Objective To explore the clinical value of plasma(1,3)-β-D-glucan detection(G test)in the diagnosis of invasive fun-gal infections(IFI).Methods The plasma samples were collected in 67 cases of IFI,61 cases of non-IFI and 48 healthy controls from January to September 2013.The level of(1,3)-D-glucan in plasma was detected by the kinetic turbidimetric assay and the opti-mal critical value of the G test was determined by receiver operating characteristic curve(ROC).Results The levels of(1,3)-β-D glucan in the IFI,non-IFI and healthy control groups showed the non-normal distribution.However,the median level of plasma(1, 3)-β-D glucan in the IFI group was 208.00pg/mL,which was significantly higher than 61.30 pg/mL(Z =-5.083,P <0.01)in the non-IFI group and 31.16 pg/mL(Z =-8.288,P <0.01)in the healthy control group.The area under ROC of the G test for diag-nosing IFI was 0.846 and the optimal critical value was 90.49pg/mL.The corresponding sensitivity,specificity,positive and nega-tive predictive values were 86.6%,77.1%,69.9% and 90.3%,respectively;at the same time,which of the fungal culture for diag-nosing IFI were 53.7%,94.5%,85.7% and 61.9% respectively.Conclusion Plasma(1,3)-β-D-glucan detection exhibits the high sensitivity and the better negative predictive value for the diagnosis of IFI.But the false positive results occur at times.It is sugges-ted that the G test can be dynamically conducted combined with the fungal culture for improving the efficiency of IFI diagnosis.

BACKGROUND: Logistic analysis of multi-ordered response-variable is used to probe into from another view the interrelationship between lead content in fetus faeces and neurobehavioral development under exposure to low-level lead in uterus.OBJECTIVE: To probe into multi-factors of neurobehavioral development in neonates and the sensibility.DESIGN: The total score of neurobehavior in neonates was taken as dependent variable and 24 indexes were as independent variables, such as induced factors, lead in umbilicus blood and lead in fetus faeces in questionnaire. Logistic progressive regression of multi-ordered response-variables was used in analysis and corresponding factors were screened at level of P=0.10.SETTING: Wuhan University of Science and Technology, Laboratory Room of Occupation Disease and Epidemic disease in Tongji Medical College of Huazhong University of Science and Technology and Occupation Hospital of China First Metallurgical Construction General Company.PARTICIPANTS: Totally 103 full-month borne and healthy neonates were randomized in Department of Gynecology of one occupation hospital in Qingshan District of New-type Industry Area of Huanhan City from January to October 1999 as the objects. The relatives agreed with topic research and questionnaire investigation and they provided neonatal faeces and received neonatal tests on time.off the umbilicus and preserved in freezing in refrigerator at -4 ℃. The faeces in 24 hours after birth was collected and the lead contents of umbilicus blood and faeces were assayed with graphite furnace atomic absorpBehavioral Neurological Assessment (NBNA) was used in examination on the 3rd day after delivery. Simultaneously, the self-designed questionnaire was adopted in the investigation for parturients. The questionnaire involved other possible factors of neonatal neurobehavioral development, including dependent variables, concerning to states of family, society, environment and health that affected neurological development in neonates and lead contents in umbilicus blood and faeces. Scores of neonatal neurobehavior were taken as response variables. Finally, the corresponding factors were screened.MAIN OUTCOME MEASURES: To screen the factors of neurobehavioral development of neonates.RESULTS: Totally 103 cases entered result analysis. Six factors were selected in the model, named pregnant weeks, the month of drug administration in pregnancy, hemoglobin, emotions in pregnancy, lead level in fetus faeces and drug administration.CONCLUSION: Neonatal neurobehavioral development was related to multiple factors. Good nutrient in pregnancy, long pregnant weeks and good emotions in pregnancy benefit neurobehavioral development of neonates. Drug administration during pregnancy is disadvantageous in neonatal neurobehavioral development, especially the medication at the early phase of pregnancy. The increased lead content in neonatal faeces does not benefit neonatal neurobehavioral development.

