ABSTRACT

{L-End}Objective To explore the status of quality control assessment of pure tone audiometry (PTA) and to analyze its influencing factors in occupational medical examination (OME) institutions in Guangzhou City. {L-End}Methods A total of 41 OME institutions in Guangzhou City were selected as the research subjects from 2021 to 2022 using random sampling method, and its status of on-site quality and PTA quality for individuals exposed to noise were assessed. {L-End}Results A total of 205 rectification items were identified among the 41 OME institutions from 2021 to 2022. Among them, 19, 28, 30, and 28 OME institutions did not meet the requirements of organizational structure, quality management system, quality control of OME, and health examination information reporting, respectively. A total of 1 095 OME reports for individuals exposed to noise were assessed, with 820 reports having correct results and conclusions, resulting in an accuracy rate of 74.9%. The results of the multiple logistic regression analysis showed that OME institutions without meeting the requirements for the quality management system had a higher risk of failing the PTA quality control assessment and having inaccurate hearing test results compared with those meeting the requirements (all P<0.05). OME institutions with a filing period less than one year had a higher risk of having inaccurate hearing test results than those with a filing period of one year or more (P<0.05). OME institutions not meeting the requirements for quality control of OME had a higher risk of having abnormal OME conclusions than those meeting the requirements (P<0.05). OME institutions not meeting the requirements for health examination information reporting had a higher risk of having abnormal conclusions in suspected occupational disease than those meeting the requirements (P<0.05). OME institutions not meeting the requirements for the quality management system had a higher risk of having abnormal conclusions of occupational contraindications than those meeting the requirements (P<0.05). {L-End}Conclusion The quality of PTA in OME institutions in Guangzhou City needs to be improved. And a well-established quality management system for OME is beneficial for improving the quality of PTA.

ABSTRACT

{L-End}Objective To investigate the current status of long working hours of food-delivery workers from food-delivery platform, and analyze its impact on their health such as occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and life satisfaction. {L-End}Methods A total of 2 145 food-delivery workers from two food-delivery platforms in Guangzhou City were selected as the research subjects using convenience sampling method. The occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and life satisfaction were investigated using the Core Occupational Stress Scale, Patient Health Questionnaire-9 items, Self-sleep Management Questionnaire, Self-diagnosis Questionnaire of Fatigue Accumulation of Workers, and World Health Organization Five-item Well Being Index. {L-End}Results The median and the 25th and 75th percentiles of weekly working hours were 63 (49,77) hours. And 92.2% (1 978/2 145) of workers, who worked more than 40 hours per week, were long working hours workers. While 70.1% (1 504/2 145) workers, who worked 55 hours or more per week, were ultra-long working hours workers. The detection rate of occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and low life satisfaction was 30.1%, 27.5%, 34.7%, 40.8%, and 75.1%, respectively. The longer the weekly working hours of the research subjects, the higher the detection rate of occupational stress and fatigue accumulation (all P<0.01). The results of multivariate logistic regression analysis showed that ultra-long working hours (weekly working hours ≥55 hours) was the influencing factor of occupational stress and fatigue accumulation after excluding the influence of confounding factors among workers (all P<0.05). {L-End}Conclusion The food-delivery workers of food-delivery platforms generally work long hours. Ultra-long working hours is a risk factor for occupational stress and fatigue accumulation among these workers.

ABSTRACT

{L-End}Objective To investigate the current status and influencing factors of leg work-related musculoskeletal disorders (WMSDs) in shipbuilding workers. {L-End}Methods A total of 3 393 shipbuilding workers from Guangdong Province, Liaoning Province, Shandong Province, and Beijing City were selected as the research subjects using the convenience sampling method. The Chinese Version of the Musculoskeletal Disorders Questionnaire was used to investigate the prevalence of leg WMSDs in the past year. A multivariate logistic regression model was used to analyze the influencing factors of leg WMSDs. {L-End}Results The prevalence of leg WMSDs in the research subjects was 11.3% (382/3 393). The result of multivariate logistic regression showed that the risk of leg WMSDs was higher in workers with a length of service >10 years than those with a length of service <5 years (P<0.05). Workers with frequent used of vibration tools at work had higher the risk of leg WMSDs (all P<0.05). Workers who did the same work every day, had insufficient rest time, had a shortage of department staff, and those who often repeated the same leg movements had a higher risk of leg WMSDs (all P<0.05). The risk of leg WMSDs in workers who sometimes stand for a long time was lower than that in workers who rarely stand for a long time (P<0.01). {L-End}Conclusion Length of service, rarely long-standing work, use of vibration tools at work, daily engagement in the same work, in-adequate rest time, shortage of department staff, and frequent repetition of the same leg movements are all influencing factors for leg WMSDs in shipbuilding workers.

