Objective To explore the influence of Buqi Qingchang Decoction(composed of Buzhong Yiqi Decoction plus Baitouweng Decoction with Curcumae Radix and Curcumae Longae Rhizoma added)combined with XELOX chemotherapy and Bevacizumab targeted therapy on the clinical efficacy,quality of life and survival period of patients with metastatic colorectal cancer of qi deficiency and damp-heat syndrome.Methods A retrospective study was conducted in 70 patients with metastatic colorectal cancer of qi deficiency and damp-heat syndrome who were admitted to the Department of Oncology,Chongqing Hospital of the First Affiliated Hospital of Guangzhou University of Chinese Medicine(Chongqing Beibei District Hospital of Traditional Chinese Medicine)from December 2020 to December 2023.The patients were divided into an observation group and a control group according to the therapy,with 35 cases in each group.The control group was treated with XELOX chemotherapy combined with Bevacizumab targeted therapy,while the observation group was given oral administration of Buqi Qingchang Decoction together with chemotherapy and targeted therapy.The changes in the serum levels of tumor markers such as carcinoembryonic antigen(CEA)and carbohydrate antigen 199(CA199),and Karnofsky Performance Status(KPS)scores for quality of life in the two groups were observed before and after treatment.Moreover,the clinical efficacy,progression-free survival(PFS)and overall survival(OS)were compared between the two groups.Results(1)After treatment,the objective response rate(ORR)and disease control rate(DCR)in the observation group were 51.42％(18/35)and 85.71％(30/35),respectively,which were significantly higher than those in the control group[25.71％(9/35)and 54.29％(19/35),respectively],and the differences between the two groups were statistically significant(P＜0.05 or P＜0.01).(2)The PFS of the observation group was 16.7 months and that of the control group was 12.9 months,and the OS of the observation group was 23.3 months and that of the control group was 17.7 months.The PFS and OS of the observation group were significantly longer than those of the control group,and the differences were statistically significant(P＜0.05 or P＜0.01).(3)After treatment,the levels of serum CEA and CA199 in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the KPS scores were significantly increased compared with those before treatment(P＜0.05).The decrease of serum CEA and CA1 99 levels and the increase of KPS scores in the observation group were superior to those in the control group,and the differences were statistically significant(P＜0.05).Conclusion XELOX chemotherapy and Bevacizumab regimen combined with Buqi Qingchang Decoction exerts certain effect in treating metastatic colorectal cancer.The combined therapy is effective on enhancing the efficacy to a certain extent,prolonging the survival period of patients,reducing the risk of disease progression,decreasing the levels of serum tumor markers,and improving the quality of life of patients.

