OBJECTIVE: To investigate the curative effects of nanometer silver dressing and recombinant bovine basic fibroblast growth factor gel on burn residual wounds.METHODS: Forty burn patients with residual wounds because of deep second degree burn and full-thickness burn, were randomly divided into control group and management group. There were 20 patients in both groups. The patients of management group were treated by nanometer silver dressing and recombinant bovine basic fibroblast growth factor gel. The patients of control group were treated by saline and paraffin absorbent gauze. Healing time, wound healing rates at different time points,cases of infected wound and results of bacterial culture before and 7 days following treatment, and drug adverse reaction were recorded.RESULTS: The healing time of management group was significantly shorter than the control group (P < 0.01). The wound healing rates of management group was significantly higher than the control group at different time points (P< 0.01). The cases of infected wound was significantly fewer than the control group after treating (P < 0.01). The pathogenic bacteria detection rate was significantly lower than the control group after 7 days (P < 0.01).CONCLUSION: There was better antibacterial activity, decurtating the healing time when the management of nanometer silver dressing and recombinant bovine basic fibroblast growth factor gel on burn residual wounds were put into practice.

Objective To evaluate the clinical efficacy and safety of compound polymyxin B ointment combined with desonide cream for the treatment of subacute or chronic eczema. Methods A multicenter, randomized, double?blind, parallel?group, controlled clinical study was conducted. Totally, 144 patients with subacute eczema and 144 patients with chronic eczema were enrolled into this study, and both randomly and equally divided into the test group and control group. The test group and control group firstly topically applied compound polymyxin B ointment and its vehicle respectively, then both topically applied desonide cream 3 hours later. The drugs or vehicle were applied twice a day in all the patients. Patients′ symptoms and signs (including degree of itching, inflammation, erosion/exudation and infiltration/thickening, as well as area of target lesions) were evaluated, and the time to onset and duration of itching?alleviating effect were recorded. The clinical efficacy and safety of treatments were analyzed and compared between the test group and control group. Results The total symptom and sign scores significantly decreased to different extents on days 7 and 14 in the test group(subacute eczema patients:6.09 ± 2.78 and 3.68 ± 3.18 vs. 13.44 ± 1.66; chronic eczema patients: 6.56 ± 2.68 and 4.38 ± 3.27 vs. 12.96 ± 1.16)and control group(subacute eczema patients:8.26 ± 3.17 and 5.28 ± 4.05 vs. 13.60 ± 1.75;chronic eczema patients: 8.84 ± 2.90 and 6.25 ± 3.78 and vs. 12.64 ± 1.18)compared with those at baseline. Moreover, the total symptom and sign score of patients with subacute or chronic eczema was significantly lower in the test group than in the control group on days 7 and 14(all P<0.05). A significant increment was observed in the degree of decrease in scores for itch, infiltration/thickening in patients with subacute eczema in the test group compared with that in the control group(all P<0.01), as well as in scores for itch, infiltration/thickening and area of target lesions in patients with chronic eczema in the test group compared with those in the control group (all P < 0.05). In addition, patients with subacute eczema in the test group showed significantly shorter onset and longer duration of itching?alleviating effect than those in the control group(both P<0.05). The time to onset of itching?alleviating effect was also significantly shorter in patients with chronic eczema in the test group than in those in the control group(P<0.000 1), but there was no significant difference in the duration of it between the two groups of patients with chronic eczema. Clinicians and patients were both more satisfied with therapeutic effects in the test group than in the control group(all P<0.05). Conclusions Topical compound polymyxin B ointment can increase the efficacy of topical desonide cream for the treatment of subacute or chronic eczema, especially subacute eczema. Compound polymyxin B ointment also shows a favorable therapeutic effect on itching and infiltration/thickening in patients with eczema.

