Effects of Compound Danshen Dripping Pills on Ventricular Remodeling and Cardiac Function after Acute Anterior Wall ST-Segment Elevation Myocardial Infarction (CODE-AAMI): Protocol for a Randomized Placebo-Controlled Trial / 中国结合医学杂志

BACKGROUND@#Ventricular remodeling after acute anterior wall ST-segment elevation myocardial infarction (AAMI) is an important factor in occurrence of heart failure which additionally results in poor prognosis. Therefore, the treatment of ventricular remodeling needs to be further optimized. Compound Danshen Dripping Pills (CDDP), a traditional Chinese medicine, exerts a protective effect on microcirculatory disturbance caused by ischemia-reperfusion injury and attenuates ventricular remodeling after myocardial infarction.@*OBJECTIVE@#This study is designed to evaluate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function after AAMI on a larger scale.@*METHODS@#This study is a multi-center, randomized, double-blind, placebo-controlled, parallel-group clinical trial. The total of 268 patients with AAMI after primary percutaneous coronary intervention (pPCI) will be randomly assigned 1:1 to the CDDP group (n=134) and control group (n=134) with a follow-up of 48 weeks. Both groups will be treated with standard therapy of ST-segment elevation myocardial infarction (STEMI), with the CDDP group administrating 20 tablets of CDDP before pPCI and 10 tablets 3 times daily after pPCI, and the control group treated with a placebo simultaneously. The primary endpoint is 48-week echocardiographic outcomes including left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume index (LVEDVI), and left ventricular end-systolic volume index (LVESVI). The secondary endpoint includes the change in N terminal pro-B-type natriuretic peptide (NT-proBNP) level, arrhythmias, and cardiovascular events (death, cardiac arrest, or cardiopulmonary resuscitation, rehospitalization due to heart failure or angina pectoris, deterioration of cardiac function, and stroke). Investigators and patients are both blinded to the allocated treatment.@*DISCUSSION@#This prospective study will investigate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function in patients undergoing pPCI for a first AAMI. Patients in the CDDP group will be compared with those in the control group. If certified to be effective, CDDP treatment in AAMI will probably be advised on a larger scale.

Objective:To study the clinical application of jejunal feeding tube (J-tube) for early enteral nutrition after surgical treatment of upper digestive tract malformation in newborns.Methods:From January 2019 to December 2021, newborns with upper digestive tract malformation received stage Ⅰ small bowel resection and anastomosis in our hospital were enrolled in this prospective randomized controlled study. According to different types of postoperative nutritional support, these patients were randomly assigned into J-tube group and control group using block randomization method. The J-tube group were given enteral nutrition vis J-tube within 48-72 h after surgery and the control group were given oral feeding after the recovery of gastrointestinal function. Calories and proteins intake, growth indicators, duration of hospital stay and parenteral nutrition, time needed for full oral feeding and complications were compared between the two groups.Results:A total of 24 patients were in J-tube group and 28 in controlled group. No significant differences existed on the general status between the two groups ( P>0.05). The average daily intake of calories and proteins in j-tube group in the first week after surgery were significantly higher than control group [(108.7±8.3) kcal/(kg·d) vs. (97.9±7.0) kcal/(kg·d), (3.4±0.3) g/(kg·d) vs. (3.1±0.2) g/(kg·d)] ( P<0.05). No significant differences existed in the average daily intake of calories and proteins during the second postoperative week between the two groups ( P>0.05). Compared with control group,J-tube group showed increased growth velocity in head circumference and weight over time ( P<0.05), while the trend over time in length growth was not significant ( P>0.05). No significant differences existed in the duration of hospital stay and parenteral nutrition, time needed for full oral feeding and complications between the two groups ( P>0.05). Conclusions:Enteral nutrition via J-tube 48-72 h after surgery is safe and feasible in the postoperative nutritional management of newborns with upper digestive tract malformation. This strategy may promote physical growth after surgery without increasing the incidences of complications.

Qilan preparation inhibits proliferation and induces apoptosis by down-regulating microRNA-21 in human Tca8113 tongue squamous cell carcinoma cells.

