Objective To determine and compare the minimum local analgesic concentration(MLAC) of ropivacaine and bupivacaine in continuous block of axillary brachial plexus for postoperative active mobilization of flexor tendon. Methods Seventy ASA Ⅰ or Ⅱ patients undergoing relaxation of flexor tendon were randomly allocated into 2 groups (n = 35 each): ropivacaine group (group R) and bupivacaine group (group B). A catheter was inserted into axillary sheath using B. Braun stimulating intraducer, 24-48 h after operation. 30 min before functional exercise 20 ml of ropivacaine or bupivacaine was injected through catheter. The minimum local analgesic concentration of both local anesthetics was determined by up-and-down sequential test. The first concentration of both local anesthetics was 0.1%. The next concentration of local anesthetic was determined by response of the previous patient. The analgesia efficacy was assessed using 100 mm VAS score (0 = no pain, 100 mm = worst possible pain) . Increase/decrease in VAS by 10 mm was defined as effective. An effective result resulted in increase/decrease by 0.01% in the next patient. The motor block was also recorded.Results The two groups were comparable with regard to age, sex, body weight and baseline VAS score. The MLAC of ropivacaine was 0.133% [95% confidence interval (CI), 0.128%-0.138%] and MLAC of bupivacaine was0.121% (95%CI, 0.116%-0.126%). The analgesic potency of ropivacaine was 10% less than that of bupivacaine. The potency ratio of ropivacaine to bupivacaine was 0.91. The degree of motor block is higher with bupivacaine than with ropivacaine. Conclusion The results of our study show that the analgesic potency of ropivacaine is 10% less than that of bupivacaine. The degree of motor block is higher with bupivacaine than with ropivacaine.

Objective To explore current status of health-related productivity loss and its risk factors among nurses.Methods Stanford presenteeism scale (SPS-6) and self-designed questionnaire were used to investigate current status of health-related productivity loss and its risk factors among 1122 nurses working in a tertiary hospital in Changchun city.Results Compared with hired nurses,age and work seniority of permanent nurses were significantly higher(Z =-19.49,-19.28 ;P ＜0.05).The average score of SPS-6 of all the participants was 20.05 ± 4.37.The score of SPS-6 of married nurses was significantly lower than other nurses (Z =-3.52,P ＜ 0.05) ; and the score of SPS-6 of nurses less than 30 years old was significantly higher than those above 30 years old (Z =-2.49,P ＜ 0.05).There were no significant differences between the SPS-6 score of education degree and department.(Z =-1.37,x2 =0.58 ; P ＞0.05).The result of GLM showed that employment status and work seniority were independent risk factors of health-related productivity loss among nurses.The scores of SPS-6 of permanent nurses was significantly lower than hired nursed (x2 =4.48,P ＜ 0.05),and those who had worked for less than 3 years showed significantly higher score of SPS-6 than those who had worked longer (x2 =12.89,P ＜ 0.05).Conclusions Health-related productivity loss do exist among nurses.Improving health management may help to reduce this loss of productivity.

DNA damage repair gene mutations are prevalent in advanced prostate cancer. Among these, mutations in homologous recombination repair genes could impair the ability of cell to restore the DNA double-strand break, which can be exploited by Poly-ADP-ribose polymerase (PARP) inhibitors through synthetic lethality and result in cell death. The phase Ⅲ study " PROfound" showed that the PAPR inhibitor Olaparib could significantly improve the survival of patients with homologous recombination repair gene mutations compared with novel hormone agents, starting the era of targeted, precise and individualized treatment based on genetic profile detection for prostate cancer treatment.

Objective To summarize and analyze the epidemiological and clinical characteristics of COVID-19 Omicron variant cases in makeshift hospital, and the influence of age, sex and vaccination status on the disease duration, so as to provide reference for the prevention and control of the COVID-19 epidemic. Methods The epidemiological and clinical characteristics of COVID-19 cases admitted to makeshift hospital of National Convention and Exhibition Center (Shanghai) from April 9 to May 31, 2022 were retrospectively described and analyzed, and further cohort analysis was conducted to determine the influence of age, sex and vaccination status on the disease duration of COVID-19 cases in the author's branch hospital. Results Among the 174 466 COVID-19 cases in makeshift hospital, most of them were male, accounting for 59.38%. The infected cases were mainly young and middle-aged people aged 18-59 years old, accounting for 83.50%, followed by 12.30% of the elderly group over 60 years old; the average hospital stay was 7.40 days; the proportion of patients with fever was less than 27.79%; 15.37% (26 817/174 466) of the patients complicated with underlying diseases, and the top three were hypertension, diabetes and coronary heart disease. The proportion of people who received COVID-19 vaccine accounted for 79.56% (13 799/17 956), of which the highest proportion of three doses was 44.09%. The disease duration of 17 956 COVID-19 cases in the author's branch of makeshift hospital was 10.18 (7.34, 13.05) days. The disease duration in the elderly group was the longest with 11.34 (8.35, 14.37) days, followed by 11.17 (9.07, 14.33) days in the preschool group, 10.37 (8.14, 13.34)· days in the middle-aged group, 10.07 (7.37, 12.37) days in the school-age group, and 9.34 (7.05, 12.16) days in the young group. There was significant difference in the overall distribution of disease duration among the five groups (H=550.479 P<0.01). The disease duration in each age group basically showed a V-shaped distribution. The disease duration was 10.27 (7.34, 12.57) days in males and 10.10 (7.25, 13.09) days in females, and there was no significant difference (Z=-1.505 P>0.05). The disease duration of vaccinated patients was 10.24 (7.35, 13.05) days, and that of unvaccinated patients was 9.47 (7.09, 12.47) days. There was significant difference between the two groups (Z=-4.338 P<0.01). Conclusions COVID-19 Omicron variant cases have a high proportion of males, mainly young and middle-aged, and the proportion of fever patients is less than 30%. The disease duration is significantly lower than that of the original strain in Wuhan, and shows "V" distribution with each age group. Sex had no effect on the disease duration. COVID-19 vaccination did not have a clinical effect on the disease duration.
