Objective To investigate the association of triglyceride-glucose index(TyG)with non-alcoholic fatty liver disease(NAFLD)and its diagnostic value for NAFLD in non-obese individuals.Methods We retrospectively collected the data of non-obese individuals(BMI<25 kg/m2)undergoing routine health examination at Second Affiliated Hospital of Xi'an Jiaotong University between May,2020 and December,2023,who all received abdominal ultrasound examination for NAFLD screening.The nonlinear relationship between TyG and non-obese NAFLD was explored using restricted cubic splines(RCS),and LASSO regression was used for variable screening;the correlation between TyG and NAFLD risk was analyzed using multivariate logistic regression.The diagnostic value of TyG for non-obese NAFLD was assessed using receiver-operating characteristic(ROC)curves and sensitivity analysis.Results A total of 3723 non-obese subjects were enrolled in this study,including 432(11.6%)patients with NAFLD.Compared with the healthy individuals,the patients with NAFLD had significant elevations of systolic and diastolic blood pressures,total cholesterol,triglycerides,LDL-C,blood uric acid,fasting blood glucose,and TyG index and a decreased HDL-C level(P<0.05).Multivariate logistic regression revealed that for each one-unit increase of TyG,the risk of non-obese NAFLD increased by 2.2 folds(OR=3.22,95%CI:2.53-4.12,P<0.001).Compared with a TyG index in the lowest quartile Q1,a TyG index in the Q2,Q3 and Q4 quartiles was associated with an increased risk of NAFLD by 1.52 folds(OR=2.52,95%CI:1.20-5.95),3.56 folds(OR=4.56,95%CI:2.28-10.46),and 8.66-folds(OR=9.66,95%CI:4.83-22.18),respectively.The RCS curve demonstrated a significant linear correlation between TyG index and non-obese NALFD risk(P for nonlinear=0.019).For diagnosing non-obese NALFD,TyG index had an area under ROC curve of 0.819 with a sensitivity of 78.0%and a specificity of 71.2%.Conclusion An increase of TyG index is correlated with increased risks of NAFLD in non-obese individuals and can serve as an indicator for screening early NAFLD in healthy individuals.

OBJECTIVE To evaluate the palatability and chewability of chewable tablets， and provide reference for the quality evaluation of various types of chewable tablets. METHODS Using self-made Glucosamine hydrochloride chewable tablets as the model drug， the quality test was conducted. The in vitro simulation system for chewable tablets was established by using a texture analyzer and rheometer， and an oral simulation experiment was conducted on chewable tablets. The texture analyzer was used to measure the force required for chewing and simulate the static disintegration process of chewable tablets； the rheometer was adopted to measure the viscoelasticity， thixotropy， and deformability of chewable tablets during the chewing process. RESULTS The disintegration time limit， principal component content， and dissolution of self-made Glucosamine hydrochloride chewable tablets all met the limit requirements. The in vitro simulation results of the texture analyzer showed that self-made chewable tablets were easy to chew in both axial and radial directions， and the force required for chewing was within the range of the chewing force of the teeth； chewable tablets could disintegrate at an appropriate time without being chewed and only taken in the oral cavity. The in vitro simulation results of the rheometer showed that the chewable tablets in the oral cavity exhibited a behavior of elasticity as the main factor and viscosity as the secondary factor through the continuous stirring of the tongue， and the viscosity of the chewable tablets gradually decreased with tongue stirring or tooth chewing； when chewing with teeth， the internal force of the chewing tablets decreased， causing plastic deformation and crushing. After being crushed， the shape couldn’t be restored， making it easy to chew and swallow. CONCLUSIONS The combination of texture analyzer and rheometer can be used to simulate the oral chewing process and evaluate the palatability and chewability of self-made Glucosamine hydrochloride chewable tablets. This model can provide reference for the evaluation of various chewable tablets.

[Purpose]To analyze the incidence and mortality trends,and survival of gallbladder cancer in Nantong City of Jiangsu Province from 2013 to 2017.[Methods]The gallbladder cancer incidence and mortality data from 2013 to 2017 were collected from Nantong cancer registries.The crude incidence/mortality rates,age-standardized incidence/mortality rates by Chinese and world standard population(ASIRC/ASMRC,ASIRW/ASMRW)were calculated by sex,age and regions(urban and rural).Joinpoint software was used to analyze the incidence and mortality trends of gallbladder cancer.The observed survival rate and relative survival rate were calculated by using life table method and Ederer Ⅱ method.[Results]From 2013 to 2017,the gallbladder cancer crude incidence and mortality rates were 6.36/105 and 4.91/105,ASIRC and ASMRC were 2.62/105 and 1.94/105,respectively.The crude incidence and mortality,and ASMRC showed an upwards trend(all P＜0.05).The ASIRC for men and women was 2.43/105 and 2.83/105,the ASMRC for men and women was 1.74/105 and 2.16/105,respectively.ASIRC and ASMRC in women were higher than those in men.The ASIRC in urban and rural areas was 2.40/105 and 2.69/105,and the ASMRC was 1.61/105 and 2.05/105,respectively.ASIRC and ASMRC in rural areas were higher than those in urban areas.The average age of onset was 70.33 years old and the average age of death was 71.86 years old.The 5-year observed survival rate was 12.90％,and the 5-year relative survival rate was 14.47％.Both the 5-year observed survival rate and relative survival rate showed an upwards trend(both P＜0.05).[Conclusion]The incidence and mortality rates of gall-bladder cancer in Nantong City are relatively high and the survival rate is generally low.It is sug-gested that targeted prevention and control measures of gallbladder cancer in Nantong City should be strengthened,particularly in rural areas and for middle-aged and elderly women.

