Abstract
Objective: To investigate the association between hyperuricemia and the risk for stroke occurrence, as well as the mediating effect of hypertension on this association. Methods: In this study, the China Chronic Diseases and Nutrition Surveillance system in 2015 was used as baseline data. We identified hospital admissions for stroke using the electronic homepage of inpatient medical records from 2013-2020, and death data were obtained from the 2015-2020 National Mortality Surveillance System. A retrospective cohort was established after matching and linking the database. The Cox proportional hazard regression model was used to analyze the relationship between hyperuricemia and the risk of stroke and its subtypes. Restricted cubic spline analysis was conducted to examine the dose-response relationship between serum uric acid levels and the risk for stroke. Mediation analysis was performed to investigate the mediating effect of hypertension on the association between hyperuricemia and the risk for stroke and its subtypes. Subgroup analyses were conducted based on gender and age groups. Results: A total of 124 352 study subjects were included, with an accumulative follow-up time of 612 911.36 person-years. During the follow-up period, 4 638 cases of stroke were found, including 3 919 cases of ischemic stroke and 689 cases of hemorrhagic stroke. The incidence density of stroke was 756.72 per 100 000 person-years, 641.37 per 100 000 person-years for ischemic stroke, and 114.60 per 100 000 person-years for hemorrhagic stroke. Multivariable Cox proportional hazards regression models showed that after adjusting for covariates, compared to those without hyperuricemia, individuals with hyperuricemia had a 16% higher risk for stroke [hazard ratio (HR)=1.16, 95%CI: 1.06-1.27], a 12% higher risk of ischemic stroke (HR=1.12, 95%CI: 1.01-1.24), and a 39% higher risk of hemorrhagic stroke (HR=1.39, 95%CI: 1.11-1.75). Mediation analysis showed that hypertension partially mediated the associations between hyperuricemia and the risk for stroke, ischemic stroke, and hemorrhagic stroke, with mediation proportions of 36.07%, 39.98%, and 25.34%, respectively. The mediating effect is pronounced in the male population and individuals below 65. Conclusion: Hyperuricemia is a risk factor for stroke, and hypertension partially mediates the effect of hyperuricemia on stroke.

Abstract
Objective: To explore the application of modified urethral separation method in artificial urethral sphincter (AUS) implantation in patients with stress urinary incontinence (SUI), and its influence on the results of urethral pressure profilometry. Methods: A prospective collection of clinical data was conducted on 25 patients with stress urinary incontinence who underwent modified urethral separation method in AUS implantation and underwent urethral pressure profilometry in Beijing Hospital, Beijing Jishuitan Hospital Affiliated to Capital Medical University and the Second Hospital Affiliated to Tianjin Medical University from March 2019 to June 2023. The improved urethral separation method was to borrow part of the white membrane tissue of the cavernous body while freeing the dorsal side of the cavernous body of the urethra. The circumference of the urethra, sleeve size, and urethral pressure were recorded, the patient's autonomous urinary control before and after surgery and the changes of the international consultation on incontinence questionnaire-short form (ICI-Q-SF) score, incontinence quality of life questionnaire (I-QoL) score, urinary frequency score, nocturia score were compared. Follow-up was conducted in the clinic or by telephone at 1, 3, 6, and 12 months after activation of the device, and once a year thereafter. Local skin status and urine control were assessed, residual urine volume was measured by ultrasound and subjective score scale was completed. Results: All patients were male, aged 27-85 (65.8±15.7) years old. The circumference of the cuff used in this study was 4.0 cm in 4 patients (16.0%), 4.5 cm in 16 patients (64.0%), 5.0 cm in 4 patients (16.0%), and 5.5 cm in 1 patient (4.0%). Among them, the urethral circumference matched the cuff size in 14 cases (56.0%), the urethral circumference was smaller than the cuff size in 4 cases (16.0%), and the urethral circumference was larger than the cuff size in 7 cases (28.0%). Preoperative urodynamic examination showed that the maximum urethral pressure (MUP) was (78.0±25.9) cmH2O, (1 cmH2O=0.098 kPa) and the maximum urethral closure pressure (MUCP) was (53.4±26.6) cmH2O. The MUP of AUS device in the inactivated state was (88.0±26.5) cmH2O, which was not significantly higher than that before operation (P>0.05). The MUCP was (68.2±24.5) cmH2O, which was significantly higher than that before operation (P<0.05). The MUP and MUCP of the AUS device in the activated state were (146.6±25.2) cmH2O and (123.0±28.3) cmH2O, which were significantly higher than those before surgery and in the inactivated state (both P<0.001). All patients in the group reached the social urinary control standards at the first month of device activation. During a follow-up period of 2-50 months, 22 patients (88.0%) used the initial AUS device and all met social urinary control standards. The AUS device was replaced in 1 case. One patient died of cerebrovascular accident. One patient removed the device due to complications. The number of pads [M (Q1, Q3)] used in 25 patients before and after operation was 4.5 (3.0, 6.5) and 1 (0, 1) respectively, with statistically significant differences (P<0.001). ICI-Q-SF score, I-QoL score, urinary frequency score and nocturia score of 25 patients were significantly improved after surgery (all P<0.05). The incidence of postoperative complications was 20.0% (5/25), including 2 cases of painless hematuria, 1 case of infection, 1 case of urethral erosion, and 1 case of dysuria. Except for one patient who experienced urethral erosion and had his sleeve removed, the remaining four patients regained social urination control with active support treatment, and no symptoms recurred until the last follow-up. Conclusion: The modified urethral separation method has no significant effect on urethral pressure in patients with SUI, and can increase the volume of peri-urethral tissue in the cuff, thereby reducing the risk of intraoperative urethral injury and the incidence of postoperative urethral erosion.

Abstract
Objective: To explore the utilization of cancer-related data from basic medical insurance databases in China, and promote the application of medical insurance data in cancer prevention and treatment. Methods: Database PubMed, Web of Science, Wanfang, and CNKI were used to select related research papers using data from basic medical insurance system in China published by December 2021. Descriptive analysis was conducted in terms of the number of publications, types of cancer, primary research contents and author affiliations. Results: A total of 65 papers were included in the study. The number of publications increased rapidly after 2016. The most studied cancer type was lung cancer, and healthcare costs were the most common research contents. Fujian, Beijing, and Anhui have made a better use of cancer-related medical insurance databases compared to other provincial regions. The accessibility of the New Rural Cooperative Medical Scheme data was limited due to the high regional barriers, while the accessibility of the urban basic medical insurance data was relatively high. The researchers from Peking University and Fudan University had higher utilization of basic medical insurance data compared with those from other institutions. Conclusions: The utilization of cancer-related data from basic medical insurance databases in China is limited because of poor accessibility, insufficient data sharing, and regional restrictions. Thus, it is urgent to improve data accessibility and promote the integration and utilization of regional medical insurance data.

Abstract
Aconitum kusnezoffii is a traditional Chinese medicine of Ranunculaceae family. Its toxicity is relatively strong, and its dosage is similar to that of poisoning. In clinical practice, poisoning events are often caused by excessive dosage or improper use. There is no specific antidote for kusnezoff root poisoning. Severe kusnezoff root poisoning can cause malignant arrhythmia and even death.A case of severe kusnezoff monkshood poisoning was reported in January 2021, which was treated with nificaran hydrochloride for injection in the emergency medicine department of the First Hospital of Handan City. The patient developed ventricular tachycardia, ventricular fibrillation and AS syndrome. In addition to conventional treatment, the patient did not have arrhythmia again after intravenous injection of 25 mg of nifekalan load and continuous pumping of 0.4 mg/kg/h for 7 hours, and did not relapse after discontinuation of nifekalan 24 hours later. It is suggested that the malignant arrhythmia caused by clinical severe kusnezoff monkshood poisoning can be controlled by nifekalan. Whether nifekalan is superior to conventional antiarrhythmic drugs still needs more accumulation and verification of clinical application data.

Abstract
Objective: Aim to observe the enrichment of Helicobacter pylori (Hp) in adenoma tissue of patients with colorectal adenoma and analyze its effect on the clinical and pathological characteristics of colorectal adenoma. Methods: The data of 1 622 cases of gastroenteroscopy in the Endoscopy Center of Wenzhou Integrated Traditional Chinese and Western Medicine Hospital Affiliated to Zhejiang University of Traditional Chinese Medicine from January 2019 to June 2021 were collected retrospectively. The general data, gastric HP infection, clinical and pathological features, HP methyl blue special staining, HP immunohistochemical staining and toll-like receptor5(TLR5) protein immunofluorescence of colorectal adenomas were compared between the colorectal adenoma group (743 cases) and the control group (879 cases). Results: There were 743 cases in the colorectal adenoma group, aged (54.5±12.3) years, and 56.0% were male. There were 879 cases in the control group, aged (55.6±12.1), and 58.4% were male. Gastric Hp was positive in 361 cases in the colorectal adenoma group with a positive rate of 48.6% and in 331 cases in the control group with a positive rate of 37.7%. The difference was statistically significant (P<0.001). Gastric HP infection significantly increased the risk of Hp enrichment in colorectal adenomas (OR=28.590;95%CI:18.554-44.055; P<0.001). At the same time, Hp enrichment in colorectal adenomas was the promoting factor of positive events in adenoma diameter, pathological adenoma type, and adenoma malignancy (RR=0.804,3.163,3.089,2.463, P<0.001). It was also found that the expression of TLR5 protein was increased in HP-enriched adenomas. Conclusion: There is a positive correlation between gastric HP infection and intestinal HP enrichment. The effect of intestinal HP enrichment on the clinical and pathological characteristics of colorectal adenoma is statistically significant, and its tumor-promoting effect may be related to the upregulation of mucosal TLR5 protein.

