Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common disease in males, which is characterized by persistent discomfort or pain in the pelvic region. As currently used drug therapies fail to produce satisfactory results, it is an urgent task to find new and effective methods for the treatment of CP/CPPS. In recent years, many reports are seen on the extracorporeal shock wave therapy (ESWT) for CP/CPPS. ESWT can significantly improve the symptoms of pelvic pain and urination disorders in CPPS patients, and its therapeutic effect is attributed to the improvement of angiogenesis and block of pain nerves.

OBJECTIVETo comparatively study the effects of Rhubarbs from different regions on blood lipid and antioxi dation of hyperlipidemia rats.

METHODSMale rats were randomly divided into 9 groups ( n = 8) and fed with high-fat diet to replicate the hyperlipidemia model. Meanwhile, Rheum tanguticum was administrated intragastrically at two doses (3.0 g/kg and 1.0 g/kg), once a day for continuous 28 days. The effects of Rheum tanguticum planted in Gannan (RT-GN), Rheum tanguticum planted in Xinin (RT-XN) and Rheum plmatum planted in Lixian (RP-LX) were evaluated through detecting the parameters of blood lipids, blood viscosity and antioxidant system.

RESULTST-GN, RT-XN and RP-LX in the range of 1.0-3.0 g/kg could decrease the blood levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and malonaldehyde (MDA) in blood. Besides, they could reduce blood viscosity, increase high density lipoprotein (HDL) level and upregulate the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Interestingly, their effects on blood viscosity was obviously in a dose dependent manner. In addition, the effects of RT-GN on LDL, MDA and blood viscosity were not significantly different from those of RT-XN and better than those of RP-LX.

CONCLUSIONThe RT has better hypolipidemic effects than the RP, but RT-GN and RT-XN are not different from the above effects.

The biochemical mechanism of degrading keratins by S.fradiae var S-221 was primarily studied.The compounds (Na_ 2 SO_ 4 , Na_ 2 SO_ 3 and sulfdryl acohol), which respecitively enhance specific activity of keratinase, activate keratinase intensively and mainly act on the disulfide bonds reductase in the keratinase, Na_ 2 SO_ 3 activates intensively both disulfide bonds reductase and polypeptide hydrolytase at 0.01 mol/L, whereas Na_ 2 S_ 2 O_ 3 , which acts on the disulfide bonds reductase, inhibits keratinase.On the condition that substrate, keratins exists, S.fradiae var S-221 is induced to produce exo-keratinase, which is a multiproteinase, containing disulfide bonds reductase, which is a key enzyme degrading keratins, then, with polypeptidic, hydrolytase, graduately hydrolyzates denatured keratins into polypeptides, oligopeptides and free amino acids, so that keratins have been decomposed completely.Sulfur in the keratins was transferred into sulfhydryl compounds, H_ 2 S and sulfates in the course of keratinolysine.

Nowadays, nanotechnologies have shown wide application foreground in the biomedical field of medicine laboratory tests, drug delivery, gene therapy and bioremediation. However, in recent years, nanomaterials have been labeled poisonous, because of the disputes and misunderstandings of mainstream views on their safety. Besides, for the barriers of technical issues in preparation like: (1) low efficacy (poor PK & PD and low drug loading), (2) high cost (irreproducibility and difficulty in scale up), little of that research has been successfully translated into commercial products. Currently, along with the new theory of "physical damage is the origin of nanotoxicity", biodegradability and biocompatibility of nanomaterials are listed as the basic principle of safe application of nanomaterials. Combining scientific design based on molecular level with precision control of process engineering will provide a new strategy to overcome the core technical challenges. New turning point of translational medicine in nanotechnology may emerge.

To determine the optimum conditions of supercritical CO2 extraction of Xiaoyaosan, and establish its fingerprint by gas chromatography-mass spectrometry (GC-MS), the yield of extract were investigated, an orthogonal test was used to quantify the effects of extraction temperature, pressure, CO2 flow rate and time, and fingerprint analysis of different batches of extracts were by GC-MS. The optimal extraction conditions were determined as follows: extraction pressure 20 MPa, extraction temperature 50 degrees C, CO2 flow rate 25 kg x h(-1), extraction time 3 h, and average yield 2.2%. The GC-MS fingerprint was established and 27 common peaks were found, whose contents add up to 81.89% of the total peak area. Among them, 21 compounds were identified, accounting for 53.20% of the total extract. The extraction process is reasonable and favorable for industrial production. The GC-MS method is accurate, reliable, reproducible, and can be used for quality control of supercritical CO2 extract from Xiaoyaosan.

Acute pancreatitis (AP) is an inflammatory disease of the pancreas. Its pathogenesis is not only related to abnormal activation of trypsinogen, but also related to calcium overload, mitochondrial dysfunction, impaired autophagy and endoplasmic reticulum stress. However, the mechanism has not been fully elucidated and needs to be further studied. Currently, there is no effective treatment for AP. It is difficult to prevent the loss of pancreatic function. An in-depth understanding of the pathophysiological mechanisms of AP may help to identify the potential therapeutic targets. Therefore, the purpose of this study is to review recent advances in the mechanism of AP in order to provide more research direction for treatment.
