OBJECTIVE:To study invalid medical order warned by Prescription automatic screening system (PASS),and to improve rational drug use monitoring. METHODS:The infusion medical order warned with black light,red light and orange light by PASS were extracted from Pharmacy intravenous admixture services(PIVAS)of our hospital during Oct. to Dec. 2014. Invalid warning items were analyzed statistically in respect of warning level,problem types and reasons. RESULTS & CONCLUSIONS:There are 3 392 warnings items,468 were invalid (13.80%) which include 10 items by black light,219 items by red light and 239 items by orange light;by problem types,there are 218 items of overdose and 136 items of repeated treatment,etc. The main causes of invalid warning include 191 items caused by wrong system prompt,126 items by incomplete system information,143 items by insufficient auditing standards,etc. There are still some defects of invalid warning in practical application of PASS. It is suggested that user and developer add the function of self-defined drug list or user-defined system data by,and unify auditing stan-dards of rational drug use,etc.,so as to timely update the system information,and improve the accuracy of software system moni-toring and warning function.

Objective:To explore the relationship between the polymorphisms in gene FGFR1, FGF10, FGFI8 and the nonsyndromic cleft lip with or without cleft palate (NS CLP) in Chinese population. Methods: Genomic DNA was isolated from peripheral lymphocytes of 75 patients with NS CLP and their parents and 75 unimpaired healthy children. The polymorphisms in FGFRI gene rs13317, p. E467K, p. M3691 and p. S393S, FGF10 gene rs1448037 and FGFI8 gene rs4043716 were detected by applying three-dimensional (3-D) polyacrylamide gel microarray technology. The data were performed using statis-tical analysis : the genotype frequenc+ y and allele frequency between patients with NSCL/P and control subjects were performed. Haplotype relative risk (HRR) , family based association test (FBAT) , and transmission disequilibrium test (TDT) in nuclear family were performed. Results: There were no poly-morphism in FGFR1 gene p. E467K, p. M369I and p. $393S site, the corresponding base was all G. The polymorphisms of rs13317 and rs1448037 were detected and their genotype frequency and allele frequen-cy showed no significant difference between 75 patients with NSCL/P and 75 normal children. TDT, HRR and FBAT were also no significant differences. The genotype frequency of gene FGF18 rs4043716 showed significant difference, but allele frequency were no significant difference. TDT, HRR and FBAT were also no significant difference. Conclusion: Our studies suggest an association between gene FGF18 rs4043716 and the NS CLP in Chinese population, and no association among gene FGFR1 rs13317, p. FA67K, p. M3691, p. S393S and gene FGF10 rs1448037.

In order to get new antibacterial peptide, we designed a hybrid peptide LfcinB(1-15)-Melittin(5-12), composed of 1-15 amino acid residues of bovine Lactoferricin and 5-12 amino acid residues of Melittin. According to the bias of codon utilization of Escherichia coli, We synthesized the gene encoding the hybrid peptide. We inserted the gene between the sites of Nco I and Sal I of pET-32a and obtained the recombinant expression vector for heterologous expression of LfcinB(1-15)-Melittin(5-12) in Escherichia coli. We used Escherichia coli BL21(DE3) as expression host for the recombinant plasmid. After induced by isopropyl-beta-D-thiogalactoside (IPTG) under the optimized conditions, we realized the fusion protein was successfully expressed. The fusion protein was expressed in soluble form and the level was more than 35% of the total proteins. With (His)6 x Tag, the fusion protein was easily purified by His x Bind Purification Kit. After purification, we obtained 35 mg of fusion protein from 1 L of culture medium. At last, we accomplished that the peptide LfcinB(1-15)-Melittin(5-12) was released from the fusion protein cleaved by enterokinase. The recombinant LfcinB(1-15)-Melittin(5-12) showed antimicrobial activity assayed by agar diffusion test. This is the first report on the heterologous expression of the hybrid antibacterial peptide LfcinB(1-15)-Melittin(5-12) in Escherichia coli and also provides basis for next cost-effective expression of other antimicrobial peptides in genetic engineering.

