Objective To compare the surgical outcomes between laparoscopic and open surgeries in treatment of ectopic oviduct pregnancy, and investigate the clinical value of laparoscopic surgery. Methods Two hundred and forty-six patients with ectopic oviduct pregnancy in our hospital from June 2009 to March 2013 were retrospectively analyzed. 134 cases were treated with laparoscopic operation and 112 with open surgery. Some parameters such as operative time, blood loss, usage of pain-killer, hospital stay were compared between both groups. Results All operations were successful. Laparoscopic surgery was shown to be superior to open operation in the parameters of operative time, blood loss, usage of pain-killer and hospital stay ( < 0.05) . Conclusion Compared with open operation, laparoscopic surgery has the advantages of less trauma and rapid postoperative rehabilitation. It may become the first line treatment for ectopic oviduct pregnancy.

Objective To investigate the predictive value of whole nodule size and solid component size of pulmonary subsolid nodules (SSNs)with different window setting on preoperative HRCT for pathologic grade in lung adenocarcinoma.Methods We retrospectively evaluated preoperative chest HRCT and pathological data of 125 patients with 127 surgically resected lung adenocarcinoma manifesting as SSNs.All specimens were divided into two groups:a total of 69 SSNs in group A,including 22 adenocarcinomas in situ (AIS) and 47 minimally invasive adenocarcinoma (MIA);a total of 58 SSNs in group B,including invasive adenocarcinoma (IAC).Observer 1 used computer aided diagnosis software to measure the volume of whole nodule with lung window setting (WNLW),volume of solid component with lung window setting (SCLW),volume of solid component with mediastinal window setting (SCMW) and volume of solid component with threshold of-300 HU(SCT) of all SSNs.Observer 2 randomly selected 50 SSNs and repeated all the measurements.The interobserver agreement regarding quantitative measurements were evaluated by using intraclass correlation coefficient(ICC).The differences of all quantitative features between two groups were evaluated by Mann-Whitney U test.All the quantitative features were evaluated by using univariate logistic regression analysis,significant quantitative features identified by univariate logistic regression analysis were included in the multivariate logistic regression and independent predictors of pathological grade were obtained.Receiver operating characteristic analysis was conducted for the independent predictive factors that exhibited statistically significant differences in the multivariate logistic regression.Results The interobserver agreement regarding quantitative features were excellent (ICC＞ 0.75).The WNLW,SCLW,SCMW and SCT of group B were significantly larger than those of group A (P＜ 0.001).The univariate logistic regression analysis indicated that WNLW,SCLW,SCMW and SCT were significant (P＜0.001),the multivariate logistic regression analysis indicated that SCT was the independent predictive factor (OR=1.013,95％CI:1.006—1.020,P＜0.001).When SCT larger than 139.00 mm3,SSN was significantly associated with IACs (AUC=0.887,sensitivity=81％,specificity=93％).Conclusion SCT of SSNs on preoperative HRCT can be used to distinguish between AIS-MIA and IAC,which may provide information for choice of operation.

Objective To investigate the predictive value of the whole nodule size and solid component size of lung adenocarcinoma manifesting as subsolid nodule(SSN) in three different dimensions for pathologic grade.Methods We evaluated retrospectively preoperative chest HRCT data of 125 patients with 127 SSNs surgically resected and pathologically conformed lung adenocarcinomas.All specimens were divided into two groups: a total of 69 SSNs in group A, including 22 AIS and 47 MIA;a total of 58 SSNs in group B, only including IAC.Computer aided diagnosis software were used to measure the one dimension maximum diameter of solid component with lung window setting(1D-SCLW),two dimension maximum diameter of solid component with lung window setting(2D-SCLW),one dimension maximum diameter of solid component with mediastinal window setting(1D-SCMW),two dimension maximum diameter of solid component with mediastinal window setting(2D-SCMW),one dimension maximum diameter of whole nodule with lung window setting (1D-WNLW), two dimension maximum diameter of whole nodule with lung window setting (2D-WNLW), and volume of solid component with threshold of-300 HU (SCT) of all SSNs.Results 1D-SCLW, 2D-SCLW,1D-SCMW,2D-SCMW,1D-WNLW,2D-WNLW and SCT of the group B were significantly larger than those of the group A(P=0.000).ROC analyses indicated that the diagnostic efficiency of SCT for the pathologic grade was the highest among 7 CT features(AUC=0.887, sensitivity:81%,specificity:93%);The cut-off values of 1D-SCLW,2D-SCLW,1D-SCMW,2D-SCMW,1D-WNLW, 2D-WNLW and SCT were 17.50 mm,14.75 mm,9.50 mm,7.75 mm,0.50 mm,1.25 mm and 139.00 mm3.Multiple Logistic regression analysis revealed that SCT was the independent predictor of pathologic grade(OR=4.978,95%CI=1.430-17.331,P=0.012).SCT of 139.00 mm3 or greater was a significant indicator of IAC.Conclusion Among the whole nodule size and solid component size of SSN in three different dimensions on preoperative HRCT, SCT is found to be the independent predictor of pathologic grade, which may provide reference for surgery.

