Objective: To analyze the influencing factors for hospitalization costs among stroke patients with different subtypes, so as to provide the reference for reducing the economic burden of patients. Methods: Data of patients with hemorrhagic or ischemic stroke who were discharged from hospitals in Nanshan District, Shenzhen City from January 1, 2016 to December 31, 2021 were collected through Hospital Information System. Hospitalization costs were analyzed between hemorrhagic and ischemic stroke patients, and factors affecting hospitalization costs among stroke patients with different subtypes were identified using a structural equation model. Results: A total of 10 298 patients with stroke were recruited, including 2 820 patients with hemorrhagic stroke (27.38%) and 7 478 patients with ischemic stroke (72.62%). The patients with hemorrhagic stroke had a median duration of hospital stay of 19.00 (interquartile range, 18.00) d, and a median hospitalization cost of 26 759.48 (interquartile range, 51 000.87) Yuan. The patients with ischemic stroke had a median duration of hospital stay of 12.00 (interquartile range, 10.00) d, and a median hospitalization cost of 12 199.87 (interquartile range, 13 290.20) Yuan. Structural equation model analysis showed that department of hospitalization, discharge status, ways of leaving hospital, surgery and hypertension had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among hemorrhagic stroke patients, and duration of hospital stay had the highest total effect (0.684), followed by surgery (0.632). Employment status, admission route, department of hospitalization, ways of leaving hospital, payment mode, surgery and dyslipidemia had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among ischemic stroke patients, and duration of hospital stay (0.746), surgery (0.424) and department of hospitalization (0.151) ranked the top three in total effects. Conclusion The hospitalization cost is relatively high among stroke patients in Nanshan District, and duration of hospital stay and surgery have great influence on hospitalization costs among stroke patients with different subtypes.

OBJECTIVE: To explore the relationship between serum lipoprotein-associated phospholipase A2 (Lp-PLA2) level and the risk of acute ischemic stroke (AIS) recurrence in hypertensive patients. METHODS: This retrospective case-control study was conducted among 211 hypertensive patients with AIS treated in Foshan First People's Hospital, including 35 patients with recurrence of AIS during the 1-year follow-up as confirmed by head CT/MR. In the overall patients, 60 had grade 1 hypertension (including 5 recurrent cases), 76 had grade 2 hypertension (with 11 recurrent cases), and 75 had grade 3 hypertension (with 19 recurrent cases). Univariate analysis, multivariate logistic regression analysis, trend analysis, and smooth curve fitting analysis were performed to explore the correlation between serum Lp-PLA2 level within 24 h after admission and the risk of AIS recurrence. The predictive efficacy of serum Lp-PLA2 level for AIS recurrence in different hypertension grades was evaluated using ROC curve analysis. RESULTS: Serum Lp-PLA2 level, age, NIHSS score at admission, mRS scores at 7 days, homocysteine level and smoking status differed significantly between patients with and without AIS recurrence (P < 0.05). After adjustment for confounding factors, multivariate regression analysis showed that the highest tertile of Lp-PLA2 level was associated with a 4.13-fold increase of AIS recurrence risk compared with the lowest tertile (OR=5.13, 95% CI: 1.35-19.40), and each 1 ng/mL increase of Lp-PLA2 level was associated with a 1% increase of AIS recurrence risk (OR= 1.01, 95% CI: 1.01-1.02). Serum Lp-PLA2 level was shown to positively correlate with AIS recurrence risk, and in patients with grade 3 hypertension, its areas under the ROC curve for predicting AIS recurrence was 0.869 with a specificity of 0.893 and a sensitivity of 0.737. CONCLUSION Serum Lp-PLA2 concentration is an independent risk factor and potentially an effective predictor for AIS recurrence in patients with grade 3 hypertension.

Objective: To investigate the trend in incidence of stroke in Nanshan District, Shenzhen City from 2010 to 2021, so as to provide the evidence for formulating the integrated strategy for stroke control. Methods: The data of stroke morbidity in Nanshan District from 2010 to 2021 were collected through Shenzhen Chronic Disease Prevention and Control Management System. The incidence of stroke was calculated, and standardized by the population of the Chinese Sixth National Census in 2010. The trends in stroke incidence were evaluated in Nanshan District from 2010 to 2021 using annual percent change (APC) and average annual percent change (AAPC), and gender-, age- and subtype-specific incidence of stroke was descriptively analyzed. Results: A total of 30 377 cases with stroke were reported in Nanshan District from 2010 to 2021, with a crude incidence rate of 190.45/105 and a standardized incidence rate of 405.65/105. The crude incidence rate of stroke appeared a tendency towards a rise in Nanshan District from 2010 to 2021 (APC=5.38%, t=4.678, P=0.001), and a higher crude incidence rate of stroke was seen among men than among women (227.57/105 vs. 148.40/105; χ2=1 309.580, P<0.001). The incidence of stroke appeared a tendency towards a rise with age (χ2trend =435.717, P<0.001), and there was a tendency towards a rise in stroke incidence among residents under 40 years of age (APC=2.89%, t=2.538, P=0.029). The crude incidence of ischemic stroke was 151.24/105, which was higher than that of hemorrhagic stroke (39.21/105) (χ2=10 521.000, P<0.001). Conclusions The incidence of stroke appeared a tendency towards a rise in Nanshan District from 2010 to 2021, with ischemic stroke as the predominant subtype of stroke. Males and middle-aged and elderly residents should be given a high priority for stroke prevention and treatment.

