Objective: The effects of two fat substitutes, sucrose polyester(SPE) and triglyceride of short fatty acids(TRIS)on lipid metabolism in rats were studied. Methods: Diets containing either SPE or TRIS were fed to rats for 30d. Male Wistar rats were allowed free access to one of three diets: a control diet containing 20% corn oil, SPE group diet containing 10% SPE and 10% corn oil, TRIS group diet containing 20% TRIS. Plasma glucose, TG, TC, HDL C, LDL C, ApoA I, ApoB were analysed. Results: Dietary fat substitutes lowered total energy consumption and body weight 8.1%?4.1%and 12.3% ?16.0% respectively. Two fat substitutes lowered plasma glucose, TG, TC, LDL C, VLDL C, ApoB level and increased HDL C and ApoA I level. TRIS could decrease TC/HDL C, LDL C/HDL C, ApoB/ApoA I more significantly than SPE. Conclusion: TRIS and SPE have the potential benefits on lipid metabolism and energy intake control in rats, TRIS is more efficient than SPE.

Objective To investigate the association between 5-hydroxytryptamine 2A receptor (HTR2A)gene T102C locus polymorphism and schizophrenia,and to provide basis for evidence-based medicine for the genetic background of schizophrenia.Methods PubMed,EMbase,CNKI,WanFang and Vip information databases were used to search full text of all the relevant studies about the association between HTR2A gene T102C locus polymorphism and schizophrenia,which were published during 2003 to 2012.Based on reviewing full text,the data were selected, evaluated and accessed. RevMan 5.1 and Stata 1 2.0 were used to perform the statistical analysis of those studies that were in accordance with the inclusive criteria. According to the different ethnicities, the obj ects were divided into two subgroups as European and Asian to analyze respectively. Also, depending on different inheritances, the obj ects were divided into five patterns including C/T allele, CC/TT, CC/CT+TT, CC+CT/TT and CC+ TT/CT genotypes to analyze respectively, including heterogeneity inspection, effect consoliating and publication bias assessment. Results A total of 11 studies were available for this analysis, including 2 443 schizophrenia patients and 2 469 controls.The Meta-analysis results showed that the allele of all people were OR=1.12,95%CI=0.96-1.31,P>0.05;CC/TT of all people were OR=1.11,95%CI=0.80-1.53,P>0.05;CC/CT+TT of all people were OR=1.13,95%CI=0.99-1.30,P>0.05;CC+CT/TT of all people were OR=1.18, 95%CI=0.93-1.50,P>0.05;CC+TT/CT of all people were OR=0.95, 95%CI=0.84-1.06,P>0.05.Conclusion Current evidence is insufficient to show that HTR2A gene T102C locus polymorphism may be associated with schizophrenia, suggesting that the gene polymorphism has no significantly genetic association with schizophrenia.

Objective: To investigate the expression of peroxisome proliferator actived receptor ? (PPAR ?)and the inducement of apoptosis by PPAR ? ligand in renal cell carcinoma(RCC) derived cell lines.Methods:RT-PCR and Western blot analysis were performed to determined the expression of PPAR ? mRNA and protein in two RCC derived cell lines(786 O and A498) and two normal kidney(NK) derived cell lines(HK 2 and HMCC). Two RCC cell lines were treated with 50 ?mol/L troglitazoned for and evaluated for the effects of antidiabetic thiazolidinediones (TZDs) on the cells apoptosis by fluorescence microscopy and DNA ladder assay.The mutative expressions of Bcl 2 and Bax before and after TZDs treatment were also performed by western blot analysis. Results: The expression of PPAR ? was observed to be stronger in 786 O and A498 cells than in HK 2 and HMCC cells by RT-PCR and Western blot analysis. Treated with 50 ?mol/L troglitazone (for 48 h) it induced typical apoatosis in 786 O and A498 cells. After treatment, a decrease in Bcl 2 expression in RCC cells was observed by Western blot analysis,and the expression of Bax,however,was up regulated.Conclusion: The results reveal that troglitazone has the tumor suppressive effect on RCC cells. High affinity PPAR ? ligands (TZDs) may be the candidates for a novel approach to the treatment of this refractory neoplasm.

