Objective: To explore the application of interactive nursing model in children with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods: From July 2015 to August 2017, 110 children with OSAHS admitted to our hospital were enrolled in this study. The patients were divided into two groups (55 cases) according to the digital random table method. Control group routine care, observation group interactive nursing model. Anxiety, pain, treatment compliance and nursing satisfaction were compared between the two groups before and after treatment. Results: The scores of anxiety before operation and at 24h after operation in observation group were (45.01±5.22) points, (50.26±5.44) points and (48.37±5.21) points respectively before operation and (48.87±5.79) points, (56.28±6.03) points and (51.46±5.28) points respectively, the difference was statistically significant (t= 3.672, 5.497, 3.089, P <0.05). The VAS scores of the observation group at 6h and 24h after operation were (4.65±0.78), (2.82±0.51) points in the control group and (5.14±0.73) points and (3.43±0.57) points in the control group (t= 3.402, 5.915, P<0.05) The treatment compliance and nursing satisfaction were 94.55%(52/55) and 96.36%(53/55) respectively, while those in the control group were 74.55%(41/55) and 72.73%(40/55), respectively. The difference was statistically significant (χ²=8.419, 11.758, P<0.05). Conclusions The interactive nursing model applied to children with OSAHS surgery can relieve anxiety, relieve postoperative pain, improve treatment compliance and satisfaction with nursing, which is worthy of popularization.

OBJECTIVE To analyze the profile of the pathogens and their drug resistance isolated from children with lower respiratory tract infection in Wenzhou area from Jan 2004 to Dec 2006.METHODS Lower respiratory tract secretions were obtained from children with lower respiratory tract infection for bacterial culture.The K-B method was applied for the antibiotic susceptibility test.RESULTS Total 1605 strains were isolated.The isolating rates of Gram-positive cocci,Gram-negative bacilli and fungi were 24.9%,61.2% and 14.0%,respectively.60.5%,and 54.6% of the isolates of Escherichia coli and Klebsiella pneumoniae produced extended-spectrum beta-lactamases(ESBLs).The rate of Penicillin-resistant Streptococcus pnenmoniae(PRSPN)was 30.6%.20.5% isolates of Staphylococcus aureus were MRSA.All isolates of Enterobacteriaceae and Gram-positive cocci were susceptible to imipenem and vancomycin in vitro.CONCLUSIONS Gram-negative bacilli are still the primary pathogens resulting in lower respiratory tract infection in children.Fungi and muti-drug-resistant bacteria are on the rise trend.

Objective To analyze the prevalence and genetic characteristics of influenza A(H3N2) viruses in the city of Xiangyang in 2022-2023, and to provide a scientific basis for predicting the epidemic and mutation of influenza virus. Methods Throat swab specimens of the influenza like cases were collected from national influenza monitoring sentinel hospitals in Xiangyang every week. RNA was extracted from the specimens for influenza diagnosing using real-time RT-PCR．Viruses were isolated from H3N2 positive specimens, and HA and NA genes were amplified and sequenced．3D modeling analyses were conducted. Results The gene phylogenetic tree showed that the H3N2 isolates in 2022-2023 belonged to 3C.2a1b.2a1 and 3C.2a1b.2a2 branches, respectively. The A(H3N2) influenza virus strains all had amino acid point mutation sites on important antigenic determinants of HA protein. The epitope mutations of the 2022 A(H3N2) strain mainly occurred in regions B, C, and D. The epitope mutations of the A(H3N2) strain in 2023 mainly occurred in regions C and D. Different glycosylation sites of HA gene were found in 2022-2023 strains. No variation was found in key amino acid sites associated with neuraminidase inhibitor resistance. The difference of overall structure was not obvious in the three-dimensional simulation structure diagram. Conclusion The A(H3N2) influenza strains isolated in this study have shown antigenic drift, especially the mutation of HA, which may affect the protective effect of the vaccine on the local population and lead to influenza epidemic. The variations of HA and NA suggest that close attention should be paid to the epidemic and genetic variation of H3N2 subtype influenza virus, to provide a scientific basis for the selection of influenza virus vaccine strains and the prevention and control of influenza.

Objective To understand the exposure level of disinfection by-products (DBPs) in drinking water in Xiangyang City and to evaluate the health risks of the population, so as to provide reference for the safety risk control of drinking water. Methods Sampling and laboratory testing were conducted according to national standard methods. The risk assessment model provided by USEPA was used to evaluate the health risks. Results Trichloromethane (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM) and tribromomethane (TBM) were detected in drinking water in Xiangyang City. The contents of halogenated hydrocarbon DBPs in water disinfected with liquid chlorine were higher than those with chlorine dioxide. The contents of three DBPs were higher in wet season than those in dry season except TBM. The content of TCM in pipe network terminal water and secondary water supply disinfected with chlorine dioxide was higher than that in factory water. The carcinogenic risk of DBPs in drinking water disinfected with liquid chlorine was 4.33×10^-5, and the non-carcinogenic risk was 0.114. The carcinogenic risk of DBPs in drinking water disinfected with chlorine dioxide was 1.24×10^-6, and the non-carcinogenic risk was 3.15×10^-3. Conclusion The health risk of DBPs in drinking water in Xiangyang City is acceptable, but TCM produced by liquid chlorine disinfection should be paid more attention. It is recommended that chlorine dioxide disinfection be used to reduce the health risks of halogenated hydrocarbon DBPs.

