RESUMEN
Objective: To evaluate the safety and efficacy of endovascular thrombectomy (EVT) in acute anterior circulation large vessel occlusive stroke (ALVOS) and explore the related influencing factors for prognoses in patients with low Alberta Stroke Program Early Computed Tomography Score (ASPECT). Methods: Patients with acute ALVOS who underwent EVT in Yijishan Hospital of Wannan Medical College from January 2019 to June 2022 were sequentially enrolled. (1) Patients were divided into a low ASPECT group (0-5) and a non-low ASPECT group (6-10), and the differences between the two groups were compared with respect to incidence of perioperative complications and good prognosis rate [modified Rankin scale (mRS) score≤2] 90 days after onset. (2) According to the prognoses 90 days after onset, the low ASPECT group was divided into the good prognosis (mRS score≤2) and poor prognosis (mRS score>2) subgroup. Univariate analysis and multivariate logistic regression analysis were used to investigate the independent risk factors for prognoses of the low ASPECT patients after EVT. Results: A total of 582 patients [age 26-94(69±11) years, 345 male patients (59.3%)] were enrolled for analysis. The baseline ASPECT score was 8 (7, 10), and the baseline NIHSS score was 14 (11, 18). Among them, 102 (17.5%) patients were in the low ASPECT score group and 480 (82.5%) patients were in the non-low ASPECT score group. In the total cohort, patients in the low ASPECT score group had a higher incidence of symptomatic intracranial hemorrhage, lower 90-day good prognosis rate, and higher 90-day mortality rate. Further, propensity score matching statistical analysis showed that patients in the low ASPECT score group had a significantly higher incidence of malignant brain edema after EVT treatment (40.0% vs. 17.6%, χ2=9.13, P=0.003), and a significantly lower 90-day good prognosis rate (24.7% vs. 41.6%, χ2=4.96, P=0.026), but there was no significant difference in the incidence of symptomatic intracranial hemorrhage and 90-day mortality between the two groups (40.3% vs. 26.0%, χ2=3.55, P=0.060). Among 102 patients with low ASPECT score, 22 (21.6%) patients had good prognosis and 80 (78.4%) had poor prognosis. Multivariate logistic regression analysis showed that history of atrial fibrillation (OR=4.478, 95%CI 1.186-16.913, P=0.027) was an independent risk factor for poor prognosis of EVT in patients with low ASPECT score, while good collateral circulation (grade 2 vs. grade 0: OR=0.206, 95%CI 0.051-0.842, P=0.028) was a protective factor for good prognosis of EVT in patients with low ASPECT score. Conclusions: Although the 90-day good prognosis rate of EVT treatment for patients with low ASPECT score was lower than that of the non-low ASPECT group, 21.6% patients still benefitted from EVT treatment, especially patients with non-atrial fibrillation and good collateral circulation. Future studies involving more patients are needed to validate our observations.

Objective: To evaluate the long-term outcomes, failure patterns and prognostic factors of definitive radiotherapy in patients with cervical esophageal carcinoma (CEC). Methods: We retrospectively reviewed the clinical data of 148 CEC patients who treated with definitive radiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2001 to December 2017. The median radiation dose was 66 Gy (59.4-70 Gy) and 33.1% of patients received concurrent chemotherapy. The Kaplan-Meier method was used to calculate survival rates. The log rank test was used for survival comparison and univariate prognostic analysis. The Cox model was used for multivariate prognostic analysis. Results: The median follow-up time was 102.6 months. The median survival time, 2- and 5-year overall survival (OS) were 22.7 months, 49.9% and 28.3%. The median, 2- and 5-year progression-free survival were 12.6 months, 35.8% and 25.8%. The 2- and 5-year locoregional recurrence-free survival were 59.1% and 50.8%. The 2- and 5-year distant metastases-free survival were 74.6% and 65.9%. Multivariate analysis showed that EQD(2)>66 Gy was the only independent prognostic indicator for OS (P=0.040). The median survival time and 5-year OS rate significantly improved in patients who received EQD(2)>66 Gy than those who received≤66 Gy (31.2 months vs. 19.2 months, 40.1% vs. 19.1%, P=0.027). A total of 87 patients (58.8%) developed tumor progression. There were 50 (33.8%), 23 (15.5%) and 39 (26.4%) patients developed local, regional recurrence and distant metastases, respectively. Eleven patients (7.4%) underwent salvage surgery, and the laryngeal preservation rate for entire group was 93.9%. Conclusions: Definitive radiotherapy is an effective treatment for cervical esophageal carcinoma with the advantage of larynx preservation. Local recurrence is the major failure pattern. EQD(2)>66 Gy is associated with the improved overall survival.

