Aim To elucidate the relationship between IgG antibodies and penicillin allergy.Methods Enzyme-linked immunosorbent assay was used to examine 8 kinds of specific IgG antibodies,including major antigenic determinants:benzylpenicilloyl(BPO),ampicilloyl(APO),amoxicilloyl(AXO)and phenoxomethylpenicilloyl(PVO),and minor antigenic determinants:benzyl-penicillanyl(BPA),amoxicillanyl(AXA),ampicillanyl(APA)and phenoxomethylpenicillany(PVA),in the sera of 241 patients with penicillin allergy.Results Except BPA-IgG,levels of 7 kinds of antigenic determinants IgG antibodies were significantly higher than those of control group(P

0.05). Conclusion IL-1? has a higher value than cagA gene in predicting the prognosis of chronic gastritis.

BACKGROUND:Drug therapy can partly reduce and delay the progress of Alzheimer’s disease, but only 30%with the single drug treatment obtain clinical cure. OBJECTIVE:To study the therapeutic effect of bone marrow mesenchymal stem cel s transplantation for rats with Alzheimer’s disease. METHODS:Amyloidβ-protein was injected into the hippocampus of Sprague-Dawley rats to construct the model of Alzheimer’s disease. And bone marrow stromal stem cel s were transplanted into the hippocampus of the rat models. RESULTS AND CONCLUSION:At 2 weeks after modeling, compared with the control group, the escape latency in the model and experimental groups was significantly longer (P<0.05), which indicating that Alzheimer’s disease models were successful y established. At 4 weeks after cel transplantation, compared with the model group, the average escape latency in the experimental group was significantly decreased, but retention time on the platform quadrant was significantly prolonged (P<0.05). Besides, at 4 weeks after cel transplantation, expression of choline acetyltransferase in the experimental group was significantly higher than that in the model group (P<0.05). In conclusion, bone marrow mesenchymal stem cel s cannot only differentiate and survive in the hippocampus of rats with Alzheimer’s disease, but also improve the learning and memory ability.

Objective To explore the clinical features of methylmalonic acidemia (MMA) in children admitted to the pediatric intensive care unit, to help improve our understanding of MMA. Methods The clinical data of 21 patients with MMA admitted to our PICU from December 2012 to August 2016 were analyzed. Diagnosis were confirmed by gas chromatography-mass spectrometry, GC/MS. Results twenty-four of 158 suspected cases were confirmed as having organic acidemia diseases including 21 cases of MMA, one case of propionic acidemia, one case of urea cycle disorders, and one case of glutaric acidemia. The main clinical manifestations were feeding difficulty, malnutrition (13 cases), developmental retardation (12 cases), lethargy (10 cases), tricuspid severe reflux and pulmonary hypertension (1 case), hydrocephaly (5 cases), muscular dystonia (three cases with hypertonia, and four with hypotonia), convulsion (7 cases), apnea, sobbing respiration (10 cases), chromatosis (6 cases), anemia (13 cases), edema (6 cases), thrombocytopenia (6 cases), hematuria and proteinuria (2 cases). Five cases gave up therapy before diagnosis was made. Sixteen cases received the treatment with Vitamin B12 and supplementation of L-carnitine. Seven cases gave up after treatment without effect or deterioration of condition. Eight cases were vitamin B12-responsive, and one case was vitamin B12-nonresponsive. The follow-up for a period ranging from three months to two years, among eight vitamin B12-responsive cases, 6 cases showed a favorable outcome with apparent improvement, one case had no symptom and one patient died from severe pneumonia. Vitamin B12-nonresponsive case was still alive. Conclusions The clinical manifestations of MMA are non-specific. Urine organic acid analysis is critical to early diagnosis of MMA in high-risk patients. Timely diagnosis and appropriate long-term treatment are essential to improve the prognosis of the disease.

OBJECTIVETo compare the differences in the efficacy on lower limb motor function in children with spastic cerebral palsy between the combined therapeutic program of Jin three-needle therapy and MOTOmed intelligent motor training and the simple MOTOmed.

METHODSEighty children with spastic cerebral palsy were randomized into an observation group and a control group, 40 cases in each group. In the observation group, Jin three-needle therapy was used at four mind points, three brain points, three intelligent points, three temporal points, three knee points and three foot points, as well as Chengjin (BL 56), Chengshen (BL 57) and the other. Additionally, MOTOmed was given in assistance with conventional rehabilitation training. In the control group, MOTOmed and the conventional rehabilitation training were adopted. In the two groups, the treatment was given once a day, 20 treatments made one session and there were 3 to 5 days at interval between the two sessions. The efficacy evaluation was performed after continuous 3 sessions of treatment. The gross motor function measure (GMFM) and modified Ashworth scale (MAS) were applied for the evaluation before and after treatment in the two groups.

RESULTSAfter 3 sessions of treatment, GMFM score was increased apparently as compared with that before treatment in the two groups (P < 0.01, P < 0.05). After treatment, GMFM score in the observation group was increased more remarkably than that in the control group (55.32 +/- 17.10 vs 47.48 +/- 17.18, P < 0.05). After treatment, the total effective rate of gastrocnemius Ashworth spasm grade [90.0% (36/40)] in the observation group was better apparently than [72.5% (29/40)] in the control group (P < 0.05).

CONCLUSIONThe combined therapeutic program of Jin three-needle therapy and MOTOmet intelligent motor training improves the lower limb motor function of the children with spastic cerebral palsy and its efficacy is better than simple MOTOmed.

The laser-induced breakdown spectroscopy (LIBS) was applied to perform a qualitative elementary analysis on four precious Tibetan medicines, i. e. Renqing Mangjue, Renqing Changjue, 25-herb coral pills and 25-herb pearl pills. The specific spectra of the four Tibetan medicines were established. In the experiment, Nd: YAG and 1 064 nm-baseband pulse laser were adopted to collect the spectra. A laser beam focused on the surface of the samples to generate plasma. Its spectral signal was detected by using spectrograph. Based on the National Institute of Standard and Technology (NIST) database, LIBS spectral lines were indentified. The four Tibetan medicines mainly included Ca, Na, K, Mg and other elements and C-N molecular band. Specifically, Fe was detected in Renqing Changjue and 25-herb pearl pills; heavy mental elements Hg and Cu were shown in Renqing Mangjue and Renqing Changjue; Ag was found in Renqing Changjue. The results demonstrated that LIBS is a reliable and rapid multi-element analysis on the four Tibetan medicines. With Real-time, rapid and nondestructive advantages, LIBS has a wide application prospect in the element analysis on ethnic medicines.

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a type of newly recognized autoimmune encephalitis which is commonly seen in children, but its precise etiology is still uncertain. To reveal the etiology of anti-NMDAR encephalitis is very necessary for understanding its pathology, and for starting immune-related therapy as early as possible to improve its prognosis. In the initial literature, tumor, especially teratoma is more related with the anti-NMDAR encephalitis. In recent research, its etiology is related to infection and heredity. This article reviews the recognition and variation of the etiology of anti-NMDAR encephalitis.
