Abstract
Objective: To evaluate the effect of Wendler Glottoplasty to elevate vocal pitch in transgender women. Methods: The voice parameters of pre-and 3-month post-surgery of 29 transgender women who underwent Wendler Glottoplasty in department of otorhinolaryngology head and neck surgery of Beijing Friendship Hospital from January, 2017 to October, 2020 were retrospectively analyzed. The 29 transgender women ranged in age from 19-47 (27.0±6.3) years old. Subjective evaluation was performed using Transsexual Voice Questionnaire for Male to Female (TVQMtF). Objective parameters included fundamental frequency (F0), highest pitch, lowest pitch, habitual volume, Jitter, Shimmer, maximal phonation time (MPT), noise to harmonic ratio (NHR) and formants frequencies(F1, F2, F3, F4). SPSS 25.0 software was used for statistically analysis. Results: Three months after surgery, the score of TVQMtF was significantly decreased [(89.9±14.7) vs. (50.4±13.6), t=11.49, P<0.001]. The F0 was significantly elevated [(152.7±23.3) Hz vs. (207.7±45.9) Hz, t=-6.03, P<0.001]. Frequencies of F1, F2 and F3 were significantly elevated. No statistical difference was observed in the frequencies of F4. The highest pitch was not significantly altered while the lowest pitch was significantly elevated [(96.8±17.7) Hz vs. (120.0±28.9) Hz, t=-3.71, P=0.001]. Habitual speech volume was significantly increased [(60.0±5.2) dB vs. (63.6±9.6) dB, t=-2.12, P=0.043]. Jitter, Shimmer, NHR and MPT were not obviously altered (P>0.05). Conclusions: Wendler Glottoplasty could notably elevate the vocal pitch, formants frequencies and degree of vocal femininity in transgender women without affecting phonation ability and voice quality. It can be an effective treatment modality for voice feminization.

Abstract
Introduction Most T cell receptor (TCR)Vβ chain-expressing T cell lymphomas (TCL) including those caused by Human T cell leukaemia virus type-1 (HTLV-1) have poor prognosis. We hypothesised that chimeric antigen receptor (CAR)-mediated targeting of the clonal, lymphoma-associated TCRβ chains would comprise an effective cell therapy for TCL that would minimally impact the physiological TCR repertoire. Methods As proof of concept, we generated CAR constructs to target four TCRVβ subunits. Efficacy of the CAR constructs was tested using conventional T cells as effectors (CAR-T). Since invariant NKT (iNKT) cell do not incite acute graft-versus-host disease and are suitable for 'off-the-shelf' immunotherapy, we generated anti-TCRVβ CAR-iNKT cells. Results We show that anti-TCRVβ CAR-T cells selectively kill their cognate tumour targets while leaving >90% of the physiological TCR repertoire intact. CAR-iNKT cells inhibited the growth of TCL in vivo, and were also selectively active against malignant cells from Adult T cell leukaemia/lymphoma patients without activating expression of HTLV-1. Discussion Thus we provide proof-of-concept for effective and selective anti-TCRVβ CAR-T and -iNKT cell-based therapy of TCL with the latter providing the option for 'off-the-shelf' immunotherapy.

Abstract
UNLABELLED The dried root of Glehnia littoralis is a traditional Chinese herbal medicine mainly used to treat lung diseases and plays an important role in fighting coronavirus disease 2019 pneumonia in China. This study focused on the key enzyme gene GlPS1 for furanocoumarin synthesis in G. littoralis. In the 35S:GlPS1 transgenic Arabidopsis study, the Arabidopsis thaliana-overexpressing GlPS1 gene was more salt-tolerant than Arabidopsis in the blank group. Metabolomics analysis showed 30 differential metabolites in Arabidopsis, which overexpressed the GlPS1 gene. Twelve coumarin compounds were significantly upregulated, and six of these coumarin compounds were not detected in the blank group. Among these differential coumarin metabolites, isopimpinellin and aesculetin have been annotated by the Kyoto Encyclopedia of Genes and Genomes and isopimpinellin was not detected in the blank group. Through structural comparison, imperatorin was formed by dehydration and condensation of zanthotoxol and a molecule of isoprenol, and the difference between them was only one isoprene. Results showed that the GlPS1 gene positively regulated the synthesis of coumarin metabolites in A. thaliana and at the same time improved the salt tolerance of A. thaliana.

