ABSTRACT
OBJECTIVE: To elucidate the potential feature and mechanism of the caffeic acid 3,4-dihydroxyphenethyl ester (CADPE) molecule, which can prevent colorectal cancer (CRC) in the 1,2-Dimethylhydrazine (DMH)/dextran sodium sulphate (DSS)-induced mouse model. METHODS: Institute of cancer research (ICR) male mice were injected with 20 mg/kg DMH for a week. After that, 2% DSS was administered in the drinking water for another 7 d. The CADPE treatment was given to the DMH/DSS induced male mice at three different periods until their sacrifice. Histopathological examination was used for observing the CRC development at colonic mucosa. Immunohistochemistry (IHC), blood cells smearing and crypt damage scoring methods were used for investigating the anti-inflammation feature of CADPE related to CRC. The reversing targets searching method was applied with artificial intelligence (AI), computer-aided drug designing (CADD) and Ingenuity Pathway Analysis (IPA) techniques for predicting the potential targets and mechanism of CADPE highly related to CRC. RESULTS: The data indicated that CADPE inhibited CRC tumor development in the colitis-associated DMH/DSS induced mouse model after giving the early treatment. CADPE also impeded the acute inflammation by decreasing the infiltration of neutrophils significantly during the initial stage of CRC development. Finally, our data showed that CADPE prevented CRC by blocking active sites of three pivotal protein targets including epidermal growth factor receptor (EGFR), extracellular signal-regulated kinase (ERK) and mammalian target of rapamycin (mTOR) in two major cancer development pathways. CONCLUSIONS: CADPE effectively prevented CRC at early stage of tumor germination in the DMH/DSS mouse model highly likely due to its anti-acute inflammation characteristic and the ability of blocking EGFR, ERK and mTOR activities in two highly related CRC developing pathways.

In this work, a novel triphenylamine-benzofuran derived fluorescent probe, TBF-SS, was developed for detecting hydrogen polysulfide in tea samples and intracellular imaging. TBF-SS showed the practical advantages including high sensitivity (LOD = 0.01 µM), high selectivity, rapid response (within 15 min), and steadiness in various environmental conditions. The detecting system was steady within pH range of 6.0-11.0 and temperature range of 20-55 °C. The probe TBF-SS could guarantee the stable detection of H2Sn for 7 d in storage of either solid or solution. In particular, in the application of various tea samples with different brewing times and testing temperatures, the recovery percentages varied in the range of 95.22 % to 105.0 %. Therefore accurate monitoring of H2Sn could be achieved by using the probe TBF-SS. In addition, TBF-SS could monitor the exogenous level, the ß-lapachone-induced generation and the tea-sample-treated introduction of H2Sn in living MCF-7 cells. This work might inspire the improvement of the serviceability of fluorescent implements.

Panacis Quinquefolii Radix is the dry root of Panax quinquefolium, which is a perennial plant of Araliaceae. The plant has a long growth cycle and serious growth barrier problem, which leads to the use of pesticides. As a result, the pesticide residues in Panacis Quinquefolii Radix are arousing great concern. This paper reviews the research findings on the investigation, detection methods, content analysis and risk assessment of pesticide residues in Panacis Quinquefolii Radix since 1993, and compares the pesticide residue limit standards of different countries and regions. The pesticide residues in Panacis Quinquefolii Radix have been changing from organochlorines with high toxicity to triazines and triazoles with low toxicity. The pesticide residues are generally low, while the pollution of pentachloronitrobenzene and other pesticides still exist. The detection method has evolved from chromatography to chromatography-mass spectrometry. There are no reports of health risks caused by pesticide residues of Panacis Quinquefolii Radix. Pesticide residue is a major factor restricting the sound development of Panacis Quinquefolii Radix industry in China. Therefore, we suggest to improve the registration of pesticides applied to the plant, popularize mature ecological planting mode and supporting technology, and strengthen the research on the risk assessment and limit standard of pesticide residue in Panacis Quinquefolii Radix.

