RESUMO
ETHNOPHARMACOLOGICAL RELEVANCE: Artemisia stechmanniana Besser, one of the most prevalent botanical medicines in Chinese, has been traditionally used for hepatitis treatment. However, the bioactive components and pharmacological mechanism on alcohol-induced liver injury remains unclear. AIM OF THE STUDY: To investigate the effect of A. stechmanniana on alcohol-induced liver damage, and further explore its mechanism. MATERIALS AND METHODS: Phytochemical isolation and structural identification were used to determine the chemical constituents of A. stechmanniana. Then, the alcohol-induced liver damage animal and cell model were established to evaluate its hepato-protective potential. Network pharmacology, molecular docking and bioinformatics were integrated to explore the mechanism and then the prediction was further supported by experiments. Moreover, both compounds were subjected to ADMET prediction through relevant databases. RESULTS: 28 compounds were isolated from the most bioactive fraction, ethyl acetate extract A. stechmanniana, in which five compounds (abietic acid, oplopanone, oplodiol, hydroxydavanone, linoleic acid) could attenuate mice livers damage caused by alcohol intragastration, reduce the degree of oxidative stress, and serum AST and ALT, respectively. Furthermore, abietic acid and hydroxydavanone exhibited best protective effect against alcohol-stimulated L-O2 cells injury among five bioactive compounds. Network pharmacology and bioinformatics analysis suggested that abietic acid and hydroxydavanone exhibiting drug likeliness characteristics, were the principal active compounds acting on liver injury treatment, primarily impacting to cell proliferation, oxidative stress and inflammation-related PI3K-AKT signaling pathways. Both of them displayed strong binding energies with five target proteins (HRAS, HSP90AA1, AKT1, CDK2, NF-κB p65) via molecular docking. Western blotting results further supported the predication with up-regulation of protein expressions of CDK2, and down-regulation of HRAS, HSP90AA1, AKT1, NF-κB p65 by abietic acid and hydroxydavanone. CONCLUSION: Alcohol-induced liver injury protection by A. stechmanniana was verified in vivo and in vitro expanded its traditional use, and its two major bioactive compounds, abietic acid and hydroxydavanone exerted hepatoprotective effect through the regulation of PI3K-AKT signaling pathway.

ETHNOPHARMACOLOGY RELEVANCE: Rohdea pachynema F.T.Wang & Tang (R. pachynema), is a traditional folk medicine used for the treatment of stomach pain, stomach ulcers, bruises, and skin infections in China. Some of the diseases may relate to microbial infections in traditional applications. However few reports on its antimicrobial properties and bioactive components. AIM OF THE STUDY: To identify its bioactive constituents against methicillin-resistant Staphylococcus aureus (MRSA) in vitro and in vivo, and its mechanism. MATERIALS AND METHODS: The anti-MRSA ingredient 6α-O-[ß-D-xylopyranosyl-(1 â 3)-ß-D-quinovopyranosyl]-(25S)-5α-spirostan-3ß-ol (XQS) was obtained from R. pachynema by phytochemical isolation. Subsequently, XQS underwent screening using the broth microdilution method and growth inhibition curves to assess its antibacterial activity. The mechanism of XQS was evaluated by multigeneration induction, biofilm resistance assay, scanning electron microscopy, transmission electron microscopy, and metabolomics. Additionally, a mouse skin infection model was established in vivo. RESULTS: 26 compounds were identified from the R. pachynema, in which anti-MRSA spirostane saponin (XQS) was reported for the first time with a minimum inhibitory concentration (MIC) of 8 µg/mL. XQS might bind to peptidoglycan (PGN) of the cell wall, phosphatidylglycerol (PG), and phosphatidylethanolamine (PE) of the cell membrane, then destroying the cell wall and the cell membrane, resulting in reduced membrane fluidity and membrane depolarization. Furthermore, XQS affected MRSA lipid metabolism, amino acid metabolism, and ABC transporters by metabolomics analysis, which targeted cell walls and membranes causing less susceptibility to drug resistance. Furthermore, XQS (8 mg/kg) recovered skin wounds in mice infected by MRSA effectively, superior to vancomycin (8 mg/kg). CONCLUSIONS: XQS showed anti-MRSA bioactivity in vitro and in vivo, and its mechanism association with cell walls and membranes was reported for the first, which supported the traditional uses of R. pachynema and explained its sensitivity to MRSA.

