Chinese Journal of Hospital Administration 2017;33(1):54-56
Objective To investigate the direct economic loss of nosocomial infection at a tertiary hospital, so as to provide data support for the improvement of hospital infection control. Methods Inpatients discharged in 2013-2015 period were divided into two groups at a 1:1 pairing ratio, having those suffering from nosocomial infection in only one occasion as the infection group, and those without as the non-infection group. The two groups were compared of their differences in days of stay and hospitalization expenses. Results The days of stay of the infection group were significantly longer than the non-infection group, averaging 6 days longer in terms of the median. Compared with the non-infection group, the total hospitalization cost and the differences with sub-categories other than the treatment cost were of significance. The costs over the non-infection group were mostly contributed by drugs, accounting for 50. 39%, while 23. 50% of which were spent on antibiotics. The additional antibiotics costs were mainly incurred by respiratory tract infections during hospitalization, as the costs of antimicrobial agents for the infection group were 27. 34 times that of the non-infection group. The second contributor was surgical site infection, with the cost of antibiotics 7. 63 times that of the non-infection group. Conclusions Hospital infections prolong the days of stay, increase direct economic loss, especially increase the cost of antibiotics. Prevention and control of respiratory system and surgical site infection can effectively reduce the direct economic loss of hospital infection.

Objective To explore the value of placental alpha-microglobulin-1 in vagina liquid to diagnose premature rupture of membranes. Methods A prospective observational study to initial evaluation included both the standard clinical evaluation for rupture of membranes and placental alpha-microglobulin-1 immunoassay. Rupture of membranes was diagnosed if fluid was seen leaking from the cervical os or if two of the following three conditions were present: pooling of fluid, positive nitrazine test, or feming. Rupture of membranes was diagnosed definitively on review of the medical records after delivery. Results Placental alpha-microglobulin-1 immunoassay confirmed rupture of membranes at initial presentation with a sensitivity of 100% (89/89), specificity of 91% (10/11), positive predictive value of 99% (89/90), and negative predictive value of 100% (10/10),false positive rate of 9% (1/11). Placental alpha-nricroglobulin-1 immunoassay was better than the conventional clinical assessment in confirming the diagnosis of rupture ofmembranes (P<0.01). Conclusion Measurement of placental alpha-microglobulin-1 in cervicovaginal secretions is superior to conventional clinical assessment in the diagnosis of rupture of membranes.

Background and purpose: The Writ cell-signaling pathway is the key cellular developmental pathway. Dysregulation of this pathway has been implicated in the initiation and progression of cancer. Adenomatous polyposis coli (APC) is an important tumor suppressor gene of the Writ signaling pathway. The methylation of APC promoter and the accompanying loss of the APC transcript have been shown to occur in a significant proportion of cancers. However, there are few reports on the relationship between cervical cancer and methylation of APC. This study was aimed to investigate the promoter methylation status of the APC genes in cervical cancer and its correlation between clinicopathologic characteristics and the infection of high-risk HPV DNA. Methods: Promoter methylation was evaluated using a MSP (methylation-specific polymerase chain reaction) in 95 cervical cancer tissue specimens and 20 normal controls. The relationship between clinicopathologic parameters and the methylation status was evaluated. Results: The frequencies of promoter methylation of APC in cervical cancer were 56.8%. Cervical cancer had significant higher methylation frequencies than that of the controls (10%, P<0.01). The result showed that the methylation analysis of APC promoter and high-risk HPV DNA testing had good consistency (Kappa=0.348, P<0.001). The promoter methylation of APC was significantly higher in adenocarcinoma (AC) than in squamous cell carcinoma (SCC) (74.1% vs 50.0%, respectively, P<0.05). The larger tumor size, positive lymph node metastasis and positive HPV DNA exhibited an increased promoter methylation frequency for APC (P<0.05). There were no significant associations between the methylation frequencies for APC gene to age, invasion depth, FIGO stage and histological grade. Conclusion: Our results suggested that the promoter methyiation of APC and high-risk HPV DNA testing had good consistency. APC gene promoter methylation was a frequent epigenetic event in cervical carcinoma and had a significant correlation with cancer pathological types.

By using immunohistochemistry LSAB method and imaging analysis technique, the expression of α1-antitrypsinase (α1-AT) in 41 cases of bronchioalveolar carcinoma (BAC) was quantitatively detected to explore the relationship between αl-AT expression in BAC tissues and clinical pathology. The results showed that the total positive rate for αl-AT expression was 85.4%. The positive rate for αl-AT expression in alveolar BAC was 100%, with the immunity reactive staining intensity being significantly higher than in papillary BAC, mucinous BAC or sclerosing BAC (P<0.05). The positive rate in papillary BAC was 93.3%, with the intensity higher mucinous BAC or sclerosing BAC (P<0.01); The positive rate in both mucinous BAC and sclerosing BAC was 66.7% (P>0.05); The expression intensity in lymph node metastatic group was obviously lower than that in the group without metastasis (P<0.01); The patients with mucinous BAC were diagnosed at a younger age than those with other histologic types of BAC (P<0.05). It was suggested that BAC cells could also produce αl-AT. Detection of α1-AT could be used as a new method to diagnose BAC and might play a role in assessing BAC metastasis.
