Abstract
Objective The objective of this study was to explore factors that impact functional coronary artery ischemia (FCAI) and develop a gender-specific prognostic model that could serve as a benchmark for predicting FCAI in clinical practice. Methods A cumulative total of 330 patients were enrolled comprising 634 main and branch coronary, consisting of 179 men (359 coronary arteries) and 151 women (275 coronary arteries). Based on the computed tomography-fractional flow reserve (CT-FFR), the coronary arteries of male and female patients were classified into the non-ischemic group (CT-FFR ≥ 0.80) and the ischemic group (CT-FFR < 0.80). We screened for factors related to the CT-FFR values of the coronary arteries in male and female patients and developed corresponding gender-specific models. Results In male patients, the correlation between FCAI and several indicators, including white blood cell (WBC) count, left anterior descending artery (LAD) lesions, pericoronary fat attenuation index (FAI), and the degree of coronary artery stenosis, was found to be statistically significant. A predictive model was developed using these factors, yielding an area under the curve (AUC) value of 0.812, with a P value of < 0.001 and a 95% confidence interval (CI) ranging from 0.767 to 0.857. This model demonstrated superior predictive capability compared to any individual indicators mentioned above. Significant correlations with FCAI were observed in female patients for hemoglobin (Hb), systolic blood pressure (SBP), FAI, and the degree of coronary artery stenosis. The predictive model, derived from these factors, exhibited robust performance with an area under the curve (AUC) value of 0.818, a P value of < 0.001, and a 95% confidence interval (CI) ranging from 0.764 to 0.872. Conclusion Gender disparities exist in the factors affecting FCAI, underscoring the need for a gender-specific predictive model to enhance the precision of FCAI prediction.

Abstract
Objective: To investigate the associations of cardiometabolic multimorbidity (CMM) with grip strength and gait speed among older Chinese adults. Methods: This study included participants aged ≥60 years from the China Health and Retirement Longitudinal Survey during 2011-2015. Generalized estimating equation models were employed to estimate the associations of CMM with grip strength and gait speed. Results: A total of 6 357 participants were included to measure grip strength and 6 250 participants to measure gait speed. Compared with no cardiometabolic disease, participants with 1 (β=-0.018, 95%CI: -0.026--0.010), 2 (β=-0.029, 95%CI: -0.041- -0.018), and ≥3 (β=-0.050, 95%CI: -0.063- -0.037) cardiometabolic diseases were associated with a decreased grip strength. The associations between cardiometabolic disease counts (1: β=-0.052, 95%CI: -0.326-0.222; 2: β=-0.083, 95%CI: -0.506-0.340; ≥3: β=-0.186, 95%CI: -0.730-0.358) and gait speed were not statistically significant. The predictive value of gait speed of the participants with 0, 1, 2, and ≥3 cardiometabolic diseases were found to be 1.98 (95%CI: 1.38-2.58), 1.93 (95%CI: 1.34-2.51), 1.89 (95%CI: 1.18-2.61), and 1.79 (95%CI: 1.10-2.48) m/s respectively, which was clinically significant for the magnitude of the decrease. Cardiometabolic combinations with a higher risk of decreased grip strength and gait speed mainly seen in diabetes. Conclusions: Cardiometabolic disease counts and combinations were associated with grip strength and gait speed. Grip strength and gait speed can be used to measure CMM severity.

Abstract
AIM The aim of our systematic review and meta-analysis was to assess the risk of postpolypectomy bleeding (PPB) in patients exposed to direct oral anticoagulants (DOACs). METHODS A systematic search was conducted by searching the PubMed, Embase, and Cochrane Library databases using the following search terms: "(nonvitamin K antagonist oral anticoagulants or NOAC or apixaban or dabigatran or rivaroxaban or edoxaban or DOAC or direct oral anticoagulants) and polypectomy". Studies evaluating the association between DOACs and PPB were identified. RESULTS The bibliographical search yielded 103 studies. Twelve studies involving 621,279 participants were ultimately included (11 cohort studies, of which 10 were retrospective, and a randomized controlled trial.). Pooled estimates revealed a higher risk of PPB among patients using DOACs than among those without anticoagulation (odds ratio [OR]: 6.170, 95% confidence interval [CI]: 3.079 to 12.363). The same result occurred when DOACs were stopped 24 hours before polypectomy (OR: 8.66, 95% CI: 4.588 to 16.348). No significant difference was noted between overall DOACs and warfarin (OR 0.826, 95% CI 0.583 to 1.172), while for subgroups, dabigatran showed a lower PPB rate than warfarin (OR: 0.582, 95% CI: 0.340 to 0.994). CONCLUSIONS DOACs can significantly raise the risk of PPB, even with 24-hour withdrawal before polypectomy. In addition, a lower risk of PPB was detected for dabigatran than for warfarin.

Abstract
Objective: To compare the efficacy of unilateral biportal endoscopy (UBE) and coaxial large channel endoscopy for lumbar spinal stenosis. Methods: A total of 176 patients with lumbar spinal stenosis treated in Tianjin Hospital from March 2015 to October 2021 were included in this study. Of the patients, 110 cases were treated with UBE, including 52 males and 58 females, with a mean age of (75.1±10.4) years; while 66 cases were treated with coaxial large channel endoscopy, including 31 males and 35 females, with an average age of (77.2±13.1) years. The visual analogue scale (VAS) score of pain and Oswestry disability index (ODI) were compared before and after surgery between the two groups, with the improvement rate calculated. The operation time, intraoperative blood loss, perioperative conditions and complications were compared. The operation efficacy was evaluated according to MacNab scale and was compared between the two groups. Results: There was no significant differences in age, gender, disease course, VAS of pain, ODI and index levels between the two groups before operation (all P>0.05). The operation time and postoperative drainage in UBE group and coaxial large channel endoscopy group were comparable [(60.1±12.4)min, (62.5±13.2)min and (103.8±20.7)ml, (98.5±22.1)ml, respectively, both P>0.05]. After the operation, the VAS score of low back pain, VAS score of leg pain and ODI of the two groups were all lower than those before operation, and decreased continuously during follow-up; and under the repeated measures analysis of variance, significant differences were found between different time points (all P<0.05), no significant difference was found between the two groups (all P>0.05), nor interaction between groups and time points was detected (all P>0.05). The patients were followed-up for (18.0±4.2) months (6 to 30 months). There was no significant difference in VAS and ODI improvement rates and excellent rate of efficacy between the two groups at the last follow-up (all P>0.05). Conclusions: Both UBE and coaxial large channel endoscopy can provide excellent results for lumbar spinal stenosis. UBE has sufficient decompression and is convenient to explore and remove the herniated disc.

