Objective To compare the effects of mammaplasty, non mammaplasty and prosthesis reconstruction in the treatment of quadrant or massive mastectomy. Methods One hundred and twenty patients with segmental or quadrant mastectomy in the First People′s Hospital of Huizhou from February 2015 to December 2016 were selected for the study. The patients were divided into three groups:the mammaplasty group (48 cases),the non mammaplasty group (40 cases),and the prosthesis reconstruction group (32 cases). The patients in the mammaplasty group were treated with quadrant or massive mastectomy, patients in the non mammaplasty group were treated with chest wall fat fascia flap and the prosthesis reconstruction group was treated with the application of the skin flap of the lateral chest wall. The general operation situation of the three groups were recorded,including operation time,indwelling time of drainage tube,hospitalization time and postoperative hospitalization time. The satisfaction and complications of breast reconstruction were compared among the three groups. Results The operation time of the mammaplasty group, non mammaplasty group and prosthesis reconstruction group were (71. 5±18. 4) min,(55. 9±14. 3) min and (89. 7±21. 3) min respectively,there was significant difference among the three groups (F=31.32,P<0.01).The operation time of the mammaplasty group was longer than that of the non mammaplasty group, but less than that of the prosthetic reconstruction group, the difference was statistically significant ( P< 0. 05 ) . The hospitalization time and postoperative hospitalization time in the prosthesis reconstruction group were ( 13. 7 ± 3. 4 ) d and ( 10. 9 ± 2. 6 ) d, mammaplasty group (11. 4±2. 2) d and (8. 6±1. 9) d respectively,non mammaplasty group (11. 3±2) d and (8±1. 8) d respectively. The differences among the 3 groups were statistically significant (F=10. 20,18. 88,P <0. 01) . The postoperative hospitalization time of the prosthesis group was significantly longer than those in the other two groups ( P<0. 05) . The indwelling time of the drainage tube was close in the 3 groups. The overall satisfaction of breast reconstruction in the mammaplasty group, non mammaplasty group and the prosthesis reconstruction group were respectively ( 9. 2 ± 0. 8 ) points, ( 9. 1 ± 0. 6 ) points, ( 7. 9 ± 1. 3 ) points, and the difference was statistically significant ( F=23. 22,P<0. 01) . The satisfaction degrees of breast reconstruction in the mammaplasty group and the prosthesis reconstruction group were equal, higher than that in the non mammaplasty group,the differences were statistically significant ( P<0. 05) . The incidence of wound infection in the mammaplasty group, non mammaplasty group and prosthesis reconstruction group were 10. 4% ( 5/48 ) , 10. 0% (4/40) and 6. 3% (2/32),respectively,the difference was not statistically significant (χ2=1. 29,P=0. 08) . Conclusion In quadrant or massive mastectomy,lateral chest wall fat fascia flap has simple operation and high safety,and the restoration effect is good,which can be widely used in clinical practice.

0.05).Among the test group.the number of medium nebulization were significatly more than that in the contrast group(P0.05).Conclusions: Early continuous and administration of oxygen nebulization with 0.45%sodium chloridecan not only decrease the Visco-elasticity of sputum, but aslo sustain the stability of oxygen partial pressure in blood in the study.

The resuets of the screening of abnormal Hb among people of Hani and Yi minority nationalitios in Honghe, Yunnan were reported in this paper, It was found that the inci- dence of abnormal Hb in This area was 1.25%, By studying the types of abnormal Hb, we found that the main abnormal Hb in Hani and Yi minority nationalities was Hb E. In addi- tion, a slow-mouing Hb was found, Primary structural analysis showed that it was a ?-Chaim variant designated as Hb G-Yuanyang (?43 (CD2) Glu-Gly),. it is a new vari- ant type of abnormal Hb found and reported for the first time in Yunnan, China.

The article expounds the advantages and existing problems of TCM differentiation by signs,puts forwards the concept of “sign factor”,including sign factors of disease location and disease nature;the contents of the new system are as well provided,finally it points out the great meaning of the said system to the development of TCM.

