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

Objective To compare the neurotoxic effects of intratheeal ropivacaine and bupivacaine on the spinal cord in rats.Methods Female SD rats weighing 240-330 g were used in this study.Catheters(PE 10 tubing)were inserted through an incision in the cisternal membrane and advanced caudad until the tip of the catheter reached the lumbar spinal level according to the technique described by Yaksh and Rudy.Fifty-four successfully catheterized rats were randomly assigned tO one of 3 groups(n=18 each):group Ⅰ received normal saline 30μlIT(NS);groupⅡ received 2%bupivacaine 20μl IT(BU)and group Ⅲ 2.7%ropivacaine 20μl IT (RO).Degree of motor block was assessed and scored(0=no block,2=inability to flex the hind limb)before (T1,baseline)and at 10,20,30,60 and 120 min(T2-6)after IT injection.On the 4th day after IT injection specimens were obtained from lumbar spinal cord for microscopic examination.Results The motor block score was significantly higher in group BU and RO than in group NS(P＜0.05),and the tissue damage was severe in group BU and RO.The motor block scores were significantly higher at T2 than at T3-6 in beth group BU and RO(P＜0.05).There Was no significant difference in motor block score at T2 between groups BU and RO but the motor block scores were significantly lower at T3-5 in group RO than in group BU(P＜0.05).The tissue damage was Severer in group RO than in group BU(P＜0.05).Conclusion Intrathecal 2.7% ropivacaine is more toxic to the spinal cord than intrathecal 2%bupivacaine in rats.

Genetic susceptibility of lung cancer plays an important role in genesis of lung cancer.Studies find that tumor necrosis factor α(TNF-α)is significantly up-regulated in lung cancer patients.It may be correlated with the TNF-α polymorphism in its promoter region which affects its transcription and expression.TNF-α polymorphisms may be an important genetic marker for susceptibility of lung cancer.

Objective To investigate the role of protein O-linked N-acetyl-glucosamine (O-GlcNAc) modification in glutamine-induced improvement in the vascular hyporeactivity in rats with septic shock.Methods Thirty-two adult male Sprague-Dawley rats,aged 2-3 months,weighing 250-300 g,were randomly divided into 4 groups (n =8 each):sham operation group (S group); septic shock group (C group); glutamine group (G group) ; alloxan group (A group).Septic shock was induced by cecal ligation and puncture (CLP).In G and A groups,glutamine 0.75 g/kg was infused intravenously over 30 min at 1 h before CLP,and in addition alloxan 90 mg/kg was infused intraperitoneally in A group.Phenylephrine (PE) 0.5,1.0,2.0,and 2.5 μg/kg was injected intravenously at 20 min intervals at 6 h after CLP and the percentage increase in mean arterial pressure (MAP) was calculated.The thoracic aorta rings were isolated to perform the isolated vascular tension experiment.The concentration-response curve of PE was obtained in tension experiments,and the PE maximum efficacy (Emas) and median effective dose ( EC50 ) were calculated.The expression of O-GlcNAc modification and iNOS content in the thoracic aorta were detected in all groups.Blood samples were taken to determine the serum concentration of NO.Results Compared with S group,the percentage increase in MAP and Emax were significantly decreased,while the EC50,serum concentration of NO,and expression of O-GlcNAc modification and iNOS content in thoracic aorta were significantly increased in C,G and A groups ( P ＜ 0.05).Compared with C group,the expression of O-GlcNAc modification in the thoracic aorta was significantly increased,and EC50 was significantly decreased in G group,and the percentage increase in MAP and Emax were significantly increased,while the serum concentration of NO,and content of iNOS in the thoracic aorta were significantly decreased in G and A groups ( P ＜ 0.05).Compared with G group,the EC50,serum concentration of NO,and content of iNOS in the thoracic aorta were significantly increased,while the percentage increase in MAP,Emax and expression of O-GlcNAc modification in the thoracic aorta were significantly decreased ( P ＜ 0.05 ).Conclusion Glutamine improves the vascular hyporeactivity through increasing the level of protein O-GlcNAc modification in rats with septic shock.

Objective To explore the curative effects of color Doppter ultrasound guided interventional therapy in pelvic cyst. Methods From July 2006 to June 2008,the color Doppler ultrasound guided transabdominal or transvaginal puncture was performed in 34 pelvic cysts among 32 diagnosed cases,absolute alcohol was injected into the cysts for sclerotherapy.Results Among 34 cysts,the treatment only failed in one cyst of one case because of the over ropy hydatid fluid,which was hard to be aspirated.All of the cases were followed up for three months.Twenty-seven cysts were cured after the first treatment,the cure rate was 79.4%(27/34).The maximum diameter of other 4 cysts decreased more than 1/2.The effective rate was 91.2%(31/34) after the first puncture.Finally,33 cases showed curative effect after the puncture therapy,the total effective rate was 97.1%(33/34).No serious complications were observed.Conclusion This therapy is a simple,accurately,safe and effective treatment for many indications.It's worthy to be recommended in the therapy of pelvic cyst.

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.
