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.

ObjectiveTo evaluate the intervention effect of meteorological risk forecasting service on acute onset and medical expenses of chronic obstructive pulmonary disease（COPD） patients， and to provide scientific basis for the establishment of health management model for chronic obstructive pulmonary disease（COPD） patients. MethodsStudy subjects were recruited from chronic obstructive pulmonary patients aged ≥40 in Pudong New Area. Propensity score matching method was used to determine the intervention group and the control group. The control group received regular health education and follow-up management， and the intervention group was provided with meteorological and environmental risk forecasting services through WeChat， mobile phone short message service（SMS）and telephone. Finally， a total of2 589 subjects were included in the analysis， including 1 300 in the intervention group and 1 289 in the control group. General demographic data， past medical history and family history of COPD， COPD related knowledge and practice survey， COPD related symptom assessment， acute onset， health service utilization and medical expenses before and after intervention were collected through questionnaire survey. The differences of acute attack， health service utilization and related medical expenses between the two groups before and after intervention were compared to evaluate the intervention effect. ResultsIn terms of acute attacks， after intervention， the incidence of acute attacks in the intervention group was lower than that before intervention（χ²=52.901， P<0.001）， and the incidence of acute attacks in the groups with different intervention methods was lower than that before intervention （P<0.001）. WeChat had the best effect， decreasing the incidence by 14.4%， followed by mobile phone SMS SMS decreasing by 12.3%. In terms of utilization of health services， the outpatient rate due to acute attack was lower in the intervention group after intervention than that before intervention （χ²=7.129， P=0.008）， and the outpatient rate due to acute attack was lower in the subjects who received the forecast service through mobile phone SMS than that before intervention （χ²=4.675， P<0.001）. In terms of medical expenses， there was no significant difference between control group and intervention group with different intervention methods before intervention （P>0.05）. After intervention， the difference between the control group and the intervention group with different intervention methods was statistically significant （H=11.864， P<0.05）. The results of multiple comparisons showed that compared with the control group， the average annual medical expenses of patients receiving mobile phone SMS and telephone forecasting services after intervention were lower than those of the control group， and the difference was statistically significant （P<0.05）. ConclusionMeteorological risk forecasting service can reduce the acute onset of COPD， reduce the rate of consultation and medical expenses due to acute onset， and provide scientific basis for the basic COPD health management model.

Objective To explore the relationship between baseline urinary protein levels and the onset of chronic obstructive pulmonary disease (COPD). Methods A questionnaire survey, blood and urine sample collection, physical examination, and pulmonary function test were conducted among permanent residents over 40 years old in Pudong New Area, Shanghai. The subjects were divided into four groups based on the baseline urine albumin-to-creatinine ratio (ACR) quartiles (0~1.65 mg/g, 1.65~4.89 mg/g, 4.89~10.78 mg/g, and ≥10.78 mg/g). Cox regression analysis was used to explore the relationship between ACR levels and the incidence of COPD in middle-aged and elderly people. Results Among the 3 105 subjects, the median follow-up time was 3.212 years (P25~P75：3.102~3.473). 116 new cases of COPD were observed, with an incidence density of 10.423 per 1000 person-years. The incidence densities for COPD at four ACR levels were 7.922 per 1 000 person-years, 8.300 per 1 000 person-years , 11.419 per 1 000 person-years, and 13.843 per 1 000 person-years, respectively. Cox regression analysis revealed that as the ACR level increased, there was a rising trend in the incidence rate of COPD (χ²=4.396, P=0.036). After adjusting for gender, age, education level, occupational exposure to dust, history of childhood pneumonia, smoking, family history of COPD, central obesity, and hypertension, the risk of developing COPD was 2.499 times higher (95% CI: 1.460~4.276) for ACR levels ≥10.78 mg/g compared to the reference group with a baseline ACR level of 0~1.65 mg/g. Conclusion Elevated ACR levels in middle-aged and elderly population may increase the risk of COPD, and early monitoring of urine protein levels is beneficial for COPD prevention.