Abstract
Effective and comprehensive evaluation of cold stress is critical for healthy dairy cow breeding in the winter. Previous studies on dairy cow cold stress have considered thermal environmental factors but not physiological factors or air quality. Therefore, this study aimed to propose a multilevel fuzzy comprehensive evaluation (FCE) method for cold stress in dairy cows based on the analytic hierarchy process (AHP) and a genetic algorithm (GA). First, the AHP was used to construct an evaluation index system for cold stress in dairy cows from 3 dimensions: thermal environment (temperature, relative humidity, wind speed, and illumination), physiological factors (respiratory rate, body surface temperature), and air quality [NH3, CO2, inhalable particulate matter (PM10)]. Second, the consistency test of the judgment matrix was transformed into a nonlinear constrained optimization problem and solved using the GA. Next, based on fuzzy set theory, the comment set and membership function were established to classify the degree of cold stress into 5 levels: none, mild, moderate, high, and extreme. Then, the degree of cold stress in cows was obtained using multilevel fuzzy comprehensive judgment. To investigate the effect of illumination indicators on cold stress in dairy cows, 24 prelactation cows from the south and north sides were selected for a 117-d comprehensive cold stress evaluation. The results showed that the mean mild cold stress durations were 605.3 h (25.22 d) and 725.5 h (30.23 d) and the moderate cold stress durations were 67.2 h (2.8 d) and 96 h (4.0 d) on the south and north sides, respectively. Simultaneously, generalized linear mixed model showed that there were significant correlations between the daily cold stress duration and milk yield, feeding time, lying time, and active steps in the cows on both sides. This method can reasonably indicate cow cold stress conditions and better guide cold protection practices in actual production.

Abstract
Objective: To investigate the current status of the application of diagnostic and assessment tools for chronic obstructive pulmonary disease(COPD) by respiratory physicians in China. Method: An on-line questionnaire was designed to address the common questions in COPD diagnosis and evaluation, and this survey was conducted through Wechat. Result: A total of 3 204 valid questionnaires were collected. 71.7% of the physicians were from tertiary hospitals. 75.4% of the physicians diagnosed COPD strictly on the basis of lung function results after inhaled bronchodilators, and this percentage was higher in tertiary hospitals than in secondary hospitals(78.71% vs. 66.92%, P<0.01). 99.3% of the physicians evaluated symptoms of dyspnea, but 26.8% of physicians did not use a scoring system(CAT or mMRC) for quantitative assessment. Although 83.8% of physicians would use the guideline-recommended comprehensive assessment(ABCD classification), only 45.1% of them chose initial therapy exactly according to the classification. In addition, 28.3% of physicians did not routinely order blood eosinophil counts and 20.1% did not inquire the history of tuberculosis. Conclusions: Although most respiratory physicians followed the guidelines in the diagnosis and evaluation of COPD, the use of assessment tools was inadequate, which should be addressed in educational programs for COPD management.

Abstract
The objective of this study was to evaluate the effects of feeding gallic acid on the growth, nutrient digestibility, plasma metabolites, rumen fermentation, and bacterial community in the rumen fluid and feces of preweaning calves. Thirty-six female Holstein calves with similar ages (means ± SD; 3.1 ± 1.39 d) and body weights (40.8 ± 2.87 kg) were randomly assigned to receive 3 treatments. Calves were fed 1 of 3 treatments as follows: basal diet with no gallic acid (control), 0.5 g/kg gallic acid in starter diet (low), and 1 g/kg gallic acid in starter diet (high). The results showed that feeding gallic acid increased growth by improving the starter intake and average daily gain of the calves. The fecal score tended to decrease in a linear manner with the addition of gallic acid. Total-tract apparent protein digestibility tended to increase linearly with feeding gallic acid. Feeding gallic acid led to a linear increase in the plasma total protein and β-hydroxybutyrate levels. In addition, feeding gallic acid linearly increased catalase and total antioxidant capacity levels and decreased malondialdehyde and tumor necrosis factor-α concentrations. The concentrations of total volatile fatty acids, propionate, butyrate, and valerate in the rumen fluid increased linearly with the addition of gallic acid, resulting in a linear pH reduction. Feeding gallic acid linearly increased the relative abundances of Prevotella_1, Saccharofermentans, and Prevotellaceae_UCG-001 and linearly decreased the relative abundance of Prevotella_7 in the rumen fluid. The Shannon index of ruminal bacterial communities linearly increased by feeding gallic acid. Feeding gallic acid linearly increased the relative abundances of Ruminococcaceae_UCG-005, Bacteroides, and Christensenellaceae_R-7_group in the feces. In summary, feeding gallic acid improved growth, antioxidant function, and rumen fermentation and altered the bacterial community in the rumen fluid and feces of preweaning dairy calves.

Abstract
OBJECTIVE To understand the real prevalence of Clonorchis sinensis infections in the freshwater fish in mainland China, so as to provide insights into clonorchiasis control and detection of freshwater fish. METHODS All literatures reporting the prevalence of C. sinensis infections in the freshwater fish, the second intermediate host of the parasite, were jointly retrieved in Chinese and English electronic databases from January 1, 2010 to December 31, 2020, including Wanfang Data, CNKI, PubMed, Web of Science, Embase and Cochrane Library. All studies were screened based on inclusion and exclusion criteria, and the quality of all enrolled literatures was evaluated. The pooled prevalence of C. sinensis infections in freshwater fish and its 95% confidence interval (CI) were estimated using the software Stata version 15.0, and subgroup analyses were performed to investigate the region-, season- and sample source-specific pooled prevalence of C. sinensis infections in freshwater fish. In addition, the sensitivity and publication bias of all included studies were analyzed. RESULTS A total of 40 eligible literatures were included in this study, including 37 Chinese literatures and 3 English literatures, and there were 10 high-quality literatures, 27 moderate-quality literatures and 3 low-quality literatures. A total of 53 species containing 37 959 freshwater fish were reported in these 40 studies, and 73.58% (39/53) of freshwater fish species were identified with C. sinensis infections. Meta-analysis showed 23.5% [95% CI: (0.19, 0.28)] pooled prevalence of C. sinensis infections in freshwater fish in mainland China, and subgroup analyses higher prevalence of C. sinensis infections in freshwater fish in northeastern China [35.7%, 95% CI: (0.22, 0.50)] than in central [25.9%, 95% CI: (0.04, 0.48)] and southern China [20.6%, 95% CI: (0.09, 0.32)], higher prevalence of C. sinensis infections in freshwater fish sampled in spring [44.1%, 95% CI: (0.35, 0.53)] than in autumn [6.7%, 95% CI: (0.05, 0.08)] and summer [3.3%, 95% CI: (-0.01, 0.07)], and higher prevalence of C. sinensis infections in freshwater fish sampled from natural water [25.2%, 95% CI: (0.17, 0.33)] than from retail trades [22.2%, 95% CI: (0.17, 0.28)] and breeding chain [12.3%, 95% CI: (0.03, 0.22)]. However, all included studies had a publication bias with a low sensitivity. CONCLUSIONS The prevalence of C. sinensis infections is high in freshwater fish in mainland China, and there are still challenges for clonorchiasis control. Reinforcement of health education, diagnostics development and food safety supervision is recommended in future clonorchiasis control programs.

Abstract
OBJECTIVE To investigate the changes of mitochondrial metabolic functions of macrophages following Echinococcus multilocularis infections, so as to provide insights into the pathogenesis of alveolar echinococcosis. METHODS Two groups were assigned according to different treatment methods. In the culture group, mouse leukemic monocyte macrophage RAW264.7 cells were cultured with 2 000 E. multilocularis at a ratio of 500∶1, while RAW264.7 cells in the control group were given no treatment. Then, both the culture and control groups were further divided into the 24 h and 72 h subgroups. Mitochondria were stained with MitoTracker® Deep Red FM and the mean fluorescence intensity of macrophage mitochondria was measured with the Cytation 5 Cell Imaging Multi-Mode Reader. The mitochondrial DNA copy number was quantified using the quantitative real-time PCR (qPCR) assay, and the mitochondrial energy metabolism was monitored using the Seahorse XF assay. In addition, the mitochondrial reactive oxygen species and mitochondrial membrane potential were detected using flow cytometry. RESULTS The mean fluorescence intensities of macrophage mitochondria were significantly lower in the 24 h (15 341 ± 2 532 vs. 17 823 ± 3 429; t = 6.379, P < 0.01) and 72 h (18 102 ± 3 505 vs. 21 511 ± 5 144; t = 17.680, P < 0.01) culture subgroups than in the corresponding control subgroups, and lower mitochondrial DNA copy numbers were measured in the 72 h culture subgroup than in the 72 h control group [(3.23 × 109 ± 1.78 × 107) vs. (4.39 × 109 ± 3.70 × 107); t = 8.85, P < 0.001]. The oxygen consumption rates were significantly greater in the 24 h [(241.70 ± 73.13) pmol/min vs. (69.05 ± 52.30) pmol/min; t = 7.89, P < 0.01] and 48 h culture groups [(249.50 ± 42.06) pmol/min vs. (60.28 ± 40.66) pmol/min; t = 8.64, P < 0.01] than in the corresponding control groups, and a higher extracellular acidification rate was seen in the 48 h culture group than in the 48 h control group ([ 111.6 ± 17.49) mpH/min vs. (35.05 ± 7.57) mpH/min; t = 16.90, P < 0.01]. In addition, flow cytometry detected higher mean fluorescence intensity of mitochondrial reactive oxygen species (58 264 ± 10 087 vs. 4 307 ± 97; t = 12.930, P < 0.01) and lower mitochondrial membrane potential (9.833% ± 2.285% vs. 2.667% ± 0.208%; t = 6.645, P < 0.01) in the 72 h culture group than in the control group. CONCLUSIONS E. multilocularis infection may impair mitochondrial functions and inhibit oxidative phosphorylation of macrophages, resulting in increased macrophage glycolysis. It is speculated that the alteration of macrophage metabolic states may contribute to the mechanisms underlying the development and progression of alveolar echinococcosis.