OBJECTIVE: The aim of this study was to examine the antitumor effects of Qilan preparation on oral squamous cell carcinoma (OSCC) and to investigate its underlying mechanisms of action. METHODS: Cell proliferation, cell cycle distribution and apoptosis were examined using cell counting kit-8 (CCK8) and flow cytometry (FCM). The expression of PTEN and PDCD4 were determined by western blot. Changes in miR-21 levels were quantified using TaqMan stem-loop real-time PCR. After miR-21 was transiently transfected into Tca8113 cells using Lipofectamine®3000, cell proliferation, apoptosis and miR-21 and PDCD4 expression levels were measured. RESULTS: Qilan preparation inhibited Tca8113 cell growth in a dose- and time-dependent manner by inducing apoptosis and cell cycle arrest in S-phase, decreasing miR-21 levels and increasing PTEN and PDCD4 expression. MiR-21 overexpression reversed the Qilan preparation-induced suppression of cell proliferation and induction of apoptosis while also blocking the increase in PDCD4. CONCLUSIONS: Our study revealed, for the first time, the ability of Qilan preparation to suppress TSCC cell growth and elucidated that Qilan preparation elicits its anti-cancer actions either the miR-21/PDCD4 or PTEN pathway.

The Efficacy and Safety of Chinese Herbal Medicine in the Treatment of Knee Osteoarthritis: An Updated Systematic Review and Meta-Analysis of 56 Randomized Controlled Trials.

OBJECTIVE: This systematic review and meta-analysis were performed to investigate the efficacy and safety of Chinese herbal medicine (CHM) in the treatment of knee osteoarthritis (KOA). METHODS: An electronic search was conducted in eight databases (PubMed, EMBASE, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese VIP Database, and Wanfang Database) from inception until December 2019. The risk of bias assessment of the included RCTs was evaluated by Cochrane collaboration's tool. The inclusion criteria were RCTs that investigated the efficacy and safety of CHM in the treatment of KOA, with no restrictions on publication status or language. The exclusion criteria included nonrandomized or quasi-RCTs, no clear KOA diagnostic approach, combined Chinese medicinal herbs with other traditional Chinese medicine treatment modalities, and published using repeated data and missing data. We computed the relative risk (RR) and the standard mean difference (SMD) for dichotomous outcomes and continuous outcomes, respectively. When heterogeneity was detected or there was significant statistical heterogeneity (P < 0.05 or I 2 > 50%), a random-effects model was employed, followed by further subgroup analysis and metaregression estimations to ascertain the origins of heterogeneity. Otherwise, we used a fixed-effects model (P ≥ 0.05 or I 2 ≤ 50%). The primary outcome measures were visual analog score (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lysholm score, and Lequesne index. Secondary outcome measures were the total clinical effective rate and adverse events. The meta-analysis was performed using the Stata 14.0 software. RESULTS: A total of 56 RCTs comprising 5350 patients met the inclusion criteria. This meta-analysis showed that application of CHM as adjuvant therapy or monotherapy for KOA can significantly decrease VAS, WOMAC, and the Lequesne index and improve the Lysholm score as well as the total effective rate. In addition, this treatment has fewer adverse effects, suggesting that CHM is generally safe and well tolerated among patients with KOA. CONCLUSION: Our study offers supportive evidence that CHM, either adjuvant therapy or monotherapy, reduces the VAS, WOMAC, and Lequesne index and improves the Lysholm score and overall effective rate in patients with KOA. Additionally, CHM was well tolerated and safe in KOA patients. We found frequently used CHMs that might contribute to the formulation of a herbal formula that could be considered for further clinical use. However, given the heterogeneity and limited sample size in this study, larger multicenter and high-quality RCTs are needed to validate the benefits of CHM in the treatment of KOA.

