Gastric cancer is a common malignant tumor of the digestive tract and can be classified as “fullness of the stomach”， “epigastric pain”， “noise” and other categories in the field of traditional Chinese medicine. Sijunzi decoction is composed of Panax ginseng， Poria cocos， Atractylodes macrocephala， and honey-fried Glycyrrhiza uralensis， and it has the effect of tonifying qi and strengthening the spleen. This article summarizes the active ingredients， mechanism of action， and clinical application research progress of Sijunzi decoction in treating gastric cancer. The results show that the main active ingredients of Sijunzi decoction include ginsenosides， atractylenolide， pachymic acid， glycyrrhizic acid， etc.； Sijunzi decoction and its effective ingredients can play an anti-gastric cancer role by inhibiting the proliferation of gastric cancer cell， inducing apoptosis of gastric cancer cell， enhancing gastric cancer cell chemotherapy sensitivity， and inhibiting invasion and metastasis of gastric cancer cell. In addition， Sijunzi decoction can enhance the efficacy of chemotherapy drugs， strengthen the immune function of the body and lower serum cancer marker levels during the clinical treatment of gastric cancer.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Objective:To investigate the value of transanal multipoint full-layer puncture biopsy (TMFP) in predicting pathological complete response (pCR) after neoadjuvant radiotherapy and chemotherapy (nCRT) in patients with locally advanced rectal cancer (LARC) and to establish a predictive model for providing clinical guidance regarding the treatment of LARC.Methods:In this multicenter, prospective, cohort study, we collected data on 110 LARC patients from four hospitals between April 2020 and March 2023: Beijing Chaoyang Hospital of Capital Medical University (50 patients), Beijing Friendship Hospital of Capital Medical University (41 patients), Qilu Hospital of Shandong University (16 patients), and Zhongnan Hospital of Wuhan University (three patients). The patients had all received TMFP after completing standard nCRT. The variables studied included (1) clinicopathological characteristics; (2) clinical complete remission (cCR) and efficacy of TMFP in determining pCR after NCRT in LARC patients; and (3) hospital attended, sex, age, clinical T- and N-stages, distance between the lower margin of the tumor and the anal verge, baseline and post-radiotherapy serum carcinoembryonic antigen (CEA) and carbohydrate antigen (CA)19-9 concentrations, chemotherapy regimen, use of immunosuppressants with or without radiotherapy, radiation therapy dosage, interval between surgery and radiotherapy, surgical procedure, clinical T/N stage after radiotherapy, cCR, pathological results of TMFP, puncture method (endoscopic or percutaneous), and number and timing of punctures. Single-factor and multifactorial logistic regression analysis were used to determine the factors affecting pCR after NCRT in LARC patients. A prediction model was constructed based on the results of multivariat analysis and the performance of this model evaluated by analyzing subject work characteristics (ROC), calibration, and clinical decision-making (DCA) curves. pCR was defined as complete absence of tumor cells on microscopic examination of the surgical specimens of rectal cancer (including lymph node dissection) after NCRT, that is, ypT0+N0. cCR was defined according to the Chinese Neoadjuvant Rectal Cancer Waiting Watch Database Study Collaborative Group criteria after treatment, which specify an absence of ulceration and nodules on endoscopy; negative rectal palpation; no tumor signals on rectal MRI T2 and DWI sequences; normal serum CEA concentrations, and no evidence of recurrence on pelvic computed tomography/magnetic resonance imaging.Results:Of the 110 patients, 45 (40.9%) achieved pCR after nCRT, which was combined with immune checkpoint inhibitors in 34 (30.9%). cCR was diagnosed before puncture in 38 (34.5%) patients, 43 (39.1%) of the punctures being endoscopic. There were no complications of puncture such as enterocutaneous fistulae, vaginal injury, prostatic injury, or presacral bleeding . Only one (2.3%) patient had a small amount of blood in the stools, which was relieved by anal pressure. cCR had a sensitivity of 57.8% (26/45) for determining pCR, specificity of 81.5% (53/65), accuracy of 71.8% (79/110), positive predictive value 68.4% (26/38), and negative predictive value of 73.6% (53/72). In contrast, the sensitivity of TMFP pathology in determining pCR was 100% (45/45), specificity 66.2% (43/65), accuracy 80.0% (88/110), positive predictive value 67.2% (45/67), and negative predictive value 100.0% (43/43). In this study, the sensitivity of TMFP for pCR (100.0% vs. 57.8%, χ 2=24.09, P<0.001) was significantly higher than that for cCR. However, the accuracy of pCR did not differ significantly (80.0% vs. 71.8%, χ 2=2.01, P=0.156). Univariate and multivariate logistic regression analyses showed that a ≥4 cm distance between the lower edge of the tumor and the anal verge (OR=7.84, 95%CI: 1.48-41.45, P=0.015), non-cCR (OR=4.81, 95%CI: 1.39-16.69, P=0.013), and pathological diagnosis by TMFP (OR=114.29, the 95%CI: 11.07-1180.28, P<0.001) were risk factors for pCR after NCRT in LARC patients. Additionally, endoscopic puncture (OR=0.02, 95%CI: 0.05-0.77, P=0.020) was a protective factor for pCR after NCRT in LARC patients. The area under the ROC curve of the established prediction model was 0.934 (95%CI: 0.892-0.977), suggesting that the model has good discrimination. The calibration curve was relatively close to the ideal 45° reference line, indicating that the predicted values of the model were in good agreement with the actual values. A decision-making curve showed that the model had a good net clinical benefit. Conclusion:Our predictive model, which incorporates TMFP, has considerable accuracy in predicting pCR after nCRT in patients with locally advanced rectal cancer. This may provide a basis for more precisely selecting individualized therapy.

