ABSTRACT

Background The number of persons with thyroid nodules has increased rapidly in recent years, and thyroid cancer caused by malignant nodules has become a key problem endangering the health of young and middle-aged groups in China. Objective To explore work and lifestyle influencing factors for developing thyroid cancer among young and middle-aged patients with thyroid nodules. Methods The subjects with thyroid nodules were reported by routine physical examines ordered at the Huadong Sanatorium. We conducted a 1∶4 matched case-control study in which 232 patients diagnosed with thyroid cancer from 2012 to 2022 were matched to 928 controls by gender and age (±5 years). A validated questionnaire was used to collect data on work and lifestyle behaviors. Univariate and multivariate logistic regression models were applied to explore potential relationships between selected factors (including environment, working hours, stress, diet, exercise, and mental health) and thyroid cancer. Spearman rank correlation was used to analyze the correlations between variables. Results The results of univariate logistic regression showed a history of thyroid cancer reported among first-degree relatives (OR=6.059, 95%CI: 1.007, 36.473), obesity (OR=1.973, 95%CI: 1.296, 3.004), noise and vibration exposure (OR=1.988, 95%CI: 1.143, 3.456), frequent stress (OR=2.093, 95%CI: 1.231, 3.559), frequent depression (OR=2.034, 95%CI: 1.048, 3.947), frequent anger (OR=1.791, 95%CI: 1.066, 3.012), frequent fried food diet (OR=1.535, 95%CI: 1.026, 2.297), and frequent fast food diet (OR=1.836, 95%CI: 1.048, 3.215) were risk factors for reporting thyroid cancer developing from thyroid nodules, while regular meals (OR=0.245, 95%CI: 0.061, 0.989) and frequent exercise (OR=0.571, 95%CI: 0.342, 0.952) were protective factors for reporting no thyroid cancer. The results of Spearman correlation analysis showed that body mass index was positively correlated with frequent fried food, fast food, and sugary beverage diets (r=0.123, 0.083, 0.077, P<0.01), and negatively correlated with frequent depression and anger (r=−0.090, −0.070, P<0.05). The results of multiple logistic regression found that a history of thyroid cancer reported among first-degree relatives (OR=6.712, 95%CI: 1.071, 42.066), obesity (OR=2.032, 95%CI: 1.321, 3.125), noise and vibration exposure (OR=1.991, 95%CI: 1.089, 3.637), and frequent stress (OR=2.468, 95%CI: 1.417, 4.300) were associated with an elevated risk of reporting thyroid cancer developing from thyroid nodules patients. Regular exercise (frequency≥3 times·week−1, > 30 min per episode) (OR=0.516, 95%CI: 0.300, 0.890) was associated with a lowered risk of reporting thyroid cancer. Conclusions Multiple risk factors associated with reporting thyroid cancer among young and middle-aged groups with thyroid nodules are identified, such as obesity, noise and vibration exposure, frequent stress, and lack of exercise.

ABSTRACT

Coronary microvascular dysfunction (CMD) is one of the important causes of myocardial ischemia and non-obstructive coronary artery ischemic symptoms. However, effective diagnostic methods and targeted treatment strategies for CMD are currently lacking. According to traditional Chinese medicine (TCM), the comorbidity theory of "blood-vessel-cardiac collaterals" plays a central role throughout the entire development process of CMD. It suggests that in the clinical diagnosis and treatment of CMD, the treatment of blood, vessels, and cardiac collaterals should not be neglected. In light of this, insect medicines, known for their efficacy in promoting blood circulation, resolving stasis, and alleviating spasms, hold promise as a potential treatment for CMD. However, there is currently no research or summary on the use of insect medicines for the treatment of CMD. Therefore, this article took the comorbidity theory of "blood-vessel-cardiac collaterals" as the starting point and divided the pathogenesis of CMD into five evolution stages: Beginning in the blood (changes in blood components and hemorheology), progressing in the vessels (atheromatous plaque formation and unstable plaques), occurring in the cardiac collaterals (microvascular endothelial damage and microvascular constriction and spasms), ending in the cardiac collaterals (microvascular remodeling), and resulting in energy metabolism disorders throughout the process, so as to explore the pathogenesis and evolution of CMD. In addition, based on the modern pharmacological research on insect medicines, this article discussed the clinical application of insect medicines in the treatment of CMD from four aspects: Promoting blood circulation and removing blood stasis to relieve vessels' obstruction, relieving spasms to alleviate pain, combating poison with poison to disperse stagnation, and tonifying cardiac collaterals to nourish the heart, which aims to provide a theoretical basis for the use of TCM in treating CMD, broaden the scope of medication, and improve clinical efficacy.

