OBJECTIVE To investigate the mechanism of Shenling baizhu san （SLBZS） in ameliorating ulcerative colitis （UC）. METHODS Mice were randomly divided into normal group， model group， and low-， medium-， high-dose SLBZS groups （3， 6， 12 g/kg）， with 10 mice in each group. Except for the normal group， mice in other groups were given free access to 3% dextran sulfate sodium solution for 7 days to establish UC models. Simultaneously， mice in each group were intragastrically administered corresponding medicinal liquid or double-distilled water once a day for consecutive 7 days. After the last administration， the histopathological morphology of colon tissues was observed； the serum levels of inflammatory factors including tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β） and IL-18 were detected； the total bile acid contents in liver， gallbladder and colon tissues were determined； the expression level of NOD-like receptor family pyrin domain-containing protein 3 （NLRP3） in colon tissues was tested. The expression levels of flora metabolism-related proteins [G protein-coupled receptor 41（GPR41），GPR43，farnesoid X receptor （FXR）， G protein-coupled bile acid receptor 1 （TGR5）， flavin-containing monooxygenase 3 （FMO3）， cytochrome P450 family 27 subfamily A member 1 （CYP27A1）， CYP7A1] in liver or colon tissues， as well as the proteins related to Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB）/NLRP3 inflammatory axis [TLR4， NF-κB， phosphorylated NF-κB （p-NF-κB）， myeloid differentiation factor 88 （MyD88）， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， caspase-1] in colon tissues were measured. RESULTS Compared with the model group， the colon tissue injury and inflammatory cell infiltration were alleviated in medium- and high-dose SLBZS groups. The serum levels of TNF-α， IL-1β and IL-18， total bile acid contents in liver and colon tissues， as well as the protein expression levels of FMO3 and CYP7A1 in liver tissues， TLR4， p-NF-κB， NF-κB， MyD88， NLRP3， ASC and caspase-1 in colon tissues were significantly decreased （P＜0.05）. Meanwhile， the total bile acid content in gallbladder， the protein expression levels of GPR41 and GPR43 in colon tissues， along with CYP27A1， FXR and TGR5 in liver tissues were significantly increased （P＜0.05）. CONCLUSIONS SLBZS may relieve colonic inflammatory injury and ameliorate UC by regulating the expression of flora metabolism-related proteins and inhibiting the abnormal activation of TLR4/NF-κB/NLRP3 inflammatory axis.

Objective:To explore the current situation and influencing factors of anxiety before early orthodontic treatment for malocclusion in school-age children.Methods:Convenience sampling was used to select 124 school-aged children who underwent early orthodontic treatment for malocclusion at the Hospital of Stomatology, Wenzhou Medical University from October 2023 to October 2024 as study subjects. The Chinese Version of the Modified Yale Preoperative Anxiety Scale (Cm-YPAS) was used to assess pre-treatment anxiety in pediatric patients, while the Self-Rating Anxiety Scale was employed to evaluate parental anxiety, and patient general information was collected. Logistic regression analysis was employed to investigate factors influencing anxiety before early orthodontic treatment in school-age children.Results:The Cm-YPAS scores for 124 school-aged children undergoing early orthodontic treatment were (45.76±7.42), with a pre-treatment anxiety incidence of 54.84% (68/124). Logistic regression analysis showed that age, oral treatment experience, educational background, and parental anxiety score were the influencing factors of anxiety before early orthodontic treatment in school-age children ( P<0.05) . Conclusions:The incidence of pre-treatment anxiety is relatively high among school-age children undergoing early orthodontic treatment. Appropriate nursing interventions should be implemented based on influencing factors to alleviate the pre-treatment anxiety of children.

