Objective To evaluate the agreement between colposcopic diagnosis with 2011 colposcopic terminology of the International Federation for Cervical Pathology and Colposcopy (IFCPC) and cervical pathology in cervical lesions. Methods A retrospective cohort study was performed, which included 376 patients who underwent colposcopy with 2011 international terminology of colposcopy at Obstetrics and Gynecology Hospital of Fudan University from September 2014 to November 2014. With conization or cervical biopsy pathology as the gold standard, the agreement between colposcopic diagnosis and pathologic diagnosis was calculated and correlations between variables were analyzed. Results With 2011 international terminology of colposcopy, agreement of colposcopic diagnosis and cervical pathology was 60.9%(229/376)perfectly matched, and the strength of agreement with weighted Kappa statistic was 0.401 (P<0.01), and agreement within one grade was 97.6%(367/376), which were improved compared with traditional methods. Colposcopic diagnosis were 19.9%(75/376) overestimated and 19.1%(72/376) underestimated. There were no significant difference between agreements in various grade lesions (χ2=1.996, P=0.573). Positive predictive value of high grade colposcopy or more was 84.4%, the negative predictive value of low grade colposcopy or less was 88.8%, whereas false positives were 3.5%and false negatives were 39.3%. A linear trend among three types of transformation zone and patient ages was found (χ2=45.910, P<0.01), whereas lesion sizes were not linearly correlated with lesion degrees (χ2=0.690, P=0.406). In grade 1, grade 2 and nonspecific findings, thin acetowhite epithelium, dense acetowhite epithelium and Lugol′s non-staining were most frequent, the Youden indexes of each were 0.170, 0.373 and 0.145, 0.069 respectively. Positive predictive value of some other findings (such as fine mosaic) and two new signs (inner border sign and ridge sign) were 100.0%. There were no significant difference between agreements in examiners with different levels of experience (χ2=1.197,P=0.550). Conclusions Compared to traditional methods (such as Reid index), 2011 international terminology of colposcopy could improve the agreement between colposcopic diagnosis and pathologic diagnosis, without significant differences by the severity of lesion and the level of examiners′experience. Common findings were classified reasonably, and some signs were highly reliable, which is important for guiding biopsy. However, the reproducibility of transformation zone types and the implication of lesion size need to be further discussed.

A method was proposed for the separation and determination of paraffin waxes in food by HPLC-evaporative light scattering detection (ELSD). A normal-phase column was used to separate nonparaffinic and paraffinic materials without resolving the latter into individual components. The t-test method was adopted for the evaluation of mean difference between response factors of n-alkanes in paraffin waxes on ELSD detector. No mean difference was obtained between response factors, which can be used for quantitative determination of paraffin waxes in food. The determination results obtained by HPLC-ELSD were compared with those by GC-MS. The linear range for the determination of paraffin waxes was in the range from 10 to 500 mg/L with a correlation coefficient of 0.9988, and the limit of detection was 1.0 mg/L. With the spiking level of 10, 50 and 100 mg/kg, the recovery ranged from 84.6% to 105.4% and the relative standard deviation ranging from 5.4% to 7.2%. The proposed method is simple, fast and sensitive.

AIM To aim at investigating the function of Kaixin Jieyu Pills (Ginseng Radix et Rhizoma,Bupleuri Radix,Morindae officinalis Radix,etc.) to vascular depression and their mechanism of action.METHODS A vascular depression model of rat was established by chronic unpredictable mild stress and separation after ligation of the bilateral common carotid arteries.The rats were treated with Kaixin Jieyu Pills and fluoxetine hydrochloride (FLU) for 28 days,respectively.The sucrose preference test and open-field test were performed.Cerebral perfusion was investigated with a Perfusion Speckle Imager.The monoamines including serotonin,dopamine and noradrenaline,and brain-derived neurotrophic factor (BDNF) were determined with ELISA and Western bolt,respectively.RESULTS Kaixin Jieyu Pills significantly increased sucrose preference,moving distance and cortical blood flow.Kaixin Jieyu Pills could upregulate,to different extents,the expressions of monoamines,including serotonin,noradrenaline and dopamine,and BDNF.Kaixin Jieyu Pills had a function similar to FLU in behavior,upregulating monoamines and BDNF,but it is superior to FLU in cortical blood flow.CONCLUSION Kaixin Jieyu Pills has the advantage of reducing the depression-like behavior and improving cerebral hypoperfusion,which might be mediated by the upregulation of the serotonin,noradrenaline and BDNF.

Objective To investigate the pharmacodynamics of different local anesthetics administered intrathecally for elderly patients undergoing transurethral resection of the prostate (TURP). Methods Ninety ASA Ⅰ - Ⅲ elderly patients, aged 69-82 yr, with body mass index less than 30 kg/m2 , undergoing TURP under combined spinal-epidural anesthesia, were randomly divided into 3 groups ( n = 30 each): levobupivacaine group (group L), ropivacaine group (group R) and bupivacaine group (group B). Group L, R and B received intrathecai (IT) 0.5 % levobupivacaine, 0.5 % ropivacaine and 0.5 % bupivacaine respectively. The initial dose was 7,10 and 6 mg in group L, R and B respectively. The ratio of two successive doses was 0.9. If the upper sensory block reached T10 within the 20 min after IT injection, the IT analgesia was considered to be effective. The median effective dose (EDs0) and 95 % confidence interval (95 % CI) were calculated by Dixon. Results The ED50 and 95% CI of levobupivacaine, ropivacaine and bupivacaine were 6.781 (95% CI 6.561-7.024) mg, 9.135 (95%CI8.670-9.616) mg and 5.170 (95% CI 5.012-5.333) ng respectively. The relative potency ratio between levobupivacaine, ropivacaine and bupivacaine is 0.76∶0.57∶1.00. ConclusionThe relative potency ratio be tween levobupivacaine, ropivacaine and bupivacaine is 0.76∶0.57∶1.00.

Previous studies have indicated that ERp44 inhibits inositol 1,4,5-trisphosphate (IP(3))-induced Ca(2+) release (IICR) via IP(3)R(1), but the mechanism remains largely unexplored. Using extracellular ATP to induce intracellular calcium transient as an IICR model, Ca(2+) image, pull down assay, and Western blotting experiments were carried out in the present study. We found that extracellular ATP induced calcium transient via IP(3)Rs (IICR) and the IICR were markedly decreased in ERp44 overexpressed Hela cells. The inhibitory effect of C160S/C212S but not C29S/T396A/ΔT(331-377) mutants of ERp44 on IICR were significantly decreased compared with ERp44. However, the binding capacity of ERp44 to L3V domain of IP(3)R(1) (1L3V) was enhanced by ERp44 C160S/C212S mutation. Taken together, these results suggest that the mutants of ERp44, C160/C212, can more tightly bind to IP(3)R(1) but exhibit a weak inhibition of IP(3)R(1) channel activity in Hela cells.