Objective: To analyze the epidemiological characteristics of hospitalized children with burn in Ningbo from 2013 to 2018,and to provide evidence for developing intervention strategies. Methods: The pediatric burn cases,discharged from the Ningbo Women & Children's Hospital from 2013 to 2018,were registered using the Ningbo Hospitalized Injury Monitoring Report Card,and their distributions of time,places,groups,involved body parts and prognosis were analyzed. Results: There were 3 862 pediatric burn inpatients included in this study,with 2 977（77.08%）cases aged 1-3 years and 2 532（65.65%）nonlocal cases. About 898（23.25%）cases occurred during 9:00-12:00 a.m. and 1 833（47.46%）cases occurred during 17:00- 21:00 p.m. Burns predominantly occurred at home,with 3 810（98.65%）cases. The top three body regions involved were multiple regions,lower limbs and upper limbs with 1 820（47.13%）,835（21.62%）and 541 cases（14.01%）. The proportions of involving multiple regions declined with age（Psingle<0.05）. The proportion of involving multiple regions in nonlocal children was higher than that of local children（P<0.05）. Conclusion Burn is one of the leading causes of child injury-related hospitalization in Ningbo. Home is the main burn scene. Nonlocal and 1-3 year-old children were especially at high risk of burns.

OBJECTIVEIn order to investigate the potential mechanisms in troglitazone-induced apoptosis in HT29 cells, the effects of PPARγ and POX-induced ROS were explored.

METHODS[3- (4, 5)-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) assay, Annexin V and PI staining using FACS, plasmid transfection, ROS formation detected by DCFH staining, RNA interference, RT-PCR & RT-QPCR, and Western blotting analyses were employed to investigate the apoptotic effect of troglitazone and the potential role of PPARγ pathway and POX-induced ROS formation in HT29 cells.

RESULTSTroglitazone was found to inhibit the growth of HT29 cells by induction of apoptosis. During this process, mitochondria related pathways including ROS formation, POX expression and cytochrome c release increased, which were inhibited by pretreatment with GW9662, a specific antagonist of PPARγ. These results illustrated that POX upregulation and ROS formation in apoptosis induced by troglitazone was modulated in PPARγ-dependent pattern. Furthermore, the inhibition of ROS and apoptosis after POX siRNA used in troglitazone-treated HT29 cells indicated that POX be essential in the ROS formation and PPARγ-dependent apoptosis induced by troglitazone.

CONCLUSIONThe findings from this study showed that troglitazone-induced apoptosis was mediated by POX-induced ROS formation, at least partly, via PPARγ activation.

Objective To compare the cumulative analgesic effects of electroacupuncture at Sanyinjiao (SP6), Xuanzhong (GB39) and non-acupoint in treating primary dysmenorrhea. Method By adopting a multi-centered randomized controlled study method, 501 patients recruited from Dongzhimen Hospital of Beijing University of Chinese Medicine, China-Japan Friendship Hospital, Beijing Hospital of Traditional Chinese Medicine of Capital Medical University, First Teaching Hospital of Tianjin University of Traditional Chinese Medicine, Huguosi Hospital of Chinese Medicine of Beijing University of Chinese Medicine and the Outpatient of Shandong University of Traditional Chinese Medicine were randomized into a Sanyinjiao group, a Xuanzhong group, and a non-acupoint group, 167 subjects in each group. The electroacupuncture intervention was applied when dysmenorrhea flared up and the Visual Analogue Scale (VAS) ≥40 mm, with frequency at 2/100 Hz and intensity during patient’s endurance, 30 min each time, once a day, and for successive 3 d. Before the first treatment, 30 min after the first treatment, and respectively prior to the second and third treatment, VAS was used to measure the pain intensity. Meanwhile, the Retrospective Symptom Scale (RSS-COX 2) was investigated before the first treatment, right after the removal of needles for the first treatment, before the second and third treatment. Result The decrease of VAS in Sanyinjiao group was more significant than that in Xuanzhong group and non-acupoint group (MD=﹣2.92 mm, P=0.028; MD=﹣3.47 mm, P=0.009), while there was no significant difference between Xuanzhong group and non-acupoint group (MD=﹣0.56 mm, P=0.674); there were no significant differences in comparing the RSS-COX2 total score among the three groups (P=0.086). Conclusion Sanyinjiao (SP6) can produce a more significant cumulative analgesic effect for primary dysmenorrhea patient than Xuanzhong and non-acupoint, and the effects of Xuanzhong and non-acupoit are equivalent.
