Abstract: Superior mesenteric veinous thrombosis (SMVT) is a rare complication that often occurs in conjunction with intra-abdominal diseases such as diverticulitis, appendicitis, inflammatory bowel disease, etc. Its clinical symptoms are non-specific and include fevers, abdominal pain; it has no specific symptoms, and the diagnosis depends on clinical laboratory tests and imaging studies. The occurrence of superior mesenteric veinous thrombophlebitis is related to septic phlebitis caused by the sloughing of the embolus containing bacteria into the portal vein with blood flow. Due to the nonspecific clinical features of this disease, diagnosing it based on clinical characteristics and microbiological aspects is a challenge. A case of superior mesenteric veinous septic thrombophlebitis caused by Bacteroides fragilis infection is reported and to provide a reference for the diagnosis and treatment of such diseases. The patient was a 34-year-old man who was admitted the hospital with intermittent abdominal pain and fever. Computed tomography (CT) showed partial thrombosis of the superior mesenteric vein, colonoscopy revealed diverticulitis in the ileoceca, and the blood culture grew Bacteroides fragilis. The patient was treated with anti-infection (ceftazidime 2.0 g q12h intravenous infusion for 11 days; metronidazole 0.5 g, q8h intravenous infusion for 3 days) and anticoagulation (rivaroxaban 20 mg qd orally for 8 days. On the 11th day of hospitalization, the patient's condition improved, and he was discharged. In this case, for patients with fever and abdominal pain, superior mesenteric venous thrombophlebitis should be included in the differential diagnosis. Through auxiliary examination, blood sample culture and other technologies, clear diagnosis should be made in time to improve patient outcomes.

Objective To explore the application effect of de-escalation thinking shift mode in emergency condition of morning shift meeting. Methods Guided by the de-escalation thinking, critical ill patients transfer tables were established in the emergency department, patients admitted into the emergency resuscitation room were selected from January 2015 to December 2015, and divided into the observation group (329 cases) and the control group ( 310 cases) . Patients in the control group applied the traditional oral shift meeting mode by the bed to check the patient; patients in the observation group applied the de-escalation thinking shift mode of morning shift meeting, followed by the specification of morning shift process and content; additionally, the cooperation of nursing staff, the transfer of nursing adverse events, nurses awareness of the patient′s condition, the patient satisfaction survey were counted before and after the implementation, respectively. Results Chinese version of Nursing Assessment Shift Report (NASR) was used to evaluate the cooperation status between the two sides of nursing staffs, and the mean scores of nursing staffs were 60.50±1.80 and 78.20±2.50 in the control group and the observation group, respectively, showing statistical significance (t=14.23, P<0.01);before application, corresponding statistical results regarding the shift meeting related nursing adverse events showed that there were 5 cases of infusion prolapse/leakage, 2 cases of pressure ulcer, 3 cases of pipe extrusion, and 2 cases of delayed drug delivery;after application, there were 2 cases of infusion prolapse/leakage, 0 case of pressure ulcer, 1 case of pipe extrusion, and 1 case of delayed drug delivery;comparison results showed significantly statistical difference (χ2=1.76-6.74, P<0.05). Before application, assessment results regarding the mean scores of nurses awareness of the patient's condition showed that mean scores of patients′ state of illness, test results, current treatment, potential risk, and nursing focus were 3.83 ± 0.62, 3.16 ± 0.64, 4.17 ± 0.36, 3.47 ± 1.26, and 3.64 ± 1.10, respectively;and after application, mean scores of patients′state of illness, test results, current treatment, potential risk, and nursing focus were 4.71 ± 0.27, 4.53±0.66, 4.89 ± 0.10, 4.50 ± 0.61, and 4.72 ± 0.43, respectively;the differences were statistically significant (t=-8.86--3.35, P<0.05). Furthermore, patient satisfaction with nursing staff in emergency department was improved from 91.6%(284/310) to 96.0%(316/329)(χ2 =25.74,P<0.05). Conclusions The application of de-escalation thinking shift mode in emergency condition of morning shift meeting may contribute to the specification of the transfer process, improvement of nursing work efficiency, and finally result in the promotion of patients′safety and teamwork.

