Objective To evaluate the efficacy of locally administered dexamethasone for prevention of low back pain after labor epidural analgesia.Methods Two hundred nulliparous parturients who required labor epidural analgesia,of ASA physical status Ⅰ or Ⅱ,were randomly divided into 2 groups (n =100 each) using a random number table:control group (group C) and dexamethasone group (group D)).In group D,lidocaine 4 ml and dexamethasone 1 ml (5 mg) were injected around the puncture site.In group C,lidocaine 4 ml and normal saline 1 ml were injected around the puncture site.Epidural puncture was performed after local administration.According to the results of epidural puncture,each group was further divided into two subgroups:single puncture group (Cs subgroup,Ds subgroup) and repetitive puncture group (Cr subgroup,Dr subgroup).The patients were followed up for 72 h,and the development of low back pain was recorded.Results Compared to group C,the incidence of low back pain was significantly decreased,and pain was reduced in group D.The incidence of low back pain was significantly lower in Ds group than in Cs group,and in Dr group than in Cr group.Conclusion Locally administered dexamethasone 5 mg is helpful in reducing low back pain after labor epidural anesthesia.

OBJECTIVETo analyze the rules for acupoint selection of acupuncture and moxibustion in domestic clinical treatment of perimenopausal syndrome based on data mining technology in modern times.

METHODSThe relevant literature were retrieved from Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI) and Wanfang database on this disease treated with clinical acupuncture and moxibustion in China from 1978 to 2013. The database of acupuncture-moxibustion prescription was set up. The relevant regulations of data mining technology were used to analyze the rules for acupoint selection.

RESULTSTotally, 211 papers, 254 acupuncture-moxibustion prescriptions and 130 acupoints were included. The total frequency of acupoints application was 2193 times, with 14 meridians involved. The utilization of the acupoints in the lower limbs and on the back were 33.0% (723/2193) and 23.8% (521/2193) and those of yin and yang meridians were 51.8% (1136/2193) and 44.0% (965/2193), respectively. The utilization of the specific acupoints accounted for 88.7% (1946/2193).

CONCLUSIONIn clinical treatment of perimenopausal syndrome with acupuncture and moxibustion in modern times, the acupoint selection from involved meridians is the basis, associated with multiple methods of acupoint combination; yin and yang meridians are equally important and the specific acupoints are considered particularly critical in application.

Objective To observe the effect of fast acupuncture at Zusanli(ST36) on the recovery of gastrointestinal function after abdominal non-gastrointestinal surgery. Methods In this randomised placebo-controlled single-blind clinical trial, patients received abdominal non-gastrointestinal surgery were assigned to a treatment group and a control group. The treatment group received fast acupuncture and the control group received superficial conciliative acupuncture. The acupuncture was taken at both sides of Zusanli (ST36) for 1 minute respectively during 7-8 a.m. and 7-8 p.m..We began from the first postoperative day and stopped when the patients got initial postoperative flatus or stool, or at the end of the fifth postoperative day. Results 37 controlled patients were assigned to the treatment group (18 patients) and the control group (19 patients) randomly. There were no differences on general information between the two groups. The treatment group had stronger feeling than the control group on the comparison of the acupuncture sensation level (5.7 ± 3.0 vs. 2.7 ± 2.2;t=-3.471, P=0.001). For the treatment group, the initial postoperative flatus or stool time is 19 hours earlier than the control group (65.9 ± 18.1 h vs. 85.0 ± 24.5 h; t=2.682, P=0.011). And the treatment group patients’ postoperative abdominal distension is lesser than the control group (P=0.006). Conclusion Fast acupuncture at Zusanli(ST36) can promote the recovery of gastrointestinal function after abdominal non-gastrointestinal surgery, and can also lighten the patients’ postoperative abdominal distension.

According to the super-position principle of the reinforcement of biological activities, a series of novel E-substituted 2, 3-diaryl propenoic acyloxy phosphonate derivatives were designed and synthesized. And the structures of the target compounds were confirmed by IR, 1H NMR, 13C NMR and elemental analysis. Furthermore, the cytotoxicities of all compounds on A-549, SGC-7901 and EC-109 in vitro were evaluated by MTT assay, and some of them showed good antitumor activity. Among the active compounds, especially, the IC50 value of compound 3e was (12.7 ± 1.9) μmol x L(-1) against A-549 cells, similar to cisplatin [IC50 = (8.0 ± 1.5) μmol x L(-1)], compounds 3g and 3k had better inhibition effect on EC-109 cells growth, with the IC50 values of (9.5 ± 1.8) μmol x L(-1) and (11.5 ± 0.9) μmol x L(-1) respectively, and compounds 3i and 3k exhibited good cytotoxic property on A-549, SGC-7901 and EC-109, which were worth further investigation.

