Expression and clinical significance of serum lncRNA SNHG16 and SMAD4 in elderly COPD patients with PI / 国际检验医学杂志

Objective To investigate the expression and clinical significance of serum long non-coding RNA small nucleolar RNA host gene 16(lncRNA SNHG16)and mothers against decapentaplegic homolog 4(SMAD4)in elderly patients with chronic obstructive pulmonary disease(COPD)and pulmonary infection(PI).Methods A total of 237 elderly COPD patients admitted to the hospital from January 2021 to January 2023 were enrolled in the study.Among them,117 patients with concomitant PI were classified as the concur-rent group,and 120 patients without concomitant PI were classified as the COPD group.Real-time fluores-cence quantitative polymerase chain reaction(qRT-PCR)was applied to detect the expression level of serum lncRNA SNHG16 in two groups.Enzyme linked immunosorbent assay(ELISA)was applied to detect the lev-el of SMAD4 in patients'serum.Simplified clinical pulmonary infection scale(sCPIS)was used to evaluate the degree of PI of patients in the concurrent group.Multivariate Logistic regression was applied to analyze the in-fluencing factors of PI in elderly COPD patients.Correlation between serum lncRNA SNHG16,SMAD4 levels and sCPIS in elderly COPD patients with PI was analyzed by using Spearman correlation analysis.Receiver op-erating characteristic(ROC)curve was applied to analyze the diagnostic value of serum lncRNA SNHG16 and SMAD4 levels in elderly COPD patients with PI.Results The serum relative expression level of lncRNA SNHG16 in the concurrent group was higher than that in the COPD group,but the serum SMAD4 level was lower than that in the COPD group(P<0.05).In addition,the proportions of patients with age≥70 years,smoking history,complicated with diabetes and COPD course≥5 years and the levels of tumor necrosis fac-tor-α(TNF-α),interferon-γ(INF-γ)in the concurrent group were higher than those in the COPD group,and FEV1/FVC and the level of interleukin-10(IL-10)in concurrent group were lower than those in COPD group(P<0.05).Multivariate Logistic analysis showed that age≥70 years old,complicated with diabetes,COPD course≥5 years,high levels of TNF-α,INF-γ and lncRNA SNHG16 were risk factors for elderly patients with COPD complicated with PI(P<0.05),but high FEV1/FVC and high levels of SMAD4 and IL-10 were protective factors(P<0.05).Spearman correlation analysis showed that serum relative expression level of ln-cRNA SNHG16 was positively correlated with sCPIS in COPD patients with PI(r=0.505,P<0.001),while SMAD4 level was negatively correlated with sCPIS(r=-0.550,P<0.001).The area under the curve(AUC)of the combined diagnosis of serum lncRNA SNHG16 and SMAD4 for PI in elderly COPD patients was higher than those of individual diagnosis(Z=2.416,P=0.016;Z=2.375,P=0.018).Conclusion The serum relative expression level of lncRNA SNHG16 increases and SMAD4 level decreases in elderly COPD pa-tients with PI,both are influencing factors for elderly COPD patients complicated with PI,and both are related to the degree of PI in patients,and both have diagnostic value for elderly COPD patients complicated with PI,and the diagnostic efficacy of combined detection is better.

Association between serum 25-hydroxyvitamin D and high-sensitivity C reactive protein levels in health check-ups population / 中华健康管理学杂志

