Objective To explore the effectiveness of 125I seed implantation for gastric cancer and to determine whether the therapy could increase the survival rate.Methods Seventy-six gastric cancer patients in stage Ⅱ or Ⅲ were involved and randomly divided into treatment group (n =42) and control group (n =34)by simple random sampling method.The patients in the control group underwent D2 or D3 surgery and the patients in treatment group underwent D2 or D3 surgery plus interstitial implantation of 125I seeds.All patients signed the informed consents.Treatment results were evaluated as CR,PR,NC and PD.CR and PR were considered as effective and the effective rate was calculated.All patients were followed up and the three-or five-year survival rate was calculated,the complications were examined.x2 test was used to compare the significant difference between the two groups.Results The total effective rate in control group was 50.00% (17/34),lower than that of treatment group (73.81%,31/42; x2 =4.578,P<0.05).In the treatment group,the three-year and five-year survival rates were 61.90%(26/42) and 42.86%(18/42) respectively,and the corresponding rates in the control group were 11.76%(4/34) and 0(0/34) respectively (x2=19.771,19.094,both P<0.001).Both of the two groups had few severe side effects.Conclusion Radical surgery plus 1~Iseed implantation is effective and safe for the treatment of stage Ⅱ or Ⅲ gastric cancer and can further improvelong-term survival.

OBJECTIVETo evaluate a new treatment method for temporomandibular joint acute disk displacement without reduction.
METHODSTwenty-one patients diagnosed as acute anterior disk displacement without reduction were treated by manipulation with the aid of joint cavity extension followed by anterior repositioning splint. All and eleven of twenty-one patients were re-examined two weeks after insertion of splint and at the end of treatment (3 approximately 6 months later).
RESULTS(1) Degree of maximum mouth opening was increased from 25.8 mm before treatment to 46.6 mm 2 weeks after, 48.1 mm at the end of treatment; (2) Mean pain level (VAS) dropped from 2.62 before treatment to 0.43 2 weeks after, 0.18 at the end of treatment; (3) Fricton's TMJ dysfunction index and craniomandibular index decreased from 0.337 and 0.185 respectively before treatment to 0.021 and 0.011 respectively 2 weeks after, 0.031 and 0.018 respectively at the end of treatment.
CONCLUSIONSThe treatment method should be considered for acute anterior disk displacement without reduction if medication and physical therapy failed to have disk successfully reduced.

OBJECTIVE: To study the effects of occlusal trauma on the ultra-structure of synovial membrane and articular cartilage in rabbit's temporomandibular joints (TMJ). METHODS: TMJs from six rabbits with occlusal trauma and three control rabbits were studied by transmission electron microscopy. RESULTS: Degenerative changes in synovial membrane and articular cartilage of TMJ were induced following occlusal trauma. The structure of the articular surface was damaged, and chondrocytes in cartilage showed signs of degeneration. The synovial lining cells contained dense accumulations of vimentin intermediate filaments (IFs), which were especially prevalent in the cellular processes as well as paranuclearly. Microvilli on the synovial cell membrane were commonly seen. The "vermiform bodies" in the deeper interstitium of the synovial tissue were also found. Our findings of the punctate adherens between synovial lining cells were described in detail. CONCLUSIONS: The occlusal trauma is really a factor inducing degenerative changes of the TMJ.

OBJECTIVETo study the methodological techniques in measuring the severity of temporomandibulr disorders (TMD) and in evaluating the effectiveness of therapies in clinic.
METHODSBoth Fricton's Craniomandibular Index (CMI) and Helkimo's Clinical Dysfunction Index were calculated from 60 TMD patients. Inter-rater reliability was tested to assess the consistency in use between different examiners. Fricton's CMI was used to assess the clinical improvement after accepting a treatment in 21 TMD patients diagnosed as acute disk displacement without reduction.
RESULTSCorrelation Coefficient for inter-rater reliability in two groups was 0.879 and 0.939 respectively for Fricton's CMI and 0.744 and 0.838 for Helkimo Clinical Dysfunction Index. Fricton's TMJ dysfunction index was decreased from 0.337 to 0.021 (P < 0.001) and Fricton's CMI was decreased from 0.185 to 0.011 (P < 0.001) after the treatment in 21 TMD patients with disk displacement without reduction.
CONCLUSIONSTo avoid using subjective and descriptive report in assessment of the severity of TMD and the effectiveness of therapies, Fricton's CMI is recommended as an objective criteria which is simple in clinical use, and ease in scoring.

OBJECTIVETo study the distribution of the dominant perforators (the diameter > or = 0.8 mm) of the peroneal artery with color Doppler flow imaging (CDFI) for the purpose of anatomical preparations for the perforator sural neurocutaneous flap.
METHODSThe dominant perforators of the peroneal artery (DPPA) were studied with CDFI on bilateral legs of 20 healthy volunteers. The numbers, diameters and locations of the perforators were recorded for a statistical analysis. From Jan. 2005 to Jan. 2009, 51 free or pedicled sural neurocutaneous flaps supplied by a single DPPA were designed and harvested to repair the defects near the ankle (n=22), at the leg (n=15) and the forefoot or hand dorsum (n=14). The perforators were located preoperatively with CDFI and accuracy of CDFI was evaluated intraoperatively. The causes of false results were analysed to improve examining techniques.
RESULTSThe average number of DPPA was 4.2 with the average diameter of (1.13 +/- 0.24) mm (0.80-1.90 mm). They were located in the second to ninth segment of the line from the fibular caput to the tip of lateral malleolus which was equally divided into nine segments. The largest DPPA was (1.43 +/- 0.29) mm (1.00-1.90 mm) in diameter and most of them were located in the third to fifth segment (80.4%). The average diameter of the lowest DPPA was (1.02 +/- 0.16) mm( 0.80-1.30 mm) and they were located between the sixth to ninth segment. The total 169 DPPA as well as the largest ones mostly appeared in the middle third of the leg. All of the 51 flaps were transplanted successfully without necrosis, and no vascular problems occurred. Preoperative CDFI examination had a 93.6% true-positive rate and an 88.0% positive predictive value. What should be demonstrated was that if just considered the cases after Dec. 2007, the true-positive rate was 97%, and the positive predictive value was 93.9%.
CONCLUSIONSAccording to the distribution characteristics of DPPA, a sural neurocutaneous flap pedicled with one of this relatively large perforator can be designed and harvested to repair skin defects of leg and around ankle, but can not be utilized for that of forefoot. With anastomosis of the perforator, the flap based on the largest DPPA can be used as a free flap to cover defect anywhere. CDFI is reliable in preoperative location of DPPA, which makes the surgical procedures easier.
