Four cases of rejection reactions after acupoint embedding with chromic catgut as well as the diagnosis and treatment course were reported to reveal the importance of rejection reaction and its generality. Besides, the cause and mechanism were discussed. By combining the treatment experience, it was recommended to replace the catgut with third-generation absorbable medical suture, which could prompt execution of standardized manipulation of acupoint embedding.

0.05).(4)Differences in Apelin level were found between the NC group and the CHD group both before and after angiography(90.25?2.96 ?g/L vs 77.04?3.89 ?g/L in arterial blood and 87.83?3.34 ?g/L vs 75.14?3.16 ?g/L in venous blood before angiography;91.25?2.04 ?g/L vs 78.11?2.84 ?g/L in arterial blood and 90.79?2.58 ?g/L vs 77.43?2.38 ?g/L in venous blood after angiography;all P values

OBJECTIVE To strengthen the self-protection consciousness of supply office staff to reduce the occupationol infection.METHODS From Sep 2006 to Aug 2007,97 supply office persons in 8 third-level hospitals and 2 second-level hospitals were carried on the related questionnaire survey.RESULTS 85.6% Of the staff were contaminated by blood,body fluid,secretion and the excreta,74.2% of them were contaminated for many times.Sharp instrument injunry occurcd among 77.3% of the staff,in which 14.4% were injured more than 5 times,About the knowledge of prevention,43.3% was familiar,47.4% only heared about them but not familiar and 9.3% never heared it.CONCLUSIONS The supply office staff is the high dangerous infection crowd,who are the suscepitable population of the sharp instrument injury.It is important to adopt the universal prevention and the standard preventive measures to reduce occupational infection occurrence.

The present valuation of experimental teaching effect can not adapt to the needs of the experimental reform and develpoment due to its deficiency. After setting up the experimental curriculum,A Multivariate method has been developed to evaluate students’ experimental ability from their innovating,operating,expressing ability and scientific quality.

OBJECTIVE:To observe the clinical efficacy of herbal desensitizer in the treatment of dentine hypersensitivity. METHODS: 126 patients with dentine hypersensitivity were enrolled: 64(a total of 172 diseased teeth) were randomly assigned to trial group to be treated with herbal desensitizer,and 62(158 diseased teeth) to control group to be treated with sodium fluoride glycerin. The clinical effects observation was scheduled immediately,3 and 6 months after the treatment. Then the results were analyzed using statistics software.RESULTS: Significant differences were found between the trial group and the control group in clinical effects (P

Objective To study the changes of plasma interleukin-13 (IL-13) in patients with acute cerebral stroke and its effects in the cerebral inflammatory reactions. Methods The levels of plasma IL-13 measured in 50 patients with acute cerebral infarction (CI group) and in 30 patients with cerebral hemorrhage (CH group) using enzyme-linked immunoabsordent assay(ELISA) were compared to the control A (with the risk factors of stroke) and control B (normal group).Results As compared with the controls (control A: 28.0?3.2; control B: 26.4?2.7), the levels of plasma IL-13(pg/ml) were increased in three periods in the CI group (37.6?6.2;45.2?10.1;41.3?8.3) and CH group (36.6?4.9;45.3?8.9,38.1?5.6) ( P

Objective To investigate the correlation between moderate hypoxia and maliglant transformation of colon carcinoma cell line HT-29.Methods Hypoxic conditions were produced according to p(O2)of tumor in vivo.The heterotypic adhesiveness of HT-29 cells was detected by MTT assay.Their reaction to the hypoxic environment was determined via invasion across a Matrigel-coated Transwell filter.At 0,6,12,24 and 48 h after hypoxia,MMP-2/9 activities were assessed by gelatin zymography,and osteopontin mRNA and protein levels by RT-PCR and Western blot respectively.NF-?B/p65 levels in nucleus was measured by Western blot after extraction of nucleic protein.Results After 24-hour moderate hypoxia,the heterotypic adhesiveness and invasive capacity of HT-29 cells were significantly enchanced.MMP-2,MMP-9 activities under moderate hypoxia for 6 h showed no significant change as compared with that under normoxia,then gradually up-regulated and reached the peak at 24 h.They showed no significant difference between 24 h and 48 h after hypoxia.The expression trend of osteopontin mRNA,protein and NF-?B/p65 protein in nucleus was similar to that of MMP-2,MMP-9 under moderate hypoxia.Conclusion Moderate hypoxia could induce maliglant transformation in HT-29 cells through enhancing heterotypic adhesiveness and invasive capacity and upregulating MMP-2,MMP-9 activities.OPN-NF-?B may be an important regulatory pathway besides HIF-1 under hypoxic condition,which involves maliglant phenotype induced by moderate hypoxia.