Abstract
Objective: To analyze the epidemiology and spatial-temporal distribution characteristics of hand, foot and mouth disease (HFMD) in Shanxi province. Methods: The data of HFMD in Shanxi province from 2009 to 2020 were collected from notifiable disease management information system of Chinese information system for disease control and prevention and analyzed by descriptive epidemiology, Joinpoint regression, spatial autocorrelation analysis and spatio- temporal scanning analysis. Results: A total of 293 477 HFMD cases were reported in Shanxi province from 2009 to 2020, with an average annual incidence of 67.64/100 000 (293 477/433 867 454), severe disease rate of 5.36/100 000 (2 326/433 867 454), severe disease ratio of 0.79%(2 326/293 477), mortality of 0.015/100 000 (66/433 867 454), and fatality rate of 22.49/100 000 (66/293 477). The reported incidence rate, severe disease rate, mortality rate and fatality rate of HFMD showed decreasing trends. The main high-risk groups were scattered children and kindergarten children aged 0-5. The incidence of HFMD had obvious seasonal variation, with two peaks every year: the main peak was during June-July, the secondary peak was during September-October and the peak period is from April to November. A total of 13 942 laboratory cases were confirmed, with a diagnosis rate of 4.75% (13 942/293 477), including 4 438 (35.11%, 4 438/293 477) Enterovirus A71 (EV-A71) positive cases, 4 609 (33.06%, 4 609/293 477) Coxsackievirus A16 (CV-A16) positive cases, and 4 895 (31.83%, 4 895/293 477) other enterovirus positive cases. There was a spatial positive correlation (Moran's I ranged from 0.12 to 0.58, all P<0.05) and the spatial clustering was obvious. High-risk regions were mainly distributed in Taiyuan in central Shanxi province, Linfen and Yuncheng in southern Shanxi province, and Changzhi in southeastern Shanxi province. Spatial-temporal scanning analysis revealed 1 the most likely cluster and 8 secondary likely clusters, of which the most likely cluster (RR=2.65, LLR=22 387.42, P<0.001) located in Taiyuan and Jinzhong city, Shanxi province, including 12 counties (districts), and accumulated from April 1, 2009 to November 30, 2018. Conclusions: There was obvious spatial-temporal clustering of HFMD in Shanxi province, and the epidemic situation was in decline. The key areas were the districts in urban areas and the counties adjacent to it. Meanwhile, the monitoring and classification of other enterovirus types of HFMD should be strengthened.

Abstract
Objective: To compare the efficacy, safety, and influencing factors among children with hepatitis B virus e antigen (HBeAg)-positive chronic hepatitis B (CHB) who received short-term therapy with pegylated interferon alfa-2a (Peg-IFNα-2a) or continuous therapy with entecavir (ETV). Methods: Quantitative data were compared using analysis of variance to compare the differences between groups. Enumeration data were compared by χ2 test (or Fisher's exact test). Univariate and multivariate logistic regressions were used to analyze the influencing factors. Results: Peg-IFNα-2a, ETV, and untreated group had HBsAg clearance rates of 46.2%, 5.3%, and 0 after 52 weeks of therapy, respectively. HBsAg clearance in the patients' group with Peg-IFNα-2a and ETV was all accompanied by anti-HBS positive conversion, and the difference was statistically significant (χ2=13.616, P=0.001). Peg-IFNα-2a group was followed-up for 104 weeks. Peg-IFNα-2a, ETV, and the untreated group had HBsAg clearance rates of 46.2%, 10.5%, and 0%, respectively, and the differences were statistically significant (χ2=11.056, P=0.004). Only one of the two children with HBsAg clearance in the ETV group had achieved anti-HBs antibodies, and the difference was statistically significant (χ2=13.616, P=0.001). Univariate and multivariate logistic regression analysis showed that HBsAg clearance was associated with age and antiviral therapy. During treatment, adverse events such as fever (n=4, 30.8%), rash (n=4, 30.8%), fatigue (n=1, 7.7%), leukopenia (n=7, 53.8%), arthritis (n=1, 7.7%), and alopecia (n=3, 23.1%) were observed in the Peg-IFNα-2a group, while none were observed in the ETV group. Conclusion: Peg-IFNα-2a antiviral therapy produced higher HBsAg clearance than ETV in five-year-old and younger children with HBeAg-positive CHB, while ETV had fewer adverse events and was safer than Peg-IFNα-2a.

