OBJECTIVE To improve the professional ability of nosocomial infection managers.METHODS By analyzing the status quo and questions among nosocomial infection managers,we explored the essentiality of professionalism construction of the team of nosocomial infection managers and brought forward a way for it.RESULTS It is necessary to set up a professional education and culture system,improve the related guarantee system and keep the team of nosocomial infection managers in stabilization for strengthening the professionalism construction of the team.CONCLUSIONS It is the objective requirement to promote the construction and development of nosocomial infection discipline that impels professionalism construction of the team of nosocomial infection managers.

OBJECTIVE To investigate the function of department of nosocomial infection management in practice.METHODS It was analyzed the situation that the functional management of department of nosocomial infection in China could not be fully used at present.As far as the main content of nosocomial infection control was concerned,it brought forward the idea of performing the functional management of department of nosocomial infection in practice.RESULTS According to establishing the function of department of nosocomial infection management,strengthening the professional ability,and improving the service,both the effect and quality of nosocomial infection management could be enhanced.CONCLUSIONS The same as medical treatment,scientific research,nursing and logistic management,nosocomial infection management should stick to the legal management,and then its function can be effectively used.

Objective:To determine the effectiveness and validity of morphometric analysis made from dental panoramic tomograms(DPTs) for predicting mandibular bone mineral density(BMD) while taking the result of dual energy X-ray absorptiometry(DXA) as gold standard.Methods: Twenty healthy subjects(8 male,12 female) with intact dentition,aged from 1126 years old,were included in the present study.The BMD of each patient was measured at the lumbar spine(L1-L4) by DXA;the results were obtained based on the density of surface(g/cm2).Dental panoramic radiography was carried out using dental panoramic tomography(RTG230/ENR,made in Italy).Mandibular cortical thickness(MCT) and panoramic mandibular index(PMI) values were calculated and their relationship with DXA measurements were subjected to correlation analysis.The validity of MCT and PMI measurements were assessed by sensitivity and specificity.Results: We found mandibular BMD was positively correlated with MCT(r=0.268,P

OBJECTIVETo invesitigate the clinical effects of percutaneous closed reduction and cannulated screw internal fixation combined with external fixation in the treatment of unstable pelvic fractures.

METHODSFrom April 2006 to May 2009,29 patients with pelvic fractures of rotatory instability were treated with closed reduction and screw internal fixation combined with external fixation. There were 19 males and 10 females with an average age of 31 years old (ranged from 19 to 53 years). Based on the Tile classification,17 cases were type CI and 12 case were type C2. Tornetta standard and Majeed score were used to evaluated the clinical effect after operation.

RESULTSAll patients were followed up from 10 to 24 months with an average of 16 months. There were no nerve injuries and other organ injuries, only one case of infection was found and it was cured with wound dressing. Time of fracture union was from 14 to 18 weeks with the mean of 16.2 weeks. No loosening, slippage or breakage of the screw were found. According to the Tornetta standards,14 cases obtained excellent results, 10 good, 4 fair and 1 poor. The Majeed score was 87.2 ± 11.3, 16 cases got excellent results, 9 good and 4 fair.

CONCLUSIONClosed reduction and screw internal fixation combined with external fixation is an effective way to treat unstable pelvic fractures with Tile type C1 and Tile type C2.

Objective To explore the efficient way to purify and to enrich umbilical cord mesenchymal stem cells which have abilities to differentiate into chondrocytes. Methods Umbilical cord was acquired from new born infants and chopped into 1 mm2 cubics, then they were pretreated with colleganase and trypsin so as to get the mixed cell suspension. CD45(-),CD90(+) cells were acquired from the mixed cell suspension via FCM sorting and were cultured in the medium as umbilical cord mesenchymal stem PO cells. The PO cells were detached and passaged by multiplex collagenase NB4 and the positive rate of CD90 and CD45 of the P1-P3 cells were observeed via FCM ; the P3 cells were induced to differentiated into chondrocytes. Results FCM results showed that the positive rate of CD90 on P1, P2, F3 was (80.86 ± 7.85)%,(95.86± 3.28)%,(97.15± 1.43)%, while the positive rate of CD45 on P1, P2, P3 cells was (2.53 ±0.28)% and (0.97 ± 0.48)% and (0.05 ± 0.01)% respectively; P3 cells had differenciated into chondrocytes. Conclusion FCM presorting and Multiplex collagenase detachment procedures can swiftly acquire highly purified human umbilical cord mesenchymal stem cells which have the ability to differentiate into chondroeytes.

Objective To develop the clinical application and the method for functional repair in fa- cial nerve defect in parotideetomy of parotid carainoma.Methods Defect of facial nerve in parotidectomy was repaired by transplantation of sternocleidomastoid muscle-great auricular nerve flap with anastomosis of great auricular nerve-facial nerve under microscope.Results Eight eases of facial nerve defect in parotid carcinoma were repaired by this method.The facial nerve function almost recovered and access to normal dur- ing 3 to 6 month after operation in this series.6 of 8 patients achieved a gradeⅡ,2 of 8 patients achieved a gradeⅢ.Conclusion Reconstruction of facial nerve defect using sternocleidomastoid muscle-great auricu- lar nerve flap can provide better blood supply for the plerosis and regeneration of nerve.The nerve flap also ac- celerate the functional recovery after nerve grafting.

Objective To evaluate the results and toxic effects in three dimensional radiotherapy (3DCRT)with late course accelerated hyper-fractionation for advanced esophageal carcinoma.Methods From December 2001 to December 2003,115 patients were randomly divided into two groups:in 3DCRT group,55 patients were given late course accelerated hyper-fractionation radiotherapy to a total close of 66 Gy (2.0 Gy per fraction,5 times per week;to a dose of 36 Gy were changed into 1.5 Gy/f,2 f/d).In CF group,60 patients were given late course accelerated hyper-fractionation radiotherapy to a total dose of 66 Gy.Results The 1-, 2-,3-,4-year survival rates in 3DCRT group were 63.6 %, 50.9 %, 38.2 %, 30.9 % compared to 58.3 %, 38.3 %,33.3 %,23.3 % in CF group(X~2=4.44,P=0.031),and local control rates in 1-,2-,3-,and 4- years in 3DCRT group were 72.7 %,58.1%,47.2 % and 36.3 %,compared to 53.3 %,40 %,28.3 %,and 20 %(X~2=5.33,P=0.013)in CF group.However,in the 3DCRT group,the incidence of acute esophagitis was similar to CF group; hematogenous toxic and acute bronchitis were similar between the two groups. Late course lung injury in CF group was higher than that in 3DCRT group.Conclusion 3DCRT is able to improve the local control rate and survival rate,and unable to improve acute and late radiation toxie effects.
