OBJECTIVETo detect the effects of human interleukin-1beta (IL-1beta) and Dexamethasone (DEX) on the expression level of keratinocyte growth factor (KGF) in cultured human fibroblasts of normal oral and oral lichen planus (OLP) mucosa.

METHODSThree concentration gradients of IL-1beta and DEX were added to cultured fibroblasts of human normal oral and OLP mucosa respectively. 72 hours later, the supernatant was harvested for the detection of KGF concentration with enzyme linked immunosorbent assay (ELISA). Total RNA of the fibroblasts was extracted and reverse transcribed. The resulting cDNA was then amplified by polymerase chain reaction (PCR) to detect the KGF mRNA.

RESULTSThe results of the ELISA and PCR showed that the expression levels of KGF protein and mRNA were higher if the cells were treated with IL-1beta. However, the expression levels of KGF protein and mRNA were significantly reduced if the fibroblasts were treated with DEX.

CONCLUSIONIL-1beta can promote KGF expression levels of cultured normal oral and OLP fibroblasts, and it is concentration-dependent. While DEX can inhibit KGF expression of cultured normal oral and OLP fibroblasts, and it is also concentration-dependent.

ObjectiveTo report the results of preventive control program of severe thalassemias in Zhuhai City of Guangdong Province from 1998 to 2010.MethodsAs the guide centre of marriage and childbearing and the greatest maternity hospital in Zhuhai City of Guangdong Province,Zhuhai Municipal Maternity and Child Healthcare Hospital constructed the genetic screening network for thalassemias testing and referred for follow-up and for genetic counseling.The couples for premarital medical examination or regular healthcare examination in pregnancy were enrolled to this preventive control program.A conventional strategy of screening for heterozygote was used to identify the α- and β-thalassemia traits in women and their spouses according to the standard procedures of hematological phenotype analysis which was recommended by Thalassemia International Federation (T IF).Then those suspected couples at risk were diagnosed for α- and β-thalassemia by PCR-based DNA assays.The couples at risk for severe thalassemias were counseled and offered prenatal diagnosis and termination of pregnancy in case of an affected fetus in the rights of consent and of option voluntarily.ResultsFrom January 1998 to December 2010,85 522 brides and grooms-to-be for premarital screening and 41 503 pregnant women in addition to 14 141 partners for prenatal screening were recorded,the covering rates of premarital screening and prenatal screening in the city were 92.698％ (from 1998 to 2003) and 27.667％ (from 2004 to 2010),respectively.Totally 10 726 cases were found to be the carriers of thalassemias,with 7393 for o-thalassemia (5.237％,7 393/141 166) and 3333 for β-thalassemia (2.361％,3 333/141 166).A total of 257 couples at-risk for severe thalassemias were detected including 190 for α-thalassemia and 67 for β-thalassemia.Among them,251 (97.7％,251/257) couples were performed prenatal diagnosis.During the preventive control program,a total of 72 fetuses with severe thalassemias including hemoglobin H disease were voluntarily terminated.In Zhuhai City,the average annual birth rate of fetuses with severe thalassemia was declined by 32.9％ (49/149).ConclusionsThis study has reduced effectively birth rate of perinatal infants with severe thalassemias in Zhuhai City by genetic screening and prenatal diagnosis of thalassemia in the large population of 13 years.Our summary comes out of technical proposals for prenatal screening and diagnosis,which could be take example by preventative control of thalassemia in other regions of China where are prevalent.

