Objective To evaluate urinary β2-microglobulin (β2-MG) and retinoid binging protein (RBP) in monitoring of early renal impairment in chronic hepatitis B (CHB) patients with long-term adefovir dipivoxil (ADV) treatment. Methods Three hundred and fifty five with CHB admitted in Shaoxing Municipal Hospital from June 2009 to June 2011 were enrolled in the study, among whom 180 cases study group) were treated with ADV monotherapy (n=100) or ADV + lamivudine (LAM) combination therapy (n=80); and 175 cases (control group) were treated with entecavir (ETV). Serum creatinine, urinary β2-MG, RBP and creatinine were measured and glomerular tration rate (eGFR) was estimated regularly during 5-year follow up. Kaplan-Meier method was used to calculate the cumulative incidence of changes in urinary β2-MG and RBP. Results Five-year follow-up results showed that in study group 2, 6, 10, 14 and 24 cases developed urinary β2-MG abnormality in year 1, 2, 3, 4 and 5 of treatment, respectively; and 2, 7, 11, 16 and 20 cases developed urinary RBP abnormality in year 1, 2, 3, 4 and 5 of treatment, respectively; eGFR decreased 20%-30% from baseline in 20 cases, 30%-50% in 13 cases and >50% in 2 cases. The decrease of eGFR ≥30% in 5 years was significantly correlated with urinary RBP and β2-GM abnormality. However, both serum creatinine and eGFR remained stable during the 5 years of follow-up in control group; only 2 cases developed urinary β2-MG abnormality and 3 cases developed urinary RBP abnormality. Conclusions Urinary RBP and β2-MG are sensitive biomarkers of early renal injury during long-term ADV treatment in CHB patients, and ADV should not be used as first-line treatment for CHB.

Objective:To evaluate the value of neutrophil to lymphocyte and platelet ratio (N/LPR) for predicting 28-day mortality in sepsis patients.Methods:A retrospective analysis was conducted. The clinical data of 154 sepsis patients admitted to intensive care unit (ICU) of the Affiliated Hospital of Jiangsu University from June 2017 to June 2020 were enrolled. The time of first diagnosis of sepsis in ICU was taken as the research starting point, and the death or 28 days as the end point. The 28-day outcomes of patients were recorded. The counts of peripheral blood neutrophil (NEU), lymphocyte (LYM) and platelet (PLT) were collected from all the enrolled patients within 3 days after diagnosis of sepsis. The ratios of N/LPR and NEU/LYM (NLR) were calculated respectively. The differences of N/LPR and NLR between survival group and death group were compared. Receiver operating characteristic (ROC) curve analysis was used to analyze the value of N/LPR and NLR on predicting the 28-day mortality of sepsis patients. According to the best cut-off value of ROC curve analysis, the 28-day mortality of patients with sepsis was analyzed by subgroup analysis, and the 28-day cumulative survival of patients with sepsis was analyzed by Kaplan-Meier survival curve.Results:Of the 154 sepsis patients, the patients with age < 18 years, pregnancy, blood disease, taking aspirin or other antiplatelet drugs within 1 week, taking leucocyte drugs within 1 week, length of ICU stay < 3 days and incomplete data were excluded. Finally, 50 patients were enrolled. Among them, 30 patients survived on the 28th day and 20 died. Compared with the survival group, the levels of N/LPR and NLR in the death group were significantly increased (N/LPR: 23.85±11.99 vs. 12.41±5.25, NLR: 17.83±8.69 vs. 10.75±3.63), with statistical differences (both P < 0.01). ROC curve analysis indicated that the area under ROC curve (AUC) of N/LPR for predicting 28-day death of sepsis patients was 0.827, it was higher than that of NLR (AUC = 0.762). Base on N/LPR≥15.48 as a predictor of cut-off value of death in 28 days of sepsis patients, the sensitivity was 75.0% and the specificity was 80.0%, respectively. Base on NLR≥10.65 as a predictor of cut-off value of death in 28 days of sepsis patients, the sensitivity was 75.0% and specificity was 56.7%, respectively. Subgroup analysis showed that the 28-day mortality in the patients with N/LPR≥15.48 ( n = 21) was significantly higher than those with N/LPR < 15.48 ( n = 29; 71.4% vs. 17.2%, χ 2 = 14.901, P < 0.01); and the 28-day mortality in the patients with NLR≥10.65 ( n = 28) was also significantly higher than those with NLR < 10.65 ( n = 22; 53.6% vs. 22.7%, χ 2 = 4.884, P < 0.05). The results were consistent with Kaplan-Meier survival curve analysis. Conclusion:Peripheral blood N/LPR has a good predictive value for 28-day mortality of sepsis patients, and which is better than NLR.

