ABSTRACT
This paper aimed to explore the antidepressant effect of the essential oil from Schizonepeta tenuifolia Briq.(EOST) on the treatment of depression and its mechanism by using a combination of network pharmacology and the mouse model of lipopolysaccharide(LPS)-induced depression. The chemical components in EOST were identified using gas chromatography-mass spectrometer(GC-MS), and 12 active components were selected as the study objects. The targets related to EOST were obtained by Traditional Chinese Medicines Systems Pharmacology(TCMSP) and SwissTargetPrediction database. The targets related to depression were screened out through GeneCards, Therapeutic Target Database(TTD), and Online Mendelian Inheritance in Man(OMIM) database. The Venny 2.1 was applied to screen out the common targets of EOST and depression. The targets were imported into Cytoscape 3.7.2 to generate "drug-active component-diease-target" network diagram. The protein-protein interaction(PPI) network was constructed using STRING 11.5 database and Cytoscape 3.7.2, and the core targets were screened out. DAVID 6.8 database was used for Gene Ontology(GO) func-tional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis, and subsequently the enrichment results were visualized through the bioinformatics platform. The mouse model of depression was induced by intraperitoneally injecting with LPS in mice. Before modeling, mice were administrated orally with EOST. The antidepressant effect of EOST was evalua-ted by tail suspension test(TST), forced swimming test(FST), and novelty suppressed feeding test(NSFT) after modeling. The content of interleukin(IL)-1β was determined by enzyme-linked immunosorbent assay(ELISA), and the protein expression levels of IL-1β and pro IL-1β in the hippocampus were determined by Western blot. There were 12 main components and 179 targets in EOAT, of which, 116 targets were related to depression, mainly involved in neuroactive ligand-receptor interaction, calcium signaling pathway, and cyclic adenosine monophosphate(cAMP) signaling pathway. Biological processes such as synaptic signal transduction, G-protein coupled receptor signaling pathway, and chemical synaptic transmission were involved. Molecular functions such as neurotransmitter receptor activity, RNA polymerase Ⅱ transcription factor activity, and heme binding were involved. In mice experiments, the results showed that EOST at 100 mg·kg~(-1) and 50 mg·kg~(-1) significantly shortened the immobility time in TST and FST as well as the feeding latency in NSFT compared with the model group, decreased the levels of serum IL-1β and NO, and reduced the protein expression levels of IL-1β and pro IL-1β in the hippocampus. In conclusion, EOST shows a good antidepressant effect in a multi-component, multi-target, and multi-pathway manner. The mechanism may be attributed to the fact that EOST can down-regulate the protein expression levels of IL-1β and pro IL-1β, decrease the release of inflammatory factors, and reduce neuroinflammation response.

Objective:To observe the characteristics of macular telangiectasia (MacTel) in multi-color and multi-mode fundus images.Methods:An abservational case series study was conducted.Sixteen eyes of 12 patients diagnosed with MacTel by fluorescein fundus angiography (FFA) from January to November 2019 in Shandong Eye Hospital were analyzed.There were 8 cases (8 eyes) with MacTel type Ⅰ, among which 4 cases were male and 4 cases were female, with an average age of (62.3±12.5) years.The other 4 cases (8 eyes) had MacTel type Ⅱ, all of which were female, with an average age of (58.7±10.5) years.Best corrected visual acuity, slit lamp microscopy, color fundus photography, multicolor scanning laser imaging, FFA, optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) were carried out in all the patients.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Shandong Eye Institute (No.2019S003).Results:In color fundus images of MacTel type Ⅰ eyes, annular macular exudation with macular edema occurred in 6 eyes, macular edema without hard exudates in 1 eye, and hard macular exudates without macular edema in 1 eye.However, the transparency of retina in temporal fovea in MacTel type Ⅱ eyes decreased, showing a gray color.In multi-color fundus images of MacTel type Ⅰ eyes, punctate granular yellow macular exudation and yellow-green macular edema were observed, which were clearer than those in color fundus images.Punctate exudation was seen in both the blue and green reflectance images, which was clearest in green reflectance image, followed by blue reflectance image and then the infrared reflectance image.In OCT images of MacTel type Ⅰ eyes, cystoid edema of inner retina or uneven reflection signal of outer plexiform retina were observed.Loss of inner and outer retinal structures and cavities were observable in MacTel type Ⅱ eyes, and outer retinal atrophy appeared in 2 eyes.In OCTA images, the destruction of superficial and deep capillary plexus in macular area were observed in both MacTel typeⅠand type Ⅱ eyes, and the destruction of deep capillary plexus was more obvious.In addition, more obviously increased vascular space, decreased vessel density, and increased foveal avascular zone were found in MacTel type Ⅱ eyes.In early stage of FFA, delayed capillary filling near fovea was seen in MacTel typeⅠeyes, and dilated temporal vessels in fovea, some of which showed tumor-like dilation, and the limited tumor-like dilation was enhanced in the later stage.Different degrees of dilated parafoveal blood vessels in the early stage, and the capillary in the temporal side of the macula showing diffuse strong fluorescence in the late stage of FFA was observed in MacTel type Ⅱ eyes.Conclusions:Multi-color scanning laser imaging can be used to observe the morphological characteristics of MacTel, and the imaging features of different types of MacTel are significantly different.