OBJECTIVETo evaluate the value of cone-beam CT (CBCT) in the diagnosis and orientation of supernumerary teeth in the anterior maxilla.

METHODS195 supernumerary teeth in the anterior maxilla of 146 patients were included, which were examined by CBCT. The number, shape, size, 3-dimensional position, growth direction of the supernumeraries and their relationship with the neighboring teeth were analyzed.

RESULTSThe 146 patients aged from 5 to 39, and males were affected more than females in a ratio of 2.95:1. 102 (69.9%) patients had single supernumerary teeth. Of the 195 supernumerary teeth, 126 (64.6%) were near the middle line, 131 (67.2%) were conical, 51 (26.2%) were curved root, 98 (50.3%) were inverted and had a length of (11.97 +/- 2.40) mm. The supernumerary teeth often caused complications.

CONCLUSIONThe position of the supernumerary teeth is varied in the maxilla, and often causes permanent dentition complications. CBCT imaging yields accurate 3-dimensional pictures of supernumerary teeth, local dental and bony structures, which is helpful for diagnosis and orientation of supernumerary teeth.

Objective To identify the candidate genes in the vicinity of a susceptibility locus (urinary albumin 1,UA-1) contributing to the development of albuminuria in type 2 diabetic KK/Ta mice. Methods Total RNA was extracted from the kidneys of KK/Ta (n=3) and BALB/c (n=2) mice at 20 weeks of age.The gene expression profile in kidney was investigated using the Affymetrix Murine Genome U74Av2 array.Competitive RT-PCR was used to confirm the differential expression of syndecan-4 which located in the vicinity of UA-1.Genome DNA was extracted from KK/Ta and BALB/c mice.DNA sequence analysis of the coding and promotor region of syndecan-4 gene was conducted. Results In the vicinity of the susceptibility locus (UA-1)contributing to the development of albuminuria in type 2 diabetic KK/Ta mice,10 candidate genes that showed differential expression were identified.Among them,the gene expression of syndecan-4in KK/Ta kidneys at 20 weeks of age was up-regulated by 26.1 times of age-matched BALB/c kidneys.Sequence analysis revealed two synonymous polymorphisms in the coding region (A93C and T216C) and three polymorphisms in the promoter region (-T263C,-T396C and -G669A) of the syndecan-4 gene.The TATA box was found at 321 bp upstream from the transcription start site,and the T263C polymorphism was located in the binding site of transcription factor Clox.Conclusions Syndecan-4 gene is mapped in the vicinity of the susceptibility locus contributing to the development of albuminuria in type 2 diabetes.The gene expression of syndecan-4 in KK/Ta kidneys is up-regulated than that in age-matched BALB/c kidneys at 20 weeks of age.Thus syndecan-4 may be one of the potential candidate genes responsible for diabetic nephropathy.Sequence differences in the promoter region influence the expression levels of syndecan-4 genes in KK/Ta kidneys.

OBJECTIVETo investigate the value of CT perfusion imaging in differential diagnosis between Borrmann types II( and III( gastric cancer.

METHODSAll the patients were proven as ulcerated gastric cancer by preoperative gastroscopy and underwent CT perfusion scanning with Aquilion ONE 320 spiral CT from October 2013 to June 2014 in The First Affiliated Hospital of Zhengzhou University, including 19 patients as Borrmann type II( gastric cancer and 23 patients as Borrmann type III( gastric cancer by pathology. Lesions were divided into three parts by two tangent lines perpendicular to the gastric wall of the ulcer edge, including proximal part (close to cardia), ulcer part and distal part (close to pylorus). All the perfusion images were analyzed in the Toshiba 4.7 post processing workstation. Blood flow (BF), blood volume (BV), and clearance (CL) were measured according to Patlak-plot mode, and arterial flow (AF) was measured according to Single-input maximum mode. Differences in all the parameters between Borrmann type II( and III( groups were analyzed. Receiver operating characteristic (ROC) curve was used to determine the threshold of perfusion parameters for differentiating Borrmann type II( and III( gastric cancer.

