BACKGROUND:Shengjiyuhong ointment has been reported to inhibit hypertrophic scarring. OBJECTIVE:To verify the effects of Shengjiyuhong ointment on hypertrophic scarring of in a rabbit ear model. METHODS:Each ear of thirty-six Japanese rabbits was used to make four 1-cm-diameter circular ful-thickness skin wounds with the entire perichondrium removed. Final y, 288 wounds were made and randomly divided into 6 groups:model, negative control (no drugs were administered), low-, moderate-, high-crude herbal dose drugs (Shengjiyuhong ointment was administered topical y at concentrations of 8.39%, 25.18%, and 75.54%), and positive control (recombinant bovine basic fibroblast growth factor was administered topical y). Shengjiyuhong ointment was administered twice daily til wound healing. The wounds were evaluated by the Vancouver scar scale (VSS). Scar elevation index (SEI) of scar specimens was calculated under a microscope at 40× magnification. mRNA expression levels of type I and III col agen, connective tissue growth factor, fibronectin, andα-smooth muscle actin (α-SMA) were determined by fluorescent quantitative PCR. Protein expression levels of type I and III col agen andα-SMA were detected by western blot assay.α-SMA immunoreactivity was determined by immunofluorescent staining. RESULTS AND CONCLUSION:VSS scores and SEI were significantly increased in each group at 30 days (P<0.05). VSS scores and SEI were significantly decreased in the moderate-and high-crude herbal dose drug groups and positive control groups compared with the model, negative control, and low-crude herbal dose drug groups (P<0.05 or P<0.01). mRNA expression levels of type I and III col agen, connective tissue growth factor and fibronectin, and protein expression levels of type I and III col agen andα-SMA were significantly inhibited after moderate-crude herbal dose Shengjiyuhong ointment and positive drug treatment (P<0.01). These findings suggest that Shengjiyuhong ointment can reduce hypertrophic scars by inhibiting fibroblast proliferation and col agen deposition.

Medical parasitology education has been facing some difficulties because it is a course of wide range lacking clini?cal cases and concerned specimens of parasites currently. In addition its relationship with life is not closely enough. All these reasons may impact the effect of class education negatively. Therefore it is important to increase the vitality of parasitology edu?cation and diversify the instructional mode by using the resources from Internet. In recent years the Discovery Channel has up?loaded a documentary Monsters Inside Me online. This documentary is high professional and closely linked with parasitology. It maintains numbers of clinical cases about parasitic diseases. Each episode is about 3 minutes and shortly enough to be intro?duced into class teaching. However this resource has not been fully used in domestic temporally. We found that direct introduc?tion of the documentary into class teaching can enrich teaching forms to attract learning interest of students and finally improve the teaching effect of class. Above that another popular documentary A Bite of China involves many related knowledge points of parasitology. The appropriate usage of the knowledge can build up close linkage between book and life which is extremely help?ful to give students a deep impression of parasitology. In brief it is our strong recommendation to introduce the documentary Monsters Inside Me into class.

Objective To evaluate effects of Lycium barbarum polysaccharide (LBP) on expression of vascular endothelial growth factor (VEGF) and hypoxia inducible factor-1α (HIF-1α) in ultraviolet B (UVB)-radiated HaCaT cells.Methods Conventionally cultured HaCaT cells were divided into control group and LBP groups,which were firstly treated with DMEM,12.5,25.0,50.0 and 100 μg/ml LBP solution respectively for 4 hours,and then were irradiated by UVB at different intensity of 0,20,40,60 mJ/cm2 separately.After 24-hour continuing culture,CCK-8 assay was performed to determine the cell survival rate,and an enzymatic-biochemical method to estimate the activity of superoxide dismutase (SOD).RT-PCR and Western blot analysis were conducted to measure the mRNA and protein expression of HIF-1α and VEGF respectively.Results Compared with the control group at the same UVB radiation dose,the 12.5-,25.0-and 100.0-μ,g/ml LBP groups showed different extents of increase in survival rates of UVB-radiated cells (P ＜ 0.05),and the 50.0-μg/ml LBP group showed the highest cell survival rate (P ＜ 0.01).Among all the LBP groups,SOD activity was highest in the 50.0-μg/ml LBP group (P ＜ 0.01).Along with the increase of UVB radiation dose,the mRNA and protein expression of HIF-1α and VEGF all gradually increased.Compared with the control group,the 50.0-μg/ml LBP group could effectively reduce the mRNA and protein expression of HIF-1α and VEGF in HaCaT cells (all P ＜ 0.05).Conclusion LBP may play a role in protecting cells from UVB radiation-mediated damage,likely by influencing the mRNA and protein expression of HIF-1α and VEGF in HaCaT cells.

