PAX2 gene encodes a nuclear transcription factor and plays a pivotal role for embryonic kidney development.It is expressed during the entire developmental process of pronephron,mesonephron and metanephron,involving in the regulation of embryonic kidney development at various fetal stages,but its expression disappeared in mature nephrons.Recently,it was found that PAX2 was re-expressed in nephropathy.Gene mutation and re-expression of PAX2 are closely related with congenital and acquired renal diseases.This paper reviews the role and significance of PAX2 expression in kidney disease from the aspects of normal expression,gene mutation and abnormal expression.

Objective To investigate the effects of clod plasma cardioplegia on the function and structure of immature myocardium. Methods Thirty-two new Zealand white rabbits of 17-26 days weighing (512 ?56) g were anesthetized and heparinized. Their hearts were excised and perfused in a Langendorff apparatus with warm (37℃) oxygenated (95%O2, 5%CO2) Krebs-Henseleit buffer(KHB) at 60 cm H2O perfusion pressure. After the isolated heart had been beating regularly for 10 min, the heart was perfused with clod (10℃) St. Thomas cardioplegic solution (group C, n = 16) or cold cardioplegic solution mixed with plasma (St. Thomas solution: plasma = 1:4) (group P, n=16). The K+ concentration of the cardioplegic solution in both groups was the same. After 30 min cardiac arrest the heart was again perfused with KHB. The following observations were made: (1) the interval from the beginning of cardioplegic solution infusion to cardiac arrest and the amount of cardioplegic solution used; (2) the duration from KHB reperfusion after 30 min cardiac arrest to the recovery of regular heart beat; (3) heat rate after recovery from cardioplegia; (4) coronary flow; (5 ) myocardial water content; (6) myocardial structural changes shown by microscopic examination. Results (1) There was no significant difference in the time needed to induce cardiac arrest and for recovery of regular heart beat from cardioplegia. (2) The heart rate was (129 ?5)beat/min in group P and (120?) beat/min in group C, the coronary flow was (5.10?0.20) ml?L-1 in group P and (3 50? 0.50) mi ?L -1 in group C, the differences were statistically significant (P

Objective To evaluate the curative effect of laparoscopic Palomo operation compared with open inguinal varicocelectomy in children with varicocele, and testis development after treatment. Methods Data of 63 boys with varicocele were reviewed. The control group(n = 29) was underwent open inguinal varicocelectomy,the lap-aroscopy group(n =34) was underwent laparoscopic Palomo operation. The operation time,hospital stay,recurrence rate,and complications rate were compared between two groups. The boys in larparoscopy group were examined the diameter of spermatic vein and testicular volume before and after operation by ultrasound. All data were analyzed by SPSS 13.0 software. Results The hospital stays and recurrence rates and complications rates were significantly different between two groups (P < 0.05 ) , but the operation time in two groups had no statisticd difference (P > 0. 05 ). The diameters of spermatic vein in larparoscopy group were decreased significantly after operation (P < 0.01). The blood supply for testis didnt decrease after operation,the operative lateral testicular volume grew faster than the contra lateral,and reached almost the same volume. Conclusions Laparoscopic Paloma varicoelectomy was safe and simple, brings a better effect for children with varicocele than open inguinal varicocelectomy does. The operative lateral testis would a postoperative compensatory growth,no testis atrophy or hypogonadism occurs.

Chinese Journal of Postgraduates of Medicine 2008;31(z1):38-41
Objective To evaluate the recovery and hemedynamics of total intravenous anaesthesia (TIVA) with propofol and remifentanil. Methods Thirty ASA Ⅰ - Ⅱ patients undergoing hperoscopic oper-ation were randomly divided into the TIVA group(group A,n=15) and the combined intravenous with inhala-tion anaesthesia greup(group B,n=15). Anaesthesia was induced in the same manner in both greups:Midazo-lam 0.05mg/kg,vecurium 0.1mg/kg,propofol 1.5mg/kg and remifentanil 1.5 μg/kg.Remifentanil was infused 2.5 μg/ml) in group A or with sevoflurane( 1.3% end-tidal) in group B to maintain anaesthesia. With termi-nation of surgery,anaesthetic delivery was discontinued simuhaneously.Bp,HR at all stages and recovery profiles were recorded. Results (1)Between before inflation and after inflation or between at the end of op-eration and the basic values in group A,there were no significant differences in Bp,HR. (2) Times from stop-ping administration of anaesthetics until full spontaneous respiration and eye opening were similar for two groups.Time for trachcal extubation was significantly less in the group A than group B. (3)The rates of post-operative nausea or vomiting were similar. Conclusion The application of TIVA with propefol and remifen-tanil is associated with better hemodynamic stability and better recovery profile as compared to the combined intravenous with inhalation anaesthesia.
