Objective:To evaluate the efficacy in decompression of lateral femoral cutaneous nerve (LFCN) through a small incision, following precise localisation with auxiliary examinations, in the treatment of meralgia paraesthetica (MP) caused by pelvic fractures.Methods:A retrospective study was conducted on 6 patients with MP caused by pelvic fractures at the Department of Hand Surgery, Huashan Hospital, Fudan University between June 2019 and June 2022. Among the 6 patients with MP caused by pelvic fractures, 4 were treated conservatively, 1 received an internal fixation with a steel plate, and the other received an internal fixation with screws. The average time after the injury to surgery was 5.33 (range: 3-7) months. Preoperative ultrasound and CT scans were performed to identify the sites of compression on LFCN. After the decompression of LFCN, Visual analog scale (VAS) scores were employed to compare the therapeutic effectiveness with what that before surgery, at 3 months and within 1 year (7-11 months) after surgery. SPSS 26.0 data statistical was used analysis software for data analysis and processing, the data was represented as (Mean ± SD). Friedman test was used to compare the differences in VAS scores among 6 patients before surgery, at first postoperative follow-up, and second postoperative follow-up. If the differences were statistically significant, pairwise comparisons were further conducted, and the Bonferroni correction method was used to adjust the significance level. P<0.05 indicated a statistically significant difference. Results:After the LFCN decompression, all patients showed a decrease in VAS scores with significantly reduced area of skin paraesthesia at the first postoperative follow-up review. At the second review, all patients scored VAS zero, except 1 who was scored 2. There was a statistically significant difference compared to preoperative VAS scores (Friedman test: χ2=12.0, P=0.002; paired t-test: P=0.002). Conclusion:For the meralgia paraesthetica caused by pelvic fractures, compression points on LFCN can be easily identified through auxiliary examinations. Precise release of the LFCN from compression through a small incision, after an accurate localisation, provides a rapid and complete relief of pain and sensory abnormalities.

ObjectiveTo investigate the current status and development needs of evidence-based medicine （EBM） capability in ethnic minority medicine， and explore effective strategies to enhance EBM capability in this field. MethodsThe questionnaire survey was conducted in various ethnic minority medical institutions and research organisations. The questionnaire covered three dimensions， firstly， perceptions and attitudes towards evidence-based medicine； secondly， advantages and challenges in the development of ethnic minority medicine； thirdly， demands and recommendations for enhancing evidence-based medicine capability in ethnic minority medicine. ResultsA total of 501 valid questionnaires were collected， of which 103 questionnaires were collected by re-sending to minority medicine regions with insufficient participation. The questionnaires included 354 responses （70.66%） from practitioners of minority medicine， including Tibetan medicine， Mongolian medicine， Uyghur medicine， Zhuang medicine， and Korean medicine. Among the 501 questionnaires， 146 respondents （29.14%） indicated that they knew about EBM， 355 respondents （70.86%） had either a "general understanding" or had "not heard about" EBM before， and 469 respondents （93.61%） believed that introducing ECM could promote the development of ethnic minority medicine. The primary challenge in promoting EBM in the field of ethnic minority medicine is the lack of professionals in EBM and a lack of understanding of how to apply it into clinical practice （442 respondents， 88.22%）. In the 9-point importance rating for enhancing evidence-based abilities， high scores were achieved in standardization of clinical practice guidelines （7.50±1.90） and methods for sample sizes in clinical research （7.45±1.90）. Regarding the demand for improving clinical research literacy， expert academic lectures， and experience sharing （404 respondents， 80.64%） and evidence-based methodology monographs on ethnic minority medicine （401 respondents， 80.04%） were emphasized. ConclusionsPractitioners in ethnic minority medicine hold a positive attitude towards integrating EBM. However， there remains substantial room for the education and dissemination of EBM. Enhancing evidence-based capabilities can be achieved through specific measures such as cultivating or recruiting talents in EBM， establishing evidence-based support platforms for clinical research， organizing regular academic lectures and exchanges， and strengthening the construction of theoretical frameworks and evaluation systems tailored to ethnic minority medicine， thereby following a path of evidence-based practices aligned with the unique characteristics of ethnic minority medicine.

