Characterization of Neoschoengastia gallinarum from subtropical China by rDNA and identification of two genotypes based on mitochondrial cox1.

Genetic variations in the 18S ribosomal DNA (18S), 28S ribosomal DNA (28S), second internal transcribed spacer of ribosomal DNA (ITS2), and mitochondrial cytochrome c oxidase subunit 1 (cox1) of Neoschoengastia gallinarum collected from subtropical China were examined. First, a portion of the 18S (p18S), a portion of the 28S (p28S), and the complete ITS2 were separately amplified from individual mites and sequenced. The lengths of the sequences of p18S, p28S, and ITS2 were found to be 1379 bp, 3465~3468 bp, and 200 bp, respectively. The intraspecific sequence variation was 0~0.1% for p28S and 0~1.6% for ITS2, though no variation was observed for p18S, suggesting conservation of rDNA sequences. Second, a portion of the mitochondrial cox1 gene (pcox1) of N. gallinarum was analyzed. The length of the pcox1 sequence is 460 bp, and two distinct groups were observed in N. gallinarum. All pcox1 sequences in group I were identical, and there was only one nucleotide transition observed in group II; however, 7.0~7.2% variations between the two groups were observed, suggesting that two genotypes of N. gallinarum: genotype I and genotype II. Phylogenetic analyses based on pcox1 sequences indicated that N. gallinarum isolates (genotype I or genotype II) clustered into one branch; according to cox1 sequence analysis of Trombiculidae, Walchia hayashii is the closest species. The present study shows that ITS2 rDNA sequence can act as marker for the identification of N. gallinarum samples. Furthermore, analysis of the mitochondrial pcox1 sequence suggests the existence of two genotypes, which has implications for further studies of the ecology and population genetic structures of N. gallinarum.

[Determination of flavonoids constituents in epimedium total flavone capsule and research on its anti-osteoporosis activity].

To develop a rapid resolution liquid chromatography (RRLC) method for the simultaneous determination of epimedoside A, epimedin A1, epimedin A, epimedin B, epimedin C, icariin, baohuosideⅡ, icarisideⅠ, sagittatoside B, 2"-O-rhamnosyl icarisideⅡ, and baohuosideⅠin epimedium total flavone capsule. At the same time, the effects of the above 11 compounds on osteogenic differentiation of MC3T3-E1 cells were investigated by detecting the content of alkaline phosphatase (AKP). The results showed that baohuoside Ⅱ had the highest activities, and both the activities of baohuoside Ⅱ and icariside Ⅰ were stronger than those of icariin.In this study, the content determination method of flavonoid glycosides was established, and the anti-osteoporosis effect of monomers was compared, providing technical support for the study of the pharmacodynamic and mechanism of Epimedium total flavone capsule.

Epidemiological investigation of Mycoplasma Synoviae in native chicken breeds in China.

BACKGROUD: Mycoplasma synoviae (M. synoviae) is widely distributed around the world, and leads to serious economic losses in the world every year. Nevertheless, the incidence and epidemiology of M. synoviae infection in China have remained unclear. RESULTS: In this study we demonstrate that over 9773 broiler chicken flocks in 16 Chinese provinces were affected by M. synoviae between 2010 and 2015. Our epidemiological study revealed that M. synoviae was widely prevalent in multi-aged Chinese native breeder chickens, and the prevalence of M. synoviae in embryos of breeders reached up to 16.29%. In addition, our data showed that chickens aged 14 days or younger carried simultaneously high levels of maternal antibody against M. synoviae and high M. synoviae infection (10%), and low M. synoviae antibody levels in breeders and high proportion of M. synoviae infection in embryos could increase the chances of incidence in the offspring. Finally, our results also indicated that 3- to 7-week-old chickens might be most the susceptible to M. synoviae and, therefore, might play a key role in the horizontal transmission of M. synoviae. CONCLUSION: Our findings suggest that M. synoviae is widely circulating in Chinese native chickens, accordingly, effective control measures are urgently needed to control the spread.

The method is reproducible, simple and reliablethat it can be used for quality control and evaluation of Resina Draconis from different manufacturers.

Sequence and phylogenetic analysis of surface protein genes of emerging H9N2 influenza viruses isolated from poultry in two geographical regions of China.

