OBJECTIVE To observe the preventive and therapeutic effect of Ganoderma lucidum spore powder on cancer-related fatigue in postoperative adjuvant chemotherapy patients with breast cancer, and to provide a basis for using traditional Chinese medicine processed by modern processing to effectively improve the quality of life of cancer patients. METHODS Seventy-four female patients who received postoperative adjuvant chemotherapy for breast cancer in Zhejiang Cancer Hospital from November 2021 to March 2023 were randomly divided into either treatment(n=37) or control group(n=37). Both groups were given 4 cycles of epirubicin(or liposomal doxorubicin) combined with cyclophosphamide adjuvant chemotherapy and corresponding symptomatic treatment: the treatment group was treated with sporoderm-removed Ganoderma lucidum spore powder 2 g·d–1, and the control group was treated with placebo. The incidence and severity of cancer-related fatigue, the changes in T lymphocyte subsets, serum inflammatory factors, intestinal flora, and the effects of drugs on blood routine, liver, and kidney function were compared between the two groups after treatment. RESULTS The incidence of cancer-related fatigue and the score of the Piper correction scale in the treatment group were significantly lower than those in the control group(P<0.05), the proportion of CD3+, CD4+, and CD3-CD56+ was significantly higher than that in the control group(P<0.05), while the proportion of CD8+ was significantly lower than that in the control group(P<0.05). The counts of IL-2 and IL-10 were higher than those in the control group, while the counts of IL-6, IL-8, and CRP were lower than those in the control group(P<0.05). The counts of leukocytes, neutrophils, and platelets in the control group were significantly higher than those in the control group(P<0.05), and the abundance of intestinal microflora in the control group was higher than that in the control group. There was no significant difference in liver and kidney function between the 2 groups. CONCLUSION Sporoderm-removed Ganoderma lucidum spore powder can significantly reduce the incidence and level of cancer-related fatigue in breast cancer patients during adjuvant chemotherapy, inhibit inflammatory factors, regulate intestinal flora and body immunity.

OBJECTIVE To study the therapeutic effect of saikosaponins and paeoniflorin on rats with premenstrual dysphoric disorder(PMDD) model of liver Qi depression and the effect on neurotransmitters in hippocampal brain area. METHODS The PMDD rat model of liver Qi depression was prepared by the time-chosen chronic restraint stress method, and the depressive symptoms of rats were evaluated by the intervention of saikosaponins and paeoniflorin, the open field experiment and forced swimming experiment, and the changes of neurotransmitter levels in the hippocampal brain region of rats were detected by UHPLC-MS/MS target metabolomics. RESULTS The levels of 5-HT, Glu, GABA and NE in the hippocampal brain area of PMDD rats were significantly increased, and the levels of 5-HT, Glu, GABA, NE, DA and E were not statistically significant from those of the normal group after the intervention of saikosaponins and paeoniflorin. CONCLUSION Saikosaponins and paeoniflorin alleviates depression in rats with PMDD by regulating neurotransmitter levels, and it may be the pathway for the clinical treatment of PMDD with liver qi depression in the formulations of Bupleuri Radix and Paeoniae Radix Alba.

