This study investigated the expression and prognostic value of SHP-2 in cervical cancer caused by human papillomavirus (HPV) infection. Forty-five specimens from patients with cervical cancer (stage I-III), 32 specimens from patients with cervical intraepithelial neoplasia (CIN) (I, II) and 20 normal cervical samples from patients with hysteromyoma were collected in Department of Pathology for comparison. The expression levels of SHP-2 and IFN-β proteins were detected by using immunohistochemistry. The mRNA expression level of SHP-2 was detected by using quantitative real-time polymerase chain reaction (PCR). HPVs were detected by HPV GenoArray Test. The Spearman correlation was used to compare the expression level of SHP-2 in HPV infected cervical cancer vs non-HPV infected normal cervix. The level of SHP-2 protein expression in the cancer tissues (88.8%) was significantly higher than in CIN tissues (62.5%) and normal cervixes (45%) (P<0.05 and P<0.05, respectively). The SHP-2 mRNA levels in the cancer tissues were upregulated as compared with those in the normal cervixes (P<0.05). Twenty-one (46.7%) cervical cancers, 25 (78.1%) CINs and 17 (85%) normal cervixes showed IFN-β positive staining in cytoplasm. There was statistically significant difference in the expression rate of IFN-β between cervical cancer and normal cervix (χ (2)=8.378, P<0.05) as well as between cervical cancer and CIN (χ (2)=7.695, P<0.05). HPV16/18 infections could be found in normal cervixs (15%), CINs (68.7%) and cervical cancers (84.4%). There was a correlation between HPV infection and SHP-2 expression in cervical cancer (r (s)=0.653, P<0.05). SHP-2 may be a useful prognostic and diagnostic indicator for HPV infected cervical cancer. In cervical cancers, SHP-2 mRNA and protein overexpression was associated with IFN-β lower-expression.

Objective To investigate the coping style and influencing factors of the recipients after relative kidney transplantation. Methods Medical coping modes questionnaire (MCMQ) and observa-tion interview were performed in the sampling survey, 56 case of recipients after relative kidney transplanta-tion according to the adopted standard were analyzed. Results The confronting score of all the cases were close to that of normal model, but the avoiding score and yielding score significantly increased. The prospective health conditions of the relative donors, function and survival time of the graft kidney, rejection reaction and other complication after transplantation were the main factors affecting the coping style of the recipients. Conclusions Based on the accurate evaluation of the coping style, nursing intervention should be aimed at the recipients following relative riving donor kidney transplantation, in order to help the recipients create a correct coping style and improve the survival rate of patient/kidney.

Objective To evaluate the effect of stage health education on living-relative donor kidney transplantationrecipients.Methods Forty-eightliving-relativedonorkidneytransplantation recipients were randomly assigned to receive stage ( study group,n =24 ) or conventional health education (control group,n =24 ).ResultsIn comparison with the control group,the study group showed better awareness of kidney transplantation and improved satisfaction with nursing ( x2 =8.83,x2 =10.32,P ＜0.05).Conclusions Stage health education improves the awareness of renal transplantation and promotes mental and physical recovery,thus resulting in better quality of life of living-relative donor kidney transplantation recipients.

Objeictivie To investigate the diagnostic value of anti-mutated citrullinated vimentin (anti-MCV) antibody, anti-cyclic citrullinated peptide (anti-CCP) antibodies and glucose-6-phospha-teisomerase (GP1) for rheumatoid arthritis (RA). Methods Anti-MCV antibody, GPI and anti-CCP antibody were detected in serum samples of 109 RA patients, 24 non-RA rheumatic diseases patients and 19 healthy blood donors. The sensitivity and specificity of these parameters for the diagnosis of RA were analyzed. Results Both the positive rate and average cut off concentration of anti-MCV and GPI in RA were higher than those of non-RA rheumatic diseases or healthy controls (P<0.05). A significant difference was found between anti-MCV and GPI in RA patients. The most sensitive and specific parameter in RA was anti-MCV (99.1%) and anti-CCP (90.7%) respectively, but, when anti-MCV combined with anti-CCP, or GPI or anti-CCP and GPI, the specificity could be up to 98.1%. Coniclusions Anti-MCV, anti-CCP and GPI alone or in combination may be valuable parameters for the diagnosis of RA.

