The optimal extent of lymph node dissection in N1b papillary thyroid microcarcinoma based on clinicopathological factors and preoperative ultrasonography.

Background: The optimal extent of lymph node (LN) dissection in the management of N1b papillary thyroid microcarcinoma (PTMC) is still under debate in clinical practice, so we aimed to identify the risk factors associated with multilevel lateral lymph node metastasis (LLNM) with regard to the extent of LN dissection.

Methods: The clinical data of 182 N1b PTMC patients between January 2019 and June 2021 at Tianjin Medical University Cancer Institute and Hospital were retrospectively reviewed. The frequency pattern and distribution of LLNM were analyzed for risk factors.

Classification of atrial fibrillation and normal sinus rhythm based on convolutional neural network.

Electrocardiogram (ECG) technology plays a vital role in detecting arrhythmia. Numerous achievements have been marked in ECG-related research. Most methods first pre-process ECG signals, then extract features, and finally classify them.

A Gibbs sampling method to determine biomarkers for asthma.

Purpose: To identify potential biomarkers and to uncover the mechanisms underlying asthma based on Gibbs sampling.

Methods: The molecular functions (MFs) with genes greater than 5 were determined using AnnotationMFGO of BAGS package, and the obtained MFs were then transformed to Markov chain (MC). Gibbs sampling was conducted to obtain a new MC.

A Meta-Analysis of Randomized Controlled Trials of Yiqi Yangyin Huoxue Method in Treating Diabetic Nephropathy.

Objective. The purpose of this systematic review is to evaluate the evidence of Yiqi Yangyin Huoxue Method for diabetic nephropathy. Methods.

[Screening potential DNA barcode regions of genus Papaver].

DNA barcoding is an effective technique in species identification. To determine the candidate sequences which can be used as DNA barcode to identify in Papaver genus, five potential sequences (ITS, matK, psbA-trnH, rbcL, trnL-trnF) were screened. 69 sequences were downloaded from Genbank, including 21 ITS sequences, 10 matK sequences, 8 psbA-trnH sequences, 14 rbcL sequences and 16 trnL-trnF sequences.

Interaction of toxin-1 and T lymphocytes in toxic shock syndrome.

Toxic shock syndrome (TSS) is a potentially fatal illness caused by infection with the bacterium Staphylococcus aureus. TSS toxin-1 (TSST-1) contains a T-cell epitope with specificity for human V-beta-2. Binding of TSST-1 to the human major histocompatibility complex and T cell receptors activates T cells and triggers the secretion of high amounts of inflammatory cytokines, leading to TSS and potentially death.

[Clinical analysis of level V occult metastasis of papillary thyroid carcinoma].

Objective: To analyze the occult level V lymph node (LN) metastases in papillary thyroid carcinoma (PTC) with clinical factors.

Methods: The clinical data of 203 PTC patients with clinical positive neck lymph nodes in level II, III and IV based on preoperative ultrasonography, who underwent therapeutic lateral neck dissection (level II-V) between January 2001 and June 2009 were retrospectively reviewed. There were 60 male and 143 female patients in the study.

[Tracheoesophageal shunt for vocal rehabilitation after laryngectomy].

Objective: To discuss the clinical value of functional tracheoesophageal shunt for vocal rehabilitation after laryngectomy.

Methods: One hundred and twenty seven cases of tracheoesophageal shunt for vocal rehabilitation after laryngectomy in Cancer Hospital of Tianjin Medical University from 1981 to 2006 were analyzed retrospectively.

Results: Among 127 cases, 105 cases got successful phonation and the total success rate of vocal rehabilitation was 82.

[Clinical and pathological analysis of malignant carotid body tumor].

Objective: To summarize the clinical, pathological and prognosis character of malignant carotid body tumor and explore its methods of diagnosis and treatment.

Methods: The data of clinic, pathology, treatment and follow-up of nine patients with malignant carotid body tumor in Tianjin Cancer Hospital from February 1982 to June 2006 were analyzed retrospectively.

Results: Four Male and five female cases were included, their average history was 6.

[Operation strategy for follicular thyroid carcinoma].

Background & Objective: The operation strategies for follicular thyroid carcinoma (FTC), a kind of differentiated thyroid carcinoma, are controversial. This study was to summarize the prognosis of FTC patients after operation, and explore the optimal operation pattern.

Methods: Clinical data of 176 FTC patients who underwent operation at Cancer Hospital of Tianjin Medical University from Jan.
