Objective To compare the clinical efficacies of totally laparoscopic and laparoscopy-assisted radical total gastrectomies.Methods The retrospective cohort study was conducted.The clinicopathological data of 373 patients with gastric cancer who underwent totally laparoscopic or laparoscopy-assisted radical total gastrectomies from the 7 medical centers in China (82 patients in the Affiliated Hospital of Qinghai University,80 in the Traditional Chinese Medicine Hospital of Guangdong Province,60 in the First Affiliated Hospital of Xiamen University,51 in the Hangzhou First People's Hospital,46 in the First Affiliated Hospital of Xi'an Jiaotong University,30 in the Second Affiliated Hospital of Jilin University and 24 in the Xijing Hospital of the Fouth Military Medical University) between January 2015 and December 2016 were collected.Of 373 patients,the 183 and 190 patients were respectively divided into the totally laparoscopic group (undergoing totally laparoscopic radical total gastrectomy) and laparoscopy-assisted group (undergoing laparoscopy-assisted radical total gastrectomy),including 63 and 19 in the Affiliated Hospital of Qinghai University,36 and 44 in the Traditional Chinese Medicine Hospital of Guangdong Province,25 and 35 in the First Affiliated Hospital of Xiamen University,20 and 31 in the Hangzhou First People's Hospital,10 and 36 in the First Affiliated Hospital of Xi'an Jiaotong University,17 and 13 in the Second Affiliated Hospital of Jilin University,12 and 12 in the Xijing Hospital of the Fouth Military Medical University.Routine five-port method was applied for laparoscopic radical total gastrectomy and D2 lymphadenectomy.Roux-en-Y anastomosis was applied for digestive tract reconstruction,and digestive tract reconstruction was performed under laparoscopy in the totally laparoscopic group and via upper abdominal median incision in the laparoscopy-assisted group.Observation indicators:(1) operation and postoperative situations;(2) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect the postoperative overall survival and tumor recurrence or metastasis up to March 2017.Measurement data with normal distribution were represented as x±s.Comparison between the groups was analyzed by the t test.Measurement data with skewed distribution were represented as M (range).Comparisons of count data were analyzed using the chi-square test and Fisher exact probability.Results (1)Operation and postoperative situations:all the patients in the 2 groups underwent successful operations,without perioperative death.Esophagojejunostomy methods of 183 patients in totally laparoscopic group:conventional circular stapler method were performed in 28 patients,anti-puncture circular staplar method in 6 patients,OrVilTM method in 5 patients,functional end-to-end esophagojejunostomy method in 65 patients and peristalsis side-to-side esophagojejunostomy method in 79 patients.Conventional circular stapler method was applied to 190 patients in the laparoscopy-assisted group.Operation time,time of esophagojejunostomy,length of assisted incision,using time of analgesics and expenses of digestive tract reconstruction were (238± 55)minutes,(29±9)minutes,(5.1 ± 1.1)cm,(2.2±l.0)days,(18 332±2 141)yuan in the totally laparoscopic group and (217±39)minutes,(26±7)minutes,(7.8 ±2.0)cm,(2.7± 0.9)days,(16 237 ± 1 923)yuan in the laparoscopy-assisted group,respectively,with statistically significant differences between the 2 groups (t =4.324,3.455,-16.835,-5.561,9.949,P<0.05).The cases with postoperative overall complications,anastomosis leakage,anastomosis stricture,anastomosis bleeding and expenses of esophagojejunostomy were respectively 24,9,7,5,(9 668±2 814)yuan in the totally laparoscopic group and 24,8,9,6,(9 331 ±2 067)yuan in the laparoscopy-assisted group,with no statistically significant difference between the 2 groups (x2 =0.036,0.107,0.189,0.059,t=1.322,P>0.05).All the patients with postoperative complications were cured by symptomatic treatment.(2) Follow-up and survival situations:of 373 patients,336 were followed up for 4-26 months,with a median time of 13 months,including 166 in the totally laparoscopic group and 170 in the laparoscopy-assisted group.During the follow-up,cases with overall survival,tumor recurrence and tunor metastasis were respectively 150,10,16 in the totally laparoscopic group and 154,9,16 in the laparoscopy-assisted group (10 and 9 patients in the totally laparoscopic and laparoscopy-assisted groups with simutaneous tumor recurrence and metastasis),showing no statistically significant difference between the 2 groups (x2 =0.075,0.010,P>0.05).Conclusions Total laparoscopic and laparoscopyassisted radical total gastrectomies are safe and feasible,with equivalent overall outcomes and effects of esophagojejunostomy.Compared with laparoscopy-assisted radical total gastrectomy,the postoperative pain time of patients in total laparoscopic radical total gastrectomy is less,but there are longer time of esophagojejunostomy and higher expenses of digestive tract reconstruction.

Objective To explore any changes in the patterns of cortical activation after repetitive transcra-nial magnetic stimulation ( rTMS) using functional near-infrared spectroscopy when rTMS is used to treat paralyzed upper limbs. Methods Thirty hemiplegic stroke survivors were randomly divided into a treatment group and a con-trol group, each of 15. Those in the treatment group received 1 Hz rTMS on the M1 area of the unaffected hemisphere for 21 days, while the control group was given sham stimulation. The Fugl-Meyer motor assessment ( FMA-UE) was used to assess the paralyzed upper limbs before the treatment and after 7, 14 and 21 days of treatment. Oxy-hemoglo-bin ( HbO2 ) levels were measured in the premotor cortex, the supplementary motor area and the sensorimotor areas ( SMCs) of the affected and unaffected hemispheres before and after the treatment using the functional near-infrared spectroscopy. Results Before the treatment there was no significant difference between the two groups in their aver-age FMA-UE scores. The average FMA-UE scores of both groups increased significantly after 14 and 21 days of treat-ment, with the average scores at 21 days significantly better than after 14 days for both groups. But after 14 and 21 days the treatment group's average score was significantly better than that of the control group. The average HbO2 level in the SMC area of the unaffected hemisphere in the treatment group had decreased significantly after 21 days of treat-ment, and it was then significantly lower than the same level in the control group. Conclusion Twenty-one days of rTMS of the unaffected hemisphere can decrease cortical activation in the unaffected SMC area and promote the recov-ery of upper limb function.

