Objective To understand the clinical features of infant pulmonary hemorrhage of enterovirus 71 infection without skin rash, and to improve the diagnosis and treatment of this disease.Methods Six infants infected with enterovirus 71 and presented pulmonary hemorrhage but no skin rash between November 2007 and October 2008 were retrospectively reviewed. The clinical manifestations, clinical outcomes, treatments, laboratory data and chest imaging changes of the cases were analyzed. Results The 6 cases were all younger than 2 years old. The cases distributed throughout the whole year without peak season. Enterovirus 71 gene was detected by reverse transcription-polymerase chain reaction (RT-PCR) and real time polymerase chain reaction from throat swabs and secretions of the respiratory tract. All the cases began with fever, and 4 of which were accompanied with vomit, and 2 accompanied with cough. After 1 to 3 days, they all got sudden deterioration, manifested with pale and cyanosis, and 1 had hyperspasmia. After intubation, they all had pink frothy fluid from the endotracheal tube. They all had obvious hyperglycaemia, 4 had tachycardia, and 2 had hypertension. All the 6 cases died, and 4 died within 6 h after deterioration. Conclusions Pulmonary hemorrhage of enterovirus 71 infection without skin rash is seen in infants. It is sporadic throughout the whole year. The disease is fulminant and the case often dies in short period of time.

Objective:To investigate the pathological characteristics in chronic HBV infection patients with different upper limits of alanine aminotransferase (ALT) normal values and the influencing factors of liver tissue injury.Methods:The clinical data of 667 chronic HBV infection patients with ALT<40 U/L and HBV DNA loads >30 IU/mL who received liver biopsy in Zhenhai District Hospital of Traditional Chinese Medicine and Hwa Mei Hospital from January 2014 to December 2020 were retrospectively analyzed. The enrolled patients were divided into ALTⅠ group (<30 U/L for males, <19 U/L for females), ALTⅡ group (≥30 U/L and <35 U/L for males, ≥19 U/L and <25 U/L for females) and ALT Ⅲ group (≥35 U/L and <40 U/L for males, ≥25 U/L and <40 U/L for females). According to the degree of liver inflammation (G) and fibrosis stage (S), the enrolled patients were divided into non-significant damage group (G<2 and S<2) and significant damage group (≥G2 or/and ≥S2). Ridit analysis was used to compare the G/S composition ratio among three ALT groups, Logistic regression was used to analyze the risk factors of liver injury, the receiver operating characteristic curve (ROC) and the area under the curve (AUC) were used to analyze the optimal diagnostic threshold of ALT.Results:There were significant differences in the composition ratio of G and S among the three ALT groups( χ2=13.926 and 14.702, both P<0.001). The constituent ratios of significant liver pathological damage in the three groups of ALT levels were 26.05% (99/380), 32.03% (41/128) and 46.54% (74/159), respectively( χ2=21.596, P<0.001). Multivariate logistic regression analysis showed that high white/globulin ratio and PLT counts( OR=0.246 and 0.986, both P<0.001)were the protective factors for liver tissue injury; while negative HBcAg staining and elevated ALT and GGT levels ( OR=3.797, 1.053 and 1.013, P<0.001 or <0.05) were the risk factors of liver injury. ROC curve demonstrated the ALT threshold of liver tissue damage in male and female patients were 25.6 U/L and 25.5 U/L. Conclusions:In chronic HBV infection patients with normal ALT, with the increase of ALT level, the degree of liver tissue pathological damage may become more severe. The study demonstrates that it is necessary to lower the ALT threshold for protecting patients from liver tissue pathological damage.

AIM: To explore the effect of Bcl-2 small molecule inhibitor ABT-737 on the growth and angiogenesis mimicry of SKOV3 cells in a co-culture system of Tumour-associated macrophages (TAMs) and human ovarian cancer cells SKOV3. METHODS: PMA and IL-4 was used to induce THP-1 cells into TAMs cells in vitro; MTT method was used to detect the cell survival rate of SKOV3 cells after 24 hours of treatment with different concentrations of ABT-737 culture medium; a co-culture system of SKOV3 cells and TAMs cells was established; the experimental groups were divided into control group, SKOV3+ABT-737 group (containing 5.0 μmol/L ABT-737 cultured cells), TAMs+SKOV3 group (SKOV3 cells co-cultured with TAMs cells), TAMs+SKOV3+ABT-737 group (SKOV3 cells Co-cultured with TAMs cells, and added ABT-737 containing 5.0 μmol/L), cells after 24 h was collected, MTT method was used to detect cell survival rate, EdU staining for cell proliferation, ranswell chamber experiment for cell migration and invasion, Flowcytometry for cell apoptosis, the vascular mimicry experiment for the ability of cells to form blood vessels, Western blot for the expression of vascular endothelial growth factor (VEGF), matrix metalloproteinase-2 (MMP-2) and MMP-9 in cells. RESULTS: THP-1 cells were successfully induced for TAMs cells; the survival rate of SKOV3 cells decreased under the action of ABT-737 (P<0.01); compared with the control group, the survival rate of SKOV3 cells in the SKOV3+ABT-737 group decreased, the number of EdU-labeled positive cells decreased, the number of cell migration and invasion also decreased, the rate of apoptosis increased, and the duct branches decreased, The protein expression of VEGF, MMP-2, MMP-9 decreased (P<0.01); Compared with the TAMs+SKOV3 group, the cell survival rate of the TAMs+SKOV3+ABT-737 group decreased, the number of EdU-labeled positive cells and the number of cell migration and invasion also decreased, the apoptosis rate increased, and the duct branches decreased. At the same time, the protein expression of VEGF, MMP-2, MMP-9 decreased (P<0.01). CONCLUSION: ABT-737 can inhibit SKOV3 cell proliferation, metastasis, apoptosis and angiogenesis in a co-culture system, and affect tumor progression.

