RESUMO

OBJECTIVE: To observe the angiogenesis effect of electroacupuncture (EA) at Shuigou acupoint (GV 26) in the treatment of cerebral ischemia, and explore the value of miRNA-7 (miR-7) in it. METHODS: First, 48 mice were randomly divided into sham operation, middle cerebral artery occlusion (MCAO) model, and EA treatment groups. Then 9 mice were divided into carrier control group, miR-7 knockout group and miR-7 overexpression group (n=3 each group). Finally, 20 mice were divided into model and carrier control group, model and miR-7 knockout group, EA treatment and carrier control group and EA treatment and miR-7 overexpression group, with 3-6 mice in each group. The MCAO model was established in the MCAO and EA groups. Neurological deficit score and 2,3,5-triphenyltetrazolium chloride (TTC) staining were used to evaluate the severity of cerebral ischemia. Hematoxylin-eosin staining was used to describe basic pathological changes. Immunohistochemistry was used to quantify cerebral microvessel density. Real-time PCR and Western blot were used to detect the expression of miR-7 and its downstream target genes Krüppel-like factor 4/vascular endothelial growth factor (KLF4/VEGF) and angiopoietin-2 (ANG-2) in the ischemic cerebral cortex. RESULTS: After EA, neurological deficit scores and infarction volumes decreased, and the density of cerebral microvessels increased. In the MCAO group, miR-7 expression was higher than that in the sham group (P<0.01). After EA at GV 26, miR-7 expression decreased (P<0.01) and the expression of downstream target genes KLF4/VEGF and ANG-2 increased as compared with the MCAO group (P<0.01). After EA combined with overexpression of miR-7, the expression of downstream target genes KLF4/VEGF and ANG-2 decreased compared to the control EA group (P<0.01). After miR-7 knockdown, the expression of KLF4/VEGF and ANG-2 increased (P<0.05 or P<0.01). CONCLUSIONS: EA could promote angiogenesis in MCAO mice likely by inhibiting the expression of miR-7 and relieving inhibition of downstream target genes KLF4/VEGF and ANG-2.

RESUMO

The ApoE4 allele is the strongest genetic determinant for Alzheimer's disease (AD), while obesity is a strong environmental risk for AD. The modulatory effect of the ApoE genotype on aging-related cognitive function in tandem with a high-fat diet (HFD) remains uncertain. This study aimed to elucidate the effects of ApoE3/ApoE4 genotypes in aged mice exposed to a HFD, and the benefits of n-3 polyunsaturated fatty acids (PUFAs) from fish oil. Remarkably, the HFD led to weight gain and lipid accumulation, more pronounced in ApoE3 mice, while ApoE4 mice experienced exacerbated cerebral insulin resistance, neuroinflammation, and oxidative stress. Critically, n-3 PUFAs modulated the cerebral insulin signaling via the IRS-1/AKT/GLUT4 pathway, mitigated microglial hyperactivity, and reduced IL-6 and MDA levels, thereby counteracting cognitive deficits. These findings highlight the contrasting impacts of ApoE genotypes on aging mice exposed to a HFD, supporting n-3 PUFAs as a strategic nutritional intervention for brain health, especially for ApoE4 carriers.

