OBJECTIVE: To establish an HPLC method for simultaneous determination of peoniflorin,calycosin and ferulic acid in Kangmin granules.METHODS: The separation was performed on a Kromasil C18 column (250 mm?4.6 mm,5 ?m),and the mobile phase consisted of methanol-acetonitrile-0.4% phosphonic acid (20 ∶ 10 ∶ 70) with flow rate of 1.0 mL?min-1.The detection was performed at wavelength of 254 nm.Column temperature was room temperature and the injection volume was 10 ?L.RESULTS: The linear ranges of peoniflorin,calycosin and ferulic acid were 180～3 600 ?g?mL-1(r=0.999 2),4.6～92.0 ?g?mL-1(r=0.999 1) and 8.0～160.0 ?g?mL-1(r=0.999 4),respectively.The average recoveries were 98.3%(RSD=1.8%,n=9),99.0% (RSD=2.0%,n=9) and 100.5%(RSD=1.1%,n=9),respectively.CONCLUSION: The method is simple,accurate,sensitive and reproducible for the quality control of Kangmin granules.

BACKGROUND: Multiple sclerosis(MS) is a chronic autoimmune disease induced by the interaction between genetic and environmental factors. Its pathogen and the mechanism of the relapse and remission m the course of the disease are still unknown. Most of the MS research centers are looking for the pathogenic polypeptide epitope in proteolipid protein(PLP), myelin sheath basic protein (MBP) and oligodendrocyte glycoprotein (MOG) OBJECTIVE: To compare the proliferation of T cell lines(TCL) in MS induced by myelin sheath and delipidated myelin sheath towards 11 components of myelin sheath to mainly search the possible pathogenic polypeptide epitope in PLP, and investigate the possible effects of abnormal dcgrease in myelin sheath.DESIGN: A case-controlled trial.SETTING: Department of neurology in a hospital of a university.PARTICIPANTS: Mononuclear cells(MNC) of 16 MS cases(clinical relapsing-remitting type, patients did not receive any immunosuppresant for at least 3 months when their peripheral blood samples were taken) and 12 HLA-DR15 healthy volunteers were furnished by Dr. Trotter JL of MS Research Center of Washington University from the cell database.INTERVENTIONS: MS-TCL and normal TCL were induced twice by stimulation with myelin sheath and delipidated myelin sheath in vitro by cell culture in vitro. TCL proliferation was tested by 11 antigens including PLP,MBP, M87-106, P30-49, P40-60, P89-106, P95-117, P117-137,P139-151, P178-191, and P185-206.MAIN OUTCOME MEASURES: Difference of scintillation counting in every minute of every well, and the stimulative index of each well were calculated, and the mean wells with positive proliferation of TCL towards each antigen were confirmed as well.RESULTS: The general specific proliferation towards myelin sheath antigens was bigger in MS group than control group 5.49 ±5.31 to 3.10 ± 3. 17, and delipidated myelin sheath-induced TCL was bigger than myelin sheath-induced one 5. 49 ± 5.31 to 3.41 ± 4. 83 . Delipidated myelin sheath significantly changed the immune responses of MS group,especially the changes of responses towards P30-49, P40-60, P89-106,P117-137, P139-161, and P185-206 were significant compared with that the control group only responded to two polypeptides, which indicated that the antigen epitope of MBP, PLP, M87-106, P95-117, P40-60, and P185-206 might have significance in the triggering of MS autoimmune responses.CONCLUSION: TCL induced by MS myelin sheath has different proliferation towards antigen components of myelin sheath from control group. Delipidated myelin sheath significantly increases TCL proliferation in MS group, which suggests that if MS patients developed abnormal degrease in myelin sheath, TCL would produce autoimmune response towards self-myelin sheath, MBP, PLP and its polypeptide segments all can trigger MS or aggravate the state of the illness. Our finding supports the hypothesis of MS autoimmune pathogenic mechanism.

Objective To study the application value of serum umbilical cord blood bilirubin and hemolysis three test in the prediction of neonatal hyperbilirubinemia.Methods 1 200 cases of healthy newborn were selected,whose mothers were type O blood and fathers were not type O blood.According to the situation of maternal and infant blood type,they were divided into the same maternal and child blood type group with 539 cases and different blood type group with 661 cases;According to the umbilical cord blood bilirubin concentration range was divided into five groups,and analyzed umbilical cord blood bilirubin and hemolysis three test in the prediction of neonatal hyperbilirubinemia.Results (1) The concentrations of umbilical cord blood bilirubin,the incidence of ABO-HDN,the incidence of hyperbilirubinemia in the maternal-fetal blood(O-A/B) group were (38.1 ± 10.3) μmol/L,47.35％,26.02％,respectively,which were all significantly higher than (33.4 ± 7.9)μmol/L,15.21％,14.66％ in the maternal blood type (O-O) group (t =5.8,x2 =120.7,x2 =20.1,all P =0.000) ; (2) When the concentrations of umbilical cord blood bilirubin was higher,the incidence of hyperbilirubinemia was higher,but the sensitivity and the specificity both were bad; (3) According to the result of hemolysis three to predict the neonatal hyperbilirubinemia,when the concentrations of umbilical cord blood bilirubin was less than 21μmol/L or more than 55μmol/L,the positive predictive value and the specificity both were 100.00％,and the sensitivity was not low(75.00％ and 86.96％).Conclusion Detection of umbilical cord blood bilirubin and hemolysis three test in the maternal-fetal blood group incompatibility could predict early hyperbilirubinemia of newborn,which had certain clinically practical value.

