Effects of combined traditional Chinese medicine therapy in patients of lower limbs injuries with osteoporosis: A retrospective paired cohort study.

Studies have confirmed that the health hazards of patients with lower limb injuries combined with osteoporosis are more obvious. This study is mainly based on the Taiwan National Health Insurance Database, and through big data analysis, it shows that the combined treatment of traditional Chinese medicine (TCM) is helpful to the health of patients with lower limb injuries combined with osteoporosis. A total of 9989 combined TCM-treated patients and 19,978 2:1 sex-, age-, and index-year-matched controls who did not receive TCM treatment were selected from the Taiwan National Health Insurance Database. Cox proportional hazards analyzes were performed to compare fracture surgery, inpatient, and all-cause mortality during a mean follow-up period of 17 years. A total of 5406/8601/2564 enrolled-subjects (14.11%/25.46%/5.53%) had fracture surgery/inpatient/all-cause mortality, including 1409/2543/552 in the combined TCM group (14.11%/25.46%/5.53%) and 3997/6058/2012 in the control group (20.01%/30.32%/10.07%). Cox proportional hazard regression analysis showed a lower rate of fracture surgery, inpatient and all-cause mortality for subjects in the combined TCM group (adjusted hazard ratios [HR] = 0.723; 95% confidence intervals [CI] = 0.604-0.810, P < .001; adjusted hazard ratios [HR] = 0.803; 95% CI = 0.712-0.950, P = .001; adjusted HR = 0.842; 95% CI = 0.731-0.953, P = .007, respectively). After 10 years of follow-up, the cumulative incidence of fracture surgery in patients combining TCM treatment seems to be half of that without combining TCM treatment those are shown in Kaplan-Meier analysis with statistically significant (log rank, P < .001, P < .001, and P = .010, respectively). This study hopes to provide clinicians with the option of combined TCM treatment for patients of lower limbs injuries combined with osteoporosis, so that such patients will be associate with a lower risk of fracture surgery, inpatient or all-cause mortality.

Effects of Tai Chi Exercise on Balance Function in Stroke Patients: An Overview of Systematic Review.

Background: Tai chi (TC) has received increased attention in stroke rehabilitation, yet services are greatly underutilized. An increasing number of systematic reviews and meta-analyses (SRs/MAs) have begun to investigate the effects of TC on balance function in stroke patients. The aim of this current study was to systematically collate, appraise, and synthesize the results of these SRs/MAs using a systematic overview. Methods: Eight databases were searched: PubMed, Cochrane Library, Embase, Web of Science, CNKI, SinoMed, Chongqing VIP, and Wanfang Data. SRs/MAs of TC on balance function in stroke patients were included. Literature selection, data extraction, and assessment of the review quality were performed by two independent reviewers. Methodological quality was assessed by the Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2), reporting quality by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), and evidence quality by Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). Results: Nine SRs/MAs were included in this study. For methodological quality, what resulted in unsatisfactory methodological quality was noncompliance with critical item 4 (using a comprehensive literature search strategy) and critical item 7 (providing the list of excluded research literature). For reporting quality, what resulted in unsatisfactory reporting quality was inadequate reporting of Q1 (protocol and registration), Q8 (search), Q15 (risk of bias across studies), Q16 (additional analyses), Q22 (risk of bias across studies), Q23 (additional analysis), and Q27 (funding). For GRADE, the evidence quality was high in 0, moderate in 3, low in 11, and very low in 6. Risk of bias was the most common factor leading to downgrading of evidence, followed by inconsistency, imprecision, publication bias, and indirectness. Conclusions: TC may have beneficial effects on balance function in stroke survivors; however, this finding is limited by the generally low methodology, reporting quality, and evidence quality for published SRs/MAs.

The Role of Traditional Chinese Medicine Nursing for Stroke: An Umbrella Review.

BACKGROUND: An increasing number of systematic reviews/meta-analyses (SRs/MAs) of clinical trials have begun to investigate the effects of traditional Chinese medicine (TCM) nursing in patients with stroke. To systematically appraise and synthesize these results, we conducted an overview of SRs/MAs. METHODS: Eight databases from their inception to April 2020 were searched to include all SRs/MAs on TCM nursing for stroke. Methodological quality assessment was performed using Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2) and evidence quality assessment was performed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). RESULTS: Eleven SRs/MAs regarding TCM nursing for stroke were included. The assessments with AMSTAR-2 indicated that the methodological quality of all included SRs/MAs was critically low. According to the evaluation results of GRADE, 10 (40%) outcomes were rated as critically low-quality evidence, 7 (28%) low-quality evidence, and 8 (32%) moderate-quality evidence. Descriptive analysis results showed that TCM nursing was effective for stroke. CONCLUSIONS: All included SRs/MAs suggested positive findings of TCM nursing for stroke, but the credibility of the results is limited. Studies with methodologically rigorous and adequately powered are still needed in this field.

Tubeimoside I-induced lung cancer cell death and the underlying crosstalk between lysosomes and mitochondria.

Cancer cells have developed chemoresistance and have improved their survival through the upregulation of autophagic mechanisms that protect mitochondrial function. Here, we report that the traditional Chinese anticancer agent tubeimoside I (Tub), which is a potent inhibitor of autophagy, can promote mitochondria-associated apoptosis in lung cancer cells. We found that Tub disrupted both mitochondrial and lysosomal pathways. One of its mechanisms was the induction of DRP1-mediated mitochondrial fragmentation. Another mechanism was the blocking of late-stage autophagic flux via impairment of lysosomal acidification through V-ATPase inhibition; this blocks the removal of dysfunctional mitochondria and results in reactive oxygen species (ROS) accumulation. Excessive ROS accumulation causes damage to lysosomal membranes and increases lysosomal membrane permeability, which leads to the leakage of cathepsin B. Finally, cathepsin B upregulates Bax-mediated mitochondrial outer membrane permeability and, subsequently, cytosolic cytochrome C-mediated caspase-dependent apoptosis. Thus, the cancer cell killing effect of Tub is enhanced through the formation of a positive feedback loop. The killing effect of Tub on lung cancer cells was verified in xenografted mice. In summary, Tub exerts a dual anticancer effect that involves the disruption of mitochondrial and lysosomal pathways and their interaction and, thereby, has a specific and enhanced killing effect on lung cancer cells.

[Study on the needling depth of lumbar Jiaji (Ex-B2) points with CT imaging location].

OBJECTIVE: To study on safe depth and angle of needling lumbar Jiaji (Ex-B2) for treatment of prolapse of lumbar intervertebral disc. METHODS: CT technique was used for scanning investigation on the depth and angle of needling lumbar Jiaji (Ex-B2). RESULTS: When the acupuncture needle or puncture needle was inserted at an angle of 20-30 degrees to the sagittal plane of the human body, the tip of needle could reached to extradural posterior space of the depth of lumbar Jiaji points (being the best inserting depth), in which catgut or medicine could be placed. CONCLUSION: Acupuncture or catgut stimulating the extradural posterior space at the depth of lumbar Jiaji is superior to the traditional needling method in treatment of prolapse of lumbar intervertebral disc.