Many PICU and NICU have been gradually established from 80's in China,and the rescueing success rate of critically ill pediatrics is increasing fast.However,to assess the severity of disease and to determine the ICU admission standards is a quite complex job.Using scoring systems to predict hospital mortality in critically ill patients can be more objectively,scientifically and effectively.There are some scoring systems widely used in the world.Hospitals in china use PCIS more and these in foreign prone to PRISM score highly in pediattic field.PCIS was made in china and it achieves great success on the side of risk adjustment and mortality prediction.But pediatrics are special,sometimes the severity of disease is not completely consistent with the prognosis and the differences among individuals cannot be ignored yet,so PCIS have unavoidable limitations.The scoring systems and clinical symptoms and signs and therapeutic effect should be combined to assess the severity of disease more accurately.Acute physiology and chronic health evaluation(APACHE),and sequential organ failure estimation score(SOFA) are rarely used in the field of pediatric applications,but both are useful tools for clinical research,if it can be introduced into the pediatric field,there may be a new breakthrough.Besides,Pediatric Risk of Mortality Score and Pediatric Risk of Mortality are not widely used in our country.

Objective To investigate the brain protection effect of cinnamon water extract on chronic cerebral ischemia rats. Methods We selected male Wistar rats to make chronic cerebral ischemia model by bilateral carotid artery ligation permanently,and the models were randomized into a model group,cinnamon high or low dose group,with 20 in each group. A control group with 20 rats was treated with sham operation. The cinnamon high and low dose groups were given cinnamon water extract 4.2g/kg and 2.1g/kg respectively by gavage in succession for 4 weeks. Y-maze test was used to test the cognitive ability of the rats. The superoxide dismutase (SOD) activity,malondialdehyde (MDA) content,and the expressions of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) were determined. Results Compared with the sham-operated group,the cognitive ability of the model group declined,the SOD activity of brain tissues decreased,and the MDA content increased. Cinnamon improved the SOD activity,reduced the MDA content,increased the NGF and BDNF expressions,and the effect of high-dose group was better than that of the low-dose group. Conclusion Cinnamon plays its role in cerebral protection through increasing the SOD activity and expression of NGF and BDNF and reducing content of MDA.

Objective To investigate the effects of hyperoxaluria on rat renal tubular epithelium intracellular calcium concentration ([Ca~(2+)]i) and cell apoptosis, and explore the protective effects of calcium antagonist-nifedipine. Methods Sixty male SD rats were randomly divided into six groups (n=10). Rats in water-drinking group were treated with deionized water, nifedipine group with deionized water and nifedipine 10 mg·kg~(-1)·d~(-1), calculi-induced group with deionized water containing 1% ethylene glycol, and three calculi-induced+nifedipine-intervening groups with deionized water containing 1% ethylene glycol plus nifedipine 3, 6 and 10 mg·kg~(-1)·d~(-1), respectively. Four weeks later, the 24 h oxaluria concentration was measured, the apoptosis index of renal tubular epithelial cells was detected with TUNEL method, and Ca~(2+) fluorescence intensity of cells of renal proximal tubules was determined by flow cytometry using Fluo-3/AM staining. Results The 24 h oxaluria concentrations in calculi-induced group and calculi-induced+nifedipine-intervening groups were higher than those in water-drinking group and nifedipine group (P＜0.01). The apoptosis index and Ca~(2+) fluorescence intensity were significantly higher in calculi-induced group than those in water-drinking group (P<0.01). The Ca~(2+) fluorescence intensity in calculi-induced+nifedipine (3, 6 and 10 mg·kg~(-1)·d~(-1))-intervening groups was 76.7%, 62.7% and 56.4% of calculi-induced group, respectively, with a significant dose-effect relationship (r=0.839, P<0.01). The apoptosis index of renal tubular epithelial cells was significantly correlated with Ca~(2+) fluorescence intensity (r=0.826, P<0.01). Conclusion Hyperoxaluria can increase apoptosis and [Ca~(2+)]i concentration of renal tubular epithelial cells in rats, and nifedipine can effectively protect renal tubular epithelial cells to resist hyperoxaluria.

