Objective To study the relationship between hyperthermia secondary to extensive cerebral infarction and short-term prognosis.Methods 208 extensive cerebral infarction cases were divided into two groups: the fever group(T≥37.5℃, n=82) and non-fever group(T

Chemokine is a kind of cytokine that induces cell transport to inflammation sites. It plays an important role in controlling the differentiation, development and directed migration of immunocytes. CCL20 is one of the important members of chemokine family, and it belongs to CC subfamily. Its receptor is CCR6. CCL20 can be expressed in activated monocytes, T lymphocytes, dendritic cells and endothelial cells, and CCR6 can be expressed in liver, lung, and lymphoid tissues. The expression of CCL20 can be induced by tumor necrosis factor α (TNFα), interleukin 1β (IL-1β), IL-17, CD40 ligand and interferon γ (IFN-gamma;). In summary, CCL20 plays an important role in tumor growth, invasion and metastasis (mainly refers to intrahepatic metastasis). Copyright© 2011 by TUMOR.

Objective To survey the distribution of TCM constitution of Guangxi adults.Methods Identification questionnaire of constitution in TCM was performed to identify the TCM constitution types of 3000 adults who were taken medical examination in the first affiliation hospital to GuangXi TCM university Health Administration Center or of permanent residence in Nanning,Wuming,Qinzhou,Hezhou.Results 612 cases (20.4％) had constitution of phlegm-dampness in 504 cases (16.8％) had constitution of phlegm-dampness,431 cases (14.3％) had constitution of yang asthenia,422 cases (14.1％) had constitution of qi asthenia,353 cases (11.8％) had constitution of damp-heat,348 cases (11.6％) had constitution of yin asthenia,159 cases (5.3％) had constitution of qi stagnation,100 cases (3.3％) had constitution of blood stasis,and 71 cases (2.4％) had allergic constitution.Conclusion There were 9 kinds constitutions in the adults of GuangXi province.The constitution of yin-yang harmony was the most among all.Most male had phlegm-dampness or damp-heat constitution.Most female had yang asthenia,qi asthenia,qi stagnation or yin asthenia constitution.

To investigate the regulation of osteoclast inhibitory lectin (OCIL) mRNA expression by prostaglandin E2 ( PGE2 ) in rat osteoblastic cells and the involved signaling pathways. Rat primary osteoblasts and UMR106 osteoblast-like cells were cultured and treated with various doses of PGE2 or regulators of different signaling pathways for different periods of time, the cells were then harvested at indicated dates. Total RNA were isolated and OCIL mRNA expression were studied by real-time PCR. PGE2, Forskolin, db-cAMP, and A23187 increased OCIL mRNA by 2. 38 fold,4. 2 fold,4. 5 fold, and 5. 1 fold ( all P＜0. 01 ) respectively, while PMA downregulated OCIL mRNA expression by 50% ( P＜0. 01 ). KT-5720, verapamil, W7, and PD98059 downregulated PGE2 induced OCIL mRNA expression by 56%, 40%, 65%, and 60%, respectively( all P＜0. 0l ). While chelerythrine enhanced PGE2 induced OCIL mRNA expression by 30% ( P＜0. 05 ). PGE2 up-regulated the expression of OCIL in rat osteoblastic cells via PKA, MAPK, and Ca2+/Calmodulin signaling pathways.

Objective To estimate the clinical value of 4 methods of endometrium preparation for frozen‐thawed embryo transfer(FET ) cycle .Methods Total 320 FET cycles completed in center of reproductive medicine of Qingyuan people′s hospital from March 2013 to March 2015 were retrospectively analyzed ,and divided into 4 groups :natural cycle group(group A ,n=70) ,o‐vulation‐inducing cycle group(group B ,n=152) ,hormone replacement treatment(HRT) cycle group (group C ,n=74) ,down‐regu‐lated HRT cycle (group D ,n=24) .The pregnancy outcomes were followed and compared among these different 4 groups .Results In FET cycles ,the clinical pregnancy rates and implantation rates of group B ,group C and group D were significantly higher than that of group A (P<0 .05) ,there were no significant differences in the rates of multiple pregnancy ,biochemical pregnancy ,early a‐bortion and ectopic pregnancy among 4 groups(P>0 .05) .However ,the rank of the FET cycle of group D was significantly higher than those of the other three groups(P<0 .05) .Conclusion In FET cycles ,the methods of ovulation‐inducing ,HRT and down‐reg‐ulated HRT all have favorable clinical outcomes ,and the method of down‐regulated HRT is more suitable for patients with previous implantation failure .