Objective: To summarize survival outcomes and prognostic factors in esophageal cancer (EC) patients treated with intensity-modulated radiotherapy (IMRT). Methods: A retrospective analysis was performed on the clinical and follow-up data of 1 637 patients with EC who were admitted to our hospital from January 2005 to December 2017 and met the inclusion criteria.The 5-year overall survival (OS), progression-free survival (PFS) and pattern of recurrence were analyzed. The Kaplan-Meier method was used to calculate survival rates, Log-rank test for univariate analysis and Cox method for multivariate analysis were used to detect survival difference. Results: 1-year, 3-year and 5-year OS and PFS of the entire group were 65.9% and 45.8%, 34.2% and 25.0%, 27.0% and 18.5%, respectively. Median OS and PFS were 19.4 months (95% CI=18.0-20.7 months) and 10.4 months (95% CI=9.3-11.3 months), respectively. Univariate analysis showed that the sex, KPS, tumor location, T stage, N stage, M stage, TNM stage, radiation dose and treatment modality were prognostic factors for 5-year OS and PFS of EC patients (P<0.05). Multivariate analysis indicated that the sex, KPS, TNM stage, radiation dose and treatment modality were independent prognostic factors for 5-year OS and PFS (P<0.05). Conclusions: EC patients treated with IMRT can obtain a promising survival. The sex, KPS, TNM stage, radiation dose and treatment modality are independent prognostic factors for prognosis.

Objective: To analyze the survival benefits and treatment related toxic effects of simultaneous integrated boost intensity-modulated radiotherapy (SIB-RT) for non-operative esophageal squamous cell carcinoma patients. Methods: The data of 2 132 ESCC patients who were not suitable for surgery or rejected operation, and underwent radical radiotherapy from 2002 to 2016 in 10 hospitals of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG) were analyzed. Among them, 518 (24.3%) cases underwent SIB (SIB group) and 1 614 (75.7%) cases did not receive SIB (No-SIB group). The two groups were matched with 1â¶2 according to propensity score matching (PSM) method (caliper value=0.02). After PSM, 515 patients in SIB group and 977 patients in No-SIB group were enrolled. Prognosis and treatment related adverse effects of these two groups were compared and the independent prognostic factor were analyzed. Results: The median follow-up time was 61.7 months. Prior to PSM, the 1-, 3-, and 5-years overall survival (OS) rates of SIB group were 72.2%, 42.8%, 35.5%, while of No-SIB group were 74.3%, 41.4%, 31.9%, respectively (P=0.549). After PSM, the 1-, 3-, and 5-years OS rates of the two groups were 72.5%, 43.4%, 36.4% and 75.3%, 41.7%, 31.6%, respectively (P=0.690). The univariate survival analysis of samples after PSM showed that the lesion location, length, T stage, N stage, TNM stage, simultaneous chemoradiotherapy, gross tumor volume (GTV) and underwent SIB-RT or not were significantly associated with the prognosis of advanced esophageal carcinoma patients who underwent radical radiotherapy (P<0.05). Cox model multivariate regression analysis showed lesion location, TNM stage, GTV and simultaneous chemoradiotherapy were independent prognostic factors of advanced esophageal carcinoma patients who underwent radical radiotherapy (P<0.05). Stratified analysis showed that, in the patients whose GTV volume≤50 cm(3), the median survival time of SIB and No-SIB group was 34.7 and 30.3 months (P=0.155), respectively. In the patients whose GTV volume>50 cm(3), the median survival time of SIB and No-SIB group was 16.1 and 20.1 months (P=0.218). The incidence of radiation esophagitis and radiation pneumonitis above Grade 3 in SIB group were 4.3% and 2.5%, significantly lower than 13.1% and 11% of No-SIB group (P<0.001). Conclusions: The survival benefit of SIB-RT in patients with locally advanced esophageal carcinoma is not inferior to non-SIB-RT, but without more adverse reactions, and shortens the treatment time. SIB-RT can be used as one option of the radical radiotherapy for locally advanced esophageal cancer.