Objectives To analyze the changes of serum complement C1q level in patients with metabolic syndrome (MS) and investigate whether it is associated with lipid metabolism and glycometabolism. Methods In a cross-sectional study, the subjects were selected as the patients and healthy people who went to the second xiangya hospital of central south university from July 2017 to June 2018. A total of 152 MS patients were enrolled and another 90 healthy subjects were enrolled as control group. Anthropometry parameters such as body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP) were measured. Serum concentrations of C1q and other biochemical indexes including blood glucose (GLU), triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were measured in all groups. The correlations between C1q and these parameters were analyzed by spearman's rho test and the clinical value of C1q in predicting MS was further evaluated by stepwise multiple linear regression analysis. Results MS group had higher serum C1q levels (244.34±62.66) mg/L compared with the control group (202.37±35.92) mg/L (t=-6.250, P=0.000). C1q levels (244.34±62.66) mg/L were positively associated with TG levels [2.34(1.89, 3.62)] mmol/L (r=0.245, P=0.001), TC levels (4.91±1.26) mmol/L (r=0.398, P=0.000), LDL-C levels (3.23±1.03) mmol/L (r=0.325, P=0.000) in MS group, While C1q levels (258.92±69.59)mg/L were positively associated with SBP (144.76 ± 22.94) mmHg (r=0.388, P=0.018), TG levels [2.65(1.87, 3.82)] mmol / L (r=0.482, P=0.003), TC levels (5.18±1.31) mmol/L (r=0.529,P=0.001) in MS patients with obesity. The stepwise multiple regression analysis showed that TG levels were independently correlated with serum C1q levels both in MS patients (β=0.302, P=0.000) and in MS patients with obesity (β=0.653, P=0.000) after adjusting for age, gender and other biochemical markers. Conclusions MS patients had higher C1q levels than healthy subjects and serum C1q levels were closely positive related to harmful lipid profiles. Serum TG level was an independent influencing factor of serum C1q in MS patients.

Objective To investigate the level of serum lipoprotein-associated phospholipase A2(Lp-PLA2) activity in healthy adults of Changsha area and establish the reference interval of serum Lp-PLA2activity. Methods A total of 424 healthy adults (175 males and 249 females) were classified into five groups by different age, including 20 to 29, 30 to 39, 40 to 49, 50 to 59 and over 60 years old group. Serum Lp-PLA2activity was measured by continuous-monitoring assay. According to the requirements of Clinical and Laboratory Standards Institute (CLSI) C28-A3, the reference interval of Lp-PLA2activity was established by nonparametric method.Results The levels of serum Lp-PLA2activities in both males and females showed normal distribution. The average of Lp-PLA2activity was (478± 135)U/L in 175 males and (402±116)U/L in 249 females with statistically significant difference (t＝6.184, P＜0.01). Z test result showed Z＞Z?, so the reference intervals of males and females were established respectively. There was no statistical difference of Lp-PLA2activities among the varied groups of males (F＝1.259, P＝0.288), but there were statistical differences among the varied groups of females (F＝9.341, P＜0.01). The females of the age over 40 years old showed higher activities than those of age under 40 years old (t＝5.732,P＜0.01). However, there was no statistical significance of serum Lp-PLA2activities in the females between the two groups of the age under 40 and the three groups of age over 40. Therefore, the reference intervals of serum Lp-PLA2activities in healthy adults were established as followed: 217-761 U/L for males, 168-566 U/L for the females of 20 to 39 years old and 203-702 U/L for the fe-males of 40 to 86 years old. Conclusion The reference interval of serum Lp-PLA2activity in physical examination of healthy adults in Changsha area was established.

OBJECTIVE: To observe the change of serum homocysteine (Hcy) and anti-citrullinated peptide (CCP) antibody concentration in depression rat model induced by chronic unpredictable mild stress (CUMS), and to explore the immunologic mechanism of depression and the relation between depression and its autoimmunity. METHODS: Sixty adult male SD rats were randomly divided into 2 groups, 30 rats in each group, which were divided into 3 subgroups: a normal control group, a model group and a fluoxetinetreated group. The depression rat model was established under CUMS and seperated feeding, after which, open field, sugar consumption and forced swimming test were applied in the first group. After the blood was taken in the second group of rats through heart puncture, the level of serum Hcy was detected by enzymatic cycling assay and serum anti-CCP antibody by ELISA. RESULTS: Compared with the control group and the fluoxetine treatment group, spontaneous activity and sucrose consumption and preference percentage of the rats in the model group significantly reduced, while the immobility time in forced swimming test and the level of Hcy and anti-CCP antibody in the rat serum significantly increased. CONCLUSION Immunity inflammation and autoimmune reaction exist in CUMS depression model rats, and fluoxetine treatment can improve these immune response.