Objective:To evaluate the application of metagenomic next-generation sequencing (mNGS) in the diagnosis of osteoarticular infection.Methods:The clinical data of 37 inpatients aged 32-90 year with osteoarticular infection admitted in the Department of Spine Surgery of Qingdao Chest Hospital from January to December 2019 were retrospectively analyzed. There were 31 cases of spine infection and 6 cases of other joint infection. The tissue samples were obtained from the infected sites through puncture or surgical approach in all patients. The tissue samples were subjected to routine culture of mycobacteria, aerobic bacteria and anaerobic bacteria, respectively. The gene amplification and mNGS were performed for detection of mycobacterium tuberculosis DNA (MTB-DNA). The chi-square test or Fisher’s exact test were used to compare the detection rates of pathogen and simple bacterial infection between mNGS and conventional culture. The conventional culture, mNGS and MTB-DNA amplification detection were performed for all samples; with clinical diagnosis as the gold standard, the diagnostic values of 3 methods were evaluated with receiver operating characteristic curve (ROC). Paired sample t test was used to compare white blood cell(WBC) count, erythrocyte sedimentation rate, C-reactive protein of patients before and after treatment. P<0.05 was considered statistically significant. Results:The pathogens were detected by mNGS for 42 times: bacteria for 39 times (92.8%), fungi for twice (4.8%) and Kirks body for once (2.4%). Among 37 patients there were 29 cases of pure bacterial infection (78.4%), 2 cases of pure fungi infection (5.4%), 1 case of pure Kirks body infection (2.7%), and 5 cases of mixed infection of two or more pathogens (13.5%). The detection rates of mNGS and conventional culture were 100.0% (37/37) and 67.6% (25/37), respectively ( χ2=13.987, P<0.05). The detection rates of mNGS and conventional culture in 29 patients with pure bacterial infection were 100.0% (29/29) and 69.0% (20/29), respectively ( χ2=16.913, P<0.05). The area under the ROC curve (AUC) of conventional culture, mNGS, and MTB-DNA in the diagnosis of osteoarticular tuberculosis infection was 0.958 (95% CI: 0.866-1.000, P<0.05), 1.000 (95% CI: 1.000-1.000, P<0.05) and 0.958 (95% CI: 0.866-1.000, P<0.05). All the 37 patients were treated with anti-infective drugs according to the results of mNGS and conventional culture. Among them, 28 patients received surgical intervention. The patients were followed up until April 30, 2020, 1 patient died. After 3 months of follow-up, the WBC count, erythrocyte sedimentation rate and C-reactive protein were (5.5±1.5)×10 9/L, (41±38)mm/h and (5.0±4.6) mg/L, respectively, which were lower than those before anti-infection treatment [(8.0±2.9)×10 9/L, (79±42)mm/h and(63±52)mg/L] ( t=6.536, 8.302 and 6.373, all P<0.05). Conclusion:The metagenomic next-generation sequencing may have important clinical value in the differential diagnosis of osteoarticular infection.

In order to underst and the status of health emergency personnel training development and raising coping measures, electronic questionnaire surveys were conducted among 22 colleges and universities in different region of China. The result showed that colleges universities in China invested less in the training of emergency personnel. It is different and emphasized particularly for the cultivation of emergency professional ability among different types of public health students. Universities and employer hold relative evaluation of students′ emergency professional ability with distinct regional differences.

In order to understand the status of the cultivation of the masters of public health (MPH) in colleges in China and improve the cultivation model, an electronic questionnaire survey were conducted among 22 schools of public health in colleges. The result showed that the size and the enrolment scale of Chinese MPH students were relatively small, and the training objectives were still unclear. There was no obvious difference between the curriculum setting for MPH and academic master degree. The practical skill-oriented courses and emergency response ability of public health practice were insufficient. The cultivation model of MPH should be improved in future.

To investigate the current status of postgraduates training in public health and preventive medicine in China. In this study, a questionnaire survey was conducted among directors of enrollment and teaching in 22 universities with postgraduate admission qualifications in corresponding disciplines nationwide. In 2016, full-time postgraduates were mainly academic masters. In addition to the graduate entrance examination, the common enrollment mode in colleges was to enroll a high qualified student with recommendations from relevant experts or institutions and an exemption from entrance examination (20/22). The emphasis on training contents between academic and public health master was different. Currently, the scale of public health postgraduate enrollment in public health and preventive medicine in China is stable, and the training program is reasonable, but there is an issue of monotonous model and uneven distribution of enrollment.

Objective: To investigate the effects of interferon inducible protein 16 (IFI16), a cytosolic DNA sensor, on the expression of human T-cell leukemia virus type 1 (HTLV-1) proteins and pro-inflammatory cytokines in adult HTLV-1-positive T cells. Methods: IFI16 expression in different HTLV-1-positive T cell lines was detected by immunoblot assay. Specific siRNA targeting the IFI16 gene was constructed and the gene silencing efficiency was detected by immunoblot assay. Expression of HTLV-1 Tax protein at mRNA and protein levels was respectively detected by real-time PCR and immunoblot assay after knocking down the expression of IFI16 in HTLV-1-positive T cells with siRNA. Expression of interferon (IFN)-α, IFN-γ, tumor necrosis factor (TNF)-α, Tax and Env were detected by real-time PCR. Results: Compared with the HTLV-1-negative T cell line Jurkat, IFI16 expression was enhanced in the HTLV-1-positive T cell lines MT2, MT4 and C8166. Tax expression was increased, while that of IFN-α, IFN-γ and TNF-α was decreased in MT2 and MT4 cells after silencing the expression of IFI16 with siRNA. Conclusions IFI16 expression was increased in HTLV-1-positive MT2 and MT4 cells. Meanwhile, IFI16 promoted the production of interferon and pro-inflammatory cytokines and inhibited the expression of HTLV-1 proteins.
