Objective To evaluate the statues of P-selectin and chang of D-dimer in vivo in patients with deep venous thrombosis(DVT)and to observe how to vary under interneving of medicines.Methods P-selectin and D-dimer of fourty patients and twenty normal subjects were fluo-rescencelabled with its corresponding monoclonal antibodies by flow cytometry(FCM)and immune method respectively.Results In the early stage,P-selectin and D-dimer of patients with DVT is higher than that in normals,and they significantly decreased in different time after patients were treated.Compared with patients who were used on-sodium ozagrel,patients used sodium ozagrel have different P-selectin(P＜0.05),but D-dimer was similar(P＞0.05)after fourteen days.One month later,P-selectin and D-dimer of DVT patients were lower.However,the positive rate of P-selectin of DVT was still higher than normal subjects.Conclusions The platelet has been actived in vivo in patients with DVT,so do fibrinolysis.Sodium ozagrel can decrease the action of platelet.P-selectin and D-dimmer may be used in diagnose.Post-discharge patients are still high-risk group and must be followed-up regularly.

Objective To observe the treatment of continuous passive motion(CPM) on talipes valgus in the chil-dren with cerebral palsy. Methods There were 57 children in this research including normal group and valgus group, the children in valgus group were randomly divided into control group, non-CPM group and CPM group. The control group didn’t receive any rehabilitation treatment. The non-CPM group received conventional rehabilita-tion treatment. The CPM group received conventional rehabilitation and CPM therapy. Evaluate the children in nor-mal group with plantar pressure analysis and evaluate each patient before treatment two and four months after treat-ment with plantar pressure analysis. Results Compared with the normal group, the percentage of medial midfoot (MMF) pressure, HEEL pressure, initial contact phase(ICP) and forefoot contact phase(FFCP) were obviously higher in valgus groups. On the other hand, the percentage of lateral forefoot ( LFF) pressure, lateral midfoot (LMF) pressure and foot flat phase(FFP) were obviously lower in valgus groups(P < 0. 05). The percentage of MMF pressure, and FFP became lower after treatment in both CPM group and non-CPM group while the percentage of ICP and FFCP became higher(P < 0. 05). In CPM group there was a more obvious change with the percentage of MMF pressure, ICP and FFCP compared with non-CPM group and the control group(P < 0. 05). Conclusion U-sing CPM can alleviate muscle spasms and contracture, correct the deformity of midfoot, enhance the muscle group coordination on foot and further more improve gait of patients with cerebral palsy.

Objective The study aimed to evaluate the incidence rate and risk factors of early post-mastectomy pain syndrome (EPMPS) after surgery for breast cancer.Methods A retrospective study was carried out in 231 female patients with breast cancer who appeared EPMPS after surgery in the First Hospital of China Medical University from September 2012 to September 2014.They were followed-up for 3 months.Results Among 231 female patients with breast cancer,41.1％ (95/231) suffered from EPMPS.The incidence of EPMPS in women of 40-59 years old was 66.3％ (63/95),significantly higher than other age groups,RR=l.83,P＜0.05.Those who were submitted to axillary lymph node dissection and those without preservation of intercostobrachial nerve had shown a significantly increased risk of EPMPS compared with those with sentinel lymph node biopsy plus no surgery and preservation of intercostobrachial nerve patients (81 cases vs.14 cases,41 cases vs.18 cases,x2=19.921,P＜0.01;x2=11.045,P＜0.05).Conclusions The frequency of EPMPS in the middle-age women is high and possible explanations are unclear.Surgery of axilla affects the incidence of EPMPS,reassurance is key to coping with EPMPS in nursing and rehabilitation.

