ABSTRACT
Objective Observation of the effects of Xinmailong injection on NGAL, hs-cTnT and RAAS in elderly patients with type 2 cardio-renal syndrome (CRS) , and EvaluatIon of the clinical efficacy and safety.Methods A total of 86 elderly patients who were collected from November 2015 to February 2017 were diagnosed as type 2 CRS in our department of geriatrics. According to the random number table method, they were randomly divided into two groups. Control group (43 cases) were treated with conventional medical therapy and xinmailong group (43 cases) were treated with xinmailong injection with a dose of 5 mg/kg twice a day for 15 days. The value of sneutrophil gelatin-associated apolipoprotein (NGAL) , hypersensitive troponin T (hs-cTnT) , brain natriuretic peptide (BNP) , plasma renin activity (PRA) , and angiotensin Ⅱ (Ang Ⅱ) , aldosterone (ALD) , left ventricular ejection fraction (LVEF) , six-minute walking test and other indicators were measured before and after treatment. Results After treatment, the value of NGAL, hs-cTnT, BNP, PRA, AngⅡ and ALD decreased in both groups, the value of LVEF and six-minute walking distance increased compared with those before treatment (P <0.05); The above indicators in the xinmailong group experienced a more significant alteration than in control group in the same period (P < 0.05); no side effect occurred in both two groups during the experiment. Conclusion Xinmailong injection can reduce the levels of NGAL, hs-cTnT and BNP in elderly patients with type 2 cardio-renal syndrome, improve heart and kidney function, and have curative positive effect and good safety. This study underlined the mechanism of Xinmailong injection may be related to the inhibition of RAAS activity.
ABSTRACT
ObjectiveTo observe the effect of resveratrol on the oxidative stress and antioxidant levels of different mitochondrial subpopulations in the skeletal muscle and insulin sensitivity of rats fed with high-fat diet.MethodsMale SD rats,aged 8 weeks,were divided into normal chow (NC) group,high-fat diet(HF) group,high-fat diet plus resveratrol ( HFR ) group.After intervention for 8 weeks,the impacts of resveratrol on oxidative stress levels and antioxidant enzymes activities in subsarcolemmal ( SS ) and intermyofibrillar ( IMF ) mitochondria from skeletal muscle as well as general and skeletal mascle insulin sensitivity were assessed.ResultsCompared with NC group, insulin sensitivity was significantly reduced while reactiveoxygenspecies (ROS)and malondialdehyde(MDA) levels in SS and IMF mitochondria increased in HF group ( all P＜0.01 ).In addition,antioxidant enzyme activities were significantly decreased in SS mitochondrial and increased in IMF mitochondrial ( both P ＜ 0.05 ).Compared with HF group,the insulin sensitivity in HFR group was significantly improved.Moreover,the activities of antioxidant enzymes in SS and IMF mitochondrial were increased,and the oxidative stress levels returned to normal ( P ＜ 0.05 ).ConclusionResveratrol notably improves the oxidative stress of different skeletal muscle mitochondrial subpopulations and insulin resistance in rats fed with high-fat diet.
ABSTRACT
Objective To investigate the characteristics of spinal injury caused by earthquake as well as to improve its therapeutic ability by comparatively studying the medical records of the inpatients with spinal injuries caused by Wenchuan earthquake and the inpatients with spinal injuries in peace time.Methods Medical records of inpatients with spinal injuries were extracted from 5.12 earthquake injury database(earthquake group) and medical records of the patients with spinal injuries firstly admitted to Daping Hospital between 2001 and 2007 were extracted from Chinese trauma database systems (control group).The epidemiological characteristics of the two groups were comparatively studied,including gender,age,injury causes,injury severity,treatments and outcomes.Results (1) The incidence of spinal injuries in the earthquake group was 16.7％ (524/3145),which was significantly higher than that (6.4％,682/10644) in control group (P＜0.01).(2) The female ratio in the earthquake group was significantly higher than that in the control group (57.4％:31.8％) (P＜0.01).(3) The age range of the earthquake group was (47.9 ±20.9) years.The wounded number presented an undulately rising trend in the earthquake group as the growth of age,while it showed a parabolic distribution in the control group.(4)The main causes for spinal injuries were crush injury (69.3％) and multi-factor injury (2.8％) in the earthquake group,while slipping up/fall (56.0％) and traffic accidents (23.6％) were the main causes in the control group.(5) There were 82.3％ of the earthquake group that were combined with multiple injuries and 48.1％ combined with at least two injuries,while the control group accounted for only 28.9％ and 12.0％ respectively.The NISS (new injury severity score) in the earthquake group was significantly higher than that in the control group [(11.6±8.8) points vs (7.5±4.8)points](P＜0.01).Meanwhile,the proportion of NISS≥16 in earthquake group was significantly higher than that in the control group as well (P＜0.01).(6) The length of hospital stay of the wounded in the earthquake group was significantly longer than that in control group [(40.5±24.5)d VS (23.9±26.7)d](P＜0.01).The treatment inefficiency rate in the earthquake group was higher than that in the control group (9.2％ vs 4.8％) (P＜0.01).Conclusions The earthquake group has a higher proportion of spinal injuries,female and elder cases,and combined injuries,a much severer injury,a longer length of hospital stay,and a higher treatment inefficiency rate,as compared with the control group.In the earthquake relief,more importance should be attached to salvage,diagnosis,transfer regulation and missed diagnosis,misdiagnosis and secondary injury should be avoided so as to improve the treatment level of the spinal injuries in earthquake.
