This study aims to evaluate the efficacy and safety of Guanxinning Tablets+conventional western medicine in the treatment of angina pectoris of coronary heart disease, and provide evidence-based references for clinical medication. Retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, randomized controlled trial(RCT) about Guanxinning Tablets for the treatment of angina pectoris of coronary heart disease from the inception to April 2022 were collected. After literature screening and data extraction, the bias risk assessment tool recommended by the Cochrane evaluation manual handbook 5.1.0 was used to evaluate the quality of the included literature, and RevMan 5.3 and Stata 14.0 were used for Meta-analysis. Eighteen RCTs were finally included, involving 2 281 patients. Meta-analysis showed that, compared with conventional western medicine treatment alone, Guanxinning Tablets+conventional western medicine significantly improved angina pectoris efficacy(RR=1.33, 95%CI[1.13, 1.57], P=0.000 8), electrocardiogram efficacy(RR=1.32, 95%CI[1.02, 1.71], P=0.03), and exercise duration(MD=59.53, 95%CI[39.16, 79.90], P<0.000 01) and reduced the incidence of cardiovascular events(MACE)(RR=0.43, 95%CI[0.30, 0.61], P<0.000 01), high sensitivity C-reactive protein(hs-CRP)(MD=-2.75, 95%CI[-3.71,-1.79], P<0.000 01), and endothelin-1(ET-1) levels(MD=-9.34, 95%CI[-11.36,-7.32], P<0.000 01). There was no statistically significant difference in the incidence of adverse reactions between two groups(RR=0.91, 95%CI[0.68, 1.22], P=0.52). Subgroup analysis showed that Guanxinning Tablets may have better short-term efficacy(less than 6 months) in the treatment of heart-blood stasis syndrome. GRADE grading showed that angina pectoris efficacy, electrocardiogram efficacy, MACE, and ET-1 were in the medium grade, hs-CRP and adverse reactions were in the low grade, and exercise duration was in the extremely low grade. In conclusion, the efficacy of Guanxinning Tablets+conventional western medicine is better than conventional western medicine treatment alone, with good safety. Therefore, it is recommended for the short-term treatment of patients with heart-blood stasis syndrome. However, the evidence quality of some results is low, and more rigo-rous RCT is still needed to enhance the reliability of evidence.

OBJECTIVESerum pregnancy-associated plasma protein A (PAPP-A) is increased in acute coronary syndrome patients and related to prognosis. We investigated the effects of C-reactive protein (CRP) and tumor necrosis factor-alpha (TNF-alpha) on PAPP-A mRNA expression in monocytes.
METHODSMonocytes were isolated by Ficoll density gradient centrifugation from blood of healthy volunteers. The PAPP-A expressions at mRNA level post CRP or rhTNF-alpha stimulation were measured by RT-PCR.
RESULTSPAPP-A mRNA expression in peripheral blood monocytes increased 2 hours (0.2128 +/- 0.0136) and peaked 24 hours (0.6837 +/- 0.1360) after CRP (20 mg/L) stimulation compared with control group (0.1842 +/- 0.0101). PAPP-A mRNA expression increased rapidly, peaked 2 hours (1.2546 +/- 0.0866) and remained elevated up to 24 hours (0.8203 +/- 0.0413) after rhTNF-alpha (100 ng/ml) stimulation. The effects of CRP and TNF-alpha were dose-dependent. PAPP-A mRNA expression of monocytes were 0.2544 +/- 0.0611, 0.4177 +/- 0.1200, 0.5828 +/- 0.0152, 0.6837 +/- 0.1360 after stimulated with CRP (1, 5, 10, 20 mg/L), and 0.2424 +/- 0.1378, 0.3335 +/- 0.0196, 0.5742 +/- 0.0131, 0.6913 +/- 0.0219 and 0.8203 +/- 0.0413 after stimulated with rhTNF-alpha (5, 10, 25, 50 and 100 ng/ml). Actinomycin D, the DNA-directed RNA polymerase inhibitor, completely blocked CRP and TNF-alpha induced PAPP-A expression.
CONCLUSIONSPAPP-A mRNA expression could be stimulated by CRP and TNF-alpha in human peripheral blood monocytes which might be responsible for the increased serum PAPP-A level in patients with acute coronary syndromes.

