Objective To investigate the effect of interferon alfα-2b on the ultrastructure and Caspase-3 levels in villus in early pregnancy with bacterial vaginal disease (BV). Method Early pregnant women were divided into two groups. The treated group included 25 early pregnant women with BV who chose to have an early termination and were treated with rhINFα-2b. The controling group included 30 early pregnant women without any genital tract infectious diseases. The caspase-3 levels in trophocytes were detected by immunochemistry and the ultrastructural changes were observed in villus by transmission electron microscopy. Result (1)There was no apparent difference of ultrastructural changes between the two groups. (2)There was no statistical significance of the levels of caspase-3 between the two groups (P>0.05). Conclusion The excessive apoptosis do not occur in the trophocytes when treated with INFα-2b.

Genome-wide association study (GWAS) has been increasing rapidly worldwide in recent years, along with more attention to heredity and genetic polymorphism of diseases.The single nucleotide polymorphism (SNP) is the most common genetic variant in the human genome, which can influence gene expression, transcription, translation and modification, and has become one of the important causes of disease susceptibility.Not only is uric acid related SNP susceptible to hyperuricemia and gout, but also plays an important role in the circulation, respiration, and nervous system diseases.Therefore, the present paper reviews the relationship between uric acid related SNP and clinical diseases in order to bring a new perspective on prevention and treatment.

Objective To observe the changes of red blood cell distribution width, mean platelet volume and cardiac troponin I in patients with Acute Coronary Syndromes, and to evaluate the value for early diagnosis by using ROC curve. Methods 191 patients with ACS and 206 patients with the chest pain syndromes non-ACS were selected in this study. Electrocardiogram,blood routine,creatinine, LDL-C and cardiac troponin I were determined within six hours after hospitalized,meanwhile the feature of ROC curves was observed. Results There was no significant difference between ACS group and non-ACS group about red blood cell, hemoglobin, platelet,creatinine and LDL-C［(3.82±0.57)×1012/L,(101.3±3.3)g/L,195（98.6-334.8）×109/L,69（45-120）μmol/L,(2.95±0.85)mg/dl vs (3.89±0.50）×1012/L,(103.5±3.7)g/L,201（135.2-346.9）×109/L,71（49-100）μmol/L,(2.82±0.75)mg/dL］ (P＞ 0. 05). Red blood cell distribution width, mean platelet volume and the cardiac troponin I in ACS group［13.70(12.00-15.20)%,9.4（7.42-12.31）fL,(5.63±1.39)μg/L］ were significantly higher than that of non-ACS group［12.60（11.20-13.83）%,8.2（6.24-10.97）fL,(0.04.±0.01)μg/L］ (P＜0.01) .The area under ROC curves of red blood cell distribution width,mean platelet volume and cardiac troponin I were 73.5%, 78.8%, 98.1% respectively, while the best cut-off value was 13.15%, 12.45 fL, 0.06 μg/L respectively. Conclusions The combination using of red blood cell distribution width andmean platelet volume and cardiac troponin I and other conventional cardiac markers might be served as early diagnosis marker for the ACS patients admitted to emergency departments.

An LC-MS/MS method was developed to investigate the pharmacokinetic parameters in healthy Chi-nese volunteers following single and multiple oral administration of dimemorfan phosphate. In the Single-dose study,two-period and crossover study was conducted in 12 healthy volunteers,which were administered with single-dose of 10 mg or 40 mg of dimemorfan phosphate. And another 12 volunteers were administered with 20 mg. The values of AUC0-48 h,t1/2,and cmax were (11. 81 ±14. 46),(52. 60 ±96. 01 )and (34. 70 ±29. 59)ng. h/mL,(12. 11 ±2. 54),(12. 16 ±2. 01)and (12. 77 ±1. 27)h,and (0. 9653 ±0. 8178),(3. 150 ±3. 451)and (2. 167 ±1. 650)ng/mL for 10 mg,40 mg and 20 mg oral administration. The same 12 healthy volunteers as the group of single-dose of 20mg were participated in multiple-dose study,which were administered dimemorfan phos-phate 20 mg,three-time a day until the day-8,showed AUC0-48 h,t1/2,and cmax were (115. 9 ±135. 2)ng.h/mL, (11. 22 ±1. 61)h,and (7. 418 ±7. 010)ng/mL. The accumulation parameter Rcmax and RAUC was (3. 14 ±1. 34) and (3. 38 ±1. 22),respectively. Dose proportional of cmax and AUC was not concluded ranging from 10 mg to 40 mg after confidence interval criteria method. An accumulation was occurred after multiple -dose administra-tion with the consequence. And the results demonstrated significant individual difference.

Objective To study the diagnosis and treatment of hyperthyroidism companied with thyroid carcinoma . Methods The clinical data of 11 cases of hyperthyroidism with thyroid carcinoma were retrospectively analysed. Results 9 of 11 cases were diagnosed preoperatively,and comfirmed by frozen section intra-operatively and underwent suitable operation. In the other two cases the final diagnosis was made by pathological examination postoperatively, and re-operation was performed on 1 case . All the patients were followed up for 1～16 years and neither hyperthyroidism nor thyroid carcinoma recurred. Conclusion It is difficult to make diagnosis of hyperthyroidism with thyroid carcinoma preoperatively. B mode ultrasonography may find some nodes in enlarged thyroid; but fine needle aspisation biopsg(FNA) has high false negative diagnostic rate. Intra-operative frozen section examination is important in the diagnosis of hyperthyroidism with thyroid carcinoma .