Objective:To explore the association between serum 25-hydroxyvitamin D [25-(OH)D] and high-sensitivity C reactive protein (hs-CRP) levels in health check-ups population.Methods:A total of 746 patients who underwent health check-ups at an enterprise unit in Hefei city were selected as the study subjects with an average age of (47.2±15.6) years and 489 males, accounting for 65.5%. Demographical and disease information was collected through questionnaires. Serum 25-(OH)D and hs-CRP levels were measured. The subjects were divided into three groups according to the 25-(OH)D level: non-deficient group (≥50 nmol/L), deficient group (25 nmol/L to 49.9 nmol/L), severely deficient group (<25 nmol/L). C-reactive protein was divided into normal group and high value group by 75% percentile. Multivariate logistic regression was used to analyze the relationship between 25-(OH)D and hs-CRP levels.Results:The proportions of high CRP levels in the severely deficient, deficient, and non-deficient groups were 29.8%, 26.4%, and 17.0%, respectively, and the difference was statistically significant (χ2=6.471， P<0.05). Logistic regression analysis showed that, compared with the non-deficient group of 25-(OH)D, the odds ratios values (95% CI) of the high values of hs-CRP in the deficient group and the severely deficient group of 25-(OH)D were 1.851(1.122 to 3.053) and 2.369(1.227 to 4.573), respectively. Conclusions:Serum 25-(OH)D level is a risk factor for hs-CRP in adults. Nutritional intervention in vitamin D deficient population may be beneficial to reduce the level of inflammation.

Prognostic value of differences between peripheral arterial and venous blood gas analysis in patients with septic shock / 中华危重病急救医学

Objective To investigate the value of the difference between peripheral arterial and venous blood gas analysis for the prognosis of patients with septic shock after resuscitation.Methods Patients with septic shock aged 18 to 80 years admitted to intensive care unit (ICU) of Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine from May 2016 to December 2017 were enrolled. The peripheral arterial blood and peripheral venous blood gas analysis were measured simultaneously after the early 6 hours resuscitation, including pH, partial pressure of oxygen (PO2), partial pressure of carbon dioxide (PCO2), base excess (BE), bicarbonate (HCO3-) and lactate (Lac) level, and the difference values between peripheral arterial and venous blood were calculated. According to the 28-day survival, the patients were divided into survival group and death group. Multiple Logistic regression analysis was used to analyze the risk factors of death, and the receiver operating characteristic curve (ROC) was used to analyze the prognostic value of blood gas analysis parameters for prognosis.Results A total of 65 patients with septic shock resuscitation were enrolled in the study, 35 survived while 30 died during the 28-day period. ① There was no significant difference in gender, age, and mean arterial pressure (MAP), central venous pressure (CVP), central venous oxygen saturation (ScvO2) and norepinephrine (NE) dose between the two groups.② The arterial and venous Lac, the difference of Lac (ΔLac) and PCO2 (ΔPCO2) between arterial and venous blood in death group were significantly higher than those in survival group [arterial Lac (mmol/L): 7.40±3.10 vs. 4.82±2.91, venous Lac (mmol/L): 9.17±3.27 vs. 5.81±3.29, ΔLac (mmol/L): 1.77±0.54 vs. 0.99±0.60, ΔPCO2 (mmHg, 1 mmHg =0.133 kPa): 9.64±5.08 vs. 6.70±3.71, allP < 0.01], and there was no significant difference in the other arterial and venous blood gas analysis index and its corresponding differential difference between two groups. ③ Multiple Logistic regression analysis showed that ΔPCO2 [β = 0.247, odd ratio (OR) = 1.280, 95％ confidential interval (95％CI) = 1.057-1.550,P = 0.011], and ΔLac (β = 2.696,OR = 14.820, 95％CI = 2.916-75.324,P = 0.001) were the independent risk factors for the prognosis of septic shock. ④ It was shown by ROC curve analysis that arterial blood Lac, ΔLac andΔPCO2 had predictive value on prognosis of septic shock, the area under ROC curve (AUC) was 0.792, 0.857, 0.680, respectively (allP < 0.05). When the best cut-off value of arterial Lac was 4.00 mmol/L, the sensitivity was 100％, and the specificity was 62.86％ for predictor of death in 28-day; when the best cut-off value of ΔLac was 1.25 mmol/L, the sensitivity was 93.33％, and the specificity was 68.57％ for predictor of death in 28-day; when the best cut-off value of ΔPCO2 was 4.35 mmHg, the sensitivity was 83.33％, and the specificity was 37.14％ for predictor of death in 28-day.Conclusions Compared to other parameters, the difference between peripheral arterial and venous blood gas analysis, ΔPCO2 and ΔLac had the best correlation with the prognosis of septic shock. The ΔPCO2 and ΔLac are the independent prognostic predictors for 28-day survival.

