Objective:To investigate the prevalence status and the clinical characteristics of hepatitis D virus (HDV) among patients chronically infected with hepatitis B virus (HBV) in the Xinjiang region.Methods:A cross-sectional study was conducted. Serum samples from 1 830 patients with chronic HBV infection who visited the Traditional Chinese Medicine Hospital of Xinjiang Uygur Autonomous Region from December 2022 to October 2023 were collected. All sera were tested for anti-HDV IgG and IgM. Sera positive for anti-HDV IgG or IgM were selected for HDV RNA detection. HDV RNA-positive sera were sequenced to determine the HDV genotype. Age, gender, HBV course, and anti-HBV treatment status were used as scoring items based on the propensity score matching (PSM) method. Chronic HBV patients with negative anti-HDV were matched in a ratio of 1∶1. The clinical characteristics of anti-HDV -positive-patients were analyzed. The t-test was used for comparison between groups of normally distributed continuous data. The Wilcoxon signed-rank test was used for comparison between groups of skewness distribution. The χ2 test was used for comparison between groups of enumeration data. Results:The positive detection rates of anti-HDV IgG, anti-HDV IgM, and HDV RNA in 1 830 cases with chronic HBV infection were 2.24% (41/1 830), 1.09% (20/1 830), and 1.69% (31/1 830), respectively. All HDV RNA-positive patients had HDV genotype 1. Two anti-HDV-positive patients had negative hepatitis B surface antigen (HBsAg). Gender, age, HBV course, and anti-HBV treatment status had no significant difference. The quantification of HBsAg, liver biochemical indexes (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and total bile acids), the proportion of patients with liver cirrhosis, and alpha-fetoprotein were significantly higher in the anti-HDV-positive group than in those in the anti-HDV-negative group ( P<0.05). Conclusion:The prevalence rate of HDV in chronic HBV-infected patients at a single center in the Xinjiang region was 2.24%, with the primary genotype being 1. Furthermore, overlap infection should be paid attention to because it might aggravate liver damage.

The sensitivity of cardiac troponin testing for diagnosing acute myocardial infarction(AMI)varies over time from chest pain onset.This study aimed to determine the diagnostic performance of point-of-care testing cardiac troponin T(POCT-cTnT)at different time intervals post-symptom onset to refine rapid rule-out approaches for AMI.Methods This retrospective study included 6,024 patients presenting with chest pain from January 2018 to December 2022.POCT-cTnT and central lab cTnI levels were measured on admission.Receiver operating charac-teristics analysis stratified by time windows assessed the accuracy of POCT-cTnT for diagnosing AMI.Results The overall AUC of POCT-cTnT for diagnosing AMI was 0.826(95%CI:0.816～0.836),with a sensitivity of 72.81%and a specificity of 86.26%.According to the time intervals of chest pain onset(＜3 hours,3～6 hours,6～12 hours,12～24 hours,24～72 hours,and≥72 hours),the AUC values for groups after 6～12 hours were 0.918,0.928,0.920 and 0.908,respectively,with no statistically significant difference(P＞0.05),but all were higher than the groups within 6 hours(P＜0.001).According to the time of chest pain onset,the AUC for the≥8h group was 0.921,with a negative predictive value(NPV)of 98.1%and a negative likelihood ratio(-LR)of 0.11.Its AUC was higher than those of the≥3 h,≥2 h,≥1 h,and overall groups(P＜0.05),but there was no statistically significant differ-ence compared with the groups after≥4 h(P＞0.05).Conclusions Chest pain onset time has a certain impact on the performance of a single POCT-cTnT test for diagnosing AMI.The duration from chest pain onset to hospital admission combined with POCT-cTnT test may improve the reliability in diagnosing AMI.Specifically,a single POCT-cTnT test at four hours after chest pain onset,especially eight hours after chest pain onset,can diagnose or exclude AMI.