Objective:To analyze effects of tectorigenin on improving cognitive deficits in rats with vascular dementia(VD)by regulating Toll-like receptor 4(TLR4)/myeloid differentiation factor 88(MyD88)/nuclear factor-κB(NF-κB)signaling pathway.Methods:A total of 72 rats were randomly divided into sham operation group,model group,low,medium and high doses[25,50,100 mg/(kg·d)]tectorigenin groups and positive control group[piracetam 324 mg/(kg·d)],with 12 rats in each group.Except for sham operation group,VD models were replicated in other groups.After successful modeling,different doses tectorigenin groups and positive control group were administered intragastrically with different doses of tectorigenin and piracetam,while other groups were administered intragastrically with same volume of normal saline for 28 d.Spatial learning and memory ability were detected by Morris water maze.Neurotransmitter levels in hippocampus interstitial fluid were detected by high performance liquid chromatography-electro-chemical.Brain-derived neurotrophic factor(BDNF)and tyrosine kinase receptor b(TrkB)expressions in hippocampus were detected by RT-qPCR and Western blot.TLR4/MyD88/NF-κB pathway-related proteins in hippocampus were detected by Western blot.Results:Compared with sham operation group,escape latency was longer,while stay time in target area and times of crossing platform were lower in model group(P<0.05).Compared with model group,escape latency was shorter,while stay time in target area and times of crossing platform were higher in medium and high doses tectorigenin groups(P<0.05).NE,DA,5-HT and 5-HIAA levels in model group were lower than those in sham operation group(P<0.05),which were higher in medium and high doses tectorigenin groups than model group(P<0.05).Compared with sham operation group,BDNF and TrkB mRNA and proteins levels were lower,while TLR4,MyD88 and p-NF-κB p65/NF-κB p65 proteins levels were higher in model group(P<0.05).Compared with model group,BDNF and TrkB mRNA and proteins levels were higher,while TLR4,MyD88 and p-NF-κB p65/NF-κB p65 proteins levels were lower in medium and high doses tectorigenin groups(P<0.05).Conclusion:Tectorigenin can improve cognitive deficits in VD rats,which may be related to regulating TLR4/MyD88/NF-κB signaling pathway.

Objective:To observe the effect of point application-invigorate the spleen and kidney, circulation of blood formula (PA) combined with five-animal exercise (FAE) on improving the nutritional status for asthenia of patients with dialysis, and provide evidence for the rehabilitation treatment of dialysis patients.Methods:According to the random number table method, a total of 80 patients treated with regular dialysis at Department of Nephrology, the Affiliated Hospital of Nanjing University of Chinese Medicine from April 2020 to December 2021 were randomly divided into experimental group and control group, with 40 cases in each group. Participants in the control group received regular dialysis, basic treatment and diet nursing (RBD). Participants in the experimental group received RBD plus PA+FAE. Labaratory test results, Subjective Global Assessment scale score and Traditional Chinese medicine symptom score were measured at baseline and 12-weeks after the intervention. The Fried Frailty scale score was measured at baseline, 4, 8, and 12 weeks after the intervention.Results:The control group aged (54.08 ± 11.34) years old, 23 males, 17 females; the experimental group aged (57.38±9.89) years old, 19 males, 21 females. After 4, 8 and 12 weeks of intervention, the Fried Frailty Scale scores of the experimental group at different time points were 2 (2, 2), 1 (1, 2) and 1 (0, 1), respectively, lower than 3 (2, 4), 2 (2, 3) and 2 (2, 3) of the control group, and the differences in time effect, inter-group effect and interaction effect were statistically significant ( F=105.76, 18.38, 46.67, all P<0.01). Further pairwise comparisons within groups indicated significant differences of Fried Frailty scale scores at different time points ( Z=-2.78, -4.01, -6.08, all P<0.01). After 12-week of intervention, the results of hemoglobin, serum albumin and serum prealbumin were (107.88 ± 15.58) g/L, (39.10 ± 4.92) g/L, and (289.36 ± 72.05) mg/L in the experimental group, respectively, higher than (100.15 ± 17.62) g/L, (36.93 ± 4.72) g/L, (255.63 ± 75.35) mg/L in the control group ( t=-2.08, -2.01, -2.05, all P<0.05). Subjective Overall Assessment scale was found a significant difference between the 2 groups ( χ2=10.91, P<0.01): the number of grade A (good nutrition) and B (mild to moderate malnutrition) were 36 and 4 in the experimental group and 23 and 17 in the control group. Traditional Chinese medicine symptom score was (4.68 ± 2.50) in the experimental group, lower than (9.58 ± 4.40) in the control group ( t=6.13, P<0.01). Conclusions:Point application-invigorate the spleen and kidney and circulation of blood formula combined with five-animal exercise can effectively improve the nutritional status of dialysis patients and reduce the weakness of patients

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
