Stone retropulsion during ureteroscopic lithotripsy is a common troublesome problem for most urologists. Stone retropulsion can result in increase in health care cost and increased operative time. With the popularisation of ureteros?copy, additional procedures to treat residual migrated fragments has drawn more and more attention and research. In recent years, many equipment, devices and techniques are designed to resolve this big puzzle. We reviewed the literatures to sum?mary the strategy for preventing stone retropulsion during ureteroscopic lithotripsy.

Objective To investigate the new method of ureter bladder anastomosis in renal transplantation.Methods The ureter was pulled into bladder for 1.2 cm through tunnel at the lateral- top of bladder wall,and the ureter fixed on the bladder wall by 2-3 acus with catgut suture.Results Forty of 42 patients had no complications,and recovered very well,except for 1 cases of necrosis caused by acute rejection and 1 case on urine leakage caused by catheter obstruction from blood clot.Conclu- sion This method is simple,easy to operate,safe and reliable with less complications.

OBJECTIVETo investigate the impacts of biological factors (age and sex) and family factors (socioeconomic status and parenting style) on the early lexical and intellectual development of children in a longitudinal tracking study.
METHODSA total of 38 Mandarin-speaking children aged from 18 to 24 months were surveyed using the Putonghua Chinese Communicative Development Inventory (PCDI), the Ages and Stages Questionnaire (ASQ), and a self-designed Questionnaire for Parents. All of the subjects were retested using PCDI and ASQ after 6 months.
RESULTSBiological factors accounted for 65% of the variance in lexical development, 10% of which was attributed to gender, in the first survey. After six months, the contribution of age decreased to 26% and gender had no significant impact. Lexical development could positively predict the intellectual development of children. When age and gender were controlled, it accounted for 22% of the variance in intellectual development. Family socioeconomic factors had no significant impacts on lexical and intellectual development. Children's recognition of people and objects around them with guidance of parents in parenting styles could positively predict the intellectual development of children six months later, which accounted for 10% of the variance.
CONCLUSIONSBiological factors play an important role in the early lexical development of children. However, the influence decreases with the increase of age (months). Biological factors, lexical development, and parenting style have a combined influence on children's intellectual development.

OBJECTIVEA study was conducted to investigate the relevant applied technique and clinical value of endoscope-assisted repair of zygomatic arch fracture.
METHODSA total of 10 cases of unilateral zygomatic arch fracture and 8 cases ofunilateral zygomatic fracture were included. Reduction and fixation of the zygomatic arch in all cases were performed via asmall face incision by an endoscope. Endoscope-assisted repair allowed exposure of zygomatic arch fracture and ended the anatomy of the reset. Zygomatic arch was stabilized with titanium plates.
RESULTSSymmetric malar was achieved in allcases after operation. Patients did not show difficulty in opening the mouth. No chewing problems or severe complicationswere evident. This method had the advantage of hidden incision, and it did not leave scars on the face. Postoperative CT examination showed excellent reduction of zygomatic arch fracture and good fixed position of titanium plate.
CONCLUSIONEndoscope-assisted repair of zygomatic arch fracture via a small face incision can be an alternative operation for zygomaticarch fracture. Patients are less traumatized. There are fewer complications. A good reduction of fracture is achieved.

Objective:To study the efficacy of stereotactic radiotherapy (SRT) combined with gemcitabine plus cisplatin (GP)-based chemotherapy on local recurrent non-small-cell lung cancer (NSCLC) after radiotherapy. Methods:Thirty-eight patients with local recurrent NSCLC were treated with SRT(3.00-4.85 Gy per fraction, five times every week, totally 8-12 fractions, total course of 2-3 weeks). Before SRT the patients were given two cycles of GP-based chemotherapy (gemcitabine 1 000 mg/m~2 d 1 and d 8;cisplatin 30 mg/m~2 d 1-3) and at the end of SRT they were given 4 cycles of GP-based chemotherapy. Results:Of the 38 patients,7 patients had complete response, and 23 patients achieved partial response. The overall immediate response rate was 78.95% (30/38). The 6-month and 12-month total survival rates were 71.05% and 10.53%,respectively. The median survival time was 7.8 months. Conclusion:SRT combined with GP-based chemotherapy had better short-term efficacy and the patients were tolerable. No severe short-term radiation-induced injury was observed. The long-term radiation-induced injury and long-term efficacy need further investigation.

Background and purpose:In in vivo and vitro studies, Rhodiola shows anti-cancer effect, but there were few reports about the effects of Rhodiola on growth of breast cancer and its possible mechanism. Methods:Xenograft of Human breast cancer cells MDA-MB-435 in female BALB/c nude mice were treated with and without Rhodiola extracts. The tumor volume and proliferation index (PCNA and Ki67) of the xenograft were studied.Results:After Rhodiola was given to nude mice for 4 weeks, the mean tumor volume was smaller (99.95mm 3 vs. 174.60mm 3 ) compared to untreated group,but there was no statistical significance(P=0.535). The proportion and intensity of cellular Ki-67 staining in Xenografts were decreased as compared to the untreated group, (average H-score 152.8 vs. 86, P=0.014), the same trend could be found for cellular PCNA staining, but there was no statistical significance(242 vs.210,P=0.221).Conclusions:The mechanism of anti-cancer effect of Rhodiola may be partly through inhibiting the proliferation of cancer cells in vivo.

Objective To investigate the role of NF-κB activation in the inflammatory mechanism of chronic obstructive pulmonary disease (COPD).Methods Monocyte were collected from patients with COPD and were cultured,and stimulated with lipopolysaccharide (LPS) ; NF-κB p65 activation was measured by immunohistochemistry; SOD ,MDA and IL-8 and lung function were determined synchronously.Results The NF-κB p65 was induced by LPS in monocyte in all subjects, but it was most markedly done in COPD patients with exacerbateions; There was positive correlation between the NF-κB p65 activation of monocytes and levels of IL-8 and MDA in circulation, but it was negative correlation to SOD.Conclusion NF-κB plays a vital role in regulating product of IL-8 in monocyte in COPD.

Objective; To evaluate the influence of electrolyte's concentration at micro-arc oxide treatment on the bonding strength of titanium to porcelain. Methods; CP titanium specimens with size of 25 mm ×3 mm ×0. 5 mm were treated with micro-arc oxidation (MAO) in Na_2SiO_3 solution of three different concentrations. After ultra-low-fusing porcelain was applied, a three-point-flexure-test was used to evaluate the bonding strength of titanium to porcelain. The surface of the specimens was observed by SEM and EDS, as well as the interface between titanium and porcelain. Results; The bonding strength values between titanium treated with MAO and porcelain was significantly higher then the control groups, Croup 20 g/L has the highest bonding strength values. SEM/EDS suggested that a porous thin layer of oxide which contains Si element is created by MAO, and higher concentration of Na_2SiO_3 leads to more Si element in oxide. Conclusion; MAO treating can improve the bonding strength between titanium and ceramic. Electrolyte's concentration has an effect on the bond strength between titanium and porcelain.
