PURPOSE: Polymorphisms of several candidate genes have been studied and associated with the development of chronic obstructive pulmonary disease (COPD). One such candidate is the SERPINE2 (Serpin peptidase inhibitor, clade E member 2) gene. MATERIALS AND METHODS: To assess whether the SERPINE2 gene is associated with COPD in a Chinese Han population. Samples were collected from a Chinese Han population and analyzed for the association of single nucleotide polymor phisms (SNPs) or haplotypes of SERPINE2 gene with COPD in a case-control study. Three SNPs including rs840088 G/A in intron 1, rs1438831 A/G in 5' upstream sequence and rs3795879 G/A in intron 3 were detected using the polymerase chain reaction (PCR)-based restriction fragment length polymorphism technique in 409 COPD subjects and 411 controls. Genotyping of the SREPINE2 polymorphisms at positions rs840088, rs1438831and rs3795879 was performed. RESULTS: We found that none of the rs840088G/A, rs1438831G/A and rs3795879 G/A polymorphisms were associated with the disease. The p-values were 0.630, 0.208 and 0.398 respectively. CONCLUSION: Our data suggested that there was no significant association between SERPINE2 polymorphism and COPD susceptibility in the Chinese Han population.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

Objective:To compare improved microbial assay (IMA) and electrochemiluminescence (ECL) for measuring serum folate, and to investigate the linear or non-linear correlation between the results of the two methods.Methods:This comparative study was conducted in National Health Commission Key Laboratory of Reproductive Health from October 2020 to February 2021, in which the folate concentration of 251 serum samples were measured by IMA and ECL. According to the serum folate concentration, the folate status was divided into sufficient (≥13.5 nmol/L), marginal deficiency (6.8≤serum folate<13.5 nmol/L), and deficiency (<6.8 nmol/L). Pearson correlation analysis and multivariate fractional polynomial (MFP) model were used to evaluate the correlation between the results measured by the two methods. The sensitivity of ECL for detecting folate status were calculated based on the IMA results as the golden standard.Results:The average folate concentrations in serum samples measured by ECL and IMA were (19.8±8.2) nmol/L and (23.0±9.7) nmol/L, respectively ( P<0.001). The Pearson correlation coefficient ( r) of the two methods was 0.894 ( P<0.001), yet the MFP model demonstrated non-linear correlation between the two methods. When the IMA results were≤9.1 nmol/L, the r was 0.070 ( P>0.05); when the IMA results were>9.1 nmol/L, the r was 0.867 ( P<0.001); for non-hemolytic serum samples ( n=221), the r was 0.902 ( P<0.001). Additionally, the sensitivity of ECL detecting folate deficiency was 27.78%, and the sensitivity of ECL detecting folate insufficiency (deficiency and marginal deficiency) was 93.33%. Conclusion:When folate concentrations was>9.1 nmol/L), the results of ECL and IMA were highly correlated; yet the correlation between the two methods was weak at lower folate concentrations, indicating that ECL was not applicable for serum folate measurement among folate insufficiency population.
