Background Personal protection is crucial for reducing the risk of zoonotic pathogen infection among livestock workers. Investigating the current status of its implementation and associated influencing factors can provide empirical evidence for developing more effective intervention measures. Objective To investigate the current status of personal protection implementation among livestock workers in Xinjiang, China and its influencing factors, providing a reference for formulating targeted intervention measures. Methods This study was conducted in Bayingolin Mongol Autonomous Prefecture, Kashgar region, and the First and Eighth Divisions of Xinjiang Production and Construction Corps. We selected large-scale cattle and sheep farms, cooperatives, individual livestock households, livestock trading markets, slaughterhouses, and retail markets. Using cluster sampling, we recruited all livestock workers (1074 participants) at sampled sites. During the period from April to July 2024, we conducted face-to-face surveys with a self-designed questionnaire among livestock workers, collecting general demographic information, occupational exposure history, and information related to the use of personal protective equipment, resulting in 939 valid questionnaires. EpiData 3.1 was used for data entry and SPSS 26.0 for statistical analysis. We employed logistic regression to compare the implementation of personal protection among workers by selected categories. Results Among the study subjects, there were 300 workers from large-scale farms (31.95%) and 583 self-employed livestock farmers (62.09%). The sample included 600 males (63.90%) and 339 females (36.10%). The majority of the study subjects was farmers, breeders, or aged 18-60 years (87.75%), auxiliary workers (87.97%) and had an education level of junior high school or below (81.36%). The proportion of workers who consistently and correctly implemented all five personal protective measures (washing hands after work, wearing gloves, wearing masks, wearing dedicated work clothes, and using rubber boots) was 35.14% (330/939). The implementation rates for these five protective measures were 93.61% (879/939), 58.68% (551/939), 57.93% (544/939), 46.01% (432/939), and 42.81% (402/939), respectively. There were statistically significant differences in the implementation rates of differen personal protective measures among the workers by occupation and education level (P<0.05). Among them, workers with lower education levels had lower implementation rates for various protective measures. The results of logistic regression indicated that, compared to male workers, female workers (OR=2.26, 95%CI: 1.68, 3.04) showed a higher rate of non-standard implementation of personal protection. Using the age group of 18 to less than 36 years as a reference, those aged 36 to less than 60 years (OR=1.82, 95%CI: 1.33, 2.50) and 60 years or older (OR=4.45, 95%CI: 2.56, 7.73) reported higher rates of non-standard implementation of personal protection. Compared to those with an education level of primary school or below, those with a junior high school education (OR=0.64, 95%CI: 0.47, 0.88) and a high school education or above (OR=0.13, 95%CI: 0.19, 0.29) showed lower rates of non-standard implementation of personal protection. Compared to farmers, veterinarians (OR=0.03, 95%CI: 0.02, 0.07) reported the lowest rate of non-standard implementation of personal protection, followed by auxiliary workers (OR=0.08, 95%CI: 0.05, 0.12), breeders (OR=0.10, 95%CI: 0.07, 0.15), and other occupational groups (OR=0.28, 95%CI: 0.15, 0.52). Using large-scale farms as a reference, self-employed farmers (OR=13.5, 95%CI: 9.65, 18.88) reported a higher rate of non-standard implementation of personal protection, followed by workers from other workplaces (OR=3.63, 95%CI: 2.01, 6.54). Conclusion The implementation of personal protective measures among livestock workers in Xinjiang is generally satisfactory. However, significant disparities in the execution of these measures exist among different types of workers, indicating the need to enhance occupational health promotion to reduce the risk of zoonotic pathogen infection among the workers.

