4.Brucella orchitis: A retrospective study of 69 cases.
National Journal of Andrology 2016;22(1):46-51
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 Stem cell therapy has been extensively used in clinical practice. However ,the methods available are unable to non‐invasively detect the distribution of cells in vivo. This study was aimed to establish a novel molecular imaging probe for stem cell labeling ,which would monitor cells via fluorescence imaging. Methods 1‐iodododecane was used to modify polyethyleneimine (PEI) to form amphiphilic macromolecules. These macromolecules encapsulated the hydrophobic quantum dots by self‐assembly to form imaging probes. Results Strong fluorescence signals of the probe occurred at 630 nm ,and the probe could be effectively endocyted by mesenchyme stem cells. In vivo imaging showed that significant optic signals occurred in probe‐labeled mesenchyme stem cells compared with the control cells (blank group:1.47e8 [p/s/cm2/sr]/[μW/cm2 ];test group:2.78e8 [p/s/cm2/sr]/[μW/cm2 ]). Conclusion The nanoprobes have good optic imaging effects ,and can be used to la‐bel cells.

Objective To explore the usage of anatomic al M-mode echocardiography in observing pulmonary artery motion curve of pulmonary hypertension patients.Methods The subjects included 21 pulmonary hypertension patients complicated with tricuspid valve insufficiency, and 21 controls whose age and gender matched with the patient group. The inner diameter of main pulmonary artery and right atrium, acceleration time of pulmonary valve Doppler signal and maximum velocity of tricuspid insufficiency (ACTpv) were measured during routine echo examination. From the maximum velocity of tricuspid insufficiency the pulmonary artery systolic pressure (PASP) was calculated. The pulmonary artery motion curve and pulsating amplitude of pulmonary artery wall (PAWPA) was observed and measured with a home-made anatomical M-mode echocardiography with instrument. Results PAWPA in the patient group was lower, and simultaneously complicated with broader pulmonary artery, larger right atrium and shorter ACTpv in comparison with normal group (all P

Objective To explore the operational indications, preoperative evaluation,operative essentials and clinical prospect of endovascular repair(EVR) for aortic dissection.Methods Twenty-six patients underwent EVR for aortic dissection and all cases were Stanford B dissection.Four patients had two or more tear entries in different sites.Computed tomography angiography(CTA) or digital subtraction angiography(DSA) were used as preoperative evaluation methods.Results The grafts were installed successfully in 26 patients(100%).The patients were followed up for 1 to 18 months after treatment,and there was no endoleaks and organ or limb ischemia in all the patients.Conclusion Endovascular repair was simple,safe and effective in treating aortic dissection and dissecting aneurysm.
