OBJECTIVETo explore clinical efficacy of double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I in treating acromioclavicular dislocation with Rockwood type III - V .

METHODSFrom January 2010 to September 2013, 56 patients with Rockwood type III - V acromioclavicular dislocation were treated by operation, including 20 males and 36 femlaes, aged from 32 to 52 years old with an average of 38.5 years old. Twenty-five patients were on the left side and 31 cases on the right side. The time from injury to operation was from 3 to 14 days, averaged 7 days. All patients were diagnosed as acromioclavicular dislocation with Rockwood type III - V, and double Endobutto were used to reconstituting coracoclavicular ligament, line metal anchors were applied for repairing acromioclavicular ligament. Postoperative complications were observed, Karlsson and Constant-Murley evaluation standard were used to evaluate clinical effects.

RESULTSAll patients were followed up from 8 to 24 months with average of 11 months. According to Karlsson evaluation standard at 6 months after operation,42 cases were grade A, 13 were grade B and 1 was grade C. Constant-Murley score were improved from (42.80±5.43) before operation to (91.75±4.27) at 6 months after operation. All items at 6 months after operation were better than that of preoperative items. Forty-eight patients got excellent results, 7 were moderate and only 1 with bad result. No shoulder joint adhesion, screw loosening or breakage were occurred during following up.

CONCLUSIONDouble Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I for the treatment of acromioclavicular dislocation with Rockwood type III - V could obtain early staisfied clinical effects, and benefit for early recovery of shoulder joint function.

Objective To investigate the homology of methicillin-resistant Stphylococcusaureus(MRSA)from the neonatal intensive care unit(NICU)of a children's hospital,and evaluate routes and preventive strategies of MRSA healthcare-associated infection(HAI). Methods MRSA strains from neonates and environment of NICU between October and December 2014 were collected,and strains were identified by VITEK-2 microbial analysis system and cefoxitin Kirby-Bauer method,homology of MRSA was analyzed by pulsed-field gel electrophoresis (PFGE ). Results A total of 6 MRSA strains were isolated from NICU between October and December 2014,3 of which (bed-58,70,and 100)were detected MRSA from specimens,MRSA were isolated from neonatal incubator and nurse (nasal swabs and hands)who cared for neonate at bed 58. 5 of 6 MRSA strains were homology,antimicrobial susceptibility testing result showed that No. 1-5 strains were resistant to clindamycin and amoxicillin/clavulanic acid,No. 6 strain was slightly different from No. 1-5 strains,No. 6 strain was susceptible to both clindamycin and amoxicillin/clavulanic acid. PFGE results showed that No. 1-5 strains were of the same type,No. 6 strain was a different type. Conclusion The main route of this MRSA transmission is contact transmission,especially through the hands of health care workers,identification and analysis of epidemic strains by PFGE technique is an effective measures to prevent HAI outbreak and perform epidemiological study.

Objective To explore the establishment method of virtual three-dimensional model of the virtual artery and interven-tional devices,and its application value.Methods The virtual models including virtual artery system,catheter,guide wire,stent and coil were established by using the three-dimensional moulding software of 3D Studio MAX R3.The study about interventional preoperative simulation and assistant instruction were run in personal computer.Results ①All the virtual instruments and real in-struments were highly similar shape,the arterial system in the visual display was similar to realistic system.②All arteries branches had own name,could be arbitrarily adjusted curvature,diameter and established the lesion morphology.③The reference value of preoperative simulation results to guide the actual surgery included following aspects:to guide the reasonable shaping of micro-cathe-ter and micro-guide wire tip,to plan the coil and stent deployment location,number and size.④In training and teaching,the preop-erative simulation could assist doctors in learning and remembering the artery branch and establishing the concept of three-dimen-sional space,and enhanceing the intention understanding of surgery.Conclusion The establishment method of virtual model of the virtual artery and interventional devices is reliable.The preoperative simulation results can be used to guide practical operation with relatively high accuracy,and it has an important supporting role for the teaching and training of medical students.

An analysis method has been established to test 27 elements (Li, Be, B, Mg, Al, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Sr, Mo, Cd, Sn, Sb, Ba, La, Hg, Pb, Bi) in Maca nationality's medicine with microwave digestion-ICP-MS. Sample solutions were analyzed by ICP-MS after microwave digestion, and the contents of elements were calculated according to their calibration curves, and internal standard method was adopted to reduce matrix effect and other interference effects. The experimental results showed that the linear relations of all the elements were very good; the correlation coefficient (r) was 0.9994-1.0000 (Hg was 0.9982) ; the limits of detection were 0.003-2.662 microg x L(-1); the relative standard deviations for all elements of reproducibility were lower than 5% (except the individual elements); the recovery rate were 78.5%-123.7% with RSD lower than 5% ( except the individual elements). The analytical results of standard material showed acceptable agreement with the certified values. This method was applicable to determinate the contents of multi-elements in Maca which had a high sensitivity, good specificity and good repeatability, and provide basis for the quality control of Maca.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

Presently, there are many issues in traditional Chinese medicine (TCM) decoction, such as the uncertain sources of TCM, the lack of reminder for medication taboo, the nonstardard herb operation, and difficult supervision, etc. A digital service system of TCM decoction was established to solve the problems mentioned above. The digital service system mainly includes automatic coding for checking in & out, drug medication taboo database, digital operation in decoction, distribution through 2D code, the corresponding application for mobile phone, and the information supervision platform for TCM decoction. The digital service system of TCM decoction can track the quality & duty of the pieces, remind decoction medicine contraindications, improve the standard operation process of decoction, develop decoction distribution & tracking through cell phone, save the waiting time, and hence provides a new supervising method for TCM decoction. The digital service system of TCM decoction solves the key issues for the formula, operation, delivery and supervision of TCM. In the same vein, this system will expand the market share of TCM decoction and promote the development of TCM.
