Role of inflammatory factors in diabetic ulcers and prospects of traditional Chinese medicine intervention / 中国组织工程研究

BACKGROUND:Diabetic ulcers are a common complication of diabetes mellitus,which is manifested as foot ulcers complicated with infection,long treatment cycle,high disability rate and mortality rate,and brings a heavy burden to patients and social care. OBJECTIVE:To review the mechanism of action and the latest treatment progress of traditional Chinese medicine(TCM)in the treatment of diabetic ulcers,and to provide a basis for further theoretical research and clinical application. METHODS:CNKI,WanFang Database and PubMed database were searched for relevant literature using the keywords of"diabetic ulcer,medicinal herb,inflammation,interleukin-1β,interleukin-6,tumor necrosis factor,hypersensitive C-reactive protein,γ-interferon,interleukin-4,interleukin-10"in Chinese and English,respectively.The relevant literature in recent years was searched,and finally 75 articles were included for review. RESULTS AND CONCLUSION:The high glucose environment of the body will increase the level of pro-inflammatory cytokines,so that diabetic ulcer wounds are in a state of chronic inflammatory response for a long time,and difficult to heal or even not heal.TCM has summed up a lot of experience in the long-term struggle with diabetic ulcer.At present,TCM divides diabetic ulcers into four syndrome types:dampness and heat poison syndrome,blood and blood stasis obstruction pattern,heat poison injury Yin pattern,and Qi and blood deficiency syndrome,as well as representative prescriptions for treatment.According to their clinical characteristics,diabetic ulcers can be also divided into three stages:primary,middle and late stages.Different treatment methods are proposed:"clear method,""warm and clear combined use"and"maintenance method."Under the guidance of dialectical typing and staging of TCM,TCM monomers,extracts and compounds inhibit the inflammatory response and promote the healing of diabetic ulcers by down-regulating the expression of pro-inflammatory factors and/or up-regulating the expression of anti-inflammatory factors.Compared with modern medicine,TCM has significant advantages in the treatment of diabetic ulcers.There are many TCM monomers,extracts and compounds for the treatment of diabetic ulcers,such as angelica,curcumin,improved Chonghe ointment,Sanhuang blood exhaustion prescription and sore-ulcer I.formula,etc.It has been found that TCM for the treatment of diabetic ulcers is mainly heat-clearing and detoxifying,invigorating blood circulation and removing blood stasis,and amassing sores and muscle-building drugs,and the frequency of use,treatment scope and therapeutic effect of TCM compounds are obviously better than those of TCM monomers and extracts.Among them,the most commonly used are the Sanhuang blood exhaustion prescription and the sore-ulcer I as well as prescription for the treatment of damp heat toxicity syndrome and Zizhu ointment for the treatment of non-ischemic diabetic ulcers.However,there are also some shortcomings in the treatment of diabetic ulcers with TCM.First,there are few clinical syndrome studies on diabetic ulcers.Secondly,there are a wide variety of TCM monomers,extracts and compounds for the treatment of diabetic ulcers,and the relevant research is insufficiently in-depth.Finally,the research on the mechanism underlying TCM treatment of diabetic ulcers is still in the preliminary exploration stage,and the mechanism of action still needs to be further explored.In the future,it is necessary to strengthen the research on the pharmacology of TCM and the clinical syndrome of diabetic ulcers,analyze the potential targets and related signaling pathways of TCM in the treatment of diabetic ulcers,give full play to the therapeutic advantages of TCM with multiple targets,multiple pathways,multiple levels and multiple systems,and develop TCM with significant efficacy,active ingredients and clear targets.

@#Objective To investigate the diagnostic value and clinical significance of hypersensitive C-reactive protein(hs-CRP),procalcitonin(PCT)combined with interleukin-6(IL-6)in children with severe hand-foot-mouth disease.Methods A total of 62 children hospitalized in our hospital from January 2022 to December 2022 were collected as research objects.According to the severity of infection,they were divided into observation group(severe infection group)with 29 cases and control group(mild infection group)with 33 cases.The differences of general data,total leukocyte count,neutrophil count,lymphocyte count,platelet count,hs-CRP,PCT,IL-6 and creatine kinase isoenzyme(CK-MB)between the two groups and their clinical applications were analyzed and compared.Results The total white blood cell count,neutrophil count,lymphocyte count,hs-CRP,PCT and IL-6 in the observation group were higher than those in the control group,and the difference has statistically significant.Receiver operator characteristic(ROC)curve analysis of hs-CRP predicted the sensitivity and specificity of severe infection of hand-foot-mouth disease were 79.3%and 93.9%(95%CI:0.852-10.985,P<0.05);The sensitivity and specificity of PCT were 93.1%and 84.8%(95%CI:0.907-1,P<0.05);The sensitivity and specificity of IL-6 were 96.6%and 87.9%(95%CI:0.945-1,P<0.05).Conclusions In hand-foot-mouth classification,PCT and IL-6 are highly sensitive.Although hs-CRP is less sensitive than the former,its specificity is higher than the former.Therefore,the combination of hs-CRP,PCT and IL-6 has higher value for hand-foot-mouth classification.

