Objective To investigate the value of extravascular lung water index(EVLWI) in assessment of prognosis of elderly patients with combined septic shock and pulmonary capillary leakage.Methods Totally 34 elderly patients with septic shock and pulmonary capillary leakage in our hospital from Jan.2011 to Dec.2012 were selected.Cardiac index (CI),global end diastolic volume index (GEDI),systemic vascular resistance index (SVRI),pulmonary vascular permeability index (PVPI) and EVLWI were detected by pulse-indicator continuous cardiac output (PiCCO) technology for 3 days.Based on the actual body weight (ABW) and predicted body weight (PBW),the actual extravascular lung water index and predicted extravascular lung water index were calculated.Peak airway pressure (Ppeak),plateau pressure (Pplat),mean airway pressure (Pm),tidal volume (VT),positive end expiratory pressure (PEEP),oxygen concentration (FiO2) and static lung compliance (Cst) were monitored,the arterial partial pressure of oxygen (PaO2) was detected by blood gas analysis,and the PaO2/FiO2 (P/F) and oxygenation index (OI) were calculated.Chest X-ray,lung injury score (LIS) were conducted.The correlations of EVLWI to actual body weight (EVLWIa) and predicted body weight(EVLWIp) with P/F,Cst and LIS were analyzed.The predictive value of EVLWIa and EVLWIp in the prognosis in elderly patients with septic shock and pulmonary capillary leakage was assessed.Results At day 1,non-survivors had higher levels of SOFA score and lactate level than survivors (both P＜0.05).However,these variables including SOFA score,LIS,PVPI,lactate level,fluid balance,norepinephrine level,EVLWIa and EVLWIp were higher and PaO2/FiO2 was lower in non-survivors than in the survivors at day 3 (all P＜0.05).EVLWIa and EVLWIp were positively correlated with LIS (r=0.461 and 0.588,both P＜0.05) and negatively correlated with PaO2/FiO2 (P/F) (r=-0.307 and-0.436,both P＜0.05).EVLWIa and EVLWIp had negatively correlations with Cst,but r=-0.141 and-0.154,both P＞0.05.Multiple logistic regression analysis showed that SOFA,EVLWa and EVLWp were independent predictive risk factors for mortality in elderly patients with septic shock and pulmonary capillary leakage.The areas under the receiver operating characteristic curve (ROC) of SOFA,EVLWIa and EVLWIp for predicting the prognosis were 0.769,0.832 and 0.855 respectively.With 11.96ml/kg as the cutoff point of EVLWIp,the sensitivity and specificity of EVLWIp predicting the survival of patients was 94.4％ and 61.5％ respectively.Conclusions Extravascular lung water can predict the prognosis and reflect the severity of lung injury in elderly patients with septic shock and puhnonary capillary leakage.Compared with EVLWIa,the EVLWIp has a better correlation with lung injury and a higher predictive value for survival.

Objective:To investigate the clinical efficacy and effects on hemorheology of acupuncture therapy combined with gaba-pentin in the treatment of patients with tension headache. Methods:Totally 92 cases of patients with tension headache were randomly divided into the observation group (n=46) and the control group (n=46) according to the random number table. The control group was given gabapentin, while the observation group was treated with acupuncture therapy on the basis of treatment in the control group. The treatment course was 4 weeks. The clinical efficacy, changes of the headache indices, VAS score and hemorheology levels before and after the treatments in the two groups were compared, and the incidence of adverse reactions was observed as well. Results:The to-tal effective rate of the observation group (93. 48%) was significantly higher than that of the control group (73. 91%, P<0. 05). Af-ter the treatment, the headache indices in both groups significantly decreased (P<0. 05), and the decrease in the observation group was more significant than that in the control group (P<0. 05). The VAS scores in both groups significantly decreased after the treat-ment (P<0. 05), and the decrease in the observation group was more significant than that in the control group (P<0. 05). The plas-ma viscosity, hematocrit and platelet aggregation rate in both groups significantly decreased after the treatment (P<0. 05), and the decrease in the observation group was more notable than that in the control group (P<0. 05). No severe adverse reactions were shown in both groups during the treatment course. Conclusion: Acupuncture therapy combined with gabapentin in the treatment of patients with tension headache shows striking effects, which can improve hemorheology with promising safety and deserves further studies.

