BACKGROUND: Preoperative prediction of microvascular invasion (MVI) is critical for treatment strategy making in patients with hepatocellular carcinoma (HCC). We aimed to develop a deep learning (DL) model based on preoperative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to predict the MVI status and clinical outcomes in patients with HCC. METHODS: We retrospectively included a total of 321 HCC patients with pathologically confirmed MVI status. Preoperative DCE-MRI of these patients were collected, annotated, and further analyzed by DL in this study. A predictive model for MVI integrating DL-predicted MVI status (DL-MVI) and clinical parameters was constructed with multivariate logistic regression. RESULTS: Of 321 HCC patients, 136 patients were pathologically MVI absent and 185 patients were MVI present. Recurrence-free survival (RFS) and overall survival (OS) were significantly different between the DL-predicted MVI-absent and MVI-present. Among all clinical variables, only DL-predicted MVI status and a-fetoprotein (AFP) were independently associated with MVI: DL-MVI (odds ratio [OR] = 35.738; 95% confidence interval [CI] 14.027-91.056; p < 0.001), AFP (OR = 4.634, 95% CI 2.576-8.336; p < 0.001). To predict the presence of MVI, DL-MVI combined with AFP achieved an area under the curve (AUC) of 0.824. CONCLUSIONS: Our predictive model combining DL-MVI and AFP achieved good performance for predicting MVI and clinical outcomes in patients with HCC.

OBJECTIVE: To systematically evaluate the efficacy of Shengmai San in patients with cardiotoxicity of anthracyclines. METHODS: Randomized controlled trials (RCTs) were identified by searching China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Biomedical Literature Database (CBM), PubMed, Cochrane Library, and Embase Databases from the inceptions until December 2020. The Cochrane Handbook was used to evaluate the risk of bias in the included studies. Data analysis was conducted using RevMan 5.3 software. RESULTS: Totally 19 RCTs with 2,331 participants were included in this review. Results showed that in improving arrhythmia (13 RCTs, n=1,877, RR=0.37, 95%CI 0.25 to 0.52, P<0.00001), the treatment group was superior to the control group. In terms of reducing left ventricular end-diastolic diameter (LVEDD, 2 RCTs, n=128, MD=-0.79, 95%CI -0.93 to -0.65, P<0.00001) and left ventricular end systolic diameter (LVESD, 2 RCTs, n=128, MD=-0.58, 95%CI -0.82 to -0.35, P<0.00001), the treatment group was also better than the control group. In reducing myocardial enzymes such as creatine kinase (CK) [(3 RCTs, n=256, SMD=-0.80, 95%CI -1.16 to -0.44, P<0.0001), (2 RCTs, n=126, SMD=-0.62, 95%CI -0.98 to -0.26, P=0.0007)], the treatment group was superior to the control group. CONCLUSION: Shengmai San has a positive effect on the treatment of cardiotoxicity from anthracyclines. However, in the future, it is still necessary to conduct high-quality RCTs to verify its efficacy.

Hypertension is the most prevalent chronic disease and a risk factor for various diseases. Although its mechanisms and therapies are constantly being updated and developed, they are still not fully clarified. In recent years, novel gut microbiota and its metabolites have attracted widespread attention. It is strongly linked with physiological and pathological systems, especially TMA and TMAO. TMA is formed by intestinal microbial metabolism of choline and L-carnitine and converted into TMAO by FMO3. This paper collected and collated the latest researches and mainly discussed the following four parts. It introduced gut microbiota; provided a focus on TMA, TMA-producing bacteria, and TMAO; summarized the alternations in hypertensive patients and animals; discussed the mechanisms of TMAO with two respects; and summarized the regulatory factors may be as new interventions and therapies of hypertension. And, more relevant studies are still prospected to be accomplished between hypertension and TMA/TMAO for further clinical services.

BACKGROUND: We demonstrated that drinking hydrogen-rich water (HRW) inhibits endometrial tumor growth in our previous work. This research is to identify differentially expressed proteins (DEPs) between HRW and purified water groups in a xenograft mouse model of endometrial cancer (EC). METHODS: Samples were analyzed using tandem mass tags (TMTs) coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS). DEPs were identified using bioinformatics to determine potential molecular functions and immunohistochemical (IHC) staining. RESULTS: In total, 11 DEPs were identified in the HRW group relative to the control. The up-regulated proteins included Gatad1, Ttyh3, Nek4, Dyrk2, and Gimap1, while the down-regulated proteins included SP1, Msl1, Plekha7, Dtwd2, MSRA, and KRAS. Gene Ontology (GO) annotations and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were associated with the binding region, biological regulation, endocrine resistance, estrogen signaling, choline metabolism in cancer and human cytomegalovirus infection. Furthermore, network analysis indicated that KRAS and MSRA interact with YWHAE. KRAS, YWHAE and SP1 were strongly expressed, while MSRA was weak expressed in atypical hyperplasia and EC tissue as well as in HRW group in xenograft tumor tissue. CONCLUSIONS: KRAS, YWHAE, SP1 and MSRA might be regarded as focused biomarkers to assess the prognosis of EC.