Objective To investigate the clinical efficacy of Shen Jiang Zhouche Powder(composed of modified Lizhong Pill,Erchen Decoction,and Zhouche Pill)in the treatment of malignant pleural effusion(MPE)patients with fluid retention in the chest and hypochondrium syndrome.Methods Eighty MPE patients with fluid retention in the chest and hypochondrium syndrome were randomly divided into the treatment group and the control group,with 40 cases in each group.Both groups were given conventional western medical treatment,and additionally the control group was treated with Spironolactone and Furosemide Tablets orally while the treatment group was treated with Shen Jiang Zhouche Powder orally.A total of 21 days constituted one course of treatment,and both groups were treated for two courses and then were followed up for one month.The changes of traditional Chinese medicine(TCM)syndrome scores,scores of Karnofsky Performance Status(KPS)established by Eastern Cooperative Oncology Group(ECOG),and scores of self-rating scale of sleep(SRSS)in the two groups were observed before and after treatment.After treatment,the clinical efficacy,TCM syndrome efficacy and clinical safety of the two groups were evaluated.Results(1)After treatment and one-month follow-up,the total clinical effective rate in the treatment group was 67.5%(27/40)and that in the control group was 45.0%(18/40),and the intergroup comparison(by chi-square test)showed that the clinical efficacy of the treatment group was significantly superior to that in the control group(P＜0.05).(2)After two courses of treatment,the total effective rate of TCM syndrome improvement in the treatment group was 92.5%(37/40)and that of the control group was 50.0%(20/40),and the intergroup comparison(by chi-square test)showed that the TCM syndrome efficacy in the treatment group was significantly superior to that in the control group(P＜0.01).(3)After treatment,except for the score of dyspnea in the control group,the scores of each of the main symptoms(including dry cough,chest tightness,chest pain,tightness of breath,dyspnea)and accompanied symptoms as well as the total TCM syndrome scores in the two groups were significantly decreased compared with those before treatment(P＜0.05 or P＜0.01),and the decrease of the scores of each of the main symptoms and accompanied symptoms as well as the total TCM syndrome scores were significantly superior to those in the control group(P＜0.05 or P＜0.01).(4)After treatment,the scores of KPS and SRSS in the two groups were significantly improved compared with those before treatment(P＜0.01),and the improvement in the treatment group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(5)There were no obvious adverse reactions occurring in both groups,while only mild symptoms of the adverse reactions were presented.The incidence of adverse reactions in the treatment group was 7.5%(3/40)and that in the control group was 12.5%(5/40),and the difference was not statistically significant between the two groups(P＞0.05).Conclusion Shen Jiang Zhouche Powder exerts certain clinical efficacy in the treatment of MPE patients with fluid retention in the chest and hypochondrium syndrome,which is effective on alleviating the clinical symptoms of TCM,and improving the quality of life of patients,without obvious toxicity or side effects.

OBJECTIVE: This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province. METHODS: We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed. RESULTS: The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α ^3.7/αα (50.23%) and β ^IVS-II-654/β ^N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively. CONCLUSION Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

AIM: To detect the expression of interleukin(IL)-36(α, β, γ)in tears of patients undergoing allogeneic hematopoietic stem cell transplantation(allo-HSCT), investigate its correlation with ocular surface microenvironment, and further analyze the relationship between its expression and ocular graft-versus-host disease(oGVHD).METHODS: Prospective study. A total of 35 patients(70 eyes)underwent allo-HSCT in the hematology department of our hospital in January 2020 were selected, and 35 healthy volunteers(70 eyes)with appropriate age and gender were selected as normal control group. The patients in the allo-HSCT group were followed up 3 times after operation once every 3mo. The subjects with postoperative ocular symptoms were divided into oGVHD and Non-oGVHD group.Ocular surface disease index(OSDI)questionnaire, Schirmer test, tear break-up time(TBUT), corneal fluorescein staining(FL), and conjunctival impression cytology(CIC)was conducted in three groups. Furthermore, the expression levels of IL-36(α,β,γ)in tears were detected by ELISA.RESULTS: In the normal control group, IL-36(α, β, γ)expression levels were 74.32±5.27, 70.02±8.43, 97.41±8.66 pg/mL, respectively; in the allo-HSCT group, IL-36(α, β, γ)baseline expression levels were 77.27±7.03, 74.53±7.53, 100.77±9.74 pg/mL, with no statistically significant differences between the two groups(t=1.648, 1.954, 1.262, all P>0.05). There were no significant differences in IL-36α, IL-36β and IL-36γ in Non-oGVHD group at different time points(P>0.05), while there were significant differences in IL-36α, IL-36β and IL-36γ in oGVHD group at different time points(P<0.05). Compared with Non-oGVHD group, the levels of IL-36α and IL-36β at different time points were significantly increased in oGVHD group(all P<0.05).IL-36(α, β, γ)of oGVHD group was positively correlated with OSDI score, FL and CIC, while it was negatively correlated with TBUT and Schirmer test(all P<0.05).CONCLUSION: Evaluation of levels of tear IL-36(α, β, γ)can be of significance in diagnosing oGVHD after allo-HSCT. IL-36(α, β, γ)is highly expressed in the tears of oGVHD patients before the onset of ocular symptoms, and it is correlated with the ocular surface parameters.

