Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

Objective:To investigate the distribution rules of artemisia pollen and the clinical sensitization characteristics of allergic rhinitis (AR) induced by artemisia pollen in three urban and rural areas of Inner Mongolia.Methods:From March to October 2019, in 3 central cities (Chifeng, Hohhot, Ordos) and rural areas of Inner Mongolia, an epidemiological investigation method combining multi-stage stratified random sampling and face-to-face questionnaire survey was adopted to screen suspected AR patients, and skin prick test (SPT) was applied for diagnosis. At the same time, pollen monitoring was carried out in 3 areas to analyze the distribution and clinical sensitization characteristics of artemisia pollen.SPSS26.0 statistical software was used to process all the data. Chi-square test was used to compare rates among different age, sex, region and nationality, Spearman test was used to describe correlation analysis, and pairwise comparison of positive rates among multiple samples was used Bonferroni method.Results:Among the 6 393 subjects, 1 093 cases were diagnosed with AR, and the prevalence of AR was 17.10% (1 093/6 393). Among them, pollen-induced allergic rhinitis, the prevalence of PiAR was 10.97% (701/6 393), accounting for 64.14%(701/1 093).The highest incidence was in the youth group (20-39 years old), accounting for 46.94% (329/701).The diagnosed prevalence was higher in females than in males (11.35% vs. 10.64%, χ2 value 12.304, P<0.001).The prevalence rate of ethnic minority was higher than that of Han nationality (13.01% vs. 10.65%, χ2 value 6.296, P=0.008).The prevalence in urban areas was also significantly higher than that in rural areas (18.40% vs. 5.50%, χ2 value 10.497, P<0.001).There was significant difference in prevalence rate among the three regions in Inner Mongolia (6.06% in Chifeng, 13.46% in Hohhot, 16.39% in Ordos, χ2 value 70.054, P<0.001).The main clinical symptoms of artemisia PiAR were sneezing (95.58%), nasal congestion (91.73%) and nasal itching (89.30%).Allergic conjunctivitis accounted for 79.60% (558/701), chronic sinusitis for 55.63% (390/701), asthma for 23.25% (163/701).The pattern of artemisia pollen sensitization was mainly multiple sensitization, and the frequency of clinical symptoms and clinical diseases induced by hypersensitization with other allergens accounted for more than that caused by single artemisia pollen. The spread period of Artemisia pollen in the three regions was from June to October, and the peak state was in August in summer. The peak time of clinical symptoms in artemisia PiAR patients was about 2 weeks earlier than the peak time of pollen concentration, and the two were significantly positively correlated ( R=0.7671, P<0.001). Conclusion:Artemisia pollens are the dominant pollens in late summer and early autumn in Inner Mongolia, and the prevalence of artemisia PiAR is high. Controlling the spread of Artemisia pollens is of great significance for the prevention and treatment of AR.

Objective:To evaluate the efficacy and safety of Xiao′er Huangjin Zhike Granules in the treatment of cough caused by acute bronchitis in children, which is defined in TCM terms as a syndrome of phlegm-heat obstructing the lung.Methods:This was a block-randomized, double-blind, placebo-controlled, multicenter clinical trial.From January 2022 to September 2023, 359 children aged 3 to 7 years old diagnosed as acute bronchitis (lung-obstructing phlegm-heat syndrome) were enrolled from 21 participating hospitals and randomly assigned to the experimental group and placebo group in a 3︰1 ratio, and respectively treated with Xiao′er Huangjin Zhike Granules and its matching placebo.Cough resolution/general resolution rate after 7 days of treatment was used as the primary efficacy outcome for both groups.Results:(1)On the seventh day of treatment, the rate of cough disappearance/basically disappearance in the experimental group and placebo group were 73.95% and 57.61% retrospectively, which had statistically significance ( P=0.001).(2)After 7 days of treatment, the median duration of cough disappearance/basic disappearance were 5 days and 6 days in the two groups , with a statistically significant difference ( P=0.006).The area under the curve of cough symptom severity time was 7.20 ± 3.79 in the experimental group and 8.20±4.42 in the placebo group.The difference between the two groups was statistically significant ( P=0.039).(3) After 7 days of treatment, the difference between TCM syndrome score and baseline was -16.0 (-20.0, -15.0) points in the experimental group and -15.0 (-18.0, -12.0) points in the placebo group, with significant difference between the two groups ( P=0.004).In the experimental group, the clinical control rate, the markedly effective rate, the effective rate and the ineffective rate were 49.04%, 28.35%, 16.48% and 6.13% severally; and in the placebo group, the clinical control rate, the markedly effective rate, the effective rate and the ineffective rate were 38.04%, 26.09%, 29.35%, and 6.52% separately, which had statistically significant ( P=0.014).(4) There was no significant difference in the incidence of adverse events or adverse reactions during the trial between both groups.Moreover, while adverse reactions in the form of vomiting and diarrhea were occasionally reported, no serious drug-related adverse event or adverse reaction was reported.(5)The tested drug provided good treatment compliance, showing no statistically significant difference from the placebo in terms of compliance rate. Conclusions:Based on the above findings, it can be concluded that Xiao′er Huangjin Zhike Granules provides good safety, efficacy, and treatment compliance in the treatment of cough caused by acute bronchitis, and lung-obstructing phlegm-heat syndrome, in children.