RESUMO
Objective:To compare the efficacy, adverse reactions and skin cosmetic effects between simultaneous integrated boost intensity-modulated radiotherapy and whole-breast intensity-modulated radiotherapy with sequential electronic boost radiotherapy for early breast cancer after breast-conserving surgery.Methods:The clinical data of 96 early breast cancer patients who underwent breast-conserving surgery in Shanxi Province Cancer Hospital from December 2015 to December 2017 were retrospectively analyzed, and the patients were divided into simultaneous integrated boost intensity-modulated radiotherapy group (observation group, 52 cases) and whole-breast intensity-modulated radiotherapy with sequential electronic boost radiotherapy group (control group, 44 cases) according to the postoperative radiotherapy method. In the observation group, the dose division scheme was 50 Gy/25 fractions (2 Gy/fraction) for the whole breast, while 60 Gy/25 fractions (2.4 Gy/fraction) was used in the tumor bed concomitantly, with a total treatment course of 33-35 d. In the control group, the dose division scheme was 50 Gy/25 fractions (2 Gy/ fraction) for the whole breast followed by tumor bed boost of 10 Gy/5 fractions (2 Gy/fraction), with a total treatment course of 40-42 d.Results:Median follow-up time of all patients was 70 months, the 5-year overall survival rates of the observation and control groups were 100.0% and 97.7%, the 5-year local recurrence-free survival rates were 98.1% and 95.5%, the 5-year disease-free survival rates were 98.1% and 93.2%, and the differences between the two groups in terms of overall survival, recurrence-free survival and disease-free survival were not statistically significant ( χ2 = 1.18, P = 0.277; χ2 = 0.44, P = 0.509; χ2 = 1.24, P = 0.265). The incidence of grade 1 and 2 acute radiation dermatitis was 63.5% (33/52) and 19.2% (10/52) in the observation group, and 50.0% (22/44) and 38.6% (17/44) in the control group, there was 1 case (2.3%) of grade 3 acute radiation dermatitis, and the difference between the two groups was statistically significant ( Z = -2.15, P = 0.032). The differences in the incidence of acute and late radiation lung injury between the two groups were not statistically significant (both P > 0.05). Except for 1 patient (2.3%) in the control group with poor cosmetic results, the rest of the patients in both groups achieved average or excellent cosmetic results ( P > 0.05). The radiotherapy time of the observation group was shorter than that of the control group, and the difference was statistically significant ( P = 0.001). Conclusions:Early breast cancer patients who received simultaneous integrated boost intensity-modulated radiotherapy or whole-breast intensity-modulated radiotherapy with sequential electronic boost radiotherapy after breast-conserving surgery could obtain good survival benefit, and the cosmetic results are all good without serious adverse effects. The treatment time of simultaneous integrated boost intensity-modulated radiotherapy is shorter and patient compliance is better.
