This paper was aimed to study the method of rapid determination of total flavonoids in Chrysanthemum of different processing methods by near infrared spectroscopy (NIRS). The Chrysanthemum was dried by three different processes. The three methods were directly drying, drying after steamed and drying after fry, respectively. The determination of total flavonoids in Chrysanthemum by different processing methods was produced by using UV-Vis spectrophotometry. Collecting the NIRS spectra of Chrysanthemum, the quantitative analysis model of total flavonoids content in Chrysanthemum of different processing methods was established by partial least square (PLS) and the model was validated. The correlation coefficient (R2), the root-mean-square error of calibration (RMSEC) and the root-mean-square error of prediction (RMSEP) were 0.996 19, 0.104 and 0.168, respectively. The correlation coefficient of predication (r) was 0.979 3 which state that the prediction was accurate. The method of NIRS had the advantage of fast determination, simple operation and high accuracy of prediction, and could be used for rapid determination of total flavonoids content in Chrysanthemum of different processing methods.

Objective To study the influence of herbal decoction Shuxin Yin(SXY)on platelet activation of rats and mice with a- cute myocardial ischemia in order to explain its possible mechanism for treating coronary heart disease.Methods The rat model with acute myocardial ischemia and the mice model with acute myocardial ischemia and reperfusion were established.The male SD rats and ICR mice,51 each,were randomized into 5 groups respectively:sham operation group,model group,low dose SXY group,high dose SXY group,ticlopidine groap.Made models and collected blood Sample after 30 days gastric infusion in succession.The flow cytome- try technique and the monoclonal antibody examination were adopted to test the mice platelet glycoprotein CD_(62)P;the radioim- munoassay was used to test rat platelet aggregation rate(PAR),fibrinogen(Fg),thromboxane B_2(TXB_2)and 6-keto-PGF_(1?) and their ratio.Results Shuxin Yin can,inhibit the high expression of CD_(62)P of mice with acute myocardial ischemia and reperfusion,and de- crease PAR,Fg and TXB_2/6-keto-PGF_(1?) of rats with acute myocardial isehemia.Compared with the effect of ticlopidine,the differ- ence was not significant.Conclusion Shuxin Yin could effectively inhibiting platelet activation in rats anel mice with acute myocardial ischemia,and its effect in preventing and treating coronary heart disease might be related to the inhibition of platelet activation.

Objective To evaluated the prevalence of EGFR mutations in Hubei region,to provide reliable experimental basis for reasonable screening TKI beneficiaries in clinic.Methods EGFR mutation of 253 patients diagnosed with NSCLC in Hu-bei region during 2010 to 2015 was detected by PCR-sanger sequencing and ARMS assay,to investigate the sensitivity of dif-ferent methods,to explore the frequency and clinical significance of EGFR mutation in different gender,in different histologi-cal type and different exons.Results 93 of 253 NSCLC patients harbored EGFR mutation,mainly occurred in exon 19 and 21,accounting for 53.76% and 35.38% of the total EGFR mutation rate,respectively.ADx-ARMS method showed higher sensitivity (P=0.001).The mutation detection rate of female NSCLC was significantly higher than that of male NSCLC (P=0.001).The observed incidence of EGFR mutations in patients with adenocarcinomas (38.01%)was the highest in differ-ent histological type,followed by glandular squamous cell carcinoma (30.77%),large cell carcinoma (20%)and squamous cell carcinoma (4.55%).Nonsmoking patients had a higher EGFR mutation frequency (51.6%,81/157)than those with a history of smoking (24%,12/50).Conclusion ARMS assay was more sensitive and more convenient detection method for clinical screening for EGFR-TKI treatment subpopulation.The mutation rate of female NSCLC was significantly higher than that of male NSCLC in Hubei Province.Speculated that the sexual differences in NSCLC with EGFR mutation frequencies were related to hormone levels and smoking status.