Objective:To investigate the association between tumor necrosis factor-β (TNF-β) gene polymorphisms and genetic predisposition to gastric cancer, and to analyze the relationship between specific genotype of TNF-β and serum levels of TNF-β.Methods:Using case control study, we selected 153 patients with gastric cancer in Fudan University Shanghai Cancer Center between September 2021 and December 2022 as the gastric cancer group, and 150 healthy individuals were chosen as the healthy control group. In the previous study, 30 peripheral blood DNA samples of gastric cancer patients and healthy controls respectively were amplified by conventional PCR, which were sequenced to identify the genotype frequencies of TNF-β polymorphic loci (rs1041981, rs2229092, rs2229094 and rs78613290); consequently, Allele-Specific Quantitative PCR was used to further detect and analyze the genotype and genotype frequencies of TNF-β polymorphic loci; serum TNF-β levels were measured by Enzyme-Linked Immunosorbent Assay (ELISA), and the relationship with specific genotypes of TNF-β was analyzed. Chi-square test and Fisher test were used to analyze the genotype distribution frequency of TNF-β polymorphic loci, and non-parametric statistics was used to analyze the differences in serum TNF-β expression levels.Results:The sequencing results showed that the genotype distribution of rs1041981 in gastric cancer group was CC 16.67% (5/30), CA 40.00% (12/30) and AA 43.33% (13/30). The genotype distribution in control group was CC 40.0% (12/30), CA 43.33% (13/30), AA 16.7% (5/30). The difference of genotype frequency between the two groups was statistically significant (χ 2=6.478, P=0.039). The genotypes of the polymorphic loci rs2229092 in both groups were AA, AG, and GG, with no statistically significant difference between the two groups (χ 2=1.888, P=0.612). The distribution frequencies of the genotypes of the polymorphic loci rs2229094 (TT and TC) and rs78613290 (GG and AG) showed no statistically significant differences between the two groups (both P>0.05). Further validation with an expanded clinical samples (153 cases in the gastric cancer group and 150 cases in the control group) found that the difference of rs1041981 genotype distribution between the gastric cancer group [CC 15.69%(24/153), CA 54.9%(84/153), AA 29.4%(45/153)] and the control group [CC 27.3%(41/150), CA 58.0%(87/150), AA 14.7%(22/150)] was significantly different (χ 2=12.366, P=0.002). Analysis of the influence of different allele frequencies on the risk of gastric cancer revealed that the odds ratio ( OR) of the A allele of rs1041981 for the risk of gastric cancer compared to the C allele was 1.701 (95% CI 1.235?2.355). Gene phenotype analysis combining the clinicopathological characteristics of gastric cancer patients found that the distribution frequency of the rs1041981 genotype was significantly different among groups of different genders, tumor invasion depths, and the lymph node metastasis, with statistically significant differences (All P>0.05). Additionally, gastric cancer patients with rs1041981 AA genotypes had higher serum TNF-β expression levels than those with CA and CC genotypes, (both P<0.05). Conclusions:The gene type frequency of the TNF-β gene polymorphic loci (rs1041981, C>A) exhibited significant differences between the gastric cancer group and the healthy control group. The presence of the A allele in rs1041981 site increased the susceptibility to gastric cancer, and patients with different gene types displayed vaning levels of serum TNF-β, among which AA genotype ranks the highest level.

Objective:To explore the efficacy and safety profile of tenofovir alafenamide fumarate (TAF) in the treatment of patients with decompensated hepatitis B cirrhosis.Methods:A two-way cohort study method was used to enroll patients with decompensated hepatitis B cirrhosis who visited four medical centers, including Xinjiang Uygur Autonomous Region Hospital of Traditional Chinese Medicine, from April 2021 to April 2024 and were treated with TAF and followed up for 48 weeks. The primary efficacy indicator was hepatitis B virus (HBV) DNA seronegative conversion rate at 48-weeks, and the secondary efficacy indicator was alanine aminotransferase (ALT) return to normal rate at 48-weeks. Relevant safety indicators, adverse drug reactions (ADRs), and clinical adverse outcomes were collected.Results:A total of 74 cases were included. Of these, 52 were males with an average age of (53.14 ± 9.15) years. Twenty-five and thirty-three cases completed 24 and 48 weeks of follow-up, respectively. The HBV DNA negative conversion rate was 96.97% (32/33), which was higher than the baseline of 58.1% (43/74) following 48 weeks of TAF treatment. The ALT return to normal rate was 72.73% (24/33), which was higher than the baseline of 47.30% (35/74); however, the renal function and blood lipid levels did not change significantly compared with the baseline level after completing 48 weeks of treatment (P>0.05). During the follow-up period, one case developed hepatocellular carcinoma, and no other adverse clinical outcomes, such as liver transplantation or death, were reported.Conclusion:TAF has a good efficacy and safety profile in the treatment of patients with decompensated hepatitis B cirrhosis.

