ICAM-1 may promote the loss of dopaminergic neurons by regulating inflammation in MPTP-induced Parkinson's disease mouse models.

Parkinson's disease (PD) is a chronic neurodegenerative disease with unclear pathogenesis that involves neuroinflammation and intestinal microbial dysbiosis. Intercellular adhesion molecule-1 (ICAM-1), an inflammatory marker, participates in neuroinflammation during dopaminergic neuronal damage. However, the explicit mechanisms of action of ICAM-1 in PD have not been elucidated. We established a subacute PD mouse model by the intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and observed motor symptoms and gastrointestinal dysfunction in mice. Immunofluorescence was used to examine the survival of dopaminergic neurons, expression of microglial and astrocyte markers, and intestinal tight junction-associated proteins. Then, we use 16 S rRNA sequencing to identify alterations in the microbiota. Our findings revealed that ICAM-1-specific antibody (Ab) treatment relieved behavioural defects, gastrointestinal dysfunction, and dopaminergic neuronal death in MPTP-induced PD mice. Further mechanistic investigations indicated that ICAM-1Ab might suppress neuroinflammation by inhibiting the activation of astrocytes and microglia in the substantia nigra and relieving colon barrier impairment and intestinal inflammation. Furthermore, 16 S rRNA sequencing revealed that the relative abundances of bacterial Firmicutes, Clostridia, and Lachnospiraceae were elevated in the PD mice. However, ICAM-1Ab treatment ameliorated the MPTP-induced disorders in the intestinal microbiota. Collectively, we concluded that the suppressing ICAM-1 might lead to the a significant decrease of inflammation and restore the gut microbial community, thus ameliorating the damage of DA neurons.

Expert consensus on protocol of rehabilitation for COVID-19 patients using framework and approaches of WHO International Family Classifications.

Coronavirus disease 2019 (COVID-19) has widely spread all over the world and the numbers of patients and deaths are increasing. According to the epidemiology, virology, and clinical practice, there are varying degrees of changes in patients, involving the human body structure and function and the activity and participation. Based on the World Health Organization (WHO) International Classification of Functioning, Disability and Health (ICF) and its biopsychosocial model of functioning, we use the WHO Family of International Classifications (WHO-FICs) framework to form an expert consensus on the COVID-19 rehabilitation program, focusing on the diagnosis and evaluation of disease and functioning, and service delivery of rehabilitation, and to establish a standard rehabilitation framework, terminology system, and evaluation and intervention systems based the WHO-FICs.

Evaluation of Reporting Quality in Randomised Controlled Trials of Acupuncture for Acute Herpes Zoster by the CONSORT Statement and STRICTA Guidelines.

OBJECTIVE: To explore the methods for improving the reporting quality of randomised controlled trials (RCTs) on acupuncture through evaluating the reporting quality in RCTs of acupuncture for acute herpes zoster by the CONSORT statement and STRICTA guidelines. METHODS: English and Chinese databases were searched from database creation until October 2018 and updated to July 2019. The basic characteristics and methodological quality of the literatures included were evaluated based on the CONSORT statement and the STRICTA guidelines. Descriptive statistical analysis was used in this study. The agreement between the two researchers of all items was calculated by Cohen's kappa statistics. RESULTS: A total of 40 RCTs were included. Based on the CONSORT statement, items "Background," "Randomised" in the title or abstract," "Statistical methods," and "Outcomes and estimation" were good reporting, with positive rates >80%. However, the quality of reporting in items "Sample size," "Allocation concealment," "Implementation," "Blinding," "Flow chart," "Intent-to-treat analysis," "Ancillary analyses," and "Clinical Trials Register" was very poor, with positive rates <10%. Based on the STRICTA guidelines, good reporting existed in items "Acupuncture rational," "Points used," "Needle stimulation," "Needle retention time," "Course of treatment," "Control intervention," and "Treatment frequency," with positive ratings >80%. The reporting quality of items "Numbers of needles inserted," "Depth of insertion," "Responses elicited," and "Practitioner background" was lower, with positive rates <50%. The agreement of most items was judged as moderate, substantial, or good. CONCLUSION: The reporting quality of RCTs in acupuncture for acute HZ is generally inadequate. It is necessary that researchers and journal editors learn and raise the adoption of the CONSORT statement and STRICTA guidelines to enhance the reporting quality of the RCTs in acupuncture.