Objective To study the difference between intensity-modulated radiation therapy (IMRT) and three dimensional conformal radiation therapy (3D-CRT) for pelvic radiation of post-operative treatment with gynecologic malignant tumor. Methods A prospective investigation study was conducted on 183 patients of post-operative patients with whole pelvic radiation therapy of cervical cancer or endometrial cancer in Zhejiang Cancer Hospital [IMRT group (n=85) and 3D-CRT group (n=98)] from Oct. 2015 to Oct. 2016. The two groups received same dose (45 Gy in 25 fractions). Comparison of two groups with radiation dosimetry:the score according to the Radiation Therapy Oncology Group (RTOG) acute radiation injury grading standards before and after radiotherapy reaction, the score from functional assessment of cancer therapy scale-cervix (FACT-Cx) scale and expanded prostate cancer index composite for clinical practice (EPIC-CP) scale were also analyzed. Results (1) There were no significant effect with age, culture level, family economic condition and ratio of radiochemotherapy between two groups (all P>0.05). (2) Dosimetric comparison for IMRT vs 3D-CRT:the average dose of planning target volume (PTV) decreased(46.1 ± 0.4) vs(46.4 ± 0.5)Gy, V45 dose percentage increased(95.2 ± 1.0)%vs (93.3 ± 2.0)%, intestinal bag dose of V40 decreased(24.4 ± 6.8)%vs (36.5 ± 15.9)%, rectal V40 dose percentage decreased(73.9 ± 12.3)%vs (85.4 ± 8.4)%, and lower rectal V45 dose percentage(32.8 ± 13.4)%vs (71.5 ± 13.7)%, bladder V40 dose percentage decreased(55.5 ± 13.0)% vs (84.4 ± 13.0)%. Bone marrow V20 lower:(67.9 ± 5.4)% vs (79.5 ± 6.6)%, V10 lower:(82.1 ± 6.0)% vs (86.3 ± 6.6)%; there were significant differences (all P<0.05). There was no significant difference between the dose of V45 in the intestinal pouch and bladder (P>0.05). (3) Acute radiation injury classification for IMRT vs 3D-CRT:big or small intestine:Ⅱ-Ⅲreaction [13%(11/85) vs 24% (24/98); χ2=3.925, P=0.048], there was significant difference. Bladder: Ⅲ reaction [19% (16/85) vs 26% (25/98); χ2=1.171, P=0.279], there was no significant difference. Radiochemotherapy of bone marrow suppression:Ⅲ-Ⅳreaction (14/20), the incidence rate [26%(14/54) vs 31%(20/65);χ2=0.339, P=0.562], the difference was not statistically significant. (4) Quality of life scale by FACT-Cx scale in IMRT vs 3D-CRT:there were no significant difference before radiotherapy (82 ± 16 vs 85 ± 16;t=1.279, P=0.203), while there was significant difference after radiotherapy (76 ± 14 vs 71 ± 18;t=-2.160, P=0.032). EPIC-CP scale score:before radiotherapy they were (16±7 vs 15±6;t=-0.174, P=0.862) ,but after radiotherapy (18±7 vs 22± 7; t=3.158, P=0.002), there was significant difference between them. Before and after radiotherapy, the increased EPIC-CP scale of the IMRT group vs 3D-CRT group were 3 ± 4 and 6 ± 4, the 3D-CRT group was significantly higher, the difference was statistically significant (t=5.500, P=0.000). Conclusion IMRT has shown that there are a significant benefit for the post-operative patients with cervical cancer and endometrial cancer compared to 3D-CRT.

Objective To explore the function of infliximab in inducing remission in Crohn's disease and the effect of the inducing remission were followed up. Methods Ten patients with Crohn's disease received a infliximab, 5-aminosalicylic acid (5-ASA) and Azathioprine (AZA) therapy for inducing and maintenance remission. Crohn' s disease activity index (CDAI), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), alanine aminotransferase (ALT), apartate aminotransferase, (AST), total bilirubin (TBil), conjugated bilirubin, (CB), creatinine (Scr) were evaluated at week 0, 10, 22 and 50. Simple endoscopic score for Crohn's disease (SES-CD) were evaluated at week 0, 10 and 50. Adverse reactions were also evaluated. Results At week 10, all patients achieved remission. The indicators of CDAI, CRP, ESR and SES-CD were significantly declined than those at week 0 (P＜0.01). The follow-up was terminated in one patient due to the relapse at week 30. At week 50, the indicators of CDAI, CRP, ESR and SES-CD in six patients a little bit increased compared with those at week 10, but no statistic significant (P=0. 2001、0. 0600、0. 1328、0. 4230 respectively), but significantly declined compared with those at week 0 (P =0.0005、0.0087、0.0054、0. 0163 respectively). No severe adverse reaction was observed in all patients.Conclusions Infliximab showed an exact efficacy in inducing remission in Crohn's disease. And 5-ASA and AZA were effective for maintenance remission in part of the patients after infliximab induced remission.

ObjectiveTo understand the experience， knowledge and attitudes of e-cigarette users in Shanghai， and to provide evidence for the development of intervention programs for e-cigarette use. MethodsThe Respondent-Driven Sampling （RDS） method was used to recruit 40 e-cigarette users for qualitative interviews from November 2020 to February 2021. NVivo （11.0） software was used to code interview records， and the thematic pattern and relationship analysis were conducted. ResultsIn terms of the reasons and user experience of e-cigarette use， most respondents used e-cigarettes for the first time after recommendation of friends； The reasons for the current use of e-cigarettes focus on the subjective feelings generated by the use of e-cigarettes （easy to use， replacing traditional tobacco， and having many flavors）. Compared with traditional tobacco use， respondents said e-cigarettes tasted good and had no physical impact （they could be used all the time without making them uncomfortable）. In terms of the awareness of e-cigarette use related knowledge， the respondents' opinions on whether e-cigarettes caused health risks were mostly based on their own experience of using them， and they said it was difficult to identify real information online. As for whether they were interested in relevant knowledge， most respondents said they wanted to learn about the professional knowledge related to e-cigarettes. Regarding the attitude related to the use of e-cigarettes， most respondents believed that e-cigarettes are addictive， e-cigarettes are not a safe alternative to traditional tobacco， ande-cigarettes couldn't help them quit smoking. Three out of ten respondents said they supported including e-cigarettes in the Regulation on Smoking Control in Public. ConclusionThere are certain characteristics of e-cigarette users' feelings， related knowledge and attitude towards e-cigarette use that should be targeted to carry out publicity， education and intervention.
