1.Progress of pathophysiological mechanism of angiotensin-converting enzyme 2 in treating pulmonary arterial ;hypertension
Chinese Critical Care Medicine 2016;28(6):569-572
Pulmonary arterial hypertension (PAH) is an incurable fatal disease, with the mechanism of imbalance of vascular contraction and relaxation which start as a series of pathophysiological reactions. Angiotensin-converting enzyme 2-angiotensin (1-7)-G protein-coupled receptor axis [ACE2-Ang(1-7)-Mas], an expanded vascular axis which is considered as new axis of renin-angiotensin system (RAS) is a negative regulator of the classical angiotensin-converting enzyme-angiotensin Ⅱ-angiotensin Ⅱ type 1 receptor axis (ACE-AngⅡ-AT1R), a contraction vessel, proliferation axis. A retrospective study concerning the pathophysiological mechanism of ACE2 in the treatment of PAH was done and found that ACE2-Ang-(1-7)-Mas axis could reduce PAH induced by monocrotaline (MCT) through declining the inflammatory cascade, improving endothelial dysfunction and regulating autonomic nerve, reduce PAH induced by hypoxia through inhibiting the proliferation of pulmonary artery smooth muscle cells and reduce PAH induced by congenital heart disease. Therefore, ACE2 may become a future drug of preventing and treating PAH.

Chinese Journal of Rehabilitation Theory and Practice 2014;20(11):1063-1067
Objective To investigate the serum lipoprotein (Lp) (a) level in patients with acute ischemic stroke and the prediction for short-term functional outcome. Methods The levels of serum Lp(a) were measured in 210 patients with acute ischemic stroke (within 24 h after onset) and 100 healthy people matched the gender and age. The patients were assessed with National Institutes of Health Stroke Scale (NIHSS) as admission, and modified Rankin Scale (mRS) as discharge. Results The median of Lp(a) was 325 mg/L (IQR: 180~545) in patients,significantly more than 148 mg/L (IQR: 69~265) in the normal controls (P<0.001). Level of serum Lp(a) was an independent variable for functional outcome (OR=1.004, 95%CI: 1.001~1.007, P<0.001) and death (OR=1.006, 95%CI: 1.001~1.008, P<0.001) in patients. In the receiver operating characteristic curve, the area under curve was more in the combined model [Lp(a) and NIHSS] than the NIHSS alone.Conclusion Serum Lp(a) increased in the in patients with acute ischemic stroke, and may predict the short-term outcome independently.
6.Optimization of Extraction Technology of Hyperici Perforate Herba, Coptidis Rhizoma, Schisandrae Chinensis Fructus, and Ziziphi Spinosae Semen forJinzao Yuanzhi Capsule by Orthogonal Test
Chinese Journal of Information on Traditional Chinese Medicine 2015;(1):91-94
Objective To optimize the extraction conditions of Hyperici Perforate Herba, Coptidis Rhizoma, Schisandrae Chinensis Fructus, and Ziziphi Spinosae Semen forJinzao Yuanzhi Capsule.Methods Hyperin extraction rate was set as index, and HPLC was used for determination. The extraction conditions of ethanol concentration, ethanol quantity, extraction time and other factors were studied with orthogonal test and comparative test.Results Ethanol concentration and extracting times were remarkable factors in the test. The optimum extraction technology forJinzao Yuanzhi Capsule was to reflux and extract the materials with 8 times of 70% ethanol for 2 times, reflux extraction for 1.5 hours, filtration. Then 6 times of 70% ethanol was added for 1.5 hours’ reflux, filtering, and merging extracted liquid.Conclusion The optimum extraction technology is reasonable and feasible.

Objective The purpose of this study was to investigate the effect of blood supply decrease on glycosaminoglycans(GAG)of the cartilage in the temporomandibular joint(TMJ) . Method Four rabbits were used as controls, and 16 rabbits were injected 5% sodirm morrhumate through carotid artery unilaterlally. All specimens were examimined histochemically. Result A reduction in alcian(AB) blue staining was observed after operation, a gradual increase in AB staining with blood supply restoration of TMJ tissue was observed. Conclusion The result suggests that the decrease in blood supply of the temporomnandibular jorint leads to the loss of GAG in the condylar cartilage, which may play an important role in pathogenesis of osteoarthrosis.

