Abstract
BACKGROUND Bladder, kidney and prostate cancers make significant contributors to cancer burdens. Exploring their cross-country inequalities may inform equitable strategies to meet the 17 sustainable development goals before 2030. METHODS We analyzed age-standardized disability-adjusted life-years (ASDALY) rates for the three cancers based on Global Burden of Diseases Study 2019. We quantified the inequalities using slope index of inequality (SII, absolute measure) and concentration index (relative measure) associated with national sociodemographic index. RESULTS Varied ASDALY rates were observed in the three cancers across 204 regions. The SII decreased from 35.15 (95% confidence interval, CI: 29.34 to 39.17) in 1990 to 15.81 (95% CI: 7.99 to 21.79) in 2019 for bladder cancers, from 78.94 (95% CI: 75.97 to 81.31) in 1990 to 59.79 (95% CI: 55.32 to 63.83) in 2019 for kidney cancer, and from 192.27 (95% CI: 137.00 to 241.05) in 1990 to - 103.99 (95% CI: - 183.82 to 51.75) in 2019 for prostate cancer. Moreover, the concentration index changed from 12.44 (95% CI, 11.86 to 12.74) in 1990 to 15.72 (95% CI, 15.14 to 16.01) in 2019 for bladder cancer, from 33.88 (95% CI: 33.35 to 34.17) in 1990 to 31.13 (95% CI: 30.36 to 31.43) in 2019 for kidney cancer, and from 14.61 (95% CI: 13.89 to 14.84) in 1990 to 5.89 (95% CI: 5.16 to 6.26) in 2019 for prostate cancer. Notably, the males presented higher inequality than females in both bladder and kidney cancer from 1990 to 2019. CONCLUSIONS Different patterns of inequality were observed in the three cancers, necessitating tailored national cancer control strategies to mitigate disparities. Priority interventions for bladder and kidney cancer should target higher socioeconomic regions, whereas interventions for prostate cancer should prioritize the lowest socioeconomic regions. Additionally, addressing higher inequality in males requires more intensive interventions among males from higher socioeconomic regions.

Abstract
Normally, only noncentrosymmetric structure of the materials can potentially be piezoelectric. Thus, it is limited in the field of piezoelectricity for the centrosymmetric structure of the material. In this work, the performance of piezoelectricity is successfully achieved from centrosymmetric SrFeO3- x by modulating oxygen vacancies, which have a surface piezoelectric potential up to 93 mV by using Kelvin-probe force microscopy (KPFM). Moreover, the piezoelectric effects of SrFeO3- x are also evaluated by piezoelectric catalytic effect and density functional theory calculations (DFT). The results show that the piezo-catalytic degradation of tetracycline reaches 96% after 75 min by ultrasonic mechanical vibration and the production of H2 O2 by SrFeO3- x piezoelectric synthesis could reach 1821 µmol L-1 . In addition, the DFT results indicate that the intrinsic effect of oxygen vacancies effectively promotes the adsorption and activation of O2 and H2 O as well as intermediates and improves the piezoelectric catalytic activity. This work provides an effective basis for realizing the piezoelectricity of centrosymmetric materials and regulating the development of piezoelectric catalytic properties.

Abstract
Cadmium (Cd), an environmental contaminant, can result in placental non-selective autophagy activation and fetal growth restriction (FGR). However, the role of placental lipophagy, a selective autophagy, in Cd-induced FGR is unclear. This work uses case-control study, animal experiments and cultures of primary human placental trophoblast cells to explore the role of placental lipophagy in Cd-induced FGR. We found association of placental lipophagy and all-cause FGR. Meanwhile, pregnancy Cd exposure induced FGR and placental lipophgay. Inhibition of placental lipophagy by pharmacological and genetic means (Atg5-/- mice) exacerbated Cd-caused FGR. Inversely, activating of placental lipophagy relieved Cd-stimulated FGR. Subsequently, we found that activation of Atg5-dependent lipophagy degrades lipid droplets to produce free cholesterol, and promotes placental progesterone (P4) synthesis. Gestational P4 supplementation significantly reversed Cd-induced FGR. Altogether, activation of Atg5-dependent placental lipophagy ameliorates Cd-induced FGR.

Abstract
A 49-year-old woman with a rare autoimmune hematological disease, Evans syndrome, was admitted to the authors' hospital with immune reconstitution inflammatory syndrome-like reconstitution syndrome after effective antifungal therapy for cryptococcal meningitis. She initially improved after receiving corticosteroid treatment; after prednisone was tapered, her clinical presentation and brain imaging deteriorated but finally improved with the addition of thalidomide. Immune reconstitution inflammatory syndrome-like reconstitution syndrome is a rare complication in cryptococcal meningitis patients receiving immunosuppressive therapy. Thalidomide can be given in addition to corticosteroid therapy to effectively control the paradoxical inflammatory response and improve clinical outcomes.

Abstract
Traditional SrTiO3 (STO) materials have high brittleness and poor deformation resistance. In this work, macroscopically flexible iron-doped SrTiO3 (SFTO) nanofibrous membranes were prepared by electrospinning and calcination, which can be easily isolated and can maintain integrity to recycle as photocatalysts. Moreover, the SFTO nanofibrous membranes showed enhanced photocatalytic performance under strong acids (pH = 2) and strong alkalis (pH = 12). The SFTO nanofibrous membranes increased the catalytic rate of Congo red (CR) dye by about 10 times in visible light. The mechanism of photocatalytic activity enhancement was discussed by the combined effects of hydroxyl radicals and superoxide radicals. The successful preparation of SFTO nanofibrous membranes has offered a simple and economical approach to photocatalysis as well as environmental remediation.

Abstract
Bulk Bi0.5Sr0.5Fe0.5Cr0.5O3 (BSFCO) is a new compound comprising the R3c structure. The structural, magnetic property and exchange bias (EB) details are investigated. The material was in the super-paramagnetic (SP) state at room temperature. Exchange bias usually occurs at the boundary between different magnetic states after field cooling (HFC) acts on the sample. Here the result shows that changing HFC from 1 to 6 T reduces the HEB value by 16% at 2 K at the same time. Meanwhile, HEB diminishes as the ferromagnetic layer thickness increases. The variation of (the thickness of ferromagnetic layer) tFM with the change of HFC leads to the tuning of HEB by HFC in BSFCO bulk. These effects are obviously different from the phenomenon seen in other oxide types.

Abstract
Acquiring adsorbents capable of effective radioiodine capture is important for nuclear waste treatment; however, it remains a challenge to develop porous materials with high and reversible iodine capture. Herein, we report a porous self-assembly constructed by a cup-shaped PdII complex through intermolecular π···π interactions. This self-assembly features a cubic structure with channels along all three Cartesian coordinates, which enables it to efficiently capture iodine with an adsorption capacity of 0.60 g g-1 for dissolved iodine and 1.81 g g-1 for iodine vapor. Furthermore, the iodine adsorbed within the channels can be readily released upon immersing the bound solid in CH2Cl2, which allows the recycling of the adsorbent. This work develops a new porous molecular material promising for practical iodine adsorption.

Abstract
PURPOSE Postoperative pain is one of the most common postoperative complications, and improper management not only adds to patient suffering but also affects patients' recovery. In this study, we measured patients' postoperative pain to understand the status of patients after surgery and to identify factors influencing postoperative pain. DESIGN A descriptive and cross-sectional study METHODS: This survey was conducted at a large tertiary hospital in Chengdu, Sichuan Province. A total of 655 postoperative inpatients were included. The survey was conducted using the Chinese version of the Houston Pain Outcome Instrument. General patient data, pain management-related factors, and the pain management index were used to survey risk factors. We used t-tests and ANOVA for univariate analysis of each pain outcome category to explore the association with the predictor variables. Then, those variables with a significance level of 0.05 on univariate analysis were entered into multivariable regression analysis to identify parsimonious subsets of independent risk factors. FINDINGS In this survey, 58.7% of patients experienced moderate to severe pain in the 24-hour postoperative period, and 33.6% of patients had moderate to severe average pain over the 24-hour postoperative period. The postoperative pain impact scores on patient mood, somatic function, patient satisfaction with postoperative pain management, and pain education were 3.5 ± 2.1, 4.3 ± 3.1, 8.9 ± 1.4 and 8.2 ± 1.8, respectively. The pain management index, surgery type, insurance, and pain assessment of nurse were influential factors of postoperative pain intensity. Age, ethnicity, insurance, surgery type, patents' knowledge of pain, and pain assessment of the nurse affected the patients' postoperative physiological function (F = 3.822, R2 = 0.065, P = .000). In addition, area of residence and physician attitudes affected the outcomes of patient satisfaction with pain management (F = 26.652, R2 = 0.259, P = .000). CONCLUSIONS The incidence of moderate to severe pain in post-surgical patients remains high, and postoperative pain affects patients physically and psychologically. Special attention should be given to patients with lower income and literacy levels.

