3.The role of galectin-4 in physiology and diseases.
Protein & Cell 2016;7(5):314-324
Galectin-4, a tandem repeat member of the β-galactoside-binding proteins, possesses two carbohydrate-recognition domains (CRD) in a single peptide chain. This lectin is mostly expressed in epithelial cells of the intestinal tract and secreted to the extracellular. The two domains have 40% similarity in amino acid sequence, but distinctly binding to various ligands. Just because the two domains bind to different ligands simultaneously, galectin-4 can be a crosslinker and crucial regulator in a large number of biological processes. Recent evidence shows that galectin-4 plays an important role in lipid raft stabilization, protein apical trafficking, cell adhesion, wound healing, intestinal inflammation, tumor progression, etc. This article reviews the physiological and pathological features of galectin-4 and its important role in such processes.

OBJECTIVETo study the cost of the hypertensive outpatients.
METHODSThe study randomly selected 460 insured patients with hypertension and investigated their cost on each case in the out-patient department through 2002, based on the electronic system of medical insurance.
RESULTSAs a whole, the distribution of hypertensive outpatient expenditure takes on the positively skewed, with the median of 1 567.9 Yuan RMB. With the increase of age, the average expenses in each age group increased accordingly. In the study, the average number of outpatient attendances per patient was 19.5, the average expenses per visit was 115.4 Yuan RMB. In age groups 40 - 49 and 50 - 59, expenses of outpatient in male and female groups are obviously different in 2002 (Wilcoxon W(40 - 49) = 36, P(40 - 49) = 0.037; Wilcoxon W(50 - 59) = 374, P(50 - 59) = 0.023), as well as the number of out-patients (Wilcoxon W(40 - 49) = 52.5, P(40 - 49) = 0.007; Wilcoxon W(50 - 59) = 379, P(50 - 59) = 0.028). When considering the factors of gender and age at one time, the outpatient expenditures in the male group were significantly different between the different age groups (chi(2) = 22.3, P < 0.001), as well as the number of outpatients (chi(2) = 25.4, P < 0.001). In addition, the expenditure of drugs, which took a large proportion of the total expenditure of hypertensive outpatients (about 83.6 percent), was divided into three parts according to the degree of correlation with hypertension: direct expenses related to the with disease, the indirect expenses and the irrespective. The proportions of each part were 19.9 percent, 32.3 percent and 47.8 percent respectively.
CONCLUSIONWhen economic evaluation of community prevention is carried out, the cost and cost-benefit analysis based on the analysis of outpatient expenditure and the proportion of expenses on hypertension should be taken into account. Additionally, to provide appropriate mode of medicare, to impact the behaviors and expenditure of patients, and to provide low-cost but good effective drug are also essential and important factors.

OBJECTIVEThis case-control study was aimed to detect the single nucleotide polymorphisms (SNPs) in JWA promoter region, to assess the effect of SNP on transcriptional activity, and to probe the relationship between SNP and the risk of bladder cancer.
METHODSThe design of one control per case was adopted. The JWA gene promoter region in 155 patients with bladder cancer and in 155 cancer-free controls was amplified by PCR-SSCP technique, and the SNP were confirmed by direct DNA sequencing. The recombinant plasmids of JWA promoter fragment which contain the SNP were constructed as CAT reporter gene and were transfected transiently into NIH 3T3 cells for disclosing whether SNP changes the transcriptional activity of the promoter.
RESULTSA novel SNP -76 G-->C at promoter region of JWA gene was found. The frequencies of the C allele and GC genotype at JWA promoter -76G-->C in bladder cancer group (10.00% and 20.00% respectively) were significantly higher than those in control group (5.16% and 10.32% respectively) (P < 0.05). The transcriptional activity of -76GC allele genotype was significantly down-regulated as compared with that of -76GG allele genotype (P < 0.01). Multivariate logistic regression analysis revealed that JWA polymorphism at promoter -76G-->C is an independent novel risk factor for bladder cancer.
CONCLUSIONThe JWA -76G-->C variant genotype may play an important role in transcription regulation of JWA gene and in the susceptibility to bladder cancer.

