Objective To explore the effect of Qingre Xiaoyanning tablets on chronic toxicity in SD rats.Methods A total of 120 SD rats were randomly divided into blank group(water)and experimental-L,-M,-H groups(2.63,5.25 and 10.50 g·kg 1 Qingre Xiaoyanning dry paste powder),with 30 rats per group.Four groups were administered continuously for 4 weeks with a recovery period of 4 weeks.SD rats were dissected as planned.The general condition,weight gain,hematological and biochemical indexes,major organ coefficients,macroscopic and microscopic tissue morphology were observed.Results There were no significant differences in the general condition,body mass growth,coagulation index and histopathology of rats between the experimental-L,-M,-H groups and the blank group.End of administration,the mean hemoglobin concentrations of experimental-H and blank groups were(370.70±3.78)and(365.90±5.77)g·L-1,glucose were(5.98±0.63)and(6.61±0.93)mmol·L-1,blood urea nitrogen(BUN)were(4.72±1.01)and(5.78±1.64)mmol·L-1,liver coefficients were 3.05±0.17 and 2.89±0.19,and the differences were statistically significant(P≤0.05,P≤0.01).Resumption of the final,direct bilirubin of experimental-L and blank groups were(0.38±0.18)and(0.19±0.18)pmol·L 1,BUN of experimental-M and blank groups were(4.45±0.56)and(5.65±1.16)mmol·L-1,and the differences were statistically significant(all P≤0.05).Conclusion Repeated administration of Qingre Xiaoyanning tablets showed no significant toxicity in SD rats.

Objective:To evaluate auditory spatial discrimination capabilities in patients with mild to moderately severe symmetrical sensorineural hearing loss (SNHL) and to compare the impact of different psychophysical testing methods on Minimum Audible Angle (MAA) and test duration.Methods:A total of 105 symmetrical SNHL patients aged from 18 to 60 years old were enrolled from April to July 2023, including 56 males and 49 females. They were divided into three groups based on PTA: mild, moderate, and moderately severe hearing loss, with 35 individuals in each group. Additionally, a control group of 35 individuals with normal hearing was tested, including 18 males and 17 females. Participants underwent four distinct psychophysical discrimination tests: the block up-down, 1-up/1-down, 1-up/2-down, and 1-up/3-down procedures. We recorded the MAA and test duration for each. We employed repeated measures of ANOVA to compare the MAA and test duration across different methods and groups, and Pearson′s correlation to assess the relationship between MAA and degree of hearing loss.Results:MAA of sound localization in patients with symmetrical SNHL was significantly positively correlated with the degree of hearing loss ( r=0.59, P<0.01). Significant deterioration in MAA was observed as hearing loss progressed to the moderate level (PTA≥35 dBHL, P<0.01). The testing methods significantly influenced MAA and testing duration ( F=24.02, P<0.01; F=75.56, P<0.01) and the 1-up/1-down method was the quickest, averaging only (0.69±0.32) mins. Conclusions:The horizontal plane auditory spatial discrimination abilities in patients with symmetrical SNHL is impaired progressively with increasing hearing loss, notably beyond moderate hearing loss levels. Different psychophysical methods influence both MAA and test duration, the quicker 1-up/1-down method is recommended for assessing MAA in symmetrical SNHL patients.

Objective To evaluate the effects of 3-indoleacetic acid(IPA)on epithelial-mesenchymal transition(EMT)and fi-brosis in mice peritoneal mesoepithelial cells stimulated by lipopolysaccharide.Methods Mouse peritoneal mesothelial cells be-fore and after LPS treatment were interfered with IPA at different concentrations(0.1,1.0 and 10 μmol/L),and the cell prolif-eration activity was examined by CCK-8 method to determine the optimal dose of IPA.Mice peritoneal mesothelium cells were divided into Control group,LPS group,LPS+IPA group,LPS+LY364947(TGF-β1 receptor inhibitor)group,LPS+IPA+LY364947 group and LPS+IPA+SRI-011381(TGF-β1 pathway activator)group.Cell proliferation viability was evaluated by CCK-8 assay and cell invasion was detected by Transwell assay.EMT-related factor(E-cadherin)and TGF-β1/Smad3 pathway-related factor(Smad3,p-Smad3)protein expression in cell supernatant was evaluated by Western blotting,and mesenchymal phe-notype α-smooth muscle actin(α-SMA)protein content was detected by ELISA.Results The optimal dose of IPA was 1.0μmol/L.Compared with Control group,cell proliferation and E-cadherin expression level were decreased(all P＜0.01).Invasivi-ty,α-SMA expression and p-Smad3/Smad3 were increased in LPS group(all P＜0.01).Compared with LPS group,cell prolifer-ative activity and E-cadherin expression level were increased(all P＜0.01),and invasivity,α-SM A expression and p-Smad3/Smad3 were decreased in LPS+IPA and LPS+LY364947 groups(all P＜0.01).Compared with LPS+IPA group,LPS+IPA+LY364947 group showed a more significant trend.The trends of measured indexes were reversed after SRI-011381 treatment in LPS+IPA group.Conclusion IPA inhibits Smad3 phosphorylation,thereby inhibiting cell EMT progression and alleviating LPS-induced peritoneal mesothelial cell injury.

