Background & Objective: Sleep quality in neuromyelitis optica spectrum disorders (NMOSD) were investigated in two recent studies. However, factors affecting sleep quality have not been studied in NMOSD. This study aimed to investigate the prevalence of sleep disorders in Chinese outpatient clinics with NMOSD and its clinical correlates. Methods: We administered Chinese validated self-questionnaires on HRQOL (MSQOL-54), sleep (PSQI), pain (SF-MPQ-2), anxiety (HARS) and depression (HDRS) to 42 patients followed up in our outpatient department. We assessed the relationships between sleep quality with pain, anxiety, depression, gender, age, disability, disease duration, NMO-antibody status and explored the determinants of poor sleep quality. Results: Sixty four percent of NMOSD patients were poor sleepers. Significant correlations were found between duration, disability, pain, anxiety, depression and sleep quality. Disability, depression and the domain of affective descriptors of pain were the three main predictors of poor sleep in NMOSD. Conclusion: This study reveals that poor sleep in NMOSD is common and it decreases physical function of quality of life. It is worthwhile considering exploring adjuvant strategies aimed at controlling pain associated affect, and treatment of depression may help to improve sleep quality in NMOSD.

To study the effect of the Tangshenping containing serum on the proliferation of the high glucose-induced epithelial cells of renal tubules.To prepare durg-contained serum from rats to enter into in vitor reaction system,the cellscultured via 10％ FBS-RPMI 1640 were randomly divided into 7groups:the normal group,themodel group,the Y27632 group,theirbesartangroup,the small dose Tangshenping group,the medium dose Tangshenping group and the high dose Tangshenping group and The cells were cultured in 3000 cells/well and grown in 96-well plates.Each group had 8 wells,then detect the effects of all serum sections on the proliferation of high glucose-induced epithelial cells of kidney tubules by the MTT colorimetric method after cultured for 12 h,24 h,48 h,and 60 h.Based on the results above,cell protein were extracted from each group at 24 h,and the expression of RhoA,ROCK1,α-SMA and E-cadherin in each group were detected by Western blotting.After high glucose stimulation,the shape of cell was shuttle-like or irregular triangle,the way it grew was radial;after the intervention of the corresponding serum,the shape of the cell was fiat and irregular polygonal.Started with 12h,compared with the normal group,OD value of other groups increased;at the 24h、48hand 60h,compared with the normal group,OD value of high glucose groupincreased significantly (P＜0.01);compared with the high glucose group,OD value of treatment groups decreased (P＜0.05);and 48 h,compared with the Y27632group,irbesartan groupand Tangshenping high dose group,OD value of Tangshenping low and medium dose groups decreased (P＜0.05);60 h,compared with Y27632 group,OD value of Tangshenping medium dose groups decreased;compared with irbesartan group,OD value of o Tangshenpinggroupsdecreased (P＜0.05);compared with Tangshenping high dose group,OD value of Tangshenpinglow groupsdecreased (P＜0.05) Western blotting analysis showed that compared with normal group,the expression of E-Cadherin protein in high glucose group reduced,and the expression of RhoA,ROCK1 and α-SMA protein increased;compared with high glucose group,the expression of E-Cadherin protein in each treating group increased,and the Tangshenping large dose group wassignificantly different (P＜0.01);the expression of RhoA,ROCK1 and or-SMA protein reduced,Tangshenping,the large dose group was significantlydifferent (P＜0.01);Compared with the Y27632 group,the expression of E-cadherin,ROCK1 and α-SMA protein in Tangshenping large dose group had no significant difference,while the expression of RhoAproteinreduced (P ＜0.01).Compared with theirbesartan group,the expression of E-cadherin,RhoA,ROCK1 and α-SMA protein in Tangshenping large dose group had no significant difference (P＞0.05).The Tangshenping containing serum is abletoinhibit the proliferation of high glucose-induced epithelial cells of kidney tubules,and can reverse renal tubular-epithelial cell transdifferentiation via regulating RhoA/ROCK signaling pathway,and restrain renal interstitial fibrosis,thereby delaying the pathogenesis of diabetic kidney disease.

Objective To assess the quality of reports of clinical randomized controlled trials (RCTs) published in Chinese Journal of Dermatology from 2007 to 2016,and to provide a reference for standardization of clinical paper writing.Methods Based on the consolidated standards of reporting trials (CONSORT) 2010 statement,an evaluation form was designed and used to assess the quality of the clinical RCT articles published in Chinese Journal of Dermatology from 2007 to 2016.Results A total of 94 RCT articles were enrolled,including 45 articles from 2007 to 2011,and 49 articles from 2012 to 2016.Among these articles,the writing of introduction and discussion parts was relatively standardized.In the method and result parts,the proportions of articles correctly reporting blinding (23 articles,24.47％),sample size (0 article),primary and secondary outcome measures (21 articles,22.34％),participant flow (0 article),loss to follow-up (32 articles,34.04％) and compliance (13 articles,13.83％) were low,while the proportions of those correctly reporting inclusion and exclusion criteria,intervention measures,statistical methods,starting and ending time of follow-up and baseline data were all over 80％.Conclusion Most contents of the RCT articles published in Chinese Journal of Dermatology are standardized and clear,but the reporting of blinding,compliance,sample size,participant flow and so on,is insufficient,and close attention should be paid to these items.