Aim To study the effects of lentinan(LNT)on the metabolism of dendritic cells(DCs)by metabonomics, and uncover the potential mechanism of its regulation of DC function. Methods DC2.4 cells were co-incubated with LNT for 24 h, and the activity of the cells was detected by thiazolyl blue tetrazolium bromide(MTT)assay. The contents of interleukin-6(IL-6), tumor necrosis factorα(TNF-α)and interleukin-12(IL-12)in supernatant were detected by enzyme-linked immunosorbent assay(ELISA). The metabolic general changes of DC2.4 cells were detected by Ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-QTOF/MS), and the differential metabolites were analyzed by multi-distance covariates and bioinformatics, partial least squares-discriminant analysis(PLS-DA). Finally, metabolic pathway analysis was performed by MetaboAnalyst 5.0. Results LNT did not significantly inhibit the activity of DC2.4 cells at the dose of 25100 mg·L-1. LNT(100 mg·L-1)could significantly stimulate the secretion of IL-6, TNF-α and IL-12 in DC2.4 cells. 20 differential metabolites were identified in DC2.4 cells after being stimulated by LNT(100 mg·L-1), which involved 25 metabolic pathways including urea cycle, arginine and proline metabolism. Conclusion The regulation of LNT on DC function involves a variety of amino acid metabolism.

Objective: To investigate the prevalence of current smoking and smoking cessation, and identify the influencing factors among hypertensive patients in Nanshan District, Shenzhen City, so as to provide insights into smoking control among hypertensive patients. Methods: The demographic features, life style, status of smoking and smoking cessation in hypertensive patients were collected from 69 community health centers in Nanshan District from 2017 to 2019. The gender- and age-specific prevalence of smoking and smoking cessation was estimated among hypertensive patients, and the factors affecting hypertensive patients' smoking and smoking cessation were identified using a multivariable logistic regression model. Results: Totally 4 385 patients with hypertension were enrolled, with a mean age of (58.41±11.19) years, and the participants included 2 265 men (51.65%) and 2 120 women (48.35%). There were 724 current smokers, and the prevalence of current smoking was 16.51%, with 29.71% prevalence in males and 2.41% in females. There were 424 hypertensive patients quitting smoking, and the prevalence of smoking cessation was 36.93%, with 38.20% prevalence in males. Multivariable logistic regression analysis identified male ( OR=12.885, 95%CI: 9.567-17.354 ) and drinking ( OR=2.567, 95%CI: 2.118-3.111 ) as facilitating factors for current smoking among hypertensive patients, and increasing age (OR=0.723, 95%CI: 0.642-0.815) and high exercise frequency (OR=0.881, 95%CI: 0.817-0.950) as barrier factors, while male ( OR=7.309, 95%CI: 3.304-16.165), increasing age ( OR=1.381, 95%CI: 1.120-1.703 ), unmarried ( OR=1.819, 95%CI: 1.329-2.490 ), divorced ( OR=7.837, 95%CI: 1.254-48.975 ), retired ( OR=1.545, 95%CI: 1.095-2.180 ), unemployed (OR=1.801, 95%CI: 1.057-3.066), and high exercise frequency ( OR=1.221, 95%CI: 1.096-1.360 ) were identified as facilitating factors for smoking cessation among hypertensive patients and widowed ( OR=0.285, 95%CI: 0.089-0.906 ), high educational level ( OR=0.766, 95%CI: 0.619-0.949 ), and drinking ( OR=0.488, 95%CI: 0.368-0.647 ) as barrier factors. Conclusions The prevalence of smoking is lower, and the prevalence of smoking cessation is higher among hypertensive patients than among general populations in Nanshan District. Young and middle-aged, employed, widowed men with a high educational level are key populations for tobacco control, and alcohol consumption control and intensified exercises are important measures to reduce the prevalence of smoking and improve the prevalence of smoking cessation.

