Abstract
BACKGROUND Chronic kidney disease (CKD) has become an increasingly important public health disease with a high incidence rate and mortality. Although several studies have explored the effectiveness of resistance exercise in improving the prognosis of CKD patients, the number of studies is still limited and the results are still controversial. OBJECTIVES We conducted this meta-analysis of randomized controlled trials (RCT) studies to evaluate the effectiveness of resistance exercise on CKD patients. METHODS The PubMed, Embase, and Cochrane Library databases were searched from the inception date to October 2023. The meta-analysis was conducted to evaluate 12 main indicators, including glomerular filtration rate (GFR)(ml/(min•1.73m2)), C-reactive protein (CRP) (mg/L), serum creatinine (mg/dL), hemoglobin (g/dL), Glycosylated Hemoglobin, Type A1C (HBA1c) (%), high Density Lipoprotein (HDL) (mg/dL), low Density Lipoprotein (LDL) (mg/dL), 6-min walk(m), body mass index (BMI) (kg/m2), fat-free mass (kg), fat mass (kg), grip strength (kgf). RESULTS Sixteen RCT studies were included in this meta-analysis from 875 records. GFR exhibited no significant change in CKD patients treated with resistance exercise (WMD 1.82; 95%CI -0.59 to 4.23; P = 0.139). However, 6-min walk (WMD 89.93; 95%CI 50.12 to 129.74; P = 0.000), fat-free mass (WMD 6.53; 95%CI 1.14 to 11.93; P = 0.018) and grip strength (WMD 3.97; 95%CI 1.89 to 6.05; P = 0.000) were significantly improved with resistance exercise. The level of CRP (WMD - 2.46; 95%CI -4.21 to -0.72; P = 0.006) and HBA1c (WMD - 0.46; 95%CI -0.63 to -0.29; P = 0.000) dropped significantly after resistance exercise treatment. CONCLUSIONS Resistance exercise can improve physical function, metabolic condition, inflammatory response and cardiopulmonary function in CKD patients, specifically reflected in the increase of indicators fat-free mass, grip strength, 6-min walk, as well as the decrease of indicators HBA1c and CRP.

Abstract
Background Due to the complex histological type and anatomical structures, there has been considerable debate on the classification of adenocarcinoma of the esophagogastric junction (AEG), especially Siewert II AEG. Furthermore, neither the American Joint Committee on Cancer (AJCC) 7th tumor-node-metastasis (TNM) [esophageal adenocarcinoma (E) or gastric cancer (G)] nor the AJCC 8th TNM (E or G) accurately predicted the prognosis of patients with Siewert II AEG. Objective This study aimed to investigate the factors influencing the survival and prognosis of patients with Siewert II AEG and establish a new and better prognostic predictive model. Design A retrospective study. Methods Patients with Siewert II AEG, retrieved from the Surveillance, Epidemiology, and End Results (SEER) databases, were assigned to the training set. Patients retrieved from a single tertiary medical center were assigned to the external validation set. Significant variables were selected using univariate and multivariate Cox regression analyses to construct the nomogram. Nomogram models were assessed using the concordance index (C-index), a calibration plot, decision curve analysis (DCA), and external validation. Results Age, tumor grade, and size, as well as the T, N, and M stages, were included in the nomograms. For the SEER training set, the C-index of the nomogram was 0.683 (0.665-0.701). The C-index of the nomogram for the external validation set was 0.690 (0.653-0.727). The calibration curve showed good agreement between the nomogram estimations and actual observations in both the training and external validation sets. The DCA showed that the nomogram was clinically useful. Conclusion The new predictive model showed significant accuracy in predicting the prognosis of Siewert II AEG.

Abstract
BACKGROUND With the rising prevalence of severe obesity, bariatric surgery has emerged as a crucial treatment option. As the number of surgeries performed worldwide increases, there has been growing interest in the impact of bariatric surgery on cancer incidence. While several studies have examined this relationship, the topic remains controversial. OBJECTIVES We conducted this systematic review of cohort studies with meta-analysis to evaluate the effect of bariatric surgery versus nonsurgical treatment on overall cancer incidence. However, the effects may vary when focusing on specific cancer types, surgical procedures, or gender, so we conducted additional subgroup analyses. SETTING A meta-analysis. University hospital. METHODS The Cochrane, Embase, PubMed, and Web of Science databases were searched for studies from 1 January 2000 to 1 December 2022. Meta-analysis was conducted to evaluate the pooled effect and further implemented subgroup analysis stratified by cancer type, operation type, and sex. RESULTS All cohort studies were included in this meta-analysis from 18,216 studies. The overall cancer incidence demonstrated a significant decrease in the group with bariatric surgery (odds ratios [OR] = .56, P = .000, 95% CI .46 to .68). In subgroup analysis, similar decrease effect was found in 9 cancers. Furthermore, the incidence of cancer decreased significantly in male (OR = .66, P = .001, 95% CI .51 to .85) and female patients (OR = .63, P = .000, 95% CI .57 to .69) and patients undergoing gastric bypass (OR = .46, P = .000, 95% CI .33 to .63) or sleeve gastrectomy (OR = .44, P = .001, 95% CI .27 to .70). CONCLUSIONS In the overall analysis, bariatric surgery could reduce the incidence of cancer significantly. Further large-scale well-matched studies are needed to verify the protective effect of bariatric surgery on cancer incidence.

Abstract
Nucleoside analogues and nucleotide analogues can not only achieve long-term viral suppression in the treatment of most CHB patients but also have a positive impact on other CHB therapeutic goals and an improved prognosis. A certain difference can be observed in the impact of nucleotide analogues such as TDF and TAF and nucleoside analogues such as ETV on the clinical outcomes of CHB. Studies on the mechanism of action indicate that apart from inhibiting the direct antiviral effects of HBV reverse transcriptase, these two categories of drugs exhibit distinct impacts on immune-related signaling pathways, gene expression, genome stability, and other non-antiviral mechanisms. This article reviews the evidence on the potential non-antiviral mechanism of action of nucleoside analogues and nucleotide analogues and proposes a preliminary explanation for the observation trend of nucleotide analogues having a comparative advantage in clinical outcomes in CHB patients based on the latest research advancement.

Abstract
Background Research on the correlation between circulating tumor cells (CTCs) and gastric cancer (GC) has increased rapidly in recent years. However, whether CTCs are associated with GC patient prognosis is highly controversial. Objective This study aims to evaluate the value of CTCs to predict the prognosis of GC patients. Design A meta-analysis. Data Sources and Methods We searched the PubMed, Embase, and Cochrane Library databases for studies that reported the prognostic value of CTCs in GC patients before October 2022. The association between CTCs and overall survival (OS) and disease-free survival (DFS)/recurrence-free survival (RFS) and progression-free survival (PFS) of GC patients was assessed. Subgroup analyses were stratified by sampling times (pre-treatment and post-treatment), detection targets, detection method, treatment method, tumor stage, region, and HR (Hazard Ratio) extraction methods. Sensitivity analysis was performed by removing individual studies to assess the stability of the results. Publication bias was evaluated using funnel plots, Egger's test, and Begg's test. Results We initially screened 2000 studies, of which 28 were available for further analysis, involving 2383 GC patients. The pooled analysis concluded that the detection of CTCs was associated with poor OS (HR = 1.933, 95% CI 1.657-2.256, p < 0.001), DFS/RFS (HR = 3.228, 95% CI 2.475-4.211, p < 0.001), and PFS (HR = 3.272, 95% CI 1.970-5.435, p < 0.001). Furthermore, the subgroup analysis stratified by tumor stage (p < 0.01), HR extraction methods (p < 0.001), detection targets (p < 0.001), detection method (p < 0.001), sampling times (p < 0.001), and treatment method (p < 0.001) all showed that CTC detection was associated with poor OS and DFS/RFS for GC patients. Furthermore, the study showed that CTCs were associated with the poor DFS/RFS of GC when CTCs were detected for patients from Asian or No-Asian regions (p < 0.05). In addition, higher CTCs predicted poorer OS for GC patients who are from Asian regions (p < 0.001), but without statistical difference for GC patients from No-Asian regions (p = 0.490). Conclusion CTC detection in peripheral blood was associated with poor OS, DFS/RFS, and PFS in patients with GC.

