Analysis of HIV-1 subtypes and pretreatment drug resistance in newly reported HIV/AIDS cases in Hangzhou, 2020-2022 / 中华微生物学和免疫学杂志

Objective:To analyze the HIV-1 subtypes and drug resistance among newly reported HIV/AIDS cases before antiretroviral therapy (ART) in Hangzhou.Methods:Blood samples were collected from newly diagnosed HIV-1/AIDS cases not receiving ART in Hangzhou from 2020 to 2022. HIV-1 pol gene was amplified and then sequenced. A phylogenetic tree was construct using MEGA7.0 software to analyse the HIV-1 subtypes, The sequences were submitted to the Stanford University drug resistance database to identify drug resistance mutation sites and drug sensitivity. Results:A total of 2 700 sequences were obtained. Twelve subtypes were identified, and the predominant subtypes were CRF07_BC (46.8%, 1 263/2 700) and CRF01_AE (34.6%, 933/2 700). The overall drug resistance rate before ART was 8.1% (220/2 700) and the resistance rates to protease inhibitors (PIs), nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) were 2.8% (75/2 700), 1.3% (36/2 700) and 4.4% (119/2 700), respectively. Among the 220 drug-resistant cases, mutations conferring resistance to PIs (Q58E), NRTIs (M184V/I) and NNRTIs (K103N/S and E138A/G/K/Q) were detected in 47 (21.4%), 13 (5.9%), 42 (19.1%) and 41 (18.6%) patients, respectively.Conclusions:HIV-1 genotypes were highly complex in newly reported HIV/AIDS cases in Hangzhou from 2020 to 2022. There were cases showing moderate or high resistance to backbone drugs before ART, indicating that HIV-1 monitoring should be strengthened to avoid treatment failure and reduce the spread of drug-resistant strains.

A new form of familial platelet disorder caused by germline mutations in RUNX1 in a pedigree / 中华内科杂志

Objective: To investigate the clinical and biological characteristics of familial platelet disorder (FPD) with germline Runt-related transcription factor (RUNX) 1 mutations. Methods: Patients diagnosed with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) with RUNX1 mutations from February 2016 to December 2021 in Wuhan No.1 Hospital underwent pedigree analysis and were screened for gene mutations (somatic and germline). Patients diagnosed with FPD with germline RUNX1 mutations were enrolled and evaluated in terms of clinical characteristics and biological evolution. Bioinformatics analysis was used to assess the pathogenicity of mutations and to analyze the effect of mutated genes on the function of the corresponding protein. Results: Germline RUNX1 mutations were detected in three out of 34 patients suffering from MDS/AML who had RUNX1 mutations. A pedigree of FPD with RUNX1 (RUNX1-FPD) c.562A>C and RUNX1 c.1415T>C mutations was diagnosed, and the mutations were of patrilineal origin. Bioinformatics analysis indicated that the locus at positions 188 and 472 in the AML-1G type of RUNX1 was highly conserved across different species, and that variations might influence functions of the proteins. The mutations were evaluated to be highly pathogenic. Of the nine cases with germline RUNX1 mutations: two patients died due AML progression; one case with AML survived without leukemia after transplantation of hemopoietic stem cells; four patients showed mild-to-moderate thrombocytopenia; two cases had no thrombocytopenia. During the disease course of the proband and her son, mutations in RUNX1, NRAS and/or CEBPA and KIT appeared in succession, and expression of cluster of differentiation-7 on tumor cells was enhanced gradually. None of the gene mutations correlated with the tumor were detected in the four cases not suffering from MDS/AML, and they survived until the end of follow-up. Conclusions: RUNX1-FPD was rare. The mutations c.562A>C and c.1415T>C of RUNX1 could be the disease-causing genes for the family with RUNX1-FPD, and these mutations could promote malignant transformation. Biological monitoring should be carried out regularly to aid early intervention for family members with RUNX1-FPD.

