Objective:To investigate the risk factors for aggravation of type 2 diabetic foot ulcer and the correlation between the level of infection and the severity of the disease,as well as the association of the detection rate of bacteria and the types of bacteria with disease severity in patients with type 2 diabetic foot ulcer,and to provide individualized guidance for the prevention,diagnosis,and treatment of type 2 diabetic foot.Methods:A retrospective analysis was performed for the data of 150 patients with type 2 diabetic foot who were treated in Department of Endocrinology,The First Affiliated Hospital of Kunming Medical University,from October 2021 to June 2023,and according to the Wagner grade of diabetic foot,these patients were divided into mild group A(35 patients with Wagner grade 2),moderate group B(58 patients with Wagner grade 3),and severe group C(57 patients with Wagner grade 4).The clinical data of the three groups were analyzed.Results:The severity of type 2 diabetic foot ulcer was correlated with white blood cell count,neutrophil count,platelet count,monocyte count,globulin,alkaline phosphatase,neutrophil-lymphocyte ratio,monocyte-lymphocyte ratio,platelet-lymphocyte ratio,high-sensitivity C-reactive protein,procalcitonin,interleukin-6,erythrocyte sedimentation rate,hemoglo-bin,albumin/globulin ratio,lymphocyte count,cholinesterase,albumin,fasting blood glucose,gamma-glutamyl transferase,glycated he-moglobin,blood uric acid,high-density lipoprotein cholesterol,total cholesterol,triglycerides,and low-density lipoprotein cholesterol(P<0.05).The multivariate ordinal logistic regression analysis showed that the neutrophil-lymphocyte ratio and erythrocyte sedi-mentation rate were independent risk factors for the progression of Wagner grade of diabetic foot(P<0.05).For groups A,B,and C,the detection rate of bacteria in foot ulcer secretion tended to increase with the severity of diabetic foot,with the highest detection rate in group C,followed by groups B and A.A total of 31 types of bacteria were detected in the three groups,and the proportion of Gram-positive bacteria was higher than that of Gram-negative bacteria,with Staphylococcus aureus accounting for the highest proportion of 27.72%in all samples.Conclusion:High-sensitivity C-reactive pro-tein,procalcitonin,interleukin-6,and erythrocyte sedimentation rate increase with the progression of the Wagner grade of diabetic foot,and neutrophil-lymphocyte ratio and erythrocyte sedimentation rate are independent risk factors for the progression of the Wagner grade of diabetic foot.The detection rate of bacteria in foot ulcer secretion tends to increase with the Wagner grade of diabetic foot,and Gram-positive bacteria account for a higher proportion than Gram-negative bacteria,with Staphylococcus aureus accounting for the highest proportion.

Objective To investigate correlations of peripheral blood inflammatory and immune-related indices with clinicopathological features and prognosis in breast cancer patients.Methods A total of 144 breast cancer patients admitted to the Breast Surgery Department of Maternity and Child Healthcare Hospital of Tongzhou District of Beijing were included in cancer group,44 patients with a-typical breast hyperplasia were included in precancerous lesion group,and 131 patients with breast hyperplasia were included in breast hyperplasia group.The neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),and lymphocyte-to-monocyte ratio(LMR)were compared among the three groups.A three-year follow-up was conducted for prognosis assessment.Based on different NLR,PLR,and LMR levels,the cancer group was divided into low NLR group(＜2.12,67 pa-tients),high NLR group(≥2.12,77 patients),low PLR group(＜133.21,65 patients),high PLR group(≥ 133.21,79 patients),low LMR group(＜5.05,80 patients),and high LMR group(≥5.05,64 patients).The correlations of NLR,PLR,and LMR with clinicopathological features and prognosis in breast cancer patients were analyzed.Results NLR in the cancer group was higher than that in the precancerous lesion group and breast hyperplasia group,the PLR was higher than that in the breast hyperplasia group,and the LMR was lower than that in the breast hyperplasia group(P＜0.05).NLR and PLR in the precancerous lesion group were higher and LMR was lower than those in the breast hyperplasia group(P＜0.05).PLR between patients with different menopa-usal statuses and Ki-67 levels showed statistically significant differences(P＜0.05).LMR between patients with different menopausal status also showed a statistically significant difference(P＜0.05).After a three-year follow-up,5 patients in the cancer group had a poor prognosis and 139 had a good prognosis.Poor prognosis rates between the low NLR and high NLR groups,low PLR and high PLR groups,and low LMR and high LMR groups showed statistically significant differences(P＜0.05).Logistic regression analysis results indicated that increased NLR and PLR were risk factors for poor prognosis in cancer patients,while increased LMR was a protective factor.Conclu-sion Peripheral blood inflammatory and immune-related indicators in breast cancer patients exhibit abnormal changes.Increased NLR and PLR are risk factors for poor prognosis,while increased LMR is a protective factor.

