[Feasibility and safety of remote programming in postoperative follow-up of cardiovascular implantable electronic devices].

Objective: To explore the feasibility and safety of remote programming technology based on 5G cloud technology support platform in postoperative follow-up of cardiovascular implantable electronic devices(CIED). Methods: This study was a multicenter cross-sectional study. CIED patients from 12 hospitals lacking full-time follow-up specialists in Sichuan Province were enrolled from June 2021 to October 2021. All patients' devices received remote inspecting and programming by the follow-up specialist of the remote follow-up center of the Third People's Hospital of Chengdu through 5G cloud technology support platform. The baseline data, device alarm events, device reprogramming events, adverse reactions and satisfaction questionnaire survey results were collected. Results: A total of 195 CIED implantation patients were included, with an age of (72.5±11.3) years, including 103 males (52.6%). All patients completed remote inspecting and programming successfully, with a duration of (5.8±4.0) min. Ninety-one patients' CIED were reprogrammed, with a total of 104 parameter adjustments. No abnormal communication or adverse events occurred. The satisfaction questionnaire showed that 97.9%(191/195) of the patients trusted or relatively trusted remote follow-up and 86.7%(169/195) of the patients were willing to choose remote follow-up mode for device management. Conclusion: The remote programming based on 5G cloud technology support platform may be feasible and safe for postoperative follow-up of CIED patients.

Cost-effectiveness analysis of five drugs for treating postmenopausal women in the United States with osteoporosis and a very high fracture risk.

PURPOSE: Five strategies were recommended by the American Association of Clinical Endocrinologists/American College of Endocrinology (AACE/ACE) guidelines for the treatment of postmenopausal osteoporosis (PMO) patients with a very high fracture risk. We aimed to assess their cost-effectiveness in the United States (US). METHODS: A microsimulation Markov model was created to compare the cost-effectiveness of five treatment strategies, including zoledronate, denosumab, abaloparatide, teriparatide, and romosozumab in PMO patients with a recent fracture from the healthcare perspective of the US. The data used in the model were obtained from published studies or online resources. Base-case analysis, one-way deterministic sensitivity analysis (DSA) and probability sensitivity analysis (PSA) were conducted for 65-, 70-, 75-, and 80-year-old patients. RESULTS: In base case, at 65 years, zoledronate was the cheapest strategy. The incremental cost-effectiveness ratios (ICER, which represent incremental costs per QALY gained) of denosumab, teriparatide, abaloparatide, and romosozumab against zoledronate were $13,020/QALY (quality-adjusted years), $477,331 /QALY, $176,287/QALY, and $98,953/QALY, respectively. Under a willing-to-pay (WTP, which means the highest price a consumer will pay for one unit of a good of service) threshold of $150,000/QALY, denosumab and romosozumab were cost-effective against zoledronate. The PSA results showed that denosumab was the most cost-effective option with WTP thresholds of $50,000/QALY, $100,000/QALY and $150,000/QALY. The results were similar in other age groups. The DSA results indicated that the most common parameters that have important influence on the outcome were drug persistence, incidence of adverse events, the efficacy of drugs on hip fractures and the cost of the drug. CONCLUSION AND RELEVANCE: Among PMO patients with a very high fracture risk in the US, zoledronate is the cheapest strategy and denosumab is the most cost-effective choice among these five strategies.

[Effect of Friday surgery on clinical outcome of elderly patients with hip fracture under multidisciplinary treatment].

