Effectiveness of Scutellaria baicalensis Georgi root in pregnancy-related diseases: A review / 中西医结合学报

The root of Scutellaria baicalensis Georgi, also called Huangqin, is frequently used in traditional Chinese medicine. In ancient China, S. baicalensis root was used to clear heat, protect the fetus, and avoid a miscarriage for thousands of years. In modern times, pregnancy-related diseases can seriously affect maternal and fetal health, but few systematic studies have explored the mechanisms and potential targets of S. baicalensis root in the treatment of pregnancy-related diseases. Flavonoids (baicalein, wogonin and oroxylin A) and flavonoid glycosides (baicalin and wogonoside) are the main chemical components in the root of S. baicalensis. This study presents the current understanding of the major chemical components in the root of S. baicalensis, focusing on their traditional uses, potential therapeutic effects and ethnopharmacological relevance to pregnancy-related disorders. The mechanisms, potential targets and experimental models of S. baicalensis root for ameliorating pregnancy-related diseases, such as recurrent spontaneous abortion, preeclampsia, preterm birth, fetal growth restriction and gestational diabetes mellitus, are highlighted.

Objective:To explore the value of 18F-FDG PET/CT combined with pro-gastrin-releasing peptide (ProGRP) and neuron-specific enolase (NSE) in diagnosis and differential diagnosis of stageⅠA small cell lung cancer (SCLC). Methods:From June 2017 to October 2021, 113 patients (75 males, 38 females; age 32-79 years) with stageⅠA lung cancer (70 with adenocarcinoma, 25 with squamous cell carcinoma, 18 with SCLC; patients with adenocarcinoma and squamous cell carcinoma were combined into non-SCLC (NSCLC) group) and 30 patients with benign pulmonary nodule (21 males, 9 females; age 37-77 years) from the Affiliated Qingdao Central Hospital of Qingdao University were retrospectively analyzed. All patients were examined by 18F-FDG PET/CT and serum tumor markers associated with lung cancer. Differences of the clinical, imaging and tumor markers data among different groups were analyzed by χ2 test, Fisher exact test and Kruskal-Wallis rank sum test. Independent risk factors were analyzed by logistic regression analysis and ROC curve analysis was used to analyze the value of different predictive factors in diagnosis and differential diagnosis of SCLC. Results:There were significant differences in SUV max, lobulation sign, spiculation sign, calcification, pleural traction sign, ProGRP, NSE and carcinoembryonic antigen (CEA) among SCLC, NSCLC and benign nodules groups ( H values: 14.06-20.54, χ2 values: 8.16-14.95, all P<0.05), in which lobulation sign of SCLC was more than that of benign nodules (12/18 vs 26.7%(8/30); χ2=7.41, P=0.007), spiculation sign (2/18 vs 51.6%(49/95); χ2=10.01, P=0.002) and pleural traction sign (1/18 vs 35.8%(34/95); χ2=6.47, P=0.011) were less than those of NSCLC, SUV max was higher than that of benign nodules (7.4(5.8, 9.0) vs 2.3(1.4, 5.1); H=51.82, P<0.001), ProGRP was higher than that of NSCLC and benign nodules (64.0(40.1, 84.8) vs 38.7(26.9, 47.6), 36.7(29.1, 40.5) ng/L; H values: 36.13, 43.96, P values: 0.002, 0.001) and NSE was higher than that of benign nodules (12.4(10.9, 14.5) vs 7.4(5.4, 11.8) μg/L; H=40.53, P=0.001). When differentiated SCLC from NSCLC, spiculation sign (odds ratio ( OR)=0.043, 95% CI: 0.004-0.450, P=0.009) and ProGRP ( OR=1.083, 95% CI: 1.035-1.133, P<0.001) were independent risk factors for SCLC, and the AUC of the two factors combination was 0.875, with the sensitivity and specificity of 14/18 and 84.2%(80/95). When differentiated SCLC from benign nodules, SUV max( OR=2.706, 95% CI: 1.099-6.662, P=0.030), ProGRP ( OR=1.165, 95% CI: 1.009-1.344, P=0.038) and NSE ( OR=1.639, 95% CI: 1.016-2.645, P=0.043) were independent risk factors for SCLC, and the AUC of the three factors combination was 0.985, with the sensitivity and specificity of 17/18 and 96.7%(29/30). Conclusion:18F-FDG PET/CT combined with tumor markers ProGRP and NSE is helpful to improve the diagnosis and differential diagnosis of stage ⅠA SCLC.

