[Summary] Thirty-two SD rats were randomly divided into noraml control group(NC, n = 10) and high fat diet group(HF, n=22). 10 weeks later, the HF group rats were injected STZ(30 mg/ kg) to set up the model of diabetes complicating with nonalcoholic fatty liver disease (NAFLD). Then, HF group were randomly divided into model control group(MC, n = 8) and Saxagliptin intervene group( M + S, n = 8). The M + S group were made an intervention with Saxagliptin(10 mg·kg-1 ·d-1 ) for 8 weeks. At the end of 18 weeks, the fasting blood glucose, serum insulin, liver function, liver weight, tumor necrosis factor alpha, and interleukin 6 were measured. HOMA-IR was calculated. Western bolt was used to determine the expression of NF-κB in hepatic tissue. The level of the indexes above increased in the MC group than in the NC group. But the indexes above mentioned in M + S group were ameliorated. The expression of NF-κB was significantly up regulated in MC group as compared with the NC group, and significantly reduced in the M+S group than in the MC group. The results of correlation analysis revealed that TNF-αand IL-6 were positive correlated with HOMR-IR, respectively. Saxagliptin can effectively reduce the blood glucose level and alleviate insulin resistance, then further relieve the inflammation of liver injury, and finally to alleviate the condition of T2DM with NAFLD. It may play a protective role in the damaged hepatic cells.

Objective To investigate the effect of comprehensive nursing intervention and evaluate its role in the entire clinical course of in the treatment of children with severe burns. Methods A total of 60 children with 1-5 years old with clinical diagnosis of severe burns were randomly divided into experimental group and control group by random digits table method, 30 cases in each group. The control group received routine burn care. The experimental group received comprehensive nursing interventions on the basis of routine burn care and the intervention time covered the entire course of treatment. During hospitalization, the recovery and family social system were evaluated by anxiety scales and social support scales combined with the cure rate and hospitalization of children. Results Before intervention, the score of Anxiety Rating Scale was high in both groups of families, while Social Support Scale was lower, the difference was not statistically significant between the two groups (P>0.05). After intervention, the score of Anxiety Rating Scale and was Social Support Scale were (52.31±7.81), (31.52± 5.48)points in the experimental group, and (62.51 ± 6.52), (23.62 ± 5.62) points in the control group, and there were significant differences (t=5.491 3, 5.512 5, P<0.01). The length of stay was (18.34±3.58) d in the experimental group, and (21.82 ± 4.23) d in the control group, and there was significant difference(t=3.439 6, P<0.05). The cure rate was 93.33%(28/30) in the experimental group, and 56.67%(17/30) in the control group, and there was significant difference(χ2=10.755 6, P<0.05). Conclusions The comprehensive nursing intervention can provide comprehensive refinement of the overall care in children and their families, promote physical and psychological rehabilitation of children with severe burns, and repair their family and social support systems. The comprehensive nursing intervention has far-reaching implications for the rehabilitation of children with severe burns.

