Objective:
Schizophrenia is a common mental disorder, and mitochondrial function represents a potential therapeutic target for psychiatric diseases. The role of mitochondrial metabolism-related genes (MRGs) in the diagnosis of schizophrenia remains unknown. This study aimed to identify candidate genes that may influence the diagnosis and treatment of schizophrenia based on MRGs.
Methods:
Three schizophrenia datasets were obtained from the Gene Expression Omnibus database. MRGs were collected from relevant literature. The differentially expressed genes between normal samples and schizophrenia samples were screened using the limma package. Venn analysis was performed to identify differentially expressed MRGs (DEMRGs) in schizophrenia. Based on the STRING database, hub genes in DEMRGs were identified using the MCODE algorithm in Cytoscape. A diagnostic model containing hub genes was constructed using LASSO regression and logistic regression analysis. The relationship between hub genes and drug sensitivity was explored using the DSigDB database. An interaction network between miRNA-transcription factor (TF)-hub genes was created using the Network-Analyst website.
Results:
A total of 1,234 MRGs, 172 DEMRGs, and 6 hub genes with good diagnostic performance were identified. Ten potential candidate drugs (rifampicin, fulvestrant, pentadecafluorooctanoic acid, etc.) were selected. Thirty-four miRNAs targeting genes in the diagnostic model (ANGPTL4, CPT2, GLUD1, MED1, and MED20), as well as 137 TFs, were identified.
Conclusion
Six potential candidate genes showed promising diagnostic significance. rifampicin, fulvestrant, and pentadecafluorooctanoic acid were potential drugs for future research in the treatment of schizophrenia. These findings provided valuable evidence for the understanding of schizophrenia pathogenesis, diagnosis, and drug treatment.

Objective To develop a novel colorimetric method for detecting the tumor biomarker vascular endothelial growth factor (VEGF) based on aptamer and magnetic beads.Methods The capture aptamer was hybridized to urease functionalized single-stranded DNA (ssDNA) and immobilize on the surface of magnetic beads by specific biotin-avidin binding.In the presence of VEGF,aptamers bound to VEGF to form a specific stem-loop structure to release the urease functionalized ssDNA.After separation,the supernatant was transferred to a tube and urea and phenol red were added.Urease hydrolyzed urea to produce ammonia to cause an increase of the pH value and a color change of phenol red.The results were inspected with either the naked eyes or by a UV spectrophotometer.Results Under optimized conditions,the detection system showed a good linear relationship for VEGF detection in the range of 0.1 to 10 pmol/L with a detection limit as low as 0.06 pmol/L.The results of VEGF detection in the serum of patients with lung cancer were consistent with those using an ELISA Kit.The results of examination of 10 serum samples with this aptamer-based method and ELISA kit showed that the accuracy of this method was 90%.Conclusion This aptamer-based system provides an simple and convenient method for VEGF detection with a high sensitivity and selectivity.

Objective:
To analyse the construction and use of primary and secondary school clinics in China, and to provide the reference for the construction and management of infrastructure of the clinics of primary and secondary schools.
Methods:
By using stratified cluster random sampling method, 873 primary and secondary schools were selected in east, middle and west of China as research objects to describe the construction and management of the clinics of primary and secondary schools. Regional differences were analyzed by statistical method.
Results:
Among the 873 schools investigated, 294 (33.7%) schools had clinics, 177 (20.3%) schools had healthcare rooms, and 402 (46.0%) schools had no clinics or healthcare rooms. Among the 294 clinics, only 56 (19.0%) schools had medical institution licenses; 73 (24.8%) schools had a construction area of ≥40 square meters; 135 (45.9%) schools had legal clinics, and 38 (12.9%) schools was a disinfection supply room, 2 (<0.01%) schools had a laboratory, 165 (56.1%) schools was not independent between the departments; the overall standard school clinics construction rate was less than 5%. There were differences in the construction of clinics and healthcare rooms in the east, middle and west parts of China (χ2=237.33, P<0.01). Equipment allocation of the country's primary and secondary schools’ clinics were uneven among regions. The normal allocation rates of thermometer, visual acuity chart and lever weight scale were 96.6%, 83.0% and 75.9%, respectively, and the allocation rate of ultraviolet lamp was 66.7%. Less than 50% syringes and high-pressure sterilizers could be used normally. The reasons for the failure to provide health services in clinics was the absence of equipment and space, which account for 43%.
Conclusion
The construction of school clinics and healthcare rooms in China is insufficient, and regional differences are obvious, especially in the west. It is necessary to strengthen regional construction, allocate and use the equipment reasonably.

Objective:To analyze the status quo, trend and influencing factors of patient satisfaction in tertiary maternity and child hospitals in China.Methods:Based on the survey results of five round third-party evaluations of the China Healthcare Improvement Initiative from 2016 to 2021, descriptive trend analysis was conducted on the satisfaction index in tertiary maternity and child hospitals, and the influencing factors of satisfaction were analyzed based on the results of the fifth evaluation.Results:Compared with the first round, the overall patient satisfaction in tertiary maternity and child hospitals in the fifth round was improved(inpatient: from 95.7% to 98.0%; outpatient: from 87.8% to 94.9%). Outpatient satisfaction varied significantly among gender, hospitals of different types, education level, types of treatment, medical insurance and doctors′ titles( P<0.05). Outpatient satisfaction in local hospitals was 1.502 times higher than that in hospitals under the National Health Commission. The satisfaction of referrals was 0.259 times lower than that of patients who were admitted directly. Inpatient satisfaction varied significantly among department, hospitals of different regions, household registration type and whether the admission was delayed due to the COVID-19 epidemic( P<0.05). The satisfaction of inpatients in medical ward and surgical ward was respectively 0.202 and 0.298 times lower than that of inpatients in pediatric ward. Inpatient satisfaction at the central regions was 3.311 times higher than that at the eastern regions. Conclusions:The overall patient satisfaction in tertiary maternity and child hospitals in China is improving. In the future, we should pay more attention to the hospital environment, humanistic care and other non-medical service dimensions with low satisfaction, so as to further improve the medical experience of patients in maternity and child hospitals.

Objective:To investigate the patient satisfaction at tertiary cancer hospitals in China, and explore its determinants.Methods:Based on the fifth third-party evaluation of China Healthcare Improvement Initiative, an inpatient satisfaction survey was conducted from January 2021 to March 2021 in 33 tertiary cancer hospitals in China. Inpatient satisfaction was analyzed, and Chi-square test and binary multivariate logistic regression were run, using the level of overall inpatient satisfaction as a dependent variable.Results:A total of 5 417 inpatients in tertiary cancer hospitals was recruited with 49.8% men. The inpatient at the age of 35-59 accounted for 56.0%, and they were 52.8±13.9 years old. The level of overall inpatient satisfaction was 98.90%. The inpatient satisfaction rates of meal service, waiting time for admission and psychological counseling service provided by hospital were relatively poor, which were 78.75%, 92.40% and 94.11%, respectively. The regression showed that level of overall inpatient satisfaction in the central and western regions(compared with eastern area), with urban and rural residents basic medical insurance or other type(compared with urban employee basic medical insurance), of breast cancer patients(compared with other disease), with unsured postoperative metastasis(compared with non-postoperative metastasis), with low self-rated health score(compared with the score of between 81 and 100)was lower.Conclusions:The inpatients in tertiary cancer hospitals in China is highly satisfied with the care provided. In the future, more attention should be paid to the dimension of lower patient satisfaction, such as diet and psychological counseling.