RESUMO
Chronic inflammation in the airway passage leads to the clinical syndrome of pediatric asthma. Allergic reactions caused by bacterial, viral, and fungal infection lead to the immune dis-balance which primes T helper cells (Th2), a specific cluster of differentiation 4 (CD4) T cell differentiation. This favors the Th2-specific response by activating the inter-leukin 4/interleukin 13 (IL-4/IL-13) cytokine signaling and further activates the secretion of immunoglobulin E (IgE). IL-13 develops bronchial asthma by elevating bronchial hyperresponsiveness and enables production of immunoglobulin M (IgM) and IgE. The present study aims to target IL-13 signaling using molecular docking and understanding molecular dynamic simulation (MDS) to propose a compelling candidate to treat asthma. We developed a library of available allergic drugs (n=20) and checked the binding affinity against IL-13 protein (3BPN.pdb) through molecular docking and confirmed the best pose binding energy of 3.84 and 3.71 for epinephrine and guaifenesin, respectively. Studying the interaction of hydrogen bonds and Van der Walls, it is estimated that electrostatic energy is sufficient to interact with the active site of the IL-13 and has shown to inhibit inflammatory signaling. These computational results confirm epinephrine and guaifenesin as potential ligands showing potential inhibitory activity for IL-13 signaling. This study also suggests the designing of a new ligand and screening of a large cohort of drugs, in the future, to predict the exact mechanism to control the critical feature of asthma (AU)

Objective: To investigate the distribution of HIV-1 genetic subtypes and pretreatment drug resistance (PDR) among men who have sex with men (MSM) from 19 cities of 6 provinces in China. Methods: From April to November 2019, 574 plasma samples of ART-naive HIV-1 infected MSM were collected from 19 cities in Hebei, Shandong, Jiangsu, Zhejiang, Fujian, and Guangdong provinces, total ribonucleic acid (RNA) was extracted and amplified the HIV-1 pol gene region by nested polymerase chain reaction (PCR) after reverse transcription. Then sequences were used to construct a phylogenetic tree to determine genetic subtypes and submitted to the Stanford drug resistance database for drug resistance analysis. Results: A total of 479 samples were successfully amplified by PCR. The HIV-1 genetic subtypes included CRF01_AE, CRF07_BC, B, CRF55_01B, CRF59_01B, CRF65_cpx, CRF103_01B, CRF67_01B, CRF68_01B and unrecognized subtype, which accounted for 43.4%, 36.3%, 6.3%, 5.9%, 0.8%, 0.8%, 0.4%, 0.4%, 0.2% and 5.5%, respectively. The distribution of genetic subtypes among provinces is statistically different (χ2=44.141, P<0.001). The overall PDR rate was 4.6% (22/479), the drug resistance rate of non-nucleoside reverse transcriptase inhibitors, nucleoside reverse transcriptase inhibitors, and protease inhibitors were 3.5% (17/479), 0.8% (4/479) and 0.2% (1/479), respectively. The PDR rate of recent infections was significantly higher than that of long-term infections (χ2=4.634, P=0.031). Conclusions: The HIV-1 genetic subtypes among MSM infected with HIV-1 from 19 cities of 6 provinces in China are diverse, and the distribution of subtypes is different among provinces. The overall PDR rate is low, while the PDR rate of recent infections was significantly higher than that of long-term infections, suggesting the surveillance of PDR in recent infections should be strengthened.

BACKGROUNDSARS-CoV-2 causes COVID-19 through direct lysis of infected lung epithelial cells, which releases damage-associated molecular patterns (DAMPs) and induces a pro-inflammatory cytokine milieu causing systemic inflammation. Anti-viral and anti-inflammatory agents have shown limited therapeutic efficacy. Soluble CD24 (CD24Fc) is able to blunt the broad inflammatory response induced by DAMPs in multiple models. A recent randomized phase III trial evaluating the impact of CD24Fc in patients with severe COVID-19 demonstrated encouraging clinical efficacy. METHODSWe studied peripheral blood samples obtained from patients enrolled at a single institution in the SAC-COVID trial (NCT04317040) collected before and after treatment with CD24Fc or placebo. We performed high dimensional spectral flow cytometry analysis of peripheral blood mononuclear cells and measured the levels of a broad array of cytokines and chemokines. A systems analytical approach was used to discern the impact of CD24Fc treatment on immune homeostasis in patients with COVID-19. FINDINGSTwenty-two patients were enrolled, and the clinical characteristics from the CD24Fc vs. placebo groups were matched. Using high-content spectral flow cytometry and network-level analysis, we found systemic hyper-activation of multiple cellular compartments in the placebo group, including CD8+ T cells, CD4+ T cells, and CD56+ NK cells. By contrast, CD24Fc-treated patients demonstrated blunted systemic inflammation, with a return to homeostasis in both NK and T cells within days without compromising the ability of patients to mount an effective anti-Spike protein antibody response. A single dose of CD24Fc significantly attenuated induction of the systemic cytokine response, including expression of IL-10 and IL-15, and diminished the coexpression and network connectivity among extensive circulating inflammatory cytokines, the parameters associated with COVID-19 disease severity. INTERPRETATIONOur data demonstrates that CD24Fc treatment rapidly down-modulates systemic inflammation and restores immune homeostasis in SARS-CoV-2-infected individuals, supporting further development of CD24Fc as a novel therapeutic against severe COVID-19.

