Objective We aim to objectively evaluate the influence of six-character formula on patients with stable chronic obstructive pulmonary disease (COPD).Methods The randomized controlled trials (RCTs) which investigated the influence of six-character formula on patients with COPD were electronically searched in the databases such as China National Knowledge Infrastructure (CNKI),Chinese Science Technology Periodical Databases (VIP),Wanfang Data,PubMed,The Cochrane Library (Issue 6,2014) and ELSEVIER.According to the inclusion and exclusion criteria,the references was screened,the data were extracted and the methodological quality of the included articles was assessed.Then,Meta-analy-sis was performed using RevMan 5.3 software.Results A total of 10 studies involved,578 patients were included.The result of Meta-analysis showed that compared with the control group,six-character formula significantly improved six-minute walk distance,forced expiratory volume in a second (FEV1) and FEV1 predicted value,reduced the score of activity limitation and the impact of the disease in St George's respiratory questionnaire (SGRQ).the value of MD and 95％CI were 22.62 (10.49-34.75),0.10 (0.01-0.18),3.08 (0.18-5.97),8.69 (4.09-13.83),7.60 (2.34-12.85).However,there was no statistical difference in the score of symptom.Conclusions Six-character formula plays a significant role in the treatment of stable COPD.However,more studies in large scale and high quality are needed to verify the result.

Objective: To investigate the effects of the link between overweight/obesity and type 2 diabetes mellitus (T2DM) on leptin and visfatin levels. Methods: Males without T2DM and male patients with T2DM hospitalized in Lishui Municipal Central Hospital from January to June, 2017 were enrolled. Subjects' age and medical history of diseases were collected. The height and body weight were measured, and the body mass index (BMI) was estimated. The leptin and visfatin levels were determined, and compared between patients with and without T2DM, and between patients with and without overweight/obesity. The effect of the link between overweight/obesity and T2DM on leptin and visfatin levels was examined using a generalized linear regression model. Results: There were 66 patients with T2DM, with a mean age of (49.70±9.45) years and a mean diabetes duration of (4.99±4.46) years, and there were 64 patients without T2DM, with a mean age of (43.89±0.20) years. The leptin [ (3.17±0.36) vs. (3.03±0.30) ng/mL; t=2.387, P=0.018] and visfatin levels [ (29.14±3.16) vs. (21.81±3.32) ng/mL; t=12.900, P<0.001] were significantly greater in T2DM patients than in patients without T2DM. The leptin level was significantly greater in patients with overweight/obesity than in those without overweight/obesity [ (3.27±0.32) vs. (2.92±0.26) ng/mL; t=6.634, P<0.001], and the visfatin level was significantly lower in patients with overweight/obesity than in those without overweight/obesity [(24.38±5.14) vs. (26.71±4.36) ng/mL; t=2.780, P=0.006]. Generalized linear regression analysis showed interacting effects of overweight/obesity and T2DM on leptin (β=0.286, P=0.003) and visfatin levels (β=2.709, P=0.008). Conclusion The interaction between overweight/obesity and T2DM affects leptin and visfatin levels.

