Purpose To investigate the clinicopathologic features and prognostic factors of apocrine carcinoma ( AC) of breast. Meth-od Clinical data of 70 ACs and 283 invasive carcinomas, not otherwise specified were collected. Differences between the prognostic outcomes of the two groups were compared, and the relationship between clinicopathological characteristics and prognosis was also ana-lyzed. Results The mean age of the patients with AC (56. 17 ± 12. 41 years) was older than those with invasive carcinoma not other-wise specified (52. 77 ± 11. 07 years) (P=0. 039). The patients with AC had a lower frequency of axillary nodal metastasis, a lower frequency of ER and PR positivity comparing to invasive carcinoma not otherwise specified ( P<0. 05 ) . No significant differences in the overall survival (P=0. 221) and disease-free survival (P=0. 378) periods of the two groups were observed. Kaplan-Meier surviv-al analysis showed tumor size, lymph node metastasis, pathological stage, lymph node tissue infiltration were related with prognosis of patients with AC ( P<0. 05 ) . In multivariate analysis, lymph node metastasis was associated with a worse prognosis ( P<0. 05 ) . Conclusions Although AC and invasive carcinoma not otherwise specified have different clinicopathologic characteristics, the prog-noses of patients with these diseases are similar. Lymph node metastasis could be used as an independent factor for predicting the prog-nosis of patients with AC, early diagnosis and early treatment is the key to improve its prognosis.

Objective To investigate the values of CD21 and CD43 proteins in the differential diagnosis of mucosa-associated marginal zone B-cell lymphoma (MALToma) from benign lymphadenosis. Methods The expression of CD21 and CD43 proteins in the tissues of 25 MALToma (case group) and 25 benign lymphadenosis (control group) was detected by immunohistochemistry. Results Abnormal CD21+follicular dendritic cells (FDC) meshes were found in all patients of case group. Most of the FDC meshes were sparse and broken, and a few were enlarged or fused into pieces. Intact CD21+FDC meshes were all found, and abnormal FDC meshes were not found in control group. The positive rate of abnormal FDC meshes in case group was significantly increased compared with that in control group (χ2 = 46.080, P= 0.000). The expression rate of CD43+in CD20+cells was 24 % (6/25) in case group, but it was negative in control group (χ2=4.375, P=0.030). Conclusions Abnormal CD21+FDC meshes and CD43+expression in CD20+cells are useful in the differential diagnosis between MALToma and benign lymphadenosis. The abnormal FDC meshes of MALToma are enlarged or fused in the minority of cases.

Objective To analyze the results of the assessment of malaria elimination in 8 counties(districts)in Huai'an City,Jiangsu Province,so as to provide evidences for consolidating the achievement of malaria elimination. Methods The da-ta from the network reports of malaria epidemic situation,blood examinations of febrile patients,epidemiological questionnaires of malaria cases,investigation and disposal of epidemic focuses were collected and analyzed in Huai'an City from 2010 to 2016. The results of the assessment on the clinicians'ability of malaria diagnosis and treatment as well as the inspectors'skill of Plas-modium microscopic examinations were analyzed. In the natural village where the last local case of malaria was reported ,no less than 200 blood filter papers were made for gene detection of Plasmodium. Results From 2010 to 2016,308 malaria cases were reported in Huai'an City. Totally 323002 patients received blood detection of malaria,among which 272 ones were positive and the positive rate was 0.08%. The majority of the malaria cases were imported,except 19 and 3 local infection cases in 2010 and 2011,respectively. Except Qinghe District,a total of 1420 blood filter papers from the other 7 counties(districts)were detect-ed genetically,and the results were all negative. Six of the eight counties(districts)gained an average score of 20 points on the Plasmodium microscopic examination,and Jinhu County and Huai'an District got a minimum average score of 19.6 points. In ca-pacity assessment of malaria diagnosis and treatment,Hongze District gained the highest average score of 20 points,and Huai'an District got the lowest average score of 18.8 points. The malaria elimination assessment scores of the eight counties(districts) were all above 97 points. All the 8 counties(districts)in Huai'an City passed the malaria elimination assessment at county(dis-trict)level until 2016. Conclusions All the 8 counties(districts)in Huai'an City have passed the malaria elimination assess-ment with high scores. After the malaria elimination,the monitoring still should continue to consolidate the achievement.