RESULTSThere were no significant differences in AF, BV and BF of ulcer part between the two groups (all P>0.05). While the CL of ulcer part in Borrmann type III( group was (7.17±2.41) L/s, which was significantly higher than (4.82±2.26) L/s in Borrmann type II( group (P=0.00). There were no significant differences for all the parameters at proximal part and distal part between the two types (all P>0.05). According to the ROC curve, area under the curve of CL was 0.78. Taking 0.59 L/s as the threshold of CL value, the corresponding sensitivity and specificity for diagnosing Borrmann type III( were 70% and 80%, respectively.

CONCLUSIONThe CL value has certain diagnostic value in differential diagnosis between Borrmann types II( and III( gastric cancer.

Objective: To explore the effect and mechanism of Sacubitril/Valsartan on myocardial remodeling and cardiac function in rats with myocardial infarction. Methods: The acute myocardial infarction (AMI) rat model was established by ligating anterior descending branch of coronary artery for one week.A total of 60 adult male rats in SPF grade with AMI were randomized into the Sacubitril/Valsartan group and the model group, who were gavaged with Sacubitril/Valsartan (68 mg/kg, once daily, n=30) versus with normal saline once daily(n=30) for 4 weeks.Twenty-four hours after the last treatment, the left ventricular cardiac function was examined by echocardiography, and pathological changes of the left ventricle were observed under light microscope.The degree of myocardial fibrosis was quantitatively analyzed by picric acid-sirius scarlet staining.Myocardial cells and fibroblasts from rat pups of the same species were prepared in vitro and were divided into the control group, AngⅡ group, LBQ657 group, valsartan group and LCZ696 group.³[H]-leucine incorporation and ³[H]-proline incorporation were used to detect the myocardial hypertrophy and fibrosis. Results: There was no significant difference in left ventricular function between the the model group and the Sacubitril/Valsartan group before medication (P>0.05). Four weeks after administration of the medications, end-diastolic diameter of left ventricle and end-systolic volume of left ventricle were lower [(9.73±0.26) mm vs.(10.52±0.21) mm, P<0.05; (0.19±0.03) ml vs.( 0.31±0.02) ml, P<0.01], and the left ventricular ejection fraction was higher [(60.17±2.18)% vs.(47.16±5.14)%, P<0.01] in the Sacubitril/Valsartan group than in the model group.The degree of myocardial cell injury in the infarct area was lower, and the area of myocardial fibrosis in the non-infarct zone and peripheral infarcted zone were less in the Sacubitril/Valsartan group than in the model group [(4.0±0.1)% vs. (6.1±0.8)%, P<0.001; (15.7±0.8)% vs. (23.8±1.2)%, P<0.001].³[H]-proline incorporation in cardiac fibroblasts was lower in the Valsartan group than in the Ang Ⅱ group [(152.77±8.46) CPM vs.(221.87±13.41) CPM, P<0.01].³[H]-leucine incorporation in myocardial cells was lower in the Valsartan group than in the Ang Ⅱ group [(113.47±2.33) CPM vs.(127.65±2.38) CPM, P<0.01].³[H]-leucine incorporation in myocardial cells was lower in LBQ657 group than in the Ang Ⅱ group [(119.78±2.98) CPM vs.(127.65±2.38) CPM, P<0.05], and the combined application of valsartan and LBQ657 can further reduce myocardial hypertrophy and fibrosis (P<0.05). Conclusions Sacubitril/Valsartan can effectively alleviate myocardial remodeling and cardiac dysfunction after myocardial infarction, and the mechanism may be related to reducing AngⅡ-induced myocardial hypertrophy and myocardial fibrosis.
