0.05).Conclusion BNP and hsCRP may be involved in the occurrence and sustainment of atrial fibrillation.The serum levels of BNP and hsCRP may serve as independent indexes of atrial fibrillation.CK-MB may be not involved in the incidence and development of atrial fibrillation.

With the understanding of the immune inflammatory response in the pathogenesis of dry eyes, and the limitations of widely used artificial tears and numerous pharmaceuticals and methods to promote tear secretion, clinicians pay more attention to the therapies that can promote tear secretion actively. Acupuncture treatment for dry eye may meet this requirement.

OBJECTIVE:To establish an HPLC method for determining nicardipine hydrochloride(NCD) microspheres in cerebrospinal fluid(CSF) of rabbits by HPLC.METHODS:NCD microspheres were injected into the cistern of rabbits.Cerebrospinal fluid was sampled at different time points and NCD was separated on Agilent-Zorbax column at a flow rate of 1.0 mL?min-1 with column temperature of 30 ℃.The mobile phase consisted of methanol-water(75 :25,pH=6.0) and detection wavelength was set at 236 nm.RESULTS:The linear range of NCD was 2～128 ng?mL-1(r=0.999 8) with recovery of 98.07%.The RSD of intra-day and inter-day were both below 1.47%.The LOD was about 0.5 ng?mL-1.On 3～11 day after medication,the concentration of NCD fluctuated within(14.15?0.37) ng?mL-1.CONCLUSION:The method is simple,rapid and accurate for determination of NCD in cerebrospinal fluid of rabbits.

8-hydroxydeoxyguanosine (8-OHdG) in human urine is a marker reflecting oxidative stress and DNA oxidative damage. People spend 80%-90% of their life indoors; therefore, indoor air quality is directly related to human health. In this paper, the urinary 8-OHdG levels were presented in populations grouped by different demographic characteristics, lifestyle, occupational exposure, and health status, and elucidated indoor pollutants affecting human urinary 8-OHdG level, such as pollutants from outdoor sources, smoking, indoor combustion and cooking fumes, the chemicals in interior decoration materials, and building foundation soils. The article aims to provide a theoretical basis for predicting the impact of indoor air pollution on human health (DNA oxidative damage and related diseases) by measuring the concentration of 8-OHdG in human urine.

ObjectiveTo evaluate whether the junior high school students reared by their grandparents in 0～3 years old have more emotional and behavioral problems than their counterparts who reared by birth parents since birth. MethodsThis study was carried out to compare emotional and behavioral outcomes,using Youth Self-Report(YSR) between junior high school students reared by their grandparents in 0～3 years old and junior high school students reared by birth parents since their birth. ResultsTwo-sample test showed that the study group had significantly higher raw scores of the YSR sub-scale of somatic complaint[(2.93±2.83) vs (2.00±2.35),t=2.08,P＜0.05],social problems[(3.56±2.20) vs (2.42±1.99),t=3.15,P＜0.01],thought problems[(3.29±3.26) vs (2.16±2.29),t=2.30,P＜0.05],delinquency [(2.77±2.33) vs 2.01±1.60),t=2.19,P＜0.05] ,aggression[(7.89±6.32) vs 5.96±4.66),t=2.01,P＜0.05],externalizing problems [(10.67±8.07) vs (7.97±5.61),t=2.19,P＜0.05]and total problems [(42.64±22.76) vs (33.61±19.25),t=2.47,P＜0.05]than the comparison group. Analysis of covariance (ANCOVA) was used to control the effects of live events stress. The following analyses showed that the two groups showed no significant difference except for social problems (P＜0.05). ConclusionMany factors that affect mental health of the junior high school students. There is a significant differences in the social problems between the junior high school students reared by grandparents from infancy to the toddler stage and their counterparts. The grandparents should pay more attention to help their grandchildren developing social skills in their babyhood.

