Object To investigate the berberine in Coptis chinensis Franch. processed with various quantity of Evodia rutaecarpa (Juss.) Benth. and the components absorbed from E. rutaecarpa. Methods Taking berberine, evodiamine and rutaecarpine as targets, HPLC method was used to determine the components of C. chinensis, E. rutaecarpa, C. chinensis processed with 10%, 20%, 30%, 40%, 50% E. rutaecarpa. Results The content of berberine in C. chinensis processed with E. rutaecarpa decreased, and that of C. chinensis processed with 20% and 30% E. rutaecarpa was higher than the rest. C. chinensis processed with E. rutaecarpa absorbed the components of E. rutaecarpa really. Conclusion The suitable quantity of E. rutaecarpa is 20% when processing for C. chinensis.

OBJECTIVETo investigate the precise locations of the blood vessels and nerves surrounding the seminal vesicles (SV) in men and provide some anatomical evidence for SV-related minimally invasive surgery.

METHODSWe observed the courses and distribution of the blood vessels and nerves surrounding SVs and obtained the data for positioning the SV neuroplexes in 20 male pelvises.

RESULTSOne branch of the neuroplexes was distributed to the SVs bilaterally with the neurovascular bundles, (2.85 ± 0.18) cm from the median sulcus of the prostate (MSP), while another branch ran through the Denonvillier fascia behind the SV, (0.81 ± 0.06) cm from the MSP. The arterial SVs (ASV) originated from the inferior vesical artery and fell into 4 types, 55% going directly to the SVs as one branch, 15% running between the SV and the ampulla of the deferent duct as another branch, 25% downward as 2 branches to the SV and between the SV and the ampulla of the deferent duct respectively, and 5% as the other ASVs. The shortest distance from the ASV through the prostatic neuroplexus to the posterior SV was (1.08 ± 0.09) cm.

CONCLUSIONIn SV resection, neuroplexus injury can be reduced with a bilateral distance of < 2.85 cm and a posterior distance of < 0.81 cm from the MSP, and so can bleeding by vascular ligation between the SV and the ampulla of the deferent duct.

A high productive poly ?-glutamic acid(?-PGA) strain PGA-N in a culture medium containing no L-glutamine was isolated from fermentation products.With the following identifications of colony mor-phology,physiological and biochemistry experiments,and genetics,the strain PGA-N was classified as a Bacillus licheniformis.According to the product environment,the base culture medium having no L-glutamine was simulated.In order to enhance the production of the strain PGA-N,the fermentation condi-tions,such as carbon source,nitrogen source,were optimized and the ?-glutamic acid production reached 5.16 g/L after getting the optimum formulation of this culture medium.PGA-N was mutagenized with com-bination of NTG and UV.A mutant PGA-N-C10 was screened which PGA production was increased from 5.16 g/L to 8.82 g/L.The study also investigated the effects of agitation speed on the cell biomass,?-PGA production and the ?-PGA molecular weight.The ?-PGA yield of PGA-N-C10 was as high as 11.00 g/L when the agitation speed was 400 r/min.

A poly-?-glutamic acid producing strain--BLN-2, was isolated from the soybean products. According to the biochemical characteristics and 16S rRNA, the strain was identified as Bacillus subtilis. Using soybeans as culture, the solid-state fermentation conditions of BLN-2 have been studied. The results showed that the optimal carbon and nitrogen sources of BLN-2 were glucose, fructose, NaNO3 and KNO3, respectively. The orthrogonal experiments showed, when the final concentration of the fructose which was added to the soybean culture was 0.5%, the glucose, NaNO3 and KNO3 final concentraion were 2.0%, the production of ?-PGA was the highest--89.05 g/kg. It is 48.42% higher than other comparable soybean medium under the same conditions.

Objective To investigate the clinical and mammographic features of plasma cell mastitis.Methods Twenty-five patients(28 lesions)with histologically confirmed plasma cell mastitis, aged from 26 to 70 years(mean age 41 years),were examined with X-ray mammography.The clinical manifestations and imaging features were retrospectively reviewed.Results No case was in lactation.The painful irregular masses,ranged from 1.3 to 8cm in size,were found in 22 patients,while 3 patients with acute episode.Recurrent episodes of breast masses were noted in 4 patients.Based on the mammographic appearances,the plasma cell mastitis were classified as the following four types:inflammation-like type (2/28),ductal ectasia type(3/28),focal infiltration type(10/28)and nodular type(13/28).The valuable radiogyaphic signs:(1)An asymmetrically increased density along the lactiferous duct with a flame-like appearance,inhomogeneous low density tubular structures and scattered stick-shape calcifications.(2) Architectural distortion and oil cysts formation in adjacent area,(3)Subareolar ductal ectasia.Conclusions The clinical and mammographic characteristics of plasma cell mastitis are critical to avoiding unnecessary surgery.Histopathological result is needed for the diagnosis in patients highly suspected of malignancy.

[Objective]To discuss the microsurgical approaches of 30 patients with tentorial meningiomas and conclude their treatment experiences.[Methods]A retrospective analysis of clinical data was performed on 30 patients underwent microsurgical approaches from July 2004 to September 201 1.The pathology of these patients was confirmed after operation.The outcome and follow-up were evaluated.[Results] The meningiomas were totally removed in 19 patients subtotally in 6,and partially in 5.All the patients received 8 months to 5 years of follow-up:no mortality or death were found;no surgical related complications were noted.[Conclusion] Appropriate approaches according to the size and site of the tumors,intraoperative protection of venous sinus,facial and acoustic nerves and brain stem are the key points to improve the therapeutical outcomes and the post-operative quality of patients with infra and supra tentorial menmingiomas.