Objective: To assess the impact of Friday surgery on clinical outcomes in elderly patients with hip fracture under multidisciplinary treatment. Methods: A retrospective cohort study. The clinical data of 414 geriatric patients with hip fractures admitted to Zhongda Hospital Affiliated with Southeast University from January 2018 to March 2021 were analyzed retrospectively, including 126 males and 288 females with a mean age of (81.3±7.6) years. The patients were divided into two groups based on whether they underwent surgery on Friday or not. The Friday group(n=69) and the non-Friday group(n=345) were compared in terms of general information, American Society of Anesthesiologists(ASA) classification, fracture type, injury to admission time, preoperative waiting time, surgical method, anesthesia type and use of intensive care unit (ICU) fast track. Propensity score matching (PSM) was performed based on age, ASA grade, time from injury to admission, preoperative waiting time, hemoglobin and albumin levels at admission. Clinical outcomes were collected and compared between the two groups, including length of hospital stay, total hospitalization cost and 30-day, 90-day and 1-year mortality rates, and postoperative complications. Multivariate logistic regression analyses were conducted to identify influencing factors for 1-year mortality in geriatric patients with hip fracture. Results: Baseline data showed statistically significant differences in hemoglobin, albumin and preoperative waiting time between the two groups (all P<0.05). After PSM matching, 69 patients were included in each group, and no significant differences were observed in baseline data between the two groups (all P>0.05). There was no significant differences in 30-day mortality rate (4.3% vs 0, P=0.080), 90-day mortality rate (7.2% vs 1.4%, P=0.095), length of hospital stay [(10.85±4.45)d vs (10.92±3.68)d, P=0.919], total hospitalization cost [(60.9±15.4) thousands yuan vs (59.1±15.4) thousands yuan, P=0.489], postoperative complications [pneumonia (11.6% vs 13.0%, P=0.796), cardio-cerebrovascular complications (11.6% vs 8.7%, P=0.573) and delirium (5.7% vs 2.9%, P=0.245)] between the Friday group and the non-Friday group (all P>0.05). However, the 1-year mortality rate was higher in the Friday group than that in the non-Friday group(18.8% vs 4.3%, P=0.008). Multivariate analysis revealed that surgery on Friday (OR=11.222, 95%CI: 2.198-57.291, P=0.004), low hemoglobin levels at admission (OR=0.920, 95%CI: 0.875-0.967, P=0.001), hemiarthroplasty treatment (OR=5.127, 95%CI: 1.308-20.095, P=0.019) and longer surgery duration (OR=0.958, 95%CI: 0.927-0.989, P=0.009) were influencing factors for 1-year mortality in geriatric patients with hip fracture. Conclusions: In the context of multidisciplinary treatment, Friday surgery does not increase short-term mortality, length of hospital stay, total hospitalization cost or incidence of complications in geriatric patients with hip fracture. However, it remains a influencing factor for 1-year mortality in those patients.

Observation of a Strongly Isospin-Mixed Doublet in

ß decay of proton-rich nuclei plays an important role in exploring isospin mixing. The ß decay of ^{26}P at the proton drip line is studied using double-sided silicon strip detectors operating in conjunction with high-purity germanium detectors. The T=2 isobaric analog state (IAS) at 13 055 keV and two new high-lying states at 13 380 and 11 912 keV in ^{26}Si are unambiguously identified through ß-delayed two-proton emission (ß2p). Angular correlations of two protons emitted from ^{26}Si excited states populated by ^{26}P ß decay are measured, which suggests that the two protons are emitted mainly sequentially. We report the first observation of a strongly isospin-mixed doublet that deexcites mainly via two-proton decay. The isospin mixing matrix element between the ^{26}Si IAS and the nearby 13 380-keV state is determined to be 130(21) keV, and this result represents the strongest mixing, highest excitation energy, and largest level spacing of a doublet ever observed in ß-decay experiments.

Worst itch numerical rating scale for prurigo nodularis: a psychometric evaluation.

BACKGROUND: Study TR03 evaluated the safety and efficacy of nalbuphine ER for prurigo nodularis (PN; NCT02174419). OBJECTIVE: We conducted supplementary analyses to assess the psychometric properties of the Worst Itch Numeric Rating Scale (WI-NRS), the TR03 primary endpoint. METHODS: Study TR03 was a double-blind, placebo-controlled, phase 2 trial in PN patients with documented scores ≥5 on the WI-NRS (0 [no itch]-10 [worst itch imaginable]) on ≥5 of 7 days before baseline. Using TR03 data, the WI-NRS's psychometric properties, including reliability, validity and ability to detect change, were evaluated. A responder threshold was estimated to facilitate interpretation of WI-NRS score changes. RESULTS: Amongst 62 treated patients, improvements in mean [SD] (median) WI-NRS scores were observed between baseline (8.2 [1.21] (8.1)) and week 10 (5.8 [2.43] (6.0)). The WI-NRS had an intraclass correlation coefficient of 0.96 (95% confidence interval, 0.93-0.98) in 42 patients who had stable Itch verbal rating scale (VRS) scores from week 9-10, supporting strong test-retest reliability. Construct validity was supported, with strong correlations at week 10 with Average Itch NRS (r = 0.87) and Itch VRS single-day/weekly mean scores (r = 0.81/0.89) and moderate correlations with ItchyQoL™ total/domain scores (r = 0.41-0.43). The WI-NRS discriminated between predefined severity subgroups based on the Itch VRS and detected changes in itching severity (effect-size estimate: -2.05; standardized response mean: -1.21). An anchor-based threshold based on a two-category improvement in the single-day Itch VRS suggests a responder threshold of ≥3.8 points (~40% improvement). CONCLUSIONS: The WI-NRS demonstrates good measurement properties, supporting its use in evaluating treatment change in PN.