Objective To investigate the clinical characteristics and the experience of multi-disciplinary team (MDT) on recurrence of primary hyperoxaluria (PH) type I after renal transplantation. Methods One case presenting with unexplained rapid decline of renal allograft function after allogeneic renal transplantation was discussed by MDT. The role of MDT in diagnosing rare hereditary diseases and improving the long-term survival of renal transplant recipients was summarized. Results After MDT consultation, the patient was diagnosed with recurrence of PH type I. Routine immunosuppressive regimen was initiated after the exclusion of rejection. The patient was instructed to drink a large quantity of water, and given with high-quality protein and low-phosphorus diet, vitamin B6, calcium and other conservative therapies to actively prevent and treat postoperative complications. The deterioration of renal graft function was delayed. Nevertheless, regular hemodialysis was resumed at 5 months after renal transplantation until the submission date of this manuscript. Conclusions Recurrence of PH type I after renal transplantation is relatively rare. The main clinical manifestations are recurrent kidney stones and decreased renal function with multiple complications and poor prognosis. The condition of the patient is consulted by MDT for confirming the diagnosis, determining the optimal treatment scheme, delaying the progression and improving the clinical prognosis.

Objective To investigate the effect of combined auricular needling and nerve growth factor (NGF) treatment on leaming and memory abilities of Alzheimer' s disease (AD) model rats,as well as their possible mechanisms.Methods Forty male SD rats were randomly assigned into four groups:normal control group,AD model group,auricular needling group,and combined auricular needling and NGF treatment group.Okadaic acid was injected into the hippocampal CA 1 region of rats to establish AD models,simultaneously,5 μL NGF (0.1 g/L) was injected into the lateral ventricle of cerebrum for 5 times every other day while acupuncture at "ear-kidney-brain" auricular points was implemented as well.Morris Water Maze behavioral test was performed to assess the learning and memory abilities of the rats.The neuron apoptosis of the hippocampus was detected by flow cytometer.The expressions ofglial fibrillary acidic protein (GFAP) and choline acetyl-transferase (CHAT) were examined by immunohistochemistry.The neurofibrillary tangle (NFT) was observed through Bielschowsky staining of the hippocampus,and Western blotting was used to observe the Tau protein hyperphosphorylation at Ser396 locus.Results As compared with auricular needling group,the combined auricular needling and NGF treatment group had significantly shortened average escape latency in place navigation test,prolonged active time in the third quadrant in spatial probe test,increased number of platform-crossing,decreased apoptosis ratio,decreased GFAP expression and NFT in the hippocampal CA1 region,increased ChAT expression in hippocampal CA1 region,and decreased phosphorylated Tau expression at the site of Ser396 (P＜0.05).Conclusion (1) Acupuncture at "Ear-Kidney-Brain" auricular points combined with NGF obviously improves the learning and memory abilities of the model rats;and it is more effective than auricular needling alone.(2) The mechanisms might be related with reduced neurons apoptosis,decreased abnormal activation and hyperplasia of astrocyte,improved central cholinergic system functions,and inhibited hyperphosphorylated Tau expressions.

Objective:To summarize the clinical characteristics of central nerve system (CNS) infection and grasp the necessity and possibility of early diagnosis and precise intervention of CNS infection after renal transplantation.Methods:This retrospective study enrolled consecutive recipients of renal transplantation with CNS infection after transplant between January 2000 and December 2020. Correlative factors for CNS infection after renal transplant were determined by comparing the clinical data between recipients with and without CNS infection. After screening 3, 199 consecutive renal transplant recipients, 12 patients with CNS infection post-transplant were identified and recruited. The median age-of-onset was 48.5 (23-65) years. And the median time to disease onset after transplant was 50.5(1-204) months. The most common symptoms of CNS infection after renal transplant included fever (75.00%), consciousness disorder (58.33%), headache (58.33%) and neck rigidity (41.67%).Results:Hepatitis B virus carrier and pulmonary infection were correlated with CNS infection after transplantation ( P<0.05). Nine patients failed to identify the pathogen and only received empirical anti-infective regimen. The outcomes were curing ( n=3) and death ( n=6). Metagenomic sequencing was performed for identifying the pathogen in three recipients and actively adjusting the anti-infective regimen. As a result, 2 were cured and 1 died. The overall mortality was 58.33%. The median time to death or curing from disease onset were 20(2-19) and 25(16-35) days respectively in surviving and non-surviving recipients. Conclusions:The progress of CNS infection after transplantation is rapid with a high mortality. HBV carrier and pulmonary infection are possible risk factors of CNS infection after renal transplantation. Early pathogenic identification and precise etiological intervention are vital for better clinical outcomes.