ABSTRACT
Objective:To screen the factors that were conducive to prolonging the effective half-life of 131I, and to provide a basis for selecting more suitable patients for the treatment of hyperthyroidism with lithium carbonate assisted radioactive 131I. Methods:Between July 2017 and March 2019, a total of 61 patients (23 males, 38 females, age: 13-73 (37.7±1.9) years) who received lithium carbonate adjuvant therapy before 131I treatment in the First Affiliated Hospital of Zhengzhou University were collected into this prospective study. Clinical parameters (serum free triiodothyronine (FT 3), serum free thyroxine (FT 4), iodine uptake rate (2 h, 12 h, 24 h) and ratio of iodine uptake rate (2 h/24 h, 4 h/24 h) before and after taking lithium carbonate were compared by using paired t test. The factors which were conducive to prolonging the effective half-life of 131I were analyzed by linear and multiple regression analyses. Results:Compared with the pretreatment results, lithium carbonate treatment significantly improved the 24 h iodine uptake rate ((74.82±2.69)% vs (82.38±2.33)%; t=2.674, P=0.010), decreased the ratio of 4 h/24 h iodine uptake rate ((88.96±2.85)% vs (82.12±2.27)%; t=2.644, P=0.010), prolonged the effective half-life of 131I ((123.03±3.09) vs (130.38±2.49) h; t=2.656, P=0.010), and decreased serum FT 3 ((26.46±1.65) vs (21.31±1.42) pmol/L; t=3.421, P=0.001) and serum FT 4 ((56.59±2.12) vs (49.24±2.19) pmol/L; t=3.289, P=0.002). Linear regression analysis showed that 2 h and 4 h iodine uptake rate, the ratios of 2 h/24 h and 4 h/24 h iodine uptake rate, and effective half-life of 131I before lithium carbonate treatment were related to the effective half-life of 131I after lithium carbonate treatment ( b values: from -0.576 to 0.642, all P<0.05). Multiple linear regression analysis showed that the ratio of 4 h/24 h iodine uptake rate was the main factor affecting the effective half-life of 131I after taking lithium carbonate ( b=0.642, 95% CI: 0.453-0.832, P<0.001). Multiple linear regression equation was y=-49.785+ 0.642 x. Lithium carbonate treatment could prolong the effective half-life of 131I if the ratio of 4 h/24 h iodine uptake exceeded 77.55%. Conclusion:The ratio of 4 h/24 h iodine uptake rate is the main factor affecting the change of the effective half-life of 131I after lithium carbonate treatment, and patients with hyperthyroidism whose ratio of 4 h/24 h iodine uptake rate exceeds 77.55% can effectively prolong the effective half-life of 131I after taking lithium carbonate.
ABSTRACT
Licorice is one of the most commonly used traditional Chinese medicine. In clinic, raw licorice and honey-fried licorice are used in medicines, with the main effects in clearing away heat and detoxifying, moistening lungs and removing phlegm. Honey-fried licorice has effects in nourishing the spleen and stomach and replenishing Qi and pulse. Because traditional Chinese medicine exerts the effects through multiple components and multiple targets, the index components used in the quality evaluation of licorice are often difficult to reflect their real quality. In addition, most of studies for the quality standards have shown that honey-fried licorice are the same as licorice, with a lack of quality evaluation standards that can demonstrate their processing characteristics. The quality of medicine is directly related to its clinical efficacy, so it is necessary to establish a more effective quality control method. Licorice has a beany smell, which is one of the main quality identification characteristics. In this study, by taking advantage of the odor characteristics, a headspace-gas chromatography-ion migration mass spectrometry technology was used to establish a quality evaluation method. A total of 76 volatile components were identified. Through the dynamic principal component analysis, 7 kinds of volatile substances in raw licorice and 13 kinds of volatile substances in honey-fried licorice were statistically obtained, and could be taken as index components for the quality evaluation of raw and honey-fried licorice, respectively. This study could help realize the combination and unification of modern detection and traditional quality evaluation methods, and make a more realistic evaluation for the quality of licorice.