Abstract
OBJECTIVE To construct and verify a key gene signature of the basement membrane of prostate cancer (PCa) to predict the progression and biochemical recurrence of the malignancy after radical prostatectomy. METHODS Based on the PCa-related transcriptome, gene mutation and clinical data from the Cancer Genome Atlas Project (TCGA) database, we analyzed the differentially expressed genes (DEG) related to the basement membrane in the PCa and adjacent normal prostate tissues, and subjected them to GO function enrichment and KEGG pathway enrichment analyses. We identified prognosis-related genes from the DEGs and analyzed their mutations. According to the follow-up data and biochemical recurrence after prostatectomy, we established a prognostic risk scoring model, verified its accuracy using the Gene Expression Omnibus (GEO) database, and performed survival analysis, principal component analysis (PCA), independent prognostic analysis and ROC curve analysis of the model. We constructed a protein-protein interaction network after verifying the correctness of the model by immunohistochemistry. We also established a nomogram and tested its accuracy using ROC and calibration curves. RESULTS Totally, 85 DEGs were identified, among which 18 were up-regulated and 67 down-regulated. The prognostic risk scoring model was established with 11 of the genes. The risk of biochemical recurrence PCa was significantly higher in the high-risk than in the low-risk group (HR: 3.51, 95% CI: 2.32-5.32, P < 0.01), which was verified with the GEO database data (P < 0.01). In addition, the patients in the high-risk group were older with higher clinical T-stage, higher Gleason score, higher positive rate, larger numbers of positive lymph nodes, and a larger proportion of residual tumors than those in the low-risk group (P < 0.05). The nomogram constructed with the patients' age, pN, pT and cT stages, Gleason score and prognostic risk score manifested that the area under the ROC curve was higher than the other predictors. The calibration chart showed consistency of the predicted outcomes to the actual results. CONCLUSION A prognostic risk scoring model of basement membrane-related genes and an effective nomogram were successfully constructed, which can predict the risk of biochemical recurrence in PCa patients after radical prostatectomy.

Abstract
OBJECTIVE To discuss the clinical diagnosis and treatment of extragonadal germ cell tumor. METHODS We analyzed the clinical data on a case of extragonadal germ cell tumor diagnosed and treated in the General Hospital of Eastern Theater Command and reviewed the relevant literature. RESULTS The patient was initially diagnosed with retroperitoneal tumor and treated by resection of the tumor together with the left kidney due to the large volume of the tumor, which was complicated by pancreatic injury. Postoperative pathology showed it to be extragonadal germ cell malignancy. Postoperative examination revealed space-occupying lesion in the left testis, with serum alpha fetoprotein (AFP), human chorionicgonadotropin (hCG) and lactate dehydrogenase (LDH) negative, followed by stage-two resection of the left testis, which was pathologically shown with testicular seminoma. The patient received 7 courses of cisplatin, etoposide bleomycin (PEB) regimen and was followed up for 8 years, which found no recurrence or metastasis, and the patient fathered no child during the postoperative follow-up. CONCLUSION For patients with a history of cryptorchidism and tumors located in the central axis, special attention should be paid to physical examination of the testes, testicular ultrasonography, and determination of AFP and other indicators to identify gonadal tumor metastasis. And if so, radiotherapy and chemotherapy can be considered first to reduce surgical complications and achieve accurate management.

Abstract
To explore the brain volume (BV) changes of HIV-negative and non-transplant cryptococcal meningitis (CM) in one year after initial therapy. Case data were collected from 78 CM patients who underwent magnetic resonance imaging (MRI) scanning at least 3 times in one-year interval after initial therapy. The assessment of BV was measured by a non-commercial software, uAI Research Portal. Linear mixed model was used to investigate the association between clinical characteristics and the changes of BV. Longitudinal study showed a decrease in total brain volume (-4.65 cm3, p = 0.005), regional brain volume including white matter (-2.86 cm3, p = 0.031) and basal ganglia (-0.25 cm3, p = 0.007), and an increase in cerebrospinal fluid (CSF) volume (3.58 cm3, p = 0.013) in CM patients in one year after initial therapy. Ventricular volume in patients with ventriculoperitoneal shunts (VPS) was lower than that in patients without VPS (-7.5 cm3, p < 0.05). Ventricular volume in patients with post-infectious inflammatory response syndrome (PIIRS) was larger than that in patients without PIIRS (7.1 cm3, p < 0.01). In addition, temporal lobe atrophy was associated with corticosteroid therapy (-6.8 cm3, p < 0.01). The present study suggested that brain atrophy, especially regional BV decrease, could happen in the HIV-negative and non-transplant CM patients over a one-year interval.

Abstract
OBJECTIVES To compare the epidemiologic, clinical, laboratory, and imaging features, and outcomes in patients with Cryptococcus gattii meningitis (CGM) and Cryptococcus neoformans meningitis (CNM). METHODS We performed a retrospective study of HIV-negative patients with CGM and CNM (2015-2021) distinguished by metagenomic next-generation sequencing in cerebrospinal fluid in South China. RESULTS 81 patients (17 CGM, 64 CNM) were enrolled (72.8% male, median age 49 years, range 21-77 years), and CGM patients were younger (median, 43 vs 53 years, p = 0.005). Of 17 CGM, VGI and VGII accounted for 70.6% and 29.4%, respectively. CGM patients had less underlying diseases (7/17 [41.2%] vs 48/64 [75%], p=0.018) and focal neurologic deficit (3/17 [17.6%] vs 35/64 [54.7%], p = 0.022), had higher intracranial pressure (15/17 [88.2%] vs 25/64 [39.1%], p=0.002), more meningeal enhancement (14/17 [82.4%] vs 32/64 [50%], p = 0.034), less parenchymal involvement (median, 1 vs 3, p = 0.018), more lung cryptococcomas (6/12 [50%] vs 6/47 [12.8%], p = 0.014), faster CSF fungal clearance (p = 0.004), less complications (median, 1 vs 3, p < 0.001), and more favorable outcomes (16/17 [94.1%] vs 41/64 [64.1%], p =0.035). CONCLUSIONS This study demonstrated that species identification helps to guide therapy and predict outcomes.

Abstract
Objectives: To evaluate the role of pancreas multidisciplinary team(MDT) clinic in the diagnosis of pancreatic diseases,patient compliance with MDT advice,and the impact of MDT on the postoperative survival of patients with pancreatic cancer. Methods: The study included 927 patients(554 males,373 females,aged (58.1±13.3)years (range: 15 to 89 years)) that had visited the pancreas MDT clinic of Zhongshan Hospital from May 2015 to December 2021,and 677 patients(396 males, 281 females, aged (63.6±8.9)years(range: 32 to 95 years)) who underwent radical surgery and with pathologically confirmed pancreatic adenocarcinoma from January 2012 to December 2020,of whom 79 patients had attended the pancreas MDT. The clinical and pathological data were collected and analyzed retrospectively. Diseases were classified in accordance with 2010 WHO classification of tumors of the digestive system and usual clinical practices. The Kaplan-Meier method was used for drawing the survival curve and calculating the survival rate. The univariate analysis was done by Log-rank test and the multivariate analysis was done by COX proportional hazards model. Survival rates were compared using χ2 test. Results: Among the 927 patients that had visited the MDT clinic,233 patients(25.1%) were referred due to undetermined diagnosis. A direct diagnosis was made in 109 cases (46.8%,109/233) by the MDT clinic, of which 98 were consistent with the final diagnosis,resulting in an accuracy of 89.9%(98/109). The direct diagnosis rate in the recent years(36.6%(41/112),from June 2019 to December 2021) decreased compared to that in the previous years(56.2%(68/121),from May 2015 to May 2019),yet the accuracy in the recent years(90.2%,37/41) was basically the same as before (89.7%,61/68). The rate of compliance of the entire cohort was 71.5%(663/927), with the compliance rate in the recent two and a half years(81.4%,338/415) remarkably higher than that in the previous four years(63.4%,325/512). Patients with pancreatic cancer that attended the MDT exhibited a trend toward longer median postoperative survival than patients that did not attend the MDT,but the difference was not statistically significant(35.2 months vs.30.2 months,P>0.05). The 1-year and 3-year survival rates of patients that attended the MDT were significanly higher than patients that did not attend the MDT(88.6% vs. 78.4%,P<0.05;32.9% vs. 21.9%,P<0.05,respectively),but the 5-year survival rate was not statistically different(7.6% vs. 4.8%,P>0.05). Conclusions: The pancreas MDT clinic is an accurate and convenient way to diagnose intractable pancreatic diseases,and in the recent years the patients' compliance rate with MDT advice has increased. Pancreatic cancer patients that have attended the MDT have higher 1-year and 3-year postoperative survival rates,but the long-term survival benefits of MDT still needs to be proved by clinical studies on a larger scale.

