Objective To investigate the effects of partial body weight supported treadmill training (BW- STT) on post-stroke depression (PSD) and on patients' quality of life.Methods Sixty patients with PSD were re- cruited and divided into a training group (n=30,male 17,female 13) and a control group (n=30,male 16,fe- male 14).All patients were treated with routine internal medication and rehabilitation.The patients of the training group also received BWSTT in addition to their routine treatment.All patients' neurological impairment was evaluated using the Modified Edinburgh-Scandinavian Stroke Scale (MESSS).The Hamilton depression scale (HAMD) was used for evaluating the degree of depression.The Fugl-Meyer scale and the Barthel index were used to assess ambula- tion and balance,and facility in the activities of daily living.All patients were assessed before and after the treat- ment.Results After four weeks of treatment,depression in the training group had improved significantly more than in the control group.Conclusion BWSTT intervention is very important for patients with PSD:it can reduce the degree of depression and improve the quality of life.

Objective To investigate the effect of partial body-weight supported treadmill training ( PBW- STT) on function of lower limbs, walk function, ADL performance and quality of life of hemiplegic patient induced by cerebral infarction. Methods A total of 132 cerebral infarction patients were divided into a control group (n = 69) and a training group( n = 63) randomly. Both groups accepted routine rehabilitation therapy, and the training group accepted PBWSTT at the same time in addition. Both groups were evaluated with regard to their walking ability, func- tion of lower limbs, ADL performance and their quality of life by using Functional Ambulation Category (FAC) , Fugl-Meyer assessment (FMA) , Barthel index (BI) and SF-36 before and after rehabilitation treatment. Results The function of lower limb, walking ability, ADL performance and the quality of life of both groups were improved significantly after treatment, and those in the training group were improved to a significantly greater extent than those in the control group ( P

BACKGROUNDVisfatin, a visceral fat-derived adipocytokine, plays a significant physiological function in lipid metabolism. However, the precise function of visfatin and its regulation by thyroid hormones are still unknown. This study observed the plasma visfatin concentrations in subjects with hyperthyroidism and hypothyroidism in vivo, and investigated the possible regulation mechanism between visfatin and tri-iodothyronine (T3) in vitro as a further interpretation.

METHODSThe experiment in vivo included clinical subjects (57 patients with thyroid dysfunction and 29 euthyroid healthy volunteers) and an animal model (24 Wistar rats). All subjects were divided into hyperthyroidism, hypothyroidism and euthyroidism groups, with plasma thyroid hormones, thyrotropin, visfatin and triglyceride concentrations determined. Visfatin mRNA expression in visceral fat and liver of rats was detected by quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR). The experiment in vitro studied 3T3-L1 cells and visfatin mRNA expression under nine different T3 concentrations (0, 0.1, 0.25, 0.5, 1, 5, 10, 20, 100 nmol/L) using quantitative real-time RT-PCR.

RESULTSClinical subjects and animal models showed elevated plasma visfatin concentrations in the hyperthyroidism group (20.466 ng/ml (15.263, 26.795 ng/ml) and (1209.164±165.292) ng/L) and hypothyroidism group (12.457 ng/ml (11.115, 15.454 ng/ml) and (1205.425±109.200) ng/L) compared to euthyroidism group (6.891 ng/ml (5.888, 8.803 ng/ml) and (926.650±54.002) ng/L, P<0.001). For animal models, visfatin mRNA expression in visceral fat in the hyperthyroidism and hypothyroidism groups increased about 3.33-fold and 1.98-fold compared to the euthyroidism group (P<0.001), which was positively correlated with plasma visfatin concentrations (r=0.713, P<0.001). However, no significant group difference (P>0.05) and correlation (r=0.121, P=0.572) was found in the liver. T3 induced a remarkable increase of visfatin mRNA expression in 3T3-L1 cells at low concentrations (0-0.5 nmol/L T3) followed by a sharp decrease at higher concentrations (0.5-100 nmol/L T3), with an inflection point at 0.5 nmol/L T3.

CONCLUSIONElevated circulating visfatin levels in subjects with hyperthyroidism and hypothyroidism are possibly due to an increase of visfatin mRNA expression in visceral fat, and a nonlinear regulation mechanism on visfatin mRNA expression under various T3 concentrations might be involved.