To observe the expression of cyclooxygenase (COX)-1 and COX-2 in brain after spared nerve injury (SNI) and compare the analgesic effects of COX inhibitors with different selectivity. Radioimmunoassay, RT-PCR and Western blotting techniques were used to evaluate the change of brain COX expression at different time points( before SNI, 1 h, 12 h, 1 d, 3 d, 7 d, 14 d, 30 d and 60 d after SNI); By exploring hot plate test, we observed the reacting time of animals after injection of saline, NS-398, SC-560 and indomethacin at different time points. The results showed that: ( 1 ) The expression of brain COX-1 didn't increase significantly until 14 d after SNI, while that of COX-2 increased significantly and rapidly after SNI and reached peak at the time point of 1 d ( all P ＜0.05 ); (2) NS-398 showed significant analgesic effect on neuropathic pain after SNI at the early phase ( P ＜ 0.05 ), but didn't persist for over 30 d; ( 3 ) Indomethacin and SC-560 didn't show significant analgesic effects until 14 d. These results suggest that brain COX-1 is involved in the late phase of neuropathic pain and may play a role in the persistence of pain, while brain COX-2 is involved in the early phase of neuropathic pain and may play a role in the pain origination.

ObjectiveTo investigate the effects and problems of problem-based learning ( PBL ) teaching methods that are adopted in the laboratory medicine practice teaching. MethodsOne hundred and four undergraduate students of 5-year system of laboratory medicine were selected to use the PBL teaching methods during the laboratory medicine practice.

AIM: To explore the effects of cellular signal transduction pathways of heme oxygenase-1(HO-1)-carbon monoxide (CO)-cyclic GMP (cGMP) and nitric oxide synthase (NOS)-nitric oxide (NO)-cGMP on cholecystokinin octapeptide (CCK-8) reversed vascular hyporeactivity in endotoxemic rats. METHODS: According to the treatments given in vivo , rats were devided into four groups: control; lipopolysaccharide (LPS); CCK and CCK+LPS. Using isolated vascular ring tension detecting technique, thoracic aortic rings (TARs) were prepared and accumulation of contractive responses to phenylephrine (PE) were measured under which the TARs were incubated with Hemin (He, donor of CO), Zinc-protoporphyrin-IX (ZnPP-IX, selective inhibitor of HO-1), L-arginine (L-Arg, substrate of NOS), aminoguanidine (AG, selective inhibitor of iNOS), N ?-nitro-L-arginine (L-NNA, inhibitor of NOS) or methylene blue (MB, inhibitor of guanylyl cyclase), respectively. RESULTS: CCK-8 alone did not affect vascular tension. Injection of LPS induced the hyporeactivity of the TARs and was reversed by pretreatment of CCK-8. In LPS and CCK+LPS groups, the hyporeactivity was partly reversed by incubation of TARs with ZnPP-IX or AG, and restored to normal by incubation of TARs with L-NNA or MB. Incubation of TARs with He or L-Arg showed to make the vascular hyporeactivity worse in different degree. CONCLUSIONS: CCK-8 alone did not affect the activity of HO-1 and iNOS but influenced the activity of these enzymes induced by LPS, which lead to reduced CO/NO production, decreased the content of cGMP and plays its important role in reversing vascular hyporeactivity in endotoxemic rats.

AIM: To verify the effect of cholecystokinin octapeptide(CCK-8) on cardiac function in endotoxin shock (ES) rats.METHODS: The rats were divided into four groups:control,lipopolysaccharide(LPS),CCK-8 and CCK-8+LPS.The left ventricle pressure(LVP),the maximal/minimum rate of LVP(?LVd p /d t max ),heart rate (HR) and mean arterial pressure (MAP) were measured.The activity of superoxide dismutase (SOD),the contents of malondialdehyde (MDA) and nitric oxide (NO) in both serum and myocardium were also measured,respectively.RESULTS: CCK-8 (40 ?g?kg -1 , iv) elicited bradycardia in short time and gently increase MAP,LVP and ?LV d p /d t max . Lipopolysaccharide(LPS, 8 mg?kg -1 , iv) caused a variation in heart rate (HR)(a bradycardia following a tachycardia) and rapid decreases in MAP,LVP and ?LVd p /d t max . The rapid variation of HR and the decline of MAP,LVP and ?LVd p /d t max were reversed by pretreatment with CCK-8 in ES rats, but didn't restore to normal.The activity of SOD was increased and the contents of MDA and NO were decreased by pretreatment with CCK-8 in ES rats.CONCLUSION: The decline of cardiac function in ES rats could be reversed by pre-administration of CCK-8 and the decrease in NO production may be one of the mechanisms.
