Objective:To explore the effect of continuous obstetric-pediatric cooperative nursing on anxiety, depression and the parenting sense of competence in NICU premature mothers.Methods:Totally 140 mothers of NICU preterm infants in hospital from January 2018 to December 2018 were selected and randomly divided into the control group and intervention group according to the method of random number table, and each group 70 cases. The control group received the routine nursing mode in obstetrics and paediatrics and the intervention group received the continuous obstetric-pediatric cooperative nursing based on routine nursing. To compare the anxiety level, depression level, the score of parenting sense of competence, hospitalization days of preterm infants, the outpatient rate and the readmission rate of preterm infants within 1 months of discharge between two groups.Results:The levels of anxiety and depression of the mothers of premature infants in the intervention group during hospitalization ,1 week after discharge and 1 month after discharge were (43.17±6.89), (8.96±2.67), (34.65±6.87), (7.65±1.92), (34.97±6.06), (6.29±1.54) points, lower than control group (47.03±8.06), (10.97±3.34), (45.44±7.72), (9.43±2.61), (41.46±7.26), (8.28±2.23) points, the differences between the two groups showed statistical significance ( t value was 2.331-6.097, P<0.05). The two dimensions of parenting efficacy and parenting satisfaction were (31.47±4.97), (43.38±4.21) points, which were higher than (25.91±5.42), (39.43±5.91) points of the control group, there were significant statistical differences among the two groups ( t value was -6.314 and -4.528, P<0.01). The hospitalization days of premature infants, outpatient and readmission rate within 1 month of discharge were (13.25±3.27) days, 8.57% (6/70), 2.86% (2/70), which were shorter or lower than (15.59±2.79) days, 24.29% (17/70), 12.86% (9/70) in the control group, the differences were statistically significant ( t value was 2.909, χ2 values were 6.295, 4.834, P<0.05). There were significant statistical differences among interaction effect, time effect and intergroup effect ( F values were 4.921-99.310, P<0.05). Conclusion:Obstetrical-pediatric cooperative nursing can effectively to lower the anxiety and depression level of preterm mothers, improve the parental competence, promote the mental health of preterm mothers, and ultimately shorten hospital days and decrease the rate of outpatient and readmission of premature infants, which is conducive to preterm infants′ rehabilitation.

Objective To review the clinical data and visual outcomes after treatment of patients with dysthyroid op-tic neuropathy ( DON) .Methods We retrospectively examined the clinic data of the 38 patients (67 eyes) suffer-ing from DON and analysed the effect of glucocorticoids , radiation and orbital decompression .Results The study included 14 men and 24 women.32 patients ( 84.2%) received multiple treatment modalities .LogMAR vision acuity changed from (0.60 ±0.59) before treatment to (0.18 ±0.09) after treatment(P<0.01) .There were 59 eyes (88.1%) in the treatment effective group , 8 eyes (11.9%) in the ineffective group .38 eyes underwent ini-tial treatment with intravenous steroid pulse therapy and 35 eyes ( 92.1%) were effective .29 eyes were treated with other modalities and 24 eyes(82.8%) were effective(P<0.01).There were 3 eyes (5.1%) suffering from fixed eyeball movement in the effective group , while 4 eyes ( 50%) in the ineffective group ( P <0.05 ) .The thickness of the supraocular muscle group in the effective group was (7.63 ±1.19 ) mm, (8.81 ±0.83 ) mm in the ineffective group (P<0.05).Mean defect of the visual field was (2.41 ±2.82) in the effective group and (11.98 ± 7.07 ) in the ineffective group ( P<0.05 ) .Conclusions Treatment with multiple modalities effectively improved visual outcomes in cases of DON .Intravenous pulse steroid therapy was recommended as the initial modality .

Objective To explore the level of Th2 type cytokines including IL-4, IL-10 and IL-13, and the immunoreg-ulation of cytokines in patients with neurocysticercosis. Methods Lymphocytes in patients with neurocysticercosis were separated from the blood sample with density gradient centrifugation and the total RNA was extracted by guanidine isothiocynate method. cDNA was synthesized by reversed transcription reaction. The target gene was then amplified by PCR. The PCR products were analyzed by electrophoresis. Results Results of RT-PCR showed that cytokines mRNA in lymphocytes of peripheral blcod were detected in 27 patients with neurocysticercosis but not in the other 3 cases. Among the positive cases, mRNA of IL-4, IL-10 and IL-13 was detected in 16, 17 and 14 cases respectively and mRNA of IL-4, IL-10 and/or IL-13 was detected in all the 27 cases. In the detection of lymphocytes in peripheral blcod of 10 healthy subjects, expression of IL-4 and IL-10 was found in only one case at low level. Conclusion The study revealed that Th2 associated cytokines were expressed at high level and the humoral immunocompetence was relatively strong in patients with neurocysticercosis.

