ObjectiveTo investigate the triglyceride-glucose (TyG) index and the level of serum homocysteine (Hcy) in association with the incidence of stroke in type 2 diabetes mellitus (T2DM) patients. MethodsBased on the chronic disease risk factor surveillance cohort in Pudong New Area, Shanghai, excluding those with stroke in baseline survey, T2DM patients who joined the cohort from January 2016 to October 2020 were selected as the research subjects. During the follow-up period, a total of 318 new-onset ischemic stroke patients were selected as the case group, and a total of 318 individuals matched by gender without stroke were selected as the control group. The Cox proportional hazards regression model was used to adjust for confounding factors and explore the serum TyG index and the Hcy biochemical indicator in association with the risk of stroke. ResultsThe Cox proportional hazards regression results showed that after adjusting for confounding factors, the risk of stroke in T2DM patients with 10 μmol·L⁻¹-¹ and Hcy>15 μmol·L⁻¹ was 1.532 times (95%CI: 1.017‒2.309 times, P=0.041) and 1.738 times (95%CI: 1.119‒2.699 times, P=0.014) higher respectively, compared to T2DM patients with Hcy≤10 μmol·L⁻¹. T2DM patients with TyG>9.074 had 1.396 times higher risk of stroke (95%CI: 1.091‒1.787, P=0.008) compared to those with TyG≤9.074. The study found that urea and α1-antitrypsin (α1-AT) were independent risk factors for the incidence of stroke in T2DM patients. For every unit increase in urea andα1-AT, the risk of stroke in T2DM patients increased by 233.6% (HR=3.336, 95%CI: 1.588‒7.009, P=0.001) and 11.3% (HR=1.113, 95%CI: 1.028‒1.205, P=0.008), respectively. Cumulative risk curves showed that Hcy>10 μmol·L⁻¹ and TyG>9.074 accelerated the time to stroke occurrence in T2DM patients. ConclusionElevated levels of Hcy>10 μmol·L⁻¹ and a higher TyG index are risk factors for stroke in T2DM patients. Effective interventions for Hcy and TyG should be conducted for diabetic patients to reduce the incidence of stroke.

Objective To assess the value of cone-beam computed tomography (CBCT) in evaluating the response of unresectable liver cancer to transarterial chemoembolization (TACE). Methods A total of 55 unresectable liver cancer patients with 90 lesions who received TACE at the First People’s Hospital of Liangshan Yi Autonomous Prefecture between July 2021 and July 2023 were enrolled in the study. The response to TACE was evaluated using the modified Response Evaluation Criteria in Solid Tumors one month post-treatment. The value of lesion diameter, volume, and density on CBCT images in predicting the response to TACE was assessed using the area under the receiver operating characteristic curve. Results Of the 55 patients treated with TACE, 26 achieved complete response, 17 achieved partial response, 9 showed stable disease, and 3 had progressive disease. Of the 90 lesions, 48 achieved complete response, 20 achieved partial response, 17 showed stable disease, and 5 had progressive disease. On CBCT images, the mean diameter, volume, and density of lesions with complete and non-complete responses were (20.9 ± 9.9) mm, (1719.3 ± 777.9) mm³, and (143.7 ± 87.9) HU, versus (10.9 ± 7.7) mm, (890.0 ± 327.4) mm³, and (38.8 ± 33.3) HU, respectively, with significant differences between the two groups (t=10.6, 79.8, and 65.5; all P < 0.01). One month post-treatment, CT scans displayed no enhanced areas in lesions with complete response and visible enhanced areas in lesions with non-complete response, with mean lesion diameter and density of (14.1 ± 6.2) mm and (78.8 ± 30.3) HU, respectively. In addition, the areas under the receiver operating characteristic curves of lesion diameter, volume, and density on CBCT images were 0.935, 0.955, and 0.981, respectively, in distinguishing between complete and non-complete responses following TACE. Using a cut-off value of 82.5 HU for predicting response to TACE, the lesion density had sensitivity, specificity, positive predictive value, and negative predictive value of 95.5%, 100.0%, 100.0%, and 95.0%, respectively. Conclusion CBCT is effective in predicting the short-term response of liver cancer to TACE.