BACKGROUND AND OBJECTIVES: To investigate the clinical outcomes in septic patients receiving parenteral fish oil. METHODS AND STUDY DESIGN: A prospective, non-randomized, observational clinical study was carried out in 112 patients with sepsis from March, 2013 to May, 2015 in the surgical intensive care unit (SICU) of a tertiaryreferral hospital. The patients were put into one of two groups; either the control or the study group. Patients received the standard treatment of sepsis based on guidelines in the control group. In the study group, patients received parenteral nutrition (PN) containing fish oil. The Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, the length of ICU and hospital stay, duration of mechanical ventilation, mortality, and readmission into the ICU were recorded. Tumor necrosis factor (TNF)-α and procalcitonin (PCT) levels were also evaluated. RESULTS: The study group showed a significant reduction for all-cause mortality (20.0% vs 10.0% in study and control groups, p=0.034) and APACHE II score on day 5 (p=0.015), day 7 (p=0.036) and day out of SICU (p=0.045) compared with the control group. The study group tended to show a shortened length of stay in the ICU compared to the control group. However, TNF-α and PCT level, 28 d mortality, the length of hospital stay and the duration of mechanical ventilation did not show statistical differences between the two groups. There were no drug-related adverse effects shown during the study. CONCLUSIONS: PN with fish oil is probably safe and may improve clinical outcome in critical ill patients with sepsis.

ABC efflux proteins are a kind of transporters mediating diversified endogenous and exogenous efflux protein substrates across the plasma membrane by depending on the chemical energy released by ATP hydrolysis. As a vitally important functional membrane, it is widely found in various tissues and organs. The drug changes the expressions and/or functions of the transport proteins, which will affect the disposal process of substrate drugs corresponding to transporters , and finally lead to the pharmacokinetic interactions. The efflux proteins take part in the absorption, distribution, metabolism and excretion of drugs, and mainly consist of P-glycoprotein(P-gp), multidrug resistance associated protein(MRP) and breast cancer resistance protein(BCRP). The induction effect or inhibition effect of drugs on efflux protein plays a greatly significant role in the drug interaction produced by the compatibility of traditional Chinese medicine, which may be one of the important mechanisms of the theory of seven features of compatibility. In this article, the effects of seven features of compatibility on the ABC efflux transporters were reviewed, in order to reveal the roles of efflux protein in the herb-pairs compatibility, and provide new ideas for the mechanism and rationality of herb compatibility.

