Preliminary study on the value of fetal MRI lung volume and mediastinal shift angle for predicting prognosis of left congenital diaphragmatic hernia / 中华放射学杂志

Objective:To explore the value of fetal lung volume and mediastinal shift angle (MSA) based on fetal MRI in predicting the prognosis of congenital diaphragmatic hernia (CDH).Methods:Fetuses with left CDH that did fetal MRI in Xinhua Hospital Affiliated with Shanghai Jiao Tong University School of Medicine from September 2016 to January 2022 were retrospectively collected. There were 65 patients, and their gestational age was 29 (26, 35) weeks when they were diagnosed with left CDH by MRI. Observed fetal lung volume and MSA were measured based on fetal MRI, and observed/expected lung volume (o/eFLV) based on gestational age was calculated. The clinical data were collected from birth to discharge, and patients were divided into survival group and death group in case of prognosis at discharge, with 54 cases in the survival group and 11 cases in the death group. The student′s t test was used to compare the difference of o/eFLV and MSA between the survival group and the death group, and the receiver operating characteristic (ROC) curve was used to evaluate the value of o/eFLV and MSA in predicting the prognosis of left CDH. Results:The o/eFLV of the survival group was 51.5%±18.3%, higher than that of the death group (27.8%±4.4%), and the difference was significant ( t=8.29, P<0.001). The MSA of the survival group was 33.1°±1.2°, lower than that of the death group (41.8°±2.7°), and the difference was significant ( t=-11.15, P<0.001). The area under the ROC curve (AUC) of o/eFLV to predict the fetal survival or death was 0.939 (95%CI 0.851-0.983), the cutoff value was 33.8%, the sensitivity was 100%, the specificity was 88.9%. The AUC of MSA was 0.998 (95%CI 0.941-1.000), the cutoff value was 37.2°, the sensitivity was 100%, the specificity was 98.2%. Conclusions:The o/eFLV and MSA that were measured based on fetal MRI can effectively predict the fetus′s prognosis with left CDH.

Dysregulated expression of miR-92a-3p in senile osteoporosis and its diagnostic value in hip fragility fractures / 中华内分泌外科杂志

Objective:To investigate the expression of miR-92a-3p in senile osteoporosis (OP) and its diagnostic value in hip fragility fractures.Methods:With the help of the National Center for Biotechnology Information (NCBI) website, the data sets related to OP and miRNA were retrieved and analyzed and screened to obtain the target miRNA. Serum samples were collectedfrom 53 OP patients and 24 healthy people, and the OP patients were divided into hip fragility fracture group (OP_F; n=30) and no hip fragility fracture group (OP_WF; n=23). The subjects' bone mineral density and serum bone metabolism markers were measured: calcium, phosphorus, parathyroid hormone, 25-hydroxyvitamin D, bone alkaline phosphatase, serum C-terminal peptide. The expression levels of target miRNAs in serum samples were detected by qRT-PCR. Chi-square test, t test, Spearman rank correlation and receiver operating characteristic curve (ROC curve) were used to analyze the potential relationship between the expression level of miR-92a-3p and the clinical characteristics of patients.Results:According to the analysis of NCBI website, the expression of miR-92a-3p in OP patients was higher ( t=3.41, P=0.007) than that in healthy people, and the expression level of miR-1304-5p was lower ( t=5.13, P<0.001). qRT-PCR experiments confirmed the above results, and further found that the expression of miR-92a-3p in the OP_F group was significantly higher than that in the OP_WF group (t=3.01, P=0.004), but there was no significant difference in miR-1304-5p between the two groups (t=0.71, P=0.480). Compared with the healthy control group, the BMI ( t=2.71, P=0.008), bone mineral density score ( t=29.02, P<0.001), calcium ( t=61.20, P<0.001), phosphorus ( t=2.54, P=0.013), 25-hydroxyvitamin D (t=3.01, P=0.004) ,bone alkaline phosphatase ( t=12.56, P<0.001), and serum C-terminal peptide ( t=7.52, P<0.001) levels were statistically different between the OP patient group and the healthy control group. Compared with the OP_WF group, the bone mineral density score ( t=2.08, P=0.042), calcium ( t=15.75, P<0.001), bone alkaline phosphatase ( t=2.02, P=0.049) and serum C-terminal peptide ( t=3.39, P=0.001) levels were statistically different between the OP_F group and the OP_WF group. Bone mineral density score and bone alkaline phosphatase concentration were related to the expression of miR-92a-3p and were negatively and positively correlated ( r=0.416, P=0.022), respectively ( r=-0.403, P=0.027). The area under the ROC curve was 0.723, and the level of miR-92a-3p had potential significance in the diagnosis of hip fragility fractures ( P=0.006) . Conclusion:miR-92a-3p is highly expressed in OP and has biological significance for the diagnosis of hip fragility fractures.

