RESUMEN
The global diversity of fungi has been estimated between 2 to 11 million species, of which only about 155 000 have been named. Most fungi are invisible to the unaided eye, but they represent a major component of biodiversity on our planet, and play essential ecological roles, supporting life as we know it. Although approximately 20 000 fungal genera are presently recognised, the ecology of most remains undetermined. Despite all this diversity, the mycological community actively researches some fungal genera more commonly than others. This poses an interesting question: why have some fungal genera impacted mycology and related fields more than others? To address this issue, we conducted a bibliometric analysis to identify the top 100 most cited fungal genera. A thorough database search of the Web of Science, Google Scholar, and PubMed was performed to establish which genera are most cited. The most cited 10 genera are Saccharomyces, Candida, Aspergillus, Fusarium, Penicillium, Trichoderma, Botrytis, Pichia, Cryptococcus and Alternaria. Case studies are presented for the 100 most cited genera with general background, notes on their ecology and economic significance and important research advances. This paper provides a historic overview of scientific research of these genera and the prospect for further research.

RESUMEN
Objective: To investigate the mechanism of interleukin-6 (IL-6) /signal transducers and activators of transcriptional 3 (STAT3) /helper T cell 17 (Th17) signaling pathway in lung injury of rats with sepsis intervened by forsythia, with a view to provide experimental basis for the role and mechanism of forsythia in the treatment of sepsis. Methods: In July 2021, 30 healthy Wistar male rats were selected and randomly divided into sham operation group, model group and treatment group, with 10 rats in each group. The rat model of sepsis was established by cecal ligation and puncture. 2 h after recovery, the rats were given traditional Chinese medicine forsythia orally, twice a day at an interval of 12 h. The wet/dry mass ratio (W/D) of lung tissue was detected 24 h after surgery. The morphological changes of lung tissue were detected by HE staining. Flow cytometry was used to detect Th17 population in peripheral blood. The expression levels of IL-6 and interleukin-17A (IL-17A) in serum were determined by enzyme-linked immunosorbent assay. The mRNA expression levels of IL-17A and IL-6 in lung tissues were detected by reverse transcription-polymerase chain reaction. The expression levels of STAT3 and IL-17A in lung tissue were determined by Western blotting. Results: Compared with model group, the W/D of lung tissue in treatment group was decreased, and the difference was statistically significant (P<0.05). HE staining of lung tissue showed that compared with the model group, the degree of lung lesion and injury was reduced in the treatment group. Compared with sham operation group, the proportion of Th17 cells in CD4 lymphocytes in peripheral blood of rats in model group was significantly increased (P<0.05). Compared with model group, the proportion of Th17 cells in CD4 lymphocytes in peripheral blood of rats in treatment group was significantly decreased (P<0.05). Compared with sham operation group, peripheral blood serum IL-6 and IL-17 of rats in model group were significantly increased (P<0.05). Compared with model group, IL-6 and IL-17 in peripheral blood serum of rats in treatment group were decreased (P<0.05). Compared with sham operation group, the expressions of IL-17A and IL-6 mRNA in lung tissue of model group were significantly increased (P<0.05). Compared with model group, the expressions of IL-17A and IL-6 mRNA in lung tissue of rats in treatment group were significantly decreased (P<0.05). Compared with sham operation group, the protein expressions of STAT3 and IL-17A in lung tissue in model group were significantly increased (P<0.05). Compared with model group, the pritein expressions of STAT3 and IL-17A in lung tissue in treatment group were significantly decreased (P<0.05) . Conclusion: Forsythia plays a role in alleviating lung injury by down-regulating the expressions of the signaling pathway IL-6/STAT3/Th17, which providing a new target for the treatment of sepsis induced lung injury.

Brucellosis can lead to pathological changes of multiple systems. Capillary leak syndrome (CLS) is a clinical syndrome caused by different reasons, mainly characterized by hypotension, hypoproteinemia and systemic edema. The condition is critical and the clinical manifestations are complex, and multiple organ dysfunction syndrome (MODS) may occur in severe cases. CLS caused by brucellosis is extremely rare. The diagnosis and treatment of a patient with brucellosis complicated with CLS and MODS was analyzed in this paper, in order to improve the knowledge of clinicians about brucellosis and its complications.

