Abstract
To explore the application value of serum Gal-13, GLP-1 and VEGF in the prevention and guidance of adverse pregnancy outcomes in gestational diabetes (GDM). A retrospective study with case-control method was used to select 1 012 GDM patients from Haikou Maternal and Child Health Hospital from January 2019 to December 2022 as the study objects, and they were divided into poor pregnancy outcome group (n=342) and good pregnancy outcome group (n=670) according to whether they had adverse pregnancy outcomes. The medical records of 521 healthy women with normal glucose metabolism were selected as the control group. Serum Gal-13 and GLP-1 were detected by enzyme-linked immunosorbent assay and VEGF was determined by IAMMGE specific protein analyzer. After comparing the differences of the above factors among the three groups, multivariate logistic regression model was used to analyze the influencing factors of adverse pregnancy outcomes in GDM patients, and ROC curve was drawn to analyze the predictive value of serum Gal-13, GLP-1 and VEGF levels on adverse pregnancy outcomes in GDM patients. The results showed that Fasting blood glucose (FPG), glycosylated hemoglobin (HbA1c) and fasting insulin (FINS) in the adverse pregnancy outcome group were 5.92(4.98, 6.41) mmol/L, 5.32(4.96, 5.47)%, 62.56(49.21,99.50) pmol/L, VEGF was 495.47(389.14, 567.13) ng/L, TSH was 1.48(1.34, 1.58) mIU/L, right ventricular myocardial work index (Tei index) was 0.59(0.45, 0.67), 89 cases of elderly parturients; FPG was 4.45(4.16, 5.03) mmol/L, HbA1c was 5.04(4.86, 5.29)%, FINS was 57.41(46.90, 74.08) pmol/L, VEGF was 405.84(348.02, 462.68) ng/L, TSH was 1.42(1.25, 1.50) mIU/L, Tei index was 0.50(0.47, 0.64), there were 142 cases of old women. In the control group, FPG was 4.33(4.05, 4.75) mmol/L, HbA1c was 5.01(4.13, 5.18)%, FINS was 38.48(36.76, 41.72) pmol/L and VEGF was 302.45(283.14, 336.56) ng/L, TSH was 1.32(1.24, 1.47)mIU/L, Tei index was 0.48(0.39, 0.59), and there were 106 elderly parturiencies. The levels of FPG, HbA1c, FINS, VEGF, TSH and Tei index in the adverse pregnancy outcome group and the good pregnancy outcome group were higher than those in the control group, and the proportion of elderly parturients was higher than that in the control group, and the adverse pregnancy outcome group was higher than that in the good pregnancy outcome group. The differences were statistically significant (H=8.620, P<0.001, H=2.616, P=0.014, H=6.156, P<0.001, H=3.051, P<0.001, H=4.892, P=0.044, χ2=2.548, P=0.045). In the adverse pregnancy outcome group, Gal-13 was 15.27(8.35, 24.45)pg/ml, GLP-1 was 9.27(8.26, 12.35) pmol/L and FT4 was 11.59(9.67, 13.48) pmol/L. In the group with good pregnancy outcome, Gal-13 was 25.34(20.14, 29.73) pg/ml, GLP-1 was 12.38(10.25, 15.63) pmol/L and FT4 was 13.86(10.67, 15.10) pmol/L. In the control group, Gal-13 was 31.21(27.48, 34.45) pg/ml, GLP-1 was 11.34(10.40, 14.37) pmol/L and FT4 was 14.15(10.75, 15.43)pmol/L. The levels of Gal-13, GLP-1 and FT4 in the adverse pregnancy outcome group and the good pregnancy outcome group were significantly lower than those in the control group, and the adverse pregnancy outcome group was lower than that in the good pregnancy outcome group. The differences were statistically significant (H=6.458, P=0.011, H=8.445, P<0.001, H=5.694, P<0.001). The levels of Gal-13 and GLP-1 in normal blood glucose recovery group were higher than those in non-normal blood glucose recovery group, and the levels of VEGF were lower than those in non-normal blood glucose recovery group (P<0.05).In multivariate logistic regression analysis, Gal-13, GLP-1, VEGF, TSH, FT4 and Tei indexes were independent influencing factors for adverse pregnancy outcomes with GDM (P<0.05). ROC curve analysis showed that the AUC of Gal-13, GLP-1 and VEGF alone in predicting adverse pregnancy were 0.779, 0.761 and 0.615, respectively. The value of the combined diagnosis was the highest (AUC=0.912), the sensitivity was 90.1%, and the specificity was 80.0%. In conclusion, Gal-13, GLP-1 and VEGF may be independent influencing factors for adverse pregnancy outcomes in GDM patients, and the combined detection of the three may help to improve the auxiliary diagnostic efficacy for predicting adverse pregnancy outcomes.

Abstract
Objective: To compare the efficacy and safety of short-course radiotherapy with total neoadjuvant therapy (SCRT-TNT) and neoadjuvant chemoradiotherapy (nCRT) in patients with locally advanced middle and low rectal cancer. Methods: A retrospective cohort study was carried out. A of 126 patients with locally advanced middle and low rectal cancer who were treated in the Department of Gastrointestinal Cancer Surgery of Fujian Cancer Hospital from September 2016 to March 2020 were enrolled, including 73 males and 53 females, with a mean age of (56.5±9.8) (23-77) years. Based on neoadjuvant regimen (nCRT treatment was performed before December 2018 and SCRT-TNT treatment was carried out after January 2019), patients were divided into nCRT group (n=68) and SCRT-TNT group (n=58). There were no statistically significant differences in age, sex, distance from tumor to anal verge, Eastern Cooperative Oncology Group (ECOG) performance status and clinical TNM stage between the two groups (all P>0.05). Patients in both groups received pelvic intensity-modulated radiotherapy (IMRT). The radiotherapy dose of nCRT group was 50Gy/25 times/5 weeks. Patients in nCRT group received oral capecitabine chemotherapy during radiotherapy and underwent surgery 6-8 weeks after chemoradiation. However, patients in SCRT-TNT group received CapeOX regimen (oxaliplatin+capecitabine) for 2 cycles of induction chemotherapy, followed by short-course radiotherapy (25Gy/5 times/5 days), then underwent a radical surgery two weeks after completion of consolidation chemotherapy (4 cycles). The adverse reactions, perioperative safety and efficacy of neoadjuvant therapy were compared and analyzed between the two groups. Results: Both groups completed neoadjuvant therapy as planned. Patients in nCRT group and SCRT-TNT group had similar incidence of adverse reactions to radiotherapy and chemotherapy, however, there were no statistically significant differences in the incidence of surgical complications, operation time, intraoperative blood loss and postoperative length of hospital stay (all P>0.05). A total of 119 patients underwent total mesenterectomy (TME), including 64 patients in the nCRT group and 55 patients in the SCRT-TNT group, all with R0 resection. The pathological complete response (pCR) rate was 10.9% (7/64) in the nCRT group and 25.5% (14/55) in the SCRT-TNT group, respectively, with a statistically significant difference (P=0.038). Two years after surgery, there was no statistically significant difference in local recurrence rate and overall survival rate between the two groups (both P>0.05). However, the clinical metastasis rate of SCRT-TNT group was significantly lower than that of nCRT group (20.3% vs 9.1%), with a statistically significant difference (P<0. 05). Conclusion: SCRT-TNT do not increase the adverse reactions of radio chemotherapy and perioperative risks in the treatment of locally advanced middle and low rectal cancer, and the tumor regression effect is good, which is worthy of clinical promotion.

