Objective To observe the serum levels of Gal-3,Hs-CRP,IL-6 and TNF-α,and discuss the correlation between those indicators and the severity of coronary lesion and major adverse cardiac events( MACE). Methods Serum levels of Gal-3,Hs-CRP,IL-6 and TNF-α were detected in 126 patients with coronary heart disease and 54 patients with non-coronary heart disease. To analyze the correlation between those indicators and the severity of cor-onary lesion and MACE. Results Serum levels of Gal-3 and inflammatory factors of in the coronary heart disease group were significantly increased compared with the control group(P<0. 01),and serum levels of Gal-3 and in-flammatory factors in the multi-vessel disease group and the severe coronary disease stenosis group higer than that of the double-vessel disease group,the single-vessel disease group and the mild coronary disease stenosis group ( P<0. 05). Serum levels of Gal-3,inflammatory factors and Gensini scores were positively correlated(P<0. 01). Ser-um levels of Gal-3 , inflammatory factors were significantly higher with MACE compared to without MACE ( P <0. 05). Conclusion The serum levels of Gal-3 and Hs-CRP,IL-6,TNF-α,Gensini scores in patients with coronary heart disease are positively correlated,serum Gal-3 has great potential to become effective clinical indicators,which could be used to preliminary predict the severity of coronary artery disease and evaluate the short-term prognosis of patients with coronary heart disease.

OBJECTIVE:To investigate the clinical efficacy of alprostadil combined with edaravone in the treatment of unsta-ble angina pectoris(UAP),and their effects on serum oxidative stress indexes,the levels of MMP-2 and MMP-9. METHODS:Be-sides conventional treatment,control group was treated with Alprostadil injection 2 ml added into 0.9% Sodium chloride injection (NS)100 ml,ivgtt,qd;while observation group was additionally treated with Edaravone injection 15 ml added into NS 100 ml, ivgtt,qd. Treatment courses of 2 groups lasted for 2 weeks. The frequency and duration of UAP attack,serum levels of MDA, SOD,TAC,MMP-2 and MMP-9 levels were observed 2 groups;the occurrence of ADR was also observed. RESULTS:There was no statistical significance in frequency of angina pectoris attack,duration,MDA,SOD,TAC,MMP-2 and MMP-9 between 2 groups before treatment (P>0.05). After treatment,the total effective rate of observation group (94.3%) was significantly higher than that of control group(81.4%). The frequency of angina pectoris attack and the level of MDA,were significantly reduced,and the duration of angina pectoris was significantly shortened SOD and TAC increased significantly;the change of observation group was more significant than that of control group with statistical significance(P<0.05). ADR was mild in 2 groups;there was no statisti-cal significance in the incidence of ADR(P>0.05). CONCLUSIONS:Alprostadil combined with edaravone is significantly effec-tive for UAP,reduces the frequency of angina,shortens the duration of angina pectoris,alleviates oxidative stress and reduces se-rum levels of MMP-2 and MMP-9 with good safety.

Objective To investigate the effects of subclinical hypothyroidism (SCH) on blood glucose and metabolic parameters in type 2 diabetes (T2DM) . Methods A total of 973 T2DM patients were recruited, and the clinical data, biochemical and thyroid function parameters were measured. One hundred and forty eight T2DM patients were diagnosed as SCH (SCH group) and 152 euthyroid patients were selected as control group (NSCH group) . Results (1) The prevalence of SCH in type 2 diabetes was 15.3% (148/973) . (2) Compared with the NSCH group, the prevalence of overweight/obesity was significantly higher in SCH group (54.1%vs 35.5%,<0.01) as well as hypertension (64.9%vs 52%, <0.05) . There was no significant difference in HbA1c control and prevalence of dyslipidemia and hyperuricemia between two groups. Conclusion SCH may have some adverse effects on blood pressure and BMI in T2DM.

