Colorectal stem cells have many bio-markers, including Lgr5 which expression is associated with THE stage of disease , also regulating the cell cycle , anothers is +4 stem cell , which is associated with tumor heteroge-neity, also expressed Bmi1, arresting cell cycle.Besides there is Msi1.Many studies show that those markers are highly expressed in colorectal cancer , which activate Notch and Wnt signaling pathway , and can promote the pro-gress of tumor .

Musashi1 (Msi1) is an evolutionary conservative RNA-binding protein (RBP),and it is a stem marker in a variety of organizations,including intestinal,neural system.Msi1 maintains the balance between self-renewal and differentiation.Recently,many researchers report that Msi1 is overexpressed in many types of tumors,especially in colorectal neoplasms,participating in the regulation of cell cycle,proliferation,apoptosis and so on.Msi1 becomes a key regulator of many cancers,which is expected to turn into a new target for cancer therapy.

Objective Diabetes is a common chronic disease in the elderly and needs long-term treatment. This study aims to determine the effect of extended nursing service in rehabilitation of army retired officers with diabetes. Methods We selected 78 ca-ses of military retired officers with diabetes from September 2010 to September 2012 in Nanjing General Hospital of Nanjing Military Region. According to the different intervention methods, patients were divided into experimental group and control group( n=39 cases) . The control group used conventional nursing service, and the experimental group added extended nursing service on the basis of the control group . After one year follow-up, the fasting blood glucose level, glycosylated hemoglobin ( HbAlc) , self-rating depression scale (SDS) evaluation and self-rating anxiety scale (SAS) and the changes of patients′ satisfaction of the two groups were observed. Results The fasting blood glucose levels and HbAlc of experimental group were significantly better than control group, with statisticalsignificance (P<0.05);The SAS scores (34.9±5.9)and SDS scores (36.9±4.5) of experimental group were significantly lower than the control group(52.3±4.2 and 55.9±3.9), with statistical significance ( t=5.489, t=5.226, P<0.05);The satisfaction degree of the exper-imental group was significantly higher than the control group (99.8%vs 79.9%, χ2=4.898, P<0.05). Conclusion the extension ofnursing service in health rehabilitation in the retired veteran cadres in the army with diabetes can effectively improve the patient′s fast-ing blood glucose levels, reduce depression, as well as improving the nursing service satisfaction.

Objective To explore the effect of the unilateral lumbar anesthesia by hypobaric bupivacaine and general anesthe‐sia in elderly hip replacement and their influence on the stress response .Methods Forty elderly patients undergoing hip replace‐ment in our hospital from December 2013 to November 2014 were selected and randomly divided into the unilateral lumbar anesthe‐sia group and general anesthesia group according to the random number table ,20 cases in each group .Venous blood was collected to determine the levels of blood sugar ,serum catecholamine(CA) and cortisol(CORT ) at 10 min before anesthesia(T0 ) ,end of surgery (T1 ) and at postoperative 24 h(T2 ) .MAP ,HR ,SpO2 ,intraoperative adverse reactions and postoperative related complications were recorded at each time point ,and the comparative analysis was performed .Results All patients successfully completed surgery and the anesthetic effect was satisfied .The occurrence rates of intraoperative hypotension ,hypertension and bradycardia in the unilateral lumbar anesthesia group were lower than those in the general anesthesia group ,the differences had statistical significances (P>0 .05) .HR and MAP at T1 in the two groups were reduced ,but the differences between the two groups were no statistical signifi‐cance(P>0 .05);the levels of GLU ,CORT and CA were increased ,moreover the differences between the two groups were statisti‐cally significant(P<0 .05) .SpO2 at T2 in the general anesthesia group was obviously lower than that in the unilateral lumbar anes‐thesia group ,while CORT was higher than that in the unilateral lumbar anesthesia group ,the differences were statistically signifi‐cant(P<0 .05) .The occurrence rates of postoperative nausea and vomiting ,sore throat ,dizziness ,drowsiness and pulmonary infec‐tion in the unilateral lumbar anesthesia group were lower than those in the general anesthesia group ,the differences were statistical‐ly significant(P<0 .05) .Conclusion The unilateral lumbar anesthesia by using hypobaric bupivacaine and general anesthesia all could offer better anesthetic effect .The unilateral lumbar anesthesia by using hypobaric bupivacaine can effectively regulate the stress response in elderly patients with hip replacement .

