Objective: To assess the effect of transarterial embolization (TAE) for adhesive capsulitis (AC) by evaluating clinical outcomes and changes in inflammation using magnetic resonance imaging (MRI). Materials and Methods: Patients who had undergone TAE between August 2020 and August 2023 for AC refractory to conservative treatments without any invasive procedures for more than 3 months, and had undergone baseline and 3-month post-AC follow-up contrast-enhanced MRI evaluations, were included. A suspension mixture of 500 mg imipenem/cilastatin in 10 mL of iodinated contrast agent was used for TAE. MRI results were analyzed to assess periarticular capsule/ligament inflammation. Clinical assessments included pain scores using the numeric rating scale (NRS) and functional scores using the quick disabilities of the arm, shoulder, and hand (Quick DASH) questionnaire. Results: Twenty-five patients (female:male, 14:11; age, 54.9 ± 7.1 years) were included. Significant reductions in average NRS pain scores as well as improvements in Quick DASH scores and range of motion, including anterior flexion and abduction, were observed at 1, 3, and 6 months after TAE (all P < 0.001). MRI analyses revealed that TAE significantly decreased the grades of axillary recess capsule enhancement, rotator interval (RI) capsule T2 signal intensity, and RI capsule enhancement (all P ≤ 0.004). Conclusion TAE may be an effective and safe therapeutic approach for AC refractory to conservative treatments, alleviating pain and supporting functional recovery. The observed MRI findings suggest that the effectiveness of TAE for AC may be attributed to the reduction of inflammation and the elimination of angiogenesis.

The analysis of ammonia nitrogen in real water samples is challenging due to matrix interferences and difficulties for rapid on-site analysis.On the basis of the standard method,i.e.water quality-determination of ammonia nitrogen-salicylic acid spectrophotometry(HJ 536-2009),a simple device for online detecting ammonia nitrogen was developed using a sequential injection analysis(SIA)system in this work.The ammonia nitrogen transformation system,color reaction system,and detection system were built in compatible with the SIA system,respectively.In particular,the detection system was assembled by employing light-emitting diode as the light source,photodiode as the detector,and polyvinylchloride tube as the cuvette,thus significantly reducing the volume,energy consumption and fabricating cost of the detection system.As a result,the accurate analysis of ammonia nitrogen in complex water samples was achieved.A quantitative detection of ammonia nitrogen in water sample was obtained in 12 min,along with linear range extending to 1000 μmol/L,precisions(Relative standard deviation,RSD)of 4.3%(C=10 μmol/L,n=7)and 4.2%(C=500 μmol/L,n=7),and limit of detection(LOD)of 0.65 μmol/L(S/N=3,n=7).The results of interfering experiments showed that the detection of ammonia nitrogen by the developed device was not interfered by the common coexisting ions and components,therefore the environmental water could be directly analyzed,such as reservoir water,domestic sewage,sea water and leachate of waste landfill.The analytical results were consistent with those obtained by the environmental protection standard method(Water quality determination of ammonia nitrogen-salicylic acid spectrophotometry,HJ 536-2009).In addition,the spiking recoveries were in the range of 92.3%-98.1%,further confirming the accuracy and practicality of the developed device.

