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.

The pathogenesis of multiple sclerosis ( MS) involves alterations to multiple pathways and processes, which represent a significant challenge for developing more-effective therapies.In MS, abnormalities have been identified in several cytokine-signaling pathways, as well as those of other immune receptors.Among the downstream molecules implicated are Jak/Stat, NF-κb, ERK1/2, p38 or Jun/Fos, current MS drugs target some of these pathways.This article will with the aid of the latest research results of systems biology approaches that study pathway dysregulation in the process of MS development, targeting these relevant MS-signaling pathways, offers the opportunity to accelerate the development of novel individual or combination therapies for the future of new drug research.

Objective To compare the efficiency of oscillation with sonication in preparing nano-scale microbubbles (NBs).Methods Nano-scale microbubbles were prepared using oscillation and sonication respectively,and then compared the NBs' size,size distribution,concentrations and time-consumption of the two methods.Results The sizes of nanobubbles prepared by sonication and oscillation were (373.88 ±18.43)nm and (360.74 ± 14.39)nm,respectively.There was no significant difference in size between the two methods (P =0.523).The polidispersity was larger in sonication before centrifugation,there was significant difference between the two methods (P ＜0.001).The concentration of nanobubbles prepared by oscillation was (1.48 ± 0.15) × 1010,which was higher than that by oscillation [(8.07 ± 0.62) × 108],there was significant difference between the two methods (P ＜ 0.001).The consuming time was shorter in oscillation,the difference was significant when compared with sonication (P ＜0.001).Conclusions Both two methods can successfully prepare NBs.Compared with sonication,oscillation can effectively produce NBs with smaller polidispersity,higher concentration and shorter time-consumption.

Objectives To explore the perceived stigma among family members of people with schizophrenia and to identify the influential factors related to perceived stigma in socio-demographic characters of family members and patient characters.Methods Total 127 family members of people with schizophrenia in a psychiatric hospital in Beijing were surveyed by the Perceived Devaluation-Discrimination Scale developed by Link.Results The mean score of the perceived devaluation-discrimination scale is 2.60±0.44.It was significantly higher than the 2.5 midpoint(t=2.53,P<0.05).Family member's perceived stigma was significantly different between different groups of residence area,education level,occupation and family income (P<0.05).Perceived stigma were not affected by patient characters (P>0.05).Family members'education level was the influencing factors of stigma,and the R~2 Square is 0.213.Conclusions The family members of people with schizophrenia suffered from high stigma.Education level of family member may be one of the influential factors.

ObjectiveTo investigate the clinical phenotypes of familial hypercholesterolemia (FH) caused by exon 13 A606T mutation in low deusity lipoprotein receptor.MethodsClinical data of the suffered family were collected and analyzed,as well as measurement of perivascular intima-medial thickness and follow-mediated-dilation function by ultrasonography.ResultsThere were totally 11 sufferers including 4 males and 9 females,aged 8-90 years,with 2 homozygotes and 9 heterozygotes.Among them, one homozygote showed angina pectoris and hematuria,both homozygotes had skin xanthomata.TC,TG,LDL-C and HDL-C were(7.39 ± 1.30) mmol/L,(0.93 ± 0.36) mmol/L,( 11.76 ± 1.10) mmol/L and ( 1.22 ±0.17) mmol/L,respectively.The left/right sided intima-medial thickness of the common,internal,external and bulb carotid artery were ( 1.15 ±0.45) mm/( 1.30 ±0.60) mm,(0.82 ±0.30) mm/( 1.00 -0.66)mm,(0.77 ±0.28) mm/(0.78 ±0.30) mm and ( 1.40 ±0.59) mm/( 1.46 ±0.71 ) mm respectively.The brachial artery flow mediated dilation rate was (4.85 ±4.80)％.Echocardiography revealed 2 patients with cardiac valvular disease and 3 with atrium septum aneurysm. ConclusionFH patients show a variety of phenotypes incuding extraordinary hypercholesterolemia,subcutaneous xanthomata and premature coronary heart disease.

