Objective To investigate the value of perfusion CT in the evaluation of neoadjuvant chemotherapy in locally advanced squamous cell carcinoma.Methods Sixty-seven patients with Ib2-IIb squamous cell carcinoma of the cervix underwent CT perfusion imaging before neoadjuvant chemotherapy to measure blood flow (BF),blood volume (BV),peak time (MTT),permeability sur-face (PMB),perfusion time to peak (TTP)and MIP(HU);and underwent routine enhancement CT after the two course of neoadju-vant chemotherapy treatment to measure tumor size,and evaluate the therapeutic effect.Results Among 67 patients,48 patents were effective (2 completely remission and 46 partial remission),and 1 9 patients were ineffective (1 5 stable and 4 progressed),with the overall response rate of 71.6%.The differences of PMB and BV value between effective and ineffective group were statistically significant before neoadjuvant chemotherapy (P <0.001).The BF,MTT,TTP value were no significant difference between effec-tive and ineffective group before neoadjuvant chemotherapy (P >0.05).The BV and PMB value were relatively higher in the patients with effective chemotherapy.Conclusion CT perfusion imaging could measure the BV and PMB value of the tumor before neoadju-vant chemotherapy to provide the basis for treatment selection.

OBJECTIVETo evaluate the clinical effectiveness of transurethral seminal vesiculoscopy (TUSV) combined with finasteride in the treatment of recurrent hemospermia.

METHODSThis study included 32 patients with recurrent hematospermia, with the disease course of 3 months to 4 years. After administration of finasteride at 5 mg/d for 2 weeks, the patients underwent TUSV for both exploration of the causes and treatment, followed by medication with finasteride at the same dose for another 2 weeks. Postoperative follow-up was conducted for observation of the outcomes and complications.

RESULTSTUSV was successfully accomplished in all the 32 cases, which revealed 16 cases of seminal vesiculitis, 10 seminal calculi, 1 seminal vesicle cyst, 2 seminal vesicle polyps, and 3 seminal vesicle abscess. The operative time was 20 to 51 (31.0 +/- 5.2) minutes. Postoperative complications included 1 case of acute epididymitis and 3 cases of breast discomfort within the first 4 weeks. No incontinence, urethral stricture, rectal injury, retrograde ejaculation, and sexual dysfunction occurred postoperatively. All the patients but 1 were followed up for 6 months to 2 years. Twenty-nine of the cases were cured, and 2 experienced recurrence.

CONCLUSIONTransurethral seminal vesiculoscopy combined with finasteride is safe and effective for the treatment of recurrent hemospermia.

Objective To investigate the diagnosis and treatment of mucinous cystadenoma and cystadenocarcinoma of the pancreas. Methods The clinical data of 23 patients with pancreatic mucinous cystadenoma or cystadenocarcinoma confirmed by pathology from May 1993 to October 2005 was retrospectively studied. Results Fifteen cases of mucinous cystadenoma, 4 cases of mucinous cystadenocarcinoma, and 4 cases of mucinous cystadenoma with malignancy were included in this data. Ultrasonography, CT, and MRI/MRCP displayed a cystic tumor in 73.7%, 68.8%, and 83.3% of all patients, respectively. The mean diameter of the tumors was 9.4 cm, and the maximum diameter of the tumors was 20 cm. Pancreaticoduodenectomy, distal pancreatectomy and splenectomy, local excision of cystadenoma and other procedures were performed according to the site of tumors. The resectable rate was 82.6%. Twenty-one patients (91.3%) were followed up. All of the 14 patients with mucinous cystadenoma were alive with the follow-up from 4 months to 11 years after operation. Two of the 4 cases of mucinous cystadenoma with malignancy were alive with the follow-up of 5 months and 4 years after operations, while the other 2 died with the survival time of 15 months and 18 months. One patient with mucinous cystadenocacinoma was alive 5 months after operation, while the other 2 died with the survival time of 7 months and 13 months. Conclusion Mucinous cystadenoma has a malignant tendency. As the mucinous cystadenocacinoma is a low malignant potential tumor, the resectable rate is high and prognosis is satisfactory. The excision of total tumor including the surrounding pancreatic tissue is the first choice of the treatment. Pancreaticoduodenectomy, distal pancreatectomy and splenectomy, and other procedures according to the site tumors is feasible.

Objective To investigate the expression of complement split product C4d and its significance in renal allograf tissue of chronic rejection in rats.Methods The healthy closed population Wister rats and SD rats were used as donator and acceptor in renal transplantation.The chronic rejection model of renal transplant in rats was established and the rats were divided into 2 groups.The rats in experimental group were given Mycophenolate mofetil(MMF)(10 mg/kg) and those of the control group were given nothing except CsA(5 mg?kg~(-1)?d~(-1)) for 10 days.At the 12th week of renal transplantation,the allograft was tested by light microscope,and the pathological changes of renal grafts and the expression of C4d in peritubular capillaries were observed.Results On the 12th week of renal transplantation,the morphology changes of chronic rejection was observed in the experimental group and obvious C4d deposition was detected in peritubular capillaries of renal allograft tissue,with significant difference compared with those of the control group(all P
