This study was aimed to explore the tic disorders ( TD ) pathogenesis induced by chronic rhinitis . A total of 400 TD children were all investigated with self-made TD general questionnaire , Yale Global Tic Severity Scale ( YGTSS ) , TD diagnostic criteria by DSM-IV , chronic rhinitis diagnostic criteria by Zhu-Fu-Tang Textbook of Pediatrics ( 7th edition ) . A total of 258 TD children accompanied with chronic rhinitis were screened . Levels of peripheral blood T lymphocyte subsets , immunoglobulins , IL-6 , TNF-α and other related immunological indexes were detected to analyze pathogenesis. The results showed that the nose movement symptom scores of TD children with rhinitis were higher than the score of TD children without rhinitis . The score of arm-lifting and hand movement in TD children with rhinitis was lower than the score in the TD children without rhinitis . And the YGTSS score of TD children with rhinitis was higher than TD children without rhinitis. Compared with TD children without rhinitis, the level of peripheral blood T lymphocyte subsets in TD children with rhinitis was obviously reduced ( P < 0 . 05 ) . Compared with TD children without rhinitis , the level of immunoglobulins in TD children with rhinitis was slightly reduced . The level of IL-6 in TD children with rhinitis tended to increase , but the level of TNF-α tended to reduce . It was concluded that chronic rhinitis is one of the factors to induce TD .

AIM To explore the effects of trip-tolide on endothelin-1 and its gene expression in lung of asthmatic guinea-pigs. METHODS The contents of ET-1 in lung of asthmatic guinea-pigs were measured with radioimmunoassay, and the expressions of ET-1, ETA, ETB and ECEmRNA with reverse transcription DNA polymerase chain reaction (RT-PCR). RESULTS 0 All of the indexes were increased after guinea-pigs were induced asthma. At the 4th hour after first induction of asthma, ET-1 reached the top, but at the 2rd hour, ET-1mRNA, ETAmRNA and ECEmRNA were markedly higher than control group (P

Local recurrent nasopharyngeal carcinoma(NPC) presents a troublesome challenge to radiation oncologist. Reirradiation is the primary modality nowadays. However, clinical data on reirradiation are still relatively scarce. This article summarized the treatment advances and the clinical characteristics associated with relapse of NPC, and reviewed the outcomes of different radiation techniques in the management of recurrence of NPC, i.e. conventionalradiotherapy, stereotactic radiotherapy, brachytherapy, three-dimensional conformal radiotherapy and intensity modulate radiotherapy, or some combination of above in recent years.

Objective To evaluate the effects of sevoflurane on proteome in the cortices of neonatal rats.Methods Thirty neonatal rats at postnatal day 7 (6 rats each litter,5 litters in total) were randomly assigned into 2 groups (n =15 each):control group (C group) and sevoflurane group (S group).The rats were exposed to air and 1.8 ％ sevoflurane for 4 h in C and S groups,respectively.One rat from each litter was chosen in each group at the end of anesthesia and the puncture needle was inserted into the left ventricle via the chest wall.Arterial blood samples were then collected for blood gas analysis and for determination of blood glucose.One rat from each litter was sacrificed in each group at 3 and 72 h after the end of anesthesia,and their cortices were then dissected.Two-dimensional differential in-gel electrophoresis (2-D DIGE) was used to identify patterns of protein expression in cortices cross-labeled with different CyDyes.The differentially expressed proteins were analyzed by using matrixassisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS).Results Acid-base imbalance,anoxia or lycopenia were not found at 3 h after the end of anesthesia in both groups.The analysis showed there were 6 differentially expressed proteins at 3 h after the end of anesthesia in S group compared with C group.Among the 6 proteins,the expression of 4 proteins (class 2 c beta-tubulin,neuron-specific class Ⅲ beta-tubulin,CRMP-1 and CRMP-4) which belonged to cytoskeleton/neuronal growth proteins was down-regulated,the expression of 1 protein (ATP synthase beta subunit) which belonged to hydrolyses and transferases was down-regulated,and the expression of 1 protein (guanine nucleotide binding protein beta1) which belonged to signal transduction proteins was up-regulated (P ＜ 0.05).No significant changes in protein expression were identified at 72 h after 1.8％ sevoflurane anesthesia (P ＞ 0.05).Conclusion 1.8％ sevoflurane-induced 4 h anesthesia can induce short-time changes in the expression of proteins which are related to neuronal migration,differentiation,energy metabolism and signal transduction in cortices of neonatal rats,which may contribute to its neurodegenerative effects in brains of rats during the development period.

