OBJECTIVETo Study the effect of anti-aging and its mechanism of total saponins of Wu-He Dipsacus asper on skin of mice-aging model.

METHODSForty-eight mice were randomly divided into blank control group, model group, low-Dipsacus group, medium-Dipsacus group, high-Dipsacus group and positive control group( n = 8) . The mouse model of skin aging was established by nape subcutaneous injection of 5% D-galactose (0.025 mL/(g · d)), the mouse of low-Dipsacus group, medium-Dipsacus group, high-Dipsacus group were administered with total saponins of Wu-He Dipsacus asper (50 ml/(kg · d), 100 mL/(kg · d), 200 mL/(kg · d)), the mice of the positive control group were administered with vitamin E(50 mg/(kg · d)) for 42 d. The content of hydroxyproline (HYP) and lipofuscin (LF) were measured in skin of each group mice, the activity of catalase (CAT) glutathione peroxidase ( GSH-Px) superoxide dismutase (SOD) and the content of malondi- aldehyde (MDA) were determined in serum and skin of each group mice.

RESULTSCompared with blank control group, the content of HYP decreased significantly and the content of LF increased significantly in skin, the activities of CAT, GSH-Px and SOD decreased significantly and the content of MDA increased significantly in serum and skin of model group; Compared with model group, the content of HYP increased significantly and the content of LF decreased significantly in skin, the activities of CAT, GSH-Px and SOD enhanced significantly and the con- tent of MDA decreased significantly in serum and skin of low-Dipsacus group, medium-Dipsacus group, high-Dipsacus group and positive control group; Compared with low-Dipsacus group, the content of HYP increased significantly and the content of LF decreased significantly in skin, the activities of CAT, GSH-Px and SOD enhanced significantly and the content of MDA decreased significantly in serum and skin of high-Dipsacus group and positive control group; The activity of SOD in serum and skin had a significant positive correlation with the content of HYP, and a significant negative correlation with LF in skin.

CONCLUSIONTotal saponins of Wu-He Dipsacus asper have obvious effect of anti-agng on skin of mouse-aging model , its mechanism is closely related to oxidative damage.

Objective To explore the effect of the simvastatin administration on the expression of connective tissue growth factor （CTGF） in fihrotic lungs of rats. Methods The cats were treated with single intratracheal instillation of bleomycin （BLM） or instillation of the same volume of normal saline （NS） as a control. The administration of simvastatin（20 mg/kg）began once a day immediately or 7 days later after intratracheal BLM instillation respectively with the same volume of NS was given as a vehicle control. The rats were killed on day 7,14 and 28 respectively. Pathological alteration of lung tissue was observed hy HE staining and Masson staining. Hydroxyproline（HYP）content in lung tissue was used to determine the severity of pulmonary fibrosis. The expression of CTGF in lung tissue was exanfined by immunohistochem- istry staining and photodeusitometry. Results Histopathological changes of pulmonary fibrosis emerged gradually after the instillation of BLM. The expression level of CTGF was increased in lungs of rats after intratracheal instillation of BLM, compared with the control. The administration of simvastatin immediately or 7 days after intratracheal instillation of BLM, attenuated the histopathological changes of bleomycin- induced puhnonary fibrosis and prevented the increased expression of CTGF in lung tissue on day 28. Conclusion The adntinistration of simvastatin, immediately or 7 days after intratracheal BLM instillation, prevented the up-regulation of CTGF in fibrotic lungs of rats, which ntight be one of the mechanisms of the anti-fihrosis of simvastatin in lungs.

Objective To study immunoregulatory activity of polysaccharide of mudan cortex (PSM) on immunodepressive mice. Method The immunodepressive mice model was established with cyclophosphamide treated and tumor-bearing. PSM was orally administered to mice for 10 d. MTT method was used to observe the prolifernation of lymphocytes. The function of macrophage in abdominal activity was measured. Sectrophotometric determination was adopted to evaluate the ability of plaque forming cell. Result PSM could enhance the function of macrophage, increase the content of plaque forming cell, and promote the prelifernation of lymphocytes. Conclusion PSM could enhance immunofunction of immunodepressive mice.

Obstructive sleep apnea-hypopnea syndrome(OSAHS) is a common sleep-related breathing disorder,which has a series of impact on the cardiovascular system.The dctection of some biochemical indicators plays an important role in predicting this kind of cardiovascular damage.The role of inflammatory predicting factors such as TNF-?,IL-6,CRP,IL-10,MMPs and ICAM-1 is reviewed in this paper.

Objective To describe the clinical characteristics of a patient with Gitelman syndrome,and to identify the associated SLC12A3 gene mutations.Methods A suspected case of teenager-onset Gitelman syndrome was observed in our hospital.It was further confirmed by clinical manifestations and auxiliary examination.In addition,direct sequencing for the exons of SLC12A3 gene and CLCNKB gene region was conducted to identify the probable disease-associated mutations.Results The case showed characteristics of hypokalemia,hypomagnesemia,and low level of urinary calcium and onset by age of 18.By excluding the possibilities of long-term use of thiazide diuretics,laxatives,chronic vomiting and diarrhea,he was finally diagnosed as a case of Gitelman syndrome.Furthermore,by Sanger direct sequencing,2 coding variations were identified in SLC12A3 gene region,including T304M and L488P.L488P was a new heterozygous mutation.Conclusion Detection of SLC12A3 gene mutation could facilitate the diagnosis of Gitelman syndrome and improve prognosis.

Objective To analyze the quality of life and its influence factors in patients with peptic ulcer.Methods The SF-36 was used to survery 120 patients with peptic ulcer.The QOL scores at different levels of some factors including gender,age,na-tionality,occupation,marriage,medical forms,economic,cultural level,treatment method and clinical type were compared by meth-ods of two sample t-test and analysis of variance.Results Peptic ulcer patients′scores in the domain of RE,PF,RP,BP,GH,VT, SF,RE,PCS and MCS are lower than that of the normal,exception of the domain of MH(P <0.05).The differences were statisti-cally significant.Six factors can be influenced some domain or total score of the scale(P <0.05)and the differences were statistical-ly significant.Conclusion Find out the influencing factors on peptic ulcer patients′quality of life can be provided the basis for clini-cal treatments.

Objective To compare the effects of vitrification with slow-freezing on the developmental ability of day 3 cleavage stage embryos.Methods Patients who had no less than 4 high quality embryos were included in this study.These embryos were cryopreserved using the methods of vitrification or slow-freezing.In the eryopreserved embryo transfer cycles,the embryos which were cryopreserved using one of the methods were chosen randomly.The developmental ability of embryos was compared between these two groups.Results A total of 80 patients were included in this study with 160 embryos.In the group of slow-freezing,73(91%)embryos were survived and achieved 15(38%)clinical pregnancies.Among these,3 were twins and the implantation rate was 25%(18/73).In the group of vitrification,71(89%)embryos were survived and achieved 19(48%)clinical pregnancies.Among these, 9 were twins and the implantation rate was 39%(28/71),which was significantly higher than the slow- freezing group(P

OBJECTIVETo optimize the preparation of genistein chitosan microspheres with central composite design (CCD).

METHODThe chitosan microspheres were prepared by the O/W/O multiple emulsion method. Second-order polynomial and linear equations were fitted to the data, and the resulting equations were used to produce response surface graphs and the best experiment conditions.

RESULTThe theoretical drug content was 13%-15%, the concentration of organic phase was 30%-40% and the concentration of oil phase was 68%-72%.

CONCLUSIONThe best experiment conditions can be obtained by central composite design and response surface methodology. The observed values agree well with model predicted values.
