Objective To study the perioperative nursing methods in patients with OSAHS and type 2 diabetes mellitus.Methods From March 2009 to December 2010,a total of 46 patients with OSAHS and type 2 diabetes mellitus were randomly divided into the control group and the experimental group with 23 cases in each group.Conventional care was given to the control group,while the experimental group received systematic,phased and individualized nursing.The sleep quality before and after the operation was compared.The oropharynx wound healing and possible complications,pain were observed after operation.Results In the control group,there was one patient with bleeding during operation,one patient happened blood lost after operation and 2 patients had postoperative infection.The hyperglycemia was found in 3 patients and hypoglycemia occurred in 2 patients.But in the experimental group,all of the patients did not suffer complication.The scores of sleep quality on the day before surgery were significantly higher than those scores on admission,and the scores on discharge from hospital were significantly lower than those scores on admission.There were statistical differences.The scores of the experimental group were significantly improved compared to those of the control group.The score of pain was the highest at the day of surgery,and then gradually decreased.The score of pain of the experimental group was significantly lower than that of the control group,and the difference was statistically significant.Conclusions This comprehensive nursing method during operation period for patients with OSAHS and type 2 diabetes mellitus not only can reduce risk of postoperative complication,but also can improve operation efficacy,quality of nursing and life quality of patients as well as can speed recovery.It approved that this standardized,systematic nursing method during the whole period is practical and effective in OSAHS and type 2 diabetes mellitus treatment and care.

The hexane extract from marine actinomycetes 124092 showed potent inhibition on B16 cell line by MTT assay. The hexane extract was fractionationed on silica gel column by vacuum liquid chromatography to afford 6 fractions(Fr1~Fr6), and Fr6 showed cytotoxic activity. To determine the bioacitve components of hexane extract, Fr6 was analyzed by GC/MS. The main components were identified as palmitic acid (11.76%), oleic acid (12.16%), linoleic acid (14.77%), and lactobacillic acid (61.31%). It have been reported that palmitic acid, oleic acid, and linoleic acid possess cytotoxic activity on rat ascites tumor cells and linoleic acid have suppressive effect on human lung adenocarcinoma cells.

Objective To analyze the X-ray,CT and MRI findings of synovial tuberculosis,and to evaluate the role of MRI in diagnosing synovial tuberculosis.Methods Fourteen eases of synovial tuberculosis comfirmed by operation and pathology were retrospectively analyzed and summarized. All patients were examined by MRI and X-ray,and CT scans were performed in 3 cases. Results X-ray showed joint swelling(8 cases),articular space narrowing(7 cases),marginal joint erosions(4 cases), and periarticular osteoporosis(9 cases).The joint swelling was detected on CT in all 3 cases,and bony erosion and speckled sequestra were seen in 2 cases.MRI in all of patients showed joint swelling and synovial proliferation in different drgees,demonstrated as heterogeneously low signal on T_1 WI and slight high signal(7 cases)and obvious high signal(6 cases)on T_2WI,and diffuse synovial proliferation was demonstrated as massive and nodular signal in 8 cases.Joint effusion was present in 7 cases as low signal on T_1WI and high signal on T_2 WI.Osseous erosion lesions were seen in 7 cases,and intra-artieular cartilage thinned,partly or mostly disappeared in 11 cases.Periarticular bone marrow edema was found in 7 cases. Conclusion MRI was superior to X-ray and CT in the diagnosis and differential diagnosis of synovial tuberculosis.

Objective To examine how stroke affects muscle coordination and whether muscle function will be improved after rehabilitation.Methods Ten stroke patients with mild hemiparesis and six age-and sex-matched controls were investigated at baseline.Velocity-encoded phase-contrast magnetic resonance imaging (VE-PC MRI) and surface eleetromyography (sEMG) were performed to evaluate muscle coordination of thigh muscles during knee extension and flexion and the effect of rehabilitation. Results Using VE-PC MRI,we found that the peak velocity of rectus femoris was lower in the affected limb (P

OBJECTIVETo evaluate the clinical characteristics and short-term outcomes of neonatal asymmetric crying facies (ACF), in order to improve recognition of the disease.

METHODSThe clinical data of 11 infants with ACF between January 2010 and February 2012 were retrospectively studied. Physical and neurological development were followed up at correct gestational age 44 weeks and 3 months.

RESULTSOf the 11 infants with ACF, 4 had ipsilateral ear malformation, 2 had congenital heart disease and 1 had syndactyly and polydactyly. Of the 11 infants, 8 were male and 3 were female. Eight infants presented with lesions on the left side and 3 presented with lesions on the right. The fathers were aged over 35 in 8 cases and the mothers were over 30 in 7 cases. Eight mothers had a history of at least 3 pregnancies and 2 infants were born to mothers with diabetes mellitus. Physical index was below P10 in 1 case and 2 cases showed a low NBNA score and mild abnormal GMs (poor repertoire PR) during the writhing period at correct gestational age 44 weeks. Physical index was between P10-P90 and GM assessment during the fidgety period showed normal movements in all infants at correct gestational age 3 months, but they still had ACF.

CONCLUSIONSACF is associated with a high rate of other congenital malformations. The short-term outcomes of ACF infants are satisfactory, but long-term follow-up and interdisciplinary cooperation are necessary to improve prognosis.

