Abstract
Background Talaromycosis is a serious opportunistic infectious disease caused by Talaromyces marneffei, which mostly occurs in immunocompromised patients. The disease is mainly prevalent in tropical countries and regions of Southeast Asia and South Asia, but non-endemic areas also have patients with Talaromycosis. The disease has no characteristic clinical manifestations and is difficult to diagnose. Delayed diagnosis often leads to death. Case presentation Both patients had cellular immunodeficiency. Case 1 had a history of acquired immune deficiency syndrome, and case 2 had a history of renal transplantation and glucose-6-phosphate dehydrogenase deficiency. They all had fever, anemia, fatigue, and skin lesions. Case 1 had gastrointestinal bleeding, enlarged lymph nodes, and hepatosplenomegaly. Case 2 had cough and dyspnea. Both patients had thrombocytopenia and hypoalbuminemia; an increased neutrophil ratio, procalcitonin, and C-reactive protein; and abnormal liver function and coagulation dysfunction. Case 1 sputum culture, blood culture, and bronchoalveolar lavage fluid were positive for T. marneffei. T. marneffei was detected in the blood culture of case 2, with infection of Candida parapsilosis and Pneumocystis jirovecii. Chest computed tomography scan mainly showed pulmonary exudative lesions. Although these two patients were actively treated, they died of poor efficacy. Conclusion Talaromycosis has an insidious onset, long course, atypical clinical symptoms, imaging performance and laboratory results, difficult diagnosis, and high mortality. Therefore, it is important to promptly consider and treat Talaromycosis in immunocompromised patients upon infection in order to reduce mortality.

Abstract
Sepsis-induced cardiomyopathy (SIC) is characterized by high mortality and poor outcomes. This study aimed to explore the relationship between testosterone and soluble ST2 (sST2) and all-cause mortality in patients with SIC. Clinical data from SIC patients at Renmin Hospital of Wuhan University from January 2021 and March 2023 were reviewed. Serum testosterone and sST2 were measured at admission. Kaplan-Meier analysis and receiver operative characteristic curve (ROC) were used to estimate the predictive values of testosterone and sST2 on 28 days and 90 days mortality of SIC. A total of 327 male subjects with SIC were enrolled in this study. During the 28 days and 90 days follow-up, 87 (26.6%) and 103 deaths (31.5%) occurred, respectively. Kaplan-Meier analysis showed significantly higher 28 days and 90 days survival in patients with higher testosterone and decreased sST2 levels (p < 0.001). Testosterone, sST2, and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were significantly associated with 28 days and 90 days mortality (p < 0.05). Partial correlation analysis showed strong positive correlation between testosterone and left ventricular ejection fraction (LVEF) (p < 0.001), and negative correlation between testosterone and sST2 (p < 0.001), high-sensitivity troponin I (hs-TnI) levels (p < 0.001) and smoke history (p < 0.01). The concentrations of sST2 were positively related with E/e' ratio (p < 0.001), and negatively correlated with TAPSE (p < 0.001). The combination of testosterone and sST2 enhanced the prediction of both 28 days [area under the ROC curve (AUC), 0.805] and 90 days mortality (AUC, 0.833). Early serum testosterone and sST2 levels could predict mortality of SIC independently and jointly. Further research is needed to determine the utility of biochemical markers in identifying high-risk patients with SIC.

Abstract
OBJECTIVE This study compared remimazolam tosylate with propofol or midazolam to assess its safety and effectiveness for long-term sedation of intensive care unit (ICU) patients requiring mechanical ventilation. METHODS Adult patients in the ICU receiving sedation and mechanical ventilation for longer than 24 h were included in this single-center, prospective, observational study. Depending on the sedatives they were given, they were split into two groups (midazolam or propofol group; remimazolam group). ICU mortality was the main result. Laboratory tests, adverse events, and the length of ICU stay were considered secondary outcomes. RESULTS A total of 106 patients were involved (46 received propofol or midazolam versus 60 received remimazolam). Age (P = 0.182), gender (P = 0.325), and the amount of time between being admitted to the ICU and receiving medication infusion (P = 0.770) did not substantially differ between the two groups. Multivariate analysis revealed no statistically significant difference in ICU mortality between the two groups. The remimazolam group showed less variability in heart rate (P = 0.0021), pH (P = 0.048), bicarbonate (P = 0.0133), lactate (P = 0.0002), arterial blood gas analyses, liver, and kidney function. The Richmond Agitation and Sedation Scale scores, length of ICU stay, and occurrence of adverse events did not exhibit significant differences between the two groups. CONCLUSION Remimazolam tosylate did not increase the total inpatient cost, the incidence of adverse events, and ICU mortality in patients with mechanical ventilation. These findings suggest that remimazolam may represent a promising alternative for sedation in the ICU setting.

Abstract
OBJECTIVES Teaching clinical skills is an important component of educational programmes for medical undergraduates. However, the extension of the interval between the completion of the course and qualification examination affects the performance of students in the skill examination. This study established a multisource evaluation system to determine whether formative assessment can enhance the instruction of clinical skills. METHODS Formative assessment was introduced to the entire training course on clinical skills, in which diversified methods were used to observe the performance of students during training. Students in the experimental group received training for clinical skills using formative assessment (class of 2019, n=128), while students in the control group received traditional training without formative assessment (class of 2018, n=123). Both groups participated in the Objective Structured Clinical Examination (OSCE) conducted by Tongji Medical College, and the exam scores were taken as the objective measure of course outcome. After completing the course, all students in the experimental group were instructed to fill in a questionnaire to evaluate their experience in the training programme, as a subjective measure of course outcome. RESULTS Compared with the control group, students in the experimental group received significantly better practical scores in the four clinical skills tested by the OSCE. The questionnaire results revealed that the majority of students who were trained using formative assessment methods considered the course helpful for learning, and appreciated the course for the clinical skills they had gained, and the opportunity to receive and give feedback to the instructors. CONCLUSIONS The findings of this study suggest that formative assessment methods are beneficial for learning clinical skills through simulated teaching, as shown by the improved objective clinical skills evaluated by the structured clinical examination, and the self-reported satisfaction with the learning process.

