Identification and determination of hyoscine in Zhichuanling Injection were carried out by TLC. It was suggested that TLC-colorimetry could be sued to determine hyoscine content. The method showed a good separation,high specificity,but lower requirement for apparatus.

Carbon monoxide(CO) has been considered as a fatal gas.Recent researches show that tissues generate carbon monoxide,and carbon monoxide plays a key role in the tissue physiological and pathological processes.The endogenous CO is generated from the decomposition of heme which is catalyzed by heme oxygenase enzyme(HO).Studies show that CO involves in the process of anti-inflammation,anti-apoptosis,regulation of vascular tone,modulation of leukocyte adhesion and platelet aggregation.CO also functions as neurotransmitters.

Objective:To explore the effect of behavioral training of creative art therapy(CAT) on interpersonal communication in teenagers.Methods:Eighty teenagers were randomly divided into study group( n=40) and control group( n=40).The study group was received the behavioral training of CAT (12 times, each activity lasts for 120 min), and the control group did not take part in the behavioral training of CAT.The two groups were measured with self-esteem scale(SES), shyness scale(SS) and social anxiety scale for children(SASC) before and after behavior training.SPSS 17.0 software was used for statistical analysis, and t-test variance analysis and Mann-Whitney U test were used to compare the differences between groups or within groups. Results:Before and after behavioral training, changes in the SES total score (7.00(5.00, 9.75) vs 1.00(0, 2.00)), the SS total score (7.00(6.00, 12.75) vs 2.00(1.00, 3.00)), the SASC total score (5.00(2.00, 8.75) vs 0(0, 1.00)) and two factor scores (3.00(0.25, 5.00) vs 1.00(0, 1.00), 2.00(1.00, 4.00) vs 0(0, 1.00))in the study group were obviously higher than those in the control group( Z=-7.347, -7.338, -5.841, -4.122 and -5.393, all P<0.05).The score differences of the SASC total score ((7.19±3.82) vs (3.21±3.04)) and two factor scores ((4.00±2.23) vs (1.68±2.05), 3.00 (1.00, 5.00) vs 2.00 (0, 2.00)) of girls were significantly higher than those of boys in the study group ( t=-3.611, -3.398, Z=-2.111, P=0.001, 0.002, 0.035). Conclusion:Behavioral training of CAT can improve teenagers' self-esteem, relieve their shyness and social anxiety, as well as promote their interpersonal communication.

Objective To study the effects and the mechanism of exogenous carbon monoxide on apoptosis of rat intestinal cells during endotoxemia. Methods The experimental rats were divided into 6 groups:control group, LPS(lipopolysaccharide: 5 mg/kg) group, CO inhalation(250?10~ -6) group, CO intraperitoneal injection(2 ml/kg) group, LPS(LPS 5 mg/kg) with CO inhalation(250?10~ -6) group and LPS(LPS 5 mg/kg) with CO intraperitoneal injection(2 ml/kg) group. The PaO_2, PaCO_2, SO_2 and COHb were monitored by blood gas analysis. The rat intestine malondialdehyde(MDA) was determined by thiobarbitric acid method and superoxide dismutase(SOD) was determined by hydroxylamine method after the rats were treated for 1, 3 and 6 hours. We also checked the apoptosis ratio of intestinal cells with flow cytometry(FCM). We also monitored the pathological changes with HE staining. Results Low concentration CO(250?10~ -6) inhalation and CO intraperitoneal injection(2 ml/kg) did not cause hypoxia. Comparing to control group and endotoxemia group,the intestineal MDA of the endotoxemic rats decreased after exposure to exogenous CO and the SOD activation increased. The apoptosis ratio of intestinal cells decreased after exposure to exogenous CO. On the apoptosis of endotoxemia rat intestinal cells, the effect of CO intraperitoneal injection was earlier than that of CO inhalation, but the effect of CO inhalation last longer. Conclusion Low concentration CO(250?10~ -6) inhalation and low dose CO(2 ml/kg) intraperitoneal injection were safe to rat. Exposure to exogenous CO could protect rat intestine against endotoxemia by inhibiting the apoptosis of intestinal cells. The effect of intraperitoneal CO injection was earlier than that of CO inhalation, but the effect of CO inhalation could last for longer than intraperitoneal CO injection.

