ObjectiveTo explore the potential mechanism of Banxia Xiexin Decoction （半夏泻心汤， BXD） in the treatment of diabetic gastroparesis （DGP）. MethodsA total of 29 SD rats were randomly divided into four groups， blank group （5 rats） and model group， BXD group and metformin group （8 rats in each group）. Except for the blank group， rats were administered intraperitoneally with 1% streptozotocin （STZ） solution and were fed a high-sugar， high-fat diet to establish the DGP rat model. After successful modeling， the BXD group was treated with BXD at 6.68 g/（kg·d） by gavage， the metformin group was treated with metformin hydrochloride at 105 mg/（kg·d） by gavage， and the blank group and the model group were treated with normal saline at 6.68 ml/（kg·d） by gavage， for 8 weeks. After the last administration， fasting blood glucose （FBG）， glycated hemoglobin （HbA1c）， total cholesterol （TC）， triglycerides （TG） were measured and gastric emptying rate was calculated. ELISA was used to detect the levels of gastrointestinal hormones motilin （MTL） and gastrin （GAS）， as well as inflammatory factors including tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， interleukin-1β （IL-1β） and interleukin-10 （IL-10） in gastric tissue. Oil red O staining was performed to observe liver pathological morphology. Hematoxylin and eosin （HE） staining was used to observe gastric antrum tissue morphology. Immunofluorescence staining was used to detect liver X receptor α （LXRα） levels in the liver. Western Blot was used to detect the protein levels of LXRα in liver tissue， and of janus kinase 2 （JAK2）， phospho-janus kinase 2 （p-JAK2）， signal transducer and activator of transcription 3 （STAT3） and phospho-signal transducer and activator of transcription 3 （p-STAT3） in gastric antrum tissue. Quantitative real-time polymerase chain reaction （qPCR） was used to measure the mRNA expression of LXRα in liver tissue and JAK2， STAT3 in gastric antrum tissue. ResultsCompared with the blank group， the model group showed significant hepatic fatty degeneration， gastric antrum tissue structure destruction， and increases in FBG， HbA1c， TC， and TG levels； the average fluorescence intensity， protein level， and mRNA expression of LXRα in liver tissue were reduced； the gastric emptying rate and gastric tissue GAS and MTL levels decreased； inflammatory factors including TNF-α， IL-6， IL-1β in gastric tissue increased， IL-10 decreased； in gastric antrum tissue， the mRNA expression of p-JAK2/JAK2， p-STAT3/STAT3， and JAK2 and STAT3 increased （P＜0.01）. Compared with the model group， both the BXD group and the metformin group showed improved liver and gastric antrum tissue pathology； FBG， HbA1c， TC， and TG levels decreased， while LXRα fluorescence intensity， protein level， and mRNA expression in liver tissue significantly increased； the gastric emptying rate and the levels of GAS and MTL in gastric tissue were markedly higher； the levels of TNF-α， IL-6， and IL-1β decreased， whereas IL-10 levels increased， p-JAK2/JAK2， p-STAT3/STAT3， and the mRNA expression of JAK2 and STAT3 in gastric antrum tissue decreased （P＜0.05 or P＜0.01）. The BXD group showed higher level than the metformin group in FBG， HbA1c， and TG levels， lower level in gastric emptying rate and gastric tissue GAS content， and higher level in gastric tissue TNF-α， IL-6， IL-1β levels； there was also a decrease in IL-10 levels， and a reduction in LXRα fluorescence intensity and mRNA expression in liver tissue， as well as in p-JAK2/JAK2 levels in gastric antrum tissue （P＜0.05 or P＜0.01）. ConclusionBXD can reduce blood glucose and lipid levels in DGP model rats while improving gastric function and alleviating gastric tissue inflammation. Its mechanism may be related to the regulation of LXRα expression in liver tissue and the JAK2/STAT3 pathway in gastric antrum tissue.

