Abstract
The Chinese white pine beetle Dendroctonus armandi (Coleoptera: Scolytinae) typically displays bivoltinism at altitudes below 1700 m in the Qinling Mountains, China. The periods of host colonization and larval overwintering are two important phases in the life cycle of bark beetles, as it is during these periods that they have to contend with host plant defences and periods of intense cold, respectively. Although during different seasons, the females and males of Chinese white pine beetles show varying tolerances to host plant terpenoids, the sex ratio and survival physiology condition of the two beetle generations are unknown. We investigated the sex ratio of individuals, and also examined the body mass, energy stores, and detoxication enzymes of males and females in each of the two generations in order to determine the overall population stability of each generation. We identified a female-biased sex ratio among adults in both generations. Furthermore, patterns of body mass, energy stores, and detoxication enzymes were found to differ between the two sexes and two seasons. Compared with the males, the females have a larger body mass and higher amounts of stored lipids, which are assumed to be adaptations designed to overcome host resistance and facilitate subsequent oviposition.

Abstract
Objective: To analyze the causes of complications after endoscopic transsphenoidal pituitary adenoma resection and summarize the corresponding prevention and treatment measures. Methods: The pathological data of 120 patients with pituitary adenoma in hospital were analyzed retrospectively. All patients were treated surgically, five kinds of common complications were collected, the risk factors of complications were statistically analyzed, the causes of postoperative complications were determined, and then the specific prevention and treatment strategies were summarized. Results: Long operation time (P<0.05), hypopituitarism before operation (P<0.01) and large tumor (P<0.01) were the main inducing factors of CSF rhinorrhea after operation; long operation time (OR=1.394, P<0.01), lumbar cistern puncture (OR=1.531, P<0.01) and CSF rhinorrhea after operation (OR=3.861, P<0.01) were the independent risk factors of infection; Age, large tumor and preoperative hypophysis are the main factors of postoperative hypophysis; Postoperative hypophysis and intraoperative cerebrospinal fluid rhinorrhea are the main factors of postoperative diabetes insipidus; Postoperative hypophysis and giant adenoma are the main factors of postoperative hyponatremia. Conclusion: Endoscopic transnasal transsphenoidal resection of pituitary adenoma is the most minimally invasive method at present. There are still risk factors for postoperative complications. Targeted prevention of risk factors for complications and corresponding interventions can effectively reduce the incidence of postoperative complications of pituitary adenoma.

Abstract
IκB kinase α (IKKα) is associated with tumourigenesis, metastasis, and poor prognosis. However, its expression and function in oral squamous cell carcinoma (SCC) remain unknown. The aim of this study was to elucidate the clinicopathological associations and functions of IKKα in oral squamous cell carcinoma (SCC). We made an immunohistochemical analysis of IKKα in 94 tissue microarrays of specimens of oral SCC. We also examined IKKα expression in the patients' samples by quantitative real-time polymerase chain reaction (qRT-PCR), as well as the migration, invasion, and matrix metalloproteinase (MMP) activity of the cells under IKKα knockdown treatment. In oral SCC, immunostaining for IKKα was found in 60 of the 94 patients, and it correlated with lymph node status and poor prognosis. Univariate and multivariate analysis using Cox's proportional hazards model identified that IKKα expression was an independent predictor of distant- disease-free survival (p<0.05) and overall survival in oral SCC (p<0.05). Knocking down IKKα suppressed cell migration and invasion in oral SCC cells. Our results indicate that IKKα has an important role in promoting oral SCC, and it may be a useful biomarker and therapeutic target for diagnosis and treatment.

