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 evaluate the effect of alveolar recruitment maneuver on the perioperative pulmonary function in the morbidly obese patients undergoing laparoscopic sleeve gastrectomy.Methods Forty morbidly obese patients of both sexes,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 18-64 yr,with body mass index ≥ 40 kg/m2,scheduled for elective laparoscopic sleeve gastrectomy,were randomly divided into either control group (group C) or alveolar recruitment maneuver group (group R) using a random number table,with 20 patients in each group.Patients in group C were treated with volume-or pressure-controlled ventilation after creation of pneumoperitoneum,maintaining the peak inspiratory pressure (Ppeak) ≤ 30 cmH2O and partial pressure of end-tidal CO2 35-40 mmHg.Patients in group R received alveolar recruitment maneuver once every 30 min starting from creation of pneumoperitoneum until the end of surgery.Patients were transfered to post-anesthesia care unit (PACU) with endotracheal tube which was extubated when the unified extubation standard was achieved in PACU.The patients who stayed in PACU for 2 h showing no indications for extubation were transfered to intensive care unit for continuous ventilation support.Immediately after intubation,immediately after creation of pneumoperitoneum,at 30,60 and 90 min of pneumoperitoneum,and at the end of pneumoperitoneum,blood samples were collected from the radial artery for blood gas analysis.Immediately after intubation,immediately after creation of pneumoperitoneum,at 30,60 and 90 min of pneumoperitoneum,at the end of surgery,and immediately before discharge from PACU,Ppeak,plateau pressure (Peat),and dynamic lung compliance were recorded.The time for achieving extubation standard and time for achieving the standard for discharge from PACU were recorded.Patients were followed up until discharge,and the feeding time and duration of hospital stay were recorded.Results Compared with group C,PaO2 and oxygenation index were significantly increased at 90 min of pneumoperitoneum,at the end of surgery,and immediately before discharge from PACU,Ppeak was decreased at 60 and 90 min of pneumoperitoneum and immediately after the end of pneumoperitoneum,Pplat was decreased at 60 and 90 min of pneumoperitoneum,the dynamic lung compliance was increased at 30,60 and 90 min of pneumoperitoneum and immediately after the end of pneumoperitoneum,and the time for achieving extubation standard,time for achieving the standard for discharge from PACU,feeding time,and duration of hospital stay were shortened in group R (P＜0.05 or 0.01).In group C,one patient did not present with indications for extubation and were transfered to intensive care unit for continuous ventilation support.Conclusion Intraoperative alveolar recruitment maneuver can effectively improve the intraoperative pulmonary function and promote the recovery of postoperative pulmonary function in the morbidly obese patients undergoing laparoscopic sleeve gastrectomy.

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 evaluate short-term fowllow-up results of castable ceramic-IPS Empress Ⅱ onlays in restoring severe tooth defects with low occlusogingival dimension from clinical aspects.Methods 41 units of the onlay were fabricated and applied in 37 patients,who were divided into experimental group and control group.The experimental group were restored with IPS EmpressⅡcastable ceramic onlay which was bonded by a dual-cure adhesive system.The control group were restored with mental onlay which was bonded by glass-ionomer cements.All these cases were followed at 6 and 12 months after cementation of the restorations.Metewands were established to evaluate its clinical effects.Results Onlay made from IPS Empress Ⅱ castable ceramic demonstrated natural and esthetical appearance.In addition,proximal contact,retention and marginal fit of the restorations were good.No gingivitis was found.Conclusion The reliability of onlay made from IPS Empress Ⅱ castable ceramic is greatly improved due to the strengthening effects of the lithium disilicate structures.In addition,the better esthetics compared to resin filling technique makes it a comparatively ideal all-ceramic system for onlays.

A solution with different Cu supply levels was cultured to investigate gama-aminobutyric acid (GABA) accumulation in Elsholtzia splendens, a native Chinese Cu-tolerant and accumulating plant species. Increasing Cu from 0.25 to 500 micromol/L significantly enhanced levels of GABA and histidine (His), but considerably decreased levels of aspartate (Asp) and glutamate (Glu) in the leaves. The leaf Asp level negatively correlated with leaf Cu level, while leaf GABA level positively correlated with leaf Cu level. The leaf Glu level negatively correlated with leaf GABA level in Elsholtzia splendens. The depletion of leaf Glu may be related to the enhanced synthesis of leaf GABA under Cu stress.
