Ulcerative colitis(UC) is a recurrent, chronic, nonspecific inflammatory bowel disease. The longer the course of the disease, the higher the risk of cancerization. In recent years, the incidence and mortality rates of colon cancer in China have been increasing year by year, seriously threatening the life and health of patients. Therefore, studying the mechanism of "inflammation cancer transformation" in UC and conducting early intervention is crucial. The "Kenang" theory is an important component of traditional Chinese medicine(TCM) theory of phlegm and blood stasis. It is based on the coexistence of phlegm and blood stasis in the body and deeply explores the pathogenic syndromes and characteristics of phlegm and blood stasis. Kenang is a pathological product formed when long-term Qi stagnation leads to the internal formation of phlegm and blood stasis, which is hidden deep within the body. It is characterized by being hidden, progressive, and difficult to treat. The etiology and pathogenesis of "inflammation cancer transformation" in UC are consistent with the connotation of the "Kenang" theory. The internal condition for the development of UC "inflammation cancer transformation" is the deficiency of healthy Qi, with Qi stagnation being the key pathological mechanism. Phlegm and blood stasis are the main pathogenic factors. Phlegm and blood stasis accumulate in the body over time and can produce cancer toxins. Due to the depletion of healthy Qi and a weakened constitution, the body is unable to limit the proliferation and invasion of cancer toxins, eventually leading to cancer transformation in UC. In clinical treatment, the focus should be on removing phlegm and blood stasis, with syndrome differentiation and treatment based on three basic principles: supporting healthy Qi to strengthen the body's foundation, resolving phlegm and blood stasis to break up the Kenang, and regulating Qi and blood to smooth the flow of energy and resolve stagnation. This approach helps to dismantle the Kenang, delay, block, or even reverse the cancerization process of UC, reduce the risk of "inflammation cancer transformation", improve the patient's quality of life, and provide new perspectives and strategies for early intervention in the development of colon cancer.

ObjectiveThis study aimed to observe the impact of sinomenine hydrochloride on the proliferation of fibroblasts and the mRNA expression of related genes in knee joint adhesion and contracture in rabbits. Additionally, we sought to explore its potential mechanisms in combating knee joint adhesion and contracture. MethodsFibroblasts were cultured in vitro, and experimental groups with varying concentrations of sinomenine hydrochloride were established alongside a control group. Cell proliferation was assessed using the CCK-8 assay. Changes in the mRNA expression of fibroblast-related genes following sinomenine hydrochloride treatment were evaluated using RT-qPCR. The impact of the drug on serum levels of inflammatory cytokines was determined using the ELISA method, and the expression of related proteins was assessed using Western blot. ResultsSinomenine hydrochloride was found to inhibit fibroblast viability, with viability decreasing as the concentration of sinomenine hydrochloride increased. The effects of sinomenine hydrochloride in all experimental groups were highly significant (P<0.05). At the mRNA expression level, compared to the control group, sinomenine hydrochloride led to a significant downregulation of inflammatory cytokines in all groups (P<0.05). Additionally, the expression levels of apoptosis-related proteins significantly increased, while Bcl-2 mRNA expression decreased (P<0.05). The mRNA expression levels of the PI3K/mTOR/AKT3 signaling pathway also decreased (P<0.05). At the protein expression level, in comparison to the control group, the levels of inflammatory cytokines IL-6, IL-8, IL-1β, and TGF-β were significantly downregulated in the middle and high-dose sinomenine hydrochloride groups (P<0.05). The expression levels of cleaved-PARP, cleaved caspase-3/7, and Bax increased and were positively correlated with the dose, while the expression levels of the anti-apoptotic protein Bcl-2 and the PI3K/AKT3/mTOR signaling pathway were negatively correlated with the dose. Sinomenine hydrochloride exhibited a significant inhibitory effect on the viability of rabbit knee joint fibroblasts, which may be associated with the downregulation of inflammatory cytokines IL-6, IL-8, and IL-1β, promotion of apoptosis-related proteins cleaved-PARP, cleaved caspase-3/7, and Bax, suppression of Bcl-2 expression, and inhibition of gene expression in the downstream PI3K/AKT3/mTOR signaling pathway. ConclusionSinomenine hydrochloride can inhibit the inflammatory response of fibroblasts in adhesive knee joints and accelerate fibroblast apoptosis. This mechanism may offer a novel approach to improving and treating knee joint adhesion.