Objective To analyse the clinical characteristics,therapeutic modalities and prognosis of pulmonary large cell neuroendocrine carcinoma(LCNEC). Methods The clinical data of 14 patients with pulmonary LCNEC confirmed by surgery were retrospectively reviewed. Results No case was correctely diagnosed before surgery.The immunohistochemical amalysis of the specimens revealed the characters of endocrine carcinoma.Twelve cases received adjuvant chemotherapy of platinum agents,but recurrence or metastasis was found in 8 of them several months after surgery.The median survival time was 19 months.The 1-year,2-year and 3-year survival rate were 85.7%(12/14),21.4%(3/14) and not more than 14.3%(2/14),respectively.The statistical analysis showed that the stage,lymph node metastasis and postoperative adjuvant chemotherapy may have impacts on the prognosis of pulmonary LCNEC. Conclusion Pulmonary LCNEC is a carcinoma with poor prognosis,high tendency of invasion and metastasis.The stage of disease,lymph node metastasis,and adjuvant chemotherapy may be related to the prognosis.

Objective To investigate the effects of emulsified isoflurane preconditioning on myocardial NF-κB activity during ischemia-reperfusion(I/R)in rats.Methods Forty-eight healthy male SD rats weighing 230-280 g were randomly divided into 4 groups with 12 animals in each group: sham operation group(group S),I/R group,lipid emulsion + I/R group(group L)and emulsified isoflurane + I/R group(group EI).In group I/R,EI and L,myocardial I/R was produced by occlusion of left coronary anterior descending artery(LAD)for 30 min followed by 120 min reperfusion.In group L,30% lipid emulsion 4 ml·kg-1 ·h-1 was infused intravenously for 30 min before myocardial I/R.In group EI,emulsified isoflurane 4 ml· kg- 1 · h- 1 was infused intravenously for 30 min followed by 15 min washout before myocardial I/R.In group S and I/R,normal saline was given instead.Blood samples were taken from femoral artery at the end of 120 min reperfusion for determination of serum cTnI and IL-6 concentrations and CK-MB activity by ELISA.The rats were then killed and the myocardial tissues were taken for determination of NF-κB activity by Western blot and observation of the ultrastructure by electron microscopy.Results The NF-κB activity,serum cTnI and IL-6 concentrations and CK-MB activity were significantly higher in group I/R,EI and L than in group S(P ＜ 0.05 or 0.01),while lower in group EI than in group I/R(P ＜ 0.05).Microscopic examination showed that emulsified isoflurane significantly attenuated the histopathological changes in group EI.Conclusion Emulsified isoflurane pretreatment can attenuate myocardial I/R injury through decreasing the NF-κB activity and inhibiting inflammatory response in rats.

OBJECTIVETo investigate the leukogenic function of Shuanghuang Shengbai (SHSB) granule and the related mechanisms.

METHODMouse leukopenic models were induced by radiation. Mice were divided into normal control group, model control group, positive control group-Li kejun tablet group and three different dose (high, middle, low-dose) groups of SHSB granule. The peripheral hemogram, thymus index (TI), spleen index (SI), bone marrow nucleated cell (BMNC) and colony forming unit-spleen (CFU-S) were evaluated. The proliferation of bone marrow cells was determined. The in vitro cultured colony forming unit granulocyte macrophage (CFU-GM) was estimated. The index of CD34+ cell in BMNC were determined by flow cytometry. The ultra-micro structure of bone marrow were observed by electromicroscope.

RESULT(1)SHSB rranule could increase the WBC of model mice; (2)SHSB granule could increase BMNC and promote the proliferation of bone marrow cell; (3)SHSB granule could increase CFU-S, CFU-GM and CD34+ cell index in BMNC of model mice significantly; (4)SHSB Granule could also protect the bone marrow hemotopoietic microenvironment from the harm of radiation; (5)SHSB granule could increase the SI of model mice, indicating the enhancement of immunological function.

CONCLUSIONSHSB granule has apparent leukogenic function. The mechanism may be related to enhancing the proliferation of hematopoietic cells and protecting the bone marrow hemotopoietic microenvironment.
