OBJECTIVE: To 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). CONCLUSION Youngswick-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 investigate the effect of indigo on inflammatory factors and the aryl hydrocarbon receptor(AhR)/NOD-like receptor thermal protein domain associated protein 3(NLRP3)signaling pathway in lipopolysaccharide(LPS)-induced keratinocytes(HaCaT cells).Methods An LPS-induced HaCaT cell model was established,and experimental groups were set as follows:blank group,model group,indigo group,AhR agonist(2,3,7,8-tetrachlorodibenzo-p-dioxin,TCDD)group,AhR inhibitor(CH-223191)group,and indigo+AhR inhibitor group.The Cell Counting Kit-8(CCK-8)assay was used to detect the effects of different concentrations of indigo,TCDD,and CH-223191 on HaCaT cell viability after 24 hours of intervention.Quantitative real-time PCR(qPCR)was employed to measure the mRNA expression levels of interleukin-1β(IL-1β),nuclear factor kappa B(NF-κB),tumor necrosis factor-α(TNF-α),AhR,cytochrome P450 family 1 subfamily A member 1(CYP1A1),NLRP3,Caspase-1,and apoptosis-associated speck-like protein(ASC)in each group.Western Blot analysis was used to assess changes in the cellular localization of AhR protein expression.Results(1)The IC50 of indigo intervention in HaCaT cells was 118.7 μmol·L-1.Treatment with different concentrations of CH-223191 and TCDD for 24 hours had no significant effect on HaCaT cell viability.(2)Compared with the model group,the indigo group showed decreased mRNA expression levels of IL-1β,NF-κB,NLRP3,and Caspase-1(P＜0.05 or P＜0.000 1),while the mRNA expression levels of AhR and CYP1A1 were significantly increased(P＜0.05 or P＜0.000 1).(3)Compared with the blank group,the indigo group reduced cytoplasmic AhR protein expression and increased nuclear AhR protein expression(P＜0.001 or P＜0.000 1).(4)Compared with the model group,both the indigo group and the AhR agonist group significantly increased AhR mRNA expression levels(P＜0.05),while the AhR inhibitor group decreased AhR and CYP1A1 mRNA expression levels(P＜0.05)and increased IL-1β and NLRP3 mRNA expression levels(P＜0.05).(5)Compared with the AhR inhibitor group,the indigo+AhR inhibitor group showed increased mRNA expression levels of AhR and CYP1A1(P＜0.05)and decreased mRNA expression levels of NLRP3,Caspase-1,and IL-1β(P＜0.05).Conclusion Indigo reduces inflammatory factors in LPS-induced HaCaT cells and participates in inhibiting the occurrence and development of psoriasis by activating AhR to negatively regulate the NLRP3 inflammasome.

Objective To compare the effect of palliative mitral valve surgeries and medication therapies for secondary non-ischemic mitral regurgitation. Methods The clinical data of patients with non-ischemic functional mitral regurgitation treated in our hospital between 2009 and 2019 were retrospectively analyzed. Patients with a left ventricular ejection fraction (LVEF)＜40% underwent a dobutamine stress test, and a positive result was determined when the LVEF improved by more than 15% compared to the baseline value. Positive patients were divided into a surgery group and a medication group. The surgery group underwent surgical mitral valve repair or replacement, while the medication group received simple medication treatment. Follow-up on survival and cardiac function status through outpatient or telephone visits every six months after surgery, and patients underwent cardiac ultrasound examination one year after surgery. The main research endpoint was a composite endpoint of all-cause death, heart failure readmission, and heart transplantation, and the differences in cardiac function and cardiac ultrasound parameters between the two groups were compared. Results Ultimately 41 patients were collected, including 28 males and 13 females with an average age of 55.5±11.1 years. Twenty-five patients were in the surgery group and sixteen patients in the medication group. The median follow-up time was 16 months, ranging 1-96 months. The occurrence of all-cause death in the surgery group was lower than that in the medication group (HR=0.124, 95%CI 0.024-0.641, P=0.034). The difference between the two groups was not statistically significant in the composite endpoint (HR=0.499, 95%CI 0.523-1.631, P=0.229). The New York Heart Association (NYHA) grade of the surgery group was better (NYHA Ⅰ-Ⅱ accounted for 68.0% in the surgury group and 18.8% in the medication group, P<0.01) as well as the grade of mitral valve regurgitation (87.5% of the patients in the medication group had moderate or above regurgitation at follow-up, while all the patients in the surgery group had moderate below regurgitation, P<0.01). There was no statistical difference in preoperative and follow-up changes in echocardiograph parameters between the two groups (P＞0.05). Conclusion For non-ischemic functional mitral regurgitation, if the cardiac systolic function is well reserved, mitral valve surgery can improve survival and quality of life compare to simple medication therapy.