Abstract
Background Nanopore Target Sequencing (NTS) represents a novel iteration of gene sequencing technology; however, its potential utility in the detection of infection in deceased donors has yet to be documented. The present study endeavors to assess the applicability of NTS in this domain. Methods This retrospective study comprised a cohort of 71 patients who were under intensive care at Renmin Hospital of Wuhan University between June 2020 and January 2022. The specimens were subjected to microbiological tests utilizing NTS, culture, and other techniques, and subsequently, the diagnostic accuracy of NTS was compared with conventional methods. Results Blood NTS exhibited a better agreement rate of 52.11% and a greater positive rate of pathogen detection than blood culture (50.70% vs. 5.63%, p < 0.001). In NTS of deceased donors, Klebsiella pneumoniae, Escherichia coli, and Acinetobacter baumannii were the most frequently found bacteria, and Candida was the most frequently found fungus. Blood NTS had a considerably better sensitivity for detecting clinical bloodstream infection than blood culture (62.50%: 7.14%, p < 0.001). These findings were supported by comparisons between blood NTS and conventional microbial detection methods (such as blood culture, glucan testing, galactomannan testing, T cell spot testing for tuberculosis infection, smear, etc.). Conclusion The pathogen detection technology NTS has a high sensitivity and positive rate. It can more accurately and earlier detect infection in deceased donors, which could be very important for raising the donation conversion rate.

Abstract
BACKGROUND Sepsis-induced acute lung injury (ALI) is associated with poor survival rates. The identification of potential therapeutic targets for preventing sepsis-induced ALI has clinical importance. This study aims to investigate the role of estrogen-related receptor alpha (ERRα) in sepsis-induced ALI. METHODS Lipopolysaccharide (LPS) was used to simulate sepsis-induced ALI model in rat pulmonary microvascular endothelial cells (PMVECs). The effects of ERRα overexpression and knockdown on LPS-induced endothelial permeability, apoptosis and autophagy were determined by horseradish peroxidase permeability assay, TdT-mediated dUTP Nick End Labeling (TUNEL) assay, flow cytometry, immunofluorescence staining, RT-PCR and Western Blotting. The rat model with sepsis-induced ALI was established by cecal ligation and puncture in anesthetized rats to verify the results of in vitro experiments. Animals were randomly assigned to receive intraperitoneal injection of vehicle or ERRα agonist. Lung vascular permeability, pathological injury, apoptosis and autophagy were examined. RESULTS Overexpression of ERRα ameliorated LPS-induced endothelial hyperpermeability, degradation of adherens junctional molecules, upregulation of bax, cleaved caspase 3 and cleaved caspase 9 levels, downregulation of anti-apoptotic protein Bcl-2 level, and promoted the formation of autophagic flux, while the knockdown of ERRα exacerbated LPS-induced apoptosis and inhibited the activation of autophagy. Administration of ERRα agonist alleviated the pathological damage of lung tissue, increased the levels of tight junction proteins and adherens junction proteins, and decreased the expression of apoptosis-related proteins. Promoting the expression of ERRα significantly enhanced the process of autophagy and reduced CLP-induced ALI. Mechanistically, ERRα is essential to regulate the balance between autophagy and apoptosis to maintain the adherens junctional integrity. CONCLUSION ERRα protects against sepsis-induced ALI through ERRα-mediated apoptosis and autophagy. Activation of ERRα provides a new therapeutic opportunity to prevent sepsis-induced ALI.

Abstract
INTRODUCTION Albuminuria, or elevated urinary albumin-to-creatine ratio (UACR), is a biomarker for chronic kidney disease that is routinely monitored in patients with type 2 diabetes (T2D). Head-to-head comparisons of novel antidiabetic drugs on albuminuria outcomes remain limited. This systematic review qualitatively compared the efficacy of novel antidiabetic drugs on improving albuminuria outcomes in patients with T2D. METHODS We searched the MEDLINE database until December 2022 for Phase 3 or 4 randomized, placebo-controlled trials that evaluated the effects of sodium-glucose co-transporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and dipeptidyl peptidase-4 (DPP-4) inhibitors on changes in UACR and albuminuria categories in patients with T2D. RESULTS Among 211 records identified, 27 were included, which reported on 16 trials. SGLT2 inhibitors and GLP-1 RAs decreased UACR by 19-22% and 17-33%, respectively, versus placebo (P < 0.05 for all studies) over median follow-up of ≥ 2 years; DPP-4 inhibitors showed varying effects on UACR. Compared with placebo, SGLT2 inhibitors decreased the risk for albuminuria onset by 16-20% and for albuminuria progression by 27-48% (P < 0.05 for all studies) and promoted albuminuria regression (P < 0.05 for all studies) over median follow-up of ≥ 2 years. Evidence on changes in albuminuria categories with GLP-1 RA or DPP-4 inhibitor treatment were limited with varying outcome definitions across studies and potential drug-specific effects within each class. The effect of novel antidiabetic drugs on UACR or albuminuria outcomes at ≤ 1 year remains poorly studied. CONCLUSION Among the novel antidiabetic drugs, SGLT2 inhibitors consistently improved UACR and albuminuria outcomes in patients with T2D, with continuous treatment showing long-term benefit.

Abstract
Background: The aim of this study was to explore the predictive values of quantitative CT indices of the total lung and lung lobe tissue at discharge for the pulmonary diffusion function of coronavirus disease 2019 (COVID-19) patients at 5 months after symptom onset. Methods: A total of 90 patients with moderate and severe COVID-19 underwent CT scans at discharge, and pulmonary function tests (PFTs) were performed 5 months after symptom onset. The differences in quantitative CT and PFT results between Group 1 (patients with abnormal diffusion function) and Group 2 (patients with normal diffusion function) were compared by the chi-square test, Fisher’s exact test or Mann−Whitney U test. Univariate analysis, stepwise linear regression and logistic regression were used to determine the predictors of diffusion function in convalescent patients. Results: A total of 37.80% (34/90) of patients presented diffusion dysfunction at 5 months after symptom onset. The mean lung density (MLD) of the total lung tissue in Group 1 was higher than that in Group 2, and the percentage of the well-aerated lung (WAL) tissue volume (WAL%) of Group 1 was lower than that of Group 2 (all p < 0.05). Multiple stepwise linear regression identified only WAL and WAL% of the left upper lobe (LUL) as parameters that positively correlated with the percent of the predicted value of diffusion capacity of the lungs for carbon monoxide (WAL: p = 0.002; WAL%: p = 0.004), and multiple stepwise logistic regression identified MLD and MLDLUL as independent predictors of diffusion dysfunction (MLD: OR (95%CI): 1.011 (1.001, 1.02), p = 0.035; MLDLUL: OR (95%CI): 1.016 (1.004, 1.027), p = 0.008). Conclusion: At five months after symptom onset, more than one-third of moderate and severe COVID-19 patients presented with diffusion dysfunction. The well-aerated lung and mean lung density quantified by CT at discharge could be predictors of diffusion function in convalesce.

