Abstract: This study is to reveal the correlation between CNVs of HMGR, SQS1, beta-AS gene and genuineness of liquorice. Real-time PCR was used to detect the copy number of HMGR, SQS1, beta-AS gene of liquorice. According to the results, the range of the copy number variation of HMGR gene was between 1 and 3, the copy number of SQS1 gene was 1 or 2, and the copy number of beta-AS gene was only 1. On the basis of the copy number of HMGR, SQS1 and beta-AS gene, there were five groups, type A (2 + 1 + 1), type B (1 + 1 + 1), type C (3 + 2 + 1), type D (2 + 2 + 1) and type E (3 + 1 + 1). There were two types, type A and type B, in Hangjinqi of Inner Mongolia, and the ratio of A to B was 1:1.3. There were also two types, type A and type B, in Chifeng of Inner Mongolia, and the ratio of A to B was 3:1. There were four types, type A, type B, type C and type D, in Yanchi of Ningxia province, and the ratio of A to B was 1:5.1. There were three types, type A, type B and type E, in Minqin of Gansu province, and the ratio of A to B was 2:1. So CNVs mainly existed in the liquorice from Ningxia and Gansu provinces. While the genetic background of liquorice from Hangjinqi of Inner Mongolia was stabilized. The results of the experiment proved that the correlation between CNVs and origins was one of the reasons of genuineness of liquorice.

Objective To study the association of MYH9 gene single nucleotide polymorphism (SNP) with clinical manifestation,pathology and prognosis of IgA nephropathy (IgAN) patients of Han nationality population in Inner Mongolia Autonomous Region.Method One hundred and forty-eight IgAN patients proven by biopsy were enrolled in the study.Fifty-six patients were followed up for 1-97 months.DNA was extracted from the peripheral blood of above patients.PCR restriction fragment length polymorphism (RFLP) assay was used to detect the single nucleotide polymorphisms of MYH9 gene Rs3752462,Rs4821480 sites.Association of different genotypes with clinical features,pathology and prognosis im patients with IgA nephropathy was examined.Result (1) Rs3752462 site was consistent with Hardy-Weinberg equilibrium,while Rs4821480 site did not meet the Hardy-Weinberg equilibrium.(2) IgAN patients with MYH9 gene Rs3752462 site TF genotype had lower systolic blood pressure as compared to those with CC +CT genotype (P＜0.05).There were significant differences in systolic blood pressure,diastolic blood pressure and age between patients with Rs4821480 site GG genotype and patients with TT or GT genotype (P＜0.05).There were no significant differences in Scr,Ccr,plasma albumin,hemoglobin,microscopic hematuria,proteinuria,pathological HASS classification,pathological lesion among Rs4821480 site GG,TT,GT genotypes.(3) Kaplan-Meier survival analysis revealed the time from renal biopsy to renal function decline was shorted in patients with Rs3752462 site CC genotype and Rs4821480 site TT genotype.Conclusions C allele of MYH9 gene Rs3752462 site is an independent risk factor of high blood pressure damage in IgAN patients.Polymorphism of 3 genotypes of MYH9 gene Rs4821480 site is associated to the prognosis of patients.Carrying Rs3752462 site C allele and Rs4821480 site T allele may affect the prognosis of patients.

The present study was to estimate pharmacokinetic parameters of metformin hydrochloride in 20 Chinese healthy volunteers with a limited sampling strategy (LSS), which will provide scientific data for bioequivalence and clinical application. A single dose of metformin was administrated to 20 healthy volunteers. The concentration of metformin in whole blood was determined by validated high performance liquid chromatography (HPLC) method. Multi-linear regression analysis was performed to establish a model to estimate AUC(0-24 h) and Cmax of metformin by LSS method. The LSS models were validated by the Jackknife method. The result indicated: the linearity relationship between AUC(0-24 h) or Cmax and single concentration point was poor. Several models for metformin AUC(0-24 h) or Cmax, estimation were better (r2 > 0.9, P < 0.05). Validation tests indicated that most informative sampling points (C2, C6 for AUC(0-24 h), C1.5, C2 for Cmax) provided accurate estimations of these parameters. So, a multi-linear regression model for estimation pharmacokinetic parameters of metformin by using LSS method is feasible.

