RESUMEN

Prevention is better than cure. A milestone of the anthropocene is the emergence of a series of epidemics and pandemics often characterized by the transmission of a pathogen from animals to human in the past two decades. In particular, the coronavirus disease 2019 (COVID-19) has made a profound impact on emergency responding and policy-making in a public health crisis. Classical solutions for controlling the virus, such as travel restrictions, lockdowns, repurposed drugs and vaccines, are socially unpopular and medically limited by the fast mutation and adaptation of the virus. This is exacerbated by microbial resistance to therapeutic drugs and the slowness of vaccine development. In other words, microbial pathogens are somehow 'smarter' and faster than us, thus calling for more intelligent cures to combat future pandemics. Here, we compare therapeutics for COVID-19 such as synthetic drugs, vaccines, antibodies and phages. We present the strength and limitations of antibiotic and antiviral drugs, vaccines, and antibody-based therapeutics. We describe smarter, cheaper and preventive cures such as bacteriophages, food medicine using probiotics and prebiotics, sports, healthy diet, music, yoga, Tai Chi, dance, reading, knitting, cooking and outdoor activities. Some of these preventive cures have been intuitively developed since thousands of years ago, as illustrated by the fascinating similarity of the Chinese characters for 'music' and 'herbal medicine.'

RESUMEN

Non-small cell lung cancer (NSCLC) is a serious threat to people's health. This study aims to determine the possible effect of Gujin Xiaoliu Tang (GJXLT) on NSCLC, which is an empirical formula from Professor Dai-Han Zhou. In this study, chromatographic fingerprinting of GJXLT and A549 cell model in vitro and in vivo was established. We cultured A549 cells in vitro and found that GJXLT inhibited A549 cell growth and induced apoptosis. Compared with the control group, the expression of p-STAT3 and VEGF proteins in the GJXLT groups was decreased. Similar findings were also observed in vivo. First, GJXLT inhibited the growth of transplanted tumor and did not reduce the weight of the tumor-bearing mice in comparison with that of the control group. Then, the Ki-67 expression of transplanted tumor in the GJXLT groups was decreased. In addition, the apoptosis rate of transplanted tumor in the GJXLT groups was increased. Overall, our data showed that GJXLT inhibited A549 cell proliferation and induced apoptosis in vivo and in vitro. Furthermore, GJXLT inhibited the growth of lung cancer xenograft in nude mice model with no obvious side effects. The anti-tumor effect of GJXLT might also be related to the inhibition of p-STATS and VEGF expression in the JAK2/STAT3 pathway. Our results demonstrated the potential of GJXLT as a novel treatment for NSCLC.

RESUMEN

OBJECTIVES: To investigate the role of prolyl 4-hydroxylase beta polypeptide (P4HB) expressed in lung carcinoma and the intervention effect of Yiqi Chutan Formula (, YQCTF). METHODS: Lung carcinoma model was established by subcutaneously inoculating LEWIS lung carcinoma cells in C57BL/6J mice. The differential expression of P4HB protein between the YQCTF (3.0 g/kg, gavage, once daily, 21 days) group and the control group was acquired by a 2 fluorescence difference gel electrophoresis (2D-DIGE), verified by Western blotting and identified by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF/TOF-MS). The expression of P4HB and P4HB mRNA in cultured A549 cells from cisplatin (DDP) 1.5 µg/mL group and 15% serum combined with DDP 1.5 µg/mL group were detected by cellular immunohistochemistry and reverse transcription-polymerase chain reaction, respectively. RESULTS: The proteomics research discovered that one-third of differential proteins including P4HB were decreased in the YQCTF group (P<0.01). Clinical pathology and tissue microarray studies showed that P4HB expression in lung cancer tissue was stronger than adjacent tissues and normal lung epithelial (P<0.01). In the YQCTF and DDP combined groups, the expression of P4HB and P4HB mRNA in A549 cell were decreased significantly (P<0.01). CONCLUSION: YQCTF could inhibit the LEWIS lung carcinoma's growth, decrease the expression of P4HB in LEWIS lung carcinoma and A549 cells. YQCTF might take effect through regulating P4HB in endoplasmic reticulum to inhibit the incidence and growth process of lung carcinoma.

