Abstract
Objective: To explore the relationship between the time of sedentary behaviors and the risk of type 2 diabetes mellitus (T2DM) among rural adults in Henan Province. Methods: A total of 1 227 adults from Houzhai village in Zhengzhou City and Qiaomiao village in Jiaozuo City in Henan Province were randomly selected to participate in the survey; each of them finished a questionnaire and accepted physical examination and test of biochemical indicators. The participants were divided into case and control groups according to whether suffering from T2DM. A Pearson linear correlation and linear regression model analysis were used to investigate the relevance between the time of sedentary behaviors and fasting plasma glucose (FPG); meanwhile, a multi factor logistic regression model was used to analyze the relationship between the time of sedentary behaviors and T2DM. Results: The average FPG level among the participants was (5.4±2.5) mmol/L, and the average time of sedentary behaviors was (234.5±156.5) min per day. The prevalence rate of T2DM in subgroups whose time of sedentary behaviors were separately 0-<2.5, 2.5-<4.5, 4.5-<6.5 and ≥6.5 h/day were 15.8% (72/457), 19.3% (73/379), 16.7% (35/210) and 20.4% (37/181), respectively. There was a linear regression relationship between the time of sedentary behaviors(x) and FPG(y), the regression equation was: y=5.081+0.001x (t=3.01, P=0.003). Logistic regression model analysis showed that participants whose time of sedentary behaviors ≥6.5 h/day had significantly higher risk of T2DM than those whose time of sedentary behaviors between 0-2.4 h/day (OR=1.77, 95%CI: 1.11-2.81) after age and gender adjusted. However, the associations only exist in males and adults ≥50 years old according to sex and age stratification. It showed that participants with sedentary time ≥6.5 h/day had significantly higher risk of T2DM than those with sedentary time between 0-<2.5 h/d, with the corresponding OR (95%CI) at 2.34 (1.21-4.52) and 2.22 (1.19-4.16), respectively. Conclusion: The prolonged sedentary time is a risk factor of type 2 diabetes. After stratification by gender and age, the correlation only found in males and adults aged ≥50 years old.

Abstract
Objective: To compare the post-implant target volumes and dosimetric evaluation with pre-plan, the gross tumor volume(GTV) by CT image fusion-based and the manual delineation of target volume in CT guided radioactive seeds implantation. Methods: A total of 10 patients treated under CT-guidance (125)I seed implantation during March 2016 to April 2016 were analyzed in Peking University Third Hospital.All patients underwent pre-operative CT simulation, pre-operative planning, implantation seeds, CT scanning after seed implantation and dosimetric evaluation of GTV.In every patient, post-implant target volumes were delineated by both two methods, and were divided into two groups. Group 1: image fusion pre-implantation simulation and post-operative CT image, then the contours of GTV were automatically performed by brachytherapy treatment planning system; Group 2: the contouring of the GTV on post-operative CT image were performed manually by three senior radiation oncologists independently. The average of three data was sets. Statistical analyses were performed using SPSS software, version 3.2.0. The paired t-test was used to compare the target volumes and D(90) parameters in two modality. Results: In Group 1, average volume of GTV in post-operation group was 12-167(73±56) cm(3). D(90) was 101-153 (142±19)Gy. In Group 2, they were 14-186(80±58)cm(3) and 96-146(122±16) Gy respectively. In both target volumes and D(90), there was no statistical difference between pre-operation and post-operation in Group 1.The D(90) was slightly lower than that of pre-plan group, but there was no statistical difference (P=0.142); in Group 2, between pre-operation and post-operation group, there was a significant statistical difference in the GTV (P=0.002). The difference of D(90) was similarly (P<0.01). Conclusion: The method of delineation of post-implant GTV through fusion pre-implantation simulation and post-operative CT scan images, the contours of GTV are automatically performed by brachytherapy treatment planning system appears to have improved more accuracy, reproducibility and convenience than manual delineation of target volume by maximum reduce the interference from artificial factor and metal artifacts. Further work and more cases are required in the future.

