ABSTRACT
Objective:To study the influence of serum triggering receptor expressed on myeloid cells 1(TREM-1)level on prognosis in elderly patients with sepsis and acute respiratory distress syndrome(ARDS).Methods:A total of 100 elderly patients with sepsis were selected as the research objects.All the patients with sepsis were divided into sepsis ARDS group and sepsis non-ARDS group.General data and TREM-1 level were compared between the two groups.The patients with sepsis ARDS were divided into death group and survival group according to the survival status during the 28-day follow-up.TREM-1 level, acute physiology and chronic health evaluation(APACHE)Ⅱ score and SOFA score were compared between the two groups.The correlation between serum TREM-1 level and procalcitonin(PCT), APACHE Ⅱ score and SOFA score was analyzed.The survival rate of high TREM-1 level group and low TREM-1 level group was compared.Results:The age, white blood cell(WBC), PCT, APACHE Ⅱ score, SOFA score and TREM-1 level of sepsis ARDS patients were significantly higher than those of non-ARDS patients( t=2.722, 6.088, 11.55, 6.889, 4.661, 6.122, all P<0.05). The incidence of sepsis ARDS patients with chronic obstructive pulmonary disease was significantly higher than that of non-ARDS patients( χ2=7.895, P<0.05). Serum TREM-1 level, APACHE Ⅱ score and SOFA score of ARDS patients in death group were significantly higher than those in survival group( t=3.293, 6.173, 4.255, all P<0.05). Serum TREM-1 level was positively correlated with PCT, APACHE Ⅱ score and SOFA score( t=0.553, 0.602, 0.636, P<0.001). The Kaplan-Meier survival curve showed that the survival rate of high TREM-1 level group was significantly lower than that of low TREM-1 level group( χ2=3.999, P=0.036). Cox regression analysis showed that TREM-1 level was a risk factor for the prognosis of ARDS patients with sepsis( HR=1.893, 95% CI: 1.049-3.414). Conclusions:Serum TREM-1 level is significantly increased in elderly patients with sepsis ARDS, which is closely related to the prognosis and can be used as a potential prognostic biomarker.
ABSTRACT
Objective:To compare biomechanical stabilities between screw-plate fixation and non-cannulated screw fixation for Lisfranc ligament injury by a 3-D finite element analysis.Methods:A 3-D model of a healthy foot was developed from computed tomography images. The 1st and the 2nd dorsal tarsometatarsal ligaments and Lisfranc ligament were cut in the 3-D model of a healthy foot to establish a Lisfranc ligament injury model, in which screw-plate fixation (with 2 locking plates and 8 standard screws and one non-cannulated screw) and non-cannulated screw fixation (with 3 non-cannulated screws) for Lisfranc ligament injury were simulated respectively. Finite element analyses were carried out by Abaqus 6.14 software after loads were added in the 3-D models of screw-plate fixation and non-cannulated screw fixation for Lisfranc ligament injury. The overall stress-strain nephogram, the stress distribution and displacement of the foot bone, and the stress distribution on the internal fixation system were compared between the 2 kinds of models.Results:Under the same load, the stress of the whole screw-plate fixation was concentrated on the fixators, and the stress of the non-cannulated screws was also greater than that of the bones. In both models, the strain of the whole foot led to arch collapse, especially in the medial column. The maximum stress on the screw holes in the medial and middle columns in the screw-plate fixation model was 39.91 MPa, smaller than that in the non-cannulated screw fixation model (53.13 MPa). The relative displacement of the first metatarsal joint in the screw-plate fixation model was 8.515 × 10 -1 mm, much greater than that in the non-cannulated screw fixation model (3.893 × 10 -1 mm). Stress concentration was observed in both models. The stress of the screw-plate system was concentrated on the fibular side of the middle section of the plate used to fix the first tarsometatarsal joint, decreasing towards both ends. The maximum stress of the non-cannulated screws was located in the middle of the medial column screw for fixation of the first tarsometatarsal joint, significantly greater than those of the both ends. The maximum stress of the screw-plate system was 239.5 MPa, smaller than that of the non-cannulated screws (256.8 MPa). Conclusions:Non-cannulated screw fixation demonstrates a greater biomechanical stability for Lisfranc ligament injury than screw-plate fixation. However, the former may have a higher risk of screw breakage because it bears a greater stress.
