Objective To assess the effects of Danhong injection on the perfusion function of the pancreas in patients with acute pancreatitis (AP). Methods A total of 102 patients with AP were collected, and there were 25 patients with severe acute pancreatitis ( SAP) and 77 patients with mild acute pancreatitis (MAP). They were randomly divided into routine treatment group ( RTG,n =54) and Danhong treatment group (DTG,n =48) , respectively. Another 33 normal individuals were used as controls. Patients in RTG received gastric decompression, acid inhibition, anti-infection and nutritional support. Patients in DTG received Danhong injection 30 ml i. v. b. i. d besides routine treatment. The hemodynamic parameters ( BF, BV, MTT, and PS) of perfusion of the pancreas were measured by 16-slice spiral CT scanner. Results The values of BF of control, MAP, SAP group were time was ( 12.6 ± 2.7) d in DTG, which were significantly shorter than those in routine treatment group [(14.5 ±3.2)d, (18.5 ±5.5)d, P <0.05]. Conclusions The parameters of CT perfusion imaging of the pancreas can be a quantitative criterion to assess the severity of microcirculation dysfunction in patients with AP, and Danhong injection is effective to improve the blood perfusion of the pancreas during the treatment of AP.

AIM: To investigate the effect of 7-(4-methoxyphenyl)-5, 8a-diphenyl-1,2, 3, 7, 8, 8a-hexahydroimidazo[1,2-a] pyridine (TIP-6) on cell proliferation in human hepatoma cell line HepG2 and human normal hepatocyte cell line L02. METHODS: Typan blue assay was used to check the effect of TIP-6 on cell proliferation. The changes of cell morphology were observed by the phase contrast microscope. Flow cytometry (FCM) was used to check cell cycle. Autophagy and autophagic cell death were detected after acridine orange (AO) staining under fluorescent microscopy. Apoptosis was analyzed by Annexin V/7-AAD, DAPI staining and DNA ladder. NF-κB expression was detected with cellular immunochemistry. RESULTS: Cell proliferation inhibiting effect was appeared when treated with TIP6 from 60 μmol/L to 200 μmol/L, which was correlated with treated concentrations and time. The proliferation rates were just 12.10% and 18.75% (vs control) under 200 μmol/L 72 h in HepG2 and L02 respectively. Vacuolization were found more and more frequently with the increasing of TIP-6 concentrations and treated time prolonged. FCM results indicated that cells were blocked in G2/M phase, and more sensitive were found in HepG2 than L02. AO staining results indicated that the phenomenon of autophagy and autophagic cell death were occurred and appeared more potent with more TIP-6 and longer time treated. No apoptosis markers were found with Annexin V/7-AAD and DAPI staining, and no DNA ladders were found either, these indicated that TIP6 didnt induce apoptosis in these cells. NF-κB was found increased after treated with TIP-6, and the autophagic vacuole became more and more with the increasing of NF-κB protein, but the proliferation rates decreased at the same time. CONCLUSION: TIP-6 inhibited cell proliferation and induced autophagy and autophagic cell death in HepG2 and L02 cells. NF-κB activation may be involved in these effects.

Objective To investigate the effects of metabolically correlated factors on pig renal tubule in cellular level by observing effects of glucose,insulin and uric acid on activity of haemachrome oxygenase in renal tubular epithelial cells.Methods Pig near renal tubular cell line(LLC-PK1) was selected as experimental object.After stimulating cells respectively with glucose(5,10,22,33mmol/L),uric acid(0,0.1,0.2,0.4mmol/L);and insulin(0,10~(-9),0~(-8),10~(-7)mol/L) in different concentrations for 48 hours,the activity of HO-1 within the cells was determined.Results In uric acid group the activity of HO-1 was significantly increased in a concentration-dependent manner,while in glucose and insulin groups,the activity of HO-1 did not change.Conclusion After LLC-PK1 was stimulated by uric acid of different concentrations,HO-1 was induced evidently,which indicates that uric acid might affect oxidative stress in renal tubule cell line.