OBJECTIVETo summarize the clinical features of idiopathic hypogonadotropic hypogonadism (IHH) diagnosed during childhood, and detect mutations in KAL1 and FGFR1, acting as key clues for diagnoses.
METHODWe collected and analyzed clinical data of 21 cases (including demographic data, chief complaint, history of present illness, family history, physical examination, laboratory tests and imaging studies, etc.) diagnosed with IHH from December 2008 to February 2013. Polymerase chain reaction and gene sequencing was applied to detect mutations on KAL1 and FGFR1. Fifty healthy unrelated individuals were choosen as controls.
RESULTOf 21 patients with IHH, 19 were males and 2 females, they visited us initially from 8-17 years old, with an average of (13.58 ± 2.38) years old. Sixteen cases were KS patients (76%). One boy reported abnormal sense of smelling but having olfactory perfect picture on MRI; 2/19 male cases had no puberty when they were over 13-14 years old without abnormal external genitalia. 8/19 cases only had small penis, 8/19 had both of cryptorchidism and small penis, and the Case 2 also had hypospadias. One boy had cryptorchidism combined with a normal penis. Only 2 girls diagnosed as IHH who visited us because of no puberty signs when they were 13 and 16 years old, respectively. Other clinical manifestations included: one with gynecomastia, 2 had mental retardation, and one was deaf; one with high palatal arch; one with mirror-movement and one with left renal agenesis but normal renal function respectively. Laboratory tests showed that the basic testosterone (T) is low and with inappropriately low or normal gonadotropin hormones. The results of cases of standard human chorionic gonadotropin (HCG) test of 7 cases out of 19 male children's were normal (testosterone>1 100 ng/L), and another nine cases continued to complete the extended HCG test, and the testosterone levels of two of them (cases 6, 8) were still lower than 1 000 ng/L. Family history: the parents in 9/21 family had delayed puberty, involving only one parent in 6 families, involving both in 2 families and the other one was an uncle having micropenis with a child. Among these 21 cases, only one boy's father had hyposmia and his first emission age was 14-15 years. Eleven patients accompanied abnormal sense of smelling and the olfactory organ abnormalities on MRI, 4 had olfactory organ abnormalities on MRI while they had good smelling function self-reportedly. We got 15 samples (12 KS and 3 nIHH cases) to screen the mutation of KAL1 (14 exons) and FGFR1 (18 exons). A splicing mutation c.1062+1G>A in KAL1 is identified in case 17 with IHH. One novel heterozygous FGFR1 mutation, a single base deletion mutation on the exon 1 c.27delC is identified in case 14. This mutation causes the premature termination codons.
CONCLUSIONThis pilot research showed that IHH/KS diagnosis in children depends on clinical manifestation rather than gene analysis. Small penis or cryptorchidism, smelling abnormality and positive familial history may contribute to the KS/HH diagnosis. MRI of olfactory bulb acts as important proof for diagnosis of KS. Mutations in KAL1 and FGFR1 gene are not main causes of Kallmann syndrome.

BACKGROUNDBloodstream infections (BSIs) remain a major cause of morbidity and mortality in patients undergoing surgery. This study aimed at elucidating the clinical characteristics of community-acquired BSIs (CABs) and nosocomial BSIs (nBSIs) in patients admitted to the surgical wards of a teaching hospital in Beijing, China.
METHODSThis cross-sectional study compared 191 episodes of BSIs in 4074 patients admitted to the surgical wards between January 2008 and December 2011. Cases of BSIs were classified as CABs or nBSIs, and the characteristics, relevant treatments, and outcomes of CABs and nBSIs were compared.
RESULTSOf the 191 BSIs, 52 (27.2%) and 139 (72.8%) were CABs and nBSIs, respectively. Escherichia coli, coagulasenegative staphylococci, and Klebsiella spp, were the most frequently isolated microorganisms. There were significant differences between CABs and nBSIs with respect to the use of hormonal drugs, ventilation, acute physiology and chronic health evaluation (APACHE) II and American Society of Anesthesiologists scores, and prevalence of cancer (P < 0.05). Empirical antibacterial therapy did not decrease the crude mortality, but multivariate analysis showed that high APACHE II was independently associated with a risk of mortality (odds ratio = 0.97, 95% confidence interval: 0.93-1.02 for APACHE II).
CONCLUSIONSWe found significant differences in the clinical characteristics of surgical patients with CABs and nBSIs. The outcome of patients seems to be related to high APACHE II scores.

