[Effect of intervertebral bone graft area on the effect of single-level posterior lumbar decompression and bone graft fusion].

OBJECTIVE: To study the effect of intervertebral grafting area on the effect of single segment lumbar posterior decompression and intervertebral bone grafting fusion. METHODS: The clinical data of 52 patients who underwent single-segment lumbar posterior decompression pedicle internal fixation and bone grafting fusion from January 2020 to December 2022 were retrospective reviewed. The area of the intervertebral bone graft was measured one week postoperatively using Computed Tomography (CT), and based on the ratio of the bone graft area to the average area of the endplates, the patients were divided into three groups:17 cases in group A(the intervertebral bone graft area did not exceed the area of one pedicle) included 9 males and 8 females with an average age of (56.0±11.5) years old;15 cases in group B(the intervertebral bone graft area exceeded one pedicle but did not reach the opposite pedicle) included 10 males and 5 females with an average of (52.0±14.0) years old; 20 cases in group C (the intervertebral bone graft area exceeded the opposite pedicle) included 12 males and 8 females with an average of (49.5±12.8) years old. X-rays and CT scans were performed at 3, 6, 12 months, and the final follow-up postoperatively, the interbody fusion Brantigan scores, pain visual analogue scale (VAS), and Oswestry Disability Index (ODI) at each follow-up were recorded. RESULTS: The gender, age, and surgical segments showed no significant differences among three groups(P>0.05). There was also no significant difference in the preoperative VAS and ODI among three groups (P>0.05). All patients of three groups were followed up from 12 to 36 months. Compared with preoperative, VAS and ODI scores of three groups showed significant improvement at 1 week postoperatively and the final follow-up (P<0.05). Compared with preoperative measurements, the height of the intervertebral space was restored at 1 week postoperatively in three groups;at the final follow-up, the loss of height in the intervertebral space was less in groups B and C, and the height of the intervertebral space in group B and C was significantly higher than in group A(P<0.05). The modified Brantigan scores at 3 and 6 months postoperatively were significantly higher in group C than in groups A and B (P<0.05);at 12 months postoperatively, the scores in groups B and C were significantly higher than in group A(P<0.05);however, at the final follow-up, there was no significant difference in the modified Brantigan scores among three groups(P>0.05). The bone graft fusion rate in group C was significantly higher than in groups A and B at 3 months postoperatively(P<0.05);at 6 and 12 months postoperatively, the fusion rates in groups B and C were significantly higher than in group A(P<0.05);at the final follow-up, the fusion rate in group A was still lower than in groups B and C, but the difference among three groups was not significant(P>0.05). CONCLUSION: Single segment posterior lumbar decompression and interbody fusion surgery can significantly improve the clinical symptoms of patients with lumbar degenerative related diseases. However, as the proportion of bone grafting area increases, the early bone grafting fusion rate and fusion score of patients are significantly improved.

Successful treatment of a severe Takotsubo syndrome case complicated by liver abscess.

The main manifestations of Takotsubo syndrome (TTS) are a spherical expansion of the left ventricle or near the apex and decreased systolic function. TTS is mostly thought to be induced by emotional stress, and the induction of TTS by severe infection is not often reported. A 72-year-old female patient with liver abscess reported herein was admitted due to repeated fever with a history of hypertension and impaired glucose tolerance. Her severe infection caused TTS, and her blood pressure dropped to 80/40 mmHg. IABP treatment was performed immediately and continued for 10 days, and comprehensive medication was administered. Based on her disease course and her smooth recovery, general insights and learnings may be: Adding to mental and other pathological stress reaction, serious infections from pathogenic microorganism could be of great important causation of stress reaction leading to TTS, while basic diseases such as coronary heart disease, hypertension, and diabetes were be of promoting factors; In addition to effective drug therapies for TTS, the importance of the timely using of IABP should be emphasized.

