Objective To compare the changes of corneal endothelial cells in early recovery period after 1.8 mm small incision phacoemulsification nucleus chopping and conventional incision phacoemulsification for cataract.Methods Fifty-three patients with cataract were divided into the observation group and control group according to different operation methods.The observation group was treated with 1.8 mm small incision phacoemuisification nucleus chopping while the control group was treated with routine incision phacoemuisification.The visual acuity,degree of astigmatism,corneal endothelial cell indexes and complications were observed.Results The effective ultrasound time and average ultrasonic energy of the observation group were significantly less than those of the control group (all P ＜ 0.05).Compared with 1 day before operation,the visual acuity,degree of astigmatism,corneal endothelial cell area (ECA) and coefficient of variation (CV) were significantly increased at 1 week and 4 weeks after operation,and corneal endothelial cell density (ECD) was significantly decreased (all P ＜ 0.05).The visual acuity and ECD levels of the observation group at 1 day,1 week and 4 weeks after operation were significantly higher than those of the control group,while the degree of astigmatism,ECA and CV were significantly lower than those of the control group (all P ＜ 0.05).Conclusion Compared with the traditional incision phacoemulsification,the damage of 1.8 mm small incision phacoemulsification nucleus chopping to corneal endothelial cells is significantly milder,can reduce the effective ultrasound time and average ultrasonic energy,decrease the degree of astigmatism,improve the visual acuity and decrease the corneal edema.

Through the questionnaire survey of 2,000 patients with dysmenorrhea, the clinical characteristics of dysmenorrhea were investigated, and the reference basis for preventing and controlling dysmenorrhea was provided. The results found that the age of menarche, short menstrual cycle, by volume, long period of time has no obvious relationship with the occurrence of dysmenorrhea. Dysmenorrhea main influence factors to feel cold; syndrome (symptoms) characteristics for the actual situation inclusions mainly, with severity, deficiency symptoms more obvious; in different degrees of dysmenorrhea, frequency of belly chills symptoms appear most, and cold coagulation and blood stasis syndrome (symptoms) appear higher frequency; The type of cold coagulation and blood stasis dysmenorrhea was 53.2%. Dysmenorrhea measures to select bed rest most, accounting for 79.6%. For severe dysmenorrhea in patients with drug choice to traditional Chinese combined with western medicine accounted for 43.4%. Selection of Chinese medicine formulations in patients with dysmenorrhea Decoction formulation accounted for the most 26.5%. The survey results, to avoid cold and have a positive effect on the prevention of dysmenorrhea, dysmenorrhea treatment should pay attention to warming channels to dispel cold.

0.05),including seven with spinal kyphosis,seven with thoracic deformity,five with pleural effusion,five with emphysema diagnosed by chest X-ray film,three with spontaneous pneumothorax,two with diaphragmatic hernia,and one developed severe respiratory failure and the other developed cot pulmonale.Conclusions The thorax,lungs and diaphragm were more easily involved in the patients with Marfan syndrome,and pulmonary specialists should keep an eye on them.

OBJECTIVE:To establish the quality standard of Yanyan pills.METHODS: The constituents such as Lysimachia christinae,Radix et Rhizoma Glycyrrhizae and Radix Astragali were identified qualitatively by TLC,and the content of caffeotannic acid in L.christinae was determined by HPLC.RESULTS: The TLC spots were distinctive and well-isolated.The linear range of caffeotannic acid was 0.036～0.18 ?g(r=0.999 9)with an average recovery of 100.8%(RSD=0.67%,n=6).CONCLUSION: The established standard is applicable for the quality control of Yanyan pills.