RESUMEN

A magnetic solid-phase extraction method using ionic liquid (IL)-micelle-functionalized mesoporous Fe3O4 microspheres (MFMs) was proposed for the preconcentration of anthraquinones in dietary supplements. The analytes were then determined by ultraperformance liquid chromatography combined with an ultraviolet detector. The extraction parameters, such as the choice of ILs, the concentrations of ILs and MFMs, the pH of diluent, and the concentration of acetic acid in the eluent, were presented. Under the optimized conditions, the limits of detection and limits of quantitation were 0.4-2.8 ng mL(-1) and 1.4-9.4 ng mL(-1), respectively. The accuracy of the proposed method was investigated by recovery in herb and granules of Radix et Rhizoma Rhei, yielding values between 89.25% and 96.48%. The use of the proposed method in the sample pretreatment of complex dietary supplements is feasible due to the high surface area and excellent adsorption capacity of MFMs after modification with IL.

RESUMEN

A rapid zwitterionic microemulsion electrokinetic chromatography (ZI-MEEKC) approach coupled with light-emitting-diode-induced fluorescence (LED-IF, 480nm) detection was proposed for the analysis of flavonoids. In the optimization process, we systematically investigated the separation conditions, including the surfactants, cosurfactants, pH, buffers and fluorescence parameters. It was found that the baseline separation of the seven flavonoids was obtained in less than 5min with a running buffer consisting of 92.9% (v/v) 5mM sodium borate, 0.6% (w/v) ZI surfactant, 0.5% (w/v) ethyl acetate and 6.0% (w/v) 1-butanol. High sensitivity was obtained by the application of LED-IF detection. The limits of detection for seven flavonoids were in the range of 3.30×10(-8) to 2.15×10(-6)molL(-1) without derivatization. Ultimately, the detection method was successfully applied to the analysis of flavonoids in hawthorn plant and food products with satisfactory results.

RESUMEN

An ionic liquid (IL)-based one-step micellar extraction procedure was developed for the extraction of multiclass polar analytes (protocatechuic acid, chlorogenic acid, epicatechin, hyperoside, isoquercitrin, quercetin) from hawthorn fruits and their determination using ultrahigh-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UHPLC-Q-TOF/MS). Compared to conventional organic solvent extractions, this newly proposed method was much easier, more sensitive, environmentally friendly, and effective as well. Several important parameters influencing the micellar extraction efficiency are discussed, such as selection of ILs, surfactant concentration, and extraction time. Under the optimal conditions, good linearity was achieved for each analyte with correlation coefficients (r(2)) ranging from 0.9934 to 0.9999, and the recovery values ranged from 89.3 to 106% with relative standard deviations lower than 5.5%. Results suggest that the IL-based one-step micellar extraction could be an alternative and promising means in future food analysis.

RESUMEN

OBJECTIVE: To critically evaluate the currently available randomized clinical trials regarding the effectiveness of acupuncture in palliative care for cancer patients, hence, to provide sufficient evidences for the widespread use of acupuncture in cancer treatment. METHODS: Two independent reviewers extracted data from all of the randomized clinical trials (RCTs) that assessed the efficacy of acupuncture in palliative care for cancer patients. Seven databases were searched from their respective inception to December 2010. All eligible trials identified were evaluated by two independent reviewers using the Jadad scale, and data from the articles were validated and extracted. RESULTS: In total, 33 RCTs met the inclusion criteria. The effects of acupuncture on different cancer-related aspects were shown, including chemotherapy or radiotherapy-induced side effects (13/33, 39.4%), cancer pain (6/33, 18.2%), post-operative urinary retention (4/33, 12.1%), quality of life (2/33, 6.1%), vasomotor syndrome (2/33, 6.1%), post-operative gastrointestinal dysfunction (2/33, 6.1%), prevention of prolonged postoperative ileus (2/33, 6.1%), joint symptoms (1/33, 3.0%), and immunomodulation (1/33, 3.0%). CONCLUSIONS: The result of our systematic review suggested that the effectiveness of acupuncture in palliative care for cancer patients is promising, especially in reducing chemotherapy or radiotherapyinduced side effects and cancer pain. Acupuncture may be an appropriate adjunctive treatment for palliative care.

