OBJECTIVEChina began providing antiretroviral therapy to people living with HIV/AIDS (PLWHA) in 2003. This study was to investigate the living conditions, including quality of life and happiness, and need for palliative care of end-of-life PLWHA in rural Henan.

METHODSOne hundred end-of-life AIDS patients were selected from Weishi, Zhenping and Tanghe counties in Henan, using convenience sampling. The World Health Organization Quality of Life for HIV (WHOQOL-HIV) BREF Chinese Version was used to measure the quality of life and the Memorial University of Newfoundland Scale of Happiness (MUNSH) was employed to measure subjective welfare. Qualitative interviews and focus group discussions were undertaken to learn about the palliative care provided and the specific needs of the end-of-life patients.

RESULTSPatients' overall quality of life was moderate (12.62±1.97). Highest scores were in the spirituality/religion/personal beliefs, higher than the average scores in the Chinese population (P<0.01), while psychological (13.58±2.06) and environment (12.50±3.28) domain scores were similar to the latter (P>0.05). Both independence (12.15±2.15) and physiological (14.04±3.16) domain scores were lower than the average of the people living with HIV/AIDS in other studies (P<0.01); however, all were in the moderate range. The average MUNSH score was 21.00±6.20, which was also moderate. The in-depth interviews indicated that the Henan Provincial Government's policy of treatment and care had a beneficial impact on end-of-life AIDS patients, although the care components could be improved.

CONCLUSIONSLiving conditions of the end-of-life AIDS patients were moderate, and the HIV/AIDS palliative care model used was beneficial to them. Care could be improved by assisting the family unit as a whole.

OBJECTIVETo observe protective effects of Shenmai (SM) injection on the delayed injury of the cerebral neurons in rat with intracerebral hemorrhage.

METHODRosenberg models of intracerebral hemorrhage was established and the effects of SM injection on the pathologic changes in neuronal structure, mitochondria-DNA(mtDNA)deletion, C-myc gene and expression PDGF-A gene in hippocampal CA1 areas, were investigated.

RESULTSM injection inhibited the apoptosis of pyramidal cells in the hippocampal CA1 areas, and decreased the degree of mtDNA deletion in the neurons in the injured area. SM injection had no effect on gene expression of C-myc at initial stage a intracerebral hemorrhage, but significantiy decreased the level of PDGF-A mRNA and prolonged the time of its expression.

CONCLUSIONSM injection might attenuate the delayed injury induced by intracerebral hemorrhage via regulating the expression of PDGF.

Objective To investigate the influence of mild hypothermia on the apoptotic protease activating factor-1 (Apaf-1) protein expression in the hippocampal CA1 area and learning and memory functions of rats after diffuse brain injury (DBI). Methods Forty-eight male Wistar rats were equally randomized into normal group, sham-operated group, brain injury group and mild hypothermia treatment group (n=12). Rats in the normal group did not receive any treatment; rats in the sham-operated group only received anesthesia, and incision and suture of scalp; rats in the brain injury group and mild hypothermia treatment group were induced the DBI models according to Marmarou method; and rats in the mild hypothermia treatment group were performed hypothermia with ice blanket and ice bag to control the rectal temperature within 30.0-31.0 ℃ for 2 h. After DBI for 2 weeks, the times of searching refuge platform and the protein expression of Apaf-1 were compared among the 4 groups. Results The times of searching refuge platform in the normal group, sham operated group, brain injury group and mild hypothermia treatment group were (10.1 ±1.9), (10.3±1.8), (3.8±2.3) and (6.9±1.1), respectively,with significant differences between each 2 groups (P<0.05). The protein expression of Apaf-1 in the brain injury group and mild hypothermia treatment group was obviously higher than that in the other groups (P<0.05), and significantly lower protein expression of Apaf-1 in the mild hypothermia rats was noted as compared with that in the brain injury rats (P<0.05). Conclusion Mild hypothermia might play a protective role by inhibiting neuronal apoptosis for rats with DBI through the Apaf-1 pathway,which can improve learning and memory abilities.

OBJECTIVEBased on the 2002 WHO health survey data, to explore the latent relationship among self-reported health level, the actual level of health, the social demographic characteristics and the risk factors, and to analyze the influence of the various surveillance indicators on self-reported health and the degree that the self-reported health explained the actual level of health.

