RESUMO
【Objective】 To describe the distribution characteristics of knee and ankle joint range of motion and muscle atrophy related indexes in patients with Kashin-Beck disease (KBD) in Shaanxi Province so as to explore the correlation of knee and ankle joint range of motion (ROM) with muscle atrophy indexes and provide reference for clinical characteristics analysis of KBD patients. 【Methods】 To investigate the registered KBD patients from KBD areas in Shaanxi Province, we measured the general demographic data of the patients were collected and the ROM of the knee joint (flexion and extension), the ankle joint (dorsiflexion and plantar flexion), and the muscle atrophy related indexes such as the upper arm circumference, thigh circumference, calf circumference and grip strength. According to the population characteristics, i.e., gender, age, body mass index (BMI) and KBD grade, the median and quartile of joint ROM and muscle atrophy of KBD patients were reported, and then the differences in each index among different groups were analyzed. Partial correlation analysis was used to explore the correlation between indicators after controlling for variables such as gender, age and BMI. 【Results】 A total of 480 patients with KBD were investigated in this study, who consisted of 249 (51.9%) males and 231 (48.1%) females, with an average age of (63.10±7.32) years and an average BMI of (23.49±8.90) kg/m2. The knee flexion ROM, knee extension ROM, ankle dorsiflexion ROM and ankle plantar flexion ROM were [105.0 (95.0, 120.0)] °, [0.0 (-15.0, 0.0)] °, [5.0 (0.0, 15.0)] ° and [20.0 (15.0, 30.0)] °, respectively, in KBD patients in Shaanxi Province. The left thigh circumference, right thigh circumference, left calf circumference, right calf circumference, and upper arm circumference were [43.0 (40.0, 47.0)] cm, [43.0 (39.0, 47.0)] cm, [29.0 (27.0, 32.0)] cm, [29.5 (27.0, 32.0)] cm, [27.0 (25.0, 30.0)] cm, respectively. The left hand grip strength and right hand grip strength were [13.4 (9.5, 18.4)] kg and [13.9 (9.8, 18.2)] kg, respectively. With the increase of age, the extension range of the left and right knee joints of KBD patients showed a decreasing trend (H=31.499, 31.847; all P<0.001). The range of motion of bilateral knee flexion was higher in the normal BMI group than in the overweight or obese group, with statistically significant differences (H=7.753, 12.333; P=0.021, 0.002). The knee flexion, thigh circumference, and calf circumference of the left and right sides showed a decreasing trend under different KBD grades (H=14.345, 17.256, 8.000, 8.462, 8.558, 9.633; all P<0.05). Correlation analysis showed that knee flexion ROM was positively correlated with thigh circumference, calf circumference, and grip strength in patients with KBD (all P<0.05). There was a positive correlation between knee extension ROM and thigh circumference in patients with KBD (P<0.01). 【Conclusion】 The impaired joint ROM and muscle atrophy are serious in KBD patients in Shaanxi Province, and there is a correlation between joint motion and muscle atrophy.

RESUMO
Objective: To investigate the effects of human umbilical cord mesenchymal stem cells (hUCMSCs) combined with autologous Meek microskin transplantation on patients with extensive burns. Methods: The prospective self-controlled study was conducted. From May 2019 to June 2022, 16 patients with extensive burns admitted to the 990th Hospital of PLA Joint Logistics Support Force met the inclusion criteria, while 3 patients were excluded according to the exclusion criteria, and 13 patients were finally selected, including 10 males and 3 females, aged 24-61 (42±13) years. A total of 20 trial areas (40 wounds, with area of 10 cm×10 cm in each wound) were selected. Two adjacent wounds in each trial area were divided into hUCMSC+gel group applied with hyaluronic acid gel containing hUCMSCs and gel only group applied with hyaluronic acid gel only according to the random number table, with 20 wounds in each group. Afterwards the wounds in two groups were transplanted with autologous Meek microskin grafts with an extension ratio of 1∶6. In 2, 3, and 4 weeks post operation, the wound healing was observed, the wound healing rate was calculated, and the wound healing time was recorded. The specimen of wound secretion was collected for microorganism culture if there was purulent secretion on the wound post operation. In 3, 6, and 12 months post operation, the scar hyperplasia in wound was assessed using the Vancouver scar scale (VSS). In 3 months post operation, the wound tissue was collected for hematoxylin-eosin (HE) staining