The aim of this study was to determine the effect of calcium propionate (CaP) on rumen microbiota, fermentation indicators, and weight gain in calves both pre- and postweaning. Twenty-four newborn calves were randomly divided into 4 groups (2 × 2 factorial treatment arrangement): either pre- (90 d) or postweaning (160 d), and either without or with dietary CaP supplementation (5% dry matter). The CaP supplementation increased the body weight and rumen weight of the calves and lowered NH3-N concentration in the rumen. Microbiota composition was characterized by sequencing the amplicons of the bacterial and archaeal 16S rRNA genes. The CaP supplementation decreased the relative abundance of the phylum Bacteroidetes but tended to increase that of Proteobacteria. In addition, CaP supplementation decreased the diversity of bacteria and archaea in the rumen compared with the calves fed the control diet. Linear discriminant analysis of the rumen microbiota revealed that Succinivibrionaceae and Methanobrevibacter were enriched in the CaP group postweaning. A correlation was also present between the acetate to propionate ratio and the species that acted as co-occurrence network hubs, including Succiniclasticum, Treponema, and Megasphaera. In conclusion, CaP supplementation can improve body weight gain and rumen growth and alter the ruminal microbiota in calves both pre- and postweaning.

Objective: To evaluate the tolerability and short-term efficacy of chemo-radiotherapy in 125 patients with stage â ¡B-â £A esophageal carcinoma after radical resection. Methods: We retrospectively evaluated the rate of completion, toxicity and survival of patients undergoing adjuvant concurrent chemo-radiotherapy after radical resection of esophageal carcinoma from January 2004 to December 2014 in our institution. The survival rate was determined by the Kaplan-Meier method and analyzed using the log-rank test. Multivariate prognostic analysis was performed using the Cox proportional hazard model. Results: 122 patients received more than 50 Gy dose (97.6%). A total of 52 patients received more than 5 weeks chemo-radiotherapy (41.6%), while 73 patients underwent only 1-4 weeks (58.4%). The median following up was 48.4 months. 8 patients lost follow up (6.4%). The 1-year and 3-year overall survival rate were 91.6% and 57.0%, respectively, with a median survival time of 64.4 months. The 1-year and 3-year disease free survival rate were 73.2% and 54.3%, respectively, with a median disease free survival time of 59.1 months. The most common acute complications associated with chemo-radiotherapy were myelosuppression, radiation esophagitis and radiation dermatitis, the majority of which were Grade 1-2. Of the 125 patients, there were 59 cases of recurrence, including 23 cases with local regional recurrence, 26 cases with hematogenous metastasis, and 8 cases with mixed recurrence. Univariate analysis showed that the numbers of concurrent chemotherapy was associated with the overall survival (P=0.006). But receiving more than 5 weeks was not the prognostic factor compared to 1 to 4 weeks chemotherapy (P=0.231). Multivariate analysis showed that only the numbers of concurrent chemotherapy was an independent prognostic factor (P=0.010). Conclusions: Postoperative radiotherapy concurrent with weekly chemotherapy could improve the overall survival and decrease the recurrence for stage â ¡B-â £A esophageal carcinoma after radical resection. However, the completion rate of chemotherapy was low, so it was necessary to explore reasonable regimens to improve the completion rate and carry out prospective randomized controlled trial.

Objective: The role of planned neoadjuvant radiotherapy or chemoradiotherapy in the non-radical resection of esophageal squamous cell carcinoma was unclear. The study aimed to evaluate their therapeutic effect and analyze the prognostic factors. Methods: We retrospectively analyzed the clinical data of locally advanced esophageal squamous cell carcinoma who received neoadjuvant radio therapy (33 patients) and concurrent chemoradiotherapy (119 patients) from January 2004 to December 2016 in our single-institution database.The survival rates were calculated by Kaplan-Meier method. The prognostic factors were analyzed by using Log rank test and Cox proportional hazards model. Results: The median follow-up was 29.8 months. One hundred and one patients survived more than 3 years. The rates of overall survival (OS) and disease-free survival (DFS) at 3 years were 63.9% and 55.6%, respectively.The rates of complete, partial and minimal pathological response of the primary tumor were 50.3%, 38.4%, 11.3%, the corresponding 3-year OS were 75.5%, 57.4%, 27.3% (P<0.001) and 3-year DFS were 72.0%, 44.7%, 17.6% (P<0.001), respectively.The postoperative lymph node metastasis rate was 27.0%. The 3-year OS and DFS of the lymph node positive group was 45.6% and 32.8%, significantly lower than 70.8% and 63.7% of the negative group (both P<0.001). The 3-year OS and DFS of pathologic stage â , â ¡, â ¢A, â ¢B and â ¥ A were 76.2%, 57.4%, 64.7%, 35.0%, 33.3% (P<0.001) and 70.1%, 49.3%, 41.2%, 22.1%, 33.3% (P<0.001), respectively.The operation-related mortality was 3.3%. Multivariate analysis showed that chest pain, postoperative respiratory failure, pathological differentiation, more than 15 lymph node dissection and ypTNM stage were the independent prognostic factors of OS (P<0.05 for all). Conclusions: The planned neoadjuvant radiotherapy or chemoradiotherapy for the non-radical resection of advanced esophageal squamous cell carcinoma could result in favorable survival. The chest pain, postoperative respiratory failure, pathological differentiation, the number of lymph node resection and ypTNM stage are the independent prognostic factors of the prognosis of these patients.

