Objective To appraise the value of combined multiple tumor markers in the diagnosis of ovarian tumors. Methods Eighty-three patients with ovarian tumors confirmed by pathological diagnosis were tested with combined multiple tumor markers including CA125,CA19-9,alpha-fetoprotein (AFP),carcinoembryonic antigen (CEA), serum ferritin (FT) preoperatively by automated chemiluminescence assay,and the relations between the results and the pathological diagnosis were analyzed retrospectively.Results There was statistical difference among the positive rates of tumor markers in malignant [ 83.87%(26/31 ) ] and benign ovarian tumors [ 36.54% (19/52) ] (P ＜ 0.05 ). Every tumor marker had its sensitivity and specificity,but CA125 was the best marker of all. Its sensitivity was 74.2%, specificity was 55.8%,positive predictive value was 50.0% ,the specificity of CEA,AFP and FT was all 98.1%, the sensitivity of those was 16.1%, 3.2%, 16.1% respectively. When combined with the others,it could improve its specificity and positive predictive value,but the sensitivity declined greatly. Conclusion The accuracy of distinguishing the malignant from benign ovarian tumors is enhanced by combined multiple tumor markers testing.

Objective To investigate the prostate cancer diagnosis value of prostate-specific antigen (PSA) and free prostate-specific antigen (FPSA) change quantity before and after antibiotic treatment in patients with abnormal PSA.Methods Eighty-five patients with elevated PSA were selected,and the patients were treated with antibiotic (levofloxacin intravenous drip for 1 week).The PSA and FPSA levels were detected before and after treatment.All of the patients underwent prostate needle puncture biopsy.The relation between the PSA,FPSA change quantity before and after treatment and the puncture biopsy positive rate were analyzed.Results The PSA and FPSA levels after treatment were significantly lower than those before treatment:(5.82 ± 1.61) μ g/L vs.(7.71 ± 1.32) μ g/L and (0.80 ± 0.14) μ g/L vs.(0.98 ± 0.17) μ g/L,there were statistical differences (P ＜ 0.05).In 85 patients,10 cases were puncture biopsy positive.After treatment,no PSA change was in 8 cases,PSA decreased ＜ 10％ was in 27 cases,PSA decreased 10％-30％ in 24 cases,PSA decreased 31％-50％ was in 18 cases,and PSA decreased ＞ 50％ was in 8 eases,and puncture biopsy positive were 1 case (1/8),4 cases (14.8％,4/27),3 cases (12.5％,3/24),2 cases (2/18),0case,respectively.Conclusions The PSA can decrease after antibiotic treatment in patients with abnormal PSA,and small decrease of PSA does not mean that the risk of prostate cancer disappears,but the PSA decrease ＞ 50％ after antibiotic treatment means the risk of prostate cancer decreases,which may be closely observed.In patients unable to tolerate or unwilling to accept the prostate needle puncture biopsy,the PSA change quantity before and after antibiotic treatment can help to diagnose prostate cancer.

OBJECTIVE:To provide reference for rational application of tigecyclinet and alert to the occurrence of severe ADR.METHODS:Fifity patients receiving tigecycline in a level 3 general hospital during 2013-2015 were analyzed retrospectively to observe the change of symptom,sign and lab indexes after using Tigecyclinet injfection.Possible ADR of tigecycline,processing and outcomes were summarized.RESULTS:Among 50 patients,there were 24 cases of ADR,including 10 cases of inducing or aggravating blood coagulation abnormality (41.67％),9 cases of liver function injury (37.50％),4 cases of vomiting and other gastrointestinal discomfort (16.67％),1 case of red erythra with itching (4.17％).ADR of digestive system were mild and recovered after symptomatic treatment as inhibiting acid,antiemetic.Severe ADR as Liver function injury could not be recovered after symptomatic treatment as protecting liver,reducing enzyme.Nine cases of liver function injury mainly manifested as the elevation of TBIL,DBIL,ALP,LDH;8 of which suffered from liver function injury before medication and the symptom was aggravated after medication;liver function injury appeared in 3 cases on 10th day after medication and in 2 cases on 9th day after medication.Ten cases suffered from coagulation function disorder before medication and the symptom was aggravated after medication,which mainly manifested as the prolongation of APTT and TT and the elevation of INR,PT,D-dimer,etc.The coagulation function disorder was aggravated abnormally on 2nd-22th day after using tigecycline,mainly appearing on 2nd-5th day (70.00％).CONCLUSIONS:Great importance should be attached to severe ADR as coagulation function disorder,liver function injury when using tigecycline,in order to ensure the safety of drug use.

OBJECTIVE:To provide reference for rational use of antibiotics in community-acquired pneumonia (CAP) pa-tients. METHODS:Medical records of 342 CAP inpatients in our hospital during Jan.-Dec. in 2014 were analyzed retrospectively by DDDs and SPSS 19.0 statistical software. According to the age,the patients were divided into youth group,the young group, middle age group and elderly group,and clinical information and the use of antibiotics were analyzed statistically. RESULTS:Mi-crobiological examination of 320 of 342 CAP inpatients were performed with detection rate of 93.57%;sputum culture,blood cul-ture and PCT were conducted in 67 case to find out pathogenic bacteria with negative rate of 20.18%. 338 patients had used antibi-otics (98.83%),and other 4 patients refused anti-infective treatment. Selected empirical antibiotics of our hospital were mainlyβ-lactam (50.07%),quinolones (35.70%) and macrolides (9.80%). CAP inpatients were mainly given two-drug therapy,of which cephalosporin combined with quinolone were most common,including 178 cases in total (53.61%). During treatment,17 patients suffered from ADR,with incidence of 5.03%. CONCLUSIONS:The detection rate from patients with CAP in our hospital is high in microbiological examination,but culture results should be analyzed dialectically according to clinical signs. Empirical an-ti-infective therapy mainly include β-lactams,quinolones and macrolides antibiotics alone or in combination with,basically meet the guideline for CAP Diagnosis and Therapy Guideline.

OBJECTIVETo evaluate the role of serum tumor necrosis factor-alpha (TNF-alpha) and adiponectin on insulin resistance in different fat diet rats.

METHODSThirty weanling female rats were randomly divided into 3 group (n = 10): a low-fat soybean oil (LFS; 22% of total energy fed as fat), high-fat soybean oil (HFS; 40% of total energy fed as fat), or high-fat soybean oil and swimming training at the same time (HFS + T). After fed for 10 weeks, the level of TNF-alpha, adiponectin in serum of rats were observed.

RESULTS(1) The body weight, percentage of body fat of HFS group increased compared with that of LFS group (P < 0.05), however those of HFS + T group were decreased (P < 0.05). (2) The level of serum insulin and ISI in HFS group were increased by LFS group (P < 0.05), in HFS+ T group the levels decreased. (3) And the serum level of TNF-alpha and IL-6 in HFS group were higher than those in LFS group (P < 0.05), the serum levels of adiponectin in HFS group were lower than those in LFS rats, and in HFS+ T group the levels of TNF-alpha and IL-6 were lower than those in HFS group (P < 0.05), the adiponectin level was higher than that in HFS group, and there were no significant difference between LFS group and HFS + T group.

CONCLUSIONExercises training could improve sugar and fat metabolism disorders, which also contributes to improving insulin resistance caused by high-fat diet.
