BACKGROUND:The incidence rate of chronic non-specific neck pain is high and the etiology is unknown.Myofascial pain and deep cervical flexor atrophy are the key factors.Extracorporeal shockwave therapy can improve microcirculation,relieve local pain,and delay the degenerative development of the cervical spine,while motion control training can significantly improve neck muscle strength and endurance and reduce neck pain.However,both methods have limited effectiveness when applied individually.OBJECTIVE:To explore the therapeutic efficacy of extracorporeal shock wave intervention combined with motion control training at the upper trapezius muscle on chronic non-specific neck pain.METHODS:Forty-two patients with chronic non-specific neck pain recruited from Shenyang Sport University were randomly divided into three groups:a shock wave group(n=14),in which extracorporeal shockwave intervention at the upper trapezius muscle was given for 10-15 minutes,once a week for 4 weeks;a training group(n=14),in which motion control training was given for 40-50 minutes,three times a week for 4 weeks;and a combination group(n=14),in which extracorporeal shockwave intervention at the upper trapezius muscle combined with motion control training was performed for 4 weeks.Patients were assessed for pain intensity,cervical spine function,upper trapezius muscle thickness,hemodynamic parameters,and serum interleukin 6 and tumor necrosis factor α levels before intervention,1 week and 4 weeks after intervention.RESULTS AND CONCLUSION:(1)Compared with the pre-intervention period,the visual analogue scale scores and neck disability index in the three groups were lower after 1 and 4 weeks of intervention(P＜0.05),and the visual analogue scale scores and neck disability index in the combination group were lower than those of the shock wave group and the training group(P＜0.05).(2)Compared with the pre-intervention period,the upper trapezius thickness increased in the training group and the combination group after 4 weeks of intervention(P＜0.05);the upper trapezius thickness was greater in the combination group than in the shock wave group and the training group after 4 weeks of intervention(P＜0.05).(3)The shock wave group and the combination group had an increase in the peak systolic velocity of the ascending segment of the transverse carotid artery(P＜0.05)and a decrease in the resistance index(P＜0.05)after 1 and 4 weeks of intervention,while the training group showed an increase in the peak systolic velocity of the ascending segment of the transverse carotid artery(P＜0.05)and a decrease in the resistance index(P＜0.05)after 4 weeks of intervention.The peak systolic velocity of the ascending segment of the transverse carotid artery in the combination group was higher(P＜0.05)and the resistance index was lower(P＜0.05)than those in the shockwave group and the training group after 1 and 4 weeks of intervention.(4)Compared with the pre-intervention period,the levels of interleukin 6 and tumor necrosis factor α were reduced in the shock wave and combination groups after 1 and 4 weeks of intervention(P＜0.05),and in the training group after 4 weeks of intervention(P＜0.05).After 1 and 4 weeks of intervention,the levels of interleukin 6 and tumor necrosis factor α were lower in the combination group than in the shock wave group and the training group(P＜0.05).To conclude,extracorporeal shock wave combined with motion control training for chronic non-specific neck pain significantly reduces pain and improves neck function,and the mechanism of action may be to promote the blood flow velocity at the trigger point,reduce blood flow resistance,reduce the serum levels of interleukin 6 and tumor necrosis factor α,and increase the thickness of the upper trapezius muscle.

Depressive disorders are common mental illnesses characterized by significant and persistent low mood, with features such as high prevalence, high disability rate, and high suicide rate. The microbiota-gut-brain axis may be one of the potential mechanisms underlying depressive disorders. Gut microbiota metabolites, as important mediators of MGBA signaling, play roles in depressive disorders through multiple pathways. These include short-chain fatty acids, which can regulate the transmission of the vagus nerve, inflammatory responses, and 5-hydroxytryptamine synthesis; secondary bile acids, which can activate farnesoid X receptor and Takeda G protein-compled receptor 5; and choline, which can regulate DNA methylation and trimethylamine N-oxide production. This article reviews the literature on the potential mechanisms of action of gut microbiota metabolites, such as short-chain fatty acids, secondary bile acids, and choline, in depressive disorders. The literature was retrieved from CNKI, PubMed, and Web of Science databases from 2010 to 2025. It aims to provide a theoretical basis for the prevention and treatment of depressive disorders.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective:To investigate the clinical application value of a novel filter's retraction hook capture technique of pull-assisted method for the endovascular retrieval of conical inferior vena cava (IVC) filters whose hook attached to the wall.Methods:From January 2020 to December 2024, patients with conical filters whose hook attached to the wall admitted at Beijing Jishuitan Hospital were enrolled consecutively.Results:A total of 46 patients underwent filter retrieval using filter's retraction hook capture technique of pull-assisted method. Among these patients, 39 cases (84.8%) were successful in filter retrieval, with the penetration distance of cranial anchor vertex of 3.3(2.5, 4.4) mm, and 13 (33.3%) filters were deformed. The other 7 cases were unsuccessful, with a penetration distance of cranial anchor vertex of 5.0 (4.3, 5.0) mm, and 6 (85.7%) filters were deformed. There was a statistically significant difference between the two groups ( P<0.05). One case (2.2%) had IVC injury, one case (2.2%) experienced filter fracture, and no symptomatic pulmonary embolism occurred. Logistic regression analysis showed that filter deformation was an independent dangerous factor for filter's retraction. Conclusions:Filter's retraction hook capture technique of pull-assisted method is effective in removing conical filters whose hook attached to the wall, with no symptomatic PE occurring. This method can be considered as a new adjuvant technique for filter retrieval.