ABSTRACT

A growing body of evidence has linked the gut microbiota to liver metabolism. The manipulation of intestinal microflora has been considered as a promising avenue to promote liver health. However, the effects of Lactobacillus gasseri LA39, a potential probiotic, on liver metabolism remain unclear. Accumulating studies have investigated the proteomic profile for mining the host biological events affected by microbes, and used the germ-free (GF) mouse model to evaluate host-microbe interaction. Here, we explored the effects of L. gasseri LA39 gavage on the protein expression profiles of the liver of GF mice. Our results showed that a total of 128 proteins were upregulated, whereas a total of 123 proteins were downregulated by treatment with L. gasseri LA39. Further bioinformatics analyses suggested that the primary bile acid (BA) biosynthesis pathway in the liver was activated by L. gasseri LA39. Three differentially expressed proteins (cytochrome P450 family 27 subfamily A member 1 (CYP27A1), cytochrome P450 family 7 subfamily B member 1 (CYP7B1), and cytochrome P450 family 8 subfamily B member 1 (CYP8B1)) involved in the primary BA biosynthesis pathway were further validated by western blot assay. In addition, targeted metabolomic analyses demonstrated that serum and fecal β‍-muricholic acid (a primary BA), dehydrolithocholic acid (a secondary BA), and glycolithocholic acid-3-sulfate (a secondary BA) were significantly increased by L. gasseri LA39. Thus, our data revealed that L. gasseri LA39 activates the hepatic primary BA biosynthesis and promotes the intestinal secondary BA biotransformation. Based on these findings, we suggest that L. gasseri LA39 confers an important function in the gut‒liver axis through regulating BA metabolism.

ABSTRACT

Objective:To investigate the clinical efficacy of percutaneous kyphoplasty (PKP) through the transverse process-pedicle approach (TPPA) by comparing with PKP through the conventional transpedicle approach (CTA).Methods:A retrospective study was conducted to analyze the data of 101 patients with single-segment osteoporotic vertebral compression fracture (OVCF) who had been treated at Department of Spine Surgery, The Fourth Hospital of Wuhan from August 2020 to August 2021. There were 31 males and 70 females, with an age of (70.3±7.6) years. Their T values of bone mineral density averaged (-3.0±0.3). They were divided into a TPPA group of 52 cases in which PKP was performed through the TPPA and a CTA group of 49 cases in which PKP was performed through the CTA. The clinical efficacy was evaluated by comparing the 2 groups in terms of operation time, frequency of intraoperative fluoroscopy, excellent to good rate of bone cement distribution, rate of bone cement leakage, refractures, and visual analogue scale (VAS), Oswestry disability index (ODI) and Beck index at preoperation, 24 hours, 3 months and 6 months postoperation.Results:There was no significant difference in the preoperative general data between the 2 groups, showing they were comparable ( P>0.05). All the patients were followed up for (9.8±1.5) months. Operations were completed successfully in all patients with no complications like nerve injury or pedicle fracture. There were no significant differences in operation time, frequency of intraoperative fluoroscopy or rate of bone cement leakage between the 2 groups ( P>0.05). In the TPPA group, the excellent to good rate of bone cement distribution [92.3% (48/52)] was significantly higher than that in the CTA group [61.2% (30/49)], the VAS score [3.0 (2.0, 4.0)] and ODI (57.2±4.6) at 24 hours postoperation were significantly lower than those in the CTA group [4.0 (3.0, 4.0) and 59.2±5.3] ( P<0.05). There were no significant differences in VAS or ODI between the 2 groups at preoperation, 3 months or 6 months postoperation ( P>0.05). The VAS and ODI improved steadily within each group, showing significant differences between every 2 time points ( P<0.05). The Beck indexes [0.81 (0.69, 0.86) and 0.76 (0.67, 0.81)] at 24 hours and 6 months postoperation in the TPPA group were significantly higher than those in the CTA group [0.75 (0.71, 0.79) and 0.72 (0.68, 0.77)] ( P<0.05). The Beck indexes at 24 hours and 6 months postoperation improved significantly in all patients compared with the preoperative values ( P<0.05). Conclusions:In the treatment of OVCF with PKP, the TPPA shows the same surgical safety as CTA does, but leads to better cement distribution, better pain relief at immediate postoperation and an advantage in restoring and maintaining the height of the injured vertebral body.

