ObjectiveTo analyze the incidence rate and mortality of acute myocardial infarction (AMI) and their changing trends among the registered residents in Xiaoshan District, Hangzhou City from 2017 to 2023, so as to provide references for formulating policies related to AMI prevention. MethodsThe morbidity and mortality data of AMI among the registered residents in Xiaoshan District from 2017 to 2023 were collected through the Hangzhou Chronic Disease and Death Cause Monitoring System. Software such as Excel 2019, SPSS 25.0 and Joinpoint 4.9.1.0 were used to calculate the incidence rate, mortality, and average annual percentage change (AAPC) of AMI. ResultsFrom 2017 to 2023, the average annual crude incidence rate, age-standardized incidence rate using China standard population (ASIRC), and the age-standardized incidence rate using World standard population (ASIRW) of AMI in Xiaoshan District were 48.25/100 000, 29.14/100 000, and 21.64/100 000, respectively, and, from which the AAPCs were 5.495%, 6.010%, and 6.533%, respectively, all showing an upward trend. The average annual crude mortality rate, the age-standardized mortality rate using China standard population (ASMRC), and the age-standardized mortality rate using World standard population (ASMRW) were 11.76/100 000, 6.52/100 000, and 4.71/100 000, respectively, from which the AAPCs were -9.669%, -10.433% and -9.615%, respectively, all showing a downward trend. The average annual crude incidence rate of AMI was higher in males (65.87/100 000) than that in females (31.31/100 000). Moreover, the average annual crude mortality rate of AMI was higher in males (14.08/100 000) than that in females (9.52/100 000), and the difference was statistically significant (all P<0.001) .After age grouping, the crude incidence rate of AMI among the residents aged 35-, 45-, 55-, and 65- years in Xiaoshan District from 2017 to 2023 showed an upward trend over time, with AAPCs of 16.993%, 17.149%, 8.523%, and 5.002%, respectively. While the crude mortality rate in residents aged 35-, 75-, and 85-102 years showed an decreasing trend over time, with AAPCs of -23.977%, -15.467%, and -17.415%, respectively, but there was no statistically significant difference in the trends in incidence rate and mortality of other age groups (all P>0.05). ConclusionThe situation of AMI prevention and control among the registered residents in Xiaoshan District is not optimistic, and targeted measures should be strengthened for the male residents aged ≥35 years old.

OBJECTIVE: To investigate the short-to-medium-term clinical efficacy of total hip arthroplasty(THA) with Pinnacle ES constrained liner in the treatment of femoral neck fractures(FNF) associated with lower limb neuromuscular disorders. METHODS: A retrospective analysis was conducted on 16 patients who underwent primary THA using Pinnacle ES constrained liner for FNF with lower limb neuromuscular disorders and had complete follow-up data, treated between January 2020 and January 2023. There were 7 males and 9 females, with a mean age of (68.42±3.58) years old ranging from 61 to 75 years old. Among them, 10 cases had left-sided fractures and 6 had right-sided fractures;based on the Garden classification, 11 cases were type Ⅲ and 5 cases were type Ⅳ. The affected limbs were complicated with sequelae of poliomyelitis (2 cases), Parkinson's disease (2 cases), and sequelae of cerebral infarction (12 cases). All operations were performed via a posterolateral approach. Prosthesis position was evaluated using imaging data. Hip function was assessed by the Harris hip score(HHS) and Merle D'Aubigne hip score. During the follow-up period, the occurrence of complications such as prosthetic dislocation, loosening, and infection was recorded. RESULTS: One patient died of advanced tumor 2 years after surgery, and the remaining 15 patients were followed up for 24 to 64 months with a mean of (34.8±5.5) months. The operation time ranged from 50 to 90 minutes with a mean of (75.56±8.15) minutes, and the blood loss ranged from 150 to 200 ml with a mean of (170.32±12.56) ml. All patients achieved primary wound healing after surgery. Intraoperatively, femoral calcar splitting occurred in 2 cases, which were treated with titanium cable binding;no neurovascular injuries were observed in any case. The mean HHS increased from (18.95±2.25) preoperatively to (88.02±2.42) at the last follow-up, and the mean Merle D'Aubigne Score increased from (3.05±0.06) preoperatively to (16.65±0.93) at the last follow-up. Postoperative follow-up X-rays showed good prosthetic position, and no complications such as dislocation, prosthetic loosening, periprosthetic fracture, or deep infection occurred during the follow-up period. CONCLUSION Total hip arthroplasty with Pinnacle ES constrained liner is effective in the treatment of femoral neck fractures associated with lower limb neuromuscular disorders. It can significantly improve hip function, reduce the postoperative prosthetic dislocation rate, provide good initial stability, and achieve satisfactory short-to-medium-term clinical efficacy.

