[A case of silicosis complicated with non-tuberculous mycobacterium pulmonary disease].

Non-tuberculosis mycobacterium (NTM) refers to a general term for a large group of mycobacteria, excluding the mycobacterium tuberculosis and mycobacterium leprae, which is an opportunistic pathogen. NTM pulmonary disease and pulmonary tuberculosis have very similar clinical and imaging manifestations. Ordinary sputum tests can not distinguish between mycobacterium tuberculosis and NTM accurately, and it needs to be differentiated through detection methods such as mycobacterium culture medium, high-performance liquid chromatography, and molecular biology. During the diagnosis of occupational pneumoconiosis, a sandblasting and polishing worker's lung CT showed dynamic changes in infiltrating shadows and cavities in the right lung. A sputum drug sensitivity test showed NTM infection, but the patient refused treatment. After 20 months, the CT examination of the lung showed further enlargement of infiltrating shadows and cavities, and NTM bacterial identification showed intracellular mycobacterial infection. Amikacin, moxifloxacin, azithromycin, and ethambutol combined antibacterial treatment were given. Currently, the patient is still under treatment.

[Research progress on proactive healthy lifestyle and disease immunoprevention].

The paradox of increasing health needs and limited health resources prompted a change in the traditional concept of disease prevention and control, and the concept of proactive health has emerged. Proactive health aimed to prevent and control disease and improve the body's immunity by using controlled methods and means to activate the body's self-healing ability and to identify foreign harmful substances as well as damage factors and tumor cells that the body itself may produce while giving full play to individual initiative. With the continuous development of science, people could maintain and improve their immune system from many aspects, which could be roughly divided into nonpharmaceutical interventions and pharmaceutical interventions. Nonpharmacological interventions included changing lifestyles and habits, adjusting the nutritional structure and intake of food, regulating mindsets and emotions, and improving the living and working environment, etc. This review systematically elaborated on the functions and molecular mechanisms of nutrition, exercise, sleep, and emotion in regulating immunity, to provide some scientific evidence and theoretical support for proactive health.

Objective: To analyze the pattern and characteristics of occupational diseases in Weihai City from 2009 to 2020, and to provide scientific basis for the formulation of occupational disease prevention. Methods: In February 2021, retrospective analysis was performed on the cases of occupational diseases diagnosed from 2009 to 2020 in Weihai City. The relevant information and data were collected to analyze the types of occupational diseases, onset age, working age, diagnosis time, industry distribution, economic type and enterprise size distribution. Results: From 2009 to 2020, a total of 453 cases of new occupational diseases were reported in Weihai City. There were 431 males (95.14%) and 22 females (4.86%) . The average onset age was (49.16±8.51) years, and the average working age was (17.89±9.30) years. The incidence of pneumoconiosis and other respiratory diseases (322 cases, 71.08%) , occupational otolaryngology and oral diseases (71 cases, 15.67%) and occupational chemical poisoning (36 cases, 7.95%) were the top 3 cases, of which 313 cases were pneumoconiosis and 69 cases were noise deafness. The cases were mainly concentrated in the 40-59 years age group (357 cases, 78.81%) and the 10-19 years working age group (175 cases, 38.63%) . There were significant differences in the incidence of occupational diseases in different ages and different working ages (χ(2)=97.64, 80.74, P<0.001) . The new cases were mainly in mining industry (134 cases, 29.58%) , shipbuilding or maintenance industry (97 cases, 21.41%) , and private enterprises (350 cases, 77.26%) . Conclusion: Pneumoconiosis and noise deafness are the main emerging occupational diseases in Weihai City. Occupational disease prevention and control in private enterprises such as mining and shipbuilding or maintenance industry should be strengthened.

[A suspected case of delayed encephalopathy after acute hydrogen sulfide poisoning].

The main component of the gas in the fish storage tank is hydrogen sulfide. Hydrogen sulfide poisoning is a common occupational chemical poisoning among fishermen in summer, and acute hydrogen sulfide poisoning can manifest as toxic encephalopathy. This paper analyzes a patient with delayed encephalopathy suspected of acute hydrogen sulfide poisoning. The patient was unconscious for 18 days after waking up for 5 days after acute hydrogen sulfide poisoning. After waking up again, there were symptoms such as decreased limb muscle strength, ataxia, swallowing, dysarthria, and the clinical characteristics were significantly different from those of delayed encephalopathy caused by acute carbon monoxide poisoning, such as decreased cognitive function and damage to extrapyramidal system.

