Objective To compare the clinical efficacy of breast-conserving surgery and modified radical mastectomy for early breast cancer and their influence on quality of life.Methods 78 patients with early stage breast cancer were divided into two groups by random number table,and 39 cases in each group.The control group was given modified radical mastectomy,while the observation group was given breast-conserving surgery.The clinical efficacy,surgical conditions and quality of life scores were compared between the two groups.Results The operative time,blood loss,incision length and the average hospital stay of the observation group were (60.23 ± 5.21)min,(44.73 ± 4.22) mL,(4.72 ± 1.02) cm and (9.52 ± 0.86) d,which were significantly lower than those of the control group(t =7.88,8.32,8.89,6.42,all P ＜ 0.05).The postoperative physical factors,mental factors,psychological factors and social factors scores of the observation group were (67.44 ± 3.87),(48.64 ± 3.73),(117.34 ± 8.33)and (61.56 ± 5.32),which were significantly higher than those of the control group (t =5.43,5.87,6.29,7.11,all P ＜ 0.05).The postoperative 3-year local recurrence,distant metastasis and survival rate showed no significant differences between the two groups (x2 =1.22,1.09,1.29,all P ＞ 0.05).Conclusion Breast-conserving surgery in the treatment of early breast cancer has significant effect,and it has less trauma,less bleeding and cosmetic results,and it can be used as the preferred method for the treatment of early breast cancer,which is worth to be further applied in clinical.

OBJECTIVE:To determine the content and establish HPCE fingerprints of polysaccharides of the T.jackii seed.METHODS:The content of polysaccharides of the T.jackii seed was determined by phenol-vitriolic colorimetry and the fingerprints of polysaccharides were established by HPCE.RESULTS:The content percentage of polysaccharides in the seed of T.jackii was6.56%,with average recovery rate at98.3%and RSD at2.31(n=5).There were two kinds of polysaccharides in the seed of T.jackii.CONCLUSION:There is no significant difference with regard to the contents and components of polysacc_ harides in the T.jackii seeds from different origins.

OBJECTIVE:To study the active fraction of the seeds of Hovenia Dulcis Thunb.to treat acute alcoholism.METHODES:The seeds of Hovenia Dulcis Thunb.were divided into five parts:superitical fluid extraction(SFE)part,chloroform extraction part,ethyl acetate extraction part,n-butanol extraction part and water extraction part.The effects of the active fraction of the seeds of Hovenia Dulcis Thunb.on ebriety latency,ebriety rate,mortality,and ethanol concentration-time curve of the alcoholism mice were investigated.RESULTS:The ethyl acetate extract could prolong the ebriety latency of the mice,decrease ebriety rate and mortality of the alcoholism mice,and significantly decrease serum ethanol concentrations at 0.5,1,and 1.5h after alcohol administration(P

Cerebral infarction is caused by cerebral blood supply disturbance, and then results in cerebral hypoxic ischemic lesions, with the manifestation of neurofunction deficit. This article summarized the application of positron emission computed tomography in treat-ment of cerebral infarction.

Objective To summarize the previous work experience and loss of function in the development process of hospital modernization of sterile supply room,and discuss the model of centralized treatment and unified supply.Methods Through investigation in the clinical departments,various roles and regulations of sterile supply room were established,especially the various job responsibilities,operating procedures,disinfection and isolation system,the quality management system,testing system,equipment and apparatus management systems,traceability systems,continuous quality improvement process and goods recall system.The system had performance appraisal,workilow management and other methods to enhance the staff's self-discipline,to strengthen humanities education for sterile supply room staff,strict execution of the standards and norms of Health Ministry,to enhance the legal awareness,establish and improve the sterile supply room management systems and service system.Results Implementation of centralized treatment can effectively prevent nosocomial infection,reduce the spread of pollution to ensure medical safety,reduce staff input that help ensure the professional quality and reduce the economic costs,and promote the professional development of sterile supply.Conclusions Centralized treatment of multiplexing medical apparatus and instruments promotes the all-dimensional development of sterile supply room,which is worthy of wide application.

MicroRNA (miRNA) controls the proliferation of breast cancer cells in many ways such as cell apotosis,cell cycle and methyltransferase.Also,it controls the metastasis of breast cancer cells in many ways such as microenvironment,epithelial-mesenchymal transition and vessel formation.Large amounts of recent studies indicate that miRNAs are specifically expressed in breast cancer tissue and play important roles in proliferation,metastasis and treatment of breast cancer.

Objective: To observe the effectiveness of neltimicin sulfate in treating the infections of lower respiratory tract.　Methods: 41 cases of lower respiratory tract infections served as observation subjects (treated with netilmicin sulfate 200 mg*d-1, iv drip) while the other 30 cases as control subjects (treated with penicillin 8×109 U*d-1 and ampicillin 8.0 g*d-1, iv drip).　Results: The therapeutic effectiveness was significantly higher in the observation group than that in the control group (P＜0.01). The sensitivity tests of isolates from the sputum showed that 71.1% of the isolates were highly sensitive to netilmicin sulfate, 28.9% moderately sensitive to netilmicin sulfate. The total effectiveness rate was 97.6%.　Conclusion: Netilmicin sulfate is effective in treating the lower respiratory tract infections and causes less side effects.

Objective To explore the attentional bias in first-episode depressive patients and the correlations between the attentional bias.Methods In the beginning of the treatment,a total of 34 first-episode depressive patients in treatment-naive and demography matched 40 healthy controls completed the Chinese Emotional Stroop Task that assessed the attentional bias.Results The comparison between depressive patients and healthy controls on the reaction time of negative,neutral and positive-related words were significant ((1185.71±410.60)ms/(754.68±215.36) ms,t=5.775,P＜0.01 ; (1127.92±344.89) ms/(755.37±213.49) ms,t=5.675,P＜0.01 ;(1166.17±395.72) ms/(761.70± 194.66) ms,t=5.708,P＜0.01 respectively).Through analysis of variance,the difference of error numbers among the neutral,negative and positive-related words ((3.41 ± 2.11) times,(2.24±1.65) times,(2.97± 1.17) times) in the depressive patients were significant (F=4.197,P=0.018).The difference of error numbers between negative-related words and neutral-related words were significant through analysis of least significant difference(P＜0.01).Conclusion The results suggest that depressive patients before treatment have attentional bias in negative-related word.Attentional bias in negative-related stimuli may be one of the characteristics of cognitive function in first-episode depressive patients.
