Human metapneumovirus (HMPV)is a recently discovered virus associated with respiratory tract infection. Most infections with HMPV occurred during winter and spring. Children, elderly subjects and immunosuppressed hostsare susceptible. The consequences of HMPV infections ranged from mild upper respiratory tract infection to severe bronchiolitis or pneumonia. There are three different kinds of methods for the diagnosis of HMPV infections, detection of virus antigen-antibody, virus isolation by culture, and RNA detection by reverse transcription-PCR. Symptomatic therapy is the main method of treatment.

Objective To investigate the effect of parental presence on the anxiety of children during induction of anesthesia with sevoflurane. Methods One hundred and twenty children (ASA Ⅰ or Ⅱ ) aged 2-12 yr weighing 12-32 kg were assigned to one of 2 groups using a random number table ( n = 60 each): control group (group C) and parental presence group (group P). Preoperatiave visit was made the day before surgery in both groups. In group P a parent played with toys with the children for 15 min before induction of anesthesia, while in group C a nurse played with them. Anesthesia was induced with 8% sevoflurane in O2 delivered at 6 L/min through a scented face mask held by the parent or anesthesiologist talking with them in soft words. Modified Yale preoperative anxiety scale (mYPAS) was used to measure anxiety of the children during preoperative visit, before and during induction of anesthesia. Induction compliance checklist (ICC) was used to measure behavioral compliance during induction. ICC score ＞ 5 implied failure of induction of anesthesia with sevoflurane. Adverse events were recorded. Results The mYPAS scores were significantly lower before and during induction of anesthesia in group P than in group C (P ＜ 0.05), but there was no significant difference in ICC scores between the 2 groups ( P ＞0.05). There was no failure of induction in group P while in group C there were 3 failures. Cough occurred in 2 patients in group P but in 3 patients in group C. One patient vomited during induction of anesthesia in group C.Conclusion Parental presence is effective in reducing anxiety of children during induction of anesthesia.

The abnormal expression of gastrins and their receptors have close relationship with the occurrenceand the development of some colorectal neoplasms.The high expression of gastrins and their receptors promote colorectal neoplasms cell proliferation and inhibit apoptosis.The biological behavior is mainly rely on the abnormal expression of protein.Using differential proteomics can screen differential expression protein of high expression of gastrin-based colorectal neoplasms in the occurrence and development process,and then with the regulation of specific proteins to achieve the prevention and treatment of colorectal neoplasms purposes.

Transjugular intrahepatic portosystemic shunt (TIPS) has been developed for two decades in order to treat portal hypertension accompanying with upper gastrointestinal hemorrhage and refractory ascites.TIPS may cause the development of hepatic encephalopathy (HE).TIPS induces portalsystemic shunt and leads to hemodynamics chaos. Hepatic encephalopathy belongs to the complications of the portal hypertension. There are many possible predictors of the post-TIPS HE. The relationship between TIPS and HE was reviewed.

In coloreetal cancer,there are multiple abnormally expressed microRNA (miRNA),suggesting that the miRNA may be involved in tumor development process.Recently,more and more evidence shows that miRNA are more stable in the blood,compared with mRNA,which makes circulating miRNA are helpful to become the non-invasive tumor marker for the diagnosis,treatment and prognosis evaluation in coloreetal cancer.

0.05), but the time to initiate effect in the treated group [(14.98?9.28) days] was obviously shorter than that of control group [(30.88?11.32) days] with significant difference (P

Objective To investigate the status of urogenital Ureaplasma urealyticum (Uu) infection and their drug tolerance in our area,so as to guide rational administration for the clinic.Methods Mycoplasma culture and drug susceptibility test were performed for 771 patients with urogenital infaction. The culture,identification and drug resistance of mycoplasma were carried out with one complex mycoplasma kit.Results The positive rate of Uu was 49.9%. The proportional percentage of males was 12.5% and the Uu positive rate was 22.3%,for females,the proportional percentage and Uu positive rate was 87.5% and 60.6% respectively. The population aged 21-40 was susceptible to Uu infection. The most sensitive antibioties to Uu was clindamycin (95.12%),followed by doxycycline (87.57%) and roxithromycin (86.24%).Conclusion The difference of Uu drug sensitivty was significant in different areas. So it is necessary to select antibioties by drug sensitivity. Clindamycin,doxycycline and roxithromycin may are used as preferred antibioties in treating Uu infection in our area. The drug-resistance status of spectinomycin and lincomycin was serious.

Visceral hypersensitivity is the core pathogenesis process of functional gastrointestinal disorders( FGIDs). Numerous studies showed that psychological stress plays a key role in the development of visceral hypersensitivity. Brain center is the key part involved in psychological stress-induced visceral hypersensitivity, especially senior central sensitization. However,the specific pathophysiological mechanism remains unclear. This article reviewed studies on central role mechanism of psychological stress-induced visceral hypersensitivity.

Objective To evaluate the current situation of autoantibodies detection in China in order to improve the quality of detection. Method Inviting letters to partitcipate this evaluation were sent to all laboratories that detect auto-antibodies. Those responding laboratories were enrolled to this study. The testing items included antinuclear antibody, anti-dsDNA antibody, anti-ENA antibody, anti-mitochondrial antobody and anti-smooth muscle antibody. The distribution of samples and the analysis of results were both double-blinded. Result The correct rate of ANA, anti-dsDNA antibody, anti-ENA antibody, anti-mitochondria antibody and anti-smooth muscle antibody was 85.4%,81.8%,36.9%, 66.7%, and 50% respectively. Conclusion Comparing with the first quality control results, the overall results is this evaluation have been improved, but there is still a longway to go.
