Objective:To explore a simple emergency management method for elderly patients with sigmoid volvulus.Methods:The clinical data of 22 elderly patients (>70 years) with sigmoid volvulus from January 2020 to March 2024 in the Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. All patients were treated with a self-made simple closed-loop enema decompression kit. The abdominal circumference, white blood cell count and C-reactive protein (CRP) before treatment and 12 h after tube placement were measured. The patients were followed for 3 months, and the recurrence was recorded. The key indexes on recurrence, including age, American Society of Anesthesiologists (ASA) classification and procedure time, were compared. Pearson correlation analysis was used to examine the relationship between age, procedure time, pain level and gas/stool output within 30 min after tube placement.Results:All 22 patients successfully underwent transanal tube decompression. The procedure time ranged from 1 to 15 min. The gas and stool output within 30 min after tube placement was 600 to 2 100 ml, The rectal tube was retained for 2 to 6 d. Compared with before treatment, the abdominal circumference, white blood cell count and CRP 12 h after tube placement were significantly lower: (85.9 ± 9.6) cm vs. (94.5 ± 10.2) cm, (9.2 ± 2.1) ×10 9/L vs. (11.4 ± 2.5) ×10 9/L and (27.8 ± 22.6) mg/L vs. (46.2 ± 38.9) mg/L, and there were statistical differences ( P<0.01). Four patients underwent elective surgery, while 18 were discharged smoothly after tube removal. No death occurred within 1 month after treatment. Five patients experienced recurrence 3 months after treatment, all were successfully retreated using the same method and discharged. There were no statistical differences in recurrence rates between aged ≥80 years and aged < 80 years patients, ASA class ≥ Ⅳ and ASA class Ⅲ patients, or procedure times ≤5 min and procedure times >5 min patients ( P>0.05). The gas/stool output within 30 min after tube placement was positively correlated with pain level (moderate/severe vs. mild) before tube placement ( r = 215.50, P = 0.015), but showed no significant correlation with age or procedure time ( P>0.05). Conclusions:The self-made simple closed-loop enema decompression kit provides a straightforward, economical and minimally invasive emergency treatment method for elderly patients with sigmoid volvulus. For patients at very high surgical risk, this kit can achieve decompression and volvulus reposition, even in cases of recurrence.

Objective:To investigate the clinical value of right-sided overlap and single-flap valvuloplasty (ROSF) in Da Vinci robotic proximal gastrectomy.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 12 patients who underwent ROSF in Da Vinci robotic proximal gastrectomy at The Affiliated Hospital of Xuzhou Medical University from September 2023 to May 2024 were collected. There were 7 males and 5 females, aged 62(range, 35?75)years. Observation indicators: (1) surgical conditions; (2) postoperative pathological results; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and mea-surement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers. Results:(1) Surgical conditions. All patients successfully completed the surgery, without conversion to laparotomy. The operation time of 12 patients was (236±24)minutes. The time of single-layer fabrication and anastomosis was (105±28)minutes. The volume of intra-operative blood loss was (36±19)mL. Time to postoperative first fluid food intake was (3.5±1.1)days. The amylase levels in the abdominal drainage fluid on postoperative days 1, 2, and 3 were (321±121)U/L, (225±97)U/L, and (85±22)U/L, respectively. Time to postoperative drainage tube removal was (5.3±1.5)days. Duration of postoperative hospital stay was (7.6±1.1)days. All 12 patients had no anasto-motic related complications such as anastomotic leakage, anastomotic bleeding, anastomotic stenosis, and had no functional complications such as gastric emptying disorders or gastroesophageal reflux after surgery. (2) Postoperative pathological results. The distance of the proximal tumor margin of the 12 patients was (1.8±1.1)cm. The distance of distal margin was (5.7±2.1)cm. Number of lymph node dissected was 31.0(range, 22.0?45.0). Number of positive lymph node dissected was 3.4±2.4. Number of lymph node dissected from the pancreatic superior margin was 14.7±4.3. Results of postoperative pathological examination in the 12 patients showed 8 cases of Ⅰ stage, 3 cases of Ⅱ stage, 1 case of Ⅲ stage of the TNM staging. (3) Follow-up. All 12 patients were followed up for 6 (range, 3?24)months. During the follow-up period, all 12 patients had no local tumor recurrence or distant metastasis. All 12 patients had no complications such as anastomotic leakage, anastomotic bleeding, or anastomotic stenosis, and did not experience symptoms of gastroesophageal reflux such as heartburn or vomiting.Conclusion:The ROSF in Da Vinic robotic proximal gastrectomy is safe and feasible.

