Comparative efficacy of various pharmacologic treatments for alcohol withdrawal syndrome: a systematic review and network meta-analysis.

This study was to compare multiple classes of medications and medication combinations to find alternatives or additives for patients not applicable to benzodiazepines (BZDs). We performed a network meta-analysis to assess the comparative effect of 11 pharmacologic treatments in patients with alcohol withdrawal syndrome. Forty-one studies were included, comprising a total sample size of 4187 participants. The pooled results from the randomized controlled trials showed that there was no significant difference in the Clinical Institute Withdrawal Assessment-Alcohol, revised (CIWA-Ar) reduction with other medications or medication combinations compared to BZDs. Compared to BZDs, the mean difference in ICU length of stay of anticonvulsants + BZDs was -1.71 days (95% CI = -2.82, -0.59). Efficacy rankings from cohort studies showed that anticonvulsant + BZDs were superior to other treatments in reducing CIWA-Ar scores and reducing the length of stay in the ICU. Synthesis results from randomized controlled trials indicate that there are currently no data suggesting that other medications or medication combinations can fully replace BZDs. However, synthetic results from observational studies have shown that BZDs are effective in the context of adjuvant anticonvulsant therapy, particularly with early use of gabapentin in combination with BZDs in the treatment of alcohol withdrawal syndrome, which represents a promising treatment option.

Risk Factors of Acute Pain in Elderly Patients After Laparoscopic Radical Resection of Colorectal Cancer.

OBJECTIVE: To investigate the risk factors of acute pain after laparoscopic radical resection of colorectal cancer (CRC) in elderly patients. METHODS: Totally, 143 elderly patients (≥ 60 y old) who received laparoscopic radical resection of CRC in the People's Hospital of Xinjiang Uygur Autonomous Region from March 2021 to August 2022 were retrospectively analyzed. The patients were divided into 2 groups according to visual analog scale (VAS) scores 24 h after surgery: mild pain group (VAS score ≤ 3, n=108) and moderate to severe pain group (VAS score >3, n=35). The data of the patients, including sex, age, height, body mass, intraoperative blood loss, intraoperative urine volume, intraoperative opioid dosage, operation duration, preoperative Hospital Anxiety and Depression Scale (HADS) scores, preoperative Mini-Mental State Examination scores, VAS scores, postoperative nausea and vomiting scores were recorded. Multivariate logistic regression analysis was used to screen the risk factors of postoperative acute pain in elderly patients undergoing laparoscopic radical resection of CRC. RESULTS: The preoperative HADS score of the moderate to severe pain group was significantly increased compared with that of the mild pain group (10.8±2.4 vs. 6.2±1.9), as well as the operation duration (226.4±18.3 vs. 186.1±12.7), the intraoperative dosage of remifentanil (3.7±0.2 vs. 3.2±0.4), the preoperative VAS score [4(2, 7) vs. 2 (0, 4)] and postoperative VAS score [5 (4, 6) vs. 3 (2, 3)] ( P <0.05). Multivariate logistic regression analysis showed that high preoperative HADS score, long operation duration, and high preoperative VAS score ( P <0.05) were independent risk factors for acute pain after laparoscopic radical resection of CRC in elderly patients. CONCLUSION: Preoperative anxiety and depression, preoperative pain, and long operation duration are risk factors for acute pain in elderly patients after laparoscopic radical resection of CRC.

Histone deacetylase 3 suppresses the expression of SHP-1 via deacetylation of DNMT1 to promote heart failure.

AIMS: Heart failure (HF) is a progressive disease with recurrent hospitalizations and high mortality. However, the mechanisms underlying HF remain unclear. The present study aimed to explore the regulatory mechanism of histone deacetylase 3 (HDAC3) and DNA methyltransferase 1 (DNMT1)/Src homology domain 2-containing tyrosine phosphatase-1 (SHP-1) axis in HF. METHODS: The HF rat models and hypertrophy cell models were established. The characteristic parameters of the heart were detected by echocardiography. A multichannel physiological signal acquisition system was used to detect the hemodynamic parameters. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression of HDAC3, DNMT1, and SHP-1 mRNAs, while Western blot was applied to analyze the expression of proteins. Masson staining was used to analyze the degree of collagen fiber infiltration. TdT-mediated DUTP nick end labeling (TUNEL) staining was performed to analyze the apoptosis of myocardial tissue cells. Co-immunoprecipitation (co-IP) was conducted to study the interaction between HDAC3 and DNMT1. Flow cytometry was used to analyze the apoptosis. KEY FINDINGS: HDAC3 and DNMT1 were highly expressed in HF rat and hypertrophy cell models. HDAC3 modified DNMT1 through deacetylation to inhibit ubiquitination-mediated degradation, which promoted the expression of DNMT1. DNMT1 inhibited SHP-1 expression via methylation in the promoter region. In summary, HDAC3 modified DNMT1 by deacetylation to suppress SHP-1 expression, which in turn led to the development of cardiomyocyte hypertrophy-induced HF. SIGNIFICANCE: This study provided potential therapeutic targets for HF treatment.