Effects of polysorbates on stability of monoclonal antibody drugs / 中国生物制品学杂志

@#Objective To evaluate the effects of various polysorbates(PS)on the stability of different types of monoclonal antibody(mAb)drugs.Methods Three types of monoclonal antibodies mAbA(IgG1 proantibody drug),mAbB(IgG1 mAb)and mAbC(IgG1 mAb with Fc N297A mutation)were used as model proteins,and different kinds or contents of PS were added into the mAb formulations respectively to investigate the influencing factors.The effects of PS on the stability of mAb drugs were evaluated comprehensively by detecting the changes of quality attributes,such as protein aggregates and insoluble particles.Results PS20 and PS80 showed no significant difference in inhibiting the formation of aggregates and charge variants in the three mAbs(P>0.05),while the addition of PS80 in mAbB and PS20 in mAbC significantly inhibited the increase of insoluble particles respectively(P<0.05);The content of PS20 showed a significant effect on the detection indexes of charge variants and insoluble particles in mAbC(P<0.05).Conclusion Different types of mAbs have different sensitivities to various kinds and contents of PS.Therefore,when designing the formulation of mAbs,it is necessary to select appropriate kinds and contents of PS to further improve the stability of mAb drugs.

[Clinical efficacy and radiation exposure analysis of vertebroplasty and curved vertebroplasty in the treatment of osteoporotic vertebral compression fracture].

OBJECTIVE: Taking the classic bilateral puncture vertebroplasty as a reference, to evaluate the clinical efficacy of vertebroplasty of the curved-angle puncture device, analyze the radiation exposure of patients and surgeons during the operation and summarize the protective measures. METHODS: The clinical data of 49 patients with osteoporotic vertebral compression fractures admitted from March 2018 to September 2019 were retrospectively analyzed. According to the different surgical puncture methods, 49 patients were divided into vertebroplasty group (using classic bilateral puncture) and curved vertebroplasty group (using curved angle puncture). Among them, there were 26 cases in vertebroplasty group, including 7 males and 19 females, aged (73.25±6.36) years, 2 cases in thoracic segment, 21 cases in thoracolumbar segment, and 3 cases in lumbar segment. In curved vertebroplasty group, there were 23 cases, including 6 males and 17 females, aged (73.09±6.52) years, 3 cases in thoracic segment, 19 cases in thoracolumbar segment, and 1 case in lumbar segment. The operation time and the amount of injected bone cement in the two groups were recorded. Visual analogue scale (VAS) and modified Oswestry Disability Index (ODI) were respectively used to assess the pain degree and lumbar function, the postoperative bone cement leakage or other complications were observed. The radiation doses of the two groups of patients and surgeons were compared. RESULTS: All 49 patients were followed up for 10-22 (14.55±3.83) months. Eleven cases in vertebroplasty group and 9 cases in curved vertebroplasty group occurred bone cement leakage after surgery, and there was no statistically significant difference between two groups. VAS scores of vertebroplasty group were 6.23±0.68 before operation and 1.69±0.47 at 1 day after operation, respectively, modified ODI were (72.59±3.25)% and (33.59±2.85)%. The preoperative and postoperative VAS scores of curved vertebroplasty group were 6.46±0.56 and 1.57±0.49, respectively, modified ODI were (73.21±3.18)% and (33.17±2.37)%. The postoperative pain degree and lumbar function of the two groups were significantly improved, but the difference between the groups was not statistically significant. The operation time of curved vertebroplasty group and vertebroplasty group were (17.27±9.58) min and(23.19±8.56) min, and the amount of injected bone cement were (4.91±1.49) ml and (6.58±1.42) ml. Obviously, curved vertebroplasty group has more advantages in operation time and the amount of injected bone cement. In curved vertebroplasty group, the radiation dose of the operator was (0.53±0.05) mSv and the patient was (10.64±1.65) mSv;in vertebroplasty group, the operator was (0.59±0.08) mSv andthe patient was (13.52±1.81) mSv. The radiation dose of patients in curved vertebroplasty group was significantly lower than that of the vertebroplasty group, but there was no statistically significant difference in the operator between two groups. CONCLUSION: Both puncture methods can achieve satisfactory clinical results, but curved angle puncture can optimize the distribution of bone cement and reduce the radiation dose of patients.