[FAT1 inhibits cell proliferation of esophageal squamous cell carcinoma through regulating the expression of CDK4/CDK6/CCND1 complex].

Objective: To explore the expression of FAT1 in esophageal squamous cell carcinoma (ESCC) tissues, and its effect on cell proliferation. Methods: The expression levels of FAT1 protein in human ESCC tissues and matched adjacent normal tissues were determined by immunohistochemistry (IHC). Lentivirus based knockdown of FAT1 was carried out in YSE2 and Colo680N cell lines and 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H tetrazolium bromide (MTT) assays was performed to examine the effect of FAT1 on the proliferation of these ESCC cells. Colony formation assay was used to detect the colony formation ability. Flow cytometry was performed to analyze the cell cycle and apoptosis. The expression levels of cell cycle markers in FAT1 knock out ESCC cell lines were detected by real-time quantitative reverse transcription polymerase chain reaction(qRT-PCR) and Western blot. Results: The relative expression of FAT1 in ESCC tissues was 66.97±21.53, significantly lower than 78.13±16.76 of adjacent normal tissues(P<0.05). Knockdown of FAT1 promoted cell proliferation and colony formation. In YSE2 cell, the division time in negative control (NC) group was (1 570±51) min, significantly longer than (1 356±31) min in shFAT1 group. In Colo680N cell, division time in NC group was (1 532±53) min, significantly longer than (1 290±30) min in shFAT1 group (P<0.05). Knockdown of FAT1 promoted G1-to S-phase transition and resulted in the upregulation of CDK4/CDK6/CCND1. Conclusion: FAT1 inhibits the proliferation and G1-to S-phase transition of ESCC cells through regulating the protein expression of CDK4/CDK6/CCND1 complex.

[Clinical manifestations analysis of patients diagnosed with primary pulmonary mucosa-associated lymphoid tissue lymphoma].

Objective: To analyze the clinical features of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: A total of 14 cases diagnosed with primary pulmonary MALT lymphoma were collected from May 2007 to May 2017 in Zhongshan Hospital, Fudan University. The clinical features, pathological characteristics, diagnosis, treatment and prognosis were retrospectively analyzed. Results: All 14 cases were pathologically diagnosed with primary pulmonary MALT lymphoma. The biopsy tissues were obtained through the Video-assisted Thoracoscopic Surgery (VATS) (4 cases), percutaneous puncture (2 cases), and bronchoscopy (8 cases). Cell types of these tumors were centrocyte-like cells (10 cases), lymphocytoid cells (2 cases), and monocytoid B cells (2 cases). The B cell clonality was detected by IgH cloning test in 4 cases and 3 of them were demonstrated with monoclonal strips. MALT1 breakup gene was positive in 3 out of 6 examined cases using fluorescence in situ hybridization (FISH). As for the treatment, 8 patients underwent chemotherapy, 5 patients underwent surgical resection and 1 patient abandoned treatment. Twelve patients were followed up to 9 years. The tumor recurrence occurred in 2 patients and resulted their death. Conclusions: The clinical manifestations of primary pulmonary MALT lymphoma are lack of specificity. The pathology, immunohistochemistry, IgH cloning test and MALT1 breakup gene tested by FISH are the criteria for diagnosis.

[Postoperative complications and survival analysis of 1 118 cases of open splenectomy and azygoportal disconnection in the treatment of portal hypertension].

