Aim To investigate the effects of daidzeinDD on the proliferation and apoptosis of non-small cell lung cancer cells,with a focus on the possible role of the p53 signaling pathway in this regard. Methods CCK-8 method and flow cytometry were used to detect the effects of soy isoflavone crude extract and DD on the viability and apoptosis of HELF and H1299 cells. Gene microarray was used to detect the changes in gene expression after treatment of H1299 cells with DD. GSEA and differential analysis were used to screen the major pathways and key genes. RT-qPCR and Western blot were performed to verify the differences in mRNA and protein expression of key genesp53 and CASP9 in the major pathways. After p53 inhibitor Pifithrin-α inhibited the expression of p53,the effect of DD on p53 mRNA and protein expression levels was examined,and the proliferative effect on H1299 cells was observed. Results Soy isoflavone crude extract and DD promoted proliferation and inhibited apoptosis of normal lung cells and inhibited proliferation and promoted apoptosis of lung cancer cells. p53 signaling pathway was significantly enriched in the DD-treated groupNES=1.78,P=0.000,and the expressions of p53 and CASP9 genes were found to be significantly up-regulated in the treated group. Compared with the control group,mRNA expression of CASP9 and p53 significantly increased in both HELF and H1299 cells treated with DDP<0.05,and p53 protein expression also increased in HELF cellsP<0.05. After inhibition of p53 expression,DD significantly increased the mRNA expression of p53 in H1299 and HELF cellsP<0.05 and also markedly increased the expression of p53 protein in H1299 cellsP<0.05,and it was observed that DD inhibited the proliferation of lung cancer cells. Conclusions DD inhibits the proliferation and promotes the apoptosis of lung cancer H1299 cells,and the mechanism mainly involves the p53 signaling pathway.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

This study aims to explore the relationship of DNA methylation with the contents of the index components as well as the growth and development of Pogostemon cablin. The demethylation reagent 5-azacytidine(5-azaC) was used to treat the tissue culture seedlings of patchouliol-type P. cablin. High performance liquid chromatography was employed to evaluate the changes of DNA methy-lation in P. cablin, and GC-MS to detect the contents of index components in P.cablin. The agronomic characters of P.cablin were measured using the common methods. The results showcased that DNA methylation of P.cablin was significantly reduced by 5-azaC in a concentration-dependent manner. Thirty days after treatment with 5-azaC at different concentrations, the content of patchouli alcohol changed slightly; compared with that in the control group, the content of pogostone in 50 μmol·L~(-1) and 100 μmol·L~(-1) 5-azaC groups was significantly up-regulated. The 100 μmol·L~(-1) 5-azaC group had the largest differences in contents of pogostone and patchouli alcohol compared with the control group, followed by the 50 μmol·L~(-1) 5-azaC group. Ninety days after disinhibition, the content of pogostone in the treatment group was significantly increased and the content of patchouli alcohol was significantly decreased. In addition, 5-azaC significantly inhibited the growth and development of P.cablin in a dose-dependent manner. These results indicate that DNA methylation regulates the biosynthesis of the index components in patchouliol-type P.cablin and proper demethylation can directly promote the synthesis of pogostone and indirectly affect the accumulation of patchouli alcohol.

OBJECTIVE: To investigate the incidence rate and risk factors for metabolic bone disease of prematurity (MBDP) in very low birth weight/extremely low birth weight (VLBW/ELBW) infants. METHODS: The medical data of 61 786 neonates from multiple centers of China between September 1, 2013 and August 31, 2016 were retrospectively investigated, including 504 VLBW/ELBW preterm infants who met the inclusion criteria. Among the 504 infants, 108 infants diagnosed with MBDP were enrolled as the MBDP group and the remaining 396 infants were enrolled as the non-MBDP group. The two groups were compared in terms of general information of mothers and preterm infants, major diseases during hospitalization, nutritional support strategies, and other treatment conditions. The multivariate logistic regression analysis was used to investigate the risk factors for MBDP. RESULTS: The incidence rate of MBDP was 19.4% (88/452) in VLBW preterm infants and 38.5% (20/52) in ELBW preterm infants. The incidence rate of MBDP was 21.7% in preterm infants with a gestational age of < 32 weeks and 45.5% in those with a gestational age of < 28 weeks. The univariate analysis showed that compared with the non-MBDP group, the MBDP group had significantly lower gestational age and birth weight, a significantly longer length of hospital stay, and a significantly higher incidence rate of extrauterine growth retardation ( CONCLUSIONS A lower gestational age, hypocalcemia, extrauterine growth retardation at discharge, and neonatal sepsis may be associated an increased risk of MBDP in VLBW/ELBW preterm infants. It is necessary to strengthen perinatal healthcare, avoid premature delivery, improve the awareness of the prevention and treatment of MBDP among neonatal pediatricians, and adopt positive and reasonable nutrition strategies and comprehensive management measures for preterm infants.