RESUMO

OBJECTIVE: To evaluate the efficacy and safety of Huashi Baidu Granules (HSBD) in treating patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant. METHODS: A single-center retrospective cohort study was conducted during COVID-19 Omicron epidemic in the Mobile Cabin Hospital of Shanghai New International Expo Center from April 1st to May 23rd, 2022. All COVID-19 patients with asymptomatic or mild infection were assigned to the treatment group (HSBD users) and the control group (non-HSBD users). After propensity score matching in a 1:1 ratio, 496 HSBD users of treatment group were matched by propensity score to 496 non-HSBD users. Patients in the treatment group were administrated HSBD (5 g/bag) orally for 1 bag twice a day for 7 consecutive days. Patients in the control group received standard care and routine treatment. The primary outcomes were the negative conversion time of nucleic acid and negative conversion rate at day 7. Secondary outcomes included the hospitalized days, the time of the first nucleic acid negative conversion, and new-onset symptoms in asymptomatic patients. Adverse events (AEs) that occurred during the study were recorded. Further subgroup analysis was conducted in vaccinated (378 HSBD users and 390 non-HSBD users) and unvaccinated patients (118 HSBD users and 106 non-HSBD users). RESULTS: The median negative conversion time of nucleic acid in the treatment group was significantly shortened than the control group [3 days (IQR: 2-5 days) vs. 5 days (IQR: 4-6 days); P<0.01]. The negative conversion rate of nucleic acid in the treatment group were significantly higher than those in the control group at day 7 (91.73% vs. 86.90%, P=0.014). Compared with the control group, the hospitalized days in the treatment group were significantly reduced [10 days (IQR: 8-11 days) vs. 11 days (IQR: 10.25-12 days); P<0.01]. The time of the first nucleic acid negative conversion had significant differences between the treatment and control groups [3 days (IQR: 2-4 days) vs. 5 days (IQR: 4-6 days); P<0.01]. The incidence of new-onset symptoms including cough, pharyngalgia, expectoration and fever in the treatment group were lower than the control group (P<0.05 or P<0.01). In the vaccinated patients, the median negative conversion time and hospitalized days were significantly shorter than the control group after HSDB treatment [3 days (IQR: 2-5 days) vs. 5 days (IQR: 4-6 days), P<0.01; 10 days (IQR: 8-11 days) vs. 11 days (IQR: 10-12 days), P<0.01]. In the unvaccinated patients, HSBD treatment efficiently shorten the median negative conversion time and hospitalized days [4 days (IQR: 2-6 days) vs. 5 days (IQR: 4-7 days), P<0.01; 10.5 days (IQR: 8.75-11 days) vs. 11.0 days (IQR: 10.75-13 days); P<0.01]. No serious AEs were reported during the study. CONCLUSION: HSBD treatment significantly shortened the negative conversion time of nuclear acid, the length of hospitalization, and the time of the first nucleic acid negative conversion in patients infected with SARS-COV-2 Omicron variant (Trial registry No. ChiCTR2200060472).

RESUMO

BACKGROUND: Ventricular remodeling after acute anterior wall ST-segment elevation myocardial infarction (AAMI) is an important factor in occurrence of heart failure which additionally results in poor prognosis. Therefore, the treatment of ventricular remodeling needs to be further optimized. Compound Danshen Dripping Pills (CDDP), a traditional Chinese medicine, exerts a protective effect on microcirculatory disturbance caused by ischemia-reperfusion injury and attenuates ventricular remodeling after myocardial infarction. OBJECTIVE: This study is designed to evaluate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function after AAMI on a larger scale. METHODS: This study is a multi-center, randomized, double-blind, placebo-controlled, parallel-group clinical trial. The total of 268 patients with AAMI after primary percutaneous coronary intervention (pPCI) will be randomly assigned 1:1 to the CDDP group (n=134) and control group (n=134) with a follow-up of 48 weeks. Both groups will be treated with standard therapy of ST-segment elevation myocardial infarction (STEMI), with the CDDP group administrating 20 tablets of CDDP before pPCI and 10 tablets 3 times daily after pPCI, and the control group treated with a placebo simultaneously. The primary endpoint is 48-week echocardiographic outcomes including left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume index (LVEDVI), and left ventricular end-systolic volume index (LVESVI). The secondary endpoint includes the change in N terminal pro-B-type natriuretic peptide (NT-proBNP) level, arrhythmias, and cardiovascular events (death, cardiac arrest, or cardiopulmonary resuscitation, rehospitalization due to heart failure or angina pectoris, deterioration of cardiac function, and stroke). Investigators and patients are both blinded to the allocated treatment. DISCUSSION: This prospective study will investigate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function in patients undergoing pPCI for a first AAMI. Patients in the CDDP group will be compared with those in the control group. If certified to be effective, CDDP treatment in AAMI will probably be advised on a larger scale.

RESUMO

OBJECTIVE: To assess the effect and safety of Reyanning Mixture (RYN) in treating asymptomatic or mild severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children and adolescents. METHODS: This is a prospective, open-label, randomized controlled trial. Patients aged 1-17 years and diagnosed with asymptomatic or mild coronavirus disease-2019 (COVID-19) were assigned to an intervention group (RYN plus standard care) and a control group (standard care) according to a randomization list. The primary outcomes were SARS-CoV-2 negative conversion time. Secondary outcomes included negative conversion rate on days 3 and 7, hospital length of stay, symptom relief rate, new-onset symptoms of asymptomatic infected patients, and progressive disease rate. The cycle threshold (Ct) values of ORF1ab or N genes were also tested. RESULTS: A total of 214 patients in the intervention group and 217 in the control group were analyzed. The SARS-CoV-2 negative conversion time was significantly shortened in the intervention group [5 days (interquartile range (IQR): 5-6) vs. 7 days (IQR: 6-7), P<0.01]. By days 3 and 7, the negative conversion rates were significantly higher in the intervention group (day 3: 32.7% vs. 21.2%, P=0.007; day 7: 75.2% vs. 60.8%, P=0.001). Ct values significantly increase on day 2 [ORF1ab gene: 35.62 (IQR: 29.17-45.00) vs. 34.22 (IQR: 28.41-39.41), P=0.03; N gene: 34.97 (IQR: 28.50-45.00) vs. 33.51 (IQR: 27.70-38.25), P=0.024] and day 3 [ORF1ab gene: 38.00 (IQR: 32.72-45.00) vs. 35.81 (IQR: 29.96-45.00), P=0.003; N gene: 37.16 (IQR: 32.01-45.00) vs. 35.26 (IQR: 29.09-45.00), P=0.01]. No significant difference was found in hospital length of stay between the two groups (P>0.05). Symptoms of cough were significantly improved (82.2% vs. 70.0%, P=0.02) and wheezing was significantly reduced (0.7% vs. 12.9%, P<0.01) in the intervention group compared with the control group. During the trial, no disease progression or serious adverse events were reported. CONCLUSION: Adding RYN to standard care may be a safe and effective treatment for children with asymptomatic and mild SARS-CoV-2 infection. (Registration No. ChiCTR2200060292).

