OBJECTIVETo investigate the factors influencing the pregnancy outcomes of artificial insemination with donor sperm (AID), improve the pregnancy rate, and evaluate the safety of the offspring.

METHODSWe retrospectively analyzed 7,761 cycles of AID for 5,109 infertile couples performed between July 1, 2005 and June 30, 2013 in the Center of Reproductive Medicine of Shenyang No 204 Hospital, the outcomes of pregnancy, and the incidence of birth defects.

RESULTSTotally, 2 252 clinical pregnancies were achieved by AID, in which the pregnancy rate per cycle was 29. 02% and the cumulative pregnancy rate was 44. 08%. The clinical pregnancy rate was remarkably higher in the females of ≤ 35 years than in those of > 35 years old (30.31% vs 20.18%, P < 0.01), in the women with < 5-year infertility than in those with > 5-year infertility (30.83% vs 28.16%, P < 0.01), and in the patients of the ovarian stimulation group than in those of the natural cycle group (33.22% vs 28.68%, P < 0.01) The clinical pregnancy rate was the highest in the first treatment cycle (29.87%), with statistically significant difference from the fourth cycle (23.61%) (P < 0.05), but not between the other cycles (P > 0.05). There were 28 cases of birth defects in the offspring (1.40%), including 6 cases (21.43%) involving the cardiovascular system, 4 (14.29%) involving the musculoskeletal system, 3 (10.71%) involving the urogenital system, 3 (10.71%) involving the central nervous system, 2 cases (7.14%) of cleft lip and palate, 2 (7.14%) involving the respiratory system, 2 (7.14%) involving the gastrointestinal digestive system, and other anomalies.

CONCLUSIONFemale age, infertility duration, and ovarian stimulation treatment are important factors influencing the clinical pregnancy rate of AID. Artificial insemination with cryopreserved donor sperm does not increase the incidence of birth defects, which is considered as a relatively safe technique of assisted reproduction.

The definition of critical quality attributes of Chinese materia medica ( CMM) was put forward based on the top-level design concept. Nowadays, coupled with the development of rapid analytical science, rapid assessment of critical quality attributes of CMM was firstly carried out, which was the secondary discipline branch of CMM. Taking near infrared (NIR) spectroscopy as an example, which is a rapid analytical technology in pharmaceutical process over the past decade, systematic review is the chemometric parameters in NIR model evaluation. According to the characteristics of complexity of CMM and trace components analysis, a multi-source information fusion strategy of NIR model was developed for assessment of critical quality attributes of CMM. The strategy has provided guideline for NIR reliable analysis in critical quality attributes of CMM.

Objective To investigate protective activity against Aβ25-35-induced cytotoxicity in PC12 cells of different extracts and ursolic acid, which were isolated from pyrola decorata. Methods Aβ25-35-induced cytotoxicity in PC12 cells was established as the model in vitro. The cultured PC12 cells were divided into blank control group, DMSO control group, model control group, different extract groups of pyrola decorate and ursolic acid(UA) group. The different extract groups included ether extract (PE), acetidin extract (AE), n-butanol extract (BE), the water extract (WE), 50% ethanol extract (HEE). MTT assay was used to test the optimum concentration, and the number of viable cells in culture medium was measured by ELISA at 490 nm wavelength. Results The cell viabilities in different extracts groups(PE, AE, BE, WE, HEE) were respectively 89.3%, 77.2%, 79. 2%, 75. 1% ,74. 0% at the concentration of 5. 0 mg ? mL-1 . Moreover, ursolic acid showed the best neuroprotective activity (88.9%) at the concentration of 500 μg?L-1 . Compared with model control group, the survival rate of each group was remarkably increased, and the protective activities of PE and UA were more significant among them. Conclusion Different polar extracts of pyrola decorata and isolated ursolic acid have neuroprotective effects on Aβ25-35-induced cytotoxicity in PC12 cells in certain degrees.

