Objective To evaluate the effects of TENS on metatarsus plantar flexion and inversion in stroke patients,and to explore its mechanism.Methods Thirty-two stroke patients with gastrocnemius spasticity were randomly divided into a control group (n=16) and a TENS group (n=16).All patients were treated with foot sup- ports,neurodevelopmental and manipulation therapies.In addition,the TENS group received TENS on the anterior tibialis,peroneus longus and brevis muscles.All patients were assessed in terms of their Chinese stroke scale(CSS) and H reflex scores before and after therapy.Results Compared with those in the control group,the H reflex scores in the TENS group were obviously decreased,while H reflex latency was prolonged and H/M was reduced. Gait in the TENS group was evidently improved.Conclusion TENS is an effective therapy to decrease gastrocnemi- us spasticity and to improve the gait of stroke patients.

Objective To explore a better method for treatment atrophic rhinitis.Methods 56 patients with atrophic rhinitis(96 lateral)were treated by nasal submucou pediculated bone-suberiosteal muscle flap extracted from anterior wall of sinus maxillaries.Results All patients were followed 2 to 10 years,total effective rate was 100 %, with 49 cases(87.5 %)showing prominent effect.Conclusion The grafted flap cannot be assimilated,felled off and necrosis,because the flap has rich blood supply.This methods has obvious short-term effective and stable long-term effective.No complications were found.

BACKGROUND: Ulinastatin (UTI) is a urinary trypsin inhibitor extracted and purified from urine of males. This study aimed to explore the effects of UTI on paraquat-induced-oxidative stress in human type II alveolar epithelial cells. METHODS: The human type II alveolar epithelial cel s, A549 cel s, were cultured in vitro. The A549 cel s were treated with different concentrations of paraquat (200, 400, 600, 800, 1000, 1200 μmol/L) and ulinastatin(0, 2000, 4000, 6000, 8000 U/mL) for 24 hours, the cell viability was measured by cell counting kit-8 and the median lethal concentration was selected. In order to establish an in vitro model of paraquat intoxication and to determine the safe dose of ulinastatin, we calculated LD50 using cell counting kit-8 to determine the survival rate of the cells. A549 cells were divided into normal control group, paraquat group and paraquat+ulinastatin group. The levels of malondialdehyde (MDA) and myeloperoxidase (MPO) were detected by biochemistry colorimetry, while the level of reactive oxygen spies (ROS) was detected by DCFH-DA assay. RESULTS: The survival rate of A549 cells treated with different concentrations of paraquat decreased in a concentration-dependent manner. Whereas there was no decrease in the survival rate of cells treated with 0–4000 U/mL ulinastatin. The levels of MDA, MPO, and ROS were significantly higher in the paraquat group than in the normal control group after 24-hour-exposure. And the survival rate of the paraquat+ulinastatin group was higher than that of the paraquat group, but lower than that of the normal control group. The levels of MDA, MPO, and ROS were lower than those of the paraquat group. CONCLUSION: Ulinastatin can alleviate the paraquat-induced A549 cell damage by reducing oxidative stress.

