Objective: To investigate the distribution of HCV genotypes in Chinese Han population with chronic hepatitis C ( CHC ) . Methods: This randomized multicenter study included 1 014 CHC patients from 28 hospitals in different regions of China.SPSS 20.0 was applied to analyze the relationship among region, HCV genotype, gender and the replication level of HCV-RNA.Results: HCV 1 genotype (56.80%) was the most common genotype.The majority of CHC patients were of genotype 1, 2, 3, 6 in the order of frequency, except those in southwestern, southern and central China.HCV 1, 2, 3, 6 genotypes were most common among male patients in southern China; among female patients in northern China; among male patients in northern and northwestern China and among male patients in northwestern China, respectively ( all P <0 .05 ) .There was no statistical significance between different genders in other regions.The high viral load was more common than the low viral load among HCV 1, 2, 3, 6 genotype-infected patients.Conclusion: There are different distributions of HCV genotypes among the different regions. In addition, HCV genotypes are correlated with gender and HCV-RNA load.

The breeding of domestic rabbits (Oryctolagus cuniculus) for human consumption has a long tradition in China. Infections that can affect the production of meat or even be transmitted from animals to humans are important to monitor, especially for public health reasons as well as for their impact on animal health. Thus, a total of 1,132 domestic rabbit sera from 4 regions in China were collected for serological screening for Encephalitozoon cuniculi and for Toxoplasma gondii by ELISA and modified agglutination test (MAT), respectively. Antibodies to E. cuniculi were detected in 248/1,132 (21.9%) sera tested while antibodies against T. gondii revealed a seroprevalence of 51/1,132 (4.5%). We believe that the present results are of epidemiological implications and public health importance due to the acknowledged susceptibility of humans to E. cuniculi and T. gondii infections. Therefore, routine screening tests of domestic rabbits are proposed considering the zoonotic potential of these parasites.

OBJECTIVETo investigate the effect of adipose stromal vascular fraction cells (SVFs) with VEGF on the neovascularization of free fat transplantation.

METHODSSVFs were obtained from subcutaneous fat and labelled with DiI. 0.3 ml autologous fat tissue was mixed with 0.2 ml cells: 1) autologous SVFs with VEGF (Group A); 2) autologous SVFs (Group B); 3) complete DMEM (Group C) And then the mixture was injected randomly under the back skin of 12 nude mice. The transplanted fat tissue in three groups was harvested at 2 months after implantation. Wet weight and diameter of fat grafts was measured. After HE and CD31 staining,blood vessel density, viable adipocytes and fibrous proliferation were observed.

RESULTSTrace of SVFs labeled by DiI in vivo could be detected by fluorescent microscope. The wet weight of fat grafts was (191.90 +/- 9.81) mg in group A, (177.01 +/- 10.50) mg in group B, and (92.05 +/- 8.30) mg in group C (P<0.01). The diameter of fat grafts was (0.49 +/- 0.24) cm in group A, (0.40 +/- 0.26) cm in group B, and (0.32 +/- 0.28) cm in group C (P<0.01). Histological analysis showed the blood vessel density was (14.58 +/- 2.06)/HPL in group A, (11.55 +/- 2.18)/HPL in group B, (7.87 +/- 1.55)/HPL in group C. Compared with group B and group C, group A had more adipose tissue with less fat necrosis and fibrosis and had significantly higher capillary density.

CONCLUSIONSThe autologous adipose stromal vascular fraction cells with VEGF could improve the neovascularization of free fat significantly. It indicates a wide clinical application in the future.

The development of traditional Chinese medicine (TCM) diagnosis and treatment has undergone multiple paradigms, evolving from sporadic experiential practices to systematic approaches in syndrome differentiation and treatment and further integration of disease and syndrome frameworks. TCM is a vital component of the medical system, valued alongside Western medicine. Treatment based on syndrome differentiation embodies both personalized treatment and holistic approaches; however, the inconsistency and lack of stability in syndrome differentiation limit clinical efficacy. The existing integration of diseases and syndromes primarily relies on patchwork and embedded systems, where the full advantages of synergy between Chinese and Western medicine are not fully realized. Recently, driven by the development of diagnosis and treatment concepts and advances in analytical technology, Western medicine has been rapidly transforming from a traditional biological model to a precision medicine model. TCM faces a similar need to progress beyond traditional syndrome differentiation and disease-syndrome integration toward a more precise diagnosis and treatment paradigm. Unlike the micro-level precision trend of Western medicine, precision diagnosis and treatment in TCM is primarily reflected in data-driven applications that incorporate information at various levels, including precise syndrome differentiation, medication, disease management, and efficacy evaluation. The current priority is to accelerate the development of TCM precision diagnosis and treatment technology platforms and advance discipline construction in this area.

OBJECTIVETo investigate the distribution of HCV genotypes in Chinese Han population with chronic hepatitis C (CHC).

METHODSThis randomized multicenter study included 1 014 CHC patients from 28 hospitals in different regions of China. SPSS 20.0 was applied to analyze the relationship among region, HCV genotype, gender and the replication level of HCV-RNA.

RESULTSHCV 1 genotype (56.80%) was the most common genotype. The majority of CHC patients were of genotype 1, 2, 3, 6 in the order of frequency, except those in southwestern, southern and central China. HCV 1, 2, 3, 6 genotypes were most common among male patients in southern China; among female patients in northern China; among male patients in northern and northwestern China and among male patients in northwestern China, respectively (all P <0.05). There was no statistical significance between different genders in other regions. The high viral load was more common than the low viral load among HCV 1, 2, 3, 6 genotype-infected patients.

CONCLUSIONThere are different distributions of HCV genotypes among the different regions. In addition, HCV genotypes are correlated with gender and HCV-RNA load.

As arsenic widely exists in nature and has been used in the pharmaceutical preparations, the traditional Chinese medicine(TCM) with arsenic include realgar(As_2S_2 or As_4S_4), orpiment(As_2S_3), and white arsenic(As_2O_3). Among the above representative medicine, the TCM compound formulas with realgar are utilized extensively. Just in Chinese Pharmacopoeia(2020 edition), there are 37 Chinese patent medicines including realgar. The traditional element analysis focuses on the detection of the total amount of elements, which neglects the study on the speciation and valence of elements. The activity, toxicity, bioavailability, and metabolic pathways of arsenic in vivo are closely related to the existence of its form, and different forms of arsenic have different effects on organisms. Therefore, the study on the speciation and valence of arsenic is of great importance for arsenic-containing TCMs and their compound formulas. This paper reviewed four aspects of the speciation and valence of arsenic, including property, absorption and metabolism, toxicity, and analytical assay.

Fermented Chinese medicine has long been used. Amid the advance for preservation of experience, the connotation of fermented Chinese medicine has been enriched and improved. However, fermented Chinese medicine prescriptions generally contain a lot of medicinals. The fermentation process is complicated and the conventional fermentation conditions fail to be strictly controlled. In addition, the judgment of the fermentation end point is highly subjective. As a result, quality of fermented Chinese medicine is of great difference among regions and unstable. At the moment, the quality standards of fermented Chinese medicine are generally outdated and different among regions, with simple quality control methods and lacking objective safe fermentation-specific evaluation indictors. It is difficult to comprehensively evaluate and control the quality of fermented medicine. These problems have aroused concern in the industry and also affected the clinical application of fermented Chinese medicine. This article summarized and analyzed the application, quality standards, and the modernization of fermentation technology and quality control methods of fermented Chinese medicine and proposed suggestions for improving the quality standards of the medicine, with a view to improving the overall quality of it.
