Correlation between traditional Chinese medicine and reduced risk of readmission in rheumatoid arthritis patients with hypoproteinemia:a retrospective cohort study / 中国中药杂志

This study aimed to explore the correlation between traditional Chinese medicine(TCM) and reduced risk of readmission in patients having rheumatoid arthritis with hypoproteinemia(RA-H). A retrospective cohort study was conducted on 2 437 rheumatoid arthritis patients in the information system database of the First Affiliated Hospital of Anhui University of Chinese Medicine from 2014 to 2021, and 476 of them were found to have hypoproteinemia. The patients were divided into TCM users and non-TCM users by propensity score matching. Exposure was defined as the use of oral Chinese patent medicine or herbal decoction for ≥1 month. Cox regression analysis was performed to explore the risk factors of clinical indicators of rheumatoid arthritis. Additionally, the use of TCM during hospitalization was analyzed, and analysis of association rules was conducted to investigate the correlation between TCM, improvement of indicators and readmission of patients. Kaplan-Meier survival curve was plotted to compare the readmission rate of TCM users and non-TCM users. It was found the readmission rate of RA-H patients was significantly higher than that of RA patients. By propensity score matching, 232 RA-H patients were divided into TCM group(116 cases) and non-TCM group(116 cases). Compared with the conditions in the non-TCM group, the readmission rate of the TCM group was lowered(P<0.01), and the readmission rate of middle-aged and elderly patients was higher than that of young patients(P<0.01). Old age was a risk factor for readmission of RA-H patients, while TCM, albumin(ALB) and total protein(TP) were the protective factors. During hospitalization, the TCMs used for RA-H patients were mainly divided into types of activating blood and resolving stasis, relaxing sinew and dredging collaterals, clearing heat and detoxifying, and invigorating spleen and resolving dampness. The improvement of rheumatoid factor(RF), immunoglobulin G(IgG), erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) and ALB was closely related to TCM. On the basis of western medicine treatment, the application of TCM could reduce the readmission rate of RA-H patients, and longer use of TCM indicated lower readmission rate.

Neuroprotection of Chikusetsu saponin V on transient focal cerebral ischemia/reperfusion and the underlying mechanism.

BACKGROUND: Oxidative stress and frequently unwanted alterations in mitochondrial structure and function are key aspects of the pathological cascade in transient focal cerebral ischemia. Chikusetsu saponin V (CHS V), a major component of saponins from Panax japonicas, can attenuate H2O2-induced oxidative stress in SH-SY5Y cells. PURPOSE: The aim of the present study was to investigate the neuroprotective effects and the possible underlying mechanism of CHS V on transient focal cerebral ischemia/reperfusion. METHODS: Mice with middle cerebral artery occlusion (MCAO) and cultured cortical neurons exposed to oxygen glucose deprivation (OGD) were used as in vivo and in vitro models of cerebral ischemia, respectively. The neurobehavioral scores, infarction volumes, H&E staining and some antioxidant levels in the brain were evaluated. The occurrence of neuronal death was estimated. Total and mitochondrial reactive oxygen species (ROS) levels, as well as mitochondrial potential were measured using flow cytometry analysis. Mitochondrial structure and respiratory activity were also examined. Protein levels were investigated by western blotting and immunohistochemistry. RESULTS: CHS V effectively attenuated cerebral ischemia/reperfusion (CI/R) injury, including improving neurological deficits, shrinking infarct volume and reducing the number of apoptotic cells. Furthermore, CHS V treatment remarkably increased antioxidant levels and reduced ROS levels and mitochondrial damage by enhancing the expression and deacetylation of peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) by activating AMPK and SIRT-1, respectively. CONCLUSION: Our data demonstrated that CHS V prevented CI/R injury by suppressing oxidative stress and mitochondrial damage through the modulation of PGC-1α with AMPK and SIRT-1.

Cost-effectiveness analysis of ramucirumab treatment for patients with hepatocellular carcinoma who progressed on sorafenib with α-fetoprotein concentrations of at least 400 ng/ml.

Objective: This study aimed to compare the cost-effectiveness of ramucirumab versus placebo for patients with hepatocellular carcinoma who progressed on sorafenib with α-fetoprotein concentrations (AFP) of at least 400 ng/ml in the United States.Methods: A Markov model was constructed to assess the cost-effectiveness of ramucirumab. Health outcomes were measured as quality-adjusted life years (QALYs). With TreeAge software, the disease process was modeled as three health states: progression-free survival (PFS), progressive disease (PD), and death. Costs were extracted from the REACH-2 trial, and utility was derived from published literature. Incremental cost-effectiveness ratios (ICERs) were calculated to compare ramucirumab with placebo. Probabilistic sensitivity analyses were developed to examine the robustness of the results.Results: In the base case analysis, ramucirumab therapy had a cost of $55,508.41 and generated 0.54 QALYs, while placebo therapy had a cost of $761.09 and generated 0.47 QALYs, leading to an additional $54,747.32 in costs and 0.07 QALYs. The ICER was $782,104.57 per QALY, which was much higher than the willingness-to-pay threshold of $100,000 per QALY. According to sensitivity analyses, the utility of PD in the two groups was the dominant parameter influencing the ICER.Conclusion: Although ramucirumab was associated with prolonged survival for patients with advanced hepatocellular carcinoma who progressed on sorafenib treatment with an AFP of at least 400 ng/ml, it is not a cost-effective treatment from a United States payer perspective.

