Objective To evaluate the clinical efficacy of Yangyin Yiqi mixture and western medicine in the treatment of oral lichen planus(OLP)and its effect on the levels of interferon -γ(IFN -γ)and interleukine -10 (IL -10)in serum and saliva.Methods Sixty patients with OLP were randomly divided into control group(n =30) and treatment group(n =30).The control group was treated with triamcinolone acetonide and lidocaine,local injec-tion.The treatment group was treated with Yangyin Yiqi mixture on the basis of the control group.The treatment lasted two months.After treatment,the clinical efficacy,objective indicators score,levels of IFN -γand IL -10 in serum and saliva,adverse reactions were compared between the two groups.Results The overall response rate of the treatment group (86.67%)was significantly higher than that of the control group (63.33%)(χ2 =11.64,P <0.01).After treatment,the two groups'objective index score significantly reduced(t =8.52,12.51,all P <0.01),and the treat-ment group's objective indicators rating was significantly lower than the control group (t =4.38,P <0.05).After treatment,the levels of IFN -γin serum and saliva were (25.39 ±1.29)pg/mL and (12.76 ±1.28)pg/mL,which were significantly increased in the treatment group (t =10.35,8.15,all P <0.01),so did the control group (P <0.05).And the levels of IL -10 in serum and saliva were (27.54 ±1.82)pg/mL and (9.92 ±0.86)pg/mL,and the levels were significantly decreased in the two groups after treatment (t =8.76,9.39,all P <0.01,t =4.65,4.94,all P <0.05).And levels of IFN -γin serum and saliva of the treatment group were significantly higher than those of the control group (t =4.68,4.32,all P <0.05),and levels of IL -10 in serum and saliva of the treatment group were significantly lower than those of the control group (t =5.41,5.25,all P <0.05).During treatment,there were no sig-nificant adverse reactions.Conclusion Yangyin Yiqi mixture combined with western medicine has definitive clinical efficacy in the treatment of OLP.It can significantly increase the level of IFN -γand reduce the level of IL -10 in serum and saliva in patients,so provide theory value for treatment of OLP.

Objective To investigate the safety,effectiveness and prognosis of percutaneous microwave ablation (MWA) combined with synchronous transarterial chemoembolization (TACE) to treat of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) with liver metastases (LMs).Methods This retrospective study included 19 cases of GEP-NENs with LMs patients who received percutaneous MWA combined with synchronous TACE treatment from 2013 to 2016.The mRECIST standard was selected to assess the curative effect.SPSS 21.0 software was applied in the statistical analysis of overall survival (OS),progression-free survival (PFS) and factors related to prognosis.Results All patients were capable of curative effect evaluation,including 1 case of complete remission (CR),3 cases of partial remission (PR),7 cases of progressive disease (PD) and 8 cases of stable disease (SD) respectively accounting for 5 ％,16 ％,37 ％,42 ％,which exhibited 21％ of response rate (RR) and 63％ disease control rate (DCR).In the present study,the median OS and median PFS was respectively 25 months and 34 months,and the one-year survival and three-year survival was respectively 95％ and 84％.Serum CA199,the WHO classification of LMs and the tumor burden of LMs were the major risk factors of prognosis through single factor analysis of survival,which showed that G3 of the WHO classification of LMs predicted a poor OS (P＜0.05) and tumor burden of LMs was negatively related to PFS (P＜0.05).It was obviously observed that serum CgA was decreased by the therapy of percutaneous MWA with synchronous TACEfor GEP-NENs (P＜0.05).Conclusions Percutaneous MWA combined with synchronous TACE is a safe and effective method to treat GEP-NENs with LMs.