OBJECTIVE To analyze the pathogens of severe pneumonia induced by different underlying diseases in(hospital) and to evaluate the difference of the pathogens to antimicrobial susceptibility test.METHODS The(bacteria) through sputum culture with VITEK-AMS,and the antimicrobial susceptibility against(bacteria) by K-B method were tested in hospital from 2002 to 2005.RESULTS There were 106 patients with 173 strains of isolated(pathogenic) bacteria,including Klebsiella pneumoniae(KPA) 20.9%,and Escherichia coli(ECO)(16.3%) from the aspiration severe pneumonia;Pseudomonas alcaligenes(PAL) 18.9%,P.aeruginosa(PAL)(16.2%) and Staphylococcus aureus(SAU) 16.2% from the obstructive severe pneumonia;KPN 22.6%,SAU(18.9%),and PAE 17.0% from the COPD complicated with severe pneumonia and PAE 25.0% and SAU 20% from the(hospital-)acquired pneumonia(HAP).CONCLUSIONS The constructed ratio of pathogens is different between(severe) pneumonia infected by different underlying diseases and community-acquired pneumonia without any(underlying) disease.The resistant pathogens are increasing significantly in cases with HAP.

Objective To preliminarily explore the delineation of clinical target volume in intensity-modulated radiotherapy for para-aortic lymph node metastases in patients with gynecological malignancies.Methods A retrospective analysis was performed on 56 gynecological tumor patients with para-aortic lymph node metastases who were admitted to our department from January 2010 to September 2016.The number and distribution of metastatic para-aortic lymph nodes were determined by imaging method.Results A total of 108 positive para-aortic lymph nodes were found in the 56 patients,with 1-4(mean,2) positive para-aortic lymph nodes per patient.The mean diameter of positive para-aortic lymph nodes was 2.3 cm (1.2-4.0 cm).A total of 20 metastatic lymph nodes (19%) were located at the L4 level,38(35%) at the L3 level,44(41%) at the L2 level,and 6(5%) at the L1 level.There were 71 metastatic lymph nodes (66%) at the left side of the para-aortic region,20 metastatic lymph nodes (19%) between the abdominal aorta and the vena cava,and 17 metastatic lymph nodes (15%) at the right side of the inferior vena cava.Conclusions For patients with gynecological malignancies,nodal contouring for the para-aortic region should not be defined by a fixed circumferential margin around the vessels.The left side of the para-aortic region should be covered adequately;the upper target should be extended up to the renal artery,and needs to be further extended for patients who have nodal involvement near the renal arteries and veins.

Objective To carry out the urban community residents satisfaction investigation and analyze the present situation of public service of medical institutions,to discuss under the new situation,the development of medi-cal and health innovation mechanism,thus to meet the multi -level and diverse people health services demand. Methods Random stratified sampling of Qingdao city community residents,1 430 people,adopted the method of the questionnaire about the present situation of public hospital and community health service center and the satisfaction was investigated.Results Of Qingdao city community residents,1 430 people chose to large public hospital patients (65.8%),community health service centers (37.3%).In a large public hospital from visits to the end,took at least half a day to account for 69.5%,more than a day (18.7%);Unreasonable process part (45.2%),such as hospital formalities complex,paper take inconvenient,medical guide was too little,expert outpatient service limit number,to see the doctor for a long time,adjust time was shorter,the doctor for the patient and the lack of patience,etc.The process was reasonable and convenient accounted for 40.0%.Think of large public hospital service attitude,subject to further improvement accounted for 58.2%;Think good service attitude,the very satisfied accounted for 30.7%.Think that community health service center service attitude good,very satisfied accounted for 43.2%;Think the service attitude in general,efficiency was 37.9%.96.1% of the respondents believed that society should form a public -private joint diversified do medical pattern,provided residents with various preferential policies.98.4% of the respondents expected countries to optimize the medical service resources allocation,promoted resources with high quality and the countryside in poor areas.Conclusion At present,most of the patients choose to large public hospital,process and service attitude is the key of the need to improve.Large public hospitals and community health service center should strengthen the cooperation and formation mechanism of innovation and development,and make the patients more options,so as to get better medical service quality.
