Objective To summarize the clinical characteristics of foreign accent syndrome (FAS) among Chinese. Methods The journal articles published in Chinese between 1980 and 2011 were retrieved with three Chinese translated versions of FAS as the key words, and 38 articles in line with the inclusion criteria were systematically analyzed. Results and Conclusion Each year, about (3.06±1.65) cases were published on FAS ever since 1996. The age of FAS patients was averagely around 38.10 years, and of the reported cases, there were 26 males and 23 females, there is no significant difference in gender (χ2=0.184, P=0.668). The etiological factors of FAS were identified mainly as injury (59.19%), stroke (32.65%) and psychogenic disorder (8.16%), and 65.31% of the focus were found at the left side of brain.85.72 % of the FAS patients were seen to be speaking a new dialect used by a larger population. 80% of the patients who didn't suffer from a coma changed their accent in 72 h following the injury, while 72.73% of those once in a coma changed their accent as they gained consciousness.The prognosis of FAS was fine, with an improvement rate of 70.83%, and 73.53 % of the patients began to recover less than 3 months later following the injury.

Objective To investigate the expressions of nitric oxide synthase (NOS) protein and mRNA in the lung of rats with hepatopulmonary syndrome. Methods Male Sprague-Dawley rats were divided into four groups: sham operation (SO), intrahepatic portal hypertension (IHPH), prehepatic portal hypertension (PHPH) and portasymstimic shunt (PCS). Two weeks after preparation of rat models, the following measurements were performed: arterial blood gas analysis; the concentrations of NO in lungs; in situ hybridization of ecNOS and iNOS mRNA expressions in lung tissue sections with digoxin-labeled ecNOS and iNOS oligonucleotide probes; expressions of ecNOS and iNOS proteins by immunohistochemisty; image and semiquantitative analysis of the expressions of ecNOS, iNOS and their mRNA. Results PaO_ 2 was (73.85?6.51) mmHg in IHPH rats, significantly lower than that in PHPH, PCS and SO rats97.39? 1.33, 95.23?2.22 and (99.05?0.75)mmHg, respectively.The level of lung NO of IHPH was(19.78?5.33)?mol per gram of protein,much higher than that of PHPH, PCS and SO 13.21?3.99,13.89?3.16 and (8.71?1.68)?mol per gram of protein,respectively. In capillary endothelia, positive expressions of ecNOS mRNA and ecNOS protein in IHPH(4.96?0.82,4.11?0.28) were significantly higher than those of PHPH (1.81? 0.39, 1.63?0.18), PCS (1.88?0.53,1.83?0.16)and SO(1.19?0.32,0.98?0.20). Conclusion The expressions of NOS protein and mRNA in the lung of rats with hepatopulmonary syndrome were increased, and the level of lung NO was elevated, which seems to play an important role in the pathogenesis of hepatopulmonary syndrome.

The genetic diversity of three Tibetan herbs, i. e., Sang-Di, E-Dewa and Ye-Xingba (Tibetan names), was studied based on the field collection, specimen identification and DNA sequence analysis. Swertia hispidicalyx, Gentiana lhassica and Scrophularia dentata, as the original plants of the three Tibetan herbs, were collected and identified. The regions of ITS, matK, rbcL, rpoC1, trnL(UAA), psbA-trnH, atpB-rbcL, trnS (GCU)-trnG(UCC), rpl20-rps12, trnL(UAA)-trnF(GAA) and nadl 2nd intron were amplified and sequenced. The ITS regions of S. hispidicalyx and S. dentata were cloned and sequenced, and the sequences were classified into different genotypes. All the sequences were analyzed and compared with those of closely related species. Our studies may provide reference for the genetic diversity analysis and molecular identification of the three Tibetan herbs.