Abstract
This study investigated the effects of Lactobacillus plantarum (Lp) and Bifidobacterium animalis ssp. lactis (Ba) in co-cultures with Streptococcus thermophilus (St) on changes in the acidification profile, proteolytic activity, peptide production, in vitro antioxidant activity, and angiotensin-converting enzyme (ACE) inhibitory properties of fermented milks during 21 d of storage at 4°C. The pH values and proteolysis in all batches showed a gradual decrease and increase during storage, respectively. The ACE-inhibitory activity and total antioxidant capacity of all co-fermented milk samples followed a similar pattern, with maximum values on d 6 of storage. The St starter, in conjunction with Ba or Lp or both, enhanced proteolysis, peptide generation, and ACE-inhibitory and antioxidant activity, but decreased pH values compared with St alone. The St-Ba-Lp samples showed higher DPPH• (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity, hydroxyl radical scavenging activity, and total antioxidant capacity, but similar superoxide anion scavenging activity compared to St-Ba or St-Lp samples. The St-Ba samples showed higher DPPH• radical scavenging activity but lower hydroxyl radical scavenging activity than St-Lp samples. In the ACE-inhibitory assays, the St-Lp samples exhibited relatively low activity among the co-fermented milks, digested or not. The presence of Ba and Lp in fermentation together did not affect ACE-inhibitory activity in undigested fermented milks compared with the presence of Ba alone, and St-Ba-Lp fermented milks demonstrated an increase in ACE-inhibitory activity after simulated gastrointestinal digestion in storage. Pepsin digestion largely improved ACE-inhibitory activity, except in St-Lp samples, in which the activity was reduced. Further hydrolysis by trypsin reduced final activity in digestion. This study suggests that co-cultured fermentation with probiotics improves in vitro antioxidant and ACE inhibition activity in fermented milks, and this effect is partly due to the higher proteolytic activity of probiotics.

Abstract
AIMS To develop a pcsB-based Loop-mediated isothermal amplification (LAMP) method for the detection of Streptococcus agalactiae (GBS) in milk, tilapia and vaginal swabs. METHODS AND RESULTS The sensitivity of the LAMP method using real-time turbidity monitoring was 1 pg of template within 1 h at 64°C, 100-fold higher than conventional PCR. The sensitivity of visual detection dropped an order of magnitude using SYBR Green I or hydroxynaphthol blue. The validity of the visual LAMP assay was assessed by the detection of GBS in 180 vaginal swabs from one hospital, 14 brain tissues samples of diseased tilapias from two fishponds and fresh milk of 67 dairy cattle from one farm. In total, 17 samples (4 vaginal swabs, 13 tilapia brain tissues but no milk sample) tested positive for GBS. Subsequent bacterial identification confirmed the specificity and reliability of the LAMP method. Molecular serotyping and multilocus sequence typing demonstrated that all 13 tilapia GBS isolates were identical (serotype Ia, ST7), whereas the four human GBS isolates were more diverse and could be classified into two serotypes (Ia, III) and four sequence types (ST19, ST23, ST24, ST862). Virulence gene testing showed that only the bac, rib and lmb genes were not present in all isolates. Antimicrobial susceptibility profiles of the isolates were basically consistent with their genotypes, except for sulphonamide and fluoroquinolone. CONCLUSIONS We developed a reliable pcsB-based LAMP assay for GBS detection. Our results demonstrated that the prevalence of GBS was 92·9% among diseased tilapia, 2·2% among female patients and 0% on a dairy farm in Hainan. SIGNIFICANCE AND IMPACT OF THE STUDY The pcsB-based LAMP method is suitable for GBS detection and contains great potential of application in dairy industry, aquiculture and clinical.

Abstract
OBJECTIVE To investigate the correlations of serum vascular endothelial growth factor (VEGF) and matrix metalloproteinase-2 (MMP-2) levels with colorectal liver metastasis (CLM) in patients with colorectal cancer (CRC), and determine the effects of transhepatic arterial chemoembolization (TACE) on their expressions. PATIENTS AND METHODS A total of 110 CRC patients treated in the department of interventional radiology of our hospital from May 2013 to May 2016 were randomly enrolled. All patients received treatment of TACE after surgery. During surgery, 10 mL venous blood was taken, and the protein levels of VEGF and MMP-2 in serum were detected via enzyme-linked immunosorbent assay (ELISA). The correlations of VEGF and MMP-2 levels with clinicopathological features of patients were analyzed. The values of VEGF and MMP-2 in predicting CLM were analyzed using the receiver operating characteristic (ROC) curve. Moreover, changes in serum VEGF and MMP-2 levels in CRC patients were analyzed before TACE, and at 1 and 6 months after TACE. RESULTS The median VEGF and MMP-2 levels in serum of CRC patients were 64.8 ng/mL and 114.4 ng/mL, respectively, which were significantly higher than those in healthy control group (5.3 ng/mL and 6.8 ng/mL) (p<0.05). The expressions of VEGF and MMP-2 in serum of CRC patients were correlated with the depth of tumor infiltration, Dukes' staging, CLM and lymph node metastasis (p<0.05). Logistic regression analyses showed that the expression levels of VEGF and MMP-2 were positively correlated with CLM (p<0.05). The ROC curve revealed that the sensitivity, specificity and accuracy of serum VEGF in the diagnosis of CLM were 62.2%, 78.5% and 80.2%, respectively. The sensitivity, specificity and accuracy of serum MMP-2 in the diagnosis of CLM were 68.9%, 85.5% and 82.2%, respectively. The serum VEGF levels in CRC patients before TACE, and at 1 and 6 months after TACE were (64.8±58.8) ng/mL, (43.1±27.3) ng/mL and (24.8±12.3) ng/mL, respectively, showing a downward trend (p<0.05). The serum MMP-2 levels in CRC patients before TACE, and at 1 and 6 months after TACE were (114.4±136.2) ng/mL, (73.4±58.5) ng/mL and (39.6±30.4) ng/mL, respectively, also indicating a reducing trend (p<0.05). CONCLUSIONS The levels of VEGF and MMP-2 in portal vein serum of CRC patients can be used as effective indexes for judging the prognosis of CRC and predicting CLM. Patients with high expression of VEGF and MMP-2 should be actively treated with TACE after surgery to improve the survival rate.