Objective: To analyze the recent postoperative and long-term postoperative complications of open-splenectomy and disconnection in patients with portal hypertension. Methods: There were 1 118 cases with portal hypertension who underwent open splenectomy and azygoportal disconnection from April 2010 to September 2015 at Department of Surgery, People's Liberation Army 302 Hospital. Retrospective case investigation and telephone follow-up were conducted in October 2016. All patients had history of upper gastrointestinal bleeding before operation. Short-term complications after surgery were recorded including secondary laparotomy of postoperative abdominal hemostasis, severe infection, intake disorders, liver insufficiency, postoperative portal vein thrombosis and perioperative mortality. Long-term data including postoperative upper gastrointestinal rebleeding, postoperative survival rate and incidence of postoperative malignancy were recorded, too. GraphPad Prism 5 software for data survival analysis and charting. Results: Postoperative short-term complications in 1 118 patients included secondary laparotomy of postoperative abdominal hemostasis(1.8%, 21/1 118), severe infection(2.9%, 32/1 118), intake disorders(1.0%, 11/1 118), liver dysfunction (1.6%, 18/1 118), postoperative portal vein thrombosis(47.1%, 526/1 118)and perioperative mortality(0.5%, 5/1 118). After phone call following-up, 942 patients' long-term data were completed including 1, 3, 5 years postoperative upper gastrointestinal rebleeding rate(4.4%, 12.1%, 17.2%), 1, 3, 5-year postoperative survival rate(97.0%, 93.5%, 90.3%); the incidence of postoperative malignant tumors in 1, 3 and 5 years were 1.7%, 4.4% and 6.2%. Conclusions: Reasonable choosing of surgical indications and timing, proper performing the surgery process, effective conducting perioperative management of portal hypertension are directly related to the patient's short-term prognosis after portal hypertension. Surgical intervention can reduce the rates of patients with upper gastrointestinal rebleeding, improve survival, and do not increase the incidence of malignant tumors.

INSR gene polymorphisms correlate with sensitivity to platinum-based chemotherapy and prognosis in patients with epithelial ovarian cancer.

This study aimed to investigate the correlation between INSR gene polymorphisms on platinum-based chemotherapy sensitivity and prognosis in epithelial ovarian cancer (EOC). A total of 339 EOC patients receiving postoperative chemotherapy were recruited for the study. Tag single-nucleotide polymorphism of INSR gene was screened from HapMap combined with available literature. Frequency distribution of genotypes and alleles in INSR gene was sequenced by ABI3100-Avant. Compared with CC+GC genotype, INSR rs2252673 GG genotype and rs3745546 CC genotype showed less platinum-based chemotherapy sensitivity in EOC patients (odds ratio (OR)=0.269, 95% confidence interval (CI)=0.159~0.456; OR=0.445, 95% CI=0.214~0.926, respectively), as well as serous EOC patients (OR=0.083, 95% CI=0.024~0.278; OR=0.235, 95%CI=0.053~1.041, respectively). The clinical characteristics including age, clinical stage, histological grade and residual lesion size were significantly related with chemosensitivity to platinum drugs and mortality in EOC patients. According to Kaplan-Meier curve, compared with CC+GC genotype, rs2252673 GG genotype showed significantly decreased survival rate in EOC patients (P<0.05). Cox regression model indicated that rs2252673, age and clinical stage were independent risk factors for the prognosis in EOC (all P<0.05). These findings indicate that INSR rs2252673 and rs3745546 polymorphisms were associated with sensitivity to platinum-based chemotherapy in EOC patients and rs2252673 polymorphism may be an independent risk factor for EOC prognosis.

Plasmonic reflection color filters with metallic random nanostructures.

We develop reflective color filters with randomly distributed nanodisks and nanoholes fabricated with hydrogen silsesquioxane and Ag films on silicon substrate. They exhibit high resolution, angle-independence and easily up-scalable fabrication, which are the most important factors for color filters for industrial applications. We uncover the underlying mechanism after systematically analyzing the localized surface plasmon polariton coupling in the electric-field distribution. The agreement of the experimental results with those from the simulation indicates that tunable colors across the visible spectrum can be obtained by simply varying the diameter of the nanodisks, promoting their applications.

Emerging of canine kobuvirus in dogs in China, 2015.

Canine kobuvirus (CaKoV) is a newly emerging virus in dogs, which relates to the diarrhea of dogs. To investigate the CaKoV infection in dog population, fecal samples of dogs were collected from three provinces of China in 2015. The results of genetic analysis based on the complete VP1 gene showed that six CaKoVs isolates in this study were closely related with the Chinese canine originated isolate CH1 (90.6%-91.9% nucleotide identities). The phylogenetic analysis demonstrated that the Chinese isolates clustered into a unique branch compared with isolates from other countries. The present study suggested that the CaKoVs had established infection in Chinese dog population. The systematic epidemiological investigation should be further carried out to evaluate the prevalence of the CaKoV infection in China.

[Etiological analysis and establishment of a discriminant model for lower respiratory tract infections in hospitalized patients].

