The Medical Healthcare Service Center,located at the Youxian District,Mianyang City of Sichuan Province,successfully rescued the people affected by the Wenchuan earthquake and the Tangjiashan barrier lake with great help from the senior hospitals.We suggest that the community healthcare service center could play an important role in emergency response system.

Objective To explore the feasibility of artificial silastic framework(SF)in repair of large area of tracheal wall defects.Methods Twenty healthy adult dogs with tracheal defects for 2.5 cm?6.0 cm-3.0 cm?6.0cm were randomly and equally divided into experimental group(repaired with SF combined with sternohyoid fasciae)and control group(repaired with T-silastie tubule combined with sternohyoid fascial flap).After the operation,the animals were sacrificed at the 4th,8th,16th,24th, and 48th weeks respectively for harvesting the tracheae that were used for tracbeoscopically observing in- flammatory reaction of the repaired defect area and light microscopically observing epithelium healing on the repaired defect area.Results In the experiment group,the repaired trachea was smooth,without proliferation of granulation;and at the 8th week,the repaired defect area was covered with epithelial cells,with good functional recovery of respiration,phonation and deglutition.In the control group,there was obvious proliferation of granulation on the tracheal surface near anterior and posterior ends of T-silas tic tubule.The animals were under asphyxia to die with extraction of T-silastic tubule.Conclusions SF has excellent tracheal skeletal function.In the meantime,SF combined with sternohyoid fasciae is a simple but effective method for repair of large area of tracheal wall defects.

OBJECTIVETo explore the mechanisms of Qianjing Decoction in the treatment of oligoasthenospermia (OAS).

METHODSWe randomly divided 100 SPF male rats into five groups of equal number: normal, model, Huangjingzanyu, levocarnitine, and Qiangjing. OAS models were established in the animals followed by intragastrical administration of normal saline, ornidazole, Huangjingzanyu Capsules (200 mg per kg body weight per day), levocarnitine (100 mg per kg body weight per day), and Qianjing Decoction (10 g per kg body weight per day), respectively, qd, for 4 successive weeks. Then, we detected the concentration and motility of the epididymal sperm, obtained the contents of superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GSH-Px), lactate dehydrogenase (LDH), α-glucosidase, and fructose in the epididymis, and determined the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and succinate dehydrogenase (SDH) in the epididymal tissue of the rats by real-time PCR.

RESULTSThe concentration and motility of the epididymal sperm in the model, Huangjingzanyu, levocarnitine, and Qianging groups were (35.34 ± 4.22) x 10(6)/ml and (40.04 ± 7.05)%, (48.12 ± 5.56) x 10(6)/ml and (62.46 ± 7.12)%, (47.14 ± 4.87) x 10(6)/ml and (63.23 ± 6.34)%, and (50.25 ± 5.08) x 10(6)/ml and (66.34 ± 7.58)%, respectively, all significantly lower than in the normal group ([53.05 ± 4.55] x 10(6)/ml and [70.20 ± 8.54]%) (P < 0.05), but remarkably higher in the Huangjingzanyu, levocarnitine, and Qiangjing groups than in the model rats (P < 0.05). Compared with the thinned epididymal lumen walls, decreased sperm count, and disorderly and loose arrangement of the lumens in the OAS models, the rats in the Huangjingzanyu, levocarnitine, and Qiangjing groups showed evidently thicker epididymal lumen walls, with the lumens full of sperm cells and arranged regularly and compactly, similar to those of the normal rats. The levels of SOD and GSH-Px were significantly lower but that of MDA markedly higher in the model rats ([84.12 ± 23.25], [10.56 ± 3.02], and [14.04 ± 2.06] nmol/mg) than in the normal group ([110.04 ± 19.56], [17.25 ± 3.56], and [8.87 ± 1.35] nmol/mg) (P < 0.05), while the former two indexes remarkably higher and the latter one significantly lower in the animals treated with Qiangjing Decoction ([120.56 ± 23.68], [16.34 ± 3.12], and [8.45 ± 1.56] nmol/mg), Huangjingzanyu Capsules ([115.34 ± 21.35], [15.23 ± 3.67], and [8.33 ± 1.54] nmol/mg), and levocarnitine ([116.67 ± 22.67], [15.35 ± 3.45], and [8.05 ± 1.78] nmol/mg) than in the models (P < 0.05). The levels of fructose, LDH and α-glucosidase were decreased markedly in the OAS models ([100.22 ± 12.12] mg/[ ml x g], [322 ± 46.13] U/[ ml x g], and [10.48 ± 2.33] U/[ml x g]) as compared with the normal rats ([128.12 ± 13.45] mg/[ml x g], [428 ± 35.12] U/[ml x g], and [15.34 ± 3.12] U/[ ml x g]) (P < 0.05), remarkably higher in the rats treated with Qiangjing ([130.23 ± 13.67] mg/[ml x g] [455 ± 51.50] U/[ml x g], and [18.56 ± 4.67] U/[ml x g]), Huangjingzanyu ([124.16 ± 14.02] mg/[ml x g], [ 419 ± 43.14] U/[ml x g], and [17.64 ± 4.08] U/[ml x g]), and levocarnitine ([123.34 ± 14.02] mg/[ml x g], [430 ± 31.80] U/ [ml x g], and [16.85 ± 5.55] U/[ml x g]) than in the models (P < 0.05). The Nrf2 mRNA expression was significantly reduced in the models as compared with the normal rats (P < 0.05) but remarkably increased in the Huangingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05). The SDH mRNA expression was significantly lower in the model than in the normal rats (P < 0.05) but markedly elevated in the Huangjingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05), remarkably higher in the Qiangjing than in the Huangjingzanyu group (P < 0.05).

