OBJECTIVE: To investigate the clinical characteristics and prognosis of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). METHODS: Clinical data of 10 patients with PTCL-NOS in Gansu Provincial Hospital from May 2016 to June 2023 were collected. The treatment outcomes were evaluated, and the factors affecting prognosis were analyzed. RESULTS: The median age of onset for the 10 patients was 60.7 (47-75) years, with 7 males and 3 females. Nine cases received chemotherapy, while one case died suddenly after diagnosis, and the median course of chemotherapy was 6.9 (1-13) courses. Assessing the efficacy, 3 patients achieved complete remission (CR) while 7 patients showed progression. Age, sex, lactate dehydrogenase (LDH) level, Ki-67 and the presence of hemophagocytic lymphohistocytosis (HLH) were not statistically correlated with CR rate ( P >0.05). Patients with IPI score 3-5, and Ann Arbor stage III-IV had statistically lower CR rates (both P <0.05). Age, B symptoms, LDH level ,hemoglobin, Ki-67 index and PLR value were not statistically correlated with overall survival (OS) time ( P >0.05). Male, platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, presence of HLH, NLR≥4.05, and LMR <2.81 were statistically correlated with shorter OS (all P <0.05). Among the 10 patients, 3 cases have survived and are still in CR status, while 7 cases have died, with a median survival time of 7.5 (1-85) months. CONCLUSIONS Patients with IPI score 3-5 and Ann Arbor stage III-IV have low CR rate and poor prognosis. The OS of patients who are male, with platelet <150×10⁹/L, IPI score 3-5, Ann Arbor stage III-IV, complication of HLH, NLR≥4.05, and LMR <2.81 is short, and prognosis is poor.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

The synthesis and regulatory mechanism of tanshinones, the key active constituents of Salvia miltiorrhiza, have been a hot topic of research. The paper summarized the research findings on the regulation of tanshinone biosynthesis by transcription factors such as AP2/ERF, bHLH, MYB, bZIP, and WRKY in recent years. The review identifies the existing issues in the transcriptional regulation studies of Salvia miltiorrhiza and discusses the research direction of transcription factors in the regulation of tanshinone biosynthesis, providing a theoretical basis for the further discovery and utilization of functional genes involved in the regulation of tanshinone bioactive constituents.

Objective:To investigate the influencing of preoperative total bilirubin (TBil) on perioperative complications of hepatolithiasis receiving liver resection.Methods:The retrospective cohort study was conducted. The clinical data of 300 patients with hepatolithiasis who were admitted to 2 medical centers from January 2010 to January 2022 were collected. There were 115 males and 185 females, aged (54±13)years. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for comparison between groups. Measurement data with skewed distribution were represented as M( Q1, Q3), and the Mann-Whitney U test was used for comparison between groups. Count data were expressed as absolute numbers, and the chi-square test was used for comparison between groups. Variables with P<0.10 in the univariate analysis were included into the multivariate analysis. Univariate analysis was conducted using the Logistic regression model,and multivariate analysis was conducted using the Logistic stepwise regression model with backward Wald method. Continuous variables were converted into categorical variables based on commonly reported cutoff values when conducting Logistic regression analysis. Results:(1) Comparison of clinical data of patients with different preoperative TBil. Of 300 patients with hepatolithiasis, there were 252 cases with low level of preoperative TBil as 14.4(11.1,19.7)μmol/L, and there were 48 cases with high level of preoperative TBil as 44.0(31.3,59.8)μmol/L. Of the pati-ents with low level of preoperative TBil, neutrophils percentage was 62%±10%, cases with intra-operative blood transfusion was 29, and cases undergoing anatomical liver resection was 166. Of the patients with high level of preoperative TBil, neutrophils percentage was 70%±11%, cases with intraoperative blood transfusion was 22, and cases undergoing anatomical liver resection was 15. There were significant differences in cases classified as>grade 2 of ASA classification, neutrophils percentage, cases with intraoperative blood transfusion and cases undergoing anatomical liver resection between patients with low and high level of preoperative TBil ( t=5.182, χ2=33.669, 18.775, P<0.05). (2) Comparison of perioperative complications of patients with different preoperative TBil. Of the 252 patients with low level of TBil, there were 151 cases with complications including 35 cases of serious complications, there was 1 case with postoperative liver failure, the duration of postoperative hospital stay was 13.0(10.0,16.0)days. Of the 48 patients with high level of TBil, there were 32 cases with complications including 17 cases of serious complications, there were 6 cases with postoperative liver failure, the duration of postoperative hospital stay was 14.0(10.0,18.8)days. There were significant differences in cases with serious complications and cases with postoperative liver failure between patients with low and high level of preoperative TBil ( χ2=13.041, 20.879, P<0.05). (3) Analysis of factors influencing postoperative serious complications in patients undergoing liver resection. Results of multivariate analysis showed that age, body mass index (BMI), preoperative TBil and volume of intraoperative blood loss were independent factors influencing postoperative serious complications in patients undergoing liver resection for hepatolithiasis ( odds ratio=3.852, 2.358, 2.935, 5.135, 95% confidence interval as 1.478?9.979, 1.110?5.009, 1.398?6.158, 2.088?12.626, P<0.05). Conclusions:Patients with high level of preoperative TBil have a significantly increased risk of postoperative serious complications and liver failure who receive liver resection for hepatolithiasis. Age, preoperative BMI, TBil and volume of intraoperative blood loss are independent factors influencing postoperative serious complications in patients undergoing liver resection for hepatolithiasis.

