Objective To explore the medication rules of Professor Li Huilin in treating Hashimoto's thyroiditis(HT)complicated with hypothyroidism using data mining techniques based on the R language.Methods Prescription data of the patients with HT complicated with hypothyroidism treated by Professor Li Huilin in outpatient clinics from March 2023 to March 2024 were collected.A database was established using Microsoft Excel 2021,and R language was employed to analyze the frequency,efficacy,properties and flavors,and meridian tropism of the medicinals from Chinese herbal prescriptions.Additionally,correlation analysis,association rule analysis,and cluster analysis were performed on the medicines from Chinese herbal prescriptions.Results A total of 57 Chinese herbal prescriptions involving 125 medicinals with 782 medication frequencies were included.The top 10 frequently-used medicinals were Glycyrrhizae Radix et Rhizoma Praeparata cum Melle(Zhigancao),Angelicae Sinensis Radix(Danggui),Atractylodis Macrocephalae Rhizoma(Baizhu),Astragali Radix(Huangqi),Bupleuri Radix(Chaihu),Cinnamomi Ramulus(Guizhi),Leonuri Herba(Yimucao),Paeoniae Radix Alba(Baishao),Poria(Fuling),and Fici Simplicissimae Radix(Wuzhimaotao).Most of the medicinals had therapeutic action of tonifying deficiency.The analysis of properties and flavors showed that the majority of medicinals were mild or warm in nature,and sweet in flavor.The top three meridians having the tropism of medicinals were the liver,lung,and spleen meridians.Correlation analysis identified five strongly-correlated herbal combinations.Association rule mining revealed a core herbal combination consisting of seven medicinals of Zhigancao,Huangqi,Danggui,Chaihu,Codonopsis Radix(Dangshen),Baizhu,and Cyperi Rhizoma(Xiangfu).Cluster analysis of medicinals with a frequency of≥5 yielded five groups of herbal combination.Conclusion For the treatment of HT complicated with hypothyroidism,Professor Li Huilin follows the principle of addressing the root cause of the disease,and focuses on strengthening the spleen and replenishing qi.Moreover,attention is given to soothing the liver and regulating qi,harmonizing qi and blood simultaneously,and treating symptoms and root cause simultaneously.

Objective:To investigate the prospective association between lifestyle and the risk for all-cause mortality in middle-aged and elderly residents in China.Methods:The data from China Health and Retirement Longitudinal Study were used. Baseline information about the lifestyle were collected through questionnaire survey and physical measurements, and the mortality data were obtained through surveys conducted at 2-3 year intervals. A total of 5 436 study participants were included. A comprehensive lifestyle including smoking, alcohol consumption, sleep, BMI and physical activity was constructed, and a multivariate-adjusted Cox proportional hazards regression model was used to estimate the association between lifestyle and the risk for all-cause mortality.Results:During the follow-up of average 8.2 years, 695 deaths were recorded. The comprehensive lifestyle score was linearly associated with the risk for all-cause mortality. Compared with the study participants with comprehensive lifestyle score of 0-1, those with score of 2-5 all had lower risk for all-cause mortality, with HRs of 0.78 (95% CI: 0.62-0.98), 0.56 (95% CI: 0.44-0.72), 0.36 (95% CI:0.27-0.48), and 0.33 (95% CI: 0.21-0.52), respectively. The results of Cox proportional hazards regression model analysis of single lifestyle showed that compared with those with unhealthy lifestyles, the HRs of all-cause mortality for study participants who never smoked, had moderate alcohol consumption, had appropriate night sleep, maintained healthy body weight and kept active physical activity were 0.70 (95% CI: 0.57-0.84), 0.76 (95% CI: 0.64-0.90), 0.79 (95% CI: 0.67-0.94), 0.73 (95% CI: 0.62-0.87), and 0.68 (95% CI: 0.58-0.80), respectively. Conclusions:Keeping healthy lifestyles can significantly reduce the risk for all-cause mortality in middle-aged and elderly residents China. The higher the healthy lifestyle level, the lower the risk for all-cause mortality.

