ABSTRACT
Objective:To investigate the value of serum programmed cell death molecule 5 (PDCD5) protein expression in early prediction of gastric cancer and its clinical significance.Methods:A total of 103 patients with gastric cancer who were treated in Yuechi County People′s Hospital in Sichuan Province from March 2014 to March 2016 and 80 healthy people who underwent physical examinations (control group) in the same period were selected as subjects. The serum level of PDCD5 protein were detected by enzyme-linked immunosorbent assay. The diagnostic performance of serum PDCD5 protein on gastric cancer was evaluated by receiver operating characteristic curve. The patients with gastric cancer were divided into low-level group (50 cases) and high-level group (53 cases) according to serum PDCD5 protein level. The relationship between serum PDCD5 protein level and clinical data in patients with gastric cancer was analyzed by χ2 test. Univariate and multivariate Cox regression models were used to analyze independent risk factors for survival and prognosis of gastric cancer. Kaplan-Meier method was used to map survival curves of gastric cancer patients with different levels of serum PDCD5 protein. Results:Serum PDCD5 protein level in gastric cancer group was significantly lower than that in control group: (0.82 ± 0.30) mg/L vs. (1.26 ± 0.39) mg/L, and there was statistical difference ( t=8.628, P<0.01). Serum PDCD5 protein level in patients with gastric cancer was related to tumor TNM stage and tumor invasion ( P<0.05), but not related to gender, age, body mass index (BMI), tumor size, lymph node metastasis, tumor type and tumor differentiation ( P<0.05). The area under curve (AUC) of serum PDCD5 protein in the diagnosis of gastric cancer was 0.810 (95% CI 0.747 to 0.873), with a sensitivity of 71.8%, and a specificity of 76.3% ( Z=9.641, P<0.01). Serum PDCD5 protein level was an independent risk factor for poor prognosis in patients with gastric cancer ( P<0.05). The 5-year survival rate in low-level group was significantly lower than that in high-level group: 32.0% vs. 62.3%, and there was statistical difference ( χ2=18.422, P<0.01). Conclusions:The serum PDCD5 protein level in patients with gastric cancer is significantly decreased. Low serum PDCD5 protein level is independent risk factors for poor prognosis of patients with gastric cancer.
ABSTRACT
Objective The purpose of this study was to assess the value of prenatal ultrasound diagnosis for fetal ear auricle malformations.Methods The coronal and sagittal planes of fetuses ears were obtained prospectively in 6239 singleton fetuses in the First Affiliated Hospital of Shantou University Medical College for the period from 2012 February to 2015 December,the ultrasound images and pregnancy outcomes were analyzed in 11 cases of fetuses ear auricle malformations diagnosed prenatally.Results Eleven Cases of fetuses ear auricle malformations include with 7 cases of microtia,3 cases of low-set ears and 1 case of anotia.Eleven cases were combined with other structural malformations were as followings,3cases with craniocerebral congenital malformation,5 cases with dentofacial deformity,5 cases with malformation of heart,3 cases with limb deformity.Cordocentesis was performed in 7 cases among which 6 with abnormal karyotype,including 2 cases of trisomy 21,2 cases of trisomy 13,2 cases of trisomy 18,1 case of 22ql 1 abnormalities.Compared with the postpartum facial examination,prenatal ultrasound correctly diagnosed 10 cases of fetal ear auricle malformations,missed diagnosis 1 case of microtia.Conlusions Fetus with ear auricle abnormalities have characteristic prenatal ultrasound imaging;prenatal ultrasonography can provide reliable information in the diagnosis of this disease.This study suggests that antenatal ear auricle length measurements might be a promising sonographic screening method for the detection of abnormal karyotype in pregnancy.
ABSTRACT
Objective To investigate auditory sensory gating potential in the siblings of schizophrenic, to discover the neuroimaging features of sensory gating associated with schizophrenia as intermediate phenotypes. Methods Twelve siblings of schizophrenia patients in the first episodic, and 12 healthy controls matched in gender, age, education under?went MRI scan when performing a auditory sensory gating fMRI task (repeated clicks and single click auditory stimuli). The measure of sensory gating was the contrast of repeated clicks minus single click. The analysis of result was imple?mented in SPM2. Results Compared with healthy controls, schizophrenia patients showed significant overactivation in the right inter cingulate gyrus (x=4,y=8,z=32) and left anterior cingulate gyrus (x=-8,y=4,z=28) during the fMRI senso?ry gating task. Conclusion Sensory gating is overactivated in the cingulate gyrus in siblings of schizophrenic. This pat?tern may be a potential endophenotype of schizophrenia.
ABSTRACT
Chondroitin sulfate (CS) is the typical sulfation glycosaminoglycan and widely applied in the industries of pharmaceutical, health products and cosmetic for its peculiar properties. CS is the main component of cartilage proteoglycans in animal and capsular polysaccharide in a few bacteria. CS can be extracted from animal sources and produced via microbial fermentation. In this article, development of chondroitin sulfate by fermentation, biosynthesis and regulating mechanisms of CS in bacteria are described. Furthermore, prospect and tendency of chondroitin sulfate from bacterial fermentation are addressed.

Objective To observe the characteristic of the functional magnetic resonance imaging (fMRI) brain map in health adult undergoing clenching and relaxing the fist, for exploring the essence of the fMRI brain map in patients suffering from motor dysfunction by cerebrovascular accidents. Methods Twelve healthy volunteers had been chosen to partake the experience. Everyone had accomplished the following three actions separately: (1) Only clenching and relaxing the fist of left hand. (2) Only clenching and relaxing the fist of right hand. (3) Clenching and relaxing the fist of both hands at one time. The data had been analyzed statistically using analysis of functional neuroimages (AFNI) software. Results Under condition of F (6,1121), P = 0.005. Only clenching and relaxing the fist of left hand had gained the following brain functional area: right precentral gyms, left parietal,right superior temporal gyrus,right parietal, right parahippocampal gyrus, right superior frontal gyrus, right medial frontal gyrus, left precuneus, right superior parietal lobule, right middle frontal gyrus, left superior frontal gyrus. Only clenching and relaxing the fist of right hand had gained the following brain functional area: left precentral gyms, left postcentral gyrus right parietal, right medial frontal gyrus. Clenching and relaxing the fist of beth hands simultaneously had gained the following brain functional area: left precentral gyms,left postcentral gyrus, right precentral gyrus, right postcentral gyrus. Conclusions Hand movement (clenching and relaxing the fist) has its own specific brain activated areas. The brain areas activated by clenching and relaxing the fist of both hands simultaneously concentrate in the motor area of both cerebral hemisphere. The brain areas activated by clenching and relaxing the fist of single hand contain not only the motor area, but also the supplementary motor area. As compared with the right handedness, the brain areas activated by clenching and relaxing the fist of left hand is more widespread.
