Abstract
Sensing of benzene vapor is a hot spot due to the volatile drastic carcinogen even at trace concentration. However, achieving convenient and rapid detection is still a challenge. As a sort of functional porous material, metal-organic frameworks (MOFs) have been developed as detection sensors by adsorbing benzene vapor and converting it into other signals (fluorescence intensity/wavelength, chemiresistive, weight or color, etc.). Supramolecular interaction between benzene molecules and the host framework, aperture size/shape and structural flexibility are influential factors in the performance of MOF-based sensors. Therefore, enhancing the host-guest interactions between the host framework and benzene molecules, or regulating the diffusion rate of benzene molecules by changing the aperture size/shape and flexibility of the host framework to enhance the detection signal are effective strategies for constructing MOF-based sensors. This concept highlights several types of MOF-based sensors for the detection of benzene vapor.

Abstract
Objective: To analyze the clinical data of acute copper sulphate poisoning, and discuss the timing and prognosis of the treatment. Methods: The clinical data of a case of acute copper sulphate poisoning treated in Yantaishan Hospital in May 2020 were analyzed, and CNKI, Weipu database and Wanfang database were retrieved with "copper sulfate""poisoning" and "blood purification" as search terms respectively. Such as "copper sulphate/cupric sulfate""poisoning" and "blood purification " were respectively tested in the PubMed database and reviewed the literatures. Results: The patient was admitted to hospital due to "oral copper pentahydrate for 14 h". Plasma exchange and continuous venous hemofiltration were performed on the 2nd day of poisoning, and the liver enzymes and creatinine indexes were normal. The patient recovered and left the hospital after 10 days. After literature retrieval, 13 literatures were screened out, a total of 14 cases were reported. All recovered after blood purification, copper displacement and liver protection. Conclusion: When acute copper sulphate poisoning occurs with multiple organ function damage mainly caused by hemolysis and kidney injury, the treatment with blood purification has a good prognosis while removing copper and organ support.

Abstract
Objective: To analyze the incidence characteristics of occupational chronic benzene poisoning under two diagnostic criteria. Methods: In March 2020, 126 patients who were divided into the old criteria group (74 cases) and the new criteria group (52 cases) were retrospectively analyzed. These patients were diagnosed with occupational chronic benzene poisoning, and were diagnosed in our hospital during the period of January 2009 to December 2019. The gender composition, age of onset, years of benzene exposure, industry distribution, work type, benzene concentration in working environment and diagnostic grade of the two groups of patients were analyzed and compared. The follow-up of 22 benzene poisoning observation subjects under the old criteria were retrospectively analyzed. Results: There were no statistically significant differences in gender composition, age of onset, years of benzene exposure, industry distribution and work type between the old criteria group and the new criteria group (P>0.05) . In the old criteria group and the new criteria group, 41.9% (31/74) and 17.3% (9/52) of the patients' workplace benzene concentration exceeded the maximum allowable concentration, respectively. The composition of different benzene concentration in the workplace between the two groups showed statistically significant (P<0.05) . In the old criteria group, the proportion of mild poisoning (79.7%, 59/74) was the majority, while in the new criteria group, the proportion of moderate and severe poisoning (51.9%, 27/52) were the majority, and there was statistically significance in the composition ratio of diagnostic grade between the two groups (P<0.05) . Under the old criteria, after folow-up of 22 cases of benzene poisoning observation subjects, we observed that 8 cases (36.4%) progressed to the level of chronic benzene poisoning. Conclusion: The revision of diagnostic criteria for benzene poisoning may affect the composition of diagnosis classification. Based on the rights and interests of workers, formulating more complete diagnostic criteria and system policies will be more conducive to the development of occupational benzene poisoning prevention and control.

