AIM: To investigate the effects of genistein on the expression of nuclear factor-?B (NF-?B) and the levels of tumor necrosis factor-? (TNF-?) in peripheral blood mononuclear cells (PBMCs) of asthma patients. METHODS: PBMCs were isolated from blood samples of 32 asthma patients and 31 healthy persons, which was divided into control groups, dexamethasone-treated groups and genistein-treated groups. The expression of NF-?B was analyzed by immunocytochemical staining. The level of TNF-? was measured by radioimmunoassay. RESULTS: The percentage of NF-?B-positive cells in PBMCs and the level of TNF-? in PBMCs culture supernatants were significantly higher in asthma patients than in healthy persons (all P

Purpose: RIOK1 has been proved to play an important role in cancer cell proliferation and migration in various types of cancers—such as colorectal and gastric cancers. However, the expression of RIOK1 in breast cancer (BC) and the relationship between RIOK1 expression and the development of BC are not well characterized. In this study, we assessed the expression of RIOK1 in BC and evaluated the mechanisms underlying its biological function in this disease context. Materials and Methods: We used immunohistochemistry, western blot and quantitative real-time polymerase chain reaction to evaluate the expression of RIOK1 in BC patients. Then, knockdown or overexpression of RIOK1 were used to evaluate the effect on BC cells in vitro and in vivo. Finally, we predicted miR-204-5p could be a potential regulator of RIOK1. Results: We found that the expression levels of RIOK1 were significantly higher in hormone receptor (HR)–negative BC patients and was associated with tumor grades (p=0.010) and p53 expression (p=0.008) and survival duration (p=0.011). Kaplan-Meier analysis suggested a tendency for the poor prognosis. In vitro, knockdown of RIOK1 could inhibit proliferation, invasion, and induced apoptosis in HR-negative BC cells and inhibited tumorigenesis in vivo, while overexpression of RIOK1 promoted HR-positive tumor progression. MiR-204-5p could regulate RIOK1 expression and be involved in BC progression. Conclusion These findings indicate that RIOK1 expression could be a biomarker of HR-negative BC, and it may serve as an effective prognostic indicator and promote BC progression.

Objective: To observe the effects of Fufang Lishao Pills (FFLSP) on the proinflammatory factors, pain-relatedproteins and JAK2/STAT3 signaling pathways in nitroglycerin-induced chronic migraine model, and exploring thepharmacological target and mechanism of FFLSP on chronic migraine rats. Methods: Male Sprague-Dawley rats wererandomly divided into 6 groups: Control, Migraine, FFLSP-L (420 mg·kg-1), FFLSP-M (840 mg·kg-1), FFLSP-H (1680mg·kg-1) and Flunarizine Hydrochloride group (FH, 1 mg·kg-1) . Chronic migraine model was made by subcutaneousinjection of nitroglycerin (10 mg·kg-1) once every 3 days for 5 times. The rats were treated with FFLSP by intragastricadministration once a day for 30 days. Western blot was used to detect the protein expression of iNOS, COX-2, CGRPand c-Fos and the phosphorylation levels of JAK2 and STAT3 in cortex of rats. The production of IL-1β and TNF-αwere detected by enzyme linked immunosorbent assay (ELISA) . Results: Compared with Control rats, and the level ofiNOS, COX-2, CGRP, c-Fos expression (P ＜ 0.01) and IL-1β, TNF-α production remarkably up-regulated (P ＜ 0.05), and the phosphorylation of JAK2 and STAT3 also significantly increased in cotex of Migrainerats (P ＜ 0.01) . However, compared with Migrainerats, the levels of iNOS, COX-2, CGRP, c-Fos expression and IL-1β, TNF-α productionobviously declined (P ＜ 0.05; P ＜ 0.01), and the phosphorylation level of JAK2 and STAT3 showed a significantlydecrease in the cortex of Migraine rats with FFLSP treatment (P ＜ 0.01) . Conclusion: This study demonstrates that thepharmacological mechanism of FFLSP in improving chronic migraine may be achieved by inhibiting neuroinflammationthrough the blockage of JAK2/STAT3 pathwayin the cortex of rat with nitroglycerin induction.