Objective To investigate the clinicopathological features and prognostic factors in patients with low grade glioma. Methods Eighty- seven patients with low grade glioma confirmed by cytological examination were retrospectively analyzed. Results Among 87 patients, male accounted for 62.1%(54/87), and the average age was 36.2 years. The average followed- up time was 51.4 months (3-135 months), and 5 cases were lost in follow-up. The follow- up rate was 94.3% (82/87). The 3- year survival rate was 84.1%, and the 5- year survival rate was 66.7%. The 3- year survival rate was related to clinical symptoms, maximum diameter of tumor and the extent of resection (P<0.01 or<0.05);and the 5- year survival rate was related to years, Karnofsky score, clinical symptoms, maximum diameter of tumor, the pathology classification and extent of resection (P<0.05 or<0.01). Conclusions Low grade glioma is more common in male patients and patients under the age of 40 years. Age below 40 years, Karnofsky score ≥ 70 scores, only epilepsy symptom, tumor diameter below 6.0 cm, oligodendrogliomas, complete resection or subtotal resection are positive prognostic factors. Postoperative radiotherapy can reduce the rate of tumor progression.

Objective To investigate the efficacy and application of bronchoalveolar lavage in chil-dren with severe pneumonia undergoing mechanical ventilation. Methods Using a prospective randomized controlled clinical study, 202 children with severe pneumonia received mechanical ventilation in Hunan Children′s Hospital from January 2016 to January 2018 were selected as the subjects. According to the digital method,all cases were divided into treatment group (101 cases) and control group (101 cases) randomly. The patients in the control group were given conventional treatment ( anti-infection and symptomatic thera-py) . The treatment group was treated with bronchoalveolar lavage on the basis of conventional treatment. The basic situation,the respiratory function before and after the treatment,the inflammation index,the curative effect and the prognosis of two groups were analyzed. Results There were no significant differences between the two groups in gender,age,course pre-admission,pediatric critical illness score,respiratory function and in-flammation index ( P>0. 05 ) . The respiratory function indexes of the treatment group were obviously im-proved 2 hours after the treatment and the PaO2 ,PaO2/FiO2 and SaO2 were significantly higher than those of the control group[PaO2:(82. 4 ± 6. 4) mmHg(1 mmHg=0. 133 kPa) vs. (74. 0 ± 5. 5) mmHg, PaO2/FiO2:(360. 2 ± 21. 3) mmHg vs. (332. 6 ± 23. 5) mmHg,SaO2:(94. 9 ± 8. 2)％ vs. (88. 6 ± 10. 3)％], while the PaCO2 were significantly lower than the control group [ ( 37. 3 ± 10. 3 ) mmHg vs. ( 45. 8 ± 5. 5 ) mmHg],and the differences were statistically significant (P<0. 05). Five days after treatment,the WBC, PCT and CRP of treatment group were significantly lower than those in the control group[WBC:(8. 5 ± 2. 4) × 109/L vs. (11. 7 ± 3. 5) × 109/L,PCT:(1. 2 ± 0. 7) μg/L vs. (2. 3 ± 0. 9) μg/L,CRP:(9. 1 ± 3. 2) mg/L vs. (16. 5 ± 4. 7) mg/L,P<0. 05,respectively]. The total effective rate in the treatment group was significantly higher than that in the control group[93. 1％(94/101)vs. 81. 2％(82/101)]. Mechanical venti-lation duration and PICU stay in treatment group were significantly shorter than those in the control group [(148. 5 ±30. 6)h vs. (159. 6 ±47. 3)h,(220. 8 ±49. 7)h vs. (330. 7 ±94. 6)h]. The positive rate of patho-genic bacteria was significantly higher than that in the control group [79. 2％(80/101)vs. 62. 4％(63/101), P<0. 05],but there was no significant difference in the 28 days mortality of the two groups[5. 0％(5/101) vs. 5. 9％(6/101),P>0. 05]. Conclusion The bronchoalveolar lavage can improve the respiratory func-tion,reduce the inflammatory reaction,shorten mechanical ventilation duration and PICU stay in children with severe pneumonia undergoing mechanical ventilation obviously. It is worth popularizing in the PICU because of the improvement of curative effect in these children.

