Objective To establish a mini-pool nucleic acid testing (NAT) assay using multiplex RT-nested PCR for the detection of HIV RNA, and apply it in screening for acute HIV infection among MSM. Methods Frozen EDTA plasma samples collected between Oct. 2008 and Mar. 2009 from 3 HIV infectors during window-period, a total of 30 HIV chronically infected individuals and 97 healthy subjects were used to develop the NAT assay. Plasma samples from 10 cases were pooled into one tube and centrifuged at high speed for the collection of viruses. HIV RNA was extracted. Two pairs of primers were designed according to two conserved regions of HIV RNA ( HXB2 nt 5783-nt 6228 and nt 1235-nt 2012).Multiplex RT-PCR and nested PCR were performed. Individual NAT-reactive samples were confirmed by commercially available NAT assays. The sensitivity and performance efficacy were also evaluated. The assay was then applied to 1 005 plasma specimens from MSM with negative or uncertain HIV antibody test results.These were collected in the same period as the other samples. Results ( 1 ) Two fragments of HIV were amplified successfully with the low detection limit of 162 copies/ml plasma; (2) Results of the mini-pool HIV NAT validation with samples from 3 HIV infectors during window-period were consistent with the expected values; (3) All 30 plasma samples from MSM with positive HIV antibody, which were tested by multiplex RT nested PCR, were found to be HIV RNA positive; (4) One out of 1 005 plasma samples was found to be HIV RNA positive, for this case acute infection was followed-up and sero-conversion was found. Conclusion Mini-pool NAT has good sensitivity, and may be applied to screening HIV RNA among MSM during window-period.

Background:
and Purpose Most of the knowledge of Mycoplasma pneumonia (M. pneumoniae) encephalitis (MPE) in children is based on case reports or small case series. This study aimed to describe the clinical features and prognostic factors of MPE, and the efficacy of azithromycin with or without immunomodulatory therapy.
Methods:
The medical data of 87 patients with MPE from 3 medical centers in southwestern China over a 7-year period were reviewed.
Results:
MPE was found in children of all ages except for neonates. The most common neurological manifestations included consciousness disturbance (90%) and headache (87.4%), the most common extraneurological manifestations included fever (96.5%) and respiratory system involvement (94.3%); multisystem involvement (98.2%) and elevated C-reactive protein (CRP) (90.8%) were also prominent. M. pneumoniae was detected in cerebrospinal fluid (CSF) less often than in blood and respiratory tract secretions. Azithromycin with intravenous immunoglobulin or/and corticosteroid treatment can shorten the hospitalization duration and the clinical improvement process. Most patients (82.8%) received a favorable prognosis; serum lactate dehydrogenase (LDH) and CSF protein levels were higher in the poor-outcome group than in the good-outcome group (p<0.05). Neurological sequelae are likely to continue when the onset of this condition occurs during teenage years.
Conclusions
MPE generally presented with nonspecific clinical manifestations. In children with acute encephalitis accompanied by multi-system involvement and prominently elevated CRP, M. pneumoniae should be considered as a possible pathogen. Immunomodulating therapies should be recommended regardless of the duration of the prodromal period. High CSF protein

Objective:To explore the efficacy and safety of hyaluronic acid filler VYC-20L for full-face lifting in aesthetic seeking patients.Methods:Between November 2020 and November 2021, a total of 216 aesthetic seeking patients were enrolled in Shanghai Chingho Outpatient Department, World Path Clinic International, Qihe Medical Beauty Hospital and Qinhuangdao Qiaozhi Beauty Hospital, including 37 males and 179 females, aged 25-67 (41.42±10.93) years. According to the needs and requirements, the novel injection technique of " ROYGBbP-rainbow lifting method" was used to inject hyaluronic acid filler VYC-20L. The global aesthetic improvement scale (GAIS) and the treatment satisfaction questionnaires were scored and evaluated before the injection, and at follow-up visits 1, 6, and 12 months after the injection. Any adverse reaction or adverse events presenting or reported by the patients post-injection were recorded.Results:At 1 month, 6 months and 12 months after the injection, about 203 (94.0%), 208 (96.3%) and 205 (94.9%) of the aesthetic seeking patients rated their full-face appearance as " excellently improved" or " much improved" on the GAIS, respectively. And 12 months after the injection, the overall facial satisfaction scores and appearance recognition scores of all aesthetic seeking patients were all significantly higher than those before injection ( P<0.01). 197 (91.2%), 198 (91.7%) and 198 (91.7%) of the aesthetic seeking patients were " very satisfied" or " relatively satisfied" with the treatment at 1 month, 6 months and 12 months, respectively. Treatment site responses most frequently reported were tenderness, bruising, topical swelling and skin redness. Most of the symptoms were moderate or mild feeling, lasting for no more than two weeks. Conclusions:The application of hyaluronic acid filler VYC-20L is safe and effective for full-face lifting in aesthetic seeking patients, which can significantly improve facial sagging and rejuvenate the face. The effect of improvements can last for 12 months.
