ABSTRACT

Traumatic fractures and stress fractures are common orthopedic diseases, and there is great potential in researching bone turnover, repair, and promotion of fracture healing. Basic medical experiments often use animal models of long bone fractures in limbs to study the mechanisms of various interventions on fracture healing. Fracture healing is a complex process influenced by multiple factors and involves multiple molecules and pathways. Therefore, to explore the mechanisms more deeply, accelerate the translation of results, and improve the clinical efficacy, it is particularly important to choose the appropriate animal fracture modeling methods in experimental research. Based on this, this paper conducts a literature review of animal species and modeling methods commonly used for long bone fracture models in experimental research. It summarizes five methods: bone defect method, physical impact method, mechanical bending method, open osteotomy method, and drilling method. A side-by-side comparison of their advantages, disadvantages, and scope of application is made, aiming to provide suitable fracture models for studying the mechanisms of fracture healing interventions.

ABSTRACT

AIM: To investigate the protective effect of salvianolic acid B on retina and its influence on angiogenesis in retinal vein occlusion(RVO)injured rats.METHODS: SD rats were randomly divided into control group, model group and salvianolic acid B group, with 10 rats in each group. In addition to the control group, rats in model group and salvianolic acid B group were induced RVO by Bengal red combined with laser photodynamic method. The rats in salvianolic acid B group were intraperitoneally injected with salvianolic acid B 50 mg/(kg·d), while the rats in control group and model group were only given the same amount of normal saline for 21 consecutive days. Fundus fluorescein angiography(FFA)was used to observe the retinal vein structure before and after administration. HE staining was used to observe the pathological changes of rat retina. The retinal function of rats was evaluated by electroretinogram(ERG). The fluorescence expression of vascular endothelial growth factor A(VEGFA)in retina of rats in each group was detected by immunofluorescence staining. The relative expression of HIF-1α, STAT3, p-STAT3 and VEGFA proteins in retinal tissue were detected by Western blotting.RESULTS: Compared with the control group, the blood flow at the retinal obstruction in the model group was recanalized, and the effective collateral circulation was abundant, but the shape was irregular, and there was fluorescence leakage. In salvianolic acid B group, the retinal vein circulation recovered, the shape became regular gradually, and the collateral vessels decreased. The retina of the model group and salvianolic acid B group showed different degrees of pathological damage. At the same time, the amplitude of ERG a wave and b wave, the thickness of retinal total layer(RTL), inner nuclear layer(INL)and outer nuclear layer(ONL)decreased, the fluorescence intensity of VEGFA enhanced, and the relative expression of HIF-1α, p-STAT3 and VEGFA protein increased(P&#x0026;#x003C;0.05). Compared with the model group, the retinal histopathological damage of salvianolic acid B rats was alleviated, the amplitude of ERG a-wave and b-wave, the thickness of RTL, INL and ONL were increased, the fluorescence intensity of VEGFA was weakened, and the relative expression of HIF-1α, p-STAT3 and VEGFA proteins was decreased(P&#x0026;#x003C;0.05).CONCLUSION: Salvianolic acid B can alleviate the retinal histopathological injury and improve retinal function in RVO rats, which may be related to inhibiting the activation of HIF-1α/STAT3/VEGFA pathway and reducing angiogenesis.

