OBJECTIVE To explore the independent risk factors of voriconazole （VCZ）-related liver injury in elderly patients with hypoproteinemia. METHODS Elderly patients with invasive fungal infection and hypoproteinemia who were hospitalized in the respiratory intensive care unit of our hospital and treated with VCZ from August 2020 to July 2023 were selected. They were divided into group A （liver injury group） and group B （non-liver injury group） based on whether the liver injury occurred after using VCZ. Pearson correlation analysis was used to analyze the correlation between minimum concentration （cmin） of VCZ and inflammatory factor[C-reactive protein （CRP）， procalcitonin （PCT）， interleukin-6 （IL-6）]， as well as liver function [alanine transaminase （ALT）， aspartate transaminase （AST）， alkaline phosphatase （ALP）， gamma-glutamyl transpeptidase （GGT）， total bilirubin （TBIL）]； univariate analysis was performed by using χ 2 test； Logistic regression analysis was used to analyze the independent risk factors affecting the occurrence of liver injury. RESULTS A total of 320 patients were included in the study， of whom 56 developed liver injury， with an incidence of 17.50%. The VCZ cmin in group A was significantly higher than group B （P＝ 0.021）. CRP， PCT， IL-6， and TBIL were correlated with VCZ cmin （P＜0.05）. CRP， PCT， IL-6， and TBIL had a significant impact on VCZ cmin （P＜0.05）. VCZ cmin， PCT， and TBIL were independent risk factors for liver injury （P＜0.05）. The patients with VCZ cmin≥3.76 mg/L had a significantly increased risk of liver injury. CONCLUSIONS VCZ cmin， PCT， and TBIL are independent risk factors for the occurrence of liver injury in elderly patients with hypoproteinemia. For patients with high PCT and TBIL， VCZ cmin and liver function should be closely monitored during VCZ treatment to reduce the risk of liver injury.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Objective:To investigate the effects of low-dose ropivacaine combined with sufentanil on the onset time of anesthesia and postoperative rectal traction reflectance in patients undergoing mixed hemorrhoid surgery.Methods:A total of 96 patients who underwent mixed hemorrhoid surgery at the General Hospital of the Southern Theater Command of the Chinese People′s Liberation Army from January 2020 to June 2021 were selected. They were randomly divided into a control group and an observation group using a random number table method, with 48 cases in each group. The control group was anesthetized with low-dose ropivacaine; The observation group was anesthetized with low-dose ropivacaine combined with sufentanil. The anesthesia effect, hemodynamic changes, pain score, bleeding score, postoperative rectal traction reflectance, and incidence of adverse reactions were compared between two groups of patients.Results:Compared with the control group, the observation group had a shorter onset time of anesthesia ( P<0.05) and a longer duration of anesthesia maintenance ( P<0.05). Before surgery, there was no statistically significant difference in heart rate and mean arterial pressure between the two groups of mixed hemorrhoid patients (all P>0.05); After surgery, both groups of patients had an increase in heart rate, a decrease in mean arterial pressure, and a more significant change in the control group (all P<0.05). Before surgery, there was no statistically significant difference in Visual Analogue Scale (VAS) scores and bleeding scores between the two groups of mixed hemorrhoid surgery patients (all P>0.05); After 1 day of surgery, the VAS score and bleeding score of both groups of patients were significantly reduced (all P<0.05), and the observation group showed a more significant decrease (all P<0.05). The postoperative recovery rate of anal contraction in the observation group was higher than that in the control group ( P<0.05), and the rectal traction reflectance was lower than that in the control group ( P<0.05). The total incidence of adverse reactions in the observation group was significantly lower than that in the control group (χ 2=4.667, P<0.05). Conclusions:The combination of low-dose ropivacaine and sufentanil has a definite anesthetic effect on patients undergoing mixed hemorrhoid surgery. It can improve the onset time of anesthesia and postoperative rectal traction reflectivity, alleviate patient pain, and has high safety.