Objective To retrospectivly analyze the value of Pap smear,liquid-based cells, colposcopy and colposcopic cervical biopsy in the diagnosis of cervical cancer. Methods 116 cases of cervical cancer were retrospectively analyzed, and the value of Pap smear,liquid-based cells ,colposcopy,and colposcopic cervical biopsy in the diagnosis of cervical cancer were investigated. Result 116 patients were pathologically diagnosed with cervical cancer before and after surgery. Pap smear was performed for 30 patients (25.9%) ,and 10 patients (33.3%) were detected with HSIL. Liquid-based cells was performed for47 patients (40.5%) ,and 25 patients (53.1%) were detected with HSIL. Colposcopy was performed for 99 patients (85.3%), and 75 patients (75.8 % ) were detected with HSIL or invasive cancer. Preoperative colposcopic biopsy was performed for 99 patients, and the pathological coincidence rate was 94.9%. There was no significant difference statistically between two cytology screening ( P ＞ 0.05 ). There was significant difference statistically between liquid-based cells and colposcopy ( P ＜ 0.01 ). There were significant differences statistically among liquid-based cells,colposcopy ,and colposcopic cervical biopsy ( P ＜0.01 ). Conclusion Cytology, colposcopy, colposcopic cervical biopsy could not be individually more complete and accurate detection of cervical cancer. Colposcopy,colposcopic biopsy than cytology had higher accurate rate of diagnosis of cervical cancer. A reasonable combination of multiple detection methods could improve the diagnostic accuracy of cervical cancer.

Objective To investigate the pollution status of heating-ventilating-air conditioning(HVAC) systems in Shenyang public place. Methods The dust samples were collected and examined from the HVAC system in twelve hotels and ten shopping malls in Shenyang in March-June, 2004. Results Among HVAC systems in Shenyang public buildings, 71.51% of them were moderately polluted and 27.37% were seriously polluted. The rate of serious pollution of hotels was higher than that of shopping malls, the volume of dust in the air pipes in hotels was lager, but the amount of bacteria and fungi was less than that of shopping malls. Conclusion The HVAC systems of Shenyang public buildings have been seriously polluted.

BACKGROUND:Open reduction and internal fixation has been confirmed to treat posterior Pilon fracture,but choosing which fixation scheme is still under discussion.OBJECTIVE:To explore the biomechanical properties of posterior Pilon fracture after repaired by two different fixation methods,thus providing reference for selecting an appropriate fixation scheme.METHODS:Twenty right artificial femurs were randomized into two groups A and B,and the models of posterior Pilon fracture were established based on its characters and classification.The group A received with 5 holes distal tibial posterior locking plate fixation,and the group B underwent two 3.5 mm of cortical screws from back to front bicortical fixation,followed by placed in the InstronElectroPulsE3000 universal electronic static and dynamic materials testing systems,vertical speed loaded until internal fixation failure,the loading was recorded when different steps appeared.RESULTS AND CONCLUSION:(1) After loading,none of groups presented with screw bent or broken.(2) The axial load when appeared with 0.5,1.0,1.5,and 2.0 mm steps in the group A was higher than that in the group B,and the axial load significantly increased with fracture fragment displacement increasing (P ＜ 0.05).(3) The biomechanical test shows that the distal tibial posterior locking plate fixation is better than screws in the treatment of posterior Pilon fracture.