The current study analyzed the mutation rate of BRAFV600E in papillary thyroid carcinoma patients and the correlation between BRAFV600E mutation and aggressive biological behavior of papillary thyroid carcinoma. A total of 160 patients with papillary thyroid carcinoma who underwent surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from October 2020 to November 2021 were retrospectively included. All patients underwent BRAFV600E gene detection. There were 37 males and 123 females, with a mean age of (46.5±11.1) years. The mutation rate of BRAFV600E was 86.3% (138/160). There was no significant correlation between the mutation of BRAFV600E and aggressive factors such as age (P=0.917), single focal/multifocal tumor (P=0.673), tumor size (P=0.360), tumor invasion (P=0.150) and regional lymph node metastasis (P=0.406). Therefore, for papillary thyroid cancer, mutations in a single gene like BRAFV600E fail to determine more active diagnosis and treatment.

We studied the effect of fibroblast growth factor receptor 3 (FGFR3) inhibitor BGJ-398 on the differentiation of bone marrow mesenchymal stem cells (BM MSC) into osteoblasts in wild type (wt) mice and in animals with mutation in TBXT gene (mt) and possible differences in the pluripotency of these cells. Cytology tests showed that the cultured BM MSC could differentiate into osteoblasts and adipocytes. The effect of different BGJ-398 concentrations on the expression of FGFR3, RUNX2, SMAD1, SMAD4, SMAD5, SMAD6, SMAD7, and SMAD8 were studied by quantitative reverse transcription PCR. The expression of RUNX2 protein was evaluated by Western blotting. BM MSC of mt and wt mice did not differ in pluripotency and expressed the same membrane marker antigens. BGJ-398 inhibitor reduced the expression of FGFR3 and RUNX2. In BM MSC from mt and wt mice have similar gene expression (and its changing) in FGFR3, RUNX2, SMAD1, SMAD4, SMAD5, SMAD6, SMAD7, and SMAD8 genes. Thus, our experiments confirmed the effect of decreased expression of FGFR3 on osteogenic differentiation of BM MSC from wt and mt mice. However, BM MSC from mt and wt mice did not differ in pluripotency and are an adequate model for laboratory research.

Objective: To investigate the therapeutic effect and mechanism of Liangge Powder against sepsis-induced acute lung injury (ALI) . Methods: From April to December 2021, the key components of Liangge Powder and its targets against sepsis-induced ALI were analyzed by network pharmacology, and to enrich for relevant signaling pathways. A total of 90 male Sprague-Dawley rats were randomly assigned to sham-operated group, sepsis-induced ALI model group (model group), Liangge Powder low, medium and high dose group, ten rats in the sham-operated group and 20 rats in each of the remaining four groups. Sepsis-induced ALI model was established by cecal ligation and puncture. Sham-operated group: gavage with 2 ml saline and no surgical treatment. Model group: surgery was performed and 2 ml saline was gavaged. Liangge Powder low, medium and high dose groups: surgery and gavage of Liangge Powder 3.9, 7.8 and 15.6 g/kg, respectively. To measure the wet/dry mass ratio of rats lung tissue and evaluate the permeability of alveolar capillary barrier. Lung tissue were stained with hematoxylin and eosin for histomorphological analysis. The levels of tumor necrosis factor-alpha (TNF-α), interleukin (IL) -6 and IL-1ß in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay. The relative protein expression levels of p-phosphatidylinositol 3-kinase (PI3K), p-protein kinase B (AKT), and p-ertracellular regulated protein kinases (ERK) were detected via Western blot analysis. Results: Network pharmacology analysis indicated that 177 active compounds of Liangge Powder were selected. A total of 88 potential targets of Liangge Powder on sepsis-induced ALI were identified. 354 GO terms of Liangge Powder on sepsis-induced ALI and 108 pathways were identified using GO and KEGG analysis. PI3K/AKT signaling pathway was recognized to play an important role for Liangge Powder against sepsis-induced ALI. Compared with the sham-operated group, the lung tissue wet/dry weight ratio of rats in the model group (6.35±0.95) was increased (P<0.001). HE staining showed the destruction of normal structure of lung tissue. The levels of IL-6 [ (392.36±66.83) pg/ml], IL-1ß [ (137.11±26.83) pg/ml] and TNF-α [ (238.34±59.36) pg/ml] were increased in the BALF (P<0.001, =0.001, <0.001), and the expression levels of p-PI3K, p-AKT and p-ERK1/2 proteins (1.04±0.15, 0.51±0.04, 2.31±0.41) were increased in lung tissue (P=0.002, 0.003, 0.005). The lung histopathological changes were reduced in each dose group of Liangge Powder compared with the model group. Compared with the model group, the wet/dry weight ratio of lung tissue (4.29±1.26) was reduced in the Liangge Powder medium dose group (P=0.019). TNF-α level [ (147.85±39.05) pg/ml] was reduced (P=0.022), and the relative protein expression levels of p-PI3K (0.37±0.18) and p-ERK1/2 (1.36±0.07) were reduced (P=0.008, 0.017). The wet/dry weight ratio of lung tissue (4.16±0.66) was reduced in the high-dose group (P=0.003). Levels of IL-6, IL-1ß and TNF-α[ (187.98±53.28) pg/ml, (92.45±25.39) pg/ml, (129.77±55.94) pg/ml] were reduced (P=0.001, 0.027, 0.018), and relative protein expression levels of p-PI3K, p-AKT and p-ERK1/2 (0.65±0.05, 0.31±0.08, 1.30±0.12) were reduced (P=0.013, 0.018, 0.015) . Conclusion: Liangge Powder has therapeutic effects in rats with sepsis-induced ALI, and the mechanism may be related to the inhibition of ERK1/2 and PI3K/AKT pathway activation in lung tissue.

