BACKGROUND Increasing data indicated that long noncoding RNAs(lncRNAs)were directly or indirectly involved in the occurrence and development of tumors,including hepatocellular carcinoma(HCC).Recent studies had found that the expression of lncRNA HAND2-AS1 was downregulated in HCC tissues,but its role in HCC progression is unclear.Ultrasound targeted microbubble destruction mediated gene transfection is a new method to overexpress genes.AIM To study the role of ultrasound microbubbles(UTMBs)mediated HAND2-AS1 in the progression of HCC,in order to provide a new reference for the treatment of HCC.METHODS In vitro,we transfected HAND2-AS1 siRNA into HepG2 cells by UTMBs,and detected cell proliferation,apoptosis,invasion and epithelial-mesenchymal transition(EMT)by cell counting kit-8 assay,flow cytometry,Transwell invasion assay and Western blotting,respectively.In addition,we transfected miR-837-5p mimic into UTMBs treated cells and observed the changes of cell behavior.Next,the UTMBs treated HepG2 cells were transfected together with miR-837-5p mimic and tissue inhibitor of matrix metalloproteinase-2(TIMP2)overexpression vector,and we detected cell proliferation,apoptosis,invasion and EMT.In vivo,we established a mouse model of subcutaneous transplantation of HepG2 cells and observed the effect of HAND2-AS1 silencing on tumor formation ability.RESULTS We found that UTMBs carrying HAND2-AS1 restricted cell proliferation,invasion,and EMT,encouraged apoptosis,and HAND2-AS1 silencing eliminated the effect of UTMBs.Additionally,miR-873-5p targets the gene HAND2-AS1,which also targets the 3’UTR of TIMP2.And miR-873-5p mimic counteracted the impact of HAND2-AS1.Further,miR-873-5p mimic solely or in combination with pcDNA-TIMP2 had been transformed into HepG2 cells exposed to UTMBs.We discovered that TIMP2 reversed the effect of miR-873-5p mimic caused by the blocked signalling cascade for matrix metalloproteinase(MMP)2/MMP9.In vivo results showed that HAND2-AS1 silencing significantly inhibited tumor formation in mice.CONCLUSION LncRNA HAND2-AS1 promotes TIMP2 expression by targeting miR-873-5p to inhibit HepG2 cell growth and delay HCC progression. 展开更多

Laparoscopically assisted colorectal procedures are time-consuming and technically demanding and hence have a long steep learning curve. In the technical demand, surgeons need to handle a long mobile organ, the colon, and have to operate on multiple abdominal quadrants, most of the time with the need to secure multiple mesenteric vessels. Therefore, a new surgical innovation called hand-assisted laparoscopic surgery (HALS) was introduced in the mid 1990s as a useful alternative to totally laparoscopic procedures. This hybrid operation allows the surgeon to introduce the non-dominant hand into the abdominal cavity through a special hand port while maintaining the pneumoperitoneum. A hand in the abdomen can restore the tactile sensation which is usually lacking in laparoscopic procedures. It also improves the eye-to-hand coordination, allows the hand to be used for blunt dissection or retraction and also permits rapid control of unexpected bleeding. All of those factors can contribute tremendously to reducing the operative time. Moreover, this procedure is also considered as a hybrid procedure that combines the advantages of both minimally invasive and conventional open surgery. Nevertheless, the exact role of HALS in colorectal surgery has not been well defined during the advanced totally laparoscopic procedures. This article reviews the current status of hand-assisted laparoscopic colorectal surgery as a minimally invasive procedure in the era of laparoscopic surgery. 展开更多

