Objective To study the MRI manitestation of juvemle acute pure cartilage fracture of the knee joint.Methods The MRI changes of cartilage,subcartilage low signal line and subcartilage bone were analysed retrospectively in 26 juvenile patients with acute pure cartilage fracture confirmed by arthroscopy.Sagittal and coronal MRI scanning were performed in 26 patients.Using fast low angle shot fat saturation T_1-weighted image(FLASH-FS-T_1WI)sequences,spin echo T_1-weighted image(SE-T_1WI)and fast imaging with steady-state precession three dimensional fat saturation T_2-weighted image(FISP-3D-FS- T_2WI)sequences in sagittal plane,SE-T_1WI and multi echo data image combination T_2-weighted imaging (MEDIC or ME-T_2WI)in coronal plane.Using ME-T_2WI sequence,axial plane MRI scanning in 5 patients.Results Twenty-seven sites of 26 patients include 8 patella,7 femoral medial condyle, 11 femoral lateral condyle and 1 tibial plateau.Three types pure cartilage fracture were observed,totally defect of the cartilage in 7 sites(include 3 patella,2 femoral medial condyle,1 femoral lateral condyle and 1 tibial plateau),fissuring fracture in 3 sites(include 2 femoral medial and 1 femoral lateral condyles), superficial defect of the cartilage in 17 sites(include 5 patella,3 femoral medial and 9 femoral lateral condyle).Corpus liberum was found in 21 patients'knee joints by arthroscopy,but only 3 cases by MRI. Bone bruise was detected,and subcartilage low signal lines were normal.Conclusion Using FLASH-FS- T_1WI,SE-T_1WI,FISP-3D-FS-T_2WI and ME-T_2WI sequences,sagittal and coronal MRI scanning in femoral and tibial plateau pure cartilage fractures,and using ME-T_2WI sequence axial scanning in patella r cartilage fractures may show the position,extension and types of the acute pure cartilage fracture of the knee joint. MRI is the hest non-invasive method for studying cartilage fracture.

Objective To provide basis for routine fetal cardiac screening by comparing the ultrasound detection rate of fetal heart defects between the high-risk and low-risk population.Methods According to the questionnaire about maternal risk factors,all 7165 pregnant women were divided into two groups.The high-risk group included 2147 cases and the remained 5018 were considered as low-risk population.Routine fetal heart screening was performed by the four-chamber view,left and right outflow tract views.If some cardiac malformations were found,the detailed fetal echocardiography would be performed.Both the detection rate of fetal cardiac defects and distribution of the relevant risk factors were analyzed.Results Ninty-five(1.33%)cases of congenital heart disease were found in our study,32(1.49%)cases from highrisk group and 63(1.26%)cases from low-risk group.No significant was found between the two groups (X2=0.635,P＞0.05).Karyotyping were performed prenatally in 23 of 95 fetal congenital defects cases by cordocentesis and chorionbiopsy,and 11(47.83%)cases of concomitant chromosomal abnormality were found.Conclusions Routine fetal screening for congenital fetal diseases should be performed in non-selected population for the similar detection rate of fetal defect in high-risk and low-risk group.

Objective To investigate the clinical features of glucose transporter 1 deficiency syndrome(GLUT1-DS) and summarize the characteristics of GLUT1-DS through reviewing related references.Methods The clinical data including manifestation,cerebrospinal fluid (CSF) glucose,electroencephalogram,MRI and gene mutation of a patient with GLUT1-DS was collected and the related literatures were reviewed.Results The patient was a 6 years old boy.The patient,whose seizures occurred at the age of 9 month-old and prolonged to 6 year-old,attacked before breakfast.Physical examination showed microcephaly with head circumference 47.5 cm.Laboratory tests showed that CSF glucose decreased (1.87 mmol/L) and CSF-serum ratio was 0.36.And meantime the MRI was normal and electroencephalogram showed general spike and slow wave complex paroxysm.Mutation of SLC2A1 gene,c.350_385del,was found in the patient.There were 219 cases with GLUT1-DS had been reported and the age of onset was 15.69 months.In 219 patients,159 cases (72％) suffered seizures,105 cases (47％) had motor abnormalities,61 cases (27％) suffered intellectual disability.The CSF glucose values were (1.92±0.31) mmol/L,CSF-serum ratio was 0.36±0.07.SLC2A1 gene mutations were detected in 183 patients(96％)in which missense mutation was the most mutation.Conclusion A wide range of phenotypes of GLUT1-DS include seizures,motor abnormalities,mental retardation.The diagnosis is confirmed when CSF glucose and CSF-serum ratio are continuously decreased which in the absence of meningitis.The SLC2A1 gene should be detected in suspicion of GLUTI-DS patients.Early diagnosis and treatment may improve the prognosis of those GLUTI-DS patients.

