Recent treatment progress of triple negative breast cancer.

Breast cancer (BC) is a serious worldwide disease that threatens women's health. Particularly, the morbidity of triple-negative breast cancer (TNBC) is higher than that of other BC types due to its high molecular heterogeneity, metastatic potential and poor prognosis. TNBC lacks of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2), so there are still no effective treatment methods for TNBC. Here, we reviewed the classification of TNBC, its molecular mechanisms of pathogenesis, treatment methods and prognosis. Finding effective targets is critical for the treatment of TNBC. Also, refining the classification of TNBC is benefited to choose the treatment of TNBC, because the sensitivity of chemotherapy is different in different TNBC. Some new treatment methods have been proposed in recent years, such as nutritional therapy and noncoding RNA treatment methods. There are some disadvantages, such as the side effect on normal cells after nutrient deprivation, low specificity and instability of noncoding RNA. More studies are necessary to improve the treatment of TNBC.

Needle Sensation and Personality Factors Influence Therapeutic Effect of Acupuncture for Treating Bell's Palsy: A Secondary Analysis of a Multicenter Randomized Controlled Trial / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>It has not been solved what kind of needle sensation might influence outcomes of acupuncture treatment. Effects of personality factors on the therapeutic effect of acupuncture have not been investigated. This study aimed to find the effects of the traits of personality on the objective outcome when different acupuncture techniques were used in treating patients with Bell's palsy.</p><p><b>METHODS</b>We performed a secondary analysis of a prospective multicenter randomized controlled trial of acupuncture for Bell's palsy. Patients were randomly assigned to the de qi and control groups, respectively. The primary outcome was facial nerve function at month 6. The intensity of each needle sensation was rated by a visual analog scale. Psychosocial factors were assessed by the pretreatment mediator questionnaire; 16 Personality Factor Questionnaire (16PF) was used for assessing personality factors and digit cancellation test for assessing attention.</p><p><b>RESULTS</b>After 6 months, patients in the de qi group had better facial function (adjusted odds ratio [OR]: 4.16, 95% confidence interval [CI]: 2.23-7.78). Path analysis showed that intensity of needle sensation of fullness had direct effect on House-Brackmann (HB) score at month 6. In de qi group, the low HB score on day 1 (OR: 0.13, 95% CI: 0.03-0.45) and the low Social Boldness score (OR: 0.63, 95% CI: 0.41-0.97) in 16PF were associated with better facial function. In control group, low HB score on day 1 (OR: 0.25, 95% CI: 0.13-0.50), low Vigilance score (OR: 0.66, 95% CI: 0.50-0.88), and high Tension score (OR: 1.41, 95% CI: 1.12-1.77) in 16PF were related to better facial function.</p><p><b>CONCLUSIONS</b>The needle sensation of fullness could predict better facial function and personality traits might influence outcomes of acupuncture treatment. Both of them should be considered seriously in acupuncture treatment and research.</p>

[Clinical risk factors for deep vein thrombosis after total hip and knee arthroplasty].

OBJECTIVE: To analyze the clinical risk factors for deep vein thrombosis (DVT) after total hip and knee arthroplasty in Chinese patients who received prophylactic treatment for DVT. METHODS: We evaluated 128 total hip arthroplasty (THA) and total knee arthroplasty (TKA) in 95 patients performed at our center from April 2004 to August 2004, which included 48 THAs in 43 patients and 80 TKAs in 52 patients. There were 27 men and 68 women with a mean age of 59.77 years (range, 23-78 years). All patients had been given low-molecular-weight heparin before operation and for 7-10 days post-operation to prevent DVT. Color Doppler ultrasonography was used to detect DVT of bilateral lower extremities in all patients before operation and at 7-10 days after operation. Nineteen clinical factors were examined preoperation and 7-10 days post-operation in order to analyze their influences on DVT formation after surgery. RESULTS: There were 45 patients who developed DVT after operation. The incidence of DVT in all patients was 47.4% (45/95) and the incidence of proximal DVT was 3.2%. There were more asymptomatic DVT (57.8%, 26/45) than symptomatic ones, and some patients without DVT (14%, 7/50) presented some of the DVT symptoms. Logistic regression analysis demonstrated a definite association of female, obesity (representative by BMI), cement usage and diagnosed RA with DVT with odds ratio of 10.008, 3.094, 8.887, and 0.194 respectively. Other clinical factors had no statistically significant association with DVT. CONCLUSIONS: Female, obesity, and cement usage were the risk factors for DVT after THA and TKA, and diagnosed RA was the protecting factors for DVT after THA and TKA. Other clinical factors such as age, OA, type of implant, monolateral or bilateral operation, duration of anesthesia, surgery and bandage usage for blood control, time for immobilization et al were not the risk factors for DVT.
