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.

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 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.

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.

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.

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.

Objective:To investigate the therapeutic medication for inpatients with cancer pain, and compare with the latest cancer treatment guidelines to improve the rational drug use. Methods:By a retrospective study, the medical record analysis for the inpatients with cancer from October to December in 2014 was performed, and the incidence of pain and the therapeutic medication were investiga-ted and the rationality of drug use was evaluated based on the latest cancer pain treatment guidelines. Results:The incidence of cancer pain was 25. 46% of 774 cases with new cancer, and 76. 58% of the patients with cancer pain were treated with analgesic drugs. In ac-cordance with the guidelines for the treatment scheme, there was no significant difference between the Opioid-Naive group ( guide group 1) and the Opioids-Tolerant group (guide group 2) in the combination therapy, while there was significant difference in the drug selec-tion and the time of administration. In the guide group 1 the proportion of oxywdone controlled-release tablets was signiticantly higher than that in the guide group 2, the ratio of taking the medicine on time in the guide group 1 was also higher than that in the guide group 2. Both groups showed difference from the guidelines in the pain assessment and titration and specific analgesic drug use. Conclusion:The findings indicate the difference between the pain treatment and the guidelines in therapeutic medication of cancer pain, and the propaganda and education of relevant knowledge should be strengthened to promote the treatment standard.

Objective To investigate the diagnosis and surgical management of Hashimoto's thyroiditis and coexisting disease. Methods The clinical data of 54 patients with Hashimoto's thyroiditis were analyzed retrospectively. Results 25 cases were diagnosed as Hashimoto's disease by clinical physical examination, FNAB and immune antibody assay. Diagnostic treatment with medicine was adopted firstly. Of them 24 cured, one was found coexisting thyroid cancer, and then a radical operation was performed. The other 29 cases had been misdiagnosed as surgical diseases because of atypical features and undergoing thyroidectomy; the diagnosis of Hashimoto's disease had been confirmed by pathology, and some coexistence had been found(hyperthyroidism in 3, thyroid carcinoma in 4, malignant lymphoma in 2, thyroid adenoma in 5). Conclusions Attention should be paid to the atypical Hashimoto's disease. FNAB, immune antibody assay, diagnostic treatment, operative exploration and biopsy would be helpful to make the sound diagnoses of Hashimoto thyroiditis and the disease in coexistence, which ought to be operated on corresopondingly.