ABSTRACT

{L-End}Objective To analyze the local muscle response under continuous ergonomic workload by simulating manual lifting, and to screen the sensitive metabolic biomarkers during fatigue process. {L-End}Methods A total of 13 healthy male volunteers were selected as the study subjects using simple random sampling method. Study subjects underwent repetitive simulated manual lifting for four periods (T1 to T4), each lasting 12 minutes. The degree of work-related fatigue in the forearm, upper arm, shoulder, back, and leg muscles, and the whole body was accessed using Borg 6-20 Rating of Perceived Exertion (RPE) Scale. The venous blood samples were collected from elbow between each two periods to detect the levels of eight metabolic biomarkers: ammonia, lactate, creatine kinase, lactate dehydrogenase (LDH), C-terminal telopeptide of type Ⅰ collagen (CTX-Ⅰ), C-terminal telopeptide of type Ⅱ collagen (CTX-Ⅱ), cartilage oligomeric matrix protein (COMP), and calcium ions. {L-End}Results The RPE scores of the study subjects for the muscles of five body parts and the whole body increased with the increasing lifting periods (all P<0.01). Fatigue was observed in all target muscles, with overall body fatigue occurring in the T2 period. The levels of ammonia, lactate, creatine kinase, LDH, COMP, and calcium ions in the serum of study subjects were higher in the T1 to T4 periods than in the T0 period (all P<0.05). The serum CTX-Ⅰ level was higher in the T1 and T3 periods than that in the T0 period (all P<0.05) , and the serum CTX-Ⅱ level was higher in the T1, T2 and T4 periods than that in the T0 period (all P<0.05). The level of these eight serum metabolic biomarkers fluctuated during the T1 to T4 periods. The serum creatine kinase level increased with the period of lifting (all P<0.05). The serum lactate level was higher in the T3 period than those in the T1 and T2 periods (all P<0.05). The serum LDH and calcium ion levels were higher in the T2 to T4 periods than that in the T1 period (all P<0.05). The serum COMP level was higher in the T2 and T3 periods than that in the T1 period (all P<0.05). Except for CTX-Ⅰ, the levels of other seven metabolic markers in serum were higher in individuals after fatigue than before fatigue (all P<0.05). {L-End}Conclusion Serum metabolic biomarkers such as ammonia, lactate, creatine kinase, calcium ions, LDH, CTX-Ⅱ, and COMP exhibit significant changes before and after fatigue. These metabolic biomarkers could be used as sensitive biomarkers for evaluating muscle fatigue during repetitive works.

ABSTRACT

{L-End}Objective To analyze the prevalence of multi-site work-related musculoskeletal disorders (WMSDs) and their influencing factors among workers in the chemical pharmaceutical industry. {L-End}Methods A total of 563 workers from three chemical pharmaceutical factories in Guangzhou City were selected as the research subjects using the judgment sampling method. The prevalence of multi-site WMSDs in the past 12 months was investigated using the electronic questionnaire of Chinese Version of Musculoskeletal Disorders Questionnaire. {L-End}Results The prevalence of multi-site WMSDs in the research subjects was 30.0% (169/563). The results of multivariable logistic regression analysis showed that workers who smoked regularly/frequently and those who had their hands above shoulder level for long periods of time had a lower risk of multi-site WMSDs than those who never/occasionally smoked (all P≤0.05). Workers with a high school, secondary specialty, college degree, or above had a lower risk of multi-site WMSDs than those with a middle school education or below (all P<0.05). The longer the daily working hours, the higher the risk of multiple WMSDs (all P<0.05). Workers with regular/frequently work shifts had a lower risk of multi-site WMSDs than those with none/occasional work shifts (P<0.05). {L-End}Conclusion The prevalence of multi-site WMSDs among workers in the chemical pharmaceutical industry is relatively high. The influencing factors are individual factors, unreasonable work organization and poor ergonomics factors.

