Inhibitory effect of ranibizumab on retinal oxidative stress in a rat model of choroidal neovascularization and its mechanism / 中华实验眼科杂志

Objective:To study the effect of ranibizumab on retinal oxidative stress in a rat model of choroidal neovascularization (CNV) and its mechanism.Methods:Sixty SPF male SD rats aged 10 weeks were randomly divided into normal control group, model control group, ranibizumab group, nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor (ML385) group, ranibizumab+ ML385 group, with 12 rats in each group according to a random number table.Except for the normal control group, the CNV model was established in the other four groups via krypton laser induction.According to grouping, the ranibizumab group, ML385 group and ranibizumab+ ML385 group were intravitreally injected with 1 μl of ranibizumab, ML385 and ranibizumab+ ML385, respectively.Model control group and normal control group received an intravitreal injection of normal saline of equal volume.The CNV area was measured through choroidal wholemounts.Pathological change of the retina was observed by hematoxylin and eosin staining.Expressions of Nrf2, superoxide dismutase (SOD) and quinone oxidoreductase 1 (NQO1) were detected using Western blot and real-time PCR.The use and care of animals complied with laboratory animal welfare guidelines.The study protocol was approved by the Laboratory Animal Welfare and Ethics Committee of Tengzhou Central People's Hospital (No.JN.No20210214S1200430[121]).Results:CNV areas of the model control group, ML385 group and ranibizumab+ ML385 group were (23.01±1.52)×10 3, (30.23±2.01)×10 3 and (18.56±1.85)×10 3 μm 2, respectively, which were significantly higher than (12.35±1.22)×10 3 μm 2 of ranibizumab group (all at P<0.001). The CNV area of ranibizumab+ ML385 group was smaller than that of model control group and ML385 group, and the CNV area of ML385 group was larger than that of model control group, showing statistically significant differences (all at P<0.001). Hematoxylin and eosin staining showed that the structural damage of the retinal pigment epithelium-choroid-sclera complex was slighter in ranibizumab group than model control group, severer in ranibizumab+ ML385 group than ranibizumab group but slighter than model control group, severer in ML385 group than model control group.The mRNA and protein expressions of Nrf2, SOD and NQO1 of ranibizumab group were lower than those of normal control group but higher than those of model control group, ML385 group and ranibizumab+ ML385 group, and the differences were statistically significant (all at P<0.05). The mRNA and protein expressions of Nrf2, SOD and NQO1 were higher in ranibizumab+ ML385 group than model control group and ML385 group, showing statistically significant differences (all at P<0.05). Conclusions:Ranibizumab can inhibit the growth of CNV induced by krypton laser and reduce RPE damage caused by retinal oxidative stress.The mechanism is related to the activation of Nrf2/ARE pathway.

Objective:To investigate the characteristics of congenital hypothyroidism (CH) in premature infants and analyze the predictors of transient congenital hypothyroidism(TCH) and permanent CH (PCH).Methods:A retrospective study was conducted on the preterm infants with CH born in Beijing from January 2008 to June 2018. They were screened, diagnosed and treated by the Beijing Neonatal Disease Screening Center. They were assigned into TCH and PCH groups according to the clinical prognosis. Univariate analysis and Logistic regression analyses were used to determine the predictors of PCH, and the receiver operating characteristic curve (ROC) was drawn to determine the best cut-off point.Results:A total of 2 216 892 newborns were screened, 15 382 were initially screened positive, the median time of screening was 4(4,10) d after birth, and the median time of postnatal reexamination was 30(22,42) d after birth, 14 576 newborns were reexamined, the reexamination rate was 94.8%. A total of 92 preterm infants were diagnosed with CH, of which 60 were TCH, accounting for 65.2%; 28 were PCH, accounting for 30.4%; and 4 were lost to follow-up, accounting for 4.3%. Univariate analysis showed that in the PCH group, the abnormal rate of thyroid B-ultrasound, levothyroxine (LT4) dose at 1-year old, thyrotropin (TSH) level at 2 years old, LT4 dose at 2 years old, LT4 dose and free thyroxine (FT4) level at 3 years old were higher than those in the TCH group. Logistic regression analysis revealed that abnormal B-ultrasound ( OR=12.184,95% CI 2.270~65.403), and elevated TSH level at 2 years old ( OR=2.033,95% CI 1.280~3.228),increased LT4 dose at 3 year old ( OR=21.435,95% CI 3.439~133.584) are the risk factors for PCH. The maximum area under ROC curve was 0.798 at 3 years old (95% CI 0.680~0.916), the best cut-off point was 1.3 μg/(kg·d) for the 3-year-old drug dose; followed by 2-year-old TSH level, which was 0.683 (95% CI 0.548~0.817), the best cut-off point was 4.51 μIU/ml. Conclusions:TCH accounted for a large proportion of preterm infants with CH. During the follow-up, the increased LT4 dose at 3 years old and the elevated TSH level at 2 years old were the early predictors of PCH.

