ABSTRACT

We investigated the ability of Dracocephalum moldavica (EPDM) flavonoids to protect human brain microvascular endothelial cells (HBMECs) from necroptosis induced by ischemia-reperfusion injury. To mimic the process of cerebral ischemia-reperfusion injury, a necroptosis model was established by treatment with the pan-cysteine aspartic acid protease (caspase) inhibitor Z-VAD-FMK combined with oxygen-glucose deprivation/re-oxygenation (OGD/R) injury using HBMECs. Cell proliferation and cytotoxicity (cell counting kit-8, CCK-8) was used to measure cell viability. A Hoechst33342/PI fluorescent double-staining method was exploited to determine the rate of cell necroptosis. A commercial kit was used to detect lactate dehydrogenase in the cell culture supernate. DCFH-DA probes, calcein AM and JC-1 probes were used to measure changes in ROS production, mitochondrial membrane permeability transformation pore (MPTP) opening and mitochondrial membrane potential (MMP), respectively. Enzyme-linked immunosorbent assay (ELISA) kits were chosen to detect the release of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6). Western blotting was used to detect necroptosis-related proteins. The results show that relative to control group, Z-VAD-FMK combined with OGD/R injury reduced cell viability, increased the necroptosis rate and the levels of LDH and ROS in HBMECs. The MPTP of the model group cells opened and the MMP reduced. TNF-α, IL-1β, and IL-6 levels were significantly elevated. Furthermore, the expression of receptor-interacting protein kinase 3 (RIP3) and mitochondrial phosphoglycerate mutase 5 (PGAM5) was significantly increased, accompanied by an increase of phosphorylated mixed-lineage kinase domain-like protein (p-MLKL)/MLKL. EPDM partially reversed the changes of the above-mentioned factors in HBMECs induced by Z-VAD-FMK plus OGD/R injury. These results indicate that EPDM may protect HBMECs from cerebral ischemia-reperfusion injury by inhibiting the RIP3/MLKL/PGAM5 pathway and MPTP opening to maintain mitochondrial function, thereby providing a scientific basis for the use of EPDM in the treatment of cerebral ischemia-related diseases.

ABSTRACT

Objective:To analyze the efficacy and safety of Daratumumab for the treatment of primary AL light chain systemic amyloidosis.Methods:Twenty one patients who were diagnosed as primary AL light chain systemic amyloidosis and treated with Daratumumab from 7 centers were retrospectively analyzed. Daratumumab was administrated as first line therapy in seven patients and 14 patients with relapsed settings. Hematological response, safety and survival were analyzed.Results:All 7 patients achieved very good partial response (VGPR) or better with first-line application of daratumumab. Three patients died, and the other four achieved organ remission. Among 14 relapsed patients, 2 patients had a difference of free light chain (dFLC) less than 20 mg/L before treatment, and 9 with a dFLC of more than 50 mg/L. All patients reached partial response (PR) or better, including 4 patients with complete response (CR), 3 with VGPR and 2 with PR. The response rate was 100% in 3 patients with dFLC 20-50 mg/L at baseline. The organ remission rate was 50% in patients with heart involvement and 58.3% in patients with kidney impairment. The overall median follow-up period was 5.3 months, and 11 months in surviving patients. One patient died of severe infection and disseminated intravascular coagulation (DIC) with stable amyloidosis. One patient switched to other regimens because dFLC elevated but did not fulfill progressive disease after 2 year application. As to safety, no grade 3/4 infusion reaction developed, and grade 1 infusion reaction occurred in 3 cases during the first infusion. Lymphocytopenia was seen in 75% patients including grade 3 or more in 30% patients.Conclusion:Daratumumab is effective to eliminate serum free light chain in both newly diagnosed and relapsed patients with systemic amyloidosis.

