BACKGROUND:Multiple observational studies have suggested a potential association between telomere length and musculoskeletal diseases.However,the underlying mechanisms remain unclear. OBJECTIVE:To investigate the genetic causal relationship between telomere length and musculoskeletal diseases using two-sample Mendelian randomization analysis. METHODS:Genome-wide association study summary data of telomere length were obtained from the UK Biobank.Genome-wide association study summary data of 10 common musculoskeletal diseases(osteonecrosis,osteomyelitis,osteoporosis,rheumatoid arthritis,low back pain,spinal stenosis,gout,scapulohumeral periarthritis,ankylosing spondylitis and deep venous thrombosis of lower limbs)were obtained from the FinnGen consortium.Inverse variance weighting,Mendelian randomization-Egger and weighted median methods were used to evaluate the causal relationship between telomere length and 10 musculoskeletal diseases.Inverse variance weighting was the primary Mendelian randomization analysis method,and sensitivity analysis was performed to explore the robustness of the results. RESULTS AND CONCLUSION:(1)Inverse variance-weighted results indicated a negative causal relationship between genetically predicted telomere length and rheumatoid arthritis(odds ratio=0.78,95%confidence interval:0.64-0.95,P=0.015)and osteonecrosis(odds ratio=0.56,95%confidence interval:0.36-0.90,P=0.016).No causal relationship was found between telomere length and the other eight musculoskeletal diseases(all P>0.05).(2)Sensitivity analysis affirmed the robustness of these causal relationships,and Mendelian randomization-Egger intercept analysis found no evidence of potential horizontal pleiotropy(all P>0.05).(3)This Mendelian randomized study supports that telomere length has protective effects against rheumatoid arthritis and osteonecrosis.However,more basic and clinical research will be needed to support our findings in the future.

Objective:To explore the effects of information drug close-loop management mode on adverse events of nursing medication and to analyze the 46 cases of adverse events after implementing the information drug close-loop management mode so as to understand the event characteristics and formulate the countermeasures with the aim to reduce the nursing medication errors.Methods:We retrospectively analyzed the 46 cases of adverse events of nursing medication reported by system in the First Affiliated Hospital of Xiamen University after implementing the information drug close-loop management mode (from January to December 2018) . Among the 46 cases of events, we analyzed the classifications, causes and links of error and compared those events with adverse events of nursing medication before implementing the information drug close-loop management mode in 2017.Results:After carrying out the drug close-loop management, the adverse events of medication declined compared with that in 2017, but there was no statistical difference ( P>0.05) . The adverse events included 17 (17/46, 36.96%) errors in identification, 8 (8/46, 17.39%) medication omissions, 7 (7/46, 15.22%) errors in dose and 5 (5/46, 10.87%) errors in route. The links of medication errors were mainly in drug dispensing (26 cases) and arranging (14 cases) . Conclusions:Adverse events of medication most often occur in drug dispensing. The most common errors were misidentification. Nursing managers should formulate the preventive intervention based on the classifications and characteristics of adverse events in nursing medication administering, and monitor as well as improve the rate of sweeping code in drug close-loop, strength training for nurses, and check the drug dispensing and arranging well.

Objective: To investigate the association between nonalcoholic fatty liver disease (NAFLD) and serum magnesium level in patients with type 2 diabetic mellitus (T2DM). Methods: Clinical data of 1 273 consecutive patients with T2DM admitted in hospital from June 2013 to June 2017 were retrospectively analyzed. According to the quartile of serum magnesium levels, patients were divided into 4 groups: Q₁ group (≤ 0.79 mmol/L, n=376), Q₂ group (0.80-0.84 mmol/L, n=296), Q₃ group (0.85-0.89 mmol/L, n=287) , and Q₄ group (≥0.90 mmol/L, n=314). Logistic regression was used to analyze the association between NAFLD and serum magnesium level. Results: The average age of the study population was (56.4±13.8) years, males accounted for 52.7%(671/1 273), NAFLD patients accounted for 58.4%(743/1 273). The prevalence of NAFLD in Q₄, Q₃, Q₂ and Q₁ groups was 53.8%(169/314), 52.6%(151/287), 57.4%(170/296) and 67.3%(253/376), respectively (χ²=19.00, P=0.000). Logistic regression showed that compared with the Q₄ group, OR(95%CI) for NAFLD in the Q₁ group was 1.49 (1.03-2.16), P_trend=0.011 after adjusting for age, sex, duration of diabetes, BMI, systolic blood pressure, alcohol consumption, TG, glycosylated hemoglobin and serum uric acid. After further adjusting for estimated glomerular filtration rate (eGFR), OR(95%CI) for NAFLD was 1.33 (0.92-1.94) and P_trend=0.065 in the Q₁ group compared with the Q₄ group. Conclusion Reduction in serum magnesium is associated with an increased risk of NAFLD in T2DM patients, and eGFR may be a confounding factor.

OBJECTIVE: To observe 18β-glycyrrhetinic acid (GA) impact on ultrastructure of tight junctions (TJs) of nasal mucosa epithelial cells in rats models of allergic rhinitis (AR). METHOD: Ninety-six Wistar rats were randomly divided into control group, model group, loratadine group, and 18β-glycyrrhetinic acid group, and each group had 24 rats. Ovalbumin was used to establish a rat AR model. The behavioral changes and the tight junctions of nasal epithelial were observed and compared in different groups after 2,4,6 and 10 weeks intervention. RESULT: The length of TJs in allergic rhinitis model became shorter, electron-high-density plasma membrane became thicker, number of the integration loci reduced and gap of TJs widened or even ruptured. With the consistent effect of allergens,the changes of TJs in the model group aggravated gradually,and the changes of ultrastructure of TJs in 18β-glycyrrhetinic acid group was relieved apparently compared to model group and even were close to the control model with time. CONCLUSION 18β-glycyrrhetinic acid can recover the ultrastructure of the tight junctions of AR rat nasal epithelial cells.

Objective To explore the molecular mechanisms involved in hypokalemic salt-losing tubulopathies ( SLTs) through genetic screening of WNK gene in patients with SLTs. Methods Forty-four kindreds of SLTs were diagnosed Batter's syndrome or Gitelman's syndrome after CLCNKB and SLC12A3 sequencing and analysis, 8 of whose phenotype can not be simply attributed to CLCNKB or SLC12A3 mutations. Primers for PCR-amplified exons of WNK4 and WNK1 gene in genomic DNA were designed, and direct sequencing was performed to analyse the PCR products. Results Two missense mutations of WNK1, Ile~(1172)→ Met (I1172M) and Ser~(2047) → Asn (S2047N), were identified. Both of these 2 mutations segregated with the disease in SLTs kindred. Conclusion Two heterozygote missense mutations of WNK1 gene (I1172 M and S2047N) were found in 8 SLTs kindreds, indicating that WNK1 might be another gene responsible for hypokalemic salt-losing tubulopathies.