RESUMO
Summary/AbstractFACT (FAcilitates Chromatin Transcription) is a heterodimeric protein complex composed of SUPT16H and SSRP1, and a histone chaperone participating in chromatin remodeling during gene transcription. FACT complex is profoundly regulated, and contributes to both gene activation and suppression. Here we reported that SUPT16H, a subunit of FACT, is acetylated at lysine 674 (K674) of middle domain (MD), which involves TIP60 histone acetyltransferase. Such acetylation of SUPT16H is recognized by bromodomain protein BRD4, which promotes protein stability of SUPT16H. We further demonstrated that SUPT16H-BRD4 associates with histone modification enzymes (EZH2, HDAC1) and affects histone marks (H3K9me3, H3K27me3 and H3ac). BRD4 is known to profoundly regulate interferon (IFN) signaling, while such function of SUPT16H has never been explored. Surprisingly, our results revealed that SUPT16H genetic knockdown via RNAi or pharmacological inhibition by using its inhibitor, curaxin 137 (CBL0137), results in the induction of IFNs and interferon-stimulated genes (ISGs). Through this mechanism, CBL0137 is shown to efficiently inhibit infection of multiple viruses, including Zika, influenza, and SARS-CoV-2. Furthermore, we demonstrated that CBL0137 also causes the remarkable activation of IFN signaling in natural killer (NK) cells, which promotes the NK-mediated killing of virus-infected cells in a co-culture system using human primary NK cells. Overall, our studies unraveled the previously un-appreciated role of FACT complex in regulating IFN signaling in both epithelial and NK cells, and also proposed the novel application of CBL0137 to treat viral infections.

@#BACKGROUND: The study aimed to evaluate the predictive role of interleukin-6 (IL-6) and chronic obstructive pulmonary disease (COPD) assessment test (CAT) score in mechanical ventilation (MV) in COPD patients at the acute exacerbation stage in the emergency department (ED). METHODS: For a one-year period, among adult patients in the ED who met the criteria of acute exacerbation of COPD, 158 who received MV within 48 hours after admission were compared to 294 who didn't require MV within the same period after admission. IL-6 level and CAT score were compared between the two groups. The predicted value of IL-6 and CAT score was assessed by logistic regression analysis and a receiver operating characteristic (ROC) curve. RESULTS: The IL-6 and CAT scores in the 158 MV patients were much higher than those without. IL-6 and CAT scores were independent predictors of MV within 48 hours using logistic regression analysis (IL-6: odds ratio [OR] 1.053, 95% confidence interval [CI] 1.039–1.067, P<0.001; CAT score: OR 1.122, 95% CI 1.086–1.159, P<0.001). The combination of IL-6 and CAT scores (area under ROC curve [AUC] 0.826, 95% CI 0.786–0.866, P<0.001) improved the accuracy of predicting MV within 48 hours when compared with IL-6 (AUC 0.752, 95% CI 0.703–0.800, P<0.001) and CAT scores alone (AUC 0.739, 95% CI 0.692–0.786, P<0.001). The sensitivity and specificity were 69.6%, 74.1%, 75.32% and 63.6%, respectively. CONCLUSION: The combined of IL-6 and CAT scores is useful for evaluating the risk of COPD patients at acute exacerbation in ED, and can provide a predictive value for MV or not within 48 hours.

Objective: To evaluate the clinical efficacy of the Governor Vessel-unblocking and mind-regulating acupuncture method plus repetitive transcranial magnetic stimulation (rTMS) in the treatment of post-stroke insomnia. Methods: A total of 72 patients with post-stroke insomnia were randomly divided into 2 groups, with 36 cases in each group. The control group received rTMS treatment with a frequency of 1 Hz and a motion threshold value of 90%. The observation group received acupuncture with Governor Vessel-unblocking and mind-regulating method based on the rTMS treatment of the control group. The points were Baihui (GV 20), Shenting (GV 24), Yintang (GV 29), Fengfu (GV 16), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6), Shenmai (BL 62) and Zhaohai (KI 6). The treatment was performed once a day for 5 d a week followed by 2 d of rest for 4 weeks. The improvements of Pittsburgh sleep quality index (PSQI), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores were observed after treatment, and the clinical efficacy was compared between the two groups. Results: After 4 weeks of treatment, the PSQI, SAS, and SDS scores of the two groups were all reduced, and the intra-group differences were statistically significant (all P<0.001). After treatment, the three scores in the observation group were all lower than those in the control group, and the differences between the two groups were statistically significant (P<0.05, P<0.05, P<0.001). There was a statistically significant difference between the observation group and the control group comparing the clinical efficacy (P<0.05). Conclusion: The therapeutic effect of the Governor Vessel-unblocking and mind-regulating acupuncture method plus rTMS in treating post-stroke insomnia is better than rTMS alone, and it can better improve the anxiety and depression of patients.
