Methods: We randomly divide the 80 mastopathy patients into two groups ,40 patients ac-cepted the 5- Fu local injection (experiment group),and 40 patients taken orally rubixiaopian and ta-moxifen(control group). The clinical effects of the breast pain and breast lump were observed. Re-sults: The total effect of 5- Fu local injection into the lump of the mastopathy patients was 92.5 % , while control group was 75.0% , its difference was significant(P0.05)in the treatment of mastopathy lump. Conclusion: 5- Fu local injection had obvious effects to breast pain and breast lump of mastopathy.

ObjectiveThe pre-hospital data of 839 emergency patients who were admitted to Naxiang Emergency Center of Shanghai from Dec 11 2006 to Jun 11 2007 were analyzed.The first five causes of emergency call were trauma,diseases of newborns,neuron-system diseases.eardio-vascuIar diseases and digestive diseases.The epidemiological data including gender,age of patients,distance to emergency site,duration of ambulance dispatch,results of first aid.etc were also presented in the paper.These data would be helpful for improving pre-hospital medical care of emergency patients.

Objective: To explore the alternatives for T-tube placement in surgical treatment of bile duct stones.Methods: Fourty-nine patients with bile duct stones have been performed retrograde transhepatic biliary drainages(RTBD)since 1991.Among them,37 cases were placed the drainage tubes through the right hepatic lobes by retrograde punctures;the other 12 cases with intrahepatic stones were placed the drainage tubes through the intrahepatic bile duct stumps following partial hepatectomies.All the CBD exploration incisions were primarily closed.Results: (1)RTBD by retrograde puncture:Two postoperative complications(5.4%,pneumothorax and biliary hemorrhage)occured.Both cases were cured by medical therapy.The drainage tubes were removed on the 8th postoperative day.(2)RTBD through intrahepatic ducts:Four cases had residual stones(30%)which had been cleared up by combination of extraction and intraluminal lithotripsy.Nineteen cases(38.8%)had the gallbladders preserved.Postoperative cholangiographies showed that all the gallbladders were smooth and well-filled and the extrahepatic bile ducts were in normal shapes.Extrahepatic bile ducts and all the preserved gallbladders did not show any deformity and stone formation by ultrasonography during 6 months to 9 years'following-up.Conclusion: RTBD by retrograde puncture has the advantage of shorter period of bearing drainage tubes;RTBD through intrahepatic duct stump after partial hepatectomy makes it easier to extract postoperative residual stones.Both methods have no negative impacts on the anatomies of both the extrahepatic bile duct and the gallbladder.

Objective To explore the significance of the plasma procalcitonin (PCT) level for directing antibiotic therapy in elderly patients with ventilator-associated pneumonia (VAP).Methods The 50 elderly patients with VAP were randomly separated into the regular therapy group and the PCT-directed therapy group. The regular therapy group was given regular antibiotic therapy, while the antibiotic therapy was decided according to the plasma level of PCT in the PCT-directed therapy group. The used time and utilization rate of antibiotics, as well as inflammatory indicators including white blood cells, neutrophils, C-reactive protein (CRP) and clinical pulmonary infection score (CPIS) were compared between the two groups. Results After treatment, there were no significant differences in white blood cells, neutrophils and CRP between the PCT-directed therapy group and regular therapy group [(8.9 ± 3.5 ) × 109/L vs. (9.4 ± 3.7) × 109/L, 0.62 ± 0.04 vs.0.60±0.04, (18.7±8.5) mg/Lvs. (21.6±6.0) mg/L, t=0.47, 1.84 and 1.37, allP＞0.05],but the CPIS was markedly lower in PCT-directed therapy group than in regular therapy group [(4.0± 1.4) scores vs. (4.7± 1.0) scores, t= 2. 18, P＜0.05]. The neutrophils, CRP and CPIS were significantly lower after treatment than before in the both groups. The concentration of PCT was decreased after treatment than before [(0.5 ± 0.9) mg/L vs. (1.7 ± 0.7) mg/L]. Meanwhile, the time using antibiotics was longer in regular treatment group than in PCT-directed therapy group [(8.72±1.32) d vs. (5.17±0.72) d, t=11.96, P＜0.01], the utilization rate of antibiotics was higher (95.2 % vs. 55.2 %, χ2 = 12.41, P＜0.01) in regular treatment group. Conclusions Using PCT levels for directing treatment in elderly patients with VAP can achieve better curative effect and reduce the use of antibiotics.