It has been proposed by Basic Questions On Proper Therapies for Different Diseases Geographically （《素问·异法方宜论篇》） that "wei （痿） diseases should be treated by Daoyin （导引）". Furthermore， it is clarified that the indications of Daoyin are those conditions related to spleen and dampness caused by dampness pathogen， excessive food intake and less exercise， and mainly manifested as heavy limbs， fatigue and flaccidity， which is similar to the metabolic imbalance in the early stage of glucose or lipid metabolism disorder in modern medicine. Based on modern clinical and basic research evidence， Daoyin can inhibit the response of inflammation， alleviate oxidative stress， regulate intestinal microbiota， and modulate gene expression to improve metabolic abnormalities， and this will provide ideas for researches on the indications of Daoyin.

OBJECTIVE: To investigate the effectiveness of distal radius core decompression in the treatment of chronic wrist pain caused by various etiologies. METHODS: A retrospective analysis was performed for the clinical data of 10 patients with chronic wrist pain treated with distal radial core decompression between January 2018 and December 2021. There were 6 males and 4 females with an average age of 37.4 years (range, 21-55 years). The disease duration ranged from 7 to 72 months, with an average of 26.5 months. Preoperative MRI examination showed that 10 cases had bone marrow edema at the distal radius on the affected side, and 8 cases had bone marrow edema in the carpal bones such as scaphoid and lunate bone. Among them, 3 patients had a history of wrist fracture, and 2 patients had Kienböck diseases (1 case each in stage ⅡB and stage ⅢA). Three cases were combined with triangular fibrocartilage complex (TFCC) type 1A injury. Two cases were combined with osteoarthritis, 1 of them was complicated with severe traumatic arthritis, the wrist arthroscopy showed that the TFCC was completely lost and could not be repaired, and the cartilage of the lunate bone and the ulnar head were severely worn.Visual analogue scale (VAS) score was used to evaluate the relief of wrist pain before operation, at 6 months after operation, and at last follow-up, and the range of motion of the affected wrist in dorsiflexion, palmar flexion, ulnar deviation, and radial deviation was measured. The degree of bone marrow edema was evaluated according to T1WI, T2WI, and STIR sequences of MRI. RESULTS: All the patients were followed up 12-22 months, with an average of 16.4 months. Except for 1 patient who experienced persistent wrist joint pain and limited mobility after operation, the remaining 9 patients showed significant improvement in pain symptoms and wrist joint mobility. The VAS score and range of motion of wrist dorsiflexion, palmar flexion, ulnar deviation, and radial deviation at 6 months after operation and at last follow-up were significantly improved when compared with those before operation, the VAS score and the range of motion of wrist ulnar deviation and radial deviation at last follow-up were further improved when compared with those at 6 months after operation, all showing significant differences ( P<0.05). There was no significant difference in wrist dorsiflexion and palmar flexion between at 6 months after operation and at last follow-up ( P>0.05). Bone marrow edema was improved in 6 patients on MRI at 6 months after operation, and was also improved in other patients at last follow-up. CONCLUSION For chronic wrist pain caused by a variety of causes, distal radius core decompression can directly reduce the pressure of the medullary cavity of the distal radius, improve the blood supply of the corresponding distal structure, significantly alleviate chronic wrist pain, and provide an option for clinical treatment.