ABSTRACT

Objective:To analyze the impact of rare bacteria infection on clinical outcome in patients with diabetic foot ulcer(DFU).Methods:A total of 288 cases infected with single strains bacteria were selected. Data were grouped according to the 15 bacteria infection identified. The outcomes of healing, amputation, cardio and cerebrovascular events, and death were collected, and risk factors to the outcome were analyzed.Results:The rare infected bacteria were acinetobacter baumannii, staphylococcus epidermidis, morgan morganella, staphylococcus haemolyticus, streptococcus lactis, streptococcus agalactiae, enterobacter cloacae, and serratia marcescens.There were significant differences in age, albumin, HbA 1C, body mass index, condition of foot ulcer, degree of infection, healing, and minor amputation among these groups. Severe lower extremity arterial disease and age over 70 years were the main risk factors for the healing of ulcers. Wagner grade over 3 and infected with streptococcus lactis were the main risk factors for minor amputation. Severe lower extremity arterial disease, hemoglobin(Hb)≤90 g/L, and albumin(ALB)≤30 g/L were the main risk factors for major amputation. Estimated glomerular filtration rate <60 ml·min -1·(1.73 m 2) -1 and Hb≤90 g/L were the main risk factors for heart failure. Age over 70 years and ALB≤30 g/L were the main risk factors for death(All P<0.05). Conclusion:There exist significant differences in general condition, foot ulcer, and outcome in DFU patients infected with rare bacteria strains.

ABSTRACT

Objective:To discover the clinical features of nocturnal enuresis (NE) in adults and to detect factors that correlated with the symptom severity.Methods:This cross-sectional study recruited NE subjects from September 2017 through December 2020. All patients had experienced enuresis at least once per week and with a symptom duration of 3 months or longer. Followed by documentation of history and medical records, three-day bladder diary was adopted to assess their voiding pattern, and urodynamic parameters were obtained to evaluate lower urinary tract function.Results:A total of 106 NE patients (43 male and 63 female) were identified. There is no statistical difference regarding the average age (men: 57.8±15.6 vs. women: 56.1±14.0, P>0.05) and BMI (men: 23.9±3.4 vs. women: 23.3±4.3, P>0.05) between men and women. Comorbidities are extremely common in NE patients (n=85, 80.2%), with the incidence rate higher in men compared to women [88.4% (38/43)vs. 74.6% (47/63), P<0.05]. Hypertension (n=58, 54.7%), hyperlipemia (n=41, 38.7%), diabetes mellitus (n=38, 35.8%), coronary heart disease (n=22, 20.8%) were the most frequently reported conditions. On bladder diaries, subjects were frequently manifested nocturnal polyuria (NP, 47/106, 44.3%), reduced nocturnal bladder capacity (NBC, 74/106, 69.8%), or combination of both(33/106, 31.3%). Urodynamic studies suggested that the incidence of reduce bladder compliance, detrusor overactivity (DO), stress incontinence, bladder outlet obstruction(BOO), detrusor underactivity(DU)and detrusor hyperreflexia with impaired contractility(DHIC)was 27.4%(29/106), 39.6%(42/106), 17.9%(19/106), 9.4%(10/106), 25.5%(27/106)and 15.1%(16/106), respectively. Women were more likely to suffer from stress urinary incontinence [2.3%(1/43) men vs. 28.6% (18/63) women, P<0.01], while men were prone to have bladder outlet obstruction [ 23.3%(10/43) men vs. 0 women, P<0.01]. Correlation analysis demonstrated that obesity( r=0.63, P<0.01), systemic comorbidities( r=0.40, P<0.01), presence of NP( r=0.50, P<0.01) and NP+ NBC( r=0.47, P<0.01), post-void residual( r=0.53, P<0.01), reduced compliance( r=0.21, P=0.04), DU( r=0.28, P<0.01), stress incontinence( r=0.42, P<0.01)and DHIC ( r=0.35, P<0.01)are positively correlated with NE severity. Whereas, reduced Q max( r=-0.35, P<0.01), low capacity( r=0.21, P=0.03), and reduced bladder sensation( r=-0.21, P=0.03) correlate negatively with NE severity. Conclusions:The presence of NE is not only a sign of bladder dysfunction, but also an implication of obesity, systematic chronic diseases, urine production malfunctioning. Therefore, a thorough history regarding the lower urinary tract function and systemic comorbidities should be taken carefully, so that, an integrated and personalized treatment can be carried out.

