Abstract
Background The mortality risk related to anaesthesia in China remains poorly characterized. The objective of this study was to evaluate the anaesthesia-related mortality in terms of its incidence, changes, causes and preventability in Hubei, China, between 2017 and 2021 using a series of annual surveys. Methods We prospectively collected information on patient, surgical, anaesthesia, and hospital characteristics for 9,391,669 anaesthesia procedures performed between 2017 and 2021 in 10 cities within Hubei Province, China. Anaesthesia-related death was defined as death that deemed to be entirely or partially attributable to anaesthesia, occurring within 24 h following anaesthesia administration. All fatalities were scrutinized consecutively to determine their root causes and preventability. The incidence and patterns of anaesthesia-related deaths were analysed from 2017 to 2021. A mixed-effects model with a Poisson link function was fitted to evaluate the city-level annual changes in risk-adjusted incidence of anaesthesia-related deaths. Findings 600 cases of anaesthetic deaths occurred from 2017 to 2021, yielding an incidence of 6.4 per 100,000 anaesthesia procedures [95% confidence interval (95% CI): 5.9, 6.9], and most were preventable (71.3%). There was a significant decrease from 2017 to 2021, in the incidences of anaesthesia-related death across all patients, those with American Society of Anaesthesiologists physical status (ASAPS) ≥III, and those who had general anaesthesia, with a percentage reduction of 57.6%, 59.1%, and 55.9%, respectively. The risk-adjusted annual changes indicated significant downward trends for the incidence of anaesthetic mortality from 2017 to 2018, 2019, 2020, and 2021. For instance, the risk-adjusted annual changes for the anaesthetic mortality incidence from 2017 to 2021 was -2.5 (95% CI: -1.4, -4.7). Interpretation In this large, comprehensive database study conducted in Central China, the anaesthesia-related death incidence was 6.4 per 100,000. Notably, the incidence of anaesthesia-related deaths decreased between 2017 and 2021. However, further in-depth analysis is needed to understand the extent to which these trends represent a change in patient safety.

Abstract
At present, the application of machine vision methods for roughness measurement in production sites is limited by its adaptability to illumination variations during the measurement. In this study, a machine vision method for roughness measurement with robustness to illumination is proposed so as to explore the functions of its color image indices in improving the mathematical expression of the vector of three primary colors. Besides, virtual images of different-roughness surfaces were analyzed, the effects of the samples' surface texture orientations on measurement indices were discussed, and the singular value ratio was derived as an index for evaluating roughness. The experimental results showed that the samples' index values remained unchanged when the illumination was increased for both vertical and horizontal surface textures, indicating that the proposed method has strong robustness to illumination. In addition, the experimental results were verified by a support vector machine (SVM)-based method using 10 different-roughness test samples, with the verification range of 0.127-2.245 µm. It was found that the measurement accuracy reached 90%, suggesting that the proposed method is reasonable and feasible, and shows certain potential to be applied in engineering.

Abstract
MicroRNAs (miRNAs) are an important class of non-coding small RNAs that regulate the expression of target genes through mRNA cleavage or translational inhibition. Previous studies have revealed their roles in regulating seed dormancy and germination in model plants such as Arabidopsis thaliana, rice (Oryza sativa) and maize (Zea mays). However, the miRNA response to exogenous gibberellic acid (GA) and abscisic acid (ABA) during seed germination in maize has yet to be explored. In this study, small RNA libraries were generated and sequenced from maize embryos treated with GA, ABA or double-distilled water as control. A total of 247 miRNAs (104 known and 143 novel) were identified, of which 45 known and 53 novel miRNAs were differentially expressed in embryos in the different treatment groups. In total, 74 (37 up-regulated and 37 down-regulated) and 55 (23 up-regulated and 32 down-regulated) miRNAs were expressed in response to GA and to ABA, respectively, and a total of 18 known and 38 novel miRNAs displayed differential expression between the GA- and ABA-treated groups. Using bioinformatics tools, we predicted the target genes of the differentially expressed miRNAs. Using GO enrichment and KEGG pathway analysis of these targets, we showed that miRNAs differentially expressed in our samples affect genes encoding proteins involved in the peroxisome, ribosome and plant hormonal signalling pathways. Our results indicate that miRNA-mediated gene expression influences the GA and ABA signalling pathways during seed germination.

