OBJECTIVETo study the patterns and morphologic characteristics of blunt head injury and analyse its formative mechanism in attempt to provide references for medicolegal expertise.
METHODSThe statistical analysis was done in terms of gender, age, as well as the nature, pattern, location, and feature of the injuries.
RESULTSAmong the 202 cases of head injury-induced death, 124 were male and 78 female with the age ranging from 1-81 years. Death caused by homicide was dominant (106, 52.5%), followed by suicide (49, 24.3%) and accident (44, 21.8%). The majority of suicide-induced death were by falling from height, and traffic crash was responsible for majority of unexpected death cases. The morphology and pathogenesis of the injuries varied according to differences on the mode, magnitude, and orientation of the outside force giving rise to blunt injury as well as the character of vulnerants.
CONCLUSIONStudies on the morphology and its formative rationale of blunt head injury will offer easy access to medicolegal expertise on the mode and character of the injury.

OBJECTIVEThis prospective study was to observe the correlation between the mesial papilla's height of single implant-supported maxillary central incisor and the distance from the base of the contact point to the alveolar bone crest.
METHODS56 patients involved in single implant-supported maxillary central incisor were included in this study. The distances from the base of the contact point to the alveolar bone crest in the digital periapical film of maxillary central incisor were measured using the software Planmeca Dimaxis Version 3.3.2. The time of measurements were as follows: The pre-surgical and post-surgical periods, before and after the crown installation, the follow-up examination of more than 0.5 year. To analyze the factor of influencing distance, and the correlation between the distance and the height of gingival papilla during the whole restored period. Correlation analysis between the distance and the height of gingival papilla during the whole restoration was done by the statistical software SPSS 12.0.
RESULTSThe results demonstrated that the ratio of esthetic papilla can achieve 54.5% at the crown installation and 95.5% at the follow-up examination when the distance was between 3 mm and 5 mm. When the distance was between 5 mm and 6 mm, they dropped to 30.0% and 75.0%, respectively. However, when the distance increased to above 7 mm, the papilla could hardly be in an esthetic outcome. There was a significant change of the distance was found during the periods from the post-surgery to pre-restoration, and the scope of the changes was between -0.13 mm and 0.46 mm. A negative correlation was found between the distance and the index of papilla. The correlation coefficient r was -0.715 (P < 0.01).
CONCLUSIONIt is proposed that the pre-surgery distance of maxillary central incisor from the base of the contact point to the alveolar bone crest can be used as one of the important reference indexes to assess and predict the height conditions of gingival papilla.

OBJECTIVEBy studying the mode and morphologic character of high fall injuries on the scene, and exploring the injury situation of different heights, different fall ways and postures, to provide a reference for the forensic identification of high fall injury.
METHODSAll the high fall cases were statistically analysed according to their gender, age, ground-touching posture, fall height, site and type of the injury.
RESULTSAmong 134 high fall cases, 98 were male and 36 were female with the age ranging from 2-71 years (37.6+/-16.9 on average), in which, 10-60 years old group consisted of 110 cases (82%). Most cases fell from windows or roofs (73%) and the touching objects were cement ground or shaft bottom of elevators. Among these cases, head injury was generally serious, followed by chest and abdominal injuries. The morphologic changes depend upon the height, nature, as well as the posture at the point while the body touches the ground.
CONCLUSIONMorphologic study of high fall injury assists medicolegal physicians to make correct identifications of the cause and nature of high fall injuries.

OBJECTIVETo report our primary experience with immediate breast reconstruction using laparoscopically harvested omental flap after breast-conserving surgery. The safety, feasibility, and clinical effect are also evaluated.
METHODSFrom Jun. 2010 to Jan. 2011, 5 cases who underwent immediate breast reconstruction using laparoscopically harvested omental flap after breast-conserving surgery were retrospectively analyzed. The operative duration, postoperative days in hospital, complication and therapeutic effect were reviewed.
RESULTSAll the patients were treated successfully without laparotomy. The average operative duration was 310 min, including 60 min for harvesting the omental flap. The median postoperative days in hospital was 8 days (ranged, 5-9 days). One case complained of slight pulled feeling in upper abdomen. No other complication happened. The cosmetic result of reconstructed breasts was satisfactory.
CONCLUSIONSThe immediate breast reconstruction using laparoscopically harvested omental flap is safe and feasible with less morbidity in donor sites and good cosmetic effect. It is one of the ideal methods for immediate breast reconstruction.

OBJECTIVETo evaluate the efficacy and safety of aildenafil citrate, an oral phosphodiesterase type 5 inhibitor, in the treatment of erectile dysfunction.
METHODSIntegrated analyses were made of 8-week, randomized, double-blind, placebo-controlled phase 2 clinical trials involving 250 men with mild-to-severe erectile dysfunction of various etiologies who received aildenafil citrate 30 or 60 mg (n = 167) or placebo (n = 83).
RESULTSThe statistic results of International Index of Erectile Function, Patient Sexual Encounter Profile (SEP) diaries and Global Assessment Question (GAQ) were significantly higher in the aildenafil citrate patients than in the placebo controls. The main drug-related adverse events were flushing, headache, dizziness and naupathia, which were mild and could be self-relieved.
CONCLUSIONThe aildenafil citrate therapy significantly ameliorated erectile function and was well tolerated by a wide range of patients with erectile dysfunction.

Saponin frsom Cortex Albiziae (SCA) are extensively used in the clinical treatment of tumor and depression. However, SCA may cause several adverse effects, including reproductive toxicity. The present study was designed to assess the mechanism by which SCA cause reproductive toxicity in female mice. The general reproductive toxicity testing was accomplished in female Kunming mice. The animals were divided into four groups: three groups that were treated by oral gavage with 135, 270, and 540 mg·kg(-1)·d(-1) of SCA prepared in physiological saline, respectively, and one vehicle control group that was treated with physiological saline only. The gestational toxicity tests were conducted at 540 mg·kg(-1)·d(-1). The general reproductive toxicity results showed that the pregnancy rate of the SCA-treated group decreased with the pregnancy rate being decreased by 70% at 540 mg·kg(-1)·d(-1). SCA elicited maternal toxicity in the ovary and the uterus, but no fetal toxicity or teratogenicity was observed. The rates of implantation in the early, middle, and late pregnancy were all decreased, with stillbirths and maternal deaths being observed. Histopathological changes showed that SCA adversely affected the ovary and the uterus. In conclusion, SCA-induced reproductive toxicity in female mice is most likely caused by its damage to the ovary and the uterus.
