BackgroundThe prevalence of depressive disorder in adolescents is on the rise. There have been studies on the pairwise relations between dysfunctional attitude， negative automatic thoughts， positive coping style and depressive symptoms in the past. However， the impact of the intrinsic relations among dysfunctional attitude， negative automatic thoughts and positive coping style on depressive symptoms is still unclear. ObjectiveTo explore the influence of dysfunctional attitude on adolescent depressive symptoms and examine the action path of negative automatic thoughts and positive coping style on it， in order to provide references for intervention for adolescent patients with depressisve disorder. MethodsThis study involved 162 adolescent patients with depressive disorder， who met the diagnostic criteria for depressive episodes in the International Classification of Diseases， 10th edition （ICD-10） and received treatment in Taiyuan Psychiatric Hospital from October 1， 2022 to October 31， 2023. These patients were evaluated using Self-rating Depression Scale （SDS）， Dysfunction Attitude Scale （DAS）， Positive Coping Style Subscale in Simplified Coping Style Questionnaire（SCSQ） and Automatic Thoughts Questionnaire （ATQ）. Pearson correlation analysis was adopted to examine the correlation among scores of scales above. Model 6 in Process 3.4.1 was adopted to test the acting path of negative automatic thoughts and positive coping style between dysfunctional attitude and adolescent depression symptoms. ResultsA total of 148 adolescent patients with depressive disorder completed an effective questionnaire survey， with a response rate of 91.36%. The direct effect value of dysfunctional attitude on depressive symptoms was 0.423 and the effect size was 63.32%. Negative automatic thoughts and positive coping style affected as acting path between dysfunctional attitude and depressive symptoms， with effect values of 0.156 （accounting for 23.35% of the total effect） and 0.045 （accounting for 6.74% of the total effect） respectively. Meanwhile， negative automatic thoughts and positive coping style affected as a chain reaction pathway between dysfunctional attitude and depressive symptoms， with an effect value of 0.044， accounting for 6.59% of the total effect. ConclusionDysfunctional attitude can not only directly affect the depressive symptoms of adolescent patients with depressive disorder， but also affect the depressive symptoms of adolescent patients with depressive disorder through the independent path or chain path of negative automatic thoughts and positive coping style.

Objective To construct the medical risk comprehensive assessment system based on big data,and to evaluate its consistency and efficiency.Methods Aiming at the current situation of risk assessment of inpatients,based on the means of big data,the medical natural language processing was used to design a medi-cal risk comprehensive assessment system.The system can automatically capture various data of patients,au-tomatically generate the scores by data mining and machine learning technology and send the risk data to med-ical staff,so as to realize the automation and intellectualization.The randomized controlled analysis was used to conduct the manual scoring and machine scoring for included the score scale.The visual risk matrix diagram was automatically generated by comparing the scoring.Results The Kappa values of the scoring system in the included study of the system were as follows:the Kappa value in Caprini scale(surgery)and Padua scale(internal medicine)was 1.00,NNIS Kappa value was 1.00,Nomogram Kappa value was 0.87,Kappa value in the Morse assessment scale/Hendrich model was 0.83,Braden Kappa value was 0.80,ASA 2023 Kappa was 1.00 and NRS 2002 Kappa value was 0.90.The taking time in the machine scoring all were shorter than those in the manual scoring,and the difference was statistically significant(P＜0.05).Conclusion The risk matrix graph constructed by this system could sharply increase the evaluation efficiency and accuracy,which not only provide the accuracy diagnosis and treatment regimen,but also shorten the hospitalization duration and reduce the medical costs.

