RESUMEN
ObjectiveTo investigate the effects of acupuncture combined with Du-Moxibustion (ADM) on peripheral blood cell count and levels of immune factors in patients with occupational chronic benzene poisoning. Methods A total of 70 patients with occupational chronic benzene poisoning (leukopenia and neutropenia) were selected as the research subjects by judgement sampling method. They were randomly divided into a control group and an ADM group using a random number table method, with 35 cases in each group. Patients in the control group were treated with conventional Western medicine such as leukocyte boosting and symptomatic treatment. While patients in the ADM group were treated with ADM treatment in addition to treatments of the control group, once per week for five consecutive weeks. Peripheral blood samples of patients were collected before and after treatment from both groups, to detect cell counts and serum levels of immune factors. Results The white blood cell count, red blood cell count, absolute lymphocyte count, absolute neutrophil count, platelet count, and levels of hemoglobin, immunoglobulins (Ig) A, IgM, IgG, complement C3 and complement C4 of patients in both groups improved after treatment compared with those before treatment (all P<0.05). The white blood cell count, levels of IgA, IgM, IgG, complement C3 and complement C4 of patients in the ADM group were higher than those in the control group after treatment (all P<0.05). Conclusion ADM treatment can increase peripheral blood white blood cells and serum levels of immune factor in patients with occupational chronic benzene poisoning (leukopenia, neutropenia), which helps improve patient recovery and can be promoted clinically.
RESUMEN
Objective To evaluate the performance of two molecular point-of-care testing(POCT)prod-ucts in the diagnosis of influenza A virus(Flu A)and influenza B virus(Flu B)of clinical samples,and pre-liminarily evaluate the clinical diagnostic value of the changes of infection-related indicators in peripheral blood.Methods A total of 491 oropharyngeal swabs from patients with influenza-like symptoms who were treated in the hospital were recruited into this study from November 1,2019 to June 30,2023.These swabs were collected using reverse transcription real-time quantitative fluorescent polymerase chain reaction(RT-qPCR),and two POCT molecular products,XpertTM Xpress Flu/RSV and EasyNAT? Flu Assay,respectively.The diagnostic performance of two POCT molecular products was analyzed using RT-qPCR reaction as a standard.According to the results of RT-qPCR method,the subjects were divided into Flu A positive group,Flu B positive group and negative group(both Flu A and Flu B were negative).The levels of indicators in pe-ripheral blood of the three groups were compared to evaluate the value of these indicators in the clinical diag-nosis of Flu A and Flu B.Results Among the 491 patient specimens,the XpertTM Xpress Flu/RSV assay showed the sensitivity for Flu A was 96.88%,and the specificity was 99.75%,and the sensitivity for Flu B was 100.00%,and the specificity was 100.00%.EasyNAT? Flu Assay assay showed the sensitivity for Flu A was 94.79%,and the specificity was 96.81%,and the sensitivity for Flu B was 100.00%,and the specificity was 100.00%.And two POCT molecular methods performed well consistency(Kappa value was 0.974).There was no significant difference in the levels of C-reactive protein and serum amyloid A among the negative group,Flu A positive group,and Flu B positive group(P>0.05).But the levels of white blood cell count in the negative group were higher than those in the Flu A positive group and Flu B positive group(P<0.01).Conclusion In this paper,two typical molecular POCT products are studied.Their sensitivity and specificity are highly consistent with the results of RT-qPCR.Molecular POCT products have the advantages of flexibil-ity and rapidity,which are of great value for the improvement of clinical diagnosis and treatment.Molecular detection combined with peripheral blood infection related indicators is helpful for the early diagnosis of influ-enza virus infectious diseases.
