ABSTRACT

Objective:To understand the potential categories of self-efficacy in stress injury management of nurses in operating room and analyze the characteristics of different categories of nurses.Methods:A cross-sectional survey was conducted from June to August 2022. A total of 469 operating room nurses from 12 Grade A hospitals in Guangxi, Sichuan, Guizhou, Yunnan, Shanxi, Xinjiang and Chongqing were selected by convenient sampling method as subjects. General data questionnaire, proactive personality Inventory, Caring behavior Inventory, transformational leadership inventory, nursing clinical Decision scale and nurses stress injury management self-efficacy scale were used to investigate. Potential profile was used to analyze nurses' self-efficacy in stress injury management, and multiple Logistic regression was used to analyze different potential factors.Results:The self-efficacy of nurses in the management of stress injury in operating room could be divided into three potential profiles: poor self-efficacy group (23.9%, 112/469), medium self-efficacy group (33.0%, 155/469) and good self-efficacy group (43.1%, 202/469). Proactive personality, caring behavior, transformational leadership, nursing clinical decision-making and educational background were the factors influencing self-efficacy of operating room nurses in stress injury management (all P<0.05). Conclusions:There are three potential profiles of self-efficacy in the management of stress injury in operating room nurses. Nursing managers can give targeted intervention strategies according to different characteristics of nurses to improve their self-efficacy.

ABSTRACT

The present study developed an oral hepatocyte growth factor (HGF) gene therapy strategy for gastric ulcers treatment. An attenuated Salmonella typhimurium that stably expressed high HGF (named as TPH) was constructed, and the antiulcerogenic effect of TPH was evaluated in a rat model of gastric ulcers that created by acetic acid subserosal injection. From day 5 after injection, TPH (1 × 10⁹ cfu), vehicle (TP, 1 × 10⁹ cfu), or sodium bicarbonate (model control) was administered orally every alternate day for three times. Then ulcer size was measured at day 21 after ulcer induction. The ulcer area in TPH-treated group was 10.56 ± 3.30 mm², which was smaller when compared with those in the TP-treated and model control groups (43.47 ± 4.18 and 56.25 ± 6.38 mm², respectively). A higher level of reepithelialization was found in TPH-treated group and the crawling length of gastric epithelial cells was significantly longer than in the other two groups (P < 0.05). The microvessel density in the ulcer granulation tissues of the TPH-treated rats was 39.9 vessels/mm², which was greater than in the TP-treated and model control rats, with a significant statistical difference. These results suggest that TPH treatment significantly accelerates the healing of gastric ulcers via stimulating proliferation of gastric epithelial cells and enhancing angiogenesis on gastric ulcer site.

ABSTRACT

Objective To explore the telomere length (TL) in buccal cells and its possible implications for long-lived families of Zhuang nationality in Bama area of Guangxi.Methods Relative TL in buccal cells from Bama long-lived families (BLF,n=1250) was determined by real time PCR and compared between Bama non-long-lived families (BNLF,n=556) and Pingguo longlived families (PLF,n=630).All participants were Zhuang ethnic.Results The TL in buccal cells was negatively correlated with age (R=-0.215,P=0.000) and was independent of sex in all subjects (n=2436).There were no significant differences in TL between males and females in different of ages in BLF (all P>0.05).Similar tendency was observed in most but not all age groups in the two other families.The TL was significantly longer in BLF aged over 65 years (the first offspring of the longlived individual) than in BNLF aged over 65 years (1.969 vs.1.622,P=0.004) and the TL of BLF aged over 90 years was comparable to that of BNLF aged over 65 years (1.662 vs.1.622,P=0.955),which indicating that the offspring of long-lived individuals inherited longer TL from their parental generation.Conclusions Telomere length is shorten with aging in long-lived families in Bama area.The TL of BLF has a tendency of inheritance,which may be one of the mechanisms of longevity in Bama area.

ABSTRACT

Cerebral ischemia is one of the most common diseases treated by acupuncture therapeutics. Recent studies indicated that acupuncture treatment by needling the conception and governor vessels had positive effects in promoting neural regeneration in patients after cerebral ischemia injury. Acupuncture intervention could continuously promote the proliferation and differentiation of the neural stem cells in the brain, obviously up-regulate expression of growth factors, accelerate angiogenesis and inhibit apoptosis. Hence, it is necessary to present an exhaustive review on the mechanisms. The present review gives a detailed description of pathological changes of cerebral ischemia and acupuncture intervention applied to the conception and governor vessels, and proposes research prospects in the future.
