OBJECTIVE:To investigate the characteristics and influential factors of adverse drug reactions(ADRs)of docetax-el in our hospital,and to provide suggestions for clinical rational drug use and individualized administration. METHODS:Medical records of patients receiving anti-tumor chemotherapy were extracted from hospital information system(HIS)of our hospital during Apr. 2014 and Oct. 2015,and Docetaxel related ADR reports were collected and comprehensively analyzed by retrospective classi-fied statistics. RESULTS:Among 417 cases,105 cases of docetaxel related ADR were reported. There were 69 patients aged 50-69 with highest ADR frequency. The ADR incidence of female patients was higher than that of male patients (29.29% vs. 19.66%). The incidence of docetaxel related ADR and arrest of bone marrow increased as the increase of drug dosage;the incidence of breast cancer ADR was the highest (46.03%),followed by lung cancer (37.25%) and gastric cancer (25.00%). The incidence of docetaxel+platinum chemotherapy plan ADR was the highest (35.10%). Main organs/system involved in ADR was hematological system (55.65%). CONCLUSIONS:The individual difference of docetaxal related ADR are great and affected by several factors. Individual physical condition of patients should be taken into consideration as early as possible,which can reduce the incidence of ADR and promote clinical rational drug use.

Objective: To analyze the electrocardiographic (ECG) characteristics in patients with primary hyperparathyroidism (PHPT) and meanwhile, to explore the relationship between ECG abnormality and serum calcium level in relevant patients. Methods: Our study included 2 groups: Observation group,n=84 PHPT patients treated in our hospital from 2010-01 to 2014-04 and Control group,n=80 normal subjects from regular physical examination at the same period. The ECG manifestation was compared between 2 groups. Meanwhile, according to tertile levels of serum calcium, PHPT patients were further divided into 3 subgroups:①Ca2+ level (2.0-2.8) mmol/L,②Ca2+ level (2.8-3.1) mmol/L,③Ca2+ level >3.1 mmol/L andn=28 in each subgroup. The ECG abnormalities were compared among 3 subgroups and the relationship between ECG changes and serum calcium levels were studied. Results: The ECG abnormality rates in Observation group and Control group were as 83.3% vs 18.8%, P<0.001. Compared with Control group, Observation group presented more frequent ST-T changes, QRS duration widening, high left ventricular pressure and QT interval shortening,P<0.001 orP<0.05. In observation group, with the rising of serum calcium, the incidences of ST-T changes and high left ventricular pressure were increased accordingly, the ST-T changes among 3 subgroups were significant,P<0.05; while with the rising of serum calcium, the QT interval was shortened and QRS duration was widened accordingly, the differences were obvious among 3 subgroups, allP<0.05.Conclusion: PHPT patients have the higher incidence with abnormal ECG, while ECG abnormality has beenrelated to serum calcium level in relevant patients.

BACKGROUND:The biomechanical properties of naturaly regenerated damaged articular cartilage that belongs to the fibrovascular tissue are far worse than those of the normal cartilage so that they cannot meet the requirements for joint function, leading to traumatic arthritis and loss of joint function.
OBJECTIVE:To evaluate the effects of matrix metaloproteinase-3 (MMP-3) inhibitor I with different concentrations on the early-stage repair of ful-thickness articular cartilage defects in the knee of rats.
METHODS: Twenty-four Sprague Dawley rats were randomized into control, defect (DEF), and defect combined with low-(D+L) and high-dose inhibitor (D+H) groups (n=6 for each group), respectively. Full-thickness articular cartilage defects followed by intraarticular injection of low- and high-dose MMP-3 inhibitor I for 4 weeks was administered in the later two groups. Serum MMP-3 was detected using ELISA method before and after experiment, respectively. Femoral trochleas were collected to observe characteristics of repaired tissue by gross appearance scoring and O’Driscoll histological scoring with Safranine O-Fast Green staining, and to measure type II colagen by immunohistochemistry after experiment.
RESULTS AND CONCLUSION:Rats in the D+H group had obvious repair similarly to hyaline articular cartilage, while creamy white cartilage tissue and fibrous tissue repair were observed in D+L group and in DEF group. D+H group obtained the best repair results according to gross appearance scoring and O’Driscol histological scoring and the highest content of type II colagen (P< 0.05). MMP-3 concentration and the difference value before and after experiment were gradualy decreased in DEF, D+L, D+H, and control groups in sequence(P< 0.05). These findings demonstrate that MMP-3 inhibitor I accelerates the early-stage repair of ful-thickness articular cartilage defects in the knee of rats.

Background and purpose:Smac/DIABLO was the only apoptosis-related protein that could inhibit IAPs directly and simultaneously.The four amino-residual AVPI(Ala-Val-Pro-lie)in its N-terminal was the very important domain that could stimulate apoptosis.This study investigated the effect of synthetic Smac peptide (SmacN7) on chemotherapy sensitivity of bladder cancer cells.Methods:SmacN7 penetratin peptide was synthesized and delivered into T24 cells.MTT assay was adopted to evaluate the viability of T24 cells induced by low-dosage of MMC. Flow cytometry was applied to analyze the proportion of apoptosis and Western blot was used to detect the expression of XIAP and caspase-3;The activity of caspase-3 was measured and the effect of SmacN7 combined with MMC on T24 cell lines was also determined.Results:SmacN7 penetratin peptide could successfully interact with endogenous XIAP and increase the proportions of apoptosis of T24 cell lines induced by low-dosage of MMC in a dose-and time- dependent manner.An obvious down-regulation of XIAP expression and up-regulation of caspase-3 was identified by Western blot.The activity of caspase-3 in experimental group was significantly increased as compared with that in the control group;Combining the treatment with SmacN7 penetratin peptide,the viability of T24 cells decreased to 55% and 72.7% in 24 hrs and 48 hrs respectively.Conclusion:SmacN7 penetratin peptide could act as a cell-permeable IAP inhibitor,inhibit the proliferation,induce apoptosis and enhance the chemo-sensitivity of bladder cancer cells to MMC. When combined with chemotherapy,it may be a very promising strategy for bladder cancer therapy.

