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

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 analyze the endemic situation of schistosomiasis in national surveillance sites of Anhui Province from 2015 to 2018, so as to provide scientific evidence for schistosomiasis control and prevention in Anhui Province. Methods According to the National Schistosomiasis Surveillance Programme (2014 version), a total of 51 national schistosomiasis surveillance sites were assigned in Anhui Province in 2015, and Schistosoma japonicum infections in humans and livestock and snail distribution were monitored from 2015 to 2018. Results A total of 89 638 local residents and 42 609 mobile populations received serological screening of schistosomiasis in 51 national surveillance sites of Anhui Province from 2015 to 2018, and the sero-prevalence of S. japonicum infections was 1.41% to 3.69% in local residents and 0.84% to 2.13% in mobile populations, respectively. There were 5 egg-positive local residents and 1 egg-positive mobile populations detected in 2015, with occupations of farmers and fishermen. There were 6 405 livestock detected for S. japonicum infections, and no egg-positives were identified. Among an area of 12 661 hm2 surveyed in the national schistosomiasis surveillance sites of Anhui Province from 2015 to 2018, the areas of snail habitats were 2 461.27 to 2 628.96 hm2, andthemeandensityoflivingsnailswas 0.3757 to 0.4330 snails/0.1 m2, with no S. japonicum infections identified in snails.

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

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

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.

ABSTRACT

OBJECTIVE:To observe the clinical efficacy of sitagliptin combined with benazepril in the treatment of diabetic nephropathy(DN). METHODS:Sixty DN patients admitted to our hospital during Sept. 2014-Jun. 2015 were divided into sitagliptin group,benazepril group,drug combination group according to random number table,with 20 cases in each group. Based on routine treatment,sitagliptin group was given sitagliptin 100 mg orally,qd;benazepril group was given Benazepril 10 mg orally,qd;drug combination group was given sitagliptin 100 mg+benazepril 10 mg orally,qd. The drug dosage would be doubled if the blood pressure of patients in 3 groups had not yet reached the standard. Treatment course of 3 groups lasted for 12 weeks. The levels of 24 h urine protein,IL-6 and Cys-C were measured in 3 groups before and after treatment. Clinical efficacies and the occurrence of ADR were observed. RESULTS:Total response rate of drug combination group(90.00%)was significantly higher than those of sitagliptin group (65.00%)and benazepril group(70.00%);there was statistically significance(P0.05). No obvious ADR was found in 3 groups during treatment. CONCLUSIONS:Both sitagliptin and benazepril can decrease the levels of 24 h urine protein,IL-6 and Cys-C,while drug combination shows better effect and clinical response rate,and does not influence the safety of drug use.

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.
