The hybrid PET/MR has a unique advantage of simultaneous scanning of both PET and MRI images,which has been gradually applied in clinical practice.In the clinical studies of severe brain diseases (such as cerebrovascular disease,brain tumor and epilepsy),accurate quantification of cerebral blood flow (CBF) can help to understand the etiology,pathogenesis,and to make early diagnosis as well as therapeutic solutions.The hybrid PET/MR can implement a noninvasive,convenient and accurate method of arterial input function for quantification of CBF.The application of the hybrid PET/MR in quantification of cerebral blood flow were reviewed in this article.

Objective To investigate the effect of intralesional lauromacrogol therapy on infantile hemangioma.Methods 30 cases all received intralesional injection of lauromacrogol.The changes of tumor size,texture and color were monitored and recorded.The adverse effects after medication were observed and managed accordingly.The adverse effects after medication were observed.The times of treatment were determined according to degree of reduction of tumor volume.To assess the efficacy,a 4 scales system was adopted.Results All patients had completed the treatment and followup.The overall response was scale Ⅰ in 2 cases (6.7 ％),scale Ⅱ efficacy in 4 patients (13.3 ％),scale Ⅲ efficacy in 5 cases (16.7 ％) and scale Ⅳ in 19 cases (63.3 ％).The smaller the tumor,the fewer the times of treatment,and the better the results.The effects of treatment were better if patient could be treated by intralesional lauromacrogol therapy in early stage.No severe adverse effects were observed during 6 months of follow-up.Conclusions Intralesional injection of lauromacrogol sclerotherapy is a safe and effective way to treat infantile hemangioma.

Objective To analyze the relevant risk factors of recurrent wheezing(≥3 attacks) in the first 3 years of life in Shanghai Pujiang.Methods A case-control study was conducted.Two hundred and sixty-two research children were chosen for clinical visits (＜ 3 years old) with wheezing at the Pediatric Department of Shanghai Renji Hospital (South Campus),School of Medicine,Shanghai Jiaotong University,from January to December 2014.According to the frequency of wheezing,the subjects were divided into 75 cases of recurrent wheezing group (≥ 3 attacks),110 cases of occasional wheezing group(1-2 attacks) and 77 cases of no wheezing group.Probable risk factors were inquired by using face-to-face questionnaire.The passive agglutination method was used to detect the Mycoplasma pneumoniae antibody immunoglobulin M (IgM).The indirect immunofluorescence was used to detect the respiratory pathogens.The Western blot was used to detect 20 items of serum allergen.Chi-square test was firstly used for univariate analysis,and then the multivariate stepwise Logistic regression was used to analyze the independent risk factors associated with infant recurrent wheezing.Results A total of 20 factors were found relevant to infant recurrent wheezing by univariate analysis,which included boys (OR =4.030,95％ CI:1.937-8.388),personal atopy (OR =13.125,95％ CI:5.951-28.946),allergic dermatitis (OR =9.833,95％ CI:4.663-20.737),allergic rhinitis (OR =40.327,95％ CI:5.300-306.842),like rubbing eyes or nose(OR =6.487,95％ CI:3.190-13.191),food allergy (OR =6.689,95 ％ CI:1.860-24.051),premature birth (OR =3.795,95 ％ CI:1.001-14.385),low birth weight (OR =9.075,95％ CI:1.106-74.450),parental atopy (OR =10.667,95％ CI:4.824-23.587),parental allergic dermatitis (OR =8.072,95 ％ CI:2.634-24.734),parental allergic rhinitis (OR =6.524,95 ％ CI:2.920-14.577),parental allergic conjunctivitis (OR =1.087,95％ CI:1.017-1.162),parental asthma history (OR =1.119,95％ CI:1.035-1.210),colds ＞ 6 times (OR =9.111,95％ CI:3.970-20.909),history of bronchopneumonia(OR =7.554,95％ CI:3.588-15.903),age at first time use of antibiotics less than 6 months (OR =2.388,95％ CI:1.129-5.052),exposure to cigarette smoking (OR =1.922,95 ％ CI:1.004-3.681),maternal passive smoking during pregnancy (OR =2.508,95 ％ CI:1.298-4.848),living close to wood stove (OR =3.342,95 ％ CI:1.427-7.827) and positive results of inhaled allergens (OR =1.821,95 ％ CI:1.420-2.336).Keeping cats was the protective factor(OR =0.922,95％ CI:0.864-0.984).The forward Logistic regression analysis showed that personal atopy (OR =10.278,95 ％ CI:2.503-42.202),like rubbing eyes or nose (OR =1 0.316,95 ％ CI:2.722-39.101),food allergy (OR =10.370,95％ CI:1.248-86.145),parental atopy (OR =5.402,95％ CI:1.340-21.778),colds ＞ 6 times (OR =7.048,95 ％ CI:1.688-29.423),history of bronchopneumonia (OR =7.876,95 ％ CI:2.040-30.407) and maternaal passive smoking (OR =3.696,95 ％ CI:1.013-13.494) during pregnancy were the independent risk factors of infants recurrent wheezing.Conclusion Personal atopy,like rubbing eyes or nose,food allergy,parental atopy,colds ＞ 6 times,history of bronchopneumonia,maternal passive smoking are the independent risk factors of recurrent wheezing in infants less than 3 years old.