Abstract
OBJECTIVE To evaluate effectiveness of self-designed adjustable cannulated screw guide, and to provide an effective auxiliary tool for inverted triangular arrangement of compression cannulated screws in clinical treatment for transcervical femoral neck fractures. METHODS The sketch of instrument was drawn with Solidworks software, and physical product was obtained after production. The data were obtained by Mimics software. Combined with the guide, it was first used on 22 cadaveric bones, 22 dry cadaveric bones, including 12 males and 10 females. Then the distribution of guide pins was evaluated by X-ray film. The anatomical size and screw distance of femoral head and neck were measured in different ways, and statistically compared. From January 2018 to June 2020, 45 hospitalized patients with femoral neck fracture were selected and divided into new guide group (22 patients) and free hand nail group (23 patients) according to whether the instrument was used or not. The clinical data and operation conditions between two groups were recorded and compared. RESULTS The anatomical data of X-ray, three-dimensional and physical measurement were basically the same, whlie had no difference (P>0.05). There was no significant difference between physical measurement and three-dimensional measurement (P>0.05). The distance between screws and needle entry point was designed as an isosceles triangle(r=0.992 8, P<0.000 1), but due to the existence of femoral anteversion and torsion angle, it was an approximate isosceles triangle in the femoral neck (r=0.824 1, P<0.000 1). The patients between two groups were followed up for an average of 2 years. There was no significant difference in the number of fluoroscopy and puncture between new guide group and free hand nail group(P>0.05). The screw parallelism was better and operation time was shorter which had statistically difference(P<0.05). However, there was no significant difference in final Harris score and incidence of complications between two groups(P>0.05). CONCLUSION Self-made femoral neck cannulated screw guide combined with preoperative planning of Mimics software is conducive to placement of inverted triangular arrangement of cannulated screws, but it still needs to be improved and followed up in the later large-scale use.

Abstract
In Escherichia coli, transcription-translation coupling is mediated by NusG. Although chloroplasts are descendants of endosymbiotic prokaryotes, the mechanism underlying this coupling in chloroplasts remains unclear. Here, we report transcription-translation coupling through AtNusG in chloroplasts. AtNusG is localized in chloroplast nucleoids and is closely associated with the chloroplast PEP complex by interacting with its essential component PAP9. It also comigrates with chloroplast ribosomes and interacts with their two components PRPS5 (uS5c) and PRPS10 (uS10c). These data suggest that the transcription and translation machineries are coupled in chloroplasts. In the atnusg mutant, the accumulation of chloroplast-encoded photosynthetic gene transcripts, such as psbA, psbB, psbC and psbD, was not obviously changed, but that of their proteins was clearly decreased. Chloroplast polysomic analysis indicated that the decrease in these proteins was due to the reduced efficiency of their translation in this mutant, leading to reduced photosynthetic efficiency and enhanced sensitivity to cold stress. These data indicate that AtNusG-mediated coupling between transcription and translation in chloroplasts ensures the rapid establishment of photosynthetic capacity for plant growth and the response to environmental changes. Therefore, our study reveals a conserved mechanism of transcription-translation coupling between chloroplasts and E. coli, which perhaps represents a regulatory mechanism of chloroplast gene expression. This study provides insights into the underlying mechanisms of chloroplast gene expression in higher plants.

Abstract
PURPOSE The introduction of intraoperative computed tomography and image-guided navigation have demonstrated some advantages for the correction of midfacial post-traumatic deformities. However, these methods still do not achieve satisfactory results. The authors sought to describe a novel method for the precise correction of complex midfacial post-traumatic deformities using three-dimensional printing customized surgical guides. METHODS Ten patients with midfacial post-traumatic deformities admitted between January 15, 2018 and August 20, 2020 were included. To design the surgical guide for each patient, preoperative planning and simulation datasets were used as a virtual template. Each surgical guide comprised three-dimensional printing cutting guides and customized titanium plates to guide the osteotomy and repositioning of the fracture fragments intraoperatively. Reduction and fixation were confirmed by intraoperative navigation. Postoperative deviation chromatography analysis and clinical examination were conducted to evaluate the surgical outcome. All operations were successfully performed. RESULTS The average difference between the virtual plans and postoperative results was less than 1.5 mm. The 3- to 6-month follow-up evaluation demonstrated that symptoms were alleviated, and postoperative function and esthetics improved considerably. CONCLUSIONS Three-dimensional-printed customized surgical guides can accurately and effectively transfer the virtual surgical plan to the patient and could be considered an ideal and valuable option for this potentially complicated procedure.

Abstract
AtRsmD was recently demonstrated to be a chloroplast 16S rRNA methyltransferase (MTase) for the m2G915 modification in Arabidopsis. Here, its function of AtRsmD for chloroplast development and photosynthesis was further analyzed. The AtRsmD gene is highly expressed in green photosynthetic tissues. AtRsmD is associated with the thylakoid in chloroplasts. The atrsmd-2 mutant exhibited impaired photosynthetic efficiency in emerging leaves under normal growth conditions. A few thylakoid lamellas could be observed in the chloroplast from the atrsmd-2 mutant, and these thylakoids were loosely organized. Knockout of the AtRsmD gene had minor effects on chloroplast ribosome biogenesis and RNA loading on chloroplast ribosomes, but it reduced the amounts of chloroplast-encoded photosynthesis-related proteins in the emerging leaves, for example, D1, D2, CP43, and CP47, which reduced the accumulation of the photosynthetic complex. Nevertheless, knockout of the AtRsmD gene did not cause a general reduction in chloroplast-encoded proteins in Arabidopsis grown under normal growth conditions. Additionally, the atrsmd-2 mutant exhibited more sensitivity to lincomycin, which specifically inhibits the elongation of nascent polypeptide chains. Cold stress exacerbated the effect on chloroplast ribosome biogenesis in the atrsmd-2 mutant. All these data suggest that the AtRsmD protein plays distinct regulatory roles in chloroplast translation, which is required for chloroplast development and chloroplast function.

Abstract
Photoperiod/temperature-sensitive genic male sterility (P/TGMS) is widely applied for improving crop production. Previous investigations using the reversible male sterile (rvms) mutant showed that slow development is a general mechanism for restoring fertility to P/TGMS lines in Arabidopsis. In this work, we isolated a restorer of rvms-2 (res3), as the male sterility of rvms-2 was rescued by res3. Phenotype analysis and molecular cloning show that a point mutation in UPEX1 l in res3 leads to delayed secretion of callase A6 from the tapetum to the locule and tetrad callose wall degradation. Electrophoretic mobility shift assay and chromatin immunoprecipitation analysis demonstrated that the tapetal transcription factor ABORTED MICROSPORES directly regulates UPEX1 expression, revealing a pathway for tapetum secretory function. Early degradation of the callose wall in the transgenic line eliminated the fertility restoration effect of res3. The fertility of multiple known P/TGMS lines with pollen wall defects was also restored by res3. We propose that the remnant callose wall may broadly compensate for the pollen wall defects of P/TGMS lines by providing protection for pollen formation. A cellular mechanism is proposed to explain how slow development restores the fertility of P/TGMS lines in Arabidopsis.

