Objective To explore the mechanism of shengmai injection on relieving ischemia reperfusion injury and antagonizing systemic inflammatory response syndrome by regulating cytokines when it was applied at the early stage of cardiopulmonary resuscitation(CPR).Methods 40 cases suffering from cardiac arrest and had their heart beat recovered through CPR for more than 24 hours were randomly divided into SMI group and control group(20 cases for each).The patients in the two groups were treated with common therapeutics based on the CPR,but the patients in SMI group were intravenously dropped with SMI in the early period of PLS phase,then the changes of serum concentration of TNF-α and IL-81h,2h,6h,12h and24h after CPR in the two groups was compared.Results The concentrations of serum TNF-α and IL-8 stepped up gradually after resuscitation and the levels of TNF-αand IL-8 in SMI group were lower than that of the control group at 1h,2h,6h,12h and 24h after resuscitation(P＜0.05).Conclusion SMI functions to relieve ischemia reperfusion injury by regulating cytokines and antagonizing systemic inflammatory response syndrome.

Objective To evaluate the effect of meglumine cyclic adenosine (MAC) on heart rate variability (HRV) in aged-patients with coronary heart disease (CHD).MethodsSeventy six aged-patients with CHD were randomly divided into control group (n =36) and treatment group (n =40).The patients in control group were treated with nitrate,ozagrel,calcium antagonist,aspirin enteric-coated tablets,low molecular heparin,angiotensin-converting enzyme inhibitor ( ACEI ) or angiotensin receptor antagonist ( ARB ) and lipidlowering agents according to patients' conditions.Based on this,the patients in treatment group were treated with MAC 90 mg intravenous injection once a day for two weeks.The 24 h dynamic electrocardiogram was recorded.pre-ard post-treatment,and the changes of HRV indexes were observed.Results There was no statistical significance in HRV between the two groups before treatment ( P ＞ 0.05 ).However the HRV in two groups improved significantly after treatment ( P ＜0.01 ).The improvement of HRV was more significant in MAC group than that in control group (P ＜0.01 ).Conclusion MAC can significantly improve HRV in aged-patients with CHD.

Blood samples were detected by 24 blood-glucose meters using glucose oxidase and another 18 glucose meters using glucose dehydrogenase. The plasma glucose was detected by the auto-chemistry analyzer as control. According to ISO1 5197 and EF9-A2, the bias of results from both glucose meters 100% fall in the range of ±0. 56 mmol/L( ＜4. 2 mmol/L) and ≥99. 7% in the range of ±20% ( ≥4. 2 mmol/L), predicted bias were all less than the true bias(Bc). As κ＞0. 6, the results from both glucose meters were in accordance with the results from autochemistry analyzer in judging hyperglycemia ( ＞6. 11 mmol/L) and hypoglycemia ( ＜ 3.89 mmol/L). Between the results from the two blood-glucose meters, κ＜0. 6. The accuracy of both glucose-meters are accepted for the purpose of clinical diagnosis and treatment.

Objective To investigate the pharmacodynamics of different local anesthetics administered intrathecally for elderly patients undergoing transurethral resection of the prostate (TURP). Methods Ninety ASA Ⅰ - Ⅲ elderly patients, aged 69-82 yr, with body mass index less than 30 kg/m2 , undergoing TURP under combined spinal-epidural anesthesia, were randomly divided into 3 groups ( n = 30 each): levobupivacaine group (group L), ropivacaine group (group R) and bupivacaine group (group B). Group L, R and B received intrathecai (IT) 0.5 % levobupivacaine, 0.5 % ropivacaine and 0.5 % bupivacaine respectively. The initial dose was 7,10 and 6 mg in group L, R and B respectively. The ratio of two successive doses was 0.9. If the upper sensory block reached T10 within the 20 min after IT injection, the IT analgesia was considered to be effective. The median effective dose (EDs0) and 95 % confidence interval (95 % CI) were calculated by Dixon. Results The ED50 and 95% CI of levobupivacaine, ropivacaine and bupivacaine were 6.781 (95% CI 6.561-7.024) mg, 9.135 (95%CI8.670-9.616) mg and 5.170 (95% CI 5.012-5.333) ng respectively. The relative potency ratio between levobupivacaine, ropivacaine and bupivacaine is 0.76∶0.57∶1.00. ConclusionThe relative potency ratio be tween levobupivacaine, ropivacaine and bupivacaine is 0.76∶0.57∶1.00.