Objective: To investigate the application of retroauricular groove incision in the resection of benign tumors in the deep lobe of parotid. Methods: From January 2017 to January 2022, 19 patients (11 males and 8 females, age ranged from 17 to 69 years, with a median age of 48) with benign tumor in the deep lobe of parotid gland underwent parotidectomy through retroauricular sulcus incision in Linyi People's Hospital. Among them, 17 cases with tumor diameter≤4.0 cm underwent simple retroauricular groove incision, and 2 cases were dumbbell type with tumor diameter>4.0 cm on the medial side of mandible protruding into the parapharyngeal space, in which the deep lobe and tumor of parotid gland were resected through retroauricular sulcus incision combined with intraoral incision. Results: Tumors were completely removed through retroauricular sulcus incision in 17 cases, and dumbbell type tumors were removed through retroauricular sulcus incision combined with intraoral incision in 2 cases. Postoperative pathological examinations showed pleomorphic adenoma in 13 cases, basal cell adenoma in 4 cases and Warthin's tumor in 2 cases. Temporary mandibular marginal branch paralysis occurred in 2 patients and returned to normal 3 weeks after operation. All incisions healed in Phase I. By following-up of 1-5 years with a median follow-up time of 3.1 years, none of the patients had Frey syndrome, salivary fistula, other complications and tumor recurrence. The patients and their families were satisfied with the postoperative facial appearances. Conclusion: The retroauricular groove approach can not only preserve the function of parotid superficial lobe and facial nerve, but also has less trauma, less tissue defect and hidden scar. As the advantages of less complication, low recurrence rate and good cosmetic effect, the incision is worthy of clinical application.