Objective:To explore the role and mechanism of tubastatin A (TubA) in alleviating brain injury after cardiac arrest and cardiopulmonary resuscitation (CA-CPR) by inhibiting endoplasmic reticulum stress-mediated cell apoptosis in swine.Methods:Twenty-three conventional male white swine, weighing 33-40 kg, aged 4 to 6 months, were divided into 3 groups by random number table method: sham group ( n=6), CA-CPR group ( n=9), and TubA group ( n=8). The CA-CPR swine model was established by 9 min of electrically induced CA through pacing catheter in the right ventricle and then 6 min of CPR in the CA-CPR group. The CA-CPR swine model was established by the same method, and then a dose of 4.5 mg/kg of TubA at 5 min after resuscitation was intravenously infused in the TubA group. The serum concentrations of neuron specific enolase (NSE) and S100β protein (S100β) were measured using ELISA before modeling and at 1, 2, 4 and 24 h after resuscitation. Neurological deficit score (NDS) was evaluated at 24 h after resuscitation. Thereafter, the animals were euthanized, and brain cortex tissues were harvested, and the expression levels of caspase-12 and caspase-3 were measured using immunohistochemistry. Cell apoptosis index was detected by TUNEL assay. The variables among the three groups were compared with one-way analysis of variance and the Bonferroni hoc test using SPSS software. Results:Twenty-four h after resuscitation, the serum concentrations of NSE and S100β were significantly increased, and NDS was markedly elevated in the CA-CPR and TubA groups compared with the sham group (all P<0.05). Compared with the CA-CPR group, serum concentration of NSE starting 2 h after resuscitation and serum concentration of S100β starting 1 h after resuscitation were significantly decreased in the TubA group [NSE (ng/mL): (23.1±2.0) vs. (20.2±2.0) at 2 h, (28.4±2.3) vs. (23.7±1.9) at 4 h, (32.1±2.7) vs. (26.6±2.0) at 24 h; S100β (pg/mL): (2239±193) vs. (1923±101) at 1 h, (2817±157) vs. (2360±141) at 2 h, (3384±250) vs. (2691±210) at 4 h, (3965±303) vs. (3119±260) at 24 h, all P<0.05], and NDS was markedly reduced (240±30 vs. 63±44, P<0.05). At 24 h after resuscitation, brain cortex tissue detection showed that the expression levels of caspase-12 and caspase-3 were significantly increased, and cell apoptosis index was markedly elevated in the CA-CPR and TubA groups compared with the sham group (all P<0.05). However, the expression levels of caspase-12 and caspase-3 were significantly decreased [caspase-12:(7.1±0.7) vs. (4.2±0.4); caspase-3: (13.3±1.6) vs. (7.7±0.8), all P<0.05], and cell apoptosis index was markedly reduced in the TubA group compared to the CA-CPR group [(31.1±8.6) vs. (17.3±2.2), P<0.05]. Conclusions:TubA alleviates brain injury and neurological dysfunction after CA-CPR in swine, which may be related to the inhibition of cell apoptosis mediated by endoplasmic reticulum stress.

Objective:To evaluate the efficacy and safety of Tuina(Chinese therapeutic massage)in the treatment of functional dyspepsia(FD)in children and adults. Methods:Related articles in PubMed,Excerpta Medica Database(EMBASE),Cochrane Library,Web of Science,China Biology Medicine Disc(CBM),Wanfang Academic Journal Full-text Database(Wanfang),China National Knowledge Infrastructure(CNKI),and Chongqing VIP Database(CQVIP)were collected.The retrieval time was from each database's start to March 2022.Two researchers independently screened the literature,extracted the data,and evaluated the risk of bias in the included studies.A meta-analysis was then performed using the RevMan 5.4 software. Results:A total of 19 clinical trials were included,9 of which encompassed studies on adults while 10 were on children with FD,comprising a total of 1961 patients.The findings of the meta-analysis showed that the effective rate of FD in children and adults treated with Tuina was significantly higher than that in the control group[risk ratio(RR)=1.15,95%confidence interval(CI)(1.09,1.21),P<0.001],[RR=1.13,95%CI(1.06,1.21),P<0.001].In addition,the effective rate of FD in children and adults treated with Tuina combined with other treatments was significantly higher than that in the control group[RR=1.14,95%CI(1.07,1.21),P<0.001],[RR=1.12,95%CI(1.02,1.24),P=0.02].In terms of single symptoms,Tuina improved epigastric burning sensation score in adults[standardized mean difference(SMD)=-0.41;95%CI(-0.79,-0.02);Z=2.08;P=0.04]compared with that of the Western medicine group.Compared with children treated with oral Chinese medications(CM)or Chinese patent medicine(CPM),children with FD demonstrated lower scores of epigastric pain[SMD=-0.38,95%CI(-0.56,-0.19);Z=3.96;P<0.001],postprandial fullness[SMD=-0.30,95%CI(-0.50,-0.10);Z=2.88;P=0.004],and early satiety[SMD=-0.26,95%CI(-0.47,-0.06);Z=2.54;P=0.01]after receiving Tuina combined with CM or CPM treatment.No adverse events were reported in the Tuina treatment group,and the follow-up indicated that the symptom scores in the Tuina group improved. Conclusion:Compared with the control group,both Tuina and Tuina combined with other treatments are shown to have better effective rates,lower incidence of adverse events,and better follow-up outcomes.The study results suggest that Tuina may be a clinically viable complementary therapy.However,due to limitations in the number and quality of the included studies,the above conclusions should be verified by further high-quality studies.

