ABSTRACT
Objective:To analyze the clinical symptoms and laboratory characteristics of patients with brucellosis combined with osteoarthritis.Methods:A retrospective analysis was conducted on the medical records of 168 patients with brucellosis who were hospitalized at the Jining Public Health Medical Center, Shandong Province from January 2021 to December 2022. Based on the imaging examination results, they were divided into combined osteoarthritis group and non combined osteoarthritis group. The demographic characteristics, clinical symptoms, and laboratory test results of the two groups of patients were compared and analyzed.Results:Among 168 patients with brucellosis, there were 83 patients with concurrent osteoarthritis, 85 patients without concurrent osteoarthritis, the males and females ratio was 2.73 ∶ 1.00 (123 ∶ 45), and the age was 56 (46, 64) years old. The median age of patients in combined osteoarthritis group was higher than that of patients in non combined osteoarthritis group (58 years vs 53 years, Z = - 2.89, P = 0.004). In clinical symptoms, the incidence of back pain, fatigue, and joint muscle pain in patients of combined osteoarthritis group was significantly higher than that in the non combined osteoarthritis group [75.9% (63/83) vs 56.5% (48/85), 30.1% (25/83) vs 15.3% (13/85), 47.0% (39/83) vs 17.6% (15/85), χ 2 = 7.07, 5.27, 16.58, P < 0.05]. In laboratory tests, the erythrocyte sedimentation rate (ESR) and hypersensitive C-reactive protein (hs-CRP) levels in patients of combined osteoarthritis group were higher than those in the non combined osteoarthritis group [27.0 (17.0, 34.0) mm/h vs 21.0 (10.5, 34.0) mm/h, 22.7 (14.3, 43.4) mg/L vs 17.9 (10.8, 34.2) mg/L, Z = - 2.51, - 2.00, P < 0.05]. Among patients with combined osteoarthritis, combined spondylitis accounted for the highest proportion (55.4%, 46/83), followed by peripheral arthritis (51.8%, 43/83). Conclusion:Osteoarthritis is a common complication of brucellosis, and patients of brucellosis with concurrent osteoarthritis have clinical features such as lower back pain, fatigue, and joint muscle pain, with significantly elevated of ESR and hs-CRP level.
ABSTRACT
Objective:Health education program based on information-motivation-behavioral skills model (IMB model) was developed, and its application effect in functional exercise after autogenous arteriovenous fistula (AVF) in hemodialysis patients was explored.Methods:Using the convenient sampling method, 100 patients undergoing AVF surgery in hemodialysis center of Qingdao Municipal Hospital from June 2020 to June 2021 were selected as the study objects. The patients were numbered according to the order of visit. The single number was the observation group, and the double number was the control group. There were 50 patients in each group. The control group was given routine AVF function exercise education, and the observation group was given AVF function exercise education based on the IMB model. Patients′ compliance with functional exercise, cephalic vein diameter, fistula maturation time, and the incidence of complications were compared between the two groups.Results:Finally, 49 cases in the control group and 50 cases in the observation group finished the research. The compliance of function exercise of the observation group was 94.0%(47/50), which was higher than 73.5%(36/49) in the control group, and the difference was statistically significant ( χ2=7.70, P<0.05). The maturation time of plasty in the observation group was (5.18 ± 1.14) weeks, shorter than that in the control group (5.94 ± 1.39) weeks, and the difference was statistically significant ( t=2.98, P<0.05). The cephalic vein diameter and blood flow controlled by hemodialysis pump in the observation group were (5.19 ± 0.28) mm and (218.40 ± 24.19) ml/min, respectively, higher than those in the control group (4.99 ± 0.34) mm and (200.41 ± 23.89) ml/min, the differences were statistically significant ( t=-3.21, -3.72, both P<0.05). The incidence of fistula complications in the observation group was 6.0%(3/50), lower than 22.4%(11/49) in the control group, and the difference was statistically significant ( χ2=5.52, P<0.05). Conclusions:The application of IMB model in hemodialysis patients with functional exercise after AVF plasty can effectively improve patients′ compliance, increase the diameter of cephalic vein and the blood flow controlled by dialysis pump, shorten the maturation time of internal fistula, and reduce the incidence of complications of AVF.

ABSTRACT
Objective To investigate the influences of IL-17 on regulatory T ( Treg) cells during Chlamydia trachomatis infection. Methods Wild-type ( WT) C57BL/6 mice and IL-17-/- mice were in-tranasally injected with 1×103inclusion forming units (IFU) of Chlamydia muridarum (Cm) to establish the mouse model of Chlamydia trachomatis respiratory tract infection. Mouse spleen and lung single cells were prepared. The percentages of CD4+CD25+T and CD4+CD25+Foxp3+T cells were detected by flow cytome-try. Expression of Foxp3 and TGF-β at mRNA level in lung was detected by RT-PCR. The levels of IL-10 in bronchoalveolar lavage fluid samples were detected by ELISA. Results Compared with the WT mice, the IL-17-/- mice had higher percentages of CD4+CD25+T and CD4+CD25+Foxp3+T cells in spleen and lung on the third day of Cm infection. Both of the expression of Foxp3 at mRNA level in lung and the secretion of IL-10 in bronchoalveolar lavage fluid were increased in IL-17-/- mice as compared with those in WT mice. No significant difference in the expression of TGF-β at mRNA level in lung tissues was found between the two groups. Conclusion IL-17 might inhibit the proliferation of Treg cells and the secretion of IL-10 in the very early stage of Cm respiratory tract infection.