Prognostic value of difference between peripheral venous and arterial partial pressure of carbon dioxide in patients with septic shock: a pilot study / 南方医科大学学报

OBJECTIVE@#To evaluate the prognostic value of the difference between peripheral venous and arterial partial pressure of carbon dioxide in patients with septic shock following early resuscitation.@*METHODS@#This prospective study was conducted among the patients with septic shock treated in our department during the period from May, 2017 to May, 2018. Peripheral venous, peripheral arterial and central venous blood samples were collected simultaneously and analyzed immediately at bedside after 6-h bundle treatment. Arterial blood lactate concentration (Lac) and the arterial (PaCO), peripheral venous (PpvCO) and central venous partial pressure of carbon dioxide (PcvCO) were recorded. The differences between PpvCO and PaCO (Ppv-aCO) and between PcvCO and PaCO (Pcv-aCO) were calculated. Pearson correlation analysis was used to test the agreement between Pcv-aCO and Ppv-aCO. Multivariable logistic regression analysis was performed to analyze the possible risk factors for 28-day mortality, and the receiver-operating characteristic curve (ROC) was plotted to assess the prognostic values of these factors for 28-day mortality.@*RESULTS@#A total of 62 patients were enrolled in this study, among who 35 survived and 27 died during the 28-day period. Compared with the survivor group, the patients died within 28 days showed significantly higher Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score (24.2±6.0 20.5±4.9, =0.011), sequential organ failure assessment (SOFA) score (14.9±4.7 12.2±4.5, =0.027), PcvaCO (5.5±1.6 7.1±1.7, < 0.001), PpvaCO (7.1±1.8 10.0±2.7, < 0.001), and arterial lactate level (3.3±1.2 4.2±1.3, =0.003) after 6-h bundle treatment. Pearson correlation analysis showed that Ppv-aCO was significantly correlated with Pcv-aCO (=0.897, R= 0.805, < 0.001). Multiple logistic regression analysis identified Ppv-aCO (β=0.625, =0.001, OR=1.869, 95% CI: 1.311-2.664) and lactate level (β=0.584, =0.041, OR=1.794, 95%CI: 1.024-3.415) as the independent risk factors for 28-day mortality. The maximum area under the ROC (AUC) of Ppv-aCO was 0.814 (95%CI: 0.696- 0.931, < 0.001), and at the best cut- off value of 9.05 mmHg, Ppv-aCO had a sensitivity of 70.4% and a specificity of 88.6% for predicting 28-day mortality. The AUC of lactate level was 0.732 (95%CI: 0.607-0.858, =0.002), and its sensitivity for predicting 28-day mortality was 70.4% and the specificity was 74.3% at the best cut-off value of 3.45 mmol/L; The AUC of Pcv-aCO was 0.766 (95%CI: 0.642-0.891, < 0.001), and its sensitivity was 66.7% and the specificity was 80.0% at the best cut-off value of 7.05 mmHg.@*CONCLUSIONS@#A high Ppv-aCO after early resuscitation of septic shock is associated with poor outcomes. Ppv-aCO is well correlated with Pcv-aCO and can be used as an independent indicator for predicting 28-day mortality in patients with septic shock.

