Objective To observe the effects of hemoperfusion(HP)combined with hemodialysis on cholinesterase(ChE)activity and inflammatory factors in patients with acute organophosphorus pesticide poisoning(AOPP).Methods A retrospective cohort study was conducted.Seventy-three AOPP patients admitted to the department of emergency of Yingshang People's Hospital from January 2020 to December 2022 were enrolled.The patients were divided into HP group(31 cases)and HP+continuous renal replacement therapy(CRRT)group(42 cases)according to different treatment regimens.All patients were given supportive treatment according to the standard protocol after admission.HP was given to the patients as soon as possible after admission,and the treatment time was between 2 hours and 3 hours,with an interval of 24 hours.Patients in HP+CRRT group were treated with continuous veno-venous hemodiafiltration(CVVHDF)after HP.The serum ChE,tumor necrosis factor-α(TNF-α),and interleukins(IL-1,IL-6)levels were compared between the two groups after admission(T0),at the end of the first HP/HP+CRRT(T1),at the end of the second HP/HP+CRRT(T2),and at the end of the third HP/HP+CRRT(T3).The ChE recovery time,the incidence of intermediate syndrome(IMS),the length of hospital stay,and the rate of admission to ICU were also compared.Results With the extension of treatment time,the ChE activity at T1,T2,and T3 in the two groups was significantly higher than that at T0,and the levels of TNF-α,IL-1,and IL-6 were significantly lower than those at T0,reaching the trough value at T3,and the changes in HP+CRRT group were more significant than those in HP group[ChE activity(U/L):2 903.26±164.43 vs.2 292.98±350.96,TNF-α(ng/L):78.24±10.75 vs.100.55±15.58,IL-1(ng/L):95.98±22.56 vs.127.94±18.74,IL-6(ng/L):34.36±8.66 vs.58.74±10.46,all P<0.05].The recovery time of ChE activity and length of hospital stay in HP+CRRT group were significantly shorter than those in HP group[ChE activity recovery time(days):4.42±1.17 vs.7.31±1.46,length of hospital stay(days):9.25±2.14 vs.12.75±2.30,both P<0.05],the incidence of IMS and ICU admission rate were significantly lower than those in HP group[the incidence of IMS:33.33%(14/42)vs.61.29%(19/31),ICU admission rate:9.52%(4/42)vs.29.03%(9/31),both P<0.05].Conclusion For AOPP patients,HP+CRRT is superior to HP alone in the clearance of inflammatory factors,restoring ChE activity,reducing the incidence of IMS,and shortening the length of hospital stay,making it a valuable option for clinical application.

Diabetic kidney disease is an important microvascular complication of diabetes and the leading cause of end-stage renal disease. Its pathological characteristics mainly include epithelial mesenchymal transition(EMT) in glomerulus, podocyte apoptosis and autophagy, and damage of glomerular filtration barrier. Transforming growth factor-β(TGF-β)/Smad signaling pathway is specifically regulated by a variety of mechanisms, and is a classic pathway involved in physiological activities such as apoptosis, proliferation and differentiation. At present, many studies have found that TGF-β/Smad signaling pathway plays a key role in the pathogenesis of diabetic kidney disease. Traditional Chinese medicine has significant advantages in the treatment of diabetic kidney disease for its multi-component, multi-target and multi-pathway characteristics, and some traditional Chinese medicine extracts, traditional Chinese medicines and traditional Chinese medicine compound prescription improve the renal injury of diabetic kidney disease by regulating TGF-β/Smad signaling pathway. This study clarified the mechanism of TGF-β/Smad signaling pathway in diabetic kidney disease by expounding the relationship between the key targets of the pathway and diabetic kidney disease, and summarized the research progress of traditional Chinese medicine in the treatment of diabetic kidney disease by interfering with TGF-β/Smad signaling pathway in recent years, to provide reference for drug research and clinical treatment of diabetic kidney disease in the future.

OBJECTIVE: This study aimed to reveal the insomnia burden and relevant influencing factors among informal caregivers (ICs) of hospitalized patients with lung cancer. METHODS: A cross-sectional study on ICs of hospitalized patients with lung cancer was conducted from December 31, 2020 to December 31, 2021. ICs' burden was assessed using the Caregiver Reaction Assessment (CRA), Hospital Anxiety and Depression Scale (HADS), and Insomnia Severity Index (ISI). Linear and logistic regression models were used to identify the influencing factors. RESULTS: Among 289 ICs of hospitalized patients with lung cancer, 83 (28.72%), 53 (18.34%), and 14 (4.84%) ICs experienced mild, moderate, and severe insomnia, respectively. The scores concerning self-esteem, lack of family support, financial problems, disturbed schedule, and health problems were 4.32 ± 0.53, 2.24 ± 0.79, 2.84 ± 1.14, 3.63 ± 0.77, and 2.44 ± 0.95, respectively. ICs with higher Activities of Daily Living Scale (ADLS) scores were associated with a lower risk of insomnia, with an odd ratio ( OR) and 95% confidence interval ( CI) of 0.940 (0.898-0.983). Among the ICs, female gender ( OR = 2.597), alcohol consumption ( OR = 3.745), underlying medical conditions ( OR = 11.765), long-term caregiving experience ( OR = 37.037), and higher monthly expenses ( OR = 5.714) were associated with a high risk of insomnia. CONCLUSION Of the hospitalized patients with lung cancer, 51.9% experienced insomnia. Patients' ADL, ICs gender, alcohol consumption, underlying medical conditions, caregiving duration, and monthly expenses were influencing factors. Therefore, prompt screening and early intervention for ICs of patients with lung cancer is necessary.

