Efficacy of erzhu jiedu recipe on hepatitis B cirrhosis with hyperalphafetoproteinemia: A randomized, double-blind, placebo-controlled clinical trial.

BACKGROUND: Hepatitis B cirrhosis with hyperalphafetoproteinemia is the intermediate stage of liver cirrhosis progressing to hepatocellular carcinoma (HCC), there is no effective way to treat precancerous lesions of liver in modern medicine. In recent decades, clinical and experimental evidence shows that Chinese medicine (CM) has a certain beneficial effect on Hepatitis B Cirrhosis. Therefore, this trial aims to evaluate the efficacy and safety of a CM erzhu jiedu recipe (EZJDR) for the treatment of Hepatitis B Cirrhosis with Hyperalphafetoproteinemia. METHODS: We designed a randomized, double blind, placebo-controlled clinical trial. A total of 72 patients of Hepatitis B Cirrhosis with hyperalphafetoproteinemia were randomized in 2 parallel groups. Patients in the control group received placebo granules similar to the EZJDR. In the EZJDR group, patients received EZJDR twice a day, after meals, for 48 weeks. The primary efficacy measures were changes in serum alpha-fetoprotein (AFP) and alpha-fetoprotein alloplasm (AFP-L3); The secondary indicators of efficacy are changes in liver function indicators, HBV-DNA level; Liver stiffness measurement (LSM); Hepatic portal vein diameter; T lymphocyte subgroup indexes during treatment. All data will be recorded in case report forms and analyzed by Statistical Analysis System software. Adverse events will also be evaluated. RESULTS: The results showed that EZJDR can significantly inhibit the levels of AFP and AFP-L3 in patients with hepatitis B cirrhosis and hyperalphafetoproteinemia and have good security. ETHICS AND DISSEMINATION: The study protocol was approved by the Medical Ethics Committee of Shuguang Hospital, affiliated with University of Traditional Chinese Medicine, Shanghai (NO.2018-579-08-01). TRIAL REGISTRATION: This trial was registered on Chinese Clinical Trial Center (NO.ChiCTR1800017165).

Long-Term Traditional Chinese Medicine Combined with NA Antiviral Therapy on Cirrhosis Incidence in Chronic Hepatitis B Patients in the Real-World Setting: A Retrospective Study.

OBJECTIVE: To evaluate the impact of long-term Traditional Chinese Medicine (TCM) syndrome differentiation combined with antiviral therapy with Nucleos (t) ide analogues (NAs) on the incidence of cirrhosis in patients with chronic hepatitis B. METHODS: This retrospective cohort study included 521 patients with chronic hepatitis B who underwent a treatment course of ≥3 years from 1998-2019. Of the 521 patients, 261 were defined as TCM users while 260 were TCM nonusers (control group). All the enrolled subjects were followed up until February 2019 to measure the incidence and hazard ratio (HR) of cirrhosis, and the Cox proportional hazards regression model was used to analyze the independent factors affecting the occurrence of cirrhosis. RESULTS: The cumulative incidence of TCM users and nonusers was 6.9% and 13.5%, respectively (P=0.013). Results of the Kaplan-Meier analysis demonstrated that TCM users had a significantly lower cumulative incidence of cirrhosis than TCM nonusers (P=0.011), and TCM users had a significantly lower liver cirrhosis risk than TCM nonusers (adjusted HR = 0.416, 95% CI, 0.231-0.749). The histological evaluation revealed improved fibrosis in 45.0% of TCM users and 11.1% of TCM nonusers (P=0.033). The analysation of the prescriptions including total 119 single Chinese herbs medicinal demonstrated that "replenish qi and fortify the spleen," "clear heat and dispel dampness," and "soothe the liver and regulate qi" are the main treatment methods of TCM for CHB. CONCLUSIONS: Our study demonstrated that long-term TCM use may attenuate liver cirrhosis risk in patients with chronic hepatitis B (CHB).

Baicalin Is Curative Against Rotavirus Damp Heat Diarrhea by Tuning Colonic Mucosal Barrier and Lung Immune Function.

