ABSTRACT

OBJECTIVE@#To compare the clinical efficacy of combined application of glycine powder air-polishing and mechanical submucosal debridement in non-surgical treatment of peri-implant diseases.@*METHODS@#A randomized controlled clinical study was carried out on patients diagnosed with peri-implant diseases in the Department of Periodontology, Peking University School and Hospital of Stomatology, between May of 2020 and June of 2021.Twenty-eight patients with totally sixty-two implants were enrolled.The patients were randomly divided into the test group and control group. The patients in the test group (13 subjects/32 implants) received mechanical submucosal debridement using titanium curettes combined with application of glycine powder air-polishing, while the control group (15 subjects/30 implants) received mechanical submucosal debridement using titanium only. Clinical parameters, such as plaque index (PLI), pocket probing depth (PPD), bleeding index (BI) and the percentage of suppuration on probing on implants' level (SoP%) were measured at baseline and 8 weeks after non-surgical intervention. Changes and group differences of clinical parameters of the implants before and 8 weeks after non-surgical intervention were compared.@*RESULTS@#Mean PLI, PPD, BI of both the test group and control group significantly reduced 8 weeks after non-surgical intervention (P < 0.05). Compared with the control group, the test group achieved lower BI (2.7±0.8 vs. 2.2±0.7, P < 0.05), more reduction of BI (0.6±0.7 vs. 1.1±0.6, P < 0.01) and more reduction of SoP% (21.9% vs. 10%, P < 0.05) after non-surgical intervention. Both the control and test groups exhibited comparable PLI and PPD reductions (P>0.05). For the implants diagnosed with peri-implant mucositis, the test group revealed more signi-ficant reduction in BI and SoP% than the control group (1.0±0.7 vs. 0.4±0.7, P=0.02; 6.3% vs. 0, P=0.012). There was no significant difference existing in PLI and PD improvement between the control group and test group (P>0.05). For the implants diagnosed with peri-implantitis, there was no significant difference existing in PLI, PPD, BI and SoP% improvement values between the test and control groups (P>0.05). No complications or discomforts were reported during the study.@*CONCLUSION@#Both treatment procedures could relieve the inflammation of peri-implant soft tissue. Non-surgical mechanical submucosal debridement combined application of glycine powder air-polishing is associated with significant reduction of soft tissue bleeding and suppuration on probing especially in the implants diagnosed with peri-implant mucositis.

ABSTRACT

Objective: To evaluate the real-world efficacy and safety of sofosbuvir and velpatasvir (SOF/VEL) tablets in the treatment of Chinese patients with chronic HCV infection. Methods: An open-label, single-center, prospective clinical study was conducted in a county in northern China. A total of 299 cases were enrolled. Of these, 161 cases with chronic hepatitis C and 73 cases with compensated cirrhosis received SOF/VEL for 12 weeks. 65 cases with decompensated cirrhosis received SOF/VEL combined with ribavirin for 12 weeks (22 cases) or SOF/VEL for 24 weeks (43 cases). Virological indicators, liver and renal function indexes, and liver stiffness measurement were detected at baseline, the fourth week of treatment, the end of treatment, and the 12-weeks of follow-up. Adverse reactions and laboratory abnormalities were observed during the course of treatment . The primary endpoint was undetectable rate of HCV RNA (SVR12) at 12 weeks of follow-up with the use of modified intention-to-treat (mITT) approach. Measurement data between two groups were compared using t-test. One Way ANOVA was used for comparison between multiple groups. Enumeration data were analyzed by chi-square test or Fisher's exact test. Results: 291 cases had completed treatment. HCV RNA was undetectable after 12 weeks of follow-up, and the SVR12 rate was 97.3% (95% confidence interval: 95.4%-99.3%). Among them, 97.4% of genotype 1b, 96.4% of genotype 2a, and 100% of those with undetected genotype achieved SVR12. The SVR12 rates in patients with chronic hepatitis C, compensated and decompensated liver cirrhosis were 98.1%, 98.6% and 93.8%, respectively. An improvement in alanine aminotransferase, aspartate aminotransferase and other liver biochemical indicators accompanied with virological clearance and reduced liver stiffness measurement was observed in patients with compensated cirrhosis, with statistically significant difference. There was no significant abnormality in renal function before and after treatment. The most common adverse reactions were fatigue, headache, epigastric discomfort and mild diarrhea. The overall adverse reactions were mild. One patient died of decompensated liver cirrhosis combined with massive upper gastrointestinal bleeding, which was unrelated to antiviral treatment. Four patients discontinued treatment prematurely due to adverse events. Relapse was occurred in four cases, and drug-resistance related mutations were detected in three cases. Conclusion: Sofosbuvir and velpatasvir tablets in Chinese HCV-infected patients with different genotypes, different clinical stages or previously treated with pegylated interferon combined with ribavirin resulted in higher SVR12, indicating that the treatment safety profile is good.

