目的 評價手衛生健康教育對重癥監護病房（ICU）患者家屬手衛生依從性的影響。 方法 選取2012年3月－5月ICU患者家屬558人，對其進行手衛生健康教育。將健康教育前的1個月定義為第1階段(基線調查階段），健康教育當月定義為第2階段，健康教育結束后的第1個月定義為第3階段。對ICU患者家屬開展手衛生健康教育，第1和第3階段均采用張貼展板和宣教圖片，床旁準備速干手消毒液；第2階段在此基礎上，每周示范六步洗手法3次，由責任護士督促并指導家屬使用速干手消毒液進行手衛生。觀察3個階段患者家屬手衛生依從性變化情況。 結果 在對“接觸患者前”、“接觸患者后”和“接觸患者周圍環境后”3個手衛生時機的依從率比較中，第2階段明顯高于第1階段（P＜0.01）；第3階段較第2階段有明顯下降（P＜0.01）；在3個階段中，使用速干手消毒液進行手衛生的人數均高于使用洗手液的人數。 結論 手衛生健康教育普及了手衛生相關知識，提高了ICU患者家屬對手衛生的依從性。
ObjectiveTo investigate the diagnostic value and the best criteria of multiplanar reconstruction (MPR) of spiral CT in recurrent laryngeal nerve lymph node metastasis.MethodsWe performed multiplanar reconstruction of the spiral CT data of 138 esophageal carcinoma patients admitted to our hospital between December 2016 and June 2019, including 113 males and 25 females with an average age of 47-85 (63.03±15.58) years. The short and long diameters of recurrent laryngeal nerve lymph nodes were measured respectively, and then ratio of short to long diameter was calculated. The three parameters were contrasted with the pathological results and the receiver operating characteristic (ROC) curves for the parameters were drawn.ResultsOf the 138 patients, 291 left recurrent laryngeal nerve lymph nodes were dissected with an average number of 0-14 (2.11±0.41) per patient and the metastasis rate was 16.70%; while 436 right ones were dissected with the average number of 0-17 (3.16±0.45) per patient and the metastasis rate was 21.00%. The total metastasis rate was 29.70%. In the diagnosis of lymph node metastasis, the areas under ROC curve for short and long diameters as well as the ratio of short to long diameter of left recurrent laryngeal nerve lymph nodes were 0.808, 0.779, 0.621, respectively, while those for the right ones were 0.865, 0.807, 0.637, respectively.ConclusionThe metastasis rate of recurrent laryngeal nerve lymph nodes is high and the short diameter has a higher diagnostic value for recurrent laryngeal nerve lymph node metastasis.
Objective To know about the baseline and quality of clinical prophylaxis and treatment study on communicable diseases in China, by identifying and assessing the clinical studies published in Chinese Journal of Infectious Diseases for 18 years. Method Handsearching page by page to identify and register the clinical studies from the journal, the definition of randomized controlled trial (RCT) and controlled clinical trial (CCT) strictly according to the Cochrane Collaboration Handbook (1997). Results There were totally 214 clinical studies during the 18 years, including 67 RCTs, 67 CCTs and 80 Non-CCTs. The average sample size of the RCTs was 103.0±70.2 (range from 17 to 296). Counted by every 5 years period (3 years period from 1998 to 2000), the proportion of RCTs in clinical studies was increasing steadily. The proportion were 22.9% from 1983 to 1987 (11/48), 29.2% from 1988 to 1992 (14/48), 41.9% from 1993 to 1997 (26/62), 28.6% from 1998 to 2000 (16/56) respectively. The main diseases studied in 214 clinical studies include: virus hepatitis (65 studies), hemorrhagic fever with renal syndrome (19 studies), typhoid fever (11 studies), bacterial infection (13 studies), bacillary dysentery (5 studies), epidemic encephalitis B (3 studies) and parasitosis (9 studies). Conclusion RCT study design should be applied as much as possible. The quality of clinical studies on communicable diseases in China remains to be improved. Multi-center and large-scale collaborative study is worthy to advocate.
Objective To understand the sexual behavior statu of married migrant workers in Chongqing, so as to provide the government with foundation for formulating related social strategies. Methods A multi-stage stratified cluster random sampling method was applied to select respondents, and the face-to-face interview was performed to investigate by trained investigators. The date was analyzed by using SAS9.0 software. Results A total of 377 married migrant workers were investigated. Among them, 226 (59.95%) lived with their spouses, of whom 13.72% had extramarital sexual behaviors, with 48.39% commercial sexual behaviors; the other 151 (40.05%) didn’t live with their spouses, of whom 49.25% had no normal sexual life for at least three months and 28.48% had extramarital sexual behaviors, with 60.47% commercial sexual behaviors. 66.41% of male migrant workers and 46.28% of female migrant workers had sexual depression, and different genders between the migrant workers were statistically significant (Plt;0.05). Conclusion There is sexual depression among married migrant workers. The related measures should be taken according to the status of their sexual behaviors, so as to improve their status of sexual depression.
The QUADAS-2, QUIPS, and PROBAST tools are not specific for prognostic accuracy studies and the use of these tools to assess the risk of bias in prognostic accuracy studies is prone to bias. Therefore, QUAPAS, a risk of bias assessment tool for prognostic accuracy studies, has recently been developed. The tool combines QUADAS-2, QUIPS, and PROBAST, and consists of 5 domains, 18 signaling questions, 5 risk of bias questions, and 4 applicability questions. This paper will introduce the content and usage of QUAPAS to provide inspiration and references for domestic researchers.
This study aims to investigate the protective effect of resveratrol against liver injury in hindlimb unloading rats. Thirty 2-month-old male SD rats were randomly divided into normal group (Control), hindlimb unloading model group (Model), and hindlimb unloading+resveratrol administration group (Model+Res). The Model + Res group was injected intraperitoneally with 30 mg/kg of resveratrol, and the Control and Model groups were injected intraperitoneally with an equal volume of 0.9% NaCl. Liver tissues were collected after 28 days and analyzed for oxidative stress, inflammatory factors, energy metabolism indices, Na+-K+-ATPase and Ca2+-Mg2+-ATPase activity, and morphological changes were observed by hematoxylin-eosin staining. The protein expression levels of Bax, Bcl-2, p-PI3K, PI3K, p-AKT, and AKT were detected by Western blotting. Compared with the Control group, hepatocytes in the Model group showed swelling, abnormal morphology, nuclear consolidation, and cell membrane disruption. Oxidative stress, inflammatory factor levels, hepatic glycogen accumulation, and energy metabolism were increased in the liver tissues of the Model group, while resveratrol treatment significantly reversed these changes. The results of Western blotting showed that resveratrol significantly reduced the expression of Bax and increased the expression levels of Bcl-2, and the proteins of p-PI3K/PI3K and p-AKT/AKT expression levels. It is suggested that 28 days of hindlimb unloading treatment could lead to liver tissue injury in rats, which is manifested as oxidative stress, inflammatory response, energy metabolism disorder and increased apoptosis level, and resveratrol has a certain mitigating effect on this.
The use of clinical predictive modeling to guide clinical decision-making and thus provide accurate diagnosis and treatment services for patients has become a clinical consensus and trend. However, the models available for clinical use are more limited due to unstandardised research methods and poor quality of evidence. This paper introduces the development process of clinical prediction models from six aspects, data collection, model development, performance evaluation, model validation, model presentation and model updating, as well as the clinical prediction model research report statement and risk of bias assessment tools in order to provide methodological references for domestic researchers.
