ABSTRACT
The complement system is a protein response system with a precise regulatory mechanism, which has the functions of mediating inflammation, regulating immune response, dissolving cells and clearing immune complexes. Diabetic retinopathy(DR)is a common and severe ocular complication of diabetes and one of the common irreversible blinding eye diseases in ophthalmology, and its pathogenesis is complex, including hypoxia, oxidative stress, inflammation and abnormal polyol metabolism pathway. In recent years, there has been more and more evidence that dysregulation and inflammation of immune system are important factors in the pathogenesis of DR, and a variety of complement proteins play an important role in key processes such as inflammation regulation and angiogenesis. Therefore, the central purpose of this review is to discuss the role of the complement system and related regulatory proteins in DR, with the aim of elucidating the close relationship between the complement proteins and the occurrence and development of DR, and providing important references and new ideas for the prevention and treatment of DR. At the same time, the clinical research of complement system-targeted drugs is further elaborated.
ABSTRACT
Rapid serial visual presentation (RSVP) is a type of psychological visual stimulation experimental paradigm that requires participants to identify target stimuli presented continuously in a stream of stimuli composed of numbers, letters, words, images, and so on at the same spatial location, allowing them to discern a large amount of information in a short period of time. The RSVP-based brain-computer interface (BCI) can not only be widely used in scenarios such as assistive interaction and information reading, but also has the advantages of stability and high efficiency, which has become one of the common techniques for human-machine intelligence fusion. In recent years, brain-controlled spellers, image recognition and mind games are the most popular fields of RSVP-BCI research. Therefore, aiming to provide reference and new ideas for RSVP-BCI related research, this paper reviewed the paradigm design and system performance optimization of RSVP-BCI in these three fields. It also looks ahead to its potential applications in cutting-edge fields such as entertainment, clinical medicine, and special military operations.

Objective:To compare the clinical efficiency and safety between intravitreal injection of conbercept with and without macular photocoagulation for diabetic macular edema (DME).Methods:A non-random controlled study was conducted.Sixty patients (60 eyes) with DME treated in Shenzhen People's Hospital from January 2017 to January 2020 were enrolled.The patients receiving intravitreal injection of conbercept alone were divided into conbercept injection group (33 cases, 33 eyes), and those who underwent macular photocoagulation combined with intravitreal injection of conbercept were divided into combined treatment group (27 cases, 27 eyes). Best corrected visual acuity (BCVA) was examined using Early Treatment of Diabetic Retinopathy Study.The BCVA, central macular thickness (CMT) and fluorescein fundus angiography (FFA) examination were performed to observe the changes of macular edema and leakage area before and at 1, 3, 6, 9 and 12 months after treatment.The injection frequency, ocular and systemic complications were recorded.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Shenzhen Pepole's Hospital (No.LL-YK-20170405). Written informed consent was obtained from each patient prior to any medical examination.Results:There were better mean BCVA and lower CMT at 1, 3, 6, 9 and 12 months after treatment compared with the BCVA and CMT before treatment in the two groups (all at P<0.05). At 12 months after treatment, FFA showed that the improvement rate of macular edema was 91.0% (30/33) in the conbercept injection group and 96.3% (26/27) in the combined treatment group, showing a statistically significant difference between them ( χ2=3.430, P<0.05). The injection frequency was (4.36±1.62) times in the conbercept injection group, which was significantly higher than (3.41±0.64) times in the combined treatment group ( t=9.211, P<0.05). No ocular adverse events, including ocular hypertension, endophthalmitis and retinal pigment epithelial tears or systemic complications were found during the follow-up. Conclusions:Intravitreal injection of conbercept with or without macular photocoagulation can both maintain or improve visual acuity and alleviate exudative macular edema.They both show good safety, and the combined therapy has better long-term efficacy than conbercept alone.
