Objective To investigate the prevalence of human metapneumovirus (HMPV)infection in patients with respiratory infection in Fuzhou area and compare their epidemic features and clinical characteristics with those of infected with respiratory syncytial virus (RSV). Methods A total of 153 sputum or pharyngeal swab samples from patients with respiratory tract infection were collected in Fujian Provincial Hospital in consecutive winter and spring seasons from 2005 to 2007. HMPV was detected by nested reverse transcriptase-polymerase chain reaction (RT-PCR) and RSV was tested by RT-PCR. Parts of PCR products were sequenced and analyzed using DNAMAN software. The clinical symptoms, signs and epidemiology of the respiratory tract infections caused by HMPV and RSV were compared. Results In the 153 specimens, 32 (20.9%) were positive for H MPV, 26 (17.0%) were positive for RSV, and 8 were both HMPV and RSV positive. Nucleotide sequences of three 432-bp PCR products were 100% identical and submitted to GenBank (the accession No. DQ887758).Phylogenetic tree analysis of nucleotide sequences revealed that the three isolates clustered in HMPV belonged to genotype A with part of mutation. Twenty-six samples (26. 7%) were HMPV positive from Dec 2005 to Apr 2006 and 6 (10.7%) were positive from Dec 2006 to Apr 2007. The RSV detection rate was opposite of HMPV. The mean age of RSV infection in children was (2.65±2.65)years old and HMPV infection was (4.58 ±3.35) years old. The main clinical manifestations of both RSV and HMPV infections were cough, sore throat and fever. Conclusions Both HMPV and RSV are the major pathogens of respiratory tract infection in Fuzhou area and HMPV and RSV coinfection could be detected. HMPV infected children are older. The clinical features of HMPV and RSV infections are similar. Single genotype of HMPV is detected in Fuzhou area in this study.

Objective To evaluate the effect of Xingqi Tongfu Pad on the intestinal functions of children with acute abdomen after surgery. Methods The random digit table was used to randomize 146 patients with acute abdomen into treatment group (n=71) and control group (n=75) according to their registration number. In the control group, the patients only received normal treatment and nursing, while those in the treatment group received Xingqi Tongfu Pad for the acupoint application in addition to routine treatments. The two groups were compared in terms of the time of bowel sound recovery , the exhaust defecation time and gastrointestinal dysfunction score. Results The bowel sounds and the first exhaust and defecation in the treatment group appeared obviously earlier than those in the control group . The score on gastrointestinal dysfunction in the treated group was significantly higher than that of the control group (P<0.05). Conclusions Xingqi Tongfu Pad can promote the recovery of gastrointestinal function after abdominal operation. It deserves popularization for its positive effect, cheap price and easy operation.

Objective: To investigate the effect of the frenulum identification positioning method with a disposable suture device in circumcision for the prevention of postoperative penile frenulum malposition. METHODS: Totally 212 patients with phimosis or redundant prepuce underwent circumcision from March 2015 to September 2016, including 109 cases of conventional circumcision (the control group) and 103 cases treated by frenulum identification positioning with a disposable suture device (the observation group). We observed the postoperative position of the penile frenulum and median raphe and compared the deviation angles of the frenulum between the two groups of patients. RESULTS: The median of penile frenulum deviation angle (interquartile range) was 0 (3.56) in the observation group, significantly smaller than 12.41 (19.59) in the control (P <0.001, P = 0.000). And the rate of frenulum deviation was remarkably lower in the former (8.74% ［9/103］) than in the latter group (66.06% ［72/109］) (P <0.01). CONCLUSIONS Circumcision using the frenulum identification positioning method with a disposable suture device can effectively avoid postoperative penile frenulum malposition. With the advantages of safety and easy operation, it deserves clinical application and popularization.
