Objective:To investigate the effect of different administration methods of recombinant human prourokinase (rhPro-UK) during emergency percutaneous coronary intervention (PCI) on myocardial perfusion and prognosis of patients with acute ST segment elevation myocardial infarction (STEMI).Methods:The clinical data of 132 patients with STEMI who underwent emergency PCI in the Military Hospital of the 71st Army Group of the Chinese People′s Liberation Army from August 2017 to August 2022 were analyzed retrospectively. Among them, 66 patients treated with rhPro-UK injection after the guide wire passed through the coronary artery lesion, balloon dilation and stent placement were included in group A. The other 66 patients treated with rhPro-UK injection once after the guide wire passed through the coronary artery lesion were included in group B. The two groups were compared in terms of PCI conditions, target vessel perfusion status [corrected TIMI frame count (CTFC) and blood flow (thrombolysis in myocardial infarction, TIMI) grade], myocardial perfusion status [TIMI myocardial perfusion grade (TMPG), ST segment regression rate (STR) at 90 min after operation and the incidence of no reflow/slow flow (NR/SF)], cardiac function indicators [left ventricular end diastolic volume (LVEDV), left ventricular end systolic volume (LVESV) and left ventricular ejection fraction (LVEF)], the incidence of major adverse cardiovascular events (MACE), and the incidence of bleeding events.Results:There were no statistically significant differences between the two groups in terms of the distribution of culprit blood vessels, intubation methods, and number of stents implanted ( P>0.05). After treatment, the proportion of TIMI blood flow grade 3 in the group A was higher than that in the group B:99.97% (64/66) vs. 87.88% (58/66). CTFC of the two tgroups decreased, and CTFC of group A was lower than that of group B: (23.49 ± 4.27) frames vs. (27.14 ± 4.83) frames ( P<0.05). The proportion of TMPG grade 3 in group A was significantly higher than that in group B: 95.45% (63/66) vs. 83.33% (55/66)( P<0.05). STR in group A was significantly higher than that in group B: 95.45% (63/66) vs. 83.33% (55/66)( P<0.05). The incidence of NR/SF in group A was lower than that in group B: 3.03% (2/66) vs. 14.29% (10/66)( P<0.05). There were no statistically significant differences in LVEDV or LVESV between the two groups before and after treatment ( P>0.05). After 1 month of treatment, LVEF of the two groups increased, and LVEF of group A was higher than that of group B: (71.08 ± 6.38) % vs. (66.24 ± 6.49) % ( P<0.05). After treatment, the incidence of MACE in group A was lower than that in group B: 6.06%(4/66) vs. 13.64%(9/66) ( χ2 = 2.13, P = 0.144). There was no statistically significant difference in the incidence of bleeding events between the two groups ( P>0.05). Conclusions:For patients with STEMI undergoing PCI, fractional injection of rhPro-UK can better improve myocardial perfusion, reduce the incidence of MACE, and effectively improve the prognosis, compared with one-time injection of rhPro-UK.

