Objective To investigate the therapeutic effect of Xiaoxuan Kangfu capsule in treating psoriasis vulgaris. Methods All patients were divided into two groups randomly (60 patients in a control group and 60 patients in a treatment group). In the control group complex Qingdai capsule was given to the patients, with 4 pills for each time and 3 times daily. While in treatment group Xiaoxuan Kangfu capsule was given to the patients with 6 pills for each time and twice daily. 30 days consisted one treatment period for both groups. The patients undertook one to three treatment period according to the patients' pathogenetic condition. The rates of recovery and improvement and were compared. Results In the treatment group, 34 patients were cured (42.5%), and the total effective rate was 87.5%; while in the control group 14 patients were cured (7.5%), and the total effective rate was 72.5%. There was statistic difference between the two groups (P＜0.05). The average heal time of the treatment group was shorter than that of the control group, showing statistic difference (P＜0.05).Conclusion Xiaoxuan Kangfu capsule showed higher recovery rate, shorter healing time and lower recurrence rate in treating psoriasis vulgaris than complex Qingdai capsule. The treatment is deserving clinical spread.

Objective To investigate the MR imaging features of chondroblastoma,and to address the correlation with findings of X-ray radiography and CT.Methods The imaging findings including MRI,X-ray radiography and CT of 16 chondroblastomas proved by surgery and pathology were analyzed and correlated with each other. Results All sixteen chondroblastomas involved the epiphyses of long bones,with varying sizes from 0.8 cm to 5.1 cm and lobulation. They were iso- and hypo-intense on T1WI and had heterogeneous signals on T2WI.They were of soft tissue density on CT,and had areas of calcifications and low density.The rims were hypointense on both T1 WI and T2 WI and showed hyperdensity on CT. The lesions were surrounded by edema of bone marrow which was hypointense on T1 WI and hyperintense on fat suppressed T2WI,while on X-Ray film and CT it was hyperdense sclerotic area.The adjacent soft tissues were swelling.Nine cases had periosteal abnormalities on MRI in which 8 of 9 periosteal abnormalities were distant from the primary lesions,and 6 of them showed hyperdense perosteal new bone on CT.Twelve cases had joint effusion on MRI and CT detected 6 of them.The lesions had heterogeneous enhancement,and there was enhancement in areas of edema within bone marrow,periosteal reaction and adjacent soft tissue.Chondroblastoma was intermediate and hyperintense on DWI,and the intermediate areas on both T1 WI and T2WI,together with areas of bone marrow edema,periosteal reaction and soft tissue swelling,were hyperintense on DWI.Conclusions The MRI,X-ray and CT can reflect the pathological changes of chondroblastoma from different aspects.The characteristics of chondroblastoma can be better appreciated by combining different imaging methods.

A case of metachronous bilateral renal pelvic carcinoma was reported. A 55-year-old women underwent left nephroureterectomy for the left renal pelvis cancer in 2011, then she was diagnosed with right renal pelvis carcinoma because of intermittent hematuria in 2014.A transurethral ureteroscopic holmium laser resection of the right renal pelvic tumor, partial right pelvis resection and nephrostomy, instillation with hydroxycamptothecin were taken sequentially to delay the dialysis for 53 months. In 2018, the patient underwent right nephroureterectomy because of recurrence of right renal pelvic carcinoma. The patient was followed up for 17 months postoperatively and there was no recurrence. In this case, patient's renal function was protected by the premise tumor control through a variety of minimally invasive and pharmaceutical therapy, which can provide a reference for the kidney-preserving treatment of high-grade renal pelvis cancer.
