Objective:To design a system of computing and storing wound area. Methods:Visual C++6.0 platform has been used to develop the application.With image processing and by means of ADO, the wound area can be calculated and stored in the Access 2003 databse. Results:The system has achieved the expected effect which can be proved by measuring animal model and saving reaults. It can calculate the wound area and save the relative information fast. Conclusion:This system is qualified for computing and storing wound area and can search the information stored as well. Not only can it provide doctors with accurate information,but also bring patients convenience.

It has been demonstrated that connective tissue growth factor(CTGF) may enhance proliferation and differentiation of osteoblasts,inhibit the functions of osteoblasts,increase osteoclastogenesis in patients with Rheumatoid Arthritis,stimulate proliferation and differentiation of chondrocytes,and induce angiogenesis in vivo and vitro.Above all,CTGF plays an important role in sustaining growth of skeleton and cartilage,and thus maintaining bone quantity.

[Objective] To observe the effects of Oysters, Abalone shel , Concha arcae, Mother-of-pearl, Concha cypraeae, Clamshel , these six testacean TCM on the goiter rats. [Method] 72 healthy SD rats were randomly divided into nine groups:normal group, model group, positive group and six testacean TCM groups. Rats were given daily propylthiouracil (0.15 g·kg-1), continuous modeling for 10d, weighing thyroid wet weight,assaying T3, T4 and TSH contents in serum by ELISA, observing the morphological changes of thyroid under light microscope. [Result] Rats in the model group compared with normal group in-creased the relative weight of thyroid, reduced the content of T3,T4, and there was a significant difference( P<0.01), thyroid fol icular epithelial cellhyperplasia was obvious;compared with the model group, Oysters and Clamshel group made the content of T3,T4 in rat rebound, and there was a significant difference (P<0.05);Oyster and Clamshel group’s thyroid fol icular cellhyperplasia were not obvious, while the hyperplasia had different levels for the other 4 kinds of testacean TCM. [Conclusion] Oysters and Clamshel were better to improve the thyroid function of the goiter model rats.

Objective To discuss the levels of inhibitory protein Ga-2 (Gαi2) in hippocampus of brain and the effects of Gαi2 on neuronal intracellular Ca2+ level in cerebral ischemia reperfusion injury model of rats.Methods Ninety SD rats were randomly (random number) assigned to sham group (n =30),ischemic-reperfusion (IR) group (n =30),Pertussis toxin (PT) group (n =30).The blood flow of right common carotid artery of rat was blocked for 90 min to make ischemia reperfusion model.The levels of Gαi2 in hippocampus was assayed by immunohistochemistry and Western blotting after ischemia reperfusion for 6,12,24 h in each group.The average fluorescence values of intracellular Ca2+ levels in hippocampus of rats in three groups were detected by using Flow CytoMeter (FCM).Neuronal cell apoptosis was measured by TUNEL.Results After restoration of middle cerebral artery blood flow for different lengths of time,the levels of hippocampus Gαi2 and Ca2+ levels in IR group were significantly higher than those in Sham group (P ＜0.01).The hippocampus Ca2+ levels in PT group were higher than those in IR group (P ＜ 0.01).The apoptotic rates of neurons in PT group were lower than those in IR group (P ＜0.05).Conclusions The level of Gαi2 in cerebral ischemia reperfusion injury model was increased.Gαi2 might reduce the calcium ion concentration of neurons after cerebral ischemia and rcduce the neuronal cell apoptosis in this model.Gαi2 might play a role in protecting neuron from cerebral ischemia reperfusion injury.

Objective To analyze the reasons of the common complications happened after the operation of congenital syndactyly and to find the method of prophylaxis and treatment,and to improve the effects of treatment.Methods To classify the reasons of the complications happened after the operation of congenital syndactyly in 34 cases.Results The reasons of the complications included that the patients were not operated by special course of study doctors in 9; operation at an inappropriate opportunity in 8;the method of web taken shape was improper in 7;the method of nail taken shape was improper in 4; the fixation and training was unsuitable in 6. Conclusions The complications happened after the operation of congenital syndactyly will be reduced much , provided that grasping the right opportunity and selecting the proper method of web or finger tip taken shape before operation , taking care of the transformations of blood vessel and nerve in operation , fixing firmly and training appropriately after operation.

Sepsis has poor prognosis, and its pathogenesis is not clear. Chemokine CX3CL1 (Fractalkine, FNK) has many functions such as chemotaxis, adhesion and mediate immune injury. CX3CR1 is the only receptor of CX3CL1 and participates in the development of sepsis. Here we review the structure, biological function and possible mechanism of CX3CL1 and CX3CR1 in the pathogenesis of sepsis.

Objective:To evaluate effects of traction arch combined with protraction on dental and skeletal changes in patients with Angel Ⅲ malocclusion in mixed dentition.Methods:Seventeen patients with Angle Ⅲ malocclusion were selected and treated with traction arch combined with protraction. Cephalometric radiographs were taken 6 months before the initiation of treatment, at the initiation of treatment and 6 months after treatment.Cephalometric analysis was used to examine the dental and skeletal changes.Results:Significant changes of maxillary anterior displacement and mandibular downward and backward rotation were observed in the seventeen patients:SNA increased 2.6?,A point moved forward 3.1 mm. The overjet correction of anterior teeth was 5.2 mm, 63% of the overjet correction was due to skeletal changes and 37% due to dental changes. Conclusion:Traction arch combined with protraction is a simple and effective apparatus in the treatment of Angle Ⅲ malocclusion.

Objective To analyze drug resistance data of Enterococcus faecalis and Enterococcus faecium,submitted by member units of Chongqing bacterial drug resistance monitoring network,and to provide the basis for our city effective application of antimicrobial agents and the reference.Methods Target bacteria identification and drug susceptibility test were performed by member units,according to the national technology scheme of bacterial drug resistance monitoring network and the results were determined according to standards published by Clinic and Laboratory Standard Institute(CLSI) in 2015.WHONET5.6 software was used to analyze drug susceptibility,and drug resistance difference was analyzed by using SPSS21.0 software.Results A total of un-repeated 1 811 strains of Enterococcus faecalis and 1 601 strains of Enterococcus faecium,accounting for 13.1% of all positive strains.The resistant rates of the two kinds of bacteria to vancomycin were 0.5% and 1.8%,to rinathiazole amine were 2.5% and 0.5% respectively.Tigecycline resistant strains were not founded.The resistant rate of Enterococcus feaclis to ouinupristin/dalfopristin was 90.1%,to tetracycline was 78.8%,to high concentration of gentamicin was 43.0%,to penicillin,ampicillin and nitrofurantoin was less than 7%.Except ouinupristin/dalfopristin and tetracycline,the resistant rate of Enterococcus faecium to the other drugs were significantly higher than Enterococcus faecalis(P<0.05).Strains isolated from children and adult patients,Intensive Care Unit(ICU) and un-ICU patients were with differences of drug resistance(P<0.05).Conclusion Most of Enterococcus infection could be caused by Enterococcus faecalis and Enterococcus faecium.Monitoring of drug resistance might be helpful for rational and effective usage of antimicrobial agents.