Objective To assess the nutritional status of vitamin D and associated factors among adults of six ethnic minority groups native to Yunnan Province,and provide evidence for policy making.Methods Between May 2019 and August 2020,a total of 690 adults were selected from Jinuo,Bulang,Jingpo,Deang,Achang and Pumi ethnic groups according to the sex and age composition in the 6th national census.A questionnaire survey and an anthropometric examination were conducted by trained health workers,and serum 25(OH)D levels were determined with high-performance liquid chromatography-tandem mass spectrometry.Results The median of serum 25(OH)D was 28.7(P25～P75∶24.3～33.8)ng/mL,and the prevalence of vitamin D sufficiency,insufficiency and deficiency were 44.2%、47.5%and 8.3%,respectively.There were significant differences in serum 25(OH)D levels among the six ethnic groups(χ2=139.29,P<0.01).Multivariate logistic regression showed that ethnic groups living in higher latitude areas(Pumi,Jingpo,Deang,and Achang),women,and those whose BMI≥24.0 were more likely to be vitamin D insufficient or deficient.Conclusion More than half of the ethnic adults suffer from vitamin D malnutrition which also varies across ethnicities.Further surveillance and interventions among key areas and populations are needed.

Depression is a frequently-seen mental disorder that profoundly affects the survival and quality of life of individuals.Present clinical medicine therapies for depression are not fully efficacious and novel therapeutic agents and targets remain necessary.Bupleuri Radix-Paeoniae Radix(BR-PRA),an essential and crucial compo-nent of traditional antidepressant compound,possesses the beneficial effect of lowering toxicity and amplifying the antidepressant effect when utilized in combination.The underlying mechanisms of these synergistic effects may involve the suppression of inflammation and oxidative stress,the regulation of monoamine neurotransmitters,brain-derived neurotrophic factors,the modulation of the hypothalamus-pituitary-adrenal axis,and the metabolism of various amino acids and energy.This article summarizes the synergistic effects and antidepressant pharmacological effects of BR-PRA herb-pair,thereby providing valuable insights into the potential advantages of this combination and its potential mechanisms of antidepressant action.

The birth of an improved TNM staging system heralds the changes that will follow in clinical practice and scientific research.

Objective To explore the clinical diagnostic value of peripheral blood procalcitonin(PCT)and neutrophil lymphocyte ratio(NLR)levels in elderly patients with strangulated inguinal hernia.Methods The clinical data of 112 elderly patients with acute incarcerated inguinal hernia from January 2019 to December 2022 were retrospectively analyzed,and were divided into strangulated group and non-strangulated group according to the intraoperative exploration.Multivariate Logistic regression analysis of risk factors of strangulated inguinal hernia in the elderly.Evaluation of PCT and NLR levels in peripheral blood by ROC curve in the clinical diagnosis of strangulated inguinal hernia in the elderly.Results The NLR and PCT in the strangulation group[(4.54±1.67)and(6.74±2.42)ng/ml]were higher than those in the non-strangulation group[(3.78±1.48)and(4.97±2.53)ng/ml](P＜0.05).Multivariate Logistic regression analysis showed that preoperative NLR and PCT levels were risk factors for strangulated inguinal hernia in the elderly(P＜0.05).Both NLR and PCT have high clinical diagnostic value for strangulated inguinal hernia in the elderly(AUC＞0.7),and the combined detection of NLR and PCT can improve the diagnostic efficiency(AUC=0.792).Conclusion PCT and NLR levels in peripheral blood have high clinical diagnostic value for strangulated inguinal hernia in the elderly,and combined detection of NLR and PCT can improve the diagnostic efficiency.

Background::Cardiovascular disease (CVD) has emerged as the leading cause of death from prostate cancer (PCa) in recent decades, bringing a great disease burden worldwide. Men with preexisting CVD have an increased risk for major adverse cardiovascular events when treated with androgen deprivation therapy (ADT). The present study aimed to explore the prevalence and risk evaluation of CVD among people with newly diagnosed PCa in China.Methods::Clinical data of newly diagnosed PCa patients were retrospectively collected from 34 centers in China from 2010 to 2022 through convenience sampling. CVD was defined as myocardial infarction, arrhythmia, heart failure, stroke, ischemic heart disease, and others. CVD risk was estimated by calculating Framingham risk scores (FRS). Patients were accordingly divided into low-, medium-, and high-risk groups. χ2 or Fisher’s exact test was used for comparison of categorical variables. Results::A total of 4253 patients were enrolled in the present study. A total of 27.0% (1147/4253) of patients had comorbid PCa and CVD, and 7.2% (307/4253) had two or more CVDs. The enrolled population was distributed in six regions of China, and approximately 71.0% (3019/4253) of patients lived in urban areas. With imaging and pathological evaluation, most PCa patients were diagnosed at an advanced stage, with 20.5% (871/4253) locally progressing and 20.5% (871/4253) showing metastasis. Most of them initiated prostatectomy (46.6%, 1983/4253) or regimens involving ADT therapy (45.7%, 1944/4253) for prostate cancer. In the present PCa cohort, 43.1% (1832/4253) of patients had hypertension, and half of them had poorly controlled blood pressure. With FRS stratification, as expected, a higher risk of CVD was related to aging and metabolic disturbance. However, we also found that patients with treatment involving ADT presented an originally higher risk of CVD than those without ADT. This was in accordance with clinical practice, i.e., aged patients or patients at advanced oncological stages were inclined to accept systematic integrative therapy instead of surgery. Among patients who underwent medical castration, only 4.0% (45/1118) received gonadotropin releasing hormone antagonists, in stark contrast to the grim situation of CVD prevalence and risk.Conclusions::PCa patients in China are diagnosed at an advanced stage. A heavy CVD burden was present at the initiation of treatment. Patients who accepted ADT-related therapy showed an original higher risk of CVD, but the awareness of cardiovascular protection was far from sufficient.

