Objective To explore the effect of management model of clinical pharmacists participating in multidisciplinary collaborative diagnosis and treatment(MDT)for new anti-tumor drugs in the national medical insurance drug negotiation(hereinafter referred to as"national negotiation"),including efficacy,safe-ty,economy and rationality.Methods The medical records of 326 cases using novel anti-tumor drugs by na-tional negotiation and conforming to the including and excluding standards in this hospital from July 2018 to June 2023 were retrospectively analyzed.The patients were divided into the MDT group(n=122)and non-MDT group(n=204).The patients diagnosed as non-small cell lung cancer(NSCLC)in the two groups were extracted and defined as the MDT-NSCLC subgroup(n=41)and non-MDT-NSCLC subgroup(n=77).The progression-free survival(PFS),overall survival(OS),disease control rate(DCR)and the indexes such as survival quality and medical quality control were compared between the groups.Results The median PFS in the two groups was 12.7 months and 8.0 months,the median OS was 75.2 months and 56.3 months,DCR was 96.72％and 81.86％respectively,and the differences were statistically significant(P＜0.05).The COX multivariate regression analysis indicated that the HR value of clinical pharmacists participating in MDT was higher than the other influencing factors.The median PFS time in the MDT-NSCLC subgroup and non-MDT-NSCLC subgroup was 10.5 months and 6.7 months,DCR was 97.30％and 75.64％respectively,and the differences were statistically significant(P＜0.05),the median OS time was 55.1 months and 40.3 months respectively,and the difference was statistically significant(P＞0.05).The COX multivariate regression anal-ysis indicated that the HR value with clinical pharmacists participating in MDT was higher than the other in-fluencing factors;The adverse reaction occurrence rate in the MDT group and non-MDT group was 45.9％and 58.3％respectively,and the difference was statistically significant(P＜0.05).The KPS score after treatment in the MDT group was higher than that in the non-MDT group,and the difference was statistically significant;in the aspect of medical quality control,the average drug proportion in the MDT group and non-MDT group was 63.93％and 64.54％respectively,the rational drug rate of comments on prescription was 98.36％and 88.73％respectively,the patient satisfaction average value was 90.69 points and 87.36 points respectively and the differences were statistically significant(P＜0.05).Conclusion Clinical pharmacists participating in MDT related to novel anti-tumor drugs by national negotiation is beneficial to improve the therapeutic effects,living quality and patient satisfaction,also benefit to management and control of off-label drug use and medical quality control indexes.

To investigate the current situation and demand for specialized development of allergy nursing in 88 hospitals in Guangdong Province, as well as to provide evidence for the management of allergy nursing. From August to December 2023, a cross-sectional study was conducted to analyze the core managers of allergy nursing-related work in eighty-eight hospitals in Guangdong Province supported by the Allergy Nursing Branch of the Guangdong Nurses Association and the Nursing Group of the Allergy Branch of the Guangdong Medical Association. An online survey was conducted using the Delphi method to compile a questionnaire on the current status and demand for specialized development of allergy nursing in Guangdong Province. Chi-square tests and Fisher′s exact probability method were used to analyze the differences in the current status of specialty technology applications and the development and demand of specialized nursing between hospitals with or without allergy specialty departments. The results showed that among the eighty-eight hospitals in the nineteen prefecture-level cities surveyed in Guangdong Province, 17 hospitals (19%) had established allergy specialty departments, all of which were top-tier tertiary hospitals. The establishment duration [ M ( Q1, Q3)] was 3 (1, 10) years. The implementation rates of skin prick test (94%, 16/17), in-vitro examination (82%, 14/17), nasal endoscopy (82%, 14/17), subcutaneous specific immunotherapy (82%, 14/17), multidisciplinary consultation (65%, 11/17), fractional exhaled nitric oxide detection (47%, 8/17), skin patch test (41%, 7/17), and autologous serum skin test (35%, 6/17) in hospitals with allergy department were higher than those in hospitals without allergy department [59%, 42/71 ( χ 2= 7.462, P=0.006)], [54%, 38/71 ( χ 2= 4.717, P=0.030)], [51%, 36/71 ( χ 2= 5.599, P=0.018)], [34%, 24/71 ( χ 2= 13.177, P<0.001)], [24%, 17/71 ( χ 2= 10.505, P=0.001)], [24%, 17/71 ( χ 2= 5.540, P=0.019)], [11%, 8/71 (Fisher′s exact test, P=0.008)], [11%, 8/71 (Fisher′s exact test, P=0.025)]. In the development plan of allergy nursing in the next two years, hospitals that had set up allergy departments had a higher proportion in adding nurses (82%, 14/17, χ 2= 13.177, P<0.001), formulating specialized nurse training plans (71%, 12/17, χ 2= 3.980, P=0.046), formulating group standards or clinical guidelines (41%, 7/17, Fisher′s exact test, P=0.046), and formulating assessment standards (53%, 9/17, Fisher′s exact test, P=0.002). The demand for all aspects of allergy specialty nursing knowledge and skills accounted for more than 50%, and it was not related to whether the hospital set up an allergy department. In conclusion, the specialized development of allergy nursing in Guangdong province is still in its early stages, and there is a great demand for improving knowledge and skills in allergy. Further standardization of specialty construction is needed, along with the training of allergic nurses, to promote the comprehensive development of allergic reaction nursing specialties from point to area.

