BACKGROUND:At present,there are few reports on the postoperative efficacy of arthroscopic coracoid tunnel-free suspension fixation and coracoid single tunnel fixation in the treatment of acromioclavicular joint dislocation at home and abroad.The specific clinical efficacy of the two procedures and whether there are other risks need to be explored. OBJECTIVE:To compare the short-term postoperative clinical efficacy of arthroscopic TightRope band plate fixation with single tunnel fixation of the coracoid process and tunnel-free suspension fixation of the coracoid process in the treatment of acute type Ⅲ-Ⅴ acromioclavicular joint dislocation. METHODS:A retrospective analysis was performed in 45 patients with acromioclavicular joint dislocation who met the inclusion criteria admitted to the Sixth Affiliated Hospital of Xinjiang Medical University from June 2019 to September 2022,and were divided into coracoid single tunnel fixation group(20 cases)and coracoid tunnel-free suspension fixation group(25 cases)according to the surgical treatment plan.Operation time,incision length,blood loss,Constant-Murley score,visual analogue scale score,the American Shoulder and Elbow Surgeons(ASES)score and intraoperative and postoperative complications of the shoulder joint before operation,3 months after surgery and the last follow-up were compared between the two groups. RESULTS AND CONCLUSION:All patients successfully completed the operation,and there was no important nerve or blood vessel damage during the operation.The operation time of the coracoid tunnel-free suspension fixation group was significantly shorter than that of the coracoid tunnel-free suspension fixation group(P<0.05).There was no significant difference in intraoperative blood loss and incision length between the two groups(P>0.05).All patients were followed up for 12 to 24 months,with an average of(15.29±2.73)months.In the coracoid single tunnel fixation group,at 3 months after operation and the final follow-up,the visual analogue scale score was significantly lower than the preoperative score(P<0.05);Constant-Murley score and ASES score were significantly increased compared with the preoperative values(P<0.05).In the coracoid tunnel-free suspension fixation group,at 3 months after operation and the final follow-up,the visual analogue scale score was significantly lower than the preoperative score(P<0.05);the Constant-Murley score and the ASES score were both significantly higher than the preoperative scores(P<0.05).At 3 months after operation,the Constant-Murley score of the coracoid tunnel-free suspension fixation group was higher than that of the coracoid single tunnel fixation group(P<0.05),while there was no significant difference in visual analogue scale and ASES scores between the two groups(P>0.05).There was also no significant difference in the visual analogue scale,Constant-Murley,and ASES scores between the two groups at the corresponding time points before surgery and at the final follow-up(P>0.05).Intraoperative and postoperative complications:In the coracoid single tunnel fixation group,there was one case of coracoid cortical rupture and fracture during the tunnel drilling during the operation,and one case of a loss of reduction at 3 months after operation,which was repositioned and fixed with hook plate transposition of the coracoacromial ligament.All patients had good acromioclavicular joint function recovery and no re-dislocation at the final follow-up.All patients in the coracoid tunnel-free suspension fixation group did not suffer from coracoid fractures,loss of reduction and other complications during surgery,postoperatively and at the last follow-up.To conclude,these two arthroscopic treatments for acute type Ⅲ-Ⅴ acromioclavicular joint dislocation have the advantages of less trauma,reliable reduction and fixation,and good recovery of shoulder joint function after operation.However,compared with the coracoid single tunnel technique,the coracoid tunnel-free suspension fixation requires shorter time,faster recovery of shoulder joint function in the short term,and avoids the establishment of bone tunnels on the coracoid process,which reduces the probability of iatrogenic fracture of the coracoid process during operation and provides a higher degree of safety.

Inner ear diseases are common in the field of otolaryngology,including hearing loss,tinnitus and peripheral vestibular dysfunction.Their pathogenesis is relatively complex,which is one of the hot spots in current research.A large number of studies have demonstrated that sleep disorder is an important inducement of inner ear diseases.This paper reviews the impact of sleep deprivation on inner ear diseases in order to pro-vide a theoretical basis for the mechanisms of sleep deprivation on inner ear diseases.

