OBJECTIVETo study the MRI features of proximal femur bone marrow edema syndrome for further improve the understanding of the disease.

METHODSMRI imaging of 10 patients with proximal femur bone marrow edema syndrome was retrospectively reviewed,including 6 males and 4 females with an average age of 41.5 years old ranging from 36 to 57. The courses of diseases ranged from 1 week to 3 months. Among them, 9 cases had clinical manifestations of sudden hip pain, 7 cases had limited ability of walking and hip movement;all patients had no obvious injury history, non of the female patients was pregnant. All patients were followed up from 3 to 12 months, the following-up were topped after MRI when the symptoms disappeared for 3 months.

RESULTSThe MRI demonstrated diffuse bone marrow edema involving the femoral head, neck and the inter-trochanteric region, 13 hips of 10 patients with bone marrow edema included 6 cases in grade 1, 5 cases in grade 2,2 cases in grade 3; 9 hips with hip hydrarthrosis included 6 hips in grade I ,1 hip in grade II, 2 hips in grade III. After treatment for 3 to 12 months the hip symptoms of the patients disappeared and MRI images were normal.

CONCLUSIONMRI is useful in defining the location and extent of proximal femur bone marrow edema syndrome.

Hypertension in children is defined as systolic blood pressure and/ or diastolic blood pressure≥95th percentile for age,gender and height,on at least 3 occasions. Persistent hypertension despite non - pharmacologic measures should be treated with anti - hypertensive drugs. Angiotensin - converting enzyme inhibitors,angiotensin receptor blockers,calcium channel blockers,β - blockers and diuretics are safe,effective,and well tolerated in children. This article describes the selection and clinical application of anti - hypertensive drugs in children.

Objective To discuss the clinical observation of Montmorillonite combined with Compound Eosinophil-Lactobacillus Tablet in the treatment of pneumonia infants of antibiotic associated diarrhea (AAD).Methods Eighty pneumonia infants with antibiotic associated diarrhea were selected,they were divided into two groups according to the random number table method.The observation group (41 cases) was given Montmorillonite.The control group (39 cases) was given Montmorillonite and Compound Eosinophil-Lactobacillus.The efficacy of Montmorillonite combined with compound Eosinophil-Lactobacillus Tablet in the treatment of pneumonia infants of antibiotic associated diarrhea was evaluated by efficacy,clinical symptom,immune function changes and adverse reactions during the treatment period.Results After treatment,the effective rate of observation group was higher than that of the control group (P ＜ 0.05).After treatment,the fever time,correcting dehydration time,and antidiarrheal time of observation group was shorter than that of the control group (P ＜ 0.05).After treatment,the serum IgG,IgA,and T lymphocyte subsets of CD3+,CD4+ levels were significantly increased in the observation group (P ＜ 0.05).There was no statistical significance on CD8+ before and after treatment.In contrast,there were no statistical significance on the serum immunoglobulin and T lymphocyte subsets before and after treatment in the control group.During the treatment period,no adverse reaction occurred in two groups.Conclusion In summary,Montmorillonite combined with Compound Eosinophil-Lactobacillus Tablet had a good effect on AAD.They could quickly improve the symptoms of diarrhea and immunoglobulin levels in children.It was worthy of clinical use.

BACKGROUND: Most of the literatures only reported that there is a great difference between diabetics who have a high 24-hour urinary albumin excretion rate and those without renal damage, but there is no obvious difference between cases of microalbuminuria and those without renal damage.OBJECTIVE: To probe into the relationship between diabetic nephropathy and osteoporosis.DESIGN: A case-control study.SETTING: Department of Endocrinology, West China Hospital of Sichuan University.PARTICIPANTS: According to the diagnostic standard set by the American Diabetes Association in 1997 (fasting blood glucose ≥ 7 mmol/L,postprandial blood glucose ≥ 11.1 mmol/L), 96 diabetic patients were selected, including 56 males ＜ 60 years old and 40 females who had not entered the menopausal period, excluding the influence of age and osteoporosis caused by menopause. The average age of the subjects was (48.7±10.5)years, their duration were from one month to twenty-one years with the aver age of (7.85±2.56) years, and their general information had no significant differences.METHODS: According to the urine albumine excretion rate and renal function, the patients were divided into four groups: normal albuminuria group (n=48), microalbuminuria group (n=28), macroalbuminuria group (n=15), renal failure group (n=5). The bone mineral densities of lumbar spines (L2-4), femoral neck, Ward's triangle and trochanter were detected with Dual energy X-ray absorptiometry, and then the fasting blood glucose,2-hour postprandial blood glucose, glycosylated hemoglobin A, alkaline phosphatase, calcium, phosphorus, blood urea nitrogen, creatinine and urine albumine excretion rate were compared between the patients with and without osteoporosis.MAIN OUTCOME MEASURES: The fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin A, alkaline phosphatase, calcium, phosphorus, blood urea nitrogen, creatinine and urine albumine excretion rate, as well as the bone mineral density, were observed in all the patients.RESULTS: The L2-3 bone mineral density in the macroalbuminuria group was significantly different from that in the microalbuminuria group (P ＜ 0.05). The proximal femur bone mineral density in the microalbuminuria group was significantly different from that in the normal albuminuria group (P ＜ 0.05). The bone mineral densities of proximal femur and lumbar spine in the renal failure group were significantly decreased as compared with those in the other groups (P ＜ 0.01). The disease course,glycosylated hemoglobin A, alkaline phosphatase and body mass index were significantly different between the patients with and without osteoporosis (P ＜ 0.05).CONCLUSION: The incidence rate of osteoporosis is increased with the aggravation of nephropathy, and diabetic nephropathy may be closely correlated with the decrease of bone mineral density and the occurrence of osteoporosis.