Objective To investigate the prevalence of iron deficiency(ID)and iron deficiency anemia (IDA) in pregnant women in urban areas of China. Methods The study was a national cross-sectional survey conducted from September 19th, 2016 to November 20th, 2016. According to the classification of the National Bureau of Statistics, all survey sites were set up in 6 regions of the country. Pregnant women were continuously selected using multistage stratified sampling. A total of 12 403 pregnant women were collected and examined for serum ferritin and hemoglobin levels. Results The median serum ferritin level during pregnancy was 20.60 μg/L(11.78-36.98 μg/L), the hemoglobin level was(118±12)g/L. With the progress of pregnancy, the levels of serum ferritin and hemoglobin decreased gradually. The median serum ferritin levels in the first, second trimester and third trimester were 54.30 μg/L(34.48-94.01 μg/L), 28.60 μg/L(16.40-50.52 μg/L), and 16.70 μg/L(10.20-27.00 μg/L)respectively(P<0.01). The mean hemoglobin levels were(127 ± 10)g/L,(119 ± 11)g/L and(117 ± 11)g/L respectively(P<0.01). The prevalence of ID in urban pregnant women was 48.16%(5 973/12 403), and IDA prevalence was 13.87% (1 720/12 403). The prevalence of IDA in the first, second trimester and third trimester were 1.96% (20/1 019), 8.40%(293/3 487)and 17.82%(1 407/7 897), respectively(P<0.01). The prevalence of standardized ID and IDA were significantly different in various regions of China(P<0.01). The standardized prevalence of ID were relatively higher in East China and Northeast China, 57.37% and 53.41% respectively, while it was the lowest in Southwest China, 30.51%. The standardized prevalence of IDA in South Central, Northwest, and East China were relatively high, 21.30%, 16.97% and 17.53% respectively, and the standardized prevalence of IDA in Southwest China was the lowest, 5.44%,the differents in various regions were significant(all P<0.01). Conclusion The current phenomenon of ID and IDA in pregnant women is still very common,and nutrition and health care during pregnancy should be strengthened.

To establish HPLC-MS/MS method for simultaneous determination of 14 toxic or active components in Fuzi formula granules, and further analyze the quality consistency of 29 batches of formula granules by considering the cluster analysis (CA), principal component analysis (PCA), and partial least squares discriminant analysis (PLS-DA) and other chemometrics methods. Phenomenonex Gemini C18 column (4.6 mm×150 mm, 5 μm) was used with 0.1% formic acid solution (A) -acetonitrile (B) as the mobile phase. The mass spectrum was scanned by ESI⁺ multiple reaction monitoring (MRM) mode. The contents of aconitine, mesaconitine, hypaconitine, Indaconitine, benzoylaconine, benzoylmesaconine, benzoylhypaconitine, aconine, fuziline, neoline, talatisamine, songorine, higenamine and salsoline were determined. The results showed that 14 compounds had a good linear relationship within their respective concentration range (R²>0.990 0). The limit of quantification was 2.07-7.71 mg·L⁻¹, and the average recovery was 96.07%-102.2%. The content determination results demonstrated that all batches of Fuzi formula granules had very low hypertoxic ingredients and high safety, while the content of active ingredients was greatly different. CA and PCA results showed that there were significant differences in the formula granules between two manufacturers; even though the different batches of samples from the same manufacturer had certain differences, but the difference in manufacturer A was less than that of B. Further PLS-DA showed that the content of cardiotonic substance salsola in the formula granules from manufacturer A was generally higher, while the contents of analgesic and anti-inflammatory substances benzoylmesaconitine and fuziline were generally lower than those in the products from manufacturer B. In conclusion, the safety of Fuzi formula granules was assured well, but the consistency needed to be improved. We recommend that all manufacturers establish strict standard for decoctions in the production process, and form a unified standard method to produce better Fuzi formula granules.
