Objective To imporve the quality standard of Lianqiaobaidu Pills. Methods The TLC method was established for ephedrae herba, sophorae flavescentis radix, paeoniae radix rubra, and RP-HPLC methed was established for the determination of chlorogenic acid in Lianqiaobaidu Pills. Zorbax SB-C18 (4.6 mm×150 mm, 5 μm) column was used with methanol-acetonitrile (2∶1) - 0.04% phosphoric acid (10∶90) as the mobile phase at flow rate of 0.8 mL/min. The detection wavelength was 326 nm. Results TLC chromatographic spots were clear, and negative control had no interference. The linear range of chlorogenic acid was 0.042 2-0.464 2 μg (r=1), the average recovery (n=6) was 98.96%. Conclusion The method is simple, reliable, with strong exclusive feature, and suitable for quality control of Lianqiaobaidu Pills.

Objective To discuss the effect of problem-based learning(PBL)model in Neurological history collection.Methods PBL model was performed in Neurological class during the period of novitiation,and estimated by the students.Results PBL model has more advantages in improving autonomous study motivation,and brings up accurate clinical learning method.Con-clusions Compared with the traditional model,PBL model was more suitable for the development of modern medical medicine.

Objective To investigate the symptoms, signs and distribution of focus in acute insular infarct syndrome, as well as the effects on cardiovascular system. Methods The clinical manifestations of 20 patients with first-event acute insular infarct syndrome were analyzed retrospectively. Results All the patients revealed the intellectual deterioration, aphasia, hemiparalysis, sensory disorder and vestibular-like symptoms. The temporal lobes were mostly involved (65%). Electrocardiogram showed ST segment depressed mostly. The supraventricular premature beats were the most frequence finding by Holter monitoring in left insular infarction except atrial fibrillation, and their heart rate variability indicated that the standard deviation of normal-to-normal intervals (SDNN) decreased, but root mean square successive difference (RMSSD) increased. Conclusion The insular infarct syndrome can be charactered as a group of symptoms of intellectual deterioration, aphasia, hemiparalysis, sensory disorder and vestibular-like symptom. Left insular infarct could be complicated with arrhythmia, which increases the risk of adverse cardiac outcome. The characteristics of arteries to Sylvian angle may be associated with the syndrome.

Objective To understand changes of serum creatase zymogram of measles in children with or without vaccination histories and their clinical significances and approach the protection of vaccination on myocard of children with measles. Methods Seventy-one hospitalised cases with measles were classified into measles-vaccinated group (n=23), non-vaccinated group (n=48),and 30 healthy children were selected as healthy control group.Serum creatine kinase (CK) and isodynamic enzyme (CK-MB), lactate dehydrogenase (LDH) and isodynamic enzyme1 (LDH1), ?- hydroxybutyrate dehydrogenase (?- HBD)in 3 group were detected with electrocardiography and clinical analysis was made.Results Compared with those in vaccinated group, CK-MB, LDH1 and ?-HBD in non-vaccinated group advanced remarkably (Pa

AIM:To investigate the efficacy of controlled continuous curvilinear capsulorhexis(CCC) technique in short axial length and shallow anterior chamber eyes.METHODS:Sixty-eight patients(68 eyes) with short axial length and shallow anterior chamber were included.The routine CCC technique was used in 32 cases (32 eyes) and controlled CCC technique was used in 36 cases (36 eyes).The success rate and complication were compared between two groups. RESULTS:The success rate of the routine technique group and controlled technique group was 53. 13% and 86.11% respectively. Incomplete CCC leading to posterior capsule tears was 9.38% and zero in two groups respectively.CONCLUSION: Controlled CCC technique can increase the success rate and reduce complications in short axial length and shallow anterior chamber eyes.KEYWORDS:phacoemulsification; continuous curvilinear capsulorhexis; complication

Organic solvent tolerant microorganism(OSTM) is a novel extremophile and it hasn't been systematically studied until 1980s.Relying on certain mechanisms,the OSTM is able to effectively de-fend and decrease the toxicity from organic solvents,which enable the OSTM to be potentially applied in the industrial fields such as whole-cell catalysis and environmental treatment,etc.The comprehen-sively understanding of the mechanisms involved in organic solvent tolerance of OSTM could be com-bined with genetic engineering in order to modify and optimize the various specifications of OSTM,and further broaden its application in other industrial areas.Latest studies on the tolerant mechanisms of OSTM,in this paper,will be reviewed from four aspects such as vesicle exocytosis and changes of phos-pholipid composition in membrane,etc.Besides,the application of OSTM in whole-cell catalysis and other fields will be introduced.

Objective To investigate the role of hydrogen sulfide (H2S) synthases/H2S pathway in the pathogenesis of renovascular hypertension.Methods Wistar rats were subdivided into 4 groups:(1) 2-kidney,1-clip (2K-1C group,n=7),(2) control (n=7),(3)sham (n=7),and (4) 2K-1C plus sodium hydrosulfide (NariS) (NariS-treated group,n=7).The systolic blood pressure (SBP) was measured by a tail-cuff method using a pulse transducer once a week.Four weeks later,all rats were killed and the concentration of plasma hydrogen sulfide (H2S),the activity of the H2S syntha.ses in the kidneys on both sides,the plasma angiotensin Ⅱ concentration,and the left-to-whole heart weight ratio were measured.Results The SBP was significantly increased in the 2K-IC group (185.4± 14.0mmHg) comparing with those in the sham group (112.9±6.5mmHg,,or the NariS-treated group(134.8±9.5mmHg) (both P＜0.01).At 4 weeks,the angiotensin Ⅱ concentration in the plasma was increased in the 2K-1C and NariS-treated group,comparing with the control and the sham group (306.92±7.03 pg/ml and 240.73±13.22 pg/ml vs 122.6±25.49 pg/ml and 125.95±10.55 pg/ml,respectively,both P＜0.05).The plasma H2S concentration and the activity of H2S synthases in the left kidney were decreased in the 2K-1C group comparing with those in the sham and the control groups.There was no difference of the activity of the H2S synthases in the right kidneys among the 4 groups.The left-to-whole heart weight ratio was increased in the 2K-1C and the NariS-treated group camparing with that in the sham and natural control groups.Conclusions Dysfunction of the H2S synthases/H2S pathway was involved in the 2K-1C-induced renovascular hypertension in rat.Exogenous administration of H2S donor can attenuate the development of hypertension.These findings suggest that the H2S synthases/H2S pathway participates in the pathogenesis of renovascular hypertension.

To investigate the rehabilitating effect of acupuncture plus kinetotherapy for early hemiplegia due to cerebral apoplexy. Methods:Fifty cases of apoplectic hemiplegia were treated by acupuncture plus kinetotherapy and were compared with another fifty cases treated by single medications,in the therapeutic effect and for follow-up observation. Results:After the treatment for one month on average,the remarkable effective rate was 82% in the rehabilitation group and 54% in the control group,in a significant difference (P＜0.05). After the treatment,the scores in the motor function of the limbs and daily life ability were obviously increased in the rehabilitation group,and there was a significant difference in comparison with the control group (P＜0.05). Moreover,there was a good regulatory effect on blood rheology and blood lipid in the rehabilitation group. Conclusion:A combination of acupuncture and kinetotherapy has a better effect on apoplectic hemiplegia than single medications.
