Objective To analyze the dynamic changes in serum adiponectin (APN) levels after acute myocardial infarction (AMI) and its relationship with heart failure (HF) and major adverse cardiovascular events (MACE). Methods A total of 124 AMI patients who underwent percutaneous coronary intervention (PCI) in our hospital from January 2021 to December 2023 were enrolled as AMI group. Additionally, 30 patients with non-AMI coronary artery disease and 30 healthy individuals were included in non-AMI coronary artery disease group and healthy group, respectively. General information such as age, gender, smoking, alcohol consumption, hypertension, diabetes, and blood lipids were recorded for all subjects. Serum APN levels were measured using the enzyme-linked immunosorbent assay (ELISA) method; plasma brain natriuretic peptide (BNP) levels were determined by immunofluorescence; and left ventricular ejection fraction (LVEF) was assessed using echocardiography. Changes in serum APN levels and its relationship with BNP, LVEF, and MACE were recorded during a one-year follow-up period. Results AMI patients had lower serum APN levels than those in the non-AMI coronary artery disease group and the healthy group, while levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C); Lipoprotein-associated phospholipase A2 (Lp-PLA2), and the proportions of smokers and diabetics were higher(P < 0.05). A one-year follow-up of AMI patients revealed an upward trend in serum APN and BNP levels and a downward trend in LVEF levels at one week, one month, three months, six months, and one year postoperatively (P < 0.05). APN and BNP levels peaked one month after PCI, while LVEF reached its lowest level at the same time point. However, there were no statistically significant changes in these indicators in the subsequent 11 months (P>0.05). The incidence of MACE in AMI patients at one, three, six, and twelve months postoperatively was 2.8%, 3.2%, 4.6%, and 8.8%, respectively. Both preoperative and one-month postoperative serum APN levels had high predictive value for the occurrence of HF and MACE within one year in AMI patients, and the area under the curve for predicting HF and MACE one month postoperatively was larger than that preoperatively (P < 0.05). Conclusion Serum APN levels in AMI patients show an upward trend after PCI, peaking one month postoperatively. At this time point, serum APN levels have the highest predictive value for the occurrence of HF and MACE.

Objective To analyze the efficacy of drug-coated balloon in the treatment of hetero-geneous in-stent restenosis.Methods A total of 118 patients who received treatment and diagnosed with heterogeneous in-stent restenosis were selected as study objects,and were divided into two groups using a random table method.The experimental group(n=59)received drug-coated balloon thera-py,and the control group(n=59)received drug-eluting stent therapy.The therapeutic effects of the two different treatment methods on heterogeneous in-stent restenosis were compared.Results There was no significant difference in the incidence of in-stent restenosis in the right coronary artery,cir-cumflex artery,and anterior descending artery between the two groups(P＞0.05).There was no sig-nificant difference between the two groups in the preoperative reference vessel diameter,lesion length,lumen stenosis degree,and localized restenosis(P＞0.05).The postoperative residual ste-nosis rate in the experimental group was significantly higher than that in the control group(P＜0.05).There was no significant difference between the two groups in the preoperative lumen area,neointimal load,stent inner area,neointimal area,incidence of neoatherosclerosis and thrombus(P＞0.05).Operative lumen area of the experimental group was smaller than that of the control group(P＜0.05).No target vessel reconstruction,stent thrombosis,nonfatal myocardial infarction,or cardiac death occurred in two groups during 12 months of follow-up.Conclusion Drug-coated balloons are effective and safe in the treatment of heterogeneous in-stent restenosis,and can obtain similar effects to drug-eluting stents.

Head and neck squamous cell carcinoma (HNSCC), as the most common type (>90%) of head and neck cancer, includes various epithelial malignancies that arise in the nasal cavity, oral cavity, pharynx, and larynx. In 2020, approximately 878 ‍ 000 new cases and 444 000 deaths linked to HNSCC occurred worldwide (Sung et al., 2021). Due to the associated frequent recurrence and metastasis, HNSCC patients have poor prognosis with a five-year survival rate of 40%-50% (Jou and Hess, 2017). Therefore, novel prognostic biomarkers need to be developed to identify high-risk HNSCC patients and improve their disease outcomes.