Abstract
A study was conducted to investigate the inclusion effects of sugar beet pulp and rice straw mixture silage with inoculation (BRMS), in place of whole-plant corn silage (CS), on the dry matter intake, total-tract nutrient digestibility, plasma metabolites, rumen fermentation, and lactation performance in high-production dairy cows. Sixteen multiparous Holstein cows (body weight, 622 ± 35 kg; days in milk, 90 ± 11 d; mean ± standard deviation) were used in our experiments; the experiments were based on a repeated 4 × 4 Latin square design for 21 d, and each experimental period consisted of 14 d of adaptation, followed by 7 d of data collection. The 4 dietary treatments used were (dry matter basis): (1) 0% BRMS and 28.6% CS (0BRMS); (2) 4.3% BRMS and 24.3% CS (15BRMS); (3) 8.60% BRMS and 20.0% CS (30BRMS); and (4) 12.9% BRMS and 15.7% CS (45BRMS). The increasing inclusion of dietary BRMS was observed to linearly increase the total volatile fatty acids and the propionate concentration. The dry matter intake and digestibility values of neutral detergent fiber and acid detergent fiber increased linearly as the percentage of BRMS increased up to 45%. Milk yield linearly increased with the increase in the content of BRMS (39.0, 39.8, 40.9, and 40.3 kg/d for 0BRMS, 15BRMS, 30BRMS, and 45BRMS, respectively). The increasing inclusion of dietary BRMS induced a decrease in the ammonia nitrogen and milk urea nitrogen concentration, leading to a linear increase in milk protein production (1.15, 1.26, 1.35, and 1.27 kg/d for 0BRMS, 15BRMS, 30BRMS, and 45BRMS, respectively). In conclusion, the diets with the replacement of CS with BRMS up to 45% were beneficial to the production performance of high-production dairy cows, indicating that this method may be an appropriate use of sugar beet pulp and rice straw.

Abstract
The purpose of this research was to investigate the effects of replacing soybean meal (SBM) with a fermented corn gluten-wheat bran mixture (FCWM) on nutrient digestibility, lactation performance, plasma metabolites, ruminal fermentation, and bacterial communities in Holstein cows. Nine healthy multiparous (parity = 3) Holstein cows with similar body weights (624 ± 14.4 kg), days in milk (112 ± 4.2), and milk yields (31.8 ± 1.73 kg; all mean ± standard deviation) were used in a replicated 3 × 3 Latin square design with 3 periods of 28 d. Cows were fed 1 of 3 dietary treatments in which FCWM replaced SBM as follows: basal diet with no replacement (0FCWM); 50% replacement of SBM with FCWM (50%FCWM); and 100% replacement of SBM with FCWM (100%FCWM). The diets were formulated to be isocaloric and isonitrogenous. The results showed that the total-tract digestibility of dry matter and crude protein increased linearly with increased dietary FCWM, and we found a trend for increased total-tract neutral detergent fiber and potentially digestible NDF digestibility. Milk yield tended to increase in a linear manner as more FCWM was consumed, and energy-corrected milk production was significantly increased with FCWM supplementation as a result of increased milk protein and lactose yields. Plasma glucose and IgG concentrations increased linearly with increasing FCWM supplementation, but plasma malondialdehyde concentration decreased linearly. Concentrations of total volatile fatty acids and propionate showed a linear increase with increasing FCWM supplementation, leading to a linear decrease in pH. The relative abundance of ruminal Prevotellaceae, Veillonellaceae, and Prevotella 1 increased linearly with increasing FCWM supplementation, and the relative abundance of ruminal Succinivibrionaceae and Muribaculaceae decreased linearly. The relative abundance of fecal Ruminococcaceae, Prevotellaceae, and Ruminococcaceae UCG-005 increased linearly with increasing FCWM supplementation, but the relative abundance of fecal Peptostreptococcaceae decreased linearly. Overall, the replacement of SBM with FCWM altered the composition of the ruminal bacterial community and improved nutrient digestibility, lactation performance, and ruminal fermentation in cows, providing a data reference for the use of FCWM in dairy production.

Abstract
Pumpkin seed cake (PSC), a byproduct of pumpkin seed oil processing, is used in ruminant feed as a beneficial protein source. Experiments were conducted to evaluate PSC as a substitute for soybean meal in the diets of lactating cows based on performance, rumen fermentation, antioxidant function and nitrogen partitioning. Six multiparous lactating cows were used in a replicated 3 × 3 Latin square experiment with 27-day periods. The cows were randomly divided into three treatment groups: group (1) was fed a diet containing no PSC (0PSC), and groups (2) and (3) were fed diets in which soybean meal was replaced with PSC and dried distillers grains with solubles (DDGS) at levels of 50% (50PSC) and 100% (100PSC), respectively. The diets were isonitrogenous and contained identical roughage but different proportions of PSC and DDGS. Replacement of soybean meal with PSC and DDGS did not influence rumen degradation, milk performance, rumen fermentation, DM intake or apparent total tract digestibility, and nitrogen partitioning between milk, feces and urine did not differ in the animals fed the three diets. However, compared with a diet containing no PSC, the total antioxidant capacity (P < 0.05) and antioxidant enzymes (total superoxide dismutase, glutathione peroxidase and catalase) activities (P < 0.05) were increased in the animals that received the 50PSC and 100PSC diets. In contrast, addition of PSC significantly reduced concentrations of aspartate transaminase (P < 0.05), alkaline phosphatase (P < 0.05) and malondialdehyde (P < 0.05) in the plasma. These results demonstrate that PSC can be completely substituted for soybean meal in the diet of dairy cows without any negative impact on milk performance, rumen fermentation or apparent digestibility and that this dietary change improves antioxidant functions and blood parameters in dairy cows, indicating that PSC has the potential for use as a feed source for dairy cows.

Abstract
Wet corn gluten feed (WCGF) is a high moisture feed containing rapidly digestible, non-forage fiber and protein. The objective of this study was to investigate the effect of substituting WCGF and corn stover for alfalfa hay in total mixed ration (TMR) silage on lactation performance and nitrogen balance in dairy cows. Nine multiparous Holstein dairy cows (BW = 532 ± 28.9 kg and day in milk = 136 ± 5.6 d; mean ± SD) were used in a replicated 3 × 3 Latin square design with 21-d periods (14 d of diet adaption and 7 d of sample collection). Groups were balanced for parity, day in milk, and milk production and consumed one of three treatment diets during each period. The treatment diets were fed as TMR and contained similar concentrate mixtures and corn silage but different proportions of roughage and WCGF. The three treatments were: (1) 0% WCGF, 0% corn stover, and 22.1% alfalfa hay (0% WCGF); (2) 6.9% WCGF, 3.4% corn stover, and 11.8% alfalfa hay (7% WCGF); and (3) 13.3% WCGF, 4.9% corn stover, and 3.9% alfalfa hay (13.3% WCGF). Compared to the 0% WCGF diet, the cows fed the 7% and 13.3% WCGF diets had a higher milk yield and concentration of milk fat, protein, lactose, and total solids. Effective degradability of DM was higher in the cows fed the 7% and 13.3% WCGF diets than it was with the 0% WCGF diet. Cows fed the 13.3% WCGF had a higher CP effective degradability and a lower rumen undegraded protein than cows fed the 0% WCGF diet. The concentration of ruminal volatile fatty acids and ammonia-N was higher in cows fed the 7% and 13.3% WCGF diets than cows fed the 0% WCGF diet. The fecal N was lower in cows fed the 7% and 13.3% WCGF diets than it was in cows fed the 0% WCGF diet. Milk N secretion and milk N as a percent of N intake were higher in cows fed the 13.3% WCGF diet than cows fed the 0% and 7% WCGF diets. In conclusion, it appears that feeding a TMR silage containing WCGF and corn stover in combination, replacing a portion of alfalfa hay, may improve lactation performance and nitrogen utilization for lactating dairy cows.

Abstract
Objective: To clarify the clinical efficacy of Yiqi Huoxue recipe in the treatment of liver fibrosis of chronic viral hepatitis. Methods: An open, positive-drug, parallel-controlled study method was applied. A total of 207 cases of liver fibrosis with chronic hepatitis B and C diagnosed with liver biopsy and transient elastography were selected. According to the principle of syndrome differentiation in traditional Chinese medicine, self-made Yiqi Huoxue recipe (n = 127) and Fuzheng Huayu capsule (n = 80) were used for the treatment course of 24-48 weeks. Change score of TCM symptom, liver biochemistry, liver stiffness measurement (LSM), and noninvasive liver fibrosis index [aspartate transaminase to platelet ratio index (APRI), and fibrosis-4 score (FIB-4)] were compared between the two groups to evaluate the therapeutic effect of Yiqi Huoxue recipe on liver fibrosis. Results: Yiqi Huoxue recipe group and Fuzheng Huayu capsule group baseline LSM, APRI and FIB-4 was compared, and there was no statistically significant difference between them (P > 0.05). Yiqi Huoxue recipe and Fuzheng Huayu capsule received patients had improved symptom scores to a certain extent. Hepatic facies, discomfort over liver area, and soreness and weakness of waist and knees (P < 0.05) was significantly improved in Yiqi Huoxue recipe than Fuzheng Huayu capsule. Liver biochemical indicators (ALT, AST, GGT, ALP) had gradually relapsed with the extension of treatment duration and the normalization rate between the two groups after 24 to 48 weeks had reached 100% vs. 100%, 100% vs. 93.8%, 96.8% vs. 92.3% and 87.5% vs. 81.8%. After 12 weeks of treatment, APRI values of both groups had significantly reduced, and after 48 weeks of treatment, LSM values of both groups had significantly improved. Moreover, Yiqi Huoxue recipe FIB-4 score was significantly improved after 48 weeks of treatment, and the difference was statistically significant compared to Fuzheng Huayu capsule group (P < 0.05). After treatment, LSM, APRI, and FIB-4 total effectiveness in the two groups were 80.0% vs. 63.6%, P = 0.046; 68.4% vs. 52.0%, P = 0.052; 68.4% vs. 62.0%, P = 0.437, respectively. LSM total effectiveness was significantly higher in Yiqi Huoxue recipe treated group than Fuzheng Huayu capsule group. Conclusion: Traditional Chinese medicine Yiqi Huoxue decoction can be used as an optimal treatment for liver fibrosis of chronic viral hepatitis.

