Characteristics and Clinical Significance of Gene Mutation in Patients with Myelodysplastic Syndrome / 中国实验血液学杂志

OBJECTIVE@#To investigate the characteristics of gene mutations in patients with myelodysplastic syndromes (MDS) and its prognostic significance.@*METHODS@#High-throughput sequencing was used to detect 34 blood tumor-related genes in 210 patients with MDS, and the relationship with the revised International Prognostic Scoring System (IPSS-R) and the impact on prognosis of the patients were analyzed.@*RESULTS@#Among the 210 MDS patients, 142 cases (67.6%) showed mutations, and the first six genes with the highest mutation detection rate were ASXL1(20.5%), TET2(17.1%), U2AF1(14.3%), DNMT3A (11.9%), TP53(10.5%) and RUNX1(10.0%). The gene mutation rate of the patients in IPSS-R relatively high-risk group was higher than those in relatively low-risk group (P=0.001). Both TP53 and BCOR genes showed higher mutation rates in the higher risk group than in the lower risk group (P<0.05). Survival time of the patients in TP53 mutant group was lower than those in non-mutant group (P<0.001), survival time of patients in SF3B1 mutant group was higher than those in non-mutant group (P=0.018). According to the number of gene mutations, the patients could be divided into groups with 0-1, 2 and ≥3 gene mutations, and the median OS of the three groups were not reached, 43 and 27 months, respectively (P=0.004). The Multivariate analysis showed that the increasing number of gene mutations and TP53 mutation was the independent risk factors affecting prognosis of the patients, while SF3B1 mutation was the independent protective factor for the prognosis of the patients.@*CONCLUSION@#The gene mutation rate was higher in MDS patients. And the increasing numbers of gene mutation, TP53 and SF3B1 were the influence factors of prognosis in the patients.

Effect of Dingkundan on Sex Hormone and Follicle Count in Mice of Tripterygium Wilfordii Polyglycosides Induced Diminished Ovarian Reserve / 中国实验方剂学杂志

Objective:To establish a mouse model of diminished ovarian reserve （DOR） induced by tripterygium wilfordii polyglycosides （TWP）， and to explore the therapeutic effect of Dingkundan （DKD） on DOR， so as to provide scientific basis for its clinical application. Method:The 60 female Blab/c mice with regular estrous cycle were randomly divided into blank group， model group， low，medium and high-dose DKD group， DKD group and estradiol valerate group， with 10 mice in each group. Except the blank group， the other groups were given 40 mg·kg-1 TWP suspension. Meantime，low，medium and high-dose DKD group were given 1.64，3.28，6.56 g·kg-1 DKD suspension respectively， and estradiol valerate group was given 0.15 mg·kg-1 estradiol valerate suspension by gastric lavage once a day for 30 days. The general condition， body weight， estrous cycle and gonad index of mice were observed， serum follicle-stimulating hormone （FSH）， luteinizing hormone （LH） and estradiol （E2） were determined by radioimmunoassay， ovarian morphology and follicle count were observed by hematoxylin-eosin staining （HE） staining. Result:Compared with the blank group， most of the mice in model group had disordered estrous cycle， uterine and ovarian indexes decreased （P<0.05）， serum FSH increased （P<0.05）， LH was on an upward trajectory， E2 was on a downward trend， and the number of growth follicles and corpus luteum decreased and the number of atresia follicles increased（P<0.05）. Compared with the model group， half of the mice in DKD group resumed regular estrous cycle， however， the estrous cycles of mice in estradiol valerate group were stagnated during estrous period. In medium-dose， high-dose DKD group and estradiol valerate group， the uterine and ovarian indexes of the mice were increased， the serum FSH value decreased （P<0.05） and serum LH was on a downward trend， high-dose DKD group and estradiol valerate group increased the levels of serum E2 （P<0.05）. In DKD group， the number of growth follicles and corpus luteum were increased and the number of atresia follicles were reduced （P<0.05）， with the best effect at medium dosage. And in estradiol valerate group， the number of primitive follicles， sinusoidal follicles and corpus luteum were increased （P<0.05）， but the number of atresia follicles had no difference to the model group. Conclusion:DKD can improve serum sex hormones， promote follicular development and reduce follicular atresia， which can play a therapeutic role in the treatment of DOR.

