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 explore the changes of the plasma motilin(MTL)and serum gastrin(GAS)levels and their relationship with course of disease,the severity,the complication of digestive system in neonates with intracranial haemorrhage(ICH).Methods The objects were 26 cases of term newborns with ICH,the healthy control group contained 30 cases of healthy term newborns.Plasma motilin and serum gastrin concentration were measured by radioimmmunoassay in 26 cases of newborns with ICH in the 2 d,3-5 d,7-10 d,and 12-15 d after birth,and compared with the healthy control group.Results Compared with healthy control group,the blood GAS and MTL levels of neonatal ICH group increased dramatically(Pa

ObjectiveTo investigate and compare the behavioral changes, neuron loss of hippocampus and mossy fiber sprouting between pilocarpine-induced status epilepticus (SE) model and pentylenetetrazole (PTZ) kindling model in rats.MethodsAfter two different epilepsy models were made, Vedio was adopted to observe the behavioral changes. Nissl staining and Neo-timms' staining were separately used to observe and compare the neuron loss of hippocampus and mossy fiber sprouting in the dentate gyrus (DG) at different time points during epileptogenisis.ResultsNo recurrent spontaneous seizure, no neuron loss and no mossy fiber sprouting were found in PTZ kindling model; whereas obvious neuron loss was found in CA1, CA3 of hippocampus and hilus of DG, and mossy fiber sprouting were found in pilocarpine model in parallel with recurrent spontaneous seizures. ConclusionPTZ kindling model resembles absence epilepsy in human, while pilocarpine-induced status epilepticus model resembles chronic temporal epilepsy in human. Neuron loss and mossy fiber sprouting may play an important role in epileptogenisis. Pilocarpine-induced epilepsy model can be regarded as an ideal chronic temporal epilepsy model.

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

OBJECTIVETo explore the effect of combination therapy of tetramethylpyrazine (TMP) with methotrexate (MTX) on collagen induced arthritis (CIA) rats.

METHODSTotally 55 male SD rats were stratified by body weight. Nine of them were randomly recruited as the normal control group. The rest 46 were immunized with type II bovine collagen (C II) for establishing rheumatoid arthritis (RA) model. Forty successfully modeled rats were randomly divided into 4 groups according to swollen toe degree, i.e., the CIA group, the TMP group, the MTX group, and the TMP plus MTX group, 10 in each group. Rats in the MTX group were administered with MTX (1. 2 mg/kg) , once per week for 4 continuous weeks. Those in the TMP group were administered with 40 mg/kg TMP, once per day for 10 continuous days, and then discontinued for 7 successive days, and continued for another 10 successive days. Rats in the TMP plus MTX group were administered with a mixture of equal dose MTX and TMP, and when MTX was discontinue, TMP was administered according to the way in the TMP group. Equal volume of saline solution was given to rats in the normal control group and the CIA group. Clinical parameters including ankle width (mediolateral diameter) and hindpaw swelling were measured at day 0, 4, 11, 18, and 26 after treatment. Rats were sacrificed 28 days after treatment, their knee joints and ankle joints were collected for pathological analyses. Serum levels of IL-1β, IL-6, and IL-17A were detected by ELISA. Changes of fibrinogen (FIB) and platelet aggregation rate (PAg) were detected.

RESULTSCompared with the normal control group, the ankle width and hindpaw swelling increased significantly (P < 0.01), contents of FIB and PAg increased obviously (P < 0.05, P < 0.01), serum levels of IL-1β, IL-6, and IL-17 increased remarkably (P <0. 01) in the CIA group. Obvious cell proliferation, inflammatory cell infiltration, hyperemia and edema of synovial tissues could be seen. Pannus formed and immerged in cartilages, resulting in necrosis. Compared with the model group, changes of ankle width and hindpaw swelling were all alleviated in each medicated group (P <0. 05, P <0. 01). Of them, the effect was superior in the MTX group to that of the TMP group and the MTX plus TMP group (P < 0.05, P < 0.01). Contents of FIB, serum levels of IL-1β and IL-6 decreased significantly in the MTX group (P < 0.05). Contents of FIB, serum levels of IL-1β and IL-6 decreased significantly in the TMP group and the MTX plus TMP group (P < 0.05). Besides, serum levels of FIB and IL-6 were obviously lower in the MTX plus TMP group than in the TMP group and the MTX group (P < 0.01). Levels of PAg and IL-17A were more significantly lowered in the TMP group than in the MTX plus TMP group and the MTX group. Pathological changes could be alleviated in each medicated group, with the optimal effect obtained in the MTX plus TMP group.

