ObjectiveTo investigate the effectiveness of Youngswick-Akin osteotomy in the treatment of moderate hallux valgus combined with mild to moderate hallux rigidus. Methods The clinical data of 43 patients with moderate hallux valgus combined with mild to moderate hallux rigidus who were admitted between August 2019 and August 2022 and met the selection criteria were retrospectively analyzed. There were 8 males and 35 females. The age ranged from 28 to 77 years, with an average age of 59.0 years. The disease duration ranged from 10 to 35 months, with an average of 20 months. The degree of hallux rigidus included 2 cases of CoughlinⅠ degree, 29 cases of Ⅱ degree, 12 cases of Ⅲ degree. The preoperative hallux valgus angle ranged from 25° to 40°, with an average of 32°. All patients were treated with Youngswick-Akin osteotomy. The first metatarsophalangeal joint space was compared before operation and at 6 months after operation. The American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS) score were used to evaluate the functional recovery and pain relief of the patients before operation and at 6 and 24 months after operation. According to the severity of hallux rigidus, the patients were divided into mild group (Ⅰ, Ⅱ degree) and moderate group (Ⅲ degree) to compare the prognosis, including the changes of AOFAS score, VAS score, and the first metatarsophalangeal joint space. Results The operation time was 60-75 minutes (mean, 65 minutes). The intraoperative blood loss was 10-30 mL (mean, 20 mL). Two cases had superficial infection of the incision margin after operation, and healed well after dressing change and antibiotic treatment. The incisions of the other patients healed by first intention, and no medial cutaneous nerve injury of the great toe occurred. All patients were followed up 24-31 months, with an average of 25.8 months. The patient’s hallux valgus deformity was corrected without recurrence; no complication such as osteomyelitis and hallux varus occurred. The AOFAS score, VAS score, and the first metatarsophalangeal joint space after operation significantly improved when compared with those before operation, the AOFAS score and VAS score at 24 months after operation further improved when compared with those at 6 months after operation, and the differences were significant (P<0.05). The change of VAS score in mild group was significantly better than that in moderate group (P<0.05); but there was no significant difference in the changes of AOFAS score and the first metatarsophalangeal joint space between the two groups (P>0.05). ConclusionYoungswick-Akin osteotomy for moderate valgus deformity with mild to moderate hallux rigidus can achieve good functional recovery, pain relief, and joint space improvement.
Objective To explore the clinical value of shear wave elastography in the evaluation of quadriceps femoris lesions in patients with chronic obstructive pulmonary disease (COPD). Methods Fifty-eight COPD patients who were admitted to Chengdu First People’s Hospital and 55 healthy controls were included in the study between August 2021 and February 2022. The thickness, circumference, cross-sectional area and Young's modulus of quadriceps femoris in all subjects were measured using shear wave elastography combined with conventional two-dimensional ultrasound. The differences in ultrasound parameters between the two groups were compared, and the correlation between each ultrasound parameter and clinical evaluation indicators (modified British Medical Research Council Scale, COPD Assessment Test, six-minute walk test, and five-time sit-to-stand test) was analyzed. Results Young’s modulus values of the quadriceps femoris muscle were smaller in the COPD group than those in the healthy control group [COPD Group: rectus femoris 6.72 (6.22, 7.36) kPa, vastus medialis 6.25 (5.82, 6.79) kPa, vastus lateralis 6.94 (6.17, 7.48) kPa; healthy control group: rectus femoris 11.40 (10.23, 12.11) kPa, vastus medialis 10.77 (9.62, 11.42) kPa, vastus lateralis 11.14 (10.42, 12.52) kPa]. The differences were statistically significant (all P<0.05). The Young's modulus value of the rectus femoris muscle correlates with the aforementioned clinical evaluation indicators, with positive correlation with six-minute walk distance and negative correlation with COPD Assessment Test, modified British Medical Research Council Scale, five-time sit-to-stand time (P<0.05). Quadriceps thickness, circumference, and cross-sectional area measured by conventional two-dimensional ultrasound were not significantly different between the two groups, nor were there significant correlations between each parameter and clinical parameters (P>0.05). In addition, shear wave elastography has good reproducibility in the measurement of Young's modulus in quadriceps. Conclusions Shear wave elastography can identify quadriceps lesions earlier than conventional two-dimensional ultrasound in COPD patients, and there is a significant correlation between its measurements and the clinical condition of COPD patients. Shear wave elastography may provide a simple and noninvasive method for clinical evaluation of quadriceps femoris lesions in COPD patients.
