Cervical spine health issues not only seriously affect patients' quality of life but also impose a heavy burden on the social healthcare system. Existing guidelines lack sufficient clinical guidance on lifestyle and work habits, such as exercise, posture, daily routine, and diet, making it difficult to meet practical needs. To address this, relying on the China Association of Chinese Medicine, Wangjing Hospital of China Academy of Chinese Medical Sciences took the lead and joined hands with more than ten institutions to form a multidisciplinary guideline development group. For the first time, the group developed the Guidelines for Cervical Spine Health Intervention based on evidence-based medicine methods, strictly following the standardized procedures outlined in the World Health Organization Handbook for Guideline Development and the Guiding Principles for the Formulation/Revision of Clinical Practice Guidelines in China (2022 Edition). This proposal systematically explains the methods and steps for developing the guideline, aiming to make the guideline development process scientific, standardized, and transparent.

OBJECTIVE: To analyze the efficacy and safety of decitabine-based myeloablative preconditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with acute myeloid leukemia (AML). METHODS: The clinical characteristics and efficacy of 115 AML patients who underwent allo-HSCT at the First Medical Center of Chinese PLA General Hospital from August 2018 to August 2022 were retrospectively analyzed, including 37 patients treated with decitabine conditioning regimen (decitabine group) and 78 patients without decitabine conditioning regimen (non-decitabine group). The cumulative incidence of relapse (CIR), overall survival (OS), leukemia-free survival (LFS), non-relapse mortality (NRM) and graft versus host disease (GVHD) were analyzed. RESULTS: For the patients in first complete remission (CR1) state before allo-HSCT, the 1-year relapse rates of decitabine group(22 cases) and non-decitabine group(69 cases) were 9.1% and 29.6%, respectively, the difference was statistically significant(P =0.042). The 1-year cumulative incidence of acute graft-versus-host disease (aGVHD) in decitabine group and non-decitabine group was 62.2% and 70.5%, respectively, and the 1-year cumulative incidence of chronic inhibitor-versus-host disease (cGVHD) was 18.9% and 14.1%, respectively, there were no significant differences in the incidence of aGVHD and cGVHD between the two groups (P >0.05). Of the 115 patients, there were no significantly differences in the 1-year CIR(21.7% vs 28.8%, P =0.866), NRM(10.9% vs 3.9%, P =0.203), OS(75.2% vs 83.8%, P =0.131) and LFS(74.6% vs 69.1%, P =0.912) between the decitabine group(37 cases) and the non-decitabine group(78 cases). CONCLUSION Decitabine-based conditioning regimen could reduce the relapse rate of AML CR1 patients with good safety.

Salmonella enterica serovar Goldcoast isolates from Yangzhou were analyzed for assessment of their pathogenic and ge-nomic characteristics.From 2017 to 2023,eight strains were detected through foodborne disease surveillance and health check-ups.These strains exhibited resistance to two to seven antibiotic classes,and all strains bore a T57S mutation in the parC gene.Notably,50％(4/8)of the strains carried sulfonamide resistance genes(sul1 or sul3),and 37.5％(3/8)were positive for extended-spectrum beta-lactamase(ESBL)genes,including blaCTX-M-55 and blaTEM-1.Multilocus sequence typing(MLST)revealed that ST358(five strains)and ST2529(three strains)were the predominant sequence types,corresponding to CRISPR Ⅰ and Ⅱ groups,respectively.Single nucleotide polymorphism(SNP)phylogenetic analysis indicated a close genetic relationship between the case isolate Sal-2214 and strains from multiple regions,with a SNP difference≤20,thus suggesting potential inter-regional transmission.For example,one isolate from the stool of a 4-year-old child with diarrhea(Sal-2214)carried the beta-lactam resistance gene(blaCTX-M-55)and exhib-ited high resistance to cefotaxime(CTX)and ceftazidime(CAZ).These findings indicated that S.enterica Goldcoast emerged in Yang-zhou from 2022,and was characterized by multidrug resistance and a genetic relationship with strains from coastal regions.These find-ings highlight the need for enhanced resistance monitoring and trace-back studies to better understand the epidemiology and control the potential spread of this pathogen.

