BACKGROUND:Resin infiltration is a novel approach in treating non-cavitated caries lesions on smooth surfaces, and the effectiveness comparison between resin infiltration and remineralizing therapy is required.
OBJECTIVE:To compare the effects of resin infiltration and remineralizing therapy on inhibition of non-cavitated lesions in vitro.
METHODS:Three subsurface lesions were created on 35 bovine labial specimens. One of the lesions was permeated with Icon? infiltrant, one was applied by 0.1%NaF solution daily for 7 consecutive days, whereas one lesion remained as the untreated control. Subsequently, half of each specimen was covered with nail varnish
(baseline) and the other half was re-exposed to a demineralizing solution for 5 days (experimental). The specimens were cut perpendicularly to the surface, stained with Rhodamine B and observed with fluorescence microscope.
RESULTS AND CONCLUSION:For lesions permeated with Icon? infiltrant and applied by 0.1%NaF solution, the progression of lesion depth was significantly decreased (P<0.05) compared with the untreated control. Lesions permeated with Icon? infiltrant got more significantly reduced lesion progression (P<0.05) compared with the ones applied by 0.1%NaF solution. It can be concluded that both resin infiltration and remineralizing therapy have active effects on inhibition of non-cavitated lesions, and fil ing the pores with Icon? infiltrant can inhibit further demineralization even better.

Objective:To analyze the operation technique and the methods to avoid early complications on the learning curve for bilateral direct anterior approach (DAA) total hip arthroplasty (THA).Methods: We retrospectively studied a series of continued cases with bilateral avascular necrosis of the femoral head (AVN) or degenerative dysplastic hip and rheumatoid arthritis that were treated by DAA THA in Beijing Jishuitan Hospital.A total of 22 patients with 44 hips were analyzed from June 2014 to August 2016 in this study.There were 17 males and 5 females,and the median age was 48 years(range: 34-67 years).All the surgery was done by DAA method by two senior surgeons.The clinic characters,early surgery treatment results and complications were analyzed.Results: We used the cementless stems in all the cases.The average operating time was (167±23) min;the average blood loss was (775±300) mL;the blood transfusion was in average (327±341) mL;the wound drainage in average was (111±73) mL Most of the patients could move out of the bed by themselves on the first day after operation,5 patients could walk without crutches on the first operating day,and 13 patients could squat on the third days after operation.The patients were discharged averagely 4 days after operation.We followed up all the patients for averagely 16 months (range: 8-24 months).There was no loosening or failure case in the latest follow up.In the study,2 patients had great trochanter fracture,2 patients had thigh pain,4 patients had lateral femoral cutaneous nerve palsy,and 3 patients had muscle damage.The Harris scores were improved from 29±8 preoperatively to 90±3 postoperatively (P<0.01).Conclusion: The DAA THA can achieve faster recovery and flexible hip joint after operation.However it is a kind of surgery with high technique demanding.Carefully selected patients,and skilled technique,can help the surgeon avoid the early complications.It is associated with high complication rate in the learning curve for bilateral DAA THA.

Objective To investigate the diagnostic values of human epididymis (HE4)in lung cancer.Methods 80 patients with lung cancer were the experimental group,30 patients with benign pulmonary disease were the benign control group,and 30 healthy people were healthy control group.The levels of carcinoma embryonic antigen (CEA),cytokeratin protein fragment 21-1 (CYFRA21-1),neuron specific enolase (NSE) and HE4 in serum were detected.Results The levels of CEA,NSE,CYFRA21-1 and HE4 in lung cancer patients were higher than those in both the benign control group and the healthy control group (P＜0.05).The areas (AUC) under the receiver operating characteristic (ROC curve) were 0.870,0.818,0.746 and 0.897 for serum CEA,NSE,CYFRA21-1 and HE4 levels in diagnosis of lung cancer.The levels of CEA and HE4 were higher in patients with adenocarcinoma,the level of CYFRA21-1 was higher in patients with squamous cell carcinoma,the level of NSE was higher in patients with small cell lung cancer (SCLC) (P＜0.05).The detections of CYFRA21-1 (AUC=1.000),CEA (AUC=0.727) and HE4 (AUC=0.622) in serum are favorable for the diagnosis of squamous cell carcinoma,The detections of serum CEA (AUC=0.954) and HE4 (AUC=0.944) levels are favorable for the diagnosis of adenocarcinoma,and the detections of NSE (AUC=0.876) was favorable for the diagnosis of SCLC (P＜0.05).Conclusion The levels of CEA,NSE,CYFRA21-1 and HE4 in serum were abnormal in patients with lung cancer.The HE4 level in the patients was correlated with the pathological types and the metastasis of lung cancer.The detection of serum HE4 could be used in the diagnosis and evaluation of lung cancer.

Objective To observe the expression of heparanase(HPA)in kidney of diabetic nephropathy(DN)rats and to investigate the role of HPA in the pathogenesis of proteinuria in DN rals. Methods DM rat models induced by intraperitoneal injection with streptozotocin were constnmted.Twenty-six rats were randomly divided into heahhy control group(n=6),DM6-week group(n=10)and DM 12-week group(n=10).Relative kidney weight(RKW),blood glucose,BUN,Scr,24-hour urine volume and(t 24-hour proteinuria quantilation were measured,and renal morphology was observed after 6 and 12 weeks.The expression of HPA was examined by immunohistochemistry and reverse transcription PCR. Results (1)Conq)ared with the control group,RKW,blood glucose,BUN,24-hour urine volume and 24-hour proteinuria quantitation of DM groups increased markedly(P＜0.05 orP＜0.01).(2)Compared to the control group,the expression of HPA mRNA and protein in DM groups increused significantly(P＜0.01).(3)HPA protein and mRNA were positively correlated with the quantification of urinary prolein (r=0.783,P＜0.01;r=0.793,P＜0.01). Conclusion The increased expression of HPA maybe parlicipate in the pathogenesis of proteinuria in DN.

Objective To compare the effectiveness of medicated γintrauterine device (IUD) and medicated genefix IUD inserted immediately after abortion. Methods A multicenter clinical trail was performed for the study from Mar. 2012 to Jan. 2013. Totally 840 women who volunteered to participate were randomly allocated to γ-group (medicated γ IUD) or genefix-group (medicated genefix IUD) immediately after abortion. While 464 abortion women who had not used IUD or steroids contraceptive methods were chosen as control group. The effectiveness of the IUD were followed up for 1 year. All women were required to record the number of vaginal bleeding days and blood volume of vaginal bleeding within 3 months after abortion. Results At the 12th month, the expulsion was the most common reason for termination. The expulsion rates of genefix-group and γ-group were 2.48/100 women years and 3.12/100 women years, respectively (P>0.05). For the expulsion reasons, IUD moving down could account for more than seventy percent. The removal rate for IUD usage of two IUD groups were almost equal (3.91/100 women years verus 4.35/100 women years), the differences were not statistically significant (P>0.05). At the 90th day after abortion, comparing with control group, the bleeding and (or) spotting days of genefix-group and γ-group extended by 3.9 and 2.6 days respectively, the differences had statistical significance between the three groups (P<0.05). Among the bleeding and (or) spotting days, spotting days prolonged significantly. At the 12th month, spotting days of genefix-group andγ-group were (9.2±5.9) days and (8.5±4.6) days respectively, more than (5.2 ± 4.0) days of control group. The differences had statistical significance between IUD with control group (P<0.05), and had not between the two kinds of IUD (P>0.05). Conclusion The insertion of medicated genefix IUD and medicated γ IUD immediately after abortion is safe, feasible, has slight side effects and could be effective contraception.
