Objective To evaluate the effect of multiple-mode analgesia consists of epidural administration of lidocaine,parecoxib intravenously and patient-controlled epidural analgesia (PCEA) on patients after thoracic surgeries. Methods Total 90 patients treated with thoracic surgeries were allocated into 3 groups by random digits table,each with 30 cases. Patients accepted 1% lidocaine 5 ml epidurally 5 min before incision in group A and B,and 5 ml saline as control in group C. When chest closing parecoxib 40 mg were given in group A,and 2 ml saline as control in group B and C. All the patients were given PCEA. Postoperative hemodynamics,dosage of remifentanil and analgetics of PCEA within 48 h, visual analogue scale (VAS) of pain, rescue of pethidine, duration for first pain calling,and satisfactory scores of patients, doctors and nurses were recorded. Results Dosage of remifentanil was lower [(0.72±0.26), (0.84±1.20) μg／(kg·min)], and duration for first pain calling was longer[(35.00±2.78),(12.09±6.27) min] in group A and B than that in group C significantly[(1.80±0.84) μ,g／(kg·min) and (5.95±3.65) min](P<0.05). Analgetics of PCEA with in 48 h in group A was lower than that in group B which was lower than that in group C[(180.40±20.48), (192.54±40.15), (220.26±36.78) ml](P< 0.05). No difference was found on VAS of pain and hemodynamics among three groups when patients were kept immobilized, but VAS of pain in group A and B was lower than that in group C when patients kept moving. Satisfactory scores of patients,doctors and nurses in group A were higher. Conclusion Epidural administration of 1% lidocaine combined with intravenous paiecoxib 40 mg and PCEA an offer satisfactory postoperative analgesia for patients after elective thoracic surgeries.

Objective To explore the effect of a novel colloidal gold immunochromatographic test strip for detection of group B streptococci (GBS).Methods A total of 202 cases of swab of vagina or neck of uterus were collected,and they were detec-ted by novel strip and control strip to evaluate their clinical applications.Results Sensitivity of novel strip was about 105 CFU/ml and the detection time was about 5 to 8 minutes,and it showed better sensitivity and shorter detection time com-pared with control strip.In the 202 cases of clinical samples,the detection results of 197 cases were in consistent with the control strip,however,the detection results of 5 cases were not in consistent.The positive coincidence rate and negative coin-cidence rate were 97.5% and 97.54% respectively,and the total coincidence rate and Kappa value were 97.52% and 0.948 respectively.The consistency test showed no significant difference between this strip and control strip.Conclusion This method was a effective technology for diagnosing of infection caused by GBS,and had high value in clinical application.

The anaerobic granular sludge from an Internal Circulation (IC) reactor of a paper mill wastewater treatment plant were seeded in an Anammox upflow anaerobic sludge blanket reactor. After 185 days operation, the reactor was finally started up by increasing the influent ammonium and nitrite concentrations to 224 mg/L and 255 mg/L, respectively, with volumetric nitrogen removal rate increasing to 3.76 kg/(m3·d). The physicochemical characteristics of the cultivated Anammox granules were observed by scanning electron microscope, transmission electron microscope and Fourier Transform infrared spectroscopy (FTIR). Results suggested that during the start-up course, the granular sludge initially disintegrated and then re-aggregated. FTIR spectra results revealed that the Anammox granular sludge contained abundant functional groups, indicating that it may also possess good adsorption properties. The ecological structure of the granular sludge, analyzed by the metagenomic sequencing methods, suggested that the relative abundance of the dominant bacterial community in the seeding sludge, i.e., Proteobacteria, Firmicutes, Bacteroidetes, significantly reduced, while Planctomycetes which contains anaerobic ammonium oxidation bacteria remarkably increased from 1.59% to 23.24% in the Anammox granules.

AIM:To observe the effect of B-HT933, a selective α2-adrenoceptor agonist, on lipopolysaccha-ride ( LPS )-induced TNF-αproduction in neonatal rat cardiomyocytes and to explore the underlying mechanisms . METHODS:The neonatal rat cardiomyocytes were cultured .The localization of α2A-adrenoceptor in the cardiomyocytes was examined by immunofluorescence staining .The cardiomyocytes were exposed to LPS or/and B-HT933 for different time.The level of TNF-αin the supernatants and the mRNA expression of TNF-αwere detected by ELISA and real-time PCR, respectively.In addition, LPS-associated signal molecules in the cardiomyocytes were also examined by Western blotting.RESULTS: Immunofluorescence staining showed that α2A-adrenoceptors were localized in the cardiomyocytes . LPS stimulated TNF-αproduction in the cardiomyocytes in a dose and time-dependent manner .B-HT933 pretreatment sig-nificantly inhibited the expression of TNF-αat mRNA and protein levels in LPS-treated cardiomyocytes .Furthermore, LPS exposure induced IκBαand p38 phosphorylation in cardiomyocytes and only IκBαphosphorylation was prevented by B-HT933 treatment.CONCLUSION:α2A-adrenoceptors are present in neonatal rat cardiomyocytes and its agonist B -HT933 inhibits LPS-induced TNF-αproduction in cardiomyocytes via suppressing IκBαphosphorylation .

OBJECTIVETo analyze the value of ovarian reserve markers for predicting ovarian response in women undergoing in vitro fertilization-embryo transfer.

METHODSAccording to the ovarian response, 331 patients undergoing oocyte retrieval cycles were divided into of normal, poor, and high response groups. Serum anti-Mvllerian hormone (AMH) was determined using AMH ELISA kit on day 3 of the menstrual cycle, antral follicle count (AFC) was measured using vaginal ultrasound, and basal serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E(2)) levels were detected using chemiluminescence method.

RESULTSSerum AMH and FSH levels, FSH/LH ratio, AFC, and the patients age, but not the basal E(2) level (P>0.05), were correlated with the number of oocytes collected (×1000/ampules of Gn) (P<0.001). AFC and serum AMH were the strongest single predictors for low ovarian response, with the areas under curve (AUC) of 0.855 (0.787-0.924) and 0.832 (0.764-0.900) (P<0.05), and cutoff values of ≤9 and ≤1.88 ng/ml, respectively. AFC was the strongest single predictor for high ovarian response, with an AUC of 0.787 (0.728-0.847) and the cutoff value of ≥15. Logistic regression model found that the combination of AFC, serum AMH and FSH improved the predictive power for poor ovarian response, but not for high ovarian response.

CONCLUSIONAFC, serum AMH, FSH, FSH/LH, and age are all predictors of ovarian response, among which AFC is the strongest single predictor. A multivariable model can improve the predictive power for low ovarian response but not for high ovarian response.
