ABSTRACT
As a retrovirus with high recombination and mutation rate， HIV targets CD4+ T lymphocytes， causing damage to the body's immune system and eventually leading to severe immune function defects. Different subtypes of the HIV virus exhibit significant sequence differences in their structural and regulatory genes， and this diversity is closely related to etiology， transmission， diagnosis， drug therapy， disease progression， and vaccine development. As a country with the largest number of HIV subtypes， rapid and accurate typing of the HIV virus holds great significance for China's efforts in disease prevention and control. This study provides a comprehensive reveiw of domestic and international HIV genotyping methods， and summarizes the clinical significance of different subtypes in order to provide reference for further research.

ABSTRACT
Gait is a behavioral characteristic of human walking. The formation mechanism of gait is complex and involves multiple organ systems throughout the body, so there are many factors that affect it. Many factors, such as genetics, diseases and accidental injuries, can change a certain link in the walking cycle, leading to changes in gait and abnormal gait. Accurate assessment of abnormal gait can help diagnose the disease, determine the severity of the disease, predict symptom improvement and future functional status, plan appropriate treatment targets, and monitor the effectiveness of interventions. This paper reviews the gait assessment methods commonly used in neurology, including qualitative gait assessment, scale assessment and instrumentalized gait assessment, in order to improve medical staff′s understanding and application ability of common gait assessment methods.
ABSTRACT
Damage to sperm DNA was proposed to play an important role in embryonic development. Previous studies focused on outcomes after fresh embryo transfer, whereas this study investigated the influence of sperm DNA fragmentation index (DFI) on laboratory and clinical outcomes after frozen embryo transfer (FET). This retrospective study examined 381 couples using cleavage-stage FET. Sperm used for intracytoplasmic sperm injection (ICSI) or in vitro fertilization (IVF) underwent density gradient centrifugation and swim up processing. Sperm DFI had a negative correlation with sperm motility (r = -0.640, P < 0.01), sperm concentration (r = -0.289, P < 0.01), and fertilization rate of IVF cycles (r = -0.247, P < 0.01). Sperm DFI examined before and after density gradient centrifugation/swim up processing was markedly decreased after processing (17.1% vs 2.4%, P < 0.01; 65 randomly picked couples). Sperm progressive motility was significantly reduced in high DFI group compared with low DFI group for both IVF and ICSI (IVF: 46.9% ± 12.4% vs 38.5% ± 12.6%, respectively; ICSI: 37.6% ± 14.1% vs 22.3% ± 17.8%, respectively; both P < 0.01). The fertilization rate was significantly lower in high ( ≥25%) DFI group compared with low (<25%) DFI group using IVF (73.3% ± 23.9% vs 53.2% ± 33.6%, respectively; P < 0.01) but was equivalent in high and low DFI groups using ICSI. Embryonic development and clinical outcomes after FET were equivalent for low and high DFI groups using ICSI or IVF. In this study, sperm DFI did not provide sufficient information regarding embryo development or clinical outcomes for infertile couples using FET.

ABSTRACT
Perilla frutescens is a traditional medicinal and edible plant widely distributed in China and enjoys an extensive usage. P. frutescens contains multiple essential oils， which are composed of monoterpenes， sesquiterpenes， and their oxygen-containing derivatives. Compared with other parts of P. frutescens， Perillae Folium produce more oils， with volatile oils as the main constituents. There are many active substances in the volatile oils from Perillae Folium， mainly including perillaldehyde， perillaketone， perillaalcohol， D-limonene， β-caryophylene， etc. Such factors as germplasm， growth environment， extraction method， cultivation time， and harvest period all can trigger changes in volatile oil constituents and content from Perillae Folium. The volatile oils from Perillae Folium have diverse pharmacological effects like anti-oxidation， anti-bacteria， anti-inflammation， vasodilation， anti-tumor， and anti-depression， implying its high clinical application value. However， the chemical constituents in volatile oils from Perillae Folium are complex and unstable and their pharmacological activities are affected by many factors， so the safety and effectiveness of clinical medication fail to be guaranteed， which may has impeded the rational and effective use of these volatile oils. Many scholars in China and abroad have conducted a lot of research on the volatile oils from Perillae Folium， but there is currently no systematic and comprehensive research report on the chemical constituents of volatile oils from Perillae Folium and their pharmacological effects. This paper reviewed the relevant domestic and foreign literature， analyzed the development status of volatile oils from Perillae Folium， and summarized their extraction process， chemical constituents， and pharmacological actions， aiming to provide a reference for their further development， clinical application， and risk assessment.