There were 346 males and 395 females, aged 55(range, 17?86)years. Observation indicators: (1) neoadjuvant treatment; (2) surgical and postoperative situations; (3) follow-up; (4) stratified analysis. Follow-up was conducted using outpatient examination or telephone interview. Patients were followed up once every 3?6 months during neoadjuvant therapy and once every 6?12 months after radical surgery to detect tumor recurrence and survival of patient up to April 2022. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using chi-square test or Fisher exact probability. The Kaplan-Meier method was used to draw survival curves and calculate survival rates. Log-rank test was used for survival analysis. The COX regression model was used for univariate and multivariate analyses. Propensity score matching was done by the 1∶1 nearest neighbor matching method, and the matching tolerance was 0.02. Results:(1) Neoadjuvant therapy. Of the 741 patients, 34 cases received neoadjuvant therapy for 8(range, 3?44)months. Cases assessed as partial response, stable disease and progressive disease before the radical surgery of the 34 cases were 21, 9, 4, respectively. The tumor diameter of the 34 patients before the neoadjuvant therapy and before the radical surgery were 8.0(range, 3.0?26.0)cm and 5.3(range, 3.0?18.0)cm, with the regression rate as 31.9%(range, ?166.7% to 58.3%). (2) Surgical and postoperative situations. Of the 741 patients, 34 cases underwent radical surgery after receiving neoadjuvant therapy, and 707 cases underwent radical surgery directly. All the 741 patients underwent radical surgery successfully, in which 633, 102 and 6 cases received open surgery, laparoscopic surgery and endoscopic treatment, respectively. Of the 633 cases receiving open surgery and the 102 cases receiving laparoscopic surgery, cases with surgical resection range as pancreatoduodenectomy (PD) was 238, and cases with surgical resection range as duodenal limited resection, including duodenal wedge resection, distal gastrectomy, segmental duodenal resection, local resection of duodenal tumor or segmental duodenum combined with subtotal gastrectomy, was 497, 226, 55, 204, 12. Of the 741 patients, 131 cases had post-operative complications including 113 cases with grade Ⅰ?Ⅱ complications and 18 cases with ≥ grade Ⅲ complications of the Clavien-Dindo classification. The duration of postoperative hospital stay of the 741 patients was 13(range, 4?120)days. Of the 707 patients receiving direct radical surgery, 371 cases were evaluated as extremely low risk, low risk, medium risk of the modified National Institutes of Health (NIH) risk classification after surgery, and 336 cases were evaluated as high risk in which 205 cases receive postoperative adjuvant imatinib therapy with the treatment time as 24(range, 6?110)months. (3) Follow-up. All the 741 patients were followed up for 58(range, 7?150)months. During the follow-up, 110 patients had tumor recurrence and metastasis. The 1-, 3-, 5-year overall survival rates and 1-, 3-, 5-year disease-free survival rates of the 741 patients were 100.0%, 98.6%, 94.5% and 98.4%, 90.9%, 84.9%, respectively. The 1-, 3-, 5-year overall survival rates and 1-, 3-, 5-year disease-free survival rates of the 707 patients receiving direct radical surgery were 100.0%, 98.5%, 94.3% and 98.4%, 91.1%, 85.4%, respectively. (4) Stratified analysis. ① Analysis of prognostic factors in patients undergoing radical surgery directly. Results of univariate analysis showed that primary tumor location, tumor diameter, mitotic count, modified NIH risk classification and tumor gene information were related factors affecting the overall survival of 707 patients with primary duodenal GIST who underwent direct radical surgery ( hazard ratio=0.43, 0.18, 0.22, 0.06, 0.29, 95% confidence intervals as 0.20?0.93, 0.09?0.35, 0.10?0.50, 0.03?0.12, 0.09?0.95, P<0.05). The primary tumor location, tumor diameter, mitotic count, modified NIH risk classification were related factors affecting the disease-free survival of 707 patients with primary duodenal GIST who underwent direct radical surgery ( hazard ratio=0.65, 0.25, 0.25, 0.10, 95% confidence intervals as 0.41?1.03, 0.17?0.37, 0.15?0.42, 0.07?0.15, P<0.05). Results of multivariate analysis showed that primary tumor located at the horizontal segment of duodenum, mitotic count >5/50 high power field, tumor gene KIT exon 9 mutation were independent risk factors affecting the overall survival of 365 patients with primary duodenal GIST after removing 342 patients without tumor gene information who underwent direct radical surgery ( hazard ratio=2.85, 2.73, 3.13, 95% confidence intervals as 1.12?7.20, 1.07?6.94, 1.23?7.93, P<0.05). Tumor diameter >5 cm and mitotic count >5/50 high power field were independent risk factors affecting the disease-free survival of 707 patients with primary duodenal GIST who underwent direct radical surgery ( hazard ratio=3.19, 2.98, 95% confidence intervals as 2.05?4.97, 1.99?4.45, P<0.05). ② Effect of postoperative adjuvant therapy on prognosis of high-risk patients of modified NIH risk classification. Of the 336 patients evaluated as high risk of the modified NIH risk classification, the 5-year overall survival rate and 5-year disease-free survival rate were 94.6% and 77.3% in the 205 cases with postoperative adjuvant therapy, versus 83.2% and 64.4% in the 131 cases without postoperative adjuvant therapy, showing significant differences between them ( χ2=8.39, 4.44, P<0.05). Of the 205 patients evaluated as high risk of