OBJECTIVETo study the clinical characteristics of neonatal sepsis caused by Klebsiella pneumoniae and the antibiotic sensitivity pattern of Klebsiella pneumoniae strains.
METHODSThe clinical data of 42 cases of neonatal sepsis caused by Klebsiella pneumoniae from January, 2000 to August, 2009 were retrospectively studied.
RESULTSThe clinical presentations were non-specific, including fever or hypothermia, tachypnea, apnea and feeding intolerance. C-reactive protein (CRP) level increased in 95% of the cases. The mortality was 21%. In neonates with early onset sepsis, Klebsiella pneumoniae strains were sensitive to amoxicillin/clavulanic-acid, piperacillin/tazobactam, cefoxitin, imipenem, cefoperazone/and sulbactam. In neonates with late onset sepsis, the sensitive antibiotics of Klebsiella pneumoniae strains were less, including cefoxitin, piperacillin/tazobactam and imipenem. Klebsiella pneumoniae strains were not sensitive to penicillins and cephalosporins in either neonates with early onset sepsis or late onset sepsis. The extended spectrum β-lactamases (ESBLs)-producing strains were found in 92% of the cases. The neonates with late onset sepsis presented a higher prevalence of ESBLs-producing strains than those with early onset sepsis (100% vs 70%; P<0.05).
CONCLUSIONSThe clinical manifestations of neonatal sepsis caused by Klebsiella pneumoniae are usually non-specific. CRP detection is valuable for early diagnosis of sepsis. There are differences in the antibiotic sensitivity of strains between the neonates with early onset and late onset Klebsiella pneumoniae sepsis.

OBJECTIVETo observe the protection effect of Ligustrazine Hydrochloride (LH) on coagulation reaction and inflammation reaction in single valve replacement patients with rheumatic heart disease undergoing cardiopulmonary bypass (CPB).
METHODSTotally 40 patients undergoing single valve replacement were recruited in the study and randomly assigned to the two groups, the treatment group and the control group, 20 in each group. In treatment group LH (3 mg/kg) was intravenously infused from the jugular vein. LH (3 mg/kg) was also added in the CPB priming. In the control group LH was replaced by equal amount of normal saline. Endothelial micro-particles (EMP) count was detected before CPB, 30 min after CPB, 1 h and 24 h after CPB finished. The coagulation reaction time (R), coagulation time (K), clotting formation velocity (alpha angle), maximum amplitude (MA), coagulation index (CI), platelet (PLT), hypersensitive C reactive protein (hs-CRP), IL-6, and IL-10 were detected before CPB, 1 h and 24 h after CPB finished.
RESULTSThere was no statistical difference in aorta arresting time, period of CPB, post-operative drainage volume, plasma transfusion volume, post-operative respirator assistant time, and hospitalization time between the two groups (P >0.05). Compared with pre-CPB in the same group, the count of EMP was much higher at 30 min after CPB and 1 h after CPB finished (P < 0.01). R and K, hs-CRP, IL-6, and IL-10 increased at 1 h and 24 h after CPB finished (P <0.01,P < 0.05). The alpha angle,.MA, CI, and PLT decreased 1 h after CPB finished (P <0.01). The a angle increased, while CI and PLT decreased 24 h after CPB finished (P <0.05). Compared with the control group in the same period, the count of EMP was lower in the treatment group 30 min after CPB and 1 h after CPB finished (P <0. 05, P <0. 01). R and K values obviously decreased in treatment group 1 hour after CPB finished (P <0. 05), while a angle, MA, CI, and PLT increased (P <0. 05, P <0. 01). hs-CRP and IL-6 decreased in the treatment group 1 h and 24 h after CPB finished (P <0.05), while IL-10 increased (P <0.05). The count of PLT increased 24 h after CPB finished in the treatment group (P <0. 05).
CONCLUSIONLH had certain protection effect on the vascular endothelium undergoing CPB, and lower excessive activation of coagulation reaction and inflammation reaction in patients undergoing CPB.

