Translational medicine has become the current focus in the field of medicine and health.To promote the development of translational medicine,the government should play multiple roles as planner,investor,coordinator,and supervisor,and to take its due responsibilities.

Objective To investigate epidemiological and clinical features of patients with clonorchiasis sinensis infection. Methods The epidemiological, clinical, laboratory and treatment data of clonorchiasis patients in Department of Infectious Diseases, Second Affiliated Hospital, Harbin Medical University from 2002 to 2004 were retrospectively analyzed. Results Sixty-eight point two percent patients had a history of eating raw freshwater fish and shrimp. Patients with occupations as cook, fish stock man, fishing man and fishmonger accounted for 22.6%. The transmission route was not clear in 9.1% of patients. The common clinical manifestations were abdominal pain (60.3%), fatigue (52.3%), diarrhea (33.0%), anorexia (69.3%), jaundice (23.9%), hepatomegaly (59.1%), splenomegaly (8.0%), dizziness (20.9%), fever (5.7%) and biliary colic (14.8%). Twenty-eight point four percent were asymptomatic. Other findings included liver dysfunction (70.4 %) and eosinophile granulocyteosis(69.3 %). Negative rate of stool egg of clonorchis sinensis after treatment with praziquantel or albendazole was 91.9% or 86.5%, respectively. There was no significant difference between the two groups ( χ2 = 0.561, P = 0.454). Conclusions Clinical manifestations of patients with clonorchiasis sinensis are complicated and often accompanied with liver dysfunction. Clonorchiasis sinensis is often misdiagnosed and should be paid much attention.

Nuclear DNA content of 32 cases of prostate adenocarcinoma diagnosed 1986-1991 was determined by flow cytometry, with the use of paraffin-embedded archival tissue. The present study was done to define the relationship between clinical stage, histopathological grade, and DNA ploidy. Aneuploidy was found in 10(31.3%) cases including 7 cases of near-tetraploidy. Among diploid tumors, 36.4% were localized disease(stage A and B), 13.6% were characterized by invasion outside the prostate(stage C), and 50.0% showed distant metastasis(stage D). Among aneuploid tumors, 10.0% were stage B, 50.0% stage C, and 40.0% stage D. The degree of glandular differentiation was characterized by the Gleason score and the percentage of sampled tissue involved by carcinoma was graded by Dhom's method. Apparent correlation was found between Gleason grade and Dhom grade(P<0.05). All 13 tumors with a Gleason grade I(score of 2 to 5) were diploid. Four of 9 tumors with a Gleason grade II(score of 6 to 7) were aneuploid(near-tetraploidy 33.3%, aneuploidy 11.1%) and 60.0%, of tumors with a Gleason grade III(score of 8 to 10) were aneuploid(near-tetraploidy 40.0%, aneuploidy 20%). The percentage of aneuploid cases increased with advanced clinical stage, but the relationship between aneuploidy versus clinical stage was not significant. However, it can be concluded that DNA ploidy correlates well with Gleason grade(p<0.05), which may have predictive prognostic value for prostate adeno-carcinomas.

Objective To evaluate the Flavivirus specific monoclonal antibody(McAb) 2A10 as detective antibody for simultaneously identify tick borne encephalitis virus( TBEV), Japanese encephalitis virus( JEV), dengue ( DEN )-2, DEN-4 and yellow fever virus ( YFV ) by antibody microarray technique.Methods The antibody microarray was developed by spotting TBEV, JEV, DEN-2, DEN-4 and YFV specific McAb on chip as capture antibodies. After incubating with cultured viral supernatants of the above viruses, CY3 labeled detective antibody 2A10 was added to the chips. After reaction, the antibody microarray was scanned and the results were analyzed. By comparing the signal intensities of different spots on chips,the detecting titre and sensitivity of 2A10 for Flavivirus were determined, and the value of 2A10 in detection of Flavivirus was evaluated. Results The hybridization results demonstrated that the titre of 2A10 for Flavi2A10 was specific for Flavivirus and could be used as universal detective antibody for Flavivirus on antibody microarray.

