Active constituents in Danshen and Compouud Danshen injections were determined by UV spectrometry and TLC scanning. Results showed that the total amount of catechol like constitucnts in injections obtaiued from thc market varies differeutly. It was proved that all the injectious containcd a large amount of tannius can lead to degeneration of red blood cells and agglutination of plasma protein and cause clinical toxic actions.

Objective To evaluate the physical activity status of the advanced aged adults and determine the influence of long-term physical activities on the physical function and health of the advanced aged adults. Methods A survey was carried out from March, 2004 to September, 2004, among those advanced aged intellectuals or cadres taken care chronically by the Patient Clinic for Senior Cadre in PUMC Hospital. Physical activity was assessed using the modified leisure-time physical activity questionnaire. Results There were 259 participants, aged from 80 to 94 (83.92?3.41)years. 85.3%(221/259 cases)took physical activities almost every day for more than eleven years, and 21.7% of them (48/221 case)even stuck to it from their youth. Among these 221 participants, 34.4% took≥ 60 min per day of physical activities,and 51.0% ≥30 min per day. The group that took ≥ 60 min per day held a lower proportion than the group that took ≥ 30 min per day to suffer from agrypnia, debilitation, somasthenia and anorexy (by 20.3%, 24.0%, 21.7% and 13.1%,respectively(P

Objective: To study the pharmacokinetics of f1omoxef(Fmox) in 8 hea1thy volunteers after infusion of 1 gFmox injection. Methods: Fmox concentrations in plasma and urine were measured by an improved HPLC method. Results:The results showed that peak plasma level (cmax), terminal phase plasma elimination half-life (t1/2?), volume of distribution(Vc ), clearance (CI3)and area under plama concentration-time curve (AUC)were (56.15?13.16) ?g/ml, (1.29?0.32) h,(13. 11?12. 06) L, (16.02?1.88) L/h and (64.86?4.93)?g? h/ml respectively. Conclusion: Drug concentrations-time pro-file of Fmox conforms to a two-compartment open phartnacokinetic model. Fmox is mainly excreted through kidney in un-changed form. The cumulative urinary excretive rate of Fmox is (79. 39l4. 01) % 8 h after administration.

Objective:To assess incidence of malnutrition and malnutrition risk of six department patients.Methods:The information of 1 200 patients were collected,200 in each of 6 departments in our hospital.Nutrition status was assessed according to Nutrition Risk Screening(NRS)published by ESPEN in 2001.Results:The incidence of malnutrition and malnutrition risk varied from 7.5% to 59% and 36% to 72% respectively in different department.Conclusion:The incidence of malnutrition is closely related to the kind and severity of the disease.It is nessissary to assess the nutrition status of high risk patients in time.NRS can be used simply and fastly in most inhospital patients.

BACKGROUND: The minimal latency and conduction velocity of F-wave have been widely used for the detection of varied neurological disorders,whereas the significance and the diagnostic value for the other parameters of F wave are seldom reported. How sensitive are these parameters in the earlier evaluation of diabetic peripheral neuropathy (DPN) ?OBJECTIVE: To investigate the evaluating value of F-wave parameters for the earlier DPN, providing references for earlier clinical rehabilitative intervention.DESIGN: Case-control study with type 2 diabetic patients and health people as subjects.SETTING: The wards and outpatients in the Departments of Neurology and Endocrinology, Renmin Hospital of Wuhan University.PARTICIPANTS: Between January 1999 and December 2000, there were totally 106 patients with type 2 diabetic mellitus(DM) at the wards and outpatients in the department of neurology and endocrinology in Renmin Hospital of Wuhan University, including 64 males and 42 females, with the average age of (55 ± 13) years and the average DM course of (10.2 ± 4. 8)years. Meanwhile, 75 healthy volunteers were enrolled in the control group,including 45 males and 30 females, with the mean age of(54 ± 12) years.Two groups were matched in age and leg length( P ＞ 0. 05).INTERVENTIONS: Using Nicolet Viking-Ⅳ, F wave and M-wave parameters of tibial nerve stimulation were analyzed.MAIN OUTCOME MEASURES: The minimum latency (Fmin), duration (Fdur), amplitude(Famp) and area(Farca) of F wave; and the amplitude (Mamp)and aera(Marea) of M-wave.neuropathy( n = 30), there were 8 cases(the abnormal rate being 27% ) with increased Fdur, 4(13% ) with prolonged Fmin and 2(7% ) with increased F/Mamp and F/Marea increased significantly in the patients with DPN( n = 76).mality rate of Fdur was significantly higher (96% vs 21%, P ＜0.01), the abnormality rate of Fmin was significantly lower(51% vs 76%, P ＜ 0.05 ) and there were no significant difference of other parameters( P ＞ 0.05) in the patients with mild DPN subgroup ( n = 47).diagnostic parameter for earlier DPN, and therefore detect the sub-clinical DPN, and the proximal may be earlier involved than the distal.