Objective To compare the impact of Telbivudine (LDT) and Entecavir (ETV) administration on estimates of glomerular filtration rate for anti-viral therapy in patients with hepatitis B virus (HBV)-related compensated cirrhosis by an open, prospective randomized controlled study.Methods Patients with HBV-related compensated cirrhosis at clinic or hospitalized in Shaoxing Municipal Hospital from January 2012 to June 2013 were included.A total of 170 patients were randomly divided into LDT (600 mg/d) or ETV (0.5 mg/d) groups at a ratio of 1∶1 according to the random number table method.All patients were treated for more than 36 months.The LDT group was optimized according to the roadmap.Patients with poor response or resistance in both treatment group were added with Adefovir dipivoxil (ADV) 10 mg/d for optimal treatment.The clinical outcome, creatinine (CR), estimated glomerular filtration rate (eGFR) of patients before and after 36 months of treatment were compared between two groups.All categorical data were analyzed using chi-square test and data accorded with normal distribution were compared by t test.Results After 36 months of treatment, the virological and biochemical responses in LDT group and ETV group were similar.The mean CR levels at month 24 and 36 in LDT group were (74.25±22.98) μmol/L and (70.72±24.75) μmol/L, respectively, which were both lower than baseline level ([83.09±17.68] μmol/L, t=2.811 and 3.145, respectively, both P<0.01).The mean CR levels at month 36 between two groups were statistically different (t=3.431, P=0.001).The mean eGFR levels at month 12, 24 and 36 in LDT group were all significantly lower than that at baseline (t=3.976,8.297 and 10.629, respectively, all P<0.01).The mean eGFR levels at month 24 and 36 between two groups were statistically different (t=9.684 and 15.019, respectively, both P<0.01).A total of 64 patients including 34 in LDT group and 30 in ETV group had mild nephritic injury at baseline.The mean eGFR in patients with mild nephritic injury at baseline in LDT group at month 12, 24 and 36 were significantly different compared to baseline (t=6.098,10.191 and 14.378, respectively, all P<0.01).The mean eGFR level at month 36 in ETV group had statistical difference compared to baseline (t=2.058, P<0.05).The mean eGFR levels at months 12, 24 and 36 were all statistical different between two groups (all P<0.01).The mean eGFR levels at month 24 and 36 in the optimized group were superior to ETV group (P<0.01).Conclusions In patients with HBV-related compensated cirrhosis, LDT and ETV treatment have similar clinical efficacy.LDT is more effective in protecting nephritic function than ETV.

