Abstract
To study the effect of internal particle size on the microstructure properties and thermal decomposition characteristics of site mixed emulsion explosive at different altitudes. Site mixed emulsion explosive was prepared with different shear rate. The particle size, viscosity, sensitized bubbles, detonation velocity and peak pressure of the emulsion explosive were tested after stored at different simulated altitudes. The thermal decomposition characteristics of emulsion matrix prepared at three different rotational speeds were measured by thermogravimetric analyzer and kinetic analysis was performed by non-isothermal model Kissinger-Akah-Sunose (KAS) method. The results show that with the increase in altitude, the internal phase size showed a trend of first increasing and then decreasing, and the number of sensitized bubbles within the emulsion explosive decreases. At an altitude of 0 m, the detonation velocity and peak overpressure of the emulsion explosive prepared by 1600 r min-1 increased 4.78% and 29.09%, respectively compared with 1200 r min-1, and at an altitude of 4500 m, the detonation velocity increased 11.87%, the peak overpressure increased 43.98%. The thermal decomposition activation energy of the emulsion matrix at 1600 r min-1 increased 13.14% compared to 1200 r min-1. It shows that in the production of site mixed emulsion explosive at high altitude, reducing the particle size of the internal phase of emulsion explosives in a certain range can effectively improve the performance of emulsion explosives.

Abstract
Purpose To further clarify the association between abnormal levels of serum lipid components as the main features of dyslipidaemia and hepatocellular carcinoma, which remains unclear. Patients and Methods We examined the serum level of lipids and apolipoproteins pattern in 471 patients undergoing curative resection for HCC, 193 patients with chronic liver disease, and 104 patients with benign liver diseases. We performed uni- and multivariate analyses to evaluate the predictive roles of lipids and apolipoproteins for recurrence and survival of HCC in a training cohort of 242 patients and then validated in a cohort of 229 patients. Results The majority circulating lipid and apolipoprotein levels such as ApoA1, HDL, and LDL in chronic liver disease and HCC were slightly significantly decreased as compared to those in benign lesion. But no significant differential expression patterns of lipids and apolipoproteins were observed between chronic liver hepatitis and HCC. Multivariable analysis identified ApoA1 as a key parameter related to recurrence and survival in both training and validation cohorts. Moreover, we further demonstrated that low ApoA1 was an independent prognostic factor of poor early recurrence in two cohorts. Conclusion Although the alterations of circulating lipids and apolipoproteins were observed in HCC, none of lipids or apolipoproteins could serve as a diagnostic marker. Serum ApoA1 merits consideration as a novel prognostic marker for patients with HCC undergoing surgery since it predicts early recurrence and survival, especially for early stage patients and may improve the prognostic stratification of patients for clinical management and promote HCC clinic outcomes.

Abstract
Objective: To evaluate the effect of renal function on sarcopenia in elderly male patients with chronic kidney disease (CKD). Methods: A total of 105 male CKD patients aged ≥65 years who were admitted to the Chinese PLA General Hospital between October 1, 2018 and January 30, 2019 were included in this study. Using two different equations to estimate glomerular filtration rate (GFR), respectively. According to the sarcopenia criteria, the participants were categorized as the non-sarcopenia group (n=72) and the sarcopenia group (n=33), respectively. The association of estimated GFR (eGFR) and the sarcopenia in the male CKD patients was analyzed using the model of multivariate logistic regression. Results: Among the 105 patients, the median age was 74 (68, 77) years old. The prevalence of sarcopenia was 31.4% (33/105). According to the multivariate logistic regression analysis, eGFR based on serum creatinine and Cys-C (eGFRscr-cys) lower than 45 ml·min(-1)·(1.73 m(2))(-1) (OR=4.17, 95%CI:1.08-16.02, P=0.038) and eGFR based on Cys-C (eGFRcys) lower than 45 ml·min(-1)·(1.73 m(2))(-1) (OR=3.99, 95%CI:1.08-14.75, P=0.038) were independent risk factors for underlying sarcopenic, respectively. The area under the receiver operating characteristics curve (AUC) revealed that eGFRscr-cys (AUC=0.67) was more suitable than eGFRcys (AUC=0.64) to predict the sarcopenia in elderly male patients with CKD. Conclusion: The increased incidence of sarcopenia in elderly men with CKD is accompanied with deterioration of renal function.

Abstract
For biosimilar drug development programs, it is essential to demonstrate that there are no clinically significant differences between the proposed biosimilar therapeutic (biosimilar) and its reference product (originator). Based on a stepwise comprehensive comparability exercise, the biosimilar must demonstrate similarity to the originator in physicochemical characteristics, biological activity, pharmacokinetics, efficacy, and safety, including immunogenicity. The goal of the immunogenicity assessment is to evaluate potential differences between the proposed biosimilar product and the originator product in the incidence and severity of human immune responses. Establishing that there are no clinically meaningful differences in the immune response between the products is a key element in the demonstration of biosimilarity. An issue of practical, regulatory, and financial importance is to establish whether a two-assay (based on the biosimilar and originator respectively) or a one-assay approach (based on the biosimilar) is optimal for the comparative immunogenicity assessment. This paper recommends the use of a single, biosimilar-based assay for assessing immunogenic similarity in support of biosimilar drug development. The development and validation of an ADA assay used for a biosimilar program should include all the assessments recommended for an innovator program (10-16, 29). In addition, specific parameters also need to be evaluated, to gain confidence that the assay can detect antibodies against both the biosimilar and the originator. Specifically, the biosimilar and the originator should be compared in antigenic equivalence, to assess the ability of the biosimilar and the originator to bind in a similar manner to the positive control(s), as well as in the confirmatory assay and drug tolerance experiments. Practical guidance for the development and validation of anti-drug antibody (ADA) assays to assess immunogenicity of a biosimilar in comparison to the originator, using the one-assay approach, are described herein.

Abstract
Objective: To investigate the characteristics of frailty in the elderly male patients with chronic kidney disease (CKD) and the effects of renal function on the incidence of frailty. Methods: A total of 105 non-dialysis CKD patients aged ≥65 years who were admitted to the Chinese PLA General Hospital between October 1, 2018 and January 30, 2019 were included in this study. Their clinical data and laboratory indicators were collected. Frailty was defined according to Fried frailty criteria. According to the frailty scores, the participants were categorized as non-frail (n=37), intermediately frail (n=37) and frail (n=31). The association of frailty and the level of estimated glomerular filtration rate (eGFR) in the patients was analyzed using the model of multivariate Logistic regression. Results: Among the 105 patients, the mean age was 74 (68, 77) years old. The incidence of frail and intermediate frail was 35.2% (37/105) and 29.5% (31/105), respectively. Multivariate logistic analysis showed statistically significant associations of frailty with age (OR=1.14, 95%CI:1.08-1.20, P<0.001), body mass index (OR=0.87, 95%CI:0.79-0.95, P=0.001) and the level of eGFR (OR=0.98, 95%CI:0.96-0.99, P=0.003) in those patients. The incidence of frail in patients with eGFR<45 ml·min(-1)·(1.73 m(2))(-1) and 45-59 ml·min(-1)·(1.73 m(2))(-1) was 1.02 (OR=2.02, 95%CI: 1.06~3.87) and 0.84 (OR=1.84, 95%CI: 1.05-3.22) times higher than that of eGFR≥60 ml·min(-1)·(1.73 m(2))(-1), respectively. Conclusion: The incidence of frailty in the elderly patients with CKD is affected by many factors, such as age, body mass index and renal function, and increases with decreased renal function.