Challenges of patients with epilepsy and measures for improving epilepsy care in western China: A qualitative study.

OBJECTIVE: The aim of this qualitative study was to explore the challenges that patients with epilepsy (PWEs) face and the opportunities or areas where changes in nursing care may improve epilepsy care in western China. METHODS: Semi-structured interviews with open-ended questions based on a review of the literature were conducted at the epilepsy center of a tertiary hospital in western China. A total of 18 PWEs, 18 caregivers and 11 neurology nurses were interviewed by using purposive sampling. The data were transcribed verbatim, and a content analysis was used to conduct the framework analysis. RESULTS: Three key themes were identified, namely, the impact of epilepsy, barriers to epilepsy management, and measures in nursing care for improving epilepsy care. Psychological stress, the side effects of drugs and accidental injury related to seizures were reported to be the main negative impacts on patients. Limited knowledge about epilepsy, poor adherence to therapy, and a lack of effective communication between patients and medical staff were the major barriers to epilepsy management. Strengthening health education, assessing the frequency and type of seizures, screening for psychological disorders and mental intervention, and maintaining continuity of care were identified as crucial measures for nurses to improve epilepsy care. CONCLUSIONS: This study highlights the challenges among PWEs and opportunities for improving the quality of epilepsy care in western China. Limited knowledge and poor drug adherence are the main barriers to epilepsy management, which might be improved by more health education and continuing care provided by nurses. Assessing seizures, screening for psychological disorders and providing appropriate psychological care would help improve epilepsy care.

Direct economic burden of patients with tuberculous meningitis in western China.

OBJECTIVE: To estimate the direct economic burden of tuberculous meningitis (TBM) in China for the first time. METHODS: Patients who were first diagnosed with TBM from December 2015 to December 2018 in Western China Hospital were enrolled. We retrospectively collected data on demographic and clinical features, resource utilization, costs, and long-term outcomes. The patients were followed up for 15-53 months. We performed a cost-of-illness study and analyzed the cost contributors with a generalized linear model. RESULTS: In total, the cases of 154 TBM patients (95 males, 59 females, aged 14-82 years) were reviewed. The average total direct cost per person was USD (United States dollars) 9,484 (range 1,822-67,285), with a mean direct medical cost of USD 8,901 (range 1,189-67,049). The average inpatient cost and drug cost after discharge were USD 6,837 (range 845-52,921) and USD 1,967 (range 0-60,423), respectively. The mean direct nonmedical cost was USD 583 (range 33-3,817), which accounted for 6.2% of the total direct cost. The average length of stay (LOS) in hospital was 25.0 days (range 6-152). A total of 117 of the patients (76.0%) had good outcomes (mRS = 0-2). There was no significant difference in the costs, LOS, or outcomes between rural and urban patients. Contributors to total direct cost were definite TBM, fever, coma, seizures, multidrug resistance, hydrocephalus, and poor long-term outcome. CONCLUSIONS: Although the accessibility of medical resources in remote and rural regions has significantly improved in China, the cost of TBM imposes a catastrophic burden on patients.

Identification of prognosis-associated immune genes and exploration of immune cell infiltration in colorectal cancer.

Aim: To identify prognosis-related immune genes (PRIGs) and construct a prognosis model of colorectal cancer (CRC) patients for clinical use. Materials & methods: Expression profiles were obtained from The Cancer Genome Atlas database and identified differentially expressed PRIGs of CRC. Results: A prognostic model was conducted based on nine PRIGs. The risk score, based on prognosis model, was an independent prognostic predictor. Five PRIGs and risk score were significantly associated with the clinical stage of CRC and five immune cells related to the risk score. Conclusion: The risk score was an independent prognostic biomarker for CRC patients. The research excavated immune genes that were associated with survival and that could be potential biomarkers for prognosis and treatment for CRC patients.

A systematic review of etiology, epidemiology, clinical manifestations, image findings, and medication of 2019 Corona Virus Disease-19 in Wuhan, China.

BACKGROUND: Unknown origin pneumonia has been furiously spreading since the late of December 2019, subsequently spread to approximately all provinces and areas in China and many countries, which was announced as a Public Health Emergency of International Concern by World Health Organization (WHO). The studies on 2019 Corona Virus Disease-19 (COVID-19) conducted from various fields around the world. Herein, the objective of the present study is to summarize the etiology, epidemiology, clinical manifestations, image findings, traceability analysis, and drug development of COVID-19. METHODS: The following electronic databases were searched: Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database, VIP Chinese Science and Technology Periodical Database, and Wanfang Data. Other relevant literature will be manually searched as a compliment. We have reviewed etiology, epidemiology, clinical manifestations, image findings, and medication from case reports and retrospective clinical studies relating to COVID-19 published since the outbreak. RESULTS: The coronavirus is closely related to bat coronavirus and pangolin coronavirus. Besides, the infection pathway is confirmed to be the respiratory and digestive systems. The virus indicates person-to-person transmission and some patients present asymptomatic. The elderly have a higher mortality rate. Rapid and sensitive nucleic acid testing is usually used as a basis for diagnosis. Currently, there is no specific vaccine and antiviral drug. Intervention actions such as travel bans and quarantine adopted have effectively reduced the spread of the epidemic. CONCLUSION: This systemic review will provide high-quality evidence to summarize etiology, epidemiology, clinical manifestations, image findings, traceability analysis, drug development in patients with COVID-19.

