Objective To investigate infection status and distribution characteristics of human immunodeficiency virus (HIV)infection among voluntary blood donors in Xiangyang area in 2009-2014,and provide evidence for re-cruiting blood donors from low-risk population. Methods Blood specimens of 326 856 voluntary blood donors in Xiangyang area between January 2009 and December 2014 were detected anti-HIV with enzyme linked immunosor-bent assay(ELISA),positive specimens in HIV screening were performed confirmatory testing,epidemiological analysis was conducted on the positive detection results.Results 41 (0.13‰ )voluntary blood donors were con-firmed positive for HIV in Xiangyang area,positive rate among each year was significantly different (χ2 =27 801.87,P<0.01). Except marital status and infection routes,difference in positive rates among donors of dif-ferent gender,age,area,occupation,educational attainments,and number of blood donation were all significantly different(all P<0.01). Among HIV-infected voluntary blood donors,87.80% were male,41.46% and 31.71%were aged between 18-25 and 36-45 respectively,56.10% were through heterosexual transmission,and 43.90%were through male homosexual transmission. The percentage of workman and public service personnel infected with HIV were high,accounting for 21 .95% and 17.07% respectively,60.97% of confirmed positive HIV were from city area,56.10% only received junior middle school/technical secondary school education,65.85% of HIV-infec-ted persons were infected at the initial donation.Conclusion In order to ensure blood safety,blood center should in-crease publicity efforts,carry out health consultation before blood donation,and recruit blood donors from low-risk populations,nucleic acid detection should be carried out to shorten HIV detection window period.

Methods 120 cases of patients with carotid endarterectomy were randomly divided into the observation group and the control group with 60 patients in each group, in the control group, before surgery, the nurse of ward gave routine preoperative nursing care and health education.In the observation group, in addition to routine preoperative care and health education, there were preoperative visits by intensive care unit nurses, the anxiety level was compared 1 day before surgery and 2 to 3 days after surgery. Besides, the cooperation degree of patients was also compared. Results There was no significant difference in anxiety levels in the observation group, but there was significant difference in anxiety levels in the control group, there was significant difference in patients coordination degree between two groups. Conclusions Preoperative visits by intensive care unit nurses can reduce the anxiety level of patients, shorten hospital stay and promote early recovery of patients.

Objective To observe the clinical efficacy of Tiao Ren Tong Du (regulating the Conception Vessel and unblocking the Governor Vessel) needling method in treating post-stroke insomnia and the change of Pittsburgh Sleep Quality Index (PSQI) after treatment, and to discuss the effect of this needling method on post-stroke insomnia. Method Ninety post-stroke patients were randomized into a treatment group, a control group and a Western medicine group. For the treatment group, points from the Conception and Governor Vessels were selected as the major points; for the control group, conventional needling method was adopted; for the Western medicine group, Zopiclone was prescribed. After intervention, the clinical efficacies and PSQI scores were investigated and compared. Result After intervention, the effective rates of the three groups were equivalent (P>0.05), the recovery rate of the treatment group was significantly higher than that of the control groups (P<0.05,P<0.01), and the PSQI scores were significantly changed in all three groups (P<0.05); the one-month and 3-month follow-ups showed insignificant changes of PSQI score in the treatment group compared to that right after the intervention (P>0.05); in the Western medicine group, the one-month follow-up showed significant difference in PSQI score compared to that right after the intervention (P<0.05); in the control group, there was a significant difference in PSQI score between the one-month follow-up and 3-month follow-up results (P<0.05). Conclusion The clinical efficacies of acupuncture methods and oral administration of Zopiclone are equivalent in treating post-stroke insomnia, but Tiao Ren Tong Du needling method can produce a higher recovery rate and better long-term efficacy.

Methods T lymphocyte subsets and CD + 4 T helper subsets (including T helper 1 and T helper 2 cells) in peripheral blood from 30 cases with URSA and 24 healthy women (controls) were detected by enzyme-linked immunospot assay (ELISPOT). Results The percentage of CD + 4 positive T lymphocytes in URSA group was higher than that in the controls (60% vs 45%, P

Objective To investigate the changes of homocysteic acid (Hcy) and C-reactive protein (CRP) levels in blood plasma of elderly patients with coronary heart disease and elucidate the risk factors of elderly patients with coronary heart disease.Methods 90 elderly patients with coronary heart disease were divided into 3 groups:stable angina pectoris group (SAP)(n=30),unstable angina pectoris group(UAP)(n=30),acute myocardial infarction group(AMI)(n=30).30 healthy elderly persons elder than 60 years old were enrolled as control group.Venous blood of all persons was harvested during empty stomach and plasma was separated.Then plasma Hcy and CRP were determined.Results The TC and TG levels in the three elderly coronary heart disease groups were significantly higher than those in control group (P