Impact of Prior Digestive System Disease on In-Hospital Gastrointestinal Bleeding in Patients with Acute Myocardial Infarction.

OBJECTIVE: Patients presenting with acute myocardial infarction (AMI) with prior digestive system disease are more likely to suffer from gastrointestinal (GI) bleeding than those without these diseases. However, few articles reported how the different conditions of the digestive tract produced different risks of GI bleeding. METHODS: A single-center study on 7464 patients admitted for AMI from December 2010 to June 2019 in the Beijing Chaoyang Heart Center was retrospectively examined. Patients with major GI bleeding (n = 165) were compared with patients without (n = 7299). Univariate and multivariate logistic regression models were constructed to test the association between GI bleeding and prior diseases of the digestive tract, including gastroesophageal reflux disease, chronic gastritis, peptic ulcer, hepatic function damage, diseases of the colon and rectum, and gastroenterological tract tumors. RESULTS: Of the 7464 patients (mean age, 63.4; women, 25.6%; STEMI, 58.6%), 165 (2.2%) experienced major GI bleeding, and 1816 (24.3%) had a history of digestive system disease. The risk of GI bleeding was significantly associated with peptic ulcer (OR = 4.19, 95% CI: 1.86-9.45) and gastroenterological tumor (OR = 2.74, 95% CI: 1.07-7.04), indicated by multivariate logistic regression analysis. CONCLUSION: Preexisting peptic ulcers and gastroenterological tract tumors rather than other digestive system diseases were indicators of gastrointestinal bleeding in patients with AMI who undergo standard antithrombotic treatment during hospitalization.

The long-term impact of a chronic total occlusion in a non-infarct-related artery on acute ST-segment elevation myocardial infarction after primary coronary intervention.

OBJECTIVES: To investigate the long-term outcome of patients with acute ST-segment elevation myocardial infarction (STEMI) and a chronic total occlusion (CTO) in a non-infarct-related artery (IRA) and the risk factors for mortality. METHODS: The enrolled cohort comprised 323 patients with STEMI and multivessel diseases (MVD) that received a primary percutaneous coronary intervention between January 2008 and November 2013. The patients were divided into two groups: the CTO group (n = 97) and the non-CTO group (n = 236). The long-term major adverse cardiovascular and cerebrovascular events (MACCE) experienced by each group were compared. RESULTS: The rates of all-cause mortality and MACCE were significantly higher in the CTO group than they were in the non-CTO group. Cox regression analysis showed that an age ≥ 65 years (OR = 3.94, 95% CI: 1.47-10.56, P = 0.01), a CTO in a non-IRA(OR = 5.09, 95% CI: 1.79 ~ 14.54, P < 0.01), an in-hospital Killip class ≥ 3 (OR = 4.32, 95% CI: 1.71 ~ 10.95, P < 0.01), and the presence of renal insufficiency (OR = 5.32, 95% CI: 1.49 ~ 19.01, P = 0.01), stress ulcer with gastraintestinal bleeding (SUB) (OR = 6.36, 95% CI: (1.45 ~ 28.01, P = 0.01) were significantly related the 10-year mortality of patients with STEMI and MVD; an in-hospital Killip class ≥ 3 (OR = 2.97,95% CI:1.46 ~ 6.03, P < 0.01) and the presence of renal insufficiency (OR = 5.61, 95% CI: 1.19 ~ 26.39, P = 0.03) were significantly related to the 10-year mortality of patients with STEMI and a CTO. CONCLUSIONS: The presence of a CTO in a non-IRA, an age ≥ 65 years, an in-hospital Killip class ≥ 3, and the presence of renal insufficiency, and SUB were independent risk predictors for the long-term mortality of patients with STEMI and MVD; an in-hospital Killip class ≥ 3 and renal insufficiency were independent risk predictors for the long-term mortality of patients with STEMI and a CTO.

