Objective: ①To detect the concentrations of interleukin 1?(IL 1?) and prostaglandin E 2 (PGE 2) in periapical exudates in the patients with acute or chronic periapical periodontitis; ② To examine their correlations with clinical and radiographic findings of the involved teeth.Methods: The volume of periapical exudates was quantified using the standard paper point sampling method; the concentration of IL 1? and PGE 2 was detected using enzyme linked immunosorbent assay(ELISA) or radioimmunoassay(RIA) in 40 cases with acute and in 40 with chronic periapical periodentitis. Results: ①The volume(?l) of the exudates in the cases with acute periapical periodontitis and chronic were 27.10?15.70 and 3.12?2.88( P

Objective To observe the diameters of macular hole and destroyed boundary line between inner and outer segment (IS/OS) of the photoreceptors and the correlation with the visual acuity in patients with idiopathic macular hole(IMH). Methods The clinical data of 39 eyes (37 patients) with IMH were retrospective analyzed. All the patients had undergone the examinations of visual acuity (Snellen chart), intra-acular pressure, ocular fundus (indirect ophthalmoscope), and Fourier-domain optical coherence tomography (FD-OCT) whose speed was 27 000 A scan/s, area was 6.0 mm×6.0 mm, and the mode was 512×128. The diametres of macular hole and destroyed IS/OS, and the correlations with visual acuity were detected. Results The mean IogMAR was 0.99±0. 44 (ranged from 0. 15 to 2.00), the mean diameter of macular holes was (942.0± 348. 4)μm(ranged from 171 to 1491 μm), and the mean diameter of IS/OS disruption was (1870. 35±673.2) μm(range from 463 to 3176 μm). There was a significant correlation among the diameter of the macular hole, the diameter of the IS/OS disruption, and IogMAR in IMH (P= 0. 038, 0. 002, 0. 000). In eyes with closed macular hole after surgery, the IogMAR and the diameter of the IS/OS disruption had a significant decrease. Conclusion Using FD-OCT the photoreceptor changes can be visualized in vivo. The abnormality in the IS-OS boundary line appears to be involved for a much larger area beyond the macular hole itself, and persists there with small size even after the maeular hole closure surgery.

Objective To investigate the cognition, self-management and quality of life of osteoporosis in elderly patients, and to provide the basic theory for health education in elderly patients with osteoporosis.Methods 565 elderly patients with osteoporosis in our hospital from May 2012 to Mar.2015 were enrolled.The cognition, health beliefs, self-efficacy and quality of life were investigated by questionnaires and analyzed by Microsoft Office Excel 2007.Results 565 osteoporosis patients, the symptom score was (15.6±2.0), and the score was lower in sporting knowledge (4.3 ± 1.8) than in calcium knowledge (5.7 ± 1.5) (t=2.784, P=0.011).Health beliefs score was (139.0±9.6), containing exercise benefits score of (21.5±3.1), exercise barriers score of (13.8±3.9), susceptible score of (19.4±4.2), serious score of (18.8±4.4), health motivation score of (25.0±3.0), calcium intake benefits score of (20.7±3.5) and calcium intake disorder score of (19.8 ± 4.0).Self efficacy score was (63.7 ± 19.4), containing exercise efficacy score of (58.6 ±18.7) and calcium efficacy score of (69.2± 18.5).Quality of life score included the general health (16.5± 2.9 score), social function (5.8 ± 1.3 score), vitality (14.8 ± 3.2 score), mental health (20.7± 4.2 score), physiological function (20.5 ± 4.1 score), physiological role limit (6.3 ± 1.6 score), emotional role limit (5.1 ± 1.3 score) and body pains (4.3 ± 1.8 score).Conclusions The score in cognitive function is low in elderly osteoporosis patients.It's useful to improve elderly osteoporosis awareness and quality of life by carrying out relative education.

0. 05). No significant difference was found in maternal and neonatal complications between the ANCA( + ) and ANCA(－) subgroups in S-PE subjects. But those 4 cases who developed renal function insufficiency patients were ANCA( + ). Conclusions ANCA might be associated with renal diseases in preeclampsia women, and further studies is required to determine whether ANCA is involved with the pathogenesis of preeclampsia.

