ABSTRACT

Objective:To investigate the application of therapeutic grade ionization chamber to rapid measurement of short pulsed and high-dose-rate X-ray.Methods:The half-value layer of pulsed X-ray caused by an electron accelerator was measured by interpolation method and its equivalent energy was estimated. The cumulative doses from a certain amount of pulsed radiation at different distances in the same direction around the equipment were compared using the therapeutic grade ionization chamber and thermoluminescence measurement method . The relationship between the measurement result by using ionization chamber dosimeter and the distances away from source was analyzed. The cumulative doses from a certain amount of pulsed radiation at the same location at different frequencies were compared.Results:In working condition, 100 pulses of radiation were received accumulatively at 1 to 12 meters away from the outer wall of the equipment. The range of air Kerma was 0.08-9.65 mGy measured by using thermoluminescence dometers and 0.08 - 9.85 mGy using the ionization chamber dosimeters, respectively. The difference between both is within 10%. At different frequencies (1-10 Hz), there was no significant difference in X-ray air Kerma from 100 pulses measured by ionization chamber dosimeter at 2 m away from the front of the equipment ( P>0.05). Conclusions:The therapeutic grade ionization chamber dosimeter can be used for the rapid measurement of short pulsed X-ray radiation dose in the range of dose rates and pulse frequencies involved in the experimental accelerator device.

ABSTRACT

Objective:To explore the relationship between the type of mutation and clinical features, prognosis, and clinical characteristics of chronic granulomatous disease (CGD) caused by compound heterozygous mutations in the NCF2 gene in children. Methods:The clinical data of 1 case of neonatal CGD caused by compound heterozygous mutations of NCF2 gene at Tianjin Children′s Hospital in August 2019 was analyzed, and domestic and international literatures were searched to summarize the clinical characteristics, gene mutation type and prognosis of CGD caused by NCF2 mutation. Results:The diagnosis of CGD was confirmed by the presence of compound heterozygous mutations c. 196_197insA (p.Arg66Glnfs23X) and c. 1180T>G (p.Tyr394Asp) in the NCF2 gene, accompanied with the clinical manifestations of fever, cough, multiple clumps and nodules in the chest CT at 25 days after birth, and the neutrophil respiratory burst test stimulation index(SI) 23.This new mutation was not reported in the Human Genetic Mutation Database.The child had a residual portion of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity and was followed up until the age of 9 months with an antifungal drug without recurrent infection.A total of 101 cases of CGD patients with NCF2 gene mutation were reported in domestic and international databases.Totally, 33 cases had SI results, with 22 cases below 3, 11 cases above 3, and 8 cases of missense mutations. Conclusions:c. 196_197insA and c. 1180T>G are new mutations in NCF2 gene that can lead to CGD.CGD patients containing missense mutations in the NCF2 gene may have more residual NADPH oxidase activity.

ABSTRACT

To investigate the value of contrast-enhanced ultrasound(CEUS)quantitative parameters in the diagnosis of thyroid benign and malignant nodules. The CEUS features of 85 histopathologically confirmed thyroid nodules were quantitatively analyzed using five parameters including rising time(RT),time to peak(TTP),area under the curve(AUC),maximum intensity(Imax),and mean transit time(mTT).The dynamic vascular pattern(DVP)curves were also drawn. The Imax(=-7.08,=0.01)and AUC(=-2.03,=0.04)of thyroid malignant nodules were significantly smaller than those of thyroid tissue,and the Imax(=-1.35,=0.02)and AUC(=-0.21,=0.02)of thyroid benign nodules were significantly larger than those of thyroid tissue.There were significant differences between thyroid benign and malignant nodules in Imax(=-4.16,=0.00),AUC(=-3.01,=0.01),and DVP curve types(=0.00).RT(=-0.28,=0.62),TTP(=-0.10,=0.89),and mTT(=-0.79,=0.05)were not significantly different between thyroid benign and malignant nodules. The quantitative parameters of CEUS,especially Imax and AUC parameters,are valuable in the diagnosis of benign and malignant thyroid nodules.

