ObjectiveTo evaluate the clinical efficacy and safety of the traditional Chinese medicine （TCM） compound Chaiqin Xiaoyong Decoction （柴芩消痈饮， CXD） combined with Jinhuang Ointment （金黄膏， JO） in treating the nodular stage of acne mastitis of liver meridian heat accumulation type. MethodsA randomized， double-blind， placebo-controlled clinical trial was conducted. A total of 108 patients with liver meridian heat accumulation type acne mastitis in the nodular stage were randomly assigned to a treatment group and a control group， with 54 patients in each group. Both groups received topical application of JO once daily at a thickness of 3~5 mm for 8 hours， along with standard nursing care. On this basis， the treatment group received oral CXD granules， while the control group received placebo granules， administered twice daily， 3 sachets per dose， for 14 consecutive days. Clinical efficacy， TCM symptom scores， nodule size， visual analogue scale （VAS） pain scores， white blood cell （WBC） count， C-reactive protein （CRP） level， and systemic immune-inflammation index （SII） were compared. At the end of treatment， efficacy and safety indicators were evaluated. A 6-month follow-up was conducted to compare the proportion of patients undergoing surgical treatment. ResultsThe total clinical efficacy rate in the treatment group was 90.38% （47/52）， significantly higher than 32.00% （16/50） in the control group （P＜0.01）. The treatment group also showed significantly lower TCM symptom scores， VAS scores， nodule size， WBC count， CRP level， and SII （P＜0.05 or P＜0.01）. During follow-up， the surgical intervention rate in the treatment group was 5.77% （3/52）， lower than 14.00% （7/50） in the control group， with a statistically significant difference （P＜0.01）. No significant abnormalities were observed in safety indicators before and after treatment in either group. ConclusionCXD effectively reduces nodule size and alleviates symptoms such as redness and pain in patients with acne mastitis of liver meridian heat accumulation type， improves TCM symptom scores， enhances overall clinical efficacy， and demonstrates good safety.

Esophageal cancer is one of the malignant tumors that poses a threat to human health, with both high incidence and malignancy. Currently, surgery following neoadjuvant chemoradiotherapy is the standard treatment for locally advanced esophageal cancer; however, the long-term prognosis remains unsatisfactory. In recent years, inhibitors of programmed death protein-1 (PD-1) and its ligand (programmed death ligand-1, PD-L1) have achieved breakthrough progress in other solid tumors, and research on esophageal cancer is gradually being conducted. With the demonstration of good efficacy of PD-1/PD-L1 inhibitors in the first-line and second-line treatment of advanced unresectable esophageal cancer, their incorporation into neoadjuvant treatment regimens has become a hot topic. Therefore, this article reviews the mechanism of action of PD-1/PD-L1 inhibitors and their application in the neoadjuvant treatment of esophageal cancer.

BACKGROUND: The STAR (Scientific, Transparent, and Applicable Rankings) working group conducts regular evaluations of Chinese guidelines and consensus statements. This study gathered insights from STAR working group members using qualitative interviews. METHODS: From March to August 2023, members of the STAR specialist committees were interviewed using semi-structured interview outline. The interviewees were selected through purpose-based sampling. Subject analysis was employed to summarize the findings. RESULTS: We conducted interviews with 37 members from 36 committees and summarized the contents into four main themes and 16 specific topics. The value of STAR in enhancing the development and selection of high-quality guidelines in China was commonly mentioned. Challenges identified included the lack of resources and suboptimal organizational structures, collaboration, and evaluation efficiency. Suggestions for the STAR tool included developing extensions for different guideline types, adjusting certain items, and better covering guideline applicability. The promotion of STAR and the consideration of an international committee for global outreach were also highlighted. CONCLUSION STAR has exerted a substantial influence on the evaluation of Chinese guidelines, and the insights gained from interviews offer valuable directions for its further enhancement.

