RESUMO

The syndrome differentiation of Yin and Yang has the function of controlling the other six principles in the eight principles syndrome differentiation,which is a higher level or general induction of the disease. In the clinical process of traditional Chinese medicine,syndrome differentiation of Yin and Yang runs through the whole process of disease diagnosis and treatment. For Parkinson's disease,syndrome differentiation of Yin and Yang is particularly important. Different symptoms,the transformation of pathogenesis during the development of the disease and the treatment of traditional Chinese and western medicine all reflect the characteristics of Yin and Yang opposition restriction,mutual root and mutual use,and the transformation of ebb and flow. This article discusses the background,application and value of Yin-Yang syndrome differentiation from three aspects:the origin and application of yin-yang syndrome differentiation,the basis of Parkinson's disease syndrome differentiation,and the status and role of Yin-Yang syndrome differentiation in Parkinson's disease. It is of great significance to guide the diagnosis and treatment of Parkinson's disease with "Yin-Yang as the key point".

RESUMO

AIM: To observe the efficacy of phacoemulsification combined with capsular tension ring and intraocular lens implantation in the treatment of high myopia with cataract.METHODS: Retrospective study. A total of 82 cases(82 eyes)of high myopia complicated with cataract who admitted to the cataract department of our hospital from December 2021 to April 2023 were selected as study objects, and they were divided into control group(n=39)and combination group(n=43)according to whether or not the capsular tension ring was used intraoperatively. Patients in the control group were treated with intraocular lens implantation alone, and those in the combination group were treated with phacoemulsification combined with capsular tension ring and intraocular lens implantation. The preoperative and postoperative best corrected visual acuity, central anterior chamber depth, trabecular ciliary process, visual quality and complications were compared.RESULTS: At 1 mo after surgery, the best corrected visual acuity(LogMAR)of both groups increased significantly(combination group: 0.64±0.28 vs 0.12±0.14; control group: 0.62±0.26 vs 0.23±0.25, both P<0.001). Central anterior chamber depth in both groups were higher than those before surgery(combination group: 2.57±0.56 vs 1.97±0.40 mm; control group: 2.22±0.45 vs 1.89±0.37 mm; both P<0.001), and the best corrected visual acuity and central anterior chamber depth of the combination group were significantly better than those of the control group(both P<0.05). The distance of trabecular ciliary process showed no statistical significance(combination group: 0.68±0.22 vs 0.74±0.20 mm; control group: 0.74±0.19 vs 0.78±0.17 mm, both P>0.05). The visual quality scores of the combination group were all higher than the control group at 1 mo after surgery [watching TV: 3.00±0.38 vs 2.22±0.46 points; reading books: 2.85±0.42 vs 2.21±0.44 points; night vision: 2.71±0.34 vs 2.37±0.41 points; fine operation: 2.82±0.38 vs 2.33±0.40 points, all P<0.001]. The incidence of complication in the combination group was significantly lower than that of the control group(33% vs 14%, P<0.05).CONCLUSION: Phacoemulsification combined with capsular tension ring and intraocular lens implantation can effectively promote the recovery of visual function, improve the structure of chamber angle, and reduce the incidence of complications in the treatment of patients with high myopia and cataract.

RESUMO

Periodontitis is an oral infectious disease that occurs in the tooth supporting tissues, which damages the soft and hard tissues of the periodontium and eventually results in tooth mobility and loss. Traditional clinical treatment can effectively control the periodontal infection and inflammation. However, as the therapeutic effect depending on the local condition of periodontal defect and the systemic factors of patients, it's hard to achieve satisfactory and stable periodontal tissue regeneration for damaged periodontal tissues. Recently, as a promising therapeutic strategy in periodontal regeneration, mesenchymal stem cells (MSC) play an important role in modern regenerative medicine. Combined with the clinical translational researches of MSC in periodontal tissue engineering and the research results of our group in the past decade, it is summarized and explained the mechanism of MSC promoting periodontal regeneration, the preclinical and the clinical transformation researches as well as the future application prospects of MSC in periodontal regeneration therapy in this paper.