CONCLUSIONOrnidazole induces OAS in rats, which is closely associated with excessive oxidation and energy metabolism dysfunction. Qiangjing Decoction can improve and even reverse ornidazole-induced OAS in rats as well as improve the ultrastructure of their testicular and epididymal tissues. Antioxidation and improvement of energy metabolism are probably the action mechanisms of Qiangjing Decoction in the treatment of OAS.

BACKGROUNDChronic liver disease causes aberrant formation of fibrous tissue that impedes normal liver function, ultimately resulting in liver cirrhosis. Iron uptake can occur within the hepatic parenchyma or within the various nodules that form in a cirrhotic liver, termed siderotic nodules (SN). We aimed to investigate the diagnostic performance of susceptibility weighted imaging (SWI) for detection of SN in patients with liver cirrhosis, and to evaluate the potential of SN numbers for assessing the degree of hepatic iron deposition, liver function, and liver fibrosis stage.

METHODSNinety-one patients with chronic liver cirrhosis, who underwent megnetic resonance imagine (MRI) scanning in our department between November 2010 and April 2011, were included in the study. A 3.0T MRI scanner was used to acquire T1WI, T2WI, T2WI, and SWI images. The number of nodules, signal intensity ratio (SIR), and contrast noise ratio (CNR) were recorded and analyzed by chi-square and ANOVA statistical tests. Correlation analysis was performed to evaluate the correlations between the number of SN and Child-Pugh classification, ferritin and hyaluronic acid levels.

RESULTSThe sensitivity of SWI, T1WI, T2WI, and T2 WI for detecting SN was 62.5%, 12.1%, 24.2% and 41.8%, respectively. SWI detected significantly more nodules than routine T1WI, T2WI, and T2 WI procedures (P < 0.05). The SIR was the lowest in SWI (0.361 ± 0.209), as compared to T1WI (0.852 ± 0.163), T2WI (0.584 ± 0.172), and T2 WI (0.497 ± 0.196). The CNR was the highest in SWI (13.932 ± 5.637), as compared to T1WI (9.147 ± 5.785), T2WI (9.771 ± 5.490), and T2 WI (11.491 ± 4.573). The correlation coefficients of the number of SN with ferritin, Child-Pugh classification, and hyaluronic acid levels were 0.672, -0.055, and 0.163, respectively.

CONCLUSIONSThe sensitivity and contrast of SWI for detecting SN in patients with liver cirrhosis are higher than conventional MRI. The number of SN can help to assess the degree of iron deposition in patients with liver cirrhosis.

Proteomics plays important roles in Chinese medicine research at post-genomics era. Its research idea and methods are beneficial for elucidating some elemental features of Chinese medicine. At present, Chinese medicine proteomic studies are mainly focusing on the syndromatology and medical herbal pharmacology. However, there are still some problems, the most important matter was that most of the results were merely the superficial delineations. Further research should put emphasize on the unremitting and penetrating study of proteomics, molecular biology and bioinformatics integrally for illuminating Chinese medicine theory deeply to promote the modernization of Chinese medicine research.

OBJECTIVETo study the apoptosis inducing effects of Hechanpian (HCP) on human lung adenocarcinoma A549 cells.