Abstract
Background Severe fever with thrombocytopenia syndrome (SFTS) is an infectious disease caused by a bunyaviridae virus. Its main clinical manifestation is fever with thrombocytopenia, which may be accompanied by other clinical symptoms. Here, we report a patient diagnosed with SFTS using metagenomic next‑generation sequencing (mNGS). Case Presentation A 56-year-old female patient was hospitalized with intermittent diarrhea and fever. She visited a local clinic for treatment, but instead of improving, the symptoms progressed to unconsciousness. Diagnosis Using mNGS, we isolated the bunyaviridae virus and several other pathogens from the patient’s blood samples to confirm the diagnosis. Interventions The patient was treated with symptomatic and supportive therapy, including intravenous human γ-globulin (20 g/d), platelet transfusion, platelet elevation (subcutaneous injection of recombinant human thrombopoietin, 15,000 IU), white blood cell elevation (subcutaneous injection of recombinant human granulocyte colony-stimulating factor, 200 ug, qd); and antibiotic (cefoperazone sodium and tazobactam sodium, 2 g, q8h), antiviral (ganciclovir, 250 mg, q12h), and antifungal therapy (voriconazole for injection, 0.2 g, q12h). After ten days of treatment, the patient’s condition gradually improved. Conclusion Compared to traditional detection methods, mNGS has many advantages. It can quickly identify the pathogen when the patient’s clinical manifestations are complex and difficult to diagnose, resulting in the formulation of an effective treatment.

Abstract
BACKGROUND Blood parameters, such as neutrophil-to-lymphocyte ratio, have been identified as reliable inflammatory markers with diagnostic and predictive value for the coronavirus disease 2019 (COVID-19). However, novel hematological parameters derived from high-density lipoprotein-cholesterol (HDL-C) have rarely been studied as indicators for the risk of poor outcomes in patients with severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) infection. Here, we aimed to assess the prognostic value of these novel biomarkers in COVID-19 patients and the diabetes subgroup. METHODS We conducted a multicenter retrospective cohort study involving all hospitalized patients with COVID-19 from January to March 2020 in five hospitals in Wuhan, China. Demographics, clinical and laboratory findings, and outcomes were recorded. Neutrophil to HDL-C ratio (NHR), monocyte to HDL-C ratio (MHR), lymphocyte to HDL-C ratio (LHR), and platelet to HDL-C ratio (PHR) were investigated and compared in both the overall population and the subgroup with diabetes. The associations between blood parameters at admission with primary composite end-point events (including mechanical ventilation, admission to the intensive care unit, or death) were analyzed using Cox proportional hazards regression models. Receiver operating characteristic curves were used to compare the utility of different blood parameters. RESULTS Of 440 patients with COVID-19, 67 (15.2%) were critically ill. On admission, HDL-C concentration was decreased while NHR was high in patients with critical compared with non-critical COVID-19, and were independently associated with poor outcome as continuous variables in the overall population (HR: 0.213, 95% CI 0.090-0.507; HR: 1.066, 95% CI 1.030-1.103, respectively) after adjusting for confounding factors. Additionally, when HDL-C and NHR were examined as categorical variables, the HRs and 95% CIs for tertile 3 vs. tertile 1 were 0.280 (0.128-0.612) and 4.458 (1.817-10.938), respectively. Similar results were observed in the diabetes subgroup. ROC curves showed that the NHR had good performance in predicting worse outcomes. The cutoff point of the NHR was 5.50. However, the data in our present study could not confirm the possible predictive effect of LHR, MHR, and PHR on COVID-19 severity. CONCLUSION Lower HDL-C concentrations and higher NHR at admission were observed in patients with critical COVID-19 than in those with noncritical COVID-19, and were significantly associated with a poor prognosis in COVID-19 patients as well as in the diabetes subgroup.

Abstract
Inflammation and oxidative stress are critical pathologies that contribute to sepsis-induced acute lung injury (ALI). This study investigated the regulatory role of estrogen-related receptor alpha (ERRα) in an experimental model of sepsis-induced ALI. In vivo, a cecal ligation and puncture- (CLP-) induced ALI model was established in anesthetized rats. Animals were then randomly assigned to receive an intraperitoneal injection of vehicle or ERRα inverse agonist (XCT-790, 2.5 mg/kg). Administration of XCT-790 significantly aggravated a sepsis-induced increase in pathological damage of lung tissues, lung endothelial permeability, myeloperoxidase (MPO) activity in lung tissues, production of serum inflammatory factors, and inflammatory cell accumulation in bronchoalveolar lavage fluid. In addition, XCT-790 treatment exacerbated a CLP-induced decrease in lung superoxide dismutase and an increase in lung malondialdehyde levels. In vitro, the exposure of rat pulmonary microvascular endothelial cells (PMVECs) to lipopolysaccharide (LPS) resulted in increased endothelial permeability and reduced expression of tight junction protein ZO-1, Occludin, JAM-A, and adherens junction protein VE-cadherin, which were further deteriorated by knockdown of ERRα. In addition, LPS-triggered inflammatory factor production and increase in the expression of phosphorylated IκBα and NF-κB p65 were also exacerbated by silencing ERRα gene. Meanwhile, knockdown of ERRα dramatically promoted LPS-activated mitochondrial reactive oxygen species production and LPS-induced downregulation of Sirt3 protein levels in rat PMVECs. Taken together, our present study provides evidences that ERRα functions as a novel negative modulator of sepsis-induced ALI in rats. The underlying mechanisms responsible for ERRα-elicited effects are largely dependent on the regulation of inflammatory response and oxidative stress.

Abstract
LncRNAs play crucial roles in the development of various cancers including hepatocellular carcinoma (HCC). Nevertheless, the function of the long noncoding RNA (lncRNA) FOXD2‐AS1 in HCC is still poorly understood. In this study, we focused on the role of FOXD2‐AS1 in HCC. We found that FOXD2‐AS1 was significantly upregulated in HCC cells in comparison to normal human liver cells, LO2. In this study, we also demonstrated that miR‐206 expression was greatly reduced in HCC cells. Furthermore, the inhibition of FOXD2‐AS1 repressed HCC cell proliferation, enhanced cell apoptosis, and restrained cell invasion and migration. The knockdown of FOXD2‐AS1 elevated miR‐206 expression, and we validated an interaction between these RNAs. Additionally, miR‐206 mimics inhibited HCC development while miR‐206 mimics had the opposite effect. MAP kinase 1 (MAP3K1) was predicted to be a target of miR‐206. We discovered that FOXD2‐AS1 modulated MAP3K1 expression by sponging miR‐206 in MHCC‐97L and HepG2 cells. Finally, our in vivo experiments validated that the knockdown of FOXD2‐AS1 inhibited HCC progression by modulating the miR‐206/MAP3K1 axis. In conclusion, this work implies FOXD2‐AS1 accelerates HCC progression through sponging miR‐206 and regulating MAP3K1 expression.

