OBJECTIVE: To screen the optimal regimen of acupuncture and moxibustion for obstructive sleep apnea hypopnea syndrome (OSAHS), so as to provide the evidences for clinical decision-making. METHODS: From 7 databases in Chinese and English i.e. the Full-Text Database of China Journal Network (CNKI), Wanfang Data Knowledge Service Platform (Wanfang), VIP Information Chinese Journal Service Platform (VIP), Chinese Biomedical Literature Database (SinoMed), PubMed, Web of Science (WOS) and Cochrane Library, randomized controlled trial (RCT) articals of OSAHS treated with acupuncture and moxibustion were searched. The quality of evidence was evaluated with the modified Jadad scale, the evaluation index was established and the optimal regimen of acupuncture and moxibustion for OSAHS was screened by multi-index decision analysis. RESULTS: A total of 10 RCTs were included, and the filiform needling therapy was optimal in treatment of OSAHS. The acupoints included Lianquan (CV23), Danzhong (CV17), Zhongwan (CV12), and bilateral Kongzui (LU6), Pishu (BL20), Fenglong (ST40), Zusanli (ST36), Yinlingquan (SP9) and Zhaohai (KI6). Zusanli (ST36) received the reinforcing method, Pishu (BL20) and Fenglong (ST40) were stimulated with the reducing technique, and the rest acupoints with the uniform reinforcing-reducing. Each acupoint was manually manipulated once every 10 min during the needle retention for 30 min. Acupuncture was delivered once a day, 5 times a week and for consecutive 4 weeks. Among the included literature, the severity of disease was not reported in detail, the filiform needling was the dominant intervention, the local acupoints such as Lianquan (CV23) and Panglianquan (Extra) were mainly selected. The apnea-hypopnea index and the minimum oxygen saturation were taken as the evaluation indexes, and the effect was evaluated in reference to the generally accepted standards. The attention to safety evaluation was insufficient, the report on methodology was not adequate and the quality was low. CONCLUSION Filiform needling is the dominant therapy of acupuncture and moxibustion for OSAHS, and the local acupoints are considered specially. But the quality of clinical research should be improved.

OBJECTIVE: To explore the efficacy differences among different acupuncture frequencies for pain of temporomandibular disorders (TMD). METHODS: A total of 42 patients with TMD pain were randomly divided into a low-frequency group, a medium-frequency group, and a high-frequency group, with 14 patients in each group. All groups received acupuncture treatment at bilateral Hegu (LI4) and Yanglingquan (GB34), as well as ipsilateral Tinggong (SI19), Jiache (ST6), and Xiaguan (ST7), with each session lasting 30 minutes. The low-frequency group received acupuncture once per week, the medium-frequency group received acupuncture twice per week, and the high-frequency group received acupuncture three times per week, for a total duration of four weeks. The graded chronic pain scale (GCPS) score, visual analogue scale (VAS) score, jaw functional limitation scale-20 (JFLS-20) score, and pressure pain threshold (PPT) were assessed in the three groups before and after treatment, as well as at the four-week follow-up after treatment completion. RESULTS: Compared before treatment, GCPS and JFLS-20 scores were significantly decreased in all the groups after treatment (P<0.05), and VAS scores were significantly decreased in the high-frequency and medium-frequency groups (P<0.05), PPT values at different measurement sites were increased significantly in the high-frequency group (P<0.05). After treatment, GCPS, JFLS-20, and VAS scores in the high-frequency group were lower than those in the medium-frequency and low-frequency groups (P<0.05), while some PPT values were higher than the other two groups (P<0.05). At follow-up, GCPS, JFLS-20, and VAS scores remained significantly lower in all the groups compared to baseline (P<0.05), PPT values were increased significantly in the high-frequency and medium-frequency groups (P<0.05), with the high-frequency group showing lower GCPS, JFLS-20, and VAS scores and higher PPT values compared to the other two groups (P<0.05). CONCLUSION Acupuncture three times per week is more effective in reducing TMD pain intensity compared to once or twice per week, and can also alleviate some mandibular functional impairments. The therapeutic effects persist for at least four weeks after treatment completion.

