Objective To observe the effect of breast massage and sticking therapy on maternal lactation and breast swelling of puerperae. Methods According to delivery sequence number, four hundred puerperae were randomly divided into two groups with 200 cases in each group. The control group only received the breast massage, and the experiment group received both breast massage and sticking therapy for 3 days. The breast swelling and maternal lactation volume were compared and observed. Result The degree of breast swelling in the experiment group was significantly lower than that in the control group and the maternal lactation volume was significantly larger than that in the control group (P<0.05). Conclusion The breast massage plus sticking therapy can promote maternal lactation and reduce breast swelling and therefore it is worthy of popularization and application.

BACKGROUND:Knee joint function limitation often occurs after internal fixation of complex femoral condyle fractures, but the mechanism and its influencing factors are also unclear.
OBJECTIVE:To screen and analyze the relevant factors of knee joint function limitation after internal fixation of complex femoral condyle fractures.
METHODS:We retrospectively summarized postoperative fol ow-up data of 6 and 12 months from 121 patients with complex femoral condyle fractures. Knee joint function recovery was evaluated according to Merchan criteria. A multiple stepwise regression analysis was carried out in terms of gender, age, causes, concomitant injuries, skin and soft tissue injury, fracture type, fixed method, operation time, postoperative plaster fixed situation, healing of postoperative incision, bone healing and postoperative functional exercises, to summarize the relevant influencing factors for knee joint function limitation.
RESULTS AND CONCLUSION:Whether the knee joint function after internal fixation was limited acted as the dependent variable Y, and factors with statistical significance of the single factor analysis served as the independent variable X. We used the multiple stepwise regression analysis for multiple factors analysis. Results showed that the gender of patients (X1), with or without concomitant injuries (X3), soft tissue damage (X4) and operation time (X6), a total of four factors, could not be introduced into the model, suggesting that these four factors had no significant correlation with postoperative knee joint function limitation. Another eight factors could be introduced into the factor analysis model, showing that the cause of injury (X2), fracture type (X5), the choice of internal fixation (X7), with or without bone graft (X8), with or without postoperative plaster cast (X9), postoperative knee joint functional exercise or not (X10) and postoperative wound healing (X11), the degree of postoperative bone healing (X12) are closely related to postoperative knee joint function limitation in complex femoral condyles fractures.

BACKGROUND:Vertebroplasty with bone cement injection can achieve a correction of kyphosis, enhancement of vertebral strength, and elimination of vertebral lesions during reduction of the fracture. OBJECTIVE: To analyze the efficacy of vertebroplasty with bone cement injection on osteoporotic vertebral compression fracture. METHODS:Totaly 84 patients with osteoporotic thoracolumbar vertebral compression fractures (T6-L4), 37 males and 47 females, aged 58-80 years, were randomized into two groups: study group undergoing vertebroplasty with bone cement injection and control group subject to bed rest and conservative treatment (functional exercise of the back muscle). Visual analog scale score, Oswestry disability index and vertebral height were detected and compared between the two groups before and after treatment. RESULTS AND CONCLUSION:There was no difference in vertebral height, visual analog scale score and Oswestry disability index between the two groups before treatment. At 3 months after treatment, the vertebral height was (1.653±0.168) cm in the study group and (1.521±0.200) cm in the control group, with a significant difference (P< 0.05). The visual analog scale scores and Oswestry disability index scores in the study group were both lower than those in the control group at 3 months after treatment and at the last folow-up (P < 0.05). After treatment, there were two cases of pressure sores, three cases of deep venous thrombosis, one case of pneumonia and two cases of urinary tract infections in the control group; while only 4 cases developed bone cement leakage in the study group, but with no obvious clinical symptoms. No difference in re-fracture rate occurred between the control group (n=3) and study group (n=4;P > 0.05). These findings suggest that the bone cement injection as vertebral augmentation therapy can rapidly relieve pain, improve patients' quality of life within a short term and restore the vertebral height in patients with osteoporotic vertebral compression fractures.

Objective To understand the occurrence situation of negative life events in the past year among college students with suicidal ideation and to explore the correlation between negative life events and suicidal ideation. Methods The stratified and cluster sampling method was applied to conduct the questionnaire survey on 12 114 students from 11 universities in Chongqing City. The questionnaire of general demographic information was used to learn sociodemographic characteristics;the perspective on personal life questionnaire was applied to evaluate the suicidal ideation within recent 1 month and the self-designed life event scale was used to investigate the occurrence of negative life events in the past 1 year. Results The report rate of suicidal ideation within 1 month was 9.6%, the occurrence rate of short term suicidal ideation was increased with experiencing more negative life events. The x2 test showed that there was statistically significant difference in the proportion of suicidal ideation occurrence between college students experiencing 1 negative life event and those without experiencing the negative life event (x2 = 37.72,P<0.01) ;besides, the occurrence proportion of recent suicidal ideation had statistical difference between the college students with experiencing two or more negative life events and those without experiencing negative life event (x2 = 65.46,P<0.01). The multivariate Logistic regression analysis showed that the conflict with other family members (OR=0. 295,95%CI 0. 017-0. 571),abuse (OR=7. 295, 95%CI 6. 049-9. 701) were independentrisk factor for the recent suicidal ideation in college students. Conclusion Experiencing more negative life events, conflicting with other family members and abused by others have a correlation with the appearance of short term suicidal ideation in college students.