Objective:To investigate the current status of pruritus care in dermatology departments of public hospitals in China.Methods:A multicenter, cross-sectional survey was conducted. By convenience sampling, dermatology nurses were selected from 85 public hospitals across 17 provinces in China from September 2 to September 14, 2024, and a self-designed pruritus care questionnaire survey was conducted. The survey content included two parts: general information (e.g., education levels, professional titles, regions, hospital grades) and current status of pruritus care (e.g., pruritus care systems or standards, establishment of pruritus clinics, pruritus assessment, pruritus intervention measures, pruritus nursing training, and challenges in pruritus care) .Results:A total of 607 nurses were investigated, including 322 (53.0%) from general hospitals and 285 (47.0%) from specialized hospitals; 359 (59.1%) were from tertiary grade-A hospitals. In total, 264 (43.5%) nurses reported that pruritus clinics had been established in their hospitals, 218 (35.9%) reported that pruritus nursing teams had been set up, and 283 (46.6%) noted a lack of pruritus care systems or standards in their hospitals. The most commonly used anti-pruritus measures were physical therapy (51.2%) , drug treatment (37.9%) , and environmental management (10.9%) . There were 418 (68.9%) nurses who had received pruritus nursing training. The most frequently used pruritus assessment tools were the numeric rating scale ( n = 341, 56.2%) and the visual analog scale ( n = 268, 44.2%) , while 165 (27.2%) nurses had not used any assessment tools. The most challenging issues in pruritus care were the selection of pruritus assessment tools ( n = 303, 49.9%) and poor efficacy of pruritus control ( n = 113, 18.6%) . Tertiary grade-A hospitals and hospitals with pruritus clinics exhibited higher rates of establishing pruritus care systems/standards and providing pruritus nursing training compared with non-tertiary grade-A hospitals and hospitals without pruritus clinics respectively (all P < 0.05) . Conclusions:Public hospitals in China currently face issues such as inadequate pruritus care management systems, non-standardized pruritus assessment, and insufficient pruritus nursing training. Pruritus nursing levels were variable among different hospitals, and the standardization and homogeneity of pruritus nursing urgently need to be improved.

To establish a method for detecting Toxoplasma gondii based on recombinant polymerase amplification(RPA)technology and apply it to clinical sample validation of pet cats.Using the 529 repeat sequence of the Toxoplasma gondii gene as the target gene sequence,primers and probes were designed,and the Rep-529 recombinant plasmid was constructed as the standard.A fluorescent RPA reaction system was established.Dilute the plasmid standard 10 times to different concentrations as the detection template for sensitivity testing;Specific testing was conducted using genomic DNA from several parasitic spe-cies,including Toxoplasma gondii,Cryptosporidium,Neosporidium,Trichinella spiralis,Giardia flagellata,Babesia bo-vis and Theileria annulata as templates;Simultaneously,fluorescence RPA and RT-PCR were used to detect 52 positive and 40 negative cats clinical samples,and the coincidence rate of the detection results of the two methods were compared and ana-lyzed.The RPA reaction system was successfully established using PTRep recombinant plasmid as the standard,ToxD-F/ToxD-R as the primer,and RepD-P as the fluorescent probe.The reaction temperature was constant at 39 ℃,the reaction time was 30 minutes,and the detection sensitivity was 1 copy/μL.There is no significant cross reaction with parasites such as Cryptosporidium,Neosporidium,Trichinella spiralis,Giardia,Babesia bovis and Theileria annulata,and the specificity is good.A total of 92 clinical fecal samples from cats were tested,and the positive coincidence rate of fluorescence RPA detection method was higher than that of conventional RT-PCR method(98.08％vs.82.69％),and the difference of the positive rate was not statistically significant(X2=1.392,P＞0.05).The fluorescence RPA detection method for Toxoplasma gondii suc-cessfully established in this study has the characteristics of being fast,sensitive,specific,accurate,and reliable.It can be used as a rapid clinical detection kit for Toxoplasma gondii in cats and other animals,providing new technical support for the subsequent epidemiological monitoring and precise clinical diagnosis of toxoplasmosis in cats,other animals,and humans in the future.

Aim To observe the effect of lipopolysac-charide(LPS)induced supernatant of BV-2 cells on the inflammatory response and apoptosis of HT22 neu-rons.Methods After the concentration and time of LPS were determined by CCK-8 method,BV-2 cells were cultured with medium without LPS and medium containing LPS,the morphological changes of BV-2 microglia were observed by inverted microscope,and the CD86/CD206 ratio of BV-2 microglia was detected by immunofluorescence.Subsequently,BV-2 cell cul-ture supernatants were isolated and added to HT22 neuronal culture to observe the effect on the inflamma-tory response of HT22 neurons.The proliferation of HT22 neurons was detected by CCK-8 method and EdU method.The structural changes of HT22 neurons were observed under the microscope and examined by urani-um-lead staining.The levels of cytokines interleukin-1β(IL-1β),interleukin-10(IL-10),nuclear factor kappa-B(NF-κB)and tumor necrosis factor-α(TNF-α)were detected by enzyme-linked immunosorbent as-say(Elisa).Neuronal apoptosis was detected by the TUNEL method.The protein expressions of Bax,Bcl-2 and inflammatory factors were detected by Western blot.Results After induction with 1 mg·L-1 LPS,BV-2 cells exhibited increased cell body size,thicker protrusions on both side,and some cells showed de-formed protrusions,the CD86/CD206 ratio in BV-2 cells decreased,promoting the transformation of BV-2 cells from M2 type to M1 type.After treating with the culture supernatant of BV-2 cells,HT22 neuronal cell activity and proliferation were reduced,axons short-ened,and the number of cells decreased.Neuronal cell bodies were enlarged and some cells were de-formed,with damaged cell membranes,round cell nu-clei but displaced nucleoli from the normal position,swollen mitochondria with vacuoles,reduced internal ridge structures,and increased levels of inflammatory factors NF-κB,IL-1 β,and TNF-α(P＜0.05 or P＜0.01),while the anti-inflammatory factor IL-10 de-creased(P＜0.05),protein expression of the pro-apoptotic indicator Bax increased(P＜0.01),and the protein expression of the anti-apoptotic indicator Bcl-2 decreased(P＜0.05).Conclusion After induction of BV-2 cell polarization by LPS,the supernatant could inhibit HT22 neuronal cell viability,upregulate inflam-matory factor expression and promote apoptosis.