to observe the morphological changes and for immunohistochemical staining to observe the positive expressions of Ki67 and vimentin and to count the number of positive cells. Data were statistically analyzed with paired samples t test and Bonferronni correction. Results: In 2, 3, and 4 weeks post operation, the wound healing rates in hUCMSC+gel group were (80±11)%, (84±12)%, and (92±9)%, respectively, which were significantly higher than (67±18)%, (74±21)%, and (84±16)% in gel only group (with t values of 4.01, 3.52, and 3.66, respectively, P<0.05). The wound healing time in hUCMSC+gel group was (31±11) d, which was significantly shorter than (36±13) d in gel only group (t=-3.68, P<0.05). The microbiological culture of the postoperative wound secretion specimens from the adjacent wounds in 2 groups was identical, with negative results in 4 trial areas and positive results in 16 trial areas. In 3, 6, and 12 months post operation, the VSS scores of wounds in gel only group were 7.8±1.9, 6.7±2.1, and 5.4±1.6, which were significantly higher than 6.8±1.8, 5.6±1.6, and 4.0±1.4 in hUCMSC+gel group, respectively (with t values of -4.79, -4.37, and -5.47, respectively, P<0.05). In 3 months post operation, HE staining showed an increase in epidermal layer thickness and epidermal crest in wound in hUCMSC+gel group compared with those in gel only group, and immunohistochemical staining showed a significant increase in the number of Ki67 positive cells in wound in hUCMSC+gel group compared with those in gel only group (t=4.39, P<0.05), with no statistically significant difference in the number of vimentin positive cells in wound between the 2 groups (P>0.05). Conclusions: The application of hyaluronic acid gel containing hUCMSCs to the wound is simple to perform and is therefore a preferable route. Topical application of hUCMSCs can promote healing of the autologous Meek microskin grafted area in patients with extensive burns, shorten wound healing time, and alleviate scar hyperplasia. The above effects may be related to the increased epidermal thickness and epidermal crest, and active cell proliferation.

RESUMO
Objective:To investigate the role of a disintegrin and metalloprotease 12 (ADAM12) gene in chondrocyte injury in patients with Kashin-Beck disease (KBD) and its impact on genes related to insulin-like growth factor binding protein (IGFBP).Methods:Articular cartilage samples were obtained from 5 patients with KBD and 5 control subjects admitted to Honghui Hospital Affiliated to Xi'an Jiaotong University. Chondrocytes were extracted and cultured in vitro. Quantitative real-time PCR (qRT-PCR) and Western blotting were used to detect the expression levels of ADAM12 mRNA and protein in chondrocytes of patients with KBD and control subjects, respectively. Subsequently, ADAM12 gene overexpression was performed using lentivirus in chondrocytes of patients with KBD. MTT assay was used to detect changes in cell viability after ADAM12 gene overexpression, and qRT-PCR was used to detect the mRNA expression levels of chondrocyte differentiation related genes SRY-box transcription factor 9 (SOX9) and type Ⅱ collagen (COLⅡ), apoptosis-related gene B-cell lymphoma/leukaemia-2-associated X protein (BAX), and anabolic related genes IGFBP3 and IGFBP5. Results:The expression levels of ADAM12 mRNA and protein in chondrocytes of patients with KBD (0.57 ± 0.05, 0.81 ± 0.07) were significantly lower than those of control subjects (1.00 ± 0.00, 1.00 ± 0.00), and the differences were statistically significant ( t = - 24.50, - 3.61, P < 0.05). The results of MTT assay showed that the cell viability of chondrocytes in ADAM12 overexpression group (1.09 ± 0.05) was higher than that in empty vector control group (1.00 ± 0.08), and the difference was statistically significant ( t = 4.12, P = 0.031). The results of qRT-PCR showed that compared with empty vector control group, the mRNA expression levels of IGFBP3 (2.35 ± 0.79 vs 0.96 ± 0.25), IGFBP5 (2.13 ± 0.30 vs 0.98 ± 0.34), SOX9 (2.92 ± 0.51 vs 0.94 ± 0.36) and COLⅡ (6.45 ± 2.81 vs 0.87 ± 0.19) in ADAM12 overexpression group were significantly increased, and the differences were statistically significant ( t = 3.19, 5.16, 6.27, 4.10, P < 0.05); while the expression level of BAX mRNA (0.31 ± 0.06 vs 1.02 ± 0.22) was significantly decreased, and the difference was statistically significant ( t = - 11.16, P < 0.001). Conclusion:The ADAM12 gene may have a role in inhibiting apoptosis and promoting differentiation in chondrocyte injury in patients with KBD, and its overexpression can increase expression of IGFBP3 and IGFBP5.