Objective:To investigate the role of an inflammatory microenvironment induced by Porphyromonasgingivalis ( P. gingivalis) in the occurrence of esophageal squamous cell carcinoma (ESCC) in mice. Methods:A total of 180 C57BL/6 mice were randomly divided into 6 groups, i.e. control group, P. gingivalis group, 4NQO group, 4NQO + P. gingivalis group, 4NQO + P. gingivalis + celecoxib group, and 4NQO + P. gingivalis + antibiotic cocktail (ABC, including metronidazole, neomycin, ampicillin, and vancomycin) group, with 30 mice in each group, using the random number table. All mice were normalized by treatment with ABC in drinking water for 2 weeks. In the following 2 weeks, the mice in the control group and the P. gingivalis group were given drinking water, while the other 4 groups were treated with 30 μg/ml 4NQO in the drinking water. In weeks 11-12, the mice in the P. gingivalis group, the 4NQO + P. gingivalis group, the 4NQO + P. gingivalis + celecoxib group, and the 4NQO + P. gingivalis + ABC group were subjected to ligation of the second molar in oral cavity followed by oral P. gingivalis infection thrice weekly for 24 weeks in weeks 11-34. In weeks 13-34, the mice in 4NQO + P. gingivalis+celecoxib group and 4NQO + P. gingivalis + ABC group were administered with celecoxib and ABC for 22 weeks, respectively. At the end of 34 weeks, gross and microscopic alterations were examined followed by RT-qPCR and immunohistochemistry to examine the expression profiles of inflammatory- and tumor-molecules in esophagi of mice. Results:At 34 weeks, 4NQO treatment alone did not affect the foci of papillary hyperproliferation, diseased area, and the thickness of the esophageal wall, but significantly enhanced the foci of hyperproliferation (median 1.00, P＜0.05) and mild/moderate dysplasia (median 2.00, P＜0.01). In addition, the expression levels of IL-6 [8.35(3.45,8.99)], IL-1β [6.90(2.01,9.72)], TNF-α [12.04(3.31,14.08)], c-myc [2.21(1.80,3.04)], pSTAT3, Ki-67, and pH2AX were higher than those in the control group. The pathological changes of the esophageal mucosa were significantly more overt in the 4NQO + P. gingivalis group in terms of the foci of papillary hyperproliferation (median 2.00), diseased area (median 2.51 mm 2), the thickness of the esophageal wall (median 172.52 μm), the foci of hyperproliferation (median 1.00, P＜0.05), and mild/moderate dysplasia (median 1.00, P＜0.01). In mice of the 4NQO + P. gingivalis group, the expression levels of IL-6 [12.27(5.35,22.08)], IL-1β [13.89(10.04,15.96)], TNF-α [19.56(6.07,20.36)], IFN-γ [11.37(8.23,20.07)], c-myc [2.62(1.51,4.25)], cyclin D1 [4.52(2.68,7.83)], nuclear pSTAT3, COX-2, Ki-67, and pH2AX were significantly increased compared with the mice in the control group. In mice of the 4NQO + P. gingivalis group, the diseased area, invasive malignant foci as well as pSTAT3 and pH2AX expression were significantly blunted by celecoxib. Treatment with ABC markedly reduced the papillary hyperproliferative foci, invasive malignant foci, and pSTAT3 expression but not pH2AX. Conclusions:P. gingivalis promotes the occurrence of esophageal squamous cell carcinoma in mice by inducing an inflammatory microenvironment primed with 4NQO induced DNA damage. Clearance of P. gingivalis with ABC or anti-inflammatory intervention holds promise for prevention of esophageal squamous cell malignant pathogenesis via blockage of IL-6/STAT3 signaling and amelioration of inflammation.

Objective:To compare and analyze the accuracy of the invasive glucose detecting device and the non-invasive glucose device(NeoGlu01)based on artificial intelligence(AI)algorithm in detecting peripheral blood glucose.Methods:A total of 96 diabetic voluntary patients were recruited from the community of Beijing district from December 2022 to March 2023.The Roche ACCU-CHECK? Guide invasive glucose device was used to detect the peripheral blood glucose of volunteers,and the NeoGlu 01 type of non-invasive glucose device was used to collect the signal of the finger,so as to obtain the blood glucose value that was calculated by AI algorithm at the same time.Pearson correlation analysis was adopted to analyze the detected blood glucose values of the two kinds of devices.Results:Both the peripheral blood glucose values of invasive glucose detecting device and the calculated AI values of NeoGlu01 type of non-invasive glucose device for 96 diabetic patients had favorable consistency with calibration value(R2=0.978,0.882,P<0.05),respectively.Both the detected values of peripheral blood glucose of invasive glucose detecting device and the calculated AI values of NeoGlu01 type of non-invasive glucose device were between 6.2 and 16.7 mmol/L for 96 diabetic patients,and the difference was no significant(P>0.05).Parkes error grid analysis,that referred to the values of peripheral blood glucose,indicated the two times of the results of the values of mean absolute relative difference(MARD)of total accuracy indicator of calculated AI value of non-invasive glucose device were respectively 11.05%and 11.44%,and both the accuracy rate and repeatability of that were favorable.Conclusion:The predictive blood glucose value of NeoGlu01 non-invasive blood glucose device has favorable consistency and accuracy with the detected value of invasive glucose detecting device in detecting peripheral blood glucose.

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.

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.
