Objective:To establish the technique for real-time fluorescence quantitative reverse transcription polymerase chain reaction(FQ-PCR)by DNA melting curve analysis for detecting the CDR3 shewing of TCR alpha gene repertoire in human peripheral blood.Methods:Total RNA of peripheral blood mononuclear cell(PBMC)from 4 healthy donors and 2 patients with lymphomatous leukemia were transcripted reversely into cDNA.The cDNA of 32 TRAV gene family CDR3 was amplified by FQ-PCR.Analysis of the monoclonal/oligoclonal/polyclonal CDR3 spectratyping with DNA melting curve.Results:The FQ-PCR products of 32 TRAV family CDR3 were showedas a blur land at the predicted of products size in healthy donors and parts of TRAV family CDR3 products disappeared in patients on 1.5% agarose gel by Gold-View staining.The 32 TRAV family CDR3 were showed with different frequencies by relative fluorescence quantitative in healthy donors and the patients.The CDR3 spetratyping for 32 TRAV families was showed as polyclonal peak(Gaussian distribution)in healthy donors but showed as different monoclonal/oligoclonal/polyclonal peak in the patients with lymphomatous leukemia with DNA melting curve analysis(we called "melting curve spectratyping of CDR3")Conclusion:The study suggests that the technique of "FQ-PCR with DNA melting curve analysis be convenience and celerity for detecting the CDR3 skewing of TCR alpha gene repertoire in human peripheral blood.

ObjectiveTo assess the effects of constraint-induced movement therapy(CIMT) on sub-acute stroke patients with upper extremity motor dysfunction.Methods63 patients with hemiplegia after stroke were divided into two groups: control group(31 cases) and CIMT group(32 casese). The two groups received the regular rehabilitation training for 14 d. Then the control group went on the the regular rehabilitation training, while the CIMT group received CIMT for 14 d. All patients were assessed by the Action Research Arm Test(ARAT) and Fugl-Meyer(FMA) on the first day, the 15th day and the 30th day after the treatment.ResultsARAT score and FMA scores were higher in CIMT group than in the control group 30 d after the treatment and in CIMT group 15 days after the treatment(P<0.001).ConclusionCIMT is more effective to improve the upper limb motor function of the sub-acute stroke patients than the regular rehabilitation training.

Objective: To discuss the surgical method and clinical effect of applying the facial artery perforator-based nasolabial para-nasal advanced flap to repair the medial canthus and inner lower eyelid skin defects. Methods: The advance nasolabial para-nasal perforator flap supplied by facial artery, was used to repair the medial canthus and inner lower eyelid skin defects, caused by dermatoma excision. Results: All 18 flaps completely survived. The detects in the medial canthus andinner lower eyelid, and the donor sites in the nasolabial fold were primary healed.The medial canthus and inner lower eyelid were recovery satisfactorily.The flaps were not bloated, and the contour and texture of flaps were similar to adjacent tissue, with no need of secondary repair.The donor site was successfully hidden in the nasolabial dermatoglyph. Conclusions Nasolabial para-nasal perforator flap is easily obtained, reliable in blood supply, and flexible in transfer. It has a wide range of movement and is easy to advance, so as to repair medial canthus andinner lower eyelid defect. With above advantages, this flap is worthy towidely popularize.

Objective:To investigate the efficacy, safety and recurrence rate of oral atenolol in the treatment of infantile hemangioma, so as to provide evidence-based medicine basis and reference for clinic.Methods:Search on the following public databases from January 1, 2008 to June 13, 2022: Web of Science, PubMed, Cochrane Library, Embase, U. S. National Library of Medicine Clinical Trials Registry Platform; China National Knowledge Infrastructure(CNKI), Chinese Biomedical Literature Service System(SinoMed), Chinese Science and Technology Journal Database and Wanfang Data. According to inclusion and exclusion criteria, studies on oral atenolol for the treatment of infantile hemangioma were selected. The outcome indicators were efficiency (complete response rate), incidence of adverse effects and recurrence rate. The single-arm meta-analysis was performed using R software version 4.1.2. Egger’s test was employed and funnel plots were drawn to assess publication bias in the literature.Results:A total of 14 studies were included, comprising 5 randomized controlled trials, 5 single-arm studies, 3 non-randomized controlled trials, and 1 case-control study. The oral administration of atenolol for the treatment of infantile hemangiomas resulted in an efficacy rate (complete remission rate) of 62% (95% CI 52%~71%). The incidence rate of adverse reactions related to the digestive system was 18% (95% CI 7%~30%), while that related to β2 receptor blockade was 4% (95% CI 2%~6%), central nervous system-related adverse reactions occurred at a rate of 10% (95% CI 5%~16%), the recurrence rate was 5% (95% CI 2%~9%). Egger’s test indicated that there was no significant publication bias in the efficacy rate, central nervous system-related adverse reaction rate, and gastrointestinal-related adverse reaction rate of oral atenolol treatment for infantile hemangiomas ( P>0.05). The sensitivity analysis for the efficacy rate, adverse reaction rate, and recurrence rate of oral atenolol treatment for infantile hemangiomas suggested that the result were stable and reliable. Conclusion:Oral administration of atenolol for the treatment of infantile hemangiomas demonstrates significant efficacy, fewer adverse reactions, and a low recurrence rate, making it a promising candidate as a reasonable alternative to oral propranolol for treating infantile hemangiomas.

Objective To explore the effects of "3+1+1" talent cultivation model on key competency in five-year higher vocational nursing students. Methods In March 2015, we selected five-year 80 higher vocational nursing students majoring in clinical nursing in 2013 of Wuxi Higher Health Vocational Technology School as subjects by convenience sampling. All of the 80 nursing students were divided into experimental group (n=38) and control group (n=42) according to classes. Nursing students of experimental group received the "3+1+1" talent cultivation model. Nursing students of control group were treated with the "4+1" cultivation model. The evaluation index system for key competency of five-year higher vocational nursing students was used to evaluated nursing students of two groups. We also compared the theoretical achievement and skills performance of nursing students between two groups. Results There were no statistical difference in key competency of nursing students between two groups at the end of the 2.5th school year (P＞0.05). The score of key competency of nursing students in experimental group was higher than that in control group at the end of the fourth school year with a significant difference (P＜ 0.05). There were no statistical differences in theoretical achievement and skills performance of nursing students between two groups at the end of the 2.5th school year (P＞0.05). The theoretical achievement and skills performance of nursing students in experimental group were higher than that in control group at the end of the fourth school year with significant differences (P＜ 0.05). Conclusions The "3+1+1" talent cultivation model can improve nursing students' key competency and school achievement.
