This article summarized two medical cases of Professor SHI Da-zhuo treating acute myocardial infarction by Yiqi Huoxue Tuodu Shengji TCM therapy on the basis of conventional Western medicine therapy. Comparison of echocardiography before and after treatment showed that Yiqi Huoxue Tuodu Shengji TCM combined with conventional Western medicine therapy could inhibit the expansion of atrium and ventricle, improve the cardiac ejection fraction and improve the cardiac function after acute myocardial infarction, which could provide references for integrated traditional Chinese and Western medicine therapy for acute myocardial infarction.

Foodbome viruses are defined to be viruses that can lead to human diseases through food. In accordance with the different origin, foodborne viruses can be divided into two kinds: intestinal viruses and zoonotic viruses. The former include those viruses that can be transmitted to person via fecal-orally route. The latter include those zoonotic viruses that chiefly transmitted to person through livestock and poultry products. This paper expounds foodborne viruses categories, biology nature, epidemiology character, and study circumstance, and clarifies the molecular biological methods and problems on the base of the polymerase chain reactions, and presents the development direction and application perspective of the foodbome viruses study.

Aim To explore protective effect of Sanweitanxiang powder on isoproterenol-induced myocardial ischemia in rats, and its possible mechanism. Methods A myocardial ischemia model in rats was established by intraperitoneal injection of isoproterenol (Iso 5 mg?kg-1 once a day ,for 3 days). After ip 24 h, The levels of LDH、CK in serum and NOS、iNOS and NO in the myocardium tissue were measured. The myocardial area suffered from ischemia injury were determined. The changes of myocardial ultrastructure were observed with electron microscope. Results Compared with model group, the levels of LDH、CK and infarction size of myocardium were decreased. The concentrations of NOS, iNOS and NO in myocardium were less than those in the model group. The results of myocardial ultrastructure indicated that the partial mitochondria crista and myofibrils sprase, z band unaltered in Sanweitanxiang powder groups. Conclusion Sanweitanxiang powder has a significant protective effect on isoproterenol-induced myocardial injury in rats. By improving the energy metabolism of myocardium,the structure and function of mitochondria and reducing the NO release.

Objective To observe the effects of early rehabilitation on the serum neuron specific enolase (NSE) levels of patients with acute cerebral infarction.MethodsSixty patients with acute cerebral infarction were randomly divided into a rehabilitation group and a control group. All received routine treatment at the acute stage, including anti-platelet aggregation medication, drugs for improving microcirculation, neurotrophic agents and prompt treatment of any complications. Patients in the rehabilitation group also received systemic rehabilitation training beginning immediately after their vital signs had been stabilized. NSE in serum was assayed before treatment and after 3, 7and 14 days. National Institutes of Health stroke scale (NIHSS) scores were evaluated at each time point, and the two groups were compared.ResultsThere was no significant difference in serum NSE or NIHSS scores between the two groups pre-treatment. Both groups improved to a certain extent, but the improvements in the rehabilitation group were significantly better than in the control group, as their NSE levels at 7 days and NIHSS scores at 14 days were both significantly better.ConclusionsEarly rehabilitation intervention contributes to reducing serum NSE levels after acute cerebral infarction, lessening brain injury, and thereby promoting the recovery of damaged neural function.That may be one of the mechanisms by which early rehabilitation promotes functional recovery in patients with acute cerebral infarction.

