OBJECTIVETo find a method without corticosteroids, aspirin or heparin for treatment of anticardiolipin antibody-positive early recurrent spontaneous abortion (AARSA).

METHODSTwenty-three patients of AARSA in the treated group were treated with Chinese herbal medicine (CHM) plus human chorionic gonadotropin and progesterone, and 18 patiens in the control group were treated with multi-vitamin only. The change of anticardiolipin antibody was determined by enzyme linked immunoabsorbent assay (ELISA).

RESULTSAfter treatment, anticardiolipin antibody negative converted in 20 cases (86.9%) of the treated group. The cure rate of abortion in the treated group was 82.6% (19/23), which was raised to 95% (19/20) in those patients with antibody negative conversion, while in the control group, it was 16.7% (3/18) merely, comparison between the two groups in cure rate showed significant difference (P < 0.01).

CONCLUSIONCHM plus human chorionic gonadotropin and progesterone could cure AARSA effectively.

OBJECTIVETo investigate the relationship between genetic variantions of circadian clock genes and risk of breast cancer.

METHODSA case-control study including 406 breast cancer patients and 412 controls was conducted and genes Clock (rs2070062) and Per2 (rs2304672, rs2304669, rs934945) were genotyped by TaqMan real-time PCR. Unconditional logistic regression model was used to analyze the association between the genetic polymorphisms and breast cancer.

RESULTSIndividuals with the rs2304669-TT genotype showed significantly increased breast cancer risk with the OR of 2.33 when compared with the individuals with rs2304669-CC and CT genotypes (P = 0.001). In addition, the three haplotypes containing the risk T allele of rs2304669 were identified to be associated with increased breast cancer risk. However, it was found that rs2304672, rs2070062 and rs934945 polymorphisms were not related with breast cancer risk.

CONCLUSIONSThe locus rs2304669 on Per2 gene is associated with breast cancer risk. Genetic variation of circadian clock genes may increase the susceptibility to breast cancer. Therefore, it may become an important biomarker of susceptibility to breast cancer.

OBJECTIVETo investigate the relationship between plasma cytochrome P450 3A4 (CYP3A4) 894C>T gene polymorphism and the risk of recurrence of adverse cardiac events after percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS).

METHODSA total of 275 patients with ACS received standard dual antiplatelet therapy and PCI. Platelet aggregation rate (PAR) was detected in each patient before and 7 days after administration of the anti-platelet drugs. Single nucleotide polymorphism of CYP3A4 gene 894C>T was detected with PCR and microarray technique. The number of coronary artery lesions was determined by PCI and the Gensini score was calculated. The patients were followed up for 3-12 months after discharge.

RESULTSNo significant difference was found in CYP3A4 gene polymorphism between patients with clopidogrel resistance (CR group) and those without CR (NCR group) (P>0.05). Multivariate logistic regression analysis showed that CYP3A4 gene 894C>T polymorphism was not correlated with CR in patients with ACS (OR 1.359, P>0.05). During the follow-up, the incidence of cardiovascular events was significantly higher in CR group than in NCR group (P<0.05), but this difference was not related to the mutation type of 894C>T locus of CYP3A4 gene.

CONCLUSIONThe CYP3A4 gene 894C>T polymorphism is not associated with the effect of anti-platelet therapy and the risk of cardiovascular event in patients with ACS following PCI.

OBJECTIVETo explore the relationship between polymorphisms of FAS and FASL genes and genetic susceptibility of silicosis.

METHODSA case-control study was conducted. The case group was 183 male patients with silicosis and the control group was 111 male silica-exposed but without silicosis miners. Data on total dust concentrations was collected to estimate cumulative total dust exposure (CTE) of each subject and each person's characteristics and work history were obtained from questionnaire. Polymerase chain reaction re-strained fragment length polymorphism technique (PCR-RFLP) was applied to detect the single nucleotide polymorphisms (SNPs) of FAS-1377, FAS-670 and FASL-844. Associations between polymorphisms and risk of silicosis and stages, interactions between polymorphisms, between polymorphisms and CTE and smoking and haplotypes were analyzed.

RESULTSThere were no differences in the FAS-1377, FAS-670 and FASL-844 genotypes between the case group and the control group (P > 0.05). No association was observed between FAS-1377, FAS-670 and FASL-844 polymorphisms and silicosis and stages (P > 0.05). The frequencies of FAS-1377G/-670G haplotype in the cases (9.6%) were higher than those in the controls (3.6%) (P < 0.05). No interactions between the polymorphisms of different genes, the gene polymorphism and the total accumulative total dust, the gene polymorphism and smoking were observed (P > 0.05).