Objective To investigate the effectiveness and safety in patients with largeartery occlusive acute cerebral infarction who received multi-interventional modes mainly with mechanical thrombectomy and its related factors affecting prognosis. Methods The clinical data of 56 patients with large artery occlusive acute cerebral infarction were analyzed retrospectively. The clinical characteristics (gender,age,and underlying diseases),timing of treatment (time from ictus to puncture,time from puncture to recanalization), multi-interventional mode therapies (intra-arterial thrombolysis,thrombectomy,balloon dilation,and stenting, etc. ),and distribution of offending vessels were observed. The modified Thrombolysis in Cerebral Ischemia Scale (mTICI)grade was used to evaluate revascularization. The National Institute of Health Stroke Scale (NIHSS)score was used to observe the neurological function at 24 h before and after procedures. The modified Rankin scale (mRS)was used to evaluate the prognosis at 3 months after procedure. The safety of the treatment was evaluated with operative complications (mainly symptomatic intracranial hemorrhage)and mortality. The patients were divided into either a good prognosis group (n = 34;mRS≤2)or a poor prognosis group (n =22;mRS≥3)according to the prognosis at 3 months after procedure. They were analyzed with univariate analysis. The factors influencing the prognosis were further analyzed with multivariate logistic regression analysis. Results (1)The recanalization rate in 56 patients was 78. 6%(n = 44),in which basilar artery was the highest,reaching 93. 8% (15 / 16),middle cerebral artery was 87. 0% (20 / 23). The NIHSS score at 24 hours was 10 ± 7,it was lower than 16 ± 6 on admission. There was significant difference (t =6. 401,P <0. 01). At 3 months,34 patients (60. 7%)had good prognosis,4 (7. 1%)died,and 8 (14. 3%) had symptomatic intracranial hemorrhage. (2)Multiple factor analysis showed that the high level of recanalization was a protective factor for good prognosis (OR,0. 465,95% CI 0. 267 -0. 809,P =0. 007). Diabetes was an independent risk factor for poor prognosis (OR,5. 535,95% CI 1. 101 -27. 835, P = 0. 038). Conclusion Acute large artery occlusive cerebral infarction treated with the intra-arterial multi-interventional modes may quickly and effectively restore intracranial blood flow. It has the characteris-tics of high recanalization rate and good prognosis,and the higher the level of recanalization,the better the prognosis. Diabetes is an independent risk factor for poor prognosis.

Objective To evulate the effection of HBV on controlled attenuation parameters(CAP)measurement of fatty liver using FibroScan(R).Methods Patients with only non alcohol fatty liverdisease (NAFLD),only chronic hepatitis B(CHB)and CHB combining with NAFLD (CHB + NAFLD) were complete the CAP measurement with FibroScan-502.Results 579 patients with CHB,624 patients with NAFLD and 124 patients with CHB + NAFLD were recruited.CAP values of CHB was 218.90 ±56.40 dB/m,significantly lower than that of NAFLD (290.85 ± 61.46 dB/m,P =0.00) and that of CHB + NAFLD (284.93 ±64.70 dB/m,P =0.00).It is no difference between CAP values of CHB + NAFLD and NAFLD (P =0.55).It is no difference between CAP values of high load of HBVDNA group and the low,high load of HBsAg group and the low,and HBeAg positive group and the negative (P =0.73,0.93,0.55).Conclusion HBV infection does not effect on CAP values of FibroScan(R).

Objective:To develop the Health Promotion Behavior Intention Questionnaire for enterostomy patients and test its reliability and validity.Method:Based on the theory of planned behavior, the first draft of the questionnaire was formed through literature review, group discussion, correspondence with Delphi experts and pre-test. The convenient sampling method was used to select 419 patients with enterostomy who visited Stoma Outpatient Department of the Affiliated Hospital of Qingdao University from December 2020 to June 2021 to conduct a questionnaire survey. Item analysis and reliability and validity tests were carried out on the questionnaires.Results:The Health Promotion Behavior Intention Questionnaire for enterostomy patients included 15 items. Exploratory factor analysis extracted four common factors, namely, attitude, subjective norm, perceived behavioral control and behavioral intention. The cumulative variance contribution rate was 83.166%. The content validity index of item level was 0.875-1.000 and the content validity index of questionnaire level was 0.983. The Cronbach's α coefficient of the total questionnaire was 0.921 and the retest reliability coefficient was 0.848.Conclusions:The Health Promotion Behavior Intention Questionnaire for enterostomy patients has good reliability and validity and it can be used as a tool to evaluate the health promotion behavior intention of patients with enterostomy.