Correlation between levels of hs-CRP and PCT in serum and alveolar fluid and disease severity in children with lobar pneumonia / 中国热带医学

@#Abstract: Objective　To explore the correlation between levels of hypersensitive C-reactive protein (hs-CRP) and procalcitonin (PCT) in serum and alveolar fluid and severity of disease in children with lobar pneumonia. Methods　A total of 112 children diagnosed with lobar pneumonia from September 2020 to September 2021 were selected as the research subjects. The levels of hs-CRP and PCT in serum and alveolar fluid were detected by double antibody sandwich enzyme-linked immunosorbent assay (ELISA). The children were divided into severe group (clinical pulmonary infection score, CPIS≥6 points) and mild group (CPIS<6 points) according to the severity of disease, and further classified into good prognosis group (cured, improved) and poor prognosis group (uncured) according to their treatment outcomes. The correlation of levels of hs-CRP and PCT in serum and alveolar fluid with disease severity in children and their predictive value on prognosis were analyzed. Results　The levels of serum hs-CRP and PCT in severe group were (17.73±3.26) μg/L and (8.59±1.84) μg/L, which were significantly higher than corresponding (12.58±3.09) μg/L, and (5.62±1.59) μg/L in mild group (P<0.05); the levels of hs-CRP and PCT in alveolar fluid in severe group were (21.25±4.18) μg/L and (8.71±1.54) μg/L, which were significantly higher than corresponding (13.79±2.76) μg/L and (5.38±1.69) μg/L in mild group (P<0.05). The levels of hs-CRP and PCT in serum and alveolar fluid were positively correlated with CPIS scores (r=0.398, 0.441; 0.475, 0.586, P<0.05). The levels of hs-CRP and PCT in serum in poor prognosis group were (20.09±4.20) μg/L and (13.35±2.91) μg/L, which were significantly higher corresponding (8.75±2.19) μg/L and (6.28±1.31) μg/L in good prognosis group (P<0.05). The levels of hs-CRP and PCT in alveolar fluid were (23.70±4.29) μg/L and (10.73±2.04) μg/L, which were higher than corresponding (15.08±3.56) μg/L and (5.79±1.10) μg/L in poor prognosis group (P<0.05). There was no significant difference in AUC between combined detection of serum indicators and combined detection of alveolar perfusion fluid indicators in predicting the prognosis of children with lobar pneumonia (P>0.05). Conclusions　The levels of hs-CRP and PCT in serum and alveolar fluid of children with lobar pneumonia are significantly increased and positively correlated with the severity of disease. However, the predictive value of the combined detection of serum indicators and combined detection of alveolar perfusion fluid indicators for the prognosis of children with lobar pneumonia is comparable.

Expression of adiponectin receptor T-cadherin in acute myocardial infarction and its association with acute inflammatory reaction / 中华急诊医学杂志