AIMTo investigate the relation between Glu-R and the protective effect of hypothermia on oxygen and glucose deprivation (OGD) injury in hippocampal slices of rat.

METHODS(1) We had established OGD injury model in rat hippocampal slices. The changes of orthodromic population spike(OPS) during OGD and after administration of hypothermia (32 degrees C, 25 degrees C) were observed. (2) We had established Glu excitatory toxicity injury model in rat hippocampal slices. The changes of OPS after exposure to Glu and the effect of hypothermia (32 degrees C, 25 degrees C) against the Glu excitatory toxicity injury were observed. The non-NMDA receptor-mediated excitatory postsynaptic potentials (EPSP) in the CA1 area were recorded via adding the GABA-R specific agonists bicuculline (BMI) and NMDAR agonists D-(-)-2-Amino-5-phosphonopentanoic Acid (AP5) in normal artificial cerebrospinal fluid (nACSF), the NMDA receptor-mediated EPSP were recorded via adding the BMI and non-NMDA-R agonists 6,7-Dinitroquinoxaline-2, 3(1H,4H)-dione(CNQX) in nACSF. The variety of the changes of OPS during OGD14min in nACSF groups and added BMI compounded AP5 or BMI compounded CNQX ACSF groups were observed after administration of 25 degrees C hypothermia 28 min. (3) The changes of ultrastructure of CA1 area after OGD 1 h and the effect of hypothermia (25 degrees C) on it were observed.

RESULTS(1) OPS reduced and abolished quickly during OGD14min, and the recovery amplitude of OPS was very low after reoxygenation/glucose 1 h. While the time of OPS abolishing significantly elongated and the recovery of OPS was higher in hypothermia (32 degrees, 25 degrees C) groups. The effect in groups 25 degrees C was more significant than those in groups 32 degrees C. (2) In control groups, Glu (2 mmol/L, 14 min) decreased the amplitude of OPS, after the end of Glu exposure the recovery amplitude of OPS was very low. After administration of hypothermia (32 degrees C, 25 degrees C), the recovery amplitude and rate of OPS were significantly higher than those in the control groups, while the antagonism on Glu excitatory toxicity injury in H 25 degrees C was more significant than those in H 32 degrees C. The changes of OPS during OGD 14 min were no distinct difference in nACSF groups and added BMI (50 micromol/L) compounded AP5(20 micromol/L) or BMI (50 micromol/L) compounded CNQX (100 micromol/L) ACSF groups. The protection of hypothermia (25 degrees C) could not be cancelled by added AP5 compounded BMI or BMI compounded CNQX in nACSF. (3) After OGD (14 min) 1 h, the nuclear membrane of pyramidal cells in CA1 area was irregular, nucleus were homogenized, the organelle in the cytoplasm was degenerate, even more to necrosis or loss, mitochondrion swelled, ridge was vacuoles. In H 25 degrees C the nuclear membrane was regular, mitochondrion swelled only lightly. Small chromatin gathered to edge.

CONCLUSIONHypothermia shows the protective effects of against OGD injury in hippocampal slices. The mechanism is related to the antagonism of Glu excitor toxicity and maintenance the ATP level in cells, and the antagonism perhaps is mediated by NMDA-R and non-NMDA-R.

Huperzine A is a potent,reversible,and blood-brain barrier permeable acetylcholinesterase irhibitor.The aim of this study was to compare the pharmacokinetics,tolerability,and bioavailability of two formulations with the established reference formulation of huperzine A in a fasting,healthy Chinese male population.This was a randomized,single-dose,3-period,6-sequence crossover study.The plasma concentrations of huperzine A were determined by liquid chromatography tandem mass spectrometry.Tolerability was assessed based on subject interview,vital sign monitoring,physical examination,and routine blood and urine tests.The mean (SD) pharmacokinetic parameters of the reference drug were Cmax,1.550 (0.528) ng/mL;t1/2,12.092 (1.898) h;AUC0-72h,17.550 (3.794) ng.h/mL.Those of the test formulation A and test formulation B were Cmax,1.412 (0.467),1.521 (0.608) ng/mL;t1/2,12.073 (2.068),12.271 (1.678) h;AUC0-72h,15.286 (3.434) ng.h/mL,15.673 (3.586) ng.h/mL.The 90％ confidence intervals for the AUC0-72h and Cmax were between 0.80 and 1.25.No adverse events were reported by the subjects or found with results of clinical laboratory test.The test and reference products met the regulatory criteria for bioequivalence in these fasting,healthy Chinese male volunteers.All three formulations appeared to be well tolerated.

