This paper reviews the published articles of recent years on the application of deep learning methods in automatic localization of acupoint, and summarizes it from 3 key links, i.e. the dataset construction, the neural network model design, and the accuracy evaluation of acupoint localization. The significant progress has been obtained in the field of deep learning for acupoint localization, but the scale of acupoint detection needs to be expanded and the precision, the generalization ability, and the real-time performance of the model be advanced. The future research should focus on the support of standardized datasets, and the integration of 3D modeling and multimodal data fusion, so as to increase the accuracy and strengthen the personalization of acupoint localization.

Objective:To compare the surface electromyography characteristics of essential tremor (ET), Parkinson′s disease (PD) and essential tremor-Parkinson′s disease syndrome (ET-PD).Methods:A total of 74 patients [ET group ( n=23), PD group ( n=30), and ET-PD group ( n=21)] admitted to the Parkinson′s and Movement Disorders Center of the Department of Neurology of Xuanwu Hospital from August 2020 to December 2023 were enrolled, and results of their bilateral upper limbs surface electromyography (sEMG) were collected. sEMG activities were analyzed offline. Power spectral analysis was performed to explore the sEMG activities. One-way analysis of variance and chi-square test were used to compare the differences of electrophysiological parameters. Results:For the ET group characterized by postural tremor, the frequency was (6.06±0.68) Hz, the amplitude was (1 200.91±360.69) μV, the proportion of alternating contractions was 30.4% (7/23), and the proportion of harmonic resonances was 34.8% (8/23). For the PD group characterized by rest tremor, the frequency was (4.81±0.61) Hz, the amplitude was (1 057.40±354.52) μV, the proportion of alternating contractions was 73.3% (22/30), and the proportion of harmonic resonances was 70.0% (21/30). For the ET-PD group in rest and postural state respectively, the frequencies were (5.04±0.44) Hz and (5.80±0.47) Hz, the amplitudes were (1 026.05±191.90) μV and (1 196.67±212.12) μV, the proportions of alternating contractions were 52.4% (11/21) and 38.1% (8/21), and the proportions of harmonic resonances were 52.4% (11/21) and 33.3% (7/21). Analysis of variance revealed that tremor frequencies for the PD group and the ET-PD group in rest state were lower than the ET group and the ET-PD group in postural state ( F=27.439, P<0.001). The proportion of alternating contractions for the PD group was higher than the ET group ( χ 2=9.669, P=0.002) and the ET-PD group in postural state ( χ 2=6.333, P=0.012). The proportion of harmonic resonances for the PD group was higher than the ET group ( χ 2=6.517, P=0.011) and the ET-PD group in postural state ( χ 2=6.708, P=0.010). No statistically significant differences were found for tremor amplitudes among all the groups ( F=2.143, P=0.100). Conclusions:ET is characterized by postural tremors, with a higher frequency and a lower alternating contractions and harmonic resonances. PD is characterized by rest tremors, with a lower frequency and a higher alternating contractions and harmonic resonances. The parameters of ET-PD are between ET and PD, which provide objective evidences for differential diagnosis of tremors.

Objective To comprehensively evaluate the prevalence of and influencing factors for low-level viraemia(LLV)in Chinese patients receiving antiviral therapy for human immunodeficiency virus(HIV)infection through systematic review and Meta-analysis.Methods Cochrane Library,Web of Science,Embase,PubMed,China Bio-medicine(CBM),VIP,China National Knowledge Infrastructure(CNKI),and Wanfang Data were systematically retrieved.Retrieval time was from the establishment of the database to February 2024.Literatures related to the prevalence of LLV in patients receiving antiviral therapy for HIV infection were retrieved using combination of key-words and free words.Stata 16.0 software was used for Meta-analysis.Random effects model was adopted to calcu-late the combined prevalence and its 95％confidence interval.Results A total of 15 papers were included in analy-sis,involving 191 212 specimens.Meta-analysis random effects model showed that the prevalence of LLV in Chinese patients receiving antiviral therapy for HIV infection was 13.00％(95％CI:7.82％-19.24％).Subgroup analysis showed that cross-sectional studies,northern regions,males,age ≥50 years,heterosexual transmission routes,baseline CD4+T lymphocyte count＜200 cells/μL,and patients who had ever changed therapy regimens had higher LLV prevalence.Conclusion The prevalence of LLV in patients receiving antiviral therapy for HIV infection is re-latively higher.Attention should be paid to such high-risk population,and appropriate antiviral therapy schemes should be selected as early as possible.Timely intervention is necessary when LLV occurs.

Objective To establish an online quantitative analysis model for moisture content assay of hydroxychloroquine sulfate particles by near infrared (NIR) spectroscopy. Methods The NIR spectra were collected in real time when the material particles were dried in the fluidized bed. Meanwhile the water content of the particles was measured with the standard moisture tester. The multiplicative signal correction (MSC) and first derivative followed by Karl Norris smoothing were used for spectra pretreatment. Two spectral range (4 935−5 336 cm⁻¹ and 6 911−7 297 cm⁻¹) were selected for the quantitative model with the partial least squares (PLS) regression. Results The quantitative calibration model had good correlation coefficients with Rc value=0.952 9 and Rp value=0.936 6. The root mean square error of calibration (RMSEC) was 0.408 and the root mean square error of prediction error (RMSEP) was 0.435. The ratio of standard deviation of validation set to prediction standard deviation (RPD) was 5.18. There was no significant difference between the predicted value and the reference value by t test when the established model was applied in large-scale production. Conclusion The online model established for monitoring water content has high accuracy and stability, which can be applied in industrial scale process to monitor the particle moisture in real time.