Abstract
BACKGROUND Polyacrylamide hydrogel (PAAG) injections were once common in breast augmentation and have been prohibited for augmentation mammaplasty in China since a large number of patients who underwent breast augmentation with PAAG injections have continued to seek medical advice as a result of related complications. Among all these complications, distant migration is relatively rare.
CASE SUMMARY A 49-year-old female presented at the hospital with a one-year history of a vulvar lump. The sonography of the lump showed several subcutaneous fluid-filled regions from the left vulva to the pubic symphysis, which suggested possible fat liquefaction. An enhanced magnetic resonance imaging (MRI) revealed a cystic area, which was considered a benign lesion. Intraoperative observations showed that the mass did not have an obvious capsule, the subcutaneous tissue presented as a cavity, and some yellow material came out of this cavity. A culture of the drainage did not show bacterial contamination. Histopathology revealed a foreign body granuloma. After resection and closed drainage, lumps were successively observed in the left lower abdomen and the bilateral hypochondriac region with infections. Sonography found that the hypoechoic areas in the bilateral hypochondriac region seemed continuous with deep in the breasts. The patient reported that she had undergone surgery with PAAG injections 20 years ago after she was repeatedly asked about her past history. Finally, a diagnosis of distant migration of PAAG was made.
CONCLUSION PAAG gel can migrate after long periods of time. A diagnosis should not be limited to the area where the symptom develops.

Abstract
BACKGROUND Various inflammation-based prognostic scores have been associated with poor survival in patients with hepatocellular carcinoma (HCC). METHODS Data were collected retrospectively from 674 HCC patients who underwent curative resection. The correlation between INS (inflammation-nutrition score), BCLC (Barcelona Clinic Liver Cancer) stage and inflammatory indices and overall survival (OS) and disease free survival (DFS) was examined. RESULTS An elevated INS was associated with both tumor and host clinical characteristics. The combination of INS and BCLC stage stratifies OS and DFS from 80% and 65% (INS = 0, stage A) to 0% (INS = 2, stage C). Univariate and multivariate analyses revealed that the INS was an independent predictor for OS and DFS, and was superior to inflammation-based scores. In addition, INS was demonstrated to be a prognostic factor for patients with early stage and had a higher AUC value in comparison with inflammation scores. CONCLUSION This study demonstrates that the INS is an independent marker of poor prognosis in patients with resectable HCC, especially for those with early stage, and it provides complimentary prognostic information to BCLC stage, and may aid in treatment strategy.

Abstract
Objective: To assess outcome, safety and possible mechanism of loading dose clopidogrel in patients with transient ischemic attack (TIA) and minor stroke. Methods: We reviewed patients with confirmed TIA and minor stroke admitted between July 2016 and December 2017 into the First Affiliated Hospital of Soochow University. Loss-of-function allele carriers of CYP2C19 were included and randomly divided into loading dose group (first dose of 300 mg clopidogrel) and standard dose group (first dose of 75 mg clopidogrel), 100 mg aspirin was gave at the same time, followed by aspirin 100 mg/d plus clopidogrel 75 mg/d maintaining for 20 days. Platelet aggregation (maximum aggregation ratio, MAR) induced by Adenosine diphosphate (ADP) was examined before and 3 days after administration. The National Institutes of Health Stroke Scale (NIHSS) score method was employed to assess the NIHSS scores before and after treatment in each group of patients; the modified Rankin Scale (mRS) was used to assess the 3-month functional outcome. Results: There was no significant difference in baseline data between the two groups (P>0.05).The proportion of early neurological function improvement in the two groups was 75.0% and 54.8%, and the difference was statistically significant (χ(2)=4.498, P=0.034). The 3-month prognosis was 79.5% and 61.3%, and the difference was statistically significant (χ(2)=4.000, P=0.045). Adverse events: 1 case in the loading dose group, 1 case in the standard dose group, the difference was not statistically significant (2.3% vs 1.6%, χ(2)=0.061, P=0.806). After 3 days of antiplatelet therapy, the MAR of the loading dose group decreased (11%±8%), and the MAR of the standard dose group decreased (9%±4%), the difference was statistically significant (P=0.013).In the loading dose group, there were 32 (72.7%)CYP2C19*2 carriers and 42 (95.5%)CYP2C19*2+*3 carriers; early neurological function improvement in 33 cases, accounting for 93.8% and 76.2%, respectively, and the difference was statistically significant (χ(2)=4.122, P=0.042). There were 35 patients with good prognosis in 3 months, accounting for 96.9% and 81.0%, respectively. The difference was statistically significant (χ(2)=4.310, P=0.038); MAR of CYP2C19*2 carrier was decreased (15%±5%), and MAR of CYP2C19*2+*3 carrier was decreased (12%±8%). The difference was statistically significant (P=0.039). Conclusions: Loading dose clopidogrel can improve the clinical prognosis of minor stroke/TIA without increasing the risk of bleeding. Loading dose clopidogrel may improve the prognosis of minor stroke/TIA by decreasing MAR of CYP2C19*2 carriers.

Abstract
BACKGROUND The differences in treatment outcomes between ultrasound (US)-guided percutaneous microwave ablation (PMWA) and endoscopic thyroidectomy for patients with papillary thyroid microcarcinoma (PTMC) remains unknown. METHODS An electronic search will be performed for randomized controlled trials or observational studies that reported recurrence and mortality rates in PTMC patients with US-guided PMWA or endoscopic thyroidectomy. Hazard ratios with their 95% confidence intervals will be calculated using fixed- or random-effects models according to heterogeneity. RESULTS This study will present the differences in treatment outcomes between US-guided PMWA and endoscopic thyroidectomy for patients with PTMC by pooling the results of individual studies. CONCLUSION The results of this study would provide vigorous evidence in this issue and offer the guidance to both clinical decision-making and future research. ETHICS AND DISSEMINATION Ethical approval is not applicable for this study. PROSPERO REGISTRATION NUMBER CRD42018112320.

Abstract
OBJECTIVE To investigate the clinical characteristics, the medicine application and to evaluate the disease activity in patients with osteoarthritis (OA) in China. METHODS This was a cross-sectional study. Totally 1 066 cases of OA from 40 hospitals in China from April to October 2017 were retrospectively enrolled. Demographic characteristics, clinical data, medicine application, and joint function were evaluated. All the data were analyzed by SPSS software 19.0. t test, Mann-Whitney U test and chi-square test were used for statistical analysis. RESULTS In the 1 066 cases, the male-to-female ratio was 1:3.6 and the average age was (61.9±11.0) years, with an age range from 36 to 94 years. The incidence of knee OA, hip OA, and hand OA were respectively 81.9% (873/1 066), 14.1% (150/1 066), and 36.3% (387/1 066). In the study, 242 (22.7%) cases had two kinds of joint areas involved and three joint areas were involved in 51 cases (4.8%), and 56.6% (603/1 066) of the patients used more than one kind of non-steroid anti-inflammatory drugs (NSAIDs) while 61.2% (652/1 066) used disease modifying osteoarthritis drugs (DMOADs), including glucosamine (37.5%, 400/1 066), chondroitin sulfate (2.0%, 21/1 066), diacetate (5.9%, 63/1 066), and the combination of these drugs (15.8%, 168/1 066). 8.6% (92/1 066) patients only took analgesics to relieve the pain, not using any kind of NSAIDs or DMOADs. And 232 patients (21.7%) had intra-articular injections, including 9.2% (98/1 066) sodium hyaluronate, 4.5%(48/1 066) glucocorticoid, and 8.1% (86/1 066) combination of the two drugs. The proportion of the patients taking topical drugs accounted for 26.5% (283/1 066) and physical therapy accounted for 15.8% (168/1 066). Compared with those who suffered from knee OA, the patients who suffered from hip OA had more severe disease assessment. Moreover, there were significant differences in pain (Z=-7.625, P<0.001), morning stiffness (Z=-6.229, P<0.001), and joint function (Z=-6.777, P<0.001) between the two groups of the patients who suffered from knee or hip OA with The Western Ontario and McMaster Universities (WOMAC) osteoarthritis index. Furthermore, patients with hip OA took more analgesics (χ2=24.838, P<0.001). CONCLUSION Oral NSAIDs and DMOADs are wildly used in patients with OA in China. However, the treatment of some patients still need to be improved. Patients with hip OA are more seriously ill and require aggressive treatment.

