Progress in Biochemistry and Biophysics 2009;36(11):1490-1494
A novel PCR-based mutagenesis method was reported, in which there is no need to purify megaprimers or design a special flanking primer. This method used one mutagenic primer and two sequencing primers (T_m≤58℃) as flanking primers. After first round PCR, 12.5 μl first PCR production was directly added into 50 μl second PCR system as template and megaprimer, and 10 rounds of asymmetrical PCR at high temperature of annealing (68 ℃ ) was to add in initiation of second PCR. This additional step greatly has increased the efficiency of mutagenesis via 600 bp or 800 bp long megaprimer. The results demonstrated that this method can achieve high fidelity, 97%~ 98% efficiency, high yield.

Objective To observe the clinical efficacy of fire acupuncture plus herbal medicine in treating acute gouty arthritis. Method Eighty-nine patients with acute gouty arthritis were randomized into a treatment group of 45 cases and a control group of 44 cases. The treatment group was intervened by fire acupuncture plus orally taking herbal medicine, while the control group was by oral administration of Diclofenac sodium and Allopurinol. The average pain score was observed before and after intervention, and the clinical efficacies were compared between the two groups.Result The total effective rate was 95.6% in the treatment group versus 81.8% in the control group, and the difference was statistically significant (P<0.05). The average pain score was significantly changed in both groups after intervention (P<0.01). After treatment, there was a significant difference in comparing the average pain score between the two groups (P<0.05).Conclusion Fire acupuncture plus herbal medicine is an effective approach in treating acute gouty arthritis.

Objective To detect serum protein spectrum in gastric cancer, screen the serum proteins related to gastric carcinoma and build auxiliary diagnosis model with SELDI-TOF-MS, Methods The serum proteomic fingerprints were detected by SELDI-TOF-MS and CM10 proteinchip. The sera came from 50 first visit gastric cancer patients who were diagnosed by pathological method and 16 healthy peo- ple. The data were analyzed by Biomarker Wizard Software and the proteomic fingerprint of gastric carcinoma model was developed by BPS (biomarker pattern software). Results Compared with the healthy people group, there were 34 significant different protein peaks in the gas- tric carcinoma group. And the diagnosis model composed with 6 proteins (M/Z values were 6016, 6744, 2822, 4474, 7892 and 3242) could classify the 2 groups correctly. In the test group, the sensitivity and specificity were 96% and 93.75% respectively, the accuracy was 95.45%. Conclusion SELDI-TOF-MS method show features such as microcontent, fast and high- resolution etc. It could be utilized to screen significant proteins and develop an auxiliary diagnosis model in gastric carcinoma, which may be used to diagnose this disease.

Objective To investigate the characteristics and risk factors of abdominal lymph node metastasis in thoracic esophageal squamous cell cancer.Methods The clinical data of 586 patients with thoracic esophageal cancer who underwent surgery via transabdominal and transthoracic approaches between June 2009 and June 2014 at the Sichuan Cancer Hospital were retrospectively analyzed.All the patients received resection of esophageal cancer and lymph node dissection, and the transabdominal right thoracic approach or cervico-thoracicabdominal triple incision was selected according to the condition of patients.No.18, 19, 20 lymph nodes were dissected seperately and No.16, 17 and lesser curvature lymph nodes were separated.All the specimens of lymph nodes were detected by regular pathological examination.Measurement data with normal distribution were presented as x ± s and count data were described as rate.Comparisons of rate between 2 specimens and among the multiple specimens were respectively analyzed using the chi-square test and partition of chi-squared.The multivariate analysis was done using the logistic regression.Results The number of lymph node dissected in 586 patients was 12 524 with an average number of 20 ± 11 per case, and the rate of lymph node metastasis was 55.63% (326/586).The number of mediastinal lymph node dissected was 7 012 with an average number of 12 ± 5 per case, and a rate of mediastinal lymph node metastasis was 40.96% (240/586).The number of abdominal lymph node dissected was 5 512 with an average number of 9 ± 8 per case, and a metastasis rate was 31.74% (186/586).The abdominal lymph node metastasis rate of the upper, middle and lower thoracic esophageal cancer were 13.73% (14/102), 31.51% (92/292) and 41.67% (80/192), respectively, showing a significant difference among the above 3 indexes (x2 =25.91, P < 0.05).The lymph node metastasis rate in No.16, 17, 18,19, 20 and lesser curvature lymph nodes were 12.80% (75/586), 16.89% (99/586), 1.71% (10/586),0.68% (4/586), 1.71% (10/586) and 2.05% (12/586), respectively, with a significant difference among the above 6 indexes (x2 =287.95, P < 0.05).The results of univariate analysis showed that the tumor location,surgical procedure, T stage, N stage, G stage, pathological stage and mediastinal lymph node metastasis were risk factors affecting abdominal lymph node metastasis of thoracic esophageal cancer (x2 =24.02, 23.97, 37.87,136.85, 38.79, 7.70, 154.27, P < 0.05).The tumor in the lower thoracic portion, N3 stage and stage Ⅳ were independent risk factors affecting abdominal lymph node metastasis of thoracic esophageal cancer in the multivariate analysis (RR =5.80, 2.36, 2.76, 95% confidence interval: 1.022-1.813, 1.317-3.950, 1.652-12.351, P < 0.05).Conclusions Abdominal lymph node metastasis is common in thoracic esophageal cancer in which No.16 and 17 lymph nodes predominate, and it is easy to occur in patients with lower thoracic esophageal cancer, and advanced N stage and pathological type.

Objective:To observe the clinical efficacy of skin needling plus heat-sensitive moxibustion in treating chronic facial paralysis. Methods:Sixty patients with chronic facial paralysis were divided into an observation group and an acupuncture group by using the random number table, 30 in each group. Patients in the observation group were given skin needling plus heat-sensitive moxibustion; while patients in the acupuncture group were given conventional acupuncture. Results:Three treatment courses later, the total effective rate was 93.3% in the observation group versus 86.7% in the control group, and the difference was statistically significant (P<0.05). Conclusion:Skin needling plus heat-sensitive moxibustion can produce a more significant efficacy than conventional acupuncture in treating chronic facial paralysis.
