This paper deals with research and manufacture processes of the 8 millimeter wave therapeu- tic apparatus,the application to the clinical treatment for gastric and duodenal ulcer.

BACKGROUND: It has been proved that the application of basic fibroblast growth factor (bFGF) combined with Brucea Javanica oil emulsion can accelerate wound healing and inhibit scar formation.OBJECTIVE: To observe the effects of bFGF plus Brucea Javanica oil emulsion cream on accelerating the skin wound healing of rabbits.DESIGN: A randomized controlled observation.SETTING: Center of Biotechnological Research and Development, Jinan University; College of Pharmacy, Jinan University.MATERIALS:The experiment was carried out in the College of Pharmacy, Jinan University from June to September in 2004. Eight Beijing big-ear white rabbits (4 males and 4 females) of 2.0-2.5 kg were provided by the experimental animal center of Southern Medical University (certification number: SoKx-2002-010). bFGF sterile freeze dried powder agent,provided by Guangzhou Changsheng Gene Pharmaceutical Co.,Ltd (batch number: 20040219; specific activity was 6 000 U/bottle), was prepared to solution with water for injection before application. Brucea Javanica oil emulsion (manufactured by Zhejiang 999 Bang'erkang Pharmaceutical Co.,Ltd.) was provided by Professor Yao from staff Room of Pharmacy, Shenyang Pharmaceutical University.METHODS: The rabbits were anesthetized and disinfected, 5 round wounds with diameter of 1.8 cm and area of 2.54 cm2were induced from front to back by bilateral incision at 1.5 cm from middle spine of rabbit. The 5 wounds of each rabbit were randomly divided into bFGF-treated group (90 U/cm2), bFGF+Brucea Javanica oil emulsion group [the wound was smeared with Brucea Javanica oil emulsion (30 mg/cm2) 30 minutes after bFGF (90 U/cm2)], Brucea Javanica oil emulsion treated group [the wound was smeared with Brucea Javanica oil emulsion (30 mg/cm2)], blank emulsion group (30 mg/cm2) and blank control group (the wound was smeared with saline). The medication was give immediately after injury, and changed once a day for 16 days. At 4, 8, 12 and 16 days after injury, the wound areas were recorded with the method of hyaline membrane tracing (the wound was covered with clean saran wrap, the size of wound was traced,and then sheared to be weighed, and converted to calculate the area), and the volume of wounded cavity was measured by infusing water. At 8 and 16 days, the wound tissue was removed, stained after routine tissue sections, and the conditions of growth of granulation tissue and reepithelization on the wound surface were observed.MAIN OUTCOME MEASURE: The wound area, volume of wounded cavity, and the conditions of growth of granulation tissue and reepithelization on the wound surface were obviously at different time points after injury in each group.RESULTS:All the 8 rabbits were involved in the analysis of results. ① Wound areas at different time points in each group: The wound areas in the bFGF+Brucea Javanica oil emulsion group at 4, 8 and 12 days after medication were smaller than those in the blank control group at corresponding time points [(2.05±0.35), (1.59±0.25), (0.55±0.25) cm2;(2.53±0.30), (2.41±0.19), (1.09±0.34) cm2, P＜0.05-0.01]. The wound areas in the bFGF group at 8 and 12 days after medication were (1.71±0.31) and (0.51±0.10) cm2, which were significantly smaller than those in the blank control group at corresponding time points (P＜0.05-0.01). ② Volume of the wounded cavity in each group: The wound volume in the bFGF group at 4 days after injury was markedly smaller than that in the blank control group at corresponding time point [(0.49±0.12), (0.59±0.1) mL, P＜0.05]. The wound volumes in the bFGF+Brucea Javanica oil emulsion group at 4 and 8days after injury were significantly smaller than those in the blank control group at corresponding time points [(0.47±0.12), (0.30±0.08) mL; (0.59±0.1), (0.41±0.07) mL, P＜0.05, 0.01]. ③ Growth of granulation tissue and reepithelization on the wound surface in each group: At 8 days after injury, the inflammatory reaction was milder and fibroblasts proliferated significantly in the bFGF+Brucea Javanica oil emulsion group, and the numbers of capillary plumules and fibroblasts were significantly more than those in the blank control group. The conditions in the blank control group and blank emulsion group were generally the same that there were severe inflammatory reactions, obvious increase of granulation tissue, fewer new capillaries, and unobvious proliferation of epidermic cells. At 16 days after injury, the contraction and reepithelization on the wound surface were obvious, and the new epithelia went towards the wound center rapidly in the bFGF+Brucea Javanica oil emulsion group.CONCLUSION : The application of Brucea Javanica oil emulsion plus bFGF can obviously accelerate the repair of incised wound on the back of rabbits.