This paper employed UPLC-Electrospray Ionization /Quadrupole-Time of Flight-Mass /Mass Spectrometry( UPLC-ESI/Q-TOF-MS/MS) to analyze the chemical constituents in the stems of Nelumbo nucifera. The stems of N. nucifera were extracted with 75% methanol, and we applied an Agilent Zorbax SB-Aq column (2.1 mm x 100 mm, 1.8 μm) to UPLC analysis with water methanol-water( containing 0.05% formic acid) in gradient as mobile phase. The eluates were then detected by ESI-Q-TOF-MS/MS. Results indicated that 22 benzylisoquinoline alkaloids were indendified. Among them, one alkaloid may be a new compound and a component was found in the Lotus for the first time. We fully identify the composition of the Lotus stems for the first time, Which could provides theoretical foundation for further study and utilization of the medicinal resources.

BACKGROUND:Lithium chloridecan promote the proliferation and osteogenic capacity of bone marrow mesenchymal stem cels in the necrotic region after avascular necrosis of the femoral head, which has become an issue of concern. OBJECTIVE:To compare the advantages and disadvantages of bone marrow stem cel transplantation combined with lithium chloride in the treatment of rabbit femoral head necrosis. METHODS: Passage 2 bone marrow mesenchymal stem cels from 1-week-old New Zealand rabbits were cultured in 0, 5, 10, 20, 40 mmol/L lithium chloride. Forty-eight healthy adult New Zealand rabbits were selected to make femoral head necrosis models in the right femoral head using liquid nitrogen freezing method and then randomized into four groups: model group with no implantation; lithium chloride group given lithium chloride treatment at 3 days after modeling; cel transplantation group given gelatin sponge implantation and bone marrow mesenchymal stem cel suspension injection into the femoral head after modeling; combined group given bone marrow mesenchymal stem cel suspension injection and lithium chloride treatment. Intraperitoneal injection of lithium chloride (45.2 mg/kg) was given daily beginning at the postoperative 3rdday, and the treatment duration was 4 weeks. RESULTS AND CONCLUSION:Lithium chloride at 10 mmol/L had the maximum effect on the proliferation of rabbit bone marrow mesenchymal stem cels, and if the concentration of lithium chloride was > 10 mmol/L, the promotion role of lithium chloride began to decline. After combined treatment, the morphology of the femoral head was restored a little, with increased bone density and thickened trabecular bone; the level of β-catenin in the femoral head was significantly increased in the combined group compared with the cel transplantation group or the lithium chloride group. These findings show that bone marrow stem cel transplantation combined with lithium chloride treatment can promote the recovery from femoral head necrosis by increasing bone mass of the trabecular bone and bone density of the femoral head in the necrotic region.
