Antiretroviral treatment combined with nutritional support in acquired immune deficiency syndrome patients with comorbid malnutrition / 中华临床营养杂志

Objective To explore ways to improve effect of antiretroviral therapy in acquired immune defi-ciency syndrome patients with comorbid malnutrition, in an effort to enhance quality of life and reduce cost. Methods 126 AIDS patients with comorbid malnutrition were randomly divided into treatment group ( n=63) and control group (n=63). Patients in the treatment group were given nutrition support besides antiretroviral ther-apy (ART), while those in the control group only received ART. After 3 months, the two groups were compared in terms of body mass index, skinfold thickness, CD4+T cell count and human immunodeficiency virus load. Re-sults The two groups were comparable before treatment in BMI, skinfold thickness, CD4+T cell count and HIV load (P>0. 05). After treatment, the treatment group, compared with the controls, had higher BMI [ (23. 23± 3. 15) kg/m2vs. (17. 25±1. 83) kg/m2], thicker skinfold [ (42. 9±6. 8) mm vs. (34. 5±5. 2) mm in males;(97. 6±17. 4) mm vs. (92. 3±14. 7) mm in females], higher CD4+T cell count (χ2=12. 573, P<0. 01), and lower HIV load (χ2=8. 683, P<0. 01). Conclusion Nutrition support may improve treatment of AIDS patients with comorbid malnutrition, as manifested in better BMI, skinfold thickness, CD4+T cell count and HIV load.

Effect of local mild hypothermia on regional cerebral blood flow in patients with cerebral infarction assessed by 99mTc-ECD SPECT imaging / 实用医学杂志

Objective To investigate the frequency of lesions detection in patients with cerebral infarction (CI) with SPECT/CT. To investigate fluctuation of regional cerebral blood flow (rCBF) and its relationship with clinical symptoms. Methods Sixty-seven CI patients without cerebellar lesion were randomly selected. The rCBF in the regions of interest (ROI) was examined by SPECT/CT, which was collected from the frontal lobe, temporal lobe, parietal lobe, occipital lobe, thalamus, basal ganglia and cerebellum. The rCBF index was calculated. The association between fluctuation of rCBF index and clinical symptoms of patients was explored. Results There were 251 positive regions in all viewing regions , the total positive rate was 31.2%. The left side was 38.1%, while the right side was 24.4% (χ2=17.522,P 0.05). However, the average rCBF on the left parietal lobe was lower (P 0.05). rCBF≥0.7 is a clinical sign of abnormal ROI. Conclusion 30% of ROI of CI patients have lesions and the positive rate of the left side was higher. The biological rCBF values of all lobes were different. Therefore, rCBF index could be used to reflect whether the ROI is normal. rCBF≥0.7 could be used as a sign to quantitatively assess abnormal ROI in clinical practice.

Effects of Dendrobium Officinale Kimura et Migo on Cardiac Function and Changes of Blood Vessel in Rabbits with Coronary Heart Disease / 世界科学技术-中医药现代化

