To investigate the influence of six exogenous pathogenic factors on asthma in children and to observe the changes of microscopic indexes in cold- and heat-type asthma. Logistic regression analysis was applied to analyze the influence of six exogenous pathogenic factors and the changes of serum level of IgE, eosinophil (EOS) counting, contents of third component of complement (C3) and C-reactive protein (CRP) were observed. The exogenous factors of wind, cold, damp, wind-cold mixture and cold-damp mixture were the risky factors of asthma. Serum levels of IgE and EOS were higher in cold-type asthma and serum contents of C3 and CRP were higher in heat-type asthma (P

Objective · To prepare the liposomal pemetrexed and investigate its effects on MCF-7 breast cancer cells in vitro and nude mice bearing MCF-7 xenograft tumors. Methods · Liposomal pemetrexed was prepared by film dispersion method. Inhibition of MCF-7 breast cancer cell lines was evaluated by CCK-8 method, and anti-tumor effects were investigated on Balb/c nude mice bearing MCF-7 xenograft tumors. Results · Liposomal pemetrexed inhibited the growth of MCF-7 cells. When the concentrations of pemetrexed were 0.20, 0.40 and 10.00 μg/mL, the cell viability in experiment group (liposomal pemetrexed) was significantly lower than that in control group (pemetrexed of same concentration gradient), with P values of 0.013, 0.035 and 0.041, respectively. Compared with blank group (same volume of PBS), the volumes and weights of tumors of nude mice in experiment group(liposomal pemetrexed) and control group (same volume of pemetrexed) were significantly lower, and the volume and weight of tumor in experiment group were also significantly lower than those in control group (P=0.000). Conclusion · Compared to bulk drug of pemetrexed, liposomal pemetrexed can inhibit the growth of MCF-7 breast cancer cells and the Balb/c nude mice bearing MCF-7 xenograft tumors.

PURPOSE: Our aim is to compare 3-dimensional mesh fixation using titanium tacks combine with n-butyl cyanoacrylate glue (NBCG) (COMBINE group) versus NBCG only (NBCG group) in totally extraperitoneal inguinal hernioplasty (TEP). METHODS: This is a retrospectively study of patients diagnosed with unilateral inguinal hernia and underwent TEP with 3-dimensional configured polyester mesh fixation using titanium tacks combine NBCG or NBCG only at the University of Hong Kong-Shenzhen Hospital with data prospectively collected. Operative details and outcomes were compared including: operating time, size of defect, total hospital cost, post-operative pain scores and recurrence. RESULTS: From 08.2013 to 03.2016 a total of 219 patients were included. There was no significant difference between COMBINE group and NBCG group in mean age (52.5 years versus 48.2 years), mean size of defects (2.4 cm versus 2.6 cm), and operating time (121 mins versus 111 mins). There were significant differences between COMBINE group and NBCG group in total hospital cost (3035 USD versus 2022 USD), post-operative pain score on day 2 to day 4 (VAS: 1.4 versus 1.0, 1.0 versus 0.4, 0.5 versus 0.2). There was one recurrence in COMBINE group (p=0.276) with overall recurrence of 0.46%. CONCLUSION: Patients with inguinal hernia underwent TEP with 3-dimensional configured polyester mesh with NBCG fixation only having comparative surgical outcome to COMBINE group. A recurrence of 0.46% can be achieved with this combination. Tacks fixation may cause more post-operative pain and increase hospital cost. Use of N-butyl cyanoacrylate glue in TEP is safe and effective in our clinical series.

The pregnancy rate of young breast cancer patients is far lower than that of the general population, which is possibly related to many factors such as patients' concern about tumor recurrence, ovarian dysfunction caused by chemotherapy, long endocrine treatment cycle, lack of professional multidisciplinary cooperation team and so on. At present, there is limited data on fertility preservation before tumor treatment and successful pregnancy and delivery after treatment for young breast cancer patients. In order to successfully carry out the fertility preservation of young female breast cancer patients, strengthen their physical and mental health, promote the return of social roles and improve the health level of their offsprings, this article reviews the factors affecting fertility, the appropriate population for fertility preservation, and the impact on the prognosis of breast cancer, as well as the timing and methods of fertility preservation and recovery opportunities in young women with breast cancer.