The effects of functional electric stimulation and upper limb cycle training on upper limb motor function and daily living activities post-stroke / 中华物理医学与康复杂志

Objective:To explore the effect of combining functional electric stimulation (FES) with upper limb cycle training in rehabilitating upper limb motor function and ability in the activities of daily living after a stroke.Methods:Sixty hemiplegic stroke survivors were randomly divided into an experimental group and a control group. In addition to conventional rehabilitation therapy, the experimental group underwent 20 minutes of MOTOmed upper limb cycle training every day while receiving FES. The control group received only the 20 minutes of cycle training. Before and after 4 weeks, Brunnstrom staging was used to quantify hand and upper extremity functioning. The Fulg-Meyer assessment upper extremity scale (FMA-UE) and the modified Barthel index (MBI) were also used before the training and after 1, 2, 3 and 4 weeks of the treatments.Results:After 4 weeks of treatment, significant differences were observed in the average BS scores of both groups compared with before the intervention. The average hand and upper limb stages of the experimental group were significantly better than the control group′s averages. Significant improvement was also observed in the average FMA-UE and MBI scores of both groups after only one week, with significantly greater improvement in the experimental group.Conclusions:Supplementing upper limb cycle training with FES can significantly improve the upper limb motor function and ability in the activities of daily living of stroke survivors. It is more effective than the MOTOmed exercise alone.

Identification of potential splicing variants in two Chinese patients with osteogenesis imperfecta / 中华骨科杂志

Objective:To identify pathogenicity of the potential splicing variants in two Chinese Han patients with osteogenesis imperfecta.Methods:Genomic DNA was extracted using the conventional phenol-chloroform method; whole exome sequencing (WES) was used to analysis the disease-related variants in the two probands; Minigene assay was used to identify pathogenicity of the variants found in the patients' genome that possibly affect RNA splicing.Results:Two potential splicing variants, c.858+1_858+5delGTAAG in intron 12 of COL1A1 and c.1405-7C>T in intron 24 of COL1A2, were found in proband 1 and proband 2, respectively. In addition, a missense mutation, c.2972G>T (p.G991V) in exon 45 of COL1A2, was detected in proband 2. Minigene assay revealed that the variant in proband 1 caused the skipping of exon 12, while the variant in proband 2 did not lead to aberrant splicing. G199 of the COL1A2 in proband 2 was a highly conserved amino acid site, and the results suggested that c.2972G>T (p.G991V) may be the real pathogenic variant by the means of bioinformatics analysis.Conclusion:The variant c.858+1_858+5delGTAAG in COL1A1 was a causative variant that led to OI in proband 1, while the missense variant c.2972G>T (p.G991V) in COL1A2 was the cause of OI in proband 2, instead of the variant c.1405-7C>T. Minigene assay for potential splicing variants detected by WES could not only validate the pathogenicity of the candidate variants and enrich the mutation spectrum of OI, but also lay the foundation for patients' prenatal diagnosis and subsequent mechanism research.

