The objective of this work was to investigate the effect of six individual strains of fungi on the reduction of gossypol levels and nutritional value during solid substrate fermentation of cottonseed meal (CSM). Six groups of disinfected CSM substrate were incubated for 48 h after inoculation with either of the fungi C. capsuligena ZD-1, C. tropicalis ZD-3, S. cerevisae ZD-5, A. terricola ZD-6, A. oryzae ZD-7, or A. niger ZD-8. One not inoculated group (substrate) was used as a control. Levels of initial and final free gossypol (FG), crude protein (CP), amino acids (AA) and in vitro digestibility were assayed. The experiment was done in triplicate. The experimental results indicated that microbial fermentation could greatly decrease (P<0.05) FG levels in CSM. The detoxification efficiency differed between the species of microorganisms applied. From the perspective of reducing CSM potential toxicity, C. tropicalis ZD-3 was most successful followed by S. cerevisae ZD-5 and A. niger ZD8. They could reduce FG levels of CSM to 29.8, 63.07 and 81.50 mg/kg based on DM (dry matter), respectively, and their detoxification rate were 94.57%, 88.51% and 85.16%, respectively. If crude protein, amino acids content and their in vitro digestibility were also taken into account, A. niger ZD-8 may be the best choice. The CP content of CSM substrate fermented by C. tropicalis ZD-3 and A. niger ZD-8 were improved by 10.76% and 22.24%; the TAA (total amino acids) contents were increased by 7.06% and 11.46%, and the EAA (essential amino acids) were raised by 7.77% and 12.64%, respectively. Especially, the levels of methionine, lysine and threonine were improved greatly (P<0.05). The in vitro CP digestibility of CSM fermented by C. tropicalis ZD-3 and A. niger ZD-8 was improved by 13.42% and 18.22%, the TAA were increased by 17.75% and 22.88%, and the EAA by 16.61% and 21.01%, respectively. In addition, the in vitro digestibility of methionine, lysine and threonine was also improved greatly (P<0.05).

By a orthogonal experiment, the influence of different ratio of phosphorus and potassium fertilizers on imperatorin, isoimperatorin and psoralen contents and yield of Glehnia littoralis were studied. The results showed that root dry weight and the yield of G. littoralis increased when reasonably applied phosphorus fertilizer combined with potassium fertilizer within a certain range. And the influence of phosphorus fertilizer was greater than that of potassium fertilizer. The optimal value of root dry weight and yield achieved at both P2O5 360 kg x hm(-2), K2O 270 kg x hm(-2) and P2O5 360 kg x hm(-2), K2O 180 kg x hm(-2). The effects of different phosphorus and potassium treatments on the content of imperatorin, isoimperatorin and psoralen in G. littoralis were determined, which shows that the content increased with the moderate increase of phosphorus and potassium. And the effects of phosphorus fertilizer were more significantly. The isoimperatorin content achieved the largest value at P2O5 360 kg x hm(-2), K2O 270 kg x hm(-2), also a larger content of imperatorin and psoralen. The imperatorin content is the largest when applied P2O5 360 kg x hm(-2), K2O 180 kg x hm(-2), and the isoimperatorin content was higher as well. So that the treatment of P2O5 360 kg x hm(-2), K2O 180 kg x hm(-2) are suitable for promote to the agricultural production, which could improve the quality and yield of G. littoralis.

UNLABELLEDOBJECTIVE To analyze the Chinese medicine (CM) syndrome typing features for girls with advanced puberty.

METHODSThe CM symptoms of girls with advanced puberty in the Department of CM, Children's Hospital of Fudan University from March 2008 to March 2011 were recruited and statistically analyzed. The CM syndrome typing features were summed up.

