RESUMEN
<p><b>OBJECTIVE</b>To explore the effect of compound qizhu granule (CQG) on cellular immunity of chronic hepatitis B (CHB) patients.</p><p><b>METHODS</b>Totally 103 CHB patients treated with lamivudin (LAM) for 6 months, who had partial virological response (HBeAg positive) were randomly assigned to two groups, 50 in the treatment group and 53 in the control group. All patients took LAM 100 mg (once a day) plus ADV 10 mg (once a day). Patients in the treatment group additionally took CQG, one dose per day. After one-year treatment hepatitis B virus (HBV) DNA negative rates, HBeAg seroconversion, levels of HBV specific cytotoxic T lymphocyte (CTL), non-specific CTL and natural killing (NK) cells were compared between the two groups.</p><p><b>RESULTS</b>After 1-year treatment, HBV DNA negative rate of the treatment group was 88: 0% in 44 cases, slightly higher than that of the control group (41 cases, 77.4%), but with no statistical difference (P >0.05). HBeAg seroconversion of the treatment group was 32.0% in 16 cases, higher than that of the control group (8 cases, 15.1%), with statistical difference (P <0.05). Levels of HBV specific CTL (0.79%±0. 07%), non-specific CTL (19.4%±1.8%) and NK cells (14. 1%± 1.5%) of the treatment group were higher than those of the control group (0.58% ± 0.08%, 17.5% ± 1.7%, and 11.1%±1.5%, respectively; allP <0.01).</p><p><b>CONCLUSION</b>Treating CHB patients with partial virological response by ADV plus CQG could improve specific and non-specific cellular immunity, thereby elevating HBeAg seroconversion rate.</p>

<p><b>OBJECTIVE</b>To explore relationship between HBV DNA level and peripheral blood follicular helper T lymphocyte (Tfh) in patients with chronic hepatitis B (CHB) and its significance.</p><p><b>METHODS</b>HBV DNA levels of 179 cases of CHB patients with positive HBV DNA, positive HBeAg and positive human leukocyte antigen(HLA)-A2 were tested with real time fluorescent quantitative PCR. Tfh and HBV specific CTL were tested with flow cytometry. IL-21 was also tested. 179 cases of CHB patients were divided into group A and group B based on HBV DNA levels, 86 cases in group A, HBV DNA levels were 10(4)-10(5) copies/ml, 93 cases in group B, HBV DNA levels were 10(6)-10(7) copies/ml. Above testing indexes of the two groups were compared.</p><p><b>RESULTS</b>HBV DNA levels of group A were (4.85 +/- 0.37) log10 copies/ml, HBV DNA levels of group B were (6.83 +/- 0.31 ) log10 copies/ml, t = 27.31, P < 0. 001; Tfh of group A was (5.96 +/- 1.59)%, higher than that of group B (3.71 +/- 2.15)%, t = 4.92, P < 0.01; IL-21 of group A was (42.61 +/- 15.11)ng/L, higher than that of group B (14.91 +/- 3.15) ng/L, t = 8.62, P < 0.01; HBV specific CTL of group A was (0.36 +/- 0.08)%, higher than that of group B (0.18 +/- 0.06)%, t = 19.99, P < 0.001.</p><p><b>CONCLUSION</b>Serum HBV DNA level of CHB patients is related to the level of peripheral blood Tfh level: patients with low HBV DNA level have high Tfh level, high IL-21 level and high HBV specific CTL level. Patients with high HBV DNA level have low Tfh level, low IL-21 level and low HBV specific CTL level. The mechanism of baseline HBV DNA level affecting anti-viral therapy may be related to Tfh level.</p>

