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.

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.

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

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.

Objective To explore the clinical manifestations, electroencephalographic characteristics and therapeutic effect of drugs in children with Jeavons syndrome. Methods The clinical and electroencephalographic characteristics and thera-peutic effect of drugs were analyzed in 4 children with Jeavons syndrome. Results Among the four children there were 3 female and 1 male. The age at the onset of the disease was from 1 to 6 years. The typical clinical manifestations of this disease were brief, fast and repeated eyelid myoclonia (EM) with or without absence seizure. The typical electroencephalography (EEG) in two patients showed 3-6 Hz generalized spike and waves and polyspikes burst, and the eye closure and intermittent photic stimu-lation helped to induce discharges and clinical events. The typictal EEG in the other two patients showed 3.0-3.5 Hz generalizedδslow wave rhythm burst. The drugs of choice for treatment was sodium valproate monotherapy in two cases, levetiracetam in one case, sodium valproate combined with levetiracetam in one case. During the follow-up, seizures were controlled in one case, decreased in frequency in two cases and were still frequent in one case. Conclusions Jeavons syndrome is one of the idiopathic and generalized epileptic syndromes and characterized by EM with or without absence seizure. Video EEG monitoring plays an important role in the diagnosis of this disease. Sodium valproate and levetiracetam were effective for this disease.

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.

Objective To evaluate MRI findings and X ray appearance in primary myelofibrosis (PMF) in marrow of lumber vertebra and pelvis. Methods Eleven cases of PMF with integrated clinical and pathology data were collected. All cases were examined with X ray and MRI simultaneously. The imaging findings of PMF were studied and compared with that of normal group. The MRI findings and X ray appearance of cases with PMF were evaluated and compared with each other to find their good quality, the shortcoming, and the relationships. Results X ray appearance in the plain film in cases with PMF: There were no abnormal findings in lumbar vertebra, iliac bone, and superior segment of femur in 5 of 11 cases. Blurred bone trabecula and ground glass changes in bone marrow were found in 3 of 11 cases. In another 3 cases, the bone trabeculas were obscured, tightly closed or mixed together, and the density of bone marrow were widespreadly high, and the difference in it couldn′t be distinguished. MRI findings in cases with PMF: MRI findings in different parts of lumbar vertebrae, iliac bone, and femur superior segments in all 11 cases were consistent. Compared with the control group, both images on T 1 and T 2 weighted spin echo displayed diffusely and well distributed lower signal intensity in 6 of 11 cases, but displayed scattered spot and patchy lowersignals in 5 of 11 cases in all parts of bone marrow including lumbar vertebra, iliac bone, and superior segment of femur. The extents of lower marrow signal intensity varied in different cases. The high signal in femoral head and greater trochanters remained unchanged as that of subcutaneous fat in 4 of 11 cases. The positive rate was 54.6%(6/11)in X ray findings, but 100%(11/11)in MRI appearances. Conclusion MRI has greater value than X ray in the early diagnosis of PMF. The early diagnostic value of X ray plain film for PMF is limited.

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.

Objective To evaluate the change of left ventricular diastolic function and investigate the relation between left ventricular diastolic function and disease activity in rheumatoid arthritis (RA) without clinical manifestations of heart diseases. Methods Seventy consecutive active RA in-patients without clinical manifestations of heart disease were enrolled, while the control group was recruited from outpatient health physical check-up center and consisted of 60 age- and sex-matched healthy subjects. Cardiac related parame-ters were determined by echocardiography and the correlation between left ventricular diastolic function and the disease activity indexes were evaluated. Chi-square test, t test, Pearson or Spearman′s correlation test and Stepwise backward linear regression analysis were used for statistical analysis. Results RA patients had lower mitral inflow E/A ratio (1.2±0.4, 1.5±0.4, P<0.01), higher E/Em ratio (9.6±3.7, 7.8±2.0, P<0.01), longer isovolumetric relaxation time(IVRT)[(64±16) ms,(58±16) ms, P<0.05] than control group. Whilst, RA patients had higher pulmonary venous inflow A wave velocity-time integral (ArVTI) and A wave duration (DAr)[3.2±0.7,(2.8±0.6) cm; 117±11,(102±9) ms, P<0.05]. Moreover, the E/Em was positively corre-lated with C-reactive protein(CRP)(r=0.581, P<0.01), DAS28(r=0.456, P<0.01). Anti-CCP level was also associated with Em and early diastolic pulmonary venous inflow peak velocity(PVD)(r=-0.359, P<0.05;r=-0.305, P<0.05). In addition, multivariate analysis also revealed that there was linear regression relation-ship between E/Em and CRP, DAS28(t=3.266, P=0.002; t=2.949, P=0.005). Conclusion The study has revealed that left ventricular diastolic function is impaired in RA patients and the left ventricular diastolic function parameters is associated with the disease activity indexes. These results suggest that the decline of left ventricular diastolic function is associated with the inflammation activity in RA patients without clinical manifestations of heart disease.

Objective To compare the effects of moderate and deep hypothermic circulatory arrest (DHCA) during aortic arch surgery in the adult patients,to offer the evidence for the detection of which temperature provides best brain protection in the subjects who accept the great aortic surgery.Methods A total of 109 patients undergoing the surgery of aortic arch were divided into the moderate hypothermic circulatory arrest group and deep hypothermic circulatory arrest group.We recorded the characters of the patients and their cardiopulmonary bypass time,aortic clamping time,cerebral perfusion time and postoperative recovery time,tracheal intubation time,time of intensive care unit (ICU) and postoperative cognitive dysfunction.Results Patients' characteristics were similar in two groups.All the patients were cured.There were no significant differences in aortic clamping time of each group [(111.4 ± 58.4) min vs.(115.9 ± 16.2) min];selective cerebral perfusion time [(27.4 ± 5.9) min vs.(23.5 ±6.1) min] of the moderate hypothermic circulatory arrest group and deep hypothermic circulatory arrest group.There were significant differences in the cardiopulmonary bypass time[(207.4 ± 20.9) min vs.(263.8 ± 22.6) min],the postoperative recovery time [(19.0 ± 11.1) h vs.(36.8 ± 25.3) h],intubation time [(46.4 ± 15.1) h vs.(64.4 ± 6.0)h];length of ICU [(4.7 ± 1.7) d vs.(8.± 2.3) d],and postoperative cognitive dysfunction of the two groups.Conclusion Compared to the deep hypothermic circulatory arrest,the moderate hypothermic circulatory arrest can provide better brain protection and achieve good clinical results.
