tep immunochromatographic method accounted for 96.4%.Conclusion Both RT-PCR and step immuno chromatographic method can not be used as means of short-term therapeutic effect evaluation.

Objective:To study clinical efficacy of one-visit versus two-visit root canal therapy for pulpitis, apical periodontitis and taintless teeth with nickel-titanium rotary instruments and ultrasonic irrigation unit. Methods: A total of 309 patients with 338 teeth were selected. The teeth were classified into pulpitis group, apical periodontitis group and taintless teeth group. Patients were randomly assigned to either the one-visit or two-visit root canal therapy, the treatment effects were evaluated with clinical trial and radiography after 3 days, 1 week, 1 month and 3 months. Results: The short-term outcome was changes in apical bone density by using the periapical index (PAI), long-term outcome exhibited equally improvement in clinical curative effect in both groups. Although one-visit root treatment could cause more intensive postoperative pain than that of two-visit endodontic treatment during 1-3 days, the indisposition could be eliminated by using medicine. Conclusion: By using of the nickel-titanium rotary instruments and canal ultrasonic irrigation unit, the cure rate of root canal therapy of one-visit and two-visit endodontic treatment has been improved, with no significant difference between two groups, so that one-visit root treatment can be used in clinic.

Objective To observe the therapeutic efficacy of acupuncture plus moxibustion in treating chemoradiotherapy-induced leukopenia in patients with malignant tumors.Method A total of 120 patients with malignant tumors who presentedleukopenia during receiving chemoradiotherapy were randomized into two groups. Sixty cases in the treatment group were intervened by acupuncture plus moxibustion; sixty cases in the control group were intervened by oral administration of Batilol tablets and Leucogen tablets.The peripheral white blood cell (WBC) count in the two groups was detected on treatment day 3, 7, 14, 21, and 28.The clinical efficacies of the two groups were compared.ResultThe WBC started toincreaseafter 1-week treatment in thetreatment group (P<0.05) and the increase was statistically significant after 2-week treatment (P<0.01); in the control group, the WBC started to increase after 2-week treatment (P<0.05)and the increase was statistically significant after 3-week treatment (P<0.01); the effect of increasing WBC was more significant in the treatment group compared to the control group (P<0.05,P<0.01).The total effective rate was 90.0% in the treatment group versus 53.3% in the control group, and the between-group difference was statistically significant (P<0.01).Conclusion Acupuncture plus moxibustion can produce a significant efficacy in treating leukopenia induced by chemoradiotherapy.

Prostasomes are one of the subcellular structures secreted by prostatic epithelial cells.They present in human semen as membranous vesicles with average diameter of 150nm(40-500nm).440 proteins have been identified in human prostasomes and possess many physical functions.Prostasomes may not only exert a motility function for spermatozoa by delaying the acrosome reaction,but also have immune regulatory function,antibacterial and antioxidant characteristics.Prostasomes can be isolated from the serum and urine,and they present both in normal and prostatic cancer tissues.Prostasome can be a special prostatic biomarker and has a close association with prostatitis and prostate cancer.

Objective To observe the efficacy and prognosis of aconite-cake-partitioned moxibustion plus acupuncture in treating peptic ulcer.Method Thirty-four patients in the treatment group were intervened by aconite-cake-partitioned moxibustion plus acupuncture, while thirty-three patients in the control group were by Omeprazole Enteric-coated Capsules. The clinical efficacy, the effect on ulcer under gastroscope and Hp, and the therapeutic efficacy 12 months after the intervention were evaluated.Result The total effective rate was 91.2% in the treatment group versus 72.7% in the control group, and the difference was statistically significant (P<0.05). For ulcer by gastroscopy, the total effective rate was 85.3% in the treatment group versus 69.7% in the control group, and the difference was statistically significant (P<0.05). After intervention, the Hp level didn’t show significant change (P>0.05). The relapse rate of the control group was higher than that of the treatment group 12 months after the intervention.Conclusion Aconite-cake-partitioned moxibustion plus acupuncture can produce a higher efficacy than Western medication in treating peptic ulcer.

Objective To observe the clinical efficacy of acupuncture-moxibustion in treating endometriosis (EM). Method Fifty EM patients were randomized into two groups, 25 cases in each group. The treatment group was intervened by acupuncture-moxibustion, while the control group was intervened by oral administration of Mifepristone tablets. Abdominal pain, pelvic lump, and relevant indicators were observed before and after the treatment, and the therapeutic efficacies were compared.Result After 6-month treatment, symptoms including abdominal pain obviously subsided in the treatment group and the total effective rate was 92.0%, versus 52.0% in the control group, and the between-group difference was statistically significant (P<0.01). The pelvic lump size was significantly changed after the treatment in both groups (P<0.05), suggesting that the lump size became smaller in both groups after the treatment;there was a significant difference in comparing the pelvic lump size between the two groups after the treatment (P<0.05), indicating that the lump size was reduced more significantly in the acupuncture-moxibustion group. The level of serum CA125 changed significantly after the treatment in both groups (P<0.05), suggesting that serum CA125 dropped in both groups after the treatment; there was a significant difference in comparing the level of serum CA125 between the two groups after the treatment (P<0.05), indicating that serum CA125 dropped more significantly in the acupuncture-moxibustion group. A year later, there was a significant difference in comparing the relapse rate between the two groups (P<0.05), revealing that the relapse rate was significantly lower in the acupuncture-moxibustion group than in the medication group.Conclusion Acupuncture-moxibustion can produce a marked therapeutic efficacy in treating EM.