Objective To observe the value of CT radiomics nomogram for predicting Ki-67 expression of thymus epithelial tumors.Methods Totally 163 patients with thymus epithelial tumor,including 114 patients in training set and 49 patients in validation set were retrospectively enrolled.The patients were further divided into low expression(＜50％)and high expression(≥50％)subgroups according to Ki-67 index.Multivariate logistic regression analysis was performed to screen independent predicting factors of Ki-67 expression in thymus epithelial tumors,and clinical-CT model was constructed.The optimal radiomics features were extracted and screened based on chest plain and venous phase enhanced CT images,respectively.Then radiomics modelplain and radiomics modelenhanced were constructed,and Radscoreplain and Radscoreenhanced were calculated,respectively.The nomogram model was constructed based on clinical-CT model,Radscoreplain and Radscoreenhanced.Receiver operating characteristic curves were drawn,and the area under the curves(AUC)were calculated to evaluate the efficacy of each model for predicting Ki-67 expression of thymus epithelial tumors.Results Patient's gender and enhanced CT value of lesion were both independent predicting factors of Ki-67 expression in thymus epithelial tumors(both P＜0.05).The AUC of clinical-CT model,radiomics modelplain,radiomics modelenhanced and nomogram model for predicting Ki-67 expression was 0.736,0.814,0.836 and 0.857 in training set,which was 0.746,0.746,0.750 and 0.799 in validation set,respectively.Conclusion CT radiomics nomogram could be used to predict Ki-6 7 expression of thymus epithelial tumors.

Objective:To examine the clinical value of rapid detection of drug-resistant bacteria by immunochromatography and the effects of rapid detection on the prognosis of patients with severe intra-abdominal infection complicated by carbapenem-resistant Enterobacteriaceae (CRE) bloodstream infection.Methods:This was a retrospective cohort study. We analyzed clinical data of 73 patients with severe abdominal infections with sepsis or septic shock complicated by CRE bloodstream infection admitted to the general surgery department of Jinling Hospital between February 2022 and February 2023. Patients were divided into a colloidal gold immunochromatographic assay (GICA) group (17 patients) and conventional testing group (56 patients) based on whether a GICA for CRE had been performed on the patients' first blood culture sample during the diagnosis and treatment process. There were no statistically significant differences between the GICA and conventional testing groups in age ([55.9±17.3] vs. [47.6±16.4] years), sex ([16 men vs. one woman ] vs. [41 men vs. 15 women]), median Charlson comorbidity index (3.0[2.0,4.0] vs. 3.0[2.0, 4.8]), septic shock (10 vs. 39), or acute kidney injury (8 vs. 40) (all P>0.05). Both groups routinely underwent traditional bacterial identification and drug susceptibility testing. Additionally, patients in the GICA group were tested directly for positive blood cultures using a GICA carbapenemase test kit. The main outcomes were mortality rates on Days 28 and 90 after the first identification of CRE bloodstream infection in both groups. We also compared the microbial clearance rate, duration of hospitalization and intensive care unit stay, and time from onset of CRE bloodstream infection to initiation of targeted and appropriate antibiotics between the two groups. Results:The rate of microbial clearance of bloodstream infection was significantly greater in the GICA group than in the conventional testing group (15/17 vs. 34/56 [60.7%], χ 2=4.476, P=0.034), whereas the 28-day mortality tended to be lower in the GICA than conventional testing group [5/17 vs. 44.6% [25/56], χ 2=1.250, P=0.264). The 90-day mortality (8/17 vs. 53.6% [30/56], χ 2=0.222, P=0.638), median duration of hospitalization (37.0 [18.0, 46.5] days vs. 45.5 [32.2, 64.8] days, Z=-1.867, P=0.062), and median duration of intensive care unit stay (18.0 [6.5, 35.0] days vs. 32.0 [5.0, 51.8] days, Z=-1.251, P=0.209). The median time between the onset of bloodstream infection and administration of antibiotics was 49.0 (38.0, 69.0) hours in the GICA group, which is significantly shorter than the 163.0 (111.8, 190.0) hours in the conventional testing group ( Z=-5.731, P<0.001). The median time between the onset of bloodstream infection and administration of appropriate antibiotics was 40.0 (34.0, 80.0) hours in the GICA group, which is shorter than in the conventional testing group (68.0 [38.2, 118.8]) hours; however, this difference is not statistically significant ( Z=-1.686, P=0.093). Conclusions:GICA can provide information on carbapenemase- producing pathogens faster than traditional drug sensitivity testing, enabling early administration of the optimal antibiotics. The strategy of 'carbapenemase detection first' for managing bacterial infection has the potential to improve prognosis of patients and reduce mortality rate.

