Objective To analyze the clinical and radiographic characterstics of ureteral polyps with hydronephrosis in children.Methods Thirteen patients with ureteral polyps and hydronephrosis were studied retrospectively.All patients underwent abdominal plain film,intravenous pyelogram(IVP)and ultrasound(US)examinations,contrast-enhanced CT scan was performed in 10 cases.Results Intermittent or recurrent abdominal pain with painless hematuria was presented in most cases.Hydronephrosis was demonstrated in radiographic images.IVP delineated the dilatation of the ureter and filling defects within the ureteral lumen in 5 cases.Computed tomography(CT)showed all abnormal changes of ureter and irregular intraluminal soft tissue masses in 6 cases.Moderate and low echoic structures were showed in ureters by US in 2 cases.Conclusion US and CT,as an important imaging modalities,can improve the diagnostic accuracy for ureteral polyps.

OBJECTIVETo search for an effective therapy for vascular dementia (VD).

METHODSOne hundred and twenty cases of VD were randomly divided into 2 groups, 60 cases in each group. The observation group were treated with puncturing with needles in alignment at the hairline region and the control group with oral administration of Duxil. Hasegawa's dementia scale (HDS), mini-mental state examination (MMSE), functional activity questionnaire (FAQ), nerve function defect (NFD) and main symptoms (MS) scales were used for assessment of symptoms and signs before and after treatment.

RESULTSChanges of scores for HDS, MMSE, FAQ, NFD and MS before and after treatment had statistically very significant differences (P < 0.01) in the two groups, with significant difference between the two groups (P < 0.05). The total effective rate was 88.33% in the observation group and 81.67% in the control group with a significant difference between the two groups (P < 0.05).

CONCLUSIONPuncturing with needles in alignment at the hairline region has definite therapeutic effect on vascular dementia.

Studying on the acupoints in the hairline region of the scalp, it is discovered that a group of acupoints are orderly arranged in the hairline region of the scalp. Furthermore, the arrangement is highly consistent with the meridian route of zang-fu organs. Manipulating needles at acupoints in the hairline regions of the scalp may treat certain diseases, including insomnia, migraine, and Alzheimer disease. The characteristics of the acupuncture treatment at acupoints in the hairline of scalp resemble the characteristics of ear acupuncture and eye acupuncture. Thus forms a special micro-acupuncture system in the hairline regions of the scalp. This paper states the theoretical basis, the arrangement of acupoints, clinical application and operating norms.

OBJECTIVETo search for the morphological evidence of five-shu-point so as to explain the theory of the five-shu-point more reasonably.

METHODSCarefully study on Yellow Emperor's Internal Classic and compare with the modern anatomic knowledge.

CONCLUSIONThe theory of five-shu-point is closely related with the theory of blood vessels. The distributional pattern of the superficial vein on the remote parts of the limbs (below the elbow or the knee joints) is the morphological basis for the theory of five-shu-point.

OBJECTIVETo explore the relationship between two exonic polymorphisms of DNA repair gene XPC and the susceptibility to lung cancer.

METHODSGenotypes were determined by the primer introduced restriction analysis-PCR(PIRA-PCR) and the PCR-restriction fragment length polymorphism(PCR-RFLP) approaches, respectively, in 320 histologically-confirmed lung cancer cases and 322 age and sex frequency-matched cancer-free controls.

RESULTSMultivariate logistic regression analysis revealed that individuals carrying at least one 499Val variant allele (Ala/Val + Val/Val genotypes) had a significantly increased risk for lung cancer (adjusted OR=1.54; 95%CI: 1.11-2.14), compared with the wild-type genotype (499Ala/Ala). Furthermore, individuals with both putative risk genotypes had a significantly higher risk (adjusted OR=2.55; 95%CI: 1.45-4.52), compared with those with both wild-genotypes. In addition, a potential super multiplicative gene-environment interaction between Ala499Val genotypes and smoking on lung cancer risk was unveiled. The odds ratios of lung cancer for individuals with both putative risk genotypes were 2.63 (95%CI=1.23-5.62) in nonsmokers and 7.36 (95%CI=3.19-17.0) in smokers, respectively.

CONCLUSIONThese findings support the hypothesis that these two XPC variants may contribute to the risk of developing lung cancer.

OBJECTIVETo search the etiologic factor, clinical diagnosis points and treatment of postoperative intussusception (PI).

METHODSTo retrospectively review the clinical materials of 14 cases with PI including the cause of disease and treatment.

RESULTSPI occurred within 10 days (average 4 days) after the primary operation. Bowel obstructive symptoms gradually emerged. One case was diagnosed with intussusception by sonography and received enema reduction of intussusception by hydrostatic pressure. Thirteen cases were performed secondary operation. Small intestine was main site of intussusception. Manual reduction of the lesion was performed in 12 cases and bowel resection and anastomosis was done in 1 case with bowel necrosis.