ObjectiveTo explore the clinical features and prognosis of ischemic cerebral infarction in young population,and to provide a reference for clinical prevention of cerebral infarction in young population. MethodsA total of 547 patients with ischemic cerebral infarction diagnosed between January 2008 and June 2013 were included,and the difference in clinical data and outcomes between young and old patients were retrospectively compared. ResultsThe 547 patients included 233 young and 314 old patients,and there were more male patients in young group.As compared to the old group,the proportion of hypertension was significantly lower in young group (51.9%,64.3%;P=0.004);while smoking (51.9%,5.7%;P=0.000) and alcoholism (53.2%,28.3%;P=0.000) were significantly higher in young group.Moreover,there were more patients with vascular malformations in young group than that in old group (7.3%,3.2%;P=0.028).And there were also more patients in young group received thrombolytic therapy and antiplatelet therapy (98.3%,86.9;P=0.000),and the prognosis of young patients was significantly better than that of old patients. ConclusionThe prognosis of young patients with ischemic stroke prognosis is relatively good,and changing bad habits would be an effective measure to prevent and reduce the occurrence of ischemic cerebral infarction in young population.
Objective To study the application effect of Snyder hope theory combined with Satir model in the rehabilitation therapy of young and middle-aged patients with stroke. Methods A total of 224 young and middle-aged patients with stroke admitted to Zhongshan Hospital of Fudan University between August 2018 and August 2020 were divided into four groups (control group, Satir group, Snyder group, and combined group) according to the random number table method by taking admission time as sequence. All patients were given rehabilitation training on the basis of conventional treatment, and the Satir group was given group guidance of Satir model, the Snyder group was given hope therapy based on Snyder hope theory, and the combined group was given intervention combined Snyder hope theory with Satir model. All patients were continuously treated for six weeks. The scores of Herth Hope Index (HHI), Self-perceived Burden Scale (SPBS), exercise rehabilitation willingness questionnaire, Health Promoting Lifestyle Profile Ⅱ (HPLP Ⅱ), and Simplified Coping Style Questionnaire (SCSQ) were compared among the four groups before and after intervention. Results There were 53, 52, 54, and 52 patients enrolled in the control group, the Satir group, the Snyder group, and the combined group, respectively. The differences among the four groups in basic information such as sex, age, and type of stroke and the scores of the above scales before intervention were not statistically significant (P>0.05). After intervention, the total scores of HHI scale (27.65±6.34, 30.54±6.85, 32.79±7.12, 35.08±7.63), scores of exercise rehabilitation willingness (39.85±8.16, 40.52±7.93, 40.17±8.25, 43.81±7.46), total scores of HPLP Ⅱ scale (149.87±26.08, 159.32±26.73, 165.89±28.01, 173.18±28.54), and scores of positive coping style of SCSQ scale (19.65±5.08, 22.46±5.29, 25.04±4.91, 28.45±5.12) of the four groups significantly increased compared with those before intervention (P<0.05), while the total scores of SPBS scale (27.35±4.92, 23.74±5.02, 25.16±4.98, 21.49±5.27) and scores of negative coping style of SCSQ scale (4.83±1.25, 3.71±1.02, 3.94±1.08, 4.13±0.96) significantly decreased compared with those before intervention (P<0.05); the scores of HHI scale, exercise rehabilitation willingness, HPLP Ⅱ scale, and positive coping style of SCSQ scale of the combined group were higher than those of the other three groups (P<0.05), while the score of SPBS scale was lower than that of the other three groups (P<0.05). Conclusions Snyder hope theory combined with Satir model for rehabilitation therapy of young and middle-aged patients with stroke can help to improve the hope level, reduce the self-perceived burden, and improve the exercise rehabilitation willingness, health behaviors and coping styles. In addition, it is of great significance for promoting the rehabilitation of patients.
Abstract： Objective To investigate the effect of intramyocardial injection of slow release microspheres of tannic acid （TA） on ventricular remodeling after acute myocardial infarction （AMI） in rats. Methods Slow release microspheres of TA were prepared and the release parameters in vitro were detected. AMI model in rats was induced. Eighty rats were enrolled and divided into 4 groups by random digital table：poly （lactic-co-glycolic acid） （PLGA） microspheres injection （PLGA group， n=24）， PLGA-TA microspheres injection （PLGA-TA group， n=24）， TA injection group （TA group， n=16） and normal saline injection group （NS group， n=16）. Heart function was evaluated by echocardiography after the injection. The structure of cardiac extracellular matrix （ECM） in the infarcted borderline area was evaluated at 4th week after the injection. Collagen content in the infarcted area was evaluated by hydroxyproline colorimetry assay at 2nd and 4th week after the injection. Results TA release was maintained at a constant rate from the microspheres for one month in vitro. Two weeks after the injection， left ventricular ejection fraction（LVEF）， left ventricular fraction shortening（LVFS）， left ventricular end-diastolic diameter（LVEDD） and left ventricular end-systolic diameter（LVESD） in PLGA-TA group and TA group were significantly better than those in the other two groups（P＜0.05）. Four weeks after the injection， LVEF， LVFS， LVEDD and LVESD in PLGA-TA group were significantly better than those in the other three groups （P＜0.05）. Four weeks after the injection， slow release microspheres of TA in the PLGA-TA group effectively improved the arrangement of ECM compared with TA group. Four weeks after the injection， collagen content in the infarcted area of PLGA-TA group was significantly higher than that in TA group（88.88±7.28 μg/mg dry weight vs. 72.43±9.02 μg/mg dry weight）， PLGA group（88.88±7.28 μg/mg drg weight vs. 71.97±6.06 μg/mg dry weight） and NS group（88.88±7.28 μg/mg dry weight vs. 68.86±7.55 μg/mg dry weight， F=7.162，P=0.003）， but there was no statistical difference in the collagen content of the infarcted area among TA group， PLGA group and NS group （P＞0.05） . Conclusion Intramyocardial injection of slow release microspheres of TA can maintain a constant release of TA for a comparatively long period， inhibit collagen matrix degradation， and effectively attenuate ventricular remodeling after AMI in rats.
