Objective To investigate the diagnostic and therapeutic experience in children with ulcerative colitis(UC) from clinical data.Met-hods The literature on UC in children publicated from 1995 to 2004 were retrieved by CBM,CNKI and VIP database.The clinical manifestations,X-ray,endoscopic and histologic features,management and prognosis of 172 patients in this hospital correspond with the inclusion criteria were retrospectively investigated and a definite diagnosis with UC was made.Results Of 172 patients,the ratio of maleold female was 1.07:1.0,and the age of patients ranged from 2 months to 15 years old.Thirty-six patients(36.7%)were less than 3 years-old;the course ranged from 3 days to 4 years.One patient had family history.The main manifestations were chronic diarrhea,mucus bloody stool,bloody purulent stool and abdominal pain.The systemic symptoms were fever,weight loss,malnutrition and anemia,no enteral symptoms and complications.The lesions were mainly seen in the whole colon with moderate to severe degree.The therapies based on salicylaxosulfapyridine(SASP) or 5-acetylsalicylic acid(5-ASA) together with corticosteroid in the short period have clinical remission in different levels.From long follow-up,the complete remittence was less than one third.Conclusions It is not rare to see UC in infantile.The clinical characteristics of UC in children are different from those in adults,the same is true before and after 3 year-old.The UC in children has high misdiagnosis and is difficult to manage.It is very necessary to establish a diagnostic and therapeutic guideline for children with UC in China.

Objective:To examine the serum proteomic spectra of human esophagial carcinoma by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS),so as to set up a diagnostic model of esophagial carcinoma and to investigate its clinical value. Methods:Thirty-two esophagial carcinoma patients and 28 healthy controls were obtained from Fourth Affiliated Hospital of Hebei Medical University during May to September of 2008. Serum protein was extracted by weak cation exchange (WCX) protein chip system,and proteomic spectra was examined by MALDI-TOF MS. The obtained data were analyzed by ZUCI-protein chip data analyze system (ZUCI-PCDAS) and an esophagial carcinoma diagnostic model was established by genetic arithmetic (GA) combined support vector machine (SVM). The above 60 samples were randomly divided into training set and blinding test set,with training set including 21 esophagial carcinoma patients and 19 healthy controls and blinding test set including 11 esophagial carcinoma patients and 9 healthy controls,so as to examine the specificity and sensitivity of this diagnostic model. Results:Serum proteomic spectra of esophagial carcinoma patients and healthy controls were obtained by MALDI-TOF MS,and m/z (mass to charge) peaks of 44 differential proteins were obtained after analyzed by ZUCI-PCDAS software package (P

The field of gene therapy has been increasingly studied in the last four decades, and its clinical application has become a reality in the last 15 years. Traditional Chinese medicine (TCM), an important component of complementary and alternative medicine, has evolved over thousands of years with its own unique system of theories, diagnostics and therapies. TCM is well-known for its various roles in preventing and treating infectious and chronic diseases, and its usage in other modern clinical practice. However, whether TCM can be applied alongside gene therapy is a topic that has not been systematically examined. Here we provide an overview of TCM theories in relation to gene therapy. We believe that TCM theories are congruent with some principles of gene therapy. TCM-derived drugs may also act as gene therapy vehicles, therapeutic genes, synergistic therapeutic treatments, and as co-administrated drugs to reduce side effects. We also discuss in this review some possible approaches to combine TCM and gene therapy.

Objective To investigate the pharmacokinetics ( PK ) and pharmacodynamics ( PD ) processes of rabeprazole in inhibiting gastric acid secretion with the combined PK-PD model. Methods A total of 10 healthy volunteers were given a intravenous infusion of 20 mg rabeprazole over a 30-min period. The concentration of rabeprazole in the plasma at different time points was detected by HPLC,and the PK parameters were calculated by DAS 2. 0 software. At the same time the intragastric pH was monitored over 24 hours to fit the PD parameters with indirect inhibition model. Results The main PK parameters,t1/2,Cmax,and AUC were(60. 5±17. 3)min,(1 299. 1±201. 0)ng·mL-1,and(106. 4±26. 0)mg·min·L-1, respectively.The corresponding PD parameters,Kin,Ke,IC50 and Imax were(8.200±3.362)h-1,(1.080±0.378)h-1,(0.286± 0. 129)mg·L-1 and(6. 93± 2. 15)pH,respectively. Conclusion The PK of rabeprazole in healthy volunteers conforms to one compartment model,and the PD fits the indirect response inhibition model. The equation can effectively establish the relationship between the blood drug concentration and the effect.

