Objective:This study aimed to assess the infection status of cytomegalovirus (CMV) and Epstein-Barr virus (EBV) in healthy populations in China over the past decade and analyze the differences in CMV and EBV infection and related risk factors in healthy populations before and after the lifting of coronavirus disease 2019 (COVID-19) pandemic control measures.Methods:This study retrospectively analyzes the CMV and EBV infection status of 8 827 healthy donors who underwent prehematopoietic stem cell transplantation screening at Peking University People's Hospital from January 2014 to December 2023. Logistic regression analysis was conducted to determine the risk factors for CMV and EBV infection.Results:The CMV and EBV IgG positivity rates were 94.52% and 95.40% among the healthy donors, respectively, with no significant differences before and after the lifting of pandemic control measures (all P value>0.05). However, IgG antibody titers increased [CMV: (100.44±36.50) U/ml vs (109.98±36.31) U/ml, P<0.001; EBV: (281.57±226.79) U/ml vs (361.08±268.58) U/ml, P<0.001] after lifting the COVID-19 restrictions. However, the CMV IgM positivity rate remained unchanged. The EBV IgM positivity rate significantly increased after lifting measures (2.77% vs 6.29%, P<0.001), reaching 8.10% within 3 months. Further analysis of the factors affecting EBV IgM positivity revealed that gender ( OR=1.479, 95% CI 1.169-1.872, P=0.001), age[compared with the group younger than 18 years, the 18-50-year age group ( OR=0.584, 95% CI 0.421-0.820, P=0.002), the >50-year age group ( OR=0.389, 95% CI 0.248-0.610, P<0.001) ], and the lifting of COVID-19 restrictions ( OR=2.360, 95% CI 1.287-3.047, P<0.001) were independent factors influencing EBV IgM positivity in the general population. The EBV IgM positivity rate in individuals under 18 years old was not affected by gender or the lifting of COVID-19 restrictions when stratified by age group. Both genders ( OR=1.499, 95% CI 1.138 - 1.975, P=0.004) and the lifting of COVID-19 restrictions ( OR=2.608, 95% CI 1.940-3.507, P<0.001) were independent factors affecting EBV IgM positivity in the 18-50-year age group. The lifting of COVID-19 restrictions ( OR=2.222, 95% CI 1.101-4.484, P=0.026) was the sole independent factor affecting EBV IgM positivity in individuals over 50 years old. Conclusions:Previous infection rates of CMV and EBV are high in healthy populations in China, which increase with age. COVID-19 infection may increase EBV reactivation rates in healthy individuals, with a more pronounced effect on those aged >18 years.

Objective:To analyze the risk factors of multidrug-resistant organism（MDRO）infection among patients in neurosurgery intensive care unit（NSICU）and to construct a risk prediction nomogram.Methods:A total of 434 patients admitted in the NSICU of the First Affiliated Hospital of Kangda College of Nanjing Medical University from August 2021 to October 2022 were enrolled in the study. Patients were divided into modeling group（ n=217）and validation group（ n=217）. Multivariate Logistic regression was used to analyze the risk factors of MDRO infection in patients，and R software was used to construct a risk prediction nomogram.The prediction power of the nomogram was evaluated with receiver operating characteristic（ROC）curve，the calibration of the model was assessed with Hosmer-Lemeshow（H-L）goodness-of-fit method. Results:Multivariate Logistic regression analysis showed that the underlying disease≥3（ OR=2.580，95% CI 1.322-5.035），the combination of antimicrobial drugs >10 days（ OR=2.336，95% CI 1.182-4.615），hypoproteinemia（ OR=1.962，95% CI 1.031-3.735），invasive operation time（10-20 d： OR=2.358，95% CI 1.048-5.306；>20 d： OR=3.486，95% CI 1.643-7.395）and GCS≤8 points（ OR=2.961，95% CI 1.470-5.963）were independent risk factors of MDRO infection among patients in NSICU. The area under the curve（AUC）of the nomogram in predicting the risk of MDRO infection for patients in modeling group was 0.787（95% CI 0.725-0.849）with a sensitivity of 73.3% and a specificity of 72.5%，the H-L test results were χ2=7.482， P=0.486，the calibration curve was close to the ideal curve，and the mean absolute error was 0.022. The AUC of the nomogram in predicting MDRO infection for patients in verification group was 0.800（95% CI 0.739-0.861）with a sensitivity of 74.7% and a specificity of 73.9%，the H-L test results were χ2=9.824， P=0.278，the calibration curve was close to the ideal curve，and the average absolute error was 0.015. Conclusion:The nomogram constructed based on the risk factors can effectively predict the risk of MDRO infection for patients in neurosurgical ICU，which may be used in clinic pratcice.

