Abstract
The present study aimed to elucidate the genetic features of multiple lung cancer (MLC) and identify effective molecular markers for diagnosis using next generation sequencing (NGS). The present data may also inform patient treatment and prognosis. A total of 35 lesions were obtained from 17 patients with MLC. Based on lesion histology and NGS, 13 cases of multiple primary lung cancer (MPLC) were identified and 4 cases were classified as intrapulmonary metastasis (IPM). All 4 patients with IPM exhibited an epidermal growth factor receptor (EGFR) mutation and synchronous mutation of at least one tumor suppressor gene. The frequency and percentage of EGFR mutations, accompanied with tumor suppressor genes, were significantly higher in patients with IPM compared with MPLC. Furthermore, a high EGFR-heterogeneity score and male sex were risk factors of IPM occurrence. There were significant differences in mean EGFR mutation abundance alone, mutations of tumor suppressor genes and mutations of EGFR combined with tumor suppressor genes between patients with adenocarcinoma (ADC) and adenocarcinoma in situ (AIS). In conclusion, histological characteristics combined with genetic alterations may be an effective method for the diagnosis of MPLC and IPM, and NGS may serve as a useful diagnostic tool. MLC exhibited unique molecular characteristics, including higher rates of EGFR mutations, EGFR driver mutations accompanied with tumor suppressor gene mutations and the absence of anaplastic lymphoma kinase mutations, which may help distinguish between patients with MPLC or IPM. The present study hypothesized that the mean frequency of EGFR mutations, mutations of tumor suppressor genes and mutations of both EGFR and tumor suppressor genes may serve an important role in the development of AIS to ADC. The results of the present study highlight the potential underlying mechanisms of lung ADC development, which may assist with future elucidation of effective treatments to prevent the progression of lung cancer.

Abstract
UNLABELLED Using national insurance claims of Taiwan, we found that magnesium oxide (MgO) use is associated with an increased risk of hip fracture in the elderly. Further studies are warranted to explore the mechanisms associated with MgO use that lead to hip fracture. PURPOSE The purpose of this study was to investigate the association between MgO use and hip fracture risk in the elderly (age > 65 years). METHODS This nationwide population-based retrospective study was conducted from 1996 to 2013. Individuals with (n = 26,069) and without (n = 26,069) MgO use were enrolled after propensity score matching. Primary outcome was a hip fracture. After adjusting for age, sex, comorbidities, and medications, multivariate Cox proportional hazards regression models were used to calculate incidences and risk of hip fracture [hazard ratio (HR)]. RESULTS During the mean follow-up duration of 4.8 years in the MgO cohort and 5.7 years in the non-MgO cohort, respectively 1547 and 1107 cases developed a hip fracture. MgO use was identified as a risk factor for hip fracture in both univariate [crude HR, 1.68; 95% confidence interval (CI), 1.55-1.81; p < 0.001] and multivariate [adjusted HR (aHR), 1.66; 95% CI, 1.54-1.80; p < 0.001] Cox proportional hazards regression models. The cumulative incidence of hip fracture was significantly higher in the MgO cohort than in the non-MgO cohort (1.23 per 100 person-years vs. 0.74 per 100 person-years, logrank test, p < 0.001). CONCLUSION MgO use is an independent risk factor for hip fracture in the elderly.

Abstract
Background To investigate the short‐ and medium‐term outcomes of using a reduced‐port laparoscopic surgery (RPLS), compared to multi‐port laparoscopic surgery (MPLS), for the treatment of upper rectal cancer (URC) among elderly patients. Methods We conducted a retrospective analysis of the clinical and follow‐up data of 181 elderly patients with URC, who underwent radical laparoscopic surgery at our hospital, between January 2015 and January 2019. Among these 181 cases, 62 underwent RPLS and 119 MPLS. Results Compared to MPLS, RPLS decreased the length of surgical incision, lower pain on postoperative days 1 and 2, decreased the time to first flatus after surgery, as well as the time to mobilization after surgery. There was no difference between the short‐term outcomes between the two laparoscopic approaches, and no difference in the 3‐year disease‐free and overall survival rate. Conclusion Compared to MPLS, RPLS provides several advantages for the treatment of URC among elderly individuals, including a shorter length of surgical incision, reduced postoperative pain, shorter time to first flatus after surgery, earlier mobilization, and better cosmetic outcomes. These advantages are achieved with no difference in the length of surgery, nor in the 3‐year disease‐free and overall survival rate, compared to MPLS.