Abstract
Catheter-associated urinary tract infection (CAUTI) is one of the common nosocomial infections in burn patients. It not only extends the length of hospital stay of patients, increases the economic burden on family and society, but also seriously affects the prognosis and quality of life of patients, increases the risk of death of patients. In this paper, the epidemiological characteristics, influencing factors, and prevention measures of CAUTI in burn patients are reviewed to draw high attention of clinical medical staff and to provide some reference for clinical practice.

Abstract
BACKGROUND Vagus nerve-preserving gastrectomy is increasingly popular in treating gastric cancer in the early stage, however the long and short-term outcomes after gastrectomy while preserving the celiac branch of the vagus nerve are not well defined. We aimed to summarize and compare perioperative and longer-term outcomes after celiac branch vagus nerve-preserving gastrectomy (CBP, preserving both the celiac and hepatic branches of the vagus nerve), compared to those without CBP (non-CBP, only the hepatic branch of the vagus nerve is preserved). METHODS We searched the Embase, PubMed, Cochrane Library and Web of Science databases for papers published before October 2021. The primary results were evaluated by short-term and long-term postoperative complications, whereas the secondary outcomes included surgery-related parameters, recovery-related parameters and overall survival. Random-effects or fixed-effects model were used to estimate odds ratio, and weighted mean difference for the outcomes. The underlying publication bias was identified via funnel charts, Begg's test and Egger's test. Sensitivity analysis was conducted by removing the research one by one. RESULTS A total of 9 studies consisting of 8 retrospective studies and one randomized control trial were included. The analysis included 1,109 patients, with 568 (51.2%) of patients receiving CBP and 541 (48.8%) patients who received non-CBP. The CBP group had a shorter time in terms of first flatus (weighted mean difference = -0.436, 95% confidence interval: -0.603 to -0.269; P < 0.001) and hospital stay (weighted mean difference = -0.456, 95% confidence interval: -0.874 to -0.037, P = 0.033) than the non-CBP group, but the time to the start of oral intake was comparable between the groups. Regarding short-term complications and surgery-related parameters, between CBP and non-CBP, no evident differences were observed in pancreatic complications, anastomotic leakage, postoperative bleeding, operation time, blood loss or lymph nodes examined. In terms of long-term complications, the incidence of gallstones in CBP was lower than that in non-CBP (odds ratio = 0.582, 95% confidence interval: 0.356-0.953, P = 0.031), and the incidence of bile reflux in CBP was lower than that in non-CBP (odds ratio = 0.473, 95% confidence interval: 0.280-0.800, P = 0.005). However, the prevalence rates of diarrhea, early dumping syndrome, esophageal reflux, and delayed gastric emptying were comparable between CBP and non-CBP. CONCLUSION The present research showed that gastric cancer patients in the early stage under CBP were superior to those without CBP in terms of incidence of gallstones, bile reflux, time of first flatus and hospital stay. Furthermore, it is imperative to conduct randomized control studies with larger sample sizes to determine the oncological survival outcomes when preserving the celiac branch.

Abstract
Ocimum gratissimum (OG) was found to have immunity boosting effect on Taiwan country chickens and broiler chickens raised in moderate ambient temperature in previous studies, and the current study investigates its potential on the growth performance, blood traits, intestinal traits, and immune responses in Ross 308 broilers raised in high ambient temperature which can induce mild heat-stress (26 to 33 ˚C, average 30 ˚C). Two hundred 1-d-old male/female chicks were randomly assigned to a control group, three OG (1 g/kg, 3 g/kg, and 5 g/kg)/basal diet groups, and one Amoxicillin group. Data collected during the experiment indicated that the weight gain increase of 1742 g/bird to 1815 g/bird comparing control to 5 g/kg OG supplementation was statistically significant. In addition, the production efficiency factor was also noticeably increased by OG, particularly in the 5 g/kg group, and the uric acid levels were decreased in the 3 and 5 g/kg OG groups (from 4.26 to 2.91 and 2.90 mg/dL, respectively), indicating heat-stress alleviation was observed. Several areas of the carcass saw desirable growth changes, including the increase of breast muscle ratio observed in the 5 g/kg OG group, an overall decrease in abdominal fat in all OG groups, as well as dimensional changes in several areas of the digestive system. Lastly, the hemaglutination, hemaglutination inhibition, and phytohemaglutinin tests indicated elevated immuno-response in all OG groups. In conclusion, OG has exhibited the ability to alleviate symptoms of mild heat-stress, leading to improvement of the digestive organ development and increase of carcass mass and mean weight gain for birds, and we find OG to be a potentially beneficial feed supplement for poultry raising in high ambient temperature conditions.

Abstract
Objective: To analyze the relationship between infection and transmission of HIV/AIDS, explore the characteristics of the HIV-1 transmission network, and provide evidence for formulating targeted prevention and control measures. Methods: The newly confirmed HIV/AIDS in Jiaxing from 2017 to 2018 were selected for the study. The sociodemographic and infection transmission-related information was gathered. The blood samples were collected and RNA was extracted, RT-PCR and nested PCR amplified the pol gene of HIV-1. The phylogenetic tree was constructed by Mega 6.0 software for subtype analysis. The genetic distance between strains was calculated, and the molecular transmission network was drawn by using Cytoscape 3.6.0 software. The results of the epidemiological study based on the molecular transmission network were analyzed. Results: There were fifteen HIV-1 gene subtypes in 517 cases of HIV/AIDS. The main subtypes were CRF01_AE (37.1%)、CRF07_BC (36.2%) and CRF08_BC (11.8%). Under the 1.0% gene distance threshold, 87 molecular clusters were established, and the total clustering rate was 45.8% (237/517). The cluster risk factors were 60-81 age group (compared with 14-24 age group, OR=2.690, 95%CI:1.058-6.844), married (compared with unmarried, OR=1.698, 95%CI:1.003-2.875), CRF07_BC subtype (compared with CRF01_AE, OR=2.203, 95%CI:1.426-3.404). The largest molecular cluster, CRF07_BC-1, consisted of 50 cases (including 21 cases confirmed in 2017 cases and 29 confirmed in 2018). Multivariate analysis showed that characteristics of unmarried (compared with married, OR=2.482, 95%CI:1.140-5.402), gays (compared with heterosexual, OR=3.163, 95%CI:1.543-6.483), cases with high-risk transmission (compared with other cases, OR=7.631, 95%CI:1.783-32.654), confirmed in Nanhu and Pinghu districts of Jiaxing (compared with other districts, OR=2.225, 95%CI:1.074-4.608) were risks for entering the largest molecular cluster. There were seven suspected high-risk transmission MSM in the largest molecular cluster. The first debut of homosexual behavior was from 2010 to 2018, and the median number of gay partners was 20 (P25, P75:10, 100) within two years before being diagnosed. Six reported a recent history of looking for gay partners in an MSM dating place in Nanhu district. Conclusions: The HIV-1 subtypes of newly confirmed HIV/AIDS were diverse, mainly sporadic in Jiaxing from 2017 to 2018. There were geographical aggregation characteristics and suspected some high-risk transmission cases, suggesting that rapid transmission and targeted intensive intervention are needed.