A multicenter survey of antibiotic use in very and extremely low birth weight infants in Hunan Province / 中国当代儿科杂志

OBJECTIVE@#To investigate the current status of antibiotic use for very and extremely low birth weight (VLBW/ELBW) infants in neonatal intensive care units (NICUs) of Hunan Province.@*METHODS@#The use of antibiotics was investigated in multiple level 3 NICUs of Hunan Province for VLBW and ELBW infants born between January, 2017 and December, 2017.@*RESULTS@#The clinical data of 1 442 VLBW/ELBW infants were collected from 24 NICUs in 2017. The median antibiotic use duration was 17 days (range: 0-86 days), accounting for 53.0% of the total length of hospital stay. The highest duration of antibiotic use was up to 91.4% of the total length of hospital stay, with the lowest at 14.6%. In 16 out of 24 NICUs, the antibiotic use duration was accounted for more than 50.0% of the hospitalization days. There were 113 cases with positive bacterial culture grown in blood or cerebrospinal fluid, making the positive rate of overall bacterial culture as 7.84%. The positive rate of bacterial culture in different NICUs was significantly different from 0% to 14.9%. The common isolated bacterial pathogens Klebsiella pneumoniae was 29 cases (25.7%); Escherichia coli 12 cases (10.6%); Staphylococcus aureus 3 cases (2.7%). The most commonly used antibiotics were third-generation of cephalosporins, accounting for 41.00% of the total antibiotics, followed by penicillins, accounting for 32.10%, and followed by carbapenems, accounting for 13.15%. The proportion of antibiotic use time was negatively correlated with birth weight Z-score and the change in weight Z-score between birth and hospital discharge (r=-0.095, -0.151 respectively, P<0.01), positively correlated with death/withdrawal of care (r=0.196, P<0.01).@*CONCLUSIONS@#Antibiotics used for VLBW/ELBW infants in NICUs of Hunan Province are obviously prolonged in many NICUs. The proportion of routine use of third-generation of cephalosporins and carbapenems antibiotics is high among the NICUs.

Diagnostic value of 18F-FDG PET/CT combined with integrated contrast-enhanced CT for hepatic epithelioid hemangioendothelioma / 中华核医学与分子影像杂志

Objective:To explore the value of 18F-fluorodexyglucose (FDG) PET/CT combined with integrated contrast-enhanced CT on the diagnosis of hepatic epithelioid hemangioendothelioma(HEH). Methods:Six patients (2 males, 4 females, age: (41.0±5.6) years) histopathologically confirmed to be HEH in Qingdao Central Hospital between November 2013 and November 2018 were retrospectively analyzed. All patients underwent 18F-FDG PET/CT dual-phase imaging and three-phase dynamic enhanced scanning with integrated CT. Characteristics of 18F-FDG PET/CT and contrast-enhanced CT images were classified and analyzed. Results:All 6 patients had multi-lesions (30 lesions in total). The capsule retraction sign was found in 16.7% (5/30) lesions, target sign was found in 33.3% (10/30) lesions, and " lollipop sign" was found in 13.3% (4/30) lesions. There were three ways of enhancement showed by CT: mild progressive enhancement, delayed enhancement, and black target sign/white target sign in the portal phase. Among the 30 lesions, 66.7% (20/30) had higher 18F-FDG uptake than liver parenchyma, with maximum standardized uptake value (SUV max) of 4.18±0.64 during routine imaging and 4.23±0.70 during delayed imaging, and the retention index was 0.65(-1.88, 4.60). The rest 33.3% (10/30) showed similar 18F-FDG uptake to liver parenchyma, with SUV max of 2.75±0.52 during routine imaging, and 2.78±0.55 during delayed imaging. The uptake of 18F-FDG increased with time in 22 lesions and decreased in 8 lesions. In the metabolically heterogeneous lesions, the relatively high-metabolization site was also the site with higher peak enhancement; in the lesions with uniform metabolism, the CT enhancement was also uniform. Bilateral pulmonary metastases were found in 2/6 patients. Conclusion:18F-FDG PET/CT dual-phase imaging combined with CT three-phase dynamic enhanced scanning is helpful in accurate diagnosis of HEH and could show extrahepatic metastases.