RESULTSYin deficiency induced fire hyperactivity syndrome (174 cases, accounting for 87.0%) occupied the highest ratio in the main syndrome diagnosis, followed by Gan depression transforming into fire syndrome (25 cases, accounting for 12.5%) and the endoretention of damp heat syndrome (1 case, accounting for 0.5%). The mean rank of the 3 syndrome types was sequenced from yin deficiency induced fire hyperactivity syndrome (462.87), Gan depression transforming into fire syndrome (287.22), and the endoretention of damp heat syndrome (146.91). Of them 149 (accounting for 74.5%) girls were diagnosed with both yin deficiency induced fire hyperactivity syndrome and Gan depression transforming into fire syndrome. Yin deficiency induced fire hyperactivity syndrome accompanied with Gan depression transforming into fire syndrome was the most often seen (88 cases, accounting for 44.0%), followed by Gan depression transforming into fire syndrome accompanied with yin deficiency induced fire hyperactivity syndrome (46 cases, accounting for 23.0%).

CONCLUSIONSYin deficiency induced fire hyperactivity syndrome and Gan depression transforming into fire syndrome were the leading patterns of CM syndrome typing for girls with advanced puberty. It must not neglect their combinations in clinical syndrome typing.

objective At present, most operable breast cancers are confirmed by excision biopsy during the operation. If the breast cancer was definitely diagnosed by Fine -Needle Aspiration cytology(FNA) preoperatively, the excision biopsy could be avoid. Methods We diagnosed 118 inpatients of breast mass with physical examination and FNA from September, 1995 to May, 1996. Results The sensitivity and positive predict value of FNA for diagnosing breast cancer are 95.7% and 97.1%. When the palpation and FNA are both positive, the doublepositive predict value for breast cancer is 100% in our study. It is the indication of using FNA that a breast mass was diagnosed as cancer by physical examination. We can treat a breast mass with redical operation directly without excision biopsy, if the breast mass was confirmed as breast cancer by both physical examination and FNA. Conclusion We concluded that the preoperative FNA could partially replace the excision biopsy for confirming breast cancer.

OBJECTIVETo explore clinical significance of rotational axis of distal femur on Chinese adults in total knee arthroplasty (TKA).

METHODSThere were 86 Chinese adults (106 normal knees) including 47 males (53 knees) and 39 females (53 knees), 54 knees were on left and 52 on right. The CT scan was employed in the distal femur. The scan direction was aligned to be on the plane perpendicular to the mechanical axis of the femoral. The CT images of cross sections across lateral and medial femoral epicondyle were moved to personal computer,lateral angle between anterior posterior line (APL) and surgical transepicondylar axis (STEA) (ATA),lateral angle between posterior condylar line (PCL) and APL (APA), angle between perpendicularity of APL and PCL (A-PA), posterior condylar angle (PCA), condylar twist angle (CTA), angle between clinical transepicondylar axis (CTEA) and STEA (CSA) were measured. These values were divided into different groups according to gender and side, the values of CTA, PCA, A-PA, angle PT (varus of tibia plateau), constant 3, ATA, APA and constant 90° were compared by statistically. A-PA and PCA, and CTA were analysed statistically with the liner regression, the relationship among CTEA, STEA ,PCL, APL and PLP were performed to assess by liner regression.

RESULTSATA was (89.79 ± 1.22)°, APA was (84.84 ± 1.83)°, A-PA was (5.16 ± 1.83)°, PCA was (4.80 ± 1.23)°, CTA was (8.23 ± 1.40), CSA was (3.45 ± 0.68)°. All the parameters had no differences on sex and side,but CSA had difference on male and female. There was no difference among angle PT, PCA, A-PA. There was significant difference in CAT, constant 30 and angle PT, PCA,A-PA. There was no difference between ATA and constant 90°, but there was difference between APA and constant 90°. There was relativity between PCA and CTA, and also PCA and A-PA, CTA and A-PA. There was significant relativity between STEA and CTEA, between STEA and APL, between STEA and PCL, and also between APLP, APL and PCL, but there was no significant relativity between PCL and CTEA.

CONCLUSIONTKA for Chinese, the section of femoral posterior condyle should be external 5° to obtain the optimum rotational orientation. The property is different entirely between STEA and CTEA, the rotational alignment is not performed according to parallel to the CTEA in distal femur. Among STEA, APL, PCL, the STEA is the most reliable mark ofrotational alignment of the distal femur, and the PCL is the less reliable mark.
