More than one hundred strains of marine molds have been isolated from the sediment and the sample of seawater collected from the South China Sea. By the first screening, more than 30 strains of marine molds which can inhibit tested fungi such as Candida albicans and Fursarium sp. were obtained.The results of the second screening showed those strains designed as B 4#-6、B 4#-3、1-B 6-6、1-B 6-10-5、1-B 6-22、C 2#-5、A 2-9 and 1-B 6-10 can produced extracelluar antifungi metabolic products and the crude extract of the strains 1-B 6-10-5 and B 4#-3 can inhibit the growth of many other species of fungi.

Mantidis Oötheca is commonly used Chinese medicine. Because of the used medicinal part is oötheca and many mantis species can yield ootheca, it is not possible to identify its original animal accurately. There is no unanimous conclusion about the corresponding relationship between Mantis and Mantidis Oötheca (Sangpiaoxiao). This relationship is the basis of the Mantidis Oötheca research. Our study combined the methods of artificial incubation oötheca and capture the living mantis to identify the species of Mantis and Mantidis Oötheca. The results showed that the origin insects of Mantidis Oötheca was Tenodera, Hierodula and Statilia genus insects. This has laid a foundation for further study of Mantidis Oötheca.

ObjectiveTo explore the prevalence and spectrum of β-thalassemia mutations in Fujian province,and to provide a reference for prenatal diagnosis and genetic counseling in this population.Methods Two thousand three hundred and one blood samples were randomly selected from 9 different areas of Fujian province from May 2008 to December 2010.PCR and reverse dot blot hybridization (RDB) were adopted for detection of the 17 common types of mutation,and the frequency of each genotype of β-thalassemia mutations was calculated.The β-globin gene of unknown positive samples were analyzed directly with DNA sequencing.Results Three hundred and fifty-nine cases were detected with β-thalassemia mutations of the 2301 copy blood samples submitted,and the detection rate was 15.60％ (359/2301).Of the mutated genes,12 different mutations were identified,namely IVS-2-654(C→T),CD41-42(-TCTT),CD17(A→T),-28(A→G),CD27-28(+C),CD26(G→A),CD71-72(+A),IVS-1-1(G→T),CD43(G→T),-29(A→G),initiation codon ATG→AGG and CD36(-C).Mutation frequencies were 46.54％ (175/376),33.24％ (125/376),9.31％ (35/376),5.05％ (19/376),2.13％(8/376),1.33％(5/376),0.80％(3/376),0.27％(1/376),0.27％(1/376),0.27％(1/376),0.53％(2/376),and 0.27％(1/376),respectively.The most common mutations were IVS-2-654 (C→T) and CD41-42 (-TCTT),which accounted for 79.78％(300/376) of total genetic mutations.In addition,a novel β-globin gene mutation CD36 (-C) allele was detected for the first time,the deletion of a nucleotide C at code 36 within exon 2 lead to a frameshift mutation that could result in a premature termination at code 60.Conclusions β-thalassemia mutations in Fujian province are complex with significant genetic heterogeneity.We present for the first time the detection of a new β-thalassemia mutation in the population:CD36(-C),which provides valuable information for genetic counseling and prenatal diagnosis in Fujian province.

OBJECTIVETo study the effects of glycyrrhetinic acid (GA) on the sodium ion channel currents (I(Na)) of rats' ventricular myocardial cells, and to explore its anti-arrhythmic mechanisms at the ion channel level.

METHODSSingle ventricular myocardial cells was isolated from SD rats. The whole cell patch clamp was used to record the effects of GA on I(Na) of rats' ventricular myocardial cells.

RESULTSGA could inhibit I(Na) of rats' ventricular myocardial cells dose-dependently. GA at 1, 5, and 10 micromol/L decreased I(Na) of rats' ventricular myocardial cells from (-4.26 +/- 0.15) nA to (-3.54 +/- 0.10) nA, (-2.19 +/- 0.09) nA, and (-1.25 +/- 0.08) nA, respectively. GA at 1, 5, and 10 micromol/L inhibited I(Na) by 16.08% +/- 2.3%, 50.82% +/- 3.56%, and 75.98% +/- 5.12%, showing statistical difference when compared with the control group (P < 0.05). GA at 10 micromol/L shifted I(Na) current-voltage curve more positively, but the activation potential and the peak potential were not changed.

CONCLUSIONGA inhibited the I(Na) of rats' ventricular myocardial cells dose-dependently, which was possibly associated with its antiarrhythmia effects.

Objective To explore the effects and safety of hemoperfusion(HP) therapy on tetramine poisoning in infants.Methods Thirty-five infants with tetramine poisoning were divided into two groups: HP group(n=18) and non HP group(n=17).The changes of blood tetramine concentration and clinical symptom improving of both groups after the treatment were observed together with the adverse effects of HP group.Results The average blood tetramine concentration of HP group was higher than that of non HP group(342.2?333.4 vs 117.9?50.8 ?g/L,P

Inhaled NO (iNO) has been shown to have beneficial effects on decreasing pulmonary inflammation, increasing function of surfactant and improving lung growth in prematurely born animal models. iNO has been gradually applied in the neonatal intensive care unit since its first use for persistent pulmonary hypertension (PPHN) in the early 1990's. Although many research findings have shown the benefits of iNO for hypoxic respiratory failure (HRF) of preterm infants, there is no certain evidence to support the routine use of iNO in premature infants. According to recent literature, the mechanism of iNO therapy, treatment scheme, iNO effectiveness and safety in premature infants were reviewed in this article, so as to provide bases for the clinical use of this treatment.

OBJECTIVETo bring forward a method to improve the prominence of the forehead contour.

METHODS16 patients(age 29-53 years, female 11, male 5) were treated through a bicoronal incision. Following the incision, the forehead soft tissues are reflected down to the level of the superior orbital rims with the protection to the supraorbital neurovascular bundles. To adjust the forehead contour, both superior orbital rims and frontal bossing was reduced by burring down the excess bone or removing the anterior wall of the forehead.

RESULTSThe operative effect were satisfactory during 3-12 months of follow-up. No recurrence or osteogenesis were found in the cases. Nasofrontal angle and forehead angle were normal. The prominence of the supraorbital ridges disappeared and forehead became nature.

CONCLUSIONCranioplasty via an osteomy or burring of the outer line of forehead bone are safe, compact and effective way to improve the prominence of the superior orbital rims or frontal bossing.

OBJECTIVETo explore a new method for mentoplasty.

METHODSThe bilateral prominent mandibular angle or outer lamina was resected through the intraoral approach. The resected bone fragments were shaped and rigid fixed to the chin with miniplates and screws.

RESULTSA total of 30 patients (28 females, 2 males) accepted chin augmentation with this method. The mandibular angle bone was used in 20 cases and the mandibular outer lamina was used in 10 cases. The operative results were satisfactory, and the patient's facial contour was improved substantially.

CONCLUSIONNo rejection reaction was found after this procedure. Chin augmentation with autogenous mandibular bone is an ideal method for genioplasty.