The gut microbiota regulates intestinal nutrient absorption, participates in modulating host glucolipid metabolism, and contributes to ameliorating glucolipid metabolism disorder. Dysbiosis of the gut microbiota can compromise the integrity of the intestinal mucosal barrier, induce inflammatory responses, and exacerbate insulin resistance and abnormal lipid metabolism in the host. Dangua Humai Oral Liquid, a hospital-developed formulation for regulating glucolipid metabolism, has been granted a national invention patent and demonstrates significant clinical efficacy. This study aimed to investigate the effects of Dangua Humai Oral Liquid on gut microbiota and the intestinal mucosal barrier in a mouse model with glucolipid metabolism disorder. A glucolipid metabolism disorder model was established by feeding mice a high-glucose and high-fat diet. The mice were divided into a normal group, a model group, and a treatment group, with eight mice in each group. The treatment group received a daily gavage of Dangua Humai Oral Liquid(20 g·kg~(-1)), while the normal group and model group were given an equivalent volume of sterile water. After 15 weeks of intervention, glucolipid metabolism, intestinal mucosal barrier function, and inflammatory responses were evaluated. Metagenomics and untargeted metabolomics were employed to analyze changes in gut microbiota and associated metabolic pathways. Significant differences were observed between the indicators of the normal group and the model group. Compared with the model group, the treatment group exhibited marked improvements in glucolipid metabolism disorder, alleviated pathological damage in the liver and small intestine tissue, elevated expression of recombinant claudin 1(CLDN1), occluding(OCLN), and zonula occludens 1(ZO-1) in the small intestine tissue, and reduced serum levels of inflammatory factors lipopolysaccharides(LPS), lipopolysaccharide-binding protein(LBP), interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α). At the phylum level, the relative abundance of Bacteroidota decreased, while that of Firmicutes increased. Lipid-related metabolic pathways were significantly altered. In conclusion, based on the successful establishment of the mouse model of glucolipid metabolism disorder, this study confirmed that Dangua Humai Oral Liquid effectively modulates gut microbiota and mucosal barrier function, reduces serum inflammatory factor levels, and regulates lipid-related metabolic pathways, thereby ameliorating glucolipid metabolism disorder.

OBJECTIVE: To compare the effects of bilateral vertebral puncture guided by an angle-adjustable linear laser auxiliary device versus free-hand bilateral vertebral puncture. METHODS: A retrospective analysis was conducted on the clinical data of 47 patients who underwent thoracolumbar percutaneous kyphoplasty(PKP) from July 2022 to July 2023. All patients received bilateral percutaneous kyphoplasty, among whom 27 cases underwent conventional free-hand puncture (conventional puncture group) and 20 cases underwent puncture guided by a laser auxiliary device (auxiliary puncture group). In the conventional puncture group, there were 11 males and 16 females, with an average age of (69.6±5.1) years and a disease duration of (6.5±3.8) days;the fractured vertebrae were T₁₁-T₁₂ in 13 cases and L₁-L₂ in 14 cases. In the auxiliary puncture group, there were 7 males and 13 females, with an average age of (70.8±5.6) years and a disease duration of (6.4±3.8) days;the fractured vertebrae were T₁₁-T₁₂ in 7 cases and L₁-L₂ in 13 cases. The operation time, total blood loss, intraoperative fluoroscopy times, fluoroscopy duration, radiation dose, puncture success rate, and surgical complications were compared between the two groups. The visual analogue scale (VAS) was used to evaluate low back pain before surgery, 2 days after surgery, and 1 year after surgery. RESULTS: All patients achieved successful puncture, with good postoperative wound healing and no complications. The operation time of the auxiliary puncture group was (12.1±2.6) minutes, which was shorter than that of the conventional puncture group (14.1±2.8) minutes. The total blood loss of the auxiliary puncture group was (228.5±35.8) ml, less than that of the conventional puncture group (257.0±48.3) ml. The fluoroscopy times, fluoroscopy duration, and radiation dose of the auxiliary puncture group were (5.4±1.3) times, (15.9±3.3) seconds, and (159.4±37.4) μSv, respectively, all lower than those of the conventional puncture group (6.4±1.6) times, (18.8±4.6) seconds, (192.2±48.5) μSv, with statistically significant differences(P<0.05). There were no statistically significant differences in low back VAS scores between the two groups before surgery, 2 days after surgery, or 1 year after surgery(P>0.05). CONCLUSION Both laser auxiliary device-guided vertebral puncture and free-hand vertebral puncture have high success rates and similar postoperative curative effects. However, the laser auxiliary device-guided puncture has shorter operation time, less blood loss, and lower radiation hazard.

