AIM: To establish the content determination method of matrine and phillyrin in Jieyinjing Suppositories(Radix Sophorae Flavescentis,Fructus Forsythiae,Cortex Phellodendri Chinensis,Radix Stemonae,etc.) by HPLC. METHODS: HPLC was performed to determine matrine on ODS column,the mobile phase consisting of methanole-0.02% triethylamine(55∶45) and detection wavelength at 220 nm and the phillyrin of mobile phase consisting of acetonitrile-water(25∶75) and its detection wavelength at 277 nm. RESULTS: The linearity of matrine was in the range of 9.8 ?g?mL~(-1)-49.0 ?g?mL~(-1)(r=0.999 96),and the average recovery was(99.48%,) RSD=1.49%;The linearity of phillyrin was in the range of 5.4 ?g?mL~(-1)-54.0 ?g?mL~(-1)(r=(0.999 9),) and the average recovery was 100.07%,RSD=1.34%. CONCLUSION: This method is simple,sensitive and accurate,and available for control of Jieyinjing Suppositories.

Objective To investigate the effect of puerarin on preeclampsia-like rat placental tissue hypoxia inducible factor (hypoxia-inducible factor,HIF)-1αexpression and study the mechanism of protective effects in rats.Methods 60 SD rats were randomly divided into control group,drugs intervention groups(low-dose,middle-dose,high dose)and model group.The rats in drugs intervention groups and model group were adopted endotoxin for induction of preeclampsia model.On the basis of the model group,low,medium and high dose groups were given 20.0,40.0,60.0 mg/kg puerarin by intraperitoneal injection,respectively.The blood pressure of tail artery,urine protein concentration were observed at different points and the expression of HIF-1αwere detected by PT-RCT in each group.Results The systolic blood pressure ,urine protein and HIF-1αprotein in model group were higher than control group(P<0.05 );serum NO concentration was lower than control group (P<0.05 );after the puerarin intervention,systolic blood pressure and urine protein concentration in drugs intervention groups were lower than model group (P<0.05 ),plasma NO concentration was higher than model group (P<0.05 )and HIF-1αprotein was lower than model group (P<0.05 );the placenta weight,weight and body length of newborn rats in drug intervention group were higher than model group (P<0.05 ).Conclusion Puerarin can reduce systolic blood pressure and urine protein levels,promote the level of NO in plasma and reduce HIF-1αlevel in placenta of rats.Puerarin can offer protection to rats with preeclampsia by decreasing the expression of HIF-1αin placental.

Objective To establish a method for the content determination of naringin in Bogu Pill by HPLC. Methods At room temperature and by using ultrasonic extraction, HPLC was performed to determine naringin content on ODS chromatographic column.The mobile phase consisted of a mixture of acetonitrile and 8 % acetic acid (15 ∶ 85)and detection wavelength was at 283 nm.Results The linearity of naringin was in the range of 5.2 ? g / mL～ 31.2 ? g / mL (r=0.9999) and the average recovery was 98.72 % , RSD=1.55 % . Conclusion This method was simple, sensitive and accurate, and can be used for the quality control of Bogu Pill.