Abstract
Background: Diabetes correlates with poor prognosis in patients with COVID-19, but very few studies have evaluated whether impaired fasting glucose (IFG) is also a risk factor for the poor outcomes of patients with COVID-19. Here we aimed to examine the associations between IFG and diabetes at admission with risks of complications and mortality among patients with COVID-19. Methods: In this multicenter retrospective cohort study, we enrolled 312 hospitalized patients with COVID-19 from 5 hospitals in Wuhan from Jan 1 to Mar 17, 2020. Clinical information, laboratory findings, complications, treatment regimens, and mortality status were collected. The associations between hyperglycemia and diabetes status at admission with primary composite end-point events (including mechanical ventilation, admission to intensive care unit, or death) were analyzed by Cox proportional hazards regression models. Results: The median age of the patients was 57 years (interquartile range 38-66), and 172 (55%) were women. At the time of hospital admission, 84 (27%) had diabetes (and 36 were new-diagnosed), 62 (20%) had IFG, and 166 (53%) had normal fasting glucose (NFG) levels. Compared to patients with NFG, patients with IFG and diabetes developed more primary composite end-point events (9 [5%], 11 [18%], 26 [31%]), including receiving mechanical ventilation (5 [3%], 6 [10%], 21 [25%]), and death (4 [2%], 9 [15%], 20 [24%]). Multivariable Cox regression analyses showed diabetes was associated increased risks of primary composite end-point events (hazard ratio 3.53; 95% confidence interval 1.48-8.40) and mortality (6.25; 1.91-20.45), and IFG was associated with an increased risk of mortality (4.11; 1.15-14.74), after adjusting for age, sex, hospitals and comorbidities. Conclusion: IFG and diabetes at admission were associated with higher risks of adverse outcomes among patients with COVID-19.

Abstract
Purpose: To investigate the role of vagus nerve activation in the protective effects
of hypercapnia in ventilator-induced lung injury (VILI) rats. Methods: Male Sprague-Dawley rats were randomized to either high-tidal volume or
low-tidal volume ventilation (control) and monitored for 4h. The high-tidal
volume group was further divided into either a vagotomy or sham-operated
group and each surgery group was further divided into two subgroups:
normocapnia and hypercapnia. Injuries were assessed hourly through
hemodynamics, respiratory mechanics and gas exchange. Protein concentration,
cell count and cytokines (TNF-α and IL-8) in bronchoalveolar lavage fluid
(BALF), lung wet-to-dry weight and pathological changes were examined. Vagus
nerve activity was recorded for 1h. Results: Compared to the control group, injurious ventilation resulted in a decrease
in PaO2/FiO2 and greater lung static compliance, MPO
activity, enhanced BALF cytokines, protein concentration, cell count, and
histology injury score. Conversely, hypercapnia significantly improved VILI
by decreasing the above injury parameters. However, vagotomy abolished the
protective effect of hypercapnia on VILI. In addition, hypercapnia enhanced
efferent vagus nerve activity compared to normocapnia. Conclusion: These results indicate that the vagus nerve plays an important role in
mediating the anti-inflammatory effect of hypercapnia on VILI.

Abstract
The Prescription Appraisal Committee of the Central National Physician Pavilion was established on November 8, 1935. It specializes in handling cases where the parties entrusted by the Court have applied for re-identification against the identification of the local Chinese Medicine branch or medical group.The statutes of the Prescription Appraisal Committee stipulate the entrusted appraisers, the scope of appraisal, the appraisers, the appraisal process, and the signing and service of the appraisal opinions for the re-identification of TCM cases. To a certain extent, it played a role in improving the medical service environment of Chinese medicine at that time, safeguarding the common interests of doctors and patients, and promoting the institutionalized development of appraisal of Chinese medicine lawsuits in the Republic of China. However, due to historical reasons and limitations, it also had inherent limitations such as the uneven geographical distribution of appraisal candidates, the lack of strict identification procedures, and the inconsistency of appraisal standards.

Abstract
OBJECTIVE To investigate influences of estrogen-related receptor α(ERRα) on pulmonary vascular endothelium of rats undergoing sepsis. METHODS Male Sprague-Dawley (SD) rats were divided into four groups according to the random number table method (12 in each group): normal control group (NC group), sham operation group (Sham group), sepsis model caused by cecal ligation and puncture (CLP) group (CLP group), XCT790 intervention group (XCT790 group, given the XCT790 2.5 mg/kg via intraperitoneal injection 30 minutes before CLP). After 24 hours, rats were sacrificed and the organs were harvested. The pathological changes of lung tissue were observed using hematoxylin and eosin (HE) staining, and the ultrastructural changes of lung tissue were observed by double staining of uranium citrate with lead acetate, the degree of apoptosis of pulmonary capillary endothelial cells were observed by TdT-mediated dUTP nike end labeling stain (TUNEL), the permeability of lung vascular endothelial was detected by Evans blue (EB) staining, the levels of serum cytokines were detected by enzyme linked immunosorbent assay (ELISA), and white blood cell count in bronchial alveolar lavage fluid (BALF) was detected. RESULTS Compared with NC group and Sham group, the CLP group and XCT790 group had severe pathological damage and increased lung tissue permeability, the levels of serum cytokines and white blood cell count in BALF were increased. Compared with CLP group, the pathological changes of lung tissue, the degree of ultrastructural damage of lung tissue, the degree of apoptosis of lung capillary endothelial cells in XCT790 group further intensified, the permeability of lung endothelial barrier further increased [the content of EB (μg/g): 116.00±15.46 vs. 60.19±19.79, P < 0.05], and the level of serum cytokines further increased [interleukin-1β (IL-1β, ng/L): 71.38±4.01 vs. 56.58±2.45, interleukin-6 (IL-6, ng/L): 741.62±88.94 vs. 534.22±72.70, tumor necrosis factor-α (TNF-α, ng/L): 188.55±7.41 vs. 143.33±11.27, all P < 0.05], the white blood cell count in the BALF increased further (×104/L: 193.79±27.46 vs. 99.34±36.41, P < 0.05). CONCLUSIONS ERRα can aggravate inflammation in sepsis rats, destroy lung tissue and increase pulmonary permeability.

