Abstract
Spring viremia of carp virus (SVCV), as a high pathogenicity pathogen, has seriously restricts the healthy and sustainable development of cyprinid farming industry. In this study, we selected 5-Fluorouracil (5-Fu) as the drug model based on zeolitic imidazolate framework-8 (ZIF-8) to construct a drug delivery system (5-Fu@ZIF-8), and the anti-SVCV activity was detected in vitro and in vivo. The results showed 5-Fu@ZIF-8 was uniform cubic particle with truncated angle and smooth surface, and the particle size was 90 nm. The anti-SVCV activity in vitro results showed that the highest inhibition rate of 5-Fu was 77.93% at 40 mg/L and the inhibitory concentration at half-maximal activity (IC50) was 20.86 mg/L. For 5-Fu@ZIF-8, the highest inhibition rate was 91.36% at 16 mg/L, and the IC50 value was 5.85 mg/L. In addition, the cell viability was increased by 18.1% after 5-Fu treatment. Similarly, after 5-Fu@ZIF-8 treatment, the cell viability increased by 27.3%. Correspondingly, in vivo experimental results showed the viral loads reduced by 18.1% on the days 7 and the survival rate increased to 19.4% at 80 mg/L after 5-Fu treatment. For 5-Fu@ZIF-8, the viral loads reduced by 41.2% and the survival rate increased to 54.8%. Mechanistically, 5-Fu inhibits viral replication by regulating p53 expression and promoting early apoptosis in infected cells. All results indicated that 5-Fu@ZIF-8 improved the anti-SVCV activity; it may be a potential strategy to construct a drug-loaded system with ZIF-8 as a carrier for the prevention and treatment of aquatic diseases.

Abstract
OBJECTIVE To investigate the association between short-term exposure to indoor total volatile organic compounds (TVOC) and nocturnal heart rate variability (HRV) among young female adults. METHODS This panel study recruited 50 young females from one university in Beijing, China from December 2021 to April 2022. All the participants underwent two sequential visits. During each visit, real time indoor TVOC concentration was monitored using an indoor air quality detector. The real time levels of indoor temperature, relative humidity, noise, carbon dioxide and fine particulate matter were monitored using a temperature and humidity meter, a noise meter, a carbon dioxide meter and a particulate counter, respectively. HRV parameters were measured using a 12-lead Holter. Mixed-effects models were used to evaluate the association between the TVOC and HRV parameters and establish the exposure-response relationships, and two-pollutant models were applied to examine the robustness of the results. RESULTS The mean age of the 50 female subjects was (22.5±2.3) years, and the mean body mass index was (20.4±1.9) kg/m2. During this study, the median (interquartile range) of indoor TVOC concentrations was 0.069 (0.046) mg/m3, the median (interquartile range) of indoor temperature, relative humidity, carbon dioxide concentration, noise level and fine particulate matter concentration were 24.3 (2.7) ℃, 38.5% (15.0%), 0.1% (0.1%), 52.7 (5.8) dB(A) and 10.3 (21.5) μg/m3, respectively. Short-term exposure to indoor TVOC was associated with significant changes in time-domain and frequency-domain HRV parameters, and the exposure metric for most HRV parameters with the most significant changes was 1 h-moving average. Along with a 0.01 mg/m3 increment in 1 h-moving average concentration of indoor TVOC, this study observed decreases of 1.89% (95%CI: -2.28%, -1.50%) in standard deviation of all normal to normal intervals (SDNN), 1.92% (95%CI: -2.32%, -1.51%) in standard deviation of average normal to normal intervals (SDANN), 0.64% (95%CI: -1.13%, -0.14%) in percentage of adjacent NN intervals differing by more than 50 ms (pNN50), 3.52% (95%CI: -4.30%, -2.74%) in total power (TP), 5.01% (95%CI: -6.21%, -3.79%) in very low frequency (VLF) power, and 4.36% (95%CI: -5.16%, -3.55%) in low frequency (LF) power. The exposure-response curves showed that indoor TVOC was negatively correlated with SDNN, SDANN, TP, and VLF when the concentration exceeded 0.1 mg/m3. The two-pollutant models indicated that the results were generally robust after controlling indoor noise and fine particulate matter. CONCLUSION Short-term exposure to indoor TVOC was associated with significant negative changes in nocturnal HRV of young women. This study provides an important scientific basis for relevant prevention and control measures.

Abstract
Objective: To observe the effects of transcranial direct current stimulation (tDCS) on nerve injury markers and prognosis in patients with acute severe carbon monoxide poisoning (ASCOP) . Methods: In May 2021, 103 ASCOP patients were treated in the emergency department of Harrison International Peace Hospital of Hebei Medical University from November 2020 to January 2021. The patients were divided into two groups according to whether they received tDCS treatment. The control group (50 cases) were given oxygen therapy (hyperbaric oxygen and oxygen inhalation) , reducing cranial pressure, improving brain circulation and cell metabolism, removing oxygen free radicals and symptomatic support, and the observation group (53 cases) was treated with 2 weeks of tDCS intensive treatment on the basis of conventional treatment. All patients underwent at least 24 h bispectral index (BIS) monitoring, BIS value was recorded at the hour and the 24 h mean value was calculated. Neuron-specific enolase (NSE) and serum S100B calcium-binding protein (S100B) were detected after admission, 3 d, 7 d and discharge. Follow-up for 60 days, the incidence and time of onset of delayed encephalopathy (DEACMP) with acute carbon monoxide poisoning in the two groups were recorded. Results: The NSE and S100B proteins of ASCOP patients were significantly increased at admission, but there was no significant difference between the two groups (P=0.711, 0.326) . The NSE and S100B proteins were further increased at 3 and 7 days after admission. The increase in the observation group was slower than that in the control group, and the difference was statistically significant (P(3 d)=0.045, 0.032, P(7 d)=0.021, 0.000) ; After 14 days, it gradually decreased, but the observation group decreased rapidly compared with the control group, with a statistically significant difference (P=0.009, 0.025) . The 60 day follow-up results showed that the incidence of DEACMP in the observation group was 18.87% (10/53) , compared with 38.00% (19/50) in the control group (P=0.048) ; The time of DEACMP in the observation group[ (16.79±5.28) d] was later than that in the control group[ (22.30±5.42) d], and the difference was statistically significant (P=0.013) . Conclusion: The early administration of tDCS in ASCOP patients can prevent the production of NSE and S100B proteins, which are markers of nerve damage. and can improve the incidence and time of DEACMP.

Abstract
Tetracycline antibiotics (TCs) are a broad-spectrum antibiotic, widely used in livestock and poultry breeding. Residue of tetracycline antibiotics in animal manure may cause changes in vegetable TCs content and soil microbial community. On the basis of the investigation and analysis of TCs pollution in the soil of main vegetable bases and the livestock manure of major large-scale farms in Chongqing, China, field experiment was conducted to study the residues of tetracycline antibiotics in Brassica juncea var. gemmifera and soil under different kinds and different dosages of livestock manures. Effects of tetracycline antibiotics on the structure and diversity of soil microbial community were also investigated by high-throughput sequencing. TCs content in soil was increased by applying livestock manure. The contents of tetracycline, oxytetracycline (OTC) and chlortetracycline (CTC) in the soil under pig manure treatment were 171.07-660.20 μg kg-1, 25.38-345.78 μg kg-1 and 170.77-707.47 μg kg-1, respectively. The contents of TC, OTC and CTC in the soil under the treatment of chicken manure were 166.62-353.61 μg kg-1, 122.25-251.23 μg kg-1 and 15.12-80.91 μg kg-1, respectively. TCs in edible parts of Brassica juncea var. gemmifera was increased after livestock manure treatment Proteobacteria, Acidobacteria, Actinobacteria, Chioroflexi and Bacteroidetes under livestock manure treatment were the dominant phyla, accounting for 85.2-92.4% of the total abundance of soil bacteria. The soil OTUs under the treatment of pig manure was higher than that under the treatment of chicken manure. Biogas residue (Livestock manure after fermentation treatment) can effectively reduce the environmental and ecological risks caused by antibiotic residues.