[Analysis of experience in diagnosis and treatment of fetal goiter in patients with Graves' disease complicated with pregnancy].

This article reported the clinical diagnosis and treatment experience of two cases of fetal goiter in Graves' disease (GD) complicated with pregnancy. Two GD patients took antithyroid drugs regularly during pregnancy and their thyroid functions were well controlled, but the levels of thyrotropin receptor antibody (TRAb) of the two cases were still above the upper limit in the second and third trimester. Two fetuses had fetal goiter in the middle and late stages of pregnancy. After continuously controlling maternal thyroid function and closely monitoring fetal ultrasound, there was no aggravation of the fetal goiter, and the delivery went smoothly. One case had neonatal hyperthyroidism. It is suggested that although the thyroid function was well controlled during pregnancy in patients with GD, the high level of serum TRAb still needs to be alert to the occurrence of fetal goiter, and fetal ultrasound is the most direct non-invasive monitoring method.

[Comparative study of gap balancing and measured resection technique in patients receiving staged bilateral total knee arthroplasty].

Objective: To compare the clinical outcomes of staged total knee arthroplasty (TKA) performed on both knees in the same patient using gap balancing (GB) and measured resection (MR) techniques, respectively. Methods: The clinical data of 57 patients undergoing bilateral staged TKA at the Xi'an Jiaotong University Affiliated Honghui Hospital from July 2018 to January 2020 were analyzed. Using the random number table, MR or GB technique was selected when patients underwent primary TKA, and contralateral procedure was done with another technique. The procedures were performed by one chief surgeon, and the same prosthesis was chosen for all the procedures. The two osteotomy techniques for TKA were compared in terms of surgical status, radiographic data, functional recovery and satisfaction rate. Results: Total of 57 patients, including 16 males and 41 females, were included in the study with a mean age of (68.5±4.6) years (59-79 years) at primary TKA. All patients were followed up for (29.6±4.5) months (22-39 months). The interval between the two procedures was (4.7±3.0) months (0.5-12.0 months). Postoperative drainage was less in the GB side when compared with that in the MR side [(93.6±22.2) ml vs (109.9±36.9) ml, P=0.003]. At the 1-month postoperative follow-up, the visual analogue scale (VAS) of pain was lower on the GB side (3.0±0.8) than on the MR side (3.5±1.2), the range of motion (ROM) was higher on the GB side (105.7°±8.2° vs 100.2°±7.5°), the Knee Society Score (KSS) was higher on the GB side (78.5±5.4 vs 74.2±6.3), and the Western Ontario and McMaster University (WOMAC) score was lower on the GB side (35.4±5.5 vs 38.0±6.3), there were significant differences in the up-mentioned indexes between the two groups (all P<0.05). However, the repeated-measures analysis of variance indicated that there was no significant difference in VAS score, ROM, KSS score and WOMAC score between the two techniques (all P>0.05). The satisfactory rate of GB technique was 84.2%(48/57), ant it was 86.0%(49/57) with MR technique (P=0.446). There was also no significant difference between the two techniques in terms of complications (P=0.754). Conclusion: Both the GB and MR technique result in good knee function with similar clinical outcomes in patients receiving TKA in both knees for osteoarthritis without significant deformity.

[Analysis on prevalence and epidemic risk of animal plague in different ecological plague foci in Inner Mongolia Autonomous Region].