Molecular Mechanism of Resveratrol Against NAFLD Based on Network Pharmacology / 中国实验方剂学杂志

ObjectiveTo predict the molecular mechanism of resveratrol against non-alcoholic fatty liver disease （NAFLD） based on network pharmacology and molecular docking and verify the results on the liver cell model induced by PM2.5 exposure. MethodThe targets of resveratrol were screened out from Traditional Chinese Medicine System Pharmacology Database and Analysis Platform （TCMSP）， PubChem， DrugBank， and SwissTargetPrediction， and the potential targets of NAFLD were retrieved from Comparative Toxicogenomics Database （CTD）， DisGeNET， GeneCards， and Online Mendelian Inheritance in Man （OMIM）. Then the common targets were obtained. STRING 11.5 was used to construct the protein-protein interaction （PPI） network of the common targets. Cytoscape 3.8.2 was used to plot the “target-pathway” network， and the core modules and key targets were selected. Metascape was adopted for Gene Ontology （GO） and Kyoto encyclopedia of genes and genomes （KEGG） enrichment analyses of common targets. SYBYL-X 2.0 was used for molecular docking of resveratrol to key targets. Finally，cell apoptosis and the expression of apoptosis-related proteins were detected by flow cytometry and Western blot in the PM2.5-exposed human liver cell line （HepG2）. ResultA total of 115 common targets of resveratrol and NAFLD were obtained. The key targets included tumor necrosis factor （TNF）， B-cell lymphoma-2 （Bcl-2）， and cysteinyl aspartate-specific protease-3（Caspase-3）. As revealed by KEGG enrichment analysis， 174 signaling pathways， represented by the apoptosis and TNF signaling pathways， were obtained. Molecular docking results showed that resveratrol had strong binding activities to Bcl-2 and Caspase-3. Furthermore，the results of flow cytometry and Western blot demonstrated that resveratrol inhibited cell apoptosis of PM2.5-exposed HepG2 cells by regulating the protein expression of Bcl-2 and Caspase-3. ConclusionResveratrol can treat NAFLD in a multi-pathway and multi-target way. It mainly inhibits liver cell apoptosis by affecting the expression of Bcl-2 and Caspase-3， which provides a theoretical basis for the follow-up research on the anti-NAFLD mechanism of resveratrol.

Bowel preparation before elective surgery for colorectal cancer / 中华胃肠外科杂志

For elective surgery of colorectal cancer, current evidence supports preoperative mechanical bowel preparation combined with oral antibiotics. Meanwhile, for patients with varied degrees of intestinal stenosis, individualized protocol is required to avoid adverse events. We hereby summarize recent high-quality evidences and updates of guidelines and consensus, and recommend stratified bowel preparation based on the clinical practice of our institute as follows. (1) For patients with unimpaired oral intake, whose tumor can be passed by colonoscopy, mechanical bowel preparation and oral antibiotics are given. (2) For patients without symptoms of bowel obstruction but with impaired oral intake or incomplete colonoscopy due to tumor-related stenosis, small-dosage laxative is given for several days before surgery, and oral antibiotics the day before surgery. (3) For patients with bowel obstruction, mechanical bowel preparation or enema is not indicated. We proposed this evidence-based, individualized protocol for preoperative bowel preparation for the reference of our colleagues, in the hope of improving perioperative outcomes and reducing adverse events.

Antiosteoporosis Effect and Possible Mechanisms of the Ingredients of Fructus Psoraleae in Animal Models of Osteoporosis: A Preclinical Systematic Review and Meta-Analysis.