ABSTRACT

Objective:To explore the effects of long non-coding RNA (lncRNA) FAM224A on the proliferation and migration of ovarian cancer cells by regulating the expression of miRNA-590-3p (miR-590-3p).Methods:Human ovarian cancer cell lines OC3, SKOV-3, HO-8910, A2780 and human normal ovarian epithelial cell line IOSE80 were selected, and the relative expression of FAM224A in each cell line was detected by real-time quantitative polymerase chain reaction (qRT-PCR). The cell line with the lowest relative expression level of FAM224A was screened for follow-up experiment. The cells were divided into FAM224A group (transfected with FAM224A mimic gene) and control group (transfected with control mimic gene). CCK-8 method and cell scratch test were used to detect the cell proliferation and migration ability of the two groups. The bioinformatics website LncBase v.2 predicted that the target gene that FAM224A might complementarily bind to was miR-590-3p. qRT-PCR was used to detect the relative expression levels of miR-590-3p and forkhead box protein A2 (FOXA2) mRNA, and the expressions of related proteins were detected by Western blot.Results:The relative expression levels of FAM224A in ovarian cancer cell lines OC3, SKOV-3, HO-8910, A2780 and normal ovarian epithelial cell line IOSE80 were 0.23±0.04, 0.65±0.05, 0.45±0.03, 0.63±0.08 and 1.02±0.11, respectively, and the difference was statistically significant ( F = 14.78, P < 0.01), and the cell line with the lowest relative expression level of FAM224A was OC3. The results of CCK-8 method showed that the proliferation ability of OC3 cells in the FAM224A group was lower than that in the control group on the 2nd, 3rd, 4th and 5th day of culture (all P < 0.05). The scratch healing rates of OC3 cells in the FAM224A group and the control group were (18.6±2.3)% and (71.7±7.2)%, respectively, and the difference was statistically significant ( t = 6.99, P < 0.01). The relative expression levels of FAM224A in OC3 cells in the FAM224A group and the control group was 12.36±1.45 and 1.14±0.24, respectively ( t = 13.08, P < 0.01); the relative expression levels of miR-590-3p were 0.19±0.06 and 1.04±0.20, respectively ( t = 4.01, P < 0.01); the relative expression levels of FOXA2 mRNA were 6.37±1.37 and 1.05±0.08, respectively ( t = 3.86, P < 0.01). Compared with the control group, the expression of FOXA2 protein in OC3 cells in the FAM224A group was increased, the expressions of cell proliferation protein cyclin-dependent kinase 2 (CDK2) and cyclin D3 were decreased, and the expression of cell migration protein Snail was decreased. Conclusions:FAM224A is low expressed in ovarian cancer cell lines. FAM224A reduces the proliferation and migration ability of ovarian cancer OC3 cells by inhibiting the expression of miR-590-3p.

