RESUMO
【Objective】 To investigate the psychological status of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), and to analyze the effects of anxiety on the total National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) in patients in Ngari Prefecture of Tibet. 【Methods】 CP/CPPS patients treated during Oct.2019 and Oct.2021 were involved and divided into anxiety group and non-anxiety group. The non-anxiety group received routine drug treatment, while the anxiety group received drugs and psychological intervention. 【Results】 A total of 117 patients were involved, including 68 in the anxiety group and 49 in the non-anxiety group. There were no statistical differences between the two groups in terms of age, body mass index (BMI), marital status, smoking history, and education level (P>0.05). The total NIH-CPSI score in the anxiety group (18.53±3.47) was higher than that in non-anxiety group (15.67±3.33), which was mainly manifested by the increase of pain and decrease of quality of life scores. Further stratification of anxiety level revealed that quality of life score and total NIH-CPSI score increased as anxiety symptoms worsened. After drug treatment, pain and urination symptoms were improved in the non-anxiety group, but the quality of life score and total NIH-CPSI score did not change significantly. After psychological intervention, the anxiety group had lower total NIH-CPSI score and other scores. 【Conclusion】 It is not uncommon for CP/CPPS patients to have a comorbidity of anxiety. The increase in the total NIH-CPSI score is caused by the increase of pain score and decrease of quality of life score. Active psychological intervention can improve anxiety, urinary symptoms, pain symptoms and quality of life.
RESUMO
Objective To investigate the effect of Euphorbia helioscopia on MDA-MB-231 cells and its mechanism.Methods The cell viability was detected by MTT assay.The production of ROS in MDA-MB-231 cells was measured by fluorescence microscopy.The apoptotic rate was detected by flow cytometry.Apoptosis DNA fragments were detected by TUNEL assay.Western blot was used to assess the expression of caspase-9, caspase-3 and PARP.Results MTT assay showed that the extract significantly inhibited the viability of MDA-MB-231 cells, which can be diminished by the ROS inhibitor NAC and the caspase inhibitor Z-VAD-FMK.The marked increase in the production of ROS induced by the extract was observed with fluorescence microscopy.Flow cytometry showed that the PI positive staining cells increased significantly after the treatment of the extract, but was diminished by NAC.Caspase-9 and caspase-3 were activated after the treatment of the extract while the PARP was cleaved.TUNEL showed that a significant increase in apoptotic DNA fragmentation induced by the extract, which can be diminished by NAC and Z-VAD-FMK.Conclusion Ethyl acetate extract inhibited the MDA-MB-231 cells and induced apoptosis.The mechanism may involve with the mitochondrial damage due to the excessive ROS.
RESUMO
BACKGROUND:Intra-articular injection of sodium hyaluronate is an effective method for the treatment of knee osteoarthritis, with significant effect and less adverse reactions, but the mechanism is unclear. OBJECTIVE:Through testing the malondialdehyde and superoxide dismutase levels in the synovial fluid of knee osteoarthritis before and after injection of sodium hyaluronate, to evaluate the clinical efficacy of sodium hyaluronate in the treatment of knee osteoarthritis. METHODS:Thirty-seven patients with knee osteoarthritis (40 knees) were enroled and divided into mild (n=10, 10 knees), moderate (n=17, 18 knees), and severe (n=10, 12 knees) groups according to the Japan's knee osteoarthritis indications. Patients were subjected to intra-articular injection of 25 mg sodium hyaluronate, once a week for 5 weeks. The levels of malondialdehyde and superoxide dismutase in the synovial fluid before and 4 weeks after treatment were detected, and then clinical effects were evaluated based on the clinical scores according to the Japan’s knee osteoarthritis indications. RESULTS AND CONCLUSION: The indication rating results of the mild and moderate groups were decreased significantly 4 weeks after injection (P < 0.05), but there were no significant difference in the severe group before and after treatment. The malondialdehyde level in the synovial fluid was decreased obviously in the three groups at 4 weeks after injection (P < 0.05), while the level of superoxide dismutase was increased remarkably (P < 0.05). These findings indicate that sodium hyaluronate can treat knee osteoarthritis by reducing the malondialdehyde level and increasing superoxide dismutase level in the synovial fluid, but this method is more suitable for treatment of mild to moderate knee osteoarthritis.
