Objective: To investigate the changes of maximum urethral pressure (MUP) and maximum urethral closure pressure (MUCP) after artificial urethral sphincter (AUS) implantation and their prognostic value. Methods: The clinical data of patients who had undergone AUS implantation in multiple medical centers between March and July 2019 were retrospectively analyzed. Data of urethral pressure profilometry, pad usage, related scores and complications related to surgery were collected and compared. The primary endpoint was social continence (defined as 0-1 pad/d) 1 month after activation of the pump. Results: A total of five male patients were included in this study. Two underwent transurethral resection of the prostate for benign prostatic hyperplasia, two underwent radical prostatectomy for prostate cancer, and one underwent urethral reunion, urethral stricture dilatation and cystostomy due to trauma from traffic accident. All patients had different degrees of urinary incontinence. The results of preoperative urethral profilometry test showed that the MUP of five patients were 52, 53, 88, 32, and 66 cmH(2)O(1 cmH(2)O=0.098 kPa), respectively, and the MUCP were 17, 52, 62, 27, and 40 cmH(2)O, respectively. AUS implantation was performed. The intraoperative urethral pressure profilometry showed that the MUP were 53, 113, 50, 77, and 89 cmH(2)O in the inactivated state, and the MUCP were 50, 97, 31, 71, and 51 cmH(2)O, respectively. In the activated state, the MUP were 112, 174, 193, 121, and 120 cmH(2)O, and the MUCP were 109, 160, 175, 114, and 92 cmH(2)O, respectively. All patients met the social continence (0-1 pad/d) criterion. No complications were reported during the follow-up. Conclusions: The relationship between the range of intraoperative urethral pressure and the effect of urinary control can be gained by measuring the specific values of MUP and MUCP during AUS implantation and the post-operative effects, which provides as a data basis for standardizing AUS implantation.

Solidago canadensis, a clonal herb originally from North America (common name: Canada goldenrod), is an invasive species in many countries. We developed microsatellite primers for this species. Eleven polymorphic loci were generated and primers were designed. Polymorphism of these 11 loci was assessed in 35 plants from two populations (Wuhan and Shanghai) in China. The number of alleles per locus ranged from 3 to 14. The observed and expected heterozygosities varied from 0.0732 to 0.7391 and from 0.1177 to 0.8687, respectively. These microsatellite markers will be useful tools for studies of population genetics in the native and invasive range of this species.

AIMS/HYPOTHESIS: Increasing evidence suggests that diabetes is associated with an enhanced risk of cognitive decline. The precise mechanisms underlying diabetes-associated cognitive decline (DACD) remain unclear. Here we investigated the molecular changes associated with DACD using a comparative proteomics study of hippocampus in a rat model of type 2 diabetes. In addition, we tested the effects of the Chinese medicine ZiBu PiYin recipe (ZBPYR) on DACD. METHODS: The hippocampus was dissected from control, diabetic and diabetic rats treated with ZBPYR (DM/ZBPYR). Soluble proteins were separated using fluorescence-based difference gel electrophoresis. Protein spots were visualised with fluorescent dyes and spot density was compared between each pair of groups. Proteins of interest were identified using mass spectrometry. Proteins of specific interest were also tested by western blot and real-time PCR analysis. RESULTS: We found 13 spots that were altered between control and diabetes groups, and 12 spots that were changed between diabetes and DM/ZBPYR groups. The identities of nine proteins were determined by mass spectrometry. The identified proteins were largely involved in energy metabolism, cytoskeleton regulation and oxidative stress. The protein alterations observed in the diabetes group were ameliorated to varying degrees following ZBPYR treatment. CONCLUSIONS/INTERPRETATION: The protein changes identified in hippocampus from a rat model of type 2 diabetes suggest that specific cellular alterations contribute to DACD. The Chinese medicine ZBPYR was found to affect multiple targets and partially repaired the original cellular balance. This study may provide important insights into the molecular events underlying DACD and allow the identification of novel therapeutic targets.

OBJECTIVE: To evaluate the effect of Zhuyu Tongfu mixture (ZYTFM) in curing enterogenus infection. METHODS: Experimental model of enterogenous infection in mice caused by endotoxin was used. The positive translocation trate (PTR) and mumber of viable bacteria in viscera and serum level of superoxide dismutase (SOD) were measured before and after ZYTFM treatment. RESULTS: The PTR and number of viable bacteria in liver, spleen and mesocolon in the ZYTFM group were much lower than those in the model group and the placebo group (P < 0.01). Whereas the SOD level of the ZYTFM group was significantly higher than that in the latter two groups (P < 0.05-0.01). Pathological examination displayed that ZYTFM could markedly alleviate the mucosal damage of small intestine. CONCLUSION: ZYTFM has an obvious curative effect on enterogenous infections induced by endotoxin.

The seeds and leaves of Ziziphus Spinosa exert a similar inhibiting effect on central nervous system function, while the fruits have a synergism with pentobarbitol sodium and thiopental sodium on prolongation of sleep and sedation, also decreases coordinated action. Jujuboside A exerts no inhibiting effect, but a synergism with phenylalanine on central nervous system function.

Rabbit model of fever was produced by means of subcutaneous inoculation of pneumocci. Third ventricular intubation and irrigation were carried out in rabbits. Irrigation fluid was collected during the stage of normal temperature, at the peak of fever and when the temperature was lowered by rhubarb. cAMP was detected with RlA in each of the three portions of the irrigated CSF. The result showed that cAMP level was raised during fever and decreased after rhubarb administration. Irrigation of CSF without medication had no significant influence on cAMP level.

The effects of rhubarb on arachidonic acid metabolism in renal medulla of rabbits were studied in vitro with radiochromatography and radioautography. The results showed that radioactive agent was markedly reduced in the rhubarb group and significant difference vs the control was observed (P less than 0.01). The results indicated that rhubarb blocked the biosynthesis of renal medulla PGE2 and PGF2 alpha in a dose-dependent manner. Also the rhubarb inhibited the biosynthesis of PGA2 and TXB2. It was suggested that the site of action of the rhubarb is at cyclooxygenase level.