Objective To summarize the risk factors, the diagnostic and therapeutic approaches, and the outcomes of the ruptured primary hepatocellular carcinoma (PHC) occurred after transcatheter arterial chemoembolization (TACE) in order to make a further understanding of this complication. Methods The clinical data of 8 patients with ruptured PHC after TACE, who were encountered at the First Affiliated Hospital of Suzhou University during the period from Sep. 2007 to Sep. 2013, were retrospectively analyzed. Results A total of 1379 times of TACE were performed in 678 patients with PHC. Among the 678 patients, 8 developed rupture of PHC with bleeding after TACE. The overall incidence was 1.2%. The mean diameter of the tumors in the 8 patients was (11.5 ± 2.6) cm, ranging from 7.6 cm to 15.9 cm. All the lesions were located at the peripheral region close to the liver capsule, and most of them protruded outward. Five cases had coexisting portal hypertension. The average dosage of Lipiodol used in TACE was (14.9 ± 4.5) ml with a range of (8 - 20) ml. Of the 8 patients, emergency transcatheter embolization was carried out in 4 and medical management was employed in other 4. Seven patients died as all active emergency treatments failed. Only one patient, who had received emergency transcatheter embolization, survived the ruptured PHC. Conclusion Rupture of primary hepatocellular carcinoma after TACE is a rare, but very serious complication. Its occurrence may be related to lesion’s characteristics, such as large tumor size, superficial location and protrusion from the liver surface, etc. Besides, interventional management, e.g. without use of solid embolic material to enhance the embolization effect, may also be responsible for the rupture.

Objective To elucidate the differences between invasive micropapillary carcinoma (IMPC) and invasive ductal carcinoma(IDC),and explore the clinicopathological and immunohistochemistry characteristics of invasive micropapillary carcinoma of the breast.Methods Invasive micropapillary carcinoma was identified in 51 patients by retrospective review of database from October 2004 to November 2007.Data were compared with 102 patients identified as invasive ductal carcinoma available in this hospital during the same period.Results Significant differences were observed in mammilla invasion,lymphatic vessel invasion,positivity of lymph node,lymph node metastatic level,extranodal extension,estrogen receptor,progestin receptor,triple negative between the two groups; while there was no significant differences between the two groups as to amenorrhea status,lesion laterality,number of metastatic lymph nodes,human epidermal growth factor receptor-2,local recurrence and distant organ metastasis.The median follow-up time of the invasive micropapillary carcinoma group were 46 months ( 16 - 75 months),and the 3-year overall survival and disease free survival was 90.2％ and 84.3％,respectively.Conclusions Invasive micropapillary carcinoma is a unique subtype of breast cancer which manifests an aggressive behavior tending to involve lymph node and extranodal soft tissues.Invasive micropapillary carcinoma of the breast had high expression of hormonal receptors,and triple negative breast cancer is less common in this type of breast cancer.

Objective:To evaluate the safety and efficacy of a palliative regimen of computed tomography (CT)-guided 125I seed im-plantation combined with chemotherapy for recurrent ovarian cancer. Methods:A total of 21 patients with recurrent ovarian cancer, who received 125I seed implantation and chemotherapy, were retrospectively analyzed. Out of the 29 lesions detected, 25 lesions were suitable for 125I seed implantation. Treatment planning system (TPS) was implemented preoperatively to determine the number and dis-tribution of 125I seeds. Under CT guidance, 125I seeds were implanted into the recurrent lesions using the TPS. Within 3 d of 125I seed im-plantation, liposomal paclitaxel was administered by intravenous infusion on day 1 and carboplatin by infusion via the feeding artery of tumor on day 2. Chemotherapy was repeated on a 21-day schedule. Efficacy and complications were evaluated during follow-up. Re-sults:After two cycles of chemotherapy, out of the 25 recurrent lesions that underwent 125I seed implantation, four lesions showed com-plete remission, 14 with partial remission, three with stable disease, and four with progression of disease. The objective response rate was 72%, and the pain relief rate was 82.4%. Karnofsky's performance status scores increased dramatically (P=0.019). The median pro-gression-free survival time was 6.8 months, median overall survival time was 14.2 months, and the 1-year survival rate was 42.9%. He-matologic toxicity and gastrointestinal reactions were the primary adverse conditions. No severe radiation complications and treat-ment-related deaths were observed in all patients. Conclusion:CT-guided 125I seed implantation combined with chemotherapy is active and well-tolerated in patients with recurrent ovarian cancer. This combined treatment cannot only significantly enhance the objective re-sponse rate, but also leads to remarkable improvement in cancer-related symptoms.