Objective To explore the diagnosis and therapy experience of vascular ring combined with tracheal compression in infants and neonates.Methods Sixteen cases(including 7 boys and 9 girls,aged 1 day to 12 months)with vascular ring combined with tracheal compression hospitalized in Guangdong General Hospital from Jun.2004 to Dec.2009 were enrolled.In these 16 children,13 cases had congenital heart malformations.All children underwent X-ray,echocardiography and spiral computed tomography examination.Nine cases received bronchoscopy study.Fifteen cases performed surgical division of vascular ring with cardiopulmonary bypass and 1 case underwent vascular ring division and tracheoplasty.Eleven cases received management of congenital heart defect simultaneously.Results Vascular ring anomalies included pulmonary artery sling in 5 children,right aortic arch-left ligmentum/aberrant left subclavian artery in 8 cases,double aortic arch in 1 case,innominate artery compression in 1 case,and pulmonary sling combined with right aortic arch-aberrant left subclavian artery in 1 case.There were 2 ring-sling complex cases in this study.The diagnosis of vascular ring were correctly made by echocardiography in 7 children and made by spiral computed tomography in all 16 cases.Two cases combined with tracheal ring died.In the follow-up study of 11 cases,5 cases were still vulnerable to wheezing.Conclusions The common presentation of tracheal compression in infants and neonates associated with vascular ring are tachypea,stridor,and dyspnea.Multi-slices spiral computed tomography is an important imaging modality.Surgical divisions of vascular ring are safe procedure in most cases and tracheal compression can be relieved by this operation.In patients with severe tracheal stenosis,tracheoplasty should be recommended.

OBJECTIVETo explore the association between chorioamnionitis and brain injury in preterm infants.

METHODSA total of 88 preterm infants (28-34 weeks), who were born between June 2008 and June 2011, were divided into a case group (n=41) and a control group (n=47) according to whether or not they had chorioamnionitis. All the infants were examined by brain ultrasonography periodically after birth and underwent brain diffusion weighted imaging (DWI) between 3 and 7 days after birth. The two groups were compared in terms of the incidence of periventricular leukomalacia (PVL) and periventricular and intraventricular hemorrhage (PVH-IVH) by brain magnetic resonance imaging (MRI) at the corrected gestational age of 40 weeks.

RESULTSThere was statistical significance in the incidence of PVL between the case and the control groups (32% vs 6%; P<0.05), but no significant difference in the incidence of PVH-IVH between the two groups (27% vs 23%; P>0.05).

CONCLUSIONSChorioamnionitis is associated with brain injury in preterm infants, increasing the incidence of PVL but having little influence over the incidence of PVH-IVH.

Two plasmid constructs, pcE2 and pcE3, containing 3' fragment of open reading frame 2 (ORF2,1163 bp) of hepatitis E virus (HEV) and full-length ORF3 (369 bp), were injected into bilateral tibialis of Swiss mice respectively，for three times (0, 2nd and 4th weeks) and observed the HEV IgG by ELISA. HEV IgG was induced after the injection of pcE2 or pcE3 or both, and the percentage of seraconversion was 100% after two weeks of the third injection. Compared with injection of either construct, the antibody titers were higher in the group with combined injection of two constructs.

OBJECTIVEThe application and therapeutic effect of hyperbaric oxygen (HBO) in hypoxic-ischemic brain damage (HIBD) remains controversial. Previous studies have focused on the early pathological and biochemical outcomes and there is a lack of long-term functional evaluation. This study was designed to evaluate the long-term pathological and behavioral changes of early HBO therapy on neonatal rats with HIBD.

METHODSPostnatal 7 days (PD7) rat pups were randomly assigned into Control (n=18), HIBD (n=17) and HBO treatment groups (n=17). HIBD was induced by ligating the left common carotid, followed by 2 hrs hypoxia exposure in the HIBD and HBO treatment groups. The Control group was sham-operated and was not subjected to hypoxia exposure. The HBO therapy with 2 atmosphere absolutes began 0.5-1 hr after HIBD in the HIBD treatment group, once daily for 2 days. The spatial learning and memory ability were evaluated by the Morris water maze test at PD37 to PD41. The morphological and histological changes of the brain, including brain weight, survival neurons, AchE positive unit and NOS positive neurons in hippocampal CA1 region, were detected at PD42.

RESULTSThe rats in the HIBD group displayed significant morphological and histological deficits, as well as severe spatial learning and memory disability. In the Morris water maze test, the mean escape latency were longer (56.35 +/- 22.37 s vs 23.07 +/- 16.28 s; P < 0.05) and the probe time and probe length were shorter in the HIBD group (29.29 +/- 6.06 s vs 51.21 +/- 4.59 s and 548 +/- 92 cm vs 989 +/- 101 cm; both P < 0.05) compared with the Control group. The left brain weight in the HIBD group was lighter than that in the Control group (0.601 +/- 0.59 g vs 0.984 +/- 0.18 g; P < 0.05). The survival neurons in the hippocampal CA1 region were less (100 +/- 27/mm vs 183 +/- 8/mm; P < 0.05), as well as the AchE-positive unit and NOS-positive neurons (18.50 +/- 2.24% vs 27.50 +/- 2.18% and 19.25 +/- 4.33 vs 33.75 +/- 5.57 respectively; P < 0.05) after HIBD. Early HBO treatment improved the abilities of spatial learning and alleviated the morphological and histological damage. The mean escape latency (39.17 +/- 21.20 s) was shortened, the probe time (36.84 +/- 4.36 s) and the probe length (686 +/- 76 cm) were longer, and the brain weight (0.768 +/- 0.85 g), the survival neurons (133 +/- 25/mm) and the AchE-positive unit (21.94 +/- 2.73%) increased significantly compared with those of the HIBD group (P < 0.05).

CONCLUSIONSEarly HBO treatment resulted in a protective effect against HIBD-induced long-term brain morphological and histological deficits and spatial learning and memory disability.
