Objective:To explore the effectiveness, safety and cost between urinary follicle stimulating hormone (uFSH) and recombinant follicle stimulating hormone (rFSH) in controlled ovarian stimulation (COS) in China.Methods:Data were collected from 16 reproductive centers in China covering oocytes collection time from May 1, 2015 to June 30, 2018. Eligible patients were over 18 years old, adopting COS with uFSH (uFSH group) or rFSH (rFSH group) as start gonadotropins (Gn), and using in vitro fertilization (IVF) and (or) intracytoplasmic sperm injection for fertilisation, excluding frozen embryo recovery cycle. Generalised estimating equation was used to address the violation of independency assumption between cycles due to multiple IVF cycles for one person and clustering nature of cycles carried out within one center. Controlling variables included age, body mass index, anti-Müllerian hormone level, cause of infertility, ovulation protocol, type of fertilisation, number of embryos transferred, number of days of Gn use.Results:Totally 102 061 cycles met eligibility criteria and were included in the analyses. In terms of effectiveness, after controlling relevant unbalanced baseline characteristics, compared with rFSH group, the high oocyte retrieval (>15 oocytes was considered high retrieval) rate of uFSH group significantly decreased in gonadotropin-releasing hormone agonist protocol ( OR=0.642, P<0.01) and in gonadotropin-releasing hormone antagonist protocol ( OR=0.556, P=0.001), but the clinical pregnancy rate per transfer cycle and the live birth rate per transfer cycle significantly increased ( OR=1.179, OR=1.169, both P<0.01) in both agonist and antagonist protocols. For safety, multiple analysis result demonstrated that in the agonist protocol, compared with rFSH group, the incidence of moderate to severe ovarian hyperstimulation syndrome of uFSH group significantly decreased ( OR=0.644, P=0.002). The differences in ectopic pregnancy rate and multiple pregnancy rate between the uFSH and rFSH groups were not significant ( P=0.890, P=0.470) in all patients. In terms of cost, compared with rFSH group, the uFSH group had lower total Gn costs for each patient ( P<0.01). Conclusion:For patients who underwent COS, uFSH has better safety, and economic profiles over rFSH in China.

BACKGROUND AND OBJECTIVES: The International Society for Cellular Therapy (ISCT) proposed a set of minimal markers for identifying human mesenchymal stromal cells (hMSCs) in 2007. Since then, with the growing interest of better characterising hMSCs, various additional surface markers have been proposed. However, the impact of how culture conditions, in particular, the culture surface, vary the expression of hMSC markers was overlooked. METHODS AND RESULTS: In this study, we utilized the RNA sequencing data on hMSCs cultured on different surfaces to investigate the variation of the proposed hMSC biomarkers. One of the three ISCT proposed positive biomarker, CD90 was found to be significantly down regulated on hMSCs culture on fibrous surfaces when compared to flat surfaces. The detected gene expression values for 177 hMSCs biomarkers compiled from the literature are reported here. Correlation and cluster analysis revealed the existence of different biomarker communities that displayed a similar expression profile. We found a list of hMSCs biomarkers which are the least sensitive to a change in surface properties and another list of biomarkers which are found to have high sensitivity to a change in surface properties. CONCLUSIONS: This study demonstrated that substrate properties have paramount effect on altering the expressions of hMSCs biomarkers and the proposed list of substrate-stable and substrate-sensitive biomarkers would better assist in the population characterisation. However, proteomic level analysis would be essential to confirm the observations noted.

