Objective To investigate the expression of JMJD3 and its functions for cell growth in human gastric carcinoma.Methods The expression of JMJD3 was detected by immunohistochemistry.Recombinant JMJD3 plasmids were transfected into MGC-803 cells.Cell proliferation was determined by CCK-8 assay and cell apoptosis was detected by flow cytometry.Results The expression of JMJD3 was down-regulated in gastric carcinoma tissues (P ＜ 0.05).Low expression of JMJD3 was associated with advanced TNM stage (Ⅲ+Ⅳ,P ＜ 0.05).Overexpression of JMJD3 could inhibit cell proliferation and induce cell apoptosis (P ＜ 0.05).Conclusion Low expression of JMJD3 was commonly existed in gastric cancer.JMJD3 could inhibit cell proliferation and induce cell apoptosis.

Objective To explore the expression of P53 and mettl-9 gene in colon cancer tissues and inflammation tissues and normal adjacent tissues and study its relationship with colon cancer.Methods The morphologic situation of histiocyte after H.E.stained was observed.The real-time fluorescent quantitative PCR was applied to detect the gene expression of P53 and METFL-9.Results The expression of P53 gene in inflammation tissues was significantly higher than that in cancer tissues and adjacent tissues(P ＜0.05).The expression of P53 gene in cancer tissues was significantly lower than adjacent tissues and infiammation tissues.METTL-9 gene expression in inflammation tissues was significantly lower than cancer tissues and adjacent tissues(P ＜0.05).In cancer tissues,P53 gene and METFL-9 gene were negative related.Conclusions The mutations of P53 gene played an important role in the course of colon cancer,its downstream gene METTL-9 was highly expressed in colon cancer,and the 9-methyl-converting enzyme which produced by transcription and translation might lead gene hypermethylation in the colon cancer,and thereby promoted the development of colon cancer.

ObjectiveTo investigate the effect of acupuncture on motor function and serum expressions of TNF-aand IL-6 contents in cerebral hemorrhage rats.MethodSeventy-two male Wistar rats were randomized into sham operation, model and acupuncture groups. A rat model of cerebral hemorrhage was made by intracerebral injection of autoblood. Baihui-to-Qubin acupuncture was performed after successful model making. The TNF-aand IL-6 contents of rat serum were measured by enzyme linked immunosorbent assay at three time points: one, three and seven days.ResultBaihui-to-Qubin acupuncture markedly increased the neurological function score and reduced neurologic deficits in cerebral hemorrhage rats. At the same time point, serum TNF-aand IL-6 contents were significantly lower in the acupuncture group of rats thanin the model and acupuncture group; there were statistically significant differences (P<0.01).ConclusionBaihui-to-Qubin acupuncture can reduce neurologic deficits in cerebral hemorrhage rats. It may be related to decreases in serum TNF-aand IL-6 contents after acupuncture.

Purpose To compare the CT features of hepatic angiomyolipoma (HAML) and primary hepatocellular carcinoma (HCC) and improve diagnostic accuracy for HAML. Materials and Methods The CT findings of 9 patients with HAML confirmed pathologically and 20 patients with HCC were retrospectively analyzed in terms of lesion location, appearance, size, margin, CT value at each phase, cirrhosis and vessel presence inside tumor. Results Mean CT value on plain scan and at arterial phase on contrast enhanced scan of HAML was significantly lower than that of HCC (t=-2.885, P<0.05;t=-3.307, P<0.01). At portal vein phase, difference in CT value showed no statistic significance (t=-0.293, P>0.05). CT value on plain scan and at arterial phase of both HAML and HCC was not significantly different (t=1.289, P>0.05) whilst that at portal vein phase was significantly different (t=2.516, P<0.05). Central vessels were shown in 7 cases of HAML and 3 cases of HCC, pseudocapsule appeared in 1 case of HAML and 13 cases of HCC with statistical difference (χ2=10.828, 7.219;P<0.01). Conclusion CT scan of HAML reveals the component of fat and presentsfast in and slow outpattern, large shadow of vessel and absence of capsule on contrast enhanced scan, which can be helpful in the differential diagnosis from HCCs.

Objective To establish nucleic acid testing techniques for detecting Nipah virus (NiV) and Hendra virus (HeV), and to test the NiV and HeV in peripheral blood collected from domestic pigs, cows and goats in Chongqing. Methods Peripheral blood samples of 580 domestic pigs, 250 cows, 180 goats were collected from Chongqing since June 2007 to June 2008. The lymphocytes were separated by density gradient centrifugation and total RNA was extracted using Trizol method for detection of NiV and HeV with one-step real-time RT-PCR. Sequence identification and analysis were performed for positive PCR prod-ucts. Virus isolation and culture were adopted for positive samples, and epidemiologic reports were submit-ted. Results Nucleic acid detections searching for NiV and HeV were successfully performed in animal blood samples collected from Chongqing. "Takeoff points" were not found in fluorescence amplification curves of all samples. Curves kept the same slope, and assays were judged as negative. Conclusion Until now, Neither NiV or HeV infection has been found in domestic animals blood samples collected from Chongqing, which suggest a lower possibility of outbreaks of Nipah disease and Hendra disease in Chongqing in the near future.