Background Animal farming may affect the structure and diversity of gut microbiota of farm workers, but it needs more studies to provide solid evidence. Objective To analyze the diversity characteristics of gut microbiota in dairy farm workers, dairy cows, and the control population (non-animal contact occupational group), and to assess the impact of dairy farming on the gut microbiota of workers. Methods The 16S rRNA full-length amplicon sequencing technology was used to sequence 60 fecal samples from dairy farm workers, 89 from dairy cows, and 50 from the general population. The gut microbiota structure characteristics, including operational taxonomic units (OTUs), alpha diversity, beta diversity, and the composition of species at the phylum, family, and genus levels were analyzed. The differences in gut microbiota among the three groups of samples were compared to explore the impact of occupational exposure on the gut microbiota structure of dairy farm workers. Results A total of 50478 OTUs were identified in the gut microbiota of farm workers, dairy cows, and the general population, with 23613, 42723, and 16592 OTUs, respectively. The number of shared OTUs between the dairy cows and the general population was 12674 (27.17%), between the general population and the farm workers was 10099 (33.54%), and between the dairy cows and the farm workers was 17690 (36.36%). Compared with the general population, the farm workers and dairy cows showed more shared gut microbiota (P<0.01). The abundance of Firmicutes in the gut of the farm workers was higher than that of the general population (P<0.01), while Actinobacteriota and Proteobacteria were the opposite (P<0.01). The alpha diversity of gut microbiota in the farm workers was different from that of the general population. The ACE index of the farm workers was slightly lower than that of the general population and much lower than that of dairy cows (P<0.05), while their Shannon index was higher than that of the general population but lower than that of dairy cows (P<0.01). The linear discriminant analysis effect size (LefSe) showed that the abundances of Lachnospiraceae and Ruminococcaceae in the gut microbiota of the farm workers were significantly higher than those of the general population, while Streptococcaceae, Lactobacillaceae, Bifidobacteriaceae, Enterobacteriaceae, and Erysipelatoclostridiaceae were lower than those of the general population. Conclusion The dairy farm workers shares a certain proportion of common bacterial communities with dairy cows. Dairy farming operations can affect the structure and diversity of the gut microbiota of workers by increasing the abundances of Lachnospiraceae and Ruminococcaceae, while decreasing the abundances of Streptococcaceae, Lactobacillaceae, Bifidobacteriaceae, Enterobacteriaceae, and Erysipelatoclostridiaceae. The study results provide reference data for further exploring the cross-host transmission of pathogens related to occupational exposure in dairy farming.

BACKGROUND:With the increase of patients with cubital tunnel syndrome,ulnar groove plasty does not affect the normal anatomical structure and distribution of the ulnar nerve,which is one of the main surgical procedures for the treatment of cubital tunnel syndrome.3D printing combined with ulnar groove plasty can more accurately position the expansion depth and width of the ulnar groove to avoid some surgical complications. OBJECTIVE:To investigate the effect of 3D printing technology combined with ulnar groove plasty on nerve electrophysiology and prognosis in patients with cubital tunnel syndrome. METHODS:A total of 70 patients with moderate and severe cubital tunnel syndrome who were treated in Cangzhou Integrated Traditional Chinese and Western Medicine Hospital from March 2020 to March 2022 were selected as the study subjects.They were divided into two groups,with 35 cases in each group.The control group underwent traditional ulnar groove plasty.The observation group underwent 3D printing technology combined with ulnar groove plasty.The patients were followed up for 3 months.The clinical efficacy,latency,amplitude of compound muscle action potential of abductor pollicis brevis of the affected limb and ulnar nerve motor conduction velocity,grip strength on the affected side,pinch strength of the middle and thumb fingers,S-W monofilament of the little finger,two-point discrimination of the little finger,and Disabilities of the Arm,Shoulder and Hand Questionnaire score were compared between the two groups. RESULTS AND CONCLUSION:(1)Compared with the control group(74%),the excellent and good rate was significantly higher in the observation group(91%)(P<0.05).