OBJECTIVE: To explore the relationship between serum chloride levels and prognosis in patients with hepatic coma in the intensive care unit (ICU). METHODS: We analyzed 545 patients with hepatic coma in the ICU from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Associations between serum chloride levels and 28-day and 1-year mortality rates were assessed using restricted cubic splines (RCSs), Kaplan-Meier (KM) curves, and Cox regression. Subgroup analyses, external validation, and mechanistic studies were also performed. RESULTS: A total of 545 patients were included in the study. RCS analysis revealed a U-shaped association between serum chloride levels and mortality in patients with hepatic coma. The KM curves indicated lower survival rates among patients with low chloride levels (< 103 mmol/L). Low chloride levels were independently linked to increased 28-day and 1-year all-cause mortality rates. In the multivariate models, the hazard ratio ( HR) for 28-day mortality in the low-chloride group was 1.424 (95% confidence interval [ CI]: 1.041-1.949), while the adjusted hazard ratio for 1-year mortality was 1.313 (95% CI: 1.026-1.679). Subgroup analyses and external validation supported these findings. Cytological experiments suggested that low chloride levels may activate the phosphorylation of the NF-κB signaling pathway, promote the expression of pro-inflammatory cytokines, and reduce neuronal cell viability. CONCLUSION Low serum chloride levels are independently associated with increased mortality in patients with hepatic coma.

Objective To systematically evaluate the effects of total intravenous anesthesia and inhalational anesthesia on postoperative recovery in patients undergoing transsphenoidal pituitary tumor resection.Methods A comprehensive search was conducted in international biomedical databases including Ovid Medline,Embase,CINAHL(EBSCO),Cochrane Library,and Web of Science,from inception to July 4,2023.Additionally,ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing and completed trials.The randomized controlled trials(RCT)comparing total intravenous anesthesia and inhalational anesthesia in patients undergoing transsphenoidal surgery for pituitary tumors were included.The methodological quality of the included studies was evaluated by the Cochrane Collaboration tool.Relevant data were extracted and synthesized for analysis.Results A total of 327 records were identified,of which eight RCTs met the inclusion criteria.Four studies showed that the patients receiving desflurane or sevoflurane anesthesia experienced faster emergence from anesthesia than those receiving propofol.Two studies indicated that patients in the propofol group had lower levels of emergence agitation and a lower incidence of early postoperative nausea and vomiting.The results on postoperative cognitive function were inconsistent across studies.No differences were found between the groups in terms of postoperative complications or overall recovery quality during hospitalization.Conclusions Inhalational anesthesia appears to provide an advantage in promoting faster emergence following transsphenoidal pituitary surgery,whereas total intravenous anesthesia may contribute to smoother and more stable recovery.Further high-quality studies are needed to clarify the effects of different anesthetic techniques on both short- and long-term postoperative recovery.

Objective:To investigate the relationship among seminal oxidation-reduction potential(nORP),sperm DNA frag-mentation(DFI)and semen parameters in patients with varicocele.Methods:Clinical data of 522 patients treated in the reproduc-tive andrology clinic of the Northern Theater General Hospital from November 2023 to December 2023 were retrospectively analyzed,in-cluding 435 men of childbearing age and 87 men of infertile age.The patients were divided into the varicocele group(n=116)and non-varicocele group(n=406)according to clinical diagnosis.The differences of seminal plasma nORP,DFI,sperm high DNA stain ability(HDS)and semen parameters were analyzed between the two groups.The relationship among general clinical data,seminal plasma nORP,semen parameters,DFI and HDS in patients with varicocele were further analyzed.According to the severity of varico-cele,the patients were divided into three groups,including mild,moderate and severe.And the differences of seminal plasma nORP and semen parameters,DFI and HDS among all groups were analyzed.The differences of seminal plasma nORP,semen parameters,DFI and HDS were compared between the varicocele and non-varicocele groups.Results:The total sperm count,sperm concentra-tion,progressive motility sperm percentage(PR％)and normal sperm morphology rate(NSMR)in patients with varicocele were sig-nificantly lower than those in control group(P＜0.05).And seminal plasma nORP,DFI and HDS in patients with varicocele were sig-nificantly higher than those in control group(P＜0.05).Seminal plasma nORP in patients with varicocele was significantly negatively correlated with total sperm,sperm concentration and NSMR(P＜0.05),and significantly positively correlated with DFI and HDS(P＜0.05).There were significant differences in nORP,total sperm count,sperm concentration,PR％,DFI and HDS among mild,moderate and severe varicocele groups(P＜0.05).Seminal plasma nORP,sperm concentration,PR％and DFI in severe group were significantly lower than those in mild and moderate groups(P＜0.05).Sperm count and HDS in severe group were significantly lower than those in mild group(P＜0.05).In infertile patients,seminal plasma nORP,DFI and HDS in varicocele group were significantly higher than those in control group(P＜0.05).And PR％in varicocele group was significantly lower than that in control group(P＜0.05).Conclusions:Seminal plasma nORP in patients with varicocele may be an important marker of oxidative stress affecting DFI and semen parameters.