Objective To observe the change of peripheral blood CD34+ cell level in patients with acute cerebral infarction, and explore its relationships with cerebrovascular risk factors,neurological function and carotid artery intima-media thickness (IMT). Methods The 45 patients with acute cerebral infarction (onset within 72 h) (infarction group) and 27 patients with cerebr ovascular risk factors but without cerebral infarction (high-risk group) were chosen for the study. The cerebrovascular disease risk factors including history of alcohol abuse, smoking, coronary heart disease, hypertension, diabetes, abnormal levels of serum triglycerides, total cholesterol,low-density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) were recorded in all subjects. The peripheral blood CD34+ cell levels were measured by flow cytometry.The correlations of peripheral blood CD34+ cell level with cerebrovascular disease risk factors were analyzed. The neurological function and carotid artery IMT were recorded in infarction group, and the correlations of peripheral blood CD34+ cell level with neurological function and carotid artery IMT were analyzed. Results (1) The peripheral blood CD34+ cell level was significantly negatively correlated with coronary heart disease, hypertension, diabetes and LDL-C level (r =- 0. 749,-0. 717, - 0. 688, - 0. 764, all P＜0. 01) ; (2) Multiple linear regression analysis showed that peripheral blood CD34+ cell level was an independent relative factor of acute cerebral infarction (P＜0.05); (3) The peripheral blood CD34+ cell level was lower in infarction group than in high-risk group, and was significantly negatively correlated with neurological deficit score (r=-0. 721, P＜0.01) and carotid artery IMT (r= -0. 695, P＜0. 01). Conclusions Peripheral blood CD34+ cell level could be an independent relative factor of acute cerebral infarction; The peripheral blood CD34+ cell level is significantly negatively correlated with neurological function and carotid artery IMT in patients with acute cerebral infarction; And it can be used as cytological marker which reflect early vascular endothelial function in patients with ischemic stroke.

Objective To determine the level of peripheral blood CD34 positive (CD34+) cells in patients with acute cerebral infarction (ACI),and to explore its clinical significance.Methods The level of peripheral blood CD34+ cells was determined by flow cytometry within 72 hours of onset of patients with acute cerebral infarction (infarct group,n=45),cerebrovascular risk factors in patients without cerebral infarction (high risk group,n=27) and healthy subjects (control group,n=20).The neural function defect score,infarction lesion volume and carotid artery intima-media thickness (IMT) were determined in patients with infarction group.Results The percentages of peripheral blood CD34 cells in infarction group (0.034 ±0.012)％ and the high risk group of patients (0.047±0.009)％ were lower than that of control group(0.063±0.009)％,and were lower in infarction group than in high-risk groups (all P＜0.05).The percentages of peripheral blood CD34+cells were significantly decreased compared with control group (P＜0.05) in infarction patients with mild [(0.047±0.009)％],moderate [(0.036±0.009)％],severe [(0.022±0.007)％] infarction nervous function defect score.Wherein,the percentages were lower in severe group than in the moderate group,moderate group was lower than in mild group (all P＜0.05).The percentages of peripheral blood CD34 cells in infarction patients with small,moderate,large infaret lesion volume were lower than in control group (P＜0.05),wherein,were lower in large group than in moderate group,lower in moderate group than in treatment group (all P＜0.05).Infarction patients were confirmed with carotid atherosclerosis (CAS) by carotid ultrasound.The extent of lesion were divided into carotid artery intimal thickening group [(0.043±0.010)％],carotid artery plaque group [(0.036±0.010)％],and carotid artery stenosis group [(0.023±0.009)％].The levels of peripheral blood CD34+ cells in three groups of patients were decreased compared with control group.The levels were lower in carotid artery stenosis group than in carotid artery plaque group,lower in carotid artery plaque group than in carotid artery intimal thickening group (all P＜0.05).Conclusions The level of peripheral blood CD34+ cells in acute cerebral ischemia is reduced,it can become a sensitive and early indicator of cerebral ischemia,and its level is related to neurologic impairment,infarction size and the degree of carotid artery atherosclerosis.

