Objective To observe the clinical efficacy of acupuncture combined with western medicine in the treatment of lumbar disc herniation(LDH)of qistagnation and blood stasis type.Methods A total of 62 cases of patients with LDH of qistagnation and blood stasis type were randomly divided into observation group and control group,with 31 cases in each group.The control group was given conventional western medicine for treatment,and the observation group was treated by acupuncture on the basis of the control group,the course of treatment covered three consecutive weeks.After three weeks of treatment,the clinical efficacy of the two groups was evaluated,and the changes in the Japanese Orthopedic Association(JOA)scores and Oswestry Disability Index(ODI)scores,as well as the Visual Analogue Scale(VAS)scores of pain,were observed before and after the treatment of the patients in the two groups.The changes in muscle tension,muscle hardness,and muscle elasticity of the multifidus muscle(MM)and lumbar multifidus muscle(LMM)before and after treatment were compared between the two groups.And the safety and the occurrence of adverse reactions in the two groups were evaluated.Results(1)The total effective rate was 96.77%(30/31)in the observation group and 74.19%(23/31)in the control group.The efficacy of the observation group was superior to that of the control group,the difference being statistically significant(P<0.05).(2)After treatment,the VAS,JOA,and ODI scores of the patients in the two groups improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,with a statistically significant difference(P<0.01).(3)After treatment,the muscle tension,muscle hardness,and muscle elasticity of LMM and MM of patients in the two groups were significantly improved(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(4)The incidence rate of adverse reactions was 9.68%(3/31)in the observation group and 9.68%(3/31)in the control group;the intergroup comparison showed that there being no statistically significant difference(P>0.05).Conclusion Acupuncture combined with western medicine in the treatment of LDH of qistagnation and blood stasis type can significantly improve the lumbar function and clinical symptoms of the patients,and improve the muscular performance of the patients'LMM and MM,so as to enhance their quality of life.

OBJECTIVE To analyze the relationship between LPR and common pharyngeal diseases and its risk factors.METHODS A total of 280 patients who were admitted to the Inpatient Department of Otolaryngology Head and Neck Surgery or Laryngoscopy Room of the First Affiliated Hospital of Harbin Medical University due to throat discomfort from September 2022 to May 2023 were selected as the study objects.All enrolled patients were required to complete the RSI and RFS scoring scales.According to the 2022 LPRD expert Consensus,RSI>13 and/or RFS>7 were classified as LPR group,and RSI≤13 and RFS≤7 are classified as non-LPR group.Chi-square test was used to analyze the differences in the incidence of common pharyngeal diseases such as upper respiratory tract papilloma,epiglottic cyst,vocal cord polyp,vocal cord leucoplakia,vocal cord cancer and hypopharyngeal cancer among different groups.Univariate Chi-square test analysis and multivariate binary logistic regression analysis were performed for gender,age,BMI,smoking and drinking history.All differences were statistically significant with P<0.05.RESULTS The prevalence of LPR in 280 patients with throat discomfort was 70.0%(196/280).There were statistically significant differences in the incidence of LPR group and non-LPR group in patients with vocal cord polyp(χ2=4.228,P<0.05),vocal cord leukoplakia(χ2=12.283,P<0.05),vocal cord cancer(χ2=4.103,P<0.05)and hypopharyngeal cancer(χ2=4.907,P<0.05),while there was no significant difference in the incidence of LPR group and non-LPR group in patients with papilloma of upper respiratory tract(χ2=0.183,P>0.05)and epiglottic cyst(χ2=0.556,P>0.05).Univariate analysis showed that there were significant differences in the incidence rates of smoking(χ2=20.403,P<0.05)and drinking(χ2=7.704,P<0.05)between the LPR group and the non-LPR group,while gender(χ2=0.01,P>0.05),age(χ2=8.147,P>0.05),BMI(χ2=2.060,P>0.05)had no significant difference.Multivariate logistic regression analysis showed that smoking(OR=3.390,95%CI:1.761-6.526,P<0.05)was an independent risk factor for LPR.CONCLUSION There is a high co-prevalence of LPR with vocal cord polyps,vocal cord leukoplakia,vocal cord cancer and hypopharyngeal cancer.Therefore,LPR should be evaluated when treating throat related diseases,and LPR should be actively treated if necessary.In addition,smoking and drinking are risk factors for LPR,so it is necessary to stop smoking and drinking alcohol when treating LPR.

Objective:To study the application value of narrow-band imaging in the diagnosis of laryngopharyngeal reflux. Methods:A total of 275 patients admitted to the inpatient department or laryngoscopy room of the Otolaryngology Head and Neck Surgery Department of the First Affiliated Hospital of Harbin Medical University from September 2022 to April 2023 due to throat discomfort were selected as the research subjects. All of them completed RSI, RFS scoring scales and electronic laryngoscopy（including ordinary white light and NBI）. According to the expert consensus of LPRD in 2022, RSI and RFS scoring scale were used as diagnostic criteria to divide them into LPR group and non-LPR group. Chi-square test was used to analyze the differences of positive rates of characteristic manifestations under NBI among different groups. The consistency of NBI and scale diagnostic methods was analyzed by Kappa, and RSI and RFS scoring were used as diagnostic criteria, The diagnostic efficiency of NBI method was analyzed. Results:There were 190 people in the LPR group, 157 of whom showed characteristic performance under the NBI mode, with a positive rate of 82.6%（157/190）; there were 85 people in the non-LPR group, with a positive rate of 18.8%（16/85）. There was a statistically significant difference in the positive rate between the two groups（χ²=102.47, P<0.05）. The consistency rate between RSI, RFS and NBI was 82.2%（226/275）. Kappa consistency analysis was used, and Kappa=0.605（P<0.05）, indicating good consistency between the two diagnostic methods. Using RSI and RFS as diagnostic criteria for LPR, the sensitivity of NBI diagnostic method was 82.6%（157/190）, specificity 81.2%（69/85）, positive predictive value 90.8%（157/173） and negative predictive value 67.6%（69/102）. Conclusion:Narrow-band imaging, as a new endoscopic imaging technique, can show small changes in mucosal surface micro vessels and play an important role in the diagnosis of laryngopharyngeal reflux.
