ABSTRACT

ObjectiveTo investigate the clinical efficacy of Qihuang Jianpi Zishen Granules in the treatment of systemic lupus erythematosus (SLE) and its effect on the signal transducer and activator of tranSCription 3/mammalian target of rapamycin (STAT3/mTOR) signaling pathway, and to decipher the possible mechanism. MethodSixty female SLE patients who met the criteria in the First Affiliated Hospital of Anhui University of Chinese Medicine from May 2022 to May 2023 were selected and randomized into a control group and an observation group (30 cases in each group). The control group was treated with prednisone acetate + hydroxychloroquine sulfate orally, and the observation group was additionally treated with Qihuang Jianpi Zishen granules. The treatment lasted for 8 weeks. The SLE disease activity (SLEDAI), TCM syndrome score, erythrocyte sedimentation rate (ESR), hypersensitive C-reactive protein (hs-CRP), immune indexes [immunoglobulin G (IgG), C3, C4, CD4+, and CD8+], interleukin (IL)-17, IL-23, interferon (IFN)-γ, 24 h urinary protein (24 h PRO), serum creatinine (SCr), and expression of proteins [STAT3, phosphorylated (p)-STAT3, mTOR protein and STAT3,mTOR mRNA] in the STAT3/mTOR signaling pathway were determined before and after treatment. In addition, the adverse reactions were recorded. ResultAfter 8 weeks of treatment, the total response rate in the observation group was 93.33% (28/30), which was higher than that (70.00%, 21/30) in the control group (χ2=4.007, P<0.05). After treatment, both groups showed declined SLEDAI, TCM syndrome score, ESR, hs-CRP, IgG, CD8+, IL-17, IL-23, IFN-γ, 24 h PRO, SCr, and expression of proteins in the STAT3/mTOR pathway (P<0.01) and elevated levels of C3, C4, and CD4+ (P<0.01). Moreover, the observation group had lower SLEDAI, TCM syndrome score, ESR, hs-CRP, IgG, CD8+, IL-17, IL-23, IFN-γ, 24 h PRO, SCr, and expression of proteins in the STAT3/mTOR pathway (P<0.05, P<0.01) and higher levels of C3, C4, and CD4+ (P<0.05, P<0.01) than the control group after treatment. Neither group showed serious adverse reactions during the treatment period. ConclusionQihuang Jianpi Zishen Granules can ameliorate the inflammatory response, reduce the disease activity, and mitigate the kidney injury in SLE by inhibiting the STAT3/mTOR signaling pathway to regulate the immune function.

ABSTRACT

OBJECTIVE@#To observe the alteration of thoracic and lumbar physiological curvature in adolescent idiopathic scoliosis(AIS) and the difference of physiological curvature between different types of scoliosis.@*METHODS@#A retrospective analysis was conducted on 305 adolescent patients taken full spine X-ray in our hospital from January 2017 to December 2021. The patients were divided into normal group and scoliosis group. The normal group was composed of 179 patients, 79 males and 100 females, aged 10 to 18 years old with an average of (12.84±2.10) years old, with cobb agle less than 10 degrees. The scoliosis group was composed of 126 patients, 33 males and 93 females, aged 10 to 18 years old with an average of (13.92±2.20) years old. The gender, age, Risser sign, thoracic kyphosis(TK) and lumbar lordosis(LL) in 2 groups were compared, and the TK and LL were also compared between different genders, different degrees of scoliosis and different segments of scoliosis.@*RESULTS@#The female ratio(P=0.001) and age (P<0.001) in scoliosis group were higher than them in normal group; the ratio of low-grade ossification was higher in normal group than in scoliosis group(P=0.038). TK was significantly smaller in scoliosis group than in normal group(P<0.001), but there was no significant difference in LL between the 2 groups(P=0.147). There were no significant difference in TK and LL between male and female. The TK was significantly bigger in mild AIS patients than in moderate AIS patients(P<0.05), but there was no significant difference in LL between mild and moderate patients(P>0.05). The TK and LL in different segments scoliosis were not found significant difference.@*CONCLUSION@#The physiological curvature of thoracic and lumbar spine is independent of gender. The thoracic physiological curvature becomes smaller in AIS patients, but lumbar curvature remains unchanged. The thoracic physiological curvature in mild AIS patients is greater than that in moderate AIS patients, but the lumbar curvature is almost unchanged between mild and moderate scoliosis and is similar with that in normal adolescent. The alteration of thoracic and lumbar physiological curvature in AIS patients may be related to relative anterior spinal overgrowth, and the specific detailed mechanism needs to be further studied.