(2)Compared with pre-treatment,the latency of compound muscle action potential of abductor pollicis brevis of affected limb was significantly shorter and the wave amplitude and ulnar nerve motor conduction velocity were significantly higher in the two groups after treatment.The latency was significantly shorter and the wave amplitude and ulnar nerve motor conduction velocity were significantly higher in the observation group than those in the control group(P<0.05).(3)Compared with pre-treatment,the grip strength,middle finger and thumb pinch strength of the affected side,S-W monofilament of the little finger and two-point discrimination of the little finger were significantly decreased in the two groups after treatment.The grip strength,middle finger and thumb pinch strength on the affected side were greater,S-W monofilament of the little finger and two-point discrimination of the little finger were significantly smaller in the observation group than those in the control group(P<0.05).(4)Compared with pre-treatment,the Disabilities of the Arm,Shoulder and Hand Questionnaire scores of the two groups were significantly reduced after treatment,and the Disabilities of the Arm,Shoulder and Hand Questionnaire scores of the observation group were significantly lower than those of the control group(P<0.05).(5)It is concluded that 3D printing technology combined with ulnar groove plasty in the treatment of cubital tunnel syndrome can effectively improve its clinical efficacy,promote the neurophysiological recovery of patients,and enhance the function of fingers and upper limbs,which has high clinical application value.

Objective:To assess the efficacy, safety, and related prognostic factors associated with the P-GemDOx regimen as a first-line treatment for patients with early-stage extranodal natural killer (NK) /T cell lymphoma (ENKTL) .Methods:A retrospective analysis was performed on sixty early-stage ENKTL patients treated with the P-GemDOx regimen who were admitted to the First Affiliated Hospital of Nanjing Medical University between August 2015 and May 2021. The Chi-square test or Fisher's exact test was used to compare group differences, and the Log-rank test was used to compare the differences in survival. Survival outcomes and prognostic factors were examined.Results:After completing 4 to 6 cycles of P-GemDOx chemotherapy, the overall response rate (ORR) was 88.3%, with forty-six patients (76.7% ) achieving complete response (CR). The 4-year progression-free survival (PFS) and overall survival (OS) rates were (66.3±7.1) % and (79.5±6.0) %, respectively. According to the PINK/PINK-E model, there was no significant difference in survival outcomes among risk groups. 23.3% of patients experienced progression of disease within 24 months (POD<24). OS estimates differed significantly ( P<0.001) between the POD<24 group ( n=14) and the POD≥24 group ( n=46). Analysis showed that SUVmax > 12.8 at diagnosis, non-single nasal cavity infiltration, and response less than CR after 4–6 cycles all had a significant association with POD24. We used these data as the basis for predicting POD<24 international prognostic index (POD24-IPI). Patients were stratified into low-risk (no risk factors), intermediate-risk (one risk factor), or high risk (two or three risk factors). These groups were associated with 4-year OS rate of 100%, (85.6±9.7) %, and (65.0±10.2) %, respectively ( P=0.014). The P-GemDOx regimen was well tolerated, with hematological toxicity being the main side effect. Conclusion:This study demonstrated that the P-GemDOx regimen is effective and safe in the first-line treatment of early-stage ENKTL, and POD24-IPI is a promising prognostic model.