Abstract
AIM To determine the cut-off value of the area ratio under the curve (ARUC) for predicting symptoms of stroke. MATERIALS AND METHODS Contrast-enhanced ultrasound was used to analyse intraplaque neovascularization (IPN). The correlations between the ARUC and risk factors of stroke were examined. A receiver operating characteristic curve was used to determine the cut-off value of the ARUC. RESULTS Using a quantitative analysis method for IPN, the ARUC was significantly higher in the symptomatic group than in the asymptomatic group (p=0.017). The ARUC was positively associated with the homocysteine level (r=0.429, p=0.002) and high-sensitivity C-reactive protein level (r=0.424, p=0.003). Regression analysis showed that the ARUC was a risk factor for symptoms of stroke. The receiver operating characteristic curve showed that the cut-off value for symptoms was 0.24; the sensitivity was 77%, and the specificity was 70%; the positive predictive value was 68%, and the negative predictive value was 78%. CONCLUSION IPN was a risk factor for the occurrence of the clinical symptoms of stroke. Patients with an ARUC of >0.24 had a higher risk of stroke.

Abstract
Background This study evaluated the diagnostic performances of total and high-avidity (HA) anti-dsDNA enzyme immunoassays (EIA) in Chinese systemic lupus erythematosus (SLE) patients. Methods A total of 410 serum samples from 217 SLE patients, 54 patients with other systemic autoimmune diseases, and 139 healthy subjects were tested on total and HA anti-dsDNA EIA, as well as three commercial in vitro diagnostic kits: BioPlex 2200 ANA Screen, Kallestad anti-dsDNA EIA, and Crithidia Lucilae IFA. The disease activities of SLE patients were assessed using the modified SLE Disease Activity Index. The diagnostic performances of each assay were analyzed using Analyse-it software. Results The diagnostic performances of the total and HA anti-dsDNA EIA kits were comparable to other commercially available in vitro diagnostic assays. Receiver operating characteristic curve analysis demonstrated an area under the curve ranging from 0.85 to 0.89, with the total anti-dsDNA kit demonstrating the highest sensitivity and the HA kit showing higher specificity. An overall agreement of >90% was observed between the total and HA anti-dsDNA EIA kits and commercially available quantitative anti-dsDNA kits. The ratio of HA to total anti-dsDNA antibody was significantly higher among SLE patients with active disease status and/or kidney damage. All assays exhibited a significant correlation with disease activity and multiple clinical manifestations. Conclusions While the clinical performances of various anti-dsDNA assays showed adequate agreements, the BioPlex 2200 anti-dsDNA assay demonstrated the highest positive likelihood ratio and odds ratio. The HA anti-dsDNA EIA kit in association with the total anti-dsDNA kit provided superior performance in SLE diagnosis and monitoring disease activity.

