Objective To investigate the relationship between single nucleotide polymorphisms(SNPs)in the eNOS gene and genetic susceptibility to systemic lupus erythematosus(SLE)in Hainan.Methods Blood samples were collected from SLE patients(SLE group,n=214)and healthy controls(control group,n=214)from January 2020 to December 2022 at the First Affiliated Hospital of Hainan Medical College and Hainan Provincial People's Hospital.The bases of eNOS gene rs3918188,rs1799983 and rs1007311 loci in each group were detected by SNaPshot sequencing technology.Logistic regression was used to analyze the correlation between genotypes,alleles and gene models(dominant model,recessive model,and overdominant model)of the above 3 target loci of the eNOS gene and genetic susceptibility to SLE.Haplotype analysis was conducted using HaploView 4.2 software to investigate the relationship between haploid and genetic susceptibility to SLE at each site.Results The results of logistic regression analysis revealed that the CC genotype and the C allele at rs3918188 locus were risk factors for genetic susceptibility to SLE(CC vs.AA:OR=2.449,P<0.05;C vs.A:OR=2.133,P<0.001).In recessive model at rs3918188 locus,CC genotype carriers had an increased risk of SLE development compared with AA+AC genotype carriers(OR=2.774,P<0.001).In contrast,in overdominant model at this locus,AC genotype carriers had a decreased risk of SLE occurrence compared with AA+CC genotype carriers(OR=0.385,P<0.001).In addition,polymorphisms of rs1799983 and rs1007311 were not associated with susceptibility to SLE in genotype,allele type and the 3 genetic models(P>0.05).Haplotype analysis revealed a strong linkage disequilibrium between the rs1007311 and rs1799983 loci of the eNOS gene,but no significant correlation was found between haplotype and genetic susceptibility to SLE(P>0.05).Conclusion The CC genotype and C allele at rs3918188 locus of eNOS gene may be risk factors for SLE in Hainan,while the risk of SLE occurrence is reduced in carriers of AC genotype under the overdominant model.

OBJECTIVE:
To compare the therapeutic effect between Fanzhen Jieci (warming acupuncture plus fast needling) combined with conventional acupuncture and simple conventional acupuncture on discogenic sciatica.
METHODS:
A total of 76 patients with discogenic sciatica were randomized into a Fanzhen Jieci group and a conventional acupuncture group, 38 cases in each one. Conventional acupuncture was applied at Shenshu (BL 23), Dachangshu (BL 25), L1-L5 Jiaji (EX-B 2) and Huantiao (GB 30) on the affected side, etc. in the conventional acupuncture group. On the basis of the treatment in the conventional acupuncture group, Fanzhen Jieci was applied at L1-L5 Jiaji (EX-B 2) and Huantiao (GB 30) on the affected side in the Fanzhen Jieci group, i.e. warming acupuncture was applied at L1-L5 Jiaji (EX-B 2), and fast needling was applied at Huantiao (GB 30) on the affected side for a depth of 40-60 mm, so as to introduce a sensation of electric shock transmitting to lower limb, and then the needle was immediately withdrawn. The treatment was given once every other day, 3 times a week for 3 weeks in both groups. The visual analogue scale (VAS) score of leg and low back pain, the Oswestry disability index (ODI) score and the 36-item short form health survey (SF-36) score before and after treatment were compared between the two groups.
RESULTS:
Compared before treatment, the VAS scores of leg and low back pain and the ODI scores after treatment were decreased in both groups (P<0.001), the changes of the VAS scores of leg and low back pain in the Fanzhen Jieci group were larger than those in the conventional acupuncture group (P<0.05). After treatment, except for the role emotional and health transition scores, the various scores of SF-36 were increased compared before treatment in the Fanzhen Jieci group (P<0.01); except for the role physical, role emotional and health transition scores, the various scores of SF-36 were increased compared before treatment in the conventional acupuncture group (P<0.01). After treatment, the physical functioning, role physical, bodily pain, mental health and general health scores of SF-36 in the Fanzhen Jieci group were higher than those in the conventional acupuncture group (P<0.05).
CONCLUSION
Fanzhen Jieci combined with conventional acupuncture can effectively relieve the pain and improve the mental state in patients with discogenic sciatica, its therapeutic effect is superior to simple conventional acupuncture.

The classical famous prescription Dajianzhong Decoction is recorded in Synopsis of the Golden Chamber written by Zhang Zhongjing in the Eastern Han Dynasty. It has a long history and definite clinical effects, while this prescription has not been manufactured into Chinese patent medicine preparation. We collected many ancient books of traditional Chinese medicine(TCM) by using the method of bibliometrics and got 211 valid data terms which involved 67 ancient books. The history, main treated syndromes, formulation principle, origins and processiong of medicinal materials, and decoction method of Dajianzhong Decoction were analyzed. Despite the different views of various generations of medical experts toward the composition of this prescription, the compatibility ratio of Ginseng Radix et Rhizoma to Zingiberis Rhizoma Recens is constant. Furthermore, we explored the origins of synonyms of Dajianzhong Decoction. On the basis of this study, we hope to gain an insight into the research and development of the compound preparations of Dajianzhong Decoction and provide reference for the heritage and innovation of other classical prescriptions.

