OBJECTIVETo explore various factors affecting the clinical pregnancy outcomes of artificial insemination with donor sperm (AID).
METHODSWe retrospectively analyzed 15,744 cycles of AID in 6302 women and investigated the association of the clinical pregnancy outcomes of AID with the treatment protocols, the times of insemination per cycle, the age of the infertile women, the status of the oviduct, and the number of AID cycles.
RESULTSThe pregnancy rate of AID was higher in the chlomiphene-treated women than in those of the natural cycle group (P = 0.003) but showed no significant differences either between the chloramiphene and human menopause gonadotropin (HMG) or between the HMG and natural cycle groups (P > 0.05), and so was it in the women that had received AID twice per cycle before and after ovulation (26.3%) than in those that had undergone only once before (7.0%) or after ovulation (23.7%) (P < 0.05). However, the pregnancy rate was remarkably lower in the women aged 35-40 years (16.5%), especially in those over 40 years (1.2%), than in those under 35 years (26.0%) (P < 0.05). There was no significant difference in the success rate of AID between the women with oviductal adhesion and those without (27.4% vs. 28.1%, P > 0.05). The pregnancy rate of the first cycle of AID (27.6%) was markedly higher than those of the second (24.7%), third (23.9%), and fourth (23.1%) (P < 0.01), but with no significant differences among the latter three cycles (P > 0.05), while that of the fifth cycle (19.0%) was remarkably lower than those of the first four (P < 0.01).
CONCLUSIONThe age of the infertile women is an important factor affecting the success rate of AID. AID twice per cycle is better than once only. For those without oviductal factors, at least 4 cycles of AID are required before in vitro fertilization.

Objective Color doppler ultrasonography of chronic Keshan disease (CKD) was evaluated to provide evidences for clinic diagnosis of the disease. Methods From September to Novermber 2009, according to "Diagnostic criteria of Keshan disease" (GB 17021-1997), 64 cases of CKD were randomly sampled from five Keshan diseased districts in Shandong province, Zoucheng, Sishui, Yishui, Wulian, Jvxian, and Pingyi as patient group. Thirty four healthy volunteers being checked up by Shandong Institute for Endemic Diseases Control and Research were put in control group. All the subjects were examined with Color doppler ultrasonography. The indexes of cardiac structure, left ventricular (LV) systolic function and LV diastolic function were measured.Results Left atrial internal diameter, LV end-diastolic internal diameter, LV end-systolic internal diameter, right ventricular diameter, aorta diameter, right atrial transverse diameter, right atrial long diameter and left ventricle mass of the patient group[(35.38 ± 6.89), (61.57 ± 8.61), (45.39 ± 10.29), (17.22 ± 3.79), (28.69 ± 2.81),(38.00 ± 6.05), (42.68 ± 8.65)mm, (283.22 ± 103.12)g] were higher than that of control group[(26.70 ± 3.27),(45.41 ± 4.93), (26.91 ± 4.35), (13.76 ± 2.27), (24.09 ± 2.89), (31.50 ± 3.32), (35.82 ± 3.14) mm, (156.03 ±39.86)g, t = 6.93, 10.09, 9.98, 4.87, 7.64, 5.81, 4.46, 6.90, all P< 0.05]. The LV ejection fraction and fractional shortening of the left ventricular of the patient group[(49.25 ± 14.33)%, (26.11 ± 9.17)%] were lower than that of control group[(73.88 ± 4.04)%, (42.88 ± 3.62)%, t = - 9.79, - 10.22, all P< 0.05]. Diffuse hypokinetic motion of the left ventricle reduced in 95% (61/64) of CKD patients, and 5% (3/64) of CKD patients had segmental LV dyskinesia. Seventy five per sent(48/64) of the patients accompanied with mitral regurgitation, and 39% (26/64) of these cases accompanied with tricuspid regurgitation. Meaningful Mitral or tricuspid regurgitation was not found out in control group. Conclusions The CKD patients' bore of atrio-ventricular cavity and LV mass are enlarged, and their motion of ventricle is reduced or partly reduced. They have poor heart function. Mitral regurgitation are more than tricuspid regurgitation. Color doppler Ultrasonography is important in diagnosis of chronic Keshan discase.

