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.

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 investigate the drug susceptibility of clinical isolates in local region for using antibiotic reasonably. METHODS Totally 3 170 strains of clinical isolates were identified by API and Microscan and tested for drug resistance against antimicrobial agents by K-B method. WHONET5.4 was applied for analysis. RESULTS The commonly encountered bacteria were Pseudomonas aeruginosa (24.3%), Acinetobacter baumannii (10.9%), Klebsiella pneumoniae (10.4%), Escherichia coli (8.9%), and Staphylococcus aureus (SA,8.0%). In Gram-negative isolates, the resistance rate to meropenem was 19.7%, and to piperacillin-tazobactam was 26.5%. The incidences of E.coli and K. pneumoniae isolates producing extended spectrum beta-lactamases (ESBLs) were 49.1% and 33.5%, respectively. In Gram-positive isolates, the susceptibility rate to vancomycin and teicoplanin both was 100.0%. The oxacillin resistant rates of SA and coagulase negative Staphylococcus (CNS) were 54.2.0% and 82.3%. CONCLUSIONS The production ratio of ESBLs and oxacillin resistance of bacteria in local region are high. It is important to promote the rational use of antimicrobial agents and take effective contaminant methods to reduce resistant rates of bacteria and dissemination of multi-resistant bacteria.

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 .
