Objective To investigate the clinical data of Mycoplasma pneumoniae pneumonia(MPP)compli-cated with embolism in children,and to improve the understanding of the clinical features,diagnosis and treatment of the disease.Methods Six cases of MPP complicated with embolization,who were treated at Nanjing Children′s Hospital Affiliated to Nanjing Medical University from January 201 0 to June 201 5,were analyzed retrospectively.Results The ages of 6 cases ranged from 3 years and 3 months old to 1 3 years and 1 0 months old,and 3 cases were boys,3 cases were girls.All of 6 patients had high fever,positive anti -Mycoplasma IgM antibody (≥1 160)and sputum fluores-cence quantitative -Mycoplasma pneumonia (FQ -MP DNA),and all the chest imaging was consistent with pneumonia. Among 6 patients,4 cases complicated with liver function damage,4 cases had D -dimer rise,5 cases of erythrocyte sedi-mentation rate increased at different degree,while pleural effusion or pleuritis was found in 5 cases.The region of embo-lism in the cases included left renal artery in 1 case,the left popliteal artery in 1 case,the right middle cerebral artery em-bolism combined with cerebral infarction in 1 case,the right subclavian vein embolism combined with right upper extremi-ty embolism in 1 case,the basilar artery and bilateral posterior cerebral artery embolism combined with cerebral infarction in 1 case,and the other case involved the right pulmonary embolism.One case received thrombus dislodgment operation, and all of 6 cases were given the treatment including anti -infection,anticoagulation and low dose of glucocorticoid the-rapy,among whom 1 case died of cerebral hernia,and the other 5 cases improved.Conclusions MPP is often complicated with hypercoagulative state and potentialized to thrombosis,and thrombus may occur in vessels of whole body organs,and cerebral infarction had poor prognosis.Consequently,doctors should be aware of the potential risk factors for thrombosis. Early diagnosis and prompt anticoagulation and thrombolytic therapy could reduce mortality and disability rate.

Background and purpose:Increasing thyroid cancer (TC) incidence has caused wide public concern. It is typically interpreted as an increase in the true occurrence of TC but may also relfect changing life style or aging of population or increased diagnostic scrutiny. This study describes the temporal trend for incidence of TC and survival rate of patients by summarizing the 41 years TC incidences and follow-up data in Xuhui District, Shanghai.. Methods:Annual TC incidence data of Xuhui District from 1973 to 2013 were provided by Shanghai Cancer Registry System. The calculation of age-standardized incidence rates (ASIR) was based on the population of the year 1973. Temporal trends in TC incidence were analyzed based on the natural spline regression model. Annual percentage change (APC) was estimated by Jointpoint software from US National Cancer Institute, as well as survival rates were estimated using Kaplan-Meier method by Stata software.Results:During the period from 1973 to 2013, papillary cancer was the dominant type with proportion 69.8%. The ASIRs for female TC were 2.51-2.70 times as high as those for male TC. The average age of TC incidence for male was 50.04±14.71 while for female was 48.57±13.65. When aging factors were removed, incidence rate of TC was on the rise since 1981 with the APC of 8.46% (95%CI: 5.9%-11.1%), and on a rapid growth from 2004 to 2013 with the APC of 20.30% (95%CI: 9.8%-31.7%). The study showed that the 5-year TC survival rate was 95.21%, and the 10-year TC survival rate was 89.09%. In addition, survival rate of female was higher than that of male (χ2=15.43,P=0.000 1).Conclusion:The rising trend of TC in Xuhui District is similar to those in Shanghai and some developed countries. Although the mortality rate of TC is low, it has a rapid increase in incidence. Studies on factors associated with TC will help to clarify the epidemiological features about TC and promote more eff-cient prevention and control strategies.

Objective To investigate the improvement role of aspirin combined with statins on carotid plaque of patients with cerebral thrombosis.Methods80 cases of patients with cerebral thrombosis in our hospital from May 2014 to May 2016 were selected, these patients were divided into aspirin combined with statins treatment group (combined treatment group, 40 cases) and single aspirin treatment group (single treatment group, 40 cases) two groups according to the treatment methods, the NIHSS scores, Barthel indexes, clinical curative effects, IMT, plaque areas of the two groups were statistically analyzed.ResultsThe NIHSS score of the combined treatment group was significantly lower (P<0.05), the Barthel index was significantly higher (P<0.05), the total treatment efficiency 95.0% (38/40) was significantly higher than the single treatment group 80.0% (32/40) (P<0.05), the IMT was significantly shorter (P<0.05), the plaque area was significantly smaller than the single treatment group (P<0.05).ConclusionAspirin combined with statins can more effectively improve the carotid plaque of patients with cerebral thrombosis than aspirin alone, so is worthy of promotion and use in the clinical.

Objective To investigate the cataract patients' awareness on the cataract diseases, treatment and major obstacles for patients to seek eye care. Design Prospective cross-sectional study. Participants All 251 patients in Jiangyan county were screened by the group of eye diseases selection in 6 months for cataract treatment performed by prevention blind surgery group. Methods Patients accepted surveys before operation. The patient's awareness questionnaire was developed in Aravind Eye Hospital, India. Main outcome measures Awareness of eye disease, awareness of treatment, obstacles of therapy and false treatment. Results 89.6% of patients were aware of the occurrence of eye disease for more than 1 year. However, it was only 0.12% of patients when they realized that their eye diseases could be treated more than 1 year,the time less than 6 months was 31.9%,and the time less than 1 month was 65.7%. The major obstacles for seeking eye care were still able to see a little, economic reason, no demand for operation, short of belief for the operation, etc. Conclusions It's high necessary and imperative to educate patient the knowledge of eye health and care. Developing economy is the radical measure in a long run to improve the cataract surgical rate (CSR) in our country. Low price service and high quality surgery is the key of improving CSR at present.

