OBJECTIVESTo assess the effect of transrectal prostatic biopsy (TPB) on the concentrations of serum prostate specific antigen (PSA).
METHODSTwenty patients with abnormal PSA levels and/or digital rectal examination (DRE) underwent TPB. Serum PSA levels were measured before TPB and at 0.5 h, 1 week, 1 month after TPB, respectively.
RESULTSThe serum PSA levels before TPB and 0.5 h, 1 week, 1 month after TPB were (12.23 +/- 8.62), (34.90 +/- 41.53), (23.59 +/- 20.78) and (11.31 +/- 6.95) micrograms/L, respectively. The serum PSA concentration was significantly higher at 0.5 h after TPB than before (P < 0.05), and then gradually decreased. PSA levels remained higher for at least 1 week in 85% (17/20) patients(P < 0.05), then returned to the baseline at one month after TPB (P > 0.05).
CONCLUSIONSTPB can lead to a dramatic increase of PSA in serum and keep the PSA value high in one week. Then the PSA in serum decreased gradully. Serum PSA level cannot return to baseline until one month after TPB.

OBJECTIVETo evaluate the efficacy and safety of IDA (Haizheng Parmacy, China) in the treatment of acute leukemia.
METHODSA multi-institutional single-blind randomized controlled clinical trial was carried out. A total of 155 newly diagnosed patients with AML and ALL were enrolled. The patients were randomly divided into two groups, one was given IDA (n = 77) and the other given zevodas (Pharnacia & Upjohn, n = 78) for comparison.
RESULTSAll the patients enrolled in this trial were eligible for assessment of side effects, and 129 patients for evaluation of overall response rate. In patients treated with IDA vs zevodas, the overall response rate (OR) was 78.1% vs 76.9%, CR was 68.8% vs 67.7%; in AML patients, OR was 82.4% vs 71.8%, and CR was 76.5% vs 64.1%; in ALL patients, OR was 80.0% vs 81.8%, and CR was 68.0% vs 68.2%. There was no sitatistically significant difference in hematologic and non-hematologic toxicities between the two groups.
CONCLUSIONThe efficacy of IDA in the treatment of acute leukemia is comparable to that of zevodas. Both have similar toxic side effects.

OBJECTIVETo demonstrate the clinical outcomes of maximal medical therapy(MMT) and functional endoscopic sinus surgery+ maximal medical therapy (FESS+MMT) for moderate to severe chronic rhinosinusitis without nasal polyps (CRSsNP) in China, to provide clinical evidence for treatment recommendation.
METHODSA prospective multicenter case control study consisting of 90 strictly selected CRSsNP patients were carried out by ENT Hospital of SUN Yet-sen university and 7 other university affiliated hospitals across China from March 2011 to October 2012. All patients were selected to MMT group or FESS+MMT group followed by 3 months treatment and 6 months follow up. Treatment efficacy evaluation indicators included improvement of visual analogue scale (VAS) score, quality of life, CT score and post-operative nasal endoscopic evaluations. SPSS16.0 software was used to analyze the data.
RESULTSAll patients enrolled complied with moderate to severe CRSsNP evaluation criteria. There were no significant differences found in the baseline data between two groups (P > 0.05). (1) At the 3 time points (pre-treatment, 3 months and 6 mongths after treatment) , VAS overall symptom score in MMT group were 6.52 ± 2.61, 2.66 ± 2.10, 2.40 ± 1.56, significant differences were found among them (t value were 2.083 and 2.295, both P < 0.05); in FESS+MMT group the values were 6.99 ± 2.70, 0.95 ± 0.84, 0.60 ± 0.81, significant differences were found among them (t value were 3.582 and 5.196, both P < 0.05); SNOT-20 score in MMT group were 38.61 ± 17.36, 18.59 ± 14.04, 18.40 ± 8.91, significant differences were found among them (t value were 2.737 and 2.657, both P < 0.05); in FESS+MMT group the values were 38.21 ± 19.61, 5.94 ± 5.01, 2.65 ± 2.31, significant differences were found among them (t value were 3.247, 3.319, both P < 0.05). (2) FESS+MMT group relative to the MMT group in VAS overall symptom score and quality of life improvements appeared earlier and were more pronounced. (3) Overall treatment efficacy showed that in MMT group: complete control 14 cases (30.4%), partially control 31 cases (67.4%), uncontrolled 1 cases (2.2%); In FESS+MMT group: complete control 17 cases (38.6%), partially control 26 cases (59.1%), uncontrolled 1 cases (2.3%). (4) Patients' satisfaction survey showed that the number of the patients who were very satisfied with the efficacy in the FESS+MMT group were 2 times higher than the MMT group.
CONCLUSIONS(1) For moderate to severe CRSsNP, both MMT and FESS+MMT treatment can effectively control the overall symptoms and classified symptoms, reduce CT scores and significantly improve the quality of life, the ineffective rate is less than 5%. (2) FESS+MMT group in terms of improving symptoms and the onset time are better than MMT group, especially in improving the stuffy nose, head and face fullness, and mental and physical symptoms are better than MMT group. (3) FESS+MMT group showed better results in patient satisfaction survey compared to the MMT group. Therefore for moderate to severe CRSsNP patients, FESS+MMT therapy could be recommended as the preferred treatment.

