According to the different diseases, different treatments were unde~aken. ResultsThe use of hysteroscopy could make a clear diagnosis to variety of intrauterine abnormalities, and could treat many diseases at the same time directly. ConclusionUsing hysteroscopy to diagnose and treat abnormal uterine bleeding is a reliable method.

Objective: To study self-efficacy and locus of control in s tudents under stress Method: 489 students including 138 colleg e students, 222 high school students and 129 high school students facing national examination for college (exam group) were collected SEI (self-judgement inven t ory) and ASLEC (adolescent life event scale) were applied to college students an d high school students Scale for Self-efficacy in Mathematics, ICP (inner cont r ol potential) and TAS (test anxiety scale) were applied to exam group R esult: Only in male students, there was significant negative correlation between general self-efficacy and stress The stress level of female was highe r than male There was significant negative correlation between stress and self- e fficacy in mathematics and between stress and internality While positive corre l ation existed between stress and powerful others, and between stress and chance In multiple regression, the main factors influence stress were gender, self-e fficacy and chance

BACKGROUND:The function was poor in middle aged and elderly patients with total knee replacement. If there was no ideal anesthesia during the operation, the prognosis of patients would be poor. Therefore, it is necessary to explore the analgesic drugs for artificial knee joint arthroplasty. OBJECTIVE:To investigate clinical analgesic efficacy of tramadol and paracetamol in total knee arthroplasty and the drug safety. METHODS:200 cases undergoing unilateral total knee arthroplasty in the Department of Orthopedics of Huaian First Hospital Affiliated to Nanjing Medical University from December 2013 to January 2015 were enroled in this study. According to the different methods of analgesia, patients were divided into control and experimental groups, with 100 cases in each group. Control group received intravenous patient controled analgesia. Experimental group received paracetamol and tramadol oraly. Clinical analgesic efficacy and safety of tramadol paracetamol in total knee arthroplasty were analyzed. RESULTS AND CONCLUSION: No significant difference in visual analogue scale score was detected immediately, 4 and 5 days after replacement in both groups. Visual analogue scale score was significantly lower in the experimental group than in the control group at 1-3 days after replacement. Hospital for Special Surgery scores at 7 and 12 months after replacement and Special Surgery scores at 24 and 72 hours after replacement were significantly higher in the experimental group than in the control group. The twice doses of tramadol and paracetamol were significantly lower at 24 and 48 hours after replacement in the experimental group than in the control group. The incidence of complications was significantly lower in the experimental group than in the control group. These data verify that during perioperative analgesia, the effects of tramadol and paracetamol were ideal, could lessen patient’s pain, contribute to the recovery of knee function, have less adverse reactions, and have a certain clinical application value.

The minimally invasive surgery means treatment that can remain homeostasis, reduce tissue damage, benefit body recovery and prognosis. The typical techniques of minimally invasive surgery in gynecology are laparoscope and hysteroscope, which can replace nearly all kinds of traditional gynecology surgery and have superior curative effect. After 10 years clinical practice, we found that reasonable application of laparoscope play a significant role in ensuring the surgery quality and postoperative living quality, on account of the greater risk by new surgery instruments and various sorts of energy. The popularization of gynecology minimally invasive surgery is influenced by the regional economic development and update of doctor's ideology, so it is important to train the surgeons and change their ideas.

"Triple-negative"breast cancer patients who have special clinicopathological characteristics are defined by a lack expression of oestrogen,progesterone,and HER-2 receptors.Triple-negative patients usually metastasize early with worse prognosis,and have a higher incidence of visceral metastases than bony metas tases.This subgroup has no chance of hormone treatment and targeted therapy for HER-2,and chemotherapy is the main therapy.We discuss the predominant proliferative signals,molecular features of triple-negative breast cancer,and some basic studies and clinical trials.Furthermore,targeted therapy against EGFR,C-kit,and BRCA1 may show preferable anticancer activity.However,recent research is still unable to identify the biological characteristics of triple-negative Cancer,and special treatment is still not available.