Objectives To investigate the inlfuence of polymorphisms of SLC19A1 80G>A, MDR1 exon26C>T and MDR1 exon21G>T/A on curative effect and adverse reaction of high-dose methotrexate in patients with acute lymphoblastic leukemia. Methods MALDI-TOF-MS technique was used to detect the polymorphisms of SLC19A1 80G>A, MDR1 exon 26C>T and MDR1 exon21G>T/A in 108 patients with acute lymphoblastic leukemia (ALL). The relationship of genetic polymorphism, survival rate and toxicity was analyzed. Results The 36-month event-free survival was not related to any polymorphisms of MDR1 and SLC19A1. Patients with mutant types of MDR1 exon26C>T and MDR1 exon21G>T/A showed a much higher MTX plasma levels at 24 hours and higher incidence of hepatic injury (P<0.05). Conclusions The genetic polymorphism of MDR1 exon26>T, MDR1 exon21G>T/A has a large inlfuence on hepatic toxicity and plasma concentra-tions of MTX.

Objective To retrospectively study the biodistribution of 68Ga-DOTA-TATE as a SSTR imaging agent in human subjects.Methods A total of 106 patients with suspected disease were enrolled in this study.All patients were histologically proven for having either a single tumor ＜2 cm or without evidence of tumor during follow-up.Patients underwent PET/CT whole-body scan 17-100 min after intravenous injection of 55.2-220.0 MBq 68Ga-DOTA-TATE.ROI was drawn for measuring SUV of tracer-avid pathologies.One-way analysis of variance and two-sample t test were used for statistical analysis.Results High 68Ga-DOTA-TATE avidity was found in pituitary,with SUVmax of 4.00± 1.21.Tracer was excreted mainly through urinary system resulting in highest uptake in the urinary tracts.The SUVmax of kidney cortex was 19.01 ± 5.45.Mediastinal blood pool and liver SUVmax were 0.93±0.33 and 7.69±2.26,respectively.Mild uptake of 68Ga-DOTA-TATE was found in the brain,cerebellum,lung and muscle,all lower than that of mediastinal blood pool.Moderate accumulation of 68 Ga-DOTA-TATE (close to or slightly higher than liver) was found in adrenal gland and spleen,with SUVmax 7.61 ± 3.42 and 8.63± 2.31,respectively.Other organs (pituitary,salivary gland,thyroid,pancreas,small intestine,colon,uterus,prostate and bone) showed tracer uptake in the range between those of mediastinal blood pool and liver.68Ga-DOTA-TATE distribution in pancreas was not uniform.Nine patients had focal accumulation in the uncinate process of pancreas with highest SUVm~ up to 8.48.However,the SUVmax and SUV in the rest of pancreas (head,neck,body and tail) showed insignificant difference (F values:0.703,0.563,both P＞0.05).68Ga-DOTA-TATE uptake in each organ reached equilibrium quickly after injection but with slight increase over time.The changes in SUV,however,showed insignificant difference among organs,including different parts of pancreas (t values:from -0.09 to 1.75,from-1.70 to-0.42,respectively,all P＞0.05).Conclusions The biodistribution of 68Ga-DOTA-TATE reaches equilibrium shortly after intravenous administration and is stably maintained.The biodistribution activities are organ-specific,and characteristic to that of SSTR concentration.

Objective:To investigate the influence of the teaching model based on the synergy of medical education on the objective structured clinical examination (OSCE) scores and critical thinking ability of interns in emergency department.Methods:A total of 84 students who studied as interns in Emergency Department of our hospital from January 2020 to 2021 were selected as research subjects, and they were divided into observation group and control group using a random number table, with 42 students in each group. The students in the control group were taught using traditional methods, while those in the observation group were taught based on the synergy of medical education. Both groups received an OSCE examination, and the two groups were compared in terms of OSCE score, critical thinking ability, and evaluation of teaching. SPSS 22.0 was used to perform the t-test and the chi-square test. Results:Compared with the control group, the observation group had significantly higher scores of theoretical assessment, disease assessment, first aid measures, special skills, use of medical instruments, communication skills with SP, and medical record writing and a significantly higher total score of OSCE assessment ( P<0.05). After teaching, both groups had a significant increase in the score of critical thinking ability, and the observation group had a significantly higher score than the control group [(306.38±25.76) vs. (280.39±20.17)]. The observation group had a significantly higher degree of satisfaction with teaching than the control group ( P<0.05). Conclusion:The teaching model based on the synergy of medical education can improve the OSCE score of interns in emergency department and cultivate their critical thinking ability, and there is a relatively high degree of satisfaction with this teaching model.

Objective: To analyze the teaching environment of primary, middle and high schools in Suzhou, and to explore the relevance of students’ myopia with teaching environment, as well as the key problems in teaching environment. Methods: 1 253 classrooms in 204 schools rom 10 districts and counties in Suzhou were selected by proportionate stratified sampling. The qualified rate of each indices was described and the teaching environment by county, learning stage were compared by using chi-squared test. The Spearman test is used to explore correlations between myopia with monitoring indicators. Results: The qualified rate of the distance from lamp to table was the highest (98.56%), while matching rate of student desk and chair was the lowest(0.96%). Minimum lamp table spacing, blackboard average illumination, reflectance from blackboard wall, classroom per capita area, classroom microclimate differed significantly in urban and rural (P<0.05); daylighting coefficient, reflectance from walls, average illumination of desktop and blackboard, classroom per capita area, and microclimate indicator were statistically different by learning stages(r=0.42,P<0.05). Prevalence of myopia correlated with the index of lighting. Conclusion Qualified desks and matched chairs, as well as the daylighting design in classroom should receive more attention in Suzhou. The findings lend support to identification of key health priorities and formulation of the localized health practice for health administrations.
