Objective. This study is aimed at analyzing the effects of individualized nursing based on the zero-defect theory on perioperative patients undergoing laparoscopic cholecystectomy. Methods. 174 patients who underwent laparoscopic cholecystectomy from 1st November 2019 to 30th November 2020 were enrolled as the research subjects and randomly divided into control and observation groups. The patients in the control group received conventional perioperative nursing care, and the patients in the observation group were treated with individualized nursing based on the zero-defect theory. Results. The heart rate, diastolic blood pressure, and systolic blood pressure level of patients in two groups after nursing decreased significantly, and the reduction in the observation group was more significant than that in the control group. The depression and anxiety scores of the two groups after nursing were decreased, and the decrease in the observation group was significantly greater than that in the control group. The time to first postoperative exhaust, return to normal intake, out-of-bed activity, and hospital stay in the observation group was less than that in the control group. The incidence of postoperative complications in the observation group was substantially lower than that in the control group. The satisfaction degree of nursing care in the observation group was significantly higher than that in the control group. Conclusion. Individualized nursing care based on zero-defect theory can effectively reduce the perioperative psychological stress response of patients with laparoscopic cholecystectomy. It helps to improve the negative emotions of depression and anxiety, promotes the recovery of disease, reduces postoperative complications, and improves nursing satisfaction, which is worthy of clinical promotion.

Background H7N9 human cases were first detected in mainland China in March 2013. Circulation of this virus has continued each year shifting to typical winter months. We compared the clinical and epidemiologic characteristics for the first three waves of virus circulation. Methods The first wave was defined as reported cases with onset dates between March 31-September 30, 2013, the second wave was defined as October 1, 2013-September 30, 2014 and the third wave was defined as October 1, 2014-September 30, 2015. We used simple descriptive statistics to compare characteristics of the three distinct waves of virus circulation. Results In mainland China, 134 cases, 306 cases and 219 cases were detected and reported in first three waves, respectively. The median age of cases was statistically significantly older in the first wave (61 years vs. 56 years, 56 years, p
