Objective:To investigate the clinical characteristics of urinary system abnormalities in Chongqing and its surrounding area, and to assess the role of the large-scale urinary system ultrasound screening in the asymptomatic children with kidney and urinary tract abnormalities. Methods:We performed urinary system ultrasound on Screening 14 256 children from September 2008 to October 2008 in Chongqing Children’s Hospital. The total samples were allocated into five groups as follows:less than 1 year group;1 to 3 years group;3 to 5 years group;5 to 10 years group ;more than 10 years group. Then according to each group’s age,sex,disease location,severity difference,we performed statistical analysis. Results:409(2.87%)of 14 256 children had abnormalities,284 of whom was diagnosed with significant anomalies,including hydronephrosis,renal maldevepment (aplastic,dysplastic,hypoplastic,ectopic kidneys)and renal agensis,nephrolithiasis,simple renal cyst,multicystic dysplastic kidneys (MCKD),ureter dilation,duplex kidneys and so on. Among these anomalies,the most prevalent abnormal finding was hydronephrosis accounting for 130 cases,almost a half of 284 (45.77%),92 cases in males,38 cases in femal. The prevalence of melamine related urinary calculus was as 5.17 times as that of others and its 95% confidence interval(CI)of population relative risk was [3.28,8.14]. Conclusion:① Ultrasonography in the diagnosis of diseases of the urinary system can play an important role,especially for congenial anomalies of kidney and urinary tract(CAKUT)and /or hydronephrosis and so on. Therefore,an early diagnosis of these defects allows to realize as fast as possible the best medical and/or surgical treatment, preventing or at least slowing down the progression to chronic renal failure. ② The prevalence rate of hydronephrosis in male is higher than female. ③Exposure to melamine- contaminated formula is associated with urinary stones.

Objective: To study effects of tertiary rehabilitation training on upper limb motor function recovery in patients with cerebral hemorrhage.Methods: A total of 120 patients with cerebral hemorrhage, who were treated in our hospital from May 2013 to May 2015, were selected.According to random number table, they were randomly and equally divided into routine rehabilitation group and tertiary rehabilitation group, and both groups received the same routine medical treatment and nursing.Simple test for evaluating hand function scale (STEF), Fugal-Meyer motor assessment (FMA) and Brunnstrom limb motor function assessment were used to assess and compare limb recovery after rehabilitation training between two groups.Results: At the end of first month of rehabilitation training, there were no significant difference in STEF and FMA scores between two groups, P>0.05 both.On the end of second month of rehabilitation training and later, compared with routine rehabilitation group, there were significant rise in STEF score[end of second month: (3.3±0.5) scores vs.(4.2±1.1) scores, end of sixth month: (6.3±1.2) scores vs.(8.5±1.1) scores], total STEF score[(20.2±4.2) scores vs.(38.2±3.5) scores]and FMA score[end of second month: (28.4±3.6) scores vs.(33.4±2.7) scores, end of sixth month: (38.2±6.6) scores vs.(46.3±5.8) scores]in tertiary rehabilitation group, P<0.05 all.Compared with routine rehabilitation group after six-month rehabilitation training, there were significant rise in percentages of Brunnstrom stage V (23.33% vs.43.33%) and stage VI (6.67% vs.20.00%) in tertiary rehabilitation group(P<0.05 both).Conclusion: Tertiary rehabilitation training can significantly improve upper limb motor function in patients with cerebral hemorrhage, so it's worth extending.