Captopril can have nephrotoxic effects, which are largely attributed to accumulated renin and "escaped" angiotensin II (Ang II). Here we test whether angiotensin converting enzyme-1 (ACE1) inhibition damages kidneys via alteration of renal afferent arteriolar responses to Ang II and inflammatory signaling. C57Bl/6 mice were given vehicle or captopril (60 mg/kg per day) for four weeks. Hypertension was obtained by minipump supplying Ang II (400 ng/kg per min) during the second 2 weeks. We assessed kidney histology by periodic acid-Schiff (PAS) and Masson staining, glomerular filtration rate (GFR) by FITC-labeled inulin clearance, and responses to Ang II assessed in afferent arterioles in vitro. Moreover, arteriolar H₂O₂ and catalase, plasma renin were assayed by commercial kits, and mRNAs of renin receptor, transforming growth factor-β (TGF-β) and cyclooxygenase-2 (COX-2) in the renal cortex, mRNAs of angiotensin receptor-1 (AT₁R) and AT₂R in the preglomerular arterioles were detected by RT-qPCR. The results showed that, compared to vehicle, mice given captopril showed lowered blood pressure, reduced GFR, increased plasma renin, renal interstitial fibrosis and tubular epithelial vacuolar degeneration, increased expression of mRNAs of renal TGF-β and COX-2, decreased production of H₂O₂ and increased catalase activity in preglomerular arterioles and enhanced afferent arteriolar Ang II contractions. The latter were blunted by incubation with H₂O₂. The mRNAs of renal microvascular AT₁R and AT₂R remained unaffected by captopril. Ang II-infused mice showed increased blood pressure and reduced afferent arteriolar Ang II responses. Administration of captopril to the Ang II-infused mice normalized blood pressure, but not arteriolar Ang II responses. We conclude that inhibition of ACE1 enhances renal microvascular reactivity to Ang II and may enhance important inflammatory pathways.

Objective:To investigate the safety and therapeutic effect of Shakubatrivalsartan in the treatment of pediatric dilated cardiomyopathy.Methods:Clinical information, treatment and prognosis of 5 cases with dilated cardiomyopathy in the First Affiliated Hospital of Xinxiang Medical University from June 2018 to December 2020 were retrospectively analyzed, and relevant literatures were reviewed.Results:A total of 5 cases of children with dilated cardiomyopathy were analyzed, including 3 males and 2 females with age of 12-17 years.Their median left ventricular ejection fraction (LVEF), left ventricular end diastolic dimension (LVDd), N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were 37% (20%-41%), 61 mm (59-67 mm), and 13 250 ng/L (12 310-21 823 ng/L), respectively.The median conventional treatment time was 5 months (1-12 months), in which, the condition of heart failure gradually progressed, and the median LVEF, LVDd and NT-proBNP levels were reduced to 33% (19%-37%), 61 mm (60-74 mm), 13 144 ng/L (8 086-15 137 ng/L). After less than 3 months of follow-up following conventional treatment plus Shakubatrivalsartan, NT-proBNP level significantly decreased in 5 cases.Besides, 4 cases had improved cardiac function, and the other one′s improvement was not obvious.The blood pressure of 5 cases decreased at varying degrees after medication of Shakubatrivalsartan, which should be closely monitored during drug titration.No adverse reactions were reported.Conclusions:Shakubatrivalsartan for the treatment of pediatric dilated cardiomyopathy is safe and effective, which can alleviate or reverse the process of myocardial remodeling and improve cardiac ejection fraction, thus improving the prognosis.

