AIM:To set up the quality standard for Fuyang Jiedu Granules(Radix Sutellariae,Herba Scute-(llariae) Barbatae,Herba Epimedii,etc.). METHODS: Radix Scutellariae,Herba Scutellariae Barbatae and Herba Epimedii in preparation were identified by TLC.The content of baicalin was determined by HPLC on Agilent Eclipse XBD-C_(18) column. The mobile phase was methanol-phosphoric-water(47∶53∶0.2).The detection wavelength was at 280 nm. A Shim-pack VP-ODS column was used to determine icariin.The mobile phase consisted of 0.32% phosphoric acid-acetonitrile(75∶25).The detection wavelength was 270 nm. RESULTS: The spot on the thin layer plate was clear.The negative contral was not disturbed.The linear range of baicalin was in the range 0.122 12 ?g to 0.606 ?g.The average recovery was 99.59% with RSD of 2.16%.The linearity range of icariin was in the range 0.201 6 ?g-1.008 ?g.The average recovery was 99.49% with RSD of 1.31%.(CONCLUSION:) The methods are specific,simple,fast and accurate,and can be used for quality control of Fuyang Jiedu Granules.

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.

6. Discrimination of Periplaneta americana and other insectivorous herbs by FTIR spectroscopy combined with chemometrics
Chinese Traditional and Herbal Drugs 2020;51(11):3045-3050
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.

Objective To screen college students contacts of tuberculosis index cases among colleges located in Haidian District,Beijing,so as to provide evidence for the modification of screening strategies for college students.Method The purified protein derivative test (PPD) and chest X-ray examination were carried out in colleges,located in Haidian District from March 2015 to March 2016.The basic demographic characteristics,tuberculosis infection and detection of patients,etc were analyzed.Results A total of 88 cases of tuberculosis index cases were diagnosed,and 3 604 college students contacts were detected 16 pulmonary tuberculosis cases were detected among close contacts,and all patients were negative,the detection rate was 443.95/100 000.Among the 3 604 close contacts,the positive rate of PPD was 8.32%.With the increase of the diameter of the PPD reaction,the detection rate of tuberculosis patients increased significantly (xtrend =8.06,P <0.001).During the period of outbreak,the PPD positive rate and the detection rate of patients were significantly higher than that of non-outbreak period,and the difference was statistically significant(all P <0.05).Conclusions It is necessary to strengthen the screening of tuberculosis among college students,and to find out the infected persons and patients as early as possible,so as to prevent the outbreak of tuberculosis.
