ABSTRACT
Objective: To assess the prevalence, risk factors and treatment of anemia in patients with chronic kidney disease (CKD). Methods: A descriptive method was used to analyze the prevalence and treatment of anemia in CKD patients based on regional health data in Yinzhou District of Ningbo during 2012-2018. The multivariate logistic regression analysis was used to identify independent influence factors of anemia in the CKD patients. Results: In 52 619 CKD patients, 15 639 suffered from by anemia (29.72%), in whom 5 461 were men (26.41%) and 10 178 were women (31.87%), and anemia prevalence was higher in women than in men, the difference was significant (P<0.001). The prevalence of anemia increased with stage of CKD (24.77% in stage 1 vs. 69.42% in stage 5, trend χ2 test P<0.001). Multivariate logistic regression analysis revealed that being women (aOR=1.57, 95%CI: 1.50-1.63), CKD stage (stage 2: aOR=1.10, 95%CI: 1.04-1.16;stage 3: aOR=2.28,95%CI: 2.12-2.44;stage 4: aOR=4.49,95%CI :3.79-5.32;stage 5: aOR=6.31,95%CI: 4.74-8.39), age (18-30 years old: aOR=2.40,95%CI: 2.24-2.57, 61-75 years old: aOR=1.35,95%CI:1.28-1.42, ≥76 years old: aOR=2.37,95%CI:2.20-2.55), BMI (<18.5 kg/m2:aOR=1.29,95%CI: 1.18-1.41;23.0-24.9 kg/m2:aOR=0.79,95%CI: 0.75-0.83;≥25.0 kg/m2:aOR=0.70,95%CI: 0.66-0.74), abdominal obesity (aOR=0.91, 95%CI: 0.86-0.96), chronic obstructive pulmonary disease (aOR=1.15, 95%CI: 1.09-1.22), cancer (aOR=3.03, 95%CI: 2.84-3.23), heart failure (aOR=1.44, 95%CI: 1.35-1.54) and myocardial infarction (aOR=1.54, 95%CI:1.16-2.04) were independent risk factors of anemia in CKD patients. Among stage 3-5 CKD patients with anemia, 12.03% received iron therapy, and 4.78% received treatment with erythropoiesis-stimulating agent (ESA) within 12 months after anemia was diagnosed. Conclusions: The prevalence of anemia in CKD patients was high in Yinzhou. However, the treatment rate of iron therapy and ESA were low. More attention should be paid to the anemia management and treatment in CKD patients.
ABSTRACT
A 3-year-old boy presented with bluish patch and scattered blue spots on the left side of his face. After several sessions of laser treatment, the azury patch in the periorbital area became even darker. Histopathology showed many bipolar, pigment-laden dendritic cells scattered in the papillary and upper reticular dermis. Immunohistochemically, these cells were positive for S100, SOX-10, melan-A, P16, and HMB-45. The positive rate of Ki-67 was less than 5%. Finally, the lesion was diagnosed with nevus of Ota concurrent with common blue nevus. Therefore, for cases of the nevus of Ota with poor response to laser treatment, the possible coexisting diseases should be suspected.