Objective To compare the cerebral oxygenation in the patients undergoing gynecological laparoscopic surgery under sevoflurane-versus propofol-based anesthesia.Methods Fifty adult patients,aged 18-56 yr,weighing 55-72 kg,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,with hemoglobin≥ 110 g/L,undergoing elective gynecological laparoscopic surgery under general anesthesia,were equally and randomly divided into sevoflurane group (group S) and propofol group (group P) using a random number table.Anesthesia was induced with iv midazolam 0.04 mg/kg,sufentanil 1.5-2.0 μg/kg,rocuronium 0.9 mg/kg,and propofol 1.5-2.0 mg/kg.Anesthesia was maintained with inhalation of sevoflurane (2.0％-2.6％) in group S,or with target-controlled infusion of propofol (plasma concentration 2.5-4.0 μg/ml) in group P.The concentrations of sevoflurane and propofol were adjusted to maintain bispectral index value at 40-50.In both groups,remifentanil was given by targetcontrolled infusion (target plasma concentration 2 ng/ml),and vecuronium 0.06-0.08 mg/kg was injected intermittently to maintain muscle relaxation.The regional cerebral oxygen saturation (rSO2) was recorded after induction and at 10 min before pneumoperitoneum (T1),at 10 min of pneumoperitoneum in the Trendelenburg position (T2),and at 10 min after the end of pneumoperitoneum (T3).The occurrence of cerebral oxygen desaturation was recorded during surgery.Results The rSO2 was significantly higher at T2,3 in group S than in group P (P＜0.05).Compared with the value at T1,no significant change was found in rSO2 at T2,3 in group S (P＞0.05),and the rSO2 was significantly decreased at T2,3 in group P (P＜0.05).The incidence of cerebral oxygen desaturation was 12％ in group P,and cerebral oxygen desaturation was not detected in group S.Conclusion Sevoflurane-based anesthesia produces no effect on rSO2,however,propofol-based anesthesia can decrease rSO2 in the patients undergoing gynecological laparoscopic surgery,and sevoflurane-based anesthesia is more suitable for gynecological laparoscopic surgery.

Objective To study the expression and clinical significance of ezrin in breast carcinoma. Methods Immunohistuchemieal staining(S-P) was used to detect the expression of ezrin in 63 cases of breast car-cinoma samples. Results Among these 63 samples,the total expression rates of ezrin were 55.56% (35/63). With the increasing of axillary lymph nodes metastasis and clinical staging,the rates of expressing of ezrin elevated (P<0.05),which was remarkably lower in patients whose disease-free survival(DFS) was > 5 years,or those whose DFS≤5 years or died within five years(P<0.05) ,but the expression of ezrin was not correlated with tumor size,age and menopausal status (P>0.05). Conclusion The expression of ezrin may contribute to prognostic e-valuation for breast carcinoma.

Objective To provide theoretical and experimental proof for selecting and implying Tourette's syndrome(TS) animal models, validities of four TS models induced by chemical factors were compared. Methods Four TS models,namely AMP model,APO model,DO1 model and IDPN model were built up by using different chemical modeling agents. Through detecting spontaneous movement, climbing time and monoamine transmitters levels in striatum, four TS animal models were compared and evaluated from three levels of validities-face, prediction,construct. Results Compared with control group, spontaneous movement times raised ( t = 4. 746, P =0. 000) and level of DOPAC ( (0.99 ± 0. 177 ) ng/mg) in striatum increased (P = 0.029 ), and level of NE in striatum decreased in AMP model group( (0.11 ± 0.033 )ng/mg, P = 0.012). Compared with control group, climbing time prolonged (P = 0. 004) and levels of DA ( ( 10. 19 ± 1.23 ) ng/mg), 5-HT ( ( 0. 54 ± 0.08 ) ng/mg) in striatum raised(P=0. 019, P=0. 002),at the same time ,levels of DOPAC( (0.63 ±0.11 )ng/mg),HVA ((0.45 ±0.04 ) ng/mg) in striatum reduced (P ＜ 0.01 ) in APO model group; Compared with control group, levels of DA ( ( 13.66 ± 1.55 ) ng/mg), DOPAC( (0.80 ±0. 11 ) ng/mg), HVA( ( 1.04 ± 0.14) ng/mg) grew downwards in striatum of DOI model mice(P=0.029,P=0.001, P= 0.004). Compared with control group, level of 5-HT in striatum increased in IDPN300 group ( (0.77 ± 0.09) ng/mg, P = 0.031 ). ConclusionFace validity of AMP model is temporal and that of IDPN model is steady and persistent. AMP model,APO model and DOI model possess predictive validity. AMP model,APO model,DOI model and IDPN model have potentiality of becoming construct validity model.