Objective:To investigate the clinical characteristics of patients who develop chronic critical illness (CCI) after sepsis.Methods:The survival patients with sepsis admitted to the department of critical medicine of Baoan Central Hospital of Shenzhen for the first time from April 2019 to October 2020 were enrolled. According to clinical outcomes, patients were divided into CCI group [intensive care unit (ICU) stay ≥14 days, with persistent organ dysfunction] and rapid recovery (RAP) group. The baseline characteristic on admission and clinical outcomes of patients in the two groups were collected and compared. Blood samples were collected to measure serum interleukins (IL-6, IL-10) levels and peripheral blood lymphocyte count (LYM) count were obtained from all patients after admission. The differences of above indexes on the 1st, 7th and 14th day in ICU between the two groups were compared, the 180 day cumulative survival rate of the two groups was observed.Results:① Twenty-two septic patients developed CCI and 28 patients with RAP were included. There were no significant differences in gender and infection site between the two groups. The age, acute physiology and chronic health evaluationⅡ(APACHEⅡ), sequential organ failure assessment (SOFA), proportion of septic shock, mechanical ventilation time, length of ICU stay, total length of hospital stay and proportion of secondary infection of CCI patients were higher than those in RAP group [age (years old): 61.0±13.8 vs. 50.3±13.9, proportion of patients aged ≥ 65 years old: 54.5% (12/22) vs. 25.0% (7/28), APACHEⅡscore: 20.5±4.4 vs. 14.4±4.3, SOFA score: 10 (7, 12) vs. 5 (3, 8), septic shock ratio: 40.9% (9/22) vs. 17.9% (5/28), time of mechanical ventilation (days): 18.5 (12.0, 28.0) vs. 5.0 (3.0, 7.0), length of ICU stay (days): 26 (18, 46) vs. 8 (6, 12), total length of hospital stay (days): 31 (26, 51) vs. 14 (12, 17), secondary infection ratio: 72.7% (16/22) vs. 7.1% (2/28), all P < 0.05]. ② The IL-6 levels of CCI group were higher than that of RAP group at all time points (ng/L: 176.86±103.54 vs. 113.32±71.34 on the 1st day, 84.72±46.06 vs. 54.98±26.61 on the 7th day, 44.28±20.20 vs. 17.76±4.70 on the 14th day, all P < 0.05). On the 1st and 7th day of admission, there were no significant differences in IL-10 and LYM levels between the two groups. On the 14th day of admission, IL-10 levels in CCI group were higher than that in RAP group (ng/L: 15.09±3.61 vs. 8.92±1.98, P < 0.05), while LYM was relatively lower [×10 9/L: 0.62 (0.43, 1.02) vs. 1.17 (0.93, 1.71), P < 0.05]. ③ The Log-Rank test results of Kaplan-Meier survival curve showed that the 180-day cumulative survival rate of CCI group was significantly lower than that of RAP group (63.6% vs. 96.4%, Log-Rank:χ 2 = 9.024, P = 0.007). Conclusions:Septic patients with advanced age, high APAHCEⅡscore and high SOFA score are prone to secondary CCI, resulting in long hospital stay, high secondary infection rate and poor prognosis. The occurrence of CCI may be related to the continuous expression of proinflammatory mediators and subsequent immunosuppression.

OBJECTIVE: To explore the clinical effects of anterior cervical discectomy with fusion (ACDF) and anterior cervical corpectomy with fusion (ACCF) in treating adjacent two-segment cervical spondylotic myelopathy (CSM). METHODS: The clinical data of 37 patients with adjacent two segment CSM treated from January 2016 to December 2017 were retrospectively analyzed, including 15 males and 22 females, aged from 43 to 69 years old with an average of 54.6 years. The patients were divided into ACDF group (group A, =17) and ACCF group (group B, =20) according to the different surgery. The operation time and intraoperative blood loss were recorded;the Cobb angle and cervical curvature in the cervical fusion segments before surgery and 1, 12 months after surgery were observed;Japanese Orthopaedic Association (JOA) score was used to evaluate the surgical efficacy, and the postoperative complications were analyzed. RESULTS: All patients were followed up for 12 to 24 months with an average of 18.5 months. Operation time and intraoperative blood loss in group A were (106.3±22.6) min, (52.2±26.4) ml, respectively, while were (115.6±16.8) min, ( 61.7±20.7) ml in group B. There was no statistically significant in operation time between two groups(>0.05);intraoperative blood loss in group B was larger than group A(<0.05). The preoperative and postoperative 1 and 12 months, cervical curvature and Cobb angle of cervical fusion segment in group A were (11.28±1.40)°, (17.56±1.90)°, (16.64±1.80)° and (4.93±4.20) °, (9.44±2.60)°, (9.25±2.80)°, respectively, and in group B were (10.59± 1.20)°, (16.26±2.10)°, (15.76±2.50)° and (4.75±3.90)°, (7.98±2.10)°, (7.79±3.00)°. The cervical curvature and Cobb angle in all cervical fusion segments at 1, 12 months after surgery were obviously improved, and group A recovered more significantly than group B (<0.05). The JOA scores in group A were 9.46±1.70, 11.56±1.40, 14.86±1.20 before operation and 1 and 12 months after operation, and group B were 9.11±1.50, 11.40±1.30, 15.12±1.60, respectively. The postoperative JOA scores of the two groups were significantly improved (<0.05), and there was no statistically significant difference between two groups at the same time (>0.05). At the final follow up, in group A, dysphagia occurred in 2 cases, cage displacement in 1 case, and no titanium plate screw loose was found;and in group B, dysphagia occurred in 4 cases, titanium mesh collapse in 2 cases, titanium plate screw loose in 1 case. CONCLUSION Two types of anterior cervical decompression and fusion for the treatment of two segment cervical spondylotic myelopathy can effectively decompress and improve the Cobb angle and cervical curvature of the affected vertebra. The ACDF surgical procedure can directly removethe compressive thing at intervertebral level, which will lead to little vertebral body damage and favorably recovered cervical curvature. The ACCF surgical procedure has a large operation space, which can easily remove the posterior vertebral osteophyte and the calcified posterior longitudinal ligament. Long-term follow-up shows that ACDF and ACCF have good surgical procedures, mature technology, and close efficacy.