ABSTRACT

Objective:To compare the effect of reduction and internal fixation of composite acetabular fracture with the modified two-window iliofemoral approach and ilioinguinal approach.Methods:A retrospective cohort study was used to analyze the clinical data of 160 patients with composite acetabular fracture admitted to First Affiliated Hospital of Nanjing Medical University from January 2016 to August 2021, including 117 males and 43 females, aged 15-78 years [(44.1±16.0)years]. According to the Letournel classification system, there were 101 patients with both-column fracture, 5 with anterior wall/column combined with posterior semi-transverse fracture and 24 with T-shaped fracture. A total of 80 patients were treated using the modified iliofemoral incision combined with limited Pfannstiel incision (modified two-window iliofemoral approach group) and the other 80 patients were treated using the ilioinguinal approach (ilioinguinal approach group). The fracture healing was observed. The operation time and intraoperative bleeding volume were compared between the two groups. The quality of fracture reduction was evaluated by Matta scoring standard at 1 day and 6 months after operation. The modified Merle d′Aubigne & Postel scoring standard was used to evaluate the function of the affected hip joint at the last follow-up. The incidence of complications such as neurovascular injury, iatrogenic bladder injury, heterotopic ossification and femoral head necrosis were compared between the two groups.Results:All patients were followed up for 12-78 months [(43.3±17.9)months], with bony union of the fracture. The operation time and intraoperative bleeding volume in modified two-window iliofemoral approach group were 150.0 (123.8, 180.0)minutes and 600.0 (500.0, 787.5)ml when compared to 190.0 (150.0, 240.0)minutes and 700.0 (562.5, 887.5)ml in ilioinguinal approach group (all P<0.01). There was no significant difference between the two groups in the quality of fracture reduction at 1 day and 6 months after operation, function of hip joint at the last follow-up and incidence of complications (all P>0.05). Conclusions:For reduction and internal fixation of composite acetabular fracture, the modified two-window iliofemoral approach has advantages over the ilioinguinal approach in reducing operation time and intraoperative bleeding, although both methods yield similar results in fracture reduction quality, postoperative hip function and complication rate.

