Objective:To explore the clinic and pathologic characteristics of primary breast lymphoma(PBL) for its diagnosis and treatment.Methods: Five cases of PBL that has been diagnosed during 1998-2005 were analyzed.Results: One patient died 1 month after her final diagnosis.Tow patients have survived 4 and 3 years,respectively,after radical operation plus chemotherapy,although inguinal lymphatic metastasis was found in the later one 2 years after her operation.Another two patients have been accepting chemotherapy for 3 months after their local resection.Conclusion: PBL is diagnosed basically by methods of pathology and immunohistochemistry,and treated mainly by chemotherapy combining with other therapies.

Objective To investigate the safe model to prevent and treat complications caused by various artificial liver support system(ALSS).Methods The complications in 191 patients with severe hepatitis during the ALSS(Including plasma exchange、plasma exchange associated with continuous venovenous hemofiltration、plasma exchange associated with hemodiafiltration、plasma exchange associated with plasma absorption、molecular absorbents recycling system) treatment were observed and analyzed. Results During the treatment 287 episodes occurred and the rate of complications was 50.44%(287/569).The clinical manifestation included rash,numbness/tetany,hypotension,blood clotting in the channel,chest distress, disequilibrium syndrome,errhysis on dwell catheter,effusion on dwell catheter.75.61% of these complications was caused by plasma exchange.The rate of complications was the lowest during the treatment of plasma exchange associated with hemodiafiltration.All of these complications got better after prompt sypotomatic therapies were taken.Conclusions Although the rate of complications was high during the treatment of ALSS,all of the complications got better after prompt sypotomatic therapies were taken.This therapeusis must be performed by intensive care.It is more safe than others during the treatment of plasma exchange associated with hemodiafiltration.

0.05).Conclusions HPC has protective effect on neonatal rats with cerebral hypoxia-ischemia,but it does not have obvious effect on NGB.

Objective To investigate the trend of developmental expression of GluR2,subtype of alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid(AMPA) receptor and synaptophysin(SYP) in the rat cochlear nucleus(CN) in different developmental stages,and explore the association of GluR2 expression with the development of synapse. Methods SD rats of 2,3,4,6,8 and 10 weeks old were selected,the expression of GluR2 and SYP in CN was detected with immunofluorescence histochemical method,and the association of them was explored. Results GluR2 expression was observed in all the neurons of CN in each postnatal groups.The expression was relatively weaker in the second and third week,became denser in the fourth week,reached the peak in the sixth week and then sharply decreased to the weakest in the tenth week.The expression of GluR2 was denser at granular cell layer,while weaker at molecular layer and multipolar cell layer in the dorsal CN.SYP expression was detected in all the neurons of CN in each postnatal groups.The expression was weakest in the second week,significantly denser in the fourth week,reached the peak in the sixth week,was then sharply decreased and stably maintained. Conclusion The expressions of GluR2 and SYP in the postnatal rat CN exhit an equally age-dependent tendency.The expression of GluR2 in the CN may be associated with the the maturation and function development of the CN.The different expression and distribution of GluR2 and SYP in the rat CN of different developmental stages may be involved in the development and plasticity of auditory center.

Objective To observe the protection effects of sodium ?-aescinate(SA) on the nervous function in the rats with early spinal cord injury(SCI). Methods One hundred and twenty SD rats were randomly divided into four groups(n=30).Rats in the blank control group were performed laminectomy only,while those in the other three groups were injured at the level of Tl1 spinal segment by Allen's weight drop method(10 g ?10 cm) and immediately intraperitoneally given normal saline(5.0 mg/kg)(control group), SA(5.0 mg/kg)(SA group) and methylprednisolone(100 mg/kg)(MP group) once daily,respectively.After 8 h,24 h,96 h,7 d and 14 d,spinal cord function change of posterior limb were determined with Rivlin method.The rats were sacrificed and the injured segments were resected for pathological analysis. Results As time prolonged,the rehabilitation of spinal cord function with various degree could be observed in each group.Function rehabilitation was found among the rats in the control group,SA group and MP group 96 h after injury,and more rehabilitation was gained later in the latter two groups,while that was not the case in the control group.Rats in the SA and MP group gained more significant rehabilitation than those in the control group(P0.05).It was revealed by pathological analysis that no necrotic neurons was found in the blank control group,and the necrotic neurons in the SA group and MP group were significantly less than the control group at the same time points(P

Objectives To determine the effects of Matrine (Ma) on signal transducers and activators of transcription (STAT) 1, 3, connective tissue growth factor (CTGF) and platelet -derived growth factor (PDGF) in glomerular mesangial cells (MC) induced by lipopolysaccharide (LPS), and to explore the protective mechanisms of Ma. Methods Ma were added to cultured glomerular mesangial cells which were exposed to LPS for 12, 24 and 48 hours. Real time polymerase chain reaction were used to determine STAT1, 3, CTGF, PDGF mRNA, The protein expression of STATI, 3 and p-STAT1, 3 were observed by Western blot. Results Compared with the control group, MC proliferation of the LPS group (10μg/ml) significantly increased, which were suppressed in the Ma (320 μg/ml) group (P < 0.01) at 12, 24, 48 hours. The expression of STAT1, 3, CTGF, PDGF mRNA and the levels of p-STAT1 , p-STAT3 protein was significantly increased in MC under LPS medium at 12, 24, 48 hours, which were obviously lower in Ma group than those of the LPS group, especially at 24, 48 hours. Conclusions The protective mechanisms of Matrine is considered to down-regulate the expression of STAT1, 3, CTGF and PDGF.