AIM: To investigate the differences of myopia and ocular biological parameters of primary and middle school students in Urumqi.METHODS: A cross-sectional survey. A total of 2 495 primary and middle school students aged 7 to 18 from 4 schools in Urumqi were selected by judgemental sampling from September 2021 to November 2021 for relevant eye examination. The differences of ocular biological parameters and refractive status of students of different ages, genders and nationalities were compared, and the correlation between spherical equivalent(SE)and ocular biological parameters was analyzed.RESULTS: The detection rate of poor vision among the students was 80.36%, the detection rate of myopia was 55.91%, and the detection rate of astigmatism was 42.96%, among which the detection rate of low myopia was 63.80%, the detection rate of moderate myopia was 27.60%, and the detection rate of high myopia was 8.60%. There were significant differences in the detection rate of poor vision, myopia, astigmatism, SE and some ocular biological parameters among students of different ages and nationalities(all P<0.05). Among them, the detection rate of myopia, astigmatism and poor vision among Uygur and Kazakh ethnic groups was significantly lower than that of Han. The detection rate of poor vision and myopia among boys was lower than that among girls, while the detection rate of astigmatism was higher than that of girls. Spearman correlation analysis showed that axis length of eye, axial length to axial ratio, anterior chamber depth, and pupil diameter were negatively correlated with SE(rs=-0.664, -0.724, -0.320, -0.086, all P<0.001), and lens thickness was positively correlated with SE(rs=0.147, P<0.001).CONCLUSION: The prevalence of myopia among primary and secondary school students in Urumqi is high, and there are differences in the distribution of ocular biological parameters among children and adolescents of different ages and ethnicities.

AIM: To investigate the correlation between the ocular demodex infection and the composition of meibum lipid flora.METHODS: A non-interventional and observational study was performed on recruited 39 patients in our hospital between July 2020 and February 2021. They were divided into control group(n=14), meibomian gland dysfunction(MGD)group(n=14), and demodex group(FM, n=11)according to the presence or absence of demodex infection or MGD. High-throughput sequencing of V3-V4 fragment of 16S rRNA gene was performed on the meibomian ester samples of the three groups of subjects, and bioinformatics analysis was performed on the sequencing data to study the composition and difference of meibum lipid flora in the subjects of ocular demodex.RESULTS: Pseudomonas and Comamonas in FM group were significantly higher than those in control group and MGD group(P<0.05), while Ralstonia in Demodex infection group was significantly lower than that in control group and MGD group(P<0.05). The microbial richness and community diversity of meibum lipid flora of the MGD group and the FM group were significantly higher than those of the control group(P<0.05).CONCLUSION: Ocular demodex infection changed the composition of meibum lipid flora and increased the microbial richness and community diversity of meibum lipid flora.

OBJECTIVE: To investigate the relationship between single nucleotide polymorphisms (SNPs) of IKAROS family Zinc finger 3 (IKZF3) gene and the risk of acute lymphoblastic leukemia (ALL) in children. METHODS: The peripheral blood samples from 286 children with ALL and 382 healthy children were collected and divided into ALL group and control group, respectively. The genotypes of IKZF3 gene at rs62066988 C > T and rs12946510 C > T were detected by quantitative PCR with TaqMan detection system, and their correlation with ALL was analyzed. RESULTS: The distribution frequencies of CC, CT and TT genotypes at rs62066988 in ALL group were 58.39%, 37.06% and 4.55%, respectively, while those in control group were 69.19%, 27.68% and 3.13%, respectively. The distribution frequencies of CC, CT and TT genotypes at rs12946510 in ALL group were 58.16%, 34.75% and 7.09%, respectively, while those in control group were 55.76%, 37.43% and 6.81%, respectively. Compared with the control group, the distribution frequency of CT/TT genotype at rs62066988 was significantly increased in the ALL group (OR=1.59, 95%CI: 1.16-2.19, P=0.004). However, there was no significant difference in the distribution of rs12946510 C > T polymorphism between ALL group and control group. CONCLUSION The CT/TT genotype of IKZF3 at the site of rs62066988 is associated with the increased risk of ALL in children.