Objective To evaluate the effect of manual massage on complications after endoscopic foam sclerotherapy injection for the treatment of internal hemorrhoids.Methods Consecutive 113 patients with grade Ⅰinternal hemorrhoids were prospectively enrolled and completed endoscopic foam sclerotherapy.The patients were randomly divided into a massage group(n=65)and a control group(n=68).Massage group performed manual perianal massage,Visual analogue scale(VAS)was used to evaluate perianal pain.The postoperative bleeding,short-term and long-term efficacy were also compared.Results The median VAS of 24 h postoperation was 1.0(0.0,3.0)in massage group,which was significantly lower than 2.0(1.0,4.0)in control group,the difference was statistically significant(P=0.014).The no bleeding rate of one week postoperation was 84.6％in massage group,which was significantly higher than 64.7％in control group,the difference was statistically significant(P=0.009).After 12 weeks,6 months and 12 months of follow-up,there were no significant differences in cure rate and remission rate between the two groups(P＞0.05).Conclusion Manual massage after endoscopic sclerosing agent injection is beneficial to relieve postoperative pain of grade Ⅰ internal hemorrhoids and reduce bleeding.

Objective:To evaluate the impact of self-crosslinked hyaluronic acid (SCH) gel on endometrium recovery after artificial abortion.Methods:A multicenter, prospective randomized controlled trial was conducted across 18 hospitals from December 2021 to February 2023, involving 382 women who underwent artificial abortion. Participants were randomly allocated to receive either treatment with SCH gel (SCH group) or no treatment (control group) in a 1∶1 ratio. The primary outcome was endometrium thickness in 14 to 18 days after the first postoperative menstruation. Secondary outcomes included changes in menstrual volume during the first postoperative menstruation, menstruation resumption within 6 postoperative weeks, time to menstruation resumption, duration of the first postoperative menstruation, and incidence of dysmenorrhea.Results:Baseline characteristics of participants were comparable between the two groups (all P>0.05), with 95.3% (182/191) in SCH group and 92.7% (177/191) in the control group completed the study. The postoperative endometrial thickness in SCH group was significantly greater than that in the control group [(9.78±3.15) vs (8.95±2.32) mm; P=0.005]. SCH group also had significantly fewer participants with reduced menstrual volume [23 cases (12.6%, 23/182) vs 31 cases (17.5%, 31/177); P=0.038]. Although SCH group experienced less dysmenorrhea during the first postoperative menstrual period, this difference was not statistically significant [28.5% (51/179) vs 37.1% (65/175); P=0.083]. Outcomes were similar between SCH group and the control group regarding the proportion of participants who resumed menstruation within 6 weeks postoperatively, time to menstruation resumption, and duration of the first postoperative menstruation ( P=0.792, 0.485, and 0.254, respectively). No serious adverse events were observed during the study period, and no adverse events were attributed to SCH gel treatment. Conclusion:The application of SCH gel after artificial abortion is safe and might aid in the recovery of the endometrium.

Objective To investigate the effects and mechanisms of Tiaoqi Zhike Prescription(Ephedrae Herba,Armeniacae Semen Amarum,Fritillariae Thunbergii Bulbus,Scutellariae Radix,Trichosanthis Semen,etc.)on airway inflammation in cough variant asthma rats based on the MAPK/NF-κB signaling pathway.Methods Cough variant asthma rat model was established by ovalbumin sensitization.SD rats were randomly divided into blank group,model group,Dexamethasone group(0.5 mg·kg-1),Montelukast group(1.0 mg·kg-1)and Tiaoqi Zhike Prescription low-,medium-and high-dose groups(9.6,19.2,38.4 g·kg-1),with 10 rats in each group.Intragastric administration was given once a day for 14 consecutive days.The general condition of rats was observed and the number of coughs in rats within two minutes after atomization was recorded.HE staining and Masson staining were used to observe the pathological changes of lung tissue in rats.The levels of serum interleukin-1β(IL-1β),IL-6 and tumor necrosis factor-α(TNF-α)were detected by ELISA.The protein expression levels of p38 MAPK,p-p38,NF-κB p65 and p-p65 in lung tissue were detected by Western Blot.The mRNA expression levels of p38 MAPK and NF-κB p65 in lung tissue were detected by RT-qPCR.Results Compared with the blank group,the times of coughs in the model group was significantly increased(P＜0.01),and the pathological score of lung injury and the area ratio of collagen fibers were significantly increased(P＜0.01).The levels of serum IL-1β,IL-6 and TNF-α were significantly increased(P＜0.01).The protein expressions of p-p38,p-p65,p-p38/p38 and p-p65/p65 in lung tissue were significantly up-regulated(P＜0.01),and the mRNA expressions of p38 MAPK and NF-κB p65 were significantly up-regulated(P＜0.01).Compared with the model group,the cough frequency of rats in each administration group was significantly decreased(P＜0.01),the pathological score of lung injury and the area ratio of collagen fibers were significantly decreased(P＜0.01),the levels of serum IL-1β,IL-6 and TNF-α were significantly decreased(P＜0.01),and the protein expressions of p-p38 and p-p65 and the mRNA expressions of p38 MAPK and NF-κB p65 in lung tissue were significantly down-regulated(P＜0.05,P＜0.01).The protein expression ratios of p-p3/p38 and p-p65/p65 in the lung tissue of rats in the high-dose group of Tiaoqi Zhike Prescription were significantly down-regulated(P＜0.01).Compared with the Dexamethasone group and the Montelukast group,the number of coughs in the high-dose group of Tiaoqi Zhike Prescription was significantly reduced(P＜0.05).Compared with the Dexamethasone group,the serum levels of IL-1β,IL-6 and TNF-α in the high-dose group of Tiaoqi Zhike Prescription were significantly decreased(P＜0.01).Compared with the Montelukast group,the levels of serum IL-1β and TNF-α in the high-dose group of Tiaoqi Zhike Prescription were significantly decreased(P＜0.05,P＜0.01).Conclusion Tiaoqi Zhike Prescription can improve the cough symptoms of ovalbumin-induced cough variant asthma model rats,reduce airway inflammatory cell infiltration and airway remodeling,and reduce the levels of inflammatory cytokines IL-1β,IL-6 and TNF-α.The mechanism may be related to the regulation of MAPK/NF-κB signaling pathway.