Objective:To summarize treatment strategies and outcomes of patient suffer from acute Stanford type A aortic dissection(ATAAD) with mesenteric malperfusion.Methods:We collected 13 patients with mesenteric malperfusion among 321 ATAAD patients underwent surgery at Nanjing First Hospital during January 2019 to September 2022. Characteristics of these patients were recorded. We analyzed their early and late clinical outcomes.Results:Two patients underwent revascularization-first strategy in hybrid operation room had no in-hospital mortality or complication related to mesenteric ischemia. There were 11 patients with central repair-first strategy. Eight patients appeared mesenteric complications and 2 of them needed extra gastrointestinal surgery. Six in-hospital mortality were recorded in central repair-first patients.Conclusion:We recommended revascularization-first strategy with followed central repair in hybrid operation room for patients suffered from ATAAD with mesenteric malperfusion. Those who underwent central repair-first strategy because of coronary artery or cerebral malperfusion and unstable hemodynamic needed percutaneous angiography of mesenteric artery.

Objective:To evaluate the detection ability and efficiency of single nucleotide polymorphisms array (SNP-array) and next generation sequencing (NGS) in preimplantation genetic testing (PGT).Methods:Totally 188 couples who carried pathogenic gene mutation and requested preimplantation genetic testing for monogenic (PGT-M) treatment were retrospectively analyzed in the Reproductive Center of Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region during January 2020 and August 2022. After ovulation induction, insemination was conducted by intracytoplasmic sperm injection (ICSI) and cultured in vitro, 995 blastocysts were harvested and biopsied. After whole genome amplification (WGA) of the genetic material from embryonic cell samples, their carrying status of mutations and chromosome copy number variations (CNVs) were analyzed by SNP-array or NGS, respectively, and along with mutation direct detection by Sanger sequencing or Gap-PCR. The relationship between female age and the number of blastocysts was analyzed, as well as the proportion of embryos carrying mutations and pathogenic CNVs. The detection success rate and accuracy of different molecular diagnostic techniques used in PGT were compared. Amniocentesis prenatal diagnosis was performed in the second trimester after successful intrauterine transfer of embryos. Results:1) A total of 924 embryo samples were successfully performed genetic testing, with a total success rate of 92.9%, and 389 embryos (42.1%) can be transferred according to these results. 2) In detecting deletional α-thalassemia, the success rate of Gap-PCR [84.9% (465/548)] was lower than that of SNP-array [98.7% (81/82)] and NGS [92.5% (431/466)]. However, the success rate of direct mutation detection by Sanger sequencing [98.5% (440/447)] was not significantly different from that by SNP-array [95.6% (110/115)] and NGS [96.1% (319/332)]. There were 38 embryo samples with direct mutation detection results inconsistent with those based on SNP haplotyping. In addition, 4 embryo samples failed SNP haplotyping due to chromosomal recombination. 3) Compared with NGS, SNP-array had a lower success rate [83.7% (165/197)] in detecting CNVs, but it could find out more types of chromosomal abnormalities. 4) A total of 152 embryo transfers were performed, 107 patients got clinical pregnancies, 69 patients completed amniocentesis prenatal diagnosis, and 42 healthy infants were delivered.Conclusion:In considering the detection efficiency, SNP-array is suitable for analyzing embryos which carry multiple pathogenic genes, rare monogenic or deletion mutations, whereas NGS is suitable for detecting common types of mutations. Meanwhile, using Sanger sequencing and Gap-PCR to directly detect the mutations can improve the success rate and accuracy of PGT. Our findings would provide a basis for PGT technicians to select appropriate detection platforms based on the type of mutations and the situation of patients.