RESUMO
Objective:To investigate the impact of matrix metalloproteinase 13 (MMP13) and low-density lipoprotein receptor-related protein 1 (LRP1) on autophagy of articular chondrocytes in patients with Kashin-Beck disease (KBD).Methods:Human articular cartilage samples obtained from 4 KBD patients and 4 control subjects were collected from Shaanxi Institute for Endemic Disease Prevention and Control, and the expression levels of MMP13 and LRP1 in cartilage tissue were determined using immunohistochemistry (IHC). Chondrocytes were extracted and cultured in vitro, the mRNA and protein expression levels of LRP1 and the autophagy related genes [Beclin 1 (BECN1), microtubule associated protein 1 light chain 3 (LC3)], cartilage injury related genes [MMP13, caspase-3 (CASP3)], chondrocyte differentiation related genes [collagen type Ⅱ alpha 1 chain (COL2A1), and SRY-box transcription factor 9 (SOX9)] were detected by real-time fluorescence quantitative PCR (qRT-PCR) and Western blot (WB), respectively. Chondrocytes from 3 KBD patients were extracted, and MMP13 gene silencing experiment was performed by RNA interference (RNAi) technology, the mRNA and protein expression levels of the above genes were detected by qRT-PCR and WB, respectively. In addition, the antagonist receptor associated protein (RAP) of LRP1 was used to block the LRP1 of human normal chondrocytes (C28/I2 cells), and qRT-PCR and WB were used to detect the mRNA and protein expression levels of LRP1, chondrocyte autophagy, differentiation and cartilage injury related genes, respectively. Results:The IHC results showed that the expression levels of MMP13 (1.67 ± 0.21, 0.59 ± 0.15, 0.51 ± 0.12) in the surface, middle, and deep layers of cartilage tissue of KBD patients were significantly higher than those of control subjects (0.25 ± 0.03, 0.26 ± 0.04, 0.06 ± 0.01), and the differences were statistically significant ( t = - 11.38, P < 0.001; t = - 3.82, - 6.26, P = 0.019, 0.003). The expression levels of LRP1 (0.10 ± 0.02, 0.03 ± 0.01, 0.17 ± 0.03) were significantly lower than those of control subjects (1.63 ± 0.40, 0.44 ± 0.12, 0.34 ± 0.08), and the differences were statistically significant ( t = 6.61, 5.61, 3.64, P = 0.003, 0.005, 0.022). The mRNA and protein expression levels of MMP13, CASP3, SOX9 in chondrocytes of KBD patients were significantly higher than those of control subjects, and the differences were statistically significant ( P < 0.05). The mRNA expression levels of LRP1, LC3, COL2A1 were significantly lower than those of control subjects, and the differences were statistically significant ( P < 0.05). After silencing the MMP13 gene in chondrocytes of KBD patients, there were no significant differences in the mRNA and protein expression levels of LRP1, BECN1, LC3, CASP3, COL2A1, and SOX9 ( P > 0.05). After blocking LRP1 with RAP, the protein expression levels of LRP1, BECN1, LC3, MMP13, COL2A1 and SOX9 in chondrocytes were significantly lower than those in control group ( P < 0.05). Conclusions:There is no direct correlation between MMP13 and abnormal autophagy of articular chondrocytes in KBD patients. After blocking LRP1, the expression of the autophagy related genes BECN1 and LC3 in chondrocytes is decreased.