Abstract
The sensitivity of tumor cells to treatment can be affected by autophagy. The drug resistance of esophageal cancer cells against cisplatin occurs during the long period of chemotherapy drug treatment. This study was designed to observe the effect autophagy has on the occurrence of esophageal cancer cell drug resistance against cisplatin and investigate its molecular mechanism in order to provide new details and strategies for the clinical treatment of esophageal cancer, especially cisplatin treatment. The detection methods used in this study were 3-(4,5-dimethylthiazd-2-yl)-2,5-dipheny-ltetrazolium bromide (MTT) colorimetric assay, clone survival technique, small interfering RNA (siRNA) transfection, and Western blot. Autophagy is a protection mechanism of drug-resistant cells processed by cisplatin, and maintains the cell clone survival ability. Autophagy activation requires the involvement of Atg5 and Atg7.

Abstract
Cytosine DNA methylation is a significant form of DNA modification closely associated with gene expression in eukaryotes, fungi, animals, and plants. Although the reference genomes of cotton (Gossypium hirsutum L.) have been publically available, the salinity-stress-induced DNA methylome alterations in cotton are not well understood. Here, we constructed a map of genome-wide DNA methylation characteristics of cotton leaves under salt stress using the methylated DNA immunoprecipitation sequencing method. The results showed that the methylation reads on chromosome 9 were most comparable with those on the other chromosomes, but the greatest changes occurred on chromosome 8 under salt stress. The DNA methylation pattern analysis indicated that a relatively higher methylation density was found in the upstream2k and downstream2k elements of the CDS region and CG-islands. Almost 94% of the reads belonged to LTR-gspsy and LTR-copia, and the number of methylation reads in LTR-gypsy was four times greater than that in LTR-copia in both control and stressed samples. The analysis of differentially methylated regions (DMRs) showed that the gene elements upstream2k, intron, and downstream2k were hypomethylated, but the CDS regions were hypermethylated. The GO (Gene Ontology) analysis suggested that the methylated genes were most enriched in cellular processes, metabolic processes, cell parts and catalytic activities, which might be closely correlated with response to NaCl stress. In this study, we completed a genomic DNA methylation profile and conducted a DMR analysis under salt stress, which provided valuable information for the better understanding of epigenetics in response to salt stress in cotton.

Abstract
Objective: To compare the dose distributions of postoperative plans with preoperative plans for seeds implantations of paravertebral/retroperitoneal tumors assisted by 3D printing guide template and CT guidance, explore the effects of the technology for seeds implantations in dosimetry level and provide data support for the optimization and standardization in seeds implantation. Methods: Between December 2015 and July 2016, a total of 10 patients with paravertebral/retroperitoneal tumors (12 lesions) received 3D printing template assist radioactive seeds implantations in department of radiation oncology of Peking University Third Hospital, and included in the study. The diseases included cervical cancer, kidney cancer, abdominal stromal tumor, leiomyosarcoma of kidney, esophageal cancer and carcinoma of ureter. The prescribed doses was 110-150 Gy. All patients received preoperative planning design, individual template design and production, and the dose distribution of postoperative plan was compared with preoperative plan. Dose parameters including D(90), MPD, V(100), V(150,)conformal index(CI), EI of target volume and D(2cc) of organs at risk (spinal cord, aorta, kidney). Statistical software was SPSS 19.0 and statistical method was non-parameters Wilcoxon symbols test. Results: A total of 10 3D printing templates were designed and produced which were including 12 treatment areas.The mean D(90) of postoperative target area (GTV) was 131.1 (97.8-167.4 Gy) Gy. The actual seeds number of post operation increased by 3 to 12 in 5 cases (42.0%). The needle was well distributed. For postoperative plans, the mean D(90,)MPD, V(100,)V(150) was 131.1 Gy, 69.3 Gy, 90.2% and 65.2%, respectively, and which was 140.2 Gy, 65.6 Gy, 91.7% and 26.8%, respectively, in preoperative plans. This meant that the actual dose of target volume was slightly lower than preplanned dose, and the high dose area of target volume was larger than preplanned range, but there was no statistical difference in P value between the two groups except V(150)(P=0.004). The actual dose conformity of target volume was worse than preplanned (CI was 0.58 and 0.62, respectively) and the difference was statistically significant(P=0.019). The actual dose of external target volume was higher than preplanned (EI was 55% and 45.9%, respectively) and the difference had no significance. For organs at risk, the actual mean D(2cc) of spinal cord, aorta and kidney was 24.7, 54.4 and 29.7 Gy, respectively, which was higher than preplanned(20.6, 51.6 and 28.6 Gy, respectively), and there was no significant difference in two groups. Conclusions: Most parameters of postoperative validations for 3D printing template assisted seeds implantation in paravertebral/retroperitoneal are closed to the expectations of preoperative plans which means the improvement of accuracy in treatment.

