RESUMO

The fruit of Ligustrum lucidum (FLL, Nuzhenzi in Chinese) is an important traditional medicine, and have attracted significant research attention because of their various biological activities. However, there are few research reports available on the use of FLL as a feed additive in livestock nutrition, particularly in layers. This study was conducted to determine the effects of supplementation of the diet of laying hens with FLL on laying performance, egg quality and blood metabolites. A total of 360 72-week-old hens were allocated to three dietary treatments (eight replications of 15 hens/treatment group) and were fed either a control diet or a diet supplemented with an inclusion level of 0.25% or 0.50% of FLL powder in the final feed, until 78 weeks of age. Hens were housed in a three-tier cage system. Feed and water were provided ad libitum. Blood samples and eggs were collected at the end of the experiment. The results showed that dietary supplementation with FLL did not affect egg weight, feed conversion ratio, eggshell thickness, albumen height, egg yolk color, eggshell breaking strength or egg shape index. However, FLL supplementation significantly decreased (P<0.001) mortality, cracked-egg rate and blood serum levels of cholesterol, low-density lipoprotein cholesterol, triglycerides and alanine aminotransferase, and increased (P<0.001) blood serum levels of high-density lipoprotein cholesterol. No differences in serum levels of total protein, albumin, glucose, calcium, aspartate aminotransferase or alkaline phosphatase were observed in hens fed FLL compared with the control group. It can be concluded that FLL, at a supplementation level of 0.25% final feed, can be used as an effective feed additive to improve the performance of laying hens during the late laying period.

RESUMO

We investigated the possible association between two single nucleotide polymorphisms of IL10 (-1082A/G and -592C/A) and susceptibility to ischemic stroke. In total, 335 patients with proven ischemic stroke and 335 control subjects were recruited from Xinxiang Central Hospital between March 2013 and May 2015. The IL10 -1082A/G and -529C/A polymorphisms were investigated by polymerase chain reaction-restriction fragment length polymorphism. When compared with the control subjects, patients with ischemic stroke were more likely to be male, have a habit of tobacco smoking, have higher BMI, have hypertension or diabetes mellitus, and have higher levels of TC, LDL-C, HDL-C, and TG. The multivariate logistic regression analyses revealed that the AA genotype of IL10 -1082A/G was significantly associated with development of ischemic stroke in a Chinese population compared with the GG genotype (OR = 1.93, 95%CI = 1.15-3.25). In the dominant model, the association between GA+AA genotype of IL10 -1082A/G and risk of ischemic stroke was also significant compared with the GG genotype, and the adjusted OR (95%CI) for the GA+AA genotype was 1.41 (1.02-1.94). Thus, our study suggests that IL10 gene polymorphisms contribute to the development of ischemic stroke.

RESUMO

The aim of the study was to evaluate the effect of Chinese herbal mixture (CHM) in laying hen diets on performance, egg quality and egg nutrition components, as well as selected blood biochemical parameters. A total of 270 Lohmann Brown laying hens, 24 week of age, were randomly distributed into three dietary treatments and fed for 6 week. The CHM was used at the levels of 0%, 0.5% and 1.0% in the diets of the control and two treatment groups respectively. Each dietary treatment was divided into five replicates, comprising of 18 hens each. Hens were housed in a 3-tier battery system. Feed and water were provided ad libitum. Blood samples and eggs were collected at the end of the experiment. The results showed that dietary treatments did not affect egg weight, mortality, eggshell thickness, albumen height, Haugh units, eggshell-breaking strength and egg-shape index. Dietary supplementation of CHM significantly improved (p < 0.05) laying rate and the lowest feed conversion ratio were observed with 1.0% CHM supplementation diets. CHM supplementation decreased (p < 0.05) cracked-egg rate, egg yolk cholesterol, blood serum levels of cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL-C) and alanine aminotransferase (ALT) and increased blood serum levels of high-density lipoprotein cholesterol (HDL-C). No differences in serum total protein, serum albumen, serum glucose and aspartate amino transferase (AST) were observed in hens fed CHM. In conclusion, dietary supplementation with CHM improved egg production and egg quality and reduced serum cholesterol concentrations in laying hens. Dietary supplementation of 1.0% CHM in layer diets may be a feasible means of producing eggs with lower cholesterol and higher egg yolk phospholipid contents for health conscious consumers.