Objective:To investigate the clinical efficacy and safety of Pseudomonas aeruginosa injection in preventing reurrent urinary tract infection in women. Methods:This was a multicenter, randomized, open, positive-controlled, non-inferiority trial involving female patients with recurrent urinary tract infections (rUTIs) who were admitted to 11 medical centers in China. Inclusion criteria: ①Aged 18-70 years, with verifiable clinical data showing at least 3 episodes of acute UTIs within 1 year and at least 2 episodes within 6 months, and cured by antimicrobial therapy; ② At the time of enrollment, the patients had no obvious symptoms of urinary tract irritation, normal white blood cell count in midstream urine routine (within the normal range of laboratory standards of each unit) or ≤3HP by centrifuge microscopy, negative leucocyte esterase and nitrite, and negative urine culture; ③No abnormal urinary anatomic function (such as urinary obstruction, calculus or congenital urinary malformation) and residual urine volume ≤50 ml were detected by B-ultrasound of urinary system; ④Informed consent signed by the person or agent; ⑤Clear consciousness, able to answer questions independently, according to the requirements of the test plan to complete the research questionnaire. Exclusion criteria: ①Patients allergic to the above drugs; ②Any complex signs of urinary tract infection or pyelonephritis (manifested as low back pain, fever ≥37.3℃, systemic symptoms); ③Drugs affecting immune function were used within 7 days before randomization; ④Patients with basic diseases of urinary system such as obstruction, calculus, urinary stenosis, vesicoureteral reflux or other functional abnormalities, urine diversion, indwelling catheter or stent tube or intermittent catheterization; ⑤Combined with or existing systemic lupus erythematosus, AIDS and other diseases that can lead to systemic immune function abnormalities; ⑥Patients who are known or suspected to be pregnant, breastfeeding, or planning a pregnancy within 3 months of stopping the drug; ⑦Patients with malignant tumors and mental patients; ⑧Persons who have received any other investigational drug treatment or participated in another interventional clinical trial within 4 weeks prior to screening; ⑨Failure to comply with the trial protocol or other conditions deemed unsuitable for enrollment by the investigator. Patients were randomly divided into 2 groups. The experimental group was given Pseudomonas aeruginosa injection for 5 times, 0.5 ml for the first time, and 1 ml/ time per week for the following 4 weeks. The control group was given fosfomycin aminotriol 3g orally, once every 10 days, for 9 consecutive times. The patients were followed up for 6 to 8 months, during which urinary tract symptoms developed and routine urine tests showed abnormally elevated white blood cells, which was defined as recurrent UTIs. Urine routine, liver and kidney function, and urinary secretory immunoglobulin A(SIgA) were reviewed 0-2 days (V2) after the 5th administration of the experimental group and the 4th administration of the control group. Urine routine and urine SIgA were reviewed at (90±10) d (V3) and (180±10) d (V4) after treatment. At (270±10) d (V5) after treatment, the recurrence (re-infection caused by the same species of bacteria) or re-infection (re-infection caused by non-same species of bacteria) of the two groups were compared, and non-inferiority analysis was performed, and the non-inferiority threshold was set at 0.2. Results:From March 2021 to May 2022, a total of 152 rUTIs patients were enrolled in this study, including 80 patients in the experimental group, 71 patients in the intention-to-analysis set (ITT) and 66 patients in the protocol analysis set (PPS). In the control group, 72 cases met ITT in 69 cases and PPS in 67 cases. There were no significant differences in age, body mass index, marital status, duration of urinary tract infection, history of diabetes, history of previous major surgery, history of infection, and urinary SIgA between the two groups (all P>0.05). The recurrence rates of the experimental group and the control group at V5 time point were 44.78% (30/67) and 42.65% (29/68), respectively ( P=0.803) (ITT data set analysis results showed that the difference in recurrence rates between the two groups was 0.0213(95% CI-0.1460-0.1886, P=0.0048). PPS data set analysis showed that the difference of recurrence rate between the two groups was -0.0021(95%CI -0.1711-0.1670, P=0.0109), and the recurrence rate of the experimental group was not worse than that of the control group. At V2 time points, there were no significant differences in liver and kidney function indexes between test group and control group ( P>0.05). At V2 to V4 time points, urinary SIgA of test group and control group were 0.90 (0.37, 2.89) mg/L and 1.32 (0.34, 3.08) mg/L, 1.54 (0.44, 3.23) mg/L and 1.71 (0.27, 2.92) mg/L, 1.11 (0.65, 3.42) mg/L and 2.18 (0.43, 3.26) mg/L, there was no statistical significance ( P>0.05). The incidence of adverse events in the experimental group was 30.0% (24/80), including 14 cases of redness, pain and discomfort at the injection site, 5 cases of fever, 2 cases of allergic rash, and 1 case of urticaria, headache and constipation each. The incidence of adverse events in the control group was 5.6% (4/72), all of which were diarrhea, and the difference between the two groups was statistically significant ( P<0.01). No life-threatening serious adverse events occurred in both groups, and all adverse events were self-healing without additional intervention. Conclusions:Compared with fosfomycin aminotriol, Pseudomonas aeruginosa injection has the same clinical effect in preventing rUTI and has good safety.