Objective:To analyze the sensitivity of cytoplasmic light-chain immunofluorescence with fluorescence in situ hybridization in bone marrow smears (new FISH) for detecting cytogenetic abnormalities in multiple myeloma (MM) .Methods:42 MM patients admitted to the First Affiliated Hospital of Nanjing Medical University from April 2022 to October 2023 were enrolled. The patients with MM were detected by new FISH and CD138 immunomagnetic bead sorting technology combined with FISH (MACS-FISH) or cytoplasmic immunoglobulin FISH (cIg-FISH) to analyze cytogenetic detection results using combination probes which included 1q21/1p32, p53, IgH, IgH/FGFR3 [t (4;14) ], and IgH/MAF [t (14;16) ].Results:In 23 patients with MM, the abnormality detection rates of cIg-FISH and new FISH were 95.7% and 100.0%, respectively ( P>0.05). The detection rates of 1q21+, 1p32-, p53 deletion, and IgH abnormalities by cIg-FISH and new FISH were consistent, which were 52.2%, 8.7%, 17.4%, and 65.2%, respectively. The results of the two methods further performed with t (4;14) and t (14;16) in patients with IgH abnormalities were identical. The positive rate of t (4;14) was 26.7%, whereas t (14;16) was not detected. In 19 patients with MM, the abnormality detection rates of MACS-FISH and new FISH were 73.7% and 63.2%, respectively ( P>0.05). The positivity rate of 1q21+, 1p32- and IgH abnormalities detected by MACS-FISH were slightly higher than those detected by new FISH; however, the differences were not statistically significant (all P values >0.05) . Conclusion:The new FISH method has a higher detection rate of cytogenetic abnormalities in patients with MM and has good consistency with MACS-FISH and cIg-FISH.

Objective:To investigate the efficacy and safety of orelabrutinib combined with R-CHOP in the treatment of MCD subtype diffuse large B cell lymphoma (DLBCL) .Methods:Twenty-three MCD subtype patients whose gene-subtype classification was based on baseline tumor tissue and/or baseline plasma using the LymphGen algorithm from June 2022 to June 2023 in the First Affiliated Hospital of Nanjing Medical University were retrospectively enrolled in the analysis. All patients were treated with R-CHOP or R-miniCHOP in Course 1, OR-CHOP or OR-miniCHOP (21 days for one course) in Courses 2-6, and R-monotherapy in Courses 7-8.Results:Of the 23 patients, the median age was 58 years (range: 30-81 years), and 11 (47.8% ) aged >60 years. Fifteen cases (65.2% ) had international prognostic index (IPI) scores of 3 to 5. The top 10 mutated genes in the gDNA tissues were PIM1 (78.3% ), MYD88 (69.6% ), ETV6 (43.5% ), BTG1 (39.1% ), CD79B (43.5% ), HIST1H1E (39.1% ), BTG2 (34.8% ), KMT2D (30.4% ), CD58 (26.1% ), and CDKN2B (21.7% ). The consistency rate of the tissue and plasma mutations was 80%, while the baseline plasma ctDNA burden was closely correlated with the LDH levels and IPI scores ( P<0.05). All patients received 5 courses of OR-CHOP regimens. The mid-term (after 3 courses) evaluation showed that the overall response rate (ORR) was 100% (23/23), with 22 patients (95.65% ) achieving complete remission (CR), and 1 patient (4.35% ) achieving partial remission (PR). The ORR after the end of treatment (EOT) was 95.65% (22/23). Moreover, 21 patients (91.30% ) obtained CR, 1 patient (4.35% ) obtained PR, and 1 patient (4.35% ) obtained progression disease (PD). Of the 21 patients who had the dynamic EOT-ctDNA burden, only four patients (19.0% ) did not achieve EOT-ctDNA clearance, while the other 17 patients (81.0% ) achieved EOT-ctDNA clearance. The median follow-up time was 20.8 (15.3-30.0) months, while the median progression-free survival (PFS) and overall survival (OS) were not reached. The 2-year PFS rate was 71.8% (95% CI 54.7% -94.2% ), while the 2-year OS rate was 91.3% (95% CI 80.5% -100.0% ). Furthermore, the OR-CHOP regimen was generally well tolerated during clinical use, with hematological toxicity being the main adverse effect. Conclusion:This study revealed that the OR-CHOP regimen can be used as an effective and safe first-line treatment for MCD subtype DLBCL.

