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 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.

‘Controlling spirit’is the key point of efficacy of acupuncture treatment, which goes throughout the treatment. Both doctor and patient have to understand each other and closely cooperate to get full control of spirit. Try to be carefully to examine the condition and get psychological relaxation before inserting needle, concentrate the spiri and get mind in the needle on inserting needle, give attention to needling sensation after inserting needle, setting the mind to conserve energies and regulate emotion-thought after witherawing needle.To achieve controlling spirit includes understanding spirit, influencing spirit, focus on spirit, and maintaining spirit, then to improve the clinical curative effect and obtain the the best results.

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.

Objective To investigate the relationship between auditory event-related potentials to an oddball task and age in healthy adults,in order to provide the basis for the clinical diagnosis of age-related cognitive diseases.Methods 90 subjects were examined by auditory event-related potentials to an oddball task,and divided into normal young adults,middle-aged and elderly groups (n =30,each group).We measured the wave latencies and amplitude of P50,N100 and P200 wave recorded at the Cz points,and those of N200 and P300 wave at the Pz point.The correlations of the above indicators with age were analyzed.Results The reaction times were (519.33±33.65) ms in youth group,(521.52±39.81) ms in middle age group and (531.46±43.26) ms in elderly group.There were no statistically differences in reaction times among the 3 groups(F=1.89,P=0.107).Compared with the youth group,P50 amplitudes were increased [(2.03±0.31) μV vs.(1.83±0.23) μV,t=2.17,P＝ 0.032],P300 latencies were prolonged [(343.17 ± 30.70) ms vs.(323.54 ± 24.56) ms,t=2.23,P=0.028],P300 amplitudes were decreased [(13.88±3.15) μV vs.(15.62± 2.12) μV,t=2.35,P＝0.018] in the middlc-aged group.Compared with the middle-aged group,the elderly group showed that P50 amplitudes were increased [(2.39±0.40) μV vs.(2.03±0.31) μV,t =4.73,P=0.000],N200latencies were prolonged [(222.16±29.40) ms vs.(206.04±28.98) ms,t=2.12,P=0.039],P300 latencies were prolonged and amplitudes were decreased [(373.83 ± 45.90)ms vs.(343.17±30.70)ms,t=5.12,P=0.000; (10.68±4.16)μV vs.(13.88±3.15) μV,t=4.95,P=0.000].Other waves had no significant differences in latencies and amplitudes among the three groups (all P＞ 0.05).In all subjects,P50 amplitudes and P300 latencies showed positively correlated with age.The average increments of P50 amplitudes and P300 latencies in normal young adults,middle-aged and elderly groups were 0.008 V/year,0.012 V/year and 0.016 V/year,and 0.917 ms/year,1.148 ms/year and 1.715 ms/year respectively.Conclusions In healthy adults,P50 amplitude and P300 latency of auditory event-related potentials are related with age.P50 amplitude and P300 latency are gradually increased or prolonged along with age,with accelerated changes in the elderly.

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.

An increasing numaber of clinical trials have confimed the cholesterol-independent effects of statins.Recent clinical observations have found that using statins before the onset of ischemic stroke and during the acute stage can greatly lessen the severity of neurological defi-cits,reduce the mortality,and improve the prognosis;and that for patients with long-term statius treatmem,who withdraw the drug abruptly,may aggravate stroke lesions,and increase the risk of relapse.Although the use of statius may slightly increase the risk of bleeding,undoubtedly,the use of statins has become one of the most important approaches in the prevention and treatment of ischemic stroke.

Objective To observe the influence of bacterial lysates (broncho-vaxom) combined with montelukast sodium on serum immunoglobulin, interferon (IFN)-γ and interleukin (IL)-4 in asthma and the clinical efficacy. Methods Thirty-one patients with asthma in acute period of onset in children (study group) received broncho-vaxom combined with montelukast sodium for 3 months on the basis of conventional treatment. The changes of serum IgG, IgA, IgM, IFN-γ and IL-4 levels before and after treatment were observed and compared with 31 healthy children (control group), the score changes of day and night symptom were also observed before and after treatment. Results IgG and IgA levels were abnormal significantly in study group before treatment (P < 0.05 ), they were significantly increased after treatment, but IgG was still significantly lower than that in control group (P < 0.05 ). IFN-γ and IL-4 were significantly abnormal in study group before treatment (P < 0.05), IFN-γ was significantly increased after treatment (P<0.05), while IL-4 was significantly decreased (P<0.05); after 3 months of treatment, the score of day and night symptom in study group were (0.4±0.1 ) and (0.7±0.2) scores respectively, which both decreased significantly than those before treatment [(2.6±0.3 ) and (3.4±0.7) scores respectively],the difference were statistically significant(P < 0.05 ). Conclusion Children with asthma have the existence of decreased immune function, application of broncho-vaxom combined with montelukast sodium can effectively control its symptoms and improve immune status.

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.