RESUMO

Objective: To investigate the response characteristics of patients with locally advanced/metastatic non-squamous non-small cell lung cancer (nsq-NSCLC) treated with tislelizumab in combination with chemotherapy in the first line. Methods: Patients with nsq-NSCLC who achieved complete or partial remission after treatment with tislelizumab in combination with chemotherapy or chemotherapy alone in the RATIONALE 304 study, as assessed by an independent review board, were selected to analyze the response characteristics and safety profile of the responders. Time to response (TTR) was defined as the time from randomization to the achievement of first objective response. Depth of response (DpR) was defined as the maximum percentage of tumor shrinkage compared with the sum of the baseline target lesion length diameters. Results: As of January 23, 2020, 128 patients treated with tislelizumab in combination with chemotherapy achieved objective tumor response (responders), representing 57.4%(128/223) of the intention-to-treat population, with a TTR of 5.1 to 33.3 weeks and a median TTR of 7.9 weeks. Of the responders (128), 50.8%(65) achieved first remission at the first efficacy assessment (week 6), 31.3%(40) at the second efficacy assessment (week 12), and 18.0%(23) at the third and subsequent tumor assessments. The percentages of responders who achieved a depth of tumor response of 30% to <50%, 50% to <70% and 70% to 100% were 45.3%(58/128), 28.1%(36/128) and 26.6%(34/128), respectively, with median progression-free survival (PFS) of 9.0 months (95% CI: 7.7 to 9.9 months), 11.5 months (95% CI: 7.7 months to not reached) and not reached (95% CI: 11.8 months to not estimable), respectively. Tislelizumab plus chemotherapy were generally well tolerated in responders with similar safety profile to the overall safety population. Conclusion: Among responders to tislelizumab in combination with chemotherapy for nsq-NSCLC, 82.0%(105/128) achieves response within the first two tumor assessments (12 weeks) and 18.0%(23/128) achieves response at later (18 to 33 weeks) assessments, and there is a trend toward prolonged PFS in responders with deeper tumor response.

RESUMO

OBJECTIVE@#To examine the anti-inflammatory effect of grape seed extract (GSE) in animal and cellular models and explore its mechanism of action.@*METHODS@#This study determined the inhibitory effect of GSE on macrophage inflammation and Th1 and Th17 polarization in vitro. Based on the in vitro results, the effects and mechanisms of GSE on multiple sclerosis (MS)-experimental autoimmune encephalomyelitis (EAE) mice model were further explored. The C57BL/6 mice were intragastrically administered with 50 mg/kg of GSE once a day from the 3rd day to the 27th day after immunization. The activation of microglia, the polarization of Th1 and Th17 and the inflammatory factors such as tumor necrosis factor- α (TNF- α), interleukin-1 β (IL-1 β), IL-6, IL-12, IL-17 and interferon-γ (IFN-γ) secreted by them were detected in vitro and in vivo by flow cytometry, enzyme linked immunosorbent assay (ELISA), immunofluorescence staining and Western blot, respectively.@*RESULTS@#GSE reduced the secretion of TNF-α, IL-1 β and IL-6 in bone marrow-derived macrophages stimulated by lipopolysaccharide (P<0.01), inhibited the secretion of TNF-α, IL-1 β, IL-6, IL-12, IL-17 and IFN-γ in spleen cells of EAE mice immunized for 9 days (P<0.05 or P<0.01), and reduced the differentiation of Th1 and Th17 mediated by CD3 and CD28 factors (P<0.01). GSE significantly improved the clinical symptoms of EAE mice, and inhibited spinal cord demyelination and inflammatory cell infiltration. Peripherally, GSE downregulated the expression of toll-like-receptor 4 (TLR4) and Rho-associated kinase (ROCKII, P<0.05 or P<0.01), and inhibited the secretion of inflammatory factors (P<0.01 or P<0.05). In the central nervous system, GSE inhibited the infiltration of CD45+CD11b+ and CD45+CD4+ cells, and weakened the differentiation of Th1 and Th17 (P<0.05). Moreover, it reduced the secretion of inflammatory factors (P<0.01), and prevented the activation of microglia (P<0.05).@*CONCLUSION@#GSE had a beneficial effect on the pathogenesis and progression of EAE by inhibiting inflammatory response as a potential drug and strategy for the treatment of MS.