Abstract
Background Previous studies have demonstrated that solid organ transplant (SOT) patients undergoing primary total hip arthroplasty (THA) are at an increased risk of postoperative complications. The purpose of this study is to use a large, national database to investigate revision THA (rTHA) outcomes in SOT patients. Methods Nationwide Readmissions Database (NRD) from 2010-2018 was used, and ICD-9 and ICD-10 codes were used to identify all patients who underwent rTHA, including those with history of SOT. Propensity score matching (PSM) was used to analyze rTHA outcomes in SOT patients comparted to matched controls. Separate analysis performed for patients undergoing rTHA for prosthetic joint infection (PJI) vs other causes. Results A total of 414,756 rTHA, with 1837 of those being performed in SOT patients, were identified. Of these, 65,961 and 276 were performed for PJI in non-SOT and SOT patients, respectively. For non-PJI patients, SOT patients had higher 90-day all-cause readmission rates (24.0% vs 19.4%, P = .03) but lower rate for readmission related to rTHA (6.0% vs 9.2%, P = .03), but no difference readmission for specific rTHA complications, mortality (0.6% vs 1.3%, P = .20), or revision rTHA. Of PJI patients, SOT patients had no difference in overall 90-day readmission (38.6 vs 31.3%, P = .280), readmission for specific rTHA complications, re-revision, or mortality (4.7% vs 6.0%, P = .63). Conclusions SOT patients undergoing rTHA for aseptic reasons are higher risk of overall readmission but lower risk of readmission related to rTHA than appropriately matched controls. SOT PJI patients undergoing had similar rates of readmission, mortality, and revision surgery compared to matched non-SOT PJI patients.

Abstract
BACKGROUND The purpose of this study was to compare the short-term complications between transplant and nontransplant patients who undergo hip arthroplasty for femoral neck fractures (FNFs). Additionally, we sought to further compare the outcomes of total hip arthroplasty (THA) versus hemiarthroplasty (HA) within the transplant group. METHODS This was a retrospective review utilizing the Nationwide Readmissions Database. Transplant patients were identified and stratified based on transplant type: kidney, liver, or other (heart, lung, bone marrow, and pancreas). Outcomes of interest included index hospitalization mortality, perioperative complications, length of stay, costs, hospital readmission, and surgical complications within 90 days of discharge. RESULTS From 2010 to 2018, a total of 881,061 patients underwent THA or HA for FNFs, of which 2163 (0.2%) were transplant patients. When compared with nontransplant patients, all transplant patients had an increased risk of requiring blood transfusion (odds ratio [OR] = 1.51, P = .001), acute kidney injury (OR = 2.02, P < .001), and discharge to facility (OR = 1.67, P = .001) while having increased index hospitalization length of stay and costs. Liver and other transplant patients had an increased risk of readmission within 90 days (OR = 1.82, P < .001 and OR = 1.60, P = .014 respectively). Subgroup analysis for transplant patients comparing HA with THA demonstrated no differences in perioperative complication rates and decreased hospitalization length of stay and cost associated with THA. CONCLUSION In this retrospective cohort study, transplant patients had an increased risk of requiring blood transfusions and acute kidney injury after hip arthroplasty for FNFs. There were no differences in short-term complications between transplant patients treated with HA versus THA. LEVEL OF EVIDENCE 3 (Retrospective cohort study).

Abstract
BACKGROUND Assessing academic productivity allows academic departments to identify the strengths of their scholarly contribution and provides an opportunity to evaluate areas for improvement.
AIM To provide objective benchmarks for departments seeking to enhance academic productivity and identify those with significant improvement in recent past.
METHODS Our study retrospectively analyzed a cohort of orthopaedic faculty at United States-based academic orthopaedic programs. 5502 full-time orthopaedic faculty representing 178 programs were included in analysis. Variables included for analysis were National Institutes of Health funding (2014-2018), leadership positions in orthopaedic societies (2018), editorial board positions of top orthopaedic journals (2018), total number of publications and Hirsch-index. A weighted algorithm was used to calculate a cumulative score for each academic program. This study was performed at a large, United States medical school.
RESULTS All 178 programs included in analysis were evaluated using the comprehensive weighted algorithm. The five institutions with the highest cumulative score, in decreasing order, were: Washington University in St. Louis, the Hospital for Special Surgery, Sidney Kimmel Medical College (SKMC) at Thomas Jefferson University, the University of California, San Francisco (UCSF) and Massachusetts General Hospital (MGH)/Brigham and Women’s/Harvard. The five institutions with the highest score per capita, in decreasing order, were: Mayo Clinic (Rochester), Washington University in St. Louis, Rush University, Virginia Commonwealth University (VCU) and MGH/Brigham and Women’s/Harvard. The five academic programs that had the largest improvement in cumulative score from 2013 to 2018, in decreasing order, were: VCU, SKMC at Thomas Jefferson University, UCSF, MGH/Brigham and Women’s/Harvard, and Brown University.
CONCLUSION This algorithm can provide orthopaedic departments a means to assess academic productivity, monitor progress, and identify areas for improvement as they seek to expand their academic contributions to the orthopaedic community.

Abstract
BACKGROUND Previous studies have demonstrated that solid organ transplant (SOT) patients undergoing primary total knee arthroplasty (TKA) are at an increased risk of postoperative complications. The purpose of this study is to utilize a large, national database to investigate revision TKA (rTKA) outcomes in SOT patients. METHODS This was a retrospective review utilizing the Nationwide Readmissions Database (NRD) and ICD-9 codes to identify patients who underwent rTKA from 2010-2014 with a history of at least one SOT. Propensity-score-matching (PSM) was used to compare rTKA outcomes in SOT patients compared to matched patients without SOT. RESULTS A total of 303,867 rTKAs, with 464 of those being performed in SOT patients, were included in the study. Of these, 71,903 and 182 were performed for PJI in non-SOT and SOT patients, respectively. rTKA was performed most frequently in kidney transplant patients (53.0%) followed by liver transplant patients (34.3%). For non-PJI patients, SOT patients had a higher 90-day readmission rate than matched non-SOT rTKA patients (23.2% vs 12.6%, p = 0.006). However, there were no differences in 90-day readmission rates for specific rTKA complications, subsequent revision rTKA, or mortality. Among patients undergoing rTKA for PJI, there was no difference in overall 90-day readmission rate, readmission for specific rTKA complications, subsequent revision rTKA, or mortality. CONCLUSIONS While the increased medical comorbidities associated with SOT place patients at increased risk for complications following rTKA, it appears that SOT alone does not do so when patients are matched based on overall medical comorbidity.

Abstract
BACKGROUND Ogilvie syndrome (OS) is a rare but serious condition seen in the postoperative period. This was an epidemiologic study using data from the National Inpatient Sample from 2005 to 2014 to look at incidence, risk factors, and outcomes associated with OS after primary spine fusion. METHODS International Classification of Diseases, Ninth Revision codes were used to identify patients who underwent spine fusion surgery. Patients were separated into 2 cohorts based on the diagnosis of OS. Outcome measures and risk factors for cohorts were analyzed using multivariate logistic regression and compared. RESULTS Over the 10-year study period, 3,884,395 patients underwent primary spine fusion surgery. Among these, 0.04% developed OS during the index hospitalization. The greatest incidence seen in primary fusion involved the thoracic spine (0.15%). OS was more common after spine fusion for spine deformity (P < 0.001). Patients with OS were more likely to be men (P < 0.001), older (P < 0.0001), and have more comorbidities (P < 0.0001). Patients with OS were more likely to require postoperative blood transfusions (odds ratio [OR], 3.39; 95% confidence interval [CI], 2.51-4.59; P < 0.001) and sustain any complication (OR, 4.20; 95% CI, 3.17-5.57; P < 0.001). Patients with OS had a longer length of stay (15.7 vs. 3.9 days; P < 0.001) and increased average hospitalization cost ($63,037.03 vs. $26,792.19; P < 0.001). The development of OS was associated with fluid electrolyte disorder (OR, 4.06; 95% CI, 2.99-5.51; P < 0.001). CONCLUSIONS OS is a rare but serious complication of primary spine fusion surgery. Identifying the specific risk factors, symptoms, and potential complications related to OS is critical to aid in decreasing the significant morbidity associated with its development.