Objective To observe the effect of long-term intensive glucose control therapy on diabetic retinopathy in outpatients with type 2 diabetes mellitus.Methods Forty-nine patients with type 2 diabetes mellitus were randomly assigned to participate in the trial from 2002 to 2007,receiving either intensive (24 cases) or standard glucose control (25 cases).The patients were examined by the same ophthalmologists to identify any new diabetic retinopathy (DR).After 5 years of intensive glucose control,all of the patients were asked to attend our clinic every 6 months,but no attempts were made to maintain their previously assigned therapies.Hemoglobin A1c (HbA1 c) was measured regularly.In November of 2009,a retinal examination was carried out by the same ophthalmologist who worked in the trial.The visual acuity,lens,vitreous body and fundus were examined after pupil dilation to identify diabetic retinopathy (DR).Fundus fluorescein angiography and retinal laser photocoagulation were carried out when necessary.Results In the second year after enrollment in the trail,the median HbA1c level of the intensive-therapy group was significantly lower than that of the standard-therapy group [(6.3 ± 0.6) ％ vs.(7.2 ± 1.2) ％,t =2.09,P ＜ 0.05],and was maintained in a controlled level throughout the following 4 years.During the post-trial monitoring,no new case of of macula edema or diabetic associated blindness occurred in either intensive or standard-therapy group,the whole occurrence of micro-aneurysms,fundus hemorrhage,as well as those who needed retinal laser photocoagnlation and lowering in visual acuity in intensive-therapy group was lower than that in the standard-therapy group (3 vs.14,1 vs.7,2 vs.4,3 vs.11,respectively ;9 vs.36,totally,x2 =4.719,P ＜ 0.05).During the first post-trial monitoring,there was no difference in median HbAlc level between intensive-therapy group and standard-therapy group [(7.2 ± 1.1) ％ vs.(7.3 ± 1.3) ％,t =0.25,P =0.806],which was sustained in the following years.In the trail,no new case of fundus hemorrhage or diabetic associated blindness occurred in intensive-therapy group during the five-year period of therapy.Number of new episodes of micro-aneurysm,macula edema were less in intensive-therapy group than that in standard-therapy group,number of new episodes of lowering in visual acuity,and those who needed retinal laser photocoagnlation,were significantly less in intensive-therapy group than that in standardtherapy group(15 vs.25,4 vs.23,Z =-4.459,P ＜ 0.05) during five-year follow-up.Conclusions The benefit of reduced incidence of diabetic retinopathy in intensive glucose can be maintained because of the legacy effect.

OBJECTIVETo analyze the relationship between symptoms and signs of temporomandibular disorders (TMD) and the patients' quality of life (QOL).

METHODSA total of 492 TMD patients were included in this study. The clinical examination results were recorded using Fricton index of temporomandibular joint function. "Visual analog scale (VAS) evaluation of QOL disturbance" was designed to quantitate patients' QOL, to evaluate the degree that the patients QOL was affected.

RESULTSChewing, daily life and emotion among all 8 items of QOL were frequently affected by TMD, and joint clicking had the least influence on QOL. Intermittent closed lock had more severe interference with QOL than joint clicking only. Severe and moderate pain or limited mouth opening affected the QOL more severely than mild pain or mild limited mouth opening. The simple linear relationship between Fricton index and patients' QOL was poor (r < 0.4).

CONCLUSIONSPain is the most frequently seen symptom in TMD. TMD could affect patients' QOL, including both physical and social-psychological functions. The results suggest that the patients' QOL as well as TMD symptoms and signs should be considered in the management of TMD.

Objective To investigate the situation and change of antifungal resistance in clinical Candida and other fungal iso- lates from 5 hospitals in diverse geographic region of China.Methods Antimicrobial susceptibility testing of 8 000 fungat iso- lates collected during 2001 and 2005 were carried out with 25?g fluconazole disk and 1?g voriconazole disk using disk diffusion method as recommend by CLSI/NCCLS M44-A.Disk test plates were automatically read and results were recoded with the BIOMIC Image Analysis System.The equivalent MICs were automatically calculated by the BIOMIC System software.Results The proportion of Candida atbicans and non-Candida albicans (e.g.Candida glabrata) in the total fungal isolates did not change significantly from 2001 to 2005.The susceptibility rate of C.albicans to fluconazole and vorieonazole were stable during 2001 and 2005.However, the resistance to fluconazole and voriconazole increased variably in C.glabrata and other non-Can- dida albicans fungal isolates during the same period.Conclusions The voriconazole demonstrated higher activity against all yeast species in comparison with fluconazole.The increasing resistance to fluconazole and voriconazole in non C.albicans fungal isolates including C.glabruta suggests the importance of surveillance of fungal resistance in Candida isolates.