Objective To investigate the gastrointestinal symptoms in patients with chronic obstructive pulmonary disease (COPD) and explore its possible reasons.Methods Thirty-six patients with stable COPD were divided into mild group [21 cases,forced expiratory volume in first second (FEV1) measured values/predictive values ≥50％] and severe group (15 cases,FEV1 measured values/predictive values ＜ 50％) according to the pulmonary function.Replacement of 19 healthy volunteers as control group.The patients and volunteers completed the Gastrointestinal Symptom Rating Scales (GSRS) scores and received electrogastrography,the plasma vasoactive intestinal peptide (VIP) and intestinal fatty acid binding protein (Ⅰ-FABP) were detected.Results The GSRS scores in severe group and mild group was higher than that in control group[(17.73 ± 4.64),(14.29 ± 5.44) scores vs.(8.00 ± 2.29) scores],and severe group was higher than that in mild group,there was significant difference (P ＜ 0.05).The percentage of normal slow waves of fasting and postprandial,the percentage of bradygastria in severe group and mild group were lower than those in control group,there were significant differences(P ＜ 0.05).The level of VIP in severe group was lower than that in mild group and control group [(36.07 ± 9.22) μ g/L vs.(44.16 ± 7.88),(46.53 ± 4.54) μ g/L],the level of I-FABP was higher than that in mild group and control group [(35.80 ± 11.69) μ g/L vs.(27.40 ±9.53),(23.58 ±8.18) μg/L],there was significant difference (P ＜0.05),but there was no significant difference between mild group and control group (P ＞ 0.05).Conclusion The patients with COPD are accompanied with serious gastrointestinal symptoms and gastric dysrhythmia,severe COPD can be associated with VIP decrease and Ⅰ-FABP rise in peripheral blood.

Objective To explore the association between polymorphisms in non-muscle myosin heavy chain 9 gene (MYH9) and hypertension susceptibility in chronic kidney disease (CKD)patients.Methods Five hundred and ninety-five persons,including 301 patients with CKD and 294 healthy controls,were enrolled in the study.Two single nucleotide polymorphisms (SNPs) (rs3752462,rs4821480) were genotyped by TaqMan assay or a restriction fragment length polymorphism assay for a further case-control study.The discrepancies of the patients'quantitive traits (including age,sex,systolic and diastolic blood pressure,frequency of different primary diseases and using different kinds of antihypertensive drugs) among different genotypes of the two MYH9 SNPs were analyzed.Meanwhile,the association between polymorphisms in MYH9 and hypertension susceptibility in CKD patients were analyzed in the rs3752462 site.Results The systolic blood pressure of CT genotype patients [(147.94± 27.40) mm Hg] was significantly higher than that of C C genotype patients [(136.43 ± 19.09)mm Hg] by single factor analysis of variance (P ＜ 0.05).The frequency of using all kinds of antihypertensive drugs for CC genotype patients (7.4％) was lower than that of TT (43.9％) and CT (48.7％) genotype patients (P ＜ 0.05).After correcting the age factor,the result of Logistic regression analysis showed that CC genotype was a protective factor of systolic blood pressure increasing.The probability of high blood pressure for CT genotype patients with CKD was 0.175 times than that of CC genotype (95％ CI 0.071,0.431).Conclusions The CKD patients who carry the rs3752462 site CC genotype of MYH9 gene are not prone to high blood pressure.Polymorphism of MYH9 gene rs3752462 site is associated with systolic blood pressure in CKD patients.It may indicate that allele C mutation for T can lead to the increase in systolic blood pressure.

