ABSTRACT

ObjectiveTo investigate the effect of Yiqi Tongxin formula (YQTM) on liver inflammation in apolipoprotein E-∕- (ApoE-∕-) mice by regulating the nuclear transcription factor-κB (NF-κB)/NOD-like receptor protein 3 (NLRP3) signaling pathway. MethodForty ApoE-∕- mice were randomly divided into a model group, an atorvastatin group (positive drug group), and low-, medium-, and high-dose YQTM groups (0.39, 0.78, 1.56 g·kg-1). Each drug administration group was given the corresponding concentration of the drug by gavage on the basis of high-fat feeding for 12 consecutive weeks. Eight C57BL/6J mice were used as a blank group and fed with normal chow. After 12 weeks, oil red O staining and Masson staining were used to observe the aortic lesions in mice and to determine whether the modeling was successful. Oil red O staining was used to observe the lipidosis in the livers of mice. Hematoxylin-eosin (HE) staining was used to observe the tissue lesions in the livers of mice. Masson staining was used to observe the distribution of collagen fibers in the livers of mice. Enzyme markers were used to detect the total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) in mouse serum, as well as total cholesterol (TC) and triglyceride (TG) in the liver. Interleukin-1β (IL-1β) and IL-18 were detected in mouse liver by enzyme-linked immunosorbent assay (ELISA). Immunohistochemistry (IHC) was utilized to observe the expression regions of NF-κB and NLRP3 in the livers of mice. Western blot was employed to detect the protein expression levels of NF-κB, NF-κB inhibitory protein (IκB), IκB kinase β (IKKβ), phosphorylated NF-κB (p-NF-κB), phosphorylated IκB (p-IκB), phosphorylated IKK β (p-IKKβ), NLRP3, and Caspase-1 in the livers of mice. ResultCompared with the blank group, the model group showed severe aortic lipidosis, and the intracellular fat droplets in the livers aggregated in large quantities. The cytoplasm was filled with fat vacuoles(P<0.01). The serum levels of TG, TC, LDL-C, AST, and ALT were significantly elevated in the mice(P<0.01). TG and TC levels were elevated in the liver(P<0.01). The levels of IL-1β and IL-18 in liver tissue, as well as the protein expression levels of NF-κB, IκB, IKKβ, p-NF-κB, p-IκB, p-IKKβ, NLRP3, and Caspase-1 in the liver were significantly elevated(P<0.01). Compared with the model group, the aortic arch plaques of mice in each YQTM group were attenuated, and the fat aggregation in the liver was reduced. The inflammatory cell infiltration was alleviated(P<0.05,P<0.01). The serum levels of TG, TC, LDL-C, AST, and ALT were significantly reduced(P<0.05,P<0.01). TG and TC levels in the liver were reduced. The IL-1β and IL-18 levels in liver tissue, as well as protein expression levels of NF-κB, IκB, IKKβ, p-NF-κB, p-IκB, p-IKKβ, NLRP3, and Caspase-1 in the liver were significantly reduced(P<0.05,P<0.01). ConclusionThe intervention mechanism of YQTM on liver inflammation in ApoE-∕- mice may be related to the down-regulation of the NF-κB/NLRP3 signaling pathway.