ABSTRACT
Objective:To detect the changes of serum complement factors C3 and C4 in diabetic retinopathy (DR) patients, and to explore their role in the occurrence and development of DR.Methods:A cases-controlled study was carried out.Total of 195 patients with DR diagnosed in the First Affiliated Hospital of Harbin Medical University from December 2017 to December 2018 were selected as the DR group, 150 patients with type 2 diabetes were included as the diabetes group, and 281 simple age-related cataract or strabismus patients were collected at the same time and served as control group.Fasting venous blood was collected and serum was isolated.The concentration of C3 and C4 in serum was determined by immunoturbidimetry.The contents of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined by rate method, and the contents of total cholesterol and triglyceride were determined by enzyme method.Pearson linear correlation analysis was used to evaluate the correlation between serum complement factors and clinical parameters.Stepwise regression analysis was used to evaluate the influencing factors of complement factor C3 and C4 expression.This study adhered to the tenets of the Declaration of Helsinki and was approved by the Ethical Committee Review Board of the First Affiliated Hospital of Harbin Medical University(No.2016-81500711).Results:The concentration of serum complement factor C3 in the diabetes group was (1 154.0±177.4)mg/L, which was significantly higher than (1 077.3±177.0)mg/L in the DR group and (1 072.0±184.3)mg/L in the control group, the differences were statistically significant (all at P<0.05); The concentration of serum complement factor C4 in the DR group was (287.5±83.5)mg/L, which was significantly higher than (257.5±70.1)mg/L in the diabetes group and (263.7±77.2)mg/L in the control group, the differences were statistically significant (all at P<0.05). The correlation analysis results showed that the expression level of complement factor C3 was weakly positively correlated with total cholesterol and triglyceride in the diabetes and DR groups (diabetes group: r=0.250, P<0.05; r=0.205, P<0.05.DR group: r=0.308, P<0.01; r=0.213, P<0.01); The expression level of complement factor C4 was weakly positively correlated with total cholesterol and triglyceride in the DR group ( r=0.235, P=0.002; r=0.247, P=0.001). Multiple regression analysis showed that total cholesterol and triglyceride were the influencing factors of serum C3 and C4 expression in the DR group. Conclusions:Complement factors may participate in the pathological process of DR and serum complement factors C3 and C4 are affected by serum total cholesterol and triglyceride in DR patients.
ABSTRACT
OBJECTIVE:To study the effects of combined decoctions of alismatis rhizoma and curcumae radix and rehmanniae radix praeparata on the decoction amount of acteoside in rehmanniae radix praeparata,and provide reference for studying the effec-tive ingredients of three-drug effect. METHODS:Single decoction-1(rehmanniae radix praeparata 20 g),single decoction-2(alis-matis rhizoma 20 g),single decoction-3(curcumae radix 20 g),combined decoction-1(rehmanniae radix praeparata 20 g,alisma-tis rhizoma 20 g),combined decoction-2(rehmanniae radix praeparata 20 g,curcumae radix 20 g),combined decoction-3(alisma-tis rhizoma 20 g,curcumae radix 20 g)and combined decoction-4(rehmanniae radix praeparata 20 g,alismatis rhizoma 20 g,cur-cumae radix 20 g)were respectively taken to prepare dry extracts after extracting by refluxing,HPLC was used to detect the acteo-side content and calculate its decoction amount in sample. RESULTS:The decoction amounts of acteoside in single decoction-1, combined decoction-1,combined decoction-2 and combined decoction-4 dry extracts were 0.0354,0.0223,0.0228,0.0110 mg/g,respectively. Compared with single decoction-1 group,the last 3 groups had statistical significances(P<0.01);combined decoc-tion-4 showed lowest decoction amount in three-drug combined decoction group. Acteoside was not detected in the negative control groups(single decoction-2,single decoction-3 and combined decoction-3). CONCLUSIONS:The decoction amount of acteoside is reduced when alismatis rhizoma,curcumae radix and rehmanniae radix praeparata were decocted together,indicating that it may not be the main ingredient of playing effects in three-drug combined decoction liquid.

OBJECTIVE:To investigate the decoction amount changes of verbascoside,gallic acid in single decoction and com-bined decoction of rehmanniae radix preparata,corni fructus and poria,and provide scientific basis for further study of effective substance basis. METHODS:The single decoction,combined decoction with each 2 medicine and combined decoction with the 3 medicines of rehmanniae radix preparata,corni fructus and poria,were respectively prepared. HPLC was adopted to detect and com-pare the decoction amount of active component verbascoside in rehmanniae radix preparata and active component gallic acid in cor-ni fructus in each group. RESULTS:Compared with single decoction of rehmanniae radix preparata,the decoction amount of ver-bascoside was decreased in combined decoction of poria+rehmanniae radix preparata(P<0.01),decoction amount of verbascoside was increased in combined decoction of corni fructus+rehmanniae radix preparata or combined decoction with the 3 medicines(P<0.01). Compared with single decoction of corni fructus,the decoction amount of gallic acid in each combined decoction was de-creased (P<0.01). CONCLUSIONS:The combined decoction of rehmanniae radix preparata,corni fructus and poria has certain promotion and inhibition effects on the decoction of verbascoside in rehmanniae radix preparata and inhibition effect on the decoc-tion of gallic acid in corni fructus. It is speculated verbascoside may be one of the main components in combined decoction playing the role of effectiveness.
