The paper summarizes the authorized invention patents, device registration and the relevant published articles of acupuncture medical devices of TCM in recent 5 years, and analyzes the current status and challenges in this field. It is discovered that the optimization and substitution in diagnosis and treatment of acupuncture are involved in the development of acupuncture medical devices. The technology application of these devices are composed of traditional and emerging engineering technologies; and the theoretical guidance for their development requires the integration of traditional acupuncture principles with modern medical theories. The development of acupuncture medical devices highlights the characteristics of multidimensional integration, treatment for specific ailments, portability and wearability, painlessness and non-invasion, precision and personalization, as well as intelligent automation. Upon analysis, it is shown that in the development and product transformation of acupuncture medical devices in recent years, the theoretical principles of acupuncture of TCM have not been fully utilized yet, the transformation of patented product is low, the clinical evidence of product is insufficient, and the market competitiveness needs improvement. In the future, The theoretic guidance of acupuncture of TCM should be enhanced in the development of acupuncture medical devices, a production-education- research model with the combination of medicine and engineering be constructed, clinical verification of product be emphasized, and product development paradigms be advanced, so as to meet the demands of the medical market.

The minimal persistent inflammation(MPI)of allergic rhinitis(AR)is asymptomatic inflammation that occurs locally in the nasal mucosa after exposure to low doses of allergens.With the study of MPI,researchers have realized that this local sub-clinical inflammation in patients with AR not only causes chronic damage to the nasal mucosa,but also increases the hypersensitivity and hyperresponsiveness of allergic airway disease.The concept of MPI has changed our strategy for the treatment of AR,which re-quires that we should not only intervene in the symptomatic exacerbation period,but also intervene in the asymptomatic MPI period.This article systematically reviews the immunological mechanism,adverse effects,and treatment strategies of the MPI,to provide bet-ter treatment for the MPI of AR and reduce the recurrence of AR.

Objective:To evaluate the clinical efficacy and safety of stereotactic surgery in patients with refractory mental disorders.Methods:A retrospective analysis was performed; clinical data, postoperative complications and medication intake of 149 patients with refractory mental disorders accepted stereotactic surgery in Department of Neurosurgery, People's Hospital, Wuhan University from August 2019 to December 2023 were collected. Outcomes were assessed at 1, 6, 12, and 24 months after surgery by Clinical Global Impression-Global Improvement (CGI-GI). Before and 1, 6, and 12 months after surgery, severities were assessed by Clinical Global Impression-Severity of Illness (CGI-SI); cognition was assessed by Montreal Cognitive Assessment (MoCA); positive and negative symptoms were evaluated by Positive and Negative Symptom Scale (PANSS); psychotic symptoms were evaluated by Brief Psychiatric Rating Scale (BPRS) and Symptom Checklist 90 (SCL-90); obsessive-compulsive symptoms, depressive symptoms, anxiety symptoms and manic symptoms were assessed by Yale-Brown Obsessive-Compulsive Symptoms Scale (Y-BOCS), Beck Depression Inventory (BDI)-II, Beck Anxiety Inventory (BAI), and Young Mania Rating Scale (YMRS), respectively; social functioning and quality of survival were evaluated by Social Disability Screening Schedule (SDSS) and World Health Organization Quality of Life-Bref Form (WHOQOL-BREF).Results:(1) Increased sleep was noted in 47 patients and fatigue in 38 patients within 1 week after surgery. Behavioral laziness and emotional apathy were still presented at 1 month after surgery in 6 patients, and complications disappeared in the rest patients. Mildly reduced initiative was presented at 12 months after surgery in 5 patients. (2) CGI-GI indicated that 149 patients were followed up 1 month after surgery with an overall efficiency of 85.90%; 135 patients were followed up at 6 months after surgery with an overall efficiency of 83.21%, 106 patients were followed up at 12 months after surgery with an overall efficiency of 79.24%, and 63 patients were followed up at 24 months after surgery with an overall efficiency of 80.95%. (3) Compared with those before surgery, significantly lower BPRS scores, significantly lower PANSS positive, negative, and overall scores, statistically lower BAI, BDI-II, YMRS, and MOAS scores, significantly lower Y-BOCS obsessional thinking, compulsive behavior and total scores, significantly higher WHOQOL-BREF (physical and psychological domains) scores, and significantly lower SDSS and SCL-90 scores were noted in patients at 1, 6, and 12 months after surgery ( P<0.05). (4) At 12 months after surgery, withdrawal drug was noted in 13 patients, reduced drug in 38, same dose in 52, and increased drug in 2 patients. Conclusion:Stereotactic surgery can obviously improve obsession, anxiety, depression, mania and aggression, and modify social functioning and quality of survival in patients with refractory mental disorders, enjoying good safety.