BACKGROUND:In recent years,computer-assisted navigation has gradually attracted attention in the medical field.Some scholars have reported that the clinical effects of computer navigation in total knee arthroplasty vary.To explore the clinical effect of the new generation of Brainlab Knee 3 navigation system,this study is conducted. OBJECTIVE:To analyze the application effect of computer navigation system(Brainlab Knee 3)combined with gap balance technology in total knee arthroplasty. METHODS:A total of 71 patients received total knee arthroplasty at the Department of Joint Surgery of Dalian Second People's Hospital from November 2020 to May 2021.In the navigation group,35 patients underwent total knee arthroplasty by computer navigation combined with gap balance.In the traditional group,36 patients underwent osteotomy with traditional surgical instruments.The difference between medial and lateral joint spaces,knee range of motion,hospital for special surgery knee score,hip-knee-ankle angle,deviation values of coronal femoral component angle,coronal tibial component angle,and sagittal tibial component angle were compared between the two groups. RESULTS AND CONCLUSION:(1)In the navigation group,the differences of intraoperative medial and lateral joint gap at knee extension 0,1,and 2 mm were found in 19,14,and 2 cases,respectively.The gap difference was 0 mm in 18 cases,1 mm in 15 cases and 2 mm in 2 cases at 90° degree knee flexion.In the traditional group,the gap difference at knee extention was 0 mm in 10 cases,1 mm in 20 cases,and 2 mm in 6 cases.The gap difference at 90 degree knee flexion was 0 mm in 10 cases,1 mm in 15 cases and 2 mm in 8 cases.(2)The operation time in the navigation group was longer than that in the traditional group(P<0.05),and two patients in the navigation group developed lower limb intermuscular vein thrombosis after surgery,and none of the patients in the traditional group had complications.(3)The range of motion between the two groups increased significantly at 6 and 12 months after surgery,and the range of motion in the navigation group was higher than that in the traditional group(P<0.05).(4)At 12 months after surgery,the hospital for special surgery knee scores of both groups increased significantly,and the hospital for special surgery knee score in the navigation group was higher than that in the traditional group(P<0.05).(5)At 6 months after surgery,the deviation values of hip-knee-ankle angle,coronal femoral component angle,coronal tibial component angle,and sagittal tibial component angle of navigation group were significantly lower than those in the traditional group(P<0.05).(6)The results showed that computer navigation technique combined with gap balance in total knee arthroplasty had advantages in postoperative range of motion,lower limb alignment and the accuracy of tibial prosthesis component position,and joint function recovered well.

Objective:To evaluate the effects of antibiotics alone and combined with Longqing tablets and antibiotics on stent-related symptoms (SRS), urinary tract infection (UTI), and quality of life in patients who underwent ureteroscopic lithotripsy (URL) with indwelling ureteral stents.Methods:The clinical data of 160 patients who underwent URL with indwelling ureteral stents in the Department of Urology, Xuanwu Hospital, Capital Medical University from January 2022 to December 2023 were retrospectively analyzed. According to the postoperative application of antibiotics and Longqing tablets, they were divided into two groups: control group and observation group, with 80 cases in each group. The control group took Levofloxacin tablets orally, and the observation group took Longqing tablets combined with Levofloxacin tablets orally. The SRS of the two groups was compared according to the degree of urinary tract irritation symptoms, low back pain, and dysuria. UTI was evaluated by the incidence of fever, hematuria, pyuria, positive rate of urine culture, and specific bacterial classes. The Chinese version of the ureteral stent symptom questionnaire (USSQ) and the quality of life score were evaluated in the two groups. Normally distributed quantitative data were expressed as mean ± standard deviation ( ± s), and the t-test was used for comparison between groups; non-normally distributed quantitative data were expressed as median (interquartile range) [ M( Q1, Q3)], and the non-parametric test was used for comparison between groups. Count data were expressed as the number of cases and percentage, and the Chi-square test was used for comparison between groups. Results:Among the 160 patients, 141 (88.13%) developed SRS, including 71 cases (88.75%) in the control group, and 70 cases (87.50%) in the observation group, there was no significant difference between the two groups ( P=0.724). In terms of SRS, the urinary tract irritation symptom scores [3.0 (1.0, 5.0) points vs 5.0 (3.0, 7.0) points], low back pain scores [1.5 (1.0, 2.0) points vs 2.5 (2.0, 3.0) points] and dysuria scores [1.5 (1.0, 2.0) points vs 3.5 (2.5, 4.0) points] of the observation group were significantly lower than those of the control group, the differences were statistically significant ( P<0.05). The Chinese version of USSQ showed that the urinary tract symptoms of the observation group were significantly relieved compared with the control group [15(12, 19) points vs 22 (15, 28) points], and the difference was statistically significant ( P=0.037). In terms of UTI, the incidence of fever (6.25% vs 7.50%), the incidence of hematuria (20.00% vs 22.50%), the incidence of pyuria (30.00% vs 33.75%), and positive rate of urine culture (11.25% vs 15.00%) between the two groups were not statistically significant ( P> 0.05), but the number was reduced to a certain extent. There was no statistically significant difference in the scores of physiological function, emotional function and social function between the two groups before surgery ( P> 0.05); however, the scores of the above three items in both groups were improved 2 weeks after surgery, and the improvement of the observation group was significantly higher than that of the control group, with statistical significance ( P<0.01). Conclusion:Longqing tablets combined with antibiotics are more effective in improving SRS in patients who receive URL and have indwelling ureteral stents than antibiotics alone, and can prevent UTI and improve the quality of life to a certain extent.

