PI3K/Akt, Wnt/β-catenin, TGF-β, Nrf2 and Notch signaling pathways are mainly involved in the TCM treatment of chronic refractory wounds (CRW). Chinese materia medica monomers and compound preparations can inhibit protein kinases related to signaling pathways in wound tissue and promote wound healing; reduce the expression of inflammatory factors and inhibit the occurrence of inflammatory response; promote the proliferation and differentiation of growth factors and epidermal stem cells, accelerate the regeneration of granulation tissue, and play a role in repairing wound regeneration.

In humans, the liver is a central metabolic organ with a complex and unique histological microenvironment. Hepatocellular carcinoma (HCC), which is a highly aggressive disease with a poor prognosis, accounts for most cases of primary liver cancer. As an emerging hallmark of cancers, metabolic reprogramming acts as a runaway mechanism that disrupts homeostasis of the affected organs, including the liver. Specifically, rewiring of the liver metabolic microenvironment, including lipid metabolism, is driven by HCC cells, propelling the phenotypes of HCC cells, including dissemination, invasion, and even metastasis in return. The resulting formation of this vicious loop facilitates various malignant behaviors of HCC further. However, few articles have comprehensively summarized lipid reprogramming in HCC metastasis. Here, we have reviewed the general situation of the liver microenvironment and the physiological lipid metabolism in the liver, and highlighted the effects of different aspects of lipid metabolism on HCC metastasis to explore the underlying mechanisms. In addition, we have recapitulated promising therapeutic strategies targeting lipid metabolism and the effects of lipid metabolic reprogramming on the efficacy of HCC systematical therapy, aiming to offer new perspectives for targeted therapy.

Objective To evaluate the regulatory effects of psilocybin on social behavior of male C57BL/6J mice.Methods Adult male C57BL/6J mice were intraperitoneally injected with psilocybin(0.2,1 and 5 mg/kg,i.p.),and the effects of psilocybin on prosocial behavior were evaluated by the three-chamber test.Stressed mice undergoing chronic social defeat stress(CSDS)were given acute intraperitoneal injection of psilocybin(1 mg/kg)to evaluate the moderation of social novelty preference behavior using the modified two-chamber test.Results Intraperitoneal injection of psilocybin(1 mg/kg)promoted prosocial behavior and prolonged social time(P＜0.01),while intraperitoneal injection of psilocybin(0.2 mg/kg)had no apparent effect on the prosocial behavior of mice,and intraperitoneal injection of psilocybin(5 mg/kg)inhibited prosocial behavior before promoting it.Further studies showed that intraperitoneal injection of psilocybin(1 mg/kg)increased the social novelty exploration time in stressed mice undergoing CSDS.Conclusion This study shows that 1 mg/kg dose of psilocybin can promote the prosocial behavior in mice,and potentially ameliorate the deficit of social novelty preference behavior in CSDS mice.

Objective To discuss the clinical application of coronary CT angiography(CCTA)-derived fractional flow reserve(CT-FFR)in evaluating the risk stratification of the coronary artery stenosis and atherosclerotic plaque quantitative parameters.Methods A total of 122 patients,who received CCTA examination at the Xuzhou Municipal Central Hospital of China,were enrolled in this study.The patients were divided into non-ischemia group(CT-FFR＞0.8,n=66)and ischemia group(CT-FFR0.8,n=56).The characteristics of atherosclerotic plaque were compared between the two groups.Logistic regression analysis was used to analyze the correlation between plaque characteristics and ischemic lesions.Results There were 218 vessels having a CT-FFR＞0.8 and 174 vessels having a CT-FFR ≤0.8.Statistically significant differences in the total plaque volume,calcified plaque volume,plaque length,and stenosis ratio＞50％existed between the two groups(all P＜0.05).Logistic regression analysis indicated that the total plaque volume,calcified plaque volume,plaque length,and stenosis ratio＞50％were the risk factors for myocardial ischemia.Conclusion CT-FFR can be used for the risk stratification of coronary stenosis and atherosclerotic plaque characteristics,which can evaluate the local myocardial blood supply condition from the anatomical stenosis and functional level so as to optimize the diagnosis and treatment measures.