Objective To observe the relationship between functional connectivity(FC)of frontoparietal network(FPN)and cognitive function in patients with cerebral small vessel disease(CSVD)using resting-state functional MRI(rs-fMRI).Methods rs-fMRI of 50 CSVD patients with cognitive impairment(CI group),65 CSVD patients with normal cognition(NC group)and 60 healthy controls(HC group),as well as outcomes of neuropsychological tests were retrospectively analyzed.Brain regions with different FC of FPN were compared among 3 groups and between each 2 groups.Partial correlation analysis was used to evaluate the correlations of FC of brain regions value being statistically different between CI and NC groups and cognitive scores.Results Significant differences of FC in bilateral cingulate gyrus,left middle frontal gyrus,right supramarginal gyrus,right inferior parietal lobule and right medial superior frontal gyrus were found among groups(FWE correction,all P＜0.05).Compared with NC group,FC of left cingulate gyrus decreased,of right inferior frontal gyrus and right medial superior frontal gyrus increased in CI group(FWE correction,all P＜0.05).The decreased FC value of left cingulate gyrus was negatively correlated with clock drawing test score in CSVD patients(r=-0.159,P=0.049).Conclusion CSVD patients with or without CI had extensive abnormal FC of FPN,and the left cingulate gyrus was associated with patient's cognitive function.

Objective:To systematically review and integrate the caring experience of caregivers of lung transplant patients.Methods:Qualitative studies on the caregiving experience of caregivers of lung transplant patients were searched by computer from PubMed, Web of Science, Embase, Cochrane Library, China Biology Medicine disc, China National Knowledge Infrastructure and Wanfang data, and the search period was from establishment of the databases to April 30, 2023. The qualitative research quality evaluation criteria (2016 edition) of the Joanna Briggs Institute Evidence Based Health Care Center in Australia were used to evaluate the quality of the included literature, and the Meta-synthesis was used to integrate the literature results.Results:A total of ten articles were included, and 33 clear research results were extracted, which were summarized into eight new categories, and finally summarized into four integrated results, such as heavy burden experience, strong demand, positive experience and satisfaction with the medical service system.Conclusions:Medical workers should attach importance to and pay attention to the burden and needs of caregivers of lung transplant patients, provide professional and emotional support to caregivers, improve their caring ability and quality, and ultimately improve the quality of life of lung transplant patients.

