Human epidermal growth factor receptor 2 (HER-2/neu) is an important prognostic predictor and the key predictor of anti-HER-2 therapy of breast cancer. Accurate testing of HER-2 status for breast cancer patients is important in clinical practice. As of this writing, the American Society of Clinical Oncology and the College of American Pathologists recommend three methods for HER-2 detection, namely, immunohistochemistry, fluorescence in situ hybridization, and bright-field in situ hybridization. The abovementioned methods have their own advantages and disadvantages. New methods, such as multiplex ligation-dependent probe amplification, quantitative reverse transcription polymerase chain reaction, and RNA in situ hybridization, are currently applied to detect HER-2 status. New technologies not only make up for the shortcomings of routine methods but also have unique benefits that can meet the demands for HER-2 testing of some breast cancer patients. Thus, these methods are promising for clinical applications and can improve clinical diagnosis and treatment. The characteristics, advantages, and drawbacks of these technologies are introduced and reviewed in this paper.

Objective:To check RNA binding protein QKI-5's expression level in breast cancer cells and inhibiting effect on cancer cell proliferation.Methods:QKI-5's expression level was checked in different breast cancer cells by Western blotting,cancer cells of overexpressed QKI-5 gene could be stabilized by slow virus infection construction,MTT and FCM were used to check cell period to express QKI-5's influence on cell proliferation and period.Results:MCF-7 cells have relatively low QKI-5 expression level in three breast cancer cells,MTT experiment result has obvious reduced influence on QKI-5's expression of MCF-7 cell proliferation P＜0.05,mean-while,cell period inspection shows that overexpressed QKI-5's MCF-7 cells have obvious G1 retardant,cells in S and G2/M periods are reduced.Conclusion:High expression of QKI-5'in breast cancer could cause slow cell proliferation by inhibiting cancer cell period,hence causing limited tumor growth.

Objective:To explore the curative effect and safety of febuxosta for the patients with primary gout complicated with mild to moderate renal insufficiency.Methods:60 male patients with primary gout complicated with mild to moderate renal insufficiency were enrolled in the affiliated Hospital of integrated traditional Chinese and Westem Medicine,Nanjing University of Chinese Medicine from January 2015 to August 2016 and randomly divided into two groups,the control group (n=30) was treated by allopurinol,and the study group (n=30) was treated by febuxosta treatment.The blood uric acid (BUA) and hepatorenal function were compared in the treatment period,and the incidence of adverse reactions and the recurrence of gout in post-treatment were compared.Results:At 1,2 and 3 month after treatment,the serum level of BUN in the study group was significantly lower than that of the control group (P＜0.05).The renal function of all patients were significantly improved compared with pre-treatment (P＜0.05),but the no significant difference was found between two groups at the same time(P＞0.05).The control group showed the adverse reactions with limb discomfort,drowsiness,nausea,abdominal distension,diarrhea and itch of skin,and the study group showed limb discomfort,drowsiness and abdominal distension,and one patients presenting allergic skin rash and discontinuation of allopurinol.The total incidence of adverse reactions in the study group was significantly lower than that of the control group (P＜0.05).Conclusions:Febuxosta could effectively and safely decrease the blood uric acid levels and improve the renal function of patients with primary gout complicated with mild to moderate renal insufficiency.

BACKGROUND: The number of roots and morphology of the root canal system of permanent mandibular first molars vary greatly among different populations; therefore, it is important to be familiar with the variations in the root and root canal for the location and negotiation of the canals. OBJECTIVE: To investigate the variations in the roots and root canal of permanent mandibular first molars in the Han population of southwest Shandong Province by cone-beam CT. METHODS: 656 patients undegoing cone-beam CT examination at the Department of Stomatology, Affiliated Hospital of Jining Medical University, from September 2012 to October 2015 were recruited, and all patients had healthy, well-developed, and untreated bilateral permanent mandibular first molars with normal appearance. Subsequently, the three-dimensional reconstruction based on cone-beam CT data was performed using Planmeca Romexis software to observe the variations in the root and root canal system of permanent mandibular first molars in the Han population of southwest Shandong Province. RESULTS AND CONCLUSION: Among 1312 permanent mandibular first molars, the incidence of permanent mandibular first molars with three roots was 70.66% (927/1312); the majority of root canal variations involved two roots and three root canals, accounting for 48.09% (631/1312). The incidence of distal root was 35.37% (232/656), the incidence of distal root was 29.34% (385/1312) in total teeth, and the incidence of distal root bilaterally was 68.95% (153/232). There was a significantly increased incidence of distal root on the right side than on the left side (P < 0.05), and the incidence in the male was significantly higher than that in the female (P < 0.05). These results suggest that most of Han populations in southwest Shandong Province have permanent mandibular first molars with two roots, and the root canal variations mainly involve two roots and three root canals, with the high incidence of distal root. Moreover, cone-beam CT is available for detecting the variation in roots and root canal system, which can provide references for root canal treatment.

Objective To assess the safety and effect of intraoperative cell salvage (ICS) during cesarean section.Methods This was a case-control study in which 60 gravidas who received ICS (ICS group) and 60 gravidas who received allogenic transfusion (control group) during caesarean section in Obstetrics and Gynecology Hospital of Fudan University during January 2014 to December 2016 were enrolled.Subjects in the two groups were matched in age,gestational age,gestational complications (placenta increta,placenta previa,scarred uterine,leiomyomas and anemia) and hemorrhagic volume during cesarean section.Several indicators including complications of transfusion,postoperative recovery,expense of transfusion,as well as the complete blood count and body temperature before and after operation were compared between the two groups.T,rank-sum or Chi-square test was used for statistical analysis.Results (1) No significant difference in age,gestational age,twin gestation,complications,preoperative body temperature,or the volume of hemorrhage or transfusion was observed between the two groups (all P＞0.05).(2) The autotransfusion volume was 385 (161-583) ml in the ICS group.Fifteen cases (20.0％) in the ICS group also received additional transfusions of leukocyte-reduced red blood cell (RBC) suspension,fresh frozen plasma and cryoprecipitate and two cases (3.3％) received additional transfusions of leukocyte reduced RBC suspension and fresh frozen plasma.The two groups showed no significant difference in the cost of transfusion or per-capita transfusion volume of fresh frozen plasma or cryoprecipitate.However,the transfusion volume of leukocyte-reduced RBC suspension was lower in the ICS group as compared with that in the control group [M(P25-P75),1.9 (1.5-4.5) vs 4.1 (2.8-6.2) U,Z=-2.800,P=0.005].(3) There was no significant difference in complete blood count or coagulation function between the two groups before the operation.White blood cell (WBC) counts in the two groups were elevated following operation.Postoperative WBC count in the control group was higher than that in the ICS group,while the levels of RBC and hemoglobin were lower than those in the ICS group following operation (all P＜0.05).(4) No amniotic fluid embolism was reported in the two groups.Only one case of rash was reported in the ICS group,which was fewer than the transfusion reactions occurred in the control group [1.7％ (1/60) vs 13.3％ (8/60),x2=5.886,P=0.016].(5) The two groups showed no significant difference in preoperative temperature,the highest temperature within three days after operation or incision healing.Compared with the patients in the control group,those in the ICS group had shorter hospital stay [(4.7± 1.1) vs (6.3 ±1.8) d,t=3.341,P＜0.05].Conclusion ICS is a safe and effective measure for gravidas at higher risk of hemorrhage during cesarean section.