CONCLUSIONFAS-1377, FAS-670 and FASL-844 polymorphisms are not susceptible factors of silicosis. The FAS-1377G/-670G haplotype might be a susceptibility marker of silicosis.

OBJECTIVETriple-negative [estrogen receptor (ER)-/progesterone receptor (PR)-/HER2-] breast cancer (TNBC) accounts for ∼ 15% of overall breast cancer and associated with a poor prognosis. There is a short of standard adjuvant chemotherapy regimens for TNBC. A number of studies have shown that TNBC might be sensitive to cisplatin and carboplatin on the basis that dysfunction of BRCA1 and its pathway is associated with a specific DNA-repair defect, but data of adjuvant setting about this is limited.

METHODSFrom January 2010 to September 2011, 95 early triple-negative breast cancer patients confirmed by pathology were randomly assigned to receive TP (docetaxel 75 mg/m², carboplatin AUC = 5, day 1, 21 days a cycle for 6 cycles) or EC-T (epirubicin 90 mg/m², cyclophosphamide 600 mg/m², d1, 21 days a cycle for 4 cycles, followed by docetaxel 80 mg/m², d1, 21 days a cycle for 4 cycles) chemotherapy. Adjuvant radiation therapy was given selectively after chemotherapy. Here we report a preliminary safety analysis with the chi-square test.

RESULTSSeventy-six out of the 95 patients had completed the chemotherapy and could be assessed for the safety profiles of the regimens. Thirty-seven of them were in the EC-T group with a median age of 47 years, and 21 out of these 37 patients were premenopausal (56.8%). Another 39 patients came from the TP group with a median age of 46 years, and 22 out of these 39 patients were premenopausal (56.4%). All of the 37 patients in EC-T group completed the planned treatment whereas 2 patients of the 39 cases in TP group did not because of bone marrow suppression. During the treatments, 9 patients had dose adjustment in each group. Adverse events of grade 1/2 were common. Specific incidence of adverse events with grade 3/4 in each group was as follows: alopecia, 29.7% vs. 10.3% (P = 0.033), vomiting 21.6% vs. 7.7% (P = 0.085), leukopenia 54.1% vs.25.6% (P = 0.011) and neutropenia 51.4% vs. 35.9% (P = 0.174). Other grade 3/4 toxicities were rare. All the adverse events (except peripheral neuropathy and pigmentation) recovered within 1 month after the chemotherapy.

CONCLUSIONBoth EC-T and TP regimens as adjuvant chemotherapy are safe and tolerable for the treatment of triple-negative breast cancer patients, while the TP regimen has advantages with less grade III/IV alopecia and leukopenia.

OBJECTIVETo investigate the correlation between a diverse of clinical factors and bone metastases of prostate cancer.

METHODSThe clinical data of 80 patients with prostate cancer were collected and analyzed. The correlations of age, alkaline phosphotase (ALP), prostate specific antigen (PSA), erythrocyte sedimentation rate (ESR), Gleason score, and expressions of androgen receptor (AR) and Ki-67 with bone metastases were analyzed by one-way ANOVA and Logistic regression analysis. The cutoff value, sensitivity and specificity of the independent correlation factors were calculated.

RESULTSForty-five of the 80 patients (56%) were found to have bone metastasis, who had significantly older age and higher levels of ALP, PSA, ESR, Gleason score, and expressions of AR and Ki-67 than those without bone metastasis (P<0.05). Logistic regression analysis identified PSA, Gleason score and AR expression as independent factors correlated with bone metastasis with OR (95% CI) of 1.005 (1.001, 1.009) (P=0.008), 5.356 (1.431, 20.039) (P=0.013), and 18.594 (2.460, 140.524) (P=0.005), respectively. The cutoff values of PSA, Gleason Score and AR were 67.1 ng/ml, 7.5, and 2.5, respectively; their sensitivities were 55.6%, 75.6%, and 84.0% for predicting bone metastasis with specificities of 97.1%, 82.9%, and 91.4%, respectively.

CONCLUSIONOf the factors analyzed, PSA, Gleason score and AR expression, but not age, ALP, PSA, ESR, or Ki-67 expression, are the predictive factors of bone metastasis of prostate cancer.