Objectives: . Considerable research has been focused on independent predictors of difficult laryngeal exposure (DLE) during suspension laryngoscopy. However, previous studies have yielded inconsistent results and conclusions. Consequently, we performed a meta-analysis of the existing literature with the aim of identifying significant parameters for a standardized preoperative DLE prediction system. Methods: . We systematically retrieved articles from the PubMed, Embase, Web of Science, China National Knowledge Infrastructure, and Wanfang databases up to October 2022. Data from eligible studies were extracted and analyzed using the R programming language. The effect measures included odds ratios (ORs) with 95% confidence intervals (CIs) for dichotomous variables and mean differences (MDs) with 95% CIs for continuous variables. Results: . The search yielded 1,574 studies, of which 18 (involving a total of 2,263 patients) were included. Pooled analysis demonstrated that patients with DLE during microsurgery tended to be male (OR, 1.73; 95% CI, 1.16–2.57); were older (MD, 5.47 years, 95% CI, 2.44–8.51 years); had a higher body mass index (BMI; MD, 1.19 kg/m2; 95% CI, 0.33–2.05 kg/m2); had a greater neck circumference (MD, 2.50 cm; 95% CI, 1.56–3.44 cm); exhibited limited mouth opening (MD, −0.52 cm; 95% CI, −0.88 to −0.15 cm); had limited neck flexibility (MD, −10.05 cm; 95% CI, −14.10 to −6.00 cm); displayed various other anatomical characteristics; and had a high modified Mallampati index (MMI) or test score (OR, 3.37; 95% CI, 2.07–5.48). Conclusion . We conducted a comprehensive and systematic analysis of the factors relevant to DLE. Ultimately, we identified sex, age, BMI, neck circumference, MMI, inter-incisor gap, hyomental distance, thyromental distance, sternomental distance, and flexion-extension angle as factors highly correlated with DLE.

Guillain-Barré syndrome (GBS) defines a kind of Immune-mediated acute inflammatory peripheral neuropathy. Miller-Fisher Syndrome (MFS) is a special variant of GBS, with mostly one-way course and rare clinical recurrence. Only a few recurrent cases have been reported in China. Here we report a case of a young male patient with double vision and progressive aggravation of limb numbness, acute onset, with symptoms of upper respiratory tract infection before onset, accompanied by pupil abnormalities and autonomic nervous dysfunction, who was was admitted to our hospital for similar symptoms 3 years ago and was improved by immunotherapy. The patient had a triad of “ataxia, areflexia and ophthalmoplegia”. Cerebrospinal fluid showed protein-cell separation. Serum anti-Sulfatides antibody IgM, anti-GT1a antibody IgG, anti-GQ1b antibody IgG and anti-GM3 IgM were positive. Recurrent MFS was diagnosed and the symptoms improved after immunotherapy. This case suggests that MFS is clinically heterogeneous, a few patients can present with relapse and generally have a better prognosis with immunotherapy. Pre-existing infection and anti-GQ1b antibody production may be predisposing factors for MFS recurrence.

