Objective To explore the effectiveness of different intervention strategies in response to outbreaks of emerging highly pathogenic respiratory infectious diseases(RIDs)in mega-city in China,and provide decision-ma-king basis for effective response to emerging RIDs.Methods A susceptible-exposed-infectious-recovered(SEIR)transmission dynamics model was constructed,referencing to and combining the pathogenicity and infectivity para-meters of previous emerging RIDs.The outbreak of emerging highly pathogenic RIDs with low,moderate,and high infectivity in a mega-city with a population of 10 million in China was simulated,the development of the epidemic within 100 days after implementing different combinations of non-pharmaceutical interventions(NPIs)in response to the outbreak was compared.Results When highly pathogenic RIDs outbreak occurred,and if its infectivity was low(R0 was about 1.5),it was unnecessary to adopt strict NPIs to control epidemic.If its infectivity was moderate(R0 was about 6),different intensities of NPIs were needed based on its existing infection scale.When the initial num-ber of infected cases was 50,moderate-intensity NPIs could keep the infection and death at a low level within 100 days,and the required bed number in hospital for cases could be kept below the national average reserve level.But when the scale of infection exceeded 100 cases,high-intensity NPIs were needed to control the development of the epidemic.In the case of extremely strong infectivity(R0 was about 10),regardless of the scale of infection,only immediate high-intensity NPIs could control the epidemic,infection and death scale.Conclusion In case of out-breaks of highly pathogenic RIDs,adopting appropriate NPIs as early as possible based on their epidemiological characteristics and infection scale is necessary to minimize the harm to the population.

Objective: To investigate the association of mixed exposure to greenness and nitrogen dioxide(NO₂) and hypertension among the older adults aged 65 years and over in China. Methods: The study subjects were from the Chinese Longitudinal Healthy Longevity Survey from 2017 to 2018. A total of 15 423 older adults aged 65 years and over meeting the criteria were finally included in the study. A questionnaire survey was used to collect information on demographic characteristics, lifestyle habits and self-reported prevalence of hypertension. Blood pressure values were obtained through physical examination. The level of normalized difference vegetation index(NDVI) was measured by the Medium-resolution Imaging Spectral Radiator(MODIS) of the National Aeronautics and Space Administration(NASA). The concentration of NO₂ was from China's surface air pollutant data set. Meteorological data was from NASA MERRA-2. The exposure to NDVI and NO₂ for each study subject was calculated based on the area within a 1 km radius around their residence. The association between mixed exposure of NDVI and NO₂ as well as their interaction and hypertension in older adults was analyzed by using the multivariate logistic regression model. The restrictive cubic spline(RCS) function was used to explore the exposure-response relationship between greenness and NO₂ and the risk of hypertension in study subjects. Results: The mean age of 15 423 older adults were (85.6±11.6). Women accounted for 56.3%(8 685/15 423) and 55.6%(8 578/15 423) lived in urban areas. The mean time of residence was (60.9±28.5) years. 59.8% of participants were with hypertension. The mean NDVI level was 0.41±0.13, and the mean NO₂ concentration was (32.18±10.36) μg/cm³. The results of multivariate logistic regression analysis showed that NDVI was inversely and linearly associated with the hypertension in older adults, with the OR(95%CI) value of 0.959(0.928-0.992). Compared with the T₁ group of NDVI, the risk of hypertension was lower in the T₃ group, with the OR(95%CI) value of 0.852(0.769-0.944), and the trend test was statistically significant(P<0.05). Compared with the T₁ group of NO₂, the risk of hypertension was higher in the T₂ and T₃ groups, with OR(95%CI) values of 1.160(1.055-1.275) and 1.244(1.111-1.393), and the trend test was statistically significant (P<0.05). The result of the RCS showed that NDVI was inversely and linearly associated with hypertension in older adults. NO₂ was nonlinearly associated with hypertension in older adults. The interaction analysis showed that NDVI and NO₂ had a negative multiplicative interaction on the risk of hypertension, with OR(95%CI) value of 0.995(0.992-0.997). Conclusion: Exposure to greenness and NO₂ are associated with hypertension in older adults.