RESUMO
In this study, the alkaline hydrothermal ferric carbon (AHFC), which was prepared by hydrothermal liquefaction method using Fenton iron sludge with NH3·H2O, was used as a skeleton materials for the dewatering of sewage sludge (SS) via thermal hydrolysis. NH2 functional group presented in the AHFC and nano-sized γ-Fe2O3 was anchored on the surface of AHFC. The NH2 functional group notably promoted thermal hydrolysis of SS from the increasing of TOC and TN value. γ-Fe2O3 showed adsorption effect to the water, resulting in decline of the dewatering rate of SS in present condition. When 100% of AHFC was added, dewatering rate of SS was decreased by 19.93% (at 160⯰C), 4.50% (at 180⯰C) and 8.34% (at 200⯰C) respectively. 3D-EEM results showed that the degree of hydrolysis was deepened when AHFC was added for the intensity of soluble microbial products decline. AHFC promoted the decomposition of protein to form heterocycle compounds in the resulting cake according to in situ FTIR results. The nano γ-Fe2O3 catalysis to cake also can be observed for the activation energy was lower than blank in the range of 40Ë60%. The study demonstrated concept and the effectiveness the reuse/recycle of the Fenton iron sludge for dewatering of SS.

Occupational pneumoconiosis refers to a group of occupational pulmonary diseases,which is mainly characterized by diffuse fibrosis of lung tissue caused by inhalation of different pathogenic productive dust and retention in the lungs during occupational activities for a long period of time. According to the classification and catalogue of occupational diseases in China,it is mainly classified into 12 categories,such as silicosis,coal worker's pneumoconiosis,asbestos lung. At present,it is the most serious and most common occupational disease in China. The pathogenesis of pneumoconiosis is not clear,and there is still no effective therapy. In the past three years,it is found that traditional Chinese medicine is effective in the treatment of pneumoconiosis. Through collection of medical records,the regularity of the prescriptions used in the treatment of pneumoconiosis were analyzed and summarized. According to the traditional Chinese medicine theory,the clinical characteristics of recurrent cough,phlegm and asthma in patients with pneumoconiosis could be included in the categories of cough,wheezing,lung distension. Professor Ma Guiqin believes that the basic pathogenesis of pneumoconiosis is depression of the atmosphere,deficiency of the kidney,internal obstruction of phlegm,and adverse cardinality. According to its pathogenesis,the commonly used prescriptions,namely Shengxian Decoction,Jinshui Liujun Jian,Xiaochaihu Decoction,Sini Powder,Guomin Jian and syndrome differentiation-based modified medicines were expounded. In addition, " throat is the gateway to the lung and stomach",Professor Ma also believes that the prevention of pneumoconiosis should start with the throat,so as to curb the exacerbation or recurrence of the disease. Through clinical observation,if traditional Chinese medicine is properly used,and pathogenesis and syndrome differentiation-based treatment is provided,traditional Chinese medicine can relieve the clinical symptoms,and improve the exercise tolerance and the quality of life of patients with pneumoconiosis.