Objective·To investigate the current situation and distribution characteristics of chronic comorbidities,and to provide reference for further improving the self-management of comorbidities and implementing the whole course and all-round management of comorbidity.Methods·Two thousand and forty-five inpatients in the Department of Geriatrics,Renji Hospital,Shanghai Jiao Tong University School of Medicine were enrolled in this study from December 2020 to February 2023.The general vital signs,routine laboratory examination and disease status were collected.The epidemiological distribution characteristics of chronic diseases and comorbidities were analyzed.Results·The incidence of chronic diseases in the surveyed population was 99.6％,and the incidence of comorbidities was 94.2％.The top 5 chronic diseases were hypertension(43.68％),diabetes mellitus(24.81％),malignant tumor(21.48％),hyperlipidemia(18.38％)and coronary heart disease(11.99％).The detection rates of hypertension,diabetes mellitus,coronary heart disease,chronic obstructive pulmonary disease,stoke and chronic kidney disease in males were significantly higher than those in females(P＜0.05).The proportion of patients with 5 chronic diseases was the highest(11.99％),followed by 7 chronic diseases(10.26％)and 6 chronic diseases(10.04％).Among the patients of different ages,the comorbidity rate was the highest in the patients aged 50-59 years(27.78％).In different age groups,patients aged 50 to 59 with 2 chronic diseases had the highest incidence of comorbidity,which was as high as 40.82％.Although the overall proportion of comorbidities among male patients(95.37％)was higher than that among females(93.77％),there was no statistically significant difference(P=0.125).However,the proportions of male patients with 2 and 5 chronic diseases were 70.41％and 60.63％,respectively,which were significantly higher than those of female patients(29.59％and 39.37％).The correlations between coronary heart disease and diabetes mellitus,hypertension and coronary heart disease,hypertension and diabetes mellitus were higher(r=0.24,r=0.27,r=0.35,all P＜0.05).Conclusion·The prevalence of chronic diseases and comorbidities is high in the middle-aged and elderly population,and the number of comorbidities increases significantly with the increase of age.

Objective To evaluate the apparent diffusion coefficient(ADC)values of different bone marrow infiltration patterns in multiple myeloma(MM)patients with MR whole-body diffusion weighted imaging(WB-DWI)and to determine the ADC thresholds for different bone marrow infiltration patterns.Methods Nineteen MM patients diagnosed for the first time were selected.The lesions types of each site(cervical spine,ribs,sternum,humerus,scapula,sacral spine,ilium,femur,thoracic spine,and lumbar spine)after the WB-DWI images were visually evaluated,which were divided into focal group(including focal lesion in combined focal and diffuse infiltration)[region of interest(ROI)=141],pure diffuse infiltration group(ROI=150),diffuse lesion in combined focal and diffuse infiltration group(ROI=127),"salt-and-pepper"group(ROI=54),and normal appearance group(ROI=68).ADC values were measured and compared between each group and the receiver operating characteristic(ROC)curve was drawn to distinguish different patterns of bone marrow infiltration.Results There was no statistically significant difference in ADC values between the diffuse lesion in combined focal and diffuse infiltration group and the"salt-and-pepper"group(P＞0.99),and there was statistically significant difference in ADC values between the other groups(P＜0.05).The ROC curve showed that the area under the curve(AUC)for identifying focal group and the"salt-and-pepper"group was 0.889[95％confidence interval(CI)0.844-0.934],the AUC for identifying pure diffuse infiltration group and the normal appearance group was 0.968(95％CI 0.949-0.987).ADC values were able to accurately and visually differentiate between the different patterns of bone marrow infiltration.Conclusion The ADC values can be used as a quantitative tool to objectively distinguish different bone marrow infiltration patterns in MM patients.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objectives:to analyze the efficacy of percutaneous coronary intervention(PCI)for complex left main(LM)lesions combined with chronic total occlusion(CTO)of the right coronary artery. Methods:Ninety patients with complex left main lesions hospitalized in Hunan Provincial People's Hospital from January 2019 to December 2022 were consecutively included.According to the coronary angiographic vascular lesions,patients were divided into complex left main lesions combined with right coronary artery CTO(observation group,n=30)and complex left main lesions without right coronary artery CTO(control group,n=60).The baseline clinical data,intraoperative conditions,angiographic results,and postoperative follow-up results of the patients were analyzed and compared between the two groups. Results:Fifty-eight(64.4%)out of the 90 patients were male.There was no statistically significant difference between the two groups in terms of baseline clinical data(all P>0.05),left main lesion condition(P=1.000),left main calcification condition(P=0.249),and preoperative TIMI flow grading(P=1.000).In the comparison between observation group and the control group,intraoperative occurrence of no-reflow(3.3%vs.5.0%,P=1.000),hypotension(10.0%vs.8.3%,P=1.000),pericardial effusion(3.3%vs.0%,P=0.333),the percentage of intravascular ultrasound(IVUS)use(86.7%vs.90.0%,P=0.635),and the use of circulatory assist device(P=0.699),and the proportion of intraoperative coronary spinning(26.7%vs.21.7%,P=0.597)were all similar between the two groups.The median follow-up time was 14.50(11.83,15.85)months,and the differences in the incidence of major adverse cardiovascular events(MACE)such as recurrent angina,acute myocardial infarction,rebleeding,readmission for heart failure,and cardiac death(31.0%vs.32.1%,P=1.000)were not statistically significant between the observation group and the control group. Conclusions:PCI revascularization may be a viable approach for elderly patients with complex LM lesions with multiple underlying disease,and combined right coronary artery CTO,intolerance and reluctance to CABG.
