ABSTRACT

Background/Aims@#Chronic hepatitis B (CHB) and fatty liver (FL) often co-exist, but natural history data of this dual condition (CHB-FL) are sparse. Via a systematic review, conventional meta-analysis (MA) and individual patient-level data MA (IPDMA), we compared liver-related outcomes and mortality between CHB-FL and CHB-no FL patients. @*Methods@#We searched 4 databases from inception to December 2021 and pooled study-level estimates using a random- effects model for conventional MA. For IPDMA, we evaluated outcomes after balancing the two study groups with inverse probability treatment weighting (IPTW) on age, sex, cirrhosis, diabetes, ALT, HBeAg, HBV DNA, and antiviral treatment. @*Results@#We screened 2,157 articles and included 19 eligible studies (17,955 patients: 11,908 CHB-no FL; 6,047 CHB-FL) in conventional MA, which found severe heterogeneity (I2=88–95%) and no significant differences in HCC, cirrhosis, mortality, or HBsAg seroclearance incidence (P=0.27–0.93). IPDMA included 13,262 patients: 8,625 CHB-no FL and 4,637 CHB-FL patients who differed in several characteristics. The IPTW cohort included 6,955 CHB-no FL and 3,346 CHB-FL well-matched patients. CHB-FL patients (vs. CHB-no FL) had significantly lower HCC, cirrhosis, mortality and higher HBsAg seroclearance incidence (all p≤0.002), with consistent results in subgroups. CHB-FL diagnosed by liver biopsy had a higher 10-year cumulative HCC incidence than CHB-FL diagnosed with non-invasive methods (63.6% vs. 4.3%, p<0.0001). @*Conclusions@#IPDMA data with well-matched CHB patient groups showed that FL (vs. no FL) was associated with significantly lower HCC, cirrhosis, and mortality risk and higher HBsAg seroclearance probability.

ABSTRACT

Objective:To study the effect of health management based on the transtheoretical model and stages of change on patients with diabetes mellitus complicated by obesity.Methods:A total of 122 patients with type 2 diabetes mellitus (T2DM) complicated by obesity and admitted to Guangdong Second Provincial General Hospital between January 2019 and June 2020 were recruited to participate in the study. They were divided into two equal groups at random, the observation group and the control group —with 61 patients in each group. Both groups were subjected to individualized health management based on conventional drug treatment. The control group received routine health education and psychological support, while the observation group was subjected to the transtheoretical model and stages of change interventions for six months. The independent-samples t-test was used to compare blood glucose, body weight, and self-efficacy in the two groups after interventions, and the χ 2 test or Fisher′s precise test was used to compare behavior habit compliance rates in the two groups after interventions. Results:FBG with (6.27±0.92) mmol/L and (6.58±0.91) mmol/L, 2hPG with (8.53±1.39) mmol/L and (8.53±1.39) mmol/L, and HbA1c with (6.49±0.91)% and (6.78±0.96)% in the two groups were significantly lower at six months of interventions than those before ( P<0.05), but the differences between the two groups were not statistically significant ( P>0.05). BMI, waist circumference, and body fat rate with (30.46±2.51) kg/m 2, (91.72±10.45) cm, and (34.09±3.84)% of the observation group at six months of interventions were significantly lower than those before interventions ( P<0.05), whereas there were no significant changes in the control group before and after interventions ( P>0.05). The observation group′s BMI and body fat rate were lower than those of the control group ( P<0.05). The General Self-Efficacy Scale (GSES) scores in the two groups were (31.62±2.59) points and (28.75±2.48) points, which were significantly higher than those before interventions ( P<0.05). The observation group′s GSES score was higher than that of the control group ( P<0.05). At six months of interventions, the compliance rates of diet control (92.98% and 77.97%), reasonable exercise (87.72% and 71.19%), adherence to medication (98.25% and 91.53%), quitting smoking and alcohol (94.74% and 81.36%), blood glucose monitoring (91.23% and 94.92%), and regular review (100.00% and 98.31%) were all significantly higher in the two groups than those before interventions ( P<0.05). Additionally, the compliance rates of diet control, reasonable exercise, and quitting smoking and alcohol in the observation group were higher than those of the control group ( P<0.05). Conclusion:The use of the transtheoretical model and stages of change for the self-management intervention of diabetes mellitus patients with obesity is beneficial to improve self-efficacy, behavioral habits, and weight control effectiveness.