ADC189 is a novel drug of cap-dependent endonuclease inhibitor. In our study, its antiviral efficacy was evaluated in vitro and in vivo, and compared with baloxavir marboxil and oseltamivir. A first-in-human phase I study in healthy volunteers included single ascending dose (SAD) and food effect (FE) parts. In the preclinical study, ADC189 showed potent antiviral activity against various types of influenza viruses, including H1N1, H3N2, influenza B virus, and highly pathogenic avian influenza, comparable to baloxavir marboxil. Additionally, ADC189 exhibited much better antiviral efficacy than oseltamivir in H1N1 infected mice. In the phase I study, ADC189 was rapidly metabolized to ADC189-I07, and its exposure increased proportionally with the dose. The terminal elimination half-life (T_1/2) ranged from 76.69 to 98.28 hours. Of note, food had no effect on the concentration, clearance, and exposure of ADC189. It was well tolerated, with few treatment-emergent adverse events (TEAEs) reported and no serious adverse events (SAEs). ADC189 demonstrated excellent antiviral efficacy both in vitro and in vivo. It was safe, well-tolerated, and had favorable pharmacokinetic characteristics in healthy volunteers, supporting its potential for single oral dosing in clinical practice.

OBJECTIVE: To explore risk factors for infections after arthroscopic rotator cuff repair, and improve the under standing for reducing infection. METHODS: Clinical data of 2 591 patients who underwent arthroscopic rotator cuff repair from January 2019 to January 2022 were retrospectively analyzed, including 1 265 males and 1 326 females, aged from 25 to 82 years old with an average age of (51.5±15.6) years old. They were divided into infection group(n=18) and uninfected group(n=2 573) according to whether or not patients had postoperative infection. Gender, age, smoking, diabetes, body mass index, local closure within 1 month before operation, operation time, preventive use of antibiotics, and internal fixation implantation between two groups were recorded. Univariate Logistic regression analysis screened factors associated with infections after arthroscopic rotator cuff repair. Theresultswere entered into the multivariate logistic regression analysis, screening the high risk factors for infections after arthroscopic rotator cuff repair. RESULTS: In 2 591 patients, 18 patients were infected after operation, infection rate was 0.69%. Univariate Logistic regression analysis showed that gender, age, operation time, antibiotic prophylaxis, internal fixation implantation were risk factors for infections after arthroscopic rotator cuff repair. Multivariate Logistic regression analysis showed male(OR=14.227), age≥65 years(OR=34.313), operation time≥2 h (OR=15.616), without antibiotic prophylaxis(OR=4.891), and internal fixation implantation(OR=5.103) were major risk factors for infection after arthroscopic rotator cuff repair(P<0.05). CONCLUSION Male, age≥65 years, operation time≥2 h, without antibiotic prophylaxis and internal fixation implantation were independent risk factors for infection after arthroscopic rotator cuff repair. Early diagnosis and timely treatment should be carried out to reduce the incidence of infection.