RESUMO

Sepsis has emerged as a major global public health concern due to its elevated mortality and high cost of care. This study aimed to evaluate the risk factors associated with the mortality of sepsis patients in the Intensive Care Unit (ICU), and to intervene in the early stages of sepsis in order to improve patient outcomes and reduce mortality. From January 1st, 2021 to December 31st, 2021, Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Huashan Hospital Affiliated to Fudan University, and The Seventh People's Hospital Affiliated to Shanghai University of Traditional Chinese Medicine were designated as sentinel hospitals, and sepsis patients in their respective ICU and Emergency ICU were selected as research subjects, and divided into survivors and non-survivors according to their discharge outcomes. The mortality risk of sepsis patients was subsequently analyzed by logistic regression. A total of 176 patients with sepsis were included, of which 130 (73.9%) were survivors and 46 (26.1%) were non-survivors. Factors identified as having an impact on death among sepsis patients included female [Odds Ratio (OR) = 5.135, 95% confidence interval (CI): 1.709, 15.427, P = .004)], cardiovascular disease (OR = 6.272, 95% CI: 1.828, 21.518, P = .004), cerebrovascular disease (OR = 3.133, 95% CI: 1.093, 8.981, P = .034), pulmonary infections (OR = 6.700, 95% CI: 1.744, 25.748, P = .006), use of vasopressors (OR = 34.085, 95% CI: 10.452, 111.155, P < .001), WBC < 3.5 × 109/L (OR = 9.752, 95% CI: 1.386, 68.620, P = .022), ALT < 7 U/L (OR = 7.672, 95% CI: 1.263, 46.594, P = .027), ALT > 40 U/L (OR = 3.343, 95% CI: 1.097, 10.185, P = .034). Gender, cardiovascular disease, cerebrovascular disease, pulmonary infections, the use of vasopressors, WBC, and ALT are important factors in evaluating the prognostic outcome of sepsis patients in the ICU. This suggests that medical professionals should recognize them expeditiously and implement aggressive treatment tactics to diminish the mortality rate and improve outcomes.

RESUMO

In the face of the alarming rise in global antimicrobial resistance, only a handful of novel antibiotics have been developed in recent decades, necessitating innovations in therapeutic strategies to fill the void of antibiotic discovery. Here, we established a screening platform mimicking the host milieu to select antibiotic adjuvants and found three catechol-type flavonoids-7,8-dihydroxyflavone, myricetin, and luteolin-prominently potentiating the efficacy of colistin. Further mechanistic analysis demonstrated that these flavonoids are able to disrupt bacterial iron homeostasis through converting ferric iron to ferrous form. The excessive intracellular ferrous iron modulated the membrane charge of bacteria via interfering the two-component system pmrA/pmrB, thereby promoting the colistin binding and subsequent membrane damage. The potentiation of these flavonoids was further confirmed in an in vivo infection model. Collectively, the current study provided three flavonoids as colistin adjuvant to replenish our arsenals for combating bacterial infections and shed the light on the bacterial iron signaling as a promising target for antibacterial therapies.