A cohort study of incidence of club drug abuse in men who have sex with men in Qingdao / 中华流行病学杂志

Objective: To understand and analyze the incidence of club drug abuse and influencing factors in men who have sex with men (MSM) in Qingdao, and provide reference for the AIDS prevention and intervention in this population. Methods: From March 2017 to July 31, 2022, MSM who did not abuse club drug were recruited by snowball sampling of MSM social organizations in Qingdao, a prospective cohort was established, and a follow-up survey was conducted every 6 months. The survey collected the information about the MSM's demographic characteristics, sexual characteristics, club drug abuse and others. The incidence of club drug abuse was the outcome dependent variable and the interval between the recruitment into the cohort and the incidence of club drug abuse was the time dependent variable. Cox regression analysis was conducted to identify the influencing factors for club drug abuse. Results: A total of 509 MSM were recruited at baseline survey, and 369 eligible MSM were enrolled in this cohort. A total of 62 MSM began to abuse club drug during the study period, and the cumulative follow-up time was 911.54 person-years, the incidence of club drug abuse was 6.80/100 person-years. All the club drug abusers shared drugs with others in the first club drug abuse, and 16.13% (10/62) had mix-use of club drugs. The multivariate Cox proportional risk regression analysis showed that being students (aHR=2.17, 95%CI: 1.15-4.10), receiving no HIV testing or receiving 1 HIV testing during past 6 months (aHR=4.57, 95%CI:1.80-11.60; aHR=5.15, 95%CI: 2.83-9.36), having sex only with regular sexual partners during past 6 months (aHR=4.75,95%CI:2.32-9.75), having more than 4 homosexual partners (aHR=1.70, 95%CI:1.01-2.87) and abuse of club drug of sexual partners during past 6 months (aHR=12.78, 95%CI:3.06-53.35) were significantly associated with club drug abuse in the MSM. Conclusions: The incidence of club drug abuse was at a high level in the MSM cohort in Qingdao, indicating a high risk for HIV infection. Being student, receiving less HIV testing, having sex only with regular sexual partners, having more homosexual partners and abuse of club drug of sexual partners during past 6 months were risk factors for the incidence of club drug abuse in the MSM. Targeted surveillance and intervention measures should be strengthened to reduce the risk of club drug abuse in MSM.

Inhibition of Sonic Hedgehog signaling inhibits fibrous scar formation and adversely affects functional outcome after ischemic brain injury in rats / 南方医科大学学报

OBJECTIVE@#To investigate the effects of inhibiting Sonic Hedgehog (Shh) signaling on fibrous scar formation and functional outcome after ischemic brain injury.@*METHODS@#Adult SD rats were randomized into sham-operated group, middle cerebral artery occlusion (MCAO) and reperfusion (I/R) group, I/R with intraventricular empty adenoviral vector (rAd-NC) injection group, and I/R with adenovirus-mediated Shh knockdown (rAd-ShShh) group. After the treatments, the neurological deficits of the rats were assessed, and the protein and mRNA expressions of fibronectin (Fn), α-SMA, and Shh in the ischemic hemisphere were detected with immunofluorescence assay and qPCR; TUNEL staining was used for detecting neural cell apoptosis. In the cell experiment, primary meningeal fibroblasts isolated from neonatal SD rats were pretreated for 24 h with TGF-β1 or TGF-β1 plus cyclopamine (CYC) before oxygen-glucose deprivation for 150 min followed by reoxygenation for 72 h (OGD/R). CCK-8 assay and scratch test were performed to examine the changes in cell proliferation and migration, and immunofluorescence assay, qPCR and Western blotting were used for detecting cell transformation and the expressions of Shh, α-SMA, and Fn.@*RESULTS@#Cerebral I/R injury significantly increased the protein and mRNA expressions of Shh, α-SMA, and Fn in the ischemic hemisphere of the rats, but their expression levels were significantly lowered by intraventricular injection of rAd-Shshh (P < 0.05), which obviously increased cell apoptosis in the ischemic hemisphere (P < 0.05) and improved modified mNSS and modified Bederson scores of the rats (P < 0.05). In the cell experiment, pretreatment with TGF-β1 and TGF-β1+CYC both increased the viability of the primary meningeal fibroblasts after OGD/R. TGF-β1 significantly enhanced the migration ability and induced obvious transformation of the exposed cells (P < 0.05), but these effects were significantly attenuated by co-treatment with CYC (P < 0.05). The expressions of Shh, α-SMA and Fn in the TGF-β1 group were all significantly higher in TGF-β1-treated cells (P < 0.05) and were obviously lowered by co-treatment with CYC (P < 0.05).@*CONCLUSION@#Inhibition of Shh signaling may inhibit fibrous scar formation and functional recovery in rats after ischemic brain injury.

