The ring forms had multinuclei, and the late trophozoites trended to form band. The schizonts and gametocytes were somewhat alike to Plasmodium vivax. PCR amplification confirmed that the patient was infected by P.knowlesi.

Objective To observe the clinical efficacy and safety of dexmedetomidine on analgesic effect in patients after thyroid surgery.Methods A total of 102 patients after thyroid surgery were divided into control group and treatment group,each group 51 cases.Patients in both groups were given thyroid operation.Patients in both groups were given sulfentanyl 10 μg + 0.375％ ropivacaine mixture 20 mL before operation,granisetron hydrochloride injection 5 mg by intravenous drip,once a day after operation.Control group was given midazolam hydrochloride injection 0.03 mg · kg-1 by intravenous drip before operation.Treatment group was received dexmedetomidine hydrochloride injection 1 μg · kg-1 by intravenous drip before operation.The clinical efficacy,3-endorphin (3-EP),interleukin-6 (IL-6),C-reactive protein (CRP) and adverse drug reactions in two groups were observed.Results After treatment,total effective rates in treatment and control groups were 92.16％ (47/51 cases) and 78.43％ (40/51 cases),with significant difference (P ＜ 0.05).After treatment,β-endorphin in control group and treatment group were (268.47 ± 29.58),(284.47±30.05) pg· L-1,CRP were (4.47 ±0.54),(4.07 ±0.42)mg · L-1(P＜0.05).The adverse drug reactions in treatment group were lethargy,respiratory depression,nausea and vomiting,the incidence of adverse drug reactions was 5.88％ (3/51 cases).The adverse drug reactions in control group were itching,respiratory depression,drowsiness,nausea and vomiting,the incidence of adverse drug reactions was 11.76％ (6/51 cases,P ＞ 0.05).Conclusion The analgesic effect of dexmedetomidine after thyroid surgery is effective with high safety.

Objective To evaluate the clinic efficacy of sufentanil and remifentanil by target- controlled infusion (TCI) combined with propofol in patients undergoing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).Methods Sixty patients,ASA Ⅰ ～ Ⅱ,undergoing elective EBUS-TBNA were randomly divided into group S ( sufentanil group),group R (remifentanil group) and group SR (sufentanil + remifentanil group),each group were twenty patients.The anesthesia of all groups is propofol intravenous anesthesia with 2％ lidocaine topical anesthesia,to controll BIS between 50 and 60 during surgery.Heart rate(HR),mean arterial pressure(MAP) pulse oxygen saturation( SpO2 ) and respiratory rate (RR) were recorded and compared 5mins after entering room(T0),30mins after the beginning of surgery(T1 ) and after surgery(T3).Arterial blood gas and the times of cough during surgery were also recorded and compared in all groups.The use of propofol and lidocaine,the wake-up time,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were also obtained.Results ( 1 ) RR decreased distinctly in group R and PaCO2 increased distinctly in group S and group R compared with that of group SR (P ＜0.05) during surgery.(2)The times of cough and the wake-up time lessened distinctly in group R and group SR compared with that of group S ( P ＜0.05 ).(3) The use of propofol and lidocaine,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were similar in all groups ( P ＞ 0.05 ).Conclusion Sufentanil compounded remifentanil by TCI combined with propofol is a safe and feasible anesthesia option for EBUS-TBNA,which provides better efficacy,high satisfaction and less side effects compared with using alone of sufentanil and remifentanil respectively.

Butyric acid can be used to produce cellulose butyrate fiber and ester derivatives,and to be applied in foodstuffs and perfume industries.Recent researches have found that butyric acid is a preferred carbon source for colonic epithelial cells,and can inhibit histone deacetylase,showing great anticancer potentials.With more and more functions of butyric acid being found and applied in bio-related fields,and with consumer's growing preference to bioproducts,biotechnological production of butyric acid will receive more competence than petroleum-based chemical synthesis.Low product concentration and poor selectivity are presently the main restricting factors.Workers have made considerable progress on more cheep carbon sources,optimization of fermentation process,simplifying downstream processing,and genetic engineering of producing strains.Any achievement on these aspects in the future can contribute to put fermentation of butyric acid into industry.