Objective: To establish reference intervals (RIs) of thyroid hormone based on data from healthy subjects in laboratory information system (LIS) by indirect methods. Methods: Data were selected from the physical examination center in LIS of the First Hospital of Jilin University from May 2014 to December 2018. The normal distribution of the original data was checked by the Kolmogorov-Smirnov test. Skewed data were transformed into normal distribution using BOX-COX techniques, and outliers were identified by the Turkey method. The continuous percentile curve was established by coefficient of skewness-median-coefficient of variation(LMS) methods. Cut-off value of age was determined by decision trees, and the differences between groups were verified by Z-tests. P_2.5 and P_97.5 in the RIs were analyzed by non-parametric methods. Results: A total of 45 742 subjects were included in the study. There were no differences in the RI for thyroid stimulating hormone (TSH) among age groups or between men and women (Z*), and the RI was 0.60-4.41mIU/L (20-79 years old). However, the levels of free triiodothyronine(FT₃) decreased with age in males and females under 35-year-old. The RIs for FT₃ were 4.47-6.44pmol/L (20-44 years old), 4.19-6.21pmol/L (45-64 years old) and 3.90-5.85pmol/L (65-79 years old) in males, and 4.04-6.13pmol/L (20-34 years old) and 3.87-5.76pmol/L (35-79 years old) in females, respectively. The levels of free thyroxine(FT₄) in men were higher than those in women from 20 to 49 years old, and no gender and age differences could be viewed in subjects after 50 years old (Z*). The RIs for FT₄ were 13.69-21.76pmol/L (male, 20-49 years old), 12.99-20.83pmol/L (female, 20-49 years old) and 12.98-21.21pmol/L (50~79 years old). Conclusion Establishment of RIs of thyroid hormone based on the data from LIS is simple and reliable, which is suitable for clinical laboratory application.

Objective To verify the Standards Reference Intervals for Common Clinical Biochemistry Tests and to determine if the standards are suitable for Jilin area.Methods Healthy Han reference individuals at 20-＜80years old were selected as reference individuals and there were more than 30cases for each sex in every 10years old group.The blood samples were detected by HITACHI 7600-210automatic biochemical analyzer.Differences between sex and age for 8clinical chemistry parameters were evaluated and distribution in range of reference individuals were analyzed.Results The levels of albumin among different age periods of male were shown a downward trend.The levels of AST in male, ALP and GGT in female were shown a upward trend with the growth of age.The levels of ALT in female, ALT and GGT in male were shown an upward trend at 20-＜60years old, while a downward trend was shown at 60-＜80years old.Nevertheless, the average levels of all the groups were within the recommended reference intervals.Over 94％of verification for eight common clinical biochemistry tests (6subgroups for male and 6subgroups for female) were in the reference range and all passed validation.Conclusion Standards Reference Intervals for Common Clinical Biochemistry Tests are applicable to Chinese Han population in Jilin area.

Objective: To discuss the clinical application and effects of domestic external fixator in the treatment of patients with malformations of limbs. Methods: A total of 7 289 patients with malformation of limbs who had been operated in Qin Sihe orthopedic surgery team from January 1989 to June 2016 were retrospective analyzed. The patients were treated with domestic external fixator, including 4 033 males and 3 256 females, aging from 2 to 82 years with a mean age of 23.4 years. There were 2 732 patients using Ilizarov external fixator, 4 713 patients using hybrid external fixator, 57 patients using monobrachial external fixator, 232 patients using Ilizarov external fixator and hybrid external fixator. The Ilizarov, hybrid and monobrachial external fixator were used in 67, 65 and 0 patients on the upper limbs and in 2 665, 4 616 and 57 patients on the lower limbs. There were 3 028 patients operated on the left limbs, 3 260 patients operated on the right limbs and 1 001 patients operated on the bilateral limbs. The top three types of diseases were sequelae of poliomyelitis, cerebral palsy and post-traumatic stress disorder peromely. Deformity types inclued talipes equinovarus, knee flexion deformity, cavus foot and so on. Results: All the patients were followed up for a period of 2.5 months to 22.4 years, with an average follow-up time of 5.4 years. All of the external fixators were used for single once, and there was no substitute for external fixator quality problem. All the patients were completed surgery goal until removing external fixation except 1 patient gave up treatment and 1 removed the fixator because of metal allergy. The common complications included wire or pin infection and joint movement limitation and so on. Conclusions The domestic external fixator developed and produced based on the characteristics of Chinese limb deformity disability. The domestic external fixator can be used to treat kinds of limb deformities with the advantages of practical, economical, adjustable, universal and portable. The domestic external fixator could meet the clinical demand for fixation of the osteotomy end of the limbs, the correction of the deformity, the repair of the defects and the limb lengthening.
