Objective:To analyze the variation characteristics of gag gene sequence of human immunodeficiency virus type 1 (HIV-1) epidemic strains in four major acquired immunodeficiency syndrome (AIDS) endemic areas in Yunnan Province. Methods:A total of 480 human immunodeficiency virus (HIV)/AIDS patients from designated antiviral treatment institutions in Kunming City, Dehong Dai and Jingpo Autonomous Prefecture, Hani-Yi Autonomous Prefecture of Honghe and Lincang City in Yunnan Province from January 2019 to December 2020 were randomly selected. The epidemiological information of the patients was collected. The plasma samples were collected and sent to the Yunnan Provincial Infectious Diseases Hospital for analysis. HIV-1 gag gene was amplified by nested polymerase chain reaction for genotyping.The phylogenetic tree was constructed by MEGA 6.06, and the characteristic amino acids were analyzed by VESPA online analysis tool. The gene distances of gag and matrix protein p17, capsid protein p24, nucleocapsid protein p7 and p6 protein of gag protein were calculated by Distance program. The ratio of synonymous mutation frequnency and non-synonymous mutation frequnency (Ks/Ka) was analyzed by SNAP program. Statistical comparison among multiple groups was performed using analysis of variance. Results:The gag gene sequences were successfully obtained from 404 patients.Most of these patients were men (250 cases, 61.9%), 59.7%(241/404) of patients were aged 40 to 59 years, and the main transmission route was heterosexual transmission (61.4%, 248/404). The main epidemic subtypes of HIV-1 were circulating recombinant form(CRF)08_BC (38.4%, 155/404), CRF01_AE (18.3%, 74/404), unique recombinant form (URF) (12.9%, 52/404), CRF07_BC(9.7%, 39/404), C subtype (8.4%, 34/404), other subtypes (6.9%, 28/404) and B subtype (5.4%, 22/404). Two main spreading clusters were formed by CRF08_BC in the phylogenetic tree, and there were significant differences in the distribution of characteristic amino acids of eight loci between the two spreading clusters, including No.79, 93, 121, 122, 151, 363, 395 and 396. The gag gene distances of CRF01_ AE, CRF07_ BC and CRF08_ BC were 0.090±0.004, 0.088±0.004 and 0.078±0.002, respectively, and the difference was statistically significant ( F=118.33, P<0.001). The Ks/Ka values of gag of the three subtypes were 4.003±1.309, 4.141±0.860 and 4.514±1.215, respectively, and the difference was statistically significant ( F=1.35, P<0.001). The Ks/Ka values of p17 were 2.590±0.186, 2.831±0.496 and 2.936±0.475, respectively, and the difference was statistically significant ( F=1.59, P<0.001). The Ks/Ka values of p24 were 12.579±1.116, 10.185±0.494 and 8.522±0.595, respectively, and the difference was statistically significant ( F=1.61, P<0.001). The Ks/Ka values of p7 were 10.850±0.711, 9.717±0.932 and 8.522±0.026, respectively, and the difference was statistically significant ( F=4.24, P<0.001). The Ks/Ka values of p6 were 3.122±0.134, 3.040±1.498 and 4.841±0.353, respectively, and the difference was statistically significant ( F=10.68, P<0.001). Conclusions:CRF08_ BC is the main subtype in these four areas in Yunnan Province.The different clusters of CRF08_BC result in a different pattern of amino acid composition.The variation degree of different subtype gag gene is different in each section. Surveillance of HIV variant strains should be strengthened to control the epidemics of HIV.