OBJECTIVE To investigate the therapeutic effect and side effect of ibrutinib long-term treatment in systemic lupus erythematosus (SLE) model mice induced by pristane. METHODS Female 6-week old BALB/c mice were ip given pristane 0.5 mL once for SLE induction. Four weeks later, the SLE model mice were divided into three groups based on the body mass and serum level of anti-double-strand DNA (DS-DNA) antibody and treated with 1%methylcellulose (model control group, ig), ibrutinib (30 mg·kg-1, ig) or prednisone (10 mg·kg-1, ig), respectively, once daily for 28 weeks. Every 4 weeks, body mass of each mouse was measured. Autoantibodies against DS-DNA, single-strand DNA (SS-DAN), and histone were tested by ELISA. The incidence of lupus arthritis and clinical score of inflammation and edema were recorded and graded. Biochemical analysis of urea protein, serum urea nitrogen and creatinine was used to evaluate kidney function. Mice were euthanized post 28 weeks of dosing. Inter-leukin-6 (IL-6), interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) were tested by ELISA. The heart, liver, spleen, lung, and kidney were collected and weighed for organ relative mass calculation. Biochemical analysis of serum glutamic-pyruvic transaminase (GPT), glutamic-oxal(o)acetic transaminase (GOT) and alkaline phosphatase (ALP) was used to evaluate liver function. Hind feet were collected for HE staining and pathological scoring to observe renal injury and inflammation. Immunohistochemical staining was used to study IgG immune complexes deposition in kidneys of lupus. RESULTS Compared with normal control group, autoantibodies (anti-DS-DNA, anti-SS-DNA and anti-histone antibodies), renal function indexes (serum creatinine, urea nitrogen and urine protein), and cytokines (IL-6, IFN-γ and TNF-α) levels in model group were significantly increased (P<0.01). The model group mice had obvious clinical symptoms of arthritis (P<0.01), serious inflammation cell invasion (P<0.01), and the mass of kidneys and spleen increased significantly (P<0.01). Compared with model group, after 28 weeks of treatment, ibrutinib decreased the level of anti-DS-DNA, anti-SS-DNA and anti-histone antibodies (P<0.01), decreased the lupus arthritis score (P<0.01) and the morbidity of arthritis, reduced the level of cyto-kines IL-6, IFN-γand TNF-α(P<0.01), reduced the level of serum creatinine, serum urea nitrogen and urine protein (P<0.01), improved pathological symptoms of hind feet such as inflammation, cartilage destruction, bone resorption and pannus (P<0.01), alleviated renal tissue inflammatory cell invasion and the immune-complex precipitation, and reduced the mass of organs (spleen and kidneys, P<0.01) and the level of liver function (GPT and ALP, P<0.01). CONCLUSION Long-term treatment with ibrutinib has therapeutic effect on the model mice of SLE, and has no obvious side effect.

Objective To observe the incidence and clinical characteristics of chronic Keshan disease in recent years, and to provide evidence for diagnosis of the disease. Methods From March to August 2009, 163 patients with chronic Keshan disease were chosen from Shandong, Sichuan, Inner Mongolia and Cansu. Of these patients, 62 cases were from Shandong, 34 cases from Sichuan, 37 cases from Inner Mongolia, and 30 cases from Gansu. All of the subjects underwent detailed natural history of the disease, careful physical examination and electrocardiogram (ECG), X-ray chest radiography and cardiac ultrasound examination. The incidence and clinical features were analyzed. Results Adults accounted for 98.8%(161/163) and children for 1.2%(2/163) in 163 cases of chronic Keshan disease, with an average age of 45.8 years. Slow onset accounted for 62.6%(102/163), other types that evolved into chronic-type accounted for 37.4%(61/163). Low blood pressure( 116.5/72.4 mmHg),often with cardiac function grade Ⅱ accounted for 65.6%(107/163). Common symptoms were: palpitation[86.5%(141/163)], asthma [76.7% (125/163)], fatigue[76.1%(124/163)], precordial discomfort [54.6% (89/163)], dizziness[50.3%(82/163)], edema of lower limbs[44.8%(73/163)], and anorexia[38.0%(62/163)]. Common signs were: low-weak first heart sound[66.9%(109/163)], heart enlargement[64.4%(105/163)], apical pulse dispersion[42.3%(69/163)], arrhythmia[40.5%(66/163)], hepatomegalia[39.3%(64/163)], systolic murmur [25.2%(41/163)], and edema[20.9%(34/163)]. Abnormal ECG detection rate was 93.9%(153/163), with common types followed by ST-T changes[ST-T changes, ST segment changes, Tchange, 36.2%(59/163)], ventricular premature [occasional and frequent ventricular premature, 26.4% (43/163)], complete right bundle branch block [25.8% (42/163)], atrial fibrillation[19.0%(31/163)], and atrioventricular conduction block[8.6%( 14/163)]. X-ray results showed that significant and moderate heart enlargement were common, accounting for 73.4%( 105/143), followed by mild enlargement of 25.2%(36/143). Color doppler ultrasound examination results showed that the atrio-ventricular cavity diameter increased, followed by left ventricular end-systolic diameter increased[81.3%(52/64)], left ventricular end-diastolic diameter increased[65.6%(42/64)], left atrial enlargement[51.6%(33/64)], right atrial enlargement [43.8%(28/64)], and right ventricular enlargement[32.8%(21/64)]. Left ventricular wall and interventricular septum thinning accounted for 15.6%( 10/64) and 7.8%(5/64), respectively. Conclusions In recent years, most cases of chronic Keshan disease occur as natural chronic type, and at older age at onset with low blood pressure.Main clinical features of the disease are cardiac enlargement, inadequate tissue perfusion, and venous stasis performance caused by cardiac decompensation. Correct diagnosis of chronic Keshan disease can be made based on these clinical features.

