ABSTRACT

ObjectiveTo assess the coverage and effectiveness of COVID-19 vaccines in the elderly. MethodsThis study was conducted in Changning District of Shanghai, targeting people aged 60 years and above. Vaccination data between 21 December 2020 and 28 February 2022 was retrieved from the Shanghai Collective Immunization System. Information on confirmed cases of COVID-19 from March 2022 through May 2022 was collected from the National Notifiable Diseases Reporting System. Vaccine effectiveness was calculated using the screening method. ResultsAs of 28 February 2022, 69.89% of people aged ≥60 years had received ≥1-dose vaccine, 63.80% had received full primary vaccination and 31.91% had received a booster dose. Vaccination coverage declined over age, with the lowest coverage in the elderly aged ≥80 years. Moreover, COVID-19 vaccination provided the highest protection against severe/critical illness and death due to the Omicron variants in the elderly aged ≥60 years. Full primary vaccination showed 96.15%(95%CI:84.15‒99.06)of vaccine effectiveness and booster vaccination showed 100% of the effectiveness against severe/critical COVID-19 and death. ConclusionsFull primary and booster vaccination coverage in the elderly is low, especially in those aged 80 and above. Our study finds high protection against COVID-19 associated severe/critical illness and death from both full primary and booster vaccination of inactivated COVID-19 vaccines in the elderly aged ≥60 years.

ABSTRACT

Objective:To investigate the effect and regulation of umbilical cord-derived mesenchymal stem cells (UC-MSCs) on islets function and NOD-like receptor family, pyrin domain containing 3 (NLRP3) and autophagy in type 2 diabetic mellitus (T2DM) mice.Methods:Experimental study. Twenty, 8-week-old, male C57BL/6J mice were selected and divided into a normal control group ( n=5) and a high-fat feeding modeling group ( n=15). The model of T2DM was established by high-fat feeding combined with intraperitoneal injection of low-dose streptozotocin. After successful modeling, those mice were divided into a diabetes group ( n=7) and a UC-MSCs treatment group ( n=7). The UC-MSCs treatment group was given UC-MSCs (1×10 6/0.2 ml phosphate buffer solution) by tail vein infusion once a week for a total of 4 weeks; the diabetes group was injected with the same amount of normal saline, and the normal control group was not treated. One week after the treatment, mice underwent intraperitoneal glucose tolerance tests and intraperitoneal insulin tolerance tests, and then the mice were sacrificed to obtain pancreatic tissue to detect the expressions of interleukin-1β (IL-1β) and pancreatic and duodenal homeobox 1 (PDX-1) by immunofluorescence. The bone marrow-derived macrophages were stimulated with lipopolysaccharide and adenosine triphosphate (experimental group) in vitro, then co-cultured with UC-MSCs for 24 h (treatment group). After the culture, enzyme-linked immunosorbent assay was used to detect the secretion level of IL-1β in the supernatant, and immunofluorescence staining was used to detect the expression of NLRP3 inflammasome, and related autophagy proteins. Statistical analysis was performed using unpaired one-way analysis of variance, repeated measure analysis of variance. Results:In vivo experiments showed that compared with the diabetes group, the UC-MSCs treatment group partially repaired islet structure, improved glucose tolerance and insulin sensitivity (all P<0.05), and the expression of PDX-1 increased and IL-1β decreased in islets under confocal microscopy. In vitro experiments showed that compared with the experimental group, the level of IL-1β secreted by macrophages in the treatment group was decreased [(85.9±74.6) pg/ml vs. (883.4±446.2) pg/ml, P=0.001], the expression of NLRP3 inflammasome and autophagy-related protein P62 was decreased, and the expressions of microtubule-associated protein 1 light chain 3β (LC3) and autophagy effector Beclin-1 were increased under confocal microscopy. Conclusions:UC-MSCs can reduce the level of pancreatic inflammation in T2DM mice, preserving pancreatic function. This might be associated with the ability of UC-MSCs to inhibit the activity of NLRP3 inflammasomes in macrophages and enhance autophagy levels.