Objective:To analyze the risk factors of acute kidney injury (AKI) in hospitalized patients with infective endocarditis (IE), construct prediction model, and discuss its predictive value.Methods:The clinical data of 402 adult inpatients diagnosed with IE admitted to the Affiliated Hospital of Qingdao University from January 2010 to January 2020 were retrospectively analyzed. The patients were divided into the AKI group and the non-AKI group. The clinical data, such as gender, age, presence of diabetes, basic estimated glomerular filtration rate (eGFR), laboratory indexes at admission, involvement of valves, presence of sepsis, medication during hospitalization, surgery and outcome of the two groups were compared. Multivariate Logistic regression analysis was used to screen the risk factors of AKI in IE inpatients. A predictive model was constructed, and receiver operating characteristic (ROC) curve was used to analyze the predictive value of the model.Results:A total of 290 patients with IE were enrolled, including 198 non-AKI patients and 92 AKI patients. The incidence of AKI was 31.7%. Among the 92 AKI patients, 46 patients were at AKI stage 1 (50.0%), while 46 patients were at AKI stage 2 and stage 3 (50.0%). Compared with the non-AKI group, patients in the AKI group were older [years old: 64 (55, 71) vs. 55 (46, 63)], and had lower basic eGFR (mL·min -1·1.73 m -2: 64.6±13.6 vs. 82.9±19.5), higher proportion of diabetic and incidence of sepsis (16.3% vs. 8.6%, 38.0% vs. 13.1%), more frequent use of angiotensin converting enzyme inhibitors/angiotensin Ⅱ receptor antagonists (ACEI/ARB), diuretics and non-steroidal anti-inflammatory drugs (NSAIDs; 25.0% vs. 15.2%, 82.6% vs. 63.1%, 58.7% vs. 24.2%), more abnormal urine test results (hematuria or proteinuria, 35.9% vs. 22.7%), higher pathogen culture negative rate (73.9% vs. 51.5%), lower Gram positive (G +) cocci infection rate and surgery rate (22.8% vs. 40.4%, 60.9% vs. 81.8 %), with significant differences (all P < 0.05). There were no significant differences in the gender, number and location of involved valves, and laboratory indexes at admission between the two groups. Compared with the non-AKI group, the inpatient mortality rate of the AKI group was higher (30.4% vs. 8.6%, P < 0.01), and the inpatient mortality rate of patients with AKI stage 2 and stage 3 was significantly higher than that of patients with AKI stage 1 (43.5% vs. 17.4%, P < 0.01). In multivariate Logistic regression analysis, the lower basic eGFR [hazard ratio ( HR) = 0.136, 95% confidence interval (95% CI) was 0.066-0.280], sepsis ( HR = 6.100, 95% CI was 2.394-15.543), demand for NSAIDs ( HR = 2.990, 95% CI was 1.184-7.546) and radiocontrast agent ( HR = 3.153, 95% CI was 1.207-8.238) were independent risk factors for AKI in hospitalized patients with IE (all P < 0.05). A prediction model was constructed based on the above risk factors, and ROC curve analysis showed that the area under the ROC curve (AUC) of prediction model for AKI was 0.888 (95% CI was 0.833-0.943, P < 0.01) with sensitivity of 86.4% and specificity of 80.9%. Conclusions:In the IE-susceptible population, low basic eGFR, sepsis, the need for NSAIDs and contrast agent are independent risk factors to AKI. The predictive model constructed by the above risk factors has certain predictive value for the occurrence of AKI in the IE inpatients.

Objective:To investigate the application of 3.0T high resolution magnetic resonance imaging(HR-MRI)in acute ischemic stroke(AIS)and the influence factors of prognosis.Methods:A total of 92 AIS patients who underwent treatment in Hainan General Hospital from January 2019 to June 2022 were selected as the research objects.All patients were treated by thrombolytic therapy,and they were divided into favorable prognosis group(mRS scores≤2 points,n=66)and poor prognosis group(mRS score>2 points,n=26)according to modified Rankin Scale after they received 90d treatment.All of patients underwent Magnetom Trio type of 3.0 T HR-MRI examination within 1 week after they hospitalized,and the changes of luminal stenosis rate,the luminal area at the narrowest point,the plaque load,T2WIsignal intensity index,T1WI signal intensity index,plaque enhancement rate and other parameters were compared.The receiver operating characteristics(ROC)curve was adopted to analyze the predictive value of 3.0T HR-MRI parameters on the AIS prognosis.Binary Logistic regression model was used to analyze the risk factors that affected the prognosis of AIS patients.Results:The difference of infarction diameter between two groups was statistically significant(x2=6.574,P<0.05).The lumen area at the narrowest point in the poor prognosis group was significantly lower than that in the favorable prognosis group,while the T2WI signal intensity index,T1WI signal intensity index and plaque enhancement rate in the poor prognosis group were significantly higher than those in the favorable prognosis group(t=-3.378,4.443,4.413,3.890,P<0.05),respectively.ROC curve analysis showed that the area under curve(AUC)values of T2WI signal intensity index,T1WI signal intensity index,lumen area at the narrowest point and plaque enhancement rate in predicting the AIS prognosis were respectively 0.743,0.739,0.706 and 0.748.The Logistic regression analysis showed that infarction diameter>3.0cm,T1WI signal intensity index,T2WI signal intensity index,lumen area at the narrowest point and plaque enhancement rate were respectively independent risk factors that could affect AIS prognosis(OR=3.889,257.151,105.073,4.091,1.121,P<0.05).Conclusion:3.0T HR-MRI has higher efficiency in the assessment for the prognosis of patients with AIS,which can provide guidance for the judgement of prognosis and the formulation of treatment scheme through observes the changes of a series of parameters include T2WI signal strength index,T1WI signal strength index,the lumen area at the narrowest point,plaque enhancement rate.The above parameters are risk factors that affect the prognosis of patients,which often represent the progress of patients'conditions.