Abstract
AIM To retrospectively evaluate the safety and feasibility of a new modified laparoscopic Sugarbaker repair in patients with parastomal hernias.
METHODS A retrospective study was performed to analyze eight patients who underwent parastomal hernia repair between June 2016 and January 2018. All of these patients received modified laparoscopic Sugarbaker hernia repair treatment. This modified technique included an innovative three-point anchoring and complete suturing technique to fix the mesh. All procedures were performed by a skilled hernia surgeon. Demographic data and perioperative outcomes were collected to evaluate the safety and efficacy of this modified technique.
RESULTS Of these eight patients, two had concomitant incisional hernias. All the hernias were repaired by the modified laparoscopic Sugarbaker technique with no conversion to laparotomy. Three patients had in-situ reconstruction of intestinal stoma. The median mesh size was 300 cm2, and the mean operative time was 205.6 min. The mean postoperative hospitalization time was 10.4 d, with a median pain score of 1 (visual analog scale method) at postoperative day 1. Two patients developed postoperative complications. One patient had a pocket of effusion surrounding the biologic mesh, and one patient experienced an infection around the reconstructed stoma. Both patients recovered after conservative management. There was no recurrence during the follow-up period (6-22 mo, average 13 mo).
CONCLUSION The modified laparoscopic Sugarbaker repair could fix the mesh reliably with mild postoperative pain and a low recurrence rate. The technique is safe and feasible for parastomal hernias.

Abstract
Objective: To analyze peripheral blood interleukin-6 (IL-6) promoter DNA methylation status and its clinical significance in patients with systemic lupus erythematosus (SLE). Methods: Blood samples of 41 adult patients with SLE and 20 healthy controls were collected.The methylation status of IL-6 promoter was determined by methylation specific polymerase chain reaction (MSP). The IL-6 expression was detected by real-time PCR.Correlations between IL-6 promoter methylation status and clinical features or laboratory findings in patients with SLE were analyzed. Results: The levels of IL-6 mRNA were significantly higher in peripheral blood of SLE.DNA methylation levels of IL-6 promoter were reduced in SLE patients as compared with healthy controls.The methylation status and expression of IL-6 in peripheral blood reflected the levels in peripheral blood mononuclear cells (PBMCs). Significantly positive correlation was found between IL-6 hypomethylation and renal disorder, as well as hypocomplementemia in patients with SLE. Conclusion: Hypomethylation of interleukin-6 promoter in peripheral blood might be involved in the etiology of SLE.

Abstract
Objective: To explore the status of glucocorticoid application in patients with systemic lupus erythematosus (SLE) in China. Methods: Epidemiological survey was used. The SLE patients who met the 1997 classification criteria of American College of Rheumatology were enrolled. The usage of glucocorticoid and related adverse reactions were recorded and analyzed. Results: A total of 400 SLE patients were enrolled, including 35 men and 365 women. The average age was (37.4±14.0) years old, and the average duration of disease was (6.7±5.8) years. There were 310 patients using glucocorticoid as maintenance. Sixty-one percent (n=244) patients started using medium dose (prednisone 30-<60 mg/d) as the initial treatment of glucocorticoid, which lasted for(37±11)days.The time of drug duration in patients with low dose prednisone (7.5-<30 mg/d)and high dose (60-100 mg/d) was(92±20)and(17±3)days respectively (P<0.05 between 3 groups). However, patients receiving different initial dosage were of no discrepancy in the maintenance therapy. During maintenance, even though 51.0% (n=158) patients were on prednisone 2.5-5 mg/d, the duration of drug use in >5-10 mg/d groupwas longer[(29.9±3.3) months]. Patients with involvement of internal organs had a higher tendency to use 60-100 mg/d prednisone or pulse-dose therapy in the initial treatment, nevertheless these two groups had no difference of maintenance dosage. Among all 400 patients, 62 patients withdrew glucocorticoid, including 17 patients with disease remission (4.3%), 44 by self-withdrawal and one with adverse reaction. Conclusion: In China, the medium dosage of glucocorticoid is the most common initial treatment in patients with SLE.Prednisone 2.5-5 mg/d was the most common choicefor maintenance therapy. Currently, the proportion of glucocorticoid withdrawal remains low in SLE patients achieving remission.

Abstract
Nucleoside triphosphate diphosphohydrolase-1 (ENTPD1/CD39) is the rate-limiting enzyme in a cascade leading to the generation of immunosuppressive adenosine and plays an important role in tumor progression. This study aimed to evaluate the expression of CD39 and CD39Foxp3 regulatory T cells (Tregs) and to determine their prognostic role in patients with hepatocellular carcinoma (HCC) after radical resection.Immunohistochemistry (IHC) and double IHC were used to analyze CD39 expression or the expression of CD39 and Foxp3 in a cohort of 324 HCC patients who underwent curative resection. The quantification of CD39 expression levels was determined using a computerized image analysis system and was evaluated by mean optical density (MOD), which corresponded to the positive staining intensity of CD39. The number of positive Foxp3 cells and both CD39 and Foxp3 positive cells in each 1-mm-diameter cylinder were counted under high-power magnification (×400). The "minimum P value" approach was used to obtain the optimal cutoff value for the best separation between groups of patients in relation to time to recurrence (TTR) or overall survival (OS). The expression of CD39 in HCC cell lines with stepwise metastatic potential and in human umbilical vein endothelial cells was determined by reverse transcription-polymerase chain reaction, Western blotting, and immunofluorescence. The SPSS 17.0 statistical package was used for statistics.CD39 was principally expressed on vascular endothelial cells, macrophagocytes, Tregs, and tumor cells in HCC. Compared with paired peritumoral tissues, tumoral tissues had a significantly higher expression level of CD39 (P < 0.0001). Overexpression of tumoral CD39 was related to increased tumor recurrence and shortened overall survival. Furthermore, the expression level of peritumoral CD39 showed a prognostic role in TTR and OS. Double IHC showed that tumoral tissues had significantly higher Foxp3Tregs and CD39Foxp3Tregs count per 1 mm core (14.1659 vs 4.9877, P = 0.001; 11.5254 vs 3.3930, P < 0.001) and a higher CD39Foxp3/Foxp3 ratio compared with paired peritumoral tissues. CD39Foxp3Tregs were a better prognosticator than CD39Tregs for TTR.Overexpression of CD39 protein in HCC was an independent predictor of poor outcome after radical resection. The CD39Foxp3Tregs count added prognostic power to Foxp3Tregs, providing a potential target for tumor immunotherapy.

Abstract
Ectonucleoside triphosphate diphosphohydrolase 1 (ENTPD1), also known as cluster of differentiation (CD)39, is the rate-limiting enzyme in the generation of immunosuppressive adenosine and is important in tumor progression. The present study evaluated the expression of CD39+ and CD39+ forkhead box P3 (FoxP3)+ regulatory T (Treg) cells in gastric cancer (GC), and determined their prognostic roles in patients with GC following radical resection. It was observed that CD39 was expressed at significantly higher rates in tumor tissues as compared with paired peritumoral tissues. Overexpression of tumor CD39 was correlated with overall survival (OS). Furthermore, CD39 expression in GC tissues exhibited a prognostic role in OS. The CD39+ FoxP3+/FoxP3+ ratio in tumor tissues was higher than that in paired peritumoral tissues, and CD39+ FoxP3+ Treg cells were a better prognostic indicator than FoxP3+ Treg cells for OS. Collectively, our study indicates that overexpression of CD39 in GC is a predictor of poor outcome for GC patients following radical resection. CD39+ FoxP3+ Treg cells are a potential target for cancer immunotherapy.

