Objective:To develop a new type of biopsy sampling device which is usable, easy practice and has long service life.Methods:Pneumatic alarm device is added to the traditional biopsy system. During the process of doctor draw piston stem, when the syringe tube was blocked, air can drive the sealing cover open due to the external pressure is greater than the pressure of the cylinder, it is from the holes into the cylinder body to maintain the pressure balance and trigger the air alarm device alarm; when cylinder pressure restored normally, rod drives the sealing cover is closed under the action of the spring.Results: The new system is able to control the biopsy sampling pull the speed of the piston stem, and can automatically exhaust and alarm on the needle plug.Conclusion: The utility model has the advantages of convenient use, strong practicability and long service life. It’s worthy of popularization.

Objective To compare the effect of entecavir and lamivudine combined with adefovir in treatment of patients with e antigen -positive chronic hepatitis B.Methods 72 patients with HBeAg positive chronic hepatitis B were randomly divided into group Ⅰ (36 cases)and group Ⅱ (36 cases).Group Ⅰ was treated by grace entecavir,group Ⅱ was treated with adefovir and lamivudine,two groups were treated for 24 months.The HBV -DNA negative rate,ALT recovery rate,HBeAg seroconversion rate,negative conversion rate of HBsAg,HBeAg and HBeAb conversion rate of the two groups were compared after 6 months,12 months and 24 months treatment.Results After treatment for 6 months,12 months and 24 months,the HBV -DNA negative rate,HBeAg negative conversion rate, HBeAg and HBeAb rate in the two groups had no statistically significant differences.After 6 months and 12 months treatment,the ALT recovery rates of group Ⅰ were 52.78%,83.33%,which were significantly higher than 27.78%, 38.89% of group Ⅱ,the differences were statistically significant(χ2 =4.677,14.961,all P <0.05 ).The total response rates of 6 months,12 months and 24 months after treatment were 47.22%,77.78%,88.89%,72.22%, 83.33% and 44.44%,respectively.There were no significant differences between the two groups(all P >0.05). Conclusion There is similar effect of entecavir and lamivudine combined with adefovir in treatment of patients with e antigen -positive chronic hepatitis B,which can inhibit HBV replication and improve liver function,and the security was good,but entecavir has better ALT normalization rate at early,the treatment should be selected according to clini-cal practice.

Laparoscopic minimally invasive surgery technology is rapidly developing in the tumor treatment field. Due to the lack of space perception of the previous 2 D laparoscopic surgery, it has been unable to meet the current needs, and then 3 D laparoscopic technology emerged and got widely development. This paper summarizes the difference between the 3 D laparoscopic technique and traditional 2 D laparoscopic technology, and then analyzes the classification of 3 D signal display technology and common format. At the same time, this paper introduces the integration operating room structure with 3 d technology, signal format, and signal transmitting method. Finally, this paper prospected the application foreground for 3 D laparoscopic technology in the operating room.

AIM:To evaluate the influence of scutellarin on the expression of vascular endothelial growth factor ( VEGF) in high glucose-treated human retinal pigment epithelial cell line ARPE-19 and to observe the effects of scutellarin on the protein expression of VEGF, p-ERK and VEGFR2 in the retinas of type II diabetic rats.METHODS: Cultured ARPE-19 cells were divided into normal control group, scutellarin group, high glucose group and high glucose+scutellarin group.The protein levels of VEGF, p-ERK and VEGFR2 were measured by Western blot.The VEGF release in ARPE-19 cells was detected by ELISA.Normal rats were randomly divided into normal control group and scutellarin group.Diabetic rat model was established by feeding with high-fat diet and injecting with streptozocin, and randomly divided into diabetes group and diabetes treated with scutellarin group.After 16 weeks, the eyes were removed.The morphological changes of the retinas were observed under light microscope with HE staining, and histopathological score was recorded.The expres-sion of VEGF in the retinas was observed by the method of immunohistochemistry.RESULTS:Compared with normal con-trol group, the protein levels of VEGF, p-ERK and VEGFR2 in the ARPE-19 cells decreased in scutellarin group, but in-creased in high glucose group.The histopathological score of the retinas showed significant difference among diabetes group, diabetes treated with scutellarin group and normal control group, and no significant difference between normal con-trol group and scutellarin group was observed.The expression of VEGF increased in diabetic group and was significantly higher than that in scutellarin treatment group (P<0.05).CONCLUSION:Scutellarin inhibits the increased protein le-vels of VEGF, p-ERK and VEGFR2 in ARPE-19 cells, and decreases the expression of VEGF in the retinas of diabetic rats.The suppression of the diabetic retinopathy development by scutellarin may be partly involved in the ERK/MAPK pathway.