Objective:To study the expression of adiponectin receptor T-cadherin in ISO-induced rat myocardial infarction model and its association with acute inflammatory reaction.Methods:Twenty-four male Wistar rats were randomly divided into the myocardial infarction model group and the control group, with 12 rats in each group. After normal electrocardiogram recording, rats in the myocardial infarction model group were injected subcutaneously with isoproterenol (ISO) 150 mg·kg -1·d -1 for 2 consecutive days. The control group was subcutaneously injected with the same amount of normal saline for 2 consecutive days. Electrocardiogram was recorded 24 h after the second subcutaneous injection of ISO. After the success of the model, the rats were sacrificed, the heart tissue was stained with HE, and the protein expression of T-cadherin in the myocardium was detected by immunohistochemistry. The levels of adiponectin, T-cadherin, hypersensitive C-reactive protein (hS-CRP) and tumor necrosis factor alpha (TNF-α) in serum were detected by ELISA. Results:Immunohistochemical results showed that the protein expression of T-cadherin decreased in the myocardial infarction model group [(0.1567±0.0061) vs. (0.1228±0.0027)], and the difference was statistically significant ( P<0.05). ELISA showed that serum adiponectin (ng/mL) content in the myocardial infarction model group was significantly decreased [(7.016±0.7236) vs. (1.883±0.2240)], and the difference between the two groups was statistically significant ( P<0.01). Serum T-cadherin (ng/mL) [(6.075±0.8149) vs. (14.610±1.583)], serum TNF-α (pg/mL) [(1860±95.96) vs. (3141±92.5)] and serum hs-CRP (ng/mL) [(20.93±1.079) vs. (30.49±1.742)] in the myocardial infarction model group were significantly increased, and the differences between the two groups were statistically significant ( P<0.01). Serum T-cadherin was negatively correlated with serum adiponectin, and serum T-cadherin was positively correlated with inflammatory factors (TNF-α and hs-CRP), while serum adiponectin was negatively correlated with inflammatory factors (TNF-α and hs-CRP). Conclusions:T-cadherin is involved in the inflammatory response of acute myocardial infarction, which may be an important molecular marker of acute myocardial injury and play an important role in the disease early warning.

Application value of SONG-HD scale in evaluating fatigue level of patients undergoing hemodialysis and analysis of factors influencing fatigue / 中国基层医药

Objective:To investigate the application value of standardized outcomes in nephrology hemodialysis (SONG-HD) scale in evaluating the fatigue level of patients undergoing maintenance hemodialysis (MHD) patients and the factors that affect fatigue.Methods:A total of 201 patients undergoing regular MHD who received treatment in the Department of Nephrology, The First Affiliated Hospital of Xiamen University in April 2021 were included in April, 2021. The SONG-HD scale was used to evaluate patient's fatigue level. Fatigue was assessed using face-to-face interview questionnaire. Clinical and laboratory indicators were analyzed. Univariate logistic regression analysis and multivariate logistic regression analysis were performed to analyze the factors that affect fatigue of patients undergoing MHD.Results:Among the 201 MHD patients, 73.1% (147/201) had fatigue. The high-sensitivity C-reactive protein and parathyroid hormone levels in patients with fatigue were 0.91 (0.30, 3.63) mg/L and 216.00 (141.00, 347.00) ng/L, respectively, which were significantly higher than 0.40 (0.30, 2.01) mg/L and 153.00 (96.73, 308.50) ng/L in patients who had no fatigue ( Z = 2.12, 2.17, both P < 0.05). The pre-dialysis carbon dioxide binding capacity and blood albumin levels in patients who had fatigue were (21.03 ± 2.65) mmol/L and (36.76 ± 3.20) g/L, respectively, which were significantly lower than (22.68 ± 3.01) mmol/L and (38.61 ± 2.85) g/L in patients who had no fatigue ( t = 3.77, 3.73, both P < 0.05). Univariate logistic regression analysis showed that high-sensitivity C-reactive protein, pre-dialysis carbon dioxide binding capacity, serum albumin level, and parathyroid hormone level were related to the occurrence of fatigue in patients undergoing MHD ( Wald = 4.32, 12.39, 12.23, 4.66, all P < 0.05). Additionally, in a multivariate model adjusted for confounding factors, the independent risk factors for fatigue in patients undergoing MHD were relatively low pre-dialysis carbon dioxide binding capacity and serum albumin level ( Wald = 12.41, 11.67, both P < 0.05). Conclusion:The incidence of fatigue is high in patients undergoing MHD. The SONG-HD scale is convenient to use in assessing the fatigue level of patients undergoing MHD. After adjusting for confounding factors, fatigue in patients undergoing MHD is associated with reduced levels of pre-dialysis carbon dioxide binding capacity and serum albumin.

