Objective To explore the correlation between personality traits in children and parental rearing patterns.Methods Two hundred and seventy-nine middle school students were investigated with egma minnenav bardndasnauppforstran(EMBU)and Eysenck personality questionnaire,and then Pearson correlation was analyzed.Results High positive correlation were found among scores of parental rearing patterns and those of neuroticism(N)and psychoticism(P).P score correlated significantly with parent's punishment,rejection and negative reaction,over interference and over protection,while high negative correlation with the score of parent's emotional warmth.N correlated significantly with parent's punishment,overprotection and rejection,high positive correlated the score of lie with parent's emotional warmth.Conclusion Parental rearing patterns play very important roles in children's personality development.

Objective To describe the single needle running suture method for the urethrovesi-cal anastomosis during laparoscopic radical prostatectomy(LRP). Methods Forty-five patients of prostate cancer underwent LRP with the single needle running suture method. The technique was initi-ated by performing a fixing suture at the posterior lip of bladder neck at 4 o' clock and tying the first knot. Another suture at the nearby position of the first suture was performed to leave the first knot outside. From 5 o' clock to 8 o' clock, sutures were performed every one o' clock to secure posterior approximation, then every two o'clock a suture. To avoid a loose anastomosis, lock sutures were per-formed every 3 sutures. After completing the full circumference, the needle was drawn at the 2 o' clock for the second knot. The needle was always driven full-thickness outside-in in the bladder neck and inside-out on the urethra. Any remaining leakage could be closed with additional interrupted su-tures. Results All urethrovesical anastomosis were completed successfully. The mean anastomosis time was 16 rain(from 12 to 25 min), and mean operative time was 132 rain (112 to 185 rain). The mean catheterization time was 9 d(7 to 14 d). Three temporal urinary leaks requiring prolonged cathe-terization were identified. Forty-four patients had total urinary control in 1 year postoperatively and no other short-term or persistent complication was found with a mean follow-up of 21 months. Conclu- sion The single needle running suture method could be a simple and safe method for urethrovesical anastomosis during LRP.

Objective To explore the parental personality traits and affective expression in abuse children.Methods The investigation was carried out in 3 villages in Xinxiang,Henan province,with a total of 1 310 households,of which there were altogether 370 households that had children at 10-15 years old.From them,200 households were randomly selected to screen the children for child abuse,and the Eysenck Personality Questionnaire (EPQ) and Toronto Alexithymia Scale(TAS) assessment were made among the parents who were primary caregi-vers.Independent samples t-test and Chi-square test were conducted to the 196 valid questionnaires.Results The average educated years of parents in abuse group and non-abuse group were (7.75?5.437)years old and (7.28? 2.532) years old,there was no significant diffe-rence (P=0.413).The average age of fathers in abuse group and non-abuse group were (36.16?8.96)years and (39.06?7.99)years repectively,there was no significant difference(P=0.170),and those of mothers in both groups were (36.06?5.15)years and (37.62?5.70) years respectively,there was no significant difference(P=0.121).There were 31 fathers and 49 mothers who were guardian in abuse group,while there were 35 fathers and 81 mothers in non-abuse group (?2=1.56 P=0.212).No significant differences were found in parental psychoticism [t(father)=1.221 P= 0.227;t (mother)=-0.471 P=0.639],neuroticism[t (father)=-0.524 P=0.602;t(mother)=-0.556 P=0.579],extraversion/ introversion[t(father)=-0.449 P=0.655;t(mother)=-0.859 P=0.392] and lie [t(father)=-1.263 P= 0.211;t(mother)=0.733 P= 0.465],the ability to identify and describe feelings[t(father)=0.946 P=0.348;t(mother)=0.815 P=0.417],to distinguish between bodily sensations[t(father)=0.215 P=0.831;t(mother)=2.107 P=0.037],to daydream [t(father)=-0.088 P=0.930;t(mother)=-0.971 P=0.333]and to focus on externally oriented thinking[t(father)=-0.648 P= 0.519;t(mother)=-0.164 P= 0.870] in TAS.Conclusions In a general way parents who abuse their children do not necessarily have problems with their personalities or affective expression.Not only abnormal parents are likely to assault their children,but also normal parents may do it as well.

The expression of KAI1/CD82 and MRP-1/CD9 in transitional cell carcinoma of bladder (TCCB) and its clinical significance were investigated. Immunohistochemistry was used to detect KAI1/CD82 and MRP-1/CD9 protein expression in 52 TCCB specimens. Correlation between the expression of KAI1/CD82 and MRP-1/CD9 to clinicopathologic factors was statistically analyzed. The results showed that the positive rate of KAI1/CD82 and MRP-1/CD9 in TCCB was 50% and 61.5%, respectively. The MRP-1/CD9 and KAI1/CD82 expression was significantly associated with grade of TCCB (P<0.05), but no correlation was found between MRP-1/CD9 or KAI1/CD82 expression and clinical stage of TCCB (P>0.05). The expression level of MRP-1/CD9 and KAI1/CD82 in recurrent TCCB samples was lower than that in non-recurrent samples (P<0.05). Meanwhile, the correlation between the KAI1/CD82 expression and MRP-1/CD9 expression was statistically significant (r=0.316, P<0.05). It was concluded that KAI1/CD82 and MRP-1/CD9 expression may be important prognostic indicators and potentially useful for assessing the biological behavior of TCCB.

