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.

Objective:To evaluate the immunogenicity and immune persistence of purified Vero cells rabies vaccine (PVRV) with Zagreb and Essen regimen.Methods:Prospective study: Patients with first Class II exposure to rabies were recruited from the Dog Injury Cinic of Guangxi Center for Disease Control and Prevention (Guangxi CDC) and randomly divided into the Zagreb (2-1-1) and Essen (1-1-1-1-1) regimen group. All patients were inoculated with the vaccines from the same manufacturer and batch, and 3 ml serum was collected at the 45th day and in 1-year, 2-year and 3-year after immunization. Rapid fluorescent inhibition test (RFFIT) was used to detect rabies virus neutralizing antibody (RVNA). The attenuation of RVNA positive rate and geometric mean titer (GMT) with time was analyzed. Retrospective study: The informed consents for rabies vaccine in the Dog Injury Clinic of Guangxi CDC were checked out. The patients who were injected with PVRV (same manufacturer but unlimited batch) but without passive immune agents for the first time within 3 years were selected and divided into 1-year, 2-year and 3-year group. Each group was further divided into Zagreb and Essen regimen group. The serum (3 ml) was collected at 1 year, 2 years and 3 years after immunization and detected the RVNA by RFFIT.Results:Prospective study: The RVNA positive rates on the 45th day and in 1-year, 2-year and 3-year after immunizationin in the Zagreb and Essen regimen group were 100%, 95%, 85%, 80% and 98.25%, 89.47%, 89.47%, 85.96%, respectively. There was no statistically significant difference in the RVNA positive rates at the same time point between the two regimen groups ( P>0.05). The RVNA GMT on the 45th day and in 1-year, 2-year, and 3-year in the Zagreb and Essen regimen group were 11.32 IU/ml, 1.69 IU/ml, 1.30 IU/ml, 1.30 IU/m and 13.18 IU/ml, 2.13 IU/ml, 1.87 IU/ml, 1.84 IU/m, respectively. There was no significant difference in the RVNA GMT levels at the same time point between the two regimen groups ( F=1.971, P=0.164). The RVNA GMT levels in the two regimen groups had the same trend of attenuation over time (time*group F=0.702, P=0.435). Retrospective study: The RVNA positive rates in 1-year, 2-year and 3-year after immunization in the Zagreb and Essen regimen group were 100%, 95%, 91.43%和94.73%, 86.21%, 87.5%, respectively. There was no statistically significant difference in the RVNA positive rates at the same time point between the two regimen groups ( P>0.05). The RVNA GMT in 1-year, 2-year, and 3-year groups after immunization in the Zagreb and Essen regimen group were 2.65 IU/ml, 2.03 IU/ml, 1.57 IU/ml和3.2 IU/ml, 2.58 IU/ml, 2.45 IU/ml, respectively. There was no significant difference in the RVNA GMT levels at the same time point between the two regimen groups ( P>0.05). Conclusions:The PVRV showed the same excellent immunogenicity and immune persistence after the vaccination with the Zagreb and Essen regimens.

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.

OBJECTIVETo explore the protective effects of rhubarb aglycone combined with urokinase (UK) thrombolysis on brain microvascular basement membrane impairment in rats with thrombus-occluded cerebral ischemia by regulating the expression of IgG, CoLIV and LN in rats brain, by which the level of injury of brain microvascular basement membrane could be detected.

METHODRats were randomly divided into sham-operated, model, thrombolysis, rhubarb aglycone and combination (rhubarb aglycone combined with thrombolysis) groups. Moreover, rats in model, thrombolysis, rhubarb aglycone and combination groups were randomly divided into 3, 6, and 9 h groups respectively. Model of thrombus-occluded cerebral ischemia was duplicated by using the combination of rats' auto-thrombus with inserting the nylon thread. Rats were administrated with thrombolysis therapy through artery at 3, 6, and 9 h after cerebral ischemia. At 24 h of administration through artery, intracranial hemorrhage ratio (ICHR) and mortality of rats were observed, and then the brain of rats was taken. In the study, expression of IgG, CoLIV and LN in rats brain were measured.

RESULTThrombolysis at 9 h of cerebral ischemia made rats mortality and BHR increase, administration of combined therapy could make them decrease. Expression of IgG level in rats brain of 9 h and 6 h model groups increased, while CoLIV and LN expression decreased significantly. In each administration 9 h group, IgG level was lower, and CoLIV and LN were higher, such changes appeared significantly in rhubarb aglycone and association groups.

CONCLUSIONBrain microvascular basement membrane impairment could be caused by the therapy of delayed thrombolysis, which made the mortality and BHR increase. Rhubarb aglycone combined with the therapy of thrombolysis could perform the protective effects on brain microvascular basement membrane and then decrease the ICHR and mortality caused by thrombolysis after cerebral ischemia.

In order to reveal the treatment mechanism of Chinese medicine with the effect of activating blood and resolving putridity, we selected acetyl-11-keto-beta-boswellic acid (AKBA) and arsenic trioxide (ATO), the main monomeric components of frankincense and arsenolite which are two most commonly used Chinese medicine with effect of activating blood and resolving putridity. We combined AKBA and ATO as a compound, and explored its regulatory role in productions and activities of matrix metalloproteinase (MMP)-1, MMP-2 and MMP-9 in human skin fibroblasts (HSFbs) and human acute monocytic leukemia cell line THP-1 in inflammatory state.

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.

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.

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.
