Objective: Serum pleiotrophin(PTN) is closely related to tumor,particularly to lung cancer.Many studies focused on PTN recently.This study is to evaluate the diagnostic value of PTN,Cyfra21-l and CEA tests independently or in a combined style in lung cancer.Methods: Sixty-one patients with lung cancer and 17 patients with benign lung lesion disease all received PTN,Cyfra21-l and CEA tests before the treatment.They were compared with pathological results,and then we calculated the diagnostic value of each method and the combined styles.Results: The sensitivity of PTN together with Cyfra21-l and CEA tests is 95.08% and it is the highest among the methods.Conclusion: PTN together with Cyfra21-l and CEA tests has a important diagnostic value through mutual complementation in detecting lung cancer.

OBJECTIVE:To study the effect and its possible mechanism of Xuezhiping capsule on blood lipid levels of high blood lipid model golden hamsters. METHODS:Golden hamsters were randomly divided into normal control group,model group, atorvastatin group (3 mg/kg),combination group (Xuezhiping capsule 1.3 g/kg+atorvastatin 1.5 mg/kg),Xuezhiping capsule low-dose,medium-dose,high-dose groups(Xuezhiping capsule 1.3,2.6,5.2 g/kg),10 in each group. Hamsters in normal control group received normal diet,the other groups were given high-fat diet to establish high blood lipid model. Then relevant drugs were intragastrically given 2 weeks later. Normal control group and model group were intragastrically given equal volume of distilled wa-ter,once a day,for 4 weeks. After last administration,blood lipid indexes(TG,TC,HDL-C,LDL-C,FFA),mRNA and protein expressions of lipid metabolism related genes (PPAR-α,CYP7A1,ACOX,SREBP-1c,ACC1) were detected. RESULTS:Com-pared with normal control group,serum contents of TC,TG,LDL-C,FFA in model group increased,HDL-C content decreased;PPAR-α,CYP7A1,ACOX mRNA and protein expressions were weakened,SREBP-1c,ACC1 mRNA and protein expressions were enhanced(P<0.05). Compared with model group,above-mentioned indexes were obviously improved in Xuezhiping capsule high-dose group,atorvastatin group and combination group (except for HDL-C in Xuezhiping capsule high-dose group)(P<0.05);TC,TG,FFA contents,and PPAR-α,CYP7A1,ACOX,ACC1 mRNA,and CYP7A1,SREBP-1c,ACC1 protein were obviously improved in Xuezhiping capsule medium-dose group(P<0.05);TC,TG contents,and PPAR-α mRNA,and CYP7A1, SREBP-1c protein were obviously improved in Xuezhiping capsule low-dose group (P<0.05). CONCLUSIONS:Xuezhiping cap-sule has a promising effect of lowering blood lipid,the mechanism may be related to activating PPAR-α and inhibiting SREBP-lc signaling pathway.

Objective To investigate the effect of the extracts of Centella asiatica(L.) Urban (ECA) on the depressive-like behavior alteration in rats and mice. Method 60 Wistar rats were randomly divided into 6 groups (10 rats each), the normal group, model group, Fluoxetine group, ECA high dose group (component 10.08 mg+component 24.48 mg/kg), ECA middle dose group (component 1 0.04 mg+component 2 2.24 mg/kg) and ECA low dose group component 1 0.02 mg+component 2 1.12 mg/kg. Chronic unpredictable mild stress (CUMS) induced depression in rats and sugar consumption to detect the antidepressant effect of ECU. 60 Kunming mice were randomly divided into six groups as above. Locomotor activity, forced swim, tail suspension test were used to detect the effect of ECA on the behavioral alteration in mice. Results Compared with model group, sugar consumption in ECA groups was significant increased (P<0.01). ECA treatments also decreased duration of immobility in the tail suspension test and forced swim. Conclusion ECA could improve the depressive-like behavior in rats and mice.