ABSTRACT
Objective:To investigate high mobility group protein 1(HMGB1), tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)levels and their clinical significance in elderly patients with viral pneumonia.Methods:One hundred and sixty elderly patients with viral pneumonia admitted to the Sixth Hospital Affiliated to Anhui Medical University were enrolled as research subjects.In addition, 40 elderly people who underwent regular physical examination were considered as the control group.Patients with viral pneumonia were divided into the low-risk group, middle-risk group and high-risk group according to CURB-65 scores and pneumonia severity index(PSI)scores.HMGB1, TNF-α and IL-6 levels were compared between different groups.The correlations of CURB-65 scores and PSI scores with HMGB1, TNF-α, IL-6 levels were analyzed.Multivariate Logistic regression analysis was used to examine influencing factors for the severity of viral pneumonia in elderly patients.Results:HMGB1, TNF-α and IL-6 levels were higher in research subjects than in the control group.As the severity of viral pneumonia increased, so did HMGB1, TNF-α and IL-6 levels(all P<0.05). HMGB1, TNF-α and IL-6 levels in the severe viral pneumonia group were significantly higher than those in the non-severe viral pneumonia group( P<0.05). HMGB1, TNF-α and IL-6 levels were positively correlated with CURB-65 scores and PSI scores(CURB-65 score: r=0.463, 0.392 and 0.497, P=0.015, 0.003 and 0.025; PSI score: r=0.596, 0.515 and 0.381, P=0.007, 0.011 and 0.009). HMGB1, TNF-α and IL-6 levels were influencing factors for the severity of viral pneumonia in elderly patients( OR=1.344, 1.422 and 1.351, P=0.006, 0.015 and 0.009). Conclusions:HMGB1, TNF-α and IL-6 levels are closely correlated with the severity of viral pneumonia and are helpful for early assessment of viral pneumonia.
ABSTRACT
Objective:To evaluate the accuracy of serum concentration of procalcitonin (PCT) in differential diagnosis of the etiology of bloodstream infections (BSI).Methods:Patients hospitalized in ICU of China-Japan Friendship Hospital from January 2015 to June 2020 with BSI and with PCT test simultaneously when blood drawing for blood culture were enrolled. Sequential Organ Failure Assessment (SOFA) were calculated based on parameters on the day of blood culture. Difference of various indicators among different pathogen infections were compared. Receiver Operating Characteristic (ROC) Curve was used to analyze the value of PCT in differential diagnosis of BSI by different pathogens.Results:Among 1 456 patients with BSI,1 261 (86.6%) patients with monobacterial infection, 80 (5.5%) patients with candidiasis and 115 (7.9%) patients with mixed infection. The 28-day mortality was 24.5% (356/1 456) and the 60-day mortality was 30.6% (446/1456). Mortality of both 28-day and 60-day in the mixed group was significantly higher than that in the bacteriacemia group and candidemia group. PCT levels was significantly higher in patients with bacteremia caused by gram-negative bacteria (GNB) than that in gram-positive bacteria (GPB) infected bacteremia and candidemia {3.4 μg/L[95% confidence interval (95% CI) 0.7-17.0 μg/L] vs 1.3 μg/L (95% CI 0.4-7.3 μg/L); 3.4μg/L (95% CI was 0.7-17.0 μg/L) vs 1.1 μg/L (95% CI was 0.4-3.4 μg/L); P<0.01} . ROC curve analysis showed that: ① the optimal cut-off value of PCT in differential diagnosis of monobacterial bacteremia and candidemia was 7.25 μg/L, with specificity of 90.0% and the area under the ROC curve (AUROC) was 0.612 (95% CI 0.533-0.691). When PCT value was greater than 0.51 μg/L, the sensitivity of diagnostic of bacteremia could reach 73.3%. ② the optimal cut-off value of PCT in differential diagnosis of bacteremia caused by GNB infection and candidemia was 7.32 μg/L, with specificity of 90.0% and AUROC was 0.695 (95% CI 0.614-0.776). When PCT value was greater than 0.51 μg/L, the sensitivity of diagnostic of bacteremia caused by GNB infection was 84.9%.③ the optimal cut-off value of PCT in differential diagnosis of bacteremia caused by GNB and GPB infection was 0.52 μg/L, with sensitivity of 84.9% and AUROC was 0.713 (95% CI 0.672-0.755). When PCT value was greater than 7.36 μg/L, the specificity of diagnostic of bacteremia caused by GNB infection could reach 80.1%. Conclusions:PCT can provide additional information about the possible etiology of patients with BSI, especially as high levels often indicate the possibility of GNB bacteremia.