Objective: To investigate the lifespan of erythrocytes in megaloblastic anemia (MA) patients. Methods: A prospective cohort study analysis. Clinical data from 42 MA patients who were newly diagnosed at the Department of Hematology, Lanzhou University Second Hospital from January 2021 to August 2021 were analyzed, as were control data from 24 healthy volunteers acquired during the same period. The carbon monoxide breath test was used to measure erythrocyte lifespan, and correlations between erythrocyte lifespan and laboratory test indexes before and after treatment were calculated. Statistical analysis included the t-test and Pearson correlation. Results: The mean erythrocyte lifespan in the 42 newly diagnosed MA patients was (49.05±41.60) d, which was significantly shorter than that in the healthy control group [(104.13±42.62) d; t=5.13,P=0.001]. In a vitamin B₁₂-deficient subset of MA patients the mean erythrocyte lifespan was (30.09±15.14) d, and in a folic acid-deficient subgroup it was (72.00±51.44) d, and the difference between these two MA subsets was significant (t=3.73, P=0.001). The mean erythrocyte lifespan after MA treatment was (101.28±33.02) d, which differed significantly from that before MA treatment (t=4.72, P=0.001). In MA patients erythrocyte lifespan was positively correlated with hemoglobin concentration (r=0.373), and negatively correlated with total bilirubin level (r=-0.425), indirect bilirubin level (r=-0.431), and lactate dehydrogenase level (r=-0.504) (all P<0.05). Conclusions: Erythrocyte lifespan was shortened in MA patients, and there was a significant difference between a vitamin B₁₂-deficient group and a folic acid-deficient group. After treatment the erythrocyte lifespan can return to normal. Erythrocyte lifespan is expected to become an informative index for the diagnosis and treatment of MA.

This study aims to observe the effects of diosgenin on the expression of mammalian target of rapamycin(mTOR), sterol regulatory element-binding protein-1c(SREBP-1c), heat shock protein 60(HSP60), medium-chain acyl-CoA dehydrogenase(MCAD), and short-chain acyl-CoA dehydrogenase(SCAD) in the liver tissue of the rat model of non-alcoholic fatty liver disease(NAFLD) and explore the mechanism of diosgenin in alleviating NAFLD. Forty male SD rats were randomized into five groups: a control group, a model group, low-(150 mg·kg~(-1)·d~(-1)) and high-dose(300 mg·kg~(-1)·d~(-1)) diosgenin groups, and a simvastatin(4 mg·kg~(-1)·d~(-1)) group. The rats in the control group were fed with a normal diet, while those in the other four groups were fed with a high-fat diet. After feeding for 8 weeks, the body weight of rats in the high-fat diet groups increased significantly. After that, the rats were administrated with the corresponding dose of diosgenin or simvastatin by gavage every day for 8 weeks. The levels of triglyceride(TG), total cholesterol(TC), alanine transaminase(ALT), and aspartate transaminase(AST) in the serum were determined by the biochemical method. The levels of TG and TC in the liver were measured by the enzyme method. Oil-red O staining was employed to detect the lipid accumulation, and hematoxylin-eosin(HE) staining to detect the pathological changes in the liver tissue. The mRNA and protein levels of mTOR, SREBP-1c, HSP60, MCAD, and SCAD in the liver tissue of rats were determined by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR) and Western blot, respectively. Compared with the control group, the model group showed increased body weight, food uptake, liver index, TG, TC, ALT, and AST levels in the serum, TG and TC levels in the liver, lipid deposition in the liver, obvious hepatic steatosis, up-regulated mRNA and protein expression levels of mTOR and SREBP-1c, and down-regulated mRNA and protein expression levels of HSP60, MCAD, and SCAD. Compared with the model group, the rats in each treatment group showed obviously decreased body weight, food uptake, liver index, TG, TC, ALT, and AST levels in the serum, TG and TC levels in the liver, lessened lipid deposition in the liver, ameliorated hepatic steatosis, down-regulated mRNA and protein le-vels of mTOR and SREBP-1c, and up-regulated mRNA and protein levels of HSP60, MCAD, and SCAD. The high-dose diosgenin outperformed the low-dose diosgenin and simvastatin. Diosgenin may prevent and treat NAFLD by inhibiting the expression of mTOR and SREBP-1c and promoting the expression of HSP60, MCAD, and SCAD to reduce lipid synthesis, improving mitochondrial function, and promoting fatty acid β oxidation in the liver.

