Objective To observe the efficacy in combination with Hemp seed pill and lactulose oral solution for treating cancer pafients with constipation induced by morphine-type drugs.Methods 62 Cancer patients with constipation induced by morphine-type drugs diagnosed by pathology or cytology were collected from January 2013 to July 2016 in Suzhou BenQ hospital for this study.The patients in study group received both Hemp seed pill and lactulose oral solution, and patients in control group received lactulose oral solution only.After treatment for 3 weeks,some indexes were observed, including outcomes in the overall response rates, Karnofsky score, weight.Results The total effective rate of the study group was higher than the control group(77.4%vs 48.3%, P<0.05), the difference was statistically significant;After treatment,Karnofsky score and the percentage of patients gaining weight in study group were markedly higher than those in control group,the difference was statistically significant(P<0.05).Conclusion Hemp seed pill combined with lactulose oral solution has a good clinical efficacy in treating pafients with constipation induced by morphine-type drugs, and can improve patient's quality of life.

According to the genomic sequence of foreign four PLRV isolates, three pairs of specific primer were designed and synthesized. The cDNA of the ORF2a gene of PLRV-Ch was synthesized by reverse transcription and followed by Polymerase Chain Reaction amplication. The synthesized 3' and 5' cDNA fragment of the PLRV-Ch ORF2a gene were inserted into pUC19 and cloned in E. coli JM109 and were sequenced respectively. The middle cDNA fragment were directly sequenced. The homology of nucleotide sequence of PLRV-Ch compared with PLRV-S (Scotland, UK), PLRV-N(Netherlands), PLRV-A(Australia) and PLRV-C(Canada) were 98.96%, 98.70%, 94.79%, 97.5%, the homology of putative amino acid sequence are 97.97%, 97.97%, 89.69%, 95.94%. In 3' region of ORF2a gene a slippery sequence for-1 frameshift and its downstream "stem-loop" or "pseudoknot" and upstream nucleotide sequence repeats were found. Authors suggested that the nucleotide repeat sequences characteristic for PLRV could form a tight successively folded complementary double stranded regions and hairpins. This structure possibly has something to do with-1 frameshift. The amino acid sequence of C terminus region of 70 kD protein translated by motif IV has a protease characteristic motif and a helicase motif IV. The amino acid sequence of polypeptide translated by ORF2a gene undergoing frameshift has a single-stranded nucleic acid binding protein-like characteristic motif.

AIM: To investigate the early changes of retinal function in diabetic patients detected by multifocal electroretinogram (mfERG).METHODS: The first-order kernel responses of mfERG were recorded from eyes of 33 normal control subjects,63 diabetic patients without retinopathy and 43 diabetic patients with background retinopathy. The response densities and implicit times of N1 and P1 were compared among the control, diabetic patients without retinopathy and diabetic patients with retinopathy.RESULTS: The response densities of N1 and P1 in central 3 rings were reduced significantly in diabetic eyes with and without retinopathy. And the implicit times of N1 and P1 were delayed significantly only in diabetic eyes with retinopathy.CONCLUSION: mfERG can detect the early changes of retinal function quantitatively in diabetic patients. Analysis of response densities and implicit times of N1 and P1 can reflect the progress of local retinal dysfunction in diabetes.

Objective To analyze the clinical speciality of invasive fungal infection(IFI)and provide doctors with clinical evidence for early anti-fungal therapy.Method One hundred and thirty-seven patients with 91 male and 46 female,who suffered from invasive fungal infection in ICU from January.1,2000 to June 30, 2006,were enrolled in this study.The age ranged from 17 to 82 years old.Out of 137 patients with IFI,the percentage of albicans candida,glabirate candida,tropicalis candida and parapsilosis candida were 47.4%, 26.3%,20.4% and 3.6%,reseparately.The sputum,urine,blood and other drainages were collected to perform the fungal examination after three days of admission every three days.Results Of 137 patients,42 of them were complicated with hemorrhage,53 patients with IFI developed candida anthema in the chest,abdomen and extremity.,49 patients suffering from IFI had organ dysfunction.The chest image revealed that infiltration caused by IFI especially occurred in apex of lung in some patients.The pathogen analysis displayed that albicans candidiasis easily developed candida anthema,glabirate candidiasis frequently resulted in organ dysfunction,and tropicalis candida led to hemorrhage in some organs.Conclusions The clinical specialty,of IFI caused by candida included hemorrhage,candida anthema,organ dysfunction,and infiltration in apex of lung.