BACKGROUND: Matrigel as an extracellular matrix complex can facilitate cell proliferation, differentiation and collagen secretion in a cell culture system. OBJECTIVE: To establish a three-dimensional culture model of Matrigel combined with bone marrow mesenchymal stem cells (BMSCs) and to observe the morphology, proliferation and survival of BMSCs in the Matrigel three-dimensional culture model. METHODS: BMSCs were isolated and cultured by the whole bone marrow adherent method, followed by osteogenic and adipogenic induction and identification. The growth curve of passage 3 BMSCs was determined through the CCK-8 experiment. Passage 2 BMSCs were combined with Matrigel, and the morphology and proliferation of BMSCs were observed by hematoxylin-eosin staining under a phase contrast microscope. The viability of the cells was evaluated by the Live/Dead staining. RESULTS AND CONCLUSION: (1) BMSCs cultured by the whole bone marrow adherent method had the ability to differentiate into osteoblasts and adipocytes. (2) BMSCs exhibited an "S"-shaped growth curve, which was consistent with the growth characteristics of normal cells. (3) Under the phase contrast microscope, BMSCs cultured by the Matrigel model were extended and interconnected in a three-dimensional network growth state with good proliferation. The Matrigel gradually became soft and collapsed over time (7days) and a few cells were still in a network growth after 14 days. Hematoxylin-eosin staining results showed that the cell cytoplasm was larger at 4 days and the cells became thinned and mutually cross-linked at 7 days. (4) The active percentage of BMSCs in the Matrigel model was 92.57%, 95.54% and 97.37% at 1, 4, 7 days of culture, respectively. To conclude, BMSCs cultured on the Matrigel has good proliferation and high viability.

OBJECTIVE: To investigate the outcome of the kidney transplant recipients with different grades and stages of chronic hepatitis B virus after receiving renal transplantation for 3 years. METHODS: Thirty nine cases of kidney transplant recipients with hepatitis B virus and 20 cases of kidney transplant recipients (control group) between August 2000 and February 2002 were studied. Before the transplantation, the patients were divided into 4 groups: the mild hepatitis group (Group A, n = 8), the middle hepatitis group (Group B, n = 6), the severe hepatitis group (Group C, n =5) according to pathological diagnosis by percutaneous liver biopsy, and the control group (Group D). During the 3 year follow-up, the serum creatinine, alanine aminotransferase, g-Glutamyl transferase (GGT), total bilirubin, direct bilirubin, prothrombin time, cyclosporine trough concentration, urinary protein excretion, the HBV markers, HBV-DNA, albumin (A), globulin (G), the hepatic fibrosis markers and Child-Pugh score were studied at intervals. All patients received ultrasound examination every year. Two patients received repeated liver biopsy at the end of the follow-up in the hepatitis groups. RESULTS: The outcome of Group A and Group D was fine. In Group B, GGT level was significantly elevated (P < 0.05) sixth months after the operation, the Child-Pugh score of 2 patients were B, the liver pathohistological changes in another 2 patients were in severe stage in the endpoint. In Group C, GGT values had higher base-line (P <0.01) during the follow-up. Albumin were lower and globulin were higher than normal at the beginning of the 24th month. At the end of the follow-up, the Child-Pugh scores of all patients were B or C (B = 3, C = 2), 4 patients had end-stage cirrhosis, one died of hepatic cancer and the survival rate was 40% in Group C. CONCLUSION The outcome of the 3 groups is different. The pathohistological diagnosis by liver biopsy is important for patient selection receiving renal transplantation.