Establishment of premature ovarian insufficiency kidney deficiency and blood stasis pattern mouse model with Tripterygium wilfordii polyglycoside for Bushen Culuan Decoction therapy / 中国中药杂志

To establish a mouse model of premature ovarian insufficiency( POI) with kidney deficiency and blood stasis pattern by Tripterygium wilfordii polyglycoside( TWP) gavage,and to evaluate the ovarian function and fertility of the model,in order to find Bushen Culuan Decoction therapeutic mechanism. 60 SPF level Blab/c female mice with normal estrous cycle were randomly divided into 6 groups of 10 each: blank group 1( BG1),blank group 2( BG2),blank fertility group( BFG),model group( MG),model recovery group( MRG) and model fertility group( MFG). The mice in three model groups were treated by gastric gavage with TWP suspension 40 mg·kg-1 twice a day for 14 days,while the mice in three blank groups were treated by gastric gavage with same volume normal saline for 14 days. The mice in BG1 and MG were sacrificed and dissected on day 15. The mice in BG2,BFG,MRG and MFG were returned normal feeding from day 15 and were sacrificed and dissected on day 29. The mice in BFG and MFG were cohabited with male mice with a ratio of 2 ∶1( female ∶male) from day 15. The general situation and estrous cycles of all mice were observed every day. Serum sex hormone levels,ovarian index,uterine index,ovarian morphology,follicle count,ovarian VEGF and ES index were observed within the mice in BG1,BG2,MG and MRG. Pregnancy rate,litter size,survival number of newborn mice and male-female proportion were reported within the mice in BFG and MFG. In model establishing stage,the body weight of mice significantly decreased( P <0. 05) in MG and MFG. Compared with BG1,the mice in model group had irregular estrous cycle,decreased ovarian and uterine indexes,less primordial and developing follicles,more atretic follicles,increased VEGF expression and decreased ES expression( P <0. 05). Compared with blank group 2,the mice in model recovery group had irregular estrous cycle,increased FSH level,decreased ovarian indexes,less primordial and developing follicles,more atretic follicles,increased VEGF expression( P<0. 05). Compared with blank fertility group,the mice in model fertility group had smaller litter size and newborn mice survival count( P<0. 05). Gastric gavage with TWP 40 mg·kg-1 twice a day for 14 days is a feasible way to establish a POI kidney deficiency and blood stasis pattern mouse model. The mice ovarian functions didn't recovery on day 14 after stopping TWP intervening,which could suggest the effectiveness of subsequent therapeutic intervention.

Infertility caused by salpingitis treated based on theory of kidney deficiency and blood stasis / 中国中药杂志

Infertility caused by salpingitis is one of the main causes of secondary infertility in women. In recent years,the incidence has been increasing year by year. Modern medicine believes that this disease is a complication due to incomplete or delayed treatment of acute and chronic salpingitis,with no satisfactory drug therapy at present. Clinical therapies mainly include surgical treatment,interventional treatment and assisted reproductive technology. After summarizing the experience of predecessors and the clinical practice of treating infertility for many years,the author considers that the disease location is the cell veins,and the nature is mostly mixed of deficiency and excess. Kidney deficiency and blood stasis are the main pathogenesis of infertility caused by salpingitis. Blood stasis is the pathological basis,while kidney deficiency is the fundamental pathogenesis. Long-term kidney deficiency will lead to blood stasis,and blood stasis will aggravate kidney deficiency. Both of them are cause and effect to each other. Infertility caused by salpingitis is difficult to cure. Based on the theory of kidney deficiency and blood stasis,the basic principles of clinical treatment are tonifying kidney and activating blood circulation,removing blood stasis and dredging collaterals. Oral administration with traditional Chinese medicine combined with external therapies,such as enema,external application,acupuncture and moxibustion,have been achieved a good efficacy in repairing fallopian tube function and improving pregnancy rate. Therefore,the treatment of infertility caused by salpingitis based on " kidney deficiency and blood stasis" is worthy of further discussion in both clinical and experimental aspects.

Clinical application evaluation and revision suggestions of clinical practice guideline on traditional Chinese medicine therapy alone or combined with antibiotics for pelvic inflammatory disease / 中国中药杂志

