Abstract
Objective: To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control. Methods: A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1. The patients in both groups were given oral ribavirin for 48 weeks in addition and then followed up for 24 weeks after drug withdrawal. Abbott Real Time HCV Genotype II was used to determine HCV genotype, and Cobas TaqMan quantitative real-time PCR was used to measure HCV RNA level at 0, 4, 12, 24, 48, and 72 weeks. Adverse events were recorded in detail. The primary efficacy endpoint was sustained virological response (SVR), and a non-inferiority test was also performed. Results: A total of 561 patients with genotype 1/6 CHC were enrolled, among whom 529 received treatment; 90.9% of these patients had genotype 1 CHC. The data of the full analysis set showed that SVR rate was 69.80% (95% CI 65.00%-74.60%) in the trial group and 74.16% (95% CI 67.73%-80.59%) in the control group (P = 0.297 0). The data of the per protocol set (PPS) showed that SVR rate was 80.63% (95% CI 76.04%-85.23%) in the trial group and 81.33% (95% CI 75.10%-87.57%) in the control group (P = 0.849 8), and the 95% CI of rate difference conformed to the non-inferiority standard. The analysis of the PPS population showed that of all subjects, 47.9% achieved rapid virologic response, with a positive predictive value of 93.8%. The incidence rate of adverse events was 96.30% in the trial group and 94.94% in the control group, and the incidence rate of serious adverse events was 5.13% in the trail group and 5.06% in the control group. Conclusion: In the regimen of Peg-IFN-α combined with ribavirin for the treatment of genotype 1/6 CHC, the new investigational drug Peg-IFN-α-2b(Y shape, 40 kD) has comparable clinical effect and safety to the control drug Peg-IFN-α-2a.

Abstract
Pancreatic cancer remains a worldwide issue and burden that is hard to resolve given its low resection rate and chemo-resistance. Early diagnosis and early treatment are critical for conquering pancreatic cancer. Therefore, new biomarkers for diagnosis and prognosis are urgently needed. Previously, researchers mainly focused on protein-coding genetic and epigenetic changes in many types of cancers, and regarded the noncoding part as waste. Recently, however, long non-coding RNA (lncRNA) has emerged as a major participant in carcinogenesis, as it regulates cell proliferation, migration, invasion, metastasis, chemo-resistance, etc. The underlying mechanisms are summarized as signaling, decoy, guide and scaffold, yet the specific regulation networks remain to be uncovered. Several studies have revealed that some lncRNAs are dysregulated in pancreatic cancer, participating in biological functions. In this review, we will briefly outline the functional lncRNAs in pancreatic cancer, decipher possible mechanisms of lncRNAs, and further explore their significance in pancreatic cancer.

Abstract
The external genitalia problems are cumbersome problems for both doctors and parents, as these abnormalities have a consequent impact on future generations. However, the affected young infants are unaware of the consequences due to immature emotional state. Further, the feeling of being different and inferior in affected young patients could give rise to negative emotions including depression, insecurity, anxiety, powerlessness, etc. These all factors collectively could cause a mental imbalance in the affected children. The present review article is focused on the latest updates in the area.

Abstract
Objective: To explore the difference of radiological imaging features of delayed encephalopathy after carbon monoxide poisoning (DECMP) and acute carbon monoxide poisoning (ACMP) , and the correlation between the imaging findings and clinical prognosis of the disease. Methods: The correlation between imaging findings and clinical manifestations and prognosis of 95 patients with moderate and severe acute carbon monoxide poisoning were retrospectively analyzed. In the above 95 cases, there were 62 cases of ACMP and 33 cases of DEACMP. All patients underwent conventional CT, MRI and magnetic resonance diffusion tensor imaging (DTI) . Circular regions of interest (ROI) measurement was used for analysis of average diffusion coefficient (ADC) value and fractional anisotropy (FA) value of the MRI and DTI imaging manifestations in different brain regions. Results: The main clinical manifestation of moderate acute carbon monoxide poisoning was consciousness disorder and fatigue; Severe poisoning patients showed deep coma as the main clinical manifestations; The most prominent clinical manifestations of DEACMP were mental disorders and neurological impairment in the extrapyramidal system. A total of 95 cases with moderate or severe CO poisoning showed unilateral or bilateral cerebral cortex, bilateral basal ganglia (white ball) , cerebral white matter around bilateral ventricles or bilateral centrum semiovale, around bilateral ventricles cerebral white matter around bilateral ventricles and bilateral centrum semiovale, cerebral cortex and subcortical involvement. CT showed normal or low density shadow.MRI showed that the lesion T(1)WI presented slightly low or equal signal, T(2)WI and FLAIR sequences showed equal, a slightly higher or high signal; DWI sequence showed slightly higher or high signal. ADC value and FA value in different brain white matter regions of DEACMP group was significantly lower than those of ACMP group (P<0.05) , especially for those around semi oval center and lateral ventricles of the brain white matter (P<0.01) ; The ADC values increased significantly, FA value decreased significantly in the nerve nucleus (P<0.05) , especially for ADC values in globus pallidus (P<0.01) . Conclusion: DTI can evaluate the brain tissue damage in patients with DEACMP more early and more accurately.

