Abstract
OBJECTIVE Acute kidney injury (AKI) is difficult to detect in the early stages, yet is commonly associated with sepsis and infectious shock, with pulmonary infection being the most frequent culprit. This study aimed to estimate risk factors and their effects on 28-day survival among sepsis patients with pulmonary infection complicated by AKI and assessed the prognostic values of some detection indicators. PATIENTS AND METHODS From February 2019 to July 2021, the data of 151 patients admitted to the emergency intensive care unit (EICU) of Nanjing First Hospital with pulmonary infection complicated with sepsis were collected in this retrospective study. The patients were categorized into two groups (survivors and non-survivors) depending on the 28-day survival, compared their clinical characteristics, and analyzed the predictors of survival. RESULTS Cox regression analysis revealed that serum cystatin-C level, serum lactate level, and the Acute Physiology and Chronic Health Evaluation II (APACHE II) scoring system were independent risk factors for 28-day survival. In predicting 28-day survival, the area under the receiver operating characteristic curve (ROC) for serum Cystatin-C level, serum lactate level, APACHE II score, and the three combinations was 0.74, 0.67, 0.71, and 0.86, respectively. Accordingly, the sensitivity and specificity of the three indicators of 28-day survival were 87.50% and 66.67%, respectively, which were superior to individual indicators. CONCLUSIONS Sepsis patients with pulmonary infection have a high risk of AKI, and multiple risk factors contribute to this risk. AKI patients may also be adversely affected by a variety of factors, including APACHE II scores, serum Cystatin-C levels, and serum lactate levels, all of which are commonly used to assess the outcomes.

Abstract
PURPOSE/OBJECTIVE(S) To assess the safety and efficacy of intensity-modulated radiotherapy (IMRT) combined with nimotuzumab for patients with locally advanced nasopharyngeal carcinoma (LA-NPC) medically unfit to receive concomitant chemotherapy. MATERIALS/METHODS From 2016.6 to 2020.9, 34 newly diagnosed patients with local-regional advanced NPC medically unfit for concurrent chemoradiation had undergone definitive radiotherapy and were retrospectively evaluated. All patients were treated with IMRT combined treatment modality of nimotuzumab with or without cisplatin-based induction chemotherapy. Nimotuzumab was administered concurrently with IMRT at a weekly dose of 200 mg. Acute and late radiation-related toxicities were evaluated based on the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 during and after IMRT. The Kaplan-Meier method was used for survival analysis. Univariate and multivariate prognostic analyses were performed by using the Cox proportional hazard model. RESULTS The median follow-up time for the entire group was 15 months (range 5 to 55 months). At the time of this analysis, a total of 2 cases developed loco-regional recurrence. In addition, 4 patients developed distant metastasis. There was a total of 5 deaths: 3 patients died from distant metastasis, 1 patient died from the progression of loco-regional disease after recurrence, and the causes of death for the additional 1 case was a nasopharyngeal ulcer and deadly bleeding. The 1-year OS rate of the whole cohort was 87.9%, and the 1-year LFFR, DFFR, and PFS rates were 100%, 91.0%, and 91.0%, respectively. During the period of concurrent nimotuzumab and IMRT, no grade 3-4 hematologic toxicities and dermatitis were observed. Grade 3-4 radiotherapy-related oral mucositis was reported in 7 patients (20.6%). No infusion reaction was observed. No acneiform eruptions were found among these patients. The most commonly observed late complication was xerostomia. The degree of dry mouth in most patients was mild-to-moderate at the time of the last follow-up. Finally, 7 patients developed either unilateral or bilateral hearing impairment. One female patient experienced a nasopharyngeal ulcer and deadly bleeding after 5 months of completion of radiotherapy. CONCLUSION Concurrent nimotuzumab with IMRT for the treatment of LA-NPC was well tolerated, with encouraging survival data, and it could be an effective treatment alternative for patients with LA-NPC medically unfit for concomitant chemotherapy. Further clinical trials are needed to confirm these findings.