Background:Following the short-term outbreak of coronavirus disease 2019(COVID-19)in December 2022 in China,clinical data on kidney transplant recipients(KTRs)with COVID-19 are lacking.Methods:We conducted a single-center retrospective study to describe the clinical features,complications,and mortality rates of hospitalized KTRs infected with COVID-19 between Dec.16,2022 and Jan.31,2023.The patients were followed up until Mar.31,2023.Results:A total of 324 KTRs with COVID-19 were included.The median age was 49 years.The median time between the onset of symptoms and admission was 13 d.Molnupiravir,azvudine,and nirmatrelvir/ritonavir were administered to 67(20.7%),11(3.4%),and 148(45.7%)patients,respectively.Twenty-nine(9.0%)patients were treated with more than one antiviral agent.Forty-eight(14.8%)patients were treated with tocilizumab and 53(16.4%)patients received baricitinib therapy.The acute kidney injury(AKI)occurred in 81(25.0%)patients and 39(12.0%)patients were admitted to intensive care units.Fungal infections were observed in 55(17.0%)patients.Fifty(15.4%)patients lost their graft.The 28-d mortality rate of patients was 9.0%and 42(13.0%)patients died by the end of follow-up.Multivariate Cox regression analysis identified that cerebrovascular disease,AKI incidence,interleukin(IL)-6 level of>6.8 pg/mL,daily dose of corticosteroids of>50 mg,and fungal infection were all associated with an increased risk of death for hospitalized patients.Conclusions:Our findings demonstrate that hospitalized KTRs with COVID-19 are at high risk of mortality.The administration of immunomodulators or the late application of antiviral drugs does not improve patient survival,while higher doses of corticosteroids may increase the death risk.

Objective:To investigate the predictive value of preoperative γ-glutamyl transferase/lymphocyte count ratio (GLR) levels for postoperative tumor recurrence in liver transplant recipients with liver cancer.Methods:The clinical data of 158 recipients who were diagnosed with hepatocellular carcinoma (hereinafter referred to as liver cancer) and received liver transplantation at the No. 900 Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from January 2008 to October 2022 were retrospectively analyzed. X-tile software, the Kaplan-Meier method, univariate and multivariate Cox regression, and other statistical methods were performed. The predictive value of preoperative GLR levels for postoperative tumor recurrence in liver transplant recipients with liver cancer and the risk factors for tumor recurrence in liver cancer patients post-liver transplantation were analyzed.Results:The X-tile software analysis confirmed that 96.8 was the optimal cutoff value for the preoperative GLR level to predict recurrence. The grouping threshold for survival analysis using the GLR cutoff value was 96.8. The tumor recurrence rates at 1, 3, and 5 years after surgery in the low-level GLR group (90 cases) and the high-level GLR group were 19.3% vs. 44.2%, 31.8% vs. 60.0%, and 34.1% vs. 62.9% (68 cases), respectively, and the differences were statistically significant between the two groups ( P<0.05). The Kaplan-Meier survival curve analysis results showed that the overall postoperative survival rate and recurrence-free survival rate were significantly lower in the high-level GLR group than the low-level GLR group ( P<0.05). The univariate Cox analysis result showed that there were statistically significant differences in preoperative aspartate aminotransferase, alpha fetoprotein, surgery time, maximum diameter of a solitary tumor, presence or absence of microvascular invasion, presence or absence of portal vein tumor thrombus, and preoperative GLR levels between the two groups ( P<0.05). Multivariate Cox analysis results showed that preoperative alpha-fetoprotein ≥400 ng/ml, GLR≥96.8, and the maximum diameter of a solitary tumor ≥5.0 cm were independent risk factors for postoperative tumor recurrence in liver transplant recipients with liver cancer ( P<0.05). Conclusion:GLR levels have a certain predictive value for postoperative tumor recurrence in liver transplant recipients with liver cancer. Furthermore, the postoperative tumor recurrence rate is relatively high when the preoperative GLR level in liver transplant recipients with liver cancer is ≥96.8.