RESUMEN
PURPOSE: To compare the detection rate of HBV antigens in different samples, and to explore the significance of saliva transmission in the spread of HBV. METHODS: Eight hundred and ninety-one ordinary saliva samples, 578 bloody saliva samples and 450 serum samples of dental patients were collected from Shanghai Sixth People's Hospital and Dahua Hospital, and HBsAg, HBsAb, HBeAg, HBeAb and HBcAb were detected by ELISA method. SPSS19.0 software package was used for chi-square test. RESULTS: There was no significant difference in gender, age and household registration between three types of saliva sample: ordinary saliva, bloody saliva and serum (P>0.05). Eight, 11 and 12 of HBV-M combination modes were detected from the above three samples. Six "HHAs" were detected from the normal saliva samples (0.67%), and the detection rate was similar to bloody saliva samples (0.87%) and serum samples (1.56%) (P>0.05). HBsAg detection rate in serum samples was significantly higher than bloody saliva and ordinary saliva (P<0.001). The difference between ordinary saliva and bloody saliva and between different age-group, sex-group, and census register group in serum samples was of no significant difference (P>0.05), and so was HBeAg. CONCLUSIONS: Saliva is an important transmission route of hepatitis B, and should be taken seriously. When the infectivity is strong, the virus content in saliva is high. Hepatitis B virus in saliva may come from other than sources except blood.

BACKGROUND: Congenital cataract (CC) is the leading cause of visual impairment or blindness in children worldwide. Because of highly genetic and clinical heterogeneity, a molecular diagnosis of the lens disease remains a challenge. METHODS: In this study, we tested a three-generation Chinese family with autosomal dominant CCs by targeted sequencing of 45 CC genes on next generation sequencing and evaluated the pathogenicity of the detected mutation by protein structure, pedigree validation, and molecular dynamics (MD) simulation. RESULTS: A novel 15 bp deletion on GJA8 (c.426_440delGCTGGAGGGGACCCT or p. 143_147delLEGTL) was detected in the family. The deletion, concerned with an in-frame deletion of 5 amino acid residues in a highly evolutionarily conserved region within the cytoplasmic loop domain of the gap junction channel protein connexin 50 (Cx50), was in full cosegregation with the cataract phenotypes in the family but not found in 1100 control exomes. MD simulation revealed that the introduction of the deletion destabilized the Cx50 gap junction channel, indicating the deletion as a dominant-negative mutation. CONCLUSIONS: The above results support the pathogenic role of the 15 bp deletion on GJA8 in the Chinese family and demonstrate targeted genes sequencing as a resolution to molecular diagnosis of CCs.

A pot experiment including five treatments, i.e., CK (neither fertilizer nor super absorbent polymers), U (urea alone), S [super absorbent polymers (SAP) alone], SUM (SAP mixed with urea) and SUG (gel made of SAP and urea) was conducted to evaluate their effects on fine root morphological characteristics, fine root absorption area, fine root nitrogen metabolism and nitrogen use efficiency of Platycladus orientalis bareroot seedlings. Results showed that compared with U treatment, the SUG treatment significantly increased the biomass, length, specific root length, surface area and volume of fine root. The total absorption area and active absorption area of fine root were also increased remarkably under the SUG treatment. The specific root length in the SUG treatment was increased by 34.7%, 37.9%, 41.1% and 12.4% compared with the treatments of CK, U, S and SUM, respectively. Compared with the U treatment, the activities of nitrate reductase, glutamine synthase, glutamate synthase and glutamate dehydrogenase in fine root of the SUG treatment was improved by 41.2%, 76.6%, 30.7% and 125.8%, respectively, while the ratio of GS to GDH decreased. Not only the ground diameter and plant height, but also the dry matter accumulation of aboveground and underground parts was remarkably enhanced under the SUG treatment. The nitrogen use efficiency was 40.7% in the SUG treatment, being 118.8% and 44.5% higher than the U and SUM treatments, respectively. Gel made of SAP and urea was able to significantly increase the nitrogen use efficiency, promote the growth and enhance the ability of drought resistance by improving the morphological characteristics, enhancing the absorption area and key enzymes activities of nitrogen metabolism in the fine root of P. orientalis bareroot seedlings.