Abstract
1. Eggshell quality is important for the poultry industry. Calcium is deposited during eggshell formation, and protein kinase C alpha (PRKCA) is involved in transmembrane transport of calcium ions in cells. However, the biological function of PRKCA in poultry is still not understood. Therefore, the aim of this study was to explore the association of mRNA expression and single nucleotide polymorphisms (SNPs) of the PRKCA gene with eggshell quality in laying ducks. 2. The mRNA expression and SNPs of the PRKCA gene were detected by real-time fluorescence quantitative PCR (qRT-PCR) and sequencing of PCR products in 45-week-old female Sansui ducks, which is a high production layer duck breed in China. The association of mRNA expression and SNPs in the PRKCA gene with layer duck eggshell traits was analysed using SPSS (v18.0) software. 3. The results demonstrated that PRKCA mRNA was widely expressed in all examined tissues, and expression was highest in kidney and lowest in the gizzard. Furthermore, the PRKCA mRNA level in uterus was significantly positively correlated with eggshell strength and eggshell weight (P < 0.05). Three novel SNPs, the synonymous mutations of g.9571770 T > C in exon 5, g.9583222 C > T and g.9583227 G > A in exon 7, were found in the PRKCA gene, giving four haplotypes and 10 diplotypes, which affected the mRNA secondary structure and free energy. The g.9583222 C > T and g.9583227 G > A mutations were significantly associated with eggshell strength (P < 0.05). Diplotype H1H1 was advantageous for increasing the strength and thickness of an eggshell. 4. In conclusion, the study showed that the mRNA transcription and genetic variation in the PRKCA gene could significantly affect the strength of duck eggshell and that the PRKCA gene is an important candidate gene for improving eggshell quality in poultry.

Abstract
Objective: To evaluate whether midlife consumption of sugar-sweetened beverages (SSBs), including juices and soft drinks, were associated with late-life cognitive impairment in Chinese adults. Methods: Follow up was conducted for participants from Singapore Chinese Health Study, a population-based prospective cohort, for 16-23 (mean 20) years. The information about their SSBs consumption were collected at baseline survey from 1993 to 1998 by using a validated food frequency questionnaire and their cognition status were evaluated by using a Singapore-modified Mini-Mental State Examination Scale in the 3(rd) follow-up visit during 2014- 2016. Multivariable logistic regression models were used to estimate the ORs and 95%CIs. Results: A total of 16 948 participants were included in the analysis and 2 443 of them were identified as cognitive impairment using education-specific cutoffs. Sex, age, ancestral home, education level, physical activity level, total diet fiber intake level, BMI, alcohol drinking were significantly associated with cognitive impairment (P<0.05). After adjusted the above variables, potential dietary variables and disease status, no significant association was observed between SSBs consumption and cognitive impairment (P>0.05). Compared with those who never or hardly ever drank soft drinks, no significant differences in cognitive impairment risk were observed for those who drank soft drinks 2 or more times a week (OR=0.91, 95%CI: 0.77-1.08), those who drank 1 time a week (OR=1.00, 95%CI:0.82-1.23) and those who drank 1-3 times a month (OR=0.94, 95%CI: 0.80-1.09) (trend P=0.306). Compared with those who never or hardly ever drank juices, no significant differences in cognitive impairment risk were observed for those who drank juices 2 or more times a week (OR=1.03, 95%CI:0.88-1.20), those who drank 1 time a week (OR=0.96, 95%CI: 0.82-1.12) and those who drank 1-3 times a month (OR=0.94, 95%CI: 0.82-1.08) (trend P=0.930). No significant interactions were found with age, sex, and BMI status. Conclusion: SSBs consumption in midlife was not significantly associated with risk of late-life cognitive impairment in Singaporean Chinese adults with relatively low consumption levels. Further researches are needed to verify the results.

Abstract
OBJECTIVE To explore the expression of extracellular vesicle-derived lncZEB1-AS1 in esophageal cancer and its role in esophageal cancer progression. PATIENTS AND METHODS The extracellular vesicles (EVs) from esophageal cancer patients (n = 26) and normal subjects (n = 26) were isolated by differential centrifugation. The expression of lncZEB1-AS1 in EVs was detected by Real-time PCR (polymerase chain reaction). The clinical data of normal subjects and patients were analyzed. In addition, the concentration of EVs and lncZEB1-AS1 in blood samples from normal subjects and esophageal cancer patients were assessed. After co-culture of esophageal cancer cell line EC109 and EVs with or without lncZEB1-AS1 knockdown, cell proliferation was detected by CCK-8 assay. The possible target microRNAs of lncZEB1-AS1 in cytoplasm were predicted with miRcode, followed by correlation analysis of lncZEB1-AS1 and miR-214. Through literature review, lncZEB1-AS1 positively regulates ZEB1 expression, which was consistent with our result. RESULTS Quantitative Real-time PCR showed that the serum levels of EVs and the content of lncZEB1-AS1 in EVs from esophageal cancer patients were significantly higher than those in normal controls. LncZEB1-AS1 was overexpressed in esophageal cancer cells co-cultured with EVs of esophageal cancer patients. CCK-8 results indicated that EC109 cells co-cultured with EVs of esophageal cancer patients had stronger proliferative capacity. miRcode showed that miR-214 ranked the first of microRNAs that lncZEB1-AS1 might target, and miR-214 expression was significantly increased after lncZEB1-AS1 knockdown in EC109. After overexpressing lncZEB1-AS1 in EC109 or co-culturing EVs of esophageal cancer patients with EC109 cells, we found that lncZEB1-AS1 positively regulates ZEB1. In contrast, interfering with the expression of lncZEB1-AS1 in esophageal cancer cell lines can effectively reduce the expression of ZEB1. CONCLUSIONS EVs in the peripheral blood from esophageal cancer patients promote esophageal cancer progression by delivering lncZEB1-AS1 to esophageal cancer cells and targeting miR-214.

Abstract
OBJECTIVE Breast cancer cell infiltration, migration, and proliferation significantly affect its curative effect. Stemness gene octamer-binding transcription factor 4 (OCT4) upregulated in breast cancer tissue compared with normal control. MiRNA exhibits regulatory role in gene expression. This study adopted bioinformatics to predict the miRNA to regulate OCT4 gene and investigated its impact on breast cancer cell infiltration, migration, and proliferation. MATERIALS AND METHODS MirBase database was analyzed to explore the potential miRNA in regulating OCT4 based on human OCT4 gene sequence. MiRNA mimics and inhibitor were synthetized and transfected to BS524 cells. qRT-PCR was applied to test miRNA and OCT4 mRNA expressions in cells at 12 h, 24 h, and 48 h after transfection. Western blot was selected to detect OCT4 protein expression. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was selected to determine cell proliferation. Scratch assay was adopted to evaluate cell migration. Transwell assay was used to analyze cell infiltration. RESULTS MiR-145 may regulate OCT4 gene with score 82. OCT4 mRNA and protein increased at 12 h after transfection (p > 0.05). OCR4 gene significantly upregulated, cell proliferation, migration, and infiltration enhanced by miR-145 transfection compared with control (p < 0.05). OCT4 gene downregulated, while cell proliferation, infiltration, and migration markedly weakened in miR-145 inhibitor group compared with control (p < 0.05). CONCLUSIONS MiR-145 affects breast cancer BS524 cell proliferation, infiltration, and migration via positively regulating OCT4 gene expression.

Abstract
Objective: To assess the effectiveness and safety of sacral neuromodulation (SNM) therapy for men with idiopathic dysuria. Methods: From January 2012 to December 2016, a total of 26 patients treated with SNM therapy from multi-center across the country were retrospectively studied. The age ranged from 19 to 86 years with an average age of 45.2 years. Patients suffered from one or multiple urinary symptoms such as frequency of urination, urgency, urinary retention, etc. All patients had received more than two types of conservative therapy including oral and behavioral therapy, but had poor or no improvement. The voiding diary, urgency score and the quality of life score before implantation, in stageⅠ after implantation and stage Ⅱ after permanent implantation were recorded and compared. Results: A total of 22 patients chose to receive IPG at the end of stageⅠ therapy while 4 patients refused further stage Ⅱ therapy because of dissatisfactory effect. The conversion rate of stage Ⅰ to stage Ⅱ was 84.6% (22/26). The average follow-up time was 19.2 months, ranging from 3 to 63 months. The baseline of residual urine, voiding frequency and average voiding amount and those after stage Ⅰ therapy were [5 (0, 137.5) ] ml vs [0 (0, 40) ] ml, 14.6±6.1 vs 9.1±2.8, [100 (80, 135) ] ml vs [190 (150, 210) ] ml, respectively. The differences were statistically significant(all P<0.05).However, no significant differences were found in urination volume and quality of life (QoL) before and after implantation(P>0.05). During an average follow-up time of 19.2 months after the permanent implantation, over 80% patients had an improvement of residual urine volume by more than 50% after permanent implantation while the improvement was 55.6% after stage Ⅰ therapy, suggesting that the improvement of residual urine volume might be positively correlated with the duration of regulation. No significant differences were found in other parameters between stage Ⅰ and Ⅱ therapy. No adverse events like wound infection and electrode dislocation happened during our study. Conclusions: SNM is an effective and safety procedure for male patients with idiopathic dysuria, with a relatively high transfer rate. The medium-term curative effect is stable. The duration of regulation may be positively correlated with the improvement of residual urine.

