Objective:To systematically evaluate qualitative research on weight regain experiences in post-bariatric surgery patients and provide insights for targeted weight management interventions.Methods:A comprehensive search was conducted in PubMed, Scopus, CINAHL, China National Knowledge Infrastructure, China Biology Medicine disc, and Wanfang data for qualitative studies on the experiences, perceptions, and feelings of post-bariatric surgery patients regarding weight regain. The search covered all available literature up to December 6, 2023. The 2016 Joanna Briggs Institute critical appraisal tool for qualitative research was used for quality assessment. Data were synthesized using the aggregative integration method.Results:A total of nine studies were included, yielding 17 core themes, which were categorized into five subcategories and further synthesized into two overarching themes: patients' awareness of weight management improved, but knowledge gaps, misconceptions, and inappropriate behaviors persisted; negative experiences were prevalent in the weight management process.Conclusions:The awareness of weight management in post-bariatric surgery patients needs to be strengthened. Healthcare professionals should identify high-risk individuals for weight regain, provide informational and social support, and help patients correct misconceptions and unhealthy behaviors to effectively prevent and manage weight regain.

The present study evaluated the effect of non-thermal plasma on skin wound healing in BalB/c mice. Two 6-mm wounds along the both sides of the spine were created on the back of each mouse (n=80) by using a punch biopsy. The mice were assigned randomly into two groups, with 40 animals in each group: a non-thermal plasma group in which the mice were treated with the non-thermal plasma; a control group in which the mice were left to heal naturally. Wound healing was evaluated on postoperative days (POD) 4, 7, 10 and 14 (n=5 per group in each POD) by percentage of wound closure. The mice was euthanized on POD 1, 4, 7, 10, 14, 21, 28 and 35 (n=1 in each POD). The wounds were removed, routinely fixed, paraffin-embedded, sectioned and HE-stained. A modified scoring system was used to evaluate the wounds. The results showed that acute inflammation peaked on POD 4 in non-thermal plasma group, earlier than in control group in which acute inflammation reached a peak on POD 7, and the acute inflammation scores were much lower in non-thermal group than in control group on POD 7 (P<0.05). The amount of granular tissue was greater on POD 4 and 7 in non-thermal group than in control group (P<0.05). The re-epithelialization score and the neovasularization score were increased significantly in non-thermal group when compared with control group on POD 7 and 10 (P<0.05 for all). The count of bacterial colonies was 10(3) CFU/mL on POD 4 and <20 CFU/mL on POD 7, significantly lower than that in control group (10(9) CFU/mL on POD 4 and >10(12) CFU/mL on the POD 7) (P<0.05). It was suggested that the non-thermal plasma facilitates the wound healing by suppressing bacterial colonization.

Objective To sum up our preliminary experience for the treatment of abdominal aortic aneurysm ( AAA) using unibody bifurcation stent-graft ( UBST). Methods This study included 42 cases, among them there were 39 AAA cases, one case of abdominal aortic pseudoanrurysm (AAPA) , one case of type C dissecting aortic aneurysm, one descending aortic aneurysm (DAA) with AAA. Five stent-grafts were deployed for the case with DAA and AAA including 4 stent-grafts were used for DAA and one UBST for AAA. For the case of type C dissecting aortic aneurysm, one straight stent-graft was used for sealing the proximal intimal tear, one UBST was deployed for sealing the distal intimal tear. A graft bypass was required in the case with AAPA through extraperitoneal incision occlusion of external iliac artery of one side, then an UBST was deployed for sealing the rupture of abdominal aorta. Results The average operative time was 50 minutes. One patient died. One more proximal cuff was required in 8 cases. One more distal cuff was required in one case, one more proximal and distal cuff respectively were required in one case. Postoperative transient slight leakage was present in 8 cases. Both internal iliac arteries were sealed in 5 cases; unilateral internal iliac artery was sealed in 20 cases. Success was reached in two cases with an angle of 90 degress between aneurismal neck and body. Conclusion The exclusion of AAA using UBST is successful and safe.

ObjectiveTo summarize our preliminary result of the management of aneurysm using stent-graft. Method Different types of aneurysm were treated by stent-grafting in 71 cases including dissecting aortic aneurysm in 48 cases,infrarenal abdominal aortic aneurysm in 13 cases,pseudoaneurysm in descending aorta or left subclavian artery or infrarenal abdominal aorta and suprarenal abdominal aorta in 4,1,2 and 1 case(s) respectively,left or right iliac aneurysm in 2 cases respectively. The proximal intimal entry for dissecting aortic aneurysm and rupture site for pseudoaneurysm were sealed. Abdominal aortic aneurysm or iliac aneurysm was excluded using bifurcated or aorto-uni-iliac or straight stent-graft. Results The technique was successful in all cases. Two patients died perioperatively. Slight leakage in the proximal end of the dissecting aortic aneurysm was found in 5 cases,the leakage sealed off in 4 cases half year later. The reflux from distal entry was present in 9 cases. Initial leakage found in 6 cases of the abdominal aortic aneurysm,underwent spontaneous healing in 5 cases when followed-up at 3 months. Conclusion The treatment of dissecting aortic aneurysm,pseudoaneurysm and abdominal aortic aneurysm using stent-graft is mini-invasive and safe,though the long-term efficacy remains to be clarified.
