Benign prostatic hyperplasia(BPH) is a common disease in middle-aged and elderly men, with lower urinary tract symptoms as the main manifestation, severely affecting the quality of life of patients. The pathogenesis of BPH is not yet fully understood, and there are still some challenges and limitations in western medicine treatment for BPH. Therefore, finding new and more effective treatment strategies is urgent. In recent years, many basic and clinical studies have confirmed the important role of traditional Chinese medicine in the treatment of BPH. This article reviews the progress of basic and clinical research in the treatment of BPH with traditional Chinese medicine, and believes that basic research mainly focuses on the active ingredients of Chinese medicine [regulating pathways such as NF-E2-related factor 2(Nrf2)/antioxidant response element(ARE), nuclear factor κB(NF-κB), epidermal growth factor receptor(EGFR)/signal transducer and activator of transcription 3(STAT3), phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR), p38 mitogen-activated protein kinase(p38 MAPK)/forkhead box O subtype(FOXO3a), etc.], single Chinese herbs(regulating inflammatory factors, oxidative stress-related proteins, cell cycle-related proteins, and apoptotic factors, etc.), and Chinese herbal compounds and patent medicines [regulating extracellular signal-regulated kinase(ERK1/2), transforming growth factor-β(TGF-β)/Smad, mitogen-activated protein kinase(MAPK), PI3K/Akt, Nrf2, trefoil factor 2(TFF2)/Wnt, interleukin-6(IL-6)/Janus kinase 2(JAK2)/STAT3, hypoxia-inducible factor 1α(HIF-1α)/vascular endothelial growth factor receptor(VEGFR), etc.], and then play a therapeutic role by inhibiting BPH cell proliferation, oxidative stress, inflammatory response, promoting apoptosis, and inhibiting epithelial-mesenchymal transition. Clinical studies mainly focus on internal treatment, external treatment, combined internal and external treatment, and integrated Chinese and western medicine treatment as the main methods, aiming to improve traditional Chinese medicine syndrome scores, prostate symptom scores, residual urine volume, effective bladder volume, sexual quality of life, increase average urine flow rate, maximum urine flow rate, and promote balance of sex hormone secretion. Through this research, it is hoped to provide some reference ideas for clinical research and drug development for BPH.

This article summarizes the clinical decision-making of patients requiring cardiovascular surgery after COVID-19 infection, and advises on the corresponding recommendations according to the existing evidence-based medical evidence as well as the actual clinical practice experience of relevant experts. The main content of the article includes special requirements for cardiovascular surgical treatment indications in patients with COVID-19 infection, selection of surgical timing, special requirements of preoperative, intraoperative and postoperative management, etc., which aims to provide COVID-19-infected patients with guidance on rational decision-making when receiving cardiovascular surgery.

Objective:To observe the effect of Yi Jin Jing(Sinew-transforming Qigong Exercises)intervention on anxiety in asymptomatic patients with Corona Virus Disease 2019(COVID-19)infection during quarantine.Methods:A total of 160 asymptomatic patients with COVID-19 infection were stratified by gender and divided into an observation group and a control group by the stratified randomization method,with 80 cases in each group.The control group was given basic nursing in the cabin,and the observation group was given additional Yi Jin Jing exercises once a day,20 min each time,and trained continuously until 1 d before leaving the cabin.The Hamilton anxiety scale(HAMA)score was compared between the two groups.Results:A total of 154 cases were included for data analysis in this study,including 74 cases in the observation group and 80 cases in the control group.After intervention,the HAMA scores in both groups increased(P<0.05),while the score in the observation group was lower than that in the control group(P<0.05).In the control group,the HAMA score of females after intervention was higher than that of males.The scores of mental anxiety and somatic anxiety in both groups were higher than those before intervention,while the score of mental anxiety in the observation group was significantly lower than that in the control(P<0.05).However,there was no statistical difference in the somatic score between the two groups(P>0.05).Conclusion:Patients with COVID-19 infection will get anxious during quarantine.Yi Jin Jing exercise can effectively reduce the aggravation of anxiety in asymptomatic patients with COVID-19 infection during concentrated quarantine.

Objective: To quantitatively evaluate the association between mild cognitive impairment and all-cause mortality. Methods: The research papers of the association between cognitive impairment and all-cause mortality in the elderly in the databases of PubMed, EMBASE, Wang Fang data and CNKI published as of August 1, 2021 were comprehensively retrieved. Software R 4.02 was used for Meta-analysis. Results: A total of 9 research papers were included, involving 48 709 patients. The quality of included papers was high. The results of Meta-analysis showed that the association between mild cognitive impairment and the increased risk of all-cause mortality was statistically significant. Compared with the normal cognitive population, the risk of mortality in the elderly with mild cognitive impairment increased by 39% (HR=1.39, 95%CI: 1.18-1.63). Conclusions: The current research evidence showed that mild cognitive impairment assessed by MMSE screening scale can be used as an independent predictor of the increased risk of all-cause mortality in the elderly population in China. However, due to the limitation of the number of included studies and sample size, the conclusions need to be supported by more evidence studies.