Objective To understand the correlation between health beliefs and family environment of stroke patients. Methods A questionnaire survey was carried out on 115 stroke patients with the first onset of stroke by using the special health belief simple table (SF-HBMS) and the family environment scale (Chinese version FES-CV), and the correlation was analyzed. The scores of each subscale of the family environment were compared with the domestic norm. Results The total score of health belief (75.15 ± 10.20) was at the middle level. There were significant differences in age (F=8.41), education level (F=4.44), complications (F=4.05), family history (t=2.68) and first visit time (F=3.76) among different characteristics of health belief scores (P < 0.01 or 0.05). The score of intimacy (6.23 ± 1.27) in family environment, emotional expression score (5.30 ± 1.97), success score (5.88 ±1.62), cultural score (4.54 ± 2.20) and organizational score (5.60 ±1.67) were all lower than the domestic norm and spear. The score of shield score (3.16 ± 2.00) was higher than that of domestic norm (P<0.01 or 0.05), and the total score of health belief was positively correlated with family intimacy (r=0.190), emotional expression (r=0.204), culture (r=0.206) and tissue (r=0.227) (P<0.05), and was negatively correlated with the contradiction (r=-0.186, P<0.05); regression analysis, whether there were family history (β=0.338, P<0.01), first onset time (β=0.242, P<0.01), family intimacy (β=1.614, P<0.05), emotional expression (β=1.114, P<0.05) were the factors affecting the health belief level of first stroke patients. Conclusions The level of health belief is closely related to family environment. It is suggested that the clinical medical staff should pay attention to the negative emotion and family psychological intervention, provide psychological support for the patients and their families, promote the promotion of their health beliefs, and reduce the rate of recurrence and disability.

Objective: To observe the clinical effects of recombinant human growth hormone (rhGH) on children with severe burn. Methods: Clinical data of 94 children with severe burn, hospitalized in our burn unit from April 2012 to December 2016, conforming to the study criteria, were retrospectively analyzed. According to the use of rhGH, children were divided into rhGH group (n=50) and control group (n=44). Children in control group received conventional treatment, while children in rhGH group received both conventional and rhGH treatment. The rhGH treatment was started 3 to 5 days post injury in dosage of 0.2-0.4 U·kg^-1·d^-1, by way of subcutaneous injection, and the course of treatment was (11±5) d. The plasma albumin and prealbumin levels, heart rate, alanine aminotransferase (ALT), and serum creatinine level in 2 weeks post injury, times of skin grafting operation, hospitalization time, total hospitalization treatment cost, and sepsis and death of children were compared between the 2 groups. Data were processed with independent sample t test, Mann-Whitney U test, and Fisher′s exact test. Results: (1) In 2 weeks post injury, the plasma albumin level [(36±4) g/L] and prealbumin level [(94±34) g/L] of children in rhGH group were significantly higher than those in control group [(33±4) and (73±20) g/L, t=3.666, 3.401, P<0.05]. (2) In 2 weeks post injury, the heart rate of children in rhGH group was (123±11) times per minute, which was slower than (130±14) times per minute of children in control group (t=2.839, P<0.05). There was no significant difference in ALT level of children between the 2 groups (Z=0.868, P>0.05). The blood creatinine levels of children in the 2 groups were within normal range. (3) The times of skin grafting operation of children in rhGH group was 0.3±0.5, which was significantly less than 0.5±0.6 in control group (Z=2.234, P<0.05). The hospitalization time of children in rhGH group was (22±8) days, which was shorter than (28±10) days in control group (t=2.837, P<0.05). The total hospitalization treatment cost of children in rhGH group was (41±15) thousand yuan, which was significantly less than (53±25) thousand yuan in control group (t=2.878, P<0.05). (4) There were 2 cases of sepsis in control group and 1 case of sepsis in rhGH group, with no significant difference between the 2 groups (P>0.05). No children died in the 2 groups. Conclusions rhGH treatment of children with severe burn can correct post-injury hypoproteinemia, improve cardiac function, reduce the times of skin grafting operation and hospitalization treatment cost, shorten hospitalization time, with no significant effect on kidney and liver function, sepsis, and death.