OBJECTIVETo probe into the relationship between hypertension and hemodynamic score of cerebral vascular accumulative function by though studying the history of hypertension and level of blood pressure.

METHODSThe database of blood pressure and cerebral vascular hemodynamic indexes (CVHI) were from baseline data and measurement in a cohort. 18,512 participants who met the included criteria were enlisted in the study. The function scores were estimated using uniform methods according to CVHI. Participants were grouped by age, years of having hypertension and level of blood pressure. Differences of the function score between different groups were compared.

RESULTSThe function score in hypertension group was significantly lower than that of normal tension group, which decreased by 13.3 points. Within 5 years of hypertension history, the function score decreased as course of hypertension prolonged. The same trend was found between the score and level of both systolic and diastolic blood pressure. When systolic blood pressure elevated to 140 mmHg or diastolic blood pressure elevated to 95 mmHg, the function score was below 75 points.

CONCLUSIONThere were significant relationship between decrease of the function scores and medical history, course of hypertension as well as level of blood pressure.

Objective To investigate the relationship between drinking-water type of endemic arsenicosis and adult carotid artery atherosclerosis. Methods In 2009, 285 participants aged over 40 from drinking-water type of endemic arsenism areas and 293 residents aged over 40 from control areas were investigated in Yingxian county,Shanxi province. Portable-type B mode color ultrasound was used to examine the carotid artery of all participants.The carotid atherosclerosis were diagnosed and graded through the ultrasonograms. Content of water arsenic and hair arsenic of 10 people randomly selected in every villages were detected. Results A total of 5 villages with drinkingwater type of endemic arsenicosis as observation group and 5 villages without drinking-water type of endemic arsenicosis as control group were investigated. The prevalence rates of adult carotid atherosclerosis within observation group were 35.09%(20/57), 55.74%(34/61), 38.46%(20/52), 36.51%(23/63) and 46.15%(24/52), respectively,and standardized prevalence rates were 32.5%, 33.8%, 34.9%, 46.2% and 47.3%, respectively and the prevalence rates of adult carotid atherosclerosis within control group were 18.18%(10/55), 30.77%(16/52), 20.00%(10/50),18.67% (14/75) and 21.31% ( 13/61 ), respectively; the standardize prevalence rates were 22.4%, 17.7%, 10.7%,24.6%, 18.9%, respectively. The standardize prevalence rates were higher in observation group [39.50%(113/285) ]than that in control group[39.50%(113/285), T = 26, P ＜ 0.01 ]. The severity of adult carotid atherosclerosis (composition of 4 - 7 scores ) was compared between observation group [ 17.70%(20/113 )] and control group [ 14.06% (9/64) ], and the difference was insignificant(x2 = 0.26, P ＞ 0.05). Conclusions The prevalence rate of carotid atherosclerosis in drinking-water type of endemic arsenicosis areas is higher than that of the control areas.The study provides evidence that arsenic poisoning can cause atherosclerosis.

OBJECTIVETo present data from a baseline investigation on stroke-related cohort population in rural area of Shanghai.

METHODSA cross-sectional study was carried out in a cluster sampling population aged 40 years and over. General information and data on common risk factors in the population were gathered and cerebral vascular hemodynamic indexes were checked. Hemodynamic score was estimated according to single indexes by unified methods. 5335 persons who had met the inclusion criteria were enlisted in the study. Exposure level of risk factors, prevalence of stroke, and hemodynamic indexes were analyzed and distributional characteristics were described.

RESULTSExposure rate of hypertension, heart disease, diabetes, family history of hypertension, overweight or obesity in males were 31.74%, 6.09%, 1.16%, 3.22%, 17.64%, 29.68% and were 32.76%, 9.22%, 1.55%, 3.84%, 19.22%, 29.44% in female respectively. Standard prevalence of stroke was 1167.3/100000, which in male was significantly higher than that in female (P < 0.05). The change of cerebral vascular hemodynamic indexes was significantly associated with age. Hemodynamic score in 21.3% of the subjects was below 75 points.

CONCLUSIONSAmong population of 40 years old and over in rural areas, hypertension was the principal risk factor regarding the rate of stroke. Prevalence of stroke in males was significantly higher than that in females. Abnormal rate of hemodynamic score was about 20% in this population.