Objective:To investigate the effect of miRNA (miR) -193b-5p on melanogenesis and its possible mechanisms.Methods:Human primary melanocytes were isolated from discarded normal foreskin tissues of healthy males after circumcision, and cultured in vitro. miR-NC mimics (miR-NC mimic group) and miR-193b-5p mimics (miR-193b-5p mimic group) were transfected into human primary melanocytes and human MNT1 melanoma cells, separately. After transfection, real-time quantitative PCR (RT-qPCR) was performed to determine the overexpression efficiency of miR-193b-5p at 48 hours, Western blot analysis to determine the expression of melanogenesis-related proteins tyrosinase (TYR) and microphthalmia-associated transcription factor (MITF) in human primary melanocytes and human MNT1 melanoma cells at 72 hours, and the melanin content in the above cells was determined by a sodium hydroxide solubilization method at 1 week. The target gene of miR-193b-5p was predicted by using Targetscan algorithms and verified by dual-luciferase reporter assay, and RT-qPCR and Western blot analysis were performed to analyze changes in mRNA and protein expression of the target gene respectively after the overexpression of miR-193b-5p. Two-independent-samples t test was used for comparisons between two groups. Results:In human primary melanocytes and human MNT1 melanoma cells, the miR-193b-5p expression levels were significantly higher in the miR-193b-5p mimic groups than in the miR-NC mimic groups ( t = 65.57, 22.49, respectively, both P < 0.001) , and the melanin content was significantly lower in the miR-193b-5p mimic groups (0.091 ± 0.007, 0.130 ± 0.004, respectively) than in the miR-NC mimic groups (0.117 ± 0.002, 0.188 ± 0.032, t = 5.98, 3.24, P < 0.01, < 0.05, respectively) . Western blot analysis showed that the expression of melanogenesis-related proteins TYR and MITF in both human primary melanocytes and human MNT1 melanoma cells was significantly lower in the miR-193b-5p mimic groups than in the miR-NC mimic groups (all P < 0.01) . TargetScan analysis and dual-luciferase reporter assay revealed a binding site for miR-193b-5p in the 3′ untranslated region of the transcriptional regulator CITED2. After up-regulation of miR-193b-5p expression in human primary melanocytes and human MNT1 melanoma cells, the CITED2 mRNA and protein expression levels significantly decreased compared with the miR-NC mimic groups (all P < 0.05) . Conclusion:miR-193b-5p overexpression can down-regulate the expression of melanogenesis-related proteins TYR and MITF, and then inhibit melanogenesis, which may be related to the targeted inhibition of CITED2 expression.
ABSTRACT
Objective:To report the results of national surveillance on the distribution and antimicrobial resistance profile of clinical bacterial isolates from bloodstream infections in China in 2021.Methods:The clinical bacterial strains isolated from blood culture from member hospitals of Blood Bacterial Resistant Investigation Collaborative System (BRICS) were collected during January 2021 to December 2021. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical Laboratory Standards Institute (CLSI). WHONET 5.6 was used to analyze data.Results:During the study period, 11 013 bacterial strains were collected from 51 hospitals, of which 2 782 (25.3%) were Gram-positive bacteria and 8 231 (74.7%) were Gram-negative bacteria. The top 10 bacterial species were Escherichia coli (37.6%), Klebsiella pneumoniae (18.9%), Staphylococcus aureus (9.8%), coagulase-negative Staphylococci (6.3%), Pseudomonas aeruginosa (3.6%), Enterococcus faecium (3.6%), Acinetobacter baumannii (2.8%), Enterococcus faecalis (2.7%), Enterobacter cloacae (2.5%) and Klebsiella spp (2.1%). The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococcus aureus were 25.3% and 76.8%, respectively. No glycopeptide- and daptomycin-resistant Staphylococci was detected; more than 95.0% of Staphylococcus aureus were sensitive to ceftobiprole. No vancomycin-resistant Enterococci strains were detected. The rates of extended spectrum B-lactamase (ESBL)-producing isolated in Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis were 49.6%, 25.5% and 39.0%, respectively. The prevalence rates of carbapenem-resistance in Escherichia coli and Klebsiella pneumoniae were 2.2% and 15.8%, respectively; 7.9% of carbapenem-resistant Klebsiella pneumoniae was resistant to ceftazidime/avibactam combination. Ceftobiprole demonstrated excellent activity against non-ESBL-producing Escherichia coli and Klebsiella pneumoniae. Aztreonam/avibactam was highly active against carbapenem-resistant Escherichia coli and Klebsiella pneumoniae. The prevalence rate of carbapenem-resistance in Acinetobacter baumannii was 60.0%, while polymyxin and tigecycline showed good activity against Acinetobacter baumannii (5.5% and 4.5%). The prevalence of carbapenem-resistance in Pseudomonas aeruginosa was 18.9%. Conclusions:The BRICS surveillance results in 2021 shows that the main pathogens of blood stream infection in China are gram-negative bacteria, in which Escherichia coli is the most common. The MRSA incidence shows a further decreasing trend in China and the overall prevalence of vancomycin-resistant Enterococci is low. The prevalence of Carbapenem-resistant Klebsiella pneumoniae is still on a high level, but the trend is downwards.

Conclusion:LEF1 and CTNNB1 can regulate the proliferation and G 2 phase arrest of esophageal cancer cells after radiation intervention by mediating the Wnt signaling pathway, and improve the radiation resistance of esophageal cancer cells by inhibiting cell apoptosis.