METHODSField tests for various components of the World health survey were conducted in nine countries during 2002, including India, Brazil, Burkina, Hungary, Nepal, Russia, Spain, Tunisia, and Vietnam (29 971). The survey questionnaire included a self-assessment component and anchoring vignette component. The self-assessment component data was adjusted and eliminated the affect of "cut-point bias" by using the anchoring vignette component data, and then was used to build the structural equation model on the relationship among self-reported health level, actual health level, social demographic characteristics and the risk factors.

RESULTSIn the final structural equation model, "the actual level of health" = 0.80 × "the self-reported health level" + (-0.04) × "the social demographic characteristics" + (-0.08) × "the risk factors" (R(2) = 0.66), and "the self-reported health level" = (-0.70) × "the social demographic characteristics" + 0.10 × "the risk factors" (R(2) = 0.55). The standardized total effect of self-reported health to the actual level of health was 0.80, and that of the social demographic characteristics to the self-reported health and the actual level of health were -0.70 and -0.60, respectively. And the 16 items of self-reported health consisted of 8 dimensions; and sorted by the power of impact to the actual health level, they were mobility, pain and discomfort, sleep, cognition, feelings, self-care ability, visual capacity and interpersonal activities.

CONCLUSIONThere were significant linear correlation relationship between the actual level of health and the self-reported health, as well as between the self-reported health and the social demographic characteristics. And the self-reported 16 items used by the 2002 WHO health survey played an important role in the health evaluation of population.

OBJECTIVETo study the effect of polydatin on the expression level of miR-214 and liver function in atherosclerotic mice.

METHODSForty male ApoE(-/-) mice were randomly allocated into 4 groups (n=10), namely the model group, low- and high-dose polydatin groups, and simvastin group, with 10 male C57BL/6J mice serving as the normal control group. Mouse models of atherosclerosis were established by feeding the ApoE(-/-) mice with a high-fat diet. After 12 weeks of treatment, blood levels of glucose, lipids, AST, and ALT and the contents of T-SOD and MDA in the liver tissue were detected. The pathologies of the liver were examined with HE staining, and miR-214 expression in the liver was detected using quantitative real-time PCR.

RESULTSCompared with the normal control mice, the mice in the model group showed significantly increased blood glucose, serum TC, TG, LDL-C, ALT, and AST levels, and MDA contents in the liver (P<0.01), with significantly decreased serum HDL-C level and SOD and miR-214 levels in liver (P<0.01). Polydatin treatment significantly ameliorated such changes in blood glucose, serum ALT, AST, TC, TG, LDL-C, and HDL-C levels, and MDA, SOD, and miR-214 contents in liver tissue (P<0.05).

CONCLUSIONs Polydatin can reduce blood glucose and lipid levels and protect the liver function in atherosclerotic mice possibly by up-regulating the expression of miR-214 and T-SOD and down-regulating MDA in the liver.

OBJECTIVETo evaluate the predictive value of serum inhibin B (INH B) levels as an indicator of the presence of testicular spermatozoa in nonobstructive azoospermia.

METHODSForty patients with nonobstructive azoospermia (NOA), 20 patients with obstructive azoospermia (OA), and 10 fertile volunteers were involved in this study. A chemoluminescence method was used to measure the levels of FSH; Inhibin B was analysed by using sandwich enzyme-linked immuno-sorbent assay.

RESULTSPatients with nonobstructive azoospermia has significantly higher levels of serum FSH [(21.34 +/- 12.15) IU/L] and significantly lower levels of inhibin B [(53.15 +/- 58.74) ng/L] than patients with obstructive azoospermia [FSH: (3.94 +/- 1.52) IU/L, INH B: (162.49 +/- 78.38) ng/L, P < 0.01] and fertile volunteers [FSH: (4.27 +/- 2.84) IU/L, INH B: (228.49 +/- 110.68) ng/L, P < 0.01]. Mean serum inhibin B were significantly higher in patients with nonobstructive azoospermia who had spermatozoa on TESE than in those in whom no spermatozoa was found on TESE [INHB: (90.31 +/- 72.18) ng/L vs (19.54 +/- 20.38) ng/L, r = 0.528, P < 0.01], but mean FSH levels did not have similar predictive power (P > 0.05).

CONCLUSIONSerum INH B level seems to be more accurate than serum FSH in the prediction of presence of testicular spermatozoa in patients with nonobstructive azoospermia. Serum inhibin B determination may be substitute of TESE as a diagnostic index.
