Primary mediastinal large B-cell lymphoma represents a distinct entity with unique clinicopathologic features and a molecular gene-expression signature. There is no standard regimens. Retrospective analysis suggests that dose-dense and dose-intensive regimens are more effective than CHOP. The addition of rituximab may mitigate such difference. The role of mediastinal radiotherapy upon completion of chemotherapy remains unclear. The role of PET scanning requires prospective examination, which may allow the de-escalation of treatment if it can be shown to yield reliable prognostic information.

Objective To compare the efficacy and toxicity of melphalan + prednisone + thalidomide regimen (MPT) and melphalan + prednisone regimen (MP) in the treatment of multiple myeloma (MM).was given 100-200 mg/d everyday. 21 cases in MP group, the dose of melphalan and prednisone were the same as that in MPT group. The efficacy was evaluated after 6 cycles of treatment. Results The overall response rate (ORR) of MPT group and MP group were 65.4 % and 42.9 %, respectively (P＞O.05). The median response time in MPT group versus MP group was 2 months versus 3 months. Compared with the MP group. the increase of hemoglobin and albumin concentration in the MPT group is significantly higher (P＜ 0.05).The incidence of adverse effects of MPT group was higher than that of MP group (P ＜0.05), but the percentage of grade 3 and grade 4 toxicity was no different. The median PFS in MPT group was 11 months, 2-year PFS was 66.18 %. Conclusion Compared with MP, MPT could achieve higher response rate, improve the life quality and prolong the survival time of MM patients with better tolerance.

Objective To investigate the prognostic factors in acute myeloid leukemia subtype M2 (AML-M2) patients with chromosome translocation of 8 and 21. Methods By using G-banding analyses karyotype and combining the clinical data, prognostic factors in 94 cases of de novo adult AML-M2 in our hospital from 2001 to 2007 were retrospectively analyzed. Results Chromosome 8 and 21 translocation were identified in 53.2 % (50/94) of AML-M2 cases. In the patients with other aberrations in addition to t(8;21), their complete remission (CR) rates, overall survival (OS) was lower than the patients with sole t (8;21) and normal karyotype(P <0.05). And the patients with sole t (8;21) whose CR rates and OS had no difference with patients with normal karyotype (P>0.05). The patients were divided into 3 subgroups (low index, less than 2.5;intermediate index, 2.5-20;high index, 20 or more) according to WBC index. The CR had no difference among the 3 subgroups, but the OS of the 3 subgroups was different (P<0.05). The OS in the lowest index group was longer than that in the others. Conclusion Cytogenetically, 53.2% cases had chromosome 8 and 21 translocation, 46 % cases had t(8;21) with additional chromosomal abnormalities, and the main additional abnormalities were loss of a sex chromosome (LOS). t(8;21) AML-M2 patients with additional chromosome abnormalities had low complete remission rate and shorter survival time, and its prognosis was poorer. WBC index have no influence on complete remission rate but effected the survival time.

Objective To investigate the application of U100plus laser in treating incarcerated in gallbladder stones. Methods The clinical data of 52 patients accepted U100plus laser lithotripsy of gallbladder neck incarcerated were retrospective analyzed. Results All 52 patients were successful treated by surgery. Twelve patients with gallbladder wall edema, drainage tubes were used to prevent bile leakage after gallbladder surgery. After 2~4 d, the ultrasound examination showed that no abnormal drainage, and tube was removed. The mean operative time was 40 min. The mean intraoperative bleeding was 2 mL. Patients were able to get out of bed 1 day after surgery. The average length of hospital stay was 4 d. Pa-tients were followed up for 6 to 30 months, and no special discomfort, The ultrasonography showed no stone recurrence. Conclusion U100plus laser lithotripsy is a safe and effective method for treating incarcerated gallbladder stones.

