Objective To discuss the short-term efficacy of endovascular recanalization for symptomatic non-acute internal carotid artery occlusion.Methods A total of 90 patients with symptomatic non-acute internal carotid artery occlusion,who were admitted to the Department of Neurology of Tianjin Municipal Teda Hospital of China from August 2017 to December 2021,were selected as the research objects.The patients were divided into study group(n=45)and control group(n=45).Percutaneous endovascular recanalization of internal carotid artery occlusion was performed for the patients of the study group,and standardized antiplatelet aggregation and anti-lipid therapy(including oral aspirin,clopidogrel bisulphate and atorvastatin)was adopted for the patients of the control group.The symptom recurrence rate at one year after treatment in both groups was analyzed.Results Of the 45 patients in the control group,4 were lost in touch,and 41 completed the one-year follow-up.Of the 45 patients in the study group,2 patients had failure of surgery,one patient had lost contact visit,and 42 completed the one-year follow-up.Postoperative intracranial hemorrhage occurred in 2 patients.After one year of follow-up,in the control group 26 patients(63.41％)developed recurrence of symptoms,presenting as transient ischemic attack(TIA,n=13,31.7％)and cerebral infarction(n=13,31.7％),and in the study group 8 patients(4.76％)developed recurrence of symptoms,presenting as TIA(n=6,14.3％)and cerebral infarction(n=2,4.8％);the incidence of cerebral infarction in the study group was strikingly lower than that in the control group,and the difference between the two groups was statistically significant(P＜0.05).In the patients with grade Ⅲ compensation,the recurrence rate of symptoms was remarkably decreased after endovascular recanalization of internal carotid artery occlusion,and the difference between the two groups was statistically significant(P＜0.05).However,in the patients with grade Ⅰ or grade Ⅱ compensation,although the recurrence rate of symptoms was decreased after endovascular recanalization of internal carotid artery occlusion,the difference between the two groups was not statistically significant(P＞0.05).Conclusion For the treatment of patients with symptomatic non-acute internal carotid artery occlusion,percutaneous endovascular recanalization of internal carotid artery occlusion is clinically safe,it can significantly decrease the recurrence rate of symptoms.

Objective:To investigate the relationship between oxygen consumption (VO 2), carbon dioxide production (VCO 2), and Oxygen Consumption/lactate (VO 2/Lac) with risk of death in patients with severe ARDS. Methods:A retrospective cohort study method was used, and the study subjects were hospitalized for >5 days adult patients with severe ARDS in the central intensive care unit of Henan Provincial People's Hospital from 1 March 2020 to 30 June 2023. The following patients were excluded: IC test was not completed on the 4th day of ICU admission, IC test results were unreliable, mechanical ventilation duration had exceeded 48 h at the time of ICU transfer or admission, palliative care patients and pregnant and parturient women. Using indirect calorimetry to determine VO 2 and VCO 2 values on the 4th day of admission, reviewing medical records to obtain general condition, disease information, blood gas analysis (including lactate value), diagnostic and therapeutic measures, and following up deaths by telephone and time of death. The primary outcome measure was death at 90 days, and the secondary outcome measure was death at 28 days, length of stay in ICU, total length of stay, and total hospitalization cost. Cox regression analysis and linear regression analysis were used to investigate the relationship between VO 2, VCO 2, VO 2/Lac and primary and secondary outcome indexes. Results:A total of 216 patients were enrolled, 78 patients (36.1%) died and 138 patients (63.9%) survived at 90 days. After correction for confounders, the results of multifactorial Cox regression analysis suggested that compared with the Q4 group, HR (95% CI) for 90-day risk of death in the VO 2 Q1 and Q2 groups was 3.21 (1.38, 7.49) and 3.24 (1.42, 7.38), and HR (95% CI) for 90-day risk of death in the VCO 2 Q1, Q2 and Q3 groups was 5.88 (2.33, 14.84), 4.26 (1. 60, 11.34) and 3.54 (1.34, 9.35), respectively, and the HR (95% CI) for 90-day risk of death in the VO 2/Lac Q1, Q2 and Q3 groups were 8.72 (3.01, 25.25), 8.43 (2.91, 24.47) and 4.04 (1.34, 12.17) respectively. P-trends were all <0.05, indicating that VO 2, VCO 2 and VO 2/Lac were linearly and negatively associated with the risk of 90-day mortality. In addition, VO 2, VCO 2, and VO 2/Lac were negatively associated with 28-day risk of death and higher VO 2/Lac was negatively associated with length of ICU stay. Conclusions:VO 2, VCO 2 and VO 2/Lac were negatively associated with 90-day mortality risk and 28-day mortality risk in patients with severe ARDS and may be independent risk factors predicting mortality risk of such patients.

