Objective:To explore the application value of renal artery resistance index in the diagnosist of intra-abdominal hypertension (IAH) in critically ill patients.Methods:89 patients with risk factors of IAH in the intensive care unit of Zhangzhou Hospital Affiliated to Fujian Medical University from February 2022 to June 2022 were retrospective analyzed. The intra-abdominal pressure (IAP) were measured by bladder, and patients divided into IAH group (IAP≥12 mmHg) and non-IAH group (IAP <12 mmHg). The resistance index (RI) of the right renal aorta, segment artery and interlobar artery were measured by color Doppler ultrasound. The difference between the measurement indicators of patients in the IAH and non-IAH groups and the correlation with IAP were analyzed. As for different indicators to predict the diagnostic efficacy of IAH, ROC curve analysis was used to evaluate the effect. And further multivariate logistic regression analysis was to find independent risk predictor.Results:A total of 89 patients were included in the study, including 44 patients with normal IAP and 45 patients diagnosed IAH. There were significant differences in the right renal aorta, segmental artery and interlobar artery RI (all P<0.01). The interlobar artery RI≥0.698 was the highest diagnostic cut-off,area under the curve was 0.914, sensitivity was 82.2%, specificity was 97.7%, and Jordon index was 0.799. The Spearman correlation analysis of IAP and the ultrasonographic measurements revealed a strong correlation between right renal interlobar artery RI and IAP ( r=0.741, P<0.01). The multivariate logistic regression analysis showed that the right renal interlobar artery RI ( OR= 24.472, 95% CI:5.122~116.919, P<0.01) was an independent risk predictor of IAH ( P<0.01). Conclusion:Right renal interlobar artery RI had better diagnostic efficacy of IAH,renal ultrasound could be used as an alternative, non-invasive technique for the diagnosis and follow-up of IAH.

A retrospective analysis of the clinical data of seven acute B-lymphoblastic leukemia (B-ALL) patients with TCF3-HLF fusion gene-positive admitted to the First Affiliated Hospital of Soochow University from June 2017 to August 2022 was conducted to summarize their clinical features and prognoses. The seven B-ALL patients comprised four males and three females, with a median age of 18 (11-33) years. Five patients tested positive for CD33 expression, and four patients had a normal karyotype. Two patients had hypercalcemia at the initial diagnosis, and one patient developed hypercalcemia at relapse. Six patients presented with coagulation dysfunction at diagnosis. After induction chemotherapy, five out of seven patients achieved complete remission, of which four subsequently relapsed. Two patients did not achieve remission even after two rounds of induction chemotherapy, with one achieving complete remission after treatment with blinatumomab immunotherapy. Three patients underwent chimeric antigen receptor T cell therapy, whereas three patients subsequently underwent hematopoietic stem cell transplantation. Five patients died, while two patients survived with sustained complete remission. TCF3-HLF-positive B-ALL is rare and has a high relapse rate and poor prognosis.

Objective:To evaluate the outcome of the patients receiving dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) delivered by first-responders who witnessed the out-of-hospital cardiac arrest (OHCA) before the Emergency Medical Service (EMS) arrived.Methods:We performed a search of the relevant literature exploring major scientific databases. We assessed the quality of the included cohort study according to the Cochrane Handbook for Systematic Reviews of Interventions Version 5.1.0. Meta-analysis was performed on three outcome indicators (recovery of spontaneous circulation survival to hospital discharge and survival with favourable neurologic outcome) using the Revman5.3 software.Results:A total of 21 studies with 349 822 patients were selected for the meta-analysis, including 182 125 patients in the DA-CPR group and 167 697 in the CPR-only group. The meta-analysis showed no significant difference between the DA-CPR and CPR-only groups in ROSC [ RR=1.10, 95% confidence interval ( CI): 0.94-1.29, P=0.24], survival to hospital discharge ( RR=1.10, 95% CI: 0.90-1.34, P=0.34) and survival with favourable neurologic outcome ( RR=1.01, 95% CI: 0.79-1.28, P=0.97) of the patients in America, Japan and Korea. However, there was a significant difference between the DA-CPR and the CPR-only groups in ROSC ( RR=2.61, 95% CI:1.53-4.46, P=0.0005), survival to hospital discharge( RR=6.08, 95% CI: 1.84-20.04, P=0.003), and survival with favourable neurologic outcome( RR=9.76, 95% CI: 1.87-51.02, P=0.007) of the patients in China. Conclusions:The overall effect of DA-CPR is significantly different for each country. In detail, DA-CPR offers a survival advantage (Return of spontaneous circulation, survival to hospital discharge and survival with favourable neurologic outcome) over CPR alone in China but no advantage in developed countries.

