Objective To investigate the prognostic effects of continuous renal replacement therapy on multiple organ dysfunction complicated with acute kidney injury.Methods Fifty nine patients who were diagnosed with multiple organ dysfunction syndrome (MODS) complicated with acute kidney injury (AKI) and underwent continuous renal replacement therapy (CRRT) were selected and grouped according to the Kidney Disease Improving Global Outcomes (KDIGO) staging.Their clinical data before CRRT were collected.The patients were grouped according to the Intensive Care Unit (ICU) prognosis,namely death and survival.The differences between two groups were analyzed.The multinomial logistic regression analysis was performed to explore the prognostic factors.Results With the increase of KDIGO stage,the Acute Physiology And Chronic Health Evaluation Ⅱ (APACHEII) score,Sequential Organ Failure Assessment (SOFA) score,the need for vasoactive drugs,and the number of cases with oliguria and ICU mortality rates showed an increasing trend,and those differences were statistically significant (P ＜ 0.05).After multivariate analysis,KDIGO Ⅲ stage,the number of failed organs,oliguria,and the mean daily fluid balance were independent risk factors of death in patients who were diagnosed with MODS complicated with AKI and underwent CRRT.Conclusions The KDIGO classification plays an important role in predicting the prognosis of patients with MODS complicated with AKI in need of CRRT.The number of failed organs,oliguria,and the mean daily fluid balance are also the risk factors for prognosis.

Objective To detect the levels of high mobility group box 1 protein HMGB1),tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6),C-reactive protein (CRP) in order to explore the clinical significance of HMGB1 in patients with severely traumatic brain injury.Methods A total of 75 patients composed of 40 male and 35 female with severely traumatic brain injury were hospitalized from March 2011 through March 2012.The scores of Glasgow Coma Scale (GCS) were 5-8 within 12 hours after brain injury.Casualties with history of hypertension,diabetes,severe diseases of heart,liver and kidney,and with concurrent trauma of other parts of body were excluded.Another 50 healthy subjects were enrolled as controls.Serum samples were taken from both patients and controls at admission.The levels of HMGB1,TNF-α and IL-6 were measured by using enzyme-linked immunosorbent assay (ELISA).The level of CRP was measured by using automatic biochemistry analyzer.Comparisons of the levels of HMGB1,TNF-α,IL-6and CRP between casuahies and healthy controls were carried out.The correlations of HMGB1 with TNF-α,IL-6,CRP in patients with severe traumatic brain injury were analyzed.Thereafter,75 patients were divided into two groups post hoc:the death group and the survival group.On the 1st day,the 3rd day and the 7th day after trauma,serum HMGB1 was detected.The comparison of HMGB1 was made between death group and survival group by using t-test.Results Serum HMGB1 level in the traumatic patients was higher than that of healthy controls (P ＜ 0.01).Correlative analysis showed that there was a positive correlation between HMGB1 and TNF-α (r =0.365,P＜0.05),IL-6 (r=0.530,P＜0.05),CRP (r=0.661,P＜0.05) in patients with severe traumatic brain injury.Serum HMGB1 level in the death group was higher than the survival group (P ＜ 0.01).Conclusions Increased serum HMGB1 level was found after severe traumatic brain injury.There were positive correlations between HMGB1 and three inflammatory factors,TNF-α,IL-6and CRP.Serum HMGB1 should be used as reliable hiomarker to judge the prognosis of patients with severe traumatic brain injury.

A total of 105 patients with ketosis-onset diabetes were divided into four groups (A+B-,A + B +,A - B -,A - B +) based on the results of islet-associated autoantibodies (A +,A - ) and β-cell function (B +,B - ).Nearly 94％ patients in the A -B + group and 1/10 patients in the A - B - group were non-insulin dependent.While in the A + B - and A + B + groups,the detection rates of subsequent non-insulin dependency were 20％ and 58％,respectively.Among the four groups,patients in the A - B + groups had a lower level of IL-6 and a higher level of TNF-α. Patients in the A + B - and A + B + groups had a higher level of IL-18.Our study indicates that patients with ketosis-onset diabetes may present different clinical characteristics. Evaluate the islet-associated autoantibodies and pancreatic β-cell function may be helpful to the clinical diagnostic and therapeutic strategies in diabetes.