Objective To study the levothyroxine doses and related factors in the treatment of pregnant women with subclinical hypothyroidism (SCH).Methods Fifty-six pregnant women with SCH (diagnosed before 12 weeks of gestation) were recruited and divided into 2 groups according to the baseline TSH levels,SCH group 1 (2.5 mIU/L ≤ TSH ≤ 5.0 mIU/L,n =24) and SCH group 2 (TSH＞5.0 mIU/L,n =32).Thyroid autoantibodies [thyroid peroxidase antibody(TPOAb) and thyroglobulin antibody(TGAb)] were detected.All the subjects were treated with levothyroxine and the doses were adjusted according to the TSH level.The therapeutic target was to keep the TSH levels under control,0.3 to 2.5 mIU/L for the first trimester and 0.3 to 3.0 mIU/L for the second and third trimesters.Results There was a positive correlation between the levothyroxine doses and baseline TSH levels (r =0.533,P＜0.01) in pregnant women with SCH.A significant difference in the levothyroxine doses between SCH group 1 and SCH group 2 was found [(0.583 ± 0.341) vs (0.961 ± 0.405) μg/kg,t =-3.695,P＜ 0.01].The levothyroxine doses in SCH group 2 were 64.84％ higher than those in group 1.There was a significant difference in the levothyroxine doses between thyroid autoantibody negative and positive subjects [(0.680 ± 0.370) vs (0.918 ±0.440) μg/kg,t =-2.197,P =0.032].The levothyroxine doses in thyroid autoantibody positive subjects were 35 ％ higher than those in the negative subjects.In addition,there was a significant difference in the levothyroxine doses between subjects with negative and positive thyroid autoantibody [(0.421 ± 0.192) vs (0.720 ± 0.385)μg/kg,t =-2.331,P =0.029] in SCH group 1.While in SCH group 2,the difference did not reach statistical significance.Conclusion The baseline TSH levels and status of thyroid autoantibodies may affect the levothyroxine dosage in pregnant women with SCH.

Subclinical hypothyroidism during pregnancy is associated with some adverse outcomes during maternal pregnancy.The present study investigated thyroid function parameters measured by electroehemiluminescence (ECL) immunoassays in subclinical hypothyroid women treated with levothyroxine (L-T4) during pregnancy.The results showed that in evaluating thyroid function with ECL immunoassays during replacement with L-T4,determination of serum TT4 appears to have a closer correlation with TSH and may better reflect the effìcacy of treatment.

Objective:To compare two flexible embryo catheters and determine whether clinical out-come differs in the in vitro fertilization-embryo transfer (IVF-ET)cycles.Methods:This prospective control study was conducted by one doctor between July 2012 and November 2013.In the study,2 064 patients undergoing fresh embryo transfer by using IVF-ET/intracytoplasmic sperm injection (ICSI)-ET in Reproductive Medical Center of Peking University Third Hospital were recruited.The subjects were di-vided into two groups.Cook Sydney IVF embryo transfer catheters (product model:K-JETS-7019-SIVF) were used for embryo transfer in group 1 (n =949),and FrydmanCCD catheters (product model:131230301)were used in group 2 (n =1 115).Pregnancy outcomes were compared between these two groups.Results:There was no significant difference in age,diagnosis for infertility and stimulation proto-col used between the two groups.In addition,there was no difference in the number of oocytes collected and in the number and score of embryos transferred.The significantly higher implantation rate,clinical pregnancy rate,and live birth rate (34.40% vs.26.92%,51.21% vs.41.52%,42.57% vs. 33.09%,P <0.05)were observed in group 1 compared with group 2.The abortion rate was not signifi-cantly different between the two groups (11.93% vs.15.98%,P >0.05).The proportion of difficult transfer was higher in group 1 than that in group 2 (5.27% vs.3.41%,P <0.05 ).There was no difference in the clinical pregnancy rate and live birth rate between the two difficult transfer cycles.Con-clusion:The type of embryo transfer catheter affects the clinical outcome in IVF.Good clinical outcome can be obtained by using Cook Sydney IVF catheter,which is worthy of clinical promotion.

