Objective:To systematically evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) in dysphagia after stroke.Methods:Six Chinese or English databases, including PubMed, Web of Science, Embase, CNKI, Wanfang and VIP, were searched by computer for randomized controlled trials of dysphagia after stroke with rTMS or tDCS (experimental group) from database construction to May 2023; those received conventional treatment+sham stimulation or conventional treatment only were enrolled as control group. Effective data were screened and extracted after literature quality evaluation by Cochrane. The outcome indexes included scores of penetration-aspiration scale (PAS), fiberoptic endoscopic dysphagia severity scale (FEDSS) and functional oral intake scale (FOIS). Reviewer Manager 5.4 software was used for Meta analysis of the extracted data, and mean difference ( MD) or standardized mean difference ( SMD) were used as effect indexes. Results:Twelve articles were finally included in the research literature, involving 637 subjects. Meta-analysis indicated that compared with the control group, the experimental group had significantly decreased PAS scores ( MD=-0.740, 95% CI: -1.020--0.460, P<0.001); FOIS scores in the experimental group were significantly increased compared with those in the control group ( MD=0.680, 95% CI: 0.220-1.130, P=0.003); FEDSS scores in the experimental group were significantly decreased compared with those in the control group ( SMD=-0.890, 95% CI: -1.110--0.670, P<0.001). Conclusion:The rTMS or tDCS can effectively alleviate dysphagia symptoms after stroke.

ObjectiveTo investigate the efficacy of Bushen Shengxue prescription and Yiqi Yangxue prescription in the treatment of chronic aplastic anemia and the effect on T cell subsets and the expression of T-box expressed in T cells （T-bet） and GATA binding protein 3 （GATA3）. MethodA total of 585 patients with chronic aplastic anemia who were treated in 19 hospitals in China from May 2018 to June 2021 were enrolled. With the prospective， double-blind and randomized control methods， the patients were randomized into three groups： kidney deficiency group， Qi and blood deficiency group， and control group. The three groups were respectively treated with Bushen Shengxue prescription granule， Yiqi Yangxue prescription granule， and Placebo （half the dose of Bushen Shengxue formula granules）. In addition， all of them were given oral cyclosporin and androgen. The treatment lasted 6 months， with 3 months as a course. The blood routine indexes， T cell subsets， and fusion genes T-bet and GATA3 before and after treatment were analyzed， and the safety indexes were monitored. ResultDuring the observation， a total of 75 cases dropped out and 18 were rejected. Finally， 161 cases in the kidney deficiency group， 164 in the Qi and blood deficiency group， and 167 in the control group were included. After 6 months of treatment， the total effective rate was 98.8% （159/161） in the kidney deficiency group， which was higher than the 79.9% （131/164） in the Qi and blood deficiency group （χ²=30.135， P<0.01） and the 61.7% （103/167） in the control group （χ²=70.126， P<0.01）. The total effective rate was higher in the Qi and blood deficiency group than in the control group （χ²=13.232， P<0.01）. After treatment， the hemoglobin （HGB） content increased significantly in three groups （P<0.05） as compared with that before treatment， particularly the kidney deficiency group （P<0.01）. After treatment， the white blood cell （WBC） count and platelet （PLT） count in the kidney deficiency group and the control group increased compared with those in the Qi and blood deficiency group （P<0.01）. There was no specific difference in neutrophils （ANC） after treatment among the three groups. At the same time point， the level of T helper type 1 （Th1） cells， Th1/Th2 ratio （P<0.05）， level of CD4⁺， and CD4⁺/CD8⁺ ratio （P<0.05） were significantly low in the kidney deficiency group among three groups. There was no significant difference in CD19^-， HLA/DR⁺， and CD25⁺ between the kidney deficiency group and the other two groups， but the T-bet of the kidney deficiency group and the control group was lower than that of the Qi and blood deficiency group （P<0.05）. ConclusionBushen Shengxue prescription exerts therapeutic effect on the aplastic anemia by improving the immunoregulatory mechanism， inhibiting the activity of immune system， modulating T cell subsets， suppressing Th1 and CD4⁺， and promoting bone marrow hematopoiesis. Moreover， it is safe with little side effects， which is worthy of further promotion.

