OBJECTIVE:To investigate the characteristic and regularity of antineoplastics-induced ADR,and to provide refer-ence for safety use of antineoplastics in clinic. METHODS:In retrospective study,309 cases of antineoplastics-induced ADR col-lected from a special hospital during Jan.-Dec. 2015 were summarized and analyzed statistically. RESULTS:Among 309 ADR cas-es,female (58.25％) was more than male (41.75％). The patients aged more than 40 years old occupied the highest proportion (78.64％). Main route of administration was intravenous dripping(94.82％). There were 225 cases of severe ADR(72.82％). To-tal 268 cases were improved after drug withdrawal or treatment(86.73％). A total of 24 kinds of antineoplastics were involved in 309 ADR cases;most of ADR were induced by docetaxel,followed by cisplatin,cyclophosphamide. Most common organs/system involved in ADR was hemopoietic system (64.24％),main clinical manifestation was myelosuppression. CONCLUSIONS:It is necessary to strengthen ADR monitoring,prevent,discover and treat antineoplastics-induced ADR timely,in order to reduce the harm to the patients and ensure the safety and effectiveness of drug treatment.

Background During the past two decades, a number of rating scales were developed to facilitate diagnosis and assessment of subjects with social anxiety disorder. One of the most commonly used scales for the assessment of social anxiety disorder is the Liebowitz social anxiety scale (LSAS). The LSAS is widely used in epidemiologic investigations and clinical researches,and its assessment in the pharmacotherapy efficacy for social anxiety disorder is superior to any other scale. So we designed this study to explore the validity and reliability of the LSAS in Chinese patients with social anxiety disorder and normal control, and to find the difference of the scores between the patients self -report version and clinician-administered version. Methods Fifty five patients meeting the DSM-Ⅳ diagnostic criteria for social anxiety disorder and 168 normal controls who were screened from 222 college students were rated by LSAS, social phobia scale and self-made General Information Forms. Results The Cronbath α of LSAS for the patients and the normal controls was 0.83 and 0.77, respectively. The 4-week test-retest reliability for total scores and its factors scores of LSAS in 31 normal controls were ranging from 0.68 to 0.79. The ROC area under curve value in discriminating the patients from normal controls was 0.87±0.03; the total score of 35 was considered to be the best cut-off score for LSAS, then its sensitivity was 0.77 and its specificity was 0.81; and no significant difference between the self-report version and clinician-administered version. Conclusions The LSAS is good in internal consistency and test-retest reliability, and has high sensitivity and specificity in discriminating the patients and the controls. There is no significant difference in the total score and each factor scores of LSAS between self-report version and clinician-administered version.

Abstract: To report a case of Aspergillus salwaensis-induced spinal infection and its laboratory detection. The inflammatory granulation and necrotic tissue samples of a patient with spinal infection were collected from, the Affiliated Hospital of Chengde Medical College on June 17, 2020 for direct smear microscopy and culture, and the isolated strain was identified by microscopy by smear staining, matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS), molecular identification and in vitro antifungal susceptibility test. The patient was 62 years old female and presented with recurrent chest and back pain with no obvious cause. The initial diagnosis was spinal infection, after 7 days of treatment with levofloxacin, the effect was not good. Surgery was then performed remove the lesion via posterior thoracic debridement, and fungal hypha was observed under microscope in tissue specimens. The isolated strains had no typical structure, MALDI-TOF-MS was used for identification for many times, but there was no identification result. After 7 days of fluconazole treatment, the patient's condition improved, and her chest and back pain were alleviated compared to before surgery. The patient was discharged and followed up in the outpatient department, the fungus was later identified as Aspergillus salwaensis by sequence analysis of the internal transcribed spacer (ITS) gene sequencing, and the patient's antifungal medication was changed to voriconazole after with the attending physician. The patient consciously recovered well with no pain in the operative area and normal spinal activity at 1 year follow-up. The possibility of spinal fungal infection should be considered in patients with back pain without a clear cause and poor response to routine antibiotic treatment. Direct smear report of microscopic results are very important for guiding clinical antibiotic selection for rare filament fungi with atypical colony and microscopic morphology and unsuccessful MALDI-TOF-MS identification, molecular biological methods such as ITS sequence analysis can be helpful for early identification of the fungal species, improving identification speed.