The risk of plague epidemics and relapse of various types of plague foci persists in Inner Mongolia Autonomous Region. For Marmota sibirica plague foci, the animal plague has not been found but antibody has been detected positive. Nowadays, Marmota sibirica has been increasing in population and distribution in China. In bordering countries Mongolia and Russia, the animal plague has been continuously prevalent. For Spermophilus dauricus plague foci, the animal plague has been taken place now and then. Compared to the above foci, the animal plague is most prevalent in Meriones unguiculatus plague foci and frequently spread to humans. Due to higher strain virulence and historical disaster in Marmota sibirica plague foci and Spermophilus dauricus plague foci, plague prevention and control should be strengthened on these foci. In addition to routine surveillance, epidemic dynamics need to be further monitored in these two foci, in order to prevent their relapse and spread to humans.

[Study on DNA methylation in HEB cells exposed to PM(2.5) by application of methylation chip technology].

Objective: To screen the differential methylation sites, genes and pathways of air pollution fine particles (PM(2.5)) on human bronchial epithelial (HBE) cells by methylation chip and bioinformation technology, so as to provide scientific basis for further study of the toxicological mechanism of PM(2.5) on HBE cells. Methods: In August 2020, HBE cells were infected with 10 µg/ml and 50 µg/ml PM(2.5) aqueous solution for 24 h, namely PM(2.5) 10 µg/ml exposure group (low dose group) and PM(2.5) 50 µg/ml exposure group (high dose group) ; uninfected HBE cells were used as control group. The DNA fragments were hybridized with the chip, the chip scanned and read the data, analyzed the data, screened the differential methylation sites, carried out GO analysis and KEGG analysis of the differential methylation sites, and analyzed the interaction relationship of the overall differential methylation sites by functional epigenetic modules (FEMs). Results: Compared with the control group, 127 differential methylation sites were screened in the low-dose group, including 89 genes, including 55 sites with increased methylation level and 72 sites with decreased methylation level. The differential methylation sites were mainly concentrated in the Body region and UTR region. Compared with the control group, 238 differential methylation sites were screened in the high-dose group, including 168 genes, of which 127 sites had increased methylation level and 111 sites had decreased methylation level. The differential heterotopic sites were mainly concentrated in the Body region and UTR region. Through FEMs analysis, 8 genes with the most interaction were screened, of which 6 genes had significant changes in methylation level. MALT1 gene related to apoptosis was found in the heterotopic site of methylation difference in low-dose group; PIK3CA and ARID1A genes related to carcinogenesis were found in the heterotopic sites of methylation difference in high-dose group; TNF genes related to tumor inhibition were found in the results of FEMs analysis. Conclusion: After PM(2.5) exposure to HBE cells, the DNA methylation level is significantly changed, and genes related to apoptosis and carcinogenesis are screened out, suggesting that the carcinogenic mutagenic effect of PM(2.5) may be related to DNA methylation.

The biological characters of Bmelav-like genes in the development of Bombyx mori.

The ELAV/Hu family is a conserved multigene family of pan-neuronal RNA-binding protein involved in post-transcriptional regulation in metazoans. In Drosophila, three members of this family, ELAV, RBP9 and FNE, are involved in neuronal differentiation, gene expression regulation and so on. This family is less well characterized in Bombyx mori. Two orthologs BmELAV-like-1 (BmEL-1) and BmELAV-like-2 (BmEL-2) share 55%-71% and 47%-62% identity with that of in Drosophila and humans, respectively. Bmel-1 is ubiquitously expressed while Bmel-2 is expressed in the head and ovaries specifically. Proteins encoded by both genes are localized in nuclear and cytoplasm. The weight of body, cocoon, pupae and cocoon shell are differently affected in Bmel-1- /-2- mutants created using CRISPR/Cas9 technology. Mutations of both genes increase the expression of four silk protein genes, Fib-L, Fib-H, P25 and Ser-1. In addition, the oviposition ability of Bmel-2- females is decreased. This study not only provides valuable insights into the functional roles of Bmelav-like genes in the growth, cocoon characters and regulation of silk protein genes expression, but also provides useful information for silkworm variety breeding.

[Effect of glucose on Akt2 mRNA and methylation level and the association between early-pregnancy Akt2 mRNA level in peripheral blood and pre-pregnancy BMI and GDM].