OBJECTIVETo evaluate the safety of domestically produced idarubicin in the treatment of acute leukemia by a multicenter randomized control trial.
METHODSThis trial was carried out in the hemotologica department of five hospitals throughout China, with hospitalized patients who suffered from acute myelogenous leukemia ( AML except M3 type) , acute lymphocytic leukemia ( ALL) , chronic myelogenous leukemia-blast (CML-blast) , totally 155 patients. Those with severely cardial, hepatic or renal disfunction or those who had ever treated with > or = 200 mg/m(2) idarubicin were excluded from the trial. All patients signed the letter of consent as required by the Ethics Committee of our government. In this study, 155 leukemia patients were randomly grouped into: 1. test group treated using domestic idarubicin, 2. control group using imported idarubicin. The acute myelogenous leukemia regimen included idarubicin 8 mg/m(2), dl -3 plus cytosine arabinoside 100 mg/m(2), dl - 7 for 1-2 cycles. The regimen for acute lymphocytic leukemia was idarubicin 8 mg/m2, dl - 3; vincristine 2 mg/mr, dl; cyclophosphamide 750 mg/m2, dl ; plus prednisone 60 mg/m(2),dl - 14 for 1-2 cycles.
RESULTSClinical response rate of the tested group treated with domestic idarubicin and control group treated with imported idarubicin was 78. 1% (50/64) vs. 76.9% (50/65) without any statistically significant difference between the two groups(P >0. 05). Grade Ill - IV hematological toxicity rate of the domestic idarubicin group and imported idarubicin group was 74. 0% vs. 73. 1% , respectively (P = 0. 73). Drug-related death was observed in 3 of 77 patients in the domestic idarubicin group (3.9%) due to cerebral hemorrage or septic infection. The incidence of non-hematological toxicities in domestic idarubicin group and imported idarubicin group was 84. 4% vs. 79. 5% for nausea or vomiting, 70. 1% vs. 71. 8% for infection, 42. 9% vs. 41. 0% for mucositis, 33. 8% vs. 33. 3% for alopecia, 28.6% vs. 28. 2% for serum glutamicoxalacetic transaminase abnormalitis, 16. 9% vs. 10. 3% for cardiac toxicity, all without statistically significant differences between these two groups (P > 0. 05). Discontinuation of treatment due to non-hematological toxicity was not neccessary.
CONCLUSIONDomestic idarubicin is comparable to imported counterpart in efficiency and safety for the treatment of acute leukemia. The most severe side effects of domestic idarubicin is hematological toxicity, which should be closely observed and treated in time, while its non-hematological toxicity is tolerable.

In the present study, we evaluated the impact of sperm origins and concentration on the clinical outcomes of intracytoplasmic sperm injection (ICSI) cycles. A total of 1201 ICSI cycles were retrospectively analyzed for male azoospermia or oligozoospermia between January 2015 and December 2015 in the Peking University Third Hospital. Patients were divided into three groups (Group 1 vs Group 2/3; surgically extracted sperm vs ejaculated sperms): Group 1 included 343 ICSI cycles and Group 2 analyzed 388 cycles on semen with sperm concentration <5 × 106 ml-1 (severe oligozoospermia group). Group 3 included 470 cycles with sperm concentration between 5 × 106 ml-1 and 15 × 106 ml-1 (mild oligozoospermia group). Fertilization rates, clinical pregnancy rates, and live birth rates were analyzed and compared among groups of different semen origins and concentrations on the oocyte retrieval day. Group 2 showed a lower fertilization rate than Group 3 (62.9% ± 21.6% vs 66.8% ± 22.1%,P< 0.05). There were no statistically significant differences in clinical pregnancy rate per transfer (51.3%, 46.7%, and 50.0%, respectively), live birth rate per transfer (44.4%, 40.9%, and 41.4%, respectively), accumulative live birth rate (58.3%, 51.0%, and 52.1%, respectively), twin birth rate (18.4%, 10.6%, and 12.6%, respectively), and birth defects rate (0, 0.3%, and 0.2%, respectively) among three groups. The results of this study indicated that sperm origins and concentration do not impact the clinical outcomes in ICSI cycles.

Amyotrophic lateral sclerosis (ALS) is a complex neurodegenerative disease with cellular and molecular mechanisms yet to be fully described. Mutations in a number of genes including SOD1 and FUS are associated with familial ALS. Here we report the generation of induced pluripotent stem cells (iPSCs) from fibroblasts of familial ALS patients bearing SOD1 and FUS mutations, respectively. We further generated gene corrected ALS iPSCs using CRISPR/Cas9 system. Genome-wide RNA sequencing (RNA-seq) analysis of motor neurons derived from SOD1 and corrected iPSCs revealed 899 aberrant transcripts. Our work may shed light on discovery of early biomarkers and pathways dysregulated in ALS, as well as provide a basis for novel therapeutic strategies to treat ALS.

Xeroderma pigmentosum (XP) is a group of genetic disorders caused by mutations of XP-associated genes, resulting in impairment of DNA repair. XP patients frequently exhibit neurological degeneration, but the underlying mechanism is unknown, in part due to lack of proper disease models. Here, we generated patient-specific induced pluripotent stem cells (iPSCs) harboring mutations in five different XP genes including XPA, XPB, XPC, XPG, and XPV. These iPSCs were further differentiated to neural cells, and their susceptibility to DNA damage stress was investigated. Mutation of XPA in either neural stem cells (NSCs) or neurons resulted in severe DNA damage repair defects, and these neural cells with mutant XPA were hyper-sensitive to DNA damage-induced apoptosis. Thus, XP-mutant neural cells represent valuable tools to clarify the molecular mechanisms of neurological abnormalities in the XP patients.