ABSTRACT

AIM: To investigate the effects of ginsenoside Rg1 injection combined with inosine tablets and vitamin B1 on serum brain-derived neurotrophic factor(BDNF), pituitary adenylate cyclase activating polypeptide(PACAP)and clinical efficacy in primary retinitis pigmentosa.METHODS: A total of 50 patients(100 eyes)with primary retinitis pigmentosa who admitted to the Department of Ophthalmology, the Second Affiliated Hospital of Hebei North University from August 2019 to March 2022 were selected as the research object. They were divided into the study group and the control group according to random number table, with 50 eyes in each group. Patients in the control group were treated with inosine tablets and vitamin B1, while patients in the study group were treated with ginsenoside Rg1 injection on the basis of the control group. The expression of BDNF and PACAP in serum, electroretinogram and spectral-domain optical coherence tomography(SD-OCT)were compared before and after treatment, and the retinal thickness(RT), mean deviation(MD), clinical efficacy and safety indexes were compared between the two groups.RESULTS: There were no differences in the MD of the two groups before treatment(t=1.670, P=0.098), while the MD of the study group was significantly lower than that of the control group after treatment(t=3.628, P&#x003C;0.01). Before treatment, RT with a diameter of 1mm at the circle of macular fovea was compared between the two groups(t=0.108, P=0.914), it was significantly higher than that in the control group after treatment(t=6.125, P&#x003C;0.01). Before treatment, there was no significant difference in the results of dark adaptation of electroretinogram between the two groups(all P&#x003E;0.05). After treatment, the results of dark adaptation in the study group were significantly better than those in the control group(all P&#x003C;0.01). Before treatment, there was no significant difference in the results of electroretinogram adaptation between the two groups(all P&#x003E;0.05). After treatment, the results of electroretinogram adaptation in the study group were significantly better than those in the control group(all P&#x003C;0.01). There was no significant difference in BDNF and PACAP between the two groups before treatment(all P&#x003E;0.05). BDNF and PACAP in the study group were higher than those of the control group after treatment(all P&#x003C;0.01). After treatment, no adverse reactions were observed in both groups.CONCLUSION: The treatment of patients with primary retinitis pigmentosa with ginsenoside will improve the retinal function and promote the prognosis of the disease by regulating the expression of BDNF and PACAP, and it is highly safe.

ABSTRACT

Objective@#Individuals with dementia are at a substantially elevated risk for mortality; however, few studies have examined multimorbidity patterns and determined the inter-relationship between these comorbidities in predicting mortality risk. @*Methods@#This is a prospective cohort study. Data from 6,556 patients who were diagnosed with dementia between 1997 and 2012 using the Taiwan National Health Insurance Research Database were analyzed. Latent class analysis was performed using 16 common chronic conditions to identify mortality risk among potentially different latent classes. Logistic regression was performed to determine the adjusted association of the determined latent classes with the 5-year mortality rate. @*Results@#With adjustment for age, a three-class model was identified, with 42.7% of participants classified as “low comorbidity class (cluster 1)”, 44.2% as “cardiometabolic multimorbidity class (cluster 2)”, and 13.1% as “FRINGED class (cluster 3, characterized by FRacture, Infection, NasoGastric feeding, and bleEDing over upper gastrointestinal tract).” The incidence of 5-year mortality was 17.6% in cluster 1, 26.7% in cluster 2, and 59.6% in cluster 3. Compared with cluster 1, the odds ratio for mortality was 9.828 (95% confidence interval [CI]=6.708–14.401; p<0.001) in cluster 2 and 1.582 (95% CI=1.281–1.953; p<0.001) in cluster 3. @*Conclusion@#Among patients with dementia, the risk for 5-year mortality was highest in the subpopulation characterized by fracture, urinary and pulmonary infection, upper gastrointestinal bleeding, and nasogastric intubation, rather than cancer or cardiometabolic comorbidities. These findings may improve decision-making and advance care planning for patients with dementia.

ABSTRACT

Acute kidney injury (AKI) is an acute and critical kidney disease that seriously threatens human health and even life. It can lead to the chronic kidney disease (CKD) and end-stage kidney disease (ESRD), causing global public health problems. At present, the transition mechanism from AKI to CKD has not been fully elucidated, and renal tubular injury may play an important role in it. This paper reviews the role of renal tubular injury in the transition from AKI to CKD including cell dedifferentiation, inflammatory cell infiltration, hypoxia and vascular density decline, mitochondrial dysfunction and oxidative stress, G2/M cell cycle arrest, autophagy, TGFβ signaling pathway and Wnt signaling pathway.

