Objective To investigate the expression of extracellular matrix metalloproteinase inducer (EMMPRIN) in pancreatic cancer and its relationship with P-glycoprotein (P-gp) and vascular endothelial growth factor (VEGF),and to study its correlation with invasion,metastasis and drug re- sistance.Methods The expressions of EMMPRIN,P-gp and VEGF in 34 cases of pancreatic cancer were detected by immunohistochemistry.The correlation analysis and Chi squared test were been used by SPSS 10.0.Results The positive rates of EMMPRIN,P-gp and VEGF in pancreatic cancer were 61.8%,55.9% and 64.7% respectively.EMMPRIN,P-gp and VEGF were associated with lymph node metastasis (P＜0.05),but not associated with sex,age,size of tumor and degree of differentia- tion (P＞0.05).There were close relationship between EMMPR1N and P-gp,VEGF respectively (r= 0.398,r=0.432,P＜0.05).Conclusions EMMPRIN,P-gp and VEGF were higher expressed in pancreatic cancer.EMMPRIN express was correlated with both P-gp and VEGF.It has indicated that during the progression of pancreatic cancer,there are close relationship between invasion,metastasis and drug resistance,and EMMPRIN may play key role in this process.

AIM:To study the changes of tear film and ocular surface after the coaxial micro incision 2. 2mm and 2. 8mm in the phacoemulsification.
METHODS:Eighty-six patients ( One hundred and six eyes ) from 2014/06 to 2016/01 in our hospital were enrolled. The patients were randomly divided into two groups. Forty-four patients ( Fifty-three eyes) in group A: coaxial 2. 2mm micro- incision phacoemulsification cataract extraction and intraocular lens(IOL) implantation;Forty-two patients ( Fifty-three eyes ) in group B: the conventional coaxial 2. 8mm small incision phacoemulsification cataract extraction and IOL implantation. The break up time ( BUT) , dry eye symptom ( DES) score, Schirmer's I test ( SⅠt ) and lid-wiper epitheliopathy ( LWE ) score were assessed preoperatively and postoperatively.
RESULTS:At 1wk, 1 and 2mo postoperatively, the BUT in two groups decreased after operations, and the BUT of group B was significantly lower than those of group A, the differences were statistically significant ( t = 3. 098, 4.512, 4.329; all P < 0. 05 ). The DES score in two groups increased, the DES score of group B was significantly higher than those of group A and the differences were statistically significant (t=-9. 449, -10. 029, -7. 141; all P<0. 05). The SⅠt in two groups increased after operations, the SⅠt of group B was significantly higher than those of group A and the differences were statistically significant (t=-6. 293, -4. 009, -3. 283; all P<0. 05). The LWE score in two groups increased after operations, the LWE score of group B was significantly higher than those of group A and the differences were statistically significant (t=-6. 542,-5. 125, -3. 632; all P<0. 05). At 6mo postoperatively, compared with the preoperative data, the BUT, DES score, S Ⅰ t and LWE score in group A showed no statistically significant differences (t=0. 659, 1. 276, 0. 548, 0.169; P>0. 05). The BUT, DES score, SⅠt and LWE score in group B showed statistically significant differences (t=-4. 063, 7. 306, 3. 621, 4. 208;all P<0. 05).CONCLUSION:Ocular surface has less damage and tear film has little influence at early stage after the coaxial 2.2mm microincision phacoemulsification, compared with the conventional coaxial 2. 8mm incision phacoemulsification surgery.

Objective To observe the influence of taurine supplementation during early postnatal life on body weight and ultrastructure of islet ? cells in neonatal rats with low birth weight(LBW).Methods LBW neonatal rats were made by feeding 20%(C group) or 10%(R group) protein diet to fetal rats during gestation and lactation.Half of femal rats in group R were given a supplementation with 2.5% taurine drinking water(RT group) only during lactation,while other femal rats freely drunk.At postnatal day 1 and 21,the neonatal rats were weighted and their pancreas were removed.The ultrastructural changes of ? cells were observed by electron microscopy.Results At postnatal 21 days,the body weight of offsprings in group RT was significantly highter than that in group R(P=0.003);and the ultrastructure of ? cells in group RT got more improvement than that in group R.Conclusion Taurine supplementation can improve the growth-catch-up and the ultrastructure of islet ? cells of neonateal rats with LBW.

Objective: Sarcandra glabra was recognized as an important research material attributing to its high medicinal value and economic value. However, little information was known about its genomics and regulatory pathway participating in reproductive development. For the first step to understand the molecular basis and further explore genes which related to metabolism and resistance in S. glabra. Methods: A SMART full-length complementary DNA library from the leaves tissue was constructed and characterized to providing the experimental basis for discovery of functional genes of S. glabra. The assembly expressed sequence tag (EST) data were completed by ABI3730 DNA program. A high quality full-length cDNA library was constructed successfully from S. glabra leaves. Results: The titer of library was 1.14×107 pfu/mL and the average length of inserted fragments was 1 000 bp. A total of 221 clones were sequenced from the cDNA library and obtained 177 EST sequences. The EST sequences were assembled into 151 unigenes including 12 contigs and 119 singletons (79%). EST exhibited significant similarity with known putative functional nucleotide sequences in the GenBank database. These genes were mostly involved in cell development, signal transduction, protein synthesis, transcription, stress tolerance response, energy metabolism based on molecular function of GO annotation. Conclusion: This report constructs a full-length-cDNA library and analyzes the bioinformatics of the related EST sequences, and then offers a reference to genomic research of S. glabra.

Abstract： Objective　To investigate the distribution and antimicrobial resistance profile of the bacterial strains isolated from blood cultures in neonatal septicemia children of Neonatology Department, the First People's Hospital of Chuzhou during Jan. 2017-Dec. 2021, in order to guide clinical rational drug use. Methods　The distribution and the results of antimicrobial susceptibility tests and characteristics of the pathogenic bacteria isolated from blood culture samples in neonatal septicemia children in the First Hospital of Chuzhou from Jan. 2017 to Dec. 2021 were retrospectively analyzed. The results were analyzed with WHONET 5.6 software, according to the Clinical and Laboratory Standards Institute (CLSI) 2021 breakpoints. 　Results　A total of 189 strains were isolated from the 4 538 sample of blood cultures, the positive rate was 4.2%, including 59(31.2%) Gram-negative bacterial strains, 130 (68.8%) Gram-positive bacterial strains. The most frequently isolates were coagulase-negative staphylococci（64.0%), Serratia liquefaciens (15.9%), Escherichia coli (3.2%), Acinetobacter lwoffii (2.6%) and Delftia acidovorans (2.6%). The prevalence of methicillin-resistant isolates was 81.8%(99/121) in coagulase-negative Staphylococci and 25.0%（1/4） in Staphylococcus aureus. No staphylococcal strains were found resistant to vancomycin, quinupristin-dalfopristin or linezolid. The sensitivity of the antibacterial drug monitored by Serratia liquefaciens was 100.0%.Conclusions　Gram-positive bacterial are the main pathogen of neonatal septicemia, and is highly resistant to the common antibacterial drugs. The clinical should choose antibacterial agents reasonably according to drug sensitivity.
