Predictive value of Pcv-aCO 2 on left ventricular ejection fraction in myocardial infarction / 中华急诊医学杂志

Objective:To investigate the relationship between central venous-arterial blood carbon dioxide partial pressure difference (Pcv-aCO 2) and left ventricular ejection fraction(LVEF) in acute myocardial infarction. Methods:Clinical data of patients with acute myocardial infarction admitted to the Intensive Care Unit of Fujian Provincial Hospital from November 2019 to October 2021 were retrospectively analyzed. LVEF was measured by bedside echocardiogram. The patients were divided into the normal LVEF group (LVEF ≥ 52%) and decreased LVEF group (LVEF < 52%) according to LVEF. The differences in general information and hemodynamic parameters between the two groups were compared. The normality of the above data was tested by the Jarque-Bera test. Correlation analysis of hemodynamic indices with LVEF was performed. Binary logistic regression was used to analyze the risk factors associated with the decrease in LVEF. The feasibility of diagnosing LVEF decline with Pcv-aCO 2 was assessed using receiver operating characteristic (ROC) curve. Results:Seventy-two patients with acute myocardial infarction were included for analysis, including 25 patients in the normal LVEF group and 47 patients in the decreased LVEF group. Pcv-aCO 2 was significantly higher in the decreased LVEF group than that in the normal LVEF group [(7.13±1.19) mmHg vs. (5.41±1.23) mmHg, P<0.01]. There was a negative correlation between LVEF and Pcv-aCO 2 ( rs= -0.740, P<0.01). The area under the ROC curve for Pcv-aCO 2 was 0.849 (95% CI: 0.758-0.939, P<0.01). The binary logistic regression analysis showed that Pcv-aCO 2 was an independent risk factor for decreased LVEF ( OR=2.251, 95% CI: 1.326-3.820). Conclusions:To a certain extent, the increase of Pcv-aCO 2 can predict the decrease of LVEF in acute myocardial infarction.

Identification and 3D architecture analysis of the LIPC gene mutation in a pedigree with familial hypercholesterolemia-like phenotype / 中华心血管病杂志

Objective: To identify and analyze 3D architecture of the mutational sites of susceptible genes in a pedigree with familial hypercholesterolemia-like phenotype (FHLP). Methods: This is a case series study. A pedigree with suspected familial hypercholesterolemia was surveyed. The proband admitted in Beijing Anzhen Hospital in April 2019. Whole-exome sequencing was performed to determine the mutational sites of susceptible genes in the proband. Polymerase chain reaction (PCR) sequencing was used to verify the pathogenic variant on proband's relatives. The structural and functional changes of the proteins were analyzed and predicted by Discovery Studio 4.0 and PyMol 2.0. Results: The patients in the pedigree showed abnormal lipid profiles, especially elevated levels of total cholesterol(TC). The genetic screening detected the c.1330C>T SNP in the exon 8 of lipase C (LIPC) gene, this mutation leads to an amino acid substitution from arginine to cysteine at position 444 (Arg444Cys), in the proband and proband's father and brother. In this family, members with this mutation exhibited elevated TC, whereas lipid profile was normal from the proband's mother without this mutation. This finding indicated that LIPC: c.1330C>T mutation might be the mutational sites of susceptible genes. The analysis showed that Arg444Cys predominantly affected the ligand-binding property of the protein, but had a limited impact on catalytic function. Conclusion: LIPC: c.1330C>T is a new mutational site of susceptible genes in this FHLP pedigree.

