Objective To determine associations between weight gain induced by antipsychotic and the polymorphisms of HTR2C gene -759C/T and -697G/C,histamine-1 receptor gene,leptine gene -2548G/A,and adiponectin gene +276G/T and +45T/G.Methods In the casematched study,85 patients who gained more than 7％ of their pre-drug body weight served as the study group and another 85 patients who gained less than 7％ of their pre-drug body weight served as the control group.The ligation diction reaction technique was used to analyze the frequencies of the -759C/T and -697G/C polymorphism of the HTR2C gene,-2548A/G polymorphism of leptin gene,+ 276G/T and + 45T/G polymorphism of adiponectin gene and glu349asp polymorphism of H1 receptor gene.Results The presence of the -759C allele,-697G allele,-2548A allele and + 276G allele was significantly higher in the study group than that in the control group (P ＜ 0.05 ).Conclusion The -759C/T and -697G/C polymorphisms of the promoter region of 5HT2C receptor gene,-2548A/G polymorphisms of leptin gene and + 276G/T polymorphisms of adiponectin gene may be associated with the antipsychotic induced weight gain.The glu349asp polymorphisms of histamine-1 receptor gene is not associated with antipsychotic induced weight gain.

The liver is an important organ of the body,with an extraordinary capacity for responding to physical or chemical injuries by regenerating. The mechanisms behind liver regeneration are very complicated as hundreds of substances are involved.However,most of them are not liver-specific,such as HGF,EGF etc. We recently isolated a pure protein with hepatic stimulatory activity from the extract of a weanling calf liver and named its hepatopoietin Cn (HPPCn).This paper,with reference to our own work, mainly reviews the development and bioactivity about hepatic stimulator substance(HSS),augmenter of liver regeneration(ALR),hepassocin(HPS) and HPPCn,which are liver-specific biologically active peptides.

Objective To study the mechanisms of Curcumin-induced apoptosis on human gastric cancer cell line SGC-7901.Methods SC,C-7901 cells were treated with various concentrations of Curcumin and the growth inhibition rates of it were accessed by MTT method.Apoptosis of gastric cancer cells were in- spected by flow cytometry.The expression of Fas and survivin in gastric cancer cells were evaluated by west- ern blot.Results Curcumin could effectively inhibit the growth of gastric cancer cells in dose-dependent and time-dependent manners,the sub-peak appeared and the apoptotic rate was increased.The expressions of Fas was higher in Western blot,meanwhile,the expressions of survivin was decreased.Conclusion Curcumin could significantly inhibit the growth and induce apoptosis of gastric cancer cells(SGC-7901),Curcumin could probably through up-regulating Fas and down-regulating surviving to induce apoptosis.

Objective: To study the effect of ?-3 polyunsaturated fatty(?-3 PUFA) on the serum lipid of ovariectomized rats.Methods: 60 virgin female Sprague-Dawley rats,3 months of age,were randomized by the stratified weight method into 6 groups: Sham group:deionized water 2 mL/d,OVX group:eionized water 2 mL/d,E2 group: OVX+17?-ethinylestradiol 0.1 mg/(kg?d),A group: OVX+?-3 PUFA 75 mg/(kg?d),B group: OVX+?-3 PUFA 150 mg/(kg?d) and C group: OVX+?-3 PUFA 300 mg/(kg?d).Each group had 10 rats.Experiment period was 90 days.Body weight were measured every week.Serum were collected to measure Cholesterol(TC),Triglyceride(TG),High-density lipoprotein-cholesterol(HDL-C),and Low-density lipoprotein-cholesterol(LDL-C).Results: There were significant difference between groups in the serum lipid.In the OVX group,TC and LDL-C increased.In the E2 group,TC increased compared with that in the Sham group,and HDL-C,LDL-C and HDL-C/TC decreased significantly compared with that in the OVX group.In the A,B and C groups HDL-C/TC increased significantly compared with those in the E2 group.Conclusion: The ovariectomized rats have lipid metabolism disorderd.The ?-3 PUFA and estrogen replacement therapy plays a role in the lipid metabolism.The ?-3 PUFA has the best efficiency in reducing the level of serum lipid.