ABSTRACT
Objective To explore the morphology and the tissue structure of acromioclavicular joint. Methods Anatomical analysis was performed on 27 fresh adult cadavers and the morphology of the acromioclavicular joint was observed. The relevant bone structure and ligament parameters were measured, and the specimens were randomly divided into group A and group B. Group A reserved the acromioclavicular ligament and coracoclavicular ligament, and group B reserved only the acromioclavicular ligament. The difference in tension between the two groups was compared. Results The distance from the midpoint of the conical ligament to the distal end of the clavicle was (42.68 ± 6.34) mm, the width of the end point was (16.97 ± 4.28) mm, and the thickness of the center point was (5.39 ± 0.34) mm; the distance from the midpoint of the trapezoidal ligament to the clavicle was (20.35 mm ± 4.18) mm, the width of the end point was (10.35± 1.31) mm, the thickness of the center point was (5.19 ± 0.342) mm; the average vertical distance from the base of the coracoid process to the surface of the clavicle was 30.75 mm, and the mean coracoclavicular gap was 12.02 mm; the length of the central axis of the conical ligament was (15.68 ± 3.30) mm and the angle was (117.25 ± 10.80) °, while the length of the central axis of the trapezoidal ligament was (9.67 ± 2.25) mm, and the angle was (75.42± 11.37) °. The distance between the start joint of the trapezoidal ligament and the trapezium was (8.96± 3.00) mm, and the distance between the end points (13.09± 3.50) mm. The average tensile force of group A was higher than that of group B [(610.04 ± 51.24) N vs (560.41 ± 44.63) N, P < 0.05]. Conclusion During distal clavicular resection, the resection of the distal clavicle shall be within 10-30 mm. The depth shall not exceed 42 mm when drilling under the coracoid process. The reconstruction of the coracoclavicular ligament during acromioclavicular joint dislocation has an anatomical and biomechanical basis.
ABSTRACT
Trisomy 11 mosaicism is clinically rare, for which making diagnostic and treatment decisions can be challenging. In this study, we used noninvasive prenatal testing, chromosome karyotype analysis, chromosome microarray analysis, copy number variation sequencing and fluorescence in situ hybridization for detecting trisomy 11 mosaicism in two cases and provided them with genetic counseling. In one of the cases, the fetus with confined placental mosaicism trisomy 11 presented with severe growth restriction and a placental mosaic level of 44%, and pregnancy was terminated at 25+3 weeks of gestation. In the other case with true low-level fetal mosaicism of trisomy 11, the pregnancy continued after exclusion of the possibility of uniparental disomy and structural abnormalities and careful prenatal counseling. The newborn was followed up for more than one year, and no abnormality was found. Noninvasive prenatal testing is capable of detecting chromosomal mosaicism but may cause missed diagnosis of true fetal mosaicism. For cases with positive noninvasive prenatal testing but a normal karyotype of the fetus, care should be taken in prenatal counseling and pregnancy management.

