Suggestions were thus put forward for their solution.

In current study, we aimed to investigate whether the gentiopicroside (GPS) derived from Gentiana manshurica Kitagawa could block the progression of alcoholic hepatic steatosis to fibrosis induced by chronic ethanol intake. C57BL/6 mice were fed an ethanol- containing Lieber-DeCarli diet for 4 weeks. LX-2 human hepatic stellate cells were treated with GPS 1 h prior to transforming growth factor-β (TGF-β) stimulation, and murine hepatocyte AML12 cells were pretreated by GPS 1 h prior to ethanol treatment. GPS inhibited the expression of type I collagen (collagen I), α-smooth muscle actin (α-SMA) and tissue inhibitor of metal protease 1 in ethanol-fed mouse livers with mild fibrosis. In addition, the imbalanced lipid metabolism induced by chronic ethanol-feeding was ameliorated by GPS pretreatment, characterized by the modulation of lipid accumulation. Consistently, GPS inhibited the expression of collagen I and α-SMA in LX-2 cells stimulated by TGF-β. Inhibition of lipid synthesis and promotion of oxidation by GPS were also confirmed in ethanol-treated AML12 cells. GPS could prevent hepatic steatosis advancing to the inception of a mild fibrosis caused by chronic alcohol exposure, suggesting GPS might be a promising therapy for targeting the early stage of alcoholic liver disease.

Pogostemon cablin is a famous southern medicine.As the important raw material for modern medicine and industry,Pogostemon cablin becomes required with a large marketing demand.However,due to the serious continuous cropping obstacles in the growth process of Pogostemon cablin,the aggravation of diseases of Pogostemon cablin and the degradation of its quality arose.This paper outlined the ecological factors such as climate factors,soil factors and topographic factors suitable for the growth of Pogostemon cablin,analyzed the continuous cropping obstacles and diseases arising in the cultivation,reviewed the current ecological planting mode of Pogostemon cablin such as crop rotation,intercropping,relay-cropping and under-forest planting,and also made a comprehensive evaluation of the economic benefits,ecological benefits and social benefits of the ecological planting mode of Pogostemon cablin,aiming to provide a theoretical basis and a reference for the promotion of the ecological planting mode of Pogostemon cablin.

OBJECTIVETo ascertain the causation of a family cluster involving two undefined pneumonia cases, a 12-year-old girl and her brother, reported October, 2005 in Xiangtan county, Hunan province.

METHODSInformation on epidemiology and clinical manifestation of the cases was collected from interviewing the keyman and referring to related medical records. The environment exposure of the cases to their households and the timeline of the illness were reproduced, using this information. Medical check-up was undergone among the close contacts of the cases and on sick/dead poultry. Throat swab of the cases were collected and tested by both RT-PCR and real-time PCR to detect viral nucleic acids of A/H5N1, and were then inoculated into special pathogen free (SPF) embryonated hens' eggs. Serum of the cases including acute and convalescent phases were also collected and tested by microneutralization and haemagglutination-inhibition (HI) assays to detect H5-specific antibodies.

RESULTSBoth the girl and her brother developed fever 2 and 4 days after sudden deaths of chickens being raised in the same house. Both of them had developed pneumonia and the girl died from acute respiratory distress syndrome (ARDS) complicated with multi-organ failure. The boy survived and subsequently discharged from hospital. An eighth-day serum from the girl tested H5 antibody negative, while 4-fold and greater increased in antibody titers were detected in serum from the boy using microneutralization and HI assays in sequential acute and convalescent sera. Of 192 cases, only one doctor who cared for the girl during hospitalization had upper respiratory symptoms but tested negative for H5N1 by microneutralization assay.

CONCLUSIONThe boy was the first confirmed human case of avian influenza A (H5N1) in the mainland of China and his sister was diagnosed clinically. The most probable explanation of these two cases was that the transmission of H5N1 virus from infected poultry within the same household environment. No evidence of human-to-human transmission was noted in the family cluster.

OBJECTIVE: To summarize the clinical characteristics of patients misdiagnosed with IgG4-related disease, to analyze the reasons of misdiagnosis and to improve the clinical recognition of the disease. METHODS: The general data, clinical manifestations, laboratory examination results and pathological features of 17 patients with IgG4-related diseases misdiagnosed outside the hospital were retrospectively analyzed. RESULTS: Among the 17 patients, there were 9 males and 8 females with a median age of 45 years, and the median time from onset to diagnosis was 12 months. Most patients' initial admission department was not rheumatology or immunology department. Six of the 17 patients were eventually diagnosed with lymphoproliferative disease, 4 with autoimmune disease, and 2 with infectious disease, Rosai Doffman disease, desmofibromatosis, highly differentiated mucoepidermoid carcinoma of the bottom of the mouth, hypereosinophilic syndrome, asthma and allergic rhinitis in 1 case each. The typical sites of IgG4-related disease were involved in 14 patients, including 6 cases of parotid gland, 2 cases of submandibular gland, 3 cases of pancreas and 2 cases of retroperitoneal lesions. Serum IgG4 was elevated in 10 patients, serum IgG4/IgG value was higher than 10% in 7 patients, serum IgE was increased in 7 patients, complement was decreased in 4 patients, and eosinophilic granulocytes were increased in 3 patients. Pathological biopsy was performed in 15 patients, and infiltration of lymphocyte was observed in 10 patients, IgG4+ plasma cells were present in 5 patients, the ratio of IgG4+ plasma cells to IgG+ plasma cells was less than 40% in 4 patients and greater than 40% in 1 patient. However, none of the 15 patients had the storiform pattern of fibrosis and obliterative phlebitis. CONCLUSION A variety of diseases can perform as IgG4-related disease witih typical sites involved, elevated serum IgG4, even can be characterized by pathological IgG4+ plasma cells infiltration. Physicians should pay attention to the differential diagnosis and comprehensively evaluate the patient's clinical manifestations, and laboratory results. Timely and even repeated pathological biopsy is also needed for definite diagnosis.

Since the emergence of the term "materia medica", scholars have proposed different opinions on its concept. This term has been used to refer to traditional Chinese medicines, or medical books, or traditional pharmacology. Due to the differences in the concept of materia medica, scholars also have controversies about the concept of herbalism. Herbalism is usually understood as traditional Chinese pharmacology. After years of evolution, the term "herbalism" has now possessed the characteristics of an independent discipline, which can be defined as an applied basic discipline that comprehensively utilizes traditional and modern technological methods to study the formation, development, and changes of traditional pharmacology and reveal the basic theories and application laws of traditional medicine. At present, the research content of herbalism mainly includes three aspects: materia medica history, materia medica literature, and traditional pharmacology. This study explores the disciplinary concepts and main research content of herbalism based on a systematic review of the literature about the concepts of materia medica and herbalism, with the aim of attracting more attention to promote the establishment and development of the discipline of herbalism.
