ABSTRACT
Objective To detect the levels of serum collagen type Ⅰ alpha 1 chain(COL1A1)and collagen type Ⅰ alpha 2 chain(COL1A2)in patients with intracranial aneurysm(IA),and explore their correlations with aneurysm rupture.Methods A total of 110 IA patients admitted to our hospital were regarded as the IA group and another 100 volunteers who underwent physical examination in our hospital were regarded as the control group.The expression levels of serum COL1A1 and COL1A2 were detected by ELISA.The IA patients were divided into the ruptured group(n=66)and unruptured group(n=44)according to the presence or absence of aneurysm rupture,and the clinical data and expression levels of serum COL1A1 and COL1A2 were compared between the two groups.The expression levels of serum COL1A1 and COL1A2 in patients with different Hunt-Hess grades were compared.The risk factors of aneurysm rupture in patients with IA were analyzed by multivariate Logistic regression analysis.The predictive value of serum COL1A1 and COL1A2 for aneurysm rupture in patients with IA were evaluated by receiver operating characteristic(ROC)curve.The correlation of serum COL1A1 and COL1A2 with Hunt-Hess grade for patients in rupture group was analyzed by Spearman correlation analysis.Results The expression levels of serum COL1A1 and COL1A2 for patients in the IA group were significantly higher than those in the control group(P<0.05).The number of patients with hypertension,diabetes mellitus,hyperlipidemia,aneurysm diameter>10 mm,and the expression levels of serum COL1A1 and COL1A2 in the rupture group were significantly more/higher than those in the unruptured group(P<0.05).The expression levels of serum COL1A1 and COL1A2 in patients with Hunt-Hess grades from Ⅲ to Ⅳ were significantly higher than those in patients with grades from Ⅰ to Ⅱ(P<0.05).The expression levels of serum COL1A1 and COL1A2 for patients in the rupture group were positively correlated with Hunt-Hess grade(r=0.562,0.414,P<0.05).Multivariate Logistic regression analysis showed that hypertension,diabetes mellitus,aneurysm diameter>10 mm,and increased expression levels of COL1A1 and COL1A2 were risk factors for aneurysm rupture in IA patients(P<0.05).The area under the curve(AUC)of aneurysm rupture predicted by serum COL1A1 and COL1A2 together was significantly higher than that predicted by COL1A1 alone(Z=1.905,P=0.028)and COL1A2 alone(Z=1.754,P=0.040).Conclusion The increased expression levels of serum COL1A1 and COL1A2 are risk factors for aneurysm rupture in patients with IA,and their combined prediction of aneurysm rupture in IA patients has certain clinical value.
ABSTRACT
Intraosseous regional administration (IORA) combines intraosseous infusion with tourniquet technology, using the tourniquet to limit the distribution of drugs in the target limb, achieving higher tissue concentration than systemic administration. In recent years, IORA technology has gained widespread attention and application in total knee arthroplasty (TKA). At present, prophylactic antibiotics are mainly administered in TKA by IORA technology. Studies have shown that drug concentration in local tissues can be significantly increased by IORA before TKA. In addition, there are also studies using IORA technology for preoperative analgesia in TKA, and good early postoperative analgesia effect has been obtained. However, it is unclear whether giving antibiotics through IORA technology is effective in preventing artificial joint infections. At the same time, there is still controversy as to whether IORA will increase complications such as puncture site accidents and fat embolism. This study reviews the current research on the use of IORA in TKA and shows that the application of IORA in TKA will not increase the incidence of complications and can significantly increase the local drug concentration. In primary TKA, IORA technology may have advantages over traditional intravenous systemic administration in terms of postoperative infection prevention and pain control. However, the efficacy of prophylactic antibiotics administered through IORA technology is unclear in people at high risk of infection such as obesity, diabetes, and modified TKA.
