BACKGROUND:When peri-implantitis occurs, the levels of interleukin-17 in the peri-implant sulcular fluid and soft tissues are significantly increased, and there is a positive correlation with the depth of the peri-implant probing. However, because of the dual effects of bone absorption and protection, the function of interleukin-17 in peri-implantitis remains controversial, which should be further studied. OBJECTIVE:To retrospectively analyze the correlation between peri-implantitis and interleukin-17. METHODS: The first author searched Wanfang, CNKI and Medline databases from 1991 to 2014 by using key words of “dental implants, peri-implantitis, periodontitis, Th17 cels, interleukin-17, cytokines” in Chinese or English. The functions of bone destruction and protection of interleukin-17 in peri-implantitis were reviewed, and interleukin-17 expression and correlation with the peri-implantitis were detected. RESULTS AND CONCLUSION:According to the inclusion and exclusion criteria, 46 articles from 241 articles are selected. The results show that, noninvasive detection of the variation of interleukin-17 levels in peri-implant sulcular fluid or blood is conducive to the monitoring of early diagnosis and treatment of peri-implantitis. At present, most researches show the relationship between interleukin-17 and peri-implantitis, and there is a positive correlation between interleukin-17 and peri-implant probing depth. But other researches suggest that interleukin-17 acts as protector for bones, and there is no statistic significance in the level of interleukin-17 receptor gene in chronic peri-odontitis and healthy subjects. Therefore, the correlation between peri-implantitis and interleukin-17 remains to be further studied.

Objective To study the effects of traditional Chinese medicine (TCM) five-tone therapy on nursing care of patients with irritable bowel syndrome (IBS).Methods By convenience sampling,a study was conducted among 100 patients with IBS.The patients were randomly divided into the control group and the intervention group,each group consisted of 50 patients.Patients in two groups were both treated with conventional drug and routine nursing care,but patients in the intervention group were intervened by TCM five-tone therapy for 3 months.Clinical efficiency of patients in two groups were assessed by Symptoms Check List-90 (SCL-90),Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD)before treatment and after 12-week treatment.Results The clinical efficiency in the control group and intervention group were 60％ (30/50) and 84％ (42/50) after intervention (P＜0.05).The scores of HAMA and HAMD after TCM five-tone therapy intervened were (5.24±1.15)points and (5.21±1.63) points,which were lower than the control group (8.32±1.42)points and (7.64±1.96) points (P＜0.05).The intervention group was scored lower than the control group in SCL-90 (P＜0.05).Conclusions TCM five-tone therapy may be more effective in decreasing the depression and anxiety of patients with IBS and alleviating their abdominal symptoms.

Objective To explore the effects of traditional Chinese medicine (TCM) five-tone therapy in combination with constitutional types of Chinese medicine based dietary intervention on patients with irritable bowel syndrome (IBS). Methods By convenience sampling, a study was conducted among 68 patients with IBS. The patients were divided into the control group and the intervention group by random digital table method, and each group consisted of 34 patients. Patients in two groups were both treated with conventional drug and routine nursing care, but patients in the intervention group were provided TCM five-tone therapy in combination with constitutional types of Chinese medicine based dietary intervention for 3 months. Patients in two groups were assessed by Chinese Medicine Constitution Questionnaire (CMCQ), Symptom Check List-90 (SCL-90), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) before treatment and after 12-week treatment. Results After TCM five-tone therapy in combination with constitutional types of Chinese medicine based dietary intervention, the number of IBS patients with pathological constitution types decreased in two groups, the number of patients with gentleness constitution increased to 8 and 25 separately in the control group and intervention group (P<0.05). After intervention, the scores of SAS and SDS in the intervention group were (40.73±8.27)points and (41.16±8.75)points respectively, which were lower than(48.36±7.53)points and(50.03±9.23)points of the control group, and the difference was statistically significant (P< 0.05). The intervention group scored lower than the control group in SCL-90, and the scores had significant differences between two groups (P<0.05). Conclusions TCM five-tone therapy in combination with constitutional types of Chinese medicine based dietary intervention may be more effective in adjusting pathological constitution to gentleness constitution of patients with IBS, alleviating their depression and anxiety and improving their physiological symptoms.

