Objective To explore the TCM syndrome distribution characteristics of central obesity hypertension patients; To analyze its correlation with urinary microalbumin/creatinine (MA/Cr) ratio; To provide some proof for an efficient way to control central obesity hypertension and prevent and cure its early renal injury with integrated TCM and Western medicine.Methods It was performed in a cross-sectional epidemiological study. The age, gender, height, weight, waist circumference, blood pressure, medical history and symptoms of 359 central obesity hypertension patients were collected in Shanghai. Then according to the four diagnostic methods, TCM syndromes were recorded. The urinary MA/Cr ratio, fasting blood glucose, fasting insulin and hs-CRP levels were detected.Results The urinary MA/Cr detectable rate in Shanghai among central obesity hypertension was 33.4% (120/359), men accounting for 56% and women 44%. Among central obesity hypertension patients, the HOMA-IR and hs-CRP level of urinary albumin group were significantly higher than those of normal group, with statistical significance (P<0.05). Among 359 central obesity hypertension patients, 140 people had phlegm-dampness syndrome, accounting for 39%, the largest part; 108 had liver-yang hyperactivity syndrome, accounting for 30%; 61 had yin-yang deficiency syndrome, accounting for 17%; 50 had yin-deficiency and yang-hyperactivity syndrome, accounting for 14%; the number of four TCM syndromes had statistical difference (P<0.05). Urinary MA/Cr ratio of the patients with phlegm-dampness syndrome was significantly higher than that of other three syndromes (P<0.05).Conclusion The incidence rate of early renal damage with central obesity hypertension patients is high in Shanghai area, and the early stage of renal damage is associated with insulin resistance and inflammatory reaction. Among central obesity hypertension, phlegm-dampness syndrome and liver-yang hyperactivity account for the majority, and patients with phlegm- dampness syndrome are more likely to have early kidney damage.

OBJECTIVE: To investigate the influence of hospice care on the life quality and psychological state of aged mortal inpatients. METHODS: Seventy-six aged patients were randomly divided into 2 groups (n=38). The research group was treated with hospice care, while the control group was treated with conventional nursing. Before and after more than one month of the interference, the quality of life, social support, satisfied degree, anxiety, and depression mood were investigated. RESULTS: All the indexes, such as total scale of life quality, appetite, spirit, sleep, family comprehension and coordination, recognition of cancer, attitude to therapy, and facial expression of the mortal inpatients after the interference, were raised and higher than those of the controls (P<0.05 or P<0.01). Life satisfaction index and the total scale of social support and subjective support, utilization ratio of support were raised and higher than those of the controls (P<0.05 or P<0.01). The level of anxiety and depression was decreased and lower than the control (P<0.05 or P<0.01). CONCLUSION Hospice care can raise the life quality, subjective support, utilization ratio of support and life satisfaction of aged mortal inpatients. It could decrease the negative mood, such as anxiety and depression and improve the psychological state.

In this study, we investigated the mechanism of linoleic acid-stimulated increase in intracellular calcium concentration ([Ca(2+)](i)) in pancreatic islet β-cells. Pancreatic islet cells were primarily isolated from rats and cultured for the experiments. The cells were loaded with Fluo-3/AM, the indicator of [Ca(2+)](i), and the intensity of Fluo-3 was measured using confocal microscope. The islet β-cells were identified by immunocytochemical staining with insulin antibody after recording. The drugs were given by perfusion system. The results showed that linoleic acid (20 μmol/L) stimulated [Ca(2+)](i) increase with the first peak increase and the following plateau increase. Linoleic acid-stimulated [Ca(2+)](i) increase was partly inhibited by removal of extracellular calcium and by transient receptor potential (TRP) channel blocker, La(3+), and it was totally blocked by exhaustion of intracellular calcium stores and inhibition of phospholipase C. It is concluded that linoleic acid stimulates [Ca(2+)](i) increase in islet β-cells through both extracellular calcium influx via TRP channels and calcium release from intracellular calcium stores.

OBJECTIVETo observe the effect of glycoprotein receptor blockade tirofiban in acute anterior myocardial infarction patients without ST segment resolution after primary percutaneous coronary intervention (PCI).

METHODSFrom April 2006 to April 2008, 157 acute anterior myocardial infarction patients without ST segment resolution after PCI were randomly allocated to tirofiban (intravenous bolus 10 microg/kg followed by intravenous infusion of 0.15 microgxkg(-1)xmin(-1) for 48 h, n = 80) or equal volume saline (control group, n = 77). Baseline characteristics, PCI features and clinical outcomes during hospitalization, left ventricular ejection fractions (LVEF) and major adverse cardiac events (MACE, including death, re-infarction and target vessel revascularization) at 30 and 180 days after discharge were compared between the two groups.

RESULTSThe baseline clinical characteristics were comparable between the two groups. Compared to control group, the MACE rates and re-infarction rates at 30 days (6.3% vs.18.2%, P < 0.05; 1.3% vs.9.1%, P < 0.05, respectively) and 180 days (10.0% vs.23.4%, P < 0.05; 2.5% vs.10.4%, P < 0.05, respectively) were significantly reduced in tirofiban group. LVEF value was significantly higher in tirofiban group at 30 days and 180 days compared with those in control group [(51 +/- 6)% vs. (46 +/- 8)%, P < 0.05; (57 +/- 7)% vs. (50 +/- 9)%, P < 0.05]. Hemorrhagic complications were similar between the two groups.

CONCLUSIONUse of tirofiban for acute anterior myocardial infarction patients without ST segment resolution after PCI is safe and can significantly improve 30 and 180 days clinical outcomes after discharge.

OBJECTIVETo study the effect of highly active antiretroviral therapy (HAART) on plasma levels of MSP and MCP-1 in AIDS patients.

METHODSForty Chinese AIDS patients were treated with HAART for 3 months and 84 German AIDS patients with HAART for 3 to 6 years. The pre-treatment and post-treatment plasma levels of MSP and MCP-1 were measured by enzyme-linked immunosorbent assay (ELISA), and their correlations with CD4+ cell counts and viral loads were analyzed.

RESULTThe mean levels of MCP-1 were significantly higher and MSP were significantly lower in HIV-infected patients compared with the HIV-negative controls (P <0.01). After HAART for three months, there were no significant changes in the levels of these cytokines. But after long-term HAART (for 3 to 6 y), the level of MCP-1 was increased and that of MSP decreased significantly (P<0.01). There was a negative correlation between MSP and MCP-1 levels, and the same for MSP level and CD4+ cell counts; while there was a positive correlation between MCP-1 levels and CD4+ cell counts.

CONCLUSIONThe changed plasma levels of MSP and MCP-1 are associated with HIV-1 infection and HAART may reverse the levels of these two cytokines.
