Introduction to the influence of fixed in advance of NAP dyeing / 国际检验医学杂志

Objective To explore the influence of fixed in advance on the positive rate and integral of neutrophilic alkaline phosphatase (NAP) dyeing.Methods Totally 182 cases of fresh venous blood from inpatients in the top three hospital department of hematology were randomly selected and anticoagulated in the EDTA-K2 vacuum tube.Three blood smears from which were prepared as follows:the first blood smear(Named A) NAP dyeing completed within an hour;the second one (Named B) were fixed in advanceand NAP dyeing after one day;the third one (Named C) didn′t do any processing and NAP dyeing after one day.At the same time,the blood samples were taken from the fresh blood,and the blood smears were prepared and stained with NAP in an hour.NAP dyeing were performed by NAP dyeing for the blood smears,and 100 neutral rods,nucleus granulocyte were observed under microscope in the oil mirror vision,the test results record by positive rate and integral.Results No significant difference of NAP positive rate and integral was found in EDTA-K2 anticoagulation venous blood smear A when compared with fresh peripheral blood(P>0.05).The NAP positive rate and integral of EDTA-K2 anticoagulation venous blood smear B was slightly lower than that from fresh peripheral blood,but no significant difference was found(P>0.05).However,the NAP positive rate and integral in EDTA-K2 anticoagulant venous blood smear C has a significant difference from fresh peripheral blood(P<0.05).Conclusion The NAP dyeing results of EDTA-K2 anticoagulation venous blood smear fixed and placed one days are still reliable,while the NAP dyeing results was significantly reduced in the unfixed EDTA-K2 anticoagulation venous blood smear placed after one day.

Analysis of hyperthyroid heart disease by treatment with iodine-131 radioisotopes / 中国基层医药

Objective To analyze the effect of iodine-131I in the treatment of patients with hyperthyroid heart disease(HHD).Methods The clinical materials and therapeutic effect by 131 I were reviewed in 100 patients with HDD.Results The heal rate of hyperthyroidism and HHD were 82.3％,86.5％ in treatment group,and were higher than that of the control group (69.0％ and 76.2％ ) ( x2 =3.80,3.83,P ＜ 0.05 ) ; HHD with atrial fibrillation was 65.0％,average cardioversion after 131I treatment was 74.4％ after the treatment by 131I;The LVEDD、LVESD、LVEDV and HR after 131 I treatment were lower compared with before treatment ( all P ＜ 0.05 ),SV and EF were increased ( all P ＜ 0.01 ).Conclusion 131I treatment in patients with HHD,can significantly improve the efficacy of a heart disease

Transfer of ERR for radiation-related leukemia from Japanese population to Chinese population / 中华放射医学与防护杂志

Objective To establish a transfer model for excess relative risk (ERR) for radiation-related leukemia from Japanese population to Chinese population.Methods Combined ERR of several subtypes of leukemia published in 1994, with the corresponding leukemia baseline incidence rates obtained from Cancer Incidence in Five Continents Vol.Ⅸ (CI5-Ⅸ) for Japanese population and Chinese population, a weighted risk transfer model was employed between an additive model and a multiplicative model, to execute ERR transfer.Results A range of weighing factors was proposed for risk transfer models:weighing factor was 0.4 for male and 0.3 for female, acute lymphoblastic leukemia, acute myeloid leukemia and chronic myeloid leukemia.The uncertainty for ERR transfer was characterized by lognormal distribution.Conclusions Based on the difference of baseline incidence rate for subtypes of leukemia between Japanese population and Chinese population, the transfer model and these weighing factors discussed in the present study could be applicable to transfer ERR for radiation-related leukemia from Japanese population to Chinese population.

Treatment of 92 Cases of Adenomyosis in Perimenopausal Period with Levonorgestrel-releasing Intrauterine Device / 实用妇产科杂志

Objective:To investigate the clinical effects of levonorgestrel-releasing intrauterine device(LNG-IUD) in the treatment of adenomyosis in perimenopausal period. Methods: A total of 92 patients with adenomyosis in perim enopausal period were treated with LNG-IUD and followed up at the 3rd,6th, 12th,24th month. Change of menses, uterine volume,visual analogue scale (VAS) of dysmenorrhea,the serum CA_(125) level and degree of satisfaction with the treatment were observed. Results:The dysmenorrhea was alleviated along with the follow-up time in all of the pa tients after insertion of the LNG-IUD ( P<0.05). The menstrual volume, uterine volume and serum CA_(125) level were decreased significantly(P<0.05) .Conclusions:LNG-IUD is a safe, effective and simple treatment of adenomyosis in perimenopausal period.

Transvaginal vs transabdominal hysterectomy for cicatricial non-prolapsed uterus / 中华全科医师杂志

One hundred and ninety-three patients undergoing transvaginal hysterectomy for cicatrix uterus (study group), 200 patients receiving transabdominal hysterectomy for cicatrix uterus (control group Ⅰ), and 200 patients having transvaginal hysterectomy for non-prolapsed uterus (control group Ⅱ) were retrospectively analyzed. In comparison with the control group Ⅰ, the study group showed a significantly reduced operation time and the average volume of blood loss (P < 0.01). Moreover, patients in the study group had shorter postoperative recovery time (P < 0.01) . The incidence of postoperative fever was decreased in the study group. There was no significant difference in complications of the vaginal wound between the three groups (P 0.05). This investigation demonstrates that transvaginal hysterectomy might be feasible and safe in removing cicatrix non-prolapsed uterus.

Effects and its mechanism of quercetin on cervical cancer HeLa cells / 中华妇产科杂志

ted in a dose-dependent manner (P<0.01). Conclusion Quercetin can significantly inhibit the proliferation of HeLa cells, which may be induced apoptosis of cervical cancer cells via the Ca2+-dependent mitochondrial apoptosis pathway.