Glycogen storage diseases(GSD) are inherited disorders affecting glycogen metabolism and type I GSD is due to the absence or deficiency of glucose-6-phosphatase(G6Pase) enzyme in the liver, kidney, and intestinal mucosa. The defect leads to inadequate hepatic conversion of G6P to glucose and thus make affected individuals susceptible to fasting hypoglycemia, and the accumulation of glycogen occurs in the liver and other organs. Type Ia is the most common form of GSD and clinically growth retardation may manifest of GSD itself rather than growth hormone deficiency(GHD), but we experienced a case of type I GSD with GHD in a 14-year-o1d male. The height was 125 cm, compatible with 50 th percentile of height of 8 years of age. He has doll-like face with fat cheek, relatively thin extremities, and metabolic acidosis, hyperuricemia, hypoglycemia, hyperlipidemia. GH stimulation test with clonidine and L-dopa revealed that the patient had decreased GH secretion. After laboratory work up including liver biopsy, he was diagnosed as type I GSD. Hypoglycemia was managed with frequent feeding with high starch diet(uncooked cornstarch). Metabolic acidosis and hyperuricemia were treated with sodium bicarbonate, allopurinol and probenecid. The patient is being followed at out-patient clinic with clinical improvement after of diet therapy and GH administration.

The assocication between human papillomavirus infection (HPV) and cervical lesionhas been well established. for detection and typing human papilloma virus deoxyribonucleic acid in cervical tissues, Southern blot hybridzation and polymerase chain reaction are commonly regarded as reference standard methods. However it has the limitation includeing technical difficulty, safety, subjectivey in result interpretation. Recently the chemilnuminescent molecular hybridization assay method has been windely used and it has been known that it can detect less hybridization assay method has been windely used and it has been known that it can detect less then 1 pg of DNA in a 100n1 aliquot of a crude specimen. This study was perfomed to determine the usefulness of hybrid capture HPV DNA assay for detecting low-risk and high-risk human papillomaviruses in histologically confirmed normal, cervical intraepithelial lesion(CIN) and invasive squamous cell carcinoma of the cervix, and to compare the correlation among cervical cytology, hiopsy finding and HPVs infelction ,and to detirmine whether the additon of the hybrid capture test to cytologic studies would improve the ability to identify signifcant lesions. Cervical cytologic smears, hybrid capture HPVs DNA assay, and pucnh bhiopsies were performed on 78 women who have normal cervix(28cases),cervical intraepithelila lesion (24cases), and invasive squamous cell carcinoma(26cases). At first the probes for low-risk HPV(6,11,42,43,44) and the proves for high-risk HPV(16,18,31,33,35,45,51,52,56)were used and secondly retyping was done for HPV 16 abd 18 in high-risk HPV positive cases.the results obtained were as follows; 1. Low-risk HPVs infections were 14.3% and 8.3% in normal cervix and cervical intraepithelial lesion respectively. High-risk HPVs infection were 7.1%, 70.8% and 73.1% in normal cervix, cervical intraeithelial lesion and squamous cell carcinoma respecitively. These was highly significant corelation between positive high-risk HPVs test, cervical intraepithelial lesion and squamous cell carcinoma. 2. Positivities of low and high-risk human papillomaviruses in patients with negative cytologic result were 9.1% and 15.1% respectinvely. 3. In patients with high-risk human papillomaviruses infection, human papilloma viurs 16 and 18 types were detected in 47.4% and 13.2%, respectinvely, and both HPV 16 and 18 positive and negative detention were 15.7% 23.7% respectinvely. Among 12patinent of cervical intraepithelial neoplasia with high risk HPVs infection, HPV 16 was detected in 66.6% and HPV 18 in 16.7% Among 24 squamous cell carcinomas with high risk HPVs infection, HPV 16was detected in 41.7% and HPV 16 in 12.5% and both HPV and 18 in 25% 4. In patients without koilocytosis by cervical tytology, low and high-risk human papillomaviruses or both were positive in 30.7% 5. In patients with positive high-risk HPVs, sensitivitives of koilocytosis were 64% and 69% in histologic and cytologc diagnosis, and specificities and specifictites were 58.5% and 62% respectively. Above result suggest that detection for high-risk human papilloma viruses type by hybrid capture assay improves the management of cervical intraepithelial neoplasia and is more useful method over cervical cytology only.