Objective To evaluate the relationship between the extravascular lung water (EVLW) and other markers of lung injury and determine whether or not EVLW predicts survival in patients with acute respiratory distress syndrome (ARDS) and examine if indexing EVLW with predicted body weight (EVLWp) strengthens its discriminative power.Methods EVLW and other markers of lung injury [including:PaO2/FiO2(P/F),oxygenation index (OI) =mean pressure (Pm) × FiO2 × 100/PaO2,static compliance (Cst) and lung injury score (LIS)] were measured prospectively for 3 days in 27 patients with early ARDS between January 2011 and December 2011 at intensive care units (ICU) of Subei People's Hospital.The relationship between indexing EVLW with actual body weight (EVLWa),EVLWp and other markers of lung injury,the 28-day mortality were evaluated.Results Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ),fluid balance in first 3 days,days of mechanical ventilation and ICU stay were significantly higher on admission in nonsurvivors compared with survivors (P ＜ 0.05).Nonsurvivors had higher OI,LIS,EVLWa and EVLWp than survivors at Days 1 and 3 (P ＜ 0.05).EVLWa and EVLWp were correlated positively with LIS (r =0.471,0.528 P ＜ 0.05) and OI (r =0.527,0.627,P ＜ 0.05) and negatively with P/F (r =-0.467,-0.646,P ＜ 0.05).EVLWp had a stronger correlation to LIS,OI and P/F than did EVLWa.No obvious correlation existed between EVLWa,EVLWp and Cst (r =-0.260,0.226,P ＞ 0.05).ROC curve analysis indicated that EVLWp (0.759,P ＜ 0.05) but not EVLWa (0.661,P＞0.05) discriminated between survivors and nonsurvivors.Three-dav average EVLWp ≥12.5ml/kg predicted the 28-day mortality with 62.5％ specificity and 80％ sensitivity.Conclusion Increased extravascular lung water is a feature of early ARDS and predicts survival.EVLWp,instead of EVLWa,improves the predictive value of extravascular lung water for survival and it is correlated with markers of disease severity.

Objective To evaluate the value of transpulmonary pressure (Ptp) guided optimal positive end-expiratory pressure (PEEP) selection in patients with early acute respiratory distress syndrome (ARDS).Methods A prospective randomized self-control study was conducted.ARDS patients in the early stage (onset ≤3 days) undergoing intubation and mechanical ventilation admitted to intensive care unit (ICU) of Jiangsu Provincial Subei People's Hospital from December 2013 to December 2015 were enrolled.The PEEP level was regulated to 30 cmH2O (1 cmH2O =0.098 kPa) after recruitment maneuver,and then it was gradually decreased to 0 with lowering by 3 cmH2O every 5 minutes.The optimal PEEP was titrated by Ptp,lowest dead space fraction (VD/VT),highest static lung compliance (Cst),and optimal oxygenation,respectively.Parameters of respiratory mechanics and gas exchange were observed.Results Totally 28 patients with ARDS (including 17 male and 11 female) were included with the average age of (45 ± 12) years old,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was 21 ± 9,oxygenation index (PaO2/FiO2) was (165 ± 76) mmHg (1 mmHg =0.133 kPa).① During decremental PEEP titration,Ptp was gradually decreased,and expiratory Ptp (Ptp-e) was more than zero [(1.3±0.3) cmH2O] when PEEP was (9.6 ± 2.3) cmH2O.Cst was initially improved until reaching a peak,and then deteriorated.Cst was highest [(50 ± 8) mL/cmH2O] when PEEP was (11.5 ± 2.4) cmH2O.PaO2/FiO2 reached the maximum [(312 ± 99) mmHg] at PEEP level of (18.0 ± 2.5) cmH2O.Compared with Ptp-e 3.00-5.99 cmH2O,PaO2/FiO2 was significantly decreased when Ptp-e became negative (all P ＜ 0.05).VD/VT was lowest (0.52 ±0.05) when PEEP was (10.1 ± 2.2) cmH2O.When compared with ventilation [inspiratory Ptp (Ptp-i) 0-2.99 cmH2O],it was significantly higher during high (Ptp-i ≥ 15 cmH2O,all P ＜ 0.05).② There were no statistically significant differences in the levels of optimal PEEP,Ptp-i and Ptp-e among Ptp,lowest VD/VT and highest Cst methods (all P ＞ 0.05),but they were significantly less than optimal oxygenation method (all P ＜ 0.05).Compared with baseline and the method of optimal oxygenation,Cst in other three PEEP titration methods including Ptp,lowest VD/VT and highest Cst was improved obviously (mL/cmH2O:46± 7,47±9,50± 8 vs.30± 8,35 ± 10,all P ＜ 0.05).PaO2/FiO2 (mmHg) in the method of Ptp and lowest VD/VT were higher than the baseline (252 ± 86,258 ± 72 vs.165 ± 76,both P ＜ 0.05),but significantly lower than that of optimal oxygenation method (312 ± 99,both P ＜ 0.05),and did not significantly differ from that of highest Cst (268± 85,both P ＞ 0.05).Compared with baseline and the method of optimal oxygenation,VD/Vr improved significantly in ventilated patients on PEEP targeting with Ptp and lowest VD/VT (0.53±0.05,0.52±0.05 vs.0.59±0.05,0.58±0.04,all P ＜ 0.05).Conclusion Titration the optimal PEEP level with the method of Ptp could promote collapse alveolar recruitment,improve oxygenation and lung compliance,decrease dead space ventilation,and will not cause alveolar excessive inflation in patients who undergoing mechanical ventilation with early ARDS.

