Lung cancer is ranked the first among all malignant neoplastic diseases because of its high morbidity and mortality rate. Thus, lung cancer seriously threatens human health. More than 80%of lung cancer cases are non-small cell lung cancer (NSCLC). Unfortunately, the majority of NSCLC patients are already at the terminal stage of the disease when they seek medical attention. Such patients miss the optimal opportunity of surgery;thus, medical treatment becomes the main choice for them. Recently, molecular-target-ed therapy has made tremendous progress in clinical practice and provides a new potential treatment for patients at the terminal stage. In this review, the authors introduced some molecular-targeted therapeutic drugs to provide benefits for the individualized treatment of patients.

Breast cancer is one of the most common cancers in China. With increasing of the incidence and mortality, the harm to women is becoming much serious. Estrogen positive patients need to take 5-10 years′ endocrine drugs to prolong survival and prevent recurrence. Endocrine therapy has become one of the most common and effective methods in the treatment of breast cancer. In order to achieve the desired effect of cancer treatment, reduce cancer metastasis and recurrence rate, good compliance is essential. In conclusion, this review summarizes the evaluation of compliance, various evaluation tools and their use.

Objective To systematically evaluate the risk of primary lung cancer in breast cancer patients. Methods A computer-based search was conducted for the English literatures about the risk of primary lung cancer in breast cancer patients in Medline, Scopus and Embase databases. Two researchers independently screened the literatures, extracted the data and assessed the risk of bias. The statistical analysis was performed using the Stata 15.5 software. Results A total of 7 references were included, and the overall risk of primary lung cancer in female breast cancer patients was slightly higher than that in the general population (SIR: 1.18, 95%CI: 1.09-1.27). Subgroup analysis showed that the risk of lung cancer was significantly increased in women aged < 50 years after diagnosis of breast cancer (SIR: 1.99, 95%CI: 1.48-2.69). Conclusion Compared with the general population, the risk of primary lung cancer is increased in female breast cancer patients, especially in young women with breast cancer.

BACKGROUND: In the treatment of osteoporotic vertebral compression fractures with percutaneous vertebroplasty, the efficacy and safety of bone cement injection by unipedicular and bipedicular approaches are still controversial. Some studies suggest that bone cement injection via unipedicular approach can shorten operation time and reduce postoperative complications, while the other studies suggest that bone cement injection via bipedicular approach can make bone cement distribute more evenly in the vertebral body and relieve pain better. OBJECTIVE: To systematically assess the efficacy and safety of percutaneous vertebroplasty via unipedicular versus bipedicular approach in the treatment of osteoporotic vertebral compression fractures. METHODS: Randomized controlled trials about unipedicular versus bipedicular percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fracture published before September 18 t h, 2018 were retrieved in the PubMed, Cochrane library, Embase, CNKI, VIP, WanFang data and CBM. Two researchers independently screened all the literatures, carried out data extraction and used improved Jadad to evaluate the methodological quality of the included studies. Meta-analysis using Revam 5.3 was conducted. Egger's test was utilized to evaluate the publication bias. RESULTS AND CONCLUSION: Totally 14 randomized controlled trials including 900 cases were eventually included, 452 cases in unipedicular approach group and 448 cases in bipedicular approach group. The Meta-analysis results showed that compared with the bipedicular approach, the unipedicular approach required shorter operation time [weighted mean difference (WMD) =-16.59, 95％ confidence interval (CI) (-19.25, -13.94), P < 0.001], smaller amount of bone cement injected [WMD=-1.27, 95％ CI (-1.64, -0.89), P < 0.001], and had lower incidence of cement leakage [relative risk=0.70, 95％ CI (0.53, 0.92), P =0.01]. There were no significant differences in short-and long-term Visual Analogue Scale scores, short-and long-term Oswestry Disability Index scores, and the postoperative incidence of adjacent vertebral fractures between the two groups (P> 0.05). Overall, bone cement injection both via bipedicular and unipedicular approaches can lead to a significant improvement in pain relief and living quality of osteoporotic vertebral compression fracture patients, but bone cement injection via unipedicular approach can shorten operation time, reduce cement volume and lower the incidence of cement leakage compared with the bipedicular approach.

OBJECTIVE: To investigate the effect of environmental estrogen bisphenol A (BPA) exposure on apoptosis of mouse ovarian preantral follicular granulosa cells and ovarian development and explore the underlying mechanism. METHODS: Mouse ovarian preantral follicular granulosa cells were isolated from female ICR mice at postnatal day (PND) 10 and cultured RESULTS: Compared with the control cells group, the isolated cells exposed to a low concentration of BPA (50 μmol/L) showed a significantly lowered apoptosis rate, increased mitochondrial membrane potential, and enhanced cellular proliferation ( CONCLUSIONS BPA can concentration-dependently regulate the function of ovarian preantral follicular granulosa cells in mice and potentially affects both the pregnant mice and the offspring female mice in light of early ovarian development.

The oral microbiota is associated with oral diseases and digestive systemic diseases. Nevertheless, the causal relationship between them has not been completely elucidated, and colonisation of the gut by oral bacteria is not clear due to the limitations of existing research models. The aim of this study was to develop a human oral microbiota-associated (HOMA) mouse model and to investigate the ecological invasion into the gut. By transplanting human saliva into germ-free (GF) mice, a HOMA mouse model was first constructed. 16S rRNA gene sequencing was used to reveal the biogeography of oral bacteria along the cephalocaudal axis of the digestive tract. In the HOMA mice, 84.78% of the detected genus-level taxa were specific to the donor. Principal component analysis (PCA) revealed that the donor oral microbiota clustered with those of the HOMA mice and were distinct from those of specific pathogen-free (SPF) mice. In HOMA mice, OTU counts decreased from the stomach and small intestine to the distal gut. The distal gut was dominated by Streptococcus, Veillonella, Haemophilus, Fusobacterium, Trichococcus and Actinomyces. HOMA mice and human microbiota-associated (HMA) mice along with the GF mice were then cohoused. Microbial communities of cohoused mice clustered together and were significantly separated from those of HOMA mice and HMA mice. The Source Tracker analysis and network analysis revealed more significant ecological invasion from oral bacteria in the small intestines, compared to the distal gut, of cohoused mice. In conclusion, a HOMA mouse model was successfully established. By overcoming the physical and microbial barrier, oral bacteria colonised the gut and profiled the gut microbiota, especially in the small intestine.

Urea transporters (UT) play a vital role in the mechanism of urine concentration and are recognized as novel targets for the development of salt-sparing diuretics. Thus, UT inhibitors are promising for development as novel diuretics. In the present study, a novel UT inhibitor with a diarylamide scaffold was discovered by high-throughput screening. Optimization of the inhibitor led to the identification of a promising preclinical candidate,