ABSTRACT

One hundred and ninety-three type 2 diabetic patients of average age of 70.3 years (96 males and 97 females), receiving insulin treatment at Diabetes Clinic of Caoyang Subdistrict Community Health Service Center from April to October 2018 were enrolled in the study. During the first visit, the average times of insulin injection pen needle use in the past month and the reason for repeated use were investigated; and the patients were informed that under the medical insurance policy in Shanghai, the reimbursement rate of the needles was increased to 80%. The patients were regularly instructed on the use of insulin needles in the follow-up visits. After 5 months the times of each insulin needle use were surveyed again. The first survey showed that 97.5% (188/193) of patients reused insulin needles, and each needle was used for (11.8±9.8) times; while the second survey showed that each needle was used for (4.4±4.4) times. Binary logistic regression analysis showed that the reuse behavior was affected by the frequency of education given by medical staff and the patient′s perception on expensiveness of the needles. It is suggested that clinical health education and fully informing medical insurance policy is important for the behavior change of reusing insulin injection pen needles in diabetic patients.

ABSTRACT

Objective: To observe the inhibitory effect of astragalus polysaccharides (APS) on growth of human breast cancer MDA-MB-231 xenograft tumor in nude mice and its effect on the apoptosis of tumor cells, in order to study the effect of APS on growth and induction of apoptosis of triple negative breast cancer MDA-MB-231 and its possible molecular mechanism. Method: Human breast cancer cell MDA-MB-231 was inoculated into the right axillary subcutaneous of BALB/c-nu female nude mice to establish the transplanted tumor model of breast cancer. Eighteen nude mice were randomly divided into 3 groups:model group (saline per day), low-dose APS group (200 mg·kg-1 APS per day), and high-dose APS group (400 mg·kg-1 APS per day), with 6 rats in each group. The drug was administered by gavage (200 μL) daily for 21 days. In the experiment, the length and diameter of breast cancer transplanted tumor were measured every two days, and the tumor volume was recorded and calculated. At the end of the experiment, the changes of tumor mass and tumor volume of the low and high-dose APS groups and the model group were observed and compared, and the tumor inhibition rate was calculated. The cell morphology in tumor tissue was observed by hematoxylin-eosin (HE) staining, and Terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) was used to verify the apoptosis of breast cancer tissues. The expressions of apoptosis-related proteins, such as B-cell lymphoma/leukemia-2 protein (Bcl-2), Bcl-2 associated X protein (Bax), Caspase in tumor tissues was detected by Western blot. Result: The tumor volume of breast cancer decreased in the low and high-dose APS groups, and the tumor inhibition rates were 37.9%and 57.57%, respectively, with statistically significant differences from the model group (PP0.01). HE of tumor tissue cells showed that APS led to obvious morphological changes, with apoptosis in the tissue cells. TUNEL staining showed that the apoptosis rate of tumor cells in APS intervention groups was higher than that in control group. Western blot showed that expression of Bcl-2 protein decreased(PPPPConclusion: APS can effectively inhibit the growth of MDA-MB-231 breast cancer xenografts in nude mice and induce apoptosis in human breast cancer MDA-MB-231 cells. The mechanism may be related to the effect of APS on expressions of apoptosis-related proteins Bcl-2, Bax, Caspase-9 and Caspase-7 in breast cancer cells.

ABSTRACT

Spinal α-motoneurons directly innervate skeletal muscles and function as the final common path for movement and behavior. The processes that determine the excitability of motoneurons are critical for the execution of motor behavior. In fact, it has been noted that spinal motoneurons receive various neuromodulatory inputs, especially monoaminergic one. However, the roles of histamine and hypothalamic histaminergic innervation on spinal motoneurons and the underlying ionic mechanisms are still largely unknown. In the present study, by using the method of intracellular recording on rat spinal slices, we found that activation of either H or H receptor potentiated repetitive firing behavior and increased the excitability of spinal α-motoneurons. Both of blockage of K channels and activation of Na-Ca exchangers were involved in the H receptor-mediated excitation on spinal motoneurons, whereas the hyperpolarization-activated cyclic nucleotide-gated (HCN) channels were responsible for the H receptor-mediated excitation. The results suggest that, through switching functional status of ion channels and exchangers coupled to histamine receptors, histamine effectively biases the excitability of the spinal α-motoneurons. In this way, the hypothalamospinal histaminergic innervation may directly modulate final motor outputs and actively regulate spinal motor reflexes and motor execution.