Predictive value of preoperative left atrial diameter in the occurrence of postoperative atrial fibrillation after coronary artery bypass grafting / 中华胸心血管外科杂志

Objective:To investigate the predictive value of preoperative left atrial diameter in postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG) in patients with coronary artery disease (CAD) and its influencing factors.Methods:This study was a prospective observational study. A total of 113 patients with CABG surgery were enrolled in Beijing Anzhen Hospital affiliated to Capital Medical University from January 2020 to December 2020. Preoperative coronary angiography, echocardiography and blood test were finished. The number of graft vessel was counted during the operation. The occurrence of POAF was confirmed by electrocardiogram or electrocardiograph monitoring after surgery. The preoperative baseline data, blood test, perioperative complications and other indicators of patients with or without POAF were compared.Results:According to the inclusion criteria and exclusion criteria, 90 patients undergoing CABG were enrolled in the study[71 males and 19 females, aged from 42 to 75, mean age (62±8)years old]. The incidence of POAF was 27.8%(25 cases). The left atrial diameter[40(36-43)mm vs. 35(33-37)mm, P=0.00]and troponin I[4.76(0.87-13.60)ng/ml vs. 1.48(0.56-4.52)ng/ml, P=0.04] in patients with POAF were significantly higher than that in patients without POAF. Compared to patients without POAF, POAF significantly increased the incidence of stroke[4(16%) vs. 0(0), P=0.01], ICU stay[67(24-96) days vs. 22(19-41) days, P=0.00] and hospital stay[21(19-24) days vs. 16(14-24) days, P=0.05]. Binary logistic regression showed that left atrial diameter was significantly correlated with the occurrence of POAF ( OR=1.9, 95% CI: 1.39-2.79, P<0.001). ROC curve analysis showed that 40 mm of left atrial diameter was a predictor of POAF( AUC=0.82, sensitivity 52%, specificity 100%, P<0.001). Linear regression analysis showed that left atrial diameter was significantly positively correlated with hypersensitive C-reactive protein ( Beta=0.24, 95% CI: 0.00-0.26, P=0.043). Conclusion:POAF significantly increased the incidence of stroke after CABG. Preoperative left atrial diameter is an independent predictor for POAF, which is closely related to the systemic inflammatory response.

Objective:To correlate peripheral blood hypersensitive C-reactive protein (hs-CRP) with cognitive function in patients with depression.Methods:Seventy-five patients with depression who received treatment in the Second People's Hospital of Lishui from January 2019 to May 2020 were included in the depression group. An additional 50 healthy controls were included in the control group. The MATRICS Consensus Cognitive Battery (MCCB) was used to evaluate participates' cognitive function. Serum hs-CRP level was determined using enzyme-linked immunosorbent assay.Results:Speed of processing, working memory, verbal learning, visual learning and reasoning/problem-solving scores in the depression group were significantly lower than those in the control group ( t = 10.774, 2.774, 9.840, 5.064, 7.915, all P < 0.01). Serum hs-CRP level in the depression group was significantly higher than that in the control group [(13.05 ± 2.94) mL vs. (1.13 ± 0.18) mL, t = 28.595, P < 0.01]. Speed of processing, working memory, verbal learning, visual learning and reasoning/problem-solving scores in patients with moderate and severe depression were significantly lower than those in patients with mild depression. Serum hs-CRP level in patients with moderate and severe depression was (10.41 ± 2.21) mg/L and (25.71 ± 4.04) mg/L, respectively, which was significantly higher than that in patients with mild depression [(3.03 ± 0.49) mg/L, t = 3.015, 3.370; 3.903, 3.441; 3.541, 3.604; 4.503, 4.661; 4.001, 3.980; 4.035, 3.669, all P < 0.01]. Speed of processing, working memory, verbal learning, visual learning and reasoning/problem-solving scores in patients with severe depression were significantly lower than those in patients with moderate depression ( t = 8.331, 5.227, 10.031, 6.003, 9.416, all P < 0.01). Serum hs-CRP level in patients with severe depression was significantly higher than that in patients with moderate depression [(25.71 ± 4.04) mg/L vs. (10.41 ± 2.21) mg/L, t = 11.005, P < 0.01]. Pearson correlation analysis showed that serum hs-CRP level in patients with depression was remarkably negatively correlated with speed of processing, working memory, verbal learning, visual learning and reasoning/problem-solving scores (all P < 0.01). Conclusion:Serum hs-CRP level in patients with depression is greatly increased, can reflect the severity of depression and is related to cognitive function.

