ABSTRACT

Objective:To investigate the effect of tripartite motif-containing 23 (Trim23) on the differentiation and maturation of dendritic cells and the possible mechanism.Methods:Mouse bone marrow-derived dendritic cells (BMDCs) were prepared from bone marrow cells of C57BL/6 mice with the presence of Flt3L. Real-time quantitative PCR and Western blot were used to detect the expression of Trim23 in BMDCs after LPS stimulation. An overexpression vector for full-length Trim23 (Trim23 OE) was constructed and transfected into BMDCs, and the pcDNA3.1 empty vector was used as control. Flow cytometry was used to detect the expression of CD80, CD86, CD40 and MHCⅡ on the surface of vector-transfected BMDCs after LPS stimulation and ELISA was used to detect the secretion of IL-12p40, TNF-α, IL-6 and IL-10 by these cells. CD8 + and CD4 + T cells were isolated from spleen and lymph nodes of OT-Ⅰ and OT-Ⅱ mice by magnetic beads and co-cultured with LPS-treated BMDCs in the presence of ovalbumin (OVA). Flow cytometry was used to detect the proliferation and differentiation of CD8 + and CD4 + T cells. Western blot was performed to analyze the phosphorylation of p38, ERK1/2 and AKT in BMDCs. Two overexpression vectors for Trim23 mutants lacking RING or ARF domain (Trim23 ΔRING and Trim23 ΔARF) were constructed and transfected into BMDCs. Then flow cytometry and ELISA were used to detect the expression of surface molecules and cytokines. Results:The expression of Trim23 in BMDCs was significantly down-regulated after LPS stimulation. The expression of MHCⅡ, CD86 and CD80 and the secretion of TNF-α and IL-6 decreased significantly in BMDCs overexpressing Trim23. Furthermore, overexpression of Trim23 inhibited the ability of BMDCs to induce the proliferation and differentiation of CD4 + T cells and the proliferation of CD8 + T cells. Western blot showed that the phosphorylation of p38 and ERK1/2 decreased significantly in Trim23-overexpressing BMDCs. Compared with wildtype Trim23, overexpression of Trim23 ΔRING had no significant influence on the expression of surface molecules (MHCⅡ and CD86) and the secretion of cytokines (TNF-α and IL-6) in BMDCs stimulated by LPS. Conclusions:Trim23 overexpression inhibited the maturation and immune activation of BMDCs via MAPK signal pathway and its RING domain. This study provided reference for targeting Trim23 to improve the immune response of dendritic cell-based tumor vaccines.

ABSTRACT

Objectives: To examine the short-term and mid-term effects of surgical treatment of obstructive hypertrophic cardiomyopathy (HCM) in one center. Methods: The perioperative data and short-term follow-up outcomes of 421 patients with obstructive HCM who received surgical treatment at Department of Cardiac Surgery, Zhongshan Hospital, Fudan University from January 2017 to December 2021 were analyzed retrospectively. There were 207 males and 214 females, aged (56.5±11.7) years (range: 19 to 78 years). Preoperative New York Heart Association (NYHA) classification included 45 cases of class Ⅱ, 328 cases in class Ⅲ, and 48 cases in class Ⅳ. Fifty-eight patients were diagnosed with latent obstructive HCM and 257 patients had moderate or more mitral regurgitation with 56 patients suffering from intrinsic mitral valve diseases. All procedures were completed by a multidisciplinary team, including professional echocardiologists involving in preoperative planning for proper mitral valve management strategies and intraoperative monitoring. A total of 338 patients underwent septal myectomy alone, and 59 patients underwent mitral valve surgery along with myectomy. A single transaortic approach was used in 355 patients, and a right atrial-atrial septal/atrial sulcus approach was used in 51 other patients. Long-handled minimally invasive surgical instruments were used for the procedures. Student t test, Wilcoxon rank sum test, χ2 test or Fisher exact test were used to compare the data before and after surgery. Results: The aortic cross-clamping time of septal myectomy alone was (34.3±8.5) minutes (range: 21 to 94 minutes). Eighteen patients had intraoperative adverse events and underwent immediate reoperation, including residual obstruction (10 patients), left ventricular free wall rupture (4 patients), ventricular septal perforation (3 patients), and aortic valve perforation (1 patient). Four patients died during hospitalization, and 11 patients developed complete atrioventricular block requiring permanent pacemaker implantation. After discharge, 384 (92.1%) patients received a follow-up visit with a median duration of 9 months. All follow-up patients survived with significantly improved NYHA classifications: 216 patients in class Ⅰ and 168 patients in class Ⅱ (χ2=662.73, P<0.01 as compared to baseline). At 6 months after surgery, follow-up echocardiography showed that the thickness of the ventricular septum ((13.6±2.5) mm vs. (18.2±3.0) mm, t=23.51, P<0.01) and the peak left ventricular outflow tract gradient ((12.0±6.3) mmHg vs. (93.4±19.8) mmHg, 1 mmHg=0.133 kPa, t=78.29, P<0.01) were both significantly lower than baseline values. Conclusion: The construction of the surgical team (including echocardiography experts), proper mitral valve management strategies, identification and management of sub-mitral-valve abnormalities, and application of long-handled minimally invasive surgical instruments are important for the successful implementation of septal myectomy with satisfactory short-and medium-term outcomes.

