Analysis of lymphocyte subsets in patients with sepsis and its impact on prognosis / 中华危重病急救医学

OBJECTIVE@#To explore the characteristics of changes in peripheral blood lymphocyte subsets in patients with sepsis in intensive care unit (ICU) and analyze their predictive value for prognosis.@*METHODS@#The clinical data of sepsis patients admitted to the surgical intensive care unit (SICU) of the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2021 were analyzed retrospectively. The patients met the diagnostic criteria of Sepsis-3 and were ≥ 18 years old. Peripheral venous blood samples were collected from all patients on the next morning after admission to SICU for routine blood test and peripheral blood lymphocyte subsets. According to the 28-day survival, the patients were divided into two groups, and the differences in immune indexes between the two groups were compared. Logistic regression analysis was used to analyze the risk factors of immune indexes that affect prognosis.@*RESULTS@#(1) A total of 279 patients with sepsis were enrolled in the experiment, of which 198 patients survived at 28 days (28-day survival rate 71.0%), and 81 patients died (28-day mortality 29.0%). There were no significant differences in age (years old: 57.81±1.71 vs. 54.99±1.05) and gender (male: 60.5% vs. 63.6%) between the death group and the survival group (both P > 0.05), and the baseline data was comparable.(2) Acute physiology and chronic health evalution II (APACHE II: 22.06±0.08 vs. 14.08±0.52, P < 0.001), neutrophil percentage [NEU%: (88.90±1.09)% vs. (84.12±0.77)%, P = 0.001], procalcitonin [PCT (μg/L): 11.97±2.73 vs. 5.76±1.08, P = 0.011], platelet distribution width (fL: 16.81±0.10 vs. 16.57±0.06, P = 0.029) were higher than those in the survival group, while lymphocyte percentage [LYM%: (6.98±0.78)% vs. (10.59±0.86)%, P = 0.012], lymphocyte count [LYM (×109/L): 0.70±0.06 vs. 0.98±0.49, P = 0.002], and platelet count [PLT (×109/L): 151.38±13.96 vs. 205.80±9.38, P = 0.002], and thrombocytocrit [(0.15±0.01)% vs. (0.19±0.07)%, P = 0.012] were lower than those in the survival group. (3) There was no statistically significant difference in the percentage of lymphocyte subsets between the death group and the survival group, but the absolute value of LYM (pieces/μL: 650.24±84.67 vs. 876.64±38.02, P = 0.005), CD3+ absolute value (pieces/μL: 445.30±57.33 vs. 606.84±29.25, P = 0.006), CD3+CD4+ absolute value (pieces/μL: 239.97±26.96 vs. 353.49±18.59, P = 0.001), CD19+ absolute value (pieces/μL: 111.10±18.66 vs. 150.30±10.15, P = 0.049) in the death group was lower than those in the survival group. Other lymphocyte subsets in the death group, such as CD3+CD8+ absolute value (pieces/μL: 172.40±24.34 vs. 211.22±11.95, P = 0.112), absolute value of natural killer cell [NK (pieces/μL): 101.26±18.15 vs. 114.72±7.64, P = 0.420], absolute value of natural killer T cell [NKT (pieces/μL): 33.22±5.13 vs. 39.43±2.85, P = 0.262], CD4-CD8- absolute value (pieces/μL: 41.07±11.07 vs. 48.84±3.31, P = 0.510), CD4+CD8+ absolute value (pieces/μL: 3.39±1.45 vs. 3.47±0.36, P = 0.943) were not significantly different from those in the survival group. (4)Logistic regression analysis showed that lymphocyte subsets were not selected as immune markers with statistical significance for the prognosis of sepsis.@*CONCLUSIONS@#The changes of immune indexes in sepsis patients are closely related to their prognosis. Early monitoring of the above indexes can accurately evaluate the condition and prognosis of sepsis patients.