Objective To investigate the effect of maternal deprivation (MD) on neurobehavior and PP1Cγgene expression in hippocampus. Methods Male pups were randomly divided into MD group(thirty-five)and control group(twenty-four). From PND 1 to PND 21 ,pups in the MD groups underwent daily maternal deprivation for 3 h ( Postnatal day). Neurobehavior was observed to investigate neurodevelopment, Morris water maze was used to measure spatial learning and memory,and Real-Time quantitative PCR was employed to analyze PP1Cγ gene expression. Results Several significant deficiencies were observed in bodyweight and grasping reflex while a great enhancement in hot-plate test in rat pups suffering from MD( (26.23 ± 2.81 )g vs. (30. 38 ± 3.85 )g;( 19.37 ± 11.89) s vs. (22.39 ± 17.62 ) s; (4.36 ± 1.76 ) s vs. ( 5.26 ± 2.55 ) s; P ＜ 0. 05 ), but deficiencies in neurological reflexes were subtle ( ( 0.83 ±- 0.30 ) s vs. ( 0. 83 ± 0. 34 ) s; ( 3.68 ± 1.63 ) s vs. ( 5.61 ± 3. 01 ) s;( 3.00 ± 0.00 ) vs. ( 3.00 ± 0. 00); P ＞ 0. 05 ). MD had a subtle influence on spatial learning and memory (P ＞0.05). Meanwhile,MD could lead to PP1Cγ expression down-regulation on PND 22 ( (2.19 ±0.62) vs. (3.52 ±0.86), P＜0. 05)which was in line with early neurobehavior results. No difference was found compared with MD group and control group on PND60 ( ( 1.73 ± 0. 78 ) vs. ( 1.33 ± 0. 34); P ＞ 0.05 ). However, there was the up-regulation of PP1Cγexpression on PND 90 ( (2.85 ± 0. 34) vs. ( 1.34 ± 0.93 ); P ＜ 0.05 ). Conclusion MD alters early neurobehavior and hippocampal PP1Cγgene expression in the Wistar rats,but has a subtle effect on learning and memory. At the same time,MD can make PP1Cγexpression in the hippocampus varying with the age.

This paper studied the diagnosis and embryology of 20 cases lacking one pulmonary artery out of 2040 patients operated for tetralogy of Fallot. History of severe cyanosis syncope and hemoptysis was usually present in the majority of these patients. The important diagnosis characteristic was asymmetry of plumonary vascularity on X-ray film and the decrease of pulmonary cascular markings on the side without plumonary artery. A right ventricular cardiogram can confirm the absence of one pulmonary artery or the blind-end like change.

Objective To explore the distribution characteristics of plasma renin concentration in patients with hypertension and the possibly methodological problems.Methods The subjects including 361 patients with hypertension[male: 184 cases, average age: (45.16±13.74)years old;female: 177 cases, average age: (51.04±12.68) years old]and 187 apparent healthy individuals[male: 92 cases, average age: (46.74±13.17)years old;female: 95 cases, average age: (47.33±13.18) years old]were recruited from Departments of Healthy Check-up and outpatients for hypertension in Tangshan Gongren Hospital. The plasma renin concentration was detected by chemiluminescence-Immunoassay.Results The plasma renin concentration shows log-transformed normal distribution both in healthy group and hypertension group. The range of plasma renin concentration in hypertension group is from 0.05 to 574.07 pg/ml, while that in apparent healthy group is from 3.24 to 120.40 pg/ml. The plasma renin concentration in both groups is higher in male than female (Hypertension t=2.19,P=0.029;Healthy people t=2.85,P=0.005). The average concentration of plasma renin in hypertension group is slightly higher, and the width of density distribution is larger in comparison with healthy group although there is no significant difference between them. However, the percentage of plasma renin abnormality was 26.59% (96/361) in hypertension group with 13.85%(50/361)of low renin subtype and 12.74%(46/361)of high renin subtype ConclusionsThe plasma renin concentration measured by Chemiluminescence-Immunoassay can be used as an effective tool for hypertension screening.

