TCM for the improvement of nasal mucosa remodeling after chronic sinusitis endoscopy is the key to the effective prevention of new lesions and recurrence in the surgical cavity mucosa.This article reviewed the mechanism of the nasal mucosa remodeling phenomenon after chronic sinusitis endoscopy and the unique advantages of TCM treatment.Deficiency,phlegm and blood stasis leading to"lung loss"is the perennial root of nasal mucosa remodeling.The treatment is"tonifying deficiency and removing phlegm,invigorating qi and promoting blood circulation",using acupuncture and medicine,and both internal and external treatment to regulate Th17/Treg balance and reduce the inflammatory infiltration;blocking the phosphorylation of MAPK and NF-κB pathway to inhibit TGF-β1-induced myofibroblasts,reduce collagen deposition and inhibit their remodeling,and promote the process of mucosal epithelialization,which can provide ideas for the theoretical and clinical treatment of TCM prevention and treatment of nasal mucosa remodeling.

Objective To investigate vascular remodeling and low-density lipoprotein(LDL)deposition,the growth and development trends of lateral branch plaques in bifurcated vessels,and the potential locations of subsequent plaque growth due to the presence of plaques.Methods An idealized model of bifurcated vessels was established and the distribution of wall shear stress before and after the growth of edge-branch plaques was obtained using computational fluid dynamics.Seven sections were intercepted in the areas of low shear stress:planes 1-3 were the low shear stress areas on the lateral branch before plaque formation,planes 4-5 were the proximal and distal edges of the plaque,and planes 6-7 were the lower shear stress areas of the plaque.Vascular remodeling and LDL deposition in the cross section were simulated.The growth and development trends of plaques are also discussed.Results Among planes 1-3,plane 2 produced obvious negative remodeling and the highest concentration of LDL deposition(102.266 mmol/L),thereby indicating that this was the initial location of the atherosclerotic plaque.Compared to plane 4,plane 5 produced more pronounced vascular remodeling,lumen narrowing,and the highest deposition concentration(110.17 mmol/L)after plaque formation,which indicated that the patch had a tendency for eccentric growth downstream.Compared to plane 6,plane 7(blood flow separation reattachment site)produced more negative remodeling and the highest deposition concentration(93.851 mmol/L),thereby indicating the possibility of new plaque formation near the reattachment point of blood flow separation.Conclusions Obvious vascular remodeling at low shear stress in the lateral branches leads to lumen stenosis and high LDL deposition,thus,forming atherosclerotic plaques.The lateral wall of the bifurcated blood vessels is the initial location of atherosclerotic plaque growth.After growth,the plaque tends to develop downstream,and subsequent plaques may form at the flow separation and reattachment points.

Objective: To investigate the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Shaoxing City from 2006 to 2022, so as provide insights into improvements of the HFRS control strategy. Methods: Data pertaining to HFRS cases in Shaoxing City from 2006 to 2022 were captured from the Surveillance System of China Information System for Disease Control and Prevention. The temporal, population and regional distributions of HFRS were analyzed using the descriptive epidemiological method, and the trends in incidence of HFRS were evaluated using annual percent change (APC). Results: Totally 1 022 HFRS cases were reported in Shaoxing City from 2006 to 2022, with annual average incidence of 1.22/105 and three deaths. The incidence of HFRS appeared a tendency towards a decline in Shaoxing City from 2006 to 2022 (APC=-11.101%, t=-9.930, P<0.001), and the incidence of HFRS peaked from May to June and from November to January of the next year. A higher incidence of HFRS was seen in men than in women (1.76/105 vs. 0.68/105; χ2=201.361, P<0.001). There were 714 HFRS cases at ages of 30 to 59 years (69.86%), and farmers were the predominant occupation (78.18%). The three counties with the largest number of HFRS cases included Zhuji (366 cases), Xinchang (263 cases) and Shengzhou (134 cases). The incidence of HFRS was lower in urban districts (Yuecheng, Keqiao and Shangyu) than in counties (Zhuji, Shengzhou and Xinchang) (0.58/105 vs. 1.96/105; χ2=326.880, P<0.001). Conclusion The incidence of HFRS appeared a tendency towards a decline in Shaoxing City from 2006 to 2022, and the incidence was high in late spring, early summer and winter. The HFRS cases were mainly males, young and middle-aged people, and farmers, and predominantly distributed in counties. Targeted control measures are needed.