Objective:To investigate the impact of vitamin D deficiency on the outcomes of in vitro fertilization and embryo transfer (IVF-ET) in women with polycystic ovary syndrome (PCOS) and normal ovarian reserve (NOR). Methods:A retrospective cohort study was conducted on infertile women undergoing their first IVF-ET cycle in the Department of Reproductive Genetics, Zhengzhou Maternity and Child Health Care Hospital from January 2018 to December 2023, including 318 PCOS patients (group P) and 528 NOR patients (group N). Each group was divided into three subgroups according to serum 25-hydroxyvitamin D [25(OH)D] levels: severe deficiency [25(OH)D<12 μg/L], deficiency [12 μg/L≤25(OH)D<20 μg/L], and non-deficiency [25(OH)D≥20 μg/L]. The impact of vitamin D deficiency on pregnancy outcomes was analyzed in each group. 1∶1 propensity score matching was applied to match the baseline characteristics between group P and group N , resulting in 158 matched cases of PCOS (group P) and NOR (group N). Pregnancy outcomes were compared between the two groups under the same vitamin D status.Results:1) Among PCOS patients, there were no significant differences in general characteristics and pregnancy outcomes among the three subgroups (all P>0.05). The two pronuclei (2PN) rate in the severe deficiency subgroup [59.93% (721/1 203)] was significantly lower than that in the deficiency subgroup [63.70% (1 032/1 620)], with a statistically significant difference ( P=0.045), and both were lower than that in the non-deficiency subgroup [68.06% (554/814)], with a statistically significant difference ( P<0.001, P=0.037). There were no statistically significant differences in the number of oocytes retrieved and MⅡ oocytes, MⅡ oocyte rate, 2PN number, 2PN rate, cleavage number, cleavage rate, number of available embryos on day 3 (day 3, D3), number of high-quality embryos on D3, D3 high-quality embryo rate, clinical pregnancy rate, embryo implantation rate, early miscarriage rate, live birth rate, and premature birth rate among subgroups (all P>0.05). Female age ( OR=0.930, 95% CI: 0.871-0.992, P=0.028), endometrial thickness on the day of transfer ( OR=0.877, 95% CI: 0.791-0.971, P=0.012), number of D3 high-quality embryos ( OR=1.135, 95% CI: 1.050-1.228, P=0.001), and ovulation stimulating protocol ( OR=2.230, 95% CI: 1.153-4.314, P=0.017) were independent factors influencing clinical pregnancy. 2) Among NOR patients, there were no significant differences in general characteristics, pregnancy outcomes, laboratory parameters, or other outcome-related indices among the three subgroups (all P>0.05). Female age ( OR=0.944, 95% CI: 0.900-0.990, P=0.018), number of D3 high-quality embryos ( OR=1.070, 95% CI: 1.004-2.597, P=0.037), and number of transferred embryos ( OR=1.753, 95% CI: 1.184-2.597, P=0.005) were independent factors influencing clinical pregnancy. 3) After matching, there were no significant differences in baseline characteristics and pregnancy outcomes between group P and group N (all P>0.05). In the severe vitamin D deficiency state, group P had significantly lower MⅡ oocyte rate [76.64% (525/685)], 2PN rate [59.69% (345/578)], embryo implantation rate [35.71% (30/84)], and live birth rate [34.00% (17/50)] compared with group N [81.58% (465/570), P=0.033; 67.00% (335/500), P=0.013; 51.28% (40/78), P=0.046; 55.32% (26/47), P=0.035]. In the vitamin D deficiency state, the 2PN rate in group P [66.50% (532/800)] was significantly lower than that in group N [72.00% (725/1 007), P=0.012]. Conclusion:Vitamin D deficiency may adversely affect IVF-ET outcomes in patients with PCOS, with more pronounced effects in cases of severe deficiency. However, it has no impact on the assisted reproductive outcomes in NOR patients.