Abstract
BACKGROUND Endometriosis affects approximately 10% of reproductive-age women, however, endometriosis associated malignant transformation is rare and is often report as a rare case.
CASE SUMMARY Herein, we report of a 49-year-old female patient who suffered from severe left lower abdominal pain and imaging examination revealed an irregular mass in the left iliac fossa. Histopathological examination revealed main undifferentiated adenocarcinoma with a few typical endometrial epithelial and stromal tissues in the adjacent area. Combined with the immunohistochemical staining and the negative intra- or postoperative results from exploratory laparotomy, gastroscopy, enteroscopy and positron emission tomography, the tumor was considered to be derived from endometriosis. The patient underwent hysterectomy, bilateral salpingectomy, bilateral ovariectomy, and multipoint biopsy of the pelvic peritoneum. Subsequent radiotherapy and chemotherapy were performed. The patient recovered well post-operation and there was no evidence of recurrence after 10 mo of follow-up via computed tomography and magnetic resonance imaging.
CONCLUSION This case highlights a rare presentation of mass-like extragonadal endometriosis associated malignant transformation in the pelvis. Endometriosis associated malignant transformation is rare and difficult to diagnose in clinical settings, with diagnoses depending on pathological results and the exclusion of metastasis from other organs. Fortunately, patients are often diagnosed at younger ages, as well as at early stages; thus they generally have relatively favorable prognoses.

Abstract
Here, we investigated the effects of straw returning combined with biochar application on summer maize yield and soil nitrous oxide (N2O) emissions, based on a field location trial in the Guanzhong Plain from 2019 to 2020. The soil N2O emission rates were monitored using the static chamber-chromatography method. A comprehensive analysis of summer maize yields, soil N2O emissions, and soil labile nitrogen components was conducted to clarify the effects of straw returning combined with biochar application on improving soil fertility, increasing summer maize yield, and reducing greenhouse gas emissions. The three treatments were no straw returning (S0), straw returning (S), and straw returning combined with biochar application (SB). The results showed that the peak of N2O emissions from each treatment occurred 10 d after the straw return, and the rate of soil N2O emissions remained at a low level after 30 d of straw return. The rate of soil N2O emissions showed highly significant positive correlations (P<0.05) with ammonium nitrogen (NH4+-N), inorganic nitrogen (SIN), microbial nitrogen (MBN), and dissolved organic nitrogen (DON) contents. S significantly increased summer maize yield, cumulative N2O emissions, yield-scaled N2O intensity, and total nitrogen (TN) content by 7.4%-13%, 65.8%-132.2%, 54.6%-103%, and 27.8%-33%, respectively, compared to those in S0. Although the trend for SB to increase summer maize yield (2.5%-3.3%) compared to that in S was not significant (P>0.05), SB significantly reduced cumulative N2O emissions and yield-scaled N2O intensity by 24.0%-27.3% and 26.4%-29.2%, respectively, compared to that in S. SB significantly reduced the rate of soil N2O emissions by 45.1%-69.6% at the peak of N2O emissions compared to that in S. Biochar application mitigated soil N2O emissions induced by straw return and had a peak-shaving effect. SB significantly increased soil total N by 9.1%-12.2% compared to that in S. Combining summer maize yield, soil N2O emissions, and TN content, SB not only improved soil fertility and summer maize yield but also reduced yield-scaled N2O intensity, making it a suitable management practice that can be replicated to balance crop yield and environmental friendliness.

Abstract
Objective: To explore the relationship between obesity status and death stratified by different multi-morbidity status in older adults in China. Methods: Data for older Chinese adults aged ≥65 years were from Chinese Longitudinal Healthy Longevity Survey (CLHLS). Multi-morbidity patterns based on 13 chronic conditions were explored using exploratory factor analysis. Cox models were used to examine relationships between obesity status and death stratified by disease count and multi-morbidity patterns at baseline, respectively. Besides, obesity status was defined by baseline body mass index and waist circumference. Results: A total of 6 272 participants were included in the analyses. Multi-morbidity including cardio-metabolic, sensory perception and other patterns were identified. For those without any chronic condition, compared with those without central obesity, central obesity was associated with a higher risk for death (HR=1.66, 95%CI:1.04-2.66). For those only with one chronic condition, compared with normal weight, underweight was associated with a higher risk for death (HR=1.41, 95%CI: 1.10-1.80). For those with multi-morbidity, compared with normal weight, underweight increased the risk for death (HR=1.19, 95%CI:1.05-1.34). Compared with those without central obesity, central obesity decreased the risk for death (HR=0.88, 95%CI:0.78-0.99). Conclusions: Relationships between obesity status and death varied by multi-morbidity status in older adults in China. Underweight and non-central obesity were associated with increased risks for death in older adults with only one chronic disease or multi-morbidity. Therefore, it is necessary to pay attention to multi-morbidity status in the management of obesity in older adults and provide effective targeted body weight management plan.

Abstract
Molecular dynamics (MD) simulation is used to study the corrosion inhibition mechanism of cysteine (Cys), glutamic (Glu) and glycine (Gly) for copper in hydrochloric acid solution. The adsorption energy and radial distribution function results show that all three amino acids can spontaneously adsorb on Cu (111) surface by chemical adsorption. The absolute value of adsorption energy and intensity is Cys > Glu > Gly. The diffusion coefficient and relative concentration curve show that all the three amino acids can inhibit the diffusion and aggregation ability of corrosion particles, so the three amino acids not only can slow down the aggregation of corrosive particles, but also effectively repel corrosive particles to protect the substrate. The inhibition ability obtained by the MD simulation shows the trend of Cys > Glu > Gly, which is consistent with the experimental results. The inhibition efficiency is determined by both the adsorption strength on the substrate surface and inhibition ability for the diffusion and aggregation ability of corrosion particles.

Abstract
OBJECTIVE To compare the femoral and tibial tunnel positions of anterior cruciate ligament reconstruction using the modified transtibial (MTT) technique and anteromedial (AM) portal technique. METHODS Between January 2017 and September 2020, 78 patients with anterior cruciate ligament rupture underwent single-bundle reconstruction with the modified transtibial technique in 39 cases (group MTT) and through anteromedial approach in 39 cases (group AM). There were 25 males and 14 females in group MTT, with an average age of (37.0±2.3) years old; 27 males and 12 females in group AM, with an average age of (37.5±2.2) years old. CT scan of the affected knee was conducted one week after the surgery to measure and compare the femoral tunnels positioning (Fx, Fy), tibial tunnels positioning in the frontal plane(Tx1), tibial tunnels positioning in the sagittal plane (Ty1), and tibial tunnels positioning in the axial plane (Tx2, Ty2) in patients undergoing anterior cruciate ligament reconstruction through Mimics software. RESULTS Three-dimensional CT reconstruction after the surgery showed that the average Fx and Fy were(25.2±2.1)% and (34.9±3.0)% respectively and the Tx1 and Ty1 were (45.5±3.3)% and (44.7± 3.0)% respectively, while the Tx2 and Ty2 were (47.0±3.0)% and (39.9±4.2)% respectively in group MTT. In group AM, the average Fx and Fy were (26.0±2.0)% and (36.1±3.9)% respectively and the Tx1 and Ty1 were (46.5±3.1)% and (45.6± 3.1)% respectively, while the Tx2 and Ty2 were (47.4±2.5)% and (39.6±3.9)% respectively. There were no statistically significant differences in the femoral and tibial tunnels between the two groups (P>0.05). Patients in both two groups obtained anatomic anterior cruciate ligament reconstruction. CONCLUSION Both the MTT and AM technique can achieve good anatomical positioning of the femoral and tibial tunnels, without significant differences in the positioning of the bone tunnels.

