AIM: To investigate the change of corrected vision and stereo vision in anisometropic patients after laser in situ keratomileusis (LASIK).METHODS: The clinical data of 84 cases of anisometropic children(84 eyes) were retrospective analyzed.The changes of corrected visual acuity and stereopsis of different gender,age,type of amblyopia in children anisometropic before treatment,after treatment for 3,6mo and 1a were analyzed.The stereoscopic vision correction correlation were analyzed.RESULTS: Corrected Log MAR visual acuity and stereopsis of 84 patients after LASIK surgery treatment for 3mo,and 1a later significantly decreased than before treatment (P<0.05).The corrected Log MAR visual acuity and stereopsis of male and female after treatment for 3,6mo and 1a was not statistically significant (P>0.05).Corrected visual acuity of age <30 group for 3,6mo and 1a was significantly lower than the age ≥30 group (P<0.05).After 3,6mo and 1a stereo vision with hyperopic anisometropia amblyopia decreased more than that with myopic anisometropia amblyopia(P<0.05),but corrected Log MAR visual acuity after treatment was no statistically significant difference (P>0.05).Improved correctted vision of anisometropic patients after LASIK surgery had no connection with the decrease of stereo vision(P>0.05).CONCLUSION: LASIK surgery can improve visual acuity in patients with anisometropia amblyopia,but the course of treatment of visual acuity and stereopsis affected by age and type of amblyopia.

Objective To confirm subject headings which are prepared to be added, deleted and modified in the class of traditional Chinese medicine and related disciplines (TG class) for the new edition of Chinese Traditional Medicine and Materia Medica Subject Headings (CTMMeSH). Methods Compiling principle, word frequency statistics and database retrieval results were considered. Other references, such as MeSH, were also used to help choose subject headings of TG class. Results In TG class, 35 subject headings were planned to be added, such as “medicine, traditional Korean”and“TCM constitution”;35 subject headings were planned to be deleted, such as“medicine, eastern tradition”and“meridians”;19 subject headings were planned to be modified, such as “four-constitution medicine” and “Minority Medicine”. The subject headings of “Minority Medicine”were unified to harmonize the problems of“TCM pharmacy”with other classes of subject terms. Conclusion Subject headings of TG class are chosen based on word frequency statistics. The word form are unified refer to regulation, teaching materials and documents, and should coordinate with subject headings of other classes.

The complex level of constructing biopharmaceutics classification system of Chinese materia medica CMMBCS) was the study of traditional Chinese compound, on the premise of insisting that the multicomponent simultaneous determination, when carrying out the study of intestinal permeability, the primary task was to define the source of the components that was absorbed through the intestinal wall, namely, which medicinal material the components belonged to in traditional Chinese compound. The technology of chemical fingerprint and in vitro everted gut sac model were used in this research to make multicomponent an intuitive source attribution which permeated the intestine in the classic formula Gegen Qinlian decoction, and to lay the foundation for the further qualitative and quantitative research of intestinal permeability.

Objective To determine the effect of high-intensity physical activity on bone mineral density(BMD). Methods Thirty-six female soccer players (19.56±1.46 years) with more than two years training history and at least ten months soccer training annually were recruited as experiment group. Thirty-three female sedentary college students, whose physical activities were limited to the compulsory physical education curriculum,were assigned to the control group. BMD of lumbar spine and femoral neck were obtained before and after 24 months research,using dual energy X-ray absorptiometry. Results After 24 months research, increased BMD were found in both groups. Soccer players had 2.25% increase of lumbar spine BMD(P<0.05) and 4.90% increase of femoral neck BMD(P<0.05). Sedentary college students had 0.89% increase of lumbar spine BMD(P>0.05) and 2.03% increase of femoral neck BMD(P>0.05). Compared with sedentary college students,Lumbar spine and femoral neck BMD in soccer players were significantly higher(P<0.05) after 24 months research. Conclusion Long-term soccer training had the effect of greater acquisition of BMD.

“Multi-component Chinese medicine” was derived from effective clinical prescriptions, which is similar to natural medicines, and its form is similar to the fixed-dose compounds. The adaptable indications mainly cast chronic, intractable, and complex diseases. Its research targets of pharmacology mostly are diseases, symptoms or pathological process. Vivo and vitro experiments can be used in its researches. Its dose-effect relationship mostly shows non-linear relationship, and three elements (dose, efficacy and syndrome) are involved. However, the comprehensive evaluation method is still in the exploratory stag. In the safety evaluation, there were few general pharmacological researches, and the basis of toxicity and the relationship between amount and toxicity need further study. In combined optimization aspect, including identification of components and component ratio optimization, many methods have been developed, but it still needs to be developed in theory and systemic integration. Pharmacological mechanism researches focus on the multi-component, multi-target, multi-pathway, and multi-pharmacodynamics aspects, combined with new ideas and new technologies, such as systems biology, network pharmacology, etc. But as multi-component medicine, it should also be studied about the correspondence and network relationships of component and target, with a purpose to explain the contribution of each component in overall mechanism.

BACKGROUND:In perioperative period of total knee replacement in elderly patients, it is crucial to maintain the normal function of blood coagulation. However, many factors may influence coagulation function of patients in perioperative period. Of them, anesthesia is an important factor. Different anesthesia methods wil produce different effects on blood coagulation. Appropriate anesthesia methods should be selected in the clinic to maintain the stability of coagulation function. OBJECTIVE:To explore the effect of application of general anesthesia and epidural anesthesia in elderly knee replacement and the effects on the function of blood coagulation. METHODS:A retrospective analysis was performed on clinical data of 135 elderly patients after total knee replacement in Dongying Hospital of Shandong Provincial Hospital Group from September 2012 to September 2013. Al patients were divided into control group (67 cases;general anesthesia) and observation group (68 cases;epidural anesthesia) according to the mode of anesthesia. Coagulation indexes and D-dimer levels were observed before anesthesia, 6 hours after anesthesia, and 1 day after replacement in both groups. The incidence of deep venous thrombosis was measured and compared between the two groups in 12-month fol ow-up.
RESULTS AND CONCLUSION:Through the statistics and comparison, no significant difference was detected in blood coagulation indexes at different time points in the two groups (al P>0.05). However, significant differences in D-dimer levels were detectable between the two groups at 6 hours after anesthesia and in the morning at 1 day after replacement. D-dimer levels were significantly lower in the observation group than in the control group (al P<0.05). The incidences of deep venous thrombosis were 3%and 21%in the observation and control groups, respectively, showing significant differences (P<0.05). These results suggest that epidural anesthesia during elderly totak knee replacement obtained good effects, and could maintain stable coagulation function.
