Objective:To develop and verify a nomogram to predict disease-free survival(DFS)and overall survival(OS)for patients undergoing cervical cancer surgery,which may provide reference for evaluating the prognosis of cervical cancer patients undergoing surgery.Methods:The clinical,pathological and follow-up data of patients who underwent radical operation for cervical cancer in Xijing Hospital,Air Force Medical University from March 2013 to October 2018 were analyzed retrospectively.Based on Cox regression analysis,Bayesian Informa-tion Criterion(BIC)backward stepwise selection method and R square screening variables,Net Reclassification Index(NRI)and Integrated Discrimination Improvement(IDI)were used to compare the predictive efficiency of the model,and a nomogram with better predictive efficiency was selected.The consistency index(C-index)and the receiver operating characteristic curve(ROC)were used to test the efficiency of the nomogram.Results:A total of 950 patients with cervical cancer were enrolled in this study.The risk factors for constructing the DFS nomogram were FIGO stage(2018),parametrium invasion,invasion depth,and maximum tumor diameter.The C-index for DFS in the training cohort and the verification cohort were 0.754 and 0.720,respectively.The area under ROC of the training cohort for 1-,3-and 5-years was 0.74(95%CI 0.65-0.82),0.77(95%CI 0.71-0.83)and 0.79(95%CI0.74-0.85),and the areas under ROC of verification cohort 1-,3-and 5-years were 0.72(95%CI 0.58-0.87),0.75(95%CI 0.64-0.86)and 0.72(95%CI 0.61-0.84),respectively.The risk factors for con-structing the OS nomogram were FIGO stage(2018),histological type,LVSI,parametrium invasion,surgical mar-gin,and invasion depth.The C-index for OS in the training cohort and the verification cohort were 0.737 and 0.759,respectively.The area under ROC of the 3-and 5-year training cohort were 0.76(95%CI 0.69-0.83)and 0.78(95%CI 0.72-0.84),and the areas under ROC of verification cohort 3-and 5-years were 0.76(95%CI 0.65-0.87)and 0.79(95%CI 0.69-0.88),respectively.Conclusions:This study is based on real-world big data to construct nomogram of DFS for 1,3,and 5 years and OS for 3,and 5 years for cervical cancer,which have ideal predictive effects and help clinical physicians correctly evaluate the prognosis of cervical cancer surgery patients.It provides strong reference basis for diagnosis,treatment,and prognosis evaluation.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.

Objective To investigate the current situation of treatment and control of hypertension among the elderly in Jiang^’an District of Wuhan, and to analyze the relationship between body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR) and the treatment and control of hypertension. Methods A random sampling method was used to recruit 17,749 hypertension patients aged 65 and above who participated in free physical examinations for the elderly in Jiangan District. Relevant information was collected through questionnaire surveys and physical examinations in 2018. Logistic regression analysis was conducted to analyze the correlation between BMI, WC, WHtR and the treatment and control rate of hypertension. Results Among all elderly hypertension patients included in this study, 12,379 (69.74%) reported the treatment of hypertension, of which 6,055(48.91%) had their high blood pressure under control. After adjusting factors such as gender, age, and education level, etc., obesity (OR=1.698), central obesity (OR=1.445), and abnormal WHtR (OR=1.421) were the protective factors of the treatment of hypertension. Overweight (OR=0.843), obesity (OR=0.762) and high WHtR（OR=0.889）reduced the control rate of hypertension. There was no significant relationship between abdominal obesity and blood pressure control. Conclusion Overweight，obesity and high WHtR are the risk factors of hypertension control in the elderly. Weight management can therefore be a takeaway as a key intervention measure for hypertension management in the elderly.

