Objective To investigate the application of ear endoscope in the treatment of secretory otitis media in children with ineffective drug therapy.Methods 80 secretory otitis media children with ineffective drug therapy were selected as the research subjects.According to the random number table method,all patients were divided into treatment group and control group,40 cases in each group.The observation group received otoendoscopic tympanic membrane tube surgery treatment,the control group received auripucture with otic endoscope surgery treatment.The complications of the two groups were observed,and the clinical curative effect and postoperative recurrence were compared.Results The recurrence rate of the observation group was 5 .00%,which was significantly lower than 20.00% of the control group (χ2 =4.114,P=0.042).The middle ear effusion time of the observation group was (8.53 ±1.25)d,which was significantly shorter than (10.46 ±1.44)d of the control group (t=5.074,P=0.000). In the observation group,37 patients after treatment had change,the total effective rate was 92.50%.In the control group,28 patients after treatment had change,the total effective rate was 70.00%,the total effective rate of the observation group was significantly higher than the control group,the difference was statistically significant (χ2 =6.646,P=0.009).The incidence rate of complication in the observation group was 7.50%,which was significantly lower than 32.50% in the control group (χ2 =7.812,P=0.005 ).Conclusion Tympanostomy tube under ear endoscope surgery for the treatment of drug refractory secretory otitis media in children has good effect,the recurrence rate is relatively lower,has less complications,high safety,it is worthy of clinical application.

The ZHENG (syndrome of traditional Chinese medicine) oriented effects and the multiple-targets' mechanism are the main challenges encountered by recent researches for Chinese herbal formula. Using methods of bioinformatics and systems biology, we proposed a biological network-based framework for understanding the mechanism of Chinese herbal formula, and reviewed our studies under this framework which aimed to explore the relationship between Chinese herbal formula and corresponding ZHENGs, as well as the synergism of herbal combinations. These studies include the network construction for cold or heat ZHENG and its relationship with herbal formula of hot or cold nature, the biological network construction of angiogenesis, and the network regulation-based emergent property of an herbal combination with anti-angiogenesis synergism extracting from the cold formula. It is shown that the ZHENG-oriented effects and the herbal synergism can be nicely explicated by such network-based approaches. Thus, the network-based drug combination discovery, as well as the "traditional Chinese medicine bioinformatics (TCMB)" and "TCM computational systems biology" combining with computational and experimental approaches, is conceivable and can open a new avenue for understanding Chinese herbal formula.

Objective To evaluate the clinical efficacy of low molecular weight heparin in treatment of patients with severe community-acquired pneumonia (CAP).Methods PubMed, BMA, EMbase, ASP, Cochrane Library, EMCC, CBM, CNKI, CECDB, CQVIP, and VIP databases were searched to identify the relevant randomized clinical trials (RCTs) from the publications during the period from January 1994 to January 2014. The search terms were “low molecular heparin”, “severe community-acquired pneumonia”, “prognosis” in both Chinese and English. The quality of the included studies were strictly evaluated and data were extracted. Stata/SE version 12 software was used for systematic review and meta-analysis.Results Six RCTs were ifnally qualiifed in the analysis, including a total of 208 cases in treatment group and 196 cases in control group. The patients in control group received conventional therapy, while the patients in treatment group received low molecular weight heparin by subcutaneous injection as add-on to conventional therapy. Meta-analysis showed that after treatment with low molecular weight heparin for 7 days, the APACHE II score of severe CAP patients signiifcantly decreased (P = 0.43,I2 = 0%, SMD = -0.70, 95%CI: - 0.90, -0.49) with controllable publication bias (bias_p = 0.93, bias_95CI: -6.79, 6.37). The PaO2 of severe CAP patients signiifcantly increased (P = 0.858,I2 =0%, SMD = 0.51, 95%CI: 0.30, 0.72) with controllable publication bias (bias_p =0.770, bias_95CI: -4.82, 5.90). However, after low molecular weight heparin treatment for 7 days, the PaCO2 of severe CAP patients did not change significantly (SMD = -0.17, 95 %CI: -0.38, 0.04).Conclusion Low molecular
weight heparin is beneifcial in the treatment of severe CAP patients in terms of signiifcantly decreased APACHE II score, increased oxygenation, and improved clinical symptoms.

Traditional Chinese medicine(TCM),a comprehensive medicinal system,is characterized by holistic theory that emphasizes the regulation of the integrity of the human body and the interactions between human individuals and their environments. The diagnostic and therapeutic methods of TCM are based on the differentiation of syndrome(Zheng in Chinese)and the use of herbal formula(Fang-Ji in Chinese). There is an urgent need to develop scientific research methods in accordance with the above characteristics for TCM modernization. In the era of big data and with the rapid progress in systems biology,polypharmacology and bioinformatics,network pharmacology has emerged as a promising drug discovery approach that takes the same view as the theory of TCM. This methodology has explored correlations between drugs and complex diseases from the perspective of the holistic theory and has highlighted the paradigm shift from″one drug,one target″to″network target″. Thus,it is an original idea to combine network pharmacology with the modern research of TCM. This paper briefly analyzed and discussed the progress and major scientific challenges in network pharmacology applied to TCM diagnosis and treatment. To promote the development of TCM network pharmacology , several suggestions were also raised.

Obesity is a developing public health issue. As a core organ in energy storage and metabolic modulation, adipose tissue becomes an important target in body weight control. Total caloric intake limitation and /or macronutrient ratio regulation are commonly used in obesity therapy. The anti-obesity agents derived from adipocyte products may bring us new ways more suitable to physiological status in the future.

Pregnancy associated breast cancer(PABC) is a special kind of breast cancer,it is difficult to diagnose at early stage since the mammary epithelial cells are actively proliferative.Whether pregnancy will affect the biological behavior of breast cancer and how the treatment strategy for the patients with PABC impact on the outcome in terms of side effects,response,etc,those factors have to be taken into special consideration.The standard management of PABC still remain controversial.This article summarized the studies on PABC and discusses the advances in the management of the disease.

Background and purpose:Cyclooxysenase-2(COX-2)was first researched in colon caner,and extensively studied in breast cancer.However it was rarely reported in lymph node negative breast cancer.This study assessed the effect of expression of COX-2 in the prognosis of lymph node negative breast cancer and its use as information of COX-2 status to perfect the prognostic mathematic model.Methods:The expression of COX-2 protein was detected by IHC in 119 cases of lymph node negative breast cancer,the survival data was analyzed.Results:Elevated expression of COX-2 was associated with unfavorable distant disease-free survival(74% vs 93.86%).In subgroups by the simple prognostic model PI=size+HER2-2.5?age-CT-0.55?(ER?ET),the 5-year DFS were decreased with subgroups of low-risk,mid-risk and high-risk and the rate of elevated expression of COX-2 was increased with higher risk subgroups.Furthermore,in mid-risk group,the elevated expression of COX-2 was still able to predict poorer prognosis.Conclusion:The information of expression of COX-2 can be used to perfect the simple prognostic mathematic model,thus it would be more effective for treatment of breast cancer with auxiliary lymph nodes metastases.
