Objective To compare the advantages and disadvantages of uniportal video-assisted thoracic surgery(uniportal-VATS)and three portal VATS in treatment of benign pulmonary diseases. Methods The clinical data of 66 patients with benign pulmonary disease treated by VAST from June 2015 to October 2016 were retrospec-tively analyzed. The patients were divided into two groups according to the specific operation. There were 32 patients (18 males and 14 females)in uniportal-VATS group. There were 34 patients(18 males and 16 females)in three portal VATS group. The operative time ,intraoperative blood loss ,thoracic drainage volume at 24 h after opera-tion,incision length,and the time of postoperative drainage of thoracic cavity,postoperative third day pain score and complication rate were compared between the two groups. Results The patients in the experimental and the control groups were successfully operated according to the scheduled protocol. No thoracotomy was performed. There was no statistical difference in the volume of blood loss,the volume of pleural drainage after 24 hours,the time of postoperative drainage of thoracic cavity ,the length of hospital stays and postoperative complications in uni-portal-VATS group and three portal VATS group(P>0.05). The pain score and postoperative third day pain score of the uniportal-VATS group was better than that of the three portal VATS group(P<0.05),but the operation time of the uniportal-VATS group was longer than that of the three portal VATS group(P<0.05). Conclusion Uniportal-VATS is safe and feasible for the treatment of benign lung diseases. It is more minimally invasive and beautiful than traditional three-hole thoracoscopic surgery. It is worthy of promotion and has broad prospects.

Objective To evaluate food intolerance sensitivity among 2962 health check-up receivers from the First Hospital of China Medical University.Methods Serum samples of 2962 adults were collected from January 2008 to June 2010.Serum allergen-specific IgG antibodies of 14 kinds of food were detected by ELISA.The data were analyzed by using One-way analysis of variance.Results In this study,the rate of food intolerance was 0.4%(mushrooms) to 38.0%(eggs).Higher rates of food intolerance were found in egg,crab,shrimp,milk,and cod fish(Eggs 32.5%,crabs 26.0%,shrimps 19.8%,milk 13.8%,and cod fish 12.0% respectively).However,wheat,pork,and mushroom showed relatively lower rates of food intolerance(Wheat 0.8%,pork 0.4%,and mushrooms1.4% respectively).Positive reaction to food intolerance was even stronger in women(9.4% versus 8.2%).Conclusion It is discovered by study that in general population,the diversity of intolerance among different food is associated with 4 factors: gender; age; feature of food; individual diversity.It is recommended that the status of intolerance to food in the general population be investigated by health management.

Background It has been demonstrated that αvβ3/αvβ5 and α5β1 integrins are overexpressed in neovascular tissue.Consequently,peptide containing the RGD (Arg-Gly-Asp) sequence,which exists in ligands of integrins,is effective in targeting therapeutic reagents to neovascular endothelium.ObjectivePresent study aims to investigate the antiangiogenetive effects of liposome mediated plasmid encoding endostatin with RGD sequence on alkali burn-induced corneal neovascularization (CNV) in rabbits.MethodsCNV models induced by alkali burn were established in 72 eyes of 36 New Zealand white rabbits by putting the filter paper with 1 mol/L NaOH at the central cornea for 20 seconds.The animal models were divided into four groups randomly.0.2mL of liposome and plasmid encoding RGD-ES complex (liposome mediated pCI-RGD-ES injection group),liposome and plasmid encoding ES complex (pCI-ES injection group),liposome and carrier plasmid (pCI) complex (pCI-ES injection group),and PBS were subconjunctivally injected respectively in the models from four groups twice a week for two weeks.The growth status of CNV was observed on day 1,3,7,14 after alkali burn under the slim lamp microscope.Experimental animals were sacrificed on the 3rd,7th and 14th day and the expression of VEGF in CNV was detected by immunohistochemistry.The number of corneal microvessels was counted based on the number of CNV cross-section under the light microscope.ResultsCNV area was significantly smaller in liposome mediated pCI-RGD-ES injection group and pCI-ES injection group compared with PBS group at different time points (P＜0.01),but no significant difference was seen in CNV area between pCI-ES injection group and PBS group at different time points (P＞0.01).The changes of number of corneal microvessels was followed a similar fashion as the change of CNV area.Expression of VEGF in cornea was obviously stronger in pCI-ES injection group and PBS group than liposome mediated pCI-RGD-ES injection group and pCI-ES injection group.ConclusionEndostatin with RGD sequence could effectively inhibit corneal neovascularization,and liposome is proved to be a potent carrier in gene transfer.

Objective To observe the inhibitory effect of ginsenoside RG3 on choroidal neovascularization in vitro and in vivo.Methods MTT assay was used to evaluate the inhibitory effect of ginsenoside RG3 on human umbilical vein endothelial cells (HUVEC) proliferation in vitro,and HUVEC were divided into normal group,in which the cells were cultured in DMEM/F-12 medium containing 10％ fetal bovine serum,control group with its medium containing 2 g · L-1 dimethyl sulfoxide (DMSO) and different concentrations of ginsenoside RG3 administration group (12.5 μmol · L-1,25.0 imol · L-1,50.0 μmol · L-1,100.0 μmol · L-1).Then the absorbance value was measured after 6 h.Then,a small amount of HUVEC was collected again and divided into control group with its medium containing 2 g · L-1 DMSO and 100.0 μrnol · L-1 ginsenoside RG3 group for detecting the inhibitory effect of ginsenoside RG3 on tubular formation and vascular endothelial growth factor (VEGF) protein expression by Western blots.In vivo,20 male C57BL/6J mice were collected and randomly divided into control group and ginsenoside RG3 group.After 2 weeks,followed by establishment of model with a semiconductor laser,fundus fluorescein angiography was performed on the 1 st day and 21 st days after treatment.Results MTT results showed that absorbance value of the normal group,control group,12.5 μnol · L-1,25.0 μmol · L-1,50.0 μmol · L-1,100.0 μmol · L-1 ginsenoside RG3 group was 0.43 +0.17,0.43 ±0.05,0.33 +0.02,0.24 +0.02,0.18 ±0.01,0.15 ±0.01 accordingly,and there was no significant difference between the control group and the normal group (all P ＞ 0.05),but the difference between the other group and control group was statistically significant (all P ＜ 0.05).Tubular formation assay showed that the number of tubular formation in the control group and 100.0 μmol · L-1 ginsenoside RG3 group was 72.5 + 5.56 and 11.33 ± 3.71,respectively,and the difference was statistically significant (P ＜ 0.01).Western blots showed that the relative expression of VEGF in 100.0 μmol · L-1 ginsenoside RG3 group (0.14 ±0.01) was significantly lower than that in the control group (0.46 ±0.01),and the difference was statistically significant (P ＜0.01).In vivo fundus fluorescein anglography showed that the fluorescein leakage area of ginsenoside RG3 group was lower than that of the control group.Conclusion Ginsenosid RG3 can inhibit the formation of choroidal neovascularization by inhibiting the expression of VEGF in vitro and in vivo.