Objective: To explore the action mechanism of hsa_circ_0000231 in the occurrence and development of tongue squamous cell carcinoma (TSCC). Methods: Tissue samples of 60 TSCC patients were examined. The patients, including 32 males and 28 females, aged from 36 to 84 years old, underwent surgery in the Affiliated Hospital of Nantong University and Affiliated Tumor Hospital of Nantong University from December 2014 to December 2017. Saliva samples were obtained from healthy volunteers (5 males and 5 females, aged from 40 to 75 years old) and 10 TSCC patients. The TSCC cell lines (CAL-27, Tca-8113 and HN-4) were used. The expression levels of hsa_circ_0000231 in 60 pairs of freshly matched TSCC and para-carcinoma tissue samples, 10 pairs of saliva samples and 3 TSCC cell lines were detected by quantitative real-time polymerase chain reaction (qRT-PCR). hsa_circ_0000231 gene interference and lentiviral transfection were constructed, hsa_circ_0000231 in TSCC cell lines CAL-27 and Tca-8113 was knocked down, and the expressions of hsa_circ_0000231 in hsa_circ_0000231 interference group (sh-circ) and no-load lentivirus group (negative control) were tested with qRT-PCR. Cells with the highest knock-down efficiency were selected for CCK-8 test, colony formation assay, transwell invasion assay and scratch assay. The expressions of EMT-related proteins including E-cadherin, snail protein, N-cadherin and vimentin and proteins related to Wnt/ß-catenin signaling pathway including ß-catenin, C-myc, Bcl-2, MMP-9 and Cyclin D1 were measured by western blot. After TSCC cells in the interference group were co-cultured with Wnt/ß-catenin pathway activator LiCl, the expressions of above proteins were re-measured by western blot. TSCC cells in interference group and control group were subcutaneously injected into nude mice to compare the effect of hsa_circ_0000231 knockdown on the growths of the tumors grafted subcutaneously in the nude mice. Statistical analysis software 25.0 was used for data analysis, and t-test or chi-square test was used for comparison between groups. Results: hsa_circ_0000231 was highly expressed in the tissue and saliva samples of TSCC patients and cell lines CAL-27, Tca-8113 and HN-4, but lowly expressed in paired para-carcinoma tissues, saliva samples of healthy people and normal human oral keratinocytes (all P<0.05). Log-rank univariate analysis showed that hsa_circ_0000231 expression level, tumor differentiation degree and T stage were related to the survival of TSCC patients (all P<0.05). Multivariate Cox risk regression model analysis suggested that hsa_circ_0000231 expression level (χ2=5.77,P=0.016) and T stage (χ2=5.27,P=0.029) were independent factors for the poor prognosis of TSCC patients. Western blot showed the expressions of snail protein, N-cadherin and vimentin were down-regulated, but E-cadherin was up-regulated in interference group compared with control group. In interference group, the expressions of ß-catenin, C-myc, Bcl-2, MMP-9 and CyclinD1 were down-regulated, which were reversed after TSCC cells were co-cultured with LiCl. The knockdown of hsa_circ_0000231 reduced the proliferation, invasion and metastasis abilities of CAL-27 and Tca-8113 cells, which were reversed after TSCC cells were co-cultured with LiCl. The growth rate and volume of the tumors grafted subcutaneously in interference group using LiCl were greater than those in negative control group. Conclusion: hsa_circ_0000231 is an independent prognostic factor of TSCC. Highly expressed hsa_circ_0000231 can promote the proliferation, invasion and metastasis of TSCC cells.

Objective: To explore the application value of T lymphocyte subsets combined with procalcitonin (PCT), C-reactive protein (CRP), neutrophil to lymphocyte ratio (NLR) and white blood cell count (WBC) in the auxiliary diagnosis and prognosis evaluation of sepsis. Methods: In a retrospective study, seventy-two patients with sepsis diagnosed and treated in Tianjin First Central Hospital from June 2018 to April 2021 were selected as the research objects, and included in the sepsis group were 46 males and 26 females, aged 68 (57.3, 80.3) years. In addition, 111 patients with local infection admitted to hospital during the same period were included in the local infection group, including 62 males and 49 females, aged 68 (51, 77) years. Sepsis patients were divided into survival group (43 cases) and death group (29 cases) according to the 28-day outcome. CD3+, CD4+, CD8+, CD4+/CD8+ ratio were detected by flow cytometry within 24 h after admission, PCT was detected by ELISA, CRP was detected by immunoturbidimetry, blood routine examination, blood lactic acid (Lac) and oxygen partial pressure (PO2) were detected by instrumental method. Multivariate Logistic regression analysis was used to evaluate the correlation between each indicator and sepsis, and receiver operating characteristic curve (ROC) was drawn to evaluate the diagnostic value of each indicator for sepsis. Multivariate Logistic regression analysis and Kaplan Meier survival analysis were used to evaluate the prognostic value of each index for patients with sepsis. Results: Peripheral blood CD3+, CD4+, CD8+, CD4+/CD8+ ratio and PLT in sepsis group were significantly lower than those in local infection group(Z=-8.184,P<0.001;Z=-7.210,P<0.001;Z=-5.936,P<0.001;Z=-2.700,P=0.007;Z=-6.381,P<0.001); PCT, CRP, NLR and Lac levels were significantly higher than those in local infection group(Z=-8.262,P<0.001;Z=-3.094,P=0.002;Z=-9.004,P<0.001;Z=-4.770,P<0.001). Multivariate Logistic regression model showed that PCT, NLR, CD3+, CD8+, CD4+/CD8+ were independent risk factors for sepsis. According to ROC curve analysis, AUC of sepsis patients diagnosed by each indicator were 0.862, 0.894, 0.858, 0.760 and 0.618, respectively. The cut-off values were 3.075 ng/ml, 10.715, 44.935×109/L, 27.463×109/L and 0.750, respectively. The NLR sensitivity was 80.6%, and the CD3+ specificity was 94.6%. The AUC of combined detection of PCT and NLR was 0.947, sensitivity was 87.5% and specificity was 91.9%. The combined detection AUC of PCT, NLR, CD3+, CD4+/CD8+ was 0.958, the sensitivity and specificity were 90.3% and 91.0% respectively(P<0.001). PCT and Lac in death group were significantly higher than those in survival group(Z=-2.302,P=0.021;Z=-3.095,P=0.002);Peripheral blood CD4+/CD8+ levels were significantly lower than those in survival group(Z=-3.691,P<0.001),Multivariate Logistic regression model showed that CD4+/CD8+ ratio was an independent risk factor for 28 d mortality in patients with sepsis (P<0.001). The ROC curve showed that the AUC was 0.758, and the Youden index reached the maximum when the cut-off value was 1.27, the sensitivity and specificity were 79.3% and 60.5%, respectively. Compared with patients with CD4+/CD8+ ≥1.27, 28-day mortality was significantly increased in patients with CD4+/CD8+<1.27 (P=0.032). Conclusion: The combined detection of PCT, NLR, CD3+ and CD4+/CD8+ can improve the auxiliary diagnostic efficiency of sepsis, and the ratio of CD4+/CD8+ in peripheral blood may have certain predictive value for the prognosis of sepsis.