OBJECTIVE: To observe the effects of moxibustion at "Shenque" (CV8) on urodynamics and the expression of brain-derived neurotrophic factor (BDNF) and immediate early gene (c-fos) in pontine micturition center (PMC), periaqueductal gray (PAG), medial prefrontal cortex (mPFC) of neurogenic bladder (NB) rats after spinal cord injury. METHODS: Twenty-four SPF female SD rats were randomly divided into a sham-operation group (6 rats) and a modeling group (18 rats). In the modeling group, T₉ complete spinal cord transection method was used to establish a neurogenic detrusor overactivity model, and the 12 rats with successful modeling were randomized into a model group and a moxibustion group, with 6 rats in each group. The rats in the moxibustion group were treated with ginger/salt-insulated moxibustion at "Shenque" (CV8), and 4 consecutive moxa cones were delivered in one intervention. Moxibustion was operated once daily and for 14 days. After intervention completion, the urodynamic indexes of rats in each group were detected. Fluorescence quantitative PCR was used to detect the mRNA expression of BDNF and c-fos in PMC, PAG and mPFC in rats. Western blot was used to detect the protein expression of BDNF and c-fos in PMC, PAG and mPFC. RESULTS: The rats in the sham-operation group did not show phasic detrusor contraction during bladder filling. Compared with the model group, the frequency and amplitude of the phasic detrusor contraction were reduced 5 min before urine leakage in the rats of the moxibustion group (P<0.05), and the duration of the first phasic detrusor contraction during bladder filling was prolonged (P<0.05). Compared with the sham-operation group, the mRNA and protein expression of BDNF and c-fos in PMC, PAG and mPFC increased in the model group (P<0.05). Compared with the model group, the mRNA and protein expression of BDNF and c-fos in PMC, PAG and mPFC decreased in the moxibustion group (P<0.05). CONCLUSION Moxibustion at "Shenque" (CV8) can improve the phasic contraction during bladder filling in NB rats after spinal cord injury, possibly by down-regulating the mRNA and protein expression of BDNF and c-fos in PMC, PAG, and mPFC.

Transcutaneous electrical stimulation equipment is a kind of characteristic therapeutic devices developed on the basis of the integration of traditional Chinese medicine (TCM) theory and modern science and technology, which is widely used in clinical practice. Significant breakthroughs have been made in the development of related devices such as transcutaneous electrical acupoint stimulation (TEAS) devices, transcutaneous electrical nerve stimulation (TENS) devices, and transcutaneous auricular vagus nerve stimulation (taVNS) devices in recent years. Although the market for these devices is vast, there are still limitations that need to be optimized in terms of electrode materials and power supply methods, bulky instrument size, cumbersome wiring, restricted applications, and inadequate intelligent functionality. In the future, it is still necessary to further build upon the theoretical foundation of TCM acupuncture, integrate a variety of modern scientific technologies to advance the intelligence and modernization of acupuncture equipment, and thereby improving its capabilities to support clinical practice and research.

After being treated with acupuncture, some patients with idiopathic tinnitus may experience a short-term aggravation of tinnitus symptoms on the original basis. These symptoms can be gradually relieved and the overall condition fluctuates towards recovery. This phenomenon has brought some difficulties to patients and clinicians. Based on the academic view of TCM, "destroying pathogens and re-building balance", and in association with the existing understanding of acupuncture in modern medicine for tinnitus, this paper briefly discusses the mechanism and influencing factors of symptom fluctuation in patients with idiopathic tinnitus after acupuncture treatment in terms of both TCM and modern medicine, and proposes the future direction in the research of symptom fluctuation, so as to promote the recognition of clinicians and patients on symptom fluctuation and make rational use of its positive effects. Besides, it is hoped that more researchers will pay attention to symptom fluctuation and advance the exploration of it in academic field.

Purpose To explore the clinical manifestations,imaging features,and histopathological characteristics of intravascular large B-cell lymphoma(IVL-BCL)involving the central nervous system(CNS).Methods Clinical and imaging data from 5 cases of IVL-BCL were collected.Immunohistochemical staining and FISH were performed to analyze their clinicopathological characteristics,with a comprehensive review of relevant literatures.Results All 5 pa-tients were elderly,with a male-to-female ratio of 4∶1,and an age of onset ranging from 53 to 67 years.The disease course varied from 4 months to 2 years.All patients had varying degrees of neurological damage symptoms.In this study,4 patients experienced varying degrees of weakness in the lower limbs.MRI findings were nonspecific,but all 5 patients showed evidence of cerebrovascular lesions.Histologically,the lesions were characterized by aggregates of lymphoid tumor cells within the lumens of small cerebral vessels,which could obstruct the lumens and cause ischemic and hypoxic changes.Tumor cells did not involve the extravascular brain parenchyma.Immunohistochemically,tumor cells widely expressed mature B-cell markers(CD19,CD20,CD79a,PAX5)with a high Ki67 proliferation index.All 5 patients received systemic chemotherapy after diagnosis,1 patient died,2 patients achieved clinical and physical symptom relief and were still under follow-up.2 patients were undergoing systemic examination before chemotherapy.Conclusion Intravascular large B-cell lymphoma involving the central nervous system is rare,and both clinical mani-festations and imaging examinations lack specific indicators.Preoperative diagnosis is very difficult and can only rely on diagnostic brain biopsy or pathological diagnosis after craniotomy.

