Chinese Journal of Postgraduates of Medicine 2010;33(24):18-20
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.

Chinese Journal of Postgraduates of Medicine 2015;38(3):192-194
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.

Chinese Journal of Applied Physiology 2013;29(3):280-282
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.

Objective To explore the effect of chromofungin (CHR), a chromogranin A (CGA) derived peptide CGA47-66, on hyper-permeability of blood brain barrier in septic mice. Methods 120 healthy male C57BL/6 mice were randomly divided into groups, with 12 mice in each group. Seventy-two mice were used for dynamic observation of the contents of water and Evan blue (EB) in brain tissue after being treated with lipopolysaccharide (LPS). Another 48 mice were divided into normal saline control group (NS group), LPS induced sepsis model group (LPS group), low-dose CHR pretreatment group (CL+LPS group), and high-dose CHR pretreatment group (CH+LPS group). The septic model was reproduced by intraperitoneal injection of 10 mg/kg LPS 0.1 mL, and the mice in NS group was given equal volume of normal saline. The mice in CL+LPS group and CH+LPS group were intraperitoneally injected with 15.5 μg/kg and 77.5 μg/kg CHR 10 minutes before LPS injection. Six hours after LPS injection, 4 mL/kg of 2% EB was injected via caudal vein, the contents of water and EB in brain tissue were determined, and EB immune fluorescence in brain tissue was determined to assess the changes in permeability of blood brain barrier. Brain pathology was observed with hematoxylin and eosin (HE) staining. Results With the extension of time after LPS injection, the contents of water and EB in brain tissue were gradually increased, and the time of difference with statistical significance appeared earlier when compared with that of control group in the contents of water than that in EB contents (3 hours and 6 hours, respectively). The contents of water and EB in brain tissue in LPS group were significantly increased as compared with NS group [water content: (79.77±0.62)% vs. (78.28±0.44)%, P < 0.01; EB content (μg/g): 13.87±4.50 vs. 7.13±1.76, P < 0.05]. CHR pretreatment with either of two dosages could reverse the increase in water and EB contents in brain tissue induced by LPS, and the effect was more significant in CH+LPS group [water content: (78.15±0.73)% vs. (79.77±0.62)%, EB (μg/g): 7.09±2.59 vs. 13.87±4.50, both P < 0.05]. It was shown by EB fluorescence observation that the fluorescence signal displayed only in the meninges in NS group, and EB fluorescence was widely distributed in brain parenchyma in LPS group, indicating that the EB leakage in LPS group was more marked than that of NS group. In CHR pretreatment groups, EB fluorescence was decreased in brain parenchyma, indicating that EB leakage was significantly less marked, while it was more obvious in high dose CHR group. It was shown by HE staining that cerebral blood vessel structure was intact in NS group, and the gap around blood vessel was not significant increased. On the other hand, brain structure in LPS group appeared loose, with widening of small perivascular spaces and obvious edema. Brain edema in CHR pretreatment groups was improved as compared with that of the LPS group, and it was more apparent in high dose CHR group. Conclusions LPS induced change in blood brain barrier permeability in mice in a time-dependent manner. Exogenous CGA derived peptides CHR can inhibit LPS induced hyper-permeability of blood brain barrier in septic mice, thus reduces brain edema, protects the brain tissue, and the effect is more obvious with a high dose of CHR (77.5 μg/kg).