Abstract
Objective: To Summarize the safety, clinical outcome and technical evolution of laparoscopic gastric cancer surgery. Methods: A retrospective cohort study was carried out. Clinical data of 3012 patients who underwent laparoscopic radical gastrectomy for gastric cancer from January 2010 to March 2022 at Department of General Surgery, the First Affiliated Hospital of Nanjing Medical University were retrospectively collected and analyzed. Case inclusion criteria were gastric malignancies confirmed by pathology, without distant metastasis by examination before operation and exploration during operation, patients undergoing laparoscopic radical gastrectomy, intact function of important organs and with complete data. Exclusion criteria were patients who underwent emergency gastric cancer resection due to gastric bleeding, perforation or obstruction, etc., tumor found to invade adjacent organs such as pancreas or transverse colon during the operation, conversion to open surgery during the operation, those who had other malignant tumors (except thyroid cancer) within 5 years, and those had severe cardiopulmonary, liver, or kidney insufficiency before surgery. Outcomes included: (1) baseline information of patients; (2) trend of the quantity of laparoscopic radical gastrectomy year by year; (3) evolution of the mode of digestive tract reconstruction; (4) periopertive outcome short-term complication was defined as complication occurring within 30 days after operation and classified accordiny to the clavien-Dindo criteria; and (5) 5-year overall survival. SPSS software was used for statistical analysis. Continuous variables that obeyed the normal distribution were expressed in the form of Mean±SD. Days of hospital stay that did not follow a normal distribution were expressed as median (Q1,Q3), and the Mann-Whiney U test was used for comparison. Discrete variables were expressed as cases (%), and chi-square test or rank sum test was used for comparison between groups. Linear regression analysis was used to analyze the relationship between the amount of surgery and the year of surgery. Kaplan-Meier method and log-rank test were used for survival analysis. Two-tailed P<0.05 was considered as statistically significant. Results: Among the 3012 cases, 2114 were male and 898 were female. The patients' average age at surgery was (61.1±10.7) years old. According to the number of cumulative cases, the patients were divided into three groups: early, intermediate and late, with 1004 patients in each group. The early group consisted of patients undergoing operation from January 2010 to October 2018, the intermediate group consisted of patients undergoing operation from October 2018 to January 2021, and the late group consisted of patients undergoing operation from January 2021 to March 2022. (1) General information: There were 691 (68.8%), 699 (69.6%) and 724 (72.1%) male patients in early, intermediate and late groups respectively; the average age increased from 56.6 years in 2010 to 62.8 years in March 2022. As for the tumor stage T1, T2, T3, T4, there were 49.0%, 14.4%, 23.9% and 12.6% in the early group; 47.5%, 12.9%, 26.9% and 12.6% in the intermediate group; 39.7%, 14.6%, 30.0%, and 15.6% in the late group, respectively. Patients with N0, N1, N2, N3a, N3b stage were 56.8%, 13.7%, 13.4%, 11.0%, and 5.0% in the early group; 55.7%, 12.9%, 12.8%, 11.6%, and 6.9% in the intermediate group; 51.0%, 16.1%, 12.8%, 12.5%, and 7.5% in the late group, respectively. (2) Year-by-year change in the number of gastric cancer operations: From 19 cases per year in 2010 to 786 per year in 2021, the annual number of gastric cancer operations was proportional to the year of operation (y=47.505x, R2=0.67). The proportion of patients with stage I disease showed a fluctuating downward trend over time, while the proportion of patients with stage III disease increased slightly, accounting for 34% until March 2022. (3) Evolution of digestive tract reconstruction methods: Except in 2010, the digestive tract reconstruction method of distal gastrectomy focused on Billroth-II+Braun anastomosis among patients undergoing laparoscopic gastric cancer surgery in other years, whose proportion had gradually increased from less than 20% in 2016 to about 70% after 2021; the gastrointestinal reconstruction methods after total gastrectomy had gradually increased in π anastomosis and overlap anastomosis since 2016, of which π anastomosis reached about 65% in 2019, and overlap anastomosis reached almost 30% in 2020; the anastomosis methods after proximal gastrectomy had been mainly double-channel anastomosis (54%) and esophagogastric anastomosis (30%) since 2016, and double-channel anastomosis accounted for up to 70% in 2019. (4) Operation time: The operation time of early, intermediate and late group was (193.3±49.8) min, (186.9±44.3) min and (206.7±51.4) min respectively. Intermediate group was significantly shorter than early group (t=3.005, P=0.003), while late group was significantly longer than early group (t=5.875, P<0.001) and intermediate group (t=9.180, P<0.001). (5) Postoperative hospital stay: The median length of hospital stay for gastric cancer patients in early, intermediate and late groups was 9 (8, 11) d, 8 (7, 10) d, and 8 (7.5, 10) d respectively. The postoperative hospital stay of intermediate group and late group was significantly shorter than that of early group (Z=-12.467, Z=-5.981, both P<0.001), but there was no significant difference between intermediate group and late group (Z=0.415,P=0.678). (6) Postoperative complication: The morbidity of short-term complication in early, intermediate and late group was 20.4% (205/1004), 16.2% (163/1004), and 16.2% (162/1004) respectively, and above morbidity of intermediate group and late group was significantly lower than that of early group (χ2=5.869, P=0.015; χ2=6.165, P=0.013), while there was no significant difference between intermediate group and late group (χ2=0.004,P=0.952). The morbidity of short-term complication of grade IIIor higher was 8.0% (80/1004), 7.6% (76/1004), and 4.9% (49/1004) in early, intermediate and late group respectively, and above morbidity of late group was significantly lower than that of early and intermediate group (χ2=7.965, P=0.005; χ2=6.219,P=0.013), while there was no significant difference between intermediate group and early group (χ2=0.111,P=0.739). (7) Survival analysis: The follow-up deadline for survival data was December 31, 2021, and the median follow-up time was 29.5 months. The overall 5-year survival rate of all the patients was 74.7%. The 5-year survival rates of stage I, II and III patients were 92.0%, 77.2%, and 40.3% respectively and 5-year survival rates of patients with stage IA, IB, IIA, IIB, IIIA, IIIB and IIIC were 93.2%, 87.8%, 81.1%, 72.7%, 46.2%, 37.1%, and 34.0% respectively. Conclusions: The number of laparoscopic gastric cancer operation in our center is increasing year by year. With the maturity of laparoscopic technology, the morbidity of complication in laparoscopic gastric cancer surgery is decreasing.

Abstract
Objective: To analyze the correlation of bispectral index (BIS) with the prognosis of patients with acute severe carbon monoxide poisoning (ASCMP) and its predictive value of adverse outcomes. Methods: In March 2021, 106 ASCMP patients who were treated in Harrison International Peace Hospital Affiliated to Hebei Medical University from January 2019 to December 2020 were taken as research objects. All patients underwent 24-hour BIS monitoring after admission, and were divided into good prognosis group (n=75) and poor prognosis group (n=31) according to the prognosis of the patients' cranial nerve function after 60 d. The general conditions, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHEⅡ) score, Glasgow Coma Scale (GCS) score at admission and 24-hour BIS mean were compared between the two groups. Pearson correlation analysis was used to analyze the correlations between the 24-hour BIS mean and GCS score at admission, APACHEⅡ score and coma time. The receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of 24-hour BIS mean, GCS score at admission, APACHEⅡ score and coma time on adverse outcome of ASCMP patients. Results: The coma time and APACHEⅡ score of the patients in the poor prognosis group were significantly higher than those in the good prognosis group, the GCS score at admission and 24-hour BIS mean were significantly lower than those in the good prognosis group (P<0.05) . Pearson correlation analysis showed that the 24-hour BIS mean was positively correlated with the GCS score at admission, and negatively correlated with the APACHEⅡ score, coma time (r=0.675, -0.700, -0.565, P<0.001) . The 24-hour BIS mean had the highest predictive value for adverse outcome of ASCMP patients, with a cut-off value of 74, the area under the curve was 0.883 (95%CI: 0.814-0.951, P<0.001) , and the sensitivity and specificity were 73.3% and 87.1%, respectively. Conclusion: The 24-hour BIS mean has a good correlation with the acute brain nerve injury, the severity of the disease and coma time of patients with ASCMP. And it has a high predictive value for the adverse outcome in patients with ASCMP.

