Objective To explore ICSI treatment process in the different proportion of oocytes maturation and dosage of gonadotropin affecting embryo quality and clinical outcome. Methods From Jan. to Dec. 2015,we retrospectively analyzed the patients from the center line of ICSI cycle ,divided them into three groups according to the maturity of oocytes. The 3 groups were due to maturity rate of oocytes in 50% in group A(n = 19),50% 0.05). Group A had the best egg rate,high quality embryo rate,clinical pregnancy rate than the other two groups (P < 0.05). In pregnancy and non-pregnancy groups ,the dosage of gonadotropin in the non-pregnancy group was obviously higher than that in the pregnancy group in oocyte maturation in the same proportion interval(P<0.05). Conclusion In ICSI treatment process,the high dose of gonadotropin and rising rates of oocytes maturation are not conducive to the development potential of the egg and clinical outcome,so the dose of gonadotropin and oocyte maturation ratio should be controlled in a certain range to collect and protect the best dominant egg which matches to the state of the patient.

Objective To get TDRP1 gene of sterile and fertile boar of the Banna minipig inbred line (BMI), predict its function by bioinformatics analysis, and detect its expression patterns in the fertile boar.Methods Based on the NM_001198925 sequence, we designed specific primers and amplified BMI TDRP1 using RT-PCR method for sequen-cing and bioinformatics analysis.Meanwhile, the expression of TDRP1 in 17 organ tissues ( heart, liver, spleen, lung, kidney, thymus, lymph nodes, skin, duodenum, stomach, cerebrum, cerebellum, testis, epididymis, seminal vesicle, prostate, and bulbourethral gland) of fertile BMI boar and in the testis of sterile and fertile BMI boars was analyzed by semi-quantitative RT-PCR.Results The experiment obtained 680 bp cDNA sequence ( GenBank accession number:KJ186786) of BMI TDRP1, which encodes a protein of 186 amino acids with a predicted molecular weight (Mw) of 20.49 kDa and isoelectric point (pI) 5.86, and no signal peptide.It was a nuclear protein with a probability of 94.1%and had a leucine-rich nuclear export signals.Homology analysis of protein sequences revealed that BMI TDRP1 showed high identi-ty with that of humans, macaca mulatta, mouse and rat.The RT-PCR analysis showed that TDRP1 had a similar expression in the testes of sterile and fertile BMI boars.It was highly abundant in the seminal vesicle and prostate, moderately ex-pressed in cerebellum and testis and weakly expressed in cerebrum and kidney, while undetected in other 11 organ tissues. Conclusions We have cloned TDRP1 complete coding sequence, and found 2 SNPs,showing no difference in sequences and the testis mRNA expression levels between the fertile and sterile BMI boars.The multi-tissue transcription profile shows different expression levels in different organ tissues, being high in the seminal vesicle and prostate.The results of this study provide a foundation for further insight into the role of this gene in spermatogenesis.

Objective: To systematically evaluate the efficacy and safety of CT-guided percutaneous lung puncture biopsy versus ultrasound-guided percutaneous lung puncture biopsy. Methods: Relevant domestic and foreign related databases such as PubMed, Web of Science, Cochrane Library, OVID, China Biology Medicine, VIP, Wanfang and CNKI databases were searched, the randomized controlled trial about the applications of CT-guided and ultrasound-guided percutaneous lung puncture biopsy were collected. After extracting the relevant data, a Meta-analysis was performed using RevMan 5.2 and Stata softwares. Results: Ten studies met the inclusion criteria, with a total sample size of 1 158 cases, of which 635 were CT-guided puncture biopsy and 523 were ultrasound-guided puncture biopsy. Meta-analysis showed that the difference of the success rate between the CT-guided group and the ultrasound-guided group was not statistically significant [97.48% (619/635) vs. 96.56% (505/523), RR= 1.01, 95% CI 0.99-1.03, P= 0.360]; the puncture diagnosis rate in the CT-guided group was lower than in the ultrasound-guided group, and the difference was statistically significant [92.44% (619/635) vs. 96.56% (505/523), RR= 0.97, 95% CI 0.94-0.99, P= 0.007]. The total incidence of complications after puncture in the CT-guided group was higher than that in the ultrasound-guided group, and the difference was statistically significant [14.49% (92/635) vs. 9.56% (50/523), RR= 1.56, 95% CI 1.11-2.19, P= 0.010]; the incidence of pneumothorax after puncture in the CT-guided group was higher than that in the ultrasound-guided group, and the difference was statistically significant [11.50%(73/635) vs. 6.31% (33/523), RR= 1.77, 95% CI 1.17-2.68, P= 0.007]; the difference of the incidence of bleeding after puncture between the CT-guided group and the ultrasound-guided group was not statistically significant [2.99% (19/635) vs. 3.25% (17/523), RR= 1.08, 95% CI 0.59-1.98, P= 0.800]. Conclusions Both CT-guided and ultrasound-guided percutaneous lung puncture biopsy have good clinical diagnostic value. However, for the intrapulmonary masses shown by ultrasound, the ultrasound-guided lung puncture biopsy has a shorter operation time, lower cost, and higher safety.

Objective:To retrospectively analyze the blood leukocytes (WBC), lymphocytes (LYM), lymphocyte% (LYM%), and serum total immunoglobulin (IGA, IGG, IGM) and complement (C3, C4) index levels to explore its predictive value for the outcome of COVID-19 severe pneumonia.Methods:Eighty-five COVID-19 patients with severe pneumonia diagnosed in our hospital were randomly selected and were divided into good outcome group (50 cases) and poor outcome group (35 cases). WBC, LYM, LYM%, IGA, IGG, IGM, and C3, C4 level data, and analyze the differences between the two groups, the correlation of each indicator, and ROC curves of single and joint detection to explore relationship between indicators and outcomes, and the predictive efficacy of indicators on outcomes.Results:Differences in WBC, LYM, LYM%, IGG, and IGA levels were significant between the two groups ( P=0.000, 0.015, 0.000, 0.000, 0.001), among them with significant differences, LYM and LYM% were significantly positively correlated ( r=0.669, P=0.000), while WBC and LYM% levels were significantly negatively correlated ( r=-0.600, P=0.000), WBC and IGA levels were significantly positively correlated ( r=0.283, P=0.009) and IGG and IGA levels were also significantly positively correlated ( r=0.0.442, P=0.000); After logistic regression analysis, WBC, LYM, LYM%, IGG, and IGA are all important influencing factors ( P=0.001, 0.022, 0.000, 0.000, 0.003); but only the levels of WBC, IGG, and LYM% are Independent risk factors ( P=0.034, 0.004, 0.001), the ROC curve of the single detection and joint detection of their predicted outcome performance, respectively, and the max AUC (AUC=0.890, P=0.000) at the time of joint testing of WBC, LYM% and IGG, index YI=0.657, it has the greatest predictive power for adverse outcomes, with a sensitivity of 77.10% and a specificity of 88.00%. IGM, C3, C4, IGG/IGM, and C3/C4 levels were not significantly different( P=0.066, 0.204, 0.076, 0.310, 0.156). Conclusions:The levels of WBC, LYM, LYM%, IGG, and IGA in the early admission of COVID-19 infected patients with severe pneumonia have important predictive value for the outcome of them. WBC, LYM% and IGG levels are independent risks and joint detection of the three indexes have the best predictive performance.