OBJECTIVE To comprehend the bacterial infection and resistance to antimicrobial agents of the pathogenic bacteria causing chronic prostatitis(CP),so as to provide scientific basis for the diagnosis and treatment of CP.METHODS Bacterial culture and antimicrobial agents sensitivity tests were applied to prostatic fluid in 143 patients with chronic prostatitis.RESULTS A total of 85 strains of bacteria were isolated from 143 clinical specimens and the positive rate was 57.34%.In these strains,Gram-positive cocci were the most predominant accounted for 85.9%,coagulase negative Staphylococcus(CNS) were the highest ones and accounted for 60.0% among Gram-positive cocci.S.aureus and Entercoccus were respectively accounted for 12.9% and 11.8%.The ratio of drug resistance of CNS was high for ?-lactamases,quinolones,erythromycin and tetracycline and they were more sensitive to vancomycin,rifampicin,sulfamethoxazle/trimethoprim and gentamicin.CONCLUSIONS The major pathogens in prostatic fluids were CNS.The chronic prostatitis causing by CNS can be treated by rifampicin,sulfamethoxazle/trimethoprim and gentamicin.It is key to treatment of CP to select the sensitive and infiltrative drug for prostate.

Objective To investigate the correlation between the formation of pigmented biliary calculus and biliary H.pylori infection.Methods Bile from 35 patients with pigmented biliary calculus and 10 healthy controls was cultured for aerobic,anaerobic and H.pylori.The expression of H.pylori- DNA in bile,bile duct mucosa and pigmented calculus were determined by PCR.The expression of H. pylori associated protein in bile duct mucosa was determined by Western-blot and Warthin-Starry staining.Results H.pylori culture was negative in all bile samples.In 35 patients with biliary pigmen- ted calculus,H.pylori was detected by PCR in the center of calculus,bile and bile duct mucosa of 14.29%,31.43% and 56.67% patients,respectively.Among H.pylori-DNA positive bile samples,7 contained anti-CagA antibodies,and 6 contained Vac A.in addition to Vacuolating cytotoxin(35000), glycoprotein(30000),Urase Band Urase A.Bacteria resembling H.pylori by Warthin-Starry stainning were found in 7 of 30(23.33%)bile duct mueosal samples from patients with biliary pigmented calculus. H.pylori-DNA and its associated protein were not detected in all bile and bile duct mucosae samples from the healthy controls.Conclusions The evidence of H.pylori-DNA and its associated protein in biliary system might indicate the role of H.pylori in the formation of biliary pigmented calculus.

Objective To observe the expression of uPA, tPA and PAI-1 in whole blood of rat membranous ne-phropathy ( MN) models induced by cationic bovine serum albumin ( C-BSA) , and to explore the effect of fibrinolytic sys-tem on podocyte apoptosis and pathological changes. To explore the possible preventive and therapeutic effects and the pos-sible mechanisms of early prevention of fibrinolysis. Methods We developed a MN model with the modified Border meth-od. At the end of the 1st, 2nd, 3th, and 4th week of immunization, respectively, the levels of whole blood uPA, tPA and PAI-1 were determined by ELISA. The rat kidney tissues were examined by light microscopy and electron microscopy to i-dentify the pathological changes. The expression levels of nephrin and WTl were detected with immumofluorescence staining and their correlation was analyzed. Results Compared the treatment group with control group, the levels of whole blood uPA, tPA and PAI-1 of the model group were decreased, while PAI-1 was elevated, showing a significant difference ( P<0. 05). The degree of renal interstitial fibrosis was more serious. Correlation analysis showed that the whole blood tPA and uPA levels were positively correlated with the changes of nephrin protein expression in the kidney tissue, while the whole blood PAI-1 level was negatively correlated with the nephrin protein expression in the kidney tissue. Conclusions In the process of MN development, the fibrinolytic system may have important significance for podocyte apoptosis. Determination of early phase of MN podocyte injury may be another therapy target for prevention of the disease development, and then pro-vide new ideas for clinical research and drug development for MN.
