Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases, which as a group can degrade essentially all extracellular matrix components. The proteolytic property of the MMPs is important during wound healing to remove debris and facilitate cell migration. Targeting towards the decreased MMPs activities is a new treatment strategy for healing chronic wounds. Salvia miltiorrhiza is a popular Chinese herb that could promote chronic ulcers healing for topical use. Salvianolic acid B (Sal B) is the most abundant bioactive component in Salvia miltiorrhiza. The research was designed to explore the inhibitory effects of Sal B on MMP-1, MMP-2 and MMP-9 activities.

Objective To investigate the clinical and laboratory features of acute promyelocytic leukemia (APL).Methotis 513 APL patients in the last two decades were retrospectively analyzed in this research.We investigated the clinical features including age,sex,abnormality of peripheral hemogram before treatment.therapeutic effect and follow-up and laboratory data such as morphology,immunology,cytogenetics and molecular biology(MICM).Results The median age of the APL patients was 33 years old and the ratio of male and female was 1.21:1.Before treatment,the median level of WBC was 4.3×109/L and the deteetion rate of abnormal promyelocyte on blood film was 85.8%;with immunophenotypie detection,the expression levels of CD117、CD34、HLA-DR、CD7、CD14 and CD19 in APL were found to be lower and the expression 1evels of CD2、CD33 and MPO higher than those in other subtypes of acute myelocytie leukemia(AML)(beth P<0.01).Specific abnormal chromosome t(15;17)was detected in 91.7%of the patients,of whom 75.9%had standard translocation of t(15;17),being the most common one and 15.8% of the patients had t(15;17)with additional abnormal chromosome.There was only 7.5%of the patients with nolnlal karyotype.However,the presence of both simple translocation and complex translocation was seldom seen.With molecular biological detection.PML/RARα fusion gene positive rate was 99.6%.In a relativelv long clinical follow-up,we found that the complete remission(CR)rate in APL patients was 84.7%.incidence of DIC was 13.4%and five-year survival rate was 30.7%.111e median count of WBC in CR group was lower than that non-remission group(P<0.01).There were no significant differences on expressions of CD34 and CD2 and changes of cytogenetics between the two groups(P>0.05).Conclusions Comprehensive evaluation of MICM could be of important significance in the diagnosis and prognosis iudgrnent for APL patients.The CR rate in these patients with high WBC eount was considerable low.

Objective To determine the half-effective target effect-site concentration (Ce) (EC50) of sufentanil required to inhibit the body movement during insertion of ureteroscopes when combined with propofol in patients undergoing transureteroscopic holmium laser lithotripsy. Methods Fifty ASA Ⅰ or Ⅱ patients of both sexes, aged 20-60 yr, BMI ＜ 30 kg/m2 , undergoing transureteroscopic holmium laser lithotripsy were randomly divided into 5 groups according to the different C es of sufentanil ( n = 10 each): group S1 (Ce 0.21 ng/ml), group S2(Ce 0.14 ng/ml), group S3(Ce 0.09 ng/ml), group S4(Ce 0.06 ng/ml), group S5(Ce 0.04 ng/ml). TCI of propofol with target plasma concentration set at 2.5-3.0 μg/ml was given. Sufentanil with the corresponding Ce was infused in each group. The ureteroscopes were inserted as soon as the patients lost consciousness and the effect-site concentration of sunfentanil was achieved. The response was defined as positive when body movement occurred within 1 min after insertion of ureteroscopes. The EC50 of sufentanil required to inhibit the body movement during insertion of ureteroscopes when combined with propofol and 95% confidence interval (CI) were calculated. Results The EC50 of sufentanil required to inhibit the body movement during insertion of ureteroscopes when combined with propofol was 0.084 ng/ml and 95% CI was 0.066-0.107 ng/ml. Conclusion The EC50 of sufentanil required to inhibit the body movement during insertion of ureteroscopes was 0.084 ng/ml when combined with propofol.