ABSTRACT

Cordyceps, a unique precious Chinese herbal medicine in China, has the effects of tonifying the kidney and lungs, stopping bleeding, and resolving phlegm. It has definite clinical effects on diabetes, respiratory diseases (such as chronic obstructive pulmonary disease), chronic kidney diseases, slow arrhythmia, and hyperlipidemia. We searched China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, SpringerLink (Biomedical Sciences), Embase, Proquest (Life Sciences), PubMed, Cochrane Library, and SinoMed for the research on the arsenic content in Cordyceps. According to statistical analysis, arsenic in Cordyceps mainly exists in the non-toxic or low-toxic form. The arsenic-containing compounds in Cordyceps may be an arsenic-sugar compound with anticancer effect. The inorganic arsenic content in Cordyceps is lower than the arsenic standard stipulated by the State Food and Drug Administration. It remains uncertain whether different measurement methods can affect the results. The total arsenic content varies in Cordyceps from different producing areas, and the general rule of total arsenic content in Cordyceps produced in different provinces, districts, and counties cannot be obtained from the results of the existing studies. The arsenic content in Cordyceps is mainly concentrated in the insect part, which is significantly different from that in stroma, and no arsenic is detected in the mycelia. The soil arsenic content in the growing areas is generally high, which may be a main reason for the high arsenic content in Cordyceps. As a valuable medicinal material for tonifying and nourishing, Cordyceps still plays an irreplaceable role in disease prevention, health care, chronic disease management, and rehabilitation.

ABSTRACT

Objective An X-shaped cushioning insole with variable stiffness was designed to explore its effects on plantar pressure and internal stress of diabetic patients with toe amputation. Methods Based on CT images, the feet-calf finite element model of diabetic patients with toe amputation was established, and the insole was divided into different areas according to distribution characteristics of the planter pressure. The three-dimensional (3D) printed cushioning insole with an X-shaped sandwich structure was designed. The modulus of the sandwichstructure was changed by changing thickness of the sandwich structure panel. For simulation analysis, the divided area was filled with the X-shaped sandwich structure with different modulus. Results The peak plantar pressure of diabetic patients with toe amputation was in calcaneal region, and the combined insoles with 1. 2 mpanel thickness in toe area, 1. 4 mm panel thickness in metatarsal area, 2. 0 mm panel thickness in middle area and 1. 6 mm panel thickness in heel area had the best decompression effect. Compared with bare feet, the peak pressure in heel area of the insole, the peak pressure in phalangeal head area and the stress in plantar softissues were reduced by 40. 18% , 31. 7% , and 50. 44% , respectively. Conclusions The 3D printed insoles with variable stiffness can effectively reduce surface pressure and internal stress of the sole and reduce probability of the 2nd toe amputation

ABSTRACT

Objective@#To investigate the changes of ambient dose equivalent rate in 99mTcO4- single photon emission computed tomography (SPECT) of the thyroid among patients with hyperthyroidism, so as to provide insights into radiation protection guidance.@*Methods@#Patients with hyperthyroidism who underwent 99mTcO4- SPECT of the thyroid in a tertiary hospital were enrolled. The ambient dose equivalent rate was measured at different time points following 99mTcO4- infection and at sites with different distances from patients' neck, and the effects of time post-injection, distance from patients' neck, 24-hour thyroidal radioiodine uptake and thyroid weight on the ambient dose equivalent rate were examined using a generalized linear mixed model.@*Results@#Totally 100 patients with hyperthyroidism were enrolled, including 24 men and 76 women and with a mean age of (38.5±14.0) years. The generalized linear mixed model was statistically significant (F=6 610.165, P<0.001), and patients' thyroid weight, time post-injection and distance from patients' neck significantly affected the ambient dose equivalent rate (F=57.967, 15 988.574, 11 200.645, all P<0.001), and the ambient dose equivalent rate positively correlated with patients' thyroid weight and negatively correlated with time post-injection and distance from patients' neck.@*Conclusions@#The ambient dose equivalent rate is affected by patients' thyroid weight, time post-injection and distance from patients' neck among patients with hyperthyroidism undergoing 99mTcO4- SPECT of the thyroid. Delay in contact with patients or keeping distance from patients may be effective for radiation protection.

