OBJECTIVETo study the effects of Chinese drugs based on strengthening the spleen and replenishing qi treatment rule on neoformative capillaries and fibroblast during the soft tissue repair after serious trauma in rats, so as to explore the biological basis of the TCM theory "the spleen dominate extremities and muscles" applied to the treatment of soft tissue injuries.
METHODSThe model rats were established by bleeding from femoral artery and lancing method, and the rats were randomly divided into the control group, strengthening the spleen group and activating blood and resolving stasis group. The samples were got from the tissue of the wounded area at the 5th, 10th and 15th days after oral administration of the traditional Chinese medicine. After fixation and section, the tissues were stained by CD31 and PCNA staining. The amount of the capillaries and fibroblasts in the tissue of the wounded area were observed through multi-purpose microscope (ZEISS Axioskop2). Quantitative analysis was carried out on Image-ProPlus image analyzer.
RESULTSThe amount of the capillaries and fibroblasts in the wounded tissue in the strengthening the spleen group were larger than that in the control group at the 5th, 10th and 15th day. And the proliferation speed of capillaries and fibroblasts was faster than those in the control group or the activating blood and resolving stasis group.
CONCLUSIONThe Chinese drugs according to strengthening the spleen and replenishing qi treatment rule were effective to promote growth of the granulation tissue and facilitate healing of the wounded area. And it has better effect than the treatment of promoting blood circulation and removing stasis.

The aim of the study is to investigate rat intestinal absorption behavior of three main active components, schisandrol A, schisandrin A and schisandrin B in Schisandra chinensis Baill extracts in intestine of rats. With phenol red as the indicator, in situ single pass intestinal perfusion (SPIP) model was used and the concentrations of three main active components in perfusion solution of different intestinal segments (duodenum, jejunum, ileum, and colon) were determined by HPLC in combination with diode array detection. The results showed that the absorption rate constant (Ka) and effective permeability values (Peff) of three main active components in Schisandra chinensis Baill extracts had significant difference (P < 0.05) at different concentrations of perfusion solution, the Ka and Peff first increased and then decreased with the increase of drug concentration, the middle concentration was higher than those of the other two concentrations. The saturate absorption phenomena were observed, and it suggested that the transport mechanisms of three main active components in vivo were similar to active transport or facilitated diffusion. Three active components can be well absorbed in all of the intestinal segments, while duodenum is the best absorption region. The Ka and Peff of three active components in jejunum and ileum had no significant difference (P > 0.05). The absorption of the three active components displayed significant difference (P < 0.05) at different intestinal segments of rats. Schisandrin A had the best absorption in duodenum. The Ka and Peff among three active components were sequenced as follows: schisandrin A > schisandrin B > schisandrol A in other intestinal segments, and there is significant difference (P < 0.05) between them.

BACKGROUNDMirizzi syndrome is often difficult to diagnose before surgery, and is often accompanied by extensive adhesions in the cystohepatic (Calot's) triangle and the difficulty of separating tissue can lead to bile duct injury and other intraoperative and postoperative complications. The aim of this study is to investigate minimally invasive means of treating different types of Mirizzi syndrome.
METHODSFifty-four patients diagnosed with Mirizzi syndrome were enrolled between July 2004 and May 2012. The diagnosis was further refined according to the Csendes classification. Twenty-seven patients were treated with a combination of endoscopic retrograde cholangiopancreatography (ERCP), laparoscopy, and choledochoscopy (tripartite approach group); type I in 16 cases, type II five cases, and type III in six cases. Twenty-seven patients were treated with laparotomy (routine approach group); type I in 19 cases, type II in six cases, and type III in two cases. The operation time, blood loss during operation, initiation of intake time of food, postoperative complications, and hospital stays were compared between two groups.
RESULTSAll patients were successfully cured in surgical operation. The operation time was (49.7 ± 27.5) minutes, blood loss during operation was (21.1 ± 15.9) ml, initiation of intake time of food was (6.3 ± 2.7) hours, postoperative complications were with two cases (7%, 2/27), and hospital stay was (6.7 ± 1.8) days in the tripartite approach group. In the routine approach group, the operation time was (85.1 ± 20.3) minutes, blood loss during operation was (150.3 ± 20.5) ml, initiation of intake time of food was (36.6 ± 10.3) hours, postoperative complications were with three cases (11%, 3/27), and hospital stay was (10.9 ± 3.4) days. Except for postoperative complications, there were significant differences in the operation time, blood loss during operation, initiation of intake time of food, and hospital stays between two groups (P < 0.05).
CONCLUSIONSERCP combined with laparoscopy and choledochoscopy is a safe and effective means of treating Mirizzi syndrome. The approach is minimally invasive and patients recover quickly requiring only brief hospitalization.

