Effect of advanced airway establishment on prognostic evaluation of cardiopulmonary resuscitation quality index during cardiopulmonary resuscitation / 中华急诊医学杂志

Objective:Cardiopulmonary resuscitation quality index (CQI) is based on pulse oximetry plethysmographic waveform (POP), which have been proved able to reflect the peripheral circulation state as good as the quality of chest compression during cardiopulmonary resuscitation (CPR). It has been confirmed that CQI is as good as the partial pressure of end-tidal carbon dioxide (P ETCO 2) in prognostic evaluation of CPR patients. The purpose of this study was to explore whether advanced airway establishment affects the prognostic value of CQI during CPR. Methods:This was a prospective descriptive study. 376 patients receiving CPR were divided into advanced airway group and non-advanced airway group according to whether advanced airway was established, each of which was divided into ROSC (return of spontaneous circulation) group and non-ROSC group according to whether they got ROSC. The changes of CQI and P ETCO 2 during CPR were collected, and the relation of these parameters and the prognosis of patients was analyzed. Results:In advanced airway group, both CQI [(63.3±20.7) vs (49.7±23.8)] and P ETCO 2 [(19.8 (11.4, 31.6) vs 8.8 (3.3, 15.8)] mmHg were statistically different between ROSC group and non-ROSC group ( P <0.05). The cut-off value for these two parameters were 60.4 and 16.3 mmHg respectively. There was no significant difference between the two curves ( P>0.05). In the non-advanced airway group, CQI [(63.0±21.8) vs (42.2±29.0)] were also statistically different between the ROSC group and the non-ROSC group ( P <0.05). The cut-off value of CQI in advanced airway group and non-advanced airway group were 60.4 and 61.1, respectively. And there was no statistical difference between the two curves ( P>0.05). Conclusions:During CPR, CQI can be used to evaluate the prognosis of patients, which is as good as that of P ETCO 2. Establishment of advanced airway does not affect the prognostic evaluation of CQI during CPR.

The role of regulatory T cells in immune dysfunction during sepsis / 世界急诊医学杂志（英文）

@#BACKGROUND: Although regulatory T cells (Tregs) are key to the maintenance of immunologic homeostasis and tolerance, little is known about Treg-mediated immunosuppression in the stage of sepsis. This article aimed to review the current literature on the role of Tregs in the pathophysiology of septic response, attempting to investigate the role of Tregs in immune dysfunction during sepsis. DATA SOURCES: A literature search was conducted in January 2014 using the China National Knowledge Infrastructure and PubMed. Articles on the role of Tregs in immune dysfunction during sepsis were identified. RESULTS: The identified articles indicated that Treg levels can be used for the assessment of the course of sepsis. The inhibition of Treg activity can promote the recovery of immune function. CONCLUSION: Since the mechanism of Tregs is complex during the sepsis, more studies are needed.

A clinical study of rhG-CSF of different dosages in preventing leukopenia after chemotherapy in patients with advanced non-small cell lung cancer / 中国癌症杂志

Background and purpose:Myelosuppression is the most common dose-limiting toxicity of tumor chemotherapy in which leukocytopenia and neutropenia are the most common conditions. Not only are up-titrations of the doses of chemotherapeutic drugs limited, but also normal process of the chemotherapy is affected. Filgrastim-Recombinant Human Granulocyte Colony-Stimulating Factor (rhG-CSF) has the activity of stimulating the formation of granulocyte colony and promoting the growth, proliferation and differentiation of granulocytes which can be signiifcantly effective on leukocytopenia and neutropenia induced by chemotherapy. In this study, we observed the leukogenic effects, toxic and side effects of low, medium, and high doses of rhG-CSF used prophylactically after chemotherapy in patients with advanced non-small cell lung cancer (NSCLC), to explore a rational application strategy for rhG-CSF..Methods:One hundred and twenty six patients with pathologically proved advanced non-small cell lung cancer (NSCLC) under chemotherapy were digitally randomized to A, B and C groups. Filgrastim was given to patients of the three groups 24h after the end of chemotherapy. The dosages are: Group A (low dose): 300 μg of Filgrastim, s.c., qd × 1 day; Group B (medium dose): 300 μg of Filgrastim, s.c., qd × 2 days; Group C (high dose): 300 μg of Filgrastim, s.c., qd × 3 days. Then the signs and symptoms as well as toxic and side effects of Filgrastim after medication were observed.Results:Prophylactic usage of medium and high dosages of rhG-CSF could maintain WBC count at no less than 4.0×109/L in nearly 60% of patients. In patients with Grade III leukopenia, more days were needed for recovery of white blood cell (WBC) count with the low dose, while signiifcantly (P<0.05) less days were needed with the high dose. In view of the dynamic changes of neutrophil(ANC), additioning of the high dose of rhG-CSF after chemotherapy could increase the average level ofANC, notably shortening the duration of lowANC caused by chemotherapy. The incidence of infections was 4.76% for the 126 patients as a whole, 9.52% for the low dose group, and 4.76% for the middle dose group. The patients could tolerate the slight side effects incurred during treatment with Filgrastim.Conclusion:All of the three doses (low, medium, and high) of prophylactic administration of Filgrastim after chemotherapy can promote recoveries of WBCs and neutrophil granulocytes and reduce opportunities of infections. High doses of rhG-CSF can be faster and safer in increasing WBCs and neutrophil granulocytes.

