Mannose-binding lectin(MBL) is a key component of the innate immune system that plays a pluripotent role in natural defense.MBL genetic variants are associated with increased susceptibility to and the severity and prognosis of various diseases.The association between low MBL-producing allelic variants and disease risk and/or severity is particularly strong in infectious and autoimmune diseases.Enhanced risk for disease by low MBL producers is particularly the case for children and immunocompromised patients,especially when primary and secondary immune deficiencies coexist.Therefore the use of MBL testing and replacement therapy has reached the threshold of personalized medicine.The author presents a review of the role of MBL in health and diseases,the advances in MBL testing methodology and MBL related therapies.

Objective To investigate the effect of bowel preparation before colonoscopy and its influencing factors. Methods A total of 283 patients with colonoscopy were recruited by convenience sampling method. They were investigated with basic information questionnaire of bowel preparation and their intestinal cleanliness were assessed by the Ottawa Assessment Scale. The status of bowel preparation and it′s influenced factors were analyzed. Results The total score of Ottawa Assessment Scale was (5.37 ± 2.22) points, and the efficiency of intestinal cleaning was only 59%(167/283). Logistic regression analysis showed that age (OR=1.033, P=0.013); history of chronic constipation (OR=10.341, P=0.000);history of appendectomy (OR=5.349, P=0.007); walking time during medication (OR=0.350, P=0.000);incomplete intake of the preparation (OR=0.078, P=0.000), the time interval between the initiation of ingestion and the onset of bowel activity (OR=1.034, P=0.000), defecation frequency (OR =0.794, P=0.004);characteristics of last stool (OR=0.159, P=0.000) were influencing factors of intestinal cleanliness. Conclusions The intestinal cleanliness of patients with colonoscopy is still at a low level. In the future, medical personnel should identify patients with risk factors early, and give them specific bowel preparation, so as to improve the quality of bowel preparation effectively.

Objective To investigate the effect of CHRNA1 genetic polymorphism on neuromuscular blockade induced with rocuronium. Methods Ninety-five ASA Ⅰ or Ⅱ patients of both sexes (age 18-64 yr,BMI 18-25 kg/m2 ) undergoing elective intra-abdominal surgery under general anesthesia were divided into 3 groups according to their genotypes: group Ⅰ AA ( n = 71 ); group Ⅱ AG ( n = 19) and group Ⅲ GG ( n = 5). ECG,BP, HR and SpO2 were continuously monitored during anesthesia. Neuromuscular function was assessed by response of adductor pollicis muscle to stimulation of the ulnar nerve using TOF-Watch SX monitor. Genomic DNA was extracted by using proteinase K digestion followed by a salting out prosedure. rs16862847 polymorphisms were analyzed by PCR-restriction fragment length polymorphism analysis and direct sequence analysis. Anesthesia was induced with fentanyl 4 μg/kg and propofol 2 mg/kg. Rocuronium 0.2 mg/kg was injected iv as soon as the patients lost consciousness. Results The twitch height of adductor pollicis muscle was significantly decreased in group AG and GG as compared with group AA ( P ＜ 0.05). There was no significant difference between group AG and GG.Conclusion CHRNA1 genetic polymorphism can influence the neuromuscular blockade induced with rocuronium,indicating that the genetic factor is one of the reasons contributing to the individual variation in neuromuscular blockade induced with muscle relaxants in patients.

Objective To investigate radiation-induced alternations of phospholipids in epithelial cells,and to provide experimental evidence for understanding the mechanism of radiation-induced intestinal injury.Methods The intestinal epithelial cells(IEC-6)in rats were divided into three groups:normal control group,8 Gy X-ray irradiation group and 12 Gy X-ray irradiation group.Phospholipids were extracted at 6 h or 24 h after radiation and then measured by high-performance liquid chromatography and mass spectrometry(HPLC-MS).Results At 6 h after radiation,the phospholipids in 8 Gy irradiation group didn't vary significantly,while those in 12 Gy irradiation group changed.The PG,PI and Lyso PC were significantly up-regulated(F=5.37,9.60,9.88,P＜0.05).However,at 24 h after radiation,many PE and PG species in both irradiation groups declined(F=5.15-99.77,P＜0.05)and SM species increased in 12 Gy irradiation group(F=4.35-7.92,P＜0.05).Conclusions The ionizing radiation could disorder phospholipid metabolism in IEC-6 cells with a dose-dependent manner.

