Objective To evaluate the value of MSCT perfusion imaging in assessment of single renal function of hydronephrotic kidney.Methods 64-slice spiral CT perfusion was performed in 36 obstructive nephrohydrosis patients whose split renal glomerular filtration rate(GFR) was measured by SPECT renal dynamic imaging. ①The perfusion parameters of the renal cortex and renal medulla of the hydronephrotic kidney were compared with the normal kidney studied by contrast group. ②The 72 kidneys were divided into normal renal function, mild and severe renal impairment groups according to renal function. Differences between the groups respect to all the mean perfusion parameters of the renal cortex and renal medulla were assesses by ANOVA. ③Using Pearsons correlation test, the correlations between all the mean perfusion parameters of the renal cortex and renal medulla and renal GFR were examined.Results ① The time-density curves of bilateral normal renal cortex and medulla were not symmetric. The mean BF, BV, PS, PBV of renal cortex were (203. 2±44.9)ml·100 ml~(-1)·min~(-1), (27.6±3.9)ml/100 ml, (30.7±6.5)ml·100 ml~(-1)· min~(-1), (46.5±10. 9)ml/100 ml; and the mean BF, BV, PS, PBV of renal medulla were (99.9±24.1)ml·100 ml~(-1)·min~(-1) ,(18. 3±4.3)ml/100 ml, (51.8±12.1)ml · 100 ml~(-1)· min~(-1) , (21.3±3.0)ml/100 ml. The mean perfusion parameters of the cortex and medulla of obstructed kidney were lower compared to that of normal kidney. ②There were significant differences of all the perfusion parameters of the renal cortex and me-dulla between 3 groups (P<0. 05). ③The perfusion parameters of the renal cortex and medulla had positive linear correlation with GFR. The best correlation was the blood flow of the cortex of kidney. The correlation coefficient r=0.852.Conclusions64-slice spiral CT perfusion imaging can quantita-tively evaluate the haemodynamic condition and functional lesion of the kidney, classify the impaired kidney function. The perfusion parameters of the renal cortex and medulla had positive linear correlation with GFR.

Objective To compare the clinical effect of laparoscopic and open appendectomy in the treat-ment of perforated appendicitis.Methods 107 patients with perforated appendicitis were selected as the research object and were divided into two groups.The observation group(54cases)received laparoscopic appendectomy while the control group (53cases)received traditional open appendectomy.The size of incision,the amount of bleeding during operation,time of operation and hospitalization and other perioperative indexes and the incidence rate of complications were compared between the two groups.Results The operation time between the two groups had no statistical significance(t =1.286,P >0.05 ).The incision size [(2.5 ±0.3)cm],the amount of intraoperative bleeding[(10.3 ±3.4)mL]and hospitalization time[(5.4 ±0.9)d]of the observation group were better than those of (4.2 ±0.4)cm,(19.4 ±4.2)mL and (6.5 ±1.1 )d in the control group,the differences were statistically significant(t =24.901,12.329,5.666,all P <0.05).The occurrence rate of complications of the observation group was 3.4%,which was lower than 15.1% of the control group,the difference was statistically significant(χ2 =3.940, P <0.05 ).Conclusion Laparoscopic appendectomy has the advantages of less trauma,faster recovery,less complications,shorter hospitalization time,etc.And its effect is better than open appendectomy and worthy of populari-zation and application.

Objective To investigate the therapeutic mechanism of bazedoxifene, the third-generation selective ER modulator (SERM), on endometriosis lesions in a rat model. Methods Endometriosis was induced by transplanting pieces of endometrium from other syngeneic rats that were as donors onto the subcutaneous of other unmated female rats. The rats with successful ectopic implants were divided into two groups:control group (n=10) and bazedoxifene group (n=10). The macroscopic morphology, volume, histopathology of ectopic implant and rats uterine wet weight were determined before and after the treatment. Expression of proliferation cell nuclear antigen (PCNA), ER and PR in the eutopic endometrium and endometriosis lesions detected by immunohistochemistry in the two groups. Results (1) The gross morphology and histological changes of endometriosis lesions in rats after treatment: compared with the control group, it was obviously depauperated and had more less glands and blood vessels in the stroma. (2) The change of rats′weight, the volume of endometriosis lesion before and after treatment and rats uterine wet weigh after treatment respectively in the control group and the bazedoxifene group:rats′ weight were respectively before treatment: (201±17) g, (202±18) g, that were respectively after treatment: (266±16) g, (261±16) g, which showed no significant difference between two groups before and after treatment (P>0.05). The volume of ectopic implant before treatment were respectively (85±17) mm3, (85±12) mm3, and showed no significant difference between two groups;that were respectively (48±11) mm3, (24±9) mm3 afte rtreatment, which was significantly decreased compared with the control group (P<0.05). Rats uterine wet weight after treatment were respectively:(0.77±0.16) g, (0.45±0.18) g, and was significantly reduced compared with the control group (P<0.05). (3) The protein expression levels of PCNA, ER and PR in the endometriosis lesions after treatment were respectively 0.282 ± 0.044, 0.51 ± 0.06, 0.49 ± 0.05 in the control group, 0.191 ± 0.020, 0.23 ± 0.03, 0.48 ± 0.06 in the bazedoxifene group; that in eutopic endometrium were respectively 0.369 ± 0.081, 0.56 ± 0.08, 0.56 ± 0.10 in the control group, 0.211 ± 0.037, 0.27 ± 0.05, 0.54 ± 0.08 in the bazedoxifene group;the protein expression levels of PCNA and ER in endometriosis lesions and the eutopic endometrium were significantly decreased in the bazedoxifene group compared with the control group (P<0.05), but the protein levels of PR in endometriosis lesionsand and the eutopic endometrium were not significantly altered by treatment (P>0.05). Conclusion Bazedoxifene could obviously reduce the size of endometriosis lesions, the mechanism may be related with suppressing estrogen-induced proliferation, the expression of ER and direct ER antagonism by this SERM.
