Objective To evaluate the clinical effect ofXugu-Huoxue decoction combined with anatomical reduction and internal fixation with cannulated screws in patients with femoral neck fractures. Methods A total of 89 patients with femoral neck fractures were randomly divided into a control group and a Xugu-Huoxuegroup according to the random number table, with 46 in the control group and 45 in the Xugu-Huoxuegroup. The control group was treated with anatomical reduction and internal fixation with cannulated screws, while theXugu-Huoxuedecoction group was treated withXugu-Huoxuedecoction on the basis of the control group. The hemodynamics of the femoral vein was evaluated with color Doppler sonography. Hip function was rated with Harris hip score.ResultsAfter 12 months of treatment, the minimum diastolic velocity (12.0 ± 2.2 cm/svs.9.3 ± 2.0 cm/s;t=3.675,P<0.01), diameter (0.8 ± 0.3 cm vs. 0.6 ± 0.1 cm;t=3.675, P<0.01) and blood flow (1 123.4 ± 271.1 ml/minvs.901.2 ±121.1 ml/min;t=5.067,P<0.01) of the femoral vein in theXugu-Huoxuedecoction group were significantly increased than those in the control group. The rates of excellent or good in theXugu-Huoxuedecoction group and the control group was 86.7% (39/45) and 63.0% (29/46), respectively, with statistically significant difference (χ2=5.529,P=0.019). There were 2 patients (4.4%) with delayed fracture healing and 2 patients (4.4%) with femoral head necrosis in theXugu-Huoxuedecoction group, while 3 patients (6.5%) with delayed fracture healing, 5 patients (10.9%) with femoral head necrosis inthe control group, without statically significant difference (χ2value were 0.000, 0.572,P value were 1.000, 0.449, respectively).ConclusionXugu-Huoxue decoction combined with anatomical reduction and internal fixation with cannulated screwscan improve the fracture prognosis and the joint function in patients with femoral neck fractures.

Objective To evaluate the effect of alIoHCT on recurrence and metastasis of HCC after hepatic radical resection. Methods Umbilical cord blood were collected after labor. The efficacy of separa-tion by 6% hydroxyethyl starch (6% HES) and NH4CL lysing solution were examined. Twenty-two SCID mice were randomized into the scheduled transplantation group (n=8), the single transplantation group (n =8) and the normal saline group (n=6). Human nucleated cells (NC)at a amount of 5×107 were transfused through the tail vein into the 2 groups of transplantation. All the mice in the 3 groups received cyclophospha-mide (CTX) as conditioning regimen before tansplantation and Methylprednisolone (MP) for 1 week continu-ously after trasplantation. Hematopoietic and immune recovery, graft versus host disease (GVHD), engraft-ment and survival rate were observed after transplantation. Six weeks after alloHST, the orthotopic tumor model in SCID mice was established by implanting histologically intact tissue under the embrane of liver. Ten days later, the mice received radical resection of lobe bearing tumor. The condition of recurrence and metas-tasis was observed 4 weeks after operation. Results A murine model of umbilical cord blood transplantation using CTX and MP as conditioning regimen could be successfully established in SCID mice. The percentage CD34+ cells of peripheral blood NC in scheduled transplantation group and single transplantation group was 1.66%±0.47% and 0.68% + 0.56%, respectively. There was significant statistical significance (P<0.01). The intrahepatic recurrence rate after operation was 100% in all the 3 groups. However, the recur-rent tumor volume was (367.18±31.86) mm3 , (648.26±155.22) mm3, (811.38±127.36) mm3, re-spectively in the 3 groups. There was marked difference among the 3 groups (P<0.01). The inhibitory rate of group A and B was 54.7% and 20.1%. The incidence of lung metastasis was 14.3 (1/7), 6.7% (4/6) and 100% (5/5), respectively in the 3 groups and there was remarkable difference (P<0.01). The inci-dence of celiac lymph node metastasis was 14.3 (1/7), 33.4% (2/6) and 40% (2/5), respectively in the 3groups and there was no significant difference (P=0.58). Conclusion AlloHSCT is a useful method for de-creasing metastasis and recurrence of liver cancer after radical resection in early stage.

