ObjectiveTo evaluate the potential prognostic factors, and to better define appropriate treatment strategies for patients with phyllodes tumor of the breast. MethodsFourteen patients treated primarily for phyllodes tumor of the breast were reviewed retrospectively.Results The median age was 35 years. According to the histologic criteria of WHO, there were 5 benign cases(36%), 5 borderline cases(36%), and 4 malignant cases(29%). Seven patients underwent local excision, 4 cases did simple mastectomy, and 3 cases did modified radical mastectomy. Follow-up was obtained for 11 cases, with an average of 19 months. One patient died from metastasis 2 years after a modified radical mastectomy. Three patients treated by local excision presented local recurrence.Conclusion The outcome of phyllodes tumor appears to be determined by the biology of the tumor rather than by treatment modality. A wide local excision, with an adequate margin of normal breast tissue is the preferred initial therapy for phyllodes tumor of the breast.

Objective To observe the effects of cyclovirobuxinum D(Cvb-D)on the myocardium cell apoptosis of myocardial ischemia rats.Methods The rats were given Cvb-D 0.55,1.1 and 2.2 mg/kg orally per day for 21 days respectively.The myocardial ischemia model was induced by isoprenaline intraperitoneal injection.Myocardium tissue was observed under light microscope and end labelling TUNEL method was used to determine the cell apoptosis.Then the average percentage of apoptosis cell was figured out to evaluate the effect of Cyb-D.Results Cvb-D obviously lightened isoprenaline-induced myocardial pathological changes such as turbulence of myocardial fiber,plasmolysis of necrotic cell,inflammatory cell infiltration of necrotic interstitial region.Cvb-D remarkably inhibited myocardium cell apoptosis of myocardial ischemia rats caused by isoprenaline.Conclusion Cvb-D has the action of ameliorating myocardium cell apoptosis caused by myocardial ischemia.

Objective To examine the therapeutic effect of Kummerowia striata (KS) on IgA nephropathy (IgAN) rats.Methods Sixty SD rats were equally randomized into 6 groups after adaptive feeding for 3 days:blank control group,model control group,tripterygium glycosides (TG) group (in the dose of 0.0165 g/kg),and high-,middle-and low-dose KS groups (in the dose of 16.0,8.0,4.0 g/kg respectively).IgAN rat model was established with bovine serum albumin (BSA),lipopolysaccharide (LPS) and carbon tetrachloride.After modeling,rats except those in blank control group received gastric gavage of corresponding drugs for 10 continuous weeks.Levels of 24-hour proteinuria and hematuria in each group were measured,serum levels of total protein (TP),serum albumin (ALB),aspartate aminotransferase (AST),and alanine aminotransferase (ALT) were tested.The pathological changes of renal tissue were observed under light microscope by HE staining.Results Water decoction of KS could significantly decrease the proteinuria and hematuria levels,and reduce renal pathological changes of IgAN model rats.However,water decoction had no effect on indicators of liver function such as TP,ALB,AST,and ALT in IgAN rats.Conclusion KS has certain therapeutic effect on IgAN model rats.

Objective To preliminarily explore the expresssion of the Hedgehog signaling pathway (HH) after different liver trauma, and provide basis for the blockaded effection of HH and the potentiality of new traditional Chinese medicine exploition. Methods After adaptive breeding for one week, a cohort of 140 male SPF Fisher 344 rats were randomly divided into Retrorsine injection (R) indicated the toxical of chemical damage of liver, partial hepatectomy (PH) indicated the acute liver trauma, retrorsine/partial hepatectomy (R/PH) for the hepatic stem cells regeneration, and normal control (N) groups. The administering of retrorsine or placebo, and PH or sham operation were performed as Gordon’s matheds. RT-PCR, real-time PCR and immunohistochemistry were performed to detect the expression of the constituents related to HH after liver damage. Results RT-PCR demonstrated that the mRNA expression of IHH, PTCH, Smo, Gli1, Gli2, Gli3 were all activated in primary liver cells after different kinds of liver damage. The results of real-time PCR analysis indicated an interaction effect existing between the treatment and the time in 3 Hedgehog-related constituents (signaling molecule IHH, indicators of the HH activation Ptc, Gli1) (all P<0.001). The protein expression of PTCH in liver tissue section was confirmed by immunohistochemistry, which differed in the duration in PH and R/PH groups. Conclusion The HH was abnormally activated during the different liver trauma. It’s maybe an important signaling pathway during the liver’s reaction after damage.

Objective To explore the association of estrogen receptor β expression with different stages and molecular subtypes of invasive breast cancer.Methods The clinicopathologic data of 446 invasive breast cancer cases was retrospectively analyzed.ERβ expression was evaluated by types and stages.Results Of all 446 invasive breast cancer cases,328 (73.5％) were ERβ positive.The ERβ positive rate was 77.9％ (240/308) and 63.8％ (88/138) in ERα + group and ERα-group,respectively.The ERβ expression in breast cancer was positively correlated with ERα (P ＜ 0.01) while it had no correlation with PR,histological grade,HER-2 and Ki-67 (P ＞ 0.05).ERβ expression was not significantly different among different age,tumor size and axillary lymph node groups(all P ＞ 0.05).A total of 418 invasive breast cancer cases were recruited for pathologic stage and NPI analysis,including 168 cases at stage Ⅰ,152 cases at stage Ⅱ and 98 cases at stage Ⅲ.ERβ expression was not significantly different among different stages of breast cancer(P =0.743).Analyzed in these 418 cases,NPI was ＜ 3.4 in 126 cases,3.4-5.4 in 207 cases and ＞ 5.4 in 85 cases.ERβ expression was not significantly different among different NPI group (P =0.644).The ERβ positive rate in Luminal A subtype,Luminal B1 subtype,Luminal B2 subtype,HER-2 subtype and TN subtype was 75.6％ (88/118),75.9％ (110/145),85.2％ (46/54),68.4％ (39/57) and 62.5％ (45/72) respectively.ERβ expression was significantly different between Luminal subtype and non-Luminal subtype (P =0.007).Conclusions ERβ was not differentially expressed among different breast cancer stages and NPI groups.ERβ was differentially expressed in different breast cancer molecular subtypes.