Objective:The results of the three lipid detection systems were compared to analyze their influence on risk stratification and clinical treatment in lipid management, especially the target goal cut-off point determination, and to find ways to reduce the impact on target goal determination of various lipid measurement system.Methods:A total of 196 serum samples with triglyceride TG <4.5 mmol/L were collected from people undergoing physical examinations and in-patients in the Second Xiangya Hospital of Central South University from August to October 2022. Triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were directly detected with Hitachi-Woke (HW), Roche and Mindray detection systems, respectively. The non high-density lipoprotein cholesterol (non HDL-C) was calculated by formula (TC-HDL-C) and LDL-C (F-LDL-C) was calculated by Friedewald formula, and results from various methodology were compared. The coefficient of variation ( CV) of these six indicators derived from the three detection systems were calculated to evaluate the consistency of the obtained results from different venders. In addition, the Pearson correlation coefficient was analyzed to evaluate the correlation of each indicator among different systems. According to the Chinese Guidelines for Blood Lipid Management, samples were divided into groups with LDL-C levels of <1.4, 1.4-<1.8, 1.8-<2.6, 2.6-<3.4 and ≥3.4 mmol/L according to the recommended LDL-C levels for different risk stratification levels. The sample size and percentage of LDL-C test results from different systems in the same group were counted to evaluate the impact of LDL-C differences between systems on clinical decision-making of blood lipid management. The correction factor was calculated through two methods: (1) The average deviation of LDL-C between systems was estimated by EP9-A3 method; (2) Multiple linear stepwise regression was used to establish the regression model of LDL-C difference and related indexes between systems. The two correction factors were used to correct the deviation of LDL-C value obtained from various systems, and Chi-square test was used to compare the difference of LDL-C grouping consistency rate before and after correction. Result:The average CV values of TG, TC, LDL-C, F-LDL-C, HDL-C, and non HDL-C among the three detection systems were 4.84%, 1.92%, 11.96%, 3.81%, 5.82% and 2.61%, respectively. Correlation analysis showed that when comparing the three systems in pairs, except for LDL-C derived from HW and Roche′s, and Mindray and Roche′s LDL-C ( R 2=0.938 and 0.947), the R 2 of other indicators were all greater than 0.97. The consistency rates of the three systems on LDL-C and F-LDL-C were 51.0% (100/196) and 90.8% (178/196), respectively, according to the risk stratification standard values and the difference was statistically significant ( P<0.05). When comparing in pairs, the consistency rates of Roche and HW, Mindray and HW, Mindray and Roche system LDL-C grouping were 60.7% (119/196), 82.7% (162/196), and 54.1% (106/196), respectively. After adjusting for mean deviation, the group consistency rate of Roche and HW increased to 73.7%-79.4% ( P<0.05), and the group consistency rate of Roche and Mindray increased to 72.3%-79.0% ( P<0.05). After adjusting for difference regression model, the group consistency rate of Roche and HW increased to 82.5%-84.0%, and the group consistency rate of Roche and Mindray increased to 81.0%-89.2%. However, there was no significant change in the group consistency rate of Mindray and HW after adjusting for both correction methods ( P>0.05) .Conclusions:There are significant differences in LDL-C derived from different detection systems, and the consistency rate of grouping according to the lipid-lowering standard value is relatively low, which may affect clinical decision-making in lipid management. Adjusted by the correction factor, the consistency rate of grouping between Roche and HW, Roche and Mindray systems with large differences in LDL-C can be improved. Using the difference multiple linear regression model as a correction factor is superior to the average deviation.

Objective: In this study, black tea and Citrus maxima (BT-CM), yellow tea and C. maxima (YT-CM), green tea and C. maxima (GT-CM) as subjects, the active ingredient content and antioxidant activity of three tea and C. maxima (T-CM) were analyzed. The effects of three T-CMs on apoptosis of liver cells in vitro and its mechanism were further explored. Methods: National standard method and HPLC were used for active ingredient analysis. MTT, cell flow cytometry and Western blot were used to analyze the effects of three T-CMs on cell proliferation, apoptosis, and its underlying molecular mechanism. Results: The content of tea polyphenols, free amino acids, ratio of polyphenols and amino acids, ester catechins, non-ester catechins and caffeine in YT-CM and GT-CM was significantly higher than that of BT-CM. The in vitro antioxidant capacity of YT-CM and GT-CM was also significantly stronger than that of BT-CM. Three T-CMs had the effects of inhibiting proliferation, arresting cell cycle and inducing apoptosis in HepG2 and Bel7402 cells, especially YT-CM and GT-CM. Western blot analysis showed three T-CMs activated PI3K/AKT/mTOR signaling pathway and regulated the expression levels of apoptosis-related proteins Bax, Bcl-2 and Caspase-3/9. YT-CM and GT-CM had better ability to change the signal pathway than BT-CM. Conclusion: In short, T-CMs, which combined different degrees of fermentation tea with C. maxima, were rich in nutrients and biologically active substances. T-CMs, especially YT-CM and GT-CM, are healthy drinks that help to prevent and treat liver cancer.
