Objective To compare the safety and efficacy of different doses of intrathecal sufentanil for labor analgesia in parturients. Methods One-hundred ASA I or II nulliparous parturients at 39-40 weeks of gestation who requested labor analgesia were included in this randomized double-blinded study. They were all in active labor with a 2-3 cm cervical dilatation. The subarachnoid block was performed at L2, 3 . The patients were randomized to received intrathecal sufentanil 1,3,5,7,or 10 ?g. An epidural cather was then placed for patient-controlled epidural analgesia (PCEA) . The PCEA solution contained 0.1% ropivacaine and sufentanil 0.4 ?g ? kg-1 .The PCEA settings were as follows: background infusion 5 ml?h-1 , demand bolus 3 ml and lock-time interval 10min. Pain relief was assessed by VAS scores, oxytocin dose, maternal satisfaction, hemodynamics and side effects. Apgar scores of the new-borns were recorded. Results Demographic data including age, sex, body weight and baseline VAS were similar among the five dose groups. There were significant differences in the onset , duration and efficacy of analgesia among the five dose groups. Significantly more patients who received 10 ?g sufentanil reported nausea and vomiting and pruritus than those who received 1 or 3 fig sufentanil. There was no significant difference in Apgar scores among the 5 dose groups. Conclusion Intrathecal sufentanil combined with PECA is safe and effective for labor analgesia. Intrathecal sufentanil 3-5 ?g is the dose of choice for labor pain relief.

Objective To investigate the ultrasonic image characteristics of Zenker diverticulum(ZD).Methods The ultrasonographic features were summarized using the analysis confirmed by surgery pathology or X-ray imaging of the ZD in six eases.Results The diverticulum of Zenker located behind the thyroid gland in all the six cases,with five cases to the left and one to the right.The internal hyperechoic foci caused by air was found for all the six cases.The diverticulum wall appeared to be semicircular,narrow-band and acoustic halo low echo with an average thinckness of 0.53 mm.The Doppler sonogram of the six diverticulums showed no vascular signal.Conclusions The ZD had several unique characterisitics for identification by ultrasonic diagnosis,which included hyperechoic foci caused by air,internal changes of echo after drinking water and the special layered structure of the five-layer ZD wall.

microRNAs (miRNAs) are an extensive class of -22-nucleotide (nt) endogenous noncoding RNAs regulating life activities ofmetazoans through binding to 3'-untranslated regions (3'-UTRs) of their target genes. This work aimed to identify yan gene in the silkworm, reveal its expression profile and confirm if it is one target of bmo-miR-7 and, as such, have potential for contributing to better understanding of the molecular mechanisms involved in the metamorphosis of silkworm. Based on homolog searching and PCR amplification, we cloned the coding sequence (CDS) of Bmyan, which encodes 476 amino acid residues and contains SAM-PNT and ETs domains. Quantitative PCR (q-PCR), RT-PCR and microarray data revealed high expression of Bmyan in the head, body wall and ovary of day-3 fifth instar larval silkworm, low or no expression in other tissues. It was lowly expressed in the early larval stages, but highly expressed from late spinning to day 4 pupa. The 3'-UTR of Bmyan was obtained by rapid-amplification of cDNA ends (3'RACE) and predicted to contain two potential recognition sites of bmo-miR-7. The luciferase reporter vector containing the 3'-UTR of Bmyan was constructed and co-transfected into BmE cell line with the mimic of bmo-miR-7 and the decreased relative activity of luciferase showed that Bmyan is one target of bmo-miR-7. This work helps further functional analysis of bmo-miR-7 and Bmyan in the silkworm.

Objective To explore the effects of H 2 S on neuronal injuries induced by oxygen glucose deprivation /reoxygenation ( OGD/R) in cortical neurons .Methods For OGD, the primary cultured cortical neurons were incubated with glucose-free EBSS media for 4h in N2/CO2/O2 (93%/5%/2%) atmosphere.Thereafter, the media were replaced by Neurobasal/B27 culture media and the neurons were incubated for 12 h in a 5%CO2 incubator at 37℃.NaHS was used as a H2S donor and cell survival rate was determined by cell counting kit 8(CCk-8).[Ca2+]i was determined using fura-2/AM and fluorescence microscopic imaging systems .The release rate of lactate dehydrogenase ( LDH) was determined by lactate dehydrogenase assay kit , and cell damage was analyzed by staining of propidium iodide ( PI ) .Results After pretreated with 200, 300 and 600μmol/L sodium hydrosulfide ( NaHS) for 30min before OGD/R, the cell survival rate of neurons significantly increased (n=4).[Ca2+]I(n=5), LDH release rate (n=4) and cell damage percentage (n=6) in the neuron pretreated with 300 μM NaHS were significantly lower than those in ODG/R cells.Treatment with 10μmol/L calcium chelator BAPTA also reduced the LDH release rate and cell damage percentage induced by ODG /R in neurons . Conclusion The results indicate that H 2 S may inhibit the OGD/R induced damage in cortical neurons via reducing calcium overload of neurons .

Objective To identify the role of phosphatidylinositol-3-kinase(PI3K) in mediating necroptosis induced by tumor necrosis factor alpha (TNFα) and the involved mechanism.Methods Knockdown of p110α,receptor-interacting protein 1(RIP1) or both p110αand RIP1 was mediated by the specific short hairpin RNA (shRNA) lentivirus and verified by RT-PCR or Western blotting .In addition , Western blotting was used to detect phosphorylation of mixed lineage kinase domain-like protein(MLKL) and protein kinase B(AKT) or tetramerization of MLKL.Cell death was measured by micros-copy and flow cytometry.Results AKT phosphorylation and TNFα-induced necroptosis of L929 cells were suppressed by the inhibitors of PI3K or AKT, as well as p110αknockdown.Moreover, RIP1 knockdown did not inhibit L929 cell death induced by TNFαplus Z-VAD, but the RIP1-independent necroptosis was inhibited by p 110αknockdown.In addition, p110αknockdown suppressed MLKL phosphorylation and tetramerization induced by TNFαwith Z-VAD in L929 cells. Conclusion PI3K mediates necroptosis of L929 cells induced by TNFαby activating AKT and MLKL, respectively.

Objective The sirolimus-eluting stent (SES) has dramatically reduced the rate ofrestenosis in comparison to that with the bare-metal stent (BMS).This study aimed to evaluate the short-term efficacy and safety of Firebird stent implantation for patients with coronary heart disease (CHD). Methods From Apri12006 through July 2007, 155 patients (mean age 58.93～10.27 years) with CHD were implanted with Firebird stent or Cypher select stent at Daxing Hospital. Patients were followed up for one year. All-cause mortality, major adverse cardiac events (MACE, including cardiac death, myocardial infarction, recurrence of angina pectoris, heart failure, revascularization, and adverse arrhythmia) and stent thrombosis were compared between the 2 groups. Results Of the 155 consecutive patients, 147 patients were revascularized completely. Of these patients, 48 (with 59 lesions) were treated with Firebird stent, 59 patients (with 75 lesions) with Cypher select stent. The demographic characteristics were similar in the 2 groups. All the angiographic and procedural results were not significantly different between the 2 groups. All-cause mortality, myocardial infarction, recurrence of angina pectoris, MACE and stent thrombosis were almost identical between the 2 groups before discharge, at 6 months and at one year .Conclusion The short-term efficacy and safety of Firebird stent are similar to that of the cypher select stent for the treatment of patients with CHD.
