Acta Anatomica Sinica 1957;0(04):-
Connection between the superior colliculus(SC)and the dorsal and ventral lateral geniculate nuclei (LGd and LGv) were studied in adult golden hamsters using anterograde and retrograde pathway tracing methods 1. In four hamsters, the cytoarchitecture of the SC, LGd and LGv was examined in brain sections stained with Nissl's or Loyez's method. 2. A single injection of a mixture of ~3H-leucine and ~3H-proline was made into various regions of the SC in each of 4 animals (1 day survival) for studying the pattern of terminal distribution of the projections from the SC to the ipsilateral LGd and LGv. In animals where the injection site was located in the superficial gray layers of the lateral portion of the SC, labelled terminals were found in the caudal lateral part of the LGd and LGv. In the case where the injection was restricted in more medial part of the SC, the terminal labelling was observed in the rostral lateral portion of the lateral geniculate nuclei. 3. One day after an injection of horseradish peroxidase (HRP) into the LGd (4 animals), LGv(2 animals), or LP(2 animals) labelled neurons were observed in the superficial gray layers of the ipsilateral superior colliculus. No HRP-labelled neuron was detected in deeper laminae in the colliculus. These results indicate that neurons in the superficial gray layers of the SC project to the ipsilateral LGd and LGv, and the projections are organized topogra- phically according to the retinotopic or visual field map

Objective To detect 10 RNA viruses including Alphavirus in Togoviridae, Flavivirus in Flaviridae, Hantavirus and Nairovirus in Bunyavirudae and SARS-CoV in Coronavirudae by using genechip technique. Methods The universal PCR primers of Alphavirus and Flavivirus and the PCR primers specific for HFRSV in Hantavirus and XJHFV in Nairovirus were designed by DNAStar software. PCR primers specific for SARS-CoV were adopted from WHO website. In addition, all the PCR primers specific for each virus were designed inside the regions of universal primers. These specific primers were utilized for amplification of cDNA probes. The concentration of probes, the hybridization temperature and duration, the formulation of hybridization solution and the washing conditions were optimized. Results The specific hybridization signals could be obtained when the concentration of probes was 0.3?g/?l. Good hybridization signals could be obtained for all the 10 RNA viruses when the hybridization solution contained 20% formamide, and the hybridization reaction was conducted at 60℃ for 1.5 hours. Two or four pathogens could be detected simultaneously when the target nuclear acids were amplified by multiplex PCR. Conclusion The results showed that the virus pathogens could be detected by genechip technique, and the key step was to design suitable primers and probes.

Objective To explore the expression of the nuclear factor -κB (NF-κB) regulating monocyte ehemoactracttive peptide -1 ( MCP-1) in asthma patients, and investigate the effect of seretide, budesonide and vento-lin. Methods 81 asthma patients were randomly divided into seretide therapy group and budesonide and ventolin therapy group. The NF-κB activation in PBMC and the plasma concentrations of MCP-1 were measured by ELISA. ventolin therapy group (1.70±0.39) ng/L of asthma patients were significantly higher than that control group (0.89±0.34) ng/L ( P<0.001 ) ; The plasma MCP-1 level in seretide therapy group ( 66.89±5.62 ) ng/L and in budesonide and ventolin therapy group (73.35±7.52 ) ng/L of asthma patients were also significantly higher than level of seretide therapy group in asthma patients were significantly lower than budesonide and ventolin therapy group (P <0.001 ). Conclusion NF-κB gene and its regulating protein MCP-1 may be involved in asthma. Glucocotios-teroid and beta2 agonists combination may prolong the process of asthma.

Objective To investigate the clinical characteristics and the treatment of pancreatic encephalopathy (PE) and Wernicke's encephalopathy (WE). Method A retrospective study was conducted on 596 cases of acute pancreatitis. Results There were 93 cases of severe acute pancreatitis (SAP),among them encephalopathy was discovered in 10 patients (1.7%). All 6 patients of PE developed in SAP (6.5%);3 patients died (3% of SAP,50% of PE). Four cases of WE developed in AP (0.7%);2 patients died (0.3% of AP,50% of WE). Two patients of WE were treated with parenteral thiamine (vitamin B_ 1 ),and they survived. Conclusions PE occurred in early stage of SAP or recrudescence,while WE usually occurred in convalescent stage of SAP/AP. Long fasting,repeated vomiting,and total parenteral nutrition (TPN) without VitB_ 1 were main causes of VitB_ 1 deficiency,which might be the main causative factor in WE.

