Objective To investigate the associations of shear wave elastography (SWE) parameters and AST-to-platelet ratio index (APRI) with Child-Pugh grade in patients with hepatitis B cirrhosis. Methods The clinical data of 103 patients with hepatitis B cirrhosis who underwent SWE and APRI testing between July 2022 and October 2024 were retrospectively analyzed. These patients comprised the observation group. The clinical data of 99 non-cirrhotic patients were retrospectively analyzed and the patients were enrolled as control group. Liver stiffness (LS), spleen stiffness (SS), APRI and Child-Pugh score were compared in the two groups. According to Child-Pugh grading, the 103 cirrhosis patients were divided into three groups: Group A (grade A, 5-6 points, n=35), Group B (grade B, 7-9 points, n=38), and Group C (grade C, 10-15 points, n=30). SWE parameters and APRI were compared among the three groups. Pearson correlation analysis was used to examine the correlations of LS, SS, and APRI with Child-Pugh score. Results SWE parameters, APRI, and Child-Pugh scores were significantly higher in the observation group than in the control group (P<0.05). Among the three cirrhosis groups, SWE parameters and APRI were highest in Group C, followed by Group B, and lowest in Group A (P<0.05). SWE parameters and APRI were significantly positively correlated with Child-Pugh score (P<0.05). Conclusion SWE parameters and APRI are positively correlated with Child-Pugh grade and are useful for assessing the severity of liver cirrhosis.

Objective:To evaluated the efficacy and safety of eltrombopag in patients with systemic lupus erythematosus (SLE)-related refractory immune thrombocytopenia (ITP).Methods:Nine patients with severe SLE-associated refractory ITP were recruited the People's Hospital of Xinjiang Uygur Automomous Region from Septermber 2021 to February 2024 and received eltrombopag 50 mg orally daily for 1 month; basic patient information, platelet counts, other laboratory parameters and adverse events were recorded. Normally distributed continuous data were expressed as mean±standard deviation ( Mean±SD) and compared using paried samples t-test; non-normally distributed data were presented as median (interquartile range) [ M( Q1, Q3)]; categorical variables were described as n (%). Results:Eight participants (88.9%) completed the study, and at 1 month, five patients showed significant improvement in subcutaneous bleeding and erythema of the skin and mucous membranes, and three patients showed significant relief of joint and muscle involvement, and the patients′ platelet counts were (16.9±9.6)×10 9/L before treatment and increased to (114.0±53.9)×10 9/L. Differences in platelet levels before and after treatment in intergroup comparisons ( t=-4.881 , P=0.002), of which 4 patients achieved complete remission of platelet involvement, 3 patients achieved partial remission of platelet involvement, 4 cases were significantly efficacious and 3 cases efficacious. Follow-up data showed that platelet counts remained normal with no significant adverse events and one patient discontinued the study after 2 weeks of eltrombopag due to abnormal blood counts. Conclusion:Eltrombopag may be a promising new option for patients with SLE-associated refractory ITP with satisfactory remission rates, but large sample studies are needed for validation.

Objective To analyze the risk factors for extrauterine growth retardation(EUGR)in late preterm infants appropriate for gestational age.Methods The clinical data in 1 402 preterm infants appropri-ate for gestational age delivered and hospitalized in this hospital from January 2016 to June 2022 were analyzed retrospectively.They were divided into the EUGR group(n=244)and the non-EUGR group(n=1 158)ac-cording to whether or not the body weight at discharge was below the 10th percentile of the growth curve for the same gestational age at the same period based on the Fenton's preterm growth curve.The clinical data of preterm infants and mothers of the two groups were collected.The risk factors for EUGR occurrence in pre-mature infants were analyzed.Results Among 1 402 preterm infants appropriate for gestational age,EUGR occurred in 244 cases with the EUGR incidence rate of 17.4％.The EUGR incidence rate had no statistical difference among the different fetal ages of premature infants(P＞0.05).The EUGR incidence rate had sta-tistical difference among different birth weights of premature infants(P＜0.05).The logistic regression anal-ysis showed that male(OR=1.694,95％CI:1.144-2.507),low birth weight(OR=0.989,95％CI:0.988-0.991),feeding intolerance(OR=2.719,95％CI:1.234-5.990),short gestational weeks(OR=0.146,95％CI:0.103-0.207)and hospitalization duration extension(OR=1.073,95％CI:1.031-1.117)were the risk factors for EUGR occurrence in late premature infants appropriate for gestational age in discharge.The sub-group analysis showed that male,low birth weight,feeding intolerance and hospitalization duration extension were the risk factors for EUGR occurrence in the preterm infants with gestational ages of 34-＜36 weeks(P＜0.05).Low birth weight and feeding intolerance only affected the preterm infants≥36 weeks of gesta-tional age(P＜0.05).Conclusion Strengthening the pregnant duration health care and active nutritional sup-port after birth may reduce the risk of EUGR occurrence in late premature infants.

Objective To investigate the role of Rho/Rock signaling pathways in ventilator-in-duced lung injury in rats.Methods Ninety-six male SD rats,weighing 300-350 g,were equally and randomly divided into four groups using a random number table (n =24 each):control group (group C),fasudil group (group F),high tidal volume group (group H)and high tidal volume + fasudil group (group HF).Rats in group C and group F received no mechanical ventilation,rats in group H and group HF were intubated and mechanically ventilated (VT = 40 ml/kg,RR = 40 beats per minutes,FiO 2 =40%)for 4 h.The animals in group F and group HF were given intraperitoneal in-jection of fasudil 10 mg/kg at the time 1 h before mechanically ventilated.Six rats were chosen in each group at the time before ventilation (T0 )and at 4,8,24 h after ventilation (T1-T3 ),and blood sam-ples were taken for determination of the levels of serum tumor necrosis factor-α (TNF-α),IL-6 and IL-10,lungs were removed,bronchoalveolar lavage fluid (BALF)was collected to examine protein content,wet/drying (W/D)ratio was determined,which were then stained with haematoxylin and e-osin and examined under microscope,the pathological changes of lungs were scored.Myeloperoxidase (MPO)activity in lung tissue was determined by spectrophptometry.Protein and gene expression of RhoA and Rock2 in the lung tissue were detected by Western blot and reverse transcription PCR (RT-PCR).Results Compared with group C,the serum TNF-α,IL-6 and IL-10,BALF protein content, W/D ratio,the pathological scores,MPO activity,the expression of RhoA,Rock2 protein and mR-NA were significantly increased in group H and HF at T1-T3 (P <0.05 ).Compared with group H, the serum TNF-αand IL-6,BALF protein content,W/D ratio,the pathological scores,MPO activi-ty,the expression of RhoA,Rock2 protein and mRNA were significantly decreased,and the serum IL-10 was significantly increased in group HF at T1-T3 (P <0.05).Conclusion Fasudil can attenuate ventilator-induced lung injury in rats,and the mechanism may be associated with inhibition of the Rho/Rock signaling pathways reducing the inflammatory response.