ABSTRACT

Methods@#Data analysis was carried out to identify the variables that had a significant impact on survival. For all patients with spinal metastasis from lung cancer who received non-surgical treatment, the Tomita score, revised Tokuhashi score, modified Bauer score, Van der Linden score, classic SORG algorithm, SORG nomogram, and NESMS were calculated. The performance of the scoring systems was assessed by using receiver operating characteristic (ROC) curves at 3 months, 6 months, and 12 months. The predictive accuracy of the scoring systems was quantified using the area under the ROC curve (AUC). @*Results@#A total of 127 patients are included in the present study. The median survival of the population study was 5.3 months (95% confidence interval [CI], 3.7–9.6 months). Low hemoglobin was associated with shorter survival (hazard ratio [HR], 1.49; 95% CI, 1.00–2.23; p =0.049), while targeted therapy after spinal metastasis was associated with longer survival (HR, 0.34; 95% CI, 0.21–0.51; p <0.001). In the multivariate analysis, targeted therapy was independently associated with longer survival (HR, 0.3; 95% CI, 0.17–0.5; p <0.001). The AUC of the time-dependent ROC curves for the above prognostic scores revealed all of them performed poorly (AUC <0.7). @*Conclusions@#The seven scoring systems investigated are ineffective at predicting survival in patients with spinal metastasis from lung cancer who are treated non-surgically.

ABSTRACT

The in vitro transcribed (IVT) mRNA technology has progressed rapidly and the application of mRNA vaccines in the COVID-19 pandemic made it become the most talked-about topic. Compared with protein drugs, IVT mRNA has a lower cost; it can be modular produced and its sequence can be modified easily, so it has a broad application prospect. However, due to its short history, mRNA drugs face the problem of lacking sufficient clinical data, and there is no quality control standard for mRNA drugs except mRNA vaccines. We overview the sequence design, delivery vectors, administration, application prospect and safety considerations of mRNA drugs. We also discussed the quality control of mRNA drugs briefly.

ABSTRACT

Krüppel-like transcription factor 2 (KLF2) plays a key regulatory role in endothelial inflammation, thrombosis, angiogenesis and macrophage inflammation and polarization, and up-regulation of KLF2 expression has the potential to prevent and treatment atherosclerosis. In this study, trichostatin C (TSC) was obtained from the secondary metabolites of rice fermentation of Streptomyces sp. CPCC 203909 as a KLF2 up-regulator by using a high throughput screening model based on a KLF2 promoter luciferase reporter assay. TSC significantly inhibited the adhesion of tumor necrosis factor-α (TNFα) induced monocytes (THP-1) to human umbilical vein endothelial cells (HUVECs). Western blot results showed that TSC decreased TNFα induced the protein expression increase of vascular cell adhesion molecule-1 (VCAM-1), and thereby inhibited endothelial inflammation. The results of histone deacetylase (HDAC) overexpression and molecular docking experiments showed that TSC upregulated the expression of KLF2 by inhibiting subtypes of HDAC 4/5/7. In conclusion, this study suggests that TSC up-regulates the expression of KLF2 through inhibiting HDAC 4/5/7 and thus inhibits TNFα induced endothelial inflammation, and it has the potential to prevent and treat atherosclerosis.