Objective To discuss the significance of abnormal expression of Rb,p53 and PCNA in patients with bladder carcinoma and the correlation with the tumor grade,clinical stage and relapse.Meth- ods Immunohistochemical method was used to detect the Rb,p53 and PCNA gene expression in 60 cases with bladder carcinoma.Results The positive rates of p53,PCNA in 60 cases of bladder cancer is both 40.0 %.There were 27(45 %)cases lack of Rb expression.Multiple altered expression was found in 30 cases (50.0 %).The abnormal expression of Rb,p53 and PCNA was closely related to the tumor grade,clinical stage and relapse.Conclusion The detection of multiple gene is more valuable than that of single gene. Multiple altered expression of Rb,p53 and PCNA and their synergistic action might play an important role in the genesis and development of bladder cancer.

Emerging evidence has indicated that circular RNAs (circRNAs) play pivotal roles in the regulation of cellular processes and are found to be aberrantly expressed in a variety of tumors.However,the clinical role of circRNAs in bladder cancer (BC) and the molecular mechanisms have yet to be fully understood.In this study,the clinical specimens were obtained and the expression level of a circRNA BCRC4 was detected by real-time PCR in both BC tissues and cell line.The circular RNA over-expression plasmid was constructed and transfected into BC cells and related cell line.The cell cycles and apoptosis were observed using inverted microscope and flow cytometry.Western blotting was used to compare the relative protein expression of groups with different treatments.It was found that circRNA BCRC4 expression was lower in BC tissues than in adjacent normal tissues.Furthermore,consequences of fomed-expression of BCRC4 promoted apoptosis and inhibited viability of T24T and UMUC3 cells,and up-regulated BCRC4-inereased miR-101 level,which suppressed EZH2 expression in both RNA and protein levels.In addition,gambogic acid (GA) is a promising natural anticancer compound for BC therapy,and GA treatment increased the BCRC4 expression in T24T and UMUC3 cells in a dose-dependent manner.Altogether,our findings suggest that BCRC4 functions as a tumor suppressor in BC,and mediates anticancer function,at least in part,by up-regulating the expression of miR-101.Targeting this newly identified circRNA may help us develop a novel strategy for treating human BC.

Objective To explore the influence of thyroid dysfunction in the first half pregnancy (≤20 gestational weeks) on gestational diabetes. Methords By adopting the method of prospective intervention study, general data of pregnant-women in the care clinics of our hospital were collected. Thyroid function was detected and evaluated by ATA criteria. All cases were divided into two groups: normal thyroid function group and thyroid dysfunction group. The thyroid dysfunction group was intervened. 75 g OGTT were conducted in all cases in 24-28 gestational-weeks. GDM was diagnosed by IADPSG diagnostic criteria. GDM prevalence was compared between normal thyroid function group and abnormal thyroid function groups. Results 1 062 cases of pregnant women were collected. 857 cases of pregnant women were normal, while 14 cases were subclinical hyperthyroidism (1.32%), 164 cases were subclinical hypothyroidism (15.4%), 22 cases were hypothyroxinemia (2.07%). Compared with normal thyroid function, prevalence rate of GDM was the highest in hypothyroxinemia group (54.5% vs 27.8%). There was no significant difference between subclinical hypothyroidism group and normal thyroid function group. Conclusion Thyroid dysfunction in the first half pregnancy is associated with GDM , Screening and treatment of pregnant thyroid dysfunction should be attached.

Objective To study the compatibility of TCM prescriptions of TCM practitioners of all dynasties of Alzheimer disease (AD). Methods Amnesia, forgetting, dementia, and idiot were set as search words to retrieve relevant literature in Encyclopadia of Traditional Chinese Medicine. Prescription information was screened and standardized to build database. Frequency analysis and association rules were used to mine TCM prescriptions and compatibility rules. Results Totally 449 AD related prescriptions were selected, involving 682 Chinese medicinal herbs. The individual herb with the highest frequency was Ginseng Radix Rhizoma (192);the herbal pair with the highest frequency was Ginseng Radix Rhizoma-Polyhalae Radix (182);the herbal combination with 3 Chinese medicinal herbs with the highest frequency was Poria with Hostwood-Ginseng Radix Rhizoma-Polyhalae Radix (79);the herbal combination with 4 Chinese medicinal herbs with the highest frequency was Polyhalae Radix-Ginseng Radix Rhizoma-Poria with Hostwood-Glycyrrhizae Radix et Rhizoma (37). The results of association rules showed that Ginseng Radix Rhizoma-Polyhalae Radix, Ginseng Radix Rhizoma-Glycyrrhizae Radix et Rhizoma, and Ginseng Radix Rhizoma-Poria with Hostwood were commonly used compatibilities in AD related prescriptions. Conclusion Treatment of TCM practitioners in all dynasties for AD mainly chooses Chinese medicinal herbs with the efficacy of tonifying qi and soothing nerves. The compatibilities and combinations are reasonable and with certain representativeness.