Abstract
Abstract
Background
Elevated serum lactic acid level is associated with poor outcomes in patients with critical diseases like shock. However, the clinical implication of this biomarker in patients with acute myocardial infarction remains unclear.
Purpose
We aimed to explore the predictive power of serum lactic acid level on admission for in-hospital outcomes in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention (pPCI).
Methods
Consecutive patients undergoing pPCI with available data on serum lactid acid level were evaluated for eligbility in this retrospective cohort study. The primary outcome was all-cause death during hospitalization. Enzymatic infarct size and major adverse cardiovascular events (MACE, defined as a combination of all-cause death, recurrent myocardial infarction, and unplanned repeated revascularization) were considered secondary outcomes. Independent preditors of in-hospital death were determined by multiple logisic regression analysis. Odds ratio (OR) with 95% confidence interval (CI) was used to demonstrate the association. The predictive power of serum latictic acid level for in-hospital death was evaluated through receiver operator characteristic curve, which generated C-statictic. A combination model was further constructed by adding serum latictic acid level to the Global Registry of Acute Coronary Events (GRACE) risk score (LA-GRACE risk score). The linear dependence between serum lactic acids level and othe clinical variables was analysed using Spearman rank correlation.
Results
Of the 302 patients enrolled in the current analysis, 15 (5.0%) died during hospitalization. Serum lactic acid level (OR=1.657, 95% CI: 1.115 to 2.463, p=0.012)and left ventricular ejection fraction (OR=0.858, 95% CI: 0.767 to 0.959, p=0.007) were the only two independent predictors of in-hospital death. The C-statistic of serum lactic acid level for predicting in-hospital death was 0.886 (95% CI: 0.793 to 0.979). The LA-GRACE risk score improved the C-statistic of the GRACE score from 0.898 to 0.911 (p=0.294), with continuous net reclassification improvement of 0.567 (p=0.023) and integrated discrimination improvement of 0.206 (p=0.003). High serum lactic acid level was also asscoiated with larger enzymatic infarct size (p=0.002) and MACE (p=0.004). Further, it significantly correlated with white blood cell counts (r=0.264, p<0.001), serum creatinine level (r=0.189, p=0.001), and systolic blood pressure (r=−0.122, p=0.034).
Conclusion
Serum lactic acid level on admission is asscoiated with poor myocardial perfusion and in-hospital outcomes in patients with acute myocardial infarction undergoing pPCI. It may contribute to better risk stratification in these populations.

Abstract
Objective:This study evaluated the effect of traumatic olfactory nerve injury on drug delivery through the nasal-brain pathway via the instillation of ¹⁸F-FDG at the olfactory cleft. Method:Seven healthy volunteers and 5 patients with traumatic dysosmia were enrolled in the study. Subjects were all instilled with ¹⁸F-FDG on each side of the olfactory cleft under endoscopy. After 12 hours, a PET/MR scan was performed to track the metabolism pathway of ¹⁸F-FDG. Then, we compared the diameter of the olfactory bulb and the olfactory bulb intake between normal volunteers and patients with traumatic olfactory disorders. Result:In healthy volunteers, there was a significant difference in ¹⁸F-FDG uptake between the regions of interest in which ¹⁸F-FDG was or was not in contact with the cribriform plate(P=0.012 7); this difference also existed in patients with traumatic olfactory disorders(P=0.038 1). Patients with traumatic olfactory disorders did not exhibit significant differences in ¹⁸F-FDG uptake in the region of interest compared with healthy volunteers(P=0.937 2). Conclusion:The olfactory bulb is obviously atrophied in patients with traumatic olfactory dysfunction, and the uptake of ¹⁸F-FDG in the olfactory bulb region of interest is also reduced. The administration of ¹⁸F-FDG via olfactory fissure area can enter olfactory bulb and parafrontal tissues through the nasal brain pathway,¹⁸F-FDG can enter the central nervous system through the nasal-brain pathway, which is not affected by olfactory nerve transection injury.

Abstract
The blue-eggshell and dwarf traits have an important economic value in poultry production. Using a genetic aggregation-based strategy, the molecular marker-assisted selection technology was jointly used to provide a rapid breeding method for pure strain chickens simultaneously with hens exhibiting the blue-eggshell and dwarf traits. Overall, 80 male dwarf chickens and 1,000 hybrid blue-eggshell hens (F0) were used for the hybridization experiment. Subsequently, the crossing of F1 or F2 chicks was performed in succession. The F1 and F2 chicks were respectively detected by the joint molecular markers of the solute carrier organic anion transporter family, namely, 1B3 (SLCO1B3) and the growth hormone receptor (GHR) genes, which relate to blue-eggshell and dwarf traits. Meanwhile, the selection of blue-eggshell and dwarf phenotypes was used to validate the data obtained by the molecular markers. The results showed that F1 chicks included the heterozygous and wild-type of SLCO1B3, as well as the homozygous (hens) and heterozygous (roosters) of GHR. However, F2 chicks included 3 different genotypes of both SLCO1B3 and GHR. Ultimately, 196 F1 roosters (concurrently with heterozygous genotype of SLCO1B3 and GHR) and 1,073 F1 hens (concurrently with heterozygous genotype of SLCO1B3 and homozygous genotype of GHR) were obtained from the initial 10,040 F1 chicks. Further, 27 F2 roosters and 345 F2 hens, which simultaneously carried the homozygous genotype of SLCO1B3 and GHR, were screened from the initial 6,000 F2 chicks. Data obtained on the blue-eggshell and dwarf phenotypes were consistent with the results by molecular markers. Similarly, the purity verification of the strain obtained through 2 crossing experiments (F0♂ × F2♀ and F2♂ × F2♀) revealed that all chickens had the blue-eggshell and dwarf traits, supporting that the obtained F2 strain was pure. In summary, for the first time, we successfully bred a pure strain chicken with blue-eggshell and dwarf traits by jointly using the molecular markers of the SLCO1B3 and GHR genes. Our study provides a new method for the rapid cultivation of new chicken strains.