Chlorfenapyr is a moderately dangerous insecticide widely used in agriculture. The mortality of acute poisoning patients is high, and there is no effective treatment. This paper retrospectively analyzes the clinical data of two cases of compound chlorfenapyr poisoning. The main symptoms of the patients were high fever, sweating, gradual coma, increased creatine kinase and myoglobin, with delayed poisoning symptoms. Despite comprehensive treatment, both patients died eventually. It indicated that chlorfenapyr was highly toxic and had a high mortality. In addition to routine symptomatic treatment for patients with acute poisoning, blood purification treatment should be actively carried out in the early stage.

Objective:To investigate the predictive value of platelet dynamics on the prognosis of 28-day in patients with extracorporeal membrane oxygenation (ECMO).Methods:From January 2017 to December 2020, 60 patients from the Emergency Medicine Center of the First Affiliated Hospital of Nanjing Medical University received ECMO for life support. The baseline data of the patients were collected, the minimum value of platelets on day 1-7 of the machine was calculated, and the platelet change value and change rate were calculated. The patients were divided into the survival group and death group according to the 28-day survival status after ECMO was installed, and the receiver operating curve (ROC) was drawn based on the platelet change value and change rate to evaluate its predictive value for prognosis.Results:Among patients receiving VV-ECMO, the platelet change value and change rate on day 7 had the best prediction effect on the patient's 28-day outcome ( AUCΔPLT7=0.772, P=0.016; AUCΔPLT7%=0.764, P=0.020), when the platelet change value was 4×10 9/L as the critical value, the sensitivity was 0.857, the specificity was 0.615, and when the platelet change rate was -28.99% as the critical value, the sensitivity was 0.857, the specificity was 0.615, and when the platelet change rate was -28.99%. The sensitivity was 0.643 with a specificity of 0.846. In patients receiving VA-ECMO, the platelet change rate on day 6 predicted the best effect on the patient's 28-day outcome ( AUCΔPLT6%= 0.707, P = 0.045). When the platelet change rate was -26.19% as the critical value, the sensitivity was 0.842 and the specificity was 0.643. Conclusions:Platelet dynamic changes of platelets are correlated with the 28-day prognosis of patients receiving ECMO, and the combination of platelet change value and the critical value of change rate can better predict the poor prognosis of patients in both ECMO modes.

Objective:To construct a nomogram model to predict the tolerance of postoperative chemotherapy in endometrial cancer patients by analyzing nutrition-related indexes.Methods:Patients with endometrial cancer who underwent surgery and postoperative chemotherapy in Suzhou Municipal Hospital from July 2013 to July 2019 were included in this study. Some nutrition-related indexes were collected, including age, diabetes, body mass index(BMI), blood albumin, prealbumin, lymphocyte count, hemoglobin, blood platelets, C-reactive protein and blood cholesterol, aspertate aminotransferase, alanine aminotransferase and chemotherapy tolerance. The model for prediction of postoperative chemotherapy tolerance of patients with endometrial cancer were constructed by analyzing these nutrition-related indexes.Results:A total of 83 patients were enrolled, aged from 32 to 81 years, with an average age of (55.15 ± 9.38) years, and BMI were 14.53 - 30.11 kg/m 2, with an average BMI of (22.03 ± 2.93) kg/m 2. All the 83 patients were confirmed as endometrial cancer by postoperative pathology, and received TP or TC chemotherapy after surgery. Before starting chemotherapy, 83 patients were scored on the NRS-2002 scale, 43 were considered to be at risk of malnutrition or nutrition. After receiving chemotherapy, 34 patients developed intolerance to chemotherapy, and the remaining 49 were tolerable. The results of univariate and multivariate regression analysis showed that the presence or absence of diabetes ( HR = 5.634, P = 0.038), lymphocyte count ( HR = 0.146, P = 0.004), and albumin ( HR = 0.857, P = 0.011) were independent influencing factors of chemotherapy tolerance. Conclusions:Diabetes mellitus, lymphocyte count and albumin level can be used to predict the tolerance of chemotherapy in patients with endometrial cancer. The nomogram model of these three nutrition-related indexeshad a good prediction ability to predict the tolerance of chemotherapy in patients with endometrial cancer.

Osteosarcoma is a clinically common primary malignant bone tumor.Its treatment is still not ideal because of the high de-gree of malignancy and early metastasis.Understanding the molecular mechanism and the biological characteristics of malignant os-teosarcoma,and exploring the effective treatment have become the focus of osteosarcoma research at home and abroad.A long non-coding RNA,lncRNA,is involved in the regulation of a variety of cellular functions and plays an important role in the development of osteosarcoma.Recently,lncRNA has been increasingly reported in osteosarcoma research.It has been found to affect the proliferation, invasion,and migration of osteosarcoma cells by interacting with proteins,mRNAs,and miRNAs.This article reviews the research on ln-cRNA based on recent reports regarding its role in the molecular mechanism of osteosarcoma.