OBJECTIVE: To explore the mechanism of Yifei Jianpi recipe for improving cigarette smoke- induced inflammatory injury and mucus hypersecretion in cultured human bronchial epithelial cells. METHODS: Serum samples were collected from 40 SD rats treated with Yifei Jianpi recipe (n=20) or normal saline (n=20) by gavage. Cultured human bronchial epithelial 16HBE cells were stimulated with an aqueous cigarette smoke extract (CSE), followed by treatment with the collected serum at different dilutions. The optimal concentration and treatment time of CSE and the medicated serum for cell treatment were determined with CCK-8 assay. The expressions of TLR4, NF-κB, MUC5AC, MUC7, and muc8 at both the mRNA and protein levels in the treated cells were examined with RT- qPCR and Western blotting, and the effects of TLR4 gene silencing and overexpression on their expressions were assessed. The expressions of TNF-α, IL-1 β, IL-6 and IL-8 in the cells were detected using ELISA. RESULTS: At the optimal concentration of 20%, treatment with the medicated serum for 24 h significantly lowered the mRNA and protein expressions of TLR4, NF- κB, MUC5AC, MUC7, and MUC8 in CSE- exposed 16HBE cells, and these effects were further enhanced by TLR4 silencing in the cells. In 16HBE cells with TLR4 overexpression, the expressions of TLR4, NF-κB, MUC5AC, MUC7, and MUC8 were significantly increased after CSE exposure and were lowered following treatment with the medicated serum (P < 0.05). The medicated serum also significantly lowered the levels of TNF-α, IL-1β, IL-6 and IL-8 in CSE-exposed 16HBE cells (P < 0.05). CONCLUSIONS In the 16HBE cell model of chronic obstructive pulmonary disease (COPD), treatment with Yifei Jianpi recipe-medicated serum improves inflammation and mucus hypersecretion possibly by reducing MUC secretion and inhibiting the TLR4/NF-κB signaling pathway.

Objective To compare the effects of Flexi-bar training in different exercise patterns on trunk stability muscles.Methods From June, 2020 to January, 2021, 21 healthy men in Beijing Bo'ai Hospital finished Flexi-bar exercise in seven patterns in random order, namely no vibration, two hands-front vibration, dominant hand-front vibration, non dominant hand-front vibration, two hands-up vibration, two hands-down vibration and two hands-back vibration. The average voltage of electromyography of upper trapezius, middle trapezius, lower trapezius, latissimus dorsi and lumbar multifidus were recorded with surface electromyography during seven kinds of Flexi-bar exercise.Results The average voltage of lumbar multifidus was the most as two hands-front vibration (F=42.362, P<0.001); however, it was the most for upper trapezius and lower trapezius as two hands-up vibration (F > 10.935, P<0.001), it was the most for latissimus dorsi as two hands-back vibration (F=35.243, P<0.001), and it was the most for ipsilateral middle trapezius as non dominant hand-front vibration (F=40.400, P<0.001).Conclusion Flexi-bar training can effectively activate the contraction of trunk stability muscles, and it can be optimized in targeted patterns.

Interleukins (ILs) and associated cytokines serve as the means of communication for immune cells and non-immune cells. The use of ILs in harnessing the immune system to cancer treatment has been a promising approach. ILs not only nurture an environment enabling cancer growth but also simultaneously trigger a productive tumor-directed immune response. These properties of ILs are increasingly being explored as a strategy to improve the outcomes of cancer. Here, we describe recently innovative technological approaches that have been developed to improve the pharmacokinetics, safety, and efficacies of IL-2, 15, 10, and 18 in the treatment of melanoma. Furthermore, the combination of ILs and immune checkpoint inhibition may synergize to reshape the tumor environment, thus yielding better clinical benefits in the future.