Objective To evaluate development of gastro-esophageal reflux (GER) during laparoscopic surgery in lateral jack-knife position under general anesthesia through comparing with reverse Trendelenburg/ Trendelenburg position in the patients lying supine.Methods Ninety patients of both sexes,aged 18-64 yr,of ASA physical status Ⅰ or Ⅱ,with body mass index of 18-30 kg/m2,scheduled for elective laparoscopic surgery under general anesthesia,were randomly divided into 3 groups (n =30 each):lateral jack-knife position group (group L),Trendelenburg position group (group T) and reverse Trendelenburg position group (group Tre).Anesthesia was induced with midazolam,sufentanil,propofol and cisatracurium besylate and maintained with propofol and remifentanil given by target-controlled infusion.A pH-sensitive probe was inserted through nose into the lower esophagus and pH value was continuously recorded until 1 min after extubation.GER was defined as pH value ≤ 4 lasting for ≥ 1 min in the lower esophagus during surgery.The development of GER during surgery and the lowest pH value in the lower esophagus when GER developed were recorded.Results Compared with group Tre,the incidence of GER (27％) and total number of times GER had occurred were significantly increased in group L,and no significant changes were found in the indices mentioned above in L and T groups.When GER developed,the lowest pH value in the lower esophagus was 2.1 ± 1.3,2.6 ± 1.2 and 3.5 in L,T and Tre groups,respectively.Conclusion The incidence of GER is 27 ％ during laparoscopic surgery when the patients are in lateral jack-knife position and it is higher than that obtained with reverse Trendelenburg position in the patients lying supine.

Objective To observe the effect of continued nursing on the long-term nasal feeding to elderly patients after discharge.Methods Toally 60 elderly discharged patients between January 2014 to December 2014 were evenly divided into observation and control groups with radom digit table the control group received routine nursing before discharge and after it and the observation group received continued nursing.The two groups were compared in terms of nasal feeding-induced complication,nursing satisfaction,care capability of patients' caregivers.Result The complication rate in the observation group was significantly lower,the nursing satisfaction was significantly higher and the care capability of caregivers were significantly better as compared to those of the control group (P ＜0.05).Conclusion Continued nursing can improve nursing satisfaction,train the care capacity of caregivers,reduce the complications for the old patients who need long-term nasal feeding after discharge.

AIM: To observe the effect of Retinervus luffae fructus (RLF) on the myocardial ischemia in mice. METHODS: Mice were supplied with RLF (166.7,333.3, 666.7 g/L) twice daily (0.01 mL/g, ig). One week later, 30 U/kg pituitrin was injected intraperitoneally. The electrocardiogram was recorded, and the content of lactose dehydrogenase (LDH) in the serum and the activities of superoxide dismutase (SOD), maleicdialdehyde (MDA) in the myocardium were examined. RESULTS: RLF reduced the height of T wave in electrocardigram in myocardial ischemia mice and inhibited the decrease in heart rate. RLF also reduced the content of LDH in serum and the content of MDA in myocardium. The increase in the activity of SOD in myocardium was also observed. CONCLUSION: RLF may protect myocardium against ischemia injury. The mechanism may be related to the increase in activity of SOD and the suppression of the lipid peroxidation.

CC chemokine receptor 4 (CCR4) is a kind of G-protein-coupled receptor, which plays a pivotal role in allergic inflammation. The interaction between 2-(2-(4-chloro-phenyl)-5-{[(naphthalen-1-ylmethyl)-carbamoyl]-methyl}-4-oxo-thiazolidin-3-yl)-N-(3-morpholin-4-yl-propyl)-acetamide (S009) and the N-terminal extracellular tail (ML40) of CCR4 has been validated to be high affinity by capillary zone electrophoresis (CZE). The S009 is a known CCR4 antagonist. Now, a series of new thiourea derivatives have been synthesized. Compared with positive control S009, they were screened using ML40 as target by CZE to find some new drugs for allergic inflammation diseases. The synthesized compounds XJH-5, XJH-4, XJH-17 and XJH-1 displayed the interaction with ML40, but XJH-9, XJH-10, XJH-11, XJH-12, XJH-13, XJH-14, XJH-3, XJH-8, XJH-6, XJH-7, XJH-15, XJH-16 and XJH-2 did not bind to ML40.Both qualification and quantification characterizations of the binding were determined. The affinity of the four compounds was valued by the binding constant, which was similar with the results of chemotactic experiments. The established CEZ method is capable of sensitive and fast screening for a series of lactam analogs in the drug discovery for allergic inflammation diseases.