RESUMEN
Objective To explore the relationship between inflammatory indexes,fasting plasma glucose(FPG),blood lipid in early pregnancy(6 to 13W+6D)and gestational diabetes mellitus(GDM).Methods Ninety-eight pregnant women in early pregnancy who underwent prenatal examinations at the First Affiliated Hospital of Xinxiang Medical University from No-vember 2020 to October 2021 were selected as the research subjects.These pregnant women were divided into the GDM group(n=35)and normal glucose tolerance(NGT)group(n=63)according to the oral glucose tolerance test results in the second trimester of pregnancy(24-28W).All subjects kept fasting for at least 8 hours at 6 to 13W+6D of pregnancy,and the blood was collected from the median cubital vein on the morning of the second day,the white blood cell(WBC)count,neutrophil count(NC),lymphocyte count(LC),monocyte count(MC),FPG,and serum total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C)levels were measured.The differences in various indicators of pregnant women between the GDM group and NGT group were compared.The joint predictive factors for GDM was obtained by multivariable logistic regression model,and the independent risk factors of GDM were analyzed,and the efficiency of each risk factor in predicting the occurrence of GDM was evaluated by the receiver operating characteristic(ROC)curve.Results The FPG,WBC,LC,TC,TG and LDL-C levels of pregnant women in the GDM group were significantly higher than those in the NGT group in early pregnancy(P＜0.05);there was no significant difference in the NC,MC and HDL-C levels of pregnant women between the two groups(P＞0.05).Logistic regression model analysis results showed that the increase of FPG,WBC,TC and TG were independent risk factors affecting the occurrence of GDM(P＜0.05).Taking FPG=4.80 mmol·L-1,WBC=9.35 × 109 L-1,TC=4.05 mmol·L-1 and TG=1.61 mmol·L-1 as cut-off values,the area under the curve(AUC)of above indexes in predicting GDM were 0.779,0.721,0.685 and 0.762,respectively;the sensitivity was 0.886,0.514,0.857 and 0.543,respectively;the specificity was 0.587,0.857,0.524 and 0.873,respectively.The AUC of the combined prediction of FPG,WBC,TC and TG for GDM was 0.876,with a sensitivity of 0.857 and a specificity of 0.810.The AUC of the combined prediction of FPG,WBC,TC and TG for GDM was significantly higher than that of FPG,WBC,TC and TG in early pregnancy alone for GDM.Conclusion Elevated levels of FPG,WBC,TC and TG in early pregnancy(6 to 13W+6D)are independent risk factors for GDM,and they can be used as clinical indicators for the early prediction of GDM.The combination of the four indicators has better predictive value for GDM.

RESUMEN
Objective:To investigate the relationship between white blood cells, neutrophil-lymphocyte ratio(NLR), platelet-lymphocyte ratio(PLR) and monocyte-lymphocyte ratio(MLR) with patients suffering from first episode depression.Methods:This retrospective study was conducted among inpatients of Hebei General Hospital from January 2021 to December 2021.Ultimately, 193 patients with first-episode depression were enrolled.According to the score of Hamilton depression scale-24 (HAMD-24), the patients were divided into mild-moderate depression group(20≤HAMD-24<35 score, n=98) and severe depression group (HAMD-24 score ≥35, n=95). White blood cells and the counts of each cell subtype were detected and the NLR, MLR and PLR were calculated.SPSS 25.0 statistical software was used to analyze the data.Mann-Whitney U test was used to compare differences in the two groups and Binary Logistic regression analyses were performed to recognize the predictive factors of the severity of first episode depression. Results:(1) The white blood cells and NLR in the severe depression group were significantly higher than those in the mild-moderate depression group (white blood cells: 5.77(2.05)×10 9/L vs 5.11(1.31)×10 9/L; NLR: 1.86 (1.04) vs 1.57(0.55), P<0.05). There were no significant differences in PLR and MLR between the two groups ( P>0.05). (2)Multiple regression analysis of NLR, white blood cells and HAMD-24 score showed that there were significant differences in the effect of different white blood cells and NLR levels on HAMD-24 score( B=1.398, P=0.003; B=2.624, P=0.001). (3)Binary Logistic regression revealed that white blood cell count and NLR were risk factors for the severity of depression patients( OR were 1.612 and 2.336, respectively, P<0.05). Conclusion:The results suggest that white blood cells and NLR may be relate with the severity of first episode depression.