Objective To investigate the changes of plasma microRNA-223(miR-223) and HMGB-1 in pediatric sepsis patients.Methods There were 49 children with sepsis enrolled in the study (sepsis group),severe sepsis group (n=25) and general group (n=24). Meanwhile, 50 healthy children (normal control group) were selected as control group. The expression levels of plasma miR-223and HMGB-1 (high mobility group box 1) were detected. The predictive values of miR-223and HMGB-1 in plasma of children with sepsis were evaluated by receiver operatingcharacteristic (ROC) curve.Results The plasma miR-223 and HMGB-1 expression levels in severe sepsis group and general group were up-regulated compared with those in the normal control group (F=63.02, 76.32,P<0.05). The area under ROC curve of miR-223,HMGB-1 predicting sepsis were 0.904 (95%CI 0.821-0.998), 0.748 (95%CI: 0.625-0.903). There was positive correlation between miR-223 and HMGB-1 (r=3.532, P<0.05). Conclusions The expression levels of plasma miR-223 in children with sepsis are signiifcantly up-regulated, which can be used as early diagnostic markers to relfect the severity of inlfammation in some degree.

Objective To evaluate the therapeutic effect of esophageal intraluminal stents with 125I seeds based on survival time and quality of life (QOL) of patients with advanced esophageal cancer.Methods A total of 37 patients with advanced esophageal cancer who underwent placement of esophageal 125I irradiation stent were followed up.The QOL was evaluated by QLQ-C30 and QLQ-OES18 questionnaires before the procedure, and 1 week and 3 months after.Results The mean survival time of 37 patients was 28 weeks, with 3-month and 6-month survival rates at 94.6% (35/37) and 51.4% (19/37), respectively.Compared with the baseline, the scores of emotional functioning(EF), cognitive functioning(CF),global quality of life(QL), fatigue(FA), pain(PA), financial difficulties(FI) and pain of QLQ-OES18(OESPA) assessed 1 week after stent placement increased (P<0.05) significantly and dysphapia of QLQ-OES18(OESDYS), eating of QLQ-OES18(OESEAT), trouble swallowing saliva of QLQ-OES18(OESSV) and choked when swallowing of QLQ-OES18(OESCH) decreased significantly (P<0.05).At 3 months after stent placement, the scores of FI increased significantly (P<0.05), and those of nausea or vomiting (NV), OESDYS,OESEAT, OESSV and OESCH decreased significantly (P<0.05).The scores of FI,OESDYS, OESCH, role functioning(RF), EF,CF,FA and OESPA at 3 months were significantly different from those at 1 week after the procedure (P<0.05).Other variables at 1 week and 3 months after the procedure were not different from those before (P>0.05).Conclusion Implantation of 125I seeds combined with esophageal intraluminal stents may prolong survival time and improve QOL of patients with advanced esophageal cancer.

Objective To determine the effectiveness and medical cost-effectiveness of clinical rehabilitation for promoting the functional recovery of sub-acute cerebral infarction patients.Methods Totally 247 sub-acute patients with cerebral infarction were randomly divided into a clinical rehabilitation group of 129 and a routine rehabilitation group of 118.The clinical group received a standardized rehabilitation intervention and drug treatment,while the routine rehabilitation group received routine rehabilitation therapy and drug treatment.The Fugl-Meyer assessment (FMA) and the modified Barthel index (MBI) were used to compare the two groups after the treatment and 3 and 6 weeks later.The hospital cost for six weeks was also compared between the 2 groups.Results At 3 and 6 weeks,improvement in the average FMA and MBI scores was observed in both groups but the inter-group differences were not significant.The total hospital cost of the clinical group was,however,significantly less than that of the others.Conclusion Clinical rehabilitation can improve the motor function and ability in the activities of daily living of stroke patients.It also has economic benefits.