ObjectiveTo investigate the possible mechanism of Wenfei Huaxian Decoction (温肺化纤汤) in treatment of pulmonary fibrosis in systemic sclerosis-associated interstitial lung disease (SSc-ILD). MethodsSixty C3H/He female rats were randomly divided into a control group, a model group, a pirfenidone group, and low-, medium-, and high-dose Wenfei Huaxian Decoction groups. The SSc-ILD model mice was established by subcutaneous injection of bleomycin solution 0.04 mg/d into the back of mice for 28 days in all groups but the control group. After successful modelling, the pirfenidone group was given pirfenidone capsule 300 mg/(kg·d) by gavage, the low-, medium- and high-dose Wenfei Huaxian Decoction groups were given Wenfei Huaxian Decoction 7.81, 15.62, and 31.24 g/(kg·d) by gavage, respectively, and the control group as well as the model group were given normal saline 0.1 ml/10 g by gavage, for a total of 21 days. At the end of the intervention, HE staining and Masson staining were used to observe the pathological changes in the skin and lung tissues; the hydroxyproline content of the skin and lung tissues was detected; the protein expression levels of endoplasmic reticulum stress-related proteins glucose-regulated protein 78 (BIP) and C/EBP homologous protein (CHOP) as well as those of nuclear factor kappa B (NF-κB) pathway p65 were measured by western blot; ELISA was performed to determine the expression levels of interferon gamma (IFN-γ), interleukin 6 (IL-6) and tumour necrosis factor alpha (TNF-α) in serum of rats. ResultsThe results of HE and Masson staining indicated that compared with the control group, the dermis significantly thickened, the number of collagen fibers significantly enlarged, and the number of inflammatory cells significantly increased in the model group; the lung tissue showed a marked inflammatory cellular response with massive collagen fibre proliferation with inflammatory cell infiltration. Compared with the model group, the skin tissue and lung tissue collagen fibre proliferation significantly reduced and inflammatory cell infiltration reduced in the pirfenidone group and all dose groups of Wenfei Huaxian Decoction, and the effects of pirfenidone group and Wenfei Huaxian Decoction medium- and high-dose groups were basically comparable. Compared with the model group, the content of hydroxyproline in skin and lung tissue, the serum level of IFN-γ, IL-6 and TNF-α, and the expression levels of BIP and CHOP protein in lung tissue increased in model group (P<0.05). Compared with model group, the content of hydroxyproline in skin tissue of pirfenidone group, low-and medium-dose Wenfei Huaxian Decoction groups decreased, and the content of hydroxyproline in lung tissue of medium-dose Wenfei Huaxian Decoction group decreased. The serum level of IFN-γ, IL-6, TNF-α and the expression levels of BIP, CHOP and p65 protein in lung tissue of rats in pirfenidone group and high-dose Wenfei Huaxian Decoction group decreased (P<0.05). The content of hydroxyproline in lung tissue of medium-dose Wenfei Huaxian Decoction group was significantly lower than that of low-dose and high-dose Wenfei Huaxian Decoction group, and the serum level of IFN-γ, IL-6, TNF-α in low- and medium-dose Wenfei Huaxian Decoction group were higher than those in high-dose Wenfei Huaxian Decoction group. The expression level of BIP protein in high-dose group was significantly lower than that in low- and medium-dose Wenfei Huaxian Decoction groups (P<0.05). ConclusionWenfei Huaxian Decoction can improve the skin and lung fibrosis of SSc-ILD rats, which may act through anti-inflammation, inhibition of NF-κB pathway, and then inhibition of endoplasmic reticulum stress, which ultimately blocked the fibrotic process.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

cFos is one of the most widely-studied genes in the field of neuroscience. Currently, there is no systematic database focusing on cFos in neuroscience. We developed a curated database—cFos-ANAB—a cFos-based web tool for exploring activated neurons and associated behaviors in rats and mice, comprising 398 brain nuclei and sub-nuclei, and five associated behaviors: pain, fear, feeding, aggression, and sexual behavior. Direct relationships among behaviors and nuclei (even cell types) under specific stimulating conditions were constructed based on cFos expression profiles extracted from original publications. Moreover, overlapping nuclei and sub-nuclei with potentially complex functions among different associated behaviors were emphasized, leading to results serving as important clues to the development of valid hypotheses for exploring as yet unknown circuits. Using the analysis function of cFos-ANAB, multi-layered pictures of networks and their relationships can quickly be explored depending on users’ purposes. These features provide a useful tool and good reference for early exploration in neuroscience. The cFos-ANAB database is available at www.cfos-db.net.
