Ductal carcinoma in situ belongs to the early stage of breast cancer.The treatment of ductal carcinoma in situ is similar with that of the breast cancer.Because of the low mortality rate in patients with ductal carcinoma in situ,there was an excessive treatment in the treatment of ductal carcinoma in situ.So the key to the treatment of ductal carcinoma in situ was to improve the quality of life.The present study shows that the effect of conserving surgery with radiotherapy is same with mastectomy's in the treatment of breast ductal carcinoma in situ.Sentinel lymph node biopsy can also be used to evaluate the patient's axillary status.For patients with ductal carcinoma in situ with breast conserving surgery,radiotherapy and endocrine therapy can reduce the recurrence rate of ipsilateral breast cancer.Radiotherapy and endocrine therapy have also become the standard treatment for ductal carcinoma in situ.

Objective:This study aimed to investigate the role of mitochondrial fusion protein 2 (Mfn2) in chronic renal injury caused by cyclosporine A (CSA) and the possible mechanism.Methods:The model of chronic CSA nephropathy was established in rats. The rats were divided into solvent control group, CSA model group and normal control group. Serum creatinine and urinary protein levels were detected. The tubulointerstitial injury was observed by light microscopy. The changes of mitochondrial structure were observed by electron microscope, and the expression of Mfn2 was detected by Western blot.Results:The levels of serum creatinine and urinary protein in CSA model group at 2 and 4 weeks were significantly higher than those in control group and solvent group ( P<0.05). In CSA model group, tubulointerstitial injury was obvious, mitochondria swelling and deformation were found in tubular epithelial cells, and ridge disappeared. Compared with normal control group and solvent control group, the expression of Mfn2 in CSA model group was significantly decreased at 2 and 4 weeks ( P<0.05), and the expression of Mfn2 in CSA model group at 4 weeks was further decreased compared with 2 weeks ( P<0.05). Conclusions:Mfn2 may play an important role in the injury of tubular epithelial cells caused by cyclosporine.

Parkinson′s disease(PD),the second neurodegenerative disease in the world,is characterized by a combination of motor symptoms(rest tremor,bradykinesia,rigidity,postural instability,stooped posture and freezing of gait)and non-motor symp?toms(including psychiatric and cognitive disorders). The core neuropathological features of PD are the loss of dopaminergic neurons in the substantia nigra and the deposition of iron and cytoplasmic protein aggregates(Lewy bodies)inside neurons. Currently,clinical treatment for PD is symptomatic and there is no effective treatment to restore neuronal degeneration. In the PD therapy ,medication re?mains dominant. Anti-PD drugs are mainly based on the critical signal pathways or some specific targets which play a key role in the pathogenesis of PD to relieve the symptoms of PD. Research and development in novel drugs to prevent or treat PD have been a crucial subject,and some novel candidates are under development. In this paper,we summarize and analyze the anti-PD drugs,and make a brief discussion about its pharmacological targets.

Objective To explore the therapeutic value of hemoperfusion combined with daytime high capacity hemofiltration in the treatment of severe acute pancreatitis.Methods The clinical data of 25 patients with severe acute pancreatitis treated by hemoperfusion combined with daytime high capacity hemofiltration(the observation group) were retrospectively analyzed,and compared with 30 severe acute pancreatitis patients without blood purification treatment(the control group).Results After the treatment,the biochemical indicator of the observation group was improved obviously compared with pre-treatment.Of the observation group,the hospital slaying time was shorter [(21.6±12.3) d vs(30.8±15.6) d],and the cure rate was higher(72％ vs 40％),and the death rate was lower (16％ vs 30％),compared with the control group(all P ＜ 0.05),but the treatment costs had no difference between the two groups.Conclusion Patients with severe acute pancreatitis on the basis of conventional treatment should conduct as early as possible hemoperfusion combined with daytime high capacity hemofiltration,and it could improve the success rate of the rescue and shorthen the length of hospital stay,and its curative effect was accurate.

Objective: To evaluate the clinical efficacy of 125I seed implantation combined with chemotherapy in the treatment of non-small cell lung carcinoma (NSCLC) and its complications. Methods: Combined treatment group (n = 42) received CT-guided interstitial 125I seed implantation (PD = 8-10 Gy/h), and three days later they were given TAX + DDP intravenous chemotherapy. Control group (n = 46) only received TAX + DDP chemotherapy. The dosage was selected based on the same reference standard as the treatment group. The therapeutic efficacy was observed two months later. The life quality of patients was evaluated by using EORTC QLQ-C30 table. Results: Both the technical success rate and follow-up rate were all 100%. In combined treatment group 4 patients achieved complete response (CR, 9.5%), 14 patients had partial response (PR, 33.3%), 20 patients with stable disease (SD, 47.6%) and 4 patients with progressed disease (PD, 9.5%). The total response rate (CR + PR) was 42.9%. In control group 1 patient achieved complete response (2.2%), 8 patients had partial response (17.4%), 22 patients with stable disease (47.8%) and 15 patients with progressed disease (32.6%). The total response rate (CR + PR) was 19.6%. The total response rate of the treatment group was significantly higher than control group. Conclusion: 125I seed implantation is synergistic with chemotherapy which is beneficial in reducing tumor load in a short period and increased the short β2-MG term therapeutic efficacy for NSCLC.

In light of modern management theories and the actual situation in the hospital, a post and performance based hospital compensation system was designed. The chief features of the design include: ① Compensation consists mainly of post salary and performance salary while giving expression to the principle of stability and gradual transition, with the fixed part (accounting for about 60%) of the original file salary being retained; ②Post salaries fall under a hospital wide unified grade compensation framework, with grade evaluations based on a hospital wide unified system of indexes and weight, and they go up or down within the salary width each year according to the results of performance assessment; ③ Performance salaries are closely linked with post grades and performance assessment, with a hospital wide unified model of post and performance contracts being the basis for assessment; ④ The entire compensation design is based on scientific and standard post surveys, post appraisals and post specifications.

ObjeCtive To investigate the value of protein biochip in the diagnosis of Lyme borreliosis. Methods The serum IgM and IgG antibodies against flagellin were detected by flagellin coated-and N-hydroxysuccinimide (NHS) modified-biochips in 82 patients with neuroborreliosis (NB),35 patients with erythema migrans (EM) and 44 normal controls.The results were compared with those from enzyme-linked immunosorbent assays (ELISA) and Western blot.Results The levels of both IgM and IgG antibodies were significantly higher in the NB patients than those in the normal controls (P