Abstract
In order to explore the impacts of nitrogen fertilizer and straw returning methods on N2O emissions, a two-factor split-zone design was adopted for experimentation under the winter wheat-summer maize rotation model in the Guanzhong area of Shanxi, China. The main areas of interest were conventional nitrogen (G) and reduced nitrogen (70% G); the sub-areas were straw no return (N), straw return (S), and straw return + biochar (SB); we analyzed their impacts on N2O emissions and crop yield, and the relationships with related impact factors. The results showed that the N2O emissions peaks appeared in the wheat season and maize season treatments within 5-16 days after fertilization, and also appeared after rainfall. The N2O flux was significantly and positively correlated with soil temperature and NH4+-N content. Regardless of the wheat season, maize season, or annual total N2O emissions, the 70% GSB treatment was the lowest and the GS treatment was the highest. At the same level of nitrogen application, S treatment increased N2O emissions, SB treatment could reduce N2O emissions, both S and SB treatments could significantly increase crop yields, and SB production increased more; 70%G-level annual N2O emissions, when compared with the G level, had been reduced by 40% to 48%, while the yield has not decreased significantly. Through comprehensive consideration, a reduction of nitrogen by 30% was achieved through the combination of straw + biochar on the basis of conventional nitrogen application, while ensuring high crop yields and the best N2O emissions reduction.

Abstract
BACKGROUND Esophageal schwannomas are uncommon esophageal submucosal benign tumors and are usually treated with surgery.
CASE SUMMARY Here, we report three cases of middle/lower thoracic esophageal schwannoma treated successfully with endoscopic resection. These lesions were misdiagnosed as leiomyoma on preoperative imaging. During the endoscopic resection of such tumors, there is a risk of esophageal perforation due to their deep location. If possible, submucosal tunneling endoscopic resection should be used.
CONCLUSION For larger schwannomas, endoscopy combined with thoracoscopy can be considered for en bloc resection. We performed a mini literature review in order to present the current status of diagnosis and treatment for esophageal schwannoma.

Abstract
Stiff limb syndrome (SLS) is a rare autoimmune-related central nervous system disorder, resulting in stiffness and spasms of limbs since onset with rare involvement of the truncal muscles. However, SLS patients will gain notable effects by appropriate therapy focusing on symptomatic treatment and immunotherapy. We reported on a 55-year-old female who showed typical painful spasms in both lower limbs and abduction of the right eyeball that partially responded to low-dose diazepam and had high-titer anti–glutamic acid decarboxylase (anti-GAD) antibody. Electromyography (EMG) only showed continuous motor unit activity (CMUA) in the anterior tibialis and right triceps. Eventually, our patient was diagnosed with SLS and treated with intravenous immunoglobulin (IVIG) and glucocorticoid combined simultaneously. She obtained notable effects. We also review and summarize the current literature on clinical characteristics, coexisting disease, treatment, and outcome of 40 patients with SLS. We hope that this report will provide a basis for further understanding of SLS and promote the formation of more advanced diagnosis and treatment processes.

Abstract
BACKGROUND The role of laparoscopically anatomical resection (LAR) for hepatocellular carcinoma (HCC) remains unclear due to the more demanding technique required in laparoscopy. This study is to analyze the clinical impact of LAR compared to laparoscopically non-anatomical resection (LNAR) for HCC. METHODS All patients received laparoscopic hepatectomy for HCC (diameter 5-10 cm) from January 2015 to December 2018 were retrospectively enrolled in this study. Patients were divided into LAR and LNAR groups. The perioperative and oncological outcomes were evaluated based on propensity score matching (PSM) method. RESULTS After PSM, 51 patients in each group were enrolled. The operative time in LAR group was longer (240 vs 195.0 min, p = 0.012) and blood loss was more (200.0 vs 150.0 mL, p = 0.030) than those of LNAR group, respectively. The total complication rates were comparable between them (21.6% vs 17.6%, p = 0.500). The 3-year overall survival rates were 59.4% in LAR group and 38.7% in LNAR group, respectively (p = 0.045). The 3-year disease-free survival rates were 52.3% in LAR group and 27.0% in LNAR group, respectively (p = 0.042). CONCLUSION LAR could be feasibly performed with comparable perioperative outcomes and contributed to improve long-term survival in patients with HCC (diameter 5-10 cm) when compared to LNAR.

Abstract
Abstract
Essential tremor is one of the most common movement disorders. Despite its high prevalence and heritability, the genetic aetiology of essential tremor remains elusive. Up to now, only a few genes/loci have been identified, but these genes have not been replicated in other essential tremor families or cohorts. Here we report a genetic study in a cohort of 197 Chinese pedigrees clinically diagnosed with essential tremor. Using a comprehensive strategy combining linkage analysis, whole-exome sequencing, long-read whole-genome sequencing, repeat-primed polymerase chain reaction and GC-rich polymerase chain reaction, we identified an abnormal GGC repeat expansion in the 5′ region of the NOTCH2NLC gene that co-segregated with disease in 11 essential tremor families (5.58%) from our cohort. Clinically, probands that had an abnormal GGC repeat expansion were found to have more severe tremor phenotypes, lower activities of daily living ability. Obvious genetic anticipation was also detected in these 11 essential tremor-positive families. These results indicate that abnormal GGC repeat expansion in the 5′ region of NOTCH2NLC gene is associated with essential tremor, and provide strong evidence that essential tremor is a family of diseases with high clinical and genetic heterogeneities.