The aim of this study is to identify the cause of death of a South China tiger cub at the Meihuashan breeding institute of Fujian Province.Pathogenic bacteria were isolated and cultured from liver,spleen,lung and other tissue samples of the dead South China tiger aseptically.The iso-lated bacteria were identified through morphological observation,biochemical characterization,sequence analysis of housekeeping gene gyrB,virulence gene detection,animal pathogenicity test and drug sensitivity test.A pathogenic Aeromonas hydrophila strain,designated FJ/Tiger-201809 was successfully isolated from the trachea of dead South China tiger.The nucleotide sequence ho-mology between the isolate and 11 strains of Aeromonas gyrB ranged from 91.2％to 99.1％,with the highest homology of 99.1％observed with Aeromonas hydrophila(AF208251.1).Genetic evo-lution analysis showed that the isolated strain FJ/Tiger-201809 was in the same evolutionary branch as other reference strains of Aeromonas hydrophila and was closely related.The pathoge-nicity test in mice showed artificial infection of mice with the strain resulted in varying degrees of lesions in several organs of the mice,and the median lethal dose(LD50)was 1 × 107.8 CFU/mL.Virulence gene test results showed that the isolate FJ/Tiger-201809 carried two virulence genes,aer and act.The results of drug sensitivity test showed that FJ/Tiger-201809 was highly sensitive to enrofloxacin and ampicillin among 18 commonly used antibiotics,relatively sensitive to penicil-lin G and doxycycline,and resistant to the other 14 antibiotics.In conclusion,this study isolated and identified a strain of Aeromonas hydrophila from a dead South China tiger with multiple drug resistance and strong pathogenicity,which provided an important reference for the prevention and control of bacterial diseases in South China tiger.

ObjectiveTo evaluate the effect of Tripterygium wilfordii polyglycoside tablets （TWPT） combined with conventional synthetic disease-modifying antirheumatic drugs （csDMARDs） including methotrexate （MTX） and/or leflunomide （LEF） on autoantibodies in rheumatoid arthritis （RA） patients. MethodPubMed， EMBASE， Web of Science， Cochrane Library， China National Knowledge Infrastructure （CNKI）， VIP， Wanfang Data， and China Biomedical Literature Service System （SinoMed） were searched for randomized controlled trials （RCTs） of TWPT combined with MTX and/or LEF in the treatment of RA patients from database inception to December 1， 2021. Primary outcome indicators included rheumatoid factor （RF） and anti-citrullinated protein antibody （ACPA）， and secondary outcome indicators included immunoglobulin （IgA， IgG， and IgM） and adverse drug events （ADE）. ResultThirty-one RCTs， involving 2 643 adult patients， were included， including 20 RCTs of TWPT combined with MTX， 10 of TWPT combined with LEF， and one of TWPT combined with MTX and TWPT. The follow-up time ranged from two weeks to 13 months. Compared with csDMARDs alone， TWPT combined with other drugs significantly improved serum RF of RA patients ［SMD=-2.45， 95% CI ［-2.97， -1.93］， P<0.000 01］， anti-CCP ［SMD=-1.41， 95% CI （-2.35， -0.48）， P=0.003］， IgM ［SMD=-1.90， 95% CI （-3.03， -0.76）， P=0.001］， and IgA ［SMD=-1.18， 95% CI （-2.23， -0.12）， P=0.03］. There were no significant effects on IgG ［SMD=-1.02， 95% CI （-2.04， 0.01）， P=0.05］ and ADE ［RR=0.87， 95% CI （0.66， 1.15）， P=0.32］. ConclusionThe results of this study show that compared with csDMARDs alone， TWPT combined with csDMARDs can effectively improve the levels of autoantibodies in RA patients without increasing the incidence of ADE. However， due to the limited quality and quantity of the included RCTs， the relevant conclusions are only used as a reference for the clinical diagnosis and treatment of RA， and more high-quality studies are still needed to further confirm their efficacy.

Endovascular treatment is a standard treatment regimen for patients with acute ischemic stroke caused by large vessel occlusion. The anesthetic strategy for patients with acute ischemic stroke undergoing endovascular treatment includes local anesthesia, conscious sedation, and general anesthesia. However, the optimal anesthetic strategy for patients with acute ischemic stroke undergoing endovascular treatment is controversial.

Insomnia symptom is one of the most common types of sleep disturbances.Apart from being a risk factor for psychiatric disorders, insomnia symptom has been found to affect the course of psychiatric disorders and increase the relapse rate of psychiatric disorders.Therefore, insomnia treatment is beneficial to mitigate the psychiatric symptoms among chronic insomnia patients, which may help prevent mental health disorders.On the other hand, insomnia treatment for psychiatric patients is conductive to reduce the harm consequence in social function, which can help improving the prognosis of psychiatric disorders.Cognitive behavior therapy for insomnia (CBT-I) is a first-line treatment for chronic insomnia.This paper reviews the research progress on the efficiency of CBT-I on the psychiatric symptoms of chronic insomnia patients, as well as its application in comorbid psychiatric conditions.Findings from previous research suggested that CBT-I is effective to improve the psychiatric symptoms of insomnia patients through insomnia improvement, and it can also promote the remission of depression and anxiety symptoms, reduce the risk of substance disorder and suicide behaviors, and reduce the impairment of life quality and costs of treatment through insomnia improvement among psychiatric patients comorbid with insomnia, which indicated that CBT-I is a safe and effective treatment for insomnia symptoms in psychiatric patients.Moreover, this paper listed the contraindications and the decision-to-treat algorithm of CBT-I among psychiatric patients, as well as the CBT-I availability and adherence that limited the clinical application.More understanding of CBT-I is beneficial to provide support for a broad clinical application in mental health services.
