The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.

Objective To explore the clinical characteristics ,diagnosis, treatment and prognosis of phaeohyphomycosis. Methods Clinical data were collected, including history, physical examination, cranial and spinal imaging. Brain biopsy was performed. Data of the pathology and incubation of brain tissue were analyzed. Responsiveness to treatment was followed up. Results A previously healthy three and half years old boy was presented to our unit, with a three- month history of recurrent headache, vomiting, progressive paraplegia accompanied by urinary continence and constipation. A computed tomogram scan and magnetic resonance imaging of the brain revealed multiple lesions located in the region of the parietal - occipital lobes, periventricular area and frontal lobe, with prominent surrounding edema and irregular peripheral enhancement of the mass after the administration of contrast materials. A cerebral biopsy was performed and the pathological report was cerebral phaeohyphomycosis. The culture of the tissue and cerebrospinal fluid grew a same fungus identified as exo-phiala dermatitidis. The patient's response to therapy was poor, the parents of the boy gave up therapy, and the boy died 1 month later. Conclusions Cerebral Phaeohyphomycosis caused by Exophiala dermatitidis is rare, but the most serious form of fungus infection. Pathology and incubation of the tissue are essential for diagnosis. There is no curative therapy and the prognosis is poor.

Abstract: Objective　To analyze the emergency response and long-term intervention effects after the detection of infectious snails epidemic by loop-mediated isothermal amplification (LAMP) assays in Hannan District, Wuhan City, and to explore the application of LAMP in early surveillance and early-warning of schistosomiasis transmission. Methods Snails picked up by the risk monitoring system in Hannan District were examined by anatomical microscopy and LAMP technology to identify the schistosomiasis infection. Emergency response and intensive intervention were initiated in the environment where positive snails appeared, and the long-term effects were evaluated. Results In May 2018, the infectious snails were detected by LAMP technology in Hannan District, and the positive snails were located in Zhujiacha, Dongzhuang Village, Obstacles and weeds were removed and buried by machine in Zhujiacha. 12 700 m2 of snails were killed by drugs, and the mortality rate of snails was more than 80%; no new seropositive persons were found in the emergency examination within 500 m of the positive snail sites. 506 people were examined in Dong Zhuang Village at the end of the year, and 30 positive IHA cases were detected with a blood positive rate of 5.93%, no positive fecal test was found, and all positive blood test patients took preventive medication. The monitoring results of sentinel rats and wild feces were all negative. Health education was carried out, 7 warning signs were deployed and refreshed, and 500 publicity brochures were distributed. After nearly three years of intensified intervention and monitoring in the villages where the positive environment is located, and the density of snails on the stubborn snail has dropped from 0.094/frame to 0.027/frame, and the positive rate of blood test in Dongzhuang Village has steadily dropped from 5.93% to 3.74%. Conclusions The infected snails missed by microscopy were detected by LAMP in Hannan District, which created conditions for the rapid emergency treatment of environment and elimination of positive snail and improved the sensitivity of the surveillance and early warning system in transmission-interrupted areas.

Objective To investigate the prevention of glucocorticoid-induced osteoporosis or bone loss in systemic lupus erythematosus (SLE) patients by Bugu capsules.Methods Sixty-six patients with SLE were randomly divided into A and B groups:34 patients in Group A were treated by glucocorticoid and Bugu capsules,and 32 patients in Group B by glucocorticoid alone.All patients were measured for bone mineral density (BMD) in Wards triangle,and for related biochemical parameters such as serum calcium, phosphonium,alkaline phosphatase,parathyroid hormone (PTH) and interleukin-6 (IL-6) before and after the treatment.As the control group,thirty healthy subjects were measured for the above parameters.Results There was significant difference in the serum level of IL-6,calcium and PTH between the Group B and con- trol group (P＜0.01).The occurrence rate of osteoporosis or bone loss in group A was significant lower than that in group B [2/34 (5.88%) vs 9/32 (28.13%),P=0.0364].Conclusion Bugu capsules can prevent glucocorticoid-induced osteoporosis or bone loss in SLE patients,possibly by restoring the balance among serum IL-6,calcium and PTH.

To analyze killer immunoglobulin (Ig)-like receptor (KIR) gene content and allelic polymorphism in Zhejiang Han population, samples were genotyped by polymerase chain reaction sequence-specific primers (PCR-SSP). The results demonstrated that all 17 KIR genes could be observed in the population. All individuals contained 2DL4, 3DL2 and 3DL3 genes. The frequencies of these genes was 1.00. 2DL1, 2DL3, 2DP1, 3DP1*003, 3DL1, 2DS4*001/002 loci were more common, their frequencies were 0.902, 0.902, 0.902, 0.902, 0.7598, 0.5615 respectively, while the frequencies of 2DL2, 2DL5A, 2DL5B, 2DS1, 2DS2, 2DS3, 2DS4*003, 2DS5, 3DS1 and 3DP1*001/002 were relatively lower. The A KIR haplotype was the most prevalent (74.7%) in Zhejiang Han population and there were 12 different KIR haplotypes in total, the most common was 2 (53.0%). Twenty six different genotypes have been found in the population, AJ (2, 2) and AF (1, 2) showed higher frequencies, followed by AH (2, 5), NN2 (2, 6), AI (1, 5) and AG (1, 1). Fifteen of these genotypes have not been found in Caucasians so far and four new KIR profiles could not be assigned to the haplotypes according to standard assign method. In conclusion, there are distinctive frequencies of KIR gene content, haplotype as well as genotype in Zhejiang Han population.

OBJECTIVETo investigate the molecular genetics basis for a novel HLA allele, HLA-B*5614, in Chinese population.

METHODSDNA was extracted from whole blood by salting-out method. The HLA-B exons 2-4 of the proband was amplified and the amplified product was cloned using TOPO cloning sequencing kit to split the two alleles apart. Both strands of exons 2,3 and 4 of chosen colonies were sequencing. The PCR-SSP was performed to confirm the mutations detected by sequencing.

RESULTSThe sequencing results showed the HLA-B alleles of the proband as B*1502 and the novel allele. The sequences of the novel allele have been submitted to GenBank (AY601726, AY610727, AY610728). After BLAST analysis, the novel allele differs from B*5608 by a single nucleotide at position 277G-->C in exon 2. This results in an amino acid change from Gly to Arg at codon 93.

CONCLUSIONThis allele is a novel allele and has been officially named B*5614 by the WHO Nomenclature Committee.
