Objective To explore the related factors with plasma neuropeptide Y in 180 normal healthy people by stepwise regression analysis. Methods Right ventricular end-diastolic diameter(RVDD),inter-ventricular septum end-diastolic thickness(IVST),left ventricular end-diastolic diameter(LVDD),left ventricular posterior wall end-diastolic thickness(LVPWT),ejection fraction(EF),strole volume(SV),cardiac output(CO),cadiac output index(CI),stroke volume index(SI) and plasma neuropeptide Y were measured respectively by echocardiography and immunoradioassay in all subjects. In addition,we examined the height,weight,blood pressure,heart rate and subcutaneous fat thickness in every subjects. Results The plasma neuropeptide Y wasn't significant difference in different gender and age(P≥0.05). The plasma neuropeptide Y of healthy population was normal distribution and the 95% of confidence interval 70.27 to 190.61,and 99% of confidence interval was 51.23 to 209.65. Conclusion The EF,height,LVST,diastolic blood pressure,CO,SV and subcutaneous fat thickness were the major related-factors of neuropeptide Y in plasma. The EF and height were negatively correlated with plasma neuropeptide Y,and other five factors were postive correlated with it.

Objective:To compare the performance of the severity-of-illness score for toxic epidermal necrolysis (SCORTEN) and ABCD-10 (age, bicarbonate, cancer, dialysis, 10% body surface area) scoring systems in predicting death in patients with Stevens-Johnson syndrome (SJS) /toxic epidermal necrolysis (TEN) .Methods:Clinical data were collected from 85 patients with SJS/TEN who were hospitalized in Sichuan Provincial People′s Hospital from January 2010 to April 2021, and retrospectively analyzed. The predicted mortality and actual mortality were compared at each score level of SCORTEN and ABCD-10. The receiver operating characteristic (ROC) curve and Hosmer-Lemeshow goodness-of-fit test were used to evaluate the predictive power and calibration of SCORTEN and ABCD-10 on mortality.Results:Among the 85 patients, 37 were males and 48 were females, and their ages were 52.36 ± 19.31 years (range, 14 - 88 years) . There were 61 cases of SJS, 6 of SJS/TEN overlap, and 18 of TEN. Ten patients died in hospital and the fatality rate was 11.76%. Among the SCORTEN and ABCD-10 components, age > 40 years or ≥ 50 years, epidermal exfoliation > 10% body surface area on the 1st day after admission, heart rate > 120 beats per minute, serum urea nitrogen level > 10 mmol/L and serum bicarbonate level < 20 mmol/L were significantly correlated with death ( χ2 = 4.46, 6.18, 25.50, 15.13, 7.59, 8.38, respectively, all P < 0.05) , while malignancies, serum glucose level > 14 mmol/L, and pre-hospital dialysis were not significantly correlated with death ( χ2 = 0.35, 0.10, 1.38, respectively, all P > 0.05) . There were no significant differences between the predicted mortality and actual mortality at every score level of SCORTEN and ABCD-10 (all P > 0.05) . The ROC curve showed that both SCORTEN and ABCD-10 had good predictive power for death (areas under the curve: 0.874 and 0.867, 95% CI: 0.758 - 0.990, 0.773 - 0.962, respectively) , but the model goodness-of-fit of SCORTEN was superior to that of ABCD-10 ( P = 0.944, 0.048, respectively) . Conclusion:Both SCORTEN and ABCD-10 scoring systems could accurately predict mortality of SJS/TEN patients at early stage, but SCORTEN showed more favourable predictive power and calibration.