Abstract
Cotton is one of the most important natural fiber crops in the world. Its growth and yield is greatly limited by drought. A quantitative trait locus (QTL) analysis was therefore conducted to investigate the genetic basis of drought tolerance in cotton (Gossypium spp) using 188 F2:3 lines developed from an inter-specific cross between a wild cotton species, G. tomentosum, and an upland cotton, G. hirsutum (CRI-12). A genetic map was constructed using 1295 simple sequence repeat markers, which amplified 1342 loci, distributed on 26 chromosomes, covering 3328.24 cM. A field experiment was conducted in two consecutive years (2014 and 2015) and 11 morphological and physiological traits were recorded under water-limited (W1)/well-watered (W2) regimes at three growth stages (bud, flowering, and full boll). The traits measured included chlorophyll content, plant height, leaf area, leaf number, leaf fresh weight, leaf dry weight, boll weight, number of bolls per plant, and the number of fruiting branches. Sixty-seven and 35 QTLs were found under the W1 and W2 conditions, respectively. Of these, the majority exhibited partial dominance or over-dominance genetic effects for increasing the trait values. Four consistent QTLs were found under the W1 treatment on chromosomes 5, 8, 9, and 16, whereas no consistent QTL was found in W2. Thirteen QTL clusters were also identified on nine chromosomes (2, 3, 5, 6, 9, 14, 15, 16, and 21). These results will help to elucidate the genetic basis of drought tolerance in cotton.

Abstract
OBJECTIVE To analyze the characteristics of distribution and drug resistance of bacterial infection in several different parts of hematology department inpatients of Anhui Provincial Hospital from January 2010 to December 2014, including patients who had received hematopoietic stem cell transplantation (HSCT). METHODS Anti-microbial susceptibility test was done by Kirby-Bauer method and automated systems and the data were analysed by WHONET 5.6 software. RESULTS A total of 3 312 copies of inspection samples were analyzed, including 2 716 (82%) blood samples and other 596 specimens (18%). 634 bacterial strains were isolated from 3 312 samples (19.14%) including 488 samples (76.97%) from blood culture. 427 (67.35%) bacterial strains were gram-negative, and the other 207 (32.65%) were gram-positive. Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa were most common gram-negative bacterial and the resistant rates to imipenem were 0.8%, 11.8% and 3.3%, respectively. Detection rates of Extended-spectrum beta-lactamases in Escherichia coli and Klebsiella pneumoniae were 83.9% and 75.0%, respectively. At the same time, Coagulase negative Staphylococcus, Streptococcus and Enterococcus were most common kinds of gram-positive bacteria. Methicillin-resistant coagulase negative staphylococcus accounted for 65.9% antibiotic resistance. No vancomycin and/or linezolid and/or tigecycline resistant strains of Staphylococcus spp. and Enterococcus spp. were found in those patients. CONCLUSION Patients with hematology diseases had a higher risk of bacterial infections, mainly caused by Gram-negative bacteria. There are different distributions of bacterial in different wards.

Abstract
As chronic inflammation is involved in the pathogenesis and progression of hepatocellular carcinoma (HCC), we investigated the prognostic accuracy of a cluster of inflammatory scores, including the Glasgow Prognostic Score, modified Glasgow Prognostic Score, platelet to lymphocyte ratio, Prognostic Nutritional Index, Prognostic Index, and a novel Inflammation-Based Score (IBS) integrated preoperative and postoperative neutrophil to lymphocyte ratio in 2 independent cohorts. Further, we aimed to formulate an effective prognostic nomogram for HCC after hepatectomy.Prognostic value of inflammatory scores and Barcelona Clinic Liver Cancer (BCLC) stage were studied in a training cohort of 772 patients with HCC underwent hepatectomy. Independent predictors of survival identified in multivariate analysis were validated in an independent set of 349 patients with an overall similar clinical feature.In both training and validation cohorts, IBS, microscopic vascular invasion, and BCLC stage emerged as independent factors of overall survival (OS) and recurrence-free survival (RFS). The predictive capacity of the IBS in both OS and RFS appeared superior to that of the other inflammatory scores in terms of C-index. Additionally, the formulated nomogram comprised IBS resulted in more accurate prognostic prediction compared with BCLC stage alone.IBS is a novel and validated prognostic indicator of HCC after curative resection, and a robust HCC nomogram including IBS was developed to predict survival for patients after hepatectomy.

Abstract
The aim of this study was to assess the radiographic changes in untreated adults with bilateral anterior disc displacement without reduction. A cohort study was designed to compare the bone changes, effusion, disc configuration, and pseudo-disc changes on two magnetic resonance images obtained at least 24 months apart. Twenty-eight patients (22 female, six male) with a mean age of 33.1 years (range 20-57 years) were included. The mean interval between the initial visit and the follow-up visit was 36.2 months. At the initial visit, the frequencies of bone changes, effusion, disc deformation, and pseudo-disc changes were 51.79%, 35.71%, 100%, and 0%, respectively. At follow-up, the frequency of effusion had decreased significantly. The frequency of bone changes had increased significantly to 75%, but newly formed cortical bone was present in five condyles. All discs remained deformed. Pseudo-disc changes were detected in five joints. Over a long period of observation, there was a significant decrease in effusion and a significant increase in bone changes. However, some adaptive changes occurred.

Abstract
Gossypium tomentosum is a wild allotetraploid species with the (AD)5 genome. It is characterized by many useful traits including finer fiber fineness, drought tolerance, and Fusarium and Verticillium resistance. We constructed the first bacterial artificial chromosome library for Gossypium tomentosum. With high quality and broad coverage, this library includes 200,832 clones, with an average insert size of about 122 kb and fewer than 3% empty clones. Our library is approximately 10-fold the size of the (AD)5-genome (2400 Mb) and provides a 99.7% probability of isolating genes of interest or their sequences. Seven of eight simple sequence repeats markers that are located on five different chromosomes and linked with resistance to Verticillium wilt could amplify the 50 superpools and obtained one to five hits. This high capacity library will be an important genomic resource for classifying and analyzing the evolution of allotetraploid cotton species as well as for isolating disease-resistance and drought-tolerance genes.

Abstract
Simple sequence repeat techniques were used to identify the genetic diversity of 101 Gossypium arboreum accessions collected from India, Vietnam, and the southwest of China (Guizhou, Guangxi, and Yunnan provinces). Twenty-six pairs of SSR primers produced a total of 103 polymorphic loci with an average of 3.96 polymorphic loci per primer. The average of the effective number of alleles, Nei's gene diversity, and Shannon's information index were 0.59, 0.2835, and 0.4361, respectively. The diversity varied among different geographic regions. The result of principal component analysis was consistent with that of unweighted pair group method with arithmetic mean clustering analysis. The 101 G. arboreum accessions were clustered into 2 groups.

Abstract
CD39/ectonucleoside triphosphate diphosphohydrolase-1 (ENTPD1) is a cell surface-located, rate-limiting enzyme in the generation of adenosine, and plays a crucial role in tumor development. We examined co-expression of CD39 and CD8in gastric cancer (GC) and showed that the expression of CD39 and CD8 increased significantly in tumor tissues compared to paired peritumor tissues. The expression of tumoral CD39 (tCD39), but not tumoral CD8 (tCD8), was related to overall survival. Furthermore, the CD39(+)/CD8(+) ratio was associated with poor prognosis in resected GC patients. Taken together, our data indicate that highCD39 expression and high tCD39(+)/CD8(+) ratio in GC is a predictor of poor prognosis for GC patients after radical resection. Moreover, CD39 could serve as a potential target for cancer immunotherapy.

