BACKGROUND:After cerebral tissue ischemia and anoxia in young rats,the cerebral edema gets serious, and the levels of nitric oxide (NO) and malondialdehyde (MDA) decrease. Radix Astagali seu Hedysari has the pharmacological effects of enhancing immunity, anti-anoxia and improving myocardial ischemic reinfusion injury.OBJECTIVE: To investigate the influences of Radix Astagali seu Hedysari (huangqi) on contents of NO and MDA in brain tissue of young rats with cerebral injury after cerebral ischemia and anoxia.DESIGN:A randomized and controlled trial.SETTING: Department of Pediatrics, Second Hospital, Hebei Medical University; Department of Internal Medicine, Institute of Traditional Chinese Medicine, Hebei Medical University; Department of Pathophysiology, Hebei Medical UniversityMATERIALS:The experiment was conducted from January to April 2004at Department of Pathophysiology, Hebei Medical University. Total 40 SD rats, 7-day old, were at random divided as normal control group, model group, humgqi low-dose group and huangqi high-dose group, with 10 rats in each group. Huangqi injection (The content in 10 mL injection is consistent with 20 g raw drug) was provided by Institute of Traditional Chinese Medicine of Hebei Medical University (produced in Chengdu Di'ou Jiuhong Pharmaceutical Factory, Batch No. 0005028).METHODS:Except rats in normal group, those in the rest groups, under conscious and local anesthesia, were all given common carotid artery ligation, establishing cerebral injury model due to ischemia and anoxia. Rats in normal group were intraperitoneally injected 0.1 mL normal saline; rats in model group were intraperitoneally injected 9 g/L normal saline, 0.1 mL each day; rats in huangqi low-dose group and huangqi high-dose group were respectively given 0.1mL, 0.5 mL huangqi injection, once a day, intraperitoneally. Cerebral blood flow was detected immediately, 2 and 4days after injection. Then the rats were decapitated for collecting the brains to measure the water content in brain, the contents of NO and MDA.MAIN OUTCOME MEASURES: [1] Water contents in brains of rats in every group. [2] Cerebral blood flow, and the contents of NO and MDA.RESULTS:Totally 40 rats were involved in the trial and all entered in the final result analysis. [1] The water content in brain of each group: Compared with normal group, the content in model group was increased immediately after model establishment [(87.316±0.275)%, (88.259±0.297)% ,P ＜ 0.05 ],and did not return to the normal level at the second day [(86.973±0.265)%,(88.173±0.445)%,P ＜ 0.05]; compared with model group, the content in huangqi high-dose group was obviously decreased at second day[(88.173±0.445)%, (86.542±0.141)% ,P ＜ 0.05]. [2] Measurement of cerebral blood flow: compared with control group, the blood flow in model group was obviously decreased immediately after model establishment[(231.88±13.33), (139.54±10.58)mV,P＜ 0.05], and did not return to normal level till the 4th day [(234.57±14.38), (145.38±13.33)mV,P ＜ 0.05];compared with model group, the blood flow in huangqi low-dose group and huangqi high-dose group, at day 4, was obviously increased [(145.38±13.33),(288.45±12.89), (313.82±21.74)mV,P ＜ 0.01]. [3] The contents of NO and MDA: The contents in model group, immediately after model establishment, were obviously higher than those in normal control group [(26.55±5.23 ), ( 19.67±7.17 )μmol/L,P ＜ 0.05; (7.88±2.55), (4.22±0.12) μmol/L, P＜ 0.01], and at day 4, were significantly higher than those in normal control group [(48.65±17.06), (18.65±2.12)μmol/L,P ＜ 0.01; (5.29±0.68),(4.06±0.39)μmol/L,P ＜ 0.05]; compared with model group, the contents in huangqi low-dose group and huangqi high-dose group were obviously decreased at day 4 [(48.65±17.06), (23.77±12.79), (24.67±11.54)μ mol/L,P＜ 0.01; (5.29±0.68), (4.51±2.30), (3.68±0.39)μmol/L,P ＜ 0.01].CONCLUSION:Huangqi could obviously reduce cerebral edema from ischemia and anoxia, increase cerebral blood flow. It could decrease the contents of NO and MDA that is metabolite of free radical injury, thus playing its role to inhibit lipid peroxidation injury.