Objective To observe the effect of tuina on glutamate uptake and synaptic cleft in the spinal dorsal horn of rats with neuropathic pain through astrocyte NDRG2/GLT-1 pathway,and to explore the potential analgesic mechanism of tuina on neuropathic pain.Methods A total of 54 SD rats were randomly divided into naive group,model group and tuina group(n=18).The CCI model was established in the model group,and the tuina group was treated with acupressure at"Weizhong"(BL 40)from the 4th day after CCI model was successfully established for 14 days.The changes of paw withdrawal threshold at different time points were observed to evaluate the analgesic effect of tuina.Immunofluorescence was used to observe the co-expression of NDRG2?GLT-1 and astrocytes in the spinal dorsal horn.The mRNA levels of NDRG2 and GLT-1 in astrocytes were detected by quantitative real time polymerase chain reaction.The concentrations of glutamate in synaptic cleft were measured by liquid chromatography coupled to tandem mass spectrometry.The width of the synaptic cleft was observed by transmission electron microscopy.Results Compared with the naive group,the paw withdrawal threshold in the CCI group decreased continuously(P<0.01).The number of NDRG2 and GFAP co-labeling positive cells in the spinal dorsal horn increased significantly(P<0.01),and the number of GLT-1 and GFAP co-labeled positive cells was significantly reduced(P<0.01).NDRG2 mRNA expression was up-regulated and GLT-1 mRNA expression decreased in astrocytes(P<0.01).The concentrations of glutamate increased significantly(P<0.01);The synaptic cleft was significantly narrowed(P<0.05).After tuina intervention,the above trend was significantly reversed.Compared with the model group,the paw withdrawal threshold of the tuina group increased from 11 days after CCI(P<0.01),the number of NDRG2 and GFAP co-labeling positive cells in the spinal dorsal horn was significantly reduced(P<0.01),and the number of GLT-1 and GFAP co-labeled positive cells increased significantly(P<0.01);down-regulated the expression of NDRG2 mRNA and restored GLT-1 mRNA expression in astrocytes(P<0.01);decreased glutamate concentration in synaptic cleft(P<0.05),the synaptic cleft was relatively widened(P<0.05).Conclusion Tuina alleviates pain in CCI rats at the spinal cord level possibly by promoting the uptake of glutamate by NDRG2/GLT-1 pathway in astrocytes,restoring the width of synaptic cleft and reversing synaptic plasticity.

Objective To explore the association between R611H(G/A,rs734312)variation of WFS1 gene and early-onset type 2 diabetes mellitus(T2DM).Methods A total of 181 Chinese patients with early-onset T2DM(T2DM group)and 196 non-diabetic controls(NC group)were enrolled in this study.The rs734312 variation was detected by PCR-direct sequencing.Genotypic and allelic frequencies of rs734312 and clinical variables were compared and analyzed between the two groups.Results Compared with the NC group,the frequencies of AA genotype and A allele in R611H(G→A)variation were significantly elevated in the early-onset T2DM group,AA vs GA+GG(OR 1.720,95%CI 1.100～2.680,P<0.05).A vs G(OR 1.500,95%CI 1.020～2.220,P<0.05).The remarkable differences of frequencies of genotype and allele in rs734312(G/A)were observed between Asians(China,Japan and Korea)and Caucasians(Denmark,Britain,Spain,France and Russia,P<0.01 for each).Compared with AA genotype,fasting and 2 hours postprandial insulin(FIns and 2 hIns)as well as HOMA-β were significantly rise in GG+GA genotype carriers of early-onset T2DM group(P<0.05).Conclusions The a allele of rs734312 in WFS1 may be a risk factor for early-onset T2DM in Chinese population,and the variation might be a potential genetic marker for predicting the islet β-cell dysfunction in early-onset T2DM in Chinese population.

Objective To investigate the efficacy and safety of the 12-week regimen with sofosbuvir and coblopasvir hydrochloride in the treatment of chronic hepatitis C (CHC) in northwest China. Methods This study enrolled 101 patients with CHC of any genotype who received sofosbuvir (400 mg) combined with coblopasvir hydrochloride (60 mg) for 12 weeks in The First Affiliated Hospital of Air Force Medical University, The Second Affiliated Hospital of Air Force Medical University, The Second Affiliated Hospital of Xi'an Jiaotong University, and Baoji Central Hospital from July 1 to December 31, 2021, among whom 13 had liver cirrhosis and 88 did not have live cirrhosis. Other antiviral drugs such as ribavirin were not added regardless of the presence or absence of liver cirrhosis or the genotype of CHC. Related clinical data ere extracted, including HCV RNA quantification and liver biochemical parameters at baseline, at week 12 of treatment, and at 12 weeks after drug withdrawal. The primary endpoints were sustained virologic response at 12 weeks after the end of treatment (SVR12) and safety at week 12 of treatment, and the secondary endpoint was the effect of the 12-week treatment on liver biochemical parameters. The non-normally distributed continuous data were expressed as M ( P 25 - P 75 ), and the Mann-Whitney U test was used for comparison between groups. Results A total of 101 patients were included in the analysis, among whom there were 55 male patients (54.5%) and 46 female patients, and the median age was 53 years. Among these patients, 12.8% had liver cirrhosis, 1.0% had liver cancer, 3.0% were treatment-experienced patients, and 3.0% had type 2 diabetes. As for genotype distribution, 8% had CHC genotype 1, 60% had CHC genotype 2, 19% had CHC genotype 3, and 6% had CHC genotype 6, and genotype was not tested for 7% of the patients. After 12 weeks of treatment, all 101 patients had a HCV RNA level of below the lower limit of detection and an SVR12 rate of 100%, with a significant reduction in the serum level of alanine aminotransferase (ALT) from baseline to week 12 of treatment ( P < 0.05). Among these patients, 22.7% had concomitant medications such as atorvastatin calcium, aspirin, metformin, nifedipine, bicyclol, and compound glycyrrhizin. The incidence rate of adverse events was 16.8%, and fatigue (12.9%) was the most common adverse event. Conclusion The 12-week treatment with sofosbuvir and coblopasvir hydrochloride can obtain high SVR12 in CHC patients in northwest China and has good antiviral safety, with a significant improvement in abnormal serum ALT at week 12 of treatment.

