OBJECTIVE: To evaluate the efficacy of sublingual immunotherapy (SLIT) with Dermatophagoides farinae drops for allergic rhinitis (AR) of different symptom severity. METHOD: This retrospective analysis to receive SLIT treatment of 143 cases of patients with allergic rhinitis, according to the severity of disease symptoms divid- ed into two groups, moderate group (62 patients) and severe group (81 patients). Before SLIT and after SLIT for half year, 1 year and 1. 5-2.0 years, the TNSS, TMS and sign scores of patients with allergic rhinitis were evaluated. RESULT: The TNSS, TMS and sign scores had continuously improved significantly after SLIT for half year, 1 year and 1.5-2.0 years in two groups as compared with baseline (P < 0.05). Before SLIT, TNSS and sign scores of severe group had a significantly higher level than moderate group (Z = 10.40, 2.40, P < 0.05), while TMS of two groups had no significant differences (Z = 0.00, P > 0.05). Half year after SLIT treatment, in two groups for sign scores, there were significant differences (Z = 3.32, P < 0.05), and there were no significant differences for TNSS (Z = 1.58, P > 0.05) and TMS (Z = 0.37, P > 0.05). 1 and 1.5-2.0 years after SLIT, there were no significant differences in two groups for TNSS, TMS and sign scores (P > 0.05). CONCLUSION SLIT with Dermatophagoides farinae drops for 1.5-2.0 years is effective in the patients with allergic rhinitis of different symptom severity. And equivalent efficacy could be achieved for different symptom severity.

Objective To explore the differences in the static balance ability of elderly women performing Tai Chi, square dance, and fitness walking as long-term exercises. Methods A total of 128 healthy elderly women were selected as the subjects. The subjects were classified into the Tai Chi, square dance, fitness walking, and control groups based on their daily main fitness items. The average swing speed (avg.v) of the subjects, swing angle, outer area (area), and total length of the swing (TL) were measured by a balance tester during double-feet standing with eyes closed and right-foot standing with eyes opened, and the test time was 10 s. Results There were significant differences in the values of each balance index of the Tai Chi, square dance, fitness walking, and control groups during double-feet standing with eyes closed and right-foot standing with eyes opened(P<0.05). There were significant differences in the avg.v, TL, and area index values of the Tai Chi and square dance groups (P<0.05) in case of right-foot standing with eyes opened. In both the states,the four balance indices of the Tai Chi group were significantly smaller than those of the fitness walking group (P<0.05).There were significant differences in the area, TL, and avg.v index values of the square dance and fitness walking groups (P<0.05) for the right-foot standing with eyes opened. Conclusions The static balance abilities of elderly women performing Tai Chi, square dance, and fitness walking over a long term were better than those in the absence of regular exercises. The elderly women associated with long-term Tai Chi exercises exhibited a better static balance ability than those performing square dance and fitness walking exercises, and elderly women associated with long-term square dance exercises showed a better static balance ability than those with fitness walking exercises.

Objective To construct an early warning model of fall risk for the elderly based on six kinds gait parameters. Methods A digital field was used to collect parameters from six kinds of gait for the elderly with or without the history of falls, and the binomial logistic regression analysis was used to establish a regression equation for predicting the fall risks in the elderly, and an early warning model was constructed. Results The regression equations constructed according to the parameters from six kinds of gait were statistically significant. The overall correct rate was predicted from high to low: walking forward with closed eyes (97.1%), walking backward with open eyes (92.9%), walking backward with closed eyes (88.6%), walking forward with open eyes (87.1%), turning head up and down with open eyes (85.7%), turning head left and right with open eyes(82.9%). The constructed early warning model for fall risk of the elderly mainly included five steps, namely, judgment, test, extraction, calculation and early warning, which was suitable for gait testing and evaluation of the elderly in the laboratory. Conclusions Parameters from six kinds of gait could predict the fall risk of the elderly. Among them, walking forward with closed eyes was best to predict the fall risk in the elderly. The established early warning model of fall risk for the elderly could be used to predict the fall risk of 65-75 year old people within one year, which could provide early warning based on the probability of falling, playing a positive effect on preventing falls in the elderly.