BACKGROUND: Previous studies have indicated that rotavirus (RV) is a causative factor for diarrhea and gastroenteritis in pediatric and neonatal settings. Baicalin has many functions, including antibacterial, antiinflammatory, and antihypertensive activities. However, the immunological mechanism of RV-induced diarrhea with heat-dampness syndrome (RV-DH) remains unclear. AIMS: The aim of this study is to explore the role of baicalin in RV-DH diarrhea and its underlying mechanism. METHODS: A mouse model of pediatric RV-DH diarrhea was established and treated with baicalin. The concentrations of cytokines were detected by enzyme-linked immunosorbent assay. Messenger RNA (mRNA) expression levels were detected by quantitative real-time polymerase chain reaction (qRT-PCR), while protein expression levels were determined by Western blotting and immunohistochemistry. Flow cytometry was used to detect the frequency of lymphocytes. RESULTS: The concentrations of interleukin-1ß (IL-1ß), IL-2, IL-6, IL-8, RVvb, and secretory immunoglobulin A (SIgA) in bronchoalveolar lavage fluid (BALF) and colonic mucosa were significantly increased in the RV-DH group. Decreased expression of occludin, claudin-1, and zonula occludens-1 (ZO-1) indicated loss of tight junction function and disturbances in intestinal mucosal permeability in the RV-DH group. Flow cytometry analysis showed a high rate of CD8+ lymphocytes and low amount of CD4+ lymphocytes in the RV-DH group. Treatment of RV-DH mice with baicalin significantly reduced the duration of diarrhea and ameliorated the symptoms and pathological and immunological changes. Furthermore, baicalin inhibited STAT1 and activated STAT3 signaling pathways. CONCLUSIONS: These findings indicate the curative and immunoregulatory properties of baicalin and have direct practical and clinical relevance for the treatment of RV-DH enteritis in humans.

Investigation of the Capacitance-Voltage Electrical Characteristics of Thin-Film Transistors Caused by Hydrogen Diffusion under Negative Bias Stress in a Moist Environment.

In this study, the impact of moisture on the electrical characteristics of an amorphous In-Ga-Zn-O thin-film transistor (a-IGZO TFT) was investigated. In commercial applications of such TFTs, high stability and quality performance in humid environments are essential. During TFT operation under ambient moisture, the electrolysis of water molecules occurs via the tip electric field effect. Hydrogen diffuses from the etch-stop layer or back-channel into the main channel under a negative electric field. The hydrogen atoms act as shallow donors (which causes the carrier concentration in the channel to rise), causing the threshold voltage (VTH) to shift in the negative direction. Hydrogen diffusion from the overlap of the source/drain and gate electrodes to the channel center caused by the tip electric field induces a significant barrier lowering and VTH shifts in a short-channel device. However, under negative bias stress (NBS) in ambient moisture, the negative VTH shift is more obvious in short- than in long-channel devices, indicating suppressed hydrogen diffusion in long-channel devices. This is attributed to the electrolysis of water by the tip electric field at the source, drain, and gate electrodes, which causes hydrogen to diffuse to the center of the channel. Here, a novel physical model of the capacitance-voltage (C-V) electrical property changes under ambient moisture is proposed, based on the early appearance of abnormalities in the C-V measurements. The electrolysis of water caused by the tip electric field and electrical abnormalities caused by hydrogen diffusion into the a-IGZO active layer are explained by this model. A secondary-ion mass spectrometry analysis shows that hydrogen content in the channel generally increases under NBS in ambient moisture. The degradation behavior due to moisture in a-IGZO is clarified. Thus, inhibiting the tip electric field may benefit future flexible-display and gas-sensing applications.

No direct correlation between rotavirus diarrhea and breast feeding: A meta-analysis.