ABSTRACT

Objective:To explore the effects of different initial flow rates of humidified high flow nasal cannula oxygen therapy on weaning outcomes and comfort level among ICU patients with difficult weaning.Methods:A total of 99 ICU patients with difficult weaning received at Guangzhou Red Cross Hospital ICU from June 2019 to June 2021 were enrolled in the present study, they were assigned to 40 L/min group, 50 L/min group and 60 L/min group according to the random number table method, with 33 cases in each group. The weaning outcomes among three groups were compared, the degree of dryness of oral/nasal cavity, throat pain as well as vital signs and blood gas indexes were also compared before extubation and 30 min after the first humidified high flow nasal cannula (HHFNC) oxygen therapy.Results:There was no significant difference in length of stay in ICU and hospital, re-intubation within 7 days, the mortality within 28 days in ICU and the hospital among three groups ( P>0.05). The weaning success rate were 78.8% (24/33) and 77.4% (23/31) in 50 L/min group and 60 L/min, higher than in the 40 L/min group 53.1% (17/32), the difference was statistically significant ( χ2=4.78, 4.09, both P<0.05). After oxygen therapy, the scores of dryness of oral/nasal cavity and throat pain in the 40 L/min group, 50 L/min group and 60 L/min group were (3.16 ± 0.77), (2.94 ± 0.80) and (3.27 ± 0.92), (3.09 ± 0.77), and (4.10 ± 1.01), (3.97 ± 1.40), the differences were statistically significant ( F=5.21, 9.26, both P<0.05), and the differences between 50 L/min group and 40 L/min group and 60 L/min group were statistically significant ( t values were 2.62-3.99, all P<0.05). However, there was no significant difference in vital signs and blood gas indexes among the three groups before extubation and after oxygen therapy ( P>0.05). Conclusions:Humidified high flow nasal cannula oxygen therapy for the ICU patients with difficult weaning, oxygen flow with 50L/min can not only effectively promote weaning success rate but also improve patients′ respiratory comfort level.

ABSTRACT

OBJECTIVE@#To investigate the effects of different manners of heat exposure on thoracic aorta injury in spontaneously hypertensive rats (SHRs) and explore the underlying mechanism.@*METHODS@#Normal 6 to 7-week-old male SHRs were randomized into control group (cage at room temperature), intermittent heat exposure group (SHR-8 group, exposed to 32 ℃ for 8 h daily for 7 days) and SHR-24 group (with continuous exposure to 32 ℃ for 7 days). After the treatments, the pathologies of the thoracic aorta of the rats were observed with HE staining, and the expressions of Beclin1, LC3B and p62 were detected with Western blotting and immunofluorescence assay; TUNEL staining was used to observe cell apoptosis in the thoracic aorta, and the expressions of caspase-3, Bax, and Bcl-2 were detected using Western blotting. The effects of intraperitoneal injections of 3-MA (an autophagy agonist), rapamycin (an autophagy inhibitor) or compound C 30 min before intermittent heat exposure on the expressions of proteins associated with autophagy, apoptosis and the AMPK/mTOR/ULK1 pathway in the aorta were examined with immunohistochemistry.@*RESULTS@#In SHR-8 group, the rats showed incomplete aortic intima with disordered cell distribution and significantly increased expressions of Beclin1, LC3II/LC3I and Bax, lowered expressions of p62 and Bcl-2, and increased apoptotic cells in the thoracic aorta (P < 0.05). Pretreatment with 3-MA obviously inhibited the expressions of autophagy- and apoptosis-related proteins, whereas rapamycin promoted their expressions. Compared with the control group, the rats in SHR-8 group had significantly down-regulated p-mTOR and up-regulated p-AMPK and p-ULK1 expression of in the aorta; Treatment with compound C obviously lowered the expressions of p-AMPK and p-ULK1 and those of LC3B and Beclin1 as well.@*CONCLUSION@#In SHRs, intermittent heat exposure causes significant pathologies and promotes autophagy and apoptosis in the thoracic aorta possibly by activating the AMPK/mTOR/ULK1 pathway.