Objective:To investigate the influene of sarcopenia on quality of life in patients with adenocarcinoma of gastroesophageal junction (AEG).Methods:The retrospective cohort study was conducted. The clinicopathological data of 109 patients with AEG who were admitted to Henan Provincial People′s Hospital from January 2019 to December 2022 were collected. There were 63 males and 46 females, aged (63±11)years. All patients underwent 3D laparoscopic assisted radical total gastrectomy+D 2 lymph node dissection. The skeletal muscle content of patient was obtained within 3 days before surgery by using a multi-frequency bioelectrical impedance human body composition analyzer. Observation indicators: (1) clinical characteristics of patients with sarco-penia and non sarcopenia; (2) intraoperative and postoperative conditions in patients with sarco-penia and non sarcopenia; (3) analysis of serious postoperative complications in patients with AEG; (4) preoperative and postoperative quality of life score in patients with sarcopenia and non sarco-penia. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Mann-Whitney U non-parameter rank sum test. Repeated measurement data were analyzed using the repeated ANOVA, and their variances were tested using a spherical test. Univariate analysis was conducted using the Logistic regression model, and multivariate analysis was conducted using the Logistic stepwise regression model. Results:(1) Clinical characteristics of patients with sarcopenia and non sarcopenia. Of 109 patients with AEG, there were 42 cases with sarcopenia and 67 cases with non sarcopenia. The body mass index (BMI), forced expiratory volume in 1 second (FEV1), rate of FEV1/forced vital capacity were (20.3±2.3)kg/m 2, 92%±9%, 79%±11% in patients with sarcopenia, respectively, versus (24.4±2.7)kg/m 2, 97%±9%, 85%±11% in patients with non sarcopenia, showing significant differences in the above indicators between them ( t=8.07, 2.46, 2.77, P<0.05). (2) Intraoperative and postoperative conditions in patients with sarcopenia and non sarco-penia. The volume of intraoperative blood loss, time to postoperative first flatus, duration of post-operative hospital stay, cases with postoperative complications were 208(192, 231)mL, (3.4±0.9)days, (11.4±3.2)days, 26 in patients with sarcopenia, respectively, versus 195(150,215)mL, (2.8±0.7)days, (9.9±1.6)days, 14 in patients with non sarcopenia, showing significant differences in the above indi-cators between them ( Z=-2.14, t=3.25, 3.38, χ2=18.69, P<0.05). (3) Analysis of serious postoperative complications in patients with AEG. Results of multivariate analysis showed that sarcopenia and BMI reduction were independent risk factors influencing serious postoperative complications in patients with AEG ( odds ratio=2.04, 1.98, 95% confidence interval as 1.24-3.36, 1.09-3.60, P<0.05). (4) Pre-operative and postoperative quality of life score in patients with sarcopenia and non sarcopenia. Results of multivariate test in physical function, role function, social function, overall score of patients with sarcopenia and non sarcopenia before surgery, 2 weeks after surgery, 4 weeks after surgery, and 8 weeks after surgery showed that there were significant differences in the temporal effect, intergroup effect and interaction effect of the above indicators between patients with sarcopenia and non sarcopenia ( P<0.05). Results of individual effects showed that there were significant differences in the intergroup effect of the above indicators between patients with sarcopenia and non sarcopenia ( P<0.05). Conclusion:Preoperative sarcopenia increases the risk of severe postoperative complications and reduces the postoperative quality of life in patients with AEG.