BACKGROUND:Traditional Chinese medicine shares wide application in clinical treatment because of its high security. At present, a lot of studies have been reported, in which, traditional Chinese medicine or monomers are used for in vitro differentiation of bone marrow mesenchymal stem cells into cardiomyocyte-like cells.
OBJECTIVE:To summarize and analyze the research progress of Chinese medicine to induce the differentiation of bone marrow mesenchymal stem cells into cardiomyocyte-like cells and to looking prospect for its application.
METHODS:CNKI database was searched for the articles about Chinese medicine-induced differentiation of bone marrow mesenchymal stem cells into cardiomyocytes, published from January 2001 to January 2013. The key words were“Chinese medicine, bone marrow mesenchymal stem cells, cardiomyocyte”in Chinese and“bone marrow mesenchymal stem cells, myocardial cells”in English. Obsolete or repetitive articles were excluded. Final y, 36 articles were included in result analysis.
RESULTS AND CONCLUSION:Different Chinese medicine formulations were used as inducers to induce differentiation of bone marrow mesenchymal stem cells into cardiomyocytes, including Panax notoginseng saponins, salvianolic acid B, Jiawei Danshen Yin, icari n, astragaloside. Then, the induced cells were examined by immunohistochemistry and reverse transcription-PCR. The results showed that the induced cells were positive for Desmin, cardiac troponin I and major histocompatibility complex. Positive cells were fusiform and fibroblast-like morphology, which indicates a role in promoting proliferation and differentiation. These findings show that Chinese medicine-induced differentiation of bone marrow mesenchymal stem cells into cardiomyocytes has become a worldwide research hotspot, providing a theoretical basis for clinical treatment of ischemic heart diseases.

Objective To approach the involved position and regulation as well as the clinical characteristics of hereditary multiple exostoses(HME).Methods One HME pedigrees including men and women 7 cases respectively confirmed clinically and pathologically was analysed.Results The most common location of exostoses was metaphysis of long bones.No exostoses was found in craniofacial bone.Conclusion There is no sex difference in the incidence of HME and the location of exostoses is mostly at metaphysis of long bones in this family.

Objective: To evaluate the effect of dietary fiber and phytic acid inositol hexaphosphate (IP6 or Insp6) on 1,2-dimethylhydrazine(DMH) induced colorectal carcinogenesis in Wistar rats. Methods: 86 four-week-old male Wistar rats were divided randomly into 6 groups and fed with either basal fiber free diet or the basal diet supplemented with 10% pectin, 10% cellulose, 2% Na-InsP6 supplemented water, 10% pectin in combination with 2% Na-InsP6 supplemented water, 10% cellulose in combination with 2% Na-InsP6 supplemented water. After four weeks, the rats were given a weekly injection of DMH (20mg/kg bw) for 20 weeks. The rats were killed after 26 weeks. The number of total macroscopically visible neoplasms was counted and the volume of individual neoplasmas was calculated. Proliferation cell nuclear antigen (PCNA) was analyzed. Results: There was no significant difference between the treatment group and the control group in the incidence of tumors. InsP6 significantly reduced the number of tumors in rats and tumor volume. Pectin and Pectin+InsP6 significantly increased the number of tumors in rats. The expression of proliferation marker PCNA was significantly down-regulated by InsP6 and significantly increased by pectin. Conclusion: A treatment regimen of 2% Na-InsP6 in drinking water was effective in significantly reducing the risk of colorectal cancer in Wistar rats. Diet supplemented with pectin could increase the risk of colorectal cancer.

Objective To investigate the involvement of apoptosis in the lesions of patients with psoriasis. Methods The apoptosis was detected with terminal deoxynucleotidyl transferase mediated dUTP biotin nick end labeling (TUNEL), and the expression of p53, PCNA and apoptosis suppressing protein bcl 2 was assessed with immunoperoxidase technique in psoriatic lesions and normal skin. Results A large number of keratinocytes showing biochemical and morphologic features of cells undergoing apoptosis were observed in all the suprabasal layers of the psoriatic epidermis. The plaques from all patients analysed showed marked increase in the number of PCNA positive cells in the middle and basal keratinocytes, and a dramatic reduction in the number of bcl 2 positive cells in the basal cell layer. Conclusion The increased apoptosis of keratinocytes in the lesions of psoriasis might be a homeostatic mechanism to the hyperplasia of cells.