Analysis on low transfer rate of active constituents by water extracting from Chinese materia medica / 中草药

To point out the current problems on the water extraction process in the preparation of patent medicine or single medicine recorded in Chinese Pharmacopoeia 2010, and to provide the references for the next Chinese Pharmacopoeia and the water extraction technology of traditional Chinese patent medicine (CPM) industry. According to Chinese Pharmacopoeia 2010 and literature at home and abroad, the four basic stages of extraction were analyzed and the problems on the low transfer rate of active constituents by water extraction were discussed. In the four stages of water extraction process, any stage that was limited led to the low transfer rate of active constituents or even influenced the drug's efficacy directly. Not only the poor permeability of water, but also the high oil and macromolecular components in Chinese herbs could limit the infiltration with water as solvent. In desorption and dissolution stages, the poor solubility of nonpolar and medium polarity components with a low affinity for water was difficult to dissolve completely. In diffusion stage, the active constituents in Chinese materia medica were difficult to penetrate the cellular barrier and spread to the water due to the larger molecular weight. In substitution stage, coexisting macromolecular substances affect the other mass exchanges on both sides of cell biological membrane in the process of material mutual exchanges. It is the common problem that water extraction ratio of CPM is low. It is also the urgent problem of Chinese Pharmacopoeia to be solved, or it will definitely hinder the development of industrial CPM. Insiders should pay more attention to this problem and take new ideas to solve it.

Besides, a blank control group was set up. Starting from the 2nd day of modeling, GLP, at the dose of 1.02 g/kg was given to GLP group and GLP + CTX group by gastrogavage once a day for 12 successive days; CTX at the dose of 100 mg/kg was administered via peritoneal injection to the CTX group and the GLP + CTX group on the 1st day and the 6th day of the experimental course; but to the model group and the blank group, only equal volume of distilled water was given. All mice were sacrificed on the 14th day, the ileum at 1 cm upper to cecum was taken, through 4% paraform fixation and paraffin section, it was used for immunohistochemical detecting expressions of immunoglobulin A (IgA), tumor necrosis factor-alpha (TNF-alpha), interleukin-2 (IL-2) and interleukin-10 (IL-10) in ileum. Besides, the lymphocyte subsets in the intraepithelial lymphocyte (IEL), lamina propria lymphocytes (LPL), and Peyer's patch lymphocytes (PPL) were analyzed by immune fluorescence technique and flow cytometry.</p><p><b>RESULTS</b>Compared with the blank control group, the phenotype of lymphocytes and the expression of cytokines in ileum in the model group changed significantly; and the phenotype was variant in different regions. Compared with the model group, both indexes were adjusted in the GLP, CTX and GLP + CTX group to different degrees.</p><p><b>CONCLUSION</b>The adjustment of GLP on intestinal mucosal immune is probably another path for its anti-tumor action.</p>

Anti-cancer activity of Zuojinwan in vivo and influence to tumor markers in mice transplanted with sarcoma 180 / 中国中药杂志

<p><b>OBJECTIVE</b>To study the anticancer action of Zuojinwan in mice transplanted with sarcoma 180 in vivo, and detect the activities of five kinds of tumor markers (TM) including acid phosphotase (ACP), alkaline phosphotase (AKP), creatine kinase (CK), aldolase (ALD) and lactate dehydrogenase (LDH) in serum compared with Coptis chinensis and Evodia rutaecarpa.</p><p><b>METHOD</b>The transplanted S180 tumor mice model was established, and the mice were divided randomly five groups. The extract of Zuojinwan (850.8 mg kg(-1)), C. chinensis (729.2 mg kg(-1)) and E. rutaecarpa (121.6 mg kg(-1)) were administrated, respectively for 10 d. Then, the changes of body weight, spleen index of mice, the inhibition rates of tumor, and the increase of life span (ILS) were all tested. In addition, the activities of ACP, AKP, CK, ALD and LDH on different test groups were also determined.</p><p><b>RESULT</b>Zuojinwan could inhibit the S180 tumor growth significantly with the inhibition rate of 50.54% and the ILS of mice reached to 64.91%. Meanwhile, the activities of ACP (126.72 +/- 11.16) U 100 mL(-1) and AKP (67.27 +/- 13.49) U 100 mL(-1) were increased, and the activities of CK (20.65 +/- 4.28) U mL(-1), ALD (319.13 +/- 53.87) U L(-1) and LDH (1,029.04 +/- 468.56) U L(-1) were decreased significantly by Zuojinwan treated group compared with C. chinensis and E. rutaecarpa treated groups (P<0.01).</p><p><b>CONCLUSION</b>In the prescription of Zuojinwan, the enhancement of compatibility of anticancer activity was observed by the interaction of C. chinensis and E. rutaecarpa. The mechanism might be in according with to influence the activities of the five kinds of tumor markers (TM) in mice serum.</p>