The preoperative scoring system for high-risk gastric stromal tumors / 中华消化内镜杂志

Objective:To explore a scoring system of preoperative evaluation for high-risk gastric stromal tumors.Methods:A total of 275 consecutive patients with gastric stromal tumors of diameter ≤5 cm who underwent surgical or endoscopic resection at Xijing Hospital between 2008 and 2018 were retrospectively enrolled in the study. Multivariate logistic regression analysis was performed to investigate independent risk factors for high-risk gastric stromal tumors.Weighted points was proportionally assigned based on β regression coefficient value to establish the scoring system. The receiver operator characteristic (ROC) curve was plotted, the scoring system as the test variable, and the area under curve (AUC) was calculated.Results:Multivariate analysis revealed tumor size>1.75 cm ( OR=6.474, 95% CI: 2.335-17.948), irregular tumor shape ( OR=3.548, 95% CI: 1.745-7.216) and mucosal ulceration ( OR=2.412, 95% CI: 1.154-5.041) were independent risk factors for high-risk gastric stromal tumors of diameter ≤5 cm ( P<0.05). These risk factors for high-risk gastric stromal tumors were weighted with value: one point for mucosal ulceration, two points for irregular tumor shape and three points for tumor size>1.75 cm. The AUC value of the scoring system was 0.781, of which the cut-off value was 4. According to the cut-off value, 0-3 points was categorized as the low risk group and 4-6 points as the high risk group for gastric stromal tumors. The incidence of high-risk gastric stromal tumors of the low risk group and the high risk group were 13.3% (26/196) and 48.1% (38/79), respectively, with significant difference ( χ2=38.266, P<0.001). Conclusion:Tumor size larger than 1.75 cm, irregular tumor shape and mucosal ulceration can be applied to establish a preoperative scoring system to predict high-risk gastric stromal tumors of diameter ≤5 cm.

Inhibitory Effect of Histone Deacetylase Inhibitor SAHA on Proliferation of Mouse Multiple Myeloma Cell Line SP2/0 in vitro and in vivo / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To explore the anti-myeloma effect of suberoylanilide hydroxamic acid (SAHA) and on mouse myeloma cell line SP2/0 in vitro and in vivo and its mechanism.</p><p><b>METHODS</b>The inhibitory effect of SAHA on SP2/0 cells was measured by CCK-8 assay,and the apoptosis and cell cycle were analyzed by flow cytometry FACS. The protein expression of Caspase-3 and p53 of SP2/0 cells treated with SAHA were examined by Western blot. Annexin V/7-AAD double staining was performed to detect the apoptosis of SP2/0 induced by SAHA in vitro. SP2/0 cells (1×10) resuspended in 200 µl PBS were inoculated subcutaneously and intravenously into BALB/c mice, so as to establish aggressive or non-aggressive myeloma-bearing mouse models respectively. On day 3 after modeling, mice received SAHA or vehicle control treatment by intraperitoneal injection. The dose of SAHA was 60 mg/kg·d, 5 times a week for 3 weeks.</p><p><b>RESULTS</b>In SAHA-treated SP2/0 cells, the proliferation inhibition rate and apoptotic cells increased in a dose dependent manner. Also, SAHA significantly increased the ratio of cells in G phase and decreased in S phase. Molecular mechanisms of apoptosis and cell cycle arrest of SP2/0 induced by SAHA partly correlated with up-regulating the expression level of Caspase-3 and p53. In the non-aggressive myeloma-bearing mice, SP2/0 cells disappeared in peripheral blood after SAHA treatment. In the aggressive myeloma-bearing mice, inhibition of tumor growth and prolongation of the cell survival were observed after SAHA treatment.</p><p><b>CONCLUSION</b>SAHA inhibited SP2/0 cell proliferation, this effect associates with inducing apoptosis and cell cycle arrest, the mechanism of SAHA ralates partly with activating Caspase-3 and p53 pathway.</p>