ABSTRACT

Coronary artery disease(CAD) caused by atherosclerosis(AS) is a major contributor to the global burden of disease. The pathogenesis of CAD is complex, and the subset and function of cardiac macrophages are important factors affecting the occurrence and development of AS and the prognosis of CAD. Recent studies have shown that some traditional Chinese medicine(TCM) formulas and active ingredients can regulate macrophage subsets involved in the inflammation, injury, and repair process of CAD. This paper summarized the significant role of macrophages in AS and myocardial infarction. Based on the plasticity of macrophages, this paper elaborated that traditional Chinese medicine prevented and attenuated AS by regulating macrophage subsets, reducing the level of inflammatory factors, and promoting macrophage autophagy.Traditional Chinese medicine participated in the cardiac repair process after myocardial infarction by accelerating the recruitment of M2 macrophages, inhibiting the polarization of M1 macrophages mediated by glycolysis, inhibiting M1 macrophage-mediated cardiac nerve remodeling, and promoting M2 macrophage-mediated angiogenesis. In addition, in vitro studies on the regulation of macrophage subsets by the active ingredients of traditional Chinese medicine were also reviewed. It was pointed out that nuclear factor kappa B(NF-κB), adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK), phosphoinositide 3-kinase/protein kinase B(PI3K/Akt), chemokine(C-C motif) ligand 2/C-C chemokine receptor type 2(CCL2/CCR2) were the key targets and pathways for the regulation of macrophages by TCM.

ABSTRACT

With the advances in medicine, people have deeply understood the complex pathogenesis of diseases. Revealing the mechanism of action and therapeutic effect of drugs from an overall perspective has become the top priority of drug design. However, the traditional drug design methods cannot meet the current needs. In recent years, with the rapid development of systems biology, a variety of new technologies including metabolomics, genomics, and proteomics have been used in drug research and development. As a bridge between traditional pharmaceutical theory and modern science, computer-aided drug design(CADD) can shorten the drug development cycle and improve the success rate of drug design. The application of systems biology and CADD provides a methodological basis and direction for revealing the mechanism and action of drugs from an overall perspective. This paper introduces the research and application of systems biology in CADD from different perspectives and proposes the development direction, providing reference for promoting the application.

ABSTRACT

This study aimed to analyze the biological foundation and biomarkers of stable coronary heart disease(CHD) with phlegm and blood stasis(PBS) syndrome based on RNA-seq and network pharmacology. Peripheral blood nucleated cells from five CHD patients with PBS syndrome, five CHD patients with non-PBS syndrome, and five healthy adults were collected for RNA-seq. The specific targets of CHD with PBS syndrome were determined by differential gene expression analysis and Venn diagram analysis. The active ingredients of Danlou Tablets were screened out from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, and the "component-target" prediction was completed through PubChem and SwissTargetPrediction. The "drug-ingredient-target-signaling pathway" network of Danlou Tablets against CHD with PBS syndrome was optimized by Cytoscape software. After the target biomarkers were identified, 90 participants were enrolled for diagnostic tests, and 30 CHD patients with PBS syndrome were included in before-and-after experiment to determine the therapeutic effect of Danlou Tablets on those targets. As revealed by RNA-seq and Venn diagram analysis, 200 specific genes were identified for CHD with PBS syndrome. A total of 1 118 potential therapeutic targets of Danlou Tablets were predicted through network pharmacology. Through integrated analysis of the two gene sets, 13 key targets of Danlou Tablets in the treatment of CHD with PBS syndrome were screened out, including CSF1, AKR1C2, PDGFRB, ARG1, CNR2, ALOX15B, ALDH1A1, CTSL, PLA2G7, LAP3, AKR1C3, IGFBP3, and CA1. They were presumably the biomarkers of CHD with PBS syndrome. The ELISA test further showed that CSF1 was significantly up-regulated in the peripheral blood of CHD patients with PBS syndrome, and was significantly down-regulated after Danlou Tablets intervention. CSF1 may be a biomarker for CHD with PBS syndrome, and it is positively correlated with the severity of the disease. The diagnostic cut-off of CSF1 for CHD with PBS syndrome was 286 pg·mL~(-1).