Objective: To explore the effect of glucose on Akt2 gene methylation and mRNA level in the trophoblast cell line HTR8/SVneo and the association between first-trimester Akt2 mRNA level in peripheral blood and pre-pregnancy body mass index (BMI) and gestational diabetes mellitus (GDM). Methods: The cell model of intrauterine hyperglycemia in pregnant women with GDM was established, and divided into 5 groups based on the different glucose concentrations (2.5, 5.0, 10.0, 25.0, and 40.0 mmol/L). The mRNA levels of Akt2 gene were detected by real-time quantitative PCR, and the methylation levels of Akt2 gene promoter region were detected by mass spectrometry. According to pre-pregnancy BMI and diagnosis of GDM, 60 pregnant women who had given birth at Peking University First Hospital during December 2014 to July 2016 were classified into overweight non-GDM group, overweight GDM group, obese non-GDM group and obese GDM group. Real-time quantitative PCR analyses were used to detect the levels of Akt2 mRNA in first-trimester peripheral blood of the 4 groups. Results: (1) Level of Akt2 mRNA significantly rose with the glucose concentration of medium increased, showing concentration dependency (all P<0.05). Compared with the 25.0 mmol/L group, the following methylation levels changed significantly (all P<0.05): cytosine-phosphate-guanine (CpG) 10, CpG23, and CpG24.5 of Akt2 gene promoter region in the 5.0 mmol/L group, CpG23 and CpG24.5 in the 2.5 mmol/L group, and CpG10 in the 10.0 mmol/L group. Compared with the 5.0 mmol/L group, CpG10 in the 40.0 mmol/L group showed methylation change (P<0.05). (2) Compared with the overweight non-GDM group [1.04(0.90~1.26)], overweight GDM group [2.10(1.85~2.28)] and obese GDM group [1.68(0.82~2.43)] all had higher Akt2 mRNA levels and the differences were statistically significant (all P<0.05). Compared to obese GDM group [1.68(0.82~2.43)], the level of Akt2 mRNA was higher in overweight GDM group [2.10(1.85~2.28)] and lower in obese non-GDM group [1.00(0.71~2.17)], but the differences were not statistically significant (all P>0.05). Conclusions: Glucose might affect Akt2 mRNA level by changing the methylation of Akt2 gene promoter region, and the change might appear in the first trimester of pregnant women with GDM, especially for women with lower pre-pregnancy BMI.

[Analysis of prognosis-related factors in patients with hepatitis B virus-related acute-on-chronic liver failure].

Objective: To investigate the prognosis-related factors and its predictive value in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). Methods: Sixty-three cases with HBV-ACLF were enrolled. According to the prognosis of 4-weeks, patients were divided into survival and death group. Univariate and multivariate analyses were performed on the clinical data of the two groups of patients to screen the risk factors affecting prognosis, evaluate its predictive value, and compare them with the MELD score, CTP score, and CLIFACLF score. The data were analyzed using t-test, Mann-Whitney U test, χ (2) test. Multiple logistic regression analysis was used for multiple risk factors. Results: There were 63 cases with HBV-ACLF, with 16 cases (25.40%) in the 4-week survival group, and 47 cases (74.60%) in the death group. The survival group age was 38.38 ± 14.50 years, which was significantly lower than the age of the death group 52.28 ± 12.51 years (P < 0.001). The survival group alpha-fetoprotein (AFP) level was 91.21 (8.38 ~ 154.10)µg/L, which was significantly higher than the level of the death group [12.60 (5.70 ~ 33.80) µg/L, P = 0.039]. The survival group alanine aminotransferase (ALT) level was 925.65 (523.43 ~ 1 364.80) U/L, which was much higher than that of the death group [371.60 (117.30 ~ 895.30) U/L, P = 0.040]. The survival group serum sodium level was (136.59 ± 4.03) mmol /L, which was significantly higher than the level of the death group [(132.22 ± 6.37) mmol/L, P = 0.013]. The survival group ascites severity level was much lower than that of the death group (P = 0.008). The survival group creatinine level was 56.50(49.43 ~ 86.25) µmol/L, which was much lower than the level of the death group [86.20 (68.00 ~ 143.00) µmol/L, P = 0.003]. Multivariate logistic regression analysis showed that ascites (OR = 0.470, 95% CI: 0.226 ~ 0.977) and age (OR = 0.941, 95% CI: 0.888 ~ 0.996) were risk factors affecting the HBV-ACLF prognosis. The area under the curve predicted liver failure prognostic score for ascites and age was 0.821, and the sensitivity and specificity were 68.8% and 87.2%, which was higher than the area under the curve predicted by the MELD score, CTP score, and CLIFACLF score, respectively. Conclusion: Age and ascites can be used to predict the clinical outcome in patients with HBV-ACLF. Younger patients without ascites have a higher survival rate at 4-weeks, but older patients with ascites are more likely to have a lower survival rate.

