OBJECTIVETo observe the efficacy of ultrasonic conductometric acupoint penetration of Wenhua Zhitong Recipe (WZR) in treating adenomyosis.

METHODSTotally 40 adenomyosis patients with Shen-deficiency blood stasis syndrome were randomly assigned to the treatment group and the control group, 20 in each group. Patients in the treatment group received ultrasonic conductometric acupoint penetration of WZR from the 2nd day before menstruation to the end of menstruation, while those in the control group took WZR. All patients received 3 consecutive menstrual cycles. Endometrial contents of cyclooxygenase-2 (COX-2) and oxytocin receptor (OTR) were determined using SP immunohistochemical staining method before and after treatment. Clinical effect, efficacy of Chinese medical syndrome, changes of uterus volume, and contents of carbohydrate antigen 125 (CA125) were observed before and after treatment.

RESULTSThere was no statistical difference in the total clinical effect between the two groups (P = 0.357). Efficacies for relieving abdominal pain and lumbar soreness during menstruation were better in the treatment group than in the control group (P < 0.05). Uterus volume, endometrial levels and integrals of COX-2 and OTR decreased in the two groups after treatment (P < 0.05, P < 0.01).

CONCLUSIONUltrasonic conductometric acupoint penetration of WZR and oral administration of WZR both could effectively improve adenomyosis patients' symptoms such as Shen deficiency, and blood stasis, reduce the foci of uterus, and relieve the pain.

Objective Multicystic renal cell carcinoma(MCRCC)appears to be a distinct subtype of renal cell carcinoma with characteristic gross and microscopic features.To explore the clinical and pathological features of MCRCC in order to find out its difference from renal clear cell carcinoma undergoing cystic change(RCCCC),and to propose prognosis criteria for therapeutic modalities.Methods From 1999 to 2003 32 patients were identified to have renal carcinoma,and they received radical or partial nephrectomy in the authors' institution.The pathological diagnosis was either MCRCC(n=21)or renal cell carcinoma associated with features of cystic changes(n=11).All specimens were reviewed histologically by two independent pathologists.The clinicopathologic and follow-up prognosis data on MCRCC and RCCCC were collected for study.Results 21 patients with MCRCC were 17 men and 4 women.The mean age at the time of surgery was 49 years(range 37 to 67 years).15 MCRCC patients with follow-up data were still alive with a mean follow-up time of 61 months(ranged 31 to 73)and no evidence of recurrence and metastasis was discovered.The mean survival time for 7 of the 11 patients with RCC was 32 months(ranged 18 to 63).There was significant difference in survival time between the two groups(P

Objective To study the pathological features and clinical significance of sarcomatoid change of renal cell carcinoma. Methods The specimens of 16 cases of sarcomatoid renal cell carcinoma admitted to our hospital were reviewed, and stress of observation was put on the the morphology and the number of the sarcomatoid components, and then their relation with clinical course, staging, and prognosis was retrospectively analyzed. Results Among the 16 cases of renal cell carcinoma with sarcomatoid transformation, 9 cases were conventional clear cell carcinoma, 3 cases were papillary renal cell carcinoma, 2 cases were chromophobic cell carcinoma, and 2 cases were collecting tubule carcinoma. In 9 cases the sarcomatoid elements were over 50% of total tumor area, while in the other 7 cases the sarcomatoid elements were less than 50%. The TNM stage among the 9 cases with more than 50% sarcomatoid elements were T2 (1/9), T3 and T4 (8/9). The TNM stage among the 7 with less than 50% sarcomatoid elements were T2 (4/7), T3 and T4 (3/7). The sarcomatoid area resembled malignant fibrous histiocytoma or fibrosarcoma. The average survival period of the patients was 19 months (8-154). Cases with over 50% sarcomatoid elements survived for 14 months in average, while the cases with less than 50% sarcomatoid area survived for 27 months in average. The difference was significant (P

Objective To explore the relationship between PIAS3 expression and the degree of malignancy of meningiomas.Methods 72 cases of different degree of malignant meningioma and 13 cases of surgical specimens of normal brain tissue were extracted the total RNA,and detected the levels of PIAS3 in different degree of meningioma and normal brain tissue through comparative control study by using real-time fluorescence quantitative PCR.Results PIAS3 was low expressed in normal brain tissue,however,high expressed in the human brain meningioma with significant differences(P＜0.01).There were also significant differences found in expression level of PIAS3 between meningiomas grade I and Ⅱ,or Ⅲ level(P＜0.05),but the differences between meningiomas grade Ⅱ and Ⅲ were not obvious(P＞0.05).And PIAS3 expression was not related with the depth of infiltration in invasive meningiomas(P＞0.05).Conclusion PIAS3 was overexpression in meningiomas,and was be closely related to the occurrence and development of meningiomas.

Objective To investigate the histological features of papillary renal cell carcinoma, and to explore the relationship between nuclear grading and prognosis. Methods The pathological slides and clinical data of 13 cases of papillary renal cell carcinoma were reviewed. The pathological features were scrutinized and nuclear grading was conducted according to Fuhrman grading system. Immunohistochemical staining for CK7, EMA, and vimentin was also respectively done. The correlation between nuclear grade and prognosis was analysed. Results The age range of the patients was from 35 to 67 (average 53) years. 10 were male and 3 were female. Most of the tumors were located in the upper pole (5cases) or lower pole (5cases). Three were located in the middle part of the kidney, with some inclination to either pole. All the tumors were well circumscribed with a size ranged from 2cm to 6.3cm (average 3.5cm) in diameter. Hemorrage and cystic change were obviously seen in large tumors. Microscopically, the tumors were composed of papillary or tubular structures, with hemorrhage, foamy macrophages and cystic change as prominent features. 6 cases were multifocal. Fuhrman nuclear grade Ⅰ or Ⅱ was made in 6 cases, and Ⅲ or Ⅳ in 7 cases. All the tumors were positive for CK7, EMA and vimentin. The patients were followed up for 28 to 102 months (average 52 months). 3 patients died of tumor recurrence or metastasis after the operation at 36, 41 and 50 months, respectively, while others survived without tumor up to now. The three dead patients were graded Ⅲ or Ⅳ by Fuhrman nuclear grading system. Conclusion Papillary renal cell carcinoma was different from other renal carcinoma variants in that they, usually have a better prognosis.