ABSTRACT

ObjectiveTo investigate the clinical efficacy and safety of Qihuang Jianpi Zishen granules in the treatment of cardiac involvement in systemic lupus erythematosus (SLE). MethodA total of 62 SLE patients with cardiac involvement treated in the Department of Rheumatology and Immunology, the First Affiliated Hospital of Anhui University of Chinese Medicine from June 2021 to December 2022 were randomized into control and observation groups (n=31). The control group was treated with methylprednisolone tablets and hydroxychloroquine sulfate tablets, and the observation group with Qihuang Jianpi Zishen granules on the basis of the therapy in the control group. After 12 weeks of treatment, the two groups were compared in terms of the therapeutic effect, cardiac function indicators [left atrial end-diastolic diameter (LADd), left ventricular end-diastolic diameter (LVDd), left ventricular posterior wall thickness (LVPWTd), peak blood flow velocity in early diastolic period (peak E), peak blood flow velocity in late diastolic period (peak A), E/A ratio, stroke volume (SV), left ventricular ejection fraction (LVEF), left ventricular short axis shortening rate (LVFS), and B-type natriuretic peptide (BNP)], vascular damage indicators [nitric oxide (NO), endothelin-1 (ET-1), vascular endothelial growth factor (VEGF), and homocysteine (Hcy)], inflammation indicators [erythrocyte sedimentation rate (ESR) and hypersensitive C-reactive protein (Hs-CRP)], anti-double-stranded DNA (dsDNA) antibodies, disease activity index (SLEDAI) score, mitigation of symptoms and signs, and occurrence of adverse reactions. ResultThe total response rate in the observation group was 87.09%, which was higher than that (67.74%) in the control group (P<0.01), and the incidence of adverse reactions had no significant difference between the two groups. After treatment, the control group showed lowered LVDd, LVPWTd, BNP, ET-1, VEGF, and Hcy (P<0.05) and increased E peak, E/A ratio, SV, LVEF, and LVFS (P<0.05). In the observation group, LADd, LVDd, LVPWTd, peak A, BNP, NO, ET-1, VEGF, and Hcy decreased (P<0.05), while peak E, E/A ratio, SV, LVEF and LVFS increased (P<0.05) after treatment. The treatment in both groups decreased the scores of palpitation, chest tightness, dyspnea, and edema (P<0.05), reduced ESR, Hs-CRP, ds-DNA, and SLEDAI (P<0.05). After treatment, the observation group had lower LADd, LVDd, LVPWTd, peak A, BNP, and scores of palpation, chest tightness, dyspnea, and edema (P<0.05) and higher peak E, E/A ratio, SV, LVEF, and LVFS (P<0.05) than the control group. In addition, the observation group had lower NO, ET-1, VEGF, Hcy, ESR, Hs-CRP, ds-DNA, and SLEDAI than the control group (P<0.05). ConclusionQihuang Jianpi Zishen granules combined with hydroxychloroquine sulfate and methylprednisolone can improve multiple indicators and mitigate the symptoms and signs of SLE patients with cardiac involvement, demonstrating a clinical application value.

