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 .

Currently all military hospitals attach great importance to the management of state-owned assets.However,there still exist some problems,such as weak management consciousness,irregular assets disposing and loose connections between management and accounting.The author ventures some measures to strengthen management consciousness,organization establishment,accounting procedures and monitoring mechanism.

Objective To investigate the effects of sevoflurane preconditioning on autophagy after traumatic brain injury (TBI) in rats and the role of C-Jun N-terminal kinase (JNK) signaling pathway.Methods Sixty adult male Sprague-Dawley rats,weighing 220-250 g,were randomly divided into 4 groups (n =15 each) using a random number table:sham operation group (group S),group TBI,TBI + sevoflurane preconditioning group (group TBI + Sevo) and TBI + sevoflurane preconditioning + JNK inhibitor SP600125 group (group TBI + Sev + SP).TBI models were established using Feeney' s method.In TBI + Sev and TBI + Sev + SP groups,the rats inhaled 2.4％ sevoflurane for 30 min once a day for 4 concecutive days,and TBI was produced at 24 h after the end of sevoflurane preconditioning.In TBI + Sev + SP group,SP600125 (6 mg/kg) was injected intrapetitoneally at 30 min after TBI.Five rats were chosen at day 1,3,and 7 after TBI,and neurological deficit score (NDS) was measured.The rats were then sacrificed and brains were removed to measure brain water content,expression of LC3 lⅡ and Beclin-1 mRNA (using PCR),and expression of LC3 Ⅱ,Beclin-1,JNK and phosphorylated JNK (p-JNK) (by Western blot).Results Compared with group S,brain water content and NDS were significantly increased,and the expression of LC3 Ⅱ and Beclin-1 protein and mRNA,JNK,and p-JNK was up-regulated in the other three groups.Brain water content and NDS were significantly decreased,and the expression of LC3 Ⅱ and Beclin-1 protein and mRNA,JNK,and p-JNK was down-regulated in TBI + Sev and TBI + Sev + SP groups as compared with group TBI,and in TBI + Sev + SP group as compared with TBI + Sev group.Conclusion The mechanism by which sevoflurane preconditioning mitigates TBI is related to inhibiton of activation of JNK signaling pathway and decreased autophagy in rats.

Objective:To compare the clinical efficacy and safety of nalmefene hydrochloride injections and Naofukang injections in the treatment of the patients with severe head injury. Methods:Totally 60 cases of patients with severe head injury were randomly divided into the observation group and the control group. The two groups were all given the conventional therapy, such as dehydration, expansion and anti-infective therapy. On the basis of the conventional therapy, the observation group was treated with nalmefene hydro-chloride injections, 0. 4-0. 6 mg in 0. 9% sodium chloride injections, ivd, qd, while the control group was given Naofukang injections, 4-9 g in 5% or 10% glucose injections, ivd, qd. The treatment course was 2 weeks. After the 3-day treatment, the heart rhythm, the incidence of respiratory abnormalities and intracranial pressure were compared between the two groups. After the 10-day treatment, the total efficacy and complications in the two groups were also recorded and compared. Results:After the 3-day treatment, the incidence of abnormal heart rhythm and respiratory abnormalities in the observation group were significantly lower than that in the control group (P<0. 05), the intracranial pressure in the observation group was better than that in the control group (P<0. 05). After the 10-day treatment, the total effective rate of the observation group was 93. 3%, which was much higher than that in the control group ( P<0. 05). After the treatment, the incidence of respiratory infections, acid-base unbalance and upper gastrointestinal bleeding in the ob-servation group was significantly lower than that in the control group (P <0.05). Conclusion: The clinical efficacy of nalmefene hydrochloride injections in the treatment of patients with severe traumatic brain injury is significant with promising safety, which is bet-ter than that of Naofukang injections.

Objective:To evaluate arthroscopy-assisted tibial bone tunnel fixation combined with double-row anchors in the treatment of tibial eminence fracture.Methods:The 23 patients were retrospectively analyzed who had been treated at Department of Orthopedics, Beiing Shunyi District Hospital for tibial eminence fractures by arthroscopy-assisted tibial bone tunnel fixation combined with double-row anchors from October 2015 to December 2019. They were 15 males and 8 females, aged from 12 to 55 years (average, 35.5 years). All the injuries were unilateral (14 right and 9 left sides). According to the modified Meyers-McKeever classification, 2 cases belonged to type Ⅱ, 18 cases to type Ⅲ and 3 cases to type Ⅳ. Range of motion of the knee, Lysholm and International Knee Documentation Committee (IKDC) scores were observed before surgery, 1 month and 12 months after surgery. The anterior tibial slope angle (ATSA) on CT was measured preoperatively and 1 month after surgery for evaluation of fracture reduction.Results:All the 23 patients were followed up for an average of 23 months (from 12 to 52 months). Postoperatively, limited knee movement was observed in 2 patients and non-anatomic reduction in one patient. At 1 month and 12 months after operation, the Lysholm scores (61.4 ± 3.5 and 90.4 ± 4.3) and IKDC scores (69.6 ± 4.2 and 88.5 ± 3.0) were significantly improved compared with the preoperative values (45.4 ± 6.8 and 49.6 ± 3.9, respectively) ( P<0.05). ATSA was significantly restored from preoperative 4.2° ± 5.7° to -11.7° ± 2.9° at 1 month after operation ( P<0.05). Conclusion:In the treatment of tibial eminence fracture, arthroscopy-assisted tibial bone tunnel fixation combined with double-row anchors can achieve anatomical reduction and firm fixation, leading to satisfactory surgical outcomes.