Abstract
Background To compare the outcomes of submucosal tunneling endoscopic resection (STER) and submucosal excavation (ESE) for the treatment of submucosal tumors (SMTs) arising from the muscularis propria (MP) at the esophagogastric junction (EGJ). Methods A retrospective analysis of patients with SMTs at EGJ who underwent STER and ESE from October 2011 to October 2017 was performed. The outcomes evaluated were operation time, complete resection rate, adverse events, and tumor recurrence. Results Ninety patients were included in this study. Complete resection rates in the STER group were higher than those of the ESE group (100 vs. 92%, p < 0.05). For tumors ≤15 mm, both techniques achieved 100% complete resection rate; but for tumors > 15 mm, complete resection rate was higher in the STER group than the ESE group (100% vs. 77.8%, p < 0.05). Subgroup analyses revealed that the operation time of STER for in cardiac-gastric group was longer than that for ESE (145.14 ± 42.43 min vs. 70.32 ± 39.84 min, p < 0.05). The air leakage symptoms were more frequent in STER group (90.9% vs. 50.0%, p < 0.05). No tumor recurrence occurred in both the STER and ESE groups. Conclusions For SMTs ≤15 mm, both STER and ESE have similar satisfactory therapeutic outcomes. However, in the cardiac-gastric subgroup, STER had a longer operative time compared to the ESE procedure. For SMTs > 15 mm, STER is the preferred choice due to its higher complete resection rate.

Abstract
With the aim of studying the effects of different vegetation zones on soil aggregate stability and its stoichiometric characteristics, the soils under Robinia pseudoacacia plantations located within different vegetation zones on the Loess Plateau were selected as the research object. Indicators including the content, stoichiometry, and stability of different aggregate fractions were analyzed. The results showed that the content of >2 mm and 0.25-2 mm, the mean diameter (EMWD), and the geometric mean diameter (EGMD) of aggregate fractions were in the order of forest zone > forest-steppe zone > grassland zone. However, the stability proxies of aggregate fractions across the three vegetation zones indicated that the content and erodibility (K factor) of 0.053-0.25 mm exhibited an opposite trend. The overall trend of the soil organic carbon and total nitrogen of aggregate fractions among the three vegetation zones was that the forest zone significantly overtopped the forest-steppe zone and grassland zone, while the content of total phosphorus showed no significant differences among the three vegetation zones. Additionally, the content of soil organic carbon and total nitrogen of < 0.053 mm and 0.25-2 mm was the highest among the different fractions in the grassland zone, while that of 0.053-0.25 mm and 0.25-2 mm was the highest in the forest-steppe zone. In contrast, there were no significant differences in the content of organic carbon and total nitrogen in the forest zone among the different aggregate fractions. The total phosphorus content topped in < 0.053 mm fractions in the grassland zone and the forest-steppe zone, while that in the forest zone had no significant differences among the different aggregate fractions. Besides, the C:N ratios of < 0.053 mm and 0.053-0.25 mm in the steppe zone and the forest-steppe zone were higher than that in the forest zone, while that of 0.25-2 mm and >2 mm had insignificant differences among the three vegetation zones. The C:P and N:P ratios of fractions in the forest zone were significantly higher than that in the forest-steppe zone and steppe zone. Overall, the stability and stoichiometry of soil aggregate fractions exhibited relatively significant differences among the three vegetation zones. Additionally, the stability, soil organic carbon, and total nitrogen content of aggregate fractions in the forest zone were generally higher than those in the forest-steppe zone and grassland zone.

Abstract
OBJECTIVE The most potent vasoconstrictor, endothelin-1 and its receptors, endothelin receptor A (EDNRA) and endothelin receptor B (EDNRB) are involved in hypertension. Hypertension is a major risk factor of intracerebral hemorrhage (ICH). Recent studies have demonstrated increased plasma endothelin-1 level in ICH patients and relationships between EDNRA and EDNRB genetic variants and ischemic stroke. The aim of the current study was to investigate whether EDNRA and EDNRB polymorphisms are associated with ICH by interacting with blood pressure levels. METHODS Five EDNRA and EDNRB polymorphisms were genotyped in this case-control study. RESULTS We identified that EDNRA rs5333 T allele might be a protective factor of ICH (adjusted odds ratio [OR] = 0.638, 95% CI: 0.417-0.977, P = 0.038), while EDNRB rs5351 A allele could be a risk factor of ICH (adjusted OR = 1.476, 95% CI: 1.042-2.089, P = 0.028). Moreover, we only found that the GG genotype of EDNRA rs5335 had higher diastolic blood pressure than the GC + CC genotypes in ICH patients (91.69 ± 18.77 vs. 84.71 ± 21.48, P = 0.004). CONCLUSIONS These findings support the important role of EDNRA and EDNRB polymorphisms in ICH, and suggest that they do not interact with blood pressure levels on altering ICH risk.

Abstract
BACKGROUND Laparoscopic major hepatectomy (LMH) for hepatocellular carcinoma (HCC) in patients with cirrhosis remains controversial due to limited reports in the literature. This study analyzed the perioperative and oncological outcomes of LMH for HCC with cirrhosis compared with open major hepatectomy (OMH). METHODS A retrospective analysis of patients with cirrhosis who underwent major hepatectomy for HCC between January 2015 and January 2017 was performed. Patients were divided into the LMH group and the OMH group. Short-term and oncological outcomes were compared before and after 1:1 propensity score matching (PSM). RESULTS A total of 103 HCC patients who received major liver resection were enrolled. There were 36 (35.0%) patients in the LMH group and 67 (65.0%) patients in the OMH group. After 1:1 PSM, well-matched 32 patients in each group were evaluated. Significant differences were observed in operative time (median, 255 vs. 200 min, p < 0.001) and Pringle time (median, 50 vs. 30 min, p < 0.001) between two groups. The blood loss and transfusion requirement were comparable in two groups. The rate of overall postoperative complications did not differ between two groups, while the incidence of ascites in the LMH group was significantly less than OMH group (9.4 vs. 31.3%, p = 0.030). The oncological outcomes between the two groups were comparable with regard to 2-year overall survival (85.7 vs. 86.7%, p = 0.694) and disease-free survival (72.9 vs. 81.5%, p = 0.990), respectively. CONCLUSIONS LMH for HCC patients with liver cirrhosis showed comparable results in terms of postoperative morbidity and oncological outcomes compared with traditional open procedure. LMH may serve as a safe and feasible alternative for selected HCC patients with cirrhosis.

