Effect of mindfulness-based childbirth on pregnant women with anxiety and depression disorders / 四川精神卫生

ObjectiveTo explore the effect of mindfulness-based childbirth on pregnant women's anxiety and depression， and to provide references for related psychological intervention. MethodsA total of 80 pregnant women who attended the obstetrics department of the Third People's Hospital of Mianyang from October 2018 to March 2019 and met the diagnostic criteria of mild to moderate anxiety and depression in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） were selected， and they were divided into two groups by random number table method， each with 40 cases. Both groups received regular mental health education. On this basis， experimental group received mindfulness-based childbirth training for 8 times， once a week. Meantime， all pregnant women were assessed using Patient Health Questionnaire-9 item （PHQ-9） and Generalized Anxiety Disorder Scale （GAD-7） at the baseline and after intervention. ResultsAt the baseline and after intervention， the scores of PHQ-9 ［（6.95±1.40） vs. （2.10±1.34）， P<0.05］ and GAD-7 ［（7.23±1.29） vs. （2.08±1.51）， P<0.05］ in the experimental group had statistical significance， and the scores of PHQ-9 ［（7.00±1.43） vs. （3.65±1.35）， P<0.05］ and GAD-7 ［（7.18±1.57） vs. （3.38±1.66）， P<0.05］ in the control group had statistical significance. Moreover， the post-intervention scores of PHQ-9 and GAD-7 were significantly lower in experimental group than in control group （t=5.161， 3.666， P<0.01）. ConclusionCompared with mental health education alone， its combination with mindfulness-based childbirth achieves better effect in alleviating the anxiety and depression status of pregnant women.

Chronic myelomonocytic leukemia complicated with Sweet 's syndrome developed into acute myelomonocytic leukemia: a case report and review of the literature / 白血病·淋巴瘤

ObjectiveTo improve the understanding of chronic myelomonocytic leukemia associated with Sweet' s syndrome.MethodsRetrospective analysis of a case of chronic myelomonocytic leukemia associated with skin herpes was reported. Skin biopsy was performed. DA and CAG regiment were administrated.ResultsSweet's syndrome was diagnosed by skin biopsy.Corticosteroids therapy alone was not effective. Complete remission was achieved by CAG regiment and skin rash has been effectively controlled.Three months later Sweet' s syndrome relapsed and chronic myelomonocytic leukemia developed into acute myelomonocytic leukemia. ConclusionChronic myelomonocytic leukemia associated with Sweet's syndrome is rare but implies a quick progression to acute myelomonocytic leukemia.

The management of severe vascular injuries caused by stripping of great saphenous vein varicosis / 中华普通外科杂志

Objective To summarize our experience on the treatment for severe vascular injuries in the operation of great saphenous varicose vein. Methods The clinical data of 4 cases (5 lower limbs) from December 2004 to April 2009 of severe vascular injuries were retrospectively analyzed. For the lower limbs in which from the end of femoral artery to the upper part of posterior tibial artery were stripped, reconstruction operation using blood vessel prothesis was performed, above knee amputation was performed because of limb gangrene. For three limbs in which 10 cm to 15 cm superficial femoral artery were stripped, reconstruction operation using autologous saphenous vein were performed, above knee amputation was performed for one limb 5 days after the operation. For the limb in which 2 cm superficial femoral vein were cut, reconstruction operation using autologous saphenous vein were performed. Results No cases died perioperatively,for four limbs of injuried artery, ampution were performed for two limbs(50% ) ;two limbs (50%) were saved. The patient of injuried superficial femoral vein recovered. Conclusions Severe vascular injuries can be prevented and its incidence reduced by improving the awareness for iatrogenic vascular injuries,accurate operation; once the vascular injury occurred, prompt and rational measures must be adopted.

Rule induction algorithm for brain glioma using support vector machine / 生物医学工程学杂志

A new proposed data mining technique, support vector machine (SVM), is used to predict the degree of malignancy in brain glioma. Based on statistical learning theory, SVM realizes the principle of data dependent structure risk minimization, so it can depress the overfitting with better generalization performance, since the prediction in medical diagnosis often deals with a small sample. SVM based rule induction algorithm is implemented in comparison with other data mining techniques such as artificial neural networks, rule induction algorithm and fuzzy rule extraction algorithm based on fuzzy max-min neural networks (FRE-FMMNN) proposed recently. Computation results by 10 fold cross validation method show that SVM can get higher prediction accuracy than artificial neural networks and FRE-FMMNN, which implies SVM can get higher accuracy and more reliability. On the whole data sets, SVM gets one rule with the classification accuracy of 89.29%, while FRE-FMMNN gets two rules of 84. 64%, in which the rule got by SVM is of quantity relation and contains more information than the two rules by FRE-FMMNN. All the above show SVM is a potential algorithm for the medical diagnosis such as the prediction of the degree of malignancy in brain glioma.