ABSTRACT

The purpose of this research is to identify the chemical constituents of sea buckthorn leaves extract (SBLE) and explore its hypoglycemic biological activity. SBLE was prepared by hot reflux extraction with 65% ethanol, and its chemical composition was analyzed by ultra-high-performance liquid chromatography-photodiode array-mass spectrometry/mass spectrometry (UHPLC-PDA-MS/MS) system. The animal experiments were compliant with ethical principles for animal use and had been approved by the Animal Experiment Ethics Committee of Jinan University. Mice were injected with streptozocin (STZ) to establish a hyperglycemic animal model, and SBLE (1.5 g·kg-1) was administered by gavage for 5 weeks. The fasting blood glucose (FBG) and oral glucose tolerance were detected. Normal mice were given SBLE (1.5 g·kg-1) by intragastric administration for 10 days, and blood was collected from the tail vein to detect the changes in blood glucose within 120 min after sucrose or starch loading. The mucous membrane of the small intestine of mice was taken to detect the activity of α-glucosidase (AG), and the activity of yeast-derived AG incubated with SBLE was evaluated. The glucose uptake by Caco-2 cells treated with SBLE was detected by fluorescence microscopy and cytometry, and the gene expression of sodium-dependent glucose transporter 1 (SGLT1) and glucose transporter 2 (GLUT2) in Caco-2 cells were detected by real-time quantitative PCR (qPCR). A total of 18 compounds were identified, mainly including tannins and flavonoids. SBLE reduced FBG and increased oral glucose tolerance in STZ hyperglycemic mice. SBLE effectively inhibited the increase of blood glucose caused by starch intake in normal mice. SBLE exerted good inhibitory activity on yeast-derived AG (IC50 = 16.94 μg·mL-1) and small intestinal mucosa AG with an inhibition rate of 15.48%. SBLE (25-100 μg·mL-1) dose-dependently inhibited glucose uptake by Caco-2 cells, and SBLE significantly reduced the mRNA level of SGLT1 without changing the expression of GLUT2. In conclusion, the UHPLC characteristic fingerprint of SBLE is established with 18 chemical components identified by mass spectrometry, and SBLE exerts hypoglycemic effect by inhibiting the activity of AG and the absorption of glucose by intestinal epithelial cells.

