This paper reports the discovery, diagnosis, treatment, and epidemiological survey of an imported confirmed visceral leishmaniasis (kala-azar) case in Wuhan City, providing a reference experience for enhancing awareness of imported visceral leishmaniasis among medical professionals in non-endemic healthcare institutions and reducing misdiagnosis. The patient had worked in Yangquan, Shanxi Province, for more than one year. After returning to his hometown in Hubei Province in 2020, he began to show symptoms such as intermittent fever, pancytopenia, progressive splenomegaly, and significant weight loss. Leishmania amastigotes were found in bone marrow smears. The rapid diagnostic test using the rk39 strip was positive for antibodies. Furthermore, both loop-mediated isothermal amplification (LAMP) and quantitative polymerase chain reaction (qPCR) assays confirmed the presence of Leishmania nucleic acid. Based on a comprehensive analysis of the epidemiological history, clinical manifestations, and laboratory test results, the case was confirmed as an imported visceral leishmaniasis case. This case presented with low parasite density and abnormal autoimmune indicators such as increased rheumatoid factor, leading to its prolonged misdiagnosis as a hematologic or autoimmune disease without effective treatment. It was only diagnosed after having left the endemic area for four years. Non-endemic areas should pay attention to the inquiry of epidemiological history and improve healthcare institutions' diagnostic awareness and treatment capabilities related to visceral leishmaniasis to avoid delays in treatment.

OBJECTIVE: To investigate lymph node metastasis (LNM) in the prostatic anterior fat pad (PAFP) of PCa patients after robot-assisted radical prostatectomy (RARP), and analyze the clinicopathological features and prognosis of LNM in the PAFP. METHODS: We retrospectively analyzed the clinicopathological data on 1 003 cases of PCa treated by RARP in the Department of Urology of PLA General Hospital from January 2017 to December 2022. All the patients underwent routine removal of the PAFP during RARP and pathological examination, with the results of all the specimens examined and reported by pathologists. Based on the presence and locations of LNM, we grouped the patients for statistical analysis, compared the clinicopathological features between different groups using the Student's t, Mann-Whitney U and Chi-square tests, and conducted survival analyses using the Kaplan-Meier and Log-rank methods and survival curves generated by Rstudio. RESULTS: Lymph nodes were detected in 77 (7.7%) of the 1 003 PAFP samples, and LNM in 11 (14.3%) of the 77 cases, with a positive rate of 1.1% (11/1 003). Of the 11 positive cases, 9 were found in the upgraded pathological N stage, and the other 2 complicated by pelvic LNM. The patients with postoperative pathological stage≥T3 constituted a significantly higher proportion in the PAFP LNM than in the non-PAFP LNM group (81.8% ［9/11］ vs 36.2% ［359/992］, P = 0.005), and so did the cases with Gleason score ≥8 (87.5% ［7/8］ vs 35.5% ［279/786］, P = 0.009). No statistically significant differences were observed in the clinicopathological features and biochemical recurrence-free survival between the patients with PAFP LNM only and those with pelvic LNM only. CONCLUSION The PAFP is a potential route to LNM, and patients with LNM in the PAFP are characterized by poor pathological features. There is no statistically significant difference in biochemical recurrence-free survival between the patients with PAFP LNM only and those with pelvic LNM only. Routine removal of the PAFP and independent pathological examination of the specimen during RARP is of great clinical significance.