Objective To observe the preventive and therapeutic effects of Sagittara Sagittifolia L.Xiao-Zhi Pills on nonalcoholic steatohepatitis(NASH) in rats.Methods Rat NASH models were established and the rats were divided randomly into five groups: the normal group,model group,high-dosage group and low-dosage groups of the treatment,and Dongbao Gantai positive drug group.Histopathological changes of the liver were observed.The levels of MDA,superoxide dismutase(SOD),and NO(nitric oxide) in the liver homogenate were determined.Expressions of cyclooxygenase-2(cox-2) and inducible nitric oxide synthase(iNOS) in the liver were determined with immunohistochemical technique.Results In model group,extensive adipose degeneration and inflammatory cell infiltration were found in the liver.Compared with those in normal group,SOD activities in model group were obviously decreased(P

[Objective] To explore the relativity between sPG and gastritis of H.pylori. [Method] Select 73 cases of chronic gastritis correctly diagnosed by gastric microscope and pathology, among which, 36 were chronic atrophic gastritis and 36 chronic superficial gastritis. 49 cases of positive H.pylori were administered with Lizhu Weisanlian tablets, measure the sPG before and after treatment. [Result] In the infected cases of H.pylori, PG Ⅰ was similar between atrophic gastritis and superficial gastritis; for PG Ⅱ value, atrophic gastritis group was more than superficial gastritis group, positive H.pylori patients higher than negative ones; PGR(PG Ⅰ/PG Ⅱ) was lower in atrophic gastritis group than superficial one, so was in positive H.pylori than negative one. After anti-H.pylori treatment, 87.75% patients were removed H.pylori, where the PG Ⅰ rose, PG Ⅱ lowered, PGR rose in atrophic gastritis group; in the superficial one where the H.pylori was not removed, no changes happened to PG Ⅰ, PG Ⅱ and PGR. In superficial gastritis group where the H.pylori was not removed, PGR rose. [Conclusion] H.pylori infection is correlated with sPG. Serum PG Ⅰ, PG Ⅱ and PGR have definite value in early diagnosing H.pylori concerned atrophic gastritis. PGR can be an index to evaluate the removal efficacy of H.pylori.

[Objective] To discuss the effect of the community chronic disease management mode which combines physical identification and“preventive treatment”in control of GLU and TG of diabetes. [Method] 300 patients with T2 DM were randomly divided into the control group and intervention group with 150 patients in each group. The intervention group were physical y identified, and the management mode based on theories of“preventive treatment”including health education, diet control, exercise and medication used in the intervention group according to the result of physical identification, while the general management was used in the control group. 1 year later, changes of patients ’GLU and TG were observed. [Result] The community chronic disease management mode which combines physical identification and “preventive treatment”can improve T2 DM patients’GLU and TG, and reduce the GLU and TG of patients with QiXu, YangXu, and ShiRe types of physique. [Conclusion] The community chronic disease management mode which combines physical identification and“preventive treatment”is proved to be effective, and it improves the management of diabetes in communities.

Objective To observe the preventive and therapeutic effects of Sagittara Sagittifolia L. Xiao-Zhi Pills on nonalcoholic steatohepatitis (NASH) in rats. Methods Rat NASH models were established and the rats were divided randomly into five groups: the normal group, model group, high-dosage group and low-dosage groups of the treatment, and Dongbao Gantai positive drug group. Histopathological changes of the liver were observed. The levels of MDA, superoxide dismutase (SOD), and NO (nitric oxide) in the liver homogenate were determined. Expressions of cyclooxygenase-2 (cox-2) and inducible nitric oxide synthase (iNOS) in the liver were determined with immunohistochemical technique. Results In model group, extensive adipose degeneration and inflammatory cell infiltration were found in the liver. Compared with those in normal group, SOD activities in model group were obviously decreased (P<0.01), the contents of MDA and NO were obviously increased (P<0.01), and the expressions of cox-2 and iNOS proteins were obviously increased (P<0.01). Compared with those in model group, the activities of SOD in treatment groups were obviously increased (P<0.01), the contents of MDA and NO were obviously decreased (P<0.01), and the expressions of COX-2 and iNOS proteins were obviously decreased (P<0.01). The effect of high-dosage group was more obvious than that of Dongbao Gantai group (P<0.05). Conclusion Sagittara Sagittifolia L. Xiao-Zhi Pills can effectively prevent and treat nonalcoholic steatohepatitis in rats, and its mechanism may be associated with ameliorating hepatocellular steatosis, removing the free radicals and enhancing the anti-oxidation and anti-inflammation capability.