Objective To determine sonographic features and outcome of fetal lung abnormal lesions. Methods Blood supply of the lesion, fetus hydrops and other extra-lung anomalies should be evaluated by color Doppler flow image(CDFI) when abnormal lesion was detected in fetus lung during routine scanning. The fetus with lung abnormal lesion without hydrops at the first time scanning should be monitored by ultrasound in every four to six weeks. Results Forty cases fetus presented lung abnormal lesions, which included 21 cases with hyperechogenic solid masses,15 cases with cystic-solid mixture masses,4 cases with cystic masses. Lesions of 8 cases were demonstrated systemic arterial blood supply arising from the aorta on CDFI and the diagnosis of pulmonary sequestration (PS) were suggested. Seventeen cases lesion that had small size or decreased or disappeared or remained stable in size with gestational age developing had normal neonate. Conclusions CDFI is very useful in detecting abnormal lesion of the fetal lung and differentiating pathology and evaluating the prognosis. The outcome of isolated lung lesion without hydrops and mediastinal shift that decreased or disappeared or remained stable in size had a good prognosis.

The aim of this study was to investigate the effect of Compound Yihe Tea on improving insulin resistance in obesity mice. Thirty-two male C57BL/6J mice were randomly divided into 4 groups: the normal fat diet group(NFD group), high fat diet group(HFD group), Compound Yihe Tea low dosage group[20 mg/(kg ·d), YH-L group] and high dosage group[40 mg/(kg ·d), YH-H group]. NFD group was given standard feed, and the remaining mice were administered with high fat diet. After 6 weeks, YH-H and YH-L groups were given Compound Yihe Tea for 6 weeks. Blood glucose was measured at week 11 and serum levels of total cholesterol(TC), serum triglyceride(TG), low-density lipoprotein cholesterol(LDL-C)and high-density lipoprotein cholesterol(HDL-C)were measured at week 12. Liver tissues were prepared for oil red O and HE staining. Immunohistochemical analysis was used to test the protein expression of GLUT4 in liver. Protein expressions of PI3K, Akt and GLUT4 in epididymis white adipose tissue(WAT)were tested by Western blot. The results showed that Compound Yihe Tea could effectively reduce body weights and the serum levels of TC, TG and LDL-C. Furthermore Compound Yihe Tea could improve the histopathological changes of liver, up-regulate the protein expression of PI3K, Akt and GLUT4 in epididymis WAT and the protein expression of GLUT4 in liver. Compound Yihe Tea can reduce the fat accumulation in liver tissue, improve the indexes of blood glucose and lipid levels, and improve insulin resistance via PI3K-AKT-GLUT4 pathway.

Purpose To investigate the diagnostic utility of the immunohistochemical markers SALL4, D2-40 and Glypican-3 in prima-ry testicular germ cell tumors (TGCTs). Methods The expression of SALL4, D2-40 and Glypican-3 protein was detected by EnVi-sion immunohistochemical method in 56 cases of primary testicular germ cell tumors, including 5 intratubular germ cell neoplasms ( IT-GCNs) , 10 seminomas, 14 embryonal carcinomas ( ECs) , 14 yolk sac tumors ( YSTs) , 1 choriocarcinoma, 5 immature teratomas and 12 mature teratomas. 10 normal testicular tissues and 5 lymphomas were selected as control. Results All of ITGCNs, seminomas, YSTs and ECs were diffusely strongly positive for SALL4. Focal SALL4 staining was seen in choriocarcinoma, 3 of 5 immature terato-mas and 3 of 12 mature teratomas. All of ITGCNs, seminomas showed diffusely strong D2-40 staining. ECs (4/14) were focally posi-tive for D2-40, while choriocarcinoma, YSTs and teratomas were negative for D2-40. Glypican-3 was diffusely positive in YSTs (13/14), and focally weakly positive in ECs (2/14), respectively. ITGCNs, seminomas, choriocarcinoma and teratoma were negative for Glypican-3. In contrast, 10 normal testicular tissues and 5 lymphomas showed no SALL4, D2-40 and Glypican-3 staining. Conclu-sions SALL4 is a useful diagnostic marker with high sensitivity and specificity for TGCTs. Combination of SALL4, D2-40 and Glypi-can-3 is helpful to the diagnosis and differential diagnosis for TGCTs.
