Abstract
Large numbers of unique recombinant forms (URF) of human immunodeficiency virus (HIV-1) have been found among sexual transmission populations in China. Here, we report a novel second-generation URF of HIV-1 named BD201AQ that was isolated from an HIV-1-positive man who was infected through homosexual transmission in Baoding City, Hebei Province, China. Phylogenetic analysis based on the near-full-length genome (NFLG) sequence indicated that BD201AQ formed a monophyletic branch that did not cluster with other HIV-1 subtypes. Recombination analysis showed that the NFLG of BD201AQ had 12 segments, six CRF07_BC and six CRF01_AE segments, with CRF07_BC as the main framework. These findings indicate that the constant emergence of novel recombinant forms should receive more attention and that more measures should be taken to monitor the molecular epidemiological characteristics of HIV-1 and to prevent the spread of HIV-1 infections.

Abstract
We report in this study a novel HIV-1 second-generation recombinant form (TJIH0172) composed of CRF01_AE and CRF07_BC isolated from a married HIV-positive male subject infected through homosexual behavior in Tianjin, China. The phylogenetic analysis of the near full-length genome of TJIH0172 reveals that one region of CRF07_BC inserted into the CRF01_AE backbone with two recombinant breakpoints observed in the vpu and env gene regions, respectively. The CRF01_AE regions (the regions I and III) of the recombinant are greatly clustered with the CRF01_AE subcluster 4 lineage, which is mainly circulating among men who have sex with men (MSM) in northern China. The CRF07_BC region (II) is clustered with two sequences (JX960600 and KF250366), which were discovered in the MSM population in Liaoning Province and Beijing city in northern China, respectively. The emergence of the novel recombinant strain from a married man who has sex with men in Tianjin, China, highlights the increasing complexity of the HIV-1 epidemic between MSM and their female partners and further molecular epidemiological investigation should be taken to track married MSM and their female partners to prevent HIV transmit from HIV high-risk populations to general populations.

Abstract
We report here a novel human immunodeficiency virus type 1 (HIV-1) second-generation recombinant form comprising CRF01_AE and CRF07_BC isolated from an HIV-positive male subject infected among men who have sex with men (MSM) in Tianjin in north China. The phylogenetic analysis of the near full-length genome of TJIH0345 reveals that three regions of CRF01_AE were inserted into the CRF07_BC backbone with five recombinant breakpoints observed in the pol, vif, vpu, and env gene regions whose genome structure is distinctly different from other circulating recombinant forms and unique recombinant forms previously reported. The continued emergence of the novel recombinant strain in Tianjin, China, highlights the increasing complexity of the HIV-1 epidemic among the MSM population, and further molecular epidemiological investigation should be done to track the genetic evolution of HIV-1 strains to prevent HIV transmission.

Prevalence of HIV-1 Drug Resistance among Patients with Antiretroviral Therapy Failure in Sichuan, China, 2010-2016. TOHOKU J EXP MED 2019; 247:1-12.

Abstract
Antiretroviral therapy (ART) has been introduced recently and has significantly impacted morbidity and mortality, but can also engender drug resistance. To identify the prevalence of HIV-1 drug resistance (HIVDR) among patients with antiretroviral therapy failure in Sichuan during the period from 2010 to 2016, we carried out a longitudinal study in Sichuan, a province with the highest HIV/AIDS prevalence in China. The data and blood samples were collected from HIV/AIDS patients who received ART for more than half a year. Overall 5,512 sequences were completed from 7,059 ART-failure patients, and 2,499 individuals were identified as drug resistant. Among those with HIVDR mutations identified, 25.37% were against non-nucleoside reverse transcriptase inhibitors (NNRTIs), and 1.60% was against nucleoside reverse transcriptase inhibitors (NRTIs). NRTI-resistant drugs were mainly lamivudine (3TC) (57.77%) and emtricitabine (FTC), while NNRTI-resistant drugs were mainly nevirapine (NVP) (91.13%) and efavirenz (EFV) (72.81%). The most common recombination subtypes of HIV-1 in sequenced samples were CRF07_BC (circulating recombinant form, CRF) (41.42%), followed by CRF01_AE (40.77%). Moreover, drug resistance rate increased with the prolongation of treatment time (χ2 = 14.758, P < 0.05). The overall prevalence of acquired drug resistance in HIV-1 infected patients in Sichuan was 5.47%, which has remained relatively stable from 2010 to 2016. HIV-1 CRF01_AE and CRF07_BC subtypes were the main epidemic strains, and the possibility of resistance was higher in CRF01_AE subtypes. The current study highlights the importance of acquired drug resistance surveillance over a long period.