RESUMO

The successful reduction of postoperative discomfort is of great significance. This review aims to evaluate the efficacy of low-level laser therapy (LLLT) for the reduction of complication caused by impacted mandibular third molars extraction. An extensive literature search up to October 2013 for randomized controlled trials (RCTs) was performed through CENTRAL, PubMed, Embase, Medline, and CNKI. Six RCTs in which involves 193 participants are included in the meta-analysis. Among them, three RCTs exhibit a moderate risk of bias, while the other three show a high bias risk. Compared with placebo laser/control group, pain is significantly reduced with LLLT on the first day (mean difference [MD] = -2.63, 95% confidence interval [CI] -4.46 to -0.79, P = 0.005). The superiority of LLLT in pain control persists on the second day (MD = -2.34, 95% CI -4.61 to -0.06, P = 0.04) and the third day (MD = -3.40, 95% CI -4.12 to -2.68, P < 0.00001). Moreover, LLLT reduces an average of 4.94 mm (MD = 4.94, 95 % CI 1.53 to 8.34, P = 0.004) of trismus compared with placebo laser irradiation in the first 3 days. On the seventh day, the superiority of LLLT also persists (MD = 3.24, 95% CI 0.37 to 6.12, P = 0.03). In the first 3 days after surgery, extraoral irradiation (MD = -0.69, 95% CI -1.30 to -0.08, P = 0.03) and intraoral combined with extraoral irradiation (MD = -0.65, 95% CI -1.15 to -0.15, P = 0.01) reduced facial swelling significantly. On the seventh day, the intraoral combined with extraoral irradiation group (MD = -0.32, 95% CI -0.59 to -0.06, P = 0.02) still showed benefit in relieving facial swelling. However, because of the heterogeneity of intervention and outcomes assessment and risk of bias of included trials, the efficacy is proved with limited evidence. In the future, well-designed RCTs with larger sample size will be required to provide clearer recommendations.

RESUMO

This review aimed to evaluate the efficacy of low-level laser therapy (LLLT) for accelerating tooth movement during orthodontic treatment. An extensive electronic search was conducted by two reviewers. Randomized controlled trials (RCTs) and quasi-RCTs concerning the efficacy of LLLT for accelerating tooth movement during orthodontic treatment were searched in CENTRAL, Medline, PubMed, Embase, China Biology Medicine Disc (CBM), China National Knowledge Infrastructure (CNKI), and Google Scholar. Six RCTs and three quasi-RCTs, involving 211 patients from six countries, were selected from 173 relevant studies. All nine articles were feasible for the systematic review and meta-analysis, five of which were assessed as moderate risk of bias, while the rest were assessed as high risk of bias. The mean difference and the 95 % confidence interval (95 % CI) of accumulative moved distance of teeth were observed among all the researches. The results showed that the LLLT could accelerate orthodontic tooth movement (OTM) in 7 days (mean difference 0.19, 95 % CI [0.02, 0.37], p = 0.03) and 2 months (mean difference 1.08, 95 % CI [0.16, 2.01], p = 0.02). Moreover, a relatively lower energy density (5 and 8 J/cm(2)) was seemingly more effective than 20 and 25 J/cm(2) and even higher ones.

RESUMO

Parenchyma vascular malformation (VM) is a common disease in modern society. Here, we investigated the clinical effects and safety of interventional therapy (IT) on the treatment of parenchyma VM. From January 1998 to December 2010, 31 patients with VM who elected IT were investigated, including 11 cases of venous VM and 20 cases of arteriovenous malformation. There were 19 males and 12 females, ranging from 12 to 51 years in age. VM often occurred in the four limbs and other areas, such as the trunk and reproductive organs. Under the guidance of digital subtraction angiography, vascular hardener was injected into the VM spot via percutaneous puncture. Then, embolotherapy was conducted via the transcatheter feeding artery. We found that, in all cases, the malformed vessels were completely or partially blocked. After treatment, the local swelling of vessels was alleviated and the diabrosis and bleeding ceased. The soft tissue lump shrank, then stiffened and became fixed. There was no occurrence of severe intraoperative or postoperative complications in any patient. In summary, IT is an effective method for treating parenchyma VM, causes only a minor operative wound, and should be viewed as the first choice intervention.

RESUMO

AIM: Centromere protein H (CENP-H) is one of the essential components of the human active kinetochore which close links with carcinogenesis. Its expression and clinical value of prognostic prediction for gastric cancer (GC) is unclear. METHODS: CENP-H and Ki-67 expressions in specimens from 166 patients with GC were determined by tissue microarrays and immunostaining. Their correlations between patients' clinicopathologic features and prognosis were explored. For mechanisms, quantitative CENP-H examination on gastric cancer tissue and cell lines was performed via real-time quantitative PCR and Western Blot. Its effect on Survivin expression and cell function was evaluated via CENP-H knocking down (SiRNA) or overexpression. RESULTS: Highly expression of CENP-H was found in 85 of 166 GC, showing a significant correlation with tumour size, depth of infiltration, lymph node metastasis, distant metastasis and UICC staging of gastric carcinoma (P < 0.05), as well as clinical prognosis (coefficient = 0.550, P < 0.001). Multivariate analysis revealed that combined CENP-H and Ki67 expression was a more valuable independent prognostic predictor for patients' survival (hazard ratio, 2.18; P = 0.0109). Furthermore, total mRNA and protein expression of CENP-H in GC tissue and cell lines were noticeably increased. Survivin expression and cell function including growth, proliferation and clonogenic ability could be inhibited by CENP-H siRNA or enhanced by overexpressing CENP-H. CONCLUSION: High expression of CENP-H in GC indicates poor prognosis and Survivin may mediate its procancer role. Combined evaluation of CENP-H and Ki-67 aids in predicting the clinical prognosis.

