Abstract
Objective: To analyze the epidemiological characteristics of adult inpatients with gas burns in the Department of Burns of Hwa Mei Hospital of University of Chinese Academy of Sciences (hereinafter referred to as the author's unit) , so as to provide evidence for the prevention of gas burn. Methods: Medical records of all inpatients with flame burns admitted to the author's unit from January 2011 to December 2017 were collected. The percentage of adult inpatients with gas burns in total inpatients with flame burns in the same period, and their gender, age, injury season, accident place, burn severity, common compound injury, complication, population caliber, education, industry, as well as the pre-injury disease and prognosis of elderly inpatients with gas burns were retrospectively analyzed. In addition, the age, accident place, education, and industry of the floating population in the adult inpatients with gas burns were analyzed separately and compared with the total population of adult inpatients with gas burns in 7 years. Data were processed with chi-square test or Fisher's exact probability test (Monte Carlo algorithm). Results: During the 7 years, 1 490 inpatients with flame burns were admitted to the author's unit, among which 511 were adult inpatients with gas burns, accounting for 34.30%. The number of adult inpatients with gas burns increased gradually during the 7 years, but its percentage in the total inpatients with flame burns during the same period showed no significant difference (χ(2)=7.087, P>0.05). Among the 511 adult inpatients with gas burns (hereinafter referred to as the patients in this group), there were 315 males and 196 females, with a male/female ratio of 1.61 to 1.00, and the middle-aged patients were the most, up to 270 cases, accounting for 52.84%. The distribution of adult inpatients with gas burns during the 7 years was significantly different in gender and age (χ(2)=54.810, 27.832, P<0.01). Among the patients in this group, most were injured in summer, totally 251 cases, accounting for 49.12%, and the accident place was mainly at home, totally 388 cases, accounting for 75.93%. The distribution of adult inpatients with gas burns during the 7 years was significantly different in injury season (χ(2)=42.254, P<0.01), but not in accident place (χ(2)=6.782, P>0.05). The patients in this group were mainly with moderate burns (237 cases, accounting for 46.38%), and the distribution trend of burn severity of adult inpatients with gas burns was basically the same during the 7 years (χ(2)=19.680, P>0.05); 176 patients (34.44%) were accompanied by inhalation injury, and 30 patients (5.87%) were accompanied by blast injury of lung; post injury complications occurred in 20 patients (3.91%). In the elderly inpatients with gas burns, 44.44% (32/72) were accompanied by pre-injury basic diseases, and the proportion of death or unhealed reached 18.06% (13/72). Most of the patients in this group were permanent residents (358 cases, accounting for 70.06%) and received secondary education (304 cases, accounting for 59.49%), and the majority of them were engaged in manufacturing/construction (138 cases, accounting for 27.01%), self-employed business (90 cases, accounting for 17.61%), and catering (90 cases, accounting for 17.61%) industries. The distribution of adult inpatients with gas burns during the 7 years was significantly different in population caliber, education, and occupation (χ(2)=17.496, 29.898, 88.896, P<0.05 or P<0.01). Among the patients of this group, the floating population were mainly young (90 cases, accounting for 58.82%) and middle-aged (62 cases, accounting for 40.52%), with main accident place at home (97 cases, accounting for 63.40%), generally received secondary education (101 cases, accounting for 66.01%), and were mainly engaged in manufacturing/construction (71 cases, accounting for 46.41%), self-employed business (26 cases, accounting for 16.99%), and catering (20 cases, accounting for 13.07%) industries. Compared with the total adult inpatients with gas burns in 7 years, the floating population were younger, more injured in the workplace, and more concentrated in industry (χ(2)=42.924, 9.390, 27.819, P<0.01). Conclusions: Gas burn was the leading injury cause of inpatients with flame burns in the author's unit, which mainly occurred in summer and at home; the patients were mainly male, young and middle-aged, and permanent residents, most of which were with moderate burn, often accompanied by inhalation injury. Most of the patients were of secondary education, engaged in manufacturing/construction, self-employed business, and catering industries, among which the floating population were younger, more injured in the workplace, and more concentrated in industry. In order to prevent gas burn, we should pay more attention to the propaganda and education of gas safety among young and middle-aged men, floating population, retired old people and housewives, especially in summer, we should do a good job in gas safety inspection at home. In addition, we should urge enterprises to further strengthen the supervision of production safety.

