The protective effect of TGPs on acute liver damage induced by carbon tetrachloride ( CCl4 ) was investigated in mice . TGPs ( 40 or 80mg/kg?d ? 3d, ip ) reduced the elevation of plasma or serume gl- utamic pyruvic transaminase ( GPT ) and plasma lactate dehydroge-nase ( LDH ) in CCl4-intoxicated mice, but if had no significant influence on the elevation of plasma glutamic oxalacetic transaminase ( GOT).TGPs (40mg/kg?d ? 3d, ip ) showed a protective effect on the histopathologic changes of liver injury induced by CCl4. The results suggest that TGPs may a protect against hepatic damage.

Objective To study clinical characteristics and CT features of cerebellar hemorrhage in the elderly patients in order to make early diagnosis and treatment. Methods The clinical characteristics, CT scan, sites and causes of hemorrhage, as well as the treatment and the prognosis of 32 elderly patients with cerebellar hemorrhage were analysed. Results The main clinical symptoms were vomiting, vertigo and headache and were observed in 32(100.0%), 26(81.2%) and 18(56.2%) cases, respectively. High motality rate was observed in hemorrhage volume≥25 ml, patients aged over 70 years and accomanied with cerebral hernia and multi-organ failure. Conclusions The clinical manifestations of cerebellar hemorrhage were not typical in the elderly. Cerebral hernia and multiple organ failure were the main causes of death. Hypertension and artherosclerosis were the main etiologies of cerebellar hemorrhage. The early diagnosis is necessary for the treatment of cerebellar hemorrhage. The prognosis was related to the quantity and site of hemorrhage.

Objective To evaluate the application of high-performance liquid chromatography (HPLC) in diagnosis and screening of thalassemia. Methods Automated HPLC was used to measure HbF and HbA2 in 100 genetically diagnosed thalas-semic patients and 35 normal children. The results were compared with those from traditional tests including alkali denaturation test and cellulose acetate electrophoresis. The diagnose accordance rates, sensitivity and specificity were compared. Results Seventy-fourβthalassemia, 64 were heterozygous with single mutations and 10 were compound heterozygous with double muta-tions. Twenty-sixαthalassemia, 25 were compound mutations and one was heterozygous with single mutation. The HbF percent-age from HPLC was higher than that from alkali denaturation tests in either thalassemia or normal children (P<0.01). HbF level from HPLC inα-thalassemia was signiifcantly different from that in the normal children (P=0.011). The percentage of HbA2 from HPLC was higher than that from cellulose acetate electrophoresis (P=0.010). HbA2 in the single heterozygousβ-thalassemia were twice higher than that in the double heterozygous mutatedβ-thalassemia (P<0.01). The combination of HbF-HbA2 (≥4.0%) from HPLC with MCV (<80 lf) and MCH (<27 pg) had high accordance rates (99.3%), sensitivity (99.0%) and speciifcity (100.0%) in diagnosis of thalassemia. Conclusions When the results of HPLC are combined with MCV and MCH, it can be applied to the diagnosis of thalassemia with high speciifcity, high sensitivity and has high diagnostic accordance rate with genetic results. HPLC can be an ideal approach to screenβthalassemia.

