Objective:To explore the effect of timely induction intervention on postpartum urination in primipara during vaginal delivery, so as to provide the evidence for preventing the occurrence of postpartum urinary retention and relieving the pain of primipara.Methods:This study adopted a randomized controlled trial design, and selected 400 cases of primipara who were hospitalized for vaginal delivery in the Obstetric Department of Dalian Women and Children's Medical Group Sports New Town Hospital from June 2021 to September 2022 as the study objects by convenience sampling method. They were divided into the intervention group and the control group with 200 cases each by random number table method, and the control group received routine postpartum care. Instruct active urination within 6 hours after delivery. The intervention received timely induction urination intervention. The general condition and bladder urine volume of the women in the intervention group were evaluated at 2, 4, 6 h after delivery, respectively, and personalized guidance was implemented, including the frequency of massage of the bottom of the uterus, the control of water intake, the selection of methods and timing of inducing urination, etc., and routine postpartum care was given when the women completed their first urination and had no complaints of discomfort. The first urination time, first urination volume, first bladder irritation during the first urination and the incidence of postpartum urinary retention in different periods were compared between the two groups.Results:The patients in the control group were (29.60 ± 3.20) years old, while the patients in the intervention group were (28.81 ± 3.42) years old. The first urination time in the intervention group was (6.89 ± 2.18) h, which was shorter than that in the control group (9.11 ± 3.86) h, and the difference was statistically significant ( t=-2.49, P<0.01). The first urination volume in the intervention group was (322.36 ± 120.15) ml, which was higher than that in the control group (262.93 ± 105.68) ml, and the difference was statistically significant ( t=3.39, P<0.05). The incidence of the first bladder irritation in the intervention group was 22.0%(44/200), which was lower than that in the control group 33.5%(67/200), and the difference was statistically significant ( χ2=6.60, P<0.05). The incidence of postpartum urinary retention within 24 h in the intervention group was 5.5%(11/200), which was lower than that in the control group 11.5%(23/200), and the difference was statistically significant ( χ2=4.63, P<0.05). The incidence of postpartum urinary retention within 1 week in the intervention group was 9.5%(19/200), which was lower than that in the control group 16.5%(33/200), and the difference was statistically significant ( χ2=4.33, P<0.05). There was no significant difference in the incidence of postpartum urinary retention within 24 to 72 h between the two groups ( P>0.05). Conclusions:Timely induction intervention can reduce the incidence of postpartum urinary retention, shorten the time of first urination, increase the volume of first urination and improve the comfort of first urination, which is worthy of clinical application.

Objective To investigate the level of glycosylated albumin (GA) in liver cirrhosis patients with different Child-Pugh classes and its application value in predicting liver function. Methods A total of 486 patients with liver cirrhosis who were hospitalized in Tianjin Third Central Hospital from January 1 to December 31, 2019, were enrolled, among whom 227 patients had liver cirrhosis without diabetes and 259 patients had liver cirrhosis with diabetes. The patients were divided into groups according to Child-Turcotte-Pugh (CTP) score, and fasting blood glucose, glycosylated hemoglobin, and percentage of GA (GA%) were measured. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between three groups, and the Dwass-Steel-Critchlow-Fligner test was used for further comparison between two groups. Scatter plots and fitting curves were plotted for CTP score and GA% to evaluate the association between them and calculate the cut-off value. Results For the cirrhosis patients without diabetes, there were significant differences between the patients with different Child-Pugh classes in GA% ( χ 2 =24.809, P < 0.001), fasting blood glucose ( χ 2 =11.899, P =0.003), and glycosylated hemoglobin ( χ 2 =13.607, P =0.001); further pairwise comparison showed that there was a significant difference in GA% between Child-Pugh class A/B liver cirrhosis patients without diabetes and Child-Pugh class C liver cirrhosis patients ( P < 0.05), Child-Pugh class A patients had a significantly higher level of fasting blood glucose than Child-Pugh class B patients ( P < 0.05), and Child-Pugh class A patients had a significantly higher level of glycosylated hemoglobin than Child-Pugh class B/C patients ( P < 0.05). For the patients with liver cirrhosis and diabetes, there were significant differences between the patients with different Child-Pugh classes in GA% ( χ 2 =10.734, P =0.005) and fasting blood glucose ( χ 2 =16.295, P < 0.001); further pairwise comparison showed that Child-Pugh class C liver cirrhosis patients with diabetes had a significantly lower GA% than Child-Pugh class A/B patients ( P < 0.05) and Child-Pugh class A patients had a significantly lower fasting blood glucose level than Child-Pugh class B patients ( P < 0.05). The fitting curve showed that GA% increased with the increase in CTP score in the liver cirrhosis patients without diabetes, reached the highest value at the CTP score of 6.5, and then started to decrease, with the lower value at the CTP score of 11.5, which showed a curvilinear relationship; in the liver cirrhosis patients with diabetes, GA% first increased and then decreased with the increase in CTP score, with a cut-off value of 8. Conclusion GA% first increases and then decreases along with the progression of liver cirrhosis. There is a significant difference in GA between liver cirrhosis patients with different Child-Pugh classes, suggesting that the reduction in GA is closely associated with liver function decompensation in end-stage liver cirrhosis.