RESUMO
Objective:To analyze the surgical types of patients with Kashin-Beck disease (KBD) in Shaanxi Province, and to provide reference for optimizing KBD surgery.Methods:Retrospective analysis was used to investigate KBD patients who underwent surgical treatment, and the patient's information was from the Shaanxi Provincial Endemic Disease Prevention and Control Information System. Patients with incomplete surgical treatment information were excluded, and χ 2 test was used to analyze the impact of factors such as gender, education level, living area, disease severity, and social environment on the selection of different surgical types (free body enucleation or joint replacement) for KBD patients. Using propensity score method to perform a 1 ∶ 1 match on patients with different surgical types, and analyzing the influencing factors of KBD patients receiving different types of surgical treatment through multivariate logistic regression. Results:From 2018 to 2020, a total of 1 084 KBD patients in Shaanxi Province underwent surgical treatment, including 555 males (51.20%) and 529 females (48.80%), with a median age of 64 years old. There were 917 patients (84.59%) in the Guanzhong region (Tongchuan, Xi'an, Weinan, Xianyang, Baoji), 120 patients (11.07%) in the northern Shaanxi region (Yulin, Yan'an), and 47 patients (4.34%) in the southern Shaanxi region (Ankang, Hanzhong, Shangluo). The number of patients with KBD grade Ⅰ,Ⅱ, and Ⅲ was 401 (36.99%), 525 (48.43%), and 158 (14.58%), respectively. Five hundred and forty-eight patients (50.55%) underwent free body enucleation surgery, and 536 patients (49.45%) underwent joint replacement surgery. Univariate analysis showed that different genders, educational levels, living areas, disease severity, economic status, whether to relocate, type of drinking water, type of staple food, and source of staple food were the influencing factors for KBD patients to choose the type of surgery (χ 2 = 81.82, 22.38, 93.68, 22.38, 5.17, 15.68, 13.82, 39.37, 49.63, P < 0.05). Among 374 pairs of patients who underwent free body enucleation and joint replacement through propensity score matching, multivariate logistic regression analysis found that high school and above education level [odds ratio( OR) = 0.42, P = 0.008], Guanzhong region ( OR = 0.12, P < 0.001), relocation ( OR = 0.60, P = 0.004), and drinking well water ( OR = 2.15, P = 0.001) were the influencing factors for KBD patients to choose different surgical types for treatment. Conclusion:When performing surgical treatment for KBD patients in Shaanxi Province, clinicians can consider the severity of the disease, as well as factors such as the education level, living area, relocation status, and type of drinking water of KBD patients, to provide more suitable surgical types for KBD patients.
RESUMO
Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative patient-controlled intravenous analgesia in pediatric patients undergoing lower extremity orthopedic surgery.Methods:Sixty-eight pediatric patients of both sexes, aged 3-15 yr, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, undergoing elective lower extremity orthopedic surgery under general anesthesia, were divided into 2 groups ( n=34 each) by the random number table method: TEAS group (group T) and control group (group C). In group T, the bilateral Hegu and Neiguan acupoints were stimulated starting from 10 min before induction of anesthesia until the end of procedure, with the frequency of disperse-dense wave of 2/10 Hz, and the current intensity was gradually adjusted to the maximum intensity (10-15 mA) that children could tolerate. In group C, the electrodes were applied to the same acupoints, but electrical stimulation was not applied. The severity of pain was assessed by the Faces Pain Scale-Revised scale immediately after returning to the ward and at 2, 24 and 48 h after operation. The emergence agitation was evaluated using the Pediatric Anesthesia Emergence Delirium scale. The intraoperative consumption of propofol and remifentanil and time to extubation after stopping administration were recorded. The time to first pressing of patient-controlled analgesia (PCA), effective pressing times of PCA on 1st and 2nd days after surgery and postoperative adverse reactions such as postoperative nausea and vomiting, pruritus, drowsiness, and respiratory depression were recorded. Results:Compared with group C, the Faces Pain Scale-Revised scale scores were significantly decreased immediately after returning to the ward and at 2, 24 and 48 h after operation, the incidence of emergence agitation and intraoperative consumption of remifentanil were decreased, the time to extubation was shortened, the time to first pressing of PCA was prolonged, and the effective pressing times of PCA on 1st and 2nd days after surgery were decreased ( P<0.05). There was no significant difference in the intraoperative consumption of propofol and incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:TEAS can effectively enhance the effect of postoperative patient-controlled intravenous analgesia in pediatric patients undergoing lower extremity orthopedic surgery.
