This study examined the effects of combined administration of tyrosine, lecithin, L-glutamine and L-5-hydroxytryptophan (5-HTP) on heroin withdrawal syndromes and mental symptoms in detoxified heroin addicts. In the cluster-randomized placebo-controlled trial, 83 detoxified heroin addicts were recruited from a detoxification treatment center in Wuhan, China. Patients in the intervention group (n=41) were given the combined treatment with tyrosine, lecithin, L-glutamine and 5-HTP and those in the control group (n=42) were administered the placebo. The sleep status and the withdrawal symptoms were observed daily throughout the study, and the mood states were monitored pre- and post-intervention. The results showed that the insomnia and withdrawal scores were significantly improved over time in participants in the intervention group as compared with those in the control group. A greater reduction in tension-anxiety, depression-dejection, anger-hostility, fatigue-inertia and total mood disturbance, and a greater increase in their vigor-activity symptoms were found at day 6 in the intervention group than in the control group (all P<0.05). It was concluded that the neurotransmitter-precursor-supplement intervention is effective in alleviating the withdrawal and mood symptoms and it may become a supplementary method for patients' recovery from heroin addiction.

Objective To observe the effects of electro-acupuncture (EA) at “Weizhong” (BL40) on expressions of Fas and FasL in rat models with lumbar disc degeneration; To discuss its mechanism of action.MethodsThirty SD rats were randomly divided into sham-operationgroup, model group and EA group, with 10 rats in each group. The sham-operation group was treated with sham operation to incide local skin; the model and EA groups established rat model of lumbar disc degeneration by puncturing the annulus fibrosus. Four weeks after modeling, rats in the sham-operation and model groups received fixed treatment under identical condition, and rats in the EA group were treated with EA at “Weizhong” (BL40) in 20 minutes, once a day, for 4 weeks. After treatment, Western blot and RT-PCR technology were used to test the protein and mRNA expression levels of Fas and FasL.ResultsThe expressions of Fas and FasL in the model group were higher than those in the sham-operation group (P<0.05); protein and mRNA expression levels of Fas and FasL in the EA group were lower than those in the model group (P<0.05). ConclusionEA at “Weizhong” (BL40) can reduce the expressions of Fas and FasL to inhibit the development of lumbar disc degeneration.

Objective:
To explore the relationship among jogging risk perception, jogging risk behavior and the incidence of jogging risk, so as to provide a feasible way to reduce the risk of college students extracurricular jogging exercise.
Methods:
The method of convenience sampling was used to conduct a follow up survey among 470 college students at a university in Beijing participating in extracurricular jogging exercise and the sports world campus app was used to record and monitor jogging exercise. During the tracking period, the jogging related information was counted once a month, a total of 6 times. At the same time, three questionnaires were distributed in three stages to collect relevant information. SPSS 26.0 was used for the descriptive analysis, and AMOS 22.0 was used for correlational analysis.
Results:
The risk rate of extracurricular jogging exercise of college students during the past academic year was 71.06 %, score of knowledge on jogging risk was(3.68±0.59), was (3.25±0.91)for jogging injury, and was( 3.23± 0.96)for jogging related disease. Significant negative correlation between college students jogging risk perception and jogging risk behavior ( r =-0.34), negative correlation between jogging risk perception and the incidence of jogging injuries ( r =-0.27), and positive correlation between jogging risk behavior and the incidence of jogging injuries ( r =0.28) were observed( P <0.01). PE(physical education) class was the main way of obtaining the knowledge about jogging risks among college students(43.40%).
Conclusion
College students show high vulnerability for extracurricular jogging related risks, and low level of perception of jogging risks and jogging injuries. Relevant measures need to be taken to improve the cognitive level of running risk among college students, so as to reduce the incidence of running risk.

Objective:
To investigate the effects of two nanotopographies of ultraviolet (UV)-treated titanium surface on macrophage biological behaviour and inflammatory cytokines secretion, and to provide basis for clinical application of UV-treatment in dental implant modification.
Methods:
Titanium disks were allocated into two groups. Samples in one group were acid-etched in hydrofluoric acid (Acid Ti group), and those in the other group were acid-etched and anodized (Anodization group) to form two nanotopographies respectively. The surface morphology was evaluated by field-emission scanning electron microscopy (FE-SEM). The samples were stored in the dark for 8 weeks. Thirteen samples from each group were exposed to UV-irradiation for 48 h (Acid Ti+UV group and Anodization+UV group), UV-untreated samples from Acid Ti and Anodization groups served as control. Hydrophilicity of samples was measured using contact angle measuring device. After 4, 24 and 72 h of incubation, macrophage cell adhesion and proliferation were conducted using cell counting kit-8. Cytokine/chemokine secretions [tumor necrosis factor-α (TNF-α), monocyte chemotactic protein-1 (MCP-1) and macrophage inflammatory protein-1α (MIP-1α)] were measured from cell culture supernatants at 24 and 72 h using magnetic luminex assay. Cell morphology was examined using FE-SEM after 2 h of incubation.
Results:
Micropitted/nanopillar and micropitted/nanotubular topographies were observed in Acid Ti group and Anodization group respectively. Contact angles in Acid Ti+UV and Anodization+UV groups (20.2°±2.8° and 0.0°±0.0°) were significantly smaller than those in the Acid Ti and Anodization groups (

Objective To study the role of ubiquitin proteasome pathway in Du Meridian moxibustion for skeletal muscle aging. Methods A total of 30 Sprague-Dawley rats were randomly separated into control group (n=10), model group (n=10) and moxibustion group (n=10). The model group and the moxibustion group were subcutaneously injected D-galactose 125 mg/kg daily for six weeks, while the control group was injected the same volume of saline. Then the moxibustion group was cauterized on Du Meridian 20 minutes a day for 20 days. The expression of ubiquitin, muscle RING finger 1 (MuRF1) and muscle atrophy F-box (MAFbx) in erector spinae were tested with Western blotting. Results The expression of ubiquitin, MuRF1 and MAFbx increased in the model group compared with that of the control group (P<0.05), decreased in the moxibustion group compared with that of the model group (P<0.05).Conclusion The Du Meridian moxibustion may regulate ubiquitin proteasome pathway to inhibit the degradation of protein, and delay muscular atrophy.

Objective To explore the effect of electroacupuncture at Weizhong (BL40) acupoint on the expression of Bcl-xL and Bax in rats with lumbar disc degeneration. Methods Thirty male adult Sprague-Dawley rats were randomly divided into sham-operated group (n= 10), model group (n=10), and electroacupuncture group (n=10). The lumbar disc degeneration model was established by puncturing the annulus fibrosis in the model group and electroacupuncture group. One month after modeling, the electroacupuncture group was electroacupunctured at Weizhong acupoint for four weeks. HE staining was used to observe the pathological changes. Immunohistochemical staining was used to observe the expression of Bax in the lumbar disc tissue. Western blotting was used to detect the expression of Bcl-xL and Bax protein. Results HE staining showed that the degrees of lumbar disc degeneration from light to severe was ranged as: the sham-operated group, the electroacupuncture group and the model group. The expression of Bcl-xL was lower (P<0.05), and the expression of Bax was higher (P<0.01) in the model group than in the sham-operated group, which was opposite (P<0.01) in the electroacupuncture group than in the model group. Conclusion Electroacuponcture at Weizhong may upregulate the expression of Bcl-xL and downregulate the expression of Bax in rats with lumbar disc degeneration.