We studied the actions of diffusion weighted imaging (DWI) and dynamic contrast enhanced (DCE) magnetic resonance imaging (MRI) in differentiating breast tumors. From January 2010 to February 2012, we retrospectively analyzed data of 95 cases with breast tumor pathologically confirmed from DWI and DCE-MRI. We compared the ADC value, time-intensity curve (TIC) and DCE-MRI parameters between breast tumors, and calculated the sensitivity and specificity for differentiating breast tumors. The results were as follows: (1) On DWI, mean ADC value of malignant tumor was lower than that of benign tumor (P < 0.05). For differentiating breast malignant tumors from benign neoplasm, a cut-off ADC value of 1.2 x 10(-3) mm2/s achieved a sensitivity of 74.1% and specificity of 70.3%. (2) On DCE-MRI, early enhancement ratio (EER) value of malignant tumor was higher than that of benign tumor whereas value of time to peak (Tpeak) and maximal enhancement ratio (SImax) were lower than that of benign tumor (all P < 0.05). As for TIC, type II and III were more frequently seen in malignant tumor than in benign tumor whereas type I was more common in benign tumor than in malignant tumor (all P < 0.05). For differentiating breast malignant tumors from benign neoplasm, DCE-MRI obtained a sensitivity of 89.7% and specificity of 70.3%. (3) For differentiating breast malignant tumors from benign neoplasm, ADC value together with TIC obtained a sensitivity of 79.3% and specificity of 78.4%. Malignant or benign breast tumors could have their own unique characteristics on DWI and DCE-MRI. These characteristics might be helpful for differentiating these tumors.

Calcineurin inhibitor screening should benefit from the strengths of each method. This paper reviews three calcineurin inhibitor screening methods:yeast positive screening model, yeast reporter gene high through- put screening model and calcineurin activity detection method. We have compared the range of application, advantages and disadvantages of each method, and combined effect of multiple methods. The yeast positive screening model can prevent the false positiveness caused by bacteriostat by using growth zooms instead of inhibition zooms. The yeast reporter gene high through-put screening model is suitable for pilot screening among a wide range of samples and is more efficient than the other methods. The calcineurin activity detection method can directly report the inhibitory ratio to a specific target. This review is expected provide a model-selection reference for the development of novel low-toxic calcineurin inhibitors.

Objective To evaluate the method and clinical effect of subtalar joint distractor assisted open reduction and internal fixation of comminuted intra-articular calcaneal fracture.Methods Twenty-two patients with fresh closed calcaneal fracture treated with open reduction and internal fixation from May 2011 to July 2013 were included in the study.According to the modes of operation,the patients were randomly divided into two groups (n =11 in each):in group A patients underwent fracture reduction assisted by subtalar joint distractor and in group B patients underwent Steinmann pin traction and poking reduction.All were fixed using the lateral calcaneal plate.Operation time,B(o)hler angle,Gissanes angle,calcaneus height,incision healing time and complications of the two groups were investigated for evaluating the effect of operation.Clinical effect was evaluated using the American Orthopedic Foot & Ankle Society (AOFAS) score before the removal of internal fixation.Results Period of follow-up was (14.3±0.8)months (range,12 to 18 months).Two patients in group B had delayed wound healing,and were treated with regular wound care.At the final follow-up,no infection,nonunion,malunion and internal fixation failure were observed.B(o)hler angle,operation time and calcaneus height observed in group A were superior to those in group B (P ＜0.01).There was no significant difference in Gissanes angle between the two groups (P ＞ 0.05).Compared to the preoperative data,B(o)hler angle,Gissanes angle and calcaneus height were significantly improved in both groups (P ＜0.01).AOFAS score was (83.6 ± 1.4) points in group A and (81.7 ± 1.5) points in group B.Conclusion Subtalar joint distractor assisted open reduction and internal fixation is effective to shorten operation time,improve fracture reduction,reduce wound complications and increase the operative effect for comminuted intraarticular calcaneal fracture.

