Effectiveness and Safety of Chinese Medicine at Shenque (CV 8) for Primary Dysmenorrhea: A Systematic Review and Meta-Analysis of Randomized Controlled Trials / 中国结合医学杂志

BACKGROUND@#Primary dysmenorrhea (PD) is the most common complaint associated with menstruation and affects up to three-quarters of women at some stage of their reproductive life. In Chinese medicine, navel therapy, treatment provided at Shenque (CV 8), is used as a treatment option for PD.@*OBJECTIVE@#To evaluate the effect of navel therapy on pain relief and quality of life in women with PD, compared with Western medicine (WM).@*METHODS@#China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), SinoMed and Wanfang Database, MEDLINE, the Cochrane Library, Embase, Web of Science, and the International Clinical Trial Registry of the U.S. National Institutes of Health were searched from their inceptions to April 1, 2021. Randomized controlled trials (RCTs) assessing therapeutic effects of navel therapy on PD were eligible for inclusion. RevMan 5.4 software was used for data analyses. The certainty of the evidence was assessed using the online GRADEpro tool.@*RESULTS@#Totally 24 RCTs involving 2,614 participants were identified. Interventions applied to acupuncture point CV 8 included: herbal patching, moxibustion or combined navel therapy (using at least 2 types of stimulation). Compared to placebo, there was a significant effect in favor of navel therapy on reducing overall menstrual symptom scores at the end of treatment [mean difference: -0.82, 95% confidence interval (CI): -1.00 to -0.64, n=90; 1 RCT]. As compared with Western medicine, navel therapy had a superior effect on pain intensity as assessed by Visual Analogue Scale at the end of treatment [standardized mean difference (SMD): -0.64, 95% CI: -1.22 to -0.06, I2=80%, n=262; 3 RCTs]; on symptom resolution rate at 3-month follow-up (risk ratio: 1.94, 95% CI: 1.47 to 2.56, n=1527, I2=38%; 13 RCTs); and on global menstrual symptoms score at the end of treatment (SMD: -0.67, 95% CI: -0.90 to -0.45, I2=63%, n=990; 12 RCTs). Subgroup analyses showed either a better or an equivalent effect comparing navel therapy with Western medicine. No major adverse events were reported. The methodological quality of included trials was poor overall.@*CONCLUSIONS@#Navel therapy appears to be more effective than Western medicine in decreasing menstrual pain and improving overall symptoms of PD. However, these findings need to be confirmed by well-designed clinical trials with adequate sample size (Systematic review registration at PROSPERO, No. CRD42021240350).

Antiplatelet and myocardial protective effect of Shexiang Tongxin Dropping Pill in patients undergoing percutaneous coronary intervention: A randomized controlled trial / 中西医结合学报

BACKGROUND@#High on-clopidogrel platelet reactivity could be partially explained by loss-of-function alleles of CYP2C19, the enzyme that converts clopidogrel into its active form. Shexiang Tongxin Dropping Pill (STDP) is a traditional Chinese medicine to treat angina pectoris. STDP has been shown to improve blood flow in patients with slow coronary flow and attenuate atherosclerosis in apolipoprotein E-deficient mice. However, whether STDP can affect platelet function remains unknown.@*OBJECTIVE@#The purpose of this study is to examine the potential effects of STDP on platelet function in patients undergoing percutaneous coronary intervention (PCI) for unstable angina. The interaction between the effects of STDP with polymorphisms of CYP2C19 was also investigated.@*DESIGN, PARTICIPANTS AND INTERVENTION@#This was a single-center, randomized controlled trial in patients undergoing elective PCI for unstable angina. Eligible subjects were randomized to receive STDP (210 mg per day) plus dual antiplatelet therapy (DAPT) with clopidogrel and aspirin or DAPT alone.@*MAIN OUTCOME MEASURES@#The primary outcome was platelet function, reflected by adenosine diphosphate (ADP)-induced platelet aggregation and platelet microparticles (PMPs). The secondary outcomes were major adverse cardiovascular events (MACEs) including recurrent ischemia or myocardial infarction, repeat PCI and cardiac death; blood biomarkers for myocardial injury including creatine kinase-MB isoenzyme (CK-MB) and high-sensitive troponin I (hsTnI); and biomarkers for inflammation including intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), monocyte chemoattractant protein-1 (MCP-1) and galectin-3.@*RESULTS@#A total of 118 subjects (mean age: [66.8 ± 8.9] years; male: 59.8%) were included into analysis: 58 in the control group and 60 in the STDP group. CYP2C19 genotype distribution was comparable between the 2 groups. In comparison to the control group, the STDP group had significantly lower CK-MB (P < 0.05) but similar hsTnI (P > 0.05) at 24 h after PCI, lower ICAM-1, VCAM-1, MCP-1 and galectin-3 at 3 months (all P < 0.05) but not at 7 days after PCI (P > 0.05). At 3 months, the STDP group had lower PMP number ([42.9 ± 37.3] vs. [67.8 ± 53.1] counts/μL in the control group, P = 0.05). Subgroup analysis showed that STDP increased percentage inhibition of ADP-induced platelet aggregation only in slow metabolizers (66.0% ± 20.8% in STDP group vs. 36.0% ± 28.1% in the control group, P < 0.05), but not in intermediate or fast metabolizers. The rate of MACEs during the 3-month follow-up did not differ between the two groups.@*CONCLUSION@#STDP produced antiplatelet, anti-inflammatory and cardioprotective effects. Subgroup analysis indicated that STDP inhibited residual platelet reactivity in slow metabolizers only.@*TRIAL REGISTRATION@#This study was registered on www.chictr.org.cn: ChiCTR-IPR-16009785.

