In recently years,the incidence rate of obesity - related glomerulopathy(ORG)is increasing. Adi-pose tissue as a new endocrine organ releases inflammatory factors which can lead to glomerular artery endothelial damage,mesangial expansion and extracellular matrix accumulation and podocyte lesion,etc. Studies have confirmed that the chronic inflammation may play a key role in the pathogenesis of ORG. Now,the molecular mechanisms of chro-nic inflammation and its effect in the development of ORG were summarized.

Objective To analyze the expression of TBX1 gene in kidney tissues in patients with clear cell renal cell carcinoma(ccRCC)and in?vestigate its molecular genetics mechanism during the tumor development. Methods Real?time quantitative polymerase chain reaction(qRT?PCR)was used to detect the expression of TBX1 mRNA in 12 cases of clear cell renal cell carcinoma tissues and the corresponding normal kidney tissues adjacent to carcinoma .The protein expression of TBX1 was assayed by Western blot in both groups. Results Both TBX1 mRNA level and the protein level were significantly up?regulated in ccRCC tissues compare to those in normal kidney tissues adjacent to carcinoma(all P<0.05). Conclusion Over?expression of TBX1 gene might be a potentially pathogenic mechanism of ccRCC.

Objective:To study the origin traceability of anemarrhenae rhizoma from Bozhou and Hebei based on multi-element fingerprints technology , and establish a discrimination model .Methods:The contents of 48 elements were determined by using induc-tively coupled plasma mass spectrometry ( ICP-MS) for 44 samples of anemarrhenae rhizome from Bozhou and Hebei province .Princi-pal component analysis ( PCA) and orthogonal partial least squares discrimination analysis ( OPLS-DA) were applied in the data analy-sis to screen out the significant elements .And then Fisher linear discrimination analysis was used to determine the origin of anemarrhe-nae rhizoma and the discrimination models were developed .Results:Two discrimination models were developed by the discrimination a-nalysis of the whole model method with nine significant elements identified by PCA and OPLS -DA, and 100％correct classification and 95.5％cross validation were achieved by the models .Conclusion: It is a promising approach to classify the geographical origin of anemarrhenae rhizome based on multi-element fingerprints analysis combined with multivariate statistical analysis .The discrimination models are good enough to be applied in the origin traceability of anemarrhenae rhizome.

Objective To explore the clinical value of nodal metastatic characteristics in predicting the distant metastasis of papillary thyroid carcinoma (PTC).Methods A total of 1 408 PTC patients who met the inclusion criteria and received initial thyroidectomy at our department from January 2006 to December 2011 were enrolled in this study.Results After a median follow-up time of 7.8 years,distant metastases developed in 46 patients.Patients with lateral neck lymph node metastasis ≥7,individual size of lateral neck lymph node metastasis ≥ 1.15 cm and the total number of cervical lymph node metastasis ≥9 were prone to higher risk of distant metastasis;the high risk group had a lower 10-year distant metastasisfree survival (78.7％ vs.98％,x2 =122.941,P ＜0.01) and a shorter distant metastasis-free survival time (99.2 M vs.122.5 M,x2 =122.941,P ＜ 0.01).Conclusions Lateral lymph node metastasis is an independent risk factor for distant metastasis in PTC patients.

Asthma is the most common respiratory disease in childhood. It is one of the focuses of clinical nursing practice to pay attention to the preparation of children with asthma during the transition from hospital to family, meet the needs of children and main caregivers, and help children transition smoothly from hospital to family. Therefore, this article reviews the relevant theoretical models, research status, influencing factors, assessment tools and suggestions for improving the readiness for the hospital-family transition period in children with asthma, in order to provide reference for accurate assessment and intervention of transition readiness of children with asthma in China in the future.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

A 3-year-old male patient was diagnosed with neurofibromatosis type 1(NF1) for two years. The patient has multiple neurofibromas in retroperitoneum, lumbococcygeal paravertebral, lumbosacral spinal canal, and foramina. Due to retroperitoneal mass compression, the child suffered from urological complications such as hydronephrosis, ureterdilation, neurogenic bladder, etc., which seriously affected the urination function and resulted in multiple surgical treatments. Currently, the patient has been treated with mitogen activates extracelluar signal-regulated kinases(MEK) inhibitor selumetinib targeted therapy, and has voluntarily urinated, and his general state is better than before medication. The diagnosis and treatment of this case reflects the importance of multidisciplinary collaboration in the diagnosis and treatment of rare diseases.