Objective To investigate the clinical effect of direct-acting antiviral agent (DAA) in the treatment of chronic hepatitis C (CHC) patients with thrombocytopenia and its effect on platelet count (PLT). Methods A retrospective analysis was performed for 83 CHC patients with thrombocytopenia (PLT < 150×10 9 /L) who received the DAA treatment regimen without interferon for 12-24 weeks in Tianjin Third Central Hospital from April 2018 to March 2019, and the changes in virologic response, liver function parameters, PLT, and liver stiffness measurement (LSM) were evaluated at the end of treatment (EOT) and at week 12 after EOT. Quantitative data accord with normal distribution were compared by repeated measures ANOVA. Normal transformation was performed before the comparison between skewed data, then repeated measures ANOVA was carried out. A logistic regression analysis was used to investigate the predictive factors for PLT elevation, and the receiver operating characteristic (ROC) curve was plotted to analyze the value of LSM in predicting PLT elevation after treatment. Results Among the 83 CHC patients with thrombocytopenia, 61.4% had liver cirrhosis, and the rate of sustained virologic response at week 12 after the end of treatment (SVR12) was 98.8%. From baseline to EOT and SVR12, the patients had significant reductions in the serum levels of aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transpeptidase, total bilirubin, and globin, a significant increase in the serum level of albumin, and a significant reduction in LSM (all P < 0.05). For all patients, PLT at EOT and SVR12 was significantly higher than that at baseline [EOT vs baseline: (110.4±44.6)×10 9 /L vs (97.8±33.2)×10 9 /L, P < 0.01; SVR12 vs baseline: (109.0±47.7)×10 9 /L vs (97.8±33.2)×10 9 /L, P < 0.01]. At SVR12, there were significant differences in the proportion of patients with liver cirrhosis, baseline LSM, and baseline white blood cell count between the PLT elevation group and the non-PLT elevation group (all P < 0.05). The multivariate logistic regression analysis showed that LSM was an independent predictive factor for significant PLT elevation after DAA treatment (odds ratio=0.929, 95% confidence interval: 0.864-0.999, P < 0.05). Baseline LSM had an area under the ROC curve of 0.644 in predicting PLT elevation, with a sensitivity of 81.0% and a specificity of 48.6% at a cut-off value of 20.15 kPa. The patients with PLT > 100×10 9 /L at baseline had a greater increase in PLT( P < 0.05). Conclusion CHC patients with thrombocytopenia have significant improvements in liver function and LSM after receiving DAA treatment and obtaining SVR12, and baseline LSM is an independent predictive factor for PLT elevation. There is a significant increase in PLT from baseline to EOT and SVR12.

Wnt5a is a secreted Wnt ligand that plays a critical role in cellular pathways and inflammatory diseases. The WNT5A gene encodes two protein isoforms, Wnt5a-long and Wnt5a-short, which differ based on different promoter methylation and have distinct functions. However, the mechanisms of the promoter methylation are unclear. Depending on the extent of promoter methylation, Wnt5a exerts both anti-inflammatory and pro-inflammatory effects in inflammatory diseases, which may be involved in different Wnt5a isoforms. Therefore, the Wnt5a isoforms may be potential diagnostic markers for inflammatory diseases and the mechanisms of the WNT5A gene promoter methylation need to be further investigated.