Objective To investigate the causations, management and prevention methods on the complications of hysteroscopic procedures. Methods Retrospective analysis of 36 cases with hysteroscopic complication, focusing on their characteristics and clinical management as well as prevention methods during the ten years from 1993 to 2004. Results Among 36 cases, 11 cases with uterine perforation and incomplete perforation, which happened during the complicated procedures, were treated by both laparoscopy and laparotomy. Five cases with heavy bleeding were encountered because of the deeply injury to the uterine wall and Foley catheter was inserted into uterine cavity and it stopped the bleeding successfully except in one case done by hysterectomy. Three cases with fluid overload syndrome were cured by using diuretic agent and saline infusion. There is no serious consequence in one case with air embolism due to prompt diagnosis and treatment. Four cases with postablation-sterilization syndrome were treated effectively by performing hysterectomy plus single or bilateral salpingectomy, dilating cervical canal as well as resecting adhesions. Twelve cases with adhesion inside uterine cavity followed hysteroscopy were also treated by dilating cervical canal, underwent adhesionlysis and hysterectomy. Conclusions The potential factors causing complications of hysteroscopy include complicated procedures inside uterine cavity, higher pressure of irrigation, deep injury of endometrium as well as incomplete removal of endometrium during hysteroscopic operations. It is the necessary measures to reduce the complications by performing laparoscopy or B ultrasound monitoring simultaneously, standardizing the procedure and strengthening postoperation management.

Objective To investigate the status of sleep quality and the family-related factors among elder-ly pregnant women who already have one child.Methods A total of 299 elderly pregnant women who already have one child were investigated using pittsburgh sleep quality index(PSQI),family APGAR index and a self-designed questionnaire. Results The total prevalence of poor sleep quality was 30.8% among elderly pregnant women who already have one child.PSQI score was average(6.31 ± 2.95). PSQI score were higher than the adult female norm and pregnant woman for the first time(u=16.396,5.497,P<0.05).Univariate analysis showed that the determi-nants of sleep quality included pregnancy,family support(parents),family support(husband),family support (child),family dysfunction,family right(χ2= 12.312,21.049,18.617,11.682,13.494,6.779,P < 0.05). Logistic regression analysis showed that pregnancy,family support(parents),family support(husband),family support(child)and family dysfunction were associated with sleep quality. Conclusion The poor sleep quality among elderly pregnant women who already have one child is related to low family support(parents,husband, child),obstacle of family dysfunction and late pregnancy.

Objective:To investigate the family gene features in Crigler-Najjar syndrome (CNS) type II.Methods:The UGT1A1 gene and related bilirubin metabolism genes were comprehensively analysed in a CNS-II family (3 CNS-II, 1 Gilbert syndrome, and 8 normal subjects). The genetics basis of CNS-II were investigated from the perspective of family analysis. Results:In three cases, compound heterozygous mutations at three sites of the UGT1A1 gene (c.-3279T > G, c.211G > A and c.1456T > G) caused CNS-II. Gilbert syndrome and CNS-II were not significantly associated with distribution or diversity loci. Conclusion:The compound heterozygous pathogenic mutations (c.-3279T > G, c.211G > A, and c.1456T > G) at three loci of the UGT1A1 gene may be the feature of the newly discovered CNS-II family genes based on the CNS-II family study.