Effect of Siwutang on Diminished Ovarian Reserve in Rats Based on 16S rRNA Sequencing of Intestinal Flora / 中国实验方剂学杂志

ObjectiveTo study the effect of Siwutang （SWT） on intestinal flora in rats with diminished ovarian reserve （DOR） induced by Tripterygium wilfordii polyglycoside （TWP） based on 16S rRNA sequencing. MethodTwenty 8-week-old female SD rats were randomly assigned into four groups： blank group， model group， SWT high-dose group， and SWT low-dose group. Except the blank group， the other three groups were underwent intragastric administration of TWP tablets at a dose of 50 mg·kg-1 for 14 days. On day 15， the high-dose group was administrated at 3 times of the human dosage （40 g/person/day）， the low-dose group at 1.5 times of the human dosage， and the model group and the blank group with the same volume of normal saline for 18 days. Then， feces were collected for 16S rRNA sequencing. One hour after administration， blood was sampled from abdominal aorta after anesthesia for the measurement of hormone levels by radioimmunoassay， and ovaries were sampled， embedded， sliced， and stained with haematoxylin-eosin （HE） for pathological observation. ResultThe model group had higher level of luteinizing hormone （LH， P<0.05） and lower level of estradiol （E2， P<0.05） than the blank group. The SWT high-dose group and low-dose group had lower LH levels （P<0.05） and higher E2 levels than the model group （P<0.05）. SWT reversed the elevation in follicle-stimulating hormone （FSH） and LH levels and the decline in E2 and progesterone （P） levels caused by TWP to some extent. There were a large number of follicles at different developmental stages in the blank group， while atretic follicles increased significantly in the model group. A large number of mature follicles， secondary follicles， and primary follicles were observed in the high-dose SWT group， and primordial follicles， secondary follicles， and increased corpus luteum in the low-dose SWT group. Compared with that in the blank group and the administration group， the abundance of Verrucomicrobia and Epsilonbacteraeota in the model group significantly reduced. Compared with the blank group， the model group had different intestinal flora in phylum， class， order， family， and genus levels. Specifically， the model group had increased proportions of Firmicutes and Bacteroidetes. After TWP modeling， the abundance of Lachnospiraceae decreased significantly while that of Ruminococcaceae UCG-005 increased significantly. SWT groups， blank group， and model group can be clearly distinguished， and SWT groups had a tendency to approach the blank group. ConclusionSWT may improve the ovarian function of rats with TWP-induced DOR by regulating intestinal flora diversity.

Objective:To explore the expectations and values of patients with malocclusion on participation in shared decision-making of orthognathic surgical protocols, and to provide references for further development of clinical shared decision-making models.Methods:Based on the expected value theory and descriptive qualitative research methods, using purposive sampling, 13 patients with malocclusion in the Ninth People's Hospital of Shanghai Jiao tong University School of Medicine from May to August in 2021 were selected for semi-structured interviews. The interview data were sorted, classified and refined by traditional content analysis.Results:Two themes were extracted: patients' ability beliefs about their ability to participate in shared decision making for orthognathic surgery(decision support ability, psychological coping ability and environmental adaptability), and task values for shared decision making for orthognathic surgery(interest value, acquisition value).Conclusions:Low level of patients′ ability beliefs in shared decision-making, active physician guidance facilitates patient participation, but the depth of patient participation is influenced by factors such as information support, cultural climate, and physical space for shared decision making. It is suggested that the magnetic role of physicians should be actively played, the shared decision-making team should be strengthened, at the same time, hospital manager should enhance shared decision making propaganda to increase the acceptance and participation of patients in shared decision making so as to improve the quality of shared decision-making.

The clinical effects on the salivation of children with cerebral palsy of oral-facial muscle training based on action observation and a virtual environment / 中华物理医学与康复杂志

Objective:To observe the effect of oral-facial muscle training applying virtual reality technology (VR) and of action observation therapy on the salivation of children with cerebral palsy (CP).Methods:Sixty CP children with uncontrolled salivation were randomly divided into a control group and an observation group, each of 30. In addition to conventional rehabilitation treatment, the control group received routine tongue muscle training, buccal lip muscle training, ice stimulation, and Masako swallowing training. The observation group received oral-facial muscle training based on action observation therapy in a virtual environment. Both groups were trained 30min per day, 5 times a week for 3 weeks. Before and after the treatment, drooling (DDSS) and swallowing function scores were evaluated. Integrated surface electromyography (iEMG) of the buccinator and orbicularis oris muscles was also performed.Results:After treatment, a significant decrease was observed in the average DDSS and the swallowing function scores of both the control and observation groups, along with a significant increase in the average root mean square values of the buccinator and orbicularis oris iEMGs of both groups. However, the average DDSS score of the observation group was significantly lower than that of the control group, while the average iEMG readings were significantly better.Conclusion:VR-based action observation oral-facial muscle training is a more effective supplement to conventional rehabilitation treatment than conventional oral-facial muscle training in improving the salivation of children with CP.

