By functional plates,16 strains which can produce?-mannana-se were isolated frnm 28 Bacillus spp.Using a pair of degenerated primers,the conserved fragments of?-mannanase gene from the selected strains were amplified by PCR.The obtained nucleotide fragments were sequenced and compared with the homologous?-mannanase genes in GenBank and a phylogenetic tree was generated.Comparing to the genes coding?-mannanase published,the cloned nucleotide fragments show the highest sequence identity between 62% and 98%.The genes coding fnr?-mannanase of Bacillus circulus have low identity while the?-mannanase genes of Bacillus subtilis and other Bacillus spp. have high identity.

· AIM: To summarize the clinical features of Chinese primary congenital glaucoma and to investigate the discrepancies of the clinical features between the Chinese and Indian patients.congenital glaucoma patients were reviewed. The clinical features were summarized as several quantifiable clinical parameters and the severity of the disease was evaluated. Both the quantified clinical features and severity were statistically compared with those of the Indian patients, which were cited from the previous published articles.included in the study. In Chinese patients, sex ratio (male to female )was about 2:1, family history was presented in 3 patients (7.5%) and consanguinity was found in one patient (2.5%). The main symptoms and signs observed in Chinese patients spanned a wide spectrum of manifestations. The most frequent signs noted on the initial examination were enlarged eyeball (42.5%) and decreased visual acuity (35.0%). Compared with Indian patients, Chinese patients had a later onset, a delayed diagnosis, more severe corneal changes and more severe optic nerve damages (P＜0.01). The combined tabeculectomy and trabeculotomy operation was preferred by both Chinese and Indian doctors whereas a higher proportion of Indian patients received the combined operation (P＜0.01). The proportions of the severity grade were different between Chinese and Indian patients. Most Chinese patients were in the severe grade while most Indian patients were in the very severe grade (P＜0.01).patients were sporadic and non-consanguineous.Compared with Indian patients, Chinese patients had a relative later onset, a delayed diagnosis and treatment.More attempts are needed in Chinese PCG prevention and treatment.

The marine biological source of mineral drugs recorded in Chinese Pharmacopoeia (2010 version) mainly including pearl, nacre, clam shell, common oyster shell, ark shell, cuttle bone, and sea-ear shell are widely used in clinical. Calcium carbonate and a small amount of protein are the main components in this type of drugs. In this paper, a systematical and comparable study were carried out by determination of calcium carbonate by EDTA titration method, the crystal of calcium carbonate by X-Ray powder diffraction and the total amino acids (TAAs) of the hydrolyzed samples by ultraviolet spectrophotometry method. As a result, the crystal structure is calcite for common oyster shell, mixture of calcite and aragonite for nacre and sea-ear shell, aragonite for the other drugs. The content of calcium carbonate ranged from 86% to 96%. Cuttle bone has the highest amount of TAAs among the seven drugs which reached 1.7% while clam shell has the lowest content of 0.16% on average. In conclusion, an effective method was developed for the quality control of marine mineral drugs by comprehensive analysis of calcium carbonate and TAAs in the seven marine mineral drugs.

Growing attention on the rare diseases promotes the work of the government legislation, so a series of rare diseases related policies have been introduced. However, under the conditions of economy, population, social security and so on, China’s rare disease medical care and drug development are still in the initial stage. This paper elaborates and analyzes the status and future development of rare disease drugs, and provides advice for the policy formation of rare diseases and industrial development.

Objective To evaluate tear ferning changes of conjunctivochalasis.Design Prospective case study series.Partici- pants 30 patients(60 eyes)of conjunctivochalasis and normal subjects were selected.Methods The subjects were observed with gen- eral ophthalmic examination and tear fern test(TFT).Tear ferning was classified into 4 types.TypeⅠand TypeⅡare normal.TypeⅢand TypeⅣare abnormal.Main Outcome Measures The type of tear feming.Results TFT showed that tear ferning was de- creased in conjunctivochalasis group(TypeⅢand TypeⅣoccupied 61.7%).The difference between conjunctivoehalasis and normal control group was significant(P

OBJECTIVETo establish and evaluate chronic heart failure (CHF) rat model of Xin-qi deficiency complicated blood stasis and edema syndrome (XQD-BSES).

METHODSTotally 40 SD rats were randomly divided into the normal control group (Control), the propylthiouracil (PTU) group, the adriamycin (ADR), and the ADR + PTU group. Normal saline was used as equivalent solvent of each group. Rats in the Control group were intragastrically and intraperitoneally injected with normal saline. Rats in the PTU group were intragastrically injected with PTU suspension and intraperitoneally injected with normal saline. Rats in the ADR group were intragastrically injected with ADR solution and intraperitoneally injected with normal saline. And rats in the ADR + PTU group were intragastrically injected with PTU suspension and intraperitoneally injected with ADR solution. The dose of PTU was 0.2% of daily forage weight, once daily. The dose of ADR was 3.5 mg/kg, once per week. The modeling lasted for 6 weeks. Left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), brain natriuretic peptide (BNP), heart rate (HR), respiratory rate (RR), urine output, ear temperature, exhaustive swimming test (EST), Tri-iodothyronine (T3), tetra-iodothyronine(T4), thyroid stimulating hormone (TSH) as well as heart, lung, liver weight indices and their pathological sections were integrated and compared.

RESULTSCompared with the Control group, LVEF, LVFS, BNP, HR, RR, heart, lung, liver weight indices, urine output, ear temperature, EST, and T3, T4, and TSH changed significantly in the ADR group, the PTU group, and the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure occurred in pathological sections of heart, lung, and liver. Compared with the ADR group, LVEF, LVFS, BNP, and lung, liver weight indices, urine output, ear temperature, T3, T4, and TSH changed significantly in the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure were more serious in pathological sections of heart, lung, and liver. Compared with the PTU group, LVEF, LVFS, BNP, HR, RR, urine output, EST, T4, heart and lung weight indices changed significantly in the ADR + PTU group with statistical significance (P < 0.05), and pathological changes of heart failure were quite serious in pathological sections of heart, lung, and liver.

CONCLUSIONADR + PTU was an appropriate method to establish CHF rat model of XQD-BSES.

OBJECTIVETo examine serum 25-hydroxyvitamin D levels in children with attention deficit hyperactivity disorder (ADHD) and to explore the relationship between vitamin D level and ADHD.

METHODSNinety-seven children with ADHD who were diagnosed according to DSM-V were selected as the ADHD group, including 46 cases of ADHD-I, 10 cases of ADHD-HI, and 41 cases of ADHD-C. Ninety-seven healthy children served as the control group. Serum levels of 25-hydroxyvitamin D were measured using electrochemiluminescence immunoassay.

RESULTSMean serum levels of 25-hydroxyvitamin D in the ADHD group (17±7 ng/mL) were significantly lower than in the control group (23±8 ng/mL; P<0.01). The serum levels of 25-hydroxyvitamin D in the three subtypes groups of ADHD (ADHD-I, ADHD-HI, and ADHD-C) were all lower than in the control group (P<0.05). The rates of vitamin D insufficiency, deficiency or normal in the ADHD group were different from the control group (P<0.01). The distributions of vitamin D levels in the three subtypes groups of ADHD were all different from the control group (P<0.05).

CONCLUSIONSSerum levels of 25-hydroxyvitamin D in children with ADHD are lower than in healthy children, suggesting vitamin D level might be related to ADHD.