Abstract
This study was undertaken to examine the regulatory role of multidrug resistance-associated protein 4 (MRP4) in an experimental model of sepsis-induced acute lung injury in rats. Sepsis was induced by cecal ligation and puncture in anesthetized rats. Animals were then randomly assigned to receive intravenous injection of vehicle or MRP4 inhibitor (MK571, 20 mg/kg). The pathological changes were observed by hematoxylin and eosin staining. Lung water content, lung vascular permeability and inflammatory cell count in bronchoalveolar lavage fluid (BALF) were quantified. Serum tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels were measured. In addition, lung tissue cyclic adenosine monophosphate (cAMP) levels were examined by enzyme-linked immunosorbent assay. Furthermore, the effects of MRP4 knockdown on lipopolysaccharide (LPS)-induced endothelial permeability and the cytoskeleton of rat pulmonary microvascular endothelial cells (PMVECs) were detected. The protein expression levels of MRP4, Rac1, VE-cadherin, β-catenin and ZO-1 were measured by Western blot analysis. MK571 significantly reduced lung tissue damage, lung water content and lung vascular permeability. Lung tissue cAMP levels were attenuated in MK571-treated animals compared with vehicle controls. MK571 also decreased sepsis-induced inflammatory cell accumulation in BALF. In addition, the MK571 group had significantly lower serum TNF-α and IL-6 levels compared with vehicle controls. Consistently, knockdown of MRP4 protected against LPS-induced increase in the endothelial permeability and the destruction of cytoskeleton in vitro. Furthermore, silencing MRP4 gene significantly reduced MRP4 protein expression and restored the protein expression of Rac1, VE-cadherin, β-catenin and ZO-1 in rat PMVECs in response to LPS stimulation. These data suggest that inhibition of MRP4 significantly alleviates sepsis-induced acute lung injury in rats.

Abstract
OBJECTIVE To investigate the effect of multidrug resistance protein 4 (MRP4) overexpression on lipopolysaccharide (LPS)-induced vascular endothelial hyperpermeability of rat pulmonary micro-vascular endothelial cells (PMVECs) and its molecule mechanism. METHODS Three to six passages of PMVECs were cultured in vitro, and they were divided into three groups: the cells in LPS group were only challenged by LPS 10 μg/mL after being cultured in serum-free medium for 24 hours; the cells in Ad-shRNA and Ad-MRP4 groups were infected with the empty virus control or recombinant adenovirus expressing MRP4 for 2 hours, and then were cultured in serum-free medium for 24 hours followed by stimulation of LPS 10 μg/mL. Endothelial permeability was assayed by the Transwell chamber models at 2, 6, 12, and 24 hours after LPS stimulation. Intracellular cyclic adenosine monophosphate (cAMP) levels were detected by enzyme-linked immunosorbent assay (ELISA). The morphological characteristics and distribution of F-actin was determined by laser confocal fluorescence microscope. The protein expressions of MRP4, β-catenin, vascular endothelium-cadherin (VE-cad) and ZO-1 were measured by Western Blot. RESULTS (1) After LPS stimulation, endothelium permeability and intracellular cAMP levels in PMVECs were significantly increased, peaked at 12 hours, and then decreased after 24 hours. Compared with LPS group and Ad-shRNA group, PMVECs of Ad-MRP4 group were exhibited a significant increase in endothelial permeability [12-hour permeability (A value): 1.88±0.06 vs. 1.12±0.17, 1.10±0.18] and a significant decrease in intracellular cAMP level [12-hour cAMP (μg/L): 2.39±0.02 vs. 2.97±0.01, 3.00±0.02, all P < 0.05]. There was no significant difference in endothelium permeability and intracellular cAMP levels at all time points between the LPS group and the Ad-shRNA group (all P > 0.05). (2) Under laser confocal fluorescence microscope, after LPS stimulation, the stress fiber formation was induced in three groups. But there were pronounced irregular aggregation of fiber in PMVECs of Ad-MRP4 group. (3) Furthermore, compared with LPS group and Ad-shRNA group, protein expression of MRP4 in Ad-MRP4 group was dramatically increased (gray value: 0.76±0.03 vs. 0.44±0.02, 0.43±0.02, both P < 0.05), and the protein expressions of β-catenin, VE-cad, and ZO-1 were significantly decreased [β-catenin (gray value): 0.14±0.03 vs. 0.23±0.04, 0.23±0.03); VE-cad (gray value): 0.21±0.01 vs. 0.34±0.02, 0.35±0.04; ZO-1 (gray value): 0.14±0.02 vs. 0.37±0.06, 0.33±0.07, all P < 0.05]. There was no significant difference in all protein expressions between the LPS group and Ad-shRNA group (all P > 0.05). CONCLUSIONS MRP4 overexpression can decrease intracellular cAMP levels, reduce intercellular junction protein expression, and then exaggerate LPS-induced vascular endothelial hyperpermeability.

Abstract
Obesity and type 2 diabetes are the most common metabolic diseases globally. They are associated with inflammation, oxidative stress, autophagy, and insulin resistance. Sitagliptin, a dipeptidyl-peptidase 4 inhibitor, has been reported to show multiple biological activities beyond the antidiabetic property. This study was aimed at investigating the effect of sitagliptin on hepatic steatosis, insulin resistance, inflammation, and autophagy and exploring the underlying molecular mechanism. In the current study, ob/ob mice, a mouse model of genetic obesity and diabetes, were administered via gavage with sitagliptin 50 mg/kg daily for 4 weeks. Changes in glycolipid metabolism, inflammatory responses, and autophagy in the liver were evaluated. Body weight gain, lipid metabolic disorder, and hepatic steatosis as well as systemic and hepatic insulin sensitivity in ob/ob mice were significantly attenuated after sitagliptin treatment. Furthermore, sitagliptin decreased inflammatory responses by regulating macrophage M1/M2 polarization and inhibiting the activities of NF-κB and JNK. Moreover, sitagliptin increased the levels of phosphorylation of AMPK and decreased those of mTOR. This study indicates that sitagliptin significantly ameliorates the development of hepatic steatosis and insulin resistance in ob/ob mice by inhibiting inflammatory responses and activating autophagy via AMPK/mTOR signaling pathway.

