OBJECTIVETo investigate the epidemiological characteristics, clinical manifestations, diagnosis, and treatment of Brucella orchitis, so as to provide reliable evidence for the prevention and treatment of the disease.

METHODSWe conducted retrospective statistical analyses on the medical records of 48 outpatients and 21 inpatients with Brucella orchitis.

RESULTSBrucella orchitis was diagnosed in 6.67% of the male patients with brucellosis (69/1 034). The disease exhibited typical epidemiological features, with a higher incidence rate among those in frequent contact with sheep and elderly people, in the period from April to July, and in the areas with sheep husbandry. All the Brucella orchitis patients had such local symptoms as testicular pain and swelling, more frequently involving both testes, and other most common symptoms included fever, chills, sweating, and painful joints. Based on IIEF-5, 45 of the patients suffered from severe erectile dysfunction, with their reproductive function temporarily affected in the course of the disease. Misdiagnosis easily occurred in the early stage of the disease. Therapeutic options mainly included doxycycline hydrochloride and rifampicin, administered orally or intravenously, which could effect a cure, though relapse might occur in some cases.

CONCLUSIONBru- cella orchitis has distinct epidemiological characteristics, with clinical manifestations of testicular pain and swelling. Though a transient disease, it affects the reproductive function of the patient before cured. It can be treated by combined oral and intravenous medication, with painkillers or ice bags for testicular pain and swelling.

OBJECTIVE:To establish a method for the rapid identification of Sanjiu weitai granule and quantitative analysis of moisture. METHODS:Near-infrared (NIR) spectroscopy was adopted. 38 batches of Sanjiu weitai granule were collected,NIR spectrum was determined by integrating sphere diffuse-reflectance. Conformity test model was performed by comparing consistency index(CI)value and CI limit,and quantitative model of moisture was established using partial least squares(PLS)algorithm. RE-SULTS:When CI value was less than 6,the established model can accurately distinguish Sanjiu weitai granule,the model was proven feasible;the correlation coefficient (r2) of quantitative model was 97.44,the root mean square error of cross validation (RMSECV) was 0.453,the root mean square error of prediction (RMSEP) was 0.748. CONCLUSIONS:The method is simple and rapid without destroying,which can be applied to fast screening of Sanjiu weitai granule in site and fast determination of mois-ture content.

OBJECTIVE:To study the compatible stability of puerarin injection with 10 commonly-used drugs.METHODS:The changes in appearance,pH,particulate and puerarin content after mixing with 10 drugs were observed and assayed.RESU_LTS & CONCLUSION:Puerarin injection mixing with adenosine triphosphate,coenzyme A and ribavirin showed significant change in pH,which indicats that they are incompatable each other,however,when puerarin injection was mixed with vitamin B6,potassium chloride,etamsylate,cimetidine,gentamycin,amikacin and erythromycin,no significant changes in pH,particulate and puerarin content were found,which indicates their compatibility.

ObjectiveTo investigate the expression of caspase-3 in the brain of acutely pentylenetetrazole(PTZ)-kindled rats.MethodsThe caspase-3 positive cells were revealed using immunohistochemical SP method. CMIAS image analysis system was used to analyse the expression of caspase-3 hemi-quantitatively. ResultsFollowing PTZ induced epilepsy, the expression of caspase-3 increased both in the hippocampus and in the cortex, and that was more remarkable in the hippocampus than in the cortex.ConclusionCaspase-3 may be activated during neuronal apoptosis after epilepsy. Hippocampus is more sensitive to the neuronal damage due to epilepsy than the cortex is.

MicroRNA(miRNA) is a class of non-coding RNA that plays an important role in gene expression and controlling. In recent years,the role of miRNA in the development of the disease has aroused great interest. Abnormal osteoclastogenesis and persistent inflammatory response induced by wear particles or osteoblast differentiation and maturation is the main cause of aseptic loosening in joint replacements. New researches shows that persistent inflammatory response, osteoclastogenesis and osteoblast differentiation are closely associated with miRNA, suggesting that there are certain relations between miRNA and aseptic loosening of prostheses. Additionally, the alteration of the expression levels of some miRNA may be curative for aseptic loosening. With the findings of the new miRNA targets, the important role of miRNA is further confirmed.

OBJECTIVEOvertraining is a serious problem in sports, assessed by comprehensive multi-index evaluation, but so far there is still no sensitive, specific monitoring indicator or simple evaluation method to evaluate it. This research established a method for detecting plasma cell free DNA (cfDNA) of rats by real time PCR and discuss edits significance: a new molecular marker of overtraining?

METHODSTwelve male SD rats were randomly divided into control group and overtraining group. The overtraining group rats were undertaken overtraining on a motor-driven treadmill for 5 weeks, while the control group rats kept quiescent. All the rats were drawn blood at pre-and after-5 weeks to detect plasma levels of cfDNA, testosterone (T) and corticosterone (Cort) as well as peroxidation/antioxidation parameters (T-AOC, MDA, SOD, GSH-Px) and creatin kinase (CK).

RESULTS(1) Plasma cfDNA of rat was detected specifically by our real time PCR. (2) Compared with control group rats, the plasma cfDNA of overtraining rats increased obviously (about 5.43 fold). (3) Plasma cfDNA was related to plasma T, Cort, T/C ratio and MDA (correlation coefficent were -0.729, 0.854, -0.655 and 0.720, respectively) rather than plasma T-AOC, GSH-Px, SOD and CK.

CONCLUSION(1) A real time PCR method was established successfully to determine plasma cfDNA of rat. (2) A remarkable raises of plasma levels of cfDNA were found in overtraining rats which were associated with T, Cort and T/C, suggested that plasma cfDNA might be a new molecular marker of overtraining. (3) The increase of plasma cfDNA of overtraining rat might correlate with enhanced oxidative stress induced by overtraining instead of muscle damage.

ObjectiveTo observe the dose of methadone and the compliance of patients to the methadone maintenance treatment(MMT).MethodsWe analyzed the status of 69 patients who were addicted to opiate medication and 44 patients who dropped out in our clinic until July 31,2010.ResultsThere was no significant relationship between patients' urine test and the dose.Crime caused the patients who dropped out.The percentage of positive urine did not decline as the dose increased,but the rate of patients who dropped and the number of positive urine test showed a significant correlation( r =0.523 P =0.000).Crime was the main reason that affected the compliance to MMT and caused dropping out.ConclusionThe use of MMT dose should be individualized.