ABSTRACT

Objective:To explore the optimal postpartum nursing intervention method of elderly second-birth parturient based on the best evidence and evaluate its effect so as to improve the quality of clinical nursing.Methods:Based on the best evidence obtained from the previous study, the optimal nursing examination index of the elderly second parturient was established, and the evidence of best practice was obtained by using the evidence-based nursing method, and the 2017 revised version (the third edition of) Johns Hopkins evidence-based nursing practice model) was used to guide nurses to apply the evidence to clinical practice. During the period from March to May 2019, the baseline review was completed, including 82 pregnant women and 43 nurses. The evidence was incorporated into clinical practice in June 2019. From July to October 2019, the same indicators and inclusion and exclusion criteria were used to evaluate the effectiveness of evidence application in 43 nurses (including midwives) and 85 elderly second-child parturients in obstetric wards (including baby-friendly areas). The anxiety, depression, maternal satisfaction and nurses' correct implementation rate of the best evidence were compared before and after the application of evidence.Results:After the use of evidence-based intervention, the implementation rate of nurses was above 80%. The anxiety score of parturient decreased from 55.29±10.11 to 41.74±10.35, the difference was statistically significant ( t value was 8.55, P<0.001), and the depression score decreased from 57.77 ±8.32 to 47.86 ±9.33, the difference was statistically significant ( t value was 7.23, P<0.001). Maternal satisfaction increased from 92.68% (76/82) to 98.82% (84/85), the difference was statistically significant ( χ2 value was 3.92, P< 0.05). Conclusion:The result of practice shows that through evidence-based nursing intervention, we can further standardize the postpartum optimal nursing paradigm of elderly second-child parturients in China. Reduce postpartum anxiety and depression and improve maternal satisfaction. And quality review still needs to be continuously promoted and implemented in clinical practice in order to continuously improve the quality of nursing and ensure sustainability.

ABSTRACT

@#In this paper, a novel and simple RP-HPLC method for the determination of related substances of tiopronin for injection was described. The RP-HPLC analysis was performed on a C18 column, with acetonitrile-0. 1% phosphoric acid(8 ∶92), mobile phase in isocratic mode at a rate of 1. 0 mL/min. The photodiode array detector was set at 210 nm. Seven related substances were detected and the structures were characterized by mass spectrometry. The method showed great suitability, specificity and excellent linearity over the concentration range of 0. 3 to 50 μg/mL(r≥0. 999), and the limits of detection and quantitation were found to be 0. 10 and 0. 31 μg/mL, respectively. The accuracy of the method determined by the entire mean recovery ranged from 98. 7% to 103. 7%. The intra-and inter-day precision was satisfactory(RSD≤4. 4%)and robust(RSD≤6. 4%). And this method was successfully applied for the determination of related substances of tiopronin for injection, which revealed the retention of sulfhydryl compounds and glycine analogues on the RP-HPLC and the effect of the pH value of the mobile phase on the chromatographic behavior of the analytes.

ABSTRACT

Nursing simulation teaching is one of the important measures in nursing teaching reform. As an advanced medical teaching model, SimMan synthetic simulation has been recognized by medical educators both at home and abroad for its advantages of high simulation, repeatability, case diversity and process controllability. Our country has relied on the SimMan synthesis simulation person to carry on the nursing simulation teaching for many years, usually as a teaching strategy into the course of teaching. Its advantages and innovation are affirmed by nursing educators and learners, but still face challenges in the design of simulation teaching, the development of functions and the improvement of equipment utilization. It is worthy discussing deeply by nursing educators.

ABSTRACT

Objective To observe the effects of early-stage exercise on function recovery and ED1 expres-sion after spinal cord injury. Methods Twenty-two SD rats were randomly divided into a control group ( n=8) , an exercise group ( n=8) and a sham-operated group ( n=6) . The control and exercise groups received T9 spinal cord contusions. The sham-operated group received only T9 laminectomy without spinal cord injury. Two rats died within 6 hours after the operation and 3 others were abandoned because of motor function recovery just after the spi-nal cord contusion. The remaining 17 were included in the statistical analysis: a control group of 6, an exercise group of 5 and a sham-operated group of 6. BBB scoring was conducted 2 days later and then weekly until 8 weeks after the operation. The exercise group began treadmill and wheel running exercise on day 2 and continued 5 times per week until the 8th week. After paraformaldehyde perfusion, fixation and embedding, frozen spinal cord slices were Nissl stained for ED1 and GFAP immunofluorescence measurements. Results Compared with the control group, the average BBB score of the exercise group was significantly higher at each week except weeks 2 and 4. By weeks 7 and 8, the exercised rats showed 13.60 and 14.60 BBB punctuation, which means that those animals took frequent, consistent, weight-supporting plantar steps, consistent with FL-HL coordination. That motor behavior was not achieved by the control group even occasionally. In terms of the tissue morphology and immunohistochemical staining results, the empty area was not significantly reduced in the exercise group compared with the controls, but the damaged area was significantly reduced. In addition, ED1 positive cells in the lesioned area were significantly reduced in the exercised group compared with the controls. Conclusions Exercise can promote the recovery of motor function after spinal cord injury. The mechanism may involve reducing the lesioned area and inflammatory response.

