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.

As the body ages， the immune system will undergo a series of changes， which are termed "immunosenescence" and are embodied in immune cells. Previous studies have shown that the immune cells involved in the regulation of immunosenescence include intrinsic immune cells and adaptive immune cells. Intrinsic immune cells are neutrophils， monocytes/macrophages， myeloid-derived suppressor cells， dendritic cells， natural killer cells， etc.， and the underlying mechanisms involve the regulation of cell number， phagocytosis， chemotaxis， adhesion， the function of toll-like receptor （TLR）， antigen presentation， macrophage polarization， cytotoxicity， migration， etc. The adaptive immune cells include T-lymphocytes and B-lymphocytes， and the underlying mechanisms involve the regulation of cell development， proliferation， differentiation， cell number， telomerase activity， self-reactive antibodies， etc. Immunosenescence is the manifestation of aging in the human body and is also an important target for delaying aging by Chinese medicine and western medicine. In recent years， scholars have found some classical prescriptions and their active components （such as Dushentang and total saponins in Panax ginseng leaves， and Shengmaiyin and anwulignan and total saponins in P. ginseng stems and leaves） can regulate immunosenescence by targeting the immune cells and interfering with their molecular regulatory mechanisms. In addition， the mechanisms of the classical prescriptions in regulating immunosenescence are closely related to autophagy. The representative prescription embodying the therapeutic principles of resolving blood stasis and promoting regeneration， Dahuang Zhechongwan， can delay D-galactose-induced renal aging in mice， and its underlying mechanisms are related to the regulation of the number and activity of thymic immune cells and improvement of the protein expression of autophagy-related markers and inflammatory cytokines in the kidney. Therefore， exploring the effects of the classical prescriptions and their active components by targeting the mechanisms of immunosenescence will become a new direction for investigating and developing anti-aging drugs.

The mammalian epididymis not only plays a fundamental role in the maturation of spermatozoa, but also provides protection against various stressors. The foremost among these is the threat posed by oxidative stress, which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids, proteins, and nucleic acids. In mice, the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5 (GPX5) as a major luminal scavenger in the proximal caput epididymidal segment. Accordingly, the loss of GPX5-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx5

The structural equation model showed that received nursing care service (main effect = 0.646) and received rehabilitation services (included nursing care) (main effect = 0.014), age (main effect = 0.031), household registration (main effect = 0.015) and educational level (main effect = -0.158) had effects on unmet needs of nursing care (P < 0.001). Conclusion:Adults with extremely severe and severe intellectual disabilities reported unmet needs mainly involved in field of nursing care, and their rehabilitation services mapped to their main needs. It proposed to develop rehabilitation services tailored to their rehabilitation experience, age, socioeconomic status, functional conditions and characteristic of unmet needs, to develop accessible services items and individualized nursing care programs, and to expand the nursing care service supply and coverage of nursing care.

OBJECTIVETo investigate the association between rs9722 polymorphisms in the S100B gene and hand, foot and mouth disease (HFMD) caused by enterovirus 71.

METHODSA total of 124 HFMD children with enterovirus 71 infection were enrolled as subjects, and 56 healthy children were enrolled as control group. The rs9722 polymorphisms in the S100B gene were detected for both groups, and the serum level of S100B protein was measured for 74 HFMD children.

RESULTSThe rs9722 locus of the S100B gene had three genotypes, CC, CT, and TT, and the genotype frequencies were in accordance with Hardy-Weinberg equilibrium. Compared with the control group, the HFMD group had significant increases in the frequencies of TT genotype and T allele (P<0.01). Children with severe HFMD caused by enterovirus 71 infection had significantly higher frequencies of TT genotype and T allele than those with moderate or mild HFMD (P<0.05). Compared with the cured patients, the patients with poor prognosis had significant increases in the frequencies of TT genotype and T allele in the rs9722 locus of the S100B gene (P<0.05). Among the 74 children with HFMD, the children with TT genotype had the highest serum level of S100B protein, and those with CC genotype had the lowest level (P<0.01).

CONCLUSIONST allele in the rs9722 locus of the S100B gene might be a risk factor for severe HFMD caused by enterovirus 71 infection.

Internal carotid arterial system is the main source of blood supply in brain. In forensic identi-fication practice, blunt injures of internal carotid arterial system usually cause complications such as throm-bus, aneurysm and arteriovenous fistula, etc. The deaths following delayed cerebral infarction or intracra-nial haemorrhage are not rare. At present, literature of deaths caused by blunt injuries of internal carotid arterial system mainly consist of case reports in China. This paper reviews related literature and case re-ports at home and abroad, and summarizes forensic medical features and identification method of the deaths caused by such injuries. The results show that blunt injures of internal carotid arterial system are related to the direct or indirect force on head and neck, which can result in exceed physiological range traction of head and neck, incision following basicranial fracture, etc. Such injuries are common in the cases as mechanical asphyxia, cervical manipulation, traffic accident and fall, etc. The artery should be examined carefully, and the relationship among injury, disease and death should be analysed correctly when no cause of infarction and hemorrhage was found in routine examination of such cases in forensic pratice. Because of the difficulty for exposing the artery completely in autopsy, angiography can be used to infer the location when necessary for improving the scientificity and reliability of the appraisal conclusion.
