To investigate the protective effects and possible mechanism of Mycelium of Hirsutella hepiali Chen et Shen (MHCS) on metabolic syndromes, free fatty acid and MHCS-treated hepatocytes were used for detecting autophagy-related LC3, p62 and lipid accumulation. Moreover, high fat diet fed mice were used to establish metabolic syndromes model. 50-weeks age mice were randomly divided into: control group, model group and MHCS group. At 80-weeks age, 15 mice were randomly chosen from each group separately for examining oral glucose tolerance, serum insulin, insulin-like growth factor 1 (IGF-1), hepatic LC3, p62, p-NF-kappaB p65, NF-kappaB p65, IL-6 and CXCL-8. Moreover, insulin resistance index (IRI) was calculated. Hepatic pathological changes, including vacuoles, lipids accumulation and fibrosis were observed. Remaining mice were fed with diet separately to 110 weeks-age for statistics of mortality. MHCS promoted autophagy of free fatty acid treated hepatocytes. Mice fed with high fat plus MHCS diet exhibited improved oral glucose tolerance, insulin resistance, hepatic pathology, inflammation, mortality and activated autophagy. The protective effects of MHCS against metabolic syndroms might be through the activation of hepatic autophagy.

To investigate the RHD gene profiles of RhD-negative individuals in population of Fujian Province, it was to design fourteen pairs of specific primers to amplify RHD exon 1, 3 approximately 7, 9, 10, hybrid Rh box, RHD 1227A allele, RHC allele, RHc allele, RHE allele and RHe allele. Rh genotypes were detected by PCR-SSP in 104 RhD-negative donors, some samples with or without RHD genes were analysed by the absorption-elution test, and two RhD-negative samples with eight RHD exons detected were analysed by DNA sequencing. The results showed that 61.54% RhD-negative individuals lacked all the eight RHD exons detected (RHD-/RHD-), 25.97% carried the RHD 1227A allele (62.96% of which were the heterozygote of RHD+/RHD-, and 37.04% were the homozygote of RHD+/RHD+), 8.65% carried the RHD-CE (2 approximately 9)-D allele (RHD+/RHD-), and 1.92% carried the RHD 710delC allele (RHD+/RHD-). Though the most cases of RHD gene deletion were found in dce haplotype, six cases of RHD gene deletion were found in dCe (their RH genotypes were dce/dCe) and two in dcE haplotype (their RH genotypes were dce/dcE). And it was not accurate to predict the Rh phenotype by detecting a single RHD exon, however, and more accurate when eight RHD exons and RHD 1227A allele were detected (chi2=24.43, p<0.005). It is concluded that RHD genes in population of Fujian Province are polymorphic and the RHD genotyping is not reliable enough to replace the RhD serotyping in China.

Objective:To explore the mechanisms of Qianlie Jindan Tablets(QLJD)acting on chronic nonbacterial prostatitis(CNP)in rats based on non-targeted urine metabolomics.Methods:According to the body mass index,we equally randomized 30 eight-week-old male SD rats into a blank control,a CNP model control and a QLJD medication group.We established the CNP model in the latter groups and,from the 4th day of modeling,treated the rats in the blank and model control groups intragastrically with nor-mal saline and those in the QLJD medication group with QLJD suspension,qd,for 30 successive days.Then we detected the changes in the metabolites of the rats by ultra-high-performance liquid chromatography-tandem mass spectrometry,and identified the differential metabolites in different groups by multivariate statistical analysis,followed by functional annotation of the differential metabolites.Results:Eight common metabolites were identified by metabolomics analysis,of which 5 were decreased in the CNP model controls and increased in the QLJD medication group,while the other 3 increased in the former and decreased in the latter group.Creatinine and genistein were important differential metabolites,and the arginine and proline metabolic pathways and isoflavone biosynthesis pathways were the main ones for QLJD acting on CNP.Compared with the blank controls,the model controls showed up-regulated arginine and proline metabolic pathways,increased production of creatinine,down-regulated isoflavone biosynthetic pathway and decreased produc-tion of genistein.The above changes in the model controls were all reversed in the QLJD medication group.Conclusion:QLJD acts effectively on CNP in male rats by regulating L-arginine and proline metabolic pathways,as well as the isoflavone biosynthesis pathway and naringenin metabolism.

Limitations of polyacrylamide gel or agarose gel electrophoretic methods in genotyping research affect the interpreting of detection results. In order to develop a simple and reliable method for appraising results of ABO genotyping detection, the microfluidic chip analysis system was established by using microfluidic chip to replace the gel electrophoresis and combining with multiplex-PCR-RFLP technique. 150 blood samples were tested by this microfluidic chip analysis system with multiplex-PCR-RFLP technique to evaluate its stability and accuracy. The results showed that all the testing results were consistent with serologic ABO genotyping results and 1 blood sample with decrease of B antigen caused by CML was identified. In conclusion, the established microfluidic chip analysis system is stable and reliable technique. Application of this technique enables the ABO genotyping results to be more objective and accurate.