Objective To explore the changes of SOX9 and WT1 expressions in rat Sertoli cells irradiated by EMP ( electromagnetic pulse),S-HPM ( S-band high power microwave) and X-HPM ( Xband high power microwave).Methods Primary Sertoli cells were isolated from 3-week-old Wistar rats and its purity was immunocytochemistrically indentified with WT1.After exposure to 6 × 104 V/m EMP,100 mW/cm2 S-HPM and X-HPM for 4 min respectively,SOX9 and WT1 expressions in Sertoli cells were determined with real-time PCR and Western blot,respectively.Results SOX9 mRNA expression was decreased at 6 and 12 h post-irradiation of three different bands of electromagnetic microwave ( F =15.20and 4.84,P ＜ 0.05 ).SOX9 protein expression was also decreased at 6 and 24 h after irradiation ( F =8.46 and 7.47,P＜0.05).WT1 mRNA expression was decreased at6 and 12 h (F=13.46 and 5.08,P ＜ 0.05 ),but its protein expression was decreased only at 24 h post-irradiation ( F =10.26,P ＜ 0.05 ).Conclusions Three bands of electromagnetic radiation reduce the expressions of SOX9 and WT1 in rat Sertoli cells,which may provide molecular foundation for genital system hazards induced by microwave radiation.

Objective To analysis the correlation between the vulnerability of carotid plaque and ischemic stroke and to explore the clinical significance of assessing vulnerable plaques accurately.Methods A total of 64 patients,who underwent carotid endarterectomy (CEA) in First Affiliated Hospital of Soochow University from October 2014 to February 2016,were classified into ischemic and non-ischemic stroke group according to whether ischemic stroke symptoms occurred during the last 6 months before surgery.To judge the stable and vulnerable plaques,the patients underwent carotid doppler ultrasonography (CDU) before surgery,and the carotid plaques were evaluated with HE staining after CEA.We also analyzed the risk factors of plaque formation and the relevance between the plaque characteristic and ischemic stroke with chi-square test.Kappa test were used to analyze the consistency of CDU and pathology.Results Of the 44 cases in ischemic stroke group,CDU identified 81.8％ (36/44) vulnerable plaques and 18.2％ (8/44) stable plaques,while pathology confirmed 86.4％ (38/44) vulnerable plaques and 13.6％ (6/44) stable plaques.Of the 20 cases in non-ischemic stroke group,CDU identified 35％ (7/20) vulnerable plaques and 65％ (13/20) stable plaques,while pathology confirmed 40％ (8/20) vulnerable plaques and 60％ (12/20) stable plaques.In both CDU and pathology,vulnerable plaques in ischemic stroke group were obviously higher than that in non-ischemia group (x2=13.67,P ＜ 0.001;x2=14.62,P ＜ 0.001).The results of CDU agreed well to that of pathology results (Kappa=0.669,P ＜ 0.01).Conclusions The vulnerability of plaques were closely related to the ischemic stroke.CDU is a reliable examination method to identify vulnerable plaques.The accurate assessment of vulnerability of plaques has a great significance in preventing ischemic stroke.