ABSTRACT
Objective To investigate the potential therapeutic effect of luteolin on sepsis-induced ALI and the underlying mechanisms.Methods Total of 50 mice were randomly(random number) divided into five groups:a sham control group,a sepsis-induced ALI group,and three sepsis groups pre-treated with 20,40,and 80 mg/kg body weight luteolin.Mice in the treatment groups were pre-treated with luteolin at the respective oral dose two days before ALI induction.The lungs were isolated for histopathological examinations,and the bronchoalveolar lavage fluid (BALF) was collected for biochemical analyses.Results Luteolin significantly attenuated sepsis-induced ALI.Additionally,luteolin treatment decreased protein and inflammatory cytokine concentration and the number of infiltrated inflammatory cells in BALF compared with that in the non-treated sepsis mice.Pulmonary myeloperoxidase (MPO) activity was lower in the luteolin-pre-treated sepsis groups than in the sepsis group.The mechanism underlying the protective effect of luteolin on sepsis is related to the up-regulation of certain antioxidation genes,including inducible nitric oxide synthase (iNOS),cyclooxygenase-2 (COX-2),superoxide dismutases (SODs),and heme oxygenase 1 (HO-1),and the reduction of inflammatory responses through blockage of the activation of the nuclear factor (NF)-κB pathway.Conclusions Luteolin pre-treatment inhibits sepsis-induced ALI through its anti-inflammatory and antioxidative activity,suggesting that luteolin may be a potential therapeutic agent for sepsis-induced ALI.
ABSTRACT
Objective To evaluate the reporting item quality of randomized controlled trials of Chinese herbal medicine as an adjunctive therapy for advanced non-small cell lung cancer. Methods The terms including Chinese medicine, Chinese herbal medicine, randomized controlled trials, and non-small cell lung cancer were searched in Chinese and English databases by computer systems to collect relevant literatures. Based on the CONSORT 2010 (consolidated standards of reporting trials 2010), the reporting item quality of the abstracts and main text in eligible papers was evaluated. Results Ninety-five eligible studies were identified from 692 potential eligible articles. None reported all of abstract and main text items in CONSORT 2010. Only 4.12％could be identified as the randomized trial in the title. More than 40％of reports showed the scientific background or rationale in the abstract but not in the main text. Three (3.16％) eligible reports defined the primary or secondary outcome measures. None reported complete information of subjects throughout the clinical trial process. Results A total of 95 eligible papers were collected, of which 0 papers reported complete abstracts and text entries according to the CONSORT. The titles of 4.12％papers were identified as randomized trials. More than 40％of the papers only reported the study purpose or hypothesis in the abstract. 3.16％of the papers reported primary and secondary efficacy index entries, and 0 papers reported complete information of subjects from enrollment to included data analysis sets. Conclusion There is a serious problem of items shortage in the literatures of randomized controlled clinical trials on Chinese herbal medicine as an adjunctive therapy for advanced non-small cell lung cancer. The randomized controlled clinical trials of Chinese herbal medicine as an adjunctive therapy for advanced non-small cell lung cancer should be reported based on the CONSORT to improve the quality of trials.
