This paper describes the anti-inflammatory, antipyretic and analgesic effects of Sudoxicam ( Sud) synthesized by Shenyang Pharmaceutic College.Sud is found to possess significant anti-inflammatory, antipyretic and analgesic quality in such animal models as carrayeenan-induced paw oedema ( ED50=5.26mg/kg ) , tylolinduced ear oedema in mice, adjuvant-induced arthritis in rats, yeast-induced fever in rats, acetic acid-induced arithing ( ED50= 5.0mg/kg ) and hot plate-induced pain reaction in mice.

The acute iv and ig LD50 of sudoxicam synthesized by Shanyan Ph-armaceutic College was calculated to be 135?10. 7 and 320 ? 96 mg/kg in mice. In polyarthritic rats, Sud at 2 and 4 mg/kg/d for 28 days did not induce changes in serum AKP, SGPT, BUN the morphal-ogic characteristics of the gastrointestinal tract, liver and kidney. In 3 dogs orally given Sud 16 mg/kg/d for 5 consecutive days, 2/3 died at days 10 to 13. In other 3 dogs given Sud 16 mg/kg/d every other day, plasma concentrations of Sud were determined by ultra violet spectrophotometry. It was found that on the days 10 to 20 , the concentration time curves had attained a intoxicant steady state with plasma sudoxicam concentrations as high as 44. 9 ? 73. 9?g/ml ,and all of them died after 17~25 days. Their bleeding time and coagu- lation time were prolonged to 2 or 3 times of the control and serum BUN was increased. In one dog autopsy revealed the interstitial inflammation of the kidney and small local necrosis of the live, but not in other dogs.Gastric ulceration in rats can be produced by the oral administration of verious doses of Sud. The UD50 of Sud was 15.47mg/kg. It was found that the gastric ulceration in rats is related to the plasma levels

Objective To examine the expression of angiopoietin-like protein(ANGPTL)3 in kidneys from children with primary nephrotic syndrome. Methods Immunohistochemistry for ANGPTL3 was performed in kidney biopsies from patients with nephrotic syndrome or hematuria, including MCD (n=31), MN(n=6), FSGS (n=6), TBMN (n=10), IgA nephropathy (IgAN) with mesangial proliferation (n=16). Normal renal tissue of 2 cases with nephrectomy for tumor were used as control. According to the episode, four groups were divided ("12 months"). The expression was quantitatively examined with IMS color image analysis system, using positive index (PI) as sediment degree of ANGPTL3 in glomeruli or tubules. Immunofluorescence for ANGPTL3 co-labeling with WT1 and perlecan was applied to show the distribution of ANGPTL3. Results (1) The PI levels of ANGPTL3 in glomeruli of MCD(7.49?1.96) and MN (6.27?0.98) were significantly higher than those of TBMN (0.02?0.001), FSGS (3.14?0.49) or normal control(0.02?0.001) respectively (all P

BACKGROUND: One unit of umbilical cord blood does not have a sufficient number of peripheral blood stem cells to meet the requirements of transplantation in adults. One solution of this problem is their ex vivo expansion, which requires not only a longer time and higher culture conditions, but also easily leads to the differentiation of stern cells, thus affecting the effects of transplantation. OBJECTIVE: To transduce human interleukin-3(IL-3) gene into umbilical cord blood CD34" cells and to observe IL-3 expression. DESIGN, TIME AND SETTING: A cell-genomics in vitro experiment was performed in the Chengde Medical College in 2008. MATERIALS: Human peripheral blood mononuclear cells (PBMC) of healthy adult were provided by Chengde Blood Center, and umbilical cord blood was provided by Chengde Maternal and Child Care Hospital. Written informed consent was obtained from each donor. METHODS: Peripheral blood mononuclear cells were isolated by Ficoll gradient centrifugation and umbilical blood CD34+ cells were isolated using immunomagnetic beads method. IL-3 mRNA was extracted. IL-3 cDNA was synthesized by RT-PCR, and IL-3 cDNA was subcloned into eukaryotic expressing vector pcDNA3. In the experimental group, pcDNA3/IL-3 vectors were transduced into umbilical cord blood CD34+ cells, while in the control group, transfection was not performed. MAIN OUTCOME MEASURES: Detection of IL-3 level in umbilical cord blood CD34" cells suspension using ELISA kits. RESULTS: Theoretically, the amplified IL-3 cDNA was 616 bp, and actually, after agarose gel electrophoresis, the PCR products exhibited a strip with expected size under ultraviolet ray. Extraction of IL-3mRNA was successful and reversely transcripted cDNA was complete. A 616-bp inserted fragment was observed by agarose gel electrophoresis after double digestion with BamH Ⅰ and Xba Ⅰ, and it was the same as IL-3 sequence. Within 1-7 days after transfection, IL-3 level in the umbilical cord CD34+ cells suspension was significantly higher in the experimental group than in the control group (t = 3.46, P < 0.05). CONCLUSION: IL-3 cDNA was successfully cloned, and eukaryotic expressing plasmid pcDNA3/IL-3 that could be effectively expressed within short term in umbilical cord CD34+ cells was successfully constructed.

