Objective To evaluate the safety and efficacy of transrectal ultrasound guided prostatic nerve blockade for pain control during transrectal prostate biopsy.Methods Seventy-three patients requiring systematic 13 cores biopsy of the prostate were randomized into two groups.Group A(37 cases) received an injection of 5 ml 1% lidocaine into the prostatic neurovascular bundles on each side at the base of the prostate under ultrasound guidance,and group B(36 cases) received 5 ml saline ( 0.9% sodium chloride) at the same way.Pain during biopsy was assessed using a 10-point linear visual analog pain scale immediately after this procedure.Results The mean pain scores during transrectal prostate biopsy were significantly lower in group A than that in group B( 1.1? 0.6 vs 5.9? 3.1,t= 4.81,P

Objective To evaluate the clinical value of transrectal ultrasound guided systematic 13 cores prostate biopsy. Methods A total of 160 patients referred for abnormal digital rectal examination and (or) prostate specific antigen 4ng/ml or greater underwent transrectal ultrasound guided systematic 13 cores prostate biopsy.That was,in addition to the standard sextant biopsies,cores were taken from the far lateral and middle regions of the gland as described by Eskew.Pathological findings of the additional regions were compared with those of the sextant regions. Results Of the patients 35 % had cancer on biopsy(56 /160).Of the 56 patients with prostate cancer 12(21%)had carcinoma only in the additional regions,which would be undetected on the sextant biopsy technique (P

Objective To know the drinking water safety for students and teachers in urban and rural boarding schools in Guangxi, further to prevent and control the water-borne diseases. Methods The random stratified cluster sampling method was used to select 100 schools in 10 counties of Nanning, Liuzhou and Guilin cities. The drinking water samples were collected and tested according to Sanitary Standard for Drinking Water Quality2001. The epidemic situation of intestinal infectious diseases was investigated. Results The total qualified rate of drinking water quality in 100 boarding schools of 10 counties cities was only 27.00%, as for the water supply provided for themselves with disinfection, the qualified rate was 47.37%, without disinfection, it was 16.95%. 24 outbreak events of intestinal infectious diseases occured in 100 boarding schools in 2000-2005, 2 339 of school teachers and students were attacked, including 13 outbreak events of typhoid and paratyphoid 54.17% with 1 280 cases 54.72%, 6 outbreak events of bacterial dysentery25.00% with 829 cases35.44%, 4 outbreak events of infectious diarrhea 16.67% with 225 cases 9.62%, 1 outbreak of hepatitis A 4.17% with 5 cases 0.21%. These 24 epidemic events were caused by drinking water, the morbidity was higher in the schools where there was no disinfection facility in water supply. Conclusion Some of water supply for some urban and rural boarding schools have been polluted with bacteria in Guangxi, so drinking water disinfection should be done to ensure water safety and prevent the related diseases in these schools.

To study the anti-inflammatory activity of glycyrrhizin acid, ligustrazine and puerarin. In the study, the liquichip-based high-throughput synchronous detection technique for 23 inflammatory factors, uniform design, comprehensive weight method were adopted to study the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin in inhibiting the expression of lipopolysaccharide (LPS)-induced RAW264. 7 cells and multiple inflammatory cytokines. In the study, the uniform design table U₉ (9³) was adopted to design doses of glycyrrhizin acid, ligustrazine and puerarin. The liquichip technique was used to detect the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin on the 23 cytokines expressed in LPS-induced mouse macrophage RAW264. 7 inflammation model. The traditional Chinese medicine component optimization software and the improved least angle regression algorithm were used to analyze the dose-effect relationship among the three components and the cytokine inhibition rate and produce the regression equation. The comprehensive weight method was applied to get the optimal dose ratio of glycyrrhizic acid, ligustrazine and puerarin with highest efficacy of 25:2:13 and verify the optimal dose ratio. The verification results were consistent with the prediction trend, indicating the accuracy of the mathematical model for predicting the experiment. The experimental results showed the multi-target and multi-level efficacies of glycyrrhizic acid, ligustrazine and puerarin and the high anti-inflammatory activity of their combined administration, which provides powerful basis for subsequent drug development.

Glycyrrhizin acid and licorice flavonoids are the component of Glycyrrhiza uralensis Fisch root that has been used for various medicinal purposes in traditional oriental medicine for thousands of years. Macrophages as a principal component of immune system play an important role in the initiation, modulation and final activation of immune response against pathogens. In the present study, glycyrrhizin acid and licorice flavonoids was investigated the anti-inflammatory effect on lipopolysaccharide (LPS)-induced macrophage cell line of RAW264.7. Well-grown RAW264.7 cells were collected and randomly divided into the blank control group, the LPS(1 mg x L(-1)) group, the dexamethasone (5 mg x L(-1)) with LPS group, the glycyrrhizin acid (400, 80, 16 mg x L(-1)) with LPS group and the licorice flavonoids (200, 40, 8 mg x L(-1)) with LPS group. RAW264.7 cells were cultured in 24-well plates, pre-incubated for 4 h with different concentrations of dexamethasone, glycyrrhizin acid, or licorice flavonoids. Then cells were stimulated for 20 h with LPS. The supernatant of culture medium was collected from each well and determinated the concentrations of cytokines by means of BioPlex mouse cytokines assay. Compared with the control group, the LPS group could significantly induced relatively high levels of granulocyte colony stimulating factor (G-CSF), granulocyte-macrophage colony stimulating factor( GM-CSF), macrophage inflammatory protein-1 alpha (MIP-1α), macrophage inflammatory protein-1 beta (MIP-1β), regulated upon activation normal T cell expressed and secreted factor (RANTES), tumor necrosis factor alpha ( TNF-α), monocyte chemotactic protein 1 (MCP-1), chemokine (C-X-C motif) ligand 1 (KC), eotaxin, interleukin(IL)-1α, IL-1β, IL-3, IL-4, IL-5, IL-6, IL-10, IL-12 (p40), IL-12 (p70), IL-13, and IL-17 secretion (P < 0.05). The glycyrrhizin acid significantly inhibited IL-1β, IL-3, IL-5, IL-6, IL-10, IL-12 (p40), IL-12 (p70), IL-13, Eotaxin and TNF-α secreted by LPS-stimulated RAW264.7 cells (P < 0.05). The expression levels of IL-6 and Eotaxin were observably decreased in the licorice flavonoids with LPS group (P < 0.05). The data presented here suggested that the glycyrrhizin acid and licorice flavonoids modulate various cytokines secreted by macrophages and were important anti-inflammatory constituent of Licorice.