Objective To assess the early prognosis of 117 patients after carduopulmonary resuscitation (CPR) in ICU by using the markers of inflammation,Glasgow Coma Scale (GCS) and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores.Methods A total of 117 CPR patients admitted between 2010 January to 2012 December were enrolled for study.Within 24 h after admission,inflammatory markers,blood routine items,hepatorenal function,electrolytes of blood were measured.The GCS and APACHE Ⅱ scores were recorded.Arterial blood gas analyses were performed at 0,12,and 24 h after hospitalization,and the 12-h and 24-h lactate clearance rates were calculated.Seven days after treatment,according to the outcomes,the patients were divided into survival group and death group,and the clinical data of two groups were analyzed.Results (1) Of them,73 patients died and 44 survived.Factor analysis showed that age,time elapsed from resuscitation to ICU admission,D-dimer,arterial oxygenation index (FiO2),arterial blood pH,arterial blood lactate concentration upon ICU admission,GCS score and APACHE Ⅱ score were significantly different between the two groups (P ＜ 0.05or P ＜ 0.01); (2) Two classification logistic regression analysis showed that D-Dimer,GCS score and APACHE Ⅱ score significantly correlated with the mortality risk of the patients in the wake of CPR with relative odds ratios of 1.000,2.091,and 0.531,respectively (P ＜ 0.05 or P ＜ 0.01) ; (3) Receiver operating characteristic curve analysis indicated that the area under the curve of GCS (0.821) and APACHE Ⅱ (0.869) had higher predictive value than D-dimer (0.655).The highest accuracy (84.6％) in predicting patient survival was achieved when the GCS score was 6.5.Meanwhile,the highest accuracy (82.1％) in predicting patient death was achieved when the APACHE Ⅱ score was 17.5.Conclusions Both GCS score and APACHE Ⅱ score has obvious correlation with the prognosis of the critically ill patients after CPR and could be used to predict prognosis at early stage.

Objective To explore the efficacy and security of helical tomotherapy (radical radiotherapy) combined with targeted therapy for stage Ⅳ non-small cell lung cancer (NSCLC).Methods The data of 19 patients with stage Ⅳ NSCLC were retrospectively analyzed.The efficacy and security were observed by SPSS 20.0 statistical software.Results Among 19 patients, there were 6 cases complete remission (CR), 8 cases partial remission (PR), 4 cases stable disease (SD), 2 cases progressive disease (PD).The response (CR+PR) rate was 73.7 ％ (14/19).The 1-and 2-year local control rates were 73.7 ％, 47.4 ％,respectively.The 1-year progression-free survival rate was 31.6 ％.The median survival time was 13 months, and the 1-and 2-year overall survival rates were 52.6 ％, 26.3 ％, respectively.The median survival time of females, non-smokers or targeted therapy synchronous radiotherapy was longer than that of male, smokers or targeted therapy sequential radiotherapy, respectively (21 months vs 8 months, P =0.014;21 months vs 6 months, P =0.007;18 months vs 6 months, P =0.026).There were no significant differences of age, number of metastatical organs or targeted drug categories between two groups (P ＞ 0.05).All patients could tolerate the adverse reactions without treatment-related death.Conclusion The effect of helical tomotherapy combined with targeted therapy for stage Ⅳ NSCLC is desirable.

Objective To evaluate the efficacy and side effects of whole body γ/-knife in patients with limited pancreatic carcinoma. Methods 111 patients with limited pancreatic carcinoma treated with the Stereotactie Gamma Ray Whole-Body Therapeutic System (Whole Body T-knife) were retrospectively an-alyzed. Patients were supine, fixed with a stereotactic body frame and vacuum bag, and then simulated by low-speed computed tomography. GTV, CTV and PTV were defined on the contrast-enhanced CT scans. It was required that 50% isedose line covered 100% of PTV and 70% isedose line covered more than 80% of GTV. The prescription dose was defined as 50% isodose. All patients were treated 5 fractions per week. The fractionated dose was 3-4 Gy for pancreatic head carcinoma, and 4-5 Gy for pancreatic body/tail carcino-ma. Irradiation of 40-51 Gy and 60-70 Gy were delivered to PTV and GTV margins, respectively. Re-suits The complete response rate, partial response rate and overall response rate of the primary tumors were 29.7%, 42.3% and 72.1%, respectively. The follow-up rate was 95.5%. The number of patients fol-lowed-up at 1-,2- and 3-year was 105,89 and 60. The 1-, 2- and 3-year overall survival rates were 49.3%,24.5% and 18.1%. For patients with stage Ⅰ/Ⅱ disease,the number of patients followed-up at 1-,2-,3-,4-and 5-year was 55,44,29,16 and 11 ;The 1-, 2-, 3-,4- and 5-year overall survival rates were 68%,34%, 30%, 21% and 17%, respectively. For patients with stage Ⅲ disease,the number of patients fol-lowed-up at 1-,2- and 3-year was 50,45 and 31 ;The 1-, 2- and 3-year overall survival rates were 28%,14% and 4%, respectively (χ~2=16.67, P=0.000). The acute side effects including nausea, vomiting and diarrhea were 71.2% of RTOG grade 1 -2 and 3.6% of RTOG grade 3. No treatment delay occurred.Conclusions With fractionated dose of 3-5 Gy,5 fractions per week and 40-51 Gy as total dose to PTV,whole body γ-knife is safe and effective to treat limited pancreatic carcinoma. The local control and overall survival could be improved.