ABSTRACT
To explore the relationship between serum thyroid stimulating hormone (TSH) level and obesity and nonalcoholic fatty liver disease (NAFLD) in euthyroid subjects, 1322 subjects were subjected to a questionnaire survey and physical examination. Fasting blood samples were collected to test serum TSH, plasma glucose and lipids. Fatty liver was diagnosed by type B ultrasonography. The relationship between serum TSH level and body mass index (BMI), percentage of body fat and NAFLD was analyzed. The results showed that serum TSH level was significantly higher in females than in males at the same group, and it was significantly higher in overweight group than in control group. Levels of body weight, BMI, waist circumference and percentage of body fat were increased in TSH >2.5 group compared to TSH ≤2.5 group in women. However, plasma lipids showed no significant differences. In males all the parameters showed no significant differences between two groups. Serum TSH was significantly correlated with body weight, BMI, waist circumference and percentage of body fat after adjustment for age in females. Multiple linear regression analysis revealed that percentage of body fat and BMI contributed significantly to the variance of TSH. Serum TSH level was significantly higher in nonalcoholic fatty liver group than in normal group in females. Multiple logistic regression analysis showed that TSH level was not the independent risk factor of NAFLD. Taken together the data suggest that serum TSH in normal range is significantly correlated with BMI and percentage of body fat in females. And the change of TSH level would not influence the prevalence of NAFLD.

ABSTRACT
Objective To analyze injury characteristics and treatment of hospitalized patients wounded in Wenehuan earthquake so as to provide references for medical rescue in disasters. Methods The study involved data of seismic patients from Trauma Database System Version 3.0 that collected clini-cal data of seismic patients admitted into West China Hospital of Sichuan University, Chengdu, and First and Second Hospitals of Deyang City. Trauma Database System Version 3.0 was developed by Research Institute for Traffic Medicine of PLA, Research Institute of Surgery, Daping Hospital, Third Military Medical University, Chongqing. A comparative analysis was done on patient distribution, injury severity and medical treatment. Results There were 826 qualified patients including 410 males and 416 females ( at age range of 1-102 years, mean 45.8 years). Of all, the patients at age of 31-60 years accounted for 50. 2%. The patients were mainly peasants (43.8%, 208/477), workers (15.7%, 75/477) and students (14.1%, 67/477). Blunt injury (53.2%), crush/bury injury (22.5%) and slip/fall injury were three main causes for injury. The patients for 92.1% were admitted into two hospitals of the City of Deyang within four days after earthquake, while 81.7% of patients were admitted into West China Hospital in Chengdu at days 3-9 after earthquake. Patients with bone injuries accounted for 75.3%. The patients had abbreviated injury score (AIS) for mainly 1-3 points, with incidence rate of se-vere multiple trauma ( ISS > 16 points) of 8.2%. Internal fixation was done in 120 patients ( 34. 1% ), debridement and suturing in 103 (29.3%), external fixation in 55 ( 15.6% ), extremity amputation in 22 (6.3%) and intracerebral surgery in 2 (0.6%). Conclusions The injuries are mainly induced by collapse of buildings during earthquake. Bone injuries are predominant injury type, with AIS of mainly 1-3 points and few severe multiple trauma. The results show that the patients receive late special treat-ment and slow evacuation, indieating necessity of strengthening capacity of early medical treatment and ef-fective evacuation during destructive natural disasters.
