The information concerning the treatment of Bi condition in 93 ancient medical books has been statistically analyzed through computer. The results showed that there were a total of 149 items of literature and 102 acupoints (276 times in frequency) in association with Bi condition. The common acupoints are Hegu (LI 4), Zusanli (ST 36), Fengshi (GB 31), diseased foci, Quchi (LI 11), Weizhong (BL 40), Yanglingquan (GB 34), Yangfu (GB 38), et al. The common meridians are Gallbladder Meridian,Bladder Meridian, Large Intestine Meridian, Stomach Meridian, Lung Meridian, Liver Meridian and Triple Energizer Meridian. The common parts are the lateral aspect of leg, arm, and foot, the medial aspect of foot, the lateral aspect of hand, the medial aspect of arm, and head. The common acupuncture techniques and their frequencies are moxibustion (54), needling (9), blood-letting (9), fire needling (2), ironing (2) and compression (1). Statistical analysis on the above information showed in the ancient times in treating Bi condition with acupuncture, selecting acupoints are according to meridian distribution, the body parts and syndrome differentiation.

5.Tracking observation of fine motor development in children aged 6-8 with attention deficit hyperactivity disorder
Chinese Journal of School Health 2024;45(6):831-834
Objective:
To examine the developmental trajectory of fine motor ability in schoolage children with attention deficit hyperactivity disorder (ADHD) for two years, so as to provide scientific evidence to promote motor development in ADHD children.
Methods:
From April to June 2019, 31 children aged 6-8 years old were selected from a public elementary school. They were diagnosed with ADHD by two psychiatric professionals according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) criteria. Additionally, 31 typical developmental children, matched for age, sex and IQ with the ADHD group, were recruited as the control group. Fine motor ability was assessed with tasks of hand manual dexterity in Movement Assessment Battery for Children-2 (MACB-2), and a followup assessment was conducted from April to June 2021. The development changes of fine motor ability between two groups of children were compared by using t test and repeated measures analysis of variance.
Results:
Between baseline and followup periods after two years, the total score of hand fine motor in the ADHD group did not show significant improvement (7.4±3.0, 8.0±3.4; t=-1.05, P>0.05), while there was a small effect size improvement in typically developing control group (9.5±2.1, 10.5±2.4; t=-2.12, effect size=0.38, P<0.05). Followup after two years, coin/peg throwing scores with dominant hand improved between ADHD group and control group (7.0±3.3, 9.5±3.2; 8.4±2.8, 11.6±1.6) (t=-3.74, -6.33, P<0.01; effect size=0.67, 1.14), with a smaller improvement in the ADHD group. The score for threading beads/threads decreased in between ADHD group and control group (7.9±2.4, 5.8±3.1; 9.2±1.1, 8.2±1.9) (t=3.89, 2.78, P<0.01; effect size=0.70, 0.50), with a greater decrease in the ADHD group.
Conclusions
The development speed of fine motor ability in children with ADHD aged 6-8 is slow and continues to lag behind normal developmental children. Fine motor development in children with ADHD should be closely monitored, and targeted interventions should be implemented when necessary.

Objective To evaluate the regulatory effect of the adaptor related protein complex 2 subunit μ1(AP2M1)on proliferation and invasion of diffuse large B-cell lymphoma(DLBCL).Methods Human diffuse large B-cell lymphoma cell line OCI-LY8 was aliquoted into control group,NC-shRNA group,AP2M1-shRNA group,NC-LV group,and AP2M1-LV group.Lipofectamine 2000 was used for cell transfection.Cell proliferation was detected by tetramethylazolium salt(MTT)method,apoptosis was detected by flow cytometry and cell migration and invasion were detected by Transwell assay.The protein expression of AP2M1,epidermal growth factor receptor(EGFR),p-phosphatidylinositol 3 kinase(PI3K),PI3K,p-protein kinase B(Akt)and AKT was detec-ted by Western blot.Results Compared with control group,the relative expression of AP2M1 mRNA and protein in the AP2M1-shRNA group was decreased(P<0.05).The relative cell viability was increased(P<0.05).The cell apoptosis rate was decreased(P<0.05).The counting number of migrating and invading cells was in-creased(P<0.05).The relative expression level of EGFR protein and the phosphorylation level of PI3K and AKT were increased(P<0.05).Compared with Control group,the expression of AP2M1 mRNA and protein relative ex-pression level in AP2M1-LV group was increased(P<0.05).The relative cell viability was decreased(P<0.05).The cell apoptosis rate was increased(P<0.05).The number of migrating and invading cells was decreased(P<0.05).The relative expression level of EGFR protein and the phosphorylation level of PI3K and AKT were all decreased(P<0.05).Conclusions The over-expression of AP2M1 partially inhibits the proliferation and invasion of DLBCL cells by inhibiting the EGFR/PI3K/AKT signaling pathway.

Objective To observe the electromyography characteristics of children's handwriting with attention deficit hyperactivity disorder(ADHD),and explore its electrophysiological mechanism,so as to provide an objective basis for developing non-pharmacological treatment for such children.Methods Between September 2021 and April 2022,29 ADHD children were recruited from an ordinary public primary school and the psychiatric clinic of a class-3 grade-A hospital in Beijing.Among them,25 were boys and 4 were girls,with an average age of 8.21±1.78 years.Meanwhile,23 male and 5 fe-male healthy counterparts were selected with the age gap no more than 6 months.The Delsys wireless surface EMG system was used to collect the electromyographic signals of the abductor pollicis breve,the first dorsal interosseous muscle,the flexor radial carpi motor and the extensor finger muscles dur-ing their writing tasks such as tracing trajectories,writing Arabic numerals 0-9,26 small and capital English letters,Chinese characters one to ten and"Yong".The percentage of the averaged electromyog-raphy(AEMG)of a muscle in the sum value of all measured muscles,and the coefficient of differ-ence were selected to evaluate the muscle contribution rate and the consistency of exertion,respective-ly.Moreover,the independent sample t-test was employed to compare the two different groups with the significance set at α=0.05.Results There was a significant difference in the muscle contribution of abductor pollicis breve and first dorsal interosseous muscles when writing Arabic numerals and that of abductor pollicis breve muscles when writing Chinese characters between ADHD children(27.29%,25.58%and 27.53%)and their healthy counterparts(42.87%,19.96%and 37.13%)(P<0.05).Most muscle differentiation coefficients of ADHD children were higher than 100%,with that of the domi-nant hand radial wrist flexor muscle reaching 270%in the trajectory tracing task.Conclusion Accord-ing to the characteristics of EMG signals,school-age ADHD children show an immature writing pat-tern,including poor stability of writing-related muscles,insufficient control of small finger muscle groups,poor control of hand coordination,and insufficient muscle inhibition of non-dominant hand.It is recommended to conduct the electromyoelectric assessment of handwriting movements in ADHD chil-dren,so as to carry out targeted intervention at an early stage.
