Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology， Western medicine obstetrics and gynecology， and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion， the experts concluded that chromosome， endocrine， and immune abnormalities were the key factors for the occurrence of threatened abortion， and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion， TCM has advantages in preventing miscarriages， alleviating clinical symptoms and TCM syndromes， relieving anxiety， regulating reproductive endocrine and immune abnormalities， personalized and diversified treatment， enhancing efficiency and reducing toxicity， and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

Objective:To investigate the causal relationship between intestinal flora and benign biliary diseases by genome-wide Mendelian randomization.Methods:This is a retrospective observational study. The data from the genome-wide association study of the gut microbiota from 18 340 samples from the MiBioGen consortium were selected as the exposure group,and the data from the genome-wide association study of biliary tract diseases were obtained from the FinnGen consortium R8 as the outcome group. There were 1 491 cases of primary sclerosing cholangitis,32 894 cases of cholelithiasis,3 770 cases of acalculous cholecystitis,and 34 461 cases of cholecystitis. Single nucleotide polymorphisms were screened as instrumental variables,and the Mendelian randomization method was used to infer the causal relationship between exposures and outcomes. The inverse variance weighting method (IVW) was used as the main basis, supplemented by heterogeneity,pleiotropy and sensitivity tests.Results:Coprococcus 2 was associated with a reduced risk of cholelithiasis (IVW OR=0.88,95% CI:0.80 to 0.97, P=0.012) and cholecystitis (IVW OR=0.88,95% CI:0.80 to 0.97, P=0.011). Coprococcus 3 was associated with cholelithiasis (IVW OR=1.15,95% CI:1.02 to 1.30, P=0.019) and acalculous cholecystitis(IVW OR=1.48, 95% CI: 1.08 to 2.04, P=0.016) and cholecystitis (IVW OR=1.17, 95% CI: 1.02 to 1.33, P=0.020). Peptococcus was associated with an increased risk of cholelithiasis (IVW OR=1.08, 95% CI:1.02 to 1.13, P=0.005) and cholecystitis (IVW CI=1.07, 95% CI:1.02 to 1.13, P=0.010). Clostridiumsensustricto 1 was associated with an increased risk of cholelithiasis (IVW OR=1.16,95% CI:1.02 to 1.31, P=0.020) and cholecystitis (IVW OR=1.16, 95% CI:1.03 to 1.30, P=0.015). Eubacterium hallii was associated with an increased risk of primary sclerosing cholangitis (IVW OR=1.43, 95% CI: 1.03 to 1.99, P=0.033). Eubacterium ruminantium (IVW OR=0.87, 95% CI: 0.76 to 1.00, P=0.043) and Methanobrevibacter (IVW OR=0.81, 95% CI: 0.68 to 0.98, P=0.027) were associated with a reduced risk of acalculous cholecystitis. Conclusions:Eight intestinal bacterial genera maybe play pathogenic roles in benign biliary diseases. Eubacterium hallii can increase the risk of primary sclerosing cholangitis. Peptococcus and Clostridiumsensustricto 1 can increase the risk of cholelithiasis and generalized cholecystitis. Coprococcus 3 have multiple correlations with biliary stones and inflammation.
