Objective    To compare the perioperative outcomes between robot-assisted complex segmentectomy and simple segmentectomy for stage ⅠA non-small cell lung cancer (NSCLC). Methods    The clinical data of 285 patients with NSCLC undergoing robot-assisted thoracic surgery (RATS) in our hospital from January 2015 to August 2021 were retrospectively analyzed. There were 105 males and 180 females aged 23-83 years. The patients were divided into a complex segmentectomy group (n=170) and a simple segmentectomy group (n=115) according to tumor location and surgical method. The clinical pathological baseline characteristics and perioperative outcomes between the two groups were compared, including operative time, blood loss volume, dissected lymph nodes, conversion rate, postoperative duration of drainage, postoperative hospital stay, the incidence of persistent air leakage and postoperative 30 d mortality. Results    There was no statistical difference in baseline data between the two groups (P>0.05). No postoperative 30 d death was observed. One patient in the complex segmentectomy group was transferred to thoracotomy. No statistical difference was observed between the two groups in the operative time (97.36±38.16 min vs. 94.65±31.67 min, P=0.515),  postoperative duration of drainage (3.69±1.85 d vs. 3.60±1.90 d, P=0.679), postoperative hospital stay (4.07±1.85 d vs. 4.05±1.97 d, P=0.957), dissected lymph nodes (5.15±3.53 vs. 5.13±2.93, P=0.952), incidence of blood loss volume<100 mL (98.2% vs. 99.1%, P=0.650), and incidence of postoperative persistent air leakage (6.5% vs. 5.2%, P=0.661). Conclusion    The safety and effectiveness of robot-assisted complex segmentectomy and simple segmentectomy are satisfactory in the treatment of stage ⅠA NSCLC. The perioperative results of RATS complex segmentectomy and simple segmentectomy are similar.

Objective    To investigate the effectiveness and safety of robotic lobectomy in clinical N0 lung malignant tumor≥3 cm. Methods    We retrospectively analyzed the clinical data of 182 patients with lung malignant tumor≥3 cm receiving robotic or thoracoscopic lobectomy at Shanghai Chest Hospital in 2019. The patients were divided into a robotic surgery group (RATS group) and a thoracoscopic surgery group (VATS group). There were 39 males and 38 females with an average age of 60.55±8.59 years in the RATS group, and 51 males and 54 females with an average age of 61.58±9.30 years in the VATS group. A propensity score matching analysis was applied to compare the operative data between the two groups. Results    A total of 57 patients were included in each group after the propensity score matching analysis. Patients in the RATS group had more groups of N1 lymph node dissected (2.53±0.83 groups vs. 2.07±0.88 groups, P=0.005) in comparison with the VATS group. No statistical difference was found in operation time, blood loss, postoperative hospital stay, number of N1 and N2 lymph nodes dissected, groups of N2 lymph node dissected, lymph node upstage rate or postoperative complications. The hospitalization cost of RATS was higher than that of VATS (P<0.001). Conclusion    In contrast with thoracoscopic lobectomy, robotic lobectomy has similar operative safety, and a thorough N1 lymphadenectomy in patients with clinical N0 lung malignant tumor≥3 cm.

Objective： ：To investigate the expression of miR-137 in cervical cancer tissues and cells, and to explore its effect on proliferation, migration and invasion of cervical cancer cells as well as the mechanisms. Methods： ：Thirty-two pairs of cervical cancer tissues and corresponding para-cancerous tissues that surgically resected at the Department of Gynecology and Obstetrics of Dongguan People's Hospital from January 2017 to March 2018 were collected for this study. In addition, cervical cancer cell lines C33A, HeLa, SiHa and cervical epithelial immortalized cell line H8 were also collected. The expression of miR-137 in cervical cancer tissues and cell lines was detected by RT-PCR. miR-137 mimics and miR-137 NC were respectively transfected into C33Aand HeLa cells, and the effects of miR-137 over-expression on proliferation, migration and invasion of cervical cancer cell lines were observed by CCK-8 and Transwell assay. Luciferase reporter gene assay and WB were used to determine the relationship between miR-137 and Wnt5a in cervical cancer. Wnt5a over-expression vector was constructed, and the effects of simultaneous over-expression of Wnt5a and miR-137 on proliferation, migration and invasion of C33Aand HeLa cells were observed. Results： ：The expression level of miR-137 was significantly down-regulated in cervical cancer tissues and cell lines, as compared to para-cancerous tissues and H8 cells (all P<0.05). The over-expression of miR-137 significantly inhibited cell proliferation, migration and invasion of C33A and HeLa cells (all P<0.05). Moreover, Wnt5a was identified as a target of miR-137 by luciferase reporter gene assay. Furthermore, Wnt5a over-expression, to a certain degree, attenuated the suppressive effects of miR-137 on the proliferation, migration and invasion of C33A and HeLa cells. Conclusion： ：miR-137 can inhibit the proliferation, migration and invasion of cervical cancer cells via targeting Wnt5a, which may be an effective target for the treatment of cervical cancer.