Objective To observe the difference and clinical significance of expression levels of microRNA-155(miR-155)mRNA and interleukin-6(IL-6)in very preterm neonates with preeclampsia.Methods Twenty-eight cases of very preterm newborns(gestational age<32 weeks and/or body weight<1500 g)from preeclampsia pregnant women admitted to the department of obstetrics of Liaocheng People's Hospital from January to December 2021 were selected as the observation group,and 26 cases of very preterm neonates hospitalized for other reasons during the same period were selected as the control group.Electronic medical record clinical data related to children were collected,and the differences between the two groups were compared,including general conditions of preterm infants and pregnant mothers(gender,gestational age,birth weight,preeclampsia or not),proportion of invasive ventilation,proportion of bronchopulmonary dysplasia(BPD),incidence of acute respiratory distress syndrome(ARDS)and early-onset sepsis,white blood cell count(WBC),neutrophil count(NEUT),and expression of miR-155 mRNA and IL-6 levels in the serum of umbilical arterial blood after birth.Pearson correlation analysis was used to analyze the correlation between miR-155 and IL-6 levels Results The birth body weight of the observation group was significantly lower than that of the control group(kg:1.21±0.22 vs.1.32±0.33,P<0.05),the proportion of invasive ventilation,the proportion of BPD,the incidence of ARDS and sepsis were significantly higher than those in the control group[the proportion of invasive ventilation:75.0%(21/28)vs.57.7%(15/26),the proportion of BPD:35.7%(10/28)vs.11.5%(3/26),incidence of ARDS:100.0%(28/28)vs.84.6%(22/26),incidence of sepsis:71.4%(20/28)vs.53.8%(14/26),all P<0.05],the level of miR-155 mRNA expression and IL-6 were significantly higher than those in the control group[miR-155 mRNA(2-ΔΔCt):0.93±0.18 vs.0.17±0.03,IL-6(ng/L):73.84(33.44,429.00)vs.19.05(9.30,47.20),both P<0.05].Pearson correlation analysis showed that miR-155 and IL-6 levels were significantly positively correlated(r=0.782,P<0.01).With the extension of birth time,both WBC and NEUT gradually decreased in the two groups,and there were statistically significant differences in WBC and NEUT at each time point after birth,with counts significantly lower at 48 hours and 72 hours compared to 24 hours after birth(both P<0.05).The WBC of the observation group at 24,48 and 72 hours after birth was significantly lower than that of the control group(×109/L:7.85±2.44 vs.12.28±6.81 at 24 hours after birth,7.31±3.53 vs.10.98±7.91 at 48 hours after birth,4.97±2.05 vs.7.82±4.65 at 72 hours after birth,all P<0.05),NEUT in observation group was significantly lower than of control group at 24 hours and 48 hours after birth(×109/L:24 hours after birth was 4.13±1.93 vs.7.45±5.67,48 hours after birth was 3.96±2.64 vs.6.89±6.24,both P<0.05).Conclusion The expression level of miR-155 mRNA and IL-6 in very preterm neonates with preeclampsia is significantly up-regulated at the time of birth,and the inflammatory response of the body is disturbed,which has certain value for early assessment of the disease.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the correlation between serum long non-coding RNA FGD5-AS1(ln-cRNA FGD5-AS1),microRNA-103a-3p(miR-103a-3p)and puerperal infection(PI)in patients with gesta-tional diabetes mellitus(GDM)in late pregnancy.Methods A total of 168 late pregnancy GDM patients who were hospitalized and delivered in the hospital from January 2022 to June 2023 were retrospectively selected as the experimental group,and the patients were separated into an infected group(96 cases)and an uninfected group(72 cases)based on whether they had PI.At the same time,120 late pregnant women who underwent prenatal examination in the hospital and had normal gestational blood glucose were selected as the control group.Real-time fluorescence quantitative PCR(qRT-PCR)was applied to detect the expression levels of ln-cRNA FGD5-AS1 and miR-103a-3p.Multivariate Logistic regression was applied to analyze the influencing factors of PI in late pregnancy GDM patients.StarBase website was applied to analyze the relationship between lncRNA FGD5-AS1 and miR-103a-3p.Pearson was applied to analyze the correlation between lncRNA FGD5-AS1 and miR-103a-3p.Receiver operating characteristic(ROC)curve was applied to evaluate the value of ln-cRNA FGD5-AS1 and miR-103a-3p in predicting the occurrence of PI.Results There was a statistically sig-nificant difference in the expression levels of serum lncRNA FGD5-AS1 and miR-103a-3p between the experi-mental group and the control group(P＜0.05),the expression level of serum lncRNA FGD5-AS1 in the infec-ted group was obviously higher than that in the uninfected group(P＜0.05),but the expression level of ser-um miR-103a-3p in the infected group was obviously lower than that in the uninfected group(P＜0.05).The expression level of lncRNA FGD5-AS1 was an independent risk factor for PI in late-pregnancy GDM patients(P＜0.05),and the expression level of miR-103a-3p was an independent protective factor for PI in late-preg-nancy GDM patients(P＜0.05).There was a negative correlation between lncRNA FGD5-AS1 and miR-103a-3p expression level(r=-0.409,P＜0.001).The efficacy of the combined detection of lncRNA FGD5-AS1 and miR-103a-3p for predicting PI in late pregnancy GDM patients was superior to that of serum lncRNA FGD5-AS1 and miR-103a-3p alone(P＜0.05).Conclusion LncRNA FGD5-AS1 is an independent risk factor for PI in late pregnancy GDM patients,while miR-103a-3p is an independent protective factor for PI in late pregnancy GDM patients.The combined detection has higher value for predicting PI in late pregnancy GDM patients.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.