Subtype H9N2 avian influenza viruses (AIVs) circulating in China have aroused increasing concerns for their impact on poultry and risk to public health. The present study was an attempt to elucidate the phylogenetic relationship of H9N2 AIVs in two geographically distinct regions of China where vaccination is routinely practiced. A total of 18 emerging H9N2 isolates were identified and genetically characterized. Phylogenetic analysis of hemagglutinin (HA) and neuraminidase (NA) genes confirmed that the isolates belonged to the Y280 lineage. Based on the HA genes, the isolates were subdivided into two subgroups. The viruses from Zhejiang Province were clustered together in Group I, while the isolates from Guangdong Province were clustered together in Group II. Antigenic characterization showed that the tested viruses were antigenically different when compared to the current used vaccine strain. It was notable that 14 out of total 18 isolates had an amino acid exchange (Q→L) at position 216 (226 by H3 Numbering) in the receptor-binding site, which indicated that the virus had potential affinity of binding to human like receptor. These results suggest that the emerging viruses have potential risk to public health than previously thought. Therefore, continuous surveillance studies of H9N2 influenza virus are very important to the prognosis and control of future influenza pandemics.

Sustained efficacy of adefovir add-on therapy in chronic hepatitis B patient with a poor virological response to peginterferon alfa.

BACKGROUND: Currently, there is no consensus on the recommendation of peginterferon alfa (pegIFNα) to chronic hepatitis B (CHB) patients with poor viral response (EVR). This study aimed to assess the sustained curative efficacy of adefovir (ADV) add-on therapy in optimizing pegIFNα monotherapy. METHODS: A total of 85 hepatitis B e antigen (HBeAg)-positive CHB patients with poor virological response at month 6 after starting pegIFNα-2a were enrolled, and received either pegIFNα-2a continuing monotherapy (group A, n = 51) or add-on therapy with ADV (group B, n = 34). The treatment duration for all patients was 6 months, and the sustained responses after the end of treatment were evaluated between two groups. RESULTS: The baseline characteristics were comparable between two groups. At months 6 after treatment completion, the sustained virological response (SVR) rates were 31.4% and 73.5%, the sustained biochemical response (SBR) rates were 39.2% and 85.3% in group A and group B respectively, and the difference in either SVR or SBR was statistically significant (both p < 0.001). As compared to patients in group A, significantly more patients in group B obtained HBeAg loss (19.6% vs. 55.9%, p = 0.001) and seroconversion (13.7% vs. 41.2%, p = 0.004). CONCLUSION: ADV add-on therapy could significantly improve and sustain the curative efficacy of CHB patient with poor virological response to pegIFNα-2a monotherapy, but further large well-designed randomized controlled trials are needed to confirm our findings.

Dynamic distribution and tissue tropism of infectious laryngotracheitis virus in experimentally infected chickens.

Infectious laryngotracheitis (ILT), caused by infectious laryngotracheitis virus (ILTV), is an Office International des Epizooties (OIE) notifiable disease. However, we have not clearly understood the dynamic distribution, tissue tropism, pathogenesis, and replication of ILTV in chickens. In this report, we investigated the dynamic distribution and tissue tropism of the virus in internal organs of experimentally infected chickens using quantitative real-time polymerase chain reaction (qPCR) and a histopathological test. The study showed that ILTV could be clearly detected in eight internal organs (throat, trachea, lung, cecum, kidney, pancreas, thymus and esophagus) of infected chickens, whereas the virus was difficult to detect in heart, spleen, proventriculus, liver, brain and bursa. Meanwhile, the thymidine kinase (TK) gene levels in eight internal organs increased from 3 days to 5 days postinfection, and then decreased from 6 days to 8 days postinfection. The log copy number of ILTV progressively increased over 3 days, which corresponds to the clinical score and the result of the histopathological test. The results provide a foundation for further clarification of the pathogenic mechanism of ILTV in internal organs and indicate that throat, lung, trachea, cecum, kidney, pancreas and esophagus may be preferred sites of acute infection, suggesting that the tissue tropism and distribution of ILTV is very broad.

Molecular characterization and phylogenetic analysis of infectious bursal disease viruses isolated from chicken in South China in 2011.

Infectious bursal disease virus (IBDV) is a double-stranded RNA virus that causes immunosuppressive disease in young chickens. Thousands of cases of IBDV infection are reported each year in South China, and these infections can result in considerable economic losses to the poultry industry. To monitor variations of the virus during the outbreaks, 30 IBDVs were identified from vaccinated chicken flocks from nine provinces in South China in 2011. VP2 fragments from different virus strains were sequenced and analyzed by comparison with the published sequences of IBDV strains from China and around the world. Phylogenetic analysis of hypervariable regions of the VP2 (vVP2) gene showed that 29 of the isolates were very virulent (vv) IBDVs, and were closely related to vvIBDV strains from Europe and Asia. Alignment analysis of the deduced amino acid (aa) sequences of vVP2 showed the 29 vv isolates had high uniformity, indicated low variability and slow evolution of the virus. The non-vvIBDV isolate JX2-11 was associated with higher than expected mortality, and had high deduced aa sequence similarity (99.2 %) with the attenuated vaccine strain B87 (BJ). The present study has demonstrated the continued circulation of IBDV strains in South China, and emphasizes the importance of reinforcing IBDV surveillance.