Significance of blood pressure variability in patients with sepsis / 世界急诊医学杂志（英文）

BACKGROUND:This study was undertaken to observe the characteristics of blood pressure variability (BPV) and sepsis and to investigate changes in blood pressure and its value on the severity of illness in patients with sepsis. METHODS:Blood parameters, APACHE Ⅱ score, and 24-hour ambulatory BP were analyzed in 89 patients with sepsis. RESULTS:In patients with APACHE Ⅱ score>19, the values of systolic blood pressure (SBPV), diasystolic blood pressure (DBPV), non-dipper percentage, cortisol (COR), lactate (LAC), platelet count (PLT) and glucose (GLU) were significantly higher than in those with APACHE Ⅱ score ≤19 (P<0.05 ), whereas the values of procalcitonin (PCT), white blood cell (WBC), creatinine (Cr), PaO2, C-reactive protein (CRP), adrenocorticotropic hormone (ACTH) and tumor necrosis factor α(TNF-α) were not statistically significant (P>0.05). Correlation analysis showed that APACHE Ⅱ scores correlated significantly with SBPV and DBPV (P<0.01, r=0.732 and P<0.01, r=0.762). SBPV and DBPV were correlated with COR (P=0.018 and r=0.318; P=0.008 and r=0.353 respectively). However, SBPV and DBPV were not correlated with TNF-α, IL-10, and PCT (P>0.05). Logistic regression analysis of SBPV, DBPV, APACHE Ⅱ score, and LAC was used to predict prognosis in terms of survival and non-survival rates. Receiver operating characteristics curve (ROC) showed that DBPV was a better predictor of survival rate with an AUC value of 0.890. However, AUC of SBPV, APACHE Ⅱ score, and LAC was 0.746, 0.831 and 0.915, respectively. CONCLUSIONS:The values of SBPV, DBPV and non-dipper percentage are higher in patients with sepsis. DBPV and SBPV can be used to predict the survival rate of patients with sepsis.

Association of interleukin-6 promoter polymorphism with knee osteoarthritis: a meta-analysis / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Osteoarthritis (OA) is the most common form of human polyarthritis. Many genetic factors have been implicated in OA. It was reported that a polymorphism in the gene of interleukin-6 (IL-6) was associated with OA of knee. The aim of this study was to determine whether functional IL-6 promoter -174G/C (rs1800795) polymorphisms confer susceptibility to knee OA.</p><p><b>METHODS</b>A meta-analysis was conducted on the association between the IL-6 polymorphism and knee OA. Electronic search at PubMed, EMBASE, Weipu database, and Wanfang database was conducted to select studies. Case-control studies containing available genotype frequencies of IL-6 -174G/C were chosen, and odds ratio (OR) with 95% confidence interval (CI) was used to assess the strength of this association.</p><p><b>RESULTS</b>A total of seven studies involving 6 464 subjects (knee OA 3 331 and controls 3 133) were considered in this study. The results suggested that the variant genotypes were not associated with knee OA risk in all genetic models (additive model: OR = 1.144, 95% CI 0.934-1.402, P = 0.194; recessive model: OR = 1.113, 95% CI 0.799-1.550, P = 0.526; dominant model: OR = 1.186, 95% CI 0.918-1.531, P = 0.191). A symmetric funnel plot, the Begg's test (P > 0.05), suggested that the data lacked publication bias.</p><p><b>CONCLUSIONS</b>This meta-analysis does not support the idea that rs1800795 genotype is associated with increased risk of knee OA. However, to draw comprehensive and more reliable conclusions, further prospective studies with larger numbers of participants worldwide are needed to examine the association between rs1800795 polymorphism and knee OA.</p>

Clinical study of lobaplatin combined with vinorelbine for non-small cell lung cancer / 中国癌症杂志

Background and purpose. Chemotherapy is a standard treatment for patients with advanced stage non-small cell lung cancer (NSCLC) However, platinum based chemotherapeutic regimen haves high toxicity profile to normal tissues. Lobaplatin (LBP) is a new third-generation antitumour platinum drug. Studies abroad have shown that Iobaplatin has an anticancer activity similar to cisplatin with better tolerance and is more effective for those who are resistant to cisplatin. This study was aimed to observe the effectiveness and toxicities of lobaplatin combined with vinorelbine (NVB) for the treatment of advanced NSCLC. Methods: Sixty-four patients pathologically diagnosed as clinical stage Ⅲ_B-Ⅳ NSCLC who did not receive treatment before, were randomly assigned to two groups. NL group (NVB+LBP): LBP at a dose of 30 mg/m~2 intravenous infusion on day 1, and NVB at a dose of 25 mg/m~2 intravenous infusion on days 1 and 8. NP group (NVB+DDP): Cisplatin (DDP) at a dose of 30 mg/m~2 intravenous infusion on day 1, 2 and 3 and NVB at a dose of 25 mg/m~2 intravenous infusion on days 1 and 8. Treatments were repeated every 21-28 days for 3 cycles. Results: For 34 patients of NL group, there were CR (1 cases), PR(13 cases), NC(15 cases), and PD(5 cases). The overall response rate (RR) was 41.2%, disease control rate (DCR) was 85.3%. In NP group: RR was 43.3%, DCR was 83.3% (X~2=0.05, P>0.05). Median overall survival time was 8.6 months and 8.9 months for NL group and NP group, respectively. The main toxicities in NL group were myelosuppression. Digestive toxicity such as anorexia, nausea,vomiting were less than those in the NP group (X~2=7.43, P<0.05), Peripheral hour,toxicity, serious liver and renal toxicity were not observed in NL group. Conclusion: Compared with cisplatin plus vinorelbine, domestic lobaplatin with vinorelbine yielded similar efficacies for NSCLC, but had less toxicity and well tolerate.