KAT2A Promotes Hepatitis B Virus Transcription and Replication Through Epigenetic Regulation of cccDNA Minichromosome.

Hepatitis B virus (HBV) infection remains a major health problem worldwide. Sufficient maintenance of the HBV covalently closed circular DNA (cccDNA), which serves as a template for HBV transcription, is responsible for the failure of antiviral therapies. While accumulating evidence suggests that cccDNA transcription is regulated by epigenetic machinery, particularly the acetylation and methylation of cccDNA-bound histone 3 (H3) and histone 4 (H4), the potential contributions of histone succinylation and related host factors remain obscured. Here, by screening a series of succinyltransferases and desuccinylases, we identified KAT2A as an important host factor of HBV transcription and replication. By using HBV-infected cells and mouse models with HBV infection, KAT2A was found to affect the transcriptional activity of cccDNA but did not affect cccDNA production. Mechanism studies showed that KAT2A is mainly located in the nucleus and could bind to cccDNA through interaction with HBV core protein (HBc). Moreover, we confirmed histone H3K79 succinylation (H3K79succ) as a histone modification on cccDNA minichromosome by using the cccDNA ChIP-Seq approach. Importantly, KAT2A silencing specifically reduced the level of cccDNA-bound succinylated H3K79. In conclusion, KAT2A promotes HBV transcription and replication through epigenetic machinery, and our findings may provide new insight into the treatment of HBV infection.

Arabidopsis exoribonuclease USB1 interacts with the PPR-domain protein SOAR1 to negatively regulate abscisic acid signaling.

Signaling by the phytohormone abscisic acid (ABA) involves pre-mRNA splicing, a key process of post-transcriptional regulation of gene expression. However, the regulatory mechanism of alternative pre-mRNA splicing in ABA signaling remains largely unknown. We previously identified a pentatricopeptide repeat protein SOAR1 (suppressor of the ABAR-overexpressor 1) as a crucial player downstream of ABAR (putative ABA receptor) in ABA signaling. In this study, we identified a SOAR1 interaction partner USB1, which is an exoribonuclease catalyzing U6 production for spliceosome assembly. We reveal that together USB1 and SOAR1 negatively regulate ABA signaling in early seedling development. USB1 and SOAR1 are both required for the splicing of transcripts of numerous genes, including those involved in ABA signaling pathways, suggesting that USB1 and SOAR1 collaborate to regulate ABA signaling by affecting spliceosome assembly. These findings provide important new insights into the mechanistic control of alternative pre-mRNA splicing in the regulation of ABA-mediated plant responses to environmental cues.

An elevated monocyte-to-high-density lipoprotein-cholesterol ratio is associated with mortality in patients with coronary artery disease who have undergone PCI.

BACKGROUND: The aim of the present study was to investigate the association between the monocyte-to-high-density lipoprotein-cholesterol ratio (MHR) and the outcomes of patients with coronary artery disease (CAD) who were treated with percutaneous coronary intervention (PCI). METHODS: A total of 5679 CAD patients from CORFCHD-PCI, a retrospective cohort study (identifier: ChiCTR-ORC-16010153), who underwent PCI were included in the study and divided into three tertiles according to their MHR values. The primary outcome was long-term mortality after PCI. The main secondary endpoints were stroke, readmission, and major adverse cardiovascular events (MACEs), defined as the combination of cardiac death, recurrent myocardial infarction, and target vessel reconstruction. The average follow-up time was 35.9 ± 22.6 months. RESULTS: Patients were divided into three groups according to MHR tertiles: the first tertile (MHR < 0.4; n=1290), second tertile (MHR ≥ 0.4-0.61; n=1878) and third tertile (MHR > 0.61; n=1870). The all-cause mortality (ACM) incidence was significantly lower in the first and second tertiles than in the third tertile (adjusted HR = 0.658, [95% CI: 0.408-0.903], P=0.009 and HR = 0.712, [95% CI: 0.538-0.941], P=0.017, respectively). Cardiac mortality (CM) occurred in 235 patients: 60 (3.1%) in the first tertile group, 74 (3.9%) in the second tertile group and 101 (5.4%) in the third tertile group. There was a significant difference in the CM incidence between the first tertile group and the third tertile group (HR = 0.581, [95% CI: 0.406-0.832], P=0.003), and there was also a difference in the CM incidence between the second tertile group and the third tertile group (HR = 0.690, [95% CI: 0.506-0.940], P=0.019). CONCLUSION: The present study indicated that an increased MHR was independently associated with long-term mortality in CAD patients who have undergone PCI.