Assessment of volume status in maintenance hemodialysis patients / 上海交通大学学报（医学版）

Objective · To assess volume status in maintenance hemodialysis (MHD) patients.Methods · Body composition analysis was performed on 128 MHD patients from Renji Hospital,Shanghai Jiao Tong University School of Medicine.The volume status was assessed based on body composition data and predialysis systolic blood pressure (preBPsys),edema grade,brain natriuretic peptide (BNP).Patients were divided into hyperhydrated group (percentage of hydration status,HS％＞ 15％) or normohydrated group (HS％ ≤ 15％).Body composition data were compared,including lean tissue index (LTI) and fat tissue index (FTI).The blood pressure,edema grade,serum calcium,serum phosphate,intact parathyroid hormone (iPTH),hemoglobin,albumin,pre-albumin,hypersensitive C-reactive protein (hs-CRP),serum sodium,and urea clearance Kt/V were compared between two groups.Results · Sixtynine patients were normohydrated and preBPsys reached target;10 patients were overhydrated with higher preBPsys;18 patients had overhydration but preBPsys was in target range.Compared to normohydraed group,patients in hyperhydmted group had more obvious edema,higher BNP level,significantly lower LTI,serum albumin and pre-albumin levels,while serum sodium was significantly higher (P＜0.05).Conclusion· Volume status of hemodialysis patients can be objectively and accurately assessed by body composition analysis using bioimpedance technique with blood pressure,edema grade and biochemical parameters.Hyperhydrated patients may have higher serum sodium level,lower serum albumin,lower hemoglobin,and less lean tissue mass concomitantly.Sodium intake control,nutrition status improvement,and anemia correction may be useful to reduce hyperhydration.

Characteristics of autophagy and its effect on cell proliferation in giant cell tumor of bone / 临床与实验病理学杂志

Purpose To investigate the autophagy characteristics of giant cell tumor of bone and its effect on cell proliferation. Methods Giant cell tumors of bone (GCT-0404 cells) were cultured in vitro and treated with serum-starvation, rapamycin and inhibitor chloroquine. Western blot analysis was performed to detect the autophagic markers LC3 and Beclin 1 expression. Immunofluorescence method was used to show intracellular autophagy formation. Inverted microscope was used to observe the cell morphology. CCK-8 assays were used to detect the cell viability. Results Green fluorescent spots that represented the transformation level of LC3-I to LC3-Ⅱ increased significantly (P＜0.05) by serum-starvation, rapamycin and inhibitor chloroquine respectively, but the expression level of Beclin 1 was not raised. In addition, the cell morphology changed significantly, and cell proliferation was inhibited after serum-starvation, and treatment with rapamycin and inhibitor chloroquine (P＜0.05), Conclusion The changes of autophagy caused by serum starvation, rapamycin and inhibitor chloroquine in GCT-0404 cells may be involved in the down-regulation of cell proliferation.

