Objective To study the distribution and clinicopathological characteristics between VEGF-C and pefitumoral lymph vessels density(PLVD) in breast cancer tissue, and to investigate the development and the mechanism of breast cancer-related lymphoedema (BCRL). Methods VEGF-C and VEGFR-3 were detected by using immunohistochemical technique for the detection of VEGF-C and its receptor VEGFR-3 in forty-seven breast cancer specimens. We measured the patients' circumferences of bilateral upper limbs to determine whether there was lymphoedema and made classification in the follow-ups. Results VEGF-C was positive in 33 out of 47 cases. PLVD significantly increased in VEGF-C positive groups (30.39±10. 46) than in negative groups (23.16±11.67) (P<0.05). VEGF-C semi-quantitative score was in a positive correlation with PLVD (r=0.334). The positive expression rate (42.55%) and semi-quantitative score (3.68±1.59) of VEGF-C increased in the lymph node positive group than in the negative group, PLVD increased in the lymph node positive group compared with that in negative group (32.12±10.29 vs. 24.82±11.06), P<0.05. The risk of lymphoedema increased in the VEGF-C negative group (5/14) compared with that in the positive group (3/33) (P<0.05). Conclusion VEGF-C has a high rate of positive expression in breast cancer, and is positively correlated with PLVD. High expression of VEGF-C can reduce the risk of BCRL in breast cancer.

Objective To study the locations, types and causes of different pseudoaneurysms in order to find out the optimal individualized treatment for different pseudoaneurysms. Methods Different methods were applied in treating 21 patients with pseudoaneurysm, which were located at limb (n = 11 ), spleen (n =3), kidney (n = 2) , common lilac artery (n = 1), internal iliac artery (n = 1), gallbladder (n = 1) and penis (n = 1 ). Different managements were employed in treating these pseudoaneurysms. Temporary obstruction of blood circulation with balloon together with arterial anastomosis or direct incision neoplasty was performed in 9 cases with pseudoaneurysms at limb arteries close to the larger joints. Endovascular stent graft was used to isolate the trunk type of pseudoaneurysm in 4 cases, in 2 of them branch arterial embolism and stent graft endovascular exclusion were applied as they had common iliae artery trunk type of pseudoaneurysm at the opening of internal iliac artery. Gelfoam together with metallic coils embolization was employed in 6 cases with terminal type of pseudoaneurysms. Results After different treatments, tumor cavities disappeared in the 21 cases with pseudoaneurysms. Distal arterial pulse returned to normal and no nerve damage occurred in 11 cases with limb pseudoaneurysms. No internal hemorrhage was observed and distal blood circulation returned to normal after graft endovascular exclusion in 2 eases with pseudoaneurysms at spleen artery trunk and in 2 cases with pseudoaneurysms at iliac artery trunk. In 6 cases with terminal type of pseudoaneurysms,the tumor cavity disappeared, hemorrhage stopped and no ischemic necrosis of organ occurred. But one of them with multiple traumatic pseudoaneurysms located at the second grade branch died one week after embolism due to a serious pelvic trauma accompanied with serious infection. Conclusion Based on the locations, types and causes of pseudoaneurysms, different individualized treatment should be adopted in order to obtain optimal results with least damages.

Objective To explore the relationship between G-protein β3 subunit (GNB3) gene C825T polymor?phism and the weight gain of schizophrenics treated with olanzapine. Methods Ninety schizophrenics of first time hospi?talization were collected and treated with olanzapine for 12 weeks. The changes of body weight and body mass index (BMI) were detected before and after 12-week olanzapine treatment. The GNB3 gene C825T polymorphism in patients was determined by polymerase chain reaction (PCR) and DNA sequencing technique. The correlation of GNB3 gene C825T polymorphism and change of clinical parameters was analyzed. Results Body weight and BMI in patients were all increased significantly after treatment (all P<0.01). Weight gain rate (WGR) and increase of BMI in the TT genotype group were higher than those in the CC genotype group (all P<0.01). WGR and increase of BMI in the T-allele carrier (TT and CT genotypes) were higher than those in the T-allele non-carrier (CC genotype) (all P<0.01). There was signifi?cant difference in distribution of genotypes between WGR ≥7% group (CC 15.69%, CT 54.90%, TT 29.41%) and WGR <7% group (CC 38.46%, CT 43.59%, TT 17.95%) (P<0.05). The frequency of T-allele in the WGR≥7% group (63.33%) was higher than that in the WGR<7%group (39.74%) (P<0.05). Multi-variable linear regression indicated that TT genotype (contrasted with CC genotype) was an influential factor for change of body weight after treatment with olan?zapine (β=1.83, standardized β=0.29, P<0.01). Conclusions The GNB3 gene C825T polymorphism is associated with olanzapine-induced weight gain.