[Determination of Three Types of New Psychoactive Tryptamines in Blood by QuEChERS Combined with UPLC-MS/MS].

ABSTRACT: Objective To establish a method combining QuEChERS and ultra-high liquid chromatography-tandem mass spectrometry （UPLC-MS/MS） for rapid screening and testing of three types of new psychoactive tryptamines in human blood： 5-MeO-DALT, 5-MeO-MiPT and 5-MeO-DiPT. Methods The effects of the type of extractant, the type and dosage of salting-out agent, and the dosage of adsorbent on the test results of the three tryptamines were investigated. Blood samples were processed by QuEChERS method and then determined by UPLC-MS/MS. Results The linear relationships of 5-MeO-DALT, 5-MeO-MiPT and 5-MeO-DiPT in human blood were good in the range of 0.5-100, 0.5-100 and 0.2-100 ng/mL, respectively, with their coefficients higher than 0.99. The limits of detection （LODs） were 0.1-0.2 ng/mg. The recoveries ranged from 84.86% to 94.57%. Intra-day and inter-day precisions were good. Conclusion The method is simple, rapid, easy to operate and has a high recovery. It is suitable for the qualitative and quantitative study of tryptamines in blood and can provide the reference for public security organs to deal with related cases.

Pan-Asian adapted ESMO Clinical Practice Guidelines for the management of patients with intermediate and advanced/relapsed hepatocellular carcinoma: a TOS-ESMO initiative endorsed by CSCO, ISMPO, JSMO, KSMO, MOS and SSO.

The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of hepatocellular carcinoma (HCC) was published in 2018, and covered the diagnosis, management, treatment and follow-up of early, intermediate and advanced disease. At the ESMO Asia Meeting in November 2018 it was decided by both the ESMO and the Taiwan Oncology Society (TOS) to convene a special guidelines meeting immediately after the Taiwan Joint Cancer Conference (TJCC) in May 2019 in Taipei. The aim was to adapt the ESMO 2018 guidelines to take into account both the ethnic and the geographic differences in practice associated with the treatment of HCC in Asian patients. These guidelines represent the consensus opinions reached by experts in the treatment of patients with intermediate and advanced/relapsed HCC representing the oncology societies of Taiwan (TOS), China (CSCO), India (ISMPO) Japan (JSMO), Korea (KSMO), Malaysia (MOS) and Singapore (SSO). The voting was based on scientific evidence, and was independent of the current treatment practices, the drug availability and reimbursement situations in the individual participating Asian countries.

The Diagnostic Value of Serum ST8SIA6-AS1 as Biomarker in Hepatocellular Carcinoma.

BACKGROUND: Long noncoding RNA (lncRNA) is a promising serum biomarker in cancer diagnosis. However, literature on the diagnostic value of the lncRNA for hepatocellular carcinoma (HCC) is scant. METHODS: The expression of ST8SIA6-AS1 in serum and HCC cell lines was detected by real-time PCR (RT-PCR). We then analyzed the relationship between clinicopathological characteristics and serum ST8SIA6-AS1 expression. In addition, we performed the receiver operating characteristic (ROC) curve and area under curve (AUC) analyses to determine the diagnostic ability of serum ST8SIA6-AS1. RESULTS: Our data demonstrated an up-regulation of ST8SIA6-AS1 in 77 HCC patients and HCC cell lines. Besides, clinicopathological analysis revealed that ST8SIA6-AS1 corresponds with tumor stages and metastasis, thus might be used for monitoring the HCC progress. Importantly, the ROC analysis demonstrated that ST8SIA6-AS1 yields a superior diagnostic ability. Compared with α-fetoprotein (AFP) alone, a combination of ST8SIA6-AS1 and AFP may achieve more reliable diagnostic results. CONCLUSIONS: Together, our results demonstrate that serum ST8SIA6-AS1 is a promising serum diagnostic bio-marker for HCC.

Associations among menopausal status, menopausal symptoms, and depressive symptoms in midlife women in Hunan Province, China.

