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.

0 05) for inducible VT; Utility of QTD≥70ms combined with positive VLP had a more satisfied outcome than using either of these abnormalities in predicting inducible VT. Conclusion QTD is an easily measurable electrocardiographic index for predicting coronary heart disease.

Objective:To assess the prevalence of depressive symptoms in type 2 diabetic patients with hypertension.Methods:A systematic electronic search was conducted in CNKI,Wanfang database,SinoMed,Pubmed and Embase.Literatures that reported the depressive symptoms status of type 2 diabetic patients with hypertension were included.All patients were divided into case group and control group,according to with or without hypertension.Meta-analysis was performed with Statal2.0 software after data extraction and the quality of studies assessment.Results:A total of 11 articles involving 8031 type 2 diabetic patients were included in the meta-analysis,including 4711 patients in case group and 3320 patients in control group.The pooled prevalence of depressive symptoms in case group was 43.5％ (95％ CI:26.1％-60.8％).The pooled prevalence of depressive symptoms in control group was 34.0％ (95％ CI:19.6％-48.5％).The pooled odds ratio was 1.32 (95％ CI:1.05-1.67,P ＜0.05).Conclusion:Hypertension increases the risk of developing depressive symptoms in type 2 diabetic patients.Therefore,medical staff should pay more attention to the mental health of this population.

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.

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 study the potential mechanism of recovery from dysphagia after surface electrical stimulation. Methods 3 cases recovery from dysphagia caused by lower brainstem infarction after surface electrical stimulation of lower mandible and trigeminal nerves were analyzed. Results After 3～16 weeks surface electrical stimulation, the swallow assessment scores reached from 0 to 6 in all the 3 patients. Conclusion Surface electrical stimulation can facilitate the recovery of swallow function, which may be involved with the sensory input, especially the integration of nucleus of the solitary tract (NTS).

Weanlimg male rats fed on synthetic diet containing 1% succinylsulfa-thiazole and devoid of vitamin B12 and folic acid for 3-5 weeks, developed syndromes of the vitamins deficiency, i.e. poor food consumption, low growth rate, decrease in white cell count and marked increase in formimi-noglutamic acid excretion.Nevertheless, the others had an intake of vitamin B12 (0.02 ?g/day/-rat) and folic acid (0.5?g/day/rat) for a 36-day period, also showed signs of vitamins deficiency. But when given a daily dose of 0.1 ?g of vitamin B12 and 2.5 ug of folic acid, the rats had a good appetite and grew well, and excreted more formiminoglutamic acid than normal rats, when they were given a loading dose (0.05 g/rat) of histidine. Under the similar feed- ing condition, rat ingesting a daily dose of 0.3 ug of vitamin B12 and 7.5ug of folic acid, showed no obvious syndomes of the vitamins deficiency.After the rats were fed on the same diet and given with vitamin B12 (0.02 ug/day/rat) and folic acid (0.5ug/day/rat) for a 36-day period, the animals developed increased radiosensitivity. After total-body irradiation (700 rad), the food consumption, growth rate and survival rate in this group were lower than those in other groups ingesting individually 0.1 ug of vitamin B12 and 2.5 ug of folic acid or 0.3ug of vitamin B12 and 7.5 ug of folic acid daily.After irradiation, in the group of 0.02 ug of vitamin B12 and 0.5 ug of folic acid or 0.1 ug of vitamin B12 and 2.5 ug of folic acid in daily in-gestion there was a considerable increase in formiminoglutamic acid with a loading test of histidine(0.05 g/rat) than before. The results showed that the radiation intensified vitamins deficiency in rats.

The dynamic variation of folate content in the whole blood from ?-irra-diated rats have been observed. The level of folate, which did not alter significantly 24 hours after whole-body exposure of 800 rads, decreased dramatically to about 50 percent at the 5th day and to about 67 percent at the 10th day. After irradiation the haemoglobin concentration in rats also decreased, but there was no coincidence between the dynamic variation of folate level and haemoglobin concentration. It is probable that ionizing radiation induces the folic acid malnutrition of rats.

Sixty male rats divided into the control and the gelatin group were fed with 20% protein synthetic diet. The diet for the former group contained 24% casein, whereas for the latter 11% gelatin and 12% casein. , Having been fed for some days, all rats were irradiated with 875 rad (LD85-90). The main results were summarized as follows;1. The gelatin group had higher survival rate than the control group. 2. The body weight of gelatin group was less declined than that of control group and then much restored than the latter. 3. The survival time of dying rats within 14 days following the exposure to 875 rad in gelatin group was more longer than that in control group. 4. The gelatin group had less biological lesions than the control group.It was suggested that the gelatin diet had distinctly prophylactic-therapeutic action on acute radiation damage and its mechanism was probably related to the prevention from disturbance of collagen metabolism.
