Chronic rhinosinusitis is a common disease and frequently encountered disease in otolaryngology, but the therapeutic effect is not ideal. While its pathogenesis is exploring in the continuously. Found in the recent years, Th17 cells are a new subset of T cells and closely related with inflammatory disorders, autoimmune diseases and cancer. Its differentiation, regulation and biological effects are widely noted as a hot area of research. This review explores the discovery of differentiation and regulation of Th17 cells, the relationship between related cytokines and chronic rhinosinusitis, in order to have a beteer knowledge of chronic rhinosinusitis. This review regards Th17 cells as the main clue, nevertheless, lacking consideration of the impacts of other factors on chronic rhinosinusitis.

ObjectiveBased on ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS）， the combination of serum pharmacochemistry， response profile of absorbed components in serum， network pharmacology and drug-likeness prediction was used to screen the potential active ingredients of Yanghetang against breast cancer. MethodsUPLC-Q-TOF-MS/MS was used to identify the main components in different solvent extracts of Yanghetang， and serum pharmacochemistry was applied to analyze the absorbed components from the serum of female SD rats after 0.5， 1， 2 h of administration. Combined with the response characteristic values of serum drug components obtained from UNIFI 1.8.2， the absorbed prototype components and metabolites were screened to get the absorbed components of Yanghetang with a significant patterns of elimination and growth. Network pharmacology was applied to construct a drug-component-pathway-target-disease network， and molecular docking was performed between absorbed components and key targets of breast cancer， and the drug similarity was analyzed by SwissADME. ResultsForty-two compounds were identified in Yanghetang samples extracted with different solvents， of which 16 compounds were common to the three different extraction solvents（methanol， 50% methanol and water）. The results of drug-containing serum analysis showed that there were 16 absorbed components in serum， including 5 prototypes and 11 metabolites. Network pharmacology results showed that Yanghetang against breast cancer involved 15 key targets such as proto-oncogene tyrosine-protein kinase Src（SRC）， epidermal growth factor receptor（EGFR） and phosphoinositide 3 kinase catalytic alpha polypeptide（PIK3CA）. Molecular docking results showed that 16 potential active ingredients were well combined with the predicted targets. Combined with drug likenesses， 12 compounds in the absorbed components of Yanghetang were considered to have potential for anti-breast cancer activity， mainly including α-pinene and γ-eudesmol and their metabolites， of which one was from Ephedrae Herba， one was from Rehmanniae Radix， and eight were from Cinnamomi Cortex. ConclusionThe chemical components of Yanghetang mainly include polysaccharides， monoterpene glycosides and coumarins， and its prototype components mainly undergo oxidation， hydrolysis and acetylation after entering the blood. Its anti-breast cancer mechanism may be related to the regulation of signaling pathways such as the mitogen-activated protein kinase（MAPK） and phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt）. The results of this study can lay a foundation for further exploration of Yanghetang in the treatment of breast cancer.

Objective To investigate whether iron mass induces HO-1 overexpression and explore the role of HO-1 in rat intracerebral hemorrhage(ICH). Methods In this study,144 hydrated chloride aldehyde-anesthetized Sprague- Dawley rats were used,autologous blood were injected into the right caudate nucleus to establish the ICH model.Saline injection and health were served as controls.Deferoxamine(DFO)with an intraperitoneal injection served as intervention group.Enhanced Perl's reaction was used for iron staining and brain iron deposits were determined.Brain HO-1 level were examined by immunohistochemical analysis and reverse transcription polymerase chain reaction(RT-PCR). Results There was a 21-fold increase in iron deposits around the hematoma 7 days after the infusion of 100 μl of autologous blood.Markedly increased levels of perihematomal HO-1 immunoreactivity and HO-1 mRNA in all ICH rats were detected at 3-14 days.The addition of DFO significantly reduced iron deposits in the ipsilateral basal ganglia at 7-14 days after ICH.DFO also inhibited HO-1 overexpression at day 7,14.Correlations test showed that there were positive correlations of iron sediments with HO-1mRNA(r=0.647)and HO-1 immunopositive cells(r=0.209). Conclusions ICH causes iron accumulation in the brain.Iron overloading may induce HO-1 upregulation after ICH.Ratherly,the HO-1 moderate increasing possibly fits with the events,whereas HO-1 overexpression may result in its dysfunction.It may be prudent to intervene ICH with HO-1 inhibitor.

OBJECTIVE: To analyze genetic variant in a pedigree affected with congenital high myopia. METHODS: Whole exome sequencing (WES) was carried out for the proband. Suspected variation was verified with Sanger sequencing. The pedigree was also subjected to co-segregation analysis. RESULTS: WES has identified a novel splice site heterozygous variant (c.2556+1G>A) in the COL11A1 gene in the proband. Co-segregation analysis of the pedigree showed that the affected mother and two daughters of the proband have carried the same variant(c.2556+1G>A), while his unaffected father and sister did not. Based on the ACMG Standards and Guidelines for the Interpretation of Sequence Variants, the variant was classified as "likely pathogenic" (PVS1+PM2). CONCLUSION A novel splice variant (c.2556+1G>A) of the COL11A1 gene has been identified in a pedigree affected with congenital high myopia, which probably underlies the disease.