ABSTRACT

AIM: To investigate the effect of orthokeratology lens on ocular surface and meibomian gland in children and adolescents of different ages.METHODS: A total of 120 cases(240 eyes)of myopic children and adolescents treated in the optometry clinic of our hospital from December 2020 to February 2021 were retrospectively selected, and they were divided into the orthokeratology group(60 cases, 120 eyes)and the frame glasses group(60 cases, 120 eyes)according to the myopia correction methods. The changes in ocular surface and meibomian gland after wearing glasses were analyzed, and those changes in patients of different ages were compared between the two groups.RESULTS: Corneal curvature decreased, non-invasive tear film break-up time(NIBUT)shortened and meibomian gland score increased at 3, 6, 9 and 12mo in the orthokeratology group after wearing lens, while lower tear meniscus height increased at 6, 9 and 12mo compared with that before wearing lens. In the frame glasses group, the lower tear meniscus height was higher at 6 and 9mo than that before wearing glasses(both P&#x003C;0.05). At the same time point, the corneal curvature of the orthokeratology group was significantly lower than that of the frame glasses group at all time points, the NIBUT at 3, 9 and 12mo after wearing the lens was shorter than that of the frame glasses group and the meibomian gland scores were higher at 6, 9 and 12mo than those at the same time point in the glasses group(all P&#x003C;0.05). After wearing lens for 12mo, the corneal curvature of the orthokeratology group at all ages was significantly lower than that of the frame glasses group, the NIBUT of the orthokeratology group at 8 to 12 years old and 13 to 15 years old was significantly lower than that of the frame glasses group, and the meibomian gland score was significantly higher than that of the frame glasses group(all P&#x003C;0.05).CONCLUSION: Orthokeratology lens may affect the ocular surface and meibomian glands function, and the effects on ocular surface are more pronounced in children and adolescents under 12 years old. Therefore, younger children and adolescents could be prioritized for myopia correction with framed glasses, and then wearing orthokeratology lens when they get older.

ABSTRACT

OBJECTIVE@#To analyze the expression of hydroxysteroid dehydrogenase like 2 (HSDL2) in rectal cancer tissues and the effect of changes in HSDL2 expression level on proliferation of rectal cancer cells.@*METHODS@#Clinical data and tissue samples of 90 patients with rectal cancer admitted to our hospital from January 2020 to June 2022 were collected from the prospective clinical database and biological specimen database. The expression level of HSDL2 in rectal cancer and adjacent tissues was detected by immunohistochemistry, and based on the median level of HSDL2 expression, the patients were divided into high expression group (n=45) and low expression group (n=45) for analysis the correlation between HSDL2 expression level and the clinicopathological parameters. GO and KEGG enrichment analyses were performed to explore the role of HSDL2 in rectal cancer progression. The effects of changes in HSDL2 expression levels on rectal cancer cell proliferation, cell cycle and protein expressions were investigated in SW480 cells with lentivirus-mediated HSDL2 silencing or HSDL2 overexpression using CCK-8 assay, flow cytometry and Western blotting.@*RESULTS@#The expressions of HSDL2 and Ki67 were significantly higher in rectal cancer tissues than in the adjacent tissues (P < 0.05). Spearman correlation analysis showed that the expression of HSDL2 protein was positively correlated with Ki67, CEA and CA19-9 expressions (P < 0.01). The rectal cancer patients with high HSDL2 expressions had significantly higher likelihood of having CEA ≥5 μg/L, CA19-9 ≥37 kU/L, T3-4 stage, and N2-3 stage than those with a low HSDL2 expression (P < 0.05). GO and KEGG analysis showed that HSDL2 was mainly enriched in DNA replication and cell cycle. In SW480 cells, HSDL2 overexpression significantly promoted cell proliferation, increased cell percentage in S phase, and enhanced the expression levels of CDK6 and cyclinD1 (P < 0.05), and HSDL2 silencing produced the opposite effects (P < 0.05).@*CONCLUSION@#The high expression of HSDL2 in rectal cancer participates in malignant progression of the tumor by promoting the proliferation and cell cycle progress of the cancer cells.