ABSTRACT

Objective:To explore the risk factors of abdominal hemorrhage (AH) in patients with severe acute pancreatitis (SAP) and its impact on outcome.Methods:The clinical data of 231 SAP patients admitted to Diagnosis and Treatment Center for SAP of Guizhou Province from January 1, 2015 to December 31, 2019 were retrospectively analyzed. These patients were divided into AH group and non-AH group. The general information, etiology, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score, organ failure, complications, interventions, bleeding time, bleeding site and outcome were compared between the two groups. Binary multivariate Logistic regression analysis was used to explore the risk factors of AH in SAP patients and whether the time and location of AH were risk factors affecting the outcome.Results:A total of 231 patients were enrolled in the analysis, including 198 patients without AH and 33 with AH (14.3%). There was no significant difference in gender, age or etiology between the two groups. The scores of APACHE Ⅱ and SOFA in AH group were significantly higher than those in non-AH group [APACHE Ⅱ score: 18 (12, 24) vs. 13 (9, 19), SOFA score: 9 (5, 15) vs. 5 (4, 11), both P < 0.01]. The incidences of acute kidney injury (AKI), gastrointestinal dysfunction, coagulation disorders, necrotic infection, pseudocyst and gastrointestinal fistula in AH group were significantly higher than those in non-AH group (66.7% vs. 47.0%, 36.4% vs. 7.1%, 18.2% vs. 6.6%, 66.7% vs. 9.1%, 66.7% vs. 34.3%, 9.1% vs. 1.5%, all P < 0.05). The proportions of requiring mechanical ventilation (MV) and surgical intervention in AH group were significantly higher than those in non-AH group (69.7% vs. 43.4, 48.5% vs. 14.6%, both P < 0.01). The length of intensive care unit (ICU) stay and hospital stay in AH group were significantly longer than those in non-AH group [length of ICU stay (days): 13 (8, 19) vs. 7 (3, 16), length of hospital stay: 24 (13, 40) vs. 17 (12, 24), both P < 0.01], and the hospital mortality was significantly higher (60.6% vs. 9.6%, P < 0.01). Multivariate Logistic regression analysis showed that APACHE Ⅱ score [odds ratio ( OR) = 1.157, 95% confidence interval (95% CI) was 1.030-1.299, P = 0.014], infectious necrosis ( OR = 12.211, 95% CI was 4.063-36.697, P < 0.01), pseudocyst ( OR = 3.568, 95% CI was 1.238-10.283, P = 0.019) and requiring MV ( OR = 0.089, 95% CI was 1.354-6.625, P = 0.007) were the risk factors of AH in SAP patients. In 33 AH patients, there was no significant difference in hospital mortality between early hemorrhage (occurred within 2 weeks of onset) and late hemorrhage (occurred 2 weeks after onset) groups [66.7% (8/12) vs. 57.1% (12/21), P > 0.05]. All 4 patients in the unspecified bleeding site group died during hospitalization; half or more patients died in the pseudocyst/abscess bleeding (14 cases), mesenteric/intestinal bleeding (13 cases) and gastric variceal bleeding (2 cases) groups (7 cases, 8 cases and 1 case respectively), and there were significant differences among the groups ( P < 0.05). Multivariate Logistic regression analysis showed that neither bleeding time ( OR = 0.989, 95% CI was 0.951-1.028, P = 0.574) nor bleeding site ( OR = 2.009, 95% CI was 0.822-4.907, P = 0.126) was the risk factor of death in patients with SAP combined with AH. Conclusions:Both early and late bleeding significantly increased the length of hospital stay and mortality of SAP patients. APACHE Ⅱ score, infectious necrosis and pseudocyst were the risk factors of AH in SAP patients. Neither bleeding time nor bleeding site was the risk factors of death in patients with SAP combined with AH. However, it still needed to be confirmed by a large sample clinical study.

ABSTRACT

Objective:To investigate the clinical characteristics and treatment of patients with refractory spasm tetanus.Methods:Tetanus patients admitted to the Affiliated Hospital of Zunyi Medical University from January 2011 to April 2021 were collected and divided into the refractory spasm group and general group according to whether they were refractory spasm. The general demographic characteristics, clinical characteristics, treatment and prognosis of the two groups were compared. The treatment and risk predictors of patients with refractory spasm tetanus were explored.Results:Among the 59 tetanus patients, 35 patients (59.32%) were in the refractory spasm group and 24 patients (40.68%) were in the general group. There were no significant differences in sex, age, latency and trauma site between the two groups ( P>0.05). All patients with refractory spasmodic tetanus were treated with mechanical ventilation, the length of hospital stay was significantly prolonged, and the rate of pulmonary infection was significantly increased ( P<0.05). The incidence of multiple sites muscular rigidity (spasm/limb stiffness, neck stiffness, and angular pedicle tension) in patients with refractory spasmodic on the first day of admission was higher than that in the general group ( P<0.05). The patients' initial symptoms (within 24 h after admission) were muscle spasm/limb stiffness + neck stiffness + angular pedicle inversion, which had the highest specificity for predicting the occurrence of refractory spasm. The proportion of Ablett grade Ⅳ in patients with refractory spasm was higher than that in the general group, and the difference was statistically significant ( P<0.05). The 48.75% patients with refractory spasm tetanus were treated with more than 3 sedatives combined with muscle relaxants, and the duration of sedative use was significantly prolonged ( P<0.05). Conclusions:The mechanical ventilation time and hospitalization time in tetanus patients with refractory spasm are significantly prolonged, and the incidence of pulmonary infection is significantly increased, which requires the combined application of a large number of sedative and muscle relaxants for a long time, and the incidence of refractory spasm is higher in patients with multi-site muscular rigidity at the early stage of the disease.