Prognostic evaluation of coagulation indicators for patients with acute fatty liver of pregnancy / 中华危重病急救医学

OBJECTIVE@#To explore the relevant clinical test indicators that affect the prognosis of patients with acute fatty liver of pregnancy (AFLP), and to provide a basis for early diagnosis and correct selection of treatment methods.@*METHODS@#A retrospective analysis was conducted. Clinical data of AFLP patients in the intensive care unit (ICU) of the First Affiliated Hospital of Zhengzhou University from January 2010 to May 2021 were collected. According to the 28-day prognosis, the patients were divided into death group and survival group. The clinical data, laboratory examination indicators, and prognosis of the two groups were compared, and further binary Logistic regression analysis was used to analyze the risk factors affecting the prognosis of patients. At the same time, the values of related indicators at each time point (24, 48, 72 hours) after the start of treatment were recorded. The receiver operator characteristic curve (ROC curve) of prothrombin time (PT) and international normalized ratio (INR) for evaluating the prognosis of patients at each time point was drawn, and the area under the ROC curve (AUC) was calculated to evaluate the predictive value of relevant indicators at each time point for the prognosis of AFLP patients.@*RESULTS@#A total of 64 AFLP patients were selected. The patients developed the AFLP during pregnancy (34.5±6.8) weeks, with 14 deaths (mortality of 21.9%) and 50 survivors (survival rate of 78.1%). There was no statistically significant difference in general clinical data between the two groups of patients, including age, time from onset to visit, time from visit to cessation of pregnancy, acute physiology and chronic health evaluations II (APACHE II), hospitalization time in ICU, and total hospitalization cost. However, the proportion of male fetuses and stillbirths in the death group was higher than that in the survival group. The laboratory examination indicators including the white blood cell count (WBC), alanine transaminase (ALT), serum creatinine (SCr), PT extension, INR elevation, and hyperammonia in the death group were significantly higher than those in the survival group (all P < 0.05). Through Logistic regression analysis of the above indicators showed that PT > 14 s and INR > 1.5 were risk factors affecting the prognosis of AFLP patients [PT > 14 s: odds ratio (OR) = 1.215, 95% confidence interval (95%CI) was 1.076-1.371, INR > 1.5: OR = 0.719, 95%CI was 0.624-0.829, both P < 0.01]. ROC curve analysis showed that both PT and INR at ICU admission and 24, 48, and 72 hours of treatment can evaluate the prognosis of AFLP patients [AUC and 95%CI of PT were 0.772 (0.599-0.945), 0.763 (0.608-0.918), 0.879 (0.795-0.963), and 0.957 (0.904-1.000), respectively; AUC and 95%CI of INR were 0.808 (0.650-0.966), 0.730 (0.564-0.896), 0.854 (0.761-0.947), and 0.952 (0.896-1.000), respectively; all P < 0.05], the AUC of PT and INR after 72 hours of treatment was the highest, with higher sensitivity (93.5%, 91.8%) and specificity (90.9%, 90.9%).@*CONCLUSIONS@#AFLP often occurs in the middle and late stages of pregnancy, and the initial symptoms are mainly gastrointestinal symptoms. Once discovered, pregnancy should be terminated immediately. PT and INR are good indicators for evaluating AFLP patient efficacy and prognosis, and PT and INR are the best prognostic indicators after 72 hours of treatment.