Bone formation and deposition are initiated by sensory nerve infiltration in adaptive bone remodeling. Here, we focused on the role of Semaphorin 3A (Sema3A), expressed by sensory nerves, in mechanical loads-induced bone formation and nerve withdrawal using orthodontic tooth movement (OTM) model. Firstly, bone formation was activated after the 3rd day of OTM, coinciding with a decrease in sensory nerves and an increase in pain threshold. Sema3A, rather than nerve growth factor (NGF), highly expressed in both trigeminal ganglion and the axons of periodontal ligament following the 3rd day of OTM. Moreover, in vitro mechanical loads upregulated Sema3A in neurons instead of in human periodontal ligament cells (hPDLCs) within 24 hours. Furthermore, exogenous Sema3A restored the suppressed alveolar bone formation and the osteogenic differentiation of hPDLCs induced by mechanical overload. Mechanistically, Sema3A prevented overstretching of F-actin induced by mechanical overload through ROCK2 pathway, maintaining mitochondrial dynamics as mitochondrial fusion. Therefore, Sema3A exhibits dual therapeutic effects in mechanical loads-induced bone formation, both as a pain-sensitive analgesic and a positive regulator for bone formation.

Idiopathic pulmonary fibrosis (IPF) is a chronic debilitating lung disease with unknown etiology, complex syndromes and prolonged illness, which is difficult to cure. Based on the theory of "spleen is the envoy" in Huang Di Nei Jing, this article explained the TCM meaning of "spleen is the envoy" and the relationship between spleen and other four organs, especially the relationship between spleen and lung. It is believed that the onset of IPF is due to deficiency of lung and spleen qi, loss of solid defense and evil invasion of the nutritive and defensive levels; qi deficiency and depression lead to heat damage to yin, while long-term blood damage to collaterals involves yang. The pathological process shows the changes from qi entering blood and from meridian to collateral, which eventually leads to the imbalance of qi and blood, yin and yang, the stagnation of phlegm and blood stasis, the obstruction of lung collateral, the mixture of excess and deficiency, and the lingering is difficult to heal. In the treatment, the "spleen is the envoy" is the center, the lung and spleen are treated together, the qi of lung and spleen is strengthened, the yin of lung and stomach is nourished, and finally the root is protected. The treatment is based on syndrome differentiation, modified with syndromes, and the methods of promoting blood circulation, resolving phlegm, warming yang and dredging collaterals are supplemented in time, which provides a new idea for enriching the differentiation and treatment of IPF in TCM.

OBJECTIVE: To carry out prenatal diagnosis and genetic analysis for a fetus with disorders of sex development (DSDs). METHODS: A fetus with DSDs who was identified at the Shenzhen People's Hospital in September 2021 was selected as the study subject. Combined molecular genetic techniques including quantitative fluorescence PCR (QF-PCR), multiplex ligation-dependent probe amplification (MLPA), chromosomal microarray analysis (CMA), quantitative real-time PCR (qPCR), as well as cytogenetic techniques such as karyotyping analysis and fluorescence in situ hybridization (FISH) were applied. Ultrasonography was used to observe the phenotype of sex development. RESULTS: Molecular genetic testing suggested that the fetus had mosaicism of Yq11.222qter deletion and X monosomy. Combined with the result of cytogenetic testing, its karyotype was determined as mos 45,X[34]/46,X,del(Y)(q11.222)[61]/47,X,del(Y)(q11.222),del(Y)(q11.222)[5]. Ultrasound examination suggested hypospadia, which was confirmed after elective abortion. Combined the results of genetic testing and phenotypic analysis, the fetus was ultimately diagnosed with DSDs. CONCLUSION This study has applied a variety of genetic techniques and ultrasonography to diagnose a fetus with DSDs with a complex karyotype.

BACKGROUND: Immunotherapy (IT) is recommended for the treatment of advanced non-small cell lung cancer (NSCLC), while brain radiotherapy (RT) is the mainstream treatment for patients with brain metastases (BM). This study aimed to investigate the efficacy and safety of combined use of RT and IT. METHODS: The date was limited to May 1, 2022, and literature searches were carried out in CNKI, Wanfang, PubMed, EMBASE and Cochrane databases. Heterogeneity was judged using the I2 test and P value. Publication bias was assessed using a funnel plot. The quality of included studies was assessed using the Newcastle-Ottawa Scale (NOS). Statistical analysis was performed using Stata 16.0 software. RESULTS: A total of 17 articles involving 2,636 patients were included. In the comparison of RT+IT group and RT group, no significant difference was found in overall survival (OS) (HR=0.85, 95%CI: 0.52-1.38, I2=73.9%, Pheterogeneity=0.001) and intracranial distance control (DBC) (HR=1.04, 95%CI: 0.55-1.05, I2=80.5%, Pheterogeneity<0.001), but the intracranial control (LC) in the RT+IT group was better than the RT group (HR=0.46, 95%CI: 0.22-0.94, I2=22.2%, Pheterogeneity=0.276), and the risk of radiation necrosis/treatment-related imaging changes (RN/TRIC) was higher than RT (HR=1.72, 95%CI: 1.12-2.65, I2=40.2%, Pheterogeneity=0.153). In the comparison between the RT+IT concurrent group and the sequential group, no significant difference was found in OS (HR=0.62, 95%CI: 0.27-1.43, I2=74.7%, Pheterogeneity=0.003) and RN/TRIC (HR=1.72, 95%CI: 0.85-3.47, I2=0%, Pheterogeneity=0.388) was different between the two groups. However, DBC in the concurrent treatment group was better than that in the sequential treatment group (HR=0.77, 95%CI: 0.62-0.96, I2=80.5%, Pheterogeneity<0.001). CONCLUSIONS RT combined with IT does not improve the OS of NSCLC patients with BM, but also increases the risk of RN/TRIC. In addition, compared with sequential RT and IT, concurrent RT and IT improved the efficacy of DBC.