ABSTRACT

OBJECTIVES@#To study the change in asymmetric dimethylarginine (ADMA) in the circulation system of full-term infants with persistent pulmonary hypertension of the newborn (PPHN) and its association with treatment response, as well as the possibility of ADMA as a therapeutic target and a marker for treatment response.@*METHODS@#A prospective study was performed. A total of 30 full-term neonates who were diagnosed with PPHN within 3 days after birth were enrolled as the PPHN group, and the neonates without PPHN, matched for gestational age and age, who were treated or observed in the department of neonatology were enrolled as the control group. Serum samples were collected on days 1, 7, and 14 of treatment. The high-performance liquid chromatography-tandem mass spectrometry was used to measure the serum concentrations of L-arginine, ADMA, and its isomer symmetric dimethylarginine (SDMA).@*RESULTS@#For the neonates in the control group, the serum concentrations of ADMA and L-arginine continuously increased and the serum concentration of SDMA continuously decreased within the first 14 days of treatment. On days 1 and 14, there was no significant difference in the serum concentration of ADMA between the control and PPHN groups (P>0.05). On day 7, the PPHN group had a significantly higher serum concentration of ADMA than the control group (P<0.05), while there were no significant differences in serum concentrations of SDMA or L-arginine (P>0.05). Moreover, after 7 days of treatment, the PPHN neonates with a systolic pulmonary arterial pressure (sPAP) of >35 mmHg had a significantly higher serum concentration of ADMA than those with an sPAP of ≤35 mm Hg.@*CONCLUSIONS@#There are continuous increases in the ADMA concentration and the ADMA/SDMA ratio in the circulation system of full-term infants within the first 2 weeks after birth, and this process is accelerated by the pathological process of PPHN, suggesting that ADMA may be involved in the pathologic process of PPHN. A high level of ADMA is associated with the resistance to PPHN treatment, suggesting that inhibition of ADMA might be a potential target of drug intervention to improve the treatment response of PPHN.

ABSTRACT

Circadian rhythm is mainly regulated by circadian clock genes, which is the result of biological evolution and plays an important role in maintaining the normal structure and function of organisms. When the circadian rhythm is disturbed or out of balance, it will have adverse health consequences. In addition to studies on diseases of nervous system, endocrine system or cardiovascular system, it has been found that circadian rhythm disorder mediated by circadian clock gene also plays a key regulatory role in the occurrence and development of hepatocellular carcinoma, which is a potential diagnostic marker and therapeutic target. In this paper, the research on the role of circadian clock gene in hepatocellular carcinoma in recent years is reviewed, and the research progresis and existing problems of targeting circadian clock gene in the treatment of hepatocellular carcinoma are discussed.

ABSTRACT

Objective To investigate the prevalence of Schistosoma japonicum infection in wild mice in Shitai County, Anhui Province, so as to provide insights into precise control of the source of S. japonicum infections. Methods Wild mice were captured using the trapping method for three successive nights at snail-infested settings from Jitan Village of Jitan Township, and Shiquan Village and Xibai Village of Dingxiang Township, Shitai County, Anhui Province in June and October, 2018. All trapped wild mice were sacrificed and liver and mesenteric vein specimens were collected for detection of S. japonicum eggs using microscopy, while the fecal samples in mouse intestines were collected for identification of S. japonicum infections using Kato-Katz technique. In addition, the population density of trapped wild mice was estimated and the prevalence of S. japonicum infection was calculated in trapped wild mice. Results A total of 376 wild mice were trapped from three villages in Shitai County. The population density of trapped wild mice was 9.1% (376/4 124), and the prevalence of S. japonicum infection was 24.2% (91/376) in trapped wild mice. The highest prevalence of S. japonicum infection was detected in Shiquan Village of Dingxiang Township (30.1%), and the lowest prevalence was seen in Xibai Village of Dingxiang Township; however, there was no significant difference in the prevalence of S. japonicum infection in trapped wild mice among three villages (χ2= 4.111, P > 0.05). In addition, there was no significant difference in the prevalence of S. japonicum infection in wild mice captured between on June (26.8%, 34/127) and October (22.9%, 57/249) (χ2 = 0.690, P = 0.406). The trapped wild mice included 6 species, including Rattus norvegicus, Niviventer niviventer, R. losea, Apodemus agrarius, Mus musculus and N. coning, and the two highest prevalence of S. japonicum infection was detected in R. losea (34.9%, 22/63) and R. norvegicus (31.2%, 44/141). Conclusions The prevalence of S. japonicum infections is high in wild mice in Shitai County, and there is a natural focus of schistosomiasis transmission in Shitai County.

