PURPOSE: In the diagnosis of pediatric urinary tract infection(UTI), the use of invasive methods, such as voiding cystourethrography(VCUG), is controversial. A retrospective study was carried out to evaluate the necessity for VCUG in assessing pediatric UTI. MATERIALS AND METHODS: Between April 2000 and March 2002, 70 children (60 boys, 10 girls) with symptomatic UTI were evaluated. All patients were evaluated with renal ultrasonography(RUS), 99mTc-DMSA renal scintigraphy(DMSA renal scan) and VCUG. The results of the VCUG were compared with RUS and similar comparisons made between the results of the VCUG and DMSA renal scans. Patients with both normal a RUS and DMSA renal scan were then evaluated for the frequency and grade of vesicoureteral reflux(VUR) on the VCUG. RESULTS: The mean age at the initial evaluation was 7.95 months, ranging from 1 to 52 months. RUS and DMSA scan abnormalities were found in 38(54.3%) and 26(37.1%) children, respectively. Of the 22 patients with VUR confirmed by VCUG, 11(50.0%) had an abnormal RUS, and 12 (54.5%) patients had abnormal DMSA renal scans. Of the 19 patients with both a normal RUS and DMSA scan, 4(21.2%, 6 kidney-ureter unit) were found to have VUR on VCUG. CONCLUSIONS: This study illustrated that a considerable number of patients may have significant VUR, despite normal renal ultrasonography and DMSA scans. Therefore, VCUG remains important in assessing pediatric UTI.

During past 50 years,has achieved a great progress and derived some profound lessons worthy of learning and studying for our country.This article introduces the deinstitutionalization processes of mental health institutions,reinstitutionalization and the inspiration for Chinese mental health reform.Introduced the paper are the reform of deinstitutionalization of mental health institutions in USA and some other countries,and the concept of such a reform,pointing out inspirations of such a reform for mental health reform in China.

Objective To explore the clinical features, surgical techniques and treatment efficacy of blood blis?ter-like aneurysms (BBA) of the internal carotid artery (ICA). Method We retrospectively reviewed 45 BBAs of the ICA treated surgically at our department between Jan. 2006 and Jan. 2016. The data was analyzed. Results Direct clipping of BBA was performed in 38 patients, clipping over wrapping in 3 patients and trapping of ICA in 4 patients. Intraoperative rupture occurred in 12 patients (27%). Postoperative cerebral infarction developed in 10 cases (22%). Seven patients died (16%). During the follow-up time of 47 months (range, 6~126 months), Good results were achieved in 34 patients (76%) with a modified Rankin Scale (mRS) 0~2 and 4 patients were in mRS 3~5. Follow-up angiography revealed a re?currence of BBA in one patient, which was retreated with endovascular coiling. No rebleeding was found in all fol?lowed-up patients. Conclusions BBAs of the ICA are difficult to treat surgically with high risk and complications. Thoughtful pre-operative evaluation of BBA and application of various surgical strategies during operation can signifi?cantly reduce the surgical risk and achieve good outcomes.

Under the influence of Chinese medicine scientization, Chengjiang Acupuncture School, which was originated in the Republic of China (1912 - 1949), has also undergone a series of scientific practice. The Chengjiang School established scientific research, education and medical organizations such as the Research Society of China Acupuncture-Moxibustion, China Acupuncture-Moxibustion School, Training School of China Acupuncture-Moxibustion and Sanatorium of Acupuncture-Moxibustion. Zhenjiu Zazhi (Journal of Acupuncture-Moxibustion) was established, and monographs and textbooks such as Zhongguo Zhenjiu Zhiliaoxue (Therapeutics of Chinese Acupuncture-Moxibustion) and Zhongguo Zhenjiuxue Jiangyi (Lectures on Chinese Acupuncture-Moxibustion) were published. Meanwhile, based on clinical practice, large members of acupuncture personnel with scientific literacy emerged. Therefore, it is held that the scientization of Chengjiang School has performed a profound influence on the development of modern acupuncture-moxibustion.

Objective To construct multiple myeloma mucin MUC1-2VNTR gene eukaryotic expressing vector,which provided the basic material for further study of multiple myeloma DNA vaccine.Methods MUC1-2VNTR coding gene as target gene,and a KOZAK sequence was inserted before it.Hind Ⅲ and Xba Ⅰ restriction enzyme site were inserted on both ends.Then the whole sequence was synthesized and cloned into pcDNA3.1/myc-his B vector,and the recombinant vector was identified by restriction enzyme digestion and DNA sequencing.Results Synthesized MUC1-2VNTR gene was 140 bp.Restriction enzyme digestion and DNA sequencing confirmed pcDNA3.1/MUC1-2VNTR/myc-his B including the whole exact translation frame region and MUC1-2VNTR gene.Condnsion The pcDNA3.1/MUC1-2VNTR/myc-his B has been successfully constructed,which provides the basic material for further studies of MUC1 mucin function and multiple myloma DNA vaccine.

