Objective:To explore improving effect of Danqi soft capsule on hemorheology in patients with coronary heart disease (CHD) and its myocardial protection effect .Methods:A total of 84 CHD patients treated in our hos‐pital from Dec 2013 to Dec 2014 were enrolled .They were randomly divided into routine treatment group (n=42) and combined treatment group (n=42 ,received Danqi soft capsule therapy based on routine treatment group ) .He‐morheological indexes ,ECG and inflammatory factor levels [C reactive protein (CRP) ,tumor necrosis factor α(TNF‐α)] were measured and compared between two groups before and after treatment .Results:Compared with before treatment , above hemorheological indexes significantly reduced in both groups after treatment ( P< 0.05 all) ,compared with routine treatment group ,there were significant reductions in high shear whole blood viscosity [ (5.12 ± 0.73) mPa/s vs .(4.47 ± 0.86) mPa/s] ,low shear whole blood viscosity [ (7.36 ± 1.32) mPa/s vs .(6.21 ± 1.03) mPa/s] ,plasma viscosity [ (1.47 ± 0.31) mPa/s vs .(1.31 ± 0.25) mPa/s] ,erythrocyte aggregation index [ (3.53 ± 0.45) vs .(2.93 ± 0.26)] and fibrinogen level [ (2.95 ± 0.28) g/L vs .(2.08 ± 0.24) g/L] in combined treatment group , P< 0.05 all .Total effective rate on ECG in combined treatment group was significantly higher than that of routine treatment group (85.71% vs .57.14% ,P<0.05) .Compared with before treatment ,CRP and TNF‐αlevels significantly reduced in both groups after treatment ( P<0.05 all) ,compared with routine treatment group ,there were significant reductions in levels of CRP [ (6.52 ± 1.61) mg/L vs .(5.18 ± 1.25) mg/L] and TNF‐α [ (283.28 ± 18.28) pg/ml vs .(245.08 ± 12.24) pg/ml] in combined treatment group , P<0.05 all .Conclusion:Danqi soft capsule combined routine treatment can significantly improve hemorheology and reduce related inflamma‐tory factor levels ,possess myocardial protection effect in CHD patients ,which is worth extending .

Objective To study the expression of SARS-associated coronavirus nucleocapsid(N) gene in Pichia pastoris and to obtain recombinant N protein with good biological activity.Methods The gene encoding the full N protein of SARS-CoV was amplified by PCR and cloned into Pichia pastoris expression vector pPICZA.The recombinant expression plasmid pPICZA/N was transformed into X-33,KM71H and GS115. The positive insert transformants were screened,cultured and induced by methanol.The recombinant protein was further purified with Ni affinity chromatography.Antigen activity was detected with anti-N monoclonal antibody,polyclonal antibody and sera from SRAS patients.Results SDS-PAGE and immunological analysis demonstrated that only Pichia pastoris transformants KM71H/pPICZA/N and X-33/pPICZA/N expressed Mr 70 000 fusion protein with special antigenicity.Conclusion SARS-CoV N protein expression in Pichia pastoris has been achieved,establishing the basis for further study of biological and immunological function of N antigen.

Pancreatic cancer is a common malignant neoplasm of the pancreas with an extremely high mortality.Currently,the early diagno-sis of pancreatic cancer is still not ideal.Attention should be paid to some clinical warning symptoms,such as unexplained abdominal and back pain,jaundice,and unexpected diabetes.Additionally,the combined use of CA19-9,CEA,and other tumor markers,the attention to biochemical indicators,the detection of mutation in KAI1 or p53 gene,and the exploration of the value of miRNA in clinical diagnosis are of great significance.On the other hand,ultrasound,CT,MRCP,ERCP,PET-CT,and other imaging methods,as well as effective col-lection of cytology specimens,should be performed.Thus,there is hope for the early diagnosis of pancreatic cancer.

Left atrial volume index (LAVI) is related to systolic and diastolic function of heart .It can reflect the se‐verity of left atrial dilation and heart failure (HF) ,and is a powerful index predicting poor prognosis of HF .This article made a review on the relationship among cardiac function ,prognosis and LAVI in HF patients ,and the diag‐nostic value of LAVI for HF patients .