RESUMO

BACKGROUND@#Epidemiological surveys on heart failure (HF) in Chinese community are relatively lacking. This study aimed to estimate the prevalence and incidence of HF among community residents in southern China.@*METHODS@#Baseline data of this prospective study was collected from 2015 to 2017 among 12,013 permanent residents aged ≥ 35 years in Guangzhou, China. The same survey process was carried out for individuals aged ≥ 65 years after a three-year follow-up.@*RESULTS@#The overall prevalence of HF in community residents aged ≥ 35 years was 1.06%. Male had significantly higher risk of HF prevalence [odds ratio (OR) = 1.50, P = 0.027]. The gender-adjusted risk of HF was 1.48 times higher per 10 years aging. HF prevalence was statistically associated with atrial fibrillation, valvular heart disease, hypertension and chronic obstructive pulmonary disease after adjusting for age and gender (OR = 8.30, 5.17, 1.11, 2.28, respectively; all P < 0.05). HF incidence in individuals aged ≥ 65 years were 847 per 100,000 person-years. Baseline atrial fibrillation, valvular heart disease, and diabetes mellitus were risk factors for HF incidence for individuals aged ≥ 65 years adjusting for age and gender (OR = 5.05, 3.99, 2.11, respectively; all P < 0.05). Besides, residents with new-onset atrial fibrillation and myocardial infarction were at significantly higher risk of progression to HF (OR = 14.41, 8.54, respectively; all P < 0.05).@*CONCLUSIONS@#Both pre-existing and new-onset cardiovascular diseases were associated with HF incidence in southern China. Management of related cardiovascular diseases may be helpful to reduce the incidence of HF.

RESUMO

Cardiovascular disease (CVD) is a major contributor to patient deaths worldwide, and its pathogenesis is complex and mortality rates are increasing every year. Numerous researches have shown that the gut microbiota and its metabolites were closely associated with the development of CVD, and gut microbiota was expected to be a potential new target for the treatment of CVD. Traditional Chinese medicine (TCM), characterized by its multi-component, multi-target and integrity, can play a therapeutic role in CVD by regulating the gut microbiota, which has obvious advantages in stabilizing the disease, improving heart function and enhancing quality of life, and is an ideal intestinal microecological regulator. Therefore, this review will mainly discuss the intimate association of gut microbiota and its metabolites with CVD, and the therapeutic strategies of TCM targeting gut microbiota to improve CVD, including regulating the composition of gut microbiota, protecting the intestinal mucosal barrier, influencing the intestinal immune function and modulating the metabolites of gut microbiota, in order to provide a reference for the research of TCM targeting gut microbiota for CVD.