Objective:To investigate the clinical effect of three different tissue flaps in repairing patients with orbital region tissue loss after enlarged resection of malignant tumors in the orbital region, as well as the indication.Methods:Retrospective analysis of data of patients with malignant tumors in the orbital region treated in the Department of Oral and Maxillofacial Trauma and Orthognathic Surgery, the First Affiliated Hospital of Xinjiang Medical University (Affiliated Stomatological Hospital) between January 2017 and December 2021. All patients underwent extensive resection of periorbital malignant tumors and enucleation of orbital contents, depending on defects in periorbital soft/hard tissues and orbital contents, temporalis myofascial flap combined with full thickness skin grafts (TMF-FTSG group), modified pectoralis major myocutaneous flap (PMMF group), and free anterolateral thigh flap (ALTF group) were used to repair the tissue defect. The wound healing and complications of the donor and recipient areas were followed up after operation, and degree of mouth opening in the TMF-FTSG group was compared at 3 months after operation and before operation. The University of Washington quality of life scale (UW-QOL) score was compared among the three groups before and 1 year after operation (a total of 12 items, each item was assigned from 0 to 100 points, the higher the score, the better the recovery). Statistical software SPSS 26.0 was used to analyze the data. The measurement data were expressed as Mean±SD, and the paired t-test was used to compare the preoperative and postoperative data within the group, the difference was statistically significant at a P value less than 0.05. Results:A total of 22 patients were enrolled. There were 8 patients in TMF-FTSG group, 4 males and 4 females, aged (68.3±9.7) years. There were 6 patients in PMMF group, 5 males and 1 female, aged (65.8±7.8) years. There were 3 males and 5 females in ALTF group, aged (63.8±5.4) years. There were 12 cases of squamous cell carcinoma, 8 cases of basal cell carcinoma and 2 cases of adenoid cystic carcinoma. The size of soft tissue defect after tumor resection in TMF-FTSG group, PMMF group and ALTF group was 4 cm×4 cm-7 cm×8 cm, 4 cm×5 cm-9 cm×9 cm and 5 cm×6 cm-14 cm×9 cm, respectively. And the size of flaps ranged from 5 cm×4 cm to 8 cm×9 cm, from 5 cm×7 cm to 10 cm×10 cm, and from 10 cm×6 cm to 20 cm×9 cm, respectively. All donor sites and 20 recipient sites recovered in stage Ⅰ, 2 recipient sites recovered in stage Ⅱ. The patients were monitored for a mean of (27.2 ±13.0) months. During the period of follow-up, one patient, reconstructed with PMMF, died 13 months after surgery due to local tumor recurrence, while the others did not experience metastasis or recurrence. In TMF-FTSG group, the mouth opening was (3.60±0.36) cm 3 months after operation and (3.84±0.15) cm before operation, with no significant difference ( P>0.05). The UW-QOL scores of appearance, mood and anxiety in the three groups 1 year after operation were higher than those before operation ( P<0.05), and the one year after operation’s scores of activity and shoulder were lower than those before operation ( P<0.05). The UW-QOL scores of pain and recreation in TMF-FTSG group one year after operation were higher than those before operation ( P<0.05), the other two groups were also higher than those before operation, but the difference was not statistically significant ( P>0.05). There was no significant difference in the UW-QOL scores of swallowing, chewing, speech, taste, and saliva in the three groups at one year after operation and before operation ( P>0.05). Conclusion:In the repair of tissue defects after operation of malignant tumors in the orbital region, three distinct types of tissue flaps can be utilized to repair tissue defects. TMF-FTSG has certain advantages for patients with minor bone defects, whereas ALTF and PMMF are more appropriate for patients with extensive tissue loss. PMMF is an effective method of repair for patients with a history of radiotherapy and poor vascular health in the recipient area.