Abstract
Objective: To analyze the clinicopathological features, immunohistochemical (IHC) phentotype,diagnosis and differential diagnosis of infantile/congenital fibrosarcoma (IFS/CFS) with unusual histological features. Methods: Five IFS/CFS at Children's Hospital of Fudan University from March 2014 to July 2018 were analyzed for their diagnosis and differential diagnosis. Results: Two cases were males, three cases were females. The clinical manifestation of IFS/CFS was a rapidly-growing and painless mass. There were no specific radiologic features. Histologically, the tumor cells are arranged in intersecting or sheet-like patterns. There were focal hemangioma-like areas in four cases. There were also focal areas of primitive asteroid, short-spindled, and oval tumor cells in three cases. IHC study showed the tumor cells diffusely expressed TLE1(2/5), Vimentin(5/5), and WT1(3/5), in a cytoplastic pattern; they focally expressed CD34(3/5), CD31(3/5), and α-SMA(2/5). Fluorescence in situ hybridization (FISH) detected break-apart positivity of ETV6 gene. Conclusions: Hemangioma-like pattern, myxoid area, and TLE1 expression is very rare in IFS/CFS. Detection of ETV6 gene break-apart by FISH is very helpful in the diagnosis and differential diagnosis of IFS/CFS.

Abstract
Abstract
BACKGROUND
The drug treatment regimen for glioma has remained relatively static since the introduction of temozolomide, although new drugs and drug combinations are being trialled. The human transcriptome can provide promising insights into causal genes as potential drug interventions for glioma treatment and may guide drug discovery methods.
MATERIAL AND METHODS
We apply two sample Mendelian randomisation and colocalisation to explore the influence of genetically-predicted gene expression across 12 tissue types located in the brain (4,554 genes from GTEx) and whole blood (16,112 genes from eQTLGen) on glioma risk (5,739 cases, 5,501 controls from a meta-analysis of GICC and MDA glioma GWAS). We used the MR-Base R package to conduct these analyses.
RESULTS
We identify 9 genes whose genetically-predicted expression was strongly associated with glioma risk. Of these genes, 7/9 are shown to have tissue-specific expression while the other two genes showed an association with glioma across multiple brain tissues and whole blood. For example, JAK1, involved in the well-known JAK-STAT pathway, is found in the frontal cortex (OR=1.49 for glioma per standard deviation increase in gene expression; 95% CI: 1.28 to 1.73; P=1.79 × 10−7), the cerebellar hemisphere (OR=1.32; 95% CI: 1.19 to 1.47; P=2.64 × 10−7), the cerebellum (OR=1.27; 95% CI: 1.16 to 1.39; P=2.64 × 10−7) and the cortex (OR=1.38; 95% CI: 1.22 to 1.57; P=2.64 × 10−7). This pathway has been highlighted in previous research as a potential intervention target for glioma therapies. We found that 5/9 of the genes from the MR analysis are expressed in the cerebellum. However malignant cerebellar glioma is a rare tumour (~3% of all malignant gliomas). This suggests that tumourigenesis elsewhere in the brain may be affected by other tissue-specific genes, specifically in the cerebellum, though this will require further research to elucidate. We further triangulate the MR findings with evidence from the OpenTargets platform to strengthen the putative causal associations. OpenTargets aims to “generate evidence on the validity of therapeutic targets based on genome-scale experiments and analysis”. For example, JAK1 receives an overall OpenTargets score of 0.89 out of 1, with most of the evidence for this JAK1-glioma association coming from affected pathways data.
CONCLUSION
This study has combined genetic epidemiological approaches to the analysis of the human transcriptome on glioma incidence. We provide evidence that these genes may inform putative drug targets for tertiary treatment of glioma. Future research specifically towards this aim will be required to fully elucidate intervention targets.

Abstract
Tetramethylpyrazine (TMPZ) is one of the active compounds extracted from the traditional Chinese herb Chuanxiong. Several studies have shown its anti-cancer properties. However, its functions in lung cancer and the underlying cellular mechanisms are relatively unknown. Our present study aimed to investigate the effects of TMPZ on A549 and 95D cells. The MTT assay showed that TMPZ decreased cell viability in a dose- and time-dependent manner. The results of the colony formation assay indicated that TMPZ strongly suppressed colony formation ability in A549 and 95D cells. Flow cytometric analysis revealed that TMPZ induced S phase arrest in lung cancer cells. In addition, TMPZ induced apoptosis, as shown by the results of propidium iodide/Annexin V double-staining. Furthermore, TMPZ decreased mitochondrial membrane potential (∆Ψm) in a dose-dependent manner. Finally, western blot analysis of TMPZ-treated cells revealed the activation of Caspase-3 and the increase of the ratio of Bax/Bcl-2. These results demonstrated that TMPZ could suppress carcinogenesis of lung cancer cells through blocking cell cycle and inducing mitochondria-dependent apoptosis by regulating Caspase-3 and Bax/Bcl-2, suggesting that TMPZ may be a promising drug to treat lung cancer.
