Objective:To investigate the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Weinan City, Shaanxi Province, and study the predictive effect of the seasonal autoregressive integrated moving average (SARIMA) model.Methods:Relevant information on HFRS cases reported by the China Disease Prevention and Control Information System from January 2010 to August 2024 in Weinan City, as well as the epidemiological investigation data on clinical diagnosis and confirmed HFRS cases in Weinan City were collected. Epidemiological characteristics of HFRS were analyzed by descriptive epidemiological methods. At the same time, a SARIMA model was constructed based on the monthly incidence of HFRS from 2010 to 2023, the incidence of HFRS from January to August 2024 was used to test the simulation prediction effect, and the optimal model was used to predict the incidence of HFRS from September to December 2024.Results:A total of 4 373 HFRS cases were reported in Weinan City from 2010 to 2023, with an average annual incidence of 6.39/100 000. The incidence rate showed a cyclical fluctuation trend, reaching two peaks in 2012 (10.25/100 000) and 2021 (12.26/100 000), respectively. The incidence of HFRS presented a seasonal bimodal distribution, with the peak predominantly in autumn and winter (from October to January of the following year), accounting for 67.83% (2 966/4 373), and the peak in spring and summer (form May to July) accounting for 17.27% (755/4 373). HFRS cases were reported in all counties (cities and districts) of Weinan City, and the top 3 annual incidence rates were Huazhou District (17.84/100 000), Linwei District (16.10/100 000) and Huayin City (9.15/100 000). The age of onset was mainly concentrated in the age group of 15 - 59 years old, accounting for 68.31% (2 987/4 373). The male to female ratio was 2.96∶1.00 (3 268∶1 105). The main occupation was farmers, accounting for 82.07% (3 589/4 373). SARIMA (1, 0, 1) (2, 1, 1) 12 model was the optimal model for short-term prediction of HFRS incidence rate in Weinan City, and the residual difference was listed as white noise ( Q = 7.45, P = 0.878), the model could be used for disease prediction. The model was used to predict the incidence of HFRS from September to December 2024, and the predicted values of each month were 0.17/100 000, 0.59/100 000, 1.85/100 000 and 1.61/100 000, respectively. Conclusions:The epidemic range of HFRS in Weinan City is wide, and the incidence has obvious seasonality. The population are mainly males, young and middle-aged adults and farmers. The SARIMA (1, 0, 1) (2, 1, 1) 12 model constructed can be used for predicting the short-term incidence trend of HFRS in Weinan City.

Objective Taking the medicinal excipient pectin as an example,based on the ICH Q3C risk assessment and management concept,this paper explores the control standards for residual solvents in pectin in the variety text of the Chinese Pharmacopoeia.Methods Pectin products from different processes and manufacturers were analyzed,the types of solvent residues in pectin were identified,and the solvent residues of products from different manufacturers were analyzed by gas chromatography.Results According to the product process,there was a risk of residual methanol(class 2),ethanol and isopropanol(class 3)in pectin products.In 18 batches of samples,the residual amount of methanol was measured in the range of 0.05%-0.17%,the residual amount of ethanol was in the range of 0.01%-0.38%,isopropanol was not detected,and the total amount of residual solvents was in the range of 0.07%-0.55%.Conclusions It is suggested that the residual solvent inspection item may not be listed separately in the main text of the pectin standard of the Chinese Pharmacopoeia.It is recommended that the manufacturer is required to indicate the name and limit of residual solvents under the labeling item of the standard.

The clinical data of a child with neurodevelopmental disorders caused by a new mutation in the POLR2A gene were retrospectively analyzed.The patient was a 4-year and 2-month-old girl who presented at Xiamen Hospital, Children′s Hospital of Fudan University in June 2024 with clinical manifestations of early infantile hypotonia, muscle atrophy of both lower limbs, global developmental delay (including delays in motor and language development, mental retardation, etc.), sleep difficulties, feeding difficulties, autistic behaviors (namely, social withdrawal), epilepsy, and auditory deficits.The child had one seizure at the age of 2 years and 8 months and one at the age of 4 years, but seizures are currently controlled by drugs.Cranial magnetic resonance imaging and CT showed agenesis of the corpus callosum, bilateral ventricular widening and cerebellar hypoplasia.Whole exome sequencing showed a new mutation c. 3364C>T (p.P1122S) in the POLR2A gene (NM_000937) in the child, and no related gene variants were found in either parental lineage.According to the American College of Medical Genetics and Genomics rating guidelines, it was determined to be a suspected pathogenic variant (PS2+ PM2+ PP3+ PP4).The mutation site has not been reported at home and abroad.The c. 3364C > T ( p. P1122S ) mutation of the POLR2A gene can cause neurodevelopmental disorders, severe phenotypes and poor long-term prognosis.

Objective To explore the effect of the physician-nurse-social worker linkage rehabilitation model on the psychological status in patients receiving methadone maintenance treatment(MMT).Methods Ninety-four patients who received MMT were enrolled and randomly divided into experimental group(n = 48)and control group(n = 46).The experimental group received physician-nurse-social worker linkage rehabilitation model intervention,while the control group received conventional methadone treatment service.The anxiety,depression and quality of life of the two groups were evaluated before the intervention,3 months and 6 months after the intervention.Results After 6 months of physician-nurse-social worker linkage rehabilitation mode intervention,the depression status and the anxiety status of the experimental group subjects were significantly improved compared with those before intervention,and both BDI and BAI scores were significantly lower than those of the control group subjects(P<0.05).Moreover,the proportion of"had depression"and"had anxiety"in the experimental group were significantly lower than those in the control group(P<0.05).After 6 months of intervention,the QOL-DA score of the experimental group subjects(183.77±8.90)was significantly higher than that of the control group sub-jects(174.76±11.14)(P<0.01).Conclusion The physician-nurse-social worker linkage rehabilitation model had certain advantages in improving the psychological state of MMT patients,which is worthy of promotion.

Objective:To investigate the clinical phenotype and gene mutation in a child with developmental disorders caused by CTNNB1 gene mutation. Methods:Clinical data of a child with CTNNB1 gene mutation who was admitted to Xiamen Hospital of Fudan University Affiliated Pediatric Hospital in May 2017 were collected, whole exome sequencing technology was applied to verify the family lineage of the child, and the pathogenicity of mutation site was analyzed. Results:The patient was a 6 years and 1 month old male, with a clinical phenotype including mental retardation, motor developmental disorders, speech disorders, visual disorders (internal strabismus), microcephaly, and behavioral problems (social withdrawal, overdependence, etc.), as well as panic syndrome (i.e., sudden shrieking in response to auditory and visual stimuli, extensional rigidity of the body, etc., followed by short periods of general extensional rigidity). The whole exome sequencing results showed the presence of a de novo mutation c.283(exon4)C>T in the CTNNB1 gene, and the c.283(exon4)C>T mutation was interpreted as pathogenic (PVS1+PS2+PS1+PM2+PM) according to the American College of Medical Genetics and Genomics variant classification criteria and guidelines. No relevant genetic variants were found in the parental family verification. Conclusion:CTNNB1 gene mutation c.283(exon4)C>T can cause neurodevelopmental disorders, including mental retardation, motor developmental disorders, speech disorders, visual disorders, microcephaly and behavioral abnormalities.