ABSTRACT
Objective:To investigate the correlation between Traditional Chinese medicine (TCM) constitution classification and clopidogrel-related CYP2C19 gene polymorphism of acute cerebral infarction patients.Methods:A cross-sectional method was used in this study. Patients with acute cerebral infarction were screened and enrolled according to our inclusion and exclusion criteria. TCM constitution were evaluated in patients with acute cerebral infarction. Digital fluorescence hybridization Technology was used to test genotypes of CYP2C19 and Hardy-Weinberg’s equilibrium was used to examine CYP2C19 gene polymorphism of the patients. Binary logistic regression analysis method was used to explore the relationship between TCM constitution types and clopidogrel-related CYP2C19 gene polymorphism in acute cerebral infarction.Results:Among the 100 patients with acute cerebral infarction, 18 belong to Yang-deficiency constitution (18 cases, 18%), 30 Yin-deficiency (30 cases, 30%), 18 belong to Qi-deficiency constitution (18 cases, 18%), 51 belong to phlegm-dampness constitution(51 cases, 51%), 14 belong to damp-heat constitution (14 cases, 14%), 2 belong to special constitution (2 cases, 2%), blood-stasis constitution (27 cases, 27%), Qi stagnation constitution (4 cases, 4%), and normal constitution (11 cases, 11%). The CYP2C19*2 gene polymorphism distribution: CYP2C19*2 (A/A, mutant homozygous) (21 cases, 21%), CYP2C19*2 (A/G, mutant heterozygote) (33 cases, 33%), CYP2C19*2 (G/G) (normal homozygous) (46 cases, 46%). The mutant allele frequency was 0.375. Binary logistic regression analysis showed that compared with A/A genotype, the G/G genotype of CYP2C19*2 in acute cerebral infarction was correlated with phlegm-dampness constitution ( OR=5.105, 95% CI: 1.308-19.928, P<0.05) and blood-stasis constitution ( OR=12.557, 95% CI: 1.741-90.558, P<0.05). Conclusions:The proportion of phlegm-dampness constitution is the highest in patients with acute cerebral infarction. The mutation rate of clopidogrel-related CYP2C19*2 was significantly higher than that of CYP2C19*3 clopidogrel-related CYP2C19*2 gene polymorphism might be related to phlegm-dampness constitution and blood-stasis constitution.
ABSTRACT
BACKGROUND: Bone marrow failure is an important pathogenesis of aplastic anemia, and how to reverse bone marrow failure is an issue of concern. OBJECTIVE: To investigate the regulatory effect of angelica polysaccharide on the mitochondrial dysfunction in murine aplastic anemia. METHODS: Seventy-two ICR mice were randomly divided into control, model and treatment groups (n=24 per group). The mice in the latter two groups were used to establish the aplastic anemia models by60Co γ radiation, intraperitoneal injection of cyclophosphamide and intragastric administration of chloramphenicol, and were then given normal saline or 200 mg/kg angelica polysaccharide for 2 weeks, respectively. The control mice received no intervention. At 1, 7 and 14 days after modeling, peripheral blood cells and bone marrow mononuclear cells were counted, and mitochondrial ultrastructure of the bone marrow was observed by transmission electron microscopy. After Lin- Sca-1+ c-Kit+ (LSK) cells were sorted from bone marrow cells, which were hematopoietic stem cells. The mitochondrial membrane potential, levels of reactive oxygen species, and the expression levels of Bcl 2, Bax, cleaved caspase-9, cleaved caspase-3 and p38 in LSK cells were detected. RESULTS AND CONCLUSION: Compared with the control group, in the model and treatment groups, there were obvious abnormalities in the peripheral blood routine test was the number of bone marrow mononuclear cells was decreased significantly, the mitochondrial number, mitochondrial membrane potential and Bcl 2/Bax ratio were decreased, and the level of reactive oxygen species and the expression of cleaved caspase-9, cleaved caspase-3 and p38 in LSK cells were significantly increased (P < 0.05). After angelica polysaccharide treatment, all above results were significantly improved as compared with the model group (P < 0.05). To conclude, angelica polysaccharide might improve hematopoietic function by up-regulating the mitochondrial membrane potential, increasing the mitochondrial membrane stability and reversing the levels of apoptotic factors.

