Objective To investigate the effects of group teaching in rehabilitation nursing. Methods 55 nursing students were dividedinto control group and experiment group. The control group received traditional teaching and the experiment group received group teaching.Questionnaire and examination performance were used to evaluate the effects of group teaching in the teaching of rehabilitation nursing. ResultsThe scores were significantly higher in the experiment group than in the control group (P<0.01). The questionnaire showed that groupteaching can stimulate their interest and intrinsic motivation for learning, enhance their understanding and application of knowledge, cultivatetheir self-learning ability, analysis and problem-solving abilities, interpersonal communication skills and spirit of collaboration. At thesame time, the implementation of group teaching helps both teaching and learning. Conclusion Group teaching can improve the teaching effectivenessof rehabilitation nursing.

Objective To obtain a strain of glycoengineering yeast with higher N-glycosylation efficiency by overexpressing N-glycosyltransferase.Methods Through the selecting marker URA3 gene, a new glycoengineering yeast strain named 4-32-STT3D was constructed, which could overexpress the Leishmania major N-glycosyltransferase staurosporine and temperature sensitivity3 D subunit(STT3D) under the control of an inducible alcohol oxidase 1(AOX1) promoter.We analyzed the N-glycosylation status of anti-human epidermal growth factor receptor 2 ( HER2 ) antibody and granulocyte macrophage colony stimulating factor (GM-CSF) expressed in 4-32-STT3D using SDS-PAGE,Western blotting and peptide-N-asparigineamidase F(PNGase F).Finally the effect of STT3D on the growth rate of glycoengineering yeast was detected.Results SDS-PAGE showed that anti-HER2 antibody expressed in 4-32-HL had two components:the first one with a relative molecular mass 55 ×103 was glycosylated,while the second one with 50 ×103 was non-glycosylated,but anti-HER2 antibody expressed in 4-32-HL-STT3D had the component of 55 ×103 only without any non-glycosylated 50 ×103 .The above components became 50 ×103 with the digestion of PNGaseF.All of them proved to be antibodies by Western blotting.As a report protein,GM-CSF expressed in 4-32-GM-CSF had two components: 22 ×103 and 20 ×103, while in 4-32-GM-CSF-STT3D there was only one with 22 ×103 .All these components became 18 ×103 with the digestion of PNGase F.Statistical analysis showed that without induction,STT3D had no effect on the growth rate of glycoengineering yeast, while great effect was observed when STT3D was induced.Conclusion Glycoengineering yeast with the overexpression of N-glycosyltransferase has higher N-glycosylation efficiency.

Severe community acquired pneumonia (SCAP) has raised substantial concern due to high morbidity and mortality. SCAP is usually associated with multiple organ dysfunction syndrome (MODS) and sepsis. It is suggested that organ function and coagulation/fibrinolysis improvement, organ injury reduction and organ repair facilitation are highly required besides microbiology detection and optimization of antibiotics strategy on treatment of SCAP. Neutralization antibody, steroid, immunmodulatory therapy, and Chinese medicine etc. contribute to organ function improvement from different perspective. The unique profile of multiple target and personalized therapy of Chinese medicine may become a promising new option for SCAP and MODS. The combination of Western and Chinese Medicine shed new light on SCAP treatment.

Objective:To analyze the failure causes and repair methods of conjoint fascial sheath (CFS) suspension in ptosis correction.Methods:From 2021 September to September 2022, 13 cases (5 males and 8 females, aged from 19 to 49 years with an average of 25 years) were collected, and there were 18 eyes of CFS suspension in the Department of Burn and Plastic Surgery Center, the 940th Hospital of the Joint Logistic Support Force of PLA with a failed ptosis surgeries, including levator palpebrae superioris muscle shortening, CFS suspension, and frontalis muscle suspension.Results:Among the 13 patients (18 eyes), the failure causes included a result of the unfamiliar anatomy of CFS, unstable suture fixation, dysplasia of CFS, and improper suture site, CFS suspension failed to correct ptosis. After following-up for 6 to 30 months after reconstructive surgery, 14 eyes were corrected satisfactorily, 2 eyes were relieved of ptosis, and 2 eyes had ptosis recured six months after restorative surgery and a frontalis muscle suspension was used in the recured cases with a satisfactory outcome.Conclusions:According to the patient′s eye condition, mastering the indications, be familiar with the local anatomy and accurate surgical procedures are the key to success.

OBJECTIVETo explore the expression levels of terminal complement complex (C5b-9) and CD62p on platelets and the soluble C5b-9 (sC5b-9) level in serum in patients with PNH or PNH-aplastic anemia (AA).

METHODSSerum levels of sC5b-9, complement C3 and C4 were detected by using ELISA in 25 patients with PNH/PNH-AA. The quantities of C5b-9 and CD62p on the membrane of platelets were detected by flow cytometry.

RESULTS①In PNH/PNH-AA group, the serum sC5b-9 level [390.27(265.73-676.87) μg/L] was lower than that in control group [540.39(344.20-1 576.78) μg/L] (P<0.01). ②The platelet PNH clone (CD59⁻CD61⁺/CD61⁺) size [50.58(23.29-81.60)%] was bigger in the PNH/PNH-AA group than that [23.57(15.58-29.02)%] in control group (P<0.01). The percentages of C5b-9 deposition (C5b-9⁺CD61⁺/CD61⁺) were higher on the PNH clone platelets (CD59⁻CD61⁺) in the PNH/PNH-AA group [(17.53 ± 6.27)%] than those on the normal platelets (CD59⁺CD61⁺) in PNH patients 11.33±5.03）%］ and control [(10.88±3.58)%] group (P<0.01). ③ The expression of CD62p (CD62p⁺CD61⁺/CD61⁺) on PNH clone platelets in PNH patients [(61.98 ± 11.71)%] was higher than that on the normal platelets in PNH patients [(43.76±11.30)%] and control group [(38.23±18.07)%] (P<0.01). In addition, the expression of CD62p on normal platelets was higher in PNH patients than control (P<0.05). ④The deposition of C5b-9 positively correlated with the expression of CD62p on the platelets (r=0.559, P=0.002).

CONCLUSIONDeficiency of CD59 antigen on platelets in PNH patients may lead to the deposition of C5b-9 on its membrane and its dysfunction, which may contribute to thrombosis events in PNH.
