OBJECTIVETo investigate the effects of prostate stromal cells from different zones of normal prostate tissue on the growth of prostate cancer cells and their action mechanisms.
METHODSWe extracted stromal cells in the fresh normal prostatic tissue derived from the peripheral zone (PZ) or transitional zone (TZ), amplified them in vitro, and used the supernatants of the cells as conditioned media to culture hormone-resistant prostate cancer DU145 cells. We measured the growth curve of the tumor cells using the CCK8 method, determined the number and viability of the cells by trypan blue staining, evaluated their invasiveness by scratch test, and detected the effects of the stromal cells on the key enzymes in the glycolysis of the tumor cells by Western blot.
RESULTSThe conditioned medium with the PZ-derived stromal cells promoted, while that with the TZ-derived stromal cells inhibited the growth of the tumor cells. The former significantly increased, while the latter markedly decreased the expressions of the key enzymes hexokinase 2 (HK-2), pyruvate kinase 2 (PKM-2), lactate dehydrogenase (LDHA), and pyruvate dehydrogenase (PDH) in the glycolysis of the tumor cells.
CONCLUSIONProstate stromal cells from different zones exert different influences on the growth of tumor cells, which may be associated with their different effects on the glycolysis of tumor cells.

Objective To explore the effect of the transtheoretical model of health behavior change on initial insulin injection in elderly patients with type 2 diabetes mellitus. Methods Thirty elderly patients with type 2 diabetes, receiving traditional training of insulin injection , were recruited as control group ( n = 30 ) between December 2013 and March 2014 . Another 30 elderly patients with type 2 diabetes, who received an education program based on the transtheoretical model of health behavior change for insulin injection training ( 30 minutes for each time and 4 times in total ) , were recruited as experiment group ( n=30 ) between April 2014 and July 2014. The knowledge of insulin injection and the operational skills in the two groups were compared between the two groups. Result Both the knowledge and operational skills at insulin injection in the experiment group were significantly better than those in the control group (P<0.01). Conclusion The transtheoretical model of health behavior change can be significant for improving the operational skills at insulin injection and therefore it can be effective in controling of blood sugar.

Objective To investigate the effectiveness of glucocorticoids in the treatment of granulomatous lobular mastitis (GLM), and to discuss the optimal stage to add glucocorticoids during the treatment. Methods Twenty-four patients having received the core needle biopsy were involved. Ten cases with the explicit pathological diagnosis received the glucocorticoids therapy following the subtotal excision after remission. Pathological diagnoses of the rest 14 patients were undefined. For these 14 patients, simple partial excisions were given and the postoperative pathological diagnoses were presented as the GLM. Of all the 14 patients who accepted the surgical treatment firstly, 8 patients received the postoperative glucocorticoids adjuvant therapy. For the rest 6 patients, steroid hormone therapy was not used after surgery, and they were followed up postoperatively. All patients' clinical and pathological information were collected and analyzed. Results All patients were followed up for 6-36 months (average 18) by the outpatient service. Of all the 10 patients who received the glucocorticoids therapy before surgery, only 1 patient of them got the GLM recurrence. For the 8 patients who received the postoperative glucocorticoids treatment, only 1 patient got the recurrence. For the 6 patients who received simple partial excision, the recurrence of the GLM may be up to 3. There was no statistical difference between the two groups who both received the 05). But compared with the pure surgery treatment, the difference was obviously (P<0.05). Conclusions The clinical presentation and imaging performance of GLM are unspecific, so the diagnosis of the GLM is difficult. There is no consensus regarding the optimal treatment for GLM. The glucocorticoids therapy may be necessary preoperatively or postoperatively. For the patient with clear preoperative biopsy diagnosis, preoperative glucocorticoids adjuvant chemotherapy followed by the wide excision may be an effective method.