MethodsA total of 671 patients with hepatitis B virus infection， who were admitted to the outpatient and inpatient departments of Dongzhimen Hospital of Beijing University of Chinese Medicine and The Fifth Medical Center of Chinese PLA General Hospital from July 1st， 2020 to June 30th， 2021， were included， involving 120 cases of CHB， 340 cases of hepatitis B liver cirrhosis （HBLC）， 64 cases of precancerous lesions with hepatitis B liver cirrhosis （PLHC）， and 147 cases of hepatitis B liver cirrhosis with hepatocellular carcinoma （HCC）. A Survey form of traditional Chinese medicine syndrome during malignant transformation of chronic hepatitis B was designed， and the general information， auxiliary examination and the four examinations results were collected. Factor analysis and K-means clustering were used to determine and statistically analyze the syndrome and syndrome elements. ResultsFive traditional Chinese medicine （TCM） syndrome types were identified in CHB patients， while there were six TCM syndrome types in HBLC， PLHC and HCC stages. Among CHB patients， the main syndromes were liver constraint and spleen deficiency （53.33%） and liver-gallbladder damp-heat （21.67%）， and the dominant syndrome elements were qi stagnation （27.60%）， heat （17.71%） and qi deficiency （17.71%）. In the HBLC stage， the syndromes were mainly blood stasis obstructing the collaterals （23.83%） and liver constraint and spleen deficiency （22.35%）， with dominant syndrome elements being blood stasis （19.25%）， dampness （17.46%）， and qi deficiency （15.01%）. For the PLHC stage， the primary syndrome types were blood stasis obstructing the collaterals （29.68%） and liver-kidney yin deficiency （20.31%）， and the leading syndrome elements were blood stasis （22.12%）， yin deficiency （15.93%）， and qi deficiency （15.04%）. In the HCC stage， the syndrome was dominated by blood stasis obstructing the collaterals （33.34%） and liver-kidney yin deficiency （19.73%）， with the main syndrome elements being blood stasis （24.52%）， yin deficiency （16.09%）， and qi deficiency （15.33%）. During the progression of CHB to malignancy， there was a gradual decrease in excess syndromes including liver-gallbladder damp-heat and water-dampness internal obstruction from 21.67% to 19.04%. In contrast， deficiency syndromes including liver-kidney yin deficiency and spleen-kidney yang deficiency increased from 15.83% to 31.97%. Additionally， excess syndrome elements including qi stagnation， heat and dampness decreased from 59.89% to 34.48%， while deficiency syndrome elements including qi deficiency， yin deficiency and yang deficiency increased from 32.30% to 41.00%. ConclusionDuring the malignant transformation of CHB， there exists a progression of syndrome and syndrome elements， shifting from qi stagnation， heat and qi deficiency to blood stasis （predominantly excess）， dampness and qi deficiency， and then to blood stasis （predominantly deficiency）， yin deficiency and qi deficiency， characterized by “deficiency-excess complex， and shift from excess to deficiency”.

Objective:To investigate the clinical manifestations and related risk factors of patients with Pseudomonas aeruginosa (PAE) bloodstream infection, and to provide references for clinical diagnosis and treatment of PAE bloodstream infection after combining with bacterial resistance condition. Methods:The clinical data and biological data of all patients with PAE bloodstream infection who received treatment in the Third Affiliated Hospital of Wenzhou Medical University from January 2019 to December 2020 were analyzed retrospectively. The independent influential factors of PAE bloodstream infection were analyzed using binary logistic regression. Results:Eighty-three patients had PAE bloodstream infection. Among them, 71 patients were included in the final analysis. Among the 71 patients, 36 patients (50.70%) had carbapenem-resistant Pseudomonas aeruginosa ( CRPA). Univariate analysis showed that the history of hospitalization within 90 days ( χ2 = 3.90, P = 0.048), indwelling catheterization ( χ2 = 5.08, P = 0.024), septic shock ( χ2 = 4.00, P = 0.046), mechanical ventilation ( χ2= 12.35, P < 0.001), deep venous catheter ( χ2 = 4.08, P = 0.043), acute physiology and chronic health evaluation score II ≥ 10 points ( χ2 = 4.06, P = 0.044), and multi-drug resistance ( χ2 = 11.75, P = 0.001) were the suspicious influential factors of CRPA bloodstream infection. Multivariate logistic regression analysis showed that mechanical ventilation was an independent risk factor for CRPA bloodstream infection ( OR = 7.43, 95% CI 1.182-46.674, P = 0.032). Multi-drug resistance was an independent risk factor for CRPA bloodstream infection ( OR = 5.842, 95% CI 1.520-22.450, P = 0.010). Conclusion:Mechanical ventilation and multi-drug resistance are the independent influential factors of CRPA bloodstream infection. Invasive operations such as mechanical ventilation should be avoided in the clinic.