RESUMO

BACKGROUND: Lianhua Qingwen Granules or Capsules (LHQW) has accumulated much research evidence in the fight against the coronavirus disease 2019 (COVID-19) epidemic. However, there are still few data on its efficacy and safety in children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. PURPOSE: To evaluate the efficacy and safety of LHQW in children with SARS-CoV-2 Omicron infection. METHODS: We conducted a single-center, propensity-score matched retrospective cohort study of children with SARS-CoV-2 Omicron infection in Shanghai New International Expo Center mobile cabin hospital between April 1st and June 1st, 2022. Eligible patients received either LHQW granules/capsules plus supportive care (LHQW group) or supportive care alone (control group). The primary outcome was the negative conversion time of nucleic acid. Secondary outcomes included the negative conversion rate of nucleic acid, the length of hospital stay, clinical disease progression, and cycle threshold [Ct] values for SARS-CoV-2 open reading frame [ORF1ab] or nucleocapsid [N] genes. RESULTS: Overall, 2808 patients were enrolled, and 346 patients in each group were included in the analysis. Among the propensity-score matched groups, LHQW treatment was associated with an accelerated negative conversion time of nucleic acid (median: 5 d vs. 6 d, Hazard ratio: 1.25, 95% CI: 1.08 - 1.46, Log-rank p < 0.001), a higher negative conversion rate of nucleic acid (Day 2 - 6: 2.9% vs. 0.6%, p = 0.036; 29.8% vs. 5.5%, p < 0.001; 42.5% vs. 24.3%, p < 0.001; 51.4% vs. 31.5%, p < 0.001; 63.3% vs. 55.2%, p = 0.030), shorter hospital stay (median: 10 d vs. 11 d, Hazard ratio: 1.50, 95% CI: 1.29 - 1.74, Log-rank p < 0.001), and lower rates of asymptomatic infection progressing to mild (37.9% vs. 46.5%, p = 0.021). CONCLUSION: Our study suggested that LHQW treatment was associated with faster clinical recovery in children with SARS-CoV-2 Omicron infection.

RESUMO

Novel highly hydrophilic and biocompatible bismuth nanospheres with gold nanoparticles growing outside (Bi@Au nano-acanthospheres, Bi@Au NASs) were synthesized through a simple procedure, which demonstrated to be a promising photothermal agent owing to the ultrahigh photothermal conversion efficiency (η = 46.6 %). The as-prepared Bi@Au NASs showed excellent blood compatibility and fairly low cytotoxicity to human lung cancer A549 cells, as well as efficient photothermal ablation (PTA) therapy induced by a near-infrared laser. Under the 808 nm laser radiation, the tumour temperature could be elevated by ∼25 °C high enough to kill the cancer cells. Moreover, the anticancer drug doxorubicin hydrochloride (DOX) was successfully loaded in Bi@Au NASs with a loading content as high as 16.78 % and released under a pH sensitive release profile, a characteristic beneficial for intravenous delivery of DOX into cancer cells for chemotherapy. The presence of the Bi element enabled Bi@Au NASs to act as a favourable computed tomography (CT) contrast medium for CT imaging-guided tumour treatment. Compared with cancer treatment through either photothermal therapy or chemotherapy, the chemo-photothermal synergistic therapy using Bi@Au NASs as both a photothermal agent and a drug carrier has efficiently enhanced the in vitro and in vivo therapeutic effects in cancer treatment.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: JinHong Formula (JHF) was derived from the famous Rhubarb and Moutan Decoction which was prescribed for appendicitis. It was originally recorded in the classic of "Jingui Yaolve" written by Zhang Zhongjing. It is a kind of traditional Chinese medicine, widely used in the treatment of inflammation. However, the clinical effect of JHF for sepsis and its comprehensive mechanism in sepsis remained largely unknown. RESEARCH PURPOSE: The aim of our study was to evaluate the clinical effect of JHF in the treatment of sepsis, and to explore its mechanism from the perspective of network pharmacology. RESEARCH METHODS: The single-center randomized clinical trial was conducted to assess the effect of JHF in the treatment of sepsis. Additionally, we used the Chinese herbal medicine pharmacology database and analysis platform to identify the active components and therapeutic target of JHF. Numerous well-known disease target databases have been used to screen therapeutic target proteins for sepsis. Furthermore, we have established a Protein-Protein Interaction (PPI) network and carried out Gene Onotology/Kyoto Encyclopedia of Genes and Genomes (GO/KEGG) enrichment analysis. In order to conclude which active compounds from JHF may be responsible for signaling pathway, we performed network analysis. RESEARCH RESULTS: The study included 114 patients. By comparing participants with and without JHF, the results suggested that JHF significantly reduced all-cause mortality on 28 and 60 days after intervention, and improved Sequential Organ Failure Assessment (SOFA) on 7th day after intervention as well as. JHF had an effect of anti-inflammatories and antioxidants (SOD). By using network pharmacological analysis, we identified 72 active components and 426 target genes of JHF, and successfully constructed a "JHF-compound target-sepsis" network. 116 mentioned targets revealed by GO/KEGG enrichment analysis played a significant role in the inflammatory reaction and immunoregulation via interleukin-17 (IL-17) and tumor necrosis factor (TNF) signaling pathway. Moreover, the analysis of "pathway target-active component" revealed that Sennidin A, Rheidin A, Rheidin B, Rheidin C, (E)-4-Phenyl-3-Buten-2-One, Osmanthuside H, Esculetin, and Caffeicacid were responsible for IL-17, TNF signaling pathways. CONCLUSION: JHF contains potential active substance of anti-inflammatory and antioxidant. These active compounds may come into play through IL-17 and TNF signaling pathways. For sepsis, JHF may be a promising and effective treatment strategy.

