Objective To explore diagnosis,treatment and prognosis of intestinal atresia(IA) in neonates,so as to increase the healing rate.Methods Surgical treatment was given to 29 cases of congenital IA from Apr.2004 to Nov.2008.Comprehensive analysis was carried out on clinical manifestations and flat X-ray.All cases were with vomiting,15 cases were with normal fetal faeces.Stomach and intestinal atresia were observed in the upper abdomen in 19 cases,fluid levels in generous stomach and expended intestines were seen in 21 cases by X-ray.All children underwent operation,including ileum atresia(16 cases),duodenal atresia(7 cases),and jejunal atresia(6 cases).The types of atresia were type Ⅰ(9 cases),type Ⅱ(9 cases),type Ⅲa(9 cases),type Ⅲb(1 case) and type Ⅳ(1 case).Nine cases were treated with septum resection and then anastomosed longitudinally,3 cases underwent end-to-end anastomose and 17 underwent end-to-back anastomose.All cases were served in intravenous hyperalimentation.Results All cases lived postoperatively,and 1 child gave up for postoperatively treatment.Twenty-eight cases were cured.There was 1 case of obstruction of anastomatic,and was cured by non-operatively treatment.There was no anastomatic leakage and wound disruption.Twenty-six cases were followed up for 3 months and up to 4 years.These symptoms had no relapse.Conclusion Early diagnosis,appropriate surgical procedure and surrounding operation management are crucial for improving the cure rate.

OBJECTIVETo explore Chinese medical syndrome typing features of epigastric pain and its association with gastroscopic manifestations.

METHODSUsing associated rules data mining method, an analysis study was performed in 234 patients with epigastric pain by combining holistic Chinese medical syndrome typing and results of gastroscopic examinations.

RESULTSPi-Wei deficiency cold syndrome (PWDCS) was associated with pale gastric mucosa, or superficial ulcers accompained with unobvious redness and swelling. Inversed Gan-qi invading Wei syndrome (IGIWS) was associated with bile regurgitation. Damp-heat stagnating in the middle jiao syndrome (DSMJS) was associated with obvious redness and swollen mucosa, or ulcers accompanied with yellow and white fur. Wei-yin exhaustion syndrome (WYES) was associated with coarse mucosa and exposed blood vessels, or rare mucus. Retention of blood stasis in Wei syndrome was associated with bulged swelling and erosion. Indigestion impairing Wei syndrome (IIWS) was associated with retention of water and food, or more mucus attached. The endoscopic manifestations of PWDCS and DSMJS occurred most frequently, while PWDCS and IGIWS ranked the first place in macroscopic Chinese medical syndrome typing.

CONCLUSIONSThe manifestations of endoscopic features were closely associated with Chinese medical syndrome typing. The syndrome typing features of epigastric pain could be objectively and further grasped by summarizing syndrome typing laws using modern devices such as gastroscopic examinations, thus improving the accuracy of clinical syndrome typing.

Objective To explore the interaction between serum melatonin and the status of disease and probe the effect factor of serum melatonin change in asthmatic children.Methods Serum melatonin was measured in asthmatic children with 15 cases of mild persistent asthma,15 cases of moderate persistent asthma,15 cases of severe persistent asthma,15 cases of stable asthma and 15 cases of normal subjects by enzyme-linked immunosorbent assay(ELISA).Results The levels of serum melatonin in the 5 groups of mild persistent asthma,moderate presistent asthma,Severe Persistent asthma,Stable asthma,control subject were(22.76?5.16)ng/L,(16.79?3.35)ng/L,(11.54?1.45)ng/L,(22.06?3.36)ng/L,(28.72?4.32)ng/L,respectively.There were significant differences between any of them(Pa