Abstract
Objective: To explore the effect of fine particulate matter (PM2.5) pollution on depression hospitalization cost and length of stay in 57 cities of China. Methods: A total of 84 207 patients with depression in 57 cities of China from January 2013 to December 2017 were selected as the subjects. The demographic characteristics and hospitalization status of the patients were obtained from the database of basic medical insurance for urban workers and urban residents in China. The environmental exposure data of the same period were obtained from the national air quality real-time release platform of China Environmental Monitoring Station. A generalized additive model based on quasi-Poisson distribution was used to analyze PM2.5 exposure effect in each city, and the nonlinear mixing of moving average temperature, relative humidity and date was controlled by natural smooth spline function. Results: Among the included cities, southern cities accounted for 50.88% (29), and the number of female inpatients, hospitalization costs and hospitalization days accounted for 62.65%, 63.50% and 60.85% (42 735 cases, 567.78 million yuan and 1.14 million days, respectively). The proportion of hospitalized cases, hospitalization cost and length of stay in the age group of 40 to 64 years old were 59.15% (40 346 cases), 53.92% (482.15 million yuan) and 52.07% (0.98 million days), respectively. PM2.5 level was positively correlated with the number of hospitalized cases with depression, hospitalization cost and length of stay. When the 3-day moving average of PM2.5 exposure level increased by 10 μg/m3, the number of hospitalization cases increased by 0.64%. The attributed percentage (95%CI) of hospitalized cases, hospitalization costs and length of stay were 3.35% (0.57%-6.04%), 3.04% (0.52%-5.48%) and 3.07% (0.49%-5.56%), respectively. Subgroup analysis showed that the attributed percentage of hospitalization cases, hospitalization cost and length of stay to PM2.5 exposure ranged from 3.97% to 4.68%, 4.04% to 4.33% and 4.13% to 4.30% in northern China, male and cold season, respectively. Conclusion: PM2.5 exposure is associated with the increase of hospitalization cost and length of stay among Chinese urban population with depression.

Abstract
A total of 49 patients with cerebellopontine angle cholesteatoma from the Department of Neurosurgery, Affiliated Hospital of Xuzhou Medical University between January 2013 and January 2021 were recruited. All patients were evaluated by MRI scan before surgery and tumor resection was performed under microscope via retrosigmoid sinus approach. Then residual tumor was searched with 0°and 30°neuroendoscopy, and tumor resection was performed.Residual tumors were foundand resectedin 38 cases under theneuroendoscopy after routine microsurgery.Total and subtotalresections were performed in 44 cases and 5 cases, respectively. Complications included aseptic meningitis (n=8), cerebrospinal fluid leakage (n=1) and intracranial hematoma (n=2). Follow-up[42±3(6-72)months] was available in all patients. During follow-up, 45 cases (91.8%) had a Kar-nofsky Performance Status (KPS)score ≥80.Neuroendoscopy-assisted microsurgery for cerebellopontine angle cholesteatomas helps enhance the total resection rate and decrease the operative risk.

Abstract
Objective: To explore the effect of autologous skin paste on repairing wound of medium-thickness skin donor site. Methods: The prospective randomized controlled research method was applied. From October 2018 to December 2019, 18 patients with flame burn or hydrothermal scald, met the inclusion criteria were admitted to Jinhua Hospital Affiliated to Zhejiang University School of Medicine, including 15 males and 3 females, aged (45±6) years, and the wounds were repaired with medium-thickness skin grafts. The wound area after medium-thickness skin grafting was (121±33) cm2. The wound of donor site of medium-thickness skin graft in each patient was divided into 2 wounds in equal area and included into autologous skin paste group and conventional treatment group with random number table, with 18 wounds in each group.The wounds in autologous skin paste group were repaired with skin paste prepared with remaining skin fragments after autologous medium-thickness skin grafting, and the wounds in conventional treatment group were repaired with petroleum jelly gauze and sterile gauze. On 3, 7, 14, 21 d after operation, the wound healing in 2 groups was observed, and the wound healing rate was calculated. The wound healing time in 2 groups was recorded. Occurrences of subcutaneous effusion and infection on 3, 7, 14, 21 d after operation and wound rupture in 3 months after operation were observed. In 6 months after operation, the Vancouver scar scale (VSS) was used to evaluate the scar formation of wounds in 2 groups. Data were statistically analyzed with analysis of variance for repeated measurement, chi-square test, and group t test. Results: The wounds in 2 groups did not heal on 3 and 7 d after operation. The wound healing rate in autologous skin paste group was (29.8±2.5)% and (95.6±4.7)% on 14 and 21 d after operation, which were significantly higher than (25.8±2.9)% and (82.6±8.9)% in conventional treatment group (t=4.3, 5.6, P<0.01). The wound healing time in autologous skin paste group was (21.8±1.4) d, which was significantly shorter than (25.6±2.0) d in conventional treatment group (t=6.24, P<0.01). On 3, 7, 14, 21 d after operation, there were no complications such as subcutaneous effusion and infection in wounds of 2 groups. In 3 months after operation, ulceration occurred in wounds of 2 patients in autologous skin paste group, which was significantly less than 12 patients in conventional treatment group (χ2=11.688, P<0.01). The wounds with ulceration healed after dressing change. In 6 months after operation, the VSS score of wounds in autologous skin paste group was (9.1±1.1) points, which was significantly lower than (11.3±1.2) points in conventional treatment group (t=-5.75, P<0.01). Conclusion: The remaining fragments after autologous medium-thickness skin grafting are prepared into skin paste to repair wound of donor site of medium-thickness skin graft can shorten wound healing time, improve wound healing quality, reduce degree of scar hyperplasia, which has a good clinical effect.

Abstract
Objective: To investigate the therapeutic effects of first phase renal puncture and drainage guided by B ultrasound and second phase percutaneous nephrolithotomy(PCNL) in the treatment of urinary calculi complicated with pyonephrosis. Methods: From January 2014 to April 2018, 28 patients with upper ureteral segment and kidney calculi complicated with pyonephrosis were collected. All patients received the pyonephrosis puncture under B ultrasound. After the inflammation was controlled and the clinical situation improved, the second phase was treated by PCNL. During the operation, routine in dwelling ureteral stent drainage and renal fistula wereperformed. The outcomes of the operation were observed. Results: A total of 28 cases were successfully punctured, the obstruction was relieved and the inflammation was controlled. Additionally, the second phase of PCNL surgery was successful, and there were no significant stone residues after PCNL. There were no complications such as severe systemic inflammatory response syndrome and severe hemorrhage. After 3 to 12 months of follow-up, renal function was restored to varying degrees, and there were no renal failure patients who needednephrectomy. Conclusions: Early diagnosis of urinary calculi complicated with pyonephrosis is the key to successful treatment. Active and effective B ultrasound-guided renal puncture and drainage, drainage of pus, and removal of urinary obstruction can improve the safety of the second phase of PCNL, and thus it attaches great importance to the treatment of pyonephrosis.