Background5-Nitro-2-(3-styrene-acrylic amine) benzoic acid ( NPPB),a chloride channel inhibitor,has a promoting effect on cell apoptosis in myocardial ischemia and reperfusion of domestic rabbit.The CIC chloride channel has been found in the ocular trabecular cells.However,the effect of NPPB on the shape and function of trabecular cells is unclear. Objective This study was performed to investigate the effect of NPPB on the proliferation,cell cycle progression and apoptosis of human trabecular meshwork cells.MethodsThe immortalized human trabcular cell strain was cultured,and logarithmic-phase cells were incubated in 96-well plates at a density of 1 ×106/ml.Different concentrations of NPPB (10,50,100 μ mol/L) were added to the medium,and the MTT assay was used to assess the growth and proliferation of the cells.Flow cytometry was used to evaluate the cell cycle.Then,100 mg/L 5-FU or 100 mg/L 5-FU + 100 μmol/L NPPB was used to induce cell apoptosis,which was assessed by Annexin V-PI.The membrane potential of mitochondria was examined using rhodamine 123 (△ψm).Results After 48 hours of treatment with NPPB,the abosorbency (A value) of the cells was gradually lowered with the increasing dose of NPPB,with significant differences among the 4 groups (F =7.230,P =0.006).Compared with the 10 μmol/L NPPB group,the A values were significantly declined in the 50 and 100 μmol/L NPPB groups (t =1.610,P =0.025 ;t =12.270,P =0.001 ).Forty-eight hours after exposure to NPPB,the percentage of cells in G0/G1 phase was increased and that in the S phase was decreased.The percentages of cells in different phases of cell cycle were significantly different in comparison with their control groups (without NPPB)( P＜0.05 ).Twenty-four and 48 hours after the treatment with 100 mg/L 5-FU,the apoptosis rates of the cells were raised in the 100 mg/L 5-FU group and 100 mg/L 5-FU + 100 μmol/L NPPB group compared to the without NPPB group (t24h =2.130,P =0.023;t48h =4.810,P=0.011 ) ;while that in the 100 mg/L 5-FU+100 μmol/L NPPB group was higher than the 100 mg/L 5-FU group ( t24 h =1.980,P =0.037 ; t48 h =1.290,P =0.028 ),and the mitochondrial membrane potential was lowered ( t24h =1.580,P =0.029 ; F48 h =6.200,P =0.015 ).Conclusions NPPB suppresses the proliferation of human trabecular cells and promotes the cells to enter S phase via the G1/S check point.In addition,ClC might be involved in an anti-apoptosis mechanism through the internal mitochondrial pathway.

Objective Increased renal mast cells have been found in significant correlation with clinicopathological features of diabetic nephropathy ( DN) .However, the exact pathological significance of mast cells still remained to be elucidated.As one of the most abundant serine proteases, tryptase is specifically expressed by mast cells.The study was to observe the expression of tryptase in the urine of patients with diabetic nephropathy and realize the pathological significance of urinary tryptase and renal mast cells in the development of diabetic nephropathy. Methods Urine samples from 103 patients with diabetic nephropathy who were hospitalized at the clinical unit of the nephrology centre of Jingling Hospital from January 2012 to June 2013 were collected.According to concentra-tion of urinary albumin excretion rate, the patients were conducted to early-stage DN group (microalbuminuria,n=10), middle-stage DN group (proteinuria stage, n=31) and end-stage DN group (renal insufficiency stage,n=62).Meanwhile, urine samples from 20 normal persons were taken as the normal control group.Tryptase level in each urine sample was measured by using an ELISA kit.The average tryptase levels were compared among different groups and the correlation between urinary tryptase level and clinical indices was analyzed. Results ①In most cases, tryptase was not detected in the urine samples from normal persons(0.7 ±1.4 ng/mg creati-nine).However, the urinary trypatse level increased significantly with the development of diabetic nephropathy (11.6 ±10.5 ng/mg creatinine for early stage, 29.7 ±19.2 ng/mg creatinine for middle stage, and 44.6 ±43.4 ng/mg creatinine for late stage group).②The urinary tryptase level was found in significant correlation with ser-um creatinine (r=0.325, P<0.01), serum cystatin C (r=0.391, P<0.01), serum urea nitrogen (r=0.27, P<0.01), 24 hour uri-nary protein (r=0.389, P<0.01), urine C3 (r=0.276, P<0.05), urine retinol-binding protein (r=0.365, P<0.01), urine lysozyme (r=0.461, P<0.01), urine N-acetyl-β-glucosaminidase level (r=0.568, P<0.01), urinary kidney injury molecule-1 (r=0.434, P<0.05) and interleukin-18 level (r=0.375, P<0.05).No significant correlation was found between urinary tryptase level and age, gender, fasting blood sugar, postprandial blood sugar, HbA1c, triglyceride, high density lipoprotein or low density lipo-protein. Conclusion Mast cells play an important role in the development of diabetic nephropathy and might be a novel and effective target for the treatment of DN.

