3.Mannose-binding lectin: From bench to personalized medicine
Journal of Medical Postgraduates 2003;0(05):-
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 observe the clinical effects and safety of Angongniuhuang Pill (a traditional Chinese medical preparation)adjuvant to haloperidol for the treatment of Intensive Care Unit (ICU)patients in postoperative delirium.Methods A prospective study of 243 postoperative patients with delirium adimitted in Intensive Care Unit of Xinjiang Medical University First Affiliated Hospital (January 2013-December 2014),by using confusion assessment method of Intensive Care Unit (CAMICU).All of 243 patients with delirium were randomly divided into two groups by computer randomization software (SAS 9.1):group A in which patients were treated with Angongniuhuang Pill adjuvant to haloperidol and group Fin which patiets were treated with haloperidol alone.The end of two intervention methods was determined by two consecutive CAMICU showing negative or the treatment were ended up at seven days treatment.The data of general information,and the results of treatment were recorded and analized by statistical software SPSS 19.0.The measurement data was expressed as mean ±standard deviation;the comparision between two groups was tested by t test;and repeated measurement was analised by variance.Count data was described as number and constitution ratio;and intergroup comparision was tested by Chi-square test. Results There was no significant difference in general information between two groups.The delirium duration and ICU treatment time in group A were shorter than those in group F [(3.0 ±0.9)d vs.(3.8 ±1.0) d,P =0.010; (6.2 ± 1.4) d vs.(6.7 ± 1.5) d,P = 0.008].When delirium was diagnosed (T0),all patients had EEG abnormalities.As treatment went on,EEG abnormal rate gradually declined.At day one (T1),there was no statistically significant difference in EEG findings between group A and group F (95.7% vs.97.5%,P = 0.045 ).At day two (T2 )and day three (T3 ),there was statistically significant difference in EEG findings between group A and group F (65.5% vs.77.7%,P =0.038;42.2% vs.56.2%,P = 0.032).The levels of S100βprotein,interleukin-6 (IL-6),tumor necrosis factor α(TNF-α)in two groups at T0 were all elevated without noticeable difference.These markers were all deceased at T1,T2,T3,but the speed of descend in group A was relatively faster than that in group F.The differences were statistically significant (S100β:time effect P <0.01,inter-group effectp =0.002,interaction effectp =0.686;IL-6:time effect P <0.01,inter-group effectp =0.034,interaction effectp =0.01;TNF-α:time effect P <0.01,inter-group effectp =0.003,interaction effectp =0.516). The discharge rate in group A after improvement of general condition was higher than that in group F (89.7% vs.79.3%,P =0.029).The incidence of postoperative complications and mortality 28 days after operation in group A were lower than those in group F (45.7% vs.58.7%P =0.045;12.9% vs. 24.0%,P =0.028).Conclusion During the treatment of delirium,Angongniuhuang pill adjuvant to haloperidol was a better method compared with using haloperidol alone in respect of effectiveness and safety perspectives.It may be a novel approach to the treatment for delirium by the combination of Chinese and Western medicine.

Objective To investigate the inheritance principle of the expanded GAG repeat allele and the clinical features of spinocerebellar ataxias 3 (SCA3) in a consanguinity family with first cousin marriage.Methods The CAG repeats of SCA3 gene were amplified by means of polymerase chain reaction.Fragment analysis with laser-induced fluorescence in capillary electrophoresis were performed for the positive samples detected by agarose gel electrophoresis.Furthermore,the clinical features were analyzed carefully.Results Fragment analysis revealed that the proband carried 2 alleles with 56 and 72 CAG repeats separately.The proband' s father carried 28 and 66,and the expanded CAG repeat allele inherited from his grandfather.The proband' s mother carried 33 and 56,and the expanded CAG repeat allele inherited from his grandmother.The proband' s son carried 27 and 85 and presented with dystonia besides ataxia.Conclusions The proband' s parents have the common ancestors.Their alleles with expanded CAG repeats probably come from the same allele of their ancestor.The GAG repeat is more unstable in the paternal inheritance than in the maternal inheritance.The 71-year-old asymptomatic family member carry the allele with 56 CAG repeats,which indicates the 56 CAG repeats may be not associated with the disease.The patients within this family have variable clinical features,especially the juvenile-onset case presents with apparent dystonia.

Objective To determine the dynamic change of serum procalcitonin (PCT) level after traumatic brain injury and the rclated clinical significance.Methods Serum levels of PCT and adrenocorticotropic hormone (ATCH) in 137 patients with traumatic brain injury and 20 normal volunteers were measured by electrochemiluminescence assay.Correlation between serum PCT level and severity of traumatic brain injury was evaluated.Results Percentage of serum PCT level at low inflammatory-risk threshold detected from day 1 to day 14 after admission was descended from 80.3% to 63.5%.Meanwhile,the percentage of serum PCT level at high inflammatory-risk threshold was a rising-fall-rising trend,but the percentages of serum PCT level at median and definite inflammatory-risk thresholds showed sustained increase from 13.9% to 27.0% and 0.7% to 3.7% separately.Based on the Glasgow Coma Scale (GCS),the dynamic change of serum PCT level demonstrated a distinct bimodal pattern in severe injury group,a gradual falling after rising mode in middle injury group which was significantly and positively correlated with GCS (r =0.463,P < 0.05),and a rising-falling-slight rising tendency in minorinjury group.In addition,the GCS in each group only closely related to the positive detections of serum PCT level detected at days 3 and 7 (x2 =10.32,16.31 respectively P < 0.01).Serum ATCH level at day 1 was far higher than that at day 14 in severe injury group and was significantly higher in severe injurygroup compared with minor and middle injury groups (P < 0.01 or 0.05).Conclusions Positive serum PCT may be predictive of the traumatic brain injury and injury degree within 3-7 days after the injury.The dynamic change of serum PCT is associated with the specialized mechanism of traumatic brain injury and neuronendocrine response,and it may be a useful parameter to assess posttraumatic stress response and prognosis.