Abstract
OBJECTIVE To evaluate the outcome of Titanium Elastic intramedullary nailing(TEN) for the treatment of refracture of clavicle. METHODS From March 2010 to March 2016, 9 cases of clavicle fracture, postoperative re-fracture (plate broken before fracture healing, plate and screw pull out or refracture after fracture union and internal fixation removal) included 6 males and 3 females with a mean age of 38.6 years old ranging from 20 to 62 years old; 3 cases were sports injury, 5 cases were traffic injury, 1 case was severe injury. All cases were closed fractures, and 2 cases were multiple fractures. According to OTA(Orthopaedic Trauma Association classification), 2 cases were 06-A1, 1 case was 06-A2, 1 case was 06-A3, 2 cases were 06-B1, 2 cases were 06-B2, and 1 case was 06-B3. Among them, 4 cases were treated with AO titanium elastic intramedullary nail (TEN), and 5 cases of early internal fixation failure of clavicle fracture were treated with plate and screw internal fixation plus bone graft. The time of bone union, VAS score and Constant Shoulder Score were observed and recorded. RESULTS All incisions healed at stage I without infection. All 9 patients were followed up for a period of 14 months. All patients' implants were removed at 12 months after the second operation without refractures. The Constant score of shoulder joint was from 64 to 94 at 4 weeks after the second operation, 91 to 100 at 4 weeks after implants removal. The average bone healing time was 4.3 months from 3 to 6 months. The pain VAS score decreased significantly and the pain was relieved significantly. CONCLUSIONS Titanium elastic intramedullary nail (TEN) for the treatment of clavicle fracture after internal fixation of refracture patients can be achieved better outcomes, less trauma, good fracture healing, good postoperative recovery of shoulder joint function, but need to pay attention to the reasonable selection of patients.

Abstract
In the report, we describe a case of refractory benign esophageal strictures from esophageal cancer after an operation for the placement of three partially covered self-expanding metal stents (SEMSs), which were all embedded in the esophageal wall. Using the stent-in-stent technique, the three embedded SEMSs were successfully removed without significant complications. To the best of our knowledge, few cases of the successful removal of multiple embedded esophageal SEMSs have been reported in the literature. This case also highlights that the stent-in-stent technique is effective for removing multiple embedded esophageal SEMSs.

BACKGROUND Laparoscopic liver resection (LLR) for lesions adjacent to major vessels was still associated with difficulty and challenge. This study aimed to compare outcomes after LLR and open liver resection (OLR) of lesions adjacent to major vessels. MATERIALS AND METHODS A retrospective analysis of patients with hepatic tumors close to main or second branches of Glisson's tree, to the major hepatic vein, or to the inferior vena cava within 1 cm between January 2015 and January 2017 was performed based on the propensity score matching (PSM) method. Perioperative and oncological outcomes were then evaluated. RESULTS A total of 64 patients underwent LLR and 86 patients had OLR. After 1:1 PSM, well-matched 40 patients in each group were obtained. The operative time (240 versus 210 minutes, P = .012) in the LLR group was significantly longer than that in the OLR group, whereas blood loss (200 versus 400 mL, P = .003) was less in the laparoscopic group. The median hospital stay for LLR (6 versus 8 days, P = .032) was shorter than for the open procedure. No statistical differences was noted according to overall postoperative complications, but the OLR group tended to be vulnerable to more severe complications. For patients with hepatocellular carcinoma, the comparable oncological results in terms of 2-year overall survival (P = .898) and disease-free survival (P = .992) were observed. CONCLUSIONS LLR for tumors adjacent to major vessels appears to be feasible and safe in selected patients. LLR is associated with less blood loss, shorter hospital stay, and similar oncological outcomes compared with OLR.

Abstract
BACKGROUND Laparoscopic major hepatectomy (LMH) for hepatocellular carcinoma (HCC) in patients with cirrhosis remains controversial due to limited reports in the literature. This study analyzed the perioperative and oncological outcomes of LMH for HCC with cirrhosis compared with open major hepatectomy (OMH). METHODS A retrospective analysis of patients with cirrhosis who underwent major hepatectomy for HCC between January 2015 and January 2017 was performed. Patients were divided into the LMH group and the OMH group. Short-term and oncological outcomes were compared before and after 1:1 propensity score matching (PSM). RESULTS A total of 103 HCC patients who received major liver resection were enrolled. There were 36 (35.0%) patients in the LMH group and 67 (65.0%) patients in the OMH group. After 1:1 PSM, well-matched 32 patients in each group were evaluated. Significant differences were observed in operative time (median, 255 vs. 200 min, p < 0.001) and Pringle time (median, 50 vs. 30 min, p < 0.001) between two groups. The blood loss and transfusion requirement were comparable in two groups. The rate of overall postoperative complications did not differ between two groups, while the incidence of ascites in the LMH group was significantly less than OMH group (9.4 vs. 31.3%, p = 0.030). The oncological outcomes between the two groups were comparable with regard to 2-year overall survival (85.7 vs. 86.7%, p = 0.694) and disease-free survival (72.9 vs. 81.5%, p = 0.990), respectively. CONCLUSIONS LMH for HCC patients with liver cirrhosis showed comparable results in terms of postoperative morbidity and oncological outcomes compared with traditional open procedure. LMH may serve as a safe and feasible alternative for selected HCC patients with cirrhosis.

Abstract
Background Both inflammation and immunity are associated with the development of malignancy. The lymphocyte-to-monocyte ratio (LMR) has been confirmed as a prognostic factor for several malignant diseases. The purpose of our study was to analyze prognostic significance of preoperative LMR in hepatitis B virus (HBV)-related hepatocellular carcinoma after curative resection. Patients and methods A total of 253 patients with primary HBV-positive hepatocellular carcinoma who underwent a curative operation were enrolled in this retrospective study. The relationship between preoperative LMR and survival outcomes was analyzed through Kaplan–Meier curves and multivariate Cox regression analyses. Results Patients with a high LMR had a significantly higher mean overall survival than those with a low LMR (67 months vs 55 months, P=0.023), and high LMR remained significant for longer survival in the multivariate analysis (hazard ratio, 0.147; 95% confidence interval [CI]: 0.085–0.253; P=0.021). Furthermore, patients with a high LMR also had a higher median recurrence-free survival than those with a low LMR in univariate analyses (60 months vs 48 months, P=0.026) and multivariate analyses (hazard ratio, 0.317; 95% CI: 0.042–1.023; P=0.032). However, the survival benefit was limited to patients with advanced cancer. Conclusion LMR was confirmed as an independent prognostic biomarker for primary HBV-positive hepatocellular carcinoma after curative resection.

Abstract
OBJECTIVE To investigate the stability of internal fixation for femoral neck fracture(FNF) using two or three cannulated screws directed to different fracture lines, and to provide a theoretical basis for the clinical decision making. METHODS Fifteen fresh frozen human femur samples were selected and the FNF model was established with Pauwels angle of 30°, 50° and 70° respectively. The models were fixed with three or two cannulated screws, and their differences at tensile strength, subsidence, shear strength and composite displacement, gap distance, torsional angle and stiffness values of four types of femur were evaluated to identify their biomechanical stability. RESULTS With Pauwels angle of 30° and 50°, no statistical differences at the referenced outcomes were observed between two and three cannulated screw fixation for FNF(P>0.05). With the Pauwels angle of 70 °, three cannulated screws fixation were significantly superior to two cannulated screws fixation for FNF(P<0.05). Nevertheless, when Pauwels angle was 70°, three cannulated screws fixation turned out to be relative instable compared with Pauwels angle of 30° and 50°. CONCLUSIONS With Pauwels angle of 30° and 50°, two cannulated screws fixation was similarly stable as using three cannulated screws for FNF. Three cannulated screws fixation were obviously superior to two cannulated screws fixation when Pauwels angle was 70°, but the application of three cannulated screws could still be insufficiently stable when only such routine fixations were utilized. Therefore, Angle Stabilizing System or anti-sliding screws were needed to enhance the stability of FNF fixation.

