Objective This study was to develop a"Spleen Deficiency Certificate Scale for County Residents"and test its reliability.It was then developed as an objective tool for Chinese medicine evidence and symptoms for the prevention and control of chronic diseases among county residents.Methods The scale was compiled based on the team's previous foundation.The reliability of the scale was evaluated using internal consistency reliability and split-half reliability,while its validity was evaluated using structural validity,content validity,calibration validity,and discriminant validity.Results The study included 213 adults from Lanxi,of whom 155 were tested for intestinal flora.Seven scale entries were identified:Fatigue,fear of cold,bland mouth,loss of appetite,diarrhea,weak bowel movements,and tooth-marked tongue.In the reliability test,Cronbach's alpha coefficient was 0.828 and McDonald's ω coefficient was 0.825.The"stomach pain"and"bloating"entries did not meet the inclusion requirements and were recommended to be deleted.The Spearman-Brown coefficient was 0.839.The exploratory factor analysis of the two common factors explained 61.6%of the cumulative variance.The calibration validity indicated that the ratio of salivary amylase activity before and after acid stimulation was 0.826±0.253 in the group with spleen deficiency.Significant differences(P<0.05)in the genera Dialister,Shigella,Leuconostoc,Photobacterium,Trabulsiella,and Parvimonas between the spleen deficiency group and the non-spleen deficiency group.Conclusion The Spleen Deficiency Scale for County Residents demonstrates good reliability and validity.

Objective:To investigate the eye movement characteristics of non-emotional pictures and emotion-al pictures in college students with different self-rating levels of depression.Methods:The Baker Depression Ques-tionnaire(BDI-2)was used to select 20 college students in high score group(BDI-2 score≥ 18 points)and 20 col-lege students in low score group(BDI-2 score ≤2 points).In experiment 1 the different finding tasks were used to investigate the difference of eye movement features between the two groups when viewing non-emotional pic-tures.In experiment 2 the expression recognition tasks were used to investigate the difference of the eye movement features between the two groups when viewing emotional pictures.Results:The results of experiment 1 showed that when completing the judgment task,the fixation times of each interest area of non-emotional images was smaller in the high score group than in the low score group(P＜0.01).The results of experiment 2 showed that the reaction time was longer to sad faces than to happy faces in the high score group(P＜0.05),and the correct rate to sad faces was higher in the high score group than in the low score group(P＜0.05).For the eye interest area,the first fixation arrival time was earlier in the high score group than in the low score group(P＜0.001),and the first fixa-tion time and total fixation time were shorter in the high score group than in the low score group(Ps＜0.01).Con-clusion:College students with high self-rating level of depression show a decrease of interest when viewing non-e-motional pictures,and show an advantage in processing negative emotional information and avoiding eye gaze when viewing emotional pictures.

The purpose of this study was to explore the protective effect of glycyrrhiza polysaccha-ride on oxidative stress-induced liver cell damage in broiler chickens,and to study its mechanism of action.Primary broiler liver cells cultured in vitro were divided into blank control group,H2 O2 in-duction group,glycyrrhiza polysaccharide group and H2O2+glycyrrhiza polysaccharide group;CCK-8 reagent was used to detect liver cell activity in broiler chickens,JC-1 and DAPI staining kits were used to detect cell apoptosis,relevant kits were used to detect GSH-Px,SOD,CAT,MDA content,and T-AOC levels.qRT-PCR was used to detect antioxidant genes Nrf2,Keap-1,GPx1,SOD,CAT and inflammatory genes TLR4,MyD88,NF-κB,TNF-α、IL-6,IL-1β、IL-4 and IL-10.The results showed that compared with the H2O2 induced group,glycyrrhiza polysaccharide pretreat-ment could significantly enhance liver cell activity and reduce cell apoptosis in broiler chickens;compared with the H2O2 induced group,glycyrrhiza polysaccharide pretreatment could significant-ly increase cell GSH-Px,SOD,CAT,MDA content and T-AOC levels,and inhibit MDA genera-tion;qRT-PCR detection showed that glycyrrhiza polysaccharide could significantly increase the relative expression levels of Nrf2,Keap-1,GPx1,SOD,CAT,IL-4 and IL-10,while significantly re-ducing MyD88,NF-κB,TNF-α,IL-6 and IL-1β.The results indicated that glycyrrhiza polysaccha-ride enhance the activity of antioxidant enzymes by activating the Nrf2 signaling pathway and in-hibit TLR4 signaling pathway transduction,significantly improving oxidative stress damage in broiler liver cells.