Abstract
UNLABELLED Diagnosis of parathyroid carcinoma on histological examination is challenging. Thousands of differentially expressed lncRNAs were identified on the microarray data between parathyroid cancer and adenoma samples. Four lncRNAs were significantly dysregulated in further validation. The "lncRNA score" calculated from these lncRNAs differentiated parathyroid carcinomas from adenomas. LncRNAs serve as biomarkers for parathyroid cancer diagnosis. INTRODUCTION Diagnosis of parathyroid carcinoma (PC) on histological examination is challenging. LncRNA profile study was conducted to find diagnostic biomarkers for PC. METHODS LncRNA arrays containing 91,007 lncRNAs as well as 29,857 mRNAs were used to assess parathyroid specimen (5 carcinomas and 6 adenomas). Bioinformatics analyses were also conducted to compare the microarray results between parathyroid carcinomas and adenomas (PAs). Differentially expressed lncRNAs of 11 PCs and 31 PAs were validated by real-time quantitative PCR. RESULTS On the microarray data between PC and PA samples (fold change ≥ 2, P < 0.05), 1809 differentially expressed lncRNAs and 1349 mRNAs also were identified. All carcinomas were clustered in the same group by clustering analysis using dysregulated lncRNAs or mRNAs. Four lncRNAs (LINC00959, lnc-FLT3-2:2, lnc-FEZF2-9:2, and lnc-RP11-1035H13.3.1-2:1) identified were significantly dysregulated in further RT-PCR validation. The global "lncRNA score" calculated from the lncRNAs above also differentiated parathyroid carcinomas from adenomas. CONCLUSIONS LncRNA profiling shows distinct differentially expressed lncRNAs in parathyroid neoplasm. They may play a key role in parathyroid cancer and serve as potential biomarkers to distinguish parathyroid cancers from parathyroid adenomas.

Abstract
Objective: To evaluate the safety,efficacy and prognosis of low-temperature plasma radiofrequency coblation for early-stage laryngeal cancer(Tis, T1 and T2). Method: A retrospective analysis of 202 patients with early-stage laryngeal cancer who underwent the low-temperature radiofrequency coblation surgery, including 34 cases of Tis(16.83%), 49 cases of stage T1aN0M0(24.26%), 50 cases of stage T1bN0M0(24.75%) and 69 cases of stage T2N0M0(34.16%). Surgical patients were followed up closely for 6 to 60 months, with a median follow-up of 29 months. Result: Of the 202 patients,165(81.68%) had no recurrence and achieved good surgical results. None of them suffered severe complications such as post-operative hemorrhage and asphyxia. 37 cases(18.32%) had recurrence, including 1 case(0.50%) in stage Tis, 7 cases(3.47%) in stage T1a,7 cases(3.47%) in stage T1b, and 22 cases(10.89%) in stage T2. Thirteen patients who had recurrence underwent total laryngectomy(5 of which had a recurrence of T3 and 8 of which progressed to T4), including 1 in the stage T1a,2 in the stage T1b, and 10 in the stage T2. Vertical hemilaryngectomy were performed in 4 cases, 3 cases of stage T1a and 1 case of stage T2; 5 cases underwent plasma radiofrequency coblation again, including 3 cases of stage T1b and 2 cases of stage T2,no recurrence was found in all the patients; 1 patient had no obvious recurrence in the larynx but had cervical lymph node metastasis, radical neck dissection was performed; 1 patient with stage T2 recurrence was treated with a tracheotomy to relieve laryngeal obstruction without further treatment;3 cases showed improvement by radiotherapy and chemotherapy treatment after recurrence; 9 death cases,5 patients died after radiotherapy and chemotherapy, and 4 patients stopped getting treatment after recurrence.Conclusion: Low-temperature radiofrequency coblation surgery for patients with early-stage laryngeal cancer has great advantages in the preservation of laryngeal function and reduction of surgical trauma after surgery compared with traditional surgical method, and can obtain satisfactory results, but the selection of surgical indications for some patients with clinical stage T2 is still need to be carefully considered..

Abstract
Objective: To investigate the relations of foramen rotundum structure direction and surrounding structure systematically in order to choose the best approach of percutaneous puncturing of radiofrequency thermocoagulation for treating V2 of primary trigeminal neuralgia. Methods: A total of 122 patients with V2 of primary trigeminal neuralgia for radiofrequency thermocoagulation were enrolled from August 2012 to May 2017 at the First Hospital of Jiaxing. CT scan images were observed retrospectively, to find the inside and outside of the foramen rotundum. The direction of foramen rotundum were recorded and the best approach of puncturing were analyzed. Results: The images were divided into four quadrants with the semi - coronal CT scan plane of the lower margin of the zygomatic arch and the outer edge of foramen rotundum for horizontal axis, and the sagittal plane for the vertical axis. In 122 cases, foramen rotundum direction in outer upper quadrant were 77 cases(63.1%), and in outer under quadrant were 22 cases(18.0%), and in inner upper quadrant were 19 cases(15.6%), and in inner under quadrant were 4 cases(3.3%). Conclusion: The most common foramen rotundum direction is in outer upper quadrant, so the best approach of percutaneous puncturing of radiofrequency thermocoagulation for treating V2 of primary trigeminal neuralgia is the upper side against zygomatic and the inner side against the wall of maxillary sinus.

Abstract
Objective:The aim of this study is to investigate the expression of MMP1 and prognosis in patients with head and neck squamous cell carcinoma (HNSCC), and to identify the potential mechanism of MMP1 in HNSCC. Method:The RNA sequencing data and related clinical data of HNSCC were downloaded from the TCGA public database. The MMP1 gene expression data and corresponding clinical information in the samples were retrospectively analyzed; The data of gene microarray were used to verify the correlation between MMP1 gene and HNSCC. The disease free survival and overall survival of HNSCC were also analyzed; Gene set enrichment analysis was conducted to identify the potential mechanism of MMP1 in HNSCC. Result:Among the 332 HNSCC patients, the expression of MMP1 was significantly associated with lymphatic invasion and tumor grade (P<0.01). The higher the expression level of MMP1 was, the more susceptible the patient was to lymph node metastasis. The data confirmed that the expression of MMP1 in HNSCC was significantly higher than that in normal mucosa (P<0.05); HNSCC of patient in MMP1 high expression group proved to have worse disease free survival and overall survival than in MMP1 low expression group (P<0.05); Gene enrichment analysis indicates that the high expression of MMP1 gene might influence the biological process of tumor though epithelial mesenchymal transition, TGF-β signaling pathway, hypoxia, angiogenesis, Noth signaling pathway, and up-regulation of KRAS gene signaling pathway. Conclusion:The high expression of MMP1 was related with occurrence and development of HNSCC, which can be used as an independent risk factor and has a great clinical significance.

