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.

8. Application of dexmedetomidine combined with sufentanil in patient-controlled intravenous analgesia of puerperae with severe preeclampsia after cesarean section
Journal of Shanghai Jiaotong University(Medical Science) 2018;38(7):784-787
Objective • To investigate the effects of dexmedetomidine combined with sufentanil in patient-controlled intravenous analgesia (PCIA) of puerperae with severe preeclampsia after cesarean section. Methods • A total of 250 puerperae with severe preeclampsia who prepared to be treated by cesarean section were divided into observation group and control group by the random number table method with 125 cases in each group. They were given PCIA after operation. The PCIA formula for the observation group was dexmedetomidine combined sufentanil while that for the control group was sufentanil alone. The heart rate (HR) and mean arterial pressure (MAP) were compared between the two groups at different time points. Scores of visual analogue scale (VAS) and Ramsay sedation scale (RSS), the dosage of sufentanil and adverse drug reactions in both groups were recorded at 4, 8 and 24 hours after operation. Results • The HR and MAP of the observation group were significantly lower than those of the control group at 4, 8 and 24 hours after operation (all P<0.05). VAS scores in the observation group were significantly lower than those in the control group while RSS scores were significantly higher than those in the control group. The dosage of sufentanil was significantly less than that in the control group at 4, 8 and 24 hours after operation (all P<0.05). The incidence rates of nausea and vomiting in the observation group (12.80% and 7.20%) were significantly lower than those in the control group (32.00% and 16.00%) (all P<0.05). Conclusion • Compared with sufentanil alone, dexmedetomidine combined with sufentanil not only can significantly enhance the analgesic and sedative effects, but also can significantly reduce the dosage of sufentanil, and reduce adverse drug reactions in PCIA of puerperae with severe preeclampsia after cesarean section.

Chinese Journal of Digestive Surgery 2015;14(10):813-815
It is still a challenge for surgeons to deal with the complex abdominal wall defect.The purpose of surgical treatment is not only to restore the integrity of the abdominal wall, but also to maintain the function of the abdominal wall.Accurate classification and partition of the abdominal wall defects before operation are the base of surgical procedure for complex abdominal wall defects.Reinforcement of the abdominal wall defects with mesh, component separation technique and tissue flap technique are important methods to achieve functional repair of the abdominal wall defects.
10.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.