Abstract
Objective: To determine the diagnostic value of serum cystatin C (Cys C) for acute kidney injury (AKI) in patients with liver cirrhosis. Methods: Serum Cys C levels in 150 liver cirrhosis patients (88 AKI and 62 non-AKI patients) were measured by the Particle-Enhanced Nephelometric Immuno-Assay. The accuracy of serum Cys C for the diagnosis of AKI in liver cirrhosis was evaluated by the ROC curve. Results: Liver cirrhosis patients with AKI had significantly higher serum Cys C levels [2.37 (1.75-2.83) mg/L] than those without AKI [0.97 (0.85-1.09) g/L] (P <0.001). Serum Cys C level was highest in the acute tubular necrosis group [5.41 (2.77-6.19) mg/L], followed by the hepatorenal syndrome group [2.55 (2.28-3.59) mg/L] and prerenal azotemia group [2.07 (1.70-2.41) mg/L], and the serum Cys C level was significantly different between the three groups (P <0.001). In addition, patients with AKI were further divided into infection group and non-infection group. Serum Cys C level was significantly higher in the infection group than in the non-infection group (P <0.05). The area under the ROC curve of serum Cys C for the diagnosis of AKI in liver cirrhosis was 0.99 (0.98-1.00) at a cut-off value of 1.36 mg/L, and the sensitivity and specificity were 97% and 95%, respectively. Conclusion: Serum Cys C is a good marker for detecting AKI in liver cirrhosis, and the different levels of increase in Cys C may be useful in differentiating the different types of AKI.

Abstract
OBJECTIVE To investigate the optimal anticoagulation methods and monitoring strategy for Chinese patients undergoing heart valve replacement, which is potentially quite different from western populations. METHODS In this multicenter prospective cohort study, the anticoagulation and monitoring strategy data was acquired from 25 773 in-hospital patients in 35 medical centers and 20 519 patients in outpatient clinic in 11 medical centers from January 1st, 2011 to December 31th, 2015. RESULTS As for in-hospital patients, mean age of study population was (48.6±11.2) years old; main etiology of valve pathology was rheumatic (87.5%) origin among study cohort; 94.8% of study population received mechanical valve implantation; international normalized ratio (INR) monitoring (in all the study centers) and low-intensity anticoagulation strategy (31 hospitals chose target INR range of 1.5-2.5, and actual values of INR among 89.2% of 100 069 in-hospital monitoring samples were 1.5-2.5), with mean actual INR values of 1.84±0.53, and warfarin dosage of (2.82±0.93) mg/d were widely adopted among the study centers; strategies of in-hospital warfarin administration were similar in all the study centers; complication rates of low-intensity anticoagulation strategy were low in severe hemorrhage (0.02%), thrombosis (0.05%), and thromboembolism (0.05%) events, without anticoagulation-related death.As for 18 974 outpatient clinic patients, the follow-up rate was 92.47%, with a total of 30 012 patient-years (Pty). Anticoagulation-related morbidity and mortality rates were 0.67% and 0.15% Pty; major hemorrhage morbidity and mortality rates were 0.25% and 0.13% Pty; thromboembolism morbidity and mortality rates were 0.45% and 0.03% Pty.The mean dosage of warfarin daily dosage was (2.85±1.23) mg/d and INR value was 1.82±0.57.No significant regional difference in the intensity of anticoagulation therapy was noted during the study. CONCLUSIONS INR can be used as a normalized indicator for intensity of anticoagulation therapy in China.The optimal anticoagulation intensity with INR range from 1.5 to 2.5 is safe and effective for Chinese patients with heart valve replacement, and there is no significant regional difference in the intensity of anticoagulation therapy.