Abstract
Objective: To summarize the clinical features, management and outcome of superior vena cava syndrome (SVCS) associated with mediastinal malignancy in children. Methods: Clinical data of 42 children of SVSC associated with mediastinal malignancy in Shanghai Children's Medical Center from January 2015 to December 2021 were collected and analyzed retrospectively. The clinical manifestations, pathological diagnosis, disease diagnosis process, and prognosis were summarized. Results: Among 42 children of SVCS associated with mediastinal malignancy, there were 31 males and 11 females. The age at diagnosis was 8.5 (1.9, 14.9) years. Cough and wheezing (33 cases, 79%), orthopnea (19 cases, 45%) and facial edema (18 cases, 43%) occurred most commonly. T-cell lymphoblastic lymphoma (T-LBL) was the most frequent pathological diagnosis (25 cases, 60%), followed by T-cell acute lymphoblastic leukemia (T-ALL) (7 cases, 17%), anaplastic large cell lymphoma (4 cases, 10%) and diffuse large B-cell lymphoma (2 cases, 5%), peripheral T-lymphoma, Hodgkin lymphoma, Ewing's sarcoma and germ cell tumor (1 case each). Pathological diagnosis was confirmed by bone marrow aspiration or thoracentesis in 14 cases, peripheral lymph node biopsy in 6 cases, and mediastinal biopsy in 22 cases. Twenty-seven cases (64%) had local anesthesia. Respiratory complications due to mediastinal mass developed in 3 of 15 cases who received general anesthesia. Of the 42 cases, 27 cases had sustained remission, 1 case survived with second-line therapy after recurrence, and 14 cases died (2 cases died of perioperative complications and 12 cases died of recurrence or progression of primary disease). The follow-up time was 36.7 (1.2, 76.1) months for 27 cases in continuous complete remission. The 3-year overall survival (OS) and events free survival (EFS) rates of 42 children were 59% (95%CI 44%-79%) and 58% (95%CI 44%-77%) respectively. Conclusions: SVCS associated with mediastinal malignancy in children is a life-threatening tumor emergency with high mortality. The most common primary disease is T-LBL. The most common clinical symptoms and signs are cough, wheezing, orthopnea and facial edema. Clinical management should be based on the premise of stable critical condition and confirm the pathological diagnosis through minimal invasive operation.

Abstract
Vaccinia virus (VACV) encodes scores of proteins that suppress host innate immunity and many of these target intracellular signalling pathways leading to activation of inflammation. The transcription factor NF-κB plays a critical role in the host response to infection and is targeted by many viruses, including VACV that encodes 12 NF-κB inhibitors that interfere at different stages in this signalling pathway. Here we report that VACV proteins C2 and F3 are additional inhibitors of this pathway. C2 and F3 are BTB-Kelch proteins that are expressed early during infection, are non-essential for virus replication, but affect the outcome of infection in vivo. Using reporter gene assays, RT-qPCR analyses of endogenous gene expression, and ELISA, these BTB-Kelch proteins are shown here to diminish NF-κB activation by reducing translocation of p65 into the nucleus. C2 and F3 are the 13th and 14th NF-κB inhibitors encoded by VACV. Remarkably, in every case tested, these individual proteins affect virulence in vivo and therefore have non-redundant functions. Lastly, immunisation with a VACV strain lacking C2 induced a stronger CD8+ T cell response and better protection against virus challenge.

Abstract
Objective: A method to determine chlorobenzene metabolite-p-chlorophenol in urine by solid phase extraction-gas chromatography was established. Methods: In May 2021, the urine sample was hydrolyzed at 100 ℃ for 1.5 h with 2 ml concentrated hydrochloric acid. After cooling and filtering, the sample was enriched and purified by Oasis(®)MAX 6cc SPE column. Drip washing with 0.01 mol/L hydrochloric acid solution and elution with acetonitrile, the eluent was volumized to 5 ml with acetonitrile and determined by gas chromatography, and quantify by standard curve method. Results: Calibration curve of the method was linear within the range of 1.61-80.30 μg/ml and showed good linearity with r=0.9997, the regression equation was y=1.51602x-0.10234. The determination limit was 0.17 μg/ml, and the limit of quantitation was 0.55 μg/ml. Recovery rates were between 89.3%-104.4%, the relative standard deviation (RSD) of intra-day measurements ranged from 4.3% to 6.7%, and the RSD of inter-day measurements ranged from 4.5% to 6.7%. Conclusion: This method could optimize sample pretreatment, and eliminate the interference of impurities, which is sensitive, efficient and accurate for the determination of chlorobenzene metabolite-p-chlorophenol in urine.

