The influence of Gynostemma pentaphyllum extract ( G. P ) on the life span of fruit fly was observed. G. P (0.5% and 1.0%) significantly increased mean life span by 11.8% and 12.2%, respectiyely, when fed to male adults.At 0.25% concentraction, the female adults were found to yield an increase of 24.1% in mean life span and the male an increase of 18.5%.Rearing flics on 0. 5% G. P during both the developmental and adult stages proved to be even more effective than just feeding during the adult stage. The mean life span of male and female adults were increased by 53.3% and 46.1% , respectively, but at the higher concen-tration of 1.0%, the increase was 14.4% and 9.7%, respectively,G. P obviously improved the growth of larvae when given aconcentration of 0.5%,No marked change was observed in the copulatory rate of fruitflies after the treatment of 0.5% G.P.

Objective To compare the clinical values of laparoscopic surgery and laparoscopic surgery by pull through technique for anterior of rectum in patients with rectal cancer. Methods From Jan, 2013 to Jan, 2014, 120 patients with low rectal cancer were prospectively collected. The patients were randomly divided into study group (n= 60) and control group (n= 60). Patients in the study group were treated with laparoscopic surgery by pull through technique for anterior resection of rectum, while patients in the control group were treated with laparoscopic surgery. The primary outcomes were intraoperative situations, postoperative complications and recovery. Results When compared with the control group, patients in the study group got a significantly shorter operative duration [(132.32±14.92) vs (154.73±17.65) min, P=0.000];a signiifcantly lower postoperative drainage volume [(299.93±56.49) vs (365.24±68.94) ml, P= 0.000]; a significantly shorter gastrointestinal function recovery time [(57.42±5.84) vs (61.85±7.40) h, P=0.002]; and a signiifcantly less of length of hospital stay [(12.54±2.76) vs (14.75±2.10) d, P= 0.000]. There was no significant difference between the two groups in the amount of bleeding, the number of lymph node dissection, pneumonia, lower extremity arteriovenous thrombosis, incision infection, anastomotic leakage, intestinal obstruction, 2-year recurrence rate and mortality rate (P> 0.05). Conclusion laparoscopic surgery by pull through technique for anterior resection of rectum can accelerate postoperative recovery.

Objective To evaluate the clinical value of laparoscopic uItrasonography ( LUS) in u-rinary laparoscopic surgery .Methods In 6 cases of urological laparoscopic surgery , laparoscopic ultra-sound examination were taken , including 3 cases of simple renal cysts , 1 case of adrenal pheochromocyto-ma, 2 cases of hamartoma , were excised under the LUS guidance and the results were compared with the traditional simple laparoscopic surgery .Results With laparoscopic uItrasonography guidance , the bounda-ry and blood supply of cyst or tumor could be shown more clearly compared with trans -abdominal ultrasound . We could differ the tumors from dilated pelvis and renal calices , So the damage to the collecting system and renal blood vessels were avoided .With LUS guidance , tumors were excised more completely , so that re-mained tumor tissues would be avoided and normal renal tissues would be protected .Conclusion LUS may provide more precise surgical information and may play an important role guiding laparoscopic operation in urinary surgery .

Objective:This study aimed to analyze the factors affecting the outcome of cancer pain in patients with moderate and severe chronic cancer pain for clinical decision making. Methods: Data were collected from 426 cancer patients with moderate and severe chronic cancer pain, and the factors affecting pain treatment were analyzed. Results:A total of 85.6%of patients had good pain control in 3 days (NRS≤3). Multivariate logistic regression models showed that the pain of patients with bone metastases (P=0.026), breakthrough pain after stable pain control (P<0.001), and high MEDD (P<0.001) was poorly controlled. Moreover, age, sex, TNM stage, cause of pain, and medication ladder were not risk factors of pain control (P>0.05). Opioid combination with NSAIDs contributed to easier pain control (P=0.024). Digestive system tumors, pain intensity, limb pain, neuropathic pain, use of transdermal fentanyl matrix patch, multiple metastases in stage-IV patients were suggested to be risk factors of pain control in univariate logistic regression models (P<0.05). Conclusion: Bone metastases, breakthrough pain after pain relief, and high dose of MEDD were independent risk factors. Opioid combination with NSAIDs was a protective factor of pain control.

Background:Tissue microarray has been increasingly used in research of malignancies. It has been revealed that TGF-β signaling pathway contributes to the tumorigenesis and progress of malignancies. Aims:To determine the expressions of Runx3,Smad4,Cdk2 and p21,the key molecules in TGF-β signaling pathway by tissue microarray,and investigate their correlations with clinicopathological features and prognosis of gastric cancer. Methods:A total of 378 paraffin embedded tissue blocks,including 130 gastric cancer tissue and 248 para-cancer tissue from 130 patients undergoing radical resection of gastric cancer were obtained. Tissue microarray and immunohistochemistry were used to determine the expressions of Runx3,Smad4,Cdk2 and p21. Results:The aberrant expression rates of Runx3,Smad4, Cdk21 and p21 in gastric cancer tissue were significantly higher than those in para-cancer tissue(67. 7% ,35. 4% , 63. 8% and 70. 0% vs. 14. 1% ,12. 5% ,18. 1% and 37. 1% ,P < 0. 05,respectively). Aberrant expression of Runx3 was closely correlated with histological grade and lymph node metastasis of gastric cancer( P < 0. 05),while aberrant expressions of Smad4 and p21 were correlated with histological grade only(P < 0. 05);aberrant expression of Cdk2 was correlated with histological grade,lymph node metastasis and TNM staging(P < 0. 05). Pairwise correlations were seen among aberrant expressions of Runx3,Smad4 and p21 in gastric cancer,while Cdk2 was correlated with Runx3 only. Kaplan-Meier survival curve showed that 5-year survival rates in Runx3,Smad4 and p21 aberrant expression groups were significantly lower than those in normal expression groups(P <0. 05). Furthermore,Cox proportional hazard model indicated that Runx3 and Smad4 were independent prognostic factors for gastric cancer. Conclusions:Runx3,Smad4,Cdk2 and p21 might play pivotal roles in tumorigenesis and progression of gastric cancer. As interactions occurred among these four proteins,whether Runx3 and Smad4 could be used for predicting the prognosis of gastric cancer needs to be further studied.
