Objective To explore the risk factors for obstetric septic shock.Methods The clinical data of 122 obstetric sepsis patients from Jan.2013 to Apr.2025 were retrospectively analyzed.The patients were assigned to shock group(n=26)or non-shock group(n=96)based on whether they progressed to septic shock.Variables including age,body mass index,multiple pregnancy,sequential organ failure assessment(SOFA)score,organ dysfunction status,white blood cell count(WBC),neutrophil count(NEU),neutrophil ratio,platelet count,procalcitonin,C-reactive protein,lactate(Lac),and D-dimer were recorded.Multivariate logistic regression analysis was used to identify the independent risk factors for obstetric septic shock.The predictive efficacy of these factors was evaluated using receiver operating characteristic(ROC)curve analysis.Results The proportions of patients aged≥35 years,and those with respiratory,cardiac,or central nervous system dysfunction,were significantly higher in the shock group than in the non-shock group,and the SOFA score,WBC,NEU,neutrophil ratio and Lac level were significantly higher in the shock group(all P＜0.05).Multivariate logistic regression analysis showed that increased NEU(odds ratio[OR]=1.093,95%confidence interval[CI]1.022-1.169,P=0.010)and age≥35 years(OR=3.433,95%CI 1.112-10.602,P=0.032)were independent risk factors for obstetric septic shock.ROC curve analysis showed that NEU had predictive value for obstetric septic shock(area under curve=0.741,95%CI 0.634-0.848),with an optimal cut-offvalue of 17.17×109/L.Conclusion Increased NEU and age≥35 years are independent risk factors for obstetric septic shock.NEU has predictive value for the development of obstetric septic shock and may serve as an important indicator for clinical assessment and timely treatment.

Objective To explore the hearing characteristics and early screening methods of hearing loss in diabetes mellitus(DM)patients.Methods From September 2022 to November 2023,800 DM patients in the Department of Endocrinology in People's Liberation Army General Hospital of Southern Theater Command were enrolled.According to the results of electrical audiometry,they were divided into a normal hearing DM group(n=214)and a hearing loss group(n=586).Binary logistic regression was used to analyze the influencing factors of hearing loss in DM patients.Results Age,homeostasis model assessment of insulin resistance(HOMA-IR),serum creatinine(Scr),urinary albumin/creatinine ratio(UACR)DM duration,hearing loss value,and proportion of DPN,DR,DKD,hypertension,coronary heart disease,perceived hearing loss,DPOAE abnormality and ABR abnormality in hearing loss group was higher than that in normal hearing group(P<0.05).DBP,homeostasis model insulin sensitivity index and estimated glomerular filtration rate(eGFR)were lower than those in normal hearing group(P<0.05).Logistic regression analysis showed that DM duration(OR 0.987,95%CI 0.987～1.002,P=0.001),eGFR(OR 0.974,95%CI 0.964～0.983,P=0.000),and hypertension(OR 0.659,95%CI 0.443～0.980,P=0.040)and coronary heart disease(OR 0.488,95%CI 0.246～0.968,P=0.040)were the influencing factors of hearing loss in DM patients.Conclusions Hearing loss is the complications of DM and is related to factors such as the DM duration.Given the insidious onset of hearing loss,DM patients should undergo a combined hearing screening using multiple methods in the early stage.