Objective: To analyze the pathogens of lower respiratory tract infection(LRTI) including bacterial, viral and mixed infection, and to establish a discriminant model based on clinical features in order to predict the pathogens. Methods: A total of 243 hospitalized patients with lower respiratory tract infections were enrolled in Fujian Provincial Hospital from April 2012 to September 2015. The clinical data and airway (sputum and/or bronchoalveolar lavage) samples were collected. Microbes were identified by traditional culture (for bacteria), loop-mediated isothermal amplification(LAMP) and gene sequencing (for bacteria and atypical pathogen), or Real-time quantitative polymerase chain reaction (Real-time PCR)for viruses. Finally, a discriminant model was established by using the discriminant analysis methods to help to predict bacterial, viral and mixed infections. Results: Pathogens were detected in 53.9% (131/243) of the 243 cases.Bacteria accounted for 23.5%(57/243, of which 17 cases with the virus, 1 case with Mycoplasma pneumoniae and virus), mainly Pseudomonas Aeruginosa and Klebsiella Pneumonia. Atypical pathogens for 4.9% (12/243, of which 3 cases with the virus, 1 case of bacteria and viruses), all were mycoplasma pneumonia. Viruses for 34.6% (84/243, of which 17 cases of bacteria, 3 cases with Mycoplasma pneumoniae, 1 case with Mycoplasma pneumoniae and bacteria) of the cases, mainly Influenza A virus and Human Cytomegalovirus, and other virus like adenovirus, human parainfluenza virus, respiratory syncytial virus, human metapneumovirus, human boca virus were also detected fewly. Seven parameters including mental status, using antibiotics prior to admission, complications, abnormal breath sounds, neutrophil alkaline phosphatase (NAP) score, pneumonia severity index (PSI) score and CRUB-65 score were enrolled after univariate analysis, and discriminant analysis was used to establish the discriminant model by applying the identified pathogens as the dependent variable. The total positive predictive value was 64.7%(77/119), with 66.7% for bacterial infection, 78.0% for viral infection and 33.3% for the mixed infection. Conclusions: The mostly detected pathogens were Pseudomonas aeruginosa, atypitcal pathogens, Klebsiella pneumoniae, influenza A virus and human cytomegalovirus in hospitalized patients with LRTI in this hospital. The discriminant diagnostic model established by clinical features may contribute to predict the pathogens of LRTI.

Polarization-independent plasmonic subtractive color filtering in ultrathin Ag nanodisks with high transmission.

We demonstrate a TE/TM polarization-independent plasmonic subtractive color filtering scheme employing ultrathin two-dimensional Ag nanodisks. These TE/TM polarization-independent subtractive color filters exhibit small feature sizes (below 200 nm) and high transmission up to 70% in the visible spectral region, superior to previously reported plasmonic color filters. Simulated optical transmission spectra and colors are in good agreement with experimental results. The color-filtering behaviors strongly depend on thickness and period of nanodisks. Underlying mechanisms are also discussed in detail.

Methods of preservation and flotation for the detection of nematode eggs and coccidian oocysts in faeces of the forest musk deer.

Parasitic infections influence the health of captive forest musk deer (Moschus berezovskii) and affect population increases. Nevertheless, there are few quantitative studies regarding forest musk deer parasites, and there is no common preservation method or flotation solution used for detection of faecal parasites because of the biology of the worms and the host physiological state. The objective of this study was to evaluate preservation and flotation methods for the detection of nematode eggs and coccidian oocysts in faeces of the forest musk deer. The McMaster technique was used to count nematode eggs and coccidian oocysts in 33 samples of faeces. For the nematode eggs, the differences among flotation solutions were significant (P< 0.01), with sodium nitrate being the best flotation solution, and the combination of freezing and sodium nitrate resulted in the greatest number of eggs per gram (EPG = 209.4 ± 67.8). For the coccidian oocysts, the interaction between preservation method and flotation solution was significant (P< 0.01), and the combination of formalin and sodium chloride yielded the greatest number of oocysts per gram (OPG = 1010.7 ± 162.3). The forest musk deer had a high prevalence of parasitic infections, with the parasite load of coccidia (96.4%) significantly greater than that of nematodes (71.9%, P< 0.01). These results confirm that captive forest musk deer suffer from serious parasitic invasions and demonstrate that the novel method described here could be utilized for parasitological diagnosis, detection and prevention in species of Moschidae and Cervidae.

Effect of relative nanohole position on colour purity of ultrathin plasmonic subtractive colour filters.