Objective To investigate the effect of integrated swallowing function rehabilitation training on nasal feeding patients with pseudobulbar palsy or bulbar palsy after acute ischemic stroke. Methods A total of 54 patients met the diagnosis criteria were enrolled prospectively. They were divided into either an integrated group (n=31)or a control group (n=23)using a random number table method. The patients of the control group received routine treatment of stroke,including brain protection therapy,improvement of cerebral circulation,dehydration,regulating blood pressure,and symptomatic treatment,etc;in addition to conventional treatment,those of the integrated group also received integrated swallowing function rehabilitation training,including neuromuscular electrical stimulation plus swallowing reflex facilitation technique,and oral facial glossopharyngeal function training,etc. The oral intake function in patients of the integration and pseudobulbar palsy or bulbar palsy (according to MRI and signs)was compared between the two groups. The evaluation index was the Functional Oral Intake Scale (FOIS)score. Results (1)The FOIS score (median 4)of the integrated group was higher than that of the control group (median 2). There was significant difference between the two groups (P<0. 01). There was also significant difference before and after comparison between the two groups. (2)The FOIS score of pseudobulbar palsy in the integrated group was higher than that of the control group (median scores 4 and 2 ). There was significant difference (P<0.01);There was no significant difference in the FOIS scores of bulbar palsy between the two groups,but the FOIS score of the integrated group was higher than that of the control group (median scores 4 and 3). (3)The median differences between the integrated group and the control group were 2 and 1 respectively. The increased amplitude of FOIS of the integrated group was higher than that of the control group. There was significant difference (P<0. 01). Conclusion The integrated swallowing function rehabilitation training can improve the oral intake function,significantly reduce irritating cough,increase the capacity of oral intake,and increase the types of food. The effect of the improvement of pseudobulbar palsy is more significant in the integrated group.

BACKGROUND: Through exercise and/or hypoxia to increase the body's stress level and timing of hypoxia, so as to improve the body's adaptation level to exercise and/or hypoxia. However, little was known concerning the effects of acute exercise and/or hypoxia on vascular endothelial cell growth factor (VEGF) expression in skeletal muscles.OBJECTIVE: To study the effects of acute exercise and/or hypoxia on VEGF expression in rats' gastrocnemius muscles. DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed at the Clinical Laboratory, People's Hospital of Jiangsu Province, between September 2005 and September 2006.MATERIALS: Totally 108 health male SD rats were randomly divided into 6 groups, namely, normoxia quiet, normoxia high intensity, normoxia moderate intensity, hypoxia quiet, living high-training low high intensity and living high-training low high intensity moderated intensity groups, with 12 animals in each group.METHODS: In acute normoxia exercise models, rats were performed adaptive activity at 48 hours prior to experiment. The high intensity exercise was comprised of 50 m/minx1.5 min training with 2 minutes rest. The moderate intensity exercise was 30 m/min×30 min. Hypoxia environment was produced by using low oxygen instrument to simulate hypoxia training, with hypoxia for 3 days, 22 h/d, 12.8% altitude, with 22 ℃ temperature and 55% humidity. In acute training low-living high models, rats were placed in above hypoxia environment after high intensity Or moderate intensity exercise. Four rats were sacrificed at hours 0, 2 and 4 after training, and the gastrocnemius muscles were obtained.MAIN OUTCOME MEASURES: The expression of VEGF in rats' gastrocnemius muscles was detected by using western-blot.RESULTS: Hypoxia and acute normoxia exercise enhanced the expression of VEGF, hypoxia after exercise weakened exercise-induced VEGF expression, and the exercise with long time and common intensity induced the higher level VEGF expression. The expression of VEGF was the most at the time points of instantaneousness and 2 hour after exercise, the sorting of the recovery speed of VEGF changes from fast to slow was: hypoxia or training low-living high and normoxic exercise. CONCLUSION: The expressions of VEGF in rats' skeletal muscles induced by acute exercise and/or hypoxia belong to the effect of immediate-early, with existing intensity-threshold, which recovery speed is inversely proportional to the expression amplitude;"training low-living high" may be able to enhance the adaptation of skeletal muscles to sports.

Objective To investigate the influence of remote care management on the diet compliance and disease recurrence of patients with pancreatitis. Methods Seventy-four simple pancreatitis patients in our hospital from January 2013 to March 2014 were involved and numbered according to the administration order and divided into the observation group and the control group according to the random number table with 37 cases in each group. The two groups accepted conventional health education during hospitalization time. The control group was given intensive classes after discharge, while the observation group received remote care management. Twelve months later, the rate of disease recurrence and diet compliance of the two groups were observed and compared. Results After the management, the observation group was superior to the control group in diet compliance. The rate of disease recurrence was significantly lower in the observation group than that of the control group (all P<0.05). Conclusion The remote care management can effectively improve the diet compliance of pancreatic patients, lower the recurrence rate, and have positive effect on prognosis.