Objective To investigate the effect of coupled plasma filtration adsorption (CPFA) on plasma cytokines:TNF-α,IL-1β,IL-6,cellular immunity,blood lactate acid concentration,heart rate,respiration rate,oxygenation index,hemodynamics,blood cells counts,and prognosis in patients with multiple organ dysfunction syndromes (MODS).Methods This was a prospective,randomized clinical trial in 45 patients diagnosed as MODS.Patients were randomly assigned to hemoperfution with resin adsorption (HP) + continuous venous-venous hemofiltration (CVVH) group,CPFA group and CVVH group.The general clinical data,APACHE Ⅱ score,number of failure organ and previous mentioned biomarkers were documented.Blood samples were collected before and after blood filtration with any one of these procedures.The plasma samples were isolated and stored with frozen at-60 ℃.Data were statistically analyzed with SPSS 13.0 version software.Results In CPFA group,plasma cytokines,TNF-α、IL-1β、IL-6,decreased markedly after plasma adsorption for two hours (P ＜ 0.01);and plasma concentrations of IL-6 were further descended after subsequent CVVH for 10 hours (P ＜ 0.05).In HP + CVVH group,plasma cytokines,TNF-α、IL-1β、IL-6,decreased markedly after HP (P ＜ 0.01),and plasma concentrations of IL-6 were further descended after subsequent CVVH for 10 hours (P ＜ 0.05).In CVVH group,plasma cytokines,TNF-α、IL-1β、IL-6,decreased after CVVH for 12 hours (P ＜ O.05).Blood lactate acid concentration,heart rate,respiration rate,oxygenation index,T-lymphocytes subgroups (CD3 +,CD4 +,CD8 +,CD4 +/CD8 + ratio),clinical symptoms were improved and dose of vasoactive agent was reduced in the patients of three groups without differences among them.The counts of red blood cells,white blood cells and platelets after CPFA and CVVH showed no significant changes.There was no significant difference in blood cell counts between CPFA and CVVH groups.After HP + CVVH,there was a trend of decrease in platelet count (P ＜ 0.05).Platelet counts were significanfly higher in patients treated with CPFA and CVVH group than those in patients treated with HP + CVVH group (P ＜ 0.05).There were 6 patients died in HP + CVVH group,6 patients died in CPFA group and 5 patients died in CVVH group within 28days.Conclusions The comparison of efficacy of blood filtration among 3 modalities of HP + CVVH,CPFA and CVVH showed CPFA had higher capacity of Inflammatory medium scavenging than CVVH,and had less damage effect on blood visible component,especially on platelet compared with HP + CVVH.CPFA was an effective and safety modality in the treatment of the patients with multiple organ dysfunction syndrome.

Objective To study the effect of Shenfukang Ⅱ on kidney function and TGF-β1/Smads signal pathway with 5/6 nephrectomy model in rats. Methods Thirty SD rats were randomly divided into the sham operation group, model group and Shenfukang group according to a random number table. We used 5/6 nephrectomy to prepare animal models. The rats were given Shenfukang Ⅱ particles 450 mg/(kg?d) gavage, the others group were given equal volume of saline gavage, once a day, continuous 21 days. The rats were given gavage at the 9 th week after operation. The changes of renal function index BUN, SCR and UA of rats in each group were detected 21 days after administration. The expression of TGF-β1, TGFβR1, Smad7, pSmad2, pSmad3 in renal tissues were detected by immunohistochemistry. The Smad7, pSmad2 and pSmad3 detected the expression of in renal tissues by Western Blot. Results Compared with the model group, the content of BUN (15.03 ± 2.19 mmol/L vs. 24.30 ± 2.82 mmol/L), SCR (74.22 ± 7.36 μmol/L vs. 93.61 ± 14.73 μmol/L) in Shenfukang group significantly decreased (P<0.05). The expression of TGF-β1, TGFβR1, pSmad2 and pSmad3 significantly decreased in kidney tissue, while the expression of Smad7 significantly increased in kidney tissue. The expression of p-smad2 (0.47 ± 0.03 vs. 0.64 ± 0.04) and p-smad3 (0.43 ± 0.04 vs. 0.55 ± 0.02) significantly decreased (P<0.05), and the expression of Smad7 (0.54 ± 0.03 vs. 0.39 ± 0.02) significantly increased (P<0.05). Conclusions Shenfukang Ⅱ have improved on kidney function with 5/6 nephrectomy model rats. The study revealed that Shenfukang II may play an anti-fibrotic effect on regulating TGF-β1/Smads signaling pathway with 5/6 nephrectomies model.
