Abstract
Aim Chronic pancreatitis (CP) is a complex and intractable disease mainly manifested as chronic inflammation and fibrosis. Aspirin(acetylsalicylic acid, ASA) has been reported to be used in the treatment of acute pancreatitis (AP), but its effectiveness on CP is unclear. This study aimed to investigate the therapeutic effects of ASA in CP mice. Methods A murine model of CP was induced by intraperitoneal injection with 20% L-arginine. After one week of L-arginine administration, mice in the ASA treatment group were administered aspirin (100mg/kg/d) by intragastric gavage. At two, four, and six weeks after the first injection of L-arginine, mice were euthanized and the pancreas was collected for histological and molecular analysis. A second model of CP (caeruelin-induced) was used as a validation experiment to test the effect of ASA. Results L-arginine-induced CP resulted in over-expression of the inflammatory enzyme cyclooxygenase (COX)-2. COX-2 expression decreased after ASA treatment. Pancreatic-injury inflammatory response (measured by changes in amylase, CK-19, F4/80, CD3, MCP-1, IL-6) and fibrosis degree (measured by expression of COL1A1, MMP-1 and TIMP-1) was reduce in ASA -treated mice model. The therapeutic effect of ASA was also observed in caeruelin-induced CP. Conclusion ASA has an ameliorating effect in murine models of CP through inhibition of pancreatic inflammation and fibrosis, which may be a promising option for clinical treatment.

Abstract
OBJECTIVE To analyze the effects of high-fat diet on the biological network regulation of gene expression microarray data and key proteins in mouse prostate tissue, and provide some new theoretical evidence for the mechanism of obesity inducing PCa. METHODS From the Gene Expression Omnibus (GEO), we obtained RNAs in the prostate tissue from two groups of C57BL / 6J mice, the normal diet group (n = 5) and high-fat diet group (n = 4). Using the Gene Cloud, Gene-Cloud of Biotechnology Informs (GCBI), GenClip2.0, and Sytoscape 3.5.1, we screened differentially expressed genes, investigated protein interaction networks and biological pathways of differential genes and, from the perspective of transcriptome, explored the effects of high-fat diet on the changes of the molecular network of prostate tissue genes and the molecular biological functions possibly involved. RESULTS A total of 134 differentially expressed genes were identified, 130 up-regulated and 4 down-regulated, mainly involved in biological functions such as chromosome organization, cell-cell signaling, small molecule biosynthesis and leukocyte activation. The Lck, Prkcb and Cd28 genes in the gene network were of high value, indicating an important relationship with protein synthesis and biological functions, the core node of the protein-protein network, and a high predictive ability of Lck and Cd28. CONCLUSIONS The high-fat diet can induce changes in prostate tissue genes, leading to tumorigenesis.

Abstract
Pseudorabies, caused by pseudorabies virus (PRV) variants, has broken out among commercial PRV vaccine-immunized swine herds and resulted in major economic losses to the pig industry in China since late 2011. However, the mechanism of virulence enhancement of variant PRV is currently unclear. Here, a recombinant PRV (rPRV HN1201-EGFP-Luc) with stable expression of enhanced green fluorescent protein (EGFP) and firefly luciferase as a double reporter virus was constructed on the basis of the PRV variant HN1201 through CRISPR/Cas9 gene-editing technology coupled with two sgRNAs. The biological characteristics of the recombinant virus and its lethality to mice were similar to those of the parental strain and displayed a stable viral titre and luciferase activity through 20 passages. Moreover, bioluminescence signals were detected in mice at 12 h after rPRV HN1201-EGFP-Luc infection. Using the double reporter PRV, we also found that 25-hydroxycholesterol had a significant inhibitory effect on PRV both in vivo and in vitro. These results suggested that the double reporter PRV based on PRV variant HN1201 should be an excellent tool for basic virology studies and evaluating antiviral agents.