ABSTRACT

Background/Aims@#Cigarette smoking is an important modifiable risk factor in kidney disease progression. However, the underlying mechanisms for this are lacking. This study aimed to assess whether nicotine (NIC), a major toxic component of cigarette smoking, would exacerbates tacrolimus (TAC)-induced renal injury. @*Methods@#Sprague-Dawley rats were treated daily with NIC, TAC, or both drugs for 4 weeks. The influence of NIC on TAC-caused renal injury was examined via renal function, histopathology, oxidative stress, mitochondria, endoplasmic reticulum (ER) stress, and programmed cell death (apoptosis and autophagy). @*Results@#Both NIC and TAC significantly impaired renal function and histopathology, while combined NIC and TAC treatment aggravated these parameters beyond the effects of either alone. Increased oxidative stress, ER stress, mitochondrial dysfunction, proinf lammatory and profibrotic cytokine expressions, and programmed cell death from either NIC or TAC were also aggravated by the two combined. @*Conclusions@#Our observations suggest that NIC exacerbates chronic TAC nephrotoxicity, implying that smoking cessation may be beneficial for transplant smokers taking TAC.

ABSTRACT

Objective:To investigate the effects of β-glucan combined with agonistic anti-CD40 monoclonal antibody (5C11) on the immune functions of dendritic cells (DCs) and the possible molecular mechanism.Methods:Mononuclear cells were separated from fresh concentrated white cells (granulocytes) of healthy subjects using Ficoll density gradient centrifugation, and induced by GM-CSF and IL-4 to differentiate into immature DCs. Following various stimulation (5C11 alone, β-glucan alone, 5C11 combined with β-glucan), flow cytometry was used to detect the expression of CD40, CD80, CD83, CD86 and MHC-Ⅱ molecule HLA-DR on the surface of DCs. ELISA was used to detect the secretion of cytokines including IL-12, IL-6, TNF-α and IL-10. Western blot was used to detect the phosphorylation of proteins related to MAPK signaling pathway.Results:Flow cytometry suggested that β-glucan significantly induced the expression of co-stimulatory molecule CD40 on the surface of DCs ( P<0.05). After the DCs were co-stimulated with β-glucan and 5C11, CD80, CD83 and CD86 expression were further significantly increased, and a strong synergistic effect on CD83 expression, a key marker of DC maturation, was observed ( P<0.01). ELISA showed that β-glucan combined with 5C11 could significantly promote the secretion of cytokines such as IL-12, IL-6 and TNF-α by DCs, and have a synergistic effect on the secretion of IL-12, a critical cytokine in regulating DC functions ( P<0.01). Western blot indicated that the phosphorylation of p38 MAPK and p44/42 MAPK in DCs was increased significantly after combined treatment, and the phosphorylation started earlier and lasted longer compared to that in DCs stimulated with 5C11 or β-glucan alone ( P<0.01). Conclusions:This study suggested that β-glucan combined with 5C11 had a synergistic effect on promoting the maturation and improving the immune functions of DCs, providing a new strategy for the preparation of anti-tumor DC vaccines.