According to the characteristics of the physiopathologic of children, based on the clinical practice, this article believed that the occurrence of this disease was closely related to the ascending the clear of the spleen, the descending turbidity of the stomach, the dispersion of the lung and the catharsis of the liver. The root of pathogenesis is disturbance in ascending and descending of the functional activities of qi, so it is effective to treat the disease with the theory of qi ascending and descending.
ABSTRACT
The incidence of idiopathic membranous nephropathy (IMN) is increasing year by year, and the clinical research on Chinese medicine treatment of INM is also growing. This study aims to evaluate the efficiency and safety of Yiqi Huoxue method for IMN. Data sources used were from PubMed, EMbase, the Cochrane Library, CBM, CNKI, Wanfang and VIP database. Two researchers independently screened the literature and extracted data. RevMan 5.3 software was used for Meta analysis, and the evidences were graded for the outcomes according to GRADE system by using GRADEprofiler 3.6. Eventually, eleven trials (725 participants) were included in the Meta-analyses. There was statistically significant difference between Yiqi Huoxue method and controls when combining all trials in 24 h UTP [RR=-1.23, 95%CI=(-1.94,-0.53), P=0.000 6] or when combining all trials in ALB [RR=3.56, 95%CI=(1.64, 5.47), P=0.000 3]. Meanwhile, there was statistically significant difference between Yiqi Huoxue method and controls when combining all trials in TC [RR=-0.39, 95%CI=(-0.57, -0.20), P<0.000 1] or when combining all trials in TG [RR=-0.49, 95%CI=(-0.82, -0.15), P=0.004]. However, there was no statistically significant difference between Yiqi Huoxue method and controls when combining all trials in Scr [RR=-3.25, 95%CI=(-9.35, 2.84), P=0.30] or when combining all trials in BUN [RR=-0.81,95%CI=(-2.29, 0.66), P=0.28]. In the statistics, the most frequently used Chinese medicines in clinical application were Astragali Radix, Angelicae Sinensis Radix, Chuanxiong Rhizoma, Codonopsis Radix, Atractylodis Macrocephalae Rhizome and Salvia Miltiorrhiza. The present evidences suggested that Yiqi Huoxue method should be thought highly of in the treatment of IMN, and at the same time, the rational use of traditional Chinese medicine, such as Astragali Radix, Angelicae Sinensis Radix, Chuanxiong Rhizoma also should be paid attention to. However, due to the GRADE evidence grading of the primary outcome measure of 24 h UTP had very low quality, this review can not provide high-quality evidence to prove the clinical efficacy of this method. More well-designed and large-scale multi-center randomized controlled trials should be conducted in the future for verification.
ABSTRACT
Marsdenia tenacissima extract (MTE, trade name: Xiao-Ai-Ping injection) is an extract of a single Chinese plant medicine. It has been used for the treatment of cancer in China for decades, especially for esophageal cancer and other cancers in the digestive tract. In the present study, the potential mechanism for MTE's activity in esophageal cancer was explored. The effects of MTE on the proliferation of human esophageal cancer cells (KYSE150 and Eca-109) were investigated by the MTT assay, the BrdU (bromodeoxyuridine) incorporation immunofluorescence assay, and flow cytometric analysis. MTE inhibited cell proliferation through inducing G0/G1 cell cycle arrest in KYSE150 and Eca-109. Western blot analysis was employed to determine protein levels in the MTE treated cells. Compared with the control cells, the expression levels of the cell cycle regulatory proteins cyclin D1/D2/D3, cyclin E1, CDK2/4/6 (CDK: cyclin dependent kinase), and p-Rb were decreased significantly in the cells treated with MTE at 40 mg·mL(-1). In addition, MTE had an inhibitory effect on the MAPK (mitogen-activated protein kinase) signal transduction pathway, including ERK (extracellular signal-regulated kinase), JNK (c-Jun N-terminal kinase), and p38MAPK. Moreover, MTE showed little additional effects on the regulation of cyclin D1/D3, CDK4/6, and p-Rb when the ERK pathway was already inhibited by the specific ERK inhibitor U0126. In conclusion, these data suggest that MTE inhibits human esophageal cancer cell proliferation through regulation of cell cycle regulatory proteins and the MAPK signaling pathways, which is probably mediated by the inhibition of ERK activation.

Astragali Radix was firstly recorded in the "Shen Nong's Herbal Classic" as a top-grade and commonly used traditional Chinese medicine. Its frequently used slices include raw Astragali Radix and honey-processed products. In current studies, many reports were made on honey-processed Astragali Radix, whereas fewer study reports were made on the cutting process of Astragali Radix. Currently, because Astragali Radix is primarily cut by drug workers according to their operating experience, but with out specific cutting parameters, it is easy to cause the loss or mildew of active ingredients. As a result, the quality of Astragali Radix circulated in the market is not guaranteed, and the quality of their slices and preparations are hard to be controlled, which seriously impact the clinical efficacy. In response, this experiment was performed, in which the optimum cutting process of Astragali Radix was taken as the study objective, the Box-Benhnken central composite design in the response surface analysis was adopted, and the content and appearance character of astragaloside and calycosin-7-glucoside were regarded as the study indicators. Three factors, namely the softening time, the drying temperature and the drying time, were selected to optimize the cutting process of Astragali Radix and obtain the optimum cutting process parameters as follows: the softening time was 3 hours, the drying temperature was 50 degrees C, and the drying time was 4 hours. According to the verification test, the Astragali Radix cutting process is steady and feasible, which has certain significance for normalizing the cutting process of Astragali Radix.