Objective To evaluate the mode of referral by response time for inter-hospital transfer of critically ill pediatric patients,and subsequently some measures taken for minimizing the response time in referral process.Methods A total of 9231 patients (≤14 years) transferred from primary hospital were included in a cross-section study.Information about age,sex,referral radius,the seasonal variation for inter-hospital transport of critically ill pediatric patients,time of referral telephone call and response time were collected.All computations were performed using the Statistic Package for Social Sciences for Windows version 18.0.Differences between groups were assessed by x2 tests or Wilcoxon test or Kruskal-Wallis for categorical data.Results Among all critically ill pediatric patients for the inter-hospital transfer,male to female ratio was 2.24:1,and the majority of patients were neonates and infants.Median retrieval mobilization time was 30 min (interquartile range,20-50 min).This study has demonstrated that referral time,age categories,referral radius,different years and seasons were associated with response time.Conclusions With the improvement of technologies and management mechanism,the response time was apparently minimized since the beginning of interhospital transportation.But there is still plenty of room for shortening rsponse time compared with advanced Westem countries.

Objective To investigate the adrenal histopathology damage in critically ill non-survival children,and the incidence of adrenal damage,and to explore the risk factors for the adrenal hemorrhage and necrosis in critically ill children.Methods A total of 141 critically ill non-survival children was admitted in this study in Hunan Children's Hospital from January 1,2005 to December 30,2012.Clinical data in children were systematically collected,including age,sex,sodium,potassium,blood gas analysis,liver and kidney function,blood clotting function,etiology,treatment and pediatric clinical illness score (PCIS) or neonatal critical illness score (NCIS),and pathological data.All data were analyzed by SPSS 18.0.Results Logistic regression analysis showed the factors of adrenal hemorrhage and necrosis of critically ill non-survival children were sepsis,PCIS score ＜ 80 critically ill children are risk factors for adrenal hemorrhage necrosis (P ＜ 0.05),ORwas 3.659 (95％ CI:1.344-9.965),and 2.325 (95％ CI:1.028 -5.258).Intravenous corticosteroids were protective factors for critically ill non-survival children with adrenal hemorrhage necrosis (P ＜ 0.05),and ORwas 0.377 (95％ CI:0.163-0.875).Conclusions There were two significant risk factors of adrenal hemorrhage and necrosis:sepsis and critical illness score less than 80 points.Intravenous corticosteroid is a protective factor in critically ill children.

Objective To explore the method for repair of total avulsion of 2~4 fingers and to find the best procedure. Methods The wrap-round flap with part toenail combind with the dorsal pedical flap to repair soft tissue defect of the dorsal of finger and part of the palmar of finger, the second simepulp flap to repair soft tissue defect of the palmar of finger,transfer of two tissues with one pedicle to repair total avulsion of 2~4 fingers. Results All of 9 composite transplants in 6 cases were survived,the received areas were primary healing in 8 finger,1 case repaired by the bilateral wrap-round flaps and second simepulp flaps for index and middle finger,the distal phalanx of middle finger necrosis because of dislocation of DIP,3 months later,injury healed after the necrosis of phalanx excised,but the nail and the nail bed were dead.Except 1 case which the grafted skin necrotized in the donor area of the big toe,the rest had primary healing.All cases were followed up 6~14 months,the activity of joints were: MP 0-70,PIP 0-40.The repaired pulps had excellent appearance,the nail was fine,1 finger's mail was atrophy and 1 finger's nail was defect.The donor area had good fountion without pain and edema,the grafted skin had normal color and the activity of joints were nomal. Conclusion The wrap-round flap with part toenail combined with the second simepulp flap is a good approach in treatment of the skin avulsion injury in the finger.