Objective: The aim of this retrospective study was to evaluate the prognostic significance of pretreatment Neutrophil-to-Lymphocyte Ratio(NLR) in locally advanced non-small cell lung cancer(NSCLC) patients treated with thoracic radiotherapy. Methods: We retrospectively analyze 420 patients who received thoracic radiotherapy alone, sequential chemoraiotherapy or concurrent chemoradiotherapy for locally advanced stage NSCLC from January 2007 to December 2010 of our hospital. The patients were divided into two groups (high NLR group and low NLR group) with appropriate cutoff point using the receiver operating characteristic (ROC) curve method. The survival curve was established by Kaplan-Meier method. The Log-rank test was used to compare the survival of the two NLR groups and the multivariate analysis was carried out by Cox regression model. Results: Among the 420 patients, 99 received radiotherapy alone, 139 received sequential chemoradiotherapy and 182 received concurrent chemoradiotherapy. 345 patients died and 75 were still alive. The median follow-up time was 5.2 years and the median overall survival was 22 months. The cut-off value of pretreatment NLR was 2.1. The 5-year PFS and OS rates in high NLR group and low NLR group were 10.6% vs 15.7% (P=0.033) and 15.5% vs 22.7% (P=0.012). Multivariate analysis confirmed that pretreatment NLR (hazard ratio 1.06, P=0.041) was independent prognostic factor of OS. Conclusions: Our study revealed that the pretreatment NLR is the independent prognostic factor of OS in patients with locally advanced stage NSCLC treated with thoracic radiotherapy. However, NLR is still greatly influenced by patient's condition and treatment which needs further research.

OBJECTIVE: To analyze the outcome and prognostic factors of IMRT-based preoperative neoadjuvant chemoradiotherapy in patients with thoracic esophageal squamous cell carcinoma (ESCC). METHODS: Clinical data of 62 patients with thoracic ESCC who received IMRT-based neoajuvant chemoradiotherapy from January 2009 to January 2015 were retrospectively analyzed. The radiation therapy was given 1.8-2 Gy/fraction per day over 5 days per week with 6 MV X-rays, and then all patients underwent esophagectomy and lymphadenectomy. RESULTS: Among the 62 patients, the R0 resection rate was 96.8%. Twenty (32.3%) patients achieved pCR and 56 (90.3%) cases got down-staging. Grade â ¢ marrow suppression and esophagitis were seen in 8 (12.9%) and 2 (3.2%) patients, respectively. Eleven (17.7%) patients experienced postoperative complications and three died. The median follow-up was 27 months. The 1-, 3- and 5-year overall survival rates were 88.0%, 63.3% and 44.2%, respectively, with a corresponding disease-free survival rate of 68.1%, 54.8%, and 43.9%, respectively.The univariate analysis showed that pre-treatment stage â ¡, down-staging, T/N pCR, good tumor response to neoadjuvant chemoradiotherapy, pN0 and R0 resection were favorable prognostic factors (P<0.05). The multivariate analyses indicated that pre-treatment stage was an independent prognostic factor. CONCLUSIONS: For patients with thoracic ESCC, IMRT-based neoadjuvant chemoradiotherapy followed by surgery can achieve a higher R0 resection rate, down-staging rate, higher pCR rate, and a better tolerance. The incidence of postoperative complications is low. Pre-treatment stage, down-staging, pathological tumor response, lymph node status and R0 resection results are prognostic factors, and the pre-treatment stage is an independent prognostic factor.