RESUMO
Objective:To compare the changes of biliary microbiota after enteral extended biliary stents (EEBS) implantation with that of conventional plastic stents in animal experiment, and to preliminarily investigate its possible mechanism in preventing stents occlusion.Methods:A total of 12 healthy Bama minipigs were randomly assigned to the conventional plastic stent group ( n=6) and the EEBS group ( n=6) using simple random method. The bile samples of all pigs were collected before stents implantation and 4 weeks after stents placement. The biliary microbiota composition and diversity before and after different stents implantation were analyzed by 16S rRNA gene sequencing and compared. Results:No complications including acute cholangitis, perforation, bleeding, or death occurred in 12 pigs. Eight days after stents implantation, stents were out of bile duct in all pigs under endoscopy, while the bile samples were collected again for analysis. The main composition of biliary microbiota at the phylum level were Proteobacteria, Firmicutes and Bacteroidota. Alpha-diversities revealed the Shannon ( P=0.004) and Simpson index ( P=0.008) significantly decreased in the conventional stent group after stents placement, and Bata diversity analysis also showed a significant difference in microbial composition (Anosim: R=0.514 8, P=0.011). There was no significant difference in Observed species index ( P=0.095), Chao1 index ( P=0.136), Shannon index ( P=0.353), Simpson index ( P=0.227) or Bata diversity (Anosim: R=0.059 3, P=0.187) in the EEBS group before and after stents placement. LEfSe algorithm indicated Bacteroides_ fragilis and Proteobacteria- Gammaproteobacteria- Enterobacterales- Enterobacteriaceae- scherichia_ Shigella- Escherichia_ coli significantly increased in the conventional stent group, and Desulfobacterota- Desulfovibrionia- Desulfovibrionales- Desulfovibrionaceae- Bilophila significantly increased in the EEBS group after stents placement. Conclusion:The biliary microbiota change slightly after EEBS implantation in the short-term, and EEBS may prevent duodenobiliary reflux by prolonging the reflux path.
RESUMO
Objectives@#. Voice abuse in noisy environments can result in voice disorders. However, insufficient studies have sought to differentiate vocal cord lesions through laryngoscopic examinations among workers in noisy environments. This study investigated the relationship between a history of noise exposure in the workplace and benign vocal fold lesions (BVFLs). @*Methods@#. We used Korea National Health and Nutrition Examination Survey data from 2010 to 2012. The chi-square test was used to compare characteristics between two groups according to the presence or absence of BVFLs. To investigate the association between BVFLs and noise exposure in the workplace, we calculated adjusted odds ratios and 95% confidence intervals (CIs) using multiple logistic regression analysis. @*Results@#. In total, 10,170 participants with available laryngoscopy results were enrolled. Smoking history, hypertension, diabetes, and exposure to noise for more than 3 months at the workplace were significantly more common in participants with BVFLs. After adjusting for age, sex, smoking, drinking, obesity, hypertension, diabetes, income, education, and occupation as confounders, we confirmed that BVFLs were 1.52 times more likely (95% CI, 1.157–1.990) to occur in individuals with occupational noise exposure. @*Conclusion@#. Working in a noisy environment could induce BVFLs in workers through voice abuse. Social recognition that a noisy environment is a risk factor for BVFLs needs to be improved, and preventive measures should be implemented.
RESUMO
Background and Objectives@#Sialendoscopy is useful for the diagnosis and treatment of obstructive salivary gland diseases, but not yet universally employed because it requires dedicate, expensive, and fragile endoscopic equipment; moreover, the surgical technique is also delicate. Here, we describe our initial experience of sialendoscopy, as well as the learning curve, precautions, and drawbacks that beginners must overcome in employing sialendoscopy.Subjects and Method The medical records of 98 patients who underwent sialendoscopic procedures at Eunpyeong St. Mary’s Hospital from May 2019 to March 2022 were retrospectively reviewed. The type of procedure, success rate, operation time, and complications were analyzed. @*Results@#We have performed a total of 85 sialendoscopic procedures, including 79 to treat submandibular sialolithiasis, two to treat submandibular ductal stenosis, two to treat parotid sialolithiasis, and two to treat parotid ductal stenosis. Of the total of 81 patients with sialolithiasis, 82.4% were treated by sialendoscopy only, 15.3% by hybrid procedure, and 2.3% opted to preserve the salivary gland and convert to external submandibular gland excision. Four patients with ductal stenosis were treated via endoscopic bougination; stents were placed for 4 weeks without any restenosis. The operation time was significantly shorter for the second half than for the first half of the patients (58.6 min vs. 39.8 min). Longer operation time was associated with the parotid gland diseases, larger stones (>5 mm in diameter), more proximal stones (from the salivary gland), and multiple stones. We encountered no major surgical complications. @*Conclusion@#Sialendoscopy is useful and safe; even beginners can evaluate and manage obstructive salivary gland diseases.