Of these patients, 22 patients were treated with HA280 immunoadsorption column for three times (the immunoadsorption group) and 50 patients were treated with drugs only (the control group). The changes of clinical symptoms and signs, autoimmune antibodies, myocardial enzyme spectrum, the inflammatory markers [erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and ferritin], immunoglobulin, complement, other biochemical indexes and pulmonary images of the patients were detected and analyzed before and after the treatment. And then the data were analyzed by Chi-square test, samples t testand Wilcoxon rank sum test. Results:Compared with the control group, the symptoms and signs were obviously improved after treatment with HA280 immunoadsorption column. In particular, the clinical improvement rate of non-specific myositis (89%, 16/18) was higher than that of the control group [(58%, 22/38), χ2=5.379, P<0.05]. And the clearance of autoantibody (control group) was grade 39.41 in average, 28.38 in average in the immunoadsorption group( Z=-2.51, P=0.01), myocardial enzyme spectrum [control 717(1 564) U/L, immunoadsorption group 126(432) U/L , Z=3.09, P<0.01], the inflammatory markers such as ESR [the control group was 24(22) mm/1 h, the immunoadsorption group was 10(7) mm/1 h, Z=-3.0, P=0.003] and immunoglobulin G [the control group was 11(5) g/L, the immunoadsorption group was 9(2) g/L, Z=-4.8, P=0.001] and immunoglobulin M [the control group was 0.9(0.4) g/L, the immunoadsorption group was 1.2(0.8) g/L, Z=-2.0, P=0.05]. Moreover, the lung CT scan showed that pulmonary lesions of the patients in the immunoadsorption group (89%, 17/19) was much more improved than the control group [(61%, 27/44), χ2=4.98, P<0.05]. No serious adverse reactions occurred. Conclusion:HA280 immunoadsorption therapy can significantly clear the autoantibodies, decrease muscle enzymes, inflammatory markers and immunoglobulin, improve lung images of some patients in a short time. It has been shown that it is safein patients with IIM. HA280 immunoadsorption therapy could be an effective treatment for IIM.

There were statistically significant differences in the quality of life between the two groups, except for cognitive function, sleep and economic status ( P<0.05) . The satisfaction with the medical and nursing staff in the control group was 79.03% (49/62) lower than 92.45% (49/53) in the intervention group, and the difference between the two groups was statistically significant ( P<0.05) . Conclusions:The evidence-based bundled and continuing nursing measures can improve the compliance, quality of life and satisfaction with the medical nursing staff in patients undergoing the first chemotherapy after gastric cancer surgery.