Analysis of clinical features and related factors of coronavirus disease 2019 in Shanghai / 上海交通大学学报（医学版）

Objective • To explore the common clinical features of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)-infected local patients in Shanghai and their related influencing factors. Methods • A total of 320 patients admitted to Shanghai Public Health Clinical Center from January to March 2020 and diagnosed as having coronavirus disease 2019(COVID-19) were selected. Clinical data of the patients were collected to analyze their characteristics. Using the statistical operation formula of R language, the correlation analysis of hospitalization days, days of increased hypersensitive C-reactive protein concentration (allergic days), days of lung CT improvement (CT days), and days required for nucleic acid turning negative with the main clinical manifestations and laboratory data was carried out. The correlation factors affecting the above four variables were analyzed. Results • Among the 320 patients, the proportions of mild type, moderate type, serious type and critical type were 6.25%, 83.44%, 6.88% and 3.44%, respectively; 91.25% of them had a history of exposure to Hubei. The proportions of fever, cough, sputum and fatigue were 79.06%, 46.56%, 21.56% and 15.31%, respectively. Spearman correlation analysis showed that the concentrations of lactate dehydrogenase, interleukin-2(IL-2) and IL-6 were positively correlated with the above four variables, respectively (all P<0.05), albumin concentration was negatively correlated with allergic days (P=0.018), and CD4+ cell count was negatively correlated with CT days and days required for nucleic acid turning negative (both P<0.05). Stepwise multiple linear regression analysis showed that procalcitonin (PCT) concentration was negatively correlated with hospitalization days, CT days and allergic days (both P<0.05), and disease type was positively correlated with hospitalization days, allergic days, CT days and days required for nucleic acid turning negative (all P<0.05). Conclusion • Moderate type is common in the local patients in Shanghai; fever, cough and fatigue are common symptoms, and most of the patients are accompanied by lung CT abnormalities. The therapeutic effect and prognosis of these patients are closely related to disease type, concentrations of PCT and IL-6, as well as CD4+ cell count.

Objective To investigate the correction between the levels of vascular endothelial growth factor (VEGF), serum amyloid A (SAA), hypersensitive C-reactive protein (hs-CRP) and acute cerebral infarction (ACI), and to provide the basis for the diagnosis and treatment of ACI.Methods A total of 76patients with ACI in the hospital from August to October 2017were selected as ACI group.In addition, 32healthy subjects underwent physical examination in the same period in this hospital were selected as negative control group (NC group).The levels of SAA and hs-CRP were detected by nephelometry, while the level of VEGF was measured by enzyme-linked immunosorbent assay (ELISA).The differences of detection indexes between two groups were compared, and the diagnostic value of each index and the combined test were evaluated with the Youden index.Results The levels of SAA, hs-CRP and VEGF in ACI group, were significantly higher than those of NC group (P＜0.01).The levels of VEGF was positively correlated with SAA and hs-CRP (r=0.434and0.631, P=0.000and 0.000).The optimal diagnostic critical points of VEGF, SAA and hs-CRP in the diagnosis of ACI were 161.93pg/mL, 3.81mg/L and 4.63mg/L, and the sensitivities were 93.55％, 65.91％and64.44％, the specificities were 60.00％, 93.75％and 90.32％, respectively.Combined detection with hs-CRP and VEGF was superior to single index detection and other joint detection.The sensitivity, specificity and Youden index of combined detection with hs-CRP and VEGF were 96.67％, 95.65％and 0.92respectively.Conclusion The levels of VEGF, SAA and hs-CRP increase in patients with ACI, and they play important roles in the diagnosis of ACI.VEGF are positively related to SAA and hs-CRP, and there may be an synergistic effect exist.VEGF may be involved in the pathological process of cerebral infarction.The combined detection of hs-CRP and VEGF is of high clinical value in the diagnosis of cerebral infarction.

Effects of Sacubitril/Valsartan on biochemical indicators and on left ventricular structure in NYHA Ⅳ heart failure with reduced ejection fraction patients / 中华老年医学杂志

