BACKGROUND: Palatal implant could be an effective type of anchorage that can afford long-term stress, and bone thickness and bone density of the implant placement will affect the success of the implant stability. Presently, actinoscopy commonly used in stomatological clinic cannot provide the precise information of palatal bone thickness and bone mineral density such as toroidal slide plate photograph and skull lateral projection. OBJECTIVE: To measure the thickness and density of median palatine suture, and to provide the consultation for implant anchorage using spiral CT. DESIGN, TIME AND SETTING: A measurement study was performed at the Medical Imaging Center, First Affiliated Hospital of Xinjiang Medical University from July to December in 2008 PARTICIPANTS: The sample consisted of 194 cases undergoing 64 slice CT at the Medical Imaging Center of First Affiliated Hospital of Xinjiang Medical University, including the scope of the hard palate and maxillary dentition. They were aged from 18 to 50, and divided into three groups by age, 18-30-year-old group, 31-40-year-old group, and 41-50-year-old group. METHODS: Measurement of palatal raphe area first three-dimensional reconstruction of images at up to nasion plane centerline, whichever was determined as a reference surface plane, selection one point on incisor cervix in this line, to measurement of the available palatal bone height; sagittal views were selected at 6 mm dorsally from the incisive canal. The available bone height was defined as the distance from the palatal baseline (lower cortical border of the palate) to the nasal cavity (upper cortical border of the nasal cavity). Bone mineral density can also be measured at the same site, take the average of the cortical and cancellous bone. MAIN OUTCOME MEASURES: The palatal bone thickness and bone thickness density were measured at 6 mm dorsally from the incisive canal. RESULTS: Male in the palatal bone thickness and bone mineral density were significantly higher than female (P < 0.05); there were no significant difference between Han and Uygur (P>0.05). In different age's group of men and women, the palatal bone thickness and bone mineral density showed no statistical difference (P > 0.05). Age, palatal bone thickness and palatal bone mineral density had no significant correlation. CONCLUSION: Spiral CT can be used in different parts of mandible thickness and density measurement and analysis. The palate raphe can be implant as orthodontic anchorage if it measured exactly.

Objective To explore the effect of separate management of income and expenditure (SMIE) on standard community healthcare services. Methods Health management records of 137 community health service ( CHS) institutions in Beijing during 2006 and 2009 were retrospectively analyzed. Paired t test was used to compare annual healthcare services at urban and rural areas before or after SMIE was adopted. Results The standard community healthcare services was reduced from 1 081 965. 53 to 971 793. 98 at urban areas and from 157 492. 23 to 149 305. 25 at rural areas (P >0. 05). Urban healthcare center-based standard services was decreased from 59. 94% to 52. 14% (P < 0. 05 ); while out-hospital services were increased from 13. 50% to 18. 88% (P<0. 05). In urban areas,standard services for women healthcare, chronic disease profiling, health education and information management were significantly increased (I <0. 05). However,Temporary observation and endemic disease prevention and treatment were the main job of rural healthcare. Conclusions SMIE in CHS institutions could accommodate to the need of health management, supporting policies should be further improved.

ObjectiveTo investigate the cause,diagnosis and treatment measures of neonatal pneumothorax.MethodsThe clinical data of 98 cases with neonatal pneumothorax in our hospital from Mar 2005 to Mar 2010 were reviewed retrospectively.ResultsThere were 27 premature neonates and 71 full-term neonates in the 98 cases.Ten cases were spontaneous pneumothorax and 88 cases were non spontaneous pneumothorax.After the treatnent of primary disease,pleural aspiration,chest drainage and mechanical ventilation,88 cases were cured,8 cases were improved and 2 cases died.ConclusionNeonatal pneumothorax is related with cesarean section,improper use of endotracheal intubation,meconium aspiration,premature hyaline membrane disease using pulmonary surfactant and ventilator therapy.Most pneumothorax is due to lung disease.The prevention of preterm birth and asphyxia can reduce the incidence of neonatal pneumothorax.

Objective To investigate the effects of dedicator of cytokinesis 1 (Dock180) knockout on proliferation and apoptosis in rat derived H9C2 cardiomyocytes and their mechanisms.Methods A single guide RNA (sgRNA) targeting rat Dock180 gene was designed and constructed using CRISPR/Cas9 system.A plasmid contained above sgRNA was packaged into lentivirus and selected to knockout Dock180 in the cardiomyocytes.A single clone of cardiomyocyte with Dock180 knockout was established.Cardiomyocytes were divided into negative lentivirus group (Cas9, A group), Dock180 knockout group (B group), Cas9 lentivirus hypoxia group (C group), Dock180 knockout hypoxia group (D group).The expression of Dock180 mRNA was examined by RT-PCR, and relevant proteins were detected by Western blot.The cell proliferation rate of the cardiomyocytes was determined by MTT, and the apoptotic rate was measured by flow cytometry.Results Dock180 mRNA and protein were absent in B andD groups.Compared with A and C groups, p-ERK1/2 and Bcl-2 protein expression and cell proliferation rate were lower in B and D groups respectively (P<0.01), while Bax protein expression and cell apoptosis rate were higher in B and D groups respectively (P<0.05, P<0.01);Compared with A group, Dock180 mRNA and protein, p-ERK1/2 and Bcl-2 proteins and cell proliferation rate were reduced, while Bax protein and cell apoptosis rate were increased in C group(P<0.05,P<0.01).Compared with B group, p-ERK1/2 and Bcl-2 proteins and cell proliferation rate were decreased, while Bax protein and cell apoptosis rate were increased in D group(P<0.05,P<0.01).Conclusions Dock180 knockout with CRISPR/Cas9 can inhibit proliferation and promote apoptosis via p-ERK1/2, Bcl-2 and Bax in H9C2 cardiomyocytes.

Objective To assess on the effect of the different catheterization on patients with oral poisoning gastric lavage systematically and objectively. Methods A computerized search of PubMed, the Cochrane Library, EMBASE, Springer Link, Science Direct,China Biology Medicine (CBM),China National Knowledge Internet(CNKI), Wanfang Data and VIP database was performed for relevant randomized controlled trials (RCTs) which investigated the effects of the oral intubation gastric lavage on patients with oral poisoning relative to nasogastric lavage, retrieval to January 2016, and back into the study of references. According to include and exclude standard to screening literature, literature which met inclusion criteria was selected for quality evaluation and data extraction. Meta-analysis and trial sequential analysis were performed by using Rev-Man 5.3 and TSA soft-ware to estimate the required information size (RIS). Results 13 studies incorporated into Meta-analysis including a total o 1 296 patients. Meta-analysis results showed that the oral intubation gastric lavage group was better than nasogastric lavage in shortening the time of intubation [MD=-9.05, 95% CI(-12.86--5.23), P=0.00], improving the rate of intubation for the first time [MD=1.36, 95% CI (1.14-1.62), P =0.00], mucosal bleeding complication [MD=0.11, 95% CI (0.04-0.64), P=0.010], nausea and vomiting [MD=0.60, 95%CI (0.37-0.98), P=0.04], kinking [MD=0.14, 95% CI (0.02-0.80), P=0.03], reflex cardiac arrest [MD=0.24, 95% CI (0.08-0.71), P=0.01] and asphyxia [MD=0.45, 95% CI (0.26-0.80), P=0.007], the difference were statistically significant. But no significant difference existed in gastric tube fall off. Conclusions The oral intubation gastric lavage could shorten intubation time of patients, improve the first time intubation rate and reduce certain complications. It suggests that the oral intubation be extensively applied to care patients with oral poisoning.
