Purpose:It has been shown that the heart is a chaotic oscillator. So it is appropriiate to use the Lyapunov exponent, an important parameter to identify the nature of non-linear dynamical systems, for identifying the state of human heart. Methods:Preliminary results are obtained in this paper using Wolf's algorithm for 8 normal and 107 abnormal ECG recordings. Results:Significant differences are found between the Lyapunov exponents of normal ECG and ECG with obvious coronary stenosis (OCS), but there is no significant difference between the Lyapunov exponents of normal ECG and ECG with mild coronary stenosis (MCS);Significant differences are also found between the Lyapunov exponents of R-R interval series of normal ECG、ECG with MCS and ECG with OCS. Conclusions:It is apparent that the R-R interval series can give us more messages about human heart, and the Lyapunov exponents of ECG and R-R interval series are the appropriate parameters for the identification of the physiological states of human heart. It is possible to use Lyapunov exponent for early diagnosis of Coronary Heart Disease.

Radiotherapy can improve the local control rate of the tumors by destructing the tumor cells within the radiation field, can reduce the distant spread by activating the body 's anti-tumor immune response through various mechanisms, and also can exert systemic anti-tumor effect synergistically assisted by immunotherapy. As a new combination therapy, a large number of studies have found that local radiotherapy combined with different immunotherapy can benefit the survival of cancer patients. The optimal efficacy is closely related to the appropriate radiotherapy dose, segmentation model and combined timing. This paper discusses the effects of radiotherapy on the immune system, the related basic and clinical researches of radiotherapy and immunotherapy, and the better way to make the combination effectively.

24 patients with chronic hepatitis B were treated with interleukin-2 activated human peripheral blood lymphocytes (IAPBL). 23 patients served as control. The results showed that HBeAg disappeared in 54.2% of IAPBL group, in comparison with 17.4% of the controls (P

OBJECTIVETo prepare the nasal thermosensible gels of Chinese medicine Xingbi and study the release mechanism.

METHODThe gels were prepared by using P407 as the gel matrix and P188 and PEG 6000 were used to adjust the gelatination temperature. The formulations were screened by the method of orthogonal test. Mathematic models were used to imitate the drug release.

RESULT20% poloxmar 407, 2% poloxmar 188 and 2% PEG 6000 were suitable to Chinese medicine Xingbi thermosensitive gel in situ. Nasal thermosensible gels of Chinese medicine Xingbi was gelated at the temperature between 32-34 degrees C and the dissolution curves in vitro showed that the drug release could be best described by the Higuchi equation.

CONCLUSIONThe formulation of the nasal thermosensible gels of Chinese medicine Xingbi is reasonable and it is worth doing further research.

Objective To observe the clinical effect of ultrasound-guided technology in the operation of upper limb in patients with nerve block. Methods Two huandred patients had be performed upper limb operation in our hospital form Jan2012 to Dec 2013 were randomly divided into two groups, 100 cases of each group, group A who was guided by tra-ditional anatomical method;group B who was guided by ultrasound-guided positioning technolog, 1% Lignocaine +0.375%Ropivacaine+10 mg Dexamethasone were injected in two groups. Comparison of the effect of two groups nerve block: the onset time of anesthesia, success rate, the amount, complications. Results Anesthesia operation completion time, group B was shorter than group A (TA=7.7±1.9min, TB=4.6±1.4min);Nerve block work time, group B was longer than groupA(TA=19.4±3.4min, TB=10.7±2.3min);group B anesthesia effect was good, with excellence rate reached 97%and fine rate was 100.00%;group A anesthesia effect was general, excellence rate reached 47.00%,fine rate was 91.00%;group B adverse reactions incidence was 2.00%, group A was up to 9.00%;compared the above group A and B related datas of difference was statistically significant (P<0.05).The duration of anesthesia (TA=417.5±98.7min, TB=406.3±79.1min), the more similar between two groups had no statistical significance (P>0.05). Conclusion Ultrasound-guided technology was applied to the upper limb brachial plexus block, which could enhance the effect of nesthesia, re-duce the dosage of anesthetic drug ,complications and adverse reaction.

Objective To study on 24 hours hernia grassroots level in the district hospital management model practices. Methods The subjects were 283 cases of inguinal hernia patients selected from January 2008 to December 2010 in our hospital as the traditional model of the group , the treatment in the traditional management model , our hospital im-proved the management mode after January 2011 , 326 cases of inguinal hernia patients selected from January 2011 to December 2013 in our hospital as a new model group , that under the new model in 24 hours hernia treatment mode. Results Under the new model,patients waiting for surgery, hospitalization time and the days of antibiotic use were sig-nificantly shorten than the traditional model , the cost of hospitalization was significantly reduced , the difference was statistically significant (P<0.05). Under the new model, patient satisfaction was significantly higher than the traditional model, and the complication rate was significantly lower than the traditional model, the difference was statistically sig-nificant (P<0.05). Conclusion 24 h hernia is safe, effective, and economic characteristics, enabling a more rational use of health care resources and deployment , significantly reducing health care costs , can promote the application in district hospitals.

Bronchiectasis has the characteristics of long course,gradual aggravation,easy recurrence and difficult to treat.The characteristics are similar to those arouse by incubative pathogenic factors.Based on the theory of incubative pathogenic factors,this disease is often related to the incubative pathogenic factors in the body's areas with deficient healthy qi,which occur at regular times.The etiology can be external,congenital,or internal.Treatment should focus on different characteristics of incubative pathogenic factors.Attention should be paid to clearing and dispersing in external pathogenic factors,while attention should be paid to supporting and promoting healthy qi in congenital pathogenic factors,and do not forget to remove internal pathogenic factors.

OBJECTIVETo screen molecular markers in early breast cancer and establish gene subtyping-based diagnostic criteria for predicting the prognosis of early breast cancers.

METHODSTumor tissue specimens were obtained from 8 patients with early breast cancer for analysis of the differentially expressed genes using Agilent custom 8×15 000 chips in combination with the prognostic data of the patients. Another 42 tumor tissue specimens were used to validate the differential genes by real-time fluorescent quantitative PCR.

RESULTSGene microarray analysis identified 132 differentially expressed genes between the patients with favorable and poor prognosis, and 44 of these genes were significantly up-regulated (by over two folds) and 88 down-regulated in patients with poor prognoses.

CONCLUSIONThe gene expression profiles differ in early breast cancer tissues of the same pathological type but with different clinical stages and prognoses, and CD44, MKI67, NTRK2, Nek2, C16orf60, TOP2A, ANCCA, and RRM2 genes can be used as the prognostic markers for early breast cancer.

As the main weapon of cellular immunity,CD4+ T cells play a vital role in controlling and eliminating infections,and are an important barrier for the body to resist infections.Respiratory tract infectious diseases caused by influenza virus infection have extremely high infectivity,morbidity and mortality.The infection mechanism is relatively complicated and has not been fully ex-plained.The exuberant immune response induced by the body after influenza virus infection is described as a"cytokine storm"which is related to pro-inflammatory cytokines and tissue damage,which may eventually lead to acute lung injury.Therefore,this article sum-marizes the current research progress,focusing on the mechanism of CD4+T cells in the cytokine storm induced by influenza virus in-fection and the impact of acute lung injury,providing relevant ideas and theoretical guidance for follow-up research,with a view to the disease caused by influenza virus bring new and effective methods of diagnosis and treatment.