Abstract
Objective: To evaluate the clinical effectiveness of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for single-level lumbar spondylolisthesis treatment with bilateral Spotlight tubular channels. Methods: A total of 21 patients with lumbar spondylolisthesis whom underwent MIS-TLIF via bilateral Spotlight tubular channels were retrospectively analyzed from October 2014 to November 2015. The 21 patients included 11 males and 10 females ranged from 35 to 82 years (average aged 60.7 years). In term of spondylolisthesis category, there were 18 cases of degenerative spondylolisthesis and 3 cases of isthmic spondylolisthesis. With respect to spondylolisthesis degree, 17 cases were grade Ⅰ° and 4 cases were grade Ⅱ°. Besides, 17 cases at L(4-5) and 4 cases at L(5)-S(1)were categorized by spondylolisthesis levels. Operation duration, blood loss, postoperative drainage and intraoperative exposure time were recorded, functional improvement was defined as an improvement in the Oswestry Disability Index (ODI), Visual Analog Scale (VAS) was also employed at pre and post-operation (3 months and the last follow-up), to evaluate low back and leg pain. Furthermore, to evaluate the recovery of the intervertebral foramen and of lumbar sagittal curvature, average height of intervertebral space, Cobb angles of lumbar vertebrae and operative segments, spondylolisthesis index were measured. At the last follow-up, intervertebral fusion was assessed using Siepe evaluation criteria and the clinical outcome was assessed using the MacNab scale. Radiographic and functional outcomes were compared pre- and post-operation using the paired T test to determine the effectiveness of MIS-TLIF. Statistical significance was defined as P<0.05. Results: All patients underwent a successful MIS-TLIF surgery. The operation time (235.2±30.2) mins, intraoperative blood loss (238.1±130.3) ml, postoperative drainage (95.7±57.1) ml and intraoperative radiation exposure (47.1±8.8) were recorded. Different significance between 3 months post-operative follow-up and pre-operation was exhibited (P<0.01) in respects of lumbar VAS (t=11.1, P<0.01) and leg VAS (t=17.8, P<0.01). Moreover, final follow-up compared with pre-operation, and final follow-up compared with 3 months post-operative follow-up, VAS scores were also statistical difference (P<0.01). At the final follow-up, there were significant differences compared with pre-operation in ODI scores (t=30.1, P<0.01). Comparison between 3 months post-operative follow-up and pre-operation, statistical distinctions were demonstrated (P<0.05) in terms of mean height of intervertebral space (t=-10.9, P<0.01), the Cobb angles of lumbar vertebrae (t=-2.4, P<0.05), operative segments Cobb angles (t=-5.2, P<0.01) and Lumbar spondylolisthesis incidence (t=17.1, P<0.01). In addition, there was statistical difference between final follow-up and pre-operation (P<0.05) as well. For instance, mean height of intervertebral space (t=-10.5, P<0.01), the Cobb angles of lumbar vertebrae (t=-2.7, P<0.05), operative segments Cobb angles (t=-4.2, P<0.01) and Lumbar spondylolisthesis incidence (t=18.6, P<0.01) were involved. All spondylolisthesis vertebrae were restored completely. Lastly, at the last follow-up, 12 cases of grade 1 and 7 cases of grade 2 fusion were present as determined by the Siepe evaluation criteria. McNab scale assessment classified 17 patients having excellent clinical outcome, 3 patients in good and 1 patient having a better clinical outcome. Conclusion: MIS-TLIF with bilateral Spotlight tubular channels is a safe and effective approach for single segment lumbar spondylolisthesis.

Abstract
OBJECTIVES To explore the difference of eye movement characteristics between uncooperative and cooperative subjects with mental disorder after cerebral trauma. METHODS Thirty-nine subjects which needed psychiatric impairment assessment were selected. According to the binomial forced-choice digit memory test (BFDMT), all subjects were divided into cooperative and uncooperative groups. The subjects were asked to take the image completion test from Wechsler adult intelligence scale. Meanwhile, the data of eye movement track, fixation, saccade, pupil and blink were recorded by the track system of eye movement. RESULTS There were significantly differences (P<0.05) in the data of saccade between cooperative (10 cases) and uncooperative groups (29 cases). The frequency, time, amplitude, acceleration of saccadic in uncooperative group were significantly higher than cooperation group. The saccade latencies of cooperation group increased more than uncooperative group. There was a significant difference (P<0.05) in total discrete distance, average distance and total time of fixation between two groups, while the average duration time, number and frequency of fixation had no significantly difference (P>0.05) between two groups. And the blink frequency of cooperation group was higher than uncooperative group. CONCLUSIONS Eye movement can be an objective index for the primary judgment of cooperation level.