ABSTRACT

Objective:In this study, lengthening over nail (LON) and plating after lengthening (PAL) were compared by the process of treatment and therapeutic effect in the children's femoral lengthening cases,to guide treatment choices; and in the PAL group there was another comparison between different timeline of plate fixation after lengthening to formulate reasonable technical route.Methods:Since January 7, 2014 to September 10, 2018, a total of 21 cases of LON and PAL surgery had been carried out, including 12 males and 9 females. The average age at their operation was 12.43±3.12 years. There were 10 patients in the LON group and 11 patients in the PAL group, in the PAL group 5 cases was synchronous fixation, which means removal of the external fixator and plate fixation would be performed in the same surgery, 6 cases was asynchronous fixation, which means plate fixation would be performed at least 2 weeks later after the removal offixator to reduce the risk of infection. The recorded data includesgender, date of birth, reason of discrepancy and treatment history, age at surgery, lengthening distance, the length of duration with frame, healing time, total duration time and total blood loss of seriesoperations, ROM of the knee joint, complications, etc.Statistical analysis was made by SPSS 22.0 software, and then reasonable treatment strategies were proposed.Results:In the LON group, the medianlengthening distance was 7.10 (6.63, 7.70) cm, the median total duration time was 300 (240, 330) min, the medianspeed of healing was 1.12 (0.78, 1.72) month/cm, complications were found in 3 cases, the median ROM of knee joint was 125.00° (117.50°, 150.00°); in the PAL group, the data respectively were 6.00 (5.00, 8.00) cm, 260 (230, 465) min, 1.00 (0.75,1.71) month/cm, 3 cases, 100.00° (90.00°, 150.00°), the difference between them was not statistically significant (all P>0.05). 2. In the PAL group, the difference of number of surgeries, total duration time, total blood loss, complication rate, healing speed and postoperative function between synchronous and asynchronous fixation was not statistically significant (all P>0.05). Conclusion:They are similarbetween LON and PAL techniques in the process of treatment and therapeutic effect. The surgeons could make choices according to the growth potential of the patients and their own custom operation methods. In the case of the current sample size, there is no statistical difference in the therapeutic effect between the synchronous and asynchronous plate fixation in the PAL method, but the sample size needs to be increased for further study.

ABSTRACT

Objective:To explore the lesion characteristics and predictors of invasive coronary angiography (ICA)-verified obstructive lesions with fractional flow reserve (FFR)>0.80, that is, anatomy-function mismatch.Methods:A total of 515 obstructive vessels in 419 coronary disease patients from 11 Chinese medical centers undergoing coronary CT angiography and ICA and FFR were retrospectively analyzed. All vessels had one target lesion with diameter stenosis ≥50 % by ICA. There were 229 vessels in the match group (FFR≤0.80) and 286 vessels in the mismatch group (FFR>0.80). The lesion characteristics including lesion territory, the distance of the coronary artery ostium to the proximal end of the lesion, minimum lumen area, reference lumen area, plaque length and burden, plaque volume and component volume, remodeling index and plaque morphological complexity were measured and compared between the two groups. Optimal thresholds of quantitative plaque characteristics were defined by Yoden index. Logistic regression analysis was used to analyze the predictors of anatomy-function mismatch. Area under receiver operating characteristic curve (AUC) was used to analyze the ability of different lesion features to predict mismatched lesions.Results:The coronary stenosis, plaque burden and length, plaque volume (including each component volume) in the mismatch group were smaller than those in the match group, and FFR, minimum lumen area were larger (all P<0.05). Left anterior descending artery (LAD) lesion and severe complex plaque were more common in the match group than the mismatch group with a statistically significant difference. Univariate logistic regression analysis showed that LAD lesion, minimum lumen area>4 mm 2, plaque burden and length, plaque calcification volume<27 mm 3, plaque lipid volume<30 mm 3, plaque fiber volume<150 mm 3 and plaque morphological complexity were predictiors of anatomic function mismatched lesions; Multivariate logistic regression showed that the minimum lumen area>4 mm 2 (OR=3.371, 95%CI 1.903-5.973, P<0.001), plaque lipid volume<30 mm 3 (OR=3.014, 95%CI 1.691-5.373, P<0.001), plaque morphological complexity (mild OR=17.772, 95%CI 8.072-39.128, P<0.001, moderate OR=6.383, 95%CI 3.739-10.896, P<0.001) were independent predictors of mismatched lesions. The AUC of the model based on the minimum lumen area, plaque lipid volume and morphological complexity was 0.824, which was superior to either of the plaque feature alone ( P<0.001). Conclusions:The minimum lumen area, lipid volume and plaque morphological complexity are independent predictors of the anatomical-functional mismatch lesions, and the combination can significantly improve the prediction value.