ABSTRACT
Objective To estimate the diagnostic value of cytology, DNA-ICM(DNA-image cytometry),cytology combined with DNA-ICM for pancreatic malignancy,and to explore the cut-off value for DNA-ICM. Methods Patients with suspicious pancreatic malignancy were retrospectively identified. In total,145 EUS-FNA specimens acquired from 140 separate patients were examined by cytology and DNA-ICM. Diagnostic values among cytology, DNA-ICM and the combination of the techniques in detecting pancreatic malignancy were compared. Results Compared with cytology, DNA-ICM had a lower sensitivity (63.0% VS 82.4%)and accuracy(69.7% VS 85.5%). After combining the techniques, the diagnostic value for pancreatic malignancy significantly improved compared with that by cytology(0.941 VS 0.912, P=0.007 0)or DNA-ICM only(0.941 VS 0.815, P<0.000 1). By using the Youden index, the cut-off value for DNA-ICM to detect pancreatic malignancy was one cell with DI(DNA index)≥2.5. Notably,with this standard, the sensitivity and accuracy of DNA-ICM significantly increased to 72.3% and 77.2%, and those of the combined techniques increased to 91.6% and 93.1%, respectively. Conclusion Automated DNA-ICM is an objective and effective method for pancreatic malignancy. Although DNA-ICM has a lower diagnostic value than that of conventional cytology, an improved value was obtained after combining the techniques.
ABSTRACT
Objective@#To analyze factors influencing antiretroviral therapy (ART) adherence among human immunodeficiency virus (HIV) patients receiving ART at the town level in Ili Kazakh Autonomous Prefecture (Ili) in May 2015 and to document enhanced ART for acquired immunodeficiency syndrome (AIDS) cases.@*Methods@#A cross-sectional survey was conducted using one-on-one interviews and data collection from the system of AIDS follow-up management in three ART services centers at the town level of Ili. The subjects were HIV-infected individuals, aged 18 years or older, who were receiving ART during the survey. The surveys collected demographic characteristics, information related to ART and status of engaging ART, smoking and drinking behavior, depression, and quality of life.@*Results@#A total of 412 participants completed the survey. The age was (41.1±8.0) years (range, 19-67 years). Approximately 60.9% (251) were male and 39.1% (161) were female. The survey showed that 75.0% (309) of participants were in good adherence and the P50 (P25, P75) of quality of life was 56.31 (50.55, 59.42). Females demonstrated better adherence to ART (82.6% (n=133)) than males (70.1% (n=76)) (χ2=8.16, P=0.005). The compliance rate of participants (78.0% (n=54)) with depression was higher than non-depressed participants (63.5% (n=255)) (χ2=7.52, P=0.008). Multivariate logistic regression analyses showed that the probability of good adherence to ART increased with increasing quality of life (OR=1.06, 95%CI:1.02-1.09). Moreover, participants who consumed alcohol or disclosed their HIV infection status to families were less likely to have good adherence to ART (OR=0.26, 95% CI:0.13-0.53 and OR=0.31, 95% CI:0.13-0.72, respectively). Additionally, employed participants were also less likely to have good adherence to ART compared with unemployed participants (OR=0.45, 95% CI:0.21-0.97).@*Conclusion@#HIV/AIDS patients primarily showed good adherence to ART. Factors related to ART adherence included alcohol consumption, informing family of infection, work status, and quality of life.
