In our previous work, we found that trivalent dimethylarsinous acid (DMA(III)) have high affinity binding to cysteine residue 13 of rat hemoglobin. However, it is still unknown why arsenic intermediate metabolite DMA(III) has high binding affinity for Cysl3 but not for other cysteine residues 93, 140, 111 and 125. In order to better understand the molecular mechanism of DMA(III) with rat hemoglobin, we have done current study. So, SD rats were divided into control and arsenic-treated groups randomly. Arsenic species in lysate of red blood cells were analyzed by HPLC-ICP-MS, and then determined by a hybrid quadrupole TOF MS. In addition, trivalent DMA(III) binds to different cysteine residues in rat hemoglobin alpha and beta chains were also simulated by Molecular Docking. Only Cys13 in alpha chain is able to bind to DMA(III) from the experiment results. Cys13 of alpha chain in rat hemoglobin is a specific binding site for DMA(III), and we found that amino acids compose pockets structure and surround Cys13 (but not other cysteine residues), make DMA(III) much easy to bind cysteine 13. Taken together, the DMA(III) specific binding to Cys13 is related to spatial structure of Cys13.

OBJECTIVETo study the effect of Guishen Pill (GSP) on expression levels of Oct-4, MVH, and Egr-1 in mice with diminished ovarian reserve (DOR).

METHODSTotally 40 female C57BL/6J mice were randomly divided into 4 groups, the normal control group, the model group, the GSP group, and the dehydroepiandrosterone (DHEA) group, 10 in each group. Pregnant mare serum gonadotropin (PMSG), human chorionic gonadotropin (HCG), and prostaglandin F2α (PGF2α) were sequentially administrated to produce superovulation. The DOR model was established by exposing to ozone inhalation. Mice in the GSP group were intragastrically administered with GSP at 0.3 mL. Those in the DHEA group were intragastrically administered with DHEA at 0.3 mL. Equal volume of normal saline was intragastrically administered to mice in the normal control group and the model group. All mice wer treated for 21 days. Serum levels of estrogen (E2), progestogen (P), and anti-Müllerian hormone (AMH) were measured by ELISA. Changes of Oct-4, anti-AMH, and early growth response gene-1 (Egr-1) mRNA in ovaries were dtected by Real-time PCR.

RESULTSCompared with the model group, serum levels of E2, P, and AMH, as well as contents of estrogen receptor (ER), progestogen receptor (PR), MVH, and Oct-4 mRNA significantly increased in the GSP group and the DHEA group (P < 0.05).

CONCLUSIONGSP could improve expression levels of Oct-4, MVH, and Egr-1 mRNA in DOR mice and their ovarian function.

OBJECTIVETo compare the effect of citric acid stimulation on salivary alpha-amylase (sAA), total protein (TP), salivary flow rate, and pH value between Pi deficiency (PD) children and healthy children, thereby providing evidence for Pi controlling saliva theory.

METHODSTwenty PD children were recruited, and 29 healthy children were also recruited at the same time. Saliva samples from all subjects were collected before and after citric acid stimulation. The sAA activity and amount, TP contents, salivary flow rate, and pH value were determined and compared.

RESULTS(1) Citric acid stimulation was able to significantly increase salivary flow rate, pH value, sAA activities, sAA specific activity and sAA amount (including glycosylated and non-glycosylated sAA amount) in healthy children (P<0.05), while it could markedly increase salivary flow rate, pH value, and glycosylated sAA levels in PD children (P<0.05); (2) Although there was no statistical difference in determined salivary indices between the two groups (P>0.05), salivary indices except salivary flow rate and glycosylated sAA levels decreased more in PD children. There was statistical difference in sAA activity ratio, sAA specific activity ratio, and the ratio of glycosylated sAA levels between PD children and healthy children (P<0.05).

CONCLUSIONPD children had decreased response to citric acid stimulation.

This study attempts to discuss the correlation between UGT1A1*28 as uridine diphosphate glucuronosyltransferase gene promoter and coding region Gly71Arg gene polymorphism with neonatal hyperbilirubinemia of neonates in Wuhan.A total of 168 neonates were divided into the hyperbilirubinemia group (case group,n=108) and healthy neonates group (control group,n=60).Their DNA was obtained through blood extraction.The gene exon mutation of UGT1A1 was detected by Sanger sequencing,which revealed the relationship between UGT 1A 1*28 and Gly71Arg polymorphism with neonatal hyperbilirubinemia of neonates.The results showed that:(1) The frequency of UGT1Al*28 allele mutation in the case group and the control group was 9.3％ and 10％ respectively,with the difference being not significant between the two groups (P＞0.05).(2) The frequency of Gly71Arg allele mutation in the case group and the control group was 35.1％ and 21.7％ respectively,with the difference being significant between the two groups (P＜0.01).(3) The serum bilirubin level of Gly71Arg mutant homozygous and heterozygous subgroups (n=66) in the case group was 302.7±31.4 μmol/L,which was significantly higher than 267.3±28.5 μmol/L of the wild subgroup (n=42) (P＜0.01).It was suggested that the occurrence of neonatal hyperbilirubinemia of neonates in Wuhan was not associated with UGT 1A1*28 gene polymorphism,but closely with the Gly71Arg gene polymorphism.Meanwhile,the Arg allele mutation was related to the degree of jaundice.

