ABSTRACT
BACKGROUND:Establishing a chondrocyte model of osteoarthritis is of great significance for further explaining the pathological process of osteoarthritis and evaluating and screening the therapeutic drugs of osteoarthritis. OBJECTIVE:To evaluate the effect of interleukin-1β to induce osteoarthritis models in rat chondrocyte models,thereby providing a reference for further exploration of drug treatment of osteoarthritis. METHODS:Chondrocytes were isolated from the hip cartilage of 3-week-old Sprague-Dawley rats by mechanical shearing and enzymatic digestion,and then identified.Chondrocytes were randomly divided into three groups:control group,5 ng/mL interleukin-1β-induced group,10 ng/mL interleukin-1β-induced group,with induction times of 24 and 48 hours.Chondrocyte proliferation activity was detected by MTT.Real-Time PCR was used to detect the expression of type Ⅱ collagen,Aggrecan,sex-determining region Y-box protein 9(Sox9),matrix metalloproteinase 13,and a disintegrin and metaloproteinase with thrombospondin-like motifs-5(Adamts5)mRNA.Western blot was used to detect the expression of type Ⅱ collagen,Sox9,matrix metalloproteinase 13 and Adamts5. RESULTS AND CONCLUSION:Primary rat chondrocytes were successfully isolated and cultured.Induction of chondrocytes by interleukin-1β at 10 ng/mL for 24 hours could significantly reduce cell proliferation and viability(P<0.05),while the 5 ng/mL interleukin-1β-induced group required 48 hours of induction to cause a significant decrease in cell proliferation and viability.Real-Time PCR results showed that compared with the control group,5 or 10 ng/mL interleukin-1β induction for 24 and 48 hours significantly reduced the expression levels of type Ⅱ collagen,Aggrecan,Sox9 mRNAs(P<0.05)and increased the expression levels of matrix metalloproteinase 13 and Adamts5 mRNAs(P<0.05).Compared with the 10 ng/mL interleukin-1β-induced group,5 ng/mL interleukin-1β induction significantly increased the mRNA expression of matrix metalloproteinase 13 and Adamts5 in chondrocytes after 48 hours of induction(P<0.05).Western blot results showed that compared with the control group,10 ng/mL interleukin-1β induction for 24 hours and 5 ng/mL interleukin-1β induction for 48 hours significantly decreased the protein expression of type Ⅱ collagen and Sox9 in chondrocytes(P<0.05),and significantly increased the protein expression of matrix metalloproteinase 13 and Adamts5(P<0.05).To conclude,compared with 5 ng/mL interleukin-1β,10 ng/mL interleukin-1β may have more obvious effects on chondrocytes for 24 hours,while 5 and 10 ng/mL interleukin-1β have similar effects after 48 hours of intervention.
ABSTRACT
In order to evaluate the efficacy and safety of submucosal tunneling endoscopic resection (STER) for the treatment of multiple submucosal tumors (SMT) in the upper gastrointestinal tract, data of 24 cases with upper gastrointestinal SMT (including 56 SMT lesions) treated at Taizhou Municipal Hospital and Shanghai East Hospital from January 2016 to June 2021 were collected for retrospective observation. The treatment effect, occurrence of major adverse events and follow-up results were analyzed. The results showed that 19 cases (79.2%) underwent tumor resection through one tunnel, and 5 cases (20.8%) underwent tumor resection through two tunnels. The length of the tunnel was 3-12 cm, with an average of 6.2 cm. The surgical time ranged from 19 to 130 minutes, with an average of 55.6 minutes. The overall resection rate was 89.29% (50/56). The hospitalization time was 2-7 days, with an average of 3.5 days. Major adverse events occurred in 2 cases (8.3%), all of which were mucosal injuries, and were cured with titanium clips and self expanding metal sealing stents. During a follow-up period of 6-64 months, with an average of 32.0 months, there was no residual tumor, tumor implantation tunnel, local recurrence, distant metastasis or death. To sum up, STER is safe and feasible for the treatment of multiple SMT in the upper gastrointestinal tract. The main resection method is single tunnel, and double tunnel is required for multiple SMT far apart.