Additive manufacturing of specific ankle-foot orthoses for persons after stroke: A preliminary study based on gait analysis data.

The aim of present study is to investigate the feasibility of patient-specific ankle-foot orthoses fabricated using additive manufacturing (AM) techniques. Then, clinical performance of the AFOs manufactured using material PA12 was evaluated in stroke survivors based on gait analysis data. The ankle and foot were scanned by EinScan-Pro 3D scanner. The software Geomagic Studio was used for modifying the AFO model. After processing the original AFO model into the final required model, material PA12 were used to fabricate the AFOs by Multi Jet Fusion (MJF) technique. Finally, gait analysis of 12 stroke patients was conducted to compare the effects with and without AFO. It took 2 hours from processing the initial AFO model to the completion of final model, and the printing time was 8 hours. The printing thickness of the AFO was 1.2 mm. With respect to the temporal-spatial parameters, the velocity and stride length in the gait with AFO increased significantly as compared to the gait without AFO (P=0.001, P=0.002). The cadence increased, double limb support phase decreased, and the step length difference decreased in the gait with AFO; however, the difference was not statistically significant (P=0.117, P=0.075, P=0.051).This study confirmed the feasibility of patient-specific AFO fabricated by AM techniques, and demonstrated the process of modifying AFO models successfully. The specific ankle-foot orthoses fabricated by material PA12 have a significant effect on the improvement of velocity and stride length in people with stroke.

Preparation of LuAG Powders with Single Phase and Good Dispersion for Transparent Ceramics Using Co-Precipitation Method.

The synthesis of pure and well dispersed lutetium aluminum garnet (LuAG) powder is crucial and important for the preparation of LuAG transparent ceramics. In this paper, high purity and well dispersed LuAG powders have been synthesized via co-precipitation method with lutetium nitrate and aluminum nitrate as raw materials. Ammonium hydrogen carbonate (AHC) was used as the precipitant. The influence of aging time, pH value, and dripping speed on the prepared LuAG powders were investigated. It showed that long aging duration (>15 h) with high terminal pH value (>7.80) resulted in segregation of rhombus Lu precipitate and Al precipitate. By decreasing the initial pH value or accelerating the dripping speed, rhombus Lu precipitate was eliminated and pure LuAG nano powders were synthesized. High quality LuAG transparent ceramics with transmission >75% at 1064 nm were fabricated using these well dispersed nano LuAG powders.

[Acupoint sticking therapy for treatment of bronchial asthma: a multicenter controlled randomized clinical trial].

OBJECTIVE: To observe the effect of acupoint sticking on clinical symptoms and life quality in patients with bronchial asthma. METHODS: Multicenter randomized double-blind clinical trial was done, one hundred and eighty-eight cases were divided into a medication acupoint sticking group (125 cases) and a placebo group (63 cases). Dazhui (GV 14), Feishu (BL 13), Tiantu (CV 22), etc. were selected in both groups. The medication cakes were made of grinding pepper, brassica alba seeds, asarum, etc. into fine powder mixed with ginger oil and ginger juice, applied on acupoints in the acupoint sticking group. While another compound cakes made of powder of red rice, black rice, maize mixed with small amount of ginger juice, were used in the placebo group. Asthma Quality of Life Questionnaire(AQLQ), symptom scores during the day and night, scores of self effect, and the value of lung function were observed. RESULTS: The value of daily behavior and environmental factors of AQLQ, total scores of AQLQ, daytime symptoms and scores of self effect in the medication acupoint sticking group, were significantly improved compared to those of placebo group (all P<0.05). The lung function of forced expiratory volume in one second (FEV1) and the percentage of forced expiratory volume in one second in predicted value (FEV1/FVC) had no significant diffrence between two groups (both P>0.05). CONCLUSION: The acupoint sticking therapy can significantly improve clinical symptoms of patients with bronchial asthma, and can improve life quality of the patients.
