Objective:To observe any effect of dynamic instability training on the balance and posture control of persons with chronic ankle instability (CAI).Methods:Thirty persons with CAI were divided at random into a control group and an observation group, each of 15. Both groups received routine rehabilitation interventions (including ankle strength training, kinesio taping, and vibration training), while the observation group additionally underwent 20 minutes of dynamic instability training daily, 5 days a week for 4 consecutive weeks. Before and after the treatment, everyone′s balance was evaluated using the Berg balance scale (BBS) and the star moving balance test (SEBT). Surface electromyography (sEMG) was used to collect electromyograms of the affected peroneus longus, tibialis anterior, rectus femoris and medialis femoris muscles of both groups within 100ms before and after landing in the jump-landing test. The intensity of muscle activation was thus analyzed.Results:After the treatment there was significant improvement in the average BBS scores, anterior medial SEBT, medial SEBT and posterior medial SEBT results of both groups. On average, all three SEBT results [(80.27±4.06)cm, (90.27±4.06)cm and (97.73±3.47)cm respectively] were significantly better in the observation group than in the control group. The standardized integrated electromyographs of the peroneus longus, tibialis anterior, rectus femoris and medialis femoris muscles on the affected sides showed significant improvement compared with before the treatment, but there too the observation group′s results were significantly better than those of the control group.Conclusions:Combining dynamic instability training with conventional rehabilitation can further improve the balance and postural control of persons with chronic ankle instability.

Receptor-interacting protein kinase 1 (RIPK1) plays an essential role in regulating the necroptosis and apoptosis in cerebral ischemia-reperfusion (I/R) injury. However, the regulation of RIPK1 kinase activity after cerebral I/R injury remains largely unknown. In this study, we found the downregulation of protein arginine methyltransferase 1 (PRMT1) was induced by cerebral I/R injury, which negatively correlated with the activation of RIPK1. Mechanistically, we proved that PRMT1 directly interacted with RIPK1 and catalyzed its asymmetric dimethylarginine, which then blocked RIPK1 homodimerization and suppressed its kinase activity. Moreover, pharmacological inhibition or genetic ablation of PRMT1 aggravated I/R injury by promoting RIPK1-mediated necroptosis and apoptosis, while PRMT1 overexpression protected against I/R injury by suppressing RIPK1 activation. Our findings revealed the molecular regulation of RIPK1 activation and demonstrated PRMT1 would be a potential therapeutic target for the treatment of ischemic stroke.

OBJECTIVE: To explore and quantify the association of hot night exposure during the sperm development period (0-90 lag days) with semen quality. METHODS: A total of 6,640 male sperm donors from 6 human sperm banks in China during 2014-2020 were recruited in this multicenter study. Two indices (i.e., hot night excess [HNE] and hot night duration [HND]) were used to estimate the heat intensity and duration during nighttime. Linear mixed models were used to examine the association between hot nights and semen quality parameters. RESULTS: The exposure-response relationship revealed that HNE and HND during 0-90 days before semen collection had a significantly inverse association with sperm motility. Specifically, a 1 °C increase in HNE was associated with decreased sperm progressive motility of 0.0090 (95% confidence interval [ CI]: -0.0147, -0.0033) and decreased total motility of 0.0094 (95% CI: -0.0160, -0.0029). HND was significantly associated with reduced sperm progressive motility and total motility of 0.0021 (95% CI: -0.0040, -0.0003) and 0.0023 (95% CI: -0.0043, -0.0002), respectively. Consistent results were observed at different temperature thresholds on hot nights. CONCLUSION Our findings highlight the need to mitigate nocturnal heat exposure during spermatogenesis to maintain optimal semen quality.

As an innovative dosage form, traditional Chinese medicine(TCM) dry powder inhalers have emerged as a focal point in the research and development of new preparations due to its high efficiency, safety, and bioavailability. This paper systematically reviewed the relevant literature and patents associated with TCM dry powder inhalers to analyze the origins and the current research and development status. Furthermore, this paper probed into the research and development ideas of TCM dry powder inhalers regarding clinical positioning, prescription screening, and druggability. Additionally, the paper thoroughly analyzed the technical barriers in druggability studies and elaborated on corresponding research techniques and coping measures. Furthermore, it emphasized the need for improved regulations and policies governing TCM dry powder inhalers, advocated for strengthened oversight, and called for the establishment of a scientific quality evaluation system. Measures such as promoting production-education-research collaboration, enhancing personnel training, and fostering international exchanges were proposed to provide a scientific and systematic reference for the future research, development, and application of TCM dry powder inhalers, thereby facilitating the rapid modernization of TCM.

The theory of yin and yang is the modest differentiation thought of the traditional Chinese medicine under the guidance of overall dialectics,and the dynamic changes of yin and yang profit and loss can reflect the life activities of the human body.In the early literature research and clinical practice,the author's team found that the"yang deficiency and yin stagnation"is the key pathogen of colorectal cancer,the yang qi is insufficient,and the metabolites of the yin such as phlegm,wetness and stasis are lost in gasification and accumulate to form a"yin tumor",which is stagnant in the intestine and forms colorectal cancer.Yang Qi is the process of normal cell metabolism to produce energy,Yang Qi is insufficient,the"yin knot"of the thing in the body polymerizes into tumors,The imbalance of yin and yang can cause changes in energy or substance metabolism in the body,and glutamine is one of the amino acid which is the largest consumption of tumor cells,and its metabolic process not only provides a material basis for tumor cell growth,but also creates an acidic microenvironment of hypoxia to promote the proliferation and growth of tumor cells.This paper discusses the characteristics of glutamine metabolism of colorectal cancer cells in detail,aiming to explain the occurrence of colorectal cancer from the pathogenesis of"yang deficiency yin knot",and to explain the scientific theory of traditional Chinese medicine in the treatment of coloral cancer with the principle of Wenyang Tongxia,aiming to provide new ideas and methods for the comprehensive treatment of CRC.

Objective To analyze the thyroid hormone levels in patients with acute ischemic stroke (AIS) and non-valvular atrial fibrillation (NVAF). Methods A total of 121 patients with AIS were selected, and were divided into NVAF group (AIS patients with NVAF) and control group (AIS patients without atrial fibrillation). Serum levels of triiodothyronine (T₃), free triiodothyronine (FT₃), thyroxine (T₄), free thyroxine (FT₄) and thyroid stimulating hormone (TSH) in two groups were measured and compared. The survival of the two groups was compared. Results The serum T₃ level in the NVAF group was significantly lower than that in the control group (P < 0.05). There were no significant differences in serum FT₃, T₄, FT₄ and TSH levels between the two groups (P>0.05). There was no significant difference in survival between the two groups (P>0.05). Conclusion NVAF is associated with serum T₃ levels in AIS patients. There is no correlation between the risk of death and NVAF in AIS patients.