Objective To discuss clinical significance on early diagnosis of brain injury in premature infants with multiple sequence joint inspection of magnetic resonance imaging (MRI).Methods The brain MRI findings of 160 premature infants treated by Neonatal Intensive Care Unit were analyzed retrospectively.Results In 160 premature infants,brain injury occurred in 76 cases,the incidence of brain injury was 47.5％.Ischemic lesions were seen more in brain injury in premature infants,cerebral white matter injury was the most common,especially periventricular leukomalacia.Ischemic brain injury performed patchy or large sheet increased signal intensity on T1-weighted images(T1 WI),decreased signal intensity on T2-weighted images (T2WI) and obviously increased signal intensity on diffusion weighted imaging (DWI) in half egg circle center and around the lateral ventricle.Periventricular leukomalacia performed patchy decreased signal intensity on T1WI,increased signal intensity on T2WI and decreased signal intensity on DWI.Periventricular-intraventricular hemorrhage was seen more in hemorrhagic lesions.Hemorrhage stove was performed different signal because of different bleeding time.MRI performance in acute phase was iso-signal or slightly decreased signal intensity on T1WI,increased signal intensity on T2WI,increased signal intensity on T1WI,slightly decreased signal intensity on T2WI in early subacute,increased signal intensity on T1 WI and T2WI in late subacute and obviously decreased signal intensity on magnetic sensitive weighted imaging.The detection rate of ischemic lesions by DWI was higher than the conventional MRI,and DWI could show cerebral white matter damage of premature infants much earlier than the conventional MRI.The detection rate of hemorrhage stove by susceptibility weighted imagingc (SWI) was higher than the conventional MRI (x2 =23.78,P ＜ 0.05),and SWI could show hemorrhagic lesions much earlier than conventional MRI (x2 =27.02,P ＜ 0.05).Conclusions MRI,especially combined multiple sequence checking,could provide accurate imaging evidence for the early diagnosis of brain injury in premature infants.

0.05), and both groups got ideal clinical effect. Conclusions MGHSV is an ideal operation for various types of duodenal ulcer, which with a preferable long-term effect. It is worth to be widely applied in clinical practice.

