Objective To investigate the effect of bundle strategy of diagnosis and treatment on preventing hospital acquired pneumonia in intensive cancer patients.Methods Two hundred and sixty-five patients as control group were treated by regular preventive measures,and 292 cases as intervention group were treated by bundle strategy including the control application of antibiotics,hand hygiene,oral care,isolation of multi-drug resistant,elevation of bedside,management of respiratory tract and appropriate sedation and analgesia et al.Compare the hospital acquired pneumonia incidence,attribution mortality,duration of mechanical ventilation,stay-time in ICU,hospital acquired pneumonia antibiotics defined daily doses system and positive rate of multi-drug resistant infection between two groups.Results With the bundle treatment,the decreases of the hospital acquired pneumonia Incidence,duration of mechanical ventilation,stay-time in ICU and hospital acquired pneumonia Antibiotics daily doses system were significant(P＜ 0.01),and the positive rate of hospital acquired pneumonia attribution mortality and MDR infection were no statistical significance (P ＞ 0.05).Conclusion The bundle strategy of diagnosis and treatment could reduce the hospital acquired pneumonia incidence and the length-time in hospital.

Objective: To study the effect of fish-oil fatty emulsion on immunity of post-operation patients with malignancy tumors.Methods: Forty-three post-operation patients with malignancy tumors were randomly divided into control group and study group and both groups were provided with parenteral nutrition treatment [104.6 kJ(25 kcal/kg)].Fish-oil fatty emulsion was given to the study group.The level of serum albumin,immunity function,jaundice index,aminotransferase,blood lipid and morbidity rate of infectious complications of the two groups were compared.Results: After five days of post-operation treatment,in the study group,the immunity function was significantly improved and morbidity rate of infectious complications declined.The levels of serum albumin,the blood lipid,jaundice index,and aminotransferase had no significant difference between the two groups.Conclution:Fish-oil fatty emulsion is beneficial to the immunity function and can emilsion decrease infectious complications of post-operation patients with malignancy tumors.

Objective To explore the in vivo killing effects of nanosecond pulsed electric fields on mouse breast cancer in tumor bearing BALB/c mice. Methods Twenty four BALB/c mice models with subcutaneous EMT-6 breast cancer were prepared and divided into experimental group and control group (n=12). In experimental group, the mice were treated by the pulsed electric fields with peak voltage of 700 V/cm, rise times of 57 ns, durations of 70μs and duty ratio of 50%on the tumor tissue with two parallel electrodes under anaesthesia. One hundred pulses were given and the energy was just 9.75 J with effective action period of 7 ms. Tumor volume, animal weight and histopathologic changes after 1, 3, 5 and 7 d were observed after irreversible electroporation. Results The tumor volume in experimental group increased more slowly than that in control group, especially at the 1-3 d after treatment with a standstill. Histopathological examination results showed that the tumor tissue had obvious coagulation necrosis and tissue edema after electrical stimulation treatment, and mass vacuole like structure appeared in tumor tissue from the third day after treatment and vascular injury occurred at the early stage. Conclusions In the given field conditions, steep pulsed electric field has inhibitory effect on tumor growth. In order to achieve more ideal tumor therapy effect, further studies on steep pulse dose are needed.

Objective To study the safety and feasibility of tubeless percutaneous nephrostolithotomy by hemostasis gel closure of mini-percutaneous renal-channel.Methods Eighty patients after conventional percutaneous nephrostolithotomy are selected and divided into two groups according to the principle of randomization.Control group adopts conventional percutaneous nephrostolithotomy calculi lithotripsy with renal pelvis drainage tube placement whereas the experimental group adopts tubeless percutaneous nephrostolithotomy by hemostasis gel closure of mini-percutaneous renal channel.Both experimental group and control group will be scientifically and statistically analyzed via the incidence and the dose of using sedative for alleviating pain after operation,hospital stay,level of hemoglobin,and the occurrence of complications such as continuate hemorrhage,infection,urinary extravasation,etc.Results The operation of both groups are successful in phrase Ⅰ.The incidence and the dose of using sedative in control group are obviously higher than that in experimental group(45％ vs 20％).However,the incidence of postoperative complications like infection and hemorrhage and hospital stay between two groups are undifferentiated in statistics(P ＞ 0.05).Neither the experimental group nor the control group has perinephric hematoma,and seven cases of control group have urinary leakage after remove of fistula.Conclusion Tubeless percutaneous nephrostolithotomy by hemostasis gel closure of mini-percutaneous renal-channel is safe and feasible and it can reduce the incidence of postoperative pain and avoid urinary leakage.