Abstract
Our objective was to evaluate thyroid nodule malignancy prediction using thyroid function tests, autoantibodies, ultrasonographic imaging, and clinical data. We conducted a retrospective cohort study in 1400 patients with nodular thyroid disease (NTD). The thyroid stimulating hormone (TSH) concentration was significantly higher in patients with differentiated thyroid cancer (DTC) versus benign thyroid nodular disease (BTND) (p = 0.004). The receiver operating characteristic curve of TSH showed an AUC of 0.58 (95% CI 0.53-0.62, p = 0.001), sensitivity of 74%, and specificity of 57% at a cut-off of 1.59 mIU/L. There was an incremental increase in TSH concentration along with the increasing tumor size (p < 0.001). Thyroglobulin antibody (TgAb) concentration was associated with an increased risk of malignancy (p = 0.029), but this association was lost when the effect of TSH was taken into account (p = 0.11). Thyroid ultrasonographic characteristics, including fewer than three nodules, hypoechoic appearance, solid component, poorly defined margin, intranodular or peripheral-intranodular flow, and punctate calcification, can be used to predict the risk of thyroid cancer. In conclusion, our study suggests that preoperative serum TSH concentration, age, and ultrasonographic features can be used to predict the risk of malignancy in patients with NTD.

Abstract
The objective of this study was to reveal the exact role of Kupffer cells in the diet-induced insulin resistance, inflammation and liver autophagy. C57BL/6j male mice were fed with either chow diet or high-fat diet (HFD) for 12 weeks. Meanwhile, HFD feeding mice received an intraperitoneal injection of either 0.2% GdCl3 solution (20mg/kg) twice a week to deplete Kupffer cells or natural saline (5mL/kg) as control. The mRNA expressions of Kupffer cells markers (CD68 and F4/80), insulin sensitivity, TNF-α concentration and NF-κB activation and parameters of autophagy were assessed. Results demonstrated that CD68 and F4/80 mRNA expressions in the liver were up-regulated in HFD fed animals, while significantly reduced after GdCl3 administration. HFD feeding led to insulin resistance and TNF-α level and activation of NF-κB in insulin-sensitive tissues (liver, adipose tissue and skeletal muscle) were significantly elevated. Interestingly, alterations above were reversed by varying degrees but significantly after Kupffer cells depletion. Furthermore, western blot showed hepatic LC3-II as well as phosphorylation of AMPK in liver and skeletal muscle were significantly lower in mice fed HFD, and these changes dramatically ameliorated by GdCl3 treating. In conclusion, selective depletion of Kupffer cells significantly attenuated diet-induced insulin resistance, inflammation and promoted liver autophagy. Strategies targeting Kupffer cells function or autophagic processes could be a promising approach to counteract diet induced obesity and related metabolic disorders.

Abstract
OBJECTIVE To investigate the effects of catch-up growth (CUG) on the natch domain, leucine-rich repeat and PVD-containing protein 3 (NALP3) inflammasome pathway in visceral adipose tissue (VAT) and the mechanism of insulin resistance (IR) in CUG. METHODS Sprague-Dawley rats were randomly divided into the normal chow (NC) and the catch-up growth group (CUG). General characteristics, glucose infusion rate60-120 (GIR60-120) in hyperinsulinemic-euglycemic clamp and expression of NALP3 inflammasome, caspase1(p10) and IL-1β (p17) cleavage in VAT were respectively examined on week 4, 6 and 8 of the experiment. RESULTS After 4-week food restriction, lower percentage of abdominal fat mass (AFM%) was presented in the CUG group than the NC group [(11.54 ± 1.81)% vs (7.72 ± 1.47)%, P < 0.05]. In the CUG group, decreased expression of NALP3 inflammasome, caspase1 (p10) and IL-1β (p17) cleavage in VAT were found (0.47 ± 0.03 vs 0.28 ± 0.04, P < 0.01; 0.30 ± 0.02 vs 0.20 ± 0.03, P < 0.01; 0.52 ± 0.04 vs 0.37 ± 0.04, P < 0.05; respectively), whereas GIR60-120 was slightly improved [(23.47 ± 0.89) mg×min(-1)×kg(-1) vs (25.34 ± 1.16) mg×min(-1)×kg(-1), P > 0.05]. After refeeding, AFM% and the expression of NALP3 inflammasome, caspase1 (p10) and IL-1β (p17) cleavage in VAT in CUG group were shown to be increased with the time. Concomitant with those changes, GIR60-120 was gradually impaired. On week 4 of refeeding, AFM% and the expression of NALP3 inflammasome, caspase1 (p10) and IL-1β (p17) cleavage in VAT were significantly increased in the CUG group compared with the NC group [(12.52 ± 0.64)% vs (15.16 ± 1.10)%, P < 0.01; 0.52 ± 0.02 vs 0.65 ± 0.05, P < 0.05; 0.33 ± 0.03 vs 0.54 ± 0.02, P < 0.01; 0.55 ± 0.04 vs 0.65 ± 0.05, P < 0.05; respectively], while GIR60-120 was significantly attenuated [(21.45 ± 1.20) mg×min(-1)×kg(-1) vs (14.27 ± 1.06) mg×min(-1)×kg(-1), P < 0.05]. Correlation analysis showed that the expression of NALP3 and caspase1 (p10) in VAT were positively correlated with AFM% (r = 0.946, P < 0.01; r = 0.922, P < 0.01), while negatively correlated with GIR60-120 (r = -0.902, P < 0.01; r = -0.944, P < 0.01). CONCLUSION NALP3 inflammasome pathway in VAT is notably activated during CUG, which may contribute to the etiology of IR in CUG.

Abstract
INTRODUCTION Rotigaptide is a new anti-arrhythmic peptide, which has recently been found to increase junctional conductance and prevent ischemia-induced ventricular tachycardia. In this study, we attempted to investigate the effects and mechanisms of rotigaptide on the vulnerability to ventricular arrhythmias in rabbits with heart failure (HF). MATERIAL AND METHODS Chronic volume-pressure overload was used to induce HF. After rotigaptide infusion, an electrophysiological study was performed to record monophasic action potential (MAP), determine the effective refractory period (ERP) and ventricular fibrillation threshold (VFT), and assess the susceptibility to ventricular arrhythmia. Finally, real-time PCR was used to detect the changes of connexin 43 (Cx43) mRNA expression. RESULTS HF rabbits exhibited significant down-regulation of Cx43 mRNA, increase of effective refractory period (ERP) and decrease of VFT (p < 0.05, respectively). These changes resulted in an increase of vulnerability to ventricular tachyarrhythmias (VT/VF). Rotigaptide administration shortened ERP (113.3 ±8.6 ms vs. 131.7 ±12.5 ms, p < 0.05), restored VFT (15.0 ±2.0 V vs. 6.3 ±1.4 V, p < 0.05), and decreased the vulnerability to VT/VF. However, short-term rotigaptide treatment had no significant effect on MAP duration (MAP duration at 90% repolarization: 169.3 ±6.0 ms vs. 172.7 ±6.2 ms, p > 0.05) or connexin 43 mRNA expression (p > 0.05). CONCLUSIONS Rotigaptide decreases the ERP, elevates VFT, and reduces the vulnerability to ventricular arrhythmias without changing Cx43 expression in rabbits with HF. It may be a promising antiarrhythmic drug for preventing ventricular arrhythmia in HF.

