Objective We summarized the nursing care experience of spinal muscular atrophy complicated with pneumonia.Methods The measures of nursing care to the 9 children patients were comprised of preventing sputum blockage; preventing suffocating due to milk choking; paying special attention to the time being when the sputum blockage and milk choking occurred; early detection of paralysis of respiratory muscle; and training nursing skills to the families,and so on.Results All 9 children patients were cured and discharged from hospital.Conclusions The measure of targeting nursing intervention to the children with infantile spinal muscular atrophy and pneumonia could improve therapeutic effect and reduce mortality rate.

Objective:To explore the problems influencing doctor-patient harmony, and provide basis for im-proving the doctor-patient relationship. Method: China Knowledge Resource Integrated Database ( CNKI) and other databases were retrieved, keywords retrieved"doctor-patient harmony or doctor-patient relationship or doc-tor-patient dispute or doctor-patient conflict or doctor-patient communication or doctor-patient trust", ab-stracts retrieved"problem or challenge or obstacle or crisis" and the retrieval period was set"2009-2016", form-ing a collection of literature. Then boundary analysis method was used to determine whether the problem was satu-rated or not, and finally "macro model of health system" was used to classify and summarize the problems. Re-sults:The problems influencing the doctor-patient harmony can be summarized into 29 categories, covering 5 ma-jor aspects, which were resources, organization, process, results and external environment problems respectively. Conclusion:The various internal problems influencing the doctor-patient harmony interplay and mutually influ-ence, and also interconnect with external macro environment.

Objective:To investigate the microbiota distribution and drug resistance in gravidas with suspected infection to provide a reference for the treatment of maternal infectious diseases.Methods:This retrospective study analyzed the distribution and in vitro antimicrobial susceptibility of microorganisms isolated from obstetric patients in Beijing Obstetrics and Gynecology Hospital Affiliated to Capital Medical University (Beijing Maternal and Child Health Care Hospital) from January 1, 2016. to December 31, 2019. Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was used to identify pathogenic microorganisms. The susceptibility of isolated pathogenic bacteria to common antimicrobial agents was detected using bioMerieux VITEK-2 (France). Descriptive statistical methods was used. Results:A total of 4 086 strains were isolated from 3 781 samples of 3 225 gravidas and 44.17% (1 670) of the strains were from secretion specimens, including 767 cervical, 423 vulvovaginal, 318 perineum wound and 117 uterine secretion specimens. The most common bacterium was Escherichia coli (1 728, 42.29%), followed by Saccharomyces (901, 22.05%), Streptococcus (429, 10.50%), Enterococcus (377, 9.23%), and Staphylococcus (300, 7.34%). The proportion of Enterococcus among all the positive bacteria increased during the study period with its ranking rising from the 5th in 2016 to the 3rd in 2019, while the ranking of the proportion of Staphylococcus fell from the 4th in 2016 to the 5th in 2019. More than 90% of Escherichia coli were sensitive to carbapenems, piperacillin/tazobactam, amikacin, nitrofurantoin and ceftazidime, but only 35% or less to ampicillin and cefazolin. More than 98% of Candida strains were sensitive to amphotericin, but less than 56% to itraconazole. From 2016 to 2019, the sensitivity of Escherichia coli to cefuroxime sodium and ceftriaxone remained around 65%. The sensitive rate of Candida albicans to voriconazole and fluconazole gradually decreased from about 90% to 56%. The most common Enterococcus was Enterococcus faecalis and its susceptibility to vancomycin, ampicillin, penicillin, linezolid, nitrofurantoin and levofloxacin were all over 90%. Conclusions:Escherichia coli is the most common pathogenic microorganism in gravidas with suspected clinical infection and its susceptibility to cefuroxime sodium and ceftriaxone is stable. Candida albicans shows a gradually decreased susceptibility to voriconazole and fluconazole, which needs close attention. The proportion of Enterococcus in all pathogenic bacteria increases significantly over time, while that of Staphylococcus decreases.