ABSTRACT

Objective:To investigate the risk factors affecting in-hospital mortality in patients with acute mesenteric ischemia (AMI).Methods:From January 1, 2014 to June 30, 2022, the clinical data of 67 patients diagnosed with AMI at Renmin Hospital of Wuhan University were retrospectively analyzed, which included basic data (age, gender, past medical history and comorbidities, etc.), laboratory results (white blood cell count (WBC), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, prothrombin time (PT), etc.), and imaging manifestations (intestinal pneumatosis, intestinal wall thickening, intestinal dilation, ascites). The clinical data of AMI patients who died during hospitalization were compared with that of AMI patients who survived. Binary logistic regression was used to analyze the independent risk factors of in-hospital mortality in patients with AMI. Mann-Whitney U test and chi-square test were used for statistical analysis. Results:Among the 67 patients with AMI, 17 died and 50 survived. There were significant differences between died and survived patients with AMI in age, the proportion of patients with organ failure, WBC, ALT, AST, creatinine, PT, and the proportion of patients with intestinal dilatation and ascites (76 years old(68 years old, 79 years old) vs. 61 years old (50 years old, 74 years old), 12/17 vs.12.0%(6/50), 15.8×10 9/L(13.5×10 9/L, 23.7×10 9/L) vs. 12.1×10 9/L (9.1×10 9/L, 19.4×10 9/L), 32.0 U/L(19.0 U/L, 88.5 U/L) vs. 20.5 U/L(14.8 U/L, 29.0 U/L), 64.0 U/L(33.8 U/L, 117.0 U/L) vs. 26.0 U/L (18.5 U/L, 36.8 U/L), 135.0 μmol/L(61.5 μmol/L, 198.5 μmol/L) vs. 73.5 μmol/L(60.5 μmol/L, 85.0 μmol/L), 13.7 s(12.9 s, 16.3 s) vs. 12.7 s (11.9 s, 13.6 s), 13/17 vs. 38.0%(19/50), 10/17 vs. 24.0% (12/50); Z=3.06, χ2=22.16, Z=2.01, 2.69, 4.08, 2.45 and 2.78, χ2=7.53 and 6.98; P=0.002, <0.001, =0.044, =0.007, <0.001, =0.014, =0.006, =0.006 and =0.008). The results of binary logistic regression analysis showed that age ( OR=1.224, 95% confidence interval 1.011 to 1.482, P=0.038), organ failure ( OR=113.989, 95% confidence interval 1.353 to 9 604.644, P=0.036), and ascites ( OR=348.289, 95% confidence interval 1.676 to 72 357.934, P=0.032) were independent risk factors of in-hospital mortality in AMI patients. Conclusion:Age, organ failure and ascites are independent risk factors of in-hospital mortality in AMI patients.

ABSTRACT

Objective:To observe the clinical efficacy of combining electroacupuncture with long needle sacral nerve acupuncture in the treatment of diabetic overactive bladder.Methods:A total of 90 patients with diabetic overactive bladder were randomly divided into an observation group and a control group, each of 45. In addition to the basic treatment for diabetes, the observation group received electroacupuncture combined with long needle sacral nerve acupuncture 5 times a week for 4 weeks, while the control group was given 5mg of oral solinax succinate once a day as a course of treatment. One week before the beginning of the experiment and one week before its end, urination diary cards were used to record the average number of times of daytime and nighttime urination daily, as well as any urgent urination and urinary incontinence during the week. Bladder overactivity syndrome score (OABSS), the bladder overactivity quality of life questionnaire (OAB-q), maximum urine flow rate (Qmax) and mean urine flow rate (Qave) were employed to quantify urination status, life quality and the urodynamics of the 2 groups before and after the treatment.Results:After the treatment, significant improvement was observed in the average weekly incidence of daytime and nighttime urination, of urgent urination and of urinary incontinence. The average OABSS, OAB-q, Qmax and Qave scores improved in both groups, but the experimental group showed significantly better improvement than the control group.Conclusion:Electroacupuncture combined with sacral nerve needling can significantly reduce the frequency of urination, relieve the symptoms of urgent urination and incontinence, and improve the rate of urine flow, improving the life quality of patients with diabetic overactive bladder.

ABSTRACT

Dermatomyositis, a common autoimmune disease in clinical practice, often involves muscles and lungs, and can be complicated by malignant tumors, and the lung involvement can be fatal. Therefore, early diagnosis and treatment of dermatomyositis is of great benefit for the reduction of muscle and lung injury, early recognition and management of malignant tumors, and improvement of prognosis and survival rate of patients. However, the heterogeneity and various clinical manifestations of dermatomyositis pose challenges to early diagnosis. This article describes risk factors for dermatomyositis complicated by rapidly progressive pulmonary interstitial fibrosis, dysphagia or malignant tumors, and proposes a mode of "rashes + nailfold capillary abnormalities + myositis antibodies" for the early diagnosis of dermatomyositis, early recognition of important visceral injury and tumors, and early management, in order to improve overall survival rate of patients.