Abstract
Objective: To evaluate the clinical characteristics and risk factors for atrial fibrillation(AF)in patients with obstructive hypertrophic cardiomyopathy(OHCM). Methods: Patients with OHCM hospitalized in Fuwai Hospital from March 2011 to January 2016 were enrolled in the present study. Each patient underwent examinations including transthoracic echocardiography, body surface electrocardiograph or dynamic electrocardiogram (Holter). Cardiac troponin I (cTNI) and N-terminal pro-brain natriuretic peptide (NT-pro-BNP)levels were tested and clinical profiles were collected.The subjects were divided into two groups (the AF group and non-AF group). Risk factors for AF in patients with OHCM were assessed by multivariate logistic regression analysis. Results: A total of 309 patients were evaluated in the study. Among them, 17.5%( 54/309) patients were with AF.Age[(51.2±10.1)years vs (43.1 ± 14.4)years], New York Heart Association class(NYHA class)(2.8±0.5 vs 2.6±0.6), disease duration[6.0(4.0, 10.0)years vs 3.0(1.0, 6.0)years], left atrial (LA) dimension[(45.1±7.0)mm vs(42.6 ± 7.4)mm]and NT-pro-BNP levels[2 007(1 565, 3 199)pmol/L vs 1 509(729, 2 921)pmol/L]in the AF group were significantly higher than those in the non-AF group (all P<0.05). Multivariate logistic regression analysis indicated that advanced age(OR=1.04, 95% CI 1.01-1.08, P<0.01), higher NYHA class(OR=2.00, 95% CI 1.08-3.70, P<0.05)and longer disease duration(OR=1.08, 95% CI 1.01-1.15, P<0.05)were independent risk factors for AF in patients with OHCM, in which advanced age(OR=1.05, 95% CI 1.02-1.09, P<0.01), higher NYHA class(OR=3.39, 95% CI 1.53-7.54, P<0.01), LA dimension(OR=1.06, 95% CI 1.01-1.12, P<0.05)and longer clinical course(OR=1.12, 95% CI 1.04-1.20, P<0.01)were associated with AF in male patients, and advanced age (OR=1.05, 95% CI 1.01-1.09, P<0.05)and longer disease duration(OR=1.14, 95% CI 1.01-1.28, P<0.01)were associated with AF in female patients when stratified by gender. Conclusion: Advanced age , higher NYHA class and longer clinical duration are independent risk factors for AF in OHCM patients.

Abstract
OBJECTIVE To evaluate the survival outcomes of invasive fungal rhinosinusitis by analyzing the clinical features. METHODS A retrospective analysis was performed for cases of invasive fungal sinusitis proved by histological analysis between March 2006 and November 2015. All relevant factors including interval from the onset of symptoms to initiation of diagnosis, clinical characteristics, features of CT and MRI, treatment and prognosis were collected. A total of 18 patients (10 males; 8 females) were identified. The median age was 54 years old. Three patients suffered from acute invasive fungal sinusitis, while the other 15 suffered from chronic invasive fungal sinusitis. RESULTS The mean duration between onset of symptoms and diagnosis was 5 months. The most common symptom was headache (10/18), followed by visual disturbance (7/18), nasal obstruction (4/18), facial numbness and pain (2/18) and diplopia(2/18). Two patients had diabetes mellitus; one patient had ankylosing spondylitis receiving immunosuppressive drugs treatment for one year. Four patients had the disease confined in the sinus. Complications of this disease included orbital apex involvement in 6 patients, intraorbital and optic nerve involvement in 3 patients, cavernous sinus involvement in 5 patients, pterygopalatine fossa and infratemporal fossa involvement in 5 patients, intracranial extension involvement in 3 patients. Fungal species included aspergillus (15 cases) and mucor (3 cases). Seventeen patients received intravenous antifungal therapy after surgery. The duration of follow-up ranged from 1 to 60 months. Two patients reoccurred and one patient died of the disease. CONCLUSION Endoscopic debridement combined with intravenous antifungals is efficacious in the management of invasive fungal sinusitis.