ABSTRACT

BACKGROUND: Immune eye diseases such as hyperthyroidism exophthalmos and uveitis seriously endanger the eye health of patients, which are common and difficult eye diseases. Current treatments for these diseases include oral administration of hormones and immunosuppressive agents, with poor efficacy, recurrent attacks and poor prognosis. Meanwhile, these treatments can induce systemic adverse reactions. Lymphocytes are directly or indirectly involved in these diseases. Therefore, we try to make papua eye patch carrying immunosuppressant, and deliver the drug through the topical use. Cyclosporin A microemulsion targeting lymphocytes can treat or control palpebral lymph nodes involved in the immune eye diseases. It is a topical method rather than the systemic medication, which is targeted and has small doses of drugs. If possible, this treatment can effectively treat immune eye diseases and avoid systemic drug adverse reactions and long-term adverse reactions induced by original drugs. OBJECTIVE: To study the preparation of cyclosporin A microemulsion papua cream eye patch, and its transdermal absorption characteristics in vitro. METHODS: Cyclosporine A microemulsion was fully mixed with water-soluble polymer materials at a ratio of 1 mg:1 mL, including sodium polyacrylate, polyvinyl alcohol, polyvinylpyrrolidone, gelatin, peach gum, sodium carboxymethylcellulose, hydroxypropylcellulose, and then coated onto the non-woven fabric to prepare Babu cream. Permeability of the Babu cream on the abdominal skin of ICR mice was determined by Franz diffusion cell method. High-performance liquid chromatography was used to detect the concentration of cyclosporine A, and skin irritation and anaphylaxis were also measured. RESULTS AND CONCLUSION: Cyclosporin A microemulsion papua cream eye patch was successfully prepared with appropriate viscosity, good permeability, good permeability, comfortable application, no skin irritation and allergic reaction. The content of cyclosporine A was 10 mg/tablet, and the concentration was 1 g/L. The concentration of cyclosporine A microemulsion increased with the increase of time, and it had good transdermal effect. This study proved that it is feasible to prepare cyclosporine A microemulsion into papua patch. It has good performance in skin permeability, adhesion and skin comfort.

ABSTRACT

Human cytosolic sulfotransferase 2A1 (SULT2A1) is an important phase II metabolic enzyme. The detection of SULT2A1 is helpful for the functional characterization of SULT2A1 and diagnosis of its related diseases. However, due to the overlapping substrate specificity among members of the sulfotransferase family, it is difficult to develop a probe substrate for selective detection of SULT2A1. In the present study, through characterization of the sulfation of series of bufadienolides, arenobufagin (AB) was proved as a potential probe substrate for SULT2A1 with high sensitivity and specificity. Subsequently, the sulfation of AB was characterized by experimental and molecular docking studies. The sulfate-conjugated metabolite was identified as AB-3-sulfate. The sulfation of AB displayed a high selectivity for SULT2A1 which was confirmed by reaction phenotyping assays. The sulfation of AB by human liver cytosols and recombinant SULT2A1 both obeyed Michaelis-Menten kinetics, with similar kinetic parameters. Molecular docking was performed to understand the interaction between AB and SULT2A1, in which the lack of interaction with Met-137 and Tyr-238 of SULT2A1 made it possible to eliminate substrate inhibition of AB sulfation. Finally, the probe was successfully used to determine the activity of SULT2A1 and its isoenzymes in tissue preparations of human and laboratory animals.

