Objective To investigate the clinical curative effect and the influence on knee joint function of knee osteoarthritis treating with sodium hyaluronate combined with compound salvia injection.Methods 78 patients with osteoarthritis treated in our hospital from June 2015 to August 2016 were randomly divided into three groups: sodium hyaluronate group, compound salvia injection group and sodium hyaluronate plus compound salvia injection combination therapy group, 26 cases each group.The levels of serum inflammatory cytokines (IL-6,TNF-αand IL-1β) were measured by ELISA before and after treatment in the three groups, and the improvement of knee joint function and the change of pain score before and after treatment were analyzed as well.Results The total effective rate of sodium hyaluronate combined with compound salvia injection was significantly higher than that of sodium hyaluronate and compound salvia injection alone ( P <0.05 ); after treatment, patients VAS pain score was significantly decreased ( P <0.05), and the VAS pain scores in the combination group were significantly lower than those of the group treated with sodium hyaluronate and the compound salvia injection (P<0.05).The levels of IL-6, TNF-αand IL-1βin the three groups were significantly lower than those before treatment (P<0.05),and the inflammatory factors in the combination group were significantly lower than those in the alone treatment group (P <0.05). Conclusion Sodium hyaluronate combined with compound salvia injection has good clinical curative effect on knee osteoarthritis,improving the function of knee joint, reducing pain and so on.

Objective To investigate the effect of erythropoietin on hemorrhage in hip replacement surgery .Methods 48 cases undergoing elective hip replacement surgery in our hospital From June 2014 to October 2016 were selected and devided into control group and experimental group according to the conditional similarity, 24 cases in each group, then the application of erythropoietin in hip replacement surgery was explored.For the experimental group, erythropoietin was injected subcutaneously at three, five and seven days before operation, the dose was 250 U/(kg· times).The control group received 0.9%sodium chloride injection of the same volume of saline, and the other treatments were the same as in the experimental group.Preoperative situation, hemoglobin (Hb) levels, blood pressure (diastolic pressure and systolic blood pressure) at one day before surgey and three, seven and 14 days after surgey were compared and analyzed.Results There were no significant difference in body weight, hemoglobin (Hb), and age between the two groups before operation.The levels of Hb in the experimental group and the control group at 3 and 7 days after operation were compared, the difference was statistically significant (P<0.05), 14 days after the surgey, Hb returned to normal in the experimental group, while the Hb level in the control group was still significantly lower than that in the control group before surgey, the difference was statistically significant (P<0.05).There was no significant difference in diastolic blood pressure and systolic blood pressure between the two groups.Conclusion Preoperative erythropoietin mobilization in patients with hip replacement surgery can reduce the amount of bleeding during and after operation , and the adverse reactions are not obvious.

Objective To study on the factors of countercurrent occured in hysterosalpingography to improve the understanding of countercurrent.Methods 180 patients who underwent hysterosalpingography due to infertility were recruited,and 63 of them who were involved in countercurrent in the process of hysterosalpingography were analyzed statistically.Results The single factor analy-sis demonstrated that such four factors of primary/secondary infertility,menstrual clean days,tubal obstruction or not,and depth of cannula were associated with countercurrent,while Logistic regression analysis indicated that the factors of menstrual clean days, tubal obstruction or not,and depth of cannula during the hysterosalpingography operation were closely related.Conclusion Counter-current are caused by the comprehensive impact of several comprehensive factors like menstrual clean day,tubal obstruction or not, and cannula operation.Therefore adequate preparation should be made before and during the operation,to reduce the occurrences of countercurrent.

Objective To investigate the diagnostic value of the combined detection of serum glial fibrillary acidic protein (GFAP)and myelin basic protein (MBP)in the patients with early brain contusion and laceration.Methods ELISA was adopted to detect serum GFAP and MBP.The one-way ANOVA analysis was adopted to conduct the comparison among groups and the q test was adopted to conduct the pairwise comparison for analyzing the differences between the brain contusion and laceration patients with the healthy population.Results The serum GFAP and MBP levels had statistically significant differences among the mild craniocerebral injury group,severe craniocerebral injury group and the healthy control (P <0.05);which had statistically signifi-cant differences between the control group and the mild craniocerebral injury group(P <0.05);which had statistically significant differences between the mild craniocerebral injury group and the severe craniocerebral group (P <0.05 );which had statistically significant differences between the control group and the severe craniocerebral injury group (P <0.05).The serum GFAP and MBP levels in the early stage of brain contusion and laceration were significantly higher than those in the control group,moreover,the more severe the injury,the more obvious the increase of serum GFAP and MBP.Conclusion The combined detection of serum GFAP and MBP can be regarded as the auxiliary indexes for the early diagnosis of early brain contusion and laceration and the eval-uation of the injury degree.