Abstract
OBJECTIVE Type 2 diabetes mellitus (T2DM) is a complex polygenic disease that causes hyperglycemia and accounts for 90%-95% of all diabetes mellitus cases. Hence, this study aimed to examine the effects of microRNA-219 (miR-219) on inhibition of long-term potentiation (LTP) and apoptosis of hippocampal neuronal cells in T2DM mice through the N-methyl-d-aspartate receptor (NMDAR) signaling pathway regulation. METHODS The T2DM mouse models were established, after which LTP in vivo was recorded by means of electrical biology, and the fasting blood glucose of mice was measured. Next, the density of pyramidal neurons in each group was calculated. Additionally, the expression levels of miR-219, the NMDAR signaling pathway [NMDAR1 (NR) 1, NR2A, and NR2B), downstream target proteins [calmodulin-dependent protein kinase-II (CaMK-II) and cAMP response element binding protein (CREB)], and apoptosis-related factors [Bcl2-associated X protein (Bax), c-caspase-9 and c-caspase-3] in the hippocampal tissues were determined. Finally, immunohistochemistry was applied to detect and measure the positive expression of Bax, caspase-9, and caspase-3 proteins. RESULTS The results showed that upregulation of miR-219 increases LTP and density of pyramidal neurons in the hippocampal tissues of mice, while it decreases blood glucose of db/db mice. In addition, miR-219 upregulation also leads to decreased mRNA levels of NR1, NR2A, NR2B, CaMK-II, and CREB and protein levels of NR1, NR2A, NR2B, CaMK-II, CREB, p-CREB, Bax, c-caspase-9, and c-caspase-3. Furthermore, upregulation of miR-219 inhibits positive expression of Bax, caspase-9, and caspase-3 proteins, leading to the suppression of hippocampal neuronal cell apoptosis. CONCLUSION The findings from this study indicated that the upregulation of miR-219 decreases LTP inhibition and hippocampal neuronal cell apoptosis in T2DM mice by downregulating the NMDAR signaling pathway, therefore suggesting that MiR-219 might be a future therapeutic strategy for T2DM.

Methods: Total of 143 patients who had 151 breast masses were collected in Fujian Maternity and Children Health Hospital or The Fist Affiliated Hospital of Fujian Medical University from June 2014 to December 2015. Based on pathological results as the gold standard, the diagnostic efficiency of CAD and ultrasonography were compared. Results: The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of ultrasonography were 80.1%, 71.0%, 76.8%, 80.0% and 72.1%, respectively. And the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of CAD were 96.6%, 90.3%, 94.0%, 93.5% and 94.9%, respectively. The specificity, accuracy, positive predictive value and negative predictive of CAD technology were significantly higher than those of ultrasonography (P<0.05). The area under the receiver operator characteristic curve of ultrasonography and CAD were 0.759 and 0.935 respectively, with significant difference (P<0.05). Conclusions: CAD has a higher specificity and accuracy rate than ultrasonography in the diagnosis of breast masses. It could help to differentiate benign from malignant breast masses.

Abstract
The present study provides the first report on the molecular epidemiological data regarding infection by hemoplasma and piroplasma species in wild Rattus edwardsi, from China. In the current study, blood samples were investigated from 32 wild Rattus edwardsi from Hunan (23) and Guangxi (9) provinces, China. The prevalence of hemoplasma and piroplasma was 65.63% (21/32) and 6.25% (2/32), respectively. Phylogenetic analyses indicated that hemoplasmas (HQ183731, HQ183732) derived from wild Rattus edwardsi in China, can be grouped into a solitary clade closely related to H. muris (HMU82963) and M. haemomuris (AB758435). In addition, it was shown that piroplasmas from this study have very close genetic distance to other unidentified piroplasma species isolated from China (AB242140) and Japan (AB188086). The results suggested that hemoplasmas isolated in this study should be represented as a new genotype. Piroplasmas on the other hand needs more sequenced samples in its life-cycle and evidence to check its taxonomic status. These data may have important implications for researching on the epidemiology and population biology as well as for studying the taxonomy status of hemoplasmas and piroplasmids of wild rodents.

Abstract
Direct-acting antiviral agents (DAAs) achieve a high sustained virologic response rate in the treatment of chronic hepatitis C virus infection. However, drug resistance-associated mutations play an important role in treatment failure and have attracted more and more attention. This article elaborates on the clinical significance of drug resistance-associated mutations from the aspects of their definition, association with genotype, known drug resistance-associated mutations and their prevalence rates, the impact of drug resistance-associated mutations on treatment naive and treatment-experienced patients, and the role of clinical detection, in order to provide a reference for clinical regimens with DAAs and help to achieve higher sustained virologic response rates.

Abstract
Directly acting antivirals (DAAs) is a major treatment of hepatitis C virus (HCV) overseas. But DAAs resistance is getting more and more clinicians' attention. DAAs have not been approved in China to date, even though some of them are in clinical trials. However, a good knowledge of DAAs resistance is important on optimizing HCV treatment regimens, increasing sustained virological response (SVR) and decreasing treatment failure in clinical. In this review, DAAs resistance mechanism and virologic barrier to resistance, the prevalence of pre-existing DAAs resistance-associated variants (RAVs), the impact of RAVs on treatment outcome, the options of treatment regimens after resistance and drug resistance testing are discussed, hoping to provide some help for DAAs' standardized treatment in China in the future.

Abstract
OBJECTIVE To investigate the role of glucose-6-phosphate dehydrogenase (G6PD) in hepatitis B virus (HBV) replication and its possible mechanism of action. METHODS Tissue microarray, quantitative real-time PCR, and Western blot were performed to analyze the differences in G6PD expression levels in the HBV-positive and HBV-negative liver tissues, HepG2.2.15 cells, and HepG2 cells. The siRNA transfection technique was used to knock down G6PD gene in HepG2.2.15 cells for 48 hours. Chemiluminescence was used for HBsAg and HBeAg quantification in supernatant, and quantitative real-time PCR was used to measure HBV DNA, type I interferon (IFN), and downstream IFN-stimulated genes. The t-test was used for comparison between groups. RESULTS G6PD expression was significantly upregulated in the HBV-positive liver tissues and cells compared with HBV-negative liver tissues and cells, and the stain intensity and immunohistochemical scores were 89.69±54.92 and 31.90±18.62, respectively (P < 0.05). After G6PD expression in HepG2.2.15 cells was interfered by siRNA, the quantitative levels of HBV DNA, HBsAg, and HBeAg in supernatant were reduced significantly, and the mRNA expression levels of IFNα1, IFNβ1, and five downstream IFN-stimulated genes (OAS1, ISG15, OAS3, EIF2α, and PKR) increased significantly (all P < 0.05). CONCLUSION G6PD plays a vital role in HBV replication, and its mechanism of action in regulating HBV replication may be related to type I IFN signaling pathway.