ABSTRACT

【Objective:】 To understand the current status of narrative nursing knowledge, attitude, and practice (KAP) among nurses in grade A tertiary hospitals, and to provide a basis for the development of narrative nursing in relevant areas. 【Methods:】 Using convenience sampling methods, 931 nurses from three grade A tertiary hospitals in Xi’an were selected as subjects. A cross-sectional survey was conducted using the Clinical Nurses’ Narrative Nursing Knowledge and Trustworthiness Questionnaire and the General Self-Efficacy Scale. Multiple linear regression analysis was used to explore the influencing factors of nurses’ narrative nursing KAP. 【Results:】 The scores on the three dimensions of narrative nursing KAP were (23.70±2.99) points, (31.69±5.92) points, and (30.26±5.32) points, respectively. Nursing workload, general self-efficacy, professional title, and nursing satisfaction were the influencing factors of nurses’ narrative nursing knowledge dimension (P<0.05). There were statistically significant differences in nurses’ narrative nursing attitude dimension among nursing workload, general self-efficacy, professional title, monthly income, and nursing satisfaction (P<0.05). Nursing workload, general self-efficacy, nursing satisfaction, and accompanying experience were the influencing factors of nurses’ narrative nursing behavior dimension (P<0.05). 【Conclusion:】 Nurses in grade A tertiary hospitals have moderate narrative nursing knowledge, positive attitudes, and poor practice execution. The high nursing workload is the main barrier factor for the current development of narrative nursing. Nursing managers should actively build a diversified training system and guarantee system to boost the development of narrative nursing in clinical nursing work, and further promote the development of narrative nursing concepts.

ABSTRACT

AIM: To study the role and mechanism of curcumol in neovascularization induced by vascular endothelial growth factor(VEGF).METHODS: Human umbilical vein endothelial cells were cultured in vitro and treated with 50ng/mL VEGF and curcumol at different concentrations. Cell proliferation was detected by CCK-8 and EdU assay, the migration ability of cells was analyzed by Transwell assay, the angiogenesis ability of endothelial cells was analyzed by tube formation assay, and the change of Akt/mTORC1 signal pathway was detected by Western blot.RESULTS: CCK-8 results showed that the OD450 value of cells in 400 and 800 μmol/L curcumol+VEGF group was significantly lower than that in VEGF group(all P<0.01). EdU results showed that the rate of cell proliferation in 400 μmol/L curcumol+VEGF group was significantly lower than that in VEGF group(P<0.001). Transwell assay and the formation assay results showed that the number of migratory cells in 400 μmol/L curcumol+VEGF group was decreased, and the number and length of tube branches were also reduced compared with VEGF group(all P<0.001). Western blot results showed that curcumol significantly inhibited the expression of p-Akt and p-S6, which were downstream targets of Akt/mTORC1 pathway in cells.CONCLUSION: Curcumol can inhibit VEGF-induced cell proliferation, migration and tube formation of vein endothelial cells, and has a strong inhibitory effect on angiogenesis, which can be further studied in the treatment of ocular fundus neovascularization.

ABSTRACT

Objective:To explore the relationship between sleep status and the disease in children with recurrent vertigo(RVC) by analyzing the objective sleep condition of children with recurrent vertigo. Methods:According to the diagnostic criteria of RVC, 50 children with RVC and 20 normal controls without RVC were selected. According to the vertigo questionnaire score, the RVC group was divided into mild, moderate and severe groups according to severity. Continuous polysomnography(PSG) was performed for all participants, and SPSS 25.0 statistical software was used to analyze the monitoring results. Results:①There were significant differences in sleep time of each period, total sleep time and sleep efficiency between RVC group and control group(P<0.05), but there was no significant difference in sleep latency(P>0.05). The specific manifestations were that the proportion of sleep time in N1 and N2 phases increased, the proportion of sleep time in N3 and REM phases decreased, the total sleep time and sleep efficiency decreased in RVC group. ②The abnormal rate of sleep apnea hypopnea index, that is, the proportion of AHI≥5 times/h and the abnormal rate of lowest blood oxygen saturation in RVC group were higher than those in normal control group. There was significant difference between the two groups(P<0.05). ③There were significant differences in the proportion of AHI≥5 times/h and lowest SpO2 among mild group, moderate group and severe group(P<0.05). ④There was no significant correlation between the degree of vertigo and the abnormal rate of AHI in children with RVC, but there was a negative correlation between the degree of vertigo and the abnormal rate of lowest SpO2 in children with RVC. Conclusion:Children with RVC are often accompanied by sleep disorders, clinicians should pay attention to both the symptoms of vertigo and sleep condition in children. Polysomnography is non-invasive and operable, providing a new idea to the auxiliary examination of RVC in children. It is of certain clinical significance for the comprehensive treatment of children with RVC to actively improve vertigo symptoms and pay attention to improving sleep quality.

