Objective To explore effective nursing intervention through clinical analysis of middle ear function of children with obstructive sleep apnea hypopnea syndrome(OSAHS).Methods Tympanogram was obtained from both pre-operation and post-operation in 413 OSAHS cases(the OSAHS group).Audiogram was conducted if the tympanogram was abnormal.There were 279 cases of normal children in the control group.The incidence of middle ear function loss of two groups were compared.Results 288 cases(328 ears) had some degree of middle ear dysfunction,accounting for 69.73％.69 cases had some degree of hearing loss,accounting for 16.71％.The incidences of middle ear dysfunction and degree of hearing loss in the OSAHS group were higher than 7.53％ and 1.43％ of the control group.The hearing ability was gained after operation in both groups.Conclusions The incidence of middle ear dysfunction is higher in children with obstructive sleep apnea hypopnea syndrome.But the bad influence alleviated with age.Therefore,early detection,timely treatment and effective nursing can achieve good effect.

Objective To explore the impact of executive function intervention on the executive functioning of elderly patients with cerebral infarction,and to seek the best way to improve executive function in such patients.Methods Eighty elderly patients with cerebral infarction were randomly divided into an intervention group and a control group.A series of executive function interventions were administered to those in the intervention group with no intervention in the control group.The two groups were given the same conventional medication.The Behavioral Assessment of the Dysexecutive Syndrome (BADS) was taken before the intervention,then 3 months and 6 months after recruitment.Results In the intervention group the average score and the total standard score had increased significantly after 3 months except for the action program test and the modified six elements test.Both indicators were still significantly increased from the baseline afar 6 months except for the modified six elements test.The average score and the total standard score had increased significantly between 3 months and 6 months except on the key search test.Both the time determination test and the total standard score had statistically significant average differences.The control group showed no significant differences.After 3 months,the average scores and the total test standard scores in the intervention group were signifieantiy higher than those in control group except on the action program test.The rules conversion card test,the time determination test and the total standard score difference all showed statistically significant differences between the groups.After 6 months the intervention group's scores remained significantly higher than those of the control group except on the action program test.Conclusions Executive function interventions are effective in delaying the progress and improving the prognosis of executive dysfunction in elderly patients with cerebral infarction,and the therapy has persistent effects.

· As a member of the stem cells family, mesenchymal stem cells ( MSCs ) have been proved to be effective on the repair of tissue injury. Although the specific mechanism is still unclear, MSCs do have a promising future in retinal disease therapy.The results of the current research are diverse.We still have an urgent and long way to explore the details of MSCs.So it’s significant for further understanding of MSCs to analyze the possible mechanism and influencing factors.

Objective To observe the clinical effects of anterior plates with titanium mesh and bone graft (auto and allo) in treatment of cervical spine fractures. Methods 42 cases of fractures of cervical spine treated with anterior plates with titanium mesh. Results The bone graft (auto and allo) were followed up for 4 to 28 months (mean 17 months). The preoperative and postoperative nerve functions were evaluated according to JOA criteria. The cervical curvatures, sink or shift of the mesh and bone fusion were evaluated by X rays. There were no significant complications during perioperative periods. The functions of spinal cord were improved, the cervical curvatures were restored, and no sinking or shifting of the mesh was observed. There was also no loosening of plate or screw. The fusion began 3.5 months postoperatively, and a good fusion could be observed 1 year postoperatively. Conclusion By application of anterior plates with titanium mesh and bone graft (auto and allo) in treatment of cervical spine fractures, the cervical curvature and stability can be restored, the iliac lesion and long operation duration caused by the harvest from ilium can be avoided, better fusion and quicker recovery can be obtained.