In response to the Opinions of the CPC Central Committee and the State Council on Promoting the Inheritance， Innovation， and Development of traditional Chinese medicine（TCM） and the spirit of the National Conference on TCM， Chinese Association of Chinese Medicine organized experts in Otorhinolaryngology Head and Neck Surgery of traditional Chinese and western medicine to discuss the clinical advantages of TCM and integrated traditional Chinese and western medicine in the treatment of allergic rhinitis （AR） and they reached a basic consensus. In recent years， the prevalence of AR has been on the rise， threatening the quality of life of patients and giving rise to a heavy burden to both the patients and the society. AR is resulted from immune imbalance rather than reduced immunity or hyperimmunity， and the imbalance is similar to the Yin-yang disharmony in TCM. In the treatment of this disease， western medicine features rapid onset. However， it is cost-intensive and causes severe surgical trauma， and the recurrence is common. TCM boasts diverse methods for AR， which can be used in all stages of this disease. It has advantages in controlling symptoms such as nasal congestion， runny nose， or dysosmia in the attack stage， preventing recurrence in the remission stage， and treating refractory AR or steroid-resistant AR. In particular， acupuncture enjoys a reputation in treatment of AR， which has been supported by evidence-based medicine and recommended by guidelines. While treating local symptoms of AR， TCM regulates the psychosomatic conditions， which facilitates chronic disease management and long-term follow-up. We should integrate the advantages of TCM and western medicine， give full play to the unique nonnegligible and irreplaceable advantages of TCM， formulate a comprehensive diagnosis and treatment scheme for learning and promotion， and summarize the research outcomes to promote the theoretical innovation of TCM on AR from the perspective of integrated traditional Chinese and western medicine.

In order to improve medical students' cognition of neurosurgery specialty and clinical practice,and cultivate students' self-learning ability,the model of flipping classroom combined with problem based learning was applied in clinical teaching in our department.The experimental group adopted flip classroom combined with PBL which penetrated the pre-class teaching design,classroom activity design,after-class summary and teaching feedback,while the control group adopted the traditional teaching method.The evaluation results showed that the students in the experimental group had significantly higher scores in-class knowledge and examination results than those in the control group.In addition,students had a high degree of recognition and satisfaction with the newly combined teaching model.The combination of flipped classroom and PBL teaching method could make up their deficiency,complement each other to achieve the best clinical teaching effect and improve students comprehensive ability.Meanwhile it puts forward new requirements for students and teachers,during which teachers need to be fully prepared and update teaching concepts for the sake of fulfilling the mutual promotion of teaching and learning.

Objective To study the clinical significance of Chirp-ASSR and the characteristics of hearing loss patients by ASSR(auditory steady-state responses) under Chirp stimulation.Methods A total of 136 hearing loss children (5～10 years old) with 272 ears were distributed into four groups based on 500 Hz,1 000 Hz,2 000 Hz and 4 000 Hz auditory threshold arithmetic average:20～dB HL,40～dB HL,60～dB HL,and≥80 dB HL groups.To compare the correlation of the PTA and Chirp-ASSR in different frequencies domain through SPSS statistics 19.0 software,the data were used T-test and Pearson analysis.Results ①The group(≥80 dB HL) achieved a statistically significant higher reaction threshold than pure tone threshold.②The correlation index γ'of PTA and Chirp-ASSR showed a decline along with the hearing loss increase;It increased along with the test frequency,there was a significant difference between 500 Hz and 4 000 Hz(P＜0.05).Conclusion Chirp-ASSR is a frequency-specific electrophysiological test method,it could reflect the truthful listening ability,especially in mild,moderate,and severe hearing loss children.

