ObjectiveTo compare therapeutic effects of the bone-guided tissue regeneration in combination with a composite bovine-derived xenograft versus flap surgery only on intra-bony defects in elderly patients with periodontal disease. MethodsThirty elderly patients with periodontal disease were randomly divided into two groups. One group was treated by the bone-guided tissue regeneration in combination with a composite bovine-derived xenograft (experimental group). The other group was treated by flap surgery only (control group). Probing depth (PD)and clinical attachment level (AL) were determined before surgery and six months after treatment in two groups. The change of bone amount was also determined before surgery and six months after treatment through computer-assisted densitometric image analysis(CADIA). ResultsThe changes of PD and CADIA were (3.8+1.7)mm, (20. 3+11.1)g/mm2 in experimental group and were (2.5+1.1)mm, (9.4+8. 6)g/mm2 in control group. The differences between two groups were significant (P.＜0. 05). The change of AL was (3.5+ 1.6)mm in experimental group, compared with control group(2. 3 1.7)mm, which showed more obvious regeneration of alveolar bone (P＜ 0. 01). ConclusionsGuided tissue regeneration in combination with a composite bovine-derived xenograft appears to be more effective than flap surgery only for intra-bony defects in elderly patients with periodontal disease.

Robotic system helps surgeons in performing surgery. Currently Da Vinci system is the most popular. Da Vinci system has been used for the stomach and bowel diseases in 27 cases(18 cases of stomach and 9 cases of colon and rectum) in the Zhongshan Hospital, Fudan University. Accurate preoperative staging is crucial, and Da Vinci system is advantageous in lymph node dissection, preservation of nerve plexus, and complete resection of mesorectum. Adoption of gastrointestinal tract reconstruction technique should depend on the operation and experience in surgery. Though Da Vinci system has limitations and the cost is high, it is believed to be the future trend.

Objective To investigate clinical characteristics of moderate and severe ovarian hyperstimulation syndrome (OHSS) in assisted reproductive technique .Methods The clinical data of 179 cases with moderate and severe OHSS receiving in vitro fertili‐zation‐embryo transfer (including ICSI) in the hospital from June 2012 to April 2013 were analyzed retrospectively .According to the clinical characteristic ,the OHSS was classified as as the moderate type and severe type ,and the late type and early type . Results It was no statistics difference between moderate type and severe type in the patients age ,number of retrieved oocytes ,ad‐mission transaminase ,proportion of fibrinogen normal numbers(P> 0 .05) .But it was a statistics difference between moderate type and severe type in the occurring time days of hospitalization ,hematocrit on admission ,albumin value ,transaminase maximum ,albu‐min dosage used ,proportion of paracentesis number ,pregnancy rate(P < 0 .05) .It was no statistics difference between early type and late type in the patients age ,admission transaminase ,proportion of fibrinogen normal numbers(P> 0 .05) .But it was a statistics difference between early type and late type in the number of retrieved oocytes ,the proportion of moderate OHSS patients ,days of hospitalization ,hematocrit on admission ,albumin value ,transaminase maximum ,albumin dosage used ,proportion of paracentesis number ,pregnancy rate(P< 0 .05) .Conclusion Synthesizing OHSS patients′ blood indexes ,we can evaluated patients′ pathogenet‐ic condition ,the treatment of disease ,and took appropriate preventive measures as soon as possible .Patients with late type may be have more severe pathogenetic condition than patients with early type .

By analyzing scientific research misconduct and its causes,this paper revealed the conflicts between interests of researchers and management,and proposed measures and suggestions to construct scientific integrity system in Chinese institutions by drawing on experiences from Australia、UK and America.