Abstract
PURPOSE/OBJECTIVE(S) Recent studies indicate that the novel lymphocyte-C-reactive protein ratio (LCR) is strongly associated with the survival of various tumors, but its prognostic value in nasopharyngeal carcinoma (NPC) is understudied. This study aimed to explore the relationship between the LCR and overall survival (OS) in NPC and to develop a predictive model. MATERIALS/METHODS A total of 841 NPC patients received concurrent chemoradiotherapy (CCRT) were retrospectively enrolled and randomly divided into training cohort (n = 589) and validation cohort (n = 252). Univariate and multivariate Cox analyses were performed to identify variables associated with OS and construct a predictive nomogram. The predictive accuracy of the nomogram was evaluated and independently validated. RESULTS The LCR score differentiated NPC patients into two groups with distinct prognoses (HR = 0.53; 95% CI: 0.32-0.89, P = 0.014). Multivariate analysis showed that age, T stage, N stage, EBV-DNA status, and LCR score were independently associated with OS and a predictive nomogram was developed. The nomogram had a good performance for the prediction of OS [C-index = 0.770 (95% CI: 0.675-0.864)] and outperformed the traditional staging system [C-index = 0.589 (95% CI: 0.385-0.792)]. The results were internally validated using an independent cohort. CONCLUSION The novel nutrition-inflammation marker of LCR could serve as a simplified, affordable, easy-to-obtain, non-invasive, and readily promotive prognostic marker for NPC patients received CCRT, and the LCR-based prognostic nomogram outperformed the conventional staging system in terms of predictive power.

Abstract
Objective: To analyze the incidence and risk factors of ventricular septal defect (VSD) in Qingdao. Methods: A prospective cohort study design was used to include pregnant women who underwent prenatal screening in Qingdao between August 2018 and June 2020 (the whole population coverage). VSD was diagnosed according to the pulse oxygen saturation and heart auscultation, and the final diagnosis was made according to the echocardiography of VSD positive newborns within postnatal day 7. Results: The study included 115 238 live births, among which 388 were diagnosed as VSD, with an incidence of 3.37‰. The results of multivariate logistic regression analysis showed that mother with postgraduate level (OR=1.61, 95%CI: 1.00-2.58, P=0.049) (compared with junior high school and below), preterm birth history (OR=2.90, 95%CI: 1.47-5.70, P=0.002), and pregnancy history of congenital heart disease (OR=5.98, 95%CI: 2.63-14.73, P<0.001) were risk factors for VSD. Compared with female infants, the overall risk of VSD in male infants was relatively low (OR=0.74, 95%CI: 0.60-0.91, P=0.005). Conclusions: The incidence of VSD in Qingdao is 3.37‰. The risk factors of VSD include higher maternal education level, pregnancy history of congenital heart disease and preterm birth history. Moreover, the overall risk of VSD in male infants is low.

Abstract
AIMS We aimed to investigate the association between residential greenness and MetS in older Chinese adults. METHODS Longitudinal data on sociodemographic characteristics and lifestyle were collected from the Shenzhen Healthy Ageing Research (SHARE) cohort. Greenness exposure was assessed through satellite-derived Normalized Difference Vegetation Index (NDVI) values in the 250-m, 500-m, and 1250-m radius around the residential address for each participant. MetS was defined by standard guidelines for the Chinese population. RESULTS A total of 49,893 older Chinese adults with a mean age of 70.96 (SD = 5.26) years were included in the study. In the fully adjusted models, participants who lived in the highest quartile of NDVI250-m, NDVI500-m, and NDVI1250-m had a 15% (odds ratio, OR = 0.85, 95% confidence interval, CI: 0.80-0.90), 12% (OR = 0.88, 95% CI: 0.83-0.93), and 11% (OR = 0.89, 95% CI: 0.85-0.95) lower incidence of MetS, respectively, than those living in the lowest quartile (all p-trend < 0.01). Interactions and subgroup analyses showed that age, sex, smoking status, and drinking status were significant effect modifiers (p-interaction for all NDVI < 0.05). CONCLUSIONS Residential greenness is associated with a lower risk of MetS in Chinese older adults, especially for young older adults, females, non-smokers, and non-drinkers.