Abstract
Heavy metal cadmium (Cd), a classical environmental pollutant, causes placental apoptosis and fetal growth restriction (FGR), whereby the mechanism remains unclear. Here, our human case-control study firstly showed that there was a positive association of Parkin mitochondrial translocation, MCL-1 reduction, placental apoptosis, and all-cause FGR. Subsequently, Cd was administered to establish in vitro and in vivo models of placental apoptosis or FGR. Our models demonstrated that Parkin mitochondrial translocation was observed in Cd-administrated placental trophoblasts. Meaningfully, Parkin siRNA (siR) dramatically mitigated Cd-triggered apoptosis in placental trophoblasts. Mdivi-1 (M-1), an inhibitor for Parkin mitochondrial translocation, mitigated Cd-induced apoptosis in placental trophoblasts, which further ameliorated the effect of attenuated placental sizes in Cd-exposed mice. Furthermore, the interaction of MCL-1 with Parkin or Ub in Cd-stimulated cells was stronger than that in controls. MG132, an inhibitor for proteasome, abolished MCL-1 degradation in Cd-stimulated cells. Importantly, Parkin siR and M-1 memorably abolished the ubiquitin-dependent degradation of MCL-1 in placental trophoblasts. Interestingly, mito-TEMPO and melatonin, two mitochondria-targeted antioxidants, obviously rescued Cd-caused mitochondrial membrane potential (MMP) decrease, Parkin mitochondrial translocation, MCL-1 degradation, and apoptosis in placental trophoblasts. In conclusion, cadmium induces placental apoptosis and FGR via mtROS-mediated Parkin-modulated degradation of MCL-1.

Abstract
Objective Limited attention has been paid to abnormal blood and urine test results for patients with bladder cancer. The present study aimed to identify whether blood and urine parameters are associated with bladder cancer. Methods We used a case–control design and matched each patient with bladder cancer with three healthy controls of the same age and sex. Univariate conditional logistic regression was used to calculate the crude and adjusted odds ratio (OR) and its 95% CI. Multivariate conditional logistic regression was performed for confounders adjustment, and Spearman’s correlation coefficient was used to assess the correlation between tumor T stages and urine parameters. Results Patients with bladder cancer (n = 360) and controls (n = 1050) were recruited. In the univariate conditional logistic analysis, higher urine pH was associated with a decreased risk of bladder cancer (OR = 0.67, 95% CI = 0.57–0.78), while higher values of urine protein (OR = 4.55, 95% CI = 3.36–6.15), urine glucose (OR = 1.56, 95% CI = 1.18–2.05), and urine occult blood (OR = 4.27, 95% CI = 3.44–5.29) were associated with an increased risk of bladder cancer. After adjustment for body mass index, fasting blood glucose, hypertension, red blood cells, white blood cells, lymphocytes, neutrophils, and platelets, significance still remained for urine pH (OR = 0.68, 95% CI = 0.53–0.88), urine protein (OR = 1.97, 95% CI = 1.21–3.19), urine glucose (OR = 2.61, 95% CI = 1.39–4.89), and urine occult blood (OR = 3.54, 95% CI = 2.73–4.58). Conclusion This study indicated that lower urine pH and higher values of urine protein, urine glucose, and urine occult blood might be risk factors for bladder cancer.

Abstract
Environmental cadmium (Cd) is positively associated with placental impairment and fetal growth retardation. Nevertheless, its potential mechanisms remain unclear. microRNAs (miRNAs) are known to influence placental development and fetal growth. This work was aimed to determine which miRNAs are involved in Cd-impaired placental and fetal development based on the mRNA and miRNA expression profiles analysis. As a result, gestational Cd exposure deceased fetal and placental weight, and reduced the protein level of PCNA in human and mouse placentae. Furthermore, the results of mRNA microarray showed that Cd-downregulated mRNAs were predictively correlated with several biological processes, including cell proliferation, differentiation and motility. In addition, the results of miRNA microarray and qPCR assay demonstrated that Cd significantly increased the level of miR-6769b-5p, miR-146b-5p and miR-452-5p. Integrated analysis of Cd-upregulated miRNAs predicted target genes and Cd-downregulated mRNAs found that overlapping mRNAs, such as CCND1, CDK13, RINT1 and CDC26 were also significantly associated with cell proliferation. Further experiments showed that miR-6769b-5p inhibitor, but not miR-146b-5p and miR-452-5p, markedly reversed Cd-downregulated the expression of proliferation-related mRNAs, and thereby restored Cd-decreased the proteins level of CCND1 and PCNA in human placental trophoblasts. Dual luciferase reporter assay further revealed that miR-6769b-5p directly targets CCND1. Finally, the case-control study demonstrated that increased miR-6769b-5p level and impaired cell proliferation were observed in small-for-gestational-age human placentae. In conclusion, miR-6769b-5p targets CCND-1 to regulate proliferation in Cd-treated placental trophoblasts, which is associated with the impairment of fetal growth. Our findings imply that placental miR-6769b-5p may be used as an epigenetic marker for environmental pollutants-caused fetal growth restriction and its late-onset chronic diseases.

Abstract
The objective of this study was to compare the efficacy and safety of 10 different surgical treatments for benign prostatic hyperplasia (BPH) with volume >60 mL. A systematic literature review and network meta-analysis of randomized controlled trials (RCTs) within a Bayesian framework was performed. A total of 52 parallel-group RCTs included, reporting on 6,947 participants, comparing open prostatectomy (OP), monopolar/bipolar transurethral resection of prostate (monopolar/ bipolar TURP), thulium, holmium and diode laser enucleation of prostate (LEP), bipolar enucleation of prostate, potassium titanyl phosphate laser vaporization of prostate (KTP LVP), bipolar vaporization of prostate (bipolar VP), and laparoscopic simple prostatectomy (laparoscope SP). Compared with OP, laparoscope SP identified better maximal flow rate (Qmax; mean differences [MDs] = 2.89 mL/s) at the 24th month, but bipolar VP demonstrated worse Qmax (MD = −3.20 mL/s) and International Prostate Symptom Score (IPSS; MD = 2.60) at the 12th month. Holmium LEP (MD = 1.37) demonstrated better International Index of Erectile Function–5 at the 12th month compared with OP. However, compared with OP, KTP LVP demonstrated worse postvoid residual volume (PVR) at the sixth (MD = 10.42 mL) and 12th month (MD = 5.89 mL) and monopolar TURP (MD = 6.9 mL) demonstrated worse PVR at the 12th month. Eight new surgical methods for BPH with volume >60 mL appeared to be superior in safety compared with OP and monopolar TURP due to fewer complications. Bipolar VP and KTP LVP maybe not suitable for prostates more than 60 mL due to short- and middle-term worse Qmax, IPSS, and PVR than OP.

Abstract
PURPOSE The quality of recovery (QoR) is an important indicator of a patient's health status in the early postoperative period. Despite its importance, the QoR from the patient's perspective is often neglected in clinical practice. This study was performed to survey and determine the QoR of surgical patients from their own subjective perspective and to provide a reference for the targeted postoperative care of surgical patients in the future. DESIGN A descriptive and cross-sectional study. METHODS The Chinese version of the Quality of Recovery-15 (QoR-15) scale was used to survey the QoR of 503 surgical patients in 20 surgical wards from 17 surgical departments of a large tertiary hospital in Sichuan Province, China. A questionnaire survey was administered to each patient before and after the operation, and the scores were compared. FINDINGS There were no significant differences in "feeling worried or anxious" and "feeling sad or depressed" between the preoperative and postoperative periods (P > 0.05). The postoperative scores for the other items were significantly lower than the preoperative scores. The total postoperative QoR-15 score was significantly lower than the total preoperative score (P < 0.001). CONCLUSIONS The QoR-15 scores of surgical patients were lower after the surgery than before, and patients still needed care after discharge. Therefore, due to the gradual shortening of the length of stay (LOS) of surgical patients, it is necessary for hospitals to construct a complete surgical patient transitional care process to meet the needs of patients after discharge and promote patient rehabilitation.