Objective To explore the effect of Melatonin(MT) on CD4+CD25+ regulatory T cell (CD4+CD25+Tr)and airway inflammation in asthmatic rat.Methods Thirty-two SD rats were randomly divided into 4 groups,8 rats in each group.Asthmatic group:rats were immunized on day 1 and 7 by intraperitoneal inject of mixture of ovalbumin(OVA) and aluminumhydroxide.From day 14,the animals were allenged with aerosolized OVA for 20 min per day for 7 consecutive days.MT group:OVA-sensitized rats were injected intraperitoneally with 0.1 mg/kg MT 30 min before each OVA challenge.Dexamethasone group:OVA-sensitized rats were injected intraperitoneally with 0.5 mg/kg Dexamethasone 30 min before each OVA challenge.Control group:OVA for inhalation and MT for intraperitoneal injection was replaced with saline.After the last challenge,peripheral blood was stained to count the percentage of eosinophil(EOS).Then the rats were lavaged and total leukocytes counts in bronchoalveolar lavage fluid(BALF) were performed after staining with Wright-Giemsa staining.The EOS counts around the airway was counted after the histological section of lung staining with hematoxylin and eosin staining.The serum level of immunoglobulin E(IgE) was detected by immunoenhancement.The change of CD4+CD25+Tr was assessed with flow cytometry.SPSS 10.0 software was applied to analyze data. Results In asthmatic rats,the CD4+CD25+ Tr/ CD4+T cells ratio had significant negative relationship with the EOS counts around the airway and the total leukocytes counts in BALF (r=-0.73 P0.05).There was a significant decrease in the percentage of the eosinophils in peripheral blood,the eosinophil counts around the airway,the total leukocytes counts in BALF and the serum level of IgE in MT group compared with asthmatic group (Pa

hMR-1 (Homo Myofibrillogenesis Regulator 1, AF417001) is a novel homo gene, which was firstly cloned in our laboratory. The former studies revealed that hMR-1 is a transmembrane protein which shows protein interaction with sarcomeric proteins like myomesin I, myosin regulatory light chain, alpha-enolase and some cell regulator proteins such as eukaryotic translation initiation factor3 subunit 5 (eIF3S5) and etc. In this work, we focused on cloning the homologous gene of hMR-1 from mouse C57BL/6J and exploring its expression using Pichia pastoris yeast system. Two pairs of primers were synthesized according to the hMR-1 gene homologous sequence on mouse genome chromosome 1. The mouse MR-1 gene (mMR-1) was cloned by PCR following the first round RT-PCR from mouse C57BL/6J spleen total RNA. Sequence analysis verified that mMR-1 gene and amino acids sequence showed 90.4% and 90.1% identity with hMR-1, respectively. The prediction of hydrophobic transmembrane structure of mMR-1 suggested it is also a transmembrane protein. The mMR-1 Pichia pastoris expression vector pPIC9-mMR-1 was constructed by fusion of the flanking mMR-1 ORF in the pPIC9 plasmid. After linearization of pPIC9-mMR-1 with Sal I, the 8.5kb DNA fragment was transformed into Pichia pastoris GS115 strain by electroporation. GS115/Mut+ pPIC9-mMR-1 transformants were selected on minimal methanol medium. Integration of mMR-1 gene into the yeast genome in the recombinants was verified by PCR from the transformants total DNA. The mMR-1 protein was expressed by induction under the concentration of 0.5 % methanol. The specific induced protein of 25 kD molecular mass in SDS-PAGE was confirmed to be the mMR-1 protein by Western blot rsing hMR-1 polyclonal antibody. The expression level of this recombinant mMR-1 protein was about 50 mg/L. The successful expression of mMR-1 in the Pichia pastoris GS115 will facilitate the further functional analysis of the novel gene MR-1 in animal model.

AIMTo explore the effect of acute intra-peritoneal infection on leptin expression levels in peripheral blood and vital organs, and find out the role leptin plays in acute inflammation.

METHODSA cecal ligation and perforation model of rats was established, setting groups of sham-operation, intralipid injection, injury, estradiol injection and insulin injection. A rat leptin radioimmunoassay was used to check serum leptin concentrations at 12 h after the injury, and RT-PCR was also used to detect leptin mRNA expressions in adipose tissue, lung and liver.

