[Methods] From January 2010 to June 2013,we studied 60 female genital condyloma accuminatum cases in the outpatient department of our hospital, these cases were randomly divided into two groups:group A(Bupleurum injection group) and group B(ShuRun suppository, namely a-2a interferon suppository group), the clinical curative effect of the two groups was observed. [Results] After treatment, group A,30 cases in al ,9 cases had complete recovery,12 cases had some effect,9 cases were invalid, the total effective rate was 70%; group B,the total of 30 cases,6 cases had complete recovery, 7 cases had some effect, 17 cases were invalid, the total effective rate was 43.3%, group A in the treatment of female genital condyloma acuminatum had better effect than the group B(P<0.05).After treatment,the total score of two groups al reduced effectively.The recurrence rate had no obvious difference between the two groups(P>0.05). [Conclusion] Bupleurum injection for treating female genital condyloma acuminatum has better clinical efficacy, can be considered for clinical use.

Objective To explore the value of virtual touch tissue quantification (VTQ) elastography and its influencing factors in identifying benign and malignant thyroid nodules.Methods A retrospective analysis was conducted in 210 cases of 240 thyroid nodules.Their images,including 2D ultrasound,color Doppler flow imaging (CDFI) and VTQ elastography,were reviewed,and the scanning view,the maximum diameter of the nodule,inside blood flow,calcifications and its depth beneath the skin were recorded.The value of shear wave velocity(SWV) in identifying benign and malignant thyroid nodules was calculated using receiver operating characteristic (ROC) curve.The influences of the maximum diameter of the nodules,calcifications,internal blood flow,the depth beneath skin and scanning views as well as type of pathology on the value of SWV were analyzed using multiple linear regressions (MLR).Results The sensitivity and specificity of VTQ in differential diagnosis of benign and malignant thyroid nodules was 74.8％ and 73.4％,respectively,and the area under ROC curve was 0.799.MLR indicated that the maximum diameter of the nodule,the type of pathology and internal blood flow were correlated with the SWV value (P ＜0.05),of which,the type of pathology was the important factor (standardized coefficient was-0.312).Microcalcifications,the depth of the nodules located and the scanning surface were not significantly related to SWV value (P ＞0.05).Conclusions VTQ can quantitatively provide the information on the hardness of thyroid tissue,which is of a definite value in the differential diagnosis of the nodules.The pathology of the nodule,its internal blood flow and maximum diameter are the factors that affect the value of SWV,and not its depth,scanning views and microcalcifications.

Objective:To determine the role of lncRNA TUG1 in pancreatic β cells functioning both in vitro and in vivo.Methods:The lncRNA TUG1 expression in mice pancreas,brain,muscle and other different tissues was examined through qRT-PCR.MTT,flow cytometry,GSIS,ELISA and immunochemistry analyses were performed to detect the effect of lncRNA TUG1 on insulin secretion in vitro and in vivo.Results:lncRNA TUG1 was highly expressed in pancreatic tissue compared with other organ tissues.Knockdown of lncRNA TUG1 expression resulted in decreased insulin secretion in β cells both in vitro and in vivo.Immunochemistry analyses showed decreased relative islet area after treatment with lncRNA TUG1 siRNA.Conclusions:Downregulation of lncRNA TUG1 expression can affect insulin secretion in pancreatic β cells in vitro and in vivo,and lncRNA TUG1 may represent a factor that regulates the function of pancreatic β cells.

BACKGROUND:Gastric cancer stem cels involved in the neoadjuvant chemotherapy and conventional treatment are closely associated with relapse of gastric cancer. However, this conclusion has not yet been confirmed.
OBJECTIVE:To investigate the effects of gastric cancer stem cels in tumor invasion and metastasis and its effect on angiogenesis ability.
METHODS:We prepared nude mouse models of gastric cancer to isolate and culture gastric cancer stem cels. Harvested gastric cancer stem cels were detected in cel scratch test, ring test, inhibition rate test, cel migration test and tumorigenicity test.
RESULTS AND CONCLUSION:After 7 days of culture, the cels exhibited adherent growth but a lack of regularity that most cels were in a tadpole shape. In the cel scratch test, the scratch width was significantly different at 0 and 24 hours (P < 0.05). Under an inverted microscope, the cels were found to form a ring in the ring test. The 50% inhibiting concentration of gastric cancer stem cels induced by oxaliplatin was significantly lower than that induced by 5-fluorouracil (P < 0.05). The number of cels passing through the basilar membrane was significantly increased after cel migration (P < 0.05). After implantation of gastric cancer stem cels, the gastric tissue quality was significantly higher than that in normal nude mice of gastric cancer (P < 0.05). These findings indicate that gastric cancer stem cels responsible for tumor invasion and migration have stronger angiogenesis ability.