ABSTRACT

@#Objective To investigate the relationship between gait spatiotemporal parameters and balance function in stroke hemiplegic patients. Methods From September, 2018 to March, 2020, 76 stroke hemiplegic patients (38 in Brunnstrom Ⅳ and V, respectively) were assessed balance function with Active Balancer EAB-100 and Star Excursion Balance Test (SEBT), and gait parameters of speed, cadence and asymmetry, named step length asymmetry ratio (SLA), swing time asymmetry ratio (SWTA), stance time asymmetry ratio (STA), maximum flexion angle ratio (MFA) of hip and knee. The correlation among gait parameters and balance function was analysed. Results The balance and gait parameters were better in those in Brunnstrom V than in Brunnstrom Ⅳ (|t| > 2.268, P < 0.05). The speed and cadence correlated with the most balance indexes (|r| > 0.335, P < 0.05). SLA correlated with SEBT in Brunnstrom Ⅳ patients (r = -0.467~-0.613, P < 0.01), while it correlated with medial-lateral (M-L) stability limits in Brunnstrom V patients (r = -0.356, P = 0.028). SWTA correlated with stability limit of Anterior-Posterior (A-P) (r = -0.335, P = 0.040) and M-L (r = 0.510, P = 0.001), and most of SEBT (r = -0.330~ -0.445, P < 0.05) in Brunnstrom Ⅳ patients. MFA of hip and knee correlated with balance indexes in Brunnstrom Ⅳ patients (|r| > 0.326, P < 0.05), while MFA of knee correlated with most balance indexes in Brunnstrom V patients (r > 0.329, P < 0.05), and MFA of hip correlated with A-P stability limit (r = 0.369, P = 0.023). Conclusion Both speed and cadence of steps can well respond to the balance function in stroke hemiplegic patients. For the asymmetry, it is related with balance in patients with poorer recovery.

ABSTRACT

By consulting ancient Chinese herbal medicines and medical books, the textual research of Armeniacae Semen Amarum has been conducted to verify the name, origin, producing area, quality evaluation, harvesting and processing changes. Through textual research, Shennong Bencaojing began to contain Xinghe. After Xinxiu Bencao, Xingheren were gradually taken as the mainstream name, Xingren was first used as the correct name since Leigong Paozhilun, and gradually became the mainstream rectifying in the Ming and Qing dynasties. Before the Qing dynasty, there was no distinction between Armeniacae Semen Amarum and Armeniacae Semen Dulcis in the materia medica works, while the differences between them were clearly defined in some works of the Qing dynasty, but did not record them separately. In order to make them more accurate in clinical application, Armeniacae Semen Amarum was recorded as the correct name in the 1953 edition of Chinese Pharmacopoeia, and Armeniacae Semen Dulcis was included in the provincial standards. The original plants of Armeniacae Semen Amarum from Prunus armeniaca (Armeniaca vulgaris in Flora of China) and its cultivated varieties with bitter seeds were taken as the mainstream, which are reflected in the Chinese Pharmacopoeia. Its yellow ripe fruit was generally harvested in May, the seed kernel was taken out for drying or baking, finally the seed coat was removed to use. It is recorded that the production area of Armeniacae Semen Amarum is Taihang Mountain area of Shanxi province in ancient times. At present, its producing area is mainly concentrated in Shanxi, Shandong, Hebei and other places in north China. Historical literature pointed out that Armeniacae Semen Amarum had small toxicity, and heat treatment could reduce toxicity and increase efficiency, its main processing method was blanching and stir-frying. In addition, it is generally believed that raw products with seed coat can enhance its sweating effect since the Ming and Qing dynasties. Until now, three processed products are stipulated in the Chinese Pharmacopoeia, namely raw products, boiled and fried products. Based on textual research, it is recommended that A. vulgaris should be used as the original plant of Armeniacae Semen Amarum in famous classical formulas, and the use of processed products should follow the processing requirements marked in the formulas.