OBJECTIVETo explore the effects of simvastatin on vascular endothelial cell apoptosis and Bcl-2 protein expression in the aorta in a rat model of atherosclerosis.

METHODSThirty-six rats were randomized into control group (n=10), atherosclerosis model group (n=13) and simvastatin intervention group (n=13). In the latter two groups, rat models of atherosclerosis were established by intraperitoneal injection of vitamin D3 combined with high-fat feeding for 6 weeks, and the control rats were fed with regular diet. In the intervention group, the rats were further fed with high-fat diet with daily simvastatin treatment for 4 weeks. After the treatments, the pathological changes and plaque in the thoracic aorta were observed, and the expression of Bcl-2 protein was detected with immunohistochemistry. TUNEL assay was used to determine the apoptosis index (AI) of the vascular endothelial cells.

RESULTSCompared with that in the control group, Bcl-2 protein expression in the aorta of atherosclerotic rats was significantly decreased (P<0.05); simvastatin treatment obviously increased the expression of Bcl-2 protein in atherosclerotic rats (P<0.05) to a level similar to that in the control group. The AI was the highest in the model group (P<0.05) and comparable between the control and simvastatin treatment group.

CONCLUSIONThe therapeutic effect of simvastatin against atherosclerosis is probably mediated by up-regulation of Bcl-2 protein, which inhibits vascular endothelial cell apoptosis in rats with aortic atherosclerosis.

Objective To study the effects of atherosclerotic high-fat diet on body weight, blood glucose, blood lipid levels and atherosclerotic plaque formation in mice, and to determine the effect of fasting time on the results of blood lipid testing. Methods 10-week-old male ApoE knockout (ApoE^-/-) mice were given high-fat diet and normal diet. The atherosclerotic plaques were observed four months later. 10 week old C57BL/6J male mice were given regular diet for 4 weeks, regular diet for 2 weeks + high-fat diet for two or four weeks. Body weight、liver、glucose, and the serum lipid levels were examined. The influence of fasting for 12 h, 6 h or no fasting on blood lipid detection results before sacrificing were studied. Results The atherosclerotic plaque area of ApoE^-/- mice given high-fat diet increased significantly (P<0.01). C57BL/6J mice given high-fat diet gained weight (P<0.01). The glucose, TC, LDL-c and HDL-c were also increased in C57BL/6J mice with liver fat accumulation while the level of TG was significantly decreased(P<0.01). Compared with the fasting 12 h group, serum triglyceride (TG) was significantly increased (P<0.01）in fasting 6 h and no fasting groups. Conclusion The atherosclerotic high-fat diet can accelerate the formation of atherosclerotic plaques in ApoE^-/- mice, significantly increase blood sugar, TC and LDL-c levels, but significantly reduce TG values.. The fasting time can affect serum triglyceride (TG) level.

Objective:To investigate the effect of psychological support during perithrombotic period on post-stroke depression (PSD) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS received intravenous thrombolysis in the Affiliated Lianyungang Hospital of Xuzhou Medical University from January 1, 2021 to July 31, 2021 were enrolled prospectively. The intervention group received one-to-one individual psychological support therapy in the perithrombolytic period on the basis of receiving standard intravenous thrombolytic therapy. At 30 d after onset, Hamilton Depression Scale was used to assess whether PSD occurred. Multivariate logistic regression analysis was used to evaluate the independent influencing factor of PSD. Results:A total of 126 patients with AIS were enrolled, and 86 of them were male (68.25%). Their age was 63.65±10.46 years; 65 were in the intervention group and 61 were in the control group. The incidence of PSD in the intervention group was significantly lower than that in the control group (20.00% vs. 36.07%; χ2=4.049, P=0.044). Multivariate logistic regression analysis showed that psychological intervention (odds ratio [ OR] 0.333, 95% confidence interval [ CI] 0.132-0.838; P=0.020] was an independent protective factor for PSD, while ischemic heart disease ( OR 4.510, 95% CI 1.181-17.217; P=0.028), alcohol consumption ( OR 3.421, 95% CI 1.317-8.888; P=0.012), anticoagulation therapy ( OR 3.145, 95% CI 1.155-8.567; P=0.025) and modified Rankin Scale score before thrombolysis ( OR 1.627, 95% CI 1.142-2.317; P=0.007) were the independent risk factors for PSD. Conclusion:Perithrombolytic psychological support may reduce the incidence of PSD.
