Abstract
We have explored the molecular basis of the cAMP-induced stabilization of lactate dehydrogenase A (LDH-A) mRNA and identified four cytoplasmic proteins of 96, 67, 52, and 50 kDa that specifically bind to a 30-nucleotide uridine-rich sequence in the LDH 3'-untranslated region with a predicted stem-loop structure. Mutational analysis revealed that specific protein binding is dependent upon an intact primary nucleotide sequence in the loop as well as integrity of the adjoining double-stranded stem structure, thus indicating a high degree of primary and secondary structure specificity. The critical stem-loop region is located between nucleotides 1473 and 1502 relative to the mRNA cap site and contains a previously identified cAMP-stabilizing region (CSR) required for LDH-A mRNA stability regulation by the protein kinase A pathway. The 3'-untranslated region binding activity of the proteins is up-regulated after protein kinase A activation, whereas protein dephosphorylation is associated with a loss of binding activity. These results imply a cause and effect relationship between LDH-A mRNA stabilization and CSR-phosphoprotein binding activity. We propose that the U-rich CSR is a recognition signal for CSR-binding proteins and for an mRNA processing pathway that specifically stabilizes LDH mRNA in response to activation of the protein kinase A signal transduction pathway.

Abstract
Expression of the lactate dehydrogenase A subunit (LDH-A) gene can be controlled by transcriptional as well as posttranscriptional mechanisms. In rat C6 glioma cells, LDH-A mRNA is stabilized by activation and synergistic interaction of protein kinases A and C. In the present study, we aimed to identify the sequence domain which determines and regulates mRNA stability/instability by protein kinase A and focused our attention on the 3'-untranslated region (3'-UTR) of LDH-A mRNA. We have constructed various chimeric globin/lactate dehydrogenase (ldh) genes linked to the c-fos promoter and stably transfected them into rat C6 glioma cells. After their transfection, we determined the half-life of transcribed chimeric globin/ldh mRNAs. The results showed that at least three sequence domains within the LDH-A 3'-UTR consisting of nucleotides 1286-1351, 1453-1471, and 1471-1502 are responsible for the relatively rapid rate of LDH-A mRNA turnover in the cytoplasm. Whereas chimeric globin/ldh mRNAs containing the base sequences 1286-1351 and 1453-1471 were not stabilized by (Sp)-cAMPS, an activator of protein kinase A, instability caused by the 1471-1502 domain was significantly reversed. Additional deletion and mutational analyses demonstrated that the 3'-UTR fragment consisting of the 22 bases 1478-1499 is a critical determinant for the (Sp)-cAMPS-mediated LDH-A mRNA stabilizing activity. Because of its functional characteristics, we named the 22-base region "cAMP-stabilizing region."

Abstract
The lactate dehydrogenase-A (LDH-A) gene, whose product plays a pivotal role in normal anaerobic glycolysis and is frequently increased in human cancers, is highly regulated at the transcriptional and posttranscriptional levels. Our laboratory has carried out extensive studies concerning the regulation of LDH-A subunit expression. We have elucidated complex regulatory mechanisms by identifying multiple cis-acting promoter elements including functional sites for Sp1 and c-Myc interactions as well as sites that interact with the protein kinase A and protein kinase C substrates, CREB and AP1, respectively. Furthermore, we have reported the existence of a CRE-dependent silencer element in the LDH-A promoter. LDH-A expression is additionally regulated through the protein kinase A and C signal pathways at the posttranscriptional level, specifically mRNA stability.