Abstract
BACKGROUND CONTEXT Computer-assisted navigation (CAN) has emerged in spine surgery as an approach to improve patient outcomes. While there is substantial evidence demonstrating improved pedicle screw accuracy in CAN as compared to conventional spinal fusion (CONV), there is limited data regarding clinical outcomes and utilization trends in the United States. PURPOSE The purpose of this study was to determine the utilization rates of CAN in the United States, identify patient and hospital trends associated with both techniques, and to compare their results. STUDY DESIGN Retrospective review of national database. PATIENT SAMPLE Nationwide Inpatient Sample (NIS), United States national database. OUTCOME MEASURES CAN utilization, mortality, medical complications, neurologic complications, discharge destination, length of hospital stay, cost of hospital stay. METHODS The NIS database was queried to identify patients undergoing spinal fusion with CAN or CONV. CAN and CONV utilization were tracked by year and anatomic location (cervical, thoracic, lumbar/lumbosacral). Patient demographics, hospital characteristics, index length of stay (LOS), and cost of stay (COS) were compared between the cohorts. After multivariate adjustment, index hospitalization clinical outcomes were compared. RESULTS A total of 4,275,413 patients underwent spinal fusion surgery during the study period (2004 to 2014). CONV was performed in 98.4% (4,208,068) of cases and CAN was performed in 1.6% (67,345) of cases. The utilization rate of CAN increased from 0.04% in 2004 to 3.3% in 2014. Overall, CAN was performed most commonly in the lumbar/lumbosacral region (70.4%) compared to the cervical (20.4%) or thoracic (9.2%) regions. When normalized to region-specific rates of fusion with any technique, the proportional utilization of CAN was highest in the thoracic spine (2.7%), followed by the lumbar/lumbosacral (2.2%) and cervical (0.9%) regions. CAN utilization was positively correlated with patient factors including increasing age and number of medical comorbidities. Multivariate adjusted clinical outcomes demonstrated that compared to CONV, CAN was associated with a statistically significant decreased risk of mortality (0.28% vs 0.31%, OR=0.67, 95% CI: 0.46-0.97, p=.035) and increased risk of blood transfusions (9.1% vs 6.7%, OR=1.19, 95% CI: 1.02-1.39, p=.032). However, there was no difference in risk of neurologic complications. CAN patients had an increased average LOS (4.44 days vs. 3.97 days, p<.0001) and average COS ($34,669.49 vs $26,784.62, p<.0001) compared to CONV patients. CONCLUSIONS CAN utilization increased in the United States from 2004-2014. Use of CAN was proportionately higher in the thoracic and lumbar/lumbosacral regions and in older patients with more comorbidities. Given the continued trend towards increased CAN utilization, large-scale studies are needed to determine the impact of this technology on long-term clinical outcomes.

Abstract
STUDY DESIGN Bibliometric literature review. OBJECTIVE The aim of this study was to recognize and analyze the most frequently cited manuscripts published in the journal Spine. SUMMARY OF BACKGROUND DATA Although the journal Spine is considered a premiere location for distributing influential spine research, no previous study has evaluated which of their publications have had the most impact. Knowledge and appreciation of the most influential Spine publications can guide and inspire future research endeavors. METHODS Using the Scopus database, the 100 most cited articles published in Spine were accessed. The frequency of citations, year of publication, country of origin, level-of-evidence (LOE), article type, and contributing authors/institutions were recorded. The 10 most cited articles (per year) from the past decade were also determined. RESULTS "Guidelines For The Process Of Cross-Cultural Adaptation Of Self-Report Measures" by Beaton DE was the most cited article with 2960 citations. 2000 to 2009 (n = 46) was the most productive period. A LOE of III (n = 35) followed by II (n = 34) were the most common. Deyo RA (n = 8), Bombardier C (n = 6), and Waddell G (n = 6) produced the most articles. University of Washington (n = 8) and University of Toronto (n = 8) ranked first for institutional output. Clinical Outcome (n = 28) was the most recurring article topic. The United States (n = 51) ranked first for country of origin. CONCLUSION Using citation analysis as an objective proxy for influence, certain publications can be distinguished from others due to their lasting impact and recognition from peers. Of the top cited Spine publications, many pertained to clinical outcomes (28%) and had a LOE of I, II, or III (60%). Although older publications have had longer time to accrue citations, those in the most recent decade comprise this list almost 2:1. Knowledge of these "classic" publications allows for a better overall understanding of the diagnosis, management, and future direction of spine health care.Level of Evidence: 3.

Abstract
BACKGROUND CONTEXT Metastatic spine disease (MSD) is becoming more prevalent as medical treatment for cancers advance and extend survival. More MSD patients are treated surgically to maintain neurological function, ambulation, and quality of life. PURPOSE The purpose of this study was to use a large, nationally representative database to examine the trends, patient outcomes, and health-care resource utilization associated with surgical treatment of MSD. DESIGN This was an epidemiologic study using national administrative data from the Nationwide Readmissions Database (NRD). PATIENT SAMPLE All patients in the NRD from 2010 to 2014 who underwent spinal surgery were included in the study. OUTCOME MEASURES Mortality, blood transfusion, complications, length of stay, cost, and discharge location during index hospitalization as well as hospital readmission and revision surgery within 90-days of surgery were analyzed. METHODS International Classification of Diseases, Ninth Revision, (ICD-9) codes was used to identify patients of interest within the NRD from 2010 to 2014. Patients were separated into two cohorts - those with MSD and those without. Trends for surgical treatment of MSD were assessed and outcomes measures for both cohorts were analyzed and compared. RESULTS The number of surgical treatments for MSD increased from 6,007 in 2010 to 7,032 in 2014 (p-trend<.0001) which represented a 17.1% increase. During index hospitalization, MSD patients had an increased risk of mortality (odds ratio [OR]=3.22, 95% confidence interval [CI]: 2.85-3.63, p<.0001), blood transfusion (OR=2.93, 95% CI: 2.66-3.23, p<.0001), any complication (OR=1.24, 95% CI: 1.18-1.31, p<.0001), and discharge to skilled nursing facility (OR=1.51, 95% CI:1.41-1.61, p<.0001). MSD patients had longer average length of stay (13.05 vs. 4.56 days, p<.0001) and cost ($49,421.75 vs. $26,190.37, p<.0001) during index hospitalization. Furthermore, MSD patients had an increased risk of hospital readmission (OR=2.82, 95% CI: 2.68-2.96, p<.0001), readmission for surgical site infection (OR=2.38, 95% CI: 2.20-2.58, p<.0001), and readmission with neurologic deficits (OR=1.62, 95% CI: 1.27-2.06, p<.0001) despite a decreased risk of revision fusion (OR=0.71, 95% CI: 0.53-0.96, p=.026). CONCLUSIONS The number of MSD patients who undergo surgical treatments is increasing. Not only do these patients have worse outcomes during index hospitalization, but they are also at an increased risk of hospital readmission for surgical site infection and neurologic complications. These findings stress the need for multidisciplinary perioperative treatment plans that mitigate risks and facilitate quick, effective recovery in these unique, at-risk patients.

Abstract
Background Technology-assisted total hip arthroplasty (TA-THA) using either computer-assisted navigation or robotic assistance has become increasingly more popular. The purpose of this study was to examine the trends and patient factors associated with TA-THA. Methods This is a retrospective review utilizing the National Inpatient Sample, a large national database incorporating inpatient hospitalization information. International Classification of Diseases, 9th Revision codes were used to identify patients with hip osteoarthritis who underwent primary total hip arthroplasty (THA). Patients were then separated into those who underwent TA-THA or conventional THA. Outcomes of interest included annual TA-THA utilization; patient and hospital characteristics associated with TA-THA; and trends for length of stay (LOS), cost, and discharge to home. Results From 2005 to 2014, a total of 2,588,304 patients with hip osteoarthritis who underwent THA were identified in the National Inpatient Sample database. Of those, 39,700 (1.5%) underwent TA-THA. The number of TA-THA procedures increased from 178 (0.1% of all THA) in 2005 to 10,045 (3.0% of all THA) in 2014, which represented a 30-fold increase in incidence (P-trend <.0001). TA-THA was associated with Hispanic race, higher patient income, and the Western region of the United States. During the study period, there was a trend toward decreased LOS and increased discharge to home for both TA-THA and conventional THA. TA-THA was associated with higher inpatient cost. Conclusion TA-THA is being increasingly used in the United States and is associated with specific patient factors. However, the value of TA-THA compared to conventional THA remains unclear and should be assessed with future research. Level of Evidence III (retrospective cohort study).

