ObjectiveTo investigate the relationship of the characteristics of sperm donors with the results of screening and provide some reference for the screening of sperm donors.

METHODSWe statistically analyzed the screening data about 12 362 sperm donors at the Guangdong Human Sperm Bank from January 2003 to June 2017 and the relationship of the eligibility rate of screening with the donors' age, education, occupation, marriage, and fatherhood.

RESULTSOf the 12 362 sperm donors, 3 968 (32.1%) met the standards of semen quality and 3 127 (25.3%) filled all the requirements of sperm donation. The eligibility rate of screening was 27.7% in the donors aged 20－24 years, 24.3% in those aged 25－29 years, 23.8% in those aged 30－34 years, and 17.5% in those aged =≥35 years (P < 0.01); 23.5% in the senior high school students, 24% in the junior college students, 25.9% in the undergraduates, and 30.3% in the postgraduates (P < 0.01); 29.3% in the students versus 22.9% in the others (P < 0.01), 41.5% in the married versus 20.7% in the unmarried (P < 0.01), and 45.6% in the fathers versus 20.9% in the childless husbands (P < 0.01).

CONCLUSIONSA higher eligibility rate of screening was found among the sperm donors aged <35 years or with a bachelor's or higher degree, particularly among students.

Sperm DNA damage is recognized as an important biomarker of male infertility. To investigate this, sperm DNA damage was assessed by the sperm chromatin dispersion (SCD) test in semen and motile spermatozoa harvested by combined density gradient centrifugation (DGC) and swim-up in 161 couples undergoing in vitro fertilization (IVF). Semen analysis and sperm DNA damage results were compared between couples who did or did not achieve pregnancy. The sperm DNA damage level was significantly different between the two groups (P < 0.05) and was negatively correlated with IVF outcomes. Logistic regression analysis confirmed that it was an independent predictor for achieving clinical pregnancy. The effects of different levels of sperm DNA damage on IVF outcomes were also compared. There were significant differences in day 3 embryo quality, blastocyst formation rate, and implantation and pregnancy rates (P < 0.05), but not in the basic fertilization rate between the two groups. Thus, sperm DNA damage as measured by the SCD appears useful for predicting the clinical pregnancy rate following IVF.

OBJECTIVETo investigate the effect of RYBP gene on sensitivity of HL-60 cells to chemotherapy drugs by using RNA interference.

METHODSPlasmid expressing RYBP specific shRNA was constructed and then was used to establish the RYBP knockdown stable HL-60 cell line. Q-PCR and Western blot were used to confirm the efficacy of RYBP gene silencing at mRNA and protein level respectively; then the DNA ladder and Annexin V labeled flow cytometry were used to detect cell apoptosis; CCK-8 was used detect the sensitivity of HL-60 cells to the chemotherapeutic drug cytarabine or daunorubicin.

RESULTSThe lentiviral-RYBP-shRNA vector was succesfully and effectively inhibit the expression of RYBP at mRNA and protein in HL-60 cells. It was found that without chemotherapy drug treatment the apoptosis rate of RYBP shRNA group was lower than that of the empty vector control group (NC group). When treated with cytarabine, the apoptosis rate and inhibitive rate of RYBP shRNA group were lower than those of NC group. Besides, when treated with daunorubicin, the apoptosis rate of RYBP shRNA group was lower than that of NC group, while the inhibitive rate had no significant difference.

CONCLUSIONSRYBP gene silencing can inhibitive the apoptosis of HL-60 cells and significantly reduce the sensitivity to cytarabine, but this gene silencing can't affect the sensitivity to daunorubicin.

OBJECTIVETo compare efficacy differences between fire filiform needle combined with mild moxibustion and gabapentin combined with sham acupuncture for postherpetic neuralgia (PHN).

METHODSOne hundred cases of PHN were randomly divided into a needle group and a medicine group, 50 cases in each one. In the needle group, pricking method of fire filiform needle was given at the Ashi points, and then mild moxibustion was applied for 15 min. In the medicine group, the oral administration of gabapentin capsule and sham acupuncture at non-acupoints in the distal end of lesions were applied. The treatment was required for 21 days in both groups. The visual analogue score (VAS) was recorded before treatment and on the 1st day, 2nd day, 3rd day, 6th day, 9th day and 12th day of treatment. The most severity of pain within last 24 h, preset severity of pain, immediate analgesia effect and starting time of pain relief were observed, also the efficacy was assessed and improvement of symptoms was observed in the follow-up visit.

RESULTSThe total effective rate was 94.0% (47/50) in the fire filiform needle group, which was superior to 86.0% (43/50) in the medicine group (P < 0.05). Compared with medicine group, the VAS of the most severity of pain within last 24 h was obviously reduced after the 2nd treatment in the fire filiform needle group while that of present severity of pain was relieved after the 1st treatment (both P < 0.05). The immediate analgesia effect in the fire filiform needle group was obviously superior to that in the medicine group in the first three times of treatment (all P < 0.05). The average time of pain relief was (3.91 +/- 0.82) days in the fire filiform needle group, which was significantly earlier to (6.53 +/- 1.13) days in the medicine group (P < 0.05). 26 cases were cured in the fire filiform needle group in the follow-up visit, which was superior to 2 cases in the medicine group (P < 0.05). The improvement of VAS, pain range and sleep quality in the needle group were also superior to those in the medicine group (all P < 0.05). The direct medical cost in the fire filiform needle group was (232.32 +/- 48.108) yuan, which was significantly lower than (466.00 +/- 41.09) yuan in the medicine group (P < 0.05). There was only one case of adverse effect in the medicine group during the treatment.

CONCLUSIONThe fire filiform needle combined with mild moxibustion could obviously relieve the pain in PHN patients, which has superior immediate analgesia effect and pain relieving time compared with gabapentin, which also has less adverse effects and cheap cost.

Objective To investigate the diagnosis and treatment of intracranial venous sinus thrombosis caused by trauma. Methods The clinical data of 13 patients had definite diagnosis by clinic and imaging, were analyzed retrospectively. Three patients received removal of hematoma and bone flap operation; 2 received anticoagulant therapy in early phase and intravenous thrombolysis; 2 accepted intrasinus interventional catheter-directed thrombolysis; ventriculoperitoneal shunt operation was performed in 1 patient for enjoying sub-optimal effects of conservative treatment; and the other 5 patients with transverse sinus embolism accepted conventional treatment for their symptom-free or having mild symptom. Results Intracranial venous sinus thrombosis caused by trauma was likely to locate in the superior sagittal sinus and transverse sinus; these patients mostly manifested as severe diffuse brain swelling combined with a fractured skull, epidural hematoma or intracerebral hematoma. Ten patients got clinical cure, 2 focal symptom and 1 mild mental retardation. Three days to 6 months after treatment, good results were noted in 8 patients performed DSA and in 5 patients performed MRV. Conclusion Early treatment should be given once the definite diagnosis is made in patients with intracranial venous sinus thrombosis caused by trauma, and anticoagulant and thrombolytic therapy are the main methods.