OBJECTIVE: Fructus Psoraleae (FP) and its ingredients (IFP) have a variety of biological activities and are widely used to treat osteoporosis (OP). Herein, we conducted a systematic review to evaluate the efficacy of IFP for an animal model of OP from the current literatures. Potential mechanisms of IFP in the treatment of OP were also summarized. MATERIALS AND METHODS: We carried out a search for electronic literature in the PubMed, Chinese National Knowledge Infrastructure, EMBASE, Wanfang, Web of Science, Chinese Biomedical Literature Database, and Cochrane Library, as well as Chinese VIP databases targeting articles published from inception to June 2021. The inclusion criteria were animal studies that assessed the efficacy and safety of IFP for OP, regardless of publication status or language. The exclusion criteria included (1) other types of studies (in vitro studies, case reports, clinical trials, reviews, abstracts, comments, and editorials), (2) combination with other compounds, (3) compared with other traditional Chinese medicine, (4) not osteoporosis or bone loss model, (5) studies with insufficient data, (6) lack of a control group, and (7) duplicate publications. The modified Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Stroke (CAMARADES) 10-item quality checklist was used to evaluate the risk of bias of included studies. We computed the relative risk (RR) and the standard mean difference (SMD) for dichotomous outcomes and continuous outcomes, respectively. When heterogeneity was detected or there was significant statistical heterogeneity (P < 0.05 or I 2 > 50%), a random-effects model was employed, followed by further subgroup analysis and metaregression estimations to ascertain the origins of heterogeneity. Otherwise, we used a fixed-effects model (P ≥ 0.05 or I 2 ≤ 50%). The primary outcome measures were bone mineral density (BMD), serum osteocalcin(S-OCN), bone volume over total volume (BV/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th), trabecular separation (Tb.Sp), bone maximum load, and elasticity modulus. The secondary outcome measure was the antiosteoporosis mechanisms of IFP. The STATA 12.0 software was used to analyze the data. RESULTS: Overall, 16 studies focusing on 379 animals were enrolled into the study. The risk of bias score of included studies ranged from 4 to 7 with an average score of 5.25. The present study provided the preliminary preclinical evidence that administration of IFP could significantly increase the S-OCN, BMD, BV/TV, and Tb.N while Tb.Th and Tb.Sp were remarkably decreased by IFP in OP model animals (P < 0.05). Moreover, IFP could significantly improve the bone biomechanical indicator bone maximum load and elasticity modulus (P < 0.05). In terms of the possible mechanisms of treatment of OP, IFP exerts anti-OP effects in animal models probably through osteoprotegerin/receptor activator of the nuclear factor-κB ligand/receptor activator of nuclear factor-κB (OPG/RANKL/RANK), peroxisome proliferator activated receptor γ (PPAR-γ)/Axin2/Wnt, antioxidative stress via forkhead box O3a (FoxO3a)/Axin2/Wnt, phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR), estrogen-like effect, and gamma-aminobutyric acid/gamma-aminobutyric acid receptor (GABA/GABABRI) signaling pathway. CONCLUSION: Taken together, the findings suggest the possibility of developing IFP as a drug or an ingredient in diet for the clinical treatment of OP. We recommend that rigorous, as well as high-quality, trials involving large sample sizes should be conducted to confirm our findings.

The Efficacy and Safety of Chinese Herbal Medicine Xianling Gubao Capsule Combined With Alendronate in the Treatment of Primary Osteoporosis: A Systematic Review and Meta-Analysis of 20 Randomized Controlled Trials.

Objective: Herein, we purposed to evaluate the efficacy along with the safety of Xianling Gubao capsule (XLGB) combined with alendronate (ALE) for primary osteoporosis (POP) from the current literature. Materials and Methods: We carried out a search for electronic literature in the PubMed, Chinese National Knowledge Infrastructure, EMBASE, Wanfang Web of Science, Chinese Biomedical Literature Database, Cochrane Library, as well as Chinese VIP databases targeting articles published from inception to December 2020. Only randomized controlled trials (RCTs) were enrolled into the study. Alkaline phosphatase (ALP), visual analogue scale (VAS), serum phosphorus (S-P), bone gla protein (BGP), serum calcium (S-Ca) and bone mineral density (BMD) were the primary outcome variable. The total clinical effective rate along with the adverse drug reaction (ADR) were the secondary outcome variables. The meta-analysis was conducted using RevMan 5.3 and STATA 12.0. GRADE pro3.6.1 software was used for the assessment of evidence quality. Results: Overall, 20 RCTs focusing on 1911 patients were enrolled into the study. Our meta-analysis demonstrated that XLGB combined with ALE remarkably increased BMD (p < 0.001), BGP (p < 0.001), S-Ca (p < 0.001), S-P (p < 0.001) and effective rate (p < 0.001) than ALE alone in patients with POP. Moreover, ALP (p < 0.001) and VAS (p < 0.001) were overtly by decreased XLGB. However, XLGB combined with ALE would not markedly increase the rate of ADR in contrast with ALE alone (p = 0.499). Conclusion: The results of our study demonstrated that XLGB is a potential candidate for OP treatment. We recommend that rigorous, as well as high-quality trials involving large samples sizes should be conducted to confirm our findings.

