Objective To study the relationship of epidermal growth factor (EGF) and pregnancy induced hypertension (PIH), the role of EGF in PIH and fetal growth restriction (FGR), and the effect of EGF on the fetal development in PIH. Methods Thirty-five severe PIH (SPIH, 17 with FGR and 20 without FGR) and twenty-two normal pregnancies were selected . The concentrations of EGF in plasma were analyzed by RIA. The expressions of the EGF receptor (EGFR) in placenta were assayed by immunohistochemistry. Results (a) The EGF concentration in plasma. EGF concentration (96?46 ng/L) was found significantly lower in SPIH than that (144?36 ng/L) in normal pregnancy. P0.05. (b) The levels of HPL in serum were positively correlated with the concentrations of EGF. (c) The immunostaining of EGFR in placenta. The EGFR immunostaining was more highly impressed in SPIH placent than that in normal (P0.05. Conclusion The level of EGF in plasma in SPIH is lower than that in normal pregnancy. But the expression of EGFR is higher. The long existence of lower EGF level in SPIH might lead to the depressed placental function and the occurrence of FGR.

AIM:To investigate whether minocycline postconditioning protects rat myocardium from ischemia-reperfusion ( I/R ) injury through attenuating poly ( ADP-ribose ) polymerase-1 ( PARP-1 ) excessive activation. METHODS:The left anterior descending coronary artery was ligated for 45 min and then reopened for 2 h to establish the rat model of myocardial ischemia-reperfusion injury.The male Wistar rats ( n =90 ) were randomly divided into sham group, I/R group, low-and high-dose minocycline groups, and 3-aminobenzamide (3-AB, PARP inhibitor) group.The myocardial infarct size was measured by Evans blue and 2,3,5-triphenyltetrazolium chloride ( TTC) staining.The morpho-logical changes of the myocardium were observed with HE staining.The cardiomyocyte apoptosis was detected using in situ TDT-mediated dUTP nick end labeling ( TUNEL) .The level of tumor necrosis factorα( TNF-α) and interleukin 1β( IL-1β) in the serum were measured by ELISA.The content of poly( ADP-ribose) ( PAR) in the reperfused myocardium and peripheral leukocytes were detected by Western blot.RESULTS: Compared with sham group, PAR expression, TNF-αcontent and IL-1βconcentration increased in all other groups.Compared with I/R group, treatment with low and high doses of minocycline and 3-AB significantly reduced the infarct size and myocardial apoptosis.PAR expression, TNF-αcontent and IL-1βconcentration in low-and high-dose minocycline groups and 3-AB group all decreased.No significant difference of the above parameters between high-dose minocycline group and 3-AB group was observed.CONCLUSION: Minocy-cline postconditioning may attenuate myocardial ischemia-reperfusion injury by depressing the activation of PARP-1 in car-diomyocytes and peripheral leukocytes in rats.

Conclusions The self-developed "The Compliance Scale Among Kidney Transplantation Recipients" could be a useful tool for evaluating compliance among kidney transplantation recipients.

Discoidin domain receptor 2 (DDR2), a tyrosine kinase receptor belonging to DDRs family, is associated with progression of various cancers. Studies have indicated that DDR2 expression is upregulated in various cancer tissues, which could promote tumors proliferation, invasion, and metastases. Furthermore, patients with high DDR2 expression showed poor 5-year overall survival rate. In addition, DDR2 point mutation can enhance the sensitivity of tumor cells to small molecule tyrosine kinase inhibitor dasatinib, which suggests that DDR2 mutation may be a promising target for cancer therapy.

Objective To observe the effect of effective monomer of Kangxianling prescription on renal function and extracellular matrix composition of 5/6 nephrectomy rats model, and provide basis for the screening of effective traditional Chinese medicine of anti-renal fibrosis. Methods Sixty SD rats were randomly divided into normal group, model group, chrysophanol group, salvianolate A group, oleanolic acid group and losartan group. The kidney fibrosis model was made by operation. Two months after intervented by correspong drugs, renal pathological changes of all groups were observed, the levels of renal function indexes were detected, and real-time PCR assay was used to detect laminin (LN), fibronectin (FN), type Ⅲ collagen (C-Ⅲ), type Ⅰ collagen (C-Ⅰ) mRNA expression in rat kidney tissue. Results SCr and BUN in model group increased significantly compared with the normal group (P<0.01). SCr and BUN in salvianolate A group decreased significantly compared with the model group (P<0.05, P<0.01). BUN in salvianolate A group decreased significantly compared with the losartan group (P<0.01). The expression of C- ,Ⅲ C-Ⅰand LN were reduced by effective monomer of Kangxianling prescription. Conclusion Effective monomer of Kangqianling prescription can inhibit renal fibrosis through reducing the expression of extracellular matrix components, thereby improve the renal function.

