ABSTRACT

Objective: Total neoadjuvant therapy has been used to improve tumor responses and prevent distant metastases in patients with locally advanced rectal cancer (LARC). Patients with complete clinical responses (cCR) then have the option of choosing a watch and wait (W&W) strategy and organ preservation. It has recently been shown that hypofractionated radiotherapy has better synergistic effects with PD-1/PD-L1 inhibitors than does conventionally fractionated radiotherapy, increasing the sensitivity of microsatellite stable (MSS) colorectal cancer to immunotherapy. Thus, in this trial we aimed to determine whether total neoadjuvant therapy comprising short-course radiotherapy (SCRT) combined with a PD-1 inhibitor improves the degree of tumor regression in patients with LARC. Methods: TORCH is a prospective, multicenter, randomized, phase II trial (TORCH Registration No. NCT04518280). Patients with LARC (T3-4/N+M0, distance from anus ≤10 cm) are eligible and are randomly assigned to consolidation or induction arms. Those in the consolidation arm receive SCRT (25Gy/5 Fx), followed by six cycles of toripalimab plus capecitabine and oxaliplatin (ToriCAPOX). Those in the induction arm receive two cycles of ToriCAPOX, then undergo SCRT, followed by four cycles of ToriCAPOX. Patients in both groups undergo total mesorectal excision (TME) or can choose a W&W strategy if cCR has been achieved. The primary endpoint is the complete response rate (CR, pathological complete response [pCR] plus continuous cCR for more than 1 year). The secondary endpoints include rates of Grade 3-4 acute adverse effects (AEs) etc. Results: Up to 30 September 2022, 62 patients attending our center were enrolled (Consolidation arm: 34, Induction arm:28). Their median age was 53 (27-69) years. Fifty-nine of them had MSS/pMMR type cancer (95.2%), and only three MSI-H/dMMR. Additionally, 55 patients (88.7%) had Stage III disease. The following important characteristics were distributed as follows: lower location (≤5 cm from anus, 48/62, 77.4%), deeper invasion by primary lesion (cT4 7/62, 11.3%; mesorectal fascia involved 17/62, 27.4%), and high risk of distant metastasis (cN2 26/62, 41.9%; EMVI+ 11/62, 17.7%). All 62 patients completed the SCRT and at least five cycles of ToriCAPOX, 52/62 (83.9%) completing six cycles of ToriCAPOX. Finally, 29 patients achieved cCR (46.8%, 29/62), 18 of whom decided to adopt a W&W strategy. TME was performed on 32 patients. Pathological examination showed 18 had achieved pCR, four TRG 1, and 10 TRG 2-3. The three patients with MSI-H disease all achieved cCR. One of these patients was found to have pCR after surgery whereas the other two adopted a W&W strategy. Thus, the pCR and CR rates were 56.2% (18/32) and 58.1% (36/62), respectively. The TRG 0-1 rate was 68.8% (22/32). The most common non-hematologic AEs were poor appetite (49/60, 81.7%), numbness (49/60, 81.7%), nausea (47/60, 78.3%) and asthenia (43/60, 71.7%); two patients did not complete this survey. The most common hematologic AEs were thrombocytopenia (48/62, 77.4%), anemia (47/62, 75.8%), leukopenia/neutropenia (44/62, 71.0%) and high transaminase (39/62, 62.9%). The main Grade III-IV AE was thrombocytopenia (22/62, 35.5%), with three patients (3/62, 4.8%) having Grade IV thrombocytopenia. No Grade V AEs were noted. Conclusions: SCRT-based total neoadjuvant therapy combined with toripalimab can achieve a surprisingly good CR rate in patients with LARC and thus has the potential to offer new treatment options for organ preservation in patients with MSS and lower-location rectal cancer. Meanwhile, the preliminary findings of a single center show good tolerability, the main Grade III-IV AE being thrombocytopenia. The significant efficacy and long-term prognostic benefit need to be determined by further follow-up.

