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

OBJECTIVETo observe the lower gastrointestinal mesenchymal tumors CT virtual endoscopy and pathology, and to explore its possible mechanism.

METHODSSelect 80 patients suspected colon gastroenterology treat in the hospital gastroenterology department, randomly divided into experimental group and control group, 40 cases in experimental group were given CT virtual endoscopy and pathological check, the control group received conventional colonoscopy and pathological check, and all the results compared with the pathological results.

RESULTSCompared with the pathological test results, consistent rate with the experimental group reached 94.73%, the same rate was 92.85% in control group. The difference was not statistically significant (P > 0.05).

CONCLUSIONSCT virtual endoscopy can quickly image and draw detailed information, and can improve the sensitivity and specificity of cancer diagnosis greatly. Clinically, CT virtual endoscopy have the same function as colonoscopy, can replace colonoscopy, can be important complement of electronic colonoscopy by those who cannot tolerate electronic colonoscopy or have contraindications. Its value is worth taking a step forward in-depth study.

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 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

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.

Objective To observe the change of serum anti-brain antibodies after cardiopulmonary resuscitation,and investigate the clinical significance.Methods A total of 27 cases of cardiopulmonary resuscitation after cardiac arrest patients with success and survival more than 12 weeks were divided into two groups according to Glasgow Coma Scale (GCS) score:mild and moderate group with GCS score ≥ 8 scores (12 cases) and severe group with GCS score≤7 scores (15 cases).The serum anti-brain antibody levels at 3,7 days and 2,3,4,12 weeks after recovered in the spontaneous circulation (ROSC) was compared between two groups,and compared with control group (15 cases of healthy persons).Results The serum anti-brain antibody levels at 3,7 days and 2,3,4,12 weeks after ROSC were significantly higher than those in control group [(1.34 ± 0.23),(1.30 ± 0.27) kU/L vs.(0.28 ± 0.05) kU/L,(1.38 ± 0.33),(1.44 ± 0.30) kU/L vs.(0.28 ±0.05) kU/L,(1.44 ±0.31),(1.51 ±0.33) kU/L vs.(0.28 ±0.05) kU/L,(1.53 ±0.27),(1.67 ±0.36) kU/L vs.(0.28 ±0.05) kU/L,(1.72 ±0.25),(1.93 ±0.44) kU/L vs.(0.28 ±0.05) kU/L,(1.98 ±0.45),(2.15 ±0.52) kU/L vs.(0.28 ±0.05) kU/L],and there were significant differences (P＜ 0.01).The serum anti-brain antibody levels in severe group were significantly higher than those in mild and moderate group,and there were significnat differences (P ＜ 0.05).Conclusions The serum anti-brain antibody levels after cardiopulmonary resuscitation rise significantly.Anti-brain antibody may be used as a biochemistry marker to judge degree and prognosis of brain injury with patients after cardiopulmonary resuscitation.