Objective:To explore the clinical characteristics and prognosis risk factors of aggressive NK-cell leukemia(ANKL).Methods:The clinical and laboratory data of 34 patients with ANKL and 15 patients with chronic lymphoproliferative disorders of NK cells(CLPD-NK)admitted to the First Affiliated Hospital of Zhengzhou University from September 2019 to December 2024 were retrospectively analyzed.The Kaplan-Meier method was used to calculate survival rates,and the Cox proportional hazards regression model was used to analyze prognostic factors.Results:Compared with CLPD-NK patients,ANKL patients had a younger median age of onset,a higher proportion patients with EBV-DNA≥500 copies/ml,hepatosplenomegaly and hemophagocytic syndrome.They also presented with a higher peak of fever,a shorter median survival time,lower WBC count,PLT count,ALB and Fib values,while having higher LDH,AST,TG,ferritin,CRP and PCT levels.There were statistically significant differences in the morphology and expression of HLA-DR,CD56,CD57,CD16 and CD158 on abnormall cells between ANKL patients and CLPD-NK patients.Multivariate survival analysis revealed that combined with asparaginase treatment could improve patients' survival,and CRP≥ 15 mg/L and Fib＜2.0 g/L were independent risk factors affecting the overall survival of patients with ANKL.Conclusion:The differences in clinical features and laboratory tests between patients with ANKL and CLPD-NK aid in the diagnosis of ANKL.CRP and Fib levels can be used to predict the prognosis of patients,and combined asparaginase therapy can enhance the overall survival of patients.

Aim To investigate the protective effects of Tilianin on lipopolysaccharide(LPS)-induced septice-mia-induced myocardial injury in rats and to explore the related mechanisms.Methods Animals were ran-domly grouped and a rat septicemia-induced myocardial injury model was constructed.Echocardiography was used to assess the cardiac function of rats,left ventricu-lar internal diameter at end-diastole(LVIDd)and left ventricular internal diameter at end-systole(LVIDs)were measured,and left ventricular ejection fraction(LVEF)and left ventricular fractional shortening(LVFS)were calculated;the kits were used to detect the serum activity of the relevant cardiac enzymes and the level of inflammatory factors;HE staining was used to observe the morphological changes of myocardium;immunofluorescence staining of cardiac tissues was used to detect the nuclear translocation of NF-κB p65;Western blot was used to detect the expression of TLR4,MyD88,p-NF-κB p65,and NLRP3 proteins in cardiac tissues.Results Compared with the model group,each administration group differently upregulated LVEF,LVFS,and LVIDs,and improved the coordina-tion of LV wall fluctuations in the model group of rats;cardiac enzymes LDH and CK-MB levels increased,and levels of inflammatory factors TNF-α,IL-6,and IL-1 β were reduced,exerting cardioprotective effects;HE staining showed that myocardial tissue cell gap was re-duced,myocardial fiber breakage was reduced,cardio-myocyte arrangement tended to be normal,and inflam-matory cell infiltration was reduced;NF-κB p65 entry into the nucleus was reduced,and phosphorylated NF-κB p65(p-NF-κB p65)expression was reduced;and Western blot results showed that the expression of TLR4,MyD88,and NLRP3 proteins was reduced.Conclusions Tilianin pretreatment reduces serum my-ocardial enzymes and inflammatory factors and im-proves myocardial injury in rats with septicemia-in-duced myocardial injury,which may be related to the Tilianin anti-TLR4/NF-κB/NLRP3 inflammatory signa-ling pathway.

