2-(4-Methylthiazol-5-yl) ethyl nitrate hydrochloride (W1302) is a nitro containing derivative of clomethiazole, which is a novel neuroprotective agent with both carbon monoxide (NO) donor and weak γ-aminobutyric acid type A (GABA_A) receptor allosteric regulatory excitatory effect. The current study used a rat model of transient middle cerebral arteryocclusion (tMCAO) brain injury to evaluate the therapeutic effect of W1302 on ischemic stroke and explore its potential mechanisms of action. This experiment has been reviewed and approved by the Laboratory Animal Management and Use Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences (ethical review forms No. 620, 632, 5013). The results showed that gavage administration of 1, 3, and 10 mg·kg^-1 of W1302 can significantly reduce the volume of cerebral infarction in rats with ischemia for 2 h and reperfusion for 24 h, and the therapeutic effect was better than that of 200 mg·kg^-1 of DL-3n-butylphthalide. W1302 significantly increased NO levels in blood and brain tissue. It increased cerebral blood flow and brain adenosine triphosphate (ATP) content after reperfusion, as well as, inhibited the expressions of inflammatory factors tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in brain tissue. The time window of W1302 was between 120-180 min after ischemia. These research results demonstrated that W1302 could increase NO release, dilate blood vessels, and increase cerebral blood flow, improve energy supply to brain tissue and increase ATP levels, and inhibit neuro-inflammation, which playing the protective roles in tMCAO stroke model rats. This provides theoretical support for the clinical application of W1302 in the treatment of ischemic stroke.

Four new sesquiterpene quinone meroterpenoids, dysideanones F-G (1-2) and dysiherbols D-E (3-4), were isolated from the marine sponge Dysidea avara collected from the South China Sea. The new structures were elucidated by extensive analysis of spectroscopic data including HR-MS and 1D and 2D NMR spectra, and their absolute configurations were assigned by single-crystal X-ray diffraction and ECD calculations. Anti-inflammatory evaluation showed that dysiherbols D-E (3-4) exhibited moderate inhibitory activity on TNF-α-induced NF-κB activation in human HEK-293T cells with IC₅₀ values of 10.2 and 8.6 μmol·L^-1, respectively.

OBJECTIVE: To detect the Epstein-Barr virus (EBV) viral load of children after hematopoietic stem cell transplantation (HSCT) using chip digital PCR (cdPCR). METHODS: The sensitivity of cdPCR was determined using EBV plasmids and the EBV B95-8 strain. The specificity of EBV cdPCR was evaluated using the EBV B95-8 strain and other herpesviruses (herpes simplex virus 1, herpes simplex virus 2, varicella zoster virus, human cytomegalovirus, human herpesvirus 6, and human herpesvirus 7). From May 2019 to September 2020, 64 serum samples of children following HSCT were collected. EBV infection and the viral load of serum samples were detected by cdPCR. The epidemiological characteristics of EBV infections were analyzed in HSCT patients. RESULTS: The limit of detection of EBV cdPCR was 110 copies/mL, and the limit of detection of EBV quantitative PCR was 327 copies/mL for the pUC57-BALF5 plasmid. The result of EBV cdPCR was up to 121 copies/mL in the EBV B95-8 strain, and both were more sensitive than that of quantitative PCR. Using cdPCR, the incidence of EBV infection was 18.75% in 64 children after HSCT. The minimum EBV viral load was 140 copies/mL, and the maximum viral load was 3,209 copies/mL using cdPCR. The average hospital stay of children with EBV infection (184 ± 91 days) was longer than that of children without EBV infection (125 ± 79 days), P = 0.026. CONCLUSION EBV cdPCR had good sensitivity and specificity. The incidence of EBV infection was 18.75% in 64 children after HSCT from May 2019 to September 2020. EBV cdPCR could therefore be a novel method to detect EBV viral load in children after HSCT.