Objective To observe the impact of improving the compliance of ventilator bundle on morbidity of ventilator-associated pneumonia (VAP) in intensive care unit (ICU) patients undergoing mechanical ventilation (MV) guided by context of Joint Commission International (JCI) settings, and to study the oral care efficacy of suction tube sponge brush. Methods A prospective study was conducted. The patients who needed MV admitted to Department of Critical Care Medicine of the First Affiliated Hospital of Xiamen University from January 2013 to December 2016 were enrolled. In the context of JCI settings, necessary measurements were taken to enhance the compliance of ventilator bundle each year. In 2013, the preventive measures were set up and the education was strengthened. In 2014,the compliance of hand hygiene and bedside elevation was strengthened. In 2015, a control study was conducted to evaluate the effect between the traditional cotton dipped in chlorhexidine and the suction tube sponge brush rinsed with chlorhexidine on oral health impact parameters. The suction tube sponge brush rinsed with chlorhexidine oral care was introduced to improve compliance. In 2016, electronic bundle checklist for daily self-audits was conducted. The annually morbidity of VAP through the software of hospital and ICU was collected and calculated. The annual incidence of VAP was indicated by the VAP cases per 1000 MV days. Based on the VAP incidence rate in 2013 as 1, the VAP incidence-rate ratio (IRR) of each year was calculated. Results During the study period, a total of 2733 patients admitted to the ICU, including 1403 patients undergoing MV. Ninety-four of the 1403 patients with community-acquired pneumonia (CAP), aspiration pneumonia, back elevation ban, incomplete information, and withdrew from the study were excluded. 1399 patients undergoing MV were enrolled in the final analysis, with total MV days of 11012 days, and 94 patients occurred VAP. The annual incidence of VAP was progressively declined from 2013 to 2016, and the VAP cases per 1000 MV days were 17.0, 10.0, 5.9, 3.5 cases, respectively. Based on the VAP incidence rate in 2013, the IRR of VAP from 2014 to 2016 was also progressively declined, which was 0.59 [95% confidence interval (95%CI) = 0.35-0.98], 0.35 (95%CI = 0.18-0.64), and 0.21 (95%CI = 0.09-0.41), with statistical significance (all P < 0.05). In 2013, ICU patients had the lowest rates of bedside elevation and hand hygiene compliance, which were 28.57% and 54.29%, respectively. Compared with 2013, by the implementation of two quality control circle (QCC) projects for bedside elevation and hand hygiene, the rates of bedside elevation and hand hygiene compliance were improved significantly in 2014, which were 82.35%, 91.18%, respectively (both P < 0.05). In 2015, the compliance of chlorhexidine oral care which was the worst performed in 2014 had been improved by the method of QCC, and the rate of the compliance was significantly higher than that in 2013 (87.10% vs. 62.86%, P < 0.05). Compared with 2013, bundle compliance was significantly increased in 2016, except for the sterile operation of the suction tube [daily wake and weaning: 95.00% vs. 71.43%, bedside elevation for over 30°: 92.50% vs. 28.57%, hand hygiene: 97.50% vs. 54.29%, chlorhexidine mouth care once per 6-8 hours:95.00% vs. 62.86%, turned back and posture drainage: 97.50% vs. 80.00%], the differences were statistically significant (all P < 0.05). The incidences of bad breath, dirt residue and plaque were significantly lower in the group of oral care by using suction tube sponge brush with chlorhexidine (30 cases) compared with the group of traditional cotton pad with chlorhexidine (30 cases; bad breath: 10.0% vs. 40.0% %, dirt residue: 16.7% vs. 70.0%, plaque: 3.3% vs. 30.0%, all P < 0.05). There was no significant difference in the incidence of oral ulcers between the oral brush group and the traditional group (10.0% vs. 30.0%, P > 0.05). Conclusion Ventilator bundle can effectively reduce the morbidity of VAP in the context of JCI settings, and the oral care by using suction tube sponge brush and chlorhexidine can effectively improve oral hygiene.