BACKGROUND: At present, it is affirmed that coping style is the important mediator between stress and health both on mental and body. The coping theory is descripted as three orientations: trait view, contextual view and interaction person-environment view. The conception and classification of the coping styles still remains to be explored. OBJECTIVE: To probe into the dimensions of coping styles, the characteristics of different coping styles and the correlation between coping styles and psychological adaptation among college students.DESTGN: Questionnaire investigation.SETTING: School of Psychology, Beijing Normal University.PARTICIPANTS: Altogether 343 college students were randomly chosen from Tianjin University, Tianjin University of Commerce, Tianjin Normal University and Tianjin University of Finance and Economics. The college students, including 161 males and 182 females, were aged (19±2) years, ranging from 19 to 22 years. According to body health examniation records of them, all the college students had no serious chronic or acute illness. Written informed consents were obtained from all the college students.METHODS: The college students were measured collectively in their own classroom respectively from September to December in 1999. There were totally 16 class units. Altogether 422 copies of questionnaire files were sent out. Each copy includes Coping Styles Scales, Adolescent Psychological Adaptation Scales, and SCL-90.The questionnaires were collected once the college students completed. Copying styles were assessed with Coping Style Scale revised by Liang Baoyong, which includes 20 items. Each item gives one kind of coping strategies in daily life. For example, "To tell myself,my trouble is nothing matter When comparing with others, it is no worthy to be annoyant". The college students should be asked to answer on the 5-point Likert scale. These 20 items covered majority of coping styles which were used by adolescents. Two indexes were used as the results of psychological adaptation: one is Adolescent Psychological Adaptation Scale developed by Chen Huichang, including 20 items. Scores were collected on the 5-point Likert scale in which high scores mean better adaptation. Another result variable is the amount of SCL-90. High scores mean more symptoms with mental or physical state which stands for lower adaptation level. All the assessment data were input into Foxbase data-base, then were analyzed using factor analysis and cluster analysis in order to attain different kinds of college students coping styles. Correlation analysis was used to examine the correlation between coping style and adaptation. MAIN OUTCOME MEASURES: Coping styles of college students and correlation between different coping styles and adaptation results.RESULTS: A total of 422 copies of questionnaires were sent out, and 362 copies were drawn back, 19 copies were invalid questionnaires due to either there were missing answers or the answer had reflective tendency. At last, 343 sets of data entered the analysis procedure. ① According to factor analysis results, the main coping styles used by college students were F1 (seeking support), F2(positive thinking), F3(cognitive adjustment), F4(passive blame oneself), F5(facing reality), F6(avoidance), F7(emotional catharsis).There were three main coping styles from cluster analysis, that was, A (positive confrontation), B (passive avoidance) and C(passive catharsis).② Those who were more adaptive used A coping style more frequently, and those who had lower adaptation level used B or C coping style more frequently. But few students used C coping style. A coping style was significantly negatively correlated with mental or physical symptoms (r= -0.258,P＜ 0.01 ),but significantly positively correlated with adaptation level (r =0.467, P ＜ 0.01);But both B and C coping styles were significantly positively correlated with mental or physical symptoms (r=0.338, 0.364, P ＜ 0.01 ), B coping style was significantly negatively correlated with psychological adaptation(r =-0.140, P ＜ 0.05). It seemed that C coping style had no correlation with long-term adaptation. A and C coping styles were two dependent styles respectively. In addition, different levels of stress were significantly correlated with three styles. Few A coping styles were used under high level of stress, but more B and C coping styles did.CONCLUSION: Coping style is complex. Use of different copying styles is significantly correlated with psychological adaptation levels. But the direction of correlation is effected by the factors, such as individuals, index of results and degree of stress.