Objective To study the expression levels of serum complement C1q/tumor necrosis factor-related protein 6(CTRP6)in women in early pregnancy and to explore its relationship with gestational diabetes mellitus(GDM).Methods Women at the Second Affiliated Hospital of Zhengzhou University from March 2021 to March 2022 were prospectively and consecutively selected from 10 to 13 weeks gestation for outpatient obstetric check-ups.The age,height,weight,and time of last menstruation of pregnant women were collected,and the levels of total cholesterol(TC),triglyceride(TG),high density lipoprotein(HDL),low density lipoprotein(LDL),fasting plasma glucose(FPG),glycosylated hemoglobin(HbA1c),fasting insulin(FINS)and CTRP6 were measured in early pregnancy,and the pre-pregnancy body mass index(BMI),baseline BMI,prenatal BMI,and homeostatic model assessment of insulin resistance(HOMA-IR)were calculated.All pregnant women underwent a 75g oral glucose tolerance test at 24-28 weeks of gestation and were divided into GDM group and normal glucose tolerance(NGT)group according to the test results.The clinical data and laboratory indexes of the two groups in early pregnancy were compared,and the correlation between serum CTRP6 and various indexes in early pregnancy and its relationship with GDM were analyzed.Results A total of 213 maternal cases were enrolled,and 203 cases were completed for follow-up.Among them,52 mothers were diagnosed with GDM,with a GDM prevalence rate of 25.62%.Serum CTRP6,age,pre-pregnancy BMI,baseline BMI,antenatal BMI,TC,LDL,FPG,HbA1c,FINS,and HOMA-IR were higher in GDM group compared to NGT group,with a statistically significant difference(P<0.05).CTRP6 in early pregnancy was positively correlated with age,pre-pregnancy BMI,baseline BMI,prenatal BMI,TG,LDL,FPG,HbA1c,FINS,HOMA-IR,and negatively correlated with HDL(P<0.05).After correcting for age,BMI,glycolipid metabolism index and HOMA-IR,CTRP6 in early pregnancy remained an independent factor in the development of GDM.Conclusion Elevated serum CTRP6 in early pregnancy is associated with GDM and is an independent risk factor for GDM.

ObjectiveTo explore the intervention effect and molecular mechanism of Dabufei decoction in Dunhuang formula combined with cisplatin on Lewis lung adenocarcinoma-bearing mice. MethodFifty C57BL/6J mice were used， with 10 randomly assigned to the blank group （without modeling）， and 40 subcutaneously inoculated with Lewis cells to establish a Lewis lung adenocarcinoma-bearing mouse model. These 40 mice were randomly divided into the following four groups （with 10 mice in each group）： Model group （equal volume of physiological saline）， cisplatin group （5 mg·kg^-1）， Dabufei decoction group （14.35 g·kg^-1·d^-1）， and Dabufei decoction combined with cisplatin group （Dabufei decoction 14.35 g·kg^-1·d^-1 + cisplatin 5 mg·kg^-1）. Each group was treated continuously for 14 days. The general condition of the mice was observed， body weight changes were recorded， and the tumor inhibition rate， spleen index， and thymus index were calculated. Peripheral blood white blood cell （WBC）， platelet （PLT）， and hemoglobin （HGB） were detected by routine blood tests. Flow cytometry was used to detect the expression of CD4⁺CD25⁺FoxP3⁺ regulatory T cells （Treg） and natural killer （NK） cells in the spleen. Western blot and real-time quantitative polymerase chain reaction （Real-time PCR） were used to determine the expression of proteins and mRNA related to the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway in tumor tissues. ResultCompared with the blank group， the model group showed decreased body weight （P<0.05）， spleen index， and thymus index （P<0.05）， decreased percentage of NK cells in the spleen （P<0.05）， increased percentage of Treg cells （P<0.05）， and decreased counts of WBC， PLT， and HGB （P<0.05）. Compared with the model group， the Dabufei decoction group exhibited significant tumor growth inhibition， increased body weight， and reduced tumor weight （P<0.05）， increased