Objective To observe the effect of preoperative enteral nutritional support combined with modified Ivor-Lewis surgery for esophageal cancer on lung function and mRNA expression of GATA-binding protein 3(GATA3)and forkhead protein P3(Foxp3)in peripheral blood.Methods Sixty esophageal cancer patients who underwent modified Ivor-Lewis surgery in our hospital from January 2022 to October 2023 were selected and divided into two groups by simple random method.The control group was given conventional diet before operation,and the observation group was given enteral nutrition support before operation.The two groups were compared in terms of nutritional support.Results Both groups showed significantly decreases in one-second exertion expiratory volume/exertion lung volume(FEV1/FVC)(P<0.05),FVC(P<0.05),FEV1(P<0.05)and the levels of peripheral blood GATA3(P<0.05),Foxp3 mRNA(P<0.05)expression compared with those at admission(P<0.05),but no significant differences in pulmonary function(P>0.05),peripheral blood GATA3(P>0.05),and Foxp3 mRNA(P>0.05)expression between them at 1 week postoperatively.Both groups exhibited significantly lower levels of albumin,prealbumin,haemoglobin,transferrin,PNI and body mass and body mass index at admis-sion as compared to those at one week after surgery(P<0.05).The observation group showed significantly higher levels of albumin,prealbumin,haemoglobin,transferrin,and PNI at 1 week postoperatively(P<0.05),but no significant differences in ventilation time,defecation time,drain retention time,hospitalisation time,and compli-cation rate as compared to the control group(P>0.05).Conclusion Preoperative enteral nutritional support combined with modified Ivor-Lewis surgery for esophageal cancer improves postoperative nutritional status,and ren-ders less effect on postoperative lung function and peripheral blood GATA3 and Foxp3 mRNA expression.

Objectives:To explore the clinicopathological characteristics and prognostic risk factors in differentiated thyroid cancer (DTC) patients with lung metastasis.Methods:Patients of differentiated thyroid cancer with lung metastasis in Tianjin Medical University Cancer Institute & Hospital were enrolled from Jan 1, 2010 to Dec 31, 2016. The clinicopathological characteristics and risk factors affecting the prognosis were analyzed retrospectively.Results:A total of 65 DTC patients with lung metastasis were collected in this study, including 56 patients with papillary thyroid carcinoma and 9 patients with follicular thyroid carcinoma; 23 patients died and 42 patients survived. Median follow-up time was 99.4 months. There were 18 males, 47 females. Age 14-73 years, median age 51.0 years. High incidence of DTC lung metastasis was 50-59 years for males and 40-49 years for females. Based on AJCC 8th edition TNM staging, there were 37 patients in stage Ⅱ (age <55 years) and 28 patients in stage Ⅳb (age ≥55 years). The number of 131Ⅰ treatments performed ranged from 1 to 13 times, with a mean of 3.9 times. Firty-five patients were with lung metastasis alone, and 10 patients with lung metastasis and distant metastasis in other organs. Eleven patients suffered from hypoparathyroidism after 131Ⅰ treatment. COX multifactorial regression analysis found that age was independent risk factor affecting prognosis, multiple organs distant metastasis and pathologic subtype were relative risk factors affecting prognosis. There was no correlation between gender, number of 131Ⅰ treatments and poor prognosis. Conclusions:DTC has a high survival even with the occurrence of lung metastasis, but the prognosis is poor when combined with multi-organ metastasis. Age and multiple organ distant metastatic are independent risk factors affecting prognosis.

