The purpose of education is to cultivate talents who can master the ability of self-learning lifelong. With the rapid development of multimedia technology, the knowledge carrier represented by micro curriculum plays a very important role in improving students' self-learning ability. In traditional Chinese medicine college, due to the short of time, weak learning foundation, the ability of self-learning is hard to improve in the modern medical courses such as biochemistry. This is not conducive to the cultivation of modern talents of Chinese medicine. In this paper, we chose the biochemistry teaching in TCM college as an example, and discuss how we can make the application of micro courses reasonably in the teaching process. This study was regarded as a starting to improve the students' self-learning ability effectively.

Objective To observe the effects of ICB orthopedic sole combined with rehabilitation training on balance and walking function in stroke survivors.Methods Thirty hemiplegic stroke patients were recruited and divided into a study group (n =15) and a control group (n =15) by using a random number table.Both groups took exercises based on the principles of a motor relearning program and conducted core stability control training,and the study group additionally undertook hemiplegic lower extremity weight-bearing exercises and walking with ICB orthopedic sole used in daily living.The program was administered 20 min twice per day for 4 weeks.All patients were evaluated with Rest Calcaneus Standing Position (RCSP),Malleolar Position (MP),Forefoot Position (FP),Berg Balance Scale (BBS),l0 m Maximum Walking Speed (MWS) and walking section of Motor Assessment Scale (MAS)before and after the program.Results After 4 weeks of intervention,all the measurements except the FP in both groups improved significantly,and significant differences were observed between the two groups.After 4 weeks of training,the average RCSP (1.78 ± 0.32) ° and MP (13.33 ± 2.51)° were improved significantly compared to those of the control group [(2.58 ± 0.59) ° and (12.45 ± 3.31) °,respectively].Moreover,the average BBS,MAS and MWS improved significantly compared to the control group.Conclusions ICB orthopedic sole combined with rehabilitation training can improve the weight-bearing,balance and ambulation abilities of stroke survivors.

Objective To observe the regulatory role of microRNA-1187(miR-1187)in hepatocyte apoptosis through miR-1187 targeting regulation of caspase-8 mRNA expression.Methods The acute liver failure model was established by injection of D-galactosamine plus lipopolysaccharides(LPS)in BALB/c mice.The liver tissues were collected for LNA-miRNA array analysis and functional analysis of genes targeted by miRNA.Embryonic murine hepatocyte cell line 2(BNL-CL2)was cultivated in vitro and treated with tumor necrosis factor(TNF)-α and D-galactosamine to induce the transfection of miR-1187 in transfected group or untransfected group.The expressions of miR-1187 and caspase-8 mRNA were detected by real-time polymeramse chain reaction(PCR)and caspase-8 protein was determined by Western blot.The apoptosis rate was detected by flow cytometry.The comparison of means between groups was done by t test.Results The miR-1187 signal was deceased with the development of acute liver failure.The 3'UTR of caspase-8 mRNA had direct binding sites with miR1187.In BNL-CL2 cell experiments,miR-1187 was down-regulated in untransfected group and decreased more slowly in transfected group(t=6.371,P<0.01).The expression of caspase-8 mRNA was up-regulated in untransfected group and increased less in transfected group(t=4.539,P<0.01).The apoptosis rate in transfected group was significantly lower than untransfected group(t=3.365,P<0.05).Conclusios miR-1187 is one of inhibitors of hepatocyte apoptosis.High expression of miR-1187 could regulate the expression of caspase-8 mRNA,thus inhibit the apoptosis of hepatocytes.

OBJECTIVETo extract and separate toxic components from Phytolaccae Radix, and to comare the changes in toxicity of Phytolaccae Radix before and after being processed with vinegar.

METHODThe mucous membrane irritation response, mouse peritoneal inflammation model and in vitro macrophages release NO model were applied to compared the changes in inflammatory toxicity of toxic components from Phytolaccae Radix before and after being processed with vinegar.