RESUMO

BACKGROUND: A wave of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant rapidly resulted in a steep increase in the infected population and an overloaded healthcare system. Effective medications for Omicron are currently limited. The previous observational study supports the efficacy and safety of Reyanning (RYN) mixture in the treatment of coronavirus disease 2019 (COVID-19). PURPOSE: To evaluate the efficacy of RYN in asymptomatic and mildly infected patients with SARS-CoV-2 infection. STUDY DESIGN AND METHODS: This study was a prospective, open-label, randomized controlled trial. We consecutively recruited 2830 patients from Shanghai New International Expo Center mobile cabin hospital and randomized them in a 1:1 ratio to receive RYN plus standard care or receive standard care alone. The primary outcomes were the negative conversion of nucleic acid. Secondary outcomes included the hospital duration, new-onset symptoms, proportion of disease progression, and the viral load measured by the cycle threshold (Ct) value. RESULTS: A total of 1393 patients in the intervention group and 1407 patients in the control group completed the study. The negative conversion time of nucleic acid was significantly shortened in the intervention group (median: 6 d vs. 7 d, Hazard ratio: 0.768, 95CI %: 0.713-0.828, p < 0.0001). The negative conversion rate of nucleic acid was significantly higher in the intervention group (Day 3: 32.4% vs. 18.3%; Day7: 65.3% vs. 55.2%, p < 0.001). The hospitalization duration was significantly shortened in the intervention group (median: 8 d vs. 9 d, Hazard ratio: 0.759, 95% CI: 0.704-0.818, p < 0.0001). The proportion of new-onset fever (2.4% vs. 4.1%, p = 0.012), coughing (12.2% vs. 14.8%, p = 0.046), and expectoration (6.0% vs. 8.0%, p = 0.032) in the intervention group was significantly lower. RYN treatment increased Ct values and reduced the viral load. No disease progression and serious adverse events were reported during the study. CONCLUSION: RYN is a safe and effective treatment that can accelerate virus clearance and promote disease recovery in asymptomatic and mild Omicron infections.

RESUMO

OBJECTIVE: Severe cases of coronavirus disease 2019 (COVID-19) are expected to have a worse prognosis than mild cases. Shenhuang Granule (SHG) has been shown to be a safe and effective treatment for severe COVID-19 in a previous randomized clinical trial, but the active chemical constituents and underlying mechanisms of action remain unknown. The goal of this study is to explore the chemical basis and mechanisms of SHG in the treatment of severe COVID-19, using network pharmacology. METHODS: Ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry was employed to screen chemical constituents of SHG. Putative therapeutic targets were predicted by searching traditional Chinese medicine system pharmacology database and analysis platform, SwissTargetPrediction, and Gene Expression Omnibus (GEO) databases. The target protein-protein interaction network and enrichment analysis were performed to investigate the hub genes and presumptive mechanisms. Molecular docking and molecular dynamics simulations were used to verify the stability and interaction between the key chemical constituents of SHG and COVID-19 protein targets. RESULTS: Forty-five chemical constituents of SHG were identified along with 131 corresponding therapeutic targets, including hub genes such as HSP90AA1, MMP9, CXCL8, PTGS2, IFNG, DNMT1, TYMS, MDM2, HDAC3 and ABCB1. Functional enrichment analysis indicated that SHG mainly acted on the neuroactive ligand-receptor interaction, calcium signaling pathway and cAMP signaling pathway. Molecular docking showed that the key constituents had a good affinity with the severe acute respiratory syndrome coronavirus 2 protein targets. Molecular dynamics simulations indicated that ginsenoside Rg4 formed a stable protein-ligand complex with helicase. CONCLUSION: Multiple components of SHG regulated multiple targets to inhibit virus invasion and cytokine storm through several signaling pathways; this provides a scientific basis for clinical applications and further experiments.