MiRNA-148b targeted AMPKα1 mediates high glucose-induced apoptosis in human renal tubular epithelial cells via oxidative stress / 中华肾脏病杂志

Objective To investigate the expression and mechanism of microRNA-148b (miRNA-148b) in high glucose-induced renal tubular injury.Method HK-2 cells cultured in vitro were divided into normal glucose group,mannitol hypertonic control group and high glucose group.After 48 hours of culture,the expression of miRNA-148b was detected by real-time quantitative PCR.2',7'-Dichlorodihydrofluorescein diacetate (DCFH-DA) was used for detecting production of ROS and observed under fluorescence microscope for analysis;The expression of AMPKot1,Bcl-2,NOX2,NOX4,activated caspase3 (cleaved-caspase3) were detected by Western blotting.Results Compared with the normal glucose group,the expression of miRNA-148b was up-regulated in HK-2 cells in high glucose group and hypertonic group (P ＜ 0.01),and the production of ROS increased (P ＜ 0.01).The expression of NOX2 and NOX4 was increased,AMPKα1 and Bcl-2 decreased,and cleaved caspase-3 was increased (all P ＜ 0.01).Conclusions HG up-regulated miRNA-148b expression and down-regulated its target gene AMPKα1 which promotes the expression of NOX2 and NOX4 in HK-2 cells.MiRNA-148b promotes apoptosis of HK-2 cells via increasing production of ROS and enhancing cleaved-caspase3 for Bcl-2 insufficiency.The tubular toxicity of high glucose is partly due to osmotic pressure.MiRNA-148b may be involved in the pathological injury of diabetic nephropathy and is expected to become a new therapeutic target for diabetic nephropathy.

Progress on the risk factors of intracranial aneurysm rupture / 中国综合临床

Intracranial aneurysm ( IA) is one of the most common cerebrovascular diseases in our lves, characterized by high morbidity, high disability rate and high fatality rate. With the extensive application and improvement of imaging techniques, more and more unruptured intracranial aneurysms can be diagnosed and treated before rupture,which reduces the incidence of subarachnoid hemorrhage caused by its rupture. However, the optimal treatment for unruptured aneurysms remains controversial,and the risk of preventive intervention must be weighed against the unknown risk of individual aneurysm rupture. Therefore,it is necessary to predict the risk of rupture before treatment for unruptured aneurysms. In this paper, the high risk factors of IA rupture were discussed through literature research and a large number of clinical data analysis,which provided the basis for the treatment of intracranial aneurysms.

Meta-analysis of javanica oil emulsion injection combined with radiotherapy in the treatment of esophageal carcinoma / 实用医学杂志

Objective To evaluate the advantage and clinical value of javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma. Method Randomized controlled trials (RCTs) concerning javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma were made on electronic databases of CBM, CNKI, Wangfang, VIP and PubMed from 1990 to February 28, 2015. Quality of the included RCTs was assessed by Jadad scoring , and Meta-analyses were performed by RevMan5.3 software. Results Seven RCTs involving 575 patients were included in Meta-analysis. All studies were in low quality. The results of Meta-analyses showed that Javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma, compared with control groups, could increase the recent curative effect (P < 0.000 01) and improve the quality of live (P = 0.000 8), decrease the hematologic toxicities (P = 0.03) and the incidence rate of radioaction esophagitis (P = 0.02), but not enough evidence was found to prove that it can enhance survival rate (P = 0.25). Conclusions The results of Meta-analysis indicate that javanica oil emulsion injection may have therapeutic effects on the treatment of esophageal carcinoma. Yet the effects of javanica oil emulsion injection still need to be confirmed by large multi-center randomized controlled trials.

This study examined the potential antilithic effects of a traditional Chinese medicine Urtica dentata Hand (UDH) in experimental rats and screened the optimal extract of UDH as a possible therapeutic agent for kidney stones. The rat model of urinary calcium oxalate stones was induced by intragastric (i.g.) administration of 2 mL of 1.25% ethylene glycol (EG) and 1% ammonium chloride (AC) for 28 days and was confirmed by Color Doppler ultrasound imaging. The rats in different experimental groups were then intragastrically given petroleum ether extract (PEE), N-butanol extract (NBE), aqueous extract (AqE) of UDH, Jieshitong (positive control drug), and saline, respectively. Treatment with NBE significantly reduced the elevated levels of urinary calcium, uric acid, phosphate, as well as increased urinary output. Accordingly, the increased calcium, oxalate levels and the number of calcium oxalate crystals deposits were remarkably reverted in the renal tissue of NBE-treated rats. In addition, NBE also prevented the impairment of renal function to decrease the contents of blood urea nitrogen (BUN) and creatinine. Taken together, these data suggest that NBE of UDH has a beneficial effect on calcium oxalate urinary stones in rats by flushing the stones out and protecting renal function.