ABSTRACT
Neuropilins (NRP1 and NRP2) are multifunctional receptor proteins that are involved in nerve, blood vessel, and tumor development. NRP1 was first found to be expressed in neurons, but subsequent studies have demonstrated its surface expression in cells from the endothelium and lymph nodes. NRP1 has been demonstrated to be involved in the occurrence and development of a variety of cancers. NRP1 interacts with various cytokines, such as vascular endothelial growth factor family and its receptor and transforming growth factor β1 and its receptor, to affect tumor angiogenesis, tumor proliferation, and migration. In addition, NRP1+ regulatory T cells (Tregs) play an inhibitory role in tumor immunity. High numbers of NRP1+ Tregs were associated with cancer prognosis. Targeting NRP1 has shown promise, and antagonists against NRP1 have had therapeutic efficacy in preliminary clinical studies. NRP1 treatment modalities using nanomaterials, targeted drugs, oncolytic viruses, and radio-chemotherapy have gradually been developed. Hence, we reviewed the use of NRP1 in the context of tumorigenesis, progression, and treatment.

ABSTRACT
Objective To investigate the infection status of intestinal nematodes and their risk factors in rural residents of Jiangxia District, Wuhan City, so as to provide the reference for the establishment of targeted prevention and control measures. Methods According to the requirements of cross-sectional study of the national human key parasitic diseases, the residents in Shanpo Sub-district, Jiangxia District were randomly selected as the objects for the investigation of the infection status of Ascaris lumbricoides, hookworm and Trichuris trichiura. A questionnaire survey was performed simultaneously. Results Totally 236 residents received the stool tests, and only the hookworm eggs were found, with an infection rate of 7.63% (18 cases). The survey of intestinal parasitic infection status and their risk factors in 600 residents found 397 cases of suspected roundworm infection, 355 cases of suspected hookworm larvae dermatitis, 295 cases of suspected hookworm infection, and 145 cases of suspected whipworm infection, respectively. The Logistic regression analysis found that the risk factors of suspected roundworm infection included not always washing hands after toilet, using manure and fertilizer, and not often wearing shoes when doing farm work; the protective factors included knowing how roundworm infection was gained, and not using fresh dung for fertilization. The risk factors of suspected hookworm infection included using well water and pond water as the source of drinking water, eating food off the ground, using manure and fertilizers, and not washing when there was only one cutting board, and its protective factors included using tap water and well water as drinking water source, knowing how the roundworm infection was gained, and sometimes or not suing fresh feces for fertilization. The risk factors for suspected whipworm infection included eating food off the ground. Conclusions The intestinal parasite prevalence in the residents of the Shanpo Sub-district, Jiangxia District in Wuhan City is relatively high, and some risk factors associated with their infection indeed exist. Therefore, the regional government and health department should strengthen the health education to improve the residents’ knowledge about parasitic diseases and selfprotection awareness. At the same time, the residents should take physical examination regularly and take necessary deworming treatment to effectively control the prevalence and spread of intestinal parasitic diseases.