Abstract
Growth and fatness traits are complex and economically important traits in the pig industry. The molecular basis underlying porcine growth and fatness traits remains largely unknown. To uncover genetic loci and candidate genes for these traits, we explored the GeneSeek GGP Porcine 80K SNP chip to perform a GWAS for seven growth and fatness traits in 365 individuals from the Sujiang pig, a recently developed breed in China. We identified two, 17, one and 11 SNPs surpassing the suggestively significant threshold (P < 1.86 × 10-5 ) for body weight, chest circumference, chest width and backfat thickness respectively. Of these SNPs, 20 represent novel genetic loci, and five and four SNPs were respectively associated with chest circumference and backfat thickness at a genome-wide significant threshold (P < 9.31 × 10-7 ). Eight SNPs had a pleiotropic effect on both chest circumference and backfat thickness. The most remarkable locus resided in a region between 72.95 and 76.27 Mb on pig chromosome 4, harboring a number of previously reported quantitative trait loci related to backfat deposition. In addition to two reported genes (PLAG1 and TAS2R38), we identified four genes including GABRB3, ZNF106, XKR4 and MGAM as novel candidates for body weight and backfat thickness at the mapped loci. Our findings provide insights into the genetic architecture of porcine growth and fatness traits and potential markers for selective breeding of Chinese Sujiang pigs.

Abstract
Objective To develop a high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for the determination of the content of 4-fluoromethamphetamine (4-FMA) in rat plasma, and to provide a methodological basis for the study of the toxicokinetics of 4-FMA in rats. Methods Rat plasma samples were added into internal standard methamphetamine (MA). Its proteins were precipitated with methanol and then separated with Poroshell 120 EC-C18 chromatographic column. A 0.1% formic acid aqueous solution and a 0.1% formic acid acetonitrile solution were used as the mobile phase at the flow rate of 0.4 mL/min. Electrospray ionization source was used for detection in the multiple reaction monitoring (MRM) mode. Results The linear relationship was good when the mass concentration of 4-FMA in plasma samples was in the range of 5-1 000 ng/mL (r>0.999). The limit of detection (LOD) was 3 ng/mL and the limit of quantification (LOQ) was 5 ng/mL. The accuracy was expressed as relative error (RE), and in the range of ±5%, the intra-day precision and inter-day precision (relative standard deviation, RSD) less than 9%, and the extraction recovery rate was more than 90%. The analysis and detection of plasma samples were completed within 2.5 min. Conclusion This study developed a HPLC-MS/MS method for the determination of 4-FMA in rat plasma samples. This method is accurate, rapid, simple and sensitive and can be applied to the study of toxicokinetics of 4-FMA.

Abstract
Objective: To investigate the effect of birth ball on the outcome of COOK balloon induction. Methods: A total of 580 patients were hospitalized in the obstetrics department of Jiaxing Maternal and Child Health Hospital from May 1, 2017 to December 31, 2017. According to the patient's wishes, 290 cases of cervical ripening with birth ball combined with COOK balloon were taken as experimental group, and 290 cases of cervical ripening group with COOK balloon were set as control group. Bishop score improvement, labor time, cesarean section rate, delivery forceps rate, postpartum hemorrhage, and neonatal scores were compared between the two groups of patients. Results: (1)There was no significant difference in the ag, Body Mass Index (BMI), education background, registered residence and gravidity between the two groups (P>0.05). (2)There was no significant difference in Bishop score improvement between the two groups (P>0.05). (3)The labor time in the experimental group (8.4 h±1.5 h)was significantly shorter than that in the control group (10.6 h±2.7 h). The differences were statistically significant (P<0.05). The cesarean section rate (11.03% vs 15.17%), forceps delivery rate (5.52% vs 8.28%), and postpartum hemorrhage (308 ml±9 ml vs 367 ml±16 ml) were significantly lower in the experimental group than in the control group. The differences were statistically significant (P<0.05). Conclusion: The application of the birth ball in the induction of the COOK balloon can shorten the labor time, reduce the cesarean section rate and the forceps delivery rate, and reduce the postpartum hemorrhage, which has certain clinical application value.