Abstract
Most randomized trials for acute promyelocytic leukemia (APL) have investigated highly selected patients under idealized conditions, and the findings need to be validated in the real world. We conducted a population-based study of all APL patients in Zhejiang Province, China, with a total population of 82 million people, to assess the generalization of all-trans retinoic acid (ATRA) and arsenic as front-line treatment. The outcomes of APL patients were also analyzed. Between January 2015 and December 2019, 1,233 eligible patients were included in the final analysis. The rate of ATRA and arsenic as front-line treatment increased steadily from 66.2% in 2015 to 83.3% in 2019, with no difference among the size of the center (≥5 or <5 patients per year, p = 0.12) or age (≥60 or <60 years, p = 0.35). The early death (ED) rate, defined as death within 30 days after diagnosis, was 8.2%, and the 3-year overall survival (OS) was 87.9% in the whole patient population. Age (≥60 years) and white blood cell count (>10 × 109/L) were independent risk factors for ED and OS in the multivariate analysis. This population-based study showed that ATRA and arsenic as front-line treatment are widely used under real-world conditions and yield a low ED rate and a high survival rate, which mimic the results from clinical trials, thereby supporting the wider application of APL guidelines in the future.

Abstract
BACKGROUND The burden of kidney, bladder, and prostate cancers has changed in recent decades. This study aims to investigate the global and regional burden of, and attributable risk factors for genitourinary cancers during the past 30 years. METHODS We extracted data of kidney, bladder, and prostate cancers from the Global Burden of Disease 2019 database, including incidence, mortality, disability-adjusted life-years (DALYs), and attributable risk factors from 1990 to 2019. Estimated annual percentage changes (EAPC) were calculated to assess the changes in age-standardized incidence rate, age-standardized mortality rate (ASMR), and age-standardized DALYs rate (ASDR). The associations between cancers burden and socio-demographic index (SDI) were also analyzed. RESULTS Compared with 1990, the global incident cases in 2019 were higher by 154.78%, 123.34%, and 169.11% for kidney, bladder, and prostate cancers, respectively. During the 30-year study period, there was a downward trend in ASMR and ASDR for bladder cancer (EAPC = - 0.68 and - 0.83, respectively) and prostate cancer (EAPC = - 0.75 and - 0.71, respectively), but an upward trend for kidney cancer (EAPC = 0.35 and 0.12, respectively). Regions and countries with higher SDI had higher incidence, mortality, and DALYs for all three types of cancers. The burden of bladder and prostate cancers was mainly distributed among older men, whereas the burden of kidney cancer increased among middle-aged men. Smoking related mortality and DALYs decreased, but high body mass index (BMI) and high fasting plasma glucose (FPG) related mortality and DALYs increased among kidney, bladder, and prostate cancers during the study period. CONCLUSIONS Kidney, bladder, and prostate cancers remain major global public health challenges, but with distinct trend for different disease entity across different regions and socioeconomic status. More proactive intervention strategies, at both the administrative and academic levels, based on the dynamic changes, are needed.

Abstract
Severe Coronavirus Disease 2019 (COVID-19) is characterized by numerous complications, complex disease, and high mortality, making its treatment a top priority in the treatment of COVID-19. Integrated traditional Chinese medicine (TCM) and western medicine played an important role in the prevention, treatment, and rehabilitation of COVID-19 during the epidemic. However, currently there are no evidence-based guidelines for the integrated treatment of severe COVID-19 with TCM and western medicine. Therefore, it is important to develop an evidence-based guideline on the treatment of severe COVID-19 with integrated TCM and western medicine, in order to provide clinical guidance and decision basis for healthcare professionals, public health personnel, and scientific researchers involved in the diagnosis, treatment, and care of COVID-19 patients. We developed and completed the guideline by referring to the standardization process of the "WHO handbook for guideline development", the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, and the Reporting Items for Practice Guidelines in Healthcare (RIGHT).

Abstract
Aim: The purpose of our study was to assess the differences between HIV-negative cryptococcal meningitis (CM) patients with and without autoimmune diseases. Methods: A total of 43 CM patients with autoimmune diseases and 67 without autoimmune diseases were enrolled for analysis. Results: CM patients with autoimmune diseases had higher fever, modified Rankin Scale scores, C-reactive protein and erythrocyte sedimentation rate, but had lower rates of visual and hearing symptoms, ventriculoperitoneal shunts, MRI meningeal enhancement and amphotericin B treatment, as well as lower cerebrospinal fluid pressure and fungal counts. When divided according to gender, each group had lower intracranial pressure and higher inflammation indicators. No differences in outcomes, sequelae and mortality hazard were found. Fluconazole treatment was a prognostic factor for CM without autoimmune diseases. Conclusions: Both antifungal and anti-inflammatory therapy should be considered in CM patients with autoimmune diseases.

Abstract
OBJECTIVE To compare the efficiency of the target gene panel method and whole-exome sequencing (WES) in detecting idiopathic hypogonadotropic hypogonadism (IHH), and select a more suitable gene detection method. METHODS We selected 24 genes closely related to the molecular pathogenesis of IHH to make up the gene panel, detected the mutation sites in 73 patients with IHH using the panel method, and verified the results of sequencing with the Sanger method. Using the key words "idiopathic hypogonadotropic hypogonadism", we searched databases for relevant literature, calculated the positive rate of IHH detected by WES and compared it with that detected with the panel method. RESULTS Of the 73 cases of IHH detected with the panel method, 7 were found with pathogenic mutations, including 2 cases of FGFR1, 2 cases of CHD7, 2 cases of KISS1R, and 1 case of NR5A1 mutation. Sanger sequencing showed that the positive rate of the panel method was 9.7%. Of the 1 336 articles retrieved, 5 met the inclusion criteria and were included, in which WES revealed a positive rate of about 30%. CONCLUSIONS For detection of the diseases with clear mutated genes, the panel method is relatively inexpensive and has a high sequencing depth, while for detection of the diseases with complicated genetic patterns and unclear mutated genes, WES is more efficient. Further studies are needed for choice of the two methods for different purpose of detection./.

Abstract
Gestational exposure to environmental Cd caused placental angiogenesis impairment and fetal growth restriction (FGR). However, its mechanism remained unclear. This study was to investigate the effects of Cd exposure during pregnancy on placental angiogenesis and its mechanism. Pregnant mice were exposed to CdCl2 (4.5 mg/kg) on gestational day (GD) 8 with or without melatonin (MT) (5.0 mg/kg), an anti-endoplasmic reticulum stress agent, from GD7 to GD15. Human primary placental trophoblasts and JEG-3 cells were stimulated using CdCl2 (20 μM) after MT (1 mM) preprocessing. We firstly found MT treatment obviously mitigated environmental Cd-induced placental angiogenesis disorder and reduction of the VEGF-A level. Mechanistically, MT reversed environmental Cd-downregulated the protein expression of VEGF-A via inhibiting glucocorticoid receptor (GR) activation. Notably, our data showed MT treatment antagonized Cd-activated GC/GR signaling via blocking PERK signaling and thereby upregulated VEGF-A and 11β-HSD2 protein expression. Based upon the population case-control study, the levels of VEGF-A and 11β-HSD2 protein in small-for-gestational-age placentae were significantly reduced when compared to appropriate-for-gestational-age placentae. Overall, environmental Cd exposure during gestation impaired placental angiogenesis via PERK-regulated GC/GR signaling in placental trophoblasts. Our findings will provide a basis for prevention and treatment of placental impairments and fetal growth restriction caused by environment toxicants in future.

Abstract
OBJECTIVE To analyze the effects of high-fat diet on the biological network regulation of gene expression microarray data and key proteins in mouse prostate tissue, and provide some new theoretical evidence for the mechanism of obesity inducing PCa. METHODS From the Gene Expression Omnibus (GEO), we obtained RNAs in the prostate tissue from two groups of C57BL / 6J mice, the normal diet group (n = 5) and high-fat diet group (n = 4). Using the Gene Cloud, Gene-Cloud of Biotechnology Informs (GCBI), GenClip2.0, and Sytoscape 3.5.1, we screened differentially expressed genes, investigated protein interaction networks and biological pathways of differential genes and, from the perspective of transcriptome, explored the effects of high-fat diet on the changes of the molecular network of prostate tissue genes and the molecular biological functions possibly involved. RESULTS A total of 134 differentially expressed genes were identified, 130 up-regulated and 4 down-regulated, mainly involved in biological functions such as chromosome organization, cell-cell signaling, small molecule biosynthesis and leukocyte activation. The Lck, Prkcb and Cd28 genes in the gene network were of high value, indicating an important relationship with protein synthesis and biological functions, the core node of the protein-protein network, and a high predictive ability of Lck and Cd28. CONCLUSIONS The high-fat diet can induce changes in prostate tissue genes, leading to tumorigenesis.

