Pituitary adenylate cyclase-activating polypeptide (PA CAP) which belongs to the secretin/glucagon/VIP family has been originally isola ted from the sheep hypothalamus on the basis of its ability to stimulate cAMP fo rmation in culture rat anterior pituitary cells. Post-translational processing of the PACAP precursor generates two biologically active molecular forms, PACAP -38 and PACAP-27. The primary structure of PACAP has been remarkably conserved during evolution. The sequence of PACAP-27 exhibits substantial similarities w ith those of vasoactive intestinal polypeptide (VIP), glucagon and secretin. The gene encoding the PACAP precursor is widely expressed in brain and various peri pheral organs, notably in endocrine glands, gastro-intestinal，uro-genital tra cts and respiratory system. In vivo and in vitro studies have shown that PACAP exhibits multiple activities especially a trophic activity during ontogen esis, notably in the adrenal medulla and the central nervous system. The biologi cal effects of PACAP are mediated through three distinct receptor subtypes which exhibit differential affinities for PACAP and VIP. The PAC1 receptor, which sho ws high selectivity for PACAP, is coupled to several transduction systems. In co ntrast, VPAC1 and VPAC2, which bind with the same affinity for PACAP and VIP, ar e mainly coupled to the adenylyl cyclase pathway. In conclusion, PACAP is neurop eptide, and it functions as a hypothalamic hormone, neurohormone, neuromodulator , vasodilator, neurotransmitter or trophic factor in the brain and the various o rgans.

Thirty two rabbits were divided into 4 groups: (1) Normal diet control group, ( 2 ) Hyperlipid diet control group, ( 3 ) Hyperlipid diet group injected with 30 mg/kg GSL, ( 4 ) Hyperlipid diet group injected with 60 mg/kg GSL, The whole expeiment took about 42 days. On 24d all hyperlipid diet were removed, and only normal diet given. At the end of this experiment all rabbits were killed by bleeding and the results showed that GSL could decrease the serum lipids GSL could increase the HDL - C in the rabbits injected with 60 mg/kg GSL. GSL could protect the walls of aortas from the damage of hyperlipid serum. The contents of lipid and MDA in the Walls of aortas were decreased. GSL had the effects of protection on the heart and liver by decreasing of Total Cholesterol and MDA. So we conclude that GSL has the effects of lipid regulation and lipid antipeoxidation on the chronic hy-perjipidemic rabits.

Objective:To investigate the curative effect and prognosis of schizophrenia patients treated with paliperidone extended -release tablets.Methods:Totally 72 cases of patients with schizophrenia were divided into the observation group (n=35) and the control group ( n=37 ) according to the order of admission .The obsevation group was treated with paliperidone extended-release tab-lets, while the controll group was treated with risperidone tablets , and both groups were treated for 8 weeks.The positive and negative syndrome scale(PANSS) was used to assess the effect of the two groups , the social function defect scale (SDSS) and prognosis of the two groups were compared.Results: After the 2-week treatment, the PANSS score, positive symptom score, negative symptom score and general symptom score were all decreased in the two groups when compared with those before the treatment (P<0.05),and the scores in the observation group were lower than those in the controll group (P<0.05).After the treatment, the SDSS was significantly reduced in the two groups when compared with that before the treatment (P<0.05), and the reduction in the observation group was more notable than that in the control group (P<0.05).The total effective rate of the observation group was 94.3%, which was higher than that (67.6%) of the control group (P<0.05).The incidence of adverse reactions, such as anxiety and akathisia, and the total adverse drug reactions in the observation group were both lower than those in the control group (P<0.05).Conclusion:Paliperidone extended-release tablets can effectively relieve suffering from schizophrenia with quick effect , few adverse reactions , high safety and good effect , which is worthy of promotion in clinical use .

The difference between the arterial and the end-tidal carbon dioxide tension [P(a-E1)CO2] was observed before and after cardiopulmonary bypass(CPB)was performed in 34 patients,who were divided into 3 groups according to the duration of CPB.It was found that there was an increase of P(a-E1)CO2 after CPB in all the patients and the increase was more significant in Group C(CPB duration of 158 to 186 minutes)than in Group A(CPB duration of 82 to 106 minutes)(P