This study aims to systematically review the efficacy and safety of different traditional Chinese medicine injections combined with conventional treatment for patients with post-acute myocardial infarction heart failure. The relevant randomized controlled trial(RCT) was retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library with the time interval from inception to May 13, 2023. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Network Meta-analysis was then performed in RevMan 5.3 and Stata 15.1. A total of 68 RCTs involving 11 traditional Chinese medicine injections and 5 995 patients were included. The results were explained based on the surface under the cumulative ranking curve(SUCRA).(1) In terms of reducing major adverse cardiovascular event(MACE), the therapies followed the trend of Xinmailong Injection+conventional treatment(83.8%) > Yiqi Fumai Injection+conventional treatment(57.1%) > Xuebijing Injection+conventional treatment(56.6%) > Shenmai Injection+conventional treatment(53.1%) > Shenfu Injection+conventional treatment(45.3%) > conventional treatment(4.0%).(2) In terms of increasing left ventricular ejection fraction(LVEF), the therapies followed the trend of Yiqi Fumai Injection+conventional treatment(84.0%) > Shenmai Injection+conventional treatment(69.6%) > Shenfu Injection+conventional treatment(62.7%) > Xinmailong Injection+conventional treatment(61.6%) > Shuxuening Injection+conventional treatment(54.8%) > Shenqi Fuzheng Injection+conventional treatment(46.7%) > Shengmai Injection+conventional treatment(45.9%) > Breviscapine Injection+conventional treatment(39.9%) > Danhong Injection+conventional treatment(38.8%) > Huangqi Injection+conventional treatment(38.7%) > conventional treatment(7.3%).(3) In terms of reducing B-type natriuretic peptide(BNP), the therapies followed the trend of Xinmailong Injection+conventional treatment(98.6%) > Shenmai Injection+conventional treatment(57.7%) > Shenfu Injection+conventional treatment(52.5%) > Shengmai Injection+conventional treatment(30.1%) > conventional treatment(11.0%).(4) In terms of reducing cardiac troponin Ⅰ(cTnⅠ), the therapies followed the trend of Shenmai Injection+conventional treatment(92.3%) > Yiqi Fumai Injection+conventional treatment(61.5%) > Shenfu Injection+conventional treatment(51.2%) > Shengmai Injection+conventional treatment(48.1%) > Xinmailong Injection+conventional treatment(26.6%) > conventional treatment(20.3%).(5) In terms of reducing high-sensitivity C-reactive protein(hs-CRP), the therapies followed the trend of Shenmai Injection+conventional treatment(79.9%) > Xinmailong Injection+conventional treatment(68.1%) > Shenfu Injection+conventional treatment(63.1%) > Xuebijing Injection+conventional treatment(56.7%) > Shengmai Injection+conventional treatment(51.1%) > Shenqi Fuzheng Injection+conventional treatment(42.8%) > Huangqi Injection+conventional treatment(34.7%) > conventional treatment(3.5%).(6) A total of 22 RCTs reported the occurrence of adverse reactions, mainly involving the damage of the circulatory system, digestive system, and coagulation function. The current evidence suggested that Xinmailong Injection+conventional treatment may have the best therapeutic effect in reducing MACE and BNP; Yiqi Fumai Injection+conventional treatment may be the best in increasing LVEF; Shenmai Injection+conventional treatment may be the best in reducing cTnI and hs-CRP. The safety needs further quantitative research and analysis. However, more high-quality RCT is required to validate the above conclusions due to limitations in the quality and quantity of the included studies.

OBJECTIVETo evaluate the efficacy and safety of Tripterygium wilfordii extract (TWE) in treating rheumatoid arthritis.
METHODMainly using the simple methods from the International Cochrane Collaboration as systematic evaluation methods. Using Revman 4.2.5 which Cochrane Cooperation Web recommended to analysis. Using American College of Rheumatology (ACR) core set (ACR20, ACR50, and ACR70) of therapeutic efficacy measures which recommended by ACR, radiographic change of bone and the rate of inefficacy as efficacy methods. Dividing into placebo subgroup and DMARDs (disease modifying anti rheumatism drugs) subgroup according to different control treatments.
RESULTA total of seven randomized controlled trials (RCTs) were collected. They are all of small sample size, six of which exist some methodological defects, resulting in many possible biases. As evaluated by ACR20/50/70, TWE was as effective as DMARDs in reducing number of swelling joints, level of C-reactive protein (CRP), and was more effective than DMARDs in reducing erythrocyte sedimentation rate (ESR) (P <0.01). While TWE was no effect in delaying bone destruction. The incidence of adverse reactions of TWE is higher than DMARDs.
CONCLUSIONTWE can be used as an alternative medicine in treating RA. But owing to lacking of data from high-quality RCTs, however, the efficacy and safety of TWE are desired for further exploration.

OBJECTIVETo investigate the effects of 17β-estrogen on expressions of C-reactive protein (CRP) and its mRNA in vascular smooth muscle cells(VSMCs).
METHODSImmunocytochemistry was used to detect CRP level in normal VSMCs. The expressions of C-reactive protein and p-ERK1/2 in Ang-II-stimulated VSMCs were evaluated with Western blot. C-reactive protein mRNA was examined with RT-PCR.
RESULTS17β-estrogen had no effect on cell morphology and C-reactive protein expression in normal VSMCs; however, C-reactive protein and mRNA, as well as p-ERK1/2 were decreased in Ang-II-stimulated VSMCs after 17β-estrogen treatment in a concentration-dependent manner.
CONCLUSION17β-estrogen may inhibit the expression of C-reactive protein and its mRNA in Ang-II-stimulated VSMCs via ERK1/2 signal transduction pathway in a concentration-dependent way.