Objective:To summarize the experience and technical difficulties of complete thoracoscopic lobectomy(segmental) in the treatment of congenital pulmonary airway malformation in children.Methods:The clinical data, surgical videos and follow-up results of 38 children suffering from congenital pulmonary airway malformation and underwent complete thoracoscopic lobectomy in Children′s Hospital of Fudan University Xiamen Branch from January 2017 to December 2019 were retrospectively analyzed.A statistical comparisons of operative time, intraoperative blood loss, postoperative pain (the first time of getting out of bed), incision length and postoperative pulmonary complications were made between 28 children who underwent the total thoracoscopic lobectomy and 21 children who accepted open surgical lobectomy before January 2017 in Children′s Hospital of Fudan University Xiamen Branch.Results:Thirty-eight children with congenital pulmonary airway malformation were successfully operated by complete thoracoscopy.There were 28 lobectomies, 6 segmental lobectomies and 4 wedge lobectomies.Postoperative follow-up was conducted for more than 3 months, and no serious surgical complications occurred.Chest radiograph of 2 children with the right lower lobectomy at 48 hours after surgery had the elevation of the right diaphragm (2-3 intercostal), and it returned to normal 3 months after surgery.The CT review of 1 child with pulmonary wedge resection 1 month after surgery displayed a little residual lesion.Thoracoscopic lobectomy was significantly different from open surgery in terms of incision length[(2.0±0.5) cm vs. (10.0±0.5) cm], postoperative pain (the first time of getting out of bed)[(24.0±2.0) h vs. (48.0±1.5) h] and pulmonary complications (0 vs. 5 cases). The operative time of single lung ventilation was remarkably different from that of double lung ventilation in thoracoscopic lobectomy[(96.0±6.0) min vs. (118.0±7.0) min, t=106.501, P<0.001]. Compared with thoracoscopic lobectomy, thoracoscopic pulmonary segmentectomy has a long time and a large amount of blood loss. Conclusions:Complete thoracoscopic lobectomy (segmental) is the first choice for the treatment of congenital pulmonary airway malformation in children, with clear operative field, little trauma, less postoperative pain, quick recovery and fewer respiratory complications.Single-lung ventilation is beneficial for surgical completion.

Objective To explore the factors related to the consumption of sugar-sweetened beverages (SSB) among middle school students in four provinces (municipality) in China.Methods A total of 3 469 middle school students were recruited from the Children health cohort in eight counties within the four provinces (municipality).We collected information regarding demography,lifestyle,and family and school situation as well as the consumption frequency of SSB in the previous week.High SSB consumption was defined as "positive" if the frequency was once a day or more.Mean consumption time was calculated,and then logistic regressions were performed to explore the factors influencing SSB consumption.Results Prevalence of high SSB consumption was 11.18％ among the subjects of the eight counties,and the consumption frequency of SSB was 0.21 times per day.Multivariate logistic regression analysis revealed that the following factors were associated with high consumption of SSB:higher grade,rural region,male gender,physical exercise,habit of eating snacks,eating out,and fast-food consumption (P＜0.01).Factors influencing high SSB consumption were not completely equal between genders:physical exercise at school was associated with high SSB consumption only in female students (P＜0.01),while higher grade and eating out in the past week were associated with high SSB consumption only in male students (P＜0.05).Conclusion Factors associated with high SSB consumption among middle school students included grade,region,physical exercise at school,snack consumption,eating out,and fast-food consumption.These factors differed between genders.Intervention programs addressing these factors may be beneficial in reducing SSB consumption in middle school students.

To explore the evaluation method of evidence body for acupuncture and moxibustion clinical practice guidelines (CPGs), and to provide methodological support for the development of acupuncture and moxibustion CPGs and to promote the establishment and application of acupuncture and moxibustion standard. Based on the academic characteristics of TCM acupuncture, the stratified evidence evaluation method was proposed. Firstly, evidences were collected from the ancient literature, modern literature and clinical experience, and were scientifically distinguished and evaluated. Secondly, all the evidences were integrated as body of evidence by analytic hierarchy process (AHP). Lastly, based on the general index (GI), the clinical recommendations for acupuncture were proposed. Based on the stratified evidence evaluation method, acupuncture and moxibustion CPGs were developed in a more scientific and objectiveway with the comprehensive and sufficient evidences.

The current clinical efficacy evaluation system and evaluation methods of acupuncture have several limitations, and the application status is not optimistic. According to long-term observation, minimum clinically important difference (MCID) is consistent with the characteristics of clinical acupuncture, and has objective quanti- tative standard and wide applicability. Incorporating MCID into acupuncture clinical efficacy evaluation of tradition- al Chinese medicine can truly reflect the clinical effect of acupuncture and improve the disadvantages and shortcom- ings of acupuncture clinical evaluation, which could provide certain reference for building clinical efficacy evaluation system featured with TCM.
