OBJECTIVES:
Papular dermatoses commonly affecting the female vulva, such as molluscum contagiosum, syringoma, lymphangioma, folliculitis, verruca vulgaris, ectopic sebaceous glands, and bowenoid papulosis, often present with similar clinical appearances and are frequently misdiagnosed. This study aims to explore the clinical diagnostic value of reflectance confocal microscopy (RCM) in differentiating these conditions.
METHODS:
A retrospective analysis was conducted on RCM imaging and histopathological findings from lesion sites in 172 female patients with vulval papular dermatoses. RCM characteristics confirmed by biopsy were summarized and diagnostic clues were explored.
RESULTS:
RCM diagnosis was consistent with histopathological diagnosis in 147 out of 172 cases (85.47%). Molluscum contagiosum, syringoma, lymphangioma, and folliculitis all exhibited cystic-like structures under RCM, differing in the location of the structures, wall characteristics, internal contents, and reflectivity. Verruca vulgaris, ectopic sebaceous glands, and bowenoid papulosis lacked such structures. Verruca vulgaris showed distinctive low-refractive vacuolated cells in the spinous layer; bowenoid papulosis exhibited mild cytologic atypia in the spinous layer; ectopic sebaceous glands were characterized by moderately to low-refractive, fish roe-like sebaceous lobules within the dermis.
CONCLUSIONS
RCM enables noninvasive, real-time, and dynamic visualization of key diagnostic and differential features of common vulvar papular dermatoses in women, offering high diagnostic value.

OBJECTIVE:
To construct and validate a prognostic prediction model for children with sepsis using the Phoenix sepsis score (PSS).
METHODS:
A retrospective case series study was conducted to collect clinical data of children with sepsis admitted to the pediatric intensive care unit (PICU) of the Affiliated Hospital of Guizhou Medical University from January 2022 to April 2024. The data included general information, the worst values of laboratory indicators within the first 24 hours of PICU admission, PSS score, pediatric critical illness score (PCIS), and the survival status of the children within 30 days of admission. The statistically significant indicators in univariate Logistic regression analysis were included in multivariate Logistic regression analysis to screen the risk factors affecting the prognosis of children with sepsis and construct a nomogram model. The receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive performance of the model. The Bootstrap method was used to perform 1 000 repeated sampling internal verification and draw the calibration curve of the model.
RESULTS:
A total of 199 children with sepsis were included, of which 32 died and 167 survived 30 days after admission. In the univariate Logistic regression analysis, shock, white blood cell count (WBC), international normalized ratio (INR), lactic acid (Lac), PSS score, and PCIS score were identified as statistically significant predictors. These variables were then included in the multivariate Logistic regression analysis, which demonstrated that shock [odds ratio (OR) = 4.258, 95% confidence interval (95%CI) was 1.049-17.288], WBC (OR = 1.124, 95%CI was 1.052-1.210), and PSS score (OR = 1.977, 95%CI was 1.298-3.012) were independent risk factors for mortality in pediatric patients with sepsis (all P < 0.05). A nomogram model was constructed based on these three risk factors, with the model equation as follows: -4.809+1.449×shock+0.682×PSS score+0.117×WBC. The calibration curve results showed that the model's predictions were highly consistent with the actual observations. The ROC curve showed that when the Youden index of the prediction model was 0.792, the sensitivity and specificity were 90.6% and 88.6%, respectively, and the area under the curve (AUC) was 0.957 (95%CI was 0.930-0.984), which was higher than the AUC of shock, WBC, and PSS score alone (0.808, 0.667, 0.908, respectively).
CONCLUSIONS
Shock, WBC, and PSS score have demonstrated certain predictive value for mortality in children with sepsis. The nomogram model based on the above indicators has important clinical significance for evaluating the prognosis and guiding treatment of children with sepsis.

Objective:To explore the efficacy of immune checkpoint inhibitors combined with adjuvant chemotherapy in patients with phase III gastric cancer and esophagogastric junction cancer.Methods:This study used a retrospective cohort study method based on real-world data. Clinical data of 403 patients with stage III gastric/esophagogastric junction cancer who underwent gastrectomy followed by adjuvant therapy in the Department of Gastric Surgery at Sun Yat-sen University Cancer Center from January 2020 to December 2023 were retrospectively collected. The study cohort comprised 147 (36.5%) patients with stage IIIA, 130 (32.3%) with stage IIIB, and 126 (31.3%) with stage IIIC gastric/esophagogastric junction cancer. Of them, 15 (3.7%) were HER-2 positive, 25 (6.2%) dMMR, and 22 (5.5%) patients Epstein-Barr virus encoding RNA (EBER) positive. Based on treatment plans, the patients were divided into immune checkpoint inhibitor combined with chemotherapy group (immune therapy group, n=110, 71 males and 39 females, median age 59 years old) and chemotherapy alone group (chemotherapy group, n=293, 186 males and 107 females, median age 60 years old). All patients in the immunotherapy group received immune checkpoint inhibitors targeting the programmed cell death protein-1 (PD-1) and its ligand (PD-L1). Of them, 85 received pembrolizumab, 10 received sintilimab, 8 received tislelizumab, 4 received camrelizumab, 2 received toripalimab, and 1 received pabocizumab. The adjuvant chemotherapy regimens used among the chemotherapy alone group includes SOX regimen (132 cases), XELOX (102 cases), S-1 monotherapy (44 cases), and other regimens (15 cases). The 3-year DFS rate of the two groups was compared, and subgroup analysis was conducted based on different ages, molecular phenotypes, pTNM staging, extranodal infiltration, and tumor length. Results:The median follow-up was 20.5 months (range 3.1~46.3), with a 3-year overall DFS rate of 61.4% for the entire 403 patients. The 3-year DFS rate for the immunotherapy group was 82.7%, higher than the chemotherapy alone group (58.8%), with a statistically significant difference ( P=0.021). Multivariate analysis showed that postoperative immunotherapy was a protective factor for DFS (HR=0.352, 95%CI: 0.180~0.685). Subgroup analysis showed that stage IIIC (HR=0.416, 95%CI: 0.184~0.940), aged ≥60 years (HR=0.336, 95%CI: 0.121~0.934) and extranodal invasion (HR=0.378, 95%CI: 0.170~0.839) were associated with benefit from the combined immune adjuvant chemotherapy, while no association was observed for MMR, HER-2 or EBER status. Conclusion:Stage III gastric/esophagogastric junction cancer patients may benefite from postoperative immune checkpoint inhibitor combined with adjuvant chemotherapy in real-world settings.

