ObjectiveTo conduct a systematic review of the effect of active music therapy on cognitive function for older adults with cognitive impairment based on International Classification of Diseases, the 11th Revision (ICD-11), and International Classification of Functioning, Disability and Health (ICF). MethodsA PICO framework was constructed. Thematic keyword searches were conducted in databases including PubMed, Web of Science, Embase, CNKI, VIP, and Wanfang data, for literature on the effect of active music therapy on cognitive function for older adults with cognitive impairment, published up to November 5th, 2023. Information on authors, countries, publication date, sample characteristics, study designs, intervention methods, measurement tools and outcomes were extracted. The methodological quality of the researches was evaluated using the Physiotherapy Evidence Database (PEDro) scale. ResultsEight researches from six countries were included, which were all randomized controlled trials involving 356 older adults with mild cognitive impairment and dementia. The articles were published from 2014 to 2020, with an average of 7.4 of the PEDro scale. Active music therapy was used by singing and playing instruments. Interventions took place in hospitals, nursing homes, and health centers. The intervention duration ranged from mostly 30 to 60 minutes a time, with a few 120 minutes a time. Interventions were implemented mostly one to three times a week, lasting from eight to twelve weeks. Health outcomes focused on cognitive function, including overall cognitive function, executive function, attention function and memory function. ConclusionA theoretical framework for the benefits of active music therapy on the cognitive function for older adults with cognitive impairment has been constructed based on ICD-11 and ICF. Active music therapy can improve overall cognitive function, executive function, attention function and memory function for older adults with cognitive impairment.

Objective To investigate the clinical characteristics of female migraine patients with patent foramen ovale(PFO)and design a risk prediction model for PFO in female migraine patients(migraineur patients PFO risk prediction model,MPRPM).Methods Female migraine patients who visited Zhongshan Hospital,Fudan University from Jun 1,2019 to Dec 31,2022 were included.Preoperative information and follow-up results after discontinuation of medication were collected.Patients were divided into PFO-positive and PFO-negative groups based on transesophageal echocardiography results.A multivariate Logistic regression model and a random forest model were constructed,and the random forest model was validated multidimensionally.Key features were selected based on the mean decrease accuracy(MDA)to construct MPRPM.Results A total of 305 female patients were included in the study,with 204 patients in the PFO-positive group and 101 patients in the PFO-negative group.Multivariate Logistic regression analysis showed that age at migraine onset,attack frequency,severe impact on life during attacks,exercise-related headaches,menstruation-induced headaches,aura migraines,and a history of cryptogenic stroke were predictive factors for PFO positivity.The random forest model effectively predicted the incidence of PFO in female migraine patients,with an AUC of 0.895(95%CI:0.847-0.943).MPRPM demonstrated a sensitivity of 71.6%and specificity of 91.1%(AUC:0.862,95%CI:0.818-0.906,P<0.001).The optimal cut-off value was 2.5 points.Patients correctly classified by the model showed a higher rate of symptom improvement compared to incorrectly classified patients(94.3%vs.82.0%,P=0.023).Conclusion We identified predictive factors for PFO in migraine patients.MPRPM can provide guidance in the diagnostic process and therapeutic decision-making for female migraine patients,assist in patient triage,and reduce the healthcare burden.

Objective To investigate the efficacy and safety of a new type of self-made bone drill applied to percutaneous transforaminal endoscopic discectomy for L5/S1 intervertebral disc herniation.Methods The clinical data of 52 patients with L5/S1 intervertebral disc herniation admitted to our hospital were retrospectively analyzed.All patients underwent percutaneous transforaminal endoscopic discectomy,with a new type of self-made bone drill for foraminoplasty during the surgery.The surgical conditions and occurrence of complications were recorded.The pain of patients before surgery,3 days after surgery,3 months after surgery,6 months after surgery,and 1 year after surgery was assessed by visual analogue scale(VAS);and the neurological function improvement before and after surgery was evaluated by Oswestry disability index(ODI).Results All patients underwent successful surgery without serious complications or recurrence after surgery.The VAS and ODI scores of patients 3 days,3 months,6 months,and 1 year after surgery were significantly lower than those before surgery(P<0.05).Conclusion The self-made new bone drill can significantly improve the efficiency of foraminoplasty and ensure surgical safety,with satisfactory early clinical effect.