RESUMO

Importance: Electroacupuncture (EA) is a widely recognized therapy for depression and sleep disorders in clinical practice, but its efficacy in the treatment of comorbid insomnia and depression remains uncertain. Objective: To assess the efficacy and safety of EA as an alternative therapy in improving sleep quality and mental state for patients with insomnia and depression. Design, Setting, and Participants: A 32-week patient- and assessor-blinded, randomized, sham-controlled clinical trial (8-week intervention plus 24-week observational follow-up) was conducted from September 1, 2016, to July 30, 2019, at 3 tertiary hospitals in Shanghai, China. Patients were randomized to receive EA treatment and standard care, sham acupuncture (SA) treatment and standard care, or standard care only as control. Patients were 18 to 70 years of age, had insomnia, and met the criteria for depression as classified in the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition). Data were analyzed from May 4 to September 13, 2020. Interventions: All patients in the 3 groups were provided with standard care guided by psychiatrists. Patients in the EA and SA groups received real or sham acupuncture treatment, 3 sessions per week for 8 weeks, for a total of 24 sessions. Main Outcomes and Measures: The primary outcome was change in Pittsburgh Sleep Quality Index (PSQI) from baseline to week 8. Secondary outcomes included PSQI at 12, 20, and 32 weeks of follow-up; sleep parameters recorded in actigraphy; Insomnia Severity Index; 17-item Hamilton Depression Rating Scale score; and Self-rating Anxiety Scale score. Results: Among the 270 patients (194 women [71.9%] and 76 men [28.1%]; mean [SD] age, 50.3 [14.2] years) included in the intention-to-treat analysis, 247 (91.5%) completed all outcome measurements at week 32, and 23 (8.5%) dropped out of the trial. The mean difference in PSQI from baseline to week 8 within the EA group was -6.2 (95% CI, -6.9 to -5.6). At week 8, the difference in PSQI score was -3.6 (95% CI, -4.4 to -2.8; P < .001) between the EA and SA groups and -5.1 (95% CI, -6.0 to -4.2; P < .001) between the EA and control groups. The efficacy of EA in treating insomnia was sustained during the 24-week postintervention follow-up. Significant improvement in the 17-item Hamilton Depression Rating Scale (-10.7 [95% CI, -11.8 to -9.7]), Insomnia Severity Index (-7.6 [95% CI, -8.5 to -6.7]), and Self-rating Anxiety Scale (-2.9 [95% CI, -4.1 to -1.7]) scores and the total sleep time recorded in the actigraphy (29.1 [95% CI, 21.5-36.7] minutes) was observed in the EA group during the 8-week intervention period (P < .001 for all). No between-group differences were found in the frequency of sleep awakenings. No serious adverse events were reported. Conclusions and Relevance: In this randomized clinical trial of EA treatment for insomnia in patients with depression, quality of sleep improved significantly in the EA group compared with the SA or control group at week 8 and was sustained at week 32. Trial Registration: ClinicalTrials.gov Identifier: NCT03122080.

RESUMO

OBJECTIVE: To analyze the clinical characteristics and prognosis of patients infected with novel coronavirus Omicron variant in Shanghai, as to provide a reference for epidemic prevention, clinical diagnosis, and treatment. METHODS: Altogether 4 264 novel coronavirus Omicron variant-infected patients with positive results of nucleic acid admitted to Shanghai New International Expo Center N3 Mobile Cabin Hospital from April 2 to May 7, 2022, were included. The demographic and baseline clinical characteristics, treatment strategy, prognosis, and different factors affecting the length of hospital stay were analyzed. RESULTS: A total of 4 264 novel coronavirus variant Omicron-infected cases were collected, including 3 111 cases (73.0%) asymptomatic infections and 1 153 cases (27.0%) mild infections. The overall median age was 45 (33, 55) years old with a range from 2 years old to 81 years old. The male to female ratio was 1.37:1. Altogether 3 305 cases (77.5%) had been vaccinated, of which 3 166 cases completed more than 2 doses. The upper respiratory tract symptoms such as cough and expectoration were the most common clinical manifestations of these infected patients. During the course of the disease, patients with asymptomatic infection were mainly treated with traditional Chinese medicine (TCM, 55.1%) and clinical observation (36.8%), and those with mild infection were mainly treated with TCM (42.2%) or integrated Chinese and Western medicine (30.4%). All patients were cured and discharged. The overall median length of hospital stay and the negative conversion time of nucleic acid were 9 (6, 10) days and 8 (5, 9) days, respectively. Compared with the asymptomatic infected patients, the hospitalization duration and the nucleic acid negative conversion time of the mildly infected patients were slightly longer [days: 10 (8, 11) vs. 9 (5, 10); 8 (6, 10) vs. 7 (4, 9), both P < 0.001]. Multiple linear regression analysis showed that the increasing age and mild infection were associated with longer hospitalization duration, and the treatment of TCM or integrated Chinese and Western medicine was associated with shortened length of hospital stay (all P < 0.05). CONCLUSIONS: The current novel coronavirus Omicron variant epidemic in Shanghai mainly caused asymptomatic and mild infections. The young and middle-aged population had a relatively high infection rate. The upper respiratory tract symptoms such as cough and expectoration were the most common clinical symptoms. Elderly and confirmed patients had prolonged hospitalization duration, while for patients receiving TCM treatment, the hospitalization duration was shortened.