ABSTRACT

Objective:To investigate the effect and mechanism of ionizing radiation on ferroptosis in mouse hepatocytes.Methods:Twenty-four C57BL/6J mice were divided into two groups by random number table method: healthy control group (control group, n=6) and irradiation group (whole liver was irradiated with a single dose of 30 Gy X-ray, n=18). Mice were sacrificed at 6, 24 and 72 h (6 mice per time point) after irradiation to obtain liver tissue and plasma samples. The contents of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in plasma were measured by automatic biochemical analyzer. The prothrombin time (PT) and activated partial thromboplastin time (APTT) were measured by automatic biochemical analyzer. Pathological changes of liver tissues were observed by hematoxylin-eosin (HE) staining. The iron deposition in liver tissues was detected by Prussian blue staining. The expression levels of 4-Hydroxynonenal (4HNE) and hepcidin in the liver were determined by immunohistochemical staining, and quantitative analysis was performed. Plasma malondialdehyde (MDA) content, superoxide dismutase (SOD) activity, total antioxidant capacity (T-AOC) and glutathione (GSH) content were determined by microplate reader analysis according to the kit instructions. The expression levels of transferrin receptor 1 (TfR1), p53, solute carrier family 7 member 11 (SLC7A11) and glutathione peroxidase 4 (GPX4) in the liver were measured by Western blot. Results:Compared with the control group, the plasma contents of ALT ( t=5.15, 5.47, both P<0.001) , AST at 6 and 24 h after irradiation were increased ( t=8.42, 2.50, both P<0.001), the plasma PT was prolonged ( t=3.12, P=0.011) and the APTT was shortened ( t=3.26, P=0.009) at 72 h after radiation in the irradiation group. Histopathological results showed that evident liver edema was observed at 6, 24 and 72 h after irradiation ( t=9.58, 10.09, 18.70, all P<0.001). Different degrees of iron deposition were observed ( t=8.57, 15.31, 32.11, all P<0.001). The infiltration of hepcidin positive cells was significantly increased after irradiation ( t=5.36, 13.17, 17.11, all P<0.001). The number of 4HNE positive cells was significantly increased ( t=18.86, 22.67, 9.12, all P<0.001). At the same time, ionizing radiation induced a significant increase in plasma MDA content ( t=4.36, 7.47, 8.22, all P<0.001), and a decrease in SOD ( t=4.52, 5.80, 7.60, all P<0.001), T-AOC ( t=13.24, 20.49, 24.96, all P<0.001) and GSH ( t=2.78, 6.07, 11.25, P=0.020, <0.001, <0.001), respectively. The expression level of TfR1 protein was significantly up-regulated ( t=3.46, 5.40, P=0.026, 0.006), whereas that of GPX4 protein was significantly down-regulated ( t=11.88, 30.63, both P<0.001) at 24 and 72 h after irradiation. At 6, 24 and 72 h after irradiation, the expression level of p53 protein was significantly up-regulated and maintained at a high level ( t=7.84, 4.25, 8.22, P=0.001, 0.013, 0.001), while that of SLC7A11 protein was significantly down-regulated ( t=9.29, 19.96, 9.09, all P<0.001). Conclusion:Ionizing radiation induces the ferroptosis in hepatocytes, and its mechanism may be related to the activation of p53-SLC7A11-GPX4 pathway.