Objective: To investigate the molecular pathogenesis and clinical features of unrelated 12 patients with inherited coagulation protein C (PC) deficiency in Chinese population. Methods: The PC activity (PC:A) and PC antigen (PC:Ag) were detected by chromogenic substrate and enzyme linked immunosorbent assay, respectively. The nine exons and flanking sequences of the protein C (PROC) gene were amplified by polymerase chain reaction with direct sequencing, and the suspected mutations were validated by reverse sequencing (clone sequencing for deletion mutations) . Results: The PC:A of the 12 probands decreased significantly, ranging from 18% to 55%, and the PC:Ag of the 10 probands decreased significantly. Eleven mutations were found, out of which four mutations [c.383G>A (p.Gly128Asp) , c.997G>A (p.Ala291Thr) , c.1318C>T (p.Arg398Cys) , and c.532G>C (p.Leu278Pro) ] were discovered for the first time. Six mutations were in the serine protease domain, four mutations were located in epidermal growth factor (EGF) -like domains, and one mutation was located in activation peptide. There were two deletion mutations (p.Met364Trp fsX15 and p.Lys192del) , and the rest were missense mutations. Mutations p.Phe181Val and p.Arg189Trp were identified in three unrelated families. All mutations may be inherited, and consanguineous marriages were reported in two families. Among the probands, nine cases had venous thrombosis, two cases had poor pregnancy manifestations, and one case had purpura. Conclusion: Patients with PC deficiency caused by PROC gene defects are prone to venous thrombosis, especially when there are other thrombotic factors present at the same time.

@#Objective To summarize the experience of treating adult recurrent pectus excavatum without plate turnover. Methods Twenty-seven patients with recurrent pectus excavatum treated by thoracoscopy-assisted placement without plate turnover from 2010 to 2019 in our hospital were enrolled. There were 23 males and 4 females with the age of 3-29 (12.81±7.79) years at the first operation, and 18-29 (21.74±3.56) years at this operation. Incision of 2-3 cm at bilateral axillary midline of the deepest point of pectus excavatum was made, and an auxiliary incision under xiphoid process was adopted according to the intraoperative situation. Results All patients underwent thoracoscopy-assisted correction of pectus excavatum without bar turnover, and subxiphoid incision was performed in 11 patients. Twenty-five patients had one bar placed, and two patients required two bars. The operation time was 28-45 (33.00±6.44) min. Postoperative Haller index (2.95±0.40) was improved compared with preoperation (4.63±1.03). The postoperative hospital stay was 4-6 (4.00±0.32) day. All patients were followed up for 1-8 years. Complications included poor wound healing in 1 patient, and steel wire fracture and displacement in 1 patient. There was no plate rotation or bar displacement. Fourteen patients removed the bar 29-84 (40.36±13.93) months after the placement. Haller index was improved to 2.43-3.61 (2.86±0.35) during removal of steel plate. Untill June 2020, there was no recurrence of pectus excavatum. Conclusion The treatment of adult recurrent pectus excavatum without plate turnover is satisfactory, and the protection of intercostal muscle and firm fixation is the key to ensure the success of operation and long-term effects.
ABSTRACT
OBJECTIVE@#To compare clinical effects of different postoperative rehabilitation modes on lumbar degenerative diseases, and explore influence of rehabilitation mode and other factors on postoperative effect.@*METHODS@#From June 2013 to July 2016, totally 900 patients were admitted from nine tertiary hospitals in Beijing to perform single segment bone grafting and internal fixation due to lumbar degenerative diseases were prospectively analyzed. There were 428 males and 472 females, the age of patient over 18 years old, with an average of (51.42±12.41) years old;according to patients' subjective wishes and actual residence conditions, all patients were divided into three groups, named as observation group 1 (performed integrated rehabilitation approach and orthopedic treatment model intervention), observation group 2 (performed integrated rehabilitation approach and orthopedic treatment, classified rehabilitation model intervention), and control group(performed routine rehabilitation model intervention). Visual analogue scale(VAS), Oswestry Disability Index(ODI) and Japanese Orthopaedic Association (JOA) were used to evaluate postoperative efficacy among three groups at 24 weeks. Possible factors affecting the postoperative efficacy including age, age grouping, gender, body mass index (BMI), BMI grouping, education level, visiting hospital, payment method of medical expenses, preoperative complications, preoperative JOA score, clinical diagnosis, surgery section, operative method, intraoperative bleeding volume, postoperative complications and rehabilitation mode were listed as independent variables, and postoperative ODI score at 24 weeks as dependent variables. Univariate analysis was used to analyze relationship between influencing factors and postoperative efficacy. Multiple linear regression was used to analyze relationship between influencing factors, rehabilitation mode and postoperative ODI score at 24 weeks, in further to find out the main reasons which affect postoperative efficacy, and to analyze impact of rehabilitation mode on postoperative efficacy.@*RESULTS@#All patients were followed up for 24 weeks after operation. All incisions healed at stage I with stable internal fixation. (1)Evaluation of postoperative efficacy:① There were no statistical differences in preoperative VAS and ODI among three groups(@*CONCLUSION@#Preoperative JOA score, gender, age could predict postoperative clinical effects of lumbar degenerative diseases in varying degrees treated with single level bone graft fusion and internal fixation. Different rehabilitation modes could improve clinical effects. Intergrated rehabilitation orthopedic treatment model and integrated rehabilitation approach and orthopedic treatment with classifiedrehabilitation model are superior to conventional rehabilitation model in improving patients' postoperative function and relieving pain, which is worthy of promoting in clinical.

