OBJECTIVE:To observe the efficacy and safety of mifepristone cycle therapy in the treatment of perimenopausal dysfunctional uterine bleeding. METHODS:Totally 116 patients with perimenopausal dysfunctional uterine bleeding were randomly divided into control group and observation group. Control group was given Mifepristone tablet 10 mg from 3 d after diagnostic cu-rettage on an empty stomach for continuous 90 d,once a day. Observation group was given Mifepristone tablet 10 mg from 3 d af-ter diagnostic curettage on an empty stomach,once a day,and it was stopped after continuous 5 d. Then it continued 5 d from the first day of menstruation,and lasted 3 menstrual cycles. The clinic data was observed,including clinical efficacy,estradiol(E2),fol-licle-stimulating hormone (FSH),luteinizing hormone (LH),progesterone (P),hemoglobin (Hb),endometrial thickness,men-strual conditions and recurrence in 2 groups before and after treatment were observed,and the incidence of adverse reactions were recorded. RESULTS:After treatment,E2,FSH,LH and P in 2 groups were significantly lower than before,and observation group was lower than control group,the differences were statistically significant(P<0.05). Hb in 2 groups was significantly higher than before,endometrial thickness was significantly lower than before,the differences were statistically significant(P<0.05);however, there was no significant difference between 2 groups(P>0.05). Total effective rate in observation group significantly higher than control group,normal proportion of menstruation were significantly better than control group,the differences were statistically sig-nificant(P<0.05). There was no significant difference in the incidence of a dverse reactions and dysfunctional uterine bleeding be-tween 2 groups(P>0.05).

BACKGROUND:The lumbar interspinous device, as a kind of non-fusion technology has been extensively applied in the clinic and exerts superiority in biomechanics compared with the traditional fusion technology. With the development of prosthesis design and impanation technology, it reveals a better application prospect. OBJECTIVE:To review the biomechanics and finite element analysis of lumbar interspinous devices. METHODS:The first author retrieved the databases of CNKI, WanFang, PubMed and SpringerLink using the keywords of“lumbar spine, interspinous devices, biomechanics, finite element analysis”in Chinese and English, respectively. Researches related to the biomechanics and finite element analysis of lumbar interspinous devices were included and repeated researches were excluded. A total of 44 literatures were enrol ed for review, including 8 Chinese and 36 English literatures. RESULTS AND CONCLUSION:(1) Biomechanical y, several interpinous devices, which are commonly used in the clinic, can increase the stability of the implanted segment in sagittal alignment by limiting the range of flexion-extension, with no significant change in lateral bending and axial rotation. (2) Few studies analyze the influence of the implant size and placement on the implanted segment and on the adjacent segments. (3) Through the stress nephogram, three-dimension finite element analysis can intuitively analyze the changes of the stress distribution in the intervertebral disc, isthmus and facet joints before and after implantation. Both biomechanical studies and finite element analysis indicate that interspinous devices can share the load of the disc and facet joints, and at the same time, make no effect on the range of motion and stress of the adjacent segment. (4) In conclusion, the short-term biomechanical advantage of the interspinous devices is obvious, but further studies are needed. The finite element analysis can simulate different body physical environment, and can analyze mechanical distribution changes after implantation, which is an effective way to evaluate the mechanical mechanism of the interspinous devices.

