The recombinant human thyroid-stimulating hormone (rhTSH) can be used for differentiated thyroid cancer (DTC) preparation before ¹³¹I therapy, and follow-up. Since its approval by the American Food and Drug Administration (FDA) in 1998, rhTSH has been clinically used in European countries, the United States, and other countries for nearly 30 years. In April 2024, China’s first independently developed rhTSH agent was approved. Based on clinical experience and evidence from domestic and international studies, an expert consensus on the application of rhTSH has been developed following thorough consultations among experts. The consensus offers evidence-based recommendations to guide the appropriate use of rhTSH in clinical practice.

Based on the theory of the five-body constituents from Huangdi Neijing (Yellow Emperor's Internal Classic), the approach and methods of acupuncture for facial aging are explored. Acupuncture for facial aging can be guided by the concept of the five-body constituents, targeting the facial "skin, flesh, vessels, tendons, and bones", and utilizing five different types of needles-facial needles, needle knives, filiform needles, retaining needles, and elongated needles and filiform needles-to maximize their respective advantages in treating facial aging. Facial needles are applied to the "skin" by selecting facial acupoints or local ashi points (at wrinkle or pigmentation sites). Needle knives are used for the "flesh" to perform longitudinal dredging and transverse dissection of the facial muscle layers. Filiform needles target the "vessels" with needling at Renying (ST9) to improve facial complexion. Retaining needles act on the "tendons" with needling from Taiyang (EX-HN5) to Xiaguan (ST7), and Jiache (ST6) to Daying (ST5), using clockwise twisting to generate a retaining needle sensation and lifting to achieve an overall facial lifting effect.

Objective:To develop and validate a risk model of postoperative 3-year all-cause mortality for the elderly patients with hip fracture.Methods:A retrospective study was conducted to analyze the clinical data of 325 elderly patients with hip fracture who had been treated at The Fourth Medical Center, The General Hospital of PLA from January 2020 to December 2021. There were 90 men and 235 women with an age of (80.9±8.9) years, and 191 intertrochanteric fractures and 134 femoral neck fractures. The patients with hip fractures admitted from January 2020 to June 2021 were assigned to a modeling group (244 cases), and those admitted from July to December 2021 to a validation group (81 cases). Recorded were age, gender, fracture type, pre-injury disease, hematological indicators, time from injury to surgery, previous use of anticoagulant drugs, bone density, American Society of Anesthesiologists (ASA) grading, body mass index, and blood transfusion volume in the 2 groups of patients. The data in the modeling group were used to screen the independent risk factors for the postoperative 3-year all-cause mortality in the elderly patients with hip fracture through logistic regression analysis and receiver operating characteristic (ROC) curve analysis and consequently to construct a prediction model. The data in the validation group were used to analyze the predictive performance of the model through the ROC curve, and the fitting degree of the model was evaluated using the Hosmer-Lemeshow goodness-of-fit test.Results:Respectively, 75 cases in the modeling group and 29 cases in the validation group died 3 years after surgery. There was no statistically significant difference in the baseline data between the 2 groups, indicating comparability ( P>0.05). Logistic univariate analysis showed that gender, age, coronary atherosclerotic heart disease before injury, stroke before injury, pulmonary infection before injury, hemoglobin, albumin, high-density lipoprotein, body mass index, time from injury to surgery and ASA grade were related to the mortality of patients 3 years after surgery ( P<0.05). The ROC curve analysis showed that the variables with predictive ability included age, hemoglobin, albumin, body mass index, and time from injury to surgery. Logistic multivariate analysis showed male, age ≥ 83 years, pre-injury stroke, time from injury to surgery ≥ 4.5 days, ASA grade Ⅲ, and ASA grade Ⅳ were significantly related to the postoperative 3-year all-cause mortality in the elderly patients with hip fracture ( P<0.05). In the prediction model based on the above indicators, the area under the ROC curve was 0.792 (95% CI: 0.730 to 0.855, P<0.001), the cutoff value 0.459, sensitivity 56%, and specificity 90.5%, showing a good fit of the model ( χ2=5.818, P=0.668). Conclusions:Male, age ≥ 83 years, pre-injury stroke, time from injury to surgery ≥ 4.5 days, and ASA grades Ⅲ and Ⅳ are risk factors for postoperative 3-year all-cause mortality in the elderly patients with hip fracture. The risk prediction model based on these indicators demonstrates good predictive efficacy.

