BACKGROUND: The emphasis for preventing and treating cardiovascular diseases is to detect correlated risk factors. Among those accepted risk factors, whether serum uric acid (SUA) plays an independent role in the development of diseases is unknown.OBJECTIVE: To study SUA distribution and the prevalence of hyperuricemia, in middle-aged and elderly residents from the conjoining area between city and countryside in Guangzhou, and its association with other cardiovascular disease risk factors.DESIGN: Cross-sectional study.SETTING: Department of Cardiovascular internal medicine, Prevention and Health department, the Third Affiliated Hospital of Sun Yat-sen University.PARTICIPANTS: An investigation on the risk factors of cardiovascular diseases was carriedout among total 890 residents living at the conjoining area between city and countryside in Guangzhou in December 2002. A total of 642 persons including 152 men and 490 women who were above 55years and had complete data were involved, and all of them understood and agreed to the investigation.the-spot investigation. Systolic pressure, diastolic pressure, body height and body mass were measured, and then body mass index [body mass (kg)/body height (m)2] was calculated. High-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglyceride and total cholesterol were measured by endpoint method; SUA was measured by uricolase turbidimetric method.were defined as hyperuricemia. Diagnosis of hypertension was made according to the WHO/ISH 1999 Prevention and Cure Guidelines of Hypertension. Various kinds of dyslipidemia were diagnosed based on Prevention and Cure suggestions of dyslipidemia for Chinese (1997). Obesity was defined, according to 2002 International Obesity Special Working Group'skewness distribution and described by Median ± quartile. Spearson correlation analysis was used to determine the dependability between SUA and other selected cardiovascular risk factors. Binary Logistic regression analysis was done for further analysis.SUA and other cardiovascular risk factors.terolemia and hypertriglyceridemia in men and women were 30.3%, 30.8%;were (357.30±66.77) and (299.80±59.64) μmol/L respectively. SUA level was positive correlated with age in women (r=0.18, P < 0.01), but was not of SUA in men were 293.53, 357.30, 427.08 (μmol/L), and in women were 247.60, 299.80, 366.88 (μmol/L). Low-density lipoprotein cholesterol, total cholesterol, triglyceride, blood pressure and body mass index were positively associated with SUA, while high-density lipoprootein cholesteral was negtive correlated with SUA. In both men and women, triglyceride, total cholesterol, systolic blood pressure and body mass index were positively correlated with SUA significantly (r=0.09-0.35, P < 0.05-0.01), but highdensity lipoprotein cholesterol was negatively correlated with SUA significantly (r=-0.21, -0.25, P < 0.05, 0.01); diastolic blood pressure in men and low high-density lipoprotein cholesterol in women were positively correincluded to Logistic regression equation were age, body mass index and triglyceride [OR (95%CI): 1.048 (1.023-1.073), P=0.000; OR (95%CI): 1.156(1.096-1.219), P=0.000; OR (95%CI): 1.436 (1.224-1.684), P=0.000].uricemia is correlated with hypertension and various kinds of dyslipidemia.The elevation of SUA may be an important marker of cardiovascular dismay affect SUA mostly, and increase the risk for hyperuricemia.

Objective To study the effect of sodium ferulate (SF) on the expressions of nuclear factor-?B (NF-?B) and inhibitory ?B? (I?B?) in rat brain microvascular endothelial cells (BMEC) injured by hypoxia. Methods Brain microvascular endothelial cells from Wistar rat cerebral cortex were isolated and cultured, and then cultivated in 95%N_2 and 5% CO_2 for 12 h to induce hypoxia injury. The cells were divided into normal group, hypoxia group, and SF group. BMEC activity was assayed by MTT assay. Endothelin-1(ET-1) concentration was evaluated by radioimmunoassay.The expression of NF-?B and I?B? of BMEC were assessed by immunocytochemistry. Results The content of ET-1 in BMEC media was increased after hypoxia, while sodium ferulate (100 ?g/ml) significantly decreased the content compared with hypoxia group. Immunocytochemistry indicated I?B? expression were significantly decreased in hypoxia BMEC in consistent with NF-?B expression. Conclusion Sodium ferulate may significantly reduce NF-?B of hypoxia BMEC and nuclear translocation, and increase I?B? expression and BMEC activity. It is a potent inhibitor of NF-?B in endothelial cells, which might explain its beneficial effect on injured BMEC by hypoxia.

Objective To study the effects of the rehabilitation robot-assisted task-oriented training on the hand function in patients after stroke. Methods From June, 2015 to September, 2016, 35 inpatients suffering from stroke were randomly allocated to control group (n=17) and trial group (n=18). Based on the routine rehabilitation, the trial group accepted robot-assisted task-oriented training, while the control group accepted therapist-assisted task-oriented training, for two weeks. They were measured the active range of motion (AROM) of fingers, assessed with fingers motor of Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) invovled with hands before and after train-ing. Results The inpatients dropped three in the control group, two in the trial group. AROM of extension and flexion of all the fingers, the AROM of extension and total of three fingers of thumb, index and middle, and the total AROM of each finger improved in the trial group af-ter training (t>2.937, P<0.05), while the AROM of extension and flexion of all the fingers, AROM of extension, flexion and total of the fin-gers of thumb, index and middle, total AROM of the fingers of thumb, index and little improved in the control group after training (t>2.528, P<0.05);the AROM of extension and total of the fingers of thumb, index and middle, and the total AROM of fingers of thumb and index im-proved more in the trial group than in the control group (t>2.535, P<0.05). The scores of mass flexion, mass extension, opposition, cylinder grip, spherical grip and total score of FMA improved in the trial group after training (Z>2.000, P<0.05), while the scores of mass extension, opposition and the total score of FMA improved in the control group after training (Z>2.000, P<0.05). There was no significant difference between the two groups on the items and total scores after training (P>0.05). The scores of feeding, dressing, toilet transfers, bathing, groom-ing of MBI and the total score of them improved in the trial group after training (Z>2.041, P<0.05), while the total score of MBI improved in the control group after training (Z=-2.527, P<0.05). There was no significant difference between the two groups in the items and total scores after training (P>0.05). Conclusion The rehabilitation robot-assisted task-oriented training can improve AROM of hemiplegic fingers and grip function.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Mitochondria are morphologically dynamic organelles which undergo fission and fusion processes. Our previous study found that arterial constriction was always accompanied by increased mitochondrial fission in smooth muscle cells, whereas inhibition of mitochondrial fission in smooth muscle cells was associated with arterial relaxation. Here, we used the typical vasorelaxants, verapamil and phentolamine, to further confirm the coupling between arterial constriction and mitochondrial fission in rat aorta. Results showed that phentolamine but not verapamil induced vasorelaxation in phenylephrine (PE)-induced rat thoracic aorta constriction. Verapamil, but not phentolamine, induced vasorelaxation in high K(KPSS)-induced rat thoracic aorta constriction. Pre-treatment with phentolamine prevented PE- but not KPSS-induced aorta constriction and pre-treatment with verapamil prevented both PE- and KPSS-induced aorta constriction. Transmission electron microscopy (TEM) results showed that verapamil but not phentolamine inhibited KPSS-induced excessive mitochondrial fission in aortic smooth muscle cells, and verapamil prevented both PE- and KPSS-induced excessive mitochondrial fission in aortic smooth muscle cells. Verapamil inhibited KPSS-induced excessive mitochondrial fission in cultured vascular smooth muscle cells (A10). These results further demonstrate that arterial relaxation is coupled to inhibition of mitochondrial fission in arterial smooth muscle cells.
