ObjectiveTo explore the effect of guided learning in the eye optical applied optics teaching.Methods30 students of Grade 2013 were chosen as experimental group which was given guided learning teaching, and other 30 students of Grade 2013 were chosen as control group which was given used traditional teaching. In the guided learning teaching, self-study and practice students were re-quired to master the key and found the difficulties in the course firstly, answering questions after the group discussion. Then teachers focused on parsing the teaching materials. By the repeated communication and practice students mastered knowledge finally. The control group used the traditional teaching method which was based on the teacher's lecture. Through comparing the theory examination scores, practical as-sessment grades and questionnaire of the students self-assessment, teaching effect based on guided learn-ing was evaluated. Normal distribution measurement data was showed by standard deviation, T test was used in two independent sample measurement data; The count data was showed by rate, using Chi-squared test whichα=0.05.ResultsIn experiment group,the theoretical examination average score was(78.35±7.14) points, while in control group, the average score was(69.15±8.88)points. There were significance differ-ences between the two groups(t=-4.339,P=0.000). The experimental group practical assessment grades and the self-assessment score were superior to control group, and the difference has statistical sig-nificance (P<0.05).ConclusionGuided learning teaching can guide the students to obtain and master relevant knowledge independently, fully arouse their initiative of learning and improve their ability to analyze and solve problems, which can help reach a good teaching effect.

OBJECTIVE:To provide reference for rational use of polycystic ovary syndrome(PCOS)drugs. METHODS:The utilization of PCOS drugs in our hospital during Jan.-Dec. 2013 were analyzed in respects of consumption sum,DDDs,sorting and so on. The rationality of prescription was analyzed according to guidelines and drug package inserts and so on. RESULTS:There were 1 551 prescriptions,involving 76 kinds of drugs,and their total consumption sum was 181 072.90 yuan. Main types of drugs were hormone related drugs (accounting for 81.37% of prescription frequency,73.51% of consumption sum) and Chinese patent medicine (accounting for 15.41% of prescription frequency,19.43% of consumption sum). Top 5 hormone drugs in the list of DDDs were Ethinylestradiol and Cyproterone acetate tablets,Metformin hydrochloride enteric-coated tablets,Progesterone soft cap-sule,Dydrogesterone tablets and Progesterone soft capsules. Top 5 Chinese patent medicines in the list of DDDs were Kuntai cap-sule,Yougui capsule,Huanshao capsule,Jiawei xiaoyao capsule and Nvjin capsule. Single drug accounted for 72.08% in prescrip-tion. The proportion of irrational drug use was 1.69%. CONCLUSIONS:The application of drug in patients with PCOS is reason-able generally. Some prescriptions are unreasonable,mainly manifesting as incomplete clinical diagnosis,irrational usage and dos-age. Pharmacists should strengthen prescription verification and intervention.

Mammalian target of rapamycin(mTOR)locates at the downstream of phosphatidylinositol 3 kinase(PI3K)-protein kinase B(Akt)cell signal transduction pathway. Studies find that the abnormal activa-tion of this pathway is correlated with the endocrine and drug resistance of anti human epidermal growth factor receptor-2(HER-2)target therapy in breast cancer. The combination with mTOR inhibitors based on the past traditional drugs can block the pathway and reflect a favourable application prospect in preventing the develop-ment of resistance and restoring the initial sensitivity on tumor cells. mTOR inhibitors are expected to be the new hope for the treatment of breast cancer.

Objective:To investigate the clinical features of ocular involvement and the application of Rose criteria in patients with relapsing polychondritis (RP).Methods:The data from RP patients with ocular involvement were collected and analyzed. Patients included must have at least one major criteria of Michet criteria and the application Rose criteria was also investigated. Demographic data of these patients was presented as percentages. The difference between types of disease onset was tested by Mann-Whitney U and comparison among groups was tested by False Discovery Rate. Results:A total of 192 patients were enrolled 98 males and 94 females. The mean age of disease onset was (42±14) (0.5-79) years old, the median disease duration (DD) was 13(0.5, 600) months. The median RP disease activity index (RPDAI) was 39(9-74) and the median RP organ damage index (RPODI) was 2.5(0.1, 108). The median RP damage index (RPDAM) was 3(1-6). The statistical significant difference was identified in median DD between groups of nose and pinna ( Z=10.775, P<0.01), nose and OEH ( Z=9.277, P<0.01), in RPODI between groups of nose and pinna ( Z=7.999, P=0.031), nose and and extra-cranial organs ( Z=8.115, P=0.030) and eye and airway involvement of RPDAM could be seen between groups ( Z=7.683, P=0.037) respectively. Ocular involvement(50.0%), auricular chondritis(21.4%) and airway chondritis(13.5%) were the top three most common symptoms at disease onset. The ocular involvement(100%), airway chondritis (75.0%) and inner ear involvement(69.3%) were the top three most frequent affected organs. All parts of eye could be involved in RP ocular damage. Single-organ involvement was 59.9%; and multi-organ involvement could be seen in 40.1% patients. Diagnostic strength was enhanced by application of Rose criteria in 171 cases fulfilled Michet criteria and 21(10.9%) cases partially fulfilled Michet criteria fulfilled Rose criteria. Active screening for organ (especially inner ear and airway) involvement would improve the rate of early diagnosis. The pinna and airway involvement suggested nose and middle-ear might be involved. Conclusion:Ocular involvement in RP can involve all parts of the eye ball. Examining the inner ear and airway may help to confirm the diagnosis. It is worthy to apply this to clinical practice.
