OBJECTIVE To control the spread of multi-drug resistant(MDR) bacteria in hospital and to ensure patients′ medical safety.METHODS We had established a network monitoring system,improved MDR monitoring,enhanced management of antibiotics rational use and cut off the transmission of MDR bacteria.RESULTS After taken these measures,the standard preventing of medical workers,handwashing compliance and specimen censorship rate had been greatly improved.Antimicrobial drug use was more standardized.In the last two years,we hadn′t found any epidemic outbreak due to MDR bacteria event.CONCLUSIONS Taking comprehensive prevention and control measures can prevent and control the development and proliferation of MDR bacteria and ensure patients′ medical safety.

Abstract] Objective To investigate the in vivo therapeutic effects of an extract of herb medi-cines, YiGanQingDuKeLi, in combination with adefovir dipivoxil (ADV) on the rebound of duck hepatitis B virus ( DHBV) multiplication after withdrawal of ADV treatment.Methods Peking ducks were infected with DHBV positive serum samples for 7 days and then screened by SYBR Green real-time PCR.The ducks positive for DHBV were randomly divided into five groups including the model control group, the ADV treat-ment group, the herb treatment group, the high-dose combination therapy group and the low-dose combina-tion therapy group.The ducks in the ADV treatment and the herb treatment groups were respectively treated with distilled water and YiGanQingDuKeLi (1.2 g/ml) for 14 days after the treatment of ADV (0.25 mg/ml) for 21 days.The ducks in the high-dose group were treated with YiGanQingDuKeLi (1.2 g/ml) for 14 days after the combined treatment with high-dose YiGanQingDuKeLi (1.2 g/ml) and ADV (0.25 mg/ml) for 21 days.The ducks in the low-dose group were treated with YiGanQingDuKeLi (0.6 g/ml) for 14 days after the combined treatment with YiGanQingDuKeLi (0.6 g/ml) and ADV (0.125 mg/ml) for 21 days.Blood samples were collected from each duck via leg vein after 0, 7, 14 and 21 days of drug adminis-tration and after 7 and 14 days of drug withdrawal.The levels of DHBV-DNA, alanine aminotransferase ( ALT) and aspartate aminotransferase ( AST) in blood serum samples were detected.Results Compared with the model group, the levels of DHBV-DNA, ALT and AST in ducks from the herb treatment group and combined treatment groups were decreased before the discontinuation of ADV treatment ( P<0.05 or P<0.01).Moreover, the titers of DHBV-DNA in ducks treated with high doses of drugs were much lower than those from ADV treatment group.The levels of DHBV-DNA, ALT and AST in ducks treated with herb medi-cine and high doses of drugs remained at relatively low levels after the cessation of ADV treatment, but re-bounded significantly in ducks with ADV treatment.The levels of DHBV-DNA and ALT rebounded slightly in ducks treated with low doses of drugs as compared with those of ADV treatment group ( P<0.01 or P<0.05).Conclusion The treatment of YiGanQingDuKeLi in combination with ADV could inhibit not only the in vivo replication of DHBV, but also the rebound of DHBV multiplication after ADV withdrawal.

Objective    To investigate the feasibility and safety of non-intubation anesthesia in thoracic surgery. Methods    From September 2017 to December 2019, 296 patients were operated at department of thoracic surgery in our hospital. There were 167 males and 129 females with an average age of 50.69±12.95 years, ranging from 16 to 76 years. The patients were divided into two groups according to whether they were intubated: 150 patients were in a non-intubation group, including 83 males and 67 females with an average age of 49.91±13.59 years, ranging from 16 to 76 years, and 146 patients were in an intubation group including 84 males and 62 females with an average age of 51.49±12.26 years, ranging from 16 to 74 years. Intraoperative data, postoperative recovery, inflammatory response of the two groups were compared. Results    There was no statistical difference between the two groups in operation time, blood loss, the lowest oxygen saturation or other indicators (P>0.05). But the highest partial pressure of carbon dioxide of the non-intubation group was higher than that of the intubation group (P=0.012). The non-intubation group was superior to the intubation group in postoperative recovery and inflammatory response (P<0.05). Conclusion    The non-intubation anesthesia is safe and maneuverable in thoracic surgery, and it has some advantages in accelerating postoperative rehabilitation.