Abstract
Objective: To study the clinical efficacy of sequential glucocorticoids in the treatment of acute mercury poisoning complicated with interstitial pneumonia. Methods: Retrospective analysis of 37 patients with acute mercury poisoning complicated with interstitial pneumonia admitted from January 2009 to April 2019, including the sequential treatment group (15 cases) and the conventional treatment group (22 cases) , all patients were treated with sodium dimercaptopropane sulfonate, and given anti-inflammatory, liver-protecting and other drugs for symptomatic treatment. The conventional treatment group was given methylprednisolone 1mg/kg once a day for 5-7 days. The sequential treatment group was given 1 mg/kg of methylprednisolone once a day for 5-7 days, then gradually reduced to 20 mg, and the total course of treatment was 14-21 days. To observe the changes of clinical symptoms, signs, lung function including forced vital capacity (FVC) , forced expiratory volume in the first second (FEV(1)) and ratio of forced expiratory volume in the first second to forced vital capacity (FEV(1)/FVC) , and chest CT indexes before and after treatment in the two groups. Results: The clinical symptoms and signs of the two groups were significantly improved compared with those before treatment, and there was no significant difference between the apparent efficiency and the total effective rate of the two groups (P>0.05) . The FVC, FEV(1), and FEV(1)/FVC of the two groups were significantly higher than those before treatment. After treatment, the indexes of the sequential treatment group were significantly higher than that of the conventional treatment group, and the difference was statistically significant (P<0.05) . The apparent efficiency (93.3%, 14/15) of CT lesions in the sequential treatment group was significantly higher than those of the conventional treatment group (59.1%, 13/22) , and the difference was statistically significant (P< 0.05) . Conclusion: Sequential glucocorticoid treatment of acute mercury poisoning complicated with interstitial pneumonia could improve the effect of clinical signs and symptoms which is equal to conventional treatment, but it could better promote the recovery of lung function and the absorption of lung lesions.

Abstract
Objective: To evaluate the role of histologicalpathology in the diagnosis of periprosthetic joint infection. Methods: A total of 145 cases of joint arthroplasty during October 2017 and October 2018 from Beijing Jishuitan Hospital were collected. There were 23 cases of infection, including knee joint arthroplasty (12 cases) and hip arthroplasty (11 cases). There were 17 females and 6 males. Patients' age ranged from 39 to 76 years (mean 63 years). The infection was diagnosed if there were >5 neutrophils per high power field in at least 5 high power field. The permanent sections were examined twice separately by two pathologists, and the interval time of histologic examination was at least two weeks. Sensitivity (SE), specificity (SP), positive predictivevalue (PPV), and negative predictive value (NPV) were calculated. The consistency evaluation of histologic examination of two pathologists was calculated by Kappa analysis. Results: The neutrophil cells could locate scattered or focally in the synovium tissue of periprosthetic joint infection. Somewhere, the infiltration of vessel and the perivascular distribution could also exist. Opportunity coincidence rate between two pathologists was 91.3% (Kappa=0.817). The results showed that SE was 60.9%, SP was 100.0%, NPV was 93.1%, PPV was 100.0%. Conclusions: The presence of polymorphonuclear cells in histologic examination is correlated with infection. There was high consistency between histologic examination and clinical diagnosis of joint arthroplasty.

Abstract
Objective: To analyze the clinicopathological features of pseudotumor-like tissue around aseptic joint arthroplasty and aseptic lymphocytic vasculitis-associated lesions (ALVAL) scores. The characters of wear granules were observed. Methods: Total 122 cases were retrieved from the surgical pathology files between May 2015 and August 2018 in the department of pathology in Beijing Jishuitan Hospital, which included the knee joint arthroplasty (10 cases) and hip arthroplasty (112 cases). There were 62 females and 60 males. Patients' age ranged from 29 to 86 years (mean 56 years). The pseudotumor-like tissue around aseptic joint arthroplasty were stained with HE and analyzed by two ALVAL score systems. The characters of wear granules were observed by light microscope and polarized light. Results: The cohort included 62 females and 60 males. Patients' age ranged from 29 to 86 years (mean 56 years). Compbell-ALVAL system includes synovial lining,inflammatory infiltrate and tissue organization. The scores were: low (0-4): 18cases; moderate (5-8): 101 cases; high (9-10): 3 cases. Oxford-ALVAL system only evaluated the inflammatory infiltrate,and the scores were:0 grade:56 cases; 1 grade:51 cases; 2 grade: 12 cases; 3 grade:3 cases. Cases with high score in the Compbell-ALVAL system were concordant with the 3 grade of the Oxford-ALVAL system. Under light microscope,the metal particles were small black granules; the polyethylene fibers were needle-like and easily visible in polarized light. The polymethylmethacrylate showed clear spaces because of particle melting. Conclusions: The Compbell-ALVAL scoring system is based on the histologic analysis of pseudotumor-like tissue around aseptic joint arthroplasty, and the Oxford-ALVAL scoring systems is based on lymphocytic response. The wear particles could be differentiated by the features in the light microscope.