According to the theory of "one qi circumference"， it is believed that qi movement disorder of zang-fu organs and dysfunction of qi transformation are the pathogenesis of rheumatoid arthritis （RA）. Zang-fu organs disorder is caused by spleen-stomach depletion and dampness pathogen obstruction， while qi transformation dysfunction is due to spleen-kidney yang qi depletion. For treatment， it is recommended to put focus on regulating qi movement of zang-fu organs， and promoting qi transformation. In clinical practice， the method of fortifying spleen and removing dampness can be used to restore ascending and descending function of the center， with Shengyang Yiwei Decoction （升阳益胃汤）， Sijunzi Decoction （四君子汤）， Shenling Baizhu Powder （参苓白术散） in their modifications. The method of supplementing and replenishing liver and kidney can be used to unblock the ascending path of qi movement， with Buxue Rongjin Pill （补血荣筋丸）， Duhuo Jisheng Decoction （独活寄生汤）， Dabuyin Pill （大补阴丸）， Liuwei Dihuang Pill （六味地黄丸） in their modifications. To unblock and regulate the downward path of the waterway， it is advised to diffuse lung and direct qi downward using Guizhi Decoction （桂枝汤）， Mahuang Decoction （麻黄汤） in their modifications. To restore qi transformation function of zang-fu organs， the method of warming and tonifying spleen and kidney is recommended with formulas such as modified Sini Decoction （四逆汤） and Shenqi Pill （肾气丸）.

Objective To investigate the role of TLR4/NF-κB signaling pathway in mediating sleep depriva-tion induced endolymphatic hydrops.Methods A total of 30 healthy sprague-dawley(SD)rats were randomly di-vided into the control group、big platform control group,and 2 w,3 w,4 w sleep deprivation group,with 6 rats in each group.Modified multiple platform method was adopted to establish the rat sleep deprivation model.Before and after the experiment,the open field and acoustic brain-stem response(ABR)was conducted to evaluate the behavior and hearing level.After ABR test,blood samples were collected from abdominal aorta,and serum levels of TNF-αand MCP-1 were detected by ELISA.The cochlea was dissected,the severity of endolymphatic hydrops was as-sessed by calculating the ratio of the cross sectional area of the membranous cochlear duct(SM)to that of the mem-branous cochlear duct+scale vestibuli(SM+SV).Positive expression of IL-1β,TNF-α,MCP-1,TLR4,NF-κB P65 in rat cochlear tissues was detected via immunohistochemical staining.After the experiment,the changes of hearing level,the severity of endolymphatic hydrops and TLR4/NF-κB signaling pathway related proteins and down-stream inflammatory factors expression level were observed.The correlation between TLR4/NF-κB signaling path-way and hearing level and endolymphatic hydropsin rats was analyzed.Results ABR results showed an increased threshold of wave Ⅱ in the sleep deprivation group compared to those of the control group and big platform control group(P＜0.05).The rate of hydrops was 0％in control and big platform control groups,16.67％in 2w sleep deprivation group and 25％in 3 w and 4 w sleep deprivation group.The concentrations of TNF-αand MCP-1 in ser-um of rats in sleep deprivation groups were higher than those in control and big platform control groups,and the 4w sleep deprivation group were statistically significant compared with control and big platform control groups.The ex-pressions of IL-1β,TNF-α,MCP-1,TLR4 and NF-κB P65 in the cochlear spiral ganglion,spiral canal,stria vascu-laris and spiral ligament of rats in sleep deprivation groups were higher than those in control and big platform control groups.Conclusion Sleep deprivation may induce endolymphatic hydrops by the TLR4/NF-κB signaling pathway.

Professor Li Candong puts forward the"five differentiation"thinking in TCM:symptom differentiation,syndrome differentiation,disease differentiation,person differentiation and mechanism differentiation.This article discussed the thinking and method of application of classical prescriptions based on the mode of"five differentiation".Treatment based on symptom differentiation is a quick method of application of classic prescriptions,which includes searching for specific symptoms or symptom groups and according to special tongue images.Treatment based on syndrome differentiation is a commonly used method in classic prescriptions,distinguishing between primary and secondary syndromes and the authenticity of cold and heat.Treatment based on disease differentiation is the inherent meaning of classic prescriptions,which is mainly to distinguish six meridian diseases and special prescriptions for specific diseases.Treatment based on person differentiation embodies the individual differences in the use of classic prescriptions,which include age,gender,constitution and abdominal syndrome.Treatment based on mechanism differentiation is an ingenious method used by classic prescriptions.When practicing clinical medicine,we should adhere to the integrated mode of"five differentiation"in the application of classic prescriptions,comprehensively considering the five dimensions,in order to improve the accuracy and effectiveness of the application of classic prescriptions,reveal and improve the academic system of classic prescriptions,and better guide their clinical application.

