1.A study of condylar growth change with implants in individuals aged from 7.5 to 15.5
Journal of Practical Stomatology 2001;0(01):-
Objective: To annually quantify the condylar growth from 7.5 to 15.5 years and identify the growth direction of condyle during the same period of time.Methods: The sample was obtained from Mathew's implant study with longitudinal cephalometric records of 13 untreated Class I subjects (8 Females, 5 Males). The cephalograms were taken annually from 7.5 to 15.5 years old. Reference lines were constructed based on three implants in mandibular corpus and linear and angular measurements performed. Results:It was found that the greatest amount of bone apposition at points of condylion and superior condylion occurred during the ages of 11.5 years to 12.5 years with the average value of (3.61?2.58) mm and (3.28?2.17) mm, respectively. The largest amount of bone addition at point of posterior condylion occurred much earlier between 8.5-9.5 years old, with average value of (1.92?1.16) mm. CRO angle was constantly decreased during the observation period. Conclusions:The current findings suggest that the condyle grows in forward and upward direction.
4.Relationship of hypoxia-inducible factor-1 with the occurrence and development of tumor
International Journal of Surgery 2009;36(7):491-494
Hypoxia-inducible factor-I is the critical factor existed in mammal and human cells which plays an important role in maintaining the oxygen balance. Many hypoxia-responding genes can be activated by H1F-1. So, the relationship between HIF-land matrix matalloproteinases/stromal-derived factor-I/special CXC chemokin receptor/angiogenesis related factors is the hot spot in research of the tumor invasion and me-tastasis.
5.Progress of drug resistance mechanism in aggressive T cell non-Hodgkin lymphomas
Journal of International Oncology 2011;38(9):707-710
Aggressive T cell non-Hodgkin lymphomas are a group of highly malignant tumors characterized by rapid progress and short survival.This is especially true for patients who have a poor response to treatment because of their drug resistance.Hence,to clarify the mechanism of this resistance will have important guiding significance in reversing drug resistance and improving poor prognosis of aggressive T cell nonHodgkin's lymphomas.
6.Treatment of primary non-Hodgkin's lymphoma of the small intestine: an analysis of 33 cases
Chinese Journal of Radiation Oncology 1993;0(03):-
Objective To analyze the clinical feature, diagnosis, treatment a nd prognostic factors of primary lymphoma of the small bowel. Methods From Apr il 1989 to May 2002, 33 patients with non-Hodgkin's lymphoma of the small bowel were analyzed retrospectively. The Ann Arbor stages were: ⅠE 12, ⅡE 15 and Ⅳ E 6. The histological subtypes were: T-cell lymphoma 1 and B-cell lymphomas 32. A ll the patients received surgical treatment including radical or palliative rese ction. Twenty-six patients received postoperative radiotherapy including strip -f ield technique in 12 and opposed anterior-posterior fields in 14, with a median dose of 2543.5?cGy. Postoperative chemotherapy were applied to all patients inclu ding CHOP regimen in 17, COMP regimen in 6, COP regimen in 3, MINE regimen in 2, COPP regimen in 3 and BACOP regimen in 2. The median number of cycle was 4. Results The overall 5-year survival rate and disease-free survival rate were 48% and 39%. The 5-year survival rates were: ⅠE stage 42%, ⅡE stage 67% and ⅣE s tage 17%, respectively. Conclusions Most of the primary non-Hodgkin's lymphoma of the small intestine are in stage ⅠE and ⅡE, and the intermediate-grade and h igh-grade pathological subtypes are predominant. Surgery based combined treatme n t is effective and is advised. Radiotherapy and chemotherapy may improve the sur vival.