Abstract
AIMS We aimed to examine the long-term mechanical survivorship, describe the modes of all-cause failure, and identify risk factors for mechanical failure of all-polyethylene tibial components in endoprosthetic reconstruction. METHODS This is a retrospective database review of consecutive endoprosthetic reconstructions performed for oncological indications between 1980 and 2019. Patients with all-polyethylene tibial components were isolated and analyzed for revision for mechanical failure. Outcomes included survival of the all-polyethylene tibial component, revision surgery categorized according to the Henderson Failure Mode Classification, and complications and functional outcome, as assessed by the Musculoskeletal Tumor Society (MSTS) score at the final follow-up. RESULTS A total of 278 patients were identified with 289 all-polyethylene tibial components. Mechanical survival was 98.4%, 91.1%, and 85.2% at five, ten and 15 years, respectively. A total of 15 mechanical failures were identified at the final follow-up. Of the 13 all-polyethylene tibial components used for revision of a previous tibial component, five (38.5%) failed mechanically. Younger patients (< 18 years vs > 18 years; p = 0.005) and those used as revision components (p < 0.001) had significantly increased rates of failure. Multivariate logistic regression modelling showed revision status to be a positive risk factor for failure (odds ratio (OR) 19.498, 95% confidence interval (CI) 4.598 to 82.676) and increasing age was a negative risk factor for failure (OR 0.927, 95% CI 0.872 to 0.987). Age-stratified risk analysis showed that age > 24 years was no longer a statistically significant risk factor for failure. The final mean MSTS score for all patients was 89% (8.5% to 100.0%). CONCLUSION The long-term mechanical survivorship of all-polyethylene tibial components when used for tumour endoprostheses was excellent. Tumour surgeons should consider using these components for their durability and the secondary benefits of reduced cost and ease of removal and revision. However, caution should be taken when using all-polyethylene tibial components in the revision setting as a significantly higher rate of mechanical failure was seen in this group of patients.

Abstract
A route for synthesizing monodisperse magnetic nanocrystallites of maghemite, [Formula: see text]-Fe2O3, with various sizes has been revisited. A systematic investigation of three [Formula: see text]-Fe2O3 nanocrystalline samples by different techniques has been performed to characterize their size-dependent magnetic properties. Zero-field-cooled and field-cooled magnetization measurements reveal that the superparamagnetic blocking temperatures are around 230 K, 170 K, and 50 K for the 15.0 nm, 11.8 nm, and 6.1 nm nanocrystallites, respectively. Low-temperature Mössbauer spectra show that all three nanocrystallites have the maghemite structure with all the vacancies in the B-sites. Furthermore, detailed analysis shows that there are more vacancies on the B-sites for the 6.1 nm nanocrystallites compared to 0.33 for the bulk maghemite.

Abstract
BACKGROUND An uncircumcised male infant with a history of urinary tract infection (UTI), physiologic phimosis, and a normal renal ultrasound is a common patient referred to pediatric urology clinics. Topical steroid creams have been shown to effectively release physiologic phimosis. OBJECTIVE The objective of this study was to test the hypothesis that use of steroid cream for physiologic phimosis is associated with a lower UTI recurrence in uncircumcised male infants with normal renal ultrasounds. STUDY DESIGN Uncircumcised males younger than 12 months referred for a UTI with a normal renal ultrasound were included. A longitudinal data set was created, and recurrent UTIs were identified. The proportion with a recurrent UTI was compared between those who received a prescription for a steroid cream for phimosis and those who did not. The morbidity of the initial and recurrent UTIs was also described. The association of recurrent UTI with vesicoureteral reflux (VUR) was also evaluated. RESULTS A total of 192 uncircumcised males with a median age of 5.8 months (interquartile range [IQR]: 3.5-7.9 months) were included. Twenty-seven patients were treated with a course of betamethasone valerate 0.1% cream, and 165 were not (Summary Table). There were no significant differences between groups in the frequency of voiding cystourethrogram (VCUG), diagnosis of VUR, or use of continuous prophylactic antibiotics (CAP). During a median follow-up of 8.7 months (IQR: 3.1-17.5 months), none of the patients treated with steroid cream had a recurrent UTI compared with 27 of 165 (16%) patients not treated (P = 0.02). Among the 173 patients whose initial UTI was febrile, recurrent febrile UTIs occurred in no treated patients and 23 of 150 (15%) untreated patients (P = 0.047). DISCUSSION The results of this study are consistent with those of a previous randomized trial of steroid cream for physiologic phimosis which found lower recurrent UTI in those whose foreskins became retractable. In addition, the results are consistent with the declining incidence of UTIs in uncircumcised males mirroring the natural history of physiologic phimosis resolving. This study is limited by its retrospective nature and non-standardized follow-up. CONCLUSION The use of steroid cream for physiologic phimosis is associated with a decreased risk of recurrent UTIs in uncircumcised male infants with a normal renal ultrasound. In this group, steroid cream for physiologic phimosis is a well-tolerated and simple alternative to circumcision to potentially decrease risk of recurrent UTI.

Abstract
Background Curettage is widely used in orthopedic oncology; the defect created frequently requires filling for mechanical and functional stability for the bones and adjacent joint. Allograft, bone graft substitute, and polymethyl methacrylate (PMMA) are the most common substances used each with their benefits and drawbacks. The aim of the study is to show that good functional result can be achieved with curettage and bone filler, regardless of type. Methods A series of 267 cases were reviewed between 1994 and 2015 who received curettage treatment and placement of a bone filler. Endpoints included fracture, infection, cellulitis, pulmonary embolism, and paresthesia. Complication rates at our single institution were compared against literature values for three study cohorts: allograft, bone graft substitute, and PMMA bone fillers. Friedman test, Wilcoxon test, and Z-score for two populations were used to compare our subset against literature values and between different bone filling types. Results Our cases included 18 autografts, 74 allografts, 121 bone graft substitute, and 54 PMMA of which the bulk of complications occurred. Our overall complication rate was 3.37%. Allograft has a complication rate of 1.35%, bone graft substitute of 4.13%, and PMMA of 5.56%. Other techniques did not yield any complications. Combination filling techniques PMMA + allograft and PMMA + bone graft substitute had sample sizes too small for statistical comparison. Statistical comparison yielded no significant difference between complications in any of the filling groups (P = 0.411). Conclusions Some has even argued that bone defects following curettage do not require bone filling for good outcome. However, many structural or biologic benefits that aid in earlier return to functionality can be conferred by filling large bone defects. There was no significant difference in postoperative complication rates between allograft, bone graft substitute, and PMMA when compared at our institution and with literature values. Nevertheless, one complication with a large defect filled with allograft, requiring a subsequent reconstruction using vascularized fibular graft. Taking everything into account, we see bone graft substitute as a suitable alternative to other bone filling modalities.

Abstract
BACKGROUND The purpose of this study was to evaluate the outcomes following hemiarthroplasty (HA) for femoral neck fractures (FNFs) in patients with Parkinson's disease (PD) compared with patients without PD. METHODS This was a retrospective review utilizing the Nationwide Readmissions Database, a national database incorporating inpatient hospitalization information. Using the Nationwide Readmissions Database, patients who underwent HA for FNF between 2010-2014 were identified. International Classification of Diseases, 9th Revision, codes were used to find a subset of patients with PD. Primary outcomes of interest included death, hospital readmission, periprosthetic fracture, postoperative dislocation, any revision surgery, and revision surgery for instability, fracture, or infection. RESULTS There were a total of 7721 (4%) patients with PD. There was no difference in the risk of death or any postoperative complications during index hospitalization for these patients. However, PD patients had an increased risk of hospital readmission (odds ratio [OR] = 1.13, 95% confidence interval [CI]: 1.02-1.26) and postoperative dislocation (OR = 2.10, 95% CI: 1.58-2.80) within 90 days of surgery. PD patients also had an increased risk of revision surgery for instability (OR = 2.20, 95% CI: 1.48-3.28), despite no difference in the risk of any revision surgery, revision surgery for fracture, or revision surgery for infection. CONCLUSION In this retrospective cohort study, PD patients who underwent a HA for FNF had a greater risk of postoperative dislocation and revision surgery for instability within 90 days. These findings are not only important to consider when managing these at-risk patients but also stress the need to allocate operative and postoperative resources to prevent and treat instability.

