Objective: To observe the effects of moxibustion at Shenshu (BL 23), Zusanli (ST 36) and Shenque (CV 8) on the energy metabolism and endocrine metabolism indicators of rats undergoing one-time exhaustive swimming, and to explore the differences between moxibustion at different points in the effects on anti-exercise fatigue. Methods: Forty-eight male SPF rats were randomly divided into a blank group, a model group, a non-meridian and non-acupoint group, a Shenshu (BL 23) group, a Zusanli (ST 36) group, and a Shenque (CV 8) group using random number table method, with eight rats in each group. Except for the blank group, rats in the other groups were subjected to replicating the one-time exhaustive model using the weight-bearing swimming experiment. Except for the model group, the other model rats received mild moxibustion immediately after swimming. Rats in the non-meridian and non-acupoint group received mild moxibustion at bilateral subcostal non-meridian and non-acupoint points, those in the Shenshu (BL 23) group received mild moxibustion at bilateral Shenshu (BL 23), those in the Zusanli (ST 36) group received mild moxibustion at bilateral Zusanli (ST 36), and those in the Shenque (CV 8) group received mild moxibustion at Shenque (CV 8) for 15 min. Four hours after the exhaustive swimming, femoral artery blood was collected to detect blood lactate (BLA), lactate dehydrogenase (LDH), creatine kinase (CK), creatinine (CRE), blood urea nitrogen (BUN), cortisol (C) and testosterone (T) levels, and calculate the T/C ratio. Results: Compared with the blank group, rat's serum levels of BLA, LDH, CK, BUN and C in the model group and the non-meridian and non-acupoint group were increased, and serum levels of CRE and T, and T/C ratios were decreased (P<0.01 or P<0.05); compared with the model group and the non-meridian and non-acupoint group, the serum levels of BLA, LDH, CK, BUN and C in the Shenshu (BL 23) group, Zusanli (ST 36) group and Shenque (CV 8) group were decreased, and the serum CRE and T levels, and the T/C ratios were increased (all P<0.01); compared with the Shenshu (BL 23) group, the serum CK level was decreased in the Shenque (CV 8) group (P<0.01), the serum levels of T and C were decreased in the Zusanli (ST 36) group and Shenque (CV 8) group (P<0.01 or P<0.05), and the T/C ratio was increased in the Shenque (CV 8) group (P<0.01); compared with the Zusanli (ST 36) group, the serum CK and BUN levels were decreased (P<0.01, P<0.05), and the T/C ratio was increased in the Shenque (CV 8) group (P<0.05). Conclusion: Moxibustion at Shenshu (BL 23), Zusanli (ST 36) and Shenque (CV 8) shows different anti-fatigue effects by regulating the energy metabolism and endocrine metabolism in rats undergoing one-time exhaustive swimming. Moxibustion at Shenshu (BL 23) is better in promoting energy synthesis. Moxibustion at Shenque (CV 8) is more effective in regulating synthesis and decomposition of the skeletal muscle proteins.

Objective: To analyze the data of malignant tumor mortality and change in disease burden in Hebei province from 1973 to 2013. Methods: Cancer mortality rate, age-standardized mortality rate and the years of life lost due to premature mortality (YLLs) were calculated by using the data from three rounds of all death causes survey and database of cancer registry in Hebei during 1973-2013. Results: From 1973 to 2013, a linear upward of malignant tumor mortality was observed, with a 51.57% increase. The mortality rate during 1973-1975 was 98.52/100 000 and it was 149.33/100 000 during 2011-2013. During 1973-1975, the YLLs was 17.0/1 000 in males and 12.8/1 000 in females. While during 2011-2013, the YLLs was 23.2/1 000 in males and 15.9/1 000 in females. During 1973-1975, esophagus cancer, stomach cancer and liver cancer were top three leading causes of deaths. During 2011-2013, lung cancer, stomach cancer and liver cancer were main leading causes of deaths. During the past 40 years, the deaths of esophagus cancer and cervix cancer decreased dramatically, but the deaths of lung cancer and breast cancer increased sharply. Conclusions: The disease burden caused by malignant tumor is becoming more serious in Hebei. It is necessary to strengthen the primary prevention and screening of malignant tumor.