Abstract
Transcriptome analysis of barley embryogenic callus from isolated microspore culture under salt stress uncovered a role of translation inhibition and selective activation of stress-specific proteins in cellular defense. Soil salinity is one of the major abiotic stresses which constrains the plant growth and reduces the productivity of field crops. In this study, it was observed that the salt stress in barley isolated microspore culture impacted not only on the quantity of embryogenic callus but also on the quality for later differentiation. The barley microspore-derived embryogenic callus, a transient intermediate form linked cells and plants, was employed for a global transcriptome analysis by RNA sequencing to provide new insights into the cellular adaptation or acclimation to stress. A total of 596 differentially expressed genes (DEGs) were identified, in which 123 DEGs were up-regulated and 473 DEGs were down-regulated in the embryogenic callus produced from microspore culture under salt stress as compared to the control conditions. KEGG pathway analysis identified 'translation' (27 DEGs; 12.56 %) as the largest group and followed by 'folding, sorting and degradation' (25 DEGs; 11.63 %) in 215 mapped metabolic pathways. The results of RNA-Seq data and quantitative real-time polymerase chain reaction validation showed that the genes related to translation regulation (such as eIF1A, RPLP0, RPLP2, VARS) were down-regulated to control general protein synthesis, and the genes related to endoplasmic reticulum stress response (such as small heat shock protein genes) were selectively up-regulated against protein denaturing during microspore embryogenesis under continuous salt stress. These transcriptional remodeling might affect the essential protein synthesis for the cell development to fulfill totipotency under salt stress.

Abstract
AIM To investigate the potential protective effect of exogenous recombinant interleukin-22 (rIL-22) on L-arginine-induced acute severe pancreatitis (SAP)-associated lung injury and the possible signaling pathway involved. METHODS Balb/c mice were injected intraperitoneally with L-arginine to induce SAP. Recombinant mouse IL-22 was then administered subcutaneously to mice. Serum amylase levels and myeloperoxidase (MPO) activity in the lung tissue were measured after the L-arginine administration. Histopathology of the pancreas and lung was evaluated by hematoxylin and eosin (HE) staining. Expression of B cell lymphoma/leukemia-2 (Bcl-2), Bcl-xL and IL-22RA1 mRNAs in the lung tissue was detected by real-time PCR. Expression and phosphorylation of STAT3 were analyzed by Western blot. RESULTS Serum amylase levels and MPO activity in the lung tissue in the SAP group were significantly higher than those in the normal control group (P < 0.05). In addition, the animals in the SAP group showed significant pancreatic and lung injuries. The expression of Bcl-2 and Bcl-xL mRNAs in the SAP group was decreased markedly, while the IL-22RA1 mRNA expression was increased significantly relative to the normal control group (P < 0.05). Pretreatment with PBS did not significantly affect the serum amylase levels, MPO activity or expression of Bcl-2, Bcl-xL or IL-22RA1 mRNA (P > 0.05). Moreover, no significant differences in the degrees of pancreatic and lung injuries were observed between the PBS and SAP groups. However, the serum amylase levels and lung tissue MPO activity in the rIL-22 group were significantly lower than those in the SAP group (P < 0.05), and the injuries in the pancreas and lung were also improved. Compared with the PBS group, rIL-22 stimulated the expression of Bcl-2, Bcl-xL and IL-22RA1 mRNAs in the lung (P < 0.05). In addition, the ratio of p-STAT3 to STAT3 protein in the rIL-22 group was significantly higher than that in the PBS group (P < 0.05). CONCLUSION Exogenous recombinant IL-22 protects mice against L-arginine-induced SAP-associated lung injury by enhancing the expression of anti-apoptosis genes through the STAT3 signaling pathway.

Abstract
BACKGROUND Inflammation and immunity have an important role in the development of cancer. The lymphocyte-to-monocyte ratio (LMR) has been shown to be of prognostic value in several malignant forms. The purpose of this study was to analyze the prognostic significance of preoperative LMR in post-curative resection of pancreatic adenocarcinoma. METHODS A total of 144 patients with primary pancreatic adenocarcinoma who underwent curative operation were enrolled in this retrospective study. The correlation between preoperative LMR and survival was analyzed using Kaplan-Meier curves and multivariate Cox regression analyses. RESULTS In the univariate analysis, an elevated preoperative LMR was significantly associated with an increased overall survival (OS) (19 months vs 12 months, P=0.000), and this result remained significant in the multivariate analysis (hazard ratio [HR]: 0.148; 95% confidence interval [CI]: 0.085-0.252; P=0.000). Furthermore, patients with high LMR also had higher median recurrence-free survival (RFS) than patients with low LMR in univariate (18 months vs 10 months, P=0.000) and multivariate analyses (HR: 0.148; 95% CI: 0.085-0.252; P=0.000). Subgroup analyses showed that both patients with stage III cancer and patients with stage I+II cancer can obtain OS and RFS benefits from high LMR. CONCLUSION LMR can be considered as an independent prognostic biomarker for operable pancreatic adenocarcinoma.