Objective To investigate changes in serum bilirubin and internal environment,etc.of neonatal hyperbilirubinemia that before and after the treatment of peripherally arteriovenous synchronous exchange transfusion. Methods In the strict monitoring of vital signs,hyperbilirubinemia peripheral vessels exchange transfusion was applied in five cases of neonatal,and the serum bilirubin,routine blood test,electrolytes before and after the exchange transfusion were detected.Results By comparing the data before and after the exchange transfusion,the total bilirubin and indirect bilirubin decreased obviously,respectively[(414.02 ±56.04)μmol/L,(225.72 ±53.54)μmol/L,t =5.433 P =0.01,(381.82 ±44.68)μmol/L,(199.22 ±57.37 )μmol/L,t =5.615 P =0.01 ],the difference was statistically significant,and also the platelet count were decreased obviously,respectively [(199.00 ± 42.01)×109 /L,(102.00 ±17.72)×109 /L,t =4.758,P =0.001],the difference was statistically significant.After the exchange transfusion,white blood cells,hemoglobin,potassium,sodium,chloride,calcium,glucose,blood pressure, heart rate and blood PH value had decreased or increased slightly,there was no significant difference P >0.05.Cere-bral palsy and other complications did not occur after 12 months of follow -up of the five cases.Conclusion The outer peripheral arteriovenous synchronous exchange transfusion therapy for neonatal severe hyperbilirubinemia can quickly reduce serum bilirubin,and has less impact on the body environment,it is an important and effective salvage treatment of neonatal hyperbilirubinemia,thereby reducing damage to the nervous system of bilirubin.

Neurobiology is a cross subject,in which"Language and Attention"is an impor-tant chapter as a hotspot involved with physiology,psychology,anatomy and biology.Inorder to im-prove the teaching efficiency,it is necessary to apply the techniques such as arranging the content logically,giving prominence to the emphases and breaking through the difficulty,using interactive teaching method and collocating the assistant method rationally. Through this way,it is easier for the students to get interested in this chapter and grasped the content.

Objective To explore the clinical effect of systemic nursing intervention on constipation after coronary heart disease. Methods 145 patients were randomly divided into intervention and control group. Patients in invention group were given systemic nursing intervention, including diet, exercise, health education and so on. The patients in control group were treated with cathartic.Results There was significant difference between intervention and control group in incidence of constipation or related complication(P<0.05). Conclusion Systemic nursing intervention is helpful to reduce constipation and prevent the related complication.

Objective To understand the epidemiological characteristics of hypertension in Chifeng.Methods 6 015 subjects aged over 15 years old were selected with stratified randomized sampling.The history of hypertension and social-economic status were investigated by face-to-face interview and blood pressure,body height,body weight and waistline were measured at the same time.Results The prevalence of hypertension in Chifeng was 28.5%.The age-adjusted prevalence was 19.09%.Thereinto,the prevalence of hypertension in urban area,rural area,pasturing area were 23.15%,19.85%,32.03%,respectively.The Hypertension prevalence in male was increased with age.The prevalence in male was higher than in female among people who lived in urban and pasturing area(P0.05).The prevalence were higher in illiterate person and semiliterate than people in other educational level(P

After the development of domestic embedded subject service and its domestic and foreign main models were described, following suggestions were put forward: thinking approach teaching contents and multiple elementary assessment system should be designed based on OBE theory with medical postgraduate general practical medical literature novelty assessment course as its starting point, excellent students should be trained as scientific information detectors by improving their information literacy and practical ability through small scale blended teaching, the professional bottleneck of librarians and talent team construction should be solved by cultivating subject service team for different subjects and strengthening the contacts between different subjects.

Objective To explore the clinical manifestations, pathogenic mechanisms and treatment of Mirizzi syndrome.Method 65 patients with Mirizzi syndrome were analysed retrospectively.Results According to Csendes typing, patients with Mirizzi syndrome included type Ⅰ in 18 patients(27 6%), type Ⅱ in 25 patients (38 4%), type Ⅲ in 13 patients(20 0%), type Ⅳin 9 patients(13 8%), all patients were healed by corresponding operation and perioperative management.Conclusions Good outcome of Mirizzi syndrome patients can be achieved by accurate diagnosis,exact operation and active perioperative management.

That sparkplugs and cognizances caution of medical morality base line is a realistic proposition that to spurn mammonism phenomenon filters medical service industry and enhances diathesis of medical affairs personnel.Medical service incited by mammonism phenomenon forms a menace to the medical base line,it is important inducement of medical action of getting out of line,and duties of medical risk and complaints of medical comsumer.Mammonism phenomenon form a nubbin quoted by medical morality base line and duties of medical risk.