ABSTRACT
Objective:To investigate the perioperative total blood loss of robot-assisted total knee arthroplasty (TKA).Methods:A total of 60 patients with knee osteoarthritis who underwent initial unilateral TKA in Peking Union Medical College Hospital from February to June 2022 were retrospectively analyzed. According to whether they received robot-assisted surgery, they were divided into robot-assisted group and traditional surgery group. In the robot-assisted group, there were 32 patients, including 6 males and 26 females, aged 70.22±5.88 years (range, 57 to 79 years). Left side 14 cases, right side 18 cases; grade of Kellgren-Lawrence: 1 case of grade Ⅱ, 14 cases of grade Ⅲ, 17 cases of grade Ⅳ. In the traditional surgery group, there were 28 patients, including 5 males and 23 females, aged 68.61±6.79 years (range, 57 to 87 years). Left side 16 cases, right side 12 cases; grade of Kellgren-Lawrence: 2 cases of grade Ⅱ, 12 cases of grade Ⅲ, 14 cases of grade Ⅳ. There was no significant difference in baseline data between the two groups ( P>0.05). Postoperative hemoglobin, hematocrit, and their decreased values were recorded in the two groups, and perioperative range of motion (ROM) of knee and Hospital for Special Surgery (HSS) scores were compared between the two groups. Results:All patients successfully completed the surgery and were followed up, with a follow-up time of 9.93±0.83 months (range, 8-11 months) in the robotic-assisted group and 9.59±0.97 months (range, 8-11 months) in the traditional surgery group. The application time of tourniquet in the robot-assisted group was 96.19±10.21 min, which was higher than that in the traditional surgery group (62.68±16.54 min), and the difference was statistically significant ( t=9.57, P<0.001). The total perioperative blood loss in the robot-assisted group was 534.59(411.85, 859.26) ml, which was higher than 411.32(313.42, 613.52) ml in the traditional surgery group, and the difference was statistically significant ( Z=-2.37, P=0.018). There were no significant differences in hemoglobin or hematocrit between the two groups at day 1 and 3 after surgery ( P>0.05). The hemoglobin decrease value in the robotic-assisted group was 19.63±9.73 g/L, which was greater than 14.71±5.84 g/L in the traditional surgery group, and the difference was statistically significant ( t=2.40, P=0.020). The decrease value of hematocrit in the robot-assisted group was 5.77%±3.14%, which was greater than 4.09%±1.57% in the traditional operation group ( t=2.56, P=0.013). At the last follow-up, knee ROM of the two groups were 123.03°±5.91° and 125.82°±6.59°, respectively, which were higher than the preoperative values of 95.69°±11.64° and 90.29°±23.08°. Postoperative HSS scores were 89.50±4.19 points and 90.70±4.34 points, which were higher than 62.58±10.52 points and 61.09±12.66 points before operation, the differences were statistically significant ( P<0.05), and there was no significant difference between groups ( P>0.05). There were 6 cases of postoperative deep vein thrombosis of the lower extremities in the robot-assisted group and 2 cases in the traditional surgery group, and the difference was not statistically significant (χ 2=0.88, P=0.348). Conclusion:Compared with traditional TKA, robotic-assisted TKA increased perioperative blood loss, and there was no difference in postoperative knee function between the two groups.

