Potential impacts of climate change on the distribution of the relict plant Shaniodendron subaequale.

Shaniodendron subeaqualis is a tertiary relict plant unique to China. This species has high greening, ecological, and scientific research value, and has been listed as a national I-level key protected plant. Clarifying the main climatic factors restricting the geographical distribution of S. subeaqualis and predicting the potential geographical distribution pattern of this species can provide a scientific basis for the protection of the germplasm resources of this rare species. Based on 104 S. subeaqualis natural distribution records and 9 climate factors, the MaxEnt software was used to predict the potential suitable areas of S. subeaqualis in different periods (LGM, MH, Current, SSP245-2050s, SSP245-2090s, SSP585-2050s, SSP585-2090s). The results showed that the contemporary AUC predicted by MaxEnt is 0.996, with high simulation accuracy; Precipitation in the driest season (Bio17), the average temperature in the coldest season (Bio11) are main factors affecting the distribution of S. subeaqualis. At present, the suitable area of S. subeaqualis is mainly distributed in Jiangsu, Anhui, and Zhejiang province, with a total area of 11.575 × 104 km2, of which the high suitable area is 1.424 × 104 km2 and the medium suitable area is 3.826 × 104 km2. In the LGM, the area of S. subeaqualis was roughly similar to that of the contemporary period, but there was a southward migration phenomenon in some areas, such as the suitable area in the south of Zhejiang. In order to avoid the influence of ice age, S. subeaqualis moved to nearby refuge places, such as Dabie Mountain area of Anhui province, the west of Tianmu Mountain area of Zhejiang province and mountain area of Jiangsu province. In the MH, the suitable area for S. subeaqualis was reduced and moved northward to a small extent. In the future period, the suitable range of S. subeaqualis will not change greatly, but the overall degree of fragmentation will intensify. If effective measures are not taken, it is bound to bring severe challenges to the survival of S. subeaqualis. In order to protect S. subeaqualis germplasm resources more effectively, it is suggested to dynamically monitor the existing S. subeaqualis population and take various measures actively to reduce the negative effects of climate change on S. subeaqualis.

The effects of Tai Chi on physical function and safety in patients with rheumatoid arthritis: A systematic review and meta-analysis.

Background: Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory autoimmune disease that results in the destruction of joints, connective tissues, muscle, tendons and fibrous tissue. Until now, there are no cure therapies. Objective: We aimed to assess the effectiveness of Tai Chi (TC) on RA patients by meta-analysis. Methods: The PubMed, Cochrane Library, EMBASE, web of science, China National Knowledge Infrastructure and Google Scholar were searched up to January 2023. We included randomized controlled trials (RCTs) or controlled clinical trials (CCTs) comparing TC to control conditions for RA patients. Review Manager (Version 5.3) software was used to analyze outcomes of time to walk 50 feet, joint tenderness, number of swollen joints or tender joints, handgrip strength, pain, the Health Assessment Questionnaire (HAQ) and withdraws overall. Results: A total of 351 patients with RA from six RCTs and three CCTs were included for meta-analysis. TC could also significantly decrease withdrawals overall in studies (OR = 0.28, 95% CI 0.12 to 0.67, p = 0.002). No significant treatment effects of physical function were identified of the other outcomes. Conclusion: Our findings indicated that TC was safe to RA patients, but it cannot improve physical function and pain. However, there is still lack of more evidence.

Does kinesio taping plus exercise improve pain and function in patients with knee osteoarthritis?: A systematic review and meta-analysis of randomized controlled trials.

Background: Kinesio taping (KT) and exercise are described for improving pain and function of knee osteoarthritis (KOA) patients in most studies. However, the question remains if KT plus exercise is better than only exercise treatment. Objective: To perform a systematic review and meta-analysis of randomized controlled trials (RCTs) to assess the effects of KT plus exercise in improving pain and knee function of KOA patients. Methods: The databases PubMed, Cochrane Library, EMBASE, Springer, web of science and China National Knowledge Internet (CNKI) were searched till July 2022. People diagnosed with KOA were included. The intervention was KT plus exercise, but the comparison group was intervened only with exercise. Outcome measures were the Visual Analogue Scale (VAS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and Timed Up and Go (TUG). Only RCTs were included. The Review Manager software (Version 5.3.5) was used to assess risk of bias, statistical heterogeneity and meta-analysis. Results: The inclusion criteria were satisfied by 642 individuals from sixteen RCTs. There was a significant difference between KT plus exercise group and only exercise group in terms of VAS score after intervention (mean difference (MD) = -0.86; 95% CI = -1.32 to -0.40; p = 0.0003). In terms of VAS at follow-up period (MD = -0.58; 95% CI = -1.41 to 0.25; p = 0.17), WOMAC score (MD = 0.28; 95% CI = -9.16 to 9.71; p = 0.95) and TUG after intervention (MD = -0.74; 95% CI = -1.72 to 0.24; p = 0.14), no significant difference was found. Conclusion: Although KT plus exercise reduced pain better than exercise, it did not enhance knee function in patients with KOA. These conclusions may change when more high-quality research is conducted.