Objective:To investigate the predictive value of the maximum aggregation rate (MAR) of platelet for septic shock and septic shock with disseminated intravascular coagulation (DIC).Methods:A retrospective case-control study enrolled patients with sepsis admitted to department of critical care medicine of the First Affiliated Hospital of Zhengzhou University from January 2021 to November 2022. The basic data, dynamic platelet aggregation rate, blood routine, inflammation indicators, sequential organ failure assessment (SOFA) and other clinical indicators within 24 hours after admission were collected. Septic patients were divided into the shock group and the non-shock group according to the presence of septic shock; then refer to the International Society on Thrombosis and Hemostasis (ISTH) standard, patients with septic shock were divided into the shock DIC group and the shock non-DIC group according to the presence of dominant DIC. Compared the differences in platelet aggregation function between these groups, and the receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of the MAR for septic shock and septic shock with DIC. Spearman correlation analysis was used to analyze the correlation of MAR with inflammation indicators and the severity of illness in patients with sepsis.Results:A total of 153 sepsis patients were included and 61 with septic shock (including 17 with dominant DIC and 44 without dominant DIC). Compared with the non-shock group, the level of procalcitonin (PCT), C-reactive protein (CRP), and SOFA score were significantly higher in the shock group [PCT (mg/L): 6.90 (2.50, 23.50) vs. 0.87 (0.26, 5.75), CRP (mg/L): 156.48 (67.11, 230.84) vs. 90.39 (46.43, 182.76), SOFA score: 11.00 (8.00, 14.00) vs. 5.00 (3.00, 8.00), all P < 0.05]. The platelet count (PLT) and the MAR induced by adenosine diphosphate (ADP), adrenaline (A), collagen (COL), and arachidonic acid (AA; ADP-MAR, A-MAR, COL-MAR, AA-MAR) in the shock group were significantly decreased [PLT (×10 9/L): 101.00 (49.00, 163.50) vs. 175.50 (108.25, 254.50), ADP-MAR: 28.50% (22.00%, 38.05%) vs. 45.90% (33.98%, 60.28%), A-MAR: 38.90% (30.00%, 55.40%) vs. 65.15% (54.38%, 72.53%), COL-MAR: 27.90% (20.85%, 36.55%) vs. 42.95% (33.73%, 54.08%), AA-MAR: 24.70% (16.40%, 34.20%) vs. 46.55% (28.33%, 59.20%), all P < 0.05]. Subgroup analysis revealed that, compared with the shock non-DIC group, the SOFA scores were significantly higher in patients in the shock DIC group (13.29±5.23 vs. 10.39±3.58, P < 0.05), the PLT and COL-MAR in the shock DIC group were significantly reduced [PLT (×10 9/L): 36.00 (22.00, 67.50) vs. 115.50 (84.25, 203.75), COL-MAR: 21.50% (17.85%, 32.60%) vs. 30.95% (22.98%, 38.53%), all P < 0.05]. ROC curve analysis showed that A-MAR had a higher predictive value for septic shock, and the area under the ROC curve (AUC) was 0.814 [95% confidence interval (95% CI) was 0.742-0.886, P = 0.000]. When the optimal cut-off value was 51.35%, the sensitivity was 68.9%, the specificity was 82.6%, the positive predictive value was 0.724 and the negative predictive value was 0.800. COL-MAR had some predictive value for septic shock with DIC, and the AUC was 0.668 (95% CI was 0.513-0.823, P = 0.044). When the optimal cut-off value was 21.90%, the sensitivity was 52.9%, the specificity was 79.5%, the positive predictive value was 0.500, and the negative predictive value was 0.813. Spearman correlation analysis showed that the MAR induced by each inducer was negatively correlated with inflammatory indicators and SOFA scores in sepsis patients, with A-MAR showing the strongest correlation with SOFA score ( r = -0.327, P = 0.000). Conclusions:MAR, an indicator of platelet aggregation function, shows predictive value for septic shock and septic shock with DIC, and it could be used to for evaluating the severity of patients with sepsis. In addition, tt alsocan be used as a monitoring index to predict the changes of sepsis patients and to guide the treatment.

OBJECTIVE@#To observe the expression level of cytokines in patients with sepsis and its effect on prognosis.@*METHODS@#The clinical data of sepsis patients admitted to the intensive care unit (ICU) of the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2022 were analyzed retrospectively, including gender, age, and acute physiology and chronic health evaluation II (APACHE II), blood routine, procalcitonin (PCT), C-reactive protein (CRP), and cytokines levels [interleukins (IL-2, IL-4, IL-6, IL-10, IL-17), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ)] within 24 hours of admission to ICU. The 28-day prognosis of the patients was followed up. The patients were divided into survival group and death group according to the prognosis. The clinical data between the two groups of sepsis patients with different prognosis were compared. Binary Logistic regression analysis was used to analyze the independent risk factors affecting the prognosis of patients with sepsis, and the receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of each risk factor for the prognosis of patients with sepsis.@*RESULTS@#(1) A total of 227 patients with sepsis were enrolled, including 168 patients in the survival group (survival rate 74.0%) and 59 patients in the death group (mortality 26.0%). There were no significant differences in age (years old: 55.97±2.13 vs. 54.67±1.11) and gender (male: 71.2% vs. 57.1%) between the death group and the survival group (both P > 0.05), indicating that the baseline data of the two groups were comparable. (2) The APACHE II (19.37±0.99 vs. 14.88±0.61, P < 0.001) and PCT (μg/L: 12.39±2.94 vs. 4.14±0.90, P < 0.001) in the death group were significantly higher than those in the survival group, while the platelet count [PLT (×109/L): 144.75±12.50 vs. 215.99±11.26, P = 0.001] and thrombocytocrit [(0.14±0.01)% vs. (0.19±0.01)%, P = 0.001] were significantly lower than those in the survival group. (3) The level of IL-6 in the death group was significantly higher than that in the survival group (ng/L: 577.66±143.16 vs. 99.74±33.84, P < 0.001). There were no statistically significant differences in other cytokines, IL-2, IL-4, IL-10, TNF-α, IFN-γ and IL-17 between the death group and the survival group [IL-2 (ng/L): 2.44±0.38 vs. 2.63±0.27, P = 0.708; IL-4 (ng/L): 3.26±0.67 vs. 3.18±0.34, P = 0.913; IL-10 (ng/L): 33.22±5.13 vs. 39.43±2.85, P = 0.262; TNF-α (ng/L): 59.33±19.21 vs. 48.79±29.87, P = 0.839; IFN-γ (ng/L): 6.69±5.18 vs. 1.81±0.16, P = 0.100; IL-17 (ng/L): 2.05±0.29 vs. 2.58±0.33, P = 0.369].