Chlorophyll content,leaf mass to per area,net photosynthetic rate and bioactive ingredients of Asarum heterotropoides var. mandshuricum,a skiophyte grown in four levels of solar irradiance were measured and analyzed in order to investigate the response of photosynthetic capability to light irradiance and other environmental factors. It suggested that the leaf mass to per area of plant was greatest value of four kinds of light irradiance and decreasing intensity of solar irradiance resulted in the decrease of leaf mass to per area at every phenological stage. At expanding leaf stage,the rate of Chla and Chlb was 3. 11 when A. heterotropoides var. mandshuricum grew in full light irradiance which is similar to the rate of heliophytes,however,the rate of Chla and Chlb was below to 3. 0 when they grew in shading environment. The content of Chla,Chlb and Chl( a+b) was the greatest value of four kinds of light irradiance and decreasing intensity of solar irradiance resulted in its decreasing remarkably( P<0. 05). The rate of Chla and Chlb decreased but the content of Chla,Chlb and Chl( a+b) increased gradually with continued shading. The maximum value of photosynthetically active radiation appeared at 10: 00-12: 00 am in a day. The maximum value of net photosynthetic rate appeared at 8: 30-9: 00 am and the minimum value appeared at 14: 00-14: 30 pm at each phenological stage if plants grew in full sunlight. However,when plants grew in shading,the maximum value of net photosynthetic rate appeared at about 10: 30 am and the minimum value appeared at 12: 20-12: 50 pm at each phenological stage. At expanding leaf stage and flowering stage,the average of net photosynthetic rate of leaves in full sunlight was remarkably higher than those in shading and it decreased greatly with decreasing of irradiance gradually( P < 0. 05). However,at fruiting stage,the average of net photosynthetic rate of leaves in full sunlight was lower than those in 50% and 28% full sunlight but higher than those in 12% full sunlight. All photosynthetic diurnal variation parameters of plants measured in four kinds of different irradiance at three stages were used in correlation analysis. The results suggested that no significant correlation was observed between net photosynthetic rate and photosynthetically active radiation,and significant negative correlation was observed between net photosynthetic rate and environmental temperature as well as vapor pressure deficit expect for 12% full sunlight. Positive correlation was observed between net photosynthestic rate and relative humidity expect for 12% full sunlight. Significant positive correlation was observed between net photosynthetic rate and stomatal conductance in the four light treatments. Only,in 12% full sunlight,the net photosynthetic rate was significantly related to photosynthetically active radiation rather than related to environmental temperature,vapor pressure deficit and relative humidity. In each light treatment,a significant positive correlation was observed between environmental temperature and vapor pressure deficit,relative humidity as well as stomatal conductance. Volatile oil content was 1. 46%,2. 16%,1. 56%,1. 30% respectively. ethanol extracts was 23. 44%,22. 45%,22. 18%,21. 12% respectively. Asarinin content was 0. 281%,0. 291%,0. 279% and 0. 252% respectively. The characteristic components of Asarum volatile oil of plant in different light treatments did not change significantly among different groups.

This study aims to observe the intervention effects of Chinese herbal medicine of supplementing Qi and activating blood circulation on chronic intermittent hypoxia(CIH) composite insulin resistance(IR) mediated atherosclerosis(AS) mice model,and to observe the mechanism of SREBP-1 c signaling molecule.IR Apo E-/-mice model was induced by high-fat diet combined with STZ injection.Then the mice were treated with hypoxic animal incubator for 8 h per day and 8 weeks to establish a CIH+IR-ApoE-/-mouse model.Model mice were randomly and averagely divided into normoxic control group(NC),model group(CIH) and SREBPs inhibitor group(betulin),atorvastatin group(WM),TCM low-dose group(TCM-L),TCM middle-dose group(TCM-M) and TCM high-dose group(TCM-H) group.Chinese herbal medicine of supplementing Qi and activating blood circulation including ginsenosides combined with ligustrazine(TMP) were used as intervention drugs.The study observed the effect of drugs on IR,serum lipid,inflammation,stress,AS and SREBP-1 c related molecules.The results showed that fasting blood glucose in TCM-H group decreased compared with other experimental groups(P<0.05).HDL-C level in betulin group,WM group,TCM-H group was higher than that in CIH group(P<0.05).LDL-C level in TCM-M group,TCM-H group is lower than that in CIH group(P<0.05).The level of CRP in CIH group was higher than that in other groups(P<0.05).The level of SOD in TCM-H group was higher than that in CIH group(P<0.05).NC group and CIH group showed obvious AS aortic plaque,while betulin group,WM group,TCM-H group showed reduction in AS plaque(P<0.05).For descending aorta,AS plaque in CIH group was multiple and large,while less and smaller in WM group and TCM-H(P<0.05).The expression of SREBP-1 c and FAS in aorta and skeletal muscle in TCM-H group was lower than that in CIH group(P<0.05).In aorta,the expression of TNF-α and CD106(VCAM-1) was lower in TCM-H group than that in CIH group(P<0.05).In aorta,skeletal muscle and liver,the level of p-IRS-1 in TCM-H group was significantly higher than that in CIH group(P<0.05).In aorta and liver,the expression of HIF-1α in TCM-H group was lower than that in CIH group(P<0.05).The study demonstrated that combination ginsenosides with TMP could improve IR and serum lipid level and inhibit inflammation and oxidative stress as well as ultimately alleviate AS to some extent.And the mechanism of its interventional effects might be related to the inhibition of CIH-induced upregulation of SREBP-1 c related molecules.