OBJECTIVE: This study aimed to evaluate the impact of technical advancement of radiation therapy in patients with LA-NSCLC receiving definitive radiotherapy (RT). METHODS: Patients treated with definitive RT (≥50 Gy) between 2000 and 2010 were retrospectively reviewed. Overall survival (OS), cancer specific survival (CSS), locoregional progression-free survival (LRPFS), distant metastasis-free survival (DMFS) and progression-free survival (PFS) were calculated and compared among patients irradiated with different techniques. Radiation-induced lung injury (RILI) and esophageal injury (RIEI) were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events 3.0 (NCI-CTCAE 3.0). RESULTS: A total of 946 patients were eligible for analysis, including 288 treated with two-dimensional radiotherapy (2D-RT), 209 with three-dimensional conformal radiation therapy (3D-CRT) and 449 with intensity-modulated radiation therapy (IMRT) respectively. The median follow-up time for the whole population was 84.1 months. The median OS of 2D-RT, 3D-CRT and IMRT groups were 15.8, 19.7 and 23.3 months, respectively, with the corresponding 5-year survival rate of 8.7%, 13.0% and 18.8%, respectively (P<0.001). The univariate analysis demonstrated significantly inferior OS, LRPFS, DMFS and PFS of 2D-RT than those provided by 3D-CRT or IMRT. The univariate analysis also revealed that the IMRT group had significantly loger LRPFS and a trend toward better OS and DMFS compared with 3D-CRT. Multivariate analysis showed that TNM stage, RT technique and KPS were independent factors correlated with all survival indexes. Compared with 2D-RT, the utilization of IMRT was associated with significantly improved OS, LRPFS, DMFS as well as PFS. Compared with 3D-CRT, IMRT provided superior DMFS (P=0.035), a trend approaching significance with regard to LRPFS (P=0.073) but no statistically significant improvement on OS, CSS and PFS in multivariate analysis. The incidence rates of RILI were significantly decreased in the IMRT group (29.3% vs. 26.6% vs.14.0%, P<0.001) whereas that of RIET rates were similar (34.7% vs. 29.7% vs. 35.3%, P=0.342) among the three groups. CONCLUSIONS: Radiation therapy technique is a factor affecting prognosis of LA-NSCLC patients. Advanced radiation therapy technique is associated with improved tumor control and survival, and decreased radiation-induced lung toxicity.

The objective of this study was to evaluate the effects of different litter mixture compositions on bedding system temperature, pH and volatile fatty acid and ammonia-N (NH3-N) content, and the serum physico-chemical parameters and growth indices of calves. Thirty-two Limousin calves (280±20 kg) were randomly assigned to four groups (n = 8 for each group) according to the bedding system used: i) control with soil only (CTR); ii) mixture with 50% paddy hulls (PH), 30% saw dusts (SD), 10% peat moss (PM) and 10% corn cobs (CC) (TRT1); iii) mixture with 15% PH, 15% SD, 10% PM, 40% CC, and 20% corn stover (CS) (TRT2); iv) mixture with 30% PH, 10% PM, 40% CC, and 20% CS (TRT3). The litter material combinations of different treatments were based on the cost of bedding system materials in China. The cost of four treatments from low to high: Control
RESUMEN
The aim of this study was to investigate risk factors and surgical interventions associated with primary postpartum haemorrhage (PPH) unresponsive to first-line therapies. A retrospective analysis was performed of 212 women who experienced primary PPH (blood loss ≥ 500 ml). Logistic regression analysis identified that caesarean section (odds ratio [OR] 2.745; 95% confidence interval [CI], 1.063-7.085; p = 0.037) and abnormal placental adhesion (OR 3.823; 95% CI, 1.333-10.963; p = 0.013) were risk factors for PPH unresponsive to first-line therapies. There was no significant difference in blood loss, blood transfusion and success rate among intrauterine tamponade, B-Lynch suture and uterine artery ligation. Intrauterine tamponade is the least invasive and most rapid approach, so it should be taken as the first choice for surgical management after unresponsiveness to first-line therapies.