Objective To study the anatomic characteristics and clinical values of the internal auditory artery via the neuroendoscope and microscope.Methods We observed the related microdissection of the internal auditory artery of 15 cadavers through retrosigmoid approach by operative microscope and neuroendoscope,in which 3 cadavers were fresh.Results The internal auditory arteries were observed bilaterally in all specimens (100％).Among them,17 sides (56.7％,17/30) were isolated branch type,9 sides were dual trunk (30％,9/30),and 4 sides were three branches type (13.3％,4/30).The diameter of the vessel at its origin was 0.12～0.28 mm,the average caliber of IAA was 0.22±0.04 mm,the length of IAA ranged from 7.12 to 14.82 mm,and the Mean 10.18± 2.63 mm.The starting-point of IAA was quite variable,13.3％ (4/30) of the IAA origined from the inferior segment of the basilar artery,and 86.7 ％(26/30) of the IAA origined from ACIA.Among them,17 sides (65.4％,17/26) of the IAA origined from the ansa of the inferior cerebellar artery,9 sides (34.6％,9/26) of the IAA origined from the anterior inferior cerebellar artery involved in the inner ear canal.We observed that 73.3 ％(22/30) of the IAA branches were along the ventral side of the vestibulocochlear nerve;26.7 ％(8/30) of the IAA branches were above the nerves.It's easy to identify the IAA and its adjacent structures by various neuroendoscope through various anatomic fissures.Conclusion Most of internal auditory arterys were located anterior and posterior to the facial nerve,the microscope was impossible to see it directly.A thorough identification of the internal auditory artery requires theuse of both surgical microscopy and neuroendoscope.

OBJECTIVETo understood the accuracy of oral fluid-based rapid HIV self-testing among men who have sex with men (MSM) and related factors.

METHODSSurvey was conducted among MSM selected through non-probability sampling to evaluate the quality of their rapid HIV self-testing, and related information was analyzed.

RESULTSThe most MSM were aged 21-30 years (57.0%). Among them, 45.7% had educational level of college or above, 78.5% were unmarried, 59.3% were casual laborers. The overall accuracy rate of oral fluid based self-testing was 95.0%, the handling of"inserting test paper into tube as indicated by arrow on it"had the highest accuracy rate (98.0%), and the handling of"gently upsetting tube for 3 times"had lowest accuracy rate (65.0%); Chi-square analysis showed that educational level, no touch with middle part of test paper, whether reading the instruction carefully, whether understanding the instruction and inserting test paper into tube as indicated by the arrow on it were associated with the accuracy of oral fluid-based rapid HIV self-testing, (P<0.05). Multivariate logistic regression analysis indicated that educational level, no touch with middle part of test paper and understanding instructions were associated with the accuracy of oral fluid-based rapid HIV self-testing.

CONCLUSIONSThe accuracy of oral fluid-based rapid HIV self-testing was high among MSM, the accuracy varied with the educational level of the MSM. Touch with the middle part of test paper or not and understanding the instructions or not might influence the accuracy of the self-testing.

OBJECTIVETo investigate the digit ratio of men who have sex with men (MSM), and the relationship between digit ratio and the partner types of MSM.

