OBJECTIVE:To select the optimum watering extraction process of yangyinqingwei oral liquid. METHODS: Influence of extraction time upon the extraction of volatile oil was observed; The orthogonal design was adopted to observe the extraction process of weight of the extracts and the content of paeoniflorin. RESULTS & CONCLUSIONS:The optimum watering extraction process of yangyinqingwei oral liquid was that medicinal materials were dipped for 30 minutes before decoction,then the extraction of volatile oil in saposhnikovia divaricata and pogostemon cablinlasted for 2 hours, next the residue of drugs and the other drugs were decocted together, and finally water of 8 times as much as the drugs were added and the mixture was extracted 3 times, with 1.5 hours for each time.

Objective To investigate the clinicopathologic and immunohistochemicalcharacteristics of primary squamous cell carcinoma of the breast(PSCCB). Methods Sixteen patients with primary squamous cell carcinoma of the breast were retrospectively reviewed. Twelve cases with a follow-up information were evaluated for ER, PR, C-erbB-2, HCK, Ki-67 expression. Results PSCCB is a very rare neoplasm,constituting 0.8 % of all breast carcinoma over 28 years(1981-2008) in our hospital. The patients age varied from 25 to 72, median age is 49 years old. All patients received operative treatment. Seven patients had metastatic disease in axillary lymph nodes. Three patients died from metastases and tumour recurrence.Tumors were usually ER-negative, but most cases showed high molecular cytokeratin (HCK) expression.Conclusion In terms of the clinical feature, there were no differences between the PSCCB and the other breast cancer. PSCCB could be confirmed by pathology. The prognosis is in controversial. Standard therapy should be studied and recommended in future.

OBJECTIVE:To prepare the compound chlorhexidine acetate ear drops for treating anaerobic and aerobic infections of antrum auris METHODS:The compound chlorhexidine acetate ear drops was prepared with mixed solvent of glycerin,alcohol and distilled water The contents of two main ingredients were determined by dual-wavelength isobestic point spectrophotometry and the stability of preparation was examined RESULTS:The average recovery of metronidazole was 99 34%(RSD=0 57%,n=6) and that of chlorhexidine acetate was 101 17%(RSD=0 88%,n=6) CONCLUSION:The new preparation is rational in formula,simple in quality control and good in stability and has good prospects in development

Objective To test intraoperative radiotherapy with mobile photon beam using the INTRABEAM system ( Germany) , and to analyze the dosimetric characteristics of low?energy photon beam using X?ray source and spherical applicators and explore its potential limitations in clinical application. Methods A special water phantom, a parallel?plate ionization chamber, and an electrometer were used to measure the depth dose rates and isotropy of dose distribution in x/y plane of X?ray source and different spherical applicators in the INTRABEAM system. Those data were then compared with the system data. Results For the X?ray source, the deviation of observed depth dose rate and isotropy in the x/y plane from the system data were-2.16%± 1. 36% and-1.9%~ 2. 1%, respectively. For applicators with different diameters, the deviation of observed depth dose rate, transfer coefficient, and isotropy in x/y plane from the system data were-10.0%~2. 3%,-8.9%~4. 2%, and-1.6%~2. 6%, respectively. Surface dose rate and dose gradient became larger with the decrease in the diameter of the spherical applicator. The measurement of depth dose rate and isotropy of X?ray source and spherical applicators showed good repeatability. The influencing factors for measurement accuracy included the positioning error of ionization chamber, energy response, noise current, and correction factor f ’ ( R ) . Conclusions This study reveals the dosimetric characteristics of the INTRABEAM system, verifies the accuracy of the system data, and obtains the data for clinical application and routine quality assurance. However, large dose gradient and small therapeutic range may limit its wide clinical application.
