Chinese Journal of Primary Medicine and Pharmacy 2014;21(6):870-871
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.

6.Investigation of attentional bias to emotional-related words in first-episode depressive patients
Chinese Journal of Behavioral Medicine and Brain Science 2014;23(1):40-42
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.

Chinese Journal of Urology 2014;(7):481-485
Objective To investigate the clinical characteristics and diagnostic methods of multiple endocrine neoplasia ( MEN) 2B. Methods The clinical data collected from 4 cases with multiple endo-crine neoplasia type 2B, who had been diagnosed and treated from July .1980 to Jan.2012, were retrospec-tively analyzed.Of the 4 patients, 3 males were diagnosed at the age of 14, 24, 21, respectively, and 1 fe-male was diagnosed at age of 23.Two cases had the first diagnosis of thyroid mass during the physical exami-nation, and the adrenal tumors and hypertension were first diagnosed in other two cases , respectively.All four cases had multiple mucosal neuromata .Of whom, three cases had medullary thyroid carcinoma and pheochromocytoma , two cases had Marfan syndrome figure , and one case had pheochromocytoma and Marfan syndrome.Two cases were accompanied by paroxysmal hypertension , and the highest systolic blood pressure was over 200 mmHg (1 mmHg=0.133 KPa).Two cases of pheochromocytoma were found during follow up . Three cases had bilateral adrenal tumors .The thyroid mass was diagnosed by ultrasonography , and the pheo-chromocytoma was confirmed by ultrasonography , CT and 24-hour urine catecholamine test .Adrenalectomy and thyroidectomy were carried out during the treatment process .To clarify the RET mutation status , exons and adjacent introns from 10th to 16th of RET proto-oncogene were sequenced in two patients . Results Gene analysis of two cases confirmed the activating mutation at the sites of 918 in exon 16 of RET proto-on-cogene in which methionine was replaced by threonine ( ATG-ACG) .Among the 3 cases with medullary thy-roid carcinoma , two patients were treated by total thyroidectomy and neck lymphadenectomy , one was opera-ted by subtotal thyroidectomy .For the treatment of pheochromocytoma , adrenal tumor resection was carried out in 3 cases, but not in the other one .Patients were followed up for 2 to 15 years postoperatively , 1 case without tumor recurrence and metastasis , 2 cases with multiple metastases . Conclusions The diagnosis of multiple endocrine neoplasia type 2B mainly depends on endocrine tests , ultrasonography and CT .Surgery is the primary treatment .When pheochromocytoma coexists with other tumors , pheochromocytoma should be re-moved first .

Herald of Medicine 2001;(1):22-23
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.