Objective To investigate the application of multi-sliced CT on breast cancer and early lymph node metastasis (LNM). Methods 30 cases with infiltrative ductal carcinoma (IDC)confirmed by pathology were collected and set as Study Group,30 fibro-mas as Control Group.128-slice CT plain and 2 phrase enhance scan was undergone.Image signs of mass of two groups were com-pared.Image signs of early lymph node metastasis were analyzed.Results In MSCT images,IDC masses had irregular shape,burr rim.2-phrase MSCI demonstrated obvious enhancement in artery phrase,persistence enhancement in vein phrase and ring shape en-hancement.There were significant different between 2 groups in mass shape,rim and enhancement mode(P<0.05).MSCT demon-strated 22 LNM,but 6 of them had no swelling but obvious enhancement.Conclusion 2-phrase MSCT plays an important role in as-sessing breast cancer and early lymph node metastasis.

Objective To explore the value of low-dose CT in assessment of neonatal pneumothorax.Methods Low-dose CT and chest radiographys were performed in 98 neonates with clinically suspected of pneumothorax.Results Pneumothorax was detected in 98 neonates by low-doseCT, compared with 84 neonates by chest radiography.The sensitivity of low-dose CT was higher than that of chest radiography (P =0.026<0.05). Conclusion Low-dose CT provides a reliable assessment of neonatal pneumothorax and a guide for clinical diagnosis and treatment.

Objective To evaluate the influence of preoperative MRI on tumor-positive rate of resection margins in breast cancer patients eligible for breast-conserving surgery.Methods Study group consisted of 64 consecutive patients with breast cancer eligible for breast-conserving surgery,while 73 cases as history control group.For the two groups,a first plan for breast-conserving surgery was made on the basis of conventional imaging and clinical evaluation.Study group underwent preoperative breast MRI and re-evalu-ated before final surgical plan was made.Rates of tumor-positive resection margins were compared between the 2 groups.Surgical plan alteration was recorded in the study group.Results Study group had lower rate of tumor-positive resection margin compared with control group (9.6% vs 24.7%,P =0.04).Furthermore,18.8% of study group altered the finial surgical plan to mastectomy after breast MRI.Conclusion Preoperative breast MRI can more acurately evaluate the extent of breast cancer,therefore decrease rate of tumor-positive resection margin in breast cancer patients eligible for breast-conserving surgery.

Objective To investigate the diagnostic value of nuron specific enolase( NSE),S100βprotein,glial fibrillary acidic protein( GFAP)and myelin basic protein( MBP)in patients with early brain contusion and laceration. Methods One hundred and twelve cases with brain contusion and laceration diagnosed by CT or MRI were selected as our subjects who hospitalized Harrison international peace hospital from Apr. 2012 to Jul. 2013. Of them,68 cases with mild head injury were served as mild group and 44 cases of severe traumatic brain injury were served as severe group. And 83 healthy people without lung disease and nervous system diseases were served as control group. Electro chemiluminescence assay and ELISA methods were used to measure the level of NSE,S100β,GFAP,MBP. Results the level of serum NSE,S100β protein,GFAP and MBP in mild group were(18. 14 ± 6. 83),(0. 92 ± 0. 45),(0. 78 ± 0. 37))(4. 37 ± 1. 84)μg/ L,respectively, and(32. 11 ± 12. 48),(1. 58 ± 0. 94),(4. 26 ± 1. 96),(14. 72 ± 6. 77)μg/ L,respectively in severe group, and(8. 94 ± 3. 49),(0. 12 ± 0. 08),(0. 13 ± 0. 09),(1. 98 ± 0. 89)μg/ L,respectively in control group. There were significant differences among three groups( F = 137. 520,120. 083,283. 727,205. 569 respectively;P< 0. 01). All indexes were different between control and mild groups( q = 10. 599,13. 296,5. 881,6. 018;P< 0. 01),as well as between the mild and severe groups(q = 13. 600,9. 249,26. 639,22. 029;P < 0. 01),and between control and severe group(q = 23. 408,21. 258,32. 797,28. 134;P < 0. 01). Conclusion The level of serum NSE,S100β,GFAP,MBP can be used as early indicators of brain injury secondary diagnosis and secondary index for evaluating damage degree.