RESUMO

Anthocyanidin reductase (ANR) is one of the key enzyme in the flavonoid biosynthetic pathway, and its catalytic activity is important for the synthesis of plant anthocyanin. In this study, specific primers were designed according to the transcriptome data of Lonicera japonica Thunb., and the CDS, gDNA and promoter sequences of ANR genes from Lonicera japonica Thunb. and Lonicera japonica Thunb. var. chinensis (Wats.) Bak. were cloned. The results showed that the CDS sequences of LjANR and rLjANR were 1 002 bp, the gDNA sequences were 2 017 and 2 026 bp respectively, and the promoter sequences were 1 170 and 1 164 bp respectively. LjANR and rLjANR both contain 6 exons and 5 introns, which have the same length of exons and large differences in introns. The promoter sequences both contain a large number of light response, hormone response and abiotic stress response elements. Bioinformatics analysis showed that both LjANR and rLjANR encoded 333 amino acids and were predicted to be stable hydrophobic proteins without transmembrane segments and signal peptides. The secondary structures of LjANR and rLjANR were predicted to be mainly consisted of α-helix and random coil. Sequence alignment and phylogenetic analysis showed that LjANR and rLjANR had high homology with Actinidia chinensis var. chinensis, Camellia sinensis and Camellia oleifera, and were closely related to them. The expression levels of LjANR and rLjANR were the highest in flower buds and the lowest in roots. The expression patterns at different flowering stages were similar, with higher expression levels in S1 and S2 stages and then gradually decreased until reaching the lowest level in S4 stage, after a slow increase in S5 stage, the expression levels decreased again. The expression levels of ANR genes in the two varieties showed significant differences in roots, S2 and S5 stages, while the differences in stems, flower buds, S1, S3 and S6 stages were extremely significant. The prokaryotic expression vector pET-32a-LjANR was constructed for protein expression. The target protein was successfully expressed of about 59 kD. This study lays a foundation for further study on the function of ANR gene and provides theoretical guidance for breeding new varieties of Lonicera japonica Thunb.

RESUMO

ObjectiveTo investigate whether phosphodiesterase (PDE) 5 inhibitors sildenafil (SIL) or LW1646 prevented renal interstitial fibrosis induced by unilateral ureteral obstruction (UUO). MethodsMale C57BL/6 mice were randomly divided into four groups (n =6), namely the Sham group, 7UUO group, 7UUO+SIL group and 7UUO+LW1646 group. Sildenafil (SIL) or LW1646, or vehicle was administered 1 hour before surgery, and the mice were continuously treated once daily (i. g., 50 mg/kg) for 7 days. The obstructed kidneys were harvested on day 7. Hematoxylin-eosin (HE) and Masson’s staining was used to examine renal histology. Immunoblotting and RT-qPCR were used to detect the expression levels of protein and mRNA for fibrosis, apoptosis, endoplasmic reticulum (ER) stress, autophagy, and pro-fibrotic factors. Human proximal tubule epithelial cells (HK-2) were treated with TGF-β1 for 48 hours or tunicamycin for 24 hours, respectively, to evaluate whether cyclic guanosine monophosphate (cGMP) or PDE5 inhibitors prevents ER stress and pro-fibrotic responses. ResultsAt the 7th days after UUO, the body weight of the mice showed a significant decrease (P< 0.000 1) compared with that in the sham group. The obstructed kidneys showed a significant tubular dilation and interstitial inflammation. The levels of protein and mRNA expression in apoptosis, ER stress, autophagy-related protein and pro-fibrotic factors were also markedly increased in UUO mice (P <0.05). In contrast, SIL or LW1646 treatment was associated with attenuated tubular dilation, infiltration of inflammatory cells and collagen content in the obstructed kidney of the mice. The protein and mRNA expression levels of renal TGF-β1 were markedly decreased, and the protein expression levels of apoptosis, endoplasmic reticulum stress, and autophagy markers were also significantly downregulated by PDE5 inhibitors. In HK-2 cells, TGF-β1 induced increased expression levels of fibronectin and BiP, which was at least partially reversed by cGMP, a product of PDE inhibition. Additionally, PDE5 inhibitors were found to modulate aberrant levels of autophagy and apoptosis. ConclusionIn conclusion, PDE5 inhibitors, in particular, LW1646, can alleviate the progression of fibrosis by improving ER stress, apoptosis and autophagy as well as downregulating protein and mRNA expression of TGF-β1.

