Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

OBJECTIVE:
To investigate the toxicity management and efficacy evaluation of BCMA-chimeric antigen receptor T cells(CART) in the treatment of relapsed and refractory multiple myeloma (MM).
METHODS:
The efficacy and adverse reactions of 21 patients with MM who received BCMA-CART treatment at the First Affiliated Hospital of Wenzhou Medical University from December 2017 to September 2020 were evaluated, and the efficacy assessment and survival analysis for high-risk patients and non-high-risk patients were evaluated.
RESULTS:
After infusion of BCMA-CART cells in 21 MM patients, the number of effective cases was 17, of which the complete remission (sCR/CR) was 10, and the partial remission (VGPR/PR) was 7. The median OS time for all patients was 19.4 months, and the median PFS time was 7.9 months. The number of patients with extramedullary disease(EMD), high-risk genetics, and ISS stage Ⅲ were 5, 15 and 8, and the effective number was 3, 11 and 6, respectively. The treatment of 3 patients without high-risk factors was effective. The median OS and median PFS of patients with EMD were 14.2 and 2.5 months, respectively, which were shorter than those of patients without EMD (19.4 months and 8.9 months, respectively). The median OS and median PFS of patients with high-risk cytogenetic factors and ISS Ⅲ were not significantly different from those of non-high-risk patients. Cytokine release syndrane (CRS) occurred in 20 patients, of which 14 cases were Grade 1 CRS, while 6 were Grade 2, no CRS of Grade 3 or above occurred. IL-6 receptor inhibitors were used in 9 patients. All CRS were controlled effectively, and no patients had neurological toxicity.
CONCLUSION
BCMA-CART is a certain curative effect in the treatment of relapsed and refractory multiple myeloma, and the adverse reactions can be well controlled through close monitoring and timely treatment.

Mistakenly picking and eating poisonous mushrooms can cause acute poisoning. In August 2020, Qingdao Hospital of Traditional Chinese Medicine handled a poisonous mushroom poisoning incident, conducted epidemiological investigation on all poisoned patients, collected suspicious food, clinical manifestations, clinical test results and treatment conditions, and identified the mushrooms as Amanita fuliginea poisoning after morphological identification. In this incident, 6 people ate grey goose paste, of which 4 were sick with a incubation period of 6~12 h. The clinical manifestations were gastrointestinal symptoms such as nausea, vomiting and diarrhea, liver and kidney damage. After symptomatic support treatment, hemoperfusion or continuous hemofiltration treatment, the patients were cured and discharged. It is suggested to strengthen the popular science education on poisonous mushroom poisoning and improve the ability of identification and clinical treatment of poisonous mushrooms in grass-roots medical institutions.

ObjectiveTo investigate the clinical effects of circumcision by surgical plane positioning with a disposable circumcision suture device in the treatment of phimosis and redundant prepuce.
METHODSFrom September 2016 to June 2017, we treated 250 patients with phimosis or redundant prepuce, 127 by conventional circumcision (the control group) and the other 123 by surgical plane positioning with a disposable circumcision suture device (the observation group). We compared the operation time, intra-operative bleeding, preputial frenulum alignment, postoperative ecchymosis, and postoperative penile appearance between the two groups of patients.
RESULTSCompared with the controls, the patients in the observation group showed significantly longer operation time ([4.48 ± 1.18] vs [7.17 ± 1.42] min, P<0.05), lower rates of intra-operative frenulum bleeding (15.0% [19/127] vs 4.1% [5/123], P<0.05) and frenulum misalignment (26.8% [34/127] vs 0.8% [1/123], P<0.05), higher incidence of postoperative ecchymosis (41.7% [53/127] vs 21.1% [26/123], P<0.05), and higher satisfaction of the patients with the postoperative penile appearance (92.9% [18/127] vs 98.4% [121/123], P<0.05). However, no statistically significant difference was found between the control and observation groups in intra-operative non-frenulum bleeding (4.7% [6/127] vs 1.6% [2/123], P = 0.164).
CONCLUSIONSCircumcision by surgical plane positioning with a disposable circumcision suture device can effectively avoid preputial frenulum misalignment, reduce intra-operative bleeding, and improve postoperative penile appearance.

This study examined the prevalence of primary open-angle glaucoma (POAG) among residents aged ≥50 years living in Yongchuan district of Chongqing. Stratified cluster sampling was employed in random selection to estimate the prevalence of glaucoma from April to June, 2005. Twenty-nine villages or neighborhood communities were randomly selected in urban area (Zhongshan Road), suburban area (Shanjiao Town) and exurban area (Zhutuo Town) of this district. All the respondents underwent detailed ophthalmic examinations. The examinations included questionnaire investigation, visual acuity test, naked-eye examination, measurement of peripheral anterior chamber depth (Van Herrick's technique), detection of intraocluar pressure (IOP) with a Perkins hand-held applanation tonometer (HA-2) and examination of the optic disc by using a 78 diopters (D) lens (including the cup-disc ratio, cup/disc ratio asymmetries, horizontal and vertical diameter, notching and optic disc hemorrhages). A total of 5938 residents were actually examined, and the response rate was 85.19%. The crude prevalence of POAG was 0.86% (n=51/5938, 95% CI 0.64%-1.11%). There were 24 males and 27 females in the glaucoma group. The glaucoma prevalence was not significant different in case number between the male and female subjects (P=0.4900). Furthermore, no association between age or schooling and POAG was noted (P=0.8030, 0.0734). Out of 51 subjects with POAG, unilateral glaucoma-related blindness occurred in 38 subjects (74.5%) and bilateral glaucoma-related blindness was found in 7 subjects (13.7%). This study exhibited that the prevalence of POAG was 0.86% among residents aged ≥50 years living in Yongchuan District of Chongqing. The vision loss caused by POAG in this population was obviously higher than that previously reported in other studies. Glaucoma management, detection of affected persons and handling of the burden of glaucoma should be the priorities of the agenda of local health authorities of Western China.

ObjectiveTo investigate the distribution and expression of y-secretase subunit (APH-1)in the central nervous system (CNS) of APP/PS1 double transgenic Alzheimer's disease (AD) adult mouse model,and to detect the expression difference of APH-1 in developmental brain between AD model mouse and wild-type littermates in order to further clarify the relationship between APH-1 and AD. MethodsOffspring bred by APP/PS1 double transgenic AD mice were genotyped.Immunohistochemical staining was used to detect APH-1 distribution and expression in the CNS of adult APP/PS1 double transgenic AD mouse model,in the brain of AD model mouse and its wild-type littermates on postnatal day 1,7,21 and 120.Results APH-1 was widely expressed in almost all regions of the CNS,especially in the cerebral cortex,hippocampus,olfactory bulb,hypothalamus,ventral striatum,caudate putamen,raphe magnus nucleus,cerebellum,brainstem and spinal cord of the adult APP/PS1 double transgenic mice.APH-1 expression was higher in the cortex of both AD and wild type mouse on postnatal day 1 than on postnatal day 7 and 21 with increased level of APH-1 protein in adult mouse brain.APH-1 expression in the brain of AD mice was higher than in its wild type littermates at any stage(P<0.05).Conclusions Distribution of APH-1 is ubiquitous and region-dependent in the CNS.The different distribution and expression between APP/PS1 double transgenic mouse model and its wild type littermate indicate that APH-1 may be related to AD.