METHODSHCP containing rat serum was prepared and applied on A549 cells. The cell growth inhibition rate was tested by MTT assay; the effect of HCP on cell apoptosis was observed with Propidium iodide (PI) staining and flow cytometry analysis; the mRNA expression of epidermal growth factor receptor (EGFR) was detected through RT-PCR.

RESULTSThe growth of A549 cells was obviously inhibited after being treated by HCP containing serum, and the cells presented an apoptotic change. The cell apoptosis rate after treated by serum containing 10% and 20% HCP was 20.5% and 33.2%, respectively, significantly higher than that in the control (6.1% in cells didn't treated with HCP, P < 0.05). Compared with control, EGFR mRNA expression in HCP treated cells was significantly lower (P < 0.05).

CONCLUSIONHCP has apoptosis inducing effect on A549 cell, and its molecular mechanism is probably correlated with the inhibition of EGFR gene transcription.

Objective The left ventricular myocardial strain of acute myocardial infarction on cardiac magnetic resonance cine imaging was measured by feature tracking technique. The relationship between left ventricular myocardial strain and the transmural extent of Myocardial Infarction was evaluated. Methods 74 patients with acute ST segment elevation myocardial infarction were included. All theses patients received primary PCI within 12 hours. After 2 to 5 days. ECG gated steady-state free precession sequences were collected. Gadolinium contrast enhanced imaging was performed on short axis. 20 patients repeated same scan after 3 to 5 months. TomTec 2D CPA and Segment software were used to analyze the images. The peak values of the regional myocardial strain indexes. The transmural extent of myocardial infarction of segment in left ventricular was measured. Results There was no significant difference of longitudinal strain in non-infarction,non-transmural infarction and transmural infarction segments at the basal and middle segments. The circumferential strain peak and the radial strain peak of non-transmural infarction segments were lower than those of the non-infarction segments. The circumferential strain of transmural infarction segments were the lowest(basal level:-14.24％±9.05％,P<0.05;middle level:-12.71％±8.92％,P<0.05;apical level:-13.81％±11.13％, P<0.05). GLS was improved while LVDd was increased when compared the acute phase of myocardial infarction to that of 3-5 months after primary PCI. The circumferential strain and longitudinal strain of the non-transmural infarction segments was improved. The circumferential strain and radial strain of the transmural infarction segments 3-5 months later was improved as compared to the acute phase. Conclusions There was differences in myocardial strain in non-infarction,non-transmural infarction and transmural infarction segments from patients with acute ST segment elevation myocardial infarction who had accepted primary PCI. The circumferential strain and longitudinal strain of the non-transmural infarction segments were improved after 3-5 months. The circumferential strain and radial strain of the transmural infarction segments after 3-5 months was improved as compared to the acute phase. Cardiac Magnetic resonance could combine feature tracking technique with gadolinium contrast delayed enhancement technique,giving both function and tissue characteristic evaluation to the myocardial damages after acute myocardial infarction.

OBJECTIVETo determine differences in adherence to secondary prevention guidelines (pharmacological interventions) among coronary heart disease (CHD) patients between a Chinese medicine (CM) hospital and a general hospital in a Chinese city.

METHODSMedical records of 200 patients consecutively discharged from the CM hospital and the general hospital for CHD were reviewed to determine the proportions of eligible patients who received antiplatelet agents, β-blockers, angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) and statins at discharge. The effects of patient characteristics and hospital type on the use of these medicines were estimated using logistic regression models.

RESULTSPatients discharged from the CM hospitals were older; more likely females; had greater history of hyperlipidemia, cerebrovascular diseases and less smoker (P<0.01 or P<0.05). They were less likely to receive coronary angiography and percutaneous coronary intervention, and had a longer length of stay than those discharged from the general hospital (P<0.01 or P<0.05). There were no significant differences in antiplatelet agents (96% vs. 100%, P=0.121) or statins (97.9% vs. 100%, P=0.149) use between the CM hospital and the general hospital. In multivariable analyses that adjusted for patient characteristics and hospital type, there was no significant difference in use of β-blockers between the CM hospital and the general hospital. In contrast, patients discharged from the CM hospital were less likely to receive ACE inhibitors/ARBs compared with those discharged from the general hospital (odds ratio: 0.3, 95% confidence interval: 0.105-0.854).

CONCLUSIONIn this study, the CM hospital provides the same quality of care in CHD for prescribing evidence-based medications at discharge compared with another general hospital except for ACE inhibitors/ARBs use.