RESUMEN
Objective:To investigate the risk factors for infection after cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS+ HIPEC), and observe the infection in patients who underwent this combined procedure, to explore the predictive value of postoperative white blood cell count (WBC), C-reactive protein (CRP), procalcitonin (PCT) and systemic immune inflammation index (SII) for postoperative infection.Methods:Clinical data of 106 patients who underwent CRS + HIPEC in the Fifth Medical Clinical College of Shanxi Medical University between July 2019 and July 2022 were retrospectively analyzed. These patients, including 61 males and 45 females, (58.93±10.65) years old, were divided into the infection group ( n=19) and the non-infection group ( n=87) according to the presence of postoperative infection. Risk factors were analyzed for patients in the infection group, and postoperative WBC, CRP, PCT and SII were determined for patients in both groups to determine their prognostic values. Risk factors for postoperative secondary infection in patients with CRS+ HIPEC were analyzed using univariate and multivariate logistic regression. Predictive values of WBC, PCT, CRP and SII for postoperative infection were evaluated by receiver operating characteristic (ROC) curve, and the optimal cutoff values of these variables were determined by Youden index and evaluated using sensitivity, specificity, positive predictive value, and negative predictive value as evaluation indexes. Nomogram prediction model was constructed using R software and samples were included in this model to calculate the total score of these patients. ROC curve analysis and calibration curve verification were then performed. Results:Univariate analysis showed significant differences in age, body mass index (BMI), postoperative fistulization, preoperative serum albumin, combined multiple organ resection, and operation duration between the infection and non-infection groups ( P<0.05). WBC, CRP, PCT and SII were compared between the infection group and the non-infection group on were compared on postoperative days 1, 3, 5 and 7, and the ROC curves were plotted accordingly. The area under the ROC curve (AUC) of the WBC, CRP, PCT and SII on postoperative Days 1, 3, 5 and 7, and their 95% CI, sensitivities and specificities were compared. It was found that the predictive values of the 5th postoperative day WBC and PCT, and the 7th postoperative day CRP were superior to those determined on other postoperative days, and SII was not significant in predicting postoperative secondary infection in patients who underwent CRS+ HIPEC. The cut-off values of the 5th postoperative day WBC and PCT and the 7th postoperative day CRP were 7.7×10 9/L, 2.068 ng/mL and 76.43 mg/L, respectively, and AUCs and their 95% CI were 0.754 and (0.625, 0.883), 0.830 and (0.717, 0.943), 0.715 and (0.584, 0.846), respectively, with sensitivities of 78.9%, 68.4% and 63.2%, respectively, and specificities of 70.1%, 96.5% and 75.9%, respectively. The predictive values of PCT on postoperative days 1, 3, 5 and 7 were superior to those of WBC, CRP and SII determined on each corresponding day. The cut-off values of the 5th postoperative day WBC and PCT and the 7th postoperative day CRP were used as the classification thresholds, and the results after classification as well as significant variables in univariate analysis, including age, BMI≥25 kg/m 2, postoperative fistulization, preoperative serum albumin≥35 g/L, number of organs resected and operation duration were included in multivariate logistic regression analysis. The results showed that BMI≥25 kg/m 2, combined multiple organ resection, WBC and PCT on the 5th postoperative day and, CRP on the 7th postoperative day were independent risk factors for secondary infection ( P<0.05). A Nomogram prediction model was then constructed. Points indicated the scores for each variable, and the corresponding scores were 70 when BMI was ≥25 kg/m 2, 80 when multiple organ resection was combined, 100 when the 5th postoperative day WBC was ≥7.7×10 9/L, and 79 when the 7th postoperative day CRP was ≥76.3. The sum of the scores for all variable was calculated and used as total score for the patient. The total score obtained from the Nomogram prediction model was used for ROC curve analysis and calibration curve verification. The ROC curve analysis showed that the AUC was 0.966, with a sensitivity of 0.895 and specificity of 0.966, indicating an excellent discriminative power of the model. The significance level of the calibration curve was 0.05, and the absolute error between the predicted and actual incidences of postoperative infection after CRS+ HIPEC was 0.038. Conclusions:The incidence of secondary infection after CRS+ HIPEC is related to factors such as BMI and combined multiple organ resection. Inflammation markers in peripheral blood, including PCT, CRP and WBC, can serve as predictors for postoperative secondary infection in patients with CRS+ HIPEC, and the fifth postoperative day WBC and PCT and the seventh postoperative day CRP among others have the highest diagnostic values for postoperative infections. In addition, the predictive value of combined diagnosis is superior to that of individual testing.
