The management of medical equipment is one of the important parts in hospital management,which management quality can directly affect the hospital central task and disciplines construction.How to strengthen the management of medical equipment are studied from the plan of medical equipment,the purchase,book building and application four aspects.

Objective To observe the anti-proliferation effects of rapamycin and paclitaxel of different hu-man prostate cancer cells in vitro. Methods The methods of MTr and flow cytometry were respectively ap-plied to observe the effect of rapamycin, paclitaxel and rapamycin+paclitaxel on proliferation and apoptosis of different prostate cancer cell lines (LNCaP-C4, LNCaP-C4-2, PC-3). Results When the concentration of rapamycin was 0.01 μmol/L, the impressive effect showed a remarkable difference in contrast to the con-trol. While in group LNCaP-C4-2 and PC-3, the goal concentration of rapamycin was 0.001μmol/L. When the concentration of paclitaxel was 0. 2 ng/mL, the impressive effect showed a remarkable difference in con-trast to the control. In group rapamycin (10 nmol/L) and in group paclitaxel (1 ng/mL) there were signifi-cant differences in growth inhibition, compared with control. While in group rapamycin(5 nmoL/L)+pacli-taxel(0.5ng/mL) there was significant difference in growth inhibition, compared with rapamycin (10 nmol/L) and paclitaxel (1 ng/mL) respectively. After cultured with rapamycin or paclitaxel alone, more tumor cells induced apoptosis than control. While after cultured with rapamycin and paclitaxel simultaneously, more tumor cells induced apoptosis than with rapamycin or paclitaxel alone. Conclusions Both rapamycin and paclitaxel had a good impressive effect on the three prostate cell lines (LNCaP-CA, LNCaP-C4-2, PC-3) with dose-dependent manner. After cultured with rapamycin and paclitaxel simultaneously, more tumor cells were induced apoptosis than with rapamycin or paclitaxel alone.

OBJECTIVETo study the influence of cytokine gene polymorphism on the incidence of acute rejection in renal transplantation.
METHODSThe cytokine genotypes of TNF-alpha, TGF-beta(1), IL-10 and IL-6 in 24 normal people and 115 consecutive renal transplant recipients were determined by PCR-SSP using sequence-specific oligonucleotide primer. The cytokine genotypes were then correlated with the incidence of acute rejection in renal transplantation.
RESULTSThe frequency of TNF-alpha and IL-10 low producer genotype in the 115 kidney recipients and control group was 88.7%, 80% and 87.5%, 75% respectively, and the frequency of TGF-beta(1) and IL-6 high producer genotype was 79.1%, 100% and 66.7%, 100% respectively. The incidence of acute rejection was higher in the recipients with TNF-(high producer or IL-10 intermediate high producer genotype than in the recipients with low producer genotype [53.8%, 43.5% vs 18.6% (chi(2) = 8.17), 17.4% (chi(2) = 7.16), P < 0.01, respectively].
CONCLUSIONThis study demonstrated that TNF-alpha and IL-10 gene polymorphism has significant influence on the incidence of acute rejection in renal transplantation.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.