OBJECTIVE To systematically evaluate the efficacy and safety of vonoprazan （VPZ） for Helicobacter pylori （Hp） eradication therapy. METHODS Retrieved from The Cochrane Library， Embase， PubMed， CNKI， VIP and Wanfang database， randomized controlled trials about VPZ for Hp eradication therapy （trial group） versus proton pump inhibitor （PPI） （control group） were collected during the inception to July 2022. After data extraction and quality evaluation with bias risk assessment tool recommended by Cochrane System Evaluation Manual 5.1.0， meta-analysis was performed by using RevMan5.3 software. RESULTS Nine studies with 2 134 patients were included. Compared with control group， the overall Hp eradication rate of trial group increased significantly in either the ITT analysis or PP analysis， being 87.5% vs. 76.2% [RR＝1.14， 95%CI （1.06，1.21）， P＜0.001] and 92.4% vs. 80.5% [RR＝1.11， 95%CI （1.03，1.21）， P＜0.01]， respectively. According to ITT and PP analysis of primary treatment subgroup， compared with control group， the overall Hp eradication rate of trial group increased significantly， being 88.4% vs. 76.5% [RR＝1.15， 95%CI （1.09，1.22）， P＜0.000 01] and 92.8% vs. 80.9% [RR＝1.12， 95%CI（1.03，1.23）， P＜ 0.05]； according to ITT and PP analysis of rescue therapy subgroup， there was no significant difference in the overall Hp eradication rate between control group and trial group （P＞0.05）. According to ITT and PP analysis of triple therapy subgroup， compared with control group， overall Hp eradication rate of trial group increased significantly， being 88.3% vs. 75.6% [RR＝1.16， 95%CI （1.08， 1.25）， P＜0.000 1] and 92.6% vs. 77.6% [RR=1.15， 95%CI （1.04， 1.28）， P＜0.01]； according to ITT and PP analysis of quadruple therapy subgroup， there was no significant difference in the overall Hp eradication rate between control group and trial group （P＞0.05）. Compared with control group， the incidence of adverse events in trial group decreased significantly， being 34.2% vs. 40.9% [RR＝0.84， 95%CI（0.70，0.99）， P＜ 0.05]. There was no statistical significance in the incidence of serious adverse events between 2 groups （P＞0.05）. CONCLUSIONS Compared with PPI therapy， the efficacy of VPZ-based triple therapy is better， particularly in primary treatment patients. However， VPZ has no significant advantage in rescue treatment and bismuth-containing quadruple regimen. And the safety and tolerance of VPZ for Hp eradication therapy are well， even better than PPI.

Immunothrombosis refers to the innate immune response caused by thrombosis in blood vessels(especially microvessels).Immunothrombosis is related to immune cells and specific thrombosis related molecules,producing intravascular scaffolds that promote pathogen recognition,inhibition,and destruction,thereby protecting the integrity of the host.However,abnormal or uncontrolled activation of immunothrombosis may be harmful to the host and serve as the foundation for various infectious and inflammatory related thrombotic diseases.Therefore,understanding the potential mechanisms of immunothrombosis plays a decisive role in developing more effective therapies for thrombosis treatment and prevention.This review provides an overview of the mechanisms of immunothrombosis in order to understand new treatment strategies for reducing the risk of immunothrombosis.

Background Lipid metabolism in liver shows circadian-dependent profiles. The hepatotoxicity of environmental chemicals is dependent on circadian time. Objective To observe the effects of bisphenol A (BPA) exposure at different zeitgeber time (ZT) on hepatic and blood lipid metabolism and decipher the underlying mechanisms related to circadian rhythm in mice. Methods Thirty-five female C57BL/6J mice were sacrificed every 4 h in a light-dark cycle (12 h/12 h). The liver tissues were collected to describe the circadian profiles of hepatic Rev-erba, Bmal1, Clock, Srebp1c, and Chrebp mRNA expression levels within 24 h. Thirty female mice were divided into 6 groups by the timing (ZT3 represents the 3 h after light on, ZT15 represents the 3 h after light off) and dose (50 or 500 μg·kg⁻¹·d⁻¹) of BPA exposure to observe hepatotoxicity. Mice were gavaged with designed doses of BPA once per day for 4 weeks. Mice were maintained with ad libitum access to food and water and measured body weight weekly. After the experiment, mice were euthanatized and liver tissues were separated to determine the biochemical indicators of lipid metabolism and lipid metabolism- and circadian-related gene mRNA expressions. Results Hepatic Rev-erba, Bmal1, Clock, Srebp1c, and Chrebp mRNA expression levels were rhythmic during a 24 h period in mice. At ZT3 and ZT15, BPA did not alter body weight, plasma glucose, plasma total cholesterol, plasma low density lipoprotein cholesterol, and plasma triglycerides (P>0.05). The plasma high density lipoprotein cholesterol decreased in the 50 μg·kg⁻¹·d⁻¹ BPA group at ZT3 by 14.56% compared with the control group (P<0.05). The liver triglycerides increased in the 50 μg·kg⁻¹·d⁻¹ BPA group at ZT15 by 115.20% compared with the control group (P<0.05). BPA decreased Srebp1c mRNA expression level when dosing at ZT3 and increased Chrebp, Srebp1c, and Acc1 mRNA expression levels when dosing at ZT15 compared with the control group (P<0.05). BPA increased Bmal1 mRNA expression level and decreased Rev-erbα mRNA expression level at ZT3 exposure and decreased Bmal1 and increased Rev-erbα mRNA expression level at ZT15 exposure (P<0.05). Conclusion BPA exposure at light or dark period has different effects on hepatic lipid metabolism in mice. Hepatic lipid deposit appears when BPA is dosed at dark period. Rev-erbα-Bmal1 regulation circuits and the subsequent upregulation of Srebp1c and Chrebp and the target gene Acc1 may be involved.