RESUMEN
Objective To explore the correlation between CAE and the ratio of white blood cell count to mean platelet volume ratio(WMR)in elderly patients.Methods A retrospective analysis was conducted on 238 patients who underwent coronary angiography(CAG)between January 2018 and January 2023 in Department of Cardiology of Tianjin First Central Hospital.According to the results of CAG and patient's age,they were divided into in elderly CAE group(age ≥65 years,100 cases)and non-elderly CAE group(age＜65 years,138 cases).Another 127 age-matched elderly individuals with normal coronary artery(age ≥65 years)served as normal con-trol group.The WMR levels were measured in all participants.Results The elderly CAE group had significantly higher WMR than the non-elderly CAE group and the normal control group(745.50±237.46 vs 672.43±194.52 and 610.11±144.22,P=0.000).Spearman correlation analy-sis showed that WMR was positively correlated with platelet count,neutrophil count and high-sensitivity C-reactive protein level(r=0.380,P=0.000;r=0.819,P=0.000;r=0.283,P=0.000).Multiple logistic analysis indicated that readmission,male,TC and WMR were significantly associated with CAE in elderly patients.ROC curve analysis revealed that the value of WMR to distinguish the presence of CAE in elderly patients was 0.604(95％CI:0.531-0.677,P=0.006).Conclusion Elevated WMR might be a cost-effective monitor in elderly CAE patients.
RESUMEN
@#Objective This study aims to explore the correlation between white blood cell count (WBC),absolute neutrophil count (ANC),relative neutrophil count (RNC) and neurological impairment,poor prognosis at discharge and 90 days after onset.Methods This study was a retrospective study,including patients aged 18 to 45 years old with first ischemic stroke within 72 hours.NIHSS score at discharge,mRS score at discharge and 90 days were used as outcome.Multivariate logistic regression was used to analyze the relationship between WBC quartile,ANC,RNC and neurological deficit (NIHSS score>4) and poor prognosis (mRS score 2~5).Results WBC>7.82×10 9/L was independently associated with moderate and severe neurological deficit at discharge and poor prognosis at 90 days.The ANC was only associated with poor prognosis at 90 days,independently.The RNC was an independent risk factor for moderate and severe neurological impairment at discharge,poor prognosis at discharge and 90 days.Conclusion WBC>7.82×10-9/L is an independent risk factor for moderate and severe neurological impairment at discharge and poor prognosis at 90 days in young patients with stroke.The increase of RNC,which is independently related to moderate and severe neurological impairment and poor prognosis,is more indicative than ANC for poor prognosis in young patients with stroke.
RESUMEN
Objective:To investigate the clinical situation of 201 emergency adult sudden death patients, and analyze the influence of white blood cell count and arterial blood lactate level on prognosis.Methods:The clinical data of 201 patients diagnosed with sudden death in the emergency department of Medical College of Cangzhou people's Hospital from January 2017 to January 2021 were retrospectively analyzed. The gender, age, disease composition and etiology of the patients were statistically analyzed. The independent sample t-test was used to compare the measurement data with normal distribution, the χ 2 test or Fisher exact probability method was used to compare the counting data between groups, and the logistic regression model was used to screen the risk factors of emergency death, and the impact of white blood cell count and arterial blood lactate level on the prognosis was analyzed. Results:After active rescue, 11.44% (23/201) of the patients were successfully rescued, and 88.56% (178/201) of the patients were ineffective; ≥46-≤65 years old was the age group with high incidence of sudden death (55.22%(111/201)). The proportion of male (43.28% (87/201), 23.38% (42/201)) in the age group of ≥46-≤65 years old and the age group over 65 years old were higher than that of female (11.94% (24/201), 14.43% (29/201)), with a statistically significant difference (χ 2=4.801, 9.209; P=0.028, 0.002). In the past history of sudden death patients, the proportion of cardiovascular disease (53.23% (107/201)) was the highest; the proportion of patients may have inducements before sudden death was 74.13% (149/201), the proportion of patients have premonitory symptoms before sudden death was 67.66% (136/201), and sudden cardiac death was the first cause. Logistic regression analysis showed that white blood cell count ( OR=4.442,95% CI: 1.898-10.395), arterial blood lactic acid concentration ( OR=4.272,95% CI: 2.024-9.016), and albumin concentration ( OR=2.657,95% CI: 1.302-5.422) were independent risk factors affecting emergency sudden death patients ( P values were 0.001, <0.001, 0.007, respectively). Conclusions:There are some differences in gender, age and past history of adult sudden death patients. Most of them have premonitory symptoms and inducements. Sudden cardiac death is the primary cause. The increases of white blood cell count and lactic acid level, the decrease of albumin level are the risk factors of sudden death.

