Objective To evaluate the accuracy of core needle biopsy (CNB) in diagnosing breast masses and its coherence with immunohistochemical (IHC) examination results of estrogen receptor (ER), progesterone receptor (PR) and Her2 protein between pre-and post-chemotherapy in invasive breast cancer. Methods The results of 516 CNB cases from June, 2005 to April, 2008 were analyzed retrospectively. The pathological examination was performed by two pathologists independently. Results 484 cases of malignant tumor, carcinoma in situ and phyllodes tumor were found in this group with the sensitivity of 96.7%. Sixteen cases of false negative (3. 3% ) were demonstrated by surgical biopsy. The accurate rate of CNB was not influenced by the maximum diameter of masses ( P = O. 423 ). The agreement rate of IHC results of ER, PgR and Her2 between pre- and post-chemotherapy were 90. 3%, 76. 8% and 82.5%, respectively. Conclusion CNB is a useful diagnostic method with a satisfactory accuracy in any size of breast masses. Given the histological heterogeneity of invasive breast cancer and the influence of ehemotherapy, the coherence of prechemotherapy IHC for ER, PgR and Her2 is not optimal with that of post-chemotherapy.

Objective To analyze the relationships between the drinking water fluoride and bone mineral density (BMD), and serum osteocalcin (BGP) and to explore the BMD and serum BGP as significant early screening biomarkers for fluorosis especially for early bone damage in endemic fluorosis areas. Methods Wamiao (severe endemic fluorosis area, as fluoride exposed group) and Xinhuai (non endemic fluorosis area, as control group) Village were selected in 2006. One hundred and fouty-six objects were chosen from 2 villages (103 in Wamiao, 43 in Xinhuai). The sex, age, body height, body weight, drinking water fluoride in each object's household well, BMD, and serum BGP were investigated, and the dose-response relationships were analyzed between the drinking water fluoride and BMD, and serum BGP. CurveExpert 1.3 Software was used to fit the dose-response relationships between the rate of abnormal BMD, the rate of abnormal serum BGP, and the drinking water fluoride. Results The levels of drinking water fluoride in males' and females' families in fluoride exposed group were [(2.38±0.68), (2.62±0.91 )mg/L] significant higher than that in control group [(0.35±0.08), (0.36±0.07)mg/L], the difference being statistically significant(t values were 14.27 and 11.08,and P<0.01, respectively). BMD in males in fluoride exposed group [(0.78±0.07)g/cm2] was significant lower than that in control group[(0.83±0.08)g/cm2], the difference being statistically significant (t=2.37,P<0.05). Serum BGP in males and females in fluoride exposed group [(4.17±0.67), (4.11±0.57) μg/L] were significant higher than that in control group [(1.48±0.40), (1.44±0.39)μg/L], the difference being statistically significant (t values were 17.64 and 19.40, and P<0.01, respectively]. BMD in the group with drinking water fluoride≥2.92 mg/L[(0.66±0.15 )g/cm2] was significant lower than that in the group with drinking water fluoride<0.42 mg/L [(0.76±0.12)g/cm2], the difference being statistically significant (P<0.01). The levels of serum BGP in the groups with the drinking water 0.42-,2.05-, ≥.92 mg/L[(3.83±1.07), (4.22±0.72), (3.99±0.63) μg/L] were significant higher than that in the group with the drinking water<0.42 mg/L [(1.44±0.37) μg/L], the difference being statistically significant (P<0.01). The equation for the dose-response relationship between the drinking water fluoride and the rate of abnormal BMD was y=(0.284-0.058x)-1.260, r=0.999 94; and y=100.05/(1+78.62e-4.5x), r=0.999 99 for the drinking water fluoride and the rate of abnormal serum BGP. Conclusions There were significant dose-response relationships between drinking water fluoride and BMD and serum BGP. It indicated that BMD and BGP might be considered as early screening biomarkers for endemic fluorosis, especially for the bone damage.

Objective To explore the impact factors for post-thaw embryo survival rate and clinical pregnancy rate in frozen-thawed embryo transfer program. Methods The clinical data of 573 cycles of frozen-thawed embryo transfers were retrospectively analysed. Groups were divided according to the pre-freeze embryo quality, pre-freeze embryonic developmental stage, frozen-thawed embryo quality and cryopreservation technique, respectively, and post-thaw embryo survival rates and/or clinical pregnancy rates were compared among groups. Results The clinical pregnancy rate of high quality pre-freeze embryo was significantly higher than that of low quality pre-freeze embryo (31.8% vs 20.0%) (P< 0.05). There was no significant difference in the post-thaw survival rates and clinical pregnancy rates between embryos frozen at day 2 of ferrtilization and those frozen at day 3 of ferrtilization(79. 1% vs 82.9% and 25.5% vs 31.2%, respectively) (P>0.05). The clinical pregnancy rates of the transfer cycles only with fully intact embryos and with mixed embryos were significantly higher than that only with partially damaged embryos(36.7% vs 24.1% and 29.2% vs 24.1%, respectively)(P<0.05). The post-thaw survival rate and post-thaw high-quality embryo rate were significantly higher in those processed with modified cryopreservation technique than in those processed with original cryopreservation technique (82.0% vs 66.3% and 50.0% vs 27.5%, respectively)(P<0.05). Conclusion Pre-freeze embryo quality, post-thaw embryo survival rate and post-thaw embryo quality have a positive correlation to subsequent clinical pregnancy rate. Favorable cryopreservation technique may ensure the success of post-thaw embryo recovery and transfer.

