The concept of humanistic education is based on the concern of human beings and their abilities of development. Thus,it is an educational concept to optimize the teaching modules.It stresses the point that education must regard the develop- ment of human beings as the main line and human beings should be emphasized in education from the very beginning to the end. Case-Teaching Method which takes the students as the main part fully manifests the concept of humanistic education,in which all teaching activities and the processes closely revolve the students in order to train them to carry on their studies and to solve the problems independently.

OBJECTIVETo evaluate the effectiveness of manual therapy and traction for lumbar disc herniation and analyze the current status of this kind of randomized clinical trial (RCT).
METHODSDatabase of CNKI, VIP, WANFANG, PubMed and OVID were searched. Some relevant journals were manually retrieved. A total of 2 874 literatures on manual therapy and traction for lumbar disc herniation were collected, of which 17 articles met the inclusion criteria. The Jadad score scale was used to evaluate the quality,and RevMan5.0 was used for meta-analysis of literatures.
RESULTSThe results of the meta-analysis of all trials involved were as followed:the combined effect of the effective rate was RR = 1.10, 95% CI [1.06, 1.14], the combined effect of the cure rate was RR = 1.36, 95% CI [1.21,1.52], the combined effect of the VAS was RR = 1.37, 95% CI [1.28, 1.45], the combined effect of the JOA was RR = 4.75, 95% CI [4.40, 5.09].
CONCLUSIONThe overall quality of the current RCT researches about manual therapy for lumbar disc herniation was lower,and did not support the conclusion that manual therapy was more effective than traction for lumbar disc herniation.

In the present study, the specifically knockdown models of P-gp or MRP2 were constructed by using a series of chemically synthesized small interfering RNA (siRNA) in vitro. The expression of P-gp and MRP2 was measured by real-time PCR and Western blot, and the function was evaluated by applying P-gp and MRP2 substrate, rhodamine and methotrexate. The results showed that MRP2 siRNA-3 or P-gp siRNA-2 significantly decreased the mRNA expression of MRP2 or P-gp, the inhibition ratio was 68% or 84%; MRP2 siRNA-3 or P-gp siRNA-2 at a dose of 80 nmol x L(-1) significantly reduced the protein expression of MRP2 or P-gp at 48 h after treatment, the inhibition ratio was 62% or 70%. Meanwhile, other transporters were not influenced by siRNA. When pretreatment with MRP2 siRNA-3 or P-gp siRNA-2, the efflux of methotrexate or rhodamine decreased significantly and the intra-cellular concentration increased. The results suggested that chemically synthesized siRNA could significantly inhibit the expression and function of MRP2 and P-gp, and the model of RNAi in vitro could be used to evaluate the role of efflux transporters in transportation of drugs.

OBJECTIVETo examine the effect of docosahexaenoic acid (DHA) deficiency in brain on spatial learning and memory in rats.
METHODSSprague Dawley rats were fed with an n-3 fatty acid deficient diet for two generations to induce DHA depletion in brain. DHA in seven brain regions was analyzed using the gas-liquid chromatography. Morris water maze (MWM) was employed as an assessing index of spatial learning and memory in the n-3 fatty acid deficient adult rats of second generation.
RESULTSFeeding an n-3 deficient diet for two generations depleted DHA differently by 39%-63% in the seven brain regions including cerebellum, medulla, hypothalamus, striatum, hippocampus, cortex and midbrain. The MWM test showed that the n-3 deficient rats took a longer time and swam a longer distance to find the escape platform than the n-3 Adq group.
CONCLUSIONThe spatial learning and memory in adult rats are partially impaired by brain DHA depletion.

OBJECTIVETo detect the effects of lumbar vertebrae Gucuofeng on the substance P content of hypothalamus and dorsal root ganglia in rat models.
METHODSA hundred and twenty SPF level SD male rats with the weight of 350 to 450 g were randomly divided into rotary fixation group (RF group), simple fixation group (SF group) and sham-operation group (Sham group). The external link fixation system was implanted into the L4-L6 of rats in RF group and SF group; and in RF group, that the L5 spinous process was rotated to the right resulted in L4, L5, L6 spinous process not collinear; in SF group, the external link fixation system was simply implanted and not rotated. The rats of Sham group were not implanted the external link fixation system and only open and suture. The substance P content of hypothalamus and dorsal root ganglia were detected at 1, 4, 8, 12 weeks after operation.
RESULTSSubstance P content of hypothalamus in RF group and SF group was lower than Sham group at 1, 4, 8 weeks after operation (P<0.05). Substance P content of dorsal root ganglia was higher than Sham group at 1, 4, 8, 12 weeks after operation (P<0.05). There was no significant differences in the substance P content of hypothalamus among three groups at 12 weeks after operation (P>0.05).
CONCLUSIONLumbar vertebrae Gucuofeng can inhibit the analgesic activity of substance P in hypothalamus and promote the synthesis and transmission of substance P in dorsal root ganglia, so as to cause or aggravate the pain.

OBJECTIVETo summarize and analyze the clinical indication, surgical techniques and results of percutaneous antegrade Kirschner pinning in the treatment of proximal fracture of humerus.
METHODSThirty-two patients with displaced fractures of the proximal humerus were treated with 2 to 3 Kirschner wires by percutaneous antegrade transfixation. Among 32 casas, there were 7 male and 25 female, with a mean age of 49.25 years (range, from 28 to 75 years). According to the Neer fracture classification, there were 20 cases of 2-part, 9 of 3-part, and 3 of 4-part fractures.
RESULTSAll patients were followed up for 8 to 34 months with an average of 13.5 months. According to Constant-Murley evaluation, the results were excellent in 21 cases, good in 9, fair in 2.
CONCLUSIONPercutaneous antegrade transfixaton is a good technique for the management of displaced 2-part fractures of the proximal humerus and also alternative to 3-part or 4-part fractures.