OBJECTIVES: To explore the underlying pharmacological mechanisms and its potential effects of Chinese medicine herbal formula Sini Powder (SNP) on hepatocellular carcinoma (HCC). METHODS: The active components of SNP and their in vivo distribution were identified using ultraperformance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. Construction of component-target-disease networks, protein-protein interaction network, Gene Ontology function and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis, and molecular docking were employed to analyze the active components and anti-HCC mechanisms of SNP. Cell viability assay and wound healing assay were utilized to confirm the effect of SNP-containing serum (2.5%, 5.0%, 10%, 20%, and 40%), isoprenaline or propranolol (both 10, 100, and 1,000 µ mol/L) on proliferation and migration of HepG 2 or Huh7 cells. Meanwhile, the effect of isoprenaline or propranolol on the β 2 adrenergic receptor (ADRB2) mRNA expression on HepG2 cells were measured by real-time quantitative reverse transcription (RT-qPCR). Mice with subcutaneous tumors were either subjected to chronic restraint stress (CRS) followed by SNP administration (364 mg/mL) or directly treated with SNP (364 mg/mL). These two parallel experiments were performed to validate the effects of SNP on stress responses. Stress-related proteins and hormones were quantified using RT-qPCR, enzyme-linked immunosorbent assay, and immunohistochemistry. Metagenomic sequencing was performed to confirm the influence of SNP on the gut microbiota in the tumor-bearing CRS mice. RESULTS: The distribution of the 12 active components of SNP was confirmed in various tissues and feces. Network pharmacology analysis confirmed the anti-HCC effects of the 5 active components. The potential anti-HCC mechanisms of SNP may involve the epidermal growth factor receptor (EGFR), proto-oncogene tyrosine-protein kinase Src (SRC) and signal transducer and activator of transcription 3 (STAT3) pathways. SNP-containing serum inhibited the proliferation of HepG2 and Huh7 cells at concentrations of 2.5% and 5.0%, respectively, after 24 h of treatment. Furthermore, SNP suppressed tumor progression in tumor-bearing mice exposed to CRS. SNP treatment also downregulated the expressions of stress-related proteins and pro-inflammatory cytokines, primarily by modulating the gut microbiota. Specifically, the abundance of Alistipes and Prevotella, which belong to the phylum Bacteroidetes, increased in the SNP-treated group, whereas Lachnospira, in the phylum Firmicutes, decreased. CONCLUSION SNP can combat HCC by alleviating stress responses through the regulation of gut microbiota.

Objective To report a case of synovial sarcoma of the liver and review the literature for improving the understanding of the disease.Methods The clinical data of a patient with liver synovial sarcoma admitted to the First Affiliated Hospital of Henan University were analyzed retrospectively.The imaging,pathological features,treatment and prognosis of this disease were summarized by searching the database(CNKI,Wanfang Data,PubMed,untill July 2022)and the literature results analyzed comprehensively.Results The patient was a 71-year-old female who was admitted to the hospital due to abdominal pain.Computed tomography(CT)scan showed a mass with mixed density in the right lobe and caudate lobe of the liver.The large cross section size was about 115 mm×87 mm and the mass showed continuous heterogeneous enhancement,being considered as malignant hepatic tumors with multiple metastasis of the liver and lung.Ultrasound-guided needle biopsy was performed,and microscopy showed the tumor cells were obvious atypical,and some were spindle-shaped.Immunohistochemistry showed that the patient was positive for vimentin(VIM),epithelial membrane antigen(EMA),methylation of histone at lysine 27(H3K27Me3),and negative for pan cytokeratin(CK-pan)and S-100,and pathological diagnosis of synovial sarcoma was made.The patient did not undergo subsequent treatment and was lost to follow-up after discharge.A total of 12 cases of hepatic synovial sarcoma were reported after searching the database.The clinical manifestations were abdominal pain or distention.The lesions were mostly located in the right lobe of the liver,usually large,heterogeneous density,and heterogeneous enhancement on enhanced CT or magnetic resonance imaging(MRI).Spindle-shaped cells were found at histopathologic examination.Immunohistochemistry showed the patient was positive for VIM,EMA,H3K27Me,B-cell leukemia/lymphoma-2(BCL-2)and transducer-like enhancer of split 1(TLE1).SS18-SSX fusion gene or SS18 gene isolation were detected.Eleven patients received surgical treatment,5 received adjuvant chemotherapy,and 4 had recurrence or metastasis during the follow-up period.Conclusions Synovial sarcoma of the liver is a rare malignant tumor of the liver.The clinical and imaging features are not specific.The diagnosis depends on pathology.At present,the main treatment is surgery,and comprehensive treatment such as adjuvant chemotherapy can be performed.The prognosis of the patient is poor.

In the European Guideline on Management of Major Bleeding and Coagulopathy Following Trauma updated recently, there are 39 clinical practice recommendations that follow an approximate temporal path for management of the bleeding trauma patient, with recommendations grouped behind key decision points, including initial resuscitation and prevention of further bleeding, diagnosis and monitoring of bleeding, rapid control of bleeding, initial management of bleeding and coagulopathy, further goal-directed coagulation management, management of antithrombotic agents, thromboprophylaxis, guideline implementation and quality control, as welll as the management of tissue oxygenation, volume, fluids and temperature. In this paper, we introduce the recommendations and rationale of the guideline and add some newly published clinical study evidence. These information would be very helpful to the development and training of the guidelines or protocols for the management of the trauma patient with major haemorrhage and coagulopathy in China.

