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.

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 observethe effect of continuous veno-venous hemofiltration (CVVH) on serum level of antibrain-antibody (ABAb) in patients with severe traumatic brain injury.Methods Thirtysix patients with severe traumatic brain injury were randomly divided into control group (19 patients) and CVVH group (17 patients).The control group accepted conventional treatment,the CVVH group accepted CVVH treatment additionally for 7 d.ELISA was used to measure serum level of ABAb at 1,3,5,7,14 d after treatment.The change of ABAb in serum of each group was observed.The scores of Glasgow coma scale (GCS) was assessed everyday.Results The level of ABAb in CVVH group was significantly lower than that in control group from the third day after treatment[the third day:(1.28 ± 0.25) kU/L vs.(1.33 ± 0.30) kU/L;the fifth day:(1.37 ±0.17) kU/L vs.(1.42 ±0.22) kU/L;the seventh day:(1.45 ±0.37) kU/L vs.(1.52 ± 0.35) kU/L;the fourteenth day:(1.49 ± 0.41) kU/L vs.(1.67 ± 0.39) kU/L,P ＜ 0.05 or ＜ 0.01].The scores of GCS in CVVH group was significantly higher than that in control group from the seventh day after treatment [the seventh day:(6.95 ± 1.24) scores vs.(5.74 ± 1.51) scores;the fourteenth day:(9.29 ± 1.76) scores vs.(7.22 ± 1.24) scores] (P ＜ 0.01).Conclusion CVVH can decrease the level of ABAb and improve the prognosis.

Objective To summarize and classify the CT manifestations of chest wall tuberculosis and to investigate the relationship between CT classification and clinical operation method.Methods CT data of 142cases was collected from patients that were confirmed by surgical pathology of chest wall tuberculosis.Bone algorithm reconstruction and volume rendring three-dimensional reconstruction were applied to observe ribs.Results Four types were classified according to the CT manifestations.Type Ⅰ:27 cases pleural tuberculoma,and all of which were conducted simple removal of lesions.Type Ⅱ:18 cases sternum or ribs tuberculosis,which were conducted surgical removal of the invaded frame and the surrounding lesions in caseous necrosis and all the tuberculous granuloma.Type Ⅲ:21 cases rib outboard tuberculosis,of which 12 cases were conducted simple removal of lesions and 9 cases removal of lesions and small segment of ribs.Type Ⅳ:76 cases hybrid,of which abscess excision plus rib resection in 65 cases and resection with chest wall abscess (muscle) between ribs and rib resection with padded muscle flap surgery in 11 cases.Conclusions CT can clearly show the location,size,scope of involvement of the chest wall tuberculosis,and selecting the preoperative surgical strategy based on CT classification can provide guidance for operation.

With the aging of the population,management of cancer in the elderly aged people represents a priority for health care.However,fewer evidence-based data are available to promote the treatment of these patients.Comprehensive geriatric assessment (CGA) is developed recently as a multi-disciplinary in-depth evaluation to assess life expectancy and risk of morbidity from cancer in elderly patients,which is helpful for physicians to develop a coordinated plan for cancer treatment and to provide appropriate interventions to decrease the risk of morbidity and mortality.

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.