Objective To investigate the effects of Sacubitril/Valsartan on amino terminal probrain natriuretic peptide (NT-proBNP),high sensitivity C-reactive protein (hs-CRP),soluble suppression of tumorigenicity 2(sST2)levels and on left ventricular(LV)structure in NYHA Ⅳ heart failure with reduced ejection fraction(HFrEF) patients.Methods A total of 67 HFrEF patients with NYHA Ⅳ were randomly divided into the control group (n =30)receiving conventional medical treatment,and the observation group(n=32)receiving Sacubitril/Valsartan instead of ACEI(or ARB if ACEI induced cough) in conventional medical treatment.NT-proBNP levels were determined by fluorescer-enhanced chemiluminescence.hs CRP levels were detected by latecx enhanced immunoturbidimetric assay.sST2 levels were determined by enzyme-linked immunosorbent assay (ELISA).The modified Simpson method was used to detect left ventricular end-diastolic diameter (LVEDD),LV posterior wall(LVPW)and LV ejection fraction(LVEF).Two groups of patients were treated and followed-up for 6 months.Results Clinical efficacy was better in the observation group than in the control group(effective rate,20 cases or 61.3％ vs.8 cases or 26.7％,P＜0.05).As compared with the control group,the observation group of patients had an increased LVEF[(46.7±9.2) ％ vs.(41.8±8.0)％,P＜0.05]and a decreased LVEDD[(52.6±6.7)mm vs.(58.8±7.5)mm,P＜0.05].After vs.before treatment,NT-proBNP,hs-CRP and sST2 levels were decreased in both control and observation groups [(1 427 ± 219) μg/L vs.(2 615 ± 273)μg/L,(1.14 ± 1.02) mg/L vs.(1.55±1.38)mg/L,(0.30±0.12)μg/L vs.(0.41±0.10)μg/L,all P＜0.05],and the decrements were much more in the observation group than in the control group (P＜0.05).The annual accumulated frequence and duration of hospitalization were less in the observation group than in the control group[(0.8±0.6)times vs.(1.8±1.0) times,(10.2±5.8)d vs.(16.5±7.2)d,P＜0.05].The maintenance dose of tolasemide was lower in the observation group than in the control group [(15.2±8.4)mg vs.(20.6±10.8)mg,P＜0.05].Conclusions Sacubitril/valsartan therapy is safe and effective and it can reduce hs-CRP and sST2 levels and improve the ventricular remodeling in HFrEF patients of HYHA Ⅳ.

Predictive value of serum procalcitonin and hypersensitive C-reactive protein levels in patients with acute cerebral infarction complicated with infection / 中华危重病急救医学

To analyze the changes of early procalcitonin (PCT) and hypersensitive C-reactive protein (hs-CRP) in patients with acute cerebral infarction, and to explore the predictive value of both for acute cerebral infarction with infection. Methods 206 acute cerebral infarction patients admitted to the department of neurology of Feicheng Mining Center Hospital from May 2014 to May 2019 were enrolled. Clinical data of patients and serum PCT and hs-CRP levels at 24, 48 and 72 hours after onset were collected. Patients were divided into infected group (n = 69) and non-infected group (n = 137) according to whether infection occurred within 5 days after onset. And 60 healthy people in the same period were selected as the healthy control group. The trends of serum PCT and hs-CRP levels in each group were analyzed. The receiver operating characteristic (ROC) curve was used to analyze the values of serum PCT and hs-CRP levels in identifying acute cerebral infarction with infection. Results The serum level of PCT at 24, 48 and 72 hours in the infected group and the non-infected group were significantly higher than those in the healthy control group, and the serum level of PCT at 48 hours and 72 hours in the infected group were significantly higher than those in the non-infected group (μg/L: 0.28±0.08 vs. 0.19±0.03, 0.31±0.07 vs. 0.15±0.06, both P < 0.05). Compared with 24 hours, the serum PCT level in the infected group at 48 hours and 72 hours were significantly increased, but decreased in the non-infected group. The serum hs-CRP level in the infected group at 24, 48 and 72 hours were significantly higher than those in the non-infected group and the healthy control group (mg/L: 5.86±1.73 vs. 5.45±1.08, 5.25±1.33; 8.01±2.41 vs. 5.67±2.13, 5.25±1.33; 14.25±2.19 vs. 12.30±1.87, 5.25±1.33; all P < 0.05). And the serum hs-CRP level in the non-infected group at 72 hours was significantly higher than that in the healthy control group. Compared with 24 hours, the serum hs-CRP level in the infected group and non-infected group at 48 hours and 72 hours were significantly increased. It was shown by ROC curve analysis that serum PCT and hs-CRP levels at 24 hours had no predictive value for infection in patients with acute cerebral infarction [area under ROC curve (AUC) was 0.440, 0.576 respectively, both P > 0.05]. At 48 hours, the AUC of serum PCT in diagnosis of acute cerebral infarction with infection was 0.850 [95% confidence interval (95%CI) = 0.784-0.916], the sensitivity and specificity were 66.7% and 97.8% when the cut-off of PCT was 0.25 μg/L; the AUC of serum hs-CRP was 0.759 (95%CI = 0.689-0.830), the sensitivity and specificity were 66.7% and 76.6% when the cut-off of hs-CRP was 6.80 mg/L; the AUC of PCT combined with hs-CRP was 0.911 (95%CI = 0.859-0.964), the sensitivity was 90.5%, the specificity was 86.9%. At 72 hours, the AUC of serum PCT in diagnosis of acute cerebral infarction with infection was 0.952 (95%CI = 0.916-0.989), the sensitivity and specificity were 89.9% and 93.4% when the cut-off of PCT was 0.23 μg/L; the AUC of serum hs-CRP was 0.753 (95%CI = 0.678-0.828), the sensitivity and specificity were 60.9% and 83.2% when the cut-off of hs-CRP was 14.01 mg/L; the AUC of PCT combined with hs-CRP was 0.954 (95%CI = 0.918-0.991), the sensitivity was 97.1%, and the specificity was 89.8%. The results showed that the diagnostic value of serum PCT at 48 hours and 72 hours were higher than those of hs-CRP, and the predictive value of PCT combined with hs-CRP was higher than those of single index. Conclusion Acute cerebral infarction itself has an effect on serum PCT level; serum PCT level above 0.23 μg/L at 72 hours after onset and reference to serum hs-CRP level have a high predictive value for the diagnosis of infection in patients with acute cerebral infarction.