Abstract
To study the mechanism of cinnarizine in preventing motion sickness, TXB2, 6-Keto-PGF1 alpha in rats' blood plasma and Na(+)-K(+)-ATPase activity in the endothelial cells of their cerebellar capillary were measured and analysed by a radioactive immunity analyser and a computer image system. The results showed that TXB2 and 6-Keto-PGF1 alpha in rats' blood plasma in the cinnarizine preventing group (CPG) decreased remarkably, compared with those in the motion sickness group(MSG) (p < 0.05). The activity of Na(+)-K(+)-ATPase in the endothelial cells of rats' cerebellar capillary in CPG was higher than that in MSG (p < 0.01). The authors suggest that the lower concentration of TXB2 and 6-Keto-PGF1 alpha in rats' blood plasma in CPG is closely related to cinnarizine which prevents Ca2+ from entering into the platelets and into the endothelial cells of blood vessels. The higher activity of Na(+)-K(+)-ATPase in the cerebellum may be caused by cinnarizene which dilates the blood vessels in the brain, increases the blood flow therein, and hinders Ca2+ from getting into the cerebellum cells. These change are believed to be the important mechanism of how cinnarizine prevents motion sickness.

Abstract
In order to determine the replication sites of hepatitis C virus, the in situ hybridization and immunohistochemical technique using digoxin-labeled 531 bp plus-strand and minus-strand HCVRNA probes were employed to detect HCVRNA in the liver tissues, bone marrow mononuclear cells and peripheral blood mononuclear cells (PBMCs) from the patients with chronic hepatitis C, and in HCV transfected COS cells. The results showed that both plus-strand and minus-strand HCVRNA were detected in 80% of liver tissues (4/5). Plus-strand HCVRNA could be detected in 90% of PBMCs and bone marrow mononuclear cells (18/20), minus-strand HCVRNA in 25% of PBMCs. In HCV transfected COS cells, plus-strand HCVRNA distributed evenly in 20% cellular nuclei and cytoplasms. No minus-strand HCVRNA was detected in the bone marrow mononuclear cells and HCV transfected COS cells. The positive signal appeared in more cells when the liver tissues, PBMCs and marrow mononuclear cells were hybridized by plus-strand probes than when hybridized by minus-strand probes. Our results suggested that the hepatocytic cytoplasms and PBMC cytoplasms were the replication sites of HCV, but the marrow mononuclear cells were not the replication sites of HCV although they were infected by HCV. HCV infection might be accounted for the pathogenesis of chronic hepatitis and relapse of hepatitis C after liver transplantation.

Abstract
In order to make full and effective use of patellar tendon (middle one-third) during reconstruction of anterior cruciate ligament, we designed bone-patellar tendon-tendon of quadriceps femoris free graft with impacting bone technique and 38 cases were treated by this method. Follow-up for 2 years and 7 months showed that the clinical results were good. The exellent and good rate was 89.7%. Clinical results indicated that the fixation of this reconstructive method was firm and grafts in the joint cavity were patellar tendon tissue. The anterior medial rotatory instability of the knee joint could be corrected with the same graft that have enough length. The experience of acute rupture of anterior cruciate ligament and the rupture of anterior cruciate ligament combined with injury of meniscus were reported.

Abstract
To understand the influence of hBMP on the articular cartilage, we investigated the expression of osteocalcin (BGP) and hBMP, and calcium deposit in cartilage matrix induced by hBMP. Under the inducing of hBMP, chondrocytes in cartilage pieces begun to express BGP and hBMP. The hBMP promoted calcium deposition in the cartilage matrix, hBMP made some chondrocytes further differentiat into osteoblast-like cells. We consider that these osteoblast-like cells might be other source of osteoblasts in endochondral osteogenesis.

Abstract
OBJECTIVE To investigate the role of nitric oxide (NO) in the pathogenesis of asthma, we observed the influence of L-NG-arginine-methylester (L-NAME), the inhibitor of nitric oxide synthase (NOS), on the contraction of isolated guinea pig tracheal smooth muscles and observed the changes of NOS in the guinea pig asthma model lung tissues using histochemical detection. METHODS Male Hartley guinea pig isolated tracheal ring were incubated with L-NAME 2.0 mmol/L for 30 min and histamine was given to make a concentration response curve. The sections of guinea pig asthma model lung tissues were stained with NADPH diaphorase. RESULTS The histamine concentration response curve was significantly shifted upward in the L-NAME incubated group, the maximal response increased by 170% compared with that of control group. The numbers of alveolar macrophages were significantly increased and NADPH diaphorase staining was positive in asthma model group, in contrast, the alveolar macrophages were hardly seen and there was almost no positive staining of NOS in the control group. CONCLUSIONS The inhibition of NO synthesis of guinea pig respiratory tract with L-NAME results in a marked increase in airway contraction in vitro after histamine provocation. This result indicate that NO has relaxant effect on tracheal smooth muscles and may decrease airway responsiveness to histamine. The increased alveolar macrophages and positive stained NOS in the lung tissues of asthma model indicate that NO, which is synthesized by the NOS in alveolar macrophages, may play an important role in asthma pathogenesis.

