Objective To investigate the prevalence of spotted fever group rickettsiae (SFGR) infections in free-living ticks and among high-risk populations in the southern margin of the Gurbantunggut Desert, Xinjiang Uygur Autonomous Region, so as to provide insights into tick-borne diseases prevention and control in this region. Methods Free-living ticks were collected from five counties (cities) in the southern margin of the Gurbantunggut Desert, Xinjiang Uygur Autonomous Region. Tick species were identified by morphology combined with mitochondrial cytochrome c oxidase subunit Ⅰ (COI) gene analysis. Four target gene fragments of Rickettsia were amplified using a nested PCR assay, including outer membrane protein B (ompB), 17-kDa common surface antigen protein (17kDa), surface cell antigen 1 (sca1), and surface cell antigen 4 (sca4) genes, to detect the prevalence of SFGR infections in tick samples. Positive PCR amplification products were purified, sequenced, and subjected to sequence alignment, and phylogenetic trees were created using the neighbor-joining (NJ) method. Serum samples were collected from individuals at a high risk of tick exposure from six counties (cities, districts) in the southern margin of the Gurbantunggut Desert, Xinjiang Uygur Autonomous Region, and serum levels of anti-R. sibirica IgG antibodies were detected among these individuals using indirect immunofluorescence assay (IFA) and statistically analyzed. Results A total of 287 free-living ticks were collected, and all were identified as Hyalomma asiaticum. The overall prevalence of SFGR infection was 78.40% (225/287) in tick samples, and five Rickettsia species were characterized, including R. sibirica, which shared 99.81% (515/516) sequence homology with the strain detected in Dermacentor sinicus from China; R. massiliae, which shared 99.80% (509/510) sequence homology with the strain detected in Rhipicephalus sanguineus from Ethiopia; R. raoultii, which shared 100.00% (516/516) sequence homology with the strain detected in Hyalomma asiaticum from Xinjiang Uygur Autonomous Region in China; R. africae, which shared 100.00% (524/524) sequence homology with the strain detected in Amblyomma splendidum from Ethiopia; and Candidatus Rickettsia barbariae, which shared 99.80% (499/500) sequence homology with the strain detected in steppe polecats from Xinjiang Uygur Autonomous Region in China, with R. sibirica (33.80% detection rate, 97/287) and R. raoultii (33.10%, 95/287) as dominant species. A total of 1 489 serum samples were collected from individuals at a high risk of tick exposure, and the seroprevalence of antiR. sibirica IgG antibodies was 30.83% (459/1 489). There were no significant differences in the seroprevalence in terms of genders (χ² = 2.23, P > 0.05) or age groups (χ² = 6.45, P > 0.05); however, there was a region-specific seroprevalence rate of anti-R. sibirica IgG antibodies (χ² = 16.05, P < 0.05). Pairwise comparisons showed lower seroprevalence rate of anti-R. sibirica IgG antibodies among high-risk individuals in Midong District of Urumqi City (22.27%, 53/238) than in Wujiaqu City (34.70%, 93/268) and Manas County(37.55%, 98/261) (both P values < 0.05); however, they were not significantly different from those in the other regions (all P values > 0.05). Conclusion Multiple SFGR species are detected in H. asiaticum ticks sampled from the southern margin of the Gurbantunggut Desert, Xinjiang Uygur Autonomous Region, where there is a potential risk of local transmission of spotted fever rickettsiosis.

Objective To investigate the association between UGT1A1 inhibitors-induced liver injury(DILI)and UGT1A1 gene polymorphisms through a pharmacogenomics approach.Methods Information on relevant drugs that may induce liver injury,blood routine tests,and liver function tests was collected from hospitalized patients diagnosed with DILI between June 2022 and June 2024.Relevant databases were searched to categorize DILI-associated drugs into UGT1A1 enzyme inhibitors and those without interaction with UGT1A1.Sanger sequenc-ing or MassARRAY SNP typing technology was utilized to detect and genotype the UGT1A1 gene.Results A total of 219 patients with drug-induced liver injury(DILI)were enrolled,including 98 males,with a mean age of 46.32±14.95 years.A literature search of relevant databases revealed that 20 drugs(16.26%,20/123)associated with DILI had inhibitory effects on the UGT1A1 enzyme.The proportion of DILI cases related to UGT1A1 inhibitors was 60.73%(133/219).Compared to non-UGT1A1 inhibitor-related DILI group,the UGT1A1 inhibitor-related DILI group exhibited significantly higher levels of ALT,AST,ALP,and GGT(P<0.05),while no significant differences were observed in age,gender,TBIL,IBIL,WBC,Hb,PLT,injury type,or injury grade(P>0.05).The prevalence of UGT1A1 polymorphisms was significantly higher in the UGT1A1 inhibitor-related DILI group(68.42%)com-pared to the non-UGT1A1 inhibitor-related DILI group(51.16%),with an odds ratio(OR)of 2.068(95%CI:1.183 to 3.617;χ2=6.58,P=0.010).There was also a significant difference in the distribution of genotypes between the UGT1A1 inhibitor-related and non-UGT1A1 inhibitor-related DILI groups(χ2=9.60,P=0.022).Univariate logistic regression analysis indicated that ALT and UGT1A1*6 were associated with UGT1A1 inhibitor-related DILI,while multivariate analysis confirmed that UGT1A1*6 was independently associated with UGT1A1 inhibitor-related DILI[OR(95%CI)=3.143(1.398 to 7.067),P=0.006].Conclusion The UGT1A1*6 allele increases the susceptibility to drug-induced liver injury(DILI)associated with UGT1A1 inhibitory drugs.