Objective To discus the diagnosis,favorabl management and diagnosis of pilocytastrocytoma.Methods Provided by the information from CT,MRI and operation,we try to discus and confirm the characteristics of this tumor.Results Pilocytastrocytoma commonly occurs in 20 years old or younger.The most frequent location involve by tumor were cerebellum.The most common presenting sympton was increased intracranial pressure,and then cerebellum symptoms such as incoordination.Final diagnosis made depending on mainly pathology.We found the relationship between prognosis and the extent of surgical removal.Conclusions Pilocytastrocytoma usually occur in children and adolescent.The most common site of these tumors are the cerebellum.And the more complete extent of surgical removal,the better prognosis.So it was called as "benign" tumors.If pilocyticastrocytoma were subtotally excised,the addition of postoperative irradiati could significantly prolong survival.

Objective To investigate the effect of minocycline on the cognition and expressions of brain-derived neurotrophic factor (BDNF), apoptosis related factor Bcl-2 and Bax in hippocampus of rats with Alzheimer’s disease (AD).
Methods The rat model was established by microinjection of Aβ25-35 into lateral ventricle. Thirty healthy male SD rats were randomly divided into three groups:control group, model group and minocycline treatment group. Normal saline 1 mL/(kg·d) was intraperitoneally injected in control group and model group. The minocycline treatment group was intraperitoneally injected with minocycline 50 mg/(kg · d) for 14 days. Morris water maze was used to detect the behaviors of animals. The expressions of BDNF, Bcl-2 and Bax in hippocampus were measured by Western blotting and enzyme linked immunosorbent assay (ELISA). The apoptosis of neurons was detected by TdT-mediated dUTP nick-end labeling (TUNEL). Results Minocycline greatly improved the behaviors of AD rats, up-regulated the expressions of BDNF and Bcl-2, and down-regulated the expression of Bax in hippocampus, and reduced cell apoptosis. Conclusion Minocycline plays a protective role in neural function by promoting the growth of neurons and inhibiting the neuronal apoptosis.

Objective To study the etiology, clinical and pathological characteristics, therapy and prognosis of acute renal failure (ARF). Methods The literature of 80 treated children with ARF from 1988. 1 to 2003.10 was reviewed. Results Sixty three cases (78.8%)suffered from mtrarenal ARF;47 glomerulonephritls (58. 8%); 15(18. 8%)prerenal ARF;2(2 5%)postrenal obstructive ARF. Twenty three cases with renal biopsy,9(39. 1%)MsPGN;4 (17. 4% ) MPGN; 4 (17. 4%) crescentic glomerulonephntis; 3 (13% ) endocapillary glomerulonephritls;2(8 7% )proliferative and sclerosing glomerulonephritis; 1(1. 3% )minimal changes. According to the different etiologic and pathological characteristics,different therapies were applied,infusion,oral prednisone ,and intravenous pulses of methylprednisone and cyclosphosphamide ,dialysis, or diuretic therapy and lowering blood. Thirty one (38. 8% )cases recov-ered;27(33 8% )cases improved; 10( 12.5% ) cases gave up treatments;21 (26 3% )died. The mortality of ARF from 1996 to 2003 was significantly lower than that from 1988 to 1995(x2 = 7.85 P

ObjectiveTo evaluate the significance of CK19 mRNA monitoring in peripheral blood of breast cancer patients.MethodsPeripheral blood samples were collected from 137 breast cancer patients preoperatively,one day post-operation,7 days,1,3,6,12,18,and 24 months after operation.RTPCR was used to detect CK19 mRNA expression.The relationships were analyzed between CK19 mRNA expression and treatment result, between CK19 mRNA expression and clinicopathological parameters.ResultsThere was no significant difference between the level of CK19 mRNA as tested preoperatively,and 1,7 days postoperatively(P ＞ 0.05 ).From one month and thereafter,CK 19 mRNA decreased significantly when compared with that immediate perioperatives ( P ＜ 0.05 ). Postoperative peripheral CK19 mRNA expression increased in those found with recurrent or metastasized tumors ( P ＜ 0.01 ). CK19 mRNA expression does not correlate with patient's menstrual status,estrogen receptor expression,progesterone receptor expression,HER-2 expression and Ki67 proliferation expression (P ＞ 0.05 ). But there was statistically significant correlation between CK19 mRNA expression and tumour size,histology grading,pathological type,lymph node metastasis ( P ＜ 0.01 ).ConclusionsIn breast cancer patients peripheral blood CK19 mRNA expression is correlated with risk clinicopathological parameters, and increases in patients with postoperative recurrence and tumor metastasis.