Consistency in quality of traditional Chinese medicine granules is an important factor to ensure reproducible clinical efficacy. In this study rhubarb dispensing granules were utilized to construct an efficacious near-infrared spectroscopy (eNIRS) assay by combining NIRS and biopotency. A NIR method for assaying rhubarb dispensing particles was established, and information on different batches was collected. The diarrhea-inducing biopotency of rhubarb dispensing granules was determined based on a constipation model induced by diphenoxylate in mice. The animal protocol was approved by the Animal Ethic Committee of 302 Hospital of Chinese PLA People's Liberation Army (ID: IACUC-2019-0010). Ten anthraquinones were determined in rhubarb dispensing granules by UPLC. The correlation between NIR and biopotency was analyzed and five characteristic bands that correlated highly with bioactivity were identified, including 4 011-4 390, 4 859-5 461, 7 012-7 493, 10 992-11 312 and 11 871-12 489 cm-1. There were some differences in the main bands of different chemical constituents. In summary, five active bands based on NIRS were identified and found to be able to achieve rapid on-line detection of rhubarb dispensing granule quality. This research model may also provide reference for quality control of other Chinese medicine dispensing granules.
RESUMO
Objective To study the effects of Xihuang pills combined with sodium cantharidinate and vitamin B6 injection in the treatment of tumor-induced fever. Methods A total of 100 patients with tumor-induced fever in our hospital from March 2015 to January 2017 were enrolled in this study. The subjects were divided into the control group (n=50) and the treatment group (n=50) randomly. The control group were treated with aspirin-D L-Lysine injection, and the treatment group were treated with Xihuang pills combined with sodium cantharidinate and vitamin B6 injection. The two groups were treated for 2 periods. The clinical effects of the two groups after treatment were compared. The life quality of the two groups after treatment were compared. The serum TNF-α and IL-1β of the two groups before and after treatment were compared. The adverse reaction rates of the two groups during treatment were compared. Results The total efficacy rate of defervescence of the treatment group was 88.0%(44/50) significantly higher than 56.0%(28/50) of the control group (χ2=12.698, P=0.000). After treatment, the daily life score (1.10 ± 0.18 vs. 2.47 ± 0.21, t=35.025), social communication score (1.21 ± 0.13 vs. 2.53 ± 0.25, t=33.124), mental state score (1.08 ± 0.15 vs. 2.75 ± 0.21,t=45.758), appetite score (1.13 ± 0.16 vs. 2.56 ± 0.19, t=40.708), sleep score (1.22 ± 0.17 vs. 2.71 ± 0.20, t=40.139) of the treatment group were significantly lower than those of the control group (P<0.05). After treatment, the serum TNF-α (1.98 ± 0.07 μg/L vs. 2.86 ± 0.13 μg/L, t=42.144), IL-1β (9.20 ± 1.89 μg/L vs. 13.51 ± 2.36 μg/L, t=10.080) of the treatment group were significantly lower than those of the control group (P<0.05). There was no significantly differences of the adverse reaction rates of the two groups during treatment (χ2=0.211, P=0.646). Conclusions The Xihuang pills combined with sodium cantharidinate and vitamin B6 injection for patients with tumor-induced fever has a good efficacy and low incidence of adverse reactions, can improve the quality of life and reduce the serum levels of TNF-α and IL-1β.
