Objective To investigate the expression of phosphatidylinositol 3-kinase(PI-3K)in adipose tissue of polycystic ovary syndrome patients(PCOS),and explore molecular mechanisms of insulin resistance(IR)in PCOS.Methods Samples from patients with PCOS with IR(n=19),PCOS without IR (n=10)and controls(n=15)were collected.Serum fasting insulin(FIN)and fasting plasma glucose (FPG)were measure& Insulin resistance index was calculated using homeostasis model assessment (HOMA)to analyze the relationship between these markers and IR.Western blot technique was used to detect the PI-3K p85 subunit.Gene expression of PI-3K p85 subunit was detected by reverse transcription polymerase chain reaction(RT-PCR)method.Kinase activity was detected by immunoprecipitation,thin- layer chromatography and gamma scintillation counting.Results(1)The levels of FIN[(25.2?3.8) mU/L]and HOMA-IR(1.6?0.3)in PCOS with IR were significantly higher than those in PCOS without IR[(13.4 +3.8)mU/L,0.9?0.3]and controls[(9.5 +2.6)mU/L,0.5?0.3;all P＜0.05).(2) There was no significant difference in the protein(0.65?0.10)and gene expression(0.92?0.12)of PI-3 K p85 subunit in PCOS with IR compared with PCOS without IR(0.72?0.10,1.01?0.10)and control groups(0.73?0.14,1.00?0.12;P＞0.05).(3)PI-3K activity in PCOS with IR(81%)and PCOS without IR(89%)was significantly decreased(P＜0.01,P＜0.05)and negatively correlated with HOMA- IR(r=-0.69,P＜0.01;r=-0.62,P＜0.05).Conclusions No significant difference in the protein and gene expression of PI-3K p85 subunit in PCOS with IR is found.The decreased PI-3K activity may lead to IR of PCOS.

Objective To elucidate the possible role of p53-p21waf1 pathway for centrosome amplification in oral squamous cell carcinoma ( OSCC ) . Methods Formalin-fixed, paraffin-embedded tissues of 8 cases of normal oral epithelium tissues and 27 cases of OSCC tissues were examined for the expression of p21waf1 and mutated p53 proteins by flowcytometry and immunohistochemistry, and centrosome status was investigated by indirect immunofluorescence double staining with antibodies to centrosome protein gamma-tubulin and cytokeratin. The correlation between p21waf1, p53 and centrosome amplification in OSCC was statistically analyzed by SPSS 12.0. Results All normal oral epithelium tissues showed normal centrosomes( 1-2 centrosomes per cell) in epithelium cells, while 21 out of 27 cases(78%) of OSCC showed the evidence of centrosome amplification characterized by supernumerary centrosomes (＞2 centrosomes per cell) in a fraction of tumor cells. The quantity of p21waf1 protein was lower in OSCC with centrosome amplification [(0. 878±0. 081 )] than that in OSCC without centrosome amplification [ (0. 952±0. 018 ) ,t =3.838,P<0.01] , and negative correlations were found between the quantity of p21waf1 protein and the degree of centrosome amplification ( r = - 0.472, P＜0. 05) , as well as the positive staining of p53 ( r =-0.491 ,P＜0. 01). Conclusions p53-p21waf1 pathway might involve in centrosome duplication cycle in OSCC. Down-regulated p21waf1 protein, via p53 transactivation-dependent mechanism, was likely a contributing factor towards centrosome amplification in OSCC.

Objective:To investigate the therapeutic efficacy of double-J catheter in treatment of renal tuberculosis(TB)and in rescuing the structure and function of the kidney.Methods:Thirty-four patients with renal TB(22 combined with single side hydronephrosis)were divided into 2 groups randomly.Group A were treated with antituberculous therapy and group B with antituberculous therapy combined with pre-treatment with double-J catheter.All 34 patients were followed up for 3 months and were re-examined.Results:The results of B ultrasound,intravenous urogram(IVU),CT and isotope nephrogram were comparable between the 2 groups before treatment,and the results were significantly different between the two groups after 3 months'drug treatment(P

OBJECTIVETo present one cases of the use of balloon catheter in surgical treatment of renal angiomyolipoma involving the renal vein and vena cava as a tumor thrombus and review literatures.

METHODSAbdominal ultrasound and CT and MRI demonstrated a large right renal mass with tumor thrombus in the inferior vena cava. Right nephrectomy and en-bloc removal of the intra caval tumor thrombus were performed. A balloon catheter was used to block vena cava under the level of liver vena during the operation.

RESULTSThe pathological diagnosis was angiomyolipoma. The length of the tumor thrombus was 6.5 cm. The patient recovered well 1 year after surgery.

CONCLUSIONRenal angiomyolipoma with a tumor thrombus should be paid more attention.

OBJECTIVETo analyze the clinical characteristics of 2 microm continuous wave laser vaporization resection for the treatment of bladder tumors.

METHODSA total of 56 patients with 68 bladder tumors underwent 2 microm laser vaporization resection via a transurethral cystoscope under caudal anesthesia. In the operation, the wall of the urinary bladder was vaporized and cut, the muscular layers were removed, and then the specimens were sent for pathological inspection separately. The following variables were recorded: operation time, blood loss, complications during and after the operation, pathology staging of the tumors, and follow-up visit time.

RESULTSAll patients endured the operation. The mean surgery time was 8.8 +/- 3.3 minutes (range, 4 to 15 minutes). Blood loss was minimal, no patient experienced an obturator nerve reflection, or a hemorrhage after the operation. The pathology staging of the tumors were as follows: 40 cases (total 47 tumors) were T1 stage; 16 cases (total 21 tumors) were T2 stage. The follow-up periods were between 12 to 17 months, and the mean period was 14.5 months. Tumor recurrences were found in 3 cases, and one patients suffered two recurrences, the total recurrence rate was 5.3%. There was no primary recurrence.

CONCLUSIONSThe 2 microm continuous wave laser is a new, safe and efficacious method for the treatment of bladder tumors. Because the 2 microm laser can vaporize and cut the muscular layers of the bladder finely, it can not only treat superficial bladder tumors efficiently, but also treat some types of invasive tumors of the bladder.