Prevention and treatment of hepatic encephalopathy during the perioperative period of transjugular intrahepatic portosystemic shunt.

Transjugular intrahepatic portosystemic shunt (TIPS) is an established procedure for treating the complications of portal hypertension in liver cirrhosis. While the pathogenesis of postoperative TIPS-related hepatic encephalopathy (HE) has yet to be fully understood, intraoperative portosystemic shunts may provide a pathological basis for the occurrence of postoperative HE in patients with liver cirrhosis. Studies at home and abroad have expressed mixed opinions about TIPS-related HE. This study presents a literature review on the risk factors for and prevention and treatment of perioperative TIPS-related HE in patients with liver cirrhosis, aiming to optimize the procedure and reduce the incidence of postoperative HE.

Rare portal hypertension caused by Abernethy malformation (Type IIC): A case report.

BACKGROUND: Abernethy malformation is a rare congenital vascular malformation with a portosystemic shunt that may clinically manifest as cholestasis, dyspnea, or hepatic encephalopathy, among other conditions. Early diagnosis and classification are very important to further guide treatment. Typically, patients with congenital portosystemic shunts have no characteristics of portal hypertension. Herein, we report an 18-year-old female with prominent portal hypertension that manifested mainly as rupture and bleeding of esophageal varices. Imaging showed a thin main portal vein, no portal vein branches in the liver, and bleeding of the esophageal and gastric varices caused by the collateral circulation upwards from the proximal main portal vein. Patients with Abernethy malformation type I are usually treated with liver transplantation, and patients with type II are treated with shunt occlusion, surgery, or transcatheter coiling. Our patient was treated with endoscopic surgery combined with drug therapy and had no portal hypertension and good hepatic function for 24 mo of follow-up. CASE SUMMARY: This case report describes our experience in the diagnosis and treatment of an 18-year-old female with Abernethy malformation type IIC and portal hypertension. This condition was initially diagnosed as cirrhosis combined with portal hypertension. The patient was ultimately diagnosed using liver histology and subsequent imaging, and the treatment was highly effective. To publish this case report, written informed consent was obtained from the patient, including the attached imaging data. CONCLUSION: Abernethy malformation type IIC may develop portal hypertension, and traditional nonselective beta-blockers combined with endoscopic treatment can achieve high efficacy.

[Characteristics and Source Apportionment of Atmospheric Ion Deposition During Winter and Spring in the Core Area of Beijing].

In recent years, the Ministry of Ecology and Environment and the Beijing Municipal Government have continuously strengthened the control indicators of dustfall. In order to grasp the characteristics and sources of ion deposition in dustfall, the filtration method and ion chromatography were used to determine the dustfall and ion deposition during winter and spring in the core area of Beijing, and the PMF model was carried out to analyze the sources of ion deposition. The results indicated:① the average values of ion deposition and its proportion in dustfall were 0.87 t·(km2·30 d)-1 and 14.2%, respectively. The dustfall and ion deposition on working days were 1.3 times and 0.7 times that on rest days, respectively. ② The coefficient of determination in the linear equations between ion deposition and precipitation, relative humidity, temperature, and average wind speed were 0.54, 0.16, 0.15, and 0.02, respectively. In addition, the coefficient of determination in the linear equations between ion deposition and PM2.5 concentration and dustfall were 0.26 and 0.17, respectively. Therefore, controlling the concentration of PM2.5 was crucial to treating ion deposition. ③ Anions and cations accounted for 61.6% and 38.4%, respectively, in the ion deposition, and SO42-, NO3-, and NH4+ accounted for 60.6% in total. The ratio of anion and cation charge deposition was 0.70, and the dustfall was alkaline. The ρ(NO3-)/ρ(SO42-) in the ion deposition was 0.66, which was higher than that of 15 years ago. ④ The contribution rates of secondary sources, fugitive dust sources, combustion sources, snow-melting agent sources, and other sources were 51.7%, 17.7%, 13.5%, 13.5%, and 3.6%, respectively.

The evaluation and implementation of Direct Analysis in Real Time quadrupole time-of-flight tandem mass spectrometry for characterization and quantification of geniposide in Re Du Ning Injections.