Abstract
The objective of this study is to provide comprehensive and up-to-date estimates on the disease burden of BPH in 204 countries and territories between 1990 and 2019. Data about incidence, year lived with disability (YLD), and their age-standardized rates (ASRs) for 21 regions, 5 Socio-demographic Index (SDI) quintiles, 204 countries and territories, and 12 age categories from 1990 to 2019 were obtained from the Global Burden of Disease 2019 study. Estimated annual percentage changes (EAPCs) of the ASRs and the associations between SDI and the ASRs were estimated. The effects of population growth, population aging, and age-specific rate on the changes in the absolute numbers of incidence and YLD were quantified. Globally, there were 11.26 million (95% uncertainty interval [UI]: 8.79, 14.46) new cases and 1.86 million (95%UI: 1.13, 2.78) YLD due to BPH in 2019. The global ASRs of incidence (EAPC: −0.031, 95% CI: −0.050, −0.012) and YLD (EAPC: −0.058, 95% CI: −0.084, −0.031) decreased slightly from 1990 to 2019, whereas the absolute numbers increased dramatically from 1990 (incidence by 105.7% and YLD by 110.6%), mainly driven by the population growth (53.5% for incidence and 54.4% for YLD) and population aging (55.7% for incidence and 63.2% for YLD). The burden of BPH varied markedly among different regions, socioeconomic status, and countries. As the population is growing and aging, great efforts are required to develop effective prevention, treatment and management strategies to meet the high and increasing burden of BPH worldwide.

Abstract
We consider the bending effect on the formation of Majorana bound states (MBSs) in planar Josephson junctions where the normal stripe is tilted in a V shape. Our results show that the MBSs remain robust for moderate bending angles. Beyond some critical angles, the degradation of MBSs can be revealed by its eigenspectrum as well as the Majorana polarization (MP). Our results show that the parameter space of bending angle for robust MBSs can be significantly enlarged by tuning the superconducting phase difference across the Josephson junction. These findings suggest that the interplay of the junction geometry and the device parameters provides richer degree of freedom in designing topological superconducting devices for future applications. The MP analysis is an indispensable tool for characterizing the Majorana states.

Abstract
Serine proteinase inhibitor B9 (serpin B9) is a member of the serine protease inhibitor superfamily, which is widely found in animals, plants and microorganisms. Serpin B9 has been reported to protect cells from the immune‑killing effect of granzyme B (GrB) released by lymphocytes. In recent years, an increasing number of studies have indicated that serpin B9 is involved in tumour apoptosis, immune evasion, tumorigenesis, progression, metastasis, drug resistance and even in maintaining the stemness of cancer stem cells (CSCs). Moreover, according to clinical studies, serpin B9 has been demonstrated to be significantly associated with the development of precancerous lesions, a poor prognosis and ineffective therapies, suggesting that serpin B9 may be a potential target for cancer treatment and an indicator of cancer diagnosis; thus, it has begun to attract increased attention from scholars. The present review concisely described the structure and biological functions of the serpin superfamily and serpin B9. In addition, related research on serpins in cancer is discussed in order to provide a comprehensive understanding of the role of serpin B9 in cancer, as well as its clinical significance for cancer diagnosis and prognosis.

Abstract
Objective: To evaluate the performance of the European Evidence-based Guidelines on Pancreatic Cystic Neoplasms (EEGPCN)(2018) and International Association of Pancreatology(IAP) Guideline(Version 2017) in predicting high grade dysplasia/invasive carcinoma-intraductal papillary mucinous neoplasm(HGD/INV-IPMN). Methods: A retrospective analysis of 363 patients,who underwent surgical resection in Changhai Hospital affiliated to Navy Medical University from January 2012 to December 2018 and were pathologically identified as (intraductal papillary mucinous neoplasm, IPMN),was performed. The patients,including 230 males and 133 females,aging (61.7±10.1) years(range:19 to 83 years). The proportion of HGD/INV-IPMN who met with the absolute indication(AI) of EEGPCN and high risk stigma(HRS) of IAP were compared. The binary Logistic regression analysis was used to find the independent risk factors of HGD/INV-IPMN.Eight combinations of risk factors derived from relative indication/worrisome feature or risk factors in this study,were made to evaluate the diagnostic efficacy. The area under curve(AUC) of receiver operating characteristics was used to evaluate the the cutoff value of risk factors(①CA19-9≥37 U/ml,②diameter of main pancreatic duct 5.0-9.9 mm,③enhancing mural nodule<5 mm,④(acute) pancreatiti,⑤acyst diameter ≥40 mm,⑤bcyst diameter ≥30 mm, ⑥thickened or enhancing cyst walls,⑦neutrophile granulocyte to lymphocyte ratio(NLR)≥2, ⑧cyst located in head, uncinate or neck,⑨carcinoembryonic antigen(CEA) ≥5 μg/L) number for predicting HGD/INV-IPMN.The accuracy,sensitivity,specificity,positive predictive value,negative predictive value,true positive,true negative,false positive,false negative,positive likelihood ratio,negative likelihood ratio,Youden index and F1 score were calculated. Results: Ninety-two patients(49.5%) of 186 ones who met AI and 85 patients(48.3%) of 176 ones who met HRS were respectively confirmed as HGD/INV-IPMN. In those patients who were not met AI,tumor location,thickened/enhancing cyst wall,CA19-9 elevated,NLR≥2 and CEA elevated were significantly (P<0.05) correlated with HGD/INV-IPMN. And tumor location(head/uncinate/neck vs. body/tail,OR=3.284,95%CI:1.268-8.503,P=0.014),thickened/enhancement cyst wall (with vs.without,OR=2.713,95%CI:1.177-6.252,P=0.019),CA19-9(≥37 U/L vs.<37 U/L, OR=5.086,95%CI:2.05-12.62,P<0.01) and NLR(≥2 vs.<2,OR=2.380,95%CI:1.043-5.434,P=0.039) were the independent risk factors of HGD/INV-IPMN. Patients with ≥4 risk factors of 9 in combination Ⅷ(①②③④⑤b⑥⑦⑧⑨) were diagnosed as HGD/INV-IPMN with the moderate accuracy(71.0%),moderate sensitivity (62.0%) and moderate specificity (73.0%). Patients with ≥4 risk factors of 9 in Combination Ⅶ(①②③④⑤a⑥⑦⑧⑨) were diagnosed as HGD/INV-IPMN with the highest specificity(83.0%) and patients with ≥3 risk factors of 8 in combination Ⅵ(①②③④⑤b⑥⑧⑨) were diagnosed as HGD/INV-IPMN with the highest sensitivity(74.0%). The AUC for diagnosis of HGD/INV-IPMN in combination Ⅵ,Ⅶ and Ⅷ were 0.72,0.75 and 0.75,respectively. Older patients and younger patients could respectively refer to combination Ⅶ and combination Ⅵ to improve the management of IPMN. Conclusions: Patients who meet AI of EEGPCN should undertake resection, otherwise the method we explored is recommended. The method of improvement for diagnosis of HGD/INV-IPMN is relatively applicable and efficient for decision-making of surgery, especially for younger patients with decreasing of missed diagnosis and elder patients with decreasing of misdiagnosis.

Abstract
Hypoxia is a common phenomenon during tumorigenesis and tumour development. In recent years, studies have found that hypoxia‑inducible factor (HIF)‑2α, also referred to as endothelial PAS domain protein‑1, plays an important role in tumours. HIF‑2α is an important oncogene and a critical prognostic indicator in non‑small cell lung cancer. However, no unified conclusion can be drawn concerning HIF‑2α and small cell lung cancer, since few studies to date have focused on their association. An increasing number of studies have confirmed that HIF‑2α is involved in tumorigenesis, cell proliferation, angiogenesis, metastasis, drug resistance and radiotherapy failure in lung cancer. Of note, HIF‑2α plays a crucial role in lung cancer to maintain cancer cell stemness. Based on the importance of HIF‑2α in lung cancer, HIF‑2α‑targeted therapy has been attracting increasing attention. Although this strategy currently appears to be promising in vitro, it has never been assessed as a therapy for lung cancer. The aim of the present review was to summarize the contribution of HIF‑2α to various aspects of lung cancer, as well as its potential as targeted therapy.