Immune-related myositis induced by immune checkpoint inhibitors: two case reports and literature review / 中华风湿病学杂志

Objective:To investigate the clinical features and treatment status of immune-related myositis (IRM) caused by immune checkpoint inhibitors (ICIs) in order to improve the diagnosis and treatment rate of the disease.Methods:Two cases of IRM combined with the diagnosis and treatment were described and the literature about IRM in the past 10 years was reviewed, and the clinical data of 59 patients were analyzed.Results:IRM was more common in males, with a total of 47 (79.7%). IRM usually occurred after 45 days of medication or after two doses. The clinical manifestations were mainly myalgia and muscle weakness, which were more common in the limbs. The initial symptoms were ptosis and diplopia. Fifty patients (84.7%) had serum creatine kinase (CK) levels higher than twice the upper limit of normal (UNL). In immunological examinations, 18 patients were found to be positive for anti-rhabdoid muscle antibody (AsM-Ab), while most of the myositisspecific antibodies (MSAs) and myositis-associated antibodies (MAAs) were negative. Thirty-four patients (75.6%) had abnormal EMG, and most patients showed myogenic injury. Muscle magnetic resonance imaging (MRI) showed muscle edema and inflammation in 8 patients. Muscle biopsies from 18 (45.0%) patients showed varying degrees of necrotic myofibers. Fifty-seven patients (96.6%) discontinued ICIs after developing IRM, 54(91.5%) received cortico-steroids, and 20(33.9%) received other treatments including intravenous immuno-globulin (IVIG), plasma exchange.Conclusion:IRM can occur in the early stage of ICIs treatment. Electro-myography, muscle MRI and muscle biopsy in suspicious cases can improve the diagnosis rate of the disease. Early use of corticoteroid, IVIG and other immunotherapy can effectively alleviate the disease.

Research progress on the role of microRNAs in diabetic retinopathy / 国际眼科杂志(Guoji Yanke Zazhi)

@#The microRNAs(miRNAs)is a non-coding small RNA molecule with the function of regulating gene expression, which can be released by cells and tissues in various biological fluids, including serum or plasma. A large number of studies have confirmed that the expression of different miRNAs in diabetic retinopathy(DR)can be specifically increased or decreased. Recently, more and more evidence shows that some miRNAs in serum and plasma are specifically expressed in DR and participate in the occurrence and development of DR, and can become biomarkers for the diagnosis of DR and monitoring of DR progress. In addition, the regulation of these miRNAs levels may delay the progression of DR for early intervention in patients with DR. miRNAs is expected to become a new therapeutic target for DR. This paper mainly reviews the progress of miRNAs in the diagnosis and monitoring of DR and possible new therapeutic targets in recent years.

@#Brain-derived neurotrophic factor(BDNF)is a basic protein, and a member of neurotrophic factor family, which plays an important role in the development, differentiation and maintenance of neurons. A large number of studies have confirmed that BDNF is involved in the occurrence and development of neurodegenerative diseases such as Parkinson's disease and Alheimer's disease, and has a neuroprotective effect. In the retina, BDNF is mainly produced by retinal ganglion cells, amacrine cells, astrocytes, retinal glial cells(Müller cells)and photoreceptors. In recent years, related studies have found that BDNF is involved in the occurrence and development of glaucoma, diabetic retinopathy(DR)and other ocular diseases, and may have a diagnostic role, which will be beneficial to early intervention of patients to avoid the development of advanced glaucoma or DR. On the other hand, BDNF-based therapies have achieved good results in <i>in vitro</i> and <i>in vivo</i> experiments of glaucoma, DR and amblyopia, which may provide more choices for the treatment of these ocular diseases. In this manuscript, the research progresses of BDNF in ocular diseases in recent years were reviewed.
