Objective: To determine the relationship of the expression of transforming growth factor ?1(TGF ?1), TGF ?2 and TGF? receptor(T?RⅡ) with the development of squamous cell carcinoma (OSCC). Methods: 40 cases of OSCC and 20 cases of normal oral mucosa were examined with SABC immunohistochemical staining for the expression of TGF ?1, TGF ?2 and T?RⅡ. Results: Semi quantitative analysis revealed that TGF ?1, TGF ?2 and T?RⅡ were expresed in OSCC and normal oral mucosa. TGF ?1, TGF ?2 were overexpressed in OSCC compared with those in normal oral mucosa, while T?RⅡ expression were reduced. Overexpression of TGF ?1, TGF ?2 and reduced expression of T?RⅡ were associated with pathological grade, clinical stage and neck lymph node metastasis( P

Objective: To detect the role of hypoxia in the regulation of vascular endothelial growth factor (VEGF) and matrix metalloproteinase 2 (MMP 2) in oral squamous cell carcinoma cell lines. Methods: Oral squamous cell carcinoma TSCCa and TNM cells were treated by hypoxia at ?=1% of oxygen for 4~12 h. VEGF and MMP 2 in the cells were quantitatively determined by enzymelinked immunosorbent assay (ELISA). The mRNA expression of VEGF and MMP 2 in the two cell lines was evaluated by semi quantitative RT PCR. Results: In both cell lines VEGF and MMP 2 were increased after 4 hour hypoxia treatment (P

Objective To observe the efficacy and safety of Shuxuetong injection combined with Edaravone in the treatment of acute cerebral infarction. Methods Seventy patients with acute cerebral infarction were randomly divided into two groups, the treatment group was given Shuxuetong injection and Edaravone, and the control group was treated by Shuxuening injection. Two groups were treated with routine therapy. ESS and ADL content changes in two groups were assessed at different point before treatment and two weeks after treatment. Results The score of ESS of two groups increased after treatment (P < 0.05) ,but that in the Shuxuetong group was dramatically increased ,showing significantly different from that in the control group(P <0.05). ADL of the two groups improved after treatment(P <0.01) ,but the increase in the Shuxuetong group was significantly compared to the control group(P <0.05). Conclusion Shuxuetong injection combined with edaravone is an effective and safe medicine in treatment of acute cerebral infarction.

Objective To explore whether or not driamycin inhibits mEC cells by apoptosis. MethodsAdriamycin was used for mucoepidermoid carcinoma cells mEC-l. Morphologic changes were observed atdifferent times by light and electronic microscope. DNA fragments were shown on agarose gelelectrophoresis. DNA content and cell cycles were analyzed by flow cytometer. Changes of intracellularcalcium ion was monitored by flow cytometer. Results mEC-1 cells presented with classic morphologicfeatures of apoptosis. Intracellular calcium ion was increased. Conclusion Apoptosis followed by thechanges of intracellular calcium ion in human salivary gland mucoepidermoid carcinoma cells is one of themechanisms of adriamycin inhibited tumor cell growth.

Objective: To study the role of transforming growth fa ctor ?1(TGF-?1) in the procession of human oral squamous cell carcinoma. Methods: Immunohistiochemical techinic was used to determine o ncogene c-myc,c-erbB2,TGF-?1 and EGFR protein expression in oral squamou s cell carcinoma cell line TSCCa and metastasis carcinoma cell line GNM treated by different levels of TGF-?1. Results: TGF-?1 showed different effects on the two cell lines. TGF-?1 significantly increased the expression of C-myc,CerbB2 and slightly enhanced TGF-?1 and EGFR protein expression in GNM cells, while TGF-?1 decreased the expression of C-myc,C erbB2,TGF-?1 and EGFR in TSCCa cells; moreover, the changes of protein ex pression of C-myc,CerbB2 were dose-dependent on TGF-?1. Conclusi on: TGF-?1 have different role in the oral squamous cell carcinoma cell lines.

Objective To investigate the change and clinical significance of serum hepcidin,serum ferritin (SF),transferrin re-ceptor (sTfR)and serum iron (SI)in patients in type 2 diabetes(T2DM).Methods 130 patients with T2DM were divided into 2 groups according to the 24 hour urine microalbumin (mAlb)quantitative:group A for trace microalbumin group 45 ca-ses (mAlb30~300 mg/24 h),group B for normal albuminuria group of 85 cases,an alternate period of 45 cases of healthy physical examination for group C (control group).Results Serum hepcidin and SF of group A (42.27±32.12 ng/ml,211.6 ±107.2 ng/ml)were significantly higher than those in group B (26.12 ± 18.36 ng/ml,179.1 ± 109.7 ng/ml)and the healthy control group (P <0.05),hepcidin and SF of group B was significantly higher than that of the control group (9.47 ±1.65 ng/ml,84.41±47.10 ng/ml,P <0.01),SI and transferrin receptor(sTfR)has no statistical significance between the three groups (P >0.05).Correlation analysis showed that patients with type 2 diabetes hepcidin was positively related with SF (P <0.05),hepcidin and sTfR,SI had no significant correlation.Conclusion These results indicated that there existed serum hepcidin and SF increased iron overload and iron metabolism disorder in type 2 diabetes.Therefore,detection of serum iron and SF can be used as a predictor of diabetes early renal damage.

Objective:To develop an HPLC-MS/MS method for the determination of rosuvastatin in plasma and study the relative bioavailability and bioequivalence of the capsules and tablets in Chinese healthy volunteers. Methods: A single oral dose (20 mg of the test or reference preparation) was given to 24 male healthy volunteers in a randomized crossover study. The plasma concentration of rosuvastatin was determined by HPLC-MS/MS. The pharmacokinetic parameters were calculated and the bioavailability and bioequiva-lence of the two preparations were evaluated by DAS 3. 0 software. Results:After a single dose, the pharmacokinetic parameters of ro-suvastatin capsules and tablets were as follows:Tmax was (3. 56 ± 1. 68) h and (3. 63 ± 1. 56) h, Cmax was (21. 17 ± 13. 74) ng· ml-1 and (26.33 ±23.22) ng·ml-1, t1/2 was (10.68 ±5.50) h and (9.04 ±6.00) h, AUC0-t was (219.31 ±146.09) ng·h· ml-1 and (252. 43 ± 194. 96) ng·h·ml-1 , AUC0-∞ was (225. 32 ± 146. 76) ng·h·ml-1 and (257. 24 ± 194. 61) ng·h·ml-1 , respectively. The 90% confidential interval of AUC0-t, AUC0-∞ and Cmax was 81. 1%-106% , 81. 8%-105. 4% and 77. 9%-104. 5%, respectively. The mean relative bioavailability of the test preparation(the capsules) to the reference preparation(the tablets) was (100. 7 ± 54. 1)%. Conclusion:The test and reference preparations are bioequivalent.