Objective To study in the correlation of the laboratory markers of coagulation,fibrinolysis and thrombosis in patients with sepsis and SOFA score,the procalcitonin (PCT) concentration and seven-day survival rate.Methods From February 2017 to March 2018,119 patients with sepsis admitted in ICU and another 119 patients with non-sepsis undergoing selective surgery were enrolled as control in this study.APTT (activated partial thromboplastin time),PT-INR (prothrombin time-international normalized ratio),FIB (fibrinogen),AT-Ⅲ (antithrombin Ⅲ),D-Dimer,FDP (fibrinogen degradation products),sTM (soluble thrombomodulin),TAT (thrombin antithrombin complex),PIC (plasmin-a2 plasminogen inhibitor complex) and t-PAI-C (tissue plasminogen activator and its inhibitor complex),were simultaneously monitored at admission.The correlation between the given laboratory markers mentioned and SOFA score,the PCT concentration and seven-day survival rate were analyzed with the Spearman correlation analysis.Results (① In the patients with sepsis,a positive correlation between SOFA score and sTM,t-PAI-C,TAT respectively was found,and a negative correlation between SOFA score and PLT (platelet count) was observed,and no correlation between SOFA score and PIC was noticed.(②) A positive correlation between PCT and sTM,t-PAI-C respectively was significant,a negative correlation between PCT and PLT was marked,and no correlation between PCT and AT-Ⅲ,TAT,PIC respectively was found.(③) A negative correlation between seven-day survival rate and sTM,t-PAI-C and TAT respectively was obvious,a positive correlation between seven-day survival rate and AT-Ⅲ,PLT respectively was occurred,and no correlation between seven-day survival rate and PIC was determined.Conclusions Soluble thrombomodulin (sTM),thrombin-antithrombin (TAT),antithrombin Ⅲ (AT-Ⅲ) and tissue plasminogen activator inhibitor complex (t-PAI-c) were good clinical monitoring indicators of coagulation disorder in patients with sepsis,which were the representative of the endothelial cell damage with highly activated coagulation,relatively insufficient anti-coagulation function and poor fibrin degradation ability.These were good adjuvants to PLT,INR and APTT for core diagnostic criteria of coagulation disorder in sepsis.

BACKGROUND: An increasing number of publications are drawing attention to the associations between six common polymorphisms in HOX transcript anti-sense RNA (HOTAIR) and the risk of cancers, while these results have been controversial and inconsistent. We conducted an up-to-date meta-analysis to pool eligible studies and to further explore the possible relationships between HOTAIR polymorphisms (rs920778, rs7958904, rs12826786, 4,759,314, rs874945, and rs1899663) and cancer risk. METHODS: A systematic retrieval was conducted up to 1 July 2017 in the PubMed, Web of Science, and CNKI databases. Eighteen eligible publications including 45 case-control studies with 58,601subjects were enrolled for assessing the associations between the 6 polymorphisms in HOTAIR and cancer risk. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were analyzed to reveal the polymorphisms and susceptibility to cancer. All the statistical analyses were performed using STATA 11.0 software. RESULTS: The pooled analyses detected significant associations between the rs920778 polymorphism and increased susceptibility to cancer in recessive, dominant, allelic, homozygous, and heterozygous models. For the rs7958904 polymorphism, we obtained the polymorphism significantly decreased susceptibility to overall cancer risk among five genetic models rather than recessive and homozygous models. For the rs12826786 polymorphism, we identified it significantly increased susceptibility to cancer risk in all genetic models rather than heterozygous models. However, no significant association was found between the rs1899663, rs874945, and rs4759314 polymorphisms and susceptibility of cancer. CONCLUSION These findings of the meta-analysis suggest that HOTAIR polymorphism may contribute to cancer susceptibility.