ABSTRACT

Objective:To analyze the impact of baseline quantification of hepatitis B core antibody (qHBcAb) on prognosis of patients with hepatitis B virus (HBV) related acute-on-chronic liver failure (HBV-ACLF).Methods:A total of 91 HBV-ACLF patients (HBV-ACLF group), who admitted to Wuxi No.5 People′s Hospital from July 1, 2019 to December 30, 2021, were included in this study. Fifty chronic hepatitis B (CHB) patients (CHB group) and 50 chronic HBV carriers (HBV carrier group) were enrolled as controls. Baseline clinical data such as qHBcAb, blood routine examination biochemical, and coagulation indices, HBsAg, hepatitis B e antigen (HBeAg), HBV DNA levels were recorded and analyzed retrospectively. The HBV-ACLF, HBsAg and HBV-DNA data were converted logarithmically. Patients were followed-up for 90 days. Cox regression was used to analyze the correlation between HBV-ACLF and survival outcome; survival rate was estimated by the Kaplan-Meier method; receiver operating characteristic (ROC) curve was used to evaluate the predictive value of baseline qHBcAb for the prognosis in patients with HBV-ACLF.Results:The baseline qHBcAb level in HBV-ACLF patients was (4.83±0.42) IU/ml, which was significantly higher than that in the CHB group [(4.59±0.54) IU/ml] and chronic HBV carrier group [(3.86±0.74) IU/ml] (all P<0.05). At the end of 90 days follow-up, 46 patients (50.55%) survived, and 45 patients (49.45%) died in the HBV-ACLF group. The baseline qHBcAb level was significantly higher in the survival group [(4.93±0.22) IU/ml] than in the death group [(4.70±0.52) IU/ml, P<0.01]. Significant differences were also found in the alpha fetoprotein, international normalized ratio, prothrombin activity, antithrombin Ⅲ activity, platelet, end-stage liver disease model score and hepatic encephalopathy complication between the two groups ( P<0.05). Cox regression analysis showed that the baseline qHBcAb was an independent risk factor affecting the 90-day survival of HBV-ACLF patients [hazard ratio=0.027,95% confidence interval ( CI) 0.001-0.696, P<0.05]. The area under the ROC curve of baseline qHBcAb level for predicting the 90-day survival outcome of HBV-ACLF patients was 0.639 (95% CI 0.525-0.752, P<0.05), with a cut-off value of 4.89 IU/ml. The cumulative survival rate of patients with baseline qHBcAb≥4.89 IU/ml was higher than that of patients with baseline qHBcAb<4.89 IU/ml ( P<0.05). Conclusions:Higher baseline qHBcAb level is associated with favorable outcome of HBV-ACLF patients and baseline qHBcAb may be used as a new biomarker to predict the clinical outcome of HBV-ACLF patients. HBV-ACLF patients with serum qHBcAb lower than 4.89 IU/ml face increased risk of short-term death.

ABSTRACT

Objective:To explore the therapeutic effect of multi-mode sequential combination of artificial liver in the treatment of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).Methods:The clinical data of HBV-ACLF patients treated with artificial liver in Wuxi Fifth People′s Hospital from January 2018 to June 2021 were retrospectively analyzed. Eighty-six patients were divided into artificial liver multi-mode sequential combination therapy group (sequential combination group) and conventional treatment group. The cytokine level changes and model for end-stage liver disease (MELD) score were analyzed at 14 days of disease duration. The survival outcome and complications of artificial liver were analyzed after 30 days of follow-up. Two independent samples t test and chi-square test were used for statistical analysis. Cox regression analysis was used to analyze the risk factors of death, and Kaplan-Meier method was used to analyze the survival rate of patients. Results:A total of 86 patients were enrolled, including 48 patients in sequential combination group with the average number of artificial liver of 4.68 times/person, and 38 patients in conventional treatment group with the average number of artificial liver of 3.17 times/person. At 14 days of disease duration, interleukin (IL)-6, IL-8, interferon γ-inducible protein (IP)-10 level and MELD score in sequential combination group decreased significantly than those in the conventional treatment group ( t=3.80, 3.62, 4.95 and 1.11, respectively, all P<0.050). After 30 days of follow-up, 63 patients survived and 23 patients died. Cox regression analysis showed that baseline international normalized ratio (hazard ratio ( HR)=0.558, 95% confidence interval ( CI) 0.193 to 0.856, P=0.027), baseline antithrombin Ⅲ activity ( HR=0.876, 95% CI 0.824 to 0.932, P<0.001), artificial liver mode ( HR=0.819, 95% CI 0.236 to 0.992, P=0.005), spontaneous peritonitis ( HR=0.170, 95% CI 0.045 to 0.647, P=0.009) and hepatic encephalopathy ( HR=0.004, 95% CI 0.001 to 0.030, P<0.001) were independent influencing factors for 30-day survival outcome. The cumulative survival rate of sequential combination group was higher than that of conventional treatment group, and the difference was statistically significant ( χ2=5.45, P=0.020). There were no significant differences in the proportions of bleeding, deep vein thrombosis, heart rate and blood pressure instability between the two groups ( χ2=0.63, 1.20 and 0.54, respectively, all P>0.050). The platelet decline of patients in sequential combination group was slighter than that in conventional treatment group, and the difference was statistically significant ( t=-4.17, P=0.002). Conclusions:Multi-mode sequential combination therapy of artificial liver could eliminate cytokines and reduce MELD score more effectively in patients with HBV-ACLF, and prolong the survival time of patients and have little effect on platelet count.