Objective To explore the depression and its related factors of the patients with craniocerebral injury during rehabilitation.Methods 111 patients with craniocerebral injury were investigated with the questionnaire about general condition. They were assessed withHamilton Rating Scale for Depression (HAMD). The relationship between the general condition and the score of HAMD were analyzed. ResultsThere were 27 cases (24.32%) with score of HAMD≤7, 31 cases (27.93%) with the score from 8 to 17 and 53 cases (47.75%) with thescore≥18. The score of HAMD was significantly related to the patients' age, education, profession, economy status, economic compensationand the cause of injury (P<0.05). However, it was not related to the sexuality, marital status, registered residence, level of the injury, thecourse of disease and the coma time (P>0.05). Only economy state (x₁), education (x₂) and economic compensation (x₃) entered into the regressionequation by multiple regression analysis: y=22.782-6.879x₁+2.357x₂+3.54x₃ (F=75.609, P=0.000). Conclusion Patients with craniocerebralinjury generally depress during rehabilitation. The patients with a worse economy state, a higher education and no economic compensationappear more serious depression.

Objective To study the difference and clinical significance of serum Angiopoietin-2 (Ang-2) level in gastric cancer, precancerous disease and the changes in post operation follow-up patients.MethodsSerum Ang-2 and CEA levels were detected with ELISA method in 158 gastric cancer patients, 31 chronic astrophic gastritis patients, 38 gastric adenomatous polyp patients, 28 chronic gastritis patients with benign gastric ulcer and 30 healthy controls.The changes of serum Ang2 levels in 131 patients with radical gastrectomy were measured in 2-year post-operational followed-up and the prognosis was also evaluated.The correlation between serum Ang-2 level and the pathologic character of gastric cancer was analyzed.ResultsThe serum Ang-2 and CEA levels of gastric cancer group were (331.8± 64.3) μg/L and (42.6 ± 37.3) μg/L, respectively, which were significantly higher than those of healthy control group [(187.4±32.7) μg/L and (4.2±3.1) μg/L]and benign gastric ulcer group [(197.3±35.4) μg/L and (4.5±3.2) μg/L](all P ＜0.01).The serum Ang-2 level in chronic astrophic gastritis group was also markedly increased (P＜0.05), however there was no significant change in CEA level.There was no obvious change of Ang-2 and CEA level in gastric adenomatous polyp group (P＞0.05).Pre-operation serum Ang-2 levels of the relapse group and the metastasis group were significantly higher than that of no relapse group (P＜0.05).Post-operation serum Ang-2 level of no relapse group decreased to normal range in 1 month and without obvious increase in 2 years follow-up.The serum Ang-2 level of the relapse group also decreased to normal range in 1 month post-operation, while which was significantly higher than that of no relapse group and normal control group from 6 months to 2 years after operation (P＜0.01).Serum Ang-2 level of the metastasis group was markedly higher than that of no relapse group and normal control group during 2 years after operation (P＜0.01).The 2-year survival rate of no relapse group was significant higher than that of relapse group and metastasis group.The change of serum Ang-2 level was correlated with in the gastric cancer differentiation degree, TNM pathologic classification, lymphatic metastasis, distant metastasis, the depth of invasion and the tumor size (P＜0.01), however not correlated with histopathology type and the location of tumor.ConclusionSerum Ang-2 level may be a new and valuable gastric cancer marker, which will help to monitor tumor relapse, migration and prognosis assessment.