Abstract
From April 2017 to April 2018, three male patients aged 46-71 years with large area burns were treated in our hospital. Acute acalculous cholecystitis (AAC) symptoms of the patients began to appear 15-81 days after injury. AAC was diagnosed 24-81 days after injury. Ultrasound-guided percutaneous transhepatic cholecystostomy was performed 26-82 days after injury. The symptoms subsided in 2 patients, and cholecystectomy was performed in 1 patient with gallbladder perforation 94 days after injury. The patients were cured and discharged 41-118 days after injury. No recurrence of cholecystitis occurred during 8-9 months of follow-up after discharge.

Abstract
Objective: To investigate the relationship between serum 25-hydroxyvitamin D[25(OH) D] levels and idiopathic benign paroxysmal positional vertigo (BPPV) in female patients. Methods: A total of 67 women diagnosed with idiopathic BPPV were selected as the study group between January and December 2016 in Ningbo No.2 Hospital, and 95 healthy women without a history of vertigo or dizziness were selected as the control group. The data of height, weight, histories of hypertension and diabetes mellitus were collected, and serum 25(OH) D levels were measured. The number of the recurrence and canalith repositioning maneuvers were recorded during the one-year follow-up. Results: No significant differences of age, body mass index, histories of hypertension and diabetes mellitus between patients with BPPV and healthy controls (all P>0.05) .The serum 25 (OH) D levels were significantly lower in patients with idiopathic BPPV than in healthy controls [(50.56±13.36) nmol/L vs (56.55±16.21) nmol/L, t=-2.485, P=0.014]. BPPV patients with low level of 25(OH) D showed a significant increase in the number of canalith repositioning maneuvers required and the recurrence rate. The regression analyses demonstrated that 25(OH)D deficiency was associated with BPPV with an odds ratio of 2.054 (95% CI: 1.088-3.877, P=0.026). Conclusion: 25(OH) D deficiency may be a risk factor of BPPV.

Abstract
Studies have shown that 48.59% of benign prostate hyperplasia (BPH) is combined with metabolic syndrome (MetS). The mainstream view supports the correlation between MetS and BPH, but the pathogenesis of MetS‐BPH is not fully understood. Four hundred and seventy‐four men, aged 47 years or older, were recruited into this study by consecutive routine physical examination programs, and several parameters were obtained from each participant. Based on the diagnosis of BPH, MetS, and MetS‐BPH, the participants were divided into BPH and Non‐BPH groups, MetS and Non‐MetS groups, as well as MetS‐BPH and Non‐MetS‐BPH groups. The values of the obtained parameters were evaluated using Student's t‐test, chi‐square test, and logistic regression analysis. The value of estradiol (E2) was higher in the diseased groups (BPH, MetS, and MetS‐BPH groups) compared with the corresponding control groups (Non‐BPH, Non‐MetS, and Non‐MetS‐BPH groups), and the differences were statistically significant. Also, E2 had an independent association with BPH (OR = 2.286, 95% CI: 1.723–3.593, p < 0.001), MetS (OR = 1.406, 95% CI: 0.585–2.315, p < 0.001), and MetS‐BPH (OR = 1.249, 95% CI: 0.795–1.962, p < 0.001). Regarding SNPs of CYP19A1 gene, both the rs4646 genotypes (CC, CA, and AA) and the rs700518 genotypes (CC, CT, and TT) were present in every group, and all genotypes had statistically significant differences between the diseased and corresponding control groups. However, only the TT genotype of rs700518 was independently associated with BPH, MetS, and MetS‐BPH after adjusting for age. The TT genotype of rs700518 is an independent risk factor for the MetS‐BPH populations, and the CYP19A1 gene regulation of estrogen leads to MetS‐BPH.

Abstract
Objective: To detect the methylation status of DLC-1 gene in the patients with myelodysplastic syndrome(MDS), the effect of abnormal methylation of DLC-1 gene on the expression of DLC-1 gene, the clinical significance of methylation of DLC-1 gene in MDS patients, and the effect of decitabine on DLC-1 gene expression. Methods: A total of 43 MDS patients were treated in Fujian Medical University Union Hospital from 2013 to 2015. Methylation status of DLC-1 gene in MDS patients were detected by the methylation specific PCR(MSP). The expression of DLC-1 gene mRNA was determined with real-time fluorescence quantitative PCR(RTFQ-PCR). MDS patients were divided into 5 groups (very low-risk, low-risk, intermediate-risk, high-risk and very high-risk, n=0, 8, 7, 18, 10) according to WPSS classification. And the clinical significance of methylation of DLC-1 gene in patients with MDS were investigated. In order to investigate the change in gene methylation and expression of DLC-1 gene after treatment with decitabine, methylation statuses of DLC-1 gene in MDS patients before and after be treated with decitabine were detected by the bisulfite sequencing PCR(BSP). The expressions of DLC-1 gene mRNA of these patients were determined with RTFQ-PCR. Results: Hypermethylation of CpG island of DLC-1 gene was observed in 55.16%(22/43)MDS patients. The expressions of DLC-1 gene mRNA in methylation positive patients were significantly lower than that in methylation negative patients (0.32±0.06 vs 0.91±0.11)(P=0.008). For MDS patients, the DLC-1 methylation rate of intermediate-and high-risk patient was 21/35, which was significantly higher than that of low-risk patient(1/8, P=0.006). The methylation status of DLC-1 gene were monitored in 8 patients before and after treatment with the decitabine (decitabine 20 mg/m(2,) d1-d5/d28, more than 4 courses) , the methylation rate of DLC-1 gene dropped from 57.50%±5.11% to 14.13%±2.07% after treatment(P=0.010). The expression of DLC-1 gene increased after treatment with decitabine(0.67±0.08 vs 0.28±0.06, P=0.015). Conclusions: Methylation of DLC-1 gene is common in MDS patients and may be associated with poor prognosis. Decitabine may activate the expression of DLC-1 gene by demethylation, which may be one of the mechanisms for the treatment of patients with MDS.

Abstract
Objective: To analyze the bone mineral density and serum osteocalcin levels in postmenopausal women with idiopathic benign paroxysmal positional vertigo. Methods: A total of 64 postmenopausal women with idiopathic BPPV were selected as the study group, and 98 postmenopausal healthy women were selected as the control group. Bone mineral density and serum osteocalcin levels were analyzed and compared between the groups.χ(2) test was used for numeration data and t test was used for measurement data. Results: The prevalence of osteoporosis or osteopenia in BPPV group 67.2% (43/64) was significantly higher than that in the control group 51.0% (50/98) (χ(2)=4.139, P=0.042). Among BPPV subjects, there was a negative correlation between osteocalcin and bone density T (r=-0.469, P<0.001). Osteocalcin was found in normal bone mass subgroup (13.61±4.32)μg/L, decreased bone mass subgroup (17.49±7.61)μg/L, and osteoporosis subgroup (20.83±6.72)μg/L, respectively, and the difference was statistically significant (F=5.39, P=0.007). Conclusions: Bone mineral density in BPPV group is lower than that in control group. The lower the bone mineral density of the patients, the higher the osteocalcin in BPPV group.

Abstract
Background Although percutaneous trigger digit release is common, controversy exists regarding its safety. The purpose of this study was to evaluate the feasibility and safety of the neurovascular displacement by local hydraulic dilatation (LHD) during percutaneous trigger digit release. Material/Methods Ten cadaver hands with 50 digits were dissected in this anatomical study. The distance between bilateral neurovascular bundles in each digit was measured before LHD and after LHD. The difference between the measured data before LHD and those after LHD in the same digit was compared to assess the feasibility of the neurovascular displacement by LHD. A further 81 patients with 106 trigger digits were treated by percutaneous release with neurovascular displacement by LHD in our clinical series. All patients were followed for 12 months. During the follow-up period, the presence of any postoperative complication and patient satisfaction were recorded. Results In our anatomical study, there was a statistically significant difference (p<0.05) comparing the average distance of bilateral neurovascular bundles before LHD with that after LHD. In the current series, no complications, such as digital neurovascular injury or recurrence of trigger, were encountered. On subjective assessment, 80/81 patients (98.8%) with 105/106 digits (99.1%) were graded as satisfactory with complete resolution of symptoms by percutaneous release under LHD. Conclusions Based on our study anatomical and clinical results, the neurovascular displacement by LHD may be a feasible adjunctive technique that may play a role in increasing the safety of percutaneous trigger digit release.