BACKGROUND: Some studies indicated that children with exclusive breast feeding had a reduction in the prevalence of rotavirus diarrhea, while some others held the opposite views. In this study, we aimed to systematically find the associations between rotavirus diarrhea and breast feeding. METHODS: A literature search up to June 2016 in electronic literature databases, including PubMed and Embase, was performed. The Newcastle-Ottawa Scale was used to conduct the quality assessment of all the selected studies. Statistical analyses were performed using the R package version 3.12 (R Foundation for Statistical Computing, Beijing1, China, meta package), and odds ratio (OR) and 95% confidence interval (CI) were used to assess the strength of the association. The heterogeneity was assessed by Cochran's Q-statistic and I2 test, and the sensitivity analysis was performed by trimming one study at a time. RESULTS: A total of 17 articles, which included 10,841 participants, were investigated in the present meta-analysis. There was no significant difference between the case group and control group (OR, 0.59 95% CI 0.33-1.07) in the meta-analysis of exclusive breast feeding, and no significant difference was found between the case group and the control group (OR, 0.86; 95% CI 0.63-1.16) in the meta-analysis of breast feeding. No significant difference was found between the case group and control group (OR, 0.78 95% CI 0.59-1.04) for all quantitative data. CONCLUSIONS: There may be no direct correlation between rotavirus diarrhea and breast feeding.

Effect of Shuanghu Qinggan Granule () and Yigan Yiqi Jieyu Granule () plus lamivudine on chronic hepatitis B patients: A randomized double-blind placebo-controlled trial.

OBJECTIVE: To observe the clinical efficacy and safety of Shuanghu Qinggan Granule ( , SQG) plus Yigan Yiqi Jieyu Granule (, YYJG) combined with lamivudine (LAM) on chronic hepatitis B (CHB) patients. METHODS: The study was a multicenter, randomized, double-blinded and parallel controlled trial. A total of 320 patients were randomly allocated into 2 groups equally: 160 patients (treatment group) were given SQG and YYJG combined with LAM; and 160 patients (control group) were given LAM plus Chinese herb placebo, respectively. Liver functions, hepatitis B envelop antigen (HBeAg) titer levels, and hepatitis B virus DNA (HBV-DNA) load were monitored. RESULTS: (1) In the 48th week, the treatment group showed superior HBeAg seroconversion rate than that in the control group (38.0% vs. 24.0%, P<0.05). (2) In the 48th week, the treatment group demonstrated lower HBeAg titer than that in the control group (P<0.05). (3) In the 12th, 24th, 48th week, there was no statistical significance in HBV-DNA response rate between the two groups. (4) In the 12th week, the level of glutamyl transpeptidase (GGT) was significantly decreased in the treatment group compared with the control group (P<0.05); in the 36th week, the levels of alanine aminotransferase and aspartate transaminase were significantly lower in the treatment group than those in the control group (P<0.05). CONCLUSION: The protocol of SQG and YYJG combined with LAM to treat CHB showed superior efficacy than LAM monotherapy.

Design of a terahertz photonic crystal transmission filter containing ferroelectric material.

The ferroelectric material KTaO3 (KTO) has a very high refractive index, which is advantageous to the photonic crystal (PC) design. KTO polycrystalline crystal has a high extinction coefficient. In this work, we perform a theoretical study of the transmission properties of a PC bandpass filter made of polycrystalline KTO at terahertz (THz) frequencies. Our results show that the defect modes of usual PC narrowband filters no longer exist because of the existence of the high loss. We provide a new PC structure for the high-extinction materials and show that it has defect modes in its transmittance spectra, providing a possible bandpass filter design in the THz region.

Antiviral activities of atractylon from Atractylodis Rhizoma.

Atractylodis Rhizoma is a traditional medicinal herb, which has antibacterial, antiviral, anti­inflammatory and anti­allergic, anticancer, gastroprotective and neuroprotective activities. It is widely used for treating fever, cold, phlegm, edema and arthralgia syndrome in South­East Asian nations. In this study, 6 chemical compositions of Atractylodis Rhizoma were characterized by spectral analysis and their antiviral activities were evaluated in vitro and in vivo. Among them, atractylon showed most significant antiviral activities. Atractylon treatment at doses of 10­40 mg/kg for 5 days attenuated influenza A virus (IAV)­induced pulmonary injury and decreased the serum levels of interleukin (IL)­6, tumor necrosis factor­α and IL­1ß, but increased interferon­ß (IFN­ß) levels. Atractylon treatment upregulated the expression of Τoll­like receptor 7 (TLR7), MyD88, tumor necrosis factor receptor­associated factor 6 and IFN­ß mRNA but downregulated nuclear factor­κB p65 protein expression in the lung tissues of IAV­infected mice. These results demonstrated that atractylon significantly alleviated IAV­induced lung injury via regulating the TLR7 signaling pathway, and may warrant further evaluation as a possible agent for IAV treatment.

