Objective To investigate the effective of FGF-23(R176Q)overexpression of adult mouse mandible formation and mineralization.Methods CT scanning,serological examination,HE staining,immunohistochemical staining and RT-PCR analysis were used to compared mandible of FGF-23(R176Q)transgenic mice(TG group)and wild type mice(WT group),serum calcium and phosphorus concentrations mandibule formation and mineralization were analysised.Results Serum calcium,phosphorus and 1, 25(OH)2 D3 concentrations in WT group were significantly higher than that in TG group,the difference was statistically significant (P <0.05);the Ob.s/B.Pm TG group was lower than that of WT group,the difference was statistically significant(P <0.05);the positive percentage of Biglycan in TG group was higher than that in WT group,the difference was statistically significant(P <0.05);the OCN and type I collagen mRNA levels in the WT group were significantly higher than that in TG group,the difference were statistically significant(P <0.05).Conclusion FGF-23(R176Q)overexpression can inhibit the formation of mandible,reduce the formation of mineralized,and reduce the development of the mandible.

ObjectiveTo investigate the role of T-type calcium channel in the spinal neurotoxicity of intrathecal (IT) lidocaine in rats.MethodsForty-eight adult male SD rats in which IT catheter was successfully implanted,weighing 230-270 g,were randomly divided into 4 groups ( n =12 each):dimethyl sulfoxide (DMSO)group (group D),lidocaine group (group L),mibefradil + lidocaine group (group M),normal saline + lidocaine group (group N).Another 12 rats served as control group (group C).DMSO and 10% lidocaine 20μl were injected intrathecally in groups D and L respectively.After mibefradil 200 μg/10μl and normal saline 10 μl were injected intrathecally in groups M and N respectively,10% lidocaine 20 μl was injected intrathecally in the two groups.The mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were measured before IT injection and at 2,4,8 and 12 h and 1,2,3,4 and 5 d after IT injection (T0-9).Four rats were sacrificed at T6 in each group and their lumbar enlargements were removed for microscopic examination.ResultsCompared with group C,no significant change in MWT and TWL was found at each time point in group D,MWT was significantly increased at T1-8 and TWL was significantly prolonged at T1-7 in groups L and N,and MWT was significantly increased at T1-6 and TWL was significantly prolonged at T1-6 in group M ( P < 0.05 ).Compared with groups L and N,MWT was significantly decreased at T1-4 and TWL was significantly shortened at T1-4 in group M ( P < 0.05).Pathological injury was significantly reduced in group M as compared with groups L and N.ConclusionT-type calcium channel is involved in the spinal neurotoxicity of IT lidocaine in rats.

Objective To discuss the role of leukocyte activation and inflammatory processes in the disease of chronic venous insufficiency(CVI).Methods The relevant literatures about the role of leukocyte activation and in- flammatory reaction in CVI were reviewed.Results The role of inflammatory reaction in occurrence and develop- ment of venous diseases has been studied a lot in recent years.It was found that the leukocyte activation and inflam- matory reaction are involved in the structural remodeling of venous valves and walls,leading to valvular incompe- tence and formation of varicose veins.Conclusion Leukocyte activation and inflammatory processes take important roles in the occurrence and progression of CVI.

Objective:To describe health service use and trend of treatment and rehabilitation rates among people with psychiatric disability from 2007 to 2013.Methods:Data collected by the 2006 Second China National Sample Survey and the 2007-2013 National Disability Monitoring Survey were utilized and analyzed.The 2006 National Sample Survey on Disabilities investigated 2 526 145 non-institutionalized representative civilians in 734 counties across mainland China.Psychiatric disability was diagnosed by clinical psychiatrists according to ICD-10 and WHO DAS Ⅱ criteria.The 2007 to 2013 National Disability Monitoring Survey selected 1 to 2 study sites among each of the 734 study counties that had been investigated by the Second China National Sample Survey.Information on living conditions,health service use,education and employment were recorded.Results:The data showed that treatment and rehabilitation rates for people with psychiatric disability had largely increased from 2007 to 2013 among adults aged 18 years or older,with the treatment and rehabilitation rates from 49.52% and 21.8% to 66.9% and 58.7% respectively,and the rates among those with 17 years or younger from 23.5% to 43.9%.However,with regard to the effect of the treatment and rehabilitation services,a much larger proportion of people with psychiatric disability reported that the effect was soso instead of good or very good.In addition,among those who received rehabilitation service,most received day care or psychotherapy service,only less than 8% participated work therapy,farming therapy or working skill trainings.Conclusion:The results suggest treatment and rehabilitation rates among people with psychiatric disability are largely increased from 2007 to 2013,while the quality of the service needs further attention.

Objective To explore the effectiveness of long-acting antibacterial material that was used as an intervention in oral care cavity nursing in patients with endotracheal intubation and mechanical ventilation. Methods Patients admitted to Xuzhou Medical College Hospital neurosurgery intensive care unit between 1st December 2013 and 31st August 2014 requiring intubation and mechanical ventilation were enrolled into the study. There were 100 cases randomly selected and were assigned into control group and experimental group by random number table. Each contained 50 cases. Control group used saline for oral care by brushing and irrigation;experimental group used antimicrobial material oral spray in oral care on the top of the method used in control group. The mouth odor, mouth infection rate and ventilator-associated pneumonia (VAP) rate were used to determine. Results About oral odor, mouth infection rate, and VAP rate, the difference of incidences between experimental group and the control group was significant (χ2=4.504-13.728, P <0.05). Conclusions Antimicrobial material can effectively improve oral health in intubated and mechanical ventilated patients. It slows oral acidic environment change, reduces oral infections early onset VAP incidence. And it is worth promoting its use.

Objective To investigate the value of blood culture result in guiding clinical rational use of drugs in clinic.Methods The medical records of 100 children patients with blood culture positive in the four departments of our hospital were retrospectively analyzed.Results The empirical treatment accounted for 98%,the goodness of fit in the medication before culture with the appropriate antibacterial drugs according to final detected bacteria was only 51.6%;after issuing the level 1 report,the adding and substituting drugs in adjusting the antibacterial drugs accounted for about 20% each,60% of antibacterial drugs were not adjusted;after issuing the level 2 report,about 5% of children patients added the antibacterial drugs,the proportion for replacing antibacterial drugs reached 32%,meanwhile the proportion for reducing accounted for 3%;after issuing the level 3 report,the consistency of antibacterial drugs use with the final drug susceptibility test results reached 83%,the inconsistency was only about 5%.Conclusion Clinical pediatric doctors in this hospital still heavily rely on the results of blood culture 3 levels reports,executing antibacterial agents from the experience treatment to the target treatment is also very active.
