1.Study progress of methicillin-resistant Staphylococcus aureus resistance
Chinese Journal of Applied Clinical Pediatrics 2016;(4):259-262,263
Staphylococcus aureus is one of the common cause of respiratory tract infections in children.Methi-cillin -resistant staphylococcusaureus was reported in 1 960s,then the resistance of other drugs were found in recent years,which leading to many problems in the clinical treatment.Clinician have to master the resistance trend and mechanism of this bacteria and decrease the speed of resistance as much as possible.
2.Correlation of p53 expression with triple negative breast cancer and its prognosis:a meta analysis
Journal of Clinical Surgery 2015;(4):293-296
Objective To evaluate the expression of p53 in triple negative breast cancer( TNBC) and its impact on the prognosis of TNBC systematically. Methods Documents published on PubMed, Medline,CNKI,CNKI,Wanfang data,and VIP data were screened for relative researches. Two reviewers filtered,extracted and assessed the literatures according to the inclusion criteria and exclusion criteria. The meta analysis was conducted by using RevMan5. 0 software. Result A total 13 trails were included,con-taining 11 Chinese documents and 2 English documents. The meta analysis showed that p53 is significantly expressed in TNBC[OR=2. 02,95%CI(1. 28,3. 19)]. TNBC patients with positive p53 expression had higher rates in lymph node metastasis[OR=2. 02,95%CI(1. 28,3. 19)],recurrence[OR=3. 39,95%CI(1.45,7. 90)],metastasis[OR =2. 65(1. 36,5. 18)],disease-free survival[OR =0. 29(0. 18, 0. 47)]and overall survival[OR=0. 29(0. 18,0. 47)]than patients with negative p53 expression. Con-clusion p53 is overexpressed in TNBC,which plays a certain role in guiding the clinical prognosis of TN-BC. It can be regarded as an independent factor to evaluate the prognosis of TNBC,and a therapeutic tar-get in further studies.

4.Determination of camphor,menthol,synthetic bornel and the wintergreen oil in Shexiang Zhuanggu Plaster by GC
Chinese Traditional Patent Medicine 1992;0(02):-
AIM:To study the method of determing camphor, menthol, synthetic bornel and the wintergreen oil contents in Shexiang Zhunggu Plaster. METHODS: Gas phase chromatogram was used to determine contents of camphor, menthol, synthetic bornel and the wintergreen oil in Shexiang Zhuanggu Plaster. The chromatogram condition consisted of the capillary vessel column(PEG-20M, 30 m?0.32 mm?0.25 ?m). The temperature programing rose from 100 ?C to 130 ?C by 5 ?C /minute, then 30 ?C /minute to 200 ?C , lasting 2 minutes in the end. The temperature of the entrance of the capillary vessel column: at 220 ?C , temperature of the detector was 240 ?C ; N_2: 5 mL/minute, H_2: 45 mL/minute, Air: 450 mL/minute; sample quantity was 0.2 ?L. RESULTS: Under certain chromatogram condition, there was linear relation among the camphor, menthol, synthetic bornel and the wintergreen oil and the peak area in the scope of 0.027 38 mg/mL-0.438 08 mg/mL, 0.041 15 mg/mL-0.658 4 mg/mL, 0.033 38 mg/mL-0.534 1 mg/mL, 0.042 15 mg/mL-0.674 4 mg/mL, respectively. The average recoveries were 98.37%, 99.76%, 98.80% and 97.61%, respectively. RSD were 1.7%, 1.8%, 0.96% and 1.5%, respectively. CONCLUSION: This experiment provides an accurate and reliable method to control the quality of Shexiang Zhuanggu Plaster.

Objective To assess whether the T~ -786 →C mutation of endothelial nitric oxide synthase (eNOS) gene is associated with endothelial dysfunction in type 2 diabetes. Methods A total of 162 type 2 diabetic men without angiopathy were studied. PCR/alleles-specific oligonucleotide (ASO) probes were used to analyse the T~ -786 →C mutation of eNOS gene, and high resolution ultrasound was used to measure endothelium-dependent arterial dilation (EDD). Results The EDD among subjects with T/C or C/C was 3.73%?0.50%, which was significantly lower than that in subjects with T/T(4.15%?0.49%)(P

Objective To investigate the expression of ERCC1 in smoking patients with advanced non-small cell lung cancer(NSCLC) and its relationship with clinical features and prognosis.Methods The expression of ERCC1 was detected in 96 patients with advanced NSCLC by PCR assay.The clinicopathologic factors, treatment effect and survival time were observed.Results The expression of ERCC1 was related to smoking index(P=0.029), but it was not related to other clinicopathological factors.The patients with low expression of ERCC1 had better response rate and median survival time when compared to those with high expression patients.The difference was statistically significant(P=0.001,P<0.01).Conclusion ERCC1 expression is associated with smoking index and the patients with low expression of ERCC1 shows higher chemotherapy efficiency and longer median survival than patients with high expression, which indicates that detection of ERCC1 may be a useful parameter in evaluating the therapeutic effect and prognosis of smoking patients with advanced NSCLC.

Vascular endothelial growth factor (VEGF),platelet derived growth factor (PDGF) and complements play key roles in the pathogenesis of age-related macular degeneration (AMD).Pegaptanib,the first therapeutic aptamer against VEGF165,has been approved by the Food and Drug Administration (FDA) of US for the treatment of exudative AMD.Another two aptamers El0030 and ARC1905,each target PDGF-B and complement C5 respectively,are undergoing clinical trials.Recent trends to treat AMD are combined therapies targeting multiple key molecules in the pathogenesis of AMD;aptamers against multiple targets may become the preferred drug for AMD.

Objective To explore the hemostatic value of performed Microporous polysaccharide hemosph-eres in marginal placenta previa caesarean section,and assess the suitability of the application in primary hospitals. Methods 70 patients with marginal placenta previa were chosen,who regularly antenatal examined in Guangzhou Women and Children's Medical Center from November 2013 to October 2015,and they were randomly divided into two groups:research group(35 patients were performed haemostatics)and control group(35 patients were not performed haemostatics).Results The research group was obviously succeeded in the hemostasis time[(22.8 ±6.2)min vs (11.1 ±5.6)min;t =3.26,P <0.05],local suture[(4.6 ±1.5)times vs (1.9 ±0.7)times;t =3.87,P <0.05], 2h amount of bleeding[(685.4 ±126.7)mL vs (460.1 ±89.3)mL;t =4.66,P <0.05],24h amount of bleeding [(972.0 ±203.5)mL vs (632.3 ±107.1)mL;t =5.19,P <0.05]and failure rate(17.1% vs 2.9%,χ2 =3.96, P <0.05)than those in the control group.There were no significant differences between the two groups in postopera-tive disease rate,puerperal infection rate,the incidence rate of uterine involution,intrauterine adhesions,thrombosis. Conclusion The hemostatic effect is remarkable of Microporous polysaccharide hemospheres used in marginal placenta previa during caesarean section.It works quickly,easily,with little side effects,and is so suitable for promo-tion in primary hospitals.