OBJECTIVE：To investigate the effects of parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with patient controlled intravenous analgesia （PICA） on postoperative analgesia in patients undergoing gynecological laparoscopic surgery and its effect on serum related factors. METHODS ：A total of 280 patients who underwent gynecologic laparoscopic surgery in the Second Affiliated Hospital of Hainan Medical University from Mar. 2017 to Mar. 2019 were randomly divided into control group （group C ），parecoxib sodium group （group P ），and flurbiprofen axetil group （group F ）and lornoxicam group （group L ）acording to random number table ，with 70 patients in each group. Four groups of patients received Sodium chloride injection 5 mL，Parecoxib sodium for injection 40 mg，Flurbiprofen axetil injection 50 mg and Lornoxicam for injection 8 mg （added 8 mg when the effect was not good ）intravenously at 30 min before the end of surgery. At the end of surgery ，they were given PICA of Sufentanil citrate injection and Dizosin injection for analgesia. The situation of pain and nausea symptom were evaluated at 6，12，24 and 48 h after surgery by using numerical rating scale （NRS）. The levels of serum CRP ，IL-6，SP and PGE 2 were detected by chemiluminescence method and ELISA. The times of pressing PICA pump and the dosage of analgesic were recorded in 4 groups within 24 h after surgery. The ADRs of patients within 48 h after surgery were recorded ，such as bloating ， dizziness，itchy skin ，respiratory depression and urinary retention. RESULTS ：At different time points ，the NRS scores of pain of group P ，F and L were significantly lower than those of group C ；and 48 h after surgery ，NRS score of pain of group L was significantly lower than those of group P and F （P＜0.05）. There was no statistical significance in the level of CRP ，IL-6，SP and PGE2 of 4 groups before surger （P＞0.05）. The CRP ，IL-6，SP and PGE 2 levels at each time point after surgery of group P ，F and L were significantly lower than those of group C ；compared with group P ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12，24 and 48 h after surgery were significantly decreased in group F ，and serum level of IL- 6 at 48 h after surgery，serum levels of SP at 24 and 48 h after surgery ，serum levels of PGE 2 at 12，24，48 h after surgery were decreased significantly in group L ；compared with group F ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12， 24，48 h after surgery were all decreased significantly in group L （P＜0.05）. There was no statistical significance in the incidence of anausea and vomiting among 4 groups（P＞0.05）. CONCLUSIONS ：Parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with PICA can effectively relieve the pain of patients after gynecological laparoscopic surgery and reduce the levels of serum related factor ，and lornoxicam has the most obvious effect.

Objective:To explore the effect and involved mechanism of naringenin on acute kidney injury (AKI) induced by ischemia-reperfusion (IR).Methods:The IR-AKI rat model was constructed using the classic bilateral renal pedicle clamping method, then renal function and pathological change were assessed, as well as inflammation-associated genes were detected by quantitative real-time PCR. The hub genes were selected through differential gene analysis and protein-protein interaction network analysis, and their transcription factors were predicted, which constructed a protein library together. The proteins binding to naringenin were selected by reverse molecular docking analysis and further their binding patterns were predicted to explore the mechanism of naringenin. Finally, the results of bioinformatics were verified by experimental methods.Results:Compared with the AKI group, the kidney pathology of the rats in the naringenin pretreatment group was significantly improved, and the renal tubular injury score was reduced ( P<0.01); meanwhile the serum creatinine level and the mRNA expression of the kidney injury molecule 1 (KIM-1) were significantly decreased (both P<0.05). Compared to sham group, IR-AKI increased the level of nuclear factor κB (NF-κB), tumor necrosis factor-α and interleukin-1β (all P<0.05), which reversed by naringenin indicated that naringenin inhibited inflammation in IR-AKI. Differential gene analysis was performed on the GSE98622 data set, and 359 differential genes were obtained. In reverse molecular docking, the proteins with smallest binding energy including NFKBIA, BCL3, NFKB2 and RELA were considered to be related to the preventive effect of naringenin, which were mainly enriched in NF-κB-related inflammation pathways. Domain functional analysis of NF-κB-related genes showed that naringenin could stably bind to its key domain. According to quantitative real-time PCR results, naringenin increased BCL3 level after AKI ( P<0.05), and further decreased the expression level of RELA and NFKB2 (both P<0.05). Conclusion:Naringenin protects IR-AKI by alleviating inflammation, and its mechanism is related to increasing BCL3 and thereby inhibiting the NF-κB pathway.