Abstract
The activation of pancreatic stellate cells (PSCs) plays a critical role in the progression of pancreatic fibrosis. Nuclear factor‐kappa B (NF‐κB) is associated with chronic pancreatitis (CP). Previous evidence indicated that NF‐κB in acinar cells played a double‐edged role upon pancreatic injury, whereas NF‐κB in inflammatory cells promoted the progression of CP. However, the effects of NF‐κB in PSCs have not been studied. In the present study, using two CP models and RNAi strategy of p65 in cultured PSCs, we found that the macrophage infiltration and MCP‐1 expression were increased, and the NF‐κBp65 protein level was elevated. NF‐κBp65 was co‐expressed with PSCs. In vitro, TGF‐β1 induced overexpression of the TGF‐β receptor 1, phosphorylated TGF‐β1–activated kinase 1 (p‐TAK1) and NF‐κB in the PSCs. Moreover, the concentration of MCP‐1 in the supernatant of activated PSCs was elevated. The migration of BMDMs was promoted by the supernatant of activated PSCs. Further knockdown of NF‐κBp65 in PSCs resulted in a decline of BMDM migration, accompanied by a lower production of MCP‐1. These findings indicate that TGF‐β1 can induce the activation of NF‐κB pathway in PSCs by regulating p‐TAK1, and the NF‐κB pathway in PSCs may be a target of chronic inflammation and fibrosis.

Abstract
Objective: Evaluation of the clinical value of the BioPerfectus multiplex real time (BMRT)-HPV for cervical cancer screening. Methods: Physician-collected specimens of 1 495 women who were positive of Cobas 4800 HPV (Cobas-HPV), HPV genotyping based on SEQ uencing (SEQ-HPV), and (or) cytology ≥low grade squamous intraepithelial lesion (LSIL) in the primary screening of Chinese Multiple-center Screening Trial (CHIMUST), and 2 990 women selected from those who were negative of primary screening in the same project through nested control randomization with age-matching were tested for BMRT-HPV, which reported type-specific viral loads/10 000 cells in each specimen. With comparing to Cobas-HPV results and taking cervical histopathological diagnosis as the endpoint, the concordance of high-risk (HR)-HPV subtypes among the three assays was explored ,and the sensitivity and specificity of BMRT-HPV for cervical cancer screening were evaluated. Results: (1) The overall agreenment of HR-HPV subtypes between BMRT-HPV and Cobas-HPV, or SEQ-HPV test sample was 94.8%, 94.4%, with Kappa values 0.827, 0.814. (2) The sensitivity and specificity for cervical intraepithelial neoplasia (CIN) Ⅱ+ of BMRT-HPV, Cobas-HPV and SEQ-HPV were 92.62%, 94.26%, 93.44% and 84.67%, 83.25%, 82.76%, respectively. There were no significant difference in sensitivity among the three HPV assays (all P>0.05), but the specificity of BMRT-HPV for CIN Ⅱ+ was higher than those of Cobas-HPV and SEQ-HPV (P<0.01). The sensitivity for CIN Ⅲ+ of three HPV assays were all 100.00%, and the specificity for CIN Ⅲ+ of BMRT-HPV was higher than those of Cobas-HPV and SEQ-HPV (83.40% vs 81.95%, 83.40% vs 81.50%; P<0.01). The number of pathological examinations of colposcopy for cervical biopsy detected in 1 case of CIN Ⅱ+ or CIN Ⅲ+ in BMRT-HPV was less than those in Cobas-HPV and SEQ-HPV (P<0.01). When using HPV 16/18 + cytology ≥atypical squamous cell of undetermined signification (ASCUS) to triage HPV positive women among three assays, there was no different in the sensitivities of detecting CIN Ⅱ+ and CIN Ⅲ+ (P>0.05). The specificity BMRT-HPV was slightly higher than those in Cobas-HPV or SEQ-HPV (all P<0.05), and the colposcopy referral rate was lower than those in Cobas-HPV and SEQ-HPV (all P<0.05). Conclusions: BMRT-HPV is as sensitive as Cobas-HPV or SEQ-HPV for primary cervical cancer screening, and has higher specificity. Therefore it could be used as a primary screening method for cervical cancer, which is worthy of clinical application.

