Objective To investigate the predictive value of C-reactive protein(CRP)and serum calcium in the patients with acute pancreatitis(AP).Methods 85 cases of AP in our hospital from January to December 2013 were selected as the study subjects,in-cluding 40 cases of mild acute pancreatitis(MAP)and 45 cases of severe acute pancreatitis(SAP).40 cases of normal volunteers were selected as the control group.The levels of serum calcium and CRP were detected in the three groups by the automatic bio-chemical analyzer and turbidimetric immunoassay.Results The levels of serum calcium in the MAP and SAP groups was on the low side and significantly lower than that in the control group,but which in the MAP group were higher than that in the SAP group,the differences were statistically significant(P <0.05).The level of serum CRP in the MAP group and SAP group was high-er than that in the control group,and which in the SAP group was higher than that in the MAP group,the difference was statistical-ly significant(P <0.05).The level of serum calcium on the third after admission in the MAP and SAP groups was significantlyin-creased compared with the day of admission(P <0.05),but the levels of CRP in the MAP and SAP groups were significantly de-creased,the difference was statistically significant(P <0.05).The CRP detection was more in clinic,but the experiment indicating that simultaneous detection of serum CRP and calcium could significantly increase the accuracy,sensitivity and specificity of clinical judgement,the difference had statistical significance(P <0.05).Conclusion Serum calcium and CRP can be used as the predictive indexes for the condition progression and prognosis of acute pancreatitis and their joint examination can improve the sensitivity,spe-cificity and accuracy of the detection.

· AlM: To investigate clinical therapeutic effect and safety of small incision extracapsular cataract extraction combined with intraocular lens implantation in blindness prevention and treatment.
· METHODS: Clinical data of 425 patients with cataract (425 eyes) were analyzed retrospectively, who received small incision extracapsular cataract extraction combined with intraocular lens implantation in the No.413 Hospital of Chinese PLA, with the help from “handicapped rehabilitation engineering in Dinghai District of Zhoushan City” from September 2013 to August 2014.Visual acuity before and after operation, average corneal curvature, corneal astigmatism and intraoperative and postoperative complications were compared statistically and analyzed emphatically.
·RESULTS: ln all of the 425 patients with cataract (425 eyes) , the preoperative best corrected visual acuity of 99 patients were less than 0.05, and the other 326 patients were 0.05 to 0.3.Classification of lens nucleus hardness:level Ⅲ, 63 cases; level Ⅳ, 257 cases; and level Ⅴ, 105 cases.The preoperative average corneal curvature and corneal astigmatism of all patients were 44.6 ±1.52D and 1.35±0.96D.All the 425 patients underwent small incision extracapsular cataract extraction combined with intraocular lens implantation.Postoperative follow-up of 3mo results: the best corrected visual acuity: 5 cases were less than 0.05 (blindness-free rate 98.8%);8 cases were 0.05 to <0.3 ( handicap-overcome rate 96.9%);42 cases were between 0.3 to <0.5;127 cases between 0.5 to 0.8 and 243 cases were ≥0.8.Postoperative average corneal curvature and cornea astigmatism were 44.5 ± 1.42D and 1.47 ±1.00D respectively. There were no statistically significant difference compared with preoperative condition.No severe complications such as infectious endophthalmitis or retinal detachment occurred, except 4 patients ( 0.9%) with posterior capsular rupture and 3 patients (0.7%) with Descemet’s membrane detachment during operation;and 18 patients (4.2%) with transient corneal edema and 4 patients (0.9%) with hyphema after operation.
· CONCLUSlON: lt is effective and safe to apply small incisionextracapsular cataract extraction combined with intraocular lens implantation in blindness prevention and treatment, and it gives excellent visual rehabilitation to cataract patients.Especially in those areas and hospitals having no condition of phacoemulsification, it’s a safe and effective alternative when carrying out the program of blindness prevention and treatment.

Objective: To express glycosyl-phosphatidylinositol (GPI) modified Met- RANTES fusion protein on Chinese hamster ovary (CHO) cells and to develop a novel immunosuppressant GPI anchored form of Met-RANTES. Methods: The eukaryotic expression vector PEF/GPI-Met-RANTES were constructed and transfected into CHO cells by electroporation. The transfectants were selected with methotrexate (MTX). Expression of the recombinant protein was assessed by flow cytometric analysis, cell immunofluorescence staining and immunogold electron microscopy. Results: The chimeric molecules of GPI anchored form of Met-RANTES including the whole reading frame were constructed, and the sequence was identical to the designed sequence. GPI anchored form of Met-RANTES was stably expressed on CHO- DHFR- cells. Conclusion: A large amount of GPI modified Met-RANTES fusion protein was expressed on CHO cells. GPI anchored form of Met-RANTES may be used as novel immunosuppressant for suppressing reaction in graft rejection.

OBJECTIVEThis study aims to construct a three-dimensional finite element model of a maxillary anterior teeth retraction force system in light wire technique and to investigate the difference of hydrostatic pressure and initial displacement of upper anterior teeth under different torque values of tip back bend.

METHODSA geometric three-dimensional model of the maxillary bone, including all the upper teeth, was achieved via CT scan. To construct the force model system, lingual brackets and wire were constructed by using the Solidworks. Brackets software, and wire were assembled to the teeth. ANASYS was used to calculate the hydrostatic pressure and the initial displacement of maxillary anterior teeth under different tip-back bend moments of 15, 30, 45, 60, and 75 Nmm when the class II elastic force was 0.556 N.

RESULTSHydrostatic pressure was concentrated in the root apices and cervical margin of upper anterior teeth. Distal tipping and relative intrusive displacement were observed. The hydrostatic pressure and initial displacement of upper canine were greater than in the central and lateral incisors. This hydrostatic pressure and initial intrusive displacement increased with an increase in tip-back bend moment.

CONCLUSIONLingual retraction force system of maxillary anterior teeth in light wire technique can be applied safely and controllably. The type and quantity of teeth movement can be controlled by the alteration of tip-back bend moment.

Objective To study the effects of CBL teaching mode on treatment plan making process among orthodontic postgraduates. Methods Totally 42 junior and senior orthodontic post-graduates were randomly divided into 2 groups (21 per group)named as experimental group and test group. Each group was further divided in to 3 teams involved in CBL and traditional teaching. Six cases of the same type malocclusion were selected each time;after 4 teaching cycle,test scores of two groups were analyzed with SPSS 19.0. Results were shown as mean ± standard deviation and t test andχ2 test were applied to evaluate the rationality and accuracy of treatment plan made by students. Survey questionnaire were issued to teachers and students after class and the assessment results of CBL teaching mode were summed up. Results Test scores were (88.61±8.34)in experimental group and (76.13±8.59)in control group with significant differences (t=3.16,P=0.01). Pass rate of two groups were 96.12%and 87.51%with significant differences (χ2=4.76,P=0.02). During the first teaching program, accurate rates of experimental group and control group were respectively 31.00% and 36.70% and ra-tionality were 33.31%and 33.30%. During the second teaching program,accurate rates of experimen-tal group and control group were 68.80%and 45.70%and rationality were 62.72%and 43.37%. During the third teaching program,accurate rates of experimental group and control group were 89.70% and 51.20%,and rationality were 95.00% and 66.70%. During the fourth program,accurate rates of ex-perimental group and control group were respectively 97.80% and 55.30% and rationality were 98.30% and 75.60%. Conclusions CBL teaching mode is helpful to improve the students' ability of analyzing clinical cases and making more accurate and rational treatment plan,however the increasing teaching cost and the course load are also involved.