Abstract
OBJECTIVE Previous studies on residential green space were inconsistent with blood lipid levels and hyperlipidemia. Thus, our study aims to explore the relationship between urban residential greenness and the blood lipid level and hyperlipidemia of the Chinese elderly population. METHODS A total of 59,865 older adults were collected from the Shenzhen healthy aging Research (SHARE). Blood lipid levels [total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)] were measured. Participants' exposure to residential greenness was measured by the satellite-based normalized difference vegetation index (NDVI). Generalized linear mixed models (GLMMs) and logistic regression were performed to assess the associations of residential greenness with lipid levels and dyslipidemia (high TG, high TC, low HDL-C, and high LDL-C). RESULTS Each per 1 standard deviation (SD) increase in NDVI250-m was associated with a higher HDL-C level (β = 0.003, 95% (confidence interval, CI):0.001-0.005) and lower TG level (β = - 0.005, 95% CI - 0.141-0.121), after fully adjusting for covariates. Each increment in per interquartile range (IQR)-unit increase in NDVI250-m was associated with lower odds of high TG (odds ratio, OR 0.94, 95% CI 0.91-0.97) and low HDL-C (OR 0.96, 95% CI 0.94-0.99). The NDVI250-m has the highest protective effect on the incidence of high TG and low HDL-C, followed by NDVI500-m and NDVI1250-m. Stratified analyses showed that association between residential greenness and hyperlipidemia was modified by sex, age, BMI, household registration, and physical activity. CONCLUSION Higher greenness exposure was beneficially associated with lipid levels and dyslipidemia among Chinese city-dwelling older adults.

Abstract
The combined use of transcriptome and translatome as indicators of gene expression profiles is usually more accurate than the use of transcriptomes alone, especially in cell types governed by translational regulation, such as mammalian oocytes. Here, we developed a dual-omics methodology that includes both transcriptome and translatome sequencing (T&T-seq) of single-cell oocyte samples, and we used it to characterize the transcriptomes and translatomes during mouse and human oocyte maturation. T&T-seq analysis revealed distinct translational expression patterns between mouse and human oocytes and delineated a sequential gene expression regulation from the cytoplasm to the nucleus during human oocyte maturation. By these means, we also identified a functional role of OOSP2 inducing factor in human oocyte maturation, as human recombinant OOSP2 induced in vitro maturation of human oocytes, which was blocked by anti-OOSP2. Single-oocyte T&T-seq analyses further elucidated that OOSP2 induces specific signaling pathways, including small GTPases, through translational regulation. Development of methods for simultaneous single cell analysis of transcription and translation is still underway. Here, Hu et al. develop single-cell transcriptome and translatome dual-omics on human oocytes, which enables them to identify OOSP2 as an induction factor during human oocyte maturation.

Abstract
OBJECTIVES To identify the DNA comethylation patterns associated with sperm DNA fragmentation (SDF) and to explore the potential associations of hub genes with SDF. DESIGN Prospective study. SETTING University-affiliated reproductive medicine center. PATIENT(S) A total of 300 male patients consulting for couple infertility were recruited from the First Affiliated Hospital of Wenzhou Medical University. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Comethylation network analysis based on the genome-wide methylation profile of spermatozoal DNA from 20 men was performed to identify hub modules and genes involved in SDF. Human spermatozoa were used for targeted bisulfite amplicon sequencing (267 men) or droplet digital polymerase chain reaction (45 men). The potential role of Brca1 in DNA damage was explored in mouse GC2 spermatocyte cells. Oxidative damage to spermatocytes was modeled by incubating GC2 cells with H2O2 (25 mM) for 90 minutes. RESULT(S) BRCA1 was identified as a hub gene in SDF. Promoter hypermethylation of BRCA1 was observed in those samples with a high DNA fragmentation index (DFI) compared to those with a low DFI. Concomitantly, BRCA1 mRNA expression was lower in samples with a high DFI than with a low DFI. In the GC2 cell model, Brca1 knockdown reduced cell proliferation and increased sensitivity to oxidative stress. Moreover, it increased double-strand breaks and decreased the protein levels of the DNA repair genes MRE11 and RAD51. CONCLUSION(S) A prominent cluster of comethylated patterns associated with SDF was identified. BRCA1 may be the hub gene involved in sperm DNA damage.