OBJECTIVESTo evaluate the efficacy and advantage of minimally invasive esophagectomy for surgical treatment of submucosal esophageal cancer compared to conventional open procedure.
METHODSClinical data of consecutive 168 patients with stage T1b submucosal esophageal cancer undergoing minimally invasive esophagectomy (MIE, esophagectomy by thoracoscope, stomach freeing by laparoscope or open abdomen, cervical esophagogastric anastomosis) or conventional open esophagectomy (OE) at the Shanghai Chest Hospital between January 1, 2012 and December 31, 2014 were reviewed retrospectively. Intraoperative and postoperative information was compared between the two groups.
RESULTSBoth groups were equally stratified by sex, body mass index and age. No patient of MIE group was transferred to open operation. As compared to the OE group, the MIE group had significantly more harvest lymph nodes (median 12 vs. median 9, P=0.004), lower rate of postoperative pneumonia [5.8% (4/69) vs. 21.2% (21/99), P=0.011] and pleural effusion [8.7% (6/69) vs. 23.2% (23/99), P=0.027], and shorter hospital stay (median 11 d vs. median 14 d, P=0.041), but positive margin was found in 1 case. There were no significant differences of respiratory failure, pneumothorax, atrial arrhythmia, pulmonary embolism, recurrent nerve palsy, anastomotic leak, reoperations and 30-day mortality between the two groups. Multivariate logistic analysis revealed recurrent nerve palsy, anastomotic leak and surgical approach were found to be the main factors of hospital stay within postoperative 12 days, while leakage when the in-hospital time more than 12 days. Kaplan-Meier analysis showed that the surgical approach was the independent factor of hospital stay, MIE could shorten the hospital stay (P=0.013).
CONCLUSIONMIE should be considered as the standard approach in the treatment of T1b submucosal esophageal cancer.

Objective As the population ages,clinicians are increasingly confronted with octogenarians with early-staged non-small cell lung cancer(NSCLC).We reviewed the outcomes of octogenarians who underwent lobectomy for clinical stagc Ⅰ NSCLC,to determine whether there was a benefit to the VATS approach in this group,and to analysis the risk factors of complication and survival.Methods We conducted a retrospective single-institution review of patients age 80 years or greater who underwent lobectomy for NSCLC from January 2006 to December 2016.Clinical outcomes including complication rate and survival rate were analyzed.Results 162 octogenarians underwent lobectomy:98 VATS and 64 through open thoracotomy.Compared with thoracotomy,VATS patients had fewer complications (14.3 % vs.28.1%,P =0.03),shorter length of tube duration [(3.5 ± 1.5) days vs.(4.9 ± 2.0) days,P =0.04],and shorter length of stay [(5.5 ± 2.1) days vs.(7.8 ± 3.5) days,P =0.04].For patients with pathologic stage Ⅰ disease,the 5-year overall survival was 64.5%,for stage Ⅱ was 38.1%,and for stage Ⅲ was 20.1%.The 5-year overall survival rates of pathological stage Ⅰ and stage Ⅱ,Ⅲ are of significant differences(P =0.001).In a multivariate logistic regression analysis,the approach of thoracotomy emerged as an independent predictor of complication (OR =1.94,95% CI 1.214-5.135,P =0.03).In a multivariate COX regression analysis,pathological stage(OR =2.01,95%C1 1.453-5.865,P=0.03) and ASA(OR =1.81,95%CI 1.188-4.015,P =0.04) are independent predictors of over survival.Conclusion Octogenarians with NSCLC can undergo resection with low mortality and survival among stage Ⅰ patients,which is comparable with the general lung cancer population.The VATS approach reduces morbidity in this age demographic,resulting in shorter length of tube duration and shorter stay,while the approach of thoracotomy is an independent predictor of complication.Our study also demonstrated that pathological stage and ASA are independent predictors of overall survival rate.

Objective:To discuss the safety and feasibility for the use of 3D uniportal VATS sleeve resection.Methods:Totally 32 patients with central lung cancer received 3D uniportal VATS sleeve resection(group A) from June 2017 to May 2020 at Shanghai Chest Hospital. Meanwhile, 63 patients received conventional VATS sleeve resection(group B). The clinicopathological and perioperative outcome data were retrospectively collected and analyzed.Results:The baseline clinicopathological characteristics between these two groups were statistically similar. Compared with group B, the mean operative time[(174.19±73.69)min vs.(212.46±50.02)min, P=0.004] and blood loss[(73.13±42.70)ml vs.(130.48±133.72)ml, P=0.020] of group A were decreased, harvested lymph node stations was increased(7.63±1.59 vs. 6.76±1.70, P=0.018). Lymph nodes dissected showed no statistical difference(1.31±1.58 vs 1.21±1.96, P=0.803). There was no intraoperative death in both groups. Inspiringly, group A possessed lower rate of conversion to thoracotomy(0 vs. 36.5%, P=0.000), shorter chest drainage durations[(4.88±1.15)days vs.(6.81±3.8)days, P=0.007]. Although there were no deaths during hospitalization in both groups, the incidence of postoperative complications in group A was significantly lower than that in group B(25.0% vs. 47.6%, P=0.046). It also presented more complicated operations including pulmonary artery plasty(25.0% vs. 6.3%, P=0.024) and carina plasty(12.5% vs. 1.6%, P=0.005) against group B. Conclusion:3D uniportal VATS was a safe and feasible technique for the surgical treatment of central lung cancer when conducting a thoracoscopic sleeve resection.
