Objective To improve the diagnosis and management of parapharyngeal space(PPS)neoplasms. Methods Records of 85 patients with PPS neoplasms operated in 11 years were reviewed with regard to presenting signs and symptoms,histological characteristics,imaging technique,surgical approach and postoperative complica- tions.Results Benign rumors were found in 77 cases and malignant tumors were founded in 8 cases.Forty-one tu- mors originated from salivary glands;neurogenic tumors were found in 36 patients and 8 patients with tumors in oth- er organs.All were treated by surgical operation:the trans-eervical approach was used in 76 cases,tans-oral in 6 cases and the combined transoral-cervical approach in 3 cases.The complications after operation were facial nerve palsy(4 cases),hypoglossal nerve paralysis(2 cases)Horner syndrome(2 cases),vocal cord paralysis(2 cases),thyroid gland fistula(1 case),infects(1 case)and difficulty in breathing(1 case).Conclusion Tumors originated from salivary glands were the most common neoplasms in the primary parapharyngeal space neoplasms,and neurogenic tumors fol- lowed.High-resolution computed tomography or magnetic resonance imaging was essential for diagnosis and presurgi- cal planning.The transcervical approach was the preferred procedure for PPS tumors.

It has been 50 years since the discovery of thyrotropin receptor autoantibody (TRAb). Advances in the knowledge of thyrotropin receptor ( TSHR) structure and function, combined with the elucidation of TSHR signaling and TSHR-autoantibody interaction have greatly facilitated our understanding of TRAb and their clinical applications. Measurement of TRAb activity plays an important role in the diagnosis of Graves' disease ( GD) and Graves' opthalmopathy. It has also been well recognized that TRAb is an effective predictor of GD relapse or remission after antithyroid drug and radioactive iodine treatment. TRAb test is of particular help in pregnant women and lactating mothers with recent iodine load, where radioactive iodine or technetium tests are contraindicated. In addition, it is useful in the diagnosis and differential diagnosis of fetal and neonatal hyperthyroidism as well as some rare forms of thyrotoxicosis in clinical practice. Accumulating evidence also indicates the possible correlation between thyroid cancer occurring in GD patients with positive TRAb and adverse outcomes. However, further innovation and standardization of TRAb tests are required to help pave the way for clinical applications.

Gray relational analysis is employed to analyze the effects of nano-drug features on phagocytosis of macrophages, including zeta potential, shape factor and scale size of drug particle, the correlation among such factors and macrophage cell is calculated. The results showed that the internalization processe is affected significantly by the zeta potential of the drug in the process of phagocytosis of macrophages, followed by the impact particle shape, and the effect of particle scale behaves relatively small.

Objective To observe the influence of trastuzumab on DNA break repair and Her-2 nuclear import after radiation in breast cancer cell line SKBR3,and discuss the radiosensitivity mechanism of trastuzumab.Methods Clone formation assay was used to analyze the difference of survival fractions between radiation group and radiation plus trastuzumab group.Confocal microscopy was applied to observe the influence of trastuzumab in the nuclear import process of Her-2 and the expression of γH2AX after radiation,which is considered as the marker of DNA double strand break.Western blotting was used to detect the expression of Her-2 and DNA-PKcs in nuclei after radiation.Results The result of clone formation assayshowed that the SF2 in radiation group was 0.547±0.046 and 0.321±0.022 in the radiation plus trastuzumab group were significantly decreased,the results of confocal microscopy showed that trastuzumab postponed the nuclear import process of Her-2 (52.80±19.74 in radiation group,21.41±10.55 in the radiation group),and increased expression of γH2AX after radiation (85.40±25.63 in radiation group,18.53±44.32 in the radiation group),and western blotting revealed trastuzumab reduced the expression of Her-2,DNA-PKcs in nuclei.Conclusion Trastuzumab can inhibit the radiation induced nuclear import of Her-2,and decrease Her-2,DNA-PKcs in nuclei to increase the DSB on early stage after radiation.