RESUMO

Objective: To explore the diagnosis, surgical management and outcome of jugular foramen chondrosarcoma (CSA). Methods: Fifteen patients with jugular foramen CSA hospitalized in the Department of Otorhinolaryngology Head and Neck Surgery of Chinese PLA General Hospital from December 2002 to February 2020 were retrospectively collected,of whom 2 were male and 13 were female, aging from 22 to 61 years old. The clinical symptoms and signs, imaging features, differential diagnosis, surgical approaches, function of facial nerve and cranial nerves IX to XII, and surgical outcomes were analyzed. Results: Patients with jugular foramen CSA mainly presented with facial paralysis, hearing loss, hoarseness, cough, tinnitus and local mass. Computed tomography (CT) and magnetic resonance (MR) could provide important information for diagnosis. CT showed irregular destruction on bone margin of the jugular foramen. MR demonstrated iso or hypointense on T1WI, hyperintense on T2WI and heterogeneous contrast-enhancement. Surgical approaches were chosen upon the sizes and scopes of the tumors. Inferior temporal fossa A approach was adopted in 12 cases, inferior temporal fossa B approach in 2 cases and mastoid combined parotid approach in 1 case. Five patients with facial nerve involved received great auricular nerve graft. The House Brackmann (H-B) grading scale was used to evaluate the facial nerve function. Preoperative facial nerve function ranked grade Ⅴ in 4 cases and grade Ⅵ in 1 case. Postoperative facial nerve function improved to grade Ⅲ in 2 cases and grade Ⅵ in 3 cases. Five patients presented with cranial nerves Ⅸ and Ⅹ palsies. Hoarseness and cough of 2 cases improved after operation, while the other 3 cases did not. All the patients were diagnosed CSA by histopathology and immunohistochemistry, with immunohistochemical staining showing vimentin and S-100 positive, but cytokeratin negative in tumor cells. All patients survived during 28 to 234 months' follow-up. Two patients suffered from tumor recurrence 7 years after surgery and received revision surgery. No complications such as cerebrospinal fluid leakage and intracranial infection occurred after operation. Conclusions: Jugular foramen CSA lacks characteristic symptoms or signs. Imaging is helpful to differential diagnosis. Surgery is the primary treatment of jugular foramen CSA. Patients with facial paralysis should receive surgery in time as to restore the facial nerve. Long-term follow-up is necessary after surgery in case of recurrence.

RESUMO

@#Objective    To explore the effect of LeCompte maneuver on in-hospital mortality and mid-to-long term reintervention after single-stage arterial switch operation in children with side-by-side Taussig-Bing anomaly. Methods     Clinical data of patients diagnosed with side-by-side Taussig-Bing anomaly and undergoing single-stage arterial switch operation in Shanghai Children’s Medical Center from 2006 to 2017 were retrospectively analyzed. Patients were divided into two groups based on whether LeCompte maneuver was performed: a LeCompte maneuver group and a non LeCompte maneuver group. The clinical data of two groups were compared. Results    Finally 92 patients were collected. LeCompte maneuver was performed in 32 out of 92 patients with a median age of 65.0 days and an average weight of 4.3 kg, among whom 24 (75.0%) were male. Fifteen (46.9%) patients received concomitant aortic arch repair while 12 (37.5%) patients were associated with coronary artery malformation. LeCompte maneuver was not performed in 60 patients with a median age of 81.0 days and an average weight of 4.8 kg, among whom 45 (75.0%) were male. Twenty-two (36.7%) patients received concomitant aortic arch repair while 35 (58.3%) patients were associated with coronary artery malformation. The average cardiopulmonary bypass duration of the LeCompte maneuver group showed no statistical difference from the non LeCompte maneuver group (179.0±60.0 min vs. 203.0±74.0 min, P=0.093). The in-hospital mortality of the two groups were 6 (18.8%) and 7 (11.7%), respectively, which also showed no statistical difference (P=0.364). The median follow-up period was 4.1 (1.6, 7.5) years for 79 patients with 8 lost to follow-up, and no death was observed. Kaplan-Meier curve and log-rank test showed no statistical difference in overall mid-to-long term reintervention rate (P=0.850) as well as right ventricular outflow tract and pulmonary artery reintervention rate (P=0.240) with or without LeCompte maneuver. Conclusion    Whether or not to perform LeCompte maneuver shows no statistical impact on in-hospital mortality and mid-to-long term reintervention rate of single-stage arterial switch operation for side-by-side Taussig-Bing anomaly.