Background and purpose:The role of urine N-telopeptides of type Ⅰ collagen(uNTX) and serum bone spesifi c alkaline phosphatase(sBAP)was confi rmed in osseous metastasis of solid tumors. The aim of this article was to study their role in multiple myeloma (MM). Methods:Thirty eight MM patients (22 new diagnosed, 12 relapsed or refractory, 4 plateau patients ) were examined. Ten age-matched healthy volunteers were used as controls. Urine and serum samples were taken from all patients and controls before therapy, after 3 months and 6 months chemotherapy. Urine samples of NTX, serum samples of BAP were measured with enzyme-linked immunosorbent assays (ELISA). Results:Urine NTX concentrations were signifi cantly higher in newly diagnosed and relapsed or refractory patients than that in plateau patients and controls. Serum BAP concentrations were signifi cantly lower than that in plateau patients and controls. In newly diagnosed patients, urine NTX values were signifi cantly higher in stage Ⅲ disease than in stage Ⅰ/Ⅱdisease, serum BAP values were signifi cantly higher in stage Ⅰ/Ⅱ disease than stage Ⅲ disease. At the third month, urine NTX were signifi cantly lower and serum BAP were signifi cantly higher as well as at the sixth month. But osteolytic lesions in X–ray had no change at the sixth month. Conclusions:Bone turnover markers uNTX, sBAP and bone destruction are closely interrelated in multiple myeloma, they change much earlier than X-ray. They are useful in monitoring progression and the therapeutic effect of myeloma.

Objective To explore the relationship of stromal derived factor 1α (SDF-1α) and CD44variant isoforms (CD44v6) with progress of multiple myeloma (MM). Methods Bone marrow mononuclear cells(MNCs) and bone marrow stromal cells (BMSCs) from 24 cases of MM patients (14 cases of untreated and relapsed and 10 cases of stable MM patients) and 15 cases of subjects were investigated as potential SDF-1αand CD44v6 product. The level of SDF-1α and CD44v6 of the conditioned media from MM patients and subjects were analyzed by ELISA. Results The level of SDF-1α and CD44v6 from MNCs in untreated and relapsed MM patients [(7232.41 ± 2644.97) pg/ml and (34.34 ± 13.20) ng/ml] were significantly higher than stable MM patients [(2315.49 ± 748.29) pg/ml and (15.69 ± 5.28) ng/ml] (t =6.25, t= 7.82, P ＜0.05) and 15 subjects [(1149.52 ± 636.06) pg/ml and (4.85 ± 3.62) ng/ml] (t= 4.60, t = 7.61, P＜ 0.05). The level of SDF-1α in stable MM patients was different from healthy subjects (P ＜0.05), but the level of CD44v6 in stable MM patients was not different from controls. The level of SDF-1α and CD44v6 in stable MM patients were significantly higher than health subjects (t = 2.99, t= 4.87, P ＜0.05). The level of SDF-1α was also detected from BMSCs of MM patients. When human MM cell lines U266 were adhered to BMSCs of 9 untreated and relapsed MM patients,and added rhIL-6 to it, there was significant increase of SDF-1α, compared with BMSCs in subjects and MM patients. The expression level of SDF-lα was correlated with the level of CD44v6 (r =0.51, P =0.03). Conclusion The increase of SDF-1α (may be produced by myeloma cells and BMSCs) and CD44v6 (may be produced by myeloma cells) activity is associated with the progress or pathogenesis of MM, and may be involved with tumor invasion. The completion of these processes in vivo may need participation of myeloma cells, BMSCs, IL-6,SDF-lα and CD44v6.

Objective To evaluate the changes of endometrial microcirculation between pre-and postmenopause with magnetic resonance dynamic contrast-enhanced perfusion weighted imaging (MR DCE-PWI)and intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI).Methods Thirty-three patients with normal endometrium (premenopause in 21 and postmenopause in 12)confirmed by pathology underwent DCE-PWI,IVIM-DWI and conventional MRI.Quantitative parameters of DCE-PWI and IVIM-DWI in the endometrium were analyzed and compared between pre-and postmenopause groups.Results The DCE-PWI parameters were significantly higher in premenopause group than those in postmenopause one with significant differences in Ktrans (0.161±0.081)min-1 vs (0.097±0.054)min-1 , Kep (0.285±0.145)min-1 vs (0.184±0.119)min-1 and IAUC60 (20.854±10.695)mmol·kg-1 ·s vs (10.481±6.253)mmol·kg-1 ·s. No significant differences were found between the two groups in IVIM-DWI parameters including D,D* and f values.Conclusion DCE-PWI,rather than IVIM-DWI,can be used to quantitatively evaluate the changes of endometrial microcirculation between pre-and postmenopause.
