Objective:To study the surface enhanced Raman scattering ( SERS) of safflower and identify safflower injections by SERS quickly and effectively. Methods:Through comparative analysis of the Raman spectroscopy of safflower injections and the corre-sponding control herbs, the rapid identification of safflower injections was realized. Results:The results showed that several character-istic peaks of safflower were enhanced obviously in SERS, which could be used to identify safflower injections. Conclusion:The meth-od is reliable, rapid, accurate and specific, which can be applied as a method to identify safflower and its injections.

Objective To compare the clinical features of myocardial infarction (MI) in young adults with and without diabetes. Methods A total of 94 young adults with MI were enrolled in this study and divided into two groups according to whether they had diabetes:diabetic group (DM) and Non diabetic group (NDM).The clinical features,angiographic results,risk factors and prognosis were compared between the two groups. Results The incidence of atypical chest pain (25.0% vs 7.6%),non-ST segment elevation myocardial infarction (50.0% vs 9.1%),ventricular wall motion abnormalities (78.6% vs 42.4%),double vessels (35.7% vs 21.2%),triple vessels (39.3% vs 3.1%) and the incidence of mortality(10.7% vs 1.5%)were all significantly higher in DM group than in NDM group (P<0.05 or P<0.01).The number of affected vessels and Gensini scores were (2.110±0.875) and (52.61±10.47) in DM group,and(1.140±0.677),(34.02±10.24) in NDM group.The between group difference was statistically significant (P<0.05).Multiple linear regression showed that HbA1c and smoking were the independent risk factors for Gensini score. Conclusion The clinical features of young adult patients with MI and diabetes are more complex,their coronary stenosis are more serious,and the prognosis is poor.Smoking and HbA1c are positively associated with Gensini scores.

ObjectiveIn order to confirm the relationship of pathogenic factors and clinical manifestation of cerebral palsy. Methods185 children were divided into the prematurity group(91 cases) and maturity group(94 cases). The μ-test was applied to analyze the incidence of clinical manifestation of 185 children with cerebral palsy for different pathogenic factors. ResultsThe sever symptoms occurred more frequently in prematurity group than in maturity group. ConclusionThe earlier the careful follow-up for children with prematurity was performed, the earlier the diagnosis and treatment of cerebral palsy were achiened.

Objective To establish the analytical methods for determining the contents of tannins in different vegetative organs of Abutilon indicum (L.) Sweet. Methods The content of tannins, expressed as gallic acid equivalents, was measured by using the phospho molybdenum tungstic acid-casein colorimetry. Results The good linearity between concentrations and absorbances of gallic acid was found in the range of 2～10 mg/L, the average recovery was 99.63% and RSD was 1.08%, the contents of tannins in leaves, stems and roots of Abutilon indicum (L.) Sweet were 0.34%, 0.16% and 0.27% respectively. Conclusion The proposed method is sensitive, precise, accurate and reproducible, and it is suitable for the determination of tannins in Abutilon indicum (L.) Sweet.

Objective To investigate the intelligence level and its structure of children with cerebral palsy, and to discuss the effect of degree on them. Methods The intelligence function of 45 children with cerebral palsy was tested by means of Wechsler Intelligence Scale for Children-Chinese Revised ~WISC-CR). The total IQ, verbal IQ, performance IQ and Bannatyne four factors were analyzed and compared among the children grouped on the basis of severity of their dysfunction. Results For children with cerebral palsy, the total IQ ~70.02?(19.50)) was lower than that of the normal children, the ratio of mental deficiency was 55.6%; their verbal IQ was higher than performance IQ ~79.80?18.88 vs 64.24?19.28),P

Objective To study the relationship of plasma homocysteine (Hcy), polymorphism in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine-?-synthase (CBS) genes, and cerebral infarction in the elderly. Methods 61 elderly patients with first-ever acute cerebral infarction and 57 controls were studied. The plasma Hcy levels were measured using high-performance liquid chromatography-fluorescence detection (HPLC-FD). The polymorphism in MTHFR was determined by a polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion.CBS was determined by amplification refractory mutation system (ARMS). Results The fast plasma Hcy levels were higher in the patient group compared with those in the control group [(13.07?3.96)?mol/L vs (11.51?3.90)?mol/L, P 0.05). There were no differences in the plasma Hcy levels among the different genotypes. Conclusions The MTHFR, CBS gene mutations cannot lead to hyperhomocysteinemia in the elderly patients with acute cerebral infarction. Hyperhomocysteinemia is associated with the independent risk of cerebral infarction, however, mutations only in MTHFR and CBS cannot be ascertained to be independent risk of cerebral infarction in the elderly.

Objective To explore the feasibility of laparoscopic operations in the treatment of ovarian benign tumors. Methods A retrospective analysis of 150 cases of ovarian benign tumors treated by laparoscopic surgery (146 cases of oophorocystectomy and 4 cases of adnexectomy) from January 1997 to October 2003 was made. Results Surgery was completed successfully in all the 150 cases and no conversions to open surgery were required. Mild extraperitoneal emphysema was observed in 2 cases and no other complications occurred. The mean blood loss was 100 ml, the mean operation time was 80 min, and the mean length of hospitalization was 4 3 days. A total of 128 cases were followed up for a mean of 3 8 years. Recurrence was found in 4 cases in 38 cases of endometriosis cysts. Among 15 patients complicated with infertility, conception occurred in 6 patients after surgery, with a pregnancy rate of 40%. Conclusions Laparoscopic surgery is safe and effective for ovarian benign tumors provided patients are properly selected.

Objective To explore the relationship between plasma homocysteine(Hcy) levels and cerebral infarction.Methods 87 patients with acute cerebral infarction and 80 controls were enrolled in the study. Plasma Hcy levels were measured by high-performance liquid chromatography-fluorescence detection(HPLC-FD) technology using Baseling 810 type high-performance liquid chromatograph.Results Fast plasma Hcy levels were higher in the patient group[(15.28?4.33)?mol/L] compared with those in the control group[(11.32?3.86) ?mol/L]( P

Objective To evaluate the effects of reminfentanil combined with propofl on patients received video assisted thoracoscopic surgery. Methods 40 ASA Ⅰ～Ⅱ patients underwent video assisted thoracoscopic surgery were randomly divided into two groups. BP、HR before anesthesia induction(T0) ,tracheal induction(T1) ,tracheal induction instantly (T2), after five minutes of tracheal induction(T3) were observed; The time of breathing recovery withdrawl,and open eye,extubation and instantly of extubation,VAS;to record in the operation and adverse effect of postoperative nausea were analyzed. Results During tracheal induction, hemodynamic and respiratory variables of groupR less then group F(P ＜ 0. 05), after operation group R time of breathing recovery withdrawl, and open eye, extubation is short of group F(P ＜ 0. 05). Two groups was not appear to know in operation, postoperative nausea is not satistically significant. Conclusion General anesthesia by reminfentanil combined with Propofol on video assisted thoracscopic surgery was safe and feasible.
