Objective To study the effect of exogenous non secreted human urokinase type plasminogen activator(uPA) gene on the production of collagen in activated hepatic stellate cells(HSC) after delivery by replication deficient recombinant adenovirus vector. Methods Non secreted human uPA was inserted into the replication deficient recombinant adenoviruses AduPA in bacteria. After infected by AduPA, the expression of uPA in HSC cell line HSC T6 was detected by Northern blot and immunocytochemical staining, and the level of matrix metalloproteinase 2 (MMP 2) in the supernatant of cultured HSC T6 cells was measured by ELISA. In addition, immunocytofluorescent staining was carried out to evaluate the effect of AduPA on the production of collagen Ⅰ and Ⅲ in HSC after exogenous uPA gene delivery. Results 5?10 11 efu/ml titer of AduPA was obtained in the HSC infected with the recombinated virus. Northern blot and immunocytochemical staining showed that the expression of uPA in HSC increased significantly on the third day after infection with the AduPA. The level of MMP 2 in the supernatant of the cultured HSC was (274.45?7.63) pg/ml, which was higher than that in the control [(145.85?6.58) pg/ml, P

Objective To systematically evaluate the effect of speech and language therapies and educational interventions on chil-dren with intellectual and developmental disabilities(IDD). Methods A systematic review was conducted by searching relevant literature in PubMed,PsycINFO,ERIC,Cochrane Library and Web of Science databases,ranging from January,2018 to May,2024. Results A total of eight English articles were included,from six countries including the United States,France,Italy,Nor-way,Poland and New Zealand,involving 610 children with IDD,from journals about speech language pathology,Down syndrome research and speech language hearing research.The publication time was mainly from 2018 to 2023.The age of the subjects was two to twelve years,and the main health conditions included intellectual dis-ability,autism and Down syndrome.The intervention methods included routine speech therapy(individualized therapy and group therapy),augmentative and alternative communication(device-assisted and sign language and picture cards),family-involved language training programs(parent training and family interaction),computer-as-sisted language learning(language learning software and telehealth),and play-based interventions(interactive games and structured games);15 to 150 minutes a time,one to ten times a week,for ten to 144 weeks.The out-comes were reflected in five aspects:increasing the vocabulary in speaking;improving the language comprehen-sion,symbol recognition and vocabulary comprehension;improving both expressive and receptive language skills;improving participation in game diversity and game participation levels,communication,social interaction and interaction skills;and improving overall language and non-verbal communication skills. Conclusion Combining a variety of methods,such as individualized therapy,family participation,technologic assistance and interactive games,speech and language therapies and education are effective on spoken language production,language comprehension,speech production,social interaction and communication skills for children with IDD.

Objective To compare the clinical efficacy of minimally invasive surgery and traditional surgery in the treatment of multiple benign mammary lumps.Methods A retrospective study was conducted to select 158 patients with multiple benign breast masses admitted to Yijishan Hospital of Wannan Medical College from July 2016 to February 2018,all of them were female,average age was (28.3 ± 6.6) years old,range from 19 to 51 years old.The patients were divided into minimally invasive group (n =122) and traditional group (n =36) according to different surgical methods.The minimally invasive group was treated by minimally invasive rotary excision,while the traditional group was treated by traditional surgery.The operation time,number of incisions,average length of incisions,cumulative length of incisions and healing time of incisions were compared between the two groups.The incidence of local hematoma,local infection,breast deformity and local residual were compared after operation,and the satisfaction of the two groups was aslo compared.Normal distribution measurements were expressed by mean ± standard deviation (Mean ± SD),independent sample t test was used for inter-group comparison;non-normal distribution measurements were expressed by median (quartile spacing) [M(P25,P75)],Mann-Whitney U test was used for inter-group comparison.Chi-square test or Fisher exact probability test was used to compare the count data between the two groups.Results As compared to the traditional group,the minimally invasive group had shorter operation time (20.0 min vs 40.0 min,Z =-8.590,P < 0.001),less number of incisions (1.0 vs 2.0,Z =-4.423,P <0.001),smaller average surgical incision length (3.8 mm vs 35.5 mm,Z =-9.211,P < 0.001),smaller cumulative surgical incision length (4.0 mm vs 67.2 mm,Z =-9.130,P < 0.001),quicker postoperative recovery (4.0 d vs 7.0 d,Z =-9.334,P < 0.001).There were no significant differences between the two groups in incidence of postoperative hematoma (4.1% vs 2.8%,x2 =0.000,P =1.000),incidence of infection (0 vs 2.8%,P =0.228),incidence of postoperative breast shape change (1.6% vs 2.8%,x2 =0.000,P =1.000),and incidence of residual (0.8% vs 0,P =1.000).Psychological satisfaction of patients in minimally invasive group (95.1%) was significantly higher than that in traditional group (58.3%),the difference was statistically significant (P < 0.001).Conclusions Compared with traditional surgery,the application of minimally invasive surgery in the treatment of multiple benign mammary lumps has many advantages,such as shorter operation time,less number of incisions,smaller surgical incision length,quicker postoperative recovery and higher satisfaction of patients after operation.It has not significantly increased postoperative complications.It is worthy of clinical application and promotion.