Objective:To explore the association between the use of tetracyclines during pregnancy and congenital malformations, with the aim of providing evidence-based guidance for the rational use of antibiotics during pregnancy.Methods:Data from the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) and the Canada Vigilance Adverse Reaction (CVAR) database from January 2015 to September 2024 were collected. Five methods including Tree-based scan statistic (TreeScan), proportional reporting ratio (PRR), reporting odds ratio (ROR), the UK Medicines and Healthcare Products Regulatory Agency (MHRA) comprehensive standard, and the Bayesian confidence propagation neural network (BCPNN) were used to detect signals of risk for congenital malformations in offspring following maternal use of tetracyclines during pregnancy. A signal that met the threshold criteria of all above 5 methods was considered as a risk signal. Based on population-based cohort of the drug exposures and adverse pregnancy outcomes (DEEP) data from January 2013 to December 2021 in Xiamen City, propensity score matching (PSM)-based Poisson regression was applied to evaluate the association between the first-trimester tetracyclines exposure and congenital malformations in offspring. Adjusted relative risk (a RR) and its 95% confidence interval ( CI) were calculated. Sensitivity analysis was conducted to validate the reliability of the results. Results:A total of 304 098 reports of adverse events during pregnancy were obtained from the FAERS and CVAR databases. Among them, 5 028 reports were related to tetracyclines, including 1 026 reports of congenital malformations in offspring, involving congenital malformations of musculoskeletal system, other digestive system, and other congenital malformations. Signal detection results suggested that tetracyclines may be a risk signal for above congenital malformations in offspring. The DEEP data included 411 936 pregnant women. After PSM, 240 pregnant women exposed to tetracyclines were included. The results showed no significant association between the first-trimester tetracyclines exposure and congenital malformations in offspring (a RR=0.75, 95% CI: 0.26-2.17), sensitivity analysis also showed no correlation. Conclusions:Data mining from the FAERS and CVAR databases suggests a potential association between tetracyclines use during pregnancy and congenital malformations in offspring. However, the DEEP data study shows no significant correlation.

Long-term burden of illness and associated medication usage make osteoporosis(OP) a common complication of respiratory diseases. The pathogenic risk factors and treatment strategies for respiratory diseases related OP are similar to primary OP. However, due to differences in the pathogenesis of each disease, there are distinctions in the characteristics of bone loss and treatment approaches. Therefore, targeted diagnostic and therapeutic plans need to be formulated. This article provides a comprehensive review of secondary OP caused by common respiratory diseases in terms of epidemiological characteristics, related risk factors or possible mechanisms, changes in bone metabolic indexes or characteristics of bone damage, and progress in diagnosis and treatment. The aim of this review is to offer insights into the prevention and treatment of secondary OP related to respiratory diseases and promote the development of a multidisciplinary collaborative approach.

Objective:To investigate the correlation between hearing loss and microvascular complications in diabetes.Methods:This cross-sectional study conducted the data from 572 patients with diabetes hospitalized in the Endocrinology Department of the General Hospital of Southern Theater Command from September 2022 to July 2023. All participants underwent electrical audiometry and acoustic immittance in the ENY department. Based on the audiometric results, participants were categorized into normal hearing group and hearing loss group. Additionally, 572 non-diabetic patients from the outpatient department were enrolled as the non-diabetic group. The general information and laboratory results were collected and compared using t test, rank sum test or χ2 test. Binary logistic regression analysis was used to evaluate the association of diabetic hearing loss with diabetic kidney disease(DKD), diabetic retinopathy (DR), and diabetic peripheral neuropathy (DPN). Results:Among 572 patients with diabetes, 429 suffered from hearing loss and 143 were normal. χ2 test showed significant differences in combined DKD and DPN between two groups, but not in DR. Multivariate binary logistic regression analysis identified DKD and DPN as risk factors for hearing loss, but no correlation was found with DR. Conclusion:Diabetic patients with DKD or DPN should be monitored for potential hearing loss. Early screening and treatment are crucial to prevent severe hearing impairment.