Objective:To assess any effect of combining kinesio taping with Baduanjin in the management of upper cross syndrome (UCS).Methods:Thirty-nine college students with UCS were randomly divided into a kinesio taping group ( n=14), a Baduanjin group ( n=12) and a combined treatment group ( n=13). The kinesio taping and Baduanjin groups received taping and underwent Baduanjin training, respectively, while the combined treatment group received both interventions for 6 weeks. Before, as well as 3 and 6 weeks after the intervention, all were evaluated using a visual analogue scale (VAS), a neck disability index (NDI), and for forward head extension (FHA), round shoulder angle (FSA) and vital capacity (VC). Results:A significant decrease in the average VAS ratings and NDI scores, and better average FHA and FSA was observed in both groups after the experiment. There was also a significant increase in VC. At 6 weeks, all of the indicators were significantly better than three weeks earlier. The kinesio taping and Baduanjin groups showed significantly smaller average improvements than the combined group.Conclusions:Kinesio taping combined with Baduanjin can effectively alleviate pain associated with UCS, relieve cervical dysfunction, correct abnormal posture and increase lung capacity. Its efficacy is superior to that achieved through single interventions.

Specific tumor-targeted gene delivery remains an unsolved therapeutic issue due to aberrant vascularization in tumor microenvironment (TME). Some bacteria exhibit spontaneous chemotaxis toward the anaerobic and immune-suppressive TME, which makes them ideal natural vehicles for cancer gene therapy. Here, we conjugated ZIF-8 metal-organic frameworks encapsulating eukaryotic murine interleukin 2 (Il2) expression plasmid onto the surface of VNP20009, an attenuated Salmonella typhimurium strain with well-documented anti-cancer activity, and constructed a TME-targeted Il2 delivery system named Il2/ZIF-8@Salmonella. Both in vitro and in vivo experiments demonstrated that Il2/ZIF-8@Salmonella maintained the tumor-targeting feature of bacteria, and could be effectively phagocytosed by intratumoral macrophages, thus leading to the expression and secretion of IL2 in TME. The detailed analysis of tumor immune microenvironment (TIME) showed that one dose of combinatorial Il2/ZIF-8@Salmonella achieved synergistic actions on a potent remodeling of TIME, marked by the activation of cytotoxic T cells and M1-polarization of macrophages in TME, thus leading to significant anti-tumor effects in melanoma, orthotopic hepatocellular carcinoma, and pulmonary metastasis models. More importantly, Il2/ZIF-8@Salmonella exhibited high safety to major organs and hematopoietic systems. Taken together, we report a novel plasmid/ZIF-8@Salmonella system that simultaneously achieves effective TME-targeted delivery of therapeutic gene, as well as synergistic re-activation of TIME.

Objective To investigate the correlation between the Controlling Nutritional Status (CONUT) score and wound repair of diabetic foot ulcer (DFU). Methods A total of 80 DFU patients treated in the Hospital from November 20, 2019 to November 20, 2022 were randomly selected as the study objects and divided into non-wound repair group (n=47) and wound repair group (n=33) based on wound repair status. Wound repair and hospital stay were recorded; clinical characteristics and the CONUT score were compared between the wound repair group and the non-wound repair group; the influencing factors of DFU wound repair were analyzed by the multivariate Logistic regression model. Results The hospital stay of patients in the non-wound repair group was 16.00 (10.50 to 24.00) days, which was significantly shorter than 44.00 (31.00 to 61.80) days of patients in the wound repair group (P < 0.05). The total cholesterol (TC), ankle-brachial index (ABI), the CONUT score, and malnutrition rate of patients in the non-wound repair group were significantly higher than those in the wound repair group (P < 0.05). The results of multivariate Logistic regression analysis showed that the CONUT score, malnutrition, TC and ABI were the independent risk factors for wound repair of DFU (P < 0.05). Conclusion Malnutrition, ABI, TC and CONUT score in DFU patients can adversely affect wound repair, and the CONUT score can accurately predict the risk of wound repair in patients, serving as a reliable reference for clinicians in early assessment of DFU.