ABSTRACT

Aloin is a small-molecule drug well known for its protective actions in various models of damage. Traumatic brain injury (TBI)-induced cerebral edema from secondary damage caused by disruption of the blood-brain barrier (BBB) often leads to an adverse prognosis. Since the role of aloin in maintaining the integrity of the BBB after TBI remains unclear, we explored the protective effects of aloin on the BBB using in vivo and in vitro TBI models. Adult male C57BL/6 mice underwent controlled cortical impact injury, and mouse brain capillary endothelial bEnd.3 cells underwent biaxial stretch injury, then both received aloin treatment. In the animal experiments, we found 20 mg/kg aloin to be the optimum concentration to decrease cerebral edema, decrease disruption of the BBB, and improve neurobehavioral performance after cortical impact injury. In the cellular studies, the optimum concentration of 40 μg/mL aloin reduced apoptosis and reversed the loss of tight junctions by reducing the reactive oxygen species levels and changes in mitochondrial membrane potential after stretch injury. The mechanisms may be that aloin downregulates the phosphorylation of p38 mitogen-activated protein kinase, the activation of p65 nuclear factor-kappa B, and the ratios of B cell lymphoma (Bcl)-2-associated X protein/Bcl-2 and cleaved caspase-3/caspase-3. We conclude that aloin exhibits these protective effects on the BBB after TBI through its anti-oxidative stress and anti-apoptotic properties in mouse brain capillary endothelial cells. Aloin may thus be a promising therapeutic drug for TBI.

ABSTRACT

Objective@#To explore the clinical application value of enhanced recovery after surgery (ERAS) in the laparoscopic surgery for cholecystolithiasis comorbid with choledocholithiasis.@*Methods@#The prospective study was conducted. The clinicopathological data of 52 patients with cholecystolithiasis comorbid with choledocholithiasis who were admitted to the Third Affiliated Hospital of Zunyi Medical University from September 2016 to September 2018 were collected. Patients were divided into 2 groups by random number table: patients in observation group received laparoscopic cholecystectomy + choledocholithotomy + choledochoscopic exploration + T-tube drainage (or primary suture of common bile duct) and perioperative management guided by the concept of enhanced recovery after surgery (ERAS), and patients in control group received traditional perioperative management. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) postoperative complications; (4) postoperative pain scores; (5) changes in hepatic function and blood routine during perioperative period. Follow-up using outpatient examination and telephone interview was performed to detect complications during the postoperative 6 months up to March 2019. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the paired t test or repeated ANOVA. Count data were described as absolute numbers and percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability.@*Results@#Fifty-two patients were screened for eligibility, including 20 males and 32 females, aged 25-68 years, with an average age of 53 years.

ABSTRACT

Estimation of postmortem interval(PMI)plays a crucial role in forensic study and identifica-tion work. Because of the unique anatomy location, vitreous humor is considered to be used for estima-ting PMI, which has aroused interest among scholars, and some researches have been carried out. The detection techniques of vitreous humor are constantly developed and improved which have been gradually applied in forensic science, meanwhile, the study of PMI estimation using vitreous humor is updated rapidly. This paper reviews various techniques and instruments applied to vitreous humor detection, such as ion selective electrode, capillary ion analysis, spectroscopy, chromatography, nano-sensing technology, automatic biochemical analyser, flow cytometer, etc., as well as the related research progress on PMI es-timation in recent years. In order to provide a research direction for scholars and promote a more accu-rate and efficient application in PMI estimation by vitreous humor analysis, some inner problems are also analysed in this paper.

ABSTRACT

We investigated the clinical and epidemiological characteristics of laboratory confirmed cases of severe fever with thrombocytopenia syndrome (SFTS) in Shandong Province,China.A descriptive epidemiological method combined with case investigation was used in this study.Cases information were collected by standard questionnaire and analyzed by Epidata3.1,SPSS 17.0 and ArcGIS10.0 software.Results showed that a total of 154 cases were analyzed and the case fatality rate was 7.1%.Epidemic peak was from May to October,the high incidence areas were located in the middle and east hilly areas of Shandong Province.The characteristic of SFTS cases were farmers (93.5%),and the age was over 40 years.Most of them were living in the hilly areas (85.7 %),and had outdoor activities within the previous 2 weeks prior to fever onset (83.8 %).The 16.8% of them had tick bites history.Tick carrying rates of sheep,cattle,dogs and cats were 66.7%,40%,34.3% and 12.5%,respectively.Directly contact with bloody secretion of SFTS death cases can be infected with the disease.Major symptoms include high fever (98.1%),anorexia (90.9 %),fatigue (53.3%),thrombocytopenia (73.4 %) and leukocytopenia (60.4 %).The 35.7 % cases need to go through more than three referrals for treatment,the interval time between onset and diagnosis was 5 days(3-15),only hospitals above county level can make the correct diagnosis of the disease.Compared with survival patients,the death cases were elderly patients (t =2.03,P=0.044) and with bleeding performance (x2 =13.09,P<0.01).In conclusion,SFTS is a severe disease with high mortality.Living hilly environment,doing agricultural labor,feeding animals,tick carrying rates of animals and direct contacting with bloody secretion of deaths maybe possible risk factors.To reduce morbidity and mortality of SFTS,measures should be carried out to propagandize the basic knowledge for SFTS prevention and control and to improve the medical treatment skills of doctors in the epidemic foci.

