Traditional Chinese medicine emphasizes the overall state of health, pays attention to individual health condition, highlights maintaining health rather than diseases, shows the clinical effectiveness with flexible treatment. It is the unique resource of health service in our country. Currently, the qualification and certification of traditional Chinese medicinewere only applied in medical practitioners of traditional Chinese medicine and Gua sha.This led to the status quo of vacuum to the traditional Chinese medicine in the fields of access system and standardization. Thus, it is urgent to unify and standardize the access and qualification traditional Chinese medicine, in order to TCM inheritance and development. The establishment of the system should be based on clinical effect and difference among the clinical application. The system can be divided into easy, middle and senior level TCM therapist. TCM therapist with different levels can apply the qualification and certification based on their own levels.

With the rapid development of medical imaging equipment, the higher requirement for the practice skills of the medical imaging professionals has been put forward. The traditional “CT and MR diagnostics” experimental teaching has some disadvantages, such as poor quality of images, imbalance of teaching resources, students' lack of practical skills training, no reflection of the practi-cal skills in the course examination and so on. They are not conducive to the cultivation of talents. Aimed to improve the experimental teaching quality of the course and students' practical skills, the reformative teaching method and means have been carried out, such as improving the laboratory facil-ities , composing experimental guidance , encouraging students to learn actively , strengthening the examination of practical skills, cultivating teachers in many different ways and so on. Through the survey, 92.9% of the students expressed satisfaction with the experimental course teaching reform. These measures will also be used in the teaching of all the sub courses of medical imaging diagnostics to promote the medical imaging professional training.

Objective: To observe the effect of the acupuncture plus medication on the expression of silent information regulator of transcription 1 (SIRT1) and transcription factor forkhead box protein O3a (FOXO3a) in the hippocampus, the malondialdehyde (MDA) content, and the superoxide dismutase (SOD) activity of rats with Alzheimer disease (AD), and to explore the possible mechanism of combining acupuncture and medication in improving AD-related neurological symptoms. Methods: Sixty male Sprague-Dawley rats were divided into a normal group, a model group, an electroacupuncture (EA) group, a drug group, and an acupuncture-medication combined group by the random number table method, with 12 rats in each group. The model was established by micro-injection of streptozotocin into the bilateral lateral ventricles. After successful modeling, rats in the EA group received EA at Zusanli (ST36) and Dazhui (GV14), those in the drug group received intragastric administration of resveratrol at a dose of 44 mg/(kg·bw), and those in the acupuncture- medication combined group received the combined intervention of EA and resveratrol. Rats in each group received intervention once a day for 4 consecutive weeks. Morris water maze was used to detect the rat behavioral changes. Nissl staining method was used to observe the cell morphology and changes in the number of rat hippocampal neurons. Western blotting and immunohistochemical staining methods were used to observe the expression changes of SIRT1 and FOXO3a. The thiobarbituric acid method was used to detect the MDA content. SOD activity was determined by the hydroxylamine method. Results: Compared with the normal group, the escape latency was significantly prolonged (P<0.05); the percentage of stay in the target quadrant was reduced (P<0.05), the hippocampal neuronal cells were shrunken, nucleoli were unclear, and cell number was reduced (P<0.05); the SIRT1 expression and SIRT1 positive cell number were decreased, while the FOXO3a expression and FOXO3a positive cell number were increased significantly (P<0.05); the MDA content was increased significantly, and the SOD activity was decreased significantly (P<0.05) in the model group. Compared with the model group, the escape latency was shortened (P<0.05); the percentage of stay in the target quadrant was increased (P<0.05); the shape and number of hippocampal neurons tended to be normal (P<0.05); the SIRT1 protein expression and the SIRT1 positive cell numbers were increased, the FOXO3a protein expression and the FOXO3a positive cell number were decreased (P<0.05); the MDA content was significantly decreased, and the SOD activity was significantly increased (P<0.05) in the EA group, the drug group, and the acupuncture-medication combined group. The changes in the acupuncture-medication combined group were more obvious (P<0.05). Conclusion: Both EA and resveratrol improve the learning and memory ability of AD rats by regulating the expression of SIRT1 and FOXO3a and improving the levels of MDA and SOD in the hippocampus and protect the hippocampal neurons, while the combined use of EA and medication is more effective than EA or resveratrol alone, suggesting that this combined treatment is more effective in AD treatment.

Objective To evaluate the effect of pneumatic ureteroscopic lithotripsy(URSL) for ureteral calculi.MethodsA total of 378 cases of ureteral calculi received URSL in our hospital by using F8/9.8 Wolf rigid ureteroscope and EMS Ⅱ pneumatic lithotripter(Switzerland).Among the cases,213 had calculi at the left side,158 at the right side,and 7 at the both sides;81 had the stones in the upper ureter,146 in the middle segment,and 158 in the lower part.Results In the cases,313 patients(320 sides) were cured after the first operation with a success rate of 82.8%(313/378).The success rates for the upper,middle,and lower ureteral calculi were 60.5%(49/81),84.2%(123/146),and 93.7%(148/158),respectively.The stones were removed completed in 1 to 8 weeks after the procedure.Fifteen patients were converted to an open surgery.In 3 patients,the URSL were stopped due to failure in placing the ureteroscope.The main postoperative complications in our series included perforation of the ureter(8 cases) and fever(13).Conclusions USRL is a safe,minimally invasive,and effective treatment.It should be the first choice for middle and lower ureteral calculi.

Qualitative and quantitative analyses of biological samples containing drugs, toxicants and endogenous substances play an important role in the researches of life sciences, as well as in new drug discovery and development. Biological samples are characterized by complex matrix, multiple endogenous interferences, significantly lower concentrations of measured analytes compared to endogenous components and small sampling volume. Consequently, it often requires bioanalysis methods with superior specificity, high sensitivity and good reproducibility. The two-dimensional liquid chromatography (2D-LC) technique, which allows for high peak capacity, significant reduced matrix effect and carryover of complex matrix samples and automated sample pre-treatment and analysis, has been the powerful solution to the separation and analysis of biological sample and widely applied to environment, food and pharmaceutical analysis. On the basis of introduction of the principle and equipments of 2D-LC, the application of this technique in the pharmacokinetics, toxicological and biological study was reviewed.