AIM: To observe the effect ofacacia honey (AH) on serum uric acid level and renal function in potassium oxonate modelrats after drinking AH aqueous solution. METHODS: Sixty male SD rats were selected and randomly divided into control group (CON group), potassium oxonate model group (OA model group), 10% fructose group (10% F group) and different concentration honey groups (25%, 12.5% and 6.25% AH groups). All rats were fed with normal diet.The rats in CON group were subcutaneously injected with 5% sodium carboxymethyl cellulose (CMC-Na) solution and drunk sterile water every day, while rats in other groups were injected with 100 mg / kg OA solution suspended with 5% CMC-Na subcutaneouslyand drunksterile water orfructose solution or AH solution of different concentrations every day. Before and during the 4-week test, rats were weighed and blood was taken once a week. At the end of test, urine and feces specimens or kidney tissues were collected and blood was taken from the abdominal aorta. The uric acid content in blood, urine, and feces and the levels of serum creatinine (Cre) and blood urea nitrogen (BUN) or inflammatory factors in kidney tissues were measured. Renal function and histology were evaluated. RESULTS: Compared with CON group, AH could significantly reduce the body weight of rats (P<0.05), increase the kidney organ coefficient, the levels of serum uric acid, and uric acid in urine or feces, and reduce the level of fecal uric acid (FUA) in rats. AH can down regulate the level of tumor necrosis factor alpha (TNF-a) (P< 0.05) and up regulate the expression of monocyte chemoattractant protein 1 (MCP-1) and transforming growth factor β - 1 (TGF - β1) in rats kidneys; AH can cause slight to mild dilatation of renal tubules and mild to moderate basophilic lesions of renal rubules in rat kidney in a dose dependent manner. CONCLUSION: In the doses rang of present study, AH can cause hyperuricemia, renal tubular dilatation and basophilic lesions, and lead to renal function damage in rats.

Objective:To understand the epidemiological characteristics of public health emergency events (PHEE) of varicella in China from 2006 to 2021 and related response performances.Methods:The data of varicella PHEE in 31 provinces of China from 2006 to 2021 were collected through the Public Health Emergency Management Information System, Microsoft Excel 2019 software and SPSS 26.0 statistical software were used to conduct descriptive epidemiological, statistical analysis on the time, area, location distribution, scale and epidemic management.Results:A total of 11 443 PHEE involving 341 048 related cases were reported from 2006 to 2021, with an annual attack rate of 1.78%-3.80% and a total attack rate of 2.33% (341 048/14 624 042). The number of PHEE and related cases of varicella decreased from 1 107 (35 349) in 2007 to 262 (6 884) in 2012 ( Z=-2.40, P<0.001), then increased year by year to 1 318 (42 649) in 2019 ( Z=2.58, P<0.001), with a significant decline since 2020. The varicella PHEE in China presents the seasonal characteristics,the peak is from April to June and from October to December, respectively. The sub-peak of varicella PHEE in eastern China generally appears 1-2 months earlier than in central and western China. Varicella PHEE reports are mainly distributed in eastern China, the attack rate is relatively high in western China, school-reported varicella PHEE was 88.26% of the total reports (10 099/11 443). The epidemic scale of varrcella PHEE typically range from 10 to 29 cases per year among the given outbreaks. The M ( Q1, Q3) of average number of cases, average duration, and average reporting interval of PHEE were 23 (16,35), 20 (14, 26) days, and 9 (5,19) days, respectively, and the reporting interval was positively correlated with the duration ( r=0.854, P<0.001). Conclusions:The varicella PHEE in China from 2006 to 2021 has not been effectively controlled. Schools are the key places to prevent and control varicella PHEE. Improving the sensitivity of varicella PHEE monitoring, strengthening the timely disposal of varicella epidemic, and promoting varicella vaccination are effective measures to prevent and control varicella PHEE.

