This meta-analysis compared the clinical outcomes between two alternative surgeries for patients with cervical spondylosis, namely anterior cervical discectomy and fusion (ACDF) without plate (ACDFWP) vs. anterior cervical disc arthroplasty (ACDA). We searched databases, including PubMed, EMBASE, Cochrane Library, Google Scholar, and Web of Science (firstly available-2019). A standard meta-analysis was performed with the included studies. A Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) tool was used for the evaluation of the study quality of nonrandomized-controlled trials (nRCTs), while a Risk of Bias (RoB) battery was used for randomized controlled trials (RCTs). Eight studies involving 640 patients were included. No significant difference was found in the indices of Neck Disability Index (NDI) score, Visual Analog Score (VAS), Japanese Orthopaedic Association (JOA) score, operative time, blood loss, Swallowing Quality of Life Score (SWAL-QL), and complications. Cervical alignment was significantly better in the ACDFWP than in ACDA (mean difference (MD) = −0.67, 95% confidence interval (CI) [−1.11, −0.23], P = 0.003, I(2) = 20%). Although the alternative ACDFWP was slightly superior in terms of the index of cervical alignment, the limited research on this subject present insufficient evidence. Further well-designed studies are warranted in the future.

OBJECTIVE: To examine the efficacy of Qinghuayin (清化饮, QHY) in rat chronic atrophic gastritis (CAG) models and explored the molecular mechanism of QHY in treating CAG. METHODS: In total, 65 Wistar rats were randomly divided into the control (n = 10) and CAG groups (n = 55). CAG model rats were further divided into five groups: model (n = 10), vitacoenzyme (n = 10), low-dose QHY (n = 10), medium-dose QHY (n = 10), and high-dose QHY groups (n = 10). We analyzed histopathological changes using hematoxylin and eosin staining and measured interleukin (IL)-6 and IL-8 levels in serum using enzyme-linked immunosorbent assay (ELISA) (Boster Bio, Pleasanton, USA). In addition, gastrin (GAS), pepsinogen I (PGI), and PGII expressions were evaluated using ELISA. The protein and mRNA expression of toll-like receptor 4 (TLR4) and toll or interleukin-1 receptor domain-containing adaptor inducing interferon-β (TRIF) was detected by Western blotting and quantitative reverse transcription-polymerase chain reaction, respectively. RESULTS: Our results revealed that histopathological changes in CAG model rates could be restored by low-, medium-, and high-dose QHY. The changes in GAS and PGI/II expression demonstrated that QHY improved CAG. Serum IL-6 and IL-levels were decreased by QHY administration. TLR4 and TRIF were upregulated at the mRNA and protein levels in the model group but downregulated by QHY administration. CONCLUSION: We concluded that QHY could effectively improve the histopathological changes of the gastric mucosa induced by CAG in rats. The therapeutic mechanism of QHY may be related to inhibition of the inflammatory factors IL-6 and IL-8 and suppression of TLR4/TRIF mRNA and protein expression.

To observe lipid profiles and their alterations in hospitalized patients with COVID‐19 pneumonia (NCP) and evaluate the value of lipids for the prediction of the length of hospital stay (LOS), a total of 248 patients aged 18 years or older were enrolled in this retrospective study. At admission, the median levels of triglyceride (TG), total cholesterol (TC), high‐density lipoprotein cholesterol (HDL‐C), and low‐density lipoprotein cholesterol (LDL‐C) in all patients were 1.11, 4.00, 0.89, and 2.11 mmol/L, respectively. Compared with common cases (n = 174), severe cases (n = 74) exhibited higher TG and HDL‐C, and lower LDL‐C. Levels of TC and LDL‐C were negatively correlated with LOS. In 68 severe cases, serum lipids were followed up during hospitalization, and the median LOS was 29 days. The average levels of serum lipids were lowest at admission and gradually increased during hospitalization. Compared with the LOS ≤ 29 days group, serum levels of TC, HDL‐C, and LDL‐C were significantly lower in the LOS > 29 days group at admission; this lower trend was found in the subsequent tests for TC and LDL‐C but not for HDL‐C or TG. Multiple‐variant COX regression showed that levels of TC or LDL‐C at admission were independent risk of LOS prolongation. Together, these findings suggest that in patients with NCP, levels of TC and LDL‐C at admission were negatively correlated with LOS. In severe cases, the gradual increase in TC, LDL‐C, and HDL‐C during hospitalization might indicate gradual recovery. TC, Lipid levels at admission were low in coronavirus disease 2019 (COVID‐19) infected pneumonia (NCP‐19) patients. Lipid levels gradually increased during the recovery from NCP‐19. Lipid levels of TC, LDL and HDL are inversely connecting with the length of hospital stay in NCP‐19 patients. Monitoring of lipid alteration is important for therapeutic strategy in NCP‐19 patients.