Objective To compare the diagnostic efficiency between blastomere preimplantation genetic diagnosis (PGD) and polar body PGD for chromosomal translocation carriers. Methods Group A had 8 cycles using whole painting probes for the first polar body diagnosis, while group B had 29 cycles using two subtelomeric probes and one centromeric probe for the blastomere diagnosis. Results The fertilization rate of group A was significantly lower than group B [66. 1% (72/109) vs 85.2% (304/357) , P < 0.05]. There was no significant difference in the successful biopsy rate between two groups. However, group A had a significantly higher loss rate during fixation and higher no signal rate after fluorescence in situ hybridization [ FISH, 9. 6% (12/104) vs 1.6% (4/252), 11.2% (10/89) vs 3.0% (7/233) ]. Totally, the diagnostic efficiency in group A (72. 5% ,79/109 ) was significantly lower than that in group B( 89. 8%, 230/256, P < 0. 05 ). Although both the clinical pregnancy rate( 3/7 ) and implantation rate( 22. 2% ,4/18 ) of group A were higher, the differences were not statistically significant ( P > 0.05 ). Conclusion Both methods can be used efficiently in the PGD for chromosomal translocation carriers. Blastomere PGD has a higher diagnostic rate.

Objective:To introduce a novel ridge preservation technique with micro-titanium plate avoiding the use of bone grafting materials,and evaluate the potential horizontal bone preservation effect of this new technique,applied on single maxillary central incisors after tooth extraction for future implant restoration.Methods:Nine patients (six women and three men),mean age (26.0 ±5.7)years(from 1 8 to 34 years)referred to the Department of Oral Implantology,Peking University School and Hospital of Stomotology,were selected and diagnosed with unsalvageable single middle incisor with fine general con-ditions,no signs of acute local inflammation,no ongoing or previous periodontitis,healthy neighboring teeth and intact buccal bone walls.Tooth extraction,delayed implant placement and implant-supported single crown restoration were selected as treatment plan.The teeth were extracted atraumatically with lo-cal anesthesia,followed by a reflection of a minor flap to exposed 2-3 mm of the buccal bone plate.Af-ter that,a micro-titanium plate was trimmed and bended to fit the convexity of the labial bone and fixed by two mini pins with intent to support the labial soft tissue.The flap was then repositioned over the micro titanium plate and secured with two single sutures.No bone grafting materials or releasing incisions were needed.The sockets were left to heal without any intention of primary wound closure.Cone-beam compu-ted tomographic (CBCT)scans were obtained before and four months after tooth extraction.Horizontal ridge widths were measured with CBCT software,and the preservation effects were calculated and recor-ded by the percentage of horizontal ridge alteration.Results:The nine extraction sockets were healed un-eventfully.The average socket width before extraction was (7.51 ±0.48)mm (6.92-7.82 mm).The average alveolar ridge labial-palatal width at the control point of the edentulous area was (6.81 ±0.44) mm (6.04-7.38 mm)4 months after tooth extraction,the mean percentage of ridge width preserved was 90.87%±2.91%(87.28%-95.60%).Conclusion:This novel ridge preservation method by the usage of a micro-titanium plate did not interfere with the natural socket healing process,and at the same time,largely preserved the width of alveolar ridge without any bone grafting procedures.Long term results remain to be seen.

Objective To investigate the effect of rehabilitation on memory deficits after acquired brain injury, to compare different training models of memory rehabilitation and to analyze the possible factors affecting memory rehabilitation. Methods 144 patients with acquired brain injury following memory deficits were randomly assigned to computer-assisted training group, face-to-face training group and control group. Both training groups were given memory-based cognitive training program once a day which sustained 30 minutes for 6 or 12 weeks. The instantaneous memory, short-term memory and long-term memory were evaluated and compared before and after training. The effect of gender, age, education, course, site of injury and coma time on training efficacy were analyszed as well. Results 6 weeks and 12 weeks at training, both computer-assisted and face-to-face training groups showed a significant improvement in memory abilities when compared to controls (P<0.01), with the former making more progress (P<0.01). Negative correlation was found between age and memory performance. Conclusion Effectiveness of memory rehabilitation is proven. 12 weeks training can significantly improve memory. Cognitive training using professional equipment is significantly more effective than the face-to-face training and should be recommended.