Objective To investigate the incidence and the types of gene mutations of α-thalassemia in the child-bearing pop-ulation of Conghua District,Guangzhou.Methods Blood samples from 24 083 people of childbearing age were screened by blood cell analysis and hemoglobin electrophoresis,α-globin gene variation was detected by GAP-PCR and PCR reverse dot blot in the positive cases,and 17 common β-globin gene mutations were detected by PCR reverse Dot blot.Results A total of 2 596 cases of α-thalassemia gene abnormality were detected by gene identification,and the abnormal rate was 10.78%.A sum of 170 cases(0.71%)had a compound mutation of α-β gene.There were 2 550 cases(98.23%)of deletion and 46 cases(1.77%)of non-deletion in the mutant genes.There were 14 types of gene mutation,including 5 types of HbH disease(with--SEA/-α3.7 primarily),4 mild types(with 68.61%of--SEA/αα genotype),and 5 quiescent types(the top two genotypes were-α3.7/αα and-α4.2/αα).A total of 23 types of αβ complex gene mutation were detected,and the top six types were--SEA/βCD41-42,-α3.7/βCD41-42,--SEA/β654,--SEA/-28,-α3.7/β654 and-α3.7/βCD17,which accounted for 75.27%of all the complex types.Conclusion The gene abnormality rate of α-thalassemia in Conghua District of Guangzhou City was high.The gene mutation type and constitu-ent ratio,which have their own characteristics,is a special region of α-thalassemia.

AIM: To analyze the research status and future development trends of intermittent exotropia(IXT)by bibliometric study.METHODS: Bibliometrics methods were used and the related literatures in the Web of Science Core Collection(WoSCC)database from 2003 to 2022 were retrieved. CiteSpace6.2.R2 software was used to conduct visualized analysis of publications of one year, countries, institutions, journals, authors, references and keywords.RESULTS: A total of 620 literatures on IXT were retrieved from 2003 to 2022, and there has been a progressive increase in the number of publications. South Korea and the United States, Mayo Clinc and Holmes JM were the most productive and impactful country, institution and author, respectively. The Journal of American Association for Pediatric Ophthalmology and Strabismus(J AAPOS)published the most manuscripts(78 publications). The keywords with the strongest citation burst were surgery, epidemiology, alignment and recurrence.CONCLUSION: Visualized analysis conducted by CiteSpace software could objectively show the quantity changes and distribution of literatures on IXT from 2003 to 2022. Furthermore, the research hotspot of IXT has gradually shifted from surgery and epidemiology to fusion and recurrence.

Objective To understand the correlation between atmospheric particulate matter and confirmed cases of influenza in Pudong New Area, Shanghai, and to provide a basis for formulating relevant control measures. Methods The meteorological factors (average temperature, relative humidity, and atmospheric pressure), atmospheric pollutants (PM_2.5, PM₁₀, SO₂, NO₂, CO, and O₃) and confirmed cases of influenza of different ages and genders from January 1, 2014 to December 31, 2018 were collected. Data was fitted to a generalized additive model of Poisson distribution to assess the correlation between atmospheric particulate matter (PM_2.5, PM₁₀) and the number of confirmed cases of influenza. Results There was a correlation between atmospheric particulate matter and the number of confirmed cases of influenza in Pudong New Area. For each increase of 10 μg/m³ in the concentration of the two types of particulate matter, the confirmed cases increased by 0.638% (95%CI: 0.413%~0.864%), and 0.520% (95%CI: 0.324%~0.715%), respectively, when the lag was 0-7d (lag07). People of different ages and genders were affected by atmospheric particulate matter differently. After incorporating the effects of SO₂, NO₂, CO, and O₃ in the multi-pollutant model, the effect of atmospheric particulate matter on the number of influenza cases had changed. Conclusion The increase of atmospheric particulate matter (PM_2.5, PM₁₀) concentration increased the number of confirmed cases of influenza in Pudong New Area.

Retrograde adeno-associated viruses (AAVs) are capable of infecting the axons of projection neurons and serve as a powerful tool for the anatomical and functional characterization of neural networks. However, few retrograde AAV capsids have been shown to offer access to cortical projection neurons across different species and enable the manipulation of neural function in non-human primates (NHPs). Here, we report the development of a novel retrograde AAV capsid, AAV-DJ8R, which efficiently labeled cortical projection neurons after local administration into the striatum of mice and macaques. In addition, intrastriatally injected AAV-DJ8R mediated opsin expression in the mouse motor cortex and induced robust behavioral alterations. Moreover, AAV-DJ8R markedly increased motor cortical neuron firing upon optogenetic light stimulation after viral delivery into the macaque putamen. These data demonstrate the usefulness of AAV-DJ8R as an efficient retrograde tracer for cortical projection neurons in rodents and NHPs and indicate its suitability for use in conducting functional interrogations.