Objective:To investigate the levels of osteoporosis-related biomarkers in individuals with subclinical hypothyroidism complicated by type 2 diabetes mellitus.Methods:A cross-sectional study. From January 2021 to June 2022, 40 patients with subclinical hypothyroidism, 40 patients with type 2 diabetes, 40 patients with type 2 diabetes complicated with subclinical hypothyroidism, and 40 individuals receiving physical examination in Shanxi Bethune Hospital were selected as subjects in this study. The glucose and lipid metabolism indexes and bone metabolism indexes of the subjects were detected, and the differences and correlations of the metabolic indexes among the groups were analyzed by t-tests, nonparametric tests or correlation analysis. Results:Compared with healthy group, beta C-terminal cross-linked telopeptides of type Ⅰ collagen (β-CTX) level in type 2 diabetes group was higher [(344.60±125.61) vs (227.56±68.33) pg/ml] ( t=-5.176, P<0.001), osteocalcin (OC) and total procollagen type 1 aminoterminal peptide (t-PINP) were both lower [(15.76±4.70) vs (28.02±5.83)ng/ml, (43.49±13.63) vs (59.58±15.80) ng/ml] ( t=10.352, t=4.874, P<0.001). The β-CTX level in type 2 diabetes patients complicated with hypothyroidism was higher than that in patients with simple subclinical hypothyroidism [(380.51±122.22) vs (212.41±44.17) pg/ml] ( t=-8.180 ,P<0.001), but the levels of OC and t-PINP were both lower [(13.67±4.06) vs (26.12±4.55) ng/ml, (38.76±9.53) vs (61.50±12.31) ng/ml] ( t=12.897, P<0.001); but there was no significant difference in the three biomarkers between patients with type 2 diabetes mellitus complicated by subclinical hypothyroidism and those with type 2 diabetes mellitus alone. [β-CTX: (380.51±122.22) vs (344.60±125.61) pg/ml, OC: (13.67±4.06) vs (15.76±4.70) ng/ml, t-PINP: (38.76±9.53) vs (43.49±13.63) ng/ml] ( t=1.296,1.890,-1.799 ,all P>0.05). In the patients with type 2 diabetes mellitus complicated by subclinical hypothyroidism, the β-CTX was positively correlated with fasting blood glucose (FBG) and glycosylated hemoglobin (HbA1c)( r=0.293,0.487,all P<0.05), while OC and t-PINP were negatively correlated with FBG and HbA1c ( r=-0.560,-0.502,-0.289,-0.326, P<0.05). Conclusion:Changes of serum osteoporosis-related biomarkers in subclinical hypothyroidism patients with type 2 diabetes indicate the increased risk of osteoporosis in those patients.

Objective:This study aimed to explore the effect of Vaspin on adipose tissue macrophage polarization and its underlying mechanism.Methods:Fifty male SD rats, aged 8 weeks, were chosen and randomly allocated into three groups: the normal control(NC), the type 2 diabetes(T2DM), and various concentrations of Vaspin intervention(V1: 480 ng/kg, V2: 960 ng/kg, V3: 1 440 ng/kg). Vaspin was administered via intraperitoneal injection for 8 weeks. Glucose tolerance and insulin sensitivity were evaluated via intraperitoneal glucose tolerance test(IPGTT), intraperitoneal insulin tolerance test(IPITT) and hyperinsulinemic-euglycemic clamp. Adipose tissue inflammation and macrophage polarization were assessed using immunofluorescence, RT-PCR and western blotting.Results:After 8 weeks of intervention, there were no statistically significant differences in body weight and blood lipid levels among groups. IPGTT, IPITT, and hyperinsulinemic-euglycemic clamp experiments demonstrated that Vaspin intervention improved blood glucose and insulin sensitivity, exhibiting a dose-dependent manner( P<0.05). IF and RT-PCR showed that Vaspin downregulated the expression of CD11c, IL-1β, and TNF-α in eWAT, while upregulating the expression of CD206, IL-10, and PPARγ, which correlated with Vaspin concentration( P<0.05). ELISA revealed that Vaspin intervention reduced the concentrations of IL-1β and TNF-α in serum, while increasing the concentration of IL-10( P<0.05). Western blotting demonstrated that Vaspin downregulated iNOS protein expression, while upregulating Arg1, p-Akt, and PPARγ expression in a dose-dependent manner( P<0.05). Conclusion:Vaspin promotes M2 polarization of adipose tissue macrophages via PPARγ pathway, leading to reduced inflammation and improved insulin sensitivity in T2DM rats.