Objective To study the expression of miR-205 and miR-367 in cutaneous malignant melanoma(CMM)tissue and their relationships with clinicopathological characteristics and prognosis.Methods The tumor tissues from 85 patients with CMM who were admitted to our hospital from May 2013 to December 2019 were selected as the CMM group,and the nevus tissue samples from 80 patients with benign pigmented nevi who were treated in our hospital during the same period were selected as the control group.The expression level of miR-205 and miR-367 of two groups were detected by qRT-PCR.The clinical and pathological data of patients with CMM were collected,and the relationships between the expression of miR-205 and miR-367 and clinicopathological characteristics were analyzed.Kaplan-Meier was used to draw the survival curves of patients 3 years after surgery,and the survival rate of patients was analyzed by Log-rank test.The influencing factors of prognosis was analyzed by COX proportional risk regression model.Results The expression level of miR-205 of patients in the CMM group was lower than that in the control group,and the expression level of miR-367 was higher than that in the control group(P<0.05).The proportions of patients with ulceration,high clinical stage,tumor invasion,low KPS score,thick primary lesion,high Clark grade,lymph node metastasis in the miR-205 low-expression group were higher than those in the miR-205 high-expression group(P<0.05),the proportions of patients with the above indexes in the miR-367 high-expression group were higher than those in the miR-367 low-expression group(P<0.05).Patietns were followed up for 3 years,with a median time of 28.3 months,and 1 case was lost to followed-up.The Kaplan-Meier survival curve showed that the 3-year survival rate of patients in the miR-205 high-expression group was higher than that in the miR-205 low-expression group(P<0.05),and the 3-year survival rate of patients in the miR-367 low-expression group was higher than that in the miR-367 high-expression group(P<0.05).COX multivariate regression analysis showed that the high clinical stage,low KPS score,high Clark grade,lymph node metastasis,and high expression of miR-367 were the risk factors for prognosis of patients,while high expression of miR-205 was a protective factor(P<0.05).Conclusion Low expression of miR-205 and high expression of miR-367 in CMM tissue are associated with ulceration,high clinical stage,tumor invasion,low KPS score,thick primary lesion,high Clark grade,lymph node metastasis,and poor prognosis.These two indicators may serve as potential biomarkers for prognostic evaluation in CMM patients.

AIM To investigate the effects of Ginkgo biloba extract on hearing function,cochlear morphology and autophagy-related protein expression in a rat model of presbycusis.METHODS Forty-five rats were randomly divided into the control group,the model group and the low,medium and high dose G.biloba extract groups(10,20 and 30 mg/kg),with 9 rats in each group.The rat model of presbycusis was established by intraperitoneal injection of 500 mg/kg D-galactose(D-gal).Eight weeks after the corresponding administration,the rats had their changes of hearing threshold detected by the auditory brainstem evoked potential(ABR);their morphological changes of cochlear hair cells,stria vascularis(SV)and spiral ganglion cells observed by HE staining;their number of hair cells inside and outside the cochlea detected by immunofluorescence staining;their ultrastructure changes of cochlear hair cells observed by transmission electron microscopy;and their expression of autophagy-related proteins in cochlea tissue detected by Western blot.RESULTS Compared with the control group,the model group displayed increased ABR threshold(P<0.01);more severely damaged inner and outer hair cells,spiral ganglion cells and SV,decreased SV thickness and numbers of spiral ganglion cells,inner and outer hair cells and autophagosomes(P<0.01);decreased protein expressions of Beclin1 and LC3 Ⅱ and ratio of LC3 Ⅱ/LC3 Ⅰ in cochlear tissue(P<0.01),and higher P62 protein expression(P<0.01).Compared with the model group,the medium and high dose G.biloba extract groups shared decreased ABR thresholds(P<0.01);improved morphology of inner and outer hair cells and SV in the cochlea,normalized,morphology of spiral ganglion cells,and increased SV thickness and the numbers of spiral ganglion cells,inner and outer hair cells and autophagosomes(P<0.05,P<0.01);increased protein expressions of Beclin1 and LC3 Ⅱ and the ratio of LC3 Ⅱ/LC3 Ⅰ in the cochlea(P<0.01),and decreased P62 protein expression(P<0.01).CONCLUSION The protective effects G.biloba extract on hearing function and cochlear cells in the rat model of presbycusis may be associated with the up-regulated expression of Beclin1 and LC3 Ⅱ proteins and down-regulated P62 protein expression in cochlear tissues.