ABSTRACT

Objective:To analyze the clinical characteristics of infantile Takayasu Arteritis (TAK) complicated with cardiac involvements.Methods:The clinical data and cardiac lesions of infantile TAK were collected retrospectively, and the clinical characteristics of the disease were analyzed and summarized. Mainly using decriptive statistical methods.Results:In these 20 cases, 16 cases (80%) had cardiac involvements, only 2 cases had related symptoms. The common lesions were coronary artery lesion (CAL), valvular disease, and elevated myocardial enzymes, while the rare lesions were arrhythmia, pericardial effusion, hypertensive heart disease, and heart failure. One case had acute heart failure, which was systolic heart failure and was accompanied by hypertensive heart disease. All 14 patients with CAL were found by conventional coronary ultrasound screening. A total of 39 CAL were found, all of which were coronary artery dilation, and the left main coronary artery was involved. Five patients had heart valve disease, all of them were valve insufficiency. The involved valves were mitral and tricuspid valves, and one of them was severe insufficiency. Arrhythmias were found in 2 cases, of which P1 was found to have paroxysmal atrial tachycardia with high atrioventricular block at 3 months. All 20 children survived and were in stable condition after being treat with biological agents and/or glucocorticoids. A case of hypertensive heart disease complicated with heart failure was followed up for 4 years, and the cardiac function and blood pressure returned to normal. Fourteen children with CAL lesions were given oral aspirin disease, the CALs disappeared in 10 cases and retracted in 4 cases. During the follow-up of 5 children with heart valves, insufficiency disappeared in 4 cases and improved in 1. No child underwent valve replacement during the follow-up. One of the children with arrhythmia was treated with antiarrhythmic drugs. After treatment, the arrhythmia disappeared. Now they have been followed up for 5 years without recurrence.Conclusion:Infantile TAK has a high incidence of heart involvement, with extensive lesions but insidious clinical symptoms. CALs are common, and heart failure is rare. It should be evaluated and treated as early as possible.

ABSTRACT

Objective:To compare the clinical efficacy between bone transport technique combined with bone grafting plus internal fixation and simple bone transport technique in the treatment of large segmental bone defects at lower limbs after trauma.Methods:A retrospective study was conducted to analyze the clinical data of 42 patients with large segmental bone defects at lower limbs after trauma who had been treated at Department of Trauma Orthopaedics, Honghui Hospital Affiliated to Medicine College, Xi'an Jiaotong University from September 2015 to September 2019. The patients were divided into 2 groups according to the different methods of repairing bone defects. In group A of 18 patients subjected to bone transport combined with bone grafting plus internal fixation, there were 11 males and 7 females with an age of (35.2±10.3) years, and 12 tibial defects and 6 femoral defects; in group B of 24 patients subjected to simple bone transport, there were 15 males and 9 females with an age of (37.3±9.4) years, and 17 tibial defects and 7 femoral defects. The external fixation time (EFT), external fixation index (EFI), total cure time and complications were recorded and compared between the 2 groups. At the last follow-up, the Ennecking score for limb functional recovery (score/total score 30) and Self-rating Anxiety Scale (SAS) were used to evaluate respectively the functional recovery of the limbs and postoperative anxiety.Results:The 2 groups were comparable because there was no significant difference between them in preoperative general data or follow-up time ( P>0.05). There was no statistically significant difference in the number of surgeries between the 2 groups ( P>0.05). The EFT [(5.9±1.5) months], EFI [(0.45±0.09) months/cm], total treatment time [(16.2±2.4) months], Ennecking score for limb functional recovery (87.0%±8.6%), SAS score [(43.2±9.0) points], and complications per capita [(0.4±0.2) times/case] in group A were significantly better than those in group B [(15.3±4.2) months, (1.19±0.28) months/cm, (19.7±3.5) months, (77.3%±9.2%), (58.2±9.3) points, and (1.2±0.5) times/case] (all P<0.05). Conclusion:In the treatment of large segmental bone defects at lower limbs, compared with simple bone transport technique, bone transport technique combined with bone grafting plus internal fixation has advantages of shorter external fixation time and overall cure time, a lower rate of complications, and better functional recovery of the limbs.