RESUMEN

A novel additive of multi-walled carbon nanotubes (MWNTs) dispersed with cationic surfactants or mixed cationic/anionic surfactants was used for MEEKC separation of eight phenolic compounds, four glycosides, and one phenanthraquinone. In this context, several parameters affecting MEEKC separation were studied, including the dispersion agents of MWNTs, MWNTs content, oil type, SDS concentration, and the type and concentration of cosurfactant. Compared with conventional MEEKC, the addition of all types of MWNTs dispersions using single or mixed cationic surfactant solutions in running buffers was especially useful for improving the separation of solutes tested, as they influenced the partitioning between the oil droplets and aqueous phase due to the exceptional electrical properties and large surface areas of MWNTs. Use of cationic surfactant-coated MWNTs (6.4 µg/mL) as the additive in a microemulsion buffer (0.5% octanol, 2.8% SDS, 5.8% isopropanol, and 5 mM borate buffer) yielded complete resolution of 13 analytes. The proposed method has been successfully applied for the detection and quantification of the studied compounds in a complex matrix sample (Compound Xueshuantong capsule).

RESUMEN

OBJECTIVES: Bidens bipinnata L. is well known as a traditional antipyretic, anti-inflammatory and anti-rheumatic medicine in China. This study was designed to evaluate the role of total extracted flavonoids from B. bipinnata (TFB) in inhibiting the production of inflammatory cytokines. METHODS: Human umbilical vein endothelial cells (HUVEC) were used to examine the effect of TFB on the production of inflammatory cytokines. The supernatant interleukin (IL)-8, tumour necrosis factor (TNF)-α and nitric oxide (NO) levels of HUVEC were measured with ELISA methods. Nuclear factor-kappaB (NF-κB) and fractalkine expression was evaluated by RT-PCR and Western blot methods, respectively. KEY FINDINGS: We observed that IL-8, TNF-α and NO release of HUVEC incubated with sera from active Henoch-Schönlein purpura (HSP) was significantly increased. TFB intervention may significantly suppressed the supernatant IL-8, TNF-α and NO levels of HUVEC. Similarly, TFB obviously suppressed the NF-κB and fractalkine mRNA and protein expression. CONCLUSIONS: These results suggested that TFB may be useful for improving microvascular inflammation in HSP patients.

RESUMEN

OBJECTIVE: To study the apoptosis inducing effects of Hechanpian (HCP) on human lung adenocarcinoma A549 cells. METHODS: HCP containing rat serum was prepared and applied on A549 cells. The cell growth inhibition rate was tested by MTT assay; the effect of HCP on cell apoptosis was observed with Propidium iodide (PI) staining and flow cytometry analysis; the mRNA expression of epidermal growth factor receptor (EGFR) was detected through RT-PCR. RESULTS: The growth of A549 cells was obviously inhibited after being treated by HCP containing serum, and the cells presented an apoptotic change. The cell apoptosis rate after treated by serum containing 10% and 20% HCP was 20.5% and 33.2%, respectively, significantly higher than that in the control (6.1% in cells didn't treated with HCP, P < 0.05). Compared with control, EGFR mRNA expression in HCP treated cells was significantly lower (P < 0.05). CONCLUSION: HCP has apoptosis inducing effect on A549 cell, and its molecular mechanism is probably correlated with the inhibition of EGFR gene transcription.

RESUMEN

Proteomics plays important roles in Chinese medicine research at post-genomics era. Its research idea and methods are beneficial for elucidating some elemental features of Chinese medicine. At present, Chinese medicine proteomic studies are mainly focusing on the syndromatology and medical herbal pharmacology. However, there are still some problems, the most important matter was that most of the results were merely the superficial delineations. Further research should put emphasize on the unremitting and penetrating study of proteomics, molecular biology and bioinformatics integrally for illuminating Chinese medicine theory deeply to promote the modernization of Chinese medicine research.

RESUMEN

OBJECTIVE: To observe the effect of traditional Chinese medicine (TCM) in improving quality of life of patients with non-small cell lung cancer (NSCLC) in III or IV stage, for establishing TCM therapeutic regimen on late NSCLC. METHODS: A total of 294 patients in 6 hospitals were randomly assigned into three groups, 99 in the TCM group treated with TCM according to disease and syndrome differentiation, 92 treated with chemotherapy in the western group and 103 treated with combined therapy of TCM and chemotherapy in the integrative group. Six items, including physical status, social/family status, intercourse with physicians, emotional status, functional status and additional concerning status, were investigated and analyzed by using Functional Assessment of Cancer Therapy-lung (FACT-L). RESULTS: The scores of social/family status and intercourse with physicians were insignificantly different in all three groups before and after treatment (P > 0.05). The improvement of physical status in the TCM group, and that of emotional status, functional status and additional concerned status in the integrative medicine group were superior to those in the other groups (P< 0.05). CONCLUSION: TCM has certain antagonistic effect on the adverse reaction of chemotherapy, and it can improve the quality of life of patients to certain extent.