Abstract
Broomcorn millet (Panicum miliaceum L.) is one of the oldest domesticated crops and has been grown in arid and semiarid areas in China since 10,000 cal. BP. However, limited information is available about how bacterial communities within the rhizosphere of different broomcorn millet cultivars respond to drought stress. Here, we characterized the changes in the rhizobacterial assemblages of two broomcorn millet cultivars, namely, P. miliaceum cv. HeQu Red (HQR) and P. miliaceum YanLi 10 (YL10), from the jointing stage to the grain filling stage after they were exposed to a short-term drought stress treatment at the seedling stage. Drought significantly inhibited the growth of both cultivars, but the effect on YL10 was higher than that on HQR, indicating that the drought tolerance of HQR was greater than that of YL10. Proteobacteria (33.8%), Actinobacteria (21.0%), Acidobacteria (10.7%), Bacteroidetes (8.2%), Chloroflexi (6.3%), Gemmatimonadetes (5.9%), Firmicutes (3.5%), Verrucomicrobia (2.9%), and Planctomycetes (2.7%) were the core bacterial components of broomcorn millet rhizosphere as suggested by 16S rDNA sequencing results. The diversity and composition of bacterial rhizosphere communities substantially varied at different developmental stages of broomcorn millet. As the plants matured, the richness and evenness of the rhizobacterial community significantly decreased. Principal coordinate analysis showed that the structure of the bacterial rhizosphere community changed notably only at the flowering stage between the two cultivars, suggesting a stage-dependent effect. Although drought stress had no significant effect on the diversity and structure of the bacterial rhizosphere community between the two cultivars, differential responses to drought was found in Actinobacteria and Acinetobacter, Lysobacter, Streptomyces, and Cellvibrio. The relative abundance of Actinobacteria and Lysobacter, Streptomyces, and Cellvibrio in the YL10 rhizosphere was stimulated by the drought treatment compared with that in the HQR rhizosphere, whereas the opposite effect was found in Acinetobacter. Our results suggested that the effects of cultivars on bacterial rhizosphere communities were highly dependent on plant developmental stage, reflecting the genetic variations in the two broomcorn millet cultivars.

Abstract
BACKGROUND The DASH (Dietary Approaches to Stop Hypertension) diet serves as a dietary pattern for the prevention and control of hypertension. The present study aimed to investigate whether the DASH diet can improve the outcomes of pregnancy with gestational hypertension (GH) and chronic hypertension. METHODS The current randomised controlled clinical trial was performed in 85 pregnant women diagnosed with GH and chronic hypertension between July 2015 and December 2017. The women were categorised into a control group (41 cases) and a DASH group (44 cases). Participants were followed until delivery. The clinical outcomes of mothers included gestational weeks of birth, delivery mode, postpartum haemorrhage and GH, as well as the incidence of pre-eclampsia during the second and third trimesters. Newborn measurements were collected by evaluating prematurity, birth weight, body length and neonatal Apgar score. RESULTS The incidence of pre-eclampsia, prematurity and low birth weight in the DASH group was lower than that in the control group (P < 0.05). Significant differences were also observed in gestational age at delivery and the newborn body length between the two groups (P < 0.05). We failed to find a significant difference in changes of delivery mode, postpartum haemorrhage, postpartum GH, mean birth weight and Apgar score (P > 0.05) between the two diets. CONCLUSIONS A DASH diet might comprise a potential strategy for improving the clinical outcomes in pregnant women with GH and chronic hypertension. Future robust clinical trials are warranted to corroborate these findings.

Abstract
OBJECTIVE Circular RNAs (circRNAs) are involved in cancer progression and metastasis, although little is known about their role in glioblastoma (GBM). The aim of this study was to investigate the expression pattern and molecular mechanism of hsa_circ_0067934 in GBM. PATIENTS AND METHODS Hsa_circ_0067934 expression was detected in GBM tissues and cell lines by using RT-PCR. The prognostic value of the hsa_circ_0067934 expression in GBM patients was statistically analyzed. The effects of hsa_circ_0067934 expression on growth and apoptosis of GBM cells were analyzed by CCK-8, colony formation, and flow cytometry. Migration and invasion ability was evaluated by transwell and wound-healing assays. The protein expression of signaling pathways was determined by using Western blot. RESULTS The expression level of hsa_circ_0067934 was significantly increased in GBM tissues and cancer cells. Kaplan-Meier survival curves showed that patients with higher expression of hsa_circ_0067934 had a more favorable overall survival and disease-free survival. The functional investigations revealed that the knockdown of hsa_circ_0067934 suppressed GBM cell proliferation, metastasis and EMT, and promoted apoptosis. Moreover, the mechanistic analysis demonstrated that the down-regulation of hsa_circ_0067934 significantly suppressed the activation of the PI3K-AKT pathway. CONCLUSIONS Hsa_circ_0067934 is overexpressed and plays an oncogenic role in GBM by promoting cancer cell proliferation and metastasis via upregulation of PI3K-AKT pathway, which suggests that hsa_circ_0067934 is likely to serve as an efficient therapeutic approach in respect of GBM treatment.