<p><b>OBJECTIVE</b>To explore influence of sodium restricted diet and non-sodium restricted diet on plasma rennin (PRA), angiotensin II (All), ALD, renal blood flow (RBF) and subside of ascites in patients with cirrhotic ascites.</p><p><b>METHODS</b>Eighty cases of hepatitis B with cirrhotic ascites were randomly divided into sodium restricted diet group and non-sodium restricted diet group. 39 cases were in non-sodium restricted diet group, taking sodium chloride 6500-8000 mg daily; 41 cases were in sodium restricted diet group, taking sodium chloride 5000 mg daily. Both groups received diuretics furosemide and spironolactone. Blood sodium, urine sodium, PRA, AII, ALD, RBF ascites subsiding were compared after treatment.</p><p><b>RESULTS</b>In non-sodium restricted diet group, blood sodium and urine sodium increased 10 days after treatment compared with those before treatment, and compared with those of sodium restricted diet group 10 days after treatment, P <0. 01. RBF increased compared with that before treatment, and compared with that of sodium restricted diet group 10 days after treatment, P < 0. 01. Renal damage induced by low blood sodium after treatment was less in non-sodium restricted diet group than that in sodium restricted diet group, P <0. 05. Ascites disappearance upon discharge was more in sodium restricted diet group than that in non-sodium restricted diet group, P <0. 01. Time of ascites disappearance was shorter in non-sodium restricted diet group than that in sodium restricted diet group, P < 0. 01.</p><p><b>CONCLUSION</b>Compared with sodium restricted diet, while using diuretics of both groups, non-sodium restricted diet can increase level of blood sodium, thus increasing excretion of urine sodium and diuretic effect. It can also decrease levels of PRA, AII and ALD, increase renal blood flow and prevent renal damage induced by low blood sodium and facilitate subsiding of ascites.</p>

BACKGROUND/AIMS: There has been debate on whether a sodium-restricted diet (SRD) should be used in cirrhotic patients with ascites in China in recent years. The purpose of this study was to compare the effect of sodium-restricted and unrestricted diets on plasma renin activity (PRA), renal blood flow (RBF) and ascites in patients with liver cirrhosis. METHODS: Two hundred cirrhotic patients with ascites were randomly divided into two groups (98 cases in the sodium-unrestricted diet [SUD] group and 102 cases in the SRD group); 95 patients (96.94%) in the SUD group and 97 patients (95.1%) in the SRD group had post-hepatitis B cirrhosis. RESULTS: Blood sodium and RBF were higher in SUD group than in SRD group (p<0.001), while PRA were significantly lower in SUD group than the SRD group 10 days after treatment (p<0.001). Renal impairment caused by low blood sodium was higher in SRD group than in SUD group (p<0.01). Ascites disappeared in higher proportion of patients in SUD group than in SRD group (p<0.001). CONCLUSIONS: SUD can increase the level of blood sodium and RBF, and be beneficial to diuresis and ascite reduction and disappearance.

<p><b>BACKGROUND</b>Oxymatrine has certain antiviral effects in the treatment of chronic hepatitis B (CHB), but its exact mechanism is unclear. The objective of the present study was to explore oxymatrine's antiviral mechanism by studying its effect on the hepatitis B virus (HBV) specific cytotoxic T lymphocyte (CTL) surface programmed death receptor-1 (PD-1) expression in CHB patients.</p><p><b>METHODS</b>Sixty-five CHB patients who had HBV DNA(3)10(4) copies/ml, positive HBeAg, positive human leukocyte antigen (HLA)-A2, alanine aminotransferase (ALT) > 2 x upper limit of normal value (ULN) were randomly divided into two groups: treatment group (n = 33), treated with an intravenous infusion of 600 mg oxymatrine in glucose solution once a day for a month, then with a 200 mg oxymatrine oral capsule three times a day, and a 200 mg silibin meglumine tablet three times a day; control group (n = 32) patients were treated only with silibin meglumine tablet, method and dosage were the same as those of treatment group. Three months later, peripheral blood HBV-specific CTL surface PD-1 expression, HBV-specific CTL level, HBV DNA, HBeAg, and results of liver function tests were analyzed and compared.</p><p><b>RESULTS</b>Three months post-treatment, in the treatment group, peripheral blood HBV-specific CTL surface PD-1 expression ((19.42 ± 15.94)%) decreased significantly compared to the pretreatment level ((31.30 ± 24.06)%; P < 0.05), and decreased significantly compared to that of control group three months after treatment ((29.45 ± 21.62)%; P < 0.05). HBV-specific CTL level ((0.42 ± 0.07)%) significantly increased compared with the pretreatment ((0.29 ± 0.15)%; P < 0.01), and the control group posttreatment level was (0.31 ± 0.15)% (P < 0.05). HBV DNA level in 11 cases became negative (HBV DNA < 500 copies/ml, 33.33%), which was higher than that of the control group after treatment (two cases, 6.25%; χ(2) = 7.45, P < 0.01), HBeAg of nine cases turned negative (27.27%), which was higher than that of the control group after treatment (one case, 3.13%; χ(2) = 7.27, P < 0.01).</p><p><b>CONCLUSION</b>Oxymatrine could downregulate peripheral blood HBV-specific CTL surface PD-1 expression in CHB patients, increase HBV-specific CTL level, which may be one of the possible mechanisms by which oxymatrine clears or inhibits HBV in CHB patients.</p>