Objective To evaluate the therapeutic outcome of artificial total hip arthroplasty (THA) with collum femoris preserving for hip joint desease in young and middle-aged patients. Methods From March 2002 to March 2005, 26 cases (31 hips) of hip joint disease were treated with artificial THA with collum femoris preserving, including 19 males (23 hips)and 7 females (8 hips) and aged 32-48 years with an average of 37 years. In 31 hips, 17 left hips and 14 right hips were involved. There were 9 cases of osteoarthritis of the hip joint caused by avascular necrosis of the femoral head (ANFH), 7 cases of ANFH, 3 cases of femoral head necrosis caused by dysplasia of acetabular, 1 case of osteoarthritis of the hip joint caused by ankylosing spondyl itis, and 2 cases of rheumatoid arthritis; the course of disease was 2-11 years (5.6 years on average). Two cases of femoral neck fracture (Garden IV), and 2 cases of non-union femoral neck fractures (1 for Garden III and 1 for Garden IV), the course of disease was 5 days, 24 months, and 26 months. The prime symptoms were pain, difficult walk and l imp. All patients were taken X-ray to exclude osteoporosis. Results The right distal femur prosthesis of a bilateral patient cracked owing to excessive amputation of collum femoris, and fracture healed after symptomatic treatment. All the incisions healed by first intention and no compl ications occurred. All patients were followed up for 4-7 years, with an average of 5.6 years. One case had poor hip function because he did not follow rehabil itation procedure, and the others achieved good outcome with normal gait. One case complained of persistent pain 6 months after operation, and was rel ieved by administration of some non-steroidal antiinflammatory drugs and anti-osteoporosis drugs 6 months later. The X-ray films after operation and at last follow up showed good location of prosthesis and no bone resorption. Harris score at last follow-up was 91.31 ± 0.77, and it was significantly higher than that before operation (50.88 ± 0.90), (P lt; 0.05). The excellent and good rate was 93.5% (excellent in 11 hips, good in 18 hips, and fair in 2 hips). Conclusion Artificial THA with collum femoris preserving can retain more bone, be easier for revision, and has an excellent outcome.
Objective To review and summarize the surgical techniques and their outcomes for the treatment of lumbar spondylolysis in young patients by direct surgical repair. Methods Both home and abroad literature on the surgical techniques and their outcomes respectively for the treatment of lumbar spondylolysis in young patients by direct surgical repair was reviewed extensively and summarized. Results Direct surgical repair of lumbar spondylolysis can offer a simple reduction and fixation for the injured vertebra, which is also in accord with normal anatomy and physiology. In this way, normal anatomy of vertebra can be sustained. As reported surgical techniques of direct repair, such as single lag screw, hook screw, cerclage wire, pedicle screw cable, pedicle screw rod, and pedicle screw hook system, they all can provide acceptable results for lumbar spondylolysis in young patients. Furthermore, to comply strictly with the inclusion criteria of surgical management and select the appropriate internal fixation can also contribute to a good effectiveness. Within the various methods of internal fixation, pedicle screw hook system has been widely recognized. Conclusion Pedicle screw hook system fixation is simple and safe clinically. With the gradual improvement of this method and the development of minimally invasive technologies, it will have broad application prospects.