ObjectiveTo study the role of laparoscopic splenectomy (LS) using the anterior approach with sequential layered dissection. MethodsFrom December 2007 to July 2009, we performed 27 LS using the anterior approach with sequential layered dissection. The clinical data were retrospectively analyzed. ResultsThe range of splenic length was 8-20 cm. Accessory spleen was found in 6 patients (22.2%). The mean operative time was 125 mins. The mean intraoperative blood loss was 90 ml, and the mean postoperative stay was 5.5 days. ConclusionsLaparoscopic splenectomy using the anterior approach with sequential layered dissection could be carried out smoothly and rapidly. It reduced accidental injuries and shortened the operative time.

Objective To investigate the effect of special CT monochromatic images on improving imaging quality in Budd-Chiari Syndrome.Methods 40 patients with Budd-Chiari Syndrome underwent CT venography (CTV)with gemstone spectral imaging (GSI).Using the optimal contrast to noise ratio (CNR)curve of GSI software,the optimal CNR monochromatic images of the infe-rior vena cava and hepatic vein were chosen.The CT value of the intrahepatic segment of inferior vena cava,hepatic vein and the same level liver tissue were measured,and the CT value of the same region were measured on 140 kVp mixed energy images and 70 keV images.CNR on the optimal monochromatic images,the 140 kVp mixed energy images and 70 keV images were calculated respectively,and the image quality of the optimal monochromatic image,the 140 kVp mixed energy images and 70 keV images were subjective scoring.One-way ANOVA was used for statistical analysis using SPSS1 7.0 software.Results The optimal keVs from monochromatic images were distributed at 40 keV (50%)and (5 1 ± 1 )keV (50%)for IVC and 40keV (25%)and (53 ± 3)keV (75%)for HV.The CNR and CT value and subjective score of IVC/HV got from the optimal monochromatic images were signifi-cantly higher than those from 140 kVp mixed energy images and 70 keV images respectively(P <0.01 ).Conclusion The optimal monochromatic images provide higher image quality of IVC and HV in patientswithBudd-Chiari syndrome.

Objective To explore the clinical effect of transvaginal repair of cesarean scar diverticulum (CSD). Methods Totally 64 patients of CSD in the First Maternity and Infant Hospital, Tongji University between Mar. 2013 and Sept. 2014 underwent transvaginal repair of CSD were reviewed retrospectively and followed. Result All the patients had a prolonged period, and the duration was (14.8± 3.5) days; all the patients were received the transvaginal repair of CSD, there was no intra-operative complications, the procedures were successfully performed in all patients. The mean operation time was (67± 12) minutes, the mean blood loss was (53±32) ml, and the mean length of hospital stay was (4.0±1.1) days. All patients were followed after the operation, the duration of menstruation was (8.1 ± 3.5) days shorter in average, which was statistically significant (P<0.01);the operation effective rate was 94%(60/64) to assess the clinic syptoms, the operation effective rate was 95%(61/64) for anatomic assessment. The distance of the CSD from the serosa became thicker after surgery significantly, the distance was thicker (3.4 ± 0.4) mm compared with preoperation (P<0.01). Conclusions Transvaginal repair of CSD offers minimal invasiveness, good exposure and accurate resection. It is worth to be popularized in the treatment of patients with CSD.