RESUMO

Objective:In order to determine the development potential of human embryos in vitro, amino acid and carnitine levels were measured in the culture medium of different grades of early human embryos. Methods:From the infertile couples who received in vitro fertilization-embryo transfer treatment in the Department of Reproductive Medicine of Linyi People′s Hospital from June 2022 to December 2022, the age of the women was defined as 25-35 years old [31.5(26.5, 33.25)] with 8-20 eggs, 126 cultured cells and embryos of the third day were randomly collected from infertile couples. They were divided into three groups according to the morphological level of the corresponding embryos: excellent, neutral and poor. Amino acids and L-carnitines levels in culture medium were detected by liquid chromatography-mass spectrometry (LC-MS). Using analysis of variance to compare differences among groups, correlation analysis, factor analysis was performed to analyze the association between the levels of amino acids and L-carnitines and development potential of early human embryos.Results:The value of Methionine/Phenylalanine was found statistically different among superior embryo (3.09±1.67), moderate embryo (4.00±1.19) and inferior embryo (4.99±2.04). The difference between the three groups was statistically different ( F=7.09, P<0.05): superior embryo vs moderate embryo ( t=-0.91, P<0.05), superior embryo vs inferior embryo ( t=-1.91, P<0.05), moderate embryo vs inferior embryo ( t=-0.99, P<0.05). Among different amino acids, Phe had the strongest positive correlation with Tyr ( r=0.99, P<0.01). Among different carnitines, C 8/C 10 has the strongest positive correlation with C 5DC+C 6OH/C 16( r=0.44, P<0.01). The weight value of leucine (isoleucine), arginine, valine/phenylalanine, glycine, tyrosine and carnitine(C 5DC+C 6OH)/C 8 calculated by the least square fitting model is 2.22, 1.99, 1.65, 1.54, 1.21 and 1.15 respectively. Conclusion:Leucine, arginine, valine/phenylalanine, glycine, tyrosine and carnitine (C 5DC+C 6OH)/C 8 in embryo culture medium were significantly correlated with the levels of early human embryos in vitro.

RESUMO

Objective:We evaluated frailty in elderly hospitalized patients with atrial fibrillation and analyzed the relevance, consistency, and diagnostic power of different frailty tools.Methods:From September 2018 to April 2019, a total of 197 elderly patients with atrial fibrillation aged ≥ 65 years in Beijing Hospital, Chinese PLA General Hospital, and Beijing Tsinghua Changgung Hospital were prospectively enrolled.Five frailty tools, including the clinical frailty scale(CFS), FRAIL scale(FRAIL), Fried frailty phenotype(Fried), Edmonton frail scale(EFS), and comprehensive geriatric assessment-frailty index(CGA-FI), were used for frailty assessment.Results:A total of 197 hospitalized elderly patients with atrial fibrillation were enrolled, with an average age of(77.5±7.1)years old(57.4% male). The prevalence of frailty, according to the five frailty tools, were 25.4%(FRAIL), 27.9%(EFS), 34.5%(Fried), 40.6%(CFS), and 42.6%(CGA-FI), respectively.CFS had a good correlation(correlation coefficient 0.80)and and consistency(Kappa value 0.71, 95% CI 0.61~0.81)with CGA-FI.The combined frailty index was used as the gold standard for frailty diagnosis.The results showed that CFS and CGA-FI had high diagnostic sensitivity(95.9 % and 98.0 %, respectively)and specificity(77.7 % and 75.7 %, respectively). Conclusions:Frailty is common in elderly hospitalized patients with atrial fibrillation, showing multidimensional features, and physical weakness is not prominet.CFS and CGA-FI are recommended for the assessment of frailty in patients with atrial fibrillation, which had good correlation and consistency.

