OBJECTIVE:To explore the effects of inhaled budesonide on the efficacy and related indexes of patients with acute bronchitis. METHODS:102 patients with acute bronchitis were randomly divided into control group and observation group. Control group was given 100 mg/(kg·d) Cefotaxime sodium injection,adding into 150 ml 0.9% Sodium chloride injection intravenously by 2 times,as well as sedation,oxygen inhalation,rehydration,correcting acid-base balance and other conventional treatment;ob-servation group was additionally given 2 ml Inhaled budesonide suspension,twice a day. The treatment course for both groups was 7 d. Clinical efficacy,erythrocyte immune complex rosette(E-ICR),high-sensitivity C-reactive protein(hs-CRP),peak expiratory flow rate(PEF),forced vital capacity(FVC),1 second forced exhaled volume(FEV1),time of body temperature returned to nor-mal,cough disappearance time,rale disappearance time before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,time of body temperature returned to normal, cough disappearance time and rale disappearance time were significantly shorter than control group,the differences were statistically significant(P<0.05). Before treatment,there were no significant differences in the E-ICR and hs-CRP levels,PEF,FVC and FEV1 between 2 groups(P>0.05). After treatment,E-ICR and hs-CRP levels were significant-ly lower than before,and observation group was lower than control group,PEF,FVC and FEV1 were significantly higher than be-fore,and observation group was higher than control group,the differences were statistically significant(P<0.05). And there were no adverse reactions during treatment. CONCLUSIONS:Based on conventional treatment,inhaled budesonide has obvious efficacy in the treatment of acute bronchitis,and it can reduce E-ICR and hs-CRP,improve pulmonary functions,with good safety.

Clinical study of modified Ganmai Dazao decoction in the treatment of yang deficiency climacteric depression and observe the effects of modified Ganmai Dazao decoction on neuroendocrine system in patients with yang deficiency climacteric depression. 86 cases were randomly divided into treatment group treated with modified Ganmai Dazao decoction and control group treated with Deanxit. The curative effect was evaluated with Hamilton's depressive scale (HAMD) and pittsburgh sleep quality scale (PSQI) before and at the end of the two and four weeks of the treatment, the serum levels of serotonin (5-HT), norepinephrine (NE), estradiol (E2), follicle stimulating hormone (FSH), luteotropic hormone (LH) were detected before and after the four weeks of the treatment The results showed that the total effective power of treatment group was 88.4% and the total effective power of control group was 81.4% after four weeks interference, with insignificant difference between the two groups. After two and four weeks of the treatment, the score of HAMD decreased remarkably in both groups (P < 0.01), with insignificant difference between the two groups in same phase. After two and four weeks of the treatment, the total score of PSQI decreased remarkably in both groups (P < 0.05), with significant difference between the two groups after four weeks (P < 0.01). After four weeks of treatment, the serum levels of 5-HT and NE increased (P < 0.01), with insignificant difference between the groups. After four weeks of treatment, the serum levels of E2 increased obviously (P < 0.05), the levels of FSH decreased obviously (P < 0.05), the levels of LH decreased insignificant, with insignificant difference between two groups. This study indicates that modified Ganmai Dazao decoction has obvious therapeutic effects in the treatment of climacteric depression, and showed equivalent efficacy with Deanxit, and modified Ganmai Dazao decoction has better effect on improving the sleep quality in patients than Deanxit, the effect of improved clinical symptoms may be through adjusted levels of 5-HT, NE, E2, FSH and LH of climacteric depression.

Myelodysplastic syndromes (MDS) are heterogeneous clonal hematopoietic stem cell disorders with different mechanisms and diverse prognosis. The excess of ring sideroblasts (RS) is an important presentation MDS, but the mechanisms of RS appearance are obscure and the treatment of MDS-RS is intractable. Splicing factors play a very important role in the maturation process of eucaryon mRNA, recent studies indicate that there is a significant causal relationship between splicing factor 3B subunit 1 (SF3B1) mutation and the presence of ring sideroblasts. Lucubrating the downstream molecular of the mutated SF3B1 can facilitate exploring the mechanisms and new therapeutic strategies of MDS-RS.