Objective:To provide insight into the clinical characteristics, therapy and prognosis of patients with radiation-induced brainstem injury after radiotherapy.Methods:From August 2013 to September 2021, 13 patients with radiation-induced brainstem injury were included in this study at Sun Yat-sen Memorial Hospital, and the general information and strategy of radiotherapy were collected. A retrospective analysis was adopted to investigate the clinical and radiological characteristics, treatment and clinical outcomes.Results:There were 13 cases in total, including 4 females and 9 males. The onset age of enrolled patients ranged from 29 to 66 years with an average of (48.15±10.23) years. The median dose targeted at tumor area was 70 Gy with in 33 fractions. The median interval between radiotherapy and the diagnosis of radiation-induced brainstem injury was 24 months. The common clinical manifestations included dysphagia, bucking dysarthria, dizziness and problem with balance. The MRI radiological features were hypointense on T1WI, hyperintense on T2WI, and irregularly enhanced with contrast. The median follow-up was 45 months. Seven cases got improvements, while 3 had no obvious efficacy and 3 cases died. No significant differences in prognosis were observed between those received traditional glucocorticoid and those received bevacizumab treatment( P=0.079). Conclusions:The common symptoms of radiation-induced brainstem injury were symptoms of posterior cranial nerves injury and ataxia. Lesions mostly happened in pons and medulla, with hypointense on T1WI and hyperintense on T2WI. Half of the patients have improved after treatment. There was no significant difference in prognosis between glucocorticoid and bevacizumab treatment.

Objective:To explore the application of 16-words formula " resection surrounding the proximal part of seminal colliculus, lateral tunnel, plane extending and bladder neck preservation" in transurethral enucleation resection of prostate with plasma rod electrode (TUERP).Methods:The clinical data of 88 patients with benign prostatic hyperplasia (BPH) admitted to our department from May 2018 to July 2019 were retrospectively analyzed. The age of patients was (67.0±8.6)years, and the volume of prostate was (51.0±27.3)ml. All patients were treated with TUERP using transurethral plasma rod electrodes according to the above 16-words formula. The perioperative clinical data and follow-up results at the 3rd month postoperation were statistically analyzed.Results:All operations were successfully completed. The operation time was (49.7±17.7)min, including gland enucleation time (16.8±6.7)min, tissue resection time (33.0±12.3)min, enucleated tissue weight (45.5±24.4)g, intraoperative blood loss (10.2±2.9)ml, postoperative continuous bladder irrigation time (1.9±0.8)d, postoperative hospital stay (4.1±0.7)d. There were no significant changes in hemoglobin and sodium concentration at 2 hours after operation ( P>0.05). The International Prostate Symptom Score (IPSS), quality of life score (QOL), maximum urinary flow rate (MFR) and residual bladder urine were significantly improved at 3 months after operation ( P<0.05). The patients were followed up for 3 to 14 months (average 6.8 months). There were 6 cases of Clavien grade Ⅰ complications, 1 case of Clavien Ⅱ complications, 1 case of Clavien Ⅲ complications, and no Clavien Ⅳ-Ⅴ complications occurred. Conclusions:The TUERP with plasma rod electrode according to the 16-words formula is an ideal choice for BPH treatment, which has the advantages of simple operating, high efficiency of enucleation, less blood loss, fast recovery and satisfied improvement of urination symptom.

Objective:To explore the current status of clinical teaching staff for the graduate program of master of nursing specialist (abbreviated to nursing masters) in traditional Chinese medicine (TCM) universities and compare it with the role expectations of students, aiming to provide a reference for the subsequent construction and improvement of clinical teaching staff.Methods:Totally 172 nursing masters from Jiangsu, Zhejiang, Henan provinces and Tianjin and 86 clinical teaching staff from the hospitals where they practiced were selected using convenient samping and investigated with the self-made questionnaire from October to December 2018. The differences between clinical teaching staff's resources, abilities and students' expectations were compared. A total of 258 questionnaires were distributed among 86 clinical teachers and 172 nursing masters, and 258 valid questionnaires were recovered, with an effective rate of 100%. SPSS 22.0 software was used for statistical analysis of data.Results:There was a certain gap between the clinical teaching staff and students' expectations, especially in terms of the graduate school and academic qualifications of the clinical teachers. Totally 34.88% (30/86) of the clinical teachers graduated from TCM universities, while 71.51% (123/172) of the students expected to be taught by teachers graduating from TCM universities. Among the clinical teachers, 60.47% (52/86) were undergraduates, and fewer were masters or graduates with higher education. There was a certain difference between the teaching teachers' abilities and students' expectations. There were statistically significant differences in 17 secondary indicators (χ 2 were 12.027-130.149, P<0.05) , except for the professional attitude in clinical nursing abilities, decision-making abilities in clinical management abilities, communication abilities in interpersonal abilities, and collaboration abilities ( P>0.05) . There were statistically significant differences between students' current status and their learning needs for TCM nursing (χ 2 were 14.722-165.339, P<0.01) . TCM nursing skills and practical application of TCM nursing research were the contents that most students wanted to learn, accounting for 83.72% (144/172) and 70.35% (151/172) , respectively. Conclusions:There were differences between the current status of the teaching staff for nursing masters at TCM universities and the expectations of the students. The universities should fully consider the graduates' own expectations and needs based on the training objectives for graduates, actively explore the admission system for clinical teachers, improve the training system for teachers, and standardize the teaching evaluation mechanism based on the status quo of nursing talents in China.