RATIONALE: The Direct Analysis in Real Time (DART) ionization source coupled with a quadrupole time-of-flight tandem mass spectrometry (Q-TOF MS/MS) system has the capability to desorb analytes directly from samples from complex Chinese herbal preparations without sample cleanup or chromatographic separation. METHODS: In this work, a method based on DART/Q-TOF MS/MS has been developed for rapid determination of geniposide present in 'Re Du Ning Injections', a Chinese herbal preparation. The method has been evaluated for both qualitative and quantitative analysis of geniposide in Re Du Ning Injections. RESULTS: Variables including polarity for ion detection, DART gas heater temperature, matrix effect and sample presentation speed were investigated. The quantitative method was validated with respect to linearity, sensitivity, repeatability, precision and accuracy by using both internal and external standards. A comparison of the results obtained using the DART-based method was made with those obtained using a conventional High-Performance Liquid Chromatography/Diode-Array Detector (HPLC/DAD) by analyzing geniposide in four batches of Re Du Ning Injections. CONCLUSIONS: The DART/Q-TOF MS/MS-based method provides a rapid, efficient and powerful method to analyze compounds from complex Traditional Chinese Medicines with limited sample preparation thus reducing time and complexity of quality control for those materials.

Phylogenetic analysis of hemagglutinin genes of 40 H9N2 subtype avian influenza viruses isolated from poultry in China from 2010 to 2011.

Avian influenza virus (H9N2) infection is a major problem of product performance in poultry worldwide. Vaccination is used to limit spread, but more knowledge is needed on the epidemiology of virus subtypes to improve vaccine design. In this study, 40 H9N2 subtype avian influenza viruses (AIVs) were isolated from vaccinated poultry flocks in China from 2010 to 2011. Hemagglutinin (HA) from different virus strains was sequenced and analyzed. We found that the HA genes of these strains shared nucleotide and deduced amino acid homologies that ranged from 90.1 to 92.9 and 91.4 to 95.0 %, respectively, when compared with vaccine strains. Phylogenetic analysis showed that the strains tested could be divided into two major groups. Group I consisted of 24 strains isolated mainly from Eastern and Central China. Group II consisted of 20 strains isolated from Southern China. The cleavage site within the HA protein contained two basic motifs, PSRSSR↓GLF for group I, and PARSSR↓GLF for group II. Additional potential glycosylation sites were found at amino acid position 295 in the HA1 of the isolates in group I, compared with isolates in group II and the vaccine strains. Furthermore, 38 out of the 40 isolates had a leucine residue at position 216 (aa 226 in H3), which was characteristic of human influenza virus-like receptor specificity. In the present study we found that geographical factors play a significant role in virus evolution, and emphasize the importance of continuing surveillance of H9N2 AIVs in chickens in China.

Influence of different portal vein branches on hepatic encephalopathy during intrahepatic portal shunt via jugular vein.

This letter is regarding the study titled 'Targeted puncture of left branch of intrahepatic portal vein in transjugular intrahepatic portosystemic shunt (TIPS) to reduce hepatic encephalopathy'. Prior to the approval of TIPS dedicated stents (Viatorr stents) in China in October 2015, Fluency covered stents were typically used. As Fluency covered stents have a strong support force and axial elastic tension, a 'cap' may form if the stent is located too low at the end of the hepatic vein or too short at the end of the portal vein during surgery, leading to stent dysfunction. Since the blood shunted by the stent is from the main trunk of the portal vein, the correlation between the incidence of postoperative hepatic encephalopathy and the location of the puncture target (left or right portal vein branch) is worth discussion. Notably, no studies in China or foreign countries have proven the occurrence of left and right blood stratification after the accumulation of splenic vein and mesenteric blood flow in the main trunk of the portal vein in patients with cirrhotic portal hypertension.

Lamivudine plus adefovir is a good option for chronic hepatitis B patients with viral relapse after cessation of lamivudine treatment.

AIM: Currently, there is no consensus on the retreatment recommendation of chronic hepatitis B (CHB) patients with viral rebound after cessation of treatment. In the search of reasonable treatment, we compared the efficacy and safety of adefovir (ADV) plus lamivudine (LAM) and LAM alone for the retreatment of patients with viral relapse but without genotypic resistance after cessation of LAM. METHODS: This is a prospective controlled study, and a total of 53 hepatitis B e antigen (HBeAg)-positive patients with viral rebound but without resistance were received either LAM plus ADV or LAM alone treatment. RESULTS: After 1-year treatment, more patients who received LAM plus ADV than those who received LAM alone had ALT normalization (84% versus 53.6%, P = 0.018) or HBV DNA levels below 1000 copies/mL (80% versus 42.9%, P < 0.006). Seven patients receiving LAM plus ADV had HBeAg seroconversion, as compared with 0 in patients receiving ALM alone (28% versus 0%, P = 0.003). During 1-year retreatment, five patients receiving LAM alone had virological breakthrough and all of them had LAM resistance strains (rtM204V/I), while no LAM- or ADV- associated resistance strains were detected in patients receiving LAM plus ADV. All patients receiving LAM plus ADV were well tolerated, and no serious side effects were noted. CONCLUSIONS: Patients treated with LAM plus ADV exhibited significantly greater virological, biochemical and serological responses compared with LAM alone. These data suggested that combination of LAM plus ADV would be a good option for the retreatment of CHB patients with viral relapse after cessation of LAM.