Objective To explore the risk factors in the prognosis of patients with severe multiple trauma related factors.Methods Ninety-three patients with severe multiple trauma(ISS score≥16 points) were selected as our subjects,who all hospitalized in the second hospital affiliated to Dalian medical University.Among of which,38 cases' ISS score was 16-25,and 55 cases' ISS score was higher and equal to 25.Clinical data and general information were recorded.ISS score,APACHE Ⅱ score and 6 h lactate clearance rate score were measured.Results Twenty-seven dead among these 93 cases and the mortality was 29.03％.There were significant differences in terms of ISS score,APACHE Ⅱ score,lactate level when entering ICU,6 h lactate level and 6 h lactate clearance rate between death patients (27 cases) and survival patients (66 cases) (t =9.846,9.812,7.112,7.012,9.831 ; P ＜ 0.001).In multiple organ dysfunction syndrome (MODS) patients,the mortality of ISS score:16-25 group was different from that of ISS score≥25 (15.78％ (6/38) vs.35.18％ (21/93),x2 =21.52,P ＜0.001).Among the 93 cases of severe multiple trauma,35 cases with MODS(37.6％ (35/93)),and 20 cases of which were dead(57.1％ (20/35)).There was statistic difference between MODS group(35 cases) and non-MODS(58 cases) in term of mortality(37.6％ (35/93) vs.12.1％ (7/58) ;x2 =21.52,P ＜ 0.001).Multivariate logistic regression analysis showed that the ISS score,APACHE Ⅱ score,6 h lactate clearance rate and MODS were independently prognostic correlation factors (P ＜ 0.05).Operating characteristic curve (ROC) showed that AUC of ISS score was 0.735 (95 ％ CI 0.629-0.842),of APACHE Ⅱ score was 0.888 (95％ CI 0.821 =0.956),of 6 h lactate clearance rate score was 0.951 (95％ CI 0.906 -0.997).Conclusion The factors of ISS score,APPCHE Ⅱ assessment,6 h lactate clearance rate,the occurrence of MODS are independent prognostic factors.

Attention deficit hyperactivity disorder (ADHD) has been associated with an elevated risk for obesity but this seems to be paradoxical to the fact that many youths with ADHD have symptoms of hyperactivity. People diagnosed with ADHD tend to have a high risk of developing undesirable diet habits and consequently have health related problems. However, less attention has been paid to obesity in ADHD while many efforts have been devoted to the prevention of childhood obesity in mentally normal people. Hence the purpose of this study was to explore the nutritional status and life habits of children and adolescents with ADHD (n = 76) based on degree of obesity by utilizing the Korean National Health and Nutrition Examination Survey (KNHANES) data from 2005–2013. As results the levels of blood pressure, total triglycerides and the fat intake relative to total energy intake in overweight ADHD group were higher than those in normal weight group. Interestingly, overweight ADHD subjects consumed significantly less amount of iron compared to normal weight ADHD subjects and the level of serum ferritin was lower in the overweight ADHD group (59.0 ng/mL) than in the normal weight ADHD group (47.9 ng/mL). After adjusting total energy intake, total vegetable consumption was 14.3% lower in overweight group compared to the consumption in normal weight group. These results indicate a plausible relationship of iron status and obesity in ADHD subjects but this relationship may not be specific to ADHD. A future study with case-control design is necessary to investigate the association of obesity, nutrient intake, and cognitive/mental status of ADHD.

BACKGROUND: The anatomical position of facial nerve is often abnormal because of the acoustical neuroma growth, so sometimes, the facial nerve injury is inevitable in the surgery treatment for acoustic neuroma.OBJECTIVE: To investigate the technology, veracity and practicality as well as the relationship between intraoperative monitorning and prognosis of facial nerve, and the clinical experiment was summed up of facial nerve function monitoring in 120 cases of acoustic neuroma surgery.DESIGN: Self-control observation.SETTING: Department of Neurosurgery, General Hospital of Chinese PLA.PARTICIPANTS: Totally 120 patients with acoustic neuroma who received treatment in the Department of Neurosurgery, General Hospital of Chinese PLA from May 1996 to February 2000 were recruited. Among them, 3 cases suffered from small-type acoustic neuroma (＜ 2 cm in diameter), 9 cases from middle-type acoustic neuroma (＞ 2 cm in diameter) and 108 from large-type acoustic neuroma (＞ 3 cm in diameter), including 1 case of bilateral acoustic neuroma and 1 cases of recrudescent acoustic neuroma; Suboccipital retromastoid approach was used in 119 cases and transretrolabyrinthine approach in 1 case.METHODS: American Viking-Ⅳ type monitor was used to monitor facial nervous function. When facial nervous function was monitored, recording electrode was put on orbicular muscle of eye, orbicular muscle of mouth or quadrate muscle of upper lip. When trigeminal motor branch was monitored, recording electrode was put on masseter muscle; When accessory nerve was monitored, recording electrode was put on trapezius muscle.Measurement of evoked auditory brainstem potential: recording electrode was positive electrode and was put at the midline in the frontal region (electroencephalogram 10-20 classification system). The recorded waveshape presented upward deflection. Reference electrode A1 or A2 and ground electrode were put in the midline of frontal pole (relevant to root of nose); Recording electrodes were all needle electrodes and were fixed with adhesive tape. Common stimulus intensity was 80 to 90 nHL, and 40 nHL noise was used in contralateral ear. Facial nerve was reserved following intraoperative monitoring. CT (enhancement scanning was necessary) or MRI was rechecked after operation to investigate the cutting degree of tumor; Facial nerve function was evaluated by H-B scoring (at 2 weeks, or 6 to 9 months following operation).MAIN OUTCOME MEASURES: Facial nerve function by H-B scoring before and after acoustic neuroma surgery.RESULTS: Totally 120 patients were enrolled, and no one dropped out.① Facial nerve anatomy was reserved in 117 cases; One case was failure to reserve facial nerve anatomy because pinnate facial nerve lay behind of acoustic neuroma, and electrical stimulation was not given at the beginning of neuroma resecting, then he received anastomosis of hypoglossal and facial nerve. Nerve of 2 cases was pulled and broken carelessly, and its two stumps were long enough that end-to-end anastomosis of facial nerve was performed with 7-0 absorbable suture following trimming. H-B score was Ⅳ to Ⅴ in the 6th month after surgery. ②Grade Ⅰ of facial nervous function at postoperative 2 weeks was found in 10 cases, grade Ⅱ in 57 cases,grade Ⅲ in 44 eases, grade Ⅳ in 4 cases, grade Ⅴ in 2 cases and gradeⅥ in 3 cases. ③Grade Ⅰ of facial nervous function at postoperative 9 weeks was found in 94 cases, grade Ⅱ in 18 cases, grade Ⅲ in 4 cases,grade Ⅳ in 1 case and grade Ⅵ in 2 cases.CONCLUSION: Spontaneous and evoked facial muscle electromyogram may be helpful to make sure the facial nervous position exactly and estimate the prognosis of facial nerve.

