Objective To investigate the changes of epidemiological and clinical features of patients with hemmorrhagic fever renal syndrome (HFRS) over past 10 years in Harbin region. Methods The epidemiological, clinical and laboratory data of patients with HFRS in 1995 and 2005 in The Second Affiliated Hospital of Harbin Medical University were retrospectively analyzed. The genotypes of Hantaan virus of patients in 2005 having an onset within 5 days were examined by reverse transcriptase polymerase chain reaction (RT-PCR). Positive rates in different groups were compared using chi square test. Results One hundred and sixty-five cases were collected, including 78 in 1995 and 87 in 2005. There were significant differences in epidemiological area (X2=10. 483, P<0.05), clinical classification (X2=7. 907, P<0.05), clinical stage (X2=10.500, P<0.05), the variance of total white blood cells (X2=20. 315, P<0.01) and blood sugar changes (X2=9.958, P<0.01) between two groups of patients. Bases on clinical manifestations, there were significant differences in two groups (1995 and 2005): headache, 70.5% and 50.6% (X2=6.812, P<0.01); lumbago, 60.3% and 40.2% (X2=6.598, P<0.05); fossaorbitalis pain, 50.0% and 19.5% (X2=17.019, P<0.01); melena, 60.3% and 40.2% (X2=6.598, P<0.05); bleeding point and eeehymosis, 50.0% and 33.3% (X2=4.715, P<0.05) ; flush of faee, neck and upper chest, 59.0% and 40.2% (X2=5.782, P<0.05); membrane-like object in urine, 44.9 % and 29.9% (X2=3.964, P<0.05) rates of thrombocytopenia, 79.5% and 64.4% (X2=4.615, P<0.05) ; rates of liver dysfunction, 50.0% and 80.5% (X2=17.019, P<0.01); rates of cardiac muscle enzymoiogy dysfunction, 50.0% and 92.0% (X2=36.003, P<0.01). The genotypes of patients in 2005 were Hantaan virus (34.8%) and Seroul virus (65.2%). Conclusion The differences in epidemiological and clinical feature of patients with HFRS over past 10 years may be related with the change of virus genotypes, and further study should be done.

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.

Objective To investigate the effects of Chinese herb formula Tangtongfang by bathing the affected feet of patients with diabetic peripheral neuropathy (DPN) in the pattern of Qi deficiency and blood stasis. Methods A parallel, randomized, controlled clinical research was performed. 70 diabetics in the inpatient and outpatient divisions of the Department of Endocrinology, Guanganmen Hospital, from January 2005 to October 2007 were investigated. They were divided randomly into two groups, treatment group and control group, 35 cases in each group. Before study, there were no statistic differences between the two groups, including gender, age, course of diabetes mellitus(DM), course of DPN, blood glucose (including fasting blood glucose and postprandial blood glucose), traditional Chinese medicine(TCM) symptom scores and nerve conduction velocity (NCV). The treatment group were treated with Tangtongfang bathing and the control group were treated with warm water bathing. Each group was also administered Vitamin B1 20 mg, t.i.d and Vitamin B6 20 mg, t.i.d respectively. All patients were keeping their routine treatment and diabetic care to control their blood glucose, such as diets, practices and drugs. Clinical symptoms and electrophysiological tests in diabetic peripheral neuropathy syndrome were investigated. The period of treatment was 8 weeks.Results After study, 9 cases retreated from this clinical trial totally, 4 cases in the treatment group whereas 5 in the control group. Among 4 common single symptoms, coolness feeling of the feet of diabetic patients was significantly improved (P<0.05) after bathed with Tangtongfang. The change of TCM symptom scores and tibialis NCV was significantly improved (P＜0.001, P<0.05) in the treatment group. The improvement ratio was 45.2% and 61.3% in the treatment group, while was 10% and 3.3% in the control group. In each group there was no statistical difference between pre-and post-study with blood test, urine test, blood ALT, blood BUN and Cr, ECG examination (P>0.05). No adverse event was observed in each group.Conclusion Tangtongfang bathing improved several symptoms of patients suffering from DPN, especially the symptom of coolness feeling of the patients' feet. No adverse event was observed. This result showed that Tangtongfang bathing was worthy of using as a safe agent in treatment of DPN.

Objective To establish high level expression system of exogenous hepatocyte growth factor(HGF) protein in mouse livers by in vivo gene transfection and to observe the inhibition effect of exogenous HGF on hepatocyte apoptosis in mice. Methods Mice were divided into four groups, with 10 mice in each arm, which were injected with control solution, empty pcDNA3 plasmids, pCMV-HGF plasmid or 0.9% sodium chloride solution by tail vein. Enzyme-linked immunosorbent assay(ELISA) was used to determine the peak level and the expression duration of HGF protein in the peripheral blood and liver tissue. Western blotting was performed to measure the Caspase-3, tBid, Bax and Cytochrom C in the hepatocyte homogenatea and mitochondrion. Results HGF protein was detected in the mice blood as early as 4 hours after single injection of pCMV-HGF plasmid. The peak level of HGF protein in liver and plasma was respectively achieved by 8 hours and 12 hours after first injection while HGF protein was still detectable in the blood 6 days after the initial injection. D-Galactosamine/lipopolysaeeharide (LPS) led to obvious hepatocyte apoptnsis and induced an increased concentration of tBid, Bax, Caspase-3 and Cytochrom C in the hepatocyte homogenates and mitochondrion. Compared to sodium chloride control group and empty pcDNA3 protected group, the expression of tBid, Bax, Caspase-3 and Cytochrom C decreased in pCMV-HGF plasmid protecting group. Conclusions Hepatocyte apoptosis can be inhibited by exogenous HGF protein expression in mouse livers, which is induced by in vivo gene transfection. Moreover, it may inhibit the activation of downstream apoptotic proteins by blocking the expression of tBid.