Objective To investigate the clinical efficacy of ginkgo leaf tablets in patients with forgotten-type mild cognitive impairment (aMCI) and its effect on soluble glycosylated terminal product receptor (sRAGE) and soluble low-density lipoprotein receptor-associated protein 1 (sLRP-1).Methods A total of 124 patients with aMCI were divided into observation group (n =62) and control group (n =62),treated by nimodipine tablets (30 mg) three times a day,ginkgo leaf tablets for 3 times a day,respectively.The changes of MoCA score,levels of sRAGE,sLRP-1 and the occurrence of adverse reactions before and after treatment were compared between the two groups.Results The scores of MoCA were improved in both groups after treatment,and the observation group improved more after treatment,and the differences were statistically significant (P ＜ 0.0 5).There was no significant difference in plasma sRAGE and sLRP-1 levels between the two groups (P ＞ 0.05),but the plasma sRAGE increased and the sLRP-1 level decreased after treatment in two groups (P ＜ 0.05).Plasma sRAGE was higher in the treatment group than that in the control group,while the sLRP-1 level was lower than that in the control group (P ＜0.05).Conclusion Ginkgo leaf tablets have a significant clinical effect for aMCI patients,which can increase level of plasma sRAGE and decrease sLRP-1.

Objective To explore the effect of comprehensive nursing intervention on cognitive function,mental state and the quality of life in patients with Parkinson's disease.Methods Forty patients with Parkinson's disease treated in our hospital were randomly divided into control group and intervention group.The control group was treated with conventional drugs,and the intervention group was given comprehensive nursing intervention on the basis of conventional drug therapy for 6 months.Results The scores of cognitive function,mental state and the quality of life in intervention group were significantly better in the nursing group than control group (P ＜ 0.05).Conclusion Comprehensive nursing intervention has better efficacy,which can not only improve cognitive function,regulate the mental state and improve the quality of life,but also can greatly improve the negative emotions of patients with Parkinson's disease.