Abstract
Peste des petits ruminants (PPR) is an infectious disease caused by peste des petits ruminants virus (PPRV). While PPR mainly affects domestic goats and sheep, it also affects wild ungulates such as ibex, blue sheep, and gazelle, although there are few reports regarding PPRV infection in wild animals. Between January 2015 and February 2015, it was found for the first time that wild ibexes died from PPRV infection in Bazhou, Xinjiang, China, where a total of 38 ibexes (including young and adult ibexes) were found to have died abnormally from PPR-related issues. First, we tested for the presence of the F gene of PPRV by RT-PCR. Then, we compared the sequence of the isolated F gene from the ibex strain, termed PPRV Xinjiang/Ibex/2015, with those previously identified from small domestic ruminants from local areas near where the reported isolate was collected as well as those from other regions. The current sequence was phylogenetically classified as a lineage IV virus, and shared a high level of sequence identity (99.7%) with a previously described Xinjiang PPRV isolate.

Abstract
In cone beam breast computed tomography (CT), scattered radiation leads to nonuniform biasing of CT numbers known as a cupping artifact. Besides being visual distractions, cupping artifacts appear as background nonuniformities, which impair efficient gray scale windowing and pose a problem in threshold based volume visualization/segmentation. To overcome this problem, we have developed a background nonuniformity correction method specifically designed for cone beam breast CT. With this technique, the cupping artifact is modeled as an additive background signal profile in the reconstructed breast images. Due to the largely circularly symmetric shape of a typical breast, the additive background signal profile was also assumed to be circularly symmetric. The radial variation of the background signals was estimated by measuring the spatial variation of adipose tissue signals in front view breast images. To extract adipose tissue signals in an automated manner, a signal sampling scheme in polar coordinates and a background trend fitting algorithm were implemented. The background fits compared with targeted adipose tissue signal value (constant throughout the breast volume) to get an additive correction value for each tissue voxel. To test the accuracy, we applied the technique to cone beam CT images of mastectomy specimens. After correction, the images demonstrated significantly improved signal uniformity in both front and side view slices. The reduction of both intraslice and interslice variations in adipose tissue CT numbers supported our observations.

Abstract
OBJECTIVE The gracilis was once applied in reconstructing erectile function but its appearance was bulky. We aimed to design a model meeting the requirements of both reducing volume and retaining function. MATERIALS AND METHODS The gracilis muscles of 6 rabbits were harvested, applied colorful vascular perfusion and modified Sihler's intramuscular nerve staining. According to their intramuscular nerves and blood vessels, 9 rabbit right gracilis muscles were then longitudinally split into two halves. The anterior muscle bundle was selected as the functional unit and blood supply. RESULTS The intramuscular nerves and vessels were simultaneously presented on a same specimen. Their relationship suggested gracilis muscle to be composed of two relatively independent subunits. The reconstructed penis survived well, simulating erectile action satisfactorily. DISCUSSION The penis model reconstructed with longitudinally split rabbit segmental gracilis myocutaneous flap had met the requirements of both restoring erectile function and improving the appearance.

Abstract
AIMS To compare the prevalence of hepatitis A virus (HAV) and human parvovirus B19 (B19V) between source-plasma (SP) donors and whole blood (WB) donors. BACKGROUND In China, source plasma is in severe shortage while plasma recovered from WB is in surplus. Thus, the government is considering transferring the recovered plasma (RP) to produce plasma derivatives. HAV and B19V are two pathogens threatening the safety of plasma-based derivatives. However, there is no data about if transferring of the RP to produce plasma derivatives will increase the risk of HAV and B19V infection. Thus, we compared the prevalence of HAV and B19V between SP donors and WB donors in this study. METHODS A total of 5030 samples from SP donors and 5040 samples from WB donors were collected. All the samples were tested for HAV RNA and B19V DNA and tested for HAV IgM by enzyme-linked immunosorbent assay (ELISA). RESULTS The prevalence of B19V DNA was 0.06% (95% confidence interval (CI), 0-0.09%) in WB donors and 0.079% (95% CI, 0-0.12%) in SP donors, respectively. No significant difference was found in the prevalence of B19V DNA between SP donors and WB donors. The prevalence of anti-HAV IgM in SP donors was 0.079% whereas no WB donor sample was found anti-HAV IgM reactive. CONCLUSIONS The transfer of RP to producing plasma derivatives will not increase the risk of transmission of HAV and B19 through plasma products.