ABSTRACT

BACKGROUND@#The global pandemic coronavirus disease 2019 (COVID-19) has become a major public health problem and presents an unprecedented challenge. However, no specific drugs were currently proven. This study aimed to evaluate the comparative efficacy and safety of pharmacological interventions in patients with COVID-19.@*METHODS@#Medline, Embase, the Cochrane Library, and clinicaltrials.gov were searched for randomized controlled trials (RCTs) in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)/SARS-CoV. Random-effects network meta-analysis within the Bayesian framework was performed, followed by the Grading of Recommendations Assessment, Development, and Evaluation system assessing the quality of evidence. The primary outcome of interest includes mortality, cure, viral negative conversion, and overall adverse events (OAEs). Odds ratio (OR) with 95% confidence interval (CI) was calculated as the measure of effect size.@*RESULTS@#Sixty-six RCTs with 19,095 patients were included, involving standard of care (SOC), eight different antiviral agents, six different antibiotics, high and low dose chloroquine (CQ_HD, CQ_LD), traditional Chinese medicine (TCM), corticosteroids (COR), and other treatments. Compared with SOC, a significant reduction of mortality was observed for TCM (OR = 0.34, 95% CI: 0.20-0.56, moderate quality) and COR (OR = 0.84, 95% CI: 0.75-0.96, low quality) with improved cure rate (OR = 2.16, 95% CI: 1.60-2.91, low quality for TCM; OR = 1.17, 95% CI: 1.05-1.30, low quality for COR). However, an increased risk of mortality was found for CQ_HD vs. SOC (OR = 3.20, 95% CI: 1.18-8.73, low quality). TCM was associated with decreased risk of OAE (OR = 0.52, 95% CI: 0.38-0.70, very low quality) but CQ_HD (OR = 2.51, 95% CI: 1.20-5.24) and interferons (IFN) (OR = 2.69, 95% CI: 1.02-7.08) vs. SOC with very low quality were associated with an increased risk.@*CONCLUSIONS@#COR and TCM may reduce mortality and increase cure rate with no increased risk of OAEs compared with standard care. CQ_HD might increase the risk of mortality. CQ, IFN, and other antiviral agents could increase the risk of OAEs. The current evidence is generally uncertain with low-quality and further high-quality trials are needed.

ABSTRACT

Objective:To explore the risk factors of thyroid nodules in diabetic patients and its correlation with Traditional Chinese Medicine (TCM) constitution.Methods:A Total of 213 cases of diabetic patients in Guang’anmen Hospital and Tangshan Hospital from January 2019 to August 2020 were choosen to do the questionnaire, with containly symptom and constitution. The patients were divided into diabetes with thyroid nodules group and diabetes without thyroid nodules group according to whether thyroid nodules were combined. We compared the clinical data characteristics of 2 groups, and used multi-factor logistic regression model to analyze the risk factors of diabetic patients with thyroid nodules and their correlation with TCM constitutions. Results:Diabetes patients aged from 50-80 years old [ OR=2.949, 95% CI (1.266-6.714)], females [ OR=3.736, 95% CI (1.823-1.541)], diabetes duration≥15 years [ OR=1.558, 95% CI (1.623-1.585)], elevated HbA1c [ OR=5.862, 95% CI (1.418-23.629)], elevated VLDL [ OR=2.851, 95% CI (1.597-6.824)], frequent insomnia [ OR=1.970, 95% CI (1.315-3.395)], Qi stagnation [ OR=4.357, 95% CI (2.634-8.377)], blood stasis [ OR=4.420, 95% CI (1.874-15.258)] are more likely to suffer from thyroid nodules ( P<0.05). Conclusion:Diabetic patients aged from 50-80 years old, females, diabetes duration≥15 years, elevated HbA1c, family history of thyroid nodules, frequent insomnia, and mood swings are more likely to develop thyroid nodules; qi stagnation and blood stasis are dangerous constitutions for diabetic patients with thyroid nodules.

