Objective To observe the effect of coronary artery disease on QT dispersion (QTd). Methods The QTd and QTcd in 245 patients underwent percutaneous coronary angiography (CAG) were analyzed. It was evaluated The relations between the QTd and the degree of coronary stenosis and the number of disease vessels. Results The QTd and QTcd were significantly prolonged in patients with coronary artery stenosis than those in patients with normal coronary artery(P0.05). Conclusion There is no relation between the number of disease coronary artery and the QTd.

Objective To establish a desirable quantitative assay system to evaluate the correlation between surgical manipulation and micrometastasis in primary esophageal cancer patients.Methods 118 pe- ripheral blood samples from 40 esophageal cancer patients undergoing radical resection were collected before surgery(B-1),immediately after surgery(B0)and at the third day postoperatively(B+3).Based on real-time quantitative reverse transcription-PCR,carcinoembryonic antigen(CEA)mRNA gene was used in the detec- tion.12 patients with benign tumor and 13 healthy volunteers were collected as negative control groups.Re- sults The median of CEA mRNA copies at B-1,B0 and B+3 were 1592,13 314 and 6221 copies/ml blood, respectively.CEA mRNA expression levels were found to be significantly higher at both B0 and B+3 than that of B-1(P=0.0001 and 0.0209,respectively).No significant difference was found between B0 and B+3(P= 0.4396).Conclusion Surgical manipulation on esophageal cancer patients increases the probability of mi- crometastasis.Therefore,adjuvant therapy is needed during perioperative stage.

Near-infrared (NIR) was used as rapid analysis method to identify the sulfur fumigated Puerariae Lobatae Radix. NIR spectra of the cross-sectional and longitudinal selection of samples were acquired. Principal component analysis was conducted. The samples were randomly selected. The different pretreatment methods were compared. Discriminant models were established for every type of spectra to calculate the recognition rate. The orthogonal test and nonparametric test were used to test data normality. The result showed that absorbance values of different sections were different due to the different structure, and the raw spectra were analyzed by PCA method. The result founded that the cumulative contribution rate was arrived at 99.2% while the PC numbers were arrived at 3. The pretreatment method based on the MSC + 1D + Savitzky-Golay was the best to establish the model. For the 50 models constructed with cross-section and longitudinal spectra and total spectra, the recognition rate were (94.4 ± 0.66)%, (94.4 ± 0.66)%, (95.3 ± 0.65)%, respectively, and no difference was observed. The NIR method could be used to identify the sulfur fumigated Puerariae Lobatae Radix.

Objective To explore the effect of hepatocyte growth factor on peripheral nerve regeneration. Methods Sciatic nerve contusion injury was made by a custom-made clamp in Wistar rats,in which human hepatocyte growth factor expressed by adenoviral vector(Ad-HGF)was injected into the muscle around the injured nerve.The results of nerve regeneration were evaluated by sciatic nerve function index(SFI),muscle wet weight,neural electrophysiology and image analysis. Results Four weeks after sciatic nerve injury,the results of sciatic nerve function index(SFI),muscle wet weight,neural electrophysiology and image analysis showed better nerve regeneration in group injected with HGF than control group(P<0.05). Conclusion Hepatocyte growth factor can promote axon regeneration and functional recovery and is an effective neurotrophic factor for peripheral nerve regeneration after injury.

Objective To evaluate the factors influencing early diagnosis and prognosis in patients with pancreatic carcinoma.Methods The clinical data of 280 patients who had complete follow-up data with pancreatic carcinoma treated from January 2002 to January 2007 were reviewed retrospectively.The medical history and follow-up data were collected from all patients.Survival rate was calculated by the life table method and the Kaplan-Meier estimation.Log-rank test was used for univariate prognostic analysis and Cox regression was used for multivariate prognostic analysis.Results 91.8%of the patients were more than 40 years old and the peak age was 50~73 years old;the major presentations were abdominal pain and jaundice.Major imaging tests included B-ultrasound and CT,the sensitivity was 70.6%,95.3%,respectively;89.3%of patients had combined B-ultrasound and CT examination.The sensitivity of CA19-9 was 81.1%.The median survival time was(7.0±0.5)months.Overall survival rates at 1~5 year survival rates were 28%,9%,6%,2%,and 1%.Univariate analysis suggested that age>65 years old,CA19-9>mean value,TNM Ⅲ or Ⅳ stage,lymph nodes invasion,vascular invasion,and metastasis of two or more organs,non-surgical treatment,KPS score<60 points,weight loss≥5 kg were poor prognostic factors;Cox multivariate analysis showed that treatment modalities,age,TNM stage,KPS score and ascites were independent risk factors for dismal prognosis.Conclusions The age,ascites,tumor stage and treatment modalities affected the prognosis of patients with pancreatic cancer.Early diagnosis and treatment was important to improve the survival time of patients with pancreatic cancer.

To establish a molecular identification method for Bletillae Rhizoma, this paper extracted genome DNA from Bletillae Rhizoma and its adulterants. The sequences of rDNA ITS2 were sequenced after amplifying. Then multiple alignments of ITS2 were constructed phylogenetic tree with Neighbor Joining by MEGA 5. 1 and found out SNPs loci. The result showed that rDNA ITS2 region could identify Bletillae Rhizoma and its adulterants. There existed the SNPs loci, which could identify Bletilla striata and B. ochracea. Furthermore, we designed specific primers against the SNPs loci of B. striata and B. ochracea, then screened primers and optimized the PCR amplification conditions. Finally, the DNA of B. striata and B. ochracea were specifically amplified by BJ59-412F, BJ59-412R and HHBJ-225R. The length of amplification products were respectively about 350 bp and 520 bp that were effectively identified of B. striata and B. ochracea. While, the adulterants of Bletillae Rhizoma were no-reaction occurring. To sum up, the amplification conditions of the primers can identify B. striata, B. ochracea and their adulterants successfully at the same time. This method was easy, time-saving, and reliable, which can be used as a rapid method for molecular identification of Bletillae Rhizoma.
