Objective To compare postoperative adjuvant chemoradiotherapy with adjuvant chemotherapy in patients with gastric cancer by a meta-analysis.Methods PubMed,EMbase,Cochrane Library,Wanfang,CNKI,VIP,and CBM databases were searched to identify the controlled clinical trials of postoperative adjuvant chemoradiotherapy versus adjuvant chemotherapy for gastric cancer.The obtained data were analyzed using RevMan 5.2.5 and Stata 12.0.The difference between two groups was estimated by calculating the odds ratio (OR) with 95％ confidence interval (CI).Results A total of 12 controlled clinical trials involving 1674 gastric cancer patients,which were selected according to inclusion and exclusion criteria,were included in this meta-analysis.The meta-analysis showed that the 3-and 5-year survival rates were significantly higher in the adjuvant chemoradiotherapy group than in the adjuvant chemotherapy group (OR=2.96,95％ CI=1.75-5.03,P=0.000; OR=1.45,95％ CI=1.06-1.99,P =0.020);the local recurrence rate was significantly lower in the adjuvant chemoradiotherapy group than in the adjuvant chemotherapy group (OR =0.50,95％ CI =0.34-0.72,P =0.000) ; there was no significant difference in distant metastasis rate between the two groups (OR =0.79,95％ CI =0.58 -1.07,P =0.130).Conclusions The meta-analysis of existing study results shows that compared with adjuvant chemotherapy alone,adjuvant chemoradiotherapy is a relatively safe and effective postoperative treatment for gastric cancer.

Objective:To understand the incidence, severity and the change trajectory of symptoms in adult patients with acute leukemia during treatment, so as to provide a reference for clinical medical staff to conduct specific symptom screening and management.Methods:From March 2017 to August 2018, 69 patients who were newly diagnosed with acute leukemia at the Nanfang Hospital of Southern Medical University were conveniently selected. The Memory Symptom Assessment Scale was used to investigate the patients before chemotherapy (T1), after the first chemotherapy (T2), after the second to third chemotherapy (T3) and after the fourth to fifth chemotherapy (T4).Results:The severity score of psychological symptoms in adult patients with acute leukemia at T1, T2, T3, and T4 were 1.00(0.58, 1.42), 1.00(0.83, 1.67), 0.67(0.33, 1.00) and 0.67(0.33, 1.00). The severity score of physical symptoms at T1, T2, T3, and T4 were 0.50(0.21, 0.83), 1.00(0.54, 1.33), 0.75(0.58, 1.17) and 0.92(0.63, 1.08), respectively. The score difference was statistically significant ( H = 28.34, 27.14, both P<0.01) at different time points. The score of physical symptoms reached a peak at T2. In the psychological dimension, the severity and incidence of energy deficiency were higher in T1-T4. Conclusions:Adult acute leukemia patients have different focal symptoms in different treatment stages. Clinical medical staff should provide effective and personalized nursing intervention for patients in different treatment stages.

Objective To explore the effect of a mind map combined with memorial system by making up stories in knowledge training on first aid medicine. Methods A total of 91 nurses worked at Wenzhou People′s Hospital were selected as study subjects by purposive sampling from February to July 2016. The mind map combined with memorial system by making up stories was applied to knowledge training on first aid medicine. This research carried out speculative knowledge and skill exams for nurses before and after implementation. Results The scores of speculative knowledge and skill of nurses after implementation were (80.74±5.27) and (78.46±5.10) higher than those [(61.58±7.44),(59.13±8.53)] before implementation with significant differences (t=27.56,37.81;P<0.001). Conclusions The mind map combined with memorial system by making up stories can effectively improve the mastery of knowledge on first aid medicine. It is worthy of being applied.

Objective To understand the status quo of self-concept clarity and professional life quality of male nurses, and to analyze the influence of self-concept clarity on professional life quality of male nurses. Methods In August 2017, a total of 251 male nurses from six Class Ⅲ hospitals in Zhejiang Province were selected by convenience sampling method. Self-Concept Clarity Scale and the Chinese version of Professional Quality of Life Scale Version 5 were applied in the investigation. A total of 251 questionnaires were distributed and 235 valid questionnaires were collected, with an effective recovery rate of 93.63％.Results The score of Self-Concept Clarity Scale and the Chinese version of Professional Quality of Life Scale Version 5 was (31.47±6.95) and (91.82±16.95) respectively in the 235 male nurses. There was a positive correlation between the two (r=0.324,P<0.05). Hierarchical regression analysis showed that working years, monthly income and self-concept clarity were the influencing factors of professional life quality of male nurses.Conclusions The level of self-concept clarity and professional quality of life among male nurses is at a moderate level. Self concept clarity is an important factor affecting the quality of professional life. It is necessary to strengthen the guidance of public opinion and increase the media publicity of male nurses so as to promote the acceptance and acceptance of male nurses and increase their job stability through social and family perspectives.