ABSTRACT
Aim To investigate the role of FKBP38 in inhibiting apoptosis in a rotenone-induced Parkinson's disease(PD)cell model. Methods In vivo experiments:MPTP-induced PD in vivo models were constructed,and the expressions of α-synuclein,TH and FKBP38 in brains of PD mice were detected. In vitro experiments:Dopaminergic neuron MN9D cells were stimulated with rotenone to construct an in vitro model of PD; Western blot was used to detect the expression levels of α-synuclein,TH,Tom20 and FKBP38 in PD in vitro model; FKBP38 lentivirus was transferred into MN9D cells to construct stable overexpression and FKBP38 knockdown cell lines; CCK-8 assay was used to detect the cell viability of FKBP38 overexpression and knockdown cells stimulated by rotenone; Western blot was used to detect anti-apoptotic protein Bcl-2 and apoptosis protein in PD cell model expression levels of Bax. Results The expression level of FKBP38 was significantly down-regulated in both in vitro and in vivo models of PD(P<0.01). Knockdown of FKBP38 aggravated the decline of dopaminergic neuron cell viability caused by rotenone(P<0.05),while overexpression of FKBP38 significantly ameliorated the decline of dopaminergic neuron cell viability caused by rotenone(P<0.05). Western blot results showed that overexpression of FKBP38 could significantly up-regulate the expression level of anti-apoptotic protein Bcl-2 and increase the ratio of Bcl-2/Bax in PD dopaminergic neurons(P<0.05). Conclusion In the PD cell model regulation of FKBP38 can improve the apoptosis of dopaminergic neurons.
ABSTRACT
Aim To investigate the effects of CPD1,a novel phosphodiesterase 5 inhibitor,on renal pathological phenotype and fibrotic protein expression in renal fibrosis model mice. Methods Male C57BL/6 J mice were divided into three groups randomly(sham group,UUO group and UUO+CPD1 group). Unilateral ureteric obstruction model was constructed by surgery,and CPD1(5 mg·kg-1·d-1)was administered by intragastric administration two hours after the modeling for seven days. HE and Sirius Red staining were used to observe the distribution of tissue structural lesions and fibrosis. Immunohistochemical staining and Western blot were used to detect the expression of fibronectin(FN),α-SMA,collagen-I and kidney injury molecule-1(Kim-1). Results Compared with sham operation group,the renal tubules of mice were dilated and accompanied by a large amount of inflammatory infiltration. Moreover,the expressions of FN,α-SMA,collagen-I and Kim-1 proteins increased significantly(P<0.05)in UUO group. CPD1 treatment improved the kidney structure and decreased the expression of collagen fibers. Furthermore,CPD1 inhibited the expression of FN,α-SMA,collagen-I and Kim-1 markedly(P<0.05). Conclusions Phosphodiesterase 5 inhibitor CPD1 alleviates the progression of renal fibrosis induced by unilateral ureteral obstruction through down-regulating ECM deposition in the extracellular matrix and expression of Kim-1. The specific mechanism remains to be further studied.
ABSTRACT
BACKGROUND@#Total knee arthroplasty (TKA) can reduce severe joint pain and improve functional disability in hemophilia. However, the long-term outcomes have rarely been reported in China. Therefore, this study aimed to evaluate the long-term outcomes and complications of TKA in Chinese patients with hemophilic arthropathy.@*METHODS@#We retrospectively reviewed patients with hemophilia who underwent TKA between 2003 and 2020, with at least 10 years of follow-up. The clinical results, patellar scores, patients' overall satisfaction ratings, and radiological findings were evaluated. Revision surgery for implants during the follow-up period was recorded.@*RESULTS@#Twenty-six patients with 36 TKAs were successfully followed up for an average of 12.4 years. Their Hospital for Special Surgery Knee Score improved from an average of 45.8 to 85.9. The average flexion contracture statistically significantly decreased from 18.1° to 4.2°. The range of motion (ROM) improved from 60.6° to 84.8°. All the patients accepted patelloplasty, and the patients' patellar score improved from 7.8 preoperatively to 24.9 at the last follow-up. There was no statistically significant difference in clinical outcomes between the unilateral and bilateral procedures, except for a better ROM at follow-up in the unilateral group. Mild and enduring anterior knee pain was reported in seven knees (19%). The annual bleeding event was 2.7 times/year at the last follow-up. A total of 25 patients with 35 TKAs were satisfied with the procedure (97%). Revision surgery was performed in seven knees, with 10- and 15-year prosthesis survival rates of 85.8% and 75.7%, respectively.@*CONCLUSIONS@#TKA is an effective procedure for patients with end-stage hemophilic arthropathy, which relieves pain, improves knee functions, decreases flexion contracture, and provides a high rate of satisfaction after more than ten years of follow-up.