Objective To determine the utility of computed tomographic (CT) enteroclysis for characterization of the status of the anastomotic site in patients with Crohn's disease (CD) who have previously undergone ileocolic resection. Methods Totally 31 CD patients who had previously undergone ileocolic resection were enrolled in the study. After having been orally administered with isosmotic mannitol, the patients received CT scanning including plain scan, arterial phase scan, and portal venous phase scan. The abnormal CT findings were analyzed based on portal venous phase images. CT enteroclysis findings in 31 patients were evaluated by two radiologists in consensus. Endoscopic findings, histopathologic findings, and/or the Crohn's disease activity index (CDAI) were used as the reference criteria. Associations between CT enteroclysis findings and anastomotic site status were assessed. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CT enteroclysis for the diagnosis of normal anastomosis versus anastomotic recurrence were estimated. Results Twenty-six cases and 5 cases were diagnosed as disease recurrence and normal anastomosis, respectively. In the disease recurrence group, 11 patients (42%) had lymphadenopathy (diameter> 1 cm) and 8 patients (31%) had peri-anastomotic fistulas, which were absent in normal anastomosis group, but the difference was not significant Anastomotic wall thickening more than 6 mm, marked mucosal enhancement, stratification, and peri-anastomotic stranding were found in 16 (62%), 19 (73%), 14 (54%), and 20 (77%) cases, respectively, in disease recurrence group, which were absent in normal anastomosis group ( all P < 0.05 ). When the diagnosis of anastomotic recurrence was based on more than two of the following six variables, including lymphadenopathy, peri-anastomotic fistulas, anastomotic wall thickening more than 6 mm, marked mucosal enhancement, stratification, and peri-anastomotic stranding, its sensitivity, specificity, postive predictive value, negative predictive value, and accuracy yielded 88%, 100%, 100%, 63%, and 90%, respectively. The diagnostic accuracy of anostomotic stenosis with CT was only 53%. Conclusion CT enteroclysis yields objective and relatively specific morphologic criteria that help differentiate between recurrent disease and normal at the anastomotic site after ileocolic resection for CD.

The clinical application of immune checkpoint inhibitors (ICIs) has significantly improved the prognosis of hepatocellular carcinoma (HCC) patients. With the widespread applica-tion of ICIs in HCC, the management of immune-related adverse events (irAE) gained more and more attention. However, the complicated disease characteristics and various combination therapies in HCC throw out challenges to irAE management. Therefore, the editorial board of the 'Chinese expert consensus on the management of immune-related adverse events of hepatocellular carcinoma treated with immune checkpoint inhibitors (2021 edition)' organizes multidisciplinary experts to discuss and formulate this consensus. The consensus focuses on issues related to HCC irAE manage-ment, and puts forward suggestions, in order to improve standardized and safety clinical medication, so as to maximize the benefits of immunotherapy for patients.

The BCCIP (BRCA2- and CDKN1A-interacting protein) is an important cofactor for BRCA2 in tumor suppression. Although the low expression of BCCIP is observed in multiple clinically diagnosed primary tumor tissues such as ovarian cancer, renal cell carcinoma and colorectal carcinoma, the mechanism of how BCCIP is regulated in cells is still unclear. The human INO80/YY1 chromatin remodeling complex composed of 15 subunits catalyzes ATP-dependent sliding of nucleosomes along DNA. Here, we first report that BCCIP is a novel target gene of the INO80/YY1 complex by presenting a series of experimental evidence. Gene expression studies combined with siRNA knockdown data locked candidate genes including BCCIP of the INO80/YY1 complex. Silencing or over-expressing the subunits of the INO80/YY1 complex regulates the expression level of BCCIP both in mRNA and proteins in cells. Also, the functions of INO80/YY1 complex in regulating the transactivation of BCCIP were confirmed by luciferase reporter assays. Chromatin immunoprecipitation (ChIP) experiments clarify the enrichment of INO80 and YY1 at +0.17 kb downstream of the BCCIP transcriptional start site. However, this enrichment is significantly inhibited by either knocking down INO80 or YY1, suggesting the existence of both INO80 and YY1 is required for recruiting the INO80/YY1 complex to BCCIP promoter region. Our findings strongly indicate that BCCIP is a potential target gene of the INO80/YY1 complex.

The precise localization of pulmonary nodules has become an important technical key point in the treatment of pulmonary nodules by thoracoscopic surgery, which is a guarantee for safe margin and avoiding removal of too much normal lung parenchyma. With the development of medical technology and equipment, the methods of locating pulmonary nodules are also becoming less trauma and convenience. There are currently a number of methods applied to the preoperative or intraoperative localization of pulmonary nodules, including preoperative percutaneous puncture localization, preoperative transbronchial localization, intraoperative palpation localization, intraoperative ultrasound localization, and localization according to anatomy. The most appropriate localization method should be selected according to the location of the nodule, available equipment, and surgeon鈥檚 experience. According to the published literatures, we have sorted out a variety of different theories and methods of localization of pulmonary nodules in this article, summarizing their advantages and disadvantages for references.