Minimally invasive techniques for treatment of special cardiac malformations / 中国胸心血管外科临床杂志

@#Objective    To share the experience of treating special cardiac malformations by applying minimally invasive techniques. Methods    Eight children with special cardiac malformations admitted to our hospital from July 2014 to September 2020 were recruited, including 3 males and 5 females, aged 0.8-1.2 (1.1±0.4) years, and weighted 7.8-11.5 (9.6±2.9) kg. There were 2 patients of huge muscular ventricular septal defect (VSD), 3 perimembranous cribriform VSD, 1 right coronary-right atrial fistula, 1 right coronary-right ventricular fistula, and 1 young, low-weight child with large aortopulmonary. All were treated with minimally invasive techniques using transesophageal echocardiography (TEE) as a guiding tool. All children received intraoperative TEE immediately to evaluate the curative effect of the surgery, and all went to outpatient clinic for reexamination of echocardiography, electrocardiogram and chest X-ray after discharge. Results    Eight children underwent minimally invasive surgery successfully without any incision infection, intracardiac infection, arrhythmia or pericardial effusion. None of the 8 children were lost to follow-up, and the results of all reexaminations were satisfactory. Conclusion    The application of minimally invasive techniques is a bold and innovative attempt for the treatment of a few special types of cardiac malformations. It has significant advantages in reducing trauma and medical costs in some suitable patients, and has certain clinical reference values.

Diagnosis and treatment of primary cardiac tumors in pediatric patients / 中华实用儿科临床杂志

Objective:To summarize the experience in diagnosis and treatment of primary cardiac tumors in pediatric patients.Methods:Retrospectively analyzing 7 pediatric patients who were suspected as primary cardiac tumors and diagnosed and treated in Department of Heart Center, Children′s Hospital of Dalian Medical University from August 2013 to February 2019.All patients underwent echocardiography and other examinations, so as to confirm the diagnosis and the treatment plan was chosen based on the size and location of the tumor.All patients were followed up after discharge.Results:A total of 7 patients were diagnosed as primary cardiac tumors by echocardiography, among which 5 cases underwent surgical treatment, and 2 cases were diagnosed with tuberous sclerosis without surgery.In children undergoing surgery, 1 patient underwent autologous heart transplantation to remove the tumor, 1 patient had arrhythmia, 1 patient had mitral regurgitation after surgery, and the mitral regurgitation was corrected again.The remaining children had no adverse complications and were discharged successfully.Histologic examination revealed rhabdomyoma in 4 patients, and fibroma in 1 patient.The patients were followed up for 2-66 months after discharge, and no tumor recurrence was observed in the children who performed surgery.There was a trend of spontaneously regress of cardiac tumor in 2 patients without surgery.Conclusions:Echocardiography is the first choice for the diagnosis of primary cardiac tumors in Pediatric patients.Rhabdomyoma is the most prevalent histologic type of primary cardiac tumors, and tuberous sclerosis should be excluded during the diagnosis process.Patients with tuberous sclerosis selected conservative treatment, and surgical treatment was selected for children with obvious symptoms.According to the location and size of lesion, therapy strategies should be chosen and autologous heart transplantation can be adopted to remove the tumor for children with large tumors.Autologous heart transplantation to remove the tumor is a good surgical treatment.