RESULTSCompared with serum leptin level of sham-operation group after injury, that of all the other four groups showed no significant difference, while the level of intralipid group was significantly higher than that of injury group and estradiol group. Compared with leptin mRNA expression level of sham-operation group after injury, that of the other four groups had different changes. Leptin mRNA expression of intralipid group was significantly increased in adipose tissue but decreased in lung and liver.

CONCLUSIONLeptin expression levels may be affected by the changes of energy metabolism and neuroendocrine function after injury, which suggests a possible protective role for leptin in the recovery of body homeostasis.

In this paper, the five strains of Polygonatum odoratum were used as the experimental materials to test the supercooling point, freezing point, the degree of supercooling, the transition stage time, cooling time and water composition of the plant tissue. The cold resistance of P. odoratum was analyzed with the Gray Correlation Method. The results showed that the cold resistances of the five strains of P. odoratum were different, and the water content of plant tissue had some relevance with freezing point and supercooling point, whereas, it could not be measured when the moisture content was too low. The order of cold resistance of the five strains of P. odoratum was ZJCY, DYYZ, XYYZ, CYYZ and JZ I.

OBJECTIVE: To investigate the changes of iron content in serum and liver, ferritin content in serum, percentage of myeloperoxidase (MPO) positive granulocyte in rabbits after different serious trauma and to explore the relationship between these changes and multiple organ failure (MOF). METHODS: Rabbit trauma models were established. Iron content in serum and liver, ferritin content in serum and the percentage of MPO positive granulocyte were measured at different time after trauma. RESULTS: After trauma, iron content in serum decreased sharply in early period (12-36h) and increased gradually to normal level in mild traumatic group after 60 h. Iron content in serum remained lower level in severe traumatic and death group 60 h after trauma. Iron content in liver obviously increased in death group. The changes of ferritin content in serum in mild traumatic were not obvious. Ferritin contents in serum in severe injury group and death group were slightly higher in early period and decreased in later period. The percentage of MPO positive granulocyte increased in early period after trauma. The percentage began to decrease 6 d after trauma and returned to normal level in mild traumatic group. The percentage obviously was significantly lower than normal levels in severe traumatic group and death group 6 d after trauma. Some rabbits died 60 h-6 d after severe trauma, and the pathological changes in the other organs were consistent with MOF. CONCLUSION Trauma can cause the serum iron, ferritin levels and percentage of MPO positive granulocyte changes. Severe trauma can cause uncompensated changes of these indicators, which could be the main mechanisms of MOF and death.

PURPOSE: To report the 5-year follow-up results of a randomized controlled trial comparing bipolar transurethral resection of the prostate (TURP) with standard monopolar TURP for the treatment of benign prostatic obstruction (BPO). MATERIALS AND METHODS: A total of 220 patients were randomized to bipolar plasmakinetic TURP (PK-TURP) or monopolar TURP (M-TURP). Catheterization time was the primary endpoint of this study. Secondary outcomes included operation time, hospital stay, as well as decline in postoperative serum sodium and hemoglobin levels. All patients were assessed preoperatively and followed-up at 1, 6, 12, 24, 36, 48, and 60 months postoperatively. Parameters assessed included quality of life, transrectal ultrasound, serum prostate-specific antigen level, postvoid residual urine volume, maximum urinary flow rates (Qmax), and International Prostate Symptom Score. Patient baseline characteristics, perioperative data including complications, and postoperative outcomes were compared. Complication occurrence was graded according to the modified Clavien classification system. RESULTS: PK-TURP was significantly superior to M-TURP in terms of operation time, intraoperative irrigation volume, resected tissue weight, decreases in hemoglobin and sodium, postoperative irrigation volume and time, catheterization time, and hospital stay. At 5 years postoperatively, efficacy was comparable between arms. No differences were detected in safety outcomes except that the clot retention rate was significantly greater after M-TURP. CONCLUSION: Our results indicate that PK-TURP is equally as effective in the treatment of BPO, but has a more favorable safety profile in comparison to M-TURP. The clinical efficacy of PK-TURP is long-lasting and comparable with M-TURP.