Objective:To study the comparative genomic characteristics of Marmota himalayana-derived (referred to as marmota-derived) Brucella abortus (B.ab). Methods:The species and types of one strain of marmota-derived Brucella and one strain of human-derived Brucella isolated from the brucellosis epidemic area in Qinghai Province in the same year were identified. Meanwhile, DNA was extracted for whole genome sequencing and comparative genomics analysis (including phylogenetic tree construction, gene family clustering analysis, common/specific gene analysis, and genomic structural variation analysis, etc.). Results:Two Brucella strains from different hosts were identified as B.ab. By constructing a phylogenetic tree, the marmota-derived B.ab strain was grouped with strains from Heilongjiang Province and showed genetic correlation with strains from Russia. Human-derived B.ab strain was classified as a strain in Inner Mongolia Autonomous Region, Hebei Province, Beijing City, and Gansu Province. The multilocus sequence typing (MLST) of the two strains belonged to the ST2 type. Multiple locus variable-number tandem repeat analysis (MLVA) belonged to two new MLVA-8 and MLVA-11 genotypes, which were clustered in two subclusters of the same cluster and clustered with the strains from Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region, and Hebei Province. The pan-genome numbers of the marmota-derived B.ab and human-derived B.ab were 283 and 8, respectively; the number of core genes (common genes) was 68 and 2, respectively; and the number of unique genes was 3 and 4, respectively. The unique gene encoded proteins were inconsistent. In marmota-derived B.ab, the main ones were the ABC transporter ATP-binding protein, N-terminal acetyltransferase, and glucose/galactose transporter. The number of homologous genes of the marmota-derived B.ab and human-derived B.ab was 16 and 20, respectively; the number of translocation and inversion genes was 13 and 8, respectively; the number of deletion mutation genes was 11 and 14, respectively. Pathogenicity analysis showed that both strains had the mprF resistance gene, and the marmota-derived B.ab strain also carried bacitracin and macrolide resistance genes. Conclusions:Brucella exhibits cross-species genetic diversity. The proteins encoded by the unique genes of the marmota-derived B.ab mainly play a role in metabolic and epigenetic regulation. The strains cluster with B.ab strains from northern China, providing a reference for molecular epidemiology and pathogen tracing of B.ab infection.

Objective:To construct an evaluation system for the risk factors of PICC catheter malposition in patients with hematological diseases, providing a reference for the prevention of central venous access malposition in these patients.Methods:From July 2022, a literature review was conducted to retrieve literature published in database and website such as PubMed, Web of Science domestically and internationally related to the risk assessment system of PICC catheter malposition in hematology patients. After full-text screening and extraction, the articles were included in the system′s item pool. Through further discussions among the research group′s experts, in conjunction with evidence-based findings, the system′s consultation items were formulated. Using the Delphi expert consultation method, a standard for PICC catheter malposition risk assessment system applicable to hematology patients was ultimately formulated.Results:In this study, 25 experts were invited for consultation: 24 females and 1 male, with an average age of (48.36 ± 6.82) years. After two rounds of expert consultations and revisions, the risk factors for PICC catheter malposition in hematology patients were identified to include 4 first-level indicators: patient factors, treatment factors, catheter-related factors, and operational factors, along with 11 second-level indicators and 25 third-level indicators. The positive coefficients of the experts in the two rounds of consultations were 84% and 100%, respectively; the Kendall coordination coefficients were 0.22 and 0.55 (both P<0.05); and the expert authority coefficient was 0.93. Conclusions:The risk assessment scale for PICC catheter malposition in patients with hematological diseases has high expert recognition and good consistency, and has clinical practice and guiding value.

Objective To explore the diagnosis and treatment strategies for elderly patients with ground-glass opacity (GGO). Methods The imaging features and postoperative pathological findings of the elderly patients with pulmonary GGO receiving surgery in our hospital from 2017 to 2019 were retrospectively analyzed. The patients were divided into an elderly patient group and a non-elderly patient group based on their age. Results Finally 575 patients were included in the study. There were 281 elderly patients, including 83 males and 198 females, with an average age of (67.0±5.3) years. There were 294 non-elderly patients, including 88 males and 206 females, with an average age of (49.1±7.3) years. Compared with the non-elderly patients, elderly GGO patients showed the following distinct clinical features: long observation time for lesions (P=0.001), high proportion of rough edges of GGO (P<0.001), significant pleural signs (P＜0.001) and bronchial signs (P＜0.001), and high proportion of type Ⅱ-Ⅳ GGO (P<0.001), lobectomy type (P=0.013), and invasive lesions reported in postoperative pathology (P<0.001). There was no statistical difference in the average hospital stay between the two groups (P=0.106). Multivariate logistic regression analysis showed that GGO diameter and GGO type were the main factors affecting the operation. Observation time, GGO diameter, GGO type and pleural signs were the main influencing factors for postoperative pathological infiltrative lesions. The cut-off value of GGO diameter in predicting infiltrating lesions was 10.5 mm in the elderly patients group. Conclusion The size and type of GGO are important factors in predicting invasive lesions and selecting surgical methods. Elderly patients with radiographic manifestations of type Ⅱ-Ⅳ GGO lesions with a diameter greater than 10.5 mm should be closely followed up.