Objective To evaluate the effect of CT temporal subtraction(TS) for detection of lung nodules.Methods 80 cases of CT images (current and previous CT images) and corresponding CT TS images were presented, which included 30 cases with nodules(75 nodules) and 50 controls.4 observers, including 2 radiologists and 2 residents, indicated their confidence level regarding the presence of a new emerging or larger or solid component than before,which first used standard CT images, then with the addition of CT TS images.Receiver operating characteristic(ROC) curve analysis was used to evaluate the observers'' performance.Results The mean value of the area under the ROC curve (AUC) were 0.860 and 0.925 for four observers without and with TS images,respectively(P<0.01).Average sensitivity for detection of lung nodules was improved from 77.3%(58/75) to 89.3%(67/75) by using CT TS images.Conclusion The use of CT TS images can significantly improve radiologists'' performance for detection of lung nodules,especially when a small size solid or subsolid nodule presents near the pulmonary hilum.CT TS is more helpful for residents.

According to the transcriptome dataset of Panax notoginseng, the key geranylgeranyl pyrophosphate synthase gene (GGPPS) in terpenoid backbone biosynthesis was selected to be cloned. Using specific primer pairs combining with RACE (rapid amplification of cDNA ends) technique, the full-length cDNA sequence with 1 203 bp, which containing a 1 035 bp open reading frame, was cloned and named as PnGGPPS. The corresponding full-length DNA sequence contained 2 370 bp, consisted of 1 intron and 2 exons. The deduced protein PnGGPPS contained 344 amino acids and shared more than 73% identity with GGPPS from Ricinus communis and Salvia miltiorrhiza. PnGGPPS also had specific Aspartic acid enrichment regions and other conserved domains, which belonged to the Isoprenoid-Biosyn-C1 superfamily. The quantitative real-time PCR showed that PnGGPPS expressed in different tissues of 1, 2, 3 years old root, stem, leaf and 3 years old flower, and the expression level in 3 years old leaf was significant higher than that in other organs, which suggested that it might not only be involved in the regulation of the growth and development, but also be associated with the biosynthesis of chlorophyll and carotenoids, the development of chloroplast, the shade habit and the quality formation of P. notoginseng.

To study the chemo-preventive effect of the supercritical extracts from Angelica sinensis (SFE-AS) on induced colorectal carcinoma in mice by using the AOM/DSS-induced male mice colorectal carcinoma model, and discuss its possible action mechanism. Male Balb/c mice were subcutaneously injected with single dose of azoxymethane (AOM, 10 mg x kg(-1) body weight). One week later, they were given 2% dextran sodium sulfate (DSS) in drinking water for 7 days to induce colorectal carcinoma. Each drug group was orally administered with supercritical extracts from Angelica sinensis at 15, 30, 60 mg x kg(-1) until the 17th week. The tumor incidence rate of the SFE-AS group, mice tumor-bearing quantity and tumor-bearing volume of the SFE-AS group were lower than that of the AOM/DSS model control group, which may be related with the significant reduction of PCNA, COX-2, iNOS in the AOM/DSS-induced mouse colorectal carcinoma model associated with inflammation by SFE-AS. According to the results of this study, SFE-AS showed an intervention effect in the incidence and development of AOM/DSS-induced mouse colorectal carcinoma associated with inflammation, and could be further used in chemo-preventive studies on human colorectal carcinoma.
