OBJECTIVE:To study the effects of different extraction methods on the content of cholalic acid from Artificial Bezoar. METHODS: Artificial Bezoar from 3 different habitats was used to extract cholalic acid by hydrolization vs. hydrolization-free method, and the content of cholalic acid was determined by HPLC-ELSD(high performance liquid chromatography with evaporative light scattering detection). RESULTS: The content of cholalic acid in the hydrolyzed sample was higher than that in the non-hydrolyzed sample of the same batch. CONCLUSION: Through hydrolization, the binding cholalic acid in the artificial bezoar was transformed into free cholalic acid so that the content of cholalic acid was increased. Therefore, it is more reasonable to control the quality of Artificial Bezoar by taking the contents of total cholalic acid and free cholalic acid as indexes.

Objective; To investigate the immunolocalization and significance of Notch-2 expression in the process of dental pulp repair after injury. Methods: An experimental animal model of injury-induced pulpitis was established to observe the time-sequenced alteration of the expression of Notch-2. Results: Three days post-operation, weak positive staining of Notch-2 was observed in pulp mesenchyme cells and pulp fibroblasts but not in vascular endothelial cells or odontoblasts. Five days post-operation, strong Notch-2 reactivity was found in subodontoblasts as well as newly bom capillary endothelial cells. Seven days after cavity preparation, Notch-2 staining became weaker in pulp mesenchyme cells and capillary endothelial cells, but stronger positive staining was found in odontoblasts. Two weeks post-operation, weak Notch-2 staining was seen in pulp mesenchyme cells and subodontoblastic layer cells and was absent from odontoblasts. Notch-2 immunoreactivity was completely absent in intact rat dental pulp. Conclusion: Notch-2 is strikingly up-regulated in dental pulp mesenchyme cells in the early days after dental injury and then shows progressively up-regulation in odontoblasts. Properly regulated activation of Notch signaling pathway is important for controlling cell fate and maintaining the correct balance among cell proliferation, differentiation and apoptosis during dental pulp repair process.

Depression and insomnia are intimately related. Depressed patients usually manifest sleep discontinuity and early awakening, reduced or no slow wave sleep (SWS) and shortened latency of rapid eye movement (REM) sleep. These sleep abnormalities are very similar to those caused by over activated hypothalamic-pituitary-adrenal (HPA) axis with stress. Therefore, the animal models developed by post-traumatic stress disorder or chronic unpredictable mild stress could be used to evaluate drugs which have effects of both anti-depression and improvement of sleep quality, and to provide a more reliable platform for further studis on the mechanisms of depression and accompanied insomnia. This review mainly focuses on the typical features of sleep disturbance of depression, possible pathophysiological mechanisms, establishment of animal stress models and analysis of their abnormal sleep characteristics.

Objective To establish the culture technology system for the in-vitro induction of adventitious buds of Sarcandra glabra(Thumb.) Nakai by investigating the induction factors of in-vitro adventitious buds.Methods Stem segments of Sarcandra glabra were cultured as explants.The effects of culture medium with different concentrations of 6-benzylaminopurine(6-BA) and indole butyric acid(IBA) added,lighting time,light intensity,and temperature on the induction of adventitious buds from the explants were observed.Results The medium containing both 6-BA and IBA was more effective to induce shoot formation of Sarcandra glabra than the medium only containing 6-BA or IBA;high concentration of plant hormones would block the growth of the plantlets.The scattering light or faint direct light was suitable for the shoot formation,while dark or strong light would induce the plantlets withered or even dead.Temperature in the range of 25 ℃～30 ℃ was beneficial for the growth of adventitious buds,and the bud induction rate arrived 100% at the temperature of 25 ℃.Conclusion At the temperature of 25 ℃,the faint sunlight or direct light less than 2000 lux,and the medium with 2.5 mg?L-1 6-BA and 0.1 mg?L-1 IBA added can stimulate significantly the adventitious bud formation of Sarcandra glabra,the induction rate up to 82.98%.

OBJECTIVETo clarify the related factors of marginal bone loss (MBL) around tissue level implants in the posterior part of the mandible.

METHODSA total of 116 tissue level implants were implanted in the mandibular posterior region of 76 patients. Patients' information, including general characteristics, implant characteristics, implant site characteristics, and prosthesis characteristics, was recorded. Their cone beam computed tomography data were measured immediately after implant placement, 3 months later, and 3 and 12 months after prosthesis loading. The measurement of MBL was conducted by One Volume Viewer software. SPSS 20.0 was used for statistic analysis.

RESULTSSmoking, cortical bone thickness (CBT), collum angle (CA), and implant local sanitation showed significant differences with body mass loss (P<0.05). No significant differences were found among sex, age, length of implant, diameter of implants, implant systems, bone height, prosthesis type, and MBL (P>0.05).

CONCLUSIONThe risk factors that caused MBL were smoking, thicker CBT, larger CA, and poor implant local sanitation. Among them, poor implant local sanitation had the highest correlation with MBL.

Objective To explore the risk factors of hyperbilirubinemia in late preterm infants. Methods Clinical data of 211 cases of late preterm infants with hyperbilirubinemia and 246 cases of late preterm infants without hyperbilirubinemia were retro-spectively analyzed between 2011 and 2012. The risk factors of hyperbilirubinemia were filtered. Results Twenty-seven cases of late premature infants with hyperbilirubinemia were severe. Hospital stay less than 3 days, birth asphyxia history, small for gestatio-nal age, head hematoma, delivery injury, hypoalbuminemia, polycythemia, infection, hemolytic disease, feeding intolerance, and fe-tal excretion delay were associated with hyperbilirubinemia (P<0.05). Rural origin, pregnancy-induced hypertension syndrome and premature rupture of membrane were also associated with hyperbilirubinemia (P<0.05). Multivariate logistic regression analysis showed the history of birth asphyxia , fetal excretion delay, hypoalbuminemia, pregnancy-induced hypertension syndrome were risk factors of hyperbilirubinemia in late preterm infants (OR=2.35-4.05). Pregnancy-induced hypertension syndrome and hemolytic dis-ease were risk factors of severe hyperbilirubinemia in late preterm infants (OR=5.74, 73.64). Conclusions Neonatal asphyxia, fetal excretion delay, hypoalbuminemia and pregnancy-induced hypertension syndrome are risk factors of hyperbilirubinemia in late pre-term infants. Strengthening the management of pregnancy-induced hypertension syndrome and the treatment of newborn hemolytic disease can reduce the occurrence of severe hyperbilirubinemia in late preterm infants.