controlling nutritional status (CONUT) after radical resection of colorectal cancer.Methods The clinical data of 180 patients who underwent radical resection of colorectal cancer at the Tumor Hospital of Xinjiang Medical University between June 2012 and June 2014 were retrospectively analyzed.Seventy patients with scores of NRS 2002 ≥ 3 were allocated into the A group including 40 with enteral nutritional support therapy in the A1 group and 30 without enteral nutritional support therapy in the A2 group, 60 patients with scores of NRS 2002 ＜ 3 and negative CONUT was allocated into the B group including 30 with enteral nutritional support therapy in the B1 group and 30 without enteral nutritional support therapy in the B2 group, 50 patients with scores of NRS 2002 ＜ 3 and positive CONUT was allocated into the C group including 25 with enteral nutritional support therapy in the Cl group and 25 without enteral nutritional support therapy in the C2 group.The nutritional status of patients was evaluated using a joint of NRS 2002 and CONUT.There was nutritional risk in patients with scores of NRS 2002≥3 or scores of NRS 2002 ＜ 3 and positive CONUT and no nutritional risk in patients with scores of NRS 2002 ＜ 3 and negative CONUT.Patients and their families would choose whether or not to undergo enteral nutritional support therapy after the risks being informed.Enteral nutritional support therapy included tube feeding enteral nutrition or oral nutriments with calories ≥41.84 k J/(kg · d) for more than 3 days.Observed indicators: (l)Nutritional indicators included fasting serum albumin (Alb), prealbumin and transferrin before operation, at postoperative day 1 and day 7.(2)Postoperative recovery included time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay.Measurement data with normal distribution were presented as x ± s, comparison among groups was analyzed using the t test and repeated measures

differences in the changing trends of the above 3 indicators between the 2 groups (F =5.625, 4.225, 8.221, P ＜0.05).Postoperative recovery: time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay were (1.9 ± 0.5) days, (2.3 ± 0.5) days, (8.6 ± 1.2) days, (14.7 ± 1.1) days in the A1 group and (3.0 ± 0.5) days, (4.5 ± 0.6) days, (11.4 ± 2.2) days, (17.8 ± 1.3) days in the A2 group, respectively,with significant differences between the 2 groups (t =-0.644,-12.200,-8.710,-11.650, P ＜ 0.05).Time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay were (1.2 ± 0.3)days, (3.2 ±0.7)days, (10.3 ± 1.4)days, (14.7 ±2.0)days in the B1 group and (1.5 ±0.5)days, (3.7 ± 0.6) days, (11.0 ± 1.2) days, (16.1 ± 1.5) days in the B2 group, respectively, with no significant difference between the 2 groups (t =-1.929,-1.033,-1.019,-1.171, P ＞0.05).Time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay were (1.8 ± 0.7) days, (2.1 ± 0.5) days,(7.6±1.2)days, (13.9 ±1.2)days in the C1 group and (3.1 ±0.5)days, (4.5 ±0.7)days, (11.4±2.4)days,(17.6 ± 1.3) days in the C2 group, respectively, with significant differences between the 2 groups (t =-5.934,-10.950,-10.010,-11.700, P ＜ 0.05).Conclusions A joint application of NRS2002 and CONUT after radical resection of colorectal cancer is exact and feasible for evaluating nutritional status of patients and guiding enteral nutritional support therapy.Patients should select nutritional support therapy after operation if there is nutritional risk.The proper nutritional support therapy can improve the postoperative nutritional status of patients with colorectal cancer, enhance the postoperative recovery and reduce the duration of hospital stay.

Objective To investigate the levels of inflammatory cytokines in children with low absolute lymphocyte count (ALC).Methods 56 patients with low ALC as the patients group and 20 children with healthy physical examination as the control group were enrolled.Several inflammatory cytokines,namely IL-1,IL-6,IL-8 and TNF-βwere measured with enzyme linked immu-nosorbent assay(ELISA)kits.High sensitive C reactive protein(Hs-CRP)was measured by the immunoturbidimetry(ITM)kit with the automatic biochemical analyzer.Results The concentrations of IL-1,IL-6,IL-8 and TNF-βin the patients were(0.096±0.012) ng/mL,(0.118±0.026)ng/mL,(0.388 ±0.069)ng/mL and(1.256 ±0.245 )ng/mL respectively,which had no statistical differ-ences as compared with the control group(P >0.05);the concentration of HsCRP in the patients group was(5.7±2.8)mg/L,while which in the control group was(4.8±2.6)mg/L,showing no statistically significant difference between them(P >0.05).Conclusion The levels of the cytokines in low ALC patients are not increased,which may be related with the other factors.Actively using tra-ditional Chinese medicine treatment is beneficial to the recovery of disease.