Risk factors influencing operating efficiency of endoscopic submucosal dissection for gastric mucosal lesions / 中华消化内镜杂志

Objective To explore risk factors of influencing operating efficiency of endoscopic submucosal dissection (ESD) for gastric mucosal lesions. Methods The data of 304 cases with gastric mucosal lesion undergoing ESD in Xijing Hospital of Digestive Disease from April 2009 to February 2017 were retrospectively analyzed. The procedure time and complete resection rate ( R0 resection rate ) were regarded as indicators of ESD efficiency. Risk factors influencing procedure time and R0 resection rate were analyzed using Chi-square test and logistic regression. Results Using median procedure time of 45 min as the cutoff value, Chi-square test showed that specimen size ( P=0. 000) , lesion location ( P=0. 001) , and pathological type ( P=0. 003) affected the operation time. Further logistic regression analysis indicated that specimen size (≥40 mm/<40 mm, P<0. 001, OR=3. 748, 95％CI: 2. 247-6. 254) and lesion location (upper or middle 1/3 of stomach/lower 1/3 of stomach, P=0. 001, OR=2. 180, 95％CI: 1. 318-3. 606) were independent risk factors of procedure time. Using R0 resection as outcome measure, neither single nor multiple parameter analysis was statistically significant. Conclusion Specimen size and lesion location are independent risk factors influencing efficiency of gastric mucosal ESD, and could be possibly used to estimate the procedure time of ESD.

Prognostic value of the number of lesions with SUVmax>2.5 and metabolic tumor volume assessed by 18 F-FDG PET/CT imaging in patients with multiple myeloma / 中华核医学与分子影像杂志

Objective To investigate the effective indicators for the prognosis assessment in pa?tients with multiple myeloma (MM) by 18F?FDG PET/CT imaging. Methods A total of 36 patients(22 males, 14 females;median age 63.5 years) with MM confirmed by clinical or pathology from July 2007 to November 2014 were retrospectively reviewed. The number of lesions detected by PET/CT, the number of lesions with SUVmax>2.5, the SUVmax and MTV of each lesion were calculated. The correlation analysis was performed between the number of lesions detected by PET or CT,the number of lesions with SUVmax>2.5, the SUVmax , MTV and serumβ2?microglobulin (β2?M) , respectively. The patients were divided into differ?ent groups according to the development of lesions and the survival situation during the follow?up ( 4-92 months) . Kaplan?Meier analysis and multivariate Cox model were used to analyze the prognostic significance of the number of lesions detected by PET or CT and the number of lesions with SUVmax>2.5, the SUVmax and MTV. Results Both the number of lesions with SUVmax>2. 5 and MTV showed positive correlations with blood β2?M (r=0.776, 0.954, both P0.05) . The number of lesions with SUVmax>2.5 and MTV in the progressive group( n=14) were significantly higher than those in the regressive group(n=22):66.57±4.59 vs 31.95±4.75, t=4.95, P2.5 and MTV were significantly higher in the dead group(n=15) than those in the survival group(n=21):65.73±4.32 vs 30.90±4.87, t=5.10, P2. 5, and those were 114.74 and 105.48 cm3 for MTV, respectively. The progression?free survival rate was worse in the patients with higher index than those with lower value (χ2=18.20, 29.74, both P2.5 and MTV on 18 F?FDG PET/CT images could predict the progression?free survival and overall survival rates of patients with MM, which may provide accurate prognosis information.

Value of delayed PET/CT on diluted and filled bladder for the detection of bladder cancer / 中华核医学与分子影像杂志

Objective To evaluate the value of increased threshold of SUVmax and delayed imaging on diluted and filled bladder for improving the detection of bladder cancer with 18F-FDG PET/CT.Methods From July 2007 to October 2012,18 F-FDG PET/CT was performed on 63 suspected or treated (with bladder preserved) bladder cancer patients (55 males,8 females,average age 69.1 years).After routine imaging,all patients were given 1 500-2 000 ml of water orally three times and voided three times.Then they underwent delayed pelvic imaging at a full bladder status.The routine images were reanalyzed with increased SUVmax threshold (from 6-8 to 8-20).The final diagnosis was confirmed by pathology or follow-up (＞6 months).The differences of SUVmax in urine,18 F-FDG metabolism in lesions between routine and delayed imaging were compared.Paired t test was used to compare their differences.Results The SUVmax of urine on routine and delayed imaging was 15.11±11.11 and 4.73±2.00 respectively (t=4.15,P＜0.01).Among the 63 patients,there were 15 malignant and 3 benign cases confirmed by pathology,and 45 patients without obvious abnormality during follow-up.All 18 cases were detected by 18F-FDG PET/CT including the 3 benign false positive cases (2 were positive by CT though negative by PET,and 1 FDG-avid cystitis).All 15 true positive cases were confirmed as primary or recurrent bladder carcinoma and 1 false positive case as inflammation.The detection rates of early imaging with routine and increased display threshold of SUVmax were 18.8％(3/16) and 43.8％(7/16),respectively.Conclusion Increased SUVmax threshold for display and delayed imaging with diluted urine under full bladder status could effectively improve the detection rate of primary or recurrent bladder cancer with 18F-FDG PET/CT.