ABSTRACT

BACKGROUND: Jefferson fracture associated with unstable odontoid fracture is rare, and little reported.Occipito-cervical fusion is the commonly used treatment method, but it causes a severe loss of the motion of cervical vertebrae, which affects the patients' quality of life, so the curative effect is poor.OBJECTIVE: To evaluate the feasibility and therapeutic efficacy of atlantoaxial transpedicular screw fixation for Jefferson fracture associated with unstable odontoid fracture, so as to avoid occipito-cervical fusion and preserve the motion of the atlanto-occipital joint.METHODS: Fifteen patients with Jefferson fracture associated with unstable odontoid fracture from March 2010 to August 2015, were treated with atlantoaxial transpedicular screw fixation. There were 13 cases of Anderson type II and 2 cases of Anderson shallow type lll odontoid fracture, as well as 5 cases combined with transverse atlantal ligament rupture. All patients underwent skull traction after admission, as well as three-dimensional CT was applied preoperatively to determine the atlas pedicle screw trajectory and chose suitable screws. Atlantoaxial transpedicular screw was placed and atlantoaxial joint was reduced under general anesthesia. Bone graft fusion of atlantoaxial joint was applied only for the transverse atlantal ligament.The pain and neurologic function were evaluated by the Visual Analog Scale and the American Spinal Injury Association Impairment Scale before and after operation. The range of motion of the atlanto-occipital joint was observed during follow-up.RESULTS AND CONCLUSION: (1) The mean operation time was (150±41) minutes (120-270 minutes). The mean blood loss was (246±95) mL (160-500 mL). (2) Atlantoaxial transpedicular screws were successfully placed in all patients. No spinal and nerve root injury, or vertebral artery injury occurred intraoperatively. The atlantoaxial achieved good reduction. (3) The follow-up time was 12-36 months. There were nine cases of incomplete spinal cord injury, and 7 cases of obviously improved neurologic function. The visual analog scale scores were significantly improved at 1 year postoperatively, from preoperative (8.15±0.62) to postoperative (1.2±1.4) (P < 0.05). (4) All fractures and bone grafts were healed without loosening or rupture of the screws. The range of motion of the atlanto-occipital joint was (14.6±2.8)° postoperatively. (5) To conclude, atlantoaxial transpedicular screw fixation is effective for Jefferson fracture combined with unstable odontoid fracture, which not only exhibits a high rate of bone healing and stable fixation, but also avoids the occipital-cervical fusion and preserves occipito-atlantal motion.

ABSTRACT

The electrospray ionization-ion mobility spectrometric (ESI-IMS) technique has the potential as an analytical separation tool in analyzing polypeptides and amino acids for fast screening unknown samples in anti-chemical and biological terror attacks. A method for detecting several polypeptides and amino acids was developed based on ESI-IMS using air as drift gas at room temperature. The ion mobility of four amino acids and two polypeptides dissolved in methanol was determined on the system at elution rate of 2 mL/ min. The spectra of these compounds had characteristics of finger-printing maps. The limit of detection of this instrument for Substance P could reach 855 ng / mL in 1 min. The results showed that a small, self-contained ESI-IMS instrument with reservoirs of air could be used to quickly detect and accurately identify polypeptides and amino acids.
