Objective:To explore the effects of prenatal targeted psychological interventions combined with yoga on maternal anxiety, depression and maternal and infant outcomes.Methods:A total of 100 pregnant and puerperal women who were enrolled in Jining maternal and child health family planning service center from January 2021 to December 2022 and received regular prenatal care as required were selected as study subjects. According to the random number method, the subjects were divided into experimental and control groups, with 50 cases in each group. The experimental group was given targeted psychological interventions combined with yoga training, while the control group was given only traditional nursing. Then the differences of the self-rating anxiety scale (SAS) score, the self-rating depression scale (SDS) score, the general self-efficacy scale (GSES) score, the maternal and infant outcomes, body mass index (BMI) and the satisfaction of postpartum women were compared between the two groups. SPSS 26.0 software was used for analysis. The χ2 test, independent sample t-test, paired sample t-test were used for statistical analysis. Results:After the intervention, the scores of SAS and SDS of the experimental group were lower than those of the control group (SAS: (36.86±6.89), (44.12±11.04); SDS: (38.92±7.62), (48.20±10.44)), and the difference was statistically significant ( tSAS=-3.946, tSDS=-5.077, both P<0.05). Following the intervention, the GSES score of the experimental group was higher than that of the control group ((2.92±0.49), (2.57±0.58)), and the difference was statistically significant ( t=3.246, P<0.05). After the intervention, the cesarean section rate and the birth rate of macrosomia in the experimental group were lower than those in the control group(10.0%, 26.0%; 4.0%, 16.0%), and the rate of breastfeeding was higher than that of the control group(86.0%, 68.0%), and the differences were statistically significant ( χcesarean2=4.336, χmacrosomia2=4.000, χbreastfeeding2=4.574, all P<0.05). However, no significant difference was found in the postpartum hemorrhage rate between the experimental group and the control group ( P>0.05). Following the intervention, BMI of the experimental group was lower than that of the control group((26.11±2.18)kg/m 2, (28.02±1.97)kg/m 2, ( t=-4.609, P<0.05). In addition, postpartum women in the experimental group were significantly more satisfied than those in the control group (96.0%, 82.0%; χ2=5.005, P<0.05). Conclusion:The combination of prenatal targeted psychological interventions and yoga can reduce maternal anxiety and depression during pregnancy, get body back in shape after having a baby, and improve self-efficacy, satisfaction and the maternal and infant outcomes.

Objective:To explore the effects of strengthening night professional nursing of patients with open fractures of the lower extremities.Methods:From January 2019 to June 2020, convenience sampling was used to select 397 patients with open fractures of the lower extremities from the First Orthopedic Trauma, the Third Hospital of Hebei Medical University. Patients were randomly assigned to a control group and an observation group, respectively, to receive general nursing (control group) and strengthening night professional nursing (observation group). The control group was equipped with a regular number of nurses. In the observation group, an additional night nurse was assigned for patients undergoing surgery for open fractures of the lower extremities. The nighttime period was from 18∶00 to 8∶00 the next day. The night nurse arranged compensatory time off for the rest of the time or performance rewards. The hospital stay, hospitalization expenses, incidence of complications during hospitalization and half a year after surgery of the two groups were compared.Results:In the control group, there were 196 patients with open fractures of the lower extremities, and 46 patients underwent night surgery. In the observation group, there were 201 patients with open fractures of the lower extremities, and 40 patients underwent night surgery. There were no statistically significant differences between two groups in terms of surgical time, incidence of complications during hospitalization and half a year after surgery ( P>0.05). The hospital stay in the observation group was shorter than that in the control group, and the hospitalization expense was lower than that in the control group, with statistically significant differences ( P<0.05) . Conclusions:Strengthening night professional nursing can help shorten the hospital stay of patients undergoing surgery for open fractures of the lower extremities and reduce medical expenses.

Metabolic-associated fatty liver disease (MAFLD), which is previously known as non-alcoholic fatty liver disease (NAFLD), represents a major health concern worldwide with limited therapy. Here, we provide evidence that ferroptosis, a novel form of regulated cell death characterized by iron-driven lipid peroxidation, was comprehensively activated in liver tissues from MAFLD patients. The canonical-GPX4 (cGPX4), which is the most important negative controller of ferroptosis, is downregulated at protein but not mRNA level. Interestingly, a non-canonical GPX4 transcript-variant is induced (inducible-GPX4, iGPX4) in MAFLD condition. The high fat-fructose/sucrose diet (HFFD) and methionine/choline-deficient diet (MCD)-induced MAFLD pathologies, including hepatocellular ballooning, steatohepatitis and fibrosis, were attenuated and aggravated, respectively, in cGPX4-and iGPX4-knockin mice. cGPX4 and iGPX4 isoforms also displayed opposing effects on oxidative stress and ferroptosis in hepatocytes. Knockdown of iGPX4 by siRNA alleviated lipid stress, ferroptosis and cell injury. Mechanistically, the triggered iGPX4 interacts with cGPX4 to facilitate the transformation of cGPX4 from enzymatic-active monomer to enzymatic-inactive oligomers upon lipid stress, and thus promotes ferroptosis. Co-immunoprecipitation and nano LC-MS/MS analyses confirmed the interaction between iGPX4 and cGPX4. Our results reveal a detrimental role of non-canonical GPX4 isoform in ferroptosis, and indicate selectively targeting iGPX4 may be a promising therapeutic strategy for MAFLD.