Objective To evaluate the effect of contrast medium on the renal function in patients with cerebrovascular disease accompanied by diabetes mellitus after receiving neuro - interventional therapy. Methods The clinical data of a total of 108 patients with cerebrovascular disease complicated by diabetes mellitus type 2, who were treated with neuro - interventional therapy during the period from March 2013 to March 2016, were retrospectively analyzed. The contrast dose used in interventional procedures was less than 250ml in each patient. The preoperative and 24 h -postoperative serum creatinine (sCr), serum cystatin C (Cys C) levels were determined, and based on the modification of dietary renal disease (MDRD) equation and Larsson equation the estimated glomerular filtration rates (eGFR) were separately calculated. Results Compared with preoperative values, the 24 h - postoperative mean sCr and Cys C levels were increased significantly (P=0. 001, P=0. 015 respectively), while the average eGFR rates were remarkably decreased (P＜ 0. 000 1 by using MDRD equation, and P=0. 021 by using Larsson equation). No kidney damage that needed to be treated occurred in all patients. Conclusion The contrast dose used in neuro - interventional procedures can cause decline of renal function in patients with type 2 diabetes mellitus. The combined determination of sCr and Cys C levels is helpful for the detection of contrast - induced changes in renal function as early as possible. The use of conventional dose of contrast agent in neuro - interventional procedures is safe for patients with type 2 diabetes mellitus. (J Intervent Radiol, 2018, 27:277-280)

Objective:To compare the clinical characteristics and analyze the prognostic factors between human immunodeficiency virus (HIV)-infected patients and non-HIV-infected immunocompromised patients with pneumocystis pneumonia (PCP) complicated with acute respiratory failure (ARF) in intensive care unit (ICU).Methods:The clinical data of patients with PCP complicated with ARF admitted in ICU of The First Affiliated Hospital of Zhengzhou University and The Sixth People′s Hospital of Zhengzhou City between May 2018 and October 2020 were retrospectively reviewed. All subjects were divided into HIV-infected group and non-HIV-infected immunocompromised group. General characteristics and underlying diseases of patients in the two groups were analyzed. Laboratory parameters, treatment and outcomes between two groups were compared. Independent sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis, and univariate and multivariate logistic regression models were used to identify the risk factors for the clinical outcome. Results:A total of 129 PCP complicated with ARF patients were enrolled, including 75 HIV-infected patients and 54 non-HIV-infected immunocompromised patients. Only 10.7%(8/75) patients of HIV-infected group received anti-retroviral therapy (ART), but none of the patients in either groups had previously received trimethoprim-sulfamethoxazole (TMP-SMX) for PCP prophylaxis. Acute physiology and chronic health evaluation (APACHE) Ⅱ score of HIV-infected group was 18.7±6.0, which was higher than that in non-HIV-infected immunocompromised group (13.1±4.4) when admitted in ICU ( t=-5.45, P<0.001). Hypoproteinemia was common in both groups. Ninety-six percent (72/75) of HIV-infected patients had CD4 + T lymphocyte counts lower than 200/μL and 84.0%(63/75) of patients had CD4 + T lymphocyte counts even lower than 50/μL, while 5.74%(31/54) of patients in non-HIV-infected immunocompromised group had CD4 + T lymphocyte counts lower than 200/μL. The CD4 + /CD8 + T lymphocyte counts ratio was 0.05(0.02, 0.12) in HIV-infected group, which was lower than that in non-HIV-infected immunocompromised group (0.96(0.64, 1.44)), and the difference was statistically significant ( Z=-9.16, P<0.001). The length of ICU stay and hospital stay of non-HIV-infected immunocompromised patients were 10.0(7.0, 14.0) days and 18.0(11.8, 32.5) days, respectively, which were both longer than those in HIV-infected patients (7.0(4.0, 9.0) days and 13.0(7.0, 23.0) days, respectively), and the differences were both statistically significant ( Z=-3.58 and -2.73, respectively, both P<0.050). The hospital mortality of HIV-infected patients was 57.3%(43/75), which was significantly higher than that in non-HIV-infected immunocompromised patients (38.9%, 21/54) ( χ2=4.27, P=0.039). Multivariable logistic regression identified that lactic dehydrogenase (LDH), C-reactive protein (CRP) and APACHE Ⅱ score were the risk factors for the clinical outcome of HIV-infected patients (odds ratio ( OR)= 1.006, 1.015 and 1.736, respectively, all P<0.050). The partial pressure of oxygen in arterial blood/fractional concentration of inspiratory oxygen (PaO 2/FiO 2), LDH and CD4 + T lymphocyte counts were the risk factors for the clinical outcome of non-HIV infected immunocompromised patients ( OR=0.970, 1.008 and 0.989, respectively, all P<0.050). Conclusions:PCP patients with ARF are critically ill with high mortality rate. LDH, CRP and APACHEⅡscore are predictors for prognosis of HIV-infected patients with PCP, while PaO 2/FiO 2, LDH and CD4 + T lymphocyte counts are predictors for prognosis of non-HIV infected immunocompromised patients with PCP.