Abstract
Due to the introduction of newer, more efficacious treatment options, there is a pressing need for policy makers and public health officials to develop or adapt national hepatitis C virus (HCV) control strategies to the changing epidemiological landscape. To do so, detailed, country-specific data are needed to characterize the burden of chronic HCV infection. In this study of 17 countries, a literature review of published and unpublished data on HCV prevalence, viraemia, genotype, age and gender distribution, liver transplants and diagnosis and treatment rates was conducted, and inputs were validated by expert consensus in each country. Viraemic prevalence in this study ranged from 0.2% in Hong Kong to 2.4% in Taiwan, while the largest viraemic populations were in Nigeria (2 597 000 cases) and Taiwan (569 000 cases). Diagnosis, treatment and liver transplant rates varied widely across the countries included in this analysis, as did the availability of reliable data. Addressing data gaps will be critical for the development of future strategies to manage and minimize the disease burden of hepatitis C.

Abstract
Factors influencing the morbidity and mortality associated with viremic hepatitis C virus (HCV) infection change over time and place, making it difficult to compare reported estimates. Models were developed for 17 countries (Bahrain, Bulgaria, Cameroon, Colombia, Croatia, Dominican Republic, Ethiopia, Ghana, Hong Kong, Jordan, Kazakhstan, Malaysia, Morocco, Nigeria, Qatar and Taiwan) to quantify and characterize the viremic population as well as forecast the changes in the infected population and the corresponding disease burden from 2015 to 2030. Model inputs were agreed upon through expert consensus, and a standardized methodology was followed to allow for comparison across countries. The viremic prevalence is expected to remain constant or decline in all but four countries (Ethiopia, Ghana, Jordan and Oman); however, HCV-related morbidity and mortality will increase in all countries except Qatar and Taiwan. In Qatar, the high-treatment rate will contribute to a reduction in total cases and HCV-related morbidity by 2030. In the remaining countries, however, the current treatment paradigm will be insufficient to achieve large reductions in HCV-related morbidity and mortality.

Abstract
The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 17 countries in Africa, Asia, Europe, Latin America and the Middle East, and interventions for achieving the Global Health Sector Strategy on viral hepatitis targets-"WHO Targets" (65% reduction in HCV-related deaths, 90% reduction in new infections and 90% of infections diagnosed by 2030) were considered. Scaling up treatment and diagnosis rates over time would be required to achieve these targets in all but one country, even with the introduction of high SVR therapies. The scenarios developed to achieve the WHO Targets in all countries studied assumed the implementation of national policies to prevent new infections and to diagnose current infections through screening.

Abstract
The periodontal probe is the gold standard tool for periodontal examinations, including probing depth measurements, but is limited by systematic and random errors. Here, we used photoacoustic ultrasound for high-spatial resolution imaging of probing depths. Specific contrast from dental pockets was achieved with food-grade cuttlefish ink as a contrast medium. Here, 39 porcine teeth (12 teeth with artificially deeper pockets) were treated with the contrast agent, and the probing depths were measured with novel photoacoustic imaging and a Williams periodontal probe. There were statistically significant differences between the 2 measurement approaches for distal, lingual, and buccal sites but not mesial. Bland-Altman analysis revealed that all bias values were < ±0.25 mm, and the coefficients of variation for 5 replicates were <11%. The photoacoustic imaging approach also offered 0.01-mm precision and could cover the entire pocket, as opposed to the probe-based approach, which is limited to only a few sites. This report is the first to use photoacoustic imaging for probing depth measurements with potential implications to the dental field, including tools for automated dental examinations or noninvasive examinations.

Abstract
New results are reported from the operation of the PICO-60 dark matter detector, a bubble chamber filled with 52 kg of C_{3}F_{8} located in the SNOLAB underground laboratory. As in previous PICO bubble chambers, PICO-60 C_{3}F_{8} exhibits excellent electron recoil and alpha decay rejection, and the observed multiple-scattering neutron rate indicates a single-scatter neutron background of less than one event per month. A blind analysis of an efficiency-corrected 1167-kg day exposure at a 3.3-keV thermodynamic threshold reveals no single-scattering nuclear recoil candidates, consistent with the predicted background. These results set the most stringent direct-detection constraint to date on the weakly interacting massive particle (WIMP)-proton spin-dependent cross section at 3.4×10^{-41} cm^{2} for a 30-GeV c^{-2} WIMP, more than 1 order of magnitude improvement from previous PICO results.

Abstract
Objective:To investigate the correlation between the levels of cochlear hydrops with the clinic classification of Meniere's disease(MD).Method:3D-FlAIR MRI was performed 24 hours after intratympanic injection of 8-fold diluted Gadopentetate Dimeglumine in 31 patients with unilateral MD. We evaluated the levels of cochlear hydrops and further analyzed the correlation between the levels of cochlear hydrops and thresholds of pure tone audiometry and clinic classification of MD. Result:MRI image clearly distinguished perilymph from endolymph in the labyrinth. The images showed different levels of enhancement of perilymphatic fluid spaces. In the 31 patients, obvious signs of endolymphatic hydrops were found, including 4 cases of level 0, 6 cases of level 1, 11 cases of level 2 and 10 cases of level 3. Their average hearing threshold was(54.37±3.88)dB HL. The levels of cochlear hydrops were significantly correlated with pure tone audiometry thresholds (r=0.636,P<0.01) and MD classification(r=0.516,P<0.01). None of the patients after intratympanic injection complained about discomfort or happened with any complications such as eardrum perforation, infection, and so on. Conclusion:The degree of endolymphatic hydrops based on MRI in MD patient has significant correlation with the pure tone audiometry and classification of disease. The examination can act as an objective index for MD diagnosis.

Abstract
Worldwide, some 240 million people have chronic hepatitis B virus (HBV), with the highest rates of infection in Africa and Asia. Our understanding of the natural history of HBV infection and the potential for therapy of the resultant disease is continuously improving. New data have become available since the previous APASL guidelines for management of HBV infection were published in 2012. The objective of this manuscript is to update the recommendations for the optimal management of chronic HBV infection. The 2015 guidelines were developed by a panel of Asian experts chosen by the APASL. The clinical practice guidelines are based on evidence from existing publications or, if evidence was unavailable, on the experts' personal experience and opinion after deliberations. Manuscripts and abstracts of important meetings published through January 2015 have been evaluated. This guideline covers the full spectrum of care of patients infected with hepatitis B, including new terminology, natural history, screening, vaccination, counseling, diagnosis, assessment of the stage of liver disease, the indications, timing, choice and duration of single or combination of antiviral drugs, screening for HCC, management in special situations like childhood, pregnancy, coinfections, renal impairment and pre- and post-liver transplant, and policy guidelines. However, areas of uncertainty still exist, and clinicians, patients, and public health authorities must therefore continue to make choices on the basis of the evolving evidence. The final clinical practice guidelines and recommendations are presented here, along with the relevant background information.

Abstract
Cotton (Gossypium spp) is one of the most economically important crops that provide the world's most widely used natural fiber. Diseases such as Fusarium wilt and particularly Verticillium wilt seriously affect cotton production, and thus breeding for disease resistance is one of the most important goals of cotton breeding programs. Currently, potential exists to improve disease resistance in cultivated cotton. Increasing the understanding of the distribution, structure, and organization of genes or quantitative trait loci for disease resistance will help the breeders improve crop yield even in the event of disease. To facilitate the mapping of disease-resistance quantitative trait loci to achieve disease-resistant molecular breeding in cotton, it is necessary to develop polymorphic molecular markers. The objective of this study was to develop simple sequence repeat markers based on cotton expressed sequence tags for disease resistance. The efficacy of these simple sequence repeat markers, their polymorphisms, and cross-species transferability were evaluated. Their value was further investigated based on genetic diversity and evolution analysis. In this study, the unique sequences used to develop markers were compared with the G. arboretum and G. raimondii genome sequences to investigate their position, homology, and collinearity between G. arboretum and G. raimondii.