Protective effects of scutellarin on diabetic cardiomyopathy in mice / 药学学报

To investigate the effect of scutellarin (Scu) on diabetic cardiomyopathy in mice, type 2 diabetes mellitus was induced by intraperitoneal injection of 50 mg∙kg-1 streptozotocin (STZ) into a high-fat diet. Scu was injected intraperitoneally. After 8 weeks, fasting blood glucose and serum biochemical parameters were measured. Masson staining was performed on myocardial tissue. The expression levels of Nrf2, NFκB, AKT and p-AKT in myocardium of mice were observed by Western blot. All the procedures were approved by the Laboratory Animal Ethics Committee of the Peking Union Medical College. The results showed that Scu significantly decreased the heart-body ratio, increased myocardial contractile function, decreased the level of myocardial fibrosis and the expression of collagen I and collagen III in myocardium of diabetic mice. Scu can effectively reduce the levels of lactate dehydrogenase (LDH), creatine kinase isoenzyme (CK-MB), malondialdehyde (MDA) in serum of diabetic mice, increase the level of antioxidant enzymes in serum, and inhibit the release of inflammatory factors. Further studies showed that Scu significantly increased Nrf2 nuclear translocation, inhibited NFκB nuclear translocation and increased AKT phosphorylation. It indicates that Scu has significant effect on diabetic cardiomyopathy in mice.

What do caregivers value and is there agreement in perception of met needs between nurses and caregivers?

INTRODUCTION@#There is an increasing reliance on informal caregivers to continue the care of patients after discharge. This is a huge responsibility for caregivers and some may feel unprepared for the role. Without adequate support and understanding regarding their needs, patient care may be impeded. This study aimed to identify the needs valued by caregivers and if there was agreement between acute care nurses and caregivers in the perception of whether caregiver needs were being met.@*METHODS@#We conducted face-to-face interviews with 100 pairs of acute care nurses and caregivers. Participants were recruited from inpatient wards through convenience sampling. Questionnaires included demographic data of nurses and caregivers, patients' activities of daily living, and perception of caregiver needs being met in six domains of care. Independent t-test was used to compare mean values in each domain, and intraclass correlation coefficient was used to compare agreement in perception.@*RESULTS@#Caregivers valued reassurance the most. Three domains of care needs showed significant differences in perception of caregiver needs being met:reassurance (p = 0.002), honesty and timeliness (p = 0.008), and kindness and genuine care (p = 0.026). There was poor agreement in all six domains of caregiver needs being met between nurses and caregivers.@*CONCLUSION@#Although caregivers valued reassurance the most, there was poor agreement between acute care nurses and caregivers in the perception of caregiver needs being met. Hence, more attention should be paid to the caregiver's needs. Further studies can examine reasons for unmet caregiver needs and interventions to improve support for them.

This method was used for the neurotransmitters detection in rat adrenal, blood and hypothalamus. The samples were pre-column derivatized with dansyl chloride,and 5-HTP and CA were used as internal standards. A Thermo C18column (50 mm×3 mm,2.7 μm) was used for sample separation with 0.1% aqueous formic acid solution as phase A and methanol as phase B at a flow rate of 0.2 mL/min, and the injection volume was set at 2 μL. The detection was carried out with multi-reaction monitoring(MRM) in electron spray ionization (ESI) positive mode. The linear ranges for detection of GABA,5-HT, L-Tyr, DA, NE and E were 0.26-620.80 μmol/L,0.03-11.20 μmol/L,1.20-88.00 μmol/L,0.03-41.02 μmol/L, 0.01-47.20 μmol/L, 0. 01-90. 24 μmol/L, respectively, with recoveries varying from 91. 16% to 116.20%. This method can detect the neurotransmitters rapidly and accurately, providing a platform for the determination of neurotransmitters in rat plasma, adrenal gland and hypothalamus in pharmacological experiments.