ABSTRACT
Objective To study the effect of artesunate on inflammatory responses to severe pneumonia by regulating macrophage migration inhibitory factor (MIF) in rats.Methods Total of 100 SD by random (random number) assigned,20 rats were control group,80 SD rats with severe pneumonia were caused by Klebsiella pneumoniae,60 SD rats were treated with different concentrations (20,40,80 mk/kg) of artesunate after modeling.The pathological changes of lung tissue,the level of MIF myeloperoxidase activity and inflammatory cell infiltration in lung tissue of rats were evaluated.Results After treatment with artesunate,the severity of inflammation was significantly alleviated in rats with severe pneumonia evidenced by decrease in myeloperoxidase activity [severe pneumonia:(17.5 ± 1.5) vs.treatment group:(7.5 ±2.0)] and reduction in inflammatory cell infiltration (severe pneumonia:27 × 106 vs.treatment group:12.5 × 106).Similarly,the artesunate also reduced the production of inflammatory cytokines significantly in bronchoalveolar lavage fluid (IL-1 in severe pneumonia group:(1 100 ± 50) pg/ml vs.treatment group:(400 ± 60) pg/ml;IL-6 in severe pneumonia group:(700-± 30) pg/ml vs.treatment group:(200 ±40) pg/ml;IL-10 in severe pneumonia group:(500 ± 70) pg/ml vs.treatment group:(200 ± 40) pg/ml;TNF-αin severe pneumonia group:(500 ± 80) pg/ml vs.treatment group:(150 ± 50) pg/ml.In addition,artesunate inhibited the level and production of MIF,thus inhibiting the inflammatory responses mediated by MIF.Conclusions Artesunate had a protective effect on pneumonia caused by Klebsiella pneumoniae in rats via inhibiting the inflammation responses mediated by MIF.This study provided a molecular basis for newly developed drugs applied to the treatment of pneumonia caused by Klebsiella pneumoniae in rats.

Objective To investigate the drug effect of children with Dent disease who received therapy of po-tassium citrate and thiazide diuretics and angiotensin -converting enzyme inhibitors(ACEI),and to provide the refe-rence for the clinical treatment.Methods Dent disease patient who were followed -up in Bayi Children′s Hospital Af-filiated to Beijing Military Region General Hospital during the period of July 2006 and March 201 4 were selected.The patients were administered a therapy of potassium citrate associated with thiazide diuretics and ACEI according to the level of proteinuria and calciuria and serum potassium.The underlying changes before and after the treatment were com-pared and analyzed.Results In 1 5 children with Dent disease,they were all male cases,onset age ranged from 3 months to 1 1 years old[(2.62 ±3.1 1 )years old],and the disease duration ranged from 0.50 to 9.50 years old [(2.81 ±2.34)years].The patients were followed up for 0.50 to 7.50 years[(3.61 ±2.62)years].There was a sig-nificantly statistical difference in calcium/creatinine and daily Ca -creat ratio in contrast to before treatment[(0.41 ± 0.1 9)mg/mg vs(0.26 ±0.1 2)mg/mg,t =2.603,P =0.021 ;(6.76 ±2.0)mg/kg vs (4.34 ±1 .97)mg/kg,t =5.265,P =0.000],there was no significantly statistical difference in 24 -hour urinary protein quantity in contrast to before treatment[(0.96 ±0.62)g/24 h vs (0.87 ±0.44)g/24 h,t =1 .01 6,P =0.327].One case with kidney stone and 5 cases with nephrocalcinosis had a negative result of renal ultrasound after treatment.Conclusions Treatment of potassium citrate combination with thiazide diuretics and ACEI can significantly decrease urinary calcium excretion, make a disappearance of kidney stone and nephrocalcinosi,and it may have a role in protecting renal function.Treat-ment of benazepril can not significantly decrease the proteinuria and has no substantial improvement in low molecular weight protein urine.
