There are few articles or reports collecting evidence about parenterally administered salvianolate from premarketing and postmarketing research or studies systematically. This article is an exact miniature of a systematical report about parenterally administered salvianolate. We analyzed information from four aspects, such as quality control reports, non-clinical premarketing safety experiments, postmarketing research (efficacy studies, hospital information system data and national spontaneous reporting system data) and literature analysis. All the four aspects build an evidence body for Kudiezi Solution in order to inform its safety use in clinical practice and further study.

BACKGROUND:Chronic venous insufficiency is a major health problem worldwide. Clinical treatments include venous valve repair and venous segment containing valve transplantation. However, these are invasive procedures, and the supply of vein containing valves is limited. Significant progress in the fields of tissue engineering and regenerative medicine has been made towards the creation of tissue engineered vascular grafts for the repair of damaged or malformed vessels. It has been reported that using tissue engineering, a tissue engineered vein containing valves constructed with self-derived endothelial cells and al ogeneic acellular matrices can provide the complex physiological valve structure and mechanical stability, but this elicited an immunogenic response.
OBJECTIVE:To create a viable and functional vein containing valves, which has the ability to grow, repair, and imitate natural tissues.
METHODS:Bone marrow mesenchymal stem cells were obtained from Beagle dogs by density gradient centrifugation and adherence methods. Bone marrow mesenchymal stem cells were cultured in vitro. Fol owing isolation and culture the cells were examined using flow cytometry and identified by direct induction towards the osteogenic and adipogenic lineages. We fabricated biodegradable venous scaffold containing valves using the method of injection molding combined with thermal y induced phase separation. Based on the self-made cast, a three-dimensional biodegradable vein scaffold containing valves was constructed from poly(lactic-co-glycolic acid). Morphological structure was tested. Bone marrow mesenchymal stem cells were used as seed cells to be seeded onto the lumen of the tissue engineered vein scaffold containing valves in vitro and then incubated for 2 weeks.
RESULTS AND CONCLUSION:Scanning electron microscopy images showed that the scaffold demonstrated sufficient porosity. Cultured cells expressed mesenchymal cellmarkers, CD44 and CD29, but did not express hematopoietic cellmarkers, CD34 and CD45 at the same time point. Scaffolds were nontoxic to cells and were favorable for the growth and migration of bone marrow mesenchymal stem cells. cells attached on the surface of poly(lactic-co-glycolic acid) scaffolds formed a confluent layer after incubation. The cellular constructs were tested in vitro, and the valve leaflets were functional y capable of opening and closing when stimulated. These results suggested that the tissue engineered vein containing valves have been successful y constructed by using a three-dimensional poly(lactic-co-glycolic acid) scaffold and bone marrow mesenchymal stem cells as seed cells. Tissue engineered vein containing valves is potential y useful for the substitution and regeneration of vein valves.

Objective To summarize the clinical experience in the replacement of the damaged sec- ond metacarpophalangeal joint with the second metatarsophalangeal joint with a pedicle of dorsal pedis artery and great saphcnous vein.Methods The damaged second metacarpophalangeal joint,distal part of the sec- ond metacarpal and proximal part of the proximal phalanx were dissected.The metatarsophalangeal joint was transferred to the region of metacarpophalangeal joint of hand.The dorsal pedis artery was anastomosed to the radial artery,and the great saphenous vein was anastomosed to the cephalic vein at anatomical snuff-box.The dissected bones of the hand removed of the cartilage of joint and soft tissue were grafted back to the donor site of the foot.Results A 5～30 month follow-up study in 8 out of 11 cases showed that satisfactory functional recovery was achieved in clinical practice.The movement of second metacarpophalangeal joint was excellent. Conclusion The function of the second metacarpophalangeal joint can be effectively recovered by the trans- fer of the vascularized second metatarsophalangeal joint.

OBJECTIVETo explore the relationship between the proliferation, differentiation of rat hepatic stem like cell line WB-F344 and cytokines in vitro.

METHODS(3)H thymidine labelling of new synthesized DNA was used to examine the mitogenic responsiveness of WB-F344 cells to cytokines, western blot was used to study the expression of cytokines receptors on hepatic stem cells, and apoptotic cells were detected by Flow cytometry.

RESULTSWB-F344 cells showed a proliferative response to the cytokines of hepatocyte growth factor (HGF), epidermal growth factor (EGF), fibroblast growth factor (FGF), Insulin at the dose of 80 ng/ml, and the relative cpm values are 982.95, 906.32, 863.98 and 968.67 respectively, while non response to interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) at the same dose, and an inhibition or apoptosis response to transforming growth factor-beta (TGF-beta) at 80 ng/ml with a 26.89% apoptotic rate. Western blot showed that there were HGF, EGF, FGF, TGF-beta receptors expressed on WB-F344 cells. When WB-F344 cells were cultured in the differential system (DMEM, 10% Fcs, HGF 10 to approximately 50 ng/ml, EGF 20 ng/ml, Insulin 1 microg/ml, Dex 1 micromol/L), the cells could differentiated into hepatocytes. In addition, HGF could scattered WB-F344 cells.

CONCLUSIONThe proliferation and differentiation of liver stem cells are regulated by various cytokines which may play an important role when liver is damaged seriously.

OBJECTIVESTo investigate the impacts of laparoscopic bariatric surgery on fasting glucagon-like peptide-1 (GLP-1) and Ghrelin level in patients with type 2 diabetes mellitus (T2DM), and the mechanism in surgical treatment of T2DM.

METHODSFrom March 2010 to August 2011, 44 patients with T2DM underwent laparoscopic bariatric, including laparoscopic Roux-en-Y gastric bypass (LRYGB, n = 14), laparoscopic mini-gastric bypass (LMGB, n = 11), laparoscopic sleeve gastrectomy (LSG, n = 9) and laparoscopic adjustable gastric banding (LAGB, n = 10). The curative effects, changes of metabolism and gastrointestinal hormones were analyzed respectively.

RESULTSWithin 6 months after surgery, the clinical complete remission of T2DM was 11, 8, 6, 3 cases in LRYGB, LMGB, LSG, LAGB group respectively; the clinical partial remission was 3, 3, 2, 4 cases respectively. The inefficacy was 1, 3 patients in LSG and LAGB group respectively. The effects of surgery within 6 months postoperative among 4 groups were different (χ(2) = 8.162, P < 0.05). The levels of body mass index (F = 275.29) and homeostasis model assessment of insulin resistance (F = 40.09) of 4 groups were declined in 6 months postoperatively (P < 0.01). The extents of decrease were no significance among 4 groups. Compared to preoperative level, GLP-1 in LRYGB ((116 ± 33) vs. (66 ± 20) ng/L and LMGB group ((103 ± 22) vs. (65 ± 16) ng/L) was higher in the first month after surgery (F = 21.76 and 139.21, P < 0.05). The changes in LSG and LAGB group were no significance (P > 0.05). The level of Ghrelin in LRYGB, LMGB, LSG group at the first week after surgery were (208 ± 79), (275 ± 102) and (258 ± 91) ng/L respectively, and they were lower than preoperative (there were (398 ± 114), (439 ± 96) and (446 ± 105) ng/L, F = 55.08, 49.96 and 46.47, all P < 0.01). But the level of Ghrelin in LRYGB and LMGB groups rebounded in the first postoperative month. The postoperative level of Ghrelin was higher in LAGB group (F = 29.24, P = 0.001).

CONCLUSIONSThere are difference efficacies and impacts on gastrointestinal hormones among different modes of bariatric surgery. The change of gastrointestinal hormones is plausible mechanism of T2DM remission after surgery.
