Following with the naissance and the development of the DICOM(the Digital Image Communication in Medicine) protocol,and numerous medical image equipments factory's support to the DICOM protocol,PACS(picture archiving and communication systems)are popularized quickly in hospital image section room,which pushes the progress of PACS industry.Hospitals have always been certain blindness in ushering and arguing PACS systems,uncertain how to control those providing company exactly on the technique.In this paper,some key problems are introduced in order to make everyone understand the relevant technique.

Cancer pain can seriously disturb patients′quality of life.Intractable cancer pain not ame-nable to standard analgesics is a horrifying truth in parts of the patients.Interventional pain management tech-niques can be an effective alternative for those patients.Based on the evidence of evidence-based medicine, celiac plexus block or splanchnic nerve block are recommended for the management of upper abdominal cancer pain,pelvic cancer pain can be managed with superior hypogastric plexus block,and back pain due to vertebral compression fractures with tumor invasion can be managed with percutaneous vertebroplasty or kyphoplasty. Intercostal nerve block for chest wall cancer pain,ganglion impar block and saddle block for perineal pain due to pelvic tumors should be used only in the context of an experimental study or in cases of compassionate use with no other available forms of effective pain relief.

Objective To investigate the feasibility and technique of laparoscopic subtotal cholecystectomy(LSC).Methods Totally 168 patients were converted to LSC because of failure in laparoscopic cholecystectomy(LC).During the LSC,the Calot's triangle was separated and then the Hartmann's pouch was incised to decreased the intracystic pressure for the removal of the stones.Results Among the cases,5 patients were converted to open surgery for subtotal resection of the gallbladder.LSC was completed after clipping the cystic duct and artery in 122 patients;in the other 41 cases,the gallbladder was cut at the Hartmann's pouch to clip the bile duct and artery or suture the neck of the gallbladder,and then LSC was performed.The median operation time was(65.5?15.2)min,and the intraoperative blood loss was(71.5?15.5)ml.The time to resume the diet was(20.4?6.3)h postoperation.After the operation,7 patients developed local complications(4.2%),and the mean postoperative hospital stay was(4.2?2.6)d.Of the patients,105 were followed up for(25.5?6.5)months,during this period,5 patients had dyspepsia,3 had right shoulder pain,and 9 had right hypochondrium pain.Conclusions LSC is feasible for patients with complicated cholecystitis.It is important to control the perioperative hemorrhage and bile leakage.

Objective To compare the two cell adhesion assay techniques based on 51 Cr release and 3H-TdR incorporation.Methods Firstly,the cells to be tested were cultured to confluence in the 96 well plate for 24 hours. After with 51 Cr or 3H-TdR label, the isotope labeled cells were add into plate wells and incubated for another 4 hours. Then the un-adhered cells were removed by gently washing. The cpm of two assay system were counted, the sensitivity and stability of two methods were compared.Results Assay methods based on 51 Cr release and 3H-TdR incorporation could both reflect the cell adhesion level correctly. In assaying sensitivity and stability showed that the 3H-TdR incorporation assay was better than in 51 Cr release assay.Conclusions Adhesion method based on isotope label could provide good sensitivity and stability. The sensitivity and stability of 3H-TdR incorporation is better than that of 51 Cr release assay.

Objective To investigate whether curcumin could inhibit the metastasis of pancreatic cancer in vitro and in vivo and its mechanism.Methods Pancreatic cancer AsPC-1 cells were treated with different concentrations of curcumin.After 72 hours,cell survival rate were detected by MTT and the appropriate concentration of curcumin was selected.After treated with 6 μmol/L curcumin,early apoptosis of AsPC-1 cells were detected by Annexin V-FITC/PI double staining flow cytometry,and the effects of curcumin on the migration and invasion of AsPC-1 cells were observed.After establishment of the orthotopic nude mouse model of pancreatic cancer,the mice were orally treated with low dose (20 mg/kg body weight) and high dose (40 mg/kg body weight) of curcumin respectively.Eight weeks later mice were sacrificed to observe the tumor metastasis,immunohistochemical methods were used to detect the positive expressions of CD34,NF-κB and MMP-9 in the tumor tissue.Results Curcumin of different concentrations could inhibit the proliferation of AsPC-1 cells and induce its apoptosis in a dose dependent manner,and 6.μmol/L was the best dose of curcumin.After 6 μmol/L curcumin treatment,the migration coverage of AsPC-1 decreased from 70％ to 10％,the number of penetrating cells decreased from 136/200x magnification to 17/200x magnification,and the difference between the two groups was statistically significant (P ＜0.05).In the nude mouse model of pancreatic cancer,the size of the tumor decreased from (97.8 ± 15.3) mm3 to (44.3 ± 9.7) mm3 in high dose group and (28.1 ±7.1)mm3 in low dose group,the number of distant metastasis decreased from 108.3 ±6.7 to 29.5 ±4.5 and 8.9 ± 2.4,the expression of CD34 decreased from 20.5 ± 2.3 to 10.3 ± 1.2 and 7.9 ± 3.2,and the expression of MMP-9 decreased from 85.2 ± 2.3 to 53.2 ± 1.2 and 34.2 ± 3.1,and the difference was statistically significant (P ＜ 0.05).Conclusions Curcumin can inhibit the metastasis of pancreatic cancer both in vitro and in vivo,and its effect may be related to the inhibition of expressions of CD34 and MMP-9.

Objective To observe the effects of two rehabilitation programs to staff in office with cervical spondylosis,and to explore the appropriate rehabilitation program for this group of people.Methods There were 37 office personnel with cervical spondylosis were selected by the inclusion criteria.They were randomly divided into treatment group A(once a week,n=17) and treatment group B (once a week,n=20) according to the random number table method.The treatment group A took middle frequency electrotherapy and infrared therapy,while the treatment group B took tuina manipulation.The changes of visual analogue scale (VAS) and cervical range of movement (ROM) were observed after 10 weeks of treatment.Results Compared with before treatment,the VAS scores of the two treatment groups decreased with statistically significant difference after 10 weeks of treatment(tA=12.91,tB=13.88,all P<0.05).There was no significant difference in VAS score between the two treatment groups after treatment(t=0.22,P>0.05).Compared with before treatment,the cervical ROM of the two groups increased significantly after treatment(tA anteflexion=-4.59,tA posterior extension=-5.13,tA left flexion=-4.24,tA right flexion=-3.25,tA left circumflexion=-7.13,tA right circumflexion=-7.47,tB anteflexion=-5.85,tB posterior extension=-7.28,tB left flexion=-8.64,tB right flexion=-8.38,tB left circumflexion=-11.72,tB right circumflexion=-11.95,all P<0.05).There were significant differences in the increase range of flexion,left flexion and left circumflexion between the two treatment groups after treatment(tflexion=-2.29,tleft flexion=-2.77,tleft circumflexion=-2.32,all P<0.05),but posterior extension,right flexion and right circumflexion had no statistically significant diffferences(tposterior extension=-1.97,tright flexion=-1.97,tright circumflexion=-1.97,all P>0.05).Conclusion The two kinds of rehabilitation programs can relieve the neck pain of the office personnel,but treatment group B is better than treatment group A in increasing cervical ROM.