ABSTRACT

The AP2/ERF gene family is one of the largest transcription factor families in the plant kingdom, and plays an important role in response to biological and abiotic stresses, plant hormone responses, and plant growth and development. In this study, the AP2/ERF family of Panax notoginseng was identified by bioinformatics methods, and the physicochemical properties, structure, phylogenetic relationship, expression pattern and function of PnDREB4 gene of the family were analyzed. The results showed that 140 AP2/ERF family members were identified in P. notoginseng, which were divided into DREB, ERF, AP2, RAV and Sololit subgroups. The physicochemical properties and motifs of proteins were similar among the subgroups. There were 34 differentially expressed genes in the AP2/ERF family of Fusarium oxysporum infected P. notoginseng plants, and 19 genes were up-regulated. The expression level of PnDREB84 was up-regulated with the extension of Fusarium oxysporum infection time in the range of 0-96 h. The content of ABA and SA in P. notoginseng plants overexpressing PnDREB84 gene increased after 4 ℃ stress. The results showed that PnDREB84 gene plays a dual regulatory role in the process of biological stress and abiotic stress. PnDREB84 gene can be used as a potential molecular marker for the breeding of new varieties of P. notoginseng. The identification of AP2/ERF transcription factor and function analysis of PnDREB84 gene of P. notoginseng provided data support for the analysis of stress resistance mechanism of P. notoginseng and the breeding of new varieties.

ABSTRACT

Phosphodiesterase 4 (PDE4) is an important member of the phosphodiesterase enzyme family that specifically catalyzes the hydrolysis of cyclic adenosine monophosphate (cAMP), activates the downstream phosphorylation cascade pathway by altering cAMP concentration, and is strongly associated with multiple diseases. Inhibition of PDE4 is clinically investigated as a therapeutic strategy in a broad range of disease areas, including respiratory system diseases, autoimmune disorders, central nervous system diseases, and dermatological conditions. However, the incidence of adverse reactions such as nausea and vomiting is relatively high in the marketed PDE4 inhibitors, which has stalled their clinical development. In this review, we provide an overview of the clinical progression and safety issues of the marketed PDE4 inhibitors. We also review the main causes underlying PDE4-mediated adverse effects by combining the structural analysis of the PDE4 protein, the mechanism of action of PDE4 inhibitors, and the related side effect mechanism research, aiming to provide a reference for the development of safe and effective PDE4 inhibitors.

ABSTRACT

@#Objective     To investigate the influencing factors for the clinical remission of advanced esophageal squamous cell carcinoma (ESCC) after neoadjuvant chemotherapy, establish an individualized nomogram model to predict the clinical remission of advanced ESCC with neoadjuvant chemotherapy and evaluate its efficacy, providing serve for the preoperative adjuvant treatment of ESCC. Methods     The clinical data of patients with esophageal cancer who underwent neoadjuvant chemotherapy (nedaplatin 80 mg/m2, day 3+docetaxel 75 mg/m2, day 1, 2 cycles, 21 days per cycle interval) in the Department of Thoracic Surgery, Affiliated Hospital of North Sichuan Medical College from February 2016 to August 2020 were analyzed retrospectively. According to the WHO criteria for efficacy assessment of solid tumors, tumors were divided into complete remission (CR), partial remission (PR), stable disease (SD) and progressive disease (PD). CR and PR were defined as effective neoadjuvant chemotherapy, and SD and PD were defined as ineffective neoadjuvant chemotherapy. Univariate and multivariate analyses were used to analyze the influencing factors for the short-term efficacy of neoadjuvant chemotherapy. The R software was used to establish a nomogram model for predicting of the model. C-index, calibration curve and receiver operating characteristic (ROC) curve were used to evaluate the predictive performance of the nomogram. Results     Finally 115 patients were enrolled, including 93 males and 22 females, aged 40-75 (64.0±8.0) years. After receiving docetaxel+nedaplatin neoadjuvant chemotherapy for 2 cycles, there were 9 patients with CR, 56 patients with PR, 43 patients with SD and 7 patients with PD. Among them, chemotherapy was effective (CR+PR) in 65 patients and ineffective (SD+PD) in 50 patients, with the clinical effective rate of about 56.5%(65/115). Univariate analysis showed that there were statistical differences in smoking history, alcoholism history, tumor location, tumor differentiation degree, and cN stage before chemotherapy between the effective neoadjuvant chemotherapy group and the ineffective neoadjuvant chemotherapy group (P<0.05). Logistic regression analysis showed that low-differentiation advanced ESCC had the worst clinical response to neoadjuvant chemotherapy, moderately-highly differentiated ESCC responded better (P<0.05). Stage cN0 advanced ESCC responded better to neoadjuvant chemotherapy than stage cN1 and cN2 (P<0.05). The C-index and the area under the ROC curve of the nomogram were both 0.763 (95%CI 0.676-0.850), the calibration curve fit well, the best critical value of the nomogram calculated by the Youden index was 70.04 points, and the sensitivity and specificity of the critical value were 80.0% and 58.0%, respectively. Conclusion    The established clinical prediction model has good discrimination and accuracy, and can provide a reference for individualized analysis of the clinical remission of advanced ESCC with neoadjuvant chemotherapy and the screening of new adjuvant treatment subjects.

