Objectives To investigate the epidemiological and clinical characteristics of dyslipidemia as well as its treatment and influence on accompanying diseases in impaired glucose status among inpatients. Methods A cross-sectional survey was conducted among the inpatients registered in ten university hospitals of Guangdong, China during the week before the Diabetes Day in 2004. The fasting blood glucose (FBG), lipid profiles, BMI, waist to hip ratio (WHR) and concomitant disorders of the first screen during the hospitalization period were recorded. Those who had FBG level from 5.6 to 6. 9 mmol/L and not been previously diagnosed diabetes (PDM) underwent oral glucose tolerance test (OGTF). Results Of the 8753 inpatients investigated, 1067 eases had complete medical records(CMR case) including PDM cases and previously non-diagnosed diabetes ones with FBG ≥ 5. 6 mmol/L. Of the previously non-diagnosed diabetes cases with FBG levels from 5.6 to 6.9 mmmol/L, 65.8% accepted OGTT. Of the CMR cases, 41.9% had PDM, 21.7% was newly diagnosed diabetes mellitus (NDM), 29. 1% had impaired glucose regulation (IGR) and only 7.3% had normal glucose tolerance (NGT). The TG levels in NDM and PDM group were higher than those in IGR and NGT group (P < 0.05, respectively). The HDL-C levels in IGR, NDM and PDM group were lower than those in NGT group (P < 0.05, respectively). Sixty-nine point six percent of the diabetes mellitus (DM) inpatients was accompanied with dyslipidemia and the rate was higher than those in NGT (56.4%) and IGR inpatients (52.5%, P <0.05, respectively). Only 22. 8% of the PDM inpatients underwent treatment of dyslipidaemia and just 3.4% achieved the target suggested by the guideline of ATP-Ⅲ. BMI was higher and waistline longer in the PDM and NDM inpatients than those in the NGT cases (P <0.05, respectively). Seventy-two point eight percent of the PDM inpatients was complicated with more than one type of vascular diseases. Nine point seven percent and 0. 2% of the NDM inpatients were tormented by diabetic nephropathy and diabetic retinopathy respectively. Conclusions More inpatients with accompany DM or IGR had concomitant dyslipidemia than those with NGT, which included hypertriglyccridemia, hypo-high-density lipoproteinemia and metabolic syndrome. Concomitant vascular diseases were more frequently found in PDM inpatients than in the others. Some of the NDM and IGT inpatients were complicated with microvascular diseases.

Increasing lines of evidence has been accumulated that nitric oxide (NO) and nitric oxide synthase (NOS) distribute plentifully in the rostral ventrolateral medulla (RVLM) and contribute to cardiovascular regulation. In the present study, the expressions of neuronal and inducible isoform of NOS (nNOS and iNOS) were observed in the RVLM of acute myocardial ischemia (AMI) Wistar rats experienced electroacupuncture (EA) treatment, thereby the cardiovascular effects of NO in the RVLM were investigated and the mechanism of acupuncture effect on AMI was inferred. The results indicated that in the AMI rats, cardiac functions were markedly attenuated with high serum level of brain natriuretic peptide (BNP) and norepinephine (NE), the number of nNOS-immunoreactive cells and nNOS mRNA exprossion in the RVLM area were increased, while those of iNOS were lowered. EA at "Neiguan" acupoints (Pe 6) 30 min daily for successive 5 d resulted in an improvement of the cardiac functions, decreases in NE and BNP levels; it also increased the expression of iNOS and decreased the expression of nNOS in the RVLM. These results suggest that the curative effect of acupuncture on AMI is possibly attributable to the differential regulation of NOS/NO in the RVLM, leading to decreased sympathetic outflow and improvement of cardiac functions.

OBJECTIVE: To investigate the incidence of neonatal asphyxia and possible contributing factors for the development of severe asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture, China. METHODS: A total of 16 hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture were selected as research centers. A retrospective analysis was performed for the clinical data of 22 294 live births in these 16 hospitals from January to December, 2016 to investigate the incidence rate of neonatal asphyxia and possible contributing factors for the development of severe asphyxia. RESULTS: Of the 22 294 neonates born alive, 733 (3.29%) were diagnosed with neonatal asphyxia, among whom 627 had mild asphyxia and 106 had severe asphyxia. The neonates with low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight had a higher incidence of severe asphyxia (P<0.05). CONCLUSIONS The incidence rate of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture is higher. Low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight may be related to the development of severe neonatal asphyxia.

