Objective:To investigate the effects of sign-contract services on hypertension patient disease control and the satisfaction of medical staff. Methods:a face-to-face questionnaire survey was conducted among hypertension patients selected from 20 primary health centers in 10 provinces in China. Results:This paper collected 1 ,881 valid questionnaires, and the average age of the population was 65. 72 ± 10. 88. Respondents that received sign-contract services accounted for 53. 88%, and there was no difference between patients who signed the service contract and who did not in terms of demographics. In self-reporting of blood pressure controls, respondents who signed the service contract, aged 40~50 years old, enjoyed the free medical care, preferred to seek medical services from primary a-gencies ( i. e. community health centers and township hospitals) for minor illnesses, controlled their blood pressure better ( P<0. 05 ) . Respondents enjoyed the civil resident medical insurance, preferred to seek medical care from community health centers for minor illnesses and signed the service contract were more likely to be satisfied with their medical practitioner (P<0. 05). After adjusting for age, gender, education level, medical insurance style, patient willingness to seek medical care for minor illnesses, signing service contracts was found to be an independent factor both associated with blood pressure self-control and attitudes towards medical service providers, with the odds ratio of 3. 007 (95%CI:2. 572 -3. 517) and 1. 814 (95%CI: 1. 563 -2. 105) respectively. Conclusion: Contracts are correlated with blood pressure control and satisfaction toward medical practitioners, which means that patients who signed the service contract control their blood pressure better and are more satisfied with their medical deliverers.

[Objective]To present a case of complete androgen insensitivity syndrome (CAIS) coexisting with Müllerian duct remnants (MDR) and to review previous reports in the literature to enhance the understanding of the clinical manifestations and pathophysiology of CAIS.[Methods]The study aimed to diagnose complete androgen insensitivity syndrome (CAIS) by conducting physical examinations,chromosomal analysis,whole exome sequencing,laboratory tests including follicle-stimulating hormone (FSH),luteinizing hormone (LH),total testosterone,estradiol,anti-Müllerian hormone (AMH),inhibin B,dehydroepiandrosterone sulfate (DHEAS),androstenedione,17-hydroxyprogesterone,and imaging studies such as pelvic ultrasound and pelvic magnetic resonance imaging (MRI). Laparoscopy revealed the presence of Müllerian duct structures. Additionally,the study reviewed similar cases of CAIS combined with Müllerian duct remnants reported in the literature.[Results]The child presented with female phenotype,elevated levels of FSH,LH,and testosterone. Pelvic MRI showed bilateral cryptorchidism without visible uterus or fallopian tubes. The chromosomal karyotype was 46,XY,and whole exome sequencing identified a pathogenic variant in the androgen receptor (AR) gene,c.2359C>T (p.Arg787*). No abnormalities were found in the AMH and AMHR2 gene tests. Laparoscopic exploration revealed underdeveloped testes and an underdeveloped uterus. Pathology showed the presence of fallopian tube-like structures next to the testicles. A total of 11 cases with genetically confirmed diagnosis of CAIS coexisting with MDR were retrieved from the database. The findings suggest that the initial clinical presentation,biochemical data,and gonadal pathology of CAIS with MDR are similar to those without MDR.[Conclusion]The study reports a patient with CAIS coexisting with MDR,which broadens the clinical spectrum of CAIS and provides a perspective for basic research on Müllerian duct regression that is independent of the AMH-AMHR2 signaling pathway.

Biological desulfurization is a process in which sulfur compounds are removed from gas and oil using microorganisms. It is a simple process that has mild operating conditions, high desulfurization efficiency, low energy consumption and less environmental pollution. However, there is still a lack of simple and efficient analytical methods for quantitatively analyzing the sulfur compounds in the biological desulfurization process. In order to solve this problem, the analytical method for the simultaneous determination of sulfite, thiosulfate and sulfide in biological desulfurization solutions by pre-column fluorescence derivation using high performance liquid chromatography (HPLC) was developed. The standard curves of sulfur species in this analytical method had good linear relationships with correlation coefficients of 0.999 5, 0.999 7, and 0.999 7 for sulfite, thiosulfate and sulfide, respectively. The detection limits of these sulfur compounds were 0.000 6, 0.000 7 and 0.001 1 μmol/L; the range of recovery rates were 98.17 to 101.9%, 100.9 to 102.6%, and 101.1 to 104.2%; which had good repeatability and stability. The analytical method was simple, efficient and accurate, and could be used to simultaneously determine the sulfur compounds in different biological desulfurization systems.