Clinical value of (18)F-FDGPET/CT in differentiation between benign lesions and lung cancer for large shadows in patients with pneumoconiosis / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To evaluate the clinical value of (18)F-FDG PET/CT in the differentiation between benign lesions and lung cancer for large shadows in patients with pneumoconiosis.</p><p><b>METHODS</b>A retrospective study was conducted in 21 patients with a confirmed diagnosis of pneumoconiosis who had a total of 37 large shadows in the lung fields as shown by whole-body (18)F-FDG PET/CT imaging, and (18)F-FDG uptake was evaluated using the maximum standardized uptake value (SUVmax). Twelve lesions were examined by CT-guided aspiration biopsy, and one case underwent fiberoptic bronchoscopy, as well as tests based on bronchoalveolar lavage fluid and sputum; the other cases were followed up for more than 2 years. The differences between pneumoconiosis nodules with high (18)F-FDG uptake and lung cancer were evaluated by t test.</p><p><b>RESULTS</b>Seventeen lung masses or nodules with high (18)F-FDG uptake were detected in 13 patients; among the 13 patients, 5 lesions of 5 cases were confirmed as non?small cell lung cancer (1 case of squamous cell carcinoma, 3 cases of adenocarcinoma, and 1 case of recurrent squamous cell carcinoma after operation), and 7 lesions of 7 cases were progressive massive fibrosis as shown by CT-guided aspiration biopsy; one case had no tumor cells detected by fiberoptic bronchoscopy, and 2.5-year follow-up revealed no changes in the lesions. The other 8 patients showed no increased (18)F-FDG uptake in their 20 lung nodules, which were confirmed as benign lesions by follow-up. The diameter range of lung cancer was 1.6∼6.8 cm, and the SUVmax range was 4.8∼14.0; the diameter range of pneumoconiosis nodules with high (18)F-FDG uptake was 1.5∼4.6 cm, and the SUVmax range was 2.6∼12.4. There were no significant differences in diameter and SUVmax between the lung cancer and pneumoconiosis nodules with high (18)F-FDG uptake (P > 0.05 for both). (18)F-FDG PET/CT had a specificity of 62.5% (20/32), an accuracy of 67.6% (25/37), a false-positive rate of 37.5% (12/32), and a negative predictive value of 100% (20/20) for the diagnosis of lung cancer. The lung cancer detection rate was 23.8% (5/21).</p><p><b>CONCLUSION</b>In (18)F-FDG PET/CT imaging for patients with pneumoconiosis, the lung lesions without (18)F-FDG uptake or symmetrical lesions with high (18)F-FDG uptake are considered as benign pneumoconiosis nodules; however, (18)F-FDG PET/CT might have a limited role in evaluating the solitary lung lesions in patients with pneumoconiosis and needs further study.</p>

The value of 18F-FDG PET/CT in transcatheter hepatic arterial chemoembolization therapy of primary hepatocellular carcinoma with high FDG uptake / 中华核医学与分子影像杂志