Cancer treatments may improve the long-term survival rate of young patients with breast cancer, but also lead to a decrease in fertility. With the younger incidence of breast cancer in China, the fertility needs of this group have received more attention, and fertility preservation technology suitable for cancer patients is developing continuously. However, there are still many problems in the implementation of fertility preservation for young breast cancer patients in China. Patients and breast surgeons have insufficient understanding and conservative attitudes towards fertility preservation technology. And there is a lack of reproductive experts in the treatment process. What′s more, the long-term follow-up and information management of patients undergoing fertility preservation are defective. In response to the above, this paper discusses how to deal with patients with potential reproductive needs in clinical practice from the perspective of breast surgeons. The first is to improve their own understanding of fertility preservation, such as the progress of relevant technologies and applicable population, when to intervene, when and how to get pregnant after cancer treatment. Secondly, education for patients must be strengthened, which should include not only fertility preservation, but also scientific contraceptive methods during cancer treatment and treatment measures for unexpected pregnancy. Finally, hospitals and relevant units should standardize the multidisciplinary team of breast cancer, and strengthen the comprehensive management of young breast cancer patients, thus to provide young breast cancer patients with more scientific cancer treatment programs and more reproductive opportunities.

Colorectal cancer (CRC) is one of the leading causes of death worldwide. Thus, the development of new therapeutic targets for CRC treatment is urgently needed. SGK1 is involved in various cellular activities, and its dysregulation can result in multiple cancers. However, little is known about its roles and associated molecular mechanisms in CRC. In present study, we found that SGK1 was highly expressed in tumor tissues compared with peri-tumor samples from CRC patients. In vitro experiments revealed that SGK1 overexpression promoted colonic tumor cell proliferation and migration and inhibited cell apoptosis induced by 5-fluorouracil (5-FU), while SGK1 shRNA and inhibitors showed the inverse effects. Using CRC xenograft mice models, we demonstrated that knockdown or therapeutic inhibition of SGK1 repressed tumor cell proliferation and tumor growth. Moreover, SGK1 inhibitors increased p27 expression and promoted p27 nuclear accumulation in colorectal cancer cells, and p27 siRNAs could attenuate the repression of CRC cell proliferation induced by SGK1 inhibitors. Collectively, SGK1 promotes colorectal cancer development via regulation of CRC cell proliferation, migration and survival. Inhibition of SGK1 represents a novel strategy for the treatment of CRC.

Repair of lower abdominal incisional hernia is always a surgical challenge. TAPE technique has been described for the repair of supra-pubic midline incisional hernia with satisfactory outcome. Its indication can be extended for treatment of non-midline lower abdominal hernia. Peritoneal incision is created just below the hernia defect with pre-peritoneal dissection to expose supra-pubic preperitoneal space with Cooper's ligament exposed. Non-adhesive mesh then placed over preperitoneal space and partially intra-peritoneally, and cover the whole extra-peritoneal space prepared to ensure enough overlapping. Mesh is fixed by tackers for intra-peritoneal part, most inferior fixation points were at peritoneal incision line. Extra-peritoneal part of meshes is fixed at the safety zone and covered up by the peritoneal flap to avoid mesh migration. Fixation of the meshes at the lateral aspects were facilitated by the peritoneal flap and subsequent fibrosis and adhesion to the extra-peritoneal structures in cases of lateral lower abdominal hernia. Repair of midline and lateral lower abdominal incisional hernia with this novel modified technique with prosthetic mesh is safe and effective. A larger case series and longer follow-up is required for validation of this technique.
