Objective To establish HPLC fingerprint for the identification of Semen Cassiae. MethodsChromatographic fingerprint of Semen Cassiae was investigated by RP-HPLC and the gradient elution mode was applied to chromatographic separation. Data were analysed by fingerprint similarity evaluation software to compare the similarity of the samples. ResultsThe HPLC fingerprint of Semen Cassiae was established preliminarily. ConclusionHPLC Fingerprint method is repeatable and can be used in quality control of Semen Cassiae.

Objective To evaluate the effects of controlling arterial oxygen partial pressure (PaO 2) at the beginning and during cardiopulmonary bypass (CPB) on cyanotic myocardial protection. Methods 40 Children suffering from tetralogy of Fallot(TOF) under 3 years of age with SpO 2

6, 39 cases were with 3～6, 13 cases were with the number less than 3. The diameter of stones was 0.5～1.2 cm. Five cases suffered from bile leakage, 2 cases from peritonitis and 2 cases from remnant stones in the common bile duct. Forty-one patients were followed up and doing well. Conclusions Surgical approach is choosen on the basis individually. Laparoscopic common bile duct exploration for gallstone concomittant with choledocholithiasis is safe.

Objective To evaluate the effect of biofeedback therapy for the treatment of myogenic fecal incontinence. MethodsA general assessment about anorectal function was made on 17 cases receiving biofeedback therapy including muscle power training,sensory training and coordination training. Results The clinical scores before and after biofeedback therapy were 1.66?0.23,3.80?0.42 respectively,with an effective rate of 82%. The anus maximum contracting pressure elevated,(73?20) mm Hg vs. (123?30) mm Hg; myoelectric amplitude increased,(122?32) ?V vs. (230?41) ?V;Contracting time prolonged,(4.1?2.0) s vs. (9.4?3.0) s; The sensory threshold was lowered,(50?12) ml vs. ( 20? 10) ml;The feel-contract time increased,(3.1?0.4) s vs. (1.2?0.3) s. Positive rectal contraction reflex was seen in 41% patients before therapy compared with 82% after therapy. Conclusions Biofeedback therapy increases contractility of sphincter,decreases threshold of rectal sensory,and is a therapy of choice for myogenic fecal incontinence.

Objective To study the expression and significance of vascular endothelial growth factor(VEGF) in serum of umbilical blood from the newborns of women with severe pre-eclampsia.Methods Radioimmunoassay was used to measure the serum VEGF of umbilical blood from 26 newborns of women with severe pre-eclampsia (severe pre-eclmpsia group) and 30 newborns of normal pregnancy women (control group). According to birth weight-gestational age relation,severe pre-eclampsia group included 15 newborns small for gestational age (SGA group) and 11 newborns appropriate for gestational age (AGA group).Results (1)The VEGF level of umbilical vein blood and umbilical artery blood in severe pre-eclmpsia group was significantly higher than that in control group respectively(t = 2.16, P < 0.05;t = 4.82, P < 0.01). (2) In control group and severe pre-eclampsia group, the VEGF level in umbilical artery blood was significantly higher than that in umbilical vein blood (control group: t = 2.24, P < 0.05;severe pre-eclampsia group: t = 3.00, P < 0.01). (3)In both control group and severe pre-eclampsia group, there was no significant correlation respectively between VEGF levels in umbilical vein blood or umbilical artery blood and newborns' gestational age or birth weight. (4)VEGF level of umbilical artery blood in SGA group was significantly higher than that in AGA group as well as in control group(t = 3.22, P < 0.01 ;t = 6.80, P < 0.01). Conclusions The serum VEGF level of umbilical vein blood and umbilical artery blood from the newborns of women with severe pre-eclampsia was significantly higher than that of normal pregnancy women respectively. The VEGF level of umbilical artery blood can reflect the severity degree of the damage of hypertensive disorder complicating pregnancy to their newborns to some degree.

Objective To evaluate the diagnostic value of N-terminal pro-brain natriuretic peptide (NT-proBNP) quantitative detection in patients with heart failure.Methods Quantitative enzyme-linked immunosorbent assay (ELISA) improvement method was applied to measuring serum level of NT-proBNP in patients with different degree of heart failure.Results The serum level of NT-proBNP was significantly elevated in patients with heart failure. With the increase of extent of heart failure, NT-proBNP increased in exponent. Receiver operator characteristic curve (ROC) showed that area under curve (AUC) was 0.898. The sensitivity and specificity were 91.9% and 92.3% respectively for diagnosis of heart failure.Conclusion Quantitative detection of NT-proBNP is at present the best laboratory test for evaluating heart function of patients with heart failure.