Objective To retrospectively explore the prevalence of cardiovascular disease (CVD) in inpatients with chronic obstructive pulmonary disease(COPD)in Beijing.Methods The COPD patients who were discharged from the General Hospital of the Liberation Army,Peking Union medical college Hospital and Beijing Hospital between January 1st,2000 to March 20th,2010,were investigated.The prevalence of CVD were calculated.The tendency of the prevalence of CVD by age or discharge year and the difference of the prevalence of CVD between male and female were estimated by using chi-square analysis.Results There were 4960 COPD patients who were in accordance with the inclusion criteria with 3570 males and 1390 females.The mean age was 72.2±10.4 years.Of the COPD patients,48.8% were diagnosed as cardiovascular diseases.The age-adjusted over-all prevalence of CVD was 26.4%.Chronic pulmonary heart disease and other disease of pulmonary artery(15.8%)was the most frequent diseases,followed by heart failure(13.6%),ischemic heart disease (10.6%).In COPD patients,male was more likely to have angina,pulmonary heart disease and other disease of pulmonary artery and acute kidney failure (P＜0.05),while less likely to get arrhythmia (atrial fibrillation/atrial flutter),heart failure,pulmonary embolism,hypertension and diabetes mellitus (P＜0.05).The prevalence of arrhythmia increased with age,however,the ischemic heart disease and heart failure decreased.The proportion of CVD decreased in male patients while increased in females.Conclusion The overall prevalence of CVD comorbidities was 48.8% in 4960 patients with COPD who were older than 40 years in Beijing.There were differences among the groups of various age and sex in the distribution of CVD comorbidities frequencies year by year.

To investigate the effect of vitamin D in pathogenesis and clinical treatment of patients with immune thrombocytopenic (ITP), ELISA was used to detect the level of 25-hydroxylate vitamin D3[25(OH)D3] and 1,25-dihydroxyvitamin D3[1,25(OH)2D3] in peripheral blood from 45 ITP patients and 30 normal controls. Vitamin D receptor (VDR) mRNA expression was detected by RT-PCR. The results showed that the levels of 25(OH)D3 (10.6 ± 7.7 ng/ml) and 1,25(OH)2D3 (69.9 ± 29.0 pg/ml) in peripheral blood of the initial ITP patients were lower than those in peripheral blood of normal controls (13.7 ± 9.1 ng/ml, 87.3 ± 19.9 pg/ml) (P < 0.05). The expression of VDR gene obviously increased in peripheral blood of initial ITP patients (1.588 ± 0.127), as compared with that in peripheral blood of normal controls (1.055 ± 0.734) (P < 0.05). It is concluded that vitamin D level and its receptor expression may play an important role in ITP, and vitamin D and its similarities may be a new agent to treat patients with ITP.

OBJECTIVETo investigate the correlation between fetal chromosomal abnormalities and the characteristic features of prenatal ultrasound findings.

METHODSA total of 510 cases were underwent chromosome examination by amniotic fluid or cord blood analysis to identify fetal chromosomal abnormalities. The correlation between the abnormalities and the characteristics of the prenatal ultrasound findings was analyzed.

RESULTSFifty-three cases of abnormal karyotypes were detected with a positivity rate of 10.2%. Of these cases, 32 cases had chromosome number abnormalities, including 15 with 21-trisomy, 11 with 18-trisomy, 2 with 13-trisomy, 2 with 45, XO monomer and 2 with 92, XXXX tetraploid. Chromosome structural abnormalities were found in 21 cases, including 4 with translocation, 3 with insertion, 6 with inversion, 4 with deletion and 4 with derivation. Prenatal ultrasound showed obvious structural abnormalities in 22 cases (41.5%), structural malformation with ultrasonographic soft markers in 18 cases (34.0%), and separate ultrasonographic soft markers in 8 cases (15.1%).

CONCLUSIONPrenatal ultrasound fetal abnormalities and chromosome abnormalities are closely related. Prenatal ultrasound of fetal chromosomal abnormalities usually presents with a variety of significant structural abnormalities. A greater number of malformations is associated with a greater risk of chromosomal abnormalities and increased occurrence of ultrasonographic soft markers.