ABSTRACT

Objective:To observe the differences in scleral lamina curvature (SLC) of patients with pseudoexfoliation glaucoma (PXG), primary open-angle glaucoma (POAG), and primary chronic angle-closure glaucoma (CPACG) were compared and analyzed and their significance was analyzed.Methods:A retrospective clinical study. From June 2017 to December 2020, 30 PXG (PXG group), POAG (POAG group) and CPACG patients (CPACG group) diagnosed at Eye Center of Cangnan County people's Hospital of Zhejiang Province (Cangnan Hospital Affiliated to Wenzhou Medical University) were included in the study. The age difference between the three groups of patients was statistically significant ( t=17.925, P=0.001); gender composition ratio ( χ2=2.158, P=0.276), intraocular pressure ( t=4.993, P=0.078), and axial length ( t=1.956, P=0.532), central corneal thickness ( t=1.407, P=0.724), average visual field defect ( t=2.725, P=0.496), optic disc retinal nerve fiber layer thickness ( t=2.185, P=0.492) in comparison, the differences were not statistically significant ( P>0.05). The frequency-domain optical coherence tomography deep-enhanced imaging (OCT EDI) technology was used to measure the average and 0°, 30°, 60°, 90°, 120°, 150° SLC of the affected eyes, and calculate the SLC index (SLCI) and SL curve depth (SLCD). Quantitative data comparison between groups used independent sample t test. Count data comparison used χ2 test. Univariate and multivariate logistic regression analysis were used for correlation analysis. Results:The results of OCT EDI examination showed that the SLC of eyes with PXG and CPACG was significantly steep, while the SLC of eyes with POAG was relatively flat. Except for the angle of 150°, the other 6 angles of SLCI and SLCD in the PXG group and CPACG group were higher than those in the POAG group, and the differences were statistically significant ( P<0.05). However, there was no statistically significant difference between PXG group and CPACG group for 7 angles of SLCI and SLCD ( P>0.05). Logistic regression analysis showed that the average SLCI [odds ratio (OR)=1.498, 95% confidence interval ( CI) 1.137-2.018, P=0.001], age ( OR=1.074, 95% CI 1.019-1.143, P=0.016) was significantly correlated with PXG; mean SLCI ( OR=1.625, 95% CI 1.192-1.997, P=0.001), intraocular pressure ( OR=1.383, 95% CI 1.106-1.993, P=0.012) was significantly correlated with CPACG. POAG group ( β=0.143, 95% CI 0.032- 0.208, P=0.016), CPACG group ( β=0.132, 95% CI 0.079-0.315, P=0.043) intraocular pressure was correlated with mean SLCI; all factors of PXG group were correlated with SLCI without correlation ( P>0.05). Conclusion:Compared with POAG, the SLC of eyes with PXG and CPACG is steeper and related to disease occurrence.