ABSTRACT

ObjectiveWe aimed to investigate the efficacy and mechanism of Yishen Shengjing Prescription (YSP) in the treatment of oligoasthenospermia in rats. MethodThe oligoasthenospermia rat model was established by injection with cyclophosphamide (35 mg·kg-1·d-1) for 5 consecutive days. Rats were randomly assigned into control group (without treating with cyclophosphamide), model group, low- (YSP-L), medium- (YSP-M), and high- (YSP-H) dose (2.91, 5.83, and 11.66 g·kg-1, respectively) groups, Wuzi Yanzongwan (WYW, 1.03 g·kg-1) group, and L-carnitine (0.17 g·kg-1) group, with 8 rats in each group. After 28 days of drug intervention, the body weight, testicular weight, and testicular index of rats were recorded. The sperm quality in epididymis was detected by computer-assisted sperm analysis (CASA) system. Hematoxylin-eosin (HE) staining was employed for observation of testicular tissue morphology. The levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in testicular tissue were detected by colorimetry. The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T) in serum were determined by enzyme-linked immunosorbent assay(ELISA). TdT-mediated dUTP nick-end labeling (TUNEL) was employed to detect the apoptosis of testicular cells. The protein levels of B cell lymphoma-2(Bcl-2), Bax, and cleaved Caspase-3 in testicular tissue were detected by Western blot. ResultCompared with the control group, the model group showed decreased body weight, testicular weight and index, sperm concentration and motility (P<0.01) and increased testicular pathological score (P<0.01). Compared with the model group, the YSP-M, YSP-H, WYW, and L-carnitine groups showed increased body weight, testicular weight, testicular index, sperm concentration and motility and decreased testicular pathological score. After modeling, the SOD level decreased (P<0.01) while the MDA content increased (P<0.01) in the testicular tissue. YSP-H, WYW, and L-carnitine reversed the SOD and MDA level changes caused by modeling. Compared with the control group, the model group exhibited declined T level (P<0.01) and increased FSH and LH levels (P<0.01). Compared with the model group, YSP, WYW, and L-carnitine increased the T level (P<0.01) and decreased the LH level (P<0.05, P<0.01). The apoptosis rate of spermatogenic cells in the model group was higher than that in the control group (P<0.01), whereas YSP-M, WYW, and L-carnitine reversed such changes (P<0.01). The model group rats showed decreased expression of Bcl-2(P<0.05) and increased expression of Bax and cleaved Caspase-3 (P<0.05, P<0.01). Compared the model group, YSP-M, YSP-H, WYW, and L-carnitine up-regulated the Bcl-2 expression and down-regulated the cleaved Caspase-3 expression (P<0.05, P<0.01). ConclusionYSP improved the sperm quality of oligoasthenospermia model rats by regulating the antioxidant system and sex hormone levels and inhibiting the apoptosis of spermatogenic cells.

ABSTRACT

The present study analyzed the correlations between curcumin(Cur), nuclear factor E2 related factor 2(NRF2)-dimethylarginine dimethylaminohydrolase(DDAH)-asymmetric dimethylarginine(ADMA)-nitric oxide(NO) pathway, and endothelial-mesenchymal transition(EndMT) based on SD rats with cardiac fibrosis, and explored the effect and mechanism of Cur in resisting cardiac fibrosis to provide an in-depth theoretical basis for its clinical application in the treatment of heart failure. The cardiac fibrosis model was induced by subcutaneous injection of isoprenaline(Iso) in rats. Thirty-two rats were randomly divided into a control group, a model group, a low-dose Cur group(100 mg·kg~(-1)·d~(-1)), and a high-dose Cur group(200 mg·kg~(-1)·d~(-1)), with eight in each group. After 21 days of treatment, cardiac function was detected by echocardiography, degree of cardiac fibrosis by Masson staining, expression of CD31 and α-SMA by pathological staining, expression of VE-cadherin, vimentin, NRF2, and DDAH by Western blot, and ADMA level by HPLC. Compared with the model group, the Cur groups showed alleviated cardiac fibrosis, accompanied by increased CD31 and VE-cadherin expression and decreased α-SMA and vimentin expression, indicating relieved EndMT. Additionally, DDAH and NRF2 levels were elevated and ADMA and NO expression declined. Cur improves cardiac fibrosis by inhibiting EndMT presumedly through the NRF2-DDAH-ADMA-NO pathway.

