OBJECTIVE: To investigate the effect of relaxing needling at the contracted sites of meridian-muscle regions in the patients with post-stroke shoulder-hand syndrome (SHS) at acute stage. METHODS: Eighty patients with post-stroke SHS at acute stage were randomized into an observation group (40 cases, 1 case dropped out) and a control group (40 cases, 1 case was eliminated). In the control group, the routine medication, basic rehabilitation training, and hyperbaric oxygen therapy were administered. In the observation group, besides the treatment as the control group, relaxing needling was delivered at the contracted sites of meridian-muscle regions. These contracted sites were distributed along three yin meridians of hand and three yang meridians of hand on the affected upper limbs. The intervention was given once daily, 5 times a week and for 4 weeks. Before and after treatment, the scores of visual analogue scale (VAS) for pain, edema degree, modified Barthel index (MBI), and Fugl-Meyer assessment (FMA) for motor function, and the integrated electromyography (iEMG) of surface electromyogram (sEMG) were observed in the two groups. The curative effect was evaluated after treatment and in follow-up of 2 months after treatment in the two groups. RESULTS: After treatment, VAS scores and the scores of edema degree were reduced when compared with those before treatment in the two groups (P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). MBI and FMA scores increased after treatment compared with those before treatment in the two groups (P<0.05), and the scores in the observation group were higher than those in the control group (P<0.05) after treatment. The iEMG values of the biceps brachii, triceps brachii, and wrist extensors were elevated after treatment in comparison with those before treatment (P<0.05) in the two groups, and the values in the observation group were larger than those in the control group after treatment (P<0.05). The total clinical effective rate in the observation group was 92.3% (36/39), which was better than that of the control group (74.4%, 29/39, P<0.05) after treatment; and that of the observation group was 97.4% (38/39), which was better than 82.1% (32/39) in the control group (P<0.05) in follow-up. CONCLUSION Relaxing needling at the contracted sites of meridian-muscle regions in treatment of post-stroke SHS at acute stage can attenuate the symptoms such as upper limb pain, swelling and spasm, improve motor function and the activity of daily living of patients.

Background and aim:Few studies have reported hepatitis B surface antigen(HBsAg)kinetics after nucleos(t)ide analog(NA)discontinuation in patients with noncirrhotic chronic hepatitis B(CHB).The study specifically investigated long-term HBsAg kinetics after NA discontinuation. Methods:Between January 2014 to January 2024,this study prospectively enrolled 106 outpatients with noncirrhotic CHB who met the discontinuation criteria after NA consolidation treatment.Demographic,clinical,and laboratory data were collected and analyzed after NA discontinuation. Results:Ninety-six patients who finished 5 years of follow-up were included.HBsAg remained unde-tectable in 29 patients with end of treatment(EOT)HBsAg negativity.Among 67 patients with EOT HBsAg positivity,HBsAg seroclearance occurred in 12(17.9％)patients with an estimated annual inci-dence of HBsAg seroclearance of 3.6％.Patients with EOT HBsAg levels of ≤1000 IU/mL had a higher HBsAg seroclearance rate than those with EOT HBsAg levels of＞1000 IU/mL(33.3％vs.5.4％).The pro-portion of patients with HBsAg ≤1000 IU/mL increased during follow-up.Logistic regression analysis indicated that the EOT HBsAg level was an independent factor for HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL.The optimal EOT HBsAg cutoff for both HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL was 359 IU/mL. Conclusions:Patients with EOT HBsAg negativity experienced no relapse and maintained HBsAg sero-clearance during 5 years of follow-up after NA discontinuation.A higher HBsAg seroclearance rate can be obtained in patients with EOT HBsAg levels of ≤1000 IU/mL during 5 years of follow-up after NA discontinuation.Close monitoring and proper NA retreatment are recommended to guarantee the safety of NA discontinuation.