ABSTRACT

Objective:To observe any effect of threshold pressure loaded inspiratory muscle training on the balance of persons with Parkinson′s disease (PD).Methods:Forty-eight persons with PD were randomly divided into an observation group and a control group, each of 24. Both groups were given conventional neurological drug treatment and conventional rehabilitation training. The observation group additionally completed inspiratory muscle training using a threshold pressure load trainer, 5 days per week for 8 weeks. Before and after the treatment, both groups′ inspiratory muscle functioning was quantified using ultrasound to assess diaphragm mobility and thickness, and maximum inspiratory pressure (MIP). Balance was quantified using Trunk Injury Scale (TIS) scoring, the Berg Balance Scale (BBS), limits of stability (LOS), and the timed up and go test (TUGT). Walking was evaluated using the 10-metre walk test (10MWT) and the Dynamic Gait Index (DGI).Results:After the treatment all of the indicators had improved significantly in both groups, on average, but those of the observation group were then significantly better. Correlation analysis showed that the difference in MIP of the observation group before and after treatment was significantly negatively correlated with the TUGT and 10MWT times.Conclusion:Threshold pressure loaded inspiratory muscle training combined with conventional rehabilitation therapy significantly improves the inspiratory muscle strength, balance and walking of persons with PD.

ABSTRACT

Objective:To investigate whether caffeic acid phenethyl ester (CAPE) would improve peritoneal dialysis (PD)-associated peritoneal fibrosis by alleviating oxidative stress through activating nuclear factor erythroid-2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway.Methods:Thirty-two male Sprague-Dawley rats were randomly divided into four groups by the random number table: control (CON) group (0.9% normal saline 20 ml/d intraperitoneal injection), CAPE group (0.9% normal saline 20 ml/d+CAPE 10 mg·kg -1·d -1 intraperitoneal injection), PD group [4.25% glucose peritoneal dialysis fluid (PDF) 20 ml/d intraperitoneal injection with lipopolysaccharide 0.6 mg/kg intraperitoneal injection at day 1, 3, 5 and 7], and PD+CAPE group (CAPE 10 mg·kg -1·d -1 intraperitoneal injection in addition to PD group), with 8 rats per group. On day 28, rats were euthanized after peritoneal equilibration test, and then the parietal peritoneum and omentum were collected for follow-up tests. To further investigate the mechanism, primary peritoneal mesothelial cells (PMCs) of rats were isolated and cultured. The PMCs were stimulated with 2.5% glucose PDF and added with 5 μmol/L CAPE intervention. The Nrf2 inhibitor (ML385) was used to identify whether CAPE protected PMCs from PDF by activating the Nrf2/HO-1 pathway. Histopathological staining was used to detect structural changes of the peritoneum, and immunohistochemical analysis was performed on cleaved caspase-3, Bax, α-smooth muscle actin (α-SMA), fibronectin (FN), and typeⅠ collagen (Col-Ⅰ) protein. Western blotting was used to detect the protein expression of α-SMA, FN, transforming growth factor-β1 (TGF-β1), HO-1 and nuclear Nrf2 (N-Nrf2). The apoptosis detection kit was used to detect apoptosis and flow cytometry was used to detect reactive oxygen species (ROS) in PMCs. The malondialdehyde (MDA) and superoxide dismutase (SOD) activity detection kit were used to detect MDA content and SOD activity. Cell immunofluorescence was used to analyze the protein expression of Nrf2 in PMCs. Results:Compared with the CON group, the PD group had thicker peritoneum, and the expression levels of cleaved caspase-3, Bax, α-SMA, FN, Col-Ⅰand MDA in peritoneum were significantly higher, while HO-1, N-Nrf2 protein expression and SOD activity were lower (all P<0.05). Compared with the PD group, the parietal peritoneum morphology of CAPE+PD group was improved, accompanied by reduced cleaved caspase-3, Bax, α-SMA, FN, Col-Ⅰ protein expression, and MDA content, while N-Nrf2, HO-1 protein expression, and SOD activity were higher (all P<0.05). Compared with the CON group, the PD group had significantly lower ultrafiltration volume and higher peritoneal permeability (both P<0.05). After CAPE intervention, the peritoneal transport function of the rats was significantly improved ( P<0.05). In cultured PMCs, PDF inhibited nuclear translocation of Nrf2 and protein expression of HO-1, and upregulated intracellular ROS level. In addition, PDF increased cell apoptosis and the protein expression levels of α-SMA, TGF-β1 and FN (all P<0.05). CAPE activated nuclear translocation of Nrf2, increased HO-1 protein expression, downregulated intracellular ROS level, and partially reversed PDF-induced cell apoptosis and epithelial- mesenchymal transition (all P<0.05). The protective effects of CAPE on PMCs were partially abolished by ML385 (all P<0.05). Conclusions:CAPE can reduce PD-induced PMCs apoptosis and epithelial-mesenchymal transition by attenuating oxidative stress, and significantly improve peritoneal fibrosis and ultrafiltration function. The beneficial effects of CAPE on peritoneum are related to activation of Nrf2/HO-1 pathway.