OBJECTIVETo explore the characteristics of CpG islands methylation at promoter region of HOX A gene cluster in leukemia cells before and after all-trans retinoic acid (ATRA) treatment.

METHODSEleven human leukemia cell lines, bone marrow cells from leukemia patients before and after therapy and white blood cells from normal subjects were collected. HL-60 and K562 cells were treated by 2-deoxy-5-azacytidine (DAC) or ATRA respectively. Bisulfite modified DNA of these cells were amplified with PCR and quantitatively analyzed by pyrosequencing for methylation of CpG islands.

RESULTSIn normal cells, CpGs at all loci of HOX A cluster were unmethylated. In HOX A4, A6, A7, A9, A10 and A11, many CpG sites were methylated (>20%) or hypermethylated (>50%) in leukemia cell lines. Percentages of methylated CpGs were higher in T-cell leukemia (71.4%) and B-cell leukemia (85.7%) than in others. For individual CpGs methylations there were HOX A4 in all leukemia cells, HOX A6 and HOX A7 in most of the leukemia samples and HOX A10 and HOX A11 in K562 and HL-60 cells (38%-86%). HOX A9 CpGs showed hypomethylation in most of myeloid leukemia cells, whereas HOX A11 CpGs were hypermethylated in B-cell leukemia (>50%). Methylation levels of HOX A4 and A6 in AML and ALL patients after complete remission were decreased obviously, and so did HOX A6 and A9 in CML patients. Methylation levels of HOX A4, A6 and A10 in HL-60 cells and of HOX A6 in K562 cells were reduced by ATRA treatment.

CONCLUSIONSIn all leukemia cell lines, aberrant methylation of CpGs was observed at promoter regions of 6 HOX A cluster genes, and some of these genes showed leukemia-type-specific hypermethylation. CpGs methylation of some HOX A genes in leukemia cell lines, especially in HL-60 cells, were down-regulated by ATRA.

Objective To quantitatively analyze the impact of environmental hygiene on the occurrence of health-care-associated infections(HAI).Methods Monitoring data of HAI and environmental hygiene from a tertiary first-class hospital from January 2018 to December 2022 were collected,and the impact of environmental bacterial colony forming unit(CFU)on the occurrence of HAI was analyzed by a time-series generalized additive model.Results The single-contamination model showed a significant positive correlation between HAI and staff's hand bacterial CFU(β1=0.009,P=0.012).For an increase of 1 interquartile range(IQR)in the monthly mean CFU per dish(MCFU/Dish)of staffs'hand,the incidence of HAI increased by 13.28％(95％CI:2.82％-24.81％).Subgroup and lag effect analysis showed that when the monthly MCFU/Dish(after hand disinfection)of staffs'hand in-creased by one IQR,the excess risk(ER)of HAI for the month(lag0)was 16.26％(95％CI:15.45％-17.09％).In the multi-contamination model,the correlation between surface contamination and HAI was also statistically sig-nificant.Conclusion There is a significant correlation between hospital environmental hygiene and the occurrence of HAI.

OBJECTIVETo study the therapeutic effect of Weicao Capsule (WCC) on gout.

METHODSTwo hundred gout patients were assigned to two groups. The treated group was treated with WCC and the control group was treated with Tongfengding Capsule. Both groups were given the respective treatments orally 3 times a day, 2 capsules each time with 2 weeks as one course and all patients received 2 successive courses of treatment. Changes of blood beta(2)-microglobulin (beta(2)-M), hemoglobin (Hb), 24 h urinary protein (24 h UP), pH value of urine and blood uric acid (BUA) as well as kidney function were observed.

RESULTSAfter treatment, level of beta(2)-M got lowered significantly, Hb and 24 h UP, blood urea nitrogen, serum creatinine and the clearance rate of creatinine, as well as blood lipids all improved obviously in the treated group (all P<0.01), while these parameters remained unchanged in the control group (P>0.05). The pH value of urine was improved in both groups showing an insignificant difference between them (P>0.05). BUA was decreased in both groups with a decrease to a larger extent in the treated group (P<0.01). The total effective rate was 87% in the treated group, which was superior to that in the control group (62%, P<0.05).