Objective To analyze the microflora structure and abundance of ileum and colon of SPF male SD rats by high-throughput sequencing technique. MethodsThe ileal and colonic lumen contents of 30 SPF male SD rats were collected, the total bacterial DNA in the contents was extracted and amplified by PCR. The V3-V4 region of bacterial 16S rRNA in the samples was sequenced using Illumina NovaSeq sequencing platform. Then the species structure and abundance of the intestinal flora were analyzed at the phylum and genus level based on validated data. The diversity and differences between ileal and colonic flora were analyzed using the QIIME software (amplicon) analysis tool. The Tax4Fun program was applied to predict the dominant gene enrichment pathways of ileal and colonic flora. ResultsAt the phylum level, the dominant microflora in the ileum of male SD rats were Firmicutes and Actinobacteria, accounting for more than 98%. The dominant colonic microbial community were mainly Firmicutes and Bacteroidetes, accounting for more than 95%. At the genus level, Lactobacillus and Alistipes were the predominant bacteria in the ileum. The colon was dominated by Lactobacillus and Romboutsia. In terms of flora diversity, the alpha diversity of colonic flora including richness index (Chao1 index) and diversity index (Shannon index) were significantly higher than those of ileum (P < 0.01), and the structural variability of the composition of its flora species was smaller than that of ileum; the ileal flora with significant structural variability were mainly of the phylum Firmicutes, Romboutsia, Peptostreptococcaceae, while the colonic flora had significant structural differences in Bacteroidales. In terms of flora function, the ileal flora dominant genes were significantly enriched in lipid-like metabolism, polyketide metabolism, membrane transport, biodegradation and other pathways, while the colonic flora dominant genes were significantly enriched in glycan biosynthesis metabolism, energy metabolism, biosynthesis of cofactor and vitamins and other products, and other pathways. ConclusionThere are significant differences in structure and abundance between the ileal and colonic flora of SPF male SD rats, and the abundance and diversity of colonic flora are higher than those of ileal flora.

Objective To analyze the correlation between quantitative evaluation of high-resolution CT (HRCT) and pulmonary function tests (PFT) in chronic obstructive pulmonary disease (COPD), and evaluate the characteristics of PFT in different CT phenotypes of COPD. Methods 65 patients with COPD underwent CT chest scan and PFT. The dimensions of subsubsegmental apical bronchi of right upper lobes were measured , which included the following parameters:airway wall thickness (T), total airway diameter (D), and pulmonary artery (PA), ratio of airway wall thickness and pulmonary artery (T/PA), thickness diameter ratio (TDR), percentage of wall area (WA%) and percentage of airway luminal area (Ai%). The percentage of total lung area occupied by low attenuation area (LAA%) was measured by lung density software. The relationship between the measurements and PFT parameters were analyzed. Patients were classified into three phenotypes based on the presence of emphysema or bronchial wall thickening evaluated by HRCT. Phenotype A: without or with little emphysema (LAA% < 25%), with or without bronchial wall thickening; Phenotype E: emphysema without bronchial wall thickening (LAA%≥25%, T/PA < 30%); Phenotype M: emphysema with bronchial wall thickening (LAA%≥25%, T/PA≥30%). The characteristics of different CT phenotypes were analyzed. Results LAA% had a good correlation with PFT parameters. PA, T/PA, WA% and Ai% also had correlation with PFT parameters. There was 53 patients of Phenotype A, 12 patients of Phenotype M. PA, T/PA, LAA%and PFT were different in two groups. Conclusions LAA%and airway quantitative measurements in HRCT have certain correlation with PFT parameters. Patients with different CT phenotypes differs in PFT parameters , which can provide reference for clinical diagnosis and treatment.