Objective To identify the pathogenic gene for a Chinese Han consanguineous marriage family with autosomal recessive cerebellar ataxia by homozygosity mapping and mutation analysis.Methods Six members of the family were enrolled in this study,including 3 patients,the unaffected sibling and their parents of first cousin marriage.After excluding GAA repeats mutation of FXN gene,whole-genome single nucleotide polymorphism (SNP) microarray scanning and homozygosity mapping were performed to localize the candidate gene.The coding regions and intronic flanking sequences of the candidate genes were analyzed.Results Four candidate regions were identified,including 2p25.3,9q22.2-34.3,13q12.3-14.3 and 17p13.The SETX gene localizing in 9q22.2-34.3 that is responsible for ataxia with oculomotor apraxia 2 was analyzed at first.There were 4 mutations in exon 10,including three missense mutations (c.3576T ＞ G,p.D1192E ; c.3754G ＞ A,p.G1252R; c.4156A ＞ G,p.I1386V) and a deletion mutation (c.5084_5087delAGTC,p.Q1695_S1696del).Three patients were homozygous of the 4 mutations,an unaffected sibling was normal,and their parents were heterozygous of 4 mutations.Conclusions The pathogenic haplotype comprising four mutations of the SETX gene was identified in the consanguinity family.c.5084_5087delAGTC (p.Q1695_S1696del) is a novel mutation.The affected individuals of this family were characterized by mild phenotype and slow progress without oculomotor apraxia,indicating the clinical variability of the disease.

Objective To observe the effects of metformin on expression of Adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK),nuclear factor-κB (NF-κB) and transforming growth factor β1 (TGF-β1) in cultured rat glomerular mesangial cells (MCs),and explore its renoprotective mechanisms.Methods MCs were cultured in the medium with normal glucose (group NG,5.6 mmol/L),high glucose (group HG,25mmol/L) and different concentrations of metformin (group M1,M2,M3).After 48 h exposure,the supernatants and MCs were collected.The expression of NF-κB and TGF-β1 mRNA was analyzed by real time-PCR.Total-AMPK,phospho-Thr-172 AMPK (p-AMPK),NF -κB p65 and TGF-β1 were visualized by Western blot.Results The real time-PCR and Western blot result showed MCs could express AMPK,NF-κB and TGF-β1 mRNA and protein.After stimulated by HG,the levels of intracellular NF-κB and TGF-β1 expressions were significantly increased compared with group NG (P ＜ 0.05); The levels of NF-κB and TGF-β1 were significantly decreased in group M1,M2 and group M3 compared with group HG in a dose-dependent manner.After stimulated by HG,the level of intracellular p-AMPK were down-regulated compared with group NG(all P ＜ 0.05); The expression of p-AMPK increased with the rising of metformin concentration,presenting the opposite trend (P ＜ 0.05),while the level of total-AMPK protein was unchanged with exposure to HG or different concentrations of mefformin(P ＞ 0.05).Conclusion Metformin can suppress the expression of NF-κB and TGF-β1 of glomerular MCs induced by HG via AMPK activation,which may partly contribute to its reno-protection.

Breast cancer is the highest incidence and mortality of malignant tumor in women. Recurrence and distant metastasis are the main cause of death. Zoledronic acid (ZOL) has the potential to inhibit bone resorption characteristics mediated by osteoclast, which not only could suppress tumor cell proliferation and start the apoptosis of tumor cells, but also might interfere the adhesion of cancer cells to bone matrices, thereby could inhibit the migration and invasion of tumor cells. In some preclinical studies zoledronic acid has been demonstrated to have the direct anti-tumor effects on breast cancer. There are different therapeutic effects in treatment with zoledronic acid between the premenopausal and post-menopausal patients with breast cancer. This review summarized basic and clinical research progress of the anti-tumor differentiation effect of zoledronic acid in breast cancer.

ObjectiveTo study the occurrence and influence factors of drug-induced injuries of vital organs caused by traditional Chinese medicine injection.MethodsChina Hospital Knowledge Database (CHKD) from 1993-2013 and case reports concerning adverse effects and drug-induced diseases caused by traditional Chinese medicine injection from Wanfang Data Knowledge Service Platformwere retrieved. Indicator systemwasestablished and relevant contentsweresummarized and analyzed.Results34 types of traditional Chinese medicine injectionswereincluded and 699 drug-induced diseasesweresummarized, taking up 53.98% of the total adverse effects. Among them, the top three included in the drug-induced diseaseswere acanthopanax injection, safflower injection and Mailuoning injection.