Objective:To investigate the relationship between sleep quality and slow-flow in patients with acute coronary syndrome during percutaneous coronary intervention(PCI) and its impact on clinical prognosis.Methods:200 patients with ACS hospitalized in the cardiology department of Guangzhou First People's Hospital from January 2017 to October 2018 were selected. The Pittsburgh Sleep Quality Index (PSQI) was measured before elective PCI, and the sleep breathing of patients was monitored by micro motion sensitive mattress sleep monitoring system (MSMSMS). The patients were divided into normal sleep group (68 cases, PSQI≤7 points) and sleep disorder group (132 cases, PSQI>7 points). The levels of plasma endothelin-1 (ET-1) and nitric oxide (NO) were measured. The " slow-flow" that took place during PCI were also recorded. Major cardiac adverse events (MACE) of patients took placed during 12 months follow-up periods were recorded and compared between two groups.Results:Compared with normal sleep group, patients in sleep disorder group had higher ratio of sleep apnea-hypopnea syndrome (SAHS), hypoxemia and lower deep sleep (25.00% vs 10.29%, 25.76% vs 11.76%, 66.67% vs 48.53%, all P<0.05); lower level of NO and higher level of ET-1 [(28.65±3.26)μmol/L vs (30.24±4.08)μmol/L; (21.17±3.08)pg/ml vs (18.90±2.95)pg/ml, P<0.05]; more slow-flow events took place during PCI in sleep disorder group than normal sleep group (16.67 vs 5.88%, P<0.05); After 12 months of follow-up, Kaplan-Meier survival analysis showed patients of the two groups had significantly different cumulative non-events survival rates (19.70% vs 7.35%, Log rank=5.06, P=0.025). Conclusions:Sleep disorder increase the slow-flow phenomenon during PCI in patients with ACS and affect the clinical prognosis.

Objective:To investivate the relationship of serum estradiol and oxidative stress with microcirculation resistance in women with syndrome X.Methods:A total of 120 patients with syndrome X who were hospitalized in the Department of Cardiology in Guangzhou First People's Hospital from January 2015 to January 2019 were enrolled. All patients underwent coronary angiography and pressure wire examination and were divided into two groups according to the index of microcirculation resistance (IMR). Forty healthy people in the medical examination center were used as controls in the same period. The level of serum estradiol, interleukin-1 (IL-1), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD) were measured among three groups.Results:The rate of diabetes mellitus in high IMR group was higher than that in control group and low IMR group ( P<0.05). There was no significant difference between low IMR group and control group ( P>0.05). The levels of serum estradiol and SOD were significantly lower in high IMR group than those in low IMR group and control group. The levels of IL-1 and TNF-α were significantly higher in high IMR group than those in low IMR group and control group ( P<0.05). These indexes have the same relationship between low-IMR group and control group ( P<0.05). The level of serum estradiol was negatively correlated with the levels of IL-1 and TNF-α in high and low IMR groups and positively correlated with the level of SOD in these groups. Multivariate logistic regression analysis showed that diabetes, low serum estradiol level, low SOD level, high IL-1 level, high TNF-α level were the independent risk factors for microcirculation resistance in women with syndrome X ( P<0.05). Conclusions:The decreased serum estradiol is an important factor for coronary microcirculation disorders in women with syndrome X. The decrease of serum estradiol level leads to the loss of the corresponding antagonistic effect in oxidative stress state, which may be one of the important mechanisms of the formation and progress of coronary microcirculation disorder.