RESUMO
Objectives To investigate the efficacy and toxicity of bortezomib based combination therapy for Chinese patients with relapsed or refractory multiple myeloma(MM),and to determine the combination regimen,dosage and cycles in application of bortezomib for MM therapy.Methods Forty-six patients with refractory or relapsed myeloma were treated with bortezomib(1.3 mg/m2)as an intravenous bolus twice weekly for 2 weeks on day 1,4,8,and 11 in a 3-4 week cycle,in combination with dexamethasone,dexamethasone plus thalidomide, CD(C-cytoxan,D-dexamethasone),MD(M- mitoxsnteone),DCEP(E-etoposide,P-platinol),and DT-PACE regimens(T-thalidomide,A-adriamycin). Response to bortezomib was evaluated according to the criteria of the International Myeloma Working Group (IMWG)before initiation of each cycle.Adverse events were graded according to the National Cancer Institute Common Toxicity Criteria,version 3.0.Forty-nine matched patients with relapsed and refractory MM who received thalidomide based combination therapy were used as a historical control group.Results Among 43 of the 46 patients whom could be evaluated,the overall response rate was 72.1%(the control group was 51.0%,P＜0.05),including complete response in 5 patients(11.6%),very good partial response in 12 patients(27.9%),and partial response in 14 patients(32.6%).The overall response rate after one and two cycles was 30.2%and 58.1%(P＜0.05),respectively.The frequent adverse events were thromboeytopenia(62.8%),fatigue(55.8%),nausea(51.2%)and peripheral neuropathy (30.2%);all of the events could be tolerated.The most common adverse event in the control group was constipation(69.4%),followed by fatigue(59.2%)and dizziness(46.9%).Conclusions Bortezomib based combination therapy is a new effective therapy in relapsed or refractory myeloma patients with a higher response rate and difierent toxicities as compared with thalidomide based combinations.

RESUMO
Purpose:To investigate the effects and side- ef fects of thalidomide in the treatment of relapsed and refractory multiple myelom a (MM).Methods:There were thirteen men and two women aged 33～7 6 (median 58) years in thalidomide alone group. Two cases were newly diagnosed my eloma; twelve of them were refractory myeloma, including three relapsed cases wh o had experienced autologous peripheral blood stem cell transplantation (AutoPBS CT); another one is primary plasma cell leukemia. The starting dose was 100mg/d, escalating up to a maximum of 800mg/d. The combination group included twenty me n and seven women aged 40～81 (median 56) years of which case was newly diagnose d myeloma; twenty-five cases were refractory myeloma, two of whom relapsed after AutoPBSCT; another one was primary plasma cell leukemia. Dexamethasone 40mg/d w as used at d 1-4 , d 9-12 , d 17-20 when the dose of thalidomide increased to 400mg/d. Each cycle lasted for one month.Results: The total response rate was 42.9% and 57.7% in thalidomide alone group and in co mbination group, respectively. The response rate in refractory patients was 33.3 % and 44.0% in thalidomide alone group and in combination group, respectively. T here was no difference between the two groups in response rates. Both of the two groups had side effects of constipation and skin rash, etc. in different degree s but usually tolerable. Conclusions:Both thalidomide alone and thalidomide combined with dexamethasone was effective in the treatment of relap sed and refractory MM.
RESUMO
Objective To sum up the clinical experience of the diagnosis and treatment of membranous glomerulopathy associated with chronic graft-versus-host disease(cGVHD) following allogeneic stem tell transplantation(alloSCT).Methods One case of acute acute lymphoblastic leukemia(received) HLA complete matched alloSCT and subjected to methopterin and Tacrolimus(FK506)postoperatively for prevention of GVHD.Nineteen days after operation,the patient suffered from(acute) GVHD and recovered by using methylprednisolone.On the day of 182 and 235 after transplantation,FK506 and prednisone were withdrawn.Five days later,cGVHD occurred,showing liver(dysfunction) and nephrotic syndrome.Membranous glomerulopathy(stage II) was pathologically (diagnosed) and treated with FK506 and prednisone.Results In membranous glomerulopathy,the(patient) got albuminuria(++++),leukocytes 75/?L,epicytes(359.5)/?L,pathological casts(+),24-h urine protein(4.28) g.Renal biopsy revealed that glomeruli were slightly enlarged,partial(capillary) compressed to be closed,glomerular basement membrane(GBM) was slightly thickened and mesangium slightly proliferate.Masson stain indicated the deposition of pink material along the glomerular capillary walls.And IgG(+++),C3(+++) and IgA(++) were detected at the GBM in a granular pattern by immunofluorescent stain.Electron microscopy showed numerous subepithelial(deposits).After treatment with prednisone and FK506 for 2 months,proteinuria was gradually(decreased).Conclusions GVHD associated membranous glomerulopathy should be considered when the patient got nephrotic syndrome or proteinuria after alloSCT.Renal biopsy is beneficial to the diagnosis of GVHD.Glucocorticoid and FK506 is effective in the treatment of GVHD.
