Objective To study the present situation of benign prostatic hyperplasia (BPH) of male patients in geriatrics department. Methods Two thousand one hundred and twenty-five patients aged 60 years and above with BPH in geriatrics department of Chengdu, Lanzhou, Hangzhou, Wuhan, Changsha, Guangzhou, Shenyang, Shanghai, Nanjing, Jinan and Beijing were investigated using stratified cluster random sampling method. Results The constituent ratio of patients with benign prostatic hyperplasia in geriatrics department was 47.0%, and the proportions of the elderly of 60~,70~ ,80~ years old among the patients with benign prostatic hyperplasia were 18.1%,49.4 and 32.5%, respectively (x2 = 83.68, P<0.001). There was a significant difference in the occupation distribution of BPH constituent ratio: 66.4% for staffs of state organs, 18.0% for professional technical personnel and 14.7% for works and peasants (x2=410.27,P<0.001). The international prostate symptom scores (IPSS) were different among different cities (x2=101.00, P<0. 001 ). Logistic regression analysis showed that the IPSS was correlated with age and profession (age: OR= 1.029;worker and peasant as control group, working staff of state organs OR=O.707, professional technical personnel OR=0.339 ). Conclusions The benign prostatic hyperplasia is a common disease in male elderly patients in China, but the consultation rate is low. The IPSS of benign prostatic hyperplasia is correlated with age and profession. Prevention and treatment of benign prostatic hyperplasia in the elderly should be strengthened.

A reliable method for simultaneous determinition of eleven representative components (neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C, shanzhiside, geniposidic acid, genipin-1-β-D-gentiobioside, geniposide and secoxyloganin) in combination of chromatographic fingerpint analysis for Reduning injection was developed by ultra high-performance liquid chromatography (UPLC). The method was performed on an Agilent ZORBAX SB-C18 anlytical column (3. 0 mm x 100 mm, 1. 8 µm) with a guard column of Agilent UPLC Guard ZORBAX SB-C18 (3.0 mm x 5 mm) at the column temperature of 30 °C. The gradient mobile phase consisted of acetonitrile (A)-0. 1% phosphoric acid (B) with a flow rate of 0. 4 mL . min-1. The injection volumn was 2 µL. The detection wavelengths were set at 324 nm and 238 nm for quantit tive analysis and 225 nm for fingerpint chromatography. Neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C, shanzhiside, geniposidic acid, genipin-1-β-D-gentiobioside, geniposide and secoxyloganin were baseline seperated with good linearity relationships (r >0. 999) between concentration and peak areas over the linear ranges. The average recoverys of the investigated compounds were 103.5%, 100. 2%, 103. 3%, 102. 8%, 101. 3%, 102. 8%, 97. 36%, 99. 62%, 98. 16%, 102. 8%, 99. 27%, respectively. Reduning injection of forty-five batches was analyzed by UPLC finge print chromatography. Thirty batches were selected to generate the reference fringerprint chromatography with fourteen common peaks. The similarity values between the reference fringerprint chromatography and the remaining fifteen batches were higher than 0. 99. The developed method was fast, accurate and sensitive. It could be used as a reference for the quality control of multiple components determination and fingerprint chromatography for Reduning injection in future.

Objective To evaluate the diagnostic and therapeutic status of lower urinary tract symptoms(LUTS)/benign prostatic hyperplasia (BPH) (LUTS/BPH) in outpatient department for elderly patients, and to understand the patients' attitude and knowledge on the disease. Methods The investigation was conducted in 34 outpatient departments for elderly patients located in 11 cities from February to September 2008. The male patients who came to the clinic during the survey time were investigated whether they had LUTS /BPH history or not. Then some eligible patients were chosen to accept a more detailed questionnaire and BPH-related examinations. Results There were 31371 male patients who came to the clinic. 47.0% of them (14748 cases) had the history of LUTS / BPH, and 72.4 % (10678 cases) had medical or surgical treatments presently or previously, whereas 27.6% were untreated. The three most commonly performed examinations in clinical practice were urinalysis, prostate specific antigen (PSA) and transabdominal ultrasonography. In 3542 patients receiving medical investigation, 32.6% (1155 cases) were given 5a reductase inhibitor, and 35.0% (1239 cases) received a combination therapy of 5a reductase inhibitor plus a receptor blocker. 84.5 (1796 cases) and 79.0% (1678 cases) of all the patients were satisfied with the examinations and treatments respectively. Conclusions LUTS and BPH are common in outpatient department for elderly patients. There are discrepancies of examinations and medical treatments between real medical practice and international suggestion, and the patients' understanding of the disease should be improved

Two non-destructive instrumental methods, infrared spectroscopy (IR) and X-ray diffraction (XRD), were studied for quality evaluation of Lobelia chinensis Lour. (L. chinensis). We obtained the IR spectra and XRD patterns of L. chinensis collected from different sources. The similarity of samples was analyzed by cal-culating the cosine coefficient. The cosine values were in the range of 0.83–0.90, indicating that the main components of L. chinensis samples are similar. Sample L1 and L6 showed a slightly lower similarity than that of L2, L3, L4, L5 detected by the two methods, which revealed that IR and XRD methods exhibited analogous detection ability for quality evaluation of L. chinensis. The two methods could be highly re-commended as simple and rapid detection means for quality evaluation of L. chinensis.
