1.Gene polymorphism and physical constitution theory: starting point of exploring syndromes of lung cancer.
Journal of Integrative Medicine 2010;8(1):15-9
Physical constitution theory is an important part of traditional Chinese medicine theory. Physical constitution is associated with the incidence, development and prognosis of diseases. Gene polymorphism is a result of the interaction between internal and external environments during the human evolution, and it is the reason for differences in biological characteristics and disease susceptibility of individuals. Current status of the research on physical constitution theory, lung cancer syndromes and gene polymorphism are summarized in this paper. Exploring lung cancer syndromes from the point of view of gene polymorphism may reveal the scientific connotation of lung cancer syndromes, and provide new evidence and method for diagnosis of lung cancer.

Chinese Journal of Clinical Oncology 2009;36(24):1394-1397
Objective: To study the influence of clinicopathologic factors on the recurrent pattern of colorectal cancer after radical treatment. Methods: There were 464 consecutive patients with colorectal cancer treated with radical surgery between January 1998 and December 2002 in our hospital. The clinicopathologic features of 90 patients with relapse of colorectal cancer after radical surgery were analyzed. According to the interval between radical surgery and recurrence, these 90 patients were divided into subgroups, the early recurrent group (within 30 months after surgery) and the late recurrent group (more than 30 months after surgery). Chi-square test was used for univariate analysis, and the Logistic regression model was performed for multivariate analysis. Result: There were 78 (86%) patients in the early recurrent group and 12 (14%) patients in the late recurrent group. The median time of recurrence was 17.4 months. The median recurrent time in stage I patients was 35.1 months, 13.6 months in stage II patients, and 12.9 months in stage III patients, respectively. Univariate analysis showed that the depth of penetration, the number of positive lymph nodes, and the gross appearance of tumor were predictors for early recurrence. Multivariate analysis revealed that the depth of penetration (T category) of the primary tumor significantly predicted for early recurrence (P= 0.049). Conclusion: A great proportion of recurrence in patients with colorectal cancer occurred within 30 months after radical treatment, but the late recurrence which occurs at more than 30 months after radical surgery should not be neglected. Patients with different patterns of recurrence had different intervals between radical surgery and recurrence. DM (distant metastasis) occurs earlier than LR (local recurrence). The depth of penetration of the primary tumor is an independent predictor for early recurrence of colorectal cancer patients after radical surgery.

Objectives:To observe the role of nutritional support in patients after liver transplantation. Methods:Nutritional support was used in three patients after orthotopic liver transplantation(OLT).Total parenteral nutrition(TPN) was administered since the second day after the operation,the combination of enteral nutrition(EN) and parenteral nutrition(PN) was followed and then total enteral nutrition(TEN) was adopted.After that,oral intake of food was restored. Results:Postoperative patients were restored well. Conclusions:The supply of nutrition for patients after liver transplantation should be TPN→PN+EN→TEN,and then gradually increased.Once the gastroenteric functions of patients recover it is advisable to start EN as soon as possible.

Objective To investigate the effectiveness and methodology of percutaneous transluminal septal myocardial ablation (PTSMA). for hypertrophic obstructive cardiomyopathy (HOCM). Methods PTSMA with Sigwart's Method were performed in 57 patients with symptomatic HOCM from September 1999 to January 2005. Improvements were made about pressure monitoring, echocardiography guiding, the ablation procedure and the evaluation criteria of the operation. Results About 0.6-9.0 mL of absolute alcohol were consumed during PTSMA in each patient with 1-5 target septal branchs ablated per case. The resting and provoked left ventricular outflow tract pressure gradient monitored by catheter was reduced over 50% compared with preoperation level in all 57 cases. Two out of four cases with ECT exam had septal myocardial radioactive absence. During the follow-up of 2 weeks to 5 years, the clinical symptoms such as syncope, diziness, angina, palpitation and dyspnea, disappeared or were relieved in 54 cases compared with preoperation status. Two cases regained the above symptoms not long after the operation. One patient showed improvement in clinical symptoms and echocardiographic examination in 6 monthes, but she died of dilated congestive cardiomyopathy at 18 monthes after PTSMA. Follow-up echocardiographic examination was completed in 43 cases at 6 monthes and in 34 cases at 12 monthes after PTSMA. Further improvement was shown on UCG compared with 2 weeks after the operation. Some patients had transient or nonsustained ventricular tachycardia and atrioventricular block. Anteroseptal myocardial infarction was observed in 4 patients and 1 of them was accompanied by inferior myocardial infarction. Conclusion Percutaneous transluminal septal myocardial ablation for hypertrophic obstructive cardiomyopathy is safe and effective. Improvements have to be made for more satisfactory results of PTSMA.

Objective To investigate the efficacy of heparin plus low-dose aspirin on pregnant women with primary antiphospholipid syndrome(APS). Methods Three hundred and twenty women with unexplained pregnant failure were reviewed and anticardiolipin (aCL) immunoglobulin antibody G and M were tested. Heparin plus low-dose aspirin was given to 36 women with positive results. Results One fetal death and one embryo loss occured. The live birth rate was 94.4%(34/36) and the mean gestational week was (35.7?3.2) wks. The average birth weight was (2960?458) g which was significantly higher than the normal pregnancies (2684?324)g ( P

Daxx is found in the nucleus where it localizes to PML oncogenic domains (PODs). Its multiple domains can interact proteins involved in transcriptional regulation and apoptotic signal transduction. In addition, Daxx is associated with viral infection、tumorigenesis and embryonic development.

Objective To explore the impact of advanced glycation end-products ( AGEs) on matrix metalloproteinase 2 ( MMP-2) expression in cultivated INS-1 cells. Method INS-1 cells were cultivated and MMP-2 expression was analyzed. Glycated serum was prepared for incubating with INS-1 cell. Reactive oxygen species (ROS) was detected by flow cytometry. The intracelluar MMP-2 expression was analyzed by RT-PCR, realtime PCR and Western blot. The MMP-2 cDNA was expressed in cultivated INS-1 cells. Result The level of ROS treated with AGEs was significantly higher than that in the control( P<0.05 ) , and the levels of MMP-2 and its protein expressions turned out as well( P<0. 05). Conclusion The results suggest that MMP-2 was expressed in INS-1 cells. Increased MMP-2 expression in ?cells may be induced by AGEs, suggesting that MMP-2 might play an important role in oxidative stress-mediated islet injury.