ObjectiveTo investigate the variation of peripheral blood CD34+ cells during the hematopoietic stem cell mobilization,and its influence on the collecting timing and results.Methods Twenty-seven cases of peripheral blood hematopoietic stem cell mobilization and collection from April 2010 to December 2011 were analyzed,including 13 autologous cases mobilized with chemotherapy combined with granulocyte colony-stimulating factor (G-CSF,10 μg· kg-1 · d-1) and 14 cases of healthy donors mobilized with only G-SCF (7.5 μg · kg- 1 · d- 1 ).The number of peripheral blood CD34+ cells was counted,and its correlation with the yield of mononuclear cells (MNCs) and CD34+cells was analyzed.ResultsMNCs (5.84 ± 1.48) × 108/kg and CD34+ cells (3.93 ± 2.16) × 106/kg were obtained in healthy donors,and (6.58 ± 3.72) × 108/kg MNCs and (3.98 ± 3.06) × 106/kg CD34+ cells were obtained in autologous cases,respectively.There was only 1 failure in autologous cases.The peak of peripheral blood CD34+ cells in autologous cases appeared at day 4 after the treatment of G-CSF,and in healthy donors the number of peripheral blood CD34+ cells at day 5 was still in ascendant phase.The CD34+ cells/kg in the collection products were positively correlated with the percentage and absolute value of peripheral blood CD34+ cells.The cases ratio of CD34+ cells≥2× 106/kg in the products of single collection was up to 76.2％ (16/21) in the cases with peripheral blood CD34+ cells absolute value greater than 20/μl.ConclusionThe number of peripheral blood CD34+ cells was an important monitoring indicator in hematopoietic stem cell mobilization and collection,CD34+ cell absolute value ≥20/μl could be used as collection threshold.

The protective efficacy of DNA plasmids encoding avian infectious bronchitis virus (IBV) S1, N, or M protein was investigated in chickens. Chickens were inoculated monovalently (with plasmid pVAX1-16S1, pVAX1-16M, or pVAX1-16N alone) or multivalently (combination of the three different plasmids, pVAX1-16S1/M/N). A prime-boost immunization protocol against IBV was developed. Chickens were immunized with the multivalent DNA vaccine twice and then boosted with an inactivated vaccine once. Antibody titers of the chickens immunized with pVAX1-16S1/M/N were much higher than those of the monovalent groups (p < 0.01). A protective rate up to 90% was observed in the pVAX1-16S1/M/N group. The serum antibody titers in the prime-boost birds were significantly higher than those of the multivalent DNA vaccine group (p < 0.01) but not significantly different compared to the inactivated vaccine group at 49 days of age. Additionally, the prime-boost group also showed the highest level of IBV-specific cellular proliferation compared to the monovalent groups (p < 0.01) but no significant difference was found compared to the multivalent DNA vaccine group, and the prime-boost group completely protected from followed viral challenge.

Objective: This study aims to explore the relationships of family functioning, general well-being, and exercise with psychological distress.Furthermore, we investigated the special roles of general well-being and exercise on the association between family functioningand psychological distress. Methods: Of 769 end-stage renal disease (ESRD) patients participated in the cross-sectional study which consisted of the 12-item GeneralHealth Questionnaire (GHQ-12), the Family APGAR Scales, and the General Well-Being Schedule. The collected data were analyzedusing multiple linear regression analysis and path analysis. Results: The prevalence of psychological distress was 72.3%. Family functioning, general well-being and exercise were associated factorsof psychological distress (p<0.05). The indirect effect of family functioning on psychological distress was partially mediated by generalwell-being (Effect=-0.08, 95% CI=-0.11, -0.04). In addition, the effect of family functioning on general well-being was moderated byexercise (Index=-0.092, SE=0.033, 95% CI=-0.159, -0.029). Conclusion The prevalence of psychological distress among ESRD patients was high. Family functioning, general well-being and exercisewere associated with psychological distress. Family functioning could affect psychological distress partially by affecting general wellbeing.Furthermore, exercise had a significant moderating effect on the relationship between family functioning and general well-being.Psychiatry Investig 2020;17(4):356-365