ABSTRACT
Objective:To explore the experience and true feeling of home care aides during nighttime caring at the first beginning stage of this program, find the difficulty of it and provide constructive suggestions for improvement.Methods:Semi-structed interviews were used to collect the data of 16 home care aides who were taking part in nighttime caring. Colaizzi phenomenological analysis was used to process and analyze the data.Results:Three themes were extracted by classifying and analyzing the details of the interview: the service content of nighttime care was easy, but had many constraint conditions; the caregivers had diversified emotional experience during nighttime care; the elderly would like to enjoy nighttime care, but they were unwilling to pay by themselves.Conclusions:Nighttime caring project deepens the service content of home-based care. But the nighttime care project needs to be standardized. We should establish risk prevention measures to guarantee the benefit and security of both home caregivers and care-receivers, changing the opinions of consumption among the elderly, increasing the amount of subsidy to enlarge the expansion of nighttime care and improve the equality of this caring program.

ABSTRACT
MicroRNAs (miRNAs) regulate gene expression and are biomarkers for coronary atherosclerosis (AS). A novel miRNA-mRNA regulation network of coronary AS still needs to be disclosed. The aim of this study was to analyze potential mRNAs in coronary AS patients and the role of their upstream miR-491-5p in vascular smooth muscle cells (VSMCs). We first confirmed top ten mRNAs according to the analysis from Gene Expression Omnibus database (GSE132651) and examined the expression levels of them in the plaques and serum from AS patients. Five mRNAs (UBE2G2, SLC16A3, POLR2C, PNO1, and AMDHD2) presented significantly abnormal expression in both plaques and serum from AS patients, compared with that in the control groups.Subsequently, they were predicted to be targeted by 11 miRNAs by bioinformatics analysis. Among all the potential upstream miRNAs, only miR-491-5p was abnormally expressed in the plaques and serum from AS patients. Notably, miR-491-5p overexpression inhibited viability and migration, and significantly increased the expression of contractile markers (α-SMA, calponin, SM22α, and smoothelin) in VSMCs. While silencing miR-491-5p promoted viability and migration, and significantly suppressed the expression of α-SMA, calponin, SM22α, and smoothelin. Overall, miR-491-5p targeted UBE2G2, SLC16A3, and PNO1 and regulated the dysfunctions in VSMCs.
ABSTRACT
Objective:To observe the transparency and tissue structure changes of human corneal stromal lenticules after long-term cryopreservation and explore a simple and feasible method for long-term effective preservation of corneal stromal lenticules.Methods:Two hundred samples of intact human corneal stromal lenticules from 200 eyes were obtained during femtosecond laser small-incision lenticule extraction (SMILE) in Hainan Eye Hospital, Zhongshan Ophthalmic Center from 2013 to 2020.The samples were divided into 1-month, 24-month, 60-month and 80-month group and were stored in an ultra-low temperature freezer for 1, 24, 60 and 84 months respectively at -80 ℃ according to grouping, with 50 samples in each group.Transmittance of the corneal lenticules at wavelength of 300-800 nm was measured with an ultra-micro spectrophotometer and every lenticule was measured for 10 times with a 50 nm interval.The histomorphology and collagen fiber structure of the corneal lenticules were examined by hematoxylin-eosin staining and Masson staining, respectively.The arrangement of collagen fibers and ultrastructure changes of keratocytes in the samples were inspected with a transmission electron microscope.The apoptosis rate of keratocytes was determined by TUNEL staining.The study protocol was approved by an Ethics Committee of Hainan Eye Hospital at Zhongshan Ophthalmic Center (No.2013-003). This study complied with the Declaration of Helsinki.Written