ObjectiveTo investigate the analgesic action and mechanism of intrathecal 2R， 6R-hydroxynorketamine （2R， 6R-HNK） on spared nerve injury （SNI）-induced chronic neuropathic pain （CNP） in female mice. MethodsSNI was used to establish acute and chronic CNP models in female mice. The mice were randomly divided into different groups with administration of vehicle， 2R， 6R-HNK or S-ketamine （10 mg/kg intraperitoneal injection/i.p. or 7， 21 μmol/L intrathecal injection/i.t.） at 3 weeks after or 30 min/1 d before operation （n = 3 - 7 mice/group）. The curative or preventive effect of 2R， 6R-HNK was evaluated by mechanical paw withdrawal threshold （PWT） and the analgesic efficiency. Finally， immunofluorescence and RT-PCR of dorsal root ganglion （DRG） and spinal dorsal horn （SDH） were used to explore the possible mechanisms. ResultsCompared with vehicle， intrathecal injection of 2R， 6R-HNK largely reversed SNI-induced bilateral mechanical allodynia in a delayed-and-dose-dependent way. Among them， 21 μmol/L 2R， 6R-HNK reached its maximum analgesic efficiency （75.32±7.69） % at 2 d. Pre-intrathecal delivery of 2R， 6R-HNK also delayed the development of bilateral mechanical hypersensitivity 2 - 3 d induced by SNI. Mechanically， 2R， 6R-HNK reversed not only the abnormal excitability of neurons in bilateral DRG and superficial SDH， but also the upregulation of calcitonin gene-related peptide （CGRP） and brain-derived nerve growth factor （BDNF） in DRG. ConclusionIntrathecal administration of 2R， 6R-HNK exerts an analgesic effect against CNP， probably via suppressing abnormal neuronal excitability in ascending pain pathway as well as down-regulating CGRP and BDNF expression in DRG neurons.

ObjectiveTo investigate whether there exists gender differences in mechanical pain hypersensitivity induced by the subcutaneous injection of macrophage colony-stimulating factor （M-CSF） in normal mice and to explore the preliminary mechanism. MethodsThirty 10-week-old C57BL/6J mice were randomly divided into three groups， (n = 10 mice/group, half male and half female). The albumin control group （BSA， 0.3 μg）， low dose M-CSF group （L M-CSF， 0.075 μg） and high dose M-CSF group （H M-CSF， 0.3 μg） received 50 μL BSA or M-CSF injected subcutaneously into the left medial thigh once daily for 3 consecutive days. Before and after drug administration， von-Frey mechanical sensitivity test was used to detect the mechanical paw withdrawal threshold （PWT） in each group. Immunofluorescence was performed to examine the expression changes of Ionized calcium-binding adaptor molecule 1 (Iba1) in skin， calcitonin gene-related peptide （CGRP） and phosphorylated ERK1/2 （p-ERK） in L5-L6 DRG and lumbar spinal dorsal horn. ResultsIn female mice， only high dose of M-CSF caused mechanical allodynia， whereas in male mice both doses produced marked allodynia. Mechanically， high-dose M-CSF induced massive aggregation of subcutaneous macrophages （marked by Iba1） in male and female mice， but more dramatic dependence in female mice. Similar gender differences were also found in the increase of p-ERK and CGRP expression in dorsal root ganglion （DRGs）. Notably， CGRP expression was especially elevated in the fibers of DRG in male mice. Correspondingly， the expressions of p-ERK and CGRP⁺ terminals in the superficial spinal dorsal horn of male mice were significantly higher than those of female mice after M-CSF treatment. ConclusionSubcutaneous injection of M-CSF triggers sexual dimorphism in mechanical pain hypersensitivity, which is related with differential changes in peripheral macrophage expansion and sensitization of the nociceptive pathway.

Objective: To understand HIV self-testing and related factors in men who have sex with men (MSM) in Shijiazhuang. Methods: From August to September 2020, convenient sampling was used to recruit MSM in Shijiazhuang. Online questionnaires were used to collect information about their demographic characteristics, sexual behaviors and HIV self-testing. logistic regression model was used to analyze the related factors associated with HIV self-testing. Results: In the 304 MSM respondents, 52.3% (159/304) had HIV self-testing in the past 6 months, and 95.0% (151/159) used fingertip blood HIV detection reagent. Self-purchase was the main way to obtain HIV testing reagents (45.9%, 73/159), followed by supply from MSM social organization (44.7%, 71/159). The reasons for having HIV self-testing were non-specific testing time (67.9%, 108/159) and privacy protection (62.9%,100/159), the reasons for having no HIV self-testing included inability of using (32.4%, 47/145), being unaware of HIV self-testing reagent (24.1%, 35/145), and worry about inaccurate self-testing results (19.3%, 28/145). Multivariate logistic regression analysis showed that being 18-29 years old (aOR=2.68, 95%CI: 1.20-5.94), obtaining free HIV self-testing kits in recent 6 months (aOR=8.61, 95%CI: 4.09-18.11) and making friends through Internet and social software (aOR=2.68, 95%CI: 1.48-4.88) were positive factors for having HIV self-testing. Conclusion: HIV self-testing is a more flexible and convenient way to detect HIV in MSM, and the promotion of HIV self-testing in MSM should be strengthened to further increase the HIV detection rate in this population.

