Objective To evaluate the therapeutic efficacy and safety of micro-invasive craniopuncture scavenging technique (MPST) for treatment of intracranial hematoma in patients with hypertensive cerebral hemorrhage (HICH).Methods All the clinical randomized controlled trial (RCT) studies published on MPST and internal medicine conservative treatment of HICH were searched via computer screening of databases including Cochrane clinical trials database, the Chinese biomedical literature database (CBM), Chinese periodical network full-text special topic database, Chinese science and technology periodical database and electronic periodicals database of Wanfang from January 2006 to January 2017. The study group was given the MPST plus basic treatment, and the control group was given conservative treatment. The studies collected meeting the eligible criteria were sorted and analyzed by the software RevMan 5.0, the differences in therapeutic effect and mortality were compared between the two groups, and a funnel chart was plotted to analyze the potential publication bias.Results A total of 13 RCTs published studies consistent with the eligible criteria were found, including1556 patients. The Meta-analysis showed that the effective rate in the study group was significantly higher than that in the control group [odds ratio (OR) = 4.29, 95% confidence interval (95%CI) 3.33 - 5.53,P < 0.01]; the fatality rate was markedly lower than that of the control group (OR = 0.25, 95%CI 0.19 - 0.35,P < 0.01). The funnel graph showed that each study had asymmetrical scatter plot of the variable quantity of research results, indicating a publication bias being present, which might be related to the subjectivity of the researchers in publishing their results.Conclusions Using MPST to treat HICH can significantly improve the therapeutic efficiency and reduce deterioration rate. However, due to the low quality of clinical research, it is necessary to carry out rigorous andmulti-center randomized controlled studies to further confirm the results.

Ischemic stroke is a common cerebrovascular disease, characterized by hypoxia and nutritional deficiency in local brain tissue due to insufficient blood supply. Angiogenesis, the formation of new vascular networks on the basis of existing blood vessels, is of great significance for increasing blood flow in the ischemic area of brain tissue, restoring blood and oxygen supply, and improving disease prognosis. This complex process is regulated by various factors, including cytokines, growth factors, and signaling pathways. Among these, the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway is considered a key regulatory pathway. It not only plays an important role in anti-apoptosis and promoting cell survival, but also regulates cell growth, differentiation, migration, and survival, while deeply participating in the regulation of angiogenesis. Chinese medicine offers unique advantages with its multi-component, multi-target, and multi-pathway approach in the treatment of stroke, showing significant potential in treating ischemic stroke. In recent years, it has been found that Chinese medicine can promote angiogenesis after ischemic stroke through the PI3K/Akt signaling pathway. This paper focuses on the PI3K/Akt signaling pathway as the research entry point, and explores in-depth the mechanisms by which Chinese medicine monomers, active components, extracts, derivatives, drug pairs, and Chinese medicine compounds promote angiogenesis after ischemic stroke. The research discusses the regulation of microRNAs (miRNA), endothelial progenitor cells (EPCs), apoptosis, upstream pro-angiogenic factors, and downstream target molecules. The paper also elaborates on related research progress, aiming to reveal how Chinese medicine can exert its potential utility in ischemic stroke treatment through this key signaling pathway, providing a theoretical basis for clinical treatment.

Objective:To compare the effect of local vibration and extracorporeal shock wave therapy (ESWT) on triceps spasticity and the walking ability of hemiplegic stroke survivors.Methods:Sixty-nine stroke survivors with hemiplegia were randomly divided into a control group, a vibration group and an ESWT group. The control group received 60 minutes of conventional Bobath rehabilitation treatment and motor relearning from Monday to Saturday for 4 weeks. For the vibration and ESWT groups, 10 minutes of that traditional therapy were replaced by either local vibration or extracorporeal shock wave treatment every Tuesday, Wednesday and Saturday. Before and after the treatment, the three groups were evaluated using the Comprehensive Spasticity Scale (CSS) and in terms of passive joint range of motion (PROM), ankle plantar flexion angle, 10m maximum walking speed, stride frequency, and stride length.Results:After the intervention the average CSS, PROM, and ankle plantar flexion angle were significantly better for all three groups than before the treatment. At that point the ESWT group′s averages were significantly better than those of the vibration group, and the vibration group′s averages were significantly superior to those of the control group. Walking speed, stride frequency and stride length had also improved significantly in all three groups, with those in the vibration and ESWT groups significantly outperforming the control group. There was no significant difference between the vibration and ESWT groups in terms of walking ability.Conclusions:Both local vibration and extracorporeal shock wave therapy improve triceps spasticity and the walking ability of hemiplegic stroke survivors. Shock waves are more effective for improving spasticity, but there is no significant difference between the therapies in terms of improving walking ability.