To evaluate the clinical application of clinical practice guideline on traditional Chinese medicine therapy alone or combined with antibiotics for pelvic inflammatory disease and provide reference for the revision of the Guideline. Questionnaire research was conducted from applicability and application evaluation. A total of 1 311 copies of valid questionnaires were obtained, including 717 questionnaires on applicability evaluation and 594 questionnaires on application evaluation. There were 83 items from 4 aspects in the applicability questionnaire. In statistical agreement rates of those items to reflect the application status of the Guideline, the rates of 8 items were all more than 95% except for rates of "content integrity", "comparison with the diagnosis and treatment scheme of his/her unit (individual)" and "economy of clinical application", 94.70%, 93.86% and 93.17% respectively. In statistical agreement rates of those items to reflect the quality of the Guideline, the rates of 3 items were all more than 97%, except the rate of "whether syndrome classification is reasonable" item was 95.26%. Among the items that reflect the local purchase difficulty and price evaluation of Chinese patent medicine recommended in the Guideline, most clinicians thought the prices were modest. There were 56 items from 6 aspects in the application evaluation questionnaire. In statistical agreement rates of those items to reflect the application rationality of the Guideline, the rates of 3 items were all more than 96%, except rate of "whether syndrome classification is reasonable" item was 91.58%. In statistical agreement rates of those items to reflect the clinical application effect of the recommended regimen in the Guideline, the traditional application of traditional Chinese medicine decoction had generally better application effect, whereas Chinese patent medicines were less effective. In statistical agreement rates of those items to reflect the overall evaluation of clinical application, the rates of "overall effect" and "overall safety" were all more than 96%, except the rates of "overall economy" item was 92.42%. It indicates that the overall effect of this Guideline is relatively well. It is suggested to improve the classification of syndrome differentiation and increase the species of Chinese medicine decoction and Chinese patent medicines, and to standardize the duration and course of medication. The next revised work should not only uptake the experiences of prominent TCM doctors and all kinds of research achievements, but also regularly update and strengthen the publicity of the Guideline.

<p><b>OBJECTIVE</b>To explore the effects of Huqi Extractum (HQE) on the viability and apoptosis in mouse thymic lymphocytes against 60Co radiation.</p><p><b>METHODS</b>Thymic lymphocytes were isolated from 4 -8 weeks healthy male Kunming mice and primarily cultured. Then they were divided into the control group, the irradiation group, the low dose HQE group, the medium dose HQE group, and the high dose HQE group. Equal volume of serum free RPMI-1640 culture solution was added in the control group and the irradiation group, while equal volume of HQE solution (at the daily dose of 25, 50, and 100 mg/mL) was respectively added in the low, medium, and high dose HQE groups. Except the control group, those in the rest groups were exposed radiation at a single dose of 5 Gy gamma-ray. Changes of the thymic lymphocytes' viability were measured by MTT colorimetric assay at 12, 24, 36, and 48 h after radiation. The early apoptosis rate was detected using flow cytometry (FCM) after 10-h radiation. The apoptosis was detected using agarose gel electrophoresis to observe the DNA injury after 24-h radiation.</p><p><b>RESULTS</b>The viability level decreased more obviously in the irradiation group than in the control group at 24 -48 h after radiation (P < 0.01, P < 0.05). The average viability level was obviously higher in the low, medium, and high dose HQE groups than in the irradiation group (P < 0.05) in a dose dependent manner. The early apoptosis rate was obviously lower in the low, medium, and high dose HQE groups than in the irradiation group, with statistical difference shown in the high dose HQE group (P < 0.01). Typical DNA ladder fragments were found in the electrophoresis in all groups except the control group. But the DNA injury was comparatively milder in the low, medium, and high dose HQE groups, with more obvious effects shown in the high dose HQE group.</p><p><b>CONCLUSION</b>HQE showed protection for the viability of early thymic lymphocytes exposed to the 60CO radiation, and could lower the early apoptosis level.</p>

Characterization of S gene of a strain of hantavirus isolated from Apodemus peninsulae in Heilongjiang Province / 病毒学报

In order to study the molecular characterization of the hantavirus isolated from Apodemus peninsulae in Heilongjiang Province, the S gene of a new strain NA33 was amplified, sequenced and analyzed. The results showed that the complete nucleotide sequence of the S gene of NA33 strain was composed of 1 693 nucleotides with TA-rich. The S gene contained one ORF, starting at position 37 and ending at position 1 326, encoding the N protein of 429 amino acid residues, and in line with HTN-based coding. Sequence comparison of the S genes between NA33 and reference hantavirus strains showed that NA33 was more homologous to Amur-like viruses than to the Hantaan (HTN) viruses or the other hantaviruses. Phylogenetic analysis of the amino acid sequence of N proteins showed that NA33 was clustered into the group of Amur-like viruses and was more similar to Far East Russia and Jilin strains isolated from Apodemus peninsulae. The phylogenetic tree indicated a certain degree of host-dependent characteristics and geographical aggregation characteristics of hantanviruses. Furthermore, the amino acid sequence of N protein of NA33 had the conserved amino acid sites of Amur-like viruses. In conclusion, Apodemus peninsulae carried Amur-like viruses in Heilongjiang province and was an important infectious source of hemorrhagic fever with renal syndrome (HFRS).