The study was to investigate the role of homocysteine (Hcy) which was released by hippocampal glial cells and its relationship with NMDA receptor and AMPA receptor in depression induced by chronic unpredictable mild stress (CUMS), and explore the mechanism of changes of Glu/Glu receptor in glial cells and neurons. CUMS-induced depression model was established. The body weight of rats was weighed on the 1st, 7th, 14th, and 21st days during the experiment. The behavioral performances were observed by means of sucrose consumption test, open field test and tail suspension test. Intrahippocampal microinjection of Hcy, NMDA receptor antagonist MK-801 and AMPA receptor antagonist NBQX was performed under stereotaxic guide cannula. The concentration of Glu and the expression of its receptors' subunits were detected respectively by high performance liquid chromatography (HPLC) and Western blot. The Hcy content and the levels of phosphorylation of NMDA receptor and AMPA receptor in hippocampus were separately determined by enzyme linked immunosorbent assay (ELISA). The results showed that CUMS significantly induced the depression-like behaviors in rats, and the content of Glu and Hcy, the expression of NMDA receptors' subunits NR1/NR2B and the level of phosphorylation of NMDA receptor (p-NMDAR) in hippocampus increased significantly, while the expression of AMPA receptors' subunits GluR2/3 and the level of phosphorylation of AMPA receptor (p-AMPAR) decreased significantly. Microinjection of Hcy into hippocampus resulted in similar animal depression-like behaviors and increased Glu content compared to the CON/SAL group, the expression of NR1/NR2B/GluR2/3 and the level of p-NMDAR increased significantly, but the level of p-AMPAR reduced observably. Intrahippocampal injections of MK-801 effectively improved the depression-like behaviors induced by CUMS and Hcy, and attenuated the elevation of Glu content induced by Hcy in hippocampus, whereas NBQX could not improve the depression-like behaviors, but also decreased the Glu content induced by Hcy remarkably. These results suggest that CUMS may contribute to the production and release of Hcy via hippocampal astrocytes. Through the increase of expression of NR1/NR2B/GluR2/3 and level of p-NMDAR, and the decrease of level of p-AMPAR, Hcy results in elevation of Glu level, which leads to depression-like behaviors in the end. In a word, the Hcy released by astrocytes plays an important role in stress-induced elevation of Glu content and variation of NMDA/AMPA receptors in hippocampus.

Periventricular white matter damage is one of the characteristics of brain damage in preterm infants, and it is the most important type of encephalopathy. The pathological changes including the white matter of coagulation necrosis, oligodendrocyte damage, myelin damage, axonal injury and reactive gliosis and microglia infiltration in necrotic areas. All of these lesions are closely related to the nervous system sequelae in later-neonatal period. The pathogenesis of periventricular leukomalacia in premature infants are mainly cause by its immature brain vascular, and precursor oligodendrocytes of the attack of hypoxia, ischemia, infection, oxygen free radicals, inflammatory cytokines, increasing glutamate, and other high-risk factors. In this paper, an overview of progress in the study of the pathogenesis of periventricular white matter damage in premature infants through literature review to provide a theoretical support for clinical prevention, diagnosis and treatment.

OBJECTIVEThe clinical effect of the Shi's cervical reduction technique for cervical spondylosis and related disorders has confirmed, however, there were few studies on the body motion during manipulation in vivo study. This study is to summary the law of motion and the motion characteristics of the right operation shoulder, elbow, knee and ankle joints by data acquisition and analysis with the 3D motion capture system.

METHODSThe markers were pasted on the head, trunk, left and right acromion, elbow joint, wrist joint inner side and the outer side of the inner and the outer side and the lateral upper arm, forearm lateral, anterior superior iliac spine, posterior superior iliac spine, trochanter, femoral and tibial tubercle, inner and outer side of knee, ankle, fibular head, medial and lateral in first, 2,5 metatarsal head, heel and dual lateral thigh the calf, lateral tibia of one manipulation practioner, and the subject accepted a complete cycle of cervical "Jin Chu Cao and Gu Cuo Feng" manipulation which was repeated five times. The movement trajectory of the practioner's four markers of operation joints were captured, recorded, calculated and analyzed.

RESULTSThe movement trajectories of four joints were consistent, while the elbow joint had the biggest discrete degree. The 3D activities of the shoulder and elbow were more obvious than other two joints, but the degree of flexion and extension in the knee was significantly greater than the rotation and lateral bending.

CONCLUSIONThe flexibility of upper limb joint and stability of lower limb joint are the important guarantees for the Shi's cervical reduction technique, and the right knee facilitated the exerting force of upper limb by the flexion and extension activities. The 3D model built by the motion capture system would provide a new idea for manipulation teaching and further basic biomechanical research.
