Objective To explore the efficacy and safety of terminating biochemical pregnancy (the stage in which intrauterine or ectopic pregnancy cannot be confirmed) with mifepristone and misoprostol. Methods Mifepristone (150 mg) combined with misoprostol (600 ?g) 3 days later were given to 500 biochemical pregnancies (G_1),500 early clinical pregnancies (G_2) and 500 clinical pregnancies (G_3) which were classified according to amenorrhea days,serum human chorionic gonadotropin-beta subunit (?- hCG) and vaginal B-ultrasonic examinations.All were observed for 6 hours after taking misoprostol and returned for assessment per week.Results Expulsion of conceptus was G_1 123 (24.6%,123/500),G_2 438 (87.6%,438/500) and G_3 467 (93.4%,467/500).Failure rate was G_1 6 (1.2%,6/500),G_2 24 (4.8%,24/500) and G_3 79 (15.8%,79/500) for ongoing pregnancies,hospitalizations for suspected ectopic pregnancies and surgical intervention for heavy or long-time bleeding.Bleeding cases during the administration of mifepristone were G_1 272 (54.4%,272/500),G_2 141 (28.2%,141/500) and G_3 87 (17.4%,87/500);the mean bleeding days were G_1 (5.8?1.5),G_2 (9.0?2.9) and G_3 (14.3?5.9) days.Other side effects including abdominal pain,nausea,vomiting and diarrhea were low and light in each group,increasing with advancing gestational age.Menses recovery was 486 (97.2%,486/500),452 (90.4%,452/500) and 433 (86.6%,433/500) for each group on scheduled time.Satisfaction was 499 (99.8%,499/500),485 (97.0%,485/500) and 369 (73.8%,369/500) respectively.Conclusion Mifepristone and misoprostol in combination is as safe,and effective for termination of biochemical pregnancies as ordinary medical abortion.It does not need to wait till ectopie pregnancy is excluded.

OBJECTIVETo evaluate the small fiber function in patients with type 2 diabetes mellitus of the early stage by measuring the sensory threshold with the quantitative temperature testing technology.

METHODSTwenty cases of patients with type 2 diabetes with no neurological deficit (DM group) and twenty age and sex-matched healthy controls underwent the detecting of cold sensory threshold (CST), warm sensory threshold (WST), cold pain threshold (CPT), heat pain threshold (HPT) in both inside of their hands.

RESULTSThere was no significant difference in CST, WST, CPT and HPT between left and right inside of hand of the same sample among all the testers. But the four kinds of threshold showed significant difference in the right inside of hand between patients and healthy people ( P < 0.05). In addition, the CST and WST differed significantly in the left inside of hand between the patients and healthy controls while the CPT and HPT showed no significant difference in the left inside of hand between them. Patients group and control group with CST and WST on the left side of the comparison difference was statistically significant (P < 0.05).

CONCLUSIONQuantitative analysis of temperature sense threshold can not only reflect increase of the pain threshold value, also can reflect its decrease, i. e. hyperalgesia, which may help to diagnose small fibrous peripheral neuropathy recognition, especially in early diabetic peripheral neuropathy.

BACKGROUND: Microglial cells are prominently involved in certain neurologic diseases such as Parkinson disease and Alzeheimer disease. In vitro primary culture is commonly used in studies on the functions of microglia.However, these classical culture methods have some defects including complex procedures and low out-put.OBJECTIVE: To establish a simplified high-output primary culture of microglia.DESIGN: An explorative experiment with microglial cells as the single sample.SETTING: Department of Neurology, Affiliated Union Hospital, Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The study was finished at the Central Laboratory of Union Hospital from April to October 2004. Microglial cells were obtained from 10 newborn(one day) male Kunming mice that were selected.METHODS: The author' s culture method was based on McCarthy method, we developed a new culture method and made some improvements,including the increased cell density for primary culture and nutritional deprivation. The microlglial cells were isolated with low-concentration trypsin-EDTA(ethylene diamine tetraacetic acid) digestion and immunochemically labeled with MAC-1 antibody, so as to measure the output and purity of microglia.MAIN OUTCOME MEASURES: ① Morphologic features of microglial cells, observed with inverted microscope; ② Purity and activity of microglia cultured with these two methods, were measured immunohistochemically.RESULTS: For microglia cultured with McCarthy method, the culture cycle was 20 days and the output was 2 × l05 cells per flask with a purity of 95% -97%. The new method shortened the culture cycle to 15 days and the output reached 1 × 106 cells per flask with a purity of 96-98%. Cell purity and activity had no significant difference between these two culture methods.CONCLUSION: The new method has a similar purity and activity with classical method; however, it may simplify procedures, shorten cycle, and increase output, and therefore can be a useful method for studies on microglia function and for nerve repair.