informed consent was obtained from each subject before surgery.Results:The corneal lenticules were clear and intact in all groups and no significant difference in the transmittance within 450-800 nm wavelength was seen among the 4 groups (all at P>0.05). Masson staining revealed that the collagen fibers in the lenticules were neatly arranged and tightly packed in the 1-month group.In the 24-month group, interfibrous vacuoles were found in some collagen fibers.The arrangement of the collagen fibers was loose and more vacuoles were displayed in the 60-month group, and the loss of some collagen fibers appeared and the lenticules were thinned in the 84-month group.It was found through hematoxylin-eosin staining that the morphological changes of corneal stromal lenticules corresponded to the alterations of collagen fibers.Transmission electron microscopy showed that in the 1-month group, the collagen fibers of the corneal stroma lenticules were neatly arranged and regular, and the corneal stromal cells were elongated and spindle-shaped, and the nuclear membrane was intact and the cytoplasm was abundant.In the 24-month group, the collagen fibers showed slightly loose arrangement, and the corneal stromal cells were deformed with incomplete nuclear membrane.In the 60-month group, the collagen fibers were in loose and irregular arrangement, and the nuclei were atrophied and deformed.The 84-month group showed disorganized arrangement of collagen fibers, wrinkled and atrophied corneal stromal cells, discontinuous nucleus membrane and nucleoplasmic lysis.TUNEL staining showed that the percentage of apoptotic corneal cells in lenticules was (87.80±1.17)%, (89.50±1.05)%, (89.30±1.51)% and (90.20±1.47)% in the 1-month, 24-month, 60-month and 84-month groups, respectively, with no statistically significant difference found in overall comparison ( F=4.525, P=0.053). Conclusions:The disorder of collagen fibers and apoptosis of keratocytes occur in the human corneal stromal lenticules till 84 months after cryopreservation, however, the transparency and integrity remain excellent.The ultra-low temperature preservation technique provides an effective and simple solution for long-term storage of human corneal stromal lenticule.

ABSTRACT
OBJECTIVE@#To analyze the correlation of methylation status of dachshund homolog 1 (DACH1) gene in tumor tissues with clinicopathological characteristics and prognosis of patients of esophageal cancer.@*METHODS@#Tumor tissue, paracancerous tissue and normal esophageal mucosal specimens of 104 patients with esophageal cancer were collected. Methylation-specific PCR was used to determine the methylation status of the DACH1 gene. Univariate analysis and multivariate Logistic regression model were used to analyze the correlation between DACH1 methylation status and clinical pathological characteristics of the patients. Kaplan-Meier survival curve was used to analyze the relationship between DACH1 methylation status and prognostic survival of patients.@*RESULTS@#The methylation rate of the DACH1 gene in esophageal cancer tumor tissue was 30.77% (32/104), which was higher than those in adjacent tissues (1.92%) and normal esophageal mucosa (0%) (P 0.05) but tumor differentiation, TNM staging, and lymph node metastasis(P< 0.05). The degree of tumor differentiation, TNM stage, and lymph node metastasis of patients are independent risk factors for the methylation status of the DACH1 gene. By March 2020, 89 of the 104 patients had died. Among them, the median survival foresophageal cancer patients with DACH1 gene methylation was 22 months, which was lower than 34 months of those without DACH1 methylation (P< 0.05).@*CONCLUSION@#Methylation of the DACH1 gene may be involved in the occurrence and progress of esophageal cancer. The degree of tumor differentiation, TNM stage, and lymph node metastasis of patients are independent risk factors for the methylation status of the DACH1 gene. Patients with esophageal cancer but unmethylated DACH1 gene have a longer prognostic survival.

