Chinese Journal of Current Advances in General Surgery 1999;0(02):-
Objectives:To study the relationship between the expression of PS2 protein and estrogen receptor(ER) and progesterone receptor(PR) ,c-erbB2 status and prognosis in breast cancer.Methods:PS2 protein expressions in 52 cases of breast cancer were detected by immunohistochemical method.Results:The positive rate of PS2 protein was 59.6 %(31/52) in 52 patients.There was significant correlation between PS2 protein and menopausal status,ER status,PR status respectively.Tumor size,clinical stage and lymph node status were not significantly related with the expression of PS2 protein.Patients with PS2 protein positive expression had higher 5-year-survival rate than those with PS2 protein negative expression.Conclusion:PS2 protein appears to be an independent and valid prognostic factor of breast cancer,and detection of PS2 protein expression was useful for treatment of breast cancer.

Chinese Journal of Nursing 2010;45(1):39-40
This paper introduces the perioperative nursing of 83 sialolithiasis patients undergoing sialolithectomy by sialoendoscope. The key points of successful nursing care were careful preoperative psychological nursing and equipment preparation, correct and skilled intraoperative cooperation, and early postoperative health instruction. As a result, all the patients underwent the surgery succesfully and recovered well except 3 cases who needed gland removal later.

Objective To study the efficacy of complement depletion with CVF in preventing a-cute rejection after heart allotransplantation in inbred strain rats. Methods Inbred male Lewis rats were used as recipients and Brown-Norway rats as donors, and the heterotopic heart transplantation model was established. The allografts were divided into 2 groups (n=8 in each group). After infusing low-dose CVF 20?g/kg to the CVF-treated group, cardiac allograft survival time was observed on 4 rats of each group. The remaining 4 rats in each group were killed respectively at day 1,3,5 and 6, the pathological grade for acute rejection, the complement activity in serum, the deposition of C3 on tissue, and the extent of infiltration by CD3+ T cells were compared. Results The mean survival time of heart allograft was (11. 69?0. 72) days and (6. 65?0. 35) days in CVF-treated group and control group respectively (P

Objective To research the expression of mitofusin-2 (mfn2) and tumor metastasis suppressor genes (nm23)in bladder cancer cells and its correlation with clinical pathological feature. Methods Immunohistochemistry was used to measure the expression of mfn2 and nm23.Sixty-five cases of bladder cancer were sampled,which include fif-ty cases of male and fifteen cases of female. TNM stage:Forty-seven cases were in stage I;Ten cases were in stage II; Five cases were in stageⅢ; Three cases were in stageⅣ. Other fifteen cases were sampled from normal bladder or benign tumor of bladder as control . All cases were collected from department of pathology,affiliated Hospital of hebei union university. Results The positive expression rate of mfn2 in bladder cancer tissues was significantly higher than those in normal blad-der tissues and benign tumor of bladder(χ2=32.528,P<0.05);The positive expression rate of nm23 in bladder cancer tis-sues was significantly lower than those in normal bladder tissues and benign tumor of bladder (χ2=19.719,P<0.05);the high expression level of mfn2 in bladder cancer was associated with tumor differentiation and TNM stage(P<0.05),but not corre-lated with age,sex,lymph node metastasis and clinical grade. The low level of nm23 was associated with TNM stage,clinical grade and LN metastasis. Conclusion The positive expression rate of mfn2 was increased in bladder cancer. It indicated that there was a close relationship between mfn2 and the occurrence and development of bladder cancer;The expression rate of nm23 was decreased in bladder cancer,it may be a predictor for metastasis and prognosis of bladder cancer.

The quality of traditional Chinese medicines (TCMs) has been mainly evaluated based on chemical ingredients, yet recently more attentions have been paid on biological ingredients, especially for pill-based preparations. It is a key approach to establish a fast, accurate and systematic method of biological ingredient analysis for realization of modernization, industrialization and internationalization of TCMs. The biological ingredient analysis of TCM preparations could be abstracted as the identification of multiple species from a biological mixture. The metagenomic approach based on high-throughput-sequencing (HTS) and big-data-mining has been considered as one of the most effective methods for multiple species analysis of a biological mixture, which would also be helpful for the analysis of biological ingredients in TCMs. Simultaneous identification of diverse species, including the prescribed species, adulterants, toxic species, protected species and even the biological impurities introduced through production process, could be achieved by selecting appropriate DNA biomarkers, as well as applying large-scale sequence comparison and data mining. By this approach, it is prospective to offer an evaluation basis for the effectiveness, safety and legality of TCM preparations.