Objective To investigate the clinical effect of magnesium sulfate combined with nifedipine in the treatment of patients with pregnancy induced hypertension( HDCP) .Methods Retrospective study was used in this study and 116 patients with HDCP from January 2013 to July 2015 in department of obstetrics and gynecology from our hospital were divided into two groups, including routine group of 62 patients who received routine treatment +magnesium sulfate) and combination group of 54 patients who received routine treatment +magnesium sulphate +nifedipine.The clinical effect was analyzed after five days’ continuous treatment.Results The systolic blood pressure, diastolic blood pressure,24h urinary protein, random urine protein /creatinine,serum homocysteine (Hcy) and CRP values in combination group were lower than routine group (P<0.05).There were no statistical difference in maternal uterine inertia, neonatal asphyxia, fetal distress, postpartum hemorrhage rate between the two groups after the treatment.But the rate of cesarean section in the combination group(50.00%)was significantly lower than that in the routine group(68.25%)(P <0.05).Conclusion Magnesium sulfate combined with nifedipine in the treatment of patients with HDCP had better antihypertensive effect, and would not increase fetal adverse birth outcomes incidence and significantly reduce the rate of cesarean section.

Objective To investigate the lesionsin theleft thalamus and to explore their correlation with executive functionin patients with subcortical ischemic vascular disease(SIVD)by using 1H magnetic resonance spectroscopy (1H-MRS) and diffusion tensor imaging (DTI). Methods Fourteen patients with vascular dementia (VaD), 14 patients with vas-cular cognitive impairment without dementia(VCIND)and 14 normal controls (NC) were recruited. The quantitative analy-sis of N-acetylaspartate (NAA), Choline (Cho), myoinositol (MI) and Creatine (Cr) resonance signals in region of interests (ROI) in the left thalamus were measured. Fractional anisotropy (FA) and mean diffusivity (MD) values in the same region were examined by using DTI. The relationship were analyzedamong the MRS, DTI ratios and cognitive impairment reflect-ed in MMSE and trail making test(TMT). Results The NAA/Cr ratio showed a gradual decrease in the left thalamus of VaD andVCIND patients compared with controls(F=3.656, P=0.038). There was no significant difference in NAA/Cr ra- tiobetween VaD and VCIND patients.Compared with controls, patients with VaD and VCIND demonstrated increased MD value in the left thalamus(F=3.882, P=0.030).There was no significant difference in MD value between VaD and VCIND patients (P>0.05). There were no correlations between NAA/Cr, MI/Cr, Cho/Cr value and DTI parameters in the ROI (P>0.05). TMTb time was positively associated with Cho/Cr(r=0.520,P=0.001 ) and with MD value in the left thalamus (r=0.305, P=0.044). Conclusions Combination of 1H-MRS with DTI can provide the valuable informationon the potential lesions in the thalamus in patients with SIVD. The Cho/Cr and MD values in the leftthalamus may be correlated with ex-ecutive function.

OBJECTIVETo study the intestinal absorption mechanism of traditional Chinese medicine monomer syringopicroside in rats.

METHODThe in situ rat single-pass intestinal perfusion model was established to detect the concentration of syringopicroside by HPLC. The absorption at different intestine segments in rat and the influence of concentration, pH and P-glycoprotein inhibitors of the drug solution on the absorption of syringopicroside were also observed.

RESULTThe absorption rate constant (K,) of syringopicroside at duodenum, jejunum, ileum, and colon were 0.00255, 0.00630, 0.00900, 0.00799 min- , respectively; Ka from intestine at syringopicroside concentration of 0.090, 0.180, 0.360 g x L(-1) were 0.00370, 0.00708, 0.00694 min(-1), respectively; and Ka at pH of 7.4, 6.8 and 5.0 were 0.00733, 0.00747, 0.00362 min(-1), respectively. P-glycoprotein inhibitor on the intestinal absorption of syringopicroside showed significant influence (P < 0.05).

CONCLUSIONSyringopicroside is well absorbed at the lower small intestine. When the drug concentration is low, the absorption rate constant is low, where as Ka increases at medium and high concentrations; the Ka is low at pH 5.0 and increases at pH 6.8 and pH 7.4. Syringopicroside is proved to be a substrate of P-glycoprotein.