OBJECTIVETo analyze the clinical manifestations and intervention against fulminant scrub typhus-associated hemophagocytic syndrome.
METHODThe medical records for the onset time of hemophagocytic syndrome, the clinical course, the chest radiographic findings, laboratory data, antibiotic therapy, clinical outcome and its prognosis were retrospectively reviewed.
RESULT(1) Four patients were diagnosed as scrub typhus based on clinical manifestations only, while 15 patients met the criteria of laboratory diagnosis. All 19 patients with scrub typhus had hemophagocytic syndrome. Eschar lesion was identified in 12 patients, 7 patients were described as an ulcer. A seasonal pattern (78.9% from June through September in 15 patients) was observed. Clinical misdiagnosis was common (all 19 cases). There were 9 patients with admitting diagnosis of scrub typhus, 10 patients were not diagnosed as scrub typhus after admission. In 5 cases within 3 days after admission diagnosis was corrected as scrub typhus. Until discharge from the hospital, 5 cases were not diagnosed with scrub typhus. In this study, the length of time from the illness onset (beginning of fever) to the occurrence of clinical symptoms was (9 ± 4) days. (2) All 19 patients had changed AST levels (149 ± 37) U/L, albumin levels (23 ± 4) g/L, C-reactive protein levels (103 ± 51) mg/L, and platelet count (48 ± 41) × 10⁹/L; bone marrow aspiration revealed in 16 patients marked hemophagocytosis. Weil-Felix agglutination test revealed positive results in 6 of 15 cases. Diagnostic IFA results were positive for 14 patients; 19 patients had interstitial pneumonitis and 17 patients had pleural effusion. (3) Five cases with failure to diagnose the disease had ineffective antibiotics treatment (imipenem or β-lactam-based regimens). These patients did not receive appropriate treatment with antibiotics against scrub typhus. Fourteen patients with admitting diagnosis of scrub typhus were successfully treated with appropriate antibiotics, 8 cases with chloramphenicol, 3 cases with azithromycin, and in 3 patients (2 cases of azithromycin and one case of erythromycin), therapy was then switched to chloramphenicol. Four patients were treated with methylprednisolone and 10 patients with dexamethasone. (4) During their hospitalization, the clinical course in five cases with failure to diagnose the disease rapidly developed and progressed to the life-threatening MODS, four of five cases died. However, the course in 14 patients were relieved and did not progress to MODS.
CONCLUSIONThe diagnosis of scrub typhus was frequently delayed, the early course of scrub typhus could be associated with hemophagocytic syndrome. Serious complications of MODS generally occur without antibiotic treatment. Scrub typhus-associated hemophagocytic syndrome should be taken into consideration among patients with acute systemic febrile illness, significant increases in levels of CRP, hypoalbuminemia, thrombocytopenia, splenomegaly, pneumonitis with pleural effusion, especially those with suspected exposure history. It was not easily recognized without careful observation and was present for a few days in each patient.

Objective:To analyze the liver pathology, clinical characteristics and influence factors in patients with chronic hepatitis B virus (HBV) infection in immune tolerant phase (IT).Methods:The clinical data of 273 patients in IT phase who underwent liver biopsy from January 2015 to December 2019 were included in this study. The correlation between liver pathological changes and clinical features was analyzed.Results:There were 43 cases (15.75%) with liver histologic activity ≥ G2, 30 cases (10.99%) with liver fibrosis ≥ S2, and 55 cases (20.15%) with liver pathology ≥ G2 and/or ≥ S2. A total of 17.95% patients had liver steatosis. The majority (98.17%) of tissue samples were positive for HBsAg staining, while only 79.49% were positive for HBcAg. The characteristics of liver pathology were comparable in men from women patients. The differences of G and S were not statistically significant according to different HBsAg positivity, while those were statistically significant according to different HBcAg positivity. By univariate and multivariate analysis, the independent risk factors of pathological severity were HBcAg intensity, HBeAg level, and age. However, the differences of liver histologic activity and fibrosis were not statistically significant between those younger than 30 years old group from those older than 30 years old, neither between those younger or older than 40. Although the diagnostic value of liver inflammation and fibrosis 5 (LIF-5) was better than that of aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis 4 score (FIB-4), three diagnostic models for predicting the pathological severity were not strong enough (all area under the curves<0.8). Only the specificity of LIF-5 for predicting≥ G2, ≥ G2 and/or ≥ S2 was over 80%.Conclusions:Approximately 20% patients with chronic HBV infection in IT phase have progressive liver inflammation or fibrosis. The intensity of liver HBcAg and HBeAg level are negatively correlated with the severity of disease. The diagnostic models or most clinical indicators have low predictive effect for chronic HBV infections in IT phase.
