Objective To explore the method of establishing the value of TSH in the diagnosis of neonatal congenital hypothyroidism in Shantou area.Methods Time resolved fluorescence was conducted to detect the level of heel blood thyrotropin(TSH)in 90 798 neonatal from January 2013 to December 2015 in Shantou area.Percentile method and ROC curve were used to establish the value of TSH screening.Results The frequency of TSH screening in 90 798 cases of neonatal showed normal distribution.The average content of TSH was(2.38-t-2.12)mU/L,ranging 0.0-324.2 mU/L;P90 for 3.46 mU/L;P95 for 4.63 mU/L and P99 for 8.88 mU/L.CH incidence rate in Shantou was 1/2 974;the P99 percentile method TSH diagnostic cut-off value was 8.88 mU/L,and the ROC curve diagnostic cut-off value was 8.49 mU/L.Besides,the recall rate analyzed by chi square test showed no significant difference between the P99 percentile method and ROC curves (χa =0.965,P =0.326).While,a significant difference were found between P99 percentile method and kit(χ2 =10.861,P=0.001),ROC curve and kit(χ2 =5.450,P =0.020).The sensitivity of P99 percentile method and ROC curve method was 100.0 ％.The Youden index of P99 percentile method was 96.9 ％.Conclusion The P99 percentile method is more suitable for clinical neonatal diseases of TSH screening.

Abstract Traditional Chinese medicine (TCM) auscultation has a long history, and with advancements in equipment and analytical methods, the quantitative analysis of auscultation parameters has determined. However, the complexity and diversity of auscultation, along with variations in devices, analytical methods, and applications, bring challenges to its standardization and deeper application. This review presents the advancements in auscultation equipment and systems, auscultation characteristic parameters, and their application in the diagnosis of pulmonary diseases and syndromes over the past 10 years, while also exploring the progress and challenges of current digital research of auscultation. This review also proposes the establishment of standardized protocols for the collection and analysis of auscultation data, the incorporation of advanced artificial intelligence (AI) auscultation analysis methods, and an exploration of the diagnostic utility of auscultatory features in pulmonary diseases and syndromes, so as to provide more precise decision support for intelligent diagnosis of pulmonary diseases and syndromes

Objective To evaluate the combination use of thyroid fine needle aspiration biopsy (FNAB)and V-Raf murine sarcoma viral oncogene homolog B1 (BRAF) V600E gene mutation testing in differentiating benign from malignant thyroid nodules.Methods A total of 64 patients with pathologically-proved thyroid nodules were included in this study.The clinical data,including preoperative ultrasound-guided thyroid FNAB and BRAF V600E gene mutation detection,were retrospectively analyzed.Taking postoperative histopathological results as diagnostic gold standard for the thyroid nodule,the diagnostic values of simple FNAB,simple BRAF V600E gene mutation testing,and combination use of FNAB and BRAF V600E gene mutation detection were separately assessed.Results In the 62 patients a total of 64 nodules were detected (2 patients having bilateral nodules) and treated with surgery.Of the 64 nodules,BRAF V600E mutation was detected in 44 nodules,and 43 nodules were proved to be thyroid papillary carcinoma by postoperative pathological examination.Among the 44 nodules showing BRAF V600E mutation,FNAB made malignant diagnosis in 28,benign diagnosis in 6,and uncertain diagnosis in 10.Of the 20 nodules showing no BRAF V600E mutation,FNAB made malignant diagnosis in 5,benign diagnosis in 3,and uncertain diagnosis in 12.The postoperative pathological examination confirmed that 14 lesions were thyroid papillary carcinoma,4lesions were nodular goiter,one lesion was subacute thyroiditis,and one lesion was thyroid adenoma.Among the 57 thyroid papillary carcinomas,BRAF V600E mutation was detected in 43,with the mutation rate being 75.4％.Compared with the gold standard based on pathological diagnosis,the sensitivity,specificity,positive predictive value,negative predictive value,correct diagnosis rate of FNAB for judging benign or malignant thyroid nodules were 78.9％,85.7％,97.8％,33.3％ and 79.7％ respectively,which of BRAF V600E gene mutation detection for judging benign or malignant thyroid nodules were 75.4％,85.7％,97.7％,30.0％ and 76.6％ respectively,and which of FNAB plus BRAF V600E gene mutation detection for judging benign or malignant thyroid nodules were 94.7％,71.4％,96.4％,62.5％ and 92.2％ respectively.By using McNemar paired data x2 test to compare FNAB with combination use of FNAB plus BRAF V600E gene mutation detection in diagnosing thyroid nodules,the results indicated that statistically significant deference in differentiating benign from malignant thyroid nodules existed between the two methods (P＜0.001).Conclusion For the qualitative diagnosis of thyroid nodules which nature cannot be determined by simple FNAB,FNAB combined with BRAF V600E gene mutation detection can improve the diagnostic accuracy for benign and malignant thyroid nodules.

BACKGROUND: The extramedulary fixation system including dynamic hip screw (DHS) is commonly used in treatment of Intertrochanteric fracture. However, in patients with unstable intertrochanteric fracture, extramedulary fixation system often leads to the failure of fracture fixation. Intramedulary fixation system including both proximal femoral nail antirotation (PFNA) and InterTan nail has been widely used in the treatment of unstable intertrochanteric fractures. OBJECTIVE:To compare the therapeutic effects of extramedulary fixation system containing DHS, PFNA and InterTan nail in the treatment of intertrochanteric fracture. METHODS:Literatures were searched in Wanfang, PubMed, Embase, Medline, the Cochrane library to screen literatures published from January 1990 to November 2014. Relevant studies addressing extramedulary fixation system containing DHS, PFNA and InterTan nail were screened. RESULTS AND CONCLUSION: 346 articles were screened, and 13 of them were in accordance with the inclusion criteria. 1 271 patients with different types of intertrochanteric fracture were assessed in this study. Compared to DHS group, patients treated with PFNA and InterTan nail had shorter operation time and less blood loss. No significant difference in rehabilitation time and Harris score was detected among three kinds of fixation methods. Additionaly, PFNA and InterTan nail had a similar effect. These findings verify that compared with DHS, PFNA and InterTan nail can optimize the surgery, but cannot elevate postoperative outcomes.

Ten to twenty ?l of 20-50% horseradish peroxidase (HRP) in normal saline solution was injected into the myocardium of the anterior wall of left and right ventricles in 11 rabbits. The areas containing sino-atria as well as atrio-ventricular nodes and the dorsal wall of the atria were removed separately. Frozen or cryostate sections of these tissues 25-40?m thick, were incubated according to the HRP (tetramethylbenzidine "TMB" method)-AChE combined method. The blue granules produced by the HRP with TMB were observed in the perikarya of a few AChE intensely positive ganglion cells which were located in the epicardium of the dorsal wall of the atria. This indicated the processes of the HRP-AChE double labeled cells distributed to the myocardium of the anterior wall of the ventriculum. It is generally believed that the nerve cells of strong AChE activity can be referred as cholinergic neurons. For this reason, the present study may give further identification to assert the parasympathetic innervation of the ventricular myocardium. The parasympathetic postganglionic neurons innervated the anterior wall of left and right ventriculi are situated primarily in the epicardium of the posterior wall of the atria.
