Objective To explore the effective method of treating childhood acute aplastic anemia(AAA) by overviewing the curative effect of therapeutic alliance to the children diagnosed as AAA with immunodepressants.Methods Retrospective analysis was performed on 13 patients diagnosed as AAA,who were treated by high dose of methyllprednisolone,antilymphocyte globulin,ciclosporin A,large dose of gamma globulin,granulocyte colony-stimulating factor and blood transfusion in 4 years.Results Among 13 cases,9 cases were healing well on the whole,one was relieved,one was improving,two were ineffective(one of them was dead).In 9 cases who were healing,WBC took(24.60?8.86) days to reach 4?10~9/L,hematoglobin took(152.22?68.88) days to reach normal and platelet took(125.55?55.86) days to reach 80?10~9/L.During the procedure of treating,infection appeared in 7 cases,the ALT and AST was high in 2 cases,hypoproteinemia and edema in 1 case,gross hematuria in 2 cases,gingival hyperplasia obviously and dedentition in 1 case.Conclusion Therapeutic alliance with immunodepressants to childhood AAA is a safe and effective method.

In chronic kidney disease (CKD), inflammatory responses during the progression of renal tissue and tissue injury related causes its progression to end-state renal disease. Among them, nuclear factor (nuclear factor, NF)-kappaB signaling pathway by regulating the corresponding nuclear expression of target gene transcription, as well as affecting the synthesis of inflammatory mediators, induction of inflammation lead to kidney damage and renal fibrosis. Some single herbs and their extracts (such as Astragali Radix, Scutellariae Radix, Ginkgo Folium) and some traditional Chinese medicine (such as Danggui Buxue decoction, Qilian decoction) can reduce the inflammatory damage induced by renal tissue NF-kappaB signaling pathway and delay the progression of CKD.

OBJECTIVETo explore the effect of Xinfeng Capsule (XC) on lipoprotein metabolism of rheumatoid arthritis (RA) patients.

METHODSTotally 180 RA patients were assigned to the experimental group and the control group by random digit table, 90 in each group. Patients in the experimental group took XC (three pills each time, three times daily), while those in the control group took Methotrexate Tablet (four tablets each time, once per week). One month consisted of one therapeutic course and all patients were treated for two therapeutic courses. A healthy control group consisting of 60 patients was also set up. Changes of lipoprotein indices, clinical efficacy, lipid metabolism, joint symptoms and signs, activity indicators were observed, and correlation analyses were performed.

RESULTSCompared with the healthy control group, expression levels of prealbumin (PA), globulin (GLO), high-density lipoprotein (HDL), apolipoprotein Al (Apo-A1) were lowered in RA patients (P <0. 05, P <0. 01). Correlation analyses showed that PA was negatively correlated with joint tenderness, morning stiffness time, disease activity score (DAS-28), C-reactive protein (CRP), interleukin (IL)-6, respectively. Total protein (TP) was negatively correlated with joint tenderness. GLO was negatively correlated with joint tenderness and DAS-28. HDL was negatively correlated with erythrocyte sedimentation rate (ESR) and endothelin (ET)-1. Apo-Al was negatively correlated with joint pain; Apo-B was negatively correlated with CRP; LDL was negatively correlated with morning stiffness time (P <0. 05, P <0. 01). Compared with before treatment, expression levels of PA, HDL, Apo-A1 , Apo-B, and serum IL-10 contents increased, and expression levels of ESR, CRP, IL-6, ET-1 , joint pain, joint swelling, morning stiffness time, and DAS-28 decreased in the experimental group (P <0. 05, P <0. 01). PA increased more after treatment than before treatment in the control group (P <0. 01). There was statistical difference in joint symptoms (except joint tenderness) and activity indices (except ET-1) in the control group (P <0. 05, P <0. 01). Compared with the control group after treatment, PA and HDL increased, ET-1 and duration of morning stiffness decreased in the experimental group (all P <0. 05).

CONCLUSIONSLipoprotein metabolic disorder exists in RA patients, and it is associated with disease activity. XC could obviously improve lipoprotein metabolism and joint symptoms.

