OBJECTIVE:To evaluate the economics of somatostatin,ulinastatin,octreotide and gabexate preventing hyperamy-lasemia and pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). METHODS:Medical records of 316 cho-ledocholithiasis patients underwent ERCP were selected from our hospital during Jul. 2008-Apr. 2016,and then divided into blank control group(58 cases),somatostatin group(64 cases),ulinastatin group(65 cases),octreotide group(68 cases)and gabexate group (61 cases) according to the use of protease inhibitor. Before ERCP,blank control group received routine treatment as fast-ing,parenteral nutrition support,acid suppression,etc. Based on it,other 4 drug groups received prophylactic drug use according to package inserts 6 h before ERCP. The incidence of hyperamylasemia and pancreatitis after ERCP,VAS scores 3,24,48 h after surgery and the occurrence of ADR were compared among 5 groups. The cost-effectiveness analysis was used to evaluate the eco-nomics of therapy plans in each group. RESULTS:Compared with blank control group,hospitalization time of somatostatin group, ulinastatin group,octreotide group and gabexate group were shortened significantly;the incidence of hyperamylasemia and pancre-atitis were significantly decreased;VAS score 3,24,48 h after surgery were significantly decreased,with statistical significance (P<0.05). Compared among 4 groups,above indexes had no significant difference,and the incidence of ADR was in low level and had no statistical significance(P>0.05). The cost-effectiveness ratio of somatostatin group was the lowest and has cost-effec-tiveness advantage. The results were supported by incremental cost-effectiveness and sensitivity analysis. CONCLUSIONS:Soma-tostatin,ulinastatin,octreotide and gabexate can significantly prevent the occurrence of hyperamylasemia and pancreatitis after ER-CP,and relieve pain with good safety. Somatostatin can achieve the best therapeutic efficacy at the lowest cost,so it is the best plan for hyperamylasemia and pancreatitis after ERCP.

Background Granulocyte colony-stimulating factor(G-CSF)has been reported to have beneficial effect on cardiac dysfunction in post infarction and doxorubicin-induced cardiomyopathy.Objective To investigate the effects of G-CSF on cardiac remodeling in cardiac hypertrophy induced by angiotensin Ⅱ(Ang Ⅱ).Methods Thirty-six male wild type mice(WT)were allocated randomly to receive subcutaneously G-CSF(10 ?g/kg per day, n=9),or Ang Ⅱ(2.88 mg/kg per day,n=9),or Ang Ⅱ plus G-CSF(Ang Ⅱ 2.88 mg/kg+G-CSF 10 ?g/kg,n =9)for 4 weeks with untreated WT(n=9)as controls.Blood pressure and cardiac function were measured. Heart weight/body weight ratio,myocyte cross-sectional area and fibrosis area were determined.The mRNA ex- pression of osteopontin(OPN)in myocardium was detected by RT-PCR.The expressions of angiotensin converting enzyme(ACE),ACE2 and phosph-p70S6 kinase protein in myocardium were assessed by Western-Blot.Results Ang Ⅱ significantly elevated blood pressure(SBP,Ang Ⅱ:139.7?1.6 vs WT:108.7?2.3 mmHg,P0.05),but significantly attenuated the myocyte cross-sectional area(Ang Ⅱ+G-CSF:181.06?0.11 vs Ang Ⅱ:202.02?0.16 ?m~2,P

