Sleep deprivation (SD) has been taken as an independent predictor for cardiovascular risks, which was closely related to the increased morbidity and mortality in coronary heart disease (CHD). In this article, after reviewing the impact of modern medical method sleep deprivation on CHD and studies on principle method recipe medicines for preventing and treating CHD, the authors observed the autonomic nerve dysfunction, hormonal metabolism dysfunction, endothelial dysfunction and inflammatory responses after sleep deprivation, which can cause or aggravate CHD. On the basis of the traditional Chinese medicine theories of "heart dominating the blood and vessels and the mind", the authors considered that traditional Chinese medicines can tonify heart and soothe the nerves, reducing all of the risk factors through multi-target and multi-pathway, and improve sleep and decrease the risk factors caused by sleep deprivation, which provides a new idea for the prevention and treatment of CHD.

OBJECTIVE:To improve the information system of Out-patient pharmacy intravenous admixture center (OUIVA) to improve the pharmaceutical service rendered to the transfusion patient and ensure the safety of drug use. METHODS:The defi-ciency in OUIVA information system of our hospital were analyzed,in which improvement was made with respect to ungrouped doctor’s orders,inconsistency between the total doses charged and the prescribed doses and the error of transfusion days that occurred fre-quently. The conformity rate of out-patient fluid transfusion prescriptions and the time of patients’waiting for transfusion before and after the improvement were compared and evaluated. RESULTS:Improvement was made to OUIVA information system through the optimization of transfusion process,the application of condition limit,the adding of logical operation and verification and the other measures. After improvement,the unconformity rate of out-patient prescriptions in our hospital descended from 11.24% in 2013 to 3.69% in 2014,with an obvious increase in the accuracy rate of dispensing for fluid transfusion;and the time of patients’waiting for transfusion was shortened from 30-40 min to 15-20 min,with an increase in the degree of satisfaction of transfusion patients. CONCLUSIONS:The OUIVA information system can reduce the errors of drug dispensing for fluid transfusion and improve pharmaceutical services.

The progressive injury of retinal ganglion cells ( RGCs) is a common occurrence in several eye diseases, which ultimately may lead to irreversible blindness. Currently, there are still no effective or ideal treatments for it in practice, however some recent studies show that stem cell transplantation may provide a promising new idea for neuroprotection and replacement of retinal ganglion cells. This paper will review the research progress of stem cell transplantation-based treatment.

AlM: To investigate the relationship among carotid atherosclerosis, homocysteine ( Hcys ) and anterior ischmic optic neuropathy( AlON) .METHODS: Sixty-five AlON patients enrolled in AlON group and 70 non - AlON controls enrolled in control group. All the participants in 2 groups were examined by carotid artery color doppler flow imaging to evaluate the incidence of carotid atherosclerosis. Plasma levels of Hcys, vitamin B12 and folate were measured by automatic biochemical analyzer. The incidence of carotid atherosclerosis, plasma levels of Hcys, vitamin B12 and folate were compared statistically between AlON and control group.RESULTS: Fifty - six AlON patients ( 86%) exhibited carotid atherosclerosis, which was found in 43 control subjects ( 61%) . Fifty - nine AlON patients ( 91%) exhibited increased plasma levels of Hcys compared with that in 38 control subjects ( 54%) . Lowered vitamin B12 was found in 37 patients with AlON ( 57%) and in 43 control subjects ( 61%) . Lowered folate was found in 54 AlON patients ( 83%) and in 32 control subjects ( 46%) . The incidence of atherosclerosis in carotid artery ( P =0. 001), mean Hcys level (P=0. 0005) and lowered folate ( P = 0. 0006 ) were different statistically between AlON group and control group. Mean vitamin B12 level was indifferent between AlON group and control group ( P=0. 0722). Logistic regression analysis showed that carotid atherosclerosis was an a risk factor for AlON (OR=1. 312, 95%CI:0. 927~1. 772), whereas elevated Hcys level (OR=2. 378, 95% CI: 1. 479 ~ 3. 821 ) was also shown to be significant risk factor for AlON. CONCLUSlON: Carotid atherosclerosis and elevated Hcys were related with AlON. Reducing above-mentioned risk factors related to thrombus may be crucial to the prevention and cure of AlON.

Objective Investigate the effect of insomnia on cardiovascular disease factors and offer the experimental evidence for treating cardiovascular disease with traditional Chinese medicine tranquillization methods. Methods Sixteen Wistar rats were randomly divided into two groups named sleep deprivation ( SD ) group and normal control check( CC) group.Body weight and electrocardiogram were recorded and serum concentrations of melatonin ( MT) , endothelin-1 (ET-1), IL-6 and TNF-αwere tested before SD and 2 days, 5 days, 7 days after SD.Results Body weight decreased in SD group while increased in CC group.Compared with CC group, body weight of SD rats decreased significantly in 5 days and 7 days after SD( P <0.05) .Compared with CC group, TNF-αincreased significantly in 5 days (P <0.05).With the time, heart rate accelerate and QTc were prolonged, MT decreased while ET-1, IL6, TNF-αincreased significantly in 7 days after SD (P <0.05).Conclusion Long term insomnia would decrease body weight and MT, while increase heart rate, QTc, ET-1 and inflammatory factors, which increase cardiovascular disease factors.It provided the experimental evidence for the study on traditional Chinese medicine tranquillization methods in the treatment of cardiovascular disease.