Objective To conduct a detailed clinical phenotypic analysis and gene mutation detection on an au-tosomal dominant Van der Hoeve syndrome family,and to identify the pathogenic gene mutation sites of the family and the impact of the mutation on gene coding.Methods Clinical data including medical history,physical examina-tion and auxiliary examination were collected and peripheral blood samples were collected from the Van der Hoeve syndrome families.Exome sequencing and Sanger sequencing were performed on 22 family members.The data were analyzed using bioinformatics software.Results The family had a total of 5 generations,with each generation expe-riencing consecutive illnesses.Each generation of men and women could suffer from the disease,which conformed to the characteristics of autosomal dominant inheritance.The 12 patients in this family were all born with blue sclera and short stature.8 patients had a history of fractures and could heal normally.3 patients were considering hearing loss caused by Van der Hoeve syndrome.12 patients had a base deletion(c.1128delT)in exon 17 of the COL1A1 gene,causing a change in the amino acid coding after position 376 and ending the amino acid coding prematurely at position 539.10 asymptomatic individuals in this family didn't had this mutation.Conclusion The patient of this family was identified as Van der Hoeve syndrome caused by c.1128 delT mutation.

Objective To observe the clinical efficacy and safety of traditional Chinese medicine(TCM)constitution correction based on the theory of preventive treatment of disease on the patients with early asymptomatic diabetic peripheral neuropathy(DPN).Methods A total of 87 patients with early asymptomatic DPN were randomly divided into the control group with 43 cases and the trial group with 44 cases.The control group was required to have standard diet,do exercises and take medicines for diabetes.On the basis of treatment for the control group,the trial group was given the corresponding TCM constitution correction regimen according to the predominated constitution types of the patients.The course of treatment for the two groups lasted for 48 weeks.Before and after intervention,the two groups were observed in the alteration of TCM constitution types,and the changes of body mass index(BMI),systolic blood pressure(SBP),diastolic blood pressure(DBP),fasting plasma glucose(FPG),glycosylated hemoglobin(HbA1c),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C)and nerve conduction velocity(NCV).Moreover,the safety of the two groups was evaluated.Results(1)After the intervention,the constitution of 17 patients in the trial group was transformed into the balanced constitution,while only the constitution of 5 patients in the control group was transformed into balanced constitution.There was a statistically significant difference in the distribution of TCM constitution between the two groups(P＜0.05).(2)Before intervention,there were no significant differences in the levels of BMI,SBP,DBP,FPG,HbA1c,TC,TG,HDL-C and LDL-C between the two groups(P＞0.05).After intervention,the levels of BMI,SBP and DBP in the two groups and the levels of HbA1c,TC,TG and LDL-C in the trial group were lower than those before intervention(P＜0.05 or P＜0.01),while the levels of FPG and HDL-C in the control group were higher than those before intervention(P＜0.05 or P＜0.01).The intergroup comparison showed that the levels of FPG,HbA1c,TG and LDL-C in the trial group were significantly lower than those in the control group(P＜0.05 or P＜0.01).(3)After the intervention,10 cases in the control group had typical clinical symptoms of DPN,while only 6 cases in the trial group had the clinical symptoms of DPN.Before intervention,there was no significant difference in the motor nerve conduction velocity(MNCV)of bilateral tibial nerve and common peroneal nerve and in the sensory nerve conduction velocity(SNCV)of bilateral sural nerve and superficial peroneal nerve between the two groups(P＞0.05).After intervention,the MNCV of bilateral tibial nerve and common peroneal nerve and the SNCV of bilateral sural nerve and superficial peroneal nerve in the control group were slower than those before intervention(P＜0.05),while the above indicators of nerve conduction velocity in the trial group were mildly increased compared with those before intervention,but the differences were not significant(P＞0.05).The intergroup comparison showed that the MNCV of bilateral tibial nerve and SNCV of bilateral sural nerve and superficial peroneal nerve in the trial group were higher than those in the control group,and the differences were statistically significant(P＜0.05).(4)During the intervention,no obvious adverse reactions occurred in the two groups,with high safety.Conclusion The TCM constitution correction can adjust the biased constitution of patients with early asymptomatic DPN,and has certain protective effect on the glucose and lipid metabolism,MNCV of tibial nerve,and SNCV of bilateral sural nerve and superficial peroneal nerve.

Objective To explore the clinical efficacy and safety of one-stage posterior lesion removal and internal spinal fixation in patients with lumbar Brucellosis spondylitis.Methods The clinical data of 24 patients admitted from October 2017 to October 2022 were retrospectively analyzed,2 patients were lost to follow-up at 10 months after surgery,at the final 22 cases were included in the study,including 13 males and 9 females with an average age of(52.00±6.89)years old,were treated with one-stage posterior lesion removal and internal spinal fixation.The operation time,intraoperative bleeding,follow-up time,ery-throcyte sedimentation rate(ESR)and C-reactive protein(CRP)before and after operation were recorded.The pain visual ana-logue scale(VAS),Oswestry disability index(ODI),the Japanese Orthopaedic Association(JOA)score for neurofunction,American Spinal Injury Association(ASIA)spinal cord injury grade and modified MacNab criteria were ussed to evaluate the efficacy.Results All patients were followed up from 12 to 30 months with an average of(17.41±4.45)months.The operation time was 70 to 155 min with an average of(1 16.59±24.32)min;the intraoperative bleeding volume was 120 to 520 ml with an average of(275.00±97.53)ml.CRP and ESR levels decreased more significantly at 1 week and at the final follow-up than pre-operative levels(P＜0.05).VAS,JOA score and ODI at 1 week and at the latest follow-up were more significantly improved than preoperative results(P＜0.05).There was no significant difference between ASIA preoperative and 1 week after operation(P＞0.05),and a significant difference between preoperative and last follow-up(P＜0.05).In the final follow-up,21 patients had ex-cellent efficacy,1 patient had fair,and there was no recurrence during the follow-up.Conclusion One-stage transpedicular le-sion removal and internal spinal fixation,with few incisions and short operation time,helps the recovery of neurological func-tion,and the prognosis meets the clinical requirements,which can effectively control Brucella spondylitis.