ABSTRACT

Objective:To compare short-term clinical efficacy between femoral neck system (FNS) and cannulated compression screws (CCS) in the treatment of femoral neck fractures in young adults.Methods:Retrospectively analyzed were the data of 94 patients with femoral neck fracture who had been admitted to Department of Orthopedics and Traumatology, The First Affiliated Hospital to University of Science and Technology of China, Department of Orthopaedics, The First Affiliated Hospital to Anhui Medical University and Department of Orthopaedics, The Second Affiliated Hospital to Anhui Medical University from October 2019 to October 2020. They were divided into 2 groups according to their modes of internal fixation: a FNS group ( n=47) and a CCS group ( n=47). In the FNS group there were 30 males and 17 females with a mean age of (47.8±9.8) years; in the CCS group there were 26 males and 21 females with a mean age of (43.7±13.1) years. The 2 groups were compared in terms of operation time, incision length, intraoperative blood loss, fracture healing time, weight-bearing time, Harris hip score and complications. Results:There was no significant difference in preoperative general data or follow-up duration between the 2 groups, showing comparability between groups ( P>0.05). In the FNS group, operation time [(47.7±9.4) min] was significantly shorter than that in the CCS group [(66.1±3.8) min], postoperative partial and full weight-bearing time [2.0 (2.0, 3.0) weeks, (6.4±2.1) weeks] significantly earlier than that in the CCS group [8.0 (3.0, 9.0), (10.1±3.4) weeks], fracture healing time [3.0(3.0, 4.0) months] significantly shorter than that in the CCS group [3.0(3.0, 4.0) months], Harris hip score at the last follow-up [95.0 (93.0, 95.0) points] significantly higher than that in the CCS group [90.0 (88.0, 95.0) points], incidence of lateral thigh irritation [0% (0/47)] significantly lower than that in the CCS group [31.9% (15/47)], and neck shortening length (4.3±3.9 mm) significantly shorter than that in the CCS group (6.9±4.5 mm) (all P<0.05). There was no significant difference in the rate of avascular necrosis of the femoral head or rate of internal fixation failure between the 2 groups ( P>0.05). Conclusion:In the treatment of femoral neck fractures in young adults, compared with CCS fixation, FNS fixation can shorten operation time and fracture healing time, allow patients to ambulate early after surgery, which is beneficial to maintenance of femoral neck length and to functional recovery of the hip.