OBJECTIVETo explore the effect of berberine on lipid metabolism disorder and lipid deposition in liver cells of non-alcoholic fatty liver disease (NAFLD) rats induced by high fat diet.

METHODSAfter one week adaptable feeding, 45 SPF level male SD rats were randomly divided into 3 groups, the normal control group, the model group, and the berberine group, 15 in each group. Except those in the normal control group, all rats were fed with high fat diet to prepare NAFLD model. As for rats in the berberine group, Berberine Hydrochloride was administered by gastrogavage. HE staining and oil red O staining were performed to identify the model after 8 weeks. Hepatocytes were isolated, and their activities and purities were tested by Typan blue staining and flow cytometry (FCM). Serum levels of TC, TG, HDL-C, and LDL-C were detected using automatic biochemical analyzer. mRNA expression levels of LXRα and FAS in liver cells were analyzed by Real-time quantitative polymerase chain reaction (PCR). Protein levels of LXRα and FAS in liver cells were examined by Western blot.

RESULTSThe NAFLD rat model was successfully established by high fat diet. The yields of purified liver cells in each rat were (6.0-7.5) x 10(8). The viability of isolated liver cells with purity over 90% (tested by FCM analysis) was higher than 95%. Compared with the normal control group,the expression of LXRα and FAS at mRNA and protein levels was higher in the model group (P < 0.01). Compared with the model group, the expression of LXRα and FAS at mRNA and protein levels was obviously down-regulated in the berberine group (P < 0.01).

CONCLUSIONSLXRα/FAS signaling pathway was one of important signaling pathways of NAFLD lipid metabolism disorders. Berberine could recover hepatocyte fatty deposits in NAFLD rats by adjusting the LXR/FAS signaling pathway of hepatocytes, which might be one of important mechanisms for fighting against NAFLD.

OBJECTIVETo study the effect of osthole (Ost) on adrenocortical function in Y1 mouse adrenocortical tumor cells.

METHODSY1 mouse adrenocortical tumor cells were taken as subjects in this experiment. In 10.0%, 1.0%, and 0.1% serum DMEM-F12 medium, Y1 cells were treated with 1, 10, 25, 50, 100, and 200 micromol/L Ost for 24 and 48 h. 0.1% Dimethyl Sulfoxide (DMSO) was taken as negative control group and 1 mmol/L (Bu) 2cAMP as positive control group. Cell growth morphology was observed under inverted microscope. Contents of corticosterone were tested by ELISA. Expression levels of steroids synthase such as Star, Cyp11a1, Cyp21a1, Hsd3b2, Cyp11b1, Cyp11b2, Cyp17a1, and Hsd17b3 mRNA were detected by Real time quantitative PCR (RT-qPCR).

RESULTSY1 cell proliferation was obviously inhibited by 100 and 200 micromol/L Ost, and its inhibitory effect was more significant in 0.1% serum medium. Compared with the negative control group, gene expressions of Star, Cyp11a1 , Cyp21a1, Hsd3b2, Cyp11b1, Cyp17a1, and Hsd17b3 were significantly enhanced in the posi- tive control group (P < 0.05). Y1 cell corticosterone levels significantly increased in 50 micromol/L Ost treatment group after 24-and 48-h intervention (P < 0.05). Contents of corticosterone increased more obviously in 25 and 50 +/- mol/L Ost treatment groups after 48-h intervention, as compared with 24-h intervention (P < 0.01). After 24-h intervention, expression levels of Star, Cyp21a1, and Hsd3b2 genes were significantly up-regulated in 25 and 50 lLmol/L Ost groups (P < 0.05). Star gene expression was further enhanced after 48-h intervention (P < 0.05). However, Ost showed no effect on Cyp11a1 (P > 0.05). Additionally, gene expressions of Cyp11b1 and Cyp17a1 were significantly enhanced by 10, 25, and 50 pLmolIL Ost after treatment for 24 and 48 h (P < 0.05). Ost showed no obvious effect on Cyp11b2 and Hsd17b3 expressions.