Objective To observe the effects of leptin on the proliferation and differentiation of human preadipocyte in vitro, and to explore the possible mechanism of the generation of obesity regulated by leptin. Methods The human preadipocytes were isolated from human subcutaneous adipose tissue of abdomen and cultured in vitro. The effects of leptin (0-1 000 ng/ml) on the proliferation, lipid accumulation and the mRNA expression of PPAR-γ2 and C/EBP-α, which are the differentiation and transcription factor of human preadipocyte, were analyzed by the methods of MTT, cell counting, extracting stained intracytoplasmic lipid with oil red O and RT-PCR. Results Leptin (1 000 ng/ml) could stimulate the proliferation, lipid accumulation and the mRNA expression of PPAR-γ2 and C/EBP-α (P<0. 05). There were not obvious effects on the proliferation and lipid accumulation in the groups of lower (10 ng/ml) and common (100 ng/ml) concentration (P>0. 05). Conclusion Leptin in higher concentration can stimulate the proliferation and differentiation of preadipocye in vitro, which indicates that leptin may regulate the generation of obesity through acting on the proliferation and differentiation of preadipocyte at the pathologic state of leptin resistance and high leptin concentration in serum.

Objective To evaluate the value of ultrasonic quantitative method in the diagnosis of liver fibrosis in chronic hepatitis B (CHB) patients. Methods Ultrasonography was performed in 186 CHB patients who underwent liver biopsies. Fifteen indices including liver capsule thickness and fourteen texture parameters of gray level co-occurrence matrix were extracted from standard sonograms and compared with fibrosis stages by histopathology. The status of liver fibrosis was divided into five stages from S0 to S4 by histopathology based on the disease severity. ANOVA and Spearman correlation analysis were applied to analyze the differences and relationships between these indices and pathological stage, respectively. Then discriminant analysis models were established based on the indices for quantitative diagnosis of liver fibrosis. Results Among the fifteen indices, including liver capsule thickness, only the variance (F=0. 55, r=0. 06; both P>0. 05), sum average (F=0.61, both r=0.05 ; P>0.05), sum entropy (F=1.68, r=0.09; both P≥0.05) and entropy (F=1.39,r=0.12; both P>0.05) were not significantly associated with the stages and not manifested linear correlation. Using biopsy results as gold standard, the correct rank rate of discriminant analysis model analysis in the patients staged from S0 to S4 were 80. 0%, 64. 9%, 61.3%, 74. 1% and 80.6 %, respectively. There were 73.1% of cross-validated cases who were accurately classified by the model analysis. The sensitivity, specificity and accuracy in patients with stage ≥ 1 were 97. 6%,80.0% and 91.9%, respectively; those in patients with stage≥2 were 92.1%, 89.7% and 90.9%,respectively; those in patients with stage≥3 were 94.8%, 96.1% and 95.7%; and those in patients with stage 4 were 80. 6%, 97.4 % and 94.6%, respectively. When considered S0 as no fibrosis, S1 as mild fibrosis, S2 and S3 as moderate to severe fibrosis and S4 as early cirrhosis, the consistence rates between discriminant analysis model and biopsy result were 81.7%, 78. 4%, 56. 9% and 90.3%,respectively. There were 74.7% of cross-validated cases who were correctly classified. The sensitivity, specificity and accuracy of the models for determining the fibrosis severity in patients≥mild fibrosis were 97.6%, 81.7% and 92.5%, respectively; those in patients ≥ moderate to severe fibrosis were 83. 1%, 94.8% and 89.2%, respectively; those in patients with early cirrhosis were 90.3%, 93.5% and 93.0%, respectively. Conclusion As a novel and noninvasive method, ultrasonic texture analysis could quantitatively determine liver fibrosis in CHB patients and is worthy of further investigation.