Among the three indicators, the diagnostic value of neutrophil CD64 index was much higher. When the optimal cut-off value was 4.32, the sensitivity and specificity were 83.6% and 88.7%, respectively, which were higher than the sensitivity (75.1%, 76.3%) and specificity (87.2%, 82.5%) of CRP and PCT. Conclusion:Neutrophil CD64 index is a valuable biomarker for the diagnosis of sepsis in ICU.
RESUMEN
@#Objective To investigate the risk factors for early in-hospital death in patients with acute Stanford type A aortic dissection and emergency surgical treatment. Methods We retrospectively analyzed the clinical data of 189 patients with acute Stanford type A aortic dissection who underwent surgery in the First Affiliated Hospital of Xinjiang Medical University between January 2017 and January 2020. There were 160 males and 29 females with an average age of 46.35±9.17 years. All patients underwent surgical treatment within 24 hours. The patients were divided into a survival group (n=160) and a death group (n=29) according to their outcome (survival or death) during hospitalization in our hospital. Perioperative clinical data were analyzed and compared between the two groups. Results The overall in-hospital mortality was 15.34% (29/189). There was a statistical difference between the two groups in white blood cell count, blood glucose, aspartate aminotransferase (AST), bilirubin, creatinine, operative method, operation time, aortic occlusion time, or cardiopulmonary bypass time (P<0.05). Multivariate regression identified white blood cell count [OR=1.142, 95%CI (1.008, 1.293)], bilirubin [OR=0.906, 95%CI (0.833, 0.985)], creatinine [OR=1.009, 95%CI (1.000, 1.017)], cardiopulmonary bypass time [OR=1.013, 95%CI (1.003, 1.024)] as postoperative risk factors for early in-hospital death in the patients undergoing acute Stanford type A aortic dissection surgery (P<0.05). Conclusion Our study demonstrated that white blood cell, bilirubin, creatinine and cardiopulmonary bypass time are independent risk factors for in-hospital death after acute Stanford type A aortic dissection surgery.
RESUMEN
BACKGROUND: Obtaining synovial fluid for diagnostic test of periprosthetic joint infection is invasive and painful to patients. Platelet count is a regular blood test which has been used as a possible predictor of several infectious diseases. Presumably, it could be one of the indicators of periprosthetic joint infection. OBJECTIVE: To identify the accuracies of platelet combined with white blood cell, erythrocyte sedimentation rate or C-reactive protein in the diagnosis of periprosthetic joint infection. METHODS: Patients undergoing revision arthroplasty from March 2013 to December 2018 in the First Affiliated Hospital of Guangzhou University of Chinese Medicine were retrospectively enrolled. A diagnosis of periprosthetic joint infection was confirmed in 77 patients according to the criterions from the Musculoskeletal Infection Society; the remaining 137 patients were confirmed as aseptic cases. White blood cell, erythrocyte sedimentation rate, or C-reactive protein and platelet count were compared between the two groups. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated. RESULTS AND CONCLUSION: The platelet values were significantly increased in periprosthetic joint infection cases. Sensitivity and specificity of the platelet for periprosthetic joint infection were 64.94% and 86.13%, respectively. Platelet demonstrated a higher accuracy when compared to erythrocyte sedimentation rate and C-reactive protein. In such cases, the platelet shows a certain reference value in confirming the diagnosis of periprosthetic joint infection. Platelet was enough used as adjunct diagnostic tool in patients suspected with periprosthetic joint infection.