Objective:To investigate the short-term efficacy of Shenmai injection combined with FOLFOX chemotherapy in the treatment of advanced gastric cancer and its effects on immune function and tumor markers. Methods:Eighty-two patients with advanced gastric cancer who received treatment in Shengzhou Hospital of Traditional Chinese Medicine, China between June 2018 and June 2020 were included in this study. They were randomly assigned to receive either FOLFOX chemotherapy (control group, n = 41) or Shenmai injection combined with FOLFOX chemotherapy (observation group, n = 41). All patients received three 21-day courses of treatment. Short-term efficacy of chemotherapy and improvement in quality of life were compared between the two groups. Immune function, expression of tumor markers (carcinoembryonic antigen and carbohydrate antigen 724) and adverse reactions were determined before and after three courses of treatment. Results:Total effective rate in the observation group was significantly higher than that in the control group [70.73% (29/41) vs. 46.34% (19/41), χ2 = 5.025, P < 0.05]. The proportion of patients had improved quality of life in the observation group was significantly higher than that in the control group [78.05% (32/41) vs. 56.10% (23/41), χ2 = 4.473, P < 0.05]. After three courses of treatment, the proportion of CD 3+ and CD 4+ cells and the ratio of CD 4+/CD 8+ cells in the observation group were (58.39 ± 3.14)%, (38.79 ± 2.35)% and (1.54 ± 0.17), respectively, which were significantly higher than those in the control group [(48.10 ± 3.01)%, (30.10 ± 1.78)%, (0.92 ± 0.15), t = 15.148, 18.875, 17.511, all P < 0.05]. After three courses of treatment, serum carcinoembryonic antigen and carbohydrate antigen 724 levels in the observation group were (6.98 ± 1.45) μg/L and (7.85 ± 1.76) μg/L, respectively, which were significantly lower than those in the control group [(15.47 ± 3.21) μg/L, (18.97 ± 3.25) μg/L), t = 15.434, 19.265, both P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Shenmai injection combined with FOLFOX chemotherapy in the treatment of advanced gastric cancer exhibits good short-term efficacy, can improve the immune function, and reduce the levels of carcinoembryonic antigen and carbohydrate antigen 724.

Mechanism and experimental verification of Dachengqi Decoction in treatment of sepsis based on network pharmacology / 中国中药杂志

This study aims to predict the material basis and mechanism of Dachengqi Decoction in the treatment of sepsis based on network pharmacology. The chemical constituents and targets of Dachengqi Decoction were retrieved from TCMSP, UniPot and DrugBank and the targets for the treatment of sepsis from OMIM and GeneCards. The potential targets of Dachengqi Decoction for the treatment of sepsis were screened by OmicShare. STRING database and Cytoscape 3.7.2 were used to construct the Chinese medicinal-active component-target-disease, active component-key target-key pathway, and protein-protein interaction(PPT) networks. The gene ontology(GO) term enrichment analysis and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed by DAVID(P<0.05). Finally, the animal experiment was conducted to verify some targets and pathways. A total of 40 active components and 157 targets of the Dachengqi Decoction, 2 407 targets for the treatment of sepsis, and 91 common targets of the prescription and the disease were also obtained. The key targets were prostaglandin G/H synthase 2(PTGS2), prostaglandin G/H synthase 1(PTGS1), protein kinase cAMP-dependent catalytic-α(PRKACA), coagulation factor 2 receptor(F2 R), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic gamma subunit(PIK3 CG), dipeptidyl peptidase 4(DPP4), etc. A total of 533 terms and 125 pathways were obtained for the 91 targets. The main terms were the response to drug, negative regulation of apoptotic process, positive regulation of nitric oxide biosynthetic process and lipopolysaccharide-mediated signaling pathway, and the pathways included pathways in cancer, hepatitis B, and phosphatidylinositol 3-kinase and protein kinase B(PI3 K/Akt) signaling pathway. The animal experiment confirmed that Dachengqi Decoction can down-regulate inflammatory cytokines interleukin-1β(IL-1β), IL-6 and tumor necrosis factor α(TNF-α)(P<0.01). It could also reduce the wet/dry weight ratio of lung tissue, the level of myeloperoxidase(MPO) and the phosphorylation of PI3 K and Akt(P<0.01). These results indicated that Dchengqi Decoction could act on inflammation-related targets and improve sepsis by inhibiting PI3 K/Akt signaling pathway. The animal experiment supported the predictions of network pharmacology. Dachengqi Decoction intervenes sepsis via multiple components, multiple targets, and multiple pathways. The result lays a foundation for further research on the mechanism of Dachengqi Decoction in the treatment of sepsis.