Objective:To investigate the clinical characteristics,treatment and prognosis of primary pe-noscrotal extra-mammary Paget’s disease (PSPD).Methods:The clinical and pathological data of 22 cases of primary PSPD were retrospectively reviewed.Survival rate of the overall patients,the invasive patients,and the patients with positive surgical margin or negative surgical margin were analyzed with Ka-plan-Meier survival curve method.Results:Among all the patients with primary PSPD,the median age of onset was 64.5 (39 -84)years,the median time of disease duration was 40 (2 -300)months,and the median long diameter of lesion was 4.75 (1 -10)cm.In the study,12 patients (54.5%)were in pathological stage A1,6 patients (27.3%)were in pathological stage A2,and 4 patients (18.2%) were in pathological stage B.Scrotum and penile of most patients (n =12,54.5%)were involved,5 patients (22.7%)were scrotum only,and 5 patients (22.7%)were penile only.Erythema (n =18, 81.8%),itchiness (n =16,72.7%),ulcerate (n =12,54.5%),exudation (n =11,50.0%),and pain (n =4,18.2%)were the major manifestations.All the patients with primary PSPD were treated with wide surgical excision.The rate of invasive patients was 77.3% (n =17).Of them,6 patients had positive surgical margin.The surgical margins of non-invasive patients were all negative.Twelve patients exhibited local recurrence or/and metastases,and the status of surgical margins (P =0.015)and the depth of invasion (P =0.010)were important risk factors.Inguinal lymph nodes were generally in-volved.The difference of the delay of diagnosis between metastasis and non-metastasis was significant (P =0.040).The 5-year survival rates of the overall and invasive patients were 33.7% and 27.9%, respectively.The patients with positive surgical margin had poor prognosis.Conclusion:Primary PSPD, with the characteristics of long duration,high invasive tendency and high incidence of local recurrence or metastases,generally occurs in the elderly.Surgery should be performed at first.The delay of diagnosis, positive surgical margins and the involvement of inguinal lymph node are important risk factors.Biopsy, frozen section and inguinal lymph node biopsy (ILNB)can standardize diagnosis and treatment.

Objective:To investigate the methylation status of the RASSF1A gene promoter in upper tract urothelial carcinoma (UTUC)tissues and its correlation with clinicopathologic characteristics and postoperative recurrence of primary UTUC.Methods:In a retrospective design,a total of 687 patients who underwent surgeries for primary UTUC in the urology department of Peking University First Hospital were enrolled.The methylation status of the RASSF1A gene promoter was analyzed using methylation-sen-sitive polymerase chain reaction on tumor specimens.Results:Aberrant methylation for the RASSF1A gene promoter was detected in 183 (26.6%) DNA samples in total.Aberrant methylation of the RASSF1A gene was strongly associated with tobacco consumption (P =0.044),ipsilateral hydronephrosis (P <0.001 ),tumor location (P <0.001 ),tumor stage (P =0.001 ),tumor grade (P =0.007), lymph node metastasis (P =0.001 )and growth pattern (P =0.013).The methylated RASSF1A gene promoter was an independent risk factor for bladder recurrence (P <0.001,HR =0.471)and contrala-teral recurrence (P =0.030,HR =0.269)of UTUC after surgery.Hypermethylated RASSF1A was pre-dictive for improved bladder recurrence-free survival (BRFS)(P <0.001)and contralateral recurrence-free survival (CRFS)(P =0.021)in the UTUC patients.Compared with the patients with unmethylated RASSF1A,the patients containing tumors with hypermethylated RASSF1A had tendency toward longer re-currence-free survival time [(114.4 ±3.9)months vs.(84.0 ±3.2)months for BRFS,(138.1 ±1.8) months vs.(132.9 ±1.9)months for CRFS]and higher estimated cumulative recurrence-free survive rates (five-year survival rate for example,79.8% ±3.4% vs.57.4% ±2.6% for BRFS,98.9% ± 0.8% vs.93.0% ±1.4% for CRFS).Additionally,tumor multifocality (P =0.002,HR =1.538), and ureteroscopy before surgery (P =0.001,HR =1.725)were independent risk factors for bladder re-currence in postoperative UTUC patients.Conclusion:The methylation status of the RASSF1A gene pro-moter appears to be a promising epigenomic biomarker for assessing the aggressiveness of UTUC and a predictor predicting the urinary tract recurrence after surgery.