ABSTRACT
ObjectiveTo analyze the disease and functioning characteristics of older adults with sarcopenia, the main exercise rehabilitation interventions, and its health benefits. MethodsLiterature related to exercise rehabilitation for older adults with sarcopenia was searched in PubMed, Medline, Embase, Cochrane Library and CNKI, from 2013 to 2023. The quality of included systematic reviews were evaluated. ICD-11 and ICF classification systems, and PICO framework from PRISMA guideline were used to report characteristics of the disease and functioning of the population, the exercise rehabilitation interventions, and its health benefits. ResultsFinally, seven systematic reviews from Netherlands, Spain, China, Brazil and Mexico were included, covering 98 related randomized controlled trials, involving 19 794 participants. These systematic reviews mainly came from the journals in the fields of aging, rehabilitation, nutrition, public health and physical exercise, and were published between 2018 and 2023. Exercise rehabilitation for sarcopenia were categorized into three types: exercise rehabilitation, exercise rehabilitation combined with nutritional supplementation, and exercise rehabilitation combined with nursing care. Interventions primarily included aerobic training, resistance training, gait training, strength training, and balance and flexibility exercises. The intervention frequency was six to 150 minutes, one to five times a week, with intensities ranging from low to high, over a duration of six to 144 weeks. The health benefits for older adults with sarcopenia from exercise rehabilitation were reflected in improvement in physical function and structure, and enhancement in activity and participation. In terms of body function and structure, exercise rehabilitation improved muscle strength, control, coordination, gait, balance, leg extension, leg press, back strength and grip strength, and increased muscle quality. In terms of activity and participation, exercise rehabilitation improved physical activity performance, such as walking speed and time of five-repetition chair stand test. ConclusionExercise rehabilitation for sarcopenia includes exercise rehabilitation, exercise rehabilitation combined with nutritional supplementation, and exercise rehabilitation combined with nursing care. Exercise rehabilitation can improve the physical function and structure, and enhance activity and participation.
ABSTRACT
@#Objective To investigate the influence of prior percutaneous coronary intervention (PCI) on the outcome of coronary artery bypass grafting (CABG). Methods Clinical data of 5 216 patients from Jiangsu Province CABG registry who underwent primary isolated CABG from 2016 to 2019 were retrospectively analyzed. Patients were divided into a PCI group (n=673) and a non-PCI group (n=4 543) according to whether they had received PCI treatment. The PCI group included 491 males and 182 females, aged 62.6±8.2 years, and the non-PCI group included 3 335 males and 1 208 females, aged 63.7±8.7 years. Multivariable logistic regression and propensity score matching (PSM) were used to compare 30-day mortality, incidence of major complications and 1-year follow-up outcomes between the two groups. Results Both in original cohort and matched cohort, there was no statistical difference in the 30-day mortality [14 (2.1%) vs. 77 (1.7%), P=0.579; 14 (2.1%) vs. 11 (1.6%), P=0.686], or the incidence of major complications (myocardial infarction, stroke, mechanical ventilation≥24 h, dialysis for new-onset renal failure, deep sternal wound infection and atrial fibrillation) (all P>0.05). The rate of reoperation for bleeding in the PCI group was higher than that in the non-PCI group [19 (2.8%) vs. 67 (1.5%), P=0.016; 19 (2.8%) vs. 7 (1.0%), P=0.029]. Both in original cohort and matched cohort, there was no statistical difference in 1-year survival rate between the two groups [613 (93.1%) vs. 4 225 (94.6%), P=0.119; 613 (93.1%) vs. 630 (95.2%), P=0.124], while the re-admission rate in the PCI group was significantly higher than that in the non-PCI group [32 (4.9%) vs. 113 (2.5%), P=0.001; 32 (4.9%) vs. 17 (2.6%), P=0.040]. Conclusion This study shows that a history of PCI treatment does not significantly increase the perioperative mortality and major complications of CABG, but increases the rate of cardiogenic re-admission 1 year postoperatively.

ABSTRACT
@#Objective To investigate the developmental characteristics of static visual acuity (SVA) and kinetic visual acuity (KVA) and the correlation between the for children. Methods From April to June, 2018, SVA and KVA of 715 children aged 6 to 10 years in Suzhou were tested with logarithmic visual chart and KVA meter. Results KVA and SVA increased with age within 6 to 9 years old, and decreased then. KVA was higher in boys than in girls (t = 4.604, P < 0.001), but not significantly different for SVA (t = 1.822, P > 0.05). There was a moderate positive correlation between KVA and SVA (r = 0.552, P < 0.01). KVA can predicted SVA (B = 0.617, P < 0.001). Conclusion KVA and SVA develop for children aged 6 to 9, and moderately positive correlate with each other. It means SVA may be improved via training of KVA.