RESUMEN
Background@#Establishment of quantitative reference intervals of white blood cells and its subpopulations using a high accuracy analytic system is essential for clinical medicine, public health, and anthropology. We are unable to identify peer-reviewed literature sources describing white blood cell counts and their subpopulations using monoclonal antibodies to specific surface antigens in healthy Mongolians. This study aimed to measure the counts of white blood cells and their subpopulations in healthy Mongolians using flowcytometry. @*Materials and Methods@#The absolute number (cell/L) of leukocytes (CD45+), granulocytes, monocytes and lymphocytes were measured by Magnetic Activated Cell Sorting Assay (MACSQuant Analyzer 10) in 287 blood donors (158 males and 129 females) 17-64 years of age (mean age 33.1±12.4). Peripheral blood samples were collected at the time of blood donation at the National Center for Transfusion Medicine.@*Results@#The mean values of leukocytes and granulocytes were lower in donors over 30 years of age (ANOVA: F=4.408, p=0.002 and F=5.685, p=0.001) and regression analysis demonstrated indirect correlation between counts of these cells and age of donors (r= - 0.198, p=0.001 and r=-0.221, p=0.001, respectively). Gender-related differences in white blood cell counts were not found.</br> Mean value of lymphocyte count in donors investigated in spring (May and March, n = 87; 2224.6±775.3) was significantly higher than those in winter (December – February, n=180; 1613.2±454.3, p=0.001) and autumn (October, n=20; 1576.1±438.6, p= 0.001). </br> Comparing of our findings with the data from available literature shown that healthy Mongolians have lower leukocyte count compared with Koreans, Chinese Han population and lower mean value of lymphocyte count comparing with Korean, Chinese Han population, and Arabian (Saudi Arabia) populations.
RESUMEN
Background: Anemia is characterized by reduction in number of red blood cells or their oxygen carrying capacity to meet physiologic needs. It varies by age, sex, altitude, smoking, and pregnancy status. India has the uppermost prevalence (39.86%) of anemia among the 16MM i.e. 16 major pharmaceutical markets such as United States of America, France, Germany, Italy, Spain, United Kingdom, Japan, Australia, Brazil, Canada, China, India, Mexico, Russia, South Africa, and South Korea.4 In India, a survey (2016) reported that the prevalence of anemia among women of reproductive age was 51.40%; pre-school children was 57.30%, and among non-pregnant women was 51.50%. Methods: The duration of study was over a period of one year. Study Area:-This study was conducted in Department of pediatrics in K M Medical College & Hospital, Mathura.100 total numbers of cases were included in this study. Results: The prevalence of anemia was moderate which were in 48 % cases followed by 24% mild,19% not anemic & 9% severe. Conclusions: This study concludes that the main reason behind this high percentage of children with anemia in this age group is prolonged breast feeding, inadequate weaning practices.

Objective: To investigate the distribution of JAK2V617F mutation in the patients with myeloproliferative neoplasms (MPN), to explore the association between JAK2V617F mutation and the clinical features of MPN, and to clarify its clinical significance in the diagnosis and treatment of the MPN patients. Methods: A total of 170 patients with MPN were selected as the subjects and divided into true polycythemia (PV) group (n=68), primary thrombocytopenia (ET) group (n=88) and primary myelofibrosis (PMF) group (n=14). The JAK2V617F mutations in 170 patients with MPN were detected by allele-specific PCR (AS-PCR). The differences in gender, age, white blood cell count, hemoglobin, platelet count, prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer, whether complicated with splenomegaly and thromboembolism of the JAK2V617F mutant-type and wild-type patients in each group were analyzed. Results: The total mutation rate of JAK2V617F mutation in 170 patients with MPN was 68. 2% (116/170), and the mutation rates in PV, ET, and PMF groups were 72. 1% (49/68), 68. 1% (60/88), and 50. 0% (7/14), respectively. The JAK2V617F mutation rate in PV group was higher than those in the other two groups, but there were no statistical differences (P = 0. 281). Compared with wild type group, the age of onset, the white blood cell and platelet counts of the PV patients with JAK2V617F mutation were significantly increased (P
RESUMEN