Conventional wisdom holds that the onset of chronic obstructive pulmonary disease (COPD) is usually in older people. However, with extended follow-up in large cohort studies, the trajectory of lung function development has been gradually delineated, indicating that the decline of lung function may originate early in life. In addition, a large number of studies have shown that people with chronic respiratory symptoms, pulmonary imaging changes and abnormal lung physiology, but not in line with pulmonary function diagnosis of COPD, tend to develop COPD in the future and may have a worse prognosis, suggesting the necessity of early intervention. The GOLD 2022 report proposes a series of terms related to COPD, including COPD in young people and pre-COPD, opening up new opportunities for the prevention, early diagnosis and treatment of COPD. These concepts also guide the study design of the biological mechanism of COPD and the trajectory of disease progression. This article reviews the research progress of COPD in young people and pre-COPD to attract more attention in clinical practice.

The American College of Rheumatology (ACR) and the American Association of Hip and Knee Surgeons (AAHKS) convened a writing group to develop a consensus report on the management of anti-rheumatic medication in patients with rheumatic diseases undergoing elective total hip or total knee arthroplasty in June 2022. In particular, the consensus provides significant updates on target synthetic disease modifying anti-rheumatic drugs and perioperative medication management in patients with systemic lupus erythematosus, as well as the addition of newly approved antirheumatic medications for administration. This article will interpret the consensus and provide a reference for the perioperative management of antirheumatic medications for hip and knee arthroplasty in patients with rheumatic diseases in China.
ABSTRACT
Objective@#To investigate the milk drinking behavior and bone mineral density level of pupils in Hainan Province, and to explore the correlation between bone mineral density and milk drinking behavior, in order to provide scientific basis for promoting the healthy development of bones in children and adolescents.@*Methods@#In November 2021, a cross sectional survey including demographic characteristics, milk intake, unhealthy eating behavior, physical activity and sleep was conducted among 696 students from grades 3 to 5 in Sanya and Baisha, Hainan by stratified cluster random sampling, and bone mineral density at the distal 1/3 of the right forearm was measured by dual energy X-ray absorptiometry. t-test was used to compare the differences in bone mineral density among different milk drinking behaviors of pupils, and multiple linear regression was used to analyze the correlation between milk consumption and bone mineral density.@*Results@#About 25.3% students consumed milk daily and 13.9% consumed ≥ 300 g of milk daily. The mean bone mineral density at the distal 1/3 of the right forearm was (0.237±0.041)g/cm 2. The bone mineral density was greater in the group with daily milk intake than in the group without daily milk intake [(0.250± 0.037 )(0.204±0.034) g/cm 2 , t=15.00, P <0.01], and the bone mineral density was greater in the group with daily average milk intake ≥300 g than in the group with daily average milk intake <300 g [(0.284±0.036)(0.229±0.037)g/cm 2, t=13.48, P < 0.01 ]. Multiple linear regression analysis showed that daily average milk intake was positively correlated with bone mineral density, with a correlation coefficient ( β=0.020, t=21.46, P <0.01).@*Conclusion@#Milk consumption among pupils is inadequate, and milk drinking behavior has a positive impact on bone mineral density, so effective milk drinking intervention should be carried out to promote children s bone development.
ABSTRACT
A young male diagnosed with severe hemophilia A since childhood, was presented with recurrent joint and urinary bleeding. Annualized bleed rates dropped below five with low dose prophylactic medication.Bleeding in the right knee joint recently aggravated. Due to coexisting HIV infection and advanced hemophilic arthritis, the patient was managed by a multi-disciplinary team(MDT).Total knee arthroplasty was performed by an experienced surgeon using modern prosthesis design and intraoperative navigation technologies.Physical and rehabilitation therapy was provided during the postoperative period, and joint function improved. The MDT managed the young patient with HIV infection and advanced hemophilic arthritis. The patient was diagnosed with osteoporosis thought to have been caused by hemophilia, HIV infection and antiviral drugs; and he received treatment. The treatment of this patient reflects the importance of multidisciplinary cooperation in the management of difficult and rare diseases.