ABSTRACT

OBJECTIVES@#Hypertension is a serious complication of pregnancy-related acute kidney injury (PR-AKI). This study aimed to determine the effect of hypertension on the prognosis of PR-AKI, maternal outcomes, and fetal outcome.@*METHODS@#Patients with PR-AKI in a hospital from January 2008 to June 2018 were enrolled for this study. Patients with or without hypertension were grouped by 1꞉1 propensity matching score. The effect of hypertension on the prognosis of PR-AKI was evaluated by multivariate Cox regression before and after matching.@*RESULTS@#Of the 30 680 women who attended the Department of Obstetrics, 126 patients were diagnosed as PR-AKI, the incidence was 0.41%. The age was (29.04±2.32) years. There were 50 cases in the hypertension group, accounting for 39.68%. Using the propensity score method, 48 pairs of patients were successfully matched, and the covariates between the two groups were balanced. After matching and adjusting for relevant clinical factors, Cox regression analysis showed that risk of end-stage renal disease (ESRD) was increased in the hypertension group compared with the normal blood pressure group (HR=2.951, 95% CI 1.067 to 8.275, =0.034). The risk of risk of adverse maternal outcome was increased (HR=2.815, 95% CI 1.271 to 6.233, =0.009), and the risk of fetal adverse outcome was increased (HR=1.437, 95% CI 1.028 to 4.623, =0.021).@*CONCLUSIONS@#Hypertension is an independent risk factor for ESRD, adverse maternal outcomes, and adverse fetal outcomes in the PR-AKI patients.

ABSTRACT

Artemisiae Argyi Folium, the dried leaves of Artemisia argyi, has been widely used in traditional Chinese and folk medicines for a long time. Qiai is one of the top-geoherb of Artemisiae Argyi Folium. Qiai contains various bioactive constituents, such as volatile oils, phenolic acids, flavonoids and terpenoids. Phytochemical studies demonstrated that volatile compounds are the main bioactive constituents in Qiai. Try to investigate dynamic changes of volatile components of Qiai from different harvest time and explore the optimum harvest time of Qiai, in this study, the contents of total volatile oils in Qiai collected from five different harvest time were analyzed by steam distillation method. The results showed that the contents of volatile oils of Qiai were higher in the third harvest time(around the Dragon Boat Festival), which is basically consistent with the traditional harvest time. Furthermore, a sensitive method based on gas chromatography-mass spectrometry(GC-MS) was established for qualitative analysis of volatile compounds in Qiai, and a total of thirty volatile compounds were identified. Chemometrics methods including principal component analysis(PCA) and orthogonal partial least-squares discriminate analysis(OPLS-DA) were applied to explore chemical markers and dynamic changes of volatile components in Qiai from different harvest time, and the results indicated that there were obvious differences in the relative contents of volatile compounds of Qiai samples from different harvest time. Eight volatile compounds, including α-terpinene, γ-terpinene, D-camphor, trans-carveol, α-copaene, isobornylisobutyrate, humulene, and caryophyllene oxide were selected as potential chemical markers. Among the eight chemical markers, the relative contents of α-terpinene, γ-terpinene, α-copaene and caryophyllene oxide were higher in the third harvest period(around the Dragon Boat Festival), which is consistent with the contents of total volatile oils. The present study could provide the basis for investigating the optimum harvest time of Qiai, and might be useful for the quality control of this herbal medicine.