Abstract
Vaccination is a widely used therapeutical strategy in aquaculture, but whether vaccination elicits stress responses in the central neuroendocrine system and enhances the crosstalk between the immune and endocrine systems in the brain or pituitary after vaccination is unclear. To answer this question two experiments using two different vaccine exposure routes, i.e., bath or intraperitoneal (i.p.) injection, were carried out on gilthead seabream (Sparus aurata L.). In the first one, the stress responses of fish subjected to waterborne Vibrio anguillarum bacterin were compared with responses after air exposure or their combination. In the second experiment, fish were subjected to an intraperitoneal injection of Lactococcus garvieae bacterin and we assessed the central stress response and also whether or not a significant immune response was induced in brain and pituitary. In both experiments, blood, brain and pituitary tissues were collected at 1, 6, and 24 h post stress for plasma hormone determination and gene expression analysis, respectively. Results indicated that bath vaccination induced a decreased central stress response compared to air exposure which stimulated both brain and pituitary stress genes. In the second experiment, injection vaccination kept unchanged plasma stress hormones except cortisol that raised at 6 and 24 h. In agreement, non-significant or slight changes on the transcription of stress-related genes were recorded, including the hormone genes of the hypothalamic pituitary interrenal (HPI) axis and other stress markers such as hsp70, hsp90, and mt genes in either brain or pituitary. Significant changes were observed, however, in crhbp and gr. In this second experiment the immune genes il1β, cox2, and lys, showed a strong expression in both brain and pituitary after vaccination, notably il1β which showed more than 10 fold raise. Overall, vaccination procedures, although showing a cortisol response, did not induce other major stress response in brain or pituitary, regardless the administration route. Other than main changes, the alteration of crhbp and gr suggests that these genes could play a relevant role in the feedback regulation of HPI axis after vaccination. In addition, from the results obtained in this work, it is also demonstrated that the immune system maintains a high activity in both brain and pituitary after vaccine injection.

Abstract
Objective To summarize the general characteristics and identification considerations of appraisal of post-traumatic epilepsy (PTE) in forensic clinical expertise. Methods Descriptive statistics were made on the general situations (age and sex), injury sites, PTE grading, clinical manifestations and blood drug concentrations of 30 cases of PTE. Chi-square test was performed on the differences of sex composition, age group incidences, injury sites, clinical manifestations and PTE grading. Fisher's exact probability method was used to test the differences in clinical manifestations and PTE grading of each site and the differences in PTE grading of different clinical manifestations. Results PTE occurred more frequently among 21 to 40 year olds, more in males than in females, and more frequently in the temporal lobe and frontal lobe. The clinical manifestations were mostly partial seizures and the PTE grading was mostly mild PTE. There were no statistical significance in the differences in distribution of clinical manifestations and PTE grading of injury sites (P>0.05). The difference in the PTE grading of different clinical manifestations had no statistical significance (P>0.05). The blood drug concentration of the three identified people did not reach the effective concentration, which affected the final identification opinion. Conclusion In the identification of PTE, in addition to strictly grasping the necessary factors of identification, such as the history of craniocerebral trauma, and epileptic seizures, it is also suggested that attention should be paid to the detection of blood drug concentration. Overall analysis and comprehensive evaluation should be made.

Abstract
The aim of the present study was to evaluate the effects of Lactobacillus rhamnosus GG (LGG; ATCC 53013) on growth performance and hepatotoxicity in calves fed a single dose of aflatoxin B1 (AFB1) and to investigate the absorption, distribution, and elimination of AFB1 and the hydroxylated metabolite aflatoxin M1 (AFM1) in rumen fluid, blood, and excretions. Twenty-four male Holstein calves were blocked for body weight and age and were randomly assigned to 1 of 3 treatment groups: (1) untreated control, (2) treated with 4.80 mg of AFB1 (AFB1 only), or (3) treated with 1 × 1010 cfu of LGG suspension and 4.80 mg of AFB1 (AFB1 plus LGG). The calves received LGG suspension in 50 mL of phosphate-buffered saline daily via oral administration for 14 d before and on the day they received a single oral dose of AFB1. Body weight was recorded at the beginning of the study (before LGG administration), at the day of AFB1 administration, and at the end of the trial. Rumen fluid, blood, urine, and feces samples were collected continuously for 96 h after AFB1 administration. Average daily gain (ADG) and plasma biochemical parameters were analyzed, and concentrations of AFB1 and AFM1 in the samples were determined for monitoring excretion pattern and toxicokinetics. The results showed that ADG was lower in AFB1-treated animals; LGG administration partially mitigated the decrease in ADG (0.85 ± 0.08 vs. 0.76 ± 0.18 kg of gain/d). The AFB1 treatment increased plasma aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase levels. Administration of LGG alleviated the AFB1-induced increase in plasma enzymes activity. The excretion patterns of AFB1 and AFM1 were surprisingly regular; toxins were rapidly detected in all samples after a single oral dose of AFB1, and the peak of toxins concentrations was sequentially reached in rumen fluid, plasma, urine, and feces (except AFM1 in rumen fluid), followed by an exponential decrease. The excretion curves showed that AFB1 and AFM1 concentrations were the highest in feces and urine, respectively. Administration of LGG decreased the concentrations of free AFB1 and AFM1 in rumen fluid and reduced the release of toxins into plasma and urine. Toxicokinetic parameters (except for the time of maximum concentration and the terminal half-life) were reduced by LGG administration. In conclusion, the absorption, distribution, and excretion of AFB1 and AFM1 were rapid in calves fed a single dose of AFB1. Urine was the main route for the excretion of AFM1, and the clearance pattern from the peak of concentration was well fitted by exponential decreasing function. Administration of LGG reduced the absorption of AFB1 in the gastrointestinal tract by increasing the excretion via the feces, thus alleviating the hepatotoxic effect of AFB1.

Abstract
OBJECTIVE The hypoxia-inducible factor-1α (HIF-1α) is a key factor for tumor cells adaptation to hypoxia. Studies have shown that under hypoxic conditions, HIF-1α expression was significantly increased in human tongue squamous cell carcinoma cells (Tca8113). This research aims to determine the exact mechanism of HIF-1α on the proliferation and apoptosis of Tca8113 cells. MATERIALS AND METHODS Tca8113 cells were cultured under normoxia and hypoxia. Real Time-PCR and Western blot were used to measure the expression levels of HIF-1α and TAZ. Under hypoxic condition, HIF-1α siRNA was transfected into Tca8113 cells. CCK8 was used to measure the proliferation of Tca8113 cells. Flow cytometry was used to detect apoptosis of Tca8113 cells. RESULTS Under hypoxic condition, the expression levels of HIF-1α and TAZ at both mRNA and protein levels were significantly increased (p <0.05). The downregulation of HIF-1α by siRNA significantly inhibited Tca8113 cells proliferation, increased their apoptosis, and reduced the expression level of TAZ. CONCLUSIONS Under hypoxic conditions, HIF-1α inhibits the proliferation and apoptosis of Tca8113 cells via the elevation of the Hippo signaling pathway.

Abstract
Objective: To quantitatively evaluate the quality of advanced modeled iterative reconstruction (ADMIRE) combined with 70 kVp and linear blending images in low dose dual energy (70 kVp/sn150 kVp) pulmonary angiography. Methods: A total of 74 cases with normal BMI underwent dual-source CT dual-energy pulmonary angiography with small amount of contrast medium (30 ml) from 2015 to 2017 from the First Affiliated Hospital of Zhengzhou University were randomly assigned to protocol Ⅰ(100 kVp/sn140 kVp) or protocol Ⅱ(70 kVp/sn150 kVp). 70 kVp+ ADMIRE (group 1), linear blending+ ADMIRE (group 2), 100 kVp+ SAFIRE (group 3) images were obtained. CT value and noise standard deviation (SD) of pulmonary arteries were measured in pulmonary trunk artery, left pulmonary artery and left superior pulmonary artery, then SNR and CNR were calculated. Radiation dose parameters (CTDIvol, DLP) were recorded. Results: CT values of pulmonary artery of group 1 were significantly higher than those in group 2 and 3 (both P<0.05). In group 2, SD value of pulmonary artery was lower than that of group 1 and 3(both P<0.05). SD value of pulmonary trunk and left pulmonary artery in group 1 was higher than that in group 3 (P<0.05), SD value of left superior pulmonary artery had no significant difference between group 1 and group 3 (P>0.05). SNR and CNR value in group 1 and group 2 had no statistical difference, but they were both higher than that in group 3 (both P<0.05). The effective dose of protocolⅠwas 46% lower than protocol Ⅱ. Conclusion: ADMIRE combined with 70 kVp and linear blending images are better than SAFIRE combined with 100 kVp images, and radiation dose is reduced.70 kVp/sn150 kVp with small amount of contrast medium (30 ml) is a feasible dual energy pulmonary artery scanning protocol.