RESUMO

OBJECTIVE: To evaluate the effectiveness and safety of Baidu Jieduan Granules (BDJDG) to treat common type coronavirus disease 2019 (COVID-19). METHODS: This multicenter, retrospective, and observational clinical trial included 230 common COVID-19 patients in Leishenshan, Huangshi, and Laohekou Hospitals in Wuhan from January 21 to March 26, 2020. The included patients were further divided into two subgroups according to the use of supplemental oxygen, mild and moderate groups. During the first 14 d of hospitalization, all patients were administered BDJDG combined with conventional Western medicine, and observed for continuous 28 d. Primary outcomes were disease progression rate and discharge rate. Secondary outcomes included negative conversion time of nucleic acid, hospitalization duration, clinical symptom subsidence time, and symptom regression rate. RESULTS: A total of 230 common COVID-19 patients were analyzed (138 in moderate group and 92 in mild group). By day 28, the disease progression rate was 4.3% and the discharge rate was 95.7%. All mild cases recovered and were discharged from hospital. The median negative conversion time of nucleic acid of all 230 COVID-19 patients was 12 d [inter-quartile range (IQR) 3.5-17], the median hospitalization duration was 15 d (IQR 12-20). The median time to fever, cough, and fatigue recovery was 4 d (IQR 2-6), 8 d (IQR 5-12), and 8 d (IQR 5-11). The recovery rate of fever, cough, and fatigue was 94.6%, 90.5%, and 93.5%. The median time to clinical improvement was 12 d (IQR 10-17). Compared with the baseline, total leukocyte counts, neutrophil counts, lymphocyte counts, and platelet counts were increased significantly on days 7 and 14 (P<0.01). C-reactive protein markedly increased on day 3 and significantly decreased on days 7 and 14 (P<0.01). No serious adverse events occurred during treatment. CONCLUSION: BDJDG may be effective and safe for treatment of common type COVID-19. (Registration No. ChiCTR2000030836).

RESUMO

BACKGROUND AND AIM: Presently, over-the-counter drugs that can treat upper respiratory tract infections (URTI) are rarely effective and safe. Chaiqin Qingning Capsule (CQQNC), a Chinese patent medicine, which has been verified by long-term clinical practice is recommended by Chinese experts for the treatment of URTI with fever. This study conducted a prospective, double-blinded, randomized, multicenter controlled trial to evaluate the effectiveness and safety of CQQNC in the treatment of URTI. METHODS: The study was conducted at 4 clinical centers in China. Eligible subjects were recruited and randomized 1:1 to the CQQNC group and Qingkailing Capsule (QKLC) group. Both groups were administered orally three times a day for three consecutive days. Primary outcomes were the antipyretic onset time and the temperature recovery time. Secondary outcomes included the symptom disappearance rate, symptom score, and drug safety assessment. RESULTS: A total of 269 subjects were analyzed (134 subjects in the CQQNC group, 135 subjects in the QKLC group). The antipyretic onset time and the temperature recovery time were significantly shortened in the CQQNC group (median: 5 h vs. 10 h, p < 0.0001, median: 19 h vs. 27 h, p < 0.0001). CQQNC was more effective than the QKLC in improving the symptoms of pharyngodynia and rhinobyon (85.07% vs. 71.11%, p = 0.008; 76.99% vs. 64.41%, p = 0.043), and in improving the overall symptom scores (-15.10 ± 3.23 vs. -13.35 ± 3.58, p < 0.0001). During the trial, no serious adverse events were reported in the two groups. CONCLUSION: CQQNC is effective and safe in the treatment of URTI with fever, and worthy of clinical application.

RESUMO

Sargentodoxa cuneata (Oliv.) Rehd. et Wils is a traditional Chinese medicine to treat acute appendicitis, rheumarthritis, abdominal pain, and painful menstruation for a long history. The investigation of S. cuneata led to the isolation and identification of twenty-three secondary metabolites, including two new compounds, sargentodoxosides A (1) and B (2), and twenty-one known ones (3-23). Their structural characterization was conducted by HRESIMS, 1 D and 2 D NMR spectra. All the isolated compounds were assayed for their agonistic activities against the farnesoid X receptor (FXR). Nine of the isolated compounds displayed significant agonistic effects against FXR at 0.1 µM, suggesting that they could be served as potential agents for the development of FXR agonists.