OBJECTIVETo evaluate the clinical efficacy of autologous semitendinosus and gracilis tendon grafting with anchor repair for the treatment of chronic achilles tendon rupture and severe scarring.
METHODSFrom April 2010 to October 2012,26 patients with chronic achilles tendon rupture(with Myerson type III ) and severe scarring were treated with autologous semitendinosus and gracilis tendon grafting with anchor repair. There were 19 males and 7 females,with an average age of 32 years old (ranged, 22 to 47 years). The time from injury to surgery was from 3 to 12 months (7 months on average). The plantar flexion strength of all injuried feet attenuated and single heel rise test were positive in 26 cases before operation. Plaster immobilization and routine rehabilitation therapy were performed after operation. Clinical effects were evaluated by Arner-lindholm criterion and complications were observed after operation.
RESULTSAll the patients were followed up from 12 to 24 months with a mean of 16 months. No complications such as achilles tendon re-rupture, wound infection, etc were found during follow-up period. According to the Arner-Lindholm standard, 15 cases got excellent results and 11 good.
CONCLUSIONUsing autologous semitendinosus and gracilis tendon grafts with anchor repair to treat chronic achilles tendon rupture and severe scarring is a perfect surgical procedure.

To construct the Bac-to-Bac expression system of Bombyx mori nucleopolyhedrovirus (BmNPV), a transfer vector was constructed which contained an Escherichia coli (E. coli) mini-F replicon and a lacZ: attTN7: lacZ cassette within the upstream and downstream regions of the BmNPV polyhedrin gene. B. mori larvae were cotransfected with wild-type BmNPV genomic DNA and the transfer vector through subcutaneous injection to generate recombinant viruses by homologous recombination in vivo. The genomic DNA of budded viruses extracted from the hemolymph of the transfected larvae was used to transform E. coli DH10B. Recombinant bacmids were screened by kanamycin resistance, PCR and restriction enzyme (REN) digestion. One of the bacmid colonies, BmBacJS13, which had similar REN profiles to that of wild-type BmNPV, was selected for further research. To investigate the infectivity of BmBacJS13, the polyhedrin gene was introduced into the bacmid and the resultant recombinant (BmBacJS13-ph) was transfected to BmN cells. The budded viruses were collected from the supernatant of the transfected cells and used for infecting BmN cells. Growth curve analysis indicated that BmBacJS13-ph had a similar growth curve to that of wild-type BmNPV. Bio-assays indicated that BmBacJS13-ph was also infectious to B. mori larvae.

OBJECTIVETo establish a novel severe aplastic anemia (SAA) mouse model by interferon-γ (IFN-γ) plus busulphan.
METHODSThirty clean-class BALB/c female mice were intraperitoneally injected with IFN-γ and intragastrically administrated with busulphan (group I), meanwhile busulphan alone group (n = 30, group II) and normal control group (n = 30, group III). Multi-parameters were compared among the three groups.
RESULTSIn group I at day 10 after treatment, the incidence of SAA was 100% and mortality 20% respectively; the WBC, HGB, PLT, absolute reticulocyte count (Ret) and tibial nucleated cell count (TNCC) were (0.8 ± 0.3) × 10(9)/L, (45 ± 20) g/L, (10 ± 8) × 10(9)/L, (15.2 ± 10.2) × 10(9)/L, (12 ± 7) × 10(6)/tibia, respectively, which were significantly different from the other two groups (all P < 0.05). The bone marrow smears and patho-histological examinations showed marked reductions of marrow cell proliferation, and increases of the percentages of non-hematopoietic cells and cellular adipose. The depression was severe and irreversible. In group II, the blood cells count, TNCC and marrow proliferation recovered gradually with erythroid hyperplasia and hematopoietic dysplasia.
CONCLUSIONSIFN-γ plus busulphan can establish a SAA mouse model in a relatively short period, which is more resemble with human SAA.