Transthoracic echocardiography-guided percutaneous intervention for treatment of atrial septal defect complicated with pulmonary valvular stenosis in children / 中华全科医师杂志

Clinical data of 23 children with atrial septal defect and pulmonary valvular stenosis admitted in Dalian Children′s Hospital during March 2015 to March 2018 were retrospectively analyzed. Twenty patients were treated with percutaneous closure of atrial septal defect through femoral vein first, then transthoracic echocardiography-guided balloon pulmonary valvuloplasty was performed; while 3 patients had no balloon pulmonary valvuloplasty after percutaneous closure of atrial septal defect. Patients were followed up by transthoracic echocardiography and all were doing well. The transvalvular pressure fell under 35 mmHg (1 mmHg=0.133 kPa) [(19.5±1.9)mmHg] in all patients, which was significantly lower than that before treatment [(62.0±7.8 mmHg)] (t=28.92, P<0.01). During follow-up, no residual shunt of atrial septal defect was found; and mild pulmonary regurgitation occurred in 3 cases. The study indicates that combined percutaneous treatment with transthoracic echocardiography guidance is effective and safe for children with atrial septal defect and pulmonary valvular stenosis. The pulmonary artery stenosis of some patients can be alleviated, after closuring of the atrial septal defect.

Effect of Xuebijing on inflammatory response and prognosis in patients with septic shock / 中华危重病急救医学

Objective:To study the effect of Xuebijing on inflammatory response and prognosis in patients with septic shock.Methods:A prospective randomized controlled study was conducted. Eighty septic shock patients admitted to department of critical care medicine of the First Affiliated Hospital of Zhengzhou University from January to December in 2019 were enrolled. The enrolled patients were divided into Xuebijing group and control group by randomized number table method, with 40 cases in each group. Both groups were strictly followed the guidelines for the diagnosis and treatment of septic shock to take comprehensive treatment measures against sepsis. On this basis, Xuebijing group received intravenous 100 mL Xuebijing injection twice a day for 7 days. Baseline data of enrolled patients were recorded. The levels of interleukin-6 (IL-6), procalcitonin (PCT), C-reactive protein (CRP) and heparin binding protein (HBP) were measured before treatment and 3, 7 and 10 days after treatment. Mechanical ventilation time, the length of intensive care unit (ICU) stay, total hospitalization time and 28-day mortality were recorded. The differences of every indicator between the two groups were compared. Independent risk factors affecting patient prognosis were analyzed by binary Logistic regression.Results:① There was no significant difference in baseline data such as gender, age, infection site, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure score (SOFA) between the two groups. ② The levels of serum inflammatory factors in both groups showed a decreasing trend after treatment. Compared with the control group, IL-6 and HBP in the Xuebijing group significantly decreased on day 7 [IL-6 (ng/L): 66.20 (16.34, 163.71) vs. 79.81 (23.95, 178.64), HBP (ng/L): 95.59 (45.23, 157.37) vs. 132.98 (73.90, 162.05), both P < 0.05]; on day 10, PCT, CRP, IL-6 and HBP significantly decreased [PCT (μg/L): 1.14 (0.20, 3.39) vs. 1.31 (0.68, 4.21), CRP (mg/L): 66.32 (19.46, 115.81) vs. 89.16 (20.52, 143.76), IL-6 (ng/L): 31.90 (13.23, 138.74) vs. 166.30 (42.75, 288.10), HBP (ng/L): 62.45 (29.17, 96.51) vs. 112.33 (58.70, 143.96), all P < 0.05]. ③ Compared with the control group, mechanical ventilation time and the length of ICU stay were significantly shortened and the total hospitalization expenses were significantly reduced in Xuebijing group [mechanical ventilation time (hours): 57.0 (0, 163.5) vs. 168.0 (24.0, 282.0), the length of ICU stay (days): 8.80±4.15 vs. 17.13±7.05, the total hospitalization expenses (ten thousand yuan): 14.55±7.31 vs. 20.01±9.86, all P < 0.05]. There was no significant difference in 28-day mortality and the total hospitalization time [28-day mortality: 37.5% vs. 35.0%, the total hospitalization time (days): 13.05±8.44 vs. 18.30±9.59, both P > 0.05]. ④ Patients were divided into death and survival groups according to the prognosis, and univariate analysis showed that white blood cell (WBC), neutrophil percentage (NEU%), CRP, lactic acid (Lac), APACHEⅡ score, IL-6, HBP were the factors influencing the prognosis of patients. The above indicators were further analyzed by Logistic regression, which showed that CRP, IL-6, and APACHE Ⅱ score were independent risk factors for prognosis [odds ratio ( OR) was 1.007, 1.828, 1.229, all P < 0.05]. Conclusions:Combined with Xuebijing to treat septic shock can reduce the body's inflammatory response to a certain extent, thereby reducing the time of mechanical ventilation, shortening the stay of ICU and reducing the total cost of hospitalization. But it cannot reduce the 28-day mortality of patients with septic shock.