Abstract
Mammalian target of rapamycin (mTOR) is a serine/threonine protein kinase in the downstream of the phosphatidylinositol 3-kinases (PI3K) family. This kinase plays an important role in the development and progression of hepatocellular carcinoma (HCC). Preclinical data demonstrate that 40%-50% of HCC patients have dysregulated expression of the effectors of the mTOR signaling pathway, and the activation of the mTOR pathway is associated with poorly differentiated tumors, early tumor recurrence, and poor survival/prognosis. This article reviews the research advances in the potential role of the mTOR signaling pathway and its inhibitors in the treatment of HCC.

Abstract
This study aimed to investigate the role of RNF8 (RING finger protein 8) in DNA damage repair in mice of different ages, and to provide new insight into the pathology and treatment of senile deafness. Sixteen C57BL/6J mice aged 8 weeks, 16 weeks and 32 weeks were obtained by paired reproduction. The mice of three age groups were equally divided into two groups, named experimental group (RNF8 gene knockout) and control group (no knockout). The cochlear hair cells, stria vascularis and spiral ganglion cells were observed by HE (hematoxylin-eosin) staining. The degree of DNA damage and the related expressions were observed by immunofluorescence γ-H2AX staining and 8-OH immunohistochemical staining, and the aging of damaged cells was detected by lipofuscin and β-galactosidase staining. HE staining showed that the changes of cochlear hair cells, stria vascularis and spiral ganglion cells were obvious in the same group of mice at different ages. Compared with the control group, the aging changes of cochlear hair cells, stria vascularis and spiral ganglion cells were more significant in the experimental group. Immunofluorescence γ-H2AX staining showed H2AX phosphorylation in injured cells. The aging of cochlea in mice changed, and staining of β-galactosidase in the experimental group suggested that the striae of blood vessels were changed with age at 32 weeks old and staining of lipofuscin showed dark brown staining around the nucleus (P < 0.05). In conclusion, the deletion of RNF8 is an important cause of morphological changes in the cochlea of mice. The deletion of RNF8 accelerates the aging of the cochlea of mice, suggesting that the apoptosis of the cochlea could contribute to aging in RNF8 gene-deficient mice.

Abstract
Objective: To study the epidemiological characteristics and latent classes of non-marital heterosexual transmission among human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) individuals in Jiangmen, Guangdong province between 2015 and 2017. Methods: HIV/AIDS cases from Chinese HIV/AIDS Comprehensive Response Information Management System were collected from January 1, 2015 to December 31, 2017. Inclusion criteria of HIV/AIDS were heterosexual transmission, non-marital heterosexual contact and older than 15 years. Exclusion criteria were homosexual contact, repeated reports, injecting drugs, current address in the non-Jiangmen area and not classified non-marital heterosexual contact. A total of 665 HIV/AIDS cases were included in this study. The general demographic characteristics (gender, age, ethnicity, education, occupation, etc.), floating population characteristics, HIV high-risk behaviors, HIV testing and other information were collected from database. Chi square test was used to compare the infection status of HIV/AIDS with different characteristics through commercial channels, and the latent class model was used to analyze the latent classes of HIV/AIDS. Results: Among 665 cases, the age was (48.73±15.61) years old. And 46.5% (309/665) cases were married and 73.8% (491/665) were male. Four classes were identified as heterogeneous sub-population by the latent class analysis: the first class occupied 40.13% (267 cases) with feature of nearly equal proportion of males and females and higher proportion of non-service industry workers; the second class occupied 37.40% (248 cases) with features of more than 46 years old, nearly all males, high proportion of farmers, high proportion of marital status, low education and the low propensity of floating; the third class occupied 11.90% (79 cases) with feature of cases from voluntary HIV testing and counseling in center for disease control and prevention; the forth class occupied 10.57% (70 cases) with the feature of less 45 years old, high proportion of service industry workers, no marital history and higher education. Conclusions: HIV/AIDS transmitted by non-marital heterosexual sex in Jiangmen city during 2015-2017 could be divided into four latent classes according to epidemic characteristics, which could provide appropriate classified guidance for AIDS prevention and treatment.