OBJECTIVETo observe the expression and localization of endogenous C-reactive protein (CRP) in cells from different tissues under different conditions.
METHODSMacrophages differentiated from THP-1 monocytes with phorbol ester (PMA) induction and human LO2 hepatocytes were stimulated with lipopolysaccharide (LPS). The culture supernatant of the LPS-stimulated THP-1 cells was collected and added into LO2 cell culture, and after incubation, the cells were lysed to extract the proteins for SDS-PAGE and Western blotting. The stimulated cells were also examined immunocytochemically for CRP expression.
RESULTSWestern blotting detected CRP in both of the unstimulated cell lysates, but in neither of the two cell supernatants. After LPS stimulation, CRP expression was significantly increased in the cell lysate of THP-1 cells with also a small amount present in the supernatant, but CRP expression and release in the LO2 cells showed no significant variation. Treatment of the LO2 cells with the culture supernatant of LPS-stimulated THP-1 cells resulted in positivity of CRP in the cell lysate and the culture supernatant. Immunocytochemistry identified CRP expression throughout the THP-1 cell body (most obvious in the nuclei), which increased after LPS stimulation. In LO2 hepatocytes, CRP expression was found only outside the nuclei and increased after stimulation with the culture supernatant of LPS-treated THP-1 cells, especially obvious around the membrane.
CONCLUSIONCRP can not be up-regulated directly by LPS treatment in LO2 cells, but can be induced by certain cytokines (IL-6) secreted from LPS-stimulated THP-1 cells. The localization of CRP represents the characteristics of secreted protein in LO2 cells, but in THP-1 cells, CRP is found mainly in the cell nuclei.

Chinese Medical Journal 2009;122(16):1922-1928
BACKGROUNDC-reactive protein (CRP) has been reported to damage the vascular wall by inducing endothelial dysfunction and inflammation, and it is also speculated to have a role in attenuating angiogenic functions of human endothelial progenitor cells (EPCs). Interleukin-8 (IL-8) is an important mediator of the paracrine mitogenic effect of EPCs, which has direct angiogenic effects on mature endothelial cells. We, herein, investigated the direct effect of CRP on IL-8 production and gene expression in cultured human EPCs.
METHODSEPCs were isolated from the peripheral venous blood of healthy male volunteers. Cells were cultured in EndoCult liquid medium in the absence and presence of CRP at clinically relevant concentrations (5 to 25 microg/ml) for different durations (3 to 48 hours). IL-8 protein and mRNA of cultured EPCs were evaluated using ELISA and real-time PCR.
RESULTSThe results showed that CRP at a concentration of 10 microg/ml significantly reduced IL-8 secretion of cultured EPCs with a peak at 25 microg/ml, and also decreased mRNA expression in EPCs with a peak at 12 hours. In addition, preincubation of EPCs with SB203580, an inhibitor of p38 mitogen-activated protein kinase (MAPK) decreased CRP inhibition of IL-8 mRNA expression at 12 hours in EPCs.
CONCLUSIONSOur study, for the first time, demonstrates that CRP directly inhibits EPCs IL-8 secretion, a key cytokine player of angiogenesis induced by EPCs. Inhibition occurred in part via an effect of CRP to active the p38 MAPK signal transduction pathway in EPC. The ability of CRP to inhibit EPCs IL-8 secretion may represent an important mechanism that further links inflammation to cardiovascular disease.

Journal of Preventive Medicine and Public Health 2012;45(2):62-69
OBJECTIVES: Chronic inflammation is now thought to play a key pathogenetic role in the associations of obesity with insulin resistance and diabetes. Based on our recent findings on persistent organic pollutants (POPs) including the lack of an association between obesity and either insulin resistance or diabetes prevalence among subjects with very low concentrations of POPs, we hypothesized that POP concentrations may be associated with inflammation and modify the associations between inflammation and insulin resistance in non-diabetic subjects. METHODS: Cross-sectional associations among serum POPs, C-reactive protein (CRP), and homeostasis model assessment of insulin resistance (HOMA-IR) were investigated in 748 non-diabetic participants aged > or =20 years. Nineteen types of POPs in 5 subclasses were selected because the POPs were detectable in > or =60% of the participants. RESULTS: Among the five subclasses of POPs, only organochlorine (OC) pesticides showed positive associations with CRP concentrations, while polychlorinated biphenyls (PCBs) showed inverse associations with CRP concentrations. There were statistically significant interactions between CRP and OC pesticides and between CRP and PCBs, in estimating HOMA-IR (P for interaction <0.01 and <0.01, respectively). CRP was not associated with HOMA-IR among subjects with low concentrations of OC pesticides or PCBs, while CRP was strongly associated with HOMA-IR among subjects with high concentrations of these POPs. CONCLUSIONS: In the current study, OC pesticides were associated with increased levels of CRP, a marker of inflammation, and both OC pesticides and PCBs may also modify the associations between CRP and insulin resistance.