ABSTRACT

Standardisation and harmonisation of the detection of autoantibodies is important for the clinical application of autoantibodies. However, achieving complete standardisation is difficult and involves several challenges due to the complexity and particularity of autoantibody detection. Harmonisation is feasible and valued, but it involves all aspects and processes of autoantibody detection. Based on the consensus and practice of the clinical application of autoantibody detection in recent years, we discuss harmonisation in this review.

OBJECTIVE@#To explore prevalence, risk factors and treatment of ankle sprain of young college student , in order to obtain accurate epidemiological data.@*METHODS@#From March 2019 to May 2019, 552 college students(1 104 sides of anke joints) from Xi'an Physical Education university were enrolled in study according to inclusion and excludion standard, including 309 males and 243 females aged from 16 to 24 years old with an average of (20.9±3.7) years old. Age, gender, and body mass indes(BMI) etc were recorded. Morbidity of acute and chronic ankle sprains of physical students, treatment after the first sprain (cold compress, cast or plaster bracing and medicine), visual analogue scale (VAS) during walking were assessed through ankle sprain questionnaire;Cumberland ankle instability tool (CAIT), Maryland foot score were applied to assess ankle function. Lateral ankle ligament injury was objectively assessed by musculoskeletal ultrasonography.@*RESULTS@#The prevalence of acute ankle sprain(AAS) was 96.20% (531/552), and the incidence of AAS was 59.96% (622/1 104). The prevalence of chronic ankle joint instability(CAI) was 16.85% (93/552), and the incidence of CAI was 8.97% (99/1 104). In the four categories of sports, college student suffered from multiple sprains in performance majors group was 22.20% (14/63), including of aerobicsand dance performance. The incidence of AAS of ball sports was 8.60%(14/163). After the first sprain, most college students(94.4%) were received cold compression, about 60% of them went to hospital;however, only 44.7% students were received standard treatmens(cast or plaster), only 35.3% of them were received hard ankle orthosis. In 552 college students, 44 students were suffered from more than 4 times of ankle sprain, and the total incidence was 7.97% (44/552). Cumberland score was 26.6±2.4, Cumberland score of students sprained ankle joint more than 4 times was (29.2±1.1), suggested it was a risk factor for ankle joint instability. VAS of students sprained ankle joint more than 4 times was higher than that of less than 4 times(P<0.05), Maryland foot score was significantly lower than that of that of <4 times(P<0.05). Musculoskeletal ultrasonography measured the thickness of anterior tibiofibular ligament(ATFL) was (2.41±0.41) mm, and the thickness of calcaneofibular ligament(CFL) was (1.92±0.21) mm, and had no statistical difference(P>0.05).@*CONCLUSION@#Ninty-four percent college students had at least once ankle sprain, ankle sprains were more common in erobics and ball sports. After the first sprain, the proportion of cast or plaster treatment was less than 50%. Sprained ankle joint more than 4 times is a risk factor, and musculoskeletal ultrasonography showed thickening of both ATFL and CFL, while no statstical difference.

