Objective To observe the clinical efficacy of thumb-tack needling for subcutaeous embedding combined with joint mobilization in the treatment of post-stroke shoulder-hand syndrome.Methods A total of 80 patients with post-stroke shoulder-hand syndrome were randomly divided into a treatment group and a control group,with 40 patients in each group.Both groups were given arthrocentesis,the control group was given ordinary acupuncture on the basis of arthrocentesis,and the treatment group was combined with thumb-tack needling for subcutaeous embedding.One course of treatment was 4 weeks and a total of 4 weeks of treatment was given.After 1 month of treatment,the clinical efficacy of the two groups was evaluated.The changes of Visual Analogue Scale(VAS)of pain scores and simplified Fugl-Meyer Assessment(FMA)scores,as well as the pain-free passive forward flexion and abduction of the shoulder joint of the affected limb were observed before and after treatment.The Simple Quality of Life Scale(SF-36)scores of the patients in the two groups were compared after treatment.The safety and the occurrence of adverse reactions in the two groups were also evaluated.Results(1)The total effective rate was 95.00%(38/40)in the treatment group and 80.00%(32/40)in the control group.The efficacy of the treatment group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the VAS scores and upper extremity FMA scores of the patients in the two groups were significantly improved(P＜0.05),and the treatment group was significantly superior to the control group in improving the VAS scores and upper extremity FMA scores,and the differences were statistically significant(P＜0.05).(3)After treatment,the joint mobility of patients in the two groups were significantly improved(P＜0.05),and the improvement of shoulder joint movement in the treatment group was superior to that in the control group,and the difference was statistically significant(P＜0.05).(4)After treatment,the SF-36 Quality of Life Scale scores of the treatment group were significantly superior to those of the control group in terms of physical function,psychological function,emotional health,and social function levels,and the difference was statistically significant(P＜0.05).(5)There was no significant difference in the incidence of adverse reactions between the treatment group and the control group(P＞0.05).Conclusion Thumb-tack needling for subcutaeous embedding combined with joint mobilization exert certain effect in the treatment of post-stroke shoulder-hand syndrome.It can significantly improve the pain symptoms of patients,thus improving their quality of life,and the clinical effect is remarkable.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

The expression level of NOD-like receptors(NLRP3)inflammasome is significantly elevated in breast cancer tissues,and a high level of NLRP3 inflammasomes is closely associated with breast cancer metastasis.Activation of NLRP3 inflammasome can induce the release of inflammatory factors into the tumor microenvironment(TME).These inflammatory factors,by signaling to cancer cells,reshape the TME to promote tumor growth and invasion,ultimately facilitating the process of epithelial-mesenchymal transition.This equips cancer cells with the ability to establish distant metastases and increase the formation of metastatic lesions.This review addresses the current research status and prospects of NLRP3 inflammasomes in the breast cancer TME and their role in breast cancer metastasis.The goal is to provide new insights for the study of breast cancer metastasis mechanisms and treatment strategies.

Objective This study aimed to compare the current Essen rabies post-exposure immunization schedule(0-3-7-14-28)in China and the simple 4-dose schedule(0-3-7-14)newly recommended by the World Health Organization in terms of their safety,efficacy,and protection. Methods Mice were vaccinated according to different immunization schedules,and blood was collected for detection of rabies virus neutralizing antibodies(RVNAs)on days 14,21,28,35,and 120 after the first immunization.Additionally,different groups of mice were injected with lethal doses of the CVS-11 virus on day 0,subjected to different rabies immunization schedules,and assessed for morbidity and death status.In a clinical trial,185 rabies-exposed individuals were selected for post-exposure vaccination according to the Essen schedule,and blood was collected for RVNAs detection on days 28 and 42 after the first immunization. Results A statistically significant difference in RVNAs between mice in the Essen and 0-3-7-14 schedule groups was observed on the 35th day(P<0.05).The groups 0-3-7-14,0-3-7-21,and 0-3-7-28 showed no statistically significant difference(P>0.05)in RVNAs levels at any time point.The post-exposure immune protective test showed that the survival rate of mice in the control group was 20%,whereas that in the immunization groups was 40%.In the clinical trial,the RVNAs positive conversion rates on days 28(14 days after 4 doses)and 42(14 days after 5 doses)were both 100%,and no significant difference in RVNAs levels was observed(P>0.05). Conclusion The simple 4-dose schedule can produce sufficient RVNAs levels,with no significant effect of a delayed fourth vaccine dose(14-28 d)on the immunization potential.
