A retrospective study included 30 cataract cases (30 eyes) with history of vitrectomy. Phacoemulsifica-tion or small incision non-phacoemulsification was performed with vitreous irrigation of 23G TSV. Observe the visual acuities, intraoperative and postoperative complications. Posterior capsule rupture intraoperatively occurred in one patient with phacoemulsification. Three patients suffered intraocular hypotension postoperatively, including one with choroidal detachment, and the other two probably with leakage from incisions. However,the intraocular pressure rised to normal after treatment. Corneal edema and aqueous flare postoperatively occurred in four patients with hard nucleus cataract and three patients with diabetic retinopathy. There were no serious complications occurred in all patients, such as sclera collapse, nucleus sinking into vitreous chamber and bleeding in epichoroidal space. The visual acuities were improved after operation in twenty-eight patients.

Objective To explore a simplified method of coagulation test for the individuals with erythrocytosis. Methods The antico-agulants, blood volume and fixed blood collecting volume were adjusted by the formula: anticoagulants (mL)＝(100－HCT×100)× blood (mL)×0.001 85. A total of 124 blood samples for coagulation testing in which the calcium ( Ca2+) interval was designated and hematocrit (HCT) was more than 55% were tested with calibrated anticoagulants, adjusted blood volume and fixed blood collection vol-ume [anticoagulant(mL)/0.055 5]. The results of plasma prothrombin time (PT), international standardization ratio (INR) and acti-vated partial thromboplastin time (APTT) before and after adjustment were compared. The results of the samples from 3 groups after adjustment were also compared. The relationship of HCT with unadjusted PT and APTT were simultaneously observed. Results The unadjusted results of PT, INR and APTT were significantly higher than those after anticoagulants adjustment (27.52±16.37 vs 12.49± 1.35, 2.31±1.47 vs 0.99±0.11 and 50.09±13.32 vs 33.37±5.05) with statistically significant difference in paired comparison (P＜0.05). No statistical difference was found in the comparison of the results for PT, INR and APTT after adjustment within the 3 groups ( PT: 12.49±1.35 vs 12.84±1.54 vs 12.82±1.76, INR:0.99±0.11 vs 1.02±0.13 vs 1.02±0.15, APTT: 33.37±5.05 vs 33.49±5.09 vs 32.83±5.06) (P＞0.05). HCT values of the patients were positively correlated with unadjusted PT (r＝0.461, P＜0.05) and APTT (r＝0.571, P＜0.05). Conclusion The coagulation test of the individuals with erythrocytosis may use to adjust the blood volume and the fixed blood collection volume provided calcium concentration in reference interval.

Objective:To establish and apply the electronic further modified early warning score system (e-fMEWS), and explore its role in the condition evaluation and early warning of inpatients in non-critical units, so as to provide clinical nurses with an early and dynamic method to identify the potential deterioration risk of patients' condition.Methods:A retrospective analysis of 262 805 inpatients in multiple non-critical units of the Second Affiliated Hospital of Zhejiang University School of Medicine from January to December 2018 and January to December 2020 was performed. The patients who were hospitalized from January to December 2018 were used as the control group, and the responsible nurse used the traditional single evaluation index to start the emergency response system; the patients from January to December 2020 were used as the research group, and the emergency response system was started using e-fMEWS. The inclusion criteria were as follows: (1) hospitalization time ≥24 h; (2) patient ≥14 years old. Exclusion criteria were as follows: (1) patients had cardiopulmonary resuscitation before admission; (2) patients discontinued treatment or were transferred to another hospital during treatment; (3) patients received palliative care; (4) patients were admitted to non-critical wards in grade I of emergency pre-examination and triage. The activation of the rapid response team (RRT), the activation of the cardiorespiratory arrest team, the incidence of cardiac and respiratory arrest, the number of cases of invasive mechanical ventilation, the number of cases admitted to the intensive care unit, the length of hospital stay and the prognosis were compared. Statistical software SPSS 22.0 was used for data analysis.Results:Under the e-fMEWS assessment, compared with the control group, the rate of initiation of the research group decreased by 0.03%. For patients who initiated RRT, the average length of hospital stay was shortened, and the number of in-hospital respiratory cardiac arrest decreased (12.2% vs. 13.2%) and the number of cases transferred to the intensive care unit was less (42.8% vs. 50.6%), the rate of improvement and recovary increased (58.4% vs. 56.1%).Conclusions:The application of e-fMEWS can help clinical nurses to quickly and accurately identify the potential risk of deterioration of the patient's condition. Through early identification of potentially critically ill patients in non-critical units, early intervention and timely treatment can avoid adverse events and improve the patient prognosis.

Objective: To understand the factors affecting the compliance of blood glucose monitoring in patients with type 2 diabetes in rural areas, and to provide evidence for improving the compliance of patients with blood glucose monitoring. Methods: A method of phenomenological study in qualitative research was conducted to conduct deep semi-structured interviews on 43 patients with poor blood glucose compliance in type 2 diabetes in rural areas, and to analyze the collected data. Results: Extracted five themes: bad experience affected compliance; lack of knowledge about blood glucose monitoring; economic and time was not sufficient; "long-term illness into a good doctor" overconfidence; social support uncertainty. Conclusions The status of blood glucose monitoring in rural type 2 diabetes patients is not optimistic. In order to improve the compliance of patients with blood glucose monitoring, nursing workers should pay attention to the mastery of blood glucose monitoring knowledge in rural type 2 diabetes patients, improve blood glucose monitoring methods and techniques, and give full play to the role of family doctors. Efforts to improve patient blood glucose monitoring compliance.