BACKGROUND: Cholinergic system projected in brain and hippocampal structure is relevant with learning and memory. Piracetam acts on protecting and repairing cerebral neural cell, resisting cerebral functional injury due to physical and chemical factors and improving learning-memory capacity.OBJECTIVE: Chronic epilepsy in childhood animal and learning-memory complex animal model were self-prepared to observe the changes in content of acetylcholine and activity of cholinacetyltranslase in cerebral hippocampus and the intervention of piracetam.DESIGN: Randomized control experiment and non-blind evaluation were designed.SETTING: Department of Pediatrics of Second Hospital of Hebei Medical University and Institute of Traditional Chinese Medicine of Hebei Medical UniversityMATERIALS: The experiment was performed in Hebei Medical University and College of Life Sciences of Hebei Normal University from July to December 2004, in which, 50 Wistar childhood rats of clean grade and either sex were employed.METHODS: Coriamyrthin injection was administrated muscularly to duplicated chronic epileptic grand mal model in rats. Muscular injection was repeated once every three days. During modeling, those with general paroxysmal convulsion with posterior extremities standing or falling with standing or general stiffness-paroxysmal attack continuously for 3 times, the injection was changed to be once every 14 days. Ten rats were selected to be in normal control without modeling. The rest 40 rats after 3 months of modeling were randomized into 4 groups, named piracetam of 2.4 g/'L group (Group A), piracetam of 4.8 g/L group (Group B), dilantin 6 g/L +piracetam 4.8 g/L group (Group C) and model group (Group D), 10 rats in each. In each group, gastric infusion was performed continuously in 3 months after modeling, once per day, 10 mL/kg. In Group A and Group B,piracetam mixed solution of 2.4 g/L and 4.8 g/L was administrated for infusion respectively. In Group C, dilantin 6 g/L and piracetam 4.8 g/L were infused. In group D and the control group, normal saline 10 mL/kg was administrated. Relevant index determination was done 1 month after medication. Morris water maze test was performed to discover platform time and searching distance of epileptic rats, continuously for 3 days, twice per day. After test, the rats were sacrificed to collect brains to determine the content of acetylcholine in bilateral hippocampus. The activities of cholinacetyltranslase and acetylcholinesterase were determined with radioimmunity method.of acetylcholine in bilateral hippocampus and the activities of cholinacetyltranslase and acetylcholinesterase of rats in each group.ing platform time of rats in every group: the corresponding average searching time in Group D was increased compared with the control group [(63±11) s, (40±8) s; (61±9) s, (38±7) s; (57±8) s, (36±9) s; (55±11) s,(33±10) s; (52±7) s, (30±9) s; (49±9) s, (27±6) s, P ＜ 0.01]. In Group C and Group B, the searching time of 6 tests was decreased of various degrees compared with Group D [(44±9) s, (45±9) s;(43±9) s, (42±8) s; (42±7) s,(42±7) s; (40±9) s, (39±9) s; (38±7) s, (35±9) s; (35±6) s, (34±8) s,t=2.352-4.029, P ＜ 0.05-0.01]. In every medication group, the average searching time was decreased gradually by the increased frequency of erage searching distance in Group D was remarkably increased compared with the control [(793±74) cm, (420±81) cm;(763±89) cm, (418±57) cm;(690±67) cm, (382±69) cm; (623±81) cm, (356±71) cm;(592±98) cm,(330±69) cm;(550±54) cm,(301±97) cm,P＜ 0.01]. In Group C and Group B, the average searching distance of 6 tests was decreased of various degrees compared with Group D [(586±91) cm, (510±89) cm;(566±70) cm,(497 ±76) cm; (521 ±84) cm, (455 ±56) cm; (480 ±74) cm, (421 ±63) cm;(437±51) cm, (396±79) cm;(392±79) cm, (385±48) cm, t=2.364-4.230, P ＜ 0.05-0.01]. In every medication group, the average searching distance tent of acetylcholine in brain hippocampus and the activities of cholinacetyltranslase and acetylcholinesterase of rats in each group: those in Group D were all remarkably reduced compared with the control [(2.2±0.7) nmol/g,(3.8±0.9) nmol/g;(503.3±103.3) pkat/g, (778.3±125.0) pkat/g;(190.0±51.7) μkat/g, (368.3±86.7) μkat/g, P ＜ 0.01]. In mixed group and Group B, the content of acetylcholine and activity of acetylcholinesterase were remarkably higher than the Group D [(2.7±0.6) nmol/g, (2.9±0.6) nmol/g;(256.7±58.3) μ kat/g, (306.7±88.3) μkat/g, t=3.445-4.148, P ＜ 0.01]. In Group B, the activity of cholinacetyltranslase [(668.3±118.3) kat/g] was remarkably higher than those in the Group D(P ＜ 0.01). Every index in group A was basically same as model group.CONCLUSION: Grand mal of chronic epileptic rat model is characterized as declined capacity of spatial learning and memory and associated with decreased content of acetylcholine and the activities of cholinacetyltranslase and acetylcholinesterase in brain hippocampus, explaining the successful complex model of learning and memory disturbance. Piracetam 4.8 g/L may increase content of acetylcholine and the activities of cholinacetyltranslase and acetylcholinesterase in brain hippocampus and improve learning-memory capacity, but its effect at 2.4 g/L was not remarkable.