ObjectiveTo observe the effects of Jianpi Bushen Huoxue prescription (JPBSHX) on rat brain microvascular endothelial cells (RBMECs) based on hypoxia-inducible factor-1α (HIF-1α)/vascular endothelial growth factor (VEGF) signaling pathway, aiming to provide a theoretical basis for the treatment of ischemic stroke. MethodTwelve 8-week-old male SPF-grade SD rats were selected. Eight of them were randomly chosen and given 3.25 g·mL-1 JPBSHX solution by gavage at a dose of 10 mL·kg-1 for 5 consecutive days to prepare the medicated serum, which was then preserved for later use. The remaining four rats were given the same volume of normal saline. Follow-up operations were the same as those of the above eight rats. Normal rat serum was collected and stored for later use. RBMECs were revived, cultured, passaged, and randomly divided into five groups: normal group (20% normal rat serum+80% high glucose DMEM), model group (hypoxia-reoxygenation injury) (20% normal rat serum+80% glucose-free DMEM), medicated serum group (20% JPBSHX-medicated serum+80% glucose-free DMEM), medicated serum+HIF-1α inhibitor group (20% JPBSHX-medicated serum+HIF-1α inhibitor 1 mg +80% glucose-free DMEM), and medicated serum+VEGF inhibitor group (20% JPBSHX-medicated serum +VEGF inhibitor 1 mg+80% glucose-free DMEM). The relative protein expression levels of Claudin-1 and Claudin-5 in RBMECs, the expression levels of HIF-1α and VEGF in RBMEC culture supernatants, the repair ability of RBMECs, and the number of nodes, microvessels, and their lengths after 72 h of culture were observed in each group. ResultAfter 24 h of reoxygenation, the scratch healing rate in the model group was significantly lower than in the normal group (P<0.01). Compared with the result in the model group, the scratch healing rates significantly improved in the medicated serum group, medicated serum+HIF-1α inhibitor group, and medicated serum+VEGF inhibitor group (P<0.05). However, the healing rates in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group were significantly lower than that in the medicated serum group (P<0.05). The number of nodes, microvessels, and total length of microvessels in the model group were significantly lower than those in the normal group (P<0.01). These indicators significantly improved in the medicated serum group, medicated serum+HIF-1α inhibitor group, and medicated serum+VEGF inhibitor group compared with those in the model group (P<0.05), but were significantly lower in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group compared with those in medicated serum group (P<0.05). The relative expression levels of Claudin-1 and Claudin-5 proteins were significantly lower in the model group than in the normal group (P<0.01). These levels were significantly higher in medicated serum group, medicated serum+HIF-1α inhibitor group, and medicated serum+VEGF inhibitor group than those in the model group (P<0.05), but were significantly lower in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group than those in the medicated serum group (P<0.05). The expression levels of HIF-1α and VEGF in the RBMEC culture supernatants were significantly lower in the model group than those in the normal group (P<0.01). These levels were significantly higher in the medicated serum group, medicated serum+HIF-1α inhibitor group, and medicated serum+VEGF inhibitor group than those in the model group (P<0.05), but were significantly lower in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group than those in the medicated serum group (P<0.05). ConclusionJPBSHX can promote the proliferation, migration, and angiogenesis, such as tubule formation, of RBMECs damaged by hypoxia-reoxygenation injury, and this effect may be achieved through the regulation of the HIF-1α/VEGF signaling pathway.

The spread of COVID-19 has greatly threatened human health and economic growth. Angiotensin-converting enzyme 2 (ACE2) is a receptor for severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). By attaching to ACE2, SARS-COV-2 reduces its expression and induces lung injury. Vitamin D can inhibit the progression of COVID-19 by inhibiting the activity of ROCK pathway, up-regulating ACE2 expression and bio-availability, and slowing down the adverse reactions caused by Ang II accumulation. This study explored a novel mechanism, i.e., vitamin D protects against COVID-19-induced injury by upregulating ACE2 expression. It provides theoretical guidance for the role of Vitamin D in the prevention and treatment of COVID-19.

The core of diagnosing and treating diseases in traditional Chinese medicine lies in syndrome differentiation. The eight principles of syndrome differentiation serve as guidance for syndrome differentiation. As one of the eight principles of syndrome differentiation, the differentiation of deficiency and excess is the basic and critical method. Ischemic stroke is currently the leading cause harming the health of Chinese residents. Although the hypotheses about the cause of ischemic stroke have evolved from external wind to the later internal wind and to the modern theory of toxin damaging the brain collaterals, they all believe that this disease is rooted in internal deficiency and external excess. According to available studies, although stroke is characterized by complex pathogenesis and rapid progression of syndromes, the key cause evolution has a regularity, that is, from excess to deficiency. This article analyzes the historical evolution of the etiology, pathogenesis, and syndrome differentiation schemes of stroke. There are diverse schemes for the syndrome differentiation of stroke, which make it difficult to choose in clinical practice. In view of this problem, this paper puts forward a new approach of staging sequential treatment of ischemic stroke based on the differentiation of deficiency and excess according to the evolution law of the key cause of stroke. Furthermore, we conducted a randomized controlled study on 100 patients with ischemic stroke to evaluate this new approach. The results showed that the staging sequential treatment of ischemic stroke based on the differentiation of deficiency and excess demonstrated definite clinical efficacy. In addition, this article reviews the previous research results of our team and the research achievements of other teams to preliminarily explore the relationship between stroke syndromes and biomarkers, aiming to provide an objective basis for unveiling the pathogenesis of stroke. In summary, according to the key cause evolution (from excess to deficiency), the treatment of ischemic stroke by stages based on differentiation of deficiency and excess can facilitate the rapid intervention and improve the clinical efficacy on ischemic stroke.