OBJECTIVEGlycogen debranching enzyme (AGL) plays an important role in complete degradation of the glycogen, and has two independent catalytic activities, i.e., those of alpha-1, 4-glucanotransferase (EC 2.4. 1.25) and amylo-1,6-glucosidase (EC 3.2. 1.33). A deficiency in activities of AGL causes excessive accumulation of glycogen with short branched outer chains and results in glycogen storage disease type III (GSD III; MIM #232 400), an autosomal recessive inborn disorder of glycogen metabolism. The present study aimed to investigate the mutation of AGL in 10 Chinese patients with GSD III.

METHODClinical and laboratory data of 10 patients with typical clinical manifestations of GSD III suggesting hypoglycemia, hyperlipidemia, increased creatine-phosphokinase and its isozyme were collected. The coding regions and their flanking introns of AGL gene of the 10 patients were amplified by PCR and analyzed by direct DNA sequencing. All the mutated alleles were confirmed by bidirectional DNA sequencing. The 3 novel splicing mutations were analyzed by restriction fragment length polymorphism (RFLP) in 50 healthy children (control). The 2 small deletions (c.408-411delTTTG, c.2717-2721delAGATC) were analyzed by fluorescent polymerase chain reaction and gene scan analysis to confirm the number of deleted bases.

RESULTThirteen different mutations were identified, including 4 splicing mutations (IVS6 + 1G > A, IVS6-1G > A, IVS14 + 1G > T, IVS26-2A > C), 5 nonsense mutations (R469X, R864X, S929X, R977X, Y1428X), 3 small deletions (c.408-411delTTTG, c.2717-2721delAGATC, c.2823delT) and 1 insert mutation (c.4234insT). Except for IVS14 + 1G > T, R864X, and R977X, the other 10 mutations are novel; 18 mutated alleles were identified in the 20 alleles (90%). IVS14 + 1G > T was the most frequently seen mutation, accounting for 5 of 20 (25%) alleles examined. None of homozygote and heterozygote of the 3 novel splicing mutations was found in the 50 healthy controls by RFLP analysis. With the fluorescent polymerase chain reaction and gene scan analysis, c.408411deTTTG mutation and c.2717-2721delAGATC mutation were confirmed to have 4 and 5 bases deletion respectively.

CONCLUSIONThirteen mutations were identified in the 10 cases with GSD III, with 10 novel mutations. IVS14 + 1G > T was a relatively common mutation. This study revealed the heterozygosity of AGL gene in Chinese patients with GSD III.

Objective: To observe the clinical efficacy of addition and subtraction therapy of Xuanshen Ganju Tang combined with Sanniutang to post infection cough (PIC) with lung injury caused by dryness and heat, and investigate its effects on allergic inflammation and neurogenic inflammatory mediators.Method: One hundred and eighty eligible patients with PIC were randomly divided into control group (58 cases) and observation group (122 cases) according to the visiting sequence. Patients in control group got compound methoxyphenamine capsules, 2 capsules/time and tid. Patients in observation group got addition and subtraction therapy of Xuanshen Ganju Tang,combined with Sanniutang, 1 dose/day. The treatment course was 7 days in both groups. Symptom scores for cough (day and night), visual analogue scale of coughing (VAS) and scores for lung injury caused by dryness and heat injury were graded. Time to relieve a cough, time to relieve symptoms, time to vanish cough, and cough recurrence were recorded. Life quality was evaluated by cough-specific quality of life questionnaire (CQLQ), and the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, IL-8 and substance P in sputum neurogenic inflammatory mediators (SP), neuropeptide A (NKA) and calcitonin gene related peptide (CGRP) were detected.Result: Ridit analysis showed that the clinical efficacy in observation group was better than that in control group (P<0.05). After treatment, scores of coughing at daytime and night, VAS and lung injury caused by dryness and heat were all lower than those in control group (P<0.01). Time to relieve a cough, time to relieve symptoms, and time to vanish cough were all shorter than those in control group (P<0.01). Remission rate of cough and vanishing rate of cough in observation group were higher, while recurrence rate of cough was lower than those in control group (P<0.05). Expect for emotional health and fear of personal safety, scores of other items in CQLQ, the total score and levels of TNF-α, IL-1β, IL-6, IL-8, SP, NKA and CGRP in observation group were all lower than those in control group (P<0.01).Conclusion: Addition and subtraction therapy of Xuanshen Ganju Tang combined with Sanniutang can control systems of cough, shorten coughing course, reduce recurrence rate, improve patients' life of quality, and can inhibit allergic inflammation and neurogenic inflammatory mediators in the treatment of PIC with symptom of lung injury caused by dryness and heat, with a better clinical efficacy than pure compound methoxyphenamine capsules.