Plasmonic subtractive color filters through patterning periodic nanostructures on ultrathin Ag films deposited on a glass substrate, exhibiting good durability, simple fabrication, and flexible color tunability, have attracted considerable attention due to their tremendous potential applications. While previous studies have mainly focused on their extraordinary physical mechanisms, color purity, which is another key parameter for high quality imaging applications, has been much less investigated. In this work, we demonstrate that the relative position of nanoholes patterned on ultrathin Ag films can largely affect the color purity of plasmonic subtractive color filters. The calculated results agree reasonably well with the experimental data, revealing that the purity of subtractive colors can be improved by changing the nanohole arrays from square lattice to triangular lattice without reducing transmission at visible frequencies. In addition, underlying mechanisms are clarified by systematically analyzing the dominant valley in transmission spectra.

Construction of a natural phage antibody library of human anaplastic thyroid carcinoma.

The objective of this study was to identify and construct a human natural phage single-chain antibody (scFv) library of human anaplastic thyroid carcinoma (ATC) using phage display technology. Total RNA was extracted from lymphatic tissue near an ATC and used to amplify variable heavy chain (VH) and variable light chain (VL) fragments with added linker sequences using reverse transcription-polymerase chain reaction (RT-PCR). After purification, the VH and VL amplicons were used to produce scFv fragments with added SfiI and NotI restriction enzyme recognition sites using splicing-overlap-extension PCR. Following digestion, the scFv gene was cloned in the pCANTAB-5E plasmid, and the recombinant phagemids were transformed into the susceptible Escherichia coli TG1 strain. After infection by the helper phage M13K07, a human ATC phage antibody library was successfully constructed. Clear 28 S and 18 S bands could be seen in the total RNA from the library, and the sizes of the VH, VL, and scFv genes contained therein were approximately 370, 350, and 750 bp, respectively. In addition, the conversion efficiency as measured by the pUC19 standard plasmid was 10(8) CFU/µg, and the positive insert ratio was 86.4% (19/22). These results demonstrated the successful construction of a human ATC scFv antibody gene library, and might provide the experimental basis for the further screening and identification of a phage single-chain antibody with ATC cell-specificity.

[A prospective randomized controlled study on the repair of skin and soft tissue defect in functional areas of children with full-thickness skin grafts from different sites of abdomen].