ABSTRACT

Objective:To analyze the relationship between antithrombin Ⅲ(AT-Ⅲ) activity and survival, bleeding and thrombosis complications in patients with acute-on-chronic liver failure (ACLF), and to explore the prediction value of AT-Ⅲ activity in the prognosis of ACLF patients.Methods:The clinical data of 130 hospitalized patients with ACLF were retrospectively collected in Wuxi No.5 People′s Hospital from January 1, 2013 to April 1, 2019. The liver function, international normalized ratio (INR), and 90-day survival rate were detected. The AT-Ⅲ activity values at admission, week two, week four, and week eight of hospitalization were recorded, and the occurrences of fecal occult blood and femoral vein thrombosis were also recorded. The measurement data were compared by t test, analysis of variance, or rank sum test, and the categorical data were compared by chi-square test. The risk factors affecting the survival of ACLF patients were analyzed by Cox regression. The survival analysis was performed using the Kaplan-Meier method. Results:At the end of 90-day follow-up of 130 patients, 56 patients died, 20 patients (15.38%) were fecal occult blood positive and 15 (11.54%) had femoral vein thrombosis. The baseline AT-Ⅲ activity in the death group was lower than that in the survival group ((17.89±13.68)% vs (36.03±11.96)%), and the difference was statistically significant ( t=-8.045, P<0.01). The baseline AT-Ⅲ activities in fecal occult blood positive and negative patients were (18.26±11.52)% and (25.06±10.97)%, respectively, and in femoral vein thrombosis and non-thrombotic patients were (17.55±10.33)% and (32.48±11.88)%, respectively. The differences were both statistically significant ( t=8.746 and 8.090, respectively, both P<0.01). Through dynamic monitoring of AT-Ⅲ, the AT-Ⅲ activity showed a downward trend in the death group, while that showed an upward trend in the survival group, but the differences were not statistically significant ( F=0.282 and 0.401, respectively, both P>0.05). The Cox regression analysis suggested INR (odds ratio ( OR)=1.364, 95% confidence interval ( CI) 1.078-1.726, P=0.010) and AT-Ⅲ activity ( OR=0.930, 95% CI 0.906-0.954, P<0.01) were the independent factors affecting the survival of patients with ACLF. The area under the receiver operator characteristic curve of the AT-Ⅲ activity for predicting 90-day survival outcome of the patient was 0.706 (95% CI 0.773-0.952, P<0.01), and the cut-off value was 25%. Patients with AT-Ⅲ activity ≥ 25% had a higher survival rate than those with AT-Ⅲ activity <25% ( χ2=58.20, P<0.01). Conclusions:AT-Ⅲ activity is associated with fecal occult blood positive and femoral vein thrombosis in ACLF patients. The AT-Ⅲ activity is an independent influencing factor for predicting the prognosis of ACLF patients. Patients with AT-Ⅲ activity less than 25% have the higher mortality rate.

ABSTRACT

Objective:To observe the effect of functional electrical stimulation (FES) combined with an ankle-foot orthosis (AFO) and gait training on lower limb motor function, gait parameters and the joint angles of hemiplegic stroke survivors.Methods:Thirty-two stroke survivors who met the inclusion criteria were selected and randomly divided into a control group ( n=10), an orthosis group ( n=10), and a combination therapy group ( n=12). In addition to routine medication and rehabilitation, the control group received only gait training, the orthosis group received gait training and an AFO and the combination therapy group was given FES, an AFO and gait training. All three groups were treated for four weeks. Then, the Fugl-Meyer lower extremity assessment (FMA-LE), the Brunnstrom lower extremity assessment (BRL), and Functional Ambulation Categories (FACs) were used to evaluate the lower limb motor function and walking ability of the three groups. The gait parameters of the three groups were quantified using a three-dimensional gait analyzer, and the changes in the hemiplegic gait before and after treatment were compared among the three groups. Results:After the treatment the average FMA-LE, FAC and BRL scores, time-space parameters, and joint angle parameters of all three groups had all improved significantly. After the intervention the average indicators in the combined therapy group (including stride frequency, stride length and walking speed) were all significantly better than in the other two groups.Conclusions:Adding FES to gait training with an AFO can effectively improve lower limb motor function and the walking ability of hemiplegic stroke survivors.

ABSTRACT

To evaluate the diagnosis and treatment of syndrome of inappropriate antidiuresis ( SIAD ) in multiple system atrophy ( MSA ) . Clinical features and treatment of a case of MSA with SIAD was retrospectively analyzed. An MSA-cerebellar predominant ( MSA-C) type patient was admitted for being fever. Pulmonary and urinary infections were identified. The patient was characterized by euvolaemic hyponatremia with reduced plasma osmolality and increased urine sodium. Hypothyroidism and hypoadrenalism were excluded via functional tests of different hormones. The diagnosis of SIAD was made. The fever and SIAD persisted after pulmonary and urinary infections were cured. The patient was sweatless and the body temperature varied with room temperature due to dysfunction of central thermoregulation. With fluid restriction, the serum sodium return to the lower limit of normal range. Though the SIAD in MSA is rare, water and sodium balance should be carefully maintained, especially for those with pulmonary infection.

