BACKGROUND:Titanium mesh has good clinical effect in repairing skul defects, but due to the lack of bone induction ability, the titanium mesh has a poor integration with the bone tissue. OBJECTIVE:To observe the biological properties of the gradient bioactive coating materials on the titanium surface in the skul repair. METHODS: Osteoblasts were co-cultured with the titanium mesh with or without gradient bioactive coatings for 14 days, and then cel proliferation was detected using MTT method. Seventy-one patients with skul defects were enroled, including 43 males and 28 females, aged 15-60 years, and were subjected to skul repair using the titanium mesh with (observation group, n=3) or without (control group, n=38) gradient bioactive coatings. During the postoperative folow-up of 12 months, the repairing effects and adverse reactions were observed in the two groups. RESULTS AND CONCLUSION:(1)In vitrocel culture: the cel proliferative ability was increased significantly in the observation group as compared with the control group at 8, 10, 12 and 14 days after cel culture. (2)In vivo repair: the hospital stay and wound healing time in the observation group were significantly lower than those in the control group (P< 0.05), and at the final folow-up, the postoperative recovery effect was significantly higher in the observation group than the control group (P < 0.05). The titanium meshes were fixed firmly in the two groups, with no floating, infection and exposure. These results show that the titanium mesh with gradient bioactive coating has good biocompatibility and osteoinduction capacity.

The influencing factors of three themes were summarized, including social demography factors such as age, marital status and education level, the characteristic factors of bladder cancer such as the time after diagnosis and disease stage, personal financial factors such as the patient's insurance type and occupational status.Conclusions:It is necessary to standardize the use of financial toxicity measurement methods and tools for bladder cancer patients, and further explore the controversial factors affecting the financial toxicity of bladder cancer patients. Individual intervention measures should be carried out for bladder cancer patients according to the influencing factors to provide support for bladder cancer patients to control the occurrence of financial toxicity.

To discuss the potential role of medicinal herbs, especially those with effect of strengthening Qi, in the treatment of chronic heart failure (CHF) via modulating myocardial substrate metabolism. The relationships among heart failure, myocardial energetic metabolism and herbal medicine were analyzed in detail through reviewing and summarizing the accumulating knowledge and recent findings on myocardial metabolism, heart failure and herbal medicine. Either energy lack or abnormal energetic metabolism is one of the main causes to the initiation and development of heart failure. Recent studies suggest that the cardiac function in the patients with CHF could be improved by inhibiting the energy production from metabolism of fatty acid and enhancing the energy production from glucose metabolism. The concept of Qi in Chinese medicine is very close to the energy in western medicine. The decoction of Chinese medicine containing herbal medicine with effect of strengthening Qi and the herbal medicine themselves and their components were evidenced to be effective in improvement of heart failure and regulation of both lipid and glucose metabolism; more importantly, all these herbal medicine contain the multi-sugar which can be metabolized into single unit of sugar which may be metabolized as a substrate by myocardium and potentially produce the cardioprotective effect. Therefore, we may find out a novel way to explain why the herbal medicine with effect of strengthening Qi can improve cardiac function in patients with CHF. In other words, regulating myocardial metabolism is one of the mechanisms underlying the cardioprotection produced by herbal medicine with effect of strengthening Qi in the treatment of heart failure.

Objective:To explore the clinical application value and accuracy of cell-free fetal DNA (cff-DNA) technique in prenatal screening.Methods:The results of quantitative fluorescent PCR (QF-PCR) and karyotype of amniotic fluid cells were analyzed retrospectively in 2 398 monocyesis pregnant women who had been amniocentesis at the First Affiliated Hospital of Zhengzhou University from May 2013 to December 2019, and the results of 359 cases who had been examined by single-nucleotide polymorphism array (SNP array).Results:Cff-DNA test of 2, 398 cases indicated 987 cases of trisomy 21, 351 cases of trisomy 18, 135 cases of trisomy 13, 566 cases of sex chromosome abnormality, and 359 cases of other chromosome abnormality. Chromosome karyotype analysis detected 826 cases of trisomy 21, 213 cases of trisomy 18, 17 cases of trisomy 13, 221 cases of sex chromosome abnormality, and 26 cases of other chromosome abnormality. The detection rate were 83.69% (826/987), 60.68% (213/351), 12.59% (17/135), 39.04% (221/566) and 7.24% (26/359), respectively. QF-PCR detected 1 046 cases of trisomy and 188 cases of sex chromosomes abnormality, and the detection rate was 99.05% (1 046/1 056) and 85.07% (188/221), respectively. Compared with the abnormal number detected by chromosome karyotype analysis, 10 cases of trisomeric chimerism and 24 cases of sex chromosome were missed by QF-PCR. Among the 359 other chromosomal abnormalities detected by SNP array, 64 cases were consistent with the results of cff-DNA, and the detection rate was 17.83% (64/359), which was 10.59% higher than the karyotype result.Conclusions:Karyotype analysis is the gold standard for diagnosing chromosomal abnormalities. QF-PCR could diagnose common chromosome aneuploidy rapidly and accurately, and it could be used as an auxiliary detection technique for karyotype analysis. The incidence of sex chromosome chimerism is high, so missed diagnosis should be warned. SNP array could be given priority to verify chromosome microdeletion or microduplication detected by cff-DNA.