Objective To compare the perioperative outcomes and short-term efficacy of three-port extraperitoneal laparoscopic radical prostatectomy (ELRP) and four-port ELRP.Methods Two hundred patients who had undergone ELRP for prostate cancer by a single surgeon from November 2010 to October 2014 were retrospectively analyzed.Among them,95 cases underwent three-port ELRP and 105 cases underwent four-port ELRP.On the basis of traditional four-port ELRP,three-port ELRP was characterized by the omission of the trocar on the inner side of right anterior superior iliac spine.The mean age was 66.8 ± 15.5 years,and mean total prostate specific antigen (tPSA) was 15.3 ± 12.4 μg/L.There were no significant differences including age,body mass index,tPSA,clinical stages,acceptance of neoadjuvant hormone therapy,history of transurethral resection of the prostate,history of diabetes mellitus between the 2 groups (P ＞ 0.05).Patients in three-port ELRP group had significantly smaller prostate volume than fourport group (35.6 ± 16.7 ml versus 42.2 ± 24.7 ml,P ＜ 0.05).The clinical factors as operative time,estimated blood loss,hospital stay,drainage tube keeping days,pathological Gleason scores,pathological stages,positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates were compared between the 2 groups.Results The three-port group had significantly shorter operative time than the four-port group (81.0 ± 18.6 min versus 103.6 ±34.6 min),less estimated blood loss (102.6 ±75.8 ml versus 217.5 ± 182.9 ml),less positive surgical margin rates (13.7％ versus 27.6％).There were 9 patients having Gleason scores more than 7 in the three-port ELRP group and 29 patients in four-port ELRP group (P ＜ 0.05).There were no significant differences of hospital stay,drainage tube keeping days,pathological stages between the 2 groups (P ＞ 0.05).Eighty-three cases in the three-port ELRP group (87.4％) were followed up for 5-19 months with the median time of 11 months.Ninety-two cases in fourport ELRP group (87.6％) were followed up for 17-52 months and the median time was 27 months.There were no significant differences of biochemical recurrence rates and urinary incontinence rates between the 2 groups(P ＞ 0.05).Conclusions Compared to four-port ELRP,three-port ELRP can provide shorter operative time,less blood loss,better negative surgical margin rates,similar oncological control and recovery of postoperative continence.In experienced hands,three-port ELRP could be a feasible and effective option for localized prostate cancer.

Objective To evaluate the learning curve of three-port extraperitoneal laparoscopic radical prostatectomy(ELRP) and to minimize operative time and blood loss about this procedure.Methods From August 2013 to October 2014,the data from 95 consecutive patients,who had undergone three-port ELRP for prostate cancer,were retrospectively analyzed.The mean age was 65.9 ± 7.7 years,mean total PSA level was 15.4 ± 12.7 μg/L,and mean body mass index(BMI) was 24.8 ± 3.2 kg/m2.According to the number of procedures performed by the surgeon,all patients were classified into three chronologic groups,including group A (No.1-32),group B (No.33-64) and group C (No.65-95).There were no significant differences including age,BMI,tPSA,estimated prostate volume,clinical stages,history of neoadjuvant endocrine therapy,history of transurethral resection of the prostate (TURP) among group A,B and C (P ＞ 0.05).The operative outcomes analyzed were operative time,estimated blood loss,hospital stay,drainage tube indwelling days,pathological Gleason scores,pathological stages,positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates.Among these 95 patients,the results of the first 32 cases were compared with those of the remaining 63 cases,the first 64 with the remaining 31.Results The average operative time in 95 patients was 81.0 ± 18.6 min.The sloping learning curve for this surgeon showed that the operative time for all 95 cases was strongly correlated with additional experience (| rs | =0.612,P＜0.01).Operative time,however,was not strongly correlated with the surgeon's experience in each group of A,B and C(P ＞0.05).Group A had longer operative time than that of Group B plus C(96.4 ± 11.3 min vs 73.2 ± 16.7 min,P ＜0.01).Group A plus B had longer operative time than that of group C (87.6 ± 17.2 min vs 67.5 ± 13.8 min,P ＜ 0.01).For all cases,the estimated blood loss was strongly correlated with additional experience (| rs | =0.677,P ＜ 0.01).Estimated blood loss was strongly correlated with the accumulation of experience for the initial 32 cases(| rs | =0.619,P ＜ 0.01).However,no strong correlation was observed over the next 63 cases.Group A had more blood loss than that of Group B plus C (158.7 ± 81.3 ml vs 74.1 ± 54.4 ml,P ＜ 0.01).Group A plus B had more blood loss than that of group C (125.5 ± 71.6 ml vs 55.3 ± 61.6 ml,P ＜ 0.01).But hospital stay,drainage tube keeping days were not strongly correlated with additional experience in each group(P ＞ 0.05).There were no significant correlation between the accumulation of experience and positive surgical margin rates,biochemical recurrence rates and urinary incontinence rates.Conclusion Our experience of three-port ELRP cases appears to be favorable with decreasing tendency in operative time,estimated blood loss with experience accumulation.Exposure to 32 surgeries,operative time and estimated blood loss reduced significantly,and after 64 cases operative time and estimated blood loss further reduced.