To evaluate the prognostic value of early white blood cell count (WBC) in patient of acute paraquat poisoning. Methods The literatures about the studies on early WBC and prognosis after paraquat poisoning published in journals at home and abroad were searched. The Chinese literature database contained CNKI, VIP, Wanfang Database, and China Biomedicine Database (CBM), and the journals were limited to the core journals. The foreign language database included PubMed, Embase and Cochrane library clinical controlled trial database. The retrieval date was from the initial publication to April 22nd in 2019, without the limitation of languages. Two researchers independently extracted literature information, and the Newcastle-Ottawa Scale (NOS) was used to evaluate literature quality. The odds ratio (OR), sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR) and the area under the summary receiver operating characteristic (SROC) were combined and analyzed through the Stata 15.0 software to evaluate the predictive value of early WBC after acute paraquat poisoning. Publication bias was analyzed by Deeks funnel graph. Results There were 7 retrospective studies and 1 prospective study in a total of 980 paraquat poisoning patients, 5 of them were English literatures, the others were Chinese literatures. There was no heterogeneity among the studies (I 2 = 43.5%, P > 0.05). The OR and its 95% confidence interval (95%CI) of the literature was combined through the fixed effect model. The Meta-analysis results were statistically significant (OR = 18.63, 95%CI = 13.63-25.48, P < 0.001), suggesting that the WBC was significantly correlated with the mortality of patients. The combined sensitivity, specificity, PLR, NLR and DOR were 0.75 (95%CI = 0.66-0.82), 0.85 (95%CI = 0.80-0.90), 5.14 (95%CI = 3.86-6.86), 0.29 (95%CI = 0.22-0.39), 17.53 (95%CI = 12.23-25.13) respectively, and the area under the SROC of the WBC was 0.88 (95%CI = 0.85-0.91). Deeks funnel plot was symmetrical (P = 0.21), and there was no obvious publication bias. Conclusion The early WBC has a certain predictive value for the prognosis of acute paraquat poisoning patients.
RESUMEN
Objective: To clarify the antitussive, expectorant, antipyretic and anti-inflammatory effects of Tanreqing inhalation solution, and provide basis and data support for further research and development of this preparation. Method: The methods of cough induced by ammonia and tracheal phenol red excretion were used to observe the antitussive and expectorant effects of Tanreqing inhalation solution in mice. The fever model of rats was established by intraperitoneal injection of bacterial lipopolysaccharide(LPS) to observe the antipyretic effect of the Tanreqing inhalation solution, the acute pneumonia model of rats was established by atomizing LPS inhalation, and the anti-inflammatory effect of Tanreqing inhalation solution was observed. Result: Tanreqing inhalation solution could reduce the number of coughs in mice induced by ammonia water, increase the amount of phenol red excretion in mouse trachea, decrease the levels of body temperature and its related regulatory factors of prostaglandin E2(PGE2) and cyclic adenosine monophosphate(cAMP) of rats induced by LPS, decrease the white blood cell(WBC) count and the neutrophil ratio(NEUT) in bronchoalveolar lavage fluid(BALF) of rats with LPS-induced acute pneumonia, and reduce the levels of nuclear transcription factor-κB(NF-κB) and interleukin-1β(IL-1β) in lung tissue. Conclusion: Tanreqing inhalation solution has obvious antitussive, expectorant, antipyretic and anti-inflammatory effects, which is worthy of further development and promotion.

@#AIM:To investigate the clinical value of serum amyloid A(SAA)in the diagnosis of infectious endophthalmitis. <p>METHODS:A total of 270 patients admitted to the Eye Hospital of Wenzhou Medical University from June 2016 to March 2019 were collected, including 116 patients with infectious endophthalmitis as the experimental group and 154 non-infectious patients as the control group. The levels of SAA was detected by colloidal gold immunochromatography. Variables were compared and diagnostic value was measured by using receiver operating characteristic(ROC)curve.<p>RESULTS:The median levels of SAA in experimental group and control group were 14.98mg/L and 2.56mg/L, respectively,the difference between the two groups was statistically significant(<i>P</i><0.001); the median levels of CRP and WBC had statistic difference between two groups, respectively(<i>P</i><0.001). The area under the ROC curve of SAA, CRP and WBC for diagnosis of infectious endophthalmitis were 0.772, 0.638 and 0.618 respectively. The optimal cut-off value corresponding to the maximum value of Youden index was 6.975mg/L by SAA, the sensitivity was 63.79% and the specificity was 84.42%.<p>CONCLUSION: SAA combined with CRP and WBC can improve the diagnostic efficacy of infective endophthalmitis. SAA can provide useful reference information for the assistant diagnosis of infectious endophthalmitis, which is worthy of clinical application.