Abstract
BACKGROUND We evaluated the non-inferiority of nedaplatin-based and cisplatin-based concurrent chemoradiotherapy in cervical cancer patients. DESIGN Patients aged 28-82 years with pathologically diagnosed cervical cancer (stage IB-IVA) were randomly chosen for the study. Patients in both the cisplatin and nedaplatin groups received radiotherapy and weekly intravenous nedaplatin 30 mg/m2 or cisplatin 40 mg/m2 concurrently. RESULTS One hundred and sixty patients who received treatment between 10 May 2018 and 31 August 2020 were included. The 3-year overall survival in the nedaplatin group (median 30.5 months) was not significantly different from that in the cisplatin group (28.5 months; hazard ratio 0.131, 95% confidence interval 0.016-1.068; P = 0.058). No significant differences in hematological toxicity were observed between the two groups. Vomiting (40 versus 61), nausea (44 versus 67), and anorexia (52 versus 71) were more common in the cisplatin group whereas effects on liver function, including total bilirubin (7 versus 3), alanine aminotransferase (7 versus 2), and aspartate aminotransferase (6 versus 2), were more common in the nedaplatin group. Four patients in the cisplatin group had grade I creatinine elevation, whereas none in the nedaplatin group had abnormal creatinine levels. Two patients in the nedaplatin group discontinued concurrent chemotherapy because of infusion, and one patient in the cisplatin group discontinued treatment because of infusion-induced dizziness. CONCLUSIONS Our findings suggest that nedaplatin has a milder gastrointestinal reaction but a more significant effect on liver function than cisplatin. In patients with cervical cancer, nedaplatin-based concurrent chemoradiotherapy could serve as an alternative treatment to cisplatin.

Abstract
Bacterioplankton community is the major engine that drives the biogeochemical cycling of various nutrient and essential elements in the coastal ecosystem. Unraveling the mechanisms governing the succession of such complex bacterioplankton communities in dynamic environment is a challenging issue in environmental science. In this study, we investigated the diversity patterns and succession mechanisms of both free-living and particle-attached bacterioplankton communities that have been exposed to low oxygen and typhoon Lekima. The community evenness was the lowest in August when the temperature was high and dissolved oxygen was low. Similar patterns in community succession were observed for free-living and particle-attached bacterioplankton community after the passing through of typhoon Lekima. Both the free-living and particle-attached bacterioplankton communities in the surface and bottom water columns were strongly affected by geo-environmental factors, among which temperature was the common factor, suggesting that the metabolic theory of ecology also underlie the dynamic patterns of bacterioplankton communities. Although the surface and bottom bacterioplankton compositions were initially different taxonomically and shaped by different environmental conditions, they followed a similar succession pattern over the sampling months. Temperature, dissolved inorganic carbon and dissolved inorganic phosphorus were the major factors associated with the variations of surface bacterioplankton ASVs. Time-decay relationship, in which community similarity decreases with increasing time interval, was clearly observed. Such pattern shall be attributed to the combined effects of time and the changing environmental factors over the sampling months, rather than time alone. Integrating multiple lines of evidences, we demonstrated that determinism governed the succession of both free-living and particle-attached bacterioplankton communities in the coastal maricultural ecosystem, with higher stochastic ratio in habitable months (i.e. fall). This study is expected to provide valuable mechanistic insights into the succession of disturbed complex bacterioplankton communities.