Objective: To explore mechanism of how nurse managers' transformational leadership affects patient satisfaction, and to examine the mediating role of nurses' psychological empowerment. Methods: A total of 140 nurses and 310 patients in Sun Yat-sen University Cancer Center were surveyed. The Leadership Practice Inventory-other, the Psychological Empowerment Scale and two items from the Hospital Consumer Assessment of Healthcare Providers and Systems Survey (Chinese version) were used to measure nurse-perceived nurse managers' transformational leadership behaviors, nurses' psychological empowerment and patient satisfaction. The descriptive statistics and correlation analysis were performed using the SPSS 20.0. software package, and the structure equation modeling was performed using the MPlus 7.0. Results: Higher frequencies of nurse managers adopting transformational leadership were associated with higher level of nurses' psychological empowerment (β=0.665, P < 0.05); higher level of nurses' psychological empowerment was associated with higher overall patient satisfaction (β=0.243, P < 0.05); nurses' psychological empowerment mediated the relationship between nurse managers' transformational leadership and patients' overall satisfaction (β=0.162, P=0.014); the effects of nurse managers' transformational leadership and nurses' psychological empowerment on patients' recommendation of hospital were not statistically significant (P>0.05). Conclusions Nurse managers are encouraged to adopt transformational leadership, i.e., improving clinical and leadership skills, trying to be nurses' role model, solving problems at work, empowering and motivating nurses, thus to increase nurses' senses of empowerment, and to improve patient satisfaction eventually.

Objective: To investigate the application value of magnetic resonance imaging (MRI) in the classification diagnosis of rectal mucinous adenocarcinoma. Methods: The retrospective and descriptive study was conducted. The clinical data of 74 patients with rectal mucinous adenocarcinoma who were admitted to Chongqing Traditional Chinese Medicine Hospital from July 2009 and February 2019 were collected. There were 40 males and 34 females, aged (46±8)years, with a range from 32 to 82 years. Among the 74 patients, 41 were simple mucinous adenocarcinoma, 26 were partial mucinous adenocarcinoma, and 7 were focal or small foci mucinous adenocarcinoma. All patients underwent MRI plain scan and dynamic enhanced scan. Observation indicators: (1) morphology of rectal mucinous adenocarcinoma; (2) the lesion margin of rectal mucinous adenocarcinoma; (3) the value of apparent diffusion coefficient (ADC) of rectal mucinous adenocarcinoma; (4) internal enhancement features of rectal mucinous adenocarcinoma; (5) timesignal intensity curve of rectal mucinous adenocarcinoma. Measurement data with normal distribution were represented as Mean±SD, and count data were described as absolute numbers. Results: (1) Morphology of rectal mucinous adenocarcinoma: 74 patients had different morphological changes. Among the 41 cases of simple mucinous adenocarcinoma, 22 were oval, 8 were round, and 11 were irregular. Among the 26 patients with partial mucinous adenocarcinoma, 15 were oval, 8 were round and 3 were irregular. Among the 7 patients with focal or small foci mucinous adenocarcinoma, 2 were oval, 1 was round and 4 were irregular. (2) The lesion margin of rectal mucinous adenocarcinoma: the lesion margin of 74 patients was mainly unclear and irregular. Among the 41 cases of simple mucinous adenocarcinoma, 32 had unclear and irregular margin, 7 had clear margin, and 2 had unclear margin combined with fissure. Among the 26 cases of partial mucinous adenocarcinoma, 20 had unclear margin combined with fissure, 5 had unclear margin and irregular margin, and 1 had clear margin. Among the 7 patients with focal or small foci mucinous adenocarcinoma, 5 had unclear or irregular margin, 1 had unclear or irregular margin, and 1 had clear margin. (3) The value of ADC of rectal mucinous adenocarcinoma: diffusion weighted imaging of 74 patients showed diffused limited changes. The average ADC value was (1.24±0.23)×10^-3 mm²/s of 41 patients with simple mucinous adenocarcinoma, (0.91±0.42)×10^-3 mm²/s of 26 patients with partial mucinous adenocarcinoma, and (1.07±0.24)×10^-3 mm²/s of 7 patients with focal or small mucinous adenocarcinoma. (4) Internal enhancement features of rectal mucinous adenocarcinoma: 74 patients showed delayed heterogeneous enhancement and marginal enhancement. Among 41 cases of simple mucinous adenocarcinoma, 24 showed delayed heterogeneous enhancement, 17 showed marginal enhancement, and none showed homogeneous enhancement. Among 26 patients with partial mucinous adenocarcinoma, 20 showed marginal enhancement, 6 showed homogeneous enhancement, and none showed heterogeneous enhancement. All the 7 cases of focal or small foci mucinous adenocarcinoma showed heterogeneous enhancement. (5) Timesignal intensity curve of rectal mucinous adenocarcinoma: 74 patients showed mainly outflow type in the timesignal intensity curve. Among the 41 cases of simple mucinous adenocarcinoma, 22 presented progressive curve, 12 presented platform type, and 7 presented outflow type.