Abstract
Objective: Exosomes are considered to mediate intercellular communication by delivering biomolecules like mRNA, miRNA into recipient cells. The purpose of this study was to evaluate the effects of exosomes secreted by fibroblasts from women with stress urinary incontinence (SUI-EXO) on endothelial cells angiogenesis. Methods: Primary fibroblasts were acquired from periurethral vaginal wall tissues and exosomes were prepared by ultracentrifugation of fibroblasts cells conditioned medium. The expression levels of pro-angiogenic and anti-angiogenic genes were assessed using qRT-PCR analysis. Migration of endothelial cells was measured by transwell assay, and the effects of SUI-EXO on angiogenesis were evaluated by performing a tube formation assay in vitro. Results: SUI-EXO was successfully isolated from fibroblasts cells conditional medium and transferred to endothelial cells efficiently. When the endothelial cells were treated with SUI-EXO, the expression levels of pro-angiogenic genes in fibroblasts were downregulated, and the expression levels of anti-angiogenic genes were upregulated significantly (P<0.01). Endothelial cells exhibited a decreased migratory capacity after treatment with SUI-EXO compared to exosomes from health women (64.6±8.7 vs 114.5±14.2,P<0.01), and tube formation of endothelial cells was also significantly inhibited in the SUI-EXO treated group as determined by the increase of the tube length (87.6±13.3 vs 168.5±28.3,P<0.01). Conclusion: This study suggests that SUI-EXO plays related roles in regulating endothelial cells angiogenesis and SUI-EXO maybe involve in the pathogenesis of SUI.

Abstract
Objective: To investigate the effect of biofeedback therapy on metabolic syndrome (MS) and the effect of different levels of job stress on the outcome. Methods: The physicians in tertiary hospitals who were diagnosed with MS from January to December, 2016 were divided into biofeedback group and health education group according to different intervention methods, and moderate group, medium group, and high group according to different levels of job stress. A 6-month intervention was implemented from May to October, 2017. A two-way factorial design was used to analyze the main effect of biofeedback on physical and biochemical parameters and the interaction of biofeedback and job stress. Results: After 6 months of intervention, the patients in both the biofeedback group and the moderate group had significantly decreased waist circumference, body mass index, systolic blood pressure (SBP) , diastolic blood pressure (DBP) , and levels of triglyceride (TG) , total cholesterol, low-density lipoprotein cholesterol (LDL-C) , and fasting plasma glucose (FPG) and a significantly increased level of high-density lipoprotein cholesterol (HDL-C) (all P<0.05) ; the patients in both the health education group and the moderate group had significantly decreased SBP, DBP, and levels of TG, LDL-C, and FPG (P<0.05) . The factorial analysis of variance showed that there was a synergistic interaction between the intervention method and job stress level in SBP, DBP, TG, HDL-C, LDL-C, and FPG among MS patients (P<0.05) . The high group had significantly more improvements in all indices compared with the medium group and the moderate group (P<0.05) . Conclusion: Biofeedback therapy can effectively improve blood pressure, blood lipids, and blood glucose in MS patients, and is more effective for patients with high job stress level.

Abstract
Objective: To investigate the clinical and pathological features, diagnosis and treatment of primary vulvar Paget disease (VPD) , and analyze the related factors that may affect the recurrence. Methods: A retrospective study was carried out on 36 patients diagnosed as VPD pathologically from January 1983 to December 2017 at Peking Union Medical College Hospital, Chinese Academy of Medical Sciences. The clinical and pathological features, diagnosis, treatment and prognosis and the factors influencing recurrence rate of VPD were analyzed. Results: (1) Totally 94% (34/36) of VPD occurred in postmenopausal women. Pruritus was counted 86% (31/36) of the main complaint. Lesions of vulvar were main symptom which had no specificity, acting as ulcer (67%, 24/36) , erythema (50%, 18/36) , depigmentation (42%, 15/36) , sclerosis (31%, 11/36) , and pigmentation (17%, 6/36) . The lesions invaded labium majus (97%, 35/36) , sometimes labium minus (53%, 19/36) , clitoris (28%, 10/36) , perianal (25%, 9/36) , orificium vaginae (3%, 1/36) , and meatus urinarius (3%, 1/36) . Approximately 19% (7/36) of VPD coexisted with intraepithelial neoplasia or adenocarcinoma of vulvar or other part of body. (2) Diagnosis and treatment: diagnosis was confirmed histologically by biopsy or pathologies after surgery, and immunohistochemical results were helpful for differential diagnosis. Surgery was the mean treatment method, 34 of all the 36 patients (94%, 34/36) underwent surgery for at least once, while 2 patients (6%, 2/36) were performed non-operative treatment. The surgical treatment included excision of focus, wide local excision, simple vulvectomy, and extensive vulvectomy. The non-operative treatment included radiotherapy, chemotherapy, laser, photodynamic therapy, and so on. (3) Prognosis: among 36 VPD patients, 4 were lost to follow-up with a 89% (32/36) follow-up rate. Median follow-up was 35.3 months (range,1 month to 31 years) . During the follow-up period, 2 patients were unable to judge whether they will relapse for the follow-up time did not reach half a year, 8 cases were unsuccessful operation, 20 cases succeeded, the achievement ratio was 71% (20/28) . Nine of twenty cases relapsed, the recurrence rate was 45% (9/20) . The median recurrence time was 14 months after operation. One patient of the 32 followed-up patients died, the mortality rate was 3% (1/32) . (4) The related factors affected the recurrence of VPD: t test was applied to the analysis of patients' age, rank test was used in the statistics of the time of confirmed diagnosis, the length and thickness of the resection focus. Fisher test was used to calculate whether the focus were limited to the epidermis, type of surgical procedures, distance between the margin and the focus, whether tumor cells infiltrated the margin. The results showed that none of the above terms in the first operation had significant contribution to recurrence (all P>0.05) . Conclusions: VPD may be a low potential malignancy, which could slowly progress into deep invasive disease. VPD is often associated with intraepithelial neoplasia or primary tumors of the vulva or somewhere else. Operations is the first choice for VPD, but consider for its high recurrence rate after operation, close follow-up should be strongly suggested.

Abstract
Objective: Pulmonary metastatic angiosarcoma is a rare, fatal disease that often presents as diffuse alveolar hemorrhage(DAH). In this report, clinical characteristics of pulmonary metastatic angiosarcoma were retrospectively reviewed. Methods: A total of 9 patients with angiosarcoma who presented as DAH were enrolled. Clinical data included age, gender, symptoms, smoking status, physical exam findings, pulmonary function tests, and radiology. Results: All patients were male with median age 41 years(range, 22 to 57 years). The most common symptom was hemoptysis(9/9). Other symptoms included dyspnea (5/9), cough(3/9), chest pain(3/9), fever(2/9,) and edema of the lower extremity and oliguria(4/9).The common misdiagnoses were tuberculosis(4/9), vasculitis(3/9) and other infection(1/9). Chest computed tomography showed bilateral,random distributed different-sized nodules(9/9),as well as ground-glass areas (9/9).The hearts, mainly right atrium, were the most common primary locations(7/9).Cardiac mass was the first manifestation in five patients by echocardiography(5/8).Two atrial masses were identified by computer tomography pulmonary angiography and magnetic resonance imaging respectively. Transbronchial lung biopsy failed to find malignancy. Computer tomography guided transthoracic needle biopsy was difficult to perform in most patients. Eight patients were diagnosed by surgical biopsy, either by lung biopsy(4/8) or cardiac biopsy(4/8).The median survival period was only 3 months after surgery. Conclusion: Metastatic pulmonary angiosarcoma should be considered in patients with DAH and multiple glass ground opacity and nodules on chest CT. Careful cardiologic monitoring is necessary. Surgical biopsy is reliable for diagnosis.

Abstract
OBJECTIVES To study the postoperative impact of cochlear implants (CIs) on tinnitus, as well as the impact of tinnitus on speech recognition with CI switched on. METHODS Fifty-two postlingual deafened CI recipients (21 males and 31 females) were assessed using an established Tinnitus Characteristics Questionnaire and Tinnitus Handicap Inventory (THI) before and after cochlear implantation. The tinnitus loudness was investigated when CI was switched on and off in CI recipients with persistent tinnitus. The relation between tinnitus loudness and recipients' satisfaction of cochlear implantation was analyzed by the visual analogue scale (VAS) score. RESULTS With CI 'OFF', 42 CI recipients experienced tinnitus postimplant ipsilaterally and 44 contralaterally. Tinnitus was totally suppressed ipsilateral to the CI with CI 'ON' in 42.9%, partially suppressed in 42.9%, unchanged in 11.9% and aggravated in 2.4%. Tinnitus was totally suppressed contralaterally with CI 'ON' in 31.8% of CI recipients, partially suppressed in 47.7%, unchanged in 20.5%. Pearson correlation analysis showed that tinnitus loudness and the results of cochlear implant patients satisfaction was negatively correlated (r = .674, p < .001). CONCLUSION The study suggests six-month CI activation can be effective for suppressing tinnitus. The tinnitus loudness may affect patients' satisfaction with the use of CI.

Abstract
Objective: To investigate the comprehensive nutritional status and diet behavior of middle aged and elderly women with osteoporosis, and thereby to explore the relationship between diet behavior and comprehensive nutritional status. Methods: 311 middle-aged and elderly women with osteoporosis in Chengdu were included in this study. Mini Nutritional Assessment (MNA) was applied to assess their comprehensive nutritional status. Information of social-demographic characteristics and diet behavior (about meals, snacks and water drinking, etc.) of the subjects was collected by questionnaire. Chi square test was used to assess the differences in nutritional status among patients who have different eating behaviors. Logistic regression analysis was performed to evaluate the relationship between diet behaviors and comprehensive nutritional status. Results: The mean MNA score of subjects was 25.8±2.5. 20.3% (63/311) of the subjets were at risk of potential malnutrition, but there was no malnourished subjects found. 46.9% (46/311) of the subjects were in good appetite. 95.2% (296/311) of them had a fixed food intake each meal. 65.8% (198/311) of them had snacks every day, and the most common choice was fruit (86.4% (248/287)). 54.8% (165/311) of them had initiative drinking water habits, and the most common choice was plain boiled water (79.9%, 246/308). 76.5% (238/311) of them had daily portable water less than 1 500 ml. After adjusting the effects of age, occupation and education level, bad appetite (OR=3.50, 95%CI: 1.18-10.62), unfixed food intake (OR=7.27, 95%CI: 1.40-35.83), and seldom or never intake of snack (OR=3.71, 95%CI: 1.42-9.72) were risk factors for malnutrition risk, while tea drinking was protective factor(OR=0.31, 95%CI: 0.11-0.93). Conclusion: Risk of potential malnutrition and unhealthy diet behavior among the middle aged and elderly women with osteoporosis should be paid more attention. Unhealtghy diet behavior has a negative effect on their comprehensive nutritional status.

Abstract
Objective: To investigate the dynamic change in cerebral oxygen utilization coefficient (O(2)UCc) in the early stage of acute severe carbon monoxide poisoning (ASCMP) and its value in predicting delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) . Methods: A prospective observational study was conducted for patients with ASCMP who were admitted to our hospital from November 2013 to March 2016, and their baseline features and physiological parameters were recorded. Observation ended at two months after acute poisoning; according to the presence or absence of DEACMP, the patients were divided into DEACMP group with 21 patients and non-DEACMP group with 64 patients. The change in O(2)UCc was monitored on admission and at 6, 24, 48, and 72 hours. Spearman correlation was used to investigate the correlation between O(2)UCc and Acute Physiology and Chronic Health Evaluation II (APACHE II) score, and the receiver operating characteristic (ROC) curve was used to evaluate the accuracy of O(2)UCc in predicting DEACMP. Results: Both groups had a significant increase in O(2)UCc on admission, and the DEACMP group had a significantly greater increase than the non-DEACMP group (52.57%±9.30% vs 41.46±%6.37%, P<0.05) . Then both groups tended to have a reduction in O(2)UCc, and the DEACMP group had a significantly higher O(2)UCc than the non-DEACMP group at 6, 24, and 48 hours (47.40%±7.92%, 39.38%±8.01%, and 32.29%±6.31% vs 34.51%±7.89%, 28.79%±5.4%, and 27.72%±5.46%, P<0.05) . On admission and at 6, 24, and 48 hours, O2UCc was positively correlated with APACHE II score (r=0.304, 0.398, 0.426, and 0.300, P=0.005, 0.000, 0.000, and 0.005) . The ROC curve showed that O(2)UCc had a value in predicting DEACMP on admission and at 6, 24, and 48 hours, and 6-hour O2UCc had the highest predictive value with an area under the ROC curve of 0.870 (95% confidence interval 0.794-0.947, P<0.05) . Conclusion: The dynamic change in O(2)UCc has a reference value in early identification of DEACMP, and O(2)UCc can be used as an important reference index for predicting DEACMP.

Abstract
Objective: Mesenteric panniculitis is an idiopathic, uncommon disease involving the adipose tissue of mesentery. The etiology, diagnosis and treatment are still unnoticed. We thus reported a case series to improve the understanding of this rare disorder. Methods: We retrospectively analyzed the clinical data of 12 patients with mesenteric panniculitis including manifestation, diagnosis, treatment and prognosis. Results: We found a male predominance (M∶F 3∶1) with the median age of 58 years old at diagnosis. The most common symptom was abdominal pain (9/12), followed by abdominal distension (3/12) and weight loss (3/12). Physical examination was unremarkable in the majority of patients (8/12). C reactive protein (9/12) and erythrocyte sedimentation rate (10/12) were normal in majority of patients. CT findings were of much diagnostic value. All patients had small intestinal mesentery involvement and multi-nodular appearance with increased fat density. Pseudo-capsule sign (8/12) and fat halo sign (6/12) were common. Pathological diagnosis was obtained in 4 cases showing fat tissue inflammation with local necrosis and fibrosis. Six cases all received prednisone, 2 with combined cyclophosphamide, 1 with azathioprine, 1 with tripterygium wilfordii. Short-term clinical response was achieved in all cases, but two patients relapsed. Conclusions: Mesenteric panniculitis occurs predominantly in middle-aged and elderly. Abdominal pain is the leading symptom. Inflammatory markers are often normal while computed tomography is the most important diagnostic tool. Surgery combined with cortical steroid and immunosuppressant agents is effective.

Abstract
Objective: To observe the effects of Ginaton on blood nitric oxide (NO) and nitric oxide synthase (NOS) in patients with delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Methods: A total of 116 patients with DEACMP who were treated in Emergency Department of Harrison International Peace Hospital Affiliated to Hebei Medical University from January 2012 to April 2016 were enrolled and ran-domly divided into control group and treatment group using a random number table, with 58 patients in each group. The patients in the control group were given conventional treatment including hyperbaric oxygen, preven-tion and treatment of cerebral edema, and promotion of brain cell metabolism, and those in the treatment group were given Ginaton in addition to the conventional treatment. The course of treatment was 2 weeks for both groups. The levels of neuron-specific enolase (NSE) , NO, NOS, and inducible nitric oxide synthase (iNOS) were measured before treatment and at 2 weeks after treatment, and the change in Mini-Mental State Examina-tion (MMSE) score and clinical outcome were observed in both groups. The correlation between the blood NO level on admission and the MMSE score was analyzed. Results: There was a significant difference in the overall response rate between the treatment group and the control group (81.03% vs 62.07%, χ(2) = 5.124, P=0.024). Be-fore treatment, there were no significant differences in the levels of NO and NSE, the activity of NOS and iN-OS, and MMSE score between the two groups (P>0.05). After treatment, both groups showed reductions in the levels of NO and NSE and the activity of NOS and iNOS, but the treatment group had significantly greater reduc-tions compared with the control group (P<0.05). Both groups showed a significant increase in the MMSE score after treatment, while the treatment group had a significantly greater increase compared with the control group (P<0.05). In the patients with DEACMP, the blood NO level on admission was negatively correlated with the MMSE score (r=-0.268, P=0.004). Conclusion: In the treatment of patients with DEACMP, Ginaton can effectively reduce the levels of NO and NSE and the activity of NOS and iNOS, increase the MMSE score, and promote the recovery of neurological function.

Abstract
Diabetic retinopathy is one of most common diabetic microvascular complications. In recent years the incidence of the disease has increased, hence early diagnosis and treatment are of great importance. In order to find reliable biological indexes to diagnose and treat type-two diabetes mellitus promptly, this study focused on the correlation between Cystatin C (Cys C) and retinopathy of type-two diabetes mellitus patients. One hundred and eighty type-two diabetes mellitus patients and one hundred healthy controls (the control group) were chosen in this study. Of the patients ninety-eight patients had typetwo diabetes mellitus without retinopathy (non-diabetic retinopathy group) and eighty-two had typetwo diabetes mellitus with retinopathy (diabetic retinopathy group). Correlation of Cys C and typetwo diabetic retinopathy was analyzed by examining the waist-hip ratio, fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), glycosylated hemoglobin (HbA1c), and Cys C of both groups. The results showed that FBG, TC, TG, LDL-C, HbA1c, Cys C in the type-two diabetes mellitus patients group were higher than those of the control group (P less than 0.05). Age, course of diabetes, FBG, HbA1c, and Cys C levels were statistically significant in both the DR group and NDR group (P less than 0.05). The result of logistic regression analysis indicates that there was a positive correlation between type-two diabetic retinopathy development and age, course of diabetes, and Cys C level (P less than 0.05). Thus, it can be seen that changes of Cys C levels can assist early diagnosis and treatment of diabetic retinopathy to some extent. The patients with high Cys C level, long course of diabetes, and old age are more likely to have diabetic retinopathy.

Abstract
Pathogenesis, clinical characteristics and treatments of vestibular migraine(VM) in recent years were retrospectively analyzed. The results showed that VM had diversified vestibular symptoms. VM may show a mild central and peripheral vestibular dysfunction during ictal and interictal period. Although no specificity, it could provide important references to identify VM. The pathogenesis of VM, which depended upon the clues of migraine, had been supposed to be probably related to genetic susceptibility, neurotransmitter changes induced by trigeminal nerve, and abnormal integration of central signal, and further exploration of functional abnormalities in brain-related areas showed by functional imaging technology may shed light on the pathogenesis of VM. Until now, the pharmacotherapies of VM have been still based on the treatment of migraine and the efficacy remains to be clarified.

Abstract
OBJECTIVE To investigate the value of serum presepsin concentration measurement in the clinical diagnosis and treatment of patients with pesticide poisoning patients. METHODS A total of 160 patients with pesticide poisoning were enrolled as study subjects and divided into moderate organophosphate pesticide poisoning group (40 patients) , severe organophosphate pesticide poisoning group (40 patients) , abamectin pesticide poisoning group (40 patients) , and paraquat poisoning group (40 patients). A total of 20 healthy volunteers were enrolled as the control group. All the patients with poisoning received conventional treatment of pesticide poisoning immediately after admission, and serum presepsin concentration was measured on days 1 (within 24 hours after poisoning) , 3, and 7 of admission, and biochemical and radiological parameters related to the patient's condition were also examined. The patients with a Presepsin concentration of >800 pg/ml on day 1 of admission were randomly divided into conventional treatment group and ulinastatin treatment group, and the treatment outcome was compared between the two groups. RESULTS Compared with the healthy control group, the groups with pesticide poisoning showed significant increases in serum Presepsin concentrations, with the highest degree of increase on day 1 (P <0.05). The serum Presepsin concentration was positively correlated with alanine aminotransferase, aspartate aminotransferase, creatine kinase, creatine kinase MB, lactate dehydrogenase, serum creatinine, blood urea nitrogen, interleukin-18, and white blood cell count, but negatively correlated with cholinesterase. In the conventional treatment group and ulinastatin treatment group, the overall response rate was 68% and 78.8%, respectively, with a significant difference between the two groups (P<0.05). In 40 patients with paraquat poisoning, 32 experienced an increase in serum presepsin concentration, and among these 32 patients, 27 (83%) experienced exudation on lung CT. CONCLUSION Serum Presepsin concentration measurement can assist early diagnosis, evaluation of disease severity, and guidance for clinical medication in patients with pesticide poisoning, especially in those with severe pesticide poisoning and a tendency to multiple organ failure.

Abstract
Cystoid macular edema (CME), a commonly seen sign for multiple fundus diseases, is able to induce visual deterioration. The incidence rate of CME is constantly increasing; however, the existing clinical treatments cannot achieve satisfactory curative effects. To explore the curative effect of intravitreous injection of triamcinolone acetonide (TA) in treating CME, this study carried out a clinical test on 39 patients (42 eyes) from The First Affiliated Hospital of Zhengzhou University who developed CME induced by central retinal vein occlusion (CRVO). All 42 eyes received intravitreous injection of 40 mg/ml TA (0.1 ml) and then were followed up for 11-23.5 months. Eyes were examined by slit-lamp microscope, fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) and best corrected visual acuity (BCVA), and intraocular pressure (IOP) of those eyes were detected before and after treatment. Average vision of eyes was 0.1 before treatment, and the vision improved in one month (vision ≥ 0.2: 100%; vision ≥ 0.5: 42.9%) and three months (vision ≥ 0.2: 64.3%; vision ≥ 0.5: 21.4%) after treatment; but as time went on, the vision of some patients declined; at the last follow-up, patients with vision ≥ 0.2 accounted for 28.6% and those with vision ≥0.5 accounted for 7.1%; compared to before treatment, 71.4% patients had improved vision and the remaining 28.6% had declined vision. Some patients were observed with high IOP during treatment, and 7 eyes were found with secondary cataract in posterior capsule of lens at the last follow-up. Intravitreous injection of triamcinolone acetonide proved to have significant short-term curative effect on CEM which is non-sensitive to conventional therapies, but it is likely to induce high IPO and posterior capsular opacification.

Abstract
This study evaluated the relationships among copeptin, ischemia-modified albumin (IMA), and extent of myocardial injury in patients with acute carbon monoxide poisoning (ACOP). A total of 110 patients with different degrees of ACOP were selected as the poisoning group, and 30 healthy individuals as the control group. The levels of troponin I (cTnI), IMA, and copeptin were detected. Based on the presence of complications, the patients were assigned to the complication (26 patients) or non-complication (84 patients) group. Levels of cTnI, IMA, and copeptin were compared among the control, complication, and non-complication groups. Compared with the control group, in the 2 h after admission, the IMA levels decreased and copeptin levels increased in the poisoning group; these changes were more significant in patients with severe ACOP than in those with mild ACOP, and the difference was statistically significant (P < 0.05). There were no differences in the IMA and copeptin levels between the groups 7 days after admission; the cTnI levels increased more significantly in patients with severe ACOP than in patients with mild and moderate ACOP, and the differences were statistically significant (P < 0.05). In the complication group, at 7 days after admission, the IMA levels decreased whereas the copeptin and cTnI levels were significantly higher than in the non-complication group, with a statistically significant difference (P < 0.05). IMA was negatively correlated with copeptin. IMA and copeptin detection is clinically useful in the early diagnosis and prognosis of ACOP-related myocardial injury and in guiding early clinical drug application.