Abstract
Triple-negative breast cancer (TNBC) has a poorer prognosis than other subtypes of breast cancer; however, it lacks effective targeted therapies clinically. In this study, we found FZU-0038-056, a novel compound derived from last-stage functionalization of tetrahydro-β-carboline scaffold, showed the most potent anti-cancer activity against TNBC cells among the 42 synthesized derivatives. We found FZU-0038-056 significantly induces apoptosis in HCC1806 and HCC1937 TNBC cells. FZU-0038-056 reduces the expression levels of several anti-apoptosis proteins, including Bcl-2, Mcl-1 and XIAP. Furthermore, we found FZU-0038-056 induces apoptosis partially through inhibiting the expression of Bcl-2. Finally, we found FZU-0038-056 significantly suppresses HCC1806 xenograft tumor growth in nude mice without affecting their body weight. Therefore, FZU-0038-056 has the potential to be a new anticancer agent for treating human TNBC.

Abstract
Background Alzheimer’s disease (AD) is a neurodegenerative disorder strongly correlated with a dysfunctional immune system. Our previous results demonstrated that inactivated influenza vaccine (IIV) facilitates hippocampal neurogenesis and blocks lipopolysaccharide (LPS)-induced cognitive impairment. However, whether IIV improves cognitive deficits in an AD mouse model remains unclear. In addition, early interventions in AD have been encouraged in recent years. Here, we investigated whether IIV immunization at the preclinical stage of AD alters the brain pathology and cognitive deficits in an APP/ PS1 mouse model. Methods We assessed spatial learning and memory using Morris water maze (MWM). The brain β-amyloid (Aβ) plaque burden and activated microglia were investigated by immunohistochemistry. Furthermore, flow cytometry was utilized to analyze the proportions of Treg cells in the spleen. A cytokine antibody array was performed to measure the alteration of cytokines in the brain and peripheral immune system. Results Five IIV immunizations activated microglia, reduced the Aβ burden and improved the cognitive impairment. Simultaneously, the IIV-induced immune response broke peripheral immunosuppression by reducing Foxp3+ regulatory T cell (Treg) activities, whereas the restoration of Treg level in the periphery using all-trans retinoic acid (ATRA) blunted the protective effects of IIV on Aβ burden and cognitive functions. Interestingly, IIV immunization might increase proinflammatory and anti-inflammatory cytokine expression in the brain of APP/PS1 mice, enhanced microglial activation, and enhanced the clustering and phagocytosis of Aβ, thereby creating new homeostasis in the disordered immune microenvironment. Conclusions Altogether, our results suggest that early multiple IIV immunizations exert a beneficial immunomodulatory effect in APP/PS1 mice by breaking Treg-mediated systemic immune tolerance, maintaining the activation of microglia and removing of Aβ plaques, eventually improving cognitive deficits.

Abstract
Thymic degeneration and regeneration are regulated by estrogen and androgen. Recent studies have found that long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) are involved in organ development. In this study, RNA sequencing (RNA-seq) results showed that ovariectomy significantly affected 333 lncRNAs, 51 miRNAs, and 144 mRNAs levels (p < 0.05 and |log2fold change| > 1), and orchiectomy significantly affected 165 lncRNAs, 165 miRNAs, and 208 mRNA levels in the thymus. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that differentially expressed genes (DEGs) were closely related to cell development and immunity. Next, we constructed two lncRNA–miRNA–mRNA networks using Cytoscape based on the targeting relationship between differentially expressed miRNAs (DEMs) and DEGs and differentially expressed lncRNAs (DELs) analyzed by TargetScan and miRanda. Besides, we screened DEGs that were significantly enriched in GO and in ceRNA networks to verify their expression in thymocytes and thymic epithelial cells (TECs). In addition, we analyzed the promoter sequences of DEGs, and identified 25 causal transcription factors. Finally, we constructed transcription factor-miRNA-joint target gene networks. In conclusion, this study reveals the effects of estrogen and androgen on the expression of miRNAs, lncRNAs, and mRNAs in mice thymus, providing new insights into the regulation of thymic development by gonadal hormones and non-coding RNAs.