Abstract
XRCC1 (human X-ray repair complementing defective repair in Chinese hamster cell 1) gene is considered a potentially important gene influencing the risk of hepatocellular carcinoma (HCC). Our analyses detected two allelic variants of XRCC1, c.910A>G and c.1686C>G. We aimed to investigate whether these polymorphisms influence the risk of HCC. The association between the XRCC1 polymorphisms and the risk of HCC was analyzed in 719 patients and 662 controls by polymerase chain reaction-restriction fragment length polymorphism. Our data suggested that the genotypes and alleles of c.910A>G and c.1686C>G polymorphisms were statistically associated with the risk of HCC. For c.910A>G, the GG genotype was associated with increased risk of developing HCC compared with the AA wild genotype (OR = 1.95, 95%CI = 1.40-2.70, P < 0.0001). For c.1686C>G, the risk of HCC was significantly higher for the GG genotype compared with the CC wild genotype (OR = 1.89, 95%CI = 1.375-2.599, P < 0.0001). Significant differences in the risk of HCC were also found with other genetic models for these two SNPs. The G allele of both c.910A>G and c.1686C>G may contribute to the risk of HCC (G versus A: OR = 1.40, 95%CI = 1.20-1.64, P < 0.0001 and G versus C: OR = 1.38, 95%CI = 1.19-1.61, P < 0.0001, respectively). Our findings suggest that the c.910A>G and c.1686C>G polymorphisms of XRCC1 are associated with the risk of HCC in the Chinese population.

Abstract
BACKGROUND The mechanisms underlying focal atrial tachycardia (AT) are unclear. METHODS In 14 pentobarbital anesthetized dogs, a right thoracotomy allowed electrical stimulation (ES) of the anterior right ganglionated plexi (ARGP). After ES was applied to the ARGP at baseline, atropine, 1 mg/cc, was injected into the ARGP and repeat stimulation applied. After a left thoracotomy (n = 8), a similar procedure was followed by atropine injected into the superior left (SL) GP. RESULTS ES (0.6-3.2 V) applied to the ARGP and SLGP caused an average reduction in sinus rate from 151 ± 14/min to 60 ± 11/min. At ≥4.5 V atrial fibrillation (AF) was induced (duration 48 ± 14 seconds). After injection of atropine into the ARGP or SLGP, ES applied to these GP induced no slowing of the sinus rate. Runs of AT were induced at an average voltage of 10 ± 2 V in 14 experiments (duration ≥4 minutes). AT was localized by ice mapping or by 3D noncontact mapping to the crista terminalis (n = 6), AV junction (n = 2) or a focal site at the left superior pulmonary vein (6). In AT lasting <4 minutes (n = 2), epinephrine injected into the GP significantly increased the AT duration. In 4/4 experiments, sustained AT could be terminated by intravenous esmolol. CONCLUSIONS Atropine injected into the ARGP or SLGP promotes ES-induced AT whose duration is increased by adrenergic agonists and terminated by beta blockade. Presumably cholinergic blockade and accentuated release of adrenergic neurotransmitters provide the AT mechanism. The induced AT was found to be localized at sites similar to those reported clinically.

Abstract
OBJECTIVE To investigate the effect of temperature on hospital admission among patients with chronic systolic heart failure (CSHF). METHODS Data regarding in-hospital patients with CSHF were gathered from 12 hospitals in Hubei province, between 2000 and 2010. Patients with a history of congenital heart disease and the history of cancer from this series, were excluded. Chi-square (χ(2)) tests and t tests were used for descriptive analysis. Univariate and multivariate logistic regression methods were performed to determinate the risk of hospital admission of every month to compare with the previous one. We used 2-tailed 95% confidence interval (CI), and tests with P < 0.01 to consider the significant levels, statistically. We also used the SPSS 13.0 for Windows, release 15, 2006 (SPSS Inc, Chicago, Ill) for data analyses. RESULTS (1) 48 964 patients were enrolled in the present study. The numbers of admission increased 18.71%, 13.84%, -21.90%, -34.62%, -21.97%, -3.81%, -2.04%, 10.13%, -17.13%, -0.85%, 21.54% and 42.70% from January to December when compared to the average number of admission. (2) The odds ratios (ORs) (95% CI, P values) of hospital admission in January, February and December were 1.09 (0.96 - 1.23, 0.54), 0.98 (0.84 - 1.10, 0.46) and 0.96 (0.84 - 1.08, 0.59), respectively in females which did not show any significant differences when compared to the number in August. However the ratios were 0.61 (0.54 - 0.69, < 0.01), 0.80 (0.68 - 0.92, < 0.01) and 0.73 (0.64 - 0.83, < 0.01), respectively, in males that showed significant differences when, compared to the figures in August. (3) The OR of admission increased more when temperature got lower for patients with coronary artery disease, hypertension heart disease or rheumatic heart disease, but not with dilated cardiomyopathy. (4) The OR of admission showed a different impact on patients with different occupation, along with the change of temperature. Low or high temperature did not seem to have different effects on the OR of admission in patients who were free-lanced or unemployed. CONCLUSION Temperature seemed to have significant effects on the risk of admission, which related to gender, etiology or occupation.

