This article discusses the experience of professor SUN Wei-feng in diagnozing and treating PCOS(polycystic ovary syndrome) from four aspects:the cuase of the disease,the thought of treatmeat,the differentiation of syndrom,and the experience of treatment,combination of prescriptions.Professor SUN thinks that its pathology basis is deficiency of kidney and blood stasis,and points out that the method of tonifying kidney and promoting blood could be considered as the basic way of treat PCOS in TCM,the treatment cycle of the TCM is the important links to this disease,it should according with the different syndroms to use different methods on clinic.

AIM: To observe the pathological role of 3-nitrotynosine (3-NT) on Escherichia coli LPS-induced vascular hyporeactivity in rats and the therapeutic effect of antioxidants. METHODS: Forty male SD rats weighting from 200 g to 250 g were randomly divided into four groups: the control group (n=10); LPS shock group (n=10); uric acid-treated group (n=10); melatonin-treated group (n=10). 6 h after LPS shock, phenylephrine (0.5-2.5 ?g?kg -1) was applied intravenously to all groups and the percentage increase in MAP was detected, respectively. The concentration-response curve of aorta rings from all groups rats were obtained by cumulative addition of phenylephrine (PE), and PE E_ max, EC_ 50 were calculated. The concentrations of plasma malondialdehyde (MDA), nitrate/nitrite and 3-NT were assayed in all groups 6 h after LPS shock. RESULTS: The MAP level induced by PE significantly decreased to 54.60% in LPS shock rats compared with the control (P

Stathmin is a novel member of microtubule-destabilizing proteins that play a critical role in the regulation of the dynamic equilibrium of microtubules during different phases of the cell cycle.The overexpression of stathmin was found in different type of cancer.Inhibition of stathmin expression in malignant cells may interfere with their orderly progression through the cell cycle.Overexpression of stathmin can affect the action of antimicrotuble drugs by markedly decreasing binding of paclitaxel,and increasing binding of Vinca alkaloids.In addition,stathmin provides an attractive molecular target for cancer therapy.It may be possible to combine adenovirus-mediated anti-stathmin ribozyme therapy with a chemotherapeutic agent such as taxol to obtain a more potent antiproliferative and antitumor effect.

Objective To study the clinical and THR?gene mutation of two cases of pituitary thyroid hormone resistance. Methods The clinical data and peripheral blood samples of the patients and their family members were collected, and then DNA was isolated. PCR and direct sequencing techniques were performed to determine if there were mutations in their THR?gene. Results No mutation was found in exon 1-10. Conclusion Pathogenesis of sporadic pituitary resistance to thyroid hormone usually has no relation with mutation of THR?gene.

Objective To explore the effect of heroin dependence on the expression and the function of glucagon in islet A cells of rats.Methods The changes of numerical density on area of A cells and level of plasma glucagon of heroin-dependent rats were investigated by means of the immunohistochemical SABC method,image analysis and radioimmunoassay(RIA).Results As compared with SCG and NCG,it was observed that the number of Glu-IR positive cells increased and the intensity of immunohistochemical staining enhanced in the heroin-dependent groups.The result of image analysis showed that the numerical density on area of A cell apparently increased in the 38-day heroin-dependent group(P

Focal adhesion kinase (FAK) is a non-receptor protein tyrosine kinase (PTK) that can localize indirectly to sites of clustering integrin family of heterodimeric receptors. As an important structure and signaling molecule in the adhesive complexes, which are large and stable referred as ‘focal adhesions’ or relatively small and transient within filopodia and lamellipodia named ‘focal complexes’, FAK is closely related with cell death, proliferation and migration. In this review, we discuss the function of FAK in the regulation of endothelial cell migration based on current data.