Abstract
The molecular mechanism underlying muscle development in rabbits is not well-understood. In the current study, differentially-expressed genes were scanned using an expression profile chip in New Zealand white rabbits (introduced breed) and Fujian yellow rabbits (local breed), and some of the genes were tested using reverse transcription-polymerase chain reaction. The amplification results were consistent with the microarray data. Fourteen and 13 genes involved in muscle development were identified in the dorsal longissimus and leg muscles, respectively. Myh6, Myh7, Myh7b, Myo5b, Tnnc1, Tpm3, and Acta2 were scanned in the longissimus and leg muscles. Thus, these genes may be involved in muscle fiber formation and muscle development in rabbits. This study provides a theoretical basis for improving meat quality, as well as for the future development and utilization of local meat rabbit breeds.

Abstract
ABO-incompatible intestinal transplantation has rarely been performed due to poor patient outcomes. Herein we present a case of successful ABO-incompatible intestinal transplantation with a 2-year follow-up. A 16-year-old female with a history of extensive bowel resection received an ABO-incompatible living donor bowel graft from her father (blood type AB graft into a type A recipient). Posttransplant immunosuppression consisted of an initial anti-CD20, plasmapheresis/intravenous immunoglobulin before transplantation, followed by an anti-thymocyte globulin (ATG) induction and splenectomy, and maintenance with tacrolimus and prednisone. Her postoperative course was remarkable for a single episode of rejection on day 14 which responded promptly to treatment with methyprednisolone and ATG. Three months after transplantation, the patient developed an abdominal abscess requiring open surgical drainage. No viral infections were encountered. Posttransplant anti-B antibody titers and anti-B7 donor-specific antibody levels remained low. At a 2-year follow-up, the patient showed a progressive weight gain of 5.0 kg. This case illustrates that ABO-incompatible living-related bowel transplantation is immunologically feasible and is associated with good outcomes for the recipient. The management of blood type antibodies and the use of adequate immunosuppression in the early period of the procedure may be the keys to the success of future cases.

Abstract
Salusin-beta is newly identified bioactive peptide of 20 amino acids, which is widely distributed in hematopoietic system, endocrine system, and the central nervous system (CNS). Although salusin-beta extensively expressed in the CNS, the central cardiovascular functions of salusin-beta are unclear. Our main objective was to determine the cardiovascular effect of microinjection of salusin-beta into the nucleus tractus solitarii (NTS) in anesthetized rats. Bilateral or unilateral microinjection of salusin-beta (0.94-94 microg/rat) into the NTS dose-dependently decreased blood pressure and heart rate. Bilateral NTS microinjection of salusin-beta (9.4 microg/rat) did not alter baroreflex sensitivity. Prior application of the glutamate receptor antagonist kynurenic acid (0.19 microg/rat, n=9) into the NTS did not alter the salusin-beta (9.4 microg/rat) induced hypotension and bradycardia. However, pretreatment with the GABA receptor agonist muscimol (0.5 ng/rat) within the rostral ventrolateral medulla (RVLM) completely abolished the hypotension (-14+/-5 vs. -3+/-5 mm Hg, P<0.05) and bradycardia (-22+/-6 vs. -6+/-5 bpm, P<0.05) evoked by intra-NTS salusin-beta (9.4 microg/rat). In addition, we found that vagotomy didn't influence the actions of salusin-beta (9.4 microg/rat) in the NTS. In conclusion, our present study shows that microinjection of salusin-beta into the NTS significantly produces hypotension and bradycardia, presumably by suppressing the activities of presympathetic neurons in the RVLM.

Abstract
The amyloid C-terminal fragment (βCTF) of the amyloid precursor protein (APP) is the cleaved component of APP by beta secretase-1 (BACE1), which shows similar neurotoxicity as amyloid beta (Aβ) in many ways. Evidence suggested that in addition to Aβ, βCTF might also participate in the pathogenesis of Alzheimer's disease (AD). In recent years, the relationship between βCTF processing and hyperphosphorylated tau has attracted increasing research attention. In this study, we established an animal model of tau hyperphosphorylation with okadaic acid (OA) treatment, and analyzed βCTF processing in vivo. The βCTF level was found to increase in neurons, which was most likely caused by the induction of OA and BACE1 overexpression. Furthermore, these results provide the first evidence that βCTF can predominately accumulate in the axons of neurons in a hyperphosphorylated tau state in vivo, and suggested that the redistribution of βCTF is involved in the pathogenesis of AD. These results indicate that BACE1 could be a therapeutic target of AD by affecting the processing of βCTF.

Abstract
In this work, reduced graphene oxide (r-GO) and graphite nanosheet (GN) were obtained via the chemical approach. Furthermore, r-GO composites and GN composites were prepared with a paraffin wax host. r-GO composites show high dielectric properties and electromagnetic interference shielding efficiency (EMI SE). Compared with the GN composites, the loss tangent and EMI SE of the r-GO composites with the same mass ratio are enhanced ∼5 to 10 times and ∼3 to 10 times, respectively. The enhanced attenuation capacity arises from higher specific surface area, clustered defects and residual bonds of the r-GOs, which increase the polarization loss, scattering and conductivity of the composite. Moreover, the higher conductivity of r-GO composites leads to higher EMI SE compared with that of GN composites. These results suggest that r-GOs are highly promising fillers for microwave attenuation in the carbon family and that r-GO composites are high-performance EMI shielding materials with application anticipated to many fields.

Abstract
BACKGROUND Retrorectal tumors (RTs) are rare in adults. Their surgical excision is often difficult because of their anatomic location. The aim of this study was to evaluate the results of straight laparoscopic resection of RTs in our institution. METHODS Eight patients (six women and two men) with benign RTs were treated by laparoscopic resection in our tertiary care center between September 2012 and June 2013. Exclusion criteria included malignant tumors, lesions with fistula formation, and anterior sacral meningoceles. Clinical data, imaging features, operative details, pathological results, and treatment outcomes were reviewed and analyzed. RESULTS Eight cases of benign RT with an average diameter of 8.9 ± 1.7 cm were treated by a straight laparoscopic procedure. The mean operative time was 122 ± 36 min, and the average intraoperative blood loss was 46 ± 33 ml. The median postoperative stay was 5 days (range 3-8 days), and all patients were discharged without serious complications. During a median follow-up of 11 months, no tumor recurrence was observed. CONCLUSIONS In our experience, a laparoscopic approach is safe for removing benign tumors in the retrorectal space. This approach may provide access to this difficult-to-reach space and has the advantages of allowing excellent visualization, meticulous dissection, less morbidities, and fast recuperation.

Abstract
OBJECTIVES To examine the effects of cigarette smoking and smoking cessation on the incidence of ischaemic and haemorrhagic stroke in a multicentre prospective cohort study among Chinese. STUDY DESIGN A multicentre population-based prospective cohort study. METHODS The incidence of, and deaths from, stroke were monitored among 26,607 participants (12,560 men and 14,047 women) who were enrolled in 1986 and free from stroke until 2000. Cox's proportional hazard model was performed to obtain the hazard ratio (HR) of cigarette smoking for stroke risk after adjustment for major confounders. RESULTS After an average of 9.5 years of follow-up, 1108 subjects developed stroke. The excess risk of all types of stroke (total stroke) among male current smokers [HR 1.39, 95% confidence interval (CI) 1.15-1.67] was mainly due to a significantly elevated risk of ischaemic stroke (HR 1.49, 95% CI 1.17-1.90). A significantly increased risk for total stroke and ischaemic stroke was observed among men who smoked >15 cigarettes/day and men who had smoked for >25 years. The rate of smoking cessation was very low among Chinese men (7.2%) and women (1.5%). Smoking cessation did not appear to reduce the risk of haemorrhagic stroke, but may reduce the risk of ischaemic stroke; however, the possibility that this result was due to chance cannot be excluded (HR 0.74, 95% CI 0.26-2.08). CONCLUSION This study confirmed that cigarette smoking is a major determinant for the incidence of ischaemic and haemorrhagic stroke in Chinese men, and emphasizes the need for improved strategies to help people quit smoking.

