Objective To investigate clinical therapeutic effect of zoledronic acid combined with chemotherapy to senile lung cancer with bone metastases.Methods Totally 80 cases of senile lung cancer patients with bone metastasis were randomly divided into control group and combined group,40 cases in each group.Limitation of activity to the situation,release of bone pain,adverse e-vents and side effects were observed.Serum Ca2+ concentration,alkaline phosphatase (AKP)levels and the levels of serum inflam-matory cytokines TNF-α,IL-1βwere detected.Results Limitation of activities and pain of patients with combined treatment was significantly ameliorated compared to control group (P <0.05).Serum Ca2+ ,AKP and TNF-α,IL-1β levels were significantly de-creased in patients with combined group in time-dependent manner,and which were significantly lower than control group.Bone ad-verse events and side effects in patients with combined treatment were significantly lower than in patients with control group.Con-clusion Zoledronic acid combined with chemotherapy can enhance the efficacy of chemotherapy,effectively relieve the limitation of activities and pain symptoms and reduce the incidence of bone adverse events and adverse reactions.The effect may be related to the decrease of serum calcium and the inflammatory cytokines.

The transcranial doppler ultrasonography (TCD) is a non-invasive detection methods of evaluating intracranial artery.Since the 1980s,TCD has been extensively used in various fields of clinical work.Because of its simple operation,good repeatability,and the continuous bedside observation of patients,TCD is especially suitable for severe patients.Increased intracranial pressure is one of the important reasons for the deadly disease in children,it can make the cerebral blood flow perfusion decreased,causing serious consequences,such as brain dysfunction,so intracranial pressure monitoring has important clinical significance.TCD as a noninvasive monitoring tool,can monitor the patients with increased intracranial pressure dynamically,according to the blood flow velocity,the related parameters and the wave of cerebral hemodynamics,so as to achieve the purpose of monitoring intracranial pressure change.This article focused on the TCD application progress in several common children's diseases of increased intracranial pressure.

Objective To investigate effect of intravitreal injection of FK506 on the survival of human retinal pigment epithelial (RPE) cells heteroplastically transplanted into the subretinal space of rabbits. Methods The immortalized human RPE cells were genetically labeled by retrovirus vector carrying a green fluorescent protein (GFP). A total of 50 ?l RPE cells suspension with 4?10 3 cells/?l which expressed GFP were injected into the subretinal space of both eyes of 18 white rabbits and 10 gray rabbits. The left eyes of all of the rabbits were injected of 5 ?l FK506 (5 ?g/?l) intravitreally once a week during the first 5 weeks, then once every other week until the 20 th week and the right eyes were as the control. The histological sections of heteroplastic RPE cells were observed by epifluorescent microscope. Results GFP-expressing cells could be seen after 1 week, 2, 3, 4, 6, 10, 11, 14, 18, 20, 23, 24, 25, 26, 33, and 54 weeks in white rabbits and after 4, 5, 6, 7, 14, 18, 20, and 26 weeks in gray rabbits. The configuration and integrality of the RPE-GFP cells in the left eyes which had been intravitreally injected of FK506 1-14 weeks after transplantation were better than those in the right eyes without injection. After 18 weeks, the condition of heteroplastic cells with few difference in both eyes in 7 white and 3 gray rabbits were found. After 1-6 weeks, focal and disseminated lymphocytes around the choroidal small vessles of right eyes in 6 white and 3 gray rabbits could be seen while the infiltration of the lymphocytes in the left eyes was much reduced. Conclusion Intravitreal injection of a small amount of FK506 at the first 3 months after transplantation may significantly improve the survival of heteroplastic RPE cells in the subretinal space of rabbits.

Traditional Chinese medicine (TCM) has its own system of diagnosis and treatment theory, and its methods for evaluating clinical efficacy are different from those of Western medicine. Applying evaluation techniques and methods that are used in Western medicine mechanically to TCM will not work. So building evaluation techniques, which adhere to regulations and characteristics of TCM, is necessary and imperative. As the quality of life and patient-reported outcome instruments were brought into practice and developed, clinical evaluation ideas and methods for TCM are provided with an opportunity for development. This article puts forward the concept of subjective complex outcomes (SCOs), which constitutes subjective feelings gained from the patient, doctor and caregiver, different from laboratory parameters. SCOs provide a multidimensional and complex health-related quality of life (HRQL) assessment and focus on the source of assessment information of diseases. This article also introduces a case study building SCO methods of TCM treatment for chronic obstructive pulmonary diseases, in order to promote discussion and provide a platform for future research.

