Objective To evaluate the efficacy of nasendoscopic resection of the inner wall of the maxillary sinus for the treatment of inverted papilloma of the nasal cavity and paranasal sinuses.Methods From January 2002 to December 2006,10 patients with nasal inverted papilloma received nasendoscopic resection of the inner wall of the maxillary sinus in our hospital.The clinical data of the patients were anlayzed retrospectively.Results The operation was completed in all the 10 cases.They were follwed up for 12 to 72 months with a mean of 30 months.Only one of the patients had recurrent papilloma in 1 year after the treatment.None of the patients devleoped epiphora.Conclusions Nasendoscopic resection of the inner wall of the maxillary sinus is feasible for patients with nasal inverted papilloma.By using the procedrue,facial scars can be avoided;moreover,owing to a clear surgical field,the surgeons can completely resect the tumor,and the patients have less trauma and low recurrence rate after the treatment.

Objective To compare the sensitivity and diagnostic features of mammogram (MG) and magnetic resonance imaging (MRI) on diagnosis of breast ductal carcinoma in situ (DCIS) with or without microinvasion (DCIS-MI).Methods From Jan 2012 to Nov 2013,results of MG and MRI from 72 cases of DCIS or DCIS-MI were retrospectively analyzed.Results The sensitivity of MG was 52.8％ (38/72).The sensitivity of MRI was 87.5％ (63/72),among those 76.2％ (48/63)lesions presented as non-mass-like enhancement.Sensitivity of MRI was significantly higher in DCIS-MI than DCIS (84.6％ vs 100％,P =0.027).Logistic regression analysis showed calcifications was an independent factor influencing the sensitivity of MG (OR =23.785,P ＜ 0.001).Conclusions The sensitivity of MRI is higher than MG for the diagnosis of DCIS and DCIS-MI.

Objective To detect the relationship between the pathological degrees of chronic cholecystitis and coincident diseases. Method The pathological degree was divided into mild,moderate and severe degree according to the pathological changes in 442 cases of chronic cholecystitis,and the proliferation of mucosa cell was detected by SP immunohistochemical staining in 105 cases. Results The coincident calculus, polyp, adenoma in the mild chronic cholecystitis were 65.0%,17.1% and 0.5%, respectively. The coincident calculus, polyp, adenoma and malignant neoplasms in the moderate chronic cholecystitis were 70.1%, 19.4%, 3.7% and 2.2%. The coincident calculus, polyp, adenoma and malignant neoplasms in the severe chronic cholecystitis were 88.0%, 26.4%, 24.2% and 9.9%. The positive expression rates of PCNA in mild, moderate and severe chronic cholecystitis were 12.3%, 17.5% and 38.7%, respectively. The results showed that the pathological degree of chronic cholecystitis was obviously related to the coincidence of calculus, polyp, adenoma, malignant neoplasms. Conclusions Severe chronic cholecystitis is a high-risk lesion of gallbladder carcinoma,it should be removed surgically.

OBJECTIVETo analyze the status of acute upper respiratory infection and influenza-like illness (ILI) among community residents in Jinan in 2015, and to make a understand of the patient's medical treatment behavior and influenza vaccination coverage status in 2014.

METHODSBalloting method and convenient sampling method were used to launch a household survey. The residents who had been in Jinan for more than 3 months were selected, to investigate the residents' attack ratio of acute upper respiratory and influenza-like from Jan. 8 to Feb. 7, 2015. Totally, 1 300 persons from 410 families were involved in this survey which recovered 1 241 valid questionnaires with the efficiency of 95.5%. Based on the national age-urban demographic statistics in 2010, the attack rates of acute respiratory infections, influenza-like illness were estimated by the direct standardization method, and the influenza vaccination rates were also calculated in this study. χ(2)-test method was used to compare the different status of incidence and vaccination among residents with different features.