OBJECTIVE： To explore the management model of smart pharmacy under the background of “Internet+TCM”， and to promote the improvement of the work and service quality of smart pharmacy. METHODS： The information platform and internal organization of smart pharmacy in our hospital were combined； the supervision and management of smart pharmacy and the establishment of quality control system in smart pharmacy were summarized and the development and supervision effectiveness of smart pharmacy in our hospital were evaluated. RESULTS： Our hospital established the information platform on the basis of the “Internet+TCM”. Hospital information setting were divided into online and offline. The prescriptions that were not suitable for online handling decoction and distribution service were clearly defined and the system locking settings were set up to realize effective information transmission from hospital to smart pharmacy. The service platform of smart pharmacy were set up including electronic prescription circulation system， whole-course prescription barcode recognition management system， electronic prescription audit and dispensing system， intelligent decoction control management system， smart pharmacy distribution management system， etc. It had realized seamless connection of information between smart pharmacy and patients. The internal organization included six departments： prescription audit center， dispensing center， decoction center， individualized preparation production center， logistics center and customer service center. Our hospital conducted daily supervision and management of the entire work process of the smart pharmacy from aspect of hospital management and pharmacy management. The internal service quality of smart pharmacy could be controlled by quality control system of prescription reviewing center， dispensing center， decocting center， individualized preparation center， logistics center and customer service center and pharmaceutical personnel training mechanism in smart pharmacy. Since the start of the smart pharmacy in June 2015， the number of people receiving the services of smart pharmacy had increased significantly， and the types of services and service opportunities for patients had added； the distribution service had added， and the service of individualized preparation processing and distribution had also added. Moreover， the service capacity of smart pharmacy far exceeded the demand of our hospital， and other medical institutions could share the platform of smart pharmacy. By simply counting the situation in our hospital， the average number of daily prescription increased from 387 in Jun.-Dec. of 2015 to 1 433 in 2018； the error rate showed a downward trend， among which the abnormal rate of prescription reviewing， the dispensing error rate， the decoction error rate and customer service complaints rate decreased from 2.10％， 0.13％， 0.52％， 0.13％ in Jun.-Dec. of 2015 to 0.45％， 0.05％， 0.27％， 0.04％ in 2018； total timely investment rate in logistics increased from 93.20％ in Jun.-Dec. of 2015 to 97.06％ in 2018. At present， the existing information platform， internal organization， quality control system and supervision system could ensure the orderly operation of smart pharmacy and could ensure the quality of drugs， decoction and distribution. CONCLUSIONS： However， the development of smart pharmacy in our hospital is still in its infancy. In the future， it is still necessary to strengthen the construction of information software and hardware， standardize the operation of various links， strengthen personnel training， establish an effective quality control system and explore more objective supervision mechanisms.

Objective:To observe the effect of 3 Hz and 10 Hz repetitive transcranial magnetic stimulation (rTMS) on upper limb motor function and activities of daily living in patients with ischemic stroke. Methods:From June, 2016 to September, 2017, 60 inpatients with ischemic stroke were randomly divided into sham rTMS group (n = 19), 3 Hz-rTMS group (n = 21) and 10 Hz-rTMS group (n = 20). All the patients received routine training and their own rTMS for two weeks. Their rest motor threshold (RMT) was measured, and they were assessed with modified Ashworth Scale (MAS), Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and modified Barthel Index (MBI) before and after treatment, and at six weeks follow-up. Results:There were 48 patients completing the trial, while five in 3 Hz-rTMS group, five in 10 Hz-rTMS group and two in the sham rTMS group dropped. The RMT increased in 3 Hz and 10 Hz rTMS groups (t > 2.390, P < 0.05) after treatment, but there was no significantly difference among the three groups (F = 0.164, P > 0.05). The MAS scores of elbow and wrist decreased gradually over time in 3 Hz and 10 Hz rTMS groups (P < 0.05), and the MAS scores of elbow was less in 3 Hz and 10 Hz rTMS groups than in the sham rTMS group at follow-up (P < 0.05). The interaction of time and group was significant on the FMA-UE scores (F = 14.243, P < 0.001), and the FMA-UE scores improved more in 3 Hz and 10 Hz rTMS groups than in the sham rTMS group at different stages (P < 0.01). The interaction of time and group was not significant in MBI score (F = 1.481, P > 0.05), and there was no significant difference among the three groups at any time (F < 2.925, P > 0.05). Conclusion:Both 3 Hz and 10 Hz rTMS can promote the recovery of upper limb motor function in ischemic stroke patients safely and effectively, and 10 Hz rTMS is recommended as less time is needed.