Objective:To establish a hyperuricemia rat model through the high temperature-humidity treatment, and monitor its vital signs and biochemical indicator characteristics, as well as observe the changes of renal histomorphology and ultrastructure.Methods:Male SD rats were randomly divided into control(CON) group, potassium oxonate(PO) group and high temperature-humidity(HTH) group, 6 rats each. The experiment lasted for 6 consecutive weeks. Rats from PO group was given 250 mg/kg PO by gavage every day. The rats from HTH group were treated with a special thermostatic incubator for one hour each day after gavaging 250 mg/kg PO. Serum uric acid, creatinine and other indicators were detected every 2 weeks. After 6 weeks, the kidney tissues were collected. The morphological changes and urate crystal deposition of kidney tissues were observed by hematoxylin-eosin staining, Masson′s trichrome staining and gomori staining, while the ultramicrostructural changes of kidney were observed by transmission electron microscope.Results:Two weeks after the experiment, the average serum uric acid values of PO group and HTH group increased significantly, HTH group was higher than PO and CON groups[(133.9±17.8), (107.6±12.4), and (85.7±4.1) μmol/L, P=0.001]. And after 6 weeks, the HTH group was still higher than the other two groups[(115.1±27.8), (82.7±13.9), and (72.9±17.8) μmol/L, P=0.008). The average serum creatinine in HTH group was slightly higher than that in PO group and CON group at 6 weeks[(46.2±4.7), (38.1±6.0), and (28.3±6.3) μmol/L, P=0.001]. Light microscope showed partial renal tubular dilatation in PO group, but renal tubular epithelial cells swelling and inflammatory cells infiltration were more significant in HTH group. The ultrastructural changes such as glomerular podocyte swelling were found in HTH group by transmission electron microscope. Conclusion:In this study, we had successfully established a hyperuricemia rat model by simulating the high temperature-humidity environment combined with potassium oxyzinate after 2 weeks of experiment. After 6 weeks of modeling, it was found that the high temperature-humidity induced rat models possessed a relatively higher and stabler serum uric acid level than that of the traditional chemical medicine induced rats. The method can be applied to the research of pathogenesis and pharmacotherapy of hyperuricemia caused by high temperature-humidity environment.

Objective To investigate the clinical outcomes of patients with locally advanced uterine cervical cancer (UCC) treated by 3-dimensional high dose rate-intracavitary brachytherapy (3D HDR-ICBT) combined with complementary applicator-guided external beam radiotherapy (EBRT).Methods A total of 120 patients pathologically diagnosed with locally advanced UCC (tumors with a maximum diameter≥6 cm or ≥5 cm complicated with eccentric tumor growth) treated with concurrent chemoradiotherapy (CCRT) from June 2010 to June 2015 were recruited.Five fractions of 3D HDR-ICBT combined with complementary applicator-guided external beam radiotherapy were performed.The prescribed dose for HR-CTV and IR-CTV was 7 Gy (D9o) and 5-6 Gy (D90).The rectum,sigmoid colon,bladder and adjacent small intestine were delineated as the organs at risk.Intensity-modulated radiation therapy (IMRT) was used for EBRT (45 Gy/ 25f) combined with cisplatin-based chemotherapy every three weeks (75 mg/m2).Results The median follow-up time was 46 months (14-96 months).The 5-year local control rate (LCR),disease-free survival (DFS),and overall survival (OS) were 92.8％,76.6％ and 81.0％,respectively.The incidence rate of grade Ⅰ-Ⅱ genitourinary and gastrointestinal acute toxicities were 57.8％ and 14.6％,whereas 8.1％ and 2.9％ for grade Ⅲ toxicities.The incidence rate of later grade Ⅰ-Ⅱ genitourinary and gastrointestinal toxicities were 8.4％ and 5.3％,and 0.97％ and 1.3％ for grade Ⅲ late toxicities.Conclusions The combination of HDR-ICBT with an applicator-guided IMRT (ICBT+IMRT) yields low incidence of severe adverse events,relatively high LC and OS rate for locally advanced UCC.It is an efficacious comprehensive treatment of locally advanced bulky UCC.

OBJECTIVE: To explore the microsurgical techniques for insular glioma without damaging its surrounding normal structures. METHODS: We retrospectively analyzed 54 patients with insular gliomas who underwent microsurgical operation by trans-syvian fissure approach between May, 2003 and August, 2008 in Xiangya Hospital. We discussed the techniques in the operation and summarized how to protect the key blood vessels, distinguish and protect the surrounding normal structures. RESULTS: There were 36 complete removals,14 secondary complete removals, and 4 partial removals.Six patients had complications after the craniotomy who had temporal speech disorder (aphasia mostly began to recover about 10 days after the craniotomy),4 patients had opposite side paralysis worsening (3 recovered normally and 1 improved after 6 months),4 had light paralysis, and another 3 had paralysis and speech disorder. CONCLUSION The microsurgery by means of trans-syvian fissure approach can well expose the anatomical relation between tumor and its surrounding structures,so that we can remove the tumor and protect the surrounding normal tissues as much as we can.