Objective To evaluate the role of endoscopic retrograde cholangiopancreatography (ERCP) in treatment for biliary complications of hepatic hydatid disease. Methods From October 2010 to October 2016 , 27 patients who were admitted for hepatic hydatid disease underwent therapeutic ERCP pre- or post-operation, then we retrospectively analyzed the clinical manifestations, laboratory tests, imaging examinations, ERCP methods and therapeutic effects in perioperative period of ERCP. Results All the 27 patients who underwent ERCP pre-or post-operations because of biliary complications of hepatic hydatid disease obtained good treatment effect. There were some reasons for ERCP, 12 cases for acute suppurative cholangitis and obstructive jaundice caused by intrabiliary rupture and 7 for severe jaundice compress by large hepatic hydatid cyst, whereas 6 cases for biliary fistula and 2 for biliary stricture after operation. 6 indexes including white blood cell count (WBC), aspertate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT) were significantly different between 24 hours pre- and 48 hours post- ERCP (P < 0.05), all the patients were improved after operation. Conclusion ERCP which is performed at pre- or post- operation may be an effective treatment for biliary complications of hepatic hydatid disease such as acute suppurative cholangitis, biliary fistula and stricture.

OBJECTIVETo investigate the effect of butyrylchitosan on the expression of proliferating cell nuclear antigen ( PCNA) in fibroblast proliferation of rabbit eyes after filtering operation.
METHODSTwenty-four New Zealand rabbits were randomly divided into 2 groups, with 12 rabbits in each group. Rabbits in one group received butyrylchitosan under scleral patch of trabeculectomy in right eyes and trabeculectomy in left eyes (trabeculectomy group). Rabbits in the other group received mitomycin C (MMC) in trabeculectomy in right eyes (MMC group) and without operation in left eyes. Rabbits were killed 1, 4, and 12 weeks after operations. Immunohistochemical staining was used to detected PCNA expression in fibroblast.
RESULTSAfter use of butyrylchitosan, the PCNA expression significantly decreased compared with trabeculectomy group (P < 0. 001). PCNA expression in MMC group was significantly lower than in trabeculectomy group (P <0. 001).
CONCLUSIONUsing butyrylchitosan under scleral patch of trabeculectomy decreases PCNA expression in proliferating cell and inhibits the scarring at filtering site.

OBJECTIVETo observe the effect and mechanism of Huatuo Zaizao extractum (HTZZ) on focal ischemia/reperfusion (I/R) blood-brain barrier injury induced by middle cerebral artery occlusion.
METHODSixty healthy male adult Sprague-Dawley rats was randomly divided into the sham operation group, the MCAO model group, the Tanakan (20 mg x kg(-1)) group, and high, middle and low-dose HTZZ groups (5, 2.5, 1.25 g x kg(-1)), with 10 in each group and single-dose duodenal administration. Middle cerebral artery occlusion was adopted to establish the rat focal I/R model. After ischemia for 90 min and reperfusion for 24 h, the pathological injury at the ischemia side was observed by HE staining. The blood-brain barrier structure was observed under transmission electron microscope. Expressions of G protein-coupled receptor kinases 2 (GRK2), matrix metalloproteinases 2 (MMP-2) and MMP-9 were detected by western blotting technique.
RESULTAfter 90 min MCAO/24 h reperfusion, penumbra cerebral cortical micro-vessels showed edema, mitochondrial injury, vacuolation, membrane injury and reduction. Along with the changes, sub-cells of G protein-coupled receptor kinase 2 (GRK2) in cortical penumbra brain tissues transferred from cytoplasm to membrane, with increase in expressions of MMP-2 and MMP-9. HTZZ could effectively recover cerebral micro-vascular endothelial edemaand blood-brain barrier ultrastructure injury induced by I/R, reduce expression of functional (membrane coupling) GRK2, and inhibit expressions of MMP-2 and MMP-9.
CONCLUSIONCell membrane coupling GRK2 may be the effective target of Huatuo Zaizao extractum.