Objective To discuss the application of microsurgery in the treatment of male infertility.Methods From March 2007 to March 2012,there were totally 853 infertile men received microsurgical treatments in our department.Among them,344 patients with unilateral or bilateral varicocele underwent microsurgical varicocelectomy,60 underwent vasovasostomy (VV) and 192 underwent vastoepidystomy (VE)in microsurgical methods due to obstructive azoospermia.257 non-obstructive azoospermia (NOA) patients were performed microdissection of testicular sperm extraction (MD-TESE),at the same time,pathologic examination was done.Results ①For the varicocele patients,the pre-operative sperm density was (10 ±6) × 106/ml,the progressive sperm percentage was (16 ± 9)％.The post-operative density was (15 ± 8) ×106/ml,the progressive sperm percentage was (28 ± 14)％.The natural pregnant rate was 10.8％ (37/344).②In 60 patients undergone VV,the patent rate was 80.0％ (48/60),the natural pregnant rate was 35.0％ (21/60).In 192 VE patients,the patent rate was 53.1％ (102/192),the natural pregnant rate was 19.8％ (38/192).③In 257 NOA patients,the testicular volume,sperm retrieval rate of MD-TESE was significantly higher than that of conventional testicular sperm extraction (60.3％ vs.38.1％).Conclusion The microsurgery techniques in male infertility treatments could have some advantages such as explicit effects and decreased injuries.

ObjectiveTo investigate the effects of diet-induced obesity on the developmental process of testes in pubertal Sprague Dawley (SD) rats and explore the possible reversibility. MethodsSixty one-month-old male SD rats were randomly divided into a control group ( n =10) and a model group ( n =50 ), which were fed on a normal diet and a high-fat diet, respectively. After 8 weeks, all the rats in the control group and 10 rats randomly picked out from the model group were killed. The serum testosterone and estradiol levels were measured by enzymelinked inununosorbent assay. Their left testes sections were stained by HE method, and the histology was observed under optical microscope and the spermatogenic activity was evaluated by Johnsen scoring system. The remaining 40 rats in the model group were further randomly divided into 3 subgroups: continued high-fat diet subgroup ( n =13), resume normal diet subgroup (n =13), and weight-loss subgroup (n =14). The continued high-fat diet subgroup was fed by high-fat diet, while the other two subgroups were fed by normal diet. Rats in weight-loss group took normal diet with running 20 min/d. After 6 weeks, the same parameters were assessed using the same methods. ResultsAfter 8 weeks, compared with the control group, the testosterone level of the model group significantly decreased (P =0.024) and the estradiol level significantly increased ( P =0. 017). The result of HE staining showed that the spermatogenic cell layers decreased, with part of seminiferous tubule experiencing atrophy.The number of Leydig cell also decreased and lipo vacuole was seen in the interstitial tissue of testis. The Johnsen score of the model group was significantly lower than that of the control group (P =0.000). The testosterone level was significantly lower in the continued high-fat diet subgroup than that in resume normal diet subgroup ( P =0.001 ) and weight-loss subgroup ( P =0.000), and was significantly lower in resume normal diet subgroup than that in weight-loss subgroup ( P =0.001 ). The estradiol level was significantly higher in continued high-fat diet subgroup than that in resume normal diet subgroup ( P =0.001 ) and weight-loss group ( P =0.000 ), and was significantly higher in resume normal diet subgroup than that in weight-loss group ( P =0.001 ). HE staining showed that, pathological changes aggravating and worsening compared with the control group, the model group had significantly decreased seminiferous tubule cell layers, with some seminiferous tubules experiencing atrophy.The Johnsen score was significantly higher in weight-loss subgroup than that in the other two subgroups ( P =0.000and 0.001, respectively). The Johnsen score was negatively correlated with body weight ( r =- 0.962, P =0.000), and positively correhted with the serum testosterone level ( r =0.916, P =0.000 ). Conclusions High-fat diet can induce pubertal obesity in male SD rats, which is featured by testicular hypoplasia, decreased spermatogenesis, and endocrine dysfunction. Physical exercise may improve the conditions. The degree of obesity may be negatively correlated with the spermatogenic function.

Background and purpose: With the development of the means of preoperative diagnosis and treatment of breast cancer, ifne needle puncture no longer seems to be popular with the clinical use. The safety and effectiveness of fine needle aspiration as preoperative diagnosis of breast cancer are controversial. This study was aimed to investigate the application of fine needle aspiration (FNA) of breast cancer and association between FNA and recurrence and metastasis for 30 years in our hospital. Methods:A total number of 1 260 patients with breast cancer treated in Peking Union Medical College Hospital from 1975 to 2006 were reviewed in two groups for clinical characters, recurrence, and survival rate. The two groups were FNA and non-FNA. Results:The positive rate of FNA was 61.4%and the highest rate was inⅣstage (100%). StageⅡandⅢwere the major ones in FNA group (45.2%). The local recurrence (7.0%vs 6.4%), recurrence and metastasis (13.2%vs 14.0%), 5-year (82.0%vs 81.0%) and 10-year disease free survival rates (51.0%vs 64.0%) have no signiifcant difference between FNA and non-FNA groups. Conclusion:FNA is still one of the most important methods for preoperative investigation of breast cancer.