Objective:To investigate the clinical effects of antibiotic-loaded calcium sulfate-autologous iliac bone combined with sural neurocutaneous flap in the one-stage treatment of chronic calcaneus osteomyelitis plus skin and soft tissue defects.Methods:From January 2013 to September 2019, 48 patients were admitted to Department of Orthopedic Trauma, Xi'an Honghui Hospital Affiliated to Xi'an Jiaotong University for chronic calcaneal osteomyelitis complicated with skin and soft tissue defects. They were divided into 2 groups according to different bone grafts. In group A of 26 patients treated at one stage by antibiotic-loaded calcium sulfate-autologous iliac bone combined with sural neurocutaneous flap, there were 16 males and 10 females with an age of (45.0±11.7) years and an area of skin defect of (56.0±16.7) cm 2. In group B of 22 patients treated at one stage by simple autologous iliac bone combined with sural neurocutaneous flap, there were 13 males and 9 females with an age of (43.6±9.6) years and an area of skin defect of (53.8±16.2) cm 2. The volume of the ilium harvested, fracture healing time, infection control, donor site complications, pain score of visual analogue scale (VAS) and function recovery of the ankle were compared between the 2 groups. Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). The 48 patients were followed up for (15.3±6.0) months. Group A had a significantly smaller volume of the ilium harvested [(67.3±14.1) cm 3] than group B [(90.7±23.5) cm 3], a significantly lower rate of donor site complications [3.8% (1/26)] than group B [31.8% (7/22)], significantly lower VAS pain scores at 6, 12, 24, 48 and 72 hours than group B, and significantly lower WBC count, erythrocyte sedimentation rate and C-reactive protein at 2, 4, 8 weeks after operation than group B (all P<0.05). There was no statistically significant difference between the 2 groups in the infection control rate [96.2% (25/26) versus 77.3% (17/22)], the fracture healing time [(6.2±1.9) months versus (6.4±2.1) months], or the ankle-hindfoot score of AOFAS (The American Orthopaedic Foot and Ankle Society) (83.9±7.2 versus 82.5±8.7) at 6 months after operation (all P>0.05). Conclusion:In one-stage treatment of chronic calcaneal osteomyelitis complicated with skin and soft tissue defects, compared with simple autologous iliac bone combined with sural neurocutaneous flap, antibiotic-loaded calcium sulfate-autologous iliac bone combined with sural neurocutaneous flap can reduce the volume of the ilium harvested, pain score of VAS, and incidence of donor site complications, and improve the recovery of inflammatory indicators, leading to fine clinical effects.

ABSTRACT

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

ABSTRACT

Objective:To study the effect of iodine excess on antioxidant capacity and blood lipid in adult.Methods:A survey was conducted in areas with different iodine nutrition levels in Shandong and Shanxi provinces to collect fasting morning urine and venous blood samples of adults. Urinary iodine, serum levels of superoxide dismutase(SOD), malondialdehyde (MDA), total cholesterol (TCHO), triglyceride (TG), apolipoprotein A1 (apoA1) and apolipoprotein B (apoB), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were determined. According to the median urinary iodine of the population in the investigated village, they were divided into appropriate iodine group (100-299 μg/L) and iodine excess group (≥300 μg/L) . Multiple linear regression was used to analyze the effects of iodine nutrition and other factors on oxidative stress indexes and blood lipids. Partial correlation analysis was used to analyze the relationship between iodine nutrition and oxidative stress indexes and blood lipids.Results:A total of 1 049 subjects were included, including 471 in the appropriate iodine group and 578 in the iodine excess group. The median (quartile) urinary iodine of the appropriate iodine group and the iodine excess group was 228.70 (157.02, 341.49) and 558.73 (298.06, 985.06) μg/L, respectively. The serum SOD level of the appropriate iodine group and the iodine excess group was 12.60 (10.83, 14.10) and 11.29 (9.18, 13.10) U/ml, respectively, and the difference between the groups was statistically significant ( U = 92 697.50, P < 0.001). There were statistically significant differences in serum TG, HDL-C and apoB levels between the appropriate iodine group and the iodine excess group ( U = 108 879.50, 96 613.50, 99 050.50, P < 0.05). The results of multiple linear regression showed that after excluding age, gender and body mass index (BMI), there was a negative correlation between iodine nutrition and serum SOD and HDL-C levels [standard regression coefficient ( β) = - 0.196, - 0.294, P < 0.001]. Partial correlation analysis showed that there was a negative correlation between iodine nutrition and serum SOD and HDL-C levels [correlation coefficient ( r) = - 0.16, - 0.09, P < 0.05]. Conclusion:Excessive iodine intake affects oxidative stress and lipid metabolism in human body.