Abstract
We investigated the mechanisms of action of immuno-modulatory drug (lenalidomide) on the protein expression of cereblon (CRBN) and their therapeutic targets in the multiple myeloma cell line RPMI8226. The multiple myeloma cell line RPMI8226 was cultured and treated with different concentrations of lenalidomide and bortezomib to determine the proliferation inhibition rate, apoptosis rate, and protein expression of CRBN. The results revealed that both lenalidomide and bortezomib inhibited the proliferation of RPMI8226 and promoted cell apoptosis. However, the protein expression of CRBN decreased signifi-cantly after treatment with lenalidomide, while bortezomib had no effect on the expression of CRBN. We confirmed that CRBN may be a target of lenalidomide.

Abstract
PURPOSE To investigate the prognostic value of serum amyloid A (SAA) in patients with hepatocellular carcinoma (HCC) undergoing surgery. MATERIALS AND METHODS Preoperative serum samples of 328 patients with HCC who underwent curative resection and of 47 patients with benign liver lesion were assayed. Serum levels of SAA were measured by enzyme-linked immunosorbent assay and its correlations with clinicopathological characteristics and survival were explored. RESULTS Levels of SAA were significantly higher in patients with HCC than those with benign liver lesion. There were strong correlations between preoperative serum SAA level and tumor size and more advanced BCLC stage. On univariate analysis, elevated SAA was associated with reduced disease-free survival and overall survival (p=0.001 and 0.03, respectively). Multivariate analyses showed that serum SAA level was an independent prognostic factor for overall survival (hazard ratio 2.80, p=0.01). CONCLUSIONS High SAA serum level is a novel biomarker for the prognosis of HCC patients.

Abstract
Cotton is an important economic crop worldwide; its fiber, commonly known as cotton lint, is the main natural source for the textile industry. Sixty chloroplast microsatellites were identified and characterized from the complete sequence of the Gossypium hirsutum chloroplast genome using a bioinformatic approach. Twenty chloroplast microsatellite loci were polymorphic in the 66 Gossypium germplasm accessions. A total of 85 alleles were detected, with allele numbers varying from 2-7 per locus. Polymorphism information content varied from 0.02-0.66, with a mean of 0.48. Additionally, transferability of the 20 polymorphic chloroplast microsatellite primers was evaluated in other 31 Gossypium species. Sixteen markers were successfully amplified across all species tested, while the remaining 4 markers cross-amplified in most species tested. These polymorphic chloroplast microsatellite markers may be useful tool for studies of individual identification, genetic diversity, evolution, conservation genetics, and molecular breeding in Gossypium.

Abstract
There is increasing and consistent evidence concerning the association of systemic inflammation and poor outcome in patients with hepatocellular carcinoma (HCC). The aim of this study was to identify a superior inflammation-based prognostic scoring system for patients with HCC undergoing hepatectomy.We analyzed two independent cohorts of a total of 723 patients with HCC who underwent radical surgery between 2010 and 2012. The prognostic value of the inflammation scores, including the Glasgow Prognostic Score (GPS), modified GPS (mGPS), neutrophil-to-lymphocyte ratio, platelet lymphocyte ratio, prognostic index, and prognostic nutritional index, as well as the Barcelona Clinic Liver Cancer and Cancer of the Liver Italian Program staging systems was analyzed in a test cohort of 367 patients and validated in a validation cohort of 356 patients.A high score with the mGPS was associated with large tumor size, vascular invasion, and advanced clinical stage. Multivariate analysis showed that the mGPS was independently associated with overall survival and disease-free survival, and had a higher area under the curve value in comparison with other inflammation-based scores.The results of this study demonstrated that the mGPS is an independent marker of poor prognosis in patients with resectable HCC and is superior to other inflammation-based scores.

Abstract
This study aims to analyze the factors that affect the prognosis of continuous renal replacement therapy (CRRT) in elderly patients with acute kidney injury (AKI). Data obtained from 41 elderly patients with AKI who underwent CRRT in our department between January 2001 and December 2010 was retrospectively evaluated in this study. The enrolled patients were 80 to 100 years old, with a mortality of 60.98%. The mean Acute Physiology and Chronic Health Evaluation II (APACHE II) score was 27.8±5.6 points, and the mean risk coefficient was 0.80±0.10. The APACHE II score of the survival group was significantly higher than that of the death group. The comparisons of therapeutic dosages between <25 mL/(kg⋅h) and 25-50 mL/(kg⋅h), and between 25-50 mL/(kg⋅h) and >50 mL/(kg⋅h) all had no statistical significance. The prognosis of CRRT and the number of involved organs were related to the APACHE II score. Logistic regression analysis revealed that the number of involved organ, APACHE II score, mechanical ventilation, and hypoalbuminemia were the major risk coefficients that affected the prognosis of patients with bedside hemofiltration. The turnover of elderly CRRT patients was related to the number of involved organs, APACHE II score, mechanical ventilation, hypoalbuminemia, and other factors. The APACHE II score was the important reference index of CRRT starting time and could predict mortality risk.

Abstract
OBJECTIVE To explore the feasibility of single-incision laparoscopic totally extraperitoneal hernioplasty (SILS-TEP) with self-made port for repairing of inguinal hernia. METHODS SILS-TEP was performed in 7 inguinal hernia patients (9 sides) with conventional laparoscopic instruments and self-made port, which composed of a wound retractor, surgical gloves and 3 ordinary trocars. The clinical data and follow-up results of 7 cases were retrospectively collected and analyzed. RESULTS The self-made port was applied for SILS-TEP uneventfully without the need of additional ports in all 7 patients (9 inguinal hernias). The median operating time was 90. 0 (70-125) min, intraoperative blood loss was 10. 0 (5. 0-20. 0) mL and postoperative hospital stay was 2.0 (2. 0-4. 0) d. The median pain scores of visual analog scale (VAS) at 6 h,12 h, 24 h and 14 d were 3(2~4), 2(1~2), 1(0~2) and 0(0~1), respectively. There were no intraoperative complications reported, and all patients were satisfied with wound healing. No hernia recurrence was observed during the 3-months of follow-up. CONCLUSION Our initial experiences show that SILS-TEP with self-made port is a safe and feasible surgery, which can simplify the procedure with available equipments and reduce the cost, therefore can be applied in grass-root hospitals.

Abstract
Although the stomach is the most common location for gastrointestinal stromal tumor (GIST) with co-primary tumors, the synchronous appearance of a poorly differentiated neuroendocrine carcinoma (NEC) and GIST in the stomach is extremely rare. To the best of our knowledge, this is the first case of gastric GIST coexisting with gastric NEC to be reported in the literature. The current study reports the case of a 71-year-old male with gastric poorly differentiated NEC and GIST discovered incidentally during surgical treatment of the NEC. Immunohistochemistry analysis showed that the NEC tumor cells were positive for CK (cytokeratin), CD57, synaptophysin, chromogranin, CD117 (KIT protein), Dog-1 (discovered on GIST-1 protein) and CD34. The synchronous GIST immunophenotype showed positivity for CD117, Dog-1 and CD34 (100%), whereas staining for CK, SMA, desmin and S100 was negative. Ki-67 labeling of proliferating cells was 90% in NEC and 1% in GIST. An accurate diagnosis was confirmed by immunohistochemical findings. Furthermore, genetic analysis using PCR direct sequencing identified no mutations in the KIT (exons 9, 11, 13 and 17) and PDGFRA (exons 12 and 18) genes. The patient developed lymph node metastases and underwent cisplatin-based chemotherapy after the operation. This is the first documented case of synchronous gastric GIST and NEC with the examination of protein expression and gene mutations in KIT and PDGFRA, which will help to further understand the etiology and pathogenesis of NEC coexisting with GIST in a gastric location.