<p><b>BACKGROUND</b>Medical ozone therapy system was reported to have certain effects on the treatment of severe hepatitis, but its mechanism is not very clear. One of the causes of death of severe hepatitis is complication of renal damage or hepatorenal syndrome. The present study aimed to observe effects of medical ozone therapy system on plasma renin activity (PRA), angiotensin II (AII), aldosterone (ALD), renal blood flow and renal function of patients with chronic severe hepatitis and explore mechanisms of medical ozone therapy in the treatment of severe hepatitis.</p><p><b>METHODS</b>Eighty-five cases with chronic severe hepatitis were randomly divided into ozone therapy group (43 cases) and control group (42 cases). The patients in the ozone therapy group were treated with basic treatments plus ozone therapy system. Basic autohemotherapy was used. One hundred milliliter venous blood was drawn from each patient, and was mixed with 100 ml (35 µg/ml) medical ozone and then was returned the blood to the patient intravenously, once every other day for 20 days. Only the basic treatments were given to the control group. PRA, AII, ALD, renal blood flow and damage to renal function of the two groups before treatment and 20 days after treatment were compared. Survival rates were also compared.</p><p><b>RESULTS</b>Twenty days after the treatment, in ozone therapy group, PRA was (1.31 ± 0.12) ng·ml⁻¹·h⁻¹, AII (111.25 ± 17.35) pg/ml, ALD (251.31 ± 22.60) pg/ml, which decreased significantly compared with those before treatment (PRA (2.23 ± 0.13) ng·ml⁻¹·h⁻¹, AII (155.18 ± 19.13) pg/ml, ALD (405.31 ± 29.88) pg/ml, t = 4.67 - 14.23, P < 0.01), also lower than those of control group 20 days after the treatment (PRA (2.02 ± 0.11) ng·ml⁻¹·h⁻¹, AII (162.21 ± 15.32) pg/ml, ALD (401.20 ± 35.02) pg/ml, t = 4.97 - 15.61, P < 0.01); renal blood flow was (175.15 ± 28.20) ml/min, which increased compared with that before the treatment ((125.68 ± 21.25) ml/min) and was higher than that of control group 20 days after the treatment ((128.59 ± 23.15) ml/min, t = 4.78, 4.61, P < 0.01). Renal damage occurred in 2 cases (5%) in ozone therapy group, less than that in control group (9 cases, 21%) (χ² = 5.295, P < 0.05). Thirty-three cases (77%) in ozone therapy group vs. 16 cases (38%) in control group survived (χ² = 12.993, P < 0.01).</p><p><b>CONCLUSIONS</b>Basic treatment plus medical ozone therapy for patients with chronic severe hepatitis could decrease PRA, AII and ALD levels significantly increase renal blood flow, prevent renal damage to certain extent and improve survival rate of the patients.</p>

<p><b>OBJECTIVE</b>To explore the association of serum HBV DNA level with HBV-specific and nonspecific cytotoxic T lymphocytes (CTL) in patients with HBV-induced hepatic cirrhosis.</p><p><b>METHODS</b>120 patients with HBV-induced hepatic cirrhosis who were positive for HBV DNA, HBeAg and human leucocyte antigen (HLA)-A2 were enrolled in this study. The level of HBV DNA was determined by real time fluorescence quantitative polymerase chain reaction (PCR). HBV-specific and nonspecific CTL were detected by flow cytometry. Liver function tests were done in the 120 patients. The 120 patients were divided into group A and B based on their HBV DNA levels. In group A, there were 68 patients with HBV DNA level of 3-4 log10 copy/ml, and in group B, 52 with 5-6 log10 copy/ml. HBV-specific and nonspecific CTL and liver function were compared between the two groups.</p><p><b>RESULTS</b>HBV DNA levels were (3.68 +/- 0.19) and (5.97 +/- 0.32) log10 copy/ml in Group A and B respectively with P < 0.001. HBV-specific CTL was higher in group A (0.33% +/- 0.04%) than in group B (0.11% +/- 0.01%) with P < 0.001. HBV-nonspecific CTL were (11.99% +/- 1.51% ) and (11.91% +/- 1.61%) in group A and B respectively with P > 0. 05.</p><p><b>CONCLUSION</b>The level of serum HBV DNA is related to the levels of HBV-specific CTL in patients with HBV-induced hepatic cirrhosis. Patients with higher HBV DNA had lower levels of HBV-specific CTL, and the damage to liver function was severe because of higher levels of HBV DNA.