percentage of NK cells （P<0.05）， decreased proportion of Treg cells （P<0.05）， and increased counts of WBC， PLT， and HGB （P<0.05）. In the cisplatin group， tumor growth was significantly inhibited， body weight significantly decreased （P<0.05）， and tumor weight significantly reduced （P<0.05）. The spleen index and thymus index decreased （P<0.05）， and the percentage of Treg cells significantly decreased （P<0.05）. The counts of WBC， PLT， and HGB significantly decreased （P<0.05）. In the Dabufei decoction combined with cisplatin group， tumor growth was significantly inhibited， and tumor weight significantly reduced （P<0.05）. The levels of phosphorylated PI3K， Akt， and mTOR proteins and mRNA in tumor tissues were significantly reduced in all medication groups （P<0.05）. Compared with the cisplatin group， the Dabufei decoction combined with cisplatin group showed significantly inhibited tumor growth， reduced tumor weight （P<0.05）， increased body weight （P<0.05）， increased spleen index and thymus index （P<0.05）， increased percentage of NK cells （P<0.05）， decreased percentage of Treg cells （P<0.05）， significantly increased counts of WBC， PLT， and HGB （P<0.05）， and reduced levels of phosphorylated PI3K， Akt， and mTOR and their mRNA （P<0.05）. ConclusionDabufei decoction combined with cisplatin has a synergistic effect with reduced toxicity， effectively regulating immune function， increasing the proportion of NK cells， reducing the proportion of Treg cells， improving bone marrow suppression， and downregulating the PI3K/Akt/mTOR signaling pathway to inhibit tumor growth in Lewis lung adenocarcinoma-bearing mice.

BACKGROUND:Trauma-induced coagulopathy(TIC)due to serious injuries significantly leads to increased mortality and morbidity among elderly patients.However,the risk factors of TIC are not well elucidated.This study aimed to explore the risk factors of TIC in elderly patients who have major trauma. METHODS:In this retrospective study,the risk factors for TIC in elderly trauma patients at a single trauma center were investigated between January 2015 and September 2020.The demographic information including gender,age,trauma parts,injury severity,use of blood products,use of vasopressors,need of emergency surgery,duration of mechanical ventilation,length of stay in the intensive care unit(ICU)and hospital,and clinical outcomes were extracted from electric medical records.Multivariate logistic regression analysis was performed to differentiate risk factors,and the performance of the model was evaluated using receiver operating characteristics(ROC)curves. RESULTS:Among the 371 elderly trauma patients,248(66.8%)were male,with the age of 72.5±6.8 years,median injury severity score(ISS)of 24(IQR:17-29),and Glasgow coma score(GCS)of 14(IQR:7-15).Of these patients,129(34.8%)were diagnosed with TIC,whereas 242(65.2%)were diagnosed with non-TIC.The severity scores such as ISS(25[20-34]vs.21[16-29],P<0.001)and shock index(SI),(0.90±0.66 vs.0.58±0.18,P<0.001)was significantly higher in the TIC group than in the non-TIC group.Serum calcium levels(1.97±0.19 mmol/L vs.2.15±0.16 mmol/L,P<0.001),fibrinogen levels(1.7±0.8 g/L vs.2.8±0.9 g/L,P<0.001),and base excess(BE,-4.9±4.6 mmol/L vs.-1.2±3.1 mmol/L,P<0.001)were significantly lower in the TIC group than in the non-TIC group.Multivariate logistic regression analysis revealed that ISS>16(OR:3.404,95%CI:1.471-7.880;P=0.004),SI>1(OR:5.641,95%CI:1.700-18.719;P=0.005),low BE(OR:0.868,95%CI:0.760-0.991;P=0.037),hypocalcemia(OR:0.060,95%CI:0.009-0.392;P=0.003),and hypofibrinogenemia(OR:0.266,95%CI:0.168-0.419;P<0.001)were independent risk factors for TIC in elderly trauma patients.The AUC of the prediction model included all these risk factors was 0.887(95%CI:0.851-0.923)with a sensitivity and specificity of 83.6%and 82.6%,respectively. CONCLUSION:Higher ISS(more than 16),higher SI(more than 1),acidosis,hypocalcemia,and hypofibrinogenemia emerged as independent risk factors for TIC in elderly trauma patients.