ABSTRACT

Purpose@#To identify more accurate predictors of upper urinary tract dilatation (UUTD) in neurogenic bladder (NB) children, we studied the relationship among urodynamic parameters at different bladder filling stages, detrusor leak point pressure (DLPP) and UUTD. @*Methods@#A total of 158 children (3–16 years) with NB were included and then divided into 2 groups according to whether their NB diagnosis was complicated with UUTD: the UUTD group (39 patients) and those without UUTD group (control group, 119 patients). The bladder filling phase was divided into 3 equal parts: the early, middle, and end filling stages. The bladder compliance (BC) and detrusor pressure (△Pdet) at each phase and DLPP at the end filling stage were recorded. @*Results@#A BC8 cm H2O in the early stage, 20 cm H2O in the middle stage and 25 cm H2O in the end stage are more sensitive than △Pdet >40 cm H2O in the end stage (82%, 85%, 85%, vs. 49%). A DLPP cutoff value of 20 cm H2O showed higher sensitivity for predicting UUTD than 40 cm H2O. @*Conclusions@#Low BC and a high △Pdet in the middle and end filling stages are more accurate factors than classic indicators for predicting UUTD. In addition, a DLPP value of >20 cm H2O in the end bladder filling stage shows high sensitivity.

ABSTRACT

Objective We aimed to assess the association between urinary bisphenol A(BPA)concentrations and gestational age in pregnant women. Methods A total of 248 pregnant women were recruited from a maternal and child care hospital in Shanghai. A questionnaire survey was completed to collect socio-demographic information and spot urine samples were collected during pregnancy. Gas chromatography-tandem mass spectrometry(GC-MS/MS)was used to measure BPA concentrations in urine samples. Linear relationship between urinary BPA level and gestational age was assessed by using generalized additive models. Multivariate regression model was used to evaluate associations of prenatal BPA exposure with gestational age. Results BPA was detected in all the urine samples. Median value and geometric mean of urinary BPA levels were 0.85 μg/L and 1.21 μg/L, respectively. Linear relationship between urinary BPA concentration and gestational weeks was confirmed(non-linear P > 0.05). Positive association between urinary BPA level and gestational age was indicated(regression coefficient, β = 0.19;95%CI:0.04-0.35;P = 0.016). However, it was only observed in girls, stratified by sex of newborns(β = 0.18;95%CI:0.03-0.34;P = 0.020). After stratification by trimester, no significant association was found in the second or the third trimesters. Conclusion Pregnant women are extensively exposed to BPA. Urinary BPA exposure during pregnancy may extend gestational age, especially in girls.

ABSTRACT

Purpose@#This study aimed to investigate the prevalence, risk factors, and effects of primary nocturnal enuresis (PNE) on physical and mental health in young adults in mainland China. @*Methods@#An anonymous questionnaire was used to collect information including the sociodemographic characteristics, history of PNE, family history, daytime voiding symptoms, Pittsburgh Sleep Quality Index (PSQI) scores, Self-Esteem Scale (SES), and Self-Rating Depression Scale (SDS). A total of 22,500 university students from 23 provinces and 368 cities in mainland China were included. @*Results@#In total, 21,082 questionnaires were collected, and 20,345 of them qualified for statistical analysis. The PNE prevalence was 1.17%, and the distribution of monosymptomatic nocturnal enuresis (MNE) and nonmonosymptomatic nocturnal enuresis (NMNE) was 66.1% and 33.9%, respectively. In total, 28% of respondents with PNE reported bedwetting daily, 31.6% between 1 and 7 times weekly, and 40.4% between 1 and 4 times monthly; 80% of PNE cases had no history of treatment. The prevalence of PNE in patients with a family history, frequency, urgency, urinary incontinence, and recurrent urinary tract infections was significantly higher than in those without these conditions (P<0.001). PNE was significantly correlated with the PSQI total score (sleep quality) (P=0.011). The SES score was lower and the SDS was higher (P<0.001) in the PNE group than in those without PNE. @*Conclusions@#In mainland China, the PNE prevalence among young adults was found to be high, and PNE had significant effects on physical and mental health. Risk factors included a family history, daytime voiding symptoms, and lack of treatment.