Objective: To compare and analyze the effect of repairing small skin and soft tissue defect wounds in functional areas of children with full-thickness skin grafts from different sites of abdomen. Methods: A prospective randomized controlled study was conducted. From January 2019 to June 2020, 60 female children with small skin and soft tissue defects in functional areas requiring full-thickness skin grafting, who met the inclusion criteria, were admitted to the First Affiliated Hospital of Air Force Medical University. According to the random number table, the children were divided into two groups, with 28 cases left in lateral abdomen group aged 5 (3, 8) years and 29 cases in lower abdomen group aged 5 (3, 7) years after the exclusion of several dropped-out children in follow-up. In lower abdomen group, 20 (12, 26) cm2 wounds of children were repaired with (24±10) cm2 full-thickness skin graft from transverse skin lines in the inferior abdomen area, while in lateral abdomen group, 23 (16, 32) cm2 wounds of children were repaired with (24±9) cm2 full-thickness skin graft from below the umbilical plane to above the groin in the lateral abdomen area. All the children were treated with continuous intradermal suture at the donor site incision and received continuous negative pressure treatment of -10.64 to -6.65 kPa in the donor and recipient areas after operation. The donor site was treated with a medical skin tension-reducing closure device since post-surgery day (PSD) 7. The use of medical skin tension-reducing closure device at the donor site, postoperative complications and suture removal time of the donor area were recorded, and the incidence of complications was calculated. On PSD 7, a self-designed efficacy satisfaction questionnaire was used to investigate the parents' satisfaction with the curative effect of their children. In post-surgery month (PSM) 1 and 6, Vancouver scar scale (VSS) was used to evaluate the scar at the donor site, and the VSS score difference between the two time points was calculated; the scar width at the donor site was measured with a ruler, and the scar width difference between the two time points was calculated. Data were statistically analyzed with independent sample t test or Cochran & Cox approximate t test, Mann-Whitney U test, and Fisher's exact probability test. Results: The proportion of children in lateral abdomen group who used the medical skin tension-reducing closure device in the donor area for equal to or more than 4 weeks after surgery was significantly higher than that in lower abdomen group (P<0.05). On PSD 7, there was one case of partial incision dehiscence in the donor area, one case of peripheral skin redness and swelling in the donor area, and one case of fat liquefaction in the donor area in lateral abdomen group, and one case of partial incision dehiscence in the donor area in lower abdomen group. The incidence of postoperative complications at the donor site of children in lower abdomen group was significantly lower than that in lateral abdomen group (P<0.05). Compared with that in lateral abdomen group, the suture removal time at the donor site of children after surgery in lower abdomen group was significantly shorter (t'=17.23, P<0.01). On PSD 7, the satisfaction score of parents with the curative effect of their children in lower abdomen group was significantly higher than that in lateral abdomen group (t'=20.14, P<0.01). In PSM 1 and 6, the VSS scores of scar at the donor site of children in lower abdomen group were 2.7±0.9 and 2.8±1.0, respectively, which were significantly lower than 7.1±2.2 and 9.1±2.7 in lateral abdomen group (with t values of 10.00 and 11.15, respectively, P<0.01). In PSM 6, the VSS score of scar at the donor site of children in lateral abdomen group was significantly higher than that in PSM 1 (t=3.10, P<0.01), while the VSS score of scar at the donor site of children in lower abdomen group was not significantly higher than that in PSM 1 (P>0.05). The VSS score difference of scar at the donor site of children in lateral abdomen group was significantly greater than that in lower abdomen group (Z=-8.12, P<0.01). In PSM 1 and 6, the scar widths at the donor site of children in lower abdomen group were 2.0 (1.0, 2.0) and 2.0 (2.0, 3.0) mm, respectively, which were significantly narrower than 6.0 (4.0, 10.0) and 8.5 (5.0, 12.0) mm in lateral abdomen group (with Z values of -13.41 and -14.70, respectively, P<0.01). In PSM 6, the scar width at the donor site of children in lateral abdomen group was significantly wider than that in PSM 1 (Z=-2.79, P<0.01), while the scar width at the donor site of children in lower abdomen group was not significantly wider than that in PSM 1 (P>0.05). The difference of scar width at the donor site of children in lateral abdomen group was significantly greater than that in lower abdomen group (Z=-14.93, P<0.01). Conclusions: The use of full-thickness skin grafts from the lower abdomen to repair small skin and soft tissue defect wounds in functional areas of children, especially girls, is effective, simple and easy to operate, and conforms to the principle of aesthetic repair. Compared with transplantation with full-thickness skin graft from the lateral abdomen, lower abdominal full-thickness skin grafting has a low incidence of donor site complications and no obvious scar hyperplasia, which is worthy of clinical promotion.

Clinical efficacy of targeted therapy, immunotherapy combined with hepatic artery infusion chemotherapy (FOLFOX), and lipiodol embolization in the treatment of unresectable hepatocarcinoma.

To evaluate the clinical efficacy of targeted therapy and immunotherapy combined with hepatic arterial infusion chemotherapy (HAIC) of FOLFOX and lipiodol embolization in the treatment of unresectable hepatocellular carcinoma. Patients included in the study were those who received targeted therapy and immunotherapy combined with HAIC of FOLFOX and lipiodol embolization in Zhongshan People's Hospital from December 2020 to June 2021 for unresectable hepatocellular carcinoma. Evaluation indicators included objective response rate (ORR), median progression-free survival (mPFS), median duration of response (mDOR), 1-year overall survival rate (OS), surgical conversion rate, and adverse events. Treatment response was assessed using Response Evaluation Criteria in Solid Tumors (mRECIST and RECIST v1.1). A total of 35 patients were included in this study, 30 of whom completed treatment evaluation. According to mRECIST evaluation criteria, the objective response rate (ORR) was 83.3% (25/30); the complete response (CR) was 60% (18/30); the partial response (PR) was 23.3% (7/30), and stable disease (SD) was 16.7% (5/30). The mDOR was 10.3 months (95% Cl: 8.27-NE), and the mPFS was 13.2 months (95% CI: 10.3-NE); the surgical conversion rate was 30.0% (9/30). The 1-year OS was 96.7%. There were no serious surgical complications and grade 4 or 5 adverse events of targeted therapy, immunotherapy and HAIC. Some patients had grade 3 adverse reactions in gastrointestinal toxicity or hepatotoxicity, and the adverse reactions were improved after corresponding symptomatic treatment. We concluded that HAIC of FOLFOX and lipiodol embolization combined with targeted therapy and immunotherapy had a significant curative effect in the treatment of unresectable hepatocellular carcinoma, with no serious adverse reactions and a high rate of surgical conversion rate.