Objective To evaluate the therapeutic response of transcatheter hepatic arterial chemoembolization (TACE) for primary HCC using 18 F-FDG PET/CT.Methods Twenty-four HCC patients (21males,3 females; age range:40 to 75 years,mean age:58.1 years) with high uptake of 18F-FDG on pretreatment PET/CT and with follow-up 18F-FDG PET/CT 1-2 months post TACE were retrospectively analyzed.A lesion was regarded as positive for HCC if it had higher FDG uptake than the surrounding liver parenchyma.All patients were followed for 3 months by clinical symptoms,AFP and 18F-FDG PET/CT.x2 test was used to analyze the difference between the diagnostic value of 18F-FDG PET/CT and AFP.Results On follow-up 18F-FDG PET/CT,9 patients had lower 18F-FDG uptake than the surrounding liver parenchyma,indicating no residual tumor; while 11 patients with residual tumor showed higher uptake of FDG than the liver background though the uptake was lower than that of baseline PET/CT.Two patients with isometabolic FDG uptake were confirmed of having residual tumor during follow-up.One case showed increased 18F-FDG uptake more than that of baseline,indicating disease progression.One case was false positive for residual tumor due to over attenuation correction in the presence of lipiodol.The sensitivity and accuracy for the detection of residual tumor by 18F-FDG PET/CT and AFP were 100％ (14/14) vs 71.4％ (10/14),and 95.8％(23/24) vs 70.8％(17/24) (x2 =6.56 and 4.18,both P＜0.05),respectively.Conclusion 18F-FDG PET/CT is useful to evaluate the efficacy of TACE for 18F-FDG-avid HCC and it may provide important information for further treatment planning.

Objective To evaluate the value and characteristics of 18F-FDG PET/CT and contrastenhanced CT in pulmonary sclerosing hemangioma (PSH).Methods A retrospective study involving 5 patients confirmed as PSH by pathology from June 2007 to June 2011 was performed.The cases consisted of four women and one man with age ranged from 39 to 66 (mean 51.6) years.All patients received dualphase 18 F-FDG PET/CT,high resolution (HR) CT and multi-phase contrast-enhanced CT (Siemens Biograph 16 PET/CT).Lesion SUVmaon early and delayed PET/CT images,retention index,increased HU value,washout time from peak on contrast-enhanced CT and peritumor vessel sign were studied.Results PSH lesions showed patchy increased 18F-FDG uptake with mean SUVmax on early and delayed PET/CT of 3.3 ± 1.1 and 3.4 ± 1.4,respectively.The mean retention index was (2.1 ± 20.8) ％.The morphological features of PSH on HRCT included findings such as a round/oval nodule or mass with well-defined margins and air meniscus sign.On muhi-phase contrast-enhanced CT,PSH showed moderate to high enhancement (the increased value:35 to 59 HU) with washout times from peak of 140 to 260 s,and 1 to 4 peritumor vessel signs.Conclusions A patchy pattern of high 18F-FDG uptake on PET/CT is suggestive of benign entity.Contrast-enhanced CT findings are very useful to increase the confidence for the diagnosis of PSH.

Changes of immunologic parameters in patients with simple bone metastases treated with 89SrCl2 / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the influence of (89)SrCl(2) (strontium-89 chloride) on immune functions in patients with simple bone metastases.</p><p><b>METHODS</b>Twenty-five patients diagnosed as simple bone metastases with un-detectable primary tumors were treated with (89)SrCl(2). The CD4(+), CD8(+), CD4(+)/CD8(+) lymphocyte subsets were assessed before and after (89)SrCl(2) treatment. Twenty normal individuals served as controls.</p><p><b>RESULTS</b>The CD4(+), CD8(+) and CD4(+)/CD8(+) in the control group were (38.83 +/- 8.95)%, (32.19 +/- 8.51)% and 1.29 +/- 0.47, respectively. In patients, they were (31.12 +/- 8.12)%, (41.75 +/- 10.91)% and 0.84 +/- 0.22 before treatment, and (36.21 +/- 8.71)%, (35.08 +/- 10.14)% and 1.19 +/- 0.27 after treatment, respectively (P < 0.05). The patients were divided into treatment effective and non-effective groups by pain score. Before treatment, the immunologic parameters in the two groups had no significant differences (P > 0.05). After treatment, the frequencies of CD4(+) and CD8(+) subsets, CD4(+) to CD8(+) ratios and the number of metastatic foci in the effective group were (37.81 +/- 5.18)%, (33.17 +/- 6.38)%, 1.33 +/- 0.31 and 6.64 +/- 3.11, respectively, while in the treatment non-effective group, they were (32.09 +/- 5.72)%, (39.99 +/- 5.38)%, 0.82 +/- 0.22 and 9.87 +/- 3.46, respectively (P < 0.05).</p><p><b>CONCLUSION</b>The immune functions in patients with simple bone metastases are inhibited. Treatment with (89)SrCl(2) may improve their immunity to certain extent. The degree of recovery in the treatment effective patients was better than that in the treatment non-effective cases.</p>