AIM:To describe the learning curves of hand-assisted laparoscopic D2 radical gastrectomy(HALG) for the treatment of gastric cancer.METHODS:The HALG surgical procedure consists of three stages:surgery under direct vision via the port for hand assistance,hand-assisted laparoscopicsurgery,and gastrointestinal tract reconstruction.According to the order of the date of surgery,patients were divided into 6 groups(A-F) with 20 cases in each group.All surgeries were performed by the same group of surgeons.We performed a comprehensive and indepth retrospective comparative analysis of the clinical data of all patients,with the clinical data including general patient information and intraoperative and postoperative observation indicators.RESULTS:There were no differences in the basic information among the patient groups(P > 0.05).The operative time of the hand-assisted surgery stage in group A was 8-10 min longer than the other groups,with the difference being statistically significant(P = 0.01).There were no differences in total operative time between the groups(P = 0.30).Postoperative intestinal function recovery time in group A was longer than that of other groups(P = 0.02).Lengths of hospital stay and surgical quality indicators(such as intraoperative blood loss,numbers of detected lymph nodes,intraoperative side injury,postoperative complications,reoperation rate,and readmission rate 30 d after surgery) were not significantly different among the groups.CONCLUSION:HALG is a surgical procedure that can be easily mastered,with a learning curve closely related to the operative time of the hand-assisted laparoscopic surgery stage. 展开更多

BACKGROUND Hand-assisted laparoscopic splenectomy(HALS) can help overcome the drawbacks of laparoscopic splenectomy(LS) while maintaining its advantages.AIM To evaluate the efficacy and advantages of HALS for splenomegaly.METHODS The relevant literature was reviewed using the PubMed, EMBASE, Cochrane,Ovid Medline, and Wanfang databases to compare the clinical outcomes of HALS and LS. Odds ratios or mean differences were calculated with 95% confidence intervals for fixed-effects and random-effects models. Overall, 754 patients from16 trials who met the inclusion criteria were selected.RESULTS In pure splenectomy, blood loss volume(P < 0.001) and conversion rate(P =0.008) were significantly lower in the HALS group than in the LS group.Conversely, for splenomegaly, the operative time(P = 0.04) was shorter and blood loss volume(P < 0.001) and conversion rate(P = 0.001) were significantly lower in the HALS group than in the LS group. However, no significant difference was observed in hospital stay length, blood transfusion, time to food intake, complications, or mortality rate between the two groups. Moreover, in splenectomy and devascularization of the upper stomach(DUS), the operative time(P = 0.04) was significantly shorter and blood loss volume(P < 0.001) andconversion rate(P = 0.05) were significantly lower in the HALS + DUS group than in the LS + DUS group. However, no significant difference was observed in hospital stay length, timing of diet, and complications between the two groups.CONCLUSION HALS is an ideal surgical treatment method for splenomegaly because it can maximize the benefits for patients while maintaining the advantages of LS. 展开更多

Objective: Hand-assisted laparoscopic liver resection has the advantages of open and laparoscopic surgeries.There is still lack of comparison of surgical outcomes between hand-assistied laparoscopic liver resection(HALLR)and open liver resection(OLR). This study compared the surgical outcomes of the two approaches between wellmatched patient cohorts.Methods: Patients who received liver resection during January 2014 and October 2017 in Cancer Hospital,Chinese Academy of Medical Sciences and Peking Union Medical College were included in this retrospective study. Propensity score matching(PSM) was performed to reduce selection bias between the two groups. Operation and short-term surgical outcomes were compared between the well matched groups.Results: During this period, 232 patients with a median age of 55.1 years old received OLR, while 49 patients with a median age of 54.7 years old received HALLR. Compared with HALLR group, OLR group has a higher proportion in male patients(190/232, 81.9% vs. 34/49, 69.4%, P=0.048) and lower albumin(43.2±4.5 vs. 44.8±3.7,P=0.020). After PSM, 49 patients from each group were included in the following analysis. Two groups were well balanced in their baseline characteristics, liver functions, preoperative treatments, abdominal surgery history, and surgical difficulty. None perioperative mortality was observed in both groups. Operation time and postoperative complications were similar in two groups(P=0.935, P=0.056). The HALLR group showed less bleeding amount(177.8±217.1 mL vs. 283.1±225.0 mL, P=0.003) and shorter postoperative stay period(6.9±2.2 d vs. 9.0±3.5 d,P=0.001).Conclusions: We demonstrated that hand-assisted laparoscopic surgery is feasible and safe for liver resection,including some difficult cases. HALLR can provide better bleeding control and faster recovery after surgery. 展开更多