OBJECTIVE: To explore the genetic basis for a Chinese pedigree affected with hereditary spastic paraplegia type 30 (HSP30). METHODS: A proband presented at the Second Hospital of Shanxi Medical University in August 2021 was selected as the study subject. The proband was subjected to whole exome sequencing, and candidate variant was verified by Sanger sequencing and bioinformatic analysis. RESULTS: The proband was found to have harbored a heterozygous c.110T>C variant in exon 3 of the KIF1A gene, which can cause substitution of isoleucine by threonine at position 37 (p.I37T) and alter the function of its protein product. The same variant was not found in his parents, elder brother and elder sister, suggesting that it has a de novo origin. Based on the guidelines of the American College of Medical Genetics and Genomics (ACMG), the variant was rated as likely pathogenic (PM2_Supporting+PP3+PS2). CONCLUSION The c.110T>C variant of the KIF1A gene probably underlay the HSP30 in the proband. Above finding has enable genetic counseling for this family.

Objective:The evidence-based and Delphi methods were used to construct the exercise program for hospitalized patients with diabetes foot to provide guidance for clinical practice.Methods:Evidence on exercise management of diabetic foot patients was systematically searched from BMJ Best Practice, UpToDate, Registered Nurses′ Association of Ontario and other domestic and foreign databases and professional association websites. The retrieval period was from the establishment of the database to April 2021. The quality of the included literature was independently evaluated, and the evidence of the literature meeting the quality standards was extracted and summarized to form the first draft of exercise program for inpatients with diabetic foot. After two rounds of Delphi expert letter consultation, the program items were revised, and the final draft of the exercise program for inpatients with diabetic foot suitable for clinical practice was formed.Results:The effective recovery rate of the two rounds of expert correspondence questionnaire both were15/15. The expert authority coefficient was 0.865 and 0.895 respectively. And the Kendall coordination coefficient was 0.232 and 0.291 (both P<0.01). An exercise program for inpatients with diabetic foot had been formed, including 5 modules(exercise evaluation, exercise prescription, exercise monitoring, post-exercise evaluation and exercise management), 12 items and 40 operational items. Conclusions:The exercise program for inpatients with diabetic foot constructed in this study is scientific and clinically applicable, which provide scientific guidance for clinical medical staff to carry out exercise practice.

