Objective To observe the preemptive analgesia effects of katamine and elonidine, and to find out the influence of preemptive on stress responses. Methods 36 patients with hysteromyoma undergone hysteromyomec-tomy were randomly assigned to three groups (n = 12 each group) :group Ⅰ , control group, without preemptive analge-sia,the patients in control group were given continous epidural analgesia with 2% lidoeaine 12 - 14ml. Group Ⅱ ,the patients were injected 0. 6mg/kg katamine into epidural analgesia 30 minutes before operation. Group Ⅲ,the patients were injected 0. 6mg/kg katamine and 1.5μg/kg clonidine into epidural analgesia 30 minutes before operation. The patients in three groups were recorded VAS score on 2h ,4h ,6h, 12h ,24h after operation, also recorded the change of epinephrine(E) and norepinephrine(NE) and sensation and movement recovery time after operation. The side effects such as dizziness nausea,vomit,and exited talking were observed during the operation. Results The VAS score were significantly different between group Ⅰ ,Ⅱ and Ⅲ. The levels of E and NE in plasma in group Ⅰ were increased more than group Ⅱ and Ⅲ within 24 hours after operation, also there is significant difference in group Ⅱ compared with group Ⅲ in T1 ,T2 ,T3. The time of sensation and movement recovery were remarkably longer in group Ⅲ com-pared with group Ⅰ and Ⅱ, showing significant difference. There were no significant difference in side effects after operation in three groups. Conclusion The preemptive analgesia of kutamine and colnidine can relieve the pain of lower abdominal surgery and stress response after operation,and it do not increase the side effects.

C-reactive protein(CRP)is the most sensitive indicator of acute phase proteins.A growing body of evidence suggests that atherosclerosis,as a main cause of cerebral infarction,is a chronic inflammtory process.The present studies have found that the CRP levels and genetic polymorphisms are associated with atherosclerosis and cerebral infarction.As compared with coronary artery disease,the association between high-sensitive CRP and ischemic stroke is more closely.This article reviews the advaces in research on the biological characteristics of CRP,the factors influencing CRP levels,the CRP levels and the correlation between genetic polymorphisms and cerebral infarction.

Colorectal cancer(CRC)ranks the third in incidence and mortality rate among human tumors. Tumor relapse,me?tastasis and drug resistance remain the main obstacle to the success of CRC treatments. Compared to traditional chemotherapy ,target therapy seems to treat tumors in more precise and rational fashion with good response and often less toxic side-effect. Although target agents provide hope for more effective therapy,recent clinical studies have shown only modest benefit from target therapy similar to tra?ditional chemotherapy. Primary and secondary resistance to target agents is still observed and contributes to CRC treatment failure. The review summarizes research progress in the mechanism of drug resistance to target therapy in CRC treatment.

Objective To investigate the effect of dynamic regulation of negative pressure values in vacuum sealing drainage (VSD) on healing of soft tissue wounds.Methods From January 2013 to December 2015,115 patients were treated at our institute for open soft tissue defects of Gustilo-Anderson type ⅢaⅢc.They were 69 males and 46 females,aged from 17 to 76 years (average,44.7 years).They were divided into 4 groups to be subjected to different negative pressure values.Group A (n =29) was subjected to negative pressure values from-40 to-20 kPa,group B (n =29) to values from-80 to-60 kPa,group C (n =29) to values from-40 to-20 kPa for the first 72 hours followed by values from-80 to-60 kPa,and group D (n =28) to values from-60 to-80 kPa for the first 72 hours followed by values from-40 to -20 kPa.The 4 groups were compared in terms of drainage volume,wound shrinking,cleaning time,healing time and complications.Results The drainage volumes on the 7th day in groups B and D (4.89 ± 0.66 mL/cm2 and 4.33 ± 0.96 mL/cm2) were significantly higher than those in groups A and C (2.90 ± 0.67 mL/cm2 and 2.99 ±0.56 mL/cm2);the wound shrinking areas on the 14th day in groups B and D (14.16 ± 1.77 cm2 and 13.84 ± 1.65 cm2) were significantly larger than in groups A and C (12.57 ± 1.92 cm2 and 10.95 ± 1.37 cm2) (P ＜ 0.05).The cleaning time in group A was significantly longer than in the other 3 groups (P ＜ 0.05).The healing time in groups A and C was longer than in groups B and D (P ＜ 0.05).The incidences of pain in groups B and C were significantly higher than in groups A and D (P ＜ 0.05).The incidences of infection and blocking in group A were higher than in the other 3 groups (P ＜ 0.05).Conclusion Dynamic regulation of negative pressure values from-80 to-60 kPa for the first 72 hours followed by values from-40 to-20 kPa is an optimal choice for VSD management of soft tissue defects due to adequate drainage,obvious wound shrinking,quick cleaning and healing,and limited complications.