Objective: To explore the effects of expanded frontal-parietal pedicled flap in reconstructing cervical scar contracture deformity in children after burns. Methods: A retrospective observational study was conducted. From January 2015 to December 2020, 18 male children with cervical scar contracture deformity after burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, aged 4 to 12 years, including 10 cases with degree Ⅱ cervical scar contracture deformity and 8 cases with degree Ⅲ scar contracture deformity, and were all reconstructed with expanded frontal-parietal pedicled flap. The surgery was performed in 3 stages. In the first stage, a cylindrical skin and soft tissue expander (hereinafter referred to as expander) with rated capacity of 300 to 500 mL was placed in the frontal-parietal region. The expansion time was 4 to 6 months with the total normal saline injection volume being 2.1 to 3.0 times of the rated capacity of expander. In the second stage, expander removal, scar excision, contracture release, and flap transfer were performed, with the flap areas of 18 cm×9 cm to 23 cm×13 cm and the secondary wound areas of 16 cm×8 cm to 21 cm×11 cm after scar excision and contracture release. After 3 to 4 weeks, in the third stage, the flap pedicle was cut off and restored. The rated volume of placed expander, total normal saline injection volume, type of vascular pedicle of flap, survival of flap and reconstruction of scar after the second stage surgery were recorded. The neck range of motion and cervico-mental angle were measured before surgery and one-year after surgery. The appearance of neck, occurrence of common complications in the donor and recipient sites of children, and satisfaction of children's families for treatment effects were followed up. Data were statistically analyzed with paired sample t test. Results: All the patients successfully completed the three stages of operation. The rated volume of implanted expander was 300 mL in 6 children, 400 mL in 9 children, and 500 mL in 3 children, with the volume of normal saline injection being 630 to 1 500 mL. The type of vascular pedicle of flap was double pedicle in 13 cases and was single pedicle in 5 cases. All the flaps in 17 children survived well, and the secondary wounds after neck scar excision and contracture release were all reconstructed in one procedure. In one case, the distal blood supply of the single pedicled flap was poor after the second stage surgery, with necrosis of about 2.5 cm in length. The distal necrotic tissue was removed on 10 days after the operation, and the wound was completely closed after the flap was repositioned. In the follow-up of 6 months to 3 years post operation, the cervical scar contracture deformity in 18 children was corrected without recurrence. The flap was not bloated, the texture was soft, and the appearances of chin and neck were good. The range of motion of cervical pre-buckling, extension, left flexion, and right flexion, and cervico-mental angle in one year after operation were improved compared with those before operation (with t values of 43.10, 22.64, 27.96, 20.59, and 88.42, respectively, P<0.01). The incision in the frontal donor site was located in the hairline, the scar was slight and concealed. No complication such as cranial depression was observed in expander placement site, and the children's families were satisfied with the result of reconstruction. Conclusions: Application of expanded frontal-parietal pedicled flap in reconstructing the cervical scar contracture deformity in children after burns can obviously improve the appearance and function of neck, with unlikely recurrence of postoperative scar contractures, thus it is an ideal method of reconstruction.

Neonatal seizures are the most common clinical manifestations of critically ill neonates and often suggest serious diseases and complicated etiologies. The precise diagnosis of this disease can optimize the use of anti-seizure medication, reduce hospital costs, and improve the long-term neurodevelopmental outcomes. Currently, a few artificial intelligence-assisted diagnosis and treatment systems have been developed for neonatal seizures, but there is still a lack of high-level evidence for the diagnosis and treatment value in the real world. Based on an artificial intelligence-assisted diagnosis and treatment systems that has been developed for neonatal seizures, this study plans to recruit 370 neonates at a high risk of seizures from 6 neonatal intensive care units (NICUs) in China, in order to evaluate the effect of the system on the diagnosis, treatment, and prognosis of neonatal seizures in neonates with different gestational ages in the NICU. In this study, a diagnostic study protocol is used to evaluate the diagnostic value of the system, and a randomized parallel-controlled trial is designed to evaluate the effect of the system on the treatment and prognosis of neonates at a high risk of seizures. This multicenter prospective study will provide high-level evidence for the clinical application of artificial intelligence-assisted diagnosis and treatment systems for neonatal seizures in the real world.