BACKGROUND:Previous studies have confirmed that the new compound cottonrose hibiscus leaf gel plaster has a good effect in the treatment of acute soft tissue swelling. OBJECTIVE:To observe the clinical efficacy of compound cottonrose hibiscus leaf gel plaster in the treatment of synovitis of the knee joint. METHODS:Seventy-two patients with knee synovitis were selected from Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from December 2019 to May 2021.These patients were randomly divided into a trial group and a control group,with 36 cases in each group.The trial group was treated with compound cottonrose hibiscus leaf gel plaster,once a day,12 hours each time,while the control group was treated with Diclofenac Diethylamine Emulgel,twice a day.After 28 days of treatment,visual analog scale score,WOMAC Osteoarthritis Index score,quality of life score(SF-36),thickness of knee synovium and comprehensive curative effect were compared between the two groups. RESULTS AND CONCLUSION:(1)Visual analog scale scores after treatment were lower than those before treatment(P<0.05).Visual analog scale scores in the trial group after 7,14 and 28 days of treatment were lower than those in the control group(P<0.05).The WOMAC Osteoarthritis Index scores of the two groups after treatment were lower than those before treatment(P<0.05),and the WOMAC Osteoarthritis Index scores in the trial group after 7,14 and 28 days of treatment were lower than those in the control group(P<0.05).(3)The SF-36 quality of life score in the two groups after 28 days of treatment was higher than that before treatment(P<0.05).SF-36 quality of life score in the trial group after 28 days of treatment was higher than that in the control group(P<0.05).(4)After 28 days of treatment,the thickness of knee synovium in the trial group was less than that in the control group(P<0.05),and the effective rate in the trial group was higher than that in the control group(P<0.05).(5)These findings indicate that compared with Diclofenac Diethylamine Emulgel,the compound cottonrose hibiscus leaf gel plaster can better relieve knee pain,enhance knee joint function,reduce synovial hyperplasia,and elevate the overall quality of life of patients.

Objective The leptin receptor,encoded by the LEPR gene,is involved in tumorigenesis.A potential functional variant of LEPR,rs1137101(Gln223Arg),has been extensively investigated for its contribution to the risk of digestive system(DS)cancers,but results remain conflicting rather than conclusive.Here,we performed a case-control study and subsequent meta-analysis to examine the association between rs1137101 and DS cancer risk. Methods A total of 1,727 patients with cancer(gastric/liver/colorectal:460/480/787)and 800 healthy controls were recruited.Genotyping of rs1137101 was conducted using a polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)assay and confirmed using Sanger sequencing.Twenty-four eligible studies were included in the meta-analysis. Results After Bonferroni correction,the case-control study revealed that rs1137101 was significantly associated with the risk of liver cancer in the Hubei Chinese population.The meta-analysis suggested that rs1137101 is significantly associated with the risk of overall DS,gastric,and liver cancer in the Chinese population. Conclusion The LEPR rs1137101 variant may be a genetic biomarker for susceptibility to DS cancers(especially liver and gastric cancer)in the Chinese population.

Objective:To carry out the policy diffusion analysis of centralized and volume-based drug procurement in China in recent years,and to provide reference for the formulation of centralized and volume-based drug procurement policy.Methods:Through the official websites of the central and provincial governments,the official websites of the Health Commission and the official websites of the Medical Security Bureau,the policy documents related to centralized and volume-based drug procurement from January 1,2009 to December 31,2023 were searched.Based on the policy diffusion theory,the reference network analysis method is used to analyze the intensity,breadth and speed of policy diffusion,and the sequential analysis method of policy keywords is used to analyze the direction of policy diffusion.Results:In the two stages of the development of centralized and volume-based drug procurement policy,the number of policies issued in the medical insurance management stage reached the peak;The top ten policies with the highest diffusion intensity and breadth are all central policies,and most of them are notices and opinions.In addition,the newly promulgated policies have a faster diffusion speed.In the direction of diffusion,top-down and parallel diffusion trends are obvious.Conclusion:The diffusion of centralized and volume-based drug procurement policy in China focuses on the central policy,and the diffusion speed is increasing year by year.It is suggested to strengthen the policy coordination between the central and local governments,establish a unified national information platform for centralized drug procurement,optimize the learning and competition mechanism between governments at all levels,and give play to the advantages of"policy experiment".

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective     To investigate the safety and feasibility of day surgery for patients with palmar hyperhidrosis based on the principles of enhanced recovery after surgery (ERAS). Methods     We retrospectively reviewed the medical records of consecutive patients who underwent endoscopic thoracic sympathicotomy (ETS) in the First Affiliated Hospital of Xi'an Jiaotong University from March 2020 to December 2021. Patients were divided into a day surgery group and a conventional group according to their perioperative management methods. The patients in the day surgery group underwent an optimized perioperative procedure under the guidance of ERAS, and were ventilated with a laryngeal or face mask during the operation. The patients in the conventional group completed the preoperative examination, operation and postoperative observation according to the conventional procedures, and were intubated with a single-lumen endotracheal tube. The demographic characteristics, operation time, hospital stay, postoperative complications, and hospitalization cost were compared between the two groups. Results     Finally 172 patients were collected, including 90 males and 82 females, with an average age of 25.97±7.43 years. There were 86 patients in each group. All patients ceased suffering from palmar sweating after surgery. No patient experienced massive bleeding or conversion to thoracotomy. There was no statistical difference in operation time between the two groups (P=0.534). Patients in the day surgery group were discharged within 24 hours. The average hospital stay in the conventional group was 2.09±0.41 days. Incidence of postoperative respiratory complications, and the hospitalization cost of the day surgery group were significantly lower than those of the conventional group (P<0.001). The satisfaction rate in both groups was greater than 95%. Conclusion     Day surgery for patients with palmar hyperhidrosis based on the principles of ERAS is safe and feasible, which can reduce postoperative complications, shorten the length of hospital stay and save the cost of hospitalization.