The aim of this study was to establish a diagnostic method for ABO genotyping and to investigate the distribution of ABO genotype in Beijing Han population so as to understand the distribution characteristics and regularity of ABO genotype. An ABO genotyping method was established by using multiplex-PCR-RFLP and PCR-SSP techniques, and the ABO allele frequency in Beijing Han population was investigated. The results showed that A102, O1 and B allele were more common genes in Beijing Han individuals. And A102 allele was predominant in the phenotype A group in this population. Three O2 alleles were found and no A201 allele was found while gene frequency investigation was performed. No A101A101, A101O2, A102O2, BO2 and O2O2 in this population were discovered. It is concluded that the primary regularity of ABO allele distribution in Beijing Han population is found through this study. It provides basic reference for further study of ABO types.

OBJECTIVETo evaluate the clinical efficiency and safety of two-micron laser resection of the prostate-tangerine technique (TmLRP-TT) for the treatment of large-volume ( > 70 ml) prostate in patients with benign prostatic hyperplasia (BPH).

METHODSThis retrospective analysis included 80 BPH patients with the prostatic volume larger than 70 ml, all treated by TmLRP-TT. We comparatively analyzed the levels of hemoglobin and serum sodium before and after surgery, recorded intra- and post-operative com- plications, and followed up the patients at 6 and 12 months after operation for International Prostate Symptom Score (IPSS), quality of life (QOL), maximum flow rate (Qmax), and postvoid residual urine volume (PVR).

RESULTSAll the operations were successfully completed. The mean hemoglobin decreased (0.68 +/- 0.43) g/dl intraoperatively, but no apparent reduction was observed in serum sodium. Lower urinary tract symptoms were relieved significantly in all the cases. At 12 months after surgery, IPSS was decreased by 73.89% as compared with the baseline (20.03 +/- 6.9 vs 5.23 +/- 3.59), QOL by 64.55% (4.09 +/- 1.19 vs 1.45 +/- 1.36), and PVR by 79.30% (97.31 +/- 57.90 vs 20.14 +/- 24.20 ml), while Qmax increased by 140.42% ([8.04 +/- 3.62] vs [19.33 +/- 3.28] ml/s). The incidence of complications was low either intraoperatively or during the 12 months after operation.

CONCLUSIONTmLRP-TT is a safe and effective surgical endoscopic approach to the treatment of large-volume prostate in BPH patients.

Objective To optimize antimicrobial use process,ensure the rational use of preoperative antimicrobial prophylaxis during consecutive operations.Methods Antimicrobial use process in a hospital in December 2015 was optimized,6 072 cases of consecutive operations in May-November 2015 were selected as control group,5 832 cases of consecutive operations in December 2015-May 2016 were as trial group,the qualified rate of rational use of antimicrobial agents was compared between two groups,causes for delayed/prior use was analyzed.Results Before and after the optimization of antimicrobial use process,rates of antimicrobial use were 77.16％ and 78.80％ respectively,there was significant difference between two groups(x2 =8.305,P =0.004).After the optimization of antimicrobial use process,rate of antimicrobial use within 0.5-1 hour was significantly higher than that before the optimization (82.36％ vs 41.11％);rate of antimicrobial use ＜0.5 hour before skin incision decreased from 57.11％ before optimization to 4.32％ after optimization;but rate of antimicrobial use ＞1 hour before skin incision increased from 1.78％ to 13.32％.Causes for delay/prior use of antimicrobial agents was due to the lack of effective communication between doctors and nurses,which resulted in circuit nurses' inaccurate assessment on interval of consecutive operations(62.13％),the duration of intubation or puncture was too long for anesthesiologists (13.57％).Conclusion Optimizing antimicrobial use process in consecutive operations can improve prophylactic antimicrobial use rate within 0.5-1 hour,and is helpful for ensuring the efficacy of antimicrobial prophylaxis.

A boy, aged 2 years and 4 months, had a sudden onset of blepharoptosis of the right eyelid, accompanied by the mouth deviated to the right side, drinking cough, nystagmus, and developmental regression. Cranial MRI showed softening lesions formed after infarction of the right dorsolateral medulla oblongata, while head CT angiography showed no imaging of the proximal part of the V4 segment of the right vertebral artery. The child was diagnosed with dorsolateral medulla oblongata syndrome and was treated with gamma globulin to regulate immune function, with mannitol to reduce neuronal edema, with low-molecular-weight heparin sodium to improve local hypercoagulation of occluded blood vessels, with hyperbaric oxygen to improve local ischemia and hypoxia and promote the recovery of brain function, and with neuromuscular electrical stimulation to promote the recovery of neuromuscular function. Before discharge, only mild right ataxia and Horner syndrome remained. This article reports the first case of infantile dorsolateral medulla oblongata syndrome and provides experience for the diagnosis and treatment of the disease.