Retinoblastoma(RB)is the most common intraocular malignant tumor of children. Chemotherapy is a preferred method in RB treatment, which includes intravenous chemotherapy, intra-arterial chemotherapy and intravitreal chemotherapy. However, the occurrence of chemotherapy resistance often leads to the failure of eye-preserving treatment in RB patients. Therefore, exploring the mechanism of the occurrence of chemotherapy resistance and searching for new strategies and combined medicines for RB treatment are of great clinical significance. This article reviews that RB cells obtain chemotherapy resistance through ATP binding cassette protein(ABC transporter), non-coding RNA, epigenetics modification, autophagy, epithelial mesenchymal transformation, extracellular matrix changes and other ways, and the potential therapeutic targets for chemotherapy resistance are also summarized, in the hope of providing some references for further research on chemotherapy resistance of RB.

The dental operative microscope has been widely employed in the field of dentistry, particularly in endodontics and operative dentistry, resulting in significant advancements in the effectiveness of root canal therapy, endodontic surgery, and dental restoration. However, the improper use of this microscope continues to be common in clinical settings, primarily due to operators' insufficient understanding and proficiency in both the features and established operating procedures of this equipment. In October 2019, Professor Jingping Liang, Vice Chairman of the Society of Cariology and Endodontology, Chinese Stomatological Association, organized a consensus meeting with Chinese experts in endodontics and operative dentistry. The objective of this meeting was to establish a standard operation procedure for the dental operative microscope. Subsequently, a consensus was reached and officially issued. Over the span of about four years, the content of this consensus has been further developed and improved through practical experience.

Objective:To understand the current status of monkeypox knowledge and related factors among men who have sex with men (MSM) in China.Methods:The survey was conducted in 30 provinces from September 5 to 10, 2022. With the assistance of social organizations of MSM, MSM respondents were recruited one-to-one by investigators through a convenient sampling method. Respondents log in to the questionnaire star to participate in the anonymous online survey. The sample size was estimated at 5 070 based on China's population infectious disease prevention literacy level of 25%. The self-administered online questionnaire collected information on sociodemographic, behavioral, HIV infection status, attention to monkeypox, and knowledge of monkeypox. The logistic regression model was used to analyze the factors associated with knowledge awareness of monkeypox.Results:Among 5 780 MSM subjects, the awareness rate of monkeypox knowledge was 31.8% (1 840/5 780). The results of multivariate logistic regression analysis showed that the related factors with higher awareness rate of monkeypox knowledge in MSM included the current address was in the eastern region ( OR=1.26, 95% CI: 1.01-1.56), college education level or above ( OR=1.50, 95% CI:1.14-1.97), the number of anal-sex partners in the last month was &ge;3 ( OR=1.71, 95% CI: 1.28-2.28) or 2 ( OR=1.36, 95% CI:1.07-1.73), and there was no homosexual group sex in the last month ( OR=1.20, 95% CI:1.01-1.43), they had no heterosexual behavior ( OR=1.28, 95% CI:1.02-1.62), were HIV negative ( OR=1.85, 95% CI:1.44-2.36) or HIV positive ( OR=1.65, 95% CI:1.27-2.16), and paid frequent attention to monkeypox information ( OR=7.08, 95% CI: 5.28-9.48), occasional attention ( OR=4.52, 95% CI: 3.49-5.86) or minimal attention ( OR=2.55, 95% CI: 1.93-3.37). Conclusions:MSM has some attention and understanding of monkeypox in China, but the awareness rate of monkeypox knowledge is not high. It is necessary to strengthen the awareness of monkeypox knowledge among the MSM population with junior middle school education or below, who ignore the epidemic of monkeypox, have not been tested for HIV, and have had homosexual group sex or heterosexual sex to promote monkeypox prevention and self monitoring among MSM.