Abstract
Cadmium (Cd), an environmental toxicant, is positively associated with fetal growth restriction (FGR). However, the mechanism by which gestational exposure to Cd induces FGR remains unclear. This study designed in vitro and in vivo experiments to explore the role of placental mitophagy in Cd-impaired fetal growth. Based on our case-control study, we also investigated the association of placental mitophagy with reduced progesterone (P4) level and all-cause FGR. We firstly found environmental Cd exposure lowered the P4 content in maternal sera, placentae and amnioticfluids of mice. The level of three mitochondrial P4 synthases, including StAR, CYP11A1 and 3β-HSD, was also reduced in Cd-treated placentae. Furthermore, Cd triggered mitophagy, as determined by the degradation of two mitochondrial proteins HSP60 and COX IV, and the accumulation of co-localizations of TOM20 with LC3B or Parkin in placental trophoblasts. Correspondingly, Cd elevated mitochondrial Parkin level in placental trophoblasts. Mdivi-1, a mitophagy inhibitor, obviously attenuated Cd-induced reduction of placental P4 and FGR in mice. Moreover, mdivi-1 and Parkin siRNA (siR) markedly reversed Cd-caused P4 synthesis inhibition in human placental trophoblasts. Interestedly, the PERK/ATF4 signaling was activated in Cd-stimulated placental trophoblasts. PERK siR inhibited mitochondrial proteins degradation in Cd-stimulated placental trophoblasts. In particularly, mitophagy activation and P4 synthesis suppression occurred in small-for-gestational-age placentae based on our case-control study. Environmental Cd exposure induced FGR via activating PERK-regulated mitophagy and inhibiting P4 synthesis in placentaltrophoblasts. Furthermore, placental mitophagy was related to the reduced progesterone level and all-cause fetal growth restriction based on our case-control study. As above, placental mitophagy maybe the common mechanism of environmental toxicants-impaired fetal growth.

Abstract
A 60-year-old male patient presented with a serum α-fetoprotein (AFP) level of 2940.5 ng/mL accompanied by a significant increase in serum globulin. Hepatitis B virus (HBV) DNA was 2.85 × 103 (normal value <1.0 × 103). B-mode ultrasound and magnetic resonance imaging showed characteristic manifestations and he was clinically diagnosed with hepatocellular carcinoma in January 2015. He received radiofrequency ablation and tenofovir disoproxil anti-HBV therapy and his serum AFP and globulin levels were significantly reduced. In March 2018, he presented at our Hematology Department with fatigue and a pale complexion. At that time, his serum AFP level was normal, with hemoglobin 61 g/L and globulin 64.7 g/L. He was diagnosed with multiple myeloma (MM) by bone marrow examination, and immunofixation electrophoresis. The patient received PCD chemotherapy (bortezomib 2.0 g/dL on days 1, 4, 8, and 11 plus cyclophosphamide 0.3 g/dL on days 1-4 plus dexamethasone 20 mg/dL on days 1-2, 4-5, 8-9, and 11-12). The patient finally died of MM complicated by disseminated intravascular coagulation.

Abstract
Magnesium (Mg) is an abundant and important cation in cells. Plants rely on Mg transporters to take up Mg from the soil, and then Mg is transported to anthers and other organs. Here, we showed that MGT6+/- plants display reduced fertility, while mgt6 plants are fertile. MGT6 is expressed in the anther at the early stages. Pollen mitosis and intine formation are impaired in aborted pollen grains (PGs) of MGT6+/- plants, which is similar to the defective pollen observed in mgt5 and mgt9 mutants. These results suggest that Mg deficiency leads to pollen abortion in MGT6+/- plants. Our data showed that mgt6 organs including buds develop significantly slower and mgt6 stamens accumulate a higher level of Mg, compared with wild-type (WT) and MGT6+/- plants. These results indicate that slower bud development allows mgt6 to accumulate sufficient amounts of Mg in the pollen, explaining why mgt6 is fertile. Furthermore, we found that mgt6 can restore fertility of mgt5, which has been reported to be male sterile due to defects in Mg transport from the tapetum to microspores and that an additional Mg supply can restore its fertility. Interestingly, mgt5 fertility is recovered when grown under short photoperiod conditions, which is a well-known factor regulating plant fertility. Taken together, these results demonstrate that slow development is a general mechanism to restore mgts fertility, which allows other redundant magnesium transporter (MGT) members to transport sufficient Mg for pollen formation.

Abstract
Scanning tunneling microscopy (STM) is an indispensable tool in detecting Majorana bound states (MBSs) in vortices of topological superconductors. By reducing the computational complexity via non-uniform grids, we systematically study the tunnel coupling as well as the temperature dependence of the differential conductance of MBSs in two dimensional devices. Numerical results show that the conductance peak approaches the quantized value 2e 2/h in strong coupling limit at low temperatures which are characteristic features of MBSs. More interestingly, a conductance local minimum in the spatially scanning is observed when the STM tip is placed at the vortex center. The dip structure can be enhanced with increased temperature or enlarged vortex size. We ascribe this observation to the sensitivity of the Andreev reflection processes of carriers at the vortex center where the thermal energy could be comparable to the vanishing pair potential. We also investigate the STM of two-vortex systems where the hybridization of the vortices can lead to oscillatory behavior of the state energy. With small inter-vortex distances, the original MBSs in vortices can merge into topologically trivial states and the conductance peak can be significantly suppressed.

Abstract
Cadmium (Cd), a well-known environmental pollutant, can lead to placental insufficiency and fetal growth restriction. However, the underlying mechanism is unknown. The purpose of our study is to explore the effect of Cd on placental angiogenesis and its mechanism using in vitro and in vivo models. Results found that gestational Cd exposure obviously decreased placental weight and impaired placental vascular development in mice. Correspondingly, Cd exposure evidently downregulated the expression of VEGF-A protein (a key indicator of angiogenesis) and progesterone receptor (PR) in placental trophoblasts. Further experiment showed that lentivirus PR overexpression reversed Cd-caused the reduction of VEGF-A level in human placental trophoblasts. In addition, Cd significantly reduced progesterone level, down-regulated the expression of key progesterone synthase (StAR, CYP11A1), and activated mitochondrial stress response and GCN-2/p-eIF2α signaling in placental trophoblasts. Additional experiment showed that GCN-2 siRNA pretreatment markedly alleviated Cd-activated mitochondrial stress response, restored Cd-downregulated the expression of CYP11A1, reversed Cd-reduced the level of progesterone and VEGF-A in human placental trophoblasts. Finally, our case-control study confirmed that impaired placental angiogenesis and reduced progesterone level occurred in all-cause small for gestational age placenta. Taken together, environmental exposure to Cd impairs fetal growth and placental angiogenesis via GCN-2-mediated mitochondrial stress.

Abstract
Fibroblast-like synoviocytes (FLSs) exert a critical effect in the occurrence and progress of rheumatoid arthritis (RA). MicroRNA-495 (miR-495) can regulate many growth behaviors in various cell types. Nevertheless, the role of miR-495 is still unclear in RA-FLS. We aimed to explore the role and molecular mechanism of miR-495 in RA. The FLSs and synovial tissue from normal and RA cases were used in the study. RT-PCR analysis was used to examine the expression of miR-495. Western blot assay was conducted to determine the levels of matrix metalloproteinase-9 (MMP-9), matrix metalloproteinase-2 (MMP-2) and β-catenin. Cell counting kit-8 (CCK-8) assays were performed to determine the proliferation of RA-FLS in different treatment groups. The results showed that miR-495 is down-regulated in both RA-synovial tissue and RA-FLSs. Overexpression of miR-495 could inhibit RA-FLS proliferation and inflammatory factors of interleukin (IL)-6, IL-11 and tumor necrosis factor alpha (TNF-α), and decrease the protein expression of MMP-9 and MMP-2. In addition, miR-495 could negatively regulate the expression of β-catenin in RA-FLSs. We also confirmed that the inhibitory role of miR-495 in RA-FLS is through the regulation of β-catenin expression. Taken together, miR-495 is downregulated in RA-FLS and RA synovial tissue, and miR-495 inhibits proliferation and inflammatory response in RA-FLS, partially via regulating β-catenin expression. The miR-495/β-catenin pathway may serve as a new therapeutic target for RA.