Objective:To investigate the changes in gray matter volume of the subsystems as well as intra-subsystem and inter-subsystem functional connectivity in the default mode network (DMN) of relapsing-remitting multiple sclerosis (RRMS) patients with preserved cognitive function.Methods:In this prospective study, thirty-seven RRMS patients with preserved cognitive function who were admitted to Huashan Hospital of Fudan University from April 2020 to January 2021 (RRMS group) and 43 healthy volunteers (HC group) were recruited. Patients in the RRMS group received the cognitive assessment using a clinical cognitive functioning scale. Three-dimensional T 1WI and resting-state functional MRI were performed to obtain the brain structural and functional data. The DMN was divided into three subsystems: CORE, dorsal medial prefrontal cortex (DMPFC), and medial temporal lobe (MTL). The gray matter volume of the three subsystems were extracted from the gray matter volume map generated by spatial normalization; 24 regions of interest (ROIs) of the DMN were defined based on Yeo′s 17 networks, and their functional connectivity values were calculated to derive the mean intra-subsystem and inter-subsystem functional connectivity values. Differences in gray matter volume and functional connectivity between the RRMS and HC groups were compared using independent sample t-tests; Spearman′s partial correlation was used to analyze the correlation between subsystems′ gray matter volume and functional connectivity, as well as between subsystems′ functional connectivity and clinical scale scores. Results:Compared to the HC group, the gray matter volume of the three subsystems of the DMN were considerably reduced in the RRMS group ( P<0.05). The functional connectivity within and between the three subsystems were not statistically significantly different between the HC and RRMS groups ( P>0.05). Based on the ROI analysis, patients with RRMS the brain regions with significantly reduced DMN intra-subsystem functional connectivity values were mainly located in the left dorsomedial prefrontal cortex of the DMPFC, the right lateral temporal cortex of the DMPFC, and the left medial temporal cortex of the MTL, as compared with the HC group ( P<0.01). The gray matter volume of DMPFC was positively correlated with the functional connectivity within DMPFC in the control group ( r=0.326, P=0.040). In the RRMS group, the gray matter volume of CORE was positively correlated with the functional connectivity between CORE and DMPFC ( r=0.363, P=0.038), and the functional connectivity within CORE was positively correlated with scores on the memory and executive screening scale ( r=0.430, P=0.036). Conclusions:RRMS patients with preserved cognitive function exhibit gray matter atrophy in all three DMN subsystems. There is no correlation between the structure and function of the DMPFC subsystem. The functional connectivity within CORE subsystem may reflect memory and execution status; DMPFC and CORE may be critical encephalic regions for neurodegeneration and brain functional changes in RRMS patients with preserved cognitive function.

Objective:To compare the efficacy of modified single-incision and traditional double-incision for flexor hallucis longus tendon transfer in the treatment of Myerson type III chronic Achilles tendon ruptures in the middle-aged and elderly patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 106 patients with Myerson type III chronic Achilles tendon ruptures admitted to Ningbo No.6 Hospital from January 2015 to May 2021, including 54 males and 52 females; aged 48-82 years [(67.2±8.4)years]. Flexor hallucis longus tendon transfer was assigned to 60 patients using modified single-incision (modified single-incision group) and to 46 patients using traditional double-incision (traditional double-incision group). The operation time, intraoperative blood loss as well as American foot and ankle society (AOFAS) ankle-hindfoot score, foot and ankle outcome score (FAOS), visual analogue score (VAS) before operation, at postoperative 12 months and at the last follow-up were compared between the two groups. Time to recover walking and self-care ability, and incidence of complications were compared as well.Results:All patients were followed up for 16-52 months [(37.4±9.5)months]. The operation time and intraoperative blood loss were (51.6±7.4)minutes and (16.6±3.9)ml in modified single-incision group compared to (72.8±7.5)minutes and (32.9±5.2)ml in traditional double-incision group (all P<0.01). There was no significant difference in the AOFAS ankle-hindfoot score, FAOS and VAS between the two groups before operation (all P>0.05). At postoperative 12 months and at the last follow-up, AOFAS ankle-hindfoot score and VAS were not significantly different between the two groups (all P>0.05), but FAOS in modified single-incision group [(112.6±3.0)points, (114.4±3.1)points] was improved significantly compared with traditional double-incision group [(110.8±4.1)points, (112.7±4.3)points] ( P<0.05 or 0.01). At postoperative 12 months and at the last follow-up, the AOFAS ankle-hindfoot score, FAOS and VAS in both groups were improved or decreased significantly compared with those before operation (all P<0.05). All patients recovered their pre-injury daily activities. The time to recover walking and self-care ability were (9.6±2.0)weeks and (12.7±1.7)weeks in modified single-incision group compared to (10.8±1.8)weeks and (13.7±1.9)weeks in traditional double-incision group (all P<0.01). In modified single-incision group, superficial incision infection ( n=1) was found and cured after oral antibiotics. In traditional double-incision group, superficial incision infection ( n=2), deep incision infection ( n=1), deep venous thrombosis ( n=1) and medial plantar nerve injury ( n=1) were found and cured after symptomatic internal medical therapy; claw toe deformity ( n=2) was found and relieved after wearing customized insoles and functional exercise. The incidence of complications was 1.7% (1/60) in modified single-incision group compared to 15.2% (7/46) in traditional double-incision group ( P<0.01). Conclusion:In contrast with traditional double-incision surgery, modified single-incision for flexor longus tendon transfer in the treatment of Myerson type III chronic Achilles tendon ruptures in the middle-aged and elderly patients has advantages such as shorter operation time, less intraoperative blood loss, better functional recovery, faster postoperative recovery and less complications.