Abstract
BACKGROUND The evolution of male pregnancy is the most distinctive characteristic of syngnathids, and they were recognized as flagship species for marine conservation. Genus Halicampus is an important branch of syngnathid fishes that has not received the attention it deserves. OBJECTIVE To sequence the mitochondrial genome of Halicampus grayi, and investage the genetic structure of its populations. METHODS Degenerate primers were designed to amplify the entire mitochondrial genome of H. grayi. The phylogenetic relationship between H. grayi and other syngnathids were conducted using maximum-likelihood method. Population genetic structure of three geographic population of H. grayi were determined using median-joining haplotype network based on COI and Cytb sequences. RESULTS The complete mitochondrial genome of Halicampus grayi was assembled into a 17,059 bp circular sequence, which contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 D-loop region. The overall base composition of H. grayi is 29.93% A, 29.31% T, 16.23% G and 24.54% C, with a slight A + T rich feature (59.24%). Phylogenetic analysis indicated that H. grayi has a close relationship with Trachyrhamphus serratus. Population genetic analysis revealed a relatively high genetic diversity across different geographic populations of H. grayi, and the results of median-joining haplotype network indicated a lack of structure in populations of H. grayi. CONCLUSION The mitogenome of H. grayi will provided important information about the origin and evolution issues of syngnathid fishes, and the high-level genetic diversity detected in their populations will provide insight into the gene flow pattern of marine fishes.

Abstract
Metformin, an anti-hyperglycemia drug, protected endothelial cells (ECs) from dysfunction while high glucose (HG) caused endothelial dysfunction. Previously, we found that metformin suppressed endothelial-to-mesenchymal transition (EndoMT), a cellular process that promoted endothelial dysfunction. However, the involved mechanism is still unclear. In this study, we found that metformin increased the expression of krüppel-like factor 4 (KLF4) and cholesterol-25-hydroxylase (Ch25h) while HG decreased the expression of KLF4 and Ch25h. In addition, HG promoted EndoMT indicting by the decrease of endothelial maker genes and increase of mesenchymal maker genes. Furthermore, RNA sequence (RNA-seq) data showed that KLF4 suppressed EndoMT. Moreover, we proved that metformin increased Ch25h expression through not only KLF4 but also epigenetic modification including DNA methylation and active histone modification. Lastly, we proved that Ch25h/25 hydroxycholesterol (25 HC)/Liver X receptor α (LXRα) suppressed EndoMT. Altogether, our study demonstrated that KLF4/Ch25h/axis activated by metformin suppressed EndoMT. Therefore, KLF4/Ch25h/axis may be a new potential therapeutic target for endothelial dysfunction diseases.

Abstract
Objective: The authors aim to provide genetic counselling and prenatal gene diagnosis to the families with osteogenesis imperfecta(OI), based on the identification of pathogenetic mutations in large cohort genetic testing. Methods: DNA was extracted from the peripheral blood of parents of the fetuses, and from the villi tissue, amniotic fluid or cord blood of the fetuses using a standard sodium dodecyl sulfate-proteinase K-phenol/chloroform extraction method. PCR combined with Sanger DNA sequencing was performed to validate the pathogenic mutations of 200 fetuses at risk of OI and their parents from 158 families. Allelic analysis of microsatellite markers was applied to exclude the false positive caused by maternal DNA contamination, when both the fetus and the mother harbored the same pathogenic genotype. Results: A total of 83 affected fetuses (83/200, 41.5%) and 12 (12/200, 6.0%) recessive carriers were identified among the 200 fetuses. The 83 affected fetuses included 78 heterozygotes (45 of COL1A1, 32 of COL1A2, one of IFITM5), and 5 compound heterozygotes or homozygotes of recessive OI (two of FKBP10, one of SEC24D, one of WNT1 and one of CRTAP); The 12 recessive carriers included 7 of WNT1, 4 of SERPINF1 and one of SERPINH1. Maternal DNA contamination was excluded from the genomic DNA samples of OI fetuses when their mother with the same affected genotypes. Conclusion: In this study, the authors used an optimized gene diagnosis system of OI to perform prenatal genetic diagnosis to 200 fetuses at high risk of OI, and provided precisely genetic counselling to the OI families.