New molecular diagnostic technologies for clinical detection of SARS-CoV-2.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused an ongoing pandemic of new coronavirus pneumonia (corona virus disease 2019, COVID-19). The virus has a long incubation period and strong infectivity, which poses a major threat to global health and safety. Detection of SARS-CoV-2 nucleic acid lies at the center of rapid detection of COVID-19, which is instrumental for mitigation of the ongoing pandemic. As of August 17, 2020, The National Medical Products Administration in China has approved 15 new coronavirus nucleic acid detection kits, 10 kits of which are based on reverse transcription-real-time quantitative PCR (RT-qPCR) technology. The remaining kits use five molecular diagnostic technologies different from RT-qPCR. This article reviews the principles, reaction time, advantages and disadvantages of above 15 detection kits, in order to provide references for rapid screening, diagnosis, prevention and control of COVID-19 and similar infectious diseases.

Correlations Between mRNA Levels of Centrosomal Protein 55 (CEP55) and Clinical Features of Patients with Lung Cancer.

BACKGROUND The aim of this study was to investigate the prognostic relevance of CEP55 in lung cancer (LC). MATERIAL AND METHODS LC microarray profile GSE30219 was obtained from the GEO database. The 2-sample t test was performed to clarify the difference in CEP55 expression between LC and normal lung tissue. The chi-square test and logistic regression analysis were preformed to investigate the relationship between CEP55 expression and the clinical features of LC patients. Log-rank test and Cox proportional hazards regression analysis were conducted to evaluate the disease-free survival (DFS) and overall survival (OS) of LC patients. Gene set enrichment analysis was conducted to investigate the related mechanisms. RESULTS CEP55 was significantly increased in LC cells relative to normal lung tissues (P<0.0001). Univariate and multivariate correlation analyses demonstrated that CEP55 expression was associated with advanced T and N staging of LC (P<0.0001). Survival analyses indicated that CEP55 expression was an independent risk factor for DFS (HR: 1.515, 95% CI: 1.277-1.797, P<0.0001) and OS (HR: 1.436, 95% CI: 1.278-1.615). CEP55 might affect the proliferation of LC cells through Myc signaling, DNA repair, and G2M checkpoint. CONCLUSIONS Our results indicated that CEP55 was increased in LC cells and was associated with poor clinical outcomes of LC patients, and could be a prognostic biomarker for LC.

Vasorelaxant effects of the extracts and some flavonoids from the buds of Coreopsis tinctoria.

CONTEXT: The buds of Coreopsis tinctoria Nutt (Compositae) are used in the treatment of hypertension in the Uyghur folk medicine in China. OBJECTIVE: To investigate vasorelaxant properties of extracts and some flavonoids from C. tinctoria (CT) and their underlying mechanisms in isolated rat thoracic aortic rings. MATERIALS AND METHODS: Vasorelaxant effects of ethanol extracts of CT (CTA) and its flavonoids as well as water-ethanol eluates from CTA by AB-8 resins (CTAA∼CTAF) were evaluated on rat aortic rings pre-contracted with phenylephrine (PE, 1 µM) or high KCl (60 µM). We evaluated the effect of CTA, CTAD and CTAE on PE-induced contraction in a Ca²âº-free medium and a dose-effect curve of Ca²âº in pre-contracted ring with high KCl. RESULTS: Endothelial removal did not modify the effect of CTAD and CTAE (3.00 g/L) neither on PE-pre-contracted rings (164.78 ± 21.44 and 191.47 ± 16.75%) nor on KCl-pre-contracted rings (75.68 ± 10.76 and 125.14 ± 17.41%) compared with intact-endothelium rings pre-contracted with high KCl (100.49 ± 17.30 and 110.81 ± 16.33%). CTAD and CTAE (3.00 g/L) down-regulated the dose-effect curve of Ca²âº in pre-contraction with high KCl, and inhibited the pre-contraction with PE in a Ca²âº-free medium (p < 0.05). Seven flavonoids were obtained from CTAD, of which luteolin (5) and quercetin (6) were found to be the most effective relaxation in rings precontracted with PE (EC50: 0.006 and 0.039 g/L, p < 0.05) or high KCl (EC50: 0.023 and 0.045 g/L, p < 0.05). DISCUSSION AND CONCLUSION: These data demonstrated the vasorelaxant effect of CT, and its mechanism is likely due to an inhibitory effect on calcium movements through cell membranes.