ABSTRACT

Background:Because of its non-invasiveness,direct inspection,and high detection rate,capsule endoscopy(CE) has been accepted as the first-line examination for diagnosis of obscure gastrointestinal bleeding(OGIB). However,no matter the result of CE is positive or negative,it is unable to accurately predict the occurrence of rebleeding. Aims:To preliminarily investigate the related risk factors of rebleeding in OGIB patients with positive or negative CE for reducing the rebleeding rate. Methods:One hundred and sixteen OGIB patients undergone CE and with follow-up data from October 2009 to October 2013 at the First Affiliated Hospital of Soochow University were recruited,the rebleeding rate of patients with positive and negative CE,and the risk factors of rebleeding were analyzed. Results:CE diagnostic rate was 56. 9% , and the overall rebleeding rate was 37. 9% . The rebleeding rate in CE positive patients was significantly higher than that in CE negative patients(48. 5% vs. 24. 0% ,P < 0. 01). Male,age ≥50 years,hypertension,accumulated bleeding ≥500 mL within 3 months before CE were the independent risk factors of increase in rebleeding rate in CE positive patients. Age≥50 years,abnormal blood coagulation,without specific treatment were the independent risk factors of increase in rebleeding rate in CE negative patients. Conclusions:Followed-up should be performed in OGIB patients with risk factors of rebleeding for at least 24 months after CE. Repeated examination can be avoided in OGIB patients without risk factors.

ABSTRACT

OBJECTIVE@#To explore the effect of calcitonin gene-related peptide (CGRP) on murine oocyte maturation.@*METHODS@#After injection of pregnant mare serum gonadotropin (PMSG, 10 U, i.p.) for 48 h, 6-week old female Kunming mice were killed, and the cumulus oocyte complexes (COCs) were collected from ovaries and inoculated in the culture plate by 30-40/hole. The COCs were treated with 4 concentrations of CGRP (0, 10(-10), 10(-9), and 10(-8) mol/L), and the germinal vesicle breakdown (GVBD) and polar body I (PBI) were examined. Human granulosa cells were also cultured with CGRP (0, 10(-10), 10(-9), 10(-8) mol/L) and levels of intracellular cyclic adenosine monophosphate (cAMP) were measured.@*RESULTS@#Exogenous CGRP caused a decrease in GVBD and PBI in COCs, and an increase in cAMP levels in human granulosa cells in a concentration-dependent manner.@*CONCLUSION@#CGRP can inhibit the oocyte maturation, which may be related to the increased content of cAMP in granulosa cells.

ABSTRACT

Objective To analyze the relationship between CT characteristics of chronic subdural hematoma (CSDH) and its recurrence, as well as relevant pathological mechanism. Methods The study involved 178 patients with CSDH who underwent surgery, of whom 38 patients (40 lesions) experienced recurrence of CSDH. Univariate and multivariate logistic analyses were performed to assess the correlation among CT characteristics ( including side, density, width, subtype and midline shift of the hematoma) and CSDH recurrence. Results ( 1 ) The width of hematoma, midline shift, type of hematoma were found to be correlated with the recurrence of CSDH in the univariate analysis. The odds ratio (OR)and 95% confidence interval (CI) value of patients with hematoma width >30 mm, midline shift >10 mm and the separated type were 18. 400 (2.024-167. 301 ), 4. 643 ( 1. 815-11. 877 ) and 14. 385 (3. 601-57.467 ), respectively. (2) The midline shift and type of hematoma were found to be correlated with the recurrence of CSDH in the multivariate analysis, when the OR and 95% CI value of patients with hematoma midline shift > 10 mm and separated type were 5. 280 ( 1. 339-20. 823) and 19. 125 (4. 175-87.619), the OR and 95% CI value of patients with hematoma width >30 mm was 14. 838 ( 1. 353-162.698). Conclusions Type of hematoma and midline shift are found to be independently correlated with the recurrence of CSDH, and the width of hematoma is also related with its recurrence.