ABSTRACT

Objective: To examine the clinical characteristics and prognostic factors of elderly patients with mantle cell lymphoma (MCL) and the impact of nutrition and underlying diseases on the prognosis of elderly patients with MCL. Methods: retrospectively analyzed 255 elderly patients with MCL from 11 medical centers, including Peking University Third Hospital between January 2000 and February 2021. We analyzed clinical data, such as age, gender, Mantle Cell Lymphoma International Prognostic Index score, and treatment options, and performed univariate and multivariate prognostic analysis. We performed a comprehensive geriatric assessment on elderly MCL patients with medical records that included retraceable underlying disease and albumin levels, and we investigated the impact of basic nutrition and underlying disorders on MCL prognosis in the elderly. Results: There were 255 senior individuals among the 795 MCL patients. Elderly MCL was more common in males (78.4%), with a median age of 69 yr (ages 65-88), and the majority (88.6%) were identified at a late stage. The 3-yr overall survival (OS) rate was 42.0%, with a 21.2% progression-free survival (PFS) rate. The overall response rate (ORR) was 77.3%, with a 33.3% total remission rate. Elderly patients were more likely than younger patients to have persistent underlying illnesses, such as hypertension. Multivariate analysis revealed that variables related with poor PFS included age of ≥80 (P=0.021), Ann Arbor stage Ⅲ-Ⅳ (P=0.003), high LDH level (P=0.003), involvement of bone marrow (P=0.014). Age of ≥80 (P=0.001) and a high LDH level (P=0.003) were risk factors for OS. The complete geriatric assessment revealed that renal deficiency was associated with poorer OS (P=0.047) . Conclusions: Elderly MCL patients had greater comorbidities. Age, LDH, renal function, bone marrow involvement, and Ann Arbor stage are all independent risk factors for MCL in the elderly.

ABSTRACT

Objective: This study aimed to see how different initial treatment regimens affected the long-term prognosis of patients with extranodal marginal zone mucosa-associated lymphoid tissue lymphoma confining to the ocular adnexal (OAML) . Methods: Between April 2008 and April 2019, 109 patients with initial mucosa-associated lymphoid tissue confining to ocular adnexal were evaluated and followed-up, and the prognosis of various initial treatment regimens were examined. Results: A total of 36 patients underwent complete surgical resection of the lesions, and 73 patients had residual lesions after surgery, of which 37 patients chose watchful waiting, and 36 patients chose treatment. The treatment regimen included local radiotherapy and systemic treatment (chemotherapy, immunochemotherapy, the combination of radiotherapy and chemotherapy, etc.) , and no serious toxic and side effects were observed in patients receiving systemic treatment. The median follow-up time was 61 (10-142) months. The 5-year and 10-year progression-free survival (PFS) of monocular involvement patients were 78.2% and 76.0% . The 5-year and 10-year PFS rates of patients with binocular involvement were 64.4% and 23.5%. There was significant diference in PFS between patients with monocular and binocular involvement (P=0.010) . Patients who received additional treatment had higher PFS than those patients in the watchful waiting group (P=0.046) . The 5-year PFS was 71.4% and 90.1% among patients in the watchful waiting group and those who received additional treatment, whereas the 10-year PFS was 63.5% and 75.1% , respectively. Patients with OAML were still a risk of disease progression after 5 years. Conclusions: Patients with binocular involvement OAML at the start of the disease had a poor prognosis, but treatment could reduce the risk of recurrence/progression. Systemic therapy is one of the first-line treatment options for patients with OAML, who require long-term monitoring.

ABSTRACT

@#In recent years, the application of artificial intelligence(AI)has been greatly promoted in medical care, especially in the field of image recognition which has played an irreplaceable role in the diagnosis of ophthalmic diseases. AI has made remarkable achievements in the diagnosis and treatment of anterior segment diseases such as classification of infectious keratitis, screening of keratoconus, grading of lens opacity, automatic staging of cataract surgery videos, prediction of postoperative refraction status, and the diagnosis of primary angle-closure glaucoma. It is promising that AI could help solve many clinical problems and realize early diagnosis and treatment of diseases. However, there are still some challenges such as the ambiguity of black-box process, the absence of public data sets and the complexity of algorithms. In this paper, the current studies of AI applications in anterior segment diseases have been reviewed in detail. Also, the challenges and future directions of AI in ophthalmology have been proposed.