This paper aimed to investigate the effect of Yinhua Pinggan granule and San-ao decoction on the immunologic mechanisms of influenza viral pneumonia mice , in order to study the activity of the combined administration of different formulas on influenza A/H1N1 virus. The model of pneumonia was established in mice through nasal dropping influenza virus, and then divided randomly into five groups: normal control group, influenza virus model group, oseltamivir control group, Yinhua Pinggan granule group, and San-ao decoction group. The animals were put to death at the 5th day after gavage administration with the corresponding drugs. The contents in mice serum of TNF-α, IL-6 and IFN-γ were respectively measured by ELISA. The mRNA expressions of TLR3/7, MyD88, JNK, p38MAPK and NF-κB p65 in lung tissues were respectively detected by RT-PCR. The protein expressions of JNK, p38MAPK and NF-κB p65 in lung tissues were determined by immunohistochemical analysis, respectively. According to the results, Yinhua Pinggan granule and San-ao decoction could significantly decrease the levels of TNF-α and IL-6, increase the level of IFN-γ in mice serum of lung tissues, significantly reduce the gene expressions of TLR3/7, MyD88, JNK, p38MAPK and NF-κB p65 in influenza virus-infected mice lung tissues, and significantly reduce the protein expressions of JNK, p38MAPK and NF-κB p65 in lung tissues. Furthermore, the regulatory effect of Yinhua Pinggan granule was superior to that of San-ao decoction. In conclusion, Yinhua Pingan granule and San-ao decoction have the therapeutic effect on pneumonia mice infected by H1N1 virus . The anti-influenza mechanisms of Yinhua Pinggan granule and San-ao decoction may be the results of interactions by regulating the immunologic function of influenza virus-infected mice and TLR3/7 signaling pathway with multiple links of the gene and protein expressions. Moreover, the combined administration of warm-natured and cold-natured Yinhua Pinggan granule with the effects of detoxification and exhalation has a better effect than the single administration of warm-natured San-ao decoction.

Objective: To study the effects of serum and its components on biofilm formation of Pseudomonas aeruginosa. Methods: 96 well microplates combined with crystal violet staining was used to detect the effects of serum, albumin and transferrin on biofilm formation of Pseudomonas aeruginosa. And confocal laser scanning microscope was used to observe the morphology of the biofilm. Results: The biofilm of PAO1 was significantly enhanced from 2.26±0.42 to 3.42±0.08（t=4.71, p<0.01）with horse serum and but reduced to 0.807±0.10（t=4.71,p<0.01） by human serum; And the total biofilm biomass was significantly increased and clump-changed with horse serum, but decreased and scattered in distribution by human serum. Besides, horse serum could also enhance the biofilm formation of part of the clinical isolates of Pseudomonas aeruginosa, however, human serum could inhibit the biofilm formation of all of the clinical isolates. And 2.5g/L albumin could significantly enhance the biofilm of PAO1 from 1.96±0.22 to 2.54±0.18（t=3.55，p<0.05）, but 5 g/L could reduce the biofilm of PAO1 from 1.85±0.36 to 0.84±0.24（t=4.03，p<0.05）. Conclusion Horse serum and albumin could significantly promote the biofilm formation of Pseudomonas aeruginosa, but human serum and transferrin could decrease its biofilm formation.

Objective: To establish and evaluate a method of enriching bacteriophages in natural water based on ferric trichloride-polyvinylidene fluoride (FeCl₃-PVDF)membrane filter. Methods: Based on the principle of flocculation concentration, the method of recovering bacteriophage from water sample was established by using iron ion flocculation combined with membrane filter. The titer of phage was determined by Agar double layer method. The recovery efficiency of phage was detected by phage fluorescence staining and real-time fluorescence PCR reaction. Water samples from different sources were collected for simulation experiment to evaluate the enrichment effect. At the same time, the sewage discharged from hospitals was taken as the actual water sample, and the common clinical drug-resistant bacteria were used as the host indicator bacteria to further analyze the enrichment effect of FeCl₃-PVDF membrane filter rapid enrichment method on the bacteriophage in natural water samples. Results: The method of enrichment of bacteriophages in natural water by iron ion concentration 50 mg/L and PVDF membrane filter was established. The recovery rate of this method for bacteriophage was 93%-100%. Under the multi-functional microscope, it was found that the bacteriophage of the enriched water sample increased significantly and the fluorescence value of the enriched water sample determined by the enzyme labeling instrument was about 13 times as high as that before enrichment. After concentration of the actual water samples from the hospital drainage, the positive rate of bacteriophage isolation in the concentrated group and the non-concentrated group was 23% and 4%, and the fluorescence value in the concentrated group was 2-24 times as high as that of the non-concentrated group. Conclusion: The method of FeCl₃-PVDF membrane filter is a simple, efficient and rapid method for enriching bacteriophages in different water samples.