OBJECTIVE: To evaluate the clinical efficacy of Huangqi Sijunzi decoction (HQSJZD) for treating cancer-related fatigue (CRF) of spleen and stomach Qi deficiency type after chemotherapy in patients with breast cancer. METHODS: A total of 94 breast cancer patients who developed CRF of spleen and stomach Qi deficiency type after chemotherapy were randomized into chemotherapy group (n=47) and traditional Chinese medicine (TCM) + chemotherapy group (n=47). The patients in chemotherapy group received the AC or EC regimen and non-drug interventions including psychological counseling, and those in TCM + chemotherapy group received oral administration of HQSJZD in addition to chemotherapy for 21 days as a treatment cycle, after which improvement of fatigue was assessed using Modified Piper Fatigue Scale. The active ingredients and targets of HQSJZD were screened using the TCM System Pharmacology Analysis Platform (TCMSP); the CRF- and breast cancer-related disease targets were retrieved based on data from the GeneCards, NCBI gene and OMIM databases to construct the component-target network and the protein-protein interaction (PPI) network. GO functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes KEGG pathway enrichment analysis of the target genes were performed to construct the component-disease-pathway-target biological network. The binding strength of the major drug ingredients and CRF key targets were predicted using AutoDock software. RESULTS: The scores for somatic fatigue, emotional fatigue and cognitive fatigue, along with the overall fatigue score, showed more significant improvements in TCM+chemotherapy group than in chemotherapy group (P < 0.001), and the response rate reached 89.4% in the combined treatment group. We identified 250 targets for HQSJZD, 2653 CRF-related genes, 15 329 breast cancer-related genes and 161 prescription-disease intersected targets, from which topological analysis identified 66 potential key targets. GO and KEGG enrichment analyses predicted multiple pathways related with the disease. Molecular docking results suggested that the core ingredients of HQSJZD showed high affinities to the key targets AKT1, CASP3, IL6, JUN and VEGFA, among which AKT1 might be the most important target for HQSJZD to treat CRF. CONCLUSION HQSJZD can obviously improve CRF symptoms in breast cancer patients possibly by regulating multiple signaling pathways including PI3K-Akt through AKT1.

Objective: The relationship between outdoor temperature and blood pressure (BP) has been inconclusive. We analyzed data from a prospective cohort study in northwestern China to investigate the effect of outdoor temperature on BP and effect modification by season. Methods: A total of 32,710 individuals who participated in both the baseline survey and the first follow-up in 2011-2015 were included in the study. A linear mixed-effect model and generalized additive mixed model (GAMM) were applied to estimate the association between outdoor temperature and BP after adjusting for confounding variables. Results: The mean differences in systolic blood pressure (SBP) and diastolic blood pressure (DBP) between summer and winter were 3.5 mmHg and 2.75 mmHg, respectively. After adjusting for individual characteristics, meteorological factors and air pollutants, a significant increase in SBP and DBP was observed for lag 06 day and lag 04 day, a 0.28 mmHg (95% Conclusions This study demonstrated a significant negative association between outdoor temperature and BP in a high-altitude environment of northwest China. Moreover, BP showed a significant seasonal variation. The association between BP and temperature differed by season and individuals' demographic characteristics (age, gender, BMI), unhealthy behaviors (smoking and alcohol consumption), and chronic disease status (CVDs, hypertension, and diabetes).