ABSTRACT

Objective:To explore the risk factors of overactive bladder(OAB)syndrome in older women with stress urinary incontinence(SUI).Methods:In this cross-sectional study, 157 elderly women with SUI, aged 60-88(65.6±5.4)years, were recruited from Qingshan District Maternal and Child Health Hospital and areas serviced by Fozuling Community Service Center in Wuhan between October to November 2020.Data collection included a questionnaire covering general information, dietary habits, childbirth history, medical history, the urogenital distress inventory(UDI-6)and the overactive bladder symptom score(OABSS), and physical examinations on curvature of the spine, pelvic floor muscle strength and pelvic floor ultrasound imaging.Results:A total of 157 elderly women with SUI were included in the study and the prevalence of OAB was 17.2%(27 cases). The prevalence of OAB was 17.6%(25 cases)among 142 patients with mild SUI and 13.3%(2 cases)among 15 patients with moderate or severe SUI, but SUI severity was not correlated with the prevalence of OAB( χ2=0.003, P>0.05). The UDI-6 score was 2.39±2.04 and the OABSS score was 3.70±2.48, with a positive correlation between OABSS and UDI-6( r=0.254, P<0.01), suggesting that OAB had a negative effect on the quality of life of patients with SUI.Multivariate Logistic regression analysis on factors with P<0.3 in the univariate analysis showed that number of pregnancies( P<0.01), anterior vaginal wall prolapse( P<0.05), and abnormal inclination of the pelvis( P=0.05)were associated with the prevalence of OAB.Regarding the number of pregnancies, the risk of OAB increased with 2-3 pregnancies( OR=1.46, 95% CI: 0.25-8.56)and with 3 pregnancies or more( OR=4.29, 95% CI: 0.79-23.18), compared with the prevalence at no more than 1 pregnancy.Compared with patients without anterior vaginal wall prolapse, Ⅰ-Ⅱ degree prolapse increased the risk of OAB( OR=4.21, 95% CI: 1.40-12.63), and third-degree prolapse further increased the risk( OR=11.48, 95% CI: 1.37-96.17). Compared with patients with normal inclination of the pelvis, anterior or posterior pelvis inclination promoted the occurrence of OAB( OR=3.46, 95% CI: 1.23-9.73; OR=2.62, 95% CI: 0.54-12.71). Conclusions:OAB has a negative impact on the quality of life of elderly women with SUI.Pregnancy, anterior vaginal prolapse and abnormal inclination of the pelvis promote the occurrence of OAB.