Objective To explore the efficacy and safety of intravenous infusion of tirofiban after mechanical thrombectomy in elderly patients with acute anterior circulation intracranial athero-sclerotic stenosis-related large vessel occlusion(ICAS-LVO).Methods A retrospective analysis was conducted on 106 elderly patients with acute anterior circulation ICAS-LVO undergoing me-chanical thrombectomy in our hospital from June 2021 to August 2023.After operation,38 pa-tients receiving 48-hour intravenous infusion of tirofiban at a drip rate of 0.1 μg/(kg·min)were assigned into experimental group,while the other 68 patients undergoing the infusion for only 24 h served as the control group.The indicators related to efficacy(90-day good prognosis rate)and to safety[intracerebral hemorrhage(ICH),symptomatic intracerebral hemorrhage(sICH),and 90-day mortality rate]were compared between the 2 groups.Multivariate logistic regression model was employed to analyze the influencing factors for good prognosis.Results The experimental group exhibited a significantly higher rate of 90-day favorable prognosis than the control group(52.6％vs 29.4％,P=0.018),but no significant differences were observed in the rates of ICH,sICH,and 90-day mortality between the 2 groups(P＞0.05).Multivariate logistic regression anal-ysis indicated that intravenous tirofiban administration for 48 h(OR=2.554,95％CI:1.067-6.116,P=0.034)and NIHSS score at admission(OR=0.887,95％CI:0.822-0.957,P=0.001)were independent influencing factors for 90-day prognosis in elderly patients undergoing mechani-cal thrombectomy due to acute anterior circulation ICAS-LVO.Conclusion In elderly acute ante-rior circulation ICAS-LVO patients receiving mechanical thrombectomy,postoperative intrave-nous tirofiban infusion for 48 h shows better improvement for 90-day prognosis than for 24 h,and has no effect on increasing the risk of sICH.

Objective:To investigate the efficacy and safety of neoadjuvant therapy with trastuzumab and pertuzumab combined with taxane and platinum drugs (TCbHP) regimen for human epidermal growth factor receptor 2 (HER2)-positive breast cancer.Methods:A retrospective case series study was conducted. The clinical data of HER2-positive breast cancer patients who received neoadjuvant therapy with 21-day TCbHP regimen and completed subsequent surgery in 11 tertiary-level hospitals in Hebei Province from June 2019 to December 2021 were retrospectively analyzed, and the total pathological complete remission (tpCR) rate, the incidence of grade ≥3 adverse events, and the completion rate of the established regimen were statistically analyzed.Results:A total of 78 female patients were included and the median age [ M ( Q1, Q3)] was 54.0 years (48.5 years, 57.5 years). The tpCR rate was 64.1% (50/78). Subgroup analysis showed that the tpCR rate in the HER2 immunohistochemistry (IHC)+++ group was higher than that in the HER2 IHC++ and fluorescence in situ hybridization-positive group [68.6% (48/70) vs. 25.0% (2/8)], and the difference was statistically significant ( χ2 = 4.18, P = 0.041); the tpCR rate in the hormone-receptor negative group was higher than that in the hormone-receptor positive group [81.8% (27/33) vs. 51.1% (23/45)], and the difference was statistically significant ( χ2 = 7.80, P = 0.005); the tpCR rate in the albumin-bound paclitaxel group was higher than that in the docetaxel group [72.3% (34/47) vs. 48.3% (14/29)], and the difference was statistically significant ( χ2 = 4.46, P = 0.035). The incidence of ≥ grade 3 adverse reactions was 12.8% (10/78) in 78 patients, and the completion rate of the established regimen was 92.3% (72/78). Conclusions:Neoadjuvant therapy with TCbHP regimen for HER2-positive breast cancer shows a definite efficacy, good safety and tolerance.

