Objective To determine the safety location of the bony tunnel in reconstruction of the coracoclavicular ligaments on the basis of digital characterization of the anatomy of the clavicle and coracoid process.Methods Unilateral shoulder spiral CT scan was conducted in 30 patients without injury to the clavicle or coracoid process.They were 15 men and 15 women,aged from 20 to 71 years old (average,49.3 years).Thirty 3D digital models of the clavicle and coracoid process were constructed using the CT scan data by Mimics13.0.Half of the models were of the left shoulder and half of the right.Anatomic measurements of the clavicle and coracoid process were carried out on these models.Virtual transclavicular-transcoracoid bony tunnels were established according to the anatomy of the conoid ligament.Parameters of these bony tunnels were measured before the safety location was calculated.Results The mean clavicular length was 147.70 ± 5.34 mm in males and 133.09 ± 6.61 mm in females; the distance between the lateral edge of the clavicle and the center of the conoid tuberosity (CCD) was 35.90 ± 3.16 mm in males and 30.48 ± 0.54 mm in females; the distance between the lateral edge of the clavicle and the center of the trapezoid tuberosity (CTD) was 22.68 ± 1.23 mm in males and 18.69 ± 1.65 mm in females,with significant differences between genders (P ＜ 0.05).There were no significant differences between male and female regarding the ratio of the CCD to the clavicular length,the ratio of CTD to the clavicular length,or the mean internal rotational angle of the coracoid process (P ＞ 0.05).According the attachments of the conoid ligament on the clavicle and coracoid,from the superior-posterior edge of the clavicle to the anterior midpoint of the coracoid basement,the bony tunnels were established.These tunnels nearly bisected the cross section of the clavicle and coracoid basement,35.23° ± 2.36° medially inclined to the sagittal section and 5.91° ± 2.14° posteriorly inclined to the coronal section of the body.Conclusions To ensure that the bony tunnel should pass through the center of the clavicle and coracoid,it should be drilled from the superior-posterior edge of the clavicle and located at the clavicular attachment of the conoid ligament,tilting about 35° medially and 6° posteriorly to aim at the anterior midpoint of the coracoid basement.

Objective To investigate the influence of nursing intervention on perioperative psychological status and treatment compliance of patients undergoing breast augmentation. Methods 82 patients were investigated with self-rating anxiety scale (SAS), self-rating depression scale (SDS), self-designed mental activity questionnaire on patients with breast augmentation. And they were divided into the intervention group(42 patients) and the control group(40 patients) randomly. The control group was given routine treatment and nursing. The intervention group received systematic nursing intervention such as psychological needs,confidentiality, the relevant specialist knowledge and explanation and prevention o complications besides routine treatment and nursing care. The perioperative psychological status and treatment efficacy were compared between the two groups. Results The worrying degree about operation - related problems was lower in the intervention group compared with that of the control group, but SAS and SDS score showed no significant difference one day before operation between the two groups. SAS and SDS score of the intervention group were improved before discharge compared with those before operation and were also better than those of the control group. Conclusions Patients undergoing breast augmentation surgery subject to a variety of perioperative psychological barriers, systematic nursing intervention can significantly improve the psychological state and treatment compliance, make them to acquire the unification of perfect body shape and psychology with best physical and mental status during perioperative stage.

OBJECTIVE:To improve the process efficiency of automatic dispensation machine before dispensing. METHODS:After building quality control circle(QCC)in the hospital inpatient,according to the steps of QCC,the key links and factors that affect process efficiency of automatic dispensation machine before dispensing were found out,corresponding countermeasures were developed based on causes,then it was evaluated by process time and other indexes in dispensing before and after the development of QCC. RESULTS:The 2 links(removing the drug packaging,manually counting and developing add-drug list)with the longest time before dispensing improved work efficiency by setting add-drug quantity and variety truly,timing checking dispensation medi-cine,timely counting dispensation medicine drug list,strengthening training and other methods,process time of automatic dispensa-tion machine before dispensing was shortened from 179.8 min(before)to 119.2 min(after)(shortened by 33.7%),target achieve-ment rate was 168.5%;and QCC staff showed positive growth in means, responsibility, team cohesion, and other aspects (increase rate were 15%-81%). CONCLUSIONS:QCC shows obvious effect on improving process efficiency of automatic dispen-sation machine before dispensing.

RESULTS: The function of the DCR has gradually extended from quality control of self-made drugs to the monitoring on hospital drug quality and solving of the problems encountered in clinical practice. CONCLUSIONS: The function of the DCR should be enhanced further to shift its focus from drug-centered to patient-centered so as to enhance hospital medical service level and promote rational drug use.

Baculovirus has many advantages as vectors for gene transfer. We demonstrated that recombinant baculovirus vectors expressing p35 (Ac-CMV-p35) and eGFP (Ac-CMV-GFP) could be transduced into human kidney 293 cells efficiently. The level of transgene expression was viral dose dependent and high-level expression of the target gene could be achieved under the heterogonous promoter. MTT assay suggested that both Ac-CMV-p35 and Ac-CMV-GFP did not have cytotoxic effect on human embryo kidney 293 cells. Cell growth curve showed the Ac-CMV-p35 and Ac- CMV-GFP transduced and non-transduced cells had similar proliferation rate, so baculovirus-mediated p35expression had no adverse effect on cell proliferation. In addition, baculovirus-mediated p35 gene expression protected human embryo kidney 293 cells against apoptosis induced by various apoptosis inducers such as Actinomycin D, UV or serum-free media. These results suggested that the baculovirus vector mediated p35 gene expression was functional and it could be widely used in molecular research and even gene therapy.

BACKGROUND:Coracoclavicular ligament reconstruction with transclavicular-transcoracoid driling is an effective surgical technique to treat acromioclavicular dislocation. A good driling in the clavicle leads to a perfect bony tunnel and a good surgery. OBJECTIVE: To observe the effects of different driling positions of the clavicle on the location of bony tunnels in coracoclavicular ligament reconstruction. METHODS:Sixty three-dimensional digital models of the clavicle and coracoid process were constructed by Mimics13.0. Virtual transclavicular-transcoracoid bony tunnels were established according to different surgical planes with different driling positions in the clavicle. Parameters of these bony tunnels were measured, and the safety was evaluated. Option 1: The driling was made 30 mm distal to the clavicle, located in the center of the front and rear edges of the clavicle surface. Option 2: The driling was made 40 mm distal to the clavicle, located in the center of the front and rear edges of the clavicle surface. Option 3: The driling was made at the straight line of tapered nodule tip and the midpoint of the base of the coracoid process, located at the rear edge of the clavicle upper surface. RESULTS AND CONCLUSION: Bony tunnels in option 1 were extremely on the inside of the coracoid. Bony tunnels in options 1 and 2 were not in the center of clavicle. Bony tunnels in option 3 were in the center of both clavicle and coracoid. The method of locating the driling position with a certain distance to the distal clavicle leads to different results in man’s and woman’s models. To ensure that the bony tunnel can pass through the center of clavicle and coracoid, it is suggested to dril at the straight line of tapered nodule tip and the midpoint of the base of the coracoid process and nearby the rear edge of the clavicle upper surface.