This study was aimed to mine correlation between the cause and traditional Chinese medicine ( TCM ) syndrome of polycystic ovary syndrome ( PCOS ) from different angles and at different levels . The study found
that the inherent laws of the cause and syndrome by the application of different statistical methods and data mining methods . The literature information database of PCOS was searched . And the Microsoft Office Excel and the Microsoft Office Access were used in the establishment o the database . And the SPSS17 . 0 was used as the statistical software . The Medisc-3S system was used as the mining tools to discover the rules between etiology and syndrome . The function of frequency statistics and complex networks were used to discover and summarize the TCM syndrome and treatment of PCOS . The TCM syndrome and treatment of PCOS were discov-ered and summarized according to the statistical results . And the results showed that three reasons of etiology and pathogenesis of PCOS contained kidney-deficiency , phlegm-dampness , and blood-stasis . The five types of TCM syndrome included spleen-kidney deficiency , kidney-deficiency and blood-stasis , spleen-deficiency and phlegm-dampness , kidney-deficiency and phlegm-dampness , kidney-deficiency and liver stagnation . It was concluded that the treatment should be mainly from kidney-tonification and assisted with blood-activation and phlegm-removing . The association rules and complex networks of data mining methods were applied in the lit-erature research of PCOS . The results provided literature references and statistical evidences for the phlegm-dampness accumulation in the uterus as the pathogenesis of PCOS , and the methods of kidney-tonification , blood-activation and phlegm-removing as the treatment principles .

The steroidal enzyme cytochrome P45017alpha catalyzes the conversion of progesterone and pregnenolone into androgens, androstenedione and dehydroepiandrosterone, respectively, the direct precursors of estrogens and testosterone. Dihydrotestosterone is the principal active androgen in the prostate, testosterone is also an active stimulant of the growth of prostatic cancer tissue. Inhibition of this enzyme as a mechanism for inhibiting androgen biosynthesis could be a worthwhile therapeutic strategy for the treatment of PCA. In this paper, four categories of steroidal inhibitors of cytochrome P45017alpha will be reviewed, a diverse range of steroidal inhibitors had been synthesized and shown to be potent inhibitors of P45017alpha.

Objective To observe the clinical effect of phloroglucinol combined with diazepam in prolonging the latency of primipara and the influence on the safety of mother and infant after medication .Methods A total of 180 cases with a naturally occurring post-partum latency≥8 h and no progress of patients in Weifang Tranditional Chinese Hospital from June 2015 to June 2016 in this study were divided into control group and observation group with 90 cases in each group.The observation group were treated with phloroglucinol combined with diazepam,the control group were treated with diazepam.Two groups appeared uterine inertia when the discretion of intravenous infusion of 0.5% oxytocin injection.Two groups were observed to 16h, still no progression of labor related to obstetric intervention.Observed of cervix big open situation,cervical opened time, cervical edema rate, cervical laceration rate, the rate of vaginal delivery, two hours postpartum hemorrhage, Apgar scores of newborns and the adverse reaction of medicine. Results The duration from drug administration to full dilation of cervix in obseve group was significantly shorter than the control group(P<0.05),the rate of cervical edema in the observation group was significantly lower than the control group(P<0.05), but no statistically difference in the cervical laceration.The the rate of vaginal delivery in observation group decreased significantly when compared with the control group ( P<0.05 ) , two hours postpartum hemorrhage and the Apgar scores of newborns had no significant differcences.Conclusion Puerpera latency prolonged application of phloroglucinol combined with diazepam can significantly speed up the cervix to open the time , and reduce cervical edema and improve vaginal delivery rate,and cervical laceration,two hours postpartum hemorrhage and neonatal complications had no effect.
