OBJECTIVE:To explore the repairing effect and mechanism of Huazhuo jiedu yukui formula on the mucosal dam-age of rats with ulcerative colitis (UC). METHODS:72 rats were randomly divided into blank group,model group,mesalamine group(positive control,0.3 g/kg),Huazhuo jiedu yukui formula low-dose,medium-dose,high-dose groups(5,10,20 g/kg),12 in each group. Except for blank group,other groups were induced UC model. After 4 d of modeling,rats in administration groups received related medicines,ig,blank group and model group received normal saline,ig,once a day,for 2 weeks. After administra-tion,disease activity index(DAI)and mucosal damage index(CMDI)of rats were observed;IL-8,TNF-α contents in serum and cyclooxygenase 2 (COX-2) expression in colon tissue were detected. RESULTS:Compared with blank group,DAI and CMDI scores in model group were increased;IL-8,TNF-α contents in serum were increased;COX-2 expression in colon tissue was en-hanced,with statistical significances (P<0.05). Compared with model group,DAI and CMDI scores in model group were de-creased;IL-8,TNF-α contents in serum were reduced;COX-2 expression in colon tissue was weakened,with statistical signifi-cances (P<0.05). Compared with mesalamine group, the above-mentioned indicators in Huazhuo jiedu yukui formula medi-um-dose,high-dose groups changed more obviously (P<0.05),and effects of Huazhuo jiedu yukui formula showed significant dose-effect relationship. CONCLUSIONS:Huazhuo jiedu yukui formula can improve disease activity status of UC rats and reduce colon mucosal damage,and the effects of medium-dose and high-dose Huazhuo jiedu yukui formula were better than mesalamine, which may be related to reducing inflammatory reaction and inhibiting COX-2 expression in colon tissue.

OBJECTIVE: To analysis the characteristics of sudden sensorineural hearing loss (SSHL) patients with tinnitus, and explore the relationship of characteristics of tinnitus and audiology. METHOD: Patients diagnosed as SSHL with tinnitus were studied in the research. All patients' clinical features were analyzed, such as tinnitus frequency, pure tone audiometry, tinnitus, hearing loss degree, results of residual inhibition test. RESULT: Thirty cases were identified as mild degree hearing loss, 13 cases as moderate degree, 28 cases as severe degree and 34 cases as profound degree. And hearing impaired frequency of 13 cases was ascertained at low-frequency, 39 cases at middle-high-frequency, and 53 cases at full-range-frequency. The incidence of patients with low-frequency was about 41. 9% (44/105), and it was about 21. 9% (23/105) in those with middle-frequency. And it was 36. 2% (38/105) in cases of high-frequency tinnitus. The chi-square test show statistically significant differences between patients with the low-frequency, middle-frequency and high-frequency of the hearing loss (P<0. 05). In tinnitus residual inhibition test, positive rate of convergence type masking curve was about 72.0%, tinnitus separated type masking curve 20.0%, overlapping type was 57.9%, and the spacing type was 43.5%. There was a statistically significant difference among cases with different type masking curve (P<0. 05)with the spacing residual inhibition test positive rate. CONCLUSION There are individual differences of clinical characteristics among SSHL patients with tinnitus. Tinnitus frequency is consistent with the frequency of hearing loss. Patients had the more serious the degree of hearing loss, who had more serious tinnitus grading. Cases with the converged type curve will be fit for tinnitus masking. Therefore, combining the tinnitus detection with the audiological tests, we could obtain the clinical characteristics of SSHL patients with tinnitus.

Objective:To analyze the independent risk factors for the occurrence of post-traumatic cognitive dysfunction, construct a prediction model for the risk factors of post-traumatic cognitive dysfunction, and verify the effectiveness of the risk prediction model, so as to provide a clinical tool for early prediction of the risk of post-traumatic cognitive impairment.Methods:Part I: patients with brain trauma (training set with 556 subjects) who were hospitalized in 21 tertiary and secondary hospitals from Tangshan, Cangzhou and Chengde cities of Hebei province were retrospectively collected from February to May 2021 for Montreal cognitive assessment, and 33 influencing factors (general data, symptoms and signs, laboratory and imaging parameters) were obtained obtained through literature research.The patients were divided into case group and control group according to whether they had cognitive impairment or not, and univariate and multivariate analysis were used to screen independent risk factors.Part Ⅱ: a binary Logistic regression equation was used to construct a cognitive impairment prediction model, the visualization model of line graph is presented.Part Ⅲ: brain trauma patients (260 subjects of the validation set) hospitalized in the aforementioned 21 hospitals from August to October 2021 were collected as a prospective validation population for the prediction model of cognitive impairment, and the grouping basis of case group and control group was the same as before.And the risk factors between the two groups were compared.The receiver operating characteristic curve(ROC), calibration curve and clinical applicability of the model were drawn to evaluate the effectiveness of the model for internal and external verification of the model.Results:Binary Logistic regression analysis showed that the risk factors for post-traumatic cognitive dysfunction were basal ganglia injury, severe injury, amnesia experience after injury, frequent headache after injury, upper limb dysfunction after injury, age ≥ 60 years, and education level of elementary school or below.Visual nomograms showed that the experience of amnesia after injury, frequent headache after injury, upper limb dysfunction, and degree of injury among the symptom factors were the factors that contributed greatly to the risk of traumatic brain injury cognitive impairment in this model.Predictive model discrimination using area under curve(AUC) values of the area under the ROC curve showed that internal validation and external validation were 0.868 and 0.885 for R language analysis and 0.868 and 0.901 for SPSS analysis, respectively.The curve after model calibration almost coincided with the reference line, Hosmer-Lemeshow test P>0.05.The two decision curve analysis (DCA) curves drawn by the clinical applicability of the model were higher than the two extreme curves, predicting that traumatic brain injury patients with cognitive impairment could benefit from the predictive model, and there was a net benefit rate in the range of Pt about 0.1-0.8, when Pt reached about 0.1 until the approximate 1.0 composite evaluation model. Conclusion:Risk factors such as experience of amnesia after injury, frequent headache after injury, upper limb dysfunction, and degree of injury are predicting factors contributed to the risk of cognitive impairment in traumatic brain injury, and their prediction models have good predictive effect, high predictive accuracy and good clinical applicability, which can be applied in clinical diagnosis.