Immunomodulatory Biomaterials and Emerging Analytical Techniques for Probing the Immune Micro-Environment

After implantation of a biomaterial, both the host immune system and properties of the material determine the local immune response. Through triggering or modulating the local immune response, materials can be designed towards a desired direction of promoting tissue repair or regeneration. High-throughput sequencing technologies such as single-cell RNA sequencing (scRNA-seq) emerging as a powerful tool for dissecting the immune micro-environment around biomaterials, have not been fully utilized in the field of soft tissue regeneration. In this review, we first discussed the procedures of foreign body reaction in brief. Then, we summarized the influences that physical and chemical modulation of biomaterials have on cell behaviors in the micro-environment. Finally, we discussed the application of scRNA-seq in probing the scaffold immune micro-environment and provided some reference to designing immunomodulatory biomaterials. The foreign body response consists of a series of biological reactions. Immunomodulatory materials regulate immune cell activation and polarization, mediate divergent local immune micro-environments and possess different tissue engineering functions. The manipulation of physical and chemical properties of scaffolds can modulate local immune responses, resulting in different outcomes of fibrosis or tissue regeneration. With the advancement of technology, emerging techniques such as scRNA-seq provide an unprecedented understanding of immune cell heterogeneity and plasticity in a scaffold-induced immune micro-environment at high resolution. The in-depth understanding of the interaction between scaffolds and the host immune system helps to provide clues for the design of biomaterials to optimize regeneration and promote a pro-regenerative local immune micro-environment.

Objective:To investigate the effects of heme oxygenase-1 (HO-1) on hepatic sinusoidal endothelial cells (LSECs) proliferation, migration, and hepatocyte proliferation.Methods:Eighteen male C57BL/6 mouse aged 6-8 weeks old were underwent partial hepatectomy. Cell proliferation and HO-1 expression in residual liver tissue were detected by immunofluorescence histochemistry at 0 d, 2 d and 4 d after operation. In vitro, LSECs were transfected with adenovirus carrying HO-1 gene (HO-1 group), and the cells were transfected with empty vector adenovirus and the non-transfected cells were used as control. In addition, LSECs from different transfection groups were co-cultured with hepatocyte without contact to evaluate the effect of HO-1 expression on promoting hepatocyte proliferation. Western Blotting and RT-PCR were used to detect the protein and mRNA expression of HO-1, inhibitor of DNA binding and or differentiation (Id1), hepatocyte growth factor (HGF) and Wnt2. Cell proliferation was detected by EdU. The ability of cell migration was detected by Transwell migration assay.Results:Compared with 0 d after hepatectomy, LSECs proliferation and HO-1 expression within LSECs were increased significantly at 4 d after surgery. EdU positive rate of LSECs in HO-1 group (27.20±4.80)% was higher than that in empty vector group (12.47±3.30)% and non-transfected group (15.97±2.50)%. The number of LSECs migration in HO-1 group (258.70±36.56) was higher than that in empty vector group (122.00±38.16) and non-transfected group (107.70±30.01). The protein and mRNA expression level of HO-1, Id1, HGF and Wnt2 in HO-1 group were higher than that in empty vector group and non-transfected group. EdU positive rate of hepatocytes that co-cultured with LSECs in HO-1 group (18.33±2.52) % was higher than that in empty vector group (11.33±1.53)% and non-transfected group (11.7±2.08)%. The differences were statistically significant (all P<0.05). Conclusion:Up-regulation of HO-1 promoted LSECs proliferation and migration of, as well as up-regulation of HO-1 in LSECs enhanced the capacity of LSECs to promote hepatocyte proliferation.