Objective To study the levels of interleukin-6 (IL-6) and C-reactive protein(CRP) in umbilical cord serum of the newborns with premature rupture of membrane(PROM)and to explore the value of IL-6 and CRP in the diagnosis of early onset neonatal sepsis (EONS).Method A total of 187 term newborns with PROM ＞ 12 h who were born normal vaginally in our Hospital from April 2015 to December 2015 were enrolled in this study as the PROM group and another 50 term infants without PROM and infection as the control group.The levels of IL-6 and CRP in umbilical cord serum were quantified by ELISA,the results of which were compared between groups.Receiver operating characteristics (ROC) curves were drawn to find out the cut-off value of IL-6 and CRP for the diagnosis of EONS.Result The levels of IL-6 and CRP in umbilical cord serum in the PROM group were significantly higher than those in the control group [IL-6 20.3 (9.5,35.8) pg/ml vs.9.3 (6.9,27.5) pg/ml,CRP 0.42 (0.25,0.78) mg/L vs.0.33 (0.18,0.45) mg/L,P ＜ 0.05].The levels of IL-6 and CRP in the newborns whose mother had chorioamnionitis were significantly higher than those in the newborns whose mother was without chorioamnionitis [IL-6 62.5 (35.2,92.7) pg/ml vs.10.8 (9.3,33.4) pg/ml,CRP 0.86 (0.44,1.95) mg/L vs.0.35 (0.20,0.62) mg/L,P ＜0.05].The levels of IL-6 and CRP in the infants with PROM≥18 h was significantly higher than those in the infants with PROM ＜ 18 h [IL-6 32.1 (9.9,42.2) pg/ml vs.10.7 (9.2,32.6) pg/ml,CRP 0.44(0.29,0.86) mg/L vs.0.35 (0.23,0.61) mg/L,P ＜ 0.05].The levels of IL-6 and CRP in the neonates with EONS was significantly higher than those in the neonates without EONS [IL-6 92.0 (58.3,161.0) pg/ml vs.20.0(9.4,35.2)pg/ml,CRP 1.94(0.47,2.73) mg/L vs.0.38(0.24,0.67) mg/L,P ＜ 0.05].ROC curve analysis showed that the cut-off value of IL-6 and CRP for the diagnosis of EONS were 81.lpg/ml (sensitivity 76.5％,specificity 90.6％) and 1.88mg/L (sensitivity 64.7％,specificity 89.4％).With the combination of IL-6 and CRP levels,the sensitivity was 88.2％ and the specificity was 84.1％ for the diagnosis of EONS.Conclusion To measure the IL-6 and CRP levels in umbilical cord serum is helpful for the early diagnosis of EONS,and the combined detection of the 2 items may improve the sensitivity of diagnosis.

Objective To evaluate the role of ibuprofen and hydrocortisone in early treatment of patent ductus arteriosus ( PDA ) in premature infants with low cortisol level . Method A prospective randomized controlled trial on 144 very low birth weight infants in the Hospital within 24 hours after birth with gestational age of 28~32 weeks and birth weight of 1000~1499 grams,who had asymptomatic PDA diagnosed by echocardiography , introducing early administration of drugs including ibuprofen and /or hydrocortisone within the first 24 ~48 hours after birth.According to the baseline of serum cortisol level measured prior to the administration of drugs , the preterm were assigned into two groups .The low cortisol level group ( the cortisol level <150μg/L) were further subdivided into four groups each being allocated to hydrocortisone or ibuprofen or both of hydrocortisone and ibuprofen combined or placebo treatment .The high cortisol level group ( the cortisol level≥150μg/L) were allocated to either ibuprofen or placebo treatment in randomization.Diameter of ductus arteriosus and cortisol value were measured again after treatment , and the follow-ups were undertaken till discharge .All data was collected and analyzed by statistical software .Result A total of 91 cases were in low cortisol level group ( 22 cases of hydrocortisone , 23 cases of ibuprofen , 21 cases of both hydrocortisone and ibuprofen , and 25 cases of placebo ) and 53 cases in high cortisol level group (26 cases of placebo and 27 cases of Ibuprofen ).Low cortisol level group , combined therapy , closure of the ductus at a rate of 81.0%, was higher than other methods of therapy ( P<0.05);high cortisol level group, the ductus arteriosus closed in 20 patients of ibuprofen therapy ( 74.1%) and in 13 patients of placebo treatment (50.0%) (P<0.05).Early treatment did not significantly increase the drug adverse effects, including impaired renal function , gastrointestinal bleeding , hyperglycemia and others. After comparisons between laboratory changes in early targeted groups and non-early targeted groups after treatment, findings were as follows: decrease in the incidence of apnea , myocardial damage , feeding intolerance , intraventricular hemorrhage and reduce the duration of phototherapy .Conclusion This trial proved the efficacy and safety of early therapy with ibuprofen and hydrocortisone for closure of ductus arteriosus in premature infants with low cortisol level and the decreasing incidence of complications due to PDA without increasing the risk of adverse effects .
