Abstract
BACKGROUND Ventriculitis, one of the difficulties in neurosurgical treatment, is a significant cause of death and morbidity in patients with hydrocephalus. Neuroendoscopy is widely used in the treatment of non-communicable hydrocephalus. The advantages of neuroendoscopy may play a decisive role in the treatment of ventriculitis. CASE REPORT AND METHODS We report a 34-year-old male patient with refractory fever and rapid progressive disturbance of consciousness due to ventriculitis caused by intraventricle rupture in a left colliculus abscess. He received intravenous (IV) antibiotics and saline neuroendoscopic lavage (NEL) combined with septostomy and endoscopic third ventriculostomy leading to rapid recovery and remission of symptoms. We also reviewed the use of NEL for ventriculitis in PubMed from 1970 to January 20, 2019. RESULTS In our review, 93 cases (including the present report) were treated with NEL; 91 cases of infection subsided, and 7 patients died. CONCLUSION NEL may be an effective method for the treatment of ventriculitis.

Abstract
Salinity represents a serious environmental threat to crop production and by extension, to world food supply, social and economic prosperity of the developing world. Salicylic acid (SA) is an endogenous plant signal molecule involved in regulating various plant responses to stress. In the present study, we characterized the regulatory role of exogenous SA for their ability to ameliorate deleterious effects of salt stress (0, 100, 150, 200 mM NaCl) in choysum plants through coordinated induction of antioxidants, ascorbate glutathione (AsA-GSH) cycle, and the glyoxalase enzymes. An increase in salt stress dramatically declined root and shoot growth, leaf chlorophyll and relative water content (RWC), subsequently increased electrolyte leakage (EL) and osmolytes accumulation in choysum plants. Salt stress disrupted the antioxidant and glyoxalase defense systems which persuaded oxidative damages and carbonyl toxicity, indicated by increased H2O2 generation, lipid peroxidation, and methylglyoxal (MG) content. However, application of SA had an additive effect on the growth of salt-affected choysum plants, which enhanced root length, plant biomass, chlorophyll contents, leaf area, and RWC. Moreover, SA application effectively eliminated the oxidative and carbonyl stress by improving AsA and GSH pool, upregulating the activities of antioxidant enzymes and the enzymes associated with AsA-GSH cycle and glyoxalase system. Overall, SA application completely counteracted the salinity-induced deleterious effects of 100 and 150 mM NaCl and partially mediated that of 200 mM NaCl stress. Therefore, we concluded that SA application induced tolerance to salinity stress in choysum plants due to the synchronized increase in activities of enzymatic and non-enzymatic antioxidants, enhanced efficiency of AsA-GSH cycle and the MG detoxification systems.

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.

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
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 investigate the effects of ethylbenzene on growth morphology、proliferation ability and mitochondrial membrane potential (MMP) of cochlear progenitor cells (CPCs) , and to lay a foundation for the mechanism of hearing loss induced by ethylbenzene. Methods: We can use the fluorescence microscopy to identify the original CPCs isolated from the newborn rats, and followed by the addition of different concentrations of ethylbenzene (0, 15, 30, 45 μmol/L) for 24 hours. The morphological changes of cell injury were observed by inverted optical microscope. The proliferation ability of cells was detected by MTT colorimetry, and the change of MMP was detected by fluorescent probe JC-1. Results: The results of CPCs identification showed the expression of Myosin VIIa and Epsin positive; The results observed by inverted optical microscope showed all groups of CPCs morphological changes compared with the control group; MTT results showed that the decreased significantly proliferation ability of CPCs groups compared with the control group and a dose effect relationship with statistically significant difference (P<0.05) ; JC-1 test results showed the decreased significantly mitochondrial membrane potential in the treated group compared with the control group, and there was a statistically significant difference (P<0.05) . Conclusion: Ethylbenzene may cause damage to CPCs, inhibition of cell proliferation and decrease of MMP in rats.
