Objective To study the relationship between metalloproteinases (MMPs) and breast cancer. Methods The literature in recent years on the relationship between the expression of MMPs and breast cancer was reviewed. Results The balance between MMPs and tissue inhibitors of metalloproteinases (TIMPs) is keeping normally kept in human body. Many of the studies showed that the expression of MMPs is increased in breast cancer. Conclusion The growth, invasion and metastasis of breast cancer is closely related with the increased expression of MMPs. This suggests that MMPs is a valuable prognostic marker and TIMPs would be a novel drug against cancer.
ObjectiveTo analyze the follow-up data of colorectal cancer in the Database from Colorectal Cancer (DACCA).MethodsThe information in the Dacca database was screened, and the one whose operative date and follow-up date were not blank in the total data was selected. The follow-up data were analyzed, including length of follow-up, survival outcomes, coping styles (doctors’ attitude and reaction for follow-up), follow-up path (whether to choose out-patient, Wechat, QQ tools, phone call, text message, mobile application, face-to-face), the number of follow-up (the number of out-patient follow-up, the number of telephone follow-up, and the number of follow-up within 5 years).ResultsA total of 6 437 data items were analyzed for colorectal cancer adjuvant follow-up. ① The follow-up period of five years (2004–2015) was 56.6% (3 642/6 437), and the follow-up time was 0–201, 67 (26, 97) months. ② The highest data composition ratio of survival outcomes was “Survival” (79.7%, 4 611/5 787), and in the data with five-year follow-up period (2004–2015), the highest data composition ratio of survival outcomes was “Survival” (75.0%, 2 550/3 401), and the survival rate of the five-year follow-up period in 2008 was the highest (91.4%, 235/257). ③ The highest data composition ratio of the coping styles was the doctors’ active follow-up (76.8%, 2 121/2 762). ④ The highest data composition ratio of the follow-up path was out-patient service (90.6%, 4 236/4 676). ⑤ The highest data composition ratio of the number of out-patient follow-up was conducted by the original surgical team (100%, 4 380/4 380), the specific number was 0–130、5 (2, 10) times. The data composition ratio of telephone follow-up was 86.9% (3 808/4 380) and the specific number was 0–68、0 (0, 1) times. The highest frequency of follow-up was in the first year (89.9%, 3 044/3 386) and the specific number was 0–73、5 (3, 9) times.ConclusionBy expounding the characteristics of the colorectal cancer follow-up from colorectal cancer in DACCA, it provides some references for using big data to determine prognosis.

ObjectiveTo explore the expression of collagen Ⅳ in breast cancer and its clinical significance. We analyzed the correlation of the results with other prognostic parameters which included tumor size, status of estrogen receptor, axillary nodal status, TNM grade, and 5 years survival. The expression of collagen Ⅳ in 93 cases of human primary breast cancer as well as 5 cases of benign breast masses were examined.MethodsUsing monoclonal antibodies of collagen Ⅳ, the expression of collagen Ⅳ in breast masses were detected with immunohistochemical technique (LSAB).ResultsThe absent expression of collagen Ⅳ in the tumor masses was correlated with axillary lymph node involvement, tumor size and poor prognosis (5 years survival). The patients who had no expression of collagen Ⅳ in tumor masses had a shorter survival. ConclusionThe expression of collagen Ⅳ in tumor samples are correlated with axillary node involvement and prognosis. Collagen Ⅳ would be helpful for evaluation of invasion and treatment in breast carcinoma.

ObjectiveTo summarize research progress of comprehensive treatment based on gene therapy, immunotherapy, and targeted therapy in recent years in order to improve understanding and treatment level of triple negative breast cancer (TNBC).MethodThe literatures about TNBC treatment in recent 5 years were reviewed and summarized.ResultsTNBC was more invasive than other types of breast cancer due to its lack of targeted receptors, and its recurrence and metastasis were earlier. The treatment plan was still mainly surgical treatment, supplemented by the chemotherapy and radiotherapy.ConclusionsAlthough recent studies of TNBC in surgical treatment, chemoradiotherapy, targeted therapy and other aspects have shown a good clinical application prospect, more evidences of clinical trials with large samples are still needed. With the deepening of molecular mechanism research, endocrine therapy and targeted drug therapy, including androgen-receptor-positive, have provided some new ideas for treatment of TNBC.
In November 2022, the International Liaison Committee on Resuscitation updated the International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science with Treatment Recommendations for the sixth time. The 2022 review includes 21 topics addressed with systematic reviews by the Recovery Task Force of International Liaison Committee on Resuscitation. Among them, there are nine topics related to life support for newborns and children, including public-access defibrillation devices for children, pediatric early warning systems, maintaining normal temperature immediately after birth, suctioning of amniotic fluid at birth, tactile stimulation for resuscitation immediately after birth, use of continuous positive airway pressure for respiratory distress at term birth, respiratory monitoring in the delivery room, heart rate monitoring in the delivery room, and supraglottic airway use in neonates. The Task Force made treatment recommendations for each of the above topics after weighing evidence and discussion. In some cases, good practice statements have been provided for topics thought to be of particular interest to the resuscitation community when the evidence is insufficient to support a recommendation. Good practice statements are not recommendations but represent expert opinion. In order to facilitate the readers to understand the treatment recommendation well, in the recommendation basis part, the basic principle is briefly described. In addition, the existing problems and future research directions of each topic after the systematic reviews are also clearly stated.
Objective To explore anesthetic quality of epidural anesthesia with general anesthesia applied for surgery of rectal cancer. Methods One hundred and seventy-eight patients who were diagnosed as rectal cancer and received operation in the Central Hospital of Bazhong City from June 2010 to June 2012 were included retrospectively. These patients were divided into two groups according to the type of anesthesia， and the patients who received general anesthesia only were defined as group A， the patients who received epidural anesthesia with general anesthesia were defined as group B. The anesthetic quality and anesthetic adverse reaction were observed in two groups. Results The differences of baseline characteristics in two groups were not significant （P＞0.05）. The difference of anesthetic quality in two groups was not significant （P＞0.05）. In terms of anesthetic adverse reaction， the incidence rate of hypertension， hypotension，tachycardia， or postoperative nausea and vomiting of the group B was significantly lower than those of the group A （P＜0.05）. The incidence rate of bradycardia， premature ventricular contractions， or time of gastrointestinal function recovery had no significant differences （P＞0.05）. There was no nerve dysfunction of lower limb in two groups. Conclusion Epidural anesthesia with general anesthesia applied for surgery of rectal cancer as compared with general anesthesia only not only has the same anesthetic quality， but also has obvious advantages in decreasing anesthetic adverse reaction.