Objective To evaluate the effect of preoperative pulmonary artery pressure on perioperative prognosis of the recipients with end-stage heart failure undergoing heart transplantation. Methods Clinical data of 105 recipients receiving heart transplantation were retrospectively analyzed. The mean pulmonary artery pressure (mPAP) was used as the diagnostic criterion. The optimal cut-off value of mPAP for predicting perioperative prognosis of heart transplant recipients was determined. According to the optimal cut-off value of mPAP, all recipients were divided into the low mPAP group (n=66) and high mPAP group (n=39). Intraoperative indexes (cardiopulmonary bypass time, aortic occlusion time, assisted circulation time and cold ischemia time of donor heart) and postoperative indexes [intra-aortic balloon pump (IABP) support rate, IABP support time, extracorporeal membrane oxygenation (ECMO) support rate, ECMO support time, mechanical ventilation time, length of ICU stay, incidence of moderate and severe tricuspid regurgitation and perioperative mortality rate] were compared between the low and high mPAP groups. The prognosis of the two groups was compared. Results The optimal cut-off value of mPAP in predicting clinical prognosis of heart transplant recipients was 30.5 mmHg. In the high mPAP group, the ECMO support rate and perioperative mortality rate were higher than those in the low mPAP group (both P < 0.05). No significant differences were observed in the cardiopulmonary bypass time, aortic occlusion time, assisted circulation time, cold ischemia time of donor heart, IABP support rate, IABP support time, ECMO support time, mechanical ventilation time, length of ICU stay and incidence of moderate and severe tricuspid regurgitation between two groups (all P > 0.05). No significant differences were noted in the 1-, 2-, 3- and 4- survival rates between two groups (all P > 0.05). Conclusions Preoperative mPAP in patients with end-stage heart failure is intimately correlated with perioperative prognosis of heart transplant recipients. The optimal cut-off value of mPAP in predicting perioperative prognosis of heart transplant recipients is 30.5 mmHg. In the high mPAP group, perioperative ECMO support rate and perioperative mortality rate are high, which do not affect the medium and long-term prognosis of the recipients undergoing heart transplantation.

OBJECTIVE: The clinical symptoms of diarrhea-predominant irritable bowel syndrome (IBS-D) can be effectively improved by traditional Chinese medicine (TCM) treatment, based on the usage of specific therapies for different TCM syndromes. However, in the stage of diagnosis, the standard criteria for the classification of TCM syndrome were still deficient. Through serum metabolic profiling, this study aimed to explore potential biomarkers in IBS-D patients with different TCM syndromes, which can assist in diagnosis of the disease. METHODS: Serum samples were collected from healthy controls (30 cases), IBS-D patients with Liver-Stagnation and Spleen-Deficiency syndrome (LSSD, 30 cases), Yang Deficiency of Spleen and Kidney syndrome (YDSK, 11 cases) and Damp Abundance due to Spleen-Deficiency syndrome (DASD, 22 cases). Serum metabolic profiling was conducted by ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. The potential biomarkers were screened by orthogonal partial least square-discriminate analysis, while metabolic pathways undergoing alterations were identified by pathway enrichment analysis in MetaboAnalyst 4.0. RESULTS: Overall, 34 potential biomarkers were identified in LSSD group, 36 in YDSK group and 31 in DASD group. And the 13 metabolites shared by three groups were determined as the potential biomarkers of IBS-D. Glycerophospholipid metabolism was disturbed significantly in IBS-D patients, which may play a role in IBS-D through inflammation. What's more, three TCM syndromes have the specific potential biomarkers in glycerophospholipid metabolism. CONCLUSION The serum metabolomics revealed that different TCM syndrome types in IBS-D may have different metabolic patterns during disease progression and glycerophospholipid metabolism was one of the pathways, whose metabolism was disturbed differently among three TCM syndromes in IBS-D. Therefore, the specific potential biomarkers in glycerophospholipid metabolism of three TCM syndromes in IBS-D can serve as the objective indicators, which can facilitate the TCM-syndrome objective classification of IBS-D.

OBJECTIVE: To analyze a pathogenic variant of MEFV gene in a family with autosomal dominant-familial Mediterranean fever (AD-FMF). METHODS: A 5-year-old boy presented with recurrent aseptic meningitis and his major symptoms included recurrent fever with headache and vomiting. His family members including his mother, sister and brother also had recurrent fever. A genetic disease was considered. DNAs were extracted from patient and all his family members' blood samples. Whole exome sequencing was performed to identify putative pathogenic variants that can explain this family's condition and Sanger sequencing was conducted. The impact of detected variants were predicted and validated by bioinformatics. RESULTS: A missense variant c.2229C>G (p.Phe743Leu) in MEFV gene was identified in the proband and his family members including his mother, sister and brother. This variant had not been reported in China previously, but the locus of it had already been reported in Arabic patient with AD-FMF (PS1). This variant was absent in major allele frequency databases (PM2) and had been predicted to be pathogenic based on Mutationtaster, PROVEAN and PolyPhen-2. In addition, the change of amino acid, locating in 743 locus of pyrin protein, encoding by MEFV gene, was found to cause SPRY_PRY_TRIM20 and SPRY_superfamily domain destroyed and finally influenced the fuction of pyrin protein. On the other hand, using UCSF chimera software, we find the variant c.2229C>G (p.Phe743Leu) can induce serious influence to the spatial structure of pyrin protein and loss of protein fuction (PP3). According to the ACMG variant classification guideline, the variant c.2229C>G (p.Phe743Leu) in MEFV gene was classified as likely pathogenic (PS1+PM2+PP3). CONCLUSION The condition of this AD-FMF family may be attributed to the missense variant c.2229C>G (p.Phe743Leu) in MEFV gene. The recurrent aseptic meningitis was a very rare manifestation in AD-FMF patients and had not been reported in China previously. The clinical and genetic findings of the present study are helpful for the further understanding of AD-FMF.
