Objective To histomorphometricly assess changes occurred in the alveolar ridge following different methods of socket preservation and to compare them against natural healing without interventions. Methods The second、 third and fourth mandibular premolars were extracted from six beagles. Six extraction sites in each dog were randomly assigned to three treatments as follows:natural healing (T1), Bio-Oss Collagen (T2) and immediate implant with Bio-Oss (T3). Six month after surgery, the dogs were euthanized and tissue samples were sectioned, fixed and mounted, then were stained with toluidine blue. The histologic studies and morphological measurements were performed by using an optical microscope and a digital image software. Results Reabsorption in the buccal aspect of the alveolar crest of ridge was showed in all groups. With respect to the mean vertical bone loss of the buccal bone plate, T3 is lower than T1 and T2(P<0.001 ), while no significant differences were observed between T1 and T2. With regard to horizontal dimension of the alveolar process , a statistical significance could be found at 3mm and 4mm below the crest of ridge in group T1 and T3(P=0.017, P=0.042), while no statistical differences were found between other groups. Conclusions Both techniques of alveolar ridge preservation were not able to completely preserve the original bone volume after tooth extraction. Immediate implant placement in combination with Bio-Oss seems to have the potential to limit the reabsorption of the alveolar process efficiently , but the bone preserving effect of Bio-Oss Collagen is undesirable.

Objective:To study the change rule of rats'pulse waves after kidney resection.Methods:To collect the pulse waves of femoral artery in each side of rats in Drugged state.Then do one-side kidney resection operation,after fully recover from it,collect the pulse waves again.To average the pulse waves in the same cycle length and then do the LSQ regression by 6 harmonics which are correspond with the cycle lengths,analyze the phase and the amplitude of vibration of fundamental wave and harmonics by statistical method.Results:The amplitude of vibration of the 3rd harmonics of pulse waves of femoral artery in the same side with operation and the amplitude of vibration of the 1st to 5th harmonics of pulse waves of femoral artery in the other side with operation has reinforced, the phase of the 1st and 2nd harmonics also have changed regularly.Conclusion:There're some regular changes in the pulse waves of rats after one-side kidney resection operation,which shows that the pulse waves of artery on the body surface can reflect the splanchnic changes.This research can offer some scientific foundation to the pulse-diagnosis in TCM.

Objective To investigate the clinical and mammographic features of plasma cell mastitis.Methods Twenty-five patients(28 lesions)with histologically confirmed plasma cell mastitis, aged from 26 to 70 years(mean age 41 years),were examined with X-ray mammography.The clinical manifestations and imaging features were retrospectively reviewed.Results No case was in lactation.The painful irregular masses,ranged from 1.3 to 8cm in size,were found in 22 patients,while 3 patients with acute episode.Recurrent episodes of breast masses were noted in 4 patients.Based on the mammographic appearances,the plasma cell mastitis were classified as the following four types:inflammation-like type (2/28),ductal ectasia type(3/28),focal infiltration type(10/28)and nodular type(13/28).The valuable radiogyaphic signs:(1)An asymmetrically increased density along the lactiferous duct with a flame-like appearance,inhomogeneous low density tubular structures and scattered stick-shape calcifications.(2) Architectural distortion and oil cysts formation in adjacent area,(3)Subareolar ductal ectasia.Conclusions The clinical and mammographic characteristics of plasma cell mastitis are critical to avoiding unnecessary surgery.Histopathological result is needed for the diagnosis in patients highly suspected of malignancy.

As the main part of the teaching activities,students play an important role in the teaching reform.The students were trained through 3 pathways,“Extending teaching activities from the classroom to the outside”,“Development from basic to clinical knoledge” and “Culturing students' innovative consciousness”,so as to allow them to give full play in teaching reform,to enhance their ability of practice and learning by themselves,to culture their innovative consciousness and to develop students' leading functions in the anatomy teaching reform.