Objective To investigate the association between cardiovascular autonomic function and voiding symptoms in Parkinson disease(PD)patients.Methods We reviewed PD patients from the Department of Neurology of Guangdong Provincial People's Hospital(Guangdong Academy of Medical Sciences)between November 2020 and July 2023.Patients with PD were diagnosed by movement disorder specialists and received motor symptoms assessment based on Movement Disorders Society-Unified Parkinson's Disease Rating Scale part Ⅲ(MDS-UPDRS Ⅲ).We included those patients who underwent 24-hour ambulatory blood pressure monitoring(ABPM),ultrasound measured post void residual(PVR)and uroflowmetry.Subjects were divided into two groups:PD patients with nocturnal hypertension(PD-NH)group and PD patients without nocturnal hypertension(PD-nNH)group,according to the average nocturnal blood pressure.General clinical features,clinical assessments and urinary evaluations were compared between the two groups.We calculated average real variability(ARV)and examined its correlation factors using generalized linear models.Results Among the total of 87 PD patients,46(52.87% )were found to have nocturnal hypertension(NH).The PD-NH group exhibited more PVR[1.00(0.00,21.25)mL]compared to the PD-nNH group[0.00(0.00,5.50)mL](P<0.05).Additionally,generalized linear model analysis which scale response is Gamma with log link showed in PD patients,ARV of 24-hour diastolic blood pressure was correlated with PVR(OR=1.003,95% CI:1.001-1.005,P=0.008)and sex(male,OR=1.234,95% CI:1.050-1.451,P=0.011).Conclusion Our study demonstrates the association between cardiovascular autonomic function and voiding symptoms in PD.

Objective:To compare the efficacy of the combination of abidol, lopinavir/ritonavir plus recombinant interferon α-2b (rIFNα-2b) and the combination of lopinavir/ritonavir plus rIFNα-2b for patients with COVID-19 in Zhejiang province.Methods:A multicenter prospective study was carried out to compare the efficacy of triple combination antiviral therapy and dual combination antiviral therapy in 15 medical institutions of Zhejiang province during January 22 to February 16, 2020. All patients were treated with rIFNα-2b (5 million U, 2 times/d) aerosol inhalation, in addition 196 patients were treated with abidol (200 mg, 3 times/d) + lopinavir/ritonavir (2 tablets, 1 time/12 h) (triple combination group) and 41 patients were treated with lopinavir/ritonavir (2 tablets, 1 time/12 h) (dual combination group). The patients who received triple combination antiviral therapy were further divided into three subgroups: <48 h, 3-5 d and >5 d according the time from the symptom onset to medication starting. The therapeutic efficacy was compared between triple combination group and dual combination group, and compared among 3 subgroups of patients receiving triple combination antiviral therapy. SPSS 17.0 software was used to analyze the data.Results:The virus nucleic acid-negative conversion time in respiratory tract specimens was (12.2±4.7) d in the triple combination group, which was shorter than that in the dual combination group [(15.0±5.0) d] ( t=6.159, P<0.01). The length of hospital stay in the triple combination group [12.0 (9.0, 17.0) d] was also shorter than that in the dual combination group [15.0 (10.0, 18.0) d] ( H=2.073, P<0.05). Compared with the antiviral treatment which was started within after the symptom onset of in the triple combination group, the time from the symptom onset to the viral negative conversion was 13.0 (10.0, 17.0), 17.0 (13.0, 22.0) and 21.0 (18.0, 24.0) d in subgroups of 48 h, 3-5 d and >5 d, respectively ( Z=32.983, P<0.01), while the time from antiviral therapy to viral negative conversion was (11.8±3.9), (13.5±5.1) and (11.2±4.3) d, respectively( Z=6.722, P<0.05). Conclusions:The triple combination antiviral therapy of abidol, lopinavir/litonavir and rIFNα-2b shows shorter viral shedding time and shorter hospitalization time, compared with the dual combination antiviral therapy; and the earlier starting triple combination antiviral therapy will result in better antiviral efficacy.