The zona pellucida 3 (ZP3) plays a crucial role in reproductive immunology. We obtained a full-length cDNA encoding Chinese Zokor zp3, using rapid amplification of cDNA ends-polymerase chain reaction (RACE-PCR). The cDNA contains an open reading frame of 1269 nucleotides encoding a polypeptide of 422 amino acid residues. The amino acid sequence has a high degree of homology with hamster (78%), mouse (76%), and rat (74%). XhoI and SacI sites restricted 1158 bp fragment of zokor ZP3 cDNA, excluding the signal sequence and transmembrane-like domain was cloned under the phage T7 promoterlac operator control in the pET-28a(+) vector. Recombinant pET-zokorZP3 (r-ZP3) was expressed as a poly-histidine fusion protein in E. coli strain BL21 (DE3).

Increasing cost and scarcity of maize has stimulated the use of alternative feed sources (AFS) in the diets of cattle. In this study, we investigated the effects of partial or total replacement of maize on nutrient digestibility, growth performance, blood metabolites, and economics in Limousin crossbred feedlot cattle. Forty-five Limousin×Luxi crossbred bulls were randomly assigned to the three treatment groups, orthodox diet (OD; 45.0% maize), partial replacement diet (PRD; 15% maize, 67% AFS), total replacement diet (TRD; 0% maize, 100% AFS). The growth feeding trial lasted for 98 days. Dry matter intake (DMI) and average daily gain (ADG) were recorded. The digestion trial was carried out after the end of the growth trial. Total faeces and feed samples were measured daily. Digestibilities of dry matter (DM) and organic matter (OM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were calculated. After the feeding trial, blood metabolites were measured in 12 animals from each group. Initial and final body weights did not differ significantly among treatment groups (p>0.05). The ADG and DMI were 1.72 and 8.66, 1.60 and 9.10, and 1.40 and 9.11 kg/d for OD, PRD, and TRD, respectively. The PRD and TRD exhibited lower ADG (p<0.01) and higher DMI (p<0.01) than OD. The DMI (%body weight) was comparable between groups (p>0.5). Feed efficiency of PRD and TRD were lower than OD (p<0.01). The DM digestibility decreased with reduced level of maize (p = 0.10), OM digestibility was higher in OD (p<0.05), and CP, NDF and ADF digestibilities were similar for all groups (p>0.05). Blood urea nitrogen (mg/dL) in PRD and TRD was higher than OD (p<0.01), while other blood parameters did not differ significantly. Feed costs ($/head/d) were 1.49, 0.98, and 0.72 for OD, PRD, and TRD, respectively (p<0.01). Feed costs per kg gain ($) were significantly lower for PRD (0.63) and TRD (0.54) than OD (0.89; p<0.01). Overall profit ($/head) and daily profit ($/head/d) did not differ significantly between treatments (p>0.05), although TRD showed the highest economic benefits overall (p<0.01). While a traditional diet maximized the growth rate, partial or total replacement of dietary maize with AFS proved economically feasible due to their lower costs and comparable nutrient digestibilities of DM, CP, NDF, and ADF. Partial replacement may prove economically competitive in the current situation of China.
RESUMEN
OBJECTIVES: We sought to evaluate whether clinical, lesion-related and procedural factors may predict in-stent restenosis (ISR) after intracranial stenting. METHODS: Sixty-one Chinese patients with 65 lesions treated with single bare metal balloon-mounted stent for symptomatic intracranial arterial stenosis underwent conventional angiographic follow-up after procedures between March 2004 and July 2009. Clinical, lesion-related and procedural factors were analysed for any predictive power for the ISR using univariate and multivariate analysis. ISR was defined as >50% stenosis within or at the edge of the stent or absolute luminal loss >20%. RESULTS: ISR was found in 18 patients (18/61, 29.5%) with 20 lesions (20/65, 30.8%) at a median follow-up of 7 months (range, 5-30 months). Univariate analysis revealed that diabetes, Mori classification, lesion length and stent diameter were associated with ISR. In addition, diabetes (hazard ratio (HR), 2.661; 95% confidence interval (CI), 1.044-6.787; P=0.040) and lesion length (HR, 1.206; 95% CI, 1.023-1.421; P=0.026) were detected as two independent predictors for ISR by stepwise multivariate Cox regression analysis. CONCLUSIONS: ISR after intracranial stenting with bare metal balloon-mounted stents in our series seems to be more frequent than those reported by the majority of the published case series. Diabetes and lesion length are associated with increased risk of ISR.