ABSTRACT

Network Meta-analysis was used to evaluate the efficacy and safety of different oral Chinese patent medicines combined with transcatheter arterial chemoembolization(TACE) in the treatment of primary liver cancer. Randomized controlled trials of oral Chinese patent medicines for primary liver cancer were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library and EMbase databases from inception to May 2020. According to the Cochrane recommendation standard, the quality of the included articles was evaluated, and the data were analyzed by RevMan, R software and GeMTC software. A total of 10 kinds of oral Chinese patent medicines and 68 RCTs were included. Network Meta-analysis results showed that: as compared with TACE alone, 10 kinds of oral Chinese patent medicines combined with TACE showed advantages in effective rate, 1-year survival rate, 2-year survival rate, KPS score improvement rate and reduced adverse reaction incidence. In the pairwise comparison of oral Chinese patent medicines, the results showed that Cidan Capsules were superior to Jinlong Capsules and Xihuang Pills in 1-year survival rate. According to the probabi-lity ranking results: Shenyi Capsules and Ganfule were more obvious in improving the effective rate; Cidan Capsules and Shenyi Capsules were more effective in improving the 1-year survival rate; Pingxiao Capsules and Shenyi Capsules had better efficacy in improving 2-year survival rate; Huaier Granules and Shenyi Capsules had better efficacy in improving the quality of life; Huisheng Oral Liquid and Ganfule were more effective in reducing the incidence of adverse reactions(such as nausea, vomiting and leukocytosis). The current evidence showed that oral Chinese patent medicine combined with TACE was superior to TACE alone in efficacy and safety. In terms of the effective rate, 1-year survival rate, 2-year survival rate, KPS score improvement rate and reduced adverse reaction incidence, the optimal treatment measures were Shenyi Capsules, Cidan Capsules, Pingxiao Capsules, Huaier Granules and Huisheng Oral Liquid in turn. However, due to the limitations of the research, the current level of evidence is not high, and clear conclusions and evi-dence strength still need to be further verified and improved by high-quality researches.

ABSTRACT

To systematically evaluate the efficacy and safety of Huaier Granules in the adjuvant treatment of primary liver cancer. The databases of CNKI, Wanfang, VIP, CBMdisc, PubMed, Cochrane Library and EMbase were searched by computer to screen out the randomized controlled trial on Huaier Granules combined with Western medicine in the treatment of primary liver cancer from the establishment of the databases to January 2020. Data extraction and quality evaluation were conducted for the included literature. Meta-analysis was conducted with RevMan 5.3 software, and evidence quality evaluation was conducted for the outcomes by GRADE profiler software. A total of 24 articles were included, with a total sample size of 2 664 cases. Meta-analysis showed that as compared with Western medicine alone, Huaier Granules combined with Western medicine could improve the objective remission rate(RR=1.38, 95%CI[1.26, 1.51], P<0.000 01), disease control rate(RR=1.29, 95%CI[1.10, 1.52], P=0.002) and 6-month survival rate(RR=1.20, 95%CI[1.10, 1.32], P<0.000 1), 1-year survival rate(RR=1.39, 95%CI[1.23, 1.58], P<0.000 01), 2-year survival rate(RR=1.95, 95%CI[1.28, 2.96], P=0.002), KPS score(MD=17.15, 95%CI[6.47, 27.83], P=0.002) and the improvement rate of KPS score(RR=2.02, 95%CI[1.47, 2.77], P<0.000 1), AFP decline rate(RR=1.40, 95%CI[1.20, 1.62], P<0.000 1), CD3~+(MD=17.34, 95%CI[9.28, 25.40], P<0.000 1), CD4~+(MD=8.62, 95%CI[1.59, 15.64], P=0.02), CD8~+(MD=1.95, 95%CI[-3.93, 7.82], P=0.52), CD4~+/CD8~+(MD=0.42, 95%CI[-0.33, 1.17], P=0.27); reduce the level of AFP(MD=-71.57, 95%CI[-80.42,-62.72], P<0.000 01), recurrence rate(RR=0.76, 95%CI[0.67, 0.85], P<0.000 01), and incidence of adverse reactions(RR=0.60, 95%CI[0.41, 0.89], P=0.01) in patients with primary liver cancer. According to the GRADE system, the evidence for outcome measures was low to very low. The results show that Huaier Granules have certain efficacy and high safety in adjuvant treatment of primary liver cancer, but its effect in reducing adverse reactions and improve immunity remains to be verified. Due to the poor quality of the included studies and evidences, the conclusions still need to be further verified by multi-center, large sample, and randomized double-blind controlled studies.