Objectives:To investigate the clinical and genetic features of young Chinese patients with myeloproliferative neoplasms (MPN) .Methods:In this cross-sectional study, anonymous questionnaires were distributed to patients with MPN patients nationwide. The respondents were divided into 3 groups based on their age at diagnosis: young (≤40 years) , middle-aged (41-60 years) , and elderly (>60 years) . We compared the clinical and genetic characteristics of three groups of MPN patients.Results:1727 assessable questionnaires were collected. There were 453 (26.2%) young respondents with MPNs, including 274 with essential thrombocythemia (ET) , 80 with polycythemia vera (PV) , and 99 with myelofibrosis. Among the young group, 178 (39.3%) were male, and the median age was 31 (18-40) years. In comparison to middle-aged and elderly respondents, young respondents with MPN were more likely to present with a higher proportion of unmarried status (all P<0.001) , a higher education level (all P<0.001) , less comorbidity (ies) , fewer medications (all P<0.001) , and low-risk stratification (all P<0.001) . Younger respondents experienced headache (ET, P<0.001; PV, P=0.007; MF, P=0.001) at diagnosis, had splenomegaly at diagnosis (PV, P<0.001) , and survey (ET, P=0.052; PV, P=0.063) . Younger respondents had fewer thrombotic events at diagnosis (ET, P<0.001; PV, P=0.011) and during the survey (ET, P<0.001; PV, P=0.003) . JAK2 mutations were found in fewer young people (ET, P<0.001; PV, P<0.001; MF, P=0.013) ; however, CALR mutations were found in more young people (ET, P<0.001; MF, P=0.015) . Furthermore, mutations in non-driver genes (ET, P=0.042; PV, P=0.043; MF, P=0.004) and high-molecular risk mutations (ET, P=0.024; PV, P=0.023; MF, P=0.001) were found in fewer young respondents. Conclusion:Compared with middle-aged and elderly patients, young patients with MPN had unique clinical and genetic characteristics.

Objective:To observe any therapeutic effect of repeated transcranial direct current stimulation (tDCS) on rats modeling neuropathic pain and explore possible mechanisms.Methods:Forty adult male Sprague-Dawley rats were randomly divided into a normal group ( n=10), a sham operation group ( n=10), a treatment group ( n=10) and a sham treatment group ( n=10). A model of chronic constriction injury of the sciatic nerve was established in the latter two groups. Fourteen days after the modeling, the treatment group was given tDCS for 8 consecutive days, while the sham treatment group received sham stimulation, and the other 2 groups did not receive any intervention. Von Frey and hotplate tests were used to test the rats′ pain thresholds 1 day before, as well as 14 and 22 days after the surgery (i.e., 8 days after the end of the treatment). Spinal cord tissue samples were taken to detect the protein expressions of N-methyl-D-aspartic acid receptor 2B, gamma-aminobutyric acid receptor types A (GABA a-R) and B (GABA b-R) using western blotting. Results:On the 14th day after the operation the average 50% MWT and WTL values of the sham treatment and treatment groups had decreased significantly compared with the sham operation group. By the 22nd day the average 50% MWT and WTL values of the treatment group were significantly higher than those of the sham treatment group, but there was no significant change in the treatment group′s average WTL between the 21st and 22nd days. On the 22nd day after the operation the average NR2B-NMDA-R level of the sham treatment group were significantly higher than that of the sham operation group, while the average GABA a-R and GABA b-R levels were significantly lower. At the same time point the treatment group′s average NR2B-NMDA-R level had decreased significantly compared to the sham treatment group, while the average GABA a-R level had increased significantly. There was no significant difference in average GABA b-R level between the treatment group and the sham treatment group at that point. On the 22nd day there was also no significant difference in the average NR2B-NMDA-R level between the treatment group and the sham operation group. Conclusions:Repeated tDCS can effectively relieve neuropathic pain. The relief of hyperalgesia is more significant than that of mechanical allodynia. A possible mechanism may be the down-regulation of spinal NR2B-NMDA-R to normal levels and modest up-regulation of GABA a-R.