Abstract
The aim of this study was to investigate the role of F-18 fluoro-2-deoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) in diagnosis and prognostic evaluation of secondary hemophagocytic syndrome (HPS). A total of 11 secondary HPS patients examined with 18F-FDG-PET/CT were retrospectively analyzed. The diagnostic value of F-18 FDG PET/CT for malignancy detection was assessed. The values of maximum standardized uptake value (SUV(max)) in spleen (SUVS(p)) and in bone marrow (SUVBM) were measured to analyze their relationship with various laboratorial parameters and clinical outcome of secondary HPS patients. The results showed that 4 out of the 11 patients had malignancies, the sensitivity, specificity and diagnostic accuracy of F-18 FDG PET/CT for malignancy detection were 100%, 66.7% and 75% respectively, the SUV(max) of spleen and bone marrow showed no significant correlation with laboratorial parameters, a maximum SUVS(p) of 3.10 and a maximum SUVBM of 3.47 were the optimal cutoffs for predicting patients' outcome, the increased uptake of F-18 FDG in the BM and spleen were significantly associated with shorter survival time according to univariate analysis. It is concluded that 18F-FDG PET/CT may especially play an important role in diagnosis and predicting outcome of secondary HPS for the small sample size.

Abstract
For biosimilar drug development, it is critical to demonstrate similar physiochemical characteristics, efficacy, and safety of the biosimilar product compared to the reference product. Therefore, pharmacokinetic (PK) and immunogenicity (antidrug antibody, ADA) assays that allow for the demonstration of biosimilarity are critical. Under the auspices of the American Association of Pharmaceutical Scientists (AAPS) Ligand-Binding Assay Bioanalytical Focus Group (LBABFG), a Biosimilars Action Program Committee (APC) was formed in 2011. The goals of this Biosimilars APC were to provide a forum for in-depth discussions on issues surrounding the development and validation of PK and immunogenicity assays in support of biosimilar drug development and to make recommendations thereof. The Biosimilars APC's recommendations for the development and validation of ligand-binding assays (LBAs) to support the PK assessments for biosimilar drug development are presented here. Analytical recommendations for the development and validation of LBAs to support immunogenicity assessments will be the subject of a separate white paper.

Abstract
Although human umbilical cord mesenchymal stem cells (hUC-MSCs) have been identified as a new source of MSCs for potential application in regenerative medicine, their full potential of differentiation has not been determined. In particular, whether they have the capability to differentiate into epithelial cells of endodermal origin such as the prostate epithelial cells is unknown. Here we report that when hUC-MSCs were combined with rat urogenital sinus stromal cells (rUGSSs) and transplanted into the renal capsule in vivo, they could differentiate into prostate epithelial-like cells that could be verified by prostate epithelial cell-specific markers including the prostate specific antigen. The prostatic glandular structures formed in vivo displayed similar cellular architecture with lumens and branching features as seen for a normal prostate. In addition, the human origin of the hUC-MSCs was confirmed by immunocytochemistry for human nuclear antigen. These findings together indicate that hUC-MSCs have the capability to differentiate into epithelial-like cells that are normally derived from the endoderm, implicating their potential applications in tissue repair and regeneration of many endoderm-derived internal organs.

Abstract
Background Sirtuin 3 (Sirt3), one of the seven Sirtuins family members, plays critical roles in the progression of multiple cancer types. However, its role in the prognosis of hepatocellular carcinoma (HCC) has not yet been investigated systematically. Methods The correlation of Sirtuins expression with prognosis of HCC was determined by immunohistochemistry (IHC) in a large HCC patient cohort (n = 342). Expression of Sirt3 in tumoral and peritumoral tissues of HCC patients were further determined by western blotting (WB). Results IHC and WB studies both showed a decreased expression of Sirt3 in tumoral tissues compared with peritumoral tissues (P = 0.003 for IHC, P = 0.0042 for WB). Decreased expression of Sirt3 in both tumoral and peritumoral tissues was associated with increased recurrence probability and decreased overall survival rate by univariate analyses (intratumoral Sirt3: P = 0.011 for TTR, P = 0.001 for OS; peritumoral Sirt3: P = 0.017 for TTR, P = 0.023 for OS), the prognostic value was strengthened by multivariate analyses (intratumoral Sirt3: P = 0.031 for TTR, P = 0.001 for OS; peritumoral Sirt3: P = 0.047 for TTR, P = 0.031 for OS). Intratumoral Sirt3 also showed a favorable prognostic value in patients with BCLC stage A (TTR, P = 0.011; OS, P < 0.001). In addition, we found that IHC studies of other sirtuin members showed a decreased expression of Sirt2, Sirt4 and Sirt5 and an increased expression of Sirt1, Sirt6 and Sirt7 in intratumoral tissues compared with peritumoral tissues. In contrast to Sirt3, other members did not showed a remarkable correlation with HCC prognosis. Conclusions Down-regulation of intratumoral and peritumoral Sirt3 were both associated with poor outcome in HCC, moreover, intratumoral Sirt3 was a favorable prognostic predictor in early stage patients.

Abstract
BACKGROUND Matrix metalloproteinases (MMPs) are supposed to be potential drug targets to prevent leakage after colonic anastomosis. A method of colonic anastomosis by using a stent coated with doxycycline, a MMP inhibitor, was developed and its safety and feasibility, as well as the effect of locally regulating MMPs, were evaluated by comparing with the conventional method or the method with a doxycycline-free stent. METHODS 48 pigs were assigned randomly to doxycycline-coated stent anastomosis group (DSA), doxycycline-free stent anastomosis group (SA), or conventional anastomosis group (CA). In each group, pigs were subdivided into four subgroups according to postoperative observation time (3, 7, 14, and 30 days). Healing of anastomosis and expressions of MMP-2/9 were evaluated. RESULTS No anastomotic leakage, stricture or necrosis was observed in the DSA group. No significant difference of bursting pressure was found between the DSA group and SA group. Relative expression of MMP-2 in the DSA group was significantly lower than in the SA group on postoperative days 3 and 7. No significant differences of hydroxyproline content, microvessel density and TGF-β1 level were found in these groups. CONCLUSION These results suggested this method was feasible and safe for colonic anastomosis with the advantage of locally inhibiting MMPs.

Abstract
The cytotoxicities of two oxovanadium complexes, VOI [VO(satsc)(phen)] (satsc = salicylaldehyde thiosemicarbazone, phen = 1,10-phenanthroline) and VOII [VO(3,5-dibrsatsc)(phen)](3,5-dibrsatsc = 3,5-dibromosalicylaldehyde thiosemicarbazone), were studied by performing MTT assays on human hepatoma cell lines BEL-7402, HUH-7 and HepG2. The results showed that both the VOI and VOII complexes possess significant anti-proliferative effects. In addition, the anti-proliferative mechanism of the complexes was analyzed by cell cycle analysis and an apoptosis assay and by detecting the mitochondrial membrane potential (delta psi m). The experimental results showed that the complexes can cause a G0/G1 phase cell cycle arrest and can significantly decrease delta psi m, causing depolarization of the mitochondrial membrane. Notably, the two complexes induced apoptosis in BEL-7402 cells and displayed typical morphological apoptotic characteristics. The cytotoxicities of the VOII complex are significantly stronger than that of the VOI complex, suggesting that the cytotoxic effects of oxovanadium complexes may be associated with the electronic effects of the complexes.