Objective:To analyze the risk factors of death within two years of the patients with liver cirrhosis after transjugular intrahepatic portosystemic shunt(TIPS), and to explore the predictive value of 6 common clinical evaluation systems on the risk of death after TIPS.Methods:TIPS clinical data from 132 patients with liver cirrhosis were analyzed retrospectively. According to the 2-year clinical outcome after TIPS, the patients were divided into the death group and the survival group. Logistic regression was used to analyze the risk factors of death within 2 years after TIPS. According to the scores of CTP, MELD, MELD Na, BioCliM, FIB-4, and ALBI evaluation systems, the prediction efficiency of death risk of the six evaluation systems was evaluated by using the receiver operating characteristic (ROC) curves and the area under the curve (AUC).Results:During the 2-year follow-up period after TIPS, the age, urea nitrogen level, platelet count, and proportion of hepatic encephalopathy in the death group were higher than those in the survival group one month after TIPS, and the serum sodium level was lower than those in the survival group (all P<0.05). Multivariate analysis showed that the elderly and hepatic encephalopathy one month after operation were independent risk factors for death (all P<0.05). At 1 week after the surgery, there were significant differences in CTP, MELD, and MELD-Na scores between the survival group and the death group (all P<0.05). One week after operation, the AUC of ROC of CTP, MELD, MELD-Na, and ALBI scores were 0.685, 0.721, 0.805, and 0.658 respectively, and the optimal critical values were 8.5, 12.99, 14.51 and -1.52 respectively. Conclusions:The elderly and the occurrence of hepatic encephalopathy one month after TIPS are independent risk factors for the death of liver cirrhosis patients after TIPS. The evaluation of CTP, MELD, MELD-Na, and ALBI one week after TIPS can predict the death risk of decompensated liver cirrhosis patients within 2 years after TIPS, and MELD-Na has the best predictive effect.

Objective:To explore the efficacy and safety of ticagrelor versus clopidogrel in acute coronary syndrome (ACS) Chinese patients using glycoprotein Ⅱb/Ⅲa inhibitor (GPI).Methods:The data from CCC-ACS (Improving Care for Cardiovascular Disease in China-ACS) project were systematically reviewed in ACS patients with GPI. The patients were divided into ticagrelor and clopidogrel groups. A logistic analysis and propensity score matching (PSM) were performed to compare occurrences of major cardiovascular events (MACE) and bleeding events between the two groups during hospitalization.Results:A total of 63 641 ACS patients were collected from 150 hospitals. Logistic regression analyses showed that there was no statistically significant difference in the reduction of MACE between ticagrelor and clopidogrel when using GPI ( OR=0.881, 95% CI 0.599-1.296; P=0.521). However, major bleeding rate was higher in the ticagrelor group than that in the clopidogrel group ( OR=1.401, 95% CI 1.075-1.852; P=0.013). Similar results were observed after PSM. No statistic difference in MACE between the ticagrelor and clopidogrel group ( OR=0.919, 95% CI 0.613-1.376; P=0.681). Major bleeding rate was higher in the ticagrelor group ( OR=1.559, 95% CI 1.130-2.150; P=0.007). Conclusion:In ACS patients with GPI, ticagrelor did not reduce MACE, but increased the major bleeding risk compared with clopidogrel.

The incidence of metabolic rheumatism gout has been increasing with a trend of more younger patients and atypical symptoms. Typical gout is easy to be diagnosed, but it is difficult for atypical cases. Finding uric acid crystal in articular fluid by polarizing light microscope is a gold standard of diagnosis, but it is an invasive diagnostic method and difficult to be widely used. The patients need further imaging examination for assistance of diagnosis and guide of follow-up treatment. This article reviews the research progress of different imaging methods used for diagnosis of gouty arthritis.

Objective To investigate the effect of sarcopenia on the skeletal muscle and cardiac function in elderly patients with chronic heart failure (CHF).Methods Sixty patients with CHF and sarcopenia and 60 sex and age-matched CHF patients without sarcopenia were enrolled from September 2014 to December 2015.The skeletal mass was evaluated by fat-free mass index (FFMI) and muscle function was evaluated by gait speed (GS),hand strength (HS) and the simple physical performance battery (SPPB).The cardiac function was accessed by a 6-min walk distance (6-MWD) and left ventricular ejection fraction (LVEF).Furthermore,the serum inflammation cytokines IL-6,TNF-α,and skeletal muscle biomarker C 1q were measured.Results The CHF patients with sarcopenia had lower values for skeletal muscle mass:FFMI [(17.68±0.74) vs.(18.34±0.54)kg/m2,F=33.696,P＜0.05] and lower muscle function:HS [(17.26±4.20)vs.(28.85±6.43)kg,F=136.54,P＜0.05],GS [(0.65±0.11) vs.(0.90±0.10)m/s,F=-12.922,P＜0.05],SPPB [(6.45±2.07) vs.(7.65± 1.76),t=-3.452,P＜0.05].And the cardiac function decreased significantly in patients with sarcopenia:6-MWD [(253.76 ± 72.62) vs.(340.91 ± 55.78)m,F=54.350,P＜0.05],LVEF [(39.12 ± 7.02)vs.(43.83±5.81)％,t=16.060,P＜0.05].Serum IL-6/TNF-α/C1q levels were significantly elevated:IL-6[(14.12± 1.40) vs.(13.46±1.06) ng/L,F=8.513,P＜0.05],TNF-α [(443.43±28.06) vs.(299.37±21.53)ng/L,t=31.556,P＜0.05],C1q[(578.92±23.63) vs.(504.1 1±41.77)ng/L,F=145.78,P＜0.05].Conclusion The CHF patients with sarcopenia present less skeletal muscle mass,poorer skeletal function and reduced cardiac function,and higher inflammation levels.

