ABSTRACT:Objective To validate that relaxin can resist hepatic fibrosis at the cellular level and explore its molecular mechanism in order to provide experimental basis for the treatment of liver cirrhosis.Methods Cultured HSC-T6s were treated with different concentrations (20,50 and 100 ng/mL)of recombinant human relaxin-2 (RLX-2).The proliferation of HSC-T6 was measured by MTT colorimetric assay.The content of type Ⅰcollagen in the cell culture supernatant of each group was detected by ELISA at 48 h of drug intervention;RT-PCR was used to detect the mRNA expressions of CTGF and TGF-β1 in HSC-T6 at 48 h of drug intervention.Results RLX-2 inhibited the proliferation of HSC and reduced type Ⅰ collagen content of HSC cells.It also inhibited the CTGF mRNA expression of HSC,but did not have a significant effect on the expression of TGF-β1 mRNA. Conclusion In the experiment of culturing HSC-T6 in vitro,RLX-2 may play a role in rat liver fibrosis by inhibiting cell proliferation and type Ⅰ collagen and CTGF mRNA expressions.

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.

Objective To demonstrate lower limb angiography results of peripheral arterial disease (PAD) in diabetics and evaluate one-year curative effect after interventional therapy. Methods Lower limb angiography results and the efficiency of interventional therapy for 44 limbs with PAD in 38 diabetics were retrospectively analyzed. Post-treatment clinical manifestations, signs and ankle-brachial-index (ABI) at 1 week, 1 month, 3 months, 6 months and 12 months were compared with those before treatment. Clinical evaluation was divided into four grades: apparent, effective, ineffective and deterioration. Efficiency =(apparent + effective ) / total cases ÷ 100%. ABI was compared using analysis of variance. Results Lower limb angiography revealed multi-branch lesions, with multi-segmental stenoses or obstructions.Lesions involved both above- and below-the-knee arteries in 25 limbs (56. 8% ), only above-the-knee arteries in 3 limbs (6. 8% ) and only below-the-knee arteries in 16 limbs (36. 4% ). In the limbs only with below-the-knee arterial lesions, the involved artery branches were one in one limb (2. 3% ), two in six limbs ( 13. 6% ) and three in nine limbs ( 20. 5% ), respectively. The technical success rate of percutaneous transluminal angioplasty (PTA) was 91.4% ( 53/58 ) for diseased below-the-knee arteries. Among the 12 cases with foot and ankle ulcers, ulcers healed within 3 months in 9 cases; however, the other three cases suffered below-the-ankle (in one case) or below-the-knee amputation (in two cases) within 6 months. Four cases with gangrene suffered below-the-knee amputation within one month after PTA. The amputation rate was 15. 9% (7/44). At 1 week, 1, 3, 6 and 12 months after PTA, the effective rates were 79. 6%(35/44), 83.3% (30/36), 85.7% (24/28), 85.0% (17/20) and 81.3% ( 13/16), respectively; ABI values were 0. 86 ± 0. 10, 0. 85 ± 0. 10, 0. 83 ± 0. 11, 0. 79 ± 0. 12 and 0. 75 ± 0. 12, respectively.Compared with pre-PTA ABI value (0. 53 ±0. 20), post-PTA ABI value was significant higher (F=35.79,P < 0. 05 ). However, ABI value began to decline from the 6th month after PTA. Conclusions In diabetics, PAD always involves both above- and below-the-knee arteries. PTA is a feasible and effective revascularization therapy, which could improve the clinical signs and symptoms of lower limb ischemia in diabetics with PAD. The clinical effect is satisfactory during short-term follow-up.