Objective This study aimed to describe the prevalence of both type 2 diabetes (T2D) and hypertension, and to explore possible risk factors. Methods A Cross-sectional study was conducted in eight towns cluster-sampled randomly from Deqing County, Zhejiang Province. Totally. 29 306 subjects aged≥18 years old were recruited into this survey. Information on general information, life styles, health status and family history of chronic diseases was collected. Physical examinations including height, weight, blood pressure, etc. were done. Fasting plasma glucose was also tested. Results The prevalence of only T2DM, only hypertension and both of them was 3.34%, 28.72%, and 2.01%, respectively. Such prevalence of both reached a peak at the age of 70-79 years old.Family history of diabetes mellitus(OR=4.94, 95% CI:3.24-7.54, P<0.001) and having a spouse(OR=2.17, 95% CI: 1.18-4.00, P=0.013) were possible risk factors of diabetes mellitus, body mass index(BMI)<24 kg/m2(OR=0.48, 95% CI: 0.39-0.59, P<0.001) was the possible protective factor of diabetes mellitus, BMI<24 kg/m2(OR=0.60, 95% CI: 0.56-0.64, P<0.001), completing compulsory education(OR=0.54, 95% CI:0.49-0.59, P<0.001) and exercise(OR=0.77, 95% CI: 0.69-0.86, P<0.001) were protective factors of hypertension, drinking(OR=1.18 , 95% CI: 1.08-1.29, P<0.001) was the possible risk factor of hypertension. BMI<24 kg/m2(OR= 0.26, 95% CI: 0.21-0.31, P<0.001), completing compulsory education(OR=0.50, 95% CI: 0.35-0.72, P<0.001) and drinking tea(OR=0.80, 95% CI:0.64-0.99, P=0.045) were protective factors of these two diseases. Farmers(OR=1.35, 95% CI: 1.04-1.76, P=0.024), family history of diabetes(OR=4.21, 95% CI: 2.71-6.57, P<0.001) and family history of hypertension(OR=1.86, 95% CI: 1.31-2.64, P=0.001) were risk factors for the co occurrence of two diseases. Conclusions The prevalence of diabetes among adults in Deqing County was relatively lower than other places. The prevalence of hypertension was close to the level of other regions. Age, overweight, alcohol consumption, family history of diabetes and hypertension were the risk factors of diabetes and hypertension. Diabetes mellitus was a high-risk group of hypertension. Further means should be taken to strengthen the self-management and treatment of this group. Further intervention action should be taken to promote health and quality of life.

OBJECTIVE: To understand the infection of hepatitis B virus(HBV) in blood donors, and to evaluate the effectiveness and necessity of TMA technology for HBV-DNA screening in blood donors. METHODS: Using the ELISA/NAT model, routine serology test and NAT were performed in the 169 160 donors，including voluntary blood donors and some of donors returned to donor team. For some donors with test positive NAT, nucleic acid identification test was performed. And the HBsAg neutralized and confirmed assay would conduct in blood donors with unilateral HBsAg positive and HBV-DNA negative result. RESULTS: Among 169 160 donation cases-times, the donors of bilateral positive of HBsAg detection was 803, accounted for 0.476%; donors of unilateral positive was 243, accounted for 0.144%. For 40 specimens with HBV-DNA negative, unilateral HBsAg positive, the neutralization and confirmed assay was performed.In result, only 4 specimens were confirmed to be HBsAg positive, the confirmed positive rate was 10%. Among detected 1003 specimens with HBV-DNA positive specimens, both HBsAg and HBV-DNA positive were 739, the consistency rate between 2 kinds of detection was 73.7%. The comparision of positive rate detected by using 3 kinds of reagents showed that there were statistical differences (P＜0.05); moreover, there were statistical difference in positive rate detected by using Murex reagent and In Tec reagent (P＜0.0125). The comparison of detected rate of HBsAg and HBV-DNA during March 2016-February 2017 showed no statistical difference (P＞0.05). Among 60 blood donors with HBsAg and HBV-DNA who has retured to the donor team, 1 donor presented the transformation of HBsAg from negative to positive, suggesting the HBV infection of window period, HBsAg of the other 59 was negative. The detection of HBV-DNA showed that the HBV-DNA in 28 donors was negative, and the HBV-DNA in 31 donors was positive, 1 donor showed HBV-DNA was uncertain. CONCLUSION The routine TMA technology combined with ELISA HBsAg can effectively shorten the window period for detection of HBV infection, effectively detect the occult HBV infection, and reduce the potential risk of hepatitis B spread due to blood transfusion.