OBJECTIVE: To analyze the hospitalization cost and its influencing factors of imported malaria patients in Guangxi Zhuang Autonomous Region and Yunnan Province, so as to provide insights into the evaluation of the economic burden due to imported malaria, and the guiding of malaria control and the rational allocation of medical resources. METHODS: The data pertaining to the hospitalization costs of imported malaria patients admitted to Shanglin County People's Hospital in Guangxi Zhuang Autonomous Region during the period from January 1 through December 31, 2019, and Tengchong Municipal People's Hospital in Yunnan Province from January 1, 2015 to December 31, 2019, were collected, and the epidemiological data of these imported malaria patients were extracted from the Information Management System for Parasitic Diseases Control and Prevention, China. The composition of the hospitalization expenses was analyzed using a descriptive method. In addition, the factors affecting the hospitalization expenses of imported malaria patients were identified using a univariate analysis and a recursive system model. RESULTS: A total of 206 imported malaria patients were included in this study, including 194 men (94.17%) and 12 women (5.83%). The mean length of hospital stay was 5.00 days per patient and the median hospitalization expenses were 2 813.07 Yuan per time, in which the expenses for laboratory examinations were the highest (45.31%, 1 274.62/2 813.07). Univariate analysis showed that hospital (z = 5.43, P < 0.01), type of malaria (χ2 = 34.86, P < 0.01) and type of payment (χ2 = 7.72, P < 0.05) were factors affecting the hospitalization expenses of imported malaria patients. Recursion system modeling revealed that the total effects on hospitalization expenses of imported malaria patients included length of hospital stay (0.78), selection of hospital (0.34), basic medical insurance for urban and rural residents (0.19), new rural cooperative medical care (0.17), Plasmodium falciparum malaria (0.15), gender (0.11) and P. vivax malaria (0.09). CONCLUSIONS: The hospitalization expenses of imported malaria patients are affected by multiple factors in Guangxi Zhuang Autonomous Region and Yunnan Province, in which the length of hospital stay is the most predominant influencing factor. A reduction in the length of hospital stay is effective to decrease the hospitalization expenses of imported malaria patients.

Objective: To analyze the malignant probability of thyroid nodules with the diagnosis of atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS) determined by fine-needle aspiration (FNA) and to explore the value of the combined application of BRAFV600E gene detection for the diagnosis of benign and malignant thyroid nodules. Methods: A total of 114 patients including 20 males and 94 females, aged 16-76 years old with thyroid nodules underwent FNA examination and surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from October 2018 to November 2019 were retrospectively analyzed. Postoperative histopathological results were used as the gold standard for the diagnosis of malignant thyroid nodules. The malignant rate of thyroid nodules with the diagnosis of AUS/FLUS was evaluated. Differential diagnostic efficacy of preoperative FNA combined with BRAFV600E gene detection for papillary thyroid carcinoma (PTC) was analyzed by McNemer test and diagnostic test evaluation method. Results: The mutation rate of BRAFV600E gene was 84.76% (89/105) in PTC. PTC accounted for 57.14% (12/21) of the patients with the diagnoses of AUS/FLUS determined by FNA. The specificity, sensitivity, positive predictive value and negative predictive value of BRAFV600E mutation examination for the diagnosis of malignant thyroid nodules determined preoperatively as AUS/FLUS were 9/9, 5/12, 5/5 and 9/16, respectively. BRAFV600E mutation examination could improve the detection rate of PTC in patients with AUS/FLUS (OR=0.438, 95%CI=0.251-0.763, P=0.016). Conclusion: FNA combined with BRAFV600E mutation examination can significantly improve the detection rate of malignant thyroid nodules diagnosed preoperatively as AUS/FLUS.