ABSTRACT
Objective To compare the efficacy of endoscopic sphincterotomy ( EST) combined with large-balloon dilation ( LBD) and that of LBD alone for large bile duct stones. Methods Data of 61 patients who received EST combined with LBD ( the combination group ) and 48 patients who received LBD alone ( the LBD group) from February 2008 to November 2014 were collected. The efficacy and adverse events of two groups were compared. Results The procedure time from successful cannulating to complete stone removal was shorter in the LBD group than that in the combination group [ 17. 3 min ( 8-35 min ) VS 21. 5 min ( 10-42 min) , P=0. 041] . There were no significant differences in overall complete stone removal rate[90. 2% (55/61) VS 91. 7% (44/48), P=1. 000] and complete stone removal rate without mechanical lithotripsy[78. 7% (48/61) VS 83. 3% (40/48), P=0. 542] in the combination group and the LBD group. Massive bleeding occurred in one patient of the combination group, but was successfully coagulated under endoscopy. There was no significant difference in the incidence of postoperative pancreatitis between the two groups[4. 9% (3/61) VS 6. 3% (3/48), P=1. 000]. Conclusion EST combined with LBD offers no significant advantage over LBD alone for the removal of large bile duct stones. LBD can simplify the procedure compared with EST combined with LBD in terms of shortening the procedure time.

ABSTRACT
BACKGROUND: Anterior and lateral columns of the femoral head integrity and stability have been reported to present a positive correlation with the prognosis of the osteonecrosis of the femoral head (ONFH) and efficacy of hip preserving. China-Japan Friendship Hospital Classification stressed that the retention of the anterior and lateral columns of the femoral head was of great importance to avoid the femoral head collapse, but there is little reported on its three-dimensional (3D) digital model.OBJECTIVE: To explore the method of establishing highly-simulated 3D model of China-Japan Friendship Hospital Classification for ONFH.METHODS: 3D reconstruction of normal and necrotic femoral head was established according to the CT and MRI of individuals with normal femoral head. A healthy adult male volunteer was selected and his CT image was collected; three adult male patients with types L1, L2 and L3 ONFH were selected, whose MRI images were obtained, respectively. 3D solid models were established based on CT and MRI data on Mimics 15.0, Geomagic Studio 13, Geomagic Design X, Solidworks2014 and Abauqus6.14 software. RESULTS AND CONCLUSION: A highly-simulated 3D model of L type ONFH was established, including the corticaland cancellous bones of ilium and proximal femur, articular cartilage, necrotic articular cartilage, muscles, joint capsuleand ligaments. It clearly showed the spatial structures of L type ONFH, by which different surgical programs could be compared in a virtual environment for selecting an appropriate treatment strategy to improve the success rate of hip preserving. The highly-simulated 3D model paves ways for surgical simulation and biomechanical analysis.
ABSTRACT
Objective To evaluate the effect of mild hypothermia on the expression of phosphorylated eukaryotic translation initiation factor 2α (p-eIf2αt) in the hippocampus in a mouse model of cerebral ischemia-reperfusion (I/R).Methods Sixty pathogen-free healthy male C57BL6 mice,aged 8-12 weeks,weighing 20-30 g,were divided into 3 groups (n =20 each) using a random number table:sham operation group (group S),group I/R and mild hypothermia group (group H).Cerebral I/R was induced by 15-min occlusion of bilateral common carotid arteries followed by reperfusion in chloral hydrate-anesthetized mice.Surface cooling was started immediately after reperfusion to maintain the rectal temperature at 32-34 ℃ for 3 h in group H.The neurologic deficit score was evaluated at 24 h of reperfusion.The mice were then sacrificed,brains were immediately removed,and hippocampi were isolated for examination of pathologic changes of hippocampal CA1 region and for determination of neuroapoptosis (by TUNEL) and expression of peIf2α (by Western blot).The apoptosis rate was calculated.Results Compared with group S,the neurologic deficit scores at 24 h of reperfusion and apoptosis rate of hippocampal neurons were significantly increased,and the expression of p-eIf2α was up-regulated in I/R and H groups (P<0.05).Compared with group I/R,the neurologic deficit scores at 24 h of reperfusion and apoptosis rate of hippocampal neurons were significantly decreased,and the expression of p-eIf2α was down-regulated in group H (P< 0.05).Conclusion Mild hypothermia reduces endoplasmic reticulum stress and inhibits neuroapoptosis through inhibiting the expression of p-eIf2α in the hippocampus in a mouse model of cerebral I/R.
