Objective To observe the effect of Zhuyun Capsule(Pregnant-promoting Capsule)on serum sex hormone and expres- sion of ovarian cytokine of polycystic ovary syndrome(PCOS)rats.Methods Progestogen plus human chorionic gonadotrophin (HCG)was adopted to make PCOS rat models.Totally 40 SD rats were randomized into control group,PCOS model group,Zhuyun Capsule group,and clomiphene citrate group with 10 in each.Radioimmune assay(RIA)was used to measure the sex hormone and immunohistochemical test was done to measure the expression of tumor necrosis factor-?(TNF-?)of ovarian tissue,insulin-like growth factors-1(IGF-1),and leukemia inhibitory factor(LIF)to analyze the relations among these factors.Results Zhuyun Capsule could reduce greatly serum testosterone(T)and luteinizing hormone(LH),decrease expression of TNF-?and IGF-1,but increase expres- sion of LIF.Conclusion Zhuyun Capsule could regulate endocrine function and expression of ovarian cytokine to improve gonad func- tions of PCOS rats and to promote the maturation of follicle and ovulation.

AIM: To investigate the early changes of retinal function in diabetic patients detected by multifocal electroretinogram (mfERG).METHODS: The first-order kernel responses of mfERG were recorded from eyes of 33 normal control subjects,63 diabetic patients without retinopathy and 43 diabetic patients with background retinopathy. The response densities and implicit times of N1 and P1 were compared among the control, diabetic patients without retinopathy and diabetic patients with retinopathy.RESULTS: The response densities of N1 and P1 in central 3 rings were reduced significantly in diabetic eyes with and without retinopathy. And the implicit times of N1 and P1 were delayed significantly only in diabetic eyes with retinopathy.CONCLUSION: mfERG can detect the early changes of retinal function quantitatively in diabetic patients. Analysis of response densities and implicit times of N1 and P1 can reflect the progress of local retinal dysfunction in diabetes.

Salvia miltiorrhiza is a traditional Chinese medicine (TCM) and is widely used as a clinically medication for its efficiency in treating cardiovascular disease. Due to TCM is a comprehensive system, the mechanism of S. miltiorrhiza treating cardiovascular disease through integrated multiple pathways are still unclear in some aspects. With the rapid progress of bioinformatics and systems biology, network pharmacology is considered as a promising approach toward reveal the underlying complex relationship between an herb and the disease. In order to discover the mechanism of S. miltiorrhiza treating cardiovascular disease systematically, we use the auxiliary mechanism elucidation system for Chinese medicine, built up a molecule interaction network on the active component targets of S. miltiorrhiza and the therapeutic targets of cardiovascular disease to offer an opportunity for deep understanding the mechanism of S. miltiorrhiza treating cardiovascular disease from the perspective of network pharmacology. The results showed that S. miltiorrhiza treating cardiovascular disease through ten pathways as follows: improve lipid metabolism, anti-inflammation, regulate blood pressure, negatively regulates blood coagulation factor and antithrombotic, regulate cell proliferation, anti-stress injury, promoting angiogenesis, inhibited apoptosis, adjust vascular systolic and diastolic, promoting wound repair. The results of this paper provide theoretical guidance for the development of new drugs to treat cardiovascular disease and the discovery of new drugs through component compatibility.

Objective To explore the technique of massive facial scar revision. Methods All 12 patients in the group were treated with expanded deltopectoral skin flap. In the primary surgery, expander was implanted underneath deltopectoral flap region through an incision inferior to the clavi-cle. The skin perforators of transverse cervical artery and thoracoacromial artery were ligated during surgery, and the internal thoracic artery was carefully preserved. After the deltopectoral skin flap was fully expanded, the second surgery was performed and the facial scar was released and the normal ana-tomic position of eyes, nose and month was restored. The deltopectoral skin flap was planed according to the size of the defect. The excised facial scar was converted to the flap pedicle and a hinge-like con-nection was formed. The flap was delayed and three weeks after the second surgery, the pedicle was divided. The flap from the pedicle was applied for the mental region scar revision. Results Unilateral or bilateral dehopectoral skin flaps were employed for the repair of extensive facial scar in 12 patients. Satisfactory results were achieved in all these patients. Conclusion Expanded deltopectoral skin flap is a good technique for the repair of extensive facial scar.

OBJECTIVETo investigate the therapeutic effect of scalp expanded flap combined with JPL hair removal for large area scar on forehead.

METHODSFrom Jul. 2010 to Nov. 2012, 9 cases with large area scar on forehead received treatment of adjacent scalp expanded flap combined with JPL hair removal. One the first stage, the expander was implanted under the scalp near the forehead scar, followed hy expansion process. When the expansion was completed, the expanded flap was transferred to cover the wound after scar excision. 10 days after flap transposition, the forehead hair line was designed and extra hair on flap underwent JPL hair removal. After 3-5 treatments, the hair on flap was almost removed.

RESULTSAll the scalp flaps survived completely. JPL hair removal had exact effect. The patients were followed up for 5-11 months. The hair density on the flap decreased hy more than 90%. The flap had a good match with surrounding facial skin in color, texture and thickness. The reconstructed forehead hair line was satisfactory.

CONCLUSIONSIt is a good option to reconstruct large area scar on forehead with scalp expanded flap comhined with IPL hair removal.

Objective To investigate whether fasting obestatin level is different in patients with impaired glucose tolerance or type 2 diabetes, and to explore the association between obestatin and lipid metabolism. Methods Eighty-four subjects without known diabetes were divided into three groups: normal glucose tolerance(NGT), impaired glucose tolerance (IGT) and type 2 diabetes (DM) Plasma obestatin levels were measured with a radioimmunoassay. The relationship between fasting obestatin levels and metabolic parameters was also analyzed. Results Fasting obestatin levels were lower in DM group [(2.82±0.78)ng/ml] and IGT group [(3.25±0.29)ng/ml] than in NGT group[(3.55±0.57) ng/ml, P＜0.01]. Triglycerides and low density lipoprotein cholesterol levels gradually increased among the three groups (P＜0.05). Multiple linear regression analysis revealed fasting obestatin level was independently associated with waist-to-hip ratio, triglyeride and low density lipoprotein cholesterol. The regression equation was obestatin=6.953-3.412×W/H-0.175×TG-0.123×LDL-C. Conclusions The decreased obestatin may be associated with IGR and T2DM, and obestatin level may be associated with lipid metabolism.