Objective:To investigate the efficacy of Shuotong ureteroscope combined with flexible ureteroscope in the treatment of 2-3 cm lower calyceal calculi, and analyze the influencing factors.Methods:A total of 102 patients with lower calyceal calculi were treated in the Second People′s Hospital of Yulin from February 2019 to December 2022, and they were divided into the observation group and the control group, with 51 cases in each group. The patients of the observation group were treated with Shuotong ureteroscope combined with flexible ureteroscope, while the patients of the control group were treated with flexible ureteroscope. According to whether the stones were completely removed after operation, all patients were divided into non-stone removal group ( n=13) and stone removal group ( n=89). The operation time, hospitalization time, lithotripsy time, intraoperative blood loss, complication rate and stone clearance rate were compared between the observation group and the control group. Generalized Estimation Equation was used to analyze and evaluate the effects of treatment time, treatment scheme and their interaction on visual analogue scale (VAS), white blood cell (WBC), blood urea nitrogen (BUN), blood creatinine (Cr), hemoglobin (HGB) and procalcitonin (PCT). Univariate and multivariate Logistic regression were used to analyze the risk factors of stone removal rate. Nomogram model was constructed based on risk factors and evaluate the model. Results:Compared with the control group, operation time [(118.72±9.61) min vs (136.65±11.27) min], hospitalization stay [(6.43±1.12) d vs (10.29±2.23) d] and the lithotripsy time [ (51.23±10.38) min vs (56.62±11.43) min] of the observation group were shorter, and the amount of intraoperative blood loss [(128.52±10.20) mL vs (157.53±15.31) mL] were significantly less than those of the control group ( P< 0.05). The results of Generalized Estimation Equation analysis showed that treatment time, treatment regimen and their interaction had significant effects on WBC, HGB, BUN, Cr, PCT and VAS ( P< 0.05). Compared with the control group, the incidence of complications (5.88% vs 19.61%) of the observation group was lower and the stone clearance rate ( 94.12% vs 80.39%) was significantly higher than those in the control group ( P< 0.05). The mode of operation, infundibulopelvic angle(IPA), caliceal pelvic height (CPH) and the maximum diameter of stones were all influencing factors of stone removal rate in patients with 2-3 cm lower calyceal calculi. The nomogram model constructed in this study has good differentiation, calibration and clinical practicability, and can better identify high-risk patients with incomplete removal of 2-3 cm lower calyceal calculi. Conclusions:Shuotong ureteroscope combined with flexible ureteroscope is a safe, effective method for the treatment of 2-3 cm lower calyceal calculi. It has the advantages of simple operation, less intraoperative bleeding, less postoperative complications and high stone clearance rate. IPA, CPH, the maximum diameter of calculi and the mode of operation were all independent factors affecting the stone clearance rate of 2-3 cm lower calyceal calculi. The nomogram model constructed in this study can well identify the high-risk patients with incomplete clearance of 2-3 cm lower calyceal calculi.

Objective:To evaluate the influence of manual digitorum sensory stimulation (MDSS) of hemiplegic fingers in median nerve F-wave in stroke patients.Methods:Thirty patients with hemiplegia after stroke, admitted to Department of Rehabilitation Medicine, Second Affiliated Hospital of Anhui Medical University from June 2019 to October 2022 were selected; all patients had thumb flexor modified Ashworth scale (MAS) grading≥1. Hemiplegic MDSS was given; bilateral median nerve F-wave before MDSS and median nerve F-wave at the hemiplegic side immediately after MDSS were recorded.Results:Compared with that at the healthy side before MDSS, amplitude of median nerve F-wave at the hemiplegic side was significantly increased ( P<0.05). Compared with that before MDSS, amplitude of F-wave at the hemiplegic side after MDSS in patients with thumb flexor MAS grading≤2 were significantly decreased ( P<0.05), while that in patients with thumb flexor MAS grading≥3 was significantly increased ( P<0.05). Conclusion:Amplitudes of median nerve F-wave at the hemiplegic side in patients with different thumb flexor MAS grading show that MDSS can not only inhibit the excitability of tonic motor unit related to muscle spasm, but also enhance the excitability of kinetic-motor unit mainly related to explosive power in severe muscle spasm.

Objective To demonstrate the changes in flexor digitorum and extensor digitorum tension in the affected hands with shear-wave elastography (SWE) before and after manual digitorum sensory stimulation (MDSS) in hemiplegic patients with stroke. Methods A total of 51 hemiplegic post-stroke inpatients in the Department of Rehabilitation Medicine in Second Hospital of Anhui Medical University from April to June, 2020, underwent MDSS completed by a researcher who used a bare thumb and index finger to squeeze each nail bed as well as the sides of each fingertip in the affected hand. The stimulation intensity was the minimum that could cause finger extension without obvious pain, and the interval between two stimulations was five to ten seconds. Muscular tension of the flexor digitorum superficialis, flexor digitorum profundus, flexor pollicis longus and extensor digitorum were assessed with modified Ashworth Scale (MAS) and shear-wave velocity (SWV) of SWE on the affected side before and immediately after MDSS. MAS score was -1 as low muscular tension. Results The MAS scores of all the muscles significantly reduced after MDSS (|Z| > 2.843, P < 0.001); while the changes of SWV were not significantly in all the muscles with initially MAS score of 0 or -1 (t < 1.052, P > 0.05), and it reduced in those muscles with initial MAS scores of one to three (t > 2.672, P < 0.05). The SWV were positively correlated with the MAS scores both before and after MDSS (r > 0.334, P < 0.05). Conclusion MDSS can effectively, immediately, and safely relieves muscle spasms of the flexor digitorum and facilitate active finger extension in the affected hand for hemiplegic patients with stroke. SWE is useful for quantitatively and objectively evaluating muscular tension in the affected hand for hemiplegic patients with stroke.