OBJECTIVE: To investigate the seroprevalence of Toxoplasma gondii infections among patients with rheumatoid arthritis, malignant tumors and schizophrenia in Wuxi City, so as to provide data support for the control of toxoplasmosis in these patients. METHODS: A total of 205 cases with definitive diagnosis of rheumatoid arthritis, 257 cases with definitive diagnosis of malignant tumors and 235 cases with definitive diagnosis of schizophrenia were recruited, while 250 healthy volunteers served as controls. The demographic features were captured from the study subjects and serum samples were collected. The serum IgG and IgM antibodies against T. gondii were detected using an enzyme-linked immunosorbent assay (ELISA) in all study subjects, and the positive rates of anti-T. gondii IgG and IgM antibodies were compared between the patients and controls. RESULTS: The seroprevalence of the anti-T. gondii IgG antibody was 20.98%, 24.12% and 24.68% in patients with rheumatoid arthritis, malignant tumors and schizophrenia, which were all significantly greater than in healthy controls (χ2 = 31.54, 42.12 and 42.98, all P values < 0.01), and the seroprevalence of the anti - T. gondii IgM antibody was 1.46%, 2.72% and 1.70% among patients with rheumatoid arthritis, malignant tumors and schizophrenia, which were all significantly higher than in healthy controls (χ2 = 0.06, 1.52 and 0.21, all P values > 0.05). CONCLUSIONS: The patients with rheumatoid arthritis, malignant tumors and schizophrenia present with higher seroprevalence of the anti-T. gondii IgG antibody than healthy controls in Wuxi regions. Screening of T. gondii infections among the patients with rheumatoid arthritis, malignant tumors and schizophrenia should be intensified to prevent the damages caused by T. gondii infections.

In the present study, calcium propionate (CaP) was used as feed additive in the diet of calves to investigate their effects on rumen fermentation and the development of rumen epithelium in calves. To elucidate the mechanism in which CaP improves development of calf rumen epithelium via stimulating the messenger RNA (mRNA) expression of G protein-coupled receptors, a total of 54 male Jersey calves (age=7±1 days, BW=23.1±1.2 kg) were randomly divided into three treatment groups: control without CaP supplementation (Con), 5% CaP supplementation (5% CaP) and 10% CaP supplementation (10% CaP). The experiment lasted 160 days and was divided into three feeding stages: Stage 1 (days 0 to 30), Stage 2 (days 31 to 90) and Stage 3 (days 91 to 160). Calcium propionate supplementation percentages were calculated on a dry matter basis. In total, six calves from each group were randomly selected and slaughtered on days 30, 90 and 160 at the conclusion of each experimental feeding stage. Rumen fermentation was improved with increasing concentration of CaP supplementation in calves through the first 30 days (Stage 1). No effects of CaP supplementation were observed on rumen fermentation in calves during Stage 2 (days 31 to 90). Supplementation with 5% CaP increased propionate concentration, but not acetate and butyrate in calves during Stage 3 (days 91 to 160). The rumen papillae length of calves in the 5% CaP supplementation group was greater than that of Con groups in calves after 160 days feeding. The mRNA expression of G protein-coupled receptor 41 (GPR41) and GPR43 supplemented with 5% CaP were greater than the control group and 10% CaP group in feeding 160 days calves. 5% CaP supplementation increased the mRNA expression of cyclin D1, whereas did not increase the mRNA expression of cyclin-dependent kinase 4 compared with the control group in feeding 160-day calves. These results indicate that propionate may act as a signaling molecule to improve rumen epithelium development through stimulating mRNA expression of GPR41 and GPR43.

Mesenchymal stem cells (MSCs) are pluripotent progenitors for a variety of cell types. Their down-regulation of the immune response in vivo has been hypothesized, but not yet substantiated, by experimental evidence. We investigated graft function, histology, animal survival days reverse transcriptase-polymerase chain reactor (RT-PCR) analysis of interleukin (IL)-1, tumor necrosis factor (TNF)-alpha, and transforming growth factor (TGF)-beta1. The results demonstrated that MSCs down-regulated immune responses, reduced production of some inflammatory mediators, preserved graft function in the initial stage after transplantation, and prolonged animal survival. However, the effects were not as strong as those of cyclosporine (CsA) therapy. Moreover, MSCs combined with low-dose CsA protected graft function, but could not prolong animal survival compared with CsA monotherapy, indicating a potential interaction between MSC and CsA activities, possibly allowing reduced CsA doses.