In the pharmacopoeia, many process parameters for the purification process of Scutellariae Radix are unclear. In this study, deterministic screening design combined with design space method was used to optimize the purification process of Scutellariae Radix extract. Nine method parameters such as mass fraction of solution(X_1), first acid precipitation pH(X_2) and first holding time(X_3) in the purification process were firstly studied by definitive screening design. The yield of baicalin was defined as the evaluation index. A stepwise regression method was used then to build quantitative models between evaluation index and method parameters and the three most critical impact parameters were determined. Probability-based design space was calculated and successfully verified with the experimental error simulation method. Finally, the second standing temperature, the first standing temperature and the pH value of the second acid precipitation were determined as the three most critical method parameters. The recommended operating space was as follows: the second standing temperature 5-7 ℃, the first standing temperature 13-15 ℃, and the pH of the second acid precipitation 1.5-1.7. Within this operating space, the baicalin yield in the purification process was over 80%, and the probability of reaching the standard was over 0.96. In this study, we optimized the effect of various parameters for the purification process of the Scutellariae Radix extract in the pharmacopoeia on the yield of baicalin and provided a reference for industrial production of the exact of Scutellariae Radix.

Cerebral infarction is a clinical disease with corresponding neurological symptoms caused by cerebral ischemia and hypoxia caused by cerebral blood supply disorder. It is one of the most common cerebrovascular diseases and a serious threat to human health. The prevention and treatment of cerebral infarction has an important social significance. Angiogenesis is the key starting point for medical treatment of cerebral infarction, and signal transduction and transcriptional activators (STAT)/hypoxia inducing factor-1(HIF-1)/vascular endothelial growth factor (VEGF) pathway are important pathways to mediate angiogenesis after cerebral infarction. This paper took the angiogenesis as the starting point and the upstream molecules of STAT/HIF-1/VEGF signal pathway STAT3 and miRNA as the main study objects, and comprehensively discussed the results of chip sequencing, experimental research, traditional Chinese medicine (TCM) pathogenesis and TCM treatment. Based on the regulatory mode of "TF-miRNA" and the idea of "micro-whole", it is suggested that under the guidance of the basic theory of TCM, cubic compound prescriptions of TCM and its active components might activate the STAT/HIF-1/VEGF signal pathway through STAT3/miRNA feedback loop to promote angiogenesis after cerebral infarction, which puts forward a deep molecular mechanism and new direction for the treatment of cerebral infarction with TCM.

AIM:To investigate the effects of Jiawei-Naotai formula (JWNTF) on ATF4/CHOP/Puma pathway in hippocampal neurons of ovariectomized female rats with cerebral ischemia.METHODS:The female rats were randomly divided into sham group, model group, JWNTF group and positive control group.The rats, expect in the sham group, were ovariectomized.The rats in each group were intragastric administration 11 days after ovariectomy.The rats in sham group and model group were given a gavage of 0.9％Na Cl, while the rats in other groups were administrated by corresponding therapy intragastrically for 3 d.The regional cerebral ischemia model was established by middle cerebral artery occlusion (MCAO) suture method 14 days after ovariectomy.The behaviors of the rats were evaluated 24 h after cerebral ischemia.The mRNA levels of Bax, Bcl-2 and caspase-3 were detected by RT-qPCR, and the protein expression of Bax, Bcl-2, caspase-3, ATF4, CHOP and Puma was determined by Western blot.RESULTS:Compared with sham group, the neurobehavioral scores significantly increased in other groups (P<0.05).Compared with model group, the neurobehavioral scores were significantly decreased in positive control group and JWNTF group (P<0.05).The protein expression of Bax, caspase-3, ATF4, CHOP and Puma, and the mRNA expression of Bax and caspase-3 in the hippocampus were much higher, and Bcl-2 was lower in model group than those in sham group (P<0.05).JWNTF significantly reduced the protein expression of Bax, caspase-3, ATF4 and CHOP, and the mRNA expression of Puma, Bax and caspase-3, and markedly increased the expression of Bcl-2 at mRNA and protein levels compared with model group.CONCLUSION:The JWNTF protects against brain damage induced by cerebral ischemia, which may be related to inhibitiing the expression of ATF4/CHOP/Puma pathway-related molecules at mRNA and protein levels.