Background Protein tyrosine phosphatase non-receptor type II (PTPN2) is essential for the regulation of inflammation and immunity, but the specific mechanism of action of Ptpn2 in silicosis is unknown. Objective To investigate the regulatory role of overexpression of Ptpn2 in SiO₂-mediated inflammatory response in alveolar type II epithelial cells based on transcriptome sequencing. Methods This study was an in vitro study. A negative control group (vector transferred) and an overexpression of Ptpn2 group of mouse lung epithelial cell line MLE-12 cells were firstly constructed. Transcriptome sequencing was performed to detect differentially expressed genes (DEGs), differentially expressed mRNAs, and differentially expressed ncRNAs in the two groups of MLE-12 cells, and then the DEGs were analyzed by the Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG). Constructed MLE-12 cells and A549 cells were stimulated using SiO₂ suspension, and divided into a negative control group (vector transferred), an overexpression of Ptpn2 group, a negative control + SiO₂ group, and an overexpression of Ptpn2 + SiO₂ group, respectively. Protein expressions of tumor necrosis factor-α (TNF-α) and interleukin (IL)-17A, IL-2, IL-1β were detected by Western blot. Positive TNF-α expression was detected by immunofluorescence staining. Results The results of Western blot showed that the protein expression level of PTPN2 was up-regulated in the overexpressed Ptpn2 group compared with the negative control group (P < 0.05). The volcano plot and clustering heat map showed that there were 1122 DEGs, 3681 differentially expressed mRNAs, and 474 differentially expressed ncRNAs in the overexpressed Ptpn2 group compared with the negative control group. The results of GO enrichment showed that, in terms of the biological process, the DEGs were mainly related to the regulation of metal ion transport, extracellular matrix organization, and extracellular structural organization; in terms of cellular composition, the DEGs were mainly related to collagen-containing extracellular matrix, receptor complexes, and basement membranes; in terms of molecular function, the DEGs were mainly related to the extracellular matrix structural constituents, glycosaminoglycan binding, and semaphorin receptor binding. The results of KEGG enrichment showed that the DEGs were closely related to cytokin-cytokine receptor interaction, IL-17 signaling pathway, TNF signaling pathway, and chemokine signaling pathway. In MLE-12 and A549 cells, the results of Western blot showed that the protein expression levels of TNF-α , IL-17A, IL-2, and IL-1β were up-regulated in the negative control + SiO₂ group compared with the negative control group (P < 0.05), and the protein expression levels of TNF-α, IL-17A, IL-2, and IL-1β were down-regulated in the overexpression of Ptpn2 + SiO₂ group compared with the negative control + SiO₂ group (P < 0.05). The immunofluorescence staining showed that the expression of TNF-α was increased in the negative control + SiO₂ group compared with the negative control group, and decreased in the overexpression of Ptpn2 + SiO₂ group compared with the negative control + SiO₂ group. Conclusion Overexpression of Ptpn2 inhibits SiO₂-mediated inflammatory response in MLE-12 cells and A549 cells.