RESUMO
OBJECTIVE@#To observe the effect of acupuncture combined with infantile tuina on intestinal flora and its efficacy in children with tic disorders (TD), and to explore its mechanism.@*METHODS@#A total of 15 children with TD were recruited as an observation group and 10 healthy children as a healthy control group. Regulating spleen and stomach acupuncture combined with infantile tuina were received in the observation group. First, acupuncture was applied to Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Hegu (LI 4), Zusanli (ST 36), etc., and then abdominal massage and other tuina techniques were applied, once a day, 6 times a week, 2 weeks as a course of treatment, a total of 2 courses of treatment were required. No intervention was given in the healthy control group. In the observation group, Yale global tic severity scale (YGTSS) score and TCM syndrome score were compared before treatment and after 1 and 2 courses of treatment. 16S rRNA sequencing technology was used to detect the intestinal flora in the healthy control group and before and after treatment in the observation group.@*RESULTS@#After 1 and 2 courses of treatment, the scores of YGTSS and TCM syndrome in the observation group were lower than those before treatment (P<0.01, P<0.05). Compared with the healthy control group, the number of operational taxonomic units (OTU) and indexes of Chao1, Sobs, Ace and Shannon were decreased in the observation group before treatment (P<0.05, P<0.01). Compared with before treatment, the number of OTU and indexes of Chao1, Sobs, Ace and Shannon were increased in the observation group after treatment (P<0.01, P<0.05). Compared with the healthy control group, the relative abundance of Firmicutes in the observation group before treatment was decreased (P<0.001), while the relative abundance of Bacteroidetes, Bacteroides and Erysipelatoclostridium was increased (P<0.001, P<0.05). Compared with before treatment, the relative abundance of Bacteroidetes in the observation group was decreased (P<0.001) after treatment, while the relative abundance of Actinobacteria, Bifidobacterium and Atopobium was increased (P<0.05, P<0.01).@*CONCLUSION@#Acupuncture combined with infantile tuina based on the principle of regulating spleen and stomach could effectively improve TD symptoms in children, which may be related to regulating the diversity of intestinal flora, increasing beneficial bacteria, maintaining intestinal microecological balance, and playing a role in improving neurological disorders.

Objective: To investigate the effects and clinical significance of NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome activated by interleukin (IL)-17A in chronic rhinosinusitis with nasal polyps (CRSwNP). Methods: Patients underwent nasal endoscopic surgery in the Third Affiliated Hospital of Sun Yat-sen University from January 2020 to December 2021 were collected, including 28 CRSwNP (including 19 males and 9 females, aged 19 to 67 years), 22 chronic rhinosinusitis without nasal polyps (CRSsNP) and 22 controls. qRT-PCR was used to detect the expressions of IL-17A, NLRP3, IL-1β and IL-18 in the three groups, and their correlations were analyzed. The positions of IL-17A, NLRP3 and IL-18 in nasal polys were analyzed by immunofluorescence. Western Blotting and ELISA were employed to detect the expression of NLRP3, IL-1β and IL-18 in the human nasal epithelial cells after using IL-17A stimulation or IL-17A receptor inhibitor. Immunofluorescence was used to observe the NLRP3, IL-1β, and IL-18 protein expression after IL-17A stimulating human nasal epithelial cells, and after the use of IL-17A receptor inhibitor and NLRP3 inhibitor MCC950. The correlations between NLRP3, IL-1β, IL-18 and CT scores, nasal endoscopic scores, visual analogue scale (VAS) scores, and sino-nasal outcome test (SNOT) 22 scores of CRSwNP patients were analyzed. SPSS 20.0 software was used for statistical analysis. Results: The expressions of IL-17A, NLRP3, IL-1β and IL-18 in the tissues of CRSwNP patients were significantly higher than those in CRSsNP group(P=0.018,P<0.001,P=0.005, P=0.016) and the control group(all P<0.001). IL-17A was positively correlated with the expression of NLRP3, IL-1β, and IL-18(r ralue was 0.643,0.650,0.629,respectively, all P<0.05). IL-17A, NLRP3, and IL-18 were co-localized in the epithelial propria of polyp tissue. IL-17A stimulated the expressions of NLRP3, IL-1β, and IL-18 in human nasal epithelial cells. After the use of IL-17A receptor inhibitor, the expressions of NLRP3, IL-1β, and IL-18 were significantly down-regulated. After the use of NLRP3 inhibitor MCC950, IL-17A was significantly down-regulated to promote the expression of NLRP3, IL-1β, and IL-18. The expressions of NLRP3, IL-1β and IL-18 were positively correlated with CT, nasal endoscopy, VAS, and SNOT22 scores in patients with CRSwNP. Conclusions: IL-17A promotes the release of IL-1β and IL-18 by activating the NLRP3 inflammasome and aggravates the severity of the disease in CRSwNP.