Abstract
UNLABELLED This retrospective analysis of insurance claims evaluated real-world trends in prescription fills among patients treated with balloon kyphoplasty (N = 6,656) or vertebroplasty (N = 2,189) following diagnosis of vertebral compression fracture. Among those with evidence of opioid use, nearly half of patients discontinued or reduced prescription fills relative to pre-operative levels. INTRODUCTION Vertebral compression fractures (VCF) are associated with debilitating pain, spinal misalignment, increased mortality, and increased healthcare-resource utilization in elderly patients. This study evaluated the effect of balloon kyphoplasty (BKP) or vertebroplasty (VP) on post-procedure opioid prescription fills and payer costs in patients with VCF. METHODS This was a retrospective analysis of a large, nationally representative insurance-claims database. Clinical characteristics, opioid prescription patterns, and payer costs for subjects who underwent either BKP or VP to treat VCF were evaluated beginning 6 months prior to surgery through 7-month follow-up that included a 30-day, postoperative medication washout. Patient demographics, changes in opioid utilization, and payer costs were analyzed. RESULTS A total of 8,845 patients met eligibility criteria (75.3% BKP and 24.7% VP) with a mean of age 77 and 74% female. Among the 75% of patients who used opioids, 48.7% of patients discontinued opioid medication and 8.4% reduced prescription fills versus preoperative baseline. Patients who reduced or discontinued prescriptions exhibited a decrease in all-cause payer costs relative to pre-intervention levels, which was a significantly greater change relative to patients with no change, increase, or new start of opioids. CONCLUSIONS Interventional treatment for VCF was associated with decreased or discontinued opioid prescription fills and reduced payer costs in follow-up in a significant proportion of the study population. Reduction of opioid-based harms may represent a previously unrecognized benefit of vertebral augmentation for VCF, especially in this elderly and medically fragile population.

Abstract
OBJECTIVES To comprehensively evaluate the association between BMI and death risk in people aged 65 years and over in Shenzhen, China, and suggest the optimal range of body mass index (BMI) for the older adults. DESIGN A prospective cohort study. SETTING A population-based study of elderly adults in Shenzhen, China. PARTICIPANTS 359044 Shenzhen Healthy Ageing Research participants aged 65 and over with 4682 deaths during a mean of 1.5 years of follow-up were included in this analysis. MEASURES Hazard ratio of all-cause and cause specific mortality risks associated with BMI categories. The association between BMI and all-cause and cause specific mortality were independently estimated by Cox regression model. RESULTS Regardless of gender, BMI of 24 -29.9 kg/m2 was a protective factor for death in all ages, while BMI above 30 kg/m2 was still a protective factor for older adults under 70 years old. Regardless of age, BMI at 24-25.9 kg/m2 was associated with lower mortality in men, while BMI at 26-27.9 kg/m2 was associated with lower mortality in women. For the older adults without chronic diseases, BMI at 24-25.9 kg/m2 was also significantly associated with lower mortality. In the analysis of BMI and cause of death, we also found that BMI of 24-25.9 kg/m2 was significantly associated with the lower mortality from cardiovascular disease, cancer, chronic respiratory disease and digestive system disease in China. CONCLUSION BMI in the range of 24-25.9 kg/m2 may be protective for mortality in Chinese older adults. Additional more large-scale, multicenter and long-term follow-up studies are needed to confirm these findings in different populations.

Abstract
OBJECTIVE To evaluate Deoxyribonucleic acid (DNA) methylation patterns in sperm from men with differential levels of sperm DNA fragmentation index (DFI). DESIGN Prospective study. SETTING University-affiliated reproductive medicine center. PATIENT(S) A total of 278 male patients consulting for couple infertility were recruited from the First Affiliated Hospital of Wenzhou Medical University. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Genome-wide DNA methylation analysis was performed using Infinium MethylationEPIC BeadChip on spermatozoal DNA from 20 male patients. Differentially methylated regions (DMRs) were identified and validated using targeted bisulfite amplicon sequencing in spermatozoal DNA from 266 males. RESULT(S) Unsupervised hierarchical clustering analysis revealed three main clusters corresponding to sperm DFI levels (low, medium, or high). Between-cluster comparisons identified 959 (medium-low), 738 (high-medium), and 937 (high-low) DMRs. Sixty-six DMRs were validated in the 266-sample cohort, of which nine CpG fragments corresponding to nine genes (BLCAP, DIRAS3, FAM50B, GNAS, MEST, TSPAN32, PSMA8, SYCP1, and TEX12) exhibited significantly altered methylation in those with high DFI (≥25%) compared with those with low DFI (<25%). CONCLUSION(S) We identified and validated a distinct DNA methylation signature associated with sperm DNA damage in a large, unselected cohort. These results indicate that sperm DNA damage may affect DNA methylation patterns in human sperm.