Objective: To investigate the mental health status of female migrant workers in a city. Methods: From August to December, 2016, cluster random sampling was used to select female migrant workers aged 16-60 years from 10 districts of this city, and Symptom Checklist-90 (SCL-90) and a questionnaire on general status were used. Results: Among these female migrant workers, the detection rates of obsessive-compulsion, hostility, and depression were 6.62%, 4.18%, and 4.10%, respectively. There was a significant difference in the detection rate of mental health issues between the female migrant workers from different districts, with different occupations, or with different education levels (P<0.05) . Districts, occupation, and education level were associated with mental health issues, after adjustment for age (P<0.05) . Conclusion Although female migrant workers in this city have a high mental health level, the issues such as obsessive-compulsion, hostility, and depression should be taken seriously. Targeted mental health surveys and comprehensive interventions should be implemented to improve the mental health level of female migrant workers.

Objective: To study status of social support and its influencing factors in female migrant workers. Methods: Study participants were selected with a random cluster design from participants 16-60 years old in non-registered residents from 10 districts in one city. Social support revalued scale and general questionnaire were used to survey social support status of female migrant workers in August-December of 2016. Results: There was statistic difference in social support among different districts, occupations, and income of female migrant workers (P<0.05) . Results of multiple linear regression demonstrates that districts, occupations, and income of female migrant workers were associated with social support scale (district standarized β=0.03, occupations standarized β=-0.03, incorue standarized β=0.10, P<0.05) . Conclusion We should be attentive to self-employed and Low-income participants among female migrant workers.

Objective To investigate the molecular epidemiological characteristics and homology of Staphylococcus aureus (S. aureus)isolated from patients in intensive care units (ICUs)of a hospital,so as to provide laboratory basis for the effective control of healthcare-associated infection(HAI). Methods 62 S. aureus strains isolated from various specimens from ICU patients with infection in March-August 2013 were collected,7 housekeeping genes were amplified with polymerase chain reaction (PCR),the amplified products were sequenced,ST typing of strains was performed by multilocus sequence typing (MLST ), phylogenetic analysis of ST typing was conducted. Results 62S. aureus strains were amplified specific product of 7 housekeeping genes;there were 10 ST genotypes, in which 2 ST genotypes(STn1and STn2)were first discovered,1 ST genotype(ST675)was first discovered domes-tically. ST239 was the main ST type of S. aureus from ICU patients in this hospital,accounting for 74.20% ,which distributed in 6 ICUs,ST5 distributed in 3 ICUs. 62 strains formed 7 main branches in the phylogenetic tree,55 (88.71% )MRSA strains were detected. Conclusion S. aureus isolated from hospital ICUs has some homology, and the small number of types showed the trend of concentrated distribution.

Objective To investigate the effects of Mycobacterium tuberculosis heparin-binding he-magglutinin (HBHA) on the polarization of mouse bone marrow-derived macrophages (BMDM) and a mu-rine macrophage cell line(Raw264.7 cells). Methods After HBHA was confirmed to be able to enter into macrophages by immunofluorescence, mouse BMDM and Raw264. 7 cells were treated with LPS (100 ng/ml)+IFN-γ (2.5 ng/ml),IL-4 (20 ng/ml),HBHA (1 μg/ml,3 μg/ml,6 μg/ml,10 μg/ml) and ESAT-6 (5 μg/ml),respectively. IL-6,IL-12 and TNF-α in the supernatants of cell culture were measured by ELISA. RT-PCR was performed to detect the expression of molecular markers of macrophage polarization [inducible nitric oxide synthase (iNOS), TNF-α, Arg-1 and CD206] at mRNA level. Western blot assay was used to detect the expression of iNOS and Arg-1 at protein level. Results Increased secretion of IL-6, IL-12 and TNF-α in the supernatants of cell culture and enhanced expression of iNOS and TNF-α at mRNA level were observed after treating BMDM with Mycobacterium tuberculosis HBHA. Similarly,in HBHA-trea-ted Raw264.7 cells,the secretion of IL-6 and the expression of TNF-α were also up-regulated. Mycobacteri-um tuberculosis HBHA and ESAT-6 had similar effects on murine macrophages. Neither of them could in-crease the expression of Arg-1,a molecular marker of M2 macrophages,in BMDM at protein level,but both enhanced the expression of iNOS,a molecular marker of M1 macrophages,in BMDM and Raw264.7 cells. Conclusion Mycobacterium tuberculosis HBHA can induce the polarization of murine macrophages to M1 phenotype.