ABSTRACT
Objective To observe the clinical features, phenotypes and genotypes in a Chinese family with choroideremia (CHM). Methods A Chinese four-generation family (15 members) with CHM, including 5 patients (4 males/1 female), 2 female carriers and 8 healthy members, was enrolled in this study. Initially all family members underwent best corrected visual acuity (BCVA), indirect ophthalmoscopy, fundus fluorescein angiography, optical coherence tomography (OCT), visual field and full view electroretinogram (ERG). BCVA was followed up for 3 years. Venous blood samples were collected, and all of the 15 coding exons and flanking intron regions were amplified in the proband by polymerase chain reaction followed by direct sequencing. Protein structure was modeled based on the protein data bank and mutations in DeepView v4.0.1 to predict the effect of the mutations. A total of 180 healthy volunteers were enrolled as control group to matching CHM gene sequences. Results The visual acuity (VA) of 3/4 adult male patients began to decrease at less than 10, 10 and 30 years old, the average BCVA was 0.43. There were characteristic signs and symptoms of CHM including narrow visual field, extinguished rod and cone response in ERG, disappeared junction line and intermediate line of photoreceptor inner segment/outer segment on OCT. After 3 years, the mean BCVA decreased to 0.11. The BCVA of one young male patient was 1.0 in both eyes with minor changes fundus and visual field. The VA of the female patient began to decrease at 50 years old, her BCVA of two eyes were 0.5 and 0.25, respectively. The fundus changes were typical of CHM, with relative scotomas in the peripheral visual field of OD, and big scotomas in the OS. After 3 years, her mean BCVA decreased to 0.2. Of 2 female carriers, one had minor fundus changes (patches of pigmentary deposits, atrophy spots of retinal pigment epithelium cells), and the other was normal. A novel heterozygous c.1837G>A mutation in exon 15 of CHM was detected in the proband, which resulted in the substitution of serine by proline at codon 613 (p.D613N). Based on molecular modeling, the misfolded protein caused by the mutation might destabilize the structure of the helix that potentially could affect the global stability of the Rep-1 protein. Conclusions A novel c.1837G>A (p.D613N) mutation may be the causative mutation for CHM in this family. Female CHM carriers may have some signs and symptoms.
ABSTRACT
Objective To compare the bispectral index score ( BIS) correlationbetween standard frontal sensor position and an alternative zygomatic position under general anesthesia with propofol combined with remifentanil during neurosurgery. Methods Twenty patients undergoing neurosurgery were enrolled. Everyone received total intravenous anesthesia by target-controlled infusion of propofol and remifentanil. Two BISTM Quatro sensors mounted on the frontal and zygomatic regions were connected to BIS VistaTM monitors on each patient during general anesthesia.Data from each position were collected and analyzed at the time of awakening ( t1 ) , intubation ( t2 ) , incision ( t3 ) , the end of surgery ( t4 ) , and extubation ( t5 ) . Results At t1 , zygomatic BIS(88.95±6.42) was significantly lower than frontal BIS (84.85±9.64,P0.05). Scatter plot analysis revealed a significant correlation between BIS of frontal positionand that of zygomatic position( R2=0.892,P=0.000) . Conclusion During the anesthesia maintenance period,the zygomatic position can be availably used as an alternative position for monitoring if the operative field renders the standard frontal position unavailable.
ABSTRACT
Objective:To prepare a virus-like particle (VLP),containing Hepatitis B virus core antigen (HBcAg) and N-terminal peptides of the L2 protein of human papilloma virus (HPV),and investigate the immunogenicity of the VLP in mice and the protection against different strains of HPV .Methods:A fusion gene was synthesized to insert a DNA fragment ,coding for the N-terminal epitopes of the L2 protein of HPV16,into the HBcAg coding sequence;HBc-L2 fusion protein was highly expressed in E.coli using the pET9a and BL21(DE3) expression system;the purified fusion protein was used to immunize BALB/c mice and antibody titers against the L2 epitopes in mouse sera were determined by indirect ELISA;the levels of neutralizing antibodies against both HPV 16 and 18 were also analyzed.Results:HBc-L2 fusion protein was expressed in E.coli and purified,with the purity >80%,by ammonium sulfate pre-cipitation and CL-4B gel filtration;analysis of the purified fusion protein ,using size exclusion chromatography with multi-angle laser light scattering detection ( SEC-MALS) and electron microscope ,revealed that HBc-L2 was assembled into a stable VLP structure auto-matically following its expression;immunization of BALB/c mice with the purified VLPs resulted in high antibody titers in mouse sera against the L2 epitopes;furthermore,it was demonstrated that the sera from the immunized mice had neutralization activities against both HPV16 and HPV18.Conclusion:The immunogenicity of the L2 epitopes was highly enhanced by the construction of HBc-L2 fusion protein and the formation of the VLP structure;the fusion protein was also capable of inducing protections against different serotypes of HPV,therefore,it could be a potential HPV vaccine with a broad coverage and low production cost .