Objective:The purpose of this study is to explore the clinical characteristics of Coronavirus Disease 2019 (COVID-19) in patients with type 2 diabetes mellitus (T2DM), and analyze the risk factors for adverse outcomes.Methods:2 052 patients diagnosed with COVID-19 who were hospitalized in Shanxi Bethune Hospital between December 1, 2022 and March 20, 2023 were included. They were divided into diabetes group ( n=70) and non-diabetes group ( n=1 982) according to the presence or absence of comorbid T2DM. The two groups were matched at 1:1 via propensity score matching. Clinical characteristics and laboratory examination results of the two groups were compared. According to the outcomes during hospitalization, the two groups were further divided into two subgroups respectively. Univariate analysis and subsequent binary Logistic regression was used to analyze the risk factors of adverse outcomes in patients with COVID-19 and type 2 diabetes. Results:After the propensity score matching, the most common comorbid condition in diabetes group and non-diabetes group was hypertension. The proportion of patients with severe or critical disease in diabetes group was higher compared with non-diabetes group. The levels of hemoglobin A1c (HbA1c), fasting blood glucose (FBG), blood urea, IL-4, IL-6, IL-10, IFN-γ and TNF-α were significantly higher in the diabetes group ( P<0.05). Logistic regression analysis within the diabetes group showed that hypertension ( OR=3.640, 95% CI: 3.156 to 4.290), FBG>11 mmol/L ( OR=3.283, 95% CI: 1.416 to 7.611), HbA1c>10% ( OR=2.718, 95% CI: 1.024 to 7.213) were independent risk factors for adverse outcomes in patients with COVID-19 and type 2 diabetes(all P<0.05). Conclusions:Compared with the non-diabetes group, patients with COVID-19 and T2DM have worse inflammatory response and higher levels of inflammatory cytokines. The elevated levels of FBG and HbA1c are related to the adverse outcome in patients with COVID-19 and T2DM.

Objective:To evaluate the clinical relevant effect of hospital-wide blood glucose management in perioperative cholelithiasis patients with type 2 diabetes.Methods:The subjects of the study were patients with type 2 diabetes mellitus complicated with cholelithiasis who were treated at the Baiqiu'en Hospital in Shanxi from September 2022 to October 2023. The patients were divided into hospital-wide blood sugar management group and conventional treatment group, according to different blood glucose management they received. The differences in preoperative blood glucose control, length of stay, postoperative complications, and hospitalization expenses between the two groups were compared.Results:Compare based on the median (quartiles) of the observed indicators, patients with cholelithiasis who underwent hospital-wide blood glucose management based on insulin pumps had a higher proportion of time in range [72.00(70.21, 82.90)% vs. 64.80 (61.55,70.50)%, P<0.001)], lower average blood glucose level [9.00 (8.55, 10.44) mmol/L vs. 11.50 (10.50, 12.50) mmol/L, P<0.001], and shorter hospital stay [8.00 (7.00,13.00) days vs. 10.00 (8.00, 12.00) ) days, P<0.05]. Moreover, the incidence of postoperative complications was lower [5(11.11)% vs. 15(33.33)%, P<0.05], and hospitalization expenses were lower [16 535.34 (14 271.44, 29 569.23) yuan vs. 18 633.85 (17 482.66) yuan , 22 855.02) yuan, P<0.05] in patients who received hospital-wide blood glucose management. Conclusion:Hospital-wide blood glucose management based on insulin pumps showed favorable effects in the perioperative clinical application in cholelithiasis patients with type 2 diabetes, and could contribute to shortening the average length of stay, reducing hospitalization costs, and reducing postoperative complications.

In recent years,researchers have shown widespread attention in the impact of commonly used clinical anesthetics on overall physiological health by influencing mitochondrial quality.These widely used anesthetics can alter mitochondrial characteristics in several ways,such as modifying mitochondrial morphology and dynamics,affecting mitochondrial function and metabolism,and altering the expression of mitochondrial proteins.These changes have a direct or indirect effect on clinical outcomes during the peri-operative period.Either beneficial or detrimental consequences are decided by multiple factors,such as the type and dosage of anesthetic used,the timing of administration,and the patient's condition.This review comprehensively presents the effects of different types of anesthetic drugs,including intravenous anesthetics,inhalational anesthetics,analgesic,and local anesthetics,on the mitochondria quality of tissue cells and their potential mechanisms,which can facilitate selecting safer anesthesia protocols,minimizing postoperative complications,optimizing patients'postoperative recovery,developing new therapeutic strategies,and opti-mizing perioperative management.