OBJECTIVE@#To compare the application of multi-mode and single-mode intraoperative neurophysiological monitoring in the treatment of severe ossification of posterior longitudinal ligament of cervical spine with anterior cervical corpectomy with fusion.@*METHODS@#From April 2015 to June 2018, 32 patients with severe ossification of the posterior longitudinal ligament were treated in the Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine. There were 21 males and 11 females, aged 45 to 73 years old, with a mean age of 59 years old. The duration of the disease ranged from 6 to 72 months, with a mean of 39 months. The main manifestations were numbness, numbness and weakness of limbs, cotton feeling of foot stepping on lower limbs, instability of standing and walking. With the gradual aggravation of symptoms, quadriplegia, dysfunction of urine and defecation may occur. Patients with ossification of posterior longitudinal ligament of cervical spine were monitored by somatosensory evoked potentials, motor evoked potentials and electromyogram patterns.@*RESULTS@#During the operation, 8 patients had abnormal amplitude of somatosensory evoked potential(SEP); 5 of them had bleeding during anterior cervical decompression procedure and were placed with too much hemostatic cotton, which caused compression of spinal cord and resulted in abnormal SEP waveform. After removal of the hemostatic cotton, SEP waveform returned ot normal; 3 patients had abnormal SEP waveform due to decreased systolic pressure, which was corrected by increased systolic pressure. Twelve patients had abnormal amplitude of motor evoked potential during monitoring, 9 of which were caused by intraoperative mis-contact with nerve root, and turned to normal after timely adjustment of position, 3 of which were caused by intraoperative inhalation of muscle relaxant during surgery. Among 11 patients with abnormal EMG waveform, 9 patients recovered to normal waveform after adjusting operation, 2 patients recovered to normal waveform after short observation, and all patients recovered to normal waveform of motor evoked potential after operation(<0.05). There were 2 cases of cerebrospinal fluid leakage after operation, which healed spontaneously 7 days after operation, and no complications of spinal cord and nerve occurred in all patients after operation.@*CONCLUSIONS@#In anterior cervical corpectomy with fusion operation for the treatment of severe cervical ossification of posterior longitudinal ligament, various modes of intraoperative neurophysiological monitoring can real-time understand spinal cord and nerve function status, significantly reduce the incidence of spinal cord and nerve injury during operation, and effectively improve the safety of operation.

A total 168 cases eligible patients were randomly divided into the traditional Chinese medicine (TCM) group, the chemical medicine group and the TCM combined with chemical medicine group, with 56 cases in each group. The TCM group was treated with Sanbitang recipe; The chemical medicine group was given methotrexate tablets; And Sanbitang recipe and methotrexate tablets was adopted in the TCM combined with chemical medicine group. A course of treatment was 16 weeks. Health assessment questionnaire (HAQ), disease activity scores 28-joint counts (DAS28), visual analogue scale (VAS), TCM symptom, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), cyclic citrullinated peptides (CCP) and rheumatoid factor (RF) were detected. The efficiencies and incidence of adverse reactions in the three groups were compared. The total effective rate of the TCM combined with chemical medicine group was 92.7%, which was higher than 79.2% of the TCM group and 82.4% of the chemical medicine group (P<0.05). There was no statistically significant difference between the TCM group and the chemical medicine group. This suggested that Sanbitang recipe was effective in treating rheumatoid arthritis (RA) with kidney empty and cold-dampness symptom. After treatment, the scores of HAQ, DAS28, VAS, ESR, CRP, CCP and RF of the TCM combined with chemical medicine group were significantly higher (P<0.05) among the three groups. There was no statistically significant difference between the TCM group and the chemical medicine group. This indicated that Sanbitang recipe could effectively alleviate the clinical symptoms of rheumatoid arthritis (RA) with kidney empty and cold-dampness symptom. In terms of efficiency and incidence of adverse reactions, the order from low to high was that the TCM group (3.8%, 2/53)<the TCM combined with chemical medicine group (16.4%, 9/55)<the chemical medicine group (33.9%, 18/53) (P<0.05). Sanbitang recipe is effective in treating RA with kidney empty and cold-dampness symptom, with no obvious difference from methotrexate tablets and a low incidence of adverse reactions. Sanbitang recipe shows a remarkable effect in treating RA with kidney empty and cold-dampness symptom.