Objective To evaluate a normative and systematic training mode for teachers of community general practice.Methods A total of 16 general practice teachers,who came from Fenglin community health service centre in Shanghai,participated three-stage training mode during March 2011 to February 2012.The clinical competence evaluation and questionnaire survey were conducted before and after training.Fifty trainees trained by the teachers also received clinical competence evaluation.Results After the three-stage training,the test score in medical knowledge,physical examination and clinical skills of the teachers did not change significantly (P =0.794,0.674 and 0.326).The self assessment questionnaire survey of general practice teachers indicated a significant increase,especially in practice capability (t =-2.840,P =0.015) and overall quality (t =-3.017,P =0.011).After training by the teachers,the medical knowledge (t =-9.200,P =0.000),physical examination (t =-9.947,P =0.000) and clinical skills (t =-14.828,P =0.000) of 50 trainees increased markedly.Conclusions Differed from conventional training courses,the three-stage training enhances teaching ability and overall quality of community general practice teachers,and provides a effective training model.

Objective To investigate the change of intestinal barrier function and the protection of pentoxifylline (PTX) to intestinal barrier. Methods Fifty-four SD male rats were randomly divided into 3groups, including sham operation group, ANP group, PTX group. ANP rat model were induced by retrograde injection of 5% sodium taurocholate into pancreatic and bile duct. Rats in sham operation group underwent operation without injection of taurocholate. After ANP induction, the rats in PTX group received PTX at a dose of 25 mg/kg weight via penis vein. The rats were sacrificed 3, 6, 24 h after operation, the serum levels of amylase, D-lactic acid, TNF-α were determined. The pancreas tissue and terminal ileum were harvested for pathological examination; ZO-1 levels of ileum epithelial tight junction were analyzed by immunohistochemistry. Results Six hours after induction, the serum levels of amylase, TNF-α, D-lactic acid in ANP group were(9141±672)U/L, (347.96±79.47) pg/ml and (10.21±1.08 ) rmg/L, which were significantly higher than those in sham operation group [(1723 ± 57 )U/L, (134.09 ± 31.36 )pg/ml and (4.33 ±0.49)mg/L, P ＜0.01]. The serum levels of amylase, TNF-α, D-lactic acid in PTX group were (7965 ± 318 ) U/L, (238.48 ± 44.35 ) pg/ml and ( 8.75 ± 1.28 ) mg/L, which were significantly lower than those in ANP group, but they were significantly higher than those in sham group ( P＜0.05 or ＜0.01). The positive rate of ZO-1 was (3.29±0.36)% in sham operation group, and it was (1.91 ± 0. 32)% in ANP group,which was significantly lower than that in sham operation group (P ＜ 0.05 ); and the value was (2.53±0.43)%in PTX group, which was lower than that in sham group, but it was higher than that in ANP group(P＜0.05).Conclusions PTX may attenuate intestinal barrier function injury by decreasing the breakdown of intestinal ZO-1.

Objective To investigate the variation of procalcitonin(PCT) in blood and tissue level of acute pancreatitis rats and probe its significant. Methods One hundred and two male Wistar rats were randomly divided into control group ( n = 6 ), lipopolysaccharide group ( LPS, n = 24 ), acute edematous pancreatitis (AEP) group ( n = 24), acute necrotizing pancreatitis (ANP) group ( n = 24), AN P + LPS group ( n = 24). Subcutaneous injection of cerulein was used for AEP induction, while ANP model was induced by retrograde injection of sodium taurocholate into the biliary and pancreatic duct. The rats were sacrificed at 3,6, 18 and 24 hours after model induction. Pancreatic tissue was harvested and the pathological scores were assessed. Levels of PCT in serum, liver, lung, spleen, pancreas, small intestine, large intestine tissue was harvested and tissue levels of PCT were determined. Results AEP and ANP models were established successfully. At 6 h, the serum levels of PCT in control group, LPS group, AEP group, ANP group and ANP +LPS group were (0.0144 ±0.0082) ng/ml, (0. 1722 ±0.0449) ng/ml,(0.4751 ±0.0572) ng/ml, (0.7070 ±0. 1040) ng/ml and ( 1. 1960 ±0.8644) ng/ml, respectively; and the difference was statistically significant (P < 0.05 ). PCT could be detected in liver, lung, spleen, pancreas, small intestine and large intestine tissue of normal rats. PCT levels in liver and pancreas of ANP group were not statistically different, but the PCT levels in lung, spleen, and large intestine tissue significantly decreased, and the corresponding values were (5.63 ±0.62) ng/ml vs. (6.85 ±0.46) mg/ml, (4.73 ±1.27) mg/ml vs. (6.88 ±0.37) ng/ml, (1.08 ±0.52) ng/ml vs. (4.12 ± 1.02) ng/ml (P <0.01 ). However, the PCT levels in small intestine significantly increased, which were (2.51 ±0.90) ng/ml vs (0.98 ±0. 12) ng/ml (P<0. 01). Conclusions Serum PCT level was associated with the severity of AP and infection; the changes of PCT levels in different tissues may be related with the changes of organ's function.