Objectives:To evaluate the use of needle catheter jejunostomy for early enteral nutrition in liver transplant recipients . Methods:Five liver transplant recipients who had indication were performed with needle catheter jejunostomy before abdominal wall closure.The Flocare jejunokath was inserted on the small bowel at the point 20 cm distal to the ligament of Treitz,continued to go ahead in the wall of the bowel for a distance of about 4～5 cm,and then pierced into bowel lumen.Enteral nutrition was given through jejunostic tube at postoperative 1st day. Results:The time for placing needle catheter jejunostomy during operation was (9.2?2.3)min.The jejunostic tube was used well and pulled out from 14 to 46 days after operation.One patient occurred with jejunostic tube obstruction, and the tube was reused after treatment.No other complication occurred associated with needle catheter jejunostomy. Conclusions:Needle catheter jejunostomy may become the preferable method for early enteral nutrition in indicated liver transplant recipients.

Objective To analyze clinical characteristics of invasive Luminal subtype breast cancer.Methods The data of 162 invasive Luminal subtype breast cancer patients receiving operation in Cancer Hospital of Chinese Academy of Medical Science from January 1 st to September 30th in 2002,were collected and the clinical characteristics,recurrences,metastasis and survivals were retrospectively analyzed.Results The median time of follow-up was 92 months,ranging from 4 to 98 months.41 cases (25.3％,41/162) presented local recurrence or metastasis including 32 cases with metastasis ( 19.8％,32/162),2 cases with local recurrences (1.2％,2/162) and 7 cases with both local recurrence and metastasis (4.3％,7/162) ;Disease-free survival (DFS) and the 5-year DFS were 73.1％ and 79.6％,respectively.27 patients ( 16.7％,27/162) died of breast cancer,the overall survival (OS) and 5-year OS were 82.5％ and 85.3％,respectively.According to Kaplen-Meier survival analysis,tumor size,lymph node status and clinical stage were correlated to overall survival time ( P ＜ 0.05 ) ; and rumor size,lymph node starus,grade,clinical stage and PR status were correlated to disease-free survival time ( P ＜ 0.05 ).By multivariate analysis,TNM stage,PR and PCNA were independent prognostic factors correlated to overall survival time (OR=0.633,95％ CI:0.411 -0.976,P＜0.05; OR =0.823,95％ CI:1.012-3.283,P ＜ 0.05) ; TNM stage and PR was independent prognostic factors correlated to disease-free survival time (OR =3.273,95％ CI:1.719 - 6.232,P ＜ 0.01 ; OR =0.599,95％ CI:0.423 - 0.850,P ＜ 0.01 ).Conclusions In invasive Luminal subtype breast cancers,PR is correlated to fine prognosis,and PCNA is correlated to overall survival time.

OBJECTIVESTo investigate relationship between iron deficiency of different degrees and physical performance and habitual activity of migrant schoolchildren at the age of 11-14 years.

METHODSNinety one randomly selected schoolchildren were divided into three groups according to their iron status. Iron status including hemoglobin (Hb), serum ferritin (SF), serum iron (SI) and sTfR was determined. Physical performance tests included maximum oxygen consumption (VO2max) and maximum work time. Energy expenditure (EE) and daily physical activity were estimated by recording 24-h heart rate (HR). Dietary intake was assessed with frequency questionnaires, and physical activity level was estimated with frequency and physical activity questionnaires.

RESULTSSevere iron deficiency (IDA) impaired the aerobic capacity and habitual physical activity. When fat-free mass (FFM) was considered, VO2max (VO2max/FFM) was significantly lower in the iron-marginal group than in the iron-adequate groups among girls (P = 0.02), but such a deference was not found among boys (P = 0.28). Aerobic activity and EE at leisure were significantly lower in the severe iron deficient group than in the marginal iron deficient and iron adequate groups. Net HR at leisure time was correlated with Hb, log SF, body weight, and FFM (P < 0.05).

CONCLUSIONThe functional effect of iron deficiency on physical performance and habitual physical activity rely on the degree of current iron deficiency. Severe iron deficiency significantly impairs both aerobic capacity and habitual physical activity. Iron-marginal deficiency impairs VO2max/FFM in girls, rather than in boys.
