Chitosan, deacetylated derivative of chitin, is a kind of natural polysaccharide polymer. It has advantages of rich source, good biocompatibility and biodegradation. Chitosan can be processed into porous scaffolds used for cell transplantation and tissue regeneration in bone tissue engineering, control-released carrier of growth factors and delivery vector of exogenous genes. Meanwhile, it can also be processed into injectable scaffolds used in bone tissue engineering in the form of microspheres or hydrogel. Chitosan and its derivatives will have broad application prospects in the research field of bone tissue engineering. However, chitosan composite scaffold has poor mechanical function, difficult accuracy control of In vivo degradation, and low efficiency for genetic carrier, chitosan research stays in in vitro tests and in vivo animal experiments. With the development of materials science and life science, chitosan will be widely used for clinical application of bone tissue defect.

Objective To screened out items with large proportion of technical analysis in obstetrics and gynecology physical examination by using statistical parameters Kappa index and to evaluate effect and clinical significance of Kappa index based on objective data and students' and teachers' subjective feeling.Methods We made Kappa index screening with double-blind method and established the Kappa index table for teachers and students.Students were randomly divided into conventional teaching group (n =26) and teaching reform group (n =29).Students in conventional teaching group traditionally followed the teacher to carry on the practice while those in teaching reform group received training according to the numerical value index and had examination after training.We paid attention to each student's weak points,provided personalized guidance and communicated with students actively.Results We found that it was uneasy for beginners to quickly grasp four step obstetrics palpation in-spection according to Kappa index.There were statistical differences in operation of gynecological physical examination between two groups (P =0.016).Conclusions Application of Kappa index can help us screen out skills in the operation suitable for training for eight-year program medical students.With quantitative evaluation,we can improve quality of clinical practice teaching in department of obstetrics and gynecology and guide educational reform.

Objective To discuss the effect and possibility of NIPPV in ILD combined with respiratory failure. Methods A total of 37 cases of ILD combined with respiratory failure admitted by our hospital during Feb 2004 to Oct 2007 were divided into treatment group (20 cases) and control group (17 cases). Routine pharmaceutical intervention was adopted in both groups while NIPPV was given in the patients of treatment group. The symptoms、signs and the arterial blood gases were observed and analyzed. Results Among 20 patients,3 gave up treatment , 17 patients were successfully treated with the NIPPV therapy. There were significant improvement of PaCO2、PaO2、pH and respiratory rate ,heart rate after 2h NIPPV. Conclusion NIPPV is an effective method for ILD combined with respiratory failure,which can save the patients life and decrease the complications.

Objective To investigate the effect of psychological stress on serum iron concentration of SD rats and its mechanism. Method SD rats were randomly divided into four groups: control group (CG), psychological stress 1w group (PG 1w) and 2w group (PG-2w), and psychological stress 2w with 1w free group (PG 2w-1w). The animal model of stress was tested for 1w, 2w, and 2w with 1w free from stress. The iron concentration of serum, liver, spleen and the expression of liver hepcidin were detected by atomic absorption spectrometry and Western blot respectively. Result (1) Compared with control group, serum iron concentration of rats under stress decreased. (2) Free of psychological stress 1w later, serum iron concentration was not significantly changed. (3) Iron concentration of liver and spleen was increased significantly compared with control group, and the expression of liver hepcidin was also increased. Conclusion Psychological stress may cause serum iron of rats to decrease obviously, and it was restored after 1w free from psychological stress. The mechanism is supposed to be increase of iron storage in liver and spleen by hepcidin in rats under psychological stress.

Objective To investigate clinical features and extent of gastric, liver and pancreatic damage of primary Sjgren syndrome(pSS). Method Clinical data of 152 pSS patients with gastric,liver and pancreatic damage were analyzed.Results The occurence of chronic atrophic gastritis(CAG),the most commonly seen gastic involvment in pSS,was 77.8%.The atrophic leisions differed with patient's age.Compared with the control group, the atrophy and intestinal metaplasia of the pSS patients with CAG were milder(P

Objective:To investigate the migration and odontogenesis of rat dental pulp cells transfected with adenovirus vector enco-ding cadherin-11.Methods:The dental pulp cells were cultured and transfected with pDC316-mCMV-EGFP-Cadherin-11.Cad-11 protein expression of the cells was examined by immunohistochemistry staining.The odontogenic differentiation of the cells was studied by alizarin red staining and ALP staining.The adhesion and migration of the cells were tested.Results:Transfection of pDC316-mC-MV-EGFP-Cadherin11 promoted Cad-11 protein expression and ALP activity,increased calcified nodule formation(P <0.05),adhe-sion and migration of rat dental pulp cells(P <0.05).Conclusion:Cadherin-11 may promote the odontoblast differentiation and mi-gration of rat dental pulp cells.

OBJECTIVETo summarize and analyze rules for acupoint selection and prescription composition in clinical literature regarding acupuncture for polycystic ovary syndrome (PCOS).

METHODSCHKD, VIP and Wan-fang databases were retrieved. The clinical literature data included in the study was collected. The descriptive statistical analysis was conducted on the main acupoints, main meridians of main acupoints, distribution of main acupoints, application of special points and rules for acupoint composition.

RESULTSFifty-two articles were included, involving 55 main acupoints with a total frequency of 375. The most frequent acupoints of acupuncture for PCOS were Sanyinjiao (SP 6), Guanyuan (CV 4), Zigong (EX-CA 1), Zhongji (CV 3) and Qihai (CV 6). The meridians of main acupoitns were conception vessel, spleen meridian of foot-taiyin and stomach meridian of foot-yangming. The main acupoints were distributed in the lower abdomen, lower limbs and back. In the special points, the use of front-mu points, five-shu points and back-shu points was more frequent. The prescription was usually consisted of 5 to 7 acupoints, (6. 9 ± 3. 6) acupoints in average.

CONCLUSIONIn the modern treatment of acupuncture for PCOS, Sanyinjiao (SP 6), Guanyuan (CV 4), Zigong (EX-CA 1), Zhongii (CV 3) and Qihai (CV 6) are most used. With the theories of meridian and zang-fu as essential references, the acupoint selection is based on disease differentiation and meridian circulation. Additionally, the methods for selecting the adjacent points and the distant points are adopted.