Objective To investigate the application value of prophylactic bilateral uterine artery catheterization and embolization in treatment of patients with pernicious placenta previa and accreta.Methods Data of 16 patients with pernicious placenta previa and accreta who underwent prophylactic bilateral uterine artery catheterization and uterine artery embolization and cesarean section were retrospectively analyzed.The amount of intraoperation blood loss,the amount of blood transfusion,cesarean hysterectomy rate,fluoroscopy operative time,radiation dose,complications and neonatal outcome were recorded.Results The technical success rate of the combined treatment was 93.75％ (15/16).The mean amount of blood loss was (1 575.00 ± 1 040.83)ml.The mean amount of blood transfusion was (3.44 ± 2.34)U leukoreduced red blood cells.The mean fluoroscopy operative time and radiation dose before delivery were (0.89±0.24)min and (7.17 ± 2.12)mGy.One newborn was diagnosed as severe asphyxia.The mean Apgar score of another 15 newborns was (9.38± 0.89) at 5 min after birth.One patient underwent hysterectomy due to postpartum hemorrhage complicated with disseminated intravascular coagulation.Buttock pain was found in 2 cases.Conclusion Prophylactic bilateral uterine artery catheterization and embolization can be used for the treatment of pernicious placenta previa and accreta.The combined treatment can control postpartum hemorrhage during placental dissection and reduce transfusion requirements and hysterectomy rate with few minor complications and low radiation exposure dose.

Objective To detect genetic alterations in pleomorphic xanthoastrocytoma (PXA), and to investigate the mechanism of development of this neoplasm. Methods Three patients with PXA were studied. Comparative genomic hybridization (CGH) was performed to study chromosomal imbalances in PXA. Using immunohistochemical analysis, the expression of EGFR was detected in PXA. Results Using CGH analysis, genetic imbalance was detected on at least one chromosome for each case. One patient revealed multiple genetic alterations, including gains of 2p14-pter, 4p15-pter, 7p21-qter, 11q24-qter, 12 and 15q14-qter,as well as losses of 8p11.2-pter, 9p11-p23, 10p12-pter, and 13q14-qter. This patient experienced tumor recurrence and died one year later. Gain on Chromosome 7 and loss on Chromosome 8p were demonstrated in 2 of the 3 patients. Immunohistochemically, no EGFR positive reaction was found in all cases. Conclusion Detection of genetic alterations is very important in understanding the pathogenesis of PXA.

Objective To investigate the clinicopathologic features,diagnosis,differential diagnosis and treatment of sclerosing angiomatoid nodular transformation(SANT). Methods The clinical data,pathologic characteristics,immunophenotype and postoperative follow-up of SANT were analysed. Results There were no specific findings in the clinical manifestations of the 4 cases of SANT.Grossly,the cut surface of the masses was gray-white and vague nodularity was observed.Microscopically,it was characterized by the multinodular angiomatoid appearance in a fibrosclerotic stroma.The nodules were composed of slit-like,sinusoid-like vascular spaces and were interspersed with a population of spindly or ovoid cells.It was revealed by immunohistochemistry that the expression of CD34 in some vessels' endothelial cells was positive,and CD8 was negative.While in another vessels' endothelial cells,CD8 was positive and CD34 was negative.The expression of SMA,Actin,Vimentin,Collage IV and CD68 was positive in all of the 4 cases,while that of CD21,Desmin and NSE was negative.No relapse or metastasis was found during the follow-up.Conclusion SANT is a rarely encountered benign lesion of the spleen,which should be distinguished from the malignant tumor of the spleen.The diagnosis counts on the pathologic and immunohistochemical findings.It could be cured by splenectomy with a favourable prognosis.