Objective To explore the sleep quality and its influencing factors among the patients with schizophrenia of Hui and Han populations in the rural areas in Ningxia Hui Autonomous Region.MethodsTotally 296 patients with schizophrenia of Hui and Han populations in the rural areas were selected from 2 counties of Wuzhong and Zhongwei in Ningxia Hui Autonomous Region by using cluster random sampling method.Self-made general information questionnaire was used to collect the demographic and clinical characteristics of the patients with schizophrenia.The Pittsburgh Sleep Quality Index(PSQI) was used to evaluate the sleep quality.Brief Psychiatric Rating Scale(BPRS),Hamilton Depression Scale(HAMD) and Hamilton Anxiety Scale(HAMA) were used to measure the psychotic symptoms,depressive symptoms and anxiety symptoms,respectively.ResultsIn the rural areas,the incidence of sleep disorder in the patients with schizophrenia of Hui and Han populations was 84.5%.The influencing factors of sleep disorder in the patients with schizophrenia in the rural areas were age(B=0.055,P=0.012,OR=1.057,95%CI:1.012-1.103),nationality(B=2.250,P<0.01,OR=9.485,95%CI:2.701-33.319),marital status(B=-1.506,P=0.003,OR=0.222,95%CI:0.081-0.605),course of disease(B=-0.003,P=0.089,OR=0.997,95%CI:0.993-1.001),the total score of HAMD(B=0.079,P=0.007,OR=1.083,95%CI:1.021-1.148)and the total score of HAMA(B=0.060,P=0.036,OR=1.061,95%CI:1.004-1.122).ConclusionSleep disorders are common and associated with multiple factors in patients with schizophrenia of Hui and Han populations in Ningxia rural area.In clinical practice,more attention should be paid to the identification and intervention of sleep disorders,so as to improve the sleep quality for the patients with schizophrenia.

Objective To investigate the relationship between the delivery gestational age, birth weight and fidgety movement. Methods 81 infants in fidgety movement phase were divided into preterm group and full-term group according to their delivery gestational age, into <2500 g group and ≥2500 g group according to their birth weight. The number of different kinds of General Movements (GMs) was compared.The correlation between birth weight, delivery of gestational age and GMs was analysed. Results The number of fidgety movement was more in the full-term group than in the preterm group (P=0.001), while the number of absence of fidgety movement was significantly less (P=0.003). The number of fidgety movement was more in the ≥2500 g group than in the <2500 g group (P=0.001), the number of absence of fidget movement was significantly less (P=0.003). The GMs was correlated with birth weight and delivery gestational age. Conclusion Premature and low birth weight are the risk factors for abnormal fidgety movement.

Objective To explore the best range of international normalized ratio for anticoagulation treatment after mitral valve replacement (MVR) and double valve replacement (DVR).Methods We conducted a follow-up study involving 1592 patients who received the warfarin anticoagulant therapy after MVR or DVR in our hospital.Clinical data was collected including the admission information,the dose of warfarin and the INR level,and the occurrence of bleeding and thrombosis were recorded.The patients were divided into 2 (MVR and DVR) groups in terms of the different valve prostheses,and then each group was assigned to four subgroups according to their INR level ( A:INR=1.4-1.7;B:INR=1.7-2.0;C:INR=2.0-2.3;and D:INR=2.3-2.6) to compare the incidence of bleeding and thrombosis among these subgroups.Results The analysis of the incidence of bleeding:In MVR group,the subgroups with different INR levels had significant difference with participants with INR level at D having higher incidence of bleeding than the other 3 groups (Group A:x2=17.991,Group B:x2=13.436,Group C:x2=7.186;P＜0.01 ).We observed significant difference in DVR groups (x2=19.067,P＜0.01 ) with the increased incidence of bleeding of INR level at D compared with the other three groups ( Group A:x2=16.736,Group B:x2=10.486,Group C:x2=7.773;P＜0.01 ).The analysis of the occurrence of thrombosis;The groups of MVR and DVR had no significant differenceson in the incidences of thrombosis in all the levels of INR ( P ＞ 0.05 ).No significant statistical differences were found on the incidence of bleeding and thrombosis at INR level 1.4-2.3 ( P ＞ 0.05 ) Conclusion The present study suggestes that the level of INR at 1.4-2.3 is appropriate after the anticoagulation therapy in the MVR and DVR groups.

BACKGROUND:Studies have shown that fibrin glue can promote the survival of myoblast grafts, reduce infarct size and induce neovascularization of infarct zone. OBJECTIVE:To understand the condition of revascularization of infarcted heart muscle using endothelial progenitor cells combined with degradable fibrin glue materials. METHODS:A total of 27 Sprague-Dawley rats were randomized into three groups, 9 rats in each group:non-myocardial infarction group, immediate transplantation group and 1-week post-infarction transplantation group. Then, these three groups were sub-grouped into two groups, respectively:endothelial progenitor cells+fibrin glue group (experimental group) and fibrin glue group (control group). At 3 and 8 weeks after transplantation, the rats were sacrificed in each group. The revascularization and function of infracted heart muscle were observed by microscope, immunohistochemistry and echocardiography. RESULTS AND CONCLUSION:Under the microscope, there were some lax connective tissues between the heart and chest in the experimental groups, but no difference existed between the experimental and control groups. The heart structure was normal relatively and difficult to be distinguished between the experimental and control groups histological y and immunological y, and there was no angeioma, vascular malformation and tumor. The number of revascularization of heart muscle showed no difference between experimental and control groups as wel as between different experimental groups. Additional y, there was no significant difference in cardiac function between experimental and control groups. Although there are no positive results of endothelial progenitor cells, we wil modify and improve the strategy and believe that the celldelivery system is of benefit and efficacy.