ABSTRACT

Objective:To compare the curative effects of different venous cannulas and drainage to improve patient's whole body oxygenation during the auxiliary process of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) in lung transplantation.Methods:From December 2016 to December 2019, 12 patients who were assisted by VA-ECMO in one lung transplantation in People's Hospital of Henan Province were selected as the research objects. According to the number of side holes of venous cannulas, they were divided into two groups: one group with few side holes and other group with multiple side holes. The differences in blood gas indexes among the right radial artery, left radial artery, and right internal jugular vein before and after assistance were compared, and the assistance effect was evaluated.Results:The arterial partial pressure of oxygen (PaO 2) of blood gas indexes of the right and left radial arteries in both groups were significantly higher than that before assistance [mmHg (1 mmHg = 0.133 kPa): right and left radial artery in few side holes group: 79.5±4.2 vs. 48.3±3.8 and 88.1±3.5 vs. 48.3±3.8; right and left radial artery in multiple side holes group: 67.7±5.9 vs. 48.7±3.2 and 84.0±3.8 vs. 48.7±3.2, all P < 0.05]. The arterial partial pressure of carbon dioxide (PaCO 2) of blood gas index was significantly lower than that before assistance (mmHg: 44.2±2.6 vs. 71.7±4.4 for the right radial artery and 44.7±1.4 vs. 71.7±4.4 for the left radial artery in the group with few side holes; 46.2±2.1 vs. 71.2±3.5 for the right radial artery and 44.1±1.9 vs. 71.2±3.5 for the left radial artery in the group with multiple side holes, all P < 0.05). The partial pressure of oxygen in venous blood (PvO 2) of blood gas index of ECMO system in the group with few side holes was significantly lower than that of the multiport side holes group (mmHg: 56.4±3.2 vs. 88.7±1.5, P < 0.01), and the partial pressure of carbon dioxide in venous blood (PvCO 2) was significantly higher than that of multiport side holes group (mmHg: 63.6±3.7 vs. 44.2±1.7, P < 0.01). Conclusions:When VA-ECMO is used in lung transplantation, the superior vena cava blood flow can be fully drained by using intravenous cannula with few side holes. It can effectively improve the oxygenation of the upper body of lung transplant patients, avoid the dilemma of hypoxemia in the upper body and hyperxemia in the lower body, provide more effective assistance to patients undergoing single lung transplantation, and is more meaningful for improving the oxygenation status of the whole body in patients undergoing single lung transplantation.

ABSTRACT

Objective:To investigate the clinical effect of setting proportional pressure support (PPS) parameters by target tidal volume (VT) method.Methods:The study was conducted retrospectively on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients admitted to Tianjin Third Central Hospital from January 2016 to December 2020. According to the PPS parameter setting method, the patients were divided into the airway blocking group and target VT group. The baseline characteristics, initial setting values of flow assist (FA) and volume assist (VA), respiratory system parameters, and clinical outcomes were collected and compared between the two groups.Results:Fifty-nine patients were enrolled, 29 patients in the airway blocking group, and 30 in the target VT group. There was no statistically significant difference in baseline characteristics, compliance, resistance, and initial settings of FA and VA between the two groups. Compared with the target VT group, the respiratory rate (RR), mean arterial pressure (MAP), VT, and arterial partial pressure of oxygen (PaO 2) recorded 1 hour after the initial setting of the PPS parameters in the airway block method group were significantly reduced [RR (times/minute): 21.0 (18.5, 22.5) vs. 23.0 (21.0, 25.0), MAP (mmHg, 1 mmHg = 0.133 kPa): 84.0 (79.0, 90.5) vs. 90.0 (87.0, 96.2), VT (mL): 305.24±41.07 vs. 330.87±46.84, PaO 2 (mmHg): 68.0 (66.0, 73.5) vs. 74.0 (69.8, 82.5), all P < 0.05], while arterial partial pressure of carbon dioxide (PaCO 2) and oral closure pressure (P0.1) were both increased significantly [PaCO 2 (mmHg): 41.0 (39.0, 46.0) vs. 37.5 (35.0, 42.2), P0.1 (cmH 2O, 1 cmH 2O = 0.098 kPa): 1.42±0.78 vs. 0.90±0.67, both P < 0.05]. Compared with airway blocking group, the duration of weaning, ICU stay, and hospital stay in the target VT group were significantly shorter [duration of weaning (hours): 42.0 (24.0, 70.5) vs. 64.0 (30.5, 97.5), ICU stay: 10.00±3.38 to 13.28±5.41, hospital stay (days): 12.07±3.40 vs. 15.41±5.60, all P < 0.05]. There was no statistically significant difference in the invasive mechanical ventilation time, weaning failure rate, ICU mortality and in-hospital mortality between the two groups. Conclusion:This study suggested that the target TV method has the advantages of practicality, safety, convenience, and rapid to set PPS parameters than the airway block method, which shortens the duration of weaning and ICU stay, and has a good clinical prospect.