OBJECTIVE: To investigate the inhibitory effect of Zhenwu Decoction on ventricular hypertrophy in rats with uremic cardiomyopathy and explore the mechanism. METHODS: Cardiocytes isolated from suckling rats were divided into control group and indoxyl sulfate (IS) group, and the protein synthesis was assayed with [H]- leucine incorporation and cellular protein expressions were detected using Western blotting. Fifty SD rats were randomly divided into sham operation group, model group, and low- and high-dose Zhenwu Decoction treatment groups, and except for those in the sham operation group, all the rats underwent 5/6 nephrectomy. Four weeks after the operation, the rats in low- and high-dose treatment groups were given Zhenwu Decoction gavage at the dose of 4.5 g/kg and 13.5 g/kg, respectively; the rats in the sham-operated and model groups were given an equal volume of distilled water. After 4 weeks of treatment, serum levels of IS were determined, and cardiac and ventricular mass indexes were measured in the rats; cardiac ultrasound was performed and Western blotting was used to measure the expressions of BNP, p-ERK1/2, p-p38 and p-JNK in the myocardium. RESULTS: Rat cardiomyocytes treated with IS showed significantly enhanced protein synthesis and increased expression levels of BNP, p-erk1/2, and p-p38 as compared with the control cells ( < 0.01), but the expression of p-jnk was comparable between the two groups. In the animal experiment, the rats in the model group showed significantly increased serum creatinine (SCr) and urea nitrogen (BUN) levels, 24-h urine protein (24 hUpro), plasma IS level, left ventricular mass index (LVMI) and whole heart mass index (HMI) compared with those in the sham group ( < 0.01); Both LVESD and LVEDD were significantly reduced and LVAWS, LVAWD, LVPWS and LVPWD were significantly increased in the model rat, which also presented with obvious cardiomyocyte hypertrophy and increased myocardial expressions of BNP, p-ERK1/2, p-p38 and p-jnk ( < 0.01). Compared with the rats in the model group, the rats treated with low-dose and high-dose Zhenwu Decoction had significantly lowered levels of SCr, BUN, 24 hUpro and IS ( < 0.05) and decreased LVMI and HMI; LVESD, LVEDD, LVPWS, LVAWS, and LVAWD were improved more obviously in the high-dose group, and the myocardial expressions of BNP, p-ERK1/2, p-p38 and p-JNK was significantly downregulated after the treatment. CONCLUSIONS Zhenwu Decoctin can reduce plasma IS levels and inhibit ventricular hypertrophy to delay ventricular remodeling in rats with uremic cardiomyopathy.

Objective: To evaluate the efficacy and safety of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) 25/150/100 mg once daily and dasabuvir (DSV) 250 mg twice daily combined with ribavirin in adult patients of Mainland China with chronic HCV genotype 1b infection and compensated cirrhosis. Methods: An open-label, multicenter, phase 3 clinical trial study was conducted in mainland China, Taiwan, and South Korea. Adult patients with compensated cirrhosis (Metavir score =F4) who were newly diagnosed and treated for hepatitis C virus genotype 1b infection with ombitasvir/paritaprevir/ritonavir and dasabuvir combined with ribavirin for 12 weeks were included. Assessed SVR rate of patients obtained at 12 and 24 weeks after drug withdrawal. Efficacy and safety were evaluated in patients who received at least one time study drugs. Results: A total of 63 patients from mainland China were enrolled, 62 of whom (98.4%) had a baseline Child-Pugh score of 5 points. The overall rate of SVR12 and SVR24 in patients was 100% (95% CI: 94.3% to 100.0%). Most of the adverse events that occurred were mild. The incidence of common (≥10%) adverse events and laboratory abnormalities included elevated total bilirubin (36.5%), weakness (19.0%), elevated unconjugated bilirubin (19.0%) and conjugated bilirubin (17.5%), and anemia (14.3%). Three cases (4.8%) of patients experienced Grade ≥ 3 adverse events that were considered by the investigators to be unrelated to the study drug. None patients had adverse events leading to premature drug withdrawal. Conclusion Mainland Chinese patients with chronic HCV genotype 1b infection and compensated cirrhosis who were treated with OBV/PTV/r plus DSV combined with RBV for 12 weeks achieved 100 % SVR at 12 and 24 weeks after drug withdrawal. Tolerability and safety were good, and majority of adverse events were mild.