[Distribution of Syndrome Types of Chinese Medicine in Acute Infectious Diarrhea].

OBJECTIVE: To observe syndrome types of Chinese medicine (CM) and distribution features of acute infectious diarrhea patients. METHODS: A retrospective study was performed in 465 acute infectious diarrhea patients. The distribution of CM syndrome and syndrome types in different seasons and genders were analyzed. RESULTS: Lack of appetite [381 (81.94%)], fatigue [350 (75.27%)], abdominal pain [338 (72.69%)], tenesmus [325 (69.89%)], anal scorching hot [276 (59.35%)], nausea [25 (55.48%)], diarrhea [249 (53.55%)], short yellow-urine [240 (51.61%)], thirsty [210 (45.16%)], and abdominal distention [206 (44.30%)] were most often seen. The syndrome distribution were sequenced as intestinal damp heat syndrome [268 (57.63%)], dyspeptic retention in intestine and stomach syndrome [106 (22.80%)], cold-damp invading exterior syndrome [47 (10.11%)], Pi-Wei qi deficiency syndrome [23 (4.95%)], cold-damp disturbing Pi syndrome [21 (4.52%)]. The incidence ratio of intestinal damp heat syndrome was the highest in autumn (P < 0.01), while that of cold-damp invading exterior syndrome was the highest in winter (P < 0.01). Cold-damp disturbing Pi syndrome was more often seen in females than in males (P < 0.01), and its incidence ratio was the highest in autumn (P < 0.05). The incidence ratio of dyspeptic retention in intestine and stomach syndrome was the highest in winter (P < 0.01). CONCLUSIONS: Intestinal damp heat syndrome was the most often seen in acute infectious diarrhea. Incidence ratios of in- testinal damp heat syndrome and cold-damp disturbing Pi syndrome were higher in autumn, while those of cold-damp invading exterior syndrome and dyspeptic retention in intestine and stomach syndrome were higher in winter. Cold-damp disturbing Pi syndrome was more often seen in females.

A randomized, open-label clinical study of combined pegylated interferon Alfa-2a (40KD) and entecavir treatment for hepatitis B "e" antigen-positive chronic hepatitis B.

BACKGROUND: Treatment with pegylated interferon (peg-IFN) alfa-2a (40KD) results in hepatitis B "e" antigen (HBeAg) seroconversion 6 months after treatment in up to 36% of HBeAg-positive chronic hepatitis B patients. This study explored the efficacy of a novel combination of peg-IFN alfa-2a and entecavir (ETV), a potent nucleoside analogue. METHODS: In total, 218 treatment-naive Chinese HBeAg-positive patients were randomized to peg-IFN alfa-2a (180 µg/week) for 48 weeks, either as monotherapy (n = 72), or with 24 weeks of ETV (0.5 mg/daily) added at week 13 (ETV add-on, n = 73), or pretreatment with a 24-week course of ETV, starting peg-IFN alfa-2a at week 21 (ETV pretreatment, n = 73). The primary endpoint was reduction in quantitative HBeAg from baseline to 24 weeks posttreatment. RESULTS: Significant reductions in HBeAg from baseline were achieved in all treatment groups 24 weeks posttreatment; reductions were comparable across treatment arms (shown as log10 Paul Ehrlich international units [PEIU]/mL): monotherapy: -1.4 (SD, 1.8); ETV add-on: -1.6 (SD, 1.8); ETV pretreatment: -1.3 (SD, 1.7). Rates of HBeAg seroconversion were similar across treatment groups posttreatment (monotherapy: 22 [31%]; ETV add-on: 18 [25%]; ETV pretreatment: 19 [26%]). Significantly greater reductions of hepatitis B virus DNA were achieved with ETV add-on while on treatment, but were not sustained posttreatment. Safety profiles were comparable between treatment groups; adverse events were experienced by 62 (86%) monotherapy, 65 (89%) ETV add-on, and 58 (81%) ETV pretreatment patients. CONCLUSIONS: Neither ETV add-on nor ETV pretreatment demonstrated superiority compared with 48 weeks of peg-IFN alfa-2a monotherapy. The optimal treatment strategy using nucleos(t)ide analogues and peg-IFN alfa-2a remains to be determined. Clinical Trials Registration. NCT00614471.