UPLC-MS metabolomics method provides valuable insights into the effect and underlying mechanisms of Rhizoma Drynariae protecting osteoporosis.

Osteoporosis (OP) is a metabolic bone disease in which that volume of bone tissue per unit volume decrease, which is a common disease disturbing the elderly or postmenopausal women. Rhizoma Drynariae (RD) is a kind of herb widely used in thousands of years of clinical practice in China to tonify kidney and prevent osteoporosis, with reliable curative effect. However, the mechanism of its anti-osteoporosis action is still unclear. This study is dedicated to exploration the therapeutic effect of RD on retinoic acid solution-induced OP model rats based on high-throughput metabolomics technology platform, and reveal its influence on metabolomics level, so as to find effective potential biomarkers and therapeutic targets for diagnosing OP. OP model was established by intragastric administration of retinoic acid solution for 21 days, and then the treatment group was treated by intragastric administration of RD solution for 60 days. Blood samples of all groups were collected and analyzed based on UPLC-MS metabolomics and combined with EZinfo 3.0 data analysis, 32 potential biomarkers were identified, including 22 in ESI+ and 10 in ESI-, these biomarkers are related to 9 metabolic pathways. After treatment with RD solution, 21 biomarkers were obviously regulated, these mainly affected linoleic acid metabolic, glycerophospholipid metabolism and arachidonic acid metabolism pathway. The results show that RD can reduce the risk of OP disease, which may be related to the metabolic pathway mentioned above, and provides the foundation for the administer prophylaxis and treatment of OP with natural products.

The Fibrinogen-to-Albumin Ratio Is Associated With Outcomes in Patients With Coronary Artery Disease Who Underwent Percutaneous Coronary Intervention.

Coronary artery disease (CAD) is a systemic chronic inflammatory disease, and serum fibrinogen and albumin are 2 important factors in systemic inflammation. We aimed to investigate the relationship between the fibrinogen-albumin ratio (FAR) and outcomes in patients with CAD who underwent percutaneous coronary intervention (PCI). All patients were from the Clinical Outcomes and Risk Factors of Patients with Coronary Heart Disease after PCI (CORFCHD-PCI) study, which is a retrospective cohort study (Identifier: ChiCTR-ORC-16010153) that includes a total of 6050 patients with CAD after PCI from January 2008 to December 2016. A total of 5829 patients with CAD after PCI were recruited in the present study. They were divided into 2 groups according to the FAR cutoff value, which was calculated using a receiver operating characteristic curve, a low group (FAR < 0.095, n = 3811), and a high group (FAR ≥ 0.095, n = 2018). The average follow-up time was 35.9 ± 22.6 months. The multivariate Cox proportional hazards model showed that FAR was independently correlated with all-cause mortality (adjusted hazard ratio [HR] = 1.432 [1.134-1.808], P = .003), cardiac mortality (adjusted HR = 1.579 [1.218-2.047], P = .001), major adverse cardiac and cerebrovascular events (adjusted HR = 1.296 [1.125-1.494], P < .001), major adverse cardiac events (adjusted HR = 1.357 [1.170-1.572], P < .001), and heart failure (adjusted HR = 1.540 [1.135-2.091], P = .006). The present study indicated that the FAR was associated with adverse outcomes in patients with CAD who underwent PCI.