Abstract
AIM: To evaluate the efficacy of ursodeoxycholic acid (UDCA) as a chemotherapeutic agent for the treatment of hepatocellular carcinoma (HCC).
METHODS: BALB/c nude mice were randomized into four groups 24 h before subcutaneous injection of hepatocarcinoma BEL7402 cells suspended in phosphate buffered saline (PBS) into the right flank. The control group (n = 10) was fed a standard diet while treatment groups (n = 10 each) were fed a standard daily diet supplemented with different concentrations of UDCA (30, 50 and 70 mg/kg per day) for 21 d. Tumor growth was measured once each week, and tumor volume (V) was calculated with the following equation: V = (L × W2) × 0.52, where L is the length and W is the width of the xenograft. After 21 d, mice were killed under ether anesthesia, and tumors were excised and weighed. Apoptosis was evaluated through detection of DNA fragmentation with gel electrophoresis and the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay. Western blot analysis was performed to determine the expression of apoptosis-related proteins BAX, BCL2, APAF1, cleaved caspase-9, and cleaved caspase-3.
RESULTS: UDCA suppressed tumor growth relative to controls. The mean tumor volumes were the following: control, 1090 ± 89 mm3; 30 mg/kg per day, 612 ± 46 mm3; 50 mg/kg per day, 563 ± 38 mm3; and 70 mg/kg per day, 221 ± 26 mm3. Decreased tumor volumes reached statistical significance relative to control xenografts (30 mg/kg per day, P < 0.05; 50 mg/kg per day, P < 0.05; 70 mg/kg per day, P < 0.01). Increasing concentrations of UDCA led to increased DNA fragmentation observed on gel electrophoresis and in the TUNEL assay (control, 1.6% ± 0.3%; 30 mg/kg per day, 2.9% ± 0.5%; 50 mg/kg per day, 3.15% ± 0.7%, and 70 mg/kg per day, 4.86% ± 0.9%). Western blot analysis revealed increased expression of BAX, APAF1, cleaved-caspase-9 and cleaved-caspase-3 proteins, which induce apoptosis, but decreased expression of BCL2 protein, which is an inhibitor of apoptosis, following administration of UDCA.
CONCLUSION: UDCA suppresses growth of BEL7402 hepatocellular carcinoma cells in vivo, in part through apoptosis induction, and is thus a candidate for therapeutic treatment of HCC.

Abstract
An increase in interleukin (IL)-17A-producing cells, particularly at sites of tissue inflammation, is observed frequently, yet the mechanism is not fully understood. This study aims to dissect the role of IL-17 in autoimmunity-mediated neuroinflammation. The cytokine milieu containing elevated IL-17, which often appears in active states of autoimmunity, was mimicked in vitro by a supernatant obtained from rat peripheral blood monocytes stimulated with phorbol mystistate acetate (PMA)/ionomycin. The application of such inflammatory media on only primary cultured cerebellar granule neurones resulted in significant apoptosis, but the presence of astrocytes largely prevented the effect. The supernatants of the stimulated astrocytes, especially those that contained the highest level of IL-17, achieved the best protection, and this effect could be blocked by anti-IL-17 antibodies. Protein IL-17 inhibited intracellular calcium increase and protected the neurones under inflammatory attack from apoptosis. IL-17, but not interferon (IFN)-γ, in the inflammatory media contributed to astrocyte secretion of IL-17, which depended on the Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway activation. The astrocytes that were treated with IL-17 alone or with prolonged treatment of the inflammatory media failed to produce sufficient levels of IL-17. Moreover, confirmatory data were obtained in vivo in a monophasic experimental autoimmune uveitis (EAU) in Lewis rats; in this preparation, the high-level IL-17-containing the cytokine milieu was demonstrated, along with IL-17 secretion by the resident neural cells. The antagonism of IL-17 at a late stage disturbed the disease resolution and resulted in significant neural apoptosis. Our data show a dynamic role of IL-17 in the maintenance of homeostasis and neuroprotection in active neuroinflammation.

Abstract
Remodeling of extracellular matrix (ECM) and breakdown of blood-brain barrier (BBB) are crucial events in the pathogenesis of intracerebral hemorrhage (ICH). Matrix metalloproteinases (MMPs), particularly MMP-9 and MMP-2, are the most important degrading enzymes in the ECM and BBB. These proteolytic effects are controlled predominantly by tissue inhibitors of metalloproteinases (TIMPs). TIMP-1 is the main endogenous inhibitor of MMP-9. Two polymorphisms in the TIMP-1 gene (rs4898 and rs2070584) were selected through a literature review and successfully genotyped in a study sample of 410 ICH patients and 305 controls. Differences in genotype and allele frequencies of identified polymorphisms were determined. Furthermore, the serum levels of TIMP-1 were measured in a subgroup of 96 ICH patients on days 1 after ICH onset and 76 controls. Analyses showed that C allele of rs2070584 was significantly associated with the development of ICH in male subjects (p = 0.037, OR = 1.535, 95%CI 1.025-2.300). Multiple logistic regression analysis under three genetic models demonstrated both rs4898 and rs2070584 were not risk factors for ICH in female subjects. Furthermore, serum levels of TIMP-1 were significantly higher in ICH patients than those in normal controls. However, the serum levels of TIMP-1 showed a nonsignificant decrease, depending on the alleles and genotypes of rs2070584 both in male and female cases. In conclusion, this is the first association study of the TIMP-1 gene variants with ICH. Our data suggest that C allele of rs2070584 is a risk factor for ICH development in the Chinese male population. However, the precise function of this variant needs further investigation.

Abstract
The present paper tried to evaluate the effectiveness and improvement of variable selection before modeling with partial least squares regression (PLSR). Based on the independent test dataset, and compared with the PLSR model derived from all spectral variables, the prediction accuracy by modeling after variable selection has been improved. Thus, the results showed that variable selection was beneficial and necessary for soil carbon modeling by on-the-go NIRS. UVE (uninformative variable elimination) and UVE-SPA (successive projection algorithm) could perform effective variable selection and created promising models, and SPA and GA-PLS (genetic algorithm PLS) failed to make appropriate models. For synergy interval PLS (siPLS), change in interval number and number of interval for modeling could affect the prediction accuracy obviously. Promising models could be made by selecting appropriate interval number and number of interval for modeling, and siPLS could achieve similar prediction accuracy to UVE or UVE-SPA, and the shortcoming was that siPLS required a lot of computing time to find optimal combination of intervals for modeling.

Abstract
1. The relationship of polymorphisms in the Melanocortin 1 Receptor (MC1R) and Agouti Signalling Protein (ASIP) genes with plumage colour in Japanese quail was investigated by cloning and sequencing the entire coding regions from black, white and maroon Japanese quail embryos at 12 d of incubation. 2. Three SNPs were identified in the MC1R coding region by multiple alignment of sequences from individuals with different plumage colours. A missense C/T mutation located at 169 bp within the Open Reading Frame caused a Ile57Val mutation in the amino acid sequence, and had a significant relationship with the black colour. 3. The expression of MC1R was higher in black plumage quails than that in maroon plumage quails, whereas the expression of ASIP was higher in maroon plumage quails than that in black plumage quails. 4. It is concluded that the black plumage colour in Japanese quails may be caused by either increased production of MC1R or decreased production of ASIP.