ObjectiveTo systematically evaluate the correlation between interpersonal stress and suicidal ideation. MethodsThe PubMed, EMbase, Cochrane Library, CBM, WanFang Data and CNKI databases were searched to collect studies on the correlation between interpersonal pressure and suicidal ideation from database inception to April 27, 2022. Two researchers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed using Stata 14.0 software. ResultsA total of 42 studies including 3 cohort studies, and 39 cross-sectional studies, with a total sample size of 193 810 participants were included. Meta-analysis showed that the risk of suicidal ideation was higher in people who had experienced interpersonal pressure than in people who had not (OR=2.11, 95%CI 1.99 to 2.23, P<0.01). Subgroup analysis showed that people in the Americas who had experienced interpersonal pressure were more strongly associated with suicidal ideation than people in other regions of the studied area. Young adults in the study who had experienced interpersonal pressure were more strongly associated with suicidal ideation than other studied age groups; People who had experienced partner pressure were more strongly associated with suicidal ideation than those who had experienced other types of interpersonal pressure. ConclusionThis study shows that people who have experienced interpersonal pressure are at greater risk of suicidal ideation, and there are certain differences among study areas, subjects and types of interpersonal pressure. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo systematically evaluate the association between MTHFR gene C677T polymorphism and susceptibility to young and middle-aged adult ischemic stroke among Chinese population. MethodsSuch databases as PubMed, EMbase, The Cochrane Library (Issue 11, 2013), CBM, CNKI, VIP and WanFang Data were systemically searched to collect case-control studies published from Jan 1990 to Dec 2013. RevMan 5.2 was used to quantitatively analyzed the qualified and included studies, the pooled odds ratio (ORs) with 95% confidence interval (CI) were calculated; Stata 12.0 software were used for sensitivity and publication bias analysis. ResultsA total of 10 studies were included, which involved 787 cases and 766 controls. The results of meta-analysis showed that, in overall young and middle-aged adult group (aged less than 60), individuals that carried T allele risked more with ischemic stroke than those carried C allele (OR=1.42, 95%CI 1.07 to 1.89, P=0.02); more susceptibility to ischemic stroke was found among people of TT genotype compared with those of CC genotype (OR=2.11, 95%CI 1.58 to 2.81, P=0.00), as well as those of TT+TC genotype compared with CC genotype (OR=1.97, 95%CI 1.55 to 2.51, P=0.00), and those of TT genotype compared with TC+CC genotype (OR=1.42, 95%CI 1.13 to 1.77, P=0.00). Increased risk was also observed in TT+TC genotype compared with CC genotype in young adult subgroup (aged less than 45) (OR=1.66, 95%CI 1.19 to 2.32, P=0.00). ConclusionMTHFR gene C677T polymorphism is significantly associated with susceptibility to young and middle-aged adult ischemic stroke among Chinese population, and more risk may exist in middle-aged adult population.
ObjectiveTo investigate and analyze the effectiveness of internal fixation with the two different cannulated screw implanting methods of rhomboid and inverted triangle in the treatment of femoral neck fracture in young adults.MethodsThe clinical data of 38 young adults with femoral neck fracture who met the selection criteria between January 2018 and August 2019 were retrospectively analyzed. According to the different methods of cannulated screw implanting, the patients were divided into two groups, 19 cases in each group. The trial group was treated with closed reduction and cannulated screw rhombic distribution internal fixation, while the control group was treated with closed reduction and cannulated screw inverted triangular distribution internal fixation. There was no significant differences in patients’ gender, age, cause of injury, Garden classification of fracture, and time from injury to operation between the two groups (P>0.05). The fracture healing time, the incidence of nonunion, femoral neck shortening, and femoral head necrosis were recorded and compared between the two groups; the effectiveness was evaluated by Harris score and visual analogue scale (VAS) score at last follow-up.ResultsThe incisions of the two groups healed by first intention. All patients were followed up 12-24 months with an average of 15.5 months. There were 1 case of fracture nonunion and 2 cases of shortening of femoral neck in the trial group; while there were 2 cases of fracture nonunion, 1 case of necrosis of femoral head, and 6 cases of femoral neck shortening in the control group; the difference in the incidence of complications (15.8% vs. 47.4%) between the two groups was significant (χ2=4.385, P=0.036). The remaining 18 cases in the trial group and 17 cases in the control group all achieved osteonal union, and the healing time was (14.8±1.6) weeks and (15.9±1.3) weeks, respectively, showing no significant difference between the two groups (t=1.265, P=0.214). At last follow-up, Harris score and VAS score of the trial group were 88.9±4.3 and 1.1±0.7, respectively, while those of the control group were 86.9±5.9 and 1.3±0.9, respectively, showing no significant difference (t=0.603, P=0.550; t=1.152, P=0.257). Hip function was evaluated in accordance with Harris score, the results were excellent in 12 cases, good in 6 cases, and fair in 1 case in the trial group, the excellent and good rate was 94.74%; the results were excellent in 10 cases, good in 7 cases, and fair in 2 cases in the control group, the excellent and good rate was 89.47%; there was no significant difference in the excellent and good rate between the two groups (χ2=0.368, P=0.544).ConclusionThe short-term effectiveness of the two kinds of cannulated screw implanting methods is clear, rhomboid fixation of 4 screws has strong stability with stress distribution, which can effectively reduce the incidence of femoral neck shortening, fracture nonunion, femoral head necrosis, and other complications.
