OBJECTIVETo explore the effect of Bushen Gujin Recipe (BGR) on serum and synovial expression of interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α) in knee osteoarthritis (KOA) model rabbits.
METHODSTotally 36 8-month-old healthy male New Zealand white rabbits were randomly divided into 4 groups, i.e., the normal control group, the model group, the Western medicine group (Meloxicam, at the daily dose of 6 mg/kg), and the TCM group (BGR, at the daily dose of 53 g/kg), 9 in each group. Modeling was performed in all rabbits except those in the normal control group by using Hulth A method. All medication was performed for 8 consecutive weeks. Contents of IL-1 and TNF-α were detected using ELISA from serum, partial synovial tissue of the front knee joint, cartilage and subchondral bone of the medial femoral condyle.
RESULTSThe joint space became narrowed in the Western medicine group, ranging between the model group and the TCM group. The articular surface was rough with obvious osteophytes. The joint space was slightly narrower in the TCM group; the articular surface was slightly rough with mild osteophytes. Compared with the normal control group, contents of IL-1 and TNF-α in serum and synovial increased in the model group (P < 0.01). Compared with the model group, contents of IL-1 and TNF-α in serum and the synovial fluid decreased in the two treatment groups (P < 0.01). There was no statistical difference in contents of IL-1 and TNF-α between the Western medicine group and the TCM group.
CONCLUSIONBGR promoted the synthesis of cartilage matrix and carti- lage repair through inhibiting the secretion of IL-1 and TNF-α, and prolonging cartilage degeneration.

Objective To discuss the effect and application value of applying the master teacher responsibility system in neurology teaching. Methods 100 five-year medical students were randomly di-vided into the experimental group and the control group with computer. Master teacher and teaching team were set in the experimental group to use a variety of teaching methods for course-teaching. At the same time, the traditional teaching method was used in the control group. After the course, theory test was arranged for the two groups blindly. Statistic tool SPSS 13.0 of t test was used to evaluate the teaching effect of these two groups. And capability-oriented questionnaire survey for experimental group was conducted to survey students' subjective assessment of their own learning. Results The experimental group students' average score of the theory examination was (73.87±7.12), while control group students' average score was (73.18± 9.94), and the difference was not statistically significant (t=0.265, P=0.792). Besides, there was no signifi- cant difference in the scores of male and female students in the experimental group either (t=0.068, P=0.947). Teaching satisfaction survey results showed that 100% (16/16) of the experimental group students believed that their ability of autonomous learning, problem analysis and team cooperation was improved significantly. Conclusion Setting up master teacher responsibility system is beneficial to strengthening teacher team and cultivating students' autonomous learning ability, and it also ensures the fairness of the exam. But it still need to be improved in the quality of teachers, quantity of students, process supervision and so on to ensure the teaching effect.

Objective To evaluate the high?risk factors for brain metastases after prophylactic cranial irradiation ( PCI), and to provide a basis for personalized treatment. Methods A retrospective analysis was performed in 188 patients with limited?stage small?cell lung cancer who received PCI in our hospital from 2005 to 2010. The Kaplan?Meier method was used to calculate the cumulative rate of brain metastases. The log?rank test and the Cox model were used for the univariate and multivariate analyses of the potential factors for the cumulative incidence of brain metastases, respectively. Results In the 188 patients, 31 ( 16?5%) had brain metastases. The 1?, 2?, and 3?year cumulative incidence rates of brain metastases were 4%, 15%, and 20%, respectively. The univariate analysis showed that staged Ⅲ disease before treatment, elevated levels of tumor markers, incomplete remission after chemoradiotherapy, and local?regional relapse were risk factors for high incidence of brain metastases ( P= 0?044, 0?037, 0?005, 0?007) . The multivariate analysis revealed that incomplete remission after chemoradiotherapy and local?regional relapse after chemoradiotherapy were risk factors for high incidence of brain metastases after PCI ( P= 0?003, 0?040 ) . Conclusions Patients with incomplete remission or local?regional relapse after chemoradiotherapy have high incidence of brain metastases after PCI. For those patients, a frequent follow?up of the central nervous system plus salvage cranial irradiation might provide an alternative to PCI.

Objective To evaluate the effect of therapeutic patient education on improving life quality of children with atopic dermatitis (AD). Methods A total of 109 children with AD were enrolled, including 53 patients in the intervention group and 56 patients in the control group. The intervention group was given therapeutic patient education in addition to routine treatment, while the control group was given routine treatment without therapeutic patient education. After three months two groups were compared with the disease severity and quality of life in children and their families. Results Compared with control group, the intervention group had significant improvements in severity of AD (P?=?0.003) and also significant improvements in quality of life (IDQOL and CDLQI) (P?=?0.004). The family life quality (DFI) of the two groups were both improved, but the difference was not signiifcant (P?=?0.492). Conclusions Therapeutic patient education can improve symptoms of atopic dermatitis, and the quality of life of children as well.

Objective To compare the effectiveness of medicated γintrauterine device (IUD) and medicated genefix IUD inserted immediately after abortion. Methods A multicenter clinical trail was performed for the study from Mar. 2012 to Jan. 2013. Totally 840 women who volunteered to participate were randomly allocated to γ-group (medicated γ IUD) or genefix-group (medicated genefix IUD) immediately after abortion. While 464 abortion women who had not used IUD or steroids contraceptive methods were chosen as control group. The effectiveness of the IUD were followed up for 1 year. All women were required to record the number of vaginal bleeding days and blood volume of vaginal bleeding within 3 months after abortion. Results At the 12th month, the expulsion was the most common reason for termination. The expulsion rates of genefix-group and γ-group were 2.48/100 women years and 3.12/100 women years, respectively (P>0.05). For the expulsion reasons, IUD moving down could account for more than seventy percent. The removal rate for IUD usage of two IUD groups were almost equal (3.91/100 women years verus 4.35/100 women years), the differences were not statistically significant (P>0.05). At the 90th day after abortion, comparing with control group, the bleeding and (or) spotting days of genefix-group and γ-group extended by 3.9 and 2.6 days respectively, the differences had statistical significance between the three groups (P<0.05). Among the bleeding and (or) spotting days, spotting days prolonged significantly. At the 12th month, spotting days of genefix-group andγ-group were (9.2±5.9) days and (8.5±4.6) days respectively, more than (5.2 ± 4.0) days of control group. The differences had statistical significance between IUD with control group (P<0.05), and had not between the two kinds of IUD (P>0.05). Conclusion The insertion of medicated genefix IUD and medicated γ IUD immediately after abortion is safe, feasible, has slight side effects and could be effective contraception.
