The therapeutic efficacy of guided therapy for PCI after acute myocardial infarction: A meta-analysis.

OBJECTIVE: To systematically evaluate the effects of lead therapies on percutaneous coronary intervention (PCI) after acute myocardial infarction (AMI). METHODS: A randomized controlled trial (RCT) in the CNKI, Wanfang, VIP, ProQuest, PubMed, Cochrane Library, Scopus, and Web of Science databases was searched until January 2023. Two researchers strictly screened and checked the included literature, extracted relevant data, and used the Cochrane Manual to assess the risk quality of the literature. Using RevMan 5.3 software, Meta-analysis of 4 main outcome measures [cardiac function-related indicators, 6-minute walking distance (6 MWT), quality of life (SF-36), Seattle angina pectoris scale (SAQ)], and 3 secondary outcome measures [adverse event incidence, death incidence, and readmission rate]. RESULTS: 22 studies were finally included with 1754 subjects, but the overall quality of the included studies was not high. The results of the meta-analysis showed that, in the cardiac function-related indicators compared to controls, improved left ventricular ejection fraction (LVEF) index (MD = 1.42, 95%CI [-0.94, 3.79], P < .00001); however, compared with the Baduanjin group, Tai Chi ball + Baduanjin group and control group, there was no significant difference (P > .05); compared with the control group, the guidance therapy group improved the left ventricular end-diastolic volume (LVEDV) index (MD = -4.67, 95%CI [-6.8, -2.71], P < .00001). In comparison, the lead group improved the 6 MWT (MD = 69.44, 95%CI [30.12, 108.76], P < .00001); the SF-36 score (MD = 10.05, 95%CI [8.68, 11.42], P < .00001])and the SAQ score (MD = 6.2, 95%CI [3.97, 8.44], P < .00001). Among the secondary outcome measures, the incidence of adverse events was statistically significant (RR = 0.17, 95%CI [0.1, 0.32], P < .00001); statistically significant (RR = 0.29, 95%CI (0.1, 0.87), P < .00001); readmission (RR = 0.39, 95%CI [0.17, 0.87, 0.89], P < .00001). CONCLUSION: Based on the current study, combining conventional therapy/ exercise or using simple lead therapy after PCI can improve the treatment effect and improve the quality of life.

The progress of molecules and strategies for the treatment of HBV infection.

Hepatitis B virus infections have always been associated with high levels of mortality. In 2019, hepatitis B virus (HBV)-related diseases resulted in approximately 555,000 deaths globally. In view of its high lethality, the treatment of HBV infections has always presented a huge challenge. The World Health Organization (WHO) came up with ambitious targets for the elimination of hepatitis B as a major public health threat by 2030. To accomplish this goal, one of the WHO's strategies is to develop curative treatments for HBV infections. Current treatments in a clinical setting included 1 year of pegylated interferon alpha (PEG-IFNα) and long-term nucleoside analogues (NAs). Although both treatments have demonstrated outstanding antiviral effects, it has been difficult to develop a cure for HBV. The reason for this is that covalently closed circular DNA (cccDNA), integrated HBV DNA, the high viral burden, and the impaired host immune responses all hinder the development of a cure for HBV. To overcome these problems, there are clinical trials on a number of antiviral molecules being carried out, all -showing promising results so far. In this review, we summarize the functions and mechanisms of action of various synthetic molecules, natural products, traditional Chinese herbal medicines, as clustered regularly interspaced short palindromic repeats and their associated proteins (CRISPR/Cas)-based systems, zinc finger nucleases (ZFNs), and transcription activator-like effector nucleases (TALENs), all of which could destroy the stability of the HBV life cycle. In addition, we discuss the functions of immune modulators, which can enhance or activate the host immune system, as well some representative natural products with anti-HBV effects.

Cytomembrane visualization using Stokes parameter confocal microscopy.

A new, to the best of our knowledge, method for Stokes vector imaging is proposed to achieve imaging and dynamic monitoring of a non-labeled cytomembrane. In this work, a polarization state vector is described by a Stokes vector and expressed in chrominance space. A physical quantity called polarization chromaticity value (PCV) corresponding to a Stokes vector is used as the imaging parameter to perform Stokes vector imaging. By using the PCV imaging technique, the Stokes vector can be expressed in three-dimensional real space rather than in a Poincare sphere. Furthermore, a four-way Stokes parameter confocal microscopy system is designed to measure four Stokes parameters simultaneously and obtain micro-imaging. Label-free living onion cell membranes and their plasmolysis process are selected as the representative micro-anisotropy experimental analysis. It is proved that PCV imaging can perform visualization of cytomembranes, and further, microscopic orientation is demonstrated. The prospect of universal measurement of anisotropy details for analysis and diagnosis is provided.

[Clinical observation on acupuncture for treatment of abdominal postoperative pain].

OBJECTIVE: To compare the therapeutic effects between acupuncture based on syndrome differentiation and analgesic on abdominal postoperative pain. METHODS: One hundred cases of abdominal postoperative pain were randomly divided into two groups, 50 cases in each one. In acupuncture group, the treatment was applied according to meridian differentiation and point selection on the affected meridian. Ashi points near to the incision as the main points and those closely connected with Zangfu functions were selected, such as Yanglingquan (GB 34), Taichong (LR 3) and Zusanli (ST 36), etc. In medication group, muscular injection of Bucinnazine was administered. The severity of pain was evaluated with Visual Analogue Scale (VAS) before and after treatment. RESULTS: The remarkably effective rate in acupuncture group was 60.0% (30/50), which was markedly better than that 28.0% (14/50) in medication group (P < 0.01). VAS scores in 30 min and 4 h after treatment as well as 24 h after operation in two groups were all reduced remarkably as compared with those before treatment (all P < 0.01), indicating the satisfactory analgesia in treatment. VAS scores in acupuncture group were lower apparently than those in medication group in 30 min and 4 h after treatment (P < 0.01,P < 0.05). CONCLUSION: Acupuncture has quick analgesia in treatment of abdominal postoperative pain, which is superior to muscular injection of Bucinnazine because of its advantages of long-term and significant efficacy.