Correlations of expressions of peripheral blood regulatory T cells and related inflammatory factors with TOAST subtypes and infection risk in patients with acute cerebral infarction / 中华神经医学杂志

Objective To explore the differences of degrees of immune inflammatory response in patients with different TOAST subtypes of acute cerebral infarction and their relations with infection risk after cerebral infarction.MethodsOne hundred and fifty-four patients with acute cerebral infarction who were free of detectable infection on admission, admitted to our hospital from October 2017 to June 2018, were recruited as patient group; according to TOAST subtypes, these patients were divided into large-artery atherosclerosis group (LAA,n=72), cardioembolic group (CE,n=38), and small-artery occlusion group (SAO,n=44); 45 healthy subjects enrolled at the same period were selected as control group. Fasting blood samples were taken on the next day of admission or during physical examination. Treg％ (percentage of CD4+CD25+CD127[low] regulatory T cells [Treg] in CD4+ lymphocytes) was measured by flow cytometry. Interleukin (IL)-6, IL-10, and hypersensitive C-reactive protein (hsCRP) levels were measured by ELISA or Turbidimetric inhibition immuno assay. Spearman correlation analysis was performed to investigate the relations of Treg％ and related inflammatory factors with TOAST subtypes of acute cerebral infarction and post-stroke infection risk. Receiver operating characteristic (ROC) curve was used to analyze the predictive values of Treg％ and inflammatory factors in post-stroke infection. Univariate Logistic regression analysis and multivariate Logistic regression analysis were used to screen the risk factors of infection after cerebral infarction.Results(1) Treg％ in LAA group was significantly lower than that in control group (P<0.05), and Treg％ in CE group was statistically higher than that in control group (P<0.05); patients in the LAA and CE groups had significantly higher IL-6 and hsCRP levels as compared with those in the control group (P<0.05); patients in the LAA, CE and SAO groups had significantly lower IL-10 level than those in the control group (P<0.05); patients in the LAA and SAO groups had significantly decreased IL-6 and IL-10 levels as compared with those in the CE group (P<0.05); patients in the SAO group had significantly lower hsCRP level as compared with those in the CE group (P<0.05). Spearman correlation analysis showed that Treg％ was negatively correlated with LAA (rs=-0.488,P=0.000) and positively correlated with CE and SAO (rs=0.355,P=0.000;rs=0.200,P= 0.013); the levels of IL-6, IL-10 and hsCRP were positively correlated with CE (rs=0.578,P=0.000;rs= 0.508,P=0.000;rs=0.299,P=0.015), and negatively correlated with SAO (rs=-0.404,P=0.001;rs=0.394, P=0.001;rs=0.308,P=0.012). (2) There were 36 patients who developed infection associated with cerebral infarction in the patient group; as compared with those in the non-infection group, Treg％, IL-6, IL-10 and hsCRP levels in the infection group were significantly increased (P<0.05); Spearman correlation analysis showed that Treg％ and hsCRP were positively correlated with infection after cerebral infarction (rs= 0.305,P= 0.007;rs=0.653,P=0.000). The area under the curve of hsCRP for prediction of post-stroke infection was 0.943 (95％ confidence interval [CI]: 0.895-0.992,P=0.000), that of Treg％ was 0.707 (95％CI: 0.548-0.866,P=0.008), and that of combination of hsCRP and Treg％ was 0.958 (95％CI: 0.918-0.998,P=0.000). (3) Multivariate Logistic regression analysis showed that hsCRP was an independent risk factor for post-infarction infection (P<0.05).ConclusionsThere are differences in the degrees of immune inflammatory response among patients with different TOAST subtypes of acute cerebral infarction. Treg％ and hsCRP can be used as early warning markers of infection after cerebral infarction.