Abstract
Pig umbilical hernia (UH) affects pig welfare and brings considerable economic loss to the pig industry. To date, the molecular mechanisms underlying pig UH are still poorly understood. To identify potential loci for susceptibility to this disease, we performed a genome-wide association study in an Erhualian × Shaziling F2 intercross population. A total of 45 animals were genotyped using Illumina Porcine SNP60 BeadChips. We observed a SNP (rs80993347) located in the calpain-9 (CAPN9) gene on Sus scrofa chromosome 14 that was significantly associated with UH (P = 1.97 × 10-10 ). Then, we identified a synonymous mutation rs321865883 (g.20164T>C) in exon 10 of the CAPN9 gene that distinguished two affected individuals (CC) from their normal full-sibs (TC). Finally, quantitative polymerase chain reaction was explored to investigate the mRNA expression profile of the CAPN9 gene in 12 tissues in Yorkshire pigs at different developmental stages (3, 90 and 180 days). CAPN9 showed high expression levels in the gastrointestinal tract at these three growth stages. The results of this study indicate that the CAPN9 gene might be implicated in UH. Further studies are required to establish a role of CAPN9 in pig UH.

Abstract
Objective: To construct a recombinant short-hairpin RNA (shRNA) lentiviral vector targeting the β-catenin gene in cochlear precursor cells (CPCs) in mice, and to investigate its inhibitory effect. Methods: PCR was used for the multiplication of the β-catenin gene, and shRNA oligo was designed based on the β-catenin gene to construct an interference vector. Gateway Technology was used to construct shRNA lentiviral vector which carried the β-catenin gene, and then 293FT cells were transfected with the constructed lentiviral vector and helper plasmids pLV/helper-SL3, pLV/helper-SL4, and pLV/helper-SL5. The virus supernatant was collected to obtain viral particles, and then mouse CPCs were transiently infected with the recombinant lentivirus with four different concentrations (0, 5, 10, and 20 μl) . The shRNA control group was established. Quantitative real-time PCR and Western blot were used to investigate the inhibitory effect of shRNA β-catenin lentiviral vector on β-catenin. Results: The recombinant shRNA β-catenin lentiviral vector was successfully constructed, and the virus titers of shβ-catenin and shβ-catenin-control were 5.05×10(7) and 4.34×10(7), respectively. The results of in vitro experiments showed that in CPCs transfected with four different concentrations of recombinant lentivirus, the content of β-catenin protein gradually decreased with the increase in concentration, and there was a significant difference between groups (P<0.05) ; the CPCs transfected with shβ-catenin had significantly lower mRNA expression of β-catenin than those in the shβ-catenin-control group (P<0.05) . Conclusion: The constructed lentiviral vector targeting the β-catenin gene has a high infection efficiency, and the successful construction of lentiviral vectors provides a technical support for analyzing the role of β-catenin in the differentiation of CPCs into auditory hair cells.

Abstract
Gastric cancer (GC), the third leading cause of cancer mortality and the fifth most common cancer in the world, still is an important health problem worldwide. P53-inducible gene 3 (PIG3) was initially isolated in an investigation to identify the genes that were induced by p53 in human colorectal cancer cells. PIG3 can also regulate the stability of p53 through suppressing the process of the MDM2-mediated ubiquitination of p53. The aim of this study is to explore the expression level of PIG3 in human GC and further investigate the function and mechanism of PIG3 in human GC. Five cell lines and 30 matched GC tissue samples and adjacent tissue samples were used for this study, and MTT assay, colony formation assay, flow cytometry analysis and Western blot were carried out. Expression of PIG3 was found to be frequently reduced in GC. Restoration of the expression of PIG3 inhibited cell proliferation, induced cell apoptosis and further activated P53 signaling in BGC823 cells. In conclusion, we demonstrated that expression of PIG3 is frequently reduced in GC tissue, and PIG3 suppressed human GC growth through p53- mediated apoptosis. PIG3 may act as a potential diagnostic marker and a potential therapeutic target of GC.
