Objective To establish a RP-HPLC method for determination of aconitine in Shenhailong capsules.Methods Zorbax SB-C18column(4.6 mm?250 mm,5 ?m)was used,with(methanol∶water∶triethyl amine)60∶40∶0.1,as the mobile phase.The flow rate was 1.0mL?min-1and the column temperature was at 30℃.The detection wavelength was 240nm.Results Aconitine concentration presented a good linear range of 0.04?10-3～4?10-3g?L-1(r = 0.9999).with the average recovery of 98.4%,and RSD :1.0%.ConclusionThe method was accurate,nice in reproducibility and with few interference.It could be used for quality control of Shenhailong capsules.

ObjectiveTo investigate the antiviral effect of siRNA on herpes simplex virus type 2 (HSV-2) in vitro.MethodsDifferent siRNA duplexes targeting HSV-2 VP16 and DNA polymerase genes were designed and chemically synthesized.The antiviral effect of siRNA duplexes was evaluated by virus yield reduction assay.In detail,Vero cells cultured in 24-well plates were transfected with different siRNAs 4 hours before(preventive effect experiment) or 1 hour after(therapeutic effect experiment) the inoculation with HSV-2(0.02 to 0.05 plaque forming unit/cell).After additional culture for 40 to 48 hours,the expression of target genes in Vero cells was measured by real-time quantitative reverse transcription(RT)-PCR.Results Both the siRNA duplex VP2-1 targeting HSV-2 VP16 and DP2-1 targeting DNA polymerase gene resulted in a remarkable decrease in viral titer by about 1 log10 in both the preventive and therapeutic effect experiment.As the preventive effect experiment showed,the expression of HSV-2 VP16 mRNA was decreased markedly by 58.6％ and 79.5％ by VP2-1,respectively,and that of HSV-2 DNA polymerase mRNA by 59.8％and 77.4％ by DP2-1,respectively,at 6 and 12 hours after the infection.ConclusionsThe siRNA duplexes targeting HSV-2 VP16 and DNA polymerase genes could inhibit the proliferation of HSV-2.Hence,HSV-2 VP16 and DNA polymerase genes may serve as the target genes of RNA interference to inhibit HSV-2 replication.

A 38-year-old woman presented with a 20-year history of yellow papules and band-like atrophy on the right neck. The lesions developed slowly and were asymptomatic. There was no history of long-term sun exposure or family history of similar diseases. Skin examination revealed multiple irregularly sized yellow papules and plaques on the right anterior neck following cleavage lines, multiple pin cap-sized perifollicular papules on the posterior right neck. Well-defined band-like atrophic patches with fine wrinkling were observed in the whole right neck, giving an aged appearance. The skin of the left neck was nearly normal. Pathological examination of biopsy specimens from the yellow papules showed a normal epidermis, scant lymphohistiocytic and melanophage infiltrates around the vessels in the superficial dermis without solar degradation. The collagen bundles in the mid dermis were slightly thickened and arranged tightly in parallel to the skin surface with the absence of inflammatory infiltrate. Verhoeff-van Giesen's staining confirmed a nearly complete absence of elastic fibers in the mid dermis as well as obvious swelling and breakage of resident scant elastic fibers. Von Kossa's staining was negative. Based on the above findings, the diagnosis was made as unilateral mid-dermal elastolysis.

Objective To investigate the expression changes of aspartic proteinase (cathepsin D) and cysteine proteinase (cathepsin K) in photoaged fibroblasts. Methods The senescence of human fibroblasts was induced via culture in the presence of 8-methoxypsralen (MOP) of 50 mg/L in darkness for 24 hours followed by irradiation with UVA of 80 kJ/m~2. Then, aged fibroblasts were confirmed by senescence-associated β-galactosidase (SA-β-gal) staining. Real-time RT-PCR and Western blot were carried out to detect the mRNA and protein expressions of cathepsin D and cathepsin K in photoaged and normal control fibroblasts, respectively. Results Western blot showed a significant difference between photoaged and control fibroblasts in the grey scale of cathepsin D and cathepsin K (3.25 ± 0.33 vs 14.18 ± 2.25, f = 30.61, P < 0.01; 2.39 ± 0.66 vs 29.38 ± 4.62, t = 12.63, P< 0.01). The △Ct values for cathepsin D and cathepsin K mRNA were 2.79 ± 0.17 and -0.92 ± 0.06, respectively, in photoaged fibroblasts, significantly lower than those in the control fibroblasts (4.54 ± 0.34, 2.57 ± 0.13, t = 20.78, 28.50, respectively, both P < 0.01). According to the value of 2~(-△△Ct), the expression of cathepsin D and cathepsin K mRNA decreased 0.24 ± 0.021 and 0.09 ± 0.005 folds, respectively, in photoaged fibroblasts compared with the control fibroblasts. Conclusion The expression of cathepsin D and cathepsin K is decreased in photoaged fibroblasts.

Objective To explore the associations between vitamin D receptor ( VDR) Fok- Ⅰ and Apa- Ⅰ polymorphisms and myasthenia gravis (MG) in Chinese Han population.Methods Polymorphisms of VDR Fok- Ⅰ and Apa-Ⅰ were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.The frequencies of genotypes and hyplotypes were compared among 286 normal controls and 267 MG patients in different subgroups classified by gender,age of onset,presence of thymoma,and Osserman classification sat maximal severity in the follow-up.The association between the genotypes and maximal severity of MG and short-term glucocorticoid treatment were also investigated.Results There were no significant differences in frequencies of genotypes and hyplotypes of both Fok-Ⅰ and Apa-Ⅰ between MG group and control group,and among subgroups of MG.The Fok- Ⅰ showed no statistical difference between the patients with better and less improvement after short-term treatment of glucocorticoid.The frequency of Apa-Ⅰ alleles in the patients with better improvement (55/186,29.6% ) significantly differed from the less improved group ( 7/48,14.6%,OR = 2.46,95% CI 1.04-10.43,x2 = 4.400,P = 0.036).The patients with the genotype A A/Aa were more likely to improve better after the treatment(48/93,51.6%) than in the worse group(7/24,29.2%,OR =2.59,95% CI 0.98-14.60,x2 =3.858,P= 0.049).Conclusions Alleles and genotypes of VDR-Fok- Ⅰ and Apa-Ⅰ were not found to be related with MG onset and severity.MG patients with VDR-Apa-A allele may have better improvement short-term treatment of glucocorticoid.

OBJECTIVE: To analyze the genetic etiology of a Chinese pedigree affected with short stature. METHODS: A child with familial short stature (FSS) who had presented at the Ningbo Women and Children's Hospital in July 2020 and his parents and paternal and maternal grandparents were selected as the study subject. Clinical data of the pedigree was collected, and the proband was subjected to routine growth and development assessment. Peripheral blood samples were collected. The proband was subjected to whole exome sequencing (WES), and the proband, his parents and grandparents were subjected to chromosomal microarray analysis (CMA). RESULTS: The height of the proband and his father was 87.7cm (-3 s) and 152 cm (-3.39 s) respectively. Both of them were found to harbor a 15q25.3-q26.1 microdeletion, which has encompassed the whole of the ACAN gene which is closely associated with short stature. The CMA results of his mother and grandparents were all negative, and above deletion has not been included in population database and related literature, and was rated as pathogenic based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). After 14 months of rhGH treatment, the height of the proband has increased to 98.5 cm (-2.07 s). CONCLUSION The 15q25.3-q26.1 microdeletion probably underlay the FSS, in this pedigree. Short-term rhGH treatment can effectively improve the height of the affected individuals.
