BACKGROUND Acute cholecystitis(AC)is a common disease in general surgery.Laparoscopic cholecystectomy(LC)is widely recognized as the"gold standard"surgical procedure for treating AC.For low-risk patients without complications,LC is the recommended treatment plan,but there is still controversy regarding the treatment strategy for moderate AC patients,which relies more on the surgeon's experience and the medical platform of the visiting unit.Percutaneous transhepatic gallbladder puncture drainage(PTGBD)can effectively alleviate gallbladder inflammation,reduce gallbladder wall edema and adhesion around the gallbladder,and create a"time window"for elective surgery.AIM To compare the clinical efficacy and safety of LC or PTGBD combined with LC for treating AC patients,providing a theoretical basis for choosing reasonable surgical methods for AC patients.METHODS In this study,we conducted a clinical investigation regarding the combined use of PTGBD tubes for the treatment of gastric cancer patients with AC.We performed searches in the following databases:PubMed,Web of Science,EMBASE,Cochrane Library,China National Knowledge Infrastructure,and Wanfang Database.The search encompassed literature published from the inception of these databases to the present.Subsequently,relevant data were extracted,and a meta-analysis was conducted using RevMan 5.3 software.RESULTS A comprehensive analysis was conducted,encompassing 24 studies involving a total of 2564 patients.These patients were categorized into two groups:1371 in the LC group and 1193 in the PTGBD+LC group.The outcomes of the meta-analysis revealed noteworthy disparities between the PTGBD+LC group and the LC group in multiple dimensions:(1)Operative time:Mean difference(MD)=17.51,95%CI:9.53-25.49,P<0.01;(2)Conversion to open surgery rate:Odds ratio(OR)=2.95,95%CI:1.90-4.58,P<0.01;(3)Intraoperative bleeding loss:MD=32.27,95%CI:23.03-41.50,P<0.01;(4)Postoperative hospital stay:MD=1.44,95%CI:0.14-2.73,P=0.03;(5)Overall postoperative compli-cation rate:OR=1.88,95%CI:1.45-2

Chinese Journal of Integrative Medicine 2024年第7期30卷 623-632页

作者： YUE Yin-zi LI Ming-xuan WANG xiao-hui QIN yuan-yuan WANG Ya-hui TAN Jin-hua SU Lian-lin YAN Shuai Department of General Surgery Suzhou TCM Hospital Affiliated to Nanjing University of Chinese Medicine School of Pharmacy Nanjing University of Chinese Medicine Department of General Surgery Bayinguoleng Mongolian Autonomous Prefecture People's Hospital Department of Pharmacy Suzhou TCM Hospital Affiliated to Nanjing University of Chinese Medicine Department of Anorectal Surgery Suzhou TCM Hospital Affiliated to Nanjing University of Chinese Medicine

Objective: To clarify the potential mechanism of Banxia Xiexin Decoction(BXD) on colorectal cancer(CRC) from the perspective of metabolomics. Methods: Forty male C57BL/6 mice were randomly divided into normal control(NC), azoxymethane/dextran sulfate sodium(AOM/DSS) model, low-dose BXD(L-BXD), high-dose BXD(H-BXD) and mesalamine(MS) groups according to a random number table, 8 mice in each group. Colorectal cancer model was induced by AOM/DSS. BXD was administered daily at doses of 3.915(L-BXD) and 15.66 g/kg(H-BXD) by gavage for consecutive 21 days, and 100 mg/kg MS was used as positive control. Following the entire modeling cycle, colon length of mice was measured and quantity of colorectal tumors were counted. The spleen and thymus index were determined by calculating the spleen/thymus weight to body weight. Inflammatory cytokine and changes of serum metabolites were analyzed by enzyme-linked immunosorbent assay kits and ultra performance liquid chromatography-quadrupole/time-of-flight mass spectrometry(UPLC-Q/TOF-MS), respectively. Results: Notably, BXD supplementation protected against weight loss, mitigated tumor formation, and diminished histologic damage in mice treated with AOM/DSS(P<0.05 or P<0.01). Moreover, BXD suppressed expression of serum inflammatory enzymes, and improved the spleen and thymus index(P<0.05). Compared with the normal group, 102 kinds of differential metabolites were screened in the AOM/DSS group, including 48 potential biomarkers, involving 18 main metabolic pathways. Totally 18 potential biomarkers related to CRC were identified, and the anti-CRC mechanism of BXD was closely related to D-glutamine and D-glutamate metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, arginine biosynthesis, nitrogen metabolism and so on. Conclusion: BXD exerts partial protective effects on AOM/DSS-induced CRC by reducing inflammation, protecting organism immunity ability, and regulating amino acid metabolism.