RESUMO

Type II deiodinase (DIO2) is thought to provide triiodothyronine (T3) to the nucleus to meet intracellular needs by deiodinating the prohormone thyroxine. DIO2 is expressed widely in many tissues and plays an important role in a variety of physiological processes, such as controlling T3 content in developing tissues (e.g., bone, muscles, and skin) and the adult brain, and regulating adaptive thermogenesis in brown adipose tissue (BAT). However, the identification and cloning of DIO2 have been challenging. In recent years, several clinical investigations have focused on the Thr92Ala polymorphism, which is closely correlated with clinical syndromes such as type 2 diabetes, obesity, hypertension, and osteoarthritis. Thr92Ala-DIO2 was also found to be related to bone and neurodegenerative diseases and tumors. However, relatively few reviews have synthesized research on individual deiodinases, especially DIO2, in the past 5 years. This review summarizes current knowledge regarding the physiological functions of DIO2 in thyroid hormone signaling and adaptive thermogenesis in BAT and the brain, as well as the associations between Thr92Ala-DIO2 and bone and neurodegenerative diseases and tumors. This discussion is expected to provide insights into the physiological functions of DIO2 and the clinical syndromes associated with Thr92Ala-DIO2.

RESUMO

Aim To explore the mechanism of grape seed proanthocyanidins (GSPs) targeting astrocytes (AS), so as to regulate the phenotype and function of AS and maximize their neuroprotective effect. Methods The effects of GSPs on the phenotype, secretion of pro-inflammatory factors and neurotrophic factors of Al AS induced by TNF-α, IL-1α and Clq were investigated by RT-PCR, Elisa and Western blot in vitro. And JNK phosphorylation was determined using Western blot. Results GSPs significantly reduced the expression of C3d and Clq of Al AS markers and inhibited the phosphorylation of JNK. Moreover, compared with the model group, GSPs could significantly inhibit the release of pro-inflammatory cytokines IL-6, IL-1 α, IL-17 and H

RESUMO

Aim To predict the targets of Modified Danggui Shaoyao San ( MDSS) in the treatment of chronic atrophic gastritis ( CAG) based on network pharmacology and vertify the results based on experim-ention. Methods TCMSP, SWISS TARGETS, GENE CARDS and OMIM databases were used to screen the therapeutic targets of MDSS for CAG. STRING database and Cytoscape software were used to construct the protein interaction network and screen the core targets. Metascape database was used for GO analysis and KEGG enrichment pathways. And molecular docking was used for target validation. CAG rat model was pre¬pared by N-methyl-N'-nitroso-N-nitroguanidine free drink combined with sodium salicylate gastric lavage. The pathology of rat gastric mucosa was observed by hematoxylin-eosin staining,and the ultrastructure of ep¬ithelial cells was observed by transmission electron mi-croscopy. The serum IL-6 and IL-10 content was detected by enzyme-linked immunosorbent assay, and the expression of JAK2, STAT3 , p-STAT3 , c-MYC mRNA and protein in rats was detected by qPCR and Western blot. Results MDSS acted on 189 targets, mainly involved in response to oxidative stress and apoptotic signaling pathway. KEGG analysis related to pathways in cancer and JAK-STAT signaling pathway. The experimental results showed that the MDSS could improve the degree of atrophy of gastric mucosa in CAG rats and improve the status of epithelial cells, down-regulate the serum IL-6 content of CAG rats, up-regulate the IL-10 content, and reduce the expression of JAK2, STAT3 , p-STAT3 , c-MYC mRNA and protein in gastric mucosa with statistical significance. Conclusions MDSS treats CAG through multiple active ingredients, targets, and pathways, the mechanism of which may be related to the inhibition of the JAK2/STAT3 signaling pathway.