The primary efficacy indicator was hepatitis B virus (HBV) DNA seronegative conversion rate at 48-weeks, and the secondary efficacy indicator was alanine aminotransferase (ALT) return to normal rate at 48-weeks. Relevant safety indicators, adverse drug reactions (ADRs), and clinical adverse outcomes were collected.Results:A total of 74 cases were included. Of these, 52 were males with an average age of (53.14 ± 9.15) years. Twenty-five and thirty-three cases completed 24 and 48 weeks of follow-up, respectively. The HBV DNA negative conversion rate was 96.97% (32/33), which was higher than the baseline of 58.1% (43/74) following 48 weeks of TAF treatment. The ALT return to normal rate was 72.73% (24/33), which was higher than the baseline of 47.30% (35/74); however, the renal function and blood lipid levels did not change significantly compared with the baseline level after completing 48 weeks of treatment (P>0.05). During the follow-up period, one case developed hepatocellular carcinoma, and no other adverse clinical outcomes, such as liver transplantation or death, were reported.Conclusion:TAF has a good efficacy and safety profile in the treatment of patients with decompensated hepatitis B cirrhosis.

There is currently a huge worldwide demand for donor kidneys for organ transplantation. Consequently, numerous marginal donor kidneys, such as kidneys with microthrombi, are used to save patients' lives. While some studies have shown an association between the presence of microthrombi in donor kidneys and an increased risk for delayed graft function (DGF) (McCall et al., 2003; Gao et al., 2019), other studies have demonstrated that microthrombi negatively impact the rate of DGF (Batra et al., 2016; Hansen et al., 2018), but not graft survival rate (McCall et al., 2003; Batra et al., 2016; Gao et al., 2019). In contrast, Hansen et al. (2018) concluded that fibrin thrombi were not only associated with reduced graft function six months post-transplantation but also with increased graft loss within the first year of transplantation. On the other hand, Batra et al. (2016) found no significant differences in the DGF rate or one-year graft function between recipients in diffuse and focal microthrombi groups. To date, however, the overall influence of donor kidney microthrombi and the degree of influence on prognosis remain controversial, necessitating further research.

Objective:To investigate the feasibility and accuracy of transperineal prostate targeted biopsy guided by holographic image.Methods:Clinical data of 10 patients with transperineal prostate targeted biopsy guided by holographic image in Peking University Shougang Hospital between May and September 2020 were analyzed retrospectively. The average age was (70.9±10.3) years old, the median PSA was 15.1(6.02-1110.14) ng/ml, prostate MRI were performed before biopsy and the PI-RADS scores were all ≥ 3, and the number of suspicious target lesions was 1.4±0.5. CT examinations of urinary system were performed on the premise of mild lithotomy position and positioning stickers pasted on the skin of perineum and lower abdomen. The original data of CT and MRI were obtained, holographic image models were firstly made separately and then fused into a complete model, and the puncture paths were planned for the target lesions. At the time of puncture, the patient took the same body position as in CT scan, the operator wore a mixed reality head mounted display (HoloLens glasses), and the skin positioning stickers were used for visual registration between the holographic model and the real human body. Then under the guidance of the virtual puncture path, the puncture biopsy gun was placed, fired after reaching the predetermined depth, a transrectal ultrasound probe was placed to clarify the position of the puncture needle, and the objective accuracy of puncture was judged by comparison of ultrasound and MRI images. If the first shot was judged to be inaccurate, it was allowed to make a supplementary shot after adjusting the angle. After holographic guided biopsies, cognitive fusion targeted biopsies and 12-needle systematic biopsies were performed routinely, and the proportion of positive needles of the three different biopsy methods were calculated respectively.Results:All the 10 cases were successfully completed, including 16 holographic image guided shots, 28 cognitive fusion targeted shots and 116 systematic shots. The objective accuracy of holographic image guided biopsy after first shot judgments was 68.8% (11/16), while it raised to 87.5% (14/16) after supplementary shots. The proportion of positive needles in the three puncture methods were 56.3% (9/16), 42.9% (12/28) and 19.8% (23/116), respectively ( P=0.002). The results of subjective questionnaire showed that holographic model was helpful to improve the spatial understanding of lesions. The satisfaction of intraoperative holographic registration and guided puncture were 90% and 60%, respectively. No puncture related complication occurred in this group. Conclusion:The study preliminarily confirmed the feasibility of holographic image-guided prostate targeted biopsy. This new puncture method has better objective accuracy, and the proportion of positive needles is significantly better than systematic biopsy.