Tai Chi on bone mineral density of postmenopausal osteoporosis: A protocol for systematic review and meta-analysis.

BACKGROUND: Osteoporosis is a clinically common metabolic disease, especially in postmenopausal women. Tai Chi might be beneficial in osteoporosis patients. This study will be performed to examine the effects of Tai Chi on bone mineral density of postmenopausal osteoporosis. METHODS: We will search the electronical databases and hand-searching journals or reference lists. The study screening and data extraction will be carried out by 2 investigators independently. The primary outcome is bone mineral density (lumbar spine, Ward's triangle, trochanter, proximal femur, femoral neck, or total hip). Secondary outcomes are pain score, alkaline phosphatase, osteocalcin, and adverse effects. Review Manager V.5.3 software will be used to compute the data. RESULTS: The results of the study will provide a reliable evidence to assess the effects of Tai Chi on bone mineral density of postmenopausal osteoporosis. CONCLUSION: The conclusion of our systematic review will answer whether Tai Chi is an effective intervention to improve bone mineral density of postmenopausal osteoporosis.

Shi's Yi-Qi Bu-Shen Tong-Luo decoction combined with manipulation in the management of wrist stiffness after distal radius fracture: Study protocol clinical trial (SPIRIT Compliant).

INTRODUCTION: Wrist stiffness is a common sequela of distal radial fractures. Manipulation is generally used and effective, but problems exist, such as intense pain, swelling during the process of manipulation and long treatment period. Therefore, a combinative therapeutic strategy is necessary to benefit rehabilitation after distal radius fracture. Shi's Yi-Qi Bu-Shen Tong-Luo decoction (BTD) combined with wrist manipulation has been used in the Shanghai Ninth People's Hospital Huangpu Branch in last few decades. BTD has potential therapeutic effects on rehabilitation after distal radius fracture, which should be evaluated by rigorous clinical trial. METHODS/DESIGN: A randomized, double-blind, placebo-controlled clinical trial will be conducted to determine the efficiency of BTD in relief of wrist stiffness and pain and function rehabilitation. A total of 80 wrist stiffness patients with or without pain and edema will be enrolled, and treated with wrist manipulation plus BTD or placebo for 4 weeks. The primary outcome measure is the Cooney wrist score. The second outcome measures include pain numerical rating scale, patient rated wrist evaluation, 36-item short form health survey questionnaire, and side effects. DISCUSSION: Although BTD has shown effects on rehabilitation after distal radius fracture in the Shanghai Ninth People's Hospital Huangpu Branch for decades, the universality of this efficacy needs evaluated. The results of this trial will provide a convincing evidence. TRIAL REGISTRATION: ChiCTR2000029260, January 19, 2020.

[Experimental study of electroacupuncture improving the obstruction of vestibular microcirculation in vertebrobasilar insufficiency and the effect on vestibulo-ocular reflex].

AIM: To investigate the mechanism of EA improving the obstruction of inner ear microcirculation and the effect on the vestibulo-ocular reflex (VOR) by comparing the effects of electroacupuncture (EA) with sibelium (flunarizine hydrochloride) on vertebrobasilar insufficiency(VBI). METHODS: Injected with sclerosant-775 injection into the solt tissue on the left side of cervical vertebral transverse processes of rabbits to set up the vertebral artery type of cervical spondylosis (VCS) models. Electronystagmography (ENG) induced by linear acceleration (LA) and horizontal rotation (HR), the transcranial Doppler (TCD), laser Doppler flowmetry (LDF) and hemorheology were used to measure changes of the frequencies of nystagmus, the hemodynamics in the basilar artery (BA), inner ear blood flow(IEBF) and blood viscosity in VBI rabbits. RESULTS: The frequencies of ENG, the velocity of blood flow in BA and IEBF decreased obviously, and whole blood middle where viscosity, whole blood lower where viscosity and erythrocyte distortion index ( EDI) increased significantly in the model group. Sibelium could reduce whole blood viscosity and EDI, and increased the systolic phase velocity (Vs) of blood flow in BA, but had no effect on diastolic phase velocity (Vd) and mean velocity (Vm). EA could not reduce the viscosity of blood and EDI, but had more significant effects on improving IEBF and ENG induced by LA than those of sibelium,and had the tendency of increasing Vs, Vd and Vm. EA and sibelium had no effect on improving ENG induced by HR. CONCLUSION: Inner ear microcirculation obstruction caused by VBI can induce dysfunctions of vestibule cyst macula and horizontal semicircular canals. EA may depend upon the neurohumoral regulation to improve VBI, and ameliorate inner ear blood supply obstruction by enhancing mechanism of local adjusting for microcirculation in the inner ear to recover vestibular cyst macula irritability for LA chiefly. There exist complicated mechanism that EA adjusts blood flow distribution and vestibular signal transduction in vestibular organ in VBI model likely, and remain to be researched deeply.