OBJECTIVE: To explore the value of non-invasive prenatal testing (NIPT) for the detection of fetal chromosome copy number variations (CNVs). METHODS: Clinical data of 18 661 pregnant women who underwent NIPT were collected. For fetuses suspected for carrying CNVs, amniotic fluid samples were collected for chromosomal karyotyping and/or chromosomal microarray analysis (CMA). RESULTS: Among all samples, NIPT suggested that 58 fetuses carried trisomy 21, 18 carried trisomy 18, 19 carried trisomy 13, 1 carried trisomies 18 and 21. Eighty eight women accepted invasive prenatal diagnosis. The results of CMA in 59 cases were consistent with those of NIPT, which yielded a consistency rate of 67.05%. In addition, 37 cases of fetal CNVs were detected by NIPT, of which 19 (15 microdeletions and 4 microduplications) have accepted invasive prenatal diagnosis. In 14 cases, the results were consistency with those of NIPT, with a consistent rate of 73.68%. CONCLUSION NIPT features high sensitivity and accuracy. Invasive prenatal diagnosis should be considered for CNVs detected by NIPT, and by tracing its parental origin, it can provide guidance for clinical practice.

Objective To utilize evidence-based nursing to extubate stomach tube early for one patients with postoperative hepatectomy, and to evaluate clinical effects and the impact on postoperative rehabilitation.Methods According to patient′ s condition and clinical issues of PICO principle, we retrieve Ovid-EBM Reviews, Medline, Trip Database, CNKI, Wanfang Database, VIP Database and so on from 1995 to 2014 to acquire the clinical guideline, system evaluation, random control trail, evidence abstract and literature review and other evidences, and assess the quality of acquired evidences. Results There were 2 system evaluation, 3 random control trail, 1 non-random control trail. The extubation of stomach tube early after hepatectomy could minimize the discomfort incidences of pharynx, promote the recovery of gastrointestinal function, and could not increase the complication incidences of patients′ nausea, vomiting, ventosity, pulmonary infections and so on. Combined with patient′s condition and intention, the stomach tube could be extubate 10 hrs after hepatectomy and patients could discharged 7 d after operation. Conclusions The extubation of stomach tube early after hepatectomy is a safe and feasible method which is beneficial for patients′ recovery.

Objective To explore the effects of vascular risk factors on cognitive function among the elderly in community. Methods A cross-sectional study was conducted in 1 269 elderly people ( aged 65 and over) who were randomly selected from three communities. Through face-to-face interview, cognitive function was assessed by mini-mental state examination(MMSE),and blood samples were collected for labo-ratory examination. Logistic regression analysis was used to analyze the vascular risk factors affecting cogni-tive function. Results Age (( 73. 1 ± 6. 6), ( 71. 3 ± 4. 9),t=4. 603,P<0. 05),education level ( χ2=12. 727,P<0. 05),hypertension (χ2=9. 106,P<0. 05) and LDL-C (χ2=5. 157,P<0. 05) were significantly different in the elderly with or without mild cognitive impairment(MCI). After controlling age,gender and ed-ucation,the logistic regression analysis showed that hypertension(β=0. 378,P=0. 006,OR(95%CI)=1. 44 (1. 10-1. 91)),systolic blood pressure ≥140 mmHg( β=0. 350,P=0. 011,OR( 95% CI)= 1. 42( 1. 08-1. 86),1 mmHg=0. 133 kPa),and high LDL-C( β=0. 355,P=0. 014,OR(95%CI)=1. 43( 1. 08-1. 89)) were the risk factors of MCI in the elderly in the community. Hypertension alone or high LDL-C (β=0. 365, P=0. 029,OR(95%CI)=1. 44(1. 04-2. 00)) alone was risk factor for mild cognitive impairment in the eld-erly in the community. The risk of mild cognitive impairment in the elderly with hypertension and high LDL- C was 2. 00 times higher than that in the healthy elderly ( β=0. 696,P<0. 05,OR( 95%CI)= 2. 00( 1. 36-2. 97)). Conclusion Mild cognitive impairment in the elderly is closely related to hypertension and elevat-ed LDL-C levels. Multiple vascular risk factors can further increase the risk of cognitive impairment.
