ABSTRACT
Objective:To observe the effect of Tangtong formula on the expression of autophagy pathway proteins PI3K, Akt and mTOR in sciatic nerve of DPN rats, and to explore its mechanism. Methods:There were 60 male SD rats, 15 of which were randomly selected as the normal group, and the other rats were used to establish DPN model with STZ + ischemia-reperfusion method. Then they were divided into model group, Tangtong formula low-dose group and Tangtong formula high-dose group, with 15 rats in each group with random number table method. 36.67 g/kg Tangtong formula was administered by gavage in the high-dose group and 18.33 g/kg Tangtong formula was administered by gavage in the low-dose group, once a day. After 8 weeks of continuous gavage, the conduction velocity of sciatic nerve was detected. The mRNA and protein expression levels of PI3K, Akt and mTOR were detected by PCR and Western blot. The structure of sciatic nerve fibers was observed by HE staining. Results:Compared with the model group, the motor nerve conduction velocity, sensory nerve conduction velocity, muscle compound action potential and sensory nerve action potential in the low-dose Tangtong formula group and high-dose Tangtong formula group were increased ( P<0.05). The expression of PI3K mRNA(6.05±0.18, 3.36±0.29 vs. 11.57±1.93), Akt mRNA(1.26±0.13, 0.64±0.04 vs. 1.86±0.06), mTOR mRNA(1.82±0.11, 0.92±0.06 vs. 2.68±0.18) of sciatic nerve in rats of the low-dose and high-dose group were increased ( P<0.05). The expression of PI3K(0.40±0.00, 0.19±0.02 vs. 0.61±0.03), Akt(0.64±0.02, 0.45±0.01 vs. 0.83±0.02), mTOR(0.17±0.01, 0.09±0.00 vs. 0.34±0.01)of sciatic nerve in rats of the low-dose and high-dose group were increased ( P<0.05). The model group's nerve fibers were loose and swollen, myelin sheath became thin, and the axis Atresia, the neuromorphology of the low-dose and high-dose group tended to be normal, and the morphology of myelin sheath and axon were better. Conclusions:Tangtong formula could improve the conduction velocity and potential amplitude of sciatic nerve in DPN rats, reduce nerve injury and demyelinating changes, improve axon morphology and protect nerve fiber structure. Its mechanism might be related to activating PI3K/Akt/mTOR signal pathway and inhibiting excessive autophagy.
ABSTRACT
ObjectiveTo observe the effect of aerobic exercise on core symptoms and executive function in children with attention deficit hyperactivity disorder (ADHD). MethodsFrom June, 2020 to December, 2021, 64 children with ADHD at outpatient in Dushu Lake Hospital were randomly divided into control group (n = 32) and observation group (n = 32). The control group sat down and watched the cartoon for 20 minutes, and the observation group performed cycling exercise while watching the cartoon, for twelve weeks. The core symptoms were assessed with Conners Parent Symptom Questionnaire (PSQ), while the inhibition, conversion and refresh functions were assessed with the psychological test software E-Prime 2.0 system. ResultsAfter twelve weeks of treatment, the PSQ factor scores decreased in the observation group (t > 4.775, P < 0.001), and were lower than that of the the control group (t > 3.184, P < 0.001). The response time and accuracy of inhibition, conversion, and refresh functions decreased in the observation group (t > 2.259, P < 0.05), and were lower than that of the control group (t > 2.007, P < 0.05). ConclusionAerobic exercise could reduce the core symptoms of poor attention and hyperactivity impulsivity, and improve the executive functioning in children with ADHD.