the modified NIH risk classification who received postoperative adjuvant therapy, there were 106 cases receiving postoperative adjuvant therapy <36 months, with the 5-year overall survival rate and 5-year disease-free survival rate were 87.1% and 58.7%, and there were 99 cases receiving post-operative adjuvant therapy ≥36 months, with the 5-year overall survival rate and 5-year disease-free survival rate were 100.0% and 91.5%. There were significant differences in the 5-year overall survival rate and 5-year disease-free survival rate between the 106 patients and the 99 patients ( χ2=13.92, 29.61, P<0.05). ③ Comparison of clinical efficacy of patients with different surgical methods. Before propensity score matching, cases with primary tumor located at bulb, descending, horizontal, ascending segment of duodenum, cases with tumor diameter ≤5 cm and >5 cm were 95, 307, 147, 34, 331, 252, in the 583 patients receiving open surgery with complete clinical data, versus 15, 46, 17, 5, 67, 16 in the 83 patients receiving laparoscopic surgery with complete clinical data, showing no significant difference in the primary tumor location ( χ2=0.94, P>0.05), and a significant difference in the tumor diameter ( χ2=17.33, P<0.05) between them. After propensity score matching, the above indicator were 16, 39, 20, 8, 67, 16 in the 83 patients receiving open surgery, versus 15, 46, 17, 5, 67, 16 in the 83 patients receiving laparoscopic surgery, showing no significant difference between them ( χ2=1.54, 0.00, P>0.05). Cases with postoperative complications, cases with grade Ⅰ?Ⅱ complica-tions and ≥grade Ⅲ complications of the Clavien-Dindo classification, duration of postoperative hospital stay, the 5-year overall survival rate and 5-year disease-free survival rate were 17, 12, 5, 11(range, 5?120)days, 92.0%, 100.0% in the 83 patients receiving open surgery, versus 9, 7, 2, 11(range, 5?41)days, 91.6%, 97.3% in the 83 patients receiving laparoscopic surgery, showing no signi-ficant difference in postoperative complications, duration of postoperative hospital stay, the 5-year overall survival rate and 5-year disease-free survival rate ( χ2=2.91, Z=3 365.50, χ2=3.02, 1.49, P>0.05) between them. There was no significant difference in complications of the Clavien-Dindo classification between them ( P>0.05). ④ Comparison of clinical efficacy of patients with primary tumor located at the descending segment of duodenum who underwent surgery with different surgical resection scopes. Before propensity score matching, cases with tumor diameter ≤5 cm and >5 cm, cases with tumor located at opposite side of mesangium and mesangium were 71, 85, 28, 128 in the 156 patients with primary tumor located at the descending segment of duodenum who underwent PD with complete clinical data, versus 92, 41, 120, 13 in the 133 patients with primary tumor located at the descending segment of duodenum who underwent duodenal limited resection with complete clinical data, showing significant differences between them ( χ2=16.34, 150.10, P<0.05). After propensity score matching, the above indicator were 28, 13, 16, 25 in the 41 patients with primary tumor located at the descending segment of duodenum who underwent PD with complete clinical data, versus 28, 13, 16, 25 in the 41 patients with primary tumor located at the descending segment of duodenum who underwent duodenal limited resection with complete clinical data, showing no significant difference between them ( χ2=0.00, 0.00, P>0.05). Cases with postopera-tive complications, cases with grade Ⅰ?Ⅱ complications and ≥grade Ⅲ compli-cations of the Clavien-Dindo classification, duration of postoperative hospital stay, the 5-year overall survival rate and 5-year disease-free survival rate were 13, 11, 2, 15(range, 9?62)days, 94.2%, 64.3% in the 41 patients with primary tumor located at the descending segment of duodenum who underwent PD with complete clinical data, versus 9, 8, 0, 15(range, 7?40)days, 100.0%, 78.8% in the 41 patients with primary tumor located at the descending segment of duodenum who underwent duodenal limited resection with complete clinical data, showing no significant difference in post-operative complica-tions, the 5-year overall survival rate and 5-year disease-free survival rate ( χ2=0.99, 0.34, 1.86, P>0.05) between them. There was no significant difference in complications of the Clavien-Dindo classification ( P>0.05) and there was a significant difference in duration of postopera-tive hospital stay ( Z=614.50, P<0.05) between them. Conclusions:The clinical efficacy of radical surgery for duodenal GIST are ideal. Primary tumor located at the horizontal segment of duodenum, mitotic count >5/50 high power field, tumor gene KIT exon 9 mutation are independent risk factors affec-ting the overall survival of patients undergoing direct radical surgery and tumor diameter >5 cm and mitotic count >5/50 high power field are independent risk factors affecting the disease-free survival of patients. There is no significant difference in the short-term efficacy and long-term prognosis between patients undergoing open surgery and laparoscopic surgery. For patients with primary tumor located at the descending segment of duodenum, the duration of postoperative hospital stay is longer in patients undergoing PD compared with patients undergoing duodenal limited resection. For patients evaluated as high risk of the modified NIH risk classification, posto-perative adjuvant therapy and treatment time ≥36 months are conducive to improving the prognosis of patients.