?AlM:To compare the anti-inflammatory effects with lotrprednol-tobramycin and tobramysin-dexamethasone eyedrops after phacoemulsification combined intraocular lens implantation.
? METHODS: ln this prospective, comparative, randomized controlled trial, patients with senile cataract who underwent phacoemulsification combined intraocular lens implantation in our hospital from January 2014 to October 2014 were enrolled, which were randomly divided into two groups. Patients were given lotrprednol -tobramycin ( LE/T group ) and dexamethasone-tobramysin ( D/T group ) eyedrops respectively. Preoperative and postoperative intraocular pressure, malnutrition inflammation score, bruggrmann comfort scale were observed.
?RESULTS:A total of 143 eyes of 143 cases were enrolled, of them 81 cases were in the LE/T group and 62 in the D/T group. There were no statistically significant differences between the two groups in malnutrition inflammation score and bruggrmann comfort scale. The average intraocular pressure was 16. 5±3. 1mmHg in D/T group after 14d postoperation, which was obviously higher than LE/T group ( 14. 7± 3. 7mmHg, P = 0. 004 ). After 14d postoperation, the intraocular pressure of 2 cases were > 21mmHg, which were back to normal after drug withdrawal.
? CONCLUSlON: The anti - inflammatory effects lotrprednol-tobramycin and tobramysin-dexamethasone eyedrops are similar after phacoemulsification. However, lotrprednol-tobramycin has little influence in intraocular pressure, and more safety.

OBJECTIVE To investigate the antimicrobial-resistant genes and consanguinity in multi-resistant Pseudomonas aeruginosa(MRPA) isolated from the 98th Hospital of PLA,Huzhou,Zhejiang Province,China.METHODS Thirty strains of MRPA were isolated from hospitalized patients between Sep 2003 and Oct 2004.Twenty four kinds of genes of blaTEM,blaSHV,blaOXA-10 group,blaPER,blaVEB,blaIMP,blaVIM,blaGES,blaCARB,blaDHA,blaMIR,aac(3)-Ⅰ,aac(3)-Ⅱ,aac(3)-Ⅲ,aac(3)-Ⅳ,aac(6′)-Ⅰ,aac(6′)-Ⅱ,ant(3″)-Ⅰ,ant(2″)-Ⅰ,aph(3′)-Ⅵ,oprD,qacE△1-sul1,catB,and cml1 were analyzed by PCR and verified by DNA sequencing.Resistant-genes cluster analysis was performed by Average.RESULTS In 30 strains of MRPA the positive rate of genes of blaTEM,blaOXA-10 group,blaCARB,aac(3)-Ⅱ,aac(6′)-Ⅰ,aac(6′)-Ⅱ,ant(3″)-Ⅰ,ant(2″)-Ⅰ,qacE△1-sul1,and cml1 were 66.7%,3.3%,3.3%,76.7%,3.3%,33.3%,53.3%,26.7%,83.3%,and 3.3%,respectively,and the deficiency rate of oprD gene was 90.0%.The gene of blaOXA-10 group was sequenced and determined to be blaOXA-10 subtype ESBL gene.But the rest of genes were all negative.According to the cluster analysis of resistant-gene,30 strains of MRPA isolated could be classified into four subgroups,which were caused by the infection in hospital.CONCLUSIONS At least 10 kinds of antimicrobial-resistant genes exist in MRPA isolates,and the deficiency rate of oprD gene is very high.MRPA can induce clone transmitted hospital infection and it has fulminant prevalence.

OBJECTIVE To investigate the ?-lactamase genes in 4 kinds of nonfermenting Gram-negative bacilli isolated from the 98th Hospital of PLA. METHODS Sixty strains of Acinetobacter baumannii,30 strains of Pseudomonas aeruginosa,19 strains of Stenotrophomonas maltophilia,and 15 strains of Flavobacterium were isolated from hospitalized patients.Nine kinds of ?-lactamases genes of TEM,SHV,OXA,CTX-M,PER,VEB,IMP,VIM and GES were analyzed by PCR and verified by DNA sequencing. RESULTS In A.baumannii and(P.aeruginosa),the positive rates of gene of TEM were 100.0% and 66.7%,respectively.SHV gene was positive in 18 of 60 strains of A.baumannii tested,17 of which were SHV-12 subtype ESBLs.The other was a new SHV type ?-lactamase nominated SHV-48.OXA gene was positive in 1 of 30 strains of P.aeruginosa tested,it was an OXA-10 subtype ESBLs.But the rest of genes were all negative. CONCLUSIONS There exist 4 kinds of(?-lactamase) genes at least in nonfermenting Gram-negative bacilli including TEM-1,SHV-12,SHV-48,and(OXA-10.)