Abstract
Most prostate cancers (PCas) are classified as acinar type (conventional) adenocarcinoma which are composed of tumor cells with luminal differentiation including the expression of androgen receptor (AR) and prostate-specific antigen (PSA). There are also scattered neuroendocrine (NE) cells in every case of adenocarcinoma. The NE cells are quiesecent, do not express AR or PSA, and their function remains unclear. We have demonstrated that IL8-CXCR2-P53 pathway provides a growth-inhibitory signal and keeps the NE cells in benign prostate and adenocarcinoma quiescent. Interestingly, some patients with a history of adenocarcinoma recur with small cell neuroendocrine carcinoma (SCNC) after hormonal therapy, and such tumors are composed of pure NE cells that are highly proliferative and aggressive, due to P53 mutation and inactivation of the IL8-CXCR2-P53 pathway. The incidence of SCNC will likely increase due to the widespread use of novel drugs that further inhibit AR function or intratumoral androgen synthesis. A phase II trial has demonstrated that platinum-based chemotherapy may be useful for such therapy-induced tumors.

Abstract
Zhuang ethnic minority is the largest minority group in China. Here, we report for the first time the polymorphisms of MICA and MICB in a healthy Zhuang population of 209 unrelated individuals. Using polymerase chain reaction-sequence specific priming (PCR-SSP) and sequencing-based typing (PCR-SBT), 13 MICA-sequence alleles and 5 MICA-STR alleles, as well as 11 MICB alleles were detected, among which MICA(∗)010, MICA(∗)A5 and MICB(∗)005:02 were the most frequent alleles. Linkage disequilibria was investigated and the most common two-locus haplotypes were MICB(∗)005:02-MICA(∗)010 and MICB(∗)014-MICA(∗)045. These results suggest informative genetic markers for investigating origins and evolution of MHC class I region haplotypes in Zhuang population.

Abstract
Hylocereus undatus widely grows in southern China. Some varieties are planted for their fruits, known as dragon fruits or Pitaya, while some varieties for their flowers known as Bawanghua. Fresh or dried flowers of Bawanghua are used as routine Chinese medicinal food. Since 2008, a serious anthracnose disease has led to great losses on Bawanghua flower production farms in the Baiyun district of Guangzhou city in China. Anthracnose symptoms on young stems of Bawanghua are reddish-brown, sunken lesions with pink masses of spores in the center. The lesions expand rapidly in the field or in storage, and may coalesce in the warm and wet environment in spring and summer in Guangzhou. Fewer flowers develop on infected stems than on healthy ones. The fungus overwinters in infected debris in the soil. The disease caused a loss of up to 50% on Bawanghua. Putative pathogenic fungi with whitish-orange colonies were isolated from a small piece of tissue (3 × 3 mm) cut from a lesion margin and cultured on potato dextrose agar in a growth chamber at 25°C, 80% RH. Dark colonies with acervuli bearing pinkish conidial masses formed 14 days later. Single celled conidia were 11 to 18 × 4 to 6 μm. Based on these morphological characteristics, the fungi were identified as Colletotrichum gloeosporioides (Penz.) Penz. & Sacc (2). To confirm this, DNA was extracted from isolate BWH1 and multilocus analyses were completed with DNA sequence data generated from partial ITS region of nrDNA, actin (ACT) and glutamine synthetase (GS) nucleotide sequences by PCR, with C. gloeosporioides specific primers as ITS4 (5'-TCCTCCGCTTATTGATATGC-3') / CgInt (5'-GGCCTCCCGCCTCCGGGCGG-3'), GS-F (5'-ATGGCCGAGTACATCTGG-3') / GS-R (5'-GAACCGTCGAAGTTCCAC-3') and actin-R (5'-ATGTGCAAGGCCGGTTTCGC-3') / actin-F (5'-TACGAGTCCTTCTGGCCCAT-3'). The sequence alignment results indicated that the obtained partial ITS sequence of 468 bp (GenBank Accession No. KF051997), actin sequence of 282 bp (KF712382), and GS sequence of 1,021 bp (KF719176) are 99%, 96%, and 95% identical to JQ676185.1 for partial ITS, FJ907430 for ACT, and FJ972589 for GS of C. gloeosporioides previously deposited, respectively. For testing its pathogenicity, 20 μl of conidia suspension (1 × 106 conidia/ml) using sterile distilled water (SDW) was inoculated into artificial wounds on six healthy young stems of Bawanghua using sterile fine-syringe needle. Meanwhile, 20 μl of SDW was inoculated on six healthy stems as a control. The inoculated stems were kept at 25°C, about 90% relative humidity. Three independent experiments were carried out. Reddish-brown lesions formed after 10 days, on 100% stems (18 in total) inoculated by C. gloeosporioides, while no lesion formed on any control. The pathogen was successfully re-isolated from the inoculated stem lesions on Bawanghua. Thus, Koch's postulates were fulfilled. Colletotrichum anthracnose has been reported on Pitaya in Japan (3), Malaysia (1) and in Brazil (4). To our knowledge, this is the first report of anthracnose disease caused by C. gloeosporioides on young stems of Bawanghua (H. undatus) in China. References: (1) M. Masyahit et al. Am. J. Appl.

Abstract
Cytochrome P450 enzymes play a major role in the metabolism of several of the chemical carcinogens involved in the development of hepatocellular carcinoma (HCC). To investigate by immunohistochemistry interindividual differences in these enzymes, polyclonal antisera and immunoperoxidase staining were used to detect the expression of CYP1A1/2 and 3A4 in 37 surgical control tissues and 105 tumour and adjacent nontumour tissues of HCC cases from Taiwan. There was variability in the expression and staining pattern for both CYP1A1/2 and 3A4 in all tissue types. In tissues from controls, there was no correlation between P450 expression and smoking history or hepatitis B virus antigen status. Since these samples had been previously analysed for the DNA adducts of aflatoxin B1 (AFB1), a dietary mould contaminant, and 4-aminobiphenyl (4-ABP), a component of cigarette smoke, we also investigated the relationship between P450 levels and DNA adducts. 4-ABP-DNA adducts were higher in tissues with elevated levels of CYP1A1/2 (p = 0.02). Overall there was no relationship between CYP1A1/2 or CYP3A4 and AFB1-DNA adducts in control tissues. Staining intensity for CYP1A1/2 and 3A4 followed the order: tumour tissues < control tissues < adjacent non-tumour tissues. CYP1A1/2 levels tended to be lower in tumour and adjacent non-tumour tissues than for CYP3A4. In HCC cases, 4-ABP-DNA adducts were higher in subjects with higher levels of CYP1A1/2, stratified by tissue type, but these differences were not significant. For CYP3A4, in contrast to control tissues, there was a significant association with AFB1-DNA adducts in tumour and adjacent non-tumour tissue of HCC cases. These results suggest that one factor influencing carcinogen-DNA adducts is levels of specific P450 enzymes. However, adduct formation in vivo is a complex processes dependent upon numerous genetic and environmental factors.

Abstract
We assessed the efficacy of loratadine syrup compared with cyproheptadine HCl solution for treating children aged from 2 to 12 years with perennial allergic rhinitis (PAR) in Taiwan. Sixty children with mite-induced PAR were enrolled and randomly placed into two treatment groups: loratadine syrup or cyproheptadine HCl solution. Treatment efficacy and symptom changes from baseline to post-treatment were evaluated by total symptom scores and visual analogue scales (VAS) during a 2-week period. There were no differences in age, gender, height, or weight between the two groups. After 2 weeks of treatment, there was a significantly greater reduction in symptom scores in the loratadine group than in the cyproheptadine group (p<0.001). Clinical and subjective VAS showed significant differences in percentage changes from baseline between the loratadine and cyproheptadine groups at all time points (all p<0.001, in favor of loratadine). Clinical VAS change at week 1: 95.1 vs 11.3; subjective VAS change at week 1: 88.6 vs 13.6; clinical VAS change at week 2: 125.5 vs 18.3; subjective VAS change at week 2: 101.4 vs 7.1. Thus, loratadine was superior to cyproheptadine for alleviating both nasal and non-nasal symptoms of perennial allergic rhinitis in Taiwanese children aged 2-12 years.