One case report of neonatalCandida arthritis / 临床儿科杂志

ObjectiveTo explore the clinical characteristics, diagnosis and treatment of neonatalCandida arthritis. Methods The clinical data from one case of neonatalCandida arthritis with swelling and pain in multiple joints as the ifrst symp-toms were reviewed.Results Boy born at 31 weeks' gestational age had the birth weight of 2100 g. The patients was admitted to neonatal intensive care unit after birth and treated with antibiotics for a long time due to infection. At 24 days after birth, blood culture showed the growth ofCandida albicans. At 29 days after birth, the bilateral knee joints showed swelling. TheCandida arthritis was diagnosed through X ray and joint-cavity lfuid culture. The patient was treated with Fluconazole for 13 weeks. When discharged, the joints swelling had been disappeared, while the muscle tension of the double upper limbs was signiifcantly weak. The shoulders had visible slight activities independently. The ifngers, wrists and elbows had less independent activities. The muscle tension of the double lower limbs was slight and the independent activity was more than upper limbs, but the extend was smaller than normal. The palmar grasp relfex was weak. The 30 months follow-up showed that each joint had even length, no abnormality and normal activities. The language and intelligence were normal.Conclusions NeonatalCandida arthritis is mostly combined with or secondary to systemic disseminated candidiasis, and the priority therapy is antifungal drugs. Surgical operation can be considered if necessary, which can improve the prognosis.

Establishment of rat experiment model of chronic allograft nephropathy / 中华器官移植杂志

Objective To summarize the experience of establishing the stable rat model of chronic allograft nephropathy. Methods We used Fisher rats as donors and Lewis rats as recipients.After the left kidney of the donor perfused in situ under hypothermic condition, the left renal vein,abdominal aorta and bladder flap of the donor was anastomosed with the left renal vein, renal artery and bladder of the recipient, respectively. The recipients were given cyclosporin oral solution 10 mg/kg every day by gavage for 10 days after transplantation. The blood and urine samples were collected 1 month, 2 months and 4 months after transplantation and renal function and total urine protein were examined. The pathological changes of the renal allograft were observed 2 and 4 months after transplantation. Results Forty-five rats received operation and achievement ratio was 85%. The renal transplantations were finished in 120 ± 20 min. The Scr, BUN, Cycs and total urine protein demonstrated a significant increase one month after transplantation. On the second and fourth month,with the exception of urine protein continued to increase, the other indicators did not change significantly. Two months after transplantation renal pathology demonstrated light to moderate interstitial fibrosis, infiltration of lymphocytes and plasma cells. At 4th month the renal allografts showed extensive interstitial fibrosis, a large number of infiltrating interstitial cells, thickening,hardening, occlusion of glomerular basement membrane, and renal tubular atrophy that were consistent with pathological changes of chronic allograft nephropathy. Conclusion Through adequate surgical training and improvement, and specification for rat nephrectomy, transplantation surgery,and postoperative management in every detail, the model with high success rate and stability can be achieved.

CLINICAL SIGNIFICANCE OF EARLY ROUTINE ALLOGRAFT BIOPSY IN KIDNEY TRANSPLANTATION / 解放军医学杂志

Six five renal graft biopsies were performed routinely in 36 renal transplantation patients with normal renal function 1 and 3 months after transplantation. All the patients were given the immunosuppressive regimen of cyclosporine A (CsA), prednisone (Pred), azathioprine (Aza) and Tripterygium Wilfordii Hook (TW). The histological diagnosis of allograft biopsy was made according to the Banff schema. In 18 45% of the biopsies (12/65), early subclinical rejection or borderline changes were found. There was a significant difference for different dosages of TW, but no difference for the dosages of CsA, Pred and Aza intravenous between patients with pathological changes and those without. The patients with early subclinical rejection or borderline changes, methylpredisolone was given in bolus, followed by the adjustment of immunosuppressive regimens. With this treatment, there was no difference in 5 year survival rate between them and those with normal renal allograft biopsy findings. The routine allograft biopsy helps discover early subclinical rejection and borderline changes in patients with renal transplantation, and beneficial for adjustment of immunosuppressive therapy.