Objective: This study aimed to determine the associations among menopausal status, menopausal symptoms, and depressive symptoms in midlife women in Hunan, China.Methods: A secondary analysis involving 3199 women aged 40-55 years was performed based on data from the Women Health Needs Survey 2018 in Hunan Province, central south China. The depressive symptoms were determined using the 9-item Patient Health Questionnaire. The menopausal symptoms were assessed using the Kupperman Menopausal Index. Demographic characteristics and menopausal status were measured using self-administered questionnaires.Results: The prevalence of depressive symptoms was 19.3%. The three most common menopausal symptoms were insomnia (48.0%), fatigue (42.7%), and mood swing (39.8%). The increase in depressive symptoms was significantly associated with menopausal status and menopausal symptoms. After controlling for demographic variables, multivariate logistic regression showed that menopausal transition (odds ratio [OR] = 1.14, 95% confidence interval [95% CI] = 1.12-1.86), postmenopause (OR =1.52, 95% CI = 1.09-2.11), and four menopausal symptoms including mood swing (OR = 1.32, 95% CI = 1.03-1.70), depressive mood (OR = 2.28, 95% CI = 1.79-2.91), palpitations (OR = 1.37, 95% CI = 1.06-1.77), and urinary tract infection (OR = 1.49, 95% CI = 1.16-1.92) were associated with depressive symptoms.Conclusions: Independent of demographic variables, menopausal transition, postmenopause, and four menopausal symptoms (mood swing, depressive mood, palpitations, and urinary tract infection) increase the risk of depressive symptoms.

[Subclinical heart injury in patients receiving hypofractionated radiotherapy after breast conserving surgery: a preliminary analysis of prospective study].

Objective: To evaluate the incidence of early cardiac injury in patients with left-sided breast cancer receiving hypofractionated radiotherapy after breast conserving surgery, and to investigate the correlation between cardiac injury and hypofractionated radiotherapy dose. Methods: We prospectively enrolled 103 breast cancer patients who received whole breast with or without regional nodal irradiation after breast conserving surgery using either deep inspiration breath-hold (DIBH) or free breathing (FB) radiotherapy technique. Cardiac examinations that included N-terminal pro-B-type natriuretic peptide (NT-proBNP), electrocardiogram, and myocardial perfusion imaging were performed routinely before and after radiotherapy. The effects of heart dose, systemic therapy and individual factors (Framingham score) on the incidence of cardiac events were analyzed. Results: The median age was 48 years. The mean dose (Dmean) of the heart, left anterior descending coronary artery (LAD), left ventricular (LV), and right ventricular (RV) were 4.0, 16.9, 6.3, and 4.4 Gy, respectively. With a median follow-up of 13.4 months, no patient had clinical cardiac abnormalities. The incidence rates of subclinical cardiac events at 1- 6- and 12-month were 23.5%, 31.6%, and 41.3%, respectively. The DIBH group had a lower mean dose, maximum dose, and V5-V40 in the heart, LAD, LV, and RV than the FB group (P<0.001). Univariate analysis showed an increased incidence of subclinical cardiac events with heart Dmean >4 Gy, LAD V40 > 20%, LV Dmean >6 Gy, RV Dmean >7 Gy, or cumulative doses of anthracycline or taxane > 300 mg/m(2) (All P<0.05). Anti-HER2 targeted therapy, endocrine therapy and Framingham score were not associated with the incidence of subclinical cardiac events (all P>0.05). Multivariate analysis demonstrated that Dmean of LV and RV were independently associated with the increased incidence of subclinical cardiac events. Conclusions: Early subclinical heart injury are found in patients with left-sided breast cancer after hypofractionated radiotherapy. The increased incidence of subclinical cardiac events after radiotherapy is positively associated with the cardiac radiation doses.

[Progress in the clinical diagnosis and treatment of hepatic vascular diseases].

The liver has a very special dual blood supply, including the portal vein (65%~75%) and hepatic artery (25%~35%). The hepatic veins returns blood to the systemic circulation via the portal vein, and hepatic artery after hepatic sinusoidal confluence. The lesions on the hepatic vein and its branches can cause ischemia and hypoxia or obstruction of the drainage system, portal hypertension, upper gastrointestinal variceal bleeding, hepatic encephalopathy, and so on. Clinically, hepatic vascular diseases are relatively rare, so the diagnosis and treatment are relatively difficult. Herein, we review the diseases related to the hepatic vascular system.

