Objective] To prove the modified Maxingshigan Decoction(modified MXSGD) intervening radiation induced lung injury(RILI) through the TGF-β/Smad signaling pathway by selectively silencing the TGF-β1 gene. [Methods] (1)Total of 18 clean SD rats were randomly divided into two groups:Chinese medicine group treated with modified MXSGD and normal control group treated with saline. The serum was made after 3 days of taking drugs to prepare medicated serum. (2) The alveolar typeⅡcells were cultured. The total dose of radiation to cell was 8Gy, frequency 3.64Gy/min. The medicated serum was given to each group respectively. (3) After silencing TGF-β1 gene with RNA interference technology, the level of TGF-β1, PAI-1, CTGFmRNA was analyzed by PCR and the protein expression of Smads was measured by Western-blot. [Results] (1) Compared with rat serum group, the expressions of TGF-β1 mRNA, P-Smad2 in 10%medicated serum group were down-regulation or deceased(P<0.05).(2) Compared with rat serum group, the transcription levels of TGF-β1, and PAI-1 and CTGF were obviously suppressed after silencing TGF-β gene(P<0.05). (3) There was no significance effect on the expression of P-Smad2, P-Smad3, PAI-1mRNA and CTGF mRNA in both 10%medicated serum+siRNA group and rat serum+siRNA group(P>0.05). (4) Compared with rat serum+siRNA, the expression of Smad6 and Smad7 was increased in 10%medicated serum+siRNA group. The differences between the two groups were significant(P<0.05, P<0.01). [Conclusion] Modified MXSGD may intervene the RILI by regulating TGF-β/Smad signaling pathway.

Objective To determine the mechanism underlying the mandibular angle enlargement and to provide a morphological basis for correcting the enlarged mandibular angle. Methods By axial computed tomography, it is possible to measure the width and length of the masseter and the medial pterygoid, the gonial angle, and the vertical height of the posterior mandible. The date were initially analysed by using a simple correctionials and indpendent sample T test. Results The distance between two Go points and gonial angle were significantly related with the thickness of masseter muscle, but the thickness of the medial pterygoid was on the contrary. There was significant differences between the group of prominence and the normal control in the gonial angle, the distance between two Go points and thickness of masseter . But there was no difference between the the two groups in the thickness of medial pterygoid. Conclusion The thickness of the masseter muscle is an important factor that affects the lower facial morphology. The hypertrophy of masserter muscle may cause the mandibular angle enlargement.

Background and purpose: E-cadherin (EC) is a type of glycoprotein, which could maintain epithelial polarity and cell-cell junction. It is thought to be associated with the development and progression of hepatocellular carcinoma (HCC). The study aimed to detect expression of uniting detection sEC and AFP before and after operation in patients, and to monitor recurrence of postoperative. Methods:The levels of sEC and AFP in 105 HCC patients were tested by enzyme linked immunosorbent assay (ELISA) and radioimmunoassay (RIA) before and after operation as well as in 70 healthy controls. Theirs correlation with clinical and pathological factors was analyzed. We analyzed the level of plasma sEC and AFP of 47 patients who had been suffered from the hepatocellular carcinoma operation and relapse. Results: The levels of sEC and AFP in HCC patients before operation were significantly higher than in controls, which declined significantly one week after operation. The sEC level before operation showed significant correlation with TNM staging (P<0.01), edmondson grade, the carcerous thrombi within the portal vein and the capsule of carcinoma (P<0.05), but not with age of patients or the tumor size (P>0.05). While AFP only correlation with TNM staging (P<0.05), not with others factors (P>0.05). When the recurrence was confirmed, the level of sEC was much higher significantly than the level postoperation (P<0.01). Conclusion:The levels of sEC in HCC patients before operation are closely related with prognosis and recurrence of HCC. The unites detection of sEC+AFP may be a predictive factor for recurrence of postoperation.

Objective To construct a recombinant plasmid DNA containing herpes simplex virus type 1(HSV-1) glycoprotein D (gD) gene.Methods The HSV-1 gD gene was obtained by polymerase chain reaction (PCR) and inserted into TA cloning vector pGEM-T, then cloned into the eukaryotic expression vector pcDNA3.1 to generate pLy-D. The recombinant plasmid pLy-D, which was confirmed by partial sequencing and restriction endonuclease analysis, was transfected into Cos-7 cells and used to inoculate ICR mice via muscular injection. Immunohistochemistry and enzyme-linked immunoabsorbent assay (ELISA) were employed to test the gD expression in transfected cells and the specific anti-HSV-1 antibody in the serum of immunized mice, respectively.Results The gD eukaryotic expression plasmid pLy-D was constructed. Using the immunohistochemistry technique, the gD expression in pLy-D-transfected cells was detected. The ELISA demonstrated that specific anti-HSV-1 antibody could be induced in immunized mice after three times injection.Conclusions We constructed HSV-1 gD eukaryotic expression plasmid pLy-D which could express gD protein in transfected cells and could induce humoral immune response in mice. This observation will be helpful in designing HSV prophylactic vaccine.
