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.

Comparative StudyEmulsified halothane produces long-term epidural anesthetic effect: a study in rabbits.
Previous studies have demonstrated that volatile anesthetics could produce local anesthesia. Emulsified isoflurane at 8% has been reported to produce epidural anesthetic effect in rabbits. This study was designed to investigate the long-term epidural anesthetic effect of emulsified halothane in rabbits. ⋯ Normal consciousness was found in the rabbits from 8% E-Halo, 8% E-iso and lido groups while there were four rabbits in 12% E-Halo group (4/10) showed a light sedation. For all the rabbits, no pathological injury was found. The present study demonstrates that emulsified halothane produces reversible concentration-dependent epidural anesthesia and at 12% (v/v), emulsified halothane could produce long-term anesthesia without pathological injury.

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.

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.

A modified "double-hit" induced acute lung injury model in rats and protective effects of tetramethylpyrazine on the injury via Rho/ROCK pathway.
We focused on the production and evaluation of a modified "double-hit" induced acute lung injury (ALI) model, which closely mimics the clinical situation. Further, tetramethylpyrazine (TMP), an alkaloid contained in ligustrazine was evaluated for its potent anti-inflammatory effects in this model. Rats were randomized into 4 groups: G1 (NS control group), G2 ("double-hit" group), G3 (low dosage TMP group) and G4 (high dosage TMP group). ⋯ The rats in G3, G4 were intraperitoneally injected with low (G3), high (G4) dosage TMP for the protection against ALI. Upon termination of the experiment, TMP attenuated the harmful changes in animal model reaction, breathing frequency, histological examination, lung W/D-weight ratio, BAL fluid PMNs percentage, MPO activity and ROCK2 mRNA expression. We found inhibiting RhoA/ROCK pathway might attribute to TMP-induced protection against ALI.