Objective:To compare the postoperative adjacent segment degeneration (ASD) between the microscopically anterior cervical discectomy with fusion (ACDF) and anterior cervical corpectomy with fusion (ACCF) in the treatment of cervical spondylotic myelopathy and its influencing factors.Methods:Fifty patients with cervical spondylotic myelopathy treatment in the Qinzhou Second People′s Hospital from July 2018 to July 2020 were selected, they were divided into two groups, 25 patients performed ACDF (ACDF group), and 25 patients performed ACCF (ACCF group). The perioperative period, efficacy and incidence of ASD were compared between the two groups, and the influencing factors of ASD were analyzed.Results:The intraoperative blood loss, operation time, length of hospital stay and postoperative drainage in ACCF group were higher than those in ACDF group: (58.34 ± 8.61) ml vs. (46.77 ± 7.24) ml, (99.57 ± 10.72) min vs. (86.14 ± 9.64) min, (8.97 ± 1.43) d vs. (7.56 ± 1.24) d, (17.92 ± 2.95) ml vs. (14.28 ± 2.66) ml, there were statistical differences ( P<0.05). The postoperative Japanese Orthopaedic Association (JOA) scores and Neck Disability Index (NDI) scores in the two groups were improved significantly ( P<0.05), but the scores of JOA and NDI in the two groups had no significant differences ( P>0.05). The incidence of ASD in the two groups had no significant differences ( P>0.05). The Cox univariate analysis showed that age >59 years, intervertebral disc degeneration, number of fusion segments >2, osteoporosis and postoperative ASD were risk factors for ASD( P<0.05). Conclusions:The effect of microscopically ACDF is similar to that of ACCF in the treatment of cervical spondylotic myelopathy, but ACDF has the advantages of less trauma and quick recovery. The risk of postoperative ASD should be vigilant for patients with age >59 years old, intervertebral disc degeneration, number of fusion segments >2 or osteoporosis.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Objective:To investigate the long-term clinical effect of deep brain stimulation (DBS) on patients with Parkinson's disease (PD) at Hoehn-Yahr stage 2.5-5 and the differences of clinical effect among patients at different Hoehn-Yahr stages.Methods:A total of 69 PD patients (7 at Hoehn-Yahr stage 2.5, 27 at stage 3, 31 at stage 4, and 4 at stage 5) accepted DBS in Department of Functional Neurosurgery, Affiliated Brain Hospital of Nanjing Medical University from May 2014 to December 2016 were selected for long-term follow-up observation at 60 months after DBS. Unified Parkinson's Disease Rating Scale (UPDRS) was evaluated in the "off" phase of the patients before DBS and the "off" phases of the drugs under DBS start-up and continuous treatment at 6, 12, 24, 36, 48 and 60 months after DBS, respectively; Parkinson's Quality of Life Questionnaire (PDQ-39) and levodopa equivalent dose (LED) data were collected before and 6, 12, 24, 36, 48 and 60 months after DBS. DBS parameters of the patients were collected at 12 months after DBS; the total stimulation power, single pulse average energy and large single pulse energy were calculated. The differences in UPDRS-III scores, PDQ-39 scores and LEDD in these patients before DBS and at different time points after DBS were compared; the differences in UPDRS-III and PDQ-39 scores at different time points after DBS and postoperative DBS parameters at 12 months after DBS in patients at different Hoehn-Yahr stages were compared.Results:Compared with those before DBS, the UPDRS-III scores, PDQ-39 scores and LED were significantly reduced at 6, 12, 24, 36, 48 and 60 months after DBS ( P<0.05). Significant differences in UPDRS-III scores were noted between patients at Hoehn-Yahr stage 5 and Hoehn-Yahr stage 2.5 and stage 3 at 12 and 24 months after DBS ( P<0.05); however, no significant differences in UPDRS-III scores were noted between patients at Hoehn-Yahr stage 5 and Hoehn-Yahr stage 4 at same time points ( P>0.05); and no significant differences in UPDRS-III scores were noted between patients at Hoehn-Yahr stage 5 and patients at Hoehn-Yahr stage 2.5, stage 3, and stage 4 at other time points ( P>0.05). No significant differences in PDQ-39 scores were noted between patients at different Hoehn-Yahr stages at 6, 12, 24, 36, 48, and 60 months after DBS ( P>0.05). No significant difference in total stimulation power, single pulse average energy or large single pulse energy was noted among patients at different Hoehn-Yahr stages at 12 months after DBS ( P>0.05). Conclusion:DBS is long-term effective in improving motor function and quality of life in PD patients at Hoehn-Yahr stage 2.5-5, and patients at Hoehn-Yahr stage 5 do not need higher DBS parameters to obtain similar clinical improved effects as patients at Hoehn-Yahr stage 2.5-4.