To support the ongoing health reform in China,Chongqing municipal government made the decision in 2008 "Building Healthy Chongqing" ,and pinpointed for the first time regional development as a key goal.In line with this situation,the hospital proposed such hypothesis changes as from "disease hypothesis to "health hypothesis",from "illness oriented" to "capability oriented",and from "shaping development" to "adaptive development",as well as from one-sided efforts of medical staff to minimize casualty to joint efforts with patients to safeguard life and health.Focusing on these four strategic shifts,the hospital works in developing its "technical attraction,service capacity,innovation capacity,and emergency assurance capability,and management soft power",aiming at building a sustainable hospital in its development.

Objective To explore the treatment approach to severe l ower extremity trauma. Methods A retrospective study was ca rried out in 42 cases with severe lower extremity trauma from 1989 to 1999. Mang led extremity severity score (MESS) was 6.24?1.45 in all the cases, among which were 34 cases with MESS

Objective To observe the effects of repeated low and high-frequency transcranial magnetic stimulation (rTMS) on neuropathic pain and the expression of specific activation markers of astrocytes and glial fibrillary acidic protein (GFAP) in the lumbar spinal cord.Methods Twenty-eight male Sprague-Dawley rats were randomly divided into a sham-operated group,a sham-rTMS group,a 1 Hz group and a 20 Hz group,with 7 in each group.The rats in the sham-operated group had their sciatic nerve exposed without ligation,while the other groups underwent sciatic nerve ligation to induce neuropathic pain.Three days after the operation,rTMS was applied to the primary motor cortex (M1) contralateral to the pain once a day for 10 consecutive days.Pain-related behavior and thermal pain response were tested before the operation and before and after the course of rTMS therapy.The expression of GFAP in the lumbar spinal cord was examined.Results All of the rats which underwent sciatic nerve ligation showed pain-related behavior and significantly decreasing thermal pain latency compared with the sham-operated group.After the rTMS therapy the thermal hyperalgia was significantly attenuated in the 20 Hz group but not in the 1 Hz group compared with the sham-rTMS group.The expression of GFAP in the dorsal horn of the lumbar spinal cord ipsilateral to the neuropathic pain was significantly increased in the sham-rTMS group and the 1 Hz group compared with the sham-operated group.Compared with the sham-rTMS group,GFAP levels were significantly lower in the 20 Hz group but not in the 1 Hz group.The pain relief in the 20 Hz group was negatively related to the expression of GFAP.Conclusions Neuropathic pain induced by peripheral nerve injury is associated with increased activity and proliferation of astrocytes in the dorsal horns of the spinal cord.High-frequency rTMS can relieve neuropathic pain through inhibiting the activity and proliferation of astrocytes in the dorsal horns,but low-frequency rTMS has no clinically significant effect.

Long non-coding RNAs ( lncRNAs) are a class of RNA molecules which are unable to codify proteins. They express abnormally in tumor cells including prostate cancer cells and play a significant role in development of tumor. Some lncRNAs have been proven to affect physiological processes of prostate cells and act as tumor suppressor or activator and could be regulated through several methods. Thus, lncRNAs have the potential to be therapeutic targets of prostate cancer. This review introduces expressed abnormally ln-cRNAs in prostate cancer and their functions and mechanisms in prostate cancer.

Objective To evaluate the difference between gallbladder polys,gallbladder adenomas and gallbladder cancer by sonography.Methods The imaging features were analysed including 571 patients with gallbladder polys,30 with gallbladder adenomas,109 with gallbladder cancer.Results The lesion diameter,echogram,color signals,maximum velocity(Vmax) and the resistive index(RI) were difference between Polys,Adenomas and cancers of gallbladder.When RI withinlesions lower than 0.65 was adopted as diagnostic criteria of gallbladder cancer,the specificity of the ultra-sound in diagnosis of gallbladder cancer were respectively.Conclusion Color Doppler flow imaging was useful in the differential diagnosis of gallbladder polypoid lesions in combination with gray-scale sonography.