Objective To explore the effects of endoplasmic reticulum stress response(ERS) and its related apoptosis on dopaminergic neurons death.Methods NGF treated-PC12 cells were treated with 6-OHDA,MPP+ and rotenone.MTT assay and flow cytometry were used to measure the cell viability and the rate of cells apoptosis induced by those neurotoxins at different concentrations and times.The expressions of ERS-related gene XBP1,Grp78,CHOP,caspase-12 in drug-treated group and reserpine preincubation group were determined by RT-polymerase chain reaction(RT-PCR) and immunohistochemistry.Results After exposing to different concentration toxins,the vitality of PC12 cells was decreased by 52% at 100?mol/L 6-OHDA,by 44% at 75?mol/L MPP~+,and by 40% at 20 nmol/L rotenone for 24 hours respectively and ws decreased in a dose dependent manner. FCM assay confirmed time-dependent cell apoptosis.The apoptotic cells ratio of 24 h groups were (31.22?3.21)%,(27.46?2.35)%,(29.26?2.53)%,respectively(P＜0.01).In 6-OHDA groups,the gene expressions of XBP1,Grp78 were approximately 2-fold increased after 8 h exposure, CHOP reached peak level at 16 h(149.5?3.3% vs 35.9?1.8%,P＜0.01).The transcription level of caspase-12 was significantly higher than normal control at 16h[(95.4?2.8% vs(23.8?3.0)%, P＜0.01],but was alleviated by reserpine prcincubation(62.15?4.3%,P＜0.05).The increased expressions of Grp78 and CHOP after drug exposure were confirmed by immunochemistry stain.The similar results were observed in MPP~+ and rotenone groups.Conclusions The excessive ERS and ERS-activated cell apoptosis pathway may be involved in selective death of dopaminergic neurons.

OBJECTIVETo compare clinical outcomes of swing shoulder and internal fixation in treating proximal humeral fractures.

METHODSFrom June 2007 to June 2012, totally 89 elderly patients with humeral proximal fractures were treated by swing of shoulder or internal fixation, and 81 patients were followed up. In swing shoulder group, there were 38 patients including 13 males and 25 females aged from 62 to 84 with an average of (67.11±6.18) years old; 27 cases were 2-part fractures and 11 cases were 3-part fractures according to Neer classfication. In internal fixation group, there were 43 patients including 16 males and 27 females aged from 60 to 80 with an average of (66.47±5.48) years old; and 29 cases were 2-part fractures and 14 cases were 3-part fractures according to Neer classfication. VAS score and complications were compared between two groups after treatment, and Constant-Murley functional scoring was used to evaluate shoulder function of patients.

RESULTSEighty-one patients were followed up from 13 to 26 months with an average of 18.3 months. There was no significant difference in preoperative VAS score between two groups. After treatment, VAS score in swing shoulder group was (3.11±0.95), and (3.88±1.14) in internal fixation group, and had significant difference between two groups (t=-3.313,P<0.05). There was no significant difference in Constant-Murley scores between swing shoulder group (79.53±3.73) and internal fixation group (77.98±4.11) (t=1.768,P>0.05). Postoperative complications in swing shoulder group was 18.4%(7/38), 39.5%(17/43) in internal fixation group, and had significant differences between two groups (χ2=4.313,P<0.05).

CONCLUSIONSwing shoulder for the treatment of proximal humeral fractures in elderly has advantages of low cost, less complications and good recovery of joint function; while internal fixation has a good therapeutic effect but increased complications.

Objective To assess the value of 11 C-methionine (MET) PET/CT for the diagnosis of residual or recurrent glioma in comparison to 18 F-FDG PET/CT. Methods Forty-six patients suspected of residual or recurrent glioma underwent both 11 C-MET and 18 F-FDG PET/CT within 5-day interval. The glioma was considered as positive on PET/CT images based on ( 1 ) visual judgment of higher tracer uptake compared with the normal gray matter; (2) semiquantitative analysis of tumor to contralateral normal gray matter (T/G) and contralateral normal white matter (T/W) ratios. The diagnosis was confirmed by stereotsctic biopsy or radiological findings of MRI or CT and clinical follow-up ( ＞6 months). The Chi-square test and paired t test were used for statistical analysis. Results Residual or recurrent glioma was confirmed in 36 patients. The sensitivity, specificity, accuracy of 11C-MET and 18F-FDG PET/CT were 94.4% (34/36) vs 47.2% (17/36), 90.0% (9/10) vs 100% (10/10), 93.5% (43/46) va 58.7% (27/46) (x2 =19. 429, 1. 053, 15. 294, P ＜0.001, ＞0.05, ＜0.001 ), respectively. The T/G and T/W ratios of residual/recurrent giloma by 11 C-MET were significantly higher than those by 18 F-FDG (T/G ratio: 1.68 ± 0.23 vs 1.13 ±0.51, t = 5. 877, P ＜ 0. 001; T/W ratio: 2.52 ± 0.28 vs 1.42 ± 0. 57, t = 10. 470, P ＜0. 001 ). Conclusion 11 C-MET PET/CT is more sensitive and accurate than 18 F-FDG PET/CT for the detection of residual or recurrent glioma.