Methods: We retrospective analyzed patients confirmed with COVID-19 in the Fifth Medical Center of the People’s Liberation Army (PLA) General Hospital between February to April 2020, selected a total of 58 (N) patients with lab and imaging examinations that met the study criteria, using Artificial intelligence (AI) software to calculate the percentage of COVID-19 lesions in the volume of the whole lung, then the correlations of general information, initial chest CT examination after admission and laboratory examinations were analyzed. Results: The 58 (N) COVID-19 patients were divided into mild group [41(n) cases]: and severe group [17(n) cases]: according to patient’s condition. CT findings of the severe group and mild group mainly included single or multiple ground glass opacity (GGO), with lesions mainly distributed in the periphery of lungs or GGO mixed with consolidation, with lesions involved in peripheral and central areas of both lungs, accompanied other signs. A significant difference in CRP, IL-6, D-D, GGT was observed between the two groups (p < 0.05). The ratios regarding lymphocyte abnormality and neutrophil abnormality in the severe group were higher than those in the mild group (p < 0.05). Conclusion: The CT features at initial diagnosis of COVID-19 were mainly characterized by multiple GGO with or without partial consolidation in both lungs, with the lesions mainly distributed at the subpleural regions. Some lab test indexes were correlated with the clinical types of COVID-19.

Abstract
Introduction
Goal attainment scaling (GAS) is a method to assess the patient experience of whether a treatment is successful and capture outcomes across a diverse range of goal areas. However, this approach has not yet been used in assessing the treatment of Major Depressive Disorder (MDD) in Japan. GAS was first developed by Kiresuk and Sherman in the 1968, it is increasingly recognised as a sensitive method for recording patient-centred outcomes throughout the course of treatment.
Objectives
To demonstrate the effectiveness of vortioxetine on patient’s goal achievement and depressive symptoms, emotional, cognitive, overall function and quality of life.
Methods
VGOAL-J is a prospective, multi-center, observational cohort study of outpatients initiating vortioxetine treatment for MDD in Japan. Patients with a diagnosis of MDD according to DSM-5 who are 18 to 65 years will be enrolled from 20 sites in Japan and followed for 24 weeks. A total number of 120 patients is planned for enrolment. Primary outcome measures are GAS-D, WPAI, secondary outcome measures include Montgomery – Åsberg Depression Rating Scale (MADRS), Sheehan Disability Scale (SDS), Perceived Deficits Questionnaire-Depression 5-item (PDQ-D-5), Oxford Depression Questionnaire (ODQ), EuroQol-5 Dimension (EQ-5D). Safety will be also assessed with Adverse Events collected during the study.
Results
The results will be disseminated in late 2022 and provide new insights on GAS-D as an effective strategy to assess MDD treatment in Japan.
Conclusions
We expect to observe patients treated with vortioxetine achieving their treatment goals as assessed by GAS-D and improvements on patient- and clinician-reported measures in real-world settings.

Abstract
Objective: To explore the safety and effectiveness of stereotactic body radiation therapy (SBRT) for oligometastases from colorectal cancer (CRC). Methods: This is a prospective, single-arm phase Ⅱ trial. Patients who had histologically proven CRC, 1 to 5 detectable liver or lung metastatic lesions with maximum diameter of any metastases ≤5 cm were eligible. SBRT was delivered to all lesions. The primary endpoint was 3-year local control (LC). The secondary endpoints were treatment-related acute toxicities of grade 3 and above, 1-year and 3-year overall survival (OS) and progression free survival (PFS). Survival analysis was performed using the Kaplan-Meier method and Log rank test. Results: Petients from 2016 to 2019 who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Forty-eight patients with 60 lesions were enrolled, including 37 liver lesions and 23 lung lesions. Forty-six patients had 1 or 2 lesions, with median diameter of 1.3 cm, the median biologically effective dose (BED(10)) was 100.0 Gy. The median follow-up was 19.5 months for all lesions. Twenty-five lesions developed local failure, the median local progression free survival was 15 months. The 1-year LC, OS and PFS was 70.2% (95% CI, 63.7%~76.7%), 89.0% (95% CI, 84.3%~93.7%) and 40.4% (95%CI, 33.0%~47.8%). The univariate analysis revealed that planning target volume (PTV) and total dose were independent prognostic factors of LC (P<0.05). For liver and lung lesions, the 1-year LC, OS and PFS was 58.7% and 89.4% (P=0.015), 89.3% and 86.5% (P=0.732), 30.5% and 65.6% (P=0.024), respectively. No patients developed acute toxicity of grade 3 and above. Conclusion: SBRT is safe and effective treatment method for oligometastases from CRC under precise respiratory motion management and robust quality assurance.