Objective: To investigate the value of four-dimensional echocardiography combined with speckle tracking technique on the assessment of right heart function and prognosis in patients with pulmonary arterial hypertension (PAH). Methods: In this prospective study, 51 patients with PAH diagnosed by right heart catheterization in east hospital and south hospital of Renji hospital affiliated to school of medicine of Shanghai Jiaotong University from September 2015 to July 2017 were enrolled as PAH group from July to November 2017. Meanwhile, 26 healthy volunteers with age and sex matched with pulmonary hypertension patients were recruited as control group. The patients were aged (45.8±15.5) years old in PAH group, and there were 6 males and 45 females. The healthy volunteers were aged (45.4±14.6) years old in control group, and there were 4 males and 22 females. Two-dimensional and four-dimensional echocardiographic images were obtained to measure the structure and function of the right heart. The myocardial strain of each ventricle and atrium was measured by sparkle tracking. The patients in PAH group were followed up from July 2017 to August 2018 to observe the endpoint events including all-cause death, re-hospitalization, and clinical deterioration. Results: There were significant differences in two-dimensional echocardiographic parameters(including tricuspid annular plane systolic excursion (TAPSE), right ventricular area change fraction (FAC), and right ventricular systolic pressure (RVSP)), speckle tracking parameters (including global longitudinal systolic peak strain of left ventricle (LVGLS), global longitudinal systolic peak strain of right ventricle (RVGLS),left atrial reservoir function(LASr), left atrial conduit function (LASc), left atrial pump function (LASp), right atrial reservoir function (RASr), right atrial conduit function (RASc), and right atrial pump function (RASp)), and four-dimensional echocardiographic parameters(including right ventricular end diastolic volume (RVEDV) , right ventricular end systolic volume(RVESV), right ventricular stroke volume(RVSV), right ventricular freewall longitudinal strain(RVLSf), interventricular septum longitudinal strain(IVSLS), right ventricular ejection fraction(RVEF)) between control group and PAH group (all P<0.01 or 0.05).Spearman correlation analysis showed that RVEF was correlated with 6-minute walking distance (r=0.540, P<0.001), B-type natriuretic peptide (r=-0.545,P<0.001), New York Heart Association (NYHA) cardiac function classification(r=-0.583, P<0.001), TAPSE(r=0.595, P<0.001), LVGLS (r=-0.461, P=0.001) ,LASc (r=0.453, P=0.002) ,RASc (r=0.532, P<0.001) ,RVESV (r=-0.418, P=0.004) , RVSV (r=0.351, P=0.017) , and IVSLS (r=-0.450, P=0.002) . Pearson correlation analysis also showed that RVEF was correlated with FAC(r=0.579, P<0.001),RVSP (r=-0.442, P=0.002) ,RVGLS (r=-0.521, P<0.001) , LASr (r=0.483, P=0.001) , RASr (r=0.617, P<0.001) , RASp (r=0.513, P<0.001) , and RVLSf (r=-0.592, P<0.001) .After a follow-up of (10.4±2.7) months, there were 4 all-cause deaths, 5 re-hospitalizations and 5 clinical deterioration. Multivariate Cox regression analysis showed that increased RVEF was independent protective factor for end-point events in PAH patients (HR=0.702, P=0.043), and increased RVSP was independent risk factor for end-point events in PAH patients (HR=1.083, P=0.017). The receiver operating characteristic (ROC) curve showed that RVEF and RVSP could be used to predict the end-point events in PAH patients. The area under the curve (AUC) was 0.835(P=0.001) and 0.820(P=0.001), respectively. Conclusions RVEF measured by four-dimensional echocardiography is correlated with right ventricular function parameters measured by two-dimensional echocardiography and can be used to estimate the prognosis of PAH patients. The right atrial and left atrial function assessed by speckle tracking can also reflect the right ventricular function to a certain extent.

Objective:To establish a classification system for the repair band in the subchondral bone origination point in MRI for traumatic osteonecrosis of the femoral head (ONFH) and preliminarily explore the correlation between this classification and the progression of femoral head collapse.Methods:A retrospective analysis was conducted on 73 cases of traumatic ON-FH treated at the Quanzhou Orthopedic-traumatological hospital from January 2000 to December 2019. Among them, there were 46 males and 27 females with an average age of 34.9±8.3 years (range 19-55 years). Clinical and radiological data such as age, gender, side, fracture classification, reduction quality, JIC classification, and bone repair band (BRB) classification were recorded. The progression of traumatic ONFH was assessed using the ARCO staging system, with stages IIIA and IIIB defined as mild collapse and progressive collapse, respectively. The BRB classification was established based on MRI findings, and the inter- and intra-observer consistency of the BRB classification was analyzed using Kappa test. The correlation between the BRB classification and progressive femoral head collapse was analyzed using the Kaplan-Meier survival curve and binary variable Cox regression analysis.Results:According to the BRB classification, 73 cases were divided into type 1 with superficial lesion in 38.4%, type 2 with uncertain lesion in 21.9%, and type 3 with extensive lesion in 39.7%. The inter-observer consistency Kappa value for the BRB classification was 0.798, and the intra-observer consistency Kappa value was 0.896, indicating a high level of consistency. A follow-up of 73 cases (54.8±34.9 months, range 24-165 months) showed a significant correlation between the BRB classification and ARCO staging at the last follow-up (χ 2=37.556, P<0.001), with progression to stages IIIA and IIIB as follows: type 1 had 3 and 1 cases, type 2 had 4 and 1 cases, and type 3 had 14 and 12 cases, respectively. Using the occurrence of progressive collapse (stage IIIB) as the endpoint, the risk of progression to stage IIIB for type 2 was not statistically different from type 1 [ HR=1.766, 95% CI (0.465, 6.702), P=0.403]; the risk of progression to stage IIIB for type 3 was significantly higher than for type 1 [ HR=15.126, 95% CI (4.708, 48.592), P<0.001]. Conclusion:The BRB classification is closely related to the progression of traumatic ONFH and is an independent risk factor for predicting the occurrence of progressive collapse; this classification is helpful for early diagnosis and predicting the progression of collapse and treatment plan decision-making.