Objective With the help of computerized tomography (CT) and susceptibility-weighted imaging (SWI) examinations, to analyze and compare the incidence and the prevalent sites of microbleeds (CMBs) in control group, diabetes group, hypertension group and diabetic hypertension group with intracerebral CMBs. The risk factors for the onset of CMBs also will be explored, in order to provide a basis for the selection of clinical diagnosis and treatment options for CMBs. Methods A collection of 174 non-acute patients in the Department of Neurology of Shandong Electric Power Central Hospital from May 2019 to October 2020, including 101 males and 73 females, aged 45-89 years, with an average age of 72 ± 5 years. Divided into four groups according to disease types: Hypertension with type 2 diabetes group, Hypertension group, Type 2 diabetes group, Control group (no hypertension and type 2 diabetes). All patients underwent CT and MRI SWI sequence scans. The 4 groups of patients were matched in terms of gender and age, excluding the influence of gender and age. The incidence, number and distribution of CMBs in the four groups were counted, and the CT and SWI imaging manifestations of CMBs in the four groups were analyzed and compared. Results CT did not find the incidence of CMBs in the brain of patients. SWI imaging showed that CMBs were detected in 58 of 174 patients (incidence rate 33.3%), and CMBs occurred in 24 cases of diabetes and hypertension group (incidence rate 57.1%). CMBs occurred in 21 cases in the hypertension group (incidence rate 46.7%), 8 cases in the diabetes group (incidence rate 22.2%), and CMBs occurred in 5 cases in the control group (incidence rate 9.8%). The incidence of CMBs in the hypertension group and the diabetes combined with hypertension group was significantly higher than that in the control group (P < 0.05). There was no significant difference in the incidence of CMBs in patients with simple diabetes compared with the control group. Also, there was no significant difference in the incidence of CMBs between the diabetes combined with hypertension group and the simple hypertension group. Conclusion CT did not find the incidence of CMBs in the brains of patients in the non-acute phase. SWI could clearly show the CMBs of the enrolled patients. Diabetes is less likely to cause an increase in CMBs. Hypertension is significantly related to the occurrence of CMBs. CMBs associated with hypertension or/and diabetes are common in the basal ganglia and thalamus, which is different from cerebral amyloid angiopathy, which provides a basis for the choice of clinical treatment options.

Objective:To construct nursing-sensitive indicators system of perioperative pulmonary rehabilitation for patients in thoracicsurgery, so as to provide scientific monitoring standards for nursing quality of pulmonary rehabilitation.Methods:Based on the theory of enhanced recovery after surgery (ERAS) , evidence synthesis was conducted based on Johns Hopkins evidence-based nursing method for laying the foundation for nursing-sensitive quality indicators system of perioperative pulmonary rehabilitation.Based on the analysis results of the quality of nursing in the past two years, and though group discussion, appropriate indicators feasible to application were determined, and nursing-sensitive quality indicators, calculation formulas were preliminarily decided.

Positive coefficients of two rounds of expert consultation were both 100%, authority coefficients were 0.827 and 0.861, respectively, and the coordination coefficients were 0.309 and 0.372.Conclusion:The nursing-sensitive quality indicators system was scientific and practical and it was beneficial to regulate the behavior of nurses and improve the nursing quality of pulmonary rehabilitation.

This study shows the case of a patient with peroneus brevis tendon rupture in ankle fracture. The patient com-plained of swelling, pain and activity limitation in her right ankle caused by sprain. She was diagnosed with ankle fracture, supina-tion-adduction (Lauge-Hansen typing) by medical history, physical examination and imaging. The peroneus brevis tendon was not-ed complete ruptured when suturing the incision after ORIF, which was then repaired by "8" shaped suture. Based on literature re-view, the injury mechanism of the case may be because of overload inversion force toward to lateral inferior from the fracture of fib-ula on the peroneus brevis tendon. Additional attention should be paid to patients who suffered from an supination-adduction ankle fracture for whether peroneus brevis tendon tears before and during surgery.
