Objective To study the value of sentinel lymph node (SLN) for forecasting axillary lymph node metastasis in breast cancer. Methods Fifty-six patients with breast cancer underwent SLN methylene blue mapping and biopsy,as well as axillary lymph node dissection.All lymph nodes received routine HE staining and immunohistochemical examination. Results SLN was successfully identified in 52 cases (52/56,92.8%).Routine pathological examination demonstrated metastasis of SLN in 22 cases and metastasis of non-SLN in 1 case,the false negative rate being 4 3% (1/23).In the remaining 29 cases without pathologically verified metastasis,immunohistochemical staining showed 1 case of CK-19 (+) with EMA (+) and another 1 case of CK-19 (+) with CEA (+),without metastasis of non-SLN. Conclusions SLN methylene blue mapping and biopsy may forecast axillary lymph node metastasis in breast cancer.

Objective To investigate the feasibility of breast conservative surgery for large breast carcinoma(over 3 cm in diameter)after neoadjuvant chemotherapy.Methods A total of 24 patients with breast carcinoma larger than 3 cm in diameter underwent core needle biopsy and neoadjuvant chemotherapy with paclitaxel and/or epirubicin in our hospital from June 2003 to September 2006.The chemotherapy was carried out for 2 to 4 cycles,and then breast conservative surgery was performed in 7 to 10 days.Results After the neoadjuvant chemotherapy,3(12.5%)patients achieved CR,and 21(87.5%)had PR.Pathological CR was detected in 2(8.3%)of the patients.The breast conservative surgery was completed in 14 cases(58.3%),10 patients were converted to modified radical resection.The patients was followed up for 5 to 44 months with a median of 24,during which none of them had recurrence or distant metastasis.Conclusions For patients with large breast carcinoma,breast conservative surgery is feasible after neoadjuvant chemotherapy.

Objective To analyze the clinical pathologic features and prognosis of triple negative breast cancer. Method A total of 570 cases of breast cancer between January 2005 and June 2007 were analyzed,113 cases were negative for estrogen receptor(ER), progesterone receptor(PR) and HER-2 as the triple negative group, 48 cases were negative for ER, PR and positive for HER-2 as the control group. The clinical pathologic features, recurrence and survival of the patients were compared. Results The median age was 46 years old, 15 cases (13.3%) had a breast cancer family history or oophoroma family history,86.7%(98/113) of pathological types were invasive ductal carcinoma,lymph node metastases were detected in 31.0%(35/113 ) in the triple negative group. No significant difference was found for p53 staining between the triple negative group[58.4%(66/113)positive] and the control group [41.7%(20/48) positive] (P＞0.05).The median time of follow-up was 24 months,the loss was 5 cases, 10 cases (9.3%, 10/108) had local recurrence and metastasis,and 8 cases (7.4%,8/108) died from breast cancer metastases,2-year survival rate was 96.2% in the triple negative group.There was no significant difference in local recurrence and survival time between the triple negative group and the control group (P＞0.05). Conclusions The incidence of triple negative breast cancer is higher than other data reported. Triple negative breast cancer exhibits the same clinical pathological features compared with ER-/PR-/HER-2 + subtypes,and the prognosis is similar to the controls.

To investigate the mechanism of agarwood formation in Aquilaria sinensis induced by Lasiodiplodia theobromae, the fermentation liquor of L. theobromae was analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). JAs were detected in the fermentation liquor. The effect of the fermentation liquor on the abundance of sesquiterpenes in the callus of A. sinensis was analyzed by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). And the fermentation liquor stimulated alpha-guaiene, alpha-humulene and delta-guaiene biosynthesis in calli. It was inferred that L. theobromae produced JAs, which resulted in a significant increase of sesquiterpenes in A. sinensis.

OBJECTIVETo investigate the main factors that influence measles morbidity and the genotype of measles virus, so as to provide evidence for scientific decision making to further control the prevalence of measles.

METHODA retrospective analysis included 182 children in Children's Hospital of Fudan University, diagnosed with measles from January 1, 2012 to December 31. The clinical and epidemiological characteristics, including the gender, age, the incidence of seasonal trends, measles vaccine vaccination history, contact history and other clinical manifestations, laboratory test results, and so on were analyzed. And the reverse transcription PCR (RT-PCR) was adopted to detect sputum specimens from suspected patients with measles,who were selected randomly,the sequence of the part of the PCR products was analyzed.