Objective To investigate the effects of intravenous immunoglobulin(IVIG)on thrombocytopenia associated with sepsis.Methods Fifty-two septic thrombocytopenia patients were randomly derided into IVIG group and control group,with 26 patients in each group.IVIG with dose of 400 mg/(kg?d)for 5 days was intravenously administered together with conventional treatment in IVIG group.Before and after IVIG treatment,platelet(PLT)counts,TNF-?,IL-6 and APACHEⅢscore were determined.Results In treatment group platelet counts were increased after IVIG treatment at 3 and 7 days in the IVIG group(P＜0.05);The bleeding rate and APACHEⅡwere significantly lower than control group,TNF-?level was lower at 3 days after treatment than cortrol group,and IL-6 level was lower at 1,3,and 7 days ( P＜0.05).Conclusion The use of IVIG to treat septic thrombocytopenia leads to a rapid and great increase in platelet count and significantly reduce the incidence of bleeding episode and TNFa,IL-6 level and APACHEⅢscore.

The incidence of cancer has remained high in recent years, and anti-tumor treatment methods are emerging. Cancer treatment has undergone significant changes, and the survival rate of patients with cancer has significantly improved. Various types of new anti-tumor treatments may not only treat and control tumor growth but also place patients in critical situations that require treatment by intensive care medical personnel. Patients with cancer are in critical condition mainly due to three reasons: severe cases caused by cancer diseases themselves, complications during the perioperative period, and accompanying diseases and hospital acquired diseases. In the new situation, we should consider patient characteristics, such as abnormal metabolism, abnormal coagulation system, and abnormal immune mechanism, to save them from serious illness. We need to comprehensively evaluate patients with cancer, emphasize the role of the Intensive Care Unit (ICU) treatment platform, and promote the treatment concept of planned transfer to ICU, to improve the success rate and efficiency of treatment. After transferring the patient out of the ICU, the planned follow-up anti-tumor treatment can still be continued as the endpoint of ICU treatment for critically ill patients with cancer. In the future, efforts will be devoted to establishing a discipline and talent echelon with distinctive characteristics of oncology critical care medicine and treating "the critical illness of cancer and the cancer of critical illness".

Objective To assess the value of 64-slice computer tomography used in the preoperative evaluation of rectal cancer to predict the operative procedures. Methods There were 51 pathologically proven rectal cancer patients recruited, undergoing multi-slice computer tomagraphy (MSCT) assessment preoperatively. Preoperative MSCT stage and predictive operative procedures were recorded to compare with postoperative pathological stage and practical operative procedures. Kappa Coefficient for Diagnosis Coherence and Spearman correlation analysis were performed. Results The overall accuracy of CT-TNM stages were 74.5% which led to high coherence to pathological TNM stage ( Kappa value = 0.658,P=0.000). The univariate analysis showed that distance from tumor to dentate line (F = 3.386, P =0.042 ) and tumor thickness (F = 4.542, P = 0.016) was a statistically risk factor for operative procedures. Moreover, the significant correlation between tumor thickness (cc =0.319, P =0.023 ), as well as CT-M stage (cc = 0.369, P = 0.008) and CT-TNM stage ( cc = 0.365, P = 0. 008), and operative procedures was observed, by means of conducting Spearman correlation. The possibility of developing palliative stoma was 75%, when sufficing both CT-MI stage and tumor thickness ≥20 mm; The possibility of performing sphincter sparing radical operation reached 86% when both CT-T stage < 4 and distance from tumor to dentate line were referred by MSCT. Conclusion The objective parameters influencing development of operative procedures, involving tumor thickness, CT-M stage and CT-T stage, can be rendered by MSCT preoperative assessment, which served as valuable reference for clinical decision of operative procedures in retal cancer.