ABSTRACT

Thalidomide and its derivatives have been used in the treatment of myelodysplastic syndrome (MDS) because of their anti-angiogenic and immunomodulatory effects. In recent years, some studies have found that thalidomide and its derivatives not only showed significant efficacy in lower-risk MDS patients with del (5q), but also showed advantages in non-del (5q) MDS patients. In addition, the discovery of its molecular targets and new substrates makes it possible to develop a new generation of immunomodulatory drugs (IMiDs) and to design IMiDs-based proteolysis-targeting chimeras. In this review, the new progress in mechanism and clinical application of thalidomide and its derivatives were summarized briefly, so as to provide a more scientific, reasonable and effective scheme to the treatment of MDS.

ABSTRACT

OBJECTIVE: To study the chemical constituents and analgesic activity of the aerial parts of Skimmia multinervia. METHODS: The chemical constituents were isolated by column chromatography packed with MCI and silica gel, respectively, and the structures of the purified compounds were elucidated by NMR and MS analysis. The analgesic activities of the extract, fractions and selected compounds from the aerial parts of S. multinervia were evaluated by using acetic acid-induced writhing test in mice model. RESULTS: The structures of compounds 1-13 are identified as skimmin (1), imperatorin (2), auraptene (3), umbelliferon (4), scopoletin (5), limonin (6), limonexic acid (7), nomilin (8), citrusin (9), taraxerol (10), kanalpin (11), skimmianine (12), and methyl vanillate (13). The extract, ethyl acetate fraction, and alkaloid fraction could reduce the times of mice writhing induced by acetic acid, and the analgesic effect of compound 3, with inhibition rate of 88.18%, was much better than that of the positive control, aspirin. CONCLUSION: Compounds 1-13 are isolated from the plant for the first time, while 7, 9, 11, and 13 are firstly isolated from Skimmia genus. The analgesic activities of S. multinervia and compound 3 are reported for the first time.

ABSTRACT

Background@#Extranodal natural killer/T-cell lymphoma (ENKTL), nasal type, is an aggressive entity within the World Health Organization classification of lymphoid tumors. The International Prognostic Index is reported to be prognostically meaningful for ENKTL, but lacks discriminatory power for stage I/II ENKTL with extensive local invasion. This study aimed to evaluate the prognostic effects of local invasion by site and tissue type in patients with ENKTL.@*Methods@#We retrospectively analyzed data of 86 patients who were diagnosed with ENKTL by the Department of Pathology of Beijing Tongren Hospital from June 2002 to April 2016, and ascertained tumor infiltration of adjacent structures (AS), bone, and soft tissue for each patient, using physical findings and imaging scans. We used univariate and multivariate analysis to assess the association of each involved tissue or site with patients’ overall survival (OS).@*Results@#Of the 86 patients, 71(82.6%) experienced invasion of AS, 22(25.6%) of soft tissue, and 26(30.2%) had bone involvement. Overall, patients with AS involvement did not show significantly shorter survival than those without AS involvement (Log rank χ2 = 1.177, P = 0.278); however, patients who had involved eyeballs or brains showed significantly lower 2-year OS rates than those without eyeball involvement (Log rank χ2 = 4.105, P = 0.043) or brain involvement (Log rank χ2 = 7.126, P = 0.008). Patients with involved local soft tissue or bones, respectively, showed lower 2-year OS rates than those without involved local soft tissue (Log rank χ2 = 10.390, P = 0.001) or bones (Log rank χ2 = 8.993, P = 0.003). Multivariate analysis showed that involvement of the cheek or facial muscles (hazard ratio, HR = 5.471, 95% confidence interval [CI]: 1.466–20.416, P = 0.011) and the maxilla bone (HR = 6.120, 95% CI: 1.517–24.694, P = 0.011) were significantly independent predictors of lower 2-year OS rates.@*Conclusions@#Imaging can accurately detect ENKTL invasion of AS, soft tissue, and bone. Involvement of local soft tissue or bone was significantly associated with lower 2-year OS rates. Involvements of the cheek or facial muscle, as well as maxilla bone, are independent predictors of lower 2-year OS rates in ENKTL patients.