<p><b>BACKGROUND</b>The response of patients with chronic hepatitis B (CHB) to antiviral therapy against hepatitis B virus (HBV) is related to the base line level of HBV DNA, but the mechanism is not clear. The present study aimed to understand the possible relationship between the level of HBV DNA and HBV-specific, nonspecific cytotoxic T lymphocytes (CTL) and natural killer (NK) cells of CHB patients and the mechanism how the HBV DNA level influences the antiviral therapeutic effect.</p><p><b>METHODS</b>Totally 100 adult patients with CHB who were positive for HBV DNA, HBeAg and (HLA)-A2 were enrolled into this study. HBV DNA was tested by real time fluorescence quantitative polymerase chain reaction (PCR). HBV specific and nonspecific CTL and NK cells were tested by flowcytometry. Serum alanine aminotransferase (ALT) and total bilirubin (TBil) were determined for each patient using routine biochemical tests. The 100 cases were assigned to two groups based on their HBV DNA level: group A had 48 cases, their HBV DNA level was 10(4) - 10(5) copies/ml, group B had 52 cases, their HBV DNA level was 10(6) - 10(7) copies/ml. HBV specific CTL, nonspecific CTL, NK cells, ALT and TBil of the two groups were compared.</p><p><b>RESULTS</b>HBV DNA level of groups A and B was (4.81 +/- 0.39) log(10) copies/ml and (6.81 +/- 0.40) log(10) copies/ml, respectively (t = 25.32, P < 0.001). HBV specific CTL and NK cells of group A were significantly higher than those of group B (P < 0.001 for both). Nonspecific CTL of group A was significantly lower than that of group B (P < 0.01). ALT and TBil of group A were significantly lower than those of group B (P < 0.01 and P < 0.05, respectively).</p><p><b>CONCLUSIONS</b>Serum HBV DNA level of patients with CHB is related to HBV specific CTL, nonspecific CTL and NK cells, which might result in inflammatory reaction of liver and cause more damage to liver function. Mechanism of HBV DNA level affecting the efficacy of anti-viral treatment may be related to the levels of HBV specific CTL and NK cells.</p>

<p><b>OBJECTIVE</b>To explore influence of Kurarinol on specific and non-specific cell immunity in patients with chronic hepatitis B.</p><p><b>METHODS</b>74 cases of CHB were randomly divided into two groups, 36 cases in treatment group, treated with 600 mg Kurarinol glucose injection, IV, once a day. After one month, Kurarinol capsule was used orally, three times a day for 2 months, 200 mg Silybin Meglumine Tablets orally, three times a day for 3 months. 38 cases in control group, only Silybin Meglumine Tablets was used, method and dosage were the same as treatment group. Compare HBV specific CTL, non-specific CTL, sub-group of T cells, changes of Th1 and Th2, negative conversion rate of HBV DNA and HBeAg of the two groups.</p><p><b>RESULTS</b>In treatment group, 3 months after treatment with Kurarinol, HBV specific CTL is higher than that before treatment (P < 0.01), it is also higher than that of control after treatment, P < 0.05) . Non-specific CTL is higher than that before treatment (P < 0.05), it is also higher than that of control after treatment (P < 0.01). CD4 is higher than that before treatment (P <0.05), it is also higher than that of control after treatment (P < 0.01), Thl is higher than that before treatment (P < 0.05), it is also higher than that of control after treatment (P < 0.01) . Negative conversion of HBV DNA and HBeAg is higher than that of control (P < 0.01).</p><p><b>CONCLUSION</b>Kurarinol can improve specific and non-specific cell immunity in patients with CHB. It is one of the mechanisms that Kurarinol can clear or inhibit HBV of patients with CHB.</p>