ABSTRACT

Objective To investigate the effect of picropodophyllin (PPP) on proliferation and cell cycle of human colorectal cancer cell line HCT-15 and to clarify the related mechanism. Methods Different concentrations of PPP were used to treat HCT-15 cells, the proliferative activity of HCT-15 cells was detected by cell courting kit-8(CCK-8). Morphological changes of HCT-15 cells were observed under inverted microscope. Flow cytometry was used to detect the changes of HCT-15 cell cycle and Western blotting was used to detect the expression of proliferating cell nuclear antigen (PCNA) and cell cyclinD1. Results The result of CCK-8 assay showed that PPP inhibited the proliferation of HCT-15 cells in a dose-time-dependent manner. Under the inverted microscope, it was found that the HCT-15 cells lost their original shape and became round, the refractive index decreased, and the number of living cells decreased significantly. Flow cytometry showed that the proportion of G

ABSTRACT

Purpose To identify the significance of different expression localization of β-catenin and its correlation with clinical pathological parameters in gastric cancer (GC) . Methods The expression of β-catenin proteins in 120 gastric cancer and 50 normal gastric mucosa samples was detected by SP immunohistochemistry. Results The positive expression of β-catenin was localized to membrane with positive rate 100. 00% in normal gastric mucosa. Lack of β-catenin membrane expression and ectopic expression in cytoplasm,nuclei,or cytoplasm/nuclei were found in GC tissue and the abnormal expression rate was as high as 81. 67% (98/120) . The abnormal expression of β-catenin was significantly correlated with histological differentiation,lymphatic metastasis and TNM stage in GC (P < 0. 05) . The nuclear expression rate of β-catenin was 36. 67% (44/120) ,and the positive nuclear expression was significantly correlated with TNM stage in GC (P < 0. 05) . The 5-year overall survival rate of β-catenin nuclear positive patients was significantly lower than that of nuclear negative ones (P < 0. 05) . Conclusion β-catenin plays a significant role in gastric cancer carcinogenesis,and its different expression localization is related to the progress of GC. β-catenin is expected to be a potential target for diagnosis and treatment of GC.

ABSTRACT

Objective To evaluate the clinical efficacy of domestic sulfasalazine (SASP) combined with probiotics on the treatment of inflammatory bowel disease (IBD).Methods According to the search of Chinese periodical full-text database,PubMed and other Chinese databases as well as English databases,the cases of IBD treated with SASP combined with probiotics or metronidazole in China were collected and screened for randomized controlled trials (RCT).The results between combined group and control group were compared using odds ratio (OR) and 95% Confidence Interval (CI) indicates.The evaluation indicator was the remission rate.According to the inclusion and exclusion criteria,the literature was selected,and data was extracted.Quality assessment of the included methodologies was performed,and RevMan 5.3 software was used for meta-analysis.Results 26 studies including a total of 2 403 patients were adopted in the present study.Among them,13 studies suggested that the remission rate of IBD in SASP combined with probiotics group was significantly improved compared with that in the SASP group alone (x2 =10.29,df =12,I2 =0%,P <0.05,the effect model OR =3.70,95% CI as 2.62-5.21),demonstrating that the combined treatment was superior to monotherapy in IBD.10 studies suggested that the remission rate of ulcerative colitis (UC) in SASP combined with probiotics group was significantly improved compared with that in the SASP group alone (x2 =2.59,df =9,I2 =0%,P < 0.05,the effect model OR =3.84,95% CI as 2.52 -5.86),demonstrating that the combined treatment was superior in UC.The other 3 studies showed that the remission rate of UC with infection in SASP combined with probiotics group was significantly improved compared with that in SASP combined with metronidazole group (x2 =0.07,df =2,I2 =0%,P < 0.05,the effect model x2 =4.77,95% CI as 2.27-10.02),demonstrating that treatment of SASP combined with probiotics was superior in UC with infection.Conclusions SASP combined with probiotics can improve the effective response rate in the treatment of IBD.