OBJECTIVE: Exposure to polycyclic aromatic hydrocarbons (PAHs) or metal(loid)s individually has been associated with neural tube defects (NTDs). However, the impacts of PAH and metal(loid) co-exposure and potential interaction effects on NTD risk remain unclear. We conducted a case-control study in China among population with a high prevalence of NTDs to investigate the combined effects of PAH and metal(loid) exposures on the risk of NTD. METHODS: Cases included 80 women who gave birth to offspring with NTDs, whereas controls were 50 women who delivered infants with no congenital malformations. We analyzed the levels of placental PAHs using gas chromatography and mass spectrometry, PAH-DNA adducts with ³²P-post-labeling method, and metal(loid)s with an inductively coupled plasma mass spectrometer. Unconditional logistic regression was employed to estimate the associations between individual exposures and NTDs. Least absolute shrinkage and selection operator (LASSO) penalized regression models were used to select a subset of exposures, while additive interaction models were used to identify interaction effects. RESULTS: In the single-exposure models, we found that eight PAHs, PAH-DNA adducts, and 28 metal(loid)s were associated with NTDs. Pyrene, selenium, molybdenum, cadmium, uranium, and rubidium were selected through LASSO regression and were statistically associated with NTDs in the multiple-exposure models. Women with high levels of pyrene and molybdenum or pyrene and selenium exhibited significantly increased risk of having offspring with NTDs, indicating that these combinations may have synergistic effects on the risk of NTDs. CONCLUSION Our findings suggest that individual PAHs and metal(loid)s, as well as their interactions, may be associated with the risk of NTDs, which warrants further investigation.

OBJECTIVE: To assess the independent and combined effects of air pollutants, meteorological factors, and greenspace exposure on new tuberculosis (TB) cases. METHODS: TB case data from Shanghai (2013-2018) were obtained from the Shanghai Center for Disease Control and Prevention. Environmental data on air pollutants, meteorological variables, and greenspace exposure were obtained from the National Tibetan Plateau Data Center. We employed a distributed-lag nonlinear model to assess the effects of these environmental factors on TB cases. RESULTS: Increased TB risk was linked to PM _2.5, PM ₁₀, and rainfall, whereas NO ₂, SO ₂, and air pressure were associated with a reduced risk. Specifically, the strongest cumulative effects occurred at various lags: PM _2.5 ( RR = 1.166, 95% CI: 1.026-1.325) at 0-19 weeks; PM ₁₀ ( RR = 1.167, 95% CI: 1.028-1.324) at 0-18 weeks; NO ₂ ( RR = 0.968, 95% CI: 0.938-0.999) at 0-1 weeks; SO ₂ ( RR = 0.945, 95% CI: 0.894-0.999) at 0-2 weeks; air pressure ( RR = 0.604, 95% CI: 0.447-0.816) at 0-8 weeks; and rainfall ( RR = 1.404, 95% CI: 1.076-1.833) at 0-22 weeks. Green space exposure did not significantly impact TB cases. Additionally, low temperatures amplified the effect of PM _2.5 on TB. CONCLUSION Exposure to PM _2.5, PM ₁₀, and rainfall increased the risk of TB, highlighting the need to address air pollutants for the prevention of TB in Shanghai.

Intra-aortic balloon pump(IABP),as the most commonly used percutaneous mechanical circulatory assist device,is routinely implanted through the femoral artery pathway.However,when implantation through the femoral artery pathway is difficult or contraindicated,other pathways including the brachial artery pathway,axillary artery pathway,etc.can be considered.IABP assisted interventional treatment for complex high-risk and indicated patients(CHIP)can reduce the risk of intraoperative complications,stabilize hemodynamics,increase the complete revascularization rate of CHIP,and improve long-term prognosis.The reverse guidewire technique can improve the success rate of percutaneous coronary intervention(PCI)for chronic total occlusion(CTO)of coronary arteries.In clinical practice,the reverse pathway is often chosen in addition to the forward pathway,such as the contralateral radial and brachial artery pathway,femoral artery pathway,etc.This article reports a case of bilateral femoral artery occlusion,in which IABP was implanted through the left brachial artery pathway,and then with the assistance of IABP,the right coronary artery CTO lesion was successfully opened through the right radial artery in the forward direction and the right brachial artery in the reverse direction,with the aim of providing reference for clinical PCI treatment for such special cases.
