Objective To investigate the clinical presentation,laboratory features,imaging findings and CYP27A1 gene mutations of cerebrotendinous xanthomatosis (CTX) for improving the recognition and the early diagnosis and treatment of the disease.Methods Medical records and 8 months follow-up data of one patient who had been clinical diagnosed as CTX were collected and the pedigree and gene mutation analysis of the patient were carried out.Meanwhile,the clinical characters of CTX were analyzed according to the data from our patient and the review of the literature. Results Patient was a 36 years old male manifested with mental retardation, bilateral corticospinal tract and corticonuclear tract impairment,cerebellar lesions and peripheral neuropathy; head MRI indicated symmetric abnormal signals of bilateral basal ganglia,cerebellar dentate nucleus softening and calcification lesions; Achilles tendon MRI indicated markedly thickened Achilles tendon; gene mutation analysis showed sterol-27-hydroxylase gene( CPY27A1 )C→T homozygous mutation in 1016 nucleotide of exon 5.Ursodesoxycholic acid was given as treatment.In 8 months of follow up,for the first 6 months,the patient took medicine regularly and the illness condition was stable.But for the nearly 2 months,the patient voluntarily stopped medicine and the illness condition was worse.Conclusions CPY27A1 gene C→T homozygous mutation in 1016 nucleotide of exon 5 leads to CTX in the patient, which conforms to the characteristic of autosomal recessive disorder. CTX has some characteristic clinical manifestations,such as Achilles tendon thickening,intelligent declining and so on.But lack of specificity of early radiographic examination makes CTX easy to be delayed diagnosis and treatment.CYP27A1 gene mutation analysis has an important significance for early diagnosis of CTX,which should be paid more attention,while the early application of chenodeoxycholicacid treatment can delay the progression of the disease.

Aim To study the inhibitory effect of ginkgolide B (BN52021) on the PAF induced changes of chemotaxis of murine peritoneal macrophages and the related polymerization of F-actin.Methods Chemotaxis assays were performed using a modified 48-well Boyden chamber. Actin polymerization of murine peritoneal macrophages was analyzed by flow cytometry using a specific fluorescent stain. Results Peritoneal macrophages significantly migrated toward platelet-activating factor(PAF) through a micropore filter; however, in the presence of PAF receptor antagonist BN52021 (0. 01the actin polymerization of murine peritoneal macrophages induced by PAF in the presence of Ca2+ , but not in Ca2+ -free medium. Conclusion The results suggested that preventing polymerization of F-actin may be a pathway by BN52021 to inhibit the chemotaxis of macrophages, and this effect seems to be Ca2+dependent. The data further indicated that inhibition of PAF induced macrophage chemotaxis is an important mechanism underlying the anti-inflammatory action of BN52021.

Abstract: Objective To investigate the type and distribution of drug resistance of Mycobacterium tuberculosis (MTB) in Hainan tuberculosis hospital from 2019 to 2021, and to provide reference for the development of drug resistant tuberculosis prevention and control strategy. Methods From 2019 to 2021, a total of 1 687 strains of sputum were isolated and cultured and identified as MTB. Drug sensitivity testing was performed on eight anti-tuberculosis drugs: isoniazid (INH), rifampicin (RFP, R), ethambutol (EMB), streptomycin (SM), kanamycin (KM), capreomycin (CPM), ofloxacin (OFX), and propylthioisoniacamide (PTO). The drug resistance analysis was conducted. Results Among the 1 687 MTB strains, the overall drug resistance rate was 41.32% (697), with a single drug resistance rate of 11.62% (196), a multi-drug resistance rate of 4.10% (69), a extensive drug resistance rate of 23.71% (400), a pan-drug resistance rate of 1.90% (32), and a rifampicin
resistance rate of 28.10% (474), and the main drug resistance types were extensive drug resistance and rifampicin resistance. The order of resistance to the eight drugs was OFX (64) > SM (62) > INH (48) > RFP (19) > CPM (2) > KM (1) > EMB (0) and PTO (0). The rate of resistance to INH and RFP of first-line drugs in newly treated patients was lower than that in retreated patients (χ2=0.110, 0.765; P>0.05); the rate of resistance to second-line drugs OFX, CPM and KM in initially treated patients was lower than that in retreated patients (χ2=1.037, 1.212, 1.653; P>0.05). The total drug resistance rate in 2019 was 51.16%, which was higher than that in 2020 (35.08%) and 2021 (38.89%). The difference between groups was significant (χ2=29.25,16.60; P=0.000), but there was no significant difference in overall drug resistance rate between 2020 and 2021 (χ2=1.823, P=0.177). Among the occupational types of tuberculosis patients, farmers were the main ones, accounting for 56.25% (949). The patients with drug-resistant tuberculosis were mainly distributed in Haikou City (165) > Wanning City (72) > Chengmai County(64) > Wenchang City (51) = Dongfang City (51) > Danzhou City (48), and patients in these six areas accounting for 64.71%(451/697). Conclusions The drug resistance rate of tuberculosis in Hainan Province is relatively high, with OFX and SM resistance being the main types of drug resistance. The extensive drug resistance rate is higher than the national average level. Therefore, surveillance and treatment should be strengthened and optimized to reduce the prevalence of drug-resistant tuberculosis.

Objective To analyze the relationship between karyotypes and clinic features of patients with primary amenorrhea. Method Karyotype analysis of patients with primary amenorrhea was performed by using G-banding technique. Results Karyotype analysis of 468 patients with primary amenorrhea revealed that 255 patients (54. 49% ) had normal female karyotypes and 213 patients (45.51%) had abnormal karyotypes, including 143 patients with abnormal X chromosome, 4 patients with mosaic X -Y chromosome, 57 patients with 46, XY karyotype, 8 patients with abnormal autosome and one patient with Xautosome translocation. 75.52% primary amenorrhea patients with short stature had abnormal X chromosome, and all primary amenorrhea patients with deletion or break-up of Xp11. 1 - 11.4 and Xp21 - 22 were short statures. Conclusion One of the main reasons of primary amenorrhea was chromosome abnormity,especial heterosome abnormity. Karyotype analysis should be used to detect primary amenorrhea patients in regular. There might be relationship between height improvement and the abnormity of Xp11. 1 - 11.4 and Xp21 - 22.