Objective:Through meta-analysis, the association of three common adipokines (leptin, adiponectin, and chemerin) with bone nutrition of senile osteoporosis (SOP) in China was systematically evaluated.Methods:CNKI, CBM, VIP, Wanfang, PubMed, Web of Science, Embase, Cochrane Library, and other databases were searched for articles published from the establishment of the database to July 30, 2022. After literature screening, data extraction, and quality evaluation of the included studies were independently conducted by two researchers, a meta-analysis was performed using RevMan5.4 and Stata17.0 softwares.Results:A total of 13 studies in the Chinese population were included, including 897 patients with SOP and 673 elderly with normal bone mineral density . The results of the meta-analysis showed that compared with the control group, the serum leptin levels were significantly lower ( MD -2.64, 95% CI -4.04 to -1.23, P < 0.001), chemerin levels were significantly higher ( MD 25.23, 95% CI 14.57 to 35.90, P < 0.001), and adiponectin levels were not significantly different ( MD -0.55, 95% CI -2.26 to 1.17, P > 0.05) in SOP patients. After subgroup analysis according to the measurement method, leptin levels remained lower in SOP patients than in the control group. Conclusions:Compared with the control group, leptin levels were lower and chemerin levels were higher in SOP patients. Therefore, dysregulation of adipokines may play an important role in the occurrence and development of SOP, and regulation of adipokine levels and functions may play a role in the treatment of SOP and the improvement of bone nutrition as a nutritional intervention.

Objective:To analyze and compare the effects of conventional treatment and the dynamic 3C therapy, continuous glucose monitoring system, and on outcomes, length of hospital stay and medical costs in patients with type 2 diabetes mellitus.Methods:A total of 122 type 2 diabetes mellitus patients who visited the Department of Endocrinology of Shanxi Baiqiu'en Hospital between June 2022 and December 2022 were selected and randomized at 1:1 into the control group and the experimental group using the randomized numerical table method. The t-test and non-parametric test were used as appropriate to compare the glycemic control, length of hospital stay and medical costs of the two groups.Results:Before treatment, there was no significant difference in the indicators for blood glucose levels and fluctuations between the two groups ( P>0.05). After treatment, the glycosylated hemoglobin, fasting plasma glucose, and 2-hour postprandial blood glucose decreased in both groups. Moreover, the glycosylated hemoglobin, fasting plasma glucose, and 2-hour postprandial blood glucose showed more significant decreases in the experimental group compared with the control group after treatment. The glycemic variability indicators, including the time out of range, standard deviation of blood glucose, and the largest amplitude of glycemic excursion, decreased after treatment in both groups. The time in range increased after treatment. After treatment, the standard deviation of blood glucose and the largest amplitude of glycemic excursion in the experimental group were lower than those in the control group, and the length of hospital stay in the experimental group was shortened (all P<0.05). Conclusion:3C therapy contributes to better glycemic control and shorter hospital stay in patients with type 2 diabetes mellitus.

Objective:To explore the effects of different blood glucose management modes on self-management ability and glucose and lipid metabolism in patients with type 2 diabetes mellitus (T2DM) based on the WeChat platform.Methods:240 patients with T2DM were selected in Taiyuan Central Hospital from January to June 2020 for the study. They were randomly divided into general management groups, medical care management groups, peer management groups, and medical care and peer co-management groups using random number table, with 60 cases in each group. The general management group received routine outpatient follow-up. The medical care management group, peer management group, and medical care and peer management group established WeChat groups for management, respectively. Each group′s self-management ability and glucose and lipid metabolism indexes were compared before and after six months of intervention. t-test or nonparametric tests were used to compare. Results:After the intervention, self-management abilities such as diet, exercise, blood glucose monitoring, medication compliance, foot care, smoking and fasting blood glucose (FBG), and glycosylated hemoglobin (HbA 1c) were improved in the four groups (all P<0.05). The medical care management, peer management, and medical care and peer co-management groups were further improved than the general group (all P<0.05). Except for smoking, the above medical care and peer co-management group indicators were statistically different from those of the separate medical care management and peer management group (all P<0.05). Triacylglycerol (TG) of the four groups were improved compared with the previous [1.9(1.2, 2.7) compared with 2.3(1.6, 3.5)mmol/L, 1.4(1.2, 2.1) compared with 2.2(1.6, 3.2)mmol/L, 1.6(1.1, 2.0) compared with 2.2(1.4, 3.2)mmol/L, 1.5(1.0, 2.1) compared with 2.4(1.3, 3.1)mmol/L] (all P<0.05), and after the intervention, the total cholesterol (TC) of the four groups was also improved compared with that before the intervention [(4.7±0.9) compared with (5.1±1.2)mmol/L, (4.2±1.1) compared with (5.2±1.2)mmol/L, (4.3±1.1) compared with (5.4±1.3)mmol/L, (4.2±1.1) compared with (5.0±1.4)mmol/L] (all P<0.05), and TG and TC of the medical care management, peer management, and medical care and peer co-management groups were lower than those of the general group (all P<0.05). Conclusion:Based on the WeChat platform, the management mode of medical care and peer co-management is conducive to T2DM patients′ better self-management and blood glucose control.