Objective To investigate the psychological characteristics of neurosis and strategy for nursing care.MethodsThe effects of psychological nursing on neurosis were analysed retrospectively.ResultsPsychological nursing could decrease the time in hospital in patient with neurosis except somatoform disorders other than hypochondriasis.ConclusionPsychological nursing is important to neurosis.

Objective To analyze the monitoring results of human and animal plague in Zhangye city from 1982 to 2011,and further explore the prevention and control policies and measures to control the spread of the disease.Methods The trends of human and animal plague were studied by retrospective survey in Zhangye city.Information of animal and human plague epidemic and prevention and control measures were collcoted and assessed with epidemiology methods,and the density of rodents,the rodents infected with flea,flea index and other indicators were calculated.Results 1982-2011,there were 6 cases of human plague incidence of 6 cases,of which 2 cases cured,4 cases died,the mortality rate was 67％; detection of Yersinia pestis from the captured 5167 animals was 93 strains from 1982 to 2011,the detection rate was 1.80％; 29 840 various vector insects were collected from the body surface of the 5167 animals captured,21 206 hole dries,and three marmot dens.A total of 7050 groups of Marmota parasites and hole stem fleas were inspected,52 strains of Yersinia pestis were isolated,and the average detection rate was 0.74％; 3912 marmot serums were detected,178 were positive,and the positive rate was 4.55％.Conclusions The prevention and control of plague is still very grim in Zhangye city.It is recommended to take publicity,education and active surveillance measures in the future to deal with emergencies and other.

OBJECTSTo investigate the distribution of vitamin D receptor (VDR) genotypes among the Hans of a lead contaminated mine in Shanxi and explore the relationship between blood lead levels and the genetic polymorphism of VDR gene.

METHODSVDR genotypes were determined by polymerase-chain-reaction and restrictive fragment length polymorphism (PCR-RFLP) and the blood lead level was measured by using the graphite furnace atomic absorption spectrometry in a population of 120 pre-school children aged 5 - 6 years who were from the mine kindergarten and were unrelated Hans. An environmental questionnaire in relation to blood lead level was filled for each subject.

RESULTS(1) The gene distribution of the VDR phenotypes in these children was VDRBB, 1.7%; VDRBb, 9.2%; VDRbb, 89.2%. (2) The mean blood lead level of the children who had VDR B allele [(0.910 8 +/- 0.265 0) micromol/L] was significantly higher than that whose VDR genotype was bb [(0.740 1 +/- 0.270 1) micromol/L (mean +/- standard deviation)] (t = 2.155, P < 0.05). (3) Many factors were found to affect the blood lead levels, such as the VDR genotype, the type of fuel, educational level of mothers and so on. After controlling the possible confounding variables by multiple regression, the contribution of the VDR phenotype to the blood lead levels was still statistically significant.

CONCLUSIONThese results indicated that the frequency distribution of the VDR genotype in these children was apparently different from that in Caucasians who had high frequencies of VDR B. The results also indicated that the individuals carrying the VDR B allele were more susceptible to lead poisoning.

In this study, the general bacterial probe and specific cellulolytic bacterial probes were used to quantify the bacteria in rumen. The total RNA were extracted and then hybridized with general bacterial probe after a dilution of concentration. The result showed that there was a high correlation between the hybridization signal and the dilution of total bacterial RNA. Based on the result above, the quantities of three cellulolytic bacteria in rumen sample were detected. The comparative RNA percentage of three cellulolytic bacteria to total bacterial RNA were similar to the previous reports. It can be concluded that the quantification of bacteria in rumen could be conducted by this approach, and which could be used in future research.

Many bioactive peptides from neural and endocrine tissue are amidated at C-terminals,which is essential for their activities.The ?-amide comes from post-translational modification that is catalyzed by ?-AE (?-amidating enzyme) or PAM (pepdilylglycine ?-amidating monooxygenase).The gene encoding ?-AE was amplified with PCR and cloned into the plasmid pET-30a.After the recombinant plasmid pET-A was transformed into E.coli BL21,the ?-AE was expressed and purified by the Ni2+affinity chromatography,which has the ability catalyzing Dns-Tyr-Val-Gly to Dns-Tyr-Val-NH2.It identified that the recombinant protein producing by E.coli BL21 is ?-AE,which will benefit for studies of amidation at the C-terminals of peptides.
