Objective: To analyze the serotype distribution and drug resistance of Streptococcus pneumoniae isolated from pediatric patients in a Chinese hospital. Methods: From October 2011 to May 2014, we collected 284 isolates (including 217 noninvasive and 67 invasive strains). We tested the antimicrobial susceptibility of these specimens using the Epsilomer test and disk diffusion method, and the expression of macrolide resistant genes ermB and mefA by polymerase chain reaction. Results: The most common serotype for 217 noninvasive strains was 19F (31.3%). The coverage rates of the 7-, 10-, and 13-valent pneumococcal conjugate vaccines (PCV7, PCV10, and PCV13) were 53.9%, 53.9%, and 86.2%, respectively. For 67 invasive strains, the most common serotype was 23F (22.4%). The coverage rates of PCV7, PCV10, and PCV13 for invasive strains were 77.6%, 82.1%, and 91.0%, respectively. The susceptibility of strains isolated from nonmeningitis specimens to penicillin (PEN) was 97.2%. The rate of multidrug resistance in 284 isolates was 98.7%. All of these isolates were resistant to erythromycin (ERY) and had the ermB gene; 38.6% of those isolates had the mefA gene. Conclusions: Compared with PCV7 and PCV10, the coverage rate of PCV13 was relatively higher for the S. pneumoniae isolates from pediatric patients. This finding suggests that PCV13 probably plays the strongest role in prevention of pneumococcal diseases and control of multidrug resistance. Because pneumococci were sensitive to PEN, this drug is still the preferred choice for clinical treatment of pediatric pneumococcal diseases. VC American Society for Clinical Pathology, 2016.

Medications administered during the neonatal period may mask the diagnosis of congenital hypothyroidism. Herein, we report a case of undiagnosed congenital hypothyroidism while the infant was on treatment with dopamine. Given the inhibitory effect of dopamine on thyroid-stimulating hormone, a high index of suspicion for potential congenital hypothyroidism is needed in such neonates. © The Author [2015].

An increasing number of TFE3 rearrangement- associated tumors, such as TFE3 rearrangement-associated perivascular epithelioid cell tumors (PEComas), melanotic Xp11 translocation renal cancers, and melanotic Xp11 neoplasms, have recently been reported. We examined 12 such cases, including 5 TFE3 rearrangement-associated PEComas located in the pancreas, cervix, or pelvis and 7 melanotic Xp11 translocation renal cancers, using clinicopathologic, immunohistochemical, and molecular analyses. All the tumors shared a similar morphology, including a purely nested or sheet-like architecture separated by a delicate vascular network, purely epithelioid cells displaying a clear or granular eosinophilic cytoplasm, a lack of papillary structures and spindle cell or fat components, uniform round or oval nuclei containing small visible nucleoli, and, in most cases (11/12), melanin pigmentation. The levels of mitotic activity and necrosis varied. All 12 cases displayed moderately (2+) or strongly (3+) positive immunoreactivity for TFE3 and cathepsin K. One case labeled focally for HMB45 and Melan-A, whereas the others typically labeled moderately (2+) or strongly (3+) for 1 of these markers. None of the cases were immunoreactive for smooth muscle actin, desmin, CKpan, S100, or PAX8. PSF-TFE3 fusion genes were confirmed by reverse transcription polymerase chain reaction in cases (7/7) in which a novel PSF-TFE3 fusion point was identified. All of the cases displayed TFE3 rearrangement associated with Xp11 translocation. Furthermore, we developed a PSF-TFE3 fusion fluorescence in situ hybridization assay for the detection of the PSF-TFE3 fusion gene and detected it in all 12 cases. Clinical follow-up data were available for 7 patients. Three patients died, and 2 patients (cases 1 and 3) remained alive with no evidence of disease after initial resection. Case 2 experienced recurrence and remained alive with disease. Case 5, a recent case, remained alive with extensive abdominal cavity metastases. Our data suggest that these tumors belong to a single clinicopathologic spectrum and expand the known characteristics of TFE3 rearrangement-associated tumors. © 2015 Wolters Kluwer Health, Inc.

In this study, the current status for breast diseases in a region with high-incidence of cervical cancer were epidemiologically investigated. From March to August, 2009, 17618 women, from Wufeng area of Hubei province, China, were recruited to screen breast diseases by using breast infrared diagnostic apparatus. Other diagnostic methods, such as B-mode ultrasound, X-ray mammography, needle biopsy and pathological examination were, if necessary, used to further confirm the diagnosis. The screening showed that 5990 of 17618 cases (34.00%) had breast diseases, 5843 (33.16%) had mammary gland hyperplasia, 48 (0.27%) had breast fibroadenoma, 11 (0.06%) had breast carcinoma, and 88 (0.50%) had other breast diseases. The peak morbidity of breast cancer was found in the women aged 50-60 ages. The morbidity of breast cancer was significantly increased in women elder than or equal to 50 years old (n=8, 0.157%) in comparison with that in the subjects younger than 50 years old (n=3, 0.024%) (u=2.327, P<0.05). It was shown that the occurrence of breast diseases was concentrated in women aged 20-40 years, while the total morbidity reached its peak at the age of 30 years and then decreased sharply after age of 40. Compared with the patients elder than or equal to 40 years old (n=3289, 27.46%), the morbidity rate of breast diseases was significantly increased in women less than 40 years old (2648 cases, 47.18%; P<0.001). However, there was no significant difference in the morbidity of breast diseases between the age group of 20-29 years and that of 30-39 years (P=0.453), and both of them were high. There was no significant association between the morbidity of breast diseases and cervical cancer. Since the morbidity of breast diseases was higher among young women, more attention should be paid to the screening of breast diseases among young women for early diagnosis. © Huazhong University of Science and Technology and Springer-Verlag Berlin Heidelberg 2012.

Background: Decay-accelerating factor (DAF) is one of the key molecules involved in cell protection against autologous complement, which restricts the action of complement at critical stages of the cascade reaction. The effect of DAF on the survival of human cervical cancer cell (ME180) has not been demonstrated. Methods: In this study we applied, for the first time, small interference RNA (siRNA) to knock down the expression of the DAF with the aim of exploiting complement more effectively for tumor cell damage. Meanwhile, we investigated the effects of DAF on the viability and migration, moreover the proliferation of ME180 cell. Results: The results showed that the expression of DAF was significantly increased in human cervical cancer tissues. SiRNA inhibition of DAF expression enhanced complement-dependent cytolysis up to 32% in ME180 cells, which contributed to the control of C3 activation and increased the cells viability, migration and augment the number of ME180 cells. Conclusion: These data indicated that DAF siRNA described in this study may offer an additional alternative to improve the efficacy of antibody- and complement-based cancer immunotherapy. © 2010 Springer-Verlag.