Objective:To investigate whether intestinal rehabilitation therapy (IRT)could optimize the effectiveness of IRT in patients with short bowel syndrome (SBS) caused by acute mesenteric ischemia (AMI) with chronic multivessel lesions.Methods:Clinical data of 18 hospitalized patients diagnosed with AMI leading to SBS and undergoing IRT at the Eastern Theater General Hospital of the People's Liberation Army from Jan 2012 to Oct 2023 was retrospectively analyzed.Result:Following IRT, the revascularization group showed significantly greater increases in ASMI and grip strength compared to the control group [(0.28±0.26) kg/m 2vs. (0.02±0.21) kg/m 2, P=0.033, and (0.97±0.33) kg vs. (0.48±0.34) kg, P=0.007, respectively]. Similarly, the increase in EN intake was significantly higher in the revascularization group compared to the control group [(572.5±93.6) ml/d vs. (375.2±176.3) ml/d, P=0.012], accompanied by a greater improvement in intestinal nitrogen absorption rate [(25.06±14.06)% vs. (13.84±4.62)%, P=0.034] and a more substantial decrease in GSRS scores [(-15.88±3.94) vs. (-6.33±5.13), P=0.030]. Moreover, there were significant differences in the composition of EN formulations between the two groups after IRT ( P=0.046). Additionally, SF-36 scores at discharge were significantly higher in the revascularization group than that in the control group for five indicators including BP, GH, VT, SF, and MH ( P<0.05). Conclusions:For patients with SBS resulting from AMI by chronic multivessel lesions, revascularization therapy may not leading to higher growth in weight and hematological nutritional indicators during IRT, but it is beneficial for improving muscle function, improving EN absorption, increasing the likelihood of PN independence, relieving gastrointestinal symptoms, and enhancing overall quality of life.

Objective:To investigate the role of dietary fiber in the intestinal rehabilitation for patients with ultra-short bowel syndrome.Methods:This study included 34 inpatients diagnosed with ultra-short bowel syndrome in the General Surgery Department of the Eastern Theater General Hospital of the People's Liberation Army from January 2012 to October 2023. Patients were grouped based on whether they received intestinal rehabilitation and whether dietary fiber was added to the treatment plan, and were divided into three groups: nutritional therapy group (11 cases), growth hormone + glutamine intestinal rehabilitation treatment group (10 cases) and growth hormone injection + glutamine + dietary fiber intestinal rehabilitation treatment group (13 cases). The therapeutic regimen and its changes, pre- and post-treatment parameters of hematology, nutrition, intestinal absorption, fecal consistency, and quality of life were recorded and compared, and the impact of different treatment regimens on clinical outcomes was analyzed.Results:Compared with nutrition treatment group and growth hormone + glutamine intestinal rehabilitation treatment group, growth hormone injection + glutamine + dietary fiber intestinal rehabilitation treatment group, the increase of enteral nutritional fluid, the decrease of parenteral nutritional energy, the increase of intestinal moisture absorption, the decrease of defecation times and the appreciation of hemoglobin were significantly increased, and the difference was statistically significant ( P<0.05). At the same time, the levels of insulin-like growth factor 1 and insulin-like growth factor binding protein were significantly increased after treatment ( P<0.01). Conclusions:Nutritional support combined with intestinal rehabilitation can significantly improve the nutritional status and intestinal absorption rate of ultra-short bowel syndrome patients. The use of dietary fiber in the intestinal rehabilitation regimen for ultra-short bowel syndrome patients yields more significant benefits, as evidenced by improved clinical outcomes.

Objective To establish a new fermentation process for Zhizhen Recipe by using bi-directional solid fermentation method of traditional Chinese medicine.Methods ① Candidate strains for fermentation were primarily recruited through literature research.Then plate incorporation assay of candidate strains were conducted to investigate the growth compatibility between the strains.CCK-8 cell proliferation assay was used to compare the half proliferation inhibitory concentration of the products obtained under different fermentation conditions against human colorectal cancer cell line HCT-8.The advantages of different fermentation systems were evaluated and the key fermentation parameters including strains and incubation periods were determined,which gave rise to the establishment of the optimal fermentation process for Zhizhen Recipe.② In vitro pharmacological effects were compared between the fermented and unfermented Zhizhen Recipe by measuring proliferation inhibition of HCT-8 cells,as well as NO release and phagocytic activity of RAW264.7 cells.Results The results showed that Aspergillus niger/Saccharomyces cerevisiae was the optimal combination of strains,and the optimal fermentation time is 4 days.Under optimized conditions,the half inhibitory concentration(IC50)of the fermentation group on HCT-8 cells was 67.41 μg·mL-1,while IC50 value of the unfermented Zhizhen Recipe was 1 032 μg·mL-1.Compared with unfermented preparation,the fermented preparation exhibited significant effects on inhibiting the release of inflammatory factor NO of macrophages RAW264.7 cells and obviously enhanced their phagocytic activity.Conclusion In this present study,we established a new bi-directional solid fermentation process for Zhizhen Recipe.Under this fermentation system,the anti-colorectal cancer activity,anti-inflammatory activity and pro-immune activity of Zhizhen Recipe in vitro were significantly improved.