Objective:To investigate the relationship between blood glucose fluctuation and carotid intima-media thickness (CIMT) in newly diagnosed patients with type 2 diabetes mellitus (T2DM) and the predictive value of betatrophin.Methods:A total of 180 newly diagnosed T2DM patients in Taiyuan Central Hospital from June 2018 to December 2019 were included for the study. And they were divided into normal intima-media group (81 cases), intima-media thickening group (60 cases) and plaque formation group (39 cases) according to the results of carotid ultrasound. The body test indexes, glucose and lipid metabolism indexes, blood glucose fluctuation and betatrophin level were compared among the three groups, and the correlation of these indexes with CIMT and risk factors of CIMT were analyzed.Results:The mean and maximal amplitude of glycemic excursions (AGE) in the plaque formation group and intima-media thickening group were significantly higher than those in the normal intima-media group [(5.08±0.62), (4.06±0.54) vs (3.17±0.41) mmol/L and (5.20±0.72), (4.26±0.54) vs (3.34±0.59) mmol/L] (all P<0.05), and these indexes in the plaque formation group were significantly higher than the intima-media thickening group (all P<0.05). Betatrophin levels in intima-media thickening group and plaque formation group were significantly higher than those in normal intima-media group [(423.35±76.24) and (490.68±97.84) vs (358.29±92.27) ng/L] (both P<0.05). Hip circumference and triglyceride (TG) in plaque formation group were obviously higher than those of the normal intima-media group and intima-media thickening group [(103.5±6.3) vs (97.6±7.0), (99.5±7.4) cm and 2.99 (1.32, 3.92) vs 1.70 (1.21, 2.39), 1.84(1.43, 2.93) mmol/L] (all P<0.05), and waist circumference, systolic blood pressure, fasting blood glucose (FBG), total cholesterol (TC), insulin resistance of homeostasis model assessment (HOMA-IR) levels in plaque formation group were significantly higher than those in normal intima-media group [(94.0 (86.0, 102.0) vs 88.0 (82.5, 94.0) cm, (136.2±18.0) vs (125.9±15.3) mmHg, 10.16 (8.43, 13.23) vs 8.49 (6.98, 9.97) mmol/L, (6.31±0.90) vs (4.99±0.99) mmol/L, 4.90 (3.50, 7.13) vs 2.77 (1.32, 5.07)] (all P<0.05). CIMT was positively correlated with waist circumference, hip circumference, systolic blood pressure (SBP), FBG, TC, TG, HOMA-IR, betatrophin, the mean and maximal AGE, blood glucose fluctuation coefficient (BGFC) (all P<0.05), and it was negatively correlated with time in range (TIR) ( P<0.05). The mean and maximal AGE, TC, TG and betatrophin were independent risk factors of CIMT (all P<0.05). Conclusion:Blood glucose fluctuation is closely related to CIMT in patients with T2DM, and betatrophin is expected to be an early predictor of diabetic macroangiopathy.
