OBJECTIVETo investigate the effect and safety of extracorporeal shock wave (ESW) in the treatment of pain symptom of type III B prostatitis.

METHODSWe treated 50 cases of type III B prostatitis by ESW once a week for 4 weeks. Then we evaluated the clinical effect and safety of the therapy based on the NIH-CPSI scores, visual analogue scale (VAS) scores, IIEF-5 scores, prostate volume and morphous, state of urination, color of urine, results of routine semen analysis, and changes of cytokines (IL-6, TNF-α and IL-1β) in expressed prostatic secretion (EPS).

RESULTSAll the patients successfully accomplished the treatment. Compared with the baseline, decreases were observed after 4 weeks of cytokine treatment in the pain scores (14. 61 ± 1. 82 vs 9. 36 ± 1. 47, P <0. 01), urination symptom scores (4. 59 ± 1. 01 vs.4. 66 ± 0. 89, P >0. 05) , quality of life scores (6. 51 ± 1. 03 vs 4. 56 ± 1. 02, P <0. 01), NIH-CPSI (25. 43 ± 1. 72 vs 18. 28 ± 2. 32, P <0. 01 ), and VAS (6. 59 ± 1. 10 vs 3. 02 ± 1. 07, P < 0. 01). The concentration of IL-6 in the EPS was significantly increased ([55.82 ± 6. 28] vs [86.59 ± 4. 55] ng/ml, P <0. 01) , while the level of TNF-α ([3.89 ± 0. 12] vs [3. 19 ± 0.22] ng/ml, P<0.01) and that of IL-1β ([3.21 ± 1.01] vs [1.48 ± 0.95] ng/ml, P< 0. 01) remarkably reduced after treatment. However, there were no statistically significant differences in IIEF-5 scores (18. 58 ± 2. 03 vs 18. 51 1. 89, P >0. 05) or various sperm parameters before and after treatment (P >0. 05). And no significant changes were observed in the prostate volume, morphous or internal echoes.

CONCLUSIONThe ESW therapy is effective and safe for the pain symptom of type III B prostatitis.

Objective:To investigate the differences in related indices of ulcerative colitis (UC) respectively induced by free drinking and intragastric administration of dextran sodium sulfate (DSS) in mice to provide experimental reference for the optimization of UC model.Methods:Totally 30 C57BL/6 mice were randomly divided into the normal control group,free drinking group and intragastric administration group with 10 ones in each.The mice drank water freely with free drinking or intragastric administration of 3% DSS solution at the dose of 4 g·kg-1·day-1 for 7 days to establish the UC model.The differences in disease activity index (DAI),histological damage sore and activity of myeloperoxidase (MPO) among the groups were compared.Results:Two mice died during the experiment in the free drinking group,and DAI of survival mice was (8.8±1.6).There was no death of mice in intragastric administration group,and DAI was (9.0±0.8),and there was no significant difference in DAI between the groups (P>0.05),while the coefficient of variation in the free drinking group was higher than that in the intragastric administration group (18.7 vs 8.6).The colonic histological damage score of the free drinking group and the intragastric administration group was 24.8±4.2 and 27.0±2.8,respectively,which was typical inflammatory change with no significant difference (P>0.05),while the coefficient of variation of the free drinking group was higher than that of the intragastric administration group (16.9 vs 10.4).MPO of the normal control group,free drinking group and intragastric administration group was (0.41±0.03),(2.32±0.34) and (2.05±0.18) U·g-1,respectively.Compared with the normal control group,significant difference in MPO was shown in the free drinking group and the intragastric administration group (P<0.01),while there was no significant difference in MPO between the groups (P>0.05),and the coefficient of variation in the free drinking group was higher than that in the intragastric administration group (14.7 vs 8.8).Conclusion:Both free drinking and intragastric administration of DSS can successfully induce the UC model in mice.Compared with the free drinking group,the intragastric administration group has low mortality rate and low coefficient of variation.Therefore,intragastric administration has more advantages than free drinking in inducing the UC model in mice.

With the developmetn of the medical humanistic education,more and more problems appear.The casualness of the medical humanistic curriculum,the monotony of the method of the evaluation,the insufficiency of the content,the inadequacy of the quality of the teachers,and the poor effect of the education are the factors affecting the development of our medical humanistic education.Through comparison of the humanistic education home and abroad,we find the key to these problems are the innovation of the curriculum and evaluation.

Objective: To establish a method for the identification of the Periplaneta americana and other insectivorous herbs (Scorpio and Hirudo) based on infrared spectroscopy combined with chemometrics, and to provide a basis for the identification of the P. americana. Methods: Fourier transform infrared spectroscopy was used to collect the infrared spectrum data of three kinds of insect medicine powders. After the second order derivation of the obtained spectral data, the ordinate verticalization method and standardization method were used to optimize the spectrum. The spectral data was further analyzed by chemometrics, such as hierar chicalcluster analysis (HCA), principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). Results: There were differences in the infrared fingerprints of the P. americanas, Scorpios, Leeches. The absorption peaks of the P. americanas at 1 711, 1 410, and 712 cm-1 were obvious. The absorption peaks of the Scorpios at 1 753, 1 400, 1 168, and 717 cm-1 were obvious. The absorption peaks of the Leeches at 1 558, 1 457, 1 400, and 669 cm-1 were obvious, And the leeches have no absorption peak at 1 753-1 711 cm-1. The peak shape of the three insectivorous herbs was significantly different at 1 800-1 700 cm-1. In the second derivative spectrum, the positions of the main peaks are the same, but the intensity of the common peaks is different. Using the HCA analysis method, it was found that the three insectivorous herbs could be quickly distinguished. The PCA and PLS-DA analysis methods were used to find that the three insectivorous herbs were distributed in different regions. Conclusion: Infrared spectroscopy combined with chemometrics can easily and quickly identify the P. americanas and other insectivorous herbs (Scorpios and Leeches), and provide reference for the quality control and evaluation of P. americanas.