Objective:To investigate the role of TcpC in uropathogenic Escherichia coli (UPEC)-induced cystitis in mice and to preliminarily analyze the pathogenic mechanism. Methods:C57BL/6 mice were injected with 10 9 CFU wild-type UPEC CFT073 (CFT073 wt) or tcpc gene-deleted mutant (CFT073 Δ tcpc) from urethra into bladder to construct the mouse model of cystitis. The mice were sacrificed 3 d after infection and the bladders were taken to observe the gross pathological changes. Histopathological changes in bladder tissues were observed after HE staining. Immunohistochemistry was used to detect TcpC in bladder tissues. Bacterial loads in urine samples of UPEC-infected mice were counted by tenfold dilution method, and the presence of tcpc gene in the genomic DNA of bacteria from the bladder and urine samples of CFT073 wt-infected mice was measured by PCR. Real-time quantitative RT-PCR (qRT-PCR) and Western blot were performed to detect the expression of TcpC at mRNA and protein levels in macrophages after CFT073 wt infection. The influence of UPEC strains on the activation of NF-κB signaling pathway in macrophages were determined by Western blot. The levels of proinflammatory factors and the bacterial and cell activity after infecting macrophages with UPEC strains were detected by ELISA, laser confocal microscope and fluorescence microscope, respectively. Results:Compared with the mice with CFT073 Δ tcpc infection, CFT073 wt-infected mice had significantly enlarged bladder and severe neutrophil infiltration and abundant TcpC in bladder tissues. The number of bacteria in the urine of CFT073 wt-infected mice was significantly greater than that of the CFT073 Δ tcpc group. PCR results showed that the bacteria in bladder or urine were CFT073 wt. The expression of TcpC at both mRNA and protein levels in macrophages increased significantly after CFT073 wt infection. Moreover, in CFT073 wt-infected macrophages, the expression of IκBα was promoted and the phosphorylation of p65 and the production of proinflammatory factors were suppressed. TcpC was instrumental in the survival and invasion of CFT073 wt in macrophages. Conclusions:TcpC expression increased significantly in mice with CFT073 wt-induced cystitis. TcpC inhibited the activation of NF-κB signaling pathway and the production of proinflammatory factors in macrophages to improve the survival rate of CFT073 wt, which was closely related to the pathogenesis and immune evasion of UPEC.

Sarglanoids A-F, six new sesquiterpenoids belonging to eudesmane (1-5) and eremophilane (6) types, were isolated from the leaves of Sarcandra glabra, a famous traditional Chinese medicine (TCM). Their structures including absolute configurations were elucidated through extensive spectroscopic analysis and electronic circular dichroism (ECD) calculations. Compounds 1-2 were rare N-containing eudesmane-type sesquiterpenoids. Compound 3 exhibited inhibitory activity against nitric oxide (NO) production in lipopolysaccharides (LPS)-induced RAW 264.7 cells with IC₅₀ values at 20.00 ± 1.30 μmol·L^-1. These findings provide scientific evidence for sesquiterpenoids as the material foundation of S. glabra.