Objective To evaluate the clinical outcome of external bracket fixation in the treat- ment of complex tibia diaphysis fracture involving intra-articular fractures.Methods Forty-two cases of complex tibia diaphysis fracture with proximal and distal intra-articular fractures treated surgically in our hospital from January 1999 to January 2004 were analyzed.The complex tibia diaphysis fractures were categorized according to the AO classification as type C2 (multiple segments fracture) and type C3 (ir- regular fracture),proximal and distal intra-articular fractures in 23 and 19 cases,respectively.Definite operation was done within one week.Twenty-two cases were treated with simple external fixator,and 20 cases treated with screws and external fixator.Results All the 42 cases were followed-up regularly. According to AO evaluation of the knee and ankle joint movement,83% (35/42 cases) of the cases gained satisfactory functional outcome,14% (6/42 cases) had quite satisfactory results and 2% (1/42 case) had unsatisfactory functional outcome.Conclusion External bracket fixation can obtain outcome of relative length of the tibia and fibula,tube structure reconstruction,smoothness of the articular surface and the parallel and symmetric relation of knees and ankles for complex tibia diaphysis fracture with proxi- mal and distal intra-articular fracture.The arthritis resulting in pain in movement and restriction of func- tion is considered to be the most important factor affecting the joint function.Early functional exercise is important for best recovery of knee and ankle function.

Objective To investigate the correlation between obstructive sleep apnea syndrome(OSAS)with myocardial ischemia and arrhythmia.Methods To observe the occuring rate of premature beats and change of ST- segment,90 eases of OSAS patients were detected by the polysomnogram(PSG)and dynamic electrocardiogram at the same time.Results Total morbidity of myocardial ischemia was 32.2 % in OSAS patients,and it was 59.4 %, 15.8 %,20 % in serious,moderate and mild groups respectively.There was a statistically significant difference be- tween the three groups and the control group(P0.05).Conclusion As one of the risky factors of cardiovascular diseases,OSAS can induce myocardial ischemia and arrhythmia.

Objective Analyse the change of left ventricular (LV) longitudinal and radial strain in patients with aortic regurgitation (AR) and discuss the relationship between the 2D strain parameter and the filling and ejection of LV. Methods Thirty healthy controls and 45 patients with AR (24 patients with moderate AR and 21 with severe AR) were enrolled in this study, LV systolic global peak radial strain(GRS), systolic global peak longitudinal strain(GLS) and systolic peak longitudinal strain(S), systolic peak longitudinal strain rate(SRs), early diastolic peak longitudinal strain rate(SRe) of every segment were measured or calculated using 2D-STE, early and late diastolic transmitral flow velocity (E, A) were recorded by pulsed Doppler echocardiography and early diastolic mitral annular velocity (Ea) were assessed by tissue Doppler imaging,the E/A and E/Ea ratio were calculated. Discuss the relationship of GLS and LV ejection fraction (LVEF), GLS and E/Ea using the Pearson correlation analysis. Results The GLS were (-20.09±1.47)%, (-18.68±1.52)%, (-12.56±3.25)%and the GRS were (46.71±7.65)%, (43.01±5.95)%, (28.52±6.13)% in control group, patients with moderate and severe AR (MAR group and SAR group) respectively. There were significant differences among the groups (F =82.08,47.69, both P < 0.01) as following:SAR group with control group and MAR group [ q=17.56,13.60 (GLS), q=13.44, 10.20 (GRS), all P<0.01),MAR group and control group [ q=3.42 (GLS), P<0.01]. The SRs of the apical segment were (-1.24±0.22)s-1, (-1.19±0.25)s-1, (-1.04±0.28)s-1 in control group,MAR group and SAR group respectively. There were significant differences among the groups (F=4.47, P < 0.05) as following:SAR group with control group and MAR group ( q=4.02,3.28, both P<0.01). The S, SRe of apical segment and the S,SRs,SRe of basal and midventricular in MAR group were all lower than the control group ( q=4.42, 5.01, 3.48, 3.24, 4.78, 4.12, 3.61, 6.72, all P < 0.01). Pearson correlation analysis revealed the GLS had a relationship with LVEF and E/Ea ( r=-0.73, 0.64, both P<0.01). Conclusion The reduced longitudinal strain and strain rate could detect LV dysfunction in patients with AR in early stage and the GLS had the ability to reflect the diastolic filling and systolic ejecting of the LV.