Objective To discuss the clinical values of two-dimensional and three-dimensional diagnoses of nontraumatic esophageal hiatal hernia (HH) in middle-aged and elderly people. Methods Thirty-two cases underwent two-dimensional and three-dimensional ultrasonic examination with fasting and water iflling methods in half-sitting, standing, supine and supine right anterior oblique positions. The ifndings were compared with X-ray barium meal examination, endoscopy and operation. Results There were 27 cases sliding HH, 3 cases paraesophageal HH and 2 cases short HH. Traditional two-dimensional manifestations were as follows:widening of hiatal diaphragmatic muscles (1.6±0.4 cm) and echoes of gastric mucosa in superior hernial sac and inside hernial sac. Real-time three-dimensional surface image formations were as follows: along the long axis of diaphragmatic hiatus, superior phrenic sac was showed as mushroom-shaped or pond-shaped and the neck of hernial sac was showed as irregular tunnel-shaped or ditch-shaped;looking upward from the fundus of stomach, superior phrenic hiatus was showed as caved-shaped or louver-shaped;looking downward from mediastinal surface of lung, uperior phrenic hiatus was showed as piercer-shaped. Conclusions Two-dimensional abdominal ultrasound can diagnose nontraumatic HH in middle-aged and elderly people conveniently and accurately. Real-time three-dimensional abdominal ultrasound can display the range, size, and shape clearly. Compared with the former, the latter can provide more information for diagnosis and help ultrsound doctors and clinical doctors to understand and master the anatomical and morphopathological features of this disease.

After surgery vascular crisis directly affects the success rate of the flap transplantation, hence method of monitoring the after surgery microcirculation has been developed as a medical practice. However, clinical application of postoperative monitoring of microcirculation is still in debate. In particular, the invasive monitoring techniques are not systematically reported in China. The purpose of this review is to summarize the advantages and disadvantages of the postoperative monitoring of microcirculation and to provide reference for staffs in microsurgery.

Objective To investigate the epidemiology of BDV infection in Yili horses and Yili donkeys and to analyze phylogenetic source of BDV in Yili area, Xinjiang. Methods We established fluo- rescence quantitative nested RT-PCR to detect BDV p24 segment in peripheral blood mononuclear cells (PBMCs) of 518 Yili horses and 206 Yili donkeys in Yili area, Xinjiang. Positive products were validated by detecting BDV p40 segment and plasmid to preclude the contamination, and were sequenced to analyze the homology of gene sequence, amino acid sequence and phylogenetic tree. Results The positive rates of BDV infection in PBMCs of 518 Yili horses and 206 Yili donkeys were 0.97% and 1.94%, respectively. The results of BDV p40 segment verification were positive in all of the samples of BDV p24 positive. All the samples tested were not contaminated by plasmid. There was a homology of the gene sequence of positive PCR samples with strain He/80. And the gene sequence revealed more than 93% identical to H1766 and strain V. Conclusion Our study suggested BDV natural infection in Yili horses and Yili donkeys. The en- demic BDV had a high degree of identity to strain He/80.

Objective To observe the effects of penetrance,different time of onset and mutation sites on retinal nerve fiber layer (RNFL) and macular thickness in patients with Leber's hereditary optic neuropathy (LHON).Methods This was a cross-sectional observational study.A total of 88 patients with LHON and 1492 relatives of the maternal relatives (gene carriers) who received treatment in People's Liberation Army General Hospital from 2015 to 2017 were included in the study.Among the 1492 family members,there were 694 males and 798 females.Peripheral venous blood was extracted from all subjects for mitochondrial DNA testing,and penetrance was calculated.A total of 117 patients underwent BCVA and SD-OCT examinations,including 82 patients and 35 gene carriers.The BCVA examination was performed using the Snellen visual acuity chart,which was converted into logMAR visual acuity.The thickness of RNFL,ganglion cell complex (GCC) and inner limiting membrane (ILM)-RPE were measured with OCT instrument.The mean follow-up was 50.02± 86.27 months.The disease course was divided into 6 stages including ≤3 months,4-6 months,7-12 months and ＞ 12 months.The thickness of RNFL,GCC and ILM-RPE in patients with different time of onset and mutation sites were comparatively analyzed by covariance analysis.Categorical variables were expressed as a percentage,and the x2 test was used for comparison among multiple groups.Results Among the 1492 family members,285 were diagnosed with LHON and highly suspected clinical manifestations (19.10％),including 190 males (21.98％) and 95 females (11.90％).The total penetrance rates of 11778,14484 and rare mutation sites were 19.84％ (228/1149),20.50％ (33/161),and 13.19％ (24/182) respectively;male penetrance rates were 28.87％ (153/530),27.28％ (20/72),and 18.48％ (17/92) and female penetrance rates were 12.12％ (75/619),14.61％ (13/89) and 7.78％ (7/90).There was no significant difference in total (x2=4.732),male (x2=4.263) and female (x2=4.263) penetrance between different mutation sites (P=0.094,0.110,0.349).Compared with non-pathogenic carriers,the thickness of the RNFL,GCC and ILM-RPE were all different in the four stages (≤3months,4-6 months,7-12 months and ＞12 months).The thickness ofRNFL,GCC and ILM-RPE decreased with the time of onset (P=0.000).There were significant differences in the thickness of each of the GCC and ILM-RPE layers in the macular area of LHON patients with different mutation sites (P＜ 0.05).Among them,the site 11778 and 3460 had the most severe damage in all quadrants of macular GCC and ILM-RPE layer,followed by 14484 site,and the rare site had the least damage in all quadrants.Conclusions The penetrance of LHON patients is 19.10％.With the extension of the onset time (within 1 year),the RNFL layer of the optic disc and all quadrants of the macular GCC and ILM-RPE layer gradually thinned.Compared with 11778 and rare site,14484 site,and the rare site had the lighter damage on the thickness of RNFL,GCC and ILM-RPE.