Objective To explore the impact of chronic complications of type 2 diabetic mellitus (T2DM)on quality of life(QOL)among T2DM outpatients in urban China.Methods A cross.Sectional study was carried Out in 1524 T2DM outpatients recruited from 15 hospitals in 4 major cities of China.Questionnaire interviews were used to collect data on general characters and complications of T2DM.SF-36 questionnaire(version 1)was used and self-completed by patients under the help from interviewers for those having difficulties in reading.T test,one-way ANOVA and generalized linear model were used to explore the association between complications of T2DM and quality of life.Results Complication Was a significant predictor leading to poorer SF-36 subscale scores(decreased by 4.68-16.06 scores)and two summary scores (PCS,MCS).The scores of role-physical subscale(decreased by 22.45％)and role-emotionsl subscale(decreased by 16.28％)decreased much more than the other subscales in patients with complication.Overall,QOI Was reduced by 11.02％in patients with complication.The QoL had a gradual decrease with the increasing number of complications.The average scores descended from 2.82 to 10.33 in the eight subscales with the increase of one complication.Conclusion Having complication or multiple complications seemed to be predietors of poor QOL among T2DM outpatients.

OBJECTIVETo evaluate the clinical effect of a 10-day sequential therapy which was made up of omeprazole, clarithromycin, amoxicillin-clavulanate and metronidazole for the eradication of Helicobacter pylori (Hp) infection in children.

METHODA total of 214 children with abdominal pain, who were confirmed to have Hp infection through endoscopy, biopsy, and Hp culture. The 214 cases were randomly divided into four groups. A 10-day sequential therapy group accepted omeprazole 0.8 - 1.0 mg/(kg·d) plus amoxicillin-clavulanate 50 mg/(kg·d) for five days and omeprazole 0.8 - 1.0 mg/(kg·d), clarithromycin 20 mg/(kg·d) and metronidazole 20 mg/(kg·d) for the remaining five days. The 7-day triple therapy group, 10-day triple therapy group and 14-day triple therapy group received omeprazole 0.8 - 1.0 mg/(kg·d), amoxicillin-clavulanate 50 mg/(kg·d) and clarithromycin 20 mg/(kg·d) for 7 days,10 days,14 days, respectively. All drugs were given twice daily. All these patients received (13)C urea breath test ((13)C-UBT) four weeks after the treatment.

RESULTFinally, 199 patients were followed up, and the total rate of loss to follow-up was 7.0% (15/214). Hp eradication rate was 85.2% and 90.2% in the 10-day sequential therapy group on intention to treat (ITT) and per protocol (PP) analyses, 66.0% and 71.4% in the 7-day triple therapy group on ITT and PP analyses; 60.0% and 67.3% in 10-day triple therapy group on ITT and PP analyses, and 78.8% and 82.0% in patients who received the 10-day sequential regimen on ITT and PP analyses, respectively. By ITT analysis, there was significantly difference between the 10-day sequential therapy group and 7-day or 10-day triple therapy group (P < 0.05), while no significant difference was found between the 10-day sequential therapy group and 14-day triple therapy group (P > 0.05). The results of the ITT analysis and the PP analysis were the same. The four groups had neither significant difference in abdominal pain relief (P > 0.05) nor in incidence of adverse reactions (P > 0.05).

CONCLUSIONThe 10-day sequential regimen was significantly more effective than both 7-day triple regimen and 10-day triple regimen, while had the same eradication rate compared with the 14-day sequential therapy. But 10-day triple regimen to eradicate Hp infection in children had the advantages such as short course of treatment and better compliance.

OBJECTIVETo assess the value of fluorescence in situ hybridization (FISH) in the diagnosis of common chromosome number aberration in spontaneously aborted fetuses.

METHODA total of 100 spontaneously aborted fetuses were analyzed by G-banding and by FISH to test chromosome number aberration mainly for chromosomes 13, 18, 21, X and Y, and the results of FISH test was assessed according to those by G-banding test.

RESULTSFISH results were well consistent with those by G-banding test. FISH test identified trisomy in 32 samples and polyploidy in 7 samples. Two samples with cell culture failure were found to have trisomy 16 by FISH. Discrepancies in the results between the two tests occurred in 3 samples, but the results of FISH were verified by other methods. Kappa test between FISH technology and G-banding showed a good consistency between FISH and karyotyping (P<0.05).

CONCLUSIONFISH is an effective and rapid method for detecting chromosome number aberration in spontaneously aborted fetuses, and the combination of FISH and karyotyping provides more reliable diagnostic evidence.