Analysis of risk factors for cervical lymph node metastases in patients with papillary thyroid microcarcinoma / 中国医师进修杂志

Objective To analyze the risk factors for cervical lymph node metastasis in patients with papillary thyroid microcarcinoma (PTMC). Methods The clinical data of 289 patients with PTMC from January 2013 to December 2014 were analyzed retrospectively. All patients underwent thyroidectomy and thyroid isthmectomy/total thyroidectomy plus central (and lateral) cervical lymph node dissection. Results In 289 patients, postoperative pathology confirmed that the central lymph node metastasis was in 118 cases (40.8% ); 64 of them performed central and lateral cervical lymph node dissection, and the rate of lateral cervical lymph node metastasis was 42.2% (27/64). The smooth curve fitting chart showed that the risk of central cervical lymph node metastasis was significantly increased when the tumor diameter ＞ 6 mm. Univariate analysis result showed that central cervical lymph node metastasis was associated with gender, number of primary lesions, unilateral and bilateral tumor, capsule invasion, tumor diameter and Hashimoto thyroiditis (P<0.05 or＜0.01); multivariate Logistic regression analysis result showed that the tumor diameter>6 mm was the independent risk factor for central cervical lymph node metastasis ( OR = 2.036, 95% CI 1.160 - 3.573, P = 0.013). Univariate analysis result showed that lateral cervical lymph node dissection was associated with central cervical lymph node dissection (P<0.05); multivariate Logistic regression analysis result showed that central cervical lymph node dissection was the independent risk factor for lateral cervical lymph node dissection in patients with PTMC ( OR=9.630, 95% CI 1.150-80.628, P=0.037). Conclusions PTMC patients with central or lateral cervical lymph node metastasis is very common, and central lymph node metastasis risk increases significantly when tumor diameter > 6 mm; the risk of lateral cervical lymph node metastasis also significantly increases in patients with central cervical lymph node metastasis.

Objective To explore the effect and adverse reaction of different neoadjuvant chemotherapy regimens:docetaxel + THP + cyclophosphamide and docetaxel + THP in the treatment of triple negative breast cancer.Methods The clinical data of 75 patients with triple negative breast cancer in type Ⅱa-Ⅲc period were retrospectively analyzed.According to different treatment method,they were divided into two groups.The observation group (43 cases)was given the treatment of TAC,the control group (32 cases) was given the treatment of AT.The short-term efficacy and adverse reaction were evaluated and analyzed before every course of treatment,the total effective rate was evaluated after four courses of treatment.The long-term curative effect of the two groups was evaluated by following-up.Results The total effective rate of the observation group was 90.70％,which was significantly higher than 71.88％ of the control group (x2 =4.536,P =0.033).The incidence rates of adverse effects of chemotherapy in the observation group were higher than the control group,but there were no statistically significant differences between the two groups (gastrointestinal disorder x2 =2.931,P =0.087;marrow depression x2 =1.586,P =0.208;baldness x2 =1.367,P =0.242;cardiotoxicx2 =1.114,P =0.291).The three years survival rates in the observation group and the control group were 93.02％ and 87.50％ respectively,there was no statistically significant difference between the two groups(x2 =0.940,P =0.332).Conclusion The neoadjuvant chemotherapy of TAC and AT is both effective in the treatment of triple negative breast cancer,and TAC scheme is superior to AT scheme,the long-term efficacy in the two schemes has no significant difference.

Safety and efficacy of percutaneous patent ductus arteriosus closure via femoral vein under transesophageal echocardiography guidance / 中华实用儿科临床杂志

