Objective:To explore the application effect of preoperative autologous blood localization method in laparoscopic resection of gastric stromal tumors in unfavorable areas of the stomach.Methods:A retrospective analysis was conducted on the case data of 40 patients with gastric stromal tumors in unfavorable locations admitted to Jinjiang Hospital from January 2019 to December 2022. The patients were divided into a control group (intraoperative endoscopic localization method) and an autologous blood localization group according to different intraoperative lesion localization methods, with 20 cases in each group. The surgical time, intraoperative blood loss, hospitalization time, postoperative exhaust time, and adverse reactions were compared between the two groups.Results:The surgery time of the autologous blood localization group was shorter than that of the control group [(92.30±8.80)min vs (108.20±14.87)min, P<0.05]. There was no statistically significant difference in intraoperative bleeding, hospitalization time, and postoperative exhaust time between the two groups (all P>0.05). Two groups of patients did not show an increase in inflammatory indicators such as white blood cells and C-reactive protein on the day after surgery. Both groups of patients did not experience adverse reactions such as fever, abdominal pain, or postoperative complications. Conclusions:The autologous blood injection localization method provides a safe, simple, and effective method for preoperative localization of gastric stromal tumors in unfavorable areas of the stomach under laparoscopy, and is worthy of clinical promotion and use.

Purpose:
Gastric cancer (GC) is among the deadliest malignancies and the third leading cause of cancer-related deaths worldwide. Galectin-1 (Gal-1) is a primary protein secreted by cancer-associated fibroblasts (CAFs); however, its role and mechanisms of action of Gal-1 in GC remain unclear. In this study, we stimulated GC cells with exogenous human recombinant galectin-1 protein (rhGal-1) to investigate its effects on the proliferation, migration, and resistance to cisplatin.
Materials and Methods:
We used simulated rhGal-1 protein as a paracrine factor produced by CAFs to induce GC cells and investigated its promotional effects and mechanisms in GC progression and cisplatin resistance. Immunohistochemical (IHC) assay confirmed that Gal-1 expression was associated with clinicopathological parameters and correlated with the expression of neuropilin-1 (NRP-1), c-JUN, and Wee1.
Results:
Our study reveals Gal-1 expression was significantly associated with poor outcomes.Gal-1 boosts the proliferation and metastasis of GC cells by activating the NRP-1/C-JUN/ Wee1 pathway. Gal-1 notably increases GC cell resistance to cisplatin The NRP-1 inhibitor, EG00229, effectively counteracts these effects.
Conclusions
These findings revealed a potential mechanism by which Gal-1 promotes GC growth and contributes to chemoresistance, offering new therapeutic targets for the treatment of GC.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common and non-lethal urological condition with painful symptoms. The complexity of CP/CPPS’s pathogenesis and lack of efficient etiological diagnosis results in incomplete treatment and recurrent episodes, causing long-term mental and psychological suffering in patients. Recent findings indicate that the autonomic nervous system involves in CP/CPPS, including sensory, sympathetic, parasympathetic, and central nervous systems. Neuro-inflammation and sensitization of sensory nerves lead to persistent inflammation and pain. Sympathetic and parasympathetic alterations affect the cardiovascular and reproductive systems and the development of prostatitis. Central sensitization lowers pain thresholds and increases pelvic pain perception in chronic prostatitis. Therefore, this review summarized the detailed processes and mechanisms of the critical role of the autonomic nervous system in developing CP/CPPS.Furthermore, it describes the neurologically relevant substances and channels or receptors involved in this process, which provides new perspectives for new therapeutic approaches to CP/CPPS.

BACKGROUND:
LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.
METHODS:
We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.
RESULTS:
On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).
CONCLUSION:
LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.

Objective:To explore the value and advantages of perioperative nutritional support in enhanced recovery after surgery (ERAS).Methods:The clinical data of patients admitted to Jinjiang City Hospital for acute abdomen and undergoing surgery from April 2018 to January 2021 were collected. They were divided into two groups: the enhanced recovery after surgery group (ERAS group, 78 cases) and the traditional perioperative management group (CPM group, 75 cases). The nutritional risk assessment of NRS2002 was performed on admission to the two groups. The postoperative inflammatory indexes, nutrition and rehabilitation related indexes were compared between the two groups.Results:There was no significant difference in preoperative NRS 2002 score, operation method, operation time and blood loss between ERAS group and CPM group ( P>0.05). There was no significant difference in C-reactive protein (CRP), albumin (Alb) and prealbumin (PA) between ERAS group and CPM group before operation ( P>0.05). The ALb and PA of the two groups on the first day after operation were significantly lower than those before operation, and the CRP levels on the first, third, fifth and seventh day after operation were higher than those before operation( P<0.05), with significant difference. The CRP level of ERAS group was lower than that of CPM group on the third day after operation, with significant difference ( P<0.05). On the 7th day after operation, the levels of Alb and PA in ERAS group were higher than those in CPM group ( P<0.05). The recovery time of gastrointestinal function and hospitalization days in ERAS group were significantly reduced, and the total cost of hospitalization was significantly less than that in CPM group ( P<0.05). Conclusions:Perioperative effective nutritional support is helpful to accelerate the recovery of patients with acute abdomen. The application of enhanced recovery after surgery can effectively improve the nutritional status of patients with acute abdomen, reduce the incidence of complications and improve the clinical outcome of patients.

Objective:To explore the relationship between the level of C-reactive protein/serum albumin ratio (CAR) and early postoperative anastomotic leakage in patients with colorectal cancer.Methods:From September 2016 to September 2019, all colorectal cancer patients who were treated in gastrointestinal surgery of Jinjiang hospital in Fujian Province were collected for retrospective analysis. The baseline data of the patients were collected. The blood C-reactive protein (CRP), procalcitonin (PCT) and serum albumin (ALB) were monitored on the first, third, fifth and seventh days after operation, and the results were statistically analyzed.Results:There was no significant difference in baseline data such as age, body mass index (BMI), operation time and intraoperative hemorrhage between the anastomotic leakage group and the non anastomotic leakage group ( P>0.05), but the hospitalization time of the anastomotic leakage group was longer than that of the non anastomotic leakage group ( P<0.05). The CRP level on the 3rd and PCT level on the 5th day after operation in the anastomotic leakage group were higher than those in the non anastomotic leakage group, with significant difference ( P<0.05). The CAR value on the 3rd and 5th day after operation in the anastomotic leakage group was higher than those in the non anastomotic leakage group with significant difference ( P<0.05). Conclusions:CAR can predict early anastomotic leakage in patients with colorectal cancer.