Objective To investigate the effect of bilateral knee osteoarthritis (KOA) ondynamic balance ability of ankle strategy in aged women. Methods The dynamic balance ability tester was used to test the balance score, the rotation speed, the maximum rotation speed, and the percentage of the target ball's residence time in each area of KOA patients (KOA group)and the general elderly (control group), and a comparative analysis between groups was conducted. Results The balance score of KOA group was lower than that of control group; the dynamic balance control ability of KOA group in the horizontal direction was basically the same as that of control group, but the dynamic balance control ability of KOA group in the vertical direction was weaker than that of control group.Bilateral KOA reduced dynamic balance ability of ankle strategy in the aged women.It could not affect the left-right symmetric balance ability of the aged women, but it would reduce its forward-backward symmetrical balance ability. Conclusions Bilateral KOA aged women may be more likely to fall forward or backward, while not easy to fall laterally. For elderly female patients with bilateral KOA, methods such as strengthening ankle joint strength, proprioception and responsiveness can be used to prevent falls that may be caused by reduced dynamic balance ability, especially falls in the forward and backward directions.

Objective:To explore the balance performance of young adults under the interference of different cognitive tasks,and the moderating effect of long-term physical exercise. Method:The static and dynamic balance of healthy young people with physical exercise habit and without physical exercise habit were tested under the interference of different cognitive tasks.One-way repeated mea-sures ANOVA was performed with the group variable(Group)as the between-subjects factor and the results of multiple balance tests(Task)as the within-subjects variable. Result:Long term physical exercise had a positive moderating effect on the static balance during calculation,singing,and writing interference,the static mediolateral symmetrical balance during writing interference,the static anteroposterior symmetrical balance during singing interference,and the dynamic balance during comput-ing interference(P＜0.05).The dual-task cost of young people was significantly reduced when they are dis-turbed by the corresponding cognitive tasks(P＜0.05).However,it had a negative regulatory effect on the stat-ic mediolateral balance of calculation interference,the static anteroposterior balance of reading interference,and the dynamic mediolateral balance of calculation and singing interference(P＜0.05). Conclusion:Long term physical exercise has a significant moderating effect on young people's dynamic and static balance performance when different cognitive tasks are disturbed.

ObjectiveTo observe the clinical efficacy of Tongfu Xiezhuo enema in treating stage 3-4 chronic kidney disease （CKD） and the effect of the therapy on the neutrophil-to-lymphocyte ratio （NLR） as an inflammation marker. MethodSixty patients diagnosed with stage 3-4 CKD who visited the Nephrology Department of the First Affiliated Hospital of Heilongjiang University of Chinese Medicine from December 2022 to June 2023 were included and randomly assigned into observation and control groups in a ratio of 1∶1. The control group received conventional therapy plus Shenkang suppositories， while the observation group received conventional therapy plus Tongfu Xiezhuo enema. After 8 weeks of treatment， the clinical efficacy was assessed based on the changes in traditional Chinese medicine （TCM） symptom scores， renal function indicators， and NLR. Result① Both groups showed decreases in TCM symptom scores after treatment （P<0.01）， and the decreases were more significant in the observation group than in the control group （P<0.05）. The total response rate of TCM symptoms in the observation group was 79.31% （23/29）， which was higher than that （62.96%， 17/27） in the control group （Z=0.604，P<0.05）. ② After treatment， the observation group showed declined serum levels of creatinine （SCr）， blood urea nitrogen （BUN）， and cystatin C （Cys C） and increased glomerular filtration rate （GFR） （P<0.01）， and the control group showed lowered SCr level and increased GFR （P<0.05）. The observation group had lower SCr level and higher GFR than the control group after treatment （P<0.05）. The total response rate of renal function in the observation group was 79.31% （23/29）， which was higher than that （55.56%， 15/27） in the control group （Z=1.127，P<0.01）. ③ The NLR in the observation group decreased after treatment （P<0.05）， and it was lower than that in the control group （P<0.05）. ④ There were no significant differences in safety indicators between the two groups before and after treatment. ConclusionTongfu Xiezhuo enema ameliorated symptoms and improved renal function indicators in the patients with stage 3-4 CKD by reducing the NLR and inhibiting inflammation.