Objective To evaluate the diagnostic value of serum albumin (Alb),total protein (TP),body mass index (BMI),Mini Nutritional Assessment (MNA) and hand strength in the nutritional status in maintenance hemodialysis (MHD) patients.Methods A total of 126 MHD patients were included in this study who had been on MHD for at least 3 months.Depending on the levels of Alb,patients were divided into two groups:normal nutrition group (group A) and malnutrition group (group B).TP,BMI,MNA and hand strength were also detected at the same time.Independent samples t test,Spearman correlation analysis,ROC curve were used to analyze their difference between the two groups and evaluate their diagnostic value in nutritional status in MHD patients.Results Age,sex,height,weight and dialysis ages had no statistical significant difference (P ＞ 0.05) between group A and group B,while Alb,TP,BMI,MNA and hand strength had statistical significant difference (P ＜ 0.05) between two groups.After adjusting for age,sex and hemodialysis age,Alb,TP,BMI,MNA and hand strength were positively correlated with each other (P ＜ 0.05).Since the area under the ROC curve of BMI was the smallest,BMI had the lowest diagnostic value in evaluation of the nutritional status in those patients.Conclusions Alb,TP,MNA and hand strength are good indexes in evaluation of the nutritional status in MHD patients but BMI is not.

Objective To investigate effects of continuous positive airway pressure (CPAP)treatment on pulmonary function, frequency of asthmatic attack, and quality of life in patients of moderate to severe obstructive sleep apnea syndrome (OSAS) accompanying with asthma. Methods Twenty-three patients of OSAS accompanying with mild-to-moderate asthma were studied. They were divided into two groups, gastroesophageal reflux ( GER ) group ( n = 9 ) and non-GER group ( n = 14 ), based GER questionnaire score equal to or greater than 12, or less than 12. Pulmonary function tests (PFTs), Epworth sleepy score (ESS), quality of life for obstructive sleep apnea (QOLAp) score, quality of life for asthma (QOLAs) score and polysomnography (PSG) were measured for all the patients before and after four-week CPAP, respectively. Results No significant difference in PFTs was revealed before and after four-week CPAP between the two groups. However, there was significant difference in scores of QOLAp, ESS and QOLAs before and after four-week CPAP treatment, ( 12. 8 ± 2. 8 ) and (4. 6 ± 0. 9), ( 5. 1 ± 0. 7 ) and (6.3 ±0.6), and (4. 1 ±0.5) and (6.3 ±0.5) in GER group, and (13.0 ±2.9) and (4.6 ± 1.1),(4.7±0.5) and (5.6±0.6), and (3.6±0.3) and (5.8 ±0.6) in non-GER group, respectively (P＜0. 01 or 0. 05). Frequencies of asthmatic attack and nocturnal asthmatic attack reduced to ( 1.7 ± 1.1 )episodes per week and (0. 7 ± 0. 3) episodes per week after four-week treatment from (2. 9 ± 2. 0) episodes per week and ( 1.4 ± 0. 8) episodes per week before treatment ( P ＜ 0. 05 ) in GER group, but no significant difference was found before and after treatment in non-GER group. Scores of QOLAs increased more significantly in GER group than that in non-GER group ( P ＜ 0. 05 ). Conclusion CPAP treatment can significantly improve quality of life, rather than pulmonary function, in patients of OSAS accompanying with asthma, especially in those with GER symptoms.

Objective To investigate the effect of 15-deoxyspurgualin (DSG) on graft coronary arteriosclerosis (GCA) and the platelet-derived growth factor-A (PGDF-A) mRNA expression of graft myocardium after heterotopic heart transplantation and the possible mechanism. Methods The rat heterotopic heart transplantation model was developed. Two groups of Lewis rats ( n =7 in each group) underwent heterotopic heart transplantationin from Wistar-King donors and were treated with either DSG (5 mg/kg daily, DSG group) or cyclosporine A (10 mg/kg daily, control group). Histological examinations of rejection and coronary arteriosclerosis, as well as Northern blot analysis of graft PDGF-A mRNA expression were made 60 days after transplantation. Results No significant difference in the degree of rejection was found between the two groups. However, the degree of coronary arterial intimal thickening in the DSG group was significantly less than that in the control group ( P

Objective To establish a differently expressed genetic profile in placental tissues of pregnancy induced hypertension(PIH). Method The total RNAs were isolated from the tissues by Trizol and mRNA was purified by Midi Kit. The expression of 17 000 genes in placental tissues of 6 PIH and 5 normoten sive women were evaluated by cDNA array technique. Results Ninety-six differently expressed genes were identified in placental tissue of PIH compared with normal pregnancy cases. Seventy-eight genes were up-regulated and 18 were down-regulated. There were 6 unclassified genes, 8 unknown expressed sequence tag (EST) fragments and 3 cDNA fragments among these differently expressed genes. The differently expressed genes were involved in transcription and translation,cell differentiation,receptor,apoptosis,immune,metabolism and growth. Conclusion The cellular mechanism of PIH involves changes in genes expression in placental tissue. Microarray is a useful method to identify differently expressed genes in tissue.