Medical histories and clinical data of 54 patients with Sheehan's syndrome (SS) in endocrine department from August 2008 to August 2011 were collected and analyzed retrospectively.47 cases of SS were accompanied by pituitary crisis.19 cases had been misdiagnosed previously.The average period from the obstetric events to diagnosis of SS was ( 12.36 ± 1.28 ) years.Intravenous drip of hydrocortisone was given for rescuing pituitary crisis.The average dosages of hydrocortisone for the first 24 hours and the second 24 hours were ( 83.93 ± 7.73 ) and (42.19 ± 5.13 ) mg respectively. 12 cases of SS presented transient psychosis after the regular dosage of oral glucocorticoid replacement.

Objective To investigate the relationship between the changes of serum total bilirubin(TBil) and hybrid muscle crea-tine kinase isozyme(CK-MB),and its clinical implication in neonates with hypoxic-ischemic encephalopathy (HIE). Methods The levels of TBil and CK - MB were measured in 49 neonates with HIE (15 mild cases, 20 moderate cases and 14 serious cases), and 31 normal neonates on the first day and the fourth day after birth. Results The levels of TBil on the first day after birth were significantly higher than those in normal neonates;the levels of TBil were correlated with the severity of HIE(P

[Objective]To analyze the clinical effect of intertrochanteric fractures treated with percutaneous proximal femoral nails(PFN).[Method]From January 2004 to May 2009,PFN using percutaneous technique was performed in 180 elderly patients of femoral intertrochanteric fractures(180 hips,80 males and 98 females),with mean age of 76 years(range from 57-99 years).According to Evans classification,12 cases were type Ⅰ,28 were type Ⅱ,62 were Ⅲa,20 were Ⅲb,49 were Ⅳ,9 were Ⅴ.Traction table and C-arm fluroscopic intensifier were used with close reduction and interlocking during the course of operation.[Result]One hundred and seventy two cases in 180 patients were followed up for 8 to 21 months with a mean of 13.5 months.Other 8 patients were lost to follow up after discharge.Of 172 patients followed up,166 cases' radiographs showed the callus during 6-8 weeks postoperatively,while they had a full range of hip motion as the original level.Partial weight bearing exercises were carried out since the 8th postoperative week.The time of clinical fracture healing was from 12 to 16 weeks,the rate of healing was 98.8%.In the function assessment of 172 patients the satisfactory rate reached to 87.8 percents.[Conclusion]Percutaneous proximal femoral nails is an ideal way for the treatment of intertrochanteric fractures in aged because of its simple procedure,minimal invasion,less fluoroscopy exposures,less complications,stable fixation,early fracture healing and satisfied functional outcomes.

Objective To explore the clinical experience of endovascular treatment for arteriosclerosis obliterans (ASO) of lower extremities.Methods Endovascular treatment were performed on 22 patients (26 limbs) suffering from ASO which were diagnosed by magnetic resonance angiography (MRA).The clinical efficacy after operation was analyzed.Results Twenty-two lower extremities of 18 patients successfully accepted endovascular treatment with 12 stents planted without major complications.Four cases failed to endovascular treatment and 2 of them converted to bypass surgery.The clinical symptoms of limb ischemia vanished or significantly improved after treatment.The ankle brachial index (ABI) of affected extremities increased from 0.35?0.13 (before operation) to 0.70?0.15 (after operation),P

To explore the effects of dietary conjugated linoleic acid(CLA) on body fat accumulation in male Wistar rats. The obese rat model was established by feeding high lipid forage. The rats were fed a semi-purified diet containing 0.5,1.0,3.0g?kg -1 CLA for 36 days. Low dose group, middle dose group and high dose group all could remarkably reduce the gain of body weight. Low dose group could reduce the body adipose, middle and high dose group could remarkably decrease the body adipose. There were significant differences in the fat and protein contents in the rats thigh between the control group and the group fed high dose CLA. These results suggested that CLA can reduce the body fat in obese Wistar rats.