Abstract
OBJECTIVE To investigate the association between body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), and the incidence risk of type 2 diabetes mellitus (T2DM). METHODS In total, 20 194 participants ≥18 years old were selected randomly by cluster sampling from two township (town) of the county in Henan province from July to August of 2007 and July to August of 2008 and the investigation included questionnaires, anthropometric measurements, fasting plasma glucose, and lipid profile examination were performed at baseline; 17 236 participants were enrolled in this cohort study. 14 720 (85.4%) were followed up from July to August 2013 and July to October 2014. Finally, 11 643 participants (4 301 males and 7 342 females) were included in this study. Incidence density and Cox proportional hazards regression models were used to evaluate the risk of T2DM associated with baseline BMI, WC, WHtR, and their dynamic changes. RESULTS After average of 6.01 years following up for 11 643 participants, 613 developed T2DM and the incidence density was 0.89 per 100 person-years. After adjusted for baseline sex, age, smoking, drinking, family history of diabetes, as well as the difference of fasting plasma-glucose (FPG), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), diastolic blood pressure (DBP) between baseline and follow-up, Cox Proportional-Hazards regression analysis indicated that T2DM risk of baseline BMI overweight group, BMI obesity group, abnormal WC group and abnormal WHtR group were significantly higher than that of the corresponding baseline normal groups , and the incidence risk of T2DM reached the highest for those whose baseline BMI, WC and WHtR were all abnormal, the corresponding HR (95%CI) were 2.05 (1.62-2.59), 3.01 (2.33-3.90), 2.34 (1.89-2.90), 2.88 (2.21-3.74), 3.32 (2.50-4.40), respectively. Whether baseline BMI/WC was normal or not, T2DM risk increased if baseline WHtR was abnormal, and the HR (95%CI) of baseline normal BMI/abnormal WHtR group, baseline abnormal BMI/abnormal WHtR group, baseline normal WC/abnormal WHtR group, baseline abnormal WC/abnormal WHtR group were 1.88 (1.29-2.74), 3.08 (2.34-4.05), 2.15(1.53-3.00), 3.22 (2.45-4.23), respectively. The analysis for dynamic changes of BMI, WC, and WHtR indicated that in baseline normal WC or WHtR group, T2DM risk increased when baseline normal WC or WHtR developed abnormal at follow-up, and the corresponding HR (95%CI) were 1.79 (1.26-2.55), 2.12(1.32-3.39), respectively. In baseline abnormal WC or WHtR group, T2DM risk decresed when baseline abnormal WC or WHtR reversed to normal at follow-up, and the corresponding HR (95%CI) were 2.16 (1.42-3.29), 2.62 (1.63-4.20), respectively. CONCLUSION BMI, WC, and WHtR were associated with increased T2DM risk. The more abnormal aggregation of BMI, WC, and WHtR presents, the higher T2DM risk was. T2DM risk could be decreased when abnormal WC or WHtR reversed to normal.

Abstract
Objective: To evaluate the application value of carbon lymph node tracing technique by preoperative endoscopic subserosal injection in laparoscopic radical gastrectomy. Methods: From June 2013 to February 2015, seventy eight patients with gastric cancer were enrolled and randomly divided into trial group and control group. Subserosal injection of carbon nanoparticles around the tumor was performed by preoperative endoscopic subserosal injection one day before the operation in trial group, while the patients routinely underwent laparoscopic gastrectomy in control group. Results of harvested lymph nodes, postoperative complications were compared between the two groups. Carbon nanoparticle-related side effect was also evaluated. Results: The average number of harvested lymph node in trial group was significantly higher than that in control group (35.5±8.5 vs 29.5±6.5, P<0.05). The rate of overall black-dyed harvested lymph node was 74.7% (1 035/1 386) in trial group, the black-dyed lymph node rate in D1 lymph node was 80.1%, which was significantly higher than that in D2 lymph node (69.8%, χ2=19.38, P<0.01). When comparing the lymph node with and without black-dyed in trial group, the rate of metastasis lymph node was significantly higher in lymph node with black-dyed (17.3% vs 4.0%, χ2=38.67, P<0.01). There was no significant difference in postoperative complications rate between two group (trial group 10.2%; control group 12.8%, χ2=0.00, P>0.05), and no carbon nanoparticle-related side effect was observed. Conclusion: Given a higher harvested lymph node number and a similar rate of complications, preoperative endoscopic subserosal injection of carbon nanoparticles was safe and feasible.