Chronic lymphocytic leukemia (CLL) is a hematologic malignancy characterized by clonal proliferation of lymphocytes. To meet the demands of energy, tumor cells can drive metabolic reprogramming. Previous studies have shown that the transformation of metabolic patterns in CLL cells is closely related to disease progression, treatment and prognosis. This article reviews the role of metabolic reprogramming in CLL in order to help in-depth understanding of the metabolic heterogeneity of CLL cells, and provide ideas for finding feasible therapeutic targets involved in the metabolic process of CLL.

Objective:To explore the influencing factors of acute rejection (AR) within one year after pediatric kidney transplantation (KT) and the effect of AR onset time on prognosis.Methods:From January 2011 to October 2021, a total of 112 patients aged under 18 years at the time of transplantation were selected.After excluding 6 of them with early renal non-function caused by non-rejection, 106 cases were examined.There were 63 males and 43 females with the age of 15(12, 16) years.The donors were living related (n=26) and deceased (n=80).According to the presence/absence and onset time of AR, they were assigned into three groups of AR within one year, AR after one year and non-AR.The relevant clinical data of donor/recipient, influencing factors of AR and therapeutic outcomes of AR were retrospectively compared.One-way ANOVA or Kruskal-Wallis test was utilized for comparing 1-year renal function after the occurrence of AR among three groups.With graft-function loss as an end-point event of follow-up, the effects of AR within one year and AR after one year on survival rate and function of graft-kidney were analyzed by Kaplan-Meier survival curve.Results:The median follow-up period of 106 pediatric KT recipients was 35 months.During follow-ups, 19 episodes of AR occurred in 17(16.0%) patients and 89 recipients exhibited no AR episode by the end of follow-up (non-AR group).As for initial AR, 9 episodes of AR occurred within one year (AR within one year group) and 8 episodes of AR after one year (AR after one year group).After anti-rejection treatment, 8 patients (47.1%) achieved full recovery and 6 patients (35.3%) failed to completely normalize and 3 patients (17.6%) developed graft failure.Univariate analysis indicated that, as compared with non-AR group, female recipients, donors aged under 8 years and early postoperative infection with parvovirus B19 were risk factors of AR within one year ( P=0.032, P=0.039, P=0.047).Kaplan-Meier survival analysis revealed that the incidence rates of AR within one year in patients with donors aged under 8 years and early postoperative parvoviral infection were 14.5%(8/55) and 30.0%(3/10) respectively.They were significantly higher than 2.0%(1/51) and 6.3%(6/96) of patients with donors aged above 8 years and those without parvoviral infection ( P=0.012, P=0.004).With graft-function loss as an end-point event of follow-up, Kaplan-Meier survival analysis showed that 10-year kidney graft survival rate in AR within one year and AR after one year groups were 88.9% and 65.6%.Both were significantly lower than that in non-AR group (98.9%).And the inter-group differences were statistically significant ( χ2=4.286, P=0.038; χ2=7.787, P=0.005).However, no significant difference existed in survival rate between AR within one year and AR after one year groups ( P=0.689).One-way ANOVA and Kruskal-Wallis test indicated that estimated glomerular filtration rates at 3/6/12 months after an onset of AR in AR within one year group were (76.8±51.6), (80.6±56.6) and (85.6±40.2) ml·min -1·1.73 m -2.The values of 3/6 months were lower than (125.3±39.2) and (124.7±38.2) ml·min -1·1.73 m -2 in AR after one year group.And the inter-group differences were statistically significant ( P=0.021, P=0.039).The values of 3/6/12 months were lower than (112.2±34.2), (115.3±33.2) and (117.4±30.2) ml·min -1·1.73 m -2 in non-AR group.And the inter-group differences were also statistically significant ( P=0.019, P=0.020, P=0.020). Conclusions:Female recipients, donors aged under 8 years and early postoperative infection with parvovirus B19 may elevate the risks of AR in children within one year of KT.AR within one year affects the survival rate of graft-kidney and renal function.