ABSTRACT

While immune checkpoint inhibitors(ICIs)are effective and promising treatments for a variety of malignancies,they also have safety concerns,especially the immune-related adverse events(irAEs).Unlike the side effects of traditional chemotherapy and targeted therapy,irAEs are adverse events caused by immune activation after ICIs treatment and thus may involve almost every system of the body.Therefore,biomarkers for predicting irAEs after ICIs treatment are urgently needed.Here we review the currently available predictive biomarkers of irAEs.

ABSTRACT

Background: Lyso-thermosensitive liposomal doxorubicin (LTLD, ThermoDox) consists of doxorubicin encapsulated contained within a heat-sensitive liposome. Aims and Objectives: We sought to evaluate whether the use of combined radiofrequency ablation (RFA) and LTLD would result in larger coagulation volume and longer overall survival (OS) compared with the use of RFA alone in patients with 3–7 cm unresectable hepatocellular carcinoma (HCC). Materials and Methods: Between 2010 and 2012, 22 HCC patients were randomly assigned to one of two treatments in our center: (1) ultrasound-guided percutaneous RFA plus intravenous (IV) infusion of LTLD (combination, n = 11) or (2) RFA plus IV dummy (RFA, n = 11). Four patients withdrew from the study, and the remaining 18 patients entered the final analysis. There were 14 male and 4 female patients with an average age of 61.1 ± 9.3 years (range: 40–73 years). The average tumor size was 4.2 ± 1.0 cm (range: 3.1–6.1 cm). One-month enhanced computed tomography was used to evaluate the ablation efficacy and coagulation volume after RFA. Regular follow-up after RFA was performed to assess toxicity, local response rates, and OS rates. Results: A major complication (empyema) occurred in one case in the combination group. Combination treatment region did not induce any additional toxicity beyond doxorubicin. The primary ablation success rate was 93.3% (14/15 tumors) in the combination group and 77.8% (7/9 tumors) in the RFA group (P = 0.308). The difference in coagulation volume between pre- and post-RFA in the combination group was significantly larger than that of the RFA group (105.7 ± 73.8 cm 3 vs. 37.3 ± 8.5 cm 3, P = 0.013). The follow-up period ranged from 11 to 80 months (average: 49.1 ± 24.8 months). The local progression rate was 6.7% (1/15 tumors) in the combination group and 22.2% (2/9 tumors) in the RFA group. The mean OS for the combination group was 68.5 ± 7.2 months, which was significantly greater compared with the RFA group (46.0 ± 10.6 months, P = 0.045). Conclusions: RFA with heat target delivery chemotherapy facilitated better tumor coagulation necrosis without additional toxicity. This combined treatment may improve the clinical efficacy of RFA or free doxorubicin and prolong survival in patients with medium to large HCC

ABSTRACT

OBJECTIVE@#Antimicrobial resistance (AMR) has become a global concern and is especially severe in China. To effectively and reliably provide AMR data, we developed a new high-throughput real-time PCR assay based on microfluidic dynamic technology, and screened multiple AMR genes in broiler fecal samples.@*METHODS@#A high-throughput real-time PCR system with an new designed integrated fluidic circuit assay were performed AMR gene detection. A total of 273 broiler fecal samples collected from two geographically separated farms were screened AMR genes.@*RESULTS@#The new assay with limits of detection ranging from 40.9 to 8,000 copies/reaction. The sensitivity rate, specificity rate, positive predictive value, negative predictive value and correct indices were 99.30%, 98.08%, 95.31%, 99.79%, and 0.9755, respectively. Utilizing this assay, we demonstrate that AMR genes are widely spread, with positive detection rates ranging from 0 to 97.07% in 273 broiler fecal samples. blaCTX-M, blaTEM, mcr-1, fexA, cfr, optrA, and intI1 showed over 80% prevalence. The dissemination of AMR genes was distinct between the two farms.@*CONCLUSION@#We successfully established a new high-throughput real-time PCR assay applicable to AMR gene surveillance from fecal samples. The widespread existence of AMR genes detected in broiler farms highlights the current and severe problem of AMR.

