Objective To evaluate the surgical technique and clinical application of retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy with no suture of the incision. Methods Twenty-five patients who had upper urinary tract calculi with the course from 10 months to 6 years were enrolled.The size of the calculi was 1.2 to 3.1 cm in diameter.ESWL was ineffecative in 14 of the patients and ureteroscopic lithotomy failed in 2 of them.Then the 25 patients underwent retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy.Details of the procedure were presented. Results All the operations were successful in the 25 patients. The operations took 60 to 190 min with a mean time of 105 min.All the patients fully recovered with no complication observed during the 9～12 months' follow-up. Conclusions Retroperitoneal laparoscopy surgery with no suture of the incision has advantages of minimal invasive,safe,effective and rapid postoperative rehabilitation.The surgical procedure has a good prospect in the urologic clinical practice.

Objective To study the correlation between ths DSA manifestations and expression of serum VEGF in the patients with cervical cancer.Methods Imaging data of 40 cases with cervical cancer confirmed by clinic were collected,and DSA were performed during interventional therapy in all cases,and the serum VEGF was detected by enzyme-linked immunosorbent assay(ELISA)which was compared with that in 40 healthy women as contrast.Results(1)Serum VEGF level in the patients with cervical cancer was significantly higher than that in control group(P＜0.01),and the serum VEGF level was significantly higher in Ⅲ and Ⅳ stage of cervical cancer than that in Ⅱ stage(P＜0.05).(2)There was positive correlation between tumor stain in DSA and the serum level of VEGF(P＜0.05).Conclusion There was positive correlation between the degree of blood supply and the serum level of VEGF.

Basic fibroblast growth factor(bFGF)is a polypeptide cell growth factor,which has exten- sive physiological functions.With the in-depth study,the exploration of relationship between basic fibroblast growth factor and tumor has been developing rapidly in recent years,It shows a good prospect in diagnosis and treatment of tumor.There is a brief overview about the molecular biology of bFGF,its expression in tumor and the relationship between bFGF and tumorigenesis.

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.

Objective To evaluate the results of prosthesis augmentation,relieve suffering patient experience,improve shape and touch of breast.Methods According to design,in dual-plane mammaplasty transaxillary approach with endoscopic assistance,we used soft-tissue expansion before prosthesis,saline volume in expander was the same as prosthesis size at beginning; adjusting expander volume and position,then determined prosthesis size according to expander volume lastly.after intraoperative sustained expansion for 30 to 60 minutes twice prosthes volume,replace expander with prosthesis.Results This method was applied in 120 patients,showing that pain significantly reduced after expansive without use of analgesia pump; complications included that 3 patients appeared seroma and absorbed soon; 2 patients had poor prosthese location,which was adjusted in reoperation; one capsular contracture was repaired later.After 6-months to 2-years follow-up,the results showed that breast was nature and dynamic; satisfactory rate reached to 95 ％.Conclusions In augmentation mammaplastic operation,pre-adoption of an expander can make it easy to adjust the location of prosthesis,to avoid being injured and to determine prosthesis volume by expander injection of saline volume,especially for patient with different size of both breasts.

Objective To investigate the effects of dynamic standing bed training on the functional recovery of hemiplegic patients. Methods Sixty hemiplegic patients with Barthel index score of 40 were randomized into a standing rehabilitation group and a control group. The patients in standing rehabilitation group were asked to take part in dynamic standing bed training in addition to drug treatment. Those in the control group were treated with medication only. After 1 to 2 weeks of treatment, the weight-bearing ability of the lower limbs, balance, muscle tone, trunk control and the cardiovascular response were evaluated and compared with those before the treatment. Results The scores of weight-bearing, balance, muscle tone and trunk control of the patients in the standing rehabilitation group were better improved than those in the control group. The changes of blood pressure and pulse of patients were reduced and within the range of safety after 2 weeks of training. Conclusion Dynamic standing bed training is beneficial for the functional recovery of hemiplegic patients. It is safe for the patients in terms of cardiovascular response.

To explore the clinical significance of serum cardiac troponin I (cTnI) for the detection of myocardial injury in children with Kawasaki disease (KD) in acute stage, the levels of serum cTn I, creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactic dehydrogenase (LDH) and glutamic oxalacetic transaminase (GOT) were determined in 40 children with KD and 23 controlled children without heart disease, respectively. The results showed that the levels of serum cTn I and CK-MB in the KD group were significantly higher than those in the controlled group (P＜0.001),while no obviously differences of CK, LDH and GOT were noticed between two groups (P＞0.05). cTn I was more sensitive comparing to CK-MB for the detection of myocardial injury (P＜0.05). It is concluded that the determination of cTn I and CK-MB will be available for the diagnosis of myocardial injury in children with KD in acute stage, and the determination of cTn I is more sensitivity and specificity comparing to CK-MB.

Objective To investigate the effects of Thomas solution in combination with nitroglycerine of different concentrations on rat cardiac preservation for 8 h. Methods Thirty Wistar rats were selected,and Langendorff heart perfusion models were established.Rats were randomly divided into Thomas solution group,Thomas solution+4?10-6 mol/L nitroglycerine group and Thomas solution+4?10-5 mol/L nitroglycerine group(n=10).After hypothermic preservation(4 ℃)for 8 h,the cardiac function of each group was determined.Tissues of left ventricular wall were obtained,and changes of myocardial ultrastructure were observed by electron microscopy. Results Compared with Thomas solution group,the cardiac function was significantly improved and the myocardial ultrastructure injury was less severe in Thomas solution+4?10-5 mol/L nitroglycerine group after hypothermic preservation(4 ℃)for 8 h,while there was no significant difference in myocardial ultrastructure injury and cardiac function between Thomas solution group and Thomas solution+4?10-6 mol/L nitroglycerine group. Conclusion Thomas solution in combination with 4?10-5 mol/L nitroglycerine can significantly improve the preservation effects for isolated hearts in rats.