Objective:To explore the risk factors of thyroid nodules in diabetic patients and its correlation with Traditional Chinese Medicine (TCM) constitution.Methods:A Total of 213 cases of diabetic patients in Guang’anmen Hospital and Tangshan Hospital from January 2019 to August 2020 were choosen to do the questionnaire, with containly symptom and constitution. The patients were divided into diabetes with thyroid nodules group and diabetes without thyroid nodules group according to whether thyroid nodules were combined. We compared the clinical data characteristics of 2 groups, and used multi-factor logistic regression model to analyze the risk factors of diabetic patients with thyroid nodules and their correlation with TCM constitutions. Results:Diabetes patients aged from 50-80 years old [ OR=2.949, 95% CI (1.266-6.714)], females [ OR=3.736, 95% CI (1.823-1.541)], diabetes duration≥15 years [ OR=1.558, 95% CI (1.623-1.585)], elevated HbA1c [ OR=5.862, 95% CI (1.418-23.629)], elevated VLDL [ OR=2.851, 95% CI (1.597-6.824)], frequent insomnia [ OR=1.970, 95% CI (1.315-3.395)], Qi stagnation [ OR=4.357, 95% CI (2.634-8.377)], blood stasis [ OR=4.420, 95% CI (1.874-15.258)] are more likely to suffer from thyroid nodules ( P<0.05). Conclusion:Diabetic patients aged from 50-80 years old, females, diabetes duration≥15 years, elevated HbA1c, family history of thyroid nodules, frequent insomnia, and mood swings are more likely to develop thyroid nodules; qi stagnation and blood stasis are dangerous constitutions for diabetic patients with thyroid nodules.
ABSTRACT
Objective:To explore the effect of combining repetitive transcranial magnetic stimulation (rTMS) with constraint-induced movement therapy (CIMT) in rehabilitating the upper limb functioning of children with hemiplegic cerebral palsy.Methods:Sixty children with hemiplegic cerebral palsy were recruited and randomly divided into a control group ( n=30) and an experimental group ( n=30). Both groups were given conventional rehabilitation therapy and intensive one-to-one CIMT of the affected hand for 30 minutes 5 times a week for 4 successive weeks. The healthy hand was immobilized in a hand cushion for 3 hours. The experimental group was additionally provided with 20 minutes of rTMS at 1.0Hz, 5 times a week for the same 4 weeks. Before and after the treatment, both groups were evaluated using the Peabody Developmental Motor Scales (PDMS-2 FM) and an upper extremities function test (UEFT). Results:After 4 weeks of treatment there was significant improvement in both groups with regard to the average PDMS-2 FM and UEFT scores. The improvement in the experimental group was significantly better.Conclusions:rTMS combined with CIMT can effectively improve upper limb motor function and promote the fine motor development of children with hemiplegic cerebral palsy.

ABSTRACT
@#Objective To investigate the effects of Chinese herb formula Tangtongfang by bathing the affected feet of patients with diabetic peripheral neuropathy (DPN) in the pattern of Qi deficiency and blood stasis. Methods A parallel, randomized, controlled clinical research was performed. 70 diabetics in the inpatient and outpatient divisions of the Department of Endocrinology, Guanganmen Hospital, from January 2005 to October 2007 were investigated. They were divided randomly into two groups, treatment group and control group, 35 cases in each group. Before study, there were no statistic differences between the two groups, including gender, age, course of diabetes mellitus(DM), course of DPN, blood glucose (including fasting blood glucose and postprandial blood glucose), traditional Chinese medicine(TCM) symptom scores and nerve conduction velocity (NCV). The treatment group were treated with Tangtongfang bathing and the control group were treated with warm water bathing. Each group was also administered Vitamin B1 20 mg, t.i.d and Vitamin B6 20 mg, t.i.d respectively. All patients were keeping their routine treatment and diabetic care to control their blood glucose, such as diets, practices and drugs. Clinical symptoms and electrophysiological tests in diabetic peripheral neuropathy syndrome were investigated. The period of treatment was 8 weeks.Results After study, 9 cases retreated from this clinical trial totally, 4 cases in the treatment group whereas 5 in the control group. Among 4 common single symptoms, coolness feeling of the feet of diabetic patients was significantly improved (P<0.05) after bathed with Tangtongfang. The change of TCM symptom scores and tibialis NCV was significantly improved (P＜0.001, P<0.05) in the treatment group. The improvement ratio was 45.2% and 61.3% in the treatment group, while was 10% and 3.3% in the control group. In each group there was no statistical difference between pre-and post-study with blood test, urine test, blood ALT, blood BUN and Cr, ECG examination (P>0.05). No adverse event was observed in each group.Conclusion Tangtongfang bathing improved several symptoms of patients suffering from DPN, especially the symptom of coolness feeling of the patients' feet. No adverse event was observed. This result showed that Tangtongfang bathing was worthy of using as a safe agent in treatment of DPN.