Abstract
Dysfunction of the blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB) is a primary characteristic of multiple sclerosis (MS). We evaluated the protective effects of fasudil, a selective ROCK inhibitor, in a model of experimental autoimmune encephalomyelitis (EAE) that was induced by guinea-pig spinal cord. In addition, we studied the effects of fasudil on BBB and BSCB permeability. We found that fasudil partly alleviated EAE-dependent damage by decreasing BBB and BSCB permeability. These results provide rationale for the development of selective inhibitors of Rho kinase as a novel therapy for MS.

Abstract
We have studied the magnetic switching behavior of permalloy asymmetric rings using micromagnetic simulations. The simulation results have revealed that a domain wall trapping feature is present at the narrow arm of the asymmetric ring. This trapping feature is obtained via precise control of the lateral geometric features, the ring asymmetry and the film thickness. Our results show that the trapped domain walls do not annihilate until the magnetization in the wide arm is reversed under a relatively large magnetic field. Furthermore, the magnetic field strength needed to annihilate the domain wall is found to be decreasing with larger asymmetry ratio.

Abstract
Face-open nanoboxes of lead telluride and selenide have been synthesized by a simple hydrothermal method. Nano- and microcrystals of various morphologies, including microflowers, semi-microflowers, cubic nanoparticles, etc., have also been observed at different synthesis conditions. Temperature, time, and concentrations of various reactants play a major role in controlling the morphology and shape evolution of the product. This simple synthesis technique for the growth of various nano- and microstructures opens a new route to prepare hierarchical structures of a variety of binary semiconducting materials in a large quantity. A possible growth mechanism of such nano- and microstructures has been proposed.

Abstract
BACKGROUND Many people with epilepsy need not experience further seizures if the diagnosis and treatment are correct. Most epilepsy patients have convulsions, which are usually fairly easy to diagnose. This study tested a model for treatment of people with convulsive forms of epilepsy at primary health-care level in rural areas of China. METHODS Patients with convulsive epilepsy were identified at primary care level and provided with phenobarbital monotherapy. Local physicians, who were provided with special training, carried out screening, treatment, and follow-up. A local neurologist confirmed the diagnoses. Efficacy was assessed from the percentage reduction in seizure frequency from baseline and the retention of patients on treatment. FINDINGS The study enrolled 2455 patients. In 68% of patients who completed 12 months' treatment, seizure frequency was decreased by at least 50%, and a third of patients were seizure free. 72% of patients who completed 24 months' treatment had reduction of seizure frequency of at least 50% and a quarter of patients remained seizure free. Probability of retention was 0.84 at 1 year, and 0.76 at 2 years. Medication was well tolerated and reported adverse events were mild; only 32 patients (1%) discontinued medication because of side-effects. INTERPRETATION This pragmatic study confirmed that this simple protocol was suitable for the treatment of convulsive forms of epilepsy in rural areas of China. Physicians with basic training could treat epilepsy patients with phenobarbital, with beneficial effects for most patients with convulsive seizures. Few cognitive or behavioural adverse events were noted, but formal psychometric testing was not done.

Abstract
We have used the nervous system of the medicinal leech as a preparation to study the molecular basis of neural repair. The leech central nervous system, unlike mammalian CNS, can regenerate to restore function, and contains identified nerve cells of known function and connectivity. We have constructed subtractive cDNA probes from whole and regenerating ganglia of the ventral nerve cord and have used these to screen a serotonergic Retzius neuron library. This identifies genes that are regulated as a result of axotomy, and are expressed by the Retzius cell. This approach identifies many genes, both novel and known. Many of the known genes identified have homologues in vertebrates, including man. For example, genes encoding thioredoxin (TRX), Rough Endoplasmic Reticulum Protein 1 (RER-1) and ATP synthase are upregulated at 24 h postinjury in leech nerve cord. To investigate the functional role of regulated genes in neuron regrowth we are using microinjection of antisense oligonucleotides in combination with horseradish peroxidase to knock down expression of a chosen gene and to assess regeneration in single neurons in 3-D ganglion culture. As an example of this approach we describe experiments to microinject antisense oligonucleotide to a leech isoform of the structural protein, Protein 4.1. Our approach thus identifies genes regulated at different times after injury that may underpin the intrinsic ability of leech neurons to survive damage, to initiate regrowth programs and to remake functional connections. It enables us to determine the time course of gene expression in the regenerating nerve cord, and to study the effects of gene knockdown in identified neurons regenerating in defined conditions in culture.

Abstract
The authors carried out a door-to-door survey to determine the prevalence of epilepsy among 55,000 people in China. The lifetime prevalence was 7.0/1000, and 41% of all persons had never received appropriate treatment. The prevalence of active epilepsy was 4.6/1000, and 63% of people with active epilepsy had not received antiepileptic treatment in the week before the survey. Figures for the prevalence and the treatment gap were significantly higher than previous estimates.

Abstract
Ischemia and reperfusion in skeletal muscle is unavoidable during many reconstructive surgeries. Typical examples include replantation, transplantation, and free muscle transfer. One important complication during or after surgery is arterial insufficiency or a no-reflow phenomenon. The microcirculation is a primary target of ischemia and reperfusion injury. Vasoconstriction, poor blood flow, and capillary no-reflow, are the prominent features in the microcirculation seen during reperfusion. Currently, extensive efforts have focused on the theory that reactive oxygen species induce endothelial dysfunction in the microcirculation during reperfusion. Some intervention approaches, including ischemic preconditioning, are developing to interfere with or modulate the pathophysiological processes that are set in motion during ischemia and reperfusion.

Abstract
Spontaneous discharges of the rostral ventrolateral medulla (RVLM) neurons were extracellularly recorded by multi-barrelled microelectrodes in urethane-anesthetized rats. A total of 145 neurons were recorded: 33 were cardiovascular, 31 were nociceptive modulating, and 81 were unknown functional. The cardiovascular neurons were electrophysiologically identified through activating baroreceptor reflex by electrical stimulation of the aortic nerve and by intravenous injection of phenylephrine. Of the 33 cardiovascular neurons, 25 (76%) increased in firing rate after iontophoretical application of corticosterone sulfate (CORT), and 8 (24%) failed to respond. Of the 31 nociceptive modulating neurons excited by noxious stimulation, the firing rate decreased in 19 (64%), increased in 2 (6%), and did not respond in 10 (30%) after iontophoresis of CORT. Of the remaining 81 unknown functional neurons, 32 (40%) were excited, 5 (6%) inhibited, and 44 (54%) were not affected by CORT. These results demonstrate that CORT may modulate the activities of the neurons in RVLM through fast non-genomical effect, suggesting that the mechanism of the fast actions of CORT may play an important role in integration of the cardiovascular, nociceptive modulating activity under some conditions such as stress.

Abstract
As part of a longitudinal study performed in urban China, 37,655 subjects were evaluated for stroke risk factors, including having their blood pressure measured in a standard fashion. The cohort was followed for 3.5 years during which time 427 subjects experienced incident strokes--221 ischemic, 203 hemorrhagic, and 3 undefined. Both systolic and diastolic blood pressure were significantly related to risk of stroke and stroke type. Associations were stronger for systolic than diastolic blood pressure. These results emphasize the importance of systolic blood pressure, as opposed to diastolic, as a risk factor for stroke. In this study, the risk of stroke is increased by about 25% with each 10 mm Hg increase in systolic blood pressure.