Objective To evaluate the predictive value of brain natriuretic peptide (BNP) on mortality in elderly patient with severe sepsis or septic shock. Method Eighty-three elderly patients meeting with criteria of severe sepsis or septic shock by the American College of Chest Physicians and the Society of Critical Care Medicine (ACCP/SCCM) in 2001, admitted in Intensive Care Unit (ICU) of Zhejiang Hospital during May 2004 to June 2007, were enrolled, and patients with chronic renal failure were excluded. The patients were divided into survivor and non - survivor group according to whether they survived within 28 days staying in ICU, the difference of plasma BNP level,serum C-creative protein (CRP) concentration, APACHE II and SOFA scores on admission day and BNP level on the third day between the two groups were compared; thereafter, the relationship between muhiple variables including age, admission day, BNP, CRP, APACHE 11 and SOFA scores, the 3rd day BNP level and 28-day mortality were analyzed by Logistic regression, and meanwhile the independent predictors for ICU moaality among which were determined. Results BNP levels on both admission day and the 3rd day were significantly higher in nomurvivor group than those in survivor group[ ( 1056.38±676.34) pg/ml vs. (611.59±610.02) pg/ml,p =0.002 and (1448.48+891.11) pg/ml vs. (522.41±575.20) pg/ml, P<0.001, respectively]. By Logistic regression analysis, BNP level on the 3rd day and SOFA score on admission day were independent predictors of ICU mortality, The receiver operating characteristic (ROC) curves indicated that values of areas under the curve of the admission day and the 3rd day BNP levels for 28-days mortality were 0.735 (95% CI,0. 621～0. 848, P <0.001) andO.836 (95% CI, 0.746～0,926,P<0.001), respectively. Conclusions Plasma BNP inereaseds in majority of eldedy patients with severe sepsis or septic shock, which may serve as irdex for prognosis in elderly severe septic paients.

0.05).Conclusions Fluid therapy guided by functional hemodynamic index SVV in elderly patients with severe sepsis under MV is safe and more effective than that guided by CVP.SVV is valuable in prodicting the response to fluid treatment in elderly patients with severe sepsis.

Objective To investigate the influence of left ventricular-arterial coupling(VAC) on clinical prognosis of elderly patients with septic shock.Methods A total of 56 elderly septic shoek patients were enrolled in this study,all of whom were admitted to Department of Intensive Care Unit in Zhejiang Hospital from August 2014 to October 2015.The patients were divided into two groups according to the status of left ventricular-arterial coupling when septic shock was diagnosed,which were left ventricular-arterial uncoupling group(UC group) and left ventricular-arterial coupling group(C group).Various parameters were recorded,including blood lactate level,central venous oxygen saturation(ScvO2),serum level of N-terminal pro-brain natriuretic peptide(NT-proBNP) and cardiac troponin Ⅰ (cTN Ⅰ),dose of vasoactive drugs,the total fluid volume and urine volume per hour within 24 hours.The 28-day survival rate was a key index of prognosis.Multivariate logistic regression was taken to analyze risk factors related to death within 28 day.Results Compared with C group,UC group had lower values of left ventricular ejection fraction[(42.43 ±4.76)％ vs (53.17±3.01)％;P＜0.01] and cardiac index[(2.36±0.68) L· min-1 · m 2vs (2.93±0.45)L · min-1 · m-2;P ＜0.01].Yet serum levels of NT-proBNP[lg NT-proBNP 3.93 ±0.53 vs 3.40 ±0.63;P =0.004] and cTN Ⅰ [lg cTN Ⅰ-0.16 ± 0.68 vs-1.03 ± 0.69;P ＜ 0.001] in UC group were higher than those in C group.Moreover,the total fluid volume within 24 hours [(3 806.3 ± 831.4) ml vs (3 142.0±770.0) ml;P =0.016],blood lactate level[(5.61 ±2.68) mmol/L vs (3.93 ± 1.59)mmol/L;P =0.043] and dose of norepinephrine[(0.630 ±0.300) μg · kg-1 · min-1 vs (0.292 ±0.234)μg · kg-1 · min-1;P =0.001] in UC group were greater than those in C group,while ScvO2 [(60.75 ±2.91)％ vs (64.42 ±2.19)％;P＜0.001] and urine volume per hour[(0.518 ±0.358) ml vs (0.926 ±0.678) ml;P =0.007] were less than those in C group.Compared with C group,UC group had a lower 28-day survival rate [43.2％ (19/44) vs 9/12;P =0.049].Ea/Ees ratio was negatively correlated with LVEF,ScvO2 (r =-0.686,P ＜ 0.001;r =-0.411,P =0.002),positively correlated with NT-proBNP,cTN Ⅰ (r =0.294,P =0.028;r =0.363,P =0.006),yet no obvious correlation was noticed with blood lactate level (r =0.170,P =0.21).Multiple logistic regression analysis showed that VAC(OR =11.187,95％ CI 2.489-50.285;P =0.002),lactate level (OR =1.727,95 ％ CI 1.164-2.563;P =0.007) and lg cTN Ⅰ (OR =0.247,95 ％ CI 0.079-0.779;P =0.017) were independent risk factors affecting 28-day mortality.Conclutions In elderly patients with septic shock,left ventricular-arterial uncoupling indicates a lower 28-day survival rate,worse cardiac function and tissue perfusion.Ea/Ees ratio might sever as a predictive indicator of 28-day mortality.