Objective To investigate the effects of antioxidant on the gene expression of ?1-adrenergic receptors (AR) during endotoxic shock. Methods Forty male SD rats weighing 200-250 g were anesthetized with intraperitoneal (i.p.) pentobarbital. The animals kept spontaneous breathing. Femoral artery and vein were cannulated for BP monitoring and drug administration. The animals were randomly divided into 5 groups ( n = 8 each) : (1) control group; (2) LPS group received IPS 15 mg?kg-1 i.v. ; (3) LPS + propofol group received at 1h after LPS a bolus of propofol 10mg?kg-1 i.v. followed by continuous infusion of propofol at 10 mg?kg-1?h-1; (4) LPS + uric acid (UA) group received uric acid 200 mg i.p. 1 h after LPS and (5) LPS + melatonin (MLT) group received MLT 10 mg?kg-1 i.p. 1h after LPS. The animals were killed at 6 h after LPS. Total RNA was extracted from the heart, aorta, vein, lung, liver and kidney. ?1A-,?1B-,?1D- AR mRNA and ?-actin mRNA were measured using reverse transcription polymerase chain reaction (RT-PCR) .Results The expression of ?1A-AR and ?1B-AR mRNA in all the organs and the ?1D-AR mRNA expression in aorta, liver, lung and kidney were strongly down-regulated in LPS group. In group 3 (LPS + propofol) the expression of ?1A-AR mRNA in the lung and kidney, the ?1B-AR mRNA expression in all of the organs and ?1D-AR mRNA expression in aorta, liver, lung and kidney were significantly increased as compared with LPS group. There was no significant difference in ?1-AR mRNA expression between LPS group and LPS + MLT group. The expression of ?1A-AR mRNA in kidney, the ?1B-AR mRNA expression in all of the organs except the lung and the ?1D-AR mRNA expression in aorta, liver, lung and kidney were significantly higher in LPS + UA group than in LPS group. Conclusion Circulatory failure induced by endotoxic shock is related to the down-regulation of ?1-AR gene expression. The therapeutic effects of antioxidant on the endotoxic shock is partly due to up-regulation of ?1-AR gene expression.

AIM: To observe the effect of heat shock protein 70(HSP70) expression induced by glutamine on Escherichia coli lipopolysaccharides(LPS)-induced vascular hyporeactivity in rats.METHODS: Twenty four healthy male Sprague-Dawley rats were randomly divided into: the control group (n=8); LPS shock group (n=8); glutamine(Gln) treated group (Gln 0.75 g?kg-1 iv, n=8). 6 h after LPS shock, phenylephrine (PE, 0.5-2.5 ?g?kg-1 ) was applied intravenously to all groups and the percentage increase in mean arterial pressure(MAP) was detected, respectively. The concentration-response curves of aorta rings were obtained by cumulative addition of phenylephrine (PE), and PE Emax, EC50 were calculated. The blood concentration of malondialdehyde (MDA), TNF-? and IL-6 were assayed in all groups 30 min and 360 min after LPS shock, respectively. The expressions of HSP70 from heart and aorta were also assayed after 6 h LPS shock.RESULTS: The MAP level induced by PE significantly decreased by 51.4% in LPS shock group compared with the control (P

Objective: To evaluate the clinical efficacy and safety of ticagrelor in the patients with acute coronary syndrome ( ACS) . Methods:A retrospective study was applied to investigate the ACS patients treated with ticagrelor in our hospital from July to December in 2015. The basic information of patients, drug administration, platelet aggregation induced by ADP, major adverse cardio-vascular events ( cardiac death,nonfatal myocardial infarction,target vessel revascularization and stent thrombosis) , and adverse drug reactions ( ADR) were recorded. The incidence of end point events was calculated and the change of platelet aggregation induced by ADP before and after the drug administration was analyzed by SPSS statistical software. Results:A total of 161 patients were collected. The incidence of cardiovascular adverse events was 1. 2%, while the incidence of adverse drug reactions was 30. 4% including bleeding (15. 5%) without severe bleeding events and dyspnea (10. 6%) with 3 severe ones. The platelet aggregation rate before and after the ticagrelor treatment respectively was (54. 96 ± 14. 654)%and(24. 37 ± 13. 183)% in 122 patients with low reaction to clopidogrel( P<0. 01). Conclusion:Ticagrelor at the recommended dose can further reduce the platelet aggregation induced by ADP. In spite of high incidence of ADR, ticagrelor has slight ADR with good tolerance.

Objective To discuss the relationship between the infection of respiratory viruses and secretory otitis media(SOM). Methods The alkaline phosphatase anti-alkaline phosphatase(APAAP) bridged rapid diagnosis was used to detect the antigens of the common respiratory viruses in middle ear effusions(MEES). Results One or more kinds of antigens of respiratory viruses were detected in 73.9% MEES. Six kinds of antigens were detected in three patients' MEES at the same time. There were significant differences positive rates of the antigens of respiratory viruses in MEES with or without a cold history(P