ABSTRACT

Objective@#To explore the characteristics underlying Th1/Th2/Th17 expression level after entecavir (ETV) discontinuation of chronic hepatitis B (CHB) patients who were HBeAg-positive and define the role of Th1/Th2/Th17 in maintaining virological response after ETV discontinuation.@*Methods@#We selected 112 HBeAg positive CHB patients who met the withdrawal criteria according to the guideline of prevention and treatment of chronic hepatitis B (2010 version), and we also separated them into virology sustained response (SVR) group and virological relapse (VR) group according to the recurrence in 52 weeks. We detected serum level of Th1/Th2/h17 related cytokines during 0, 12, 24 and 52 weeks follow-up to further analyze their dynamic changes and expression differences.@*Results@#The results of the study reveals that serum levels of IFN-γ in the group of SVR were at a higher level compared with VR group during follow-up (all P<0.05). While, the serum level of IL-10 decreased in SVR group and was lower than the paired IL-10 level in VR group with significance during follow-up. In VR group, the serum level of IFN-γ decreased during the first 24 weeks after ETV withdrawal, and after then, the level rose. The serum levels of IFN-γ (Th1) in SVR patients were significantly higher than those in VR patients in the different follow-up time points after ETV discontinuation (all P<0.05). And the serum levels of IL-10 (Th2) in SVR patients were significantly lower than that in VR patients (all P<0.05). The comparison of serum levels of IL-17A (Th17) between the two groups had no significant difference (all P>0.005).@*Conclusions@#The serum level of IFN-γ in SVR group maintained a high level is conducive to maintaining virological response after ETV withdrawal and high level of IL-10 may be related to virologic relapse.

ABSTRACT

Objective To study the correlation between interleukin(IL)-21 and the recurrence of chronic hepatitis B(CHB)in hepatitis B e antigen(HBeAg)-positive patients after discontinuation of entecavir(ETV).Methods A total of 112 HBeAg-positive CHB patients treated with ETV were enrolled.Serum levels of IL-21 at week 0,12,24 and 52 after ETV discontinuation were detected.The Cox regression model was used to analyze the correlation between IL-21 and the recurrence after ETV discontinuation.The receiver operating characteristic(ROC)curve was applied to determine the predictive value of IL-21 for CHB recurrence after ETV discontinuation.The expression differences of IL-21 were compared between sustained viral response(SVR)group and viral relapse(VR)group.The t test and Chi-square test were used for statistical analysis.Results The serum levels of IL-21 in SVR group at week 0,12,24 and 52 after ETV withdrawal were(60.0 ± 10.8),(60.2 ± 14.7),(60.6 ± 19.5)and (61.2 ± 15.4)ng/L,respectively,which were all significantly higher than those in VR group(47.5 ± 10.7),(47.3 ± 12.9),(46.9 ± 12.2)and(46.4 ± 12.8)ng/L,respectively(t=6.153,4.926,4.382 and 5.515,respectively,all P< 0.01).The area under curve(AUC)was 0.811(95% CI:0.728 ~0.893,P<0.01)and the best cut-off value of serum IL-21 level was 49.8 ng/L.The recurrence rates of patients with serum IL-21 level ≥49.8 ng/L and <49.8 ng/L at time of ETV withdrawal was 25.4%(16/63)and 77.6%(38/49),respectively.The difference was statistically significant(χ2=30.027,P<0.01).The serum IL-21 level at the time of drug withdrawal(P= 0.005),serum hepatitis B surface antigen(HBsAg)level at the time of HBeAg seroconversion(P= 0.008)and age(P= 0.016)were factors associated with CHB recurrence after ETV withdrawal by multivariate Cox model analysis.The serum levels of ALT,HBV DNA,HBeAg and HBsAg in SVR group were significantly lower than those of VR group at week 12,24 and 52 after ETV withdrawal(t= -5.968,-7.691,-8.093; -3.047,-9.477,-28.900;-2.872,-10.424,-18.330;-4.633,-4.030 and -5.032,respectively;all P<0.01).Serum level of IL-21 was negatively correlated with HBsAg in SVR group after ETV withdrawal (r= -0.241,P<0.01),while positively correlated with HBsAg in VR group(r=0.286,P<0.01). Conclusions The serum IL-21 level at the time of drug withdrawal is associated with the recurrence after ETV discontinuation.IL-2l may play an important role as an immunomodulatory factor in maintaining virological responses in HBeAg-positive CHB patients after ETV withdrawal.

