Extra-uterine placental site trophoblastic tumor (PSTT) is extremely rare. To our knowledge, PSTT that occurs in the pelvic wall has not yet been reported. A 29-year-old woman presented with amenorrhea and irregular vaginal bleeding of 1 month. A solid tumor mass was detected by ultrasonography in the right pelvic wall. The tumor was comprised of large, polygonal tumor cells, with brisk mitosis and obvious vascular invasion. Immunohistochemical staining demonstrated that tumor cells were positive for human placental lactogen, CD146, cytokeratin, placental alkaline phosphatase, human chorionic gonadotropin were positive, the Ki-67 proliferative index was about 80%. The pathological diagnosis was PSTT. After the operation, the patient was treated with six cycles of etoposide, methotrexate, actinomycin, cyclophosphamide, and vincristine. The patient was followed for 18 months without recurrence. The report shows that extra-uterine PSTT is extremely rare and may have a good prognosis; surgical resection and adjuvant chemotherapy are good options. However, further experience to diagnose and cure this rare tumor is warranted.

Sexual dimorphism is commonly regarded as an outcome of inter-sexual differences in intensity of sexual selection. In this view, the inter-sexual difference in mass of hind limb muscles of Bufo andrewsi in relation to sexual selection was investigated by dissecting four hind limb muscles (sartorius, plantaris longus, triceps femoris and gastrocnemius) from the left and right side of each individual. The results showed that females significantly exceeded males for muscle sartorius, muscle plantaris longus and muscle gastrocnemius and total mass, independent of body size. There are no significant differences in the four hind limb muscles mass between amplectant and non-amplectant males. Relative hind limb muscle of females is significantly larger than males, but it is not different between amplectant and non-amplectant males. There was no significant or positive correlation between relative hind limb muscle mass and SVL for any of the toads. © NwjZ, Oradea, Romania, 2012.

To study the related factors of patients with intracerebral hemorrhage (ICH) so as to guide treatment and predict prognosis. The prognostic factors of 463 cases with intracerebral hemorrhage were analyzed with single factor and Logistic regression analyses. Age, Glasgow coma scale, amount of hemorrhage, NIHSS score, mean arterial blood pressure, with or without ventricular breakage, with or without midline shift and the incidence of complications at random blood glucose levels were analyzed for the correlation with the prognosis of patients. The poor prognosis group had significant differences with the good prognosis group with regards to these factors. The average age of patients with a poor prognosis was 71 years old, the average hematoma volume 29 ml and the average GCS score 11.2 versus 65 years old, 15 ml, 15.1 for those with a good prognosis (P < 0.05). Logistic regression analysis showed that age, amount of hemorrhage and disturbance of consciousness was an independent adverse prognostic factor for cerebral hemorrhage at three months. The OR values were 1.32, 8.66 and 1.08 respectively. The etiologies of ICH are diverse. Maintaining normal blood pressure is an important preventive measure for ICH. Hematoma volume, disturbance of consciousness and age may be used to predict the prognosis of cerebral hemorrhage.

The aim of this study was to evaluate the efficacy and safety of the combination of docetaxel (TXT) plus tamoxifen (TAM) in advanced non-small-cell lung cancer (NSCLC) patients who had received platinum-based first-line chemotherapy. A total of 120 advanced NSCLC patients pretreated with platinum-based chemotherapy were randomized into two treatment groups (the TXT and TXT+TAM groups) in a 1 : 1 ratio. Reversal of P-glycoprotein (P-gp) expression, tumor response, progression-free survival, overall survival, and safety were evaluated on an intention-to-treat basis. The median number of cycles of allocated chemotherapy was four in each treatment group (range: 2–6 cycles). The overall response rate and disease control rate in the TXT+TAM group were significantly higher than those in the TXT group (36.7 vs. 15.0% for overall response rate, P=0.007; 85.0 vs. 68.3% for disease control rate, P=0.031). The combination of TXT and TAM could effectively reverse P-gp expression in tumor tissues and provide a significant survival benefit for advanced NSCLC patients compared with TXT alone (11.6 vs. 9.1 months, P=0.030). In addition, in the TXT+TAM group, patients achieving P-gp reversal had a significantly greater median progression-free survival and overall survival than nonreversal patients. Furthermore, the combined therapy showed a safety profile comparable to that of TXT. The combination of TXT and TAM may be an effective and safe treatment option for advanced NSCLC patients who have already developed P-gp-mediated multidrug resistance.

Background Gemcitabine and pemetrexed have been used as maintenance therapy. However, few systematic reviews and meta-analyses have assessed their effects in the newest studies. This systematic review and meta-analysis were conducted to assess the role of gemcitabine and pemetrexed in the maintenance treatment of non-small-cell lung carcinoma (NSCLC). Methods We performed a literature search using PubMed, EMBASE and Cochrane library databases from their inceptions to September 16, 2015. We also searched the American Society of Clinical Oncology (ASCO), European Society for Medical Oncology (ESMO), and National Comprehensive Cancer Network (NCCN) databases from 2008 to 2015. Two authors independently extracted the data. The Cochrane Collaboration's risk of bias graph was used to assess the risk of bias. The GRADE system was used to assess the grading of evidence, and a meta-analysis was conducted using Stata 11.0 software. Results Eleven randomized controlled trial (RCT) studies were collected. Ten studies were included in the meta-analysis and divided into the following 4 groups: gemcitabine vs. best supportive care (BSC)/observation, pemetrexed vs. BSC/placebo, pemetrexed + bevacizumab vs. bevacizumab and pemetrexed vs. bevacizumab. Gemcitabine exhibited significantly improved progression-free survival (PFS) compared with BSC (hazard ratio (HR) = 0.62, p = 0.000). Pemetrexed exhibited significantly improved PFS (HR = 0.54, p = 0.000) and OS (HR = 0.75, p = 0.000) compared with BSC. Pemetrexed + bevacizumab almost exhibited significantly improved PFS (HR = 0.71, p = 0.051) compared with bevacizumab. Pemetrexed exhibited no improvement in PFS or overall survival (OS) compared with bevacizumab. Regarding the grade, the GRADE system indicated that the gemcitabine group was "MODERATE", the pemetrexed group was "HIGH", and both the pemetrexed + bevacizumab vs. bevacizumab groups and pemetrexed vs. B groups were "LOW". Conclusions Gemcitabine or pemetrexed compared with BSC/observation/placebo significantly improved PFS or OS. Whether pemetrexed + bevacizumab compared with bevacizumab alone significantly improves PFS requires further investigation. © 2016 Hu et al.
