Article Abstract
Objective: To evaluate the safety, feasibility and the long-term outcomes of laparoscopy-assisted gastrectomy (LAG) for advanced gastric cancer (AGC).
Methods: The clinical and follow-up data of 46 cases after LAG from June 2008 to December 2009 were analyzed, and compared with 85 cases after conventional open gastrectomy (OG) for advanced gastric cancer at the same period at our hospital. The surgical safety, postoperative recovery, complications, radical degree, survival rate were compared.
Result: As compared with OG group, operation time was longer in LATG group ((274 ± 78) min vs. ( 217 ± 41) min, t = 4.635, P = 0.000). Estimated blood loss in the LAG group ((254 ± 112) ml) was significantly less than in the OG group (t = 3.942, P = 0.000). Time to ambulation ((63 ± 16) hours), first flatus ((77 ± 20) hours), resumed liquid diet ((88 ± 15) hours), duration of analgesic medication ((53 ± 20) hours) and postoperative hospital stay ((11.1 ± 4.6) days) were significantly shorter in the LAG group (t = 5.549, 6.508, 9.436, 9.464 and 2.980 respectively, all P < 0.01). The distance of the proximal and distal resection margin were (5.7 ± 1.4) cm and (3.9 ± 1.5) cm in LAG group, (5.8 ± 1.1) cm and (4.7 ± 1.5) cm in OG group respectively, but the difference was not significant. The number of lymph node dissections was also similar, (30.5 ± 10.4) in LAG group and (32.6 ± 12.3) in OG group (t = 0.960, P = 0.339). The incidence of postoperative complications and mortality rate in LAG group (8.7% and 0 respectively) were also lower than in the OG group, with no statistically significant difference (P > 0.05). The mean follow-up was 31.0 months (range 6-48 months), and the cumulative survival of the 2 groups was similar (χ(2) = 1.594, P = 0.207).
Conclusions: Laparoscopy-assisted gastrectomy for advanced gastric cancer is not significantly different with open surgery in surgical safety, radical degree, and survival rate. It is less traumatic and of fewer complications.

Objective: The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture.
Methods: Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation.

Southeast Asia's booming tourism and rapid economic growth create a unique setting to explore the interplay between economic development, tourism, and environmental sustainability. This study examines the complex interplay between tourism expansion, financial development, and environmental sustainability in Southeast Asia, specifically from 2000 to 2023. This research aims to fill gaps in previous studies, particularly within the Association of Southeast Asian Nations (ASEAN) context, and to provide a comprehensive understanding of how tourism and financial growth impact environmental outcomes in this region.

Background: Subtrochanteric proximal femoral fractures are generally treated with cephalomedullary nail fixation. We aimed to compare outcomes of subtrochanteric fracture fixation using a single lag screw (Gamma3 nail, GN) or dual lag screw (INTERTAN nail, IN) device.
Methods: The primary outcome measure was mechanical failure, defined as lag screw cut-out or back-out, nail breakage, or peri-implant fracture.

Immune checkpoint blockers have substantially improved prognosis of melanoma patients, nevertheless, resistance remains a significant problem. Here, intrinsic and extrinsic factors in the tumor microenvironment are discussed, including the expression of alternative immune checkpoints such as lymphocyte activation gene 3 (LAG-3) and T-cell immunoglobulin and mucin domain-containing protein 3 (TIM-3). While most studies focus on immune cell expression of these proteins, we investigated their melanoma cell intrinsic expression by immunohistochemistry in melanoma metastases of 60 patients treated with anti-programmed cell death protein 1 (PD-1) and/or anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) therapy, and correlated it with the expression of potential ligands, RNA sequencing data and clinical outcome.

Background: Cardiovascular disease (CVD) is one of the leading causes of death globally. Yet, further research is required into the relationship between CVD and extreme environmental temperatures. This study aims to explore the association between the incidence of CVD and extreme temperatures, and also to identify susceptible subgroups within the population.