Objective To analyze the correlation between gross motor function and activities of daily living(ADL)in children with cerebral palsy.Methods 42 children with CP(26 males,16 females,average age 49.5±21.5 months,11 children with spastic quadriplegia,22 with spastic diplegia,5 with spastic hemiplegia,2 with athetosis and 2 with dystonia)were assessed with Gross Motor Function Classification System(GMFCS)and Gross Motor Function Measure(GMFM)for the assessment and classification of gross motor function.Pediatric Evaluation of Disability Inventory(PEDI)was used to assess the ADL.The ADL of children with different levels of GMFCS and the correlation between gross motor function and ADL were analyzed.Results The more severe of GMFCS,the less standard score of PEDI.There was the highest correlation between the GMFM66 scores and scaled scores of PEDI in mobility and social function(r=0.84),whereas a weaker correlation appeared between GMFM66 scores and scaled scores of PEDI in social function(r=0.72).Conclusion Since the gross motor function of children with CP greatly affects the ADL,the gross motor function training should be the main item for CP children,the training goal of ADL should be made according to the levels of GMFCS.

OBJECTIVE:To investigate the effects of puerarin on bone mineral density around the femoral prosthesis of el-derly women after osteoporotic fracture artificial hip joint replacement. METHODS:99 elderly women after osteoporotic fracture artificial hip joint replacement were divided into control group(49 cases)and test group(50 cases)according to random number table. Control group received conventional treatment:calcium carbonate and vitamin D3+alendronate sodium+salmon calcitonin;test group was additionally given Puerarin injection 200-400 mg dissolved in Glucose injection 500 ml intravenously,qd,on the basis of control group. A treatment course lasted for 20 d,and both groups received 2 courses of treatment. The hip joint function score and bone mineral density around the femoral prosthesis of 2 groups were observed and compared after surgery,and the oc-currence of ADR was also observed. RESULTS:3 and 2 patients withdrew from control group and test group,respectively. 18 months after surgery,the patients with hip joint function score ranged 70-79 in test group was significantly less than in control group;the rate of excellent hip joint function score in test group was significantly higher than in control group,with statistical significance (P<0.05). 15 and 18 months after surgery,bone mineral density in R1-R5 range of Gruen range in test group was slightly higher than in control group,without statistical significance(P>0.05);bone mineral density in R6-R7 range was signifi-cantly higher than control group(89.58% vs. 69.57%),with statistical significance(P<0.05). The prosthesis loosening was not found in both groups,and ADR was also not found as fever,erythra,nausea,vomiting,headache,dizziness,etc. CONCLU-SIONS:For the use of puerarin in elderly women after osteoporotic fracture artificial hip joint replacement,puerarin can increase the periprosthetic femur bone mineral density with good safety.

BACKGROUND:In recent years, there are many animal studies and osteoblast studies on the anti-osteoporotic effects of puerarin, a kind of phytoestrogen. But few of them are reported on the effects of puerarin on osteoblasts in older patients with osteoporosis. OBJECTIVE: To observe the influence of puerarin on the proliferation ofin vitro cultured osteoblasts from older female patients with osteoporosis. METHODS:The older female patients with osteoporotic femoral neck fractures who underwent artificial femoral head replacement were included in this study. The femoral neck cancelous bone removed during the operation was colected. Primary cancelous bone osteoblasts were cultured using explant culture method. The cels were sub-cultured to the required amounts. Osteoblasts from the control group were cultured with culture medium without puerarin. Osteoblasts from the 0.01, 0.1, and 1 μmol/L puerarin groups were cultured with culture medium containing the corresponding concentrations of puerarin. After in vitro co-culture with different concentrations of puerarin for 1, 3, 5 days, the proliferation of osteoblasts was observed. RESULTS AND CONCLUSION:With the increase in the concentration of puerarin, the proliferative activity of
osteoblasts constantly increased at different time points (P < 0.05). At 3 days of culture, cel absorbance value in each group reached the peak level. These results suggest that 0.01, 0.1, 1μmol/L puerarin promotes the proliferation of osteoblasts in older patients with osteoporosis in a concentration-dependent manner.