ABSTRACT

Objective To investigate the relationship between albumin/globulin ratio (AGR) and postoperative survival among patients with esophageal squamous cell carcinoma(ESCC) undergoing radical oesophagectomy, to establish an effective prognostic nomogram for ESCC and to provide a reference for prognosis prediction of ESCC. Methods From February 2014 to September 2017, 390 ESCC patients who underwent surgery were retrospectively enrolled from the tumor hospital in Fujian Province. The receiver operating characteristic curves(ROC) were applied to establish optimal cutoff points. Chi-square test was used to estimate the relationship between the AGR and the clinical features. Cox proportional hazards model was used to estimate the HR and 95% CI for the associations between AGR and Prognosis of ESCC patients. A nomogram model was established to predict the outcome of ESCC patients. Results The ROC demonstrated the best cutoff value for AGR was 1.16. A total of 356 patients were recruited in the final analysis, who were divided into the high AGR group (≥1.16) and the low AGR group (<1.16) by the best cutoff value. Both 1-year and 3-year survival rates in the high AGR group were higher than those detected in the low AGR group(all P<0.05). Multivariate analysis showed that the T stage, N stage, and AGR were independent prognostic factors of overall survival(all P<0.05). The HR of T stage was 1.87 (T3-T4 vs T1-T2, 95% CI: 1.04-3.35); The HR of N stage was1.89 (N+ vs N0, 95% CI: 1.13-3.17); The HR of AGR was 0.57(the high AGR group vs the low AGR group, 95%CI: 0.36-0.90). The concordance index(C-index) of the nomogram to predict overall survival was 0.68 (95% CI: 0.62-0.73,P<0. 001).Conclusions The AGR was an independent prognosis factor for operated ESCC patients. The prognosis of ESCC in the high AGR group was better than that in the low AGR group and the prognostic nomogram provides individualized risk estimate of survival in ESCC patients after surgery.

ABSTRACT

Objective: To summarize the adverse effects of pegaspargase in the treatment of lymphoid malignancies and management experience. Methods: Clinical data of patients who received chemotherapy including pegaspargase in the Department of Hematology of Beijing Tongren hospital during August 2011 to December 2015 were retrospective analyzed, and the adverse effects of pegaspargase and the management experience was summarized. Results: A total of 129 patients with 443 times of pegaspargase used during this period. The common adverse reactions included allergic reactions in 2 cases (1.6%), acute pancreatitis in 19 (14.7%) including 6 acute symptomatic pancreatitis and 13 chemical pancreatitis with elevated pancreatin, hypertriglyceridemia in 15 cases(11.6%), hyperglycemia in 85 (65.9%), hypoglycemia in 7 (5.4%), elevated aminotransferase in 25 (19.4%), hyperbilirubinemia in 21 (15.5%), hypoalbuminemia in 62 (48.1%), prolonged APTT in 61 (47.3%), prolonged PT in 22 (17.1%), prolonged TT in 15 (11.6%), hypofibrinogen in 75 (58.1%), thrombus in 11 (8.5%) and bleeding in 3 (2.3%). The above adverse reactions were improved by symptomatic treatment of anti allergy, inhibition of secretion of pancreatic juice, lipid lowering, hypoglycemic, liver preservation, supplementation of plasma and hemostasis, respectively. Some serious adverse reactions affected the application of pegaspargase, even lead to discontinuation of the aspartate. Conclusion: Though adverse effects associated with pegaspargase are extensive, most patients can successfully complete the chemotherapy containing the pegaspargase with close monitoring and timely treatment.