RESULTSThe attack rate of acute upper respiratory infection and influenza-like illness in Jinan from January 8, 2015 to February 7, 2015 were 30.2% (375 cases), and 6.1% (76 cases), respectively, with a standardized rate of 29.1% and 5.4%. 5.3% (66 cases) of the residents have vaccinated with the influenza vaccine inoculation, with an adjusted rate of 3.8%. The attack rate difference of acute upper respiratory tract infections was statistically significant between each age group (χ(2)=17.121, P= 0.002). The 0-4 age group had a highest attack rate (45.4%) of acute respiratory infection, while the 15-24 age group got the lowest (26.5%). 38.9% (146 cases) of patients went for a treatment in hospital. Among them, 37.7% (55 cases) of them selected the county level hospitals for treatment, 37.7% (55 cases) selected the community level hospitals, and 24.6% (36 cases) selected the individual clinic. Significant differences of influenza-like illness attack rate between each age group were also found in this study (χ(2)=76.79, P<0.001). 0-4 age group had the highest attack rate (22.7%). 81.6% (62 cases) of the ILI sought treatment in the hospital, of which 53.2% (33 cases) selected county level hospital or above, and 33.9% (21 cases) selected community hospital, and 12.9% (8 cases) selected the individual clinic.

CONCLUSIONThe attack rate of acute upper respiratory infections among the residents of Jinan was high, whereas that of influenza-like illness was relatively low. 0-4 age group had a higher risk of ILI than other age groups. Most of the cases were likely to take the treatment in large hospitals. In general, the coverage rate of influenza vaccination was relatively low.

Objective To investigate the correlations of P2Y12 gene polymorphisms with clopidogrel resistance and long-term outcome in patients with acute ischemic stroke. Methods From June 2015 to June 2017, consecutive patients with acute ischemic stroke admitted to the Department of Neurology, Nanjing Jiangbei People's Hospital were enrolled. Thromboelastography was used to measure platelet inhibition rate and assess clopidogrel resistance. Polymerase chain reaction was used to assay C34T and G52T polymorphisms of P2Y12 gene. The patients were followed up at 12 months after discharge. The primary outcome was combined outcome of stroke recurrence, myocardial infarction, and death due to cardiocerebrovascular events. Results A total of 214 patients were enrolled, 51 (23.8%) had clopidogrel re-sistance and 29 (13.4%) had major outcome events. One hundred twenty-eight (59.8%) patients were C34T CC genotype and 86 (40.2%) were CT+TT genotype. The proportion of clopidogrel resistance in patients with CT+TT genotype was significantly higher than that with CC genotype ( 76.5% vs.28.8%;χ2=25.672, P=0.001). There were 131 patients (61.2%) with G52T GG genotype and 83 (38.8%) with GT+TT genotype. There was no significant difference in the proportion of clopidogrel resistance between the GT+TT genotype and the GG genotype (43.1% vs.37.4%; χ2=0.534, P=0.465). Multiple logistic regression analysis indicated that age (odds ratio [OR] 1.064, 95%confidence interval [CI] 1.009-1.115;P=0.021), diabetes ( OR 3.773, 95%CI 1.672-8.475; P=0.004), and C34T CT+TT genotype ( OR 9.087, 95%CI 4.416-22.665; P=0.002) were the independent risk factors fot clopidogrel resistance. Cox proportional hazards model analysis showed that age (Hazard ratio [HR] 1.058, 95%CI 1.001-1.121; P=0.049), hypertension ( HR 3.105, 95%CI 1.149-9.523; P=0.028), homocysteine ( HR 1.101, 95%CI 1.020-1.190; P=0.014), and C34T CT+TT genotype ( HR 2.588, 95%CI 1.121-5.967; P=0.026) were independent risk factors for the composite outcome. Conclusion C34T polymorphism of P2Y12 gene in patients with acute ischemic stroke may be a risk factor for clopidogrel resistance and is independently associated with the risk of long-term recurrence of vascular events.

Toll-like receptors (TLRs) is a type of pattern recognition receptors (PRRs), which are singular, non-catalytic and highly homologous. TLRs not only play significant roles in natural immunity, but also act as a bridge between innate immunity and adaptive immunity. Recent studies have revealed that TLRs play critical roles in the development of non-resolving inflammation-related cancer,including the formation of tumor microenvironment, invasion and metastasis, immune escape, etc. Further investigation into the mechanisms responsible for the function of TLRs will be of great value in tumor prevention, early diagnosis and therapy.