ABSTRACT

The ventral pallidum (VP) is a crucial component of the limbic loop of the basal ganglia and participates in the regulation of reward, motivation, and emotion. Although the VP receives afferent inputs from the central histaminergic system, little is known about the effect of histamine on the VP and the underlying receptor mechanism. Here, we showed that histamine, a hypothalamic-derived neuromodulator, directly depolarized and excited the GABAergic VP neurons which comprise a major cell type in the VP and are responsible for encoding cues of incentive salience and reward hedonics. Both postsynaptic histamine H1 and H2 receptors were found to be expressed in the GABAergic VP neurons and co-mediate the excitatory effect of histamine. These results suggested that the central histaminergic system may actively participate in VP-mediated motivational and emotional behaviors via direct modulation of the GABAergic VP neurons. Our findings also have implications for the role of histamine and the central histaminergic system in psychiatric disorders.

ABSTRACT

Cytochrome P4502J2 (CYP2J2) is widely distributed in various human tissues and takes a part in the metabolism of endogenous compounds and drugs. CYP2J2 can convert arachidonic acid (AA) to expoxyeicosatrienoic acids (EETs), which have various biological effects, implying the important role of CYP2J2 in the regulation of cardiovascular system and promotion of tumor progression and metastasis. Additionally, CYP2J2 plays an indispensable role in the intestinal metabolism of various drugs, such as astemizole, terfenadine and ebastine. In this review, the metabolic function, characteristic of catalysis and tissue distribution of CYP2J2 are discussed with the latest literatures both in China and abroad. The state-of-the-art methods for characterization of CYP2J2 and current trend of substrate discovery as well as its relationship with disease are highlighted. This review gives in-depth understanding of the function of CYP2J2 and its role in disease advance. The information of ligand (substrate and inhibitor) will provide the theoretical guidance and reference to the development of novel drugs for CYP2J2.

ABSTRACT

The subthalamic nucleus (STN) is the only excitatory glutamatergic nucleus in the basal ganglia circuitry. It not only is a key node in the classical indirect pathway, but also forms the "hyperdirect" pathway directly connecting the cortex, and even is implicated as a pacemaker for activity of whole basal ganglia. Due to the key position of STN in the basal ganglia circuitry, the STN is an optimal target for deep brain stimulation (DBS) in the neurosurgical treatment of Parkinson's disease (PD). However, the therapeutic mechanisms underlying the amelioration of parkinsonian motor dysfunctions induced by DBS on STN remain enigmatic. This paper reviews recent progresses in the studies on the input-output configurations and functions of STN in the basal ganglia circuitry, and summarizes the hypotheses for mechanisms of DBS for the treatment of motor dysfunctions in PD. Studying on the DBS mechanisms will not only help to develop strategies for treatment of PD, but also contribute to the understanding of functions of the basal ganglia circuitry.

ABSTRACT

Pertussis infection can mimick the clinical manifestations of lower airway infection, while the symptoms and signs in some cases are like Bronchiolitis. The paper carried out retrospective analysis of infant pertussis bordetella infected cases admitted by the Respiratory Dept. of Tianjin Children's Hospital for "capillary bronchitis" from Sept. 2015 to Feb. 2016. It analyzed its clinical features, radiological features, laboratory characteristics and outcome through comparing the capillary bronchitis cases induced by the non-bordetella pertussis. 26 cases of patients infected with bordetella pertussis were included in the group, 15 male patients and 11 female patients, aging from 40 days to 11 months. Comparing with non-pertussis infected cases, the capillary bronchitis induced by pertussis presents spasmodic cough, vomiting after cough, apnea suspension and lymphocythemia and obvious prolong of LOS. However the clinical symptom score is decreased and the duration of breathing is shorter. The follow-up visit detects that the recurrent number of respiratory symptoms of pertussis infected children is higher than that of non-pertussis infected children. The clinical symptoms of patients with capillary bronchitis infected by bordetella pertussis are not typical and are susceptible to be ignored. The duration of respiratory symptoms is longer and susceptible for recurrence