Objective To explore the effect of short-term intensive rehabilitation training on respiratory function, motor function and the life quality of patients with obstructive sleep apnea combined with chronic obstruc-tive pulmonary disease ( OSA-COPD) . Methods Fifty-seven patients with OSA-COPD were randomly divided in-to an observation group and a control group. Both groups were treated with non-invasive positive pressure ventilation ( NPPV) , oxygen therapy and a bronchodilator, while the observation group was additionally provided with 8 weeks of intensive lung rehabilitation training, including respiratory function training and limb exercise training. Polysom-nography was used to monitor the apnea hyponea index ( AHI) , the lowest oxygen saturation level during the night ( LowSpO2 ) and the nocturnal oxygen saturation ratio for ＜ 90% of total sleep time ( tst90) . Arterial blood gases, forced vital capacity ( FVC) and forced expiratory volume in one second ( FEV1 ) were measured. The 6-minute walk test (6MWT) and St. George's respiratory questionnaire ( SGRQ) were used to evaluate all the patients before and after the intervention. Results After 8 weeks of treatment, the average AHI, LowSpO2 , TST90 and PaO2 had improved significantly in both groups. There was no significant difference between them. After the treatment the average FVC, FEV1 and 6MWT time of the observation group were significantly better than before the treatment and the significantly better than the control group's averages. After treatment, the average SGRQ score and activity abili-ty score of the observation group were also significantly improved and significantly better than the control group's av-erages. Conclusions NPPV can effectively improve OSA-COPD patients'tolerance of short-term intensive pulmo-nary rehabilitation training. With that assistance, short-term intensive rehabilitation training can promote the recov-ery of respiratory function and motor function, and improve the life quality of patients. Therefore, such therapy is worthy of clinical promotion and application.

Objective To explore the effect of pulmonary rehabilitation training on the respiratory function,motor function,life quality,survival and complications of patients with non-operative lung cancer.Methods A group of 88 patients with non-operative lung cancer was randomly divided into a training group (n=45) and a control group (n=43).Both groups were given anti-tumor therapy,while the training group was additionally provided with systematic respiratory training,including breathing pattern training,cough and expectoration training,respiratory gymnastics and walking training.Forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1) were measured at the outset and after 8,16 and 24 weeks of the training.The 6-minute walk test (6MWT) was administered along with the QLQ-C30 assessment of the European Organization for Research and Treatment of Cancer.Complications in both groups were also recorded and analyzed.The progression-free survival (PFS) and overall survival (OS) were followed up after the treatment.Results After 8,16 and 24 weeks of the treatment,the average FVC and FEV1 volumes and the 6MWT times of the training group were significantly better than those before treatment and significantly better than the control group averages.Indeed,no significant improvement was observed in the control group's average FVC,FEV1 or 6MWT results.After 24 weeks the treatment group's average scores on the physical function,social function,emotional function,fatigue,nausea and vomiting,pain,dyspnea,insomnia,appetite,constipation,and overall quality of life sub-scales of the QLQ-C30 had all improved significantly more than in the control group.The incidence of pulmonary complications in the control group (26％) was significantly higher than that in the training group.(11％).The median PFS and OS of the training group (14.3 and 27.3 months) were not significantly better than those of the control group,however.Conclusion Respiratory exercise training and aerobic exercise training combined with the anti-tumor therapy,while not prolonging survival,can effectively improve the life quality of patients with non-operative lung cancer,reducing the incidence of complications and promoting the recovery of respiratory function.The combination is worthy of popularization in clinical practice.
