Objective To assess the variation of salivary gland function in differentiated thyroid carcinoma (DTC) patients receiving different doses of 131 I therapy in the first.Methods 40 DTC patients were divided into two groups according to the application 131I doses,salivary scintigraphy was performed with 99TcmO4-on DTC patients before and 3months after 131 I therapy.Quantitative analysis of salivary gland function were performed.Results In low dose group,only the uptake ratio of 30min (UR30) of bilateral parotid decreased ( P ＜ 0.05 ) ; but in high - dose group,the uptake ratio of 30min (UR30),excretion fraction ( EF ),excretion rate (ER) of bilateral parotid and submandibular glands were significantly decreased,excretion time(EP) significantly prolonged after 131 I therapy( all P ＜0.05) ;the parotid gland was more severely than the submandibular gland.Conclusion Salivary gland function was damaged of DTC patients receiving different doses of 131I therapy in the first,salivary gland dysfunction correlated well with the administered dose.

Objective To explore ultrasonographic characteristics and prognosis of cesarean scar pregnancy in the ultrasound.Methods To conducted a retrospective study of 8 cases of diagnoses of cesarean scar pregnancy in ultrasound in our hospital from January 2013 to August 2015.All cases had ultrasonographic examinations regularly during the pregnancy and were confirmed placenta increta by cesarean section or prenatal MRI (6 cases).The imaging characteristics of 8 cases of pregnant women in early pregnancy by transvaginal ultrasound,and the positions of gestational sac and chorion frondosum were observed.Ultrasonic follow-up results,numbers of cesarean delivery,final diagnosis,and pregnancy outcome were analyzed.Results Eight cases of patients were diagnosed cesarean scar pregnancy,and all of ceses were diagnosed placenta increta by ultrasound from 11 weeks to 24 weeks of gestation.It was found that the positions of chorion frondosum were located in the lower edge of gestational sac in Two-dimensional ultrasound and the chorion frondosum was covered in cesarean section scar.The echoes of proliferous chorion frondosum were stronger than the rest of chorion leve and decidua reflexa,and the thickness of proliferous chorion frondosum were thicker than the rest of chorion leve and decidua reflexa.In the follow-up ultrasound of 8 cases in the second trimester,the original position of chorion frondosum which covered and the position of placenta were roughly similar.The position of placenta did not move up with the gestational weeks,in addition,appeared as placenta previa and covered in cesarean section scar.Five patients had strong childbearing willing of continue to conceive,one case of which needed hysterectomy,four of which underwent cesarean section delivery with alive births after using bilateral iliac arteries balloon occlusion.The rest 3 cases underwent induction of labor after using bilateral iliac arteries balloon cclusion.Conclusions Cesarean scar pregnancy in first pregnancy may be develop as placenta accreta in second and third trimester pregnancy.If chorion frondosum was observed to cover cesarean section scar by ultrasound in early pregnancy,scar pregnancy diagnosis was established.Pregnant women who have strong willing to continue their pregnancy should be pay more attentin to thiers placenta previa and placenta percreta in second and third trimester pregnancy.Close follow-up are needed.

Objective To investigate the bacterial distribution and antibiotic resistance profile in Tongling People's Hospital during 2016.Methods All the clinically isolated bacterial strains in Tongling People's Hospital during 2016 were identified and tested for their susceptibility to antimicrobial agents.The results were analyzed with WHONET 5.6 software.Results A total of 2 949 strains of bacteria were collected,including 2 134 strains of gram-negative bacteria and 815 strains of gram-positive bacteria.The top five gram-negative bacteria were E.coli,4.baumannii,K.pneumoniae,P.aeruginosa and Enterobacter.The top five gram positive bacteria were coagulase-negative Staphylococcus,S.aureus,E.faecalis,E.faecium and Streptococcus.The prevalence of ESBLs-producing strains was 42.3％ in E.coli and 31.1％ in K.pneumoniae,The prevalence of carbapenem-resistant strains was 1.2％ (8/640) in E.coli isolates and 29.4％ (108/367) in K.pneumoniae isolates.Majority (94.3％) ofA.baumannii strains were susceptible to tigecycline.However,74.3％ and 74.9％ of these strains were resistant to imipenem and meropenem,respectively.Most P aeruginosa strains (78.2％) were resistant to piperacillin,but about 70％ were susceptible to carbapenem antibiotics.The prevalence of methicillin-resistant strains was 32.0％ (74/231) in S.aureus and 65.6％ (170/259) in coagulase-negative Staphylococcus.No staphylococcal strains were found resistant to teicoplanin or vancomycin.No enterococcal isolates were resistant to teicoplanin or linezolid.Conclusions The number of bacterial isolates in this hospital is increasing year by year.The prevalence of multidrug-resistant bacteria is also on rise,especially the pandrug-resistant Enterobacteriaceae and A.baumannii.It is urgently required to strengthen the control of hospital infections.