Objective To investigate the effect of lemon peel extracts(LPE) on the activity of lactate dehydrogenase and sucrase of Streptococcus mutans (Sm). Methods After serial dilution with trypticase soy broth (TSB) medium containing 2% glucose, LPE was used as the experimental group, and TSB without LPE as the control group. Sm was added to each group,which was then cultured for 6,18,24 and 48 hours in the anaerobic tank. The activity of lactate dehydrogenase (LDH) was measured with the method of oxidation of reduction coenzyme I and the pH value of the culture solution was also detected. The activity of the sucrose was determined with the method of coloration of 3,5-dinitrosalicylic acid. Results The activity of LDH, sucraae and the changes of solution pH were decreased with the increase of the concentration of LPE (P ＜ 0. 01 ). The activity of LDH were declined from (0. 8025 ± 0. 0913 ) × 103 U/L to (0. 2099 ±0. 0283) × 103 U/L; the activity of sucrase were declined from ( -0. 0107 ±0. 0003) × 103 U/L to ( -0.0078 ±0.0002) × 103 U/L; the△pH were declined from(2.8067 ±0.0404) to (2.5033 ±0. 0416) (24 h results). The differences were significant between experimental groups and the control group (P ＜ 0. 01 ), and there were also significant differences among experimental groups with different LPE concentration( P ＜0. 01 ). The inhibitory effect of acid generation and lactate dehydrogenas' activity of Sm were positively correlated ( P ＜ 0. 01 ). Conclusions LPE can inhibit the activity of lactate dehydrogenase,sucrase and the acid production capacity of the Sm in a dose dependent manner. The inhibitory effects in logarithmic phase is stronger than that in other phases of growth cycle.

AIMTo establish a sensitive and specific liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the determination of isomeric impurity in raw drug material of cefepime dihydrochloride.

METHODSThe HPLC separation experiments were performed on a reversed phase C18 column, with acetonitrile-10 mmol x L(-1) ammonium acetate (5:95) as mobile phase (a flow rate of 0.8 mL x min(-1)). The analytes were determined by electrospray ionization tandem mass spectrometry in positive mode. The chromatogram and mass spectra of cefepime dihydrocloride and its isomeric impurity were obtained by LC-MS/MS.

RESULTSThe method can be used for the separation and identification of cefepime dihychrocloride and its isomeric impurity, of which the retention times were 15.28 min and 9.18 min, respectively. Based on the MS/MS spectra of their molecular ions, the different fragmentation pathways of cefepime dihydrocloride and its isomeric impurity were compared and proposed.

CONCLUSIONThe method was rapid, sensitive and specific. It can be used for the identification of the isomeric purity in raw drug material of cefepime dihydrochloride.

The paper is to report the development of a high-performance liquid chromatographic/tandem mass spectrometry (HPLC-MS/MS) method for the determination of icaritin (ICT) in rat plasma. After precipitated with acetonitrile from the plasma, ICT was isolated chromatographically on a Dikma C18 column. The mobile phase consisted of acetonitrile-water-acetic acid (72 : 28 : 1.5, v/v/v). Electrospray ionization (ESI) source was applied and operated in the positive ion mode. Multiple reaction monitoring (MRM) mode with the transitions of m/z 387 --> m/z 313 and m/z 331 --> m/z 315 were used to quantify ICT and the internal standard, respectively. The linear calibration curve was obtained in the concentration range of 2.5-1,000 ng x mL(-1). The lower limit of quantification was 2.5 ng x mL(-1). The inter- and intra-day precision (RSD) were less than 9.63%, and the accuracy (relative error) was within +/-7.42%. The method was proved to be suitable for the pharmacokinetics of ICT, which offers advantages of high sensitivity and selectivity.