Objective:To explore the prognosis efficacy of psycho-cardiological therapy and management on patients with coronary atherosclerosis disease (CAD).Methods:This was a clinical randomized controlled study. This study included inpatients with CAD at the cardiology department in Beijing Anzhen Hospital, Capital Medical University from August 2021 to January 2024. The patients enrolled in this study were asked for basic information, and received measurements for depression, anxiety, sleep quality and living quality by the scales of Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder scale-7 (GAD-7), Athens Insomnia Scale (AIS), EuroQol 5-dimension 5-level (EQ-5D-5L) respectively. The patients were randomly grouped into a regular treatment group and a psycho-cardiological treatment group which included WeChat management or antidepressant/antianxiety medical therapy according to the situation. After the patients discharging from hospital for 2, 4, 12, 24, 48, 72, and 96 weeks, professional cardiovascular doctors would follow up by telephone, WeChat, and outpatient department, including scales (2-48 weeks), and cardiac events (2-96 weeks). Kaplan-Meier survival curve and multivariate Cox proportional hazards model were used for analyzing the association between psycho-cardiological treatment and cardiac events.Results:This study recruited a total of 552 patients with CAD, aged 61.0(54.0, 67.0) years, and 379 (68.7%) were male. There were 279(50.5%) in the regular treatment group and 273(49.5%) in the psycho-cardiological treatment group. After treatment for 4, 12 and 48 weeks, the PHQ-9 score in psycho-cardiological was significantly lower than the regular treatment group; After treatment for 12 weeks, the EQ-5D-5L effective value in psycho-cardiological group was higher than the regular treatment group; After treatment for 2, 4, 12, 24 and 48 weeks, the EQ-5D-5L VAS score in psycho-cardiological group was higher than the regular therapy group (all P<0.05). The Kaplan-Meier survival curve showed that, during the different follow-up periods, the rate of cardiac events in psycho-cardiological treatment group was lower than regular treatment group (log-rank P<0.001). The multivariate Cox proportional hazards model adjusted the factor of age, the psycho-cardiological treatment contributed to reducing the cardiac events rate by 80.3% ( HR=0.197, 95% CI: 0.067-0.582, P=0.003). Conclusion:Psycho-cardiological treatment is beneficial for improving psychological stress, living quality, and reducing cardiac events, and helps to improve prognosis and psycho-cardiological rehabilitation in CAD patients.

This article presented the maternal and infant outcomes of glycogen storage disease type Ⅲa (GSDⅢa) in a woman with full-term pregnancy. The woman exhibited symptoms of hypoglycemia when she was three months old, which were alleviated with intravenous glucose infusion. At the age of 19, during surgical treatment for scoliosis, she was found with liver cirrhosis, splenomegaly, and thrombocytopenia. Glycogen debranching enzyme deficiency was detected through liver biopsies, leading to the clinical diagnosis of GSDⅢ (unspecified genotype). The patient was admitted after conceiption due to "irregular lower abdominal pain for 1 day" at 34 weeks and 3 days. Through multidisciplinary management in the late pregnancy, which included medication adjustments, dietary instruction, and platelet transfusions both at half an hour before and during the operation, the patient underwent a cesarean section at 37 +1 weeks of gestation and delivered a healthy boy with normal Apgar scores at 1, 5, and 10 min. The mother followed a high-protein diet postpartum and the newborn experienced hypoglycemia after birth. Intravenous glucose was supplied to the infant, restabilizing his blood glucose. Maternal and neonatal blood glucose both remained stable. Postpartum whole-exome sequencing identified compound heterozygous variants in the mother, which were in the AGL gene at chr1:100379102-100379103 with gene variant information of NM_000642.2:c.3971_3972delAT(p.Tyr1324*) and at chr1:100345603 with gene variant information of NM_000642.2:c.1735+1G>T, confirming the diagnosis of GSDⅢa. The newborn carried a heterozygous variant in the AGL gene at chr1:100379102-100379103 with gene variant information of NM_000642.2:c.3971_3972delAT(p.Tyr1324*). Postpartum follow-ups showed stable blood glucose levels for the mother and normal growth and development for the newborn.