OBJECTIVE: To study the effect and mechanism of action of irisin on hypoxic-ischemic brain damage in neonatal rats. METHODS: A total of 248 7-day-old Sprague-Dawley rats were randomly divided into a sham-operation group, a model group, and low- and high-dose irisin intervention groups (n=62 each). The rats in the model and irisin intervention groups were given hypoxic treatment after right common carotid artery ligation to establish a model of hypoxic-ischemic brain damage. Those in the sham-operation group were given the separation of the right common carotid artery without ligation or hypoxic treatment. The rats in the high- and low-dose irisin intervention groups were given intracerebroventricular injection of recombinant irisin polypeptide at a dose of 0.30 µg and 0.15 µg respectively. Those in the model and sham-operation groups were given the injection of an equal volume of PBS. The water maze test was used to compare neurological behaviors between groups. TTC staining, hematoxylin-eosin staining and TUNEL staining were used to observe histopathological changes of the brain. Western blot was used to measure the expression of the apoptosis-related molecules cleaved-caspase-3 (CC3), BCL-2 and BAX. RESULTS: Compared with the sham-operation group, the model group had a significant increase in latency time and a significant reduction in the number of platform crossings (P<0.05). Compared with the model group, the high-dose irisin intervention group had a significant reduction in latency time and a significant increase in the number of platform crossings (P<0.05). Compared with the sham-operation group, the model group had massive infarction in the right hemisphere, with significant increases in karyopyknosis and karyorrhexis. Compared with the model group, the high-dose irisin intervention group had a smaller infarct area of the right hemisphere, with reductions in karyopyknosis and karyorrhexis. The model group had a significantly higher apoptosis rate of cells in the right cerebral cortex and the hippocampus than the sham-operation group. The high-dose irisin intervention group had a significantly lower apoptosis rate than the model group (P<0.05). At 24 and 48 hours after modeling, the sham-operation group had a significantly lower level of CC3 than the model group (P<0.05). Compared with the model group, the high-dose irisin intervention group had a significantly lower level of CC3 and a significantly higher BCL-2/BAX ratio (P<0.05). The low-dose irisin intervention group had similar laboratory markers and histopathological changes of the brain to the model group. CONCLUSIONS Irisin can alleviate hypoxic-ischemic brain damage in neonatal rats in a dose-dependent manner, possibly by reducing cell apoptosis in the cerebral cortex and the hippocampus.

OBJECTIVE: To investigate the expression level of miR-181b in CD19+ B lymphocytes of patients with chronic lymphocytic leukemia (CLL), to analyze the relationship between its expression and the prognosis of CLL patients, and to predict the potential target gene of miR-181b in CLL by using bioinformatics. METHODS: Eight-four patients with CLL treated in People's Hospital of Xinjiang Uygur Autonomous Region from June 2013 to June 2018 were selected. and 20 healthy people were selected as control group. RNA was extracted from CD19+B lymphocytes of peripheral blood by magnetic bead sorting, the expression level of miR-181b was detected, and it's expression differences in different IPI groups were analyzed. The correlation between the expression level of miR-181b and PFS of CLL patients also was analyzed. miR-181b target genes were predicted by online database and literatures, and gene annotation analysis and relevant signal pathway analysis were performed for candidate target genes. RESULTS: The expression level of miR-181b in CLL patients was significantly lower than that in control group (P＜0.01); The expression level of miR-181b in the low-risk group was higher than that in high-risk group and extremely high-risk group (P＜0.05), but there was no statistical difference between low-risk group and medium-risk group (P=1.00). The expression level of miR-181b in medium-risk group was higher than that in high-risk group and extremely high-risk group (P＜0.05), but there was no difference between high-risk group and extremely high-risk group (P=1.00). ROC curve results showed that the area under the curve (AUC) was 0.792 (P＜0.01).When the expression level of miR-181b was at the threshold value of 0.279, it showed a better sensitivity (62.9%) and specificity (91.8%). Survival analysis results suggested that compared with the high expression group, the miR-181b low expression group had poor PFS (log rank: P=0.047). Prediction of miR-181b by using the starBase, targetscan and picTar database and its combination with literature reports indicated that CARD11, ZFP36L1, RUNX1, NR4A3, ATP1B1, PUM1 and PLAG1 related with blood diseases, and up-regulated CARD11 and ZFP36L1 participated in lymphoid tumor formation by promoting cell proliferation and inhibiting cell aging. CONCLUSION The expression level of miR-181b in CLL group are significantly lower than that in the controls group, and the low expression of miR-181b relates with poor prognosis of CLL patients. Through bioinformatics prediction and combined with literature reports, it is speculated that CARD11 and ZFP36L1 as target genes of miR-181b may be participated in the occurrence and development of CLL. Further experiments are needed to verify this result.