Objective To analyze the secular trends of pancreatic cancer incidence and mortality in Changning district of Shanghai from 1974 to 2013. Methods We calculated the age-standardized rates of incidence and mortality and the average annual percent changes for pancreatic cancer using Segi's world standard population and the data from Shanghai Cancer Registry. Age-period-cohort model was constructed to further assess the effect of age, diagnosis period and birth cohort on the secular trends of pancreatic cancer incidence and mortality. Results During 1974-2013, the age-standardized incidence and mortality rates were 6.49/10⁵ and 6.01/10⁵ in male, 4.83/10⁵ and 4.57/10⁵ in female, respectively. The age-standardized incidence was increased by 0.8% per year in male during past 40 years, while there was no change in mortality. The age-standardized incidence and mortality rates were increased by 1.6% and 1.3% per year in female. After adjusting the effects of diagnosis period and birth cohort, the incidence and mortality rates of pancreatic cancer increased by about 11% every 5 years older in both male and female. Diagnosis period and birth cohort had no statistical impact on the incidence and mortality of pancreatic cancer. Conclusion The age-standardized incidence of pancreatic cancer shows significantly rising trends during 1974-2013 in both male and female in Changning district of Shanghai, as well as the age-standardized mortality in female. The incidence and mortality rates also increase with age.

OBJECTIVE：To establish quantitative e valuation system of the prophylactic use of antibiotics in orthopedic type Ⅰ incision surgery ，and to provide reference for evaluating the rational prevention use of antibiotics in this type surgery scientifically. METHODS：Based on the Guidelines of Clinical Use of Antimicrobial Agents （2015 edition），drug instructions ，related guidelines and references ，experts from relevant departments jointly discussed and formulated the evaluation criteria for the rationality of the use of antibiotics in type Ⅰ incision in orthopedic surgery. AHP method was used to assign the weights for various indexes of evaluation criteria ；TOPSIS method was used to retrospectively analyze and evaluate the rationality of 120 cases of type Ⅰ incision surgery from 3 orthopedic departments in Peking University People ’s Hospital during Sept. 1st-30th，2019. RESULTS ：Established evaluation system included 4 primary indicators （medication indication ，usage and dosage ，medication timing ，other factors ）and 12 secondary indicators. Among the secondary indicators ，indications，drug selection and timing of preoperative administration were the most important （weights were 0.209，0.140，0.117）. Among 120 cases，30.83％ of drug use were reasonable ，47.50％ were basically reasonable and 21.67％ were unreasonable. Evaluation results obtained by AHP-TOPSIS were consistent with the actual situation. CONCLUSIONS ：The rationality evaluation method of prophylactic use of antibiotics in type Ⅰ incision surgery based on AHP-TOPSIS method can quantitatively evaluate the rationality of drug use by combining multiple indicators. The method is feasible ，operable，and the evaluation results can be quantified ，which has a wide range of application.

Objective:To evaluate the efficacy and safety of preoperative intravitreal conbercept (IVC) as an adjunct to pars plana vitrectomy (PPV) in the treatment of proliferative diabetic retinopathy (PDR).Methods:A systematic search in EMbase, PubMed, Cochrane Library, Chinese periodical full text database (CNKI), Wanfang database and VIP database were conducted, studies about the effectiveness and safety of IVC combined with PPV in the management of PDR were collected.Two researchers independently screened the studies according to the inclusion criteria and exclusion criteria, and extracted the data.The quality of the randomized controlled trial (RCT) was evaluated by the modified Jadad scale, and the quality of the cohort study or case-control study was evaluated by the Newcastle Ottawa scale (NOS). Rev Man 5.3 was applied for data analysis.Results:A total of 11 RCTs, 2 cohort studies and 10 case-control studies involving 1 625 patients and 1 844 eyes were included.The final Jadad score for each RCT was more than 3, and the final NOS score for each cohort study and case-control study was more than 5.The results of Meta-analysis showed that the total effectiveness of treatment was significantly higher in the preoperative IVC group than that in the simple PPV group ( RR=1.31, 95% CI: 1.21-1.42, P<0.001). The average operation duration was significantly shorter in the preoperative IVC group compared with that in the simple PPV group (MD=-21.11, 95% CI: -26.39--15.83, P<0.001). The level of VEGF was significantly lower in the preoperative IVC group than that in the simple PPV group (MD=-15.33, 95% CI: -19.40--11.26, P<0.001). Preoperative IVC could reduce the incidences of intraoperative bleeding, iatrogenic retinal breaks, postoperative recurrent vitreous hemorrhage and temporary increase of intraocular pressure, with statistically significant differences between them (all at P<0.05). Conclusions:Preoperative intravitreal injection of conbercept shows better effect and safer than vitrectomy alone, and it has no serious side effect.