Objective:To investigate the current situation of cytomegalovirus (CMV) infection in infants in Lishui, and summarize the related factors of CMV infection, evaluate its influence on the growth and development of infants, and provide evidence for the prevention and control of CMV infection.Methods:In this study, 2 254 cases of infants admitted in pediatric ward in Lishui Maternal and Child Health Hospital, Qingtian County People′s Hospital, Suichang County People′s Hospital, Qingyuan County People′s Hospital from January 1, 2015 to December 31, 2017 with integral clinical data were selected. All the babies were followed up from the time when they were born to 1 year old. The serum CMV antibody and the urine CMV-DNA were screened, the general situation and clinical features of CMV infection were summarized, and the relevant factors of infants CMV infection were analyzed and screened by the single factor and multiple factors analysis. They were followed up to 1 year old to clarify the influence of CMV infection on the growth and development of infants.Results:From 2015 to 2017, the total positive infection rate of CMV-IgM in infants under 1 year old in Lishui was 10.43%(235/2 254), and CMV-IgM positive infection decreased year by year. The positive rate of CMV-IgG did not change significantly with time. The positive rate of CMV-IgM was the highest at 1—3 months, and up to 15.29% (61/399). The positive rate of CMV-IgM decreased with the age of the babies. The positive rate of CMV-IgG increased with the age of the babies. The positive rate of CMV-IgM in infants showed no significant difference in gender ( P>0.05). The positive rate of CMV-IgM was higher in men than that in women [65.43% (810/1 238) vs. 55.51% (564/1 016)], and there was significant difference ( P<0.05). The gestational age of the infected group was lower than that of the non-infected group [(37.41 ± 1.63) weeks vs. (38.97 ± 0.97) weeks], and the breast-feeding rate of the infected group was higher than that of the non-infected group [57.87%(136/235) vs. 40.00%(40/100)], and there were significant differences ( P<0.05). Thrombocytopenia, the increase of transaminase, necrotizing enterocolitis of newborn, and hepatosplenomegaly of infected group is higher that of the non-infected group [18.72%(44/235) vs. 1.00% (1/100), 29.36% (69/235) vs. 13.00% (13/100), 26.81% (63/235) vs. 10.00% (10/100), 9.79% (23/235) vs. 0], and there were significant differences ( P<0.05). Gestational age and breast-feeding were possible risk factors for CMV infection in infants under 1 year old ( P<0.05). There was no significant difference in height, weight, head circumference and intelligence score between the infected group and the non-infected group at the age of 1 year ( P>0.05). The total abnormal rate of hearing development and the abnormal detection rate of B-ultrasound in the infected group were higher than those in the non-infected group [13.62%(64/470) vs. 1.00%(2/200), 6.38%(15/235) vs. 0], and there were significant differences ( P<0.05). Conclusions:The CMV active infection rate of infants under 1 year old in Lishui is relatively high and decreases year by year. It decreases with the prolongation of birth time, and there is no gender difference. Gestational age and breast-feeding are the risk factors for active CMV infection in infants. CMV infection affects the hearing development and the brain development of infants under 1 year old, which is the main cause of hepatitis. It is necessary to pay attention to the prevention of CMV infection, strengthen maternal perinatal health care, and strengthen the screening of CMV infection in high-risk groups.

Objective Investigation of the significance for applying the percentage of neutrophils, neutrophil to lymphocyte ratio combined with contrast enhanced ultrasonography in the diagnose of coronary artery disease through examining the percentage of neutrophils, neutrophil to lymphocyte ratio on peripheral blood. Methods 130 patients with acute coronary syndrome (ACS group) , 90 patients with stable angina (SAP group) and 50 nonCAD patients (control group were observed. The neutrophils counts of all the patients were detected and Neut％, NLR were calculated; all the patients were asked to examine enhanced carotid contrast echocardiography. The plaque enhancement (DE) , and luminal enhancement ratio (Ratio) were recorded. The differences in neut％, NLR and CEUS were compared among the three groups. The Pearson correlation analysis was used to analyze the correlation between Ratio and Neut％, NLR. Multivariate logistic regression analysis was used to evaluate the predictive value of Neut％, NLR and CEUS for ACS. Results (1) The value of Neut％, NLR of the peripheral blood, DE, and Ratio in both ACS group and SAP group were higher than those in control group, and the value of ACS group was higher than that in SAP group (P < 0.05 or P < 0.01); (2) The analysis of Linear correlation showed that the ratio of CEUS in ACS patients was positively correlated with Neut％ (r = 0.422, P = 0.001) and NLR (r = 0.407, P = 0.001). (3) The ROC results showed that circulating Neut％, NLR and DE, Ratio play a significant role in the diagnose of unstable plague in CAD patients; (4) Multivariate logistic regression analysis showed that Neut％, NLR, DE, Ratio were independent indicators of the ACS patients (P< 0.05 or P < 0.01).Conclusions Contrast enhanced carotid examination combined with leukocyte analysis on peripheral blood were useful to detect plaque instability and inflammatory response in CAD patients, and it also provide lots of objective evidence for predicting and intervening unstable plaque in CAD patients.