Abstract
Objective: To investigate the use of p16(INK4a) immuno-stained cytology as the primary screening for cervical cancer prevention. Methods: From March to August 2018, 902 women from Shenzhen and surrounding area were recruited for cervical cancer screening with ThinPrep Cytologic Test (TCT), cobas4800 HPV test, and p16(INK4a) co-test. Colpo/biopsies were performed using the point of interest biopsy protocol of directed and random cervical biopsies plus endocervical curettage for all women, any of whose tests was positive. Two senior cytopathologists interpreted TCT and p16(INK4a) test. The performance of p16(INK4a) for early detection of CIN2+ and inter-observer reproducibility of the interpretation of p16(INK4a) were evaluated. Results: The positive rates of HPV test, p16(INK4a) co-test and TCT diagnosed as LSIL/AGC or higher grade were 8.1% (73/902), 6.8% (61/902) and 4.7% (42/902), respectively. Colposcopy referring rate was 79.6% (109/137), among which 10 cases were diagnosed as CIN2+ (5 cases of CIN2 and 5 cases of CIN3). The sensitivity and specificity for CIN2+ of p16(INK4a) test, TCT (LSIL/AGC or higher grade) and HPV test were 90.0%, 80.0%, 100.0% and 90.9%, 91.9%, 82.5%, respectively. Compared to TCT and HPV test, there was no significant difference in sensitivity and specificity between p16(INK4a) and TCT/HPV test (P>0.05). The Kappa value of the 2 cytopathologists in interpreting p16(INK4a) and TCT was 0.944 and 0.425, respectively (P<0.05). Conclusions: p16(INK4a) for cervical cancer screening is equally sensitive to HPV test and specific to TCT while subjective difference of cytopathologists' interpretation of p16(INK4a) is small. Therefore, p16(INK4a) can be used as a new cervical cancer screen method for its better diagnostic performance.

Abstract
Hepatic fibrosis is a pathophysiological process, which causes excessive extracellular matrix (ECM) deposition resulting from persistent liver damage. Myofibroblasts are the core cells that produce ECM. It is known that epithelial-mesenchymal transition (EMT) is not a simple transition of cells from the epithelial to mesenchymal state. Instead, it is a process, in which epithelial cells temporarily lose cell polarity, transform into interstitial cell-like morphology, and acquire migration ability. Hepatocytes, hepatic stellate cells, and bile duct cells are the types of intrahepatic cells found in the liver. They can be transformed into myofibroblasts via EMT and play important roles in the development of hepatic fibrosis through a maze of regulations involving various pathways. The aim of the present study is to explore the relationship between the relevant regulatory factors and the EMT signaling pathways in the various intrahepatic cells.

Abstract
Objective: To explore the relationship between cervical lesions and high risk HPV (HR-HPV) viral load reflected by the cycle threshold (Ct) values of Cobas 4800 HPV (Cobas 4800) system. Methods: From August 2016 to September 2017, 7 000 women from Shenzhen, were recruited for cervical cancer screening with Cobas 4800 system and cytology co-test. Colposcope biopsies were performed on women who were positive of HPV 16, 18, and positive of HPV types other than 16,18 with cytology [≥ atypical squamous cell of undetermined signification (ASCUS)], or HPV negative but abnormal of cytology [≥ low grade squamous intraepithelial lesion (LSIL)]. The Ct values of HPV 16, 18 and all combined other types coming from Cobas 4800 system were used as an indicator of viral load to analyze the relationship between type-specific HPV load and the cervical lesions. Results: (1) Among the 7 000 screening women, 370 cases were positive for cervical cancer screening, 325 of them underwent colposcope biopsies, and coloposcopy referred rate was 87.8% (325/370). Among 325 women undergoing cervical biopsy, pathological diagnosis was 119 cases of normal cervical cervix, 151 cases of LSIL, and 55 cases of high-grade squamous intraepithelial lesion (HSIL) and above (HSIL(+); including 53 cases of HSIL, 1 case of cervical adenocarcinoma, and 1 case of cervical squamous cell carcinoma). (2) The Ct value of HPV 16 was inversely correlated with the upgrading of the lesions (r=-0.617, P=0.000), and significant different among normal cervix,LSIL and HSIL(+) (35.4±4.5 vs 31.0±6.0 vs 26.5±4.0; F=25.537, P=0.000). There was no correlation between Ct value of HPV 18 and cervical lesions (r=-0.021, P=0.902). The Ct value of other 12 HPV types was statistically difference among normal normal cervix, HSIL(+) and cervicitis (33.0±5.3 vs 29.9±7.2 vs 29.8±5.8; F=5.087, P=0.007). Among them, LSIL and HSIL(+) were significantly lower than normal cervix (P<0.05), but there was no significant difference between LSIL and HSIL(+) (P>0.05). Conclusion: The Ct value of HPV 16 detecting in Cobas 4800 system as an indicator of virus load obviously correlates with different grades of cervical lesions, therefore could be a reference of cervical lesion existence and an indicator of lesion prognosis.