Structure-based virtual screening and characterization of a novel IL-6 antagonistic compound from synthetic compound database.

According to the three-dimensional (3D) complex structure of (hIL-6⋅hIL-6R⋅gp 130)2 and the binding orientation of hIL-6, three compounds with high affinity to hIL-6R and bioactivity to block hIL-6 in vitro were screened theoretically from the chemical databases, including 3D-Available Chemicals Directory (ACD) and MDL Drug Data Report (MDDR), by means of the computer-guided virtual screening method. Using distance geometry, molecular modeling and molecular dynamics trajectory analysis methods, the binding mode and binding energy of the three compounds were evaluated theoretically. Enzyme-linked immunosorbent assay analysis demonstrated that all the three compounds could block IL-6 binding to IL-6R specifically. However, only compound 1 could effectively antagonize the function of hIL-6 and inhibit the proliferation of XG-7 cells in a dose-dependent manner, whereas it showed no cytotoxicity to SP2/0 or L929 cells. These data demonstrated that the compound 1 could be a promising candidate of hIL-6 antagonist.

A polysaccharide purified from Radix Adenophorae promotes cell activation and pro-inflammatory cytokine production in murine RAW264.7 macrophages / 中国天然药物

Radix Adenophorae, a traditional Chinese medicine, has been reported to have a variety of biological functions. In the present study, a polysaccharide component, Radix Adenophorae Polysaccharide (RAPS), was purified from Radix Adenophorae by decoloring with ADS-7 macroporous adsorption resin, DEAE-52 cellulose ion-exchange chromatography, and Sephacryl S-300HR gel chromatography, with the purity of 98.3% and a molecular weight of 1.8 × 10(4) Da. The cell viability assay and microscopic examination revealed that RAPS promoted the proliferation and activation of macrophages. At 400 μg·mL(-1), RAPS stimulated RAW264.7 cell proliferation by 1.91-fold compared with the control. Meanwhile, RAPS significantly increased the secretion of pro-inflammatory cytokines (TNF-α and IL-6) in a dose-dependent manner in the supernatant of RAW264.7 cell culture as determined by ELISA. At 400 μg·mL(-1), the production of TNF-iα was 20.8-fold higher than that of the control. Simultaneously, the production of nitric oxide (NO) and the expression of inducible nitric oxide synthase (iNOS) were increased in RAW264.7 cells incubated with RAPS, as measured by Griess assay and Western blot analysis. The NO production of cells treated with RAPS (400 μg·mL(-1)) reached 15.8 μmol·L(-1), which was 30.4-fold higher than that of the control (0.53 μmol·L(-1)). These data suggested that RAPS may enhance the immune function and protect against exogenous pathogens by activating macrophages.

Synthesis and application of a fluorescent molecular probe for rapid detection of sulfur dioxide residues in traditional Chinese herbs / 中国药科大学学报

@#A fluorescence method based on a “turn-on” rhodamine derivative fluorescent probe was developed for the detection of hydrogen sulfite ions and sulfur dioxide residues in sulfur-fumigated herbs. This method was realized through a well-known aldehyde-bisulfite addition reaction accompanied by a ring opening of spirolactam of probe molecule in pH 4. 8 aqueous ethanol media which resulted in a significant fluorescence and color change. The fluorescence enhancement was linearly proportional to the concentrations of bisulfite ranging from 0. 005 to 20 μmol/L with a correlation coefficient of 0. 998 5. The detection limit was low as to 2. 0 nmol/L and there was no interference with other familiar co-existing anions, cations and reducing reagents indicating high sensitivity and selectivity of the proposed method. In addition, the novel probe was successfully applied for the identification of sulfur dioxide residues in herbs with a satisfactory recovery in five real samples.