OBJECTIVE: To evaluate diagnostic significance of the noninvasive and objective 320-slice CT scan in the high pharynx resilience in the patients with obstructive sleep apnea/hypopnea syndrome. METHOD: Fifty patients with OSAHS and 10 patients with pharyngeal paraesthesia were included in the study. 320 slice CT scan was used to measure the sagittal diameters, transverse diameters and sectional area of the retropalatal region, retroglossal region. Calculating the pharynx wall resilience. Analyzing the correlativity of pharynx wall resilience, BMI and AHI. Fiber endoscope was used to assess the subsidence percentage of the pharynx wall. RESULT: Between OSAHS patients and pharyngeal paraesthesia patients, there was obviously difference in the retropalatal region and retroglossal region upper airway. The pharynx wall resiliences of retropalatal region were much more than that of retroglossal region. The later pharynx wall resiliences were much more than the fore-to-aft pharynx wall resiliences in the retropalatal region. BMI, AHI and the pharynx wall resilience were positive correlative to each other. But AHI and the pharynx wall resilience was nonlinear correlative. There was a good concordance between the pharynx wall resilience detected by 320CT and subsidence percentage of the pharynx wall detected by fiber endoscope. CONCLUSION 320 slice CT is a kind of simple, rapid and objective method to localize the high resilience area of upper respiratory tract, which can be benefit to the clinical diagnosis, the etiological study and the treatment of OSAHS. Based on physical examination, we propose that only one time of CT scan to the patients' upper airway at the Muller' stage is enough to localize the stenosis area, which can reduce radiation dosage dramatically.

Objective To explore the clinical significance of colonoscopy follow-up in Chinese Lynch syndrome mismatch repair (MMR) gene mutation carriers.Methods The results of colonoscopy follow-up was analyzed in 194 MMR gene mutation carriers of 50 Lynch syndrome families.The follow-up period was from April 2001 to November 2016.The detection rates of advanced adenomas and colorectal cancers,five-year survival rate and ten year survival rate were compared between 123 patients of regular follow-up group (colonoscopy interval less than two years) and 71 patients of irregular follow-up group (time colonoscopy interval more than two years).T test,chi-square test and Kaplan-Meier method were performed for statistically analysis.Results The incidence of colorectal cancer of irregular follow up group was significantly higher than that of regular follow-up group (57.7％,41/71 vs 22.8％,28/123);and the difference was statistically significant (x2 =24.00,P＜0.01).The average age at diagnosis for colorectal cancer in irregular follow up group was younger than that of regular follow up group ((45.3 ± 1.9) years vs (48.7±1.8) years);and the difference was statistically significant (t=4.10,P＜0.01).In regular follow-up group,28.6％ (8/28) advanced-stage colorectal cancer (TNM Ⅲ or Ⅳ) was found,while in irregular follow up group,73.2 ％ (30/41) advanced-stage colorectal cancer was found,and there was statistically significant difference in pathological stage between two groups (x2 =4.90,P =0.032).The five year and ten-year survival rates of regular follow-up group were 96.2 ％ and 85.1 ％,respectively,which were both higher than those of irregular follow-up group (46.3 ％ and 28.7 ％);and the differences were statistically significant (x2 =13.20 and 14.80,both P＜0.05).The incidence of advanced adenomas of irregular follow up group was significantly higher than that of regular follow-up group (49.3％,35/71 vs 18.7％,23/123);and the difference was statistically significant (x2 =20.10,P＜0.05).The detection rate of advanced adenomas of MMR gene mutation carriers was higher than those without MMR mutation gene (85.4％,35/41 vs 14.6％,6/41);and the difference was statistically significant (x2 =5.20,P＜ 0.05).Conclusion Regular colonoscopy surveillance may decrease the incidence and mortality of colorectal cancer in MMR mutation carriers of Lynch syndrome families,and increase five-year and tenyear survival rates.

BACKGROUND: Although intensively studied in patients with cardiovascular diseases (CVDs), the prognostic value of diastolic blood pressure (DBP) has little been elucidated in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This study aimed to reveal the prognostic value of DBP in AECOPD patients. METHODS: Inpatients with AECOPD were prospectively enrolled from 10 medical centers in China between September 2017 and July 2021. DBP was measured on admission. The primary outcome was all-cause in-hospital mortality; invasive mechanical ventilation and intensive care unit (ICU) admission were secondary outcomes. Least absolute shrinkage and selection operator (LASSO) and multivariable Cox regressions were used to identify independent prognostic factors and calculate the hazard ratio (HR) and 95% confidence interval (CI) for adverse outcomes. RESULTS: Among 13,633 included patients with AECOPD, 197 (1.45%) died during their hospital stay. Multivariable Cox regression analysis showed that low DBP on admission (<70 mmHg) was associated with increased risk of in-hospital mortality (HR = 2.16, 95% CI: 1.53-3.05, Z = 4.37, P <0.01), invasive mechanical ventilation (HR = 1.65, 95% CI: 1.32-2.05, Z = 19.67, P <0.01), and ICU admission (HR = 1.45, 95% CI: 1.24-1.69, Z = 22.08, P <0.01) in the overall cohort. Similar findings were observed in subgroups with or without CVDs, except for invasive mechanical ventilation in the subgroup with CVDs. When DBP was further categorized in 5-mmHg increments from <50 mmHg to ≥100 mmHg, and 75 to <80 mmHg was taken as reference, HRs for in-hospital mortality increased almost linearly with decreased DBP in the overall cohort and subgroups of patients with CVDs; higher DBP was not associated with the risk of in-hospital mortality. CONCLUSION: Low on-admission DBP, particularly <70 mmHg, was associated with an increased risk of adverse outcomes among inpatients with AECOPD, with or without CVDs, which may serve as a convenient predictor of poor prognosis in these patients.