Abstract
The contamination of inactivated vaccine with non-structural proteins (NSPs) leads to a high false-positive rate, which is a substantial barrier to accurately differentiate foot-and-mouth disease virus (FMDV)-infected animals from vaccinated animals. To address this problem, a new chemiluminescence immunoassay (CLIA) method was developed to detect antibodies targeting the two recombinant epitope-based proteins located in 3A and 3B. The 3Aepitp-3Bepitp CLIA exhibited a diagnostic sensitivity of 94.0% and a diagnostic specificity of 97.5% for the detection of serum samples (naïve bovines, n = 52, vaccinated bovines, n = 422, infected bovines, n = 116) from animals with known status. The CLIA method also had a concordance rate of 88.1% with the PrioCHECK FMDV NSP ELISA based on the detection of 270 serum samples from the field. Importantly, the 3Aepitp-3Bepitp CLIA produced no false-positives when used to detect FMDV in samples from bovines that had been vaccinated up to five times, and it was demonstrated a low false-positive rate when the bovines had been vaccinated up to ten (2.15%) and fifteen times (5.93%). Therefore, the 3Aepitp-3Bepitp CLIA detects FMDV in samples from frequently vaccinated bovines with high accuracy and represents an alternative method to differentiate FMDV-infected and vaccinated bovines.

Abstract
OBJECTIVE To investigate the anti-tumor effect and potential mechanism of dopamine combined with 5-FU in colon cancer. MATERIALS AND METHODS Babl/c F1 generation male mice (N = 60) were inoculated with mouse C26 colon cancer cells below the pit to construct colon cancer model. Tumor-bearing mice were then divided into 4 groups (N = 8 each): model control group, dopamine group, 5-FU group and dopamine combined with 5-FU group. Dopamine (100 mg/kg/d) was intraperitoneally injected into mice. The tumor-suppressing rate was calculated. Serum VEGF concentration was gained. Tumor tissues were subjected to HE staining. KLF2 expression was determined by immunohistochemical (IHC) staining. In vitro cultured C26 cells which treated with dopamine and cell apoptosis were analyzed by flow cytometry. RESULTS Compared with model control group, all treatment groups showed significantly decreased tumor weight and volume (p < 0.01), increased tumor necrosis (p < 0.05), reduced serum VEGF concentration (p < 0.05), and enhanced KLF2 expression in microvessels (p < 0.05). Combined treatment in terms of dopamine combined with 5-FU had the most pronounced effect compared with both dopamine and 5-FU treatment groups individually. Dopamine single t 5-FU and 5-FU groups showed a similar proportion of viable C26 cells (p > 0.05). CONCLUSIONS Dopamine exerts anti-tumor effects by modulating tumor vascular homeostasis through the KLF2 signaling pathway, and potentiates the treatment efficacy of anti-tumor drug 5-FU. Our study discovered clinical significance concerning the novelty of therapeutic strategy against colon cancer.

Abstract
An InP-based 2.1 μm InAs/In0.53Ga0.47As triangular quantum well laser grown with Bi surfactant has shown improved performance in comparison to the device with the same structure but grown without Bi surfactant. Under continuous-wave driving operation, the output light power is increased from 32.6 to 37.5 mW at the same injecting current of 850 mA at 200 K. The external differential and internal quantum efficiencies for the laser with Bi surfactant are 18.4% and 41%, respectively, which are correspondingly higher than 13.1% and 31% for the reference device. Furthermore, a decreased internal loss from 20.9 to 17.6 cm-1 for the Bi surfactant laser is also observed. These results suggest that Bi surfactant is promising for further enhancing performances of strained quantum well laser diodes.

Abstract
Objective: To investigate the diagnostic value of FibroTouch and FibroScan for the stage of primary biliary cirrhosis (PBC). Methods: A total of 66 PBC patients who visited our hospital from January 2014 to March 2016 were enrolled, and all the patients underwent liver biopsy and FibroTouch and FibroScan tests. Liver stiffness measurement (LSM) was used to assess fibrosis degree, and the receiver operating characteristic (ROC) curve was used to compare the cut-off values, sensitivities, and specificities of these two methods in determining fibrosis stage. The Spearman rank correlation test was used to investigate the correlation between FibroTouch and FibroScan values. Results: The correlation coefficients between FibroTouch or FibroScan values and fibrosis stage determined by liver biopsy were 0.904 and 0.880, respectively (both P < 0.01). The cut-off values of FibroTouch in the diagnosis of PBC with fibrosis stages of ≥S1, ≥S2, ≥S3, and ≥S4 were 6.25 kPa, 9.05 kPa, 11.75 kPa, and 18.95 kPa, respectively, with sensitivities of 89.7%, 94.7%, 80.0%, and 80.0% and specificities of 100%, 100%, 87.0%, and 100%, respectively; the cut-off values of FibroScan were 6.05 kPa, 8.85 kPa, 12.40 kPa, and 16.20 kPa, respectively, with sensitivities of 96.4%, 88.6%, 76.2%, and 100% and specificities of 77.8%, 100%, 86.4%, and 93.0%, respectively. There were no significant differences in the diagnostic performance between FibroTouch and FibroScan in determining fibrosis stage [≥S1 (P = 0.109), ≥S2 (P = 0.853), ≥S3 (P = 0.387), ≥S4 (P = 0.224)]. Conclusion: FibroTouch and FibroScan can be used as noninvasive diagnostic tools for the determination of fibrosis stage and the monitoring of disease progression in PBC patients and have good sensitivity and specificity.

Abstract
AKT1, also known as v-akt murine thymoma viral oncogene homolog 1, is involved in the regulation of cell-survival and anti-apoptotic activities, which may affect the pathogenesis of various cancers. However, the association between genetic variants of AKT1 and the risk of developing prostate cancer has not been investigated before. This study investigated the associations between three polymorphisms (rs1130214, rs3730358, and rs2494732) in AKT1 and the risk of development of prostate cancer in the Chinese Han population. Sequenom MassARRAY & iPLEX technology were used to genotype these polymorphisms in 493 Chinese Han patients with prostate cancer and 309 age-matched healthy individuals. Compared to the CC genotype of the rs3730358 polymorphism, the CT genotype of the same polymorphism was strongly associated with a decreased risk of prostate cancer (OR = 0.617, 95%CI = 0.390-0.976, P = 0.037). However, there was no significant difference between the allele frequency of the rs3730358 polymorphism and those of the other two polymorphisms (P > 0.05). Moreover, no significant difference was found in the haplotype analysis (P > 0.05). Our study found that the variant genotype CT of rs3730358 of AKT1 was associated with a decreased risk of prostate cancer, which suggested that this polymorphism could play an important role in the development of the disease.

Abstract
Lung cancer is one of the main causes of cancer-related mortality in males and females worldwide. A pleiotropic effect has been observed in the interleukin 18 gene (IL18); its effects include the activation of natural killer cell cytotoxicity and the promotion of the Th1 immune response through the alteration of the expression of interferon-γ and TNF-α in humans. IL18 is therefore involved in the elimination of tumor cells in the human body. We recruited 357 patients with non-small cell lung cancer (NSCLC) and 414 controls to evaluate the correlation between two genetic variations (IL18-607C/A and IL18-137G/C) and the pathogenesis of NSCLC. We used polymerase chain reaction-restriction fragment length polymorphism to genotype IL18-607C/A and IL18-137G/C. Statistical analysis revealed that individuals harboring the AA genotype of IL18-607C/A had an increased risk of NSCLC compared to those harboring the CC genotype (OR = 2.20, 95%CI = 1.30-3.74). Individuals expressing the A allele of IL18-607C/A had an elevated risk of developing NSCLC compared to those expressing the C allele (OR = 1.31, 95%CI = 1.06-1.62). In summary, our analysis shows that the IL18-607C/A genetic variation is related to the risk of NSCLC, whereas the IL18-137G/C variation is not. Therefore, the IL18-607C/A variation is related to the pathogenesis of NSCLC in the Chinese population studied.

Abstract
OBJECTIVE To investigate the clinical features of drug-induced autoimmune hepatitis (DIAIH) and its therapeutic strategies, and to provide a reference for early diagnosis and treatment of this disease and prevention of chronicity. METHODS The clinical data of 116 patients with drug-induced liver injury (DILI) or DIAIH confirmed by medical history, liver biochemistry, and liver biopsy were analyzed retrospectively. Among these patients, 13 had DIAIH and 103 had simple DILI (30 patients in the hepatocyte-type group and 73 in the cholestasis/mixed-type group). The population characteristics, major drugs inducing the diseases, clinical manifestations, liver biochemical parameters, liver pathological features, and clinical outcome were compared between groups. The Kruskal-wallis H test was used for comparison and the Mann-Whitney U test was used for comparison between any two groups. The chi-square test was used for comparison of categorical data, and the R×C chi-square test was used for comparison of rates between the three groups; in the case of significant differences, the R×C contingency table was used for comparison between any two groups. RESULTS The patients with DIAIH had a mean age of 53.54±8.28 years, and the mean age was 35.13±13.46 and 46.99±14.82 years for the hepatocyte-type group and cholestasis/mixed-type group, respectively. The disease was mainly induced by a combination of various drugs. The patients with DIAIH had significantly higher serum levels of alanine aminotransferase, aspartate aminotransferase, γ-glutamyltransferase, and alkaline phosphatase and a significantly higher positive rate of anti-nuclear antibody than those with DILI (all P < 0.05). In patients with DIAIH, the liver pathological features and the features of response to treatment were as follows: obvious interface hepatitis, proliferation of small bile ducts, and mixed inflammatory cell infiltration in the portal area, including eosinophils and plasma cells, and the short-term corticosteroid therapy had a good therapeutic effect. CONCLUSION DIAIH has a low incidence and is more common in the female population, with the features of tissue injury in both DILI and autoimmune hepatitis. The short-term corticosteroid therapy can prevent disease progression and reduce chronicity.