Objective:To analyze the vaginal microecological status of vaginitis population and non-vaginitis population of gynecological female outpatients.Methods:A total of 30 265 women who visited the gynecological outpatient clinic of Beijing Obstetrics and Gynecology Hospital from December 2018 to December 2020 completed vaginal microecological examination. After removing the follow-up patients, 23 181 women were divided into group with symptoms and signs of vaginitis (6 697 cases) and group without symptoms and signs of vaginitis (16 484 cases), according to whether the women with symptoms and signs of vaginitis or not. And the vaginal microecological status of the two groups was compared and analyzed.Results:(1) The total detection rate of vaginitis in the initial women was 34.87% (8 083/23 181), of which 46.10% (3 087/6 697) in group with symptoms and signs of vaginitis and 30.31% (4 996/16 484) in group without symptoms and signs of vaginitis, nearly 1/3 of the gynecological outpatients without signs and symptoms of vaginitis had vaginitis. (2) Among the types of simple vaginitis, vulvovaginal candidiasis (VVC) was the most frequent in group with symptoms and signs of vaginitis (16.01%, 1 072/6 697), followed by aerobic vaginitis (AV; 12.83%, 859/6 697), with significant differences compared with group without symptoms and signs of vaginitis (all P<0.001). There were no statistical differences between the two groups of bacterial vaginosis (BV) and trichomonal vaginitis (TV), indicating that BV and TV were more likely to be neglected (all P>0.05). (3) The proportion of various combinations of vaginitis among 2 632 cases of mixed vaginitis were, in descending order: BV+AV, VVC+AV, BV+AV+VVC, AV+TV, AV+TV+BV, BV+VVC. (4) Microecological analysis of 15 098 cases diagnosed with non-vaginitis had normal flora (including those with normal flora and those with normal flora but decreased function) in 14 013 cases (92.81%, 14 013/15 098), abnormal flora in 429 cases (2.84%, 429/15 098) and the BV intermediate in 656 cases (4.34%, 656/15 098); this indicated that the vast majority of the microecological tests were normal in the vaginal microbiota of those without vaginitis. Conclusions:Microecological examination could diagnose multiple pathogenic infections at once, and is especially important as a guide for the definitive diagnosis of mixed vaginitis and vaginitis with atypical clinical symptoms. Vaginal infections such as BV and TV that are easily overlooked should be concerned.

Objective: To examine the expression of ATAD2 in different liver lesions and its clinical significance. Methods: ATAD2 expression in 60 hepatocellular carcinoma (HCC) surgical specimens (49 of which have concurrent liver cirrhosis), 43 HCC biopsy specimens, 2 high-grade liver dysplastic nodule specimens, 3 low-grade liver dysplastic nodule specimens, 50 liver cirrhosis tissue samples, and 20 normal liver tissue samples were measured using immunohistochemistry. The F-test, q-test, t-test, and chi-square test were used for statistical analysis of data. Results: ATAD2 was expressed in 56 HCC surgical specimens (93.33%), 35 HCC biopsy specimens (81.40%), and 2 high-grade liver dysplastic nodule specimens (2/2), but not in the low-grade liver dysplastic nodule, liver cirrhosis tissue, and normal liver tissue samples. The mean expression of ATAD2 was significantly higher in HCC tissues than in high-grade and low-grade liver dysplastic nodule tissues, liver cirrhosis tissue, and normal liver tissue (F = 22.96, q = 3.138, 3.972, 12.272, and 9.101, respectively, all P < 0.01). There were no significant differences in the mean expression and positive expression rate of ATAD2 between HCC surgical and biopsy specimens (t = 1.40, P > 0.05; χ² = 3.47, P >0.05). Of the 35 HCC biopsy specimens that expressed ATAD2, the mean ATAD2 expression was ≥1% in 35 specimens (100%), ≥3% in 27 specimens (77.14%), and ≥5 % in 23 specimens (65.71%). In addition, among the pathological grade I-II HCC biopsy specimens, the mean ATAD2 expression was ≥1% in 28 specimens (100%), ≥3% in 22 specimens (62.86%), and ≥5% in 19 specimens (54.29%). Moreover, ATAD2 expression in HCC was associated with serum alpha-fetoprotein level, presence of hepatitis B virus surface antigen (HBsAg), and presence of concurrent liver cirrhosis (t = 2.09, 2.30, and 2.18, respectively, all P < 0.05). Conclusion ATAD2 may play an important role in HCC tumorigenesis, and may be involved in malignant transformation of cells. ATAD2 expression can be a valuable marker for differentiating the nature of lesions in liver biopsy tissues during clinical practice.