OBJECTIVE: This research was carried out to investigate the effectiveness, rationality, and safety of laparotomy management compared with uterine artery embolization (UAE) combined with methotrexate (MTX) for the treatment of deep implantation cesarean scar pregnancy (CSP II). MATERIALS AND METHODS: Data from 29 patients seen between June 2008 and February 2012 were retrospectively analyzed. The patients were divided into the surgery group and the UAE combined with MTX group according to the treatment they received. We compared the clinical characteristics and treatment outcomes between the two groups. RESULTS: The patients' clinical characteristics did not differ between the surgery group and the UAE combined with MTX group. However, the mean blood loss was decreased in the surgery group compared with the UAE combined with MTX group (90 ± 4.5 mL vs. 286 ± 5.2 mL, p < 0.05). No patients required blood transfusion in the surgery group, whereas two patients in the UAE combined with MTX group received blood transfusions. The length of time for the serum beta human chorionic gonadotropin (ß-HCG) level to normalize, the time required for the disappearance of the gestational mass, and the duration of hospital stay were significantly less in the surgery group than in the UAE combined with MTX group (13.7 ± 1.0 days vs. 40.7 ± 1.7 days, 7.1 ± 1.3 days vs. 135.4 ± 6.7 days, and 11.0 ± 1.2 days vs. 41.4 ± 3.2 days, respectively; p < 0.01). Although the treatment success rate did not differ significantly between the two groups, the success rate was 100% for the surgery group and 73% for the UAE combined with MTX group. CONCLUSION: Surgical treatment can remove gestational masses and allow wound repair. Moreover, laparotomy is available in almost all hospitals. Thus, surgery can be an effective and reasonable treatment for CSP II.

OBJECTIVE: To determine the optimum treatment for viral myocarditis (VMC). METHODS: A total of 126 VMC patients were randomly divided into the control group (42 cases) that was treated with conventional Western medicine, and the intervention group (84 cases) that was treated with a combination of Chinese medicine (CM) and Western medicine intervention termed optimum proposal of integration of disease and syndrome (OPIDS). Before and after 4 weeks of treatment, the integral of CM syndrome, self-rating depression and anxiety scales (SDS and SAS, respectively), echocardiograms (ECGs), heart rate variability and left ventricular systolic function were observed. RESULTS: Compared with the control group, the intervention group showed significant reductions on the SDS and SAS (P <0.05); improvement of premature ventricular beats, atrioventricular blocks, ST-segment abnormalities, and significant T wave changes (P <0.05); greater reductions in standard deviation of NN intervals (SDNN), standard deviation for per 5 min averages NN intervals (SDANN), and root-mean-square of successive difference of NN intervals (rMSSD) (P <0.05); and increases in cardiac output, stroke volume, and ejection fraction, the last of which was statistically significant (P <0.05). Overall, the treatment efficacy rate was significantly better P<0.05) in the intervention group (75.61%) compared with the control group (69.70%). CONCLUSION: OPIDS is quite effective in treating VMC and improves symptoms such as anxiety and depression, left ventricular systolic dysfunction, premature ventricular contraction, and cardiac autonomic nervous system dysfunction.

BACKGROUND: Generation of large mate-pair libraries is necessary for de novo genome assembly but the procedure is complex and time-consuming. Furthermore, in some complex genomes, it is hard to increase the N50 length even with large mate-pair libraries, which leads to low transcript coverage. Thus, it is necessary to develop other simple scaffolding approaches, to at least solve the elongation of transcribed fragments. RESULTS: We describe L_RNA_scaffolder, a novel genome scaffolding method that uses long transcriptome reads to order, orient and combine genomic fragments into larger sequences. To demonstrate the accuracy of the method, the zebrafish genome was scaffolded. With expanded human transcriptome data, the N50 of human genome was doubled and L_RNA_scaffolder out-performed most scaffolding results by existing scaffolders which employ mate-pair libraries. In these two examples, the transcript coverage was almost complete, especially for long transcripts. We applied L_RNA_scaffolder to the highly polymorphic pearl oyster draft genome and the gene model length significantly increased. CONCLUSIONS: The simplicity and high-throughput of RNA-seq data makes this approach suitable for genome scaffolding. L_RNA_scaffolder is available at http://www.fishbrowser.org/software/L_RNA_scaffolder.