Objective To observe the curative effect of clinically equivalent doses of Xuesaitong and ginaton injections on cerebral ischemia reperfusion (I/R) injury of rats.Methods Male rats were randomly divided into five groups:normal control group,sham-operation group,model control group,Xuesaitong group and ginaton group.The cerebral ischemia rat model was established by middle cerebral artery occlusion (MCAO).Rats in the Xuesaitong group were given 20 mg·kg-1 of Xuesaitong injection,and rats in the ginaton group were intravenously injected with 7.5 mg· kg-1of ginaton immediately after I/R injury and once daily for 7 days.Rats in the sham-operation group and model control group were given the same volume of 0.9％ sodium chloride solution.The score of ethology,volume of cerebral infarction,mortality,superoxide dismutase (SOD),malondialdehyde (MDA),xanthine oxidase (XOD),nitrogen oxide (NO) and NO synthase (NOS) in seruu were examined.Results Compared with model control group,Xuesaitong and ginaton effectively reduced behavioral score 96 h (P ＜ 0.05),120 h (P＜0.01),144 h (P＜0.01) and 168 h (P＜0.01) after I/R injury,the volume of cerebral infarction 168 h after I/R injury and NO content (P ＜ 0.05).But they had no effects on NOS,SOD,MDA,and XOD contents.Conclusion Curatively injecting Xuesaitong and ginaton can effectively reduce cerebral I/R injury,but no significant difference in curative efficacy is observed between Xuesaitong and ginaton at clinically equivalent doses.

Objective: To explore differential expression of microRNAs in serum of patients with severe burn and analysis of the signaling pathway at early stage. Methods: In this study, we included three healthy adult volunteers and three patients with severe burn, conforming to the inclusion criteria and hospitalized in Tongren Hospital of Wuhan University & Wuhan Third Hospital in July 2015. Venous whole blood of 6 mL of each burn patient and healthy volunteer was collected at 24 to 48 h post injury of burn patients. The whole blood was divided into burn group and healthy control group. Whole blood of 2 mL of each one was used to determine white blood cell count and neutrophile granulocyte content. Serum was separated from the other whole blood of 4 mL of each one. Half of serum was used to determine content of blood glucose, total protein, and albumin; another half of serum was used to extract total RNA with Trizol method. The differentially expressed microRNA, with differential expression ratio larger than or equal to 1.500 between 2 groups, were screened by microRNA chip technique. Then cluster analysis and functional enrichment analysis of Kyoto encyclopedia of genes and genomes (KEGG) signaling pathway were performed on the differentially expressed microRNAs. Data were processed with t test. Results: (1) Content of white blood cell count, neutrophile granulocyte of whole blood, and blood glucose of serum of patients in burn group was obviously higher than that in healthy control group (with t values from 4.27 to 7.83, P<0.05 or P<0.01). Content of total protein and albumin of serum of patients in burn group was significantly lower than that in healthy control group (with t values respectively -12.80 and -12.36, P values below 0.01). (2)Compared with those in serum of healthy control group, differential expression ratios of 48 microRNAs in serum of burn group were larger than 1.500, with 22 up-regulated microRNAs and 26 down-regulated microRNAs. MicroRNA expression profile in serum of burn group was different from that of healthy control group. (3)Functional enrichment analysis of KEGG signaling pathway showed that compared with those in serum of healthy control group, microRNAs of differential expression in serum of burn group took part in tumor transcription misregulation signaling pathway, tumor proteoglycan signaling pathway, long-term potentiation signaling pathway, tumor associated microRNAs signaling pathway, citrate cycle signaling pathway, tumor necrosis factor signaling pathway, focal adhesion signaling pathway, endocytosis signaling pathway, insulin secretion signaling pathway, and estrogen signaling pathway. Conclusions MicroRNA expression profile in serum of patients with severe burn is different from that in serum of healthy adults. MicroRNAs of differential expression may take part in important pathophysiological process of energy metabolism, inflammatory response, and regulation of blood glucose at early stage of severe burn.

Objective To investigate effects of disease cognitive education and behavior intervention on acute testicular torsion of adolescents. Methods A total of 100 cases with acute adolescent testicular torsion were randomly divided into observation group and control group, and 50 cases in each group. The patients in control group received conventional health education, while patients in observation group were administrated cognitive psychology education and behavioral intervention. We scored health education on testicular torsion knowledge by applying self-made cognitive questionnaire, and then compared the differences of adverse events and compliance of health education between two groups. Results The scores of health education and health compliance on adolescent testicular torsion disease were (95. 65 ± 10. 35) and (80. 30 ± 16. 30) in observation group, while they were (58.15 ±16.85) and (73. 70 ± 17. 20) in control group (t =20. 386, 4. 184; P <0. 05). There was no postoperative incision infection and testicular atrophy in observation group. However, there was 15 incision infection and 10 testicular atrophy in control group (χ2 =14. 326, 10. 358; P<0. 05). Conclusions Public education on testicular torsion knowledge can contribute adolescent patients to be aware of the dangers of testicular torsion, give importance to treatment timing, and increase the rate of early diagnosis and treatment.