ABSTRACT
Objective To compare the outcome of double Endobutton plate versus clavicular hook plate (CHP) in treatment of Tossy grade Ⅲ acromioclavicular dislocation.Methods A cohort of 82 patients with Tossy grade Ⅲ acromiocavicular dislocation treated between January 2010 and August 2012 were reviewed retrospectively.Based on the treatment choices,the patients were divided into double Endobutton group (36 cases) and CHP group (46 cases).Operative situation,in-hospital parameters,and postoperative visual analogue scale (VAS) of the shoulder,shoulder abduction-rise or anteflexionrise,Constant-Murley shoulder score as well as complications were evaluated.Results There were no statistical differences between the two groups in aspects of operation time,intraoperative blood loss,and length of stay.Mean time to return to work was (13.1 ± 1.4) weeks in double Endobutton group,shorter than (15.5 ±2.6) weeks in CHP group (P ＜0.01).No statistical difference was observed for postoperative complications between the two groups.At postoperative 12 months,VAS was lower in double Endobutton group [(2.1 ± 0.7) points] vs CHP group [(2.9 ± 0.8) points,P ＜ 0.05],but abductionrise and anteflexion-rise were higher in double Endobutton group [(138.6 ± 15.7) °,(140.3 ± 17.6) °] vs CHP group [(91.7 ±8.4)°,(96.7 ± 10.5)°,P＜0.05].Conclusion To treat Tossy grade Ⅲ acromioclavicular dislocation,double Endobutton plate is associated with less shoulder pain,quicker recovery,better shoulder function restoration compared with CHP and there is no need for a second surgery to remove it.
ABSTRACT
ObjectiveTo investigate the effect of puerarin on the expression of pigment epithelium-derived factor (PEDF) in the retina of diabetic rats.MethodsThe diabetic retinopathy rat model was established.Rats were randomly divided into three groups (normal,diabetic,and diabetic with puerarin injection).The pathological changes of the retinopathy were examined.PEDF was analyzed with PCR in different time point.Results Body weight of diabetic group [ ( 216.9 ± 8.37 ) g,and(179.1 ±7.56)g] was compared with normal group[ (298.2 -±6.78)g,and(323.5 -±6.45)g] in the 3 month and 5 month ( q =12.39,P ＜0.01 ; q =15.47,P ＜0.01 ).Blood glucose of diabetic group and diabetic with puerarin injection group was compared with normal group at each time point ( P ＜ 0.01,P ＜ 0.05 ).HE staining of the retina of diabetic rats indicated a diabetic retinopathy occurred in the early - stage in diabetic group,but changed slightly in the diabetic model with an injection of puerarin.The PEDF expression at the 5 month time point in normal group,diabetic group,and diabetic group with puerarin injection was 8.833 (1.200),1.650(3.300),and 8.350( 1.100),respectively.Compared with normal group and diabetic group with puerarin injection,the level of PEDF was significantly decreased in diabetic group (x2 =48.57,P ＜ 0.01 ;x2=48.46,P ＜ 0.01 ).ConclusionsPuerarin can alleviate the retinal pathological damage of diabetic rats,early intervention with puerarin can prevent from the expression of PEDF and delay the diabetic retinopathy process.
ABSTRACT
This study was aimed to construct Sirt1 shRNA interfering vector and to analyze the effects of Sirtl on cell proliferation and apoptosis in HepG2, A549 and 293T cell lines. To design and synthisize Sirtl shRNA sequence then recombinate it to pGenesil-1.0 plasmid, the positive pGenesil-1.0-Sirtl vector clone was screened by effective detections and sequencing. The vectors were transfected into HepG2, A549, 293T cell lines, and Sirtl expression levels in these clones were detected by RT-PCR and Western-blot. These clone cell proliferation activities were detected by MTT, and these cells apoptosis incidences were detected by MTT experiment after treated with DOX. The results showed that Sirt1 shRNA interfering vectors were successfully screened. The levels of Sirtl expression in HepG2-sh, A549-sh and 293T-sh cells were significantly reduced compared with their control cells. It was indicated that the proliferation activities of these cells were impaired and anti-apoptosis capabilities of HepG2-sh, A549-sh and 293T-sh were also impaired notably. Sirt1 took an important role in maintaining cell proliferation and resisting cell apoptosis caused by DNA damage, and this result also provided theoretical information for the further research.