Abstract
Sacral nerve stimulation (SNS) is an alternative surgical approach to alleviate fecal incontinence and constipation. This study aimed to explore the effects and underlying mechanisms of SNS with acupuncture on gut transit time and colon c-kit protein expression in rats with slow transit constipation (STC). Fifty Sprague-Dawley rats were randomly divided into five groups: blank control, SNS, Mosapride, sham SNS, and STC model control group. The STC model was established by subcutaneous injection of morphine. Each group was treated over a 15-day period. Gut transit time was measured 1 day before the treatment started and after 5, 10, and 15 days of treatment. After the 15-day treatment, animals were sacrificed and colonic tissues were collected for analysis of c-kit protein expression, using western blot analysis. We found significant differences in gut transit time in the SNS group compared with the Mosapride group after 5 (P = 0.001) and 10 (P = 0.004) days of treatment. After 15 days of treatment, there were no differences in gut transit time among the SNS, Mosapride, and blank control groups. However, significant differences were observed when comparing the SNS and Mosapride groups with the STC model and sham SNS groups. A decreased c-kit protein expression was observed in the STC model control, sham SNS, and Mosapride groups, compared with the SNS group (P = 0.001). Our data indicate that SNS can decrease gut transit time and increase the expression of c-kit protein in rats with STC to improve colon transit function.

Abstract
OBJECTIVE The present study aims to investigate the relationship between expression of inflammatory cytokines in the peripheral blood and the severity of depression and anxiety in patients with Parkinson's disease (PD). PATIENTS AND METHODS Between January 2012 and December 2015, 62 PD patients admitted to our institution were included in the PD group, and 62 healthy subjects seeking health check-up at our institution during the same period of time were enrolled in the control group. Levels of inflammatory cytokines, including IL-1b, IL-6, interferon-g (INF-g), hypersensitive C-reactive protein (hsCRP) and soluble IL-2 receptor (sIL-2R), were measured by using Enzyme-linked immunosorbent assay (ELISA). Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) were used to assess the severity of depression and anxiety, respectively. RESULTS A total of 124 subjects were included into PD group and control group, 62 for each. No significant differences were observed in the gender, age, body mass index (BMI), smoking history and alcohol history between two groups (p > 0.05). Levels of IL-1b, IL-6, TNF-a, hsCRP and sIL-2R were significantly higher in patients of PD group than those in the control group (p < 0.05). HAMD and HAMA scores in PD group were significantly higher than those in the control group [(22.74 ± 6.34), (20.90 ± 5.86) vs. (2.17±3.46), (3.79 ± 3.55), p < 0.05]. HAMD and HAMA scores were positively correlated with the levels of TNF-a, hsCRP and sIL-2R in the peripheral blood of PD patients (p < 0.05). CONCLUSIONS Expression of inflammatory cytokines are elevated in the peripheral blood of PD patients, and the severity of depression and anxiety is correlated with levels of TNF-a, hsCRP and sIL-2R in the peripheral blood of these patients.

Abstract
OBJECTIVE To investigate the clinicopathological features of different stages of primary biliary cirrhosis (PBC), and to provide a basis of evidence-based medicine for early identification and effective treatment of this disease. METHODS A total of 130 patients with pathologically confirmed PBC and complete clinical data were enrolled and divided into early-stage group and late-stage group based on pathological results. A retrospective analysis was performed for patients' general information, clinical manifestations, laboratory examinations, and pathological changes. RESULTS The PBC patients had a mean age of 43.5±7.1 years, with middle-aged female patients accounting for 89%. The most common symptom was fatigue, followed by jaundice, pruritus, and abdominal distension in the late stage. Of all patients, 11.5% were complicated by autoimmune disease. The level of aminotransferases tended to decrease with the progression of PBC and showed no significant differences between the two groups (P > 0.05). Most patients showed an increase in serum bilirubin, mainly direct bilirubin; serum total bilirubin and direct bilirubin tended to increase with disease progression and showed significant differences between the two groups (P < 0.01). The patients showed increases in the serum levels of alkaline phosphatase (ALP) andγ-glutamyl transpeptidase (GGT), but with the disease progression, the serum level of ALP increased and that of GGT decreased; the serum levels of ALP and GGT showed no significant differences between the early- and late-stage groups (P > 0.05). The positive rate of antimitochondrial antibody was 85%. The histopathological changes of PBC included severe lesions in the portal area and surrounding areas and slight lobular lesions. In the early stage, there were injuries of the interlobar bile ducts, proliferation of small bile ducts, aggregation and invasion of mononuclear cells in surrounding tissues, and the formation of lymphoid follicle-like structure; in the late stage, there were fibrotic expansion of the portal area, formation of fibrous septa and pseudolobuli, and even liver cirrhosis. CONCLUSION PBC is commonly seen in middle-aged women and has an insidious onset. Early- and late-stage PBC have their own clinicopathological features. As for patients with no characteristic changes in serological test, liver biopsy should be performed to give a confirmed diagnosis and avoid missed diagnosis and misdiagnosis.

Abstract
OBJECTIVE The aim of the present study is to investigate expressions of inflammatory cytokines and their relationship with cerebral edema in the patients with acute basal ganglia hemorrhage. PATIENTS AND METHODS Between January 2015 and March 2016, 94 patients with acute basal ganglia hemorrhage admitted to our institution were included in the present study. Serum levels of interleukin (IL)-4, IL-6, IL-8 and IL-10 were measured using enzyme-linked immunosorbent assay (ELISA), and conditions of cerebral edema were evaluated using head CT upon admission, 1d after admission and 3d after admission, respectively. RESULTS Serum levels of IL-4, IL-6 and IL-8 peaked 1d after admission and decreased 3d after admission with statistical significance (p <0.05); the IL-10 level was continuously increased after admission and peaked 3 days after admission with statistical significance (p<0.05). Cerebral edema was not observed in any of these patients upon admission, while occurred with a maximal edema volume 1 day after admission and the volume decreased 3 days after admission with statistical significance (p <0.05). Correlation analysis showed that levels of IL-4, IL-6 and IL-8 were positively correlated with severity of cerebral edema (r=0.324, 0286, 0.305, p <0.05 respectively), whereas IL-10 level was negatively correlated with severity of cerebral edema (r=-0.336, p <0.05). CONCLUSIONS Serum levels of IL-4, IL-6 and IL-10 are positively correlated while the IL-10 level is negatively correlated with the severity of the cerebral edema in patients with acute basal ganglia hemorrhage.

Abstract
OBJECTIVE G protein-coupled receptor, family C, group 6, member A, (GPRC6A) is a prostate cancer (PCa) susceptibility gene and has been shown to regulate PCa progression. However, its role in PCa metastasis is largely unknown. The aim of this study was to confirm the association between GPRC6A and aggressive PCa in a case-control analysis, and to explore the function of GPRC6A in PCa metastasis in vitro. PATIENTS AND METHODS The association of 14 single nucleotide polymorphisms (SNPs) of GPRC6A and linked to GPRC6A were evaluated with PCa risk and aggressive PCa in 916 subjects. Metastasis behavior was determined in GPRC6A knockdown PC3 cells, and the expressions of matrix metalloproteinase (MMP)2 and MMP9 were detected. Bone transcription factor runt-related transcription factor 2 (RUNX2) and epithelial-mesenchymal transition (EMT) marker genes were examined in the GPRC6A overexpression PC3 cells. RESULTS Among the 14 SNPs tested in PCa patients and controls, 4 were associated with aggressive PCa (p = 0.032-0.037, odds ratio = 1.38-1.41). Both the migration and invasion abilities were reduced in PC3 cells that were transiently transfected with GPRC6A short interfering RNA (siRNA). The GPRC6A knockdown cells showed reduced activity levels of MMP2 and MMP9. Furthermore, RUNX2, EMT and ERK signaling were shown to be up-regulated in GPRC6A overexpression cells. CONCLUSIONS These findings suggest that GPRC6A is associated with aggressive PCa. GPRC6A knockdown inhibits the PCa cells migration and invasion, and GPRC6A overexpression promotes the EMT. It is suggested that GPRC6A may serve as a potential therapeutic target for metastatic PCa.

Abstract
Post traumatic epilepsy (PTE) refers to the epileptic seizures after traumatic brain injury. Organic damage can be found by imaging examination, and abnormal electroencephalogram can be detected via electroencephalogram examination which has the similar location of the brain injury. PTE has the characteristics of low incidence, absence of case reports, and easy to exaggerate the state of illness, which add difficulties to the forensic identification. This paper reviews the status of epidemiology, pathogenesis, clinical treatment and forensic identification for PTE.

Abstract
OBJECTIVE To explore clinical effects of Tirofiban treatment on patients with high-risk non-ST-segment elevation acute coronary syndrome (NSTE-ACS) after percutaneous coronary intervention (PCI). PATIENTS AND METHODS 107 patients with high-risk NSTE-ACS after PCI were selected and were divided into two groups. One group of 56 patients was treated with Tirofiban and a second group of 51 patients was taken as control. The occurrence conditions of creatine kinase-myoglobin (CK-MB), cardiac troponin1 (cTnI) level, hemorrhage incidents and major adverse cardiac events (MACE) incidents after treatments were compared. RESULTS After 24 h operation, CK-MB and cTnI level in Tirofiban group were both significantly lower than those in control group (p < 0.05), while the difference of hemorrhage incidents between two groups is of no statistical significance (p < 0.05); and the differences in overall occurrence rate of MACE incidents and the occurrence rate of angina pectoris after infarct between two groups were statistically significant (p < 0.05). CONCLUSIONS Tirofiban could improve the blood supply condition of hearts of patients with high-risk NSTE-ACS after emergent PCI, lower the occurrence rate of MACE incidents, and decrease the risk of hemorrhage.