Objective To investigate the clinical characteristics of septicemia in type 2 diabetes mellitus,to enhance prevention level and decrease death rate.Methods A retrospective study was carried out,the data were collected from 58 cases of type 2 diabetes mellitus complicated by septicemia in our hospital in the past 13 years.Results The pathogenic invasive pathways included:19 cases of urinary tract,17 cases of respiratory tract,7 cases of intravenous catheter detain,7 cases of biliary tract,1 case of skin breakage,and 7 cases of unclear origin.Twenty-three of 58 cases were from nosoeomial infection (39.7%),among which 10 cases of urethral detain,7 cases of intravenous catheter detain,and 6 cases of respiratory tract infection.Pathogenic distribution was as following:24 cases of klehsiella pneumoniae,16 cases of escherichia coli,10 cases of staph aureus,2 cases of staphylococcus cohnii cohnii,2 cases of staphylococcus epidermidis,2 cases of pseudomonas putida,2 cases of candida glabrata.Among the 24 cases of llehsiella pneumoniae,12 cases showed migrating hepatapostema (50.0%),and 15 showed pneumatosis phenomenon in the intrahepatie bile (62.5%).Two cases originated from fungal septicemia.Among 56 cases under antibacterial therapy 15 cases developed fungal septicemia (26.8%).Fifty-eight cases were treated with insulin for forcing down serum glucose,56 cases of bacterial septicemia were treated with the third generation cephalosporins and fluoroquinolones.Two cases of pseudomonas putida septicemia were treated with intravenous injection of fluconazole.Seven cases died (12.1%).Conclusions Gram-negative bacilli were the major pathogens of septicemia in type 2 diabetes mellitus.Migrating hepatapostema and pneumatosis phenomenon in the intrahepatic bile often showed klebsiella pneumoniae septicemia.The important risk factors for septicemia were intravenous catheter detain and urethral detain.Therefore,strictly aseptic operation and removing vessel detain in time is very important.It is key points to make an early diagnosis,have a strong antibiosis therapy and treat the migrating pathogenic focus.And it is important to intensify serum glucose monitoring and strengthen supportive treatment.

Objective To observe the effects of White Mange Mixture on the content of VEGF and the genetic and protein expressions of VEGFR-2 of HaCaT cells;To explore its mechanism. Methods HaCaT cells were cultured in vitro to establish psoriasis experimental model. SD rats were randomly divided into the blank serum group, white mange mixture of low-, medium- and high- dose groups and acitretin group, meanwhile to set up blank control group. Cultured HaCaT cells model were intervened with different medicine serum. ELISA was applied to detect the content of VEGF. RT-PCR and Western blot were used to detect the genetic and protein expressions of VEGFR-2.Results Compared with the blank control group, White Mange Mixture of low-, medium- and high-dose groups interventing HaCaT cells could obviously inhibit the secretion of VEGF and decrease the genetic and protein expression of VEGFR-2 in a dose-dependent manner. Conclusion White Mange Mixture plays a role in the treatment of psoriasis possibly through inhibiting the content of VEGF and decreasing the genetic and protein expressions of VEGFR-2.

Bone marrow transplantation was considered effective treatment for leukemias and other haematological diseases. Acute graft v-host disease (GVHD) is a major complication of allogeneic bone marrow transplantation. The T lymphocytes were specially depleted by anti-CD5, CD2, CD8, CD27 monoclonal antibody-ricin immunotoxins. Inhibition of the protein synthesis and T-cell functions in the target cells was observed in vitro. At 10 9mol / L of the immunotoxin, 3 logs (99.9%) of target cells were killed, but no cytotoxicity on nontarget cells. At the same concentration, the anti T cell immunotoxin had no any influence on the proliferating rate of CFU-GM and BFU E. None of the ten patients who received T cell depleted bone marrow developed grade III or IV acute GVHD.

Objective To study the expression of HOXA10 gene in the endometrium of normal fertile women and patients with unexplained infertility during different phases of menstrual cycle. Methods Endometrium samples were obtained by curettage in 52 normal fertile women and 38 patients with unexplained infertility during different phases of menstrual cycle, HOXA10 mRNA expression were detected by in situ hybridization and reverse polymerase chain reaction (RT-PCR). Results (1) HOXA10 mRNA were detected in the glandular and stromal cells of endometrium of fertile women during the menstrual cycle. By in situ hybridization (positive unite, PU), HOXA10 mRNA levels were significantly higher in the mid-secretory phase [glandular cells (G) 5.69?0.57,stromal cells (S) 7.48?0.67] and late-secretory phase(G 5.99?0.40,S 7.98?1.08) than those in late proliferative phase (G 3.35?0.20,S 3.20?0.37) and early secretory phase (G 3.07?0.26,S 3.18?0.27)(P

Cerebral small vessel disease is a common cerebrovascular disease in clinical practice.It is mainly characterized by insidious onset and slow development.Some may have acute attack.The imaging features of cerebral small vessel disease mainly include cerebral white matter lesions,lacunar infarction,cerebral microbleed and cerebral perivascular space expansion.It is closely associated with cognitive impairment.All imaging findings can occur simultaneously and interact,further aggravate cognitive impairment,and ultimately lead to dementia.Therefore,the influence of cerebral small vessel disease on the quality of life and social function of the patients cannot be ignored.