METHODSParticipants were required from Yunnan Rainbow Sky, a community organization that specialized in HIV testing, intervention and counseling services for MSM between December 2014 and April 2015. Inclusion criteria of MSM as the following: more than 18 years old; men who have had sex with men; HIV test was negative. Exclusion criteria were as this: those who couldn't attend the research due to disability. Eventually, there were 115 MSM participated in the research. According to the nationality, we adopted 1:1 matched case-control study, and we selected 115 men as control group. According to the partner number of MSM, the MSM were divided into two groups. One group was fixed partner and another was multi-partner. We used a questionnaire to collect the demographic characteristics, knowledge about HIV/AIDS, sexual behaviors during nearly 6 months, sexual orientation, the places where looked for sex partners, sex roles, drug use, preventive services etc. Then, the physical measurements were used to measure the length from second to the fifth finger in MSM group and control group. The results were expressed as nD. The chi-square test was used to compare the demographic differences between MSM group and the control group, and the T-test was used to compare the digit ratio between two groups.

RESULTSAmong 115 MSM, there were 26% (30/115) MSM who had a fixed partner, and there were 74% (85/115) MSM who had multi-partner. The mean values of digit ratio of MSM presented a trend as 2D:3D < 2D:4D < 3D:4D < 2D:5D < 4D:5D < 3D:5D. The right 2D:4D and 2D:5D of MSM were 0.957 7 ± 0.048 1 and 1.229 8 ± 0.083 4, and the mean value was significasntly higher than control group (0.941 4 ± 0.038 0 and 1.204 1 ± 0.069 5, t values were 2.84, 2.54 and P values were 0.005, 0.012). The right 2D:4D of the fixed partner group and multi-partner group among MSM were 0.962 2 ± 0.051 0 and 0.956 1 ± 0.047 3, respectively, and the mean values were significantly higher than control group (t values were 2.98, 2.83; P values were 0.027, 0.015).

CONCLUSIONThe proportion of multi-partner MSM was higher, so MSM at a high risk of being HIV infected. Right 2D:4D could be used as a biomarker of the MSM in Kunming, but couldn't reflect the features of MSM whether he has a fixed partner or has several partners.

OBJECTIVETo analyze the characteristics of risky behaviors among different age groups of HIV positive female sex workers, and to explore the strengthening of their management.

METHODSFrom January to June 2014, 22 814 female sex workers were investigated and tested HIV in 117 sentinel surveillance sites in Yunnan Province, and 181 were confirmed to be HIV antibody positive, who accepted questionnaire surveys. According to the age, the participants were divided into the < 35 years old age group and ≥ 35 years old age group. The demographic characteristics, knowledge about HIV/AIDS and related risk behaviors characteristics of the two groups were obtained via questionnaire surveys among 181 HIV positive female sex workers, and in-depth qualitative interviews were conducted from among 12 HIV positive sex workers.

RESULTSHIV antibody positive rate was 0.8% (181), the age of the 181 subjects were (35.83 ± 9.17) years old, 76 cases (42.0%) were < 35 years old, and 105 cases (58.0%) were ≥ 35 years old. The differences of marital status, workplace class, the last work site among two groups were statistically significant (χ(2) = 20.80, 28.32, 7.83; P < 0.001, P < 0.001, P = 0.020, respectively). Among 181 HIV, the proportion of AIDS awareness was 95.6% (173); the proportion of drug use among ≥ 35 years old age group was 51.4% (54), which was higher than that in < 35 years old age group (34.2%, 26/76) (χ(2) = 5.30, P = 0.021). 96.7% (175) received condom promotion or HIV counseling and testing in the past year. The proportion of continuing to engage in sexual services over 5 years after HIV infection was 48.5% (51/105) and the proportion of receiving antiretroviral treatment was 69.5% (73/105) in ≥ 35 years old age group, which were higher than those in the < 35 age group (30.2% (23/76), 52.6% (40/76); χ(2) = 12.26, 5.36; P = 0.002, 0.021, respectively). In-depth interviews among 12 HIV positive female sex workers found that regular clients, not consistent use of condoms were the main cause of no condom use. Economic and livelihood factors are important reasons for continuing to engage in sexual services among HIV positive sex workers.

CONCLUSIONHIV positive sex workers still have high risk behaviors including continuing to engage in commercial sexual service and no condom use after knowing their HIV infection status, and the proportion of using drugs in the ≥ 35 years old group was higher than that in < 35 years old group.