RESUMO

PURPOSE@#The study aims to compare the efficacy and safety of a new minimally invasive osteosynthesis technique with those of conventional open surgery for transverse patellar fractures.@*METHODS@#It was a retrospective study. Adult patients with closed transverse patellar fracture were included, and with open comminuted patellar fracture were excluded. These patients were divided into minimally invasive osteosynthesis technique (MIOT) group and open reduction and internal fixation (ORIF) group. Surgical time, frequency of intraoperative fluoroscopy, visual analogue scale score, flexion, extension, Lysholm knee score, infection, malreduction, implant migration and implant irritation in two groups were recorded and compared. Statistical analysis was performed by the SPSS software package (version 19). A p < 0.05 indicated statistical significance.@*RESULTS@#A total of 55 patients with transverse patellar fractures enrolled in this study, the minimally invasive technique was performed in 27 cases, and open reduction was performed in 28 cases. The surgical time in the ORIF group was shorter than that in the MIOT group (p = 0.033). The visual analogue scale scores in the MIOT group were significantly lower than those in the ORIF group only in the first month after surgery (p = 0.015). Flexion was restored faster in the MIOT group than that in the ORIF group at one month (p = 0.001) and three months (p = 0.015). Extension was recovered faster in the MIOT group than that in the ORIF group at one month (p = 0.031) and three months (p = 0.023). The recorded Lysholm knee scores in the MIOT group were always greater than those in the ORIF group. Complications, such as infection, malreduction, implant migration, and implant irritation, occurred more frequently in the ORIF group.@*CONCLUSION@#Compared with the ORIF group, the MIOT group reduced postoperative pain and had less complications and better exercise rehabilitation. Although it requires a long operation time, MIOT may be a wise choice for transverse patellar fractures.

RESUMO

OBJECTIVE@#To analyze the difference in the gene expression, amino acid and carnitine levels in the cervical secretions between the endometria of pre-receptive and receptive stages, with an aim to provide clues for identifying new molecular markers for endometrial receptivity.@*METHODS@#Fifty nine infertile women treated at the Department of Reproductive Medicine of Linyi People's Hospital from January 6, 2020 to January 31, 2022 were selected as as the study subjects, which were matched with 3 pairs (6 cases) of infertile women preparing for embryo transfer based on factors such as age, body mass index, and length of infertility. Endometrial tissue samples were collected for gene transcription and expression analysis. Twenty five women who had become pregnant through assisted reproductive technology were selected as the control group, and 28 non-pregnant women receiving ovulation monitoring at the Outpatient Department were enrolled as the case group. Status of endometrial receptivity was determined by ultrasonography. In the former group, endometrial tissues were sampled for sequencing, and GO and KEGG database enrichment analysis of differentially expressed genes was carried out. In the latter group, cervical secretions were collected, and amino acid and carnitine levels were measured by mass spectrometry. Statistical analysis was carried out using rank sum test, t test and chi-square test with SPSS v25.0 software.@*RESULTS@#No difference was found in the clinical data of the patients with regard to age, body mass index, infertility years, AMH, FSH, LH, E2, and type of infertility. Compared with the receptive endometrial tissues, there were 100 significantly up-regulated genes and 191 significantly down-regulated genes in the pre-receptive endometrial tissue, with the most significantly altered ones being HLA-DRB5 and MMP10. The biological processes, molecular functions and pathways enriched by more differentially expressed genes in GO and KEGG were mainly immune regulation, cell adhesion and tryptophan metabolism. Analysis of secretion metabolism also revealed a significant difference in the levels of amino acids and carnitine metabolites between the two groups (P < 0.05), in particular those of Alanine, Valine, 3-hydroxybutyrylcarnitine (C4OH) + malonylcarnitine (C3DC)/captoylcarnitine (C10).@*CONCLUSION@#A significant difference has been discovered in the levels of gene transcription and protein expression in the endometrial tissues from the pre-receptive and receptive stages. The levels of amino acids and carnitine, such as Alanine, Valine, 3-hydroxybutyryl carnitine (C4OH)+malonyl carnitine (C3DC)/caproyl carnitine (C10), may be associated with the receptive status of the endometrium, though this need to be verified with larger samples.