Objective To study the relationship between environmental chemical elements,vires infection and dilated cardiomyopathy(DCM).Methods In 2008,233 patients with DCM(case group)and 150 patient with stable angina(control group)were chosen in Liaocheng People's Hospital and Yanggu People's Hospital,Shandong province.Population distribution and disease history were surveyed in the two groups.Human myocardial antibody IgG(AMA-IgG),Coxsackie B virus IgG(CBV-IgG),Adenofirus antibody IgG(ADV-IgG)were detected by ELISA in both the case group and the control group.Serum trace elements were detected in the two groups.The general chemical and toxicological indicators in drinking water of the high-and the low-incidence aireas of the disease were control group[60.00%(90/150),χ2=13.80,P<0.01)].Per capita annual income(Yuan,RMB)in the case group (3207.82±618.51)was lower than that of the control group[(5086.61±886.12),t=24.40,P<0.01].Personal alcohol consumption in the case group[(175.00±160.50)g/d]was higher than that of the control group[(110.22±100.03)g/d,t=4.40,P<0.01)].The rate of myocarditis in the case group[5.15%(12/233)]was higher than ADV-IgG in the cage group were 7.78%(7/90),6.67%(6/90)and 6.67%(6/90),respectively.Compared with those in the control group[3.33%(2/60),5.00%(3/60)and 5.00%(3/60),χ2=1.26,0.18,0.18,all P>0.05],no mg/L]in drinking water of the high-incidence areas were significantly higher than that of iron[(0.39±0.67)mg/L,t=2.11,P<0.05]and that of manganese[(0.15±0.14)mg/L,t=3.01,P<0.01]in the low-incidence arefas.The content of semm iron[(69.1±57.8)μmol/L]in the case group evidently exceeded the normal range(15.6-35.9 μmol/L)and obviously higher than that in the control group[(20.0±17.5)μmol/L,t=5.04,P<0.01].Conclusions Theso data do not support that DCM is related with persistent virus infection and autoimmunization.DCM is probably related with low incomes,high alcohol consumption,myocarditis,high iron and manganese contents in drinking water and high content of serum iron.

Inosine 5′-monophosphate dehydrogenase (IMPDH) is a key enzyme catalyzing the rate-limiting step of de novo nucleotide synthesis in vivo. In recent years, it has become a therapeutic target for anti-virus, anti-bacterial, anti-cancer, anti-parasitic and other diseases. IMPDH inhibitors have been shown to inhibit viral prolife-ration in host cells by depleting guanosine 5′-monophosphate (GMP), the raw material required for viral replication in host cells, with broad-spectrum antiviral properties. In order to find novel anti-coronavirus drugs, this study screened 22 potential IMPDH inhibitors from 70 000 natural small molecule libraries based on IMPDH protein structure using molecular docking and ROC calculation for virtual screening. With ribavirin as the positive control drug, Huh7 cell and H460 cell models were used to verify the anti-coronavirus HCoV-229E and HCoV-OC43 activities of 22 selected target compounds. Among them, compounds 11, 12, 15 and 16 showed inhibitory activity against coronavirus HCoV-229E. The compounds 4, 12, 13 and 15 showed inhibitory activities against coronavirus HCoV-OC43. 12 and 15 showed significant inhibitory activity against both two coronaviruses, and their efficacy was similar to ribavirin at the same dose, which can be further studied as a lead compound for IMPDH inhibitors.

Objective To establish a method for simultaneous detection of norovirus (NV),rotavirus (RV), astrovirus (AV) and hepatitis A virus (HAV) by multiplex reverse transcriptionpolymerase chain reaction (RT-PCR). Methods Specific primers of the four viruses were designed based on the high conserved sequences, the reaction system and conditions optimized and the specificity and sensitivity confirmed. The method was then applied to detect the four viruses in clinical samples. Results The steady detection limits were 100 pg/ml for hepatitis A virus, 50 pg/ml for rotavirus, norovirus and astrovirus respectively. When the developed method was used to detect clinical fecal samples, 62(48.44%)were iden tified as rotavirus, 8 (6.25%) as norovirus, 11 (8.59%) as astrovirus and 4 (3.12%) as hepatitis A virus in a total of 128 samples. Conclusion Data from our study showed that multiplex RTPCR system could be used to simultaneously detect the four viruses in routine monitoring and risk assessment in disease outbreaks with high specificity and sensitivity.