Abstract
OBJECTIVE To analyze the biological network regulation and key proteins of gene expression microarray in human normal prostate epithelial cells after treated with low-dose cadmium, and provide some new theoretical evidence for the pathogenesis of cadmium-related prostate cancer. METHODS We downloaded 19 copies of gene chip data from the Gene Expression Omnibus (GEO), involving 9 samples of prostate epithelial cells exposed to low-dose cadmium and 10 cases of normal control. Using the Gene-Cloud of Biotechnology Informs platform, GenClip2.0 and Sytoscape 3.5.1, we screened differentially expressed genes, explored their protein interaction networks and biological pathways and, from the perspective of transcriptome, analyzed the changes in the genetic network of normal human prostate epithelial cells and their possible molecular biological functions after low-dose cadmium treatment. RESULTS Totally, 1 050 (1.92%) differentially expressed genes were found in the prostate epithelial cells treated with low-dose cadmium, involved in such biological functions as the cell physiological process, MAPK regulation, regulation of intracellular signal transduction, and immunological effect. The HSP90AB1, BUB3 and PRKAR1A genes were the core nodes of the protein network, which showed statistically significant differences in their expressions and a correlation with the malignant transformation of normal cells. CONCLUSIONS Low-dose cadmium can cause genetic changes in normal human prostate epithelial cells and the differentially expressed genes are mainly involved in such biological functions as the cell physiological process, MAPK regulation, regulation of intracellular signal transduction, and immunological effect.

Abstract
Activated pancreatic stellate cells (PSCs) play a crucial role in the progression of pancreatic fibrosis. Transforming growth factor-β (TGF-β) is one of the strongest stimulator inducing fibrosis. The mitogen-activated protein kinase (MAPK) proteins (including ERK, JNK and p38 MAPK) are known to contribute to PSC activation and pancreatic fibrosis. Previous studies have identified PSC activation induced by TGF-β1 is related to MAPK pathway, but the respective role of MAPK family members in PSC activation still unclear, and which family member may be the key mediator in mice PSC activation still controversial. In this study, we investigated the influence of different MAPK family member (JNK, ERK, and p38 MAPK) on mice PSC activation using an in vivo and in vitro model. The results showed p-JNK, p-ERK and p-p38 MAPK were all over-expressed in CP group, and p-JNK, p-ERK, and p-p38 MAPK were co-expressed with activated PSC. In vitro, TGF-β1 induced JNK and ERK over-expression in PSCs. In contrast, p38 MAPK expression in PSC showed only a very weak increase. JNK- and ERK-specific inhibitors inhibited FN and α-SMA mRNA expression in PSCs, and a p38 MAPK inhibitor had no effect on PSC activation. These findings indicate that JNK and ERK were directly involved in the PSCs activation induced by TGF-β1 and the development of pancreatic fibrosis. p38 MAPK participate in the progression of CP, but it does not respond to TGF-β1 directly and may not be regarded as the target of TGF-β1 induced PSC activation.

Abstract
AIM To explore the role of macrophages in chronic pancreatitis (CP) and the effect of Dachaihu decoction (DCHD) on pancreatic fibrosis in mice.
METHODS KunMing mice were randomly divided into a control group, CP group, and DCHD group. In the CP and DCHD groups, mice were intraperitoneally injected with 20% L-arginine (3 g/kg twice 1 d/wk for 6 wk). Mice in the DCHD group were administered DCHD intragastrically at a dose of 14 g/kg/d 1 wk after CP induction. At 2 wk, 4 wk and 6 wk post-modeling, the morphology of the pancreas was observed using hematoxylin and eosin, and Masson staining. Interleukin-6 (IL-6) serum levels were assayed using an enzyme-linked immunosorbent assay. Double immunofluorescence staining was performed to observe the co-expression of F4/80 and IL-6 in the pancreas. Inflammatory factors including monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1α (MIP-1α) and IL-6 were determined using real time-polymerase chain reaction. Western blot analysis was used to detect fibronectin levels in the pancreas.
RESULTS Compared with the control group, mice with 20% L-arginine-induced CP had obvious macrophage infiltration and a higher level of fibrosis. IL-6 serum concentrations were significantly increased. Double immunofluorescence staining showed that IL-6 and F4/80 were co-expressed in the pancreas. With the administration of DCHD, the infiltration of macrophages and degree of fibrosis in the pancreas were significantly attenuated; IL-6, MCP-1 and MIP-1α mRNA, and fibronectin levels were reduced.
CONCLUSION The dominant role of macrophages in the development of CP was mainly related to IL-6 production. DCHD was effective in ameliorating pancreatic fibrosis by inhibiting macrophage infiltration and inflammatory factor secretion in the pancreas.