Objective To explore the feasibility and operability in identifying the therapeutic dominant stages of traditional Chinese medicine(TCM)based on subdivision model of disease course.Methods The hierarchical Bayesian model was used to differentiate the disease course of 125 cases of premature ovarian failure(POF),and the disease course of POF were divided into the occult stage,diminished ovarian reserve(DOR)stage,premature ovarian insufficiency(POI)stage,and POF stage.An then the paired sample t-test,Pearson correlation analysis and expert in-depth interview were used for the analysis of the therapeutic effects of TCM for POF at various stages.Results(1)Compared with POF stage,DOR and POI stages were frequently intervened by Chinese patent medicine.(2)In DOR(complicated with POI)stage and POF stage,there was significant difference between the degree of TCM intervention and the therapeutic effect(t =-3.70,P<0.001).(3)The degree of TCM intervention was positively correlated with treatment outcomes in the DOR stage(r = 0.679,P<0.001),so did in the POF stage(r = 0.432,P<0.001),but the correlation in the POF stage was slightly lower than that in the DOR stage.(4)The results of in-depth interviews with experts of TCM gynecology showed that in the concealed phase of POF,the prognosis would be most favorable if TCM regulation and intervention were performed.In the DOR stage and POI stage,treatment with Chinese medicine prescriptions usually brought about better curative effect and prognosis.For the patients at POF stage,the therapeutic effect of TCM depended on the patients'compliance and the treatment course,and the effect was relatively not as good as that of the previous stages.Conclusion In the DOR stage and POF stage,the higher the degree of TCM intervention,the better the prognosis will be achieved for the patients treated with western medicine.In the POF stage,the efficacy of TCM intervention is reduced to a certain extent compared with the DOR stage.The results indicated that it is feasible and operable to identify the TCM therapeutic dominant stages based on the subdivision model of disease course.

It has been well documented that exercise can improve bone metabolism, promote bone growth and development, and alleviate bone loss. MicroRNAs (miRNAs) are widely involved in the proliferation and differentiation of bone marrow mesenchymal stem cells, osteoblasts, osteoclasts and other bone tissue cells, and regulation of balance between bone formation and bone resorption by targeting osteogenic factors or bone resorption factors. Thus miRNAs play an important role in the regulation of bone metabolism. Recently, regulation of miRNAs are shown to be one of the ways by which exercise or mechanical stress promotes the positive balance of bone metabolism. Exercise induces changes of miRNAs expression in bone tissue and regulates the expression of related osteogenic factors or bone resorption factors, to further strengthen the osteogenic effect of exercise. This review summarizes relevant studies on the mechanism whereby exercise regulates bone metabolism via miRNAs, providing a theoretical basis for osteoporosis prevention and treatment with exercise.

Objective: To forecast mortality, age-standardized mortality, and probability of premature mortality from diabetes, and to simulate the impact of controlling risk factors by 2030 in China. Methods: We simulated the burden of disease from diabetes in six scenarios according to the development goals of risk factors control by the WHO and Chinese government. Based on the theory of comparative risk assessment and the estimates of the burden of disease for China from the Global Burden of Disease Study 2015, we used the proportional change model to project the number of deaths, age-standardized mortality, and probability of premature mortality from diabetes under different scenarios of risk factors control in 2030. Results: If the trends in exposures to risk factors from 1990 to 2015 continued. Mortality, age-standardized mortality, and probability of premature mortality from diabetes would increase to 32.57/100 000, 17.32/100 000, and 0.84% by 2030, respectively. During that time, mortality, age-standardized mortality and probability of premature mortality for males would all be higher than for females. If the goals of controlling risk factors were all achieved, the number of deaths from diabetes in 2030 would decrease by 62.10% compared to the predicted numbers based on the historical trends in exposure to risk factors, and the probability of premature mortality would drop to 0.29%. If only the exposure to a single risk factor were achieved by 2030, high fasting plasma glucose control would have the greatest impact on diabetes, resulting in a 56.00% reduction in deaths compared to the predicted numbers based on the historical trends, followed by high BMI (4.92%), smoking (0.65%), and low physical activity (0.53%). Conclusions: Risk factors control plays an important role in reducing the number of deaths, age-standardized mortality rate, and probability of premature mortality from diabetes. We suggest taking comprehensive measures to control relevant risk factors for certain populations and regions, to achieve the goal of reducing the burden of disease from diabetes as expected.