Abstract
Objective: To investigate the association and interaction of heat shock proteins B1(HSPB1)gene rs2868371 and tumor-suppressor protein p53(TP53)gene rs1042522 polymorphisms with chromosome damage levels among coke oven workers. Methods: We recruited 1 333 male workers from a state-run coke oven plant in Wuhan in September-October 2010. Among them, 949 who had worked in coke oven workplaces, including auxiliary facilities and bottom, side, and top ovens, were nominated as coke oven workers(i.e., exposed), and 384 administrative or medical staff whose workplaces were offices were used as controls. General characteristics and 5 ml of venous blood were collected from each participant. The plasma concentrations of benzo[a]pyrene-diolepoxide(BPDE)-albumin adducts and the lymphocytic micronucleus(MN)frequencies for each individual were detected by ELISA and cytokinesis-block micronucleus assay, respectively. Gene polymorphisms were genotyped using TaqMan assays via quantitative PCR(ABI Prism 7900HT), and the corresponding frequency ratios(FR)with 95% confidence intervals(CI)were computed for all assays. Results: In the exposed group, the MN frequencies were higher in HSPB1 rs2868371 GC, CC, and GC+ CC genotype carriers((3.88 ± 2.88)‰,(4.00 ± 2.66)‰, and(3.91 ± 2.83)‰, respectively)than in rs2868371 GG genotype carriers((3.52±2.67)‰; FR=1.10, 1.13, and 1.11; 95% CI: 1.02-1.19, 1.02-1.25, and 1.03-1.19, respectively), and the HSPB1 rs2868371C allele was associated with increased MN frequency(Ptrend=0.006). Further, in the exposed group, the MN frequencies were lower in TP53 rs1042522 CG and CG+GG genotype carriers((3.63±2.61)‰ and(3.66±2.61)‰, respectively)than in TP53 rs1042522 CC genotype carriers(3.95±3.06)‰(FR=0.87 and 0.90; 95% CI: 0.83-0.96 and 0.84-0.97, respectively). The effect of gene-gene interaction between HSPB1, rs2868371, and TP53 rs1042522 on MN frequency was significant among coke oven workers(P=0.001). Further stratified analyses showed that the effects of the HSPB1 rs2868371C allele in increasing MN frequencies were robust in subjects aged >40 years(FR=1.07, 95% CI: 1.01-1.12), those working >20 years(FR=1.08, 95% CI: 1.02-1.14), those with BMI ≤24 kg/m2(FR=1.07, 95% CI: 1.01-1.13), drinkers(FR=1.09, 95% CI: 1.02-1.16), and workers with higher BPDE-albumin adduct levels(FR=1.07, 95% CI: 1.01-1.13)(Ptrend=0.023, 0.013, 0.029, and 0.020, respectively). The decreasing effect of the TP53 rs1042522 G allele on MN frequencies was robust in subjects aged >40 years(FR=0.94, 95% CI: 0.89-0.99), those with BMI ≤24 kg/m2(FR=0.94, 95% CI: 0.88-0.99), and drinkers(FR=0.94, 95% CI: 0.88-1.00)(Ptrend=0.031, 0.023, and 0.038, respectively). In addition, there were interactions between HSPB1 rs2868371 and age and between HSPB1 rs2868371 and working years in terms of MN frequency(P=0.030 and 0.013, respectively). Conclusion: In coke oven workers, the HSPB1 rs2868371 C and TP53 rs1042522 G alleles were associated with increased and decreased chromosome damage levels, respectively, and their interaction effect on chromosome damage levels was significant.

Abstract
Meriones unguiculatus (Gerbillinae, Rodentia) is widely used as an animal model of human disease. Here, we provide the first report of the complete mitochondrial genome sequence of M. unguiculatus (GenBank accession Nos. KF425526 and NC_023263). The sequence contained the conserved vertebrate pattern of 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and 1 major noncoding region. We identified one extended termination-associated sequence and one conserved sequence block in the non-coding region. The putative origin of replication for the light strand (OL) was 35 bp long. The OL stem and adjacent sequences were highly conserved, but the loop region differed from those of other rodent species. Base composition and codon usage of the 13 protein-coding genes in M. unguiculatus were compared with those of 23 rodent species with previously sequenced mitochondrial genomes. An A+T content of 63.0% was present in M. unguiculatus; this is similar to the Murinae average (62.4 ± 0.8%) and falls between the average for Mus musculus (63.1 ± 0.1%) and Rattus sp (61.7 ± 0.4%). The AT and GC skew values of M. unguiculatus were 0.035 and -0.28, respectively, similar to those of Cricetinae species (0.057 ± 0.05 and -0.31 ± 0.05). The codon families exhibited similar abundance in all 24 species. Analysis of phylogenetic relationships with 23 other rodent species using neighbor-joining and maximum likelihood protocols and the 12 protein-coding regions on the H strand showed that M. unguiculatus should be classified as genus Meriones, sub-family Gerbillinae, family Muridae.

Abstract
The aim of this study was to explore the inhibition of subcutaneously implanted human pituitary tumor cells in nude mice by LRIG1 and its mechanism. For this study, athymic nude mice were injected with either normal pituitary tumor RC-4B/C cells or LRIG1-transfected RC-4B/C cells. We then calculated the volume inhibition rate of the tumors, as well as the apoptosis index of tumor cells and the expression of Ras, Raf, AKt, and ERK mRNA in tumor cells. Tumor cell morphological and structural changes were also observed under electron microscope. Our data showed that subcutaneous tumor growth was slowed or even halted in LRIG1-transfected tumors. The tumor volumes were significantly different between the two groups of mice (χ2 = 2.14, P < 0.05). The tumor apoptosis index was found to be 8.72% in the control group and 39.7% in LRIG1-transfected mice (χ2 = 7.59, P < 0.05). The levels of Ras, Raf, and AKt mRNA in LRIG1-transfected RC-4B/C cells were significantly reduced after transfection (P < 0.01). Transfected subcutaneous tumor cells appeared to be in early or late apoptosis under an electron microscope, while only a few subcutaneous tumor cells appeared to be undergoing apoptosis in the control group. In conclusion, the LRIG1 gene is able to inhibit proliferation and promote apoptosis in subcutaneously implanted human pituitary tumors in nude mice. The mechanism of LRIG1 may involve the inhibition of the PI3K/ Akt and Ras/Raf/ERK signal transduction pathways.

Abstract
OBJECTIVE To study the incidence of positive t(14; 18) and myc gene rearrangement, and the clinical features and prognosis of concurrent positive t(14; 18) and myc gene rearrangement "double-hit lymphoma" (DHL) in diffuse large B cell lymphoma. METHODS The positive t(14; 18) and myc gene rearrangement in 106 cases of DLBCL were analyzed using interphase fluorescent in situ hybridization (FISH) technique. The expression of myc and bcl-2 proteins was determined by immunohistochemistry. The relationship of positive t(14; 18) and myc gene rearrangement with clinical features, pathogenesis and prognosis for the patients was analyzed. SPSS 16.0 software was used for statistical analysis. RESULTS Among the 106 cases, there were 27 (25.5%) cases with positive t(14; 18) and 13 (12.3%) cases with myc gene rearrangement, and 7 cases (6.6%) of DLBCL with concurrent t(14; 18)-positive and myc gene rearrangement. A relationship was observed between positive t(14; 18) and myc gene rearrangement (P=0.019). The follow-up data showed that the 7 DHL patients were in age of 52-84 years, the International Prognostic Index (IPI) scores were 3 in two cases, 4 in four cases and 5 in one case, and the ECOG scores were 3 in all the 7 cases. Four patients had bone marrow involvement and were combined with leukemia. The survival time ranged from 0.5 to 6 months, with a median survival of 4 months. The univariate analysis showed that B symptom, Ann Arbor stage, ECOG score, LDH level, IPI score, immunophenotype, bcl-2 protein expression, myc protein expression, and myc gene rearrangement were all associated with poor prognosis (P<0.05 for all). The multivariate analysis using a COX proportional hazard model confirmed that ECOG score, bcl-2 protein expression, myc protein expression, myc gene rearrangement, and immunophenotype were independent prognostic factors affecting survival (P<0.05 for all), among them, the myc gene rearrangement was the strongest prognostic factor (OR=4.337, P<0.001). CONCLUSIONS "Double-hit" DLBCL is rare and can be mainly identified only by molecular detection. Perhaps positive t(14; 18) and myc gene rearrangement play concurrent role in its "double-hit" pathogenesis. DHL are highly invasive, and most of DHL patients have poor prognosis. Further studies of larger case number are required to determine the pathologic features and the therapeutic strategy of this subgroup.