Objective To understand the prevalence of smoking in different sub-populations in Xuzhou area so as to develop effective tobacco control policies. Methods Through multi-stage randomized cluster sampling,a face-to-face study with standard questionnaire was carried out among residents aged above 15 years,from June to December 2008,with descriptive nature. Results Totally,44 686 people,with 21 524 males and 23 162 females at age 15 and over were investigated,including 34 391 of them from rural areas and 10 295 from the urban population. Data regarding rates on ever smoked and current smoking,regular smoking,heavy smoking,and average numbers of cigarettes smoked per day,types of tobacco products smoked,rates on quitting smoking successfully,relapse,passive smoke exposure etc.,were 22.45%,21.40%,15.49%,9.49%,15.09/d,4.68%,5.91% and 14.12% respectively. There were no significant differences in the rates of overall smoking,current smoking and regular smoking among urban and rural residents (P>0.05). However,rates of successfully quitting smoking and passive smoke exposure in the urban areas were higher than those in the rural areas (P<0.05). Rates regarding relapse,heavy smoking and average numbers of cigarettes smoked per day in the rural areas were higher than those in the urban areas(P<0.05). Rates on smoking,current smoking,regular smoking,heavy smoking,relapse and average numbers of cigarettes smoked per day were higher in males than those in females (P<0.05). Rates of quitting smoking successfully and passive smoke exposure were higher in females than those in males (P< 0.05). The major types of tobacco products smoked by people aged 15 years old and above were cigarettes (85.17%),and Chinese pipes (3.24%). Conclusion Smoking was quite common in people from Xuzhou. Our data suggested that health education should be strengthened and sustainable intervention measures be developed and implemented to control the tobacco use in the area.

Objective To investigate the characteristics of plaque morphology of the patients with unstable angina(UA)by intravascular ultrasound(IVUS). Methods24 patients with stable angina pectoris(SA)and 33 patients with unstable angina(UA)were examined by coronary coronary arteriograph(CAG)and intravascular ultrasound(IVUS).The culprit lesions about the characteristic of the plaque were studied,the external elastic membrane cross-sectional area and lumen cross-sectional area were measured,the plaque area,plaque burden,eccentricity index were calculated,and the remodeling index was examined. ResultsExternal elastic membrane area,plaque area and vascular remodeling ratio were significantly greater at target lesions in UA patients than in patients with SA(P＜0.05).Positive remodeling and soft plaque were predominantly in UA patients(P＜0.05). ConclusionThe morphological features of coronary artery plaques in UA group were significantly different from those in SA group.More soft plaque,plaque rupture,thrombus formation,and positive remodeling were found in UA patients compared with SA patients.

BACKGROUND:Pulmonary infection after kidney transplantation evolves rapidly. There is a high mortality rate in patients with server pulmonary infection. It has the important significance of early diagnosis and treatment of pulmonary infection, but some patients appear to have impaired kidney function because of the adjustment of immunosuppressants. OBJECTIVE:To explore the approaches to applying the immunosuppressants during the treatment of pulmonary infection after kidney transplantation. METHODS:The clinical data of 85 kidney transplantation patients who suffered from pulmonary infection were retrospectively analyzed. There were 43 cases in which the infection occurred within 1-6 months after kidney transplantation, 39 of which within 2-4 months; 7 cases of infection occurring within 6-12 months; 7 cases of infection within 12-24 months; 6 cases of infection within 24-36 months; 22 cases of infection occurring beyond 36 months. The immunosuppressant dose was adjusted based on a per-case basis. As a complement, the smal-dose hormone was used for anti-inflammation. Etiological treatments for resisting infections were also conducted accordingly. Ventilators were utilized for patients with respiratory failures. The body temperature of patients was monitored and controled. Appropriate nutrition support was also provided accordingly. There were 44 cases of decreasing or stopping the use of immunosuppressants during the early period of pulmonary infection; 19 cases of decreasing or stopping the use of immunosuppressants during the treatment of pulmonary infection;5 cases of stopping the use of immunosuppressants during the period of severe pneumonia; 15 cases of gradualy changing the dose of immunosuppressants during the early and progressive period of pneumonia; 2 cases of decreasing the use during the early period of pneumonia and stopping the use during the period of severe pneumonia. The duration of decreasing or stopping the use of immunosuppressants ranged from 3-51 days, with an average of 10.7 days. RESULTS AND CONCLUSION: Among the 85 patients, there were 81 cases cured and 4 cases of death. Among the four death cases, two cases died of acute respiratory failure and two cases died of multiple organ failure. Of the cured 81 cases, acute rejection occurred in 3 cases, while renal alograft dysfunction occurred in 6 cases. Decreasing or temporarily stopping the use of immunosuppressants during the treatment of pulmonary infection caused by the kidney transplantation increases the cure rate and decreases the mortality rate; while timely resuming the usage of immunosuppressants effectively protects the renal graft function, especialy for patients with renal graft dysfunction.