Abstract
To find out the relationship between human bone morphogenetic protein's activity and its carrier and to document the clinical application of BMP, we investigated six kinds of BMP carrier's influence upon hBMP's osteogenic activity with small sample size at first. Then three kinds of carriers selected from the six, added with the seventh carrier, were investigated with large sample size. The result showed that the compound of hBMP and hDDBM had best osteogenic ability. The human bone matrix had been formerly demineralized and extracted without hBMP. The hDDBM showed porous structure under SEM, its mean pore's diameter was 127 +/- 34 microns. It was demonstrated that the function of demineralized bone matrix extracted without BMP (i.e. DDBM) was related not only to its pore's diameter, but to the fibrolike matter in it as well. With the method of BMP bioassay, BMP was composited with carrier, then the compound was injected into the calf of mouse. This made BMP's bioassay become simple and reliable.

Abstract
Experimental chronic gastritis (ECG) models were established in rats by inserting a spring into pyloric canal as well as feeding sodium deoxycholate. An experiment was undertaken to observe the therapeutic effects of three formulas of traditional Chinese medicine "Shipitong", "Ganpingyangwei" and "Weile". The experimental results show that all of the three decoctions can reduce gastric pH and bile acid of the ECG rats and make gastric mucosal histomorphology of these rats change markedly.

Abstract
A two-frequency beam from a Zeeman laser scatters elastically from an isotropic medium, such as randomly oriented viruses or other particles suspended in water. The Zeeman effect splits the laser line by 250 kHz, and beats can be seen electronically in the signal from a phototube that views the scattered light. There are independently rotatable half-wave and quarter-wave retardation plates in the incident beam and a similar pair in the observed scattered beam, plus a fixed linear polarizer directly in front of the detector. Each of the four retarders has two angular positions, providing a total of 16 possible polarization cases. For each of the 16 cases, there are three data to be collected: (1) the average total intensity of the scattered light, (2) the amplitude of the beats in the scattered light, and (3) the phase shift between the beats of the scattered light and those of a reference signal from the laser. When a singular value decomposition technique is used, these threefold redundant data are rapidly ransformed into a best-fit 4 × 4 Mueller scattering matrix. We discuss several different measurement strategies and their systematic and statistical errors. We present experimental results for two kinds of particle of wavelength size: polystyrene spheres and tobacco mosaic virus. In both cases the achiral retardation element M(34) of the Mueller matrix is easily measurable.

Abstract
Among Han nationality Chinese and living in the northern area of the Yellow River, 120 patients suffering from Behçet's disease and 100 unrelated healthy individuals were typed for histocompatibility antigens (HLA)-A, -B, -C, and -DR and -DQ antigens. HLA-DR and DQ typing was performed on B-lymphocyte separated with Lympho-B-Kwik. The HLA-antisera were provided by 11th IHWC. Bf alleles and C4 allotypes were determined by immunofixation agarose-gel electrophoresis. HLA-B51 was found in 67/120 (55.83%) patients and in 12/100 (12%) controls, the Chi-square and relative risk values were 45.54 and 9.27, respectively (p < 0.0005). C4AQ0 frequency was significantly increased in the patient group. In the complete form group HLA-B51 was observed more frequently (62.79%). No significant differences of other HLA antigens, frequencies, Bf or B4 alleles were found between the groups.