ABSTRACT

Objective:To investigate the effect of T-lymphocyte and subpopulation counts on the prognosis of severe acute pancreatitis (SAP) patients.Methods:The clinical data of 90 patients with SAP diagnosed at the Shanghai General Hospital between January 2019 and June 2022 were retrospectively analyzed, and the patients were divided into good prognosis and poor prognosis group according to whether they were diagnosed for 28 d. The general information of the patients was recorded, including blood-related immunological indicators within 24 h of diagnosis, including leukocytes, neutrophils, lymphocytes, monocytes, CD 3+ , CD 4+ , CD 8+ T-lymphocyte count and CD 4+ /CD 8+ T-lymphocyte ratio, IgG4 level; blood inflammation index procalcitonin, albumin level and APACHEⅡ score at admission; survival and complication status of patients at 28 d of diagnosis. Non-parametric Mann-Whitney U test was used to analyze the correlation between each index and the prognosis of the patients. The subject operating characteristic curve (ROC) of patients was plotted, and area under curve (AUC) was calculated to assess the value of CD 3+ and CD 4+ T-lymphocytes in predicting the prognosis of SAP. Results:The majority of SAP patients were male (65.6%). The main cause of SAP was gallstone (56.7%), followed by hyperlipidemia (35.6%). At 28 days after diagnosis, 85(94.4%) patients survived, and 39 of them were cured and included in the good prognosis group. Forty-six cases were complicated with infection, multiple organ dysfunction syndrome (MODS) and local pancreatic complications, and 5 cases (5.56%) died; and a total of 51 cases were included in the poor prognosis group. Compared with the good prognosis group, the number of CD 3+ T-lymphocytes [366(268, 498) cells /μl vs 709(578, 999) cells /μl], CD 4+ T-lymphocytes [209(120, 298) cells /μl vs 486(303, 548) cells /μl] and albumin level (33.9 g/L vs 35.9 g/L) within 24 hours in the poor prognosis group were significantly lower, while the level of procalcitonin (1.02 ng/ml vs 0.43 ng/ml) and APACHEⅡ score [7(4, 10) vs 5(3, 8)] were significantly increased, and all the differences were statistically significant (all P value <0.05). ROC curve analysis showed that the AUC values for CD 3+ and CD 4+ T-lymphocyte counts within 24 hours for predicting poor prognosis of SAP were 0.857 (95% CI 0.696-1.000) and 0.867 (95% CI 0.708-1.000), respectively. The cut-off values were 524 cells /μl and 301 cells /μl, the sensitivity were both 85.7%, and the specificity were 78.6% and 85.7%, respectively. Conclusions:The significant decrease of peripheral blood CD 3+ and CD 4+ T-lymphocyte count within 24 h of SAP diagnosis has a certain predictive value for the prognosis of patients with SAP.

ABSTRACT

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.

ABSTRACT

Objective:To analyze the therapeutic effect of sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft of chronic calcaneal osteomyelitis.Methods:A retrospective analysis was peformed in 29 patients with chronic calcaneal osteomyelitis treated with sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft in the Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from April 2013 to January 2020. There were 19 males and 10 females, with the age of (45.38±12.85) years, ranged from 22 to 67 years. The course of disease was (16.00±6.96) months, ranged from 6 to 36 months. The skin defect area was (41.9±15.9) cm 2, ranged from 11.8 to 86.8 cm 2. The causes of injury: 18 cases of high fall, 6 cases of traffic accidents, 3 cases of heavy rolling, the remaining 2 cases were machine strangulation and sharp stab wounds. The inflammatory markers [white blood cell (WBC), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), C reactive protein (CRP)] and bone healing time were recorded before operation, 2, 4, 8 weeks and 6 months after operation. During the follow-up period, the flap texture, survival were observed, and the ankle-posterior foot function recovery was evaluated by the American Association of Foot and Ankle Surgery (AOFAS) score were observed before and after the operation, and the incidence of complications were recorded. The measurement data were expressed as mean±standard deviation ( ± s), and the t-test was used for inter-group comparison; the levels of WBC, ESR, PCT and CRP at different time points before and after operation were compared by repeated measurement ANOVA, and the LSD t-test was used for pairwise comparison. Results:All the 29 patients were followed up for (14.51±6.10) months, ranged from 6 to 30 months. All the flaps survived without abrasion, ulceration, or skin protrusion, and all patients could walk normally with shoes. There were 28 cases of stage I bone healing, with an average of (5.87±2.07) months, ranged from 3 to 12 months. The inflammatory indexes was significantly decreased at different time points after operation ( P<0.05). There was no significant difference between 6 months and 8 weeks after operation ( P>0.05), while there was significant difference at other time points ( P<0.05). The ankle-posterior foot score of AOFAS at 6 months after treatment was significantly higher than that before treatment (83.44±7.93 vs 55.37±8.07), the differences was statistically significant ( P<0.05). The clinical efficacy of foot function recovery was excellent in 12 cases, good in 15 cases and fair in 2 cases among 29 patients .The excellent and good rate was 93.1% (27/29). One patient recurred 1 month after operation and was re-implanted with antibiotic-loaded calcium sulfate mixed autogenous iliac bone after debridement, no recurrence was found. The total complication rate was 31.0%, but there was no significant impact on the patient's life in the later period. All patients returned to daily life and work. Conclusion:The treatment of chronic calcaneal osteomyelitis with sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft can effectively control infection, reconstruct calcaneal and soft tissue structure, promote functional recovery of affected limb, and ultimately improve the patient′s quality of life.

