Objective To study the epidemic characteristics and disease spectrum of Epstein-Barr virus (EBV) infected children in Zhongshan region, Guangdong province. Methods Clinical data from the children with positive EBV-DNA detected by real-time lfuorescent quantitative PCR between 2011 and 2013 was retrospectively analyzed. Results A total of 409 cases were detected with EBV-DNA positive from 3402 cases, with a total positive rate 12%, and the positive rate is 8.1%in 2011, 10.4% in 2012, 19.5% in 2013, there were significant differences among positive rate (χ2=6804.00, P<0.05). There was no statistically signiifcant difference in the positive rate of EBV-DNA between different gender (χ2=0.239, P>0.05) and different age groups (χ2=136.96, P<0.05). The positive rate of pre-school group is the highest. EBV infection can cause multiple system diseases. The most common disease caused by EBV infection was infectious mononucleosis (61.6%), followed by respiratory tract infection (26.7%), neck lymphadenitis (3.4%), idiopathic thrombocytopenic purpura (2.4%), etc. Among the 409 cases of EBV infection, the concurrent other pathogen speciifc IgM positive cases as MP-IgM positive (n=79), CP-IgM positive (n=47), Parvovirus B19-IgM positive (n=20), HSV-IgM positive (n=11), CMV-IgM positive (n=10), and RV-IgM positive (n=4) were found. Conclusions Infectious mononucleosis is the leading disease in children infected by EBV in Zhongshan region, the annual positive rate is increasing. Multiple pathogen speciifc IgM may be detected positive in children with EBV infection, which should be interpreted in combination with clinical status.

Objective To summarize the clinical characteristics and drug sensitivity of Pseudomonas aeruginosa in children. Methods The data of children with diagnosed Pseudomonas aeruginosa from 2006 to 2016 were retrospectively analysis. Results There were 14 patients who had diagnosis of Pseudomonas aeruginosa, most of whom were infants and toddlers ( 78 . 6%). The common complications were disseminated intravascular coagulation (DIC) and pulmonary hemorrhage. In 14 patients, 7 patients were cured, 4 were died, and 3 were given up treatment by their family because of serious illness. The antimicrobial susceptibility test showed that isolated pseudomonas aeruginosa had good sensitivity to aminoglycosides and quinolones. Conclusion Pseudomonas aeruginosa sepsis is more common in infants and toddlers, with high mortality. For suspected patients, the antibiotic that covers the Pseudomonas aeruginosa should be used in early antibiotic therapy.

OBJECTIVEWith functional magnetic resonance imaging (fMRI), cerebral function imaging of acupuncture and sham acupuncture at Taichong (LR 3) in patients with essential hypertension (EH) was observed to analyze central mechanism of Taichong (LR 3) to treat EH.

METHODSEighteen EH patients were divided into a twisting acupuncture group (10 cases) and a sham acupuncture group (8 cases), which were treated with twisting manipulation and sham acu- puncture at right Taichong (LR 3), respectively. The treatments were both given with 30-second manipulation and 30- second interval for totally 5 min. During the acupuncture, fMRI was adopted to scan the cerebral function imaging of EH patients on resting state, and the acquired data were analyzed with SPM2 module in Matlab software.

RESULTSAcupunc- ture at Taichong (LR 3) in EH patients mainly increased opposite-side oxygen consumption, which generally activated left anterior cingulated gyrus (BA 32), left inferior parietal lobule (BA 40), left inferior temporal gyrus (BA 19), left middle temporal gyrus (BA 37) and right anterior central gyrus (BA 6). The activated areas were related to motor, vision and cognition of emotion. Stimulation region of sham acupuncture mainly included right anterior cingulated gyrus (BA 24), left inferior parietal lobule (BA 40) and left inferior frontal gyrus (BA 7).

CONCLUSIONThe central mechanism of Tai- chong (LR 3) on antihypertensive effect and symptom improvement is not in thalamus and medulla that are traditionally believed to control blood pressure. Taichong (LR 3) could activate anterior cingulated gyrus to regulate parasympathetic nerve and lower blood pressure, and through anterior cingulated gyrus, the connection with the surrounding areas is strengthened to improve the cognitive impairment caused by long-term hypertension.

Objective To discuss the clinical effects of hemiarthroplasty for the treatment of intertrochanteric comminuted fracture in aged patients.Methods From June 2006 to June 2010,91 cases with intertrochanteric comminuted fractures were treated by hemiarthroplasty using Zweymtüller long-stem cementless implant.There were 35 males and 56 females,with an average age of 81.2 years (range,75-94 years).There were fresh fractures in 75 cases and old fractures in 16 cases.According to classification of Evans-Jensen,there were 36 cases with type Ⅲ fracture and 55 with type Ⅳ.Osteoporosis was graded by Singh index,and there were 51 cases with level Ⅲ and 40 with level Ⅱ.The interval between injury and operation was 2-10 d (average,3.5 d).Results The surgery lasted 30-50 min (average,39 min).The blood loss was 320-610 ml (average,405 ml).The hospital stay was 14-21 d (average,16.5 d).Two cases who experienced with the infection of the respiratory system after operation,recovered through routine treatment.Thirty-seven cases were followed up for 15 to 38 months (average,24.5 months).According to the Harris score,the overall rate of excellent or good result was 83.8％ (31/37).Conclusion Hemiarthroplasty using Zweymüller long-stem cementless prosthesis is reliable option for intertrochanteric comminuted fracture in the aged patients.