OBJECTIVE:To discuss the effect of Ethinylestradiol and cyproterone acetate tablet combined with metformin on ovulation induction of patients with polycystic ovarian syndrome(PCOS). METHODS:184 PCOS patients were randomly divided into control group(92 cases)and observation group(92 cases). Control group orally received 1 Ethinylestradiol and cyproterone ac-etate tablet in 5 d of menstruation,once a day,it stopped after 21 d,the next cycle of treatment was started on the 5th of with-drawal bleeding. Observation group additionally received 3 Metformin tablet,once a day,without drug withdrawal during menstrua-tion,and lasted for 3 menstrual cycles. After 3 menstrual cycles,all patients received ovulation induction treatment [(50-100 mg clomiphene was orally given from the 5th day of the 4th menstrual cycle,for 5 days,or 75-150 U postmenopausal gonadotropin by intramuscular injection,when the dominant follicle diameter was(19.0±2.0)mm,10 000 U human chorionic gonadotropin(HCG) was intramuscularly injected,the ovulation was continuously monitored and whether there was ovarian hyperstimulation syndrome (OHSS)was observed]. Body mass index(BMI),follicle estrogen(FSH),luteinizing hormone(LH),prolactin(PRL),estradiol (E2)and testosterone(T)before and after treatment,fasting plasma glucose(FPG),fasting insulin(FINS),insulin resistance in-dex(HOMA-IR),pregnancy rate,ovulation rate and the incidences of OHSS and adverse reactions in 2 groups were observed.RE-SULTS:Before treatment,there were no significant differences in the BMI,FSH,LH,PRL,E2,T,FPG,FINS and HOMA-IR between 2 groups(P>0.05). After treatment,BMI,LH,PRL,E2,T,FPG,FINS and HOMA-IR in observation group and LH, E2 and FINS in control group were significantly lower than before,and BMI,PRL,E2,T,FPG,FINS and HOMA-IR in observa-tion group were lower than control group,the differences were statistically significant(P<0.05). The pregnancy rate and ovulation rate in observation group was significantly higher than control group,the incidence of adverse reactions was significantly lower than control group,the differences were statistically significant (P<0.05). And there was no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Ethinylestradiol and cyproterone acetate combined with metfor-min can effectively improve insulin resistance of POCS patients,recovery sex hormone secretion,promote ovulation and improve pregnancy rate,with good safety.

BACKGROUND: The parameters of blood platelet(B-PLT) can reflect its thrombo-function, but the variation of blood-platelet parameters in patients with thrombotic disease is controversial and not unanimous.OBJECTIVE: To observe the changing rule of the B-PLT parameters in patients with cerebral infarction(CI), and investigate whether blood cell counter can be used in the evaluation of the variation of B-PLT parameters in CI patients.DESIGN: A case-control and experimental study based on patients and healthy people.SETTING: Department of laboratory and internal medicine in a university.PARTICIPANTS: During the January and March 2002, 37 CI patients including 28 males and 9 females aged 45 - 87 years were selected from Department of Neurology, Union Hospital Affiliated to Tongji Medical College,Huazhong University of Science and Technology. Among 37 healthy people,20 males and 17 females aged 40 - 60 years were selected as control group.METHODS: Platelet distribution width (PDW), mean platelet volume (MPV), platelet-large cell ratio(P-LCR) and the changing quantity of B-PLT of 37 CI patients were analyzed with blood cell counter, meanwhile,the healthy people were analyzed as control subjects.MAIN OUTCOME MEASURES: Changes of B-PLT parameters in two groups respectively.RESULTS: A positive relation between PDW and P-LCR was observed and between P-LCR and MPV as well( r = 0. 99, 0.92, P ＜ 0. 001 ). A negative correlation between B-PLT quantity and MPV was observed and also between B-PLTquantity and P-LCR(r= -0.58, -0.59, P ＜0.05) .In CI patients, PDW, MPV and P-LCR were(14.51 ± 2. 88)%, (10.95 ± 1.48) fl and(34.24 ± 11.23)% respectively, which were higher than those of healthy people [ (12. 86 ± 2.02)%, (10. 19 ± 1.29) fl, (28.47 ± 9.41 )% ]respectively, and the difference was significant( P =0. 019 31, 0. 021 77 and 0.026 35), but there was no significant difference between the two groups in B-PLT quantity.CONCLUSION: The blood platelets' parameters in CI patients, which reflect the function of the B-PLT, are significantly higher than those in healthy people. It shows that the enhanced function of platelet is a risk factor of cerebral infarction, the use of blood cell counter in analysis can observe the variation of the platelets' function rapidly and accurately. It can be a useful method of the therapy and prevention in CI patients.

The expression of CD44v6 in 105 cases of advanced cervical cancer was detected by using im munohistoehemical method and the relation between adhesion molecule CD44v6 and prognosis in advanced cervical cancer was investigated. The experimental results showed that the lymphocytic infiltration and peritumor reaction of fibrin in the stroma were milder in the patients with CD44v6 positive than those with CD44v6 negative. There were significant reductions in overall and free relapse survival in the patients with CD44v6 positive as compared with those with CD44v6 negative. It was suggested that the expression of CD44v6 might serve as a new indicator for predicting the prognosis of advanced cervical cancer. Tumor cells might interfere with the recognition of the peritumor lymphocyte and reduce the peritumor reaction of fibrin in the stroma through the expression of CD44v6.
