in patients with AF.
8.The progress of targeted therapy in locally advanced head and neck squamous cell carcinomas
China Oncology 2013;(12):949-953
Multi-disciplinary modality treatment is the optimal therapeutic strategy for locally advanced squamous cell carcinoma of head and neck (SCCHN). Recently, molecular targeted agents have been tested in this setting. Epithelial growth factor receptor (EGFR) is the major therapeutic target because of its universally high expression in SCCHN. As a human-mouse chimeric monoclonal antibody, cetuximab is the only molecular targeted agent approved in SCCHN. As compared with radiotherapy alone, radiotherapy in combination with cetuximab was proved to improve progression-free and overall survival in patients with locally advanced SCCHN. However, randomized comparison between radiotherapy plus cetuximab and conventional concurrent chemoradiotherapy (CCRT) is limited in term of efficacy and toxicity. Although RTOG 0522 study demonstrated it is ineffective to combine cetuximab with CCRT, the optimal chemotherapy agent partner with cetuximab warrants further investigation. For other anti-EGFR inhibitors, how to wisely design pertinent clinical studies based on available evidence is the key for success.

10.Challenges in Drug Discovery for Thiazolidinedione Substitute.
Acta Pharmaceutica Sinica 2011;1(3):137-142
Thiazolidinedione (TZD) is a powerful insulin sensitizer in the treatment of type 2 diabetes. It acts as a ligand to the nuclear receptor PPARγ (peroxisome proliferator-activated receptor-gamma) and induces transcription of PPARγ responsive genes. TZD controls lipid synthesis and storage in adipose tissue, liver and many other tissues through PPARγ. Derivatives of TZD, such as rosiglitazone (Avandia) and pioglitazone (Actos), are more powerful than metformin or berberine in insulin sensitization. Although they have common side effects such as weight gain and edema, these did not influence the side effects in general. However, recent findings of risk for congestive heart failure and bladder cancer have indeed significantly impaired their future in many countries. European countries have prohibited those drugs and in 2011, US will terminate application of rosiglitazone in clinics and hospitals. The multiple country actions may mark the end of TZD era. As a result, there is a strong demand for identification of TZD substitute in the treatment of type 2 diabetes. In this regard, literature about PPARγ ligands and potential TZD substitute are reviewed in this article. Histone deacetylase (HDAC) inhibitor is emphasized as a new class of insulin sensitizer here. Regulators of SIRT1, CREB, NO, p38, ERK and Cdk5 are discussed in the activation of PPARγ.