The objective of the study was to prepare and evaluate the quality of curcumin-piperinedual drug loaded self-microemulsifying drug delivery system(Cur-PIP-SMEDDS). Simplex lattice design was constructed using optimal oil phase, surfactant and co-surfactant concentration as independent variables, and the curcumin and piperine were used as model drugs to optimize Cur-PIP-SMEDDS formulation. In the present study, the drug loadings of curcumin and piperine, mean particle size of Cur-PIP-SMEDDS were made as indicators, and the experiment design, model building and response surface analysis were established using Design Expert 8. 06 software to optimize and verify the composition of SMEDDS formulation. The quality of Cur-PIP-SMEDDS was evaluated by observing the appearance status, transmission electron microscope micrographs and determining particle diameter, electric potential, drug entrapment efficiency and drug loading of it. As a result, the optimal formulation of SMEDDS was CapryoL 90-Cremophor RH40-TranscutoL HP (10:60:30). The appearance of Cur-PIP-SMEDDS remained clarified and transparent, and the microemulsion droplets appeared spherical without aggregation with uniform particle size distribution. The mean size of microemulsion droplet formed from Cur-PIP-SMEDDS was 15.33 nm, the drug loading of SMEDDS for Cur and PIP were 40.90 mg · g(-1) and 0.97 mg · g(-1), respectively, the drug entrapment efficiency were 94.98% and 90.96%, respectively. The results show that Cur-PIP-SMEDDS can increase the solubility and stability of curcumin significantly, in the expectation of enhancing the bioavailability of it. Taken together, these findings can provide the reference to a preferable choice of the Cur formulation and contribute to therapeutic application in clinical research.

Objective To explore effect of endogeneous gangliosides(Gls) and integrin ?2?1 on protein phosphotyrosine expression of pp125 focal adhesion kinase (pp125FAK) after adhesion of SK-N-SH neuroblastoma cells to collagen(Col).Methods SK-N-SH cell line with high expression of integrin ?2?1 was cultured in presence of D-threo-1-phenyl-2-decanolamino-3-morphinoline-1-propanol(D-PDMP).Effect of endogeneous Gls,anti-?2 and anti-?1 monoclonal antibody on protein phosphotyrosine expression of pp125FAK during adhesion of SK-N-SH cells to Col were determined by immunoprecipitate and Western blotting.Results After 6 days,endogenous Gls in cells were almost depleted.Gls-depletion,anti?2 and anti-?1 monoclonal antibody were able to decrease pp125FAK expression of SK-N-SH cells adherent to Col respectively.GD2,the major component of neuroblastoma cell Gls could reco-ver pp125FAK expression to a certain degree.Conclusions Endogenous tumor Gls regulate protein phosphotyrosine expression of pp125FAK during adhesion of neuroblastoma cells to Col.It is suggested that tumor Gls may increase signal transduction of tumor cell integrin ?2?1 by increasing tyrosine phosphorylation of pp125FAK.

OBJECTIVE: To investigate the inhibitory effect of compound Daqiqi decoction(CDQD) combined with cisplatin on subcutaneously transplanted ovarian cancer in nude mice and its related mechanisms. METHODS: The 60 subcutaneously transplanted model of nude mice was established with human ovarian cancer cell line SKOV3, and divided into 6 groups randomly, each group of 10 nude mice, which were model group that was treated with saline, CDQD low dose group with the CDQD dosage of 15.16 g•kg-1, CDQD medium dose group with the CDQD dosage of 30.33 g•kg-1, CDQD high dose group with the CDQD dosage of 60.66 g•kg-1, cisplatin group with the DDP dosage of 3 mg•kg-1 and combined group that was treated with the CDQD dosage of 30.33 g•kg-1 and the DDP dosage of 3 mg•kg-1. Cisplatin was administered once every 3 d, and the remaining drugs were administered once a day. Then,the tumor-bearing mouse model was given the corresponding drugs for 14 consecutive days, and the tumor volume was measured every 3 d. After the end of treatment, the tumor was removed and weighed. The morphology of the tumor cells were observed by HE staining. The apoptosis of tumor cells was detected by TUNEL method. The mRNA and protein expression of miR939 and STAT3 and VEGFA and EGFR in tumor tissues were detected by real-time fluorescence quantitative PCR and Western-blot. RESULTS: The tumor volume and the tumor weight of the treated groups were all decreased(P<0.01). Compared with the model group, the tumor volume and tumor weight of the combined group were less than those of the other groups(P<0.01), and the apoptosis rate of the combined group was significantly higher than other groups(P<0.01).The expression of miR939 and STAT3 and VEGFA were down-regulated and the expression of EGFR were up-regulated in the treatment groups. Compared with the model group, the expression of MiR-939, STAT3 and VEGFA were down-regulated and the expression of EGFR was increased in the treatment group. MiR-939, STAT3, VEGFA expression in the combined group was the lowest(P<0.05), and the EGFR expression was highest(P<0.05). CONCLUSION: Studies have shown that CDQD can inhibit ovarian cancer subcutaneously transplanted tumor in nude mice, and its mechanism may be related to inhibition of MiR-939/STAT3 pathway activation, down-regulation of VEGFA, and up-regulation of EGFR expression. The inhibitory effect of CDQD on ovarian cancer tissues has a concentration dependence. And the combination of CDQD and DDP can enhance the anti-tumor effect of DDP and reduce the side effects of DDP on tumor-bearing mice.