Objective To observe blood gas analysis of internal carotid artery and internal jugular vein to calculate the cerebral extraction of oxygen, and to investigate the relationship between oxyhemoglobin in internal jugular vein, cerebral extraction of oxygen, and the prognosis of patients with head injury. Method Seventy patients with acute severe head injury in ICU of Taizhou People Hospital were studied, and another 80 patients with mild head injury were enrolled as controls. Twenty-four hours after first aid such as keeping airway open and circulatory and ventilation support, and emergency craniotomy, the blood samples from internal carotid artery and internal jugular vein were collected for blood gas analysis including SaO2, PaO2, SjvO2, PJVO2 > PaCO2, PJVCO2, SaO2-SjvO2, Pa-jvCCO2, CaO2-CjvO2 and Ca-jvO2/CaCO2 (CEO2, cerebral oxygen extraction). Results There were significant differences in SjvO2, PjvO2, Sa-jvO2, Pa-jvO2 Ca-jvO2 and CEO2 between two groups. Conclusions The SjvO2 and CEO2 represent the cerebral oxygen uptake and oxygen consumption precisely, and they can be used to predict the outcome of patients with severe craniocerebral trauma commendabiy.

Objective To investigate the changes and the clinical significance of serum concentration of soluble Fas (sFas) and Fas ligand (FasL) in the elderly. Methods Fifty elderly subjects and forty-seven adults were recruited. Serum concentration of sFas and EasL were detected by enzyme-linked immunosorbent assay (ELISA) . Psychosocial stress and coping styles were also evaluated. Results The sFas level of the elderly was significantly higher than that in control group,whereas the EasL level was decreased with ageing (P<0.01). A positive correlation between sFas level and psychosocial stress, and a negative correlation between sFas level and positive coping were also found (all P<0. 05). Conclusions Age-related changes occur in serum sEas and EasL levels.The interaction of sFas/FasL system with psychosocial stress and coping styles seems to play important roles in immunosenescence. Our results also suggest that during aging a subtle balance between sFas and FasL could exist.

Objective To study the effects of high volume hemofiltration (HVHF) according to pulse-indicated continuous cardiac output (PiCCO) on patients with acute respiratory distress syndrome (ARDS).Methods A prospective randomly controlled trial was conducted.163 patients with ARDS admitted to Taizhou People's Hospital,Medical College,Nantong University,between February 2011 and January 2014,were enrolled.The patients were randomly divided into conventional therapy group (n＝ 50),HVHF group (n =55),and PiCCO + HVHF group (n＝58) by random number table.The patients in conventional therapy group received routine treatment including mechanical ventilation and drug treatment according to ARDS treatment guideline.The patients in the HVHF group received HVHF treatment of 18 hours per day on 1,3,5,7 days on the basis of conventional therapy.Patients in the PiCCO + HVHF group received HVHF treatment according to PiCCO.The indexes of lung function and PiCCO monitoring were recorded at intensive care unit (ICU) admission (before) and 4 days and 7 days after treatment.The serum levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were determined by enzyme linked immunosorbent assay (ELISA),and the prognosis of patients was recorded.Results In three groups,oxygenation index (PaO2/FiO2),static lung compliance (Cs) were gradually increased,and respiratory rate (RR),lactic acid (Lac) were gradually decreased.The indicators in HVHF and PiCCO + HVHF groups were significantly improved compared with conventional therapy group.The indexes in PiCCO + HVHF group were significantly increased or decreased compared with those in HVHF group,and the statistical differences were found on the 7th day after treatment [PaO2/FiO2 (mmHg,1 mmHg=0.133 kPa):189.3 ± 36.8 vs.166.3 ± 36.1,Cs (mL/cmH2O):76.7 ± 18.9 vs.67.0 ± 18.2,RR (times/min):16.4 ±5.2 vs.19.2 ± 5.4,Lac (mmol/L):1.20 ±0.41 vs.1.41 ±0.43,all P＜0.01].In PiCCO +HVHF group,cardiac index (CI) was gradually increased,and extra vascular lung water index (EVLWI) and intra thoracic blood volume index (ITBVI) were gradually decreased.There were significant differences in the indexes 4 days and 7 days after treatment compared with those before treatment [CI (L·min-1·m-2):4.62 ± 1.13,4.83 ± 1.10 vs.4.01 ± 1.02,EVLWI (mL/kg):7.6 ± 2.7,6.5 ± 2.6 vs.12.4 ± 2.9,ITBVI (mL/m2):801.3 ± 120.9,785.4 ± 118.7 vs.980.1 ± 168.6,all P＜0.01].After treatment,the serum levels of TNF-α and IL-1β in three groups were gradually decreased.Compared with the conventional therapy group,the serum levels of TNF-α and IL-1β on 4 days and 7 days in the HVHF and PiCCO + HVHF groups were significantly decreased,and the statistical differences were found on 7 days [TNF-α (ng/L):68.35 ± 12.63,67.54 ± 12.90 vs.85.35 ± 13.70; IL-1β (ng/L):424.6 ± 142.9,412.2 ± 140.2 vs.895.2 ± 187.7,all P＜0.01].Compared with the HVHF group,the serum levels of TNF-α and IL-1β in the PiCCO + HVHF group were slightly decreased without statistical differences.Compared with the conventional therapy group,the number of organ failure,duration of mechanical ventilation,the length of stay in ICU and hospital mortality in HVHF group and PiCCO + HVHF group were lowered,and the statistical differences were found in PiCCO + HVHF group compared with HVHF group [number of organ failure:2.41 ± 0.79 vs.2.72 ± 0.80,duration of mechanical ventilation (days):4.8 ± 2.0 vs.5.7 ± 2.1,the length of stay in ICU (days):11.5 ± 3.4 vs.13.1 ± 3.6,hospital mortality:31.0％ (18/58) vs.41.8％ (23/55),all P＜0.05].Conclusions Levels of inflammatory factors in patients with ARDS could be reduced by HVHF.The oxygenation and compliance of lung can be improved,the number of organ failure can be lowered,the duration of mechanical ventilation and the length of stay in ICU can be shortened,and the hospital mortality could be declined by PiCCO guided HVHF.