Risk stratification and low-density lipoprotein cholesterol goal attainment rates in patients with very high-risk or extreme high-risk atherosclerotic cardiovascular diseases regarding three guidelines / 中华内科杂志

Objective:To explore the differences of risk stratification of very high-risk or extreme high-risk atherosclerotic cardiovascular diseases (ASCVD) and the attainment rates of low-density lipoprotein cholesterol (LDL-C) management targets evaluated by three different criteria, and the causal attributions of these differences.Methods:Patients with ASCVD were consecutively enrolled from January 1 to December 31 in 2019, and were evaluated for very high-risk or extreme high-risk and LDL-C goal attainment rates with 2018 American guideline on the management of blood cholesterol (2018AG), 2019 China Cholesterol Education Program (CCEP) Expert Advice for the management of dyslipidemias (2019EA) and 2020 Chinese expert consensus on lipid management of very high-risk ASCVD patients(2020EC), respectively. The causal attributions of the differences in attainment rates were analyzed as well.Results:A total of 1 864 ASCVD patients were included in this study. According to 2018AG, 2019EA and 2020EC, the proportions of the patients with very high-risk or extreme high-risk were 59.4%, 90.7%, and 65.6%, respectively. The absolute LDL-C target attainment rates were 37.2%, 15.7%, and 13.7%, respectively, the differences between each two rates were statistically significant (all P<0.001). As to the differences in attainment rates between 2020EC and 2018AG, 61.5% were due to the different LDL-C goal attainment values and 38.5% were caused by the different risk stratifications, while for the differences between 2020EC and 2019EA attainment rates, different LDL-C goal attainment values were responsible for 13.2%, and different risk stratifications were responsible for 86.8% of the differences. Conclusions:There are significant differences in the proportions and LDL-C attainment rates among the three different criteria for very high-risk or extreme high-risk ASCVD. 2020EC showed a moderate proportion of patients with extreme high-risk, and had the lowest LDL-C attainment rate. The differences between 2020EC and 2018AG are mainly due to the LDL-C target values, and the differences between 2020EC and 2019EA are mainly caused by the risk stratifications.

Objective@#This study aimed to investigate whether cytokine profiles and virological markers might add value in monitoring the effects of peginterferon (PEG-IFN) therapy for hepatitis B e-antigen (HBeAg) positive chronic hepatitis B (CHB).@*Methods@#HBeAg positive patients with CHB were treated with PEG-IFN for 48 weeks. Clinical biochemical, and HBV serological indexes, as well as cytokines, were detected at baseline and every 12 weeks.@*Results@#A total of 116 patients with CHB were enrolled in this study; 100 patients completed the 48-week treatment and follow-up, of whom 38 achieved serum HBeAg disappearance, 25 achieved HBeAg seroconversion, 37 showed HBsAg decreases ≥ 1 log 10 IU/mL, 9 showed HBsAg disappearance, and 8 became HBsAb positive. The cytokine levels at baseline and during treatment were similar between the HBeAg disappearance group and non-disappearance group. The disappearance of HBeAg was independently associated with HBeAg levels at weeks 12 and 24, and with the HBeAg decline at week 24 ( P < 0.05). The HBsAg response was independently associated with HBsAg, the HBsAg decline, HBeAg, the HBeAg decline at week 12, and HBsAg at week 24 ( P< 0.05).@*Conclusion@#There was no significant correlation between the response to interferon (IFN) and cytokines during PEG-IFN treatment. The changes in virological markers predicted the response to IFN after 48 weeks.

A Case of Localized Amyloidosis of the Brachial Plexus / 罕见病研究

Localized peripheral neuropathy amyloidosis is a rare disease that mainly occurred in elder people who present with focal neurological symptoms. AL is the main type of amyloid protein. Biopsy is the golden standard for diagnosis. Mass spectrometry and immunohistochemical analysis help to confirm the type of amyloid protein. This paper retrospectively analyzes the clinical and imaging data, auxiliary examinations, histological, and immunohistochemical markers. The patient, a 34-year-old woman, presented with a right neck mass and weakness of the right arm. Brachial plexus magnetic resonance imaging (MRI) showed a tumor-like lesion in the nerve root at C5 and C6 and in upper trunk. Electrophysiological studies revealed damage in the upper trunk of the brachial plexus. Positive staining with Congo red was found in brachial plexus biopsy. Mass spectrometry showed that the type of amyloid protein was AHL(G-λ). The patient underwent nerve graft for treatment. Meanwhile, literature review revealed that the average onset age of localized spinal nerve amyloidosis was 62.4 years old.The radial nerve was the most susceptible, followed by the lumbosacral plexus.