Objective To investigate early renal damage of chronic hepatitis B (CHB) patients and the risk factors related to their renal function. Methods CHB patients who visited the second people’s hospital but did not receive systemic treatment were enrolled in our study. Those who visited for general check-up with no hepatic findings during the same period were selected as control group. Glomerular filtration rate (GFR) of all the participants were estimated by simplified MDRD equation and CKD-EPI equation (designated as M-eGFR and C-eGFR respectively). Influence factors of eGFR were statistically analyzed. Results In the total 528 cases in CHB group, 88 (16.67%) and 62 (11.74%) suffered declined M-eGFR and C-eGFR respectively. By contrast, 10 (8.77%) and 6 (5.26%) cases in the total 114 cases in control group present declined M-eGFR and C-eGFR ac?cordingly. Percentages of renal function impairment, estimated by both M-eGFR and C-eGFR, were higher in the CHB group than those in control group. The difference was statistically significant (χ2=4.518, P<0.05;χ2=4.156, P<0.05). Multiple linear regression analysis indicated that age, HBsAg and body mass index (BMI) were risk factors of M-eGFR while age, HBsAg, gender and serum albumin were risk factors of C-eGFR. On the other hand, HBV-DNA and HBeAg were not risk factors for M-eGFR or C-eGFR. Conclusion HBV infection can lead to early renal damage. Age and HBsAg are main risk factors of renal function impairment. Therefore, renal function should be scrutinized in CHB patients.

Objective To evaluate emergency nursing methods to permanent pacemaker patients with severe complication and acute hemodynamic changes during implantation. Methods The emergency nursing methods were analyzed retrospectively in 9 of 2 027 patients over 6 years, who had serious complication occurred during the pacemaker implantation Results There were 4 patients with pneumothorax, 2 with pericardial tamponed, 1 with ventricular fibrillation and 2 with acute left ventricular failure in 9 patients (0.4%). Observed the changes of symptoms and signs carefully,found the severe complications at the first time and performed the specific nursing based on different kinds of conditions and improved the prognosis of these patients. Conclusions The serious complications during the implantation of permanent pacemaker were life-threatening, and the specific nursing scheme to different types of complications could increase the successful rate of emergency service.

Objective To analyze the morphological matching rate with a digital image recognition system in pre-and post-orthodontic treatments,and to provide forensic dentistry evidence for individual identification.Methods High-resolution digital images of the palatal rugae were taken under particular conditions from each patient in pre-and post-orthodontic treatments.Features of each digital image were extracted using a digital image recognition system and collected in the palatal rugae database.Data of the palatal rugae werematched by MATLAB software system.Results From the matching results,the accuracy rate of individual identification of orthodontic patients was 100％.The accuracy rate in matching palatal rugae patterns in pre-and post-orthodontic treatments was 95.67％.The results were statistically significant with P＜0.05.Conclusion Palatal rugae pattern is highly individual-specific.The morphologyofpalatal rugaecould bechangedby theorthodontic treatment,however,these changes may not greatly influence individual identification in forensic dentistry,providing a new potential to individual identification.

Objective To investigate the impact of compliance and quality of life of psychological intervention for cancer patients and their primary caregivers,as well as the correlation between the psychological issues of patients and their primary caregivers.Methods The enrolled patients were randomly divided into intervention group and control group.The patients in intervention group were given to standardize anti-tumor therapy,while the patients and their primary caregivers were given psychological intervention once a week.The patients in the control group only received standard anti-tumor therapy.By TDL determination of quality of life,anxiety rating scale (SAS) and self-rating depression scale (SDS),in front of the psychological intervention after 8 weeks of intervention,the two groups of patients and their primary caregivers were questionnaired,and recorded the completion of the treatment plan.By SPSS 12.0 software,the statistics were completed.Results 51 cases in intervention group and 38 cases in control group were able to complete the number of people expected to treat there was a statistically significant (P ＜ 0.05).TDL determination and quality of life scores in intervention group patients and their primary caregivers were significantly higher (P ＜ 0.05).SAS and SDS score in intervention group patients and their primary caregivers were significantly lower than control group (P ＜ 0.05).Conclusion The effective psychological intervention to cancer patients and their primary caregivers during the treatment of patients could improve the compliance of cancer patients,the quality of life of cancer patients and their primary caregivers.The psychological problems between the patients and primary caregivers are positive correlation.
