0.05).The stimulative index(SI)tested by MTT in MLR at stimulator-to-reactor cell ratio 1∶1,1∶10,1∶20,1∶40 and 1∶80 was 2.7,4.1,3.1,2.5 and 1.6,respectively.The proliferation of T cells stimulated by DCs could be detected at all stimulator-to-reactor ratio.Conclusion DCs could be successfully induced from peripheral blood monocyte in the patients with colorectal cancer by AIM-V serum-free media or by traditional FBS-contained media.AIM-V is more suitable for clinical immunotherapy because it can avoid the risk of allergic reaction for clinical purpose.AIM-V might take the place of serum-contained media to culture DCs.According to the results of MLR,DCs could stimulate allogenetic T cells proliferation at all stimulator-to-effector ratio,furthmore the optimal ratio is 1∶10 .

Objective To investigate the therapeutic effects of citalopram on alleviating painful symptoms in type 2 diabetes mellitus(DM) patients with complication of painful peripheral neuropathy.Methods Thirty-eight type 2 DM patients with painful peripheral neuropathy were randomly divided into control group(eighteen patients) and treatment group(twenty patients).The diabetes control(including fasting blood glucose) and general health state(including body mass index,liver function,renal function) of patients were recorded.Patients in control group were given conventional drugs(including hypoglycemic drugs,anodyne,neurotrophy drugs,antiplatelet drugs),and those in treatment group received conventional drugs plus antidepressant drugs(citalopram,20mg,q.i.d.for 14 days).Hamilton Depression Rating Scale for Depression(HAMD-17) was used to assess the depressive symptoms,and numeric pain intensity scale(NPIS) was used to assess the pain intensity on baseline and the 1st,7th and 14th day.At the same time,the levels of analgesic agents were recorded.Results On the 7th and 14th day,the HAMD-17 scores in treatment group(22.14?8.92,18.69?9.4) were significantly lowered compared with that in control group(26.81?9.79,25.71?9.92),P

Objective To explore the clinical value of lymphocyte sub-population and NK levels in patients with primary lung malignant tumor and patients with chronic obstructive pulmonary disease (COPD). Methods The percentage of CD3 +,CD4 +, CD8 +, CD19 + and NK cells were measured in 60 COPD patients and 50 primary lung malignant tumor patients and 40 normal control subjects using alkaline phosphatase antialkaline phosphatase (APAAP) assay, and CD4 +/CD8 + ratio was calculated. Results The levels of CD3 +,CD4 +,CD4 +/CD8 + and CD19 + cells were significantly lower in the patients with primary lung malignant tumor or COPD than those in the normal control subjects, which CD8 level was significantly higher (P0.05). No difference in the levels of CD3 +, CD4 + and CD8 + cells was found between the primary lung malignant tumor and COPD patients, but NK and CD19 + cells levels had significant difference(P

An adult patient with hypophosphatasia caused by compound heterozygous mutations in alkaline phosphatase,liver /bone /kidney(ALPL)gene was investigated through comprehensively reviewing the medical history and clinical records of the proband and her family members in order to better understand the disease.The proband and her older sister had mild decreased serum alkaline phosphatase level accompanied with frequently nontraumatic fractures at limbs and all the teeth fell off at the age of 20 and 7, respectively.Both of them carried a missense mutation c.407G>A(p.Arg136His)in exon 5 and a deletion mutation c.1318_1320delAAC(p.Asn440del)in exon 12 simultaneously.Other four family members were p.Arg136His mutation carriers and two members were p.Asn440del mutation carriers.We found that p.Asn440del mutation was associated with the oral disorders.In this family, compound heterozygous manifested more serious symptoms, while heterozygous showed relatively mild symptoms.In addition, it is necessary to differentiate it from primary osteoporosis and other diseases of disturbed bone mineralization.