This paper is to study the feasibility of Chinese female pilot to fly fighterplane considering their physiological and biochemical tolerability to altitude anoxia. The altitude anorexia was simulated on the ground in female pilot and their electrocardiograph, heart rate, blood oxygen saturation, blood pressure, blood uric acid(BUA), blood lactic acid(BLA), creatine kinase(CK) and aspantic aminotransferase(AST) were measured before and after flying, and the results were compared with that in the male pilots. There was no difference in electrocardiograph, heart rate, blood saturation, blood pressure, Cr, CK, BUA and AST in both sexes, but the Hb level was higher in female pilots than that in male ones( P

Objective To compare the diagnostic value of high frequency ultrasound,mammography and breast blood-oxygen function imaging system in diagnosis of breast masses.Methods The images of 89 breast masses by high frequency ultrasound,mammography and breast blood-oxygen function imaging system were reviewed.The study compared the sensibilities and specificities of the three methods in the masses and analyzed their cause of missed diagnosis.Results The sensitivity of the diagnosis of breast cancer by high frequency ultrasound,mammography and breast blood-oxygen function imaging system were 80.00％,70.00％ and 50.00％,respectively.The specificity of the diagnosis of breast cancer by them were 94.94％,98.73％ and 97.47％,respectively.There were sigmfiacant differences in diagnosis of breast benign lesion among the high frequency ultrasound,mammography and breast blood-oxygen function imaging system.The sensitivity of high frequency ultrasound in detecting fibroadenoma of breast was 98.11％ higher than the other methods.Mammography was insensitive to the benign breast lesions,but its specificity was high.Conclusions High frequency ultrasound,mammography and breast blood-oxygen function imaging system are the highly effective diagnostic tool for breast cancer,but the diagnostic value of mammography and breast blood-oxygen in breast fibroadenoma and in cystic disease of breast aren' t high.Breast blood-oxygen function imaging system can enhance the accuracy of the diagnosis of mammary inflammation.

Objective To explore the effects of HPV16 E6 on genes and signaling pathways in cervical epithelial cells and to screen genes associated with oncogenic transformation.Methods HUCEC models infected with HPV16 E6 were constructed,and transcriptome sequencing was performed to screen for differentially expressed genes(DEGs),which were subjected to Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment to analyze the differential signaling pathways.RT-qPCR was used to validate major differentially down-regulated expressed genes.After predicting the major differentially expressed proteins by molecular docking analysis,the expression of major differential genes in HUCEC cell model was verified by RT-qPCR and Western blotting.In addition,RT-qPCR and Western blotting were used to further verify the expression of major differential genes in cervical cancer cell lines,SiHa and CaSki.Results A total of 55 genes with more than two-fold differential expression were screened.The results centering on down-regulated genes showed that the negatively regulated differential gene was mainly enriched in redox processes;KEGG enrichment analysis revealed that it was mainly associated with carbohydrate metabolism and cancer.RT-qPCR results showed that the down-regulated differential expression trends of the selected 10 genes were basically consistent with the sequencing results.Molecular docking analysis predicted an interaction between DHRS2 and HPV16 E6,and RT-qPCR and Western blotting confirmed that HPV16 E6 down-regulated DHRS2 mRNA(P＜0.01)and protein(P＜0.05)and ETV5 protein expression(P＜0.01).In SiHa and CaSki cells,compared with the control group,the mRNA and protein expression of DHRS2 was downregulated and positively correlated with the trend of P53 protein expression(P＜0.05).Conclusion HPV16 E6 can mediate oncogenic transformation of cervical cells and promote cervical carcinogenesis through downregulating DHRS2 expression.