ABSTRACT

To evaluate the clinical efficacy and safety of tripterygium glycosides (TG) in the treatment of henoch-schonlein purpura nephritis(HSPN). Seven English and Chinese databases (up to Nov. 9, 2017), were searched to collect the RCTs on TG for HSPN. Two researchers independently screened the literature according to inclusion criteria and exclusion criteria, extracted data, and evaluated the quality of the literature. After completion, cross-checking was performed and Meta-analysis was performed using RevMan 5.3 software. At the same time, different outcomes of the interventions were analyzed subgroupically. A total of 46 RCTs were included, with 1 659 in the experimental group and 1 596 in the control group. All the clinical studies showed a low quality. In terms of complete remission rate, the group with TG performed better than the group with conventional therapy or GC(RR=1.82,95%CI[1.39,2.39];RR=2.03,95%CI[1.37,2.99]),the group with TG+GC performed better than the group with GC(RR=1.46,95%CI[1.32,1.60]),and the group with CTX+GC performed better than the group with TG+GC(RR=0.35,95%CI[0.16,0.75]). In terms of total effective rate, the group with TG performed better than the group with conventional therapy or GC(RR=1.44,95%CI[1.19,1.74];RR=1.30,95%CI[1.16,1.46]),the group with TG+GC performed better than the group with GC(RR=1.27,95%CI[1.21,1.34]),and the group with CTX+GC performed better than the group with TG+GC(RR=0.60,95%CI[0.43,0.85]). No significant difference was found between the group with TG+GC and LEF+GC(RR=0.68,95%CI[0.30,1.53]). In terms of urinary protein, urine occult blood negative time,the group with TG performed better than the group with conventional therapy(MD=-9.00,95% CI[-11.99,-6.01];MD=-12.00,95%CI[-16.13,-7.87]),the group with TG+GC performed better than the group with GC(MD=-8.86,95%CI[-10.08,-7.64];MD=-16.24,95%CI[-23.80,-8.67]). In terms of recurrence rate, the group with TG+GC was lower than the group with GC(RR=0.13,95%CI[0.06,0.25]), but there were no significant difference between the group with TG and conventional therapy(RR=0.43,95%CI[0.15,1.19]). In adverse reactions, the common adverse effects of TG were gastrointestinal discomfort, liver damage and leucopenia. TG for the treatment of HSPN can improve clinical efficacy, reduce recurrence, and the adverse reactions are relatively safe. Due to the generally low methodological quality of the included studies, which affected the accuracy and reliability of the result. Therefore, more high-quality, large samples and multi-center randomized controlled trials are necessary for further evidence.

ABSTRACT

BACKGROUND: There is little information available in the mechanism of radiation-induced salivary gland injury, and its treatment and prevention are still at the exploratory stage.OBJECTIVE: To establish a rat model of radiation-induced xerostomia with 18 Gy electron beam and to observe the pathological changes of the submandibular gland and changes in saliva ingredients.METHODS: Totally 115 Wistar rats were randomly divided into exposure and control groups: the rats in the exposure group were subjected to anesthesia, and the submandibular gland received 18 Gy electron beam radiation to establish the model of radiation-induced xerostomia. The rats in the control group were only anesthetized but not exposed to radiation. The water intake was recorded at 21 dys after modeling. The saliva was collected and the submandibular gland was removed at 1, 3, 7, 14, 21, 28, 35 and 42 days to detect the saliva volume and submandibular gland index,and the morphological changes of the submandibular gland were observed by hematoxylin-eosin staining.RESULTS AND CONCLUSION: At 1-21 days after modeling, the average daily water intake was (6.42±1.91) mL in the exposure group and (4.82±1.20) mL in the control group, respectively (P < 0.05). During 42 days after modeling, the saliva secretion volume in the exposure group was lower than that in the control group, which was the lowest on day 7,and the difference was significant at 7, 21, 28 and 42 days after modeling between two groups (P < 0.05). The submandibular gland index in the exposure group was significantly lower than that in the control group at 1 and 21-42 days after modeling (P < 0.05). Hematoxylin-eosin staining results showed that in the exposure group, the rat submandibular gland appeared with inflammatory infiltration, glandular atrophy and karyopyknosis that were aggravated with time until day 42. To conclude, the rat model of radiation-induced xerostomia is established successfully with 18 Gy beam, characterized as increased water intake, decreased saliva volume and progressive aggravation of pathological injury of the submandibular gland.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the changes of hepcidin and ferropotin 1 expression in murine model of iron overload.</p><p><b>METHODS</b>The murine model of iron overload was established, C57BL/6 mice were injected with iron dextran intraperitoneally (10 mg) every 3 days for 4 weeks. Blood routine, serum ferritin and pathological sections were tested at the appointed time-point respectively (before iron injection, 2 weeks and 4 weeks after treatment of iron injection). The serum hepcidin was assayed by enzyme-linked immunosorbent method. The expression of ferroportin 1 in bone marrow cells was detected by RT-PCR and Western blot, respectively. The labile iron pool of bone marrow cells was measured by flow cytometry.</p><p><b>RESULTS</b>The absolute number and percentage of reticulocytes in the iron-overloaded mice were significantly decreased along with the increase of iron injection times (r=-0.938, r=-0.947), while no significant change was found in the number of white blood cells, hemoglobin level and platelet count. The level of serum ferritin was increased along with increase of iron injection time (r=0.894). Iron overload was found in pathological sections of different organs. Furthermore, serum hepcidin was increased along with increase of iron injection time (r=0.957). RT-PCR and Western blot analyses showed that the expressions of ferroportin 1 at mRNA and protein level were increased in the murine model of iron overload (P<0.05). Labile iron pool in bone marrow cells was also found to be increased in the murine model of iron overload(P<0.05).</p><p><b>CONCLUSION</b>The expressions of hepcidin and ferroportin 1 are increase in a murine model of iron overload, which may be contributed to the suppression effect on erythropoiesis in bone marrow.</p>