Objective To assess the dignosis value of CT three-dimensional reconstruction with Fisher discriminant model in small solitary pulmonary nodules before operation.Methods CT data of 40 cases with SPN were retrospectively analyzed and divided into into malignant pulmonary nodules (25 cases),squamous cell carcinoma (4 cases),adenocarcinoma (13 cases),lung cancer (4 ca-ses),small cell lung cancer (2 cases),large cell carcinoma (1 case),metastases tumor (1 case),benign nodules (1 5 cases,6 cases of tuberculosis,2 cases of hamartoma,and 7 cases of non-specific inflammatory nodules)by pathology and follow-up results.The CT features of pulmonary nodules were evaluated through multi-planar reformation (MPR),curved-planar reformation (CPR),volume rendering (VR),maximum intensity proj ection (MIP)and other three-dimensional reconstruction.The three-dimensional data were divided into benign and malignant groups.In each of the two groups,the significant signs of morphological signs of discrimination indicators were adminstrated Fisher discriminant,and the probalitiy of false positives were estimated using cross-validation method. Results The positive features of pulmonary nodules in there-dismensional images were much more than in two-dimensional images. Fisher discriminant formula of solitary pulmonary nodules in three-dimensional images was Z=1.143X1 + 0.454X2+1.606X3-0.262X4+0.04X5+0.483X6+1.611X7-2.164.Discriminant boundary value Zc was-0.516.When Zcgreater than -0.516,nodules were proneed to considere as malignant nodules.In 25 cases of malignant nodules,4 cases mistook for benign.When Zc less than -0.516,nodules were proneed to considere as benign nod-ules.In 1 5 benign nodules,2 cases mistook for malignant.The total misdiagnosis and accuracy rate were 15 % and 85% respec-tively.Conclusion CT three-dimensional reconstruction combined with Fisher discriminant model have a high clinical value in dif-fereiating diagonsis of pulmonary nodules were proneed to considere as malignant nodules.In 25 cases of malignant nodules,4 cases mistook for benign.When Zc less than -0.516,nodules were proneed to considere as benign nodules. In 15 benign nodules,2 cases mistook for malignant.The total misdiagnosis and accuracy rate were 15 % and 85% respec-tively.Conclusion CT three-dimensional reconstruction combined with Fisher discriminant model have a high clinical value in differeiating diagonsis of pulmonary nodules.

Objective To investigate the expression changes of microRNAs and VEGF-NOTCH in renal ischemic injury in mice, and to explore the potential mechanism associated with renal angiogenesis.Method Male Balb/c mice were subjected to a standard renal ischemia to induce acute kidney injury (AKI) after 45 min of bilateral renal artery clamping. Following 4 h, 24 h of reperfusion or sham operation, kindey tissues were collected and subjected to detect the expression changes of microRNAs which relatived with angiogenesis and VEGF, Flk-1, Notch1 mRNA by Quantitative Real-time RT-PCR. Flk-1 protein was detected by Western blotting analysis at 24 h and 72 h following Ischemia/Reperfusion(I/R) injury. The expression of CD31 was examined in tissue sections by immunohistochemistry staining, and the microvessels in ischemic region of each group were counted. Results miRNA-210 and miRNA-92a expression increased significantly, with prominent changes at 4 h and 24 h after reperfusion( P ＜ 0.05 ). VEGF and Flk-1 mRNA expression and Flk-1 protein were increased in renal I/R compared with control group respectively (P＜0.05 ).Immunohistochemistry staining results of CD31 showed a significant increase of microvessels in renal ischemic region. Conclusion This study first reported the changes in miRNAs expression in response to kidney I/R in mouse. our results implied that miRNAs may be involved in targeting VEGF-Notch pathway signaling to regulate angiogenesis after renal I/R injury. It provided novel insights into the angiogenesis mechanism of renal ischemic injury.