Abstract
Eukaryotic translation initiation factor 4E (eIF4E) mediates cap-dependent translation. Genetic and inhibitor studies show that eIF4E expression is required for the successful transition from maternal to embryonic control of mouse embryo development. eIF4E was present in the oocyte and in the cytoplasm soon after fertilization and during each stage of early development. Functional knockout (Eif4e−/−) by PiggyBac [Act-RFP] transposition resulted in peri-implantation embryonic lethality because of the failure of normal epiblast formation. Maternal stores of eIF4E supported development up to the two- to four-cell stage, after which new expression occurred from both maternal and paternal inherited alleles. Inhibition of the maternally acquired stores of eIF4E (using the inhibitor 4EGI-1) resulted in a block at the two-cell stage. eIF4E activity was required for new protein synthesis in the two-cell embryo and Eif4e−/− embryos had lower translational activity compared with wild-type embryos. eIF4E-binding protein 1 (4E-BP1) is a hypophosphorylation-dependent negative regulator of eIF4E. mTOR activity was required for 4E-BP1 phosphorylation and inhibiting mTOR retarded embryo development. Thus, this study shows that eIF4E activity is regulated at key embryonic transitions in the mammalian embryo and is essential for the successful transition from maternal to embryonic control of development. Summary: Combined use of a PB [Act-RFP] transgenesis model, selective pharmacological inhibition and expression analyses verified the essential role of eIF4E in the transition from maternal to embryonic control of mouse development.

Abstract
Colorectal cancer (CRC) is a prevalent malignancy with poor prognosis and survival. As a Ca2+ binding protein, S100P plays a role in calcium-dependent signal transduction pathways that involve in diverse biological processes. Our previous studies have shown that S100P is overexpressed in CRC tissues and regulates cell growth, invasion, and metastasis in CRC. Therefore, S100P is expected to be an effective target for CRC therapy. Aptamers are short single-stranded oligonucleotides that could serve as specific and high-affinity probes to a wide range of target molecules for therapeutic purposes. In this study, we generated a novel DNA aptamer against S100P (AptS100P-1) by way of the SELEX process and high-throughput sequencing. The binding assay showed that AptS100P-1 had a high affinity for S100P protein. Further experiments indicated that AptS100P-1 is relatively stable in a cell culture system and could be used in flow cytometry analysis, dot blot assay, and fluorescence microscopy analysis to detect S100P. Moreover, AptS100P-1 was capable of binding to cells and had an inhibitory effect on CRC cell growth in vitro and in vivo. Also, AptS100P-1 inhibited the migration and epithelial-mesenchymal transition of CRC cells expressing S100P. These results indicate a novel DNA aptamer targeting S100P, which might be a potential therapeutic strategy for targeting S100P against S100P-expressing CRC.

Abstract
The pathophysiology of polycystic ovary syndrome (PCOS) is characterized by granulosa cell (GC) dysfunction. m6A modification affects GC function in patients with premature ovarian insufficiency (POI), but the role of m6A modification in PCOS is unknown. The purpose of the prospective comparative study was to analyse the m6A profile of the luteinized GCs from normovulatory women and non‐obese PCOS patients following controlled ovarian hyperstimulation. RNA m6A methylation levels were measured by m6A quantification assay in the luteinized GCs of the controls and PCOS patients. Then, m6A profiles were analysed by methylated RNA immunoprecipitation sequencing (MeRIP‐seq). We reported that the m6A level was increased in the luteinized GCs of PCOS patients. Comparative analysis revealed differences between the m6A profiles from the luteinized GC of the controls and PCOS patients. We identified FOXO3 mRNA with reduced m6A modification in the luteinized GCs of PCOS patients. Selectively knocking down m6A methyltransferases or demethylases altered expression of FOXO3 in the luteinized GCs from the controls, but did not in PCOS patients. These suggested an absence of m6A‐mediated transcription of FOXO3 in the luteinized GCs of PCOS patients. Furthermore, we demonstrated that the involvement of m6A in the stability of the FOXO3 mRNA that is regulated via a putative methylation site in the 3’‐UTR only in the luteinized GCs of the controls. In summary, our findings showed that altered m6A modification was involved in up‐regulated expression of FOXO3 mRNA in the luteinized GCs from non‐obese PCOS patients following controlled ovarian hyperstimulation.