Objective:To explore the impact of hypophosphatemia on the occurrence and prognosis of critically ill patient.Methods:The clinical data of critically ill patients admitted to the intensive care unit (ICU) of Tianjin First Central Hospital from October 2021 to April 2022 were retrospectively analyzed. Patients were divided into hypophosphatemia group (serum phosphorus level < 0.80 mmol/L) and non-hypophosphatemia group (serum phosphorus level ≥ 0.80 mmol/L) when they were admitted to the ICU. The following variables were also collected, including gender, age, acute physiology and chronic health evaluationⅡ(APACHE Ⅱ), sequential organ failure assessment (SOFA), serum phosphorus level, serum calcium level, serum magnesium level, white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), neutrophil/lymphocyte ratio (NLR), C-reactive protein (CRP), presence of infection and infection site, length of hospital stay, ICU stay, 28-day mortality, and mechanical ventilation time. Multivariate Logistic regression analysis was used to evaluate the relationship between each variable and the 28-day mortality. The receiver operator characteristic curve (ROC curve) was drawn, and the area under the ROC curve (AUC) and 95% confidence interval (95% CI) were calculated to evaluate the predictive value of serum phosphorus levels for the prognosis of ICU patients. Results:A total of 263 patients were enrolled, including 54 patients with hypophosphatemia and 209 patients without. The SOFA score, LYM level and the infection rate of patients in the hypophosphatemia group were significantly higher than those in the non-hypophosphatemia group [SOFA score: 6.70±3.17 vs. 5.64±3.59, LYM (×10 9/L): 0.99±0.54 vs. 0.77±0.54, infection rate: 77.78% (42/54) vs. 59.33% (124/209), all P < 0.05], the NLR was significantly lower than that of the non-hypophosphatemia group [10.67 (7.08, 18.02) vs. 12.25 (7.25, 21.68), P < 0.05]. The length of hospital stay, ICU stay, and mechanical ventilation duration in the hypophosphatemia group were significantly longer than those in the non-hypophosphatemia group [length of hospital stay (days): 15 (11, 28) vs. 12 (6, 21), length of ICU stay (days): 10.35±7.80 vs 7.15±6.61, mechanical ventilation duration (days): 3 (0, 12) vs. 2 (0, 5), all P < 0.05]. There was no significant difference in the 28-day mortality between the hypophosphatemia group and the non-hypophosphatemia group [9.26% (5/54) vs. 11.00% (23/209), P > 0.05]. Multivariate Logistic regression analysis showed that APACHE Ⅱ score [odds ratio ( OR) = 1.188, 95% CI was 1.110-1.271], CRP ( OR = 1.016, 95% CI was 1.007-1.026), and NLR ( OR = 1.002, 95% CI was 0.996-1.008) were independent risk factors affecting the 28-day mortality of critically ill patients in ICU (all P < 0.05). ROC curve analysis showed that the AUC of serum phosphorus levels for predicting the length of hospital stay of critically ill patients in ICU > 10 days, ICU stay > 5 days, and mechanical ventilation duration > 5 days were 0.701 (95% CI was 0.632-0.770), 0.771 (95% CI was 0.691-0.852), 0.617 (95% CI was 0.541-0.692), respectively, all P < 0.01. Conclusion:Hypophosphatemia has some predictive value for the length of hospital and ICU stay and mechanical ventilation time in critically ill patients, but it cannot predict the 28-day mortality.