Objective To generalize a valuable classification of mandibular condyle fractures and explore proper measures for such kind of fractures so as to provide reference for clinical treatment. Methods The data of 304 cases with 358 mandibular condyle fractures were analyzed retrospectively. After one year of the initial treatment, X-ray inspection was employed to get the information including mouth opening, pattern of mouth opening, occlusion, facial symmetry and healing condition of mandibular condyles. Results According to classification of position,displacement and age (PDA), 180 mandibular condyle fractures belonged to type Ⅰ, 96 to type Ⅱ and 82 to type Ⅲ, which coincided with the different fractures treated surgically or nonsurgically. All surgical and nonsurgical treatments got satisfactory outcome. Conclusion The classification of PDA is effective in guiding the treatment choice for mandibular condyle fractures. Both surgical and nonsurgical treatment can obtain effective results for corresponding case.

BACKGROUND:The research and development of scaffold materials is the key to tissue engineering, as the scaffold can provide a stable external environment for cell growth.OBJECTIVE:To summarize the clinical advances in tendon tissue engineering materials.METHODS:We searched CBM, CNKI, CSTJ and PubMed database for relevant articles published from January 2004 to May 2016. The keywords were tissue engineering, tendon injuries, biological scaffold, tendon healing in Chinese and English, respectively.RESULTS AND CONCLUSION:The commonly used tissue engineering tendon materials include natural polymer materials, biological derivatives, synthetic materials and composite materials. Natural polymer materials retain the three-dimensional network structure of the normal tissue, with good biocompatibility but poor mechanical properties and degradation speed. Synthetic polymer materials present with good mechanical properties and biodegradability, but have low hydrophilicity and poor cell adhesion capability. Composite materials as an effective combination of the two above-mentioned materials exhibit a certain potential in clinical practice. Biological derivatives come from organisms, and have a net structure and biomechanical properties most similar to the human body after appropriate treatment. Additionaly, these derivatives also have the normal physiological activity and functions, which are considered as the future development direction of biomedical materials.

Objective To investigate the efficacy and safety of montelukast sodium combined with fluticasone propionate in treatment of children with cough variant asthma.Methods Two hundred and forty children diagnosed as cough variant asthma in our hospital during February 2013 to January 2015 were randomized into three groups.Children in group Mon + Flu were given montelukast sodium combined with inhaled fluticasone propionate,children in group Flu was given inhaled corticosteroids alone and children in group Mon was given montelukast sodium alone.Cough,lung function and adverse reactions were observed after 8 and 12 weeks of treatment and the recurrences of cough symptoms were followed up within 24 weeks.Results After 8 weeks of treatment,the score of cough in group Mon + Flu (1.1 ± 0.7) was lower than those in groups Flu (1.7 ±0.8) and Mon (1.6 ±0.8) (t =4.973,4.353,P ＜0.05),while there was no significant difference between group Flu and group Mon(t =0.560,P ＞ 0.05).Meantime,the percentage of predicted in FEV1 in group Mon+ Flu (93.4 ± 15.8) was significantly higher than those in group Flu (87.4 ± 11.0) and group Mon (86.5 ± 9.8) (t =2.804,3.315,P ＜ 0.05).The percentage of predicted in PEF in group Mon + Flu(89.8 ± 15.4)was significantly higher than those in group Flu(84.9 ± 13.4)and group Mon(85.1 ± 12.3) (t =2.126,2.124,P ＜ 0.05),and there was no significant difference between latter two groups (t =0.525,0.082,P ＞ 0.05).After 12 weeks of treatment,there was no significant difference in scores of cough and percentage of predicted in FEV1 and PEF among three groups (P ＞ 0.05).There was no significant difference in incidence of adverse reactions among three groups (x2 =1.026,P ＞ 0.05).The recurrence rate of group Mon + Flu (3.85％) and group Flu(5.26％) were significantly lower than that of group Mon (17.33％) (x2 =7.428,5.505,P ＜ 0.05),while there was no difference between groups Mon + Flu and Flu (P ＞ 0.05).Conclusions For children with cough variant asthma montelukast sodium combined with fluticasone propionate has better efficacy than monotherapy in 8 weeks of treatment,but there was no difference in 12 weeks of treatment.The recurrence rate in group Mon + Flu and group Flu is lower than that in group Mon.