Abstract
OBJECTIVE Perlecan, which is also called heparan sulfate proteoglycan 2 (HSPG2), is a protein encoded by the HSPG2 gene that maps to 1p36.12 in the human genome. In this study, we assessed the independent prognostic value of HSPG2 in terms of overall survival (OS) and recurrence-free survival (RFS) in patients with LGG. PATIENTS AND METHODS A retrospective study was conducted by using data in the Cancer Genome Atlas-Low Grade Glioma (TCGA-LGG). RESULTS Increased HSPG2 expression was an independent prognostic indicator of poor OS in oligoastrocytoma (HR: 1.644, 95% CI: 1.116-2.423, p = 0.012) and in oligodendroglioma (HR: 1.459, 95% CI: 1.138-1.871, p = 0.003). In addition, increased HSPG2 expression independently predicted poor RFS in oligodendroglioma (HR: 1.402, 95% CI: 1.110-1.770, p = 0.005). Furthermore, we observed that high HSPG2 expression was associated with significantly shorter OS and RFS in oligodendroglioma, no matter the patients received radiotherapy or not. Using copy number alterations (CNAs) and DNA methylation data in TCGA-LGG, we found that DNA copy deletion was generally associated with decreased HSPG2 expression. Regression analysis suggested a weak negative correlation between HSPG2 expression and HSPG2 DNA methylation (Pearson's r = -0.388). CONCLUSIONS Increased HSPG2 expression could independently predict poor OS in oligoastrocytoma and oligodendroglioma and also independently predicted poor RFS in oligodendroglioma. Its expression is modulated by both DNA copy number and DNA methylation in oligodendroglioma.

Abstract
Circadian rhythms have been found in some reproductive functions phenotypes but remain unclear for sperm DNA fragmentation index (DFI). The present study aims to investigate the diurnal variation of DFI in mice model and men sperm. Adult male mice were sacrificed for sperm DFI with Sperm Chromatin Structure Assay (SCSA) in 24 hours at 6 evenly distributed time points. A cosinor pattern of DFI was observed with a nadir at zeitgeber time 10 AM. In a community population with 630 semen samples collected between 8 AM and 20 PM, the temporal variation of DFI also fit a cosinor pattern with a - 343° acrophase and a nadir at 11 AM (P = .031). In a reproductive-medical-center dataset of 10752 semen samples collected between 7 AM and 11 AM, the decreasing trend of DFI was also confirmed. For the males with multiple samples, intra-individual comparison between different timepoints was performed, and each consecutive hour after 7 AM was also associated with 2.5 (95% CI: -1.0, 5.9)% lower DFI by SCSA or 4.9 (1.9, 7.8)% lower DFI by SCD. Our study reveals a daily diurnal variance in sperm DFI which may suggest a practical approach to get more qualified sperms for natural or assisted reproduction.

Abstract
Objective: To explore the efficacy of tenofovir disoproxil and adefovir dipivoxil treatment in patients with hepatitis B virus e antigen (HBeAg) negative was analyzed through the comparison of highly sensitive HBV viral load monitoring with HBV genotyping and drug resistance mutations. Methods: The clinical data of newly diagnosed chronic hepatitis B patients from January 2015 to June 2017 in outpatients and inpatients were randomly divided into tenofovir and adefovir group. Quantitative detection of HBV DNA levels before therapy and at 12, 24, 48, 96, and 120 weeks after therapy were determined for HBV genotypes and drug-resistant mutations in HBeAg-negative patients. Student's t-test was used to compare the measurement data between groups. The data of comparison between groups were tested by χ (2). Results: A total of 106 cases of HBeAg-negative patients were collected. Tenofovir disoproxil had a higher rate of HBV DNA suppression (54%) than adefovir dipivoxil treatment (42%), but the difference was not statistically significant (P = 0.19). After 120 weeks of treatment, a total of 46 patients (93.9%) were enrolled in the tenofovir disoproxil group with HBV DNA quantitation < 2 000 IU / ml. Adefovir dipivoxil group of patients with HBV DNA < 2 000 IU / ml a total of 40 cases, accounting for 75.5%. The difference between the two groups was statistically significant (P < 0.05). For 49 cases of HBeAg-negative patients, HBV B, C, B and C were mixed before tenofovir dipivoxil treatment, and C1653T, A1762T and G1764A mutation sites were detected in patients with D genotype. Patients C, B, C, B, and C were examined for C1673T, G1896, G1858, G1899A. After treatment, the detection rate of the above mutation sites decreased, but C1653T, C1673T and G1899A were not detected. New mutation sites such as G1915A / C, L180M, M204V, V207I / L, T184A and V173L were detected, Low resistance rate (25%). Conclusion: Tenofovir disoproxil can be recommended as a treatment for HBeAg-negative patients. For HBeAg-negative patients, the choice of high-sensitivity detection of HBV DNA levels, better monitoring of anti-HBV efficacy.