Objective:To investigate the predictive value of controlling nutritional status (CONUT) score in the prognosis of patients with advanced diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 654 patients newly diagnosed with advanced DLBCL diagnosed in 7 medical centers in Huaihai Lymphoma Working Group from October 2009 to January 2022 were retrospectively collected. All the patients received rituximab-based immune chemotherapy regimens. The patients were randomly assigned to the training set (458 cases) and the validation set (196 cases) in a 7:3 ratio. The clinicopathological data of patients were collected, and the CONUT score was calculated based on albumin, lymphocyte count, and total cholesterol. The optimal critical value of CONUT scote was determined by using MaxStat method. Kaplan-Meier method was used to draw survival curves; Cox proportional hazards model was used to make univariate analysis and multivariate analysis on the factors influencing overall survival (OS). The efficacy of CONUT score in combination with the International prognostic index (IPI) and an enhanced IPI (NCCN-IPI) in predicting OS was evaluated by using receiver operating characteristic (ROC) curves.Results:The median follow-up time of 654 patients was 38.1 months (95% CI: 35.3 months- 40.9 months), and the 5-year OS rate was 49.2%. According to the MaxStat method, the optimal critical value for CONUT score was determined to be 6 points. All the patients were classified into the normal nutritional status group (CONUT score ≤ 6 points, 489 cases) and the poor nutritional status group (CONUT score > 6 points, 165 cases). The results of the multivariate analysis showed that CONUT score > 6 points, male, lactate dehydrogenase >240 U/L, high white blood cell count, low hemoglobin level and age > 60 years were independent risk factors for OS of patients with advanced DLBCL (all P < 0.05). Patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group in the overall cohort of advanced DLBCL. Subgroup analysis revealed that among patients with Eastern Cooperative Oncology Group-performance status (ECOG PS) score < 2 points, IPI low-intermediate risk, IPI intermediate-high risk, NCCN-IPI low-intermediate risk, and NCCN-IPI intermediate-high risk, the patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group (CONUT score ≤ 6 points) (all P < 0.05). Conclusions:CONUT score has a certain value in the assessment of the prognosis of patients with advanced DLBCL, and its predictive efficacy is further improved when combined with IPI and NCCN-IPI.

Surgery is the preferred treatment for resectable esophageal cancer, but in locally advanced esophageal cancer, the effect of surgery alone is not ideal, so surgery-based comprehensive treatment is the best option. Neoadjuvant therapy has become a standard treatment in the treatment of locally advanced resectable esophageal cancer. Neoadjuvant therapy includes neoadjuvant chemotherapy, radiochemotherapy, immunotherapy, targeted therapy, etc. With the significant efficacy and acceptable toxicity of immunotherapy in the first-line and second-line treatment of advanced esophageal cancer, neoadjuvant immunotherapy has become a research hotspot of locally advanced resectable esophageal cancer. This article reviews the latest research progress and some limitations of neoadjuvant immunotherapy in locally advanced resectable esophageal cancer.

Objective To analyze the influence of intraoperative blood glucose fluctuation and postoperative insulin resistance(IR)on postoperative cognitive dyfunction(POCD)in elderly patients undergoing thoracoscopic radical resection of lung cancer under general anesthesia.Methods A total of 352 elderly patients undergoing thoracoscopic radical resection of lung cancer under general anesthesia were collected and divided into the POCD group(n=84)and the non-POCD group(n=268).The covariates between the two groups were balanced by propensity score matching method(PSM).Eighty-four cases in each group were successfully matched.The data between the two groups before and after PSM were compared.After PSM,receiver operating characteristic(ROC)curve of blood glucose fluctuation amplitude for predicting POCD was drawn,and patients were divided into the low-level blood glucose fluctuation group(n=97)and the high-level blood glucose fluctuation group(n=71)according to the cut-off value.According to the existence of postoperative IR,patients were divided into the IR group(n=53)and the non-IR group(n=115).Then,incidences of POCD between groups were compared.Logistic regression was used to analyze the influencing factors of POCD.Results Before PSM,the POCD group had older age,higher blood glucose fluctuation amplitude,IR ratio,operation time,anesthesia time,propofol dosage,remifentanil dosage and sufentanil dosage in anesthesia maintenance period than those in the non-POCD group(P＜0.05).The POCD group had higher blood glucose fluctuation amplitude and IR ratio than those in the non-POCD group after PSM(P＜0.05).After PSM,the incidences of POCD in the high-level blood glucose fluctuation group and the IR group were higher than those in the low-level blood glucose fluctuation group and the non-IR group(P＜0.05).Logistic regression analysis showed that higher intraoperative blood glucose fluctuation(OR=9.140,95%CI:4.338-19.257)and postoperative IR(OR=4.034,95%CI:1.163-13.991)were risk factors of POCD.Conclusion The risk of POCD in elderly patients undergoing thoracoscopic radical lung cancer surgery under general anesthesia is increased in patients with higher intraoperative blood glucose fluctuation and postoperative IR.