Diabetic eye disease refers to a group of eye complications that occur in diabetic patients and include diabetic retinopathy, diabetic macular edema, diabetic cataracts, and diabetic glaucoma. However, the global epidemiology of these conditions has not been well characterized. In this study, we collected information on diabetic eye disease-related research grants from seven representative countries––the United States, China, Japan, the United Kingdom, Spain, Germany, and France––by searching for all global diabetic eye disease journal articles in the Web of Science and Pub Med databases, all global registered clinical trials in the Clinical Trials database, and new drugs approved by the United States, China, Japan, and EU agencies from 2012 to 2021. During this time period, diabetic retinopathy accounted for the vast majority(89.53%) of the 2288 government research grants that were funded to investigate diabetic eye disease, followed by diabetic macular edema(9.27%). The United States granted the most research funding for diabetic eye disease out of the seven countries assessed. The research objectives of grants focusing on diabetic retinopathy and diabetic macular edema differed by country. Additionally, the United States was dominant in terms of research output, publishing 17.53% of global papers about diabetic eye disease and receiving 22.58% of total citations. The United States and the United Kingdom led international collaborations in research into diabetic eye disease. Of the 415 clinical trials that we identified, diabetic macular edema was the major disease that was targeted for drug development(58.19%). Approximately half of the trials(49.13%) pertained to angiogenesis. However, few drugs were approved for ophthalmic(40 out of 1830;2.19%) and diabetic eye disease(3 out of 1830;0.02%) applications. Our findings show that basic and translational research related to diabetic eye disease in the past decade has not been highly active, and has yielded few new treatment methods and newly approved drugs.

China Foundry 2024年第3期21卷 205-212页

作者： Guan-yu Jiang Meng-wu Wu xiao-guang Yang hui Wang Yu-yuan Zhu Hubei Key Laboratory of Advanced Technology for Automotive Components Wuhan University of TechnologyWuhan 430070China Hubei Longzhong Laboratory Xiangyang 441000HubeiChina Wescast Industries(China)Co. Ltd.Wuhan 430100China

Three types of steels were designed on the basis of GX40CrNiSi25-12 austenitic heat resistant steel by adding different Mn contents(2wt.%,6wt.%,and 12wt.%).Thermodynamic calculation,microstructure characterization and mechanical property tests were conducted to investigate the effect of Mn addition on the microstructure and mechanical properties of the austenitic heat resistant steel.Results show that the matrix structure in all the three types of steels at room temperature is completely austenite.Carbides NbC and M_(23)C_(6)precipitate at grain boundaries of austenite matrix.With the increase of Mn content,the number of carbides increases and their distribution becomes more uniform.With the Mn content increases from 1.99%to 12.06%,the ultimate tensile strength,yield strength and elongation increase by 14.6%,8.0%and 46.3%,respectively.The improvement of the mechanical properties of austenitic steels can be explained by utilizing classic theories of alloy strengthening,including solid solution strengthening,precipitation strengthening,and grain refinement.The increase in alloy strength can be attributed to solid solution strengthening and precipitation strengthening caused by the addition of Mn.The improvement of the plasticity of austenitic steels can be explained from two aspects:grain refinement and homogenization of precipitated phases.

Objective Postoperative delirium(POD)has become a critical challenge with severe consequences and increased incidences as the global population ages.However,the underlying mechanism is yet unknown.Our study aimed to explore the changes in metabolites in three specific brain regions and saliva of older mice with postoperative delirium behavior and to identify potential non-invasive biomarkers.Methods Eighteen-month-old male C57/BL6 mice were randomly assigned to the anesthesia/surgery or control group.Behavioral tests were conducted 24 h before surgery and 6,9,and 24 h after surgery.Complement C3(C3)and S100 calcium-binding protein B protein(S100beta)levels were measured in the hippocampus,and a metabolomics analysis was performed on saliva,hippocampus,cortex,and amygdala samples.Results In total,43,33,38,and 14 differential metabolites were detected in the saliva,hippocampus,cortex,and amygdala,respectively.“Pyruvate”“alpha-linolenic acid”and“2-oleoyl-1-palmitoy-snglycero-3-phosphocholine”are enriched in one common pathway and may be potential non-invasive biomarkers for POD.Common changes were observed in the three brain regions,with the upregulation of 1-methylhistidine and downregulation of D-glutamine.Conclusion Dysfunctions in energy metabolism,oxidative stress,and neurotransmitter dysregulation are implicated in the development of POD.The identification of changes in the level of salivary metabolite biomarkers could aid in the development of noninvasive diagnostic methods for POD.