ABSTRACT

Objective:To analyze the possible causes of arrhythmia in patients receiving continuous renal replacement therapy (CRRT) with regional citrate anticoagulation (RCA).Methods:A retrospective cohort study was conducted. All patients underwent RCA-CRRT treatment from January 1, 2020 to October 31, 2020 in the intensive care unit (ICU) of Tianjin Third Central Hospital were enrolled. The patients were divided into arrhythmia group and non-arrhythmia group according to whether arrhythmia occurred. The gender, age, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, catheterization site, underlying diseases, electrocardiogram (ECG), electrolytes [total calcium, serum free calcium (iCa 2+), phosphorus, magnesium, potassium] and blood gas analysis (pH value, HCO 3-) of patients in the two groups were recorded. The changes of ECG were observed, the differences in electrolyte and blood gas analysis indexes between the two groups of patients at different time points (before CRRT, 24, 48, 72 hours after CRRT, and when arrhythmia occurred) were compared. Results:A total of 86 RCA-CRRT patients were enrolled, of which 12 cases (13.95%) had arrhythmia, and the remaining 74 cases (86.05%) had no arrhythmia. The average time for the occurrence of arrhythmia in the 12 patients was (44.00±16.82) hours. There was no significant ST-segment change in the ECG when the arrhythmia occurred compared with that before CRRT, the total calcium level was significantly higher than that before CRRT (mmol/L: 2.48±0.40 vs. 2.13±0.35, P < 0.05), the blood magnesium level was significantly lower than that before CRRT (mmol/L: 0.73±0.20 vs. 0.95±0.25, P < 0.05). There was no significant difference in iCa 2+, blood phosphorus, blood potassium, pH value and HCO 3- between before CRRT and when arrhythmia occurred. Over time, the total calcium levels in the two groups increased, and there was a statistical difference between the 48 hours after CRRT and before CRRT (mmol/L: 2.48±0.33 vs. 2.13±0.35 in the arrhythmia group, and 2.30±0.22 vs. 2.15±0.48 in non-arrhythmia group, both P < 0.05). The linear change trend of iCa 2+, pH value and HCO 3- was not obvious in the two groups. The blood phosphorus and blood magnesium levels in the two groups decreased. The blood potassium in the arrhythmia group decreased, however, the blood potassium level in non-arrhythmia group did not change significantly. The total calcium level in the arrhythmia group was significantly higher than that in the non-arrhythmia group at 72 hours after CRRT (mmol/L: 2.69±0.35 vs. 2.45±0.23, P < 0.05); however, there was no significant difference in serum iCa 2+, phosphorus, magnesium, potassium, pH value and HCO 3- between the two groups. Conclusion:Patients receiving RCA-CRRT were less likely to develop arrhythmia, the causes may be related to the accumulation of citric acid and electrolyte disturbances such as calcium, phosphorus, and magnesium.