Craniovertebral junction malformation is a congenital malformation located in the foramen magnum and upper cervical spine, including bone and nerve malformation, resulting in motor and sensory disorders, cerebellar and lower cranial nerves, etc. The evaluation methods of clinical symptoms and efficacy of craniovertebral junction malformation are important for the surgical indications and effects, mainly including the evaluation of clinical symptoms and the quality of life. At present, the commonly used methods in clinical work and literature are the Japanese orthopaedic association scores, visual analogue scales, 36-item short-form health survey, etc. Most of these clinical evaluations are not aimed at craniovertebral junction diseases but focus on the description of a certain type of clinical symptoms. Chicago Chiari outcome scale and syringomyelia outcome scale of Xuanwu hospital are dedicated to Craniovertebral junction malformation, but more clinical studies are needed to prove their effectiveness. Based on the literature reports, this article reviewed the previous clinical evaluation methods of craniovertebral junction malformation and discusses their applications and limitations.

Background:Following the short-term outbreak of coronavirus disease 2019(COVID-19)in December 2022 in China,clinical data on kidney transplant recipients(KTRs)with COVID-19 are lacking.Methods:We conducted a single-center retrospective study to describe the clinical features,complications,and mortality rates of hospitalized KTRs infected with COVID-19 between Dec.16,2022 and Jan.31,2023.The patients were followed up until Mar.31,2023.Results:A total of 324 KTRs with COVID-19 were included.The median age was 49 years.The median time between the onset of symptoms and admission was 13 d.Molnupiravir,azvudine,and nirmatrelvir/ritonavir were administered to 67(20.7%),11(3.4%),and 148(45.7%)patients,respectively.Twenty-nine(9.0%)patients were treated with more than one antiviral agent.Forty-eight(14.8%)patients were treated with tocilizumab and 53(16.4%)patients received baricitinib therapy.The acute kidney injury(AKI)occurred in 81(25.0%)patients and 39(12.0%)patients were admitted to intensive care units.Fungal infections were observed in 55(17.0%)patients.Fifty(15.4%)patients lost their graft.The 28-d mortality rate of patients was 9.0%and 42(13.0%)patients died by the end of follow-up.Multivariate Cox regression analysis identified that cerebrovascular disease,AKI incidence,interleukin(IL)-6 level of>6.8 pg/mL,daily dose of corticosteroids of>50 mg,and fungal infection were all associated with an increased risk of death for hospitalized patients.Conclusions:Our findings demonstrate that hospitalized KTRs with COVID-19 are at high risk of mortality.The administration of immunomodulators or the late application of antiviral drugs does not improve patient survival,while higher doses of corticosteroids may increase the death risk.

Objective:To investigate the application value of fecal Syndecan-2 (SDC2) gene methylated SDC2 (m SDC2) detection in colorectal cancer (CRC) screening among urban residents in Guangzhou City. Methods:A cross-sectional study was conducted in Shitan Town, Zengcheng District, Guangzhou City from July to December 2022. A community-based screening program for CRC was conducted among residents aged 40-74 years old. m SDC2 detection was employed in the participants, and those with positive results should be recommended to receive colonoscopy examination. The positive rate of m SDC2 detection, colonoscopy compliance rate, detection rate of intestinal lesions and clinicopathological characteristics were observed. The relationship between cycle threshold (CT) value of m SDC2 and intestinal lesions was explored. Further, the cost-effectiveness of screening was evaluated. Results:A total of 8 189 fecal samples were collected from 8 877 participants with the recovery rate of 92.25%. 8 048 qualified samples were enrolled in this study, consisted of 3 182 males (39.54%) and 4 866 females (60.46%), with the average age of 56 years old (40-74 years). The positive rate of m SDC2 detection was 7.99% (643/8 048), and the compliance rate of colonoscopy was 73.10% (470/643). 20 cases (4.25%) of colorectal cancer, 109 cases (23.19%) of advanced adenoma, 145 cases (30.85%) of non-advanced adenoma, 79 cases (16.81%) of polyps were detected. The detection rate of intestinal lesions was 75.11% and indicated significant differences in gender and age. 20 CRCs included 15 of stage 0-I, 4 of stage Ⅱ-Ⅲ and 1 of unknown stage. The CT value of m SDC2 was negatively correlated with the proportion of advanced colorectal neoplasms ( χ2=16.063, P<0.001). The total cost of the screening was 4.339 5 million yuan, the screening benefit was 28.506 2 million yuan, and the benefit-cost ratio was 6.57. Conclusion:The CRC screening strategy of fecal m SDC2 detection combined with colonoscopy has high colonoscopy compliance and detection rate of intestinal lesions, which is conducive to the detection of early CRCs, and has good cost-effectiveness. This study suggests that this method may be applied to the general CRC screening in China and contribute to the prevention of CRC. The CT value of m SDC2 may have a certain suggestion on the malignant degree of intestinal tumors.