CONCLUSIONCombination of TMP with MTX could significantly ameliorate inflammatory reactions and FIB contents of CIA rats.

OBJECTIVETo evaluate the change of blood pressure, ECG and nitric oxide (NO) in rat heat stroke and effects of aminoguanidine (AG) against heatstroke.

METHODSThe male SD rats were randomly assigned into 1 of the following 2 groups: control group or AG group. The rats of control group (n = 10) and AG group (n = 10) were exposed to high ambient temperature (41 degrees C, relative humidity 65%) to induce heatstroke, arterial blood pressures, colonic temperature (T(co)), electrocardiograph (ECG) were monitored. The other rats of both groups (both n = 10) were exposed to high ambient temperature (41 degrees C, relative humidity 65%), and the blood samples were taken at 0, 60 min after the start of heat exposure for determination of the plasma NO concentrations.

RESULTS(1) From 0 min to 50 min after heat exposure, MAPs of two groups were not significantly different, but at about 55 approximately 60 min after the start of heat exposure, MAPs of control group were decreased significantly differently from that of AG group, K value and dicrotic pulse relative height (h(D)/H) were gradually decreased, especially at 40 min after the start of heat exposure, K value of control group decreased significantly comparison with that of AG group; (2) Heart rate (HR) and QT interval of both groups were increased, while PR interval were decreased after the start of heat exposure; (3) T(co) of both groups were increased after the start of heat exposure until T(co) increased to 42 degrees C (the onset of heatstroke), but there was not significantly difference between the two groups; (4) The time of the onset of heatstroke (TOHS) and survival time (ST) of AG group were significantly longer than those of control group; (5) The plasma NO concentrations of the two groups were significantly higher at 60 min than at 0 min after the start of heat exposure, and the plasma NO concentrations of control group were significantly higher than that of AG group at 60 min after the start of heat exposure.

CONCLUSIONiNOS may contribute to heatstroke, and aminoguanidine can provide protective effects on heatstroke as a selective iNOS inhibitor.

OBJECTIVETo investigate possible relationship between expression of surfactant protein B (SP-B) gene product and neonatal respiratory distress syndrome (NRDS) in Han ethnic group.

METHODUnrelated 20 cases with NRDS of Han ethnic group were selected as NRDS group while unrelated 20 diseases cases of Han ethnic group with diseases were selected as control group. The cases in the control group had congenital heart disease or bronchopulmonary dysplasia or persistent pulmonary hypertension. Blood sample was taken from every case. Lung tissues were taken from the patients who died half an hour after death in the two groups. Expression of SP-B in lung tissue was determined with immunohistochemical tecnique. Genetic deficiency variant of SP-B intron IV was screened with polymerase chain reaction (PCR).

RESULTSTwo cases at gestational age 26 weeks and one case at gestational age 34 weeks and two cases at gestational age 42 weeks of NRDS groups had lower level expression of SP-B in lung tissue than those at the same age of NRDS. Expression of SP-B in lung tissue of control group increased with gestational age, but no such phenomenon was found in NRDS group. Further, two cases at gestational age 42 weeks of NRDS group had genetic deficiency variant of SP-B intron IV with gene analysis of five cases who had lower expression of SP-B. Clinical data suggest that patients at 42 weeks of gestational age had severe illness.

CONCLUSIONSDecrease of SP-B expression may participate in occurrence of NRDS, genetic deficiency variant of SP-B intron IV exists in the NRDS cases of Han ethnic group of China.