[Effects of nano-selenium on antioxidant capacity and histopathology of Cyprinus carpio liver under fluoride stress].

To evaluate the protection effect of nano-selenium (NSe) on the antioxidant capacity and histopathology of Cyprinus carpio liver under fluoride stress, a total of 750 C. carpio individuals were randomly divided into five groups, i. e., no fluoride stress and NSe addition (CK), fluoride (100 mg F- x L(-1))-stressed (FS), and fluoride-stressed plus NSe added with a dosage of 0.1 mg Se x L(-1) (NSe L), 0.5 mg Se x L(-1) (NSe M), and 1.0 mg Se x kg(-1)(NSe H). The NSe was mixed with fish foods, and the fishes of FS and NSe groups were exposed to the fluoride stress for 30 days. As compared with CK, fluoride stress decreased the SOD, CAT, and GSH-Px activities and increased the MDA content of C. carpio liver, and induced a definite damage on the histopathology of the liver. Compared with FS, NSe increased the liver SOD, CAT, and GSH-Px activities, decreased the liver MDA content, and mitigated the damage of fluoride stress on the histopathology of the liver. The results demonstrated that in some extent, the addition of NSe into fish foods could alleviate the decline of the antioxidant capacity of C. carpio liver and the damage on the liver histopathology caused by fluoride stress.

[Genotypes distribution of hepatitis C virus through multi-center, large sample studies among chronic hepatitis C patients in Chinese Han population].

OBJECTIVE: To understand the distribution of hepatitis C virus (HCV) genotypes in China. METHODS: A national multi-center, large sample epidemiological survey was carried out and certified by an international third-party testing organization. Internationally accepted method for sequencing analysis of viral genotype was used. RESULTS: Patients were those suffered from the 4 major genotypes of chronic hepatitis C, including nine subtypes, which were dominated by genotype 1 (69.6%), with type 1b in particular (accounting for 68.38%). Among the rare gene-6, we saw more subtypes of 6a. In the south, central, and north areas, there was no significant difference seen between the south and the north areas in the distribution of the genotype 1. However, the rate of gene type 2a increased gradually from south to north. In terms of less common type of gene 3b and gene-6, they were seen mainly in the southern provinces. CONCLUSION: In China, Patients with chronic hepatitis C had 4 HCV genotypes, with 9 subtypes. The rarely seen genotypes 3b and 6 were mainly distributed in the southern provinces.

[Syndrome distribution among patients with chronic hepatitis C and interventions of integrated traditional Chinese and Western medicine: study protocol].

BACKGROUND: Chronic hepatitis C is one of the major causes of end-stage liver disease with a high incidence rate, amounting to a grave and serious problem of public health. Currently, interferon-based (with or without ribavirin) antiviral therapy has limited use due to its stringent indications, possible contraindications and side effects. Traditional Chinese medicine (TCM) may have advantages in the prevention and treatment of chronic hepatitis C and it is of significant value to discover the advantages. Through this research, a safe and effective treatment protocol of TCM or integrated TCM and Western medicine for chronic hepatitis C can be formed. To this end, during China's Eleventh Five-Year Plan, special research projects on acquired immune deficiency syndrome (AIDS), viral hepatitis and the other major infectious diseases were established. Our studies on chronic hepatitis C constitute one of the major special research topics. METHODS AND DESIGN: Clinical information of patients with chronic hepatitis C will be first collected in a large, multicenter epidemiological survey. Positive symptoms will be analyzed by rapid cluster analysis, principal constituent analysis and factor analysis, and syndrome types will be diagnosed based on expert advice. Concurrently, a large, multicenter, randomized, parallel-group prospective study will be launched based on evidence-based medical principles to evaluate the effects and safety of the treatment protocol for chronic hepatitis C. The evaluated indexes will include the normalization rate of liver function, virological improvement and quality of life improvement for the short-term efficacy and the incidence of liver cirrhosis and (or) primary liver cancer and mortality for the long-term efficacy. DISCUSSION: This study will investigate the TCM syndrome differentiation norms and the syndrome distribution rules of chronic hepatitis C and evaluate the efficacy and safety of a treatment protocol for chronic hepatitis C based on TCM theory or combined treatment of TCM and Western medicine. The study results will be helpful to developing a TCM treatment program for chronic hepatitis C. TRIAL REGISTRATION: The research program was registered in the Chinese Clinical Trial Registry in English and Chinese in January 2010. REGISTRATION NUMBER: ChiCTR-TRC-10000770.

