Immunodeficiency is one of the main clinical phenotypes of diseases caused by germline loss-of-function variants in the nuclear SET domain-containing protein 2 (NSD2)-coding gene. NSD2 gene plays an important regulatory role in the immune system, but the underlying mechanism has not been fully elucidated. In recent years, great progress has been made regarding the function of NSD2 gene in the immune system including involving in B cell differentiation and development, promoting germinal center B cell activation and antibody production, recruiting regulatory T (Treg) cells to the maternal-fetal interface to induce maternal-fetal immune tolerance, and up-regulating MHCⅠ expression in tumor cells to trigger tumor immunity. This article mainly reviews the research progress in the regulatory function of NSD2 gene in the above immune processes.

Objective     To systematically evaluate the safety, efficacy, and economics of intracardiac echocardiography (ICE) versus transesophageal echocardiography (TEE) in left atrial appendage occlusion (LAAO). Methods     PubMed, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Database were systematically  searched to collect relevant studies on comparing ICE and TEE-guided LAAO from inception to June 15th, 2022. Two reviewers independently screened the literatures, extracted the data, and assessed the risk of bias of the included studies. Meta-analyses were performed using RevMan 5.3 and R 4.0.3. Retrospective cohort studies were excluded for sensitivity analysis. Subgroup analyses were performed based on the types of occluder and ICE catheter. Results     A total of 14 studies with 6 599 patients were included. Meta-analyses showed no statistical differences in technical success rate, overall complications, device embolization, peri-device leakage, device-related thrombus, stroke, vascular complications, bleeding, operation time, fluoroscopy time, or contrast agent volume between the ICE and TEE-guided LAAO. The total in-room time (MD=–33.47 min, 95%CI –41.20 to –25.73, P<0.000 01) and radiation dosage (MD=–170.20 mGy, 95%CI –309.79 to –30.62, P=0.02) were lower in the ICE group than those in the TEE group, whereas the incidence of pericardial effusion/tamponade was higher than the TEE group (RR=1.57, 95%CI 1.01 to 2.45, P=0.048). Except for pericardial effusion/tamponade, subgroup analyses and sensitivity analysis showed similar results. The analysis based on the cost data from the United States showed comparable or even lower total costs for ICE versus TEE, but comparative domestic cost studies were lacking. Conclusion     Current evidence suggests that ICE-guided LAAO can reduce radiation dosage and total in-room time, and there is no statistical difference in the overall complication rate between the two groups. Owing to the limitations of sample size and quality of the included studies, the conclusion still needs to be verified by large sample size and high-quality randomized controlled trials.

OBJECTIVEVideo-assisted thoracoscopic (VATS) esophagectomy has been performed for more than 10 years in China. However, compared with the conventional esophagectomy via right thoracotomy, whether VATS esophagectomy has more advantages or not in the lymph node (LN) dissection and prevention of perioperative complications is still controversial and deserves to be further investigated. The aim of this study was to explore whether there are significant differences in this issue between the two surgical modalities or not.

METHODSThe results of lymph node dissection and perioperative complications as well as other parameters in the patients treated by VATS esophagectomy and those by conventional esophagectomy via right thoracotomy at our department from May 1, 2009 to July 30, 2013 were compared using SPSS 16.0 in order to investigate whether there was any significant difference between these two treatment modalities in the learning curve stage of VATS esophagectomy.

RESULTSOne hundred and twenty-nine cases underwent VATS esophagectomy between May 1, 2009 and July 30, 2013, and another part 129 cases with the same preoperative cTNM stage treated by conventional esopahgectomy via right thoracotomy were selected in order to compare the results of lymph node dissection and perioperative complications as well as other parameters between those two groups of patients. There were no significant differences in the sex, age, lesion locations and cTNM stage between these two groups. The total LN metastatic rate in the VATS esophagectomy group was 35.7% and that of the conventional esophagectomy group was 37.2% (P > 0.05). The total average number of dissected lymph nodes was 12.1 vs. 16.2 (P < 0.001). The average dissected LN stations was 3.2 vs. 3.6 (P = 0.038). The total average number of dissected LN along the left recurrent laryngeal nerve was 2.0 vs. 3.7 (P = 0.012). The total average number of dissected LN along the right recurrent laryngeal nerve was 2.9 vs. 3.4 (P = 0.231). However, there was no significant difference in the total average number of dissected LN in the other thoracic LN stations, and in the perioperative complications between the two groups. The total postoperative complication rate was 41.1% in the VATS group versus 42.6% in the conventional group (P = 0.801). The cardiopulmonary complication rate was 25.6% vs. 27.1% (P = 0.777). The death rate was the same in the two groups (0.8%). The VATS group had less blood infusion (23.2% vs. 41.8%, P = 0.001) and shorter hospital stay (15.9 days vs. 19.2 days, P = 0.049) but longer operating time (161.3 min vs. 127.8 min, P < 0.01).

CONCLUSIONSIn the learning curve stage of VATS esophagectomy, compared with the conventional esophagectomy, less LN number and stations can be dissected in the VATS group due to un-skillful VATS manipulation, especially it is more difficult in the LN dissection along the left recurrent laryngeal nerve. Therefore, it is more suitable to select patients with early esophageal cancer without obvious enlarged lymph nodes for VATS esophagectomy in the learning curve stage.

BACKGROUNDIn order to minimize the injury reaction during the surgery and reduce the morbidity rate, hence reducing the mortality rate of esophagectomy, minimally invasive esophagectomy (MIE) was introduced. The aim of this study was to compare the postoperative outcomes in patients with esophageal squamous cell carcinoma undergoing minimally invasive or open esophagectomy (OE).

METHODSThe medical records of 176 consecutive patients, who underwent minimally invasive esophagectomy (MIE) between January 2009 and August 2013 in Cancer Institute & Hospital, Chinese Academy of Medical Sciences, were retrospectively reviewed. In the same period, 142 patients who underwent OE, either Ivor Lewis or McKeown approach, were selected randomly as controls. The clinical variables of paired groups were compared, including age, sex, Charlson score, tumor location, duration of surgery, number of harvested lymph nodes, morbidity rate, the rate of leak, pulmonary morbidity rate, mortality rate, and hospital length of stay (LOS).

RESULTSThe number of harvested lymph nodes was not significantly different between MIE group and OE group (median 20 vs. 16, P = 0.740). However, patients who underwent MIE had longer operation time than the OE group (375 vs. 300 minutes, P < 0.001). Overall morbidity, pulmonary morbidity, the rate of leak, in-hospital death, and hospital LOS were not significantly different between MIE and OE groups. Morbidities including anastomotic leak and pulmonary morbidity, inhospital death, hospital LOS, and hospital expenses were not significantly different between MIE and OE groups as well.

CONCLUSIONSMIE and OE appear equivalent with regard to early oncological outcomes. There is a trend that hospital LOS and hospital expenses are reduced in the MIE group than the OE group.
