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 explore the clinical effects of injecting methotrexate with hysteroscopic tubal can-nulation combined with Huayu shapei prescription in the treatment of salpingocyesis.Methods 82 unruptured salpin-gocyesis patients were randomly divided into the two groups.41 patients in the observation group were treated by hyst-eroscopic tubal cannulation injection of methotrexate combined with Huayu shapei prescription,41 patients in the con-trol group were treated by methotrexate intramuscular injection with oral mifepristone.The clinical efficacy of the two groups were observed,the level of serumβHCG required for tubal pregnancy,the mass absorption and after treatment of tubal patency.Results Compared with the control group,the difference was significant of the decline of serum βHCG in the treatment group (t=2.67,P<0.05).Compared with the control group,the treatment effectiveness and the absorption of the mass in fallopian tube in the treatment group,the difference was significant (t =3.57,P<0.05 ).Tubal patency detected treated group was superior compared with the control group,the difference was signifi-cant(χ2 =100.23,P<0.05).Conclusion Compared with traditional treatments,injecting methotrexate with hyste-roscopic tubal cannulation combined with Huayu shapei prescription in the treatment of salpingocyesis can effectively reduce the HCG levels,promote the absorption and softening of the ectopic pregnancy mass,to achieve the purpose of killing embryos eliminate micro,it will help to improve patients with clinical symptoms and signs,to maximize the recovery of the patient's reproductive function and physical health.

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 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.

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 explore the clinical efficacy of NEOVEIL in postoperative pulmonary air leakage of pulmonary bullae resection by video-assisted thoracic surgery. Methods We retrospectively analyzed clinical data of 37 cases received NEOVEIL combined with ATB45 in video-assisted thoracic surgery (the NEOVEIL group), and clinical data of 40 cases by ATB45 alone(the control group) . We compared postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary infection in the two groups. Results There was no postoperative mechanical ventilation,hemothorax and death. In the NEOVEIL group, the postoperative hospitalization time was 5 to 9 days, the postoperative keeping time of pleural cavity tubes 2 to 4 days, the postoperative pulmonary leakage time 0 to 2 days with 4 patients un-leakage, and 1 patients with pulmonary infection; whereas the postoperative hospitalization time was 6 to 10 days,the postoperative keeping time of pleural cavity tubes 3 to 6 days,the postoperative pulmonary leakage time 2 to 5 days and 8 patients with pulmonary infection in the control group. There was statistical significance in the postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary inflammation in two groups(P ＜ 0. 05). The incidence of pulmonary inflammation of the NEOVEIL group (2. 7%) was significantly lower than that of the control group(20. 0%)(x2 = 4. 02, P ＜ 0. 05). Conclusion The operative effectiveness of the NEOVEIL group is better than that of the control group. The NEOVEIL can prevent the postoperative pulmonary leakage.

Objective To evaluate the sunscreen application and the level of photoprotective knowledge in both dermatologists and photosensitive patients. Methods The style, sites and amount of the sunscreen applied were examined by 0. 05 % dipyridamole cream in 39 dermatologists and 41 photosensitive patients with Wood's light. The participants were asked to fill in a questionnaire about the photoprotective knowledge. Results Frequent mistakes made by participants in this study were as follow: (1) using an inadequate amount of sunscreen; (2) putting sunscreen in the palm of the hand and rubbing the hands together before application; (3) lacking a systematic approach to sunscreen application. The median quantity of individual sites ranged from 0. 5 mg/cm2 to 1 mg/cm2 except for the forehead of the female dermatologist that had a median thickness of 1. 5 mg/cm2. The questionnaire survey showed that dermatologists also had less knowledge on sun protection even though better than photosensitive patients. Conclusions Dermatologists and photosensitive patients always fail to apply sunscreen in some prominently exposed sites and to paint the average thickness of sunscreen used far less than that of experimentally measured dose (2 mg/cm2). Continuing education and training about pho-toprotection for dermatologists should be carried out to provide better education for the patients on sun protection.

Objective To evaluate the clinical significance of plasma ionized calcium (ICa) and total calcium (TCa) measurement in diagnosis of tumor-associated hypercalcemia. Methods The heparin lithium anticoagulated plasma were collected and measured with ion selective electrode (ISE) and orthocresolphthalein complexone (OCPC) method for ICa and TCa in 77 patients with malignant tumor (tumor group) and 44 healthy controls (control group). Meanwhile,plasma albumin and pH value were measured to correct TCa (cTCa) and ICa(nICa). The results were analyzed. Results The levels of cTCa,ICa and nICa in tumor group were significantly higher than those in control group(P＜ 0.01 ) ,but there was no significant difference of TCa between two groups (P ＞ 0.05 ). cTCa ＞ 2.70 mmol/L, nICa ＞ 1.35 mmol/L as the hypercalcemia eritical value, the positive rate of nICa and cTCa were 18.18% (14/77) and 6.49% (5/77)respectively,the difference was significant (P = 0.023). Conclusion Determination of ICa may be more clinical meaningful than TCa for tumor-associated hypercalcemia.