OBJECTIVETo investigate the relationship between heat shock protein 72 (Hsp72) and DNA genetic damage in peripheral blood lymphocytes of coke oven workers and the role of Hsp72 in protection of cells from genetic damage induced by coke oven emissions.

METHODSTwo hundred and sixty-seven coke oven workers and thirty controls without occupational PAHs exposure were investigated. Benzo[a]pyrene concentrations in the ambient air individually collected were assayed by high performance liquid chromatography (HPLC). Western Blot was used to measure Hsp72 levels and Comet assay was used to evaluate DNA damage degree. Personal information was collected by questionnaire.

RESULTSThe Hsp72 level (G+/-S(G)) and olive comet tail moment (G+/-S(G) of peripheral blood lymphocytes in high-exposure workers (1.24 +/- 0.42 and 4.49 +/- 1.24) were significantly higher than those in low-exposure workers (1.01 +/- 0.35 and 2.99 +/- 1.10, P < 0.05) and control (0.85 +/- 0.34 and 2.40 +/- 1.00, P < 0.05) respectively. The Hsp72 median level of all subjects was used as the limit to divide subjects into high Hsp72 level group and low Hsp72 level group. The rate with high Hsp72 level was 36.7%, 43.1% and 58.3% in control, low exposure and high exposure workers respectively and had a rising tendency following exposure level (P = 0.003). In high Hsp72 level group Hsp72 level in high exposure workers was significantly higher than that in control (P < 0.05), and there was a rising tendency along with the increase of exposed levels. But the olive comet tail moment had no significant difference among three exposed groups (P > 0.05). In low Hsp72 level group there no difference among three exposed groups about Hsp72 levels. The olive comet tail moment in high exposure workers was significantly higher than that in low exposure workers and control (P < 0.01) and high exposure workers in Hsp72 positive group and there was a rising tendency along with the increase of exposed levels. Hsp72 levels had strong negative correlation with the olive comet tail moment (r = -0.503, P < 0.01) in high exposure workers.

CONCLUSIONThe coke oven emissions can induce hsp72 expression. Hsp72 play a role of protecting cells from DNA damage induced by coke oven emissions.

OBJECTIVETo study the effect of tanshinone II A on the cell signal transduction system protein kinase B (Akt) in rats with hypertrophy of the myocardium induced by partial constriction of the thoracic aorta.

METHODSRat models of myocardial hypertrophy were established by the thoracic aorta partial constriction method. Forty-eight rats were randomly divided into the sham-operative group, the model group, the valsartan treatment group, and the low-, medium-, and high-dose tanshinone treatment groups. The heart mass index (HMI), left ventricular mass index (LVMI), ejection fraction (EF), left ventricular posterior wall (LVPW), and interventricular septal thickness (IVS) were detected by high-frequency ultrasonography. The myocardial fiber diameter (MFD) was detected by HE staining, and the contents of p-Akt and p-Gsk3beta in the myocardium were detected by Western blot.

RESULTSCompared with the sham-operative group, the levels of HMI, LVMI, LVPW, IVS, and MFD were increased respectively in the other groups (P<0.05); the contents of p-Akt and p-Gsk3beta were also increased in the other groups. Compared with the model group, the levels of HMI, LVMI, LVPW, IVS, and MFD were decreased respectively in all treatment groups (P<0.05); the contents of p-Akt and p-Gsk3beta were decreased in all treatment groups as well. There was no significant difference, however, among the low-, medium-, and high-dose tanshinone treatment groups and the valsartan treatment group (P>0.05).

CONCLUSIONTanshinone II A can prevent myocardial hypertrophy by its action on the protein kinase B (Akt) signaling pathway.

