Objective To study the effects and advantages of the treatment for simple bone cysts of the long bones in children with AO titanium elastic nail and autologous bone marrow injection. Methods Eighteen patients with a simple bone cyst at humerus or femur were managed with AO titanium elastic in-tramedullary nail combined with autologous bone marrow injection. There were eleven boys and seven girls in total, with the mean age of 8.1 years, ranged from 6 to 12 years. Twelve cysts was located in the proximal end of humerus, five in the proximal end of femur and one in the middle part of the shaft of femur. Twelve cysts were active and six inactive according to Neer standard. Radiographic evaluation was performed three, six, twelve and eighteen months after operation during the 11 to 23 months follow-up by taking anteroposteri-or and lateral X-ray pictures. Then we measured residual radiolucent areas on X-ray pictures and did statistic research with group comparison. Results Six cysts (33.3%) healed completely, and twelve (66.7%) healed with residual radiolucent areas which were visible on X-ray pictures 3 to 6 months after operation. Residual radiolucent areas on X-ray pictures gradually reduced during the different phases and it has statistical signif-icance by group comparison. There was no recurrence or major complication except for one patient with mild irritation of skin caused by the end of the nail up to now. Conclusion The treatment for simple bone cysts of the long bones in children combined with AO titanium elastic nail and autologous bone marrow injection not only has satisfactory healing rate but also can provide early stability to the long bones, and accelerate the healing of cysts which allows early mobilization and thus obviates the long-term need for a plaster cast and decreases the prevalence of the most common complication: a pathological fracture.

Abdominal compartment syndrome (ACS) has been increasingly recognized as a cause for significant morbidity and mortality in many diseases.Great advances have been made in many researches that are dedicated to the treatment of ACS.However,in the field of orthopedics,it has still not aroused enough attention from the orthopaedic surgeons,as the occurrence and development of ACS are occult following pelvic fracture trauma.This review introduces the relevant data and researches about ACS resulting from pelvic fractures.

OBJECTIVE: To investigate the development of clinical pharmacy according to the publication number of literatures in pharmacy periodicals in China. METHODS: General keywords, such as rational administration, pharmaceutical care, training for clinical pharmacist, and special keywords, such as drug utilization, administration analysis, therapeutic drug monitoring(TDM), adverse drug reaction monitoring, medication history, pharmacoeconomic analysis, medicine consultation, were selected for retrieving related literatures from CBM database from 1994 to 2008. Literatures retrieved were analyzed statistically. RESULTS: Clinical pharmacy developed rapidly relatively in recent years. The number of literatures which were retrieved using general keywords was 12 and 15 for using special keywords in 1994. The number of literatures was increases year by year and up to 1 117 and 329 in 2008. However, development orientation of literatures was unbalanced. Literature about rational administration, drug utilization and administration analysis constituted a high proportion while development of clinical pharmacy should be enhanced in respect of clinical pharmacist training, medication history writing, medicine consultation and adverse drug reaction monitoring. CONCLUSION: Disadvantage in disequilibrium of development should be changed as long as clinical pharmacy develops rapidly in order to promote its overall development.

Objective To investigate the feasibility and superiority of combined spinal epidural anesthesia incesarean section.Methods 100 lying-in women who experienced cesarean section were collected and divided into combined spinal epidural anesthesia group(CSEA,n=50)and continuous epidural anesthesia group(CEA,n=50).The change of heart rate(HR),blood pressure(BP)and saturation of peripheral oxygen(SpO2),HR and BP of lyingin womeu in pre-anesthesia,5min,15min post-anesthesia and the time of taking effect,time between beginning of anesthesia and laboar of newborn were observed.The side effects of surgical anesthesia and Apgar score of newborn were compared between the two groups.Results There were no difference in clinical data,change of HR,BP and spO2 between two groups.The anaesthetic time of taking effect and the time between beginning of anesthesia and labour of newborn in group CSEA were shorter than in group CEA(all P＜0.05).Conclusion The combined CSEA and CEA was safe and efficient in cesarean section,and CSEA had greater efficacy than CEA in cesarean section.

ObjectiveTo investigate the incidence, clinical features and preventive measurement of secondary hepato-biliary neoplasm (HBN) in patients with hepatolithiasis. MethodA clinical retrospective study was made on 27 hepatobiliary malignancy patients found among 556 consecutively admitted cases of hepatolithiasis from Jan. 1996 to Sep. 2000.Results The average incidence of hepatobiliary malignancy in patients with hepatolithiasis is 4.8%. In this series, preoperative definite diagnosis was made in 4 cases (4/27, 14.8%). Atypical liver abscess, refractory biliary system infection, progressive obstructive jaundice, CT or BUS scan abnormal findings, and epigastric masses are all clues to concurrent malignancy in patients of hepatolithiasis. ConclusionThere is high incidence of hepatobiliary malignancy in hepatolithiasis patients. Prophylactic partial hepatectomy for segments with stone and chronic infection may be an important measure to prevent ensuing malignancy.

Objective To investigate the relationship between pharmacokinetics(PK) and pharmacodynamics PD of epigoitrin,a main component in total alkaloids of Radix Isatidis,in yeast-induced febrile rats with the combined PK-PD model.Methods The plasma concentration of epigoitrin after ig administration with total alkaloids of Radix Isatidis was determined by HPLC method and the body temperature was recorded by electronic thermometer.The individual PK parameters were fitted using one compartmental model.The PD parameters were fitted by three kinds of PK-PD binding models,such as indirect inhibition-Kin model,indirect stimulation KoutPD model,and Sigmoid-Emax model.Results The main PK parameters t1/2,Cmax,AUC were(4.94?0.84) h,(4.01?0.21) ?g/mL,(28.37?2.42) ?g?h/mL and(5.71?0.91) h,(4.15?0.25) ?g/mL,(30.35?2.58) ?g?h/mL in both normal and febrile rats,respectively.The relationship between pharmacological effects and effect compartment concentration was better fitted with the indirect inhibition-Kin PD model.The corresponding PD parameters were Kin=(0.70?0.10) h-1,Kout=(0.54?0.12) h-1,R0=1.33?0.16,IC50=(0.94?0.66) mg/L.ConclusionThe PK parameters of epigoitrin in total alkaloids of Radix Isatidis show that there is no significant difference in PD behavior in vivo in both normal and febrile rats.Relationship between in vivo PK and PD of epigoitrin in febrile rats is established using indirect inhibition Kin model.