Abstract
Objective: To explore the relationship between hemoglobin (Hb) level during the first trimester of pregnancy and gestational diabetes mellitus (GDM). Methods: A total of 1 276 participants, who underwent scheduled prenatal examination and normal singleton delivery at the Fifth People's Hospital of Shanghai and Hospital of Intergrated Chinese and Western Medicine in Minhang District, from January 2016 to May 2018 were included. There were 99 cases of GDM (GDM group) and 1 177 cases of normal (control group) pregnant women.Based on the serum Hb level during the first trimester of pregnancy, participants were divided into three groups, 236 cases of low Hb level group (Hb<110 g/L), 868 cases of normal Hb level group (110 g/L≤Hb<130 g/L), and 172 cases of high Hb level group (Hb≥130 g/L). Maternal clinical data were collected, including Hb level during the first trimester of pregnancy, three-point blood glucose (BG) of oral glucose tolerance test (OGTT) and fasting insulin during the second trimester of pregnancy. Homeostasis model assessment of insulin resistance index (HOMA-IR) and homeostasis model assessment of pancreatic β cell function index (HOMA-β) were used to evaluate insulin resistance and pancreatic β cell function. Results: (1) Hb level during the first trimester of pregnancy in GDM group was significantly higher than that in control group [(123±10),(119±11) g/L, P<0.05]. There were no significant difference in gravidity, parity, index of liver and renal function (all P>0.05). (2) Pre-pregnancy body mass index (BMI), 1-hour BG and 2-hour BG of OGTT were significantly increased in the high Hb level group during the first trimester of pregnancy, which were (23±4) kg/m(2), (7.3±2.0) mmol/L, and (6.5±1.4) mmol/L (P<0.05), respectively. The pre-pregnancy BMI, 1-hour BG and 2-hour BG of the normal or low Hb level group were (22±3) kg/m(2), (6.7±1.6) mmol/L, (6.1±1.2) mmol/L; (22±3) kg/m(2), (6.5±1.5) mmol/L, (5.9±1.1) mmol/L, respectively. There were no statistically significant difference in levels of fasting blood glucose, fasting insulin, HOMA-IR and HOMA-β within 3 groups (all P>0.05). (3) In the high Hb level group, prevalence of pregnancy overweight or obesity and GDM were the highest, which were 37.2%(64/172) and 15.1%(26/172), respectively; the differences were statistically significant (all P<0.05). (4) The serum Hb level in the first trimester was positively related with pre-pregnancy BMI (r=0.130, P<0.05), 1-hour BG (r=0.129, P<0.05), 2-hour BG (r=0.134, P<0.05), fasting insulin (r=0.096, P<0.05), and HOMA-IR (r=0.101, P<0.05).Logistic regression indicated that Hb≥130 g/L during the first trimester of pregnancy was an independent risk factor for GDM (OR=2.799, 95%CI: 1.186-6.604; P<0.05). Conclusion: The high level of Hb (Hb≥130 g/L) during the first trimester of pregnancy is associated with GDM.

Abstract
The Krüppel-like factor 5 (KLF5) transcription factor is highly expressed in basal type breast cancer and promotes breast cancer cell proliferation, survival, migration, and tumorigenesis. KLF5 protein stability is regulated by ubiquitination. In this study, ubiquitin-specific protease 3 (USP3) was identified as a new KLF5 deubiquitinase by genome-wide siRNA library screening. We demonstrated that USP3 interacts with KLF5 and stabilizes KLF5 via deubiquitination. USP3 knockdown inhibits breast cancer cell proliferation in vitro and tumorigenesis in vivo, which can be partially rescued by ectopic expression of KLF5. Furthermore, we observed a positive correlation between USP3 and KLF5 protein expression levels in human breast cancer samples. These findings suggest that USP3 is a new KLF5 deubiquitinase and that USP3 may represent a potential therapeutic target for breast cancer.

Abstract
Surgical margin principle is one of the central surgical principles for head and neck cancers. Negative surgical margin is the primary purpose of surgery for head and neck cancers. This paper is based on the current clinical application of surgical margins of head and neck cancers, and it is proposed that surgical margins of head and neck cancers may be classified into three types: surface margin, deep margin, and tissue interface margin in consideration of surgical exposure of tumors. The classification of surgical margins can make the clinical application and the research of surgical margins of head and neck cancers more systematic and clear.