[Value of serum alpha-fetoprotein for the prognostic evaluation of hepatitis B virus-related acute-on-chronic liver failure treated with artificial liver].

Objective: To investigate the value of alpha-fetoprotein (AFP) level on survived hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) patients treated with artificial liver. Methods: Clinical indicators of HBV-ACLF patients who were previously treated with plasma exchange-based artificial liver at our department were retrospectively collected. The difference of serum AFP level between the survival and the death group was compared at 30, 90 and 180 days after artificial liver treatment. The ROC curves of the subjects were plotted, and the sensitivity and specificity of AFP for the survival prediction of the patients at 30, 90 and 180 days after artificial liver surgery were calculated. AFP was divided into a high AFP group and a low AFP group using median value. AFP and postoperative survival predictive value at 30, 90, and 180 days were analyzed. Results: A total of 93 cases were included in this study. The AFP of the survival group at 30, 90, and 180 days was (231.0 ± 286.2) ng / ml, (237.69 ± 297) ng / ml, (229.44 ± 286.46) ng/ml, and the death group was (76.4 ± 104.7) ng/ml, (103.13 ± 116.99) ng / ml, (136.34 ± 2.9.29) ng/ml, respectively. AFP of the death group was significantly lower than the corresponding survival group (P < 0.05). Receiver operating characteristic (ROC) curve analyses indicated that the area under the curve (AUC) and its 95% confidence interval at 30, 90, and 180 days after artificial liver surgery were 0.739 (0.611 ~ 0.867), 0.675 (0.550 ~ 0.80), 0.653 (0.524 ~ 0.781), respectively. The median serum AFP value was 110 ng/ml, and the survival analysis showed that the survival time of the high AFP group was significantly higher than the low AFP group at 30 d (P = 0.01), 90 d (P = 0.04) and 180 d (P = 0.03) after artificial liver surgery. Conclusion: Serum AFP can be used as a predictor of survival for HBV-ACLF patients after artificial liver therapy and its clinical value needs to be further verified by the larger sample size.

[Effect of p38MAPK gene silencing on expression of oncogenes and apoptotic genes induced by PM(2.5) in hepatocytes].

Objective: To study the effect of p38 mitogen-activated protein kinase (MAPK) gene silencing on expression of apoptotic genes and oncogenes in hepatocytes treated with PM(2.5). Methods: From June to September 2019, according to the p38MAPK gene mRNA sequence provided by GenBank, three interfering sequences were designed and synthesized, ligated into PLVX-shRNA2-puro after annealing, and the recombinant lentiviral vector was transfected into L02 hepatocytes. The p38MAPK silencing cells were identified by real-time fluorescent quantitative PCR and western blotting. The normal L02 cells and p38MAPK silencing cells were treated with 50 µg/mL PM(2.5) water soluble solution, 10 µmol/L positive control Cr(6+), and a blank control group was set up, the treatment time was 24 h. The mRNA levels of oncogenes (c-fos, c-myc, k-ras) , tumor suppressor gene (p53) and apoptotic genes (Caspase-3, Caspase-8, Caspase-9) were detected by real-time PCR. The protein levels of oncogenes and apoptotic genes were detected by Western blotting. Results: The expression levels of p38MAPK mRNA and protein in p38MAPK gene silencing cells were significantly lower than those in L02 hepatocytes (P<0.05) , and the p38MAPK gene silencing cell line was successfully constructed. Compared with the blank control group, the expression levels of the oncogenes c-fos, c-myc, k-ras and the apoptosis genes Caspase-3, Caspase-8 and Caspase-9 increased, the expression level of tumor suppressor gene p53 decreased in the L02 hepatocyte group treated with PM(2.5) water soluble matter, and the differences were statistically significant (P<0.05) . Compared with the L02 hepatocytes group treated with PM(2.5) water soluble matter, the expression levels of the oncogenes c-fos, c-myc, k-ras and apoptosis genes Caspase-3, Caspase-8 and Caspase-9 decreased, the expression level of tumor suppressor gene p53 increased in the p38MAPK gene silencing cells group treated with PM(2.5) water soluble matter, and the differences were statistically significant (P<0.05) . Conclusion: PM(2.5) has effects on the expression of oncogenes, tumor suppressor genes and apoptotic genes in L02 hepatocytes, while p38MAPK gene silencing can inhibit the effects of PM(2.5) on L02 hepatocytes.