Objective To evaluate the role of AMP-activated protein kinase (AMPK)-dependent autophagic signaling pathway in ketamine-induced reduction of diabetic neuropathic pain (DNP) in rats.Methods Sixty male Wistar rats,aged 3 months,weighing 200-250 g,were equally randomized into 5 groups using a random number table:control group (C group),normal saline group (NS group),ketamine group (K group),ketamine + Compound C group (KC group),and ketamine + 3-methyladenine (3-MA) group (KM group).DNP model was established by intraperitoneal injection of streptozocin (STZ)65 mg/kg in anesthetized rats.Four weeks later,the equal volume of normal saline,ketamine 10 mg/kg,ketamine 10 mg/kg + Compound C1 mg/kg,and ketamine + 3-MA 2 μl were injected intraperitoneally once a day for 7 consecutive days in NS,K,KC and KM groups,respectively.The mechanical paw withdrawal threshold (MWT) was measured on 8th day.The rats were then sacrificed,and the lunbar segment (L1-5) of the spinal cord was removed for determination of the expression of AMPKαt,Beclin-1,microtubule-associated protein 1 light chain (LC) 3B (by Western blot) and dendritic spine density in the dorsal root ganglia.Results Compared with group C,the MWT,expression of AMPKα,Beclin-1,and LC3B,and dendritic spine density were significantly decreased in group NS (P＜0.05).Compared with group NS,the MWT,expression of AMPKαt,Beclin-1,and LC3B,and dendritic spine density were significantly increased in group K (P＜0.05).Compared with group K,the MWT,expression of AMPKα,Beclin-1,and LC3B,and dendritic spine density were significantly decreased in KC and KM groups (P＜0.05).Conclusion Activation of AMPK-dependent autophagic pathway is involved in ketamine-induced reduction of DNP in rats.

Objective To explore the effects of two methods for deep endotracheal suction.Methods Forty patients who had ineffective airway clearance or lung infections or refused suction were randomly divided into observation group (n=21) and control group (n=19).Temporay airway was established by using oropharyngeal airway.Then,the control group received subglottic suction after pading the shoulder with ordinary pillow (≤10cm),while the observation group received subglottic suction after pading the shoulder with homemade pillow (=15cm).The two groups were compared in terms of sputum suction effect and mucosal injury.Results There was no incidence of mucosal injury in the observation group but three in the control group.The times of suctioning in the observation group were fewer than those of the control group and the volume for suctioning was larger as well (allP<0.05).Conclusion Deep endotracheal suction through oropharyngeal airway,shoulder elevation for 15cm,temporary indwelling of suction tubes can achieve better suction effect without corresponding complications.

Background: Radiation pneumonitis is one of the most common complications during radiotherapy of thoracic tumors. It impacts the quality of life of the patients and has life-threatening danger. However, there is a lack of drugs for prevention and treatment of this disease. Objective: To evaluate the efficacy of Liangxue Jiedu Huoxue Decoction, a compound traditional Chinese herbal medicine, in prevention of radiation pneumonitis. Design, setting, participants and interventions: A prospective randomized clinical study was conducted. A total of 100 patients diagnosed with lung cancer from Department of Radiotherapy, Chinese PLA General Hospital, who were planning to receive radiotherapy, were randomly assigned into treatment group and control group, with 50 patients in each group. In the treatment group 3 cases were lost to follow-up and one case was excluded, while in the control group 6 cases were lost to follow-up and 2 cases were excluded. Patients in the treatment group were treated with Liangxue Jiedu Huoxue Decoction in addition to radiotherapy, while patients in the control group were treated with radiotherapy alone. Main outcome measures: The incidence rates of radiation pneumonitis in the two groups were calculated. Acute radiation injury scoring criteria by Radiation Therapy Oncology Group (RTOG), clinical-radiographic-physiologic (CRP) score system, and Karnofsky Performance Status Scale (KPS) were used to evaluate the status of the patients. Results: The incidence rate of radiation pneumonitis was lower in the treatment group than in the control group (13.04% versus 33.33%, P<0.05). According to the RTOG scale, the extent of lung injury was improved in the treatment group as compared with that in the control group (P<0.05). The CRP score in the treatment group was significantly lower than that in the control group (P<0.05). The KPS score in the treatment group was significantly higher than that in the control group (P<0.05). Conclusion: Liangxue Jiedu Huoxue Decoction can decrease the incidence rate of radiation pneumonitis, reduce the extent of the lung injury, alleviate the symptoms of radiation pneumonitis, and improve life quality of the patients.
