As known so far,Sporosarcina pasteurii,or formally termed as Bacillus pasteurii,was considered as one of the most efficient biosystem which is capable of inducing biological mineralization through breaking down urea.Taking advantage of the ‘super power’ of bio-mineralization,Sporosarcina pasteurii has been successfully utilized in application of solidifying sand as a novel biological construction technology,termed as ‘bio-cementation’ Due to the nature of Sporosarcina pasteurii isolated from soil,non-pathogenicity has been observed,it was considered as a very environmentally friendly method.Recently,Sporosarcina pasteurii has been further applied into fields including environmental improvement and biomedicine.However,the mechanism under the strong Sporosarcina pasteurii mediated bio-mineralization is still not well understood.Here,the knowledge and the up-to-date studies about the biological mechanism of Sporosarcina pasteurii mediated bio-mineralization,and the utilization in construction,environment,and biomedicine are reviewed.

OBJECTIVE: To establish Caco-2 (a human colon adenocarcinoma cell line) cell monolayer model and the standard operation procedure for studying and assessing intestinal absorption of chemical components of traditional Chinese medicine. METHODS: Caco-2 cell monolayer model was established and evaluated by morphology feature using scanning electron microscope, inverted microscope and transepithelial electrical resistance (TEER) assay. Additionally, the model was further tested for the activity of alkaline phosphatase and the apparent permeability (Papp) of standard compounds, i.e. propranolol and atenolol, which were the control substances for high and poor transcellular transport marker, respectively. RESULTS: The integrality of cell monolayer, cell differentiation (reflected by expression of alkaline phosphatase and cell monolayer morphology), and the Papp value of standard compounds in the established Caco-2 cell model were satisfactory. All parameters tested were in good agreement with those reported in the literature. CONCLUSION: The established Caco-2 cell model can be used to study the intestinal absorption of orally administrated chemical components of traditional Chinese medicine and their absorption mechanism.

AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.

Objective To detect the type of gene mutation of thalassemia in Kunming city.Methods Sixty-three cases highly suspec-tive of thalassemia were determined with the methods of ploymerase chain reaction(PCR) and reverse dot blot(RDB) for the type of gene mutation.Results According to gene analysis,35 cases were final diagnosed from 63 cases suspective of thalassemia.Among the total,4 cases were gene deficiency ?-thalassemia,and 30 cases were gene deficiency ?-thalassemia,and there was 1 case both ?-thalassemia and ?-thalassemia.There were 9 types of gene mutation with 15 gene combinations in 35 samples.The main type of ?-thalassemia was--SEA/??,there were 6 types with 11 gene combinations from the types of genes of ?-thalassemia,the highest incidence of gene mutation was 17 site,including 17 site homozygote,heterozygote and double heterozygote.Conclusions The thalassemia invasion of Yunnan has its characters,and it is valuable to launch further research.In the same patient,there are ?-thalassemia and ?-thalassemia,it signifies that those 2 types should be diagnosed in the same time,to prevent missed diagnosis.

OBJECTIVE: To compare the anesthesia properities of hyperbaric bupivacaine with those of isobaric and hypobaric solutions when administered in the supine position undergoing hip surgery or lower limb surgery using continuous spinal anesthesia. METHODS: Sixty patients( ASA I approximately III ) scheduled for hip or lower limb surgery were randomly divided into 3 groups with 20 patients in each group: Group A: 0. 375% hyperbaric bupivacaine solutions; Group B :0.375% isobaric bupivacaine solutions; and Group C: 0. 375% hypobaric bupivacaine solutions. The following variables were measured every 2 minutes during the first 30 minutes after the intrathecal injection : the onset time of sensation block, the highest plane of analgesia, the time to reach complete motor blockade, and the plane of analgesia and the extent of lower extremities' movement (modified bromage score, BMS) at different time after the administration. Meanwhile the changes of hemodynamics were recorded. RESULTS: There was no statistical difference among the basic conditions ( P > 0.05). The onset time of sensation block, and the time to reach complete motor blockade, and the time receiving the highest sharp pain sensory block in Group A were significantly shorter than those in Group B and Group C ( P < 0.01 ). The plane of analgesia obtained in the hyperbaric group was significantly higher than in both the isobaric and the hypobaric groups ( P < 0.01). The mean arterial pressure(MAP) , HR in the hyperbaric group decreased significantly after the intrathecal injection( P < 0.05 ). CONCLUSION The 0.375% Isobaric bupivacaine used during contiuous spinal anesthesia in the supine position produces a suitable and a more "controllable" anesthesia, but a minimum dosage of 10 approximately 12.5 mg is required to obtain adequate anesthesic conditions with moderate hemodynamic changes and satisfying analgesia effects. Under similar conditions, 0. 375% hyperbaric bupivacaine produces major hemodynamic consequences with high cephalad spread and 0. 375% hypobaric bupivacaine has a too long onset time.

Viral hepatitis was the most common infectious disease in china. But the diagnosis and treatment were varied because the viral hepatitis patients were hospitalized in different kinds of hospital such as infectious disease hospital, general hospital and Chinese medical hospital. It was necessary to know clinical characters and information of viral hepatitis patients in different hospitals. The general information, subtype distribution, prognosis, complication, medication and relations of onset with solar term from 41 180 viral hepatitis patients based on HIS data were analyzed. It was found that the age of patients between 18 to 59 years old was most; most patients were males. The national basic medical insurance was the most type of payment. The outcome of viral hepatitis in the youth and female were better than that in the old and male. Acute hepatitis was easer to restore than chronic hepatitis. Liver cirrhosis and hepatocellular carcinoma were the two most complications. The peak of onset was during summer solstice, slight heat and great heat. The most common Chinese medicine was Diammonium glycyrrhizinate and the most common western medicine was reduced glutathione. The combination of D. glycyrrhizinate with reduced glutathione, polyene phosphatidylcholine and thymosin was the main pattern. But It was not knew if the combination of western and Chinese medicine was the most effective therapy to protect liver function. It was necessary to take deeply research of the relationship between the combination therapy and their effectiveness.

OBJECTIVETo investigate the relationship between UNC5b gene expression and angiogenesis of hepatocellular carcinoma (HCC).

METHODSIn situ hybridization was performed to detect the expression of UNC5b mRNA in HCC samples, paracarcinomatous liver tissues samples and normal liver samples. The relationship between UNC5b mRNA expression and the HCC clinicopathological features were also analyzed. Human umbilical artery endothelial cells were isolated and stimulated with HCC tissues homogenate, vascular endothelial growth factor and basic fibroblast growth factor. Then RT-PCR was employed to detect the expression of UNC5b mRNA in normal HUAEC as well as activated HUAEC.

RESULTSIn situ hybridization results showed that UNC5b mRNA expression was detected majorly in endothelial cells of all normal liver tissues, and partial PCLTs but was weak or even undetectable in endothelial cells of the corresponding HCC tissues. The expression levels of UNC5b gene in PCLTs were significantly correlated with capsular formation of HCC. Furthermore, RT-PCR results showed that the expression levels of UNC5b mRNA in activated HUAEC were significantly higher than those in normal HUAEC.

CONCLUSIONSDown-regulation of UNC5b gene expression is related to angiogenesis of HCC, which may be associated with the progression of HCC.