Objective:To evaluate the efficacy and tolerability of crisaborole 2% ointment in the treatment of childhood atopic dermatitis (AD) at the early stage, and to compare the efficacy of every-other-day (Qod) regimen versus twice-a-week (Biw) regimen against recurrence in the remission stage of AD.Methods:A multicenter, randomized, open-label clinical trial was conducted. Totally, 150 children with mild to moderate AD aged 2 - < 18 years were enrolled from 6 hospitals (including Beijing Children′s Hospital, Capital Medical University, etc), and randomly divided into the Qod group (76 cases) and the Biw group (74 cases). In the acute stage of AD, both groups were treated with topical crisaborole 2% ointment on skin lesions twice a day for 2 - 4 weeks, as well as with emollients throughout the whole body. The improvement of early clinical symptoms was evaluated, and the occurrence of adverse reactions was recorded in the follow up. Once the investigator′s static global assessment (ISGA) scores decreased to 1 point or less, the patient would be enrolled into the remission stage. In the remission stage of AD, patients in the Qod group and Biw group were treated with crisaborole ointment every other day and twice a week respectively; the recurrence rate of AD in the remission stage was evaluated, as well as the severity of skin lesions, itching, life quality, and the occurrence of adverse reactions at weeks 4, 8, and 12. Statistical analysis was carried out with SPSS 23.0 software by using t test for comparisons of normally distributed continuous data between two groups, Mann-Whitney U test for non-normally distributed data, chi-square test for enumeration data, and Kaplan-Meier method for analysis of survival rates. Results:A total of 142 patients were enrolled in the modified intention-to-treat population, including 71 in the Qod group and 71 in the Biw group. In the acute stage of AD, the improvement of itching and skin lesions self-reported by the children or their family members occurred on days 1.9 (1.0, 3.0) and 2.0 (1.0, 4.1) after the application of crisaborole ointment, respectively. At the end of treatment in the acute stage, 89 children (62.7%) achieved ISGA 0/1 and successfully transferred into the remission stage. The follow-up in the remission stage was completed in 83 patients (44 in the Qod group and 39 in the Biw group). In addition, recurrence occurred in 19 (43.2%) and 12 (30.8%) patients in the Qod group and Biw group respectively, and there was no significant difference in the recurrence rate between the two groups ( χ2 = 1.36, P = 0.243) ; the average time to recurrence was 64.25 (95% CI: 53.33 - 75.17) days and 75.78 (95% CI: 65.46 - 86.10) days in the Qod group and Biw group respectively. Among the patients who were in the remission stage and had not yet experienced relapse at weeks 4, 8, and 12, there were no significant differences in the eczema area and severity index (EASI) scores, ISGA scores, pruritus numerical rating scale (NRS) scores, or quality-of-life scores between the two groups (all P > 0.05) at any time points, except for the ISGA scores at week 12 (Biw group: 0 [0, 1] point vs. Qod group: 1 [0, 1] point; Z = -2.31, P = 0.021). A total of 146 patients were enrolled in the safety set. During the study period, 70 adverse events occurred in 65 patients, with an incidence rate of 44.5%, and all were mild or moderate adverse events; 55 (37.7%) patients experienced discomfort at the medication site, which mainly referred to pain (45 cases, 30.8%) and mostly occurred in the tender and skinfold areas. Conclusions:Crisaborole 2% ointment could effectively relieve clinical symptoms in children with mild to moderate AD in the early stage, and intermittent treatment could continuously relieve clinical symptoms in the remission stage. The common adverse reaction was discomfort at the application site in the early stage of AD. There was no significant difference in the impact on AD recurrence in the remission stage between the Qod regimen and Biw regimen.