Objective:To observe the effects of warm acupuncture on post-stroke cognitive impairment (PSCI) based on the theory of intestinal flora.Methods:A randomized controlled trial was conducted. 60 patients with PSCI in the Department of Acupuncture and Neurology of the First Affiliated Hospital of Xinjiang Medical University from October 2020 to June 2022 were selected as the observation objects, and were divided into 2 groups by random number table, with 30 cases in each group. On the basis of cognitive rehabilitation training, the treatment group was given warm acupuncture treatment, and the control group was given routine acupuncture treatment. 2 groups were treated for 4 weeks as 1 course, and a total of 4 courses were treated. Montreal cognitive assessment (MoCA) was used to assess patients' cognitive function before and after treatment, and mini-mental state examination (MMSE) was used to assess patients' intelligence level. The numbers of bifidobacteria and lactic acid bacteria in fecal samples were calculated, and plasma gamma-aminobutyric acid (GABA) levels were detected by ELISA to evaluate the clinical efficacy.Results:During the study, 1 case was lost in each of the two groups, and finally 29 cases were included in the curative effect statistics. The total effective rate was 79.3% (23/29) in the treatment group and 65.5% (19/29) in the control group, with statistical significance ( χ2=43.39， P<0.05). After treatment, MoCA score [(24.23±1.36) vs. (21.26±1.30), t=3.12] and MMSE score [(25.35±1.24) vs. (21.52±1.22), t=3.25] in the treatment group were higher than those in the control group ( P<0.05); Bifidobacterium [(9.20±1.25) LgCFU/g vs. (7.23±1.21) LgCFU/g, t=2.98], Lactic acid bacteria [(8.24±1.12) LgCFU/g vs. (6.25±1.22) LgCFU/g, t=2.92], and the level of GABA [(283.80±83.54) mmol/L vs. (264.76±61.38) mmol/L, t=10.54] were higher than those in the control group ( P<0.05 or P<0.01). Conclusion:Warm acupuncture and moxibustion can effectively regulate the number of intestinal beneficial bacteria in PSCI patients, increase the level of GABA, promote brain tissue repair and improve cognitive function.

DNA is a biological polymer that encodes and stores genetic information in all living organism. Particularly, the precise nucleobase pairing inside DNA is exploited for the self-assembling of nanostructures with defined size, shape and functionality. These DNA nanostructures are known as framework nucleic acids (FNAs) for their skeleton-like features. Recently, FNAs have been explored in various fields ranging from physics, chemistry to biology. In this review, we mainly focus on the recent progress of FNAs in a pharmaceutical perspective. We summarize the advantages and applications of FNAs for drug discovery, drug delivery and drug analysis. We further discuss the drawbacks of FNAs and provide an outlook on the pharmaceutical research direction of FNAs in the future.

Objective To investigate the feasibility and clinical experience of kidney transplantation from donors with Marfan syndrome (MFS). Methods Clinical data of 2 recipients undergoing kidney transplantation from the same MFS patient were retrospectively analyzed and literature review of 2 cases was conducted. Characteristics and clinical diagnosis and treatment of kidney transplantation from MFS patients were summarized. Results The Remuzzi scores of the left and right donor kidneys of the MFS patient during time-zero biopsy were 1 and 2. No significant difference was observed in the renal arteriole wall compared with other donors of brain death and cardiac death. Two recipients who received kidney transplantation from the MFS patient suffered from postoperative delayed graft function. After short-term hemodialysis, the graft function of the recipients received the left and right kidney began to gradually recover at postoperative 10 d and 20 d. After discharge, serum creatinine level of the recipient received the left kidney was ranged from 80 to 90 μmol/L, whereas that of the recipient received the right kidney kept declining, and the lowest serum creatinine level was 232 μmol/L before the submission date (at postoperative 43 d). Through literature review, two cases successfully undergoing kidney transplantation from the same MFS donor were reported. Both two recipients experienced delayed graft function, and then renal function was restored to normal. Until the publication date, 1 recipient has survived for 6 years, and the other recipient died of de novo cerebrovascular disease at postoperative 2 years. Conclusions MFS patients may serve as an acceptable source of kidney donors. However, the willingness and general conditions of the recipients should be carefully evaluated before kidney transplantation. Intraoperatively, potential risk of tear of renal arterial media should be properly treated. Extensive attention should be paid to the incidence of postoperative complications.