Abstract
In this work, the influence of Pb and Bi atoms on the anti-corrosion behavior of the oxide film (Fe3O4) formed on steel surface is investigated based on first-principles calculations. Through calculations of the formation energies, we find that Pb and Bi atoms can promote the formation of point defects, such as interstitial atoms and vacancies in Fe3O4. Besides, the effects of the concentration of Pb (or Bi) and pressure on the formation of these defects are also studied. Our results depict that a high density of Pb (or Bi) and compression pressure can promote the formation of defects in Fe3O4 significantly. Furthermore, the energy barriers for Pb and Bi atom migration in Fe3O4 are also estimated using the climbing image nudge elastic band (CI-NEB) method, which implies that Pb and Bi can diffuse more easily in Fe3O4 compared to Fe. Our results reveal the underlying mechanism of how Pb and Bi influence the anti-corrosion ability of oxide films in an accelerate driven system (ADS). It is instructive for improving the corrosion resistance of the oxide films in the ADS.

Abstract
OBJECTIVE To determine the expression of circular RNA (circRNA) in blood corpuscles of pregnant women before 20 weeks of pregnancy and to create a new model to identify the performance of circRNA combined with protein factors for the early diagnosis of pre-eclampsia (PE). DESIGN Nested case-control study. SETTING University medical centre, Guangzhou, China. POPULATION A total of 1400 pregnant women recruited between 8 and 20 weeks of gestation. In all, 41 women with PE were included in the study, and were matched with 41 normally pregnant women based on maternal age and gestational age at same-size ratio. METHODS The samples were analysed using a human circRNA microarray in the discovery phase, then the circRNA and the plasma protein factor endoglin (ENG) were validated. Finally we combined ENG with circRNA to create a new early prediction model for PE. MAIN OUTCOME MEASURES Early changes of circRNA and ENG in PE. RESULTS The circ_101222 levels in blood corpuscles of patients with PE were significantly higher than those in corresponding healthy women (P < 0.001). Using ENG in combination with circ_101222 resulted in a sensitivity of 0.7073, a specificity of 0.8049, and overall area under the curve of 0.876 (95% confidence interval 0.816-0.922) for the prediction of PE. CONCLUSION CircRNA and plasma proteins may have some predictive value for PE (such as circ_101222 and ENG). The performance of each of these factors may be strengthened when plasma proteins are used in combination with circRNA. The results are preliminary and need to be validated in larger studies and other populations. TWEETABLE ABSTRACT Plasma protein endoglin in combination with circ_101222 strengthened the predictive power for pre-eclampsia.

Abstract
The supplementation of livestock feed with animal protein is a present cause for public concern, and plant protein shortages have become increasingly prominent in China. This conflict may be resolved by fully utilizing currently available sources of plant protein. We estimated the rumen degradability and the small intestinal digestibility of the amino acids (AA) in rapeseed meal (RSM), soybean meal (SBM), sunflower seed meal (SFM) and sesame meal (SSM) using the mobile nylon bag method to determine the absorbable AA content of these protein supplements as a guide towards dietary formulations for the dairy industry. Overall, this study aimed to utilize protein supplements effectively to guide dietary formulations to increase milk yield and save plant protein resources. To this end, we studied four cows with a permanent rumen fistula and duodenal T-shape fistula in a 4×4 Latin square experimental design. The results showed that the total small intestine absorbable amino acids and small intestine absorbable essential amino acids were higher in the SBM (26.34% and 13.11% dry matter [DM], respectively) than in the SFM (13.97% and 6.89% DM, respectively). The small intestine absorbable Lys contents of the SFM, SSM, RSM and SBM were 0.86%, 0.88%, 1.43%, and 2.12% (DM basis), respectively, and the absorbable Met contents of these meals were 0.28%, 1.03%, 0.52%, and 0.47% (DM basis), respectively. Among the examined food sources, the milk protein score of the SBM (0.181) was highest followed by those of the RSM (0.136), SSM (0.108) and SFM (0.106). The absorbable amino acid contents of the protein supplements accurately reflected protein availability, which is an important indicator of the balance of feed formulation. Therefore, a database detailing the absorbable AA should be established.

Abstract
OBJECTIVE To investigate the differences of the B-type natriuretic peptide (BNP) levels in serum or plasma of the STEMI patients with different infarction sites. To explore the relationship between the BNP level and the short-term prognosis in patients with ST-segment elevation myocardial infarction (STEMI). PATIENTS AND METHODS A total of 216 STEMI patients were enrolled in this study from June 2012 to June 2014. All patients received coronary angiography (CAG). Based on electrocardiography (ECG) and CAG results, patients were divided into three groups. Group A included 80 patients with anterior/lateral wall myocardial infarction, group B included 76 patients with inferior/posterior wall myocardial infarction and group C included 60 patients with right ventricular myocardial infarction. We enrolled 53 patients with normal CAG results as Group D. BNP levels were compared among these groups. and according to BNP levels, all patients were subdivided into normal BNP group (< 100 ng/mL, n = 53), mild-higher BNP group (100-400 ng/mL, n = 105) and marked-higher BNP group (≥ 400 ng/mL, n = 58). The occurrence of major adverse cardiovascular events (MACE) including secondary heart failure, severe arrhythmia, post-infarction angina, recurrent myocardial infarction, and cardiac death within 6 months after disease onset were assessed. RESULTS BNP levels showed a gradually decreasing trend in groups A, B, C and D (p < 0.05). Significant differences in left ventricular ejection fraction (LVEF) were found among normal BNP group, mild-high BNP group and marked-higher BNP group (p < 0.05). The MACE occurrence presented no statistical differences between normal BNP group and mild-higher BNP group (p > 0.05). The MACE prevalence in marked-higher BNP group was significantly higher than normal BNP group and mild-higher BNP group (p < 0.05). CONCLUSIONS BNP levels can be used as a clinical indicator to predict short-term prognosis in STEMI patients.

Abstract
BACKGROUND Anti-cancer effect of metformin on different kinds of lung cancer has been studied frequently. However, the association between metformin and the prognosis of lung cancer in type 2 diabetes patients is still controversial. METHODS An electronic search was conducted using PubMed/Medicine, EMBASE and Cochrane library databases. Statistical analyses were carried out using either random-effects or fixed-effects models according to the heterogeneity examined by I (2) statistics. RESULTS Six studies involving 2350 patients were included in the current meta-analysis. In all, the pooled HR of overall survival (OS) was 0.90 (95 % CI 0.84-0.96; P = 0.003). Sub-group analysis showed that when stratified by region the HR of OS was 0.52 (95 % CI 0.31-0.87; P = 0.012) and 0.86 (95 % CI 0.67-1.11, P = 0.361) for Asian and Western countries. When stratified by study design, the HR of OS was 0.78 (95 % CI 0.52-1.15, P = 0.206) and 0.82 (95 % CI 0.59-1.16, P = 0.264) for cohort and medical data-based studies. When stratified by lung cancer subtype, HR of OS was 0.52 (95 % CI 0.31-0.87; P = 0.012), 1.06 (95 % CI 0.51-2.19; P = 0.878) and 0.82 (95 % CI 0.59-1.16; P = 0.264) for SCLS, NSCLC and non-divided subtypes, respectively. CONCLUSION Metformin use may associate with a good prognosis in lung cancer patients with type 2 diabetes but the effect was modest. However, it could achieve benefits in a selective sub-group of lung cancer patients especially in SCLC patients from Asian. Further studies are warranted to confirm this efficacy.

Abstract
Four methods were adopted, including the mobile nylon bag (MNB) method, modified three-step in vitro (MTS) method, original three-step in vitro (OTS) method, and acid detergent insoluble nitrogen (ADIN) estimating method, to evaluate the intestinal digestibility of rumen undegradable protein (DRUP) of 10 types of concentrates and 7 types of roughages. After correlation analysis to determine the DRUP values using the MNB, MTS, OTS, and ADIN methods, the study aimed to find out appropriate methods to replace the MNB method due to its disadvantages such as high price, long time period, and use of a duodenal T-fistula. Three dairy cows with a permanent ruminal fistula and duodenal T-fistula were used in a single-factor experimental design. The results showed that the determined DRUP values using the MNB method for soybean meal, cottonseed meal, rapeseed meal, sunflower meal, corn germ meal, corn, rice bran, barley, wheat bran, corn fiber feed, Alfalfa (Zhao dong), Alfalfa (Long mu 801), Alfalfa (Long mu 803), grass (North), Grass (Inner Mongolia), corn silage and corn straw were 98.13%, 87.37%, 88.47%, 82.60%, 75.40%, 93.23%, 69.27%, 91.27%, 72.37%, 79.03%, 66.72%, 68.64%, 73.57%, 50.47%, 51.52%, 54.05%, and 43.84%, respectively. The coefficient of determination (R2 = 0.964) of the results between the MTS method and the MNB method was higher than that (R2 = 0.942) between the OTS method and the MNB method. The coefficient of determination of the DRUP values of the concentrates among the in vitro method (including the MTS and OTS methods) and the MNB method was higher than that of the roughage. There was a weak correlation between the determined DRUP values in concentrates obtained from the ADIN method and those from the MNB method, and there was a significant correlation (p<0.01) between the determined DRUP values of the roughage obtained from the MNB method and those obtained from ADIN method. The DRUP values were significantly correlated with the nutritional ingredients of the feeds. The regression equation was DRUP =100.5566+0.4169CP − 0.4344SP − 0.7102NDF − 0.7950EE (R2 = 0.8668, p<0.01; CP, crude protein; SP, soluble protein; NDF, neutral detergent fiber; EE, ether extract). It was concluded that both the MTS method and the OTS may suitable to replace the MNB method for determining the DRUP values and the former method was more effective. Only the ADIN method could be used to predict the values of the roughages but conventional nutritional ingredients were available for all of the samples’ DRUP.