Objective:To detect the effect of Celecoxib on the proliferation and apoptosis of human nasopha-ryngeal carcinoma cell line CNE-2. Method:The growth inhibition rate of CNE-2 by Celecoxib was evaluated with MTT method. Apoptosis related morphology changes were observed with transmission electron microscopy (TEM). The cell cycle and apoptosis were measured with flow cytometric method (FCM). Apoptotic index ( AI) was counted by the TDT-mediated dUTP-biotin nick end-labeling (TUNED assay. Result: The growth of CNE-2 cell was inhibited by celecoxib in a dose-and time-dependent manner. Apoptosis with nuclear chromatin condensa-tion, cell shrinkage, periplast loss and the formation of apoptotic bodies was observed with TEM. Apoptotic rates of CNE-2 cells treated with 80 and 100 μmol/L celecoxib were (10. 47±0. 18)% and (20. 17±0. 55)% respective-ly, significantly higher than those of the control group (1. 57±0. 27)% with FCM. The percentage of G_0/G_1 phase cells increased, whereas the S and G_2/M phases cells decreased in a dose-dependent manner after the treatment. TUNEL assay showed that the apoptosis ratio( AI) of CNE-2 treated with Celecoxib was higher than control group (P<0. 01). Conclusion:Celecoxib can inhibit the growth of human nasopharyngeal carcinoma cell line CNE-2 and induce the cell apoptosis, which may be related to blocking the cell cycle progress of CNE-2 cells.

Objective To investigate the value of ADC histogram analysis in the assessment of response to neoadjuvant chemotherapy (NACT) in patients with in locally advanced breast cancer (LABC). Methods Thirty?five female patients with invasive ductal carcinoma proved by pathology before NACT and treated with operation after NACT were retrospectively analyzed. All patients were received MR examination (including non?enhanced MRI, enhanced?MRI, and DWI) breast before NACT. After neoadjuvant chemotherapy, 19 of 35 patients were categorized as responders and 16 were categorized as non?responders according response evaluation criteria in solid tumors criteria. Per?patient weighted ADC histograms were generated. Mean ADC, mode ADC, maximum ADC, minimum ADC, median ADC, skewness, and kurtosis were analyzed by using t test between responders and non responders groups. ROC curves were constructed to determine the optimum threshold for each histogram parameter to differentiate non?responders and responders in breast cancers. The optimal threshold values, determined by maximal Youden index were selected when significant differences existed in two groups. Results Mean, minimum, skewness, and kurtosis of ADC between responders and non?responders group were(0.955 ± 0.135)× 10?3mm2/s,(0.535 ± 0.115)×10?3mm2/s,0.85±0.61, 2.93±0.17,and(1.103±0.233)×10?3 mm2/s,(0.650±0.104)×10?3mm2/s,-0.42± 0.17, 3.11 ± 0.25,respectively. Significant differences were found mean ADC, minimum ADC, skewness, and kurtosis (t=2.345, 3.096, 8.051 and 2.524,P<0.05), and there was no differences in mode, median, maximum between responders and non?responders(P>0.05).We set the optimal threshold criteria of mean ADC (0.956×10?3mm2/s), minimum ADC (0.580×10?3mm2/s), skewness (0.890), sensitivity, specificity of three parameters for predicting responders in LABC were 73.7%,62.5%, 78.9%,68.8%, and 63.2%,75.0%, respectively, and the areas under ROC curve of mean ADC, minimum ADC, skewness was 0.678, 0.770, and 0.890, respectively. Kurtosis of responders and non?responders did not get cutoff value for much more overlap. Conclusion ADC histogram analysis is valuable in predicting LABC in patients with NACT effect, the minimum and skewness of ADC is highest sensitivity, specificity, respectively.

Objective To investigate the value of diffusion weighted imaging (DWI)in identification of different molecular sub-types for breast cancer classifications.Methods All patients with breast cancer were divided into four subtypes groups by immuno-histochemistry results including Luminal A subtype,Luminal B subtype,HER2-over expressing (HER2-OE)subtype,and triple negative breast cancer (TNBC),respectively.The means of maximum,average,and minimum ADC of the lesions in all patients were recorded.The analysis of ANOVA and least significant difference test (LSD-t )were used for the statistical evaluation.Results There were significant differences in maximum ADC,average ADC,and minimum ADC among Luminal A subtype (n=21),Lu-minal B subtype (n=22),HER2-OE subtype (n=1 7)and TNBC subtype (n=12)groups (P =0.025,0.039 and 0.041,respec-tively).However,paired comparison in mean of maximum ADC,average ADC and minimum ADC by LSD-t multiple comparisons among Luminal A,Luminal B,HER2-OE and TNBC respectively were not significantly different.Conclusion DWI may be difficult to discriminate the molecular subtypes of breast cancer classification before surgery or biopsy.