Abstract
Background Secretory breast carcinoma is an exceptionally rare type of breast carcinoma. Only 5 cases of pure secretory carcinoma in situ have been reported in English literature. Herein, we reported a rare case of pure secretory breast carcinoma in situ. Case presentation The patient is a 38-year-old female with bloody discharge from the left nipple. Microscopically, the terminal-duct lobular units were enlarged and filled with tumor cells. The tumor cells were arranged in cystic, microcystic, solid and papillary pattern and formed a honeycomb-like appearance. The presence of intracellular and extracellular eosinphilic PAS-positive material was the most remarkable feature. Immunohistochemically, myoepithelial markers highlighted the complete presence of myoepithelial cells around the tumour nests. Tumour cells were strongly positive for S-100 and CK5/6, negative for ER, PR and HER2. Fluorescence in situ hybridization analysis showed ETV6-NTRK3 fusion. Conclusion Secretory carcinoma in situ shares the same morphological, immunohistochemical and molecular features with invasive secretory carcinoma except that the papillary growth pattern is more common in the introductal components. Cautions should be taken to distinguish secretory carcinoma in situ from other introductal lesions. Our report is an important supplement to the morphology spectrum of secretory breast carcinoma.

Abstract
Objective: To analyze the clinical characteristics of hepatic flare and evaluate efficacy of antiviral treatment in pregnant women with chronic HBV infection. Methods: A single-center, open-label, prospective study was conducted, and pregnant women with chronic HBV infection were enrolled. Liver function, HBV serum markers and HBV DNA of pregnant women with chronic HBV infection were reviewed during every 4 to 12 weeks of gestation period. The proportion and clinical characteristics of hepatitis flare during pregnancy were observed. Logistic regression analysis was used to predict hepatic flare in pregnant women with chronic HBV infection. Antiviral therapy with telbivudine (LdT) or tenofovir dipivoxil (TDF) was used to treat hepatic flare during pregnancy. Sequential entecavir (ETV) or TDF was applied after the delivery. Treatment course and drug withdrawal in pregnant women with hepatic flare was the same as those of the general patients with chronic hepatitis B. Liver function, HBV serum markers and HBV DNA were measured in pregnant women with hepatic flare at different time points (4, 12, 24 and 52 weeks). A t-test was used to compare the hepatic flare in pregnant women with and without hepatitis group. HBsAg and HBeAg were used to quantify the receiver operating characteristic (ROC) curve of pregnant women with hepatic flare during pregnancy. Area under the ROC curve was used to calculate the optimal cut-off value corresponding to the maximum sensitivity and specificity of the ROC curve. Results: Of the 220 pregnant women with chronic HBV infection, 55 (25%) had hepatitis flare during pregnancy and received antiviral treatment. Among the 55 women with hepatic flare during gestation, 47 (85.46%) had hepatic flare in the mid-second trimester (12-24 weeks); average peak value of alanine aminotransferase (ALT) was 220.62 U/L, and the average peak value of ALT in 32 cases (58.18%) of pregnant women with hepatic flare was between 2-5 × ULN. HBsAg and HBeAg quantification were significantly lower in pregnant women with hepatic flare during pregnancy than with non-hepatitis (t = -3.745, P < 0.001; t = -2.186, P = 0.030). Multivariate logistic regression analysis showed that pregnant women with HBeAg < 3.065 log10 s/co were 7.576 times more likely to have hepatic flare during pregnancy (95% confidence interval: 3.779-15.190). ALT normalization, undetectable HBV DNA levels, HBeAg loss and HBeAg seroconversion in 55 pregnant women with hepatic flare at 52-week treatment was 100% (55/55), 74.55% (41/55), 47.27% (26/55) and 41.82% (23/55), respectively. HBsAg quantification at 52 weeks was significantly lower than baseline HBsAg quantification (3.32 + 0.37) log(10) IU/ml and (3.95 + 0.40) log(10) IU/ml; t = 8.465, P < 0.001). Conclusion: Hepatic flare often occurs in the second trimester of pregnancy in pregnant women with chronic HBV infection and baseline HBeAg quantification is an independent predictor of hepatic flare. HBeAg seroconversion rate increased at 52 weeks after antiviral therapy.

Abstract
We investigated the relationship between teachers' emotional intelligence (EI) and self-efficacy, and tested whether this relationship was mediated by teaching performance. Participants were 467 Chinese middle school teachers (312 women; 66.8%). They completed 3 questionnaires relating
to EI, self-efficacy, and teaching performance. The results showed that the total effect of EI on self-efficacy was .61, indicating that higher EI is positively correlated with a higher level of self-efficacy. This relationship was partially mediated by teaching performance. In the mediating
model for teaching performance, the direct effect of EI on teachers' self-efficacy was .23 and the mediating effect of teaching performance on the relationship between EI and teachers' self-efficacy was .45. In addition, both the direct and mediating effects were invariant across gender and
teaching experience. These results indicate that an increase in EI largely enhances teachers' self-efficacy only when emotional skills are successfully used to improve teachers' performance.