Objective To establish a rat model of coal-burning-borne fluorosis,and to observe the expression changes of bone morphogenetic protein-2 (BMP-2) and bone morphogenetic protein-3 (BMP-3) in the serum of rat treated with different dose of fluoride and different treatment duration.Methods A total of 120 clean grade SD rats(body mass between 80 to 120 g) weaned for 4 weeks were randomly assigned into four groups,which were control,low-dose fluorid,medium-dose fluorid and high-dose fluorid groups,respectively,and 30 rats in each group (female 15,male 15).All of the rats were fed with coal drying corn from fluorosis area.Ten rats were killed by femoral artery bleeding 30 d,90 d and 180 d after exposed to fluoride,respectively.Serum BMP-2 and BMP-3 level was tested by enzyme-linked immunosorbent assay (ELISA).Results ①Results of BMP-2:after exposed to fluoride for 90 d and 180 d,the differences of serum BMP-2 level between groups were statistically significant(F=385.08,173.98,all P ＜ 0.01).In low-dose fluorid,medium-dose fluorid and high-dose fluorid groups,the expression of serum BMP-2 at 90 d[(18.80 ± 0.43),(22.22 ± 0.85),(25.14 ± 0.69)μg/L] and 180 d[(7.98 ± 0.68),(8.97 ± 0.78),(15.04 ± 0.89)μg/L] was higher than that of control group[(12.54 ± 1.29),(7.53 ± 0.97)μg/L,all P ＜ 0.05],and the level of BMP-2 increased with increasing dose of fluoride (all P ＜ 0.05).Within each group,the difference of serum BMP-2 was statistically significant(F =55.42,511.58,686.35,671.64,all P ＜ 0.01).The expression of BMP-2 in each group at 90 d [(12.54 ± 1.29),(18.80 ± 0.43),(22.22 ± 0.85),(25.14 ± 0.69)μg/L] was higher than that at 30 d[(11.75 ± 1.15),(11.42 ± 1.07),(11.38 ± 0.92),(11.15 ±1.03)μg/L,all P ＜ 0.05].The expression of BMP-2 in each group at 180 d[(7.53 ± 0.97),(7.98 ± 0.68),(8.97 ± 0.78),(15.04 ± 0.89) μg/L] was lower than that at 90 d.②Results of BMP-3:the difference between groups was not statistically significant at every experimental stage(F =0.7215,1.2951,0.0964,all P ＞ 0.05).Conclusions Longer excessive fluoride intake stimulates the expression of BMP-2 in rats,but with prolonged fluoride intake,the stimulation becomes weak.The effect of fluoride on BMP-3 is not as sensitive as that on BMP-2.

Objective To evaluate the biocompatibility of vessel extracellular matrix (VECM) with bladder smooth muscle cells of rabbits,and to discuss the feasibility of vessel extracellular matrix as a matrix for urinary tract reconstruction.Methods Primary cuhured bladder smooth muscle cells (RBSMCs) iso- lated from New Zealand rabbits were implanted on VECM (1?10~6 cells/ml).The effect of VECM on meta- bolic activity,attachment,proliferation of RBSMCs were monitored in vitro by inverted light microscopy and scanning electron microscopy.The extracts of VECM and emulsion were prepared as experimental group and positive controls separately.The culture medium was used as negative control,and simple culture medium without cells was used as blank control.The cell viability was monitored by MTT method after 1-,3-,5-d see- ding.The in vivo tissue response to VECM was investigated by implanting into the subcutaneous sites of the rabbits.Results VECM exhibited nontoxic and bioactive effect on RBSMCs.RBSMCs could be attached to and proliferated on VECM and remained their morphologies.The cell proliferation rates of experimental group were 95.61%、98.34%、102.91%,respectively,after 1,3,5 d;those of negative control group were 100.00% ,respectively;and those of positive control group were 35.14%、38.95%、32.66%,respectively. There was significant difference in the rate between experimental group and positive control (P＜0.01),and no significant difference in the rate between experimental group and negative control (P＞0.05).In vivo, VECM demonstrated favorable tissue compatibility without tissue necrosis and fibrosis.Conclusions VECM exhibits nontoxic and bioactive effects on primary cultured bladder smooth muscle cells.It is a suit- able material for urinary tract reconstruction.