ABSTRACT

Objective:To compare the efficacies of arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement in the treatment of chronic lateral ankle instability (CLAI) concomitant with fibular tendinitis.Methods:A retrospective cohort analysis was conducted on the clinical data of 31 patients with CLAI concomitant with fibular tendinitis, who were treated in Beijing Tongren Hospital, Capital Medical University between March 2019 and December 2021. The patients included 17 males and 14 females, aged 16-57 years [(32.8±9.6)years]. The anterior drawer test and talar tilt test were positive in all patients preoperatively. Diagnosis was confirmed by physical examination and MRI, and calcaneofibular ligament rupture was excluded. Eleven patients received arthroscopic modified Brostr?m procedure combined with peroneal tendon debridement (modified Brostr?m procedure+tendon debridement group), and 20 underwent pure arthroscopic modified Brostr?m procedure (modified Brostr?m procedure group). The operation time, intraoperative blood loss and length of hospital stay were documented. The visual analogue score (VAS) in peroneal tendon area was assessed before operation and at postoperative 2, 6 and 12 weeks. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and foot and ankle outcome score (FAOS) were assessed before operation and at postoperative 6 and 12 weeks. The anterior drawer test was performed at the last follow-up. The foot and ankle ability measure (FAAM) score was assessed before operation and at the last follow-up. Postoperative wound healing and complications were also observed.Results:All the patients were followed up for 4-19 months [(11.3±3.5)months]. The operation time was (66.0±4.2)minutes in the modified Brostr?m procedure+tendon debridement group, which was significantly longer than (61.5±3.4)minutes in the modified Brostr?m procedure group ( P<0.05). There was no significant difference in intraoperative blood loss or length of hospital stay between the two groups (all P>0.05). Compared with the preoperation, the value of VAS was significantly lowered, and the values of AOFAS ankle-hindfoot score, FAOS and FAAM score were significantly increased at different postoperative timepoints (all P<0.01). No significant differences in the values of VAS, AOFAS ankle-hindfoot score, FAOS or FAAM score were seen between the two groups before operation (all P>0.05). The value of VAS was 3.0(3.0, 4.0) points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 4.0(4.0, 4.0)points in the modified Brostr?m procedure group at 2 weeks postoperatively ( P<0.05). The value of VAS was 2.0(1.0, 3.0)points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 3.0(2.3, 3.0)points in the modified Brostr?m procedure group at 6 weeks postoperatively ( P<0.05). At 12 weeks postoperatively, there was no significant difference in the value of VAS between the two groups ( P>0.05). There were no significant differences in the values of AOFAS ankle-hindfoot score and FAOS between the two groups at 6 or 12 weeks postoperatively (all P>0.05). The anterior drawer test was negative in all patients at the last follow-up. No significant difference was seen in the value of FAAM score between the two groups at the last follow-up ( P>0.05). All incisions were healed well in the first stage after operation, without the occurrence of joint infection, impaired joint motion, nerve injury or deep vein thrombosis. Conclusions:Arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement can both improve the foot function in CLAI patients concomitant with fibular tendinitis. However, the combined treatment allows for early pain relief, without increasing the risk of complications, and can therefore contribute to a faster postoperative recovery.

ABSTRACT

Objective:To investigate the association between preterm birth, low birth weight and the risk of hypospadias.Methods:According to the search strategy of Cochrance Collaborative Network, the China National Knowledge Internet (CNKI), VIP, Wanfang, Pubmed, Cochrance and Embase were searched from the establishment of the database to April 2022. The literature on the relationship between preterm birth, low birth weight and the risk of hypospadias was included. Meta analysis was conducted on the relationship between preterm birth, low birth weight and the risk of hypospadias.Results:A total of 13 articles were included, including cases from Asia, Europe, Australia and America. Newcastle-ottawa Scale was used for evaluation, and the scores were all above 6. There were 10 articles on the relationship between preterm birth and the risk of hypospadias, all of which were case-control studies. Heterogeneity test I2=46%, P=0.05. There were 3 521 cases in the case group and 95 816 cases in the control group. Compared with the control group, preterm birth was a risk factor for hypospadias ( OR: 2.13, 95% CI: 1.89-2.41), and the difference was statistically significant ( Z=12.21, P<0.01). There were 11 articles on the association between low birth weight and the risk of hypospadias, all of which were case-control studies. Heterogeneity test I2=47%, P=0.04. There were 2 460 cases in the case group and 94 260 cases in the control group. Compared with the control group, low birth weight was a risk factor for hypospadias ( OR: 3.29, 95% CI: 2.57-4.22), and the difference was statistically significant ( Z=9.40, P<0.01). Conclusions:Based on meta-analysis of published literature, preterm birth and low birth weight increase the risk of hypospadias.