Clinical observation on treatment of 32 patients with measles by qingzhen decoction.

OBJECTIVE: To observe the clinical effect of Qingzhen Decoction (QZD) on measles. METHODS: Adopting the randomizing digital table, 62 patients with measles were assigned to two groups, 32 in the treated group and 30 in the control group. All patients were treated with routine therapy, but QZD was given to the treated group additionally for 5 days. Changes of clinical symptoms, blood routine and liver function before and after treatment were observed, and the medical cost was calculated. RESULTS: After the 5-day treatment, the normalization rate of irritative cough in the treated and the control group was 88.9% (24/27) and 56.0% (14/25) respectively, that of conjunctival congestion was 90.0% (27/30) and 65.5% (19/29) respectively, showing significant differences between groups (P<0.05). The liver function normalization rate in the two groups was 28.6% (2/7) and 25.0% (2/8), and the average medical cost yen 740.7 and yen 749.3, respectively. The total effective rate in the two groups was 96.9% and 93.3% respectively, showing insignificant difference between groups (P>0.05). CONCLUSION: QZD could actively improve the respiratory symptoms like irritative cough and the inflammatory symptoms of eye like conjunctival congestion in patients with measles.

[Portal hemodynamics in patients with different syndromes of cirrhosis].

OBJECTIVE: To explore the relationship between the portal hemodynamics or the indices of liver fibrosis and the liver function score in patients with different traditional Chinese medical syndromes of liver cirrhosis. METHODS: One hundred and forty-seven cases of liver cirrhosis with different syndromes were included in the study. Diameters and blood flow velocities of the portal vein and splenic vein were tested by color Doppler sonarography. The indices of liver function (TBIL, ALT, AST, Alb, Glb, PTA) and the indices of hepatic fibrosis (HA, PC-III, LN, VI-C) were tested. RESULTS: The diameters of portal vein in liver cirrhosis patients with different syndromes (internal accumulation of of damp-heat, stagnation of liver-qi, superabundance of dampness due to spleen-asthenia, asthenia of liver and kidney yin, asthenia of spleen and kidney yang, blood stasis) were not significantly different. The blood flow velocities and flow volumes of portal vein in patients with the blood stasis syndrome and the internal accumulation of damp-heat syndrome were significantly different (P < 0.05). The diameter of splenic vein in patients with the internal accumulation of damp-heat syndrome was significantly different to that of the asthenia of liver and kidney yin syndrome, or the blood stasis syndrome, or the asthenia of spleen and kidney yang syndrome, respectively (P < 0.05 or P < 0.01). The blood flow velocity of splenic vein in patients with the blood stasis syndrome or the asthenia of spleen and kidney yang syndrome was significantly different to that of the internal accumulation of damp-heat syndrome, or the stagnation of liver-qi syndrome, or the asthenia of liver and kidney yin syndrome, respectively (P < 0.01). The blood flow volume of splenic vein in patients with the internal accumulation of damp-heat syndrome was significantly different to that of the asthenia of liver and kidney yin syndrome, or the asthenia of spleen and kidney yang syndrome, or the blood stasis syndrome, respectively (P < 0.01). The liver cirrhosis indices HA and PC-III in patients with the asthenia of liver and kidney yin syndrome were significantly different to those of the internal accumulation of damp-heat syndrome (P < 0.05). In Child-Pugh classification, the incidence of Child-Pugh C was the highest in the asthenia of spleen and kidney yang syndrome, while the incidence of Child-Pugh A was the highest in the stagnation of liver qi syndrome. CONCLUSION: The changes of portal vein dynamics in liver cirrhosis patients with the asthenia of liver and kidney yin syndrome, or the asthenia of spleen and kidney yang syndrome, or the blood stasis syndrome are significantly different to those of the internal accumulation of damp-heat syndrome and the stagnation of liver-qi syndrome.