Temporary pacemaker protected transjugular intrahepatic portosystemic shunt in a patient with acute variceal bleeding and bradyarrhythmia: A case report.

BACKGROUND: Esophagogastric varices are a common complication of cirrhosis with portal hypertension and endoscopic treatment has been recognized as a primary preventive and therapeutic option for such patients; however, it should be noted that bradyarrhythmia is regarded as one of the contraindications to endoscopic examination. Meanwhile, acute variceal bleeding may result in a high mortality rate in cirrhotic patients with portal hypertension accompanied by bradyarrhythmia. At present, there is an absence of reports concerning the treatment of such group of patients who underwent transjugular intrahepatic portosystemic shunt (TIPS). The present report details the case of a cirrhotic patient with acute variceal bleeding accompanied by bradyarrhythmia who underwent TIPS under temporary pacemaker protection. CASE SUMMARY: We report the case of a 64-year-old male patient who was confirmed with bradyarrhythmia by ambulatory electrocardiogram 24 h before the operation. The patient was successfully treated by TIPS under temporary pacemaker protection. CONCLUSION: In terms of cirrhotic patients with abnormal cardiac electrophysiological conduction, TIPS may be effective in reducing the complications of portal hypertension following the exclusion of severe pulmonary hypertension and heart failure, showing moderate feasibility in clinical applications.

Clinical efficacy of antiviral therapy in patients with hepatitis B-related cirrhosis after transjugular intrahepatic portosystemic shunt.

BACKGROUND: As a country with a high burden of hepatitis B, China has about 86 million cases of hepatitis B virus infection, ranking the first in the world. Currently, there are about 390000 deaths due to hepatitis B-related complications such as liver cirrhosis and liver cancer every year. Consequently, how to control portal hypertension, improve liver functional reserve, and reduce the incidence of hepatic failure and liver cancer in such patients is the focus of current clinical attention. Previous clinical study in our center suggested that at 24 mo after transjugular intrahepatic portosystemic shunt (TIPS), the liver functional reserve of patients with hepatitis B cirrhosis was better than that of patients with alcohol-induced and immune cirrhosis, which may be related to the effective etiological treatment. AIM: To investigate the clinical efficacy of three first-line antiviral drugs recommended by the guidelines of prevention and treatment for chronic hepatitis B in China (2019) in the treatment of patients with hepatitis B-related cirrhosis who had received a TIPS. METHODS: The clinical data of 137 patients with hepatitis B-related cirrhosis with portal hypertension after receiving TIPS at our centre between March 2016 and December 2020 were analysed retrospectively. According to different anti-viral drugs, the patients were divided into entecavir (ETV) (n = 70), tenofovir alafenamide fumarate (TAF) (n = 32), and tenofovir disoproxil fumarate (TDF) (n = 35) groups. The cumulative incidence of hepatic encephalopathy and hepatocellular carcinoma, survival, and changes in hepatic reserve function and glomerular filtration rate in patients treated with different antiviral drugs within 24 mo after surgery were investigated. RESULTS: At 24 mo after surgery, the Child-Pugh score in the TAF group (6.97 ± 0.86) was lower than that in the TDF (7.49 ± 0.82; t = -2.52, P = 0.014) and ETV groups (7.64 ± 1.17; t = -2.92, P = 0.004). The model for end-stage liver disease score in the TAF group at 24 mo after surgery was 9.72 ± 1.5, which was lower than that in the TDF (10.74 ± 2.33; t = -2.09, P = 0.040) and ETV groups (10.97 ± 2.17; t = -2.93, P = 0.004). At 24 mo after surgery, the estimated glomerular filtration rate (eGFR) in the TAF group (104.41 ± 12.54) was higher than that in the TDF (93.54 ± 8.97) and ETV groups (89.96 ± 9.86) (F = 21.57, P < 0.001). CONCLUSION: At 24 mo after surgery, compared with TDF and ETV, TAF has significant advantages in the improvement of liver functional reserve and eGFR.