ABSTRACT

Guided by the development of new medical science proposed by Ministry of Education and the "Education and Training Plan for Excellent Doctors 2.0", shifted from treatment-oriented to whole life-health cycle, we have explored curriculum ideological and political education in metabolic-related curriculum chain. Firstly, we constructed a core teaching team and had the training of curriculum ideological and political education. The top-level design was made with the integration of moral education into medical education. Secondly, the syllabus was comprehensively revised, containing the connotation of "morality education". The elements relevant to curriculum ideological and political education hidden behind professional courses were excavated. Finally, the mixed teaching mode of online combining with offline was carried out. Metabolism-related curriculum chain, focused on "metabolism, diabetes, obesity and patient education", formed a progressive link from basic medical science to practice to clinical, strengthening the "prevention, treatment and health care" based "one health" philosophy and giving full play to the implicit curriculum ideological and political education hidden behind professional courses. Our practice shows that the implementation of curriculum ideological and political education in metabolism-related curriculum has been accepted by students, and curriculum ideological and political education has been become part of professional courses. The "gene chimera" mode for curriculum ideological and political education incorporation into professional courses needs to be infiltrated imperceptibly, and the effect will be visualized in the future.

ABSTRACT

The diagnosis and treatment of traumatic brain injury (TBI) are basic skills that should be mastered by neurosurgery specialists during the standardized training. In view of the lack of TBI patients in our center, TBI training was entrusted to a joint base with more TBI patients. Based on clinical training and practice experience of the authors in recent years, including joint base introduction, basic requirement, theory and skill training, research training, humanity accomplishment improvement, inter-base communication and evaluation standard, we discuss the appropriate joint base training mode of TBI in standardized training of neurosurgery specialists, so as to provide reference for cultivating qualified and comprehensively developed neurosurgery specialists.

ABSTRACT

Objective:In this study, the feasibility of this method was evaluated in children with large distance femoral lengthening cases, and the acute correction and staging surgeries were compared at healing speed. At the same time the key points of surgical techniques would be summarized, so as to clarify the application value of this technology in children patients.Methods:Since July 7 of 2014 to January 16 of 2018, a total of 10 cases of Lengthening Over Retrograde Nail (LORN) surgery have been formulated and carried out, including 9 males and 1 females.The average age of the operation was 13.10±2.18 y. In all cases, the osteotomy point was located in the metaphysis of the distal femur, and the records from the first meeting to the end of follow-up included gender, date of birth, reason of discrepancy and treatment history, age at surgery, lengthing distance, the length of duration with frame, healing time, ROM of the knee joint, complications, et al. To compare the healing time of acute correction and staging surgery. Statistical analysis was made by SPSS 22.0 software, and then reasonable treatment strategies were proposed.Results:The average lengthing distance of 7.07±1.01 cm. The median time of the duration with frame was 8.5 (4,16) months, and the median follow-up time was 39 (34, 54) months. All cases obtained good clinical and imaging healing (1.70±1.10 month/cm vs. 1.16±0.54 month/cm), and all regained to normal walking function (136.67°±20.82° vs. 125.71°±26.37°), without the occurrence of fracture after therapy. There were no statistically significant differences in the speed of healing, range of joint motion or complication rate between acute correction and staging treatment. Conclusion:It is feasible for femoral lengthening surgery assisted by retrograde intramedullary nail in the treatment of femoral shortening deformityin children. The correction of mild angular deformity and lengthening surgery can be performed simultaneously. The osteotomy site was proposed at distal metaphysealof the femur for better quality of osteogenesis and shorter duration for fixator. It is safe to osteotomy and lengthening in the area of enchondroma.

