Chinese Journal of Bases and Clinics in General Surgery 2003;0(03):-
Objective To develop a method of adult porcine pancreatic islet isolation.Methods The tails of adult porcine pancreas were perfused through the pancreatic duct with 0.1% cold collagenase(type Ⅺ) and incubated at 38.5 ℃.The digested tissue was dispersed in 4 ℃ Hanks balanced salt solution(HBSS).The tissue suspensions were filtered through a 600 ?m mesh.The residual tissue was resuspended in cold HBSS,and put in the Ricordi’s chamber and shaken for 5 minutes,then filtered again.The isolated islets were divided into three groups: control group( n =14),Pefabloc(trypsin inhibitor, n =8) group and FOY(trypsin inhibitor, n =5) group.The collagenase solution of the Pefabloc and FOY group was supplemented with 1.0 mmol/L Pefabloc and FOY respectively. Results The islet yields of the Pefabloc group and FOY group 〔(11 848?3 530) islet/g pancreas and (14 496?3 693) islet/g pancreas〕 were significantly higher than that of the control group 〔(8 505?3 349) islet/g pancreas〕, P

China Oncology 2000;0(06):-
Bone metastases in advanced lung cancer patients are common and affect the life quality seriously. So early diagnosis and appropriate treatments are important. The methods of diagnosis include X-ray, CT, MRI, ECT and PET, which are different in sensitivity and specificity. The gene microarray technique is another advance for detecting micrometastasis. The gene analysis also can help understanding the biological characteristics of the primary tumor. The treatment of bone metastases in lung cancer is various, including systemic and local therapeutic means. Surgery is often used to prevent or treat the compressions and bone fractures. Radiotherapy is one of the most effective methods of pain relief. Diphosphonate provides a new convenient and effective way of alleviative treatment. In addition, supportive and symptomatic treatments should be keep in mind.

OBJECTIVE:To provide reference for continuous improvement of drug counseling and pharmaceutical care. METH-ODS:220 cases of drug counseling answered by inpatient general pharmacist were collected from our hospital during 2012-2013, and the contents of drug counseling were classified and analyzed. RESULTS:Among consultants,73.18% of them were physi-cians;the type of drug involved mainly were antibiotics,accounting for 42.73%;main contents of drug counseling included drug selection,usage and dosage,accounting for 47.27%. CONCLUSIONS:Pharmacists provide drug counseling for physicians and nurses,answer various questions about usage,and guide rational drug use so as to enhance the communication between pharma-cists and physicians,nurses,and promote rational drug use in the clinic.
4. Inhibition effects of tea flower extract on glucose absorption in experimental glucose tolerance mice
Journal of International Pharmaceutical Research 2014;41(4):456-460
Objective To study the inhibitory effects of tea flower extract (TFE) on α-glucosidase and glucose intestinal absorption. Methods Three different postprandial hyperglycemia models (2 g/kg glucose, 4 g/kg sucrose, and 6 g/kg starch) were used, with 8 mice in each group. Oral administration of 150 or 300 mg/kg of TFE, 6.25 mg/kg of acarbose, or water was performed on mice 1 day and 30 mins before the oral administration of 2 g/kg glucose, 4 g/kg sucrose, and 6 g/kg starch at 10 ml/kg of body weight. Blood glucose levels were analyzed chronologically to evaluate the effect of TFE. In vitro studies were also performed to study the inhibitory effects of TFE on α-glucosidase and small intestinal mucosa glycosidase.

Objective To construct the bicistronic retroviral vectors containing GFP gene and human survivin gene(wildtype and T34A mutant). Methods Survivin fragments were amplified from eukaryotic expression vectors by PCR, then cloned into pMIG retroviral vectors. The constructed recombinant was identified by double digestion with restriction enzymes. The constructed retroviral vectors was transfected into Phoenix E package cells under mediation of liposome. The expression of mRNA was examined by RT-PCR and the transcription of gene was determined by FACS analysis of GFP. Results The target fragments were successfully bound to pMIG vector. After the vectors were transfected into NIH3T3 cells, the expression of mRNA was confirmed by RT-PCR and the expression of GFP was confirmed by FACS analysis. Conclusion Human survivin gene wildtype and T34A mutant retroviral vectors have been constructed successfully, which can provide strong molecular tools for further studies and a novel approach for selective cancer gene therapy.

Objective To analysis the relationship between the multipathogens infection and unhealthy pregnancy.Methods All patients was selectively divided into three groups:group A including 106 patients with unhealthy pregnancy,group B:55 gravidas with normal induced abortion,group C:55 normal parturient with term labor.The ten kinds of pathogens from abortion tissues and placentas were tested by PCR method respectively.Anti-pathogen IgM antibodies were detected by ELISA in the blood specimens.Results The distribution status of the pathogens were as followed:Human parvovirus B19(B19V 23.6%)>Cytomegalovirus(CMV,16.0%)>Toxoplasma (TOX,15.1%)>Rubella virus(RV,10.4%)>Ureaplasma urealyticum(9.4%)>Coxsackie(7.5%)>Herpes simplex virus(HSV,6.6%)>Adenovirus,Eprstan Barr virus(3.8%)>Chlamydia trachomatic(CT 2.8%) in the group A.The positive rates of the pathogens infection in both group C and group B were lower.The positive rates of B19V,CMV,RV,HSV,TOX were significant difference(χ2 test,P=0.000~P=0.031) among the three groups,hovever others were not(χ2 test,P=0.121~P=0.724).Conclusions The pathogen infection is an important factor to occur the unhealthy pregnancy,the major pathogens of unhealthy pregnancy are B19V,CMV,TOX,RV,HSV.These pathogens infection should be detected timely in gestational period.

OBJECTIVE To evaluate distribution and resistance of pathogens in patients with pulmonary infection after abdominal operation by stages,and provide reference to select antibiotics in clinics.METHODS Forty five patients with pulmonary infection after abdominal operation were included from Jan 2004 to Sep 2007.Their course was divided into 3 stages: onset stage,middle stage and last stage,at every stage to identify pathogens and to test drug sensitivity and the sputa and broncho-alveolar lavage fluid(BALF) were sampled.RESULTS A total of 189 strains of pathogens were isolated,from them 110(58.2%)were Gram-negative bacilli including Pseudomonas aeruginosa,Escherichia coli and Klebsiella pneumoniae;and 59(31.2%)were Gram-positive cocci including Staphylococcus aureus and Enterococcus;and 20(10.6%)were fungi,Candida albicans was the main fungus.At onset stage the most pathogens were Gram-negative bacilli;at middle stage the Gram-positive cocci increased distinctly;and the fungi were detected at middle and last stages.The mixed infection rate was high.The result of drug sensitive test showed that there were high rates of multidrug resistance in P.aeruginosa.The resistance rates of all isolates of Enterobacteriaceae to imipenem or meropenem were 0.The resistance rates of all Gram-positive cocci to linezolid or vancomycin were 0.CONCLUSIONS Distribution of pathogens in patients with pulmonary infection after abdominal operation is different at each stage.The most are multidrug resistant,and rationl use of antibacterial drug in clinics must be based on the distribution and drug-resistance of pathogens.

Irritable bowel syndrome(IBS)is one of the most common functional gastrointestinal disorders,which impacts on patients’quality of life as well as physical and mental health. Studies have shown that visceral hypersensitivity (VHS)is an important pathophysiological factor in the pathogenesis of IBS,and neural regulation plays a key role in the process of VHS. This article reviewed the advances in study on effect of neural regulation pathway on pathogenesis of VHS in IBS.