There are similarities between magnetotactic bacteria and Acidithiobacillus ferrooxidans (A. ferrooxidans) which isolated from Acid mine drainage(AMD). The weak magnetotaxis of some bioleaching bacteria isolated were found by microscope. A magnetophoresis apparatus was designed based on these weak magnetotaxis and be used to analysis the movement of these strains. The physiological properties of the anear magnetic field strain and removed magnetic field strain which isolated successfully by magnetophoresis apparatus have large difference. The nanometer magnetic particles was extract from the Acidithiobacillus ferrooxidans which purified by spread plate method from AMFS and its main elements are Fe and O by energy spectrum analysis. The results show that A. ferrooxidans have weak magnetotaxis and can be isolated by magnetophoresis. With the development of this new isolating method, the research of magnetotactic bacteria and bioleaching will get more benefit from it.

Abstract: Objective　To investigate the clinical characteristics and diagnosis key points of brain abscess caused by Nocardia asiatica, and provide a clinical basis for diagnosing and treating intracranial infection caused by Nocardia. Methods　A case of pulmonary Nocardia asiatica complicated with brain abscess diagnosed at the Second Affiliated Hospital of Hainan Medical University was selected to analyze the clinical manifestations, cerebrospinal fluid characteristics, pulmonary and cranial imaging features, and treatment plan, and to summarize the diagnosis and treatment experience. Results　The patient was an elderly woman with a history of diabetes, dry cough was the first symptom without fever or headache. At the beginning of the course, it was diagnosed as pulmonary infection and tuberculosis in the local hospital, and received conventional antimicrobial and anti-tuberculosis therapies, but showed no improvement. The patient developed progressive limb weakness, followed by consciousness disorders, and coma. Cerebrospinal fluid (CSF) adenosine deaminase and lactate dehydrogenase were not abnormal, CSF pressure, protein and white blood cells were high, mainly with multiple nuclear cells. CSF glucose and chloride were normal in the early stage of the disease, but decreased significantly in the later stage. Metagenomic analysis of cerebrospinal fluid indicated Nocardia asiatica with a specific sequence number of 537. Lung CT showed exudation, abscess, and cavity in the right lung. Skull MRI scan + enhancement suggested multiple scattered abscesses in both cerebral hemispheres. The abscesses were of different sizes and showed ring enhancement, with extensive surrounding edema, and ventricular compression. After treatment with meropenem, linezolid, and compound sulfamethoxazole tablets, the cerebrospinal fluid recovered, and the lesions in the lungs and intracranial structures improved. Conclusions　Brain abscess caused by Nocardia asiatica is similar to the tuberculous brain in clinical symptoms, cerebrospinal fluid examination, craniocerebral imaging, so we should be alert to the possibility of Nocardia infection in patients with diabetes. At the same time, metagenomic testing of the cerebrospinal fluid can help confirm the diagnosis. The mortality and disability rates of brain abscess caused by Nocardia are high. Early diagnosis and treatment can improve the prognosis.