RESULT(1) Clinical and epidemiological data: Totally were 182 children with measles (125 males, 57 females) were enrolled into this study. The age of the patients ranged from 3 months to 89 months, 127 cases were younger than 9 months (69. 8%). The prevalence season was from April to August, while the peak month was April and May (22. 5%, 23. 1%). Among 182 hospitalized children, only 11 cases underwent measles vaccination (6. 0%), and among them 5 cases were within 2 weeks before disease onset. A total of 167 cases (91. 8%) had not been vaccinated, most of whom were immigrants, and the measles vaccination history of the remaining 4 cases were unknown. There was a positive correlation between the measles vaccination ratio in children of the floating population (8. 45%, 6/71) and the settled children (29.4%, 5/17, χ =8. 11 P =0. 004). In total, 24 cases (13. 2%) had definite measles exposure history, with 153 cases (84. 1%) of unknown origin,5 cases (2.7%) without any history of contact. (2) Clinical manifestations: All the 182 patients had fever (100%) and obvious rashes (100%), among them 145 cases had body temperature higher than 39 °C (79. 7%). The fever period ranged from 2 to 38 days. Among 182 hospitalized children,165 cases (90. 7%) had typical measles,17 cases had atypical measles. Among the 17 cases, two had severe measles, one had heterotypic measles. (3) The common complica tions: 96 cases had pneumonia (52. 8%), 80 had laryngitis (44. 0%), 38 had bronchitis (20. 9%),15 had hepatic dysfunction (8. 2%), 11 had myocardial damage (6. 0%), 3 had febrile seizures (1. 6%), and no patient had encephalitis. Of the 96 cases with pneumonia, 92 received sputum test; 38 were sputum culture positive (41%). The dominant pathogens were Streptococcus pneumoniae(11/38,29%), Haemophilus influenzae (6/ 38,16%), Moraxella catarrhalis (4/38, 11%), Escherichia coli (4/38, 11%), Candida albicans (4/38, 11%), Mycoplasma pneumoniae (4/38, 11%) and Staphylococcus aureus (3/38, 8%). (4) The H1a genotype was the only one genotype in the detected sequence of 54 measles virus strains.

CONCLUSIONMeasles was more often seen in the children under the age of 9 months from the floating population. The morbidity peak month was from April to May in Shanghai. The H1a genotype was the only one genotype. We should try to improve vaccination coverage rate in the children who are at the age for vaccination, so as to prevent measles outbreak.

Objective To evaluate the clinical value of the real-time three-dimensional ultrasound in the diagnosis of the fistula-in-ano.Methods One hundred and eighteen fistula-in-ano patients were examined using conventional and three-dimensional ultrasound,the stereotaxis of interal opening and the shape of the fistula-in-ano were analyzed.Then the diagnosis results of ultrasound were compared with the surgery and pathology.Results In 1 1 8 patients,the accuracy of preoperative identifying internal opening by two-dimensional ultrasound was 85%,and 95% for three-dimensional ultrasound with statistically significant difference (χ2 =6.679,P <0.05).For complex anal fistula,the diagnostic accuracy rates of main fistula tract by three-dimensional ultrasound (100%,82/82 )was higher than that by two-dimensional ultrasound(95%,78/82),the difference was statistically significant (χ2 =4.100,P <0.05 ).In 82 cases of complex anal fistula,the diagnostic accuracy of branch fistula tract by two-dimensional ultrasound was 70%(57/82 ),the accuracy using three-dimensional ultrasound was 89% (73/82 ),there was statistically significance (χ2 =9.499,P < 0.05 ).Conclusions Three-dimensional ultrasound can accurately locate the interal opening of fistula-in-ano and determine the shape of fistula-in-ano,which provided the most intuitive information for clinical treatment and had high practical value.

Objective To evaluate the relationship between 25-(OH) vitamin D [25-(OH) D] level and peripheral neuropathy in patients with type 2 diabetes mellitus.Methods Eighty patients with type 2 diabetes mellitus were enrolled in this cross-sectional study,including 37 subjects with and 43 without diabetic neuropathy.Anthropometric data was collected and serum levels of 25-(OH) D,HbA1c,blood lipid,and hepatic and renal functions were determined in all patients.Results Serum 25-(OH) D level was significantly lower in patients with diabetic neuropathy compared to those without neuropathy [(12.73 ± 4.68 vs 17.56 ± 5.28) ng/ml,P＜0.01].Logistic regressions demonstrated that vitamin D level was associated with diabetic neuropathy (OR=1.222,95％ CI 1.095-1.364).Conclusions Vitamin D insufficiency is associated with diabetic peripheral neuropathy.25-(OH) D level seems to be an independent risk factor of diabetic neuropathy in patients with type 2 diabetes mellitus.