Objective To summarize the clinical features,diagnosis and treatment of autologous urologic neoplasms in renal transplant recipients.Methods A retrospective analysis on the clinical data of 25 renal transplant recipients was done in our center.The onset time of new neoplasms was between 29 to 72 months after transplantation,with an average of 48.2 months.Intermittent hematuria was the first symptom in 23 patients,and the rest two cases were diagnosed through routine examination. The pathological diagnoses of thee cases were renal carcinoma,which were treated by transperitoneal laparoscopic radical nephrectomy.Eight cases were diagnosed as having renal pelvic tumor,which was treated by radical resection for the renal pelvic carcinoma.Fourteen cases were diagnosed as having bladder cancer,which was treated by transurethral resection of bladder tumor (13 cases) or radical cystectomy (one case).All patients were subjected to surgical treatment.The dosage of MMF,CSA/Tacrolimus was decreased to 1/2-2/3 of their original dosage. Sirolimus was used in place of calcineurin inhibitors in four patients.Immunosuppressive regimes and adjuvant therapy were given after surgery treatment.Results Twenty-five patients were followed up for 12-84 months.Contralateral renal carcinoma combined with lung and chest multiple metastases occurred in one case after radical nephrectomy,who died after targeted therapy 6 months later.Two patients with lymph node metastasis died 14 months and 20 months after surgery respectively.The rest 22 patients were closely followed up,whose creatinine remained 98-163μmol/L.Conclusion More attention should be paid to patients with hematuria after renal transplantation to screen the autologous urinary neoplasms.Patients should be treated with surgical procedures,and immunosuppressive regimens should be adjusted postoperatively.

Objective To establish a method for the rapid detection of hepatitis E virus (HEV)from serum samples based on fluorescence quantitative PCR.Methods (1 )One-hundred HEV sequences including our country popular three major genotypes were obtained from the GeneBank with the Vector NTI software.The proper sequence was selected to design and synthesize the primers of the fluorescence quantitation and the Taqman probe.(2)The amplification region PCR fragment was transcribed in vitro to synthesize cRNA standard,at the same time the trace serum virus lysate was introduced into a universal real-time TaqMan PCR assay.(3)10 clinical serum samples were collected from the patients with clinical hepatitis E and detected by using the established method for further verifying this method.Results This detection technique could effectively detect the serum samples in the pa-tients with genotype I and genotype IV hepatitis E positive,while the serum detection in the patients with other virus infectious dis-eases had the negative results,which verified that this RT-PCR detection technique had higher specificity and good reliability.The detection results from 10 clinical serum samples further verified that this method was rapid,convenient and sensitive with good re-peatability.Conclusion A fluorescence quantitative RT-PCR detection technique suitable for detecting main genotypes of HEV in China population is established,which can meet the demand of early and rapid diagnosis for HEV.

Objective To explore the relationship between physical activity(PA) and the risk of colon cancer. Methods Cohort studies on physical activity and risk of colon cancer were identified by searching MEDLINE, EMBASE, Chinese Bio-medicine and Chinese Wanfang databases from January 1979 to December 2009. Results from the individual studies were synthetically combined in our study. Inverse variance weighting was used in fixed effects model and the random effects estimate was based on the DerSimonian-Laird method. Variance-weighted least squares method was used for trend test of summarized dose-response data. Results A total of 28 studies were included in our analysis. An inverse association between physical activities and the risk of colon cancer was observed with the relative risks (RR) as 0.75 [95% confidence interval (CI): 0.66-0.86] in males and 0.85(95%CI: 0.76-0.95)in females, respectively. However, the findings from those documents with high quality showed significant and borderline significant associations between PA and colon cancer in both males (RR=0.74, 95% CI: 0.61-0.90) and females (RR=0.99, 95% CI: 0.95-1.02). Meanwhile, the dose-response trend was not observed either in males (P=0.142) or in females (P=0.417). For men, the pooled RRs differed by subsites were 0.62(95%CI:0.45-0.85) and 0.74 (95%CI:0.56-0.99)for highest level PA, compared with lowest level PA in proximal colon and distal colon cancer,respectively. For women, the pooled RRs were 0.84 (95%CI: 0.69-1.01 ) in proximal colon and 0.75(95%CI: 0.53-1.05)in distal colon cancer, respectively. Conclusion These results added to the evidence for the protective effects in colon cancer among men and women.

OBJECTIVETo observe the change of PTEN/PI3K/AKT pathway hypoxia-inducible factor (HIF-1α), vascular endothelial growth factor (VEGF) in rats with adjuvant arthritis and to explore the mechanism of neovasculization in rheumatoid arthritis.

METHODSThirty rats were randomly divided into normal control group and model control group. The model control group were established the model of adjuvant arthritis using Freund's complete adjuvant. At 19 days after modeling, the expression of microvascular density (MVD), HIF-1α, VEGF were detected by ELISA assay and PTEN, PI3K, AKT were detected by Werstern Blotting.