This study aims to investigate the epidemic variation of porcine circovirus type2(PCV2)and its distribution in swine farms in Henan Province from 2022 to 2023.In this study,1 206 pig blood samples from 18 urban scale swine farms,and 318 pigs and environmental samples from 2 PCV2-positive swine farms in Henan Province were detected by fluorescence quantitative PCR.ORF2 gene sequencing and genetic evolution analysis were performed on the positive samples.The results showed that the positive rate of PCV2 was 7.05％(85/1 206)in Henan Province,11.15％in western Henan Province and 3.03％in southern Henan Province.The positive rate of PCV2 in spring was 11.60％(67/576).A total of 31 ORF2 gene sequences were obtained,of which 23 were PCV2d(74.19％),6 were PCV2a(19.35％),one was PCV2b(3.23％)and one was PCV2c(3.23％).The results of amino acid sequence comparison showed that the mutation sites mainly concentrated on amino acids at positions 40-68 and 180-209.The total positive rate of pig farm sam-ples was 37.42％(119/318),and the positive rate of pig samples from different types of pig houses was 60.71％(34/56),45.83％(11/24),35.09％(20/57),and 33.33(3/9)in order from high to low.The positive rate of environmental samples from high to low was 56.36％(31/55)in feeding system,46.67％(7/15)in feces system,12.50(1/8)in decontamination area,11.11％(2/18)in living area,and no PCV2 was detected in ventilation system.The highest positive rate was 45.00％(9/20)for the tools in the house,7.14％(1/14)for the surface and sole of the clothes after leaving the house,and no PCV2 was detected on the surface and sole of the clothes before entering the house.In this study,the epidemiological investigation of PCV2 in Henan Province and its distribu-tion in swine farms were carried out,and the main circulating strains,seasons,regions and gene mutations of PCV2 in H enan Province were identified.The distribution and transmission routes of PCV2 in positive pig farms were preliminarily analyzed and summarized,which provided data basis and reference for effective prevention and control of PCV and the establishment of accurate bio-safety prevention and control measures.

Objective To observe the origin and course of the obturator artery(OA),so as to provide anatomical reference for reducing hemorrhage during pelvic surgery and pubic fracture fixation.Methods A total of 65 human hemi-pelvises specimens with intact structure were dissected to observe the origin,course and other variations of OA.Measure the length of the inner section of OA basin and the outer diameter at the origin,etc.Results OA originated from the internal iliac artery in 57 cases(87.7%),including 3 cases(4.6%)of the superior gluteal artery,5 cases(7.7%)of the inferior gluteal artery,3 cases(4.6%)of the external iliac artery and 5 cases(7.7%)of the inferior epigastric artery.OA participated in the formation of the arterial trunk in 3 cases(4.6%).The length of the pelvic segment of the OA in male and female was(50.87±15.41)mm and(51.71±14.19)mm,respectively,with no statistically significant difference between them(P>0.05).The outer diameters at the origin of the OA in male and female were(2.79±1.05)mm and(2.35±0.86)mm,and there was no statistically significant difference between them(P>0.05).Conclusion OA mainly originated from the anterior trunk of the internal iliac artery,with a few OA originated from the branches of the posterior trunk or the inferior epigastric artery,or participated in the formation of the arterial trunk.In pelvic surgery involving OA area,attention should be paid to the length of its pelvic segment and the outer diameter at the origin of OA,so as to better locate and protect blood vessels during surgery.

