Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

With the coronavirus disease 2019(COVID-19)pandemic across the world, numerous variants have emerged.As a high-risk group for COVID-19, the elderly are prone to acute kidney injury(AKI), with atypical clinical features and high proportions of patients with critical illness.Its pathogenesis mainly includes direct damage to the kidney via the angiotensin-converting enzyme 2(ACE2)pathway, the extracellular matrix metalloproteinase inducer(CD147)pathway, and age-related renal dysfunction, inflammatory aging, immune aging and other non-specific mechanisms, which significantly increase the risk of adverse prognosis.Therefore, the establishment of an early warning system for AKI, increasing vaccination coverage, nutritional support, treatment of primary diseases, extracorporeal supportive therapy and other control measures are particularly important to prognosis improvement.This review summarized the pathogenesis, early prevention and treatment of AKI in elderly patients with COVID-19.

Objective: To systematically evaluate the efficacy and safety of CT-guided percutaneous lung puncture biopsy versus ultrasound-guided percutaneous lung puncture biopsy. Methods: Relevant domestic and foreign related databases such as PubMed, Web of Science, Cochrane Library, OVID, China Biology Medicine, VIP, Wanfang and CNKI databases were searched, the randomized controlled trial about the applications of CT-guided and ultrasound-guided percutaneous lung puncture biopsy were collected. After extracting the relevant data, a Meta-analysis was performed using RevMan 5.2 and Stata softwares. Results: Ten studies met the inclusion criteria, with a total sample size of 1 158 cases, of which 635 were CT-guided puncture biopsy and 523 were ultrasound-guided puncture biopsy. Meta-analysis showed that the difference of the success rate between the CT-guided group and the ultrasound-guided group was not statistically significant [97.48% (619/635) vs. 96.56% (505/523), RR= 1.01, 95% CI 0.99-1.03, P= 0.360]; the puncture diagnosis rate in the CT-guided group was lower than in the ultrasound-guided group, and the difference was statistically significant [92.44% (619/635) vs. 96.56% (505/523), RR= 0.97, 95% CI 0.94-0.99, P= 0.007]. The total incidence of complications after puncture in the CT-guided group was higher than that in the ultrasound-guided group, and the difference was statistically significant [14.49% (92/635) vs. 9.56% (50/523), RR= 1.56, 95% CI 1.11-2.19, P= 0.010]; the incidence of pneumothorax after puncture in the CT-guided group was higher than that in the ultrasound-guided group, and the difference was statistically significant [11.50%(73/635) vs. 6.31% (33/523), RR= 1.77, 95% CI 1.17-2.68, P= 0.007]; the difference of the incidence of bleeding after puncture between the CT-guided group and the ultrasound-guided group was not statistically significant [2.99% (19/635) vs. 3.25% (17/523), RR= 1.08, 95% CI 0.59-1.98, P= 0.800]. Conclusions Both CT-guided and ultrasound-guided percutaneous lung puncture biopsy have good clinical diagnostic value. However, for the intrapulmonary masses shown by ultrasound, the ultrasound-guided lung puncture biopsy has a shorter operation time, lower cost, and higher safety.

Radiotherapy can improve the local control rate of the tumors by destructing the tumor cells within the radiation field, can reduce the distant spread by activating the body 's anti-tumor immune response through various mechanisms, and also can exert systemic anti-tumor effect synergistically assisted by immunotherapy. As a new combination therapy, a large number of studies have found that local radiotherapy combined with different immunotherapy can benefit the survival of cancer patients. The optimal efficacy is closely related to the appropriate radiotherapy dose, segmentation model and combined timing. This paper discusses the effects of radiotherapy on the immune system, the related basic and clinical researches of radiotherapy and immunotherapy, and the better way to make the combination effectively.

Objective: To investigate the clinical significance of tumor associated macrophages (TAM) in multiple myeloma (MM) and the relationship with angiogenesis and immunosuppression. Methods: Seventy cases of MM patients diagnosed from August 2015 to June 2017 were enrolled in the study as experimental group, 20 cases of benign hematological diseases (13 with iron deficiency anemia and 7 with megaloblastic anemia) patients as control group. Immunohistochemical method was used to detect the expression of CD163, CD34 and VEGF in bone marrow samples, and flow cytometry was used to detect the proportion of regulatory T cell (Treg cells), ELISA was used to detect the level of IL-10, and the clinical features were analyzed. Results: ①Among the 70 patients, there were 31 males and 39 females with a median age of 65 (50~78) years old. TAM infiltration density, microvascular density (MVD), VEGF expression level, Treg ratio and IL-10 level in bone marrow samples of 70 MM patients were significantly higher than those of benign hematological diseases (P<0.05). ②In the MM group, the above indexes of the patients with disease stabilized (15 cases) were lower than those of the newly diagnosed group (35 cases) and the relapse refractory group (20 cases) (P<0.05), those of relapse refractory group were higher than those of newly diagnosed group (P>0.05). ③Of the 35 newly diagnosed MM patients, 27 completed 4 courses of treatment. In the effective group (15 cases), the TAM infiltration density after treatment was significantly lower than that before treatment, the difference was statistically significant[(20.20±7.66) vs (28.87±11.97), t=2.362, P=0.025]; while in the ineffective group of 12 cases, the difference of the TAM infiltration density before and after treatment was not statistically significant[(42.00±13.76) vs (48.25±13.59), t=1.119, P=0.275]. ④TAM infiltration density in the effective group after bortezomib treatment (21 cases) were lower than those in the non-bortezomib treatment group (18 cases)[(16.52 ±4.26) vs (19.27 ±5.82), t=1.662, P=0.170]. ⑤The TAM infiltration density in MM patients was positively correlated with MVD, VEGF expression level, Treg cell ratio and IL-10 level (P<0.001). Conclusion The infiltration of TAM in the microenvironment of MM, which may promoting angiogenesis and inhibiting immune response, is related to the occurrence, development, therapeutic effect and drug resistance of MM.

Objective:To detect the proportion of lymphocyte subsets in peripheral blood of the ad-vanced breast cancer patients before and after chemotherapy with docetaxel and thiotepa,as well as the association between the proportion of peripheral blood lymphocyte subsets with the response rate and prog-nosis.Methods:The proportions of lymphocyte subsets (CD3 +T cell,CD3 +/CD4 +T cell,CD3 +/CD8 +T cell,CD3 -/CD16 +56 +NK cell,CD3 +/CD16 +56 +T cell,CD19 +B cell,CD4 +/CD25 +T cell,CD8 +/CD28 -T cell,CD8 +/CD28 +T cell)in the peripheral blood of 86 patients were analyzed with flowcytometry before and after chemotherapy.The result was analyzed in combination with clinico-pathological data.Results:The proportion of regulatory T cells (Treg)after chemotherapy in the disease control patients decreased significantly compared with that of the progressive patients (P=0.034).The difference of the proportions of Treg before and after chemotherapy affected significantly the overall survi-val (OS).The OS of the patients with decreased proportion of Treg was significantly longer than that of the patients with increased proportion of Treg,which was 23.5 and 9.4 months respectively (P<0.05). Conclusion:The patients with decreased proportion of Treg after chemotherapy had higher response rate and better survival benefit.