T-cell acute lymphoblastic leukemia (T-ALL) is one of the most dangerous hematological malignancies, with high tumor heterogeneity and poor prognosis. More than 60% of T-ALL patients carry NOTCH1 gene mutations, leading to abnormal expression of downstream target genes and aberrant activation of various signaling pathways. We found that chidamide, an HDAC inhibitor, exerts an antitumor effect on T-ALL cell lines and primary cells including an anti-NOTCH1 activity. In particular, chidamide inhibits the NOTCH1-MYC signaling axis by down-regulating the level of the intracellular form of NOTCH1 (NICD1) as well as MYC, partly through their ubiquitination and degradation by the proteasome pathway. We also report here the preliminary results of our clinical trial supporting that a treatment by chidamide reduces minimal residual disease (MRD) in patients and is well tolerated. Our results highlight the effectiveness and safety of chidamide in the treatment of T-ALL patients, including those with NOTCH1 mutations and open the way to a new therapeutic strategy for these patients.

Objective: To investigate the relationship of polycyclic aromatic hydrocarbons (PAHs) exposure, S-adenosylhomocysteine hydrolase (SAHH) activity and long noncoding RNA H19 gene expression in the urine of coke oven workers. Methods: In September 2019, in a coking plant in Taiyuan City, 146 male workers who had worked in coke oven operations for one year were selected through a completely random sampling method, and their basic personal information was collected by questionnaire survey, and blood and urine samples were collected. The levels of 4 PAHs metabolites 2-hydroxfluorene (2-FLU), 2- hydroxynaphthalene (2-NAP), 9-hydroxyphenanthren (9-PHE), and 1-hydroxypyrene (1-OHP) in urine were detected by high performance liquid chromatography (HPLC) -fluorescence detection method. HPLC-UV detection method was used to detect the content of S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH) in plasma, and the SAHH activity value was obtained by calculating the ratio. Reverse transcription PCR method was used to determine the H19 gene expression level. Urine levels of 2-FLU, 2-NAP, 9-PHE, and 1-OHP were divided into Q(1), Q(2), Q(3), and Q(4) groups according to quartiles (P(25), P(50), P(75)). Regression, trend test and restricted cubic splines were used to analyze the relationship among PAHs metabolites, SAHH activity, H19 gene expression and their dose-response. Results: The median age of coke oven workers was 39.60 years old, the median length of service was 20.38 years, and the urinary levels of 2-FLU, 2-NAP, 9- PHE, and 1-OHP were 0.29, 0.74, 0.09, and 0.06 μg/mmol Cr, respectively. The levels of 2-FLU, 2-NAP and 9-PHE in the urine of workers were significantly different between groups with different 1-OHP levels (P<0.05). After adjusting for age, length of service, smoking, drinking, and levels of 2-FLU, 2-NAP and 9-PHE, SAHH activity decreased with the increase of urinary 1-OHP level (OR=0.63, 95%CI: 0.41-0.98, P=0.038), showing a nonlinear relationship (P(nonlinear)= 0.030). H19 gene expression increased with the increase of urinary 1- OHP level (OR=1.51, 95%CI: 1.03-2.19, P=0.033), there was a linear relationship (P(trend)= 0.058). The relationship between the other three metabolites in urine and SAHH activity and H19 gene expression was not statistically significant (P>0.05) . Conclusion: Urinary 1-OHP level may be a risk factor for decreased SAHH activity and increased H19 gene expression in coke oven workers.