Objective:To investigate the prevalence, risk factors and outcomes of diastasis recti abdominis (DRA) in multiparas after the second delivery.Methods:From June 2017 to September 2019, 300 multiparas with an average age of (31.7±4.0) years (26 to 43 years) after the second delivery were recruited at 6 weeks postpartum from two hospitals in Wenzhou. There were 171 multiparas with two natural births,36 multiparas with one natural birth and one caesarean delivery, and 93 multiparas with two caesarean deliveries. The interrectus distance (IRD) was measured with palpation at 6 weeks, 6 months and 12 months after delivery. Data on age, height, weight before pregnancy and delivery, baby′s birth weight, abdominal circumference before pregnancy and delivery, fetus number, delivery mode and occupation type were collected. Strength and endurance of abdominal muscle was assessed using manual muscle testing and curl-ups, low back pain was assessed using Oswestry disability index(ODI), urinary incontinence was assessed with International Consultation on Incontinence guestionnaire-incontinentia urinae (ICIQ-UI) short form (ICIQ-SF), and quality of life was assessed using 36-item short form health survey (SF-36).Results:Prevalence of DRA was 51.7%(155/300), 39.3%(116/295) and 27.7%(80/289) 6 weeks, 6 months and 12 months after delivery, respectively. Logistic regression analysis indicated that age ( OR=1.39, 95 %CI:1.02-1.91, P=0.38), abdominal circumference ratio ( OR=2.31, 95 %CI:1.23-4.33, P=0.01), twins ( OR=11.41, 95 %CI:2.15-60.76, P<0.01), and cesarean section ( OR=1.44, 95 %CI:1.06-1.95, P=0.02) were the risk factors of DRA at 12 months after delivery. At 12 months after delivery, the multiparas with DRA had weaker strength and endurance of abdominal muscle ( Z=-3.62, P<0.01; Z=-8.91, P<0.01), more serious low back pain ( Z=-2.10, P=0.04), and lower quality of life on physical health ( t=-3.34, P<0.01) than the multiparas without DRA. No difference in prevalence and severity of urinary incontinence and quality of life on psychological health was found when comparing multiparas with and without DRA (χ 2=0.66, P=0.42; Z=-1.18, P=0.24; t=0.91, P=0.36). Conclusion:Multipara after the second delivery has great likelihood for DRA.Age, abdominal circumference ratio, twins, and cesarean section are the risk factors of DRA. DRA is related to abdominal muscle dysfunction, low back pain, and quality of life.