CONCLUSIONOst could regulate adrenal cortex function and promote corticosterone synthesis and secretion through strengthening gene expressions of steroidogenic enzymes.

OBJECTIVETo investigate the effects of non-neuronal muscarinic receptors (NNMR) stimulation on atherosclerosis and endothelial cells activation.

METHODSAtherosclerosis model was established in ApoE-/- mice by a high fat diet for 7 weeks. During the experimental periods, animals were received a low (7 mg/kg/d) or a high (21 mg/kg/d) dose of arecoline by gavage. At the termination of the treatments, serum total cholesterol and NO levels were measured, and the aorta morphology was analyzed by hematoxylin and eosin staining. The gene expression of monocyte chemoattractant protein-1 (MCP-1) and adhesion molecules in the thoracic aortas was determined by RT-PCR, and the MCP-1 protein expression and NF-κB activity were detected by Western blot analysis. NO production, MCP-1 secretion in cultured rat aortic endothelial cells (RAECs), and monocyte-endothelium adhesion assay were also performed after arecoline treatments.

RESULTSArecoline efficiently decreased atherosclerotic plaque areas, increased serum nitric oxide (NO) content, suppressed the mRNA and protein expression of MCP-1, and modulated the IκB-α degradation and P65 phosphorylation in the aortae of ApoE-/- mice. Furthermore, arecoline promoted NO production and suppressed MCP-1 secretion in cultured RAECs after ox-LDL exposure, and either atropine or NG-nitro-L-arginine methylester could abrogate these effects. Arecoline also significantly inhibited the adherence of U937 monocytes to the ox-LDL injured human umbilical vein endothelial cells, which could be abolished by atropine.

CONCLUSIONOur results indicate that arecoline attenuates the progression of atherosclerosis and inhibits endothelial cells activation and adherence by stimulating endothelial NNMR. These effects, at least in part, are due to its modulation on NF-κB activity.

BACKGROUND:It is important to maintain the height of joint line in total knee arthroplasty or renovation. Foreign scholars have reported the parameters of the distance from different landmarks to knee joint line, but there is stil a lack of relevant data for Chinese people. OBJECTIVE:To explore the relationships of the knee anatomic landmarks and joint line in normal Chinese, thereby providing clinical evidence for primary total knee replacement and knee renovation. METHODS:Totaly 746 normal knee joints of 409 healthy volunteers from North China and Southwest China were randomly enroled, including 214 males and 195 females, with a mean age of 37.7 years. CT scan was used to reconstruct the three-dimensional knee joint, and the distance between the anatomic landmarks and the joint line was measured using Mimics software. RESULTS AND CONCLUSION:The distance from the center of femoral medial sulcus to the joint line was (25.72±2.52) mm. The distance from the center of lateral femoral condyle prominence to the joint line was (26.30±2.65) mm. The distance from the adduction muscle tubercle to the joint line was (44.60±4.32) mm. The distance from the peak of the tibial tubercle to the joint line was (21.50±3.57) mm. These parameters in male group were significantly higher than those in female group (P < 0.05). In conclusion, these findings provide anatomic evidence for the recovery of joint line in knee replacement or renovation; the variability of the distance from the center of femoral medial sulcus, lateral femoral condyle prominence and adductor tubercle to the joint line is smaler, and therefore, these landmarks have more reference values in total knee arthroplasty.