Abstract
Objective: To summarize the clinical characteristics and laboratory diagnostic methods of infant botulism caused by Clostridium botulinum type B. Methods: Clinical data of 3 infants with type B botulism who were admitted to Children's Hospital Affiliated to Capital Institute of Pediatrics from May to November 2018 were retrospectively analyzed. Botulinum toxin was detected in fecal samples or fecal enrichment solution of the patients, and Clostridium botulinum was cultured and isolated from fecal samples. Results: The age of onset of the patients (two boys and one girl) was 3, 3 and 8 months old, respectively. Two cases had the onset in May and one case had the onset in November. There were two cases with mixed feeding and one case with breast feeding. One case's family members engaged in meat processing. All of them were previously healthy. All the children presented with acute flaccid paralysis, cranial nerve involvement and difficult defecation. Two cases had secondary urinary tract infection. Electromyograms of two cases showed that action potential amplitude of the motor nerve were lower than those of their peers. After treatments including intravenous human immunoglobulin, respiratory tract management, urethral catheterization, nasal feeding, etc., three cases recovered completely 2 to 4 months later. Type B botulinum toxin was detected in the fecal diluent of one patient, and the TPGYT enrichment solution and cooked meet medium of the feces of 3 patients, respectively. Clostridium botulinum B was identified from the feces of 3 infants after culture, isolation and purification. Conclusions: Combined with typical clinical manifestations including acute flaccid paralysis, cranial nerve involvement symptoms and difficult defecation examination, infant botulism can be clinically diagnosed. The detection of fecal botulinum toxin and the culture and isolation of Clostridium botulinum are helpful for the diagnosis.

Abstract
OBJECTIVE To investigate the relationship between microRNA-34b/c single nucleotide polymorphism (SNP) rs4938723 and the risk of male infertility. METHODS This case-control study included 553 males aged 19-40 (29.42 ± 5.09) years with idiopathic infertility, 153 with azoospermia and 400 with oligoasthenospermia, and another 332 normal fertile men aged 19-40 (28.5 4 ± 4.63) years as controls. We collected the clinical data and peripheral blood samples from the subjects, genotyped microRNA-34b/c rs4938723 by Sequenom MassARRAY, and analyzed the relationship between the genotypes of microRNA-34b/c rs4938723 and the risk of male infertility using the logistic regression model. RESULTS Statistically significant differences were observed between the infertility patients and normal controls in sperm concentration ([18.71 ± 15.19] vs [79.91 ± 43.96] × 10⁶/ml, P < 0.01), the percentage of progressively motile sperm ([13.27 ± 24.52]% vs [42.82 ± 8.86]%, P < 0.01) and the level of follicle stimulating hormone ([16.09 ± 17.37] vs [12.20 ± 4.73] IU/L, P < 0.01). Compared with the TT genotype, the TC and CC genotypes showed no correlation with male infertility, nor did the genetic locus in the subgroup analysis. CONCLUSIONS No correlation was found between microRNA-34b/c SNP rs4938723 and male infertility, which, however, needs to be further verified by larger-sized samples.

Abstract
Background: The frequent emergence of the re-positive patients with COVID-19 is a potential threat worldwide. This study aimed to describe data from admission to follow-up for patients with COVID-19 and analyze the possible causes for re-positive nucleic acid tests to provide more scientific basis for reducing the numbers of re-positive patients after discharge. Methods: We retrospectively recorded 15 patients with COVID-19 admitted to the Xianyang Central Hospital, China. The baseline, exposure histories, clinical syndromes, laboratory characteristics, nucleic acid, and follow-up tests were analyzed, and the radiological characteristics of re-positive patient at different periods were compared. Results: Eight (53.33%) patients had the history of travel to Wuhan, four (26.67%) patients had close contact with confirmed patients, and one (6.67%) patient had close contact with suspected patients. After treatment, all patients had two consecutively negative nucleic acid tests and were discharged from hospital. All patients were followed up for more than 14 days, and the average time from discharge to the first follow-up was 14.67 ± 3.31 days (from 9 to 22 days). Most patients showed no clinical symptoms and negative nucleic acid tests, while one patient had an itchy throat, her CT scan showed a light density shadow in the right lower lobe of the lung, and the nucleic acid was once again positive. The second follow-up of the other 14 patients (except the re-positive one) was conducted 20.80 ± 7.78 days (from 13 to 30 days) after discharge, and all of them had negative nucleic acid tests. The positive patient was immediately readmitted and received a new round of treatment. Her family members and colleagues remained healthy until now. Conclusions: The quality of nucleic acid testing reagents should be enhanced, and the training of nucleic acid sampling operators should be strengthened to reduce the false-negative results in the nucleic acid of SARS-CoV-2; the clinical specimens of throat and nasopharynx swabs can be collected at the same time; IgM- and IgG-specific antibodies of SARS-CoV-2 should be carried out for discharged patients; the radiological characteristics should be evaluated strictly; and the discharge standard can be specified according to the baseline and severity of disease of patients.

Abstract
Objective: To investigate the effect and mechanism of miR-451 on the proliferation and migration of human colorectal cancer cell SW480 by targeting macrophage migration inhibitory factor (MIF). Methods: Microarray analysis was used to screen differentially expressed microRNAs and messenger RNA in SW480 cells. Real-time quantitative PCR (RT-qPCR) was used to detect the expressions of miR-451 and MIF in SW480 cells before and after transfection. Cell clone formation assay and Transwell assay were used to detect the proliferation and invasion of SW480 cells, respectively. Cell scratch assay was used to detect the migration ability of SW480 cells. The TargetScan database was used to analyze the correlation between miR-451 and MIF. Dual luciferase reporter gene was used to detect the interaction of miR-451 and MIF. MTT assay was used to detect the viability of SW480 cells. Results: Compared with human normal colorectal mucosal cell FHC (1.00), the expression of miR-451 was down-regulated in SW480 cells ( 0.36±0.18, P<0.001). Knockdown of miR-451 promoted proliferation, and migration of SW480 cells. Compared with that in FHC cells, MIF expression was up-regulated in SW480 cells (2.28±0.45, P<0.001). MIF down-regulation inhibited SW480 cell proliferation, invasion and migration. MiR-451 specifically bind to the MIF 3'UTR and regulated the expression of MIF. Overexpression of miR-451 reduced while overexpression of MIF increased the viability of SW480 cells. Overexpression of MIF promoted the proliferation and migration of SW480 cells (P<0.01), reversed the effect of miR-451 suppressed proliferation and migration of SW480 cells. Conclusion: MiR-451 may regulate proliferation and migration of human colorectal cancer cells by targeting MIF.

Abstract
Successful completion of the molting process requires new epidermal growth and ecdysis of the old cuticle in Haemaphysalis longicornis (H. longicornis). MicroRNAs (miRNAs) participate in the development of organisms by inhibiting the expression of their target mRNAs. In this study, a novel tick-specific miRNA was identified and denoted hlo-miR-2 that serves as a novel regulator of molting events in H. longicornis nymphs by targeting a cuticular protein. The full length of this cuticular protein was first obtained and named it CPR1. A qRT-PCR analysis showed that hlo-miR-2 and CPR1 exhibit significant tissue and temporal specificity and that their transcription levels are negatively correlated during the molting process. CPR1, as a direct target of hlo-miR-2, was identified by a luciferase reporter assay in vitro. Agomir treatment indicated that the overexpression of hlo-miR-2 significantly reduced the protein expression level of CPR1, decreased the molting rate and delayed the molting time point in H. longicornis nymphs. RNA interference (RNAi) experiments demonstrated that CPR1 was significantly associated with the molting process in H. longicornis nymphs. Phenotypic rescue experiments convincingly showed that hlo-miR-2 participated in molting events by targeting CPR1 in H. longicornis nymphs. In summary, we present evidence demonstrating that miRNAs constitute a novel important regulator of molting events in addition to hormones. The described functional evidence implicating CPR1 in molting events contributes to an improved understanding of the distinct functions of the CPR family in ticks and will aid the development of a promising application of cuticular protein RNAi in tick control.