The cross combination of dry-method(network pharmacology analysis) and wet-method(high-resolution mass spectro-metry with antioxidation experiment) was used to predict antioxidant quality markers(Q-markers) of Hippophae tibetana. Ultra-high performance liquid chromatography coupled with hybrid quadrupole-orbitrap mass spectrometry(UPLC-Q-Exactive Orbitrap-MS) was developed to rapidly separate and identify the chemical constituents in H. tibetana. Then in DPPH free radicals and superoxide anion scavenging experiment, the antioxidant activity of the four different polar parts with extracts of petroleumether, ethyl acetate, n-butanol and water was evaluated. Network pharmacology method was used for functional enrichment and pathway analysis to screen antioxidant-related components and preliminarily explain the mechanism of action. On this basis, multi-source information was integrated to predict the antioxidant Q-markers. The results showed that 51 components in H. tibetana were identified, including 18 flavonoids, 14 terpenoids, 6 alkaloids, 4 coumarins and phenylpropanoids, 3 volatile components and 2 polyphenols. The antioxidant capacity of different fractions: ethyl acetate > n-butanol > water > petroleum ether. The medicine mainly acted on PI3 K-Akt and FoxO signaling pathways to perform antioxidant effects through flavonoids such as quercetin, luteolin and kaempferol. According to the results of dry-method and wet-method, quercetin, luteolin and kaempferol, the representatives of poly-hydroxy flavone, may be the antioxidant Q-markers of H. tibetana. In this study, with the antioxidant Q-markers of H. tibetana as an example, an investigation model of predicting Q-marker was discussed based on the ternary system of composition, function and informatics, providing a scientific basis for the establishment of quality evaluation standards for H. tibetana.

Antrodia camphorata, a well-known and highly valued edible medicinal mushroom with intriguing activities like liver protection, has been traditionally used for the treatment of alcoholic liver disease. A. camphorata shows highly medicinal and commercial values with the demand far exceeds the available supply. Thus, the petri-dish cultured A. camphorata (PDCA) is expected to develope as a substitute. In this paper, nineteen triterpenes were isolated from PDCA, and thirteen of them were the unique anthroic acids in A. camphorata, including the main content antcin K, which suggested that PDCA produced a large array of the same anthroic acids as the wild one. Furthermore, no obvious acute toxicity was found suggesting the edible safety of PDCA. In mice alcohol-induced liver injury model, triglyceride (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and malondialdehyde (MDA) had been reduced by the PDCA powder as well as the main content antcin K, which indicated that the PDCA could protect alcoholic liver injury in mice model and antcin K could be the effective component responsible for the hepatoprotective activities of PDCA against alcoholic liver diseases.

Objective: To evaluate the clinical characteristics and survival outcomes of patients with de novo grade 3 or transformed follicular lymphoma (FL). Methods: Fifty-two patients treated at Peking University Cancer Hospital between January 2009 and September 2017 were assessed, including 28 patients with FL 3A grade, 13 patients with FL 3B grade, 11 patients with transformed FL. Baseline characteristics, survival and prognostic factors were analyzed. Results: ① Twenty-six male and 26 female patients were enrolled, including 28 patients with FL 3A grade, 13 patients with FL 3B grade, 11 patients with transformed FL. ②The 3-year progression-free survival (PFS) and overall survival (OS) for the entire cohort were 56.0% and 80.6%, respectively. Patients with international prognostic index (IPI) score 0-1 demonstrated significantly better 3-year PFS (80.3% vs 20.1%; t=18.902, P<0.001) and OS (95.7% vs 57.0%; t=10.406, P<0.001) than patients with IPI score 2-3. Three-year PFS (94.1% vs 37.2% vs 25.2%; P=0.002) and OS (100.0% vs 76.0% vs 59.8%; P=0.020) were also significantly different among patients with FLIPI 1 score 0-1, 2, ≥3. FLIPI 2 score was also identified as a prognostic factor for 3-year PFS (68.4%, 0, 0; P=0.001) and OS(87.5%, 76.2%, 0; P=0.003). ③Multivariate analysis indicated a significant association of PFS (HR=3.536, P=0.015) and OS (HR=15.713, P=0.015) with IPI. FLIPI 2 was associated with OS (score 0-1, HR=0.078, P=0.007; score 2, HR=0.080, P=0.022). Conclusion: De novo grade 3 or transformed FL might be a group of curable disease with current treatment strategies. IPI is still a prognostic tool in this scenario.