Ischemia-reperfusion (IR) injury is a major cause of clinical emergencies during and after surgical procedures.Propofol protects the heart from cardiovascular IR injury by inhibiting autophagy. MicroRNAs (miRNAs)participate in anesthetic-regulated cardiovascular injury. MiR-20b-5p targets unc-51-like autophagy activatingkinase 1 (ULK1). Its role in propofol-modulated cardiovascular IR injury remains unclear, however. In thisstudy, we used an in vitro model of hypoxia-reoxygenation (HR)-induced injury to human umbilical veinendothelial cells (HUVECs) to determine the protective effect of miR-20b-5p in cells preconditioned withpropofol. We found that miR-20b-5p was significantly higher and ULK1 was lower in propofol-preconditionedHUVECs with HR injury than in HUVECs with HR injury only. Additionally, miR-20b-5p overexpressionincreased cell viability and repressed autophagy and apoptosis more in propofol-preconditioned HUVECs withHR injury than in HUVECs with HR injury only. A luciferase reporter assay confirmed the target reactionbetween miR-20b-5p and ULK1. Overexpression of ULK1 restrained the protective effect of miR-20b-5p inpropofol-preconditioned HUVECs with HR injury. In conclusion, our results indicate that propofol inhibitsautophagic cell death via the miR-20b-5p-ULKI axis and that ULK1 may be a therapeutic target for cardiovascular IR injury
ABSTRACT
Objective:To investigate the effect of self-help cognitive behavioral intervention on the recovery of patients with generalized anxiety disorder.Methods:A total of 123 patients with generalized anxiety disorder were recruited from a comprehensive hospital in Hunan province. The patients were randomly assigned into control group( n=62) and intervention group( n=61) according to random number table. The patients in the control group were received routine treatment alone, while the patients in the intervention group were received routine treatment and WeChat-based self-help cognitive behavioral therapy. The generalized anxiety disorder(GAD-7), self-rating depression scale(SDS), WHO quality of life scale(WHOQOL-BREF), Pittsburgh sleep quality index(PSQI) and medication adherence scale(MARS) were used to measure the anxiety, depression, quality of life, sleep quality and medication compliance at three time points: before intervention (T1), after intervention (T2) and during follow-up (T3). The SPSS 21.0 was used to analyze the data.Mean±standard deviation, frequency and constituent ratio were used to describe the data based on the type of data. Repeated measure ANOVA was used to compare the between-group variation, time effect and interaction effect of two groups at 3 time points. Results:The anxiety score of intervention group at T1, T2, T3 were (12.74± 2.02), (7.13± 1.48), (6.57±1.73) respectively, and the anxiety score of the control group were (12.08±2.11), (11.11±3.27), (10.11±3.33) respectively. Compared with the control group, the score of anxiety in the intervention group was significantly decreased at T2 and T3 ( P<0.05). Compared with control group, the sleep quality and quality of life of intervention group were significantly improved at T2, T3 ( P<0.05), and the medication compliance of the intervention group was significantly improved at T3 ( P<0.05). Conclusion:Self-help cognitive behavioral intervention can decrease anxiety significantly and improve the quality of life, sleep quality, and medication compliance in patients with generalized anxiety disorder.
ABSTRACT
Objective:To investigate the in vitro interaction between antifungals and tacrolimus against Fusarium solani. Methods:According to Clinical and Laboratory Standards Institute(CLSI) M27-Ed4 and M38-A3, 24 strains of Fusarium solani isolated from clinic were used to test the minimal inhibitory concentration (MIC) of the four antifungals.Chessboard microdilution method was used to evaluate the interaction of tacrolimus (FK506) combined with four antifungals in vitro.The study protocol was approved by the Ethics Committee of Hainan Eye Hospital (No.2017-006). Results:The MIC ranges of fluconazole, voriconazole, natamycin and amphotericin B against 24 strains of Fusarium were 64-256 μg/ml, 1-8 μg/ml, 2-8 μg/ml and 1-8 μg/ml, respectively.Tacrolimus combined with fluconazole, voriconazole, natamycin and amphotericin B had synergistic effects on 12.5% (3/24), 4.2% (1/24), 16.7% (4/24) and 29.2% (7/24) Fusarium, respectively.There were no antagonistic effect in this study. Conclusions:Fusarium is sensitive to natamycin in vitro and partly sensitive to amphotericin B and voriconazole.Synergistic effects exist in few strains of Fusarium but no antagonistic effect.
ABSTRACT
Novel Coronavirus Pneumonia (NCP) is a class B infectious disease, which is prevented and controlled according to class A infectious diseases.Recently, children′s NCP cases have gradually increased, and children′s fever outpatient department has become the first strategic pass to stop the epidemic.Strengthening the management of the fever diagnosis process is very important for early detection of suspected children, early isolation, early treatment and prevention of cross-infection.This article proposes prevention and control strategies for fever diagnosis, optimizes processes, prevents cross-infection, health protection and disinfection of medical staff, based on the relevant diagnosis, treatment, prevention and control programs of the National Health and Health Commission and on the diagnosis and treatment experience of experts in various provinces and cities.The present guidance summarizes current strategies on pre-diagnosis; triage, diagnosis, treatment, and prevention of 2019-nCoV infection in common fever, suspected and confirmed children, which provide practical suggestions on strengthening the management processes of children′s fever in outpatient department during the novel coronavirus pneumonia epidemic period.