Objective To explore the clinical efficacy of high hip center technique total hip arthroplasty(THA)for CroweⅡ and Ⅲ developmental dysplasia of hip(DDH)and severe hip osteoarthritis(HOA).Methods From January 2018 to Jan-uary 2020,74 patients with Crowe type Ⅱ and Ⅲ DDH and severe HOA were admitted,and 37 cases of anatomical hip center reconstruction were taken as control group,including 7 males and 30 females,aged from 42 to 65 years old with an average of(58.40±4.98)years old,body mass index(BMI)ranged from 18 to 29 kg·m-2 with an average of(23.02±2.21)kg·m-2.Thirty-seven routine high hip center technical reconstruction were performed as study group,including 5 males and 32 females,aged from 41 to 65 years old with an average of(57.31±5.42)years old,BMI ranged from 18 to 29 kg·m-2 with an average of(23.14±2.07)kg·m-2.The patients presented with hip pain,limited function and range of motion,and gait instability before surgery.All patients underwent THA,the control group underwent intraoperative anatomical hip center reconstruction,and the study group underwent intraoperative high hip joint reconstruction.The perioperative indicators of the two groups were com-pared.The hip joint function,balance function and gait of the patients were evaluated before surgery,3 months,6 months,and 12 months after surgery.The length difference of both lower limbs,horizontal distance of rotation center,vertical distance of ro-tation center and femoral eccentricity were measured before operation and 1 year after operation.The incidence of complica-tions in the two groups during the operation and postoperative follow-up was counted.Results The operation time of the study group was shorter than that of the control group,and the intraoperative blood loss was less than that of the control group(P＜0.05).After 12-months follow-up,1 was lost to followvup in study group and 2 were lost to follow-up in control group.The Har-ris scores and Berg balance scale(BBS),pace,stride frequency and single step length in the study group were higher than those in the control group at 3 months and 6 months after operation(P＜0.05);there was no statistically significant difference between the two groups in the indexes 12 months after operation(P＞0.05).The vertical distance of the center of rotation of the study group was greater than that of the control group 12 months after operation(P＜0.05),and there was no significant difference in the length difference of the lower limbs,the horizontal distance of the center of rotation,and the femoral eccentricity between two groups(P＞0.05).There were no complications in either group.Conclusion The long-term effects of TH A in patients with DDH and severe HO A were similar between the two central hip reconstruction methods,and the safety was good,and the high hip central reconstruction technique could shorten the operation time and reduce the amount of intraoperative blood loss.At the same time,it has certain advantages in early recovery of hip joint function,balance function and walking function of patients.

Objective:To understand the epidemiological characteristics and incidence trend of severe fever with thrombocytopenia syndrome (SFTS) in China.Methods:The incidence data of SFTS in China from 2018 to 2021 were collected from Chinese Disease Prevention and Control Information System for a statistical and descriptive epidemiological analysis by using software such as Excel 2016, Joinpoint 5.0.2, SPSS 26.0, and GraphPad Prism 8.0, especially, the SFTS cases reported monthly by key provinces were analyzed.Results:From 2018 to 2021, a total of 8 835 SFTS cases were reported in 25 provinces and the annual incidence showed an upward trend. The distribution of SFTS cases showed clustering, but the cases were mainly sporadic ones. The cases began to increase in March, mainly occurred during April to October (96.79%,8 551/8 835), and peaked during May to July. The cases were mainly distributed in middle-aged and old farmers, and slight more cases were women. The average case fatality rate was 5.38%, which varied greatly with areas. The case fatality rate tended to increase with age.Conclusion:From 2018 to 2021, the epidemiological characteristics of SFTS in China remained stable, but the number of reported cases gradually increased and the distribution showed an expanding trend, to which close attention should be paid.

Objective To analyze the incidence of major adverse cardiovascular events(MACE)in 45 patients who unexpectedly interrupted dual antiplatelet therapy(DAPT)within one month after percutaneous coronary intervention(PCI).Methods A total of 4 876 patients who successfully underwent PCI and implanted one or more stents(excluding acute ST segment elevation myocardial infarction,drug coated balloon or non-drug coated ballooon only,and oral anticoagulants)between January 1,2017 and December 31,2022 were selected as the study subjects.A total of 45 patients with unexpected interruption of DAPT within one month after PCI were analyzed,and their clinical outcomes were followed up.Results Among the 45 patients,there were 29 males and 16 females,aged 48-80(61.7+15.3)years.The reasons for interrupting DAPT include:35 cases of bleeding;3 cases of malignant tumor surgery(including 2 bleeding patients);5 cases of trauma;2 cases of hematological diseases;2 cases of self-interruption of DAPT.6 patients who received low-molecular-weight heparin replacement therapy during the discontinuation period did not experience stent thrombosis or other MACE.Among the 39 patients without antithrombotic replacement therapy,5 developed stent thrombosis and acute myocardial infarction(5/45,11.1％).Except for 1 patient who voluntarily stopped DAPT 2 weeks after PCI,the remaining 4 cases were those who with concurrent bleeding within 2 weeks after PCI.DAPT was stopped for more than 10 days,and stent thrombosis occurred on the 10th,11th,11th,and 13th days after DAPT was stopped.Among the 4 patients,2 patients developed acute left heart failure and 1 patient died.Another case died due to brainstem hemorrhage.Conclusions Premature interruption of DAPT after PCI has a high potential risk.Patients who stop taking medication earlier,for a longer duration,and without replacement therapy have a higher risk.