Objective To investigate the correlation between the residual cholesterol(RC)level and vertebrobasilar dilatation(VBD)in elderly patients with acute cerebral infarction(ACI).Methods A total of 325 elderly ACI patients admitted to Department of Neurology,Changzhou Second People's Hospital of Nanjing Medical University from January 2020 to July 2021 were recruited retrospectively.All of them underwent cranial MRI,CTA and biochemical test for plasma levels of TC,TG,LDL-C and HDL-C and other biochemical indicators.According to the imaging diagnostic criteria,they were divided into VBD group(52 cases)and non-VBD group(273 cases).Their clini-cal data were compared between the two groups,and the relationship between RC level and VBD was analyzed in the elderly ACI patients.Results Significant differences were observed in age,sex,hypertension,history of smoking and TC and RC levels between the VBD group and non-VBD group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that after adjus-ting the potential confounding factors,age(OR=1.126,95％CI:1.065-1.191,P=0.000),male(OR=4.163,95％CI:11.173-10.120,P=0.002),and RC level(OR=1.270,95％CI:1.151-1.401,P=0.000)were independent risk factors for VBD in elderly ACI patients.Conclusion Age,male and RC level are independent risk factors for VBD in elderly ACI patients.High RC lev-el may increase the risk of VBD.

Objective:To compare the clinical efficacy between radiofrequency ablation(RFA)and pulmonary metastasectomy in the colorectal cancer(CRC)patients with lung metastases after radical resection. Methods:The clinical data of 80 CRC patients with lung metastases after radical resection were analyzed retrospectively,and were divided into the surgery group(33 cases)and the RFA group(47 cases)according to the local treatment.The overall survival(OS)and progression-free survival(PFS)of the two groups were compared,as well as the prognostic factors of patients were analyzed. Results:The 3-year PFS and OS rates were 42.4％vs 31.9％and 75.8％vs 72.3％in the surgery group and the RFA group,respectively.There was no significant difference in PFS and OS between the two groups(P＞0.05).In multivariate analysis,maximum lung metastasis diameter,preoperative serum carcinoembryonic antigen(CEA)level and history of extrapulmonary metastasis were independent factors influencing OS in the CRC patients with lung metastases after radical resection(P＜0.05).In addition,preoperative serum carcinoembryonic antigen(CEA)level and history of extrapulmonary metastasis were also independent factors influencing PFS in the CRC patients with lung metastases after radical resection(P＜0.05). Conclusion:The short-term efficacy of RFA is comparable to that of pulmonary metastasectomy in the CRC patients with lung metastases after radical resection,and long-term follow-up studies are needed.

Objective:To investigate the role of serum hepatitis B virus RNA (HBV RNA) in predicting HBeAg serological conversion in children with chronic hepatitis B.Methods:175 children aged 1~17 years with chronic hepatitis B who received interferon α (IFNα) for 48 weeks were selected. Patients were divided into HBeAg seroconversion and non-conversion based on whether HBeAg seroconversion occurred at 48 weeks of treatment.T-test and Mann-Whitney U test were used to compare between groups; chisquare test or Fisher exact probability method was used to compare the frequency between groups of classified variables; and Pearson correlation was used to analyze the correlation between indicators. Univariate and multivariate logistic regression analyses were used to identify influencing factors associated with HBeAg serological conversion. The predictive effect of HBV RNA, HBV DNA, and HBsAg on HBeAg serological conversion was compared and analyzed by the receiver operating characteristic curve (ROC).Results:The seroconversion rate of HBeAg at 48 weeks was 36.0% (63/175). The reduction in HBVRNA levels from baseline to the 12th, 24th, 36th, and 48th weeks of antiviral therapy was significantly greater in the HBeAg serological conversion group than that in the non-conversion group, and the difference was statistically significant between the two groups (P < 0.05). Univariate and multivariate regression analyses showed that age and a decline in HBV RNA levels at week 12 were independent predictors of HBeAg serological conversion. The area under the ROC curve (AUROC) of HBV RNA decline at week 12 was 0.677(95% CI∶0.549-0.806, P = 0.012), which was significantly better than the same period of AUROC of HBV DNA (0.657, 95% CI∶0.527-0.788, P = 0.025) and HBsAg (0.660, 95% CI∶0.526-0.795, P = 0.023) decline. HBV RNA levels decreased (>1.385 log10 copies/ml) at week 12, with a positive predictive value of 53.2%, a negative predictive value of 72.2%, a sensitivity of 77.4%, and a specificity of 57.9% for HBeAg seroconversion. Conclusion:HBV RNA level lowering during the 12th week of antiviral therapy can serve as an early predictor marker for HBeAg serological conversion in children with chronic hepatitis B.