Abstract
OBJECTIVE Chronic hepatitis B patients with fatty liver disease are gradually increasing. We aim to investigate the serum fragment level of cytokeratin 18 (CK-18), M30 and M65, in chronic hepatitis B (CHB) patients with and non-alcoholic fatty liver disease (NAFLD). PATIENTS AND METHODS Serum M30 and M65 levels were measured by ELISA assay in 46 CHB patients with NAFLD and 42 CHB patients without NAFLD. The association of serum M30 levels in 46 CHB patients with NAFLD and biochemistry and pathological indexes were investigated. RESULTS The serum M30 levels in CHB with NAFLD group were 614.48 ± 471.43 U/L, which were significantly higher than non NAFLD group (374.50 ± 231.04 U/L, p < 0.01). But there were no differences in serum M65 levels between NAFLD group (369.41 ± 262.21 U/L) and non-NAFLD group (296.50 ± 231.44 U/L, p = 0.172). We observed significantly higher serum M30 levels in CHB with NAFLD patients with positive HBV-DNA (752.36 ± 554.79 U/L) as compared with patients with negative HBV-DNA (400.0 ± 171.64 U/L, p < 0.05). While the M65 levels have no significant difference (p = 0.285). For CHB patient with NAFLD patients, the M30 level was positively correlated with ALT, AST, HBVDNA, TG, FBG, histology inflammation score, fibrosis score and steatosis (p < 0.01). CONCLUSIONS Serum M30 levels in CHB with NAFLD patients are significantly higher than CHB patients without NAFLD, especially for HBV-DNA positive patients. It could be a reference value for evaluating the inflammation degree of CHB with NAFLD.

Abstract
The response of a laboratory-raised phytoplankton assemblage to copper and zinc enrichment was studied. Higher intracellular accumulation of both the test metals caused disappearance of metal sensitive species, loss of diversity and species richness, reduced growth rate, Chl a and biovolume; however, the community could recover after 14 days of incubation. Cyanobacteria showed marked sensitivity to both the test metals besides some diatoms, such as, Cyclotella meneghiniana and Melosira granulata. Metal enrichment enhanced the relative abundance of species like Scenedesmus quadricauda, Oocystis borgei, Achnanthes exigua, Fragilaria capucina and Nitzschia amphibia, and these were apparently metal tolerant. Cu and Zn stress induces formation of lipid bodies (bigger in size as well as in number) and morphological abnormalities in diatoms. Among these two metals, Cu impact was higher than Zn despite the fact that the intracellular accumulation of Zn was higher than Cu. Deformed raphe and mixed deformities in diatoms were exclusively found under heavy metal stress which was well supported by regression analysis. Finally the present study gives new insight for using diatoms as an effective tool for biomonitoring and biofuel production.

Abstract
BACKGROUND Oxytocin plays an analgesic role in modulation of nociception and pain. Most work to date has focused on the central mechanisms of oxytocin analgesia, but little is known about whether peripheral mechanisms are also involved. METHODS The mesenteric afferent discharge was recorded in vitro. The expressions of oxytocin receptor (OTR) and neuronal nitric oxide synthase (nNOS) in longitudinal muscle myenteric plexus (LMMP) was identified by immunofluorescence. KEY RESULTS Oxytocin per se had no effect on the jejunal mesenteric afferent discharge, however, it markedly attenuated the bradykinin- or distention-evoked increase of mesenteric afferent discharge, which was mimiced by the nitric oxide (NO) donor sodium nitroprusside (SNP). Pretreatment of either NOS inhibitor L-NAME or NPLA largely reduced the inhibitory effect of oxytocin on bradykinin-evoked mesenteric afferent discharge. Such effect, to a large extent, was also alleviated by N-and P-type voltage-dependent calcium channel antagonists or KATP blocker glibenclamide. In addition, immunofluorescence studies show strong colocalization of OTR with nNOS in LMMP of the rat jejunum. CONCLUSIONS & INFERENCES Oxytocin down-regulates the mesenteric afferent sensitivity through nNOS-NO-KATP pathway. Our findings may reveal a new peripheral mechanism for oxytocin analgesia.
