Objective: To investigate the clinical efficacy of acupuncture combined with tuina in treating patients with cervical vertigo. ＜br> Methods: According to the principle of randomization, 258 cases with cervical vertigo who met the inclusion criteria for the study were randomly divided into an observation group and a control group, with 129 cases in each. The patients in the observation group received acupuncture combined with tuina therapy, while those in the control group were just treated by the same acupuncture therapy as in the observation group. After 10-day continuous treatments, the clinical efficacies of the two groups were analyzed and compared. ＜br> Results: The total effective rate of the observation group was 100%, versus 86.0% of the control group, and the difference was significant (P＜0.05). After treatment, cervical range of motion (ROM) scores in both groups were statistically significantly different from those before treatment (allP＜0.05); in addition, there was a statistically significant difference in inter-group comparison of ROM score (P＜0.05). ＜br> Conclusion: Compared with simple acupuncture treatment, acupuncture combined with tuina therapy has a better effect in improving the ROM of cervical vertigo patients, with higher clinical efficacy.

ObjectiveTo evaluate the efficacy and safety of Lianhua Qingke tablets in the treatment of acute bronchitis in children with the syndrome of phlegm-heat obstructing lung. MethodA randomized， open， parallel controlled， and multi-center clinical study was conduted. Children with acute bronchitis （syndrome of phlegm-heat obstructing lung） were randomly assigned to an observation group and a control group. The control group received routine basic treatment， and the observation group was treated with Lianhua Qingke Tablets on the basis of routine basic treatment. After 7 days of treatment， the clinical efficacy， TCM efficacy， time to symptom disappearance， time to cough disappearance， and clinical safety were compared between the two groups. ResultA total of 248 children were included （124 in the observation group and 124 in the control group）. After 7 days of treatment， the total response rate in terms of clinical efficacy in the observation group was 96.8% （120/124）， which was higher than that （90.3%， 112/124） in the control group （Z=-5.034， P<0.01）. The total response rate in terms of TCM syndrome in the observation group was 97.6% （121/124）， which was higher than that （93.5%， 116/124） in the control group （χ²=-5.326， P<0.01）. The scores of physical signs and TCM symptoms in the observation group were lower than those in the control group at the time of taking medicine for 3 days and 7 days （P<0.01）. The time to symptom disappearance and the time to cough disappearance in the observation group were shorter than those in the control group （P<0.01）. Drug-related adverse reactions occurred in neither group. ConclusionLianhua Qingke tablets demonstrate a definite effect on acute bronchitis in children with the syndrome of phlegm-heat blocking lung. The tablets can significantly shorten the course of disease and relieve cough and TCM symptoms， with high safety， which is worthy of clinical application and promotion.

Recently, returning straw to the fields has been proved as a direct and effective method to tackle soil nutrient loss and agricultural pollution. Meanwhile, the slow decomposition of straw may harm the growth of the next crop. This study aimed to determine the effects of rumen microorganisms (RMs) on straw decomposition, bacterial microbial community structure, soil properties, and soil enzyme activity. The results showed that RMs significantly enhanced the degradation rate of straw in the soil, reaching 39.52%, which was 41.37% higher than that of the control on the 30th day after straw return. After 30 d, straw degradation showed a significant slower trend in both the control and the experimental groups. According to the soil physicochemical parameters, the application of rumen fluid expedited soil matter transformation and nutrient buildup, and increased the urease, sucrase, and cellulase activity by 10%‒20%. The qualitative analysis of straw showed that the hydroxyl functional group structure of cellulose in straw was greatly damaged after the application of rumen fluid. The analysis of soil microbial community structure revealed that the addition of rumen fluid led to the proliferation of Actinobacteria with strong cellulose degradation ability, which was the main reason for the accelerated straw decomposition. Our study highlights that returning rice straw to the fields with rumen fluid inoculation can be used as an effective measure to enhance the biological value of recycled rice straw, proposing a viable solution to the problem of sluggish straw decomposition.

[摘 要] 目的：研究芳香烃受体（AHR）在乳腺癌中的表达及其对乳腺癌细胞增殖、凋亡和药物敏感性的调控机制。方法：通过GEPIA数据库数据分析乳腺癌组织及癌旁组织中AHR的表达水平，探讨其与患者生存期的关联。利用基因敲低和过表达技术构建AHR表达变化的乳腺癌细胞，采用CCK-8实验、细胞计数和流式细胞分析等方法评估AHR对细胞增殖、凋亡和药物敏感性的影响，通过免疫印迹法验证相关分子机制。此外，利用AHR激动剂6-甲酰基吲哚并[3,2-B]咔唑（FICZ）研究外源性激活AHR对乳腺癌细胞多柔比星（DOX）敏感性的影响。结果：GEPIA数据库数据分析结果显示，乳腺癌组织中AHR呈明显低表达（P < 0.05）；对155例乳腺癌患者的生存期进行统计分析也显示AHR低表达与不良预后呈正相关（P < 0.05）。敲低AHR促进细胞增殖（P < 0.05），过表达则能抑制其增殖（P < 0.05）并促进其凋亡（P < 0.05）。外源激活AHR能增强乳腺癌细胞对DOX的敏感性（P < 0.05）。AHR可与MYC基因启动子结合，抑制MYC表达（P < 0.05），从而影响乳腺癌的进展。结论：AHR在乳腺癌中通过调控MYC表达影响细胞增殖和凋亡，外源激活AHR可能成为提高乳腺癌细胞对DOX敏感性的治疗策略。