BACKGROUND:With the continuous improvement of artificial biological materials and surgical techniques,total knee arthroplasty has become the preferred way to improve the quality of life of patients with knee osteoarthritis. However,patients with knee osteoarthritis have severe pain after knee arthroplasty,and there is no good treatment at present. Electroacupuncture therapy is a low-cost option for pain relief and has wide application prospects in combination with preemptive analgesia.OBJECTIVE:To investigate the effect of opposing needling acupuncture with preemptive analgesia on postoperative analgesia after initial unilateral total knee arthroplasty in patients with knee osteoarthritis.METHODS:Using a randomized controlled design,120 participants were selected from Shanghai Guanghua Hospital of Integrative Medicine. All of them received the initial unilateral total knee arthroplasty. The patients were divided into three groups by using the statistical software SPSS 25:pre-electroacupuncture group,post-electroacupuncture group,and sham group,with 40 patients in each group. In pre-electroacupuncture group,opposing needling acupuncture was performed 1 day before operation,30 minutes before anesthesia induction,and 1-3 days after operation. In post-electroacupuncture group,opposing needling acupuncture was performed with the same acupoints and parameters 1-3 days after operation,thus the sham electroacupuncture was performed 1 day before operation and 30 minutes before anesthesia induction. The sham group was treated with the same acupuncture point parameters with five times of sham electroacupuncture. The improvement of numerical rating scale after operation,the consumption of remifentanil and propofol used during operation,the time when patient first used the patient-controlled analgesia,the number of postoperative nausea and vomiting,the increase rate of thigh circumference,and the success rate of blind method were compared among the three groups.RESULTS AND CONCLUSION:(1) Compared with the pre-electroacupuncture group,the improvement of numerical rating scale at rest between post-electroacupuncture group and sham group on day 4 after operation was significantly reduced;the improvement of numerical rating scale at rest in sham group on day 7 after operation was significantly reduced (P<0.05). (2) Compared with the pre-electroacupuncture group,the improvement of numerical rating scale score between post-electroacupuncture group and sham group on day 4 after operation was significantly reduced (P<0.05),and the improvement of numerical rating scale with movement on day 7 after operation was not significant among the three groups (P>0.05). (3) Compared with the pre-electroacupuncture group,the remifentanil consumption was significantly increased in post-electroacupuncture group and sham group (P<0.05). (4) Compared with the pre-electroacupuncture group,the first time used the patient-controlled analgesia pump was significantly shortened in post-electroacupuncture group and sham group (P<0.05). (5) Compared with the pre-electroacupuncture group,the number of postoperative nausea was increased in post-electroacupuncture group and sham group (P<0.05). (6) Compared with the pre-electroacupuncture group,the increase rate of thigh circumference in post-electroacupuncture group and sham group was significantly increased on day 3 and day 7 after operation (P<0.05). Compared with the post-electroacupuncture group,the increase rate of thigh circumference in sham group was significantly increased on day 3 and day 7 after operation (P<0.05). (7) There was no significant difference in the success rate of blind method among the three groups (P>0.05). (8) The artificial knee prosthesis has good biocompatibility. To conclude,opposing needling acupuncture with preemptive analgesia can relieve acute pain after total knee arthroplasty,reduce the consumption of intraoperative anesthesia,prolong the time of postoperative analgesia,alleviate postoperative adverse reactions,and reduce the increase rate of thigh circumference.

Objective To explore the correlation between serum glycosylated hemoglobin(HbA1c),lym-phocyte activation gene-3(LAG-3)and thyroid nodules in patients with type 2 diabetes mellitus(T2DM).Methods A total of 120 T2DM patients with thyroid nodules admitted to the Third Hospital of Hebei Medi-cal University from July 2021 to July 2022 were included as the study group,and 100 simple T2DM patients(without thyroid nodules)were included as the control group during the same period.According to the patho-logical examination results of thyroid nodules,the study group was grouped into a benign nodule group(85 ca-ses)and a malignant nodule group(35 cases).Enzyme linked immunosorbent assay was applied to detect the serum LAG-3 level of all study subjects.Fully automated glycated hemoglobin analyzer was applied to detect HbA1c level in all study subjects.Spearman method was applied to analyze the correlation between serum HbA1c,LAG-3,and thyroid imaging report and data system(TI-RADS)scores in patients with T2DM and thyroid nodules.Multivariate Logistic regression was applied to analyze the influencing factors of T2DM with thyroid nodules.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of HbA1c and LAG-3 levels in T2DM with thyroid nodules.Results Compared with the control group,the level of HbA1c in the study group was obviously higher(P<0.05),while the level of LAG-3 was obviously lower(P<0.05).Compared with the benign nodule group,the serum LAG-3 level in the malignant nodule group was obviously lower(P<0.05),while the level of LAG-3 was obviously lower(P<0.05).Spearman analysis showed a positive correlation between HbA1c level and TI-RADS score in T2DM patients with thyroid nod-ules(r=0.378,P<0.001),while the serum LAG-3 level was negatively correlated with TI-RADS score(r=-0.472,P<0.001).The results of multivariate Logistic regression analysis showed that HbA1c was a risk factor for the occurrence of thyroid nodules in T2DM patients(P<0.05),and LAG-3 was a protective factor for the occurrence of thyroid nodules in T2DM patients(P<0.05).The combination of HbA1c and LAG-3 in the diagnosis of T2DM with thyroid nodules was superior to their individual diagnosis(Zcombination-HbA1c=2.542,P=0.011;Zcombination-LAG-3=3.098,P=0.002).Conclusion Patients with T2DM combined with thyroid nodules have obviously lower serum LAG-3 level and higher HbA1c level,and the two are related to the malignancy of thyroid nodules.

Objective To understand the changing distribution and antimicrobial resistance profiles of Proteus,Morganella and Providencia in hospitals across China from January 1,2015 to December 31,2021 in the CHINET Antimicrobial Resistance Surveillance Program.Methods Antimicrobial susceptibility testing was carried out following the unified CHINET protocol.The results were interpreted in accordance with the breakpoints in the 2021 Clinical & Laboratory Standards Institute(CLSI)M100(31 st Edition).Results A total of 32 433 Enterobacterales strains were isolated during the 7-year period,including 24 160 strains of Proteus,6 704 strains of Morganella,and 1 569 strains of Providencia.The overall number of these Enterobacterales isolates increased significantly over the 7-year period.The top 3 specimen source of these strains were urine,lower respiratory tract specimens,and wound secretions.Proteus,Morganella,and Providencia isolates showed lower resistance rates to amikacin,meropenem,cefoxitin,cefepime,cefoperazone-sulbactam,and piperacillin-tazobactam.For most of the antibiotics tested,less than 10％of the Proteus and Morganella strains were resistant,while less than 20％of the Providencia strains were resistant.The prevalence of carbapenem-resistant Enterobacterales(CRE)was 1.4％in Proteus isolates,1.9％in Morganella isolates,and 15.6％in Providencia isolates.Conclusions The overall number of clinical isolates of Proteus,Morganella and Providencia increased significantly in the 7-year period from 2015 to 2021.The prevalence of CRE strains also increased.More attention should be paid to antimicrobial resistance surveillance and rational antibiotic use so as to prevent the emergence and increase of antimicrobial resistance.
