Objective To observe the clinical efficacy of medicinal moxibustion plus oral administration of Chinese medication in treating chronic eczema.Method Seventy patients with chronic eczema were randomized into a treatment group and a control group, 35 cases in each group. The treatment group was intervened by medicinal moxibustion plus oral administration of Chinese medication, while the control group was by conventional moxibustion plus Chinese medication. The Scoring Atopic Dermatitis Index (SCORAD) was observed before and after treatment, and the clinical efficacies were compared.Result The total effective rate was 72.7% in the treatment group versus 56.3% in the control group, and the difference was statistically significant (P<0.05). The SCORAD scores were significantly changed after treatment in both groups (P<0.05). After treatment, the SCORAD score of the treatment group was significantly different from that of the control group (P<0.05).Conclusion Medicinal moxibustion plus oral administration of Chinese medication is an effective method in treating chronic eczema.

Objective To explore the protective effect of rhG-CSF given intranasally on cerebral infarct rats by observing the neurological dysfunction and the expression of Fas ligand (FasL) in hippocampus of cerebral infarct rats.Methods Middle cerebral artery occlusion(MCAO) model rats were established by nylon strand,reperfuse 2 hours later,and give rhG-CSF through subcutaneous and intranasal way.The rats were divided into the nermal group,the sham-operated control group(sham),MCAO group,MCAO+NS given intranasally group(NS),MCAO + rhG-CSF given subcutaneously group,and MCAO + rhG-CSF given intranasally group each group had 6 rats. At the time of 3d after reperfusion,neurological severity scores (NSS) test was performed and the expression of FasL was detected via immunohistochemical staining in collateral hippocampus. Results Neurological dysfunction appeared in all groups except for the normal and the sham group. The dysfunction of the MCAO and the NS group was the most serious,the NSS was the highest(10.20±1.85,10.30±1.76),the number of FasL positive cells was the most(41.17±3.25,41.00±2.76),and there was no obvious difference between the two groups ( P ＞0.05);the NSS and FasL positive cells decreased in the subcutaneous group(5.67±1.32,P ＜0.01;32.67±1.97,P ＜0.01) and decreased further more in the intranasal group(4.00±0.93,P ＜0.05;19.50±1.05,P ＜0.01).Conclusions rhG-CSF given intranasally can relieve the neurological dysfunction of cerebral infarct rats,and brain cells are thereby protected by resisting the expression of FasL.

Objectives: To investigate the occlusion features in thre e dimensions in patients with temporomandibular disorders(TMD). Methods: Occlusal casts were obtained from 23 asymptom volunteers and 101 TMD pati ents and were analyzed in three dimensions by scores vertically, mesio-distally and labial-or buccal-lingually. Bilateral TMJs of each TMD patient was examin ed with Schuller's radiograph and tomograph, the sounding TMJs were examined wit h arthrography. The relationship between occlusion scores and the changes shown in X-ray images were analyzed. Results: 66.3% TMD patients had abnormal occlusion in vertical direction.Abnormal occlusion in vertical directio n was correlated with TMD symptoms(P 0.05 ). Conclusion: Abnormal occlus ion in vertical direction is correlated with TMD symptoms.

Objective: To investigate the expression and distribution of G protein and protein kinase C (PKC) under the mechanical pressure in rabbit mandibular condylar chondrocytes (MCCs) and to study the role of G protein in PKC signalling pathway. Methods:MCCs from two-week-old New Zealand rabbits were cultured. After treatment under continuous pressure of 90 kPa for 60 min or 360 min by hydraulic pressure controlled cellular strain unit, the expression of G?q/11 protein was examined by Western Blot. The expression and distribution of PKC was observed by immunocytochemical staining. Results:Gaq/11 protein in MCCs treated by 90 kPa for 60 min and 360 min was increased by 163.7% and 65.8% respectively(P0.05). PKC in control cells distributed uniformly in the cytoplasm. After been pressed under 90 kPa for 60 min,PKC translocated to the membrane and, partly,into nuclei. When the pressure prolonged to 360 min, PKC distributed uniformly again in cytoplasm. By treatment of G protein inhibitor, the translocation of PKC under 90 kPa of 60 min was not observed. Conclusion:Feasible pressure may promote G protein expression and activate PKC. The activation of PKC signalling pathway is mediated by G protein.