Objective:To observe the effect of theophylline intravenous drip combined with high flow respiratory humidifier on serum pro Calcitonin (PCT) and lactate clearance rate (LCR) in elderly patients with chronic obstructive pulmonary disease (COPD) secondary to type II respiratory failure.Methods:We prospectively selected 120 elderly patients with COPD secondary to type II respiratory failure who were admitted to the Affiliated Hospital of Jining Medical University from March 2020 to March 2022. They were randomly divided into the control group ( n=60) and the observation group ( n=60). The control group was treated with non-invasive positive pressure ventilation combined with theophylline intravenous drip, and the observation group was treated with high flow respiratory humidification therapy apparatus combined with theophylline intravenous drip. The sputum viscosity of the two groups was counted, and the pulmonary function [forced vital capacity (FVC), forced expiratory volume in 1 s (FEV 1), FEV 1/FVC], blood gas analysis, respiratory mechanics, oxygen metabolism, and serum index levels, as well as the difference between acute physiology and chronic health assessment Ⅱ (APACHE Ⅱ) scores after treatment were compared between the two groups. Results:The overall sputum viscosity of the observation group was better than that of the control group ( P<0.05). Before treatment, there was no statistically significant difference in lung function and blood gas analysis indicators between the two groups (all P>0.05); After treatment, the lung function indicators, arterial partial pressure of oxygen (PaO 2), and oxygenation index (PaO 2/FiO 2) of both groups were significantly increased compared to before treatment (all P<0.05), while arterial partial pressure of carbon dioxide (PaCO 2) was significantly decreased compared to before treatment (all P<0.05), and the values of each indicator in the observation group after increasing or decreasing were significantly better than those in the control group (all P<0.05). Before treatment, there was no statistically significant difference in respiratory mechanics and oxygen metabolism indicators between the two groups (all P>0.05); After treatment, the arterial blood oxygen content (CaO 2) in the two groups was significantly higher than that before treatment (all P<0.05), while the oxygen uptake rate (ERO 2) in the two groups and the VO 2 max (VO 2Max), airway peak value, and respiratory resistance in the observation group were significantly lower than those before treatment (all P<0.05), and the values of each index in the observation group after rising or falling were significantly better than those in the control group (all P<0.05). Before treatment, there was no statistically significant difference in serum indicators and APACHE Ⅱ scores between the two groups (all P>0.05); After treatment, LCR and C-reactive protein (CRP) in the observation group were significantly higher than those before treatment ( P<0.05), while the scores of PCT, Interleukin 6 (IL-6), CRP and APACHE Ⅱ were significantly lower than those before treatment (all P<0.05), and the values of each index in the observation group after increase or decrease were significantly better than those in the control group (all P<0.05). Conclusions:Theophylline intravenous drip combined with high flow respiratory humidifier can improve respiratory mechanics, oxygen metabolism, reduce inflammatory reaction, and reduce the impact of disease on life in elderly patients with COPD secondary to type II Respiratory failure.

Objective:To evaluate the application value of left ventricular pressure-strain loop (PSL) in patients with rheumatoid arthritis (RA) by the PSL.Methods:From April 2020 to June 2021, 75 RA patients(case group) and 35 healthy physical examination person(control group) were selected from the Affiliated Hospital of Inner Mongolia Medical University.According to the disease activity scores 28(DAS28) joint disease range of activity score, the patients were divided into low range of activity group (16 cases), medium range of activity group (35 cases) and high range of activity group (24 cases). Echocardiographic examinations were performed on all patients, conventional ultrasound data were collected and the left ventricular PSL technology was used to analyze the myocardial work parameters, including global work index (GWI), global constructive work (GCW), global waste work (GWW) and global work efficiency (GWE). The mean values of myocardial work index (MWI), constructive work (CW), waste work (WW) and work efficiency (WE) were calculated. The differences of myocardial work parameters between the case groups and the control group were compared, and the correlation analysis of myocardial work parameters with global longitudinal strain of left ventricle(LVGLS), left ventricular ejection fraction(LVEF) and DAS28 scores were conducted.Results:①There were no statistically significant differences of clinical data between each case group and the control group (all P>0.05). ②Compared with the control group and low disease activity group, the LVGLS of medium and high disease activity groups decreased obviously (all P<0.05). ③The GWI and GCW of the medium and high disease activity groups were significantly lower than those of the control group (all P<0.05), and there were no statistically significant differences of GWW and GWE between the case groups and the control group (all P>0.05). The mid-segment MWI, apical MWI and CW of the medium and high disease activity case groups, and the mid-segment CW of the medium disease activity case group were lower than those of the control group (all P<0.05). ④In the case group, GWI, GCW and LVEF were significantly and positively correlated ( rs1=0.253, P=0.008; rs2=0.261, P=0.024), and were significantly negatively correlated with LVGLS ( rs1=-0.525, P<0.001; rs2=0.455, P<0.001). There were no significant correlations between myocardial work parameters and DAS28 score (all P>0.05). Conclusions:PSL can early reflect to the impaired cardiac function of RA patients with moderate and high disease activity, and provide a new imaging method for clinical evaluation of the cardiac function of patients.