OBJECTIVETo investigate the inhibitory effect and mechanism against the growth of human gastric carcinoma cell line HS-746T by the combination of the survivin antisense oligonucleotide (ASODN) and P53 gene and its mechanism.

METHODSGastric carcinoma cell line HS-746T was treated by P53 gene and survivin antisense oligonucleotide was designed. There were four regimen groups treated by different agents:ASODN alone, P53 gene alone and the combination of ASODN and P53 gene, blank control. Cell proliferative ability and cell growth were determined by cells counting and MTT. The expression of survivin mRNA and protein was detected by RT-PCR and Western blot respectively. Cell apoptotic index was detected by TUNEL.

RESULTSASODN alone, P53 alone and the combination of ASODN and P53 could inhibit not only the growth of gastric carcinoma cell, but also down-regulate the survivin mRNA and protein expression. The inhibitory effect was stronger, and the apoptosis index was higher in the combined transfection group than those in the other two single transfection groups.

CONCLUSIONThe combination of survivin ASODN and P53 gene is more efficient to inhibit cell growth and induce apoptosis than that of agent alone.

Objective: In comparison with thrombus aspiration, to study the safety and effcacy of precise intracoronary retrograde thrombolysis during primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI).
Methods: A total of 123 consecutive patients with acute STEMI received primary PCI in our hospital from 2014-01 to 2015-12 were enrolled.The patients were randomly divided into 2 groups: RT group, the patients received precise intracoronary retrograde thrombolysis (RT),n=60 and TA group, the patients received thrombus aspiration (TA),n=63, among them, 3 patients with failed TA were excluded. Primary end points included occurrence rates of no-lfow after PCI and ST-segment resolution (STR)≥50% at (60-90) min after PCI; primary safety end points included occurrence rates of in-hospital stroke and TIMI-hemorrhage events.
Results:①Compared with TA group, RT group showed decreased no-lfow rate after PCI (1.7% vs 15.0%),P=0.008 and increased rate of STR≥50% after PCI (65.0% vs 45.0%),P=0.028, improved LVEF by echocardiography (50.7±8.6) % vs (46.7±8.3)%,P=0.011. The in-hospital MACE occurrence rate was similar between 2 groups,P>0.05.②No in-hospital stroke or TIMI-hemorrhage events occurred in neither group.
Conclusion: Intracoronary retrograde precise thrombolysis had the similar safety to thrombus aspiration during primary PCI in patients with acute STEMI, it may reduce no-relfow rate and improve left ventricular function after PCI.

BACKGROUNDNatural disasters have been frequent in recent years. Effective treatment of patients with cardiovascular disease following natural disasters is an unsolved problem. We aimed to develop a novel miniature mobile cardiac catheterization laboratory (Mini Mobile Cath Lab) to provide emergency interventional services for patients with critical cardiovascular disease following natural disasters. A feasibility study was performed by testing the Mini Mobile Cath Lab on dogs with ST-elevation myocardial infarction (STEMI) model in a hypothetical natural-disaster-stricken area.

METHODSThe Mini Mobile Cath Lab was transported to the hypothetical natural-disaster-stricken area by truck. Coronary angiography and primary percutaneous coronary intervention (PCI) were performed on six dogs with STEMI model. The transportation and transformation of the Mini Mobile Cath Lab were monitored and its functioning was evaluated through the results of animal experiments.

RESULTSThe Mini Mobile Cath Lab could be transported by truck at an average speed of 80 km/h on mountain roads during daytime in the winter, under conditions of light snow (-15°C to -20°C/-68°F to -59°F). The average time required to prepare the Mini Mobile Cath Lab after transportation, in a wetland area, was 30 minutes. Coronary angiography, and primary PCI were performed successfully.

CONCLUSIONThis preliminary feasibility study of the use of the Mini Mobile Cath Lab for emergency interventional treatment of dogs with STEMI indicated that it may perform well in the rescue of critical cardiovascular disease following natural disasters.
