Objective:This study aimed to determine the function of herbs in preventing diarrhea after irinotecan chemotherapy and analyze the efficacy of the herbs based on UGT1A1*28 gene polymorphism. Methods:A total of 200 patients admitted to the De-partment of Synergistic Chinese and Western Medicine, Tianjin Medical University Cancer Institute and Hospital between October 2011 and May 2013 were randomly divided into the control (chemotherapy alone) and herb (chemotherapy combined with herbs) groups. All patients consented to UGT1A1*28 gene polymorphism detection prior to chemotherapy. Herbs were administered from 2 d prior to chemotherapy to 5 d post chemotherapy, with or without the regimen of fluorouracil, folinic acid, and irinotecan. Adverse reac-tions were recorded, and short-term effect was evaluated regularly. Results:A total of 144 patients had TA6/6 wild genotype, and anoth-er 56 patients had non-wild genotype (12 of the 56 cases were TA7/7 homozygous, and the other 44 cases were TA6/7 hybrid). A total of 58 patients experienced grades 2 to 4 diarrhea. A 14%decrease in the incidence of diarrhea was observed in the herb group compared with that of the control group (22%vs. 36%, P=0.029). In addition to diarrhea, grades 2 to 4 vomiting was significantly lower in the herb group than in the control group (15% vs. 27%, P=0.037). The overall response rate was 37.5%. No significant difference was found between the two groups (40% vs. 35%, P=0.465). The incidences of grades 2 to 4 diarrhea (22.9% vs. 44.6%, P=0.002) and grades 2 to 4 vomiting (23.2%vs. 16.7%, P=0.016) were lower in patients with the UGT1A1*28 wild genotype than in those with the non-wild genotype. However, in the herb group, the incidences of grades 2 to 4 diarrhea (22.2% vs. 21.9%, P=0.974) and vomiting (18.5% vs. 13.7%, P=0.777) were not significant between the non-wild-and wild-type groups. Conclusion:Herbs can effectively pre-vent the late diarrhea caused by irinotecan, which is also applicable in UGT1A1*28 non-wild genotype patients. Incidence of diarrhea was obviously higher in the cases with UGT1A1*28 non-wild type than in those with wild genotype. Hence, the UGT1A1*28 gene type should be detected prior to chemotherapy with irinotecan.

Objective To explore the influence factors of hidden blood loss during the treatment of femoral intertrochanteric fractures with percutaneous compression plate( PCCP) in elder patient. Methods The data of 136 patients with intertrochanteric fracture in our hos-pital from March 2009 to March 2012 treated with percutaneous compression plate were retrospectively analyzed,the effect of age,fracture type,preoperative aspirin,internal diseases on perioperative hidden blood loss, and different haemoglobin ( HGB) levels in patients with dif-ferent distribution were analyzed. Results The mean hidden blood loss volume was 499 mL,which accounted for 92. 54% of the total blood loss. The mean HGB decline was 11 g/L. The rate of on admisson haemoglobin level lower than 80 g/L was 6. 62% in AO type A2. 3 and A3 groups,and the rate of postoperative haemoglobin level lower than 80 g/L was 14. 70%. The average hidden blood loss for AO type A2. 3 (862 mL) and A3 (698 mL) were higher than those for AO types A1 (430 mL),A2. 1 (450 mL) and A2. 2 (415 mL) (P<0. 05). Multi-variate linear regression analysis showed that comminuted fracture and preoperative aspirin treatment were independently associated with in-creased perioperative hidden blood loss. Conclusion It indicated that the overt blood loss was fewer for PCCP operation. Intertrochanteric fracture was the main reason for substantial perioperative hidden blood loss. Types A2. 3 and A3 intertrochanteric fracture were early predic-tive factors of postoperative haemoglobin level lower than 80 g/L in elderly patients.

Objective To study the epidemiological characteristics of the hip fractures of the inpatients so as to provide a scientific basis for strategic study on the prevention and treatment of the hip fractures. Methods The study involved 448 patients (217 males and 231 females) with hip fractures admitted to the Southwest Hospital of Third Military Medical University from January 2004 to December 2009. The characteristics, injury time and causes, fracture types and treatment approaches were collected and reviewed retrospectively. SPSS 13.0 software was used for statistical analysis. Results There were significant differences in distribution of the hip fractures in terms of age, cause, gender and treatment approach (P < 0.05 ). Patients with age ≥60 years accounted for 68.8%. Slip was the leading cause of the hip fracture ( 69.6% ). As for gender distribution, femoral neck fractures usually occurred in the females while intertrochanteric hip fractures in the males. Surgery was the predominant management approaches,accounting for 83.1%. Conclusion The distribution of the hip fractures of the inpatients has unique characteristics in aspects of individual character, injury cause injury site and treatment approach, which is worthy of further strategic study on prevention and treatment of the hip fractures.

Objective To observe the osteogenic effect of tissue-engineered bone constructed by poly-L-lysine-demineralized bone matrix (PLL-DBM) enriched bone marrow stem cells in the space of goat transverse process bone fusion model and explore a new tissue-engineered bone construction method. Methods PLL was used to decorate goat DBM to prepare a matrix material (PLL-DBM). The osteo-genic effect of tissue-engineered bone constructed by PLL-DBM enriched bone marrow cells ( Group Ⅰ A) was detected in goat lumbar intertransverse graft bone model; autogenous iliac bone (Group Ⅰ B), DBM enriched bone marrow (Group Ⅱ C) and DBM (Group Ⅱ D) were used as controls. The osteogenesis of the bones in the fused segments of four groups were compared and evaluated by X-ray, three-dimensional CT, CT value testing and biomechanical testing. Results The results of X-ray showed that the fusion ranges in groups ⅠA and ⅠB were basically the same, which were significantly wider than that in Group Ⅱ, with no fusion detected in Group Ⅱ D. The CT value was (696.76±10275) HU in Group Ⅰ A and (766.03±69.24) HU in Group B, which were significantly higher than that in Group Ⅱ C (P <0.05), but there was no statistical difference in CT value between Groups Ⅰ A and Ⅰ B (P > 0.05). The CT val-ue in Group Ⅱ C was significantly higher than in Group ⅡD (P <0.01). There was no statistical differ-ence between Groups Ⅰ A and Ⅰ B in the maximum load and bending strength (P > 0.05). The maxi-mum load and bending strength in Groups Ⅰ A and Ⅰ B were significantly higher than that in Group Ⅱ C (P < 0.05), and the two indices in Group Ⅱ C were significantly higher than that in Group Ⅱ D (P <0.01). Conclusion Tissue-engineered bone constructed by PLL-DBM enriched bone marrow cells is an ideal tissue engineered bone and its osteogenic potential is similar to that of autologous bone.