Objective To determine the level of defensins(HNP_(1-3))and interleukin-8(IL-8)in colon tissue of patients with ulcerative colitis(UC)and to explore the relationship between HNP_(1-3)and IL-8 and the severity of disease.Methods The level of HNP_(1-3)and IL-8 in colon mucosa of UC patients was detected by immunohistochemistry method.Results The levels of HNP_(1-3)and IL-8 in colon mucosa of UC patients were much higher than that of normal controls.The expression of HNP_(1-3)and IL 8 of UC patients was higher in involved mueosa than in corresponding normal mucosa.The expression of HNP_(1-3) and IL-8 was related to the extent of lesion and the degree of disease.The expression of HNP_(1-3)was significantly correlated with that of IL-8(r_s＝0.957,P＜0.01).Conclusions The induction of HNP_(1-3) and IL-8 was involved in process of inflammation and development of UC.Regulating mechanisms of HNP_(1-3)expression might be related with the induction of IL-8.

EC-SOD inclusion bodies was refolded on column using metal (Ni) affinity chromatography, based on the metal-binding property of His-tag. The effect of protein amount, urea removal speed and temperature on refolding was observed. We compared the different efficiency purified with Ni-sepharose and Heprain-sepharose affinity chromatography, and studied the stability of the refolded proteins. The results indicate that the inclusion bodies can be renatured with Ni-sepharose affinity chromatography. The increase of the protein amount and urea removal rate , the lower of the renaturation efficiency. Higher temperature was benefit to protein renaturation. Both the Ni-sepharose and Heprain-sepharose affinity column can be used to purified the refolded proteins, but purified by Heprain-sepharose affinity column the protein had higher activity. The activity of renatured protein was stable in 10 ℃～50℃,when pH10 its stability was lower significantly. In denaturating solution the stability of renatured protein was low.

0.05). Conclusions Ultrasound contrast agent Levovist improves signal of blood flow obviously. It increases the diagnostic accuracy for intracranial aneurysms and the level of confidence.

Objective To observe characteristic imaging of traumatic arteriovenous fistulas(TAVF) and to evaluate the methods of differential diagnosis of TAVF by Doppler ultrasonography. Methods Eleven patients suffering from TAVF were selected to have the examination of Doppler ultrasonography. The blood flow of arteriovenous fistulas, diameter, morphology and blood flow character of affected vessels were observed. Spectral of fistula and affected vessels were analyzed and compared with the healthy side. Results Localization of arteriovenous fistulas was observed directly in eight patients, which presented as intercepted wall of the affected vessels and irregular mosaic flashes flowing towards enlarged vein from artery. Pulsed wave Doppler showed unilateral continuant spectral with maximum velocity 300-390 cm/s when sampled in the fistula. Spectral analysis of proximal arteries of the fistula revealed high velocity and low resistance. Arterialized flow pattern was observed in affected veins. Proximal veins of the fistula revealed arterialized spectral with high velocity and low resistance. Reversed centrifugal blood flow was observed in the distal veins of the fistulas in 4 cases. Conclusions Unilateral shunt in both diastole and systole in the fistula and arterialized flow with high velocity in veins are characteristic presentation of TAVF. Color Doppler ultrasonography has great value in confirming diagnosis and differential diagnosis of TAVF.