CONCLUSIONPI should be suspected if child presents with the symptoms of ileus in early postoperative period. Abdominal sonography may have some value on diagnosis of PI. Operation is the first choice for the treatment of PI.

OBJECTIVETo study the expression of signal transducer and activator of transcription 3 (Stat3), hypoxia-inducible factor-1alpha (HIF-1alpha) and vascular endothelial growth factor (VEGF) in Wilms' tumor and their roles in the development of Wilms' tumor.

METHODSThe expression of Stat3, HIF-1alpha and VEGF were detected by the immunohistochemical staining in 52 specimens from Wilms' tumor tissues, 47 from adjacent kidney tissues and 8 from normal kidney tissues. The expression intensity was analyzed by computer image processing.

RESULTSThe expression of Stat3, HIF-1 and VEGF were significantly up-regulated in Wilms' tumor tissues compared to those in adjacent tissues and normal kidney tissues (P < 0.05). Stat3 and VEGF proteins in Wilms' tumor tissues of stage III-IV and high risk histopathology were significantly higher than those of stage I-II and low risk histopathology. The higher expression of HIF-1 in Wilms' tumor tissues was shown in tumors with high risk histopathology and tumor size > or = 6 cm.

CONCLUSIONSIncreased expression of Stat3, HIF-1 and VEGF were found in Wilms' tumor tissues, and may be related to the development and angiogenesis of Wilms' tumor. Stat3 may regulate the expression of HIF-1 and VEGF, so it could be an effective target for inhibiting VEGF expression and angiogenesis of Wilms' tumor.

Objective To observe the efficacy of tirofiban in the treatment of ischemic progressive stroke. Methods 300 patients who met the diagnostic criteria of ischemic progressive stroke were divided into the control group and tirofiban group. Patients in the control group received treatment of PA2S regiment, i.e., a combination of aspirin, clopidogrel, probucol and atorvastatin. Patients in the tirofiban group received extra tirofiban on the basis of PA2S therapy. National institute of health stroke scale (NIHSS) score was evaluated on patients in both group before the therapy and 3 days, 1 month, 6 months after the therapy respectively. Results For the control group, the average NIHSS score was 11.3±4.2,11.5±4.4,8.8±4.1,6.1±4.1 before therapy and at 3 days, 1 month, 6 months after the therapy. And for the tirofiban group, the average NIHSS score was 11.4±3.9, 10.8±3.6, 7.4±3.2, 4.4±3.0 at the corresponding period respectively. There were statistical differences between the two groups in the period of 1 month and 6 months after treatment with P<0.001. Conclusions Tirofiban hydrochloride can improve the degree of neurological deficit and outcome in patients with ischemic progressive stroke.

OBJECTIVETo compare the difference of polycyclic aromatic hydrocarbons (PAHs) levels in the urban air and the scores of Neonatal Behavioral Neurological Assessment (NBNA) between Taiyuan and Changzhi cities and to explore the effects of PAHs in the urban air during pregnancy on neonatal behavioral neurological development.

METHODSHigh-performance liquid chromatography (HPLC) with subsequent fluorescence detection was used to determine the PAHs levels in the cooperational hospitals in Changzhi and Taiyuan cities and the urinary 1-hydroxypyrene levels of the 297 pregnant women living Changzhi and Taiyuan cities during Nov. 2009 to May 2010. NBNA was used to determine the development of neonatal neural behavior. The differences of PAHs levels in the urban air, the pregnant women urinary 1-hydroxypyrene levels and NBNA scores between Taiyuan and Changzhi were compared.

RESULTSThere are significant differences of levels of pyrene, benz [a] anthracene, Chrysene, benz [a] pyrene, dibenz [a, h] anthracene in the urban air between Taiyuan and Changzhi (P < 0.10). The median of urinary 1-hydroxypyrene levels in pregnant women of Taiyuan was 1.140 microg/mmolCr, (P25 was 0.457 microg/mmolCr, P75 was 2.678 microg/mmolCr), the median of urinary 1-hydroxypyrene levels in pregnant women of Changzhi was 0.761 microg/mmolCr, (P25 was 0.133 microg/mmolCr, P75 was 2.095 microg/mmolCr). There are significant differences of urinary 1-hydroxypyrene levels in pregnant women between Taiyuan and Changzhi (t = -3.140, P = 0.002). There are significant differences of the NBNA scores, capacity scores, passive muscle tension scores, active muscle tension scores and general assessment scores between Taiyuan and Changzhi (P < 0.10). There was correlation between NBNA scores and urinary 1-hydroxypyrene level in pregnant women.

CONCLUSIONThe PAHs in the urban air during pregnancy may adversely affect the neonatal neurobehavioral development.