Objective To evaluate the efficacy of port catheter system(PCS)placement in pulmonary artery via percutaneous subclavicle vein treatment for multiple metastatic tumor in the two lungs and discuss the PCS technique.Methods Fifteen multiple metastatic tumor patients(13 hepatocellular carcinomas,one mandible grand adenocarcinoma,one oral bottom squamous carcinoma)were carried out with pulmonary artery PCS placement by way of percutaneous subclavicle vein.FPA/FPM/GP chemotherapy scheme were introduced every 4～6 weeks.Results The success rate of PCS placement technique was 93.3%(14/15).One case failed.Percutaneous subclavicle veins were performed 14 cases in right side and 1 in left one.Following up 2～43 months,2～7 chemotherapy cycles(mean 5 cycles)were accomplished,and the clinical CR and PR were achieved in 1 and 3 cases respectively with clinical efficacy rate 28.6%(4/14).Major side reaction was late wound healing in 1 case.Conclusion PCS placement in pulmonary artery treatment for multiple metastatic tumor in the two lungs is effective,and mastering operation technique is the key for increasing operation suc- cess rate.

This study examined the radiation-induced ERBB2 nuclear transport in the BT474 breast cancer cell line and the relationship between caveolin-1 and radiation-induced ERBB2 nuclear transport. The BT474 cells were treated with herceptin (200 nmol/L), PP2 (a caveolin-1 inhibitor, 100 nmol/L) and irradiation combined or alone. Confocal microscopy was used to observe the nuclear import of ERBB2 and caveolin-1 after irradiation. Western blotting was employed to detect the expression of ERBB2, caveolin-1 and DNA-PKcs after irradiation, and immunoprecipitation to identify the ERBB2 and caveolin-1 complex before perinuclear ERBB2 localization. Confocal microscopy showed the transport of ERBB2 and caveolin-1 from the cell membrane to the nucleus 15 min after irradiation and the proteins accumulated at the perinuclear region within 45 min. Western blotting revealed that the expression levels of ERBB2, caveolin-1 and DNA-PKcs were increased after irradiation and reached a peak 45 min later. Both herceptin and PP2 treatments were found to decrease ERBB2 expression. An immune complex composed of ERBB2 and caveolin-1 was found in the herceptin group after irradiation. It was concluded that after irradiation, ERBB2 may be transported from the cell membrane to the nucleus and activate DNA-PKcs to trigger DNA double-strand break (DSB) repair; caveolin-1 may participate in this process. Treatments involving the downregulation of caveolin-1 may increase the radiosensitization of breast cancer cells.

[Summary] To determine how endocrinologists in China access and treat patients with Graves' orbitopathy (GO) and gain insight on how to make the management of this disease more uniform and standardized in the context that management of GO continues to be challenging.Based on the questionnaire used in the European survey on GO,a questionnaire in Chinese was drafted and circulated to the members of Chinese Society of Endocrinology (CSE).There were a total of 124 valid responders.The majority (94.4％) of the responders believe that a muhidisciplinary approaches for GO management is valuable.Over 80％ of the participants advocated the evaluation of exophthalmometry,vision,visual fields by perimetry,eye movements,fundoscopy,TSH receptor antibodies,thyroid function,and ultrasound.Steroids were preferred as the first-line therapy by 92.7％ of responders,among them,59.7％ choose intravenous route.The treatment strategy for GO with intravenous glucocorticoids therapy still remains debated.Antithyroid drugs were the most common choice (72.6％) for first-line therapy of thyrotoxicosis.Treatment options for GO were very similar among Chinese,Latin-American,and European responders,though radioactive iodine and surgical treatment were more often indicated in China.The appropriate treatment of the patient with GO is controversial even amongst thyroid specialists.Further training of clinicians,easier access of patients to specialist multidisciplinary centres,and the publication of practice guidelines may help improving the management of this condition in China.