RESULTToxic components of Phytolacca Radix had significant inflammatory toxicity, which could cause conjunctival edema in rabbits, and increase of PGE2 and macrophages release NO content in peritoneal exudate in mice. After being processed with vinegar, they showed reduced irritation, which resulted in decrease of PGE2 and macrophages release NO content in peritoneal exudate in mice.

CONCLUSIONAfter being processed with vinegar, the toxicity of toxic components from Phytolacca Radix decreased obviously.

OBJECTIVETo investigate the effect of bacillus Calmette-Guerin (BCG) on Toll-like receptors (TLRs) expression and cytokine production in human bladder cancer cell line T24.

METHODSHuman transitional carcinoma cell line T24 was cultured in RPMI1640 medium with 10% FBS, BCG was added into the cell culture with various doses in bacteria-cell ratio. After T24 cells were stimulated by BCG for 1 hour, total RNA of cells was extracted. RT-PCR procedure was conducted with the primer of TLR-2 and TLR-4, and the products were analyzed with agarose gels electrophoresis. Then the expression of TLR-2 and TLR-4 in T24 cells was assessed by the analyzing system of gel imaging. After the stimulation culture for 12 hours, the supernatant of cells was collected. The levels of IL-4 and IL-12 in each sample were assayed by ELISA method.

RESULTSThe expression level of either TLR-2 or TLR-4 was increased by the stimulation of BCG in a dose-dependent manner, the effects reached the maximal level at the dose of BCG as 10 bacilli per cell. The production of IL-12 in T24 cells was also increased gradually by the stimulation of BCG in a dose-dependent manner, and the dose of BCG obtained maximal effect was 10 bacilli per cell, which is coincident with the results observed in the expression of TLRs. There was no difference showed on the production of IL-4 between T24 cells stimulated with BCG and control.

CONCLUSIONSThe stimulation of BCG not only up-regulated the expression of TLR-2 and TLR-4, but also increased the production of IL-12 in bladder cancer T24 cell line. The expression of TLRs and the production of cytokine in bladder cancer cells may be related to the BCG-induced immunol response to human bladder cancer.

OBJECTIVETo explore the effects of soothing liver and invigorating spleen recipes on lipopolysaccharide(LPS) induced hepatocyte inflammation of rats and TLR4/p38MAPK signal pathway.

METHODThe hepatocytes of SD rats were cultured and identified in vitro. The medicated serum of soothing liver and invigorating spleen recipes was prepared. The hepatocytes were treated with soothing liver and invigorating spleen recipes. Then Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression in cultural supernatants were assayed by ELISA. The expressions of Toll-Like 4 (TLR4), p38 mitogen activated protein kinases (p38MAPK) and p-p38 mitogen-activated protein kinase (p-p38MAPK) were detected by Western blot.

RESULTThe rat medicated serum of soothing liver and invigorating spleen recipes was extracted for 2-3 mL. The purified rat hepatocytes were 1.5 x 10(8)-2.0 x 10(8). The cell viability was above 95% detected by Typan blue staining. The hepatocytes were identified by immumofluorescence assay. The detection of hepatocyte cultural supernatants: compared with that of the control group, IL-6 and TNF-α expression were increased in the LPS group (P < 0.01). While compared with that of the LPS group, the expressions of IL-6 and TNF-α were decreased after soothing liver and invigorating spleen recipes intervention (P < 0.01). The detection of hepatocyte proteins: compared with that of the control group, the protein expressions of p38MAPK, p-p38MAPK and TLR4 were all increased significantly in the LPS group (P < 0.01). Compared with that of the LPS group, the protein expressions of p38MAPK was decreased significantly in SB239063 group and it was also decreased in the soothing liver and invigorating spleen recipes group, but with no significant difference. Compared with that of the LPS group, p38MAPK expression was reduced significantly in the soothing liver and invigorating spleen recipes group and the SB239063 (p38MAPK pathway inhibitor) group (P < 0.01). TLR4 protein expression was decreased markedly in the soothing liver and invigorating spleen recipes group (P < 0.01) but had no difference between the SB239063 group and the LPS group.

CONCLUSIONThe soothing liver and invigorating spleen recipes may regulate hepatocyte inflammatory injury of rats through TLR4/p38MAPK signaling pathway.
