BACKGROUND:Molars are characterized by multi-root, multi-root canal, multi-directional, different geometric shape and distribution. Single-root canal teeth post-core theory was used to guide molar repair in the clinic. It is easy to cause root canal perforation or vertical fracture due to excessive post preparation. Therefore, it is necessary to make further study and investigation in the design of fiber post-resin core for repairing molars. OBJECTIVE: To evaluate the clinical therapeutic effects of fiber post-resin core with different numbers of posts in the repair of molar residual roots and crowns. METHODS: A total of 54 human molar residual roots and crowns with sound root canal filing in 48 patients were selected and restored with fiber post of different numbers and resin core as wel as complete coronal restoration. There were 17 cases (20 samples) restored with single fiber post core, 16 cases (18 samples) restored with double fiber post cores, and 15 cases (16 samples) restored with three fiber post cores. They were folowed up for 24 months and the repair results were compared. RESULTS AND CONCLUSION:After 24 months of folow-up, the success rates were 85%, 94% and 94% in the single fiber post, double fiber post and three fiber post groups, respectively, and no significant difference was detected among the three groups. Five failures were observed among 54 teeth: three cases of fiber post shedding in the single fiber post group, one case of fiber post shedding in the double fiber post group, and one case of fiberpost shedding in the three fiber post group, and no root fracture occurred. Three kinds of fiber post-resin cores for repairing molar residual roots and crowns can get a better short-term clinical result. The repair effects were not different because of the different numbers of fiber posts.

Objective To compare the effect and safety of endoscopic duodenal papillal incision combined dilatation(ESBD) and endoscopic sphincterotomy(EST) in the treatment of common bile duct stone.Methods A retrospective analysis of 71 cases of choledocholithiasis,according to surgical methods,were divided into group EST (45 cases) and group ESBD (26 cases).The effect and safety of the above two kinds of treatment was evaluated through observing the rate of one-time stone clearance and postoperative complications.Results The success rate of removing calculous of the two groups was above 95%,and there was no significant difference between the two kinds of treatment(EST and ESBD)(P>0.05).Recent complications:the incidence rate of hemorrhage of the EST group was 0.0%,which of the ESBD group was 3.8%,there was no significant difference between the two groups(P>0.05).The incidence rate of postoperative pancreatitis of the EST group was 8.8%,which the ESBD group was 3.8%,there was no significant difference between the two groups(P>0.05).The diameter of the removed stone of the two groups:the EST group was (0.70±0.35)cm,and the ESBD group was (1.41±0.69)cm,there was significant difference between the two groups(P<0.05).Conclusion There are no significant differences in early complications and the success rate of removing stone between the EST group and the ESBD group.However,ESBD preserved teat sphincter's physiological barrier function to the greatest extent and the diameter of the removed stone was obviously larger than the EST group.Therefore,it is much safer for those who have quite large common bile duct stone or people who are with joint periampullary diverticulum to be treated by ESBD.

Lack of protection in education was one of possible reason contributed to the traditional Chinese medicine(TCM) psychology pathogenesis while the research conducted. This paper discusseds the following aspects: the concept, the causes, the impact and the types of protection. It also provided series thought on the development of TCM psychology pathogenesis, TCM psychology family treatment and family education of TCM psychology prevention.

For the research of TCM psychology pathogenesis, one possible reason could be concluded on the abnormal digestive process in psychology. This study discussed the concept of abnormal digestive process in psychology, including abnormal acception, digestion and metabolism in psychology. It provided foundation for the development of TCM psychology pathogenesis and TCM psychology clinical therapy.

During the research of TCM psychology pathogenesis, one possible reason may be theretardative solipsism thinking was one of TCM psychology pathogenesis in the study of TCM education therapy. This study discussed the concept of retardative solipsism thinking and its five types including personal preference type, selfishness type, arrogant type, autism type and escaping type.It provides foundation for TCM psychology clinical therapy.

OBJECTIVETo explore the impact of intracoronary bolus administration of tirofiban combined with nitroprusside through thrombus aspiration catheter or thrombus aspiration alone on myocardial reperfusion and major adverse cardiovascular events rate in acute anterior myocardial infarction patients with heavy thrombosis burden.

METHODSNinety consecutive acute anterior myocardial infarction patients with heavy thrombosis burden [(59.8 ± 11.5) years old] were randomly assigned to thrombus aspiration group (Group A, n = 30), thrombus aspiration and intracoronary tirofiban bolus (25 µg/kg prior to the first balloon inflation,Group B, n = 30), thrombus aspiration and intracoronary tirofiban combined with nitroprusside bolus (200 µg prior to the first balloon inflation, Group C, n = 30) with random number table. Baseline clinical data, angiographic features before and after percutaneous coronary intervention (PCI) and major adverse cardiovascular events after PCI between 3 groups were compared.

RESULTSThe baseline clinical data and angiographic features among 3 groups were similar (all P > 0.05) . The time of pain to balloon was (5.5 ± 3.8) hours. After primary PCI, myocardial tissue perfusion was significantly better in Group C than in Group A and Group B: TMP grade < 3 [10.0% (3/30) vs. 40.0% (12/30) and 33.3% (10/30), P < 0.01 and P < 0.05]. Left ventricular ejection fraction at 5 to 7 days after PCI also tended higher in Group C than in the other 2 groups (P = 0.05). One patient died of heart failure at 7th day after PCI in Group A, and no patient died in Group B and C. Thirty days after PCI, there was no re-myocardial infarction and target vessel revascularization event among 3 groups. The bleeding complication rate during 30 days follow-up was similar among 3 groups (P > 0.05) .

CONCLUSIONIntracoronary bolus application of tirofiban combined with nitroprusside through thrombus aspiration catheter after thrombus aspiration is associated with an improvement of myocardial reperfusion without increasing bleeding complication and other adverse cardiovascular events rate compared with thrombus aspiration alone in patients with acute anterior myocardial infarction and heavy thrombosis burden undergoing primary PCI.