Objective To explore the safety and feasibility of mechanical thrombectomy as the first-line endovascular strategy in patients with non-acute symptomatic long-segment internal carotid artery occlusion(ICAO)undergoing revascularization.Methods This study retrospectively and consecutively enrolled non-acute symptomatic long-segment ICAO patients treated in the Department of Neurology,First Hospital of Jilin University,between January 2019 and August 2023,with mechanical thrombectomy as the preferred endovascular modality.Baseline and clinical data were collected,including sex,age,stroke-related risk factors(hypertension,diabetes,dyslipidemia,coronary artery disease,prior stroke,smoking and alcohol use history),admission National Institutes of Health stroke scale(NIHSS)score,pre-operative modified Rankin scale(mRS)score,time from last symptom onset to femoral puncture,time from imaging confirmation to femoral puncture,high-resolution MRI,right-sided ICAO,stump morphology(absent,tapered,flat/blunt,irregular),distal backfilling patterns(above ophthalmic segment,cavernous/clinoid segment,below cavernous segment),pathogenesis(atherosclerosis,dissection),types of anesthesia(local,general),procedure time(time frame from femoral puncture to recanalization or final angiography),site of the original occlusion in successfully recanalized cases,surgical techniques(aspiration+balloon angioplasty,aspiration+balloon angioplasty+stent-retriever thrombectomy,aspiration+balloon angioplasty+stent placement,aspiration+balloon angioplasty+stent-retriever thrombectomy+stent placement),stent placement(yes/no),number of stents implanted,and number of cases with retrieved thrombus,observed indicators.Observed indicators including ratio of technical successful recanalization(immediately post-procedure most severely stenosed site stenosis rate＜50%,expanded thrombolysis in cerebral infarction[eTICI]grade≥2c),intraoperative complications(distal embolization,symptomatic intracranial hemorrhage,arterial perforation)rate,perioperative mortality rate,30-day stroke recurrence,and 90-day mRS score.Compare the baseline data,clinical data and observational indicators of the patients with successful and unsuccessful recanalization.Base on the original occlusion site,successfully recanalized patients were subclassified into isolated extracranial,isolated intracranial,and tandem lesions patients,and their baseline characteristics and observation indicators were compared.Results(1)A total of 65 patients were enrolled(57 men,8 women;age 39-80 years;median 59[52,65]years)in this study.Technical success was achieved in 52cases(80%).Perioperative complications occurred in 4 patients(6.2%),with 3 distal embolization cases(4.6%),1(1.5%)developed symptomatic intracranial hemorrhage,and no arterial perforations were observed.There was no perioperative mortality.The 30-day stroke recurrence rate was 7.7%(5/65).90-day mRS scores ranged from 0 to 4,with a median of 1.0(0.0,1.5).(2)Baseline and clinical characteristics as well as outcome indicators did not differ significantly between patients with successful versus unsuccessful recanalization in the cohort undergoing mechanical thrombectomy for non-acute symptomatic long-segment intracranial carotid artery occlusion(all P＞0.05).(3)Among successfully recanalized patients,17(32.7%)had isolated extracranial lesions,18(34.6%)had isolated intracranial lesions,and 17(32.7%)had tandem lesions.All cases in the extracranial lesions group had original lesion site at the origin of internal carotid artery(C1,17/17).The intracranial group most often had orginal lesion sites at the C4 segment(9/18),whereas tandem lesions predominantly involved C1 plus C4-C5(16/17).Among the three groups,patients with isolated intracranial lesions were younger(57[48,61]years vs.60[52,64],63[58,69]years,P=0.050),and had a lower proportion of right-sided ICAO(4/18 vs.11/17 vs.11/17,P=0.032),while patients with tandem lesions required a greater number of stents(2.0[1.0,2.0]vs.1.0[1.0,1.5],1.0[0.8,2.0],P=0.013).Significant differences were observed in the proportion of patients with retrieved thrombus decreased progressively from patients with isolated extracranial,isolated intracranial to tandem lesions(17/17 vs.17/18 vs.12/17,P=0.024).No significant differences were observed among lesion-site groups with respect to medical history,stump morphology,distal retrograde flow,procedural technique,procedure duration,anesthesia method,or outcome indicators(all P＞0.05).Conclusions This study suggested that utilizing mechanical thrombectomy as the first-line endovascular therapy for non-acute symptomatic long-segment ICAO is safe and feasible.The original occlusive sites of non-acute symptomatic long-segment ICAO predominantly involve the cervical origin and the cavernous segment of the internal carotid artery.The conclusions of this study require further validation.
