Objective To explore the psychological intervention effect of ulinastatin combined with Xuebijing in the treatment of severe sepsis. Methods 76 patients with severe sepsis in our hospital from January 2016 to March 2017 were selected,and according to the different nursing intervention divided into observation group and control group,38 cases in each groups. control group with Ulinastatin and Xuebijing treatment, observation group with Ulinastatin and Xuebijing plus psychological intervention; before and after treatment in two groups of patients with clinical symptoms, psychological status (SAS and SDS score) to improve the situation, and the related data for comparative analysis. Results Ulinastatin and Xuebijing+psychological intervention (observation group) the clinical effect of treatment of severe sepsis patients than Ulinastatin and Xuebijing (control group) the clinical treatment effect of inflammatory factors in patients with improvement than the control group, SAS and SDS was better than that of control group, the difference was statistically significant (P<0.05). Conclusion severe sepsis patients choose the Ulinastatin+Xuebijing+psychological intervention of ulinastatin Xuebijing significantly, can effectively reduce the level of inflammatory factors in the patients, and fully improve the psychological status of patients, is worthy of clinical application.

Objective To analyze the effects of curcumin combined with cisplatin on the growth and lymphatic metastasis of cervical cancer xenografts in nude mice.Methods The human cervical carcinoma Caski cells xenotransplanted tumor models were established.Inoculated mice were randomly divided into 4 groups according to random number table:control (normal saline 10 ml/kg),Cur (curcumin 100 mg/kg),Cis (cisplatin 3 mg/kg) and Cur + Cis group (100 mg/kg curcumin +3 mg/kg cisplatin).The tumor volume and anti-tumor rate were calculated.The mRNA levels of macrophage migration inhibitory factor (MIF) and vascular endothelial growth factor-C (VEGF-C) were analyzed by real-time fluorescent quantitative polymerase chain reaction (PCR).Results The inhibitory rates of Cur group,Cis group and Cur + Cis group were 40.8％,53.3％ and 60.0％.After 15 days treatment,the tumor volumes of the control group,Cur group,Cis group and Cur + Cis group were (123.44 ± 35.62),(71.72 ± 28.36),(65.47 ± 18.32),(53.44 ± 10.79) mm3.The growth rates of tumor volume in Cur group,Cis group and Cur + Cis group were slower,Cur + Cis group could more effectively inhibit tumor volume growth.The difference among the four groups had statistically significance (F =16.890,P =0.000).Real-time fluorescent quantitative PCR detection showed that compared with the control group (1.000),the MIF mRNA expressions in Cur group,Cis group and Cur + Cis group were 0.322 ±0.094,0.154 ± 0.006 and 0.136 ± 0.007,VEGF-C mRNA expressions in the three groups were 0.312 ± 0.068,0.263 ± 0.072 and 0.221 ± 0.041.The differences among groups had statistically significance (F =220.279,P =0.000;F =143.250,P =0.000).MIF mRNA was positively related with VEGF-C mRNA (r =0.815,P =0.001).Conclusion Curcumin combined with cisplatin can inhibit the growth of Carski cell xenografts in nude mice.Through the down-regulating expression of MIF mRNA and VEGF-C mRNA,cisplatin and curcumin can inhibit the lymphatic metastasis of cervical cancer,and it may be one of the important mechanisms of its anti-tumor effects.

With the development of digital hospital construction,the concept of digital hospital has been accepted by lots of hospitals.All sorts of medical information purely facing to medical affairs and its integrated research have become more and more important.Digital management of medical service in hospital has been one of the important field in hospital management,so it has brought a new research orientation on application in the communication standard of medical service.

ObjectiveTo analyze the clinical features and prognostic factors of occult breast cancer. MethodsThe clinical features and prognostic factors of 62 occult breast cancer patients,who were treated in Tianjin Cancer Hospital from October 1997 to October 2011,were retrospectively analyzed.ResultsThe 3-year,5-year and 10-year overall survival rates of 62 cases were 87.4％,76.4％,73.2％ respectively,a median of 53 months.The 3-,5-,and 10-year overall survival rates of the patients with ＞4 positive lymph nodes are lower than that of patients with ≤4 nodes (77.8％,64.8％,38.9％ vs.90.7％,86.7％,86.7％,P =0.015 ) ;The 3-year and 5-year overall survival rates of patients with primary cancer found in removed breast tissue are lower than that in those primary tumor was not found (60.0％,40.0％,40.0％ vs.92.0％,83.6％,79.2％,P =0.023).The 3-year,5-year and 10-year overall survival rates in patients with recurrence and metastasis are lower than that of patients without (63.5％,28.6％,19.0％ vs.97.1％,97.1 ％,97.1％,P =0.000). ConclusionsThe prognosis of occult breast cancer is related with the number of positive lymph node,pathology,recurrence and metastasis.

Objective To discuss the feasibility and value of routine clinical preoperative examination predicting benign and malignant thyroid nodules. Methods The clinical data of 1630 patients undergoing thyroidectomy for nodular thyroid disease were analyzed retrospectively.The relationship between pathological diagnosis and physical examination,ultrasonographic parameters,the results of laboratory test and nuclear medicine test were examined to build a risk prediction model.The sensitivity,specificity and accuracy of the formula were tested. Results In 387 cystic nodules 0.78％ were malignant; In 1243 solid nodules 17.2％ were malignant.Among the 1243 cases,characters significantly related to malignancy were:age younger than 40 years,solitary lobe involvement,hypoechoic nodule,irregular margins,solid nodule,microcalcification,macrocalcification,max diameter ≤ 2 cm. The prediction formula was: malignancy indicator =0.80 × age + 0.59 × solitary lobe + 0.72 × hypoechoic + 0.82 × irregular margin + 1.32 × solid nodule + 1.90 × microcalcification + 0.70 × macrocalcification + 0.71 × max diameter.The threshold limit value was 2.8,and the sensitivity,specificity and accuracy of which were 74.4％,80.4％ and 75.2％,respectively. Conclusions Benign and malignant thyroid nodules could be differentiated roughly with the combination of patients' general information and the results of routine examination before operation.

The conventional invasive tissue blood oxygen content measurement is poor in continuity.The weakness of the signal,strong interference and random transmission of the photon in tissues make the measurement difficult.Recently,near infrared spectrum technology has been applied to tissue blood oxygen content measurement.This paper presents a hardware design method for tissue blood oxygen content measurement by near infrared spectrum technology.

A kind of saliva glucose detector based on electrochemistry is designed to measure the saliva glucose of diabetes mellitus, so as to achieve non-invasive measurement for diabetes mellitus state. A Prussian blue modified glassy carbon electrode was designed as the working electrode of the three-electrode system to improve the electrode sensitivity to H2O2's electrochemical reaction in a lower voltage. A three-electrode system was employed for measuring the current generated by the oxidation-reduction reaction of glucose catalyzed by glucose oxidase. Technique of shield-driving was used to avoid the attenuation of the voltage when it was processed, so as to ensure the precision measurement. A single chip microcomputer, C8051F020, was used to control the system and provide scanning voltage for the electrode, make A/D transition and process the result. Then the outputs were displayed on liquid crystal display. This detector's operating voltage was 0.496 V. The sensitivity was 0.1 mmol/L. There was a constant of proportionality between the measuring results of this detector and the precise analysator, Lanbiao LK98B. Results of the study show that this detector has low operating voltage, high sensitivity and good function of whole system, and can meet the request of measure.