ABSTRACT
This study analyzed the effects of male age and abstinence time on semen quality and explored the best abstinence time for Chinese males among different age groups. Semen parameters, including sperm kinetics, morphology, and DNA fragmentation index (DFI), were reviewed from 2952 men. Samples were divided into six age groups (≤25 years, 26-30 years, 31-35 years, 36-40 years, 41-45 years, and >45 years) and were divided into six groups according to different abstinence time (2 days, 3 days, 4 days, 5 days, 6 days, and 7 days). The differences in semen quality between the groups were compared, and the effect of age and abstinence time on semen quality was analyzed. Significant differences were observed in semen volume, progressive motility (PR), and DFI among the age groups (all P < 0.05), and no significant differences were observed in sperm morphological parameters (all P > 0.05). There were significant differences in semen volume, PR, and DFI among different abstinence time groups (all P < 0.05) and no significant differences in sperm morphological parameters (all P > 0.05). Pearson analysis showed that male age and abstinence time were both significantly correlated with sperm kinetics and DFI (both P < 0.05), while no significant correlation was found with sperm morphological parameters (all P > 0.05). The box plots and histograms of men's age, abstinence time, and semen quality show that most semen quality parameters differ significantly between the 2 days and 7 days abstinence groups and other groups at different ages. Except for the sperm morphology parameters, sperm kinetic parameters and sperm DFI are linearly related to male age and abstinence time.

Objective:To investigate the optimal monochromatic level for evaluation of in-stent lumen after transjugular intrahepatic portosystemic shunt (TIPS) by dual-layer detector CT.Methods:Twenty-nine patients after TIPS were retrospectively enrolled who underwent abdomen enhanced examinations with portal venous phases by a dual-layer detector CT between December 2019 and July 2021. The mixed iterative image (conventional group) and monochromatic images (40 keV group, 50 keV group, 60 keV group and 70 keV group) were obtained by reconstruction. Circular regions of interest were placed in the in-stent of the cross-sectional reconstructed image and in the vertical spinal muscle on the same plane to obtain the corresponding average CT value and noise. The contrast to noise ratio (CNR) and signal to noise ratio (SNR) were calculated. Then 4-point scale was performed to evaluate image quality subjectively by 2 physicians blindly and separately. One-way ANOVA or Kruskal Wallis H rank-sum test was used for the overall analysis between groups, and LSD test or Dunn′s Bonforoni test was used for pairwise comparison within groups. Results:There was no significant difference in noise values among the 5 groups ( P>0.05). The difference of CNR and SNR between the 5 groups was statistically significant ( F=72.28, 56.45, P<0.001). The CNR and SNR in the 40 keV group were the highest, which were 50.4±15.7 and 59.3±18.4 respectively, and the difference was statistically significant ( P<0.001). Subjective scores showed statistically significant differences among the 5 groups (χ2=101.61, P<0.001). The score of the 40 keV group was higher than that of the 60 keV group, 70 keV group, and conventional group ( P<0.001), and there was no significant difference when compared with the subjective score of the 50 keV group ( P>0.05). Conclusions:The 40 keV monochromatic image of dual detector spectral CT is the best image to observe the lumen of the stent after TIPS.