Abstract
Insulin therapy has been shown to contribute to extended glycemia remission in newly diagnosed patients with type 2 diabetes mellitus. This study investigated the effects of insulin treatment on pancreatic lipid content, and β-cell apoptosis and proliferation in glucose-intolerant rats to explore the protective role of insulin on β-cell function. A rat glucose-intolerant model was induced by streptozotocin and a high-fat diet. Plasma and pancreatic triglycerides, free fatty acids, and insulin were measured; and pancreatic β-cell cell apoptosis and proliferation were detected by a propidium iodide cell death assay and immunofluorescence for proliferating cell nuclear antigen. Relative β-cell area was determined by immunohistochemistry for insulin, whereas insulin production in pancreas was assessed by reverse transcriptase polymerase chain reaction. Islet β-cell secreting function was assessed by the index ΔI30/ΔG30. Glucose-intolerant rats had higher pancreatic lipid content, more islet β-cell apoptosis, lower β-cell proliferation, and reduced β-cell area in pancreas when compared with controls. Insulin therapy reduced blood glucose, inhibited pancreatic lipid accumulation and islet β-cell apoptosis, and increased β-cell proliferation and β-cell area in glucose-intolerant rats. Furthermore, impaired insulin secretion and insulin production in glucose-intolerant rats were improved by insulin therapy. Insulin can preserve β-cell function by protecting islets from glucotoxicity and lipotoxicity. It can also ameliorate β-cell area by enhancing β-cell proliferation and reducing β-cell apoptosis.

Abstract
PURPOSE To investigate and compare the effects of propofol and midazolam on inflammation and oxidase stress in children with congenital heart disease undergoing cardiac surgery. MATERIALS AND METHODS Thirty-two ASA class I-II children with congenital heart disease undergoing cardiac surgery were randomly divided into two groups: propofol combined with low dose fentanyl (PF group, n = 16) and midazolam combined with low dose fentanyl (MF group, n = 16). Tracheal extubation time and length of Intensive Care Unit (ICU) stay were recorded. Blood samples were taken before operation (T₀), at 2 h after release of the aorta cross-clamp (T₃) and at 24 h after operation (T₄) to measure interleukin 6 (IL-6), IL-8, superoxide dismutase (SOD) and malondialdehyde (MDA) levels. Myocardium samples were collected at 10-20 min after aorta cross-clamp (T₁) and at 10-20 min after the release of the aorta cross-clamp (T₂) to detect heme oxygenase-1 (HO-1) expression. RESULTS Tracheal extubation time and length of ICU stay in PF group were significantly shorter than those of the MF group (p < 0.05, respectively). After cardiopulmonary bypass, IL-6, IL-8 and MDA levels were significantly increased, and the SOD level was significantly reduced in both two groups, but PF group exhibited lower IL-6, IL-8 and MDA levels and higher SOD levels than the MF group (p < 0.05, respectively). The HO-1 expression in the PF group was significantly higher than that in MF group at the corresponding time points (p < 0.05, respectively). CONCLUSION Propofol is superior to midazolam in reducing inflammation and oxidase stress and in improving post-operation recovery in children with congenital heart disease undergoing cardiac surgery.

Abstract
OBJECTIVE To observe the cardioprotective effects of propofol and midazolam in children with congenital heart diseases undergoing open heart surgery. METHODS Thirty-two children with cyanotic congenital heart diseases of ASA classes I - II were randomly divided into 2 equal groups: propofol combined with low dose fentanyl group (Group PF) and midazolam combined with low dose fentanyl group (Group MF). The changes of hemodynaics, ECG, SpO2, nasopharyngeal and rectal temperatures were monitored continuously. The time of tracheal extubation and ICU staying time were recorded. Venous blood samples were collected when the venous channel was opened (T(0)), 2 h after declamping of the aorta (T(4)), and 24 h after operation (T(5)) to detect the plasma cardiac troponin I (cTnI). Myocardium samples were collected 10 - 20 min after aorta cross-clamp (T(2)), and 10 - 20 min after declamping of the aorta (T(3)) to undergo immunohistochemistry to observe the expression of heme oxygenase-1 (HO-1). RESULTS The tracheal time of Group GF was 14.17 h, significantly shorter than that of Group MF (23.65 h, P < 0.05), and the ICU staying time of Group GF was 30.17 h, significantly shorter than that of Group MF (49.47 h, P < 0.05). The plasma cTnI level at T(4) of Group GF was 97 ng/ml +/- 33 ng/ml, significantly higher than those at T(0) (0.17 ng/ml +/- 0.10 ng/ml, P < 0.01) and T(5) (23 ng/ml +/- 13 ng/ml, P < 0.01). The plasma cTnI level at T(4) of Group MF was138 ng/ml +/- 56 ng/ml, significantly higher than those at T(0) (0.62 ng/ml +/- 0.96 ng/ml, P < 0.01) and T(5) (24 ng/ml +/- 6 ng/ml, P < 0.01). And the plasma cTnI levels at T(5) of these 2 groups were both significantly higher than those at T(0) (both P < 0.01), however, there was no significant difference in the plasma cTnI level at any time point between these 2 groups. The grey values of HO-1 in cardiac muscle cells at T(2) of Groups GF and MF were 182.2 +/- 0.8 and 193.5 +/- 1.4, both significantly higher than those at T(3) (125.6 +/- 2.1 and 145.5 +/- 7.4 respectively, both P < 0.01), and the grey values of HO-1 in cardiac muscle cells at T(2) and T(3) of Group MF were both significantly higher than those of Group GF (both P < 0.05). CONCLUSION Both propofol and midazolam have protective effects for the children with congenital heart diseases undergoing open heart surgery, and propofol is superior to midazolam in the cardioprotection.

Abstract
OBJECTIVE To observe the effect of Chinese herbs for supplementing Shen and strengthening bone (HB) on myelogenic osteoclasts formation, and gene expression of interleukin-6 (IL-6), IL-6 receptor (IL-6R) and gp130 in bone marrow. METHODS Seventy-two healthy female SD rats of 3 months, were randomly divided into three groups, 24 in the sham-operated group (A), 24 in the ovariectomized group (B) and 24 in the after ovariectomy HB treated group (C). Bone marrow cells of 6 rats from each group were respectively collected and cultured at four time points (2nd, 4th, 6th and 12th weeks after operation). After 6 days of culture, the bone marrow cells were differentiated by Wright-Giemsa stain and TRAP stain, and total RNA in them was extracted by TRIZOL. RESULTS Beginning from the 2nd week, the osteoclasts formation in Group B was higher than that in Group A (P < 0.05), and IL-6, IL-6R gene expression significantly increased in Group B (P < 0.05 or P < 0.01). These changes reached the peak in the 4th to 6th week, with the level maintained to the 12th week. As for comparison of Group B and C, the above-mentioned changes were significantly weakened in the latter (P < 0.05 or P < 0.01). No significant change of gp130 gene expression revealed in the whole course in either group. CONCLUSION HB could inhibit the myelogenic osteoclasts formation in ovariectomized rats, this effect may be correlated with, partially at least, its inhibitory effect on the over-expressed IL-6 and IL-6R gene expression in myelocytes after ovariectomy.