Objective To explore the clinical value of two-dimensional speckle tracking imaging (2DE-STI) by measuring global longitudinal strain (GLS) in normal children.Methods Totally 176 normal children underwent cardiac ultrasound examination,the left ventricular GLS were measured,and the difference of GLS between gender was analyzed.And the changes of GLS with body surface area (BSA) and age were discussed.Results GLS had no significant difference between male and female ([-24.90 ± 2.06]％ vs [-24.93 ± 2.01]％,t =0.83,P =0.934).GLS had significant differences among different BSA groups (F=3.84,P =0.003),and the differences of GLS in BSA＞ 1.0 group and the other five groups were statistically significant (all P＜0.05).GLS had statistically significant differences among different age groups (F=4.81,P=0.001),and the differences of GLS in ＞9 years old group and the other four groups were statistically significant (all P＜0.05).Conclusion Left ventricular GLS presents certain regularity with children's growth.

OBJECTIVETo identify the value of lymphography in the location and treatment decision of chyle leakage.

METHODSThe clinic data of 177 patients suffered from chyle leakage admitted in 6 medical centers in Shanghai from February 1998 to December 2014 was analyzed retrospectively. There were 94 male and 83 female patients aging from 9 to 84 years with a mean of 49 years, including 128 cases of chyluria, 34 cases of primary chylothorax and 15 cases of other chyle leakage. All patients had failed to conservative treatment more than 2 weeks. Pedal lymphography was performed in every patient to investigate the site and range of chyle leakage. Effect of surgical or conservative management was compared according to the different results of lymphography.

RESULTSNo serious complication was noticed. For all 177 patients, lymphography showed localized lymphatic diseases in 148 cases (83.6%), including 125 cases of lymphatic renal pelvic leaks, 14 cases of unilateral identified leak within thorax and 9 cases of chyle leakage in neck, heart, abdomen or scrotum. Among these patients, surgical treatment cured 129 and improved 3 patients but failed in 2 patients, while the remaining 14 cases had their leaks decreased after lymphography and cured by conservative management. For those 15 patients having disseminated lymphatic diseases or 14 with no abnormality under lymphography, surgery only cured 2 and improved 1 patient but failed in 8 patients (with 3 death), whereas continuous conservative treatment cured 11 patients, improved 5 patients but only failed in 2 patients (with one death). For localized leakage, surgical treatment showed better efficacy (98.5% vs. 3/11), whereas conservative treatment had significantly higher successful rate than surgical interventions in patients with disseminated lymphatic diseases or no abnormality under lymphography (16/18 vs. 3/11).

CONCLUSIONSLymphography could identify the location and range of complicate chyle leakage failed to primary conservative management. Patients with disseminated lymphatic diseases or no abnormality under lymphography would be better managed by continuous non-operative treatment partly due to therapeutic effect of lymphography, while surgical intervention could be a good option for patients having localized lymphatic etiology.

The expression of Aurora B in normal endometria and endometrial carcinomas and its relation with clinicopathologic parameters of endometrial carcinomas were investigated. Streptavidin-biotin peroxidase (SP) immunohistochemical technique was used to detect the expression of Aurora B in 10 cases of normal proliferative phase endometria, 10 cases of normal secretory phase endometria and 72 cases of endometrial carcinomas respectively. According to the 1988 International Federation of Gynecology and Obstetrics (FIGO) grade, there were 37 patients in grade 1, 23 in grade 2 and 12 in grade 3 respectively. According to the FIGO stage, there were 59 patients in stage I-II and 13 patients in stage III-IV. Aurora B was expressed in both normal proliferative phase endometria, secretory phase endometria and endometrial carcinomas, but its positive labeling index (PLI) in proliferative phase endometria was significantly higher than that in secretory phase endometria (P<0.01) and endometrial carcinomas (P<0.01). The PLI of Aurora B was lower in tumors with well differentiation (G(1)), low surgical staging (I-II), and 1/2 myometrial invasion (all P<0.01). Aurora B exerts its functions in the replication of normal endometrial glandular cells; Expression of Aurora B is significantly correlated with biologic behavior of endometrial carcinoma, indicating that Aurora B may be a promising prognostic factor in endometrial carcinoma.