OBJECTIVE:To observe the clinical efficacy and safety of Qingjin huatan decoction for patients with AECOPD phlegm-heat obstructing lung. METHODS:120 patients with AECOPD phlegm-heat obstructing lung were divided into observation group and control group according to random number table,with 60 cases in each group. Control group received routine therapy as low-flow oxygen therapy,anti-infective,bronchiectasis,expectorant,etc.;observation group additionally received Qingjin huatan decoction(decocted by 400 ml pure water),tid,on the basis of control group. The levels of IL-8,IL-17,IL-23 and TNF-α were observed in 2 groups before and 7 d after treatment. Clinical efficacies and the occurrence of ADR were compared between 2 groups. RESULTS:Before treatment,there was no statistical significance in the levels of IL-8,IL-17,IL-23 and TNF-α between 2 groups (P>0.05). After treatment,the levels of IL-8,IL-17,IL-23 and TNF-α in observation group were significantly decreased and lower than in control group,with statistical significance (P<0.05). The levels of IL-17,IL-23 and TNF-α in control group were decreased significantly compared to before treatment,with statistical significance(P<0.05);the level of IL-8 had no signifi-cant change compared to before treatment,without statistical significance (P>0.05). Excellent rate of observation group was 95.00%,which was significantly higher than 78.95% of control group,with statistical significance(P<0.05). There was no statis-tical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Qingjin huatan decoction shows signifi-cant therapeutic efficacy in the treatment of AECOPD phlegm-heat obstructing lung,and can improve inflammatory factors with good safety.

Acute leukemia is the most common malignacy in children. Along with the development of medical science and the elevation of the level of diagnosis and treatment, most of the childhood leukemia is changed from "incurable disease"to "curable disease". But due to traditional concept? economic factors ?and lagging of social guarantee system,about 1/3～1/2 of patients's parents discontinue or give up treatment,which makes patients lose the medical rights and survival rights.We appeal medical workers and the whole society to devote love?to save the children from suffering leukemia,help the family and make society more harmonious.

Objective To study the expression of NM-23 ,PCNA,p53 and S-100 in colorectal cancer tissues and their relationship.Methods Three hundred and seventy eases of elderly eolorectal cancer were labelled with NM-23,PCNA,p53 and S-100 and staged by pTNM classification.Results The positive rates of NM-23,PCNA,p53 and S-100 were 74.9% ,60.3% ,58.1% ,68.1% respectively.In elderly group,the expression of NM-23 had a neg-ative correlation with that of PCNA (r = -0.101 ,P = 0.026).However the expression of NM-23 had a positive corre-lation with that of p53 (r =0.111 ,P =0.016 ),the expression of S-100 had a positive correlation with that of p53 (r=0.112,P = 0.015 ),the expression of S-100 had a positive correlation with that of PCNA (r =-0.229,P =0.000).Conclusions In the elderly patients,NM-23,p53 and S-100 were significantly correlated with the inva-sion,metastasis and prognosis of eoloreetal cancer.PCNA may be a stimulative factor in the invasion and metastasis of colorectal cancer.NM-23 ,PCNA,p53 and S-100 can serve as effective markers in reflecting the invasion,metas-tasis and prognosis of colorectal carcinoma in the elderly.

BACKGROUND:Nano-hydroxyapatite/polyamide artificial bone has good biocompatibility and strong tissue binding force, which exerts a significant role in the recovery of neurological function. OBJECTIVE: To investigate the clinical effect of nano-hydroxyapatite/polyamide artificial bone in anterior cervical fusion. METHODS: Ninety patients with cervical spondylosis and traumatic dislocation of the cervical spine were randomized into observation group and control group. Patients in the two groups underwent nano-hydroxyapatite/polyamide artificial bone and autologous iliac bone implantation, respectively. Surgical condition, Japanese Orthopaedic Association score, vertebral height loss and bone fusion rate were compared and analyzed at different time after implantation. RESULTS AND CONCLUSION:There were no significant differences in surgical time, out of bed time, postoperative hospitalization time between the two groups (P > 0.05), but the intraoperative blood loss was significantly lower in the observation group than the control group (P < 0.05). Japanese Orthopaedic Association scores were significantly increased in the two groups at 3 and 6 months after operation and at last folow-up than before (P < 0.05), but there was no difference in the Japanese Orthopaedic Association score between the two groups (P> 0.05). The vertebral height loss and bone fusion rate had no difference between the two groups at 6 months after operation and at the last folow-up (P > 0.05). No adverse effects occurred in the two groups. These findings indicate that nano-hydroxyapatite/polyamide artificial bone has good clinical effects in anterior cervical fusion, and the treatment effect is equivalent to autologous iliac bone graft.