Objective To observe clinical efficacy of atorvastatin combined with clopidogrel for treatment of patients with unstable angina and its influences on hypersensitive C-reactive protein (hs-CRP) and prognosis of such patients. Methods Data of four hundred and thirty patients with unstable angina pectoris admitted to Tangshan Worker's Hospital from January 2013 to December 2017 were collected, and according to difference in drug application, they were divided into control group and observation group, with 215 patients in each group. Both groups were treated with routine western therapy; the patients in the control group were subjected to enteric-coated aspirin (the initial dose was 300 mg and the maintenance dose 100 mg/d) atorvastatin therapy (20 mg orally taken, once a day) on the basis of conventional therapy, subcutaneous injection of 4.1 kU low molecular weight heparin calcium every 12 hours once time for 7 days; the patients in the observation group were subjected toatorvastatin therapy (similar dosage used in the control group) and clopidogrel therapy (the initial dose was 30 mg and the maintenance dose was 75 mg/d) on the basis of conventional treatment. After both groups were treated for 6 months, their clinical efficacies were evaluated. The differences of cholesterol (TC), triacylglycerol (TG), hs-CRP were compared before and after treatment between the two groups, and the clinical curative effect, and drug adverse reaction were observed in the two groups. Results After treatment, the total effective rate of the observation group was significantly higher than that of the control group [92.56% (199/215) vs. 73.48% (158/215), P < 0.05, P < 0.05]. After treatment, the levels of TC, TG and hs-CRP in the two groups were lower than those before treatment, and the above indexes in the observation group were significantly lower than those in the control group [TC (mmol/L): 2.28±0.29 vs. 3.81±1.33, TG (mmol/L): 4.35±0.32 vs. 7.77±0.24, hs-CRP (mg/L): 5.41±2.26 vs. 7.15±3.22, all P < 0.05].There was no significant difference in the incidence of adverse reactions between the observation group and the control group [7.91% (17/215) vs. 10.25% (22/215), P > 0.05]. Conclusion Atorvastatin combined with clopidogrel for treatment of unstable angina pectoris can effectively lower the level of hs-CRP,and it has important significance for improving the prognosis of such patients.

Effects of the polymorphsim 5-HTTLPR on the hypersensitive C-reactive protein in patients with de-pression / 中华行为医学与脑科学杂志

Objective To explore the influences of serotonin transporter promoter region (5-HTTLPR)polymorphism on hypersensitive C-reactive protein(hs-CRP)in patients with depression. Method 5-HTTLPR polymorphism was detected by polymerase chain reactive-restriction fragment length polymorphism(PCR-RFLP)in 103 patients with depression and 103 healthy controls.The severity of depres-sion was evaluated by Hamilton Depression Scale(HAMD).The hs-CRP level was tested by immunofluores-cence.The influence of different genotypes on hs-CRP and the interaction of genotype and hs-CRP on the pathogenesis of depression were analyzed. Results The frequency of genotype and allele in 5-HTTLPR was no statistical significant(P=0.81,0.121)among the three groups.There were statistically significant differ-ences in hs-CRP concentration(P=0.007)among the three genotypes of the study group,and the concentra-tion of hs-CRP in SS genotype((8.1±2.7)mg/L)was significantly higher than that in LS((4.9±1.8)mg/L) and LL genotype((5.2±1.3)mg/L)(P=0.002,0.001).The retardation factor in patients were significantly differences in different genotypes(F=4.637,P=0.033).SS genotype(9.3±3.1)was significantly higher than LL(6.1±2.7)and LS genotypes(5.8±2.1)in retardation factor(P=0.008,0.007).Logistic regression analy-sis showed that SS genotype was associated with hs-CRP.The interactive effect was positive related to the morbidity of depression.The correlation of interaction between SS genotype and hs-CRP was greater than LL/LS(OR=1.890,95%CI=1.011-3.396). Conclusion SS genotype of 5-HTTLPR has strengthen effect on hs-CRP.The interaction of genotype and hs-CRP affects the onset of depression.The interaction of SS geno-type and hs-CRP is more likely to effect the onset of depression.