ABSTRACT
Objective To analyze the clinical characteristics of patients with presbycusis by using disyllabic mandarin speech test materials (MSTMs).Methods A total of 59 subjects (23 men and 36 women) with presbycusis,from 61 to 84 years old with the average as 71.3±6.7.They were divided into three groups:the mild group (10 subjects),the moderate group (35 subjects)and the severe group (14 subjects)according to the pure tone average (PTA) thresholds at 0.5,1,2 and 4 kHz from the better ear.In addition,11 subjects of elderly persons with normal hearing were used as the control group.All the subjects enrolled in this study could speak Mandarin well in their daily lives.Nine lists of disyllabic mandarin speech test materials were utilized to test speech recognition threshold (SRT) and P-I function for these groups respectively.Results The PTA(51.65±11.98)and SRT (50.98±16.05)from presbycusis group were much higher than the control group(PTA 19.55± 4.55,SRT 18.79± 7.45),while the average slope of the P-I function 2.63%/dB from the presbycusis group was lower than the control group 4.65%/dB (P<0.01).The SRT of male patients (56.54±17.23) was higher than the females(47.99± 15.63) (P<0.05).The PTA and SRT in these three groups divided by degrees of hearing loss were higher than the control group obviously.The PTA and SRT had significantly increased as the degree of hearing loss increased.The differences among these groups were significant (P<0.01).The average slope of P-I function of these three groups divided by degrees of hearing loss (mild group:2.47%/dB,moderate group:2.76%/dB,severe group:2.42%/dB) was smaller than the slopes in the control group which was 4.65 %/dB (P<0.01).The average slope of P-I function among these groups had no significant difference (P>0.05).Conclusion The SRT of patients with presbycusis increased and the SRT of male was higher than the females.The average slope of P-I function decreased and the curve moved to right side and became a gradual curve.As hearing loss became more severe,the SRT rose more apparently.
ABSTRACT
Objective:To investigate the effect of IL-17A on the differentiation and maturation of murine bone marrow-derived dendritic cells( BMDCs ) . Methods: Murine bone marrow cells were isolated and cultured in RPMI1640 complete medium in the presence of GM-CSF(20 ng/ml) for 8 days to induce differentiation of murine bone marrow cells to DC progenitors. Then these cells were treated with LPS(1 μg/ml) for 36 h which polarized immature DCs into mature DCs. Different concentrations of rmIL-17A(10 or 100 ng/ml) was added to the culture medium at different stages of BMDC differentiation and maturation. Co-stimulatory molecules expression on BMDC were analyzed by flow cytometry,and the culture supernatants were analyzed for IL-12p40 and IL-10 level by ELISA. Results:rmIL-17 could promote co-stimulatory molecules( CD40,CD80,CD86 and MHCⅡ) expression on BMDCs in a does-dependent manner,especially,the expression of CD40 and MHCⅡhad a significant increase in high concentration of rmIL-17A group;rmIL-17A was added while LPS induced maturation of BMDCs. CD40,CD80,CD86 and MHCⅡexpression on BMDC increased sharply in LPS plus rmIL-17A stimulation group,besides,CD86,MHCⅡ showed a higher level expression on BMDC with the increase of con-centration of rmIL-17A. Furthermore,secretion of IL-12p40 and IL-10 increased significantly in the group of DCs treated with LPS plus low concentration of rmIL-17 compared with the group without rmIL-17(P<0. 001). However,high concentration of rmIL-17A group showed significantly higher levels of IL-12p40(P<0. 001),but there was no difference in IL-10. Conclusion:IL-17A promotes the phe-notypic development of BMDC progenitors propagated in GM-CSF and cooperate with LPS to induce BMDC differentiation and matura-tion.

ABSTRACT
This study was aimed to establish an analysis method of amentotaxus biflavone distribution in rats' tissues, including the heart, liver, spleen, lungs, kidney, brain, stomach, large intestine and small intestine, in order to investigate its distribution characteristics in tissues after rats gavaged with amentotaxus biflavone. HPLC-UV was employed to determine contents of amentotaxus biflavone in rats' tissues. The intragastric administration dose of amentotaxus biflavone was 500 mg·kg-1. Rats were sacrificed by cervical dislocation 10 min, 0.5, 1, 2, 4, 8, 12 h after intragastric administration. Tissues of the heart, liver, spleen, lungs, kidney, stomach, large intestine, small intestine and brain were removed and dissected immediately. Distribution of amentotaxus biflavone in each tissue was determined after processing. The results showed that tissue in different range had a good linear range. The lowest detection limit was 0.125 ng. The RSD of intra and inter-day was less than 10%. The absolute recovery rate of amentotaxus biflavone in each tissue was between 75.07% and 89.80%. The relative recovery rate was between 92.00% and 107.00%. Amentotaxus biflavone in each tissue was stable in different tissues in refrigerator of -20° C for 15 days. It was concluded that there were relatively large concentration differences of amentotaxus biflavone in different tissues. After intragastric administration, amentotaxus biflavone was mainly distributed in the stomach, large intestine, small intestine, liver and kidney, and then the heart, lungs and spleen. It also distributed in brain tissues through the blood-brain barrier.