BACKGROUND:There is evidence that internal fixation through an anterior or posterior approach for treatment of severe kyphotic deformity in spinal tuberculosis exhibits good curative effects. However, few prospective, long-term fol ow-up case control studies are reported. OBJECTIVE:To investigate the efficacy and safety of cobalt al oy pedicle screw implantation for treatment of severe kyphotic deformity in spinal tuberculosis. METHODS/DESIGN:This is a prospective, single-center, self-control, open-label trial, which wil be performed at the Affiliated Hospital of Hebei University, China. Eighty-four patients with severe kyphotic deformity in spinal tuberculosis wil be included according to the diagnosis criteria. Among 52 patients with tuberculosis of the thoracic spine, 28 wil undergo surgery through a posterior approach, and 24 through an anterior approach. According to the Frankel Grade classification, grade C, D and E spinal cord function wil be assessed in 8, 31 and 13 patients, respectively. Surgery through a posterior and anterior approach wil be respectively performed in half of 32 patients with tuberculosis of the lumbar spine. Grade C, D and E spinal cord function wil be assessed in 7, 14 and 11 patients, respectively. The primary outcome measure of this study wil be the Cobb angle at the thoracic spine segments before and 2 years after surgery, which wil be used to evaluate the angle of the spine curvature at the thoracic segments. The secondary outcome measures wil be X-ray scan or MRI findings before and 2 years after surgery, which wil be used to evaluate vertebral fusion after internal fixation;and Frankel Grade before and 2 years after surgery, which wil be used to evaluate recovery of spinal cord function after injury. Other outcome measures wil include multiple logistic regression analysis results of the factors that influence patient's curative effects and the incidence of adverse events 2 years after surgery. The trial protocol has been approved by the Ethics Committee, Affiliated Hospital of Hebei University, China and wil be performed in strict accordance with the Declaration of Helsinki, formulated by the World Medical Association. Signed informed consent regarding the trial protocol wil be obtained from each participant. DISCUSSION:This study is to validate that cobalt al oy pedicle screw implantation shows precise curative effects in the treatment of severe kyphotic deformity in spinal tuberculosis and to analyze through what approach, posterior or anterior, internal fixation wil be more beneficial to surgery performance. The outcomes of this study wil provide objective long-term fol ow-up evidence for internal fixation treatment of severe kyphotic deformity in spinal tuberculosis in the clinic.

Autophagy dysregulation, mitochondrial dynamic abnormality and cell cycle re-entry are implicated in the vulnerable neurons of patients with Alzheimer's disease. This study was designed to testify the association among autophagy, mitochondrial dynamics and cell cycle in dividing neuroblastoma (N2a) cells. The N2a cells were cultured in vitro and treated with different concentrations of 3-methyladenine (3-MA). The cell viability was detected by methyl thiazolyl tetrazolium (MTT) assay. They were randomly divided into control group (cells cultured in normal culture medium) and 3-MA group (cells treated with 10 mmol/L 3-MA). The cell cycle was analyzed in the two groups 3, 6, 12, and 24 h after treatment by flow cytometry. Western blotting was used to evaluate the expression levels of mitofission 1 (Fis1), mitofusin 2 (Mfn2), microtubule-associated protein 1 light chain 3 (LC3), cell cycle-dependent kinase 4 (CDK4) and cdc2. The flow cytometry revealed that the proportion of cells in G(2)/M was significantly increased, and that in G0/G1 was significantly reduced in the 3-MA group as compared with the control group. Western blotting showed that the expression levels of Fis1, LC3, and CDK4 were significantly up-regulated in the 3-MA group at the four indicated time points as compared with the control group. Mfn2 was initially decreased in the 3-MA group, and then significantly increased at 6 h or 12 h. Cdc2 was significantly increased in the 3-MA group at 3 h and 6 h, and then dropped significantly at 12 h and 24 h. Our data indicated that 3-MA-induced suppressed autophagy may interfere with the cell cycle progression and mitochondrial dynamics, and cause cell death. There are interactions among cell cycle, mitochondrial dynamics and autophagy in neurons.