Objective:To investigate the influencing factors of textbook outcomes in liver surgery (TOLS) after radical resection of gallbladder carcinoma.Methods:The retrospective case-control study was conducted. The clinicopathological data of 530 patients who underwent radical resection of gallbladder carcinoma in 15 medical centers, including the First Affiliated Hospital of Army Medical University et al, from January 2014 to January 2020 were collected. There were 209 males and 321 females, aged (61±10)years. Patients underwent radical resection of gallbladder carcinoma, including cholecystectomy, hepatectomy, invasive bile duct resection, and lymph node dissection. Observation indicators: (1) situations of TOLS; (2) influencing factors of TOLS. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the Mann-Whitney U test. The univariate analysis was conducted using the corresponding statistical methods based on data type, and variables with P<0.10 were included in multivariate analysis. Multivariate analysis was conducted using the Logistic stepwise regression model. Results:(1) Situations of TOLS. All 530 patients underwent radical resection of gallbladder carcinoma, and there were 498 cases achieving R 0 resection, 508 cases without ≥grade 2 intra-operative adverse events, 456 cases without postoperative grade B and grade C biliary leakage, 513 cases without postoperative grade B and grade C liver failure, 395 cases without severe com-plications within postoperative 90 days, 501 cases did not being re-admission caused by severe com-plications within postoperative 90 days. Of the 530 patients, 54.53%(289/530) of patients achieved postoperative TOLS, while 45.47%(241/530) of patients did not achieve postoperative TOLS. (2) Influencing factors of TOLS. Results of multivariate analysis showed that American Society of Anesthesiologists classification >grade Ⅱ, preoperative jaundice, T staging as T3?T4 stage, N staging as N2 stage, liver resection as right hemi-hepatectomy, and neoadjuvant therapy were independent factors influencing TOLS in patients undergoing radical resection of gallbladder carcinoma ( odds ratio=2.65, 1.87, 5.67, 5.65, 2.55, 3.34, 95% confidence interval as 1.22?5.72, 1.18?2.95, 2.51?12.82, 2.83?11.27, 1.41?4.63, 1.88?5.92, P<0.05). Conclusion:American Society of Anesthesiologists classification >grade Ⅱ, preoperative jaundice, T staging as T3?T4 stage, N staging as N2 stage, liver resection as right hemi-hepatectomy, and neoadjuvant therapy are independent factors influencing TOLS in patients undergoing radical resection of gallbladder carcinoma.

AIM: To investigate the expression and correlation of C1q/tumor necrosis factor related protein 9(CTRP9)levels in the serum of patients with different stages of diabetic retinopathy(DR)and diabetic macular edema(DME).METHODS: A total of 135 patients with type 2 diabetes who were admitted to Gansu Provincial Hospital from April 2021 to April 2022 were selected as the experimental group. According to the results of non-mydriatic fundus photography, they were divided into non-DR(NDR)group(n=45), non-proliferative DR(NPDR)group(n=45), proliferative DR(PDR)group(n=45); according to the results of optical coherence tomography, DR patients were divided into DME group(n=51), non-DME group(n=39). In addition, other 45 healthy subjects who matched the age and sex of the experimental group were selected as normal control group. The clinical data and biochemical index test results of subjects in each group were recorded and compared, the correlation between serum CTRP9 level and other biochemical indexes was analyzed, and the risk factors affecting the occurrence of DR and DME were explored.RESULTS: There were significant differences in serum CTRP9 levels among subjects in normal control group, NDR group, NPDR group and PDR group(P<0.001), and normal control group > NDR group > NPDR group > PDR group. There was significant difference in serum CTRP9 level between DME group and non-DME group(P<0.001), and non-DME group > DME group. Spearman rank correlation analysis showed that the level of serum CTRP9 in DR patients was negatively correlated with the course of diabetes(rs=-0.251, P<0.05), the level of serum CTRP9 in DME patients was negatively correlated with fasting blood glucose(FBG)(rs=-0.370, P<0.05)and glycosylated hemoglobin(HbA1c)(rs=-0.421, P<0.05). Logistic multivariate regression analysis showed that the course of diabetes(OR=1.194, 95%CI: 1.068～1.335,P=0.002)and the level of serum CTRP9(OR=0.936, 95%CI: 0.907～0.966,P<0.001)were risk factors for DR. The level of serum CTRP9 was a risk factor affecting the occurrence of DME(OR=0.838, 95%CI: 0.778～0.903, P<0.001).CONCLUSION: The reduction of CTRP9 level is a risk factor for the occurrence of DR and DME, which may be of great significance to the risk assessment of both DR and DME.