Objective To investigate the level of soluble interleukin 7 receptor (sIL-7R) in serum of lupus nephritis(LN)patients and evaluate its clinical significance. Methods sIL-7R level in serum of LN patients and healthy controls were measured by ELISA , while total 24 hours urinary protein and complement C3 of LN patients were measured by BN ProSpec. The level of sIL-7R correlation with SLEDAI, total 24 hours urinary protein and complement C3 were analyzed respectively. Results The levelof sIL-7R was higher in serum of LN patients than healthy controls (P < 0.01). Moreover, its expression in serum was increased in LN patients in active stage than in LN patients in stable stage (P < 0.05). The level of sIL-7R was positively assosicated with SLEDAI, total 24 hours urinary protein(P < 0.01, P < 0.05) and negatively with complement C3 (P < 0.05). Conclusion The level of sIL-7R is upregulated in serum in LN patients and correlated with disease activity and progression, so it may be expected to become a potential marker of disease in prediction.

Objective: To assess the activity of cathepsin D (CAT-D) and alpha-1 antitrypsin (AAT) in blood in patients with hip or knee osteoarthritis, and to explore whether these two enzymes could be served as serum biomarkers for cartilage degeneration. Methods: hTe activity of CAT-D and AAT in blood serum of 44 women and 26 men with hip or knee osteoarthritis was determined by the method of ELISA before total joint replacement and on the 10th day atfer the surgery. One hundred healthy volunteers were chosen as the control. All datawere analyzed by using SPSS19.0 sotfware. Results: Compared with the controls, the activity of CAT-D in patients with osteoarthritis was decreased by 25% (P<0.05) and 50% (P<0.05) before and atfer the surgery, respectively. hTe activity of AAT in the osteoarthritis patients before the surgery was not signiifcantly changed compared with the control group (P>0.05), but it was increased by 80% after the surgery than that in the control group (P<0.05). hTere was no signiifcant difference in the activities of 2 enzymes between hip and knee osteoarthritis (P>0.05). hTe gender, hypertension, diabetes and age did not affect the activities of the 2 enzymes (P>0.05). Conclusion: AAT might be a possible inflammatory indicator in the osteoarthritis. CAT-D and AAT enzymes are not affected by gender, age, hypertension and diabetes, etc, and they might be served as potential biomarkers for cartilage degradation.

Objective To investigate the characteristics and risk factors of the cerebral artery atherosclerotic stenosis in patients aged 90 years and older. Methods A total of 92 patients,aged 90 years or older,admitted to our hospital from July 2009 to July 2014 were respec-tively enrolled in this study. All participants underwent CTA to assess the presence and severity of atherosclerotic stenosis with intracranial and extracranial cerebral artery. The association between atherosclerotic stenosis and related risk factors were analyzed. Results The preva-lence of cerebral artery atherosclerotic stenosis was high in the cohort. The frequency of stenosis with intracranial artery was higher than the frequency with extracranial artery (86. 2% vs 44. 8%). The most common positions of cerebral artery atherosclerotic stenosis were the middle cerebral artery (43. 1%),the posterior cerebral artery (43. 1%),and extracranial vertebral artery (32. 8%). The mean age,body mass in-dex,systolic and diastolic blood pressure,and fasting blood glucose of stenosis group are significantly different from the non-stenosis group in single factor analysis (P<0. 05). Multivariate Logistic regression analysis showed body mass index was the independent risk factor of cere-bral artery atherosclerotic stenosis(β=1. 326,OR=3. 765,P<0. 05). Conclusion The prevalence of cerebral artery atherosclerotic steno-sis was high in the patients aged 90 years and older. Body mass index was the independent risk factor. The weight control should be pay atten-tion to prevent cerebral artery atherosclerotic stenosis and stroke.

Objective To explore changes of expression of pro-and anti-inflammatory cytokines in the hippocam-pus of Aβ1-42-induced Alzheimer’s disease (AD) rat model. Methods Twenty-four SD rats were divided into control group, PBS group (PBS was injected into CA1 area of hippocampus) and AD model group (Aβ1-42 was injected into CA1 area of hip-pocampus). The escape latency was evaluated by Morris water maze in three groups. Nissl staining was used to detect the le-sions of hippocampal CA1 neurons. Levels of amyloid precursor protein (APP) and protein phosphatase 2A (PP2A) in hippo-campus were measured by Western blot analysis. Real-time PCR was employed to examine the expressions of pro-inflamma-tory cytokines, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ), and the mRNA expressions of anti-inflammatory cytokines, including IL-4, IL-10 and transforming growth factor-β(TGF-β). Re-sults Rats subjected to Aβ1-42 injection in bilateral hippocampus led to a ability reduction of learning and memory, a loss of neurons in hippocampus and an increase in the expression of APP, and a decrease in PP2A expression in the hippocampus. In AD hippocampus, The mRNA expressions of the pro-inflammatory mediator, IL-1β, TNF-αand IFN-γ, were significant-ly up-regulated, but the expressions of the anti-inflammatory cytokines, IL-4, IL-10 and TGF-β, were markedly down-reg-ulated in AD group compared with those of control and PBS groups. Conclusion The pro-inflammatory/anti-inflammatory imbalance induced neuro-inflammation in AD rats, which was involved in pathogenesis of AD.