Objective: To assess the efficiency and safety of low-dose decitabine in patients with lower-risk myelodysplastic syndrome (MDS) to couple with the clinical significance of MDS-related gene mutations. Methods: This study was done in 4 institutions in Zhejiang Province. A total of 62 newly diagnosed patients with lower-risk MDS were assigned to two groups of decitabine (12 mg·m^-2·d^-1 for 5 consecutive days) and best supportive care (BSC) . Their bone marrow samples were subject to examinations of MDS-related 15 gene mutations. The primary endpoints were the proportion of patients who achieved overall response (ORR) after at least two cycles and progression-free survival (PFS) , and their relevances to the gene mutations. Results: Of 62 enrolled patients, and 51 cases were included in the final analysis. 16 of 24 patients (66.7%) in decitabine group achieved ORR versus 8 of 27 (29.6%) in BSC group (χ²=6.996, P=0.008) ; PFS prolongation of decitabine versus BSC was statistically significant (not reached vs 13.7 months, P=0.037) . Among 51 patients, at least one gene mutation was identified in 20 patients (39.2%) , including 4 single SF3B1 mutation. PFS in cases with gene mutations (not including single SF3B1 mutation) was significantly shorter than of no gene mutation (9.2 months vs 18.5 months, P=0.008) , but not for ORR (37.5% vs 58.1%, P=0.181) . Among 16 patients with mutated genes, ORR in decitabine and BSC groups were 75% (6/8) and 0 (0/8) , respectively. The most adverse events in decitabine group were grade 3 to 4 neutropenia (45.8%) and grade 3 to 4 infections (33.3%) . Conclusion This preliminary study showed that low-dose decitabine produced promising results with an acceptable safety in lower-risk MDS patients, especially for those with mutated genes. Further study targeting poor prognostic lower-risk MDS patients should be warranted.

Objective:To investigate the clinical characteristics of patients with rheumatic diseases and abnormal liver function, as well as determine the proportion and severity of liver function abnormalities.Methods:Cross-sectional study. Data were collected from patients registered in the Chinese Rheumatism Date Center from 2011 to 2021. The rheumatic diseases analyzed in this study were rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjogren syndrome (SS), ankylosing spondylitis (AS), and gout. Patient data, including demographic characteristics [ such as age, sex, body mass index,(BMI), and smoking history], liver function test results [including alanine aminotransferase (ALT), aspartate aminotransferase, alkaline phosphatase(ALP), and total bilirubin], and use of anti-rheumatic immune drugs and liver-protective drugs, were collected and compared between groups with normal and abnormal liver functions. In addition, the proportions of abnormal liver function were compared between sex and age groups.Results:A total of 116 308 patients were included in this study, including 49 659 with RA, 17 597 with SLE, 9 039 with SS, 11 321 with AS, and 28 692 with gout. The lowest proportion of liver function abnormalities was observed in patients with RA[11.02% (5 470/49 659)], followed by those with SS[17.97% (1 624/9 039)] and AS [18.22% (2 063/11 321) ], whereas patients with SLE [21.14% (3 720/17 597) ] and gout [28.73% (8 242/28 692)] exhibited the highest proportion of these abnormalities. Elevated ALT, mostly classified as grade 1, was the most commonly noted liver function abnormality, whereas elevated ALP was the least common. Some patients who took liver-protective drugs had normal liver function, with the lowest percentage observed in patients with gout [7.45% (36/483) ] and ranging from 21.7% to 30.34% in patients with RA, SLE, SS, and AS. The proportion of liver function abnormalities was higher in males than in females for all disease types [RA: 13.8%(1 368/9 906) vs. 10.3%(4 102/39 753); SLE: 33.6% (479/1 424) vs. 20.0% (3 241/16 173); SS: 25.4%(111/437) vs. 17.6%(1 513/8 602); AS: 20.1%(1 629/8 119) vs. 13.6% (434/3 202); and gout: 29.3% (8 033/27 394) vs. 16.1% (209/1 298)]. In RA, SLE, and AS, the proportions of liver function abnormalities were similar across all age groups. In SS, the proportion of liver function abnormalities increased with age [<40 years: 14.9%(294/1 979); 40-59 years: 18.1%(858/4 741); ≥60 years: 20.4%(472/2 319)], whereas a reversal of this trend was observed in gout [<40 years: 34.9%(4 294/12 320); 40-59 years: 25.5%(2 905/11 398);≥60 years: 21.0%(1 042/4 971)].Conclusions:The proportions of combined liver function abnormalities in patients with rheumatologic diseases were high, and the utilization rates of liver-protective drugs were low. It is necessary to pay more attention to monitoring patients′ liver function, timely administer liver-protective drugs, and optimize liver-protective regimens during the treatment of rheumatic diseases.