ABSTRACT
Objective To understand the prevalence of HIV infection,syphilis and hepatitis C infection and related risk behaviors among club drug users in Zhejiang province.Methods The drug users were interviewed with questionnaires in 2011 to collect the information about their demographic characteristics,sexual behaviors,drug use behaviors and the utilization of intervention services.Blood samples were collected from them to detect HIV,syphilis and HCV antibodies.Results A total of 3 253 drug users were surveyed,in which 1 298 were club drug users,accounted for 39.9％.The proportion of club drug users was high in northern and central Zhejiang,in females,in age group ≤25 years,in local residents and in those having commercial sexual behaviors during previous 12 months.Of the 1 298 club drug users,91.2％ were methamphetamine users,0.1％ were infected with HIV(95％CI:0.0％-0.2％),8.1％ suffered from syphilis (95％CI:6.6％-9.6％),17.3％ were infected with HCV(95％CI:15.2％-19.4％).Among the interviewed club drug users,12.7％ were aware of AIDS,9.2％ had injecting drug use histories,29.6％ reported having commercial sex during the previous 12 months,only 33.4％ received free condom and counsel,14.0％ received HIV test.Multivariate logistic regression analysis indicated that living in central and southern Zhejiang was associated with syphilis prevalence,HCV infection and injecting drug use behavior,being female was associated with syphilis prevalence.Injecting drug use and commercial sex during the previous 12 months were associated with HCV infection,and injecting drug use and commercial sex during the previous 12 months were associated with each other.Among the 1 285 club drug users,males,local residents in Zhejiang and those who never received free condom or counsel were more likely to have commercial sex.Conclusion The prevalence of syphilis and HCV infection are high and unprotected sexual behaviors are common among the club drug users in Zhejiang,but less intervention services were received by them,suggesting that more attention should be paid to the prevention and control of HIV,HCV infections and syphilis in club drug users by taking effective intervention measures and increasing intervention coverage.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the sexual transmission behaviors among HIV-positive MSM population engaging in unprotected sexual behaviors, as well as the relationship with health conditions and partner notification.</p><p><b>METHODS</b>A total of 308 HIV-positive MSM participants engaged in unprotected sexual behaviors were recruited by "snowballing" sampling in Shanghai and Chengdu. The questionnaire covered such items as the time of HIV infection diagnosis, CD4⁺ T cells count, viral load, antiviral therapy, anxiety and depressive symptoms, sexual partner types and sexual behaviors in the past six months, disclosure to fixed sexual partners and casual sexual partners among others.</p><p><b>RESULTS</b>Of the 308 participants surveyed, the report rate of those having at least one-time sexual transmission behaviors during the past 6 months was 70.1% (216/308). Participants who had primary sexual partners and casual sexual partners following their HIV infection diagnosis accounted for 89.0% (274/308) and 68.2% (210/308) respectively. Of the aforementioned participants, 59.1% (162/274) and 94.3% (198/210) respectively had not disclosed their HIV infection to primary and casual sexual partners. Of thoes who did not disclose their HIV infection to primary sexual partners, 91.9% (147/162) reported sexual transmission behaviors. Of thoes who did not disclose their HIV infection to casual sexual partners, 89.9% (178/198) continue sexual transmission. As found in a multi-factor analysis, the infection risk exposure of those with heterosexual sexual orientation and engagement in sexual transmission behaviors was six times higher than those with homosexual orientation (aOR = 5.896, 95% CI: 1.808-19.232). For those who did not, or partially disclose their HIV infection to male casual sexual partners or commercial sexual partners, the risk exposure of further transmission was 29 times and 19 times higher than those disclose it to their sexual partners (no disclosure: aOR = 28.957, 95% CI: 7.511-65.004; partial disclosure: aOR = 18.956, 95% CI: 6.995-57.417). The highest risk came from those who continue their sexual transmission behavior within six months of their HIV infection diagnosis; the lowest risk came from those continue such behavior more than one year and within two years of their diagnosis (aOR = 0.048, 95% CI: 0.033-0.788); such risk rose to some extent for those continue such behavior over two years of their diagnosis. Compared to those without antiviral therapy, participants with the therapy pose less risk in sexual transmission behaviors.</p><p><b>CONCLUSION</b>More than two-thirds of HIV-positive MSM population who engage in unprotected sexual behaviors reported sexual transmission behaviors. In this regard, increasing antiviral therapy and promoting sexual partner disclosure constituted an effective strategy to minimize further transmission among HIV-positive MSM population. Intervention of sexual transmission behaviors should be addressed to those diagnosed of HIV infection within six months.</p>