AIM: To evaluate the effects of acetyl-11-keto-beta-boswellic acid (AKBA, a main active component from frankincense, one of the traditional Chinese herb for healing wounds) on the activities of matrix metalloproteinase(MMP)-1, MMP-2 and MMP-9.METHODS: Pure human interstitial collagenase (MMP-1) or gelatinase A (MMP-2) was activated by p-aminophenylmercuric acetate (APMA), and was incubated with AKBA for 1 h. The activities of the enzymes were observed by quenched fluorescent substrate. The lysates of rat polymorphonuclear neutrophils [PMNs, rich in gelatinase B (MMP-9)] was incubated with AKBA for 1 h, and activity of MMP-9 was tested by gelatin zymography. Three cell models: activated human dermal fibroblasts by TNF-α, activated THP-1 cells by PMA and fibroblasts-THP-1 co-culture system were established. AKBA was cultured with these cell models for 24 h. The levels of MMP-1, MMP-2 and MMP-9 in the cell culture supernatants were tested by ELISA and activities of MMP-2 and MMP-9 were tested by gelatin zymography assays.RESULTS: AKBA dose-dependently inhibited the activities of human MMP-1 and MMP-2 at the range of 0.1-0.8 mmol/L, with 50% inhibitory concentration (IC50) of 0.18 mmol /L and 0.27 mmol/L, respectively. In the range of 0.05-0.85 mmol/L, AKBA inhibited the MMP-9 activity (P<0.01). Although AKBA promoted fibroblasts to secrete MMP-2, the production of MMP-9 by THP-1 was inhibited. In the cell co-culture system, the inhibitory effects on MMP-1, MMP-2 and MMP-9 productions were also observed.CONCLUSION: AKBA, as a bioactive component of frankincense, has an inhibitory effect on MMPs production and activities, indicating the possible mechanism for healing chronic wounds by frankincense.

AIM:Cinnamyl aldehyde (CA) is one alcohol ingredient derived from Cinnamomum cassia,which is widely used in treating chronic skin wound in Chinese medicine with the curative effect of ‘rescuing YANG’. The purpose of the present study was to investigate the expression of c-Fos, c-Myc proteins at different time points in NIH3T3 treated with CA and explore the possible mechanism of promoting cell proliferation by CA. METHODS: MTT assay was used for observing cell proliferation. Expression of c-Fos and c-Myc proteins in NIH3T3 cells were assessed by immunocytochemistry assay. RESULTS: The cell proliferation was promoted obviously when CA concentration was between 8.8?10-2 ?g/L and 8.8?10 ?g/L. CA at concentration of 5.5 ?g/L significantly induced expression of c-Fos, c-Myc proteins at 2-3 h after the stimulation compared with control group (P

Objective:To investigate the clinical effects of chidamide combined with linperlisib in treatment of recurrent angioimmunoblastic T-cell lymphoma (AITL) after autologous stem cell transplantation (ASCT).Methods:The clinical data of 1 patient with recurrent AITL receiving treatment of chidamide combined with linperlisib after ASCT in Sun Yat-Sen University Cancer Center in March, 2021 were retrospectively analyzed, and the related literatures were reviewed.Results:The 55- year-old male patient was presented with fatigue, night sweats and emaciation. According to the results of pathology, immunohistochemistry and imaging after admission, this patient was diagnosed as AITL. After treatment with venbutuximab + CDP (cyclophosphamide + doxorubicin + prednisone) regimen, the patient achieved complete remission, and then ASCT was performed. After the transplatation, programmed death receptor 1 inhibitor was maintained for 4 courses of treatment. It recurred 16 months after ASCT, and the patient achieved partial remission after 1 course of chidamide combined with linperlisib, and achieved complete remission after 2 courses of treatment. Later, recheck of hepatitis B virus showed a quantitative increase after the self withdrawal of anti hepatitis B drugs, and then the primary treatment was suspended. The last follow-up time was March, 2024, and recheck results of whole body enhanced magnetic resonance imaging indicated recurrence.Conclusions:The combination of chidamide and linperlisib is effective and safe in treatment of recurrent ATIL after ASCT.