Antipsychotics, lithium preparations can cause a variety of renal side effects, most of which occur insidiously. The paper reports a 46-year-old female patient developing fatigue and soft paresis after taking lithium carbonate for 17 years. Laboratory tests showed hypokalemia, distal renal tubular acidosis (dRTA), and renal calculus. After discontinuation of lithium carbonate, partial remission of hypokalemia and dRTA were observed. Combined with literature review, in addition to dRTA, the renal side effects of lithium preparations also include acute toxic kidney injury, nephrogenic diabetes insipidus and various glomerulopathy.

Objective:To compare the efficacy and safety of red light and daylight photodynamic therapy in the treatment of facial common acne.Methods:From March 2019 to November 2019, 52 patients with facial common acne who received 5-aminolevulinic acid photodynamic therapy in the Department of Dermatology, Chongqing Hospital of Traditional Chinese Medicine were enrolled, including 34 males and 18 females, aged 18-35 years, with an average age of 23.2 years. A 5% concentration of 5-aminolevulinic acid was applied to the entire face, with the right side of the face being exposed to red light for 20 minutes and the left side to daylight for 2 hours. The treatment was administered once a week for a total of 4 sessions. After the treatment, the acne remission, adverse reactions, and patient satisfaction on both sides of the face were compared.Results:Compared with before treatment, the number of inflammatory and non-inflammatory lesions on both sides of the face in the enrolled patients decreased, and there was no significant difference in the clearance rate of skin lesions between the two sides [53.7% (28/52) vs 59.1% (31/52), χ 2=0.89, P>0.05]. The overall effective rate on the red light side was 88.5% (46/52), and 82.7% (43/52) on the daylight side, with no significant difference between the two (χ 2=0.38, P>0.05). In terms of adverse reactions, mild erythema was common, and it was less on the daylight side than on the red light side [34.6% (18/52) vs 19.2% (10/52), χ 2=5.98, P<0.05]. During the treatment period, the pain score on the daylight side decreased compared to the red light side [(7.6±2.3) vs (4.1±1.3), t=13.10, P<0.001]. Overall satisfaction with the daylight side was reported in 49 cases (94.2%), and with the red light side in 37 cases (71.2%), with the daylight side being higher than the red light side, and the difference was statistically significant (χ 2=9.60, P<0.05). Conclusion:Daylight photodynamic therapy is as effective as red light photodynamic therapy for common acne, but it produces fewer adverse reactions and higher patient satisfaction.

Objective To analyze miR-92a expression and its clinical significance in the plasma of systemic lupus erythematosus (SLE) patients.Methods Plasma samples from 44 SLE patients,16 rheumatoid arthritis (RA) patients and 20 healthy controls were collected.The small RNAs in these plasma samples were isolated and reversely transcribed.Using cel-miR-39 as the external reference,the levels of miR-92a expression were detected by real-time polymerase chain reaction (PCR) method.MiR-92a and cel-miR-39 were analyzed by real-time fluorescence quantitative PCR and agarose gel electrophoresis.The sensitivity and specificity of miR-92a as SLE were analyzed by receiver-operating characteristic (ROC) curve.The correlation between the levels of miR-92a expression and the clinic pathological features of SLE and biological significance of miR-92a expression in SLE were further analyzed by Pearson or Chi-square test.Results Our data indicated that the plasma levels of miR-92a expression was 49.20 (5.33,95.17) in SLE patients,411.30 (320.84,504.69) in healthy controls,and 25.59(11.20,30.54) in RA patients.The difference was significant (x2=40.77,P＜0.01).The area under the ROC curve (AUC) was 0.958 for discriminating between SLE patients and normal subjects and 1.00 for discriminating between RA patients and healthy controls.The levels of miR92a expression cutoff values were set the as 198.59 for healthy control and 85.35 for RA patients,the diagnostic sensitivity and specificity were 93.2％,90％,and 100％,100％,res-pectively.The analysis of the correlation between miR-92a expression and the clinic pathological features of SLE had shown that the levels of plasma miR-92a expressions were much lower in SLE patients with down-regulated complement C3,and up-regulated urea nitrogen,creatinine,LDH,ATH (all P＜0 05).Conclusion Down-regulated miR-92a expression in plasma of SLE may be involved in the SLE disease occurrence or development and could be used as a novel potential diagnostic biomarker for SLE.