ABSTRACT

Objective To explore the effect of miR-21 on 24 h urine albumin excretion (UAE), glomeruli morphology, and its molecular mechanism in db/db mouse with early stage of diabetic nephropathy. Methods Twenty-four 5-week-old male mice were randomized into 4 groups: control group (untreated db/m mice, n=6),miR-21-treated db/db group (n=6), control empty plasmid treated db/db group (n =6), and untreated db/db group (n = 6). Mice were injected intraperitoneally using a hydrodynamics-based procedure with plasmids (30 mg · kg-1 · d-1 of miR-21 or 30 mg· kg-1 · d-1 of control plasmid) until albuminuria was detected in the untreated db/db mice. The glomeruli were observed under the light microscope, and measured by the software in the computer. The expression of miR-21 was tested by real-time RT-PCR, the expression of PTEN, p-Akt (Ser 473),and phosphatidylinositol-3-kinase (PI3K) p85α protein levels were examined by western blot and immunohistochemistry. Results Male db/db mice of 9-week-old with hyperglycemia and significant elevation of urinary albumin excretion showed features similar to the early stage of diabetic nephropathy. Real-time RT-PCR showed that miR-21 was increased in the miR-21-treated group. By measurement of glomeruli acreage, the glomeruli were smaller in miR-21-treated group than in the control empty plasmid treated and untreated groups (all P<0.01). By Western blot and immunohistochemistry, PTEN were reduced in the miR-21-treated group, whereas PI3K p85α and phospho-Akt (Ser 473 ) were increased in miR-21-treated group (all P < 0.01). Conclusions miR-21 ameliorates glomerular hypertrophy in db/db mice with diabetic nephropathy, and it may be a novel protecting factor of diabetic nephropathy.

ABSTRACT

<p><b>BACKGROUND AND OBJECTIVE</b>Transient receptor potential canonical (TRPC) proteins, a group of Ca2' permeable nonselective cation channels, are thought to constitute store-operated calcium channels (SOCC) and mediate store-operated calcium entry (SOCE) in various cell types. Members of TRPC have been found to be involved in abnormal proliferation, differentiation, and growth of cancer cells. The aim of this study is to detect the mRNA and protein expression of TRPC in non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>Real-time quantitative PCRwas performed to screen the expression of TRPC mRNA in NSCLC tissue. Protein expression of TRPC was detected by Western blot.</p><p><b>RESULTS</b>Among the seven family members of TRPC so far identified (TRPC1-7), we detected the expression ofTRPC1, TRPC3, TRPC4, TRPC6 mRNA in 24 cases of NSCLC tissue; TRPC2, TRPC5 and TRPC7 mRNA were not detectable. The relative abundance of the expressed TRPC was TRPC1 approximately equal TRPC6 > TRPC3 > TRPC4. Western blot confirmed the protein expression of TRPC1, TRPC3, TRPC4 and TRPC6 in NSCLC tissue.</p><p><b>CONCLUSION</b>Out of the seven members of TRPC, we found TRPC1, TRPC3, TRPC4, TRPC6 mRNA and protein were selectively expressed in human NSCLC tissue. This study could provide a basis for future exploration of the individual role of these TRPC proteins in mediating SOCE and in the progression of lung cancer.</p>

ABSTRACT

OBJECTIVE: To summarize advances in clinical application of ureter stent and its biocompatibility. METHODS: A computer-based online search of CNKI (1989/2009) and Medline (1989/2009) was performed with the key words of "ureter, biocompatibility, stent, treatment, complications" in Chinese and English respectively. A total of 51 articles were collected. and 21 were included. The treatment advances and its biocompatibility of ureter stent were summarized, and clinical application advances, biocompatibility and complication prevention of ureter stent were explored. RESULTS: Ureter stent includes polymerizer, metal and degradable material stents. As the common implants in treatment of upper urinary tract diseases, ureter stent functions as stent and internal drainage, and relieve ureteral obstruction, prevent leakage of urine postoperatively and ureterostenosis. Complications following ureter stent implantation include stent shifting, urine reflux, irdtative symptoms of bladder, fouling and stone formation as well as infection. However, these complications can be relieved through positive treatment. CONCLUSION: Ureter stent is an effective approach to treat urologic disease, but the biocompatibility required improvement. Rigorous operation during stent implantation and positive treatment of complication can effectively prevent complications.