OBJECTIVES:
To investigate the distribution of body mass index (BMI) and risk factors for obesity in children with Diamond-Blackfan Anemia (DBA).
METHODS:
The children with DBA who attended National Clinical Research Center for Blood Diseases, Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, from January 2003 to December 2020 were enrolled as subjects. The related clinical data and treatment regimens were recorded. The height and weight data measured within 1 week before or after follow-up time points were collected to calculate BMI. The risk factors for obesity were determined by multivariate regression analysis in children with DBA.
RESULTS:
A total of 129 children with DBA were enrolled, among whom there were 80 boys (62.0%) and 49 girls (38.0%), with a median age of 49 months (range 3-189 months). The prevalence rate of obesity was 14.7% (19/129). The multivariate logistic regression analysis showed that the absence of ribosomal protein gene mutation was closely associated with obesity in children with DBA (adjusted OR=3.63, 95%CI: 1.16-11.38, adjusted P=0.027). In children with glucocorticoid-dependent DBA, obesity was not associated with age of initiation of glucocorticoid therapy, duration of glucocorticoid therapy, and maintenance dose of glucocorticoids (P>0.05).
CONCLUSIONS
There is a high prevalence rate of obesity in children with DBA, and the absence of ribosomal protein gene mutation is closely associated with obesity in children with DBA.

Journal of Southern Medical University 2022;42(5):752-759
OBJECTIVE:
To investigate the protective effect of fucoxanthin (FX) against diabetic cardiomyopathy and explore the underlying mechanism.
METHODS:
Rat models of diabetes mellitus (DM) induced by intraperitoneal injection of streptozotocin (60 mg/kg) were randomized into DM model group, fucoxanthin treatment (DM+FX) group and metformin treatment (DM+ Met) group, and normal rats with normal feeding served as the control group. In the two treatment groups, fucoxanthin and metformin were administered after modeling by gavage at the daily dose of 200 mg/kg and 230 mg/kg, respectively for 12 weeks, and the rats in the DM model group were given saline only. HE staining was used to examine the area of cardiac myocyte hypertrophy in each group. The expression levels of fibrotic proteins TGF-β1 and FN proteins in rat hearts were detected with Western blotting. In the cell experiment, the effect of 1 μmol/L FX on H9C2 cell hypertrophy induced by exposure to high glucose (HG, 45 mmol/L) was evaluated using FITC-labeled phalloidin. The mRNA expression levels of the hypertrophic factors ANP, BNP and β-MHC in H9C2 cells were detected using qRT-PCR. The protein expressions of Nrf2, Keap1, HO-1 and SOD1 proteins in rat heart tissues and H9C2 cells were determined using Western blotting. The DCFH-DA probe was used to detect the intracellular production of reactive oxygen species (ROS).
RESULTS:
In the diabetic rats, fucoxanthin treatment obviously alleviated cardiomyocyte hypertrophy and myocardial fibrosis, increased the protein expressions of Nrf2 and HO-1, and decreased the protein expressions of Keap1 in the heart tissue (P < 0.05). In H9C2 cells with HG exposure, fucoxanthin significantly inhibited the enlargement of cell surface area, lowered the mRNA expression levels of ANP, BNP and β-MHC (P < 0.05), promoted Nrf2 translocation from the cytoplasm to the nucleus, and up-regulated the protein expressions its downstream targets SOD1 and HO-1 (P < 0.05) to enhance cellular antioxidant capacity and reduce intracellular ROS production.
CONCLUSION
Fucoxanthin possesses strong inhibitory activities against diabetic cardiomyocyte hypertrophy and myocardial fibrosis and is capable of up-regulating Nrf2 signaling to promote the expression of its downstream antioxidant proteins SOD1 and HO-1 to reduce the level of ROS.

Purpose:
Capecitabine is an extensively used oral prodrug of 5-fluorouracil in treatment of colon cancer and is known to cause hand-foot syndrome (HFS). As the target enzyme for capecitabine, thymidylate synthase (TYMS) plays a key role for 5-fluorouracil metabolism and has been associated with some side effects caused by capecitabine. The aim of our study is to identify the possible genetic predictors of capecitabine-induced HFS (CAP-HFS) in Chinese colorectal cancer patients.
Materials and Methods:
Whole exons of TYMS were sequenced for 288 extreme phenotype HFS patients, including 144 severe or early-onset (first 2 cycles) moderate HFS extreme cases and 144 extreme controls with no reported HFS. The associations between polymorphisms and CAP-HFS were analyzed using logistic regression under an additive model.
Results:
We identified a novel risk mutation (c.1A>G, chr18:657743), was associated with severe HFS in an extreme case who was affected during the first cycle of treatment. Moreover, we identified three new variants, rs3786362, rs699517, rs2790, and two previously reported variants, 5’VNTR 2R/3R and 3′-untranslated region 6-bp ins-del, which were significantly associated with CAP-HFS (p < 0.05). In silico analysis revealed that the effect of these polymorphisms in the TYMS region on the development of HFS might not be restricted solely to the regulation of TYMS expression, but also the TYMS catalytic activity through the indirect effect on ENOSF1 expression.
Conclusion
This study identified new polymorphisms in TYMS gene significantly associated with CAP-HFS, which may serve as useful genetic predictors for CAP-HFS and help to elucidate the underlying mechanism of HFS.