ABSTRACT

AIM: To investigate the mechanism of pyrrolidine dithiocarbamate(PDTC)on transforming growth factor-beta 2(TGF-β2)-induced epithelial-mesenchymal transition(EMT)in human lens epithelial cells(LECs).METHODS: LECs were treated with various doses of PDTC chemicals following TGF-β2 caused EMT on these cells. Cell proliferation and lateral migration were discovered using the CCK-8 and cell scratch test. The markers of EMT, including E-cadherin, α-SMA and nuclear factor-κB(NF-κB)signaling pathway-related expression, were tested by Western Blot as well as the changes in the expression of the apoptosis-related proteins BAX, BCL-2, Caspase-3, and Cyclin D1.RESULTS: The proliferation and migration viability of cells in the TGF-β2 treated group was increased compared to the group without TGF-β2, and the expression of α-SMA increased whereas the E-cadherin expression decreased. With the effect of TGF-β2, NF-κB p65 and phosphorylated NF-κB p65 expression increased, the concentration of TGF-β2 that had the greatest capacity for proliferation and migration was 10 ng/mL(P&#x003C;0.05). Mechanism study of PDTC-induced EMT reversal and apoptosis showed that cell viability and migratory capability were both significantly reduced after PDTC intervention; PDTC prevents IκB phosphorylation, thus inhibiting NF-κB nuclear translocation. Protein associated to the NF-κB signaling pathway, and protein expression of NF-κB/IκBα/p-IκBα/Iκκ-α/p-Iκκ-α was decreased(P&#x003C;0.05), PDTC increased the expression of the pro-apoptotic protein BAX/Caspase-3, expression of the inhibitor of apoptosis protein BCL-2 and the cell cycle protein Cyclin D1 was reduced. The expression of NF-κB/IκB mRNA was reduced, expression of the apoptosis-related mRNA BAX increased, while BCL-2 reduced.CONCLUSION: The EMT in LECs cells induced by TGF-β2 can be significantly reversed by PDTC, which may be related to the decreased expression of NF-κB p65/IκB/Iκκ-α and activation of apoptosis-related protein. PDTC can reverse EMT by inhibiting NF-κB signaling pathway and induce apoptosis of abnormally proliferated cells, which will provide new potential therapeutic agents for posterior capsular opacification(PCO)treatment.

ABSTRACT

ObjectiveTo analyze the characteristics of plantar pressure of diabetic patients during gait cycle, and to design a offloading insole with variable stiffness. MethodsThe plantar pressure experiment was carried out and a database including 157 subjects was established. The differences of plantar pressure distribution were analyzed among diabetic patients with and without peripheral neuropathy, and healthy people. The insole pressure area was divided, and porous units were filled in different insole areas according to the pressure gradient. The fed-calf-insole finite element model of diabetic patients was constructed. The simulation analysis of different insole schemes was carried out under the conditions of push-off, footheel-strike and dynamic neutrality posture, and to explore the most reasonable insole stiffness design. ResultsCompared with the healthy group, the percentage of peak pressure and high pressure in the left and right heel areas of diabetic neuropathy patients showed a decreasing trend, in which the left peak pressure was significantly reduced by 11% (P = 0.026) and the percentage of high pressure was significantly reduced by 9.8% (P = 0.02). When the porous elements of 2.5 MPa and 1.9 MPa were used in the high pressure area of the insole metatarsal and high pressure area of the heel, the peak plantar pressure of footheel-strike, dynamic neutral and push-off was reduced by 42.4%, 27.4% and 26.4%, and the peak stress of the soft tissue was reduced by 49.8%, 43.6% and 25.1%, respectively. ConclusionThere is a higher risk of ulcer in the metatarsal region than in the heel region for diabetic patients. The variable stiffness insoles based on the optimization of plantar pressure and internal stress under multi-posture can effectively reduce the peak pressure of plantar and peak stress of soft tissue during walking, which provides a reference for the design of variable stiffness insoles.

ABSTRACT

Peri-implant disease, an important group of diseases that cause implant failure, are associated with metabolic abnormality. Metabolic syndrome (MetS) is a common metabolic disorder comprising abdominal obesity, hyperglycemia, systemic hypertension and atherogenic dyslipidemia. Previous studies had reported that MetS and its diversified clinical manifestations might be associated with peri-implant diseases, but the relationship and underlying mechanisms were unclear. This review aims to explore the relationship between MetS and peri-implant disease, in order to provide beneficial reference for the prevention and treatment of peri-implant disease in patients with MetS.