Objective:By detecting the levels of proteins in the Toll-like receptor-4/nuclear factor-κB （TLR4/NF-κB） signaling pathway and downstream proinflammatory cytokines in peripheral blood of patients with Meniere's disease （MD）, Pittsburgh Sleep Quality Index （PSQI） scores were collected to investigate the correlation between sleep disorders and MD and the role of TLR4/NF-κB signaling pathway in mediating sleep disorders inducing MD. Methods:Thirty-two MD patients and 20 family members of patients without middle ear and inner ear related diseases were selected. Basic data, PSQI and fasting peripheral blood of all subjects were collected. Enzyme linked immunosorbent assay.The levels of interleukin-1β（IL-1β）, tumor necrosis factor-α（TNF-α）, monocyte chemokine-1（MCP-1）, Toll-like receptor 4（TLR4） and nuclear factor-κB（NF-κB） in peripheral blood were detected by ELISA, and the data were statistically analyzed. Results:①PSQI score of MD group was higher than that of normal control group, and the difference was statistically significant（P<0.01）; The scores of every factors of PSQI in MD group were higher than those in normal control group, and the scores of factors 2, 4 and 6 were significantly different from those in normal control group. ②In the MD group, there were 18 patients with sleep disorders, with a prevalence rate of 56.25%, including 6 males with a prevalence rate of 50.00% and 12 females with a prevalence rate of 60.00%. ③The levels of five test indexes in MD group, sleep disorder group and non-sleep disorder group were higher than those in control group, and the levels of TLR4 and NF-κB in MD group were significantly different from those in control group（P<0.05）. The levels of IL-1β, TNF-α, TLR4 and NF-κB in sleep disorder group were significantly different from those in control group（P<0.05）. The levels of five test indexes in non-sleep disorder group were not statistically significant compared with those in control group. The levels of five test indexes in the MD sleep disorder group were higher than those in the MD group and the non-sleep disorder group, with no statistical significance. The levels of five test indexes in MD group were higher than those in non-sleep disorder group, with no statistical significance（P>0.05）. Conclusion:①Sleep disorders may be one of the important predisposing factors of some MD, and the effects of sleep disorders on MD are different between the sexes. ②Sleep disorders may activate TLR4/NF-κB signaling pathway to induce MD. The selection of TLR4/NF-κB signaling pathway related proteins and downstream pro-inflammatory factor inhibitors to intervene MD may provide a new idea for protecting the hearing balance function of MD.

Two male patients (75 years and 51 years, respectively) suffered infection of novel coronavirus after minimally invasive surgery for esophageal squamous cell carcinoma in Sichuan Cancer Hospital since December 2022. Both patients developed severe hypoxemia after surgery, and were treated with advanced oxygen therapy, antiviral therapy, hormone shock therapy, antibiotic anti-infection and nutritional support. The two patients stayed in the intensive care unit for 6 days and 8 days respectively. They were transferred to the general ward for symptomatic treatment and were discharged successfully. Both patients required low-flow oxygen maintenance after discharge. On the 20th day of follow-up after discharge, patient 1 still needed low-flow oxygen, his oxygen saturation could be maintained above 97%, but intermittent deoxygenation could be performed for half an hour. Patient 2 was in good condition on 35 days after discharge.

Review of historical literature showed that the understanding of the indicated disease location of Modified FuMai Decoction （复脉汤加减方） has evolved from the upper jiao （焦） to the middle and lower jiao. Initially， it is used for the treatment of yin deficiency of both yin and yang in the upper jiao， changes to supplement stomach and produce fluids in the middle jiao， and is used to protect yin， clear the pathogens， conslidate yin and subdue yang so as to store the true yin of lower jiao. The unchanging principle of Fumai Decoction modifications is nourishing yin， while the changing aspects are determining the secondary treatment methods based on disease location of sanjiao， concomitant disease natures， internal injury or external contraction， warm disease or cold damage， thereby choosing the corresponding added or subtracted herbs， and providing reference for the application of classical formulas.