Objective:To discuss the effect of remnant cholesterol (RC) levels on carotid intima thickness (CIT) in patients with type 2 diabetes mellitus (T2DM) by ultra-high frequency ultrasound.Methods:A total of 60 patients with T2DM who received treatment in Henan Provincial People′s Hospital from May 2021 to July 2022 were prospectively recruited, and they were divided into a higher RC group (31 cases) and a lower RC group (29 cases) according to the RC levels. Thirty-one age, sex and body mass index(BMI)-matched healthy volunteers were selected as control group. Carotid CIT, carotid media thickness(CMT) and intima-media thickness(CIMT) were measured by 24 MHz ultra-high frequency ultrasound probe. The difference of general clinical data, laboratory indicators and CIMT, CIT, CMT among the three groups were compared, and the influencing factors of CIT in T2DM patients were explored by multivariate regression analysis.Results:①There were no statistical significances in gender, age, BMI, high-density lipoprotein cholesterol (HDL-C) and CMT among the three groups (all P>0.05). There were no statistical significances in duration of diabetes, fasting blood-glucose and glycated haemoglobin between the two subgroups of T2DM (all P>0.05). ②Compared with the control group, CIMT and CIT were thicker in the T2DM group (both P<0.05). ③CIT was thicker in the higher RC group than in the lower RC group ( P<0.05), while the difference of CIMT was not statistically significant the two groups ( P>0.05). ④Multivariate regression analysis showed that RC was the influence factor of CIT in patients with T2DM(β=0.610, P=0.005). Conclusions:CIT is significantly thicker in T2DM patients with higher RC than in those with lower RC, and RC is the influence factor of CIT, which suggests that more attention should be paid to the detection of RC in T2DM patients.

OBJECTIVE: To study the clinical and sequence character of the entire mitochondrial genome in five subjects with mitochondrial 12SrRNA T1095C mutation, and to analyze its relationship with the military noise-induced hearing loss (NIHL). METHOD: Three hundreds and four soldiers exposed to military noise were selected in Yunan and Beijing, including susceptible (experimental) and tolerance (control) groups. Mitochondrial 12SrRNA T1095C mutation were found in 5 subjects. Then the complete nucleotide sequence of five subjects were sequenced and its clinical character were analyzed. RESULT: m12SrRNA T1095C mutation were identified in 5 subjects of experimental group,and none were found in control group. There was significant difference between them (P < 0.05). All five soldiers had the history of military noise exposure and showed sensorineural deafness of different degrees. Sequence analysis of the complete mitochondrial genomes showed the distinct sets of mtDNA polymorphism besides T1095C mutation in five subjects. CONCLUSION The T1095C mutation in hearing loss subjects with various genetic background and history of military noise exposure, is involved in the pathogenesis of hearing impairment. It indicates that the T1095C mutation do relate well with military noise induced-hearing loss.

Objective:To evaluate the carotid artery elasticity in the first-degree relatives of patients with type 2 diabetes mellitus.Methods:Ninety first-degree relatives of patients with type 2 diabetes who received treatment in the Department of Endocrinology of Henan Provincial People′s Hospital from October 2020 to June 2021 were randomly selected and designated as having a positive family history. Depending on the parental history of diabetes they were divided into three groups: 31 cases of family history positive in father (F), 31 cases of family history positive in mother (M) and 28 cases of family history positive in both father and mother (B). Thirty cases with matched age, height and weight without any history of diabetes, hypertension, hyperlipidemia and coronary atherosclerotic heart disease in their parents designated as control group were taken for comparison. Real-time intima-media thickness (RIMT) and R-VQS were employed to evaluate common carotid intima-media thickness (IMT), distance (Dist), diameter (Diam), hardness coefficient (HC) and pulse wave velocity (PWV). The differences among the groups were compared.Results:①There was no statistical significance in Diam among the four groups ( P>0.05). ②Compared with the control group, the IMT, PWV and HC in subjects with positive family history were increased, while Dist was decreased ( P<0.05). ③Paired comparison of the subjects with positive family history: the IMT, PWV and HC in B group were higher than in F and M group, and Dist was lower than in F and M group ( P<0.05). The PWV and HC in M group were higher than in F group, and Dist was lower than in F group ( P<0.05). There was no statistical significance in IMT between the F and M groups ( P>0.05). Conclusions:Carotid artery stiffness in the cases with positive family history is significantly higher than the control group. The decrease of carotid elasticity in B group is the most serious, M group takes the second place, while the F group is the least.
