Objective To examine the association between baseline body mass index (BMI) and overall survival (OS) in lymph node negative breast cancer patients. Methods From Jan. 1st, 1998 to Dec. 30th, 2008, 662 patients with lymph node negative breast cancer were treated at the Breast Center of Peking University Peo-ple’s Hospital. The clinical factors such as menopause status, tumor stage, body mass index (BMI), total triglyc-eride (TG), total cholesterol (TC) and glucose (GLU) were collected. The chi-square test was used to assess the association between obese and other factors. Log-Rank test and Cox regression analysis were performed to make univariate and multivariate analysis. Results The median follow up was 82 months (ranging from 2 to 209 months). The 5-year and 10-year survival was 93% and 82%. Obesity was associated with GLU and tumor stage (χ2=5.224, P=0.031; χ2=6.007, P=0.14), whereas there was no relationship between obesity and other factors. The Log-Rank test revealed statistically significant better survival for non obesity (χ2=4.693, P=0.030), normal GLU (χ2=4.678, P=0.031) and HR positive patients (χ2=7.837, P=0.005). COX regression analysis showed that BMI (χ2=3.874, P=0.049) and HR status (χ2=6.782, P=0.030) had independent influence on overall survival of node negative breast cancer patients. Conclusion Obesity is an adverse prognostic factor for lymph node negative breast cancer patients, which may be associated with obesity-related disorders such as high blood GLU.

OBJECTIVETo investigate the technique and its therapeutic effect of synchronous correction of lip and nasal deformity in complete bilateral cleft lip.

METHODS29 patients with complete bilateral cleft lip underwent synchronous correction of lip and nasal deformity with the modified Mulliken method for Asians. The philtral flap was 6-7 mm in length, and 3-4 mm in width at the collumellar-labial junction. The distance between the peaks of cupid's bow was 4-5 mm. The bilateral edge of philtral flap was de-epithelialized and advanced to form philtrum column. The lateral lip was advanced to the medial site, and the central vermilion tubercle was constructed with the bilateral vermilion-mucosal flap. Through the alar rim incision, the displaced cartilage was dissected and repositioned to raise the nasal tip. The follow-up period was 6 months to 6 years.

RESULTSSatisfactory results were achieved in all patients. The reconstructed upper lip had invisible scar with natural philtrum and column. The vermilion had good appearance with tubercle. The length of nasal column was not decreased and depression of nasal tip and alar was greatly improved.

CONCLUSIONSOur modified Mulliken method is effective in synchronous correction of lip and nasal deformity in bilateral cleft lip.

OBJECTIVETo analyze the relationship between inorganic ingredients (Ca, P and F) concentration of plaque residues in the primary teeth and caries status, sugar exposure frequency.

METHODSSubjects were 93 of 3-5 years old children living in Beijing area. According to their caries status, they were classified into two groups: Severe early childhood caries(S-ECC) group and caries free(CF) group. Plaque samples were collected from subjects respectively. Ca, P and F concentration of plaque residues was measured by atomic absorption spectroscopy, spectrophotometer and fluoride electrode respectively. The information of daily sugar exposure frequency of children was obtained from a standardized questionnaire filled by their parents. The relationship between inorganic ingredients (Ca, P and F) concentration of plaque residues and daily sugar exposure frequency was analyzed and the relationship between inorganic ingredients (Ca, P and F) concentration of plaque residues and caries status in the S-ECC group was also analyzed.

RESULTSThe mean values for Ca, P and F concentration of plaque residues were lower in the S-ECC group, but the difference was not statistically significant (P > 0.05). The daily sugar exposure frequency in the S-ECC group was higher than that in the CF group. There were no relationships between Ca, P and F concentration of plaque residues and caries status (dmft, dmfs), sugar exposure frequency in the primary dentition.

CONCLUSIONPlaque residues from CF subjects did not contain a greater pool of calcium, inorganic phosphorus, and fluoride ions than that from S-ECC subjects.

OBJECTIVE: Although the therapeutic method of stroke is progressed very quickly in recent years, the incidence of its post-depression is up to 40%. Poststroke depression many affect neural function recovery, for which, to understand it is advantageous of improving living quality of stroke patients.DATA SOURCE: The literatures relevant to poststroke depression were looked up from China medical nuclear journals and studies at home and abroad in recent 5 years on www.google.com, Medline. The Retrieval words: stroke, depression, incidence, relevant factors.STUDY SELECTION: Totally 42 relevant papers were selected on experimental and clinical studies on poststroke depression. The original literatures of non-randomized study were excluded and those of nonblind study were not excluded.DATA EXTRACTION: Of 42 papers, 10 papers were deleted because of repetition of various degrees and 32 papers were sorted out in category and 10 of those were selected as reference.DATA SYNTHESIS: The incidence of poststroke depression is about 40%, resulting from the co-factors of society, psychology and biology.It is viewed generally that the high risk phase of depression is in a couple of year after stroke and the duration of poststroke depression is various. The severity of neural functional deficits in recovery phase is affected by poststroke depression. Moderate and severe depression may delay the recovery of neural function and poststroke depression can also result in poor recovery of daily living capacity of patients, affect patients' cognition and increase the incidence of dementia. Concerning to clinical observation, a remarkable progression has been achieved on treatment of poststroke depression.CONCLUSION: The incidence of poststroke depression is very high,associated with multiple factors. Poststroke depression influences harmfully on neural function, cognition and daily living capacity. Active intervention and treatment provide a certain action on reducing the incidence of poststroke depression.

Objective To explore the biomechanis with different bone density by the pedicle screws fixation before and after fatigue test.Thus provide biomechanical basis for the clinical work.Methods A total of 27 fresh lumbar vertebrae samples of adult sheep (L1-L5) were equally divided into three groups,such as group A of decalcified with HCL 0 h,group B of decalcified with HCL 2 h and group C of decalcified with HCL 4 h,by using the random number table method,every groups was 9 models.Four screws was performed on the L4-L5 pedicle of vertebral arch of the three groups.Three groups were performed fatigue test of 250 000 times in 4 direction (flexion,extension,left lateral bending,right lateral bending) by (300+ 105) N load.The range of motion(ROM),the axial compressive stiffness were measured and the results in every group were compared before and after fatigue test.Results After fatigue test,ROM and the axial compressive stiffness had no significant change in group A (P＞0.05),but ROM of B group and C group were both increased and the axial compressive stiffness were decreased,Significance was found with and between groups.Conclusion The stability of people who are performed pedicle screws simplly may be decrease when the spine of osteopenia.

Since 2007, a number of published population-based studies have shown that stroke epidemiology has changed. There are some differences in morbidity, mortality, risk factors and clinical prognosis of stroke between the high-income countries and the less developed countries.