Objective:To retrospectively analyze clinical efficacy and safety of omalizumab in the treatment of chronic urticaria (CU) in southern Zhejiang, China.Methods:A retrospective observational study was conducted on CU patients who received omalizumab treatment at the First Affiliated Hospital of Wenzhou Medical University from January 1st, 2018 to August 1st, 2021. Through the outpatient follow-up visits, the disease activity, condition control, and quality of life were evaluated using the 7-day urticaria activity score (UAS7) , urticaria control test (UCT) , and dermatology life quality index (DLQI) . In addition, changes in disease condition, recurrence after withdrawal, and adverse events were assessed. Independent-sample t test was used for intergroup comparisons of normally distributed measurement data, Wilcoxon signed-rank sum test or Kruskal-Wallis H test was used for comparisons of non-normally distributed measurement data, and chi-square test or Fisher′s exact test was used for comparisons of enumeration data. Results:A total of 252 CU patients with poor response to antihistamines were included, with a baseline UCT score of 5.0 ± 2.4 points, a UAS7 score of 25.6 ± 6.2 points, and a DLQI score of 17.5 ± 4.7 points; among them, 204 (81.0%) were treated with omalizumab at an initial dose of 300 mg, and 48 (19.0%) with omalizumab at an initial dose of 150 mg. At the end points (12.0 ± 1.4 months after the start of treatment) , an overall control rate of 90.3% (224/248) was achieved after the omalizumab treatment; concretely, 137 (55.2%) patients achieved complete control (UCT = 16 points) , 87 (35.1%) achieved partial control (12 points ≤ UCT < 16 points) , and 24 (9.7%) showed no response (UCT < 12 points) , while 10 with partial response shifted to complete control after dose increase. During the treatment period, recurrence occurred in 50 patients (36.5%) , of whom 32 patients opted for retreatment with omalizumab, and then 30 (93.8%) achieved partial or complete control. Adverse events were reported in 8 patients (3.2%) , and all were mild or moderate.Conclusion:Omalizumab was effective in the real-world treatment of CU, and could improve patients′ quality of life, with a favorable safety profile.

Objective To explore the changes and significance of Klotho protein levels in different stages of chronic kidney disease (CKD). Methods From March 2015 to December 2017,176 patients with CKD admitted to nephrology department of Inner Mongolia People＇s Hospital were selected as the study object (CKD group), and 80 healthy patients in our hospital were selected as the control group in the same period. The serum Klotho levels of CKD patients and control group at different stages were detected by double antibody sandwich ELISA, and the differences between each group were compared. Results The serum Klotho level of CKD group (( 4. 84 ± 1. 87) μg／L) was significantly lower than that of the control group ((9. 11± 3. 14) μg／L) ( t＝ 13. 82, P＜0. 01) . One-way anova showed that estimated renal glomerular filtration rate (eGFR),serum albumin (ALB),hemoglobin ( Hb),blood calcium ( Ca) and serum Klotho were gradually decreased,while phosphorus (P) and creatinine (Cr) in serum were gradually increased,and the difference was statistically significant among the five stages( all P＜0. 01). Spearman correlation analysis showed that Klotho level was positively correlated with eGFR and Ca,and negatively correlated with CKD stage,Cr and P (r＝0. 369,0. 160,－0. 200,－0. 250,－0. 230,all P＜0. 05). The multiple linear regression equation showed that Klotho level was positively and independently correlated with eGFR ( t＝ 3. 89, P＜0. 001),and negatively correlated with CKD staging independently (t＝－4. 12,P＜0. 001). Conclusion The expression level of serum Klotho protein in patients with CKD is lower than that of healthy people,and it decreases with the increase of CKD stages,which is closely related to the deterioration of renal function. It can be used as a reference index to evaluate the incidence and severity of CKD.