0.05)respectively.Histological changes of donor biopsy before implantation and 30 min after reperfusion were similar in two groups.Conclusion Within the cold ischemic time considered,Celsior and UW solution are equal in effectiveness for clinical use in liver transplantation.

Objective To understand human rhinovirus (HRV) etiology of acute lower respiratory tract infection (ALRTI) in children in Shanghai area and establish a nested reverse transcription- polymerase chain reaction (nested RT-PCR) assay.Methods Three hundred and forty-two naso- pharyngeal secretion (NPS) samples from ALRTI cases who were hospitalized were collected during January 2005—December 2005.Nested RT-PCR techniques were used to detect HRV-specific RNA.The PCR products were sequenced and data of nucleotides were analyzed.The proportion of HRV infection in children with ALRTI,the distribution of gender,age and season,and clinical char- acteristics were also investigated.Results Forty-six (13.5%) of 342 samples were HRV positive detected by nested RT-PCR.The sequences of 15 positive samples shared high homology of 83%- 97% with HRV sequence in GenBank.Within the 15 positive samples,nucleotide homology varied from 64.4% to 98.4%,and the ratio of genetic variation was from 1.6% to 48.3%./00.These 15 ampli- cons attribute to the two branches of HRV cladogram.The sequences of 15 amplieons were highly varied,in which single nucleotide mutation and several nearby nueleotides mutations were found. Ribonucleotide deletion and insertion in the nucleotide sequence was also found.HRV positive sam- ples were detected in 33 boys and 13 girls,respectively.The ratio of infection cases between boys and girls was 2.5:1.Of 46 HRV infected cases,27 (58.7%) were less than 12 months of age and 38 (82.6%) were less than 3 years old.HRV infected ALRTI occured all the year round and peaked from March to May.Of the patients whose NPS samples were HRV positive detected by nested RT-PCR,45 patients were diagnosed with bronchopneumonia and 1 was diagnosed with asthmatic bronchitis.Fever of most patients was moderate.The peripheral blood leukocyte counts in thirty-nine (84.8%) patients were less than 10?10~9/L.Neutrophil percentages in thirty-seven (80.4%) patients were less than 0.50.C-reactive protein of thirty-six (78.3%) patients were less than 8 mg/L. All of these features were the characteristics of viral pneumonia.The complications were not common and conditions of most patients were not severe.All the children were cured.Conclusions This nes- ted RT-PCR technique is highly specific,rapid and convenient for the detection of HRV RNA in NPS of patients with ALRTI and the genome of HRV viruses is highly variable.The incidence of HRV infection predominates in children in Shanghai area.ALRTI of HRV is short of specificity and condi- tions of most patients are not severe and their prognoses are fine.

Objective To investigate and analyze the death situation of children aged under 5 year old in a class 3A hospital during 2007-2015 to provide a basis for formulating corresponding interventional measures to reduce the disease mortality of children.Methods The medical records of children death in this hospital during 2007 2015 were retrospectively analyzed.Results The mortality rate of children under 5 years old in this hospital during 2007-2015 showed a decreasing trend year by year.There was the statistically significant difference in the mortality rates among different years,between male and female (3.58 ％vs.2.10％) and between rural family registers and non-rural family registers(P＜0.05);the neonatal mortality rate was highest (50.45 ％);the top 5 places of death causes were premature delivery or low birth weight newborns,respiratory system diseases,nervous system diseases,congenital diseases and accidents.Conclusion The key for reducing the children mortality rate is to strengthen the perinatal health care,strengthen prenatal examinations and pregnant examinations,prevent the occurrence of respiratory system disease,pay attention to the influence of various factors on children health and prevention and treatment of accidents.