Objective: To explore the effects of long non-coding RNA (LncRNA) MIR22HG on proliferation，apoptosis and inflammatory response of rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLSs) and its molecular mechanism． Methods: Synovial tissue samples were collected from 37 RA patients and 30 joint trauma patients in our hospital，and the expression levels of MIR22HG and miR-22-5p in synovial tissue were detected by qRT-PCR. RA-FLSs in human was isolated ，cultured and identified in vitro． MIR22HG siRNA interference plasmid (si-MIR22HG) and its negative control plasmid (si-NC) ，miR-22-5p inhibitor and its negative control (inhibitorNC) were transfected into RA-FLSs respectively or simultaneously．The expression levels of MIR22HG and miR- 22-5p were detected by qRT-PCR. CCK-8 was used to detect the proliferation activity of cells in various groups. Annexin Ⅴ- FITC / PI was used to detect the apoptosis rates of cells in various groups．ELISA was used to detect the levels of TNF-α , IL-1 β and IL-6 in the supernatant of cells in various groups．Western blot was used to detect the protein expression levels of Bcl-2，Bax and Cleaved caspase-3 of cells in various groups．The targeting relationship between MIR22HG and miR-22-5p was verified by dual luciferase reporter gene assay. Results : Compared with joint trauma patients，the expression level of MIR22HG in synovial tissues of RA patients increased (P＜0. 05) ， while the expression level of miR-22-5p decreased (P＜0. 05) ．Interference with MIR22HG inhibited the proliferation activity of RA-FLSs，decreased the levels of TNF-α , IL-1 β and IL-6 in cell supernatant and the protein expression level of Bcl-2 in cells (P＜0. 05) ，and increased the apoptosis rate，the expression level of miR-22-5p and the protein expression levels of Bax and Cleaved casepase-3 (P ＜0. 05 ) ．However，inhibition of miR-22-5p expression reversed the effects of MIR22HG gene silencing on proliferation，apoptosis and inflammation of RA-FLSs (P＜0. 05) ．Dual luciferase reporting assay showed that miR-22-5p was a potential downstream miRNA target of MIR22HG． Conclusion MIR22HG is highly expressed in synovial tissues of RA patients，and it may promote the proliferation and the inflammatory response of RA-FLSs and inhibit cell apoptosis by down regulating the expression of miR-22-5p.

Objective To study the safety,efficacy and advantages of enhanced recovery after surgery (ERAS) combined with clinical pathway management in laparoscopic common bile duct exploration and lithotomy (Laparoscopic common bile duct exploration,LCBDE).Methods 78 patients who underwent LCBDE in the Department of Hepatobiliary and Pancreatic Surgery in the First Hospital of Fuyang District in Hangzhou were selected as the non-ERAS group (the control group).76 patients who underwent LCBDE treated with fast track surgery and ERAS clinical pathway management were selected as the ERAS group.The data between the two groups which included the postoperative insulin resistance index,changes in C-reactive protein,duration of postoperative analgesic use and analgesia,timing of first passage of postoperative flatus,postoperative abdominal tube removal,postoperative bile leakage,recurrence of biliary stones,intestinal ileus and other complications.Results All the two groups were discharged home successfully.On preoperative 7 day,the differences on the postoperative insulin resistance index and the levels of C reactive protein were significantly different (P＜0.05).The time to first get out of bed after operation,the postoperative analgesic use,the time to first passage of flatus,the time to postoperative abdominal drainage tube removal,and the time to clamping of the T tube after operation were significantly different (all P＜0.05).The postoperative complications of pulmonary infection,abdominal infection and the incidence of prolonged intestinal ileus were significantly different (all P＜0.05).Conclusions ERAS combined with clinical pathway management reduced postoperative stress reaction and complication rate.The treatment accelerated recovery and shortened hospital stay for patients who underwent LCBDE,which led to good social and economic benefits.

Objective To study the expressions of osteopontin (OPN),caspase-3 and mt-P53 proteins, and their relationship in gliomas. Methods Seventy gliomas specimens of patients (glioma group) were selected, and 10 samples of non-glioma brain tissue were used as control group. The SP method was used to detect the positive rates of protein expressions of OPN, caspase-3 and mt-P53 between two groups. The relationship between protein expressions of OPN, caspase-3 and mt-P53 in gliomas and grade of gliomas were detected by Western blot assay. Spearman rank correlation was compared between the positive expression of OPN, caspase-3 and rate mt-P53. Results The positive expression rates of OPN and mt-P53 were significantly higher in glioma group (64.29%and 60%) than those of control group (no positive expression), but the positive expression rate of caspase-3 was significantly lower than that of control group (47.14%vs. 90%, P<0.05). There were no significant differences in OPN, caspase-3 and mt-P53 expressions between different gender, age, tumor size and tumor position (P>0.05). The higher the WHO classification, the higher the positive expression rates of OPN and mt-P53 (P<0.001), and the lower the positive expression rate of caspase-3 (P<0.001). With the increased level of glioma grade, OPN and mt-P53 protein levels were increased, but caspase-3 protein expression level was decreased. There was a negatively correlation between OPN and the positive expression of caspase-3, but there was a positive correlation between OPN and the expression of mt-P53 (rs=-0.720 and 0.722, P<0.05). There was a negative correlation between caspase-3 and mt-P53 expressions (rs=-0.556, P<0.05). Conclusion The higher the WHO classification, the higher the positive expression rates of OPN and mt-P53, while the lower the positive expression rate of caspase-3. The study reveals that OPN, caspase-3 and mt-P53 expressions are associated with the occurrence and the progress of gliomas. The combined detection of them can contribute to the judgment of biological behavior of gliomas.