Abstract
This study observed the clinical efficacy of pre-injection of dexmedetomidine of different doses before surgery and the adverse reactions during the recovery period in pediatric intravenous general anesthesia without tracheal intubation. Pediatric patients who received general anesthesia without tracheal intubation before surgery from January 2016 to March 2017 were randomly divided into four groups (n=30), and were respectively treated with intravenous pump infusion of loaded dexmedetomidine of high-dose (2.5 µg/kg), middle-dose (1.5 µg/kg) and low-dose (0.5 µg/kg), while the children in the control group received injection of normal saline in same dose. Then, the mean arterial pressure (MAP) at different time points (5 and 10 min after administration, after anesthesia and after surgery), heart rate, Ramsay sedation score changes and adverse reactions during recovery period of anesthesia of pediatric patients were compared among four groups. At 5 and 10 min after administration, Ramsay scores of high-dose group and middle-dose group were higher than that of the control group, and the differences had statistical significance (P<0.05). There was no significant difference in comparison of Ramsay scores between low-dose group and the control group. The MAP and heart rate after anesthesia and after surgery of pediatric patients with pump infusion of dexmedetomidine in the three groups were decreased significantly compared to those of the control group, and the differences had statistical significance (P<0.05). The incidence rate of adverse reaction of pediatric patients during the recovery period after pump infusion in the three groups and the control group was, respectively, 13/30, 8/30, 7/30 and 8/30, and the differences were statistically significant (P<0.05). The sedative effect and safety of pre-injection of dexmedetomidine in pediatric intravenous general anesthesia without tracheal intubation are promising, and the medium dosage can maximize the anesthetic effect with less side effects.

Abstract
BACKGROUND Methylation of the Ras-association domain family 1 isoform A (RASSF1A) gene promoter region is thought to participate in the initiation and development of many different cancers. However, in bladder cancer the role of RASSF1A methylation was unclear. To evaluate the relationship between RASSF1A methylation and bladder cancer, a quantitative assessment of an independent meta-analysis was performed. In addition, a DNA methylation microarray database from the cancer genome atlas (TCGA) project was used to validate the results of the meta-analysis. METHODS We searched published articles from computerized databases, and DNA methylation data were extracted from TCGA project. All data were analyzed by R software. RESULTS The results of the meta-analysis indicated that the frequency of RASSF1A gene methylation in bladder cancer patients is significantly higher than in healthy controls. The hazard ratio (HR) was 2.24 (95% CI = [1.45; 3.48], P = 0.0003) for overall survival (OS), and the RASSF1A gene promoter methylation status was strongly associated with the TNM stage and differentiation grade of the tumor. The similar results were also found by the data from TCGA project. CONCLUSION There was a significant relationship between the methylation of the RASSF1A gene promoter and bladder cancer. Therefore, RASSF1A gene promoter methylation will be a potential biomarker for the clinical diagnosis of bladder cancer.

Abstract
Objective The aim of this study was to investigate the effects of docosahexaenoic acid (DHA) on the generation of angiopoietin-2 (Ang-2) by rat brain microvascular endothelial cells under an oxygen- and glucose-deprivation environment (OGD), and its relationship, if any, with cyclooxygenase 2 (COX-2) expression. Methods Annexin V and propidium iodide apoptosis assay was used to detect apoptosis. Enzyme linked immunosorbent assay was used to detect Ang-2, vascular endothelial growth factor (VEGF), prostaglandin E2 (PGE2), and prostaglandin I2 (PGI2) content. Reverse transcription polymerase chain reaction (RT-PCR) was used to detect Ang-2 and VEGF mRNA expression. Western blot was used to detect expression of COX-2 protein. Results DHA reduced the apoptosis rate (P = 0.026) and decreased the secretion of Ang-2, VEGF, PGE2, and PGI2 (P = 0.006, P = 0.000, P = 0.002, P = 0.004 respectively). The relative expression of Ang2 and Vegf mRNA, as well as COX-2 expression, also decreased (P = 0.000, P = 0.005, P = 0.007 respectively). These effects were antagonized by GW9662 (peroxisome proliferator-activated receptor-γ antagonist). COX-2 protein expression levels were positively correlated with Ang2 and Vegf mRNA expression levels (γ = 0.69, P = 0.038 and γ = 0.76, P = 0.032, respectively). Ang-2 and VEGF mRNA levels were positively correlated with Ang-2 (γ = 0.84, P = 0.012) and VEGF (γ = 0.71, P = 0.036) secretion levels respectively. Conclusion DHA reduced apoptosis induced by an OGD environment, thus decreasing Ang-2 and VEGF synthesis. This phenomenon was associated with a decrease in COX-2 protein expression, PGE2 and PGI2 secretion, and generation regulation via intracellular transcriptional pathways.

Abstract
Heart rate variability (HRV) was used in the present study to evaluate a target-controlled approach compared with a constant-rate infusion for remifentanil anesthesia during off-pump coronary artery bypass grafting (OP-CABG) surgery. A total of 65 patients with American Society of Anesthesiologists (ASA) physical status II or III, who were aged 60–85 years and scheduled for OP-CABG, were selected for the study. All patients were administered an intramuscular premedication of 10 mg morphine and 0.3 mg scopolamine. In group I, remifentanil was infused using a target-controlled approach at 1.5–5.0 ng/ml, and in group II, remifentanil was infused at a constant-rate of 0.05–1.0 μg/kg/min and at additional single increments of 1 μg/kg when appropriate. The heart rate and other hemodynamic monitoring indices of the patients, including the mean arterial pressure, central venous pressure, pulmonary artery pressure and pulmonary capillary wedge pressure, were monitored at various time points, including prior to induction (T0), at extubation (performed intraoperatively; T7) and at 24 h post-surgery. The HRV indices, including total power (TP), low frequency (LF) and the LF/high frequency (HF) ratio of power (LF/HF), were reduced following induction at T0 and remained low at 24 h post-surgery. At T5 (right coronary or left circumflex artery anastomosis) and T7 (tracheal extubation), all the HRV indices, with the exception of the HF power, were significantly increased (P<0.05). Additionally, the TP, LF and LF/HF values in group II were higher at T5 compared with those in group I (P<0.05). Remifentanil target-controlled infusion is superior to constant-rate infusion in suppressing the stress response during OP-CABG, maintaining the balance of the cardiac autonomic nervous system and promoting the recovery of the autonomic function following surgery.

Abstract
SUMMARY We compared skeletal parameters in type 2 diabetic (T2DM) and non-diabetic postmenopausal women. Bone structure by dual energy x-ray absorptiometry (DXA) and HR-pQCT was not different, although procollagen type 1 amino-terminal propeptide (P1NP) and osteocalcin levels were lower in T2DM. INTRODUCTION T2DM is associated with increased fracture risk, but, paradoxically, with higher cross-sectional bone density (BMD) as measured by DXA. We sought explanations to this puzzle by investigating detailed structural and biochemical skeletal parameters in T2DM. METHODS Cross-sectional comparison of 25 postmenopausal T2DM women and 25 matched controls using DXA, high-resolution peripheral quantitative computed tomography (HR-pQCT) and biochemical bone turnover markers. RESULTS BMD by DXA did not differ between T2DM and controls. HR-pQCT assessment also did not differ, with the exception of cortical area at the tibia, which tended to be lower in the diabetics (difference of 12 ± 6 [mean ± SD] mm, p = 0.06). P1NP and osteocalcin levels were lower in T2DM as compared to controls (P1NP, 34.3 ± 16 vs. 57.3 ± 28 ng/ml; p = 0.005; osteocalcin, 4.5 ± 2 vs. 6.2 ± 2 nmol/L; p = 0.001). CONCLUSIONS Postmenopausal women with T2DM had lower levels of bone formation markers as compared to controls. Aside from a possible decrease in cortical bone area at a weight-bearing site, bone structure was not altered in T2DM. Lower bone turnover may be a skeletal parameter that is present in T2DM.

Abstract
UNLABELLED We evaluated vitamin D status in HIV+ and HIV- postmenopausal African-American (AA) and Hispanic women. Most women (74-78%) had insufficient 25-hydroxyvitamin D (25OHD) levels, regardless of HIV status. 25OHD was lower in AA women and women lacking supplement use, providing support for screening and supplementation. Among HIV+ women, 25OHD was associated with current CD4 but not type of antiretroviral therapy. INTRODUCTION To evaluate vitamin D status and factors associated with vitamin D deficiency and insufficiency in HIV-infected (HIV+) postmenopausal minority women. METHODS In this cross-sectional study, 89 HIV+ and 95 HIV- postmenopausal women (33% AA and 67% Hispanic) underwent assessment of 25OHD, 1,25-dihydroxyvitamin D, parathyroid hormone, markers of bone turnover and bone mineral density by dual energy X-ray absorptiometry. RESULTS The prevalence of low 25OHD did not differ by HIV status; the majority of both HIV+ and HIV- women (74-78%) had insufficient levels (<30 ng/ml). Regardless of HIV status, 25OHD was significantly lower in AA subjects, and higher in subjects who used both calcium and multivitamins. In HIV+ women on antiretroviral therapy (ART), 25OHD was directly associated with current CD4 count (r=0.32; p<0.01) independent of age, ethnicity, BMI, or history of AIDS-defining illness. No association was observed between 1,25(OH)(2)D and CD4 count or between serum 25OHD, 1,25(OH)(2)D or PTH and type of ART. CONCLUSIONS In postmenopausal minority women, vitamin D deficiency was highly prevalent and associated with AA race and lack of supplement use, as well as lower current CD4 cell count. These results provide support for screening and repletion of vitamin D in HIV+ patients.

Abstract
Marijuana use activates cannabinoid receptors (CB-Rs) producing several behavioral effects related to addiction, mood, and appetite. We investigated the association between CNR2 gene, which encodes cannabinoid CB2 receptor (CB2-R) and eating disorders in 204 subjects with eating disorders and 1876 healthy volunteers in Japanese population. The effect of treatment with CB2-R ligands on mouse food consumption was also determined. The CB2-R ligands used suppressed food intake in a time- and strain-dependent manner when food was available ad libitum and during the 12-h fast except, AM 630-the CB2-R antagonist that stimulated food consumption in food-deprived mice. There is an association between the R63Q polymorphism of the CNR2 gene and eating disorders (P = 0.04; Odds ratio 1.24, 95% CI, (1.01-1.53). These results suggest that cannabinoid CB2-R is involved in the endocannabinoid signaling mechanisms associated with the regulation of food intake and in eating disorders.

Abstract
Brachydactyly type A-1 (BDA-1; MIM 112500) is characterized by shortening or missing of the middle phalanges (Fig. 1a). It was first identified by Farabee in 1903 (ref. 2), is the first recorded example of a human anomaly with Mendelian autosomal-dominant inheritance and, as such, is cited in most genetic and biological textbooks. Here we show that mutations in IHH, which encodes Indian hedgehog, cause BDA-1. We have identified three heterozygous missense mutations in the region encoding the amino-terminal signaling domain in all affected members of three large, unrelated families. The three mutant amino acids, which are conserved across all vertebrates and invertebrates studied so far, are predicted to be adjacent on the surface of IHH.

Abstract
Potent and selective active-site-spanning inhibitors have been designed for cathepsin K, a cysteine protease unique to osteoclasts. They act by mechanisms that involve tight binding intermediates, potentially on a hydrolytic pathway. X-ray crystallographic, MS, NMR spectroscopic, and kinetic studies of the mechanisms of inhibition indicate that different intermediates or transition states are being represented that are dependent on the conditions of measurement and the specific groups flanking the carbonyl in the inhibitor. The species observed crystallographically are most consistent with tetrahedral intermediates that may be close approximations of those that occur during substrate hydrolysis. Initial kinetic studies suggest the possibility of irreversible and reversible active-site modification. Representative inhibitors have demonstrated antiresorptive activity both in vitro and in vivo and therefore are promising leads for therapeutic agents for the treatment of osteoporosis. Expansion of these inhibitor concepts can be envisioned for the many other cysteine proteases implicated for therapeutic intervention.

Abstract
The metabolic fate of SK&F 107461 [Cbz-Ala-Ala-Phe psi [CHOHCH2] Gly-Val-Val-OMe], a potent and specific inhibitor of the protease encoded by human immunodeficiency virus type 1, in male Sprague-Dawley rats is described. SK&F 107461 is a hexapeptide analog containing a hydroxyethylene linkage in place of one of the peptide bonds, and in which the amino terminus is blocked with a carbobenzyloxy group and the carboxy terminus is modified to a methyl ester. The major metabolites of SK&F 107461 found in bile and urine after intravenous administration of 3H-labeled compound were characterized by LC/MS using either thermospray or continuous flow/FAB models of ionization. Approximately 80% of the administered radioactivity was recovered in the bile of bile duct-exteriorized rats following an intravenous dose. Radiochromatographic profiling indicated that SK&F 107461 was subject to extensive biotransformation. Structures were determined for three major biliary and five major urinary metabolites. Two of the major circulating plasma metabolites observed after intravenous bolus administration had similar retention times to metabolites that were observed in both bile and urine. A pathway for the biotransformation of SK&F 107461 in the rat is proposed. The parent molecule underwent two primary modes of metabolism. Hydrolysis of the carboxy-terminal ester or hydrolysis of the Ala-Ala peptide bond near the amino terminus were the primary metabolic events. All of the other metabolites characterized can be accounted for by exopeptidase activity subsequent to one or both of these primary events. There were no major metabolites observed resulting from anything other than hydrolysis of the ester or peptide bonds in the parent molecule.

Abstract
Rat aortic smooth muscle cells were used as a model system to characterize the binding properties of [3H]SK&F 108566, an angiotensin type-1 (AT1) receptor antagonist. The binding was specific, saturable and reversible. The association and dissociation rates of [3H]SK&F 108566 binding to smooth muscle cells were monophasic and Scatchard analysis of equilibrium binding data yielded a linear plot indicating a homogenous population of binding sites. The maximum binding (Bmax) and apparent dissociation constant (Kd) were 22,000 +/- 6000 sites/cell and 0.83 +/- 0.08nM respectively. The pharmacological specificity of [3H]SK&F 108566 binding to smooth muscle cells is consistent with that observed for AT1 and confirms AT1 receptor specificity of this radioligand. High affinity binding was observed in membranes prepared from bovine adrenal cortex, rat liver and rat kidney glomeruli. COS cells transfected with cDNA encoding human AT1 angiotensin II receptors also displayed high affinity binding site for [3H]SK&F 108566. No specific binding could be detected on membranes prepared from bovine cerebellum, a tissue rich in the angiotensin type-2 (AT2) receptor. These observations indicate that [3H]SK&F 108566 binds to sites which have pharmacological characteristics of angiotensin II AT1 subtype receptors and can be used as a subtype-selective radioligand to characterize AII receptors in various systems.

Abstract
Fifty-nine patients with hepatoma associated with advanced esophageal varices who received a variety of therapeutic modalities in the past 10 years at our department were reviewed. Our therapeutic modalities are hepatic resection, hepatic artery ligation (HAL) and trans-arterial embolization (TAE) for those with hepatoma and non-shunting treatment (NST; esophageal transection or Hassab's procedure) and endoscopic sclerotherapy (ST) for those with esophageal varices. A patient selection was made by our own criterial developed by a multiple regression analysis for the hepatoma and KICG value for esophageal varices. Out of 59.16 underwent hepatic resection and NST. Eight survived more than 2 years. The longest survivor has been living for 4 yr and 4 months. Two-year survival rate is 69.8%. Another 16 underwent HAL and NST. Two-year survival was 14.6%. Another 7 underwent ST following hepatic resection or HAL. Five of the 7 received an emergency ST. Hemostasis was achieved in all of them. Two-year survival was 21.8%. The remaining 20 underwent ST and TAE; 13 received an emergency ST with 85% of hemostasis rate. None of them survived more than 2 years. From these data, it is suggested that a proper selection of patients for a proper therapeutic modality improves the prognosis even in those with hepatoma associated with advanced esophageal varices.

Abstract
Four cases of foreign bodies in the duodenum were treated using a flexible fibre-optic panendoscope. All the patients were boys and eight months to four years of age. The ingested foreign materials were an injection needle, a marking pin, a hairpin and a curtain hook. Endoscopic extraction was attempted, because the ingested objects might cause perforation or obstruction of the gastrointestinal tract. Until recently, they had to be carefully watched or prophylactic operation suggested. Under general anaesthesia, duodenal endoscopy was easily performed and extraction of foreign bodies was not found to be difficult during infancy. This is considered to be a safer and less hazardous way than careful watching or prophylactic operation.

Abstract
A simultaneous manometric monitoring of the common bile duct (CBD) and the duodenum were performed 2 weeks after choledocholithotomy on 15 patients whose common bile ducts were explored without sphincteroplasty and 30 patients with sphincteroplasty. These manometric studies were carried out by open-tip catheters intubated into the CBD and duodenum through the T-tube at the operation. In patients without sphincteroplasty, no effects of the duodenal pressure on a CBD pressure profile were recognized, while a synchronized pressure profile of the CBD and the duodenum was obtained in patients with sphincteroplasty. By stimulation with morphine (Morphine sulfate; 0.17 mg/Kg iv bolus), waxing and waning of the pressured in the CBD without sphincteroplasty were observed with 20 cmH2O in maximum at about 13 minutes after injection. However, in the CBD with sphincteroplasty, scale-over increase of the pressure curve was seen immediately after duodenal contraction caused by morphine stimulation. A direct infusion of 5 ml of 0.1 N hydrochloride to the duodenum causes hyperperistalsis of the duodenum, which made a synchronized pressure profile in the CBD with sphincteroplasty but made no remarkable change in a pressure profile of the CBD without sphincteroplasty. These findings conclude that the sphincter of Oddi plays an important role as a "pressure barrier" between the CBD and the duodenum, and that with the destruction of this sphincter by sphincteroplasty, a pressure profile of the CBD becomes close to that of the duodenum. This simultaneous manometric study of the CBD and the duodenum might be one of most valuable methods for evaluation of completeness of the sphincteroplasty.