Effects of antidiabetic drugs on left ventricular function/dysfunction: a systematic review and network meta-analysis.

BACKGROUND: Although a variety of antidiabetic drugs have significant protective action on the cardiovascular system, it is still unclear which antidiabetic drugs can improve ventricular remodeling and fundamentally delay the process of heart failure. The purpose of this network meta-analysis is to compare the efficacy of sodium glucose cotransporter type 2 (SGLT-2) inhibitors, dipeptidyl peptidase-4 (DPP-4) inhibitors, glucagon-like peptide-1 (GLP-1) agonists, metformin (MET), sulfonylurea (SU) and thiazolidinediones (TZDs) in improving left ventricular (LV) remodeling in patients with type 2 diabetes (T2DM) and/or cardiovascular disease (CVD). METHODS: We searched articles published before October 18, 2019, regardless of language or data, in 4 electronic databases: PubMed, EMBASE, Cochrane Library and Web of Science. We included randomized controlled trials in this network meta-analysis, as well as a small number of cohort studies. The differences in the mean changes in left ventricular echocardiographic parameters between the treatment group and control group were evaluated. RESULTS: The difference in the mean change in LV ejection fraction (LVEF) between GLP-1 agonists and placebo in treatment effect was greater than zero (MD = 2.04% [0.64%, 3.43%]); similar results were observed for the difference in the mean change in LV end-diastolic diameter (LVEDD) between SGLT-2 inhibitors and placebo (MD = - 3.3 mm [5.31, - 5.29]), the difference in the mean change in LV end-systolic volume (LVESV) between GLP-1 agonists and placebo (MD = - 4.39 ml [- 8.09, - 0.7]); the difference in the mean change in E/e' between GLP-1 agonists and placebo (MD = - 1.05[- 1.78, - 0.32]); and the difference in the mean change in E/e' between SGLT-2 inhibitors and placebo (MD = - 1.91[- 3.39, - 0.43]). CONCLUSIONS: GLP-1 agonists are more significantly associated with improved LVEF, LVESV and E/e', SGLT-2 inhibitors are more significantly associated with improved LVEDD and E/e', and DPP-4 inhibitors are more strongly associated with a negative impact on LV end-diastolic volume (LVEDV) than are placebos. SGLT-2 inhibitors are superior to other drugs in pairwise comparisons.

Sodium tanshinone IIA sulfonate protects against Aß-induced cell toxicity through regulating Aß process.

Sodium tanshinone IIA sulfonate (STS) has been reported to prevent Alzheimer's disease (AD). However, the mechanism is still unknown. In this study, two in vitro models, Aß-treated SH-SY5Y cells and SH-SY5Y human neuroblastoma cells transfected with APPsw (SH-SY5Y-APPsw cells), were employed to investigate the neuroprotective of STS. The results revealed that pretreatment with STS (1, 10 and 100 µmol/L) for 24 hours could protect against Aß (10 µmol/L)-induced cell toxicity in a dose-dependent manner in the SH-SY5Y cells. Sodium tanshinone IIA sulfonate decreased the concentrations of reactive oxygen species, malondialdehyde, NO and iNOS, while increased the activities of superoxide dismutase and glutathione peroxidase in the SH-SY5Y cells. Sodium tanshinone IIA sulfonate decreased the levels of inflammatory factors (IL-1ß, IL-6 and TNF-α) in the SH-SY5Y cells. In addition, Western blot results revealed that the expressions of neprilysin and insulin-degrading enzyme were up-regulated in the SH-SY5Y cells after STS treatment. Furthermore, ELISA and Western blot results showed that STS could decrease the levels of Aß. ELISA and qPCR results indicated that STS could increase α-secretase (ADAM10) activity and decrease ß-secretase (BACE1) activity. In conclusion, STS could protect against Aß-induced cell damage by modulating Aß degration and generation. Sodium tanshinone IIA sulfonate could be a promising candidate for AD treatment.