Abstract
A sensitive and selective high-performance liquid chromatography-electrospray ionisation-tandem mass spectrometry (HPLC-ESI-MS-MS) method for determination of rosiglitazone in human plasma has been developed. After the addition of the internal standard, plasma samples were precipitated by acetonitrile. The compounds were separated on a proC18 column using a mixture of ammonium acetate buffer (0.02 M, pH 6.5) and acetonitrile (in the ratio of 47:53, v/v) as mobile phase. A Finnigan LCQdeca plus ion trap mass spectrometer connected to a Finnigan Surveyor HPLC was used to develop and validate the method. Linearity was established for the range of concentrations 1-1000 ng/ml with a coefficient of determination (r(2)) of 0.999. The intra-day accuracy for rosiglitazone ranged from 110.0 to 99.2% at low, medium and high levels. The inter-day accuracy was less than 15%. The lower limit of quantitation (LLOQ) was identified reproducible at 1.0 ng/ml with a precision of 5.7%. After validation, the method was used to study the pharmacokinetic profile of rosiglitazone in five healthy volunteers after administration of a single oral dose (4.0mg). The proposed method enabled the unambiguous evaluation and quantitation of rosiglitazone for pharmacokinetic, bioavailability or drug-drug interaction studies. A possible chromatography peak (m/z 121, its parent ion m/z 344) of N-demethyl rosiglitazone was observed at 3.49 min during determining rosiglitazone. This may be also a potential method for simultaneous determination of rosiglitazone and its metabolite N-demethyl rosiglitazone concentrations in plasma.

Abstract
BACKGROUND Human cytochrome P450 3A evolved to catalyze the metabolism of numerous common therapy drugs and endogenous molecules. Members of the CYP3A are the majority expressed in human liver and intestine, and there are marked interindividual differences in their protein expression and activity. The activity of CYP3A enzyme in Chinese is highly variable, exceeding 14-fold, and contributes greatly to variation in oral bioavailability and systemic clearance of CYP3A substrates. The genetic factors play an important role in the interindividual variability in CYP3A activity. Detection of CYP3A5 and CYP3A4 variant alleles and knowledge about their allelic frequency in specific ethnic groups are important to lead to individualized drug dosing and improved therapeutics. METHODS We determined the allelic frequency of the CYP3A5*3 and CYP3A4*18 in a group of 302 Chinese subjects by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assays. RESULTS In the group of 302 unrelated individuals, the frequency of the CYP3A5*3 and CYP3A4*18 variant allele in Chinese population were 0.778 (95% CI: 0.754, 0.802) and 0.01 (95% CI: 0, 0.02), respectively. CONCLUSIONS We developed a simple assay for the detection of the CYP3A4*18 allele and showed that in a Chinese population, CYP3A4*18 and CYP3A5*3 allelic frequencies are similar to that reported previously in Chinese resident in Taiwan. The frequency of the CYP3A5*3 allele in Chinese population is similar to the Japanese but lower than Caucasians. Meanwhile, our findings suggest that an approximate 62% of the Chinese population carrying CYP3A5*3/*3 genotype may appear not to express CYP3A5 protein.

Abstract
The effect of body position (right and left lateral position respectively) on gas exchange was observed systematically in 15 patients with unilateral tuberculous pleural effusion. The arterial blood samples were obtained then PaO2 were measured, while the patient lay in the lateral position with normal side down (PaO2-N) for 15 min and with effusion side down (PaO2-E) for 15 min, respectively. The result showed the mean of PaO2-N is significantly higher than that of PaO2-E (P < 0.05). It was postulated that change of PaO2 related to body positions may be attributed to difference in V/Q ratio. Our results may help nurses in managing such patients.
