The dark-adapted efectroretinogram (ERG) was investigated in 67 diabetic patients (124 eyes) and in 50 normal subjects (75 eyes). The results showed that the rate of reduced amplitudes and lengthened peak times of a, b waves, as well as the rate of extingaished oscillatory potentials in diabetics ERG were elevated in sequence from no, mild, moderate to severe retinopathy (P

Objective: To improve the diagnosis and treatment level of secretory otitis media (SOM) of children. Method :Clinical information of 80 children with SOM were colletcted and analysed. All of the 80 cases (144 ears)were treated by myringotomy with Grommet insertion. Among them, 30 cases by adenotonsillectomy. 10 cases by palatoplasty. Secretions of 54 ears were carded out by bacterial culture. Result:80 cases were followed up for 6 to 12 mothes. 120 ears of 144 were cured (83％) ,with hearing improved. The tympanograms and hearing threshold of pure tone were found to be normal. The Gram＇s positive and negative germs of bactevial culture were 20.7％ (6/29 samples ) and 24％ (6/25 samples ) respectively. Conclusion: Children with secretory otitis media should be treated as early as posible to improve the patients＇ hearing and develope their speech.

Objective:To analyze the risk and prognostic of patients with stage ⅠB1 cervical adenocar-cinoma.Methods:The clinical data of 139 patients with stage ⅠB1 cervical adenocarcinoma treated at Department of Gynecology and Obstetrics in Peking University First Hospital from August 1994 to April 2015 were retrospectively reviewed,which included 38 cases of cervical adenocarcinoma and 101 cases of cervical squamous cell carcinoma.A comparison was made between ovarian preserving group and bilateral oophorectomy group,in order to justify the risk and prognosis of ovarian preserving patients.Results:The 5-year cumulative survival rate of stage ⅠB1 cervical adenocarcinoma and squamous cell carcinoma were 89.1% and 92.9% respectively with significant difference (P =0.034).One ovarian metastasis case was observed among the 32 cervical adenocarcinoma patients of bilateral oophorectomy,while another ovarian metastasis case was observed among 54 cervical squamous cell carcinoma patients of bila-teral oophorectomy.The ovarian metastasis rate was 3.1% (1 /32)and 1.8 % (1 /54)respectively with no statistical difference (P =0.574).The cumulative 5-year survival of 6 ovarian preserving patients with cervical adenocarcinoma was 80.1%,while that of 47 ovarian preserving patients with cervical squa-mous cell carcinoma was 94.6% (P =0.127).There was no statistical difference between the survival curve of the two groups.Conclusion:The prognosis of stageⅠB1 cervical adenocarcinomas was somewhat poorer than that of cervical squamous cell carcinoma.However it was still reasonable to perform ovarian preservation among young patients of stageⅠB1 cervical adenocarcinoma with no high risk factors.

Objective To study the relationship between cleft palate and secretory otitis media(SOM)and the change of hearing of cleft palate patients with SOM before and after tube insertion.Methods 203 cleft palate patients(406 ears)were investigated by pure tone audiometry,acoustic immitance audiometry and auditory brainstem response(ABR).21 cleft palate patients with SOM underwent palatoplasty and myringotomy with tube insertion at the same time.Results The incidence of middle ear disfunction was 68.5% in 203 cases with cleft palate,which in the cases under 6 years the incidence was 80%.After operation,21 cases were followed up one to three years,their average hearing improvement was 17dB by tube insertion( P

Objective To investigate the electromyographic(EMG)characteristics of sternocleidomastoid muscle in patients with motor neuron disease.Methods The clinical and EMG data of 461 patients of MND group and 349 of non-MND group were analyzed retrospectively.Results The abnormality rate of sternocleidomastoid EMG in MND group was 60.3%,much higher than that in non-MND group(4.6%)(P

Objective To study risk factors with the occurrence of the mesh exposure after pelvic floor reconstruction.Methods From Mar.2007 to Mar.2011,a retrospective study was made on the clinical data of 353 patients undergoing vaginal mesh pelvic floor reconstruction.The related complications of the mesh were surveyed,and risk factors associated with the mesh's exposure were studied by single factor and multiple factors logistic regression.Results It was found that the exposure rate was 9.6％ (34/353) after 1 year postoperative follow-up.Single factor analysis showed that patients who were not less than 70 years old,patients who were on their menopause stage,the occurrence of not less than three parturition,history of pelvic surgery,diabetes and smoking had a significant correlation (all P ＜ 0.05) with the occurrence of the mesh exposure after pelvic floor reconstruction.Multiple factors logistic regression analysis showed that patients who were not less than 70 years of age (OR =2.389),the occurrence of not less than three parturition (OR =2.688),the history of diabetes (OR =3.545),the history of pelvic surgery (OR =5.385) were the independent risk factors,and the operation experience was the protection factors (OR =0.134).Conclusions Mesh exposure is a common complication after pelvic floor reconstruction.Old age,multiple delivery,history of diabetes and history of pelvic surgery are the risk factors of mesh exposure.Preoperative full assessment and the quality of training contribute to reduce the incidence.

Developing and sharing medical information resources in big data environment play an important role in joint developing and sharing medical information resources in our country.The economic benefits of developing and sharing medical information resources in big data environment were thus elaborated in aspects of their products and service according to their beneficial theory for their rational location.

Big data can provide effective data support for clinical research, biomedical technology progress, and individualized treatment of patients.However, medical ethics and data privacy must be considered due to the poor relation between patients and medical workers .The advantages and disadvantages of big data in medical practice were thus analyzed with certain strategies proposed for their development and privacy protection , and for the balance between the benefits and risks of technological innovations .

Objective To observe the clinical efficacy of ZHU Lian's acupuncture activating method with type 1 manipulations in treating hypotonic cerebral palsy.Method Sixty patients with hypotonic cerebral palsy, aged 9-59 months, were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by ZHU Lian's acupuncture activating method with type 1 manipulations, while the control group was intervened by acupoint injection of vitamin B1 and B12. The two groups were treated once a day, 5 sessions as a treatment course. The Gross Motor Function Measure-88 (GMFM-88) was evaluated before the treatment and after 10 treatment courses.Result The GMFM-88 score was significantly changed after the treatment in both groups (P<0.05). After the intervention, the GMFM-88 score in the treatment group was significantly different from that in the control group (P<0.05).Conclusion ZHU Lian's acupuncture activating method is an effective approach in treating hypotonic cerebral palsy.

Objective To investigate the correlation between expression of four adhesion molecules in sera and in skin lesions of patients with psoriasis vulgaris, as well as their relevance to clinical severity of the disease. Methods Enzyme-linked immunosorbent assay (ELISA) was used to determine the serum levels of ICAM-1, ICAM-3, VCAM-1 and ELAM-1 in 36 patients with plaque type psoriasis vulgaris and 36 healthy controls. Avidin biotin immunoperoxidase staining system was employed to quantitate expression of the four adhesion molecules in psoriatic skin lesions before and after treatment. Results Significantly increased expression of four adhesion molecules was found in psoriatic skin lesions (P