Abstract
Regulatory T cells (Treg) play a vital role in immunosuppressive crosstalk; however, Tregs from different locations lead to different clinical outcomes. Our aim was, therefore, to compare the prevalences and suppressive phenotypes of Tregs in the peripheral blood, peritumor, and intratumor of patients with hepatocellular carcinoma (HCC). METHODS : The frequencies and phenotypes of CD4(+) CD25(+) CD127(low/-) CD49d(-) Tregs in the periphery, peritumor, and intratumor of 78 HCC patients and 12 healthy controls were evaluated by flow cytometry. Treg-cell suppressive activity was determined using an in vitro CD154 expression assay. Tregs from tumor and paired peritumor were then hybridized using an Agilent whole genome oligo microarray, and selected genes were validated by real-time polymerase chain reaction. Functional analysis of the microarray data was performed using Kyoto Encyclopedia of Genes and Genomes and Gene Ontology analyses. RESULTS : Intratumoral Tregs exhibited higher frequencies and more suppressive phenotypic functions than those in peritumor and periphery, whereas there was no difference between the latter two. Functional analysis showed that complement cascades, p53, and glycosylphosphatidylinositol-anchor biosynthesis pathways were significantly upregulated in intratumoral Tregs; the salivary secretion pathway was significantly downregulated in intratumoral Tregs, and immune cells and tumor-immuno-related Gene Ontology terms were significantly affected. CONCLUSIONS : Tregs in different locations exhibited different functional statuses. A higher prevalence and more suppressive phenotype suggested a critical role for intratumoral Tregs in the formation of multicellular immunosuppressive networks. HCC immunotherapy may be improved, therefore, by specific locational Tregs elimination or suppression.

Abstract
BACKGROUND & AIMS The immunosuppressive network within the tumor microenvironment is one of the major obstacles to the success of cancer immunotherapy. γδ T cells are attractive effectors for cancer immunotherapy. Nevertheless, the promising anti-tumor effect in vitro is partially if not totally mitigated in vivo. Thus, understanding the immune status of tumor-infiltrating γδ T cells is essential for orchestrating effective immunotherapy strategies. In this study, we have investigated the immunophenotype and function of γδ T cells in hepatocellular carcinoma (HCC) patients. METHODS The phenotype of γδ T cells in peripheral blood, and peritumoral and tumoral tissues of HCC patients (n=61) was characterized by flow cytometry. Functional analysis of the HCC-infiltrating γδ T cells was conducted directly after γδ T cell isolation. RESULTS The infiltration of γδ T cells in tumoral tissues was significantly reduced compared to paired peritumoral tissues. Impairment in degranulation of the granule pathway and downregulation of IFN-γ secretion were also demonstrated in HCC-infiltrating γδ T cells, which was in agreement with the results of gene microarray analysis, and further strengthened by the compromised specific cytotoxicity and IFN-γ secretion in vitro. Moreover, isolated HCC-infiltrating CD4(+)CD25(+) regulatory T cells (Treg cells) directly suppressed the cytotoxic function and IFN-γ secretion of γδ T cells in a TGFβ- and IL-10-dependent manner. CONCLUSIONS The effector function of γδ T cells was substantially impaired in HCC, which is partially mediated by Treg cells. We propose a new mechanism by which immune privilege develops within the tumor milieu.

Abstract
AIM: To assess the outcomes of ampulla dilation with different sized balloons to remove common bile duct (CBD) stones.
METHODS: Patients (n = 208) were divided into five groups based on the largest CBD stone size of < 5, 6-8, 8-12, 12-14, and > 14 mm. Patients underwent limited endoscopic sphincterotomy (EST) alone or limited EST followed by endoscopic papillary balloon dilation with 8, 10, 12 and 14 mm balloons, such that the size of each balloon did not exceed the size of the CBD. Short- and long-term outcomes, such as post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, perforation, bleeding, and pneumobilia were compared among the five groups.
RESULTS: The overall rate of successful stone removal in all groups was 100%, and all patients were cured. Eight (3.85%) patients had post-ERCP pancreatitis, none had perforations, and 6 (2.9%) had bleeding requiring transfusion. There were no significant differences in early complication rates among the five groups. We observed significant correlations between increased balloon size and the short- and long-term rates of post-ERCP pneumobilia. Post-ERCP pancreatitis and bleeding correlated significantly with age, with post-ERCP pancreatitis occurring more frequently in patients aged < 60 years, and bleeding occurring more frequently in patients aged > 70 years. We observed a significant correlation between patient age and the diameter of the largest CBD stone, with stones > 12 mm occurring more frequently in patients > 60 years old.
CONCLUSION: Choosing a balloon size based on the largest stone diameter is safe and effective for removing CBD stones. Balloon size should not exceed 15 mm.

Abstract
OBJECTIVE To explore the expression and significance of Th17 and Treg cells in peripheral blood of patients with systemic lupus erythematosus (SLE). METHODS Thirty active SLE patients (including 17 SLE patients with lupus nephritis), 20 inactive SLE patients and 20 healthy controls were enrolled. The expressions of Th17 cells and CD4+CD25+Foxp3+Treg cells in peripheral blood mononuclear cells (PBMC) were evaluated by flow cytometry. The correlations between the expression of Th17 cells, CD4+CD25+Foxp3+Treg cells and disease activity (SLEDAI), as well as the ratios of Th17 cells and Treg cells (Th17/Treg) in SLE patients and healthy controls were analyzed respectively. RESULTS The expression of Th17 cells in PBMC of SLE patients was higher than that in healthy controls [(1.39 ± 0.60)% vs (0.80 ± 0.33)%, P < 0.01] while the expression of CD4+CD25+Foxp3+Treg cells decreased in SLE patients [(3.09 ± 1.54)% vs (6.04 ± 1.49)%, P < 0.01]. The increased expression of Th17 cells and reduced CD4+CD25+Foxp3+Treg cells in PBMC were positively correlated with SLEDAI and negatively correlated with complements C3 and C4. There were increased expression of Th17 cells and reduced CD4+CD25+Foxp3+Treg cells in PBMC of lupus nephritis versus SLE patients without nephritis. CONCLUSION There is an abnormal elevation of Th17 cells and decrease of CD4+CD25+Foxp3+Treg cells in PBMC of SLE patients. The imbalance between Th17 and Treg cells may play a critical role in the pathogenesis of SLE.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a typical malignancy in a background of chronic inflammation. Th17 cells (a major source of IL-17) constitute crucial components of infiltrating inflammatory/immune cells in HCC and can amplify inflammatory response via binding to interleukin-17 receptor (IL-17R). Thus, we investigated the expression and clinical significance of IL-17 and IL-17 receptor family cytokines in HCC. METHODS The expression and prognostic value of IL-17 and IL-17R (A-E) were examined in 300 HCC patients after resection. Six Th17 associated cytokines in serum (n = 111) were quantified using enzyme-linked immunosorbent assays. Phenotypic features of IL-17+ CD4+ T cells were determined by flow cytometry analysis. RESULTS High expression of intratumoral IL-17 and IL1-7RE were significantly associated with poorer survival (p = 0.016 and <0.001, respectively) and increased recurrence (both P < 0.001) of HCC patients. Moreover, intratumoral IL-17, individually or synergistically with IL-17RE, could predict HCC early recurrence and late recurrence. Also, peritumoral IL-17RE showed the prognostic ability in HCC (P < 0.001 for OS/TTR). Furthermore, expression levels of Th17 associated cytokines including IL-6, -22, -17R and TNF-α were increased in serum of HCC patients compared to haemangioma patients. Importantly, activated human hepatic stellate cells induced in vitro expansion of IL-17+ CD4+ T cells. CONCLUSIONS High expression of IL-17 and IL-17RE were promising predictors for poor outcome of HCC patients. The protumor power of IL-17 producing CD4+ T cells was probably involved in the crosstalk with different types of inflammatory/immune cells in HCC.