Objective To explore the predictive value of soluble growth STimulation expressed gene 2(sST2) on major adverse cardiovascular events(MACE) of acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI).Methods The study included 148 patients with first episode of AMI admitted from January 2015 to May 2016 in the heart center of the First Hospital of Lanzhou University.Serum sST2 level before PCI was tested and all patients were followed up clinically for 6 months after PCI.Results 1.MACEs were found in 23 patients during follow up.The sST2 leveles were significantly higher in patients with MACEs than the non-MACE group [(44.50 ±5.32) ng/ml vs.(23.59±1.15) ng/ml, P=0.001].Pearson correlation analysis showed that serum sST2 were positively correlated with MACE and type Ⅲ procollagen amine terminal peptide (PⅢNP) but was not correlated with NT-proBNP.2.Serum sST2 found to be correlated with the body mass index, blood pressure, triglycerides, aspartate aminotransferase, left ventricular end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF).3.The area under the ROC curve of sST2 to predict the occurrence of MACE after PCI was 0.787 which was higher than that of NT-proBNP.The area under curve of sST2 combined with NT-proBNP was 0.820.4.The survival rate of patients with serum sST2 level ≤29 ng/ml was higher than patients with sST2>29 ng/ml in 6 months after PCI.Conclusions sST2 is affected by a variety of factors.sST2 combined with NT-proBNP can improve the predictive value of MACE after PCI, and higher the level of sST2, higher the mortality rate in 6 months after PCI.

Abstract?AIM: To compare the changes in epithelial thickness profile following TransPRK and Epi-LASIK for myopia.? METHODS: In this prospective non -randomized controlled study, 76 right eyes of 76 myopic patients with the spherical equivalent refraction -1.25 to -6.00D were included under the informed consent. The eyes were divided into TransPRK group for 43 eyes and Epi-LASIK group for 33 eyes. Epithelial thickness was measured using spectral-domain optical coherence tomography at different corneal zones ( central, 2mm; paracentral, 2-5mm;and mid-peripheral, 5-6mm) preoperatively and at 1, 3, and 6mo postoperatively. The results were compared between the two groups.?RESULTS: The epithelium were thicker at 3 and 6mo after surgery compared to preoperative measurements in the two groups (all P<0.05).In TransPRK group, the epithelial thickness at 3 and 6mo demonstrated a negative meniscus-like lenticular pattern with lesser thickening centrally and progressively great thickening centrifugally (F3mo =-2.687,P=0.027;F6mo =-2.908,P=0.000).No statistically significant change was detected among the three zones in Epi-LASIK group (F=1.365, P=0.237). The epithelial thickness was thicker in the TransPRK group compared to the Epi-LASIK group mid-peripherally ( P<0.05) .? CONCLUSION: Significant epithelial thickening was observed after TransPRK and Epi-LASIK.It was showed a lenticular change with more thickening mid-peripherally after TransPRK than Epi -LASIK. Wound healing and inflammation may account for differences in the effect on epithelial thickness change by both surgeries.

AIM: To observe the clinical efficacy and safety of vincamine sustained release capsules on non- arteritic anterior ischemic optic neuropathy ( NAION) . · METHODS: Patients who were diagnosed with monocular onset NAION in acute stage from January to September 2015 were divided into two groups. Routine treatment such as steroid pulse therapy and neurotrophic treatment were given to all the patients. Vincamine was added to the treatment group patients with 30mg twice a day for 3mo. The best corrected visual acuity ( BCVA), mean deviation ( MD) of visual field, retinal nerve fiber layer ( RNFL ) , ganglion cell complex ( GCC ) , pattern visual evoked potential ( PVEP ) and OCT results were analyzed before and after the treatment. ·RESULTS:Totally 42 eyes of 42 patients were enrolled in our study. There were 27 patients in the treatment group, aged from 33 to 79 years old, the average value was 55. 55± 11. 83 years old. The control group has 15 patients, aged from 40 to 70 years old, the average value was 55. 71 ± 10. 06 years old. There were no statistical differences between the two groups in the baseline. After 3mo of the treatment, MD value of the two groups were lower compared with the baseline, the difference was statistically significant in the treatment and control group respectively (t= 2. 342, 2. 692; P = 0. 027, 0. 041). The difference of PVEP amplitude and potential of the two groups before and after the treatment were not statistically significant. The thickness of retinal nerve fiber layer and the ganglion cell complex were all lower than the baseline, and the difference was statistically significant (P<0. 001). The treatment of the two groups were both effective, the treatment group has better treatment effect than the control group. Adverse events related to the treatment of vincamine had not been found. ·CONCLUSION:Vincamine is helpful in the treatment of non-arteritic anterior ischemic optic neuropathy.