Achilles tendon rupture is a common injury, and its complications can impair function. Numerous operations have been described for reconstructing the ruptured tendon, but these methods can compromise the microcirculation in the tendon and can seriously damage healing of the tendon. Suturing with a minimally invasive tenocutaneous technique soon after the rupture and systematic functional exercise can greatly reduce the possibility of complications. From June 1996 to February 2007, we treated 20 patients (14 males), who ranged in age from 21 to 66 years old, with this method. After follow-up period of 1 to 7 years, the mean American Orthopedic Foot and Ankle Society Ankle Hindfoot score was 95 (range 90 to 98), and the maximum length of postoperative scarring was 3 cm. One patient again ruptured his Achilles tendon 1 year after surgery in an accident; however, after 10 months, the repaired tendon was still intact. In another patient, the nervus suralis was damaged during surgery by piercing the tension suture at the near end, causing postoperative numbness and swelling. The tension suture was quickly removed, and the patient recovered well with conservative treatment. No large irregular scars, such as those sustained during immobilization, were present over the Achilles tendon. Minimally invasive percutaneous suturing can restore the original length and continuity of the Achilles tendon, is minimally invasive, and results in fewer postoperative complications than other methods.

PURPOSE: Cervical carcinoma is the second most prevalent and the fifth most deadly malignancy seen in women worldwide. Dysregulated activation of EGF ErbB system has been implicated in diverse types of human cancer; however, it is elusive how it is regulated in human cervical cancer cells. We herein aimed to explore the mechanisms of cervical carcinoma response to epidermal growth factor (EGF), with a view of the pathways activated by EGF. METHODS: Using the GSE6783 affymetrix microarray data accessible from gene expression omnibus database, we first identified the differentially expressed genes between EGF-stimulated and -unstimulated samples. Then we constructed a regulation network and identified the network motifs. We also performed biological process and pathway enrichment analyses to functionally classify the genes in the regulation network. RESULTS: A total of 11 network motifs were identified in the regulation network. EGF treatment could increase the risk of cancer via dysregulation of cancer-related pathways and immune response pathways. CONCLUSIONS: Network motif analysis is useful in mining the useful information underlying the network. We hope our work could serve as a basis for further experimentation.

BACKGROUND: MicroRNAs (miRNAs) exist pervasively across viruses, plants and animals and play important roles in the post-transcriptional regulation of genes. In the common carp, miRNA targets have not been investigated. In model species, single-nucleotide polymorphisms (SNPs) have been reported to impair or enhance miRNA regulation as well as to alter miRNA biogenesis. SNPs are often associated with diseases or traits. To date, no studies into the effects of SNPs on miRNA biogenesis and regulation in the common carp have been reported. RESULTS: Using homology-based prediction combined with small RNA sequencing, we have identified 113 common carp mature miRNAs, including 92 conserved miRNAs and 21 common carp specific miRNAs. The conserved miRNAs had significantly higher expression levels than the specific miRNAs. The miRNAs were clustered into three phylogenetic groups. Totally 394 potential miRNA binding sites in 206 target mRNAs were predicted for 83 miRNAs. We identified 13 SNPs in the miRNA precursors. Among them, nine SNPs had the potential to either increase or decrease the energy of the predicted secondary structures of the precursors. Further, two SNPs in the 3' untranslated regions of target genes were predicted to either disturb or create miRNA-target interactions. CONCLUSIONS: The common carp miRNAs and their target genes reported here will help further our understanding of the role of miRNAs in gene regulation. The analysis of the miRNA-related SNPs and their effects provided insights into the effects of SNPs on miRNA biogenesis and function. The resource data generated in this study will help advance the study of miRNA function and phenotype-associated miRNA identification.

OBJECTIVE: To explore the correlation between induced abortion and reproductive tract infections (RTIs). METHODS: On the basis of keeping the representation of cities under study, 53 652 fertile women aged 15 - 49 were surveyed by using a stratified-cluster-random sampling. Investigation and gynecological examination were conducted by two steps - firstly converging at the clinics, and then visiting those households for someone who did not show up at the clinics. RESULTS: Among all the 32.0% (n=16 800) women ever having experienced the history of induced abortion, 21.1% (n = 11 090) of them had one, 7.6% (n=3976) women had two, and 4.1% (n=1734) women had at least three events. 59.0% (n=30 959) women among our studied samples had ever had RTI, with 30.9% (n=16 215) of them had only one 20.0% (n=10 494) women had two and 8.1% (n=4250) had three or more RTIs. Data from χ(2) text and ordinal regression analysis revealed that the rural married women who underwent more induced abortions were more likely to suffer from RTIs, especially cervical infection and PID. CONCLUSION: Our study showed that the rates of induced abortion and reproductive tract infections among married women in Anhui province were both high. Women who underwent induced abortions had a higher prevalence rate of reproductive tract infections.