Abstract
Lumbar anesthesia is the preferred anesthetic approach for puerperae undergoing cesarean section in China. To observe the safety of administering different doses of ropivacaine for cesarean section and its pharmacodynamic mechanism, we randomly divided 180 pregnant women undergoing cesarean section into three groups: group A, 10 mg ropivacaine (0.50%); group B, 12 mg ropivacaine (0.50%); and group C, 14 mg ropivacaine (0.50%). Pharmacodynamic index, anesthesia quality and incidence of untoward reactions of each group were observed. Group A performed the poorest and group C the best in evaluation of sensory and motory block (P less than 0.05). With regard to evaluation of hemodynamic index, hemodynamic parameters of the three groups had significant differences after medication; mean arterial pressure (MAP) of patients in group B decreased at time points T1, T2 and T3 and heart rate (HR) became much higher at T1 (P less than 0.05); MAP of the patients in group C decreased at T1, T2, T3 and T4, but HR became higher at T1 and T2 (P less than 0.05); HR of group B was higher than that of group A at T1 (P less than 0.05); MAP of the patients in group C had a significant decrease at T1, T2, T3 and T4, but HR became higher at T2 (P less than 0.05); MAP of patients in group C significantly decreased compared to group B at T1 and T2, but HR became higher at T2 (P less than 0.05). Fluctuation of oxyhemoglobin saturation (SpO2) of all patients was between 95% and 99%. There was no occurrence of myocardial ischemia or arrhythmia. 1-min Apgar score of neonates of the three groups had no significant difference (P0.05). The incidence of adverse reactions of the patients in group C was much higher than that of the patients in the other groups (P less than 0.05). Twelve mg ropivacaine (5%) is the most suitable dose for pregnant women undergoing cesarean section as it can achieve a sound anesthetic effect and high safety and, moreover, has little influence on respiratory and circulatory functions.

Abstract
Objective: To analyze the difference of dosimetric parameters between pre-plan and post-plan of 125I radioactive seed implantation assisted by 3D printing individual non-coplanar template (3D printing template) for locally recurrent rectal cancer (LRRC). Methods: From February 2016 to April 2016, a total of 10 patients with locally recurrent rectal cancer received 125I seeds implantation under CT guidance assisted by 3D printing template in Department of Radiation Oncology, Peking University Third Hospital.Each patient underwent CT simulation, three-dimentional treatment planning pre-implantation, 3D printing template design, radioactive seed implantation assisted by 3D printing template and dosimetric verification post implantation. The median activity of seed was 0.63 mCi (0.58 to 0.7 mCi) (2.15- 2.59×107 Bq), and the median number of seeds was 80 (19 to 192). D90, D100, V100, V150, CI, EI, HI, D5cc, D2cc of bladder and bowel of pre-plan and post-plan were calculated, respectively.Paired t test was used to evaluate the difference of dosimetric parameters between pre-plan and post-plan. Results: The median D90 of pre-plan and post-plan were 13 761.0 and 12 798.8 cGy, respectively.The median D100 of pre-plan and post-plan were 5 293.6 and 5 397.9 cGy, respectively.The median V100 of pre-plan and post-plan were 90.0% and 90.0%, respectively.The median V150 of pre-plan and post-plan were 63.8% and 62.4%, respectively.The median CI of pre-plan and post-plan were 0.73 and 0.67.The median EI of pre-plan and post-plan were 0.22 and 0.30, respectively. The median HI of pre-plan and post-plan were 0.29 and 0.31.The median bladder D2cc of pre-plan and post-plan were 3 088.8 and 4 240.4 cGy, respectively.The median bowel D2cc of pre-plan and post-plan were 7 051.6 and 7 903.9 cGy, respectively. Conclusions: 3D printing template might be helpful for locally recurrent rectal cancer patients who received 125I radioactive seed implantation assisted by 3D printing individual template.Seed implantation might have more chances to achieve prescription dose and dose limitation of organs at risk of pre-plan, which is important for precise implantation and quality control.