ABSTRACT

BACKGROUND@#Suicidal behaviors are seriously social issues among adolescents in the world. Exposed to smoking and being bullied are risk factors of suicidal behaviors. The present study was aimed to examine the interaction of smoking and being bullied on suicidal behaviors among Chinese adolescents.@*METHODS@#A total of 18,900 students were involved in the questionnaire study, in four cities of China from November 2017 to January 2018. Suicidal behaviors, smoking, and being bullied were measured by self-reported validated instruments. Chi-square tests and logistic regression were used to analyze the associations of suicidal ideation (SI)/suicidal plan (SP)/suicidal attempt (SA), smoking, and being bullied.@*RESULTS@#The prevalence of smoking, being bullied, SI/SP/SA, were 3.1%, 20.6%, 26.4%, 13.2%, and 5.2% respectively. Interaction analysis indicated that being bullied was associated with a greater increase in the likelihood of suicidal behaviors for adolescents with smoking than for those without smoking.@*CONCLUSIONS@#These finding suggest that smoking exacerbates the association between being bullied and suicidal behaviors. Future research should explore how and why smoking appears to more bully-victims than for those without smoking and how to mitigate it.

ABSTRACT

At present, the research of Moutan cortex carbonisata (MCC) mainly focuses on the changes of chemical composition before and after charcoal production, and there is a lack of material basic research directly related to the efficacy at home and abroad. In this study, Moutan cortex, as a precursor, and was calcined to MCC at high temperature. The Moutan cortex carbonisata nano-components (MCC-NCs) were extracted and separated from MCC to explore its cooling-blood and hemostatic effects. In the experiment, the MCC was calcined at a high temperature in a muffle furnace (350 ℃, 1 h), and then MCC-NCs were extracted for MCC, and characterized by transmission electron microscopy and UV-vis absorption spectroscopy, fluorescence spectroscopy, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. In addition, the study evaluated the blood-cooling and hemostatic effects of MCC-NCs. The results showed that MCC-NCs have a size distribution of 0.80-2.8 nm, a lattice spacing of 0.26 nm. MCC-NCs are mainly composed of C, O and N elements and have abundant surface functional groups such as OH, C=O, C-N and C=C. The fluorescence yield of MCC-NCs was 7.18%. The experiments complied with the Animal Ethics Committee of Beijing University of Chinese Medicine. The result indicated that pretreatment MCC-NCs can significantly (P < 0.05) reduce the high, medium, and low viscosity of whole blood and plasma viscosity, and reduce hematocrit, red blood cell distribution width, hemoglobin and red blood cell level. In addition, MCC-NCs significantly reduced the levels of activated partial thromboplastin time, thrombin time and fibrinogen (P < 0.05). The pathological examination results showed that MCC-NCs can significantly reduce lung tissue damage, reduce bleeding and inflammatory cell infiltration. At the same time, it can also significantly reduce the symptoms of gastric mucosal bleeding. In conclusion, the results indicated that MCC-NCs has significantly the effect of blood cooling and hemostasis, and its hemostatic effect is mainly related to the activation of endogenous coagulation pathway or fibrinogen system, which provided a novel strategy for exploring the material basis of traditional Chinese medicine for hemostasis.

