Objective: To study the subjective of well-being and influential factors of medical chronic inpatients. Methods: 322 chronic pulmonary heart disease, diabetes, hypertension and coronary atherosclerotic heart disease' inpatients were tested by Index of Well-Being, SAS, T-AI and SDS. Results: ①The sense of Well-Being of these patients was obviously higher than the healthy people, and the sense of well- being of hypertension and coronary atherosclerotic heart disease' inpatients was better than other groups. ② By multi-variable stepwise regression analysis, the T-AI was the most powerful negative influential factor on the Subjective Well-being of the chronic patients. Furthermore, it was also closely related to the patients' SDS, the kind of disease and SAS. Conclusions: Since the patients have lower sense of Well-being, and it can be improved by reducing their negative emotions such as anxiety and depression, therefore, the nurses should pay attention to the psychological support of the patients so that their metal status can be improved and also the quality of nursing can be enhanced.

BACKGROUND: The study on the candidate gene of schizophrenia was one of the major ways of exploring its etiology. One of important candidate genes associated with schizophrenia is the brain-derived neurotrophic factor gene(BDNF)OBJECTIVE: To explore the association between schizophrenia and C270T polymorphism of BDNF gene.DESIGN: Case-control and comparative observation SETTING: Institute of Mental Health of Central South University PARTICIPANTS: Totally 194 patients with schizophrenia, including 95 males and 99 females aged from 15 to 59 years, hospitalized in man and women wards in the Institute of Mental Health, Xiangya Second Hospital of Central South University from March to October 2003 were set as patients group. Controls were selected among the healthy volunteers of Xiangya Medical College was included in terms of age and gender comparable with patients group. Altogether 187 cases of controls, of whom 88 males and 99 females were studied. Their age ranged from 18 to 42 years old with the average of (26±7) years old.Those with psychosies and severe somatopathy were excluded. The patients and their family member have no history of psychosis .All the subjects were of Hunan Han nationality. Either the patient or his or her family members signed the written consent form. Individuals in the control group also signed the written consent form.positive symptom scale (PANSS-P) (7 items), negative symptom scale (PANSS-N) (7 items) and General Symptom Scale (PANSS-G) (16 items),altogether 30 items, as well as 3 additional items to evaluate the attack fatalness were used to evaluate whether the psychic symptom existed or not and the degree of severity of each symptom(7-item scoring: 1 was without,7 was very severe) . The patients were evaluated on the day of hospitalizing was used to compare the frequency among groups.polymorphism of BDNF gene between patients group and healthy control RESULTS: Totally 194 patients with schizophrenia and 187 healthy genotype (26.8%) in patients was much higher than that of the healthy controls (5.9%) (x2=32.71, df=1, P ＜ 0.01).The distribution frequency of T allele in patients' group (14.4%) was much higher than that in the scores, PANSS-P, PANSS-N and PANSS-G scores in patients with the genotype of C/T were 59-121 ;9-42( average 20.08±6.16);8-41 (average 19.02±9.13);22-68 (average 36±8.02)respectively. And the total PANSS scores, PANSS-P, PANSS-N and PANSS-G scores in patients with the genotype of C/C were 58-121 ;7-39, (average 19.2±5.88);8-40scores, (average19.02 ±8.98); 22 -68 (average36.4 ±8.32)respectively.There were no significant differences in positive and negative symptom scale (PANSS)items as well as PANSS-G between the patients with C/C and C/T genotype(P ＞ 0.05).CONCLUSION: BDNF gene C270T polymorphism was associated with the susceptibility of schizophrenia. The distribution frequency of T/C genotype and T allele in schizophreniac was significantly higher than those of the normal healthy controls. And no significant difference was obtained between patients with the genotype of T/C or C/C in terms of negative,positive symptoms and psychosocial function as well.