The single needle method for urethrovesical anastomosis with strengthened posterior fixation during laparoscopic radical prostatectomy was explored. The method was initiated by performing a fixing suture with a knot at 4 o'clock of the posterior lip of bladder neck, and another suture at nearby position was performed to leave the knot outside. From 5 o'clock to 8 o'clock, sutures were performed every one o'clock to secure posterior approximation, then every two o'clock a suture. To avoid a loose anastomosis, lock sutures were performed every 3 sutures. The needle was always driven full-thickness outside-in in the bladder neck and inside-out on the urethra. After completing the full circumference, the needle was drawn near the 4 o'clock and tied at the tail end. Any leakage could be closed with additional interrupted sutures. The clinical data of 89 patients who underwent this method were retrospectively compared with those of 23 patients who underwent the single knot method. The results showed that the anastomosis, operative and catheterization time was 17.6+/-4.7 min, 134.0+/-10.7 min and 6.5+1.6 days respectively. There were 3 temporal urinary leakages identified in 89 cases requiring prolonged catheterization. No urinary leak and anastomotic stricture was confirmed, and 95.2% patients had total urinary control. It was concluded that this method was simple and safe for urethrovesical anastomosis.

Objective To investigate the in vitro effects of bladder cancer cell proliferation after silencing Notch1 gene. Methods The siRNA eukaryotic expression vector of Notch1 (psiRNA1)was constructed and transfected into bladder cancer cell lines T24 and BIU-87. Methabensthiazuron (MTT) and flow cytometry (FCM) assays were used to detect bladder cancer cells line growth, cell cycle and apoptosis after the transfection. RT-PCR and Western blotting were used to determine the expression changes of Notch1 in these cell lines. Results After transfection for 72 h, the rate of G0/G1 phase cells inceased from (23.89±1.32) % to (80.13±2.69)% in T24 cell line, and increased from (24.63±1.68)% to (69.44±2.41)% in BIU-87 cell line (both P<0.05). In addition, apop-totic cell index in T24 and BIU-87 cell lines increased from (1.28±0.14)% to (13.75±1.23)%, from (1.01±0.27)% to (8.72±1.01)%, respectively(both P<0.05). The growth of T24 and BIU-87 cell lines was obviously inhibited 24 h after the transfection, and the inhibitory effects lasted until 96 h after the transfection. Notch1 mRNA and protein significantly downregulated after transfection compared to the control(P<0.05). Conclusions Silencing Notch1 expression can inhibit the prolif-eration of bladder cancer cell lines. Notch1 gene might act as a tumor gene in bladder cancer.

OBJECTIVETo investigate the pathogenicity of Leptospira interrogans fliR gene to J774A.1 cells.

METHODSfliR gene from L. interrogans serogroup Icterohaemorrhagiae serovar lai strain 56601 and kana gene from plasmid pET42a were amplified by PCR. Suicide plasmid of fliR gene was constructed; and specific siRNA for fliR gene was designed and synthesized. fliR gene mutants were constructed by gene knock-out with suicide plasmid (56601fliR-Kana) and gene silencing with siRNA (56601siRNA-R2). The mutants were identified by PCR, sequencing and semi-quantitative RT-PCR. Adhesion to mouse mononuclear-macrophage J774A.1 and induction of cell necrosis and apoptosis by 56601fliR-Kana and 56601siRNA-R2 were examined by adhesion test and flow cytometry, respectively.

RESULTThe nucleotide and putative amino acid sequences of cloned fliR gene had 99.9% and 100% similarities to those of reported sequences in GenBank. The nucleotide sequence of the cloned kana gene was identical to the corresponding sequence in pET42a map. The results of PCR and sequencing confirmed that kana gene was inserted in the sequence of 56601fliR-Kana fliR gene. The mRNA level of fliR gene in 56601fliR-Kana was remarkably decreased (P<0.01) while the mRNA level of fliR gene in 56601siRNA-R2 was much lower than that in wild strain 56601 (P<0.05). 56601fliR-Kana and 56601siRNA-R2 lost the ability to adhere J774A.1 cells; and their ability to induce cell necrosis and apoptosis was markedly weakened (P<0.01).

CONCLUSIONfliR is a virulence-associated gene of L. interrogans and the function of the gene is closely related to adhesion, induction of cell necrosis and apoptosis of the microbe.

The aim of this study was to observe the electrophysiological characteristics of the isolated rat muscle spindle. The muscle spindle was isolated from rat soleus and the afferent discharge of the isolated muscle spindle was recorded by air-gap technique. In the basic physiological salt solution, the spontaneous impulses of muscle spindle were at a lower level with irregular intervals. The mean frequency of afferents was (51.78 ± 25.63) impulses/1 000 s (n = 13). The muscle spindle afferents were significantly increased and maintained over time by the addition of certain amino acids during the observation. The number of the action potential recorded per 1 000 s was 200-1 000 [mean: (687.62 ± 312.56) impulses/1 000 s, n = 17]. In addition to the typical propagated action potential, a large number of abortive spikes were observed. The results indicate that the activities of isolated muscle spindles in rats can be well maintained by the addition of certain amino acids. The results initially establish and provide the possibility for further research conducted in isolated rat muscle spindles.