Abstract
Recently, there has been an upward trend in the occurrence of hand-foot-mouth disease, which is correlated with Coxsackie A6 and A10 infections. Although two separate diagnostic reagents are available for these two viral strains, the protocol and diagnosis efficiency still need to be improved. More importantly, as co-infection with these viruses is common, the development of a single test kit that can diagnose both viruses would be most beneficial for clinical practice. In our study, specific primers targeting viral nucleic acids were designed and modified. Viral nucleic acids were extracted from fecal or throat swab samples by ultrasonic rupture and silicon membrane purification. The consistency, specificity, and sensitivity of the tests were further optimized by adjusting the polymerase chain reaction (PCR) conditions. The efficiency of viral nucleic acid extraction was significantly enhanced by the ultrasonic rupture and silicon membrane elution approach. Specific amplifications of both viral nucleic acids were achieved using modified primers. The optimal conditions for PCR were also determined (60°C for 30 min and 95°C for 2 min, followed by 40 cycles of denaturation for 30 s at 95°C, annealing for 30 s at 60°C, and elongation for 50 s at 72°C). Amplified products were confirmed as viral specific nucleotides by agarose gel electrophoresis and sequencing. The minimal nucleic acid concentration required for detection was 0.2 ng/L, which was adequate to yield satisfactory specificity and consistency. This novel diagnostic method has many advantages, including rapid protocols and accurate results, and can be promoted for large-scale clinical trials.

Abstract
The grey hamster has been used in biomedical research for decades. However, effective molecular methods for evaluating the genetic structure of this species are lacking, which hinders its wider usage. In this study, we employed cross-amplification of microsatellite loci of species within the same genus by polymerase chain reaction. Loci screened included 107 from the Mongolian gerbil (MG) and 60 from the Chinese hamster (CH); of these, 15 polymorphic loci were identified for the grey hamster. Of the 167 loci screened, 95 (56.9%) with clear bands on agarose gel were initially identified. After sequencing, 74 (77.9%) of these matched the criteria for microsatellite characteristics, including 41 from MG and 33 from CH. Lastly, 15 (20.3%) loci with more than two alleles for each locus were identified through capillary electrophoresis scanning. To justify the applicability of the 15 grey hamster loci, genetic indexes of grey hamsters were evaluated using 46 generations of outbred stock, established 20 years ago, from Xinjiang, China. Mean effective allele numbers and expected heterozygosity of stock were as low as, respectively, 1.2 and 0.14; these were 2.8 and 4.0 times inferior, respectively, to wild grey hamsters. This finding suggests that the genetic structure of the stock-bred population is too weak to resist artificial and natural selection, mutation and genetic drifting. In conclusion, we have developed de novo microsatellite markers for genetic analysis of the grey hamster, providing data and methodology for the enrichment of a genetic library for this species.

Abstract
Although gerbils have been widely used in many areas of biological research over many years, there is currently no effective genetic quality control system available. In the present study, we sought to establish a microsatellite marker system for quality control and conducted an optimized analysis of 137 microsatellite loci in two laboratory gerbil populations and one wild population. Independent sample t-tests on the mean effective allele number, mean of Shannon's information index, and mean HE suggested that 28 of the 137 microsatellite markers were informative for gerbil genetic control. Analysis of 4 laboratory gerbil populations and 1 wild population using the 28 microsatellite loci indicated that allele numbers varied from 1.9639 (Guangzhou, GZ) to 6.6071 (North-West wild, NW). The average of HO versus HE was 0.6236/0.3802, 0.6671/0.4159, 0.4185/0.3464, 0.4592/0.3821, and 0.3972/0.4167 for the Beijing, NW, Hangzhou, Dalian, and GZ populations, respectively. The GZ population showed the greatest differentiation, having higher RST and Nei's standard genetic distances. An AMO-VA revealed high genetic differentiation among the five populations (FST = 0.296). The microsatellite system established here is effective and will be important in future studies for genetic quality control and monitoring of gerbil breeds.

Abstract
The catalytic oxidation of CO molecule on a thermodynamically stable Cu4 cluster doped MoS2 monolayer is investigated by density functional theory (DFT) where the reaction proceeds in a new formation order of COOOCO* (O2* + 2CO* → COOOCO*), OCO* (COOOCO* → CO2 + OCO*), and CO2 (OCO* → CO2) desorption with the corresponding reaction barrier values of 0.220 eV, 0.370 eV and 0.119 eV, respectively. Therein, the rate-determining step is the second one. This low barrier indicates high activity of this system where CO oxidation could be realized at room temperature (even lower). As a result, the Cu4 doped MoS2 could be a candidate for CO oxidation with lower cost and higher activity without poisoning and corrosion problems.

Abstract
To optimize the combination of microsatellite loci for genetic control of outbred swine stocks, 32 of 100 loci distributed among almost all chromosomes (except 12) were screened out by 1.5% agarose, 8% polyacrylamide gel and capillary electrophoresis scanning among 3 miniature swine outbred stocks, namely Bama (BM), Guizhou (GZ) and Tibeta (TB). The mean total and effective allele numbers among these stocks were 12.1 and 5.9, respectively. The mean heterozygosity for these breeds was 0.5428, 0.6978 and 0.7646, and polymorphism information content was 0.5469, 0.7296 and 0.7663, respectively. Accordingly, hereditary variation from low to high was BM < GZ < TB. This showed that the genetic relationship between BM and GZ pigs was closer, and both were distant from TB. Additionally, the effectiveness of the 32-locus combination for evaluation of genetic quality was demonstrated in Changchun-junmo-1 (CJ-1), a standard outbred Chinese pig stock, in which the mean total and effective allele numbers and mean heterozygosity were 6.1613, 3.8483 and 0.6903, respectively. Since our results were consistent with the breeding pedigrees, the 32 loci could be used for both genetic monitoring within the individual outbred miniature swine stocks and population structure analysis between them.

Abstract
We optimized a panel of microsatellite markers from cat and tiger genetic data for efficient genetic monitoring and used it to analyze the genetic structure of an outbred cat stock in China. We selected a set of rich polymorphic microsatellite loci from 131 cat microsatellite loci and 3 Sumatran tiger microsatellite loci using agarose gel electrophoresis. Next, the set of optimized genetic markers was used to analyze the genetic variation in an outbred population of orange tabby cats in China by simple-tandem repeat scanning. Thirty-one loci rich in polymorphisms were selected and the highest allele number in a single locus was 8. Analysis of the orange tabby cat population illustrated that the average observed number of alleles, mean effective allele number, mean Shannon's information index, mean expected heterozygosity, and observed heterozygosity were 3.8387, 2.4027, 0.9787, 0.5565, and 0.5528, respectively. The 31 microsatellite markers used were polymorphic and suitable for analyzing the genetic structure of cats. The population of orange tabby cats was confirmed to be a well-outbred stock.