Pancreatitis, panniculitis, and polyarthritis / 中华风湿病学杂志

Objective To improve the recognition of Pancreatitis, Panniculitis, and Polyarthritis syndrome (PPP syndrome). Methods We described the diagnosis and treatment of a patient with PPP syndrome, including the clinical, radiological, and pathological features. Results Here we report a 67-year-old man with chronic calcified pancreatitis with multiple subcutaneous nodules and polyarthritis, but without any abdominal pain or other abdominal symptoms. His serum pancreatic amylase and lipase were markedly elevated. Abdomen CT scan showed features of chronic calcified pancreatitis. MR imaging of ankle revealed intramedullary fat necrosis. Biopsy from subcutaneous swellings revealed fat necrosis without vasculitis and typical "ghost-like cells". He failed to response to corticosteroids therapy. When the diagnosis of pancreatitis was confirmed, he was managed conservatively with supportive measures, and recovered. Conclusion The diagnosis of PPP syndrome is often difficult when abdominal symptoms are absent, be aware the association between panniculitis and polyarthritis with pancreatic disease may lead to a prompt diagnosis and management.

Effect of Inonotus Obliquus Polysaccharides on physical fatigue in mice.

OBJECTIVE: To evaluate the potential beneficial effects of Inonotus obliquuspolysaccharides (IOP) on the alleviation of physical fatigue in mice. METHODS: Sixty-four male mice were randomly divided into four groups (n = 16 per group). Mice were orally administered IOP for a period of 14 days at 0, 100, 200 and 300 mg/kg/d, and were assigned to the control, IOP-100, IOP-200, and IOP-300 groups, respectively by the random number table method. Mice in the control group received an oral administration of sterile distilled water. A forced swimming test was performed for 8 mice per group at one hour after the last treatment. The other 8 mice in each group swam for 30 min. Blood, liver and muscle samples were taken after resting for 30 min. Levels of blood urea nitrogen and lactate, as well as glycogen contents of the liver and muscle were measured. Morphology of liver was observed by light microscopy. RESULTS: IOP extended the swimming time of mice, and increased the glycogen content of liver and muscle, but decreased blood lactic acid and serum urea nitrogen levels, IOP had no toxic effects on major organs such as the liver as assessed by histopathological examinations. CONCLUSION: IOP might be a potential anti-fatigue pharmacological agent.

Protective Effects of Inonotus Obliquus Polysaccharide on Liver Injury Induced by Anti-tuberculosis Drugs in Mice / 医药导报

Objective To study the protective effect and mechanism of Inonotus obliquus polysaccharide on liver injury induced by isoniazid( INH) combined with rifampicin( RFP) in mice. Methods Forty-eight mice were randomly divided into six groups ( control, model, huganpian, Inonotus obliquus polysaccharide at low, middle, and high dose ) . The mice were administered orally with isoniazid and rifampicin simultaneously except the control. After 2 h,the control and model groups were administered with normal saline,and others were treated with huganpian and Inonotus obliquus polysaccharide,respectively,once a day for 2 weeks. The liver index and serum levels of ALT and AST,malondialdehyde(MDA),superoxide dismutase(SOD) and glutathione peroxidase( GPx) were measured. Pathology examination of liver tissue was performed. Results The activities of ALT and AST, liver index, content of MDA in liver homogenate of mice treated with Inonotus obliquus polysaccharide and huganpian decreased obviously, while the liver SOD activity increased. Histopathological exzamination showed that Inonotus obliquus polysaccharide alleviated the degeneration and necrosis of hepatic cells. Conclusion Inonotus obliquus polysaccharide shows protective effects on mice with hepatic toxic injury induced by isoniazid and rifampicin,which maybe due to its antioxidation effect.