Objective:To study the types of pathogenic gene mutations and their main clinical characteristics in children with glucose-6-phosphate dehydrogenase (G6PD) deficiency in Zunyi area.Methods:Children with clinical manifestations of "yellow staining" or "suspected yellow staining" who were admitted to Guizhou Children's Hospital, Affiliated Hospital of Zunyi Medical University, from September 13, 2018 to September 13, 2020 were selected for G6PD gene mutation detection by multicolor probe melting curve analysis, and the pathogenic gene mutation types and clinical characteristics of children with G6PD deficiency were analyzed.Results:The results of G6PD gene mutation detection showed that among the 1 740 children tested, 119 were positive for gene mutation, and the positive detection rate was 6.84%. The proportion of male infants was higher than that of female infants, and the difference was statistically significant (91 males and 28 females, χ 2 = 15.10, P < 0.001); infancy accounted for 63.87% (76/119), and early childhood accounted for 18.49% (22/119). A total of 11 known pathogenic gene mutation types and 1 unknown mutation were detected. Among the top 4 pathogenic gene mutations, the overall was c.1024 C>T, c.1376 G>T, c.1388 G>A and c.95 A>G, male was c.1376 G>T, c.1388 G>A, c.1024 C>T and c.95 A>G; female was c.1024 C>T, c.95 A>G, c.1388 G>A and c.519 C>T. Among the 119 children with G6PD gene mutation, 90 cases had varying degrees of jaundice, including 36 cases of severe and more severe jaundice (including 2 cases of extremely severe neonatal bilirubin encephalopathy), and 54 cases of mild to moderate jaundice; 37 cases had anemia of different degrees, including 6 cases of mild anemia, 12 cases of moderate anemia, and 19 cases of severe or more severe anemia (including 1 case of extremely severe anemia). Conclusions:There are 12 types of gene mutations in children with G6PD deficiency in Zunyi area, and the most common mutation types are c.1024 C>T, c.1376 G>T, c.1388 G>A and c.95 A>G. Children with G6PD deficiency are often accompanied by varying degrees of jaundice and anemia.

Objective:To compare the use of continuous constant negative pressure drainage and intermittent suction mode drainage in abdominal wall angioplasty to minimize the impact of complications.Methods:From May 2017 to August 2019, the Department of Medical Cosmetology and Plastic Surgery, Wuhan Third Hospital treated 76 female patients after expanded flap repair, aged 27-35 years, with an average age of 30.5±14.2 years, and 58 female patients after abdominal wall plasty, aged 38-55 years, with an average age of 47.8±7.8 years. They were divided into intermittent negative pressure drainage group and continuous negative pressure drainage group. The negative pressure values in different intervals were set according to the type of operation. The drainage volume, drainage time, incidence of hematoma, subcutaneous effusion, flap necrosis rate, primary wound healing rate and drainage related bleeding were recorded and compared between the two groups.Results:After expanded flap repair in 38 cases, flap necrosis occurred in 1 case and hematoma in 3 cases; After abdominal wall plasty in 29 cases, flap necrosis occurred in 0 cases and hematoma in 1 case. The primary healing of incision was higher ( P<0.05), the drainage volume was larger, but the drainage time was shorter ( P<0.05), and no bleeding related to drainage was observed. The effect of monitoring drainage was positively correlated with the effect of operation. Conclusions:Continuous and constant negative pressure drainage is related to the prognosis of patients undergoing expansion flap repair and abdominal wall plasty. It is helpful to improve the effect of plastic surgery and the quality of nursing work. It is an effective method for nursing management after plastic surgery.