7.Effect of rosuvastatin on the expression of vascular cell adhesion molecule-1 of renal tissue in patients with the early-stage diabetic nephropathy
Chinese Journal of Postgraduates of Medicine 2011;34(28):10-13
Objective To observe the effect of rosuvastatin on the expression of vascular cell adhesion molecule-1 (VCAM-1) of renal tissue in patients with the early-stage diabetic nephropathy.Methods Sixty patients with early-stage diabetic nephropathy were divided into two groups by random digits table:rosuvastatin group and regular group.The patients were given 10 mg/d rosuvastatin besides the conventional treatment in rosuvastatin group.The levels of blood glucose,blood fat,renal function,high sensitivity C-reactive protein(hs-CRP),urine albumin excretion rate(UAER) and the expression of VCAM-1 were observed.Results Compared with those before treatment,the levels of total cholesterol (TC),low density lipoprotein cholesterol (LDL-C),trtglyeride (TG) showed no decrease after treatment [(5.83 ± 1.02),(3.48 ±0.60),(7.12 ±0.99) mmol/L] in regular group (P >0.05),but significantly decreased in rosuvastatin group [ (4.51 ± 0.95 ),( 3.18 ± 0.47),(7.02 ± 0.87 ) mmol/L ] (P < 0.01 ).The levels of UAER and hs-CRP were significantly decreased in regular group and rosuvastatin group after treatment [ (78.3 ±31.7),(53.8 ± 24.9) μ g/min,and (2.15 ± 0.48),( 1.59 ± 0.55) mg/L] (P< 0.01 ),then rosuvastatin groupwas more conspicuous than regular group (P < 0.05 ).The expression of VCAM-1 was less in rosuvastatin group than that in regular group.Conclusion Rosuvastatin can down-regulate the expression of VCAM-1 of kidney tissues in patients with the early-stage diabetic nephropathy and these indicate that rosuvastatin can reduce urine protein by inhibiting the inflammatory process.
8.Precision scientific literature novelty assessment promotes the development of clinical medicine in the era of precision medicine
Chinese Journal of Medical Library and Information Science 2016;25(12):70-72
Medical literature novelty assessment plays a unique role in the advances of medical sciences. The idea of precision medical literature novelty assessment was thus proposed according to the precision medicine program of army general hospitals, which has promoted the development of clinical medicine in our hospital by finding out the precision points of literature novelty followed by precisely retrieving.
9.Relationship between serum ferritin levels and cardiovascular risk in different genders of Chinese
Chinese Journal of General Practitioners 2017;16(1):39-44
Objective To evaluate the association between serum ferritin and the risk of cardiovascular disease among the Chinese population.Methods Based on the data from China Health and Nutrition Survey 2009, we used the Framingham risk score to calculate the 10-year risk of cardiovascular disease and analyzed the association between serum ferritin and the risk of cardiovascular disease in different gender by logistic regression analysis.Results Among 6 551 respondents, 3 035 (46.3%) were males and 3 516 ( 53.7%) were females whose mean age were ( 49.3 ±13.8 ) and ( 49.2 ±13.7 ) years, respectively.The median level of serum ferritin was 75.08 ( 36.71 -138.75 )μg/L.According to the 10-year risk of cardiovascular disease calculated by the Framingham risk score , the low risk group, middle risk group and high risk group were accounted for 79.5%( n=5 207 ) , 15.7% ( n=1 028 ) and 4.8%( n=316), respectively.The median of serum ferritin (121.61 vs.46.14, P<0.01) and the Framingham risk score (8.6 ±6.0 vs.7.3 ±1.6, P<0.01) of males were higher than those of females.The percentages of the middle risk group ( 30.6% vs.2.8%) and high risk group ( 9.8% vs.0.5%) of 10-year risk of cardiovascular disease in males were higher than those in females ( P <0.01 ).The 10-year risk of cardiovascular disease ≥10%increased with the increasing of serum ferritin in females ( trend P<0.01 ) but not in males.Conclusion Serum ferritin levels are positively correlated with the risk of cardiovascular disease in female Chinese.
10.Ethical Reflection on the Maintenance of Personal Dignity for Human Organ Donors
Chinese Medical Ethics 2017;30(3):363-366
It is of great significance to maintain personal dignity of human organ donors.There are three problems that may exist in the human organ donation.At the stage of registration,the potential donors may face family kidnapping;at the terminal stage,living with dignity for the donors is difficult to guarantee;at the post-donation stage,there is lack of humane care for the remains of donors and their close relatives.Aiming at the above problems,this paper made an analysis from the theoretical aspect and put forward three ethical principles:the principle of autonomy,respect and humanitarianism.
