ObjectiveTo discuss the clinical value of serum CA125 and endometrial antibody (EMAb) for the diagnosis of endometriosis.Methods216 patients were determined by the presences of CA125 and EMAb before operation.ResultsAll cases were diagnosed by pathology after operation. CA125 positive rate in the endometriosis group was 58.3% and that in the control group was 12.5%. The difference between two groups was significant (P<0.01).EMAb positive rate in the endometriosis group was 31.3% and that in the control group was 14.3%. The difference between two groups was also significant (P<0.01). When determining CA125 alone to diagnose endometriosis, the sensitivity rate was 58.3% and specificity rate was 87.5%. If determining EMAb alone to diagnose endometriosis, the sensitivity rate was 31.3% and specificity rate was 85.7%. When one of them was used as diagnostic criterion, the sensitivity and specificity were 64.6% and 73.2% respectively. If combining use of both CA125 and EMAb as diagnostic criterion, the sensitivity and specificity were 25.0% and 100% respectively.Conclusions The determination of serum CA125 or EMAb levels is helpful for the qualitative diagnosis of endometriosis, especially using them combined, the diagnostic accuracy may be enhanced.

OBJECTIVETo investigate whether the cardioprotective effect of hemin against ischemia/reperfusion (I/R) injury is through the inhibition of calpain activity, and to explore its underlying mechanism.

METHODSSixty-four SD rats were randomly divided into eight groups (n = 8): sham, I/R, MDL+ I/R, MDL, hemin + I/R, hemin, and ZnPP + hemin+ I/R, ZnPP. Iangendorff isolated rat heart perfusion model was used. The rat hearts were suffered from 40 min of ischemia followed by 30 min of reperfusion. After that, left ventricular developed pressure (LVDP) was recorded. Infarct size and release of lactate dehydrogenase (LDH) were measured. Calpain, heme oxygenase (HO), and caspase 3 activities were evaluated. Expression of calpastatin protein was detected by Western blot.

RESULTS(1) After suffered from ischemia/reperfusion, the calpain activity and caspase 3 activity increased. MDL28170, an inhibitor of calpain, prevented ischemia/reperfusion induced increases in LDH and infarct size, improved the LVDP recovery. (2) Compared with ischema/reperfusion rat hearts, pretreatment of hemin enhanced the HO-1 activity, decreased the calpain and caspase 3 activities, declined LDH release and infarct size, and improved LVDP recovery. (3) Ischemia/reperfusion reduced the expression of calpastatin protein in rat hearts, which was inhibited by hemin pretreatment. And HO-1 inhibitor could abolish the cardioprotection of hemin.

CONCLUSIONCardioprotective effect of hemin against ischemia/reperfusion injury is through the inhibition of calpain activity, the mechanism might be involved in the increase in calpastatin protein expression.

Objective To make students at different levels not only learn theoretical knowledge of acupuncture-moxibustion manipulation skills but also achieve full operating training, strengthen the combination of theory and practice and improve the teaching quality of clinical disciplines by applyingmultimedia-subject participationteaching method to acupuncture-moxibustion manipulation techniques in the experimental teaching of acupuncture and moxibustion. Method The students were randomized, according to grade, into experiment (n=114) and control (n=115) groups. The teaching content was the same in the two groups. The experiment group received multimedia-subject participationteaching method. After the multimedia teaching, the students did an independent demonstration and made a self-evaluation, the teachers made a comment and the students did independent practice again in groups. The control group received conventional theory teaching and did practice under demonstration in the experimental lesson. The examination and questionnaire were used as assessment indicators to evaluate the effect ofmultimedia-subject participationteaching method applied to acupuncture-moxibustion technique teaching. Result Statistical analysis was made using the SPSS11.5 statistical software package. The independent samples t-test is used for a between-groups comparison. The statistical result showed that satisfaction was 100%in the experiment group and 75.7%in the control group;there was a statistically significant difference between the two groups (P<0.05). Conclusion Multimedia-subject participationteaching method is an innovation in acupuncture-moxibustion technique teaching and helps the students to better master acupuncture-moxibustion manipulation skills. Mastery of theoretical knowledge before real practice is the key to proficient manipulation. The combination of the two in classroom teaching yields twice the result with half the effort. Carrying out multimedia-subject participation teaching method will help to further deepen the teaching reform and to improve the level and quality of“Acupuncture and Moxibustion”teaching.
