Objective:To detect the changes of tumor necrosis factor-α(TNF-α) in nasopharyngeal secretion of patients with nasopharyngeal carcinoma(NPC).Method: The content of TNF-α in nasopharyngeal secretion was determined by radioimmunoassay (RIA) in 20 controls,52 patients with NPC.Result:The average concentrations of TNF-α were (12.95±4.62)pmol/L in control group,(33.68±15.13) pmol/L in NPC group and (64.00±11.57)pmol/L in NPC with necrosis group. The content of TNF-α in nasopharyngeal secretion in control group was lower significantly than that of patients with NPC (P<0.01).Conclusion:The level of TNF-α in nasopharyngeal secretion of NPC patients was higher than that of normal subjects. To detect the content of TNF-α in nasopharyngeal secretion is a useful test for the study and diagnosis of NPC.

Objective To investigate the expression of endothelial protein C receptor (EPCR) and its roles in plasma and placenta of patients with early onset severe preeclampsia. Methods Sixty cases of severe preeclampsia women who delivered in Xuzhou Maternity and Child Health Care Hospital from March 2014 to February 2016, were recruited, which included 30 cases with early onset severe preeclampsia (early onset group, gestational week <34 weeks ) and 30 patients with late onset severe preeclampsia (late onset group, gestational week ≥34 weeks). Thirty cases of healthy late pregnant women at the same period (gestational week≥34 weeks) were selected as control group. Immunohistochemistry SP method was applied to detect the expression of in EPCR placenta. Reverse transcription (RT)-PCR was used to detect the expression of EPCR mRNA in placenta. ELISA method was used to detect the levels of soluble EPCR (sEPCR)level in plasma of the pregnant women of the three groups. Results The expression of EPCR in placenta mainly distributed in the membrane and cytoplasm of placental syncytiotrophoblasts and vascular endothelial cells, a few in the cell nucleus. The expression of EPCR in early onset group(57%, 17/30)was significantly lower than that in late onset group (93%, 28/30; χ2=25.165,P=0.001). The expression of EPCR in late onset group had no significant difference from that in control group (97%, 29/30;χ2=0.540,P=0.910). The expression of EPCR mRNA in placenta of early onset group(0.40±0.07)was significantly lower than that in late onset group(0.91±0.06;t=-30.044,P=0.001), while there was no statistical difference of the expression of EPCR mRNA between the late onset group and the control group (0.92±0.07;t=-0.631, P=0.538). Plasma sEPCR level in early onset group, late onset group and control group were (231 ± 11), (124±6)and(121±4)μg/L respectively, which is higher in early onset group than that in late onset group (t=48.080,P=0.001). There was no statistical difference of plasma sEPCR level between the late onset group and the control group(t=2.534,P=0.100). Conclusions The pathogenesis of early onset and late onset severe preeclampsia may be different. Decreased expression of EPCR in placenta may be associated with the pathogenesis of early onset severe preeclampsia.

Objective:
The Penn Alcohol Craving Scale (PACS) is a five-item, single-dimension questionnaire that is used to measure a patient’s alcohol craving. We sought to develop the Chinese version of the PACS (PACS-C) and assess its reliability and validity.
Methods:
A total of 160 Taiwanese patients with alcohol use disorder were enrolled in this study. The internal consistency and concurrent validity of the PASC-C with the visual analogue scale (VAS) for craving, the Yale–Brown Obsessive Compulsive Scale for heavy drinking (YBOCS-hd), and the Severity of Alcohol Dependence Questionnaire (SADQ) were assessed. The test–retest reliability of the PASC-C was evaluated 1 day after the baseline measurements. Confirmatory factor analysis (CFA) was performed to examine the psychometric properties of the PACS-C.
Results:
The PACS-C exhibited good internal consistency (Cronbach’s α=0.95) and test–retest reliability (r=0.97). This scale showed high correlations with the VAS (r=0.81) and YBOCS-hd (r=0.81 and 0.79 for the obsession and compulsion subscales, respectively), and moderate correlation with the SADQ-C (r=0.47). Furthermore, CFA results revealed that the PACS-C had good fit indices under various models.
Conclusion
The PACS-C appears to be a reliable and valid tool for assessing alcohol craving in patients with alcohol use disorder in Taiwan.

Objective:
The aim of this study is to determine the accuracy of RSI and RFS in the diagnosis of hypopharyngeal reflux (LPR), the scores of RSI and RFS were compared in different age groups. To explore the RSI and RFS scoring thresholds for diagnosis of LPR in different age groups.
Method:
From January 2017 to March 2019, 258 patients with suspected LPR in our hospital outpatient clinic completed the RSI and RFS scales. According to their age, 258 patients with RSI>13 and RFS>7 were selected. They were divided into group A (18-<40 years, n=86), group B (40-<60 years, n=107) and group C (≥60 years, n=65). The diagnosis was confirmed by 24 h pH-metry. The diagnostic rate, RSI and RFS scores were compared among the three groups. ROC curve was used to analyze the optimal thresholds for the diagnosis of LPR by RSI and RFS scores.
Result:
Among the three groups, group C had the highest diagnostic rate(93.85%). There was no significant difference in RFS score among the three groups (P>0.05), RSI score was significantly different (P<0.05), RSI score of group A and group B was higher than that of group C (P<0.05). According to ROC analysis, the best RSI cutoffs for diagnosing LPR in group C was 11, and the area under the ROC curve was 0.866.
Conclusion
The RSI score is a good criterion for the diagnosis of LPR. The diagnostic threshold of RSI in elderly patients is different from that in young patients. For elderly patients, the diagnostic threshold for the recommended RSI score is 11.

Objective To obtain the medical exposure frequency data of residents through a questionnaire survey on mobile phone networks in the community, and to analyze the main influencing factors. Methods A snowball sampling method was used to expand the sampling from medical staff in a county hospital to the community. The questionnaire included personal information such as occupation category, type of medical insurance, and education level as well as basic radiation-related knowledge and medical exposure type and frequency of respondents received in 2021. A logistic regression model was used to analyze the influencing factors of medical exposure. Results A total of 223 respondents were investigated, and 12.56% of them received radiological diagnosis and radiotherapy in 2021. The proportion of males receiving medical exposure was significantly higher than that of females (19.64% vs 10.18%). The likelihood of the person receiving medical exposure increased considerably with age, with the proportion of residents receiving medical exposure at 20, 30, 40, and 50 years of age being 6.25%, 7.95%, 19.23%, and 33.33%, respectively. Of persons who received medical exposure, 57.14% underwent CT scans. Persons participating in the new rural cooperative medical system were likely less to receive radiological diagnosis and radiotherapy than urban workers and residents (OR = 0.55, CI:0.13-2.23, P > 0.05). Conclusion Questionnaire survey in the community can obtain more information about the medical exposure of residents, and age and type of medical insurance are important factors affecting the frequency of medical exposure.

The administration of nanoparticles (NPs) first faces the challenges of evading renal filtration and clearance of reticuloendothelial system (RES). After that, NPs infiltrate through the expanded endothelial space and penetrated the dense stroma of tumor microenvironment to tumor cells. As long as possible to prolong the time of NPs remaining in tumor tissue, NPs release active agent and induce pharmacological action. This review provides a comprehensive summary of the physical and chemical properties of NPs and the influence of various biological factors in tumor microenvironment, and discusses how to improve the final efficacy through adjusting the characteristics and structure of NPs. Perspectives and future directions are also provided.