Objective To investigate the characteristics,treatment and prognosis of radiation-induced sympathetic chain injury.Methods We observed 6 cases with radiation-induced sympathetic chain injury and re-viewed the clinical features,treatment and prognosis of these patients. Results The median age of these 6 cases was 50 and the interval between radiotherapy to onset was 7.7 years.Dizziness was the first and most common symp-tom and dramatic fluctuation of blood pressure was the most common physical sign.Steroids might be considered for the treatment of radiation-induced sympathetic nerve injury. However,the therapeutic effect still needs to be proved.Conclusions Sympathetic nerve injury is an uncommon but dramatic symptom in NPC patients after radio-therapy.

In order to clarify dynamic change of microbial community composition and to identify key functional bacteria in the cellulose degradation consortium, we studied several aspects of the biodegradation of filter papers and rice straws by the microbial consortium, the change of substrate degradation, microbial biomass and pH of fermentation broth. We extracted total DNA of the microbial consortium in different degradation stages for high-throughput sequencing of amplicons of bacterial 16 S rRNA genes. Based on the decomposition characteristics test, we defined the 12th, 72nd and 168th hours after inoculation as the initial stage, peak stage and end stage of degradation, respectively. The microbial consortium was mainly composed of 1 phylum, 2 classes, 2 orders, 7 families and 11 genera. With cellulose degradation, bacteria in the consortium showed different growth trends. The relative abundance of Brevibacillus and Caloramator decreased gradually. The relative abundance of Clostridium, Bacillus, Geobacillus and Cohnella increased gradually. The relative abundance of Ureibacillus, Tissierella, Epulopiscium was the highest in peak stage. The relative abundance of Paenibacillus and Ruminococcus did not change obviously in each stage. Above-mentioned 11 main genera all belonged to Firmicutes, which are thermophilic, broad pH adaptable and cellulose or hemicellulose degradable. During cellulose degradation by the microbial consortium, aerobic bacteria were dominant functional bacteria in the initial stage. However, the relative abundance of anaerobic bacteria increased gradually in middle and end stage, and replaced aerobic bacteria to become main bacteria to degrade cellulose.

Objective To investigate the role of interleukin-22 (IL-22)-regulated autophagy in hydrogen peroxide (H2 O2 )-induced hepatocarcinoma cell damage. Methods HepG2 cells were transfected with pEGFP-LC3 and then cultured in RPMI 1640 medium free of fetal bovine serum (FBS) or containing 1％ or 10％ FBS. These cells were pretreated with rapamycin or an autophagy inhibitor (3-MA) and then stimulated with recombinat human IL-22 (rhIL-22). GFP-LC3 puncta formation and autophagy signaling ac-tivation were measured. MTT assay was performed to detect cell viability. Results rhIL-22 significantly promoted GFP-LC3 puncta formation and LC3-Ⅱ expression in HepG2 cells treated with different stimulation protocols. The autophagy pathway inhibitor, 3-MA, dramatically suppressed the rhIL-22-activated autophagy signals. rhIL-22 attenuated H2 O2-mediated HepG2 cell death and that could be inhibited by 3-MA. Conclu-sion IL-22 promoted the activation of autophagy signaling pathways and alleviated H2 O2-mediated HepG2 cell damage.

Objective To evaluate the efficacy and safety of donepezil in the treatment of cognitive dysfunction caused by radiation-induced encephalopathy.Methods A total of fifty-five patients with radiation-induced cognitive impairment were divided into treatment group with extra donepezil 5-10 mg/d combined with conventional therapy and control group with conventional treatment for 16 weeks.The cognitive function was assessed according to Montreal cognitive assessment (MoCA) and mini-mental state examination (MMSE) before and 16 weeks after treatment.Results After 16 weeks of treatment,the patients in treatment group displayed significantly greater improvement in cognitive function.In treatment group,the scores of patients after donepezil therapy in MoCA and MMSE were obviously higher than the control group (t =5.40,3.88,P ＜ 0.01).The scores in the visual space and executive function,naming,attention,abstract thinking,delayed memories also had improved,which suggested the statistically significant difference(t=-3.55,-3.08,-3.21,-2.58,-3.65,P＜0.05).The scores of control group unchanged accordingly.Conclusions Donepezil combined with conventional treatment was signally effective in the therapy of cognitive dysfunction caused by radiation-induced encephalopathy.
