There are two populations of bacteria to affect the formation of urinary stones in humanity. The first one can promote the formation of urinary stone by increasing urinary pH, decreasing concentration of urinary inhibitors , and damaging the protective urothelial glycosaminoglycan layer. The second inhibit the formation of urinary stones. These bacteria ( mainly the intestinal oxalate degrading bacteria such as Oxalobacter formigenes, lactic acid bacteria, Enterococcus faecalis etc) can decrease urinary oxalate concentration by regulating exogenous oxalate. The problems faced and the developing direction were also indicated.

Objective To evaluate the effectiveness of suberselective uterine arterial embolization for uterine fibroids.Methods Uterine arterial embolization with golyvimylalcohol(PVA) particles or Iodized oil and Gelfoam or Pingyangmycin lipiodol and Gelfoam was performed in 182 patients with uterine fibroids.Results Bilateral and unilateral superselective uterine arterial embolization were performed in 173 cases and 9 cases respectively. 6～28 months (mean 11 months) after the procedure, complete disappearance of tumor(16 cases), an average shinkage of 67% in tumor volume(152 cases) and a mean 42% reduction of uterine volume were obtained in 168 followed-up cases. The clinical symptoms were relieved significantly.The main side effets were hypogastic pain(135/182).Conclusion Superselection uterine arterial embolization is an effective and microinvasive method in treating uterine fibroids.

Objective To investigate the effects of partial body weight supported treadmill training (BW- STT) on post-stroke depression (PSD) and on patients' quality of life.Methods Sixty patients with PSD were re- cruited and divided into a training group (n=30,male 17,female 13) and a control group (n=30,male 16,fe- male 14).All patients were treated with routine internal medication and rehabilitation.The patients of the training group also received BWSTT in addition to their routine treatment.All patients' neurological impairment was evaluated using the Modified Edinburgh-Scandinavian Stroke Scale (MESSS).The Hamilton depression scale (HAMD) was used for evaluating the degree of depression.The Fugl-Meyer scale and the Barthel index were used to assess ambula- tion and balance,and facility in the activities of daily living.All patients were assessed before and after the treat- ment.Results After four weeks of treatment,depression in the training group had improved significantly more than in the control group.Conclusion BWSTT intervention is very important for patients with PSD:it can reduce the degree of depression and improve the quality of life.

Objective: To explore the relationship between gross motor development and perceived motor competence among children aged 7-8 years old. Methods: Random cluster sampling method was used to conduct a test among 162 students aged 7-8(78 boys,84 girls)by using Test of Gross Motor Development Ⅲ(TGMD-3) and 3 and Pictorial Scale of Perceived competence and Social Acceptance for Young Children(PSPC-P). Results: There were no statistical significance of perceived motor competence in different genders,and ages among children(t=-0.82, -0.58, P>0.05). Gross motor development differed significantly in different age groups (t=-4.79, P<0.01). Eight-year-old group(63.10±5.70) scored higher than 7-year-old group(57.96±7.76).There exists clear association between gross motor scores and perceived motor competence (r=0.29, P＜0.01), as well as locomotor development and manipulative development with perceived motor competence (r=0.21, 0.24, P<0.05). Conclusion There are close correlations between gross motor development and perceived motor competence among children aged 7 to 8 years. Manipulative development shows obvious influences on perceived motor competence. No gender differences are found in perceived motor competence.

Banana bunchy top virus (BBTV) is the pathogen of banana bunchy top disease (BBTD); it seriously disserves the banana production. This paper reviewed the separation and purification methods, classifying and taxonomy status of BBTV; the genome structure and function of each encode protein of the virus; and the present problems that should be further clarified.

OBJECTIVETo explore anti-cancer effect and mechanism of green tea extract (GTE) in three human oral squamous carcinoma cell lines (CAL-27, SCC-25 and KB).

METHODSThe cell lines were in vitro cultured and its growth inhibition was detected by MTT. After screening most sensitive cell line, effect of GTE on CAL-27 cell cycle was analyzed by flow cytometry. The protein expression of GTE on CAL-27 cell strain was determined by protein chip technique. The protein expression of CDK4, CDK6, and p-PDK1 was verified by using Western blot.

RESULTSCompared with the control group, the inhibition rate on CAL-27 increased significantly after treated by 50, 100, 200, and 400 μg/mL GTE; the inhibition rate on KB increased after treated by 100, 200, and 400 μg/mL GTE; the inhibition rate on SCC-25 increased after treated by 25, 50, 100, 200, and 400 μg/mL GTE, all with statistical difference and in dose dependant manner (P < 0.01). Flow cytometric analysis showed that, when compared with the control group, 50 μg/mL GTE arrested CAL-27 cells in the G2/M phase (P < 0.05), and 100 μg/mL GTE arrested CAL-27 cells in the G2/M phase with concurrent decreased cells in the G0/G1 phase (P < 0.01). Totally 107 proteins were analyzed by protein chip technique. After treated by GTE, a total of 13 proteins significantly changed in CAL-27 cell line. Western blot showed that 25, 50, and 100 μg/mL GTE inhibited the expression of phopho-phosphoinositide-dependent protein kinase 1 (p-PDK1), cyclin-dependent kinase 4 (CDK4), and CDK6 of CAL-27 cell line with statistical difference (P < 0.05). The higher the drug concentration, the higher the inhibition rate (P < 0.05).

CONCLUSIONSGTE could inhibit the proliferation of different human oral squamous carcinoma cell lines. CAL-27 is a sensitive cell line. GTE significantly affected EGFR and Notch signal network, and influenced changes of cell cycle related protein expression levels through the aforesaid channels, resulting in cell cycle arrest in S and G2/M phases.

BACKGROUND/AIMS: To evaluate the expression of CXC motif chemokine receptor 4 (CXCR4) in the tissues of patients with hilar cholangiocarcinoma (hilar-CCA) and to investigate the cell proliferation and frequency of neural invasion (NI) influenced by RNAi-mediated CXCR4 silencing. METHODS: An immunohistochemical technique was used to detect the expression of CXCR4 in 41 clinical tissues, including hilar-CCA, cholangitis, and normal bile duct tissues. The effects of small interference RNA (siRNA)-mediated CXCR4 silencing were detected in the hilar-CCA cell line QBC939. Cell proliferation was determined by MTT. Expression of CXCR4 was monitored by quantitative real time polymerase chain reaction and Western blot analysis. The NI ability of hilar-CCA cells was evaluated using a perineural cell and hilar-CCA cell coculture migration assay. RESULTS: The expression of CXCR4 was significantly induced in clinical hilar-CCA tissue. There was a positive correlation between the expression of CXCR4 and lymph node metastasis/NI in hilar-CCA patients (p<0.05). Silencing of CXCR4 in tumor cell lines by siRNA led to significantly decreased NI (p<0.05) and slightly decreased cell proliferation. CONCLUSIONS: CXCR4 is likely correlated with clinical recurrence of hilar-CCA. CXCR4 is involved in the invasion and proliferation of human hilar-CCA cell line QBC939, indicating that CXCR4 could be a promising therapeutic target for hilar-CCA.