This study was aimed to observe effects ofDendrobium ofifcinaleKimura et Migo on cardiac function and changes of blood vessel in rabbits with coronary heart disease (CHD).Thirty clean grade healthy rabbits were randomly divided into 5 groups, which were the control group, model group,Dendrobium low-dose (DLD), middle-dose (DMD), and high-dose (DHD) group, with 6 rabbits in each group. Constrictor ring was implanted in the left coronary artery to establish CHD model in the model group, DLD, DMD and DHD groups. Intragastric administration of Dendrobium decoction at the dose of 10, 20, and 40 g·kg-1 was given to rabbits in the DLD, DMD and DHD groups once a day for 21 consecutive days, respectively. The same volume of normal saline was given to the control group and the model group. Detections were made on levels of IL-8, TNF-α, VCAM-1, ICAM-1, the expression of actin, changes of LVSP, LVEDP,±dp/dtmax, BPs, BPd and morphologic changes of blood vessel. The results showed that compared with the control group, levels of IL-8, TNF-α, VCAM-1, ICAM-1 and the expression of actin increased or significantly increased in the model group with statistical significance (P< 0.05, orP< 0.01); LVEDP increased significantly (P< 0.01). However, LVSP,±dp/dtmax and BPs reduced (P< 0.05, orP< 0.01). The blood vessel wall became thicker. Compared with the model group, IL-8, TNF-α, VCAM-1, ICAM-1 and the expression of actin in the DMD and DHD group reduced or significantly reduced with statistical significance (P< 0.05, orP< 0.01); LVEDP reduced significantly in the DMD and DHD group with statistical significance (P< 0.01). While, LVSP,±dp/dtmax and BPs increased or significantly increased with statistical significance (P< 0.05, orP< 0.01). The thickening of blood vessel wall was inhibited. It was concluded thatDendrobium ofifcinale Kimura et Migo can improve cardiac function, which may take effect by improving and inhibiting pathologic changes of blood vessel and alleviating vessel injury.

Study on the relevance between hypertension and serum uric acid in residents in Baise City of Guang-xi / 中华风湿病学杂志

ObjectiveTo realize the relevance between hypertension and serum uric acid (SUA) in residents in Baise City.MethodsTwenty one thousand,five hundred and eighty eight Baise residents were examined.The body weight,height,waist circumference,hip circumference,blood pressure(BP) were recorded and blood lipidlevels,blood glucoseand serum uric acid (SUA) were tested.The relevance between hypertension and hyperuricemia (HUA) was analyzed by multi-factor variance analysis,x2 test,t test,linear regression and Logistic regression analysis.ResultsHypertension prevalence rate was 31.5％,the frequency of HUA was 12.0％,and 5.8％ residents had both.For patients with both hypertension and HUA,when compared to those with normal serum uric level,their mean diastolic blood pressure(DBP) was(84±10),(72±6) mm Hg res-pectively,there mean systolic blood pressure (SBP) was(151±12),(127±6) mm Hg respectively,and pulse pressure (PP) was (50±12),(37±8) mm Hg respectively.The average BMI of those two groups was (23.9±2.6),(21.7±2.4) kg/m2 respectively.The average TC level was (6.0±1.3),(5.2±1.1)mmol/L respectively,the average TG level was(2.3±2.2),(1.5±0.7) mmol/L respectively,and the average LDL-C level was(3.4±1.3),(3.0±1.1) mmol/L respectively.All these parameters were higher than those people without hypertension or HUA(P＜0.01).However,the situation of HDL-C[ (1.2±0.4),(1.5±0.5)mmol/L] was the opposite (P＜0.01).Regression analysis had shown that age,BMI,waist-hip ratio,SUA,blood glucose,TC,TG,HDL-C and LDL-C were independent risk factors for hypertension,while people with HUA was 3.1 times more when compared to those without HUA.The prevalence rate of HUA in people with hypertension was 2.6 times higher than that of the control group.ConclusionHypertension and HUA are two public health problems that prevalent in the residents in Baise City.Obesity,high blood glucose level and hyperlipidemia are thebasis for the development of hypertension and HUA.Hypertension can be the cause of HUA and verse versa.They may have mutual interactions.The adverse effect of HUA on-cardiovascular system should be taken into consideration clinically.

Relationship between the prevalence of hypertension and metabolic syndrome in minority populations of Baise, Guangxi province / 中华内分泌代谢杂志

There were 3 000 Zhuangs,1 102 Miaos, and 1 283 Yaos in Baise City of Guangxi,who were enrolled in this population sampling stratfying survey. Height, weight, blood pressure, fasting blood glucose, and lipids were determined, and compared with those of 2 000 Hans of the same town. The prevalence of hypertension and metablic syndrome in Zhuang inhabitants was high, so were the disorders of glycemia and lipidemia, while in Miao and Yao minorities, the prevalences were comparatively lower. The awareness, treatment, and control of hypertension in these minorities were insufficient.