Abstract
AIMS The combined treatment of peripheral nerve (PN) graft and fibroblast growth factor (FGF)-1 for spinal cord injury produces functional recovery, but how it affects injury events is still unknown. This project studied the effect of PN graft and FGF-1 on white matter degeneration following spinal cord injury. METHODS Rats were divided into four groups: (i) complete spinal cord transection and T8 segment removed; the remaining three groups underwent transection followed by (ii) PN grafting; (iii) supply of exogenous FGF-1; and (iv) PN grafting plus FGF-1 treatment. Chondroitin sulphate proteoglycan (CSPG) deposition, astrocytes and macrophage activation, cavity size, and calcitonin gene-related peptide and synaptophysin immunoreactivity were compared. RESULTS Peripheral nerve grafting increased CSPG levels compared to transection surgery alone. This CSPG was associated with the proximity to the PN graft. FGF-1 reduced CSPG deposition in grafted animals regardless of the proximity to the graft. The CSPG reduction was accompanied by reduced GFAP expression and macrophage activation. The amount of CSPG with dissociated glycosaminoglycan did not differ between groups. FGF-1 in Schwann cell-astrocyte coculture did not reduce CSPG deposition. Furthermore, the PN graft increased the calcitonin gene-related peptide immunoreactivity and altered the distribution of synaptophysin-positive axons. CONCLUSION Peripheral nerve graft supported sensory re-innervation and partial protection of the grey matter, but up-regulated CSPG in the graft-stump junction compared to non-grafted rats. The reduction of CSPG was caused by FGF-1-PN synergy, and did not involve dissociation of CSPG or the suppression of a general immune response.

Abstract
Background: To determine whether non-viral nasopharyngeal carcinoma (NPC) risk factors might be associated with (and mediated through) Epstein–Barr virus (EBV) serological responses linked to NPC risk, we evaluated predictors of risk of anti-EBNA1 IgA seropositivity and other markers among unaffected relatives from a large NPC family study in Taiwan. Methods: Multivariate logistic regression conditioned on family was used to examine the associations between sociodemographic, dietary, lifestyle, and occupational variables and risk of anti-EBV EBNA1 IgA positivity, anti-VCA IgA, and anti-DNase positivity. Results: Among 2393 unaffected relatives from 319 multiplex families, 1180 (49.3%) were anti-EBV EBNA1 IgA seropositive. None of the associations with anti-EBNA1 IgA were statistically significant, except for being 31–50 years of age (vs <30, adjusted ORs 0.51–0.57). For one or more EBV serological markers, there were suggestive associations for older age, GuangDong firm salted fish, betel use, current alcohol use, and male gender. Conclusion: Overall, we found little evidence to suggest that non-viral NPC risk factors significantly alter EBV serological patterns, suggesting that non-viral NPC risk factors act through pathways independent of EBV serological responses.

Abstract
BACKGROUND The evidence for a role of tobacco smoking, alcohol drinking, and body mass index (BMI) in the etiology of small intestine cancer is based mainly on case-control studies from Europe and United States. SUBJECTS AND METHODS We harmonized the data across 12 cohort studies from mainland China, Japan, Korea, Singapore, and Taiwan, comprising over 500,000 subjects followed for an average of 10.6 years. We calculated hazard ratios (HRs) for BMI and (only among men) tobacco smoking and alcohol drinking. RESULTS A total of 134 incident cases were observed (49 adenocarcinoma, 11 carcinoid, 46 other histologic types, and 28 of unknown histology). There was a statistically non-significant trend toward increased HR in subjects with high BMI [HR for BMI>27.5 kg/m2, compared with 22.6-25.0, 1.50; 95% confidence interval (CI) 0.76-2.96]. No association was suggested for tobacco smoking; men drinking>400 g of ethanol per week had an HR of 1.57 (95% CI 0.66-3.70), compared with abstainers. CONCLUSIONS Our study supports the hypothesis that elevated BMI may be a risk factor for small intestine cancer. An etiologic role of alcohol drinking was suggested. Our results reinforce the existing evidence that the epidemiology of small intestine cancer resembles that of colorectal cancer.

Abstract
BACKGROUND To establish a pigmentation spot model on human skin and to assess whitening efficacy for whitening products by this established pigmentation spot model. METHODS Twenty subjects between 20 and 45 years old with skin phototype III or IV were selected. Three consecutive daily UV exposures were performed on buttocks of the subjects as follows: Day 1=1 minimal erythema dose (MED), Day 2=0.5 MED and Day 3=0.5 MED. After the first UV exposure, a selected whitening product was applied to the subjects twice a day on UV exposure area. The application of the whitening product to subjects on the exposed areas was continued till Day 27. CM2500d chromameter, Maxmeter MX18 and visual evaluation were used to assess changes of skin color. RESULTS A pigmentation spot model after UV exposure was established. The measurement of the pigment spot showed that L* value declined abruptly at Day 3 and then slowly reached to a lowest point at Day 6. L* value of the pigment spot almost remained at the same level until Day 20, thereafter increased slowly. The a* value showed an abrupt increase at Day 3 and slowly reached to a maximal level at Day 6. The a* value slowly declined toward its baseline level. Likewise, the erythema index also increased significantly at Day 3, and reached to a maximal level at Day 6 and then slowly declined. However, L*, a* and erythema indices did not return to their baseline levels during the 27-day period of this study. On the other hand, b* value started to increase from Day 3 and such increase was observed continuously to Day 27. Melanin index also showed a slow increase during the first 3 days. It started to increase rapidly from Day 3 and a to maximal level at Day 9 and maintain at a plateau till Day 27 (with an exception at Day 13). To assess the whitening product by this pigmentation spot model, DeltaL, Deltab*, and DeltaM values were analyzed. It showed that absolute DeltaL value and Deltab*value of whitening products were lower than those values of the vehicle of the whitening product at each checkpoint, while DeltaM value of the whitening product was lower only at Day 9 and Day 20, although no statistically significant differences was found. The visual results also strongly supported that the whitening product enhanced the decrease of pigmentation. CONCLUSION This study showed that repeated UV exposure was able to induce a long extensive period of pigment formation. The resulted pigmentation spot was able to maintain at an elevated level till Day 20. Clinical subjective evaluations together with combined objective instrument measurements were still important to assess whitening and spot-removing ability of a material due to the instrument limitation for color differentiations. This kind of pigmentation spot model can be used to assess whitening efficacy for whitening or spot-removing products. In addition, the combinations of subjective and objective methods were able to serve as advisable references to assess the whitening efficacy of products.

Abstract
It has been demonstrated that endogenous kidney dopamine (DA) contributes to the natriuretic response to acute volume expansion (VE). Several studies suggest that a defect in renal DA-ergic mechanism may play a role in genetic hypertension in humans and rats. The present study was designed to determine the role of renal DA and tubular DA-1 receptors in the natriuretic response to VE in age-matched spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats of 10-12 weeks of age. In pentobarbital-anesthetized rats, VE was carried out by intravenously infusing isotonic sodium chloride (5% body weight) over a period of 60 min. This maneuver evoked pronounced increases in urine output, urinary sodium excretion and urinary DA excretion. However, the natriuretic and diuretic response to VE was significantly reduced in SHR, although the increase in urinary DA excretion was similar in both SHR and WKY rats. During VE no significant changes in glomerular filtration rate or blood pressure were noted in either strain of animals, indicating the involvement of renal tubular mechanisms in the natriuretic response. In a separate group of SHR and WKY rats, pretreatment with DA-1 receptor antagonist SCH 23390 caused significant attenuation of the natriuretic and diuretic response to VE in WKY rats but not in SHR, suggesting that unlike WKY rats kidney DA was not contributing to the natriuretic response to VE in SHR. In another group of animals, the renal effects of exogenously administered DA-1 receptor agonist fenoldopam were examined. Fenoldopam (1 microgram/kg/min) produced significant increases in urine output and urinary sodium excretion without causing any alterations in blood pressure or glomerular filtration rate in both SHR and WKY rats. However, the interesting observation was that fenoldopam-induced diuresis and natriuresis were significantly attenuated in SHR compared to the WKY rats. These results show that SHR are not able to eliminate an acute increase in sodium load as efficiently as WKY rats, which may be at least in part due to a defect in renal tubular DA-1 receptor function.