This study was aimed to investigate the preventing efficacy of the combined using of Er-Shi-Wu-Wei Shan-Hu (ESWWSH) pill, Ru-Yi Zhen-Bao (RYZB) pill, Er-Shi-Wei Chen-Xiang (ESWCX) pill on the focal cere-bral ischemia injury in rats. A total of 80 Sprague-Dawley (SD) rats were randomly divided into four groups. In the sham operation group and the MCAO model group, normal saline was given orally every day (1 mL/100 g). In the positive control group, nimodipine was given orally every day (1.89 mg/100 g). In the drug combination group, ESWWSH pill (7 mg/100 g), RYZB pill (31.5 mg/100 g), ESWCX pill (49 mg/100 g), were separately given in the morning, noon and evening every day. Improved MCAO was used in the model establishment after 7-day intragastri-cal administration. After 24 h brain infarction, TTC method was used in the determination of the cerebral infarct size. Drying and weighing method was used in the calculation of brain water content. Determinations were made on con-tent of NO in ischemic brain issues (nitrate reductase method); activities of SOD in serum (xanthine oxidase method);content of MDA in serum (TBA method); and activities of LDH in serum (pyruvate method). The results showed that compared with the MCAO model group, the combined using of three Tibetan classical prescriptions can obviously re-duce the cerebral infarct size, brain water content and the NO content in brain issues, increase the activity of SOD, reduce the content of MDA, and reduce the activity of LDH in serum. It was concluded that the research preliminari-ly showed that the combined using of ESWWSH pill, RYZB pill and ESWCX pill can protect the ischemic brain tis-sues, such as reducing the cerebral infarct size, alleviating brain edema, and inhibiting oxidative stress reactions.

AIMTo investigate whether DADS induce MGC803 cell apop tosis and cell cycle arrest. METHODSMGC803 cell growth inhibitio n was measured by MTT assay. Flow cytometry and acridine orange fluorescent stai ning method were used to determine the induction of apoptosis and the change of cell cycle. RESULTSMTT assay showed that adding 20,30,40 mg?L -1 DADS for 72 h suppressed MGC803 growth by 25 7%,58 6%,69 0% respective ly. Partial cells presented the characteristic morphological changes of apoptosi s under the fluorescent microscope. The apoptosis rate ncreased in time-depende nt manner. Flow cytometry analysis revealed that treating MGC803 cell with DADS significantly increased in the percentage of cells in the G 2/M phase. The proportion of cells in the G 2/M phase after treatment with 30 mg?L -1 DADS for 24 hours was comparable (46 0%), and more than four times that occu rring in untreated cells (9 9%). Furthermore, flow cytometry analysis also demonstrated that DADS induced apoptosis of MGC803 cell in time-dependent manner. T he pencentage of apoptotic cell was 3 53% after 0 h of 30 mg?L -1 DADS tr eatment. This pencentage of apoptotic cell rose steadily over time reaching 9 8 % after 24 h and 39 5% after 48 h. CONCLUSIONDADS could induce apoptosis of MGC803 cells and block the cell cycle at G 2/M phase.

An ultra-high performance liquid chromatography-mass spectrometry ( UPLC-MS/MS) method was developed for the determination of 8 kinds of cephalosporins, cefoperazone, cefquinome, cefalonium, cefazolin, cefapirin, Ceftiofur, cefpirome and cefalexin, in edible parts of aquatic products. The samples were extracted with acetonitrile-water and cleaned up by multi-walled carbon nanotubes ( MwCNTs) SPE cartridge. All the target compounds were separated on an Acquity Xselect CSH C18 column with gradient elution by using acetonitrile and 0. 1% formic acid aqueous as eluent, and detected by UPLC-MS/MS under ESI+ ionization and MRM mode. Under optimized conditions, this method had a good linearity (R2≥0. 995) and the limits of quantification were in the range of 2-10 μg/kg ( S/N=10 ) . The recoveries of the method for the target compounds spiked at three different levels were 67. 3%-94. 2% with the relative standard deviations (RSDs) of 3. 3%-14%. The method had the characteristics of low cost, high accuracy and good precision, and could meet the requirements of cephalosporins determination.