ABSTRACT

Objective:To compare the clinical effects of acute shortening-lengthening technique with antibiotic calcium sulfate-loaded bone transport technique for the treatment of segmental tibial defects after trauma.Methods:The clinical data of 58 patients with large tibial defects treated by Ilizarov technique in Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from May 2014 to December 2019 were retrospectively analyzed. Thirty patients were treated by acute shortening-lengthening (group A), and they were divided into those who were successful in one-time shortening during operation (group A1) and those who needed gradual shortening after operation (group A2) according to different shortening conditions. And 28 patients by antibiotic calcium sulfate-loaded bone transport (group B). The external fixation time (EFT) and external fixation index (EFI) of the two groups were compared. Bone defect healing and limb functions were evaluated according to the Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria. Complications were compared by Paley classification. The measurement data of normal distribution were expressed as ± s, and t-test was used for comparison between groups; the count data were expressed as n(%), and the chi-square test, Fisher exact probability method or Mann-Whitney U test were used for comparison between groups. Results:Patients were followed for(27.5±5.1)months. There was no significant difference in EFT, EFI, bone defect healing and limb functions between the two groups( P>0.05). The incidence of Grade-Ⅱ[41.2% (7/17)], Grade-Ⅲ [47.1% (8/17)] pin-tract infection in group A1 and Grade-Ⅱ[46.2% (6/13)], Grade-Ⅲ pin-tract [53.8% (7/13)] in group A2 was significantly higher than those in group B[14.3% (4/28)], [17.9% (5/28)] ( P<0.05). The number of complications per capita in group A1 [(1.4±0.3) times/case] and in group A2 [(1.5±0.3) times/case]was significantly higher than that in group B [(1.1±0.5) times/case]. Conclusions:Patients can be cured successfully by both acute shortening-lengthening and bone transport techniques. Compared with acute shortening-lengthening group, the complication incidence in antibiotic calcium sulfate-loaded bone transport group was lower, especially, the infection-related complications. Therefore, antibiotic calcium sulfate-loaded bone transport technique has a greater application prospect in patients with large segmental bone defects caused by infection or osteomyelitis.

ABSTRACT

Objective:To prepare chitosan/gelatin hydrogel composite hemostatic materials loaded with Panax notoginseng (PN/CMC/GMs) and evaluate their performance. Methods:PN/CMC/GMs hydrogel composite hemostatic material were prepared by the freeze-drying method, and their morphology was observed by scanning electron microscopy. Their rheological properties were observed by a rheometer. Their water absorption rate was tested by dissolution. Their biocompatibility was detected by a cytotoxicity assay. Their rapid hemostatic effect was tested using a SD rat liver hemorrhage model.Results:PN/CMC/GMs composite hemostatic materials were prepared in a lattice-like structure with certain porosity. With the increase in Panax notoginseng powder content, the modulus of PN/CMC/GMs increased accordingly, and the mechanical strength increased. PN/CMC/GMs have better water absorption and expansion functions, which can form compression hemostasis and concentrated blood to achieve rapid hemostasis, and have good biocompatibility. Hemostasis experiments showed that the hemostatic time and hemostatic effect of PN, CMC/GMs hemostatic materials on liver injury in rats were better than those of the blank control group. Conclusions:PN/CMC/GMs have good hemostatic effect and biocompatibility and have the potential for further research and clinical application.
