Depression is a serious mental disorder characterized by lasting anhedonia and anorexia .The pathophysiology of depression is complicated , which is related to many neuroendocrine disturbances .Increased levels of glucocorticoid hor-mones and hyperactivity of the hypothalamus pituitary adrenal ( HPA) axis are the most consistent and typical pathophysio-logical alternations in patients with major depression , which are possibly caused by altered functions of the receptor of glu-cocorticoid hormones , the glucocorticoid receptor ( GR) .Promoting the expression and function of GR and restoring the im-paired feedback inhibition of the HPA axis seem to be particularly important for the therapeutic efficacy of antidepressants . In this review, the role of GR in the development and resolution of depression is discussed .

The accommodative function before and after laser in situ keratomileusis (LASIK) was observed, and the effect of LASIk on accommodation was investigated. In a prospective clinical trial, 48 myopic patients (96 eyes) subject to bilateral LASIK in Refractive Surgery Center, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology (China) from March 2006 to June 2006 were selected and studied. Refractions, accommodative range, amplitude of accommodative response and high frequency component (HFC) of accommodative microfluctuations were measured with NEDIK-730A before and one week and 30 days after operation. Dominant and non-dominant eyes were determined by hole-in-card method. It was found that all of the operative eyes showed an uncorrected visual acuity of 0.8 or better one week postoperatively, and 1.0 or better 30 days postoperatively. Compared with those preoperatively, accommodative range and HFC had no significant difference at first week and 30th day after operation in both dominant eyes and non-dominant eyes (P>0.05), but there was a significant difference in the amplitude of accommodative response/accommodative stimulus ratio (A/S) after operation (P<0.01), and no significant difference was found in accommodation between one week and 30 days postoperation. No ocular dominance's change was noted. There was no significant difference in accommodative function between dominant eyes and non-dominant eyes. It was suggested that LASIK produced no significant effect on accommodation.

Bile acid efflux pump(BSEP)is the major transporter of bile salts secreted by liver cells into the bile,the variation and inhibition of which are connected with cholestasis and drug-induced liver injury.A deep understanding of the physiological and pathological function of BSEP IS achieved by analysis and summary of diseases.The paper briefly illustrates the structure, expression,regulation,substrates,inhibitors and diseases of BSEP,in order to provide further theoretical and experimental basis for the clinical treatment.

BACKGROUND:Source of bone for autografting,allografting and xenografting is insufficient.Moreover,immunoreaction,infection and re-fracture occur sometimes.As artificial bone substitute.calcium sulfate and calcium phosphate ate widely used in clinic.OBJECTIVE:To compare the curative effect between calcium sulfate(Stirnulan pellets)and calcium phosphate(Bio-Lu bioceramics)as bone substitutions in traumatic fractures.DESIGN.TIME AND SETTING:Randomized controlled observation was performed at the Department of Orthopedics,Beijing Xiyuan Hospital.China Academy of Chinese Medical Science between October 2004 and October 2007.PARTICIPANTS:Fifry patients with bone trauma-induced bone defect who needed bone grafting were selected and randomly divided into two groups:calcium sulfate(n=24)and calcium phosphate(n=26).METHODS:Besides internal fixation(steel-wire,plate)and external fixation(plaster,external frisket),all Cases were filled with bone substitutes.The grafted bone mass was on basis of standards of grafting:generally 3-5mL for Barton fracture and calcaneus fracture.the maximum 10 mL.MAIN OUTCOME MEASURES:Bone substitute usage,resorption time.fracture status and bone callus.RESULTS:All fractures that were filled with bone substitutes were healed well.No abnormal reaction occurred in calcium sulfate group.Two cases with calcium phosphate exhibited effusion in local soft tissue and healed by changing dressing.During the follow-up of 6 months(range 4-12 months),the bone substitutes were absorbed completely.The absorptivity of Stimulan pellets was 80%within 2 mortths and 100%within 3 months.faster than Bio.iu bioceramics(70%within 4-6months:90%within 7-12 mortths).CONCLUSION:The advantages of calcium sulfate and phosphate as bone substitutes are safety.convenience,and few side effects with good filling effect and well fractures healing.Moreover,the calcium sulfate powder(Stimulan)exhibits stronger supporting for bone defect area after soliditication,and faster degradation than calcium phosphate

BACKGROUND: Calcium pyruvate has great effect on reducing bodymass, and chitosan can regulate immunity system, promote bone growth, decrease blood sugar and adjust blood lipid. Calcium pyruvate and chi tosan capsule (CCC) was made by calcium pyruvate and chitosan combined with Chinese medicine, which can be used both as food and medicine. However, its effect still needs further observation. OBJECTIVE: To investigate the weight-reducing effect of CCC on obesity rats, and explore its mechanism.DESIGN: A randomized controlled trial.SETTING: Teaching and Research Section of Preventive Medicine, Department of Public Health, Xi'an Medical College, and Department of Public Health, Medical School of Xi' an Jiaotong University.MATERIALS: The experiment was conducted in the Department of Public Health, Medical School of Xi'an Jiaotong University from April to July 2001. Totally 60 healthy male weaning SD rats with body mass of 50-80 g,were provided by the Animal Center of Xi'an Jiaotong University. CCC,mainly composed of calcium pyruvate and chitosan, mixed with Chinese medicine extract after prepared with distilled water, was made by the author.METHODS: ①Grouping and modeling: The 60 rats were randomly divided into 5 groups: blank control group, model control group, high, middle and low dose CCC supplement groups, respectively with 12 rats in each group. The rats in the blank control group were fed w ith basal diet; the other groups were fed with high fat and nutrition diet to establish rat models of nutritional obesity. ②Administration: The rats in the blank and model control groups were given suspension mixed with starch matrix in capsule and distilled water at same dose. The rats in the high, middle and low dose CCC groups were intragastrically infused with 3, 1.5 and 0.75 g/kg CCC, once aily for 30 days. ③Detection: Body mass, body length and wet weight of fat tissue were measured before and after administration to calculate the obese index and ratio of fat weight/body mass. The adipocyte number and adipocyte size were observed by 400-fold microscope and ocular micrometer, respectively. The detection of serum triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and serum leptin levels were performed according to the leptin radioimmunity analyzer kit.MAIN OUTCOME MEASURES: ①Body mass, body length and obesity index before and after administration. ②Wet weight of fat, fat/body mass,adipocyte number and size. ③TG, TC, HDL-C and serum leptin.RESULTS: All the 60 rats were involved in the result analysis. Before administration, the body mass of the blank control group was obviously lower than other 4 groups (P ＜ 0.01), and there was no significant difference among the 4 groups (P ＞ 0.05). After administration, the mean body mass,obesity index, wet weight of fat tissue, ratio of fat/body mass and leptin level of the high, middle and low CCC groups were lower than the model group (P ＜ 0.05 or 0.01), and the adipocyte size were significantly smaller than those in the model group (P ＜ 0.05 or 0.01), but the adipocyte number was more than the model group (P ＜ 0.05 or 0.01). Meanwhile, level of TG and TC of the high and middle dose CCC groups were lower than the model group (P ＜ 0.05 or 0.01), there was no significant difference in the body length and HDL-C of each group.CONCLUSION: ①CCC shows evident weight-reducing effect on rats with nutritional obesity, which is not related to the ability of CCC to enhance the serum leptin level. ②CCC can also lower the blood lipid level.