Objective To investigate the related risk factors of the previous cemented vertebral body re-wedge after percutaneous kyphoplasty (PKP).Methods In this retrospective case-control study,clinical data of 617 patients treated by PKP from December 2008 to November 2014 were analyzed.According to whether the cemented vertebra wedged again,the patients were divided into cemented vertebral re-wedge group (n =12) and non-cemented vertebral re-wedge group (n =605).The data of age,preoperative bone density,preoperative vertebral osteonecrosis,intraoperative bone cement injection amount,postoperative bone cement leakage,postoperative bone cement filling,postoperative recovery rate of vertebral wedge angle,and presence or absence of adjacent old vertebral wedging were recorded in two groups.All patients were followed up for one year,and the data were summarized and statistically analyzed.Results Single factor analysis showed the factors of whether there were adjacent old vertebral wedge,preoperative vertebral osteonecrosis,cystic bone cement filling,different wedge angle recovery rate,and emergence of previous cemented vertebral body re-wedge after PKP were statistically significant between two groups (P ＜ 0.05).There was no obvious statistical difference in age,preoperative bone density,intraoperative bone cement injection amount,and intervertebral bone cement leakage between two groups (P ＞ 0.05).Multivariate Logistic stepwise regression analysis showed cystic bone cement filling,preoperative vertebral osteonecrosis,adjacent old vertebral wedging,and higher recovery rate of vertebral wedge angle were prone to appear previous cemented vertebral body rewedge (P ＜ 0.05).Conclusions Relatively higher recovery rate of vertebral wedge angle,previous adjacent old vertebral wedge,vertebral osteonecrosis,and cystic bone cement filling are risk factors closely related to cemented vertebral re-wedge after PKP,which gives a good reference to assess surgical risk,avoid risk factors and choose right surgical techniques.

Objective To explore the effect and mechanism of relaxin on the production of extracellular matrix (ECM) excreted by high glucose stimulated human renal mesangial cells.Methods Cultured human mesangial cells (HMCs) were divided into three groups:(1) normal glucose group (NG,5.5 mmol/L D-glucose),(2) high glucose group (HG,30 mmol/L D-glucose),and (3) high glucose + relaxin group.Cell count kit (CCK8) was used to examine the cell proliferation.The levels of fibronectin and collagen type Ⅳ in the culture supernatants were examined with a solid-phase enzyme-linked immunoadsorbent assay (ELISA);Western blot method was used to detect the expression of α-smooth muscle actin (α-SMA) protein.The transforming growth factor-β1 (TGF-β1) mRNA expression was detected with quantitative polymerase chain reaction (qPCR) method.Results No proliferation and inhibition effects were observed in both normal and high glucose group.Compared to the normal glucose group,the levels of fibronectin,and collagen type Ⅳ increased significantly (57.28 ± 0.59 vs 41.85 ± 0.03,56.52 ± 0.88 vs 33.80 ± 0.24,P ＜ 0.01)after cultured 48 h in high concentration of glucose.Compared to the high glucose group,a significantly decreases of fibronectin and collagen type Ⅳ (47.08 ± 0.03 vs 57.28 ± 0.59,36.16 ± 0.52 vs 56.52 ±0.88,P ＜0.01) were observed in the relaxin treated group.The expressions of α-smooth muscle actin and TGF-β1 were decreased (P ＜0.01).Conclusions Relaxin can suppress the overproduction of ECM excreted by HMC cultured in high ambient glucose,and its mechanism is partly due to the inhibition of TGF-β1.