OBJECTIVE@#To analyze the molecular pathogenesis by analysis of phenotype and gene mutation in families with hereditary coagulation factor V (FⅤ) defect caused by complex heterozygous mutation.@*METHODS@#Plasma pro-thrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), FⅤ procoagulant activity (FⅤ∶C), FⅤ antigen (FⅤ∶Ag), and other related coagulation indexes were detected in the proband and his family members (3 generations 10 people). Using DNA direct sequencing to analyze all exons, flanks, 5' and 3' untranslated regions of F5 genes and the corresponding mutation site regions of family members, the mutation site was confirmed by reverse sequencing．The conservation of mutant amino acids was analyzed by ClustalX-2.1-win software. The PROVEAN and MutationTaster online bioinformatics software were used to predict the effect of mutation on protein function. Protein model and amino acid interaction at mutation sites was analyzed by Swiss-pdbviewer software.@*RESULTS@#The PT and APTT of the proband were significantly prolonged compared with healthy controls (34.2 vs 13.2 s and 119.3 vs 36.0 s), while FⅤ∶C and FⅤ∶Ag extremely reduced (3% and 6%). The PT and APTT of the second-born, the third son, daughter, and grandson of the proband were slightly prolonged, and the FⅤ∶C and FⅤ∶Ag decreased to varying degrees. The related coagulant parameters of other family members were within normal range. Genetic analysis revealed that the proband had a c.911G>A heterozygous missense mutation on the exon 6 lead to p.Gly276Glu, and a c.5343C>G heterozygous missense mutation on the exon 16 lead to p.Ser1781Arg of the proband. The second-born, the third son, and grandson of the proband carry p.Gly276Glu heterozygotes, and the daughter carries p.Ser1781Arg heterozygotes, while the other family members were wild-type. The results of conservative analysis indicated that p.Gly276 and p.Ser1781 were highly conserved in homologous species. The two bioinformatics software predicted the same results, PROVEAN (score -6.214 and -12.79) indicated that the compound heterozygous mutation was a harmful mutation; MutationTaster (score 0.976 and 0.999) suggested that these mutations might cause corresponding disease. p.Gly276Glu protein model analysis showed that, the Glu side chain was prolonged and the molecular weight became larger, which would increase the steric hindrance between it and the surrounding amino acids, affect the normal local folding of the FⅤ protein, and eventually lead to the decrease of protein activity and content. This paper can not provide analysis of the spatial structure of p.Ser1781Arg mutant protein because of the lack of X ray 3 D structure file of FⅤ exon 16.@*CONCLUSION@#The new compound heterozygous mutations (p.Gly276Glu and p.Ser1781Arg) identified in this study are the main reasons for the decrease in the FⅤ level of the family, among which p.Ser1781Arg is rarely reported at home and abroad.