ObjectiveTo evaluate the marginal integrity of restoration in two types of mate- rials, or resin- modified glass ionomer cement and polyacid- modified composite resin (compomer). MethodsRestorations of four kinds of material (GC Fuji Ⅱ LC, VitremerTM, Dyract compomer and F2000 compomer) were placed in the facial Class V cavity preparations in forty noncarious human molar teeth. The teeth were randomly assigned to 4 experimental groups of 10 teeth each. After thermal cy- cling( × 20,5 ～55℃ ), the teeth were immersed in 1％ basic fuchsin dye for 24 hours at room tempera- ture. Staining along the teeth restoration interface was recorded. ResultsThe data indicated signifi- cant differences between all the restorative materials for both occlusal and gingival scores ( P=0.026, P = 0. 000)respectively. Further analysis revealed there were statistically significant differences between GC Fuji Ⅱ LC and others on occlusal margins versus Dyract compomer and others on gingival margins. Conclusion Factors such as dental conditioning, rates of water absorption and thermal coefficient were related to microleakage. Resin - modified glass ionomer cement showed less microleakage than polyacid- modified composite resin tested.

BACKGROUND:Tissue patch is used to increase bone mass after mandibular molar extraction, which is conducive to late-stage repair, but it is unexpectedly found that after implantation of tissue patch, incidence of dry socket is significantly reduced.OBJECTIVE:To assess the efficacy of tissue patch for the control of dry socket caused by mandibular molar extractionvia the method of systematic review. METHODS:MEDLINE (OVID), CENTRAL, EMBASE and CBM were searched for clinical randomized controled trials and clinical controled trials. The keywords were “dry socket, tissue patch, acelular dermis matrix, tooth extraction” in English and Chinese. The references of the included studies and 19 Chinese dental journals were hand-searched. Two reviewers independently assessed the risk of bias using Cochrane Colaboration’s tool, and extracted data. Meta-analysis was delivered with Revman 5.1.RESULTS AND CONCLUSION:Eight studies, including five randomized controled trials and three clinical controled trials, were included. Totaly 2 052 participants were involved. Seven of the included studies had moderate risk of bias and one had high risk of bias. Meta analysis showed that implantation of the tissue patch into the extraction socket could reduce 86% of the risk of dry socket (relative risk=0.14, 95% confidence interval [0.08, 0.26], P < 0.000 01). Sensitivity analysis showed that this outcome was relatively stable. Implantation of tissue patch into extraction socket could significantly reduce the risk of dry socket, but more randomized controled trials are needed.

Objective To explore the management alternatives to tr aumatic periprosthetic femoral fractures after hip replacement. Metho ds A retrospective analysis was done on five cases of traumatic perip rosthetic femoral fractures posterior to hip replacement admitted in from June 1 998 to June 2003. There were two males and three females, with age range of 52- 71 years (average 59 years). One case suffered from traffic accident and the oth er four from slipping. Three cases had received hip replacement for femoral head aseptic necrosis, the other two for femoral neck non-union. Total hip replacem ent was carried out in four cases (five hips) and femoral head replacement in on e. These traumatic periprosthetic fractures occurred from one month to 17 years after hip replacement. According to classification to periprosthetic fracture of Vancouver (1995), there were 3 cases of type B and 2 type C. Two cases (one cas e of type B and one type C) were treated with traction and conservative treatmen ts, two (type B) with long shaft prosthesis revision combined with shape memory saw tooth embracing fixator or wires and one (type C) with anatomical plate inte rnal fixation. Results All 5 cases were followed up for f rom two months to five years and attained fracture union with no complications s uch as infection, nonunion or fixation breakage. Conclusions Traumatic periprosthetic femoral fractures after hip replacement are hard to deal with. The management alternatives differ according to fracture site, prost hesis loosening, bone quality and general status of patients. Classification cri teria and corresponding managements of periprosthetic fractures of Vancouver are proved to be suitable guidelines.

砄bjective: To investigate the effect of calcitonin gene related peptide(CGRP) on calcification function of human dental pulp cells(HDPCs) in vitro . Methods: HDPCs cells were exposed to calcitonin gene related peptide at the dosages(mol/L) of 10 -12 , 10 -10 and 10 -8 for 3,6,9, 12 and 15 days respectively. Cell growth was studied by cell counting , alkaline phosphatase(AL) by a AL kit, osteocalin by immunoradiological tecnique and type I collagen mRNA expression by RT PCR. Results: CGRP did not show any effect on the growth of HDPCs, but it increased the expression of AL, osteocalin and type I collagen mRNA in HDPCs in a dose dependent and not time dependent manner. Conclusion: CGRP plays an important role in promoting differentiation and calcification function of HDPCs