Effects of genistein and 17?-estradiol on microstructure of cancellous bone in ovariectomized rats / 中华内分泌代谢杂志

Objective To observe the effects of genistein and 17?-estradiol on microstructure of cancellous bone in ovariectomized (OVX) rats.Methods Ninty 7-month-old SD rats were randomly divided into baseline group,ovariectomized (OVX),sham-operated (SHAM),17?-estradiol treated (10?g?kg~(-1).day~(-1),EST) and genistein treated (5 mg?kg~(-1)?day~(-1),GEN) groups,and were killed at the beginning of the experiment,the 3rd and 15th week after operation.MicroCT scanning was performed on the left tibia in vitro.The regions involving 0.5 mm slice thickness and 1.6 mm distal to the tibial growth plate were selected as the regions of interest.Results At the 3rd week after operation,the tissue bone mineral density (tBMD) and trabecular thickness (sTh.Th) in group GEN were significantly higher than those in OVX and EST groups (all P

Effects of triazole schiff base derivative on the differentiation and apoptosis of human hepatocarcinoma cells / 中国药理学通报

Aim To study the effect of 3-pyridin-3-yl-4-[(4-hydroxy-3-methoxy-benzylidene)amino]-5-me-thylsulfanyl-4H-[1,2,4] triazole (LH-37) on induction of differentiation and apoptosis of hepatocarcinoma BEL-7402 cells. Methods BEL-7402 cells were cultured in RPMI 1640 and treated by LH-37 at different doses. The proliferation of the cells and the inhibition effect of LH-37 on the cell proliferation were examined by MTT assay. The reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the changes of alpha fetoprotein(?-FP)mRNA and albumin(Alb). The concentration of ?-FP in the cells was detected by ELISA assay. Cell morphology was observed by fluorescence microscope techniques. The protein expressions of active caspase-3 in BEL-7402 cells were observed by immunohistochemical staining. Western blot was used to assay caspase-3 and caspase-9. Colorimetric method was used to assay activity of superoxide dismutase (SOD) and catalase (CAT). The apoptotic cells were assayed by flow cytometry (FCM) with annexin V-FITC conjugated and propidium iodide (PI) staining. Results The cell proliferation was inhibited by LH-37 at 10 ?mol?L-1~1 mmol?L-1 in dose dependent manners. After treated with 10 ?mol?L-1 or 1.0 ?mol?L-1 LH-37, the mRNA and protein expression of ?-FP were significantly reduced but mRNA expression of Alb was significantly increased. Treatment of BEL-7402 cells with different LH-37 concentrations for 48 hours increased the percentage of active caspase-3 positive cells and protein expression of caspase-3 and caspase-9. More apoptosis features of cells were observed in LH-37 ( 100 ?mol?L-1) treatment groups than in control group. LH-37 markedly promoted the viability of SOD and decreased CAT in BEL-7402 cells. Counclusion LH-37 might inhibit proliferation and induce differentiation and apoptosis of human hepatocarcinoma BEL-7402 cells, which might be related to the cytotoxicity of the intracellular hydrogen peroxide (H2O2).