ABSTRACT
Nonalcoholic fatty liver disease (NAFLD)is one of the most common chronic liver diseases in the world,and it is associated with obesity,hyperlipidemia,insulin resistance,and type 2 diabetes. Lipid deposition,insulin resistance,and inflammatory response may in-duce NAFLD,but detailed mechanism remains unknown. In - depth studies on the pathogenesis of NAFLD have found that macrophage,oxi-dative stress,and gut microbiota have certain influence on the pathogenesis of NAFLD,and regulation of macrophage polarization and appli-cation of carotenoids and anti - tumor necrosis factor may prevent or delay the progression of NAFLD. This article reviews the research ad-vances in potential therapies for NAFLD.

ABSTRACT
Objective To investigate the effect of microRNA-223-3p (miR-223-3p) on megakaryocytic differentiation and maturation, and explore the potential mechanism .Methods The endogenous expression of miR-223-3p during megakaryocyte ( MK) differentiation was detected by real-time PCR.Flow cytometry further indicated that alteration of miR-223-3p in human cell lines exerted effects on MK differentiation and maturation .By performing integrative bioinformatic analysis, the potential miR-223-3p target gene, MYH10,was identified.Real-time PCR, luciferase reporter assay and flow cytometry revealed that MYH10 was a direct target of miR-223-3p.Results Endogenous expression of miR-223-3p was in-creased with the differentiation and maturation of MK .The expression of megakaryocytic surface markers CD41 and CD61 and the ploidy were significantly increased in K562 and Meg-01 cells after transfection with miR-223-3p mimics.The expression of MYH10 decreased with the increase in miR-223-3p.Using a luciferase reporter assay ,we demonstrated that MYH10 was a direct target of MiR-223-3p.Furthermore, direct downregulation of MYH10 promoted MK polyploidization . Conclusion MiR-223-3p might regulate the polyploidization of MK by targeting MYH10.
ABSTRACT
Objective To investigate the effects of aspirin and clopidogrel on the risk of upper gastrointestinal bleeding in patients with cardiovascular and cerebrovascular diseases. Methods 116 cases of patients with upper gastrointestinal bleeding and cardiovascular disease as research subjects. 86 cases of patients used antiplatelet drugs (drug group), 30 cases didn't use antiplatelet drugs (non-drug group). In the drug group, 30 patients with aspirin alone (group A), 24 patients with clopidogrel alone (group B) and 32 patients with aspirin and clopidogrel (group C) . Compared the upper gastrointestinal bleeding in each group of patients. Results The incidence of abdominal pain in the drug group was significantly lower than non-drug group (P<0.05). However, there was no significant difference in the incidence of bloating, nausea, vomiting, acid reflux compared with non - drug group. There were no significant differences in the endoscopic manifestations of gastrointestinal bleeding between the drug group and the non-drug group. The incidence of severe gastrointestinal bleeding in the drug group was 47.67%, significantly higher than that in the non-drug group (26.67%)(P<0.05). A, B, C three groups of patients with severe gastrointestinal bleeding rate and bleeding patterns were no significant difference. There was no significant difference in the total effective rate of gastrointestinal bleeding between the drug group and the non-drug group. Conclusion Antiplatelet drugs may increase the risk of upper gastrointestinal bleeding in patients with cardiovascular and cerebrovascular diseases, but aspirin and clopidogrel alone or in combination had no significant effect on the degree of gastrointestinal bleeding.

Objective To discuss the clinical efficacy of hot-tonifying needling in treating stomachache due to deficient cold in spleen-stomach.Method Forty patients with stomachache due to deficient cold in spleen-stomach were divided into a treatment group and a control group by using random number table method according to registration order, 20 cases in each group. The control group was intervened by twisting tonifying method, while the treatment group was intervened by hot tonifying needling method. The Visual Analogue Scale (VAS) was observed before and after the treatment, and the clinical efficacies were compared.Result The VAS scores were significantly changed after the treatment in both groups (P<0.05); there was a significant difference in comparing the VAS score between the two groups after the treatment (P<0.05); the difference in the change of VAS score between the two groups was statistically significant (P<0.05). The total effective rate was 95.0％ in the treatment group, versus 60.0％ in the control group, and the difference was statistically significant (P<0.05), and there were significant differences in comparing the clinical efficacy and relapse rate between the two groups (P<0.05).Conclusion Hot-tonifying needling is effective in treating stomachache due to deficient cold in spleen-stomach, with less adverse effects and lower relapse rate.
