0.05).[Conclusion] Lumbar accessory processes could be displayed clearly by MSCT volume reconstruction,which offers great help in the clinical practice.

Objective To investigate the FDG PET-CT image characteristics of bone metastases from lung cancer and the clinical value of 18F-fluorodeoxyglucose(FDG)PET-CT for diagnosis to bone metastases from lung cancer.Methods 32 cases of bone metastasis from lung cancer examined by FDG PET-CT had been studied.All of them were proved by pathology after operation or biopsy.Their FDG PET-CT diagnosis were analyzed by comparing with CT diagnosis. Results All of 115 lesions of 32 cases showed intense uptake of 18F-FDG. SUV mean was 7.47±3.48. 115 lesions located in 42 pieces of bones. Most importantly.16 lesions of occult bone metastases of 12 cases were found.The most related bone were ribs(26/115,22.61%),thoracic vertebral(21/115,18.26%),iliac bone(18/115,15.65%)and lumbar vertebral(16/115,13.91%).96 lesions(83.48%)showed lytic type on CT images,1 lesion(0.87%)showed sclerotic type,and 2 lesions(1.74%)showed mixture type.Conclusion The FDG PET-CT can early detect bone metastases from lung cancer.show their exact location,and have superiority in the screen of bone metastases from lung cancer.

Objective To examine the barbiturate infusion for intractable intracranial hypertension and its effect on brain tissue oxygen ( PbtO2 ). Method 60 patients with intractable intracranial hypertension were divided into tow groups, experimental group and control group. PbtO2 and intracranial pressure (ICP) were continuous monitored. Follow-up was more than 3 months and the prognosis was compared between two groups. Results When pentobarbital administration began, the mean PbtO2 [ 72 h: (26. 7 ±6. 7)mmHg] at 24h, 48h and 72h in experimental group were significantly higher than that of control group [ 72 h: ( 21. 1 ± 7. 2) mmHg ] ( P < 0. 05 ). The mean ICP [ 5 d: (2. 48 ± 1.11 ) kPa ] in the third and fifth day of experimental group were lower than that of control group [ 5 d: (3. 12 ± 1.09 ) kPa ]. Prognosis of pentobarbital group was better than control group( P < 0. 05 ). Conclusions Pentobarbital can effectively reduce intracranial pressure in patients with refractory intracranial hypertension and improve brain tissue oxygen. PbtO2 is an ideal monitoring marker, and it can predict prognosis to a certain extent.

Objective To investigate the relationship between a mutation in the platelet-activating factor (PAF) acetylhydrolase gene (Arg92→His) and psoriasis. Methods Genomic DNA was analyzed in 47 patients with psoriasis and 52 healthy controls via polymerase chain reaction and restriction fragment length polymorphism. Results The frequency of the mutation in the PAF acetylhydrolase gene (Arg92→His) was significantly higher in patients with psoriasis than that in the controls (P

Objective To explore the imaging findings and diagnostic values of X-ray, CT, MR,and ultrasonography in traumatic knee joints hemarthrosis and lipohemarthrosis. Methods Traumatic knee joints hemarthrosis (12 knees) and lipohemarthrosis (18 knees) proved by operation (27 knees) or puncturation (3 knees) were included in the study. Horizontal-beam plain radiographs (16 knees), CT (30 knees), MRI (30 knees) and ultrasonography (24 knees) in supine position were investigated. Results (1)supine position horizontal-beam plain radiographs: Fat-liquid layer was found in 8 cases of lipohemarthrosis. Dense supragenual bursa was found in 1 case of lipohemarthrosis and 7 cases of hemarthrosis. Fracture (13 knees) was diagnosed correctly. (2) CT findings: double fluid-fluid layer was found in 11 of all 18 cases, and single fluid-fluid layer was found in 7 of 11 cases of lipohemarthrosis. Single fluid-fluid layer was found in 3 of 12 cases of hemarthrosis. Isodensity was detected in 9 cases, and high-density blood clot was found in 4 cases. Fracture (30 knees) was diagnosed correctly. (3) MRI findings: in 12 of 18 cases of lipohemarthrosis, double fluid-fluid layer was shown including supernatant layer as short T1, long T2signal and low signal after fat-suppression, middle layer as long T1, long T2 signal and high signal after fat-suppression, and dependent layer as iso-T1, iso-T2 and slight high signal after fat-suppression. Single fluid-fluid layer was seen in 6 cases, only had aforementioned upper and under layer.Only aforementioned supernatant layer and dependent layer were seen in 12 cases of hemarthrosis. 4 cases showed entire blood clot in fluid, T1WI showed middle signal or center iso-signal accompanied with peripheral high signal ring, and fat-suppression imaging showed high signal. T2WI and fat-suppressionimaging showed middling or high signal accompanied with peripheral low signal ring. Fracture (30 knees) was diagnosed correctly. (4) Ultrasound findings: In 10 of 14 cases of lipohemarthrosis, double fluid-fluid level was shown, supernatant layer as equal echo, middle layer as echoless, and dependent layer as cloudy echo. Four cases with single fluid-fluid level only showed aforementioned upper and under layer. Three of 10 cases of hemarthrosis showed single fluid-fluid level, only showing aforementioned upper and under layer,and 7 cases showed cloudy echo and float. In 3 cases the fluid blood clot showed irregular shape low-equal echo bolus. No fracture hne was found. Conclusions CT can clearly detect fracture line, hemarthrosis and lipohemarthresis, and can substitute plain radiography. MRI is the best way to diagnose hemarthresis and lipohemarthrosis. Ultrasonography can be used in diagnosing hemarthresis and lipohemarthrosis but not helpful in the diagnosis of fracture.

Objective To observe changes in relative pituitary hormones after severe traumatic brain injury (STBI) in children and to investigate the short-and long-term effects of mild hypothermia on pituitary function.Methods Included for this study were 81 children who had been admitted to the Brain Hospital of Liaocheng People's Hospital from June 2011 to January 2015 for STBI and abnormal secretion of pituitary-related hormones.They were divided by the wishes of patients and their families into 2 groups,subjected to mild hypothermia treatment (n=42) or conventional treatment (n=41).The levels were examined of growth hormone (GH),prolactin (PRL),adrenocorticotropic hormone (ACTH),free triiodothyronine (FT3),free thyroxine (FT4) and thyroid stimulating hormone (TSH) for both groups unpon admission and in the moming of 1,3,5,7 and 14 days after injury.At 6 months after injury the patients were followed up for Glasgow Outcome Score (GOS) and levels of pituitary-related hormones.Results Of the 83 patients,disturbance of one single hormone was found in 31 (30.10％) and disturbance of 2 or more hormones in 52 (50.48％).The top 3 hormones disturbed were PRL,ACTH and GH.On days 3,5 and 7 after injury,the levels of PRL and ACTH in the mild hypothermia treatment group were significantly lower than in the conventional treatment group (P＜0.05).On day 3 after injury,the level of FT3 in the mild hypothermia treatment group was significantly lower than in the conventional treatment group (P＜0.05).At 6 months after injury,the GOS score for the conventional treatment group was 3.04±0.38,significantly lower than that for the mild hypothermia treatment group (4.56±0.62) (P＜0.05).The incidence of hypopituitarism in the hypothermia treatment group (16.67％) was significantly lower than in the conventional treatment group (46.88％) (P＜0.05).Conclusions Incidence of pituitary dysfunction is high in children following severe traumatic brain injury.Mild hypothermia treatment can effectively alleviate early-stage parasecretion of pituitary hormones,and decrease the incidence of later pituitary dysfunction.