Objective: To evaluate the safety and efficacy of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) 25/150/100 mg once daily combined with dasabuvir 250mg, twice daily in non-cirrhotic Chinese adult patients with newly diagnosed and treated chronic HCV genotype 1b infection. Methods: A randomized, double-blind, placebo-controlled, multicenter phase 3 clinical trial was conducted in mainland China, Korea, and Taiwan.Safety and efficacy of OBV/PTV/r plus DSV administered for 12 weeks were evaluated in a newly diagnosed and treated (interferon alpha /pegylated interferon alpha) and ribavirin non-cirrhotic adults with chronic HCVgenotype 1b infection. Patients randomly received OBV/PTV/r plus DSV for 12 weeks (Group A), or placebo for 12 weeks (Group B) followed by an open-label phase of OBV/PTV/r plus DSV for 12 weeks. Sustained response (SVR12) rate obtained at 12 weeks and (SVR24) 24 weeks after discontinuation of treatment, and the incidence of adverse events and laboratory abnormalities after double-blind and open-label phase treatment were assessed. Results: A total of 410 cases of Chinese patients were included and randomly assigned to group A and B (with 205 cases in each group) in a 1:1 ratio. The rates of SVR12 and SVR24 were 99% (95% CI: 94.8% - 99.8%) in the newly diagnosed patients in group A (205 patients) and the rates of SVR12 and SVR24 were 100% in treated patients (95% CI: 96.3% - 100%). Different baseline characteristics had no effect on SVR12 and SVR24 rates. Most of the adverse events occurred were mild, asymptomatic, and≥ 3 laboratory abnormalities during treatment were rare, including elevation of alanine aminotransferase (2 cases in double-blind stage A group), aspartate aminotransferase (Double-blind stage A (3 cases) and total bilirubin (1 case in open-label phase B group); however, those mild adverse events could be recovered after drug withdrawal or discontinuation. only1 person discontinued drugs due to adverse events (Group B, open-label phase). Conclusion The 12 weeks treatment course of OBV/PTV/r combined with DSV produced 99% ~ 100% rates of SVR12 and SVR24 in non-cirrhotic Asian adult patients with newly diagnosed and treated chronic HCV genotype 1b infection, and the tolerance and safety were good.

Objective: To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control. Methods: A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1. The patients in both groups were given oral ribavirin for 48 weeks in addition and then followed up for 24 weeks after drug withdrawal. Abbott Real Time HCV Genotype II was used to determine HCV genotype, and Cobas TaqMan quantitative real-time PCR was used to measure HCV RNA level at 0, 4, 12, 24, 48, and 72 weeks. Adverse events were recorded in detail. The primary efficacy endpoint was sustained virological response (SVR), and a non-inferiority test was also performed. Results: A total of 561 patients with genotype 1/6 CHC were enrolled, among whom 529 received treatment; 90.9% of these patients had genotype 1 CHC. The data of the full analysis set showed that SVR rate was 69.80% (95% CI 65.00%-74.60%) in the trial group and 74.16% (95% CI 67.73%-80.59%) in the control group (P = 0.297 0). The data of the per protocol set (PPS) showed that SVR rate was 80.63% (95% CI 76.04%-85.23%) in the trial group and 81.33% (95% CI 75.10%-87.57%) in the control group (P = 0.849 8), and the 95% CI of rate difference conformed to the non-inferiority standard. The analysis of the PPS population showed that of all subjects, 47.9% achieved rapid virologic response, with a positive predictive value of 93.8%. The incidence rate of adverse events was 96.30% in the trial group and 94.94% in the control group, and the incidence rate of serious adverse events was 5.13% in the trail group and 5.06% in the control group. Conclusion In the regimen of Peg-IFN-α combined with ribavirin for the treatment of genotype 1/6 CHC, the new investigational drug Peg-IFN-α-2b(Y shape, 40 kD) has comparable clinical effect and safety to the control drug Peg-IFN-α-2a.

Objective To evaluate the efficacy of pegylated interferon ( PegIFN ) α-2a plus ribavirin ( RBV) therapy for chronic hepatitis C ( CHC) in non-responders, and to investigate the related influencing factors.Methods A prospective, open, multicenter and randomized study was conducted.A total of 81 CHC non-responders were recruited from 10 clinical centers during February 2009 to November 2011.Patients were randomly assigned into two groups:group A (n=37) was given PegIFNα-2a plus RBV treatment for 72 weeks and group B (n=44) was given PegIFNα-2a plus RBV treatment for 96 weeks.Both groups were followed up for 24 weeks after treatment.Virological responses in two groups were observed, and treatment efficacies among patients with different genotypes, and among those with different previous treatment were compared.SAS software was used for statistical analysis.Results Fifty-two patients ( 28 from group A and 24 from group B) completed the study in total.The rates of rapid virological response ( RVR) , complete early virological response ( cEVR ) , end of treatment viral response ( ETVR ) and sustained virological response (SVR) in group A were 25.0% (7/28), 60.7% (17/28), 67.9%(19/28) and 60.7%(17/28), respectively; while those in the group B were 41.7% (10/24), 70.8%(17/24), 70.8%(17/24) and 70.8% (17/24), respectively; and there were no significant differences between two groups (P>0.05).SVR was observed in 82.9%(29/35) of patients with CC genotype of IL-28B, which was higher than that in patients with other genotypes ( 3/13 ) , and the difference was of statistical significance (P<0.01).There was no significant difference in viral responses between patients previously treated with IFN plus RBV and those treated by IFN only (P>0.05).The rates of RVR, cEVR, ETVR and SVR in patients who were previously treated with IFN were 36.4%(12/33), 81.8%(27/33), 81.8%(27/33) and 75.8%(25/33), and the rates of cEVR, ETVR and SVR were higher than those in patients who were previously treated with PegIFN (P<0.05), but no significant difference was observed in RVR (P>0.05).Adverse events occurred in 38 patients (46.9%), but no severe ones were observed. Conclusion The efficacy of PegIFNα-2a plus RBV therapy for CHC in non-responders is satisfactory, which may influenced by IL-28B genotypes and previous treatment.