ABSTRACT
Mandibular defects caused by injuries, tumors, and infections are common and can severely affect mandibular function and the patient's appearance. However, mandible reconstruction with a mandibular bionic structure remains challenging. Inspired by the process of intramembranous ossification in mandibular development, a hierarchical vascularized engineered bone consisting of angiogenesis and osteogenesis modules has been produced. Moreover, the hierarchical vascular network and bone structure generated by these hierarchical vascularized engineered bone modules match the particular anatomical structure of the mandible. The ultra-tough polyion complex has been used as the basic scaffold for hierarchical vascularized engineered bone for ensuring better reconstruction of mandible function. According to the results of in vivo experiments, the bone regenerated using hierarchical vascularized engineered bone is similar to the natural mandibular bone in terms of morphology and genomics. The sonic hedgehog signaling pathway is specifically activated in hierarchical vascularized engineered bone, indicating that the new bone in hierarchical vascularized engineered bone underwent a process of intramembranous ossification identical to that of mandible development. Thus, hierarchical vascularized engineered bone has a high potential for clinical application in mandibular defect reconstruction. Moreover, the concept based on developmental processes and bionic structures provides an effective strategy for tissue regeneration.

ABSTRACT
Objective:To explore the influence of intensive analgesia on the incidence of post-traumatic stress disorder (PTSD) in acute trauma patients, and to develop new ideas for the prevention and treatment of PTSD.Methods:From January 2018 to November 2019, a prospective study was conducted on trauma patients who visited the Emergency Center of Affiliated Hospital of Xuzhou Medical University and met the enrollment criteria. The patients were divided into the intensive analgesia group (< 4) and non-intensive analgesia group (≥ 4) according to the mean pain score in 30 days. The epidemiological data, trauma-related parameters, analgesic schemes, VAS score, PCL-5 score, HADS score and incidence of PTSD of enrolled patients were collected. Appropriate statistical methods were used to analyze differences among the indicators between the two groups.Results:Eighty-four acute trauma cases were included in the study, 39 cases in the intensive analgesia group and 45 in the non-intensive analgesia group. There was no significant difference in baseline data between the two groups (all P>0.05). The incidence rate of PTSD and PCL-5 score of patients in the intensive analgesia group were all significantly lower than those in the non-intensive analgesia group in 1 month after the trauma (all P< 0.05). The HADS anxiety and depression scores of patients in the intensive analgesic group were significantly lower than those in the non-intensive analgesic group (all P< 0.05). All the analgesics were converted into the dosage of dezocine for comparison. The total dosage of analgesics (dezocine) used in patients of the intensive analgesia group was significantly higher than that in the non-intensive analgesia group within 30 days after injury ( P< 0.05). Conclusion:In the acute trauma patients, intensive analgesia after trauma can significantly reduce the incidence of PTSD as well as improve anxiety and depression symptoms.
ABSTRACT
Objective:To investigate the relationship between the changes in inflammatory markers levels and the onset of post-traumatic stress disorder (PTSD) in the early stage of acute trauma..Methods:From January 2018 to June 2020, patients with acute trauma who were admitted to the Affiliated Hospital of Xuzhou Medical University were selected as subjects. Peripheral venous blood was collected on admission, on the 3rd and 7th day after trauma for routine blood test, C-reactive protein (CRP) and procalcitonin (PCT). The neutrophil to lymphocyte ratio (NLR) was calculated. The PCL-5 scale was used to evaluate PTSD symptoms one month later. The patients were divided into the PTSD group and non-PTSD group with the score of 38 as the boundary. The change rule of NLR in the PTSD group and the non-PTSD group were analyzed.Results:Ninety-one trauma patients were enrolled, including 23 patients in the PTSD group and 68 patients in the non-PTSD group. Compared with the healthy control group, the NLR of 91 trauma patients on admission, on the 3rd and 7th day were significantly higher (all P< 0.01). The NLR of the PTSD group was increased on the 7th day after trauma, which was significantly higher than that of the non-PTSD group ( P= 0.025). The non-PTSD group showed a decreasing trend, of which NLR on the 7th day was significantly lower than that on admission ( P= 0.001). In addition, high level of NLR on the 7th day after trauma (β= 0.206, P= 0.01) was a risk factor for PTSD onset. Conclusions:Dynamic monitoring of the changes in NLR after acute trauma would be of great clinical value to early warning of PTSD.