Among the 7 patients with focal and small forci mucinous adenocarcinoma, 4 presented outflow type, 2 presented platform type, and 1 presented progressive type. Conclusions MRI findings show different results for different types of rectal mucinous adenocarcinoma. A correct understanding of the MRI features of different types of rectal mucinous adenocarcinoma is helpful for the classification diagnosis of rectal mucinous adenocarcinoma.

Investigating the influence of acupuncture on cellular signal transduction is an efficient pathway to reveal the action mechanism of acupuncture on spinal cord injury (SCI). In this study, the experiment research literature regarding acupuncture for SCI during past 10 years was reviewed and analyzed. As a result, it was found that acupuncture could regulate the expression of the first intercellular messenger as well as the second signal molecules including cyclic adenosine monophosphate, cyclic guanosine monophosphate, Ca2+, nitric oxide to intervene the apoptotic signaling pathway, Rho/Rock signaling pathway, Wnt signaling pathway, MAPK signaling pathway, Notch signaling pathway, etc., which could improve regeneration and repair of SCI. In conclusion, in future researches more attention should be paid to the cellular signal transduction networks and different effects among various acupoint combinations and acupuncture modalities on cellular signal transduction, which have an essential role for revelation of clinical application rules and optimization of clinical treatment protocol.

Objective To observe the effect of electroacupuncture on Caspase-9, cytochrome C (Cyt-C) and apoptotic protease activating factor 1 (Apaf-1) protein in rats with neurogenic bladder after complete spinal cord injury. Methods A total of 60 female Sprague-Dawley rats were involved, in which 36 rats were randomly selected to establish the neurogenic bladder model with T10 spinal cord transected. 24 successful models selected were randomly divided into model group (n=12) and electroacupuncture group (n=12). The other 24 rats were also randomly divided into sham group (n=12) and blank group (n=12). The electroacupuncture group was electroacupunctured on Ciliao (BL32), Zhongji (RN3), Sanyinjiao (SP6) and Dazhui (GV14) for seven days. All of them were assessed with urodynamic test, TUNEL method was used to determine the apoptosis rate of the spinal cord, and Western blotting was used to detect the expression of Caspase-9, Cyt-C and Apaf-1 protein. Results Compared with the blank group and the sham group, the maximum bladder capacity and compliance decreased (P<0.01), the urinary bladder pressure and leakage point pressure increased (P<0.05); the apoptosis rate of the spinal cord increased (P<0.001); the expression of Caspase-9, Cyt-C and Apaf-1 protein increased (P<0.05) in the model group and the electroacupuncture group. Compared with the model group, the maximum bladder capacity and compliance increased (P<0.01), the urinary bladder pressure and leakage point pressure decreased (P<0.05); the apoptosis rate of the spinal cord decreased (P<0.05); the expression of Caspase-9, Cyt-C and Apaf-1 protein decreased (P<0.05) in the electroacupuncture group. Conclusion Electroacupuncture on Ciliao, Zhongji, Sanyinjiao and Dazhui could improve the bladder function after spinal cord injury in rats. The mechanisms may be related with the down-regulation of Caspase-9, Cyt-C and Apaf-1 protein to reduce apoptosis.

Objective To establish the rat model for neurogenic bladder after complete suprasacral spinal cord injury, and analyze the urodynamics. Methods Forty adult Sprague-Dawley rats were randomly divided into control group (n=10) and experimental group (n=30). The spinal cord injury model on T10 was made with modified spinal cord transaction. The Crede's method was used to urinate assistantly af-ter modeling. The amounts of urine and successful rat model everyday were recorded. The urodynamics was measured in both groups, and the morphology was observed with HE staining. Results Four rats died in the experimental group. The amount of urine was the least and sta-ble on the 18th day, and 24 rats were successfully modeled on the 21st day. Compared with the control group, maximum bladder capacity de-creased (t=3.150, P=0.021), bladder base pressure, maximum bladder pressure and leak point pressure increased (t>3.125, P<0.01), and blad-der compliancy decreased (t=5.330, P=0.002) in the experimental group. Conclusion The complete suprasacral after spinal cord injury of neurogenic bladder in a rat model of manufacturing method is of high reliability, good repeatability, and low coefficient of variable character-istics for spastistic neurogenic bladder basic experimental studies.
