BACKGROUND: Rheumatoid arthritis(RA) is an autoallergic disease,but its immunological pathogenesis has not been completely known. T lymphocytes, especially CD4+ TH1/TH2 cells, may have an important effect in the occurrence and development of RA.OBJECTIVE: To investigate the action of CD4+ TH1 and TH2 cells which separately mediate cellular immunity and humoral immunologic response (respectively) function in the occurrence and development of RA.DESIGN: Case-control, comparative observation.SETTING: Department of Immunology, Medical College of Chinese People's Armed Police Forces.PARTICIPANTS: Totally 15 patients with RA hospitalized in the Department of Internal Medicine of General Hospital of Tianjin Medical University between March 1999 and March 2000 were selected for a RA patient group, consisting of 2 males and 13 females. Of them, 12 patients whose serumal rheumatoid factor (RF)was positive and the three others' was negative. At the same time, 30 healthy individuals from persons receiving health examination in the hospital or from our department were selected for a healthy control group, consisting of 4 males and 26 females. Informed consents were obtained from the participants.peripheral blood mononuclear cells(PBMC) from the two groups of subjects were detected by enzyme-linked immunospot assay (ELISPOT). 200-500 lymphocytes were counted under a normal light microscope, and the perwhich secreted cytokines were detected by ELISPOT, and those which had red spots in their plasma after staining were positive cells. Among them,the cells secreting γ-interferon (IFN-γ) were Tm cells while those secreting interleukin-4 (IL-4) were TH2 cells. 200-500 lymphocytes were counted under a normal light microscope and the percentages of TH1 and TH2 cells square test were used for comparing statistical differences of data between the two groups.MAIN OUTCOME MEASURES: Quantitative analysis of T lymphocyte subsets (including CD3+ T cells, CD4+ T cells and CD8+ T cells) and CD4+ TH1/TH2 cells in peripheral blood from the two groups of subjects.RESULTS: Analysis of the results was from the study on all of subjects percentages of total T cells (CD3+ T cells), CD4+T cells and CD8+F cells in peripheral blood were not significantly different between the two significantly higher in RA patient group than that in healthy control group [(24.44±5.25)%, (14.93±3.82)%, P < 0.05],while in RA patient group the percentage of TH2 cells and ratio of TH1 cells to TH2 cells from peripheral blood were not significantly different as compared with those of control group(P > 0.05).CONCLUSION: Cellular immunologic function mediated by TH1 cells may be associated with the occurrence and development of RA.

Abstract
Transport of filter paper-dried blood spot samples is a critical procedure during the screening of neonatal inherited metabolic diseases, which is of great significance for the screening accuracy. In order to ensure the timing and safety of sample transport, the cold chain positioning system was initiated by Zhejiang Provincial Center for Quality Control of Neonatal Disease Screening since March 2015. Based on the framework of neonatal disease screening information management system, the function of the logistics transport management system was included in this positioning system, with aims to achieve the monitoring and tracking of sample transport processes through real-time positioning of the sample transport box via China Unicom 4G logistics card and global positioning system/BeiDou Navigation Satellite System. The samples are maintained in a transport environment at 2 to 8 °C via the temperature-controlled box made of 5 °C phase-changed cold-stored materials and general packet radio service (GPRS) temperature recorders. The mean pretest turnover duration reduced from 8.44 days to 5.03 days following introduction of the cold chain positioning system, and the percentage of timely sample delivery increased from 31.69% to 77.90%, while the withdrawal rate of unqualified samples reduced from 0.12% to 0.08%. The cold chain positioning system meets the requirements of transport of filter paper-dried blood spot samples, which has a high potential in screening of neonatal inherited metabolic diseases.

Objective:
To evaluate the quality of neonatal screening work for inherited metabolic diseases,to learn the incidence of inherited metabolic diseases in newborns in Zhejiang Province from 1999 to 2018,and to provide scientific basis for formulating policies for control of birth defects.
Methods:
The neonatal screening data for inherited metabolic diseases in Zhejiang Province from 1999 to 2018 were collected from the neonatal disease screening database of Zhejiang Neonatal Disease Screening Center,including congenital hypothyroidism(CH),phenylketonuria/tetrahydrobiopterin deficiency(PKU/BH4D),congenital adrenal hyperplasia(CAH),glucose-6-phosphate dehydrogenase deficiency(G6PD)and other metabolic disorders. The related indicators,such as the screening rate,prevalence rate,recall rate for suspected positive cases,resample rate of unqualified blood slides and rate of delayed blood slides delivery,were calculated to assess the quality of neonatal screening and understand the epidemic situation of inherited metabolic diseases in Zhejiang Province.
Results:
A total of 10 016 839 newborns were screened and the rate rised from 6.46% in 1999 to 100.62% in 2018. The recall rate for suspected positive cases had exceeded 95% since 2007. The rate of unqualified blood tablets was under 1%(0.06% in 2018);the resample rate of unqualified blood slides had exceeded 99% since 2004;the rate of delayed blood slides delivery dropped to 0.19% in 2018. The proportion of newborns screened by tandem mass spectrometry reached 92.75% in 2018. There were 13 664 cases of inherited metabolic diseases confirmed,with 6 723 cases of CH(6.71/10 000),472 cases of PKU/BH4D(0.47/10 000),125 cases of CAH(0.38/10 000),5 644 cases of G6PD(22.19/10 000)and 700 cases of other metabolic disorders(2.13/10 000). The highest prevalence rate of CH,PKU/BH4D,G6PD and other metabolic disorders lay in Lishui,Hangzhou,Ningbo and Quzhou,respectively,which was significantly different in cities(P<0.05).
Conclusion
The neonatal screening rate for inherited metabolic diseases,recall rate for suspected positive cases and resample rate of unqualified blood slides are high,while the rate of unqualified blood slides and delayed blood slides delivery have been kept low in Zhejiang Province. The prevalence of CH is above and PKU/BH4D is below the national average.
