Objective To evaluate the effect of anterior minimally invasive plate osteosynthesis (MIPO) for treatment of middle humeral shaft fracture.Methods From November 2011 to March 2014,10 cases of middle humeral shaft fracture were treated using MIPO via the anterior approach (MIPO group).Another 26 cases treated by open reduction and internal fixation (ORIF) of the middle humeral shaft fracture between October 2010 and March 2014 were included as controls (ORIF group).Fracture fixation using the 4.5 mm locking compression plate (LCP) was performed in both groups.Parameter measurements included operative time,intraoperative fluoroscopy times,grafting rate,intraoperative blood loss,postoperative drainage,hospital stay,bone healing time and complications.Results MIPO and ORIF groups differed significantly with respect to intraoperative blood loss [(93.5 ± 25.6) ml vs (325.3 ± 158.3) ml],intraoperative fluoroscopy times [(13.2 ± 6.1) vs 4.0 (0-6.0)] and hospitalization [(11.9 ± 1.7)days vs (18.0 ±4.7)days] (P ＜0.05).Bone grafting and drainage were not performed in MIPO group,while bone grafting rate was 54％ and postoperative drainage volume was (120.4 ± 69.6) ml in ORIF group (P ＜0.05).MIPO and ORIF groups were comparable with respect to operative time [(79.0 ± 22.0) min vs (97.5 ± 30.8) min],bone healing time [(15.2 ± 2.5) weeks vs (18.2 ± 4.8)weeks] and postoperative complications (10％ vs23％) (P＞0.05).Conclusion Anterior MIPO is an effective procedure for treatment of middle humeral shaft fracture,with advantages of small trauma,less bleeding,low risk of nerve injury and high rate of fracture healing.

Objective To understand the status of soil-transmitted nematode infections,as well as the awareness and healthy behavior on soil-transmitted nematodiasis in rural residents of Dezhou City. Methods Six villages were selected according to the stratified sampling method;the permanent resident population aged 3 years or above was determined as the investigation objects. The modified Kato-Katz technique was adopted to detect the eggs of Ascaris lumbricoides,hookworm and Trichuris trichiura in the feces of the residents,and the method of cellophane anal swab was used to detect the Enterobius vermicularis infection in children under 12 years old. More than 50 households in each investigated site were randomly selected to investigate the awareness status on nematodiasis prevention and treatment and the condition of healthy behavior formation. Results A total of 2 294 residents were detected by Kato-Katz methods,11 of them were positive,and the total infection rate of soil-transmitted nematodes was 0.48%. To-tally 260 children were detected and 40 were infected with E. vermicularis,and the infection rate was 15.38%. A total of 898 resi-dents were investigated in the household survey and the awareness rate of nematodiasis prevention and treatment was 44.99%,the proportion of residents with healthy behavior was above 70%. Conclusions The infection rate of soil-transmitted nematode is low in rural areas of Dezhou City,but the infection rate of E. vermicularis in children is higher. The condition of healthy behavior forma-tion is satisfying,but the awareness rate of nematodiasis prevention and treatment of the residents is low. Therefore,the control measures as well as healthy education still should be strengthened.

Objective To identity the risk factors for supine hypotension syndrome (SHS) after spinal anesthesia in parturients.Methods A total of 204 parturients,scheduled for elective cesarean section,were divided into either control group or SHS group depending on whether or not SHS (systolic blood pressure [SBP] in the upper extremity decreased by ＞ 30 mmHg or decreased to ＜ 80 mmHg) developed after spinal anesthesia.The baseline patient characteristics such as age,body height and weight,gestational weeks and biparietal diameter were recorded.Supine stress test (SST) was performed.Heart rate,blood pressure in upper and lower extremities,perfusion index,pleth variability index and intravesical pressure were recorded when patients were in supine position and in left lateral position before spinal anesthesia.The risk factors of which P values were less than 0.05 would enter the multi-factor logistic regression analysis to stratify the risk factors for SHS.Results Among the 204 patients,99 cases developed SHS after spinal anesthesia,and the incidence was 48.5％.Logistic regression analysis showed that maternal body weight,biparietal diameter,the difference in SBP between upper and lower extremities in supine position,the difference in SBP in upper extremities caused by changing position and positive SST were risk factors for SHS after spinal anesthesia (P＜0.05 or 0.01).Conclusion Maternal body weight,biparietal diameter,the difference in SBP between the upper and lower extremities in supine position,the difference in SBP in upper extremities caused by changing position and positive SST are risk factors for SHS after spinal anesthesia in parturients.

Objective To find the rule of the distribution of H antigens on AB subgrouperythrocytes.Methods ABO subgroups were confirmed by using serological and molecular biology (PCR-RFLP) methods. AB subgroup with strong H was defined as red cell agglutination by anti-H of 2 scores or more higher than that of B cells.Results Strong H was only found in certain AB subgroups ,CisAB(100%),B(A)(100%), AxB(46.2%) and A2B(43.6%), but seldom in others among Chinese population.Conclusion The fact that H type-3, which comes from A type-2, can hardly be transferred by B and weak A glycosyltransferase can help to explain why some ‘strong’ H combines with ‘weak’ A in AB erythrocytes. Why only little H can be found in 53.8% AxB, 56.4% A2B and all A3B, AmB subgroup samples still cannot been explained.

Objective To evaluate the effect of dexmedetomidine on intraoperative wake-up test in patients undergoing scoliosis surgery.Methods Sixty ASA Ⅰ patients,aged 13-18 yr,scheduled for elective scoliosis surgery,were randomly divided into 2 groups (n =30 each) ∶ sufentanil group (group S) and dexmedetomidine combined with sufentanil group (group DS).Anesthesia was induced with sufentanil,etomidate and cisatracurium,and maintained with target-controlled inhalation of sevoflurane combined with target-controlled infusion of sufentanil in both groups.In group DS,dexmedetomidine 0.2 μg·kg-1 · h-1 was infused during operation,while the equal volume of normal saline was given instead in group S.Before the wake-up test,cisatracurium infusion was stopped,the end-tidal concentration of sevoflurane was adjusted to 0,and the target effect-site concentration of sufentanil was adjusted to 0.1 and 0.08 ng/ml in groups S and DS,respectively.The wake-up test was performed 5 min later.The wake-up time and bucking/restlessness and cardiovascular events during the wake-up test were recorded.The occurrence of intraoperative awareness was recorded in the patients who were followed up after operation.Results No cardiovascular events occurred during the wake-up test in group DS.The wake-up time was significantly shorter and the incidences of cardiovascular events and bucking/restlessness were significantly lower in group DS than in group S (P ＜ 0.05).No intraoperative awareness occurred in the patients.Conclusion Dexme-detomidine can be used for intraoperative wake-up test in patients undergoing scoliosis surgery,with shorter wakeup time,stable hemodymamics and fewer adverse reactions.