CONCLUSIONWCC has a favorable therapeutic effect on gout and its mechanism of action for improving renal function and reducing urinary protein could be related with the lowering of blood beta(2)-M, BUA and lipids.

This study was aimed to investigate the expression of cdx2 gene in pediatric patients with acute leukemia and its clinical implication. The bone marrow and peripheral blood were collected from 33 newly diagnosed pediatric patients with acute leukemia, the cdx2 gene expression in each AL subtypes and normal controls was detected by RT-PCR, the relationship between cdx2 expression and response to treatment was observed. The results showed that the expression of cdx2 was positive in 25 out of 30 AL cases (83.3%), to be exact, in 20 of 21 ALL cases (95.2%) and in 5 of 9 AML cases (55.6%), which showed statistical difference (p < 0.05). The cdx2 mRNA could be detected also in 1 of 3 CML cases. However, no expression of cdx2 was observed in all normal control which revealed significant difference between patient group and normal control group. 21 AL patients with cdx2 positive expression (17 ALL and 4 AML patients) and 4 AL patients with cxd2 negative expression (1 ALL and 3 AML patients) all reached complete remission (CR) after treatment, which showed no correlation with CR rate. 8 patients with positive cdx2 expression were followed up. As a result, the cdx2 positive expression at initial diagnosis of patients remained positive at reaching CR, but it gradually turned to negative along with prolonging of CR, while the cdx2 negative expression at initial diagnosis of patients remained negative at CR in bone marrow level. It is concluded that cdx2 positive expression is observed in the majority of pediatric AL patients, even positive rate in ALL patients is higher than that in AML patients, while the cdx2 expression also can be observed in CML patients. The cdx2 positive expression is not related to the CR rate in AL patients.

To explore the effects of crude toxins from Colletotrichum gloeosporioides(C. gloeosporioides)on the growth of Dendrobium officinale Kimura et Migo(D. officinale),and to provide early basis for thescreening and cultivation of the resistant variants of C. gloeosporioides. Methods Seedlings of D. officinal werecultivated in MS medium added with different concentrations of the crude toxins from C. gloeosporioides. Theeffects of the crude toxin on the growth of seedlings were observed, and the optimum resistance -selectionthreshold was preliminarily screened. Results In the concentration range of 5％ - 15％(volume fraction),crudetoxins from C. gloeosporioides increased the plant height,stem diameter,number of new bud,root number,and fresh mass of D. officinale,among which the effect of 5％(volume fraction)of crude toxins was the moststrongest. In the concentration range of 35％ - 40％(volume fraction),crude toxins suppressed the plant height,leaf number,number of new bud,root number,and the fresh mass of D. officinale. When cultured with 20％(volume fraction)crude toxins, D. officinale was blooming, and the flowers appeared variation phenomenon.Conclusion The crude toxins from C. gloeosporioides have biological activity and certain toxicity,which can beconsidered as a selection agent instead of pathogenin in vitro to screen the resistant variant of D. officinale,butthe optimum resistance-selection threshold still needs further research.

To estimate the effect of ligustrazine on the expression of PECAM-1/CD31 and hematopoietic reconstitution in syngenic bone marrow transplanted mice, 56 BALB/c mice were divided into 3 groups: normal control group, BMT control group, ligustrazine treated group (BMT + Ligustrazine) and syngenic BMT mouse models were established according to the literatures. The BMT control group and the ligustrazine treated group were given orally 0.2 ml saline and 2 mg ligustrazine twice a day respectively. On days 7, 14, 21 after BMT, mice were killed and peripheral blood cells, bone marrow nucleated cells (BMNC) were detected. Histological observation of bone marrow was made and the CD31 expression was assayed by flow cytometry. The results showed that in ligustrazine treated group the peripheral blood cell, BMNC counts on days 7, 14, 21 after BMT were higher than in the BMT control group (P < 0.01 or P < 0.05). The expression of CD31 in ligustrazine treated group on days 7, 14, 21 after BMT was also higher than in the BMT control group (P < 0.01 or P < 0.05). In conclusion, ligustrazine enhances CD31 expression in bone marrow cells after syngenic bone marrow transplantation of mice, which may be related to the mechanisms underlying the ligustrazine accelerating hematopoietic reconstitution in syngeneic bone marrow transplantation.