ABSTRACT

Objective To investigate the value of brain natriuretic peptide and heart failure ultrasound in the diagnosis of early chronic heart failure.Methods One hundred and forty-six patients with chronic heart failure and seventy-five healthy people with normal heart function were involved.According to NYHA classification,patients with chronic heart failure were divided into grade Ⅰ,Ⅱ,Ⅲ and Ⅳ,including grade Ⅰ twenty six,grade Ⅱ forty three,grade Ⅲ forty eight and grade Ⅳ twenty nine patients.Results There was no significant difference in the general information between patients with chronic heart failure and healthy people with normal heart function (P > 0.05),including age,sex,ALT,AST,fasting blood glucose,total cholesterol,triglyceride,serum creatinine and CRP.The BNP of the two groups were compared,and we found the BNP of grade Ⅱ (181.19 ±48.06),Ⅲ (279.26 ±49.45) and Ⅳ (882.34 ± 388.71) patients was significantly higher than healthy people (54.12 ± 25.87),and with the severity of heart failure,BNP increased gradually.There was statistically significant the difference (P < 0.05).but there was no significant difference between the patients of grade Ⅰ (77.14 ± 24.32) and healthy people (P > 0.05).Compared with healthy people(0.78 ± 0.42),HFEI was significantly higher in patients with chronic heart failure.The HFEI of grade Ⅰ (1.58 ± 0.89),Ⅱ (2.64 ± 1.07),Ⅲ (4.47 ± 1.39) and Ⅳ (6.33 ± 1.61) were compared,we found HFEI increased gradually with the severity of heart failure,and the difference was statistically significant (P < 0.05).From the analysis between BNP and HFEI,we found that BNP was significantly positively correlated with HFEI in patients with chronic heart failure (r =0.935,P =0.000).From ROC curve analysis,the area under the ROC curve of early chronic heart failure was 0.970,showing that plasma BNP combined with HFEI could be accurately diagnosed early chronic heart failure.Conclusion We find plasma brain natriuretic peptide and heart failure echocardiography index can be used in early diagnosis of chronic heart failure.

ABSTRACT

Objective To explore the sensitivity and specificity of colposcopy directed biopsy (CDB) and the value of loop electrosurgical excision procedure (LEEP) for the diagnosis and treatment of microinvasive cervical cancer (MCC). Methods One hundred and thirty five patients with MCC were diagnosed with LEEP in Obstetrics and Gynecology Hospital, Fudan University from April 2008 to November 2010, and were retrospectively analyzed on CDB diagnoses and following treatment after LEEP. According to patient′s desire for preservation of fertility and cone margin status, following strategies after LEEP included follow-up, second LEEP, hysterectomy, modified radical hysterectomy and radical hysterectomy. Single and multiple factors related to residual lesions after LEEP were analysed with Pearson Chi-square test and logistic regression model, respectively. Results CDB diagnosed MCC with a sensitivity of 4.4%(6/135), specificity of 100.0%(4 680/4 680), and false negative rate of 95.6%(129/135). Among the 135 patients, 29 did not receive further treatment in our hospital and lost contact. One hundred and six patients had secondary treatment or follow-up in our hospital, 4 of among which were closely followed up;one hundred and two received further treatment, which included 6 cases with second LEEP (3 received extrafascial hysterectomy after repeat LEEP), 59 cases hysterectomy, 14 cases modified radical hysterectomy and 26 cases radical hysterectomy. For factors related to residual lesions after LEEP, single factor analysis showed that the ratio of residual lesion in patients aged 27-39, 40-49 and 50-65 years were respectively 19.0%(11/58), 15.4%(10/65) and 5/12 (χ2=4.505, P=0.105). Residual lesions occurred in 24.7%(23/93) of patients with positive LEEP margins, which was more than that 7.1%(3/42) of patients with negative LEEP margins (χ2=5.756, P=0.016). The ratio of residual lesions in patients with positive endocervical, ectocervical and deep stromal margins were respectively 29.6%(8/27), 17.1%(7/41)and 30.6%(11/36;χ2=2.275, P=0.321). Residual lesions in patients with or without lymph vascular space invasion (LVSI) were 2/7 and 18.8%(24/128), respectively (χ2=0.412, P=0.521). The ratio of residual lesions in patients with invasion depth of<1 mm was 17.1%(7/41), 1-<3 mm was 19.0%(16/84), and 3-5 mm was 3/10, with no significant difference among three groups (χ2=0.870, P=0.647). Logistic regression analysis showed positive cone margin (OR=5.069, P=0.014) and age (OR=1.080, P=0.024) were the independent risk factors of residual lesions after LEEP conization. Conclusions CDB alone is not adequate for the diagnosis of MCC. For young patients who desire to preserve fertility with a negative cone margin, close follow-up is acceptable. Cone margin status and age are two independent risk factors for residual lesions after LEEP.