ABSTRACT

The aim of this study was to analyze the efficacy of first-line chemotherapy in treating patients with ocular adnexal extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT). Eight consecutive newly diagnosed ocular adnexal MALT lymphoma patients were treated with chemotherapy, in which 3 patients in stage IE were treated with a combination of cyclophosphamide, vincristine and prednisolone (COP) or cyclophosphamide, adriamycin, vincristine, and prednisolone (CHOP), 5 patients in stage IV were treated with COP/CHOP in combination with rituximab. The results showed that chemotherapy resulted in an overall response rate of 100%, 3 patients in stage IE were in partial remission (PR), 5 patients in stage IV were in complete remission (CR). After a median follow-up of 21 months, 3 patients in stage IE were still in PR status, 5 patients in stage IV were still in CR status, and no relapses or disease progression were observed. It is concluded that the first-line chemotherapy has been confirmed to be effective and well tolerated in patients with localized ocular adnexal MALT lymphoma. Rituximab combined with chemotherapy can increase remission rate, it is feasible option as first-line treatment for ocular adnexal MALT lymphoma.

ABSTRACT

In order to investigate the effect of anti-TGF-beta1 monoclonal antibody on the expansion of cord blood CD34(+) cells, the purified cord blood CD34(+) cells were divided into three groups: blank control group: purified cord blood CD34(+) cells cultured on day 0; control group: cells cultured for 3 days in the culture system, containing SCF, IL-3, IL-6 and FLT3-L; test group: cells cultured for 3 days in the same culture system as control group, but with anti-TGF-beta1 monoclonal antibody. The mononuclear cell counting (MNC), the expression of CD34 and c-kit, and CFU-GEMM, BFU-E and CFU-GM counting were detected in all three groups. The result showed that the expansion of MNCs, CD34(+) cells and CD34(+)c-kit(+) cells in test group [(2.35 +/- 0.25) x 10(5), (1.16 +/- 0.29) x 10(5), (1.09 +/- 0.26) x 10(5)] was significantly higher than that in control group [(1.25 +/- 0.13) x 10(5), (0.55 +/- 0.19) x 10(5), (0.51 +/- 0.2) x 10(5)](p < 0.01). The expansion of more primitive CD34(+)c-kit(-) subpopulation in test group [(12.95 +/- 3.17) x 10(3)] was even significantly higher than in control group (1.71 +/- 0.83) x 10(3) (p < 0.01). Colony forming assay showed that the number of earlier progenitor colony CFU-GEMM, BFU-E in test group [(16.3 +/- 4.72) x 10(3), (60.5 +/- 20.96) x 10(3)] was higher than that in control group [(5.0 +/- 2.58) x 10(3), (16.25 +/- 7.93) x 10(3)] (p < 0.01). The number of relatively mature CFU-GM between test group and control group was not statistical significance [(6.33 +/- 2.85) x 10(3) vs (4.0 +/- 2.28) x 10(3)](p > 0.05), but both were higher than that in blank group (0.75 +/- 0.29) x 10(3). These results demonstrated that anti-TGF-beta1 monoclonal antibody promoted the expansion of MNC and CD34(+) cells, and even more marked expansion of the more primitive progenitor cells-CD34(+)c-kit(-) cells. Meanwhile, it enhanced the output of more immature colony CFU-GEMM and BFU-E, but had no evident influence on the mature myeloid colony CFU-GM. It is concluded that the anti-TGF-beta1 monoclonal antibody can synergize other cytokines to enhance the proliferation of cord blood CD34(+) progenitor cells effectively, and it is more important that can reserve more primitive progenitor cells.
