Case ReportsMultfocal micronodular pneumocyte hyperplasia in a Chinese man masquerading as miliary tuberculosis.
Multifocal Micronodular Pneumocyte Hyperplasia (MMPH) is a rare and histologically, distinctive pulmonary manifestation of tuberous sclerosis complex (TSC) characterized by numerous and extensive proliferative lesions of type II pneumocytes similar to atypical adenomatous hyperplasia (AAH) or non-mucinous adenocarcinoma in situ (AIS). We reported MMPH in a 38-year-old Chinese man with TSC masquerading for 16 months as miliary tuberculosis and discussed the differential diagnosis.

Association of GSTP1 and XRCC1 gene polymorphisms with clinical outcome of advanced non-small cell lung cancer patients with cisplatin-based chemotherapy.
We investigated the association between the clinical outcome and GSTP1 and XRCC1 gene polymorphisms in advanced NSCLC patients with cisplatin-based chemotherapy. We prospectively recruited 325 NSCLC patients between January 2010 and January 2014. Genotypes of GSTP1 A313G, XRCC1 Arg194Trp, Arg280His and Arg399Gln were conducted using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assay. ⋯ In the Cox proportional hazards model, GG genotype of GSTP1 A313G was significantly correlated with a longer median survival time when compared with AA genotype, and it is associated with a heavy decreased risk of death from NSCLC. Moreover, GA and AA genotypes of XRCC1 Arg399Gln had a significantly longer median survival time, and GA and AA genotypes were significantly associated with a moderate reduced risk of death from NSCLC. GSTP1 A313G and XRCC1 Arg399Gln gene polymorphisms might influence the response to cisplatin-based chemotherapy and affect the clinical outcome of advanced NSCLC.

CGRP 4218T/C polymorphism correlated with postoperative analgesic effect of fentanyl.
Our study aimed at evaluating the association between α-calcitonin gene-related peptide (CGRP) 4218T/C polymorphism and the patient-controlled analgesic (PCA) effect of fentanyl on Chinese Han population. ⋯ CGRP 4218T/C polymorphism may be associated with the postoperative fentanyl consumption for analgesia.

Case ReportsEndometrial tubal metaplasia in a young puerperal woman after breast cancer.
Tamoxifen is the usual endocrine (anti-estrogen) therapy for hormone receptor-positive breast cancer in pre and post-menopausal women. Previous studies have suggested an increased prevalence of endometrial diseases after treatment with tamoxifen. ⋯ Tamoxifen is a safe and reliable treatment of breast cancer, but data suggest an association with endometrial polyps, hyperplasia, metaplasia and carcinoma. One of the most common types of endometrial metaplasia is ciliated tubal metaplasia. It is generally known that endometrial tubal metaplasia is a benign disease. However studies propose endometrial tubal metaplasia to be a potential premalignant endometrial lesion and its association with endometrial hyperplasia and well-differentiated endometrioid carcinoma. We propose close monitoring of patients taking tamoxifen and prompt evaluation of any uterine bleeding or pelvic complaint or abnormal TVUS images.

Downregulation of NUF2 inhibits tumor growth and induces apoptosis by regulating lncRNA AF339813.
Recent studies have shown that NUF2 (Ndc80 kinetochore complex component) play important roles in multiple human cancers. In our previous report, NUF2 expression was stronger in tumor tissues than in normal pancreatic tissues. However, whether and how NUF2 play a role in pancreatic cancer progression remains largely unknown. ⋯ We further demonstrated that knockdown of AF339813 by siRNA in PC cells significantly reduced cell proliferation and promoted apoptosis. Thus, we conclude that NUF2 is consistently overexpressed in human PC and NUF2 is closely linked with human PC progression through the meditator LncRNA AF339813. Our studies may contribute to understand the molecular mechanism of PC pathogenesis and clinical therapy.