Objective To analysis the fresh motherwort capsule treatment of postpartum uterine hemorrhage clinical value.Methods100 cases of postpartum uterine hemorrhage patients of our hospital from January 2016 to December 2016 were selected as the research object, the control treatment, use contractions observed group of using fresh motherwort capsule combined contractions for treatment.Check after drug treatment in patients with uterine instauration and clinical curative effect.ResultsAfter five days, two groups of patients with postpartum uterine instauration is close, there was no statistically significant difference.After 14 days, observation group of patients with uterine instauration was significantly better than the control group, there was statistically significant difference (P< 0.05);Observation group of patients treatment of cure rate (76.0%), and total effective rate (96.0%) were significantly higher than control group (56.0%, 88.0%), statistically significant difference (P< 0.05).ConclusionFresh motherwort capsule in the treatment of postpartum uterine hemorrhage has significant clinical efficacy, can promote the patients with uterine instauration, has significant clinical value, worthy of popularization and application.

Objective To explore the role of problem-based learning(PBL) nursing ward round on critical thinking capacity of nurses from surgical departments. Methods All nurses from surgical depart-ments were randomly divided into the experimental group(86 nurses) and the control group(85 nurses) by drawing lots. Objects from the experimental group received PBL nursing ward round training twice a week for 8 months, while those from the control group used the traditional nursing ward round training. The influ-ence of the different teaching methods on the critical thinking capacity of the nurses was assessed before and after the training, using critical thinking disposition inventory-Chinese version (CTDI-CV). Results Total critical thinking capacity was improved significantly in the experimental group after the training. All sorts of critical thinking characteristics were strengthened in different degree. Conclusions PBL nursing ward round training can effectively facilitate the critical thinking capacity of surgical nurses.

Objectives: To investigate the effects of cent ra l disordered occlusion on the thickness of TMJ disc. Methods:The thickness of temporomandibular joint disc was measured in 5 cadavers with centr al disordered occlusion, including secondary malocclusion caused by loss of post erior tooth for a comparable long time with collapse of neighbor teeth and supra -eruption of its antagonized tooth, the supra-erupted third molar resulted fro m lack of antagonized tooth for a comparable long time and individual posterior tooth cross bite or reverse cross bite asymmetrically. Other 7 cadavers without central disordered occlusion served as controls. All samples were examined histo logically for the TMJ disc thickness. Out of 18 New Zealand rabbits, aged 5 mont hs, 9 were treated orthodontically to pull the first premolar move medially, occ luding with its opposite un-coincidently, central disordered occlusion was grad ually induced. The other 9 rabbits served as blank controls. The TMJs were sampl ed 3 months after beginning of the experiments, stained with HE and observed und er microscope. Results: In both cadavers and animals, the TMJ di sc was found much thicker in central disordered occlusion group than that in the control group (P

Objective:To investigate the effect of tooth wear on the morphological features of mandibular first molars. Methods:15 extracted mandibular first molars with tooth wear and 15 without wear were investigated. Data about the morphological features of tooth were collected through the general measurement and the image measurement by electronic meter. Results:①In non-tooth-wear group, mesiodistal width of tooth was greater than buccolingual width(P0.05); ②The vertical distance between the lowest point of pulp chamber roof and occlusal surface in non-tooth-wear group was greater than that in tooth-wear group(P05); ④The distance between distolingual pulp horn and distal proximal plane was greater than that between mesiolingual pulp horn and mesial proximal plane in both two groups(P0.05). Conclusion:For different parts of tooth, the effect of tooth wear differs. As for mandibular first molars, the distal part of occlusal surface and the buccal part of distal proximal plane are susceptible to tooth wear, which is mainly due to occlusal factors and the features of biomechanical system.