In recent years, the prevalence of cardiovascular disease (CVD) in China has been increasing year by year, and it has become a major public health concern. The prevention and control of chronic CVD is inseparable from effective early screening. However, due to the imbalance in the level of economic and social development in various parts of China, the universality and accessibility of screening in some areas still need to be improved. The fundus retinal blood vessel is the only vessel in the whole body that can be directly observed. Studies have found that its morphological and functional changes are related to the occurrence and development of many CVD, and it has the potential to become a tool for assessment and prediction. This review intends to introduce the research progress of retinal blood vessels in the evaluation and prediction of cardiovascular disease in recent years.

Objective To summarize the clinical outcome of direct trans-scleral drainage by puncture with 25G needles in the external-route surgeries for primary retinal detachment. Methods Fifty-four consecutive cases of primary retinal detachment were treated by external-route surgeries. The subretinal fluid of 23 cases was drained by direct scleral puncture with 25G needles (25GND group), the other 31 cases underwent the conventional scleral incision and drainage(CD group). Postoperative complications, the single-operation retinal reattachment rate and functional outcome were recorded.Results Subretinal fluid was adequately drained in all cases. there was no significant difference in the single-operation retinal reattachment rate between 25GND and CD groups. In comparision to CD, 25GND significantly decreased postoperative complication rate (?2=4.729,P

In this article,the oral medicine laboratory teaching of non-oral medicine international students was analyzed and summarized. Teaching plan should be made in accordance with the aptitude of students and goal of training. We used many teaching methods such as multimedia teaching,demonstration with teeth in vitro,etc and acquired good teaching effects. It gives us many experiences for the future teaching.

ObjectiveTo explore the correlation between the prevalence of benign prostatic hyperplasia(BPH) and metabolic syndrome (MS)in the army elderly.Methods Totally 1 230 veterans (aged 70 years and over) from 26 military sanatorium in Shijiazhuang city were studied.The prevalence of BPH and MS was calculated.ResultsThe prevalence of BPH among the elderly was 77.0％.There was a trend of increase in the prevalence of BPH with increasing age (x2 = 50.4,P＜0.01).The prevalence of MS among the male elderly was 19.6％.MS was a risk factor for BPH(x2 =24.2,P＜0.0001).ConclusionsMS may be one of risk factors for the prevalence of BPH.

BACKGROUND:Closed reduction and interlocking intramedullary nailing can protect blood supply of fractured bone,decrease infection and promote bone healing.which is becoming the first choice for treating femoral shaft fracture However,it is difficult to conduct in closed reduction and keep stabilization of fractured bone.OBJECTIVE:To explore the curative effect of closed reduction and interlocking intramedullary nailing in treating femoral shaft fracture with assist of rubber tourniquet 360°elastic fixation METHODS:From May 2008 to November 2009,18 patients(14 males,4 females;aged 18-65 years)with closed femoral shaft fracture were treated at the Dongguan Hospital of Traditional Chinese Medicine.Body skin was protected by cloth,elastic rubber tourniquet was doubled and 360°wrapped around the fractured bone with the length of 10 cm from up and down.Supracondylar femur was reamed by Kernig-needle;fractured bone was dealt with countertraction and horizontal rotation.Another assistant compressed the fractured bone according to the displacement of fracture,which contributes to bone fracture reduetion and interlocking intramedullary nailing.RESULTS AND CONCLUSION:All 18 patients were followed up postoperatively,no case was found with skim necrosis and damage of nerve and blood vessel.16 cases were bone union with excellent 15 cases,fine 1 case;2 cases were still being followed up.Callus was firstly found 1 month after operation and was obviously found in 3e months postoperatively The result suggested that the treatment of closed reduction and interlocking intramedullary nailing with assist of rubber tourniquet360°elastic fixation is a simple and applicable approach.which reduces the interruption of blood supply for fractured bone and closed reduction gets good result,which reduces the chance of open reduction.
