OBJECTIVEUsing the method of bleeding from the orbital vein and lancing to make the animal model of trauma, and to observe the influence of reinforcing Qi strength spleen in the expression of bFGF and EGF in the reparative process of raw surface, in order to explore the possible mechanism of reinforcing Qi strength spleen in promoting the rehabilitation of soft tissue.

METHODSForty healthly adult SD rats were made to be traumatic model using the method of bleeding from the orbital vein and lancing. After operation, there were 33 rats survival, which were divided into the reinforcing Qi strength spleen group, the activating blood circulation to dissipate blood stasis group and the model group randomly. The raw surface and ambient normal skin were taken at the 3rd, 7th and 14th days after operation to detect the expression of bFGF and EGF by immunohistochemical method.

RESULTSAt the 3rd, 7th and 14th days after operation, the expression of bFGF and EGF in the tissue of raw surface of the reinforcing Qi strength spleen group and the activating blood circulation to dissipate blood stasis group was obviously higher than that of the model group(P < 0.05). Compared with the activating blood circulation to dissipate blood stasis group, the expression of bFGF and EGF in the tissue of raw surface of the reinforcing Qi strength spleen group was higher (P < 0.05) in the 3rd and 7th day after operation. But in the 14th after operation, there was no significantly difference between reinforcing Qi strength spleen group and activating blood circulation to dissipate blood stasis group.

CONCLUSIONThe method of reinforcing Qi strength spleen can efficiently promote the expression of bFGF and EGF in raw surface of serious soft tissue injury.

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.

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.

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.