A new definition of metabolic dysfunction-associated fatty liver disease (MAFLD) has recently been proposed. We aim to examine the associations of MAFLD, particularly its discordance from non-alcoholic fatty liver disease (NAFLD), with the progression of elevated brachial-ankle pulse wave velocity (baPWV) and albuminuria in a community-based study sample in Shanghai, China. After 4.3 years of follow-up, 778 participants developed elevated baPWV and 499 developed albuminuria. In comparison with the non-MAFLD group, the multivariable adjusted odds ratio (OR) of MAFLD group for new-onset elevated baPWV was 1.25 (95% confidence interval (CI) 1.01-1.55) and 1.35 (95% CI 1.07-1.70) for albuminuria. Participants without NAFLD but diagnosed according to MAFLD definition were associated with higher risk of incident albuminuria (OR 1.77; 95% CI 1.07-2.94). Patients with MAFLD with high value of hepamet fibrosis score or poor-controlled diabetes had higher risk of elevated baPWV or albuminuria. In conclusion, MAFLD was associated with new-onset elevated baPWV and albuminuria independently of body mass index, waist circumference, and hip circumference. Individuals without NAFLD but diagnosed as MAFLD had high risk of albuminuria, supporting that MAFLD criteria would be practical for the evaluation of long-term risk of subclinical atherosclerosis among fatty liver patients.

ObjectiveTo analyze the quality changes of Platycladi Semen before and after the deterioration of moth-eaten and rancidity during storage. MethodFour types samples of Platycladi Semen， including normal， moth-eaten， oxidative rancidity and hydrolytic rancidity， were determined for volatile components， odor， and taste based on headspace solid phase microextraction/gas chromatography-mass spectrometry （HS-SPME/GC-MS） and electronic sensory techniques such as electronic nose and electronic tongue. Volatile components were identified by searching the database and manual comparison， the odor and taste were determined by the response values of the electronic nose and electronic tongue sensors， and the difference between samples before and after deterioration was studied by multivariate statistical analysis. ResultA total of 85 compounds were identified in Platycladi Semen samples. Compared with the normal samples， the number of volatile compounds in samples after hydrolytic rancidity decreased by 5， the number of volatile compounds in samples after moth-eaten and oxidative rancidity increased by 1 and 21， respectively. Aldehydes and acids accounted for majority of types. Among them， the contents of N-hexanoic acid， hexanal and propionic acid in the samples of oxidative rancidity reached 11.49%， 10.21% and 7.52%， which became the key indicators of rancidity. There was significant variance among the odor components corresponding to W1W， W2W and W1S sensors by electronic nose analysis. It was indicated that the value of sourness in deteriorated samples generally increased by mean of electronic tongue analysis. Compared with normal samples， the moth-eaten samples had changed slightly and rancidity samples had changed significantly especially oxidative rancidity samples of volatile components， odor and taste by multivariate statistical analysis. ConclusionIn terms of Platycladi Semen， the oxidative rancidity caused by nature storage for 12 months has the greatest impact on the quality. Therefore， it should be mainly to prevent oxidative rancidity to ensure the quality of Platycladi Semen.