Objective To investigate the efficacy and safety of percutaneous patent ductus arteriosus (PDA) closure via femoral vein solely under transesophageal echocardiography guidance.Methods From May 2014 to May 2015,28 patients(13 boys,15 girls) were selected in Dalian Children's Hospital Affiliated to Dalian Medical University with PDA closure via the femoral vein under transesophageal echocardiography guidance,with mean age (3.5 ± 2.6)years and mean body weight (16.0 ± 6.5) kg.The mean diameter of PDA was (7.1 ± 3.9) mm.Patients were all treated by percutaneous PDA closure solely by transesophageal echocardiography via the femoral vein.The effect of the procedures was evaluated by echocardiography.The transthoracic echocardiography,chest X-ray film,cardiogram at 1 month,3 months and 6 months after procedure were followed up.Results Twenty-seven cases were successfully treated with percutaneous PDA closure via the femoral vein solely under transesophageal echocardiography guidance,while 1 patient was closed by surgical closure with on-pump beating-heart because PDA occluder strayed into the left pulmonary artery on 1-month follow-up.The procedural time was (48.5 ±8.7) min.The mean diameter of PDA occluder was (8.2 ± 4.1) mm.Twenty-seven patients survived without peripheral vascular injury or complications such as residual shunt,arrhythmia and cardiac perforation.One patient was transformed to surgical closure.Hospitalization time was (2.5 ± 0.5) days.At one month follow-up,no complications such as residual shunt or pericardial effusion occurred.Conclusion Transesophageal echocardiography guided percutaneous PDA closure via the femoral vein approach is safe and effective without the damage from radiation and contrast agents,and aviods the use of femoral artery puncture.

Retrospective analysis of serum C-reactive protein/albumin ratio for the prognosis of the adult patients with sepsis / 中华危重病急救医学

Objective To explore the prognostic value of serum C-reactive protein/albumin (CRP/ALB) ratio in the adult patients with sepsis.Methods A retrospective study was conducted.Clinical data were collected from septic patients who were at least 18 years old and whose intensive care unit (ICU) lengths of stay were at least 3 days,and who were admitted in the Department of Critical Care Medicine of the First Affiliated Hospital of Zhengzhou University in Henan Province from September 2013 to September 2015.These patients were divided into survival group and death group according to 28-day outcome.The serum CRP,ALB,and CRP/ALB ratio levels at the start of treatment (0 hour),24 hours and 72 hours after treatment in ICU were analyzed.And the receiver-operating characteristic (ROC) curve was plotted to assess the value of CRP,ALB and CRP/ALB ratio at different time points for predicting the outcome.Results Sixty-nine patients with sepsis were selected,among whom 28 cases were in the death group and the mortality was 40.6％.The characteristic of the baseline data in the two groups was balanced.The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and sequential organ failure assessment (SOFA) score at the first 24 hours of ICU admission in the death group were significantly higher than those in the survival group (APACHE Ⅱ score:25.18 ± 3.18 vs.17.88±3.20,SOFA score:11.71± 1.78 vs.9.17 ± 2.38,both P ＜ 0.05).And the ICU length of stay in the death group was significantly longer than that in the survival group [days:9.0 (2.5) vs.8.0 (3.0),P ＜ 0.05].The ALB level increased gradually as the treatment was extended in both groups while the levels of CRP and CRP/ALB declined gradually.The ALB levels at 0,24,72 hours after treatment in the death group were significantly lower,and the CRP and CRP/ALB levels were significantly higher than those in survival group [ALB (g/L):23.40 (4.20) vs.25.20 (8.20) at 0 hour,24.18±4.33 vs.28.54±4.88 at 24 hours,25.50±4.88 vs.34.88±7.23 at 72 hours;CRP (mg/L):179.32±34.04 vs.159.55±36.82 at 0 hour,160.08±22.91 vs.146.23±30.31 at 24 hours,159.36±25.81vs.142.53±36.30 at 72 hours;CRP/ALB:7.52±1.32 vs.6.04±1.46 at 0 hour,6.77±1.42 vs.5.23±1.24 at 24 hours,6.40± 1.34 vs.4.19± 1.21 at 72 hours;all P ＜ 0.05].ROC curves analysis showed that the area under ROC curves (AUC) of CRP/ALB at all time points were larger than those of CRP and ALB,with higher sensitivity and specificity;the AUC of ARP/ALB at 0,24,72 hours were 0.767,0.807,0.895,respectively;the cut-off values were 6.96,5.44,4.91,the sensitivity were 71.4％,85.7％ and 89.3％,and the specificity were 73.2％,63.4％ and 82.9％,respectively.Conclusions High serum CRP,CRP/ALB and low ALB in adult patients with sepsis indicate a poor prognosis,while the prognostic value of CRP/ALB is obviously better than the single value of CRP or ALB.CRP/ALB at 72 hours may be one of the best indicators for the assessment of clinical therapy and prognosis of patients with sepsis.
