Objective To study the new nursing method of patients complicated with urinary fistula after gynecological malignancy operation. Methods Nursing measures were provided with sufficient nutritional support and prevention of urinary tract infection by perineal nursing, vaginal plugging by OB sliver,and using endovaginal catheter to 23 patients complicated with urinary fistula after gynecological malignancy operation. Results 18 patients recovered by treatment and nursing, 4 mild cases cured after discharge from hospital and 1 patient died of MODS and multiple metastasis. Conclusions Vaginal plugging by OB sliver, perineal nursing and sufficient nutritional support have positive effect for patients complicated with urinary fistula after gynecological malignancy operation.

Objective To observe the clinical efficacy of acupuncture plus contralateral needling in treating post-stoke myodystonia. Method Totally 120 patients with post-stroke myodystonia were randomized into group A, B, C and D, 30 in each group. Group A was intervened by yin-reducing and yang-tonifying needling method plus contralateral needling; group B was by ordinary acupuncture plus contralateral needling, group C was by yin-reducing and yang-tonifying needling alone, while group D by ordinary acupuncture. Clinical Spasticity Index (CSI) was observed before and after intervention. Result After treatment, the CSI scores (tendon reflex, muscle tension, episodic spasm scores and total score) were significantly changed in the four groups (P<0.01, P<0.05). The tendon reflex score, muscle tension score and total score in group A were significantly different from that in the other three groups after intervention (P<0.01,P<0.05). There was a significant difference in comparing the episodic spasm score between group A and D after intervention (P<0.01). There were significant differences in comparing the tendon reflex score, muscle tension score and total score between group B and D after intervention (P<0.05). The total score in group C was markedly different from that in group D after intervention (P<0.05). Conclusion Yin-reducing and yang-tonifying needling method plus contralateral needling is an effective method in treating post-stroke myodystonia.

Objective To investigate the drug use in the pediatric outpatient department of Ningbo Women & Children′s Hospital ,summarize the existing problems and analyze the causes in order to ensure the safety and effectiveness of the drug use .Methods A total of 9 000 prescriptions were randomly sampled from January to December 2015 for the statistical analysis of the drug use ,the amount of money spent on the drugs and the number of irrational prescriptions at the pediatric outpatient department in our hospital .Results Based on the amount of money spent ,the four most commonly used drugs were Chinese traditional drugs ,anti-infective ,respiratory and digestive system drugs .A total of 122 electronic prescriptions were considered as irrational drug use (1 .34% ) which include improper administration method ,wrong dosage or indications ,computer input errors ,etc .Conclusion Overall ,the drug use is appropriate at the pediatric outpatient department in our hospital .The Chinese traditional drugs are the most commonly used medications .However ,clinical doctors and pharmacists still need the comprehen-sive trainings to promote the rational drug use ,which could reduce unnecessary disputes between patients and doctors .

Objective To investigate the teaching effects of flipped class model on the Surgery Intensive Care Unit (SICU) nurses' ability of autonomic learning. Methods From July to December 2015, a total of 38 nurses who worked in SICU of Zhejiang Cancer Hospital were selected as the research objects by convenience sampling method. The nurses were trained in postoperative pain management knowledge by flipped class model, and were evaluated before and after the training by rating scale of self-directed learning competence for nurses. Results The total score of rating scale of self-directed learning competence for nurses, self motivation belief, task analysis, self monitoring and regulation, self evaluation were (128.26±18.69), (54.50±7.65), (22.05±3.66), (37.57±5.82) and (14.13±2.67) after the training, which all improved than (108.89±15.71), (47.18±6.61), (18.03±3.33), (31.37±5.24) and (12.32±2.14) respectively before training. The differences were statistically significant (t=-4.889, -4.460, -5.013, -4.883, -3.266; P<0.05). Conclusions Flipped class teaching model improves nurses' autonomous learning ability comprehensively and provide a new teaching mode for nurses' training.

The global COVID-19 coronavirus pandemic has infected over 109 million people, leading to over 2 million deaths up to date and still lacking of effective drugs for patient treatment. Here, we screened about 1.8 million small molecules against the main protease (M^pro) and papain like protease (PL^pro), two major proteases in severe acute respiratory syndrome-coronavirus 2 genome, and identified 1851M^pro inhibitors and 205 PL^pro inhibitors with low nmol/l activity of the best hits. Among these inhibitors, eight small molecules showed dual inhibition effects on both M^pro and PL^pro, exhibiting potential as better candidates for COVID-19 treatment. The best inhibitors of each protease were tested in antiviral assay, with over 40% of M^pro inhibitors and over 20% of PL^pro inhibitors showing high potency in viral inhibition with low cytotoxicity. The X-ray crystal structure of SARS-CoV-2 M^pro in complex with its potent inhibitor 4a was determined at 1.8 Å resolution. Together with docking assays, our results provide a comprehensive resource for future research on anti-SARS-CoV-2 drug development.
