With the improvement of people's living standard,the occurrence of children obesity is also increasing.Children obesity not only affects children' s growth,but also is closely related to the occurrence of many diseases in adults.Therefore,prevention and treatment of child overweight and obesity are very important for improving people's health.This paper summarizes several childhood obesity intervention in recent years.

Objective To observe the effects of 1,3-dipropyl-8-cyclopentylxanthine(DPCPX),an adenosine A1 receptor antagonist,on brain neurons damage induced by hypoxia and reoxygenation(H/R),and to elucidate the relevant mechanisms.Methods An in vitro cultured rat cerebral cortical neuronal H/R damage model was established;the effects of DPCPX were detected at final concentrations of 0(control),25,50,100nmol/L on the lactate dehydrogenase(LDH) release from normoxic neurons and H/R neurons which were treated with hypoxia for 8,12,24 hours followed by reoxygenation for 24 hours;the changes of malondialdehyde(MDA) content,activities of xanthine oxidase(XO) and Ca2+-ATPase in H/R neurons which were treated with hypoxia for 12 hours and reoxygenation for 24 hours brought by administration of DPCPX at the concentration of 100nmol/L were also determined by use of specific reagents.Results With addition of 100nmol/L DPCPX,the LDH release from H/R neurons which were treated with hypoxia for 12 hours and reoxygenation for 24 hours was significantly increased compared with that in control group(P

OBJECTIVE:To observe clinical efficacy and safety of Ginkgo biloba extract combined with olmesartan me-doxomil in the treatment of essential hypertension,and to discuss its effect on the expression of serum protein. METHODS:98 pa-tients with essential hypertension were selected and randomly divided into observation group A and observation group B,with 49 cases in each group;40 healthy volunteers were included in control group. Observation group A was given Olmesartan medoxomil tablet 20-40 mg,po,qd;observation group B was given Olmesartan medoxomil tablet 20-40 mg,po,qd+ Extract of G. biloba leaves tablet 40-80 mg,po,bid. Treatment course lasted for 4 weeks. Blood pressure(SBP and DBP),TCM symptom score,the repeti-tiveness and resolution ratio of 2-DE spectrum,protein differentiation expression point,related information of differentiation expres-sion protein in 3 groups and ADR of observation group were observed. RESULTS:After treatment,SBP,DBP and TCM symptom score of observation group were significantly lower than before;those indexes after 4 weeks of treatment were significantly lower than those after 2 weeks after treatment;the observation group B was significantly lower than the observation group A,with statisti-cal significance(P<0.05). The repetitiveness and resolution ratio of protein differentiation expression point in observation group B were significantly better than in observation group A after treatment. The expression of 15 protein points in observation group down-regulated before treatment,and up-regulated after treatment to different extents;the observation group B was closer to control group,compared to observation group A. The expression of 6 protein points up-regulated,and then down-regulated to different extent after treatment;the observation group B was closer to control group,compared to observation group A. A total of 11 protein points were identified. There was no statistical significance in the incidence of ADR between observation group A and observation group B (P>0.05). CONCLUSIONS:G. biloba extract combined with olmesartan medoxomil greatly influences the expression of serum pro-tein in patients with essential hypertension and shows good antihypertensive and pressure-control effects with good safety.

Extranodal NK/T-cell lymphoma,nasal type (ENKTL) is a aggressive lymphoma which arises from NK cells or T cells and has a poor prognosis.This article mainly reviewed and focused on hematological stem cell transplantation in treating ENKTL.

Extranodal NK/T cell lymphoma,nasal type is a common subtype of non-Hodgkin's lymphomas in China.Many difficulties remain in its diagnosis and treatment.Correct diagnosis can be established according to the typical histology findings and immunology phenotypes with CD33（E）,EBER and/or CD56 positive.Prognostic factors should be assessed in the initiation of diagnosis.Ann Arbor staging classification has still being widely used and PET-CT scan is strongly recommended.Chemotherapy followed by radiotherapy should been considered for early-stage patients and combined chemotherapy is the best choice for advanced stage patients.The regimens containing L-asparaginase should be considered firstly due to the evidences from many clinical trials.Stem cell transplantation is recommended to almost all patients except for IE stage patients without any unfavorable prognostic factor.New regimens should be investigated and assessed in the perspective randomized clinical trials.

Neuroendocrine cells comprise a minor subpopulation of the normal prostatic epithelium. When patients accept the androgen deprivation therapy, it will induce neuroendocrine differentiation of the prostate carcinoma cells. NE cells can provide endocrine/paracrine stimuli for proliferation of the surrounding carcinoma cells and inevitably make prostate cancer become androgen independent and no longer responsive to hormonal manipulation. In this paper, the mechanism of neuroendocrine differentiation and its relationship with androgen independent state were reviewed.

目的观察苁蓉通便汤治疗老年性便秘的临床疗效。方法将 62例老年性便秘患者分为两组。治疗组(32例)内服苁蓉通便汤,对照组(30例)内服麻仁润肠丸。结果治疗组疗效优于对照组(P<0.05)。结论苁蓉通便汤对老年性便秘疗效显著。

The expression of CD107a,NKG2D on the surface of natural killer (NK) cells and serum soluble major histocompatibility complex class Ⅰ chain-related A (sMICA) level in patients with extranodal NK/T cell lymphoma,nasal type (ENKL) were detected.We found that CD107a expression was reduced on the surface of NK cells,suggesting impaired NK cell activity in ENKL patients,which may result from decreased NKG2D expression.

Objective To observe the therapeutic effect of ai-weizhi on anterior ischmic optic neuropathy (AION). Methods In 58 patients (60 eyes) who were diagnosed as with AION, 29 patients (30 eyes) underwent intravenous drip with ai-weizhi (1 200 mg/d) (treatment group), and the other 29 patients (30 eyes) underwent intravenous drip with 1-2 kinds of thrombolytic coagulant or vasodilator (once per day) (control group) with the period of treatment of 15 days. In the control group, ocular local injection, including gluco-corticosteroid and 654-2 behind or beside the eyeball injected once per day or every 2 days for 3-5 times, was perfomed on 20 eyes simultaneously. The changes of visual acuity and ocular fundus of the patients after injection were recorded, and the visual field was counterchecked in the patients who had underwent the examination before the treatment. Results The visual acuity was better in treatment group than which in control group with a significant difference (t=2.74, ?0.05). At the 5th、 10th and 15th day after treatment, the visual acuity was better in treatment group than which in control group with a significant difference(t=2.01, P

Objective To study previous cesarean section effects on re-eesarean section, and to seek better operation way of cesarean section. Methods The conditions of entrance into abdominal cavity and adhesion of 452 cases of abdominal cavity were retrospectively analyzed. The information about initial operation was investigated, dis-covering 104 cases underwent new type,and 348 cases underwent improved cesarean section. Results Time of en-trance into abdominal cavity once more by new type of cesarean section were (9.25±2.27) min and the incidence of adhesion in abdominal cavity was 18.27%,while time of entrance into abdominal cavity once more by improved cesarean section were (7.23±2.21) min and the incidence of adhesion indominal cavity was 9.87% (u=8.016, P<0.05; χ25.57,P<0.05). Conclusion New type of improved cesarean section has little effect on re-cesarean section, worthing more clinical practice.
