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.

PURPOSE To sutdy the effects of dibutyl pathalate (DBP) on the proliferation and apoptosis of leukemic cells from patients suffering from acute leukemia. METHODS The cell culture in vitro was used to study the effect of DBP on the proliferation of leukemic cells, while agrose gel electrophoresis of DNA fragments was used to study the effect of DBP on apoptosis of leukemic cells. RESULTS DBP could inhibit the proliferation of leukemic cells got from patients suffering from acute leukemia in vitro. The percentage of inhibition were 24.24% and 36.33% respectively when leukemic cells were exposed to 50?g/ml and 200?g/ml DBP for 24 hours. Leukemic cells from acute myelogenous leukemia were more susceptive to DBP than those from acute lymphocytic leukemia. DBP also induced the leukemic cells from patients to die via apoptosis and showed typical "ladder" of DNA fragments for apoptotic cells in agrose gel electrophoresis. CONCLUSION DBP could clear the leukemic cells in bone marrows of patients suffering from acute leukemia by suppressing the growth of leukemic cells and inducing them to die via apoptosis.

AlM: To observe the influence ofphacoemulsification on corneal endothelial cell in patients with the different level of HbA1c.METHODS:With case-control study, 164 eyes from 115 cataract patients were divided into four groups according to the preoperative HbA1c level. Control group A: 43 eyes from 30 cases without diabetes ( HbA1c≤6. 5%). Diabetes groups:group B was consisted of 38 eyes from 26 cases(HbA1c≤6. 5%), 40 eyes of 28 case was in group C (6. 5% 8. 0%). Corneal endothelial microscopy was used to detect the parameters like endothelial cell density ( CD ) , coefficient of variation ( CV ) , percentage of regular hexagonal cells (6A) between pre-operation and post-operation at 1d, 1, 2wk, 1mo. The results were analyzed.RESULTS: The endothelial cell density, CV and 6A cell had no significant difference in four groups before treatment (P>0. 05). The CD and 6A were decreased and CV was increased in all groups after operation of 1d, 1, 2wk and 1mo. The difference was statistically significant (P< 0. 05). There were statistical differences of 6A and CV in diabetes groups compared with control group ( P<0. 05). The decreasing of CD between group A and group B had no difference (P>0. 05). There were statistical differences of CD in group C and group D compared with group A (P<0. 05). There were statistical differences of CD, 6A and CV within diabetes groups (P<0. 05). CONCLUSlON: Cataract phacoemulsification had certain degree damage on corneal endothelial cell. Corneal endothelial appeared the minimal injury when the postoperative HbA1c≤6. 5%. For diabetic cataract patients, the higher HbA1c before, the heavier damaged after the surgery.

ObjectiveBy observing and comparing the effect of wheat-sized moxibustion on the quality of life and interleukin (IL)-10 expression in stageⅢ~Ⅳtumor patients of two different traditional Chinese medicine (TCM) patterns by using QLQ-C30 questionnaire, to see whether wheat-sized moxibustion can improve the quality of life, regulate oncology-related immune system, and enhance the survival rate of the stageⅢ~Ⅳtumor patients.MethodForty-two tumor patients were randomized into a treatment group and a control group and were differentiated into TCM patterns. The treatment group was intervened by conventional Chinese and Western medicine plus 2 weeks of wheat-sized moxibustion. QLQ-C30 questionnaire was adopted for evaluation before and after treatment, and peripheral blood was drawn to detect the expression of IL-10.ResultWheat-sized moxibustion improved the quality of life, especially fatigueand poor appetite; the expression of IL-10 dropped after wheat-sized moxibustion.Conclusion Wheat-sized moxibustion can improve the quality of life of the tumor patients and down-regulate the expression of IL-10.

A prospective study was conducted for 91 cases of fever patients after neurosurgical procedures during the period of January-December 2013.They were divided into non-infection (n =42) and infection (n =49) groups according to whether there was infection complication.And another 51 nonsurgical hospitalized patients without fever or infection were selected as control group.The levels of procalcitonin (PCT),C-reactive protein (CRP) and white blood cell (WBC) were detected respectively.Statistical analysis showed that the level of PCT had no significant difference between non-infection and control groups (P ＞ 0.05).However,it was markedly elevated in infection group than non-infection group (P ＜ 0.01).The level of CRP was significantly different between non-infection and control groups (P ＜ 0.01).And it was the same between infection and non-infection groups.The level of WBC had significant difference between non-infection and control groups (P ＜ 0.05) and infection and non-infection groups (P ＜ 0.01).The receiver operating characteristic (ROC) curve showed that either sensitivity or specificity of PCT was the highest.Compared with CRP and WBC,PCT may identify more accurately the causes of fever after neurosurgical procedures.