Nitrogen-rich carbon quantum dots (N-CQDs) based on natural deep eutectic solvents: Simultaneous detection and treatment of trace Co 2+ under saline conditions. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 811:152389.

Abstract
Trace Co2+, when present in large quantities, is harmful to the environment and therefore cannot be ignored. Inductively coupled plasma mass spectrometry (ICP-MS) is a standard method used to detect metal ions, however, detecting trace Co2+ under high saline conditions can be challenging. Similarly, existing Co2+ treatment methods are prone to secondary pollution and have high energy consumption. Therefore, it is necessary to find an efficient and non-polluting method for Co2+ detection and treatment. This study successfully synthesized nitrogen-rich carbon quantum dots (N-CQDs) based on natural deep eutectic solvents (NADES) using a one-step solvothermal method. The prepared N-CQDs exhibited excellent fluorescence and high salt tolerance. The simultaneous detection and treatment of trace Co2+ in water under high salinity conditions were achieved for the first time. The response of the N-CQDs to Co2+ under saline condition was linear in the range of 5-250 μM with a limit of detection (LOD) of 1.2269 μM. Feasibility of practical application was assessed by quantitative detection of Co2+ in real water samples. Furthermore, the N-CQDs can treat Co2+, and the removal rate was 99.98%.

Abstract
Pseudorabies (PR) is a disease that is seriously endangering the pig industry in China. To understand the current prevalence of pseudorabies virus (PRV) in Shandong Province, China, 19,292 serum samples were collected from 16 locations in Shandong from 2018 to 2020. The gE antibody was detected by enzyme-linked immunosorbent assay. Ninety-seven suspected cases of PRV infection were collected from sick pigs vaccinated with Bartha-K61 to isolate PRV. The results showed that the average positive rate of the PRV gE antibody decreased from 38.20% in 2018 to 18.12% in 2020, but there was a high positive rate in sows. The isolation rate of PRV was 13.40% (13/97), and four strains were purified through plaque assay (named PRV-SD1, PRV-SD2, PRV-SD3, and PRV-SD4). The homology and genetic evolution of four PRV strains based on gE, gC, gI, and TK genes were analyzed and showed that these four strains shared more than 99.0% nucleotide homology with the variant PRV XJ5 strain, and they clustered in the same sub-branch with the domestic variant PRV strains, including JS-2012 and XJ5. Furthermore, the pathogenicity of the isolated variant strain was assessed by intranasal infection of 16-week-old pigs with 1 mL PRV-SD1 strain. The results of the animal experiment demonstrated that the PRV-SD1–infected pigs exhibited obvious clinical symptoms as early as 2 days post inoculation (dpi), and all infected pigs died within 1 week. The severe hyperemia of meninges and swelling of lungs and tonsils were observed. Histopathology analysis showed the obvious lymphocytes necrosis of tonsils, interstitial pneumonia, and viral encephalitis. Many positive staining cells were observed in tonsils and brains through immunohistochemistry staining assay. Viral shedding in oropharyngeal and rectal swabs were detected at 2 dpi, reached a peak at 3 dpi, and then gradually decreased. The detection of viral loads in the tissues showed that tonsils had the highest virus titer, further proving it may be the target organ of variant PRV infection. In conclusion, variant PRV strains were still highly prevalent in Shandong Province, and they had a strong pathogenicity in pigs.

Abstract
Spreading olivine powder in seawater to enhance alkalinity through weathering reactions has been proposed as a potential solution to control atmospheric CO2 concentration. Attention has usually been paid to the chemical properties of seawater after the addition of olivine within lab and modeling studies. However, both microbial acclimation and evolution in such manipulated natural environments are often overlooked, yet they are of great importance for understanding the biological consequences of whether olivine addition is a feasible approach to mitigating climate change. In this study, an olivine addition experiment was conducted to investigate variation in bacterial diversity and community composition in the surface and bottom seawater of a representative marine ranch area in the Muping, Yantai. The results show that the composition of the particle-attached microbial community was particularly affected by the application of olivine. The relative abundance of biofilm-forming microbes in particle-attached fraction increased after the addition of olivine, while no significant variation in the free-living bacterial community was observed. Our study suggests that olivine addition would reshape the bacterial community structure, especially in particle-attached microenvironments. Therefore, the risk evaluation of alkalinity enhancement should be further studied before its large-scale application as a potential ocean geoengineering plan.