BACKGROUND:Bipolar femoral head prosthesis has achieved the desired repair effect in patients with femoral neck fracture, but there is stil much controversy on the biomechanical properties of bipolar artificial femoral head prosthesis. OBJECTIVE:To compare biomechanical properties of the bipolar femoral head prosthesis replacement and internal fixation in the repair of femoral neck fracture in the elderly. METHODS:Twenty-three (46 sides) senile femoral neck fracture specimens were analyzed and randomized into internal fixation group(n=23)and bipolar femoral head prosthesis replacement group (n=23). Specimens in the internal fixation group underwent conventional metal implant fixation. Specimens in the bipolar femoral head prosthesis replacement group underwent bipolar femoral head prosthesis replacement. Mechanical properties of femoral prosthesis stem were tested on universal testing machine. Biomechanical properties after bipolar femoral head prosthesis replacement and internal fixation were compared. RESULTS AND CONCLUSION:(1) The maximum loadwassignificantly higher in the bipolar femoral head prosthesis replacement group than in the internal fixation group (P< 0.05). The maximum load trend images showed that the maximum load was significantly higher in the bipolar femoral head prosthesis replacement group than in the internal fixation group (P< 0.05). (2) The displacement in axial pul test was significantly shorter in the bipolar femoral head prosthesis replacement group than in theinternal fixation group (P< 0.05). The displacement trend images exhibited that the displacement in axial pul test was significantly shorter in the bipolar femoral head prosthesis replacement group than in the internal fixation group (P< 0.05). (3) These findings suggest that compared with the implant, bipolar femoral head prosthesis replacement in the repair of femoral neck fracture in the elderly is more stable, has better repair effects, can elevate hip function and obtain good initial stability.

Objective:This work aims to explore the long-term efficacy and complications of late-course accelerated hyperfrac-tionation (LCAHF) for treating nasopharyngeal carcinoma. Methods:A total of 58 patients who consulted from December 2005 to May 2008 and histologically proven nasopharyngeal carcinoma at initial diagnosis were randomized into an LCAHF group (experimental group) and a conventional fractionation (CF) group (control group). The treatment dose for both groups was 2 Gy per fraction once dai-ly, 5 days a week. After the 40 Gy to 50 Gy dose, the dosage in the LCAHF group was increased to two daily doses at 1.5 Gy per frac-tion 6 h apart, 5 days a week. The total dose in this group was 73 Gy to 76 Gy, the total dose in the CF group was 70 Gy to 76 Gy, with the total course of the treatment shortened by 0.5 weeks to 1.5 weeks in the former group. Results:The 5-year control rates of the naso-pharyngeal cancers was 86% in the LCAHF group and 59% in the CF group (P=0.021), with statistically significant differences be-tween the two groups. The late complications slightly increased in the LCAHF group than in the CF group, but the differences were not statistically significant. Conclusion:LCAHF treatment improves the local control of nasopharyngeal carcinoma without increasing the incidence of long-term complications.

Objective In view of the schizophrenia risk factors during the recovery,to explore a supportive intervention program suitable for the rehabilitative schizophrenic patients.Methods Totally 64 rehabilitative schizophrenic patients were divided into the experimental group and the control group with 32 cases in each group.All the patients received the same treatment with antipsychotic drugs.The patients in the control group received the routine health education.In addition,the patients in the experimental group received supportive intervention for 4 months.The patients were assessed by IBS,APGAR,GSES and SDSS before and after intervention.Results Main effect of group factor and time factor of GSES,SDSS,APGAR and IBS had statistical significances.There were significant interaction in the scores of SDSS,APGAR and IBS.Simple effect analysis demonstrated the scores of GSES,SDSS,APGAR and IBS in the experimental group were higher than those of the control group after the intervention.Except the score of GSES,there was no differences in other scales before and after the intervention of the control group.Conclusions Supportive intervention program for the rehabilitative schizophrenic patients have good practice guidance.It can improve the patients' self-efficacy,family function and social function,also can correct irrational beliefs and to help patients better adapt to society.