ABSTRACT

OBJECTIVE:To study th e effects of dexmedetomidine on ventricular arrhythmia in myocardial hypertrophy model rabbits and the expression of calcium ion /calmodulin-dependent protein kinase Ⅱ(CaMKⅡ)in myocardial tissue of rabbits. METHODS: The rabbits were randomly divided into sham operation group , model group , dexmedetomidine low-dose , medium-dose and high-dose groups (10,25,50 μ g/kg),CaMK Ⅱ inhibitor KN- 93 group (10 mg/kg),high-dose of dexmedetomidine+KN-93 group(50 μg/kg+10 mg/kg),with 10 rabbits in each group. Except for the sham operation group ,other groups received abdominal aortic coarctation to induce myocardial hypertrophy model. After surgery ,administration groups were given relevant dose of dexmedetomidine or/and intraperitoneal injection of KN- 93;sham operation group and model group were given constant volume of normal saline intravenously ,once every other day ,for consecutive 8 weeks. After last medication , programmed stimulation was used to induce ventricular arrhythmia. The induction rate of early posterior depolarization (EAD)and tip torsion type ventricular tachycardia (Tdp)were recorded. Left ventricular ejection fraction (LVEF)and left ventricular shortener fraction(FS)were measured. QT interval ,transventricular wall repolarization dispersion (TDR)and transmembrane 90% action potential duration (APD90)of endocardial and epicardial cardiomyocytes in wedge-shaped myocardium were recorded. The ratio of heart weight to body weight (HW/BW)and the thickness of left ventricular wall (LVT)were measured and calculated. The cross-sectional area of cardiomyocytes ,mRNA expression of ANP and BNP as well as protein expression of CaMK Ⅱ and p-CaMK Ⅱ in myocardial tissue was measured. RESULTS :Compared with sham operation group ,the induction rate of EAD and Tdp ,HW/BM, LVT,mRNA expression of ANP and BNP and protein relative expression of CaMK Ⅱ and p-CaMK Ⅱ in cardiac tissue were all increased significantly ,while LVEF and FS were decreased significantly ;QT interval ,APD90 of endocardial and epicardial cardiomyocytes were all prolonged significantly ;TDR was increased significantly ,while cross-sectional area of cardiomyocytes was increased significantly in model group (P<0.05). Compared with model group ,induction rate of EAD and Tdp ,HW/BW (except for dexmedetomidine low-dose group ),LVT(except for dexmedetomidine low-dose group ),mRNA relative expression of ANP(except for dexmedetomidine low-dose group )and BNP (except for dexmedetomidine low-dose group )as well as protein relative expression of CaMK Ⅱ and p-CaMK Ⅱ were all decreased significantly in administration groups ;the levels of LVEF (except for dexmedetomidine low-dose group ) and FS (except for dexmedetomidine low-dose group ) were all increased significantly; QT interval ,APD90 of endocardial and epicardial cardiomyocytes were shortened significantly ; TDR and cross-sectional area of cardiomyocytes (except for dexmedetomidine low-dose group )were decreased significantly (P<0.05);the improvement effects of dexmedetomidine high-dose group were significantly better than those of dexmedetomidine low-dose and medium-dose groups (P<0.05). Compared with dexmedetomidine high-dose group and KN- 93 group,the improvement of above indexes were all more significant in high-dose of dexmedetomidine+KN- 93 group(P<0.05). CONCLUSIONS :Dexmedetomidine can reduce the induction rate of ventricular arrhythmia and improve myocardial hypertrophy in myocardial hypertrophy model rabbits,the mechanism of which may be associated with down-regulation of CaMK Ⅱ expression.

ABSTRACT

OBJECTIVE:To investigate the effects and mechanism of Jidesh eng anti-venom tablet on local wound inflammation and systemic inflammatory response of snake bite patients. METHODS :Totally 64 patients with snake bite admitted to our hospital during Jun. 2018-Jun. 2020 were randomly divided into control group and observation group ,with 32 cases in each group. Both groups received routine treatment ,such as debridement ,drainage,flushing,sealing,anti-venom,anti-infection,anti-fibrinolysis and anti-shock. Observation group was additionally given Jidesheng anti-venom tablet for internal and external use ,for consecutive 7 d. Related indexes of systemic inflammatory response ,local wound condition ,hospital stay ,laboratory indexes of important organs,coagulation function index ,wound inflammatory cell counts ,serum levels of inflammatory cytokines and chemokine ,the occurrence of ADR were compared between 2 groups. RESULTS :After treatment ,most of related indexes of systemic inflammatory response (RR,HR and WBC ),local wound condition (local pain disappearance time ,wound detumescence time ), hospital stay ,laboratory indexes of important organs (AST,ALT,Scr,BUN,CKB,CK-MB),coagulation function index (t-PA, PAI-1,TAT,SFMC),wound inflammatory cell (macrophages,neutrophils,lymphocytes)count,serum levels of inflammatory cytokines(TNF-α,IL-1,IL-6,hs-CRP,NF-κB)and chemokine (MCP-1,CXCL-8)in 2 groups were significantly better than before treatment (P<0.05);most indexes of observation group were significantly better than those of control group (P<0.05). No severe ADR was found in 2 groups. CONCLUSIONS :Jidesheng anti-venom tablet as auxiliary treatment can significantly reduce the local wound inflammation and systemic inflammatory response of snake bite patients ;the mechanism is probably related to reducing the levels of chemokine MCP- 1 and CXCL- 8 and inflammatory cytokines hs-CRP and NF-κB.