Objective To observe the clinical effect of xerophthalmia of meibomian glands dysfunction treated with meibomian glands massage and tobramycin dexamethasone in the northeast area.Methods The clinical data of 403 patients (767 eyes) with xerophthalmia of meibomian glands dysfunction in the northeast area in January to November 2013 were analyzed retrospectively.The patients were divided into 3 groups.Patients of treatment goup 1 were combined modality therapy by meibomian glands massage and tobramycin dexamethasone and artificial tears (carbomer eye ophthalmic gel).Patients of treatment goup 2 were treated with tobramycin dexamethasone and artificial tears.Patients of control group were only used by artificial tears.Tear film break-uptime (BUT),tear secretion test (Schirmer Ⅱ),corneal staining score and symptom score were measured before treatment and after treatment for 1,3 months.Results There was no significant difference in the subjective symptoms,BUT,Schirmer Ⅱ,corneal staining score before treatment among three groups (P ＞ 0.05).Compared with that before treatment,the subjective symptoms,BUT,Schirmer Ⅱ,corneal staining score after treatment for 1 month was improved in treatment group 1 and treatment group 2 (P ＜ 0.01),but there was no significant difference in control group (P ＞ 0.05).After treatment for 3 months,the effective power in treatment group 1 [87.1％(122/140)] and treatment group 2 [60.8％(79/130)] was higher than that in control group [48.9％(65/133)],and there was significant difference (P ＜ 0.05).And there was significant difference between treatment group 1 and treatment group 2 (P ＜ 0.05).Conclusions Xerophthalmia of meibomian glands dysfunction in the northeast area due to speciality in the geographical environment and food habits.Combined modality therapy (applied heating,meibomian glands massage and tobradex) can provide a new direction of xerophthalmia of meibomian glands dysfunction,retrieve in the lipids component of the tear film and eliminate the inflammation.But,dependence of the out-patients are very important in the therapeutic process.

Objective · To compare the prevalence of tobacco advertisement before and after implementation of the new edition of Advertising Law of the People's Republic of China and evaluate the effects of implementation of the new Advertising Law. Methods · Tobacco sales places, public places, and streets in Shanghai were randomly selected to observe tobacco advertisement and complete the survey. The survey was carried out in 10 districts of Shanghai in June 2015 with 10 tobacco sales places selected in each district, and in 4 districts of Shanghai in June 2016 with 25 tobacco sales places selected in each district. Sales places included convenient stores, tobacco stores, supermarkets, and kiosks. In addition, public transport waiting points, public transport vehicles, hospitals, shopping centers, restaurants, bars, and Internet cafes were selected into survey in 2016. Results · In 2016, the proportion of tobacco sales places having tobacco advertisement was lower than that in 2015, but the proportion of tobacco promotion behaviors was higher. In 2016, 128 public places and streets were investigated and only 1 had outdoor tobacco advertisement. Conclusion · The new edition of Advertising Law has significant effect on controlling tobacco advertisement, but tobacco sales places still have tobacco advertisement with various disguised promotion forms. Tobacco sales places have diversified business styles and minors often enter these places. It is recommended that a clear definition of disguised forms of tobacco advertisement should be made, tobacco advertisement at tobacco sales places needs to be supervised, the release of tobacco advertisement should be strictly reviewed, and existing tobacco advertisement should be severely punished, so as to prevent minors from exposing to tobacco advertisement and information luring smoking.

Objective To investigate the effects of a single exposure or multiple exposures with equivalent total duration of exposure to sevoflurane on the histological morphology and neurons ultrastructure changes in neonatal rats hippocampus CA1.Methods A total of 45 male Sprague-Dawley rats on postnatal day 7,weighing 14-18 g,were randomly divided into three groups (n=15 each): Control group (group C),single exposure to sevoflurane group (group SS),multiple exposures to sevoflurane group (group TS).In group SS,the rats inhaled 3% sevoflurane for 6 h on postnatal day 7.In group TS,the rats inhaled 3% sevoflurane for 2 h on postnatal day 7,8 and 9.In group C,the rats inhaled 60% oxygen on the corresponding day age.Rats were sacrificed and brain were seperated on postnatal day 14.CA1 pyramidal neurons pathological morphology and quantity changes were observed by Hematoxylin-Eosin (HE) and Nissl staining.In the meantime,transmission electron microscopy was used for observing neurons ultrastructure and measuring the thickness of the postsynaptic density and the length of the postsynaptic active area.Results Nissl staining and HE indicated that multiple exposures and a single 6 h exposure to sevoflurane resulted in severer neurons loss and sparse arrangement relative to group C (P<0.05),Multiple exposures to sevoflurane resulted in greater neurons loss compared with a single 6-h exposure (P<0.05).Transmission electron microscope indicated that damage of CA1 neuronal subcellular organelle induced by multiple exposures and a single 6 h exposure was severer compared with group C.Both multiple exposures and a single exposure lead to decreased thickness of the postsynaptic density and shorter length of the postsynaptic active area (P<0.05).Multiple exposures to sevoflurane caused greater damaged than a single exposure (P<0.05).Conclusion Both a single and multiple exposure to sevoflurane induced CA1 neurons loss and ultrastructure changes in neonatal rats.Compared with a single exposure,multiple exposures to sevoflurane resulted in greater neurons morphology injury.