Objective To investigate the predicting value of Notch1 levels expressed in peripheral blood mononuclear cell (PBMC) for coronary artery calcification.Methods 300 consecutive patients with coronary artery disease (CAD) who hospitalizing in the department of cardiology in Guangzhou first people's hospital from January 2016 to June 2017 were enrolled.All Patients received 320-slice multi-detector row computed tomography scanning and coronary artery calcium sore(CCS)were measured.Patients were divided into three groups:control group (CCS =0),Low CCS group (CCS ＜97.6) and high CCS group (CCS ≥97.6) according to the mean value of CCS (CCS =97.6).Notch1 expressed in PBMC,serum interlekin-6 (IL-6) and high sensitivity C reactive protein (hs-CRP)of patients were examined and compared among three groups.Results The levels of Notch1 in PBMC and serum IL-6,hs-CRP of patients in high CCS group were significant higher than the other two groups [Notch1:7.02 ± 0.86 vs 6.32 ± 0.78 vs 5.49 ± 0.71;IL-6:(133.66 ± 10.18) μg/L vs (127.49 ± 10.79) μg/L vs (111.62 ± 9.87) μg/L;hs-CRP:(3.98 ± 1.02) mg/L vs (3.11 ±0.95)mg/L vs (2.56 ±0.76)mg/L] (P ＜0.05).The Spearman correlation analysis showed that the levels of Notch1 in PBMC were positive correlated with the levels of serum IL-6 and hs-CRP in enrolled patients with coronary calcification (P ＜ 0.05).Multivariate logistic regression analysis showed that the levels of Notch1 in PBMC and serum IL-6 were two strong independent risk factors for severity of coronary calcification in patients with CAD (P ＜ 0.05).Conclusions Notch1 expression in PBMC of patients with CAD was valuable to predicate the severity of coronary calcification.That the Notch1 signal path regulating the inflammation conditions in patients may be one of the most important mechanisms in the formation and progress of coronary calcification.

Objective To investigate the effect of renal sympathetic denervation (RSD) on the activity of renalase in dogs with chronic heart failure (CHF).Methods After induced by abdominal aorta constriction,dogs were divided into three groups according to whether they underwent double renal artery ablation:2 dogs in control group,2 dogs in sham-operated group (no renal artery ablation),and 5 dogs in RSD group (renal artery ablation).Plasma noradrenaline (NE),B-type natriuretic peptide (BNP),and renalase were determined in 5 dogs with RSD (RSD group),2 control dogs (control group),and 2 shamoperated dogs (sham-operated group).Results NE,BNP and heart rate were significantly higher and renalase was lower in CHF group than those in control group (all P ＜ 0.05).Compared to the control dogs with CHF,the levels of renalase were significantly increased in 6 weeks after RSD [(1 948.78 ±49.19) ng/ml vs (1 847.35 ±20.72)ng/ml,P =0.029],and NE [(166.30 ±7.68)pg/ml vs (181.29 ±8.57)pg/ml],and BNP [(75.10 ± 5.58)lμg/ml vs (89.79 ± 2.04) μg/ml] were decreased in 8 weeks after RSD (all P ＜ 0.05).An decreased trend of the levels of renalase was observed in 8 weeks than in 6 weeks in CHF dogs after RSD,without significant difference (P ＞ 0.05).Conclusions The activity of renalase in dogs with CHF can be affected by RSD.