ABSTRACT

Objective:To study the effect of early nursing intervention to prevent lymphedema of upper limb after breast cancer surgery and its effect on postoperative quality of life.Methods:Between July 2018 and March 2020, one hundred and seventeen cases of breast cancer, all female, admitted to department of thyroid and breast surgery, the affiliated Zhongshan hospital of Dalian University, were underwent modified radical mastectomy with axillary lymph node dissection. Fifty-eight cases were included in the control group whereas fifty-nine cases were in the intervention group. The control group received conventional nursing, the intervention group added early care intervention measures on the basis of conventional nursing. Follow-ups were carried out monthly in a period of 9 months post-surgery. The incidence and grade of lymphedema were compared between the two groups.Results:The incidences of lymphedema at 1,3,9 months after surgery were 8.5% (5/59), 8.5% (5/59), 10.2% (6/59) in the intervention group, which were lower than 31.0% (18/58), 36.2% (21/58), 43.1% (25/58) in the control group. Statistics showed significant difference between the two groups ( χ2 value was 9.425, 13.041, 16.289, P<0.05). The incidence of mild, moderate, and severe lymphedema were statistically different between the two groups ( χ2 value was 10.350, 12.078, 17.422, P<0.05). Follow-up for the quality of life was assessed using a 5-dimension evaluation method, including physical status, social/family status, emotional status, functional status and additional attention. One month follow-up showed 20.36±1.80, 20.03±1.68, 34.63±3.52, 15.86±1.96, 19.81±1.04 in the intervention group, all higher than the control group 17.03±1.36, 17.10±1.46, 19.38±1.51, 10.91±1.22, 18.36±1.21. Three-month follow-up showed 23.56±2.72, 23.73±2.20, 39.93±4.17, 20.31±3.04, 26.37±2.23 in the intervention group, higher than those of the control group 20.90±2.14, 19.12±2.63, 25.79±3.59, 13.97±2.67, 21.02±2.50. Nine month follow-up showed 27.44±2.01, 25.80±1.85, 40.88±3.72, 21.02±2.78, 27.02±2.45 in the intervention group, which were high than the control group 19.93±1.66, 20.67±1.46, 19.38±2.29, 16.33±2.65, 22.29±2.52. The difference between the two groups were statistically significant ( t value was 8.691-34.383, P<0.05). Conclusions:Early nursing intervention could prevent lymphedema of upper limb after breast cancer surgery, delay the progress of lymphedema, reduce the incidence and grade of lymphedema, and promote the rehabilitation of patients' affected limbs, improve quality of Life of patients, which is worthy of clinical application.

ABSTRACT

OBJECTIVE: To analyze the effect of gene-gene and gene-occupational stress interaction on hypertension in oil workers by Bayesian network(BN) analysis. METHODS: A total of 1 233 oil workers from Xinjiang Karamay Oilfield Company were selected as research subjects by the typical sampling method. The blood pressure was measured. The polymerase chain reaction-restriction fragment length polymorphism was used to evaluate the single nucleotide polymorphism(SNP) in α-adductin(ADD1) and β_2-adrenal receptor(β_2-AR) genes. The Effort-Reward Imbalance(ERI) Questionnaire was used to evaluate the ERI model occupational stress of oil workers. BN was used to analyze gene-gene and gene-occupational stress interactions. RESULTS: The detection rate of hypertension and ERI model occupational stress of these oil workers were 25.5%(315/1 233) and 47.4%(585/1 233) respectively. The AA, AG, and GG genotype and the frequency distribution of allele A and G at ADD1 rs17833172 were statistically different in these two groups(all P<0.05). There was no statistical significance in genotypes of GG, GT and TT at Gly460Trp rs4961(P>0.05); but the difference of the frequency of G and T alleles was statistically significant(P<0.05). There was no statistical significance in genotype distribution of AA, AG and GG, and frequency distribution of A and G in β_2-AR-1023 G/A rs2053044 and+252 G/A rs1042717(all P>0.05). After controlling the confounding factors including gender, education level, marital status, smoking, alcohol drinking and body mass index, the occupational stress group had a higher risk of hypertension than the no-occupational stress group(P<0.05, the odds ratio was 1.33, the 95% confidence interval was 1.01-1.74). The directed acyclic graph constructed by BN showed that the rs17833172 and Gly460Trp rs4961 sites of the ADD1 gene was directly associated with hypertension, and the β_2-AR+252 G/A rs1042717 site was indirectly associated with hypertension because of the ADD1 rs17833172 and Gly460Trp rs4961 sites. The interaction between occupational stress and ADD1 and β_2-AR was not associated with hypertension. CONCLUSION: The incidence of hypertension in oