Abstract
Objectives The prospect of extended reality (XR) being integrated with surgical training curriculum has attracted scholars. However, there is a lack of bibliometric analysis to help them better understand this field. Our aim is to analyze relevant literature focusing on development trajectory and research directions since the 21st century to provide valuable insights. Methods Papers were retrieved from the Web of Science Core Collection. Microsoft Excel, VOSviewer, and CiteSpace were used for bibliometric analysis. Results Of the 3337 papers published worldwide, China contributed 204, ranking fifth. The world's enthusiasm for this field has been growing since 2000, whereas China has been gradually entering since 2001. Although China had a late start, its growth has accelerated since around 2016 due to the reform of the medical postgraduate education system and the rapid development of Chinese information technology, despite no research explosive period has been yet noted. International institutions, notably the University of Toronto, worked closely with others, while Chinese institutions lacked of international and domestic cooperation. Sixteen stable cooperation clusters of international scholars were formed, while the collaboration between Chinese scholars was not yet stable. XR has been primarily applied in orthopedic surgery, cataract surgery, laparoscopic training and intraoperative use in neurosurgery worldwide. Conclusions There is strong enthusiasm and cooperation in the international research on the XR-based surgical training. Chinese scholars are making steady progress and have great potential in this area. There has not been noted an explosive research phase yet in the Chinese pace. The research on several surgical specialties has been summarized at the very first time. AR will gradually to be more involved and take important role of the research.

Abstract
Background and Objective Increasing evidence suggests that inflammation plays an essential role in cancer development and progression. The levels of inflammation-related indicators are correlated with prognosis across a wide variety of tumor types, including prostate cancer (PCa), but its diagnostic and prognostic value in PCa remains controversial. In the present review, the diagnostic and prognostic value of inflammation-related indicators in PCa patients is investigated. Methods A literature review was performed using the PubMed database, screening articles from English and Chinese journals published mainly from 2015 to 2022. Key Content and Findings Inflammation-related indicators based on haematological tests have some diagnostic and prognostic value not only when used alone but also in combination with common clinical indicators such as prostate-specific antigen (PSA), and can significantly improve the accuracy of diagnostic results. Elevated neutrophil-to-lymphocyte-count ratio (NLR) is strongly associated with the detection of PCa in men with PSA levels of 4-10 ng/mL. Preoperative NLR levels in localized PCa patients affect their overall survival (OS), cancer-specific survival (CSS), and biochemical recurrence-free survival (BCRFS) after radical prostatectomy (RP). In patients with castration-resistant prostate cancer (CRPC), a high NLR is associated with poorer OS, progression-free survival (PFS), CSS, and radiographic PFS. Platelet-to-lymphocyte-count ratio (PLR) appears to have the greatest accuracy in predicting an initial diagnosis of clinically significant PCa. The PLR also has the potential to predict the Gleason score. Patients with higher PLR levels have a higher risk of death compared to those with a lower PLR. Elevated procalcitonin (PCT) is correlated with the development of PCa and may be useful in improving the diagnostic accuracy of PCa. Elevated C-reactive protein (CRP) levels are an independent predictor of poorer OS in metastatic PCa. Conclusions Numerous studies have been conducted on the value of inflammation-related indicators in guiding the diagnosis and treatment of PCa. The value of inflammation-related indicators in predicting the diagnosis and prognosis of PCa patients is now becoming clear.

Abstract
In the former work, the histogram was effectively used to improve the interference immunity of target velocity estimation based on the cross-spectrum. This paper proposes a new method to eliminate the bias introduced by the histogram and to further improve interference immunity. The equalization window is designed to preserve the cross-spectrum peaks while suppressing the interference peaks. All frequency points are compensated and accumulated to improve the interference immunity. Finally, the simulation and sea trial data verify the effectiveness of the proposed method in this paper.

Abstract
BACKGROUND Acute rejection (AR) is a major problem following liver transplantation (LT). Extracellular vesicles (EVs) are involved in various pathological processes including liver disease. Effect of EVs derived from bone marrow mesenchymal stem cells (BMSCs) on AR injury after orthotopic liver transplantation (OLT) in mice was investigated in this study. METHODS BMSCs and EVs were isolated and identified. OLT mouse model was established using Kamada's two cuff method and injected with EVs, followed by liver function detection and measurement of inflammatory cytokines (IL-10, IFN-γ, and TNF-α), M1 and M2 markers (TNF-α, iNOS, Retnla, and Arg1) were detected. KCs were cultured and treated with lipopolysaccharides. miR-22-3p expression was detected. The effect of EVs-shuttled miR-22-3p on Kupffer cells (KCs) polarization was studied. Binding relation of miR-22-3p and interferon regulatory factor 8 (IRF8) was verified. Effect of IRF8 on KCs polarization was verified. RESULTS BMSCs-EVs treatment enhanced liver function of OLT mice and alleviated AR and apoptosis, which were annulled after removing KCs. EVs induced KCs M2 polarization. Mechanically, EVs carried miR-22-3p into KCs, upregulated miR-22-3p in KCs and inhibited IRF8 expression. Upregulation of IRF8 in KCs inhibited the EVs-induced KCs M2 polarization. CONCLUSIONS BMSCs-EVs carry miR-22-3p into KCs and upregulate miR-22-3p, inhibit IRF8 expression, induce KCs M2 polarization and attenuate AR injury after LT.

Abstract
Bone metastasis is the most common complication responsible for most deaths in the advanced stages of prostate cancer (PCa). However, the exact mechanism of bone metastasis in PCa remains unelucidated. Herein, we explored the function and potential underlying mechanism of exosomal miR-375 in bone metastasis and tumor progression in PCa. This study revealed that miR-375 expression was markedly upregulated in advanced PCa with bone metastasis and metastatic PCa cell lines. Moreover, miR-375 showed high expression in PCa-derived exosomes and could be delivered to human mesenchymal stem cells (hMSCs) via exosomes. Mechanistically, miR-375 directly targeted DIP2C and upregulated the Wnt signaling pathway, thereby promoting osteoblastic differentiation in hMSCs. Furthermore, miR-375 promoted the proliferation, invasion, and migration of PCa cells in vitro and enhanced tumor progression and osteoblastic metastasis in vivo. Notably, the expression of miR-375, TCF-1, LEF-1, and β-catenin in was higher in PCa tissues with bone metastasis than in PCa tissues without bone metastasis and showed a continuous increase, whereas DIP2C, cyclin D1, and Axin2 showed an opposite expression pattern. In conclusion, our study suggests that cancer-derived exosomal miR-375 targets DIP2C, activates the Wnt signaling pathway, and promotes osteoblastic metastasis and PCa progression.

Abstract
INTRODUCTION T-cell immunoglobulin-3 (Tim-3) antibody drugs can treat malignant renal tumors but are expensive. To overcome this limitation, Lactococcus lactis host bacteria were used to express Tim-3 single-chain antibodies. METHODS The pLAN-CTB-Tim3scFv plasmid was constructed using molecular cloning technology and transformed into Lactococcus lactis. Expression and immune activity of proteins in the transformed bacteria were analyzed using Western blotting and enzyme-linked immunosorbent assay in vitro. A mouse subcutaneously transplanted tumor model of renal adenocarcinoma was constructed. The promoting effect of transformed bacteria on mouse spleen lymphocyte activation and their inhibitory effect on transplanted tumors were analyzed. RESULTS Transformed L. lactis NZ-CTB-Tim3scFv and NZ-Tim3scFv were successfully constructed. CTB-Tim3scFv secreted by NZ-CTB-Tim3scFv showed immunological activity. Compared with the NZ-Tim3scFv and NZ-Vector groups, the subgroups of splenic lymphocytes in the NZ-CTB-Tim3scFv group had a higher proportion of CD3+CD4+, CD3+CD8a+, and CD3+CD69+ cells. Ki67 and CD31 expression in the NZ-CTB-Tim3scFv group was significantly reduced. Tumor volume in the NZ-CTB-Tim3scFv group increased the least. DISCUSSION/CONCLUSION Secretion of CTB-Tim3scFv promoted the proliferation and activation of spleen lymphocytes and inhibited growth, cell proliferation, and angiogenesis of tumors. The proposed method is low cost and convenient with potential to become a new immunotherapy approach for renal-cell carcinoma.

Abstract
Background Residual dried blood spots (rDBS) from newborn screening programmes represent a valuable resource for medical research, from basic sciences, through clinical to public health. In Hong Kong, there is no legislation for biobanking. Parents’ view on the retention and use of residual newborn blood samples could be cultural-specific and is important to consider for biobanking of rDBS. Objective To study the views and concerns on long-term storage and secondary use of rDBS from newborn screening programmes among Hong Kong Chinese parents. Methods A mixed-method approach was used to study the views and concerns on long-term storage and secondary use of rDBS from newborn screening programmes among Hong Kong Chinese parents of children 0–3 years or expecting parents through focus groups (8 groups; 33 participants) and a survey (n = 1012, 85% mothers) designed with insights obtained from the focus groups. We used framework analysis to summarise the themes as supportive factors, concerns and critical arguments for retention and secondary use of rDBS from focus group discussion. We used multiple logistic regression to assess factors associated with support for retention and secondary use of rDBS in the survey. Results Both in focus groups and survey, majority of parents were not aware of the potential secondary use of rDBS. Overall secondary use of rDBS in medical research was well accepted by a large proportion of Hong Kong parents, even if all potential future research could not be specified in a broad consent. However parents were concerned about potential risks of biobanking rDBS including leaking of data and mis-use of genetic information. Parents wanted to be asked for permission before rDBS are stored and mainly did not accept an “opt-out” approach. The survey showed that parents born in mainland China, compared to Hong Kong born parents, had lower awareness of newborn screening but higher support in biobanking rDBS. Higher education was associated with support in rDBS biobanking only among fathers. Conclusion Long-term storage and secondary use of rDBS from newborn screening for biomedical research and a broad consent for biobanking of rDBS are generally acceptable to Hong Kong parents given their autonomy is respected and their privacy is protected, highlighting the importance of an accountable governance and a transparent access policy for rDBS biobanks.

Abstract
Background It is unclear whether genetic variants identified from single nucleotide polymorphisms (SNPs) strongly associated with coronary heart disease (CHD) in genome-wide association studies (GWAS), or a genetic risk score (GRS) derived from them, can help stratify risk of recurrent events in patients with CHD. Methods Study subjects were enrolled at the close-out of the LIPID randomised controlled trial of pravastatin vs placebo. Entry to the trial had required a history of acute coronary syndrome 3–36 months previously, and patients were in the trial for a mean of 36 months. Patients who consented to a blood sample were genotyped with a custom designed array chip with SNPs chosen from known CHD-associated loci identified in previous GWAS. We evaluated outcomes in these patients over the following 10 years. Results Over the 10-year follow-up of the cohort of 4932 patients, 1558 deaths, 898 cardiovascular deaths, 727 CHD deaths and 375 cancer deaths occurred. There were no significant associations between individual SNPs and outcomes before or after adjustment for confounding variables and for multiple testing. A previously validated 27 SNP GRS derived from SNPs with the strongest associations with CHD also did not show any independent association with recurrent major cardiovascular events. Conclusions Genetic variants based on individual single nucleotide polymorphisms strongly associated with coronary heart disease in genome wide association studies or an abbreviated genetic risk score derived from them did not help risk profiling in this well-characterised cohort with 10-year follow-up. Other approaches will be needed to incorporate genetic profiling into clinically relevant stratification of long-term risk of recurrent events in CHD patients.

Abstract
Immunotherapy and targeted therapy have been particularly effective in treating tumors of the urinary system; however, the mechanisms of the Wnt family of proteins in the tumorigenesis, development, and immune response of urinary system tumors are not fully understood. Here, we show that the Wnt family was extensively upregulated in and impacted the prognosis of patients with prostate adenocarcinoma (PRAD) and bladder urothelial carcinoma (BLCA). Moreover, the Wnt family correlated with the levels of infiltrating immune cells, including B cells, CD4 + T cells, CD8 + T cells, neutrophils, macrophages, and dendritic cells. The expression levels of Wnt family members were closely related to neoantigens, the mismatch repair system (MMRS) and DNA methyltransferases, and the mutation rate was generally low. Wnt family members are potential biomarkers for precision immunotherapy of urinary system tumors.

Abstract
PURPOSE To identify risk factors and potential predictors of erectile dysfunction (ED) in type-2 diabetes mellitus (T2DM) patients for early detection and treatment. METHODS A retrospective cohort was used to assess the clinical data of 105 diabetic patients with ED from May 2019 to April 2020 age-matched to 105 diabetic patients without ED. Potential risk factors that could contribute to ED were compared between the groups. Erectile function was evaluated using the International Index of Erectile Function-5 questionnaire. RESULTS There were higher rates of diabetic peripheral neuropathy (p = 0.036) and retinopathy (p < 0.001), longer duration of diabetes (p < 0.001), lower estimated glomerular filtration rate (p = 0.010) values, and higher uric acid (p < 0.001) and C-reactive protein (p = 0.001) levels in the ED group compared to the non-ED group. Multivariate logistic analysis identified uric acid, diabetic retinopathy, and T2DM course as independent predictors of diabetic ED. Diabetics with retinopathy and T2DM for ≥49 months were 3.028 and 3.860 times more likely to have ED, respectively. Uric acid values ≥392.5 μmol/L were associated with 18.638 times greater risk of having ED, though the values were within normal range. CONCLUSION In T2DM patients, higher uric acid (≥392.5 μmol/L), longer diabetes duration (≥49 months), and the presence of diabetic retinopathy were important and reliable predictors for diabetic ED. For patients who have high risk factors for developing ED, diligent screening and early treatment are necessary.

Abstract
Knowledge of asbestos-related diseases has been accumulating for over one hundred years as the industrial value of asbestos was recognised for the strength of its fibres and their resistance to destruction, resulting in increasing production and use until the multiple health effects have become apparent. Deposition in the lung parenchyma results in an inflammatory/progressively fibrotic response, with impaired gas exchange and reduced lung compliance ('asbestosis'), causing progressive dyspnoea and respiratory failure for which only palliation is indicated, although anti-fibrotic agents used for idiopathic usual interstitial pneumonitis remain to be evaluated. Benign pleural effusion, diffuse pleural fibrosis (occasionally with associated rolled atelectasis) and pleural plaques are the non-malignant pleural diseases that result from fibres reaching the pleura. But the main issues that led to the ban on asbestos in industry are those of malignancy: lung cancer, malignant mesothelioma (MM) of the pleura and MM of the peritoneum. Bronchogenic carcinoma risk from asbestos exposure is dose-dependent and multiplies the risk attributable to tobacco smoking. The principles of treatment are as for all cases of lung cancer. Low-dose computed tomography screening of exposed people can detect early-stage, non-small cell cancers, with improved survival. The amphibole varieties of asbestos are much more potent causes of MM than chrysotile, and the risk increases exponentially for 40-50 years following first exposure. As MM is non-resectable and poorly responsive to chemotherapy and radiotherapy, curative treatment is not possible and screening not justified.

Abstract
BACKGROUND Portal vein velocity (PVV) has shown reasonable correlation with the presence of portal hypertension in patients with cirrhosis. This study aims to evaluate the value of PVV for diagnosing clinically significant portal hypertension (CSPH) and predicting the risk of variceal hemorrhage (VH) in patients with hepatitis B virus (HBV)-related cirrhosis. MATERIAL AND METHODS A cohort of 166 consecutive adult patients with HBV-related cirrhosis was recruited in this retrospective study from two high-volume liver centers in China between April 2015 and April 2017. The performance of PVV and other non-invasive parameters for diagnosing CSPH and predicting risk of VH were studied. RESULTS PVV demonstrated the best performance for diagnosing CSPH (defined as an HVPG ≥10 mmHg) in patients with HBV-related cirrhosis among the included noninvasive predictors with the area under the receiver operating characteristic curve (AUC), specificity, and sensitivity of 0.745, 50%, and 93.5%, respectively. Other noninvasive markers, including APRI, AAR, LS, FIB-4, and diameter of portal vein, did not show sufficient performance with the AUCs of 0.565, 0.560, 0.544, 0.529, and 0.474, respectively. With regard to predicting the risk of VH (defined as an HVPG ≥12 mmHg), PPV also exhibited a moderate performance with an AUC of 0.762, which was superior to that of the aforementioned markers. By using two cutoff values of PVV to rule-out (11.65 cm/s) and rule-in (20.20 cm/s) CSPH, 30 (33.7%) patients showed definite results categories, with 23 (76.7%) patients were well classified and 7 (23.3%) were misclassified. Fifty-nine (66.3%) patients were with indeterminate results. By using PVV values of 13.10 cm/s and 21.40 cm/s to rule-out and rule-in HVPG ≥ 12mmHg, 34 (38.2%) patients has definite results, among whom 26 (76.5%) were well classified and 8 (23.5%) were misclassified. And 55 (61.8%) patients required further evaluation. CONCLUSION PPV is not good enough to serve as a non-invasive parameter for identifying CSPH and predicting risk of VH in patients with HBV-related cirrhosis.

Abstract
OBJECTIVE This study was performed to explore the effects of metabolic memory on diabetic erectile dysfunction (ED), especially the severity and response to treatment. METHODS Through medical records and follow-up by telephone, 67 patients meeting the criteria with a clinical diagnosis of ED and a diabetic history of more than 5 years were enrolled for erectile function analysis. They were divided into a glycemic control group, a glycemic non-control group and a metabolic memory group according to glycemic levels and treatments for diabetes in the past 5 years, and they were treated with phosphodiesterase type 5 (PDE5) inhibitors for 4 weeks. Erectile function and efficacy were assessed by the International Index for Erectile Function (IIEF), the Erection Hardness Score (EHS), and the Sexual Encounter Profile (SEP). RESULTS The patients in the glycemic control group performed better in erectile function than those in the other groups. The patients in the glycemic control group received a significantly greater score on both the EHS and the five domains of the IIEF than did the patients in the glycemic non-control group and the metabolic memory group (all P < .001). There were also statistically significant differences favoring the glycemic control group (P < .05) in SEP2 and SEP3 success rates. However, there were no significant differences between the metabolic memory group and the glycemic non-control group in these erectile function assessments (P > .05). Significant negative correlations were seen between HbA1c levels at the time of consultation and the scores on the IIEF-EF and the EHS (Pearson r-values of -0.338 with P = .005 and -0.273 with P = .025, respectively). HbA1c levels at the first diagnosis of diabetes mellitus (DM) were also significantly negatively correlated with scores on the IIEF-EF and the EHS with greater Pearson correlation coefficients (Pearson r-values of -0.478 with P < .001 and -0.392 with P = .001, respectively). Significant improvements on each of the erectile function assessments were observed among diabetic patients with ED, but no significant difference in efficacy was observed between each group. CONCLUSIONS The phenomenon of metabolic memory did have a significant influence on ED in men with diabetes, associated with the severity of ED but not the response to medical treatment. Early hyperglycemia exposure would have long-term disadvantageous effects on erectile function in diabetic patients with ED, which would be sustained even after the patients achieve better glycemic control. PATIENTS SUMMARY In this report, we looked at the erectile functions of 67 patients with a clinical diagnosis of ED and a diabetic history of more than 5 years. We found that early hyperglycemia exposure would have long-term disadvantageous effects on erectile function in diabetic patients with ED, which would be sustained even after the patients achieve better glycemic control. We further found that the effects were associated with the severity of ED but not the response to medical treatment in men with diabetes.

Abstract
The effectiveness and predictability of 2 different oral appliance (OA) designs to reduce the respiratory event index (REI) in moderate and severe obstructive sleep apnea (OSA) patients requires elucidation. The primary aim of the trial was to determine if 2 widely used midline-traction and bilateral-thrust OA designs differ in effectiveness to reduce the REI within a single test population categorized by OSA severity. Moderate and severe adult OSA patients, who were previously prescribed continuous positive airway pressure therapy (CPAP) but were dissatisfied with it (n = 56), were studied by home-polygraphy in a randomized crossover trial using either midline-traction with restricted mouth opening (MR) or bilateral thrust with opening permitted (BP) design OAs. OAs were used nightly for 4 wk (T2) followed by a 1-wk washout period, then 4 wk (T4) using the alternate OA. REI and oxygen saturation (SaO2) were primary outcomes, while predictability and efficacy comparison of the 2 OAs were secondary outcomes. Thirty-six participants had used MR and BP OAs during both 4-wk study legs. Twenty (55.6%) MR OA-using participants, 25 (69.4%) BP OA-using participants, and 16 (44.4%) participants using both OAs had significant REI reductions. Overall baseline (T0) median REI (interquartile range) of 33.7 (20.7-54.9) was reduced to 18.0 (8.5-19.4) at T2 and to 12.5 (8.2-15.9) at T4 (P < 0.001). Comparison of the 2 sequence groups' (MR-BP and BP-MR) REI showed the median differences between T0 and T2 and T4 were highly significant (P < 0.001). Regression analysis predicted about half of all users will have REIs between 8 and 16 after 2 mo. Baseline overjet measures >2.9 mm predicted greater OA advancement at T4. Mean and minimum SaO2 did not change significantly from T0 to T2 or T4. MR and BP OA designs similarly attenuated REI in moderate and severe OSA individuals who completed the 8-wk study protocol with greater REI reduction in those with severe OSA (ClinicalTrials.gov NCT03219034).

Abstract
Purpose Erectile dysfunction (ED) is one of the most common male-disease globally. Despite efforts to explain its pathogenesis, the molecular mechanisms of ED are still not well understood. Methods The microarray dataset GSE10804 was downloaded from the Gene Expression Omnibus (GEO) to find candidate genes in ED progression. After differentially expressed genes (DEGs) were identified, functional enrichment analysis was performed. In addition, a protein-protein interaction network (PPI) was established and module analysis was performed through the STRING and Cytoscape. Results and Conclusions A total of 618 DEGs were identified in all, containing 430 downregulated genes and 188 upregulated genes. The enriched functions and pathways of the DEGs include transcription from RNA polymerase II promoter, cell adhesion, calcium ion binding, receptor binding, Akt signaling pathway, receptor interaction, protein digestion, and absorption. We picked out twenty-five hub genes, with biological process (BP) analyses revealing that the genes were principally associated with cellular responses to amino acid stimuli, extracellular matrix structural constituent, collagen trimer, protein digestion and absorption, ECM-receptor interaction and PI3K-Akt signaling pathway. To sum up, DEGs and hub genes distinguished in this study not only help us understand the molecular mechanisms behind the carcinogenesis and progression of ED, but also play a part in the diagnosis and treatment of ED by providing candidate targets.

Abstract
BACKGROUND In developing countries, ambient sulfur dioxide (SO2) is a serious air pollutant concern, but there is no enough and consistent epidemiological evidence about its health effects on stroke hospitalization. METHODS We collected the daily air pollution data, meteorological data and number of daily hospital admissions for ischemic and hemorrhagic stroke, in Guangzhou from January 1st 2009 to December 31st 2014. Then we applied generalized additive model with a quasi-Poisson link to assess the relationship between short-term SO2 exposure and the total number of hospital admissions for ischemic and hemorrhagic stroke. In addition, we evaluated the effect of ambient SO2 by age (< 65 years and ≥ 65 years). RESULTS During the study period, a 24-h mean concentration of ambient SO2 of 27.82 μg/m3, a total of 58,473 ischemic stroke and 9167 hemorrhagic stroke hospital admissions hospital were recorded. Ambient SO2 was found to increase the risk for both ischemic and hemorrhagic stroke hospital admission in single pollutant model. The maximum value of percentage changes for ischemic and hemorrhagic stroke occurred in lag 0 day and lag 1 day, per 10 μg/m3 increase in SO2 concentrations was corresponded to a 1.27% (95% confidence interval (CI), 0.42-2.12%) and 1.55% (95%CI, 0.02-3.11%) increased risk, respectively. The association between SO2 and ischemic stroke hospitalization was robust to two pollutant model, but for hemorrhagic stroke it's partially weakened after adjusting for co-pollutants. The effect of ambient SO2 on ischemic stroke appeared to be greater for people < 65 years old, but null effect on hemorrhagic stroke was identified for both age groups. CONCLUSIONS We found short-term exposure to ambient SO2 may significantly increase the risks of hospitalization for ischemic stroke. The findings may contribute to a better understanding of the health effects of low-levels of SO2.

Abstract
The incidence of premature ejaculation (PE) has been on the rise over the years. Thus, significant research efforts have been directed toward understanding the pathogenesis and hence treatment of PE. Here, we performed a comprehensive analysis of the worldwide trends in research outputs in the field of PE. This study investigated the universal findings of previous PE studies and the trending issues surrounding the condition. We employed the Web of Science Core Collection for data collection. The Excel (2016) and CiteSpace IV were used for information analysis. The information was categorized using journal names, institutions, research frontiers, citation reports, regions/countries, and authors. A sum of 886 publications concerning PE between 2008 and 2018 were identified as of July 6, 2019. The highest number of publications was identified in the Journal of Sexual Medicine published. The United States of America (USA) had the highest number of publications and H-index value. The highest co-citations were from Waldinger MD. The most common keyword was 'drug treatment'. A steady pattern was observed for PE publications done between the period of 2008-2018. Thus, the USA is at the forefront of research on PE research. The interesting advanced research frontiers were drug treatment, circumcision, and sertraline.

Abstract
OBJECTIVE To explore the effects of exogenous hydrogen sulfide (H2S) on apoptosis of corpus cavernosum smooth muscle cells (CCSMCs) and erectile dysfunction (ED) in rats with bilateral cavernous nerve injury (BCNI). METHODS Twentyfour male SD rats were randomly divided into 3 groups (n=8):sham operation group, bilateral cavernous nerve injury group (BCNI group) and H2S intervention group (BCNI+NaHS group). In BCNI and BCNI+NaHS groups, BCNI was induced by clamp injury of the bilateral cavernous nerves, and the rats were subjected to daily intraperitoneal injection of normal saline and 100 μmol/kg NaHS solution for 4 weeks, respectively. After the treatment, the intracavernous pressure (ICP) and mean arterial pressure (MAP), ) of the rats were measured. Western blotting was used to detect the expressions of cystathionine β synthetase (CBS), cystathionine γ lyase (CSE), α-SMA, collagen-I, caspase-3, Bax and Bcl-2 in the penile cavernous tissue, and the expressions of CBS and CSE were also detected immunohistochemically. The ratio of cavernous smooth muscle to collagen was detected using Masson's Trichrome staining. The apoptosis level of CCSMC was detected by TUNEL + α-SMA immunofluorescence double staining. RESULTS After 4 weeks of treatment, the rats in BCNI+NaHS group showed a significantly higher ICP/MAP ratio than those in BCNI group (P < 0.05). The results of Masson's Trichrome staining showed that the ratio of cavernous smooth muscle/collagen was significantly higher in BCNI + NaHS group than in BCNI group (P < 0.05). Western blotting showed a significantly higher expression of α-SMA protein but a lower expression of collagen-I protein in BCNI + NaHS group than in BCNI group (P < 0.05). TUNEL+α-SMA immunofluorescence double staining revealed a significantly lower number of apoptotic CCSMCs in BCNI+NaHS group than in BCNI group (P < 0.05). Compared with those in BCNI group, the rats in BCNI+NaHS group had significantly decreased expressions of caspase-3 and Bax proteins (P < 0.05) with significantly enhanced Bcl-2 protein expression and an increased Bcl-2/Bax ratio (P < 0.05). The expressions of CBS and CSE were significantly lower in BCNI group than in the other two groups (P < 0.05). CONCLUSIONS Exogenous H2S enhance the expression of the classic apoptotic protein Bcl-2 and reduces apoptosis of CCSMC to improve the erectile function in rats with BCNI.

Abstract
AIM A nomogram model was developed to predict the histological subtypes of lung invasive adenocarcinomas (IAs) and minimally invasive adenocarcinomas (MIAs) that manifest as part-solid ground-glass nodules (GGNs). MATERIALS AND METHODS This retrospective study enrolled 119 patients with histopathologically confirmed part-solid GGNs assigned to the training (n=83) or testing cohorts (n=36). Radiomic features were extracted based on the unenhanced computed tomography (CT) images. R software was applied to process the qualitative and quantitative data. The CT features model, radiomic signature model, and combined prediction model were constructed and compared. RESULTS A total of 396 radiomic features were extracted from the preoperative CT images, four features including MaxIntensity, RMS, ZonePercentage, and LongRunEmphasis_angle0_offset7 were indicated to be the best discriminators to establish the radiomic signature model. The performance of the model was satisfactory in both the training and testing set with areas under the curve (AUCs) of 0.854 (95% confidence interval [CI]: 0.774 to 0.934) and 0.813 (95% CI: 0.670 to 0.955), respectively. The CT morphology of the lesion shape and diameter of the solid component were confirmed to be a significant feature for building the CT features model, which had an AUC of 0.755 (95% CI: 0.648 to 0.843). A nomogram that integrated lesion shape and radiomic signature was constructed, which contributed an AUC of 0.888 (95% CI: 0.82 to 0.955). CONCLUSIONS The radiomic signature could provide an important reference for differentiating IAs from MIAs, and could be significantly enhanced by the addition of CT morphology. The nomogram may be highly informative for making clinical decisions.

Abstract
Background Compassion has been identified as important for therapeutic relationships in clinical medicine however there have been few empirical studies looking at how compassion is expressed different contexts. The purpose of this study was to explore how context impacts perceptions and expressions of compassion in the intensive care unit and in palliative care. Methods This was an inductive qualitative study that employed sensitizing concepts from activity theory, realist inquiry, phenomenology and autoethnography. Clinicians working in intensive care units and palliative care services wrote guided field notes on their observations and experiences of how suffering and compassion were expressed in these settings. Data were analyzed using constructivist grounded theory. Results Fifty-eight field notes were generated, along with transcripts from three focus groups. Clinicians conceptualized, observed, and expressed compassion in different ways within different contexts. Patterns of compassion identified were relational, dispositional, activity-focused, and situational. A pattern language of compassion in healthcare was developed based on these findings. Conclusions Recognizing compassion as shifting patterns of diverse attitudes, behaviours, and relationships raises numerous questions as to how compassion can be developed, supported and recognized in different clinical settings.

Abstract
Purpose To develop and validate a computational model for estimating hepatic venous pressure gradient (HVPG) based on CT angiographic images, termed virtual HVPG, to enable the noninvasive diagnosis of portal hypertension in patients with cirrhosis. Materials and Methods In this prospective multicenter diagnostic trial (ClinicalTrials.gov identifier: NCT02842697), 102 consecutive eligible participants (mean age, 47 years [range, 21-75 years]; 68 men with a mean age of 44 years [range, 21-73 years] and 34 women with a mean age of 52 years [range, 24-75 years]) were recruited from three high-volume liver centers between August 2016 and April 2017. All participants with cirrhosis of various causes underwent transjugular HVPG measurement, Doppler US, and CT angiography. Virtual HVPG was developed with a three-dimensional reconstructed model and computational fluid dynamics. Results In the training cohort (n = 29), the area under the receiver operating characteristic curve (AUC) of virtual HVPG in the prediction of clinically significant portal hypertension (CSPH) was 0.83 (95% confidence interval [CI]: 0.58, 1.00). The diagnostic performance was prospectively confirmed in the validation cohort (n = 73), with an AUC of 0.89 (95% CI: 0.81, 0.96). Inter- and intraobserver agreement was 0.88 and 0.96, respectively, suggesting the good reproducibility of virtual HVPG measurements. There was good correlation between virtual HVPG and invasive HVPG (R = 0.61, P < .001), with a satisfactory performance to rule out (7.3 mm Hg) and rule in (13.0 mm Hg) CSPH. Conclusion The accuracy of a computational model of virtual hepatic venous pressure gradient (HVPG) shows significant correlation with invasive HVPG. The virtual HVPG also showed a good performance in the noninvasive diagnosis of clinically significant portal hypertension in cirrhosis. © RSNA, 2018 Online supplemental material is available for this article.

Abstract
Background and objectives: This retrospective study analysed a case series of subjects with citrin deficiency, and aims to present the molecular and clinical characterization of this disease in the Hong Kong Chinese population for the first time. Patients and Methods: Data from medical records of eighteen patients with citrin deficiency (years 2006–2015) were retrieved. Demographic data, biochemical parameters, radiological results, genetic testing results, management, and clinical outcome were collected and analysed. Results: Eighteen patients with diagnosis of citrin deficiency were recruited. All 18 patients carried at least one common pathogenic variant c.852_855delTATG in SLC25A13. Prolonged jaundice (neonatal intrahepatic cholestasis caused by citrin deficiency, NICCD) was the most common presenting symptom, in conjunction with elevated plasma citrulline, threonine, alkaline phosphatase, and alpha-fetoprotein levels. The abnormal biochemical parameters including liver derangement returned to normal range in most of the cases by 6 months of age after the introduction of a lactose-free formula. There were a few cases with atypical presentations. Two subjects did not present with NICCD, and were subsequently diagnosed later in life after their siblings presented with symptoms of citrin deficiency at one month of age and subsequently received a molecular diagnosis. One patient with citrin deficiency also exhibited multiple liver hemangioendotheliomas, which subsided gradually after introduction of a lactose-free formula. Only one patient from this cohort was offered expanded metabolic screening at birth. She was not ascertained by conducted newborn screening and was diagnosed upon presentation with cholestatic jaundice by 1 month of age. Conclusion: This is the first report of the clinical and molecular characterization of a large cohort of patients with citrin deficiency in Hong Kong. The presentation of this cohort of patients expands the clinical phenotypic spectrum of NICCD. Benign liver tumors such as hemangioendotheliomas may be associated with citrin deficiency in addition to the well-known association with hepatocellular carcinoma. Citrin deficiency may manifest in later infancy period with an NICCD-like phenotype. Furthermore, this condition is not always ascertained by expanded newborn metabolic screening testing.

Novel Intra-Procedural Distensibility Measurement Accurately Predicts Immediate Outcome of Pneumatic Dilatation for Idiopathic Achalasia. Am J Gastroenterol 2018; 113:205-212.

Abstract
OBJECTIVES Often 2-3 graduated pneumatic dilatations (PD) are required to treat achalasia as there is no current intra-procedural predictor of clinical response. Distensibility measurements using functional lumen imaging probe (FLIP) may provide an intra-procedural predictor of outcome. Our aim was to determine the optimal criterion for esophagogastric junction (EGJ) distensibility measurements during PD that predicts immediate clinical response. METHODS EGJ distensibility was prospectively measured using FLIP immediately pre- and post-PD. The EGJ distensibility index (EGJ-DI) was defined as a ratio of the narrowest cross-sectional area and the corresponding intra-bag pressure at 40 ml distension. Immediate and short-term clinical responses were defined as Eckardt score ≤3 assessed 2 weeks Post-PD and at 3-month follow-up, respectively. RESULTS In 54 patients, we performed thirty-seven 30 mm; twenty 35 mm and six 40 mm PDs. The short-term response rate to the graded PD was 93% (27/29) in newly diagnosed achalasia; 87% (13/15) and 70% (7/10) in those who had relapsed after previous PD and Heller's Myotomy, respectively. Among those demonstrating an immediate response, EGJ-DI increased by an average of 4.5 mm2/mmHg (95% CI (3.5, 5.5) (P<0.001). Within-subject Δ EGJ-DI was highly predictive of immediate clinical response with AUROC of 0.89 (95% CI [0.80, 0.98], P<0.001). An increment in EGJ-DI of 1.8 mm2/mmHg after a single PD predicts an immediate response with an accuracy of 87%. CONCLUSIONS FLIP-measured Δ EGJ-DI is a novel intra-procedural tool that accurately predicts immediate clinical response to PD in achalasia. This technique may potentially dictate an immediate mechanism to "step-up" dilator size within a single endoscopy session.

Abstract
Introduction Continuous development of cell traction force can regulate cell migration on various extracellular matrixes in vivo. However, the topographical effect on traction force is still not fully understood. Methods Micropost sensors with parallel guiding gratings were fabricated in polydimethylsiloxane to track the cell traction force during topographical guidance in real time. The force distributions along MC3T3-E1 mouse osteoblasts were captured every minute. The traction force in the leading, middle, and trailing regions was monitored during forward and reversed cell migration. Results The traction force showed periodic changes during cell migration when the cell changed from elongated to contracted shape. For cell migration without guiding pattern, the leading region showed the largest traction force among the three regions, typically 5.8 ± 0.8 nanonewton (nN) when the cell contracted and 7.1 ± 0.5 nN when it elongated. During guided cell migration, a lower traction force was obtained. When a cell contracted, the trailing traction force was 4.1 ± 0.4 for non-guided migration and 2.2 ± 0.2 nN for guided migration. As a cell became elongated, the trailing traction force was 6.0 ± 0.5 nN during non-guided migration and 4.8 ± 0.3 nN under guidance. When a cell reversed its migration direction, the magnitudes of the traction force from the leading to the trailing regions also flipped. Conclusion The cell traction force is continuously influenced by topographical guidance, which determines cell migration speed and direction. These results of cell traction force development on various topographies could lead to better cell migration control using topotaxis.

Abstract
BACKGROUND AND AIMS Several studies were conducted to explore the prognostic significance of platelet to lymphocyte ratio (PLR) in hepatocellular carcinoma (HCC), however, contradictory results across most reports were documented. To this end, we present a systematic review that aims to summarize the prognostic significance of PLR in patients with HCC. RESULTS A total of 10 studies involving a total of 2,315 patients were identified. The Newcastle-Ottawa Quality Assessment Scale (NOS) of each included study was greater than or equal to 5. The results indicated that high PLR was significantly associated with a worse OS when compared to the low PLR (HR = 1.60, 95% CI = 1.23-2.08, p = 0.0005; I2 = 88%, p < 0.00001). Similar results were detected in the subgroup analysis of the analysis model, cut-off value, ethnicity, sample size and therapy. However, no obvious correlation between the PLR and DFS/RFS in patients with HCC was observed (HR = 1.21, 95% CI = 0.87-1.67, p = 0.26; I2 = 61%, p = 0.07). MATERIALS AND METHODS A complete literature search in the PubMed, Cochrane Library and Embase database was performed. Retrospective and prospective studies focusing on the role of PLR on the prognosis in HCC were all deemed as "suitable" for our scope. The endpoints determined were: the overall survival (OS), disease-free survival (DFS), recurrence-free survival (RFS) and the progress free survival (PFS). CONCLUSIONS The study revealed that high PLR is an unfavorable predictor of OS in patients with HCC, and high PLR is a promising prognostic biomarker for HCC, especially for patients in Asia.

Abstract
INTRODUCTION No universal expanded newborn screening service for inborn errors of metabolism is available in Hong Kong despite its long history in developed western countries and rapid development in neighbouring Asian countries. To increase the local awareness and preparedness, the Centre of Inborn Errors of Metabolism of the Chinese University of Hong Kong started a private inborn errors of metabolism screening programme in July 2013. This study aimed to describe the results and implementation of this screening programme. METHODS We retrieved the demographics of the screened newborns and the screening results from July 2013 to July 2016. These data were used to calculate quality metrics such as call-back rate and false-positive rate. Clinical details of true-positive and false-negative cases and their outcomes were described. Finally, the call-back logistics for newborns with positive screening results were reviewed. RESULTS During the study period, 30 448 newborns referred from 13 private and public units were screened. Of the samples, 98.3% were collected within 7 days of life. The overall call-back rate was 0.128% (39/30 448) and the false-positive rate was 0.105% (32/30 448). Six neonates were confirmed to have inborn errors of metabolism, including two cases of medium-chain acyl-coenzyme A dehydrogenase deficiency, one case of carnitine-acylcarnitine translocase deficiency, and three milder conditions. One case of maternal carnitine uptake defect was diagnosed. All patients remained asymptomatic at their last follow-up. CONCLUSION The Centre of Inborn Errors of Metabolism has established a comprehensive expanded newborn screening programme for selected inborn errors of metabolism. It sets a standard against which the performance of other private newborn screening tests can be compared. Our experience can also serve as a reference for policymakers when they contemplate establishing a government-funded universal expanded newborn screening programme in the future.

Abstract
BACKGROUND Myocardial infarction is one of the most common causes of death, and the number of individuals at risk is increasing. A rapid and accurate differential diagnosis of myocardial infarction is crucial for timely interventions and for improvement of the prognosis. However, it is difficult to achieve using current methods. To better manage this condition, improved tools for risk prediction, including more accurate biomarkers, are needed. METHODS We studied the expression of microRNA-539 (miR-539) and of MEK protein using a rat model of myocardial infarction. RESULTS The results of our experiments demonstrated an increase in the expression of miR-539 and a decrease in the expression of MEK. Furthermore, we observed that miR-539 inhibited the expression of MEK through targeting of the 3'UTR of MEK; this led not only to suppressed proliferation but also to apoptosis and autophagy of H9C2 cells. CONCLUSION Overexpression of miR-539 plays a role in the degree of myocardial infarction. On the basis of our results, we conclude that miR-539 may be a potential therapeutic target for myocardial infarction.

Abstract
BACKGROUND Functional variants in the interleukin-6 receptor gene (IL6R) are associated with asthma risk. We hypothesized that genes co-expressed with IL6R might also be regulated by genetic polymorphisms that are associated with asthma risk. The aim of this study was to identify such genes. METHODS To identify genes whose expression was correlated with that of IL6R, we analyzed gene expression levels generated for 373 human lymphoblastoid cell lines by the Geuvadis consortium and for 38 hematopoietic cell types by the Differentiation Map Portal (DMAP) project. Genes correlated with IL6R were then screened for nearby single nucleotide polymorphisms (SNPs) that were significantly associated with both variation in gene expression levels (eSNPs) and asthma risk. RESULTS We identified 90 genes with expression levels correlated with those of IL6R and that also had a nearby eSNP associated with disease risk in a published asthma GWAS (N = 20 776). For 16 (18%) genes, the association between the eSNP and asthma risk replicated with the same direction of effect in a further independent published asthma GWAS (N = 27 378). Among the top replicated associations (FDR < 0.05) were eSNPs for four known (IL18R1, IL18RAP, BCL6, and STAT6) and one putative novel asthma risk gene, stomatin-like protein 2 (STOML2). The expression of STOML2 was negatively correlated with IL6R, while eSNPs that increased the expression of STOML2 were associated with an increased asthma risk. CONCLUSION The expression of STOML2, a gene that plays a key role in mitochondrial function and T-cell activation, is associated with both IL-6 signaling and asthma risk.