RESUMEN

BACKGROUND & OBJECTIVE: Chemotherapy is a treatment for stage III-IV non-small cell lung cancer (NSCLC), but the efficacy is not ideal. Traditional Chinese medicine (TCM) has certain effect on NSCLC. This study was to investigate various factors that affect the prognosis of advanced NSCLC, and evaluate the role of TCM in enlonging survival time of patients with stage III-IV NSCLC. METHODS: The NSCLC patients who meet the inclusive criteria were randomized into TCM group, combination (TCM plus NP regimen) group, and chemotherapy group, and received relevant treatments. The median survival time (MST) was calculated by Kaplan-Meier method. The prognosis of the patients was analyzed by COX regression method. RESULTS: A total of 294 stage III-IV NSCLC patients were enrolled, of which 99 were in TCM group, 103 in combination group, 92 in chemotherapy group. The MST were 292 days in TCM group, 355 days in combination group, and 236 days in chemotherapy group; the cumulative survival rates were 45.38%, 48.86%, and 42.17%, respectively (P>0.05). Cox regression analysis indicated that therapy, gender, disease course, erythrocyte sedimentation, KPS score, tumor size, and patient's weight were independent prognostic factors of stage III-IV NSCLC. CONCLUSION: Compare with chemotherapy alone, TCM combined with chemotherapy may prolong the survival time of stage III-IV NSCLC patients.

RESUMEN

OBJECTIVE: To observe the effect of intervention therapy with Shentao Ruangan pill (SRP) and hydroxycamptothecine (HCPT) in treating 85 patients with middle-advanced large hepatocarcinoma, and to analyze the factors that could affect the prognosis. METHODS: Eighty-five patients were randomly divided into the treated group (n = 52) and the control group (n = 33). The treated group was treated by oral taking of SRP combined with local perfusion of HCPT through hepatic artery catheterization, while to the control group, the conventional therapy, transcatheter arterial chemoembolization (TACE) was conducted for control. The clinical efficacy of treatment in the two groups was evaluated by the change of tumor size, the factors related with prognosis were analyzed using Cox proportional hazards model and the analysis of survival conducted by Kaplan-Meier method. RESULTS: (1) The tumor size reducing rate in the treated group was 19.2% and the tumor size stabilizing rate was 82.7%, while those in the control group was 21.2% and 81.8% respectively, comparison of the criteria between the two groups showed insignificant difference (P > 0.05); (2) The median survival time, 0.5- year, 1- year and 2- year survival rate in the treated group was 326 days, 80.95%, 41.39% and 12.42% respectively, those in the control group was 262 days, 64.29%, 25.00% and 8.33% respectively, comparison between the two groups showed significant difference (P < 0.05); (3) Among the 3 TCM types in patients, the survival time and rates in patients of Gan-excess with Pi-deficiency type was similar to those in patients of Gan-heat with blood stasis type showing insignificant difference (P > 0.05), but as compared with those in patients of Gan-Shen Yin-deficiency type, the difference was significant (P < 0.05) ; (4) Beneficial factor to the prognosis were therapeutic method, that used in the treated group was superior to that used in the control group. The risk factors to the prognosis were TCM type, clinical stage and liver function. Patients of Gan-excess with Pi-deficiency type had the optimal prognosis, those of Gan-heat with blood stasis type the next and of Gan-Shen Yin-deficiency the worst. The later the clinical stage and the worse the Child-Pugh grade of liver function was, the worse the prognosis would be. CONCLUSION: (1) SRP combined with HCPT intervention treatment is superior to the simple TACE treatment in elevating patients' survival rate and time; (2) There are some relations between TCM types and prognosis; (3) Local Chinese drug therapy combined with systemic therapy could be one of the effective measures of non-operational therapy in treating large hepatocarcinoma.