OBJECTIVETo perform a prospective,multicenter,open,randomized study to determine a treatment regimen for treatment-naive patients with refractory chronic hepatitis C (RHC) using the predictive value (PV) of early virological response (EVR).

METHODSA total of 438 patients from 18 hospitals were recruited between December 2008 and December 2010 and administered peg-interferon/ribavirin treatment for 12 weeks. Patients who achieved complete EVR (cEVR) were assigned to group A for a 48-week course of treatment, while patients without cEVR were randomly allocated to either group B 1 for a 72-week course of treatment or to group B2 for a 96-week course of treatment. Serum hepatitis C virus RNA levels at baseline,treatment weeks 4, 12 and 24, end of treatment, and post-treatment week 24 were measured and used to evaluate the efficiency of therapy.

RESULTSThe overall sustained virological response (SVR) rate was 85.1%. In all, 91.0% of patients achieved cEVR and were assigned to group A, which had an SVR rate of 90.8%. There was no statistically significant difference in the SVR rates of groups B1 and B2 (29.4% vs. 25.0%, P more than 0.05). The positive PV of rapid virological response (RVR), cEVR and delayed virological response (DVR) for SVR was 93.4%, 90.8% and 77.8% respectively, and the negative PV of RVR, EVR and DVR for SVR was 28.0%, 93.3% and 100% respectively. Overall, 66.9% of the patients experienced adverse events (AEs), but only 1.9% of patients experienced sevcre AEs.

CONCLUSIONThe majority of Chinese RHC treatmentna(i)ve patients (91.0%) can achieve cEVR and a high SVR rate with a low rate of severe AEs using the cEVR guided personal treatment regimen.

OBJECTIVETo investigate the dynamic changes in serum levels of hepatitis B surface antigen (HBsAg) and their relation to hepatic parenchyma cell volume (hepatic cell quantity) at different grades of liver inflammation and stages of hepatic fibrosis in patients with hepatitis B e antigen (HBeAg)-negative chronic hepatitis B.

METHODSSerum HBsAg levels were detected by electrochemilumineseence. Serum HBsAg levels were apportioned according to the hepatic parenchyma cell volume and compared among liver histological inflammation grade (1, 2, 3 and 4) and hepatic fibrosis stage ( I, II, III and IV), respectively.

RESULTSThe levels of serum HBsAg among the four liver histological inflammation grades were:1:6,036.4+/-2,729.4 COI/ml; 2:6,704.6+/-2,457.5 COI/ml; 3:6,332.2+/-2,409.0 COI/ml; 4:6,226.2+/-2,716.0 COI/ml. There were no differences among the groups before apportion (Fbefore apportion=0.564, P=0.640).Serum HBsAg levels apportioned by the hepatic parenchyma cell volume among liver histological inflammation grades were:1:9,174.8+/-4,142.0 COI/ml; 2:10,743.1+/-3,950.3 COI/ml; 3:11,078.0+/-4 230.0COI/ml; 4:11,540.5+/-5,058.8 COI/ml. There were significant differences among the groups after apportion (Fafter apportion =27.354, P<0.001). Serum HBsAg levels among hepatic fibrosis stages were: I: 6,222.1+/-2,665.4 COI/mL; II: 6,706.8+/-2,623.8 COI/ml; III:6 004.5+/-2,625.5 COI/ml; IV:6,455.6+/-2,344.4 COI/ml. There were no differences among groups before apportion (Fbefore apportion=0.768, P=0.513).Serum HBsAg levels apportioned by the hepatic parenchyma cell volume (hepatic cell quantity) among hepatic fibrosis stages were: I :9 417.5+/-4,034.2 COI/ml; II :10,093.3+/-4,183.4 COI/ml; III:10,177.1+/-4,445.0 COI/ml; IV:12,166.6+/-4,418.5 COI/ml. There were significant differences among the groups after apportion (Fafter apportion=57.077, P<0.001).

CONCLUSIONSerum HBsAg levels apportioned by the same hepatic parenchyma cell volume (hepatic cell quantity), rather than serum HBsAg levels, increased with hepatic pathological progress.