Objective To compare the short-term efficacies of laparoscopic adjustable gastric banding (LAGB) and laparoscopic sleeve gastrectomy (LSG) in the treatment of obesity and type 2 diabetes mellitus,and to investigate the relationship between the body weight loss and the decrease of glucose of the 2 treatment methods.Methods The clinical data of 40 patients with obesity combined with type 2 diabetes mellitus who were admitted to the Changhai Hospital of the Second Military Medical University from January 2010 to December 2011 were retrospectively analyzed.There were 14 patients treated by LAGB (LAGB group) and 26 by LSG (LSG group).The body weight loss and the decrease of glucose at postoperative year 1 of the 2 groups were compared.The differences in the body weight and glucose before and after operation within groups were compared using the paired t test,and the differences in the body weight and glucose between the 2 groups were compared using the multiple analysis of variance.The correlation between the body weight loss and the decrease of glucose was analyzed using the linear regression analysis.Results Laparoscopic surgery was successfully done without conversion to open surgery or intraoperative complications.The operation time and volume of blood loss were (69 ± 16)minutes and (31 ± 14)mL in the LAGB group,(120 ± 15) minutes and (148 ± 48) mL in the LSG group.Complications including postoperative malnutrition,electrolyte disturbance,delayed gastric emptying,bleeding,anastomotic leakage did not occurr in the 2 groups.Two patients were complicated with abdominal incision fat liquefaction,and were cured by symptomatic treatment.(1) The body weight,body mass index (BMI) and waistline had a decrease trend.The body weight,BMI and waistline in the LAGB group were decreased from (117 ± 28)kg,(40 ± 8)kg/m2 and (118 ± 15) cm before operation to (94 ± 28) kg,(33 ± 8) kg/m2 and (92 ± 15) cm at postoperative week 48.The body weight,BMI and waistline in the LSG group were decreased from (119 ± 25)kg,(42 ± 6)kg/m2 and (123 ± 14)cm before operation to (74± 16)kg,(26± 4)kg/m2 and (86 ± 13)cm at postoperative week 48.The EWL had an increase trend in the 2 groups.The EWL in the LAGB group was increased from 7％ ± 2％ at postoperative week 1 to 53％± 24％ at postoperative week 48,and the EWL in the LSG group was increased from 11％ ± 4％ at postoperative week 1 to 90％ ± 20％ at postoperative week 48.There were significant differences in the changes of body weight,BMI,waistline and EWL between the 2 groups (F =60.660,74.490,57.650,90.020,P ＜ 0.05).(2) The levels of glycosylated hemoglobin,fasting glucose,fasting insulin,HOMA-IR,triglyceride,total cholesterol,low-density lipoprotein and high density lipoprotein in the LAGB group were decreased from 8.1％± 0.8％,(8.4±0.6)mmol/L,(21±8)μmol/L,7.9 ±2.9,(1.68±0.50)mmol/L,(6.0±1.1)mmol/L (4.1 ± 0.8) mmol/L,(1.09 ±0.15)mmol/L to 6.4％ ±0.8％,(6.3 ±0.3) mmol/L,(10 ± 3) μmol/L,2.7 ±0.9,(1.04 ± 0.09) mmol/L,(4.3 ± 0.8) mmol/L,(2.3 ± 0.4) mmol/L,(1.22 ± 0.09) mmol/L at postoperative week 48 ; the levels of glycosylated hemoglobin,fasting glucose,fasting insulin,HOMA-IR,triglyceride,total cholesterol,low-density lipoprotein and high density lipoprotein in the LSG group were changed from 7.9％ ± 1.0％,(9.0±1.0)mmol/L,(21 ±9) μ mol/L,8.5 ±3.5,(2.09 ± 0.70) mmol/L,(6.0 ± 1.2)mmol/L,(3.9 ± 1.1) mmol/L,(1.06 ± 0.21) mmol/L before operation to 5.1％ ± 0.8％,(5.2 ± 0.4) mmol/L,(4 ± 1)μmol/L,0.9±0.2,(1.22±0.17)mmol/L,(4.2±0.8)mmol/L,(2.3 ±0.6)mmol/L,(1.30±0.13)mmol/L at postoperative week 48.There was a decrease trend of the glycosylated hemoglobin,fasting glucose,fasting insulin,HOMA-IR,trigluceride,total cholesterol and low density lipoprotein and a increase trend of the high density lipoprotein in the 2 groups.There were significant differences in the levels of glycosylated hemoglobin,fasting glucose,fasting insulin,HOMA-IR,triglyceride,total cholesterol,low-density lipoprotein and high density lipoprotein between the 2 groups (F =57.650,74.270,36.750,42.960,10.870,30.650,32.560,11.490,P ＜0.05).The levels of glucose of the LAGB group at postoperative month 1 and 3 were influenced by BMI (b =0.543,0.753,P ＜ 0.05),while the levels of glucose of the LAGB group did not be influenced by BMI at postoperative month 6 and year 1 (b =0.130,0.222,P ＞0.05).The levels of glucose of the LSG group did not be influenced by BMI at postoperative month 1,3,6 and year 1 (b =0.185,0.035,0.212,0.126,P ＞0.05).Conclusions The efficacy of LSG is superior to LAGB for the treatment of obesity combined with type 2 diabetes mellitus.The efficacy of LAGB is correlated with the change of body weight,while the efficacy of LSG does not correlated with the change of body weight.