Objective:To evaluate the cardiac function and systolic dyssynchrony of fetuses exposed to maternal autoimmune antibodies (anti-SSA/Ro60, anti-SSA/Ro52 and anti-SSB/La) by using two-dimensional speckle tracking imaging (2D-STI).Methods:A total of 52 pregnant women with singleton pregnancy in the Affiliated Hospital of Inner Mongolia Medical University from July 2018 to November 2020 were selected. Eighteen fetuses of mothers with autoimmune antibodies were enrolled as autoimmune disease (AD) group and 34 fetuses of healthy mothers without antibodies were included as control group. Maternal baseline characteristics, fetoplacental Doppler parameters, and conventional echocardiographic data of two groups were prospectively collected. The systolic global and regional longitudinal strain of left and right ventricles (LV and RV) and the time to peak strain of regional myocardium were measured using 2D-STI. The differences in time to peak strain between the LV free wall and RV free wall (two-chamber dyssynchrony, 2C-DYS) and between the septum and LV free wall (one-chamber dyssynchrony, 1C-DYS) were also calculated.Results:There were no significant differences between the two groups in conventional systolic and diastolic functional parameters for the LV and RV(all P>0.05). The myocardial deformation parameters and 2C-DYS obtained by 2D-STI showed no statistical differences between two groups(all P>0.05). However, 1C-DYS was significantly more prolonged in the AD group than control group[28.50(13.50, 39.25)ms vs 19.50(8.00, 29.25)ms, P=0.042]. Conclusions:LV systolic mechanical dyssynchrony in fetuses of mothers with autoimmune antibodies suggests in-utero subclinical damage of the cardiac conduction system.

OBJECTIVE: To observe preventive effect of Caprini based thrombosis risk evaluation model on venous thromboembolism (VTE) after total knee replacement (TKA). METHODS: Totally 257 TKA patients were admitted from May 2017 to December 2021 were selected. They were divided into conventional intervention strategies (121 patients in control group) and intervention strategies based on Caprini thrombosis risk evaluation model (136 patients in observation group), based on whether Caprini thrombosis risk evaluation model was introduced in May 2019. In normal gourp, there were 79 males and 42 females aged from 50 to 78 years old with an average of (63.10±11.86) years old;body mass index (BMI) ranged from 19 to 32 with an average of (25.21±4.95) kg/m2;55 patients on the left side and 66 on the right side. In observation group, there were 81 males and 55 females aged from 50 to 78 years old with an average of (64.35±10.54) years old;BMI ranged from 19 to 32 with an average of (24.43±5.18) kg/m²;87 patients on the left side and 49 on the right side. The incidence of VTE, visual analogue scale (VAS), Hospital for Special Surgery (HSS) score, affected limb swelling, mean velocity(Vm), peak velocity (PV), D-dimer (D-D), prothrombin time(PT), and incidence of complications were analyzed and compared. RESULTS: The incidence of VTE in observation group was 1.47%(2/136), and 9.09%(11/121) in control group, and there was statistically difference between two groups (χ²=6.976, P=0.008). At 7 days after operation, VAS, HSS score and the difference in circumference of the affected limb in observation group were significantly better than those in control group, and had statistically differences (P<0.05). Blood flow Vm and PV levels between two groups were significantly increased (P<0.001), and blood flow Vm and PV levels in observation group were significantly higher than those in control group on the 7th day after operation, and had differences (P<0.001). The serum D-D level in observation group was significantly lower than that of in control group on the 7th day after operation, and PT level was significantly higher than that of in control group, and had difference(P<0.05). There was no difference in total incidence of complications between two groups (χ²=4.488, P=0.034). CONCLUSION Intervention strategy based on caprini thrombus risk evluation model could effectively reduce incidence of VTE and complications in TKA patients, improve swelling, hemodynamics and coagulation function of the affected limbs, and contribute to recovery of knee joint function.