Objective To investigate the trends of colorectal cancer incidence in Shanghai Xuhui District from 2001 to 2011.Methods Total 3042 cases of colon cancer and 1958 cases of rectal cancer were collected from the Shanghai Cancer Reporting System.The results were age-adjusted according the census data of 2000 as the standardized incidence.Results The standardized incidence rate of colorectal cancer in Xuhui District rose from the 21.83/100 000 in 2001 to 27.35/100 000 in 2006 and increased by 25.29％ ; from 2009 to 2011 the incidence rate was stabilized.The ratio of colon to rectal cancer was 1.55:1,and the incidence of colon cancer was significantly higher than rectal cancer.The incidence rate of male and feinale colorectal cancer increased with age,especially at ＞ 45 y group accounting for 98.70％ and 98.37％ of total incidence rate respectively.The ratio of male to female in colon cancer incidence rate was 0.98∶ 1,while that of rectal cancer was1.25∶ 1.Conclusion The incidence of colorectal cancer in Xuhui District from the last 11 years is significantly higher than of national level.More effective preventive measures should be taken.

The paper is aimed to provide a novel index, named as multidimensional spatial triangular area, for the evaluation of the release-absorption correlation of multiple component traditional Chinese medicines (TCMs). The applicability of the method was demonstrated by the example data. The method and standard practice for evaluation of the release-absorption correlation for western medicines with single compound could not be applied to TCMs with multiple components. The release percentage or absorption percentage of the multiple components for TCMs at the sampling time was a point in the multidimensional space. The area of the triangle formed byt the sequential three points rrepresented the changing characteristics of the components' release and absorption kinetics. The side lengths of the triangle could be calculated from the spatial distances between each two of the sequential three points. Then the triangle area could be obtained by the side lengths. The in vitro release-in vivo absorption correlation of the multiple components could be represented by the correlation between the integrating values of the release triangle areas and that of the absorption triangle areas. The results of the examples indicated that the multidimensional spatial triangular area method could treat the multiple components in a holistic way, in line with the holism the hi he TCMs. Therefore, the multidimensional spatial triangular area method provided new methodology for the release-absorption correlation of the TCMs with multiple components.

AIM: This study is to detail its possible mechanisms that homocysteine (Hcy) induces injury of cultured endothelial cells.METHODS: Hcy in sequential concentrations was added into the cultured human umbilial vein endothelial cells for 24 hours in serum-free medium. The lipid peroxidation, release of LDH, cell total protein content, cell apoptosis and necrosis were assessed. RESULTS: Hcy increased the apoptosis of endothelial cells.In high Hcy concentration the cells also showed obvious injurious and necrotic morphological changes. Lipid peroxidation increased, with LDH releasing up and cell total protein content down, and they showed a positive dose-effect relationship with the Hcy concentration. All the above effects of Hcy was strengthened by low density lipoprotein (LDL) which may suggest synergetic effects of Hcy and LDL.CONCLUSION: Our results indicate that Hcy has a strong oxidizing effect, which may be one of its major mechanism for injury of EC.

Objective To explore the clinical characteristic,level of plasma renin angiotensin (PRA),plas-ma angiotensin Ⅱ(Ang Ⅱ)and plasma aldosterone(Aldo)in the sleep apnea hypopnea syndrome (SAHS)patients, and to investigate the association between SAHS and hypertension.Methods The patients were selected for the study who were monitored with polysomnography.They were divided into SAHS group and non-SAHS group according to apea-hypopnea index(AHI),and there were 180 patients in the SAHS group,175 patients in the non-SAHS group. The systolic blood pressure(SBP),diastolic blood pressure(DBP)and the level of PRA,plasma Ang II and plasma Aldo were compared by variance analysis.Results The gender composition was different between the two groups,and had statistically significant difference(χ2 =16.30,P <0.01).The data of age,body mass index,neck circumference, waistline,DBP,SBP in SAHS group were significantly higher than those in non-SAHS group,and the differences were statistically significant(t =6.84,8.19,9.84,6.63,7.08,5.45,all P <0.01 ).The prevalence of hypertension in SAHS group was 46.58%,which was higher than 18.20% in non-SAHS group,and the difference had statistically significant(χ2 =46.71,P <0.01).The AHI had positive correlation with SBP,DBP,and they had statistically signifi-cant differences (rs =0.162,0.228,all P <0.01).The levels of PRA and plasma Ang Ⅱ were lower in SAHS group than those in non-SAHS group,while the level of plasma Aldo was higher in SAHS group than that in non-SAHS group,and had statistically significant differences(F =15.41,14.21,17.67,all P <0.01).In the SAHS group,the levels of PRA and plasma Ang Ⅱ were lower in hypertension group than those in non-hypertension group,while the level of plasma Aldo was higher in hypertension group than that in non-hypertension group,and had statistically signif-icant differences (F =15.41,14.21,17.67,all P <0.01).Also,the levels of PRA and plasma Ang Ⅱ were lower in SAHS group with hypertension than those in non-SAHS group with hypertension,while the level of plasma Aldo was higher in SAHS group with hypertension than that in non-SAHS group with hypertension,and the differences were sta-tistically significant(F =15.41,14.21,17.67,all P <0.01).Conclusion The occurrence of SAHS is correlated with the gender composition,age,body mass index,neck circumference,waistline,DBP and SBP.In SAHS complica-tions in each system,the highest incidence is hypertension.And the AHI has positive correlation with SBP,DBP,and the difference is significant.In the SAHS group,if the AHI is higher,the risk of hypertension is greater.In the SAHS patients with hypertension,the level of plasma Aldo is significantly elevated,while the levels of PRA and plasma AngⅡ are decreased significantly.