Abstract
Background Human melanoma is a malignant tumor originated from melanocytes with high invasion, metastasis, and poor prognosis. In this study, the effects of naphthalimides UNBS5162 and amonafide on the properties of proliferation and apoptosis in human melanoma cells were confirmed. Methods Cell proliferation was determined by CCK8 and clone formation assay. Transwell assay was performed to detect the migration and invasion of M14 and A375 cells. Cell apoptosis was estimated using flow cytometry. Results In a drug sensitivity assay, cell viability decreased with increasing concentrations of UNBS5162 or amonafide. Likewise, proliferation of M14 or A375 cells treated with 10 μM UNBS5162 or 8 μM amonafide decreased significantly when compared with negative control (NC) cells, their inhibition effect verified by means of a clone formation assay. After the treatment with UNBS5162 or amonafide, the migration of melanoma cells was inhibited in a dosede-pendent manner. The number of invaded cells treated with UNBS5162 was also significantly reduced when compared with those of the NC cells. The apoptotic cell numbers treated with UNBS5162 or amonafide decreased significantly when compared with the M14 and A375 cells in the NC group. According to Western blot results, phosphorylation of AKT and expressions of mesenchymal marker factors were inhibited in cells treated with UNBS5162 or amonafide. Conclusion These results reveal that UNBS5162 inhibits the cell activity of melanoma cells through the AKT/mTOR signaling pathway, and reverses epithelial–mesenchymal transition conversion in human melanoma cells. This study on UNBS5162 and amonafide in melanomas provides an experimental basis of their uses and potential value on human melanoma treatment.

Abstract
Objective: To investigate whether HBV genotype influences HBV DNA and RNA responses to tenofovir(TDF) and telbivudine(LDT) in pregnant women with HBeAg-positive in Guizhou. Methods: This was a retrospective analysis of 75 pregnant women hepatitis B with HBsAg and HBeAg double-positive(19-38 years old, median age 26 years old), who were enrolled in the Department of Infectious Diseases and Obstetrics Clinic of the Affiliated Hospital of Guizhou Medical University from May 2016 to July 2017.Blood samples were collected at 12-24, 28-32 and 36-40 weeks of pregnancy for analyses of genotype, including hepatitis B surface antigen(HBsAg), hepatitis B e antigen (HBeAg), HBV DNA, HBV RNA and liver function, alanine transaminase(ALT), aspartate transaminase(AST), total bilirubin(TBiL), total bile acids(TBA), cholinesterase(CHE), alkaline phosphatase (ALP). Continuous variable was adopted by means of mean±standard deviation, and categorical variables were used for statistical analysis. Results: The HBV genotype was B in 64.0%(48/75)and C in 36.0%(27/75). The TDF and LDT groups showed no differences in demographic and clinical characteristics, including liver function tests, HBsAg, HBeAg, log(10)HBV DNA and log(10)HBV RNA.TDF groups, pre-treatment: HBV DNA (4.8±2.0), HBV RNA (6.4±1.1); at 4 weeks of treatment: HBV DNA (4.0±0.8), HBV RNA (6.0±0.9); at the end of treatment: HBV DNA (3.1±0.7), HBV RNA (5.5±0.8). LDT groups, pre-treatment HBV DNA (5.1±2.0), HBV RNA(6.5±0.9); at 4 weeks of treatment: HBV DNA (4.4±1.2), HBV RNA(6.5±0.8); at the end of treatment: HBV DNA(3.5±1.2), HBV RNA (6.1±0.7). Compared with pre-treatment (12-24 weeks), the TDF and LDT group showed significant reductions in log(10)(HBV DNA) and log(10)(HBV RNA) at 36-40 weeks ( P<0.05). Under the influence of excluding other variables, the genotype had a certain influence on the HBV RNA load.That was, HBV RNA in patients with the C genome decreased by 0.54 units(log(10)) at the end of the treatment compared to patients with the B genome, and the P value was less than 0.05. Conclusion: B and C genotypes are predominant in pregnant women with hepatitis B in Guizhou Province. B-type viruses are more easily controlled when different genotypes are treated with nucleotide analogues.