Objective To explore the biological exposure limit of liver dysfunction induced by arsenic-coal burning, and screen sensitive biornarkers for its' liver dysfunction monitoring. Methods One hundred and eighteen subjects from the exposed area and 50 control from non-pollution area were studied. Their urinary and hair contents of arsenic were tested as exposure biomarkers by Ag-DDC assay. Total bile acid(TBA, detected by enzymatic cycling method), glutathione S-transferase (GSTs, detected by chemical colorimetry) and γ-glutamyl transpeptidase (γ-GT, detected by colorimetry of diazotization reagent) were used as biomarkers indicating liver cell damage. were used as liver fibrosis biomarkers. The benchmark dose (BMD) and the lower confidence limit of benchmark dose(BMDL) of urinary and hair arsenic were calculated. Sensitivity of each biomarker was estimated according to the BMD and BMDL value. Results The geometric mean of urinary and hair arsenic(98.50 mg/kg Cr, 7.42 mg/kg) μg/L) in the exposed group were significantly higher than urinary and hair arsenic (22.98 mg/kg Cr, 1.28 mg/kg) and each biomarker in the control group(4.63 μmol/L, 13.76 U/L,36.45 U/L,54.62 μg/L,74.45 μg/L,54.81 μg/L, P<0.01). Significant dose-effect relationship existed between urinary and hair arsenic contents and each biomarker. BMD and BMDL value of urinary arsenic was 49.53-101.96 mg/kg Cr and 39.02-70.15 mg/kg Cr, respectively. Those of hair arsenic were 3.04-5.02 mg/kg and 2.36-3.25 mg/kg, respectively. According to BMD and BMDL value of urinary and hair arsenic, the sensitivity of biomarkers decreased in the order of GSTs, TBA and Conclusions According to the lowest BMD and BMDL of urinary and hair arsenic, averaged reference value of urinary and hair arsenic in the local normal population, we suggest urinary 35.0 mg/kg Cr and hair 2.5 mg/kg as their biological exposure limits for those with liver dysfunction induced by arsenic-coal burning. GSTs, TBA, γ-GT and HA, Ⅳ. C, PC-Ⅲ can respectively reflect liver cell damage and liver fibrosis caused by arsenic-coal burning in different degrees, among which, GSTs and HA are the most sensitive biomarkers respectively for liver cell damage and liver fibrosis.

[Objective]To explore the effect of body weight support treadmill training (BWSTT) on motor function of lower extremities,walking ability,activities of daily living and quality of life in chronic hemiplegic patients after stroke.[Methods]Fifty-eight stroke patients in sequela stage,admitted to our hospital from May 2009 to June 2011,were randomly divided into BWSTT group (n=30) and control group (n=28).Patients in the control group received conventional rehabilitation training while those in the BWSTT group received both conventional rehabilitation training and BWSTT.Functional Ambulation Category (FAC),Fugl-Meyer Assessment (FMA),Barthel Index (BI) and Short Form-36 (SF-36) were used to assess the effect before treatment and 8 weeks after treatment.[Results] Before treatment,no significant differences in terms of scores with FAC,FMA,BI and SF-36 were noted between the 2 groups (P＞0.05).After treatment,the FAC,FMlA,BI and SF-36 scores were all signficantly improved in both groups (P＜0.05);and the BWSTT group scored significantly better than the control group (P＜0.05).[Conclusion] BWSTT can significantly improve the walking ability,motor function of lower extremities,activities of daily living and the quality of life of stroke patients in sequela stage.

OBJECTIVETo analyze the effectiveness of Chinese medicine and integrated Chinese and Western medicine for influenza A (H1N1) in the fever clinics and its relevant expenditure.

METHODSA prospective survey on the clinical epidemic observation and follow-up was conducted from July 2009 to October 2009 with a self-developed questionnaire whose contents including the clinical data of the confirmed 149 H1N1 cases and their relevant therapeutic expenditure. The patients were assigned to the Chinese medicine group (22 cases treated by Chinese medicine alone) and integrative medicine group (124 cases treated by both Chinese medicine and Western medicine). The data were processed with descriptive analysis, t test and χ (2), and sum-rank test.

RESULTSThe proportion of clinical recovery of Chinese medicine group (81.8%) was higher than that of integrative medicine group (54.8%) with statistical significance (P=0.02). The average fever durations in both groups were 3.5 to 4 days, showing no significant difference (P=0.86). In the comparisons of average cost of Chinese herbs, drugs, therapies, and total cost, those of the Chinese medicine group were lower than those in the integrative group (P=0.01, P=0.00, P=0.00, P=0.00).

CONCLUSIONSThe H1N1 patients in the fever clinic who received Chinese medicine treatment had a higher clinical recovery proportion than those who received integrated Chinese and Western medicine treatment with lower medical cost. However, due to small sample size of the Chinese medicine group in the study, the conclusion needs further confirmation by studies with large sample size.