RESUMO

This review aimed to identify the efficacy of low-level laser therapy (LLLT) in the management of orthodontic pain. This systematic review and meta-analysis was carried out in accordance with Cochrane Handbook and the PRISMA statement. An extensive literature search for RCTs, quasi-RCTs, and CCTs was performed through CENTRAL, PubMed, Embase, Medline, CNKI, and CBM up to October 2011. Risk of bias assessment was performed via referring to the Cochrane tool for risk of bias assessment. Meta-analysis was implemented using Review Manager 5.1. As a result, four RCTs, two quasi-RCTs, and two CCTs were selected from 152 relevant studies, including 641 patients from six countries. The meta-analysis demonstrated that 24% risk of incidence of pain was reduced by LLLT (RR = 0.76, 95% CI range 0.63-0.92, P = 0.006). In addition, compared to the control group, LLLT brought forward "the most painful day" (MD = -0.42, 95% CI range -0.74- -0.10, P = 0.009). Furthermore, the LLLT group also implied a trend of earlier end of pain compared with the control group (MD = -1.37, 95% CI range -3.37-0.64, P = 0.18) and the pseudo-laser group (MD = -1.04, 95% CI range -4.22-2.15, P = 0.52). However, because of the methodological shortcomings and risk of bias of included trials, LLLT was proved with limited evidence in delaying pain onset and reducing pain intensity. In the future, larger and better-designed RCTs will be required to provide clearer recommendations.

RESUMO

The mechanisms of iron-mediated inhibition of the H(+)-ATPase activity of plasma membrane (PM) vesicles isolated from wheat roots were investigated. Both FeSO(4) and FeCl(3) significantly inhibited PM H(+)-ATPase activity, and the inhibition could be reversed by the addition of the metal ion chelator EDTA-Na(2) or a specific Fe(2+) chelator, indicating that the inhibitory effect was due to specific action of Fe(2+) or Fe(3+). Measurement of the extent of lipid peroxidation showed that oxidative damage on the PM caused by Fe(2+) or Fe(3+) seemed to be correlated with the inhibition of PM H(+)-ATPase activity. However, prevention of lipid peroxidation with butylated hydroxytoluene did not affect iron-mediated inhibition in the PM H(+)-ATPase, suggesting that the inhibition of the PM H(+)-ATPase was not a consequence of lipid peroxidation caused by iron. Investigation of the effects of various reactive oxygen species scavengers on the iron-mediated inhibition of H(+)-ATPase activity indicated that hydroxyl radicals (*OH) and hydrogen peroxide (H(2)O(2)) might be involved in the Fe(2+)-mediated decrease in PM H(+)-ATPase activity. Moreover, iron caused a decrease in plasma protein thiol (P-SH), and Fe(3+) brought a higher degree of oxidation in thiol groups than Fe(2+) at the same concentration. Modification of the thiol redox state in the PM suggested that reducing thiol groups were essential to maintain PM H(+)-ATPase activity. Incubation of the specific thiol modification reagent 5,5-dithio-bis(2-nitrobenzoic acid) with the rightside-out and inside-out PM revealed that thiol oxidation occurred at the apoplast side of the PM. Western blotting analysis revealed a decrease in H(+)-ATPase content caused by iron. Taken together, these results suggested that thiol oxidation might account for the inhibition of PM H(+)-ATPase caused by iron, and that *OH and H(2)O(2) were also involved in Fe(2+)-mediated inhibition.

RESUMO

The relation between blood pressure and urinary electrolytes, including sodium, potassium, calcium, and magnesium were examined in male farmers of the Yi nationality who live in three separate communities in Sichuan and Yunnan provinces in China, where the lifestyles, habits, and living conditions are very different. One of these three communities was unacculturated and had the lowest average blood pressure as well as the lowest prevalence rate of hypertension in China; one was acculturated and had the highest average blood pressure; and the third was moderately acculturated with its average blood pressure between the other two. Blood pressure was taken on each of 3 days and corresponding 24-hour urine specimens were collected to measure potassium, sodium, calcium, magnesium, urea nitrogen, and creatinine. Ecological and individual-based data correlation analyses were employed to study the relations among age, body mass index, some related indexes of electrolyte derivatives, and blood pressure. Multiple regression analyses were used to explore the relation of blood pressure to the above indexes, adjusted for age, body mass index, urea nitrogen and creatinine, and geographical differences. Statistically significant correlation analyses showed that systolic blood pressure was positively associated with sodium-creatinine, calcium-creatinine, sodium-potassium, calcium-magnesium, and urea nitrogen and creatinine ratios; negatively associated with potassium-creatinine and magnesium-creatinine ratios. The ridge regression analysis selected only calcium-magnesium ratio as a predictor of systolic blood pressure.
