Journal of Chongqing Medical University 1986;0(04):-
Objective:To study the expression of Pleiotrophin and Midkine protein in endometrium of endometriosis and its clinical significance.Methods:Expressions of Pleiotrophin and Midkine protein were examined by immunohistochemical staining method in 30 endometrial samples of endometriosis(study group) and 29 endometrium of uterine fibroid(control group).Result:Pleiotrophin protein mainly expressed in the membrane and plasma of glandular epithelium of endometrium.Midkine protein mainly expressed in the plasma of grandular epithelium of endometrium and expressed in nuclei in some samples.The expression of Pleiotrophin and Midkine protein in endometriosis was significantly higher than that in the control group(P
2.Clinical Analysis of Pregnancy Outcome in 95 Cases with Preterm Premature Rupture of Membrane
Journal of Practical Obstetrics and Gynecology 2017;33(6):458-460
Objective:To investigate the risk factors of preterm premature ruPture of membrane(PPROM) and their pregnancy outcomes.Methods:The clinical data of 95 cases of patients with PPROM admitted and treated in our hospital from October 2013 to July 2016 were collected,which were divided into two groups,observation group(gestational week 28-33 +6 weeks) and control group(gestational week 34-36 +6 weeks).The risk factors of PPROM,delivery method and pregnancy outcomes were analyzed.Results:Genital tract infection was the main risk factor of PPROM(33.68%).of the incidences of cesarean delivery,neonatal asphyxia,neonatal infections and neonatal death in observation group were significantly higher than those of control group,the differences were statistically significant(P < 0.05).The intrauterine infection and puerperal infection rates of observation group of were higher than those of control group,but differences were not statistically significant (P > 0.05).Conclusions:Reproductive tract infections is the most important risk factor of PPROM.The purpose of active treatment including tocolytic therapy and prevention of infection for the patients with PPROM less than 34 weeks is to prolong the gestational weeks,to reduce the rate of neonatal complication,and to improve the pregnancy outcome.
5.Preparation and in vitro Transdermal Study of Zolmitriptan-Diclofenac Microemulsion
China Pharmacy 2017;28(13):1841-1844
OBJECTIVE:To prepare zolmitriptan-diclofenac microemulsion,and conduct quality evaluation and in vitro trans-dermal study. METHODS:Using solubility and microemulsion area in pseudo-ternary phase diagram as indexes,the types of oil phase and mixed emulsifier ratio of zolmitriptan-diclofenac microemulsion were screened;the microemulsion quality was inspected using particle size,Zeta potential,appearance and stability. HPLC was used to measure the contents of zolmitriptan and diclofenac. Transdermal diffusion test instrument was used,2 g microemulsion was smeared in cuticle of extracouporeal rats'skin,and cumula-tive transdermal rate in 24 h was determined. RESULTS:The microemulsion formulation was as follow as 10% oil phase(octanoic acid triglyceride),25% mixture emulgator [polysorbate 80-brij 97 (1:1)],8.3% propylene glycol and 25 mg zolmitriptan,1.25 mg diclofenac,and water adding to 100 mL. The average particle size of prepared microemulsion was(28.2±2.5)nm,Zeta poten-tial was(-3.25±0.33)mV,the appearance was rounding;the microemulsion showed no stratification or flocculation at room tem-perature after placed for 1 month. Contents of zolmitriptan and diclofenac were 0.248 mg/mL,12.46 mg/mL(n=3);24 h cumula-tive transdermal rates were 80%,75%. CONCLUSIONS:Zolmitriptan-diclofenac microemulsion is prepared,and its in vitro trans-dermal ability is good.
6.Diagnostic value of blue laser imaging combined with magnifying endoscopy for precancerous lesions and early gastric cancers
Chinese Journal of Digestive Endoscopy 2017;34(1):24-29
Objective To evaluate the diagnostic value of blue laser imaging( BLI) combined with magnifying endoscopy for precancerous lesions and early gastric cancers. Methods From September 2015 to May 2016, a total of 249 gastric lesions detected with conventional white light endoscopy ( WLE) on the basis of the assessment of mucosal shape and color were enrolled in this study. The pathological results were used as golden standard,and diagnostic accuracy rates of precancerous lesions or early cancers by white light magnification alone,BLI?contrast magnification and BLI?bright magnifier were determined according to the VS criteria. The concordance between endoscopic diagnosis and pathological diagnosis was evaluated through the agreement ( Kappa ) test, and diagnostic value was compared with McNemar paired Chi?square test. Results Pathological examination showed chronic gastritis in 149 lesions, intestinal metaplasia in 67, low grade intra?epithelial neoplasia in 8, and high grade intra?epithelial neoplasia or early cancer in 25. The concordance rates of lesions were 76?7% for white light magnification alone, 85?1% for BLI?contrast magnification, and 86?7% for BLI?bright magnification. Kappa values were 0?571, 0?730, and 0?760 respectively. For the screening of high grade intra?epithelial neoplasia or early cancer, the diagnostic sensitivities were 72?0%, 92?0%, and 92?0%, respectively, the specificities were 95?5%, 98?2%, and 99?1%,the consistencies were 93?2%,97?6%,98?4%,and the Kappa values were 0?642,0?871,and 0?911. In contrast to white light magnification alone,the concordance between endoscopic diagnosis and pathological diagnosis of BLI?contrast magnification and BLI?bright magnification was significantly higher(P<0?05).And in the diagnosis of high?grade intraepithelial neoplasia or early gastric cancer,the concordance between endoscopic diagnosis and pathological diagnosis of BLI?contrast magnification and BLI?bright magnification was higher than that of white light magnification alone( P<0?05) . Conclusion BLI combined with magnifying endoscopy may improve the diagnostic accuracy of early gastric cancer and precancerous lesions.

8.Non-traditional antiarrhythmic medicines for atrial fibrillation
Journal of China Pharmaceutical University 2010;41(1):86-90
Atrial fibrillation is the most common arrhythmia in clinical practice.However,the therapeutic effects of traditional antiarrhythmic medicines are far from satisfactory,because of the high rate of arrhythmia recurrence and the potential proarrhythmia effect.Recently,with the further investigation of the mechanisms that initiate and perpetuate atrial fibrillation,and the support of extensive data from clinical trials and animal experiments,thera-peutics based on anti-inflammation,antioxidation,regulation on renin-angiotensin-aldosterone system(RAAS)and gap junction may be new therapeutic targets for the treatment of arrhythmia.In this paper,the potential molecular mechanisms involved in these processes and several clinical trials about some non-traditional antiarrhythmic medi-cines were reviewed,in order to propose a new idea about the development of antiarrhythmic medicines.