ABSTRACT

Objective:To investigate the clinical efficacy of butylphthalide combined with hyperbaric oxygen therapy on post-stroke cognitive impairment in patients with acute ischemic stroke.Methods:A total of 90 patients with post-stroke cognitive impairment who were hospitalized within 72 hours of onset in Suining County People's Hospital from December 2019 to November 2020 were included in this study. They were randomly divided into a control group and an observation group ( n = 45/group). The control group was given conventional treatment and the observation group was given butylphthalide combined with hyperbaric oxygen therapy in addition to conventional treatment. The National Institutes of Health Stroke Scale score, Montreal Cognitive Assessment score, and Activities of Daily Living score were compared between the two groups before and after treatment. Results:Before treatment, there were no significant differences in the National Institutes of Health Stroke Scale score, Montreal Cognitive Assessment score, and Activities of Daily Living score between the two groups (all P > 0.05). At 14 days and 1 month after surgery, the National Institutes of Health Stroke Scale scores in the observation group were (4.02 ± 2.18) points and (3.21 ± 2.03) points, which were significantly lower than (5.21 ± 2.24) points and (4.62 ± 2.68) points in the control group ( t =2.55, 2.81, both P < 0.05). At 1 and 3 months after treatment, the Montreal Cognitive Assessment score in the observation group were (19.79 ± 5.67) points and (23.69 ± 2.67) points, which were significantly higher than (16.88 ± 5.12) points and (19.74 ± 2.29) points in the control group ( t = 2.56, 7.53, both P < 0.05). At 1 and 3 months after treatment, Activities of Daily Living scores in the observation group were (54.85 ± 5.69) points and (74.38 ± 4.98) points, which were significantly higher than (46.78 ± 6.24) points and (63.21 ± 5.24) points in the control group ( t = 6.41, 9.76, both P < 0.05). Conclusion:Butylphthalide combined with hyperbaric oxygen therapy for the treatment of post-stroke cognitive impairment in patients with acute ischemic stroke can alleviate neurologic deficits, and improve cognitive function and the ability of daily life.

ABSTRACT

Objective:To deeply explore the real work of primary, secondary and tertiary prevention of stroke in general hospitals, rehabilitation and pension institutions and community health service centers (stations), and to provide reference for improving the level of comprehensive prevention of stroke in the medical system.Methods:From July to November 2022, face-to-face semi-structured interviews with 18 medical staff in general hospitals, 10 medical staff in rehabilitation and pension institutions, and 8 medical staff in community health service centers (stations) were conducted by phenomenological research methods. Colaizzi 7-step analysis method was used to analyze the interview data, and Nvivo12 software was used to code the interview data.Results:Four themes were extracted: hospitals, institutions and communities all played an important role in the comprehensive prevention of stroke and actively cooperated with each other; the public was still lack of comprehensive prevention awareness and correct cognition of stroke; lack of professional medical resources hindered the development of comprehensive stroke prevention; incomplete collaborative mechanism of comprehensive prevention of stroke in hospitals, institutions and communities.Conclusions:In the current comprehensive prevention of stroke, there are still problems such as weak public awareness of prevention, insufficient professional medical resources, and imperfect coordination mechanism. In view of the advantages of medical institutions at all levels, it is necessary to clarify the responsibilities of the system at all levels and explore efficient and sustainable coordination mechanism, so as to improve the comprehensive prevention level of stroke in the medical system.