BACKGROUND: Wheat-dependent exercise-induced anaphylaxis (WDEIA) is a severe allergic condition in which wheat ingestion together followed by physical exercise induces anaphylaxis. For patients with WDEIA, omega-5 gliadin is considered to be one of the major allergens. AIM: To analyse the clinical features and allergen spectrum of WDEIA and to investigate the relationship between WDEIA and serum levels of platelet-activating factor (PAF), interleukin (IL)-9 and IL-33. METHODS: Medical histories and conditions of WDEIA cases were collected and summarized, with allergen tests of wheat proteins measured at the same visit. Of the 33 patients enrolled, 13 also had serum levels of PAF, IL-9 and IL-33 measured. The healthy control (HC) group consisted of 13 healthy individuals, who also underwent both the wheat-protein allergen tests and the inflammatory-mediator tests. RESULTS: All patients experienced severe allergic reaction during exercise after wheat ingestion. Manifestations of WDEIA included facial oedema, generalized urticaria and respiratory symptoms. Unconsciousness was also observed in 21 cases. In the patient group, 57.6% were confirmed as hypersensitive to glyceraldehyde-3-phosphate dehydrogenase (GAPDH), while 54.5% were allergic to omega-5 gliadin. PAF concentration was significantly higher in patients with WDEIA compared with HCs, whereas there was no significant difference in IL-9 or IL-33 between the two groups. CONCLUSIONS: WDEIA is a rare type of anaphylaxis. GAPDH and omega-5 gliadin may be the most common allergy-causing wheat proteins for Chinese people. PAF may be associated with the onset and development of WDEIA.

Objective: To analyze the diagnostic value of skeletal muscle biopsy in patients with rhabdomyolysis. Methods: Clinical and pathological data of 26 patients with rhabdomyolysis from January 2002 to December 2018 undergoing muscle biopsy were collected. Results: Eighteen males and 8 females were finally recruited with median age of 6-73 (37.3±19.6) years. The average time from onset to biopsy was 44 days (median course was 30 days). All patients had acute manifestations with muscle pain and/or weakness. Serum creatine kinase was between 1 648-92 660 U/L. Muscle biopsies showed nonspecific changes in 12 cases (a few with type 2 muscle fiber atrophy, slight deposition of lipid droplets), 10 cases with necrotizing myopathy (muscle fiber necrosis and regeneration). Toxic neurogenic damages were seen in 2 cases (type 1 and type 2 angular atrophic muscle fibers with group change), lipid storage disease in 1 case (lipid droplets deposit significantly) and idiopathic inflammatory myopathy in 1 case (muscle fiber necrosis and regeneration, with lymphocyte infiltration). The etiology of non-specific pathological changes included short-term strenuous exercise in 6 patients, poisoning in two, chronic kidney disease in one, viral infection in one, hypothyroidism in one and unknown reason in one. As to patients with necrotizing myopathy, seven were poisoning or drug-related, one with hyperthyroidism, two with unknown reason. Conclusions: Among the numerous causes of rhabdomyolysis, exercise usually links nonspecific skeletal muscle changes and poisoning or drug-related disorders are commonly associated with necrotic myopathy. Rhabdomyolysis induced by primary myopathy is rare.

A farm worker in Baodi District of Tianjin was diagnosed with Tsutsugamushi disease due to fever and intermittent cough for more than 3 months.The patient's diagnosis and treatment process was complicated, and the diagnosis was delayed in the early stage of the disease because the clinician neglected the occupational history and lacked knowledge about the prevention and control of tsutsugamushi disease. As an important part of the epidemiological history, occupational history is crucial for the diagnosis of occupational related diseases. Clinical thinking runs through the whole process of clinical diagnosis and disease treatment, and correct clinical thinking can effectively reduce the occurrence of misdiagnosis.Clinicians should ask and record career history in detail to improve the quality of health care.