Objective:To explore the short-term efficacy on 3D printing assisted reconstruction of traumatic digit joint defects using rib and costo-osteochondral autograft.Methods:From August 2022 to July 2023, 7 patients with open digit joint defects had undergone emergency primary debridement and fracture fixation in the Department of Orthopaedics, 988th Hospital of the Joint Logistics Support Force of PLA. Patients with more phalangeal defects that could not be aligned were treated with antibiotic bone cement filling in the emergency surgery. In the second stage surgery, bone cement was removed and transfer of rib cartilage graft was performed to reconstruct the digit joint defect. According to a 1∶1 3D printed hand templates, rib cartilage grafts were crafted to the shape of digit joints, and then spliced together the digit joints and bone defects for fixation. Follow-up X-ray examinations were taken and assessment of the healing status of rib and fractures of phalangeal and metacarpophalangeal bones were carried out according to the Paley fracture healing score. At the outpatient follow-up, assessment of transferred joint movement and evaluation of upper limb function were conducted according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. Visual Analogue Scale (VAS) pain scores were evaluated from the affected digits and donor sites.Results:After reconstructive surgery, all 7 patients had primary healing of the wounds of hand. One patient had fat liquefaction at the donor site, and the rest had primary donor site healing. One patient received further surgery for extensor tendon repair after rib cartilage grafting due to the digital extensor tendon injury. All 7 patients were included in postoperative follow-up for 6-11 months, with an average of 9 months. All patients had excellent fracture healing according to the Paley fracture healing score. At the final follow-up, the extension and flexion of the digit joints were found at 40°-80° (average 56.2°) for proximal interphalangeal joints (4 patients), and 10° in extension and 85° in flexion for metacarpophalangeal joint (1 patient). The range of motion of the thumb interphalangeal joint (2 patients) was 20°-35° (average 27.5°). Hand function was assessed according to Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association and it was found that 3 patients were in excellent, 3 in good and 1 in fair.Conclusion:This study focused on the treatment of traumatic digit joint defects by transfer of individually crafted rib cartilages in reconstruction of the defected digit joint. It significantly improves the appearance and function of the defected digit joints, especially suitable for the irregular defects of phalangeal bones.

For wild natural medicine, unanticipated biodiversity as species or varieties with similar morphological characteristics and sympatric distribution may co-exist in a single batch of medical materials, which affects the efficacy and safety of clinical medication. DNA barcoding as an effective species identification tool is limited by its low sample throughput nature. In this study, combining DNA mini-barcode, DNA metabarcoding and species delimitation method, a novel biological sources consistency evaluation strategy was proposed, and high level of interspecific and intraspecific variations were observed and validated among 5376 Amynthas samples from 19 sampling points regarded as "Guang Dilong" and 25 batches of proprietary Chinese medicines. Besides Amynthas aspergillum as the authentic source, 8 other Molecular Operational Taxonomic Units (MOTUs) were elucidated. Significantly, even the subgroups within A. aspergillum revealed here differ significantly on chemical compositions and biological activity. Fortunately, this biodiversity could be controlled when the collection was limited to designated areas, as proved by 2796 "decoction pieces" samples. This batch biological identification method should be introduced as a novel concept regarding natural medicine quality control, and to offer guidelines for in-situ conservation and breeding bases construction of wild natural medicine.

The anterior cruciate ligament (ACL) injury is a common sports injury that has a significant impact on knee function and patients′ mobility. With the popularity of national fitness campaign in China, the incidence of ACL injury is increasing year by year. Currently, there still lacks clinical standards or guidelines on how to choose appropriate treatment methods, surgical plans and rehabilitation protocols for ACL injury. In order to timely reflect the new treatment concept of ACL injury, standardize its diagnosis and treatment and improve the curative effect, the Sports Medicine Society of Chinese Research Hospital Association and the Editorial Board of Chinese Journal of Trauma organized domestic orthopedic and sports medicine experts to formulate the "clinical evidence-based guideline for the diagnosis and treatment of anterior cruciate ligament injury (2022 version)" based on the level of evidence-based medicine and in compliance with the principle of scientificity, practicability and advancement. The present guideline includes 12 recommendations for the diagnosis, treatment and rehabilitation of ACL injury in order to provide guidance and assistance for the clinical diagnosis and treatment of ACL injury in China.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion 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) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.

Objective:To explore the risk factors influencing the prognosis for patients with hepatocellular carcinoma (HCC) recurrence after liver transplantation and summarize the relevant diagnostic and therapeutic experiences.Methods:The clinicopathological features with diagnosis and treatment plan of 102 recurrent HCC patients fulfilling the Fudan Criteria were compared for survival rate (univariate analysis) and independent prognostic indicators were obtained by Cox multivariate analysis.Results:The 1/3/5-year overall survival rates were 92.2%, 48.6% and 34.6% and the 1/3/5-year survival rates with tumor were 63.2%, 31.0% and 16.7% respectively. Cox regression analysis indicated that patient age, whether tumor can be surgically resected or not and personalized diagnostic & therapeutic plan based upon targeted therapy were independent prognostic factors affecting the overall survival rates and survival rates with tumor.Conclusions:Although HCC recurrence and metastasis after liver transplantation seriously influence patient prognosis, satisfactory outcomes may be obtained for some patients through active, effective and precise managements.