Abstract
Objective: To study the correlation between MGMT expression, clinicopathologic features and post-chemotherapy prognosis in patients with primary central nervous system lymphoma diffuse large B-cell lymphoma (PCNS-DLBCL). Methods: MGMT expression was detected in 76 cases of PCNS-DLBCL by EnVision method with immunohistochemical staining.Follow-up data including treatment response and overall survival time, were analyzed. Results: The rate of MGMT expression in PCNS-DLBCL was 67.1%(51/76). The MGMT expression rate in male patients was higher than that in female(P<0.05). Univariate analysis showed that these clinical pathological characteristics affected the overall survival of PCNS-DLBCL patients, including age and Hans algorithm, although no statistical significance was detected(P value was 0.065 and 0.069 respectively). The overall survival of the patients with positive MGMT and aged over 60 years was shorter after chemotherapy than those without chemotherapy (P=0.022). In the patients aged over 60 years, the prognosis of MGMT-positive patients was significantly better than MGMT-negative patients (P=0.044). Conclusions: The expression of MGMT is more commonly found in male patients. In the patients aged over 60 years with the same therapy, the prognosis is better in the MGMT-negative ones. Detection of MGMT protein expression can provide some guidance in choice of treatment modalities in PCNS-DLBCL patients.

Abstract
Calcineurin B-like protein-interacting protein kinase (CIPK) plays a key regulatory role in the growth, development, and stress resistance of plants by combining with phosphatase B subunit-like protein. In the present study, CIPK genes were identified in the whole genomes of diploid cottons and their sequences were subjected to bioinformatic analyses. The results demonstrated that the CIPK gene family was unevenly distributed in two diploid cotton genomes. Forty-one CIPKs were identified in the D genome, mainly located on chromosomes 9 and 10, whereas thirty-nine CIPKs were identified in the A genome, mainly located on chromosomes 8 and 11. Based on the gene structures, CIPKs in cotton could be classified into two types: one that is intron-rich and the other that has few introns. Phylogenetic analysis revealed that the CIPK gene family members in cotton had close evolutionary relationships with those of the dicotyledonous plants, such as Arabidopsis thaliana and poplar. The analysis of transcriptome sequence data demonstrated that there were differences in gene expression in different tissues, indicating that the expression of the CIPKs in cotton had spatio-temporal specificity. The expression analysis of CIPKs under abiotic stresses (drought, salt, and low temperature) in different tissues at trefoil stage demonstrated that these stresses induced the expression of CIPKs.

Abstract
Fibronectin type III domain-containing 5 (FNDC5) protein induces browning of subcutaneous fat and mediates the beneficial effects of exercise on metabolism. However, whether FNDC5 is associated with hepatic steatosis, autophagy, fatty acid oxidation (FAO), and lipogenesis remains unknown. Herein, we show the roles and mechanisms of FNDC5 in hepatic steatosis, autophagy, and lipid metabolism. Fasted FNDC5-/- mice exhibited severe steatosis, reduced autophagy, and FAO, and enhanced lipogenesis in the liver compared with wild-type mice. Energy deprivation-induced autophagy, FAO, and AMPK activity were attenuated in FNDC5-/- hepatocytes, which were restored by activating AMPK with 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR). Inhibition of mammalian target of rapamycin (mTOR) complex 1 with rapamycin enhanced autophagy and FAO and attenuated lipogenesis and steatosis in FNDC5-/- livers. FNDC5 deficiency exacerbated hyperlipemia, hepatic FAO and autophagy impairment, hepatic lipogenesis, and lipid accumulation in obese mice. Exogenous FNDC5 stimulated autophagy and FAO gene expression in hepatocytes and repaired the attenuated autophagy and palmitate-induced steatosis in FNDC5-/- hepatocytes. FNDC5 overexpression prevented hyperlipemia, hepatic FAO and autophagy impairment, hepatic lipogenesis, and lipid accumulation in obese mice. These results indicate that FNDC5 deficiency impairs autophagy and FAO and enhances lipogenesis via the AMPK/mTOR pathway. FNDC5 deficiency aggravates whereas FNDC5 overexpression prevents the HFD-induced hyperlipemia, hepatic lipid accumulation, and impaired FAO and autophagy in the liver.