ABSTRACT

In the face of escalating problems with pathogen control, the development of proper formulations of existing antibiotics is as important as the development of novel antibiotics. Daptomycin is a lipopeptide antibiotic with potent activity against Gram-positive bacteria. Currently, only injectable solution of daptomycin has been approved for clinical use. In the present study, the formulation of PEGylated liposomal daptomycin (PLD) was prepared and optimized, and its efficacy against methicillin-resistant Staphylococcus aureus (MRSA252) strains was investigated. The obtained PLD had a mean vesicle diameter of (111.5 +/- 15.4) nm and a mean percent drug loading of (5.81 +/- 0.19) % with high storage stability. Potent activity of PLD against MRSA was demonstrated in vitro with a more sustained effect than that of conventional liposomal daptomycin and daptomycin solution. In addition, intravenous administration of a single dose (equal to human use) of PLD significantly increased the survival of mice in a MRSA252 systemic infection model compared with other formulations. Drug distribution in the lung was significantly enhanced following administration of PLD, and no measurable tissue lesions or pathological changes were detected during PLD treatment. Taken together, PEGylated liposomes loaded with daptomycin may represent a promising approach to reduce MRSA252 infections, especially those involving bloodstream dissemination, such as hematogenous pulmonary infection.

ABSTRACT

In this study, we developed a novel liposome-silica hybrid nano-carrier for tumor combination therapy via oral route, using paclitaxel and cyclosporine as a model drug pair. Optimization of the preparation of the drug-loading formulation and characterization of its physicochemical parameters and drug release profile were performed in vitro. Then in vivo pharmacodynamics and pharmacokinetics studies were performed. The results showed that the obtained formulation has a small particle size (mean diameter of 100.2 +/- 15.2 nm), a homogeneous distribution [the polydispersity index was (0.251 +/- 0.018)] and high encapsulation efficiency (90.15 +/- 2.47) % and (80.64 +/- 3.52) % for paclitaxel and cyclosporine respectively with a mild and easy preparation process. A sequential drug release trend of cyclosporine prior to palictaxel was observed. The liposome-silica hybrid nano-carrier showed good biocompatibility in vivo and co-delivery of cyclosporine and paclitaxel significantly enhanced the oral absorption of paclitaxel with improved anti-tumor efficacy, suggesting a promising approach for multi-drug therapy against tumor and other serious diseases via oral route.

ABSTRACT

The aim of this study is to investigate the feasibility of silica-coated ethosome as a novel oral delivery system for the poorly water-soluble curcumin (as a model drug). The silica-coated ethosomes loading curcumin (CU-SE) were prepared by alcohol injection method with homogenization, followed by the precipitation of silica by sol-gel process. The physical and chemical features of CU-SEs, and curcumin release were determined in vitro. The pharmacodynamics and bioavailability measurements were sequentially performed. The mean diameter of CU-SE was (478.5 +/- 80.3) nm and the polydispersity index was 0.285 +/- 0.042, while the mean value of apparent drug entrapment efficiency was 80.77%. In vitro assays demonstrated that CU-SEs were significantly stable with improved release properties when compared with curcumin-loaded ethosomes (CU-ETs) without silica-coatings. The bioavailability of CU-SEs and CU-ETs was 11.86- and 5.25-fold higher, respectively, than that of curcumin suspensions (CU-SUs) in in vivo assays. The silica coatings significantly promoted the stability of ethosomes and CU-SEs exhibited 2.26-fold increase in bioavailablity relative to CU-ETs, indicating that the silica-coated ethosomes might be a potential approach for oral delivery of poorly water-soluble drugs especially the active ingredients of traditional Chinese medicine with improved bioavailability.