Objective To investigate the role of damaged mitochondria in cardiac cell apoptosis in septic rats and the possible mechanism involved.Methods Seventy-two Sprague-Dawley rats were randomly (random number) divided into negative control group (n =18) and septic group (further divided into three groups as per rats sacrificed 6 h,12 h,and 24 h after endotoxin injection intra-peritoneally,n =18).The hearts of rats were taken.The changes of cardiac morphology were observed under light microscope and scanning electron microscope.Cell apoptosis in situ were examined by using terminal transferase-mediated dUTP nick end-labeling assay and nuclear factor-kappa B (NF-κB) activation in myocardium was detected by using Western blotting to estimate myocardial cell apoptosis.Mitochondrial lipid and protein oxidation were measured to assess oxidative stress,and mitochondrial superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities were determined to estimate antioxidant defense.Results Septic induced inflammatory cells infiltration,myocardium degeneration and effusion in a time-dependent manner.A remarkable expansion of capillaries could be observed in the hearts of infected rats at post-challenge of 24 h.Compared with sham-treated rats,the percentage of apoptosis increased in a time-dependent manner in the hearts of infected rats at 6 h,12 h,24 h of post-injection (P ＜0.05).The concentration of NF-κB p65 in the cytosol decreased gradually and increased in the nucleus during sepsis in a time-dependent manner (P ＜0.05),indicating that septic challenge provoked progressive activation of NF-κB.Mitochondrial cristae disappeared in 6 h of challenge,and significant mitochondrial cristae disappearance,vacuolization,and rupture of mitochondria membrane became markedly obvious 12 and 24 h later.Both SOD and GPx activities decreased,while mitochondrial lipid and protein oxidation increased in a time-dependent manner after 6-24 h of challenge (P ＜ 0.05).Conclusions Septic challenge induced myocardial apoptosis and mitochondrial damage.Further,damaged mitochondria might play an important role by means of alteration of defenses against reactive oxygen species in myocardial cell apoptosis during sepsis.

Objective To investigate the clinical values of central venous pressure (CVP) versus stroke volume variation (SVV) in patients with severe sepsis after early goal-directed therapy (EGDT).Methods Totally 30 mechanically ventilated patients with severe sepsis who underwent goal-achieved EGDT were enrolled and randomly divided into CVP group (study group) and SVV group (control group) according to the data detected by pulse contour continuous cardiac output (PiCCO) analysis device.The differences in 28-day survival,3-day APACHE Ⅱ score,time of ICU stay,duration of mechanical ventilation,number that need CRRT,entral venous pressure (CVP),heart end-diastolic volume index (GEDVI),intrathoracic blood volume index (ITBVI),extravascular lung water index (EVLWI),cardiac index (CI),central venous oxygen saturation (ScvO2),lactate clearance rate and APACHE Ⅱ score were compared between the 2 groups.Results The death rate had no difference between the 2 groups(x2=0.240,P=0.624).Among survival patients in the CVP group,the time of ICU stay and duration of mechanical ventilation were shorter in study group than in control group(t=2.166,P=0.041;t=2.104,P=0.046),APACHE Ⅱ score at 3th day was decreased(t=2.20,P =0.038).The values of ITBVI,GEDVI,CI,lactate clearance rate were higher in study group than in control group (t=2.759,2.146,2.199,2.654,3.362,P=0.011,0.043,0.038,0.014,0.003).EVLWI and APACHE Ⅱ score were not different (P＞0.05) between the two groups.Conclusions SVV as a recovery target for fluid resuscitation can reach a better recovery results and improvement of prognosis than CVP goal-achieved EGDT.

Na +-K +-2Cl-cotransporter 1 (NKCC1) is highly expressed in malignant gliomas,which is closely related to the degree of malignancy.NKCC1 protein has a vital function in the volume regulation of glioma cells.NKCC1 allows glioma cells to transform its volume freely,migrating through the narrow extracellular space to achieve distant metastases.There is also close relationship between NKCC1 and tumor cytoskeleton regulation.In addition,NKCC1 is closely associated with cell cycle,nerve activity and other biological functions.In conclusion,NKCC1 plays an important role in gliomas.