ABSTRACT

OBJECTIVE@#To identify the effectiveness of auricular acupressure (AA) in patients with acute postoperative pain after surgery by systematic review.@*METHODS@#A search of randomized controlled trials was conducted in 5 English medical electronic databases and 4 Chinese databases. Two reviewers independently retrieved related studies, assessed the methodological quality, and extracted data with a standardized data form. Meta-analyses were performed using all time-points meta-analysis.@*RESULTS@#A total of 26 studies with 1,682 participants were included. Results showed that compared with conventional therapy, AA significantly improved the total effective rate [risk ratio=1.25, 95% confidence interval (CI), 1.13 to 1.37, Plt;0.0001; heterogeneity: Plt;0.0001, I=85%]. In the subgroup analysis, the results changed in different follow-up time and surgery categories. The pain relief in the AA group might be the most significant at 72 h after surgery (mean difference=-0.85, 95% CI,-1.20 to-0.50, Plt;0.0001) and in abdominal surgery (mean difference=-1.15, 95% CI,-1.41 to-0.90, Plt;0.0001). Sensitivity analysis demonstrated that the results of this meta-analysis were stable. No serious adverse effects were recorded.@*CONCLUSION@#It was recommended to provide AA to patients with acute postoperative pain. However, a more accurate estimate of the effect requires further rigorously designed large-scale and high-quality RCTs for improving acute postoperative pain after surgery.

ABSTRACT

Objective To investigate the expression of α-smooth muscle actin(α-SMA)in advanced colorectal cancer tissue and its association with chemotherapy response and prognosis.Methods The expression of α-SMA was detected by immunohistochemistry in tissues from 52 advanced colorectal cancer patients who received oxaliplatin plus 5-fluorouracil regimen as first-line chemotherapy. Its relationship with clinical characteristics,chemotherapy response,and survival were analyzed.Results Of these 52 patients,29(55.8%)were α-SMA overexpression,and the expression of α-SMA protein was not significantly associated with the age(χ =0.113,P=0.730),gender(χ =0.515,P=0.332),tumor location(χ =3.675,P=0.159),and tissue differentiation(χ =1.852,P=0.604). The chemotherapy resistance rate was 65.5%(19/29)in patients with high α-SMA expression,which was significantly higher than that (13.0%,3/23)in patients with low α-SMA expression(χ =14.470,P=0.000). Patients with high α-SMA expression exhibited a significantly shorter progression-free survival(PFS)compared with those with low α-SMA expression [(6.4±1.0)months vs.(16.0±3.5)months; χ=5.985,P=0.018]. Conclusion High α-SMA expression is associated with resistance to first-line chemotherapy and poor prognosis in advanced colorectal cancer patients.

ABSTRACT

Objective To explore the efficacy and prognostic factors of cetuximab therapy for KRAS or all RAS wild-type(WT)metastatic colorectal cancer(mCRC).Methods We screened mCRC patients receiving at least two cycles of cetuximb and chemotherapy from those with KRAS WT(before November 2013)or all-RAS-WT(after November 2013)in the Department of Medical Oncology,Peking Union Medical College Hospital from November 2007 to December 2016. The relationship between the clinicopathological characteristics and the efficacy was retrospectively analyzed.Results A total of 60 patients were included. For the 34 patients receiving cetuximab as first-line treatment,the objective response rate(ORR)was 55.9%,and the progression-free survival and overall survival(OS)was 10 and 24 months,respectively. All-RAS-WT mCRC had significantly lower risk of progression than those with KRAS-only-WT(P=0.012),and left-sided colorectal cancer had higher ORR than right-sided colon cancer(62.1% vs. 0,P=0.033)during the first-line treatment. The median OS of the eight patients continuing cetuximab beyond first-line progression was 35.0(95%CI:23.6-46.4)months.Conclusions The efficacy of cetuximab for left-sided colorectal cancer was better than for right-sided colon cancer,and patients with all-RAS-WT have lower risk of progression than those with KRAS-only-WT. Patients benefiting from first-line cetuximab and continuing cetuximab beyond progression survive longer.