ABSTRACT

Objective:To study the effect of rotational errors on the positioning accuracy (PA) and to assess whether correcting rotation in patients with head-neck tumors in radiotherapy or not.Methods:The image information of 34 patients with head-neck tumors treated at Zhongnan Hospital of Wuhan University between August 2019 and January 2020 was collected. Mega-voltage computed tomography (MVCT) images of each patient were taken before radiotherapy, and were registered with planned kilo-voltage computed tomography (KVCT) images by two registration methods. All information was divided into control group (translation only) and intervention group (translation and rotation) according to different registration methods, there were 144 fractioned registered images for each group, respectively. The position errors of the two registration methods were recorded and compared. Data were carried out with Wilcoxon signed rank test and Spearman rank correlation.Results:Translational errors of the control group and the intervention group were 0.10 (5.35) mm and 0.00 (5.78) mm in right-left direction, and there was a statistically significant difference ( Z=-2.675, P=0.007); 0.75 (2.78) mm and 0.60 (2.68) mm in superior-inferior direction, and there was a statistically significant difference ( Z=-2.819, P=0.005); 0.10 (0.90) mm and 0.20 (1.28) mm in anterio-posterior direction, and there was a statistically significant difference ( Z=-3.984, P<0.001). Rotational errors of the intervention group were -0.20 (0.60)°, 0.35 (2.00)°, 0.00 (0.98)° in pitch, roll, yaw, respectively. The distribute of 3D vector corrected frequency for two groups was positively skewed. The corrected cumulative frequency (CCF) varied with 3D vector, 3D vector was 8.0 mm, and 19 F and 16 F fractioned treatments of the control group and the intervention group were not corrected, respectively; 3D vector was between 8.0-13.5 mm, the corrected tendency of the intervention group was slower and fractioned treatment was completed later. The analytical results of Spearman rank correlation showed that rotational errors in pitch were negatively correlated with translational errors of the control group in superior-inferior direction ( r=-0.182, P=0.029) and the intervention group in anterio-osterior direction ( r=-0.484, P<0.001); rotational errors in roll were negatively correlated with translational errors of the intervention group in right-left direction ( r=-0.334, P<0.001); rotational errors in yaw which were positively correlated with translational errors of the intervention group in right-left direction ( r=0.370, P<0.001) were negatively correlated with translational errors of the control group in superior-inferior direction ( r=-0.171, P=0.040) and the same was true for the intervention group ( r=-0.203, P=0.015); total angles were positively correlated and negatively correlated with translational errors of the control group in superior-inferior direction ( r=0.246, P=0.003) and anterio-posterior direction ( r=-0.188, P=0.024), and positively correlated with 3D vector of the control group ( r=0.198, P=0.017), total angles were positively correlated with translational errors of the intervention group in superior-inferior direction ( r=0.170, P=0.041) and with 3D vector of the intervention group ( r=0.239, P=0.004); there were no correlations between rotational errors and the other translational errors (all P>0.05). Conclusion:Although the corrected rotation increases translational errors in anterio-posterior direction and 3D vector, it improves PA for head-neck tumors in radiotherapy. When rotational errors are not corrected, rotational offsets are present with corrected translation to decrease its effect on PA.

ABSTRACT

The tasks and directions of occupational health works in the new era mainly include three aspects: actions for pneumoconiosis prevention and treatment, risk assessment of occupational health and construction of healthy enterprises. These three aspects exist independently, but they are interrelated, constituting the work support, reflecting the work characteristics, features and direction of different stages of occupational health works. It is necessary to establish a new of ″trinity″ with these three aspects of occupational health works, emphasize the prevention and treatment of pneumoconiosis, promote the occupational health risk assessment and the construction of healthy enterprises. However, as poverty alleviation becomes a past, occupational health risk assessment might be underestimated, and the construction of healthy enterprises might be neglected, the task of occupational health remains laborious. Accelerating the implementation of occupational health protection action is a requirement of the era. It is also the direction of occupational disease prevention and treatment, and the duty of occupational prevention personnel, that must be fully promoted in the right direction.