Abstract
In our previous study, significantly high expression levels of matrix-remodeling associated 5 (MXRA5) were identified in fresh-cultured colorectal cancer (CRC) tissues compared with their normal adjacent mucosa by differential secretome analysis. Whether MXRA5 is a potential serum biomarker of CRC has not been evaluated. The aim of this study was to investigate the association between MXRA5 expression and clinicopathological characteristics of CRC patients. The MXRA5 expression levels were determined by quantitative real-time PCR (qRT-PCR) and immunohistochemistry (IHC) in 20 colorectal adenoma tissues, 156 CRC tissues and their corresponding adjacent normal mucosa. Relative quantity (RQ) value and immunoreactive score (IRS) were used for quantitative assessment. The staining for MXRA5 protein was mainly located in the cytoplasm of CRC cells. All CRC tissues were positively stained, with a higher expression rate (IRS>4) of 67% (105/156), and a lower expression rate (IRS≤4) of 33% (51/156). Meanwhile, their corresponding normal tissues exhibited little positive staining; the higher expression rate was 0% (0/156) and the lower expression rate was 25% (16/156). Additionally, more than half of the adenoma tissues were positively stained; the higher expression rate was 15% (3/20) and the lower expression rate was 50% (10/20). The MXRA5 protein positive staining rates were significantly correlated with the lesion sites (colon vs. rectum, 76 vs. 59%), TNM staging (I+II vs. III+IV, 56 vs. 73%) and metastasis (present vs. absent; 76 vs. 61%) with the most high positive staining rate observable in omental metastasis (82%). However, MXRA5 mRNA expression levels showed no significant differences between CRC tissues and their corresponding normal tissues, and no significant correlation between IRS and corresponding RQ value was observed. In this study, we present the first evaluation of MXRA5 protein expression in CRC tissue. Our results revealed that MXRA5 protein is aberrantly expressed in CRC tissues, and has potential value in early detection of CRC and prediction of omental metastasis.

Abstract
OBJECTIVE To apply the color Doppler in abdominal aortic balloon occlusion for pelvic or sacral surgery, and to evaluate its effectiveness in controlling blood loss. METHODS A Philips 4500 color Doppler was used to place abdominal aortic balloons in 20 patients with pelvic or sacral tumors who underwent surgery. The temporary abdominal aortic balloons were used for controlling blood loss in the surgery. Transesophageal echocardiography was performed to detect the renal blood flow. RESULTS Abdominal aortic balloons were successfully placed to the 20 patients, with a water injection rate of 10-18 (13.8 +/- 2.6) mL and a total of 45-180 min occlusion during the 70-450 (265 +/- 102) min surgery. The intraoperative blood loss ranged from 250 to 4000 (1357 +/- 997) mL. The water injection rate of abdominal aortic-balloons (Y) was correlated with the diameter of abdominal aorta (X): Y = 7.1602X + 2. 9968 (R2 = 0.7371, P < 0.05). Renal blood flow was not affected. The patients stayed in hospital for 7-13 (9.8 +/- 11.9) days after operation. One patient developed complications. The one year recurrence rate of tumors was 10%. CONCLUSION The color Doppler provides a simple and accurate instrument for abdominal aortic-balloon occlusion, with reliable blood loss control.

Abstract
The aim of this study was to elucidate the expression and localization of menin, a protein encoded by the multiple endocrine neoplasia type I (MEN1) gene, in 13 human cancer cell lines. Reverse transcription-polymerase chain reaction (RT-PCR) was used to determine the expression of the menin gene. The localization of the menin protein was detected by immunofluorescence microscopy. Western blotting was used to determine the quantity of menin in the nucleus, cytosol and membrane of the cells. RT-PCR revealed that menin was expressed in all the cell lines examined in this study. Immunofluorescence microscopy revealed that menin was located primarily in the nucleus. In the GES-1 (transformed human gastric epithelium), MCF-7 (breast cancer), SGH44 (brain glioma) and HeLa (cervical cancer) cell lines, menin was also found to be localized to the membrane, cytosol and nucleus. Moreover, in SGH44 cells more menin was located in the cytosol than the nucleus. Similar findings were obtained by western blotting. In the GES-1 and MKN-28 cells undergoing octreotide treatment, cytoplasmic menin was significantly increased compared with the control groups. Therefore, we suggest that menin is expressed in a number of human cancer cell lines and that the cytosolic distribution increases when the cells undergo octreotide treatment, indicating a new role for menin.

Abstract
Bone metastasis from cutaneous squamous cell carcinoma (SCC) is rare. We report a case of cutaneous SCC which was diagnosed by the presence of bone metastasis and treated with combination chemotherapy. A 53 year male had tissue contusion and persistent ulcer in the multiple regions of body for about 30 years and treat with Chinese Herbal Drugs in several hospitals, however, did not thorough cure. He was referred to our hospital for a dermatological examination in March 2009. Excisional biopsy and positron emission tomography-computed tomography (PET-CT) scan showed an invasive cutaneous SCC concomitant bone metastasis. Surgical treatment is limited, because of multiple cancerous ulcer and metastatic spreading. Therefore, we proceed to treat with oxaliplatin, tegafur and leucovorin (LV) combination chemotherapy and other adjuvant therapy. About 5 months following chemotherapy, the general situation of the patient was improved. Further cycle of chemotherapy resulted in complete disappearance of the tumor masses (confirmed by PET-CT). So far, there was no evidence of local recurrence or distant metastasis. This report indicates that the combination chemotherapy of oxaliplatin, tegafur and LV seems to have a considerable therapeutic effect for cutaneous SCC concomitant malignant bone metastasis.

Abstract
BACKGROUND AND PURPOSE the association of autosomal-dominant polycystic kidney disease (ADPKD) with intracranial aneurysm (ICAN) is well known but little is known about the characteristics of ICAN in ADPKD. The purpose of this study was to investigate the prevalence and characteristics of ICAN in ADPKD. METHODS we screened 355 patients with ADPKD (mean age, 46.5 ± 13.2 years; range, 7 to 87 years) with 3-dimensional time-of-flight MR angiography. Size, location, and morphology of aneurysms were assessed. The prevalence and characteristics of ICAN in patients with ADPKD were evaluated. Patients with ICAN found by MR angiography and moderate renal function subsequently were recommended to undergo digital subtraction angiography for comparison. RESULTS the prevalence of ICAN in ADPKD was 12.4% (95% CI, 8.95% to 15.82%) with an equal gender distribution. The prevalence increased as age increased, reaching a peak value of 23.3% (95% CI, 16.85 to 29.75%) in the 60- to 69-year age group. The prevalence of ICAN in patients with ADPKD with a positive family history of hemorrhagic stroke or ICAN was higher than patients with ADPKD lacking such family history (relative risk, 1.968; 95% CI, 1.57 to 2.67). The mean diameter of ICAN was 3.85 ± 3.25 mm. The most frequent site of ICAN was the internal carotid artery. The result of digital subtraction angiography of 15 patients with 18 ICANs and moderate renal function corresponded to the detection of MR angiography. CONCLUSIONS the characteristics of ICAN in patients with ADPKD were different from some previous reports. Systematic screening of ICAN with 3-dimensional time-of-flight MR angiography is recommended for patients with ADPKD, particularly for adult patients (≧30 years) or patients with a positive family history of hemorrhagic stroke or ICAN.