Objective To determine the optimized fractionated radiation schedule by comparing the dose-response relationship between different fractionated radiation schedules with a total dose of 40 Gy or 60 Gy in subclinical breast tumor.Methods Balb/c nude mice bearing subclinical human breast cancer (injected subcutaneously into the hind legs with 1.5 × 105 or 3.1 × 105 exponentially growing MCF-7 cells) were assigned randomly to blank control group (without radiation),conventionally fractionated radiation group (200 cGy,once daily,10 times/week),hyperfractionated radiation group (160 cGy,twice daily with an interval of 6 h,5 times/week),first hypofractionated radiation group (300 cGy,once daily,5 times/ week),and second hypofractionated radiation group (400 cGy,once every other day,3 times/week) ;the total dose was 40 Gy or 60 Gy.The measurement indices were tumor formation rate,short-term tumor control rate,long-term tumor control rate,the time of tumor recurrence,and the maximum diameter of the bottom of tumor.The observation lasted 24 weeks.Data were compared between these groups by chi-square test.Results With a total dose of 40 Gy (the number of injected cells was 1.5 × 105,the tumor formation rate of the blank control group was 2/8),hyperfractionated radiation was the optimized schedule.With a total dose of 60 Gy (the number of injected cells was 3.1 × 105,the tumor formation rate of the blank control group was 11/11),the first hypofractionated radiation (300 cGy,once daily,5 times/week) was the optimized schedule (P =0.001);the short-term and long-term tumor control rates of the conventionally fractionated radiation group,hyperfractionated radiation group,second hypofractionated radiation group,and first hypofractionated radiation group were 0/0 (tumor formation rates:8/8 and 8/8),50％/25％ (tumor formation rates:4/8 and 6/8),25 ％/25 ％ (tumor formation rates:6/8 and 6/8)),and 67 ％/67 ％ (tumor formation rates:4/12 and 4/12),respectively.Conclusions The optimized fractionated radiation schedule for subclinical breast cancer and its total dose vary with the number of injected tumor cells.When the tumor formation rate is 100％,hypofractionated radiation (300 cGy,once daily,5 times/week) is the optimized schedule in terms of long-term tumor control.

ObjectiveTo investigate the current situation of immunophenotyping of acute leukemia by flow cytometry in China (except Taiwan, Hongkong and Macau), and to provide theoretical evidence for the formulation of guidelines of immunophenotyping of leukemia by flow cytometry.MethodsThe Chinese Hospital Knowledge Database(CHKD) was used to retrieve the1994-2009 published papers on immunophenotyping of acute leukemia by flow cytometry.All of 380 retrieved papers were analyzed by the GraphPad Prism 4. ResultsThe number of published papers in China increased yearly and changed gradually from large cities to small and medium-sized cities in local distribution. The most often reported area was Beijing, followed by Jiangsu and Guangdong. In specimen processing, the ratios of using mononuclear cell labling method and whole blood labling-lysing-washing method were 34.2 ％ (113/330) and 65.8 ％ (217/330) respectively. The ratios of using single color, two color, three color and four color labling method were 15.4 ％ (53/344), 13.7 ％ (47/344), 54.1％ (186/344) and 16.3 ％ (56/344), respectively. The number of fluorescent antibodies was used from less than 10 to more than 20.Most of them were between 11 to 16,which was 48.6 ％ (167/344) of total number of published papers. In data acquisition and analysis, the ratios of using FSC/SSC gating and CD45/SSC gating were 34.2 ％ (113/330) and 65.8 ％ (217/330), respectively. There were some differences in the positive criteria of lymphatic and myeloid and cytoplasm antigens.The main positive criteria of lymphatic, myeloid antigen was ≥20 ％, which was 64.8 ％ (223/344) and 95.4 ％ (328/344) . The main positive criteria of cytoplasm antigen was ≥ 10 ％, which accounted for 61.2 ％ (156/255). Conclusion A common view has been reached in specimen processing,gating method,data acquisition and analysis in immunophenotyping of acute leukemia by flow cytometry. But there were still some difference in the number of fluorescent antibodies, panels and evaluation of positive criteria of antigens.