Objective:To explore the relationship between the degree of devascularization and clinical outcomes after interventional embolization and sclerotherapy for peripheral arteriovenous malformations.Method:A retrospective analysis was conducted on the data of 37 patients with peripheral arteriovenous malformations admitted at Department of Cardiovascular Surgery, China-Japan Friendship Hospital from July 2021 to June 2023. All patients received the treatment of "nidus" and/or outflow veins embolization combined with sclerotherapy injection. Two experienced physicians evaluated the degree of devascularization before and after treatment, and conducted a correlation study with clinical outcomes after follow-up.Result:All 37 patients were symptomatic. Swelling and pain accounted for 75.7% of all the cases. Twenty-six patients received only one procedure, 3 patients received re-interventional treatments. The average follow-up time was（13.3±5.0）months. Clinical symptoms were completely relieved in 14 patients, and partial relief in 22 patients. The overall effective rate was 97%. There were 6 patients with degree of de vascularization<50% during procedure, 16 patients with degree of 50%-75%, and 5 patients with degree of 75%-90%, 10 cases with degree over 90%. Patients with devascularization degrees less than 60% can not achieve clinical symptom relief.Conclusions:There is a positive correlation between the degree of devascularization and clinical outcomes in the interventional embolization and sclerotherapy of peripheral arteriovenous malformations, and 60% of the degree of devascularization can serve as the "threshold" for effectiveness of treatment.

Arabidopsis thaliana is an important and long-established model species for plant molec-ular biology,genetics,epigenetics,and genomics.However,the latest version of reference genome still contains a significant number of missing segments.Here,we reported a high-quality and almost complete Col-0 genome assembly with two gaps(named Col-XJTU)by combining the Oxford Nanopore Technologies ultra-long reads,Pacific Biosciences high-fidelity long reads,and Hi-C data.The total genome assembly size is 133,725,193 bp,introducing 14.6 Mb of novel sequences compared to the TAIR1 0.1 reference genome.All five chromosomes of the Col-XJTU assembly are highly accurate with consensus quality(QV)scores＞60(ranging from 62 to 68),which are higher than those of the TAIR10.1 reference(ranging from 45 to 52).We completely resolved chro-mosome(Chr)3 and Chr5 in a telomere-to-telomere manner.Chr4 was completely resolved except the nucleolar organizing regions,which comprise long repetitive DNA fragments.The Chr1 cen-tromere(CEN1),reportedly around 9 Mb in length,is particularly challenging to assemble due to the presence of tens of thousands of CEN180 satellite repeats.Using the cutting-edge sequencing data and novel computational approaches,we assembled a 3.8-Mb-long CEN1 and a 3.5-Mb-long CEN2.We also investigated the structure and epigenetics of centromeres.Four clusters of CEN180 monomers were detected,and the centromere-specific histone H3-like protein(CENH3)exhibited a strong preference for CEN 180 Cluster 3.Moreover,we observed hypomethylation patterns in CENH3-enriched regions.We believe that this high-quality genome assembly,Col-XJTU,would serve as a valuable reference to better understand the global pattern of centromeric polymorphisms,as well as the genetic and epigenetic features in plants.

Diabetic foot ulcer is a serious and destructive complication of diabetes， with the rates of disability and mortality increasing year by year， which poses a serious threat to human physical and mental health. In the treatment of diabetic foot ulcer with traditional Chinese medicine （TCM）， the combination of syndrome differentiation and overall concept can not only alleviate TCM syndrome but also accelerate wound healing， reduce wound recurrence， delay the further deterioration of diabetic foot ulcer， and decrease the rates of disability and mortality. Modern studies have demonstrated that the difficult healing of diabetic foot ulcer is closely associated with the abnormal distribution of cytokines such as inflammatory cytokines， growth factors， and chemokines. With the deepening of modern medical research on TCM， the treatment of diabetic foot ulcer via regulation of cytokines by Chinese medicinal monomers and prescriptions has become a research focus. This paper summarizes the current research status at home and abroad and draws the following conclusions. ① Sesamol， geniposide， Danggui Buxuetang， and Zizhu ointment can regulate tumor necrosis factor-α （TNF-α）， interleukin （IL）-1， IL-6， IL-10 and other inflammatory cytokines to inhibit wound inflammation. ② Angelicae Dahuricae Radix， salvianolic acid B， Sixiao powder， Badu Shengji ointment （Zhuang medicine）， etc.， regulate vascular endothelial growth factor （VEGF）， platelet-derived growth factor （PDGF）， transforming growth factor （TGF）， epidermal growth factor （EGF） and other growth factors to promote collagen deposition and angiogenesis on wound surface. ③ Paeoniflorin， cryptanshinone， bee venom， and Huiyang Shengji decoction regulate CXC chemokine ligand （CXCL） 1， CXCL2， C-C chemokine ligand （CCL） 2， CCL3， stromal cell-derived factor-1α （SDF-1α）， monocyte chemoattract protein-1 （MCP-1） and other chemokines to reduce inflammatory response and promote neovascularization and wound granulation tissue formation. ④ In the treatment of diabetic foot ulcer， Chinese medicinal monomers and prescriptions have different and complicated mechanisms. The multi-target treatment manner determines that Chinese medicines can act on a variety of cytokines to participate in various stages of wound healing and thus play a therapeutic role. The conclusion above aims to provide ideas for the experimental research and clinical treatment of diabetic foot ulcer with TCM in the future.