Although widely applied in treating hematopoietic malignancies, transplantation of hematopoietic stem/progenitor cells (HSPCs) is impeded by HSPC shortage. Whether circulating HSPCs (cHSPCs) in steady-state blood could be used as an alternative source remains largely elusive. Here we develop a three-dimensional culture system (3DCS) including arginine, glycine, aspartate, and a series of factors. Fourteen-day culture of peripheral blood mononuclear cells (PBMNCs) in 3DCS led to 125- and 70-fold increase of the frequency and number of CD34⁺ cells. Further, 3DCS-expanded cHSPCs exhibited the similar reconstitution rate compared to CD34⁺ HSPCs in bone marrow. Mechanistically, 3DCS fabricated an immunomodulatory niche, secreting cytokines as TNF to support cHSPC survival and proliferation. Finally, 3DCS could also promote the expansion of cHSPCs in patients who failed in HSPC mobilization. Our 3DCS successfully expands rare cHSPCs, providing an alternative source for the HSPC therapy, particularly for the patients/donors who have failed in HSPC mobilization.

Objective:To evaluate the value of transrectal ultrasound(TRUS)in diagnosing extramural venous invasion(EMVI) of rectal cancer.Methods:Clinical data of 81 rectal cancer patients were retrospectively analyzed in the People′s Hospital of Inner Mongolia Autonomous Region from January 2015 to December 2021. The extramural vascular sonographic features in these patients were summarized. Based on the postoperative pathology and compared with MRI examination, the efficacy of TRUS for the diagnosis of EMVI in rectal cancer was investigated.Results:①According to the sonographic presentation, extramural vessels of rectal cancer can be divided into the following four types: typeⅠshowed that the mass broke through the muscularis propria of the intestinal wall, and no peripheral vascular shadow was observed; typeⅡshowed that the mass broke through the muscularis propria, surrounded by extraneous vessels with normal diameter, running and blood flow; type Ⅲ showed that the mass broke through the intrinsic muscle layer of the intestinal wall and was surrounded by extramural vessels with abnormally thickened diameters, and blood flow filling defects; type Ⅳ showed a mass that broke through the intrinsic muscular layer, with irregularly dilated vessels outside the peritumoral wall and no blood flow signal in the lumen. ②With type Ⅲ and type Ⅳ as positive signs of EMVI, the diagnosis compliance rate of TRUS was 90.1% (Kappa=0.580, P<0.001), sensitivity was 58.3%, specificity was 95.7%, positive predictive value was 70.0%, negative predictive value was 93.0%, and area under the ROC curve(AUC) was 0.770. The diagnosis compliance rate of MRI was 86.4% (Kappa=0.541, P<0.001), sensitivity was 75.0%, specificity was 88.4%, positive predictive value was 52.9%, negative predictive value was 95.3%, and the AUC was 0.817. The differences in sensitivity and specificity between TRUS and MRI for the diagnosis of rectal cancer EMVI were not statistically significant ( P>0.05), and the differences in the AUC were not statistically significant ( Z=0.447, P=0.655). Conclusions:TRUS is valuable in assessing the extramural vascular status of rectal cancer and is expected to be an effective imaging method for preoperative diagnosis of EMVI.