RESUMO

PURPOSE: A tetrahedron beam (TB) X-ray system with a linear X-ray source array and a linear detector array positioned orthogonal to each other may overcome the X-ray scattering problem of traditional cone-beam X-ray systems. We developed a TB imaging benchtop system using a linear array X-ray source to demonstrate the principle and benefits of TB imaging. METHODS: A multi-pixel thermionic emission X-ray (MPTEX) source with 48 focal spots in 4-mm spacing was developed in-house. The X-ray beams are collimated to a stack of fan beams that are converged to a 6-mm wide multi-row photon-counting detector (PCD). The data collected with a sequential scan of the sources at a fixed view angle were synthesized to a 2D radiography image by a shift-and-add algorithm. The data collected with a full rotation of the system were reconstructed into 3D TB CT (TBCT) images using an Feldkamp, Davis, and Kress (FDK)-based computed tomography (CT) algorithm modified for the TB geometry. RESULTS: With an 18.8-cm long source array and a 35-cm long detector array, the TB benchtop system provides a 25-cm cross-sectional and 8-cm axial field of view (FOV). The scatter-to-primary ratio (SPR) was approximately 17% for TB, as compared with 120% for cone beam geometry. The TBCT system enables reconstructions in two-dimensional radiography and three-dimensional volumetric CT. The TBCT images were free of "cupping" artifacts and have similar image quality as diagnostic helical CT. CONCLUSIONS: A TB imaging benchtop imaging system was successfully developed with MPTEX source and PCD. Phantom and animal cadaver imaging demonstrated that the TB system can produce satisfactory radiographic X-ray images and 3D CT images with image quality comparable to diagnostic helical CTs.

RESUMO

BACKGROUND: Currently, coronavirus disease-2019 (COVID-19) is continuously and rapidly circulating, resulting in serious and extensive effects on human health. Due to the absence of antiviral medicine for COVID-19 thus far, there is a desperate need to develop effective medicine. Traditional Chinese medicine (TCM) has been widely applied in the treatment of epidemic diseases in China, with the aim of achieving clinical efficacy and decreasing the use of antibiotics and glucocorticoids. The aim of this study was to evaluate the efficacy and safety of Baidu Jieduan granules in treating COVID-19. METHODS/DESIGN: This multicentre, open-label, randomized controlled trial will be conducted in 300 patients with COVID-19. The patients will be randomly (1:1) divided into a treatment group and a control group. All patients will receive standard therapy at the same time. Patients in the experimental group will receive Baidu Jieduan granule treatment twice a day for 14 days. The outcomes will be assessed at baseline and at 3, 5, 7 and 14 days after treatment initiation. The primary outcome will be the rate of symptom (fever, fatigue and coughing) recovery. Adverse events (AEs) will be monitored throughout the trial. DISCUSSION: The study will provide high-quality clinical evidence to support the efficacy and safety of Baidu Jieduan granules in the treatment of moderate COVID-19, and enrich the theory and practice of TCM in treating COVID-19.

RESUMO

BACKGROUND: Coronavirus disease 2019 (COVID-19) is still a pandemic, with a high mortality rate in severe/critical cases. Therapies based on the Shenghuang Granule have proved helpful in viral infection and septic shock. HYPOTHESIS/PURPOSE: The objective of the current study was to compare the efficacy and safety of the traditional Chinese medicine, Shenhuang Granule, with standard care in hospitalized patients with severe/critical COVID-19. STUDY DESIGN AND METHODS: This was an open-label, multicenter, randomized, controlled clinical trial. At 4 medical centers, a total of 111 severe/critical patients were randomly assigned to receive Shenhuang Granule (SHG group) twice a day for 14 days, in addition to standard care, or to receive standard care alone (Control group). The maximal follow up time was 75 days. The clinical endpoint was clinical improvement and mortality. RESULTS: 54 patients were assigned to the control group and 57 to the SHG group. The overall mortality was 75.9% (41/54) in the control group, and 38.6% (22/57) in the SHG group (p < 0.01 vs. control). The post hoc analysis showed that in the severe category, the mortality of the control group vs. the SHG group was 58.8% (10/17) vs. 5.3% (1/19) (p < 0.01); while in the critical category, it was 83.8% (31/37) vs. 55.3% (21/38) (p < 0.05). In the severe category, the mortality of patients who eventually received an invasive ventilator in the control vs. the SHG group was 58.8% (10/17) vs. 0 (0/19) (p < 0.01). Administration of SHG was associated with increased lymphocytes and decreased adverse events. CONCLUSION: Shenhuang Granule is a promising integrative therapy for severe and critical COVID-19.