Abstract
Reversion-inducing cysteine-rich protein with kazal motifs (RECK), a
novel tumor suppressor gene that negatively regulates matrix metalloproteinases
(MMPs), is expressed in various normal human tissues but downregulated in several
types of human tumors. The molecular mechanism for this downregulation and its
biological significance in salivary adenoid cystic carcinoma (SACC) are unclear. In
the present study, we investigated the effects of a DNA methyltransferase (DNMT)
inhibitor, 5-aza-2′deoxycytidine (5-aza-dC), on the methylation status of the
RECK gene and tumor invasion in SACC cell lines.
Methylation-specific PCR (MSP), Western blot analysis, and quantitative real-time PCR
were used to investigate the methylation status of the RECK gene and
expression of RECK mRNA and protein in SACC cell lines. The invasive ability of SACC
cells was examined by the Transwell migration assay. Promoter methylation was only
found in the ACC-M cell line. Treatment of ACC-M cells with 5-aza-dC partially
reversed the hypermethylation status of the RECK gene and
significantly enhanced the expression of mRNA and protein, and 5-aza-dC significantly
suppressed ACC-M cell invasive ability. Our findings showed that 5-aza-dC inhibited
cancer cell invasion through the reversal of RECK gene
hypermethylation, which might be a promising chemotherapy approach in SACC
treatment.

Abstract
Beclin 1 plays a critical role in autophagy and functions as a haploinsufficient tumor suppressor. The expression and prognostic significance of beclin 1 in head and neck adenoid cystic carcinoma (ACC) are largely unexplored. Therefore, we investigated the expression of beclin 1, Bcl-2, and p53 in head and neck ACC tissue. Tissue samples from 35 cases (15 females, 20 males) of head and neck ACC were utilized for immunohistochemistry. Beclin 1 expression was observed in 32 cases (91.4%) and considered to be high in 15 cases (42.9%) and low in 20 cases (57.1%). Beclin 1 expression was significantly correlated with a histological growth pattern (P=0.046) and histological grade (P=0.037). Beclin 1 expression was inversely correlated with Bcl-2 expression (P=0.013) and significantly associated with overall survival (P=0.006). Bcl-2 and p53 expression were observed in 21 cases (60.0%) and 16 cases (45.7%). Bcl-2 expression was significantly correlated with perineural invasion (P=0.041) and not associated with overall survival (P=0.053). p53 expression was directly correlated with beclin 1 expression (P=0.044). Our results indicated that beclin 1 may be a novel, promising prognostic factor for clinical outcome in head and neck ACC patients and may play a part in the development of head and neck ACC by interacting with Bcl-2 and p53.

Abstract
Assessment of trace elements such as Cu, Zn, and Se in patients with neurodegenerative disease, such as Alzheimer's (AD) and Parkinson's disease (PD), may be useful in etiologic studies and in assessing the risk of developing these conditions. A prototype point-of-care (POC) instrument based on monochromatic x-ray fluorescence (M-XRF) was assembled and evaluated for the determination of Cu, Zn, and Se in whole blood, plasma, and urine. The prototype instrument was validated using certified reference materials for Cu and Zn in serum/plasma, and the reported bias and relative imprecision were <10%. The M-XRF prototype performance was further assessed using human specimens collected from AD and PD subjects, and was found to be satisfactory (<20% bias) for monitoring Cu and Zn levels in plasma and whole blood. However, the prototype M-XRF sensitivity was not sufficient for quantifying Cu, Zn, or Se in urine. Nonetheless, while validating the prototype instrument, body fluids (whole blood, plasma, and urine) were collected from 19 AD patients, 23 PD patients, and 24 controls specifically for trace element analysis using well-validated methods based on inductively coupled plasma mass spectrometry (ICP-MS). This limited biomonitoring study provided robust data for up to 16 elements including Sb, As, Ba, Cd, Cs, Co, Cr, Cu, Hg, Pb, Mo, Se, Tl, Sn, Zn, and U in plasma, whole blood, and urine. The results did not indicate any significant differences in most trace elements studied between AD or PD patients compared to controls, although the sample size is limited. A statistically significant increase in plasma Se was identified for PD patients relative to AD patients, but this could be due to age differences.

Abstract
A modified technique was developed by electron beam irradiation to prepare tin dioxide (SnO2) nanocrystals using the sol-gel method. SnO2 nanoparticles were radiated under a 1,400 KGy dose. The morphology and microstructure of the SnO2 nanocrystals were investigated by X-ray diffraction, high-resolution transmission electron microscopy (HRTEM), and Raman spectroscopy. The results indicate that the irradiated SnO2 nanoparticles have better crystallinity than unirradiated SnO2 nanoparticles, and the resulting nanocrystals have a tetragonal rutile crystalline structure. The HRTEM image proves that the average grain size is about 4 nm, and the clear lattice fringes indicate the improvement of SnO2 nanocrystals after irradiation. The Raman spectrum shows that there are new peaks at 535 cm(-1) and 691 cm(-1). The optical properties of SnO2 nanoparticles were characterized by ultraviolet-visible (UV-vis) and photoluminescence spectrophotometers. The band gap energy of the irradiated SnO2 was 3.29 eV smaller than that of the unirradiated SnO2 due to size effects and some defects of SnO2 nanocrystals. This work provides a novel approach for the improvement of SnO2 nanocrystals. The optical properties of the irradiated SnO2 nanomaterials are also expected to improve.

Abstract
Fourteen isolates of Toxoplasma gondii were isolated from cats from 4 different geographic provinces (Anhui, Hubei, Shanxi and Guangdong) in China and their genetic diversity with 8 nuclear loci SAG2, SAG3, BTUB, GRA6, L358, PK1, c22-8, c29-2, and an apicoplast locus Apico, was analysed by restriction fragment length polymorphisms (RFLPs). Two genotypes from these 14 isolates were identified but none of them belongs to the typical genetic types (types I, II and III). It is unexpected that such high similarity was observed in these 14 isolates although their original regions are significantly distant. Our results strongly indicate that the three traditional clonal lineages of types I, II and III of this parasite may not be preponderant in China. In addition, our results show that the genotypes of T. gondii in China may be highly clonal with atypical genotypes and higher virulence.

Abstract
It is still controversial whether adjuvant chemotherapy of cisplatin, 5-fluorouracil and leucovorin can increase the overall survival of esophageal cancer patients, and which subgroup of patients get most benefits from it. Between 1998 and 2004, 66 esophageal cancer patients with adjuvant chemotherapy and 160 well-matched patients without chemotherapy were included in this study. Nine markers were measured in the protein level to analyze prognostic significance. In the whole group, adjuvant chemotherapy did not improve the survival of esophageal cancer patients. There was also no significant difference for survival in stage I (P=0.59 and P=0.59), stage II (P=0.28 and P=0.28) and stage III patients (P=0.144 and P=0.06) between the observation and the chemotherapy group. Chemotherapy was most effective for the patients who had metastases in cervical and/or celiac lymph nodes (IV subgroup). One and 3-year disease-free survival and overall survival were significantly better than for those who did not receive the chemotherapy(P=0.038, and 0.016, respectively). Bcl-2 expression was a bad prognostic factor, and was more predictive in the adjuvant chemotherapy group than in the no-chemotherapy group. Adjuvant chemotherapy significantly improved the treatment result of stage IV patients compared with the observation group. Bcl-2 could be used to analyze prognosis and guide the adjuvant treatment.