Abstract
BACKGROUND Interferon regulatory factor (IRF)-1 and IRF-2 are transcriptional factors that mediate interferons functions; the loss of IRF-1 expression and gain of IRF-2 expression were associated with malignant phenotype in multiple cancers. However, their roles in the progression of hepatocellular carcinoma (HCC) remain poorly described. METHODS Immunohistochemistry was used to analyze the nuclear expression of IRF-1/2 in a cohort of 332 HCC patients. The expression of IRF-1/2 in HCC cell lines with stepwise metastasis potential was determined by immunoblotting. Downregulation of IRF-1 or IRF-2 expression was mediated by shRNAs; a series of experiments were conducted to determine the changes of invasion ability and downstream molecular events. RESULTS High expression of IRF-1 was associated with good outcome (p<.001 for OS/TTR), while high expression of IRF-2 was relevant to increased recurrence probability (p=.049) in HCC patients. The combination of the 2 IRFs showed better predictive power than either factor alone. Immunoblotting analysis revealed that IRF-2/IRF-1 ratio was positively correlated with the metastatic potential in human HCC cell lines. Downregulation of IRF-2 led to sharply attenuated invasion ability, paralleled with a decreased expression of STAT3, p-STAT3(Ser727), and MMP9. While downregulation of IRF-1 caused a concurrent decrease in IRF-2, little or no change was displayed in IRF-2/IRF-1 ratio, invasion ability, and MMP9 expression. CONCLUSIONS IRF-1 and IRF-2 expression were associated with prognosis of HCC patients with opposite predictive power. IRF-2/IRF-1 ratio was associated with tumor invasion, probably through modulation of MMP9 expression mediated by STAT3.

Abstract
OBJECTIVE To investigate the frequency and clinical implication of JAK2 mutation in patients with myeloproliferative neoplasm(MPN)and the correlation between the mutation and thrombosis. METHODS The clinical and laboratory data of 107 MPN patients was retrospectively analyzed. JAK2 mutation were detected with allele-specific polymerase chain reaction (AS-PCR) and sequencing. The significance of the mutation in disease diagnosis and molecular pathogenesis and the correlation between the mutation and thrombosis was analysed. RESULTS JAK2 mutation was detected in 71 (66.4%) and thrombosis in 34 (31.8%) of the 107 MPN patients. Thrombosis occurred in 34.8% (16/46) of polycythemia vera (PV), 32.6% (14/43) of essential thrombocythemia (ET), and 22.2% (4/18) of primany myelofibrosis (PMF) patients. The difference among the 3 groups was not significant (χ(2) = 0.96, P > 0.05). The frequency of thrombosis in JAK2(+) MPN patients (82.4%, 28/34) was higher than that in JAK2(-) MPN patients (17.6%, 6/34) (χ(2) = 5.71, P < 0.05). The frequency of thrombosis in MPN patients > 60 years was higher (41.5%, 27/65) than that in patients < 60 years (16.7%, 7/42) (χ(2) = 7.28, P < 0.01). CONCLUSION JAK2 V617F mutation occurs in significant percentage of Chinese patients with MPN. Patients with JAK2 mutation and older age are more succeptible to thrombosis. JAK2 mutation screening in patients with unknown thrombosis is helpful to reveal the underlying latent-MPN.

Abstract
OBJECTIVES The aim of this study was to investigate the correlation between disc displacement types and locations of disc perforation in the temporomandibular joint (TMJ). METHODS 157 patients (162 joints) with disc perforation observed through arthroscopy were included in this study. The types of disc displacement were analysed by TMJ MRI before operation. The locations of disc perforation under arthroscopy were recorded. The correlation between types of disc displacement and locations of disc perforation was analysed by Fisher's exact test. RESULTS Medial disc perforation was observed in 55.6% of patients with anterolateral displacement without reduction, but was observed in only 3.7% of patients with pure anterior displacement, and was not observed in patients with anteromedial displacement without reduction. There was a statistically significant difference between these groups in the incidence of medial disc perforation. CONCLUSIONS There is a correlation between different disc displacements and locations of disc perforation. The incidence of medial disc perforation in patients with anterolateral displacement was significantly higher. The types of disc displacement may have direct influence over the locations of disc perforation.

Abstract
Essential thrombocythemia is frequently associated with abdominal thrombotic complications including portal cavernoma as a consequence of chronic portal vein thrombosis. Essential thrombocythemia in a latent form is difficult to identify at onset due to the absence of an overt disease phenotype. In the presented case report, the diagnosis of essential thrombocythemia was initially missed because the typical disease phenotype was masked by bleeding and hypersplenism. The correct diagnosis was only reached when the patient experienced persistent thrombocytosis and pseudohyperkalemia after a shunt operation.

Abstract
The genotype of Hepatitis C Virus (HCV) strains is an important determinant of the severity and aggressiveness of liver infection as well as patient response to antiviral therapy. Fast and accurate determination of viral genotype could provide direction in the clinical management of patients with chronic HCV infections. Using publicly available HCV nucleotide sequences, we built a global Position Weight Matrix (PWM) for the HCV genome. Based on the PWM, a set of genotype specific nucleotide sequence "signatures" were selected from the 5' NCR, CORE, E1, and NS5B regions of the HCV genome. We evaluated the predictive power of these signatures for predicting the most common HCV genotypes and subtypes. We observed that nucleotide sequence signatures selected from NS5B and E1 regions generally demonstrated stronger discriminant power in differentiating major HCV genotypes and subtypes than that from 5' NCR and CORE regions. Two discriminant methods were used to build predictive models. Through 10 fold cross validation, over 99% prediction accuracy was achieved using both support vector machine (SVM) and random forest based classification methods in a dataset of 1134 sequences for NS5B and 947 sequences for E1. Prediction accuracy for each genotype is also reported.

Abstract
OBJECTIVE To investigate the prevalence and the risk of natural anticoagulants such as plasma protein C (PC), protein S (PS) and antithrombin (AT) deficiency in thromboembolic patients with no evident acquired factors. METHODS Clotting assays on French STAGO autoanalyzer were used to detect the activity of plasma PC, PS and AT in 85 patients with thrombotic disease and 50 sex and age matched healthy controls. RESULTS Among the 85 enrolled patients (18 arterial and 67 venous thromboembolism), male to female ratio was 1.4 and the median age was 42 years (17-69). The activity of plasma PC, PS and AT in the pre-therapy thrombotic disease group, the thrombo-recurrence group, and the age < or = 45 years group were significantly lower than that is the healthy control group, the first thrombotic episodes group and the age > 45 years group respectively (P < 0.001, P < 0.01, P < 0.01). The overall deficiency rate of these three natural anticoagulants was 30.6%, PS deficiency was the commonest (10.6%), the second was PC deficiency (8.2%), AT deficiency and combined deficiency each accounted for 5.9%. CONCLUSION The PC, PS and AT protein deficiencies are frequent in Chinese thromboembolic patients, they are the independent risk factors for the thrombotic events and recurrence.

Abstract
Monkey studies were conducted for the preclinical safety assessment of SCH 412499, an adenovirus encoding p21, administered by subconjunctival injection prior to trabeculectomy for postoperative maintenance of the surgical opening. Biodistribution of SCH 412499 was minimal and there was no systemic toxicity. Findings included swollen, partially closed or shut eye(s) and transient congestion in the conjunctiva. A mononuclear cell infiltrate was present in the conjunctiva, choroid and other ocular tissues, but completely or partially resolved over time. Electroretinograms and visual evoked potentials revealed no adverse findings. Thus, the findings are not expected to preclude the clinical investigation of SCH 412499.