Abstract
The tolerance of plants to biotic and abiotic stresses could be improved by transforming with fungal resistance-related genes. In this study, the cDNA sequence (GenBank Acc. No. KP337939) of the resistance-related gene Hsp24 encoding the 24 kD heat shock protein was obtained from the biocontrol fungus Trichoderma asperellum ACCC30536. The promoter region of Hsp24 contained many cis-regulators related to stresses response, such as "GCN4" and "GCR1" etc. Hsp24 transcription in T. asperellum was up-regulated under six different environmental stresses, compared with the control. Furthermore, following heterologous transformation into Populus davidiana × P. alba var. Pyramidalis (Pdpap), Hsp24 was successfully transcribed in transformant Pdpap-Hsp24s. Pathogen-related genes (PRs) in four Pdpap-Hsp24s were up-regulated compared with those in the control Pdpap (Pdpap-Con). After co-culture of Pdpap-Hsp24s with the weak parasite Cytospora chrysosperma, the transcription of genes related to hormone signal pathway (JA and SA) were up-regulated in Pdpap-Hsp24s, and ethidium bromide (EtBr) and Nitro-blue tetrazolium (NBT) staining assays indicated that the cell membrane permeability and the active oxygen content of Pdpap-Hsp24s leaves were lower than that of the control Pdpap-Con. And when the Pdpap-Hsp24s were under the Alternaria alternate stress, the activities of superoxide dismutase (SOD) and peroxidase (POD) got higher in Pdpap-Hsp24s than that in Pdpap-Con, and the disease spots in Pdpap-Con leaves were obviously larger than those in Pdpap-Hsp24s leaves. In summary, Hsp24 of T. asperellum ACCC30536 is an important defense response gene, and its heterologous expression improved the resistance of transformant Pdpap-Hsp24s to C. chrysosperma and A. alternate.

Abstract
OBJECTIVE To apply the ' auto-regressive integrated moving average product seasonal model' in predicting the number of hand, foot and mouth disease in Shaanxi province. METHODS In Shaanxi province, the trend of hand, foot and mouth disease was analyzed and tested, under the use of R software, between January 2009 and June 2015. Multiple seasonal ARIMA model was then fitted under time series to predict the number of hand, foot and mouth disease in 2016 and 2017. RESULTS Seasonal effect was seen in hand, foot and mouth disease in Shaanxi province. A multiple seasonal ARIMA (2,1,0)×(1,1,0)12 was established, with the equation as (1 -B)(1 -B12)Ln (Xt) =((1-1.000B)/(1-0.532B-0.363B(2))*(1-0.644B12-0.454B12(2)))*Epsilont. The mean of absolute error and the relative error were 531.535 and 0.114, respectively when compared to the simulated number of patients from Jun to Dec in 2015. RESULTS under the prediction of multiple seasonal ARIMA model showed that the numbers of patients in both 2016 and 2017 were similar to that of 2015 in Shaanxi province. CONCLUSION Multiple seasonal ARIMA (2,1,0)×(1,1,0)12 model could be used to successfully predict the incidence of hand, foot and mouth disease in Shaanxi province.

Abstract
OBJECTIVE To clarify the advantages and the influence to reproductive outcome after laparoscopic salpingotomy with and without suturing for tubal pregnancy. METHODS We retrospectively analyzed the clinical data of patients underwent laparoscopic salpingotomy from March 2012 to October 2014 who were willing to reserve their reproductive function and were able to be followed up. Based on the operation procedure, the patients were assigned to undergo laparoscopic salpingotomy with suturing (group A; n=49) or without suturing (group B; n=69). An amount of 50 mg methopterin was injected at mesosalpinx during operation in all cases. Tubal patency of the trouble side was evaluated by liquid instillation. The operation time, amount of bleeding, the trouble side tubal patency rate 3 months after the surgery, pregnancy outcome 12 months after the surgery was compared between two groups. RESULTS Three months after the surgery the tubal patency rate of trouble side was 85.71% (42/49) in group A and 62.32% (43/69) in group B. There was significant differences (P<0.05) between two groups. Within twelve months of the surgery, the intrauterine gestation rate was 69.39% (34/49) in group A and 42.03% (29/69) in group B. Ectopic re-pregnancy rate of the trouble side was 10.20% (5/49) in group A and 27.54% (19/69) in group B. Secondary infertility rate was 14.29% (7/49) in group A and 27.54% (19/69) in group B. There was significant differences (P<0.05) between two groups. The trouble side tubal patency rate and intrauterine gestation rate of group A was significantly higher than that of group B, while the ectopic re-pregnancy rate of the trouble side and secondary infertility rate of group A was significantly lower than that of group B. CONCLUSIONS Suturing after laparoscopic salpingotomy can decrease the damage to fallopian tube and recover its normal anatomic structure. So the procedure involving suturing can effectively reserve reproductive function for the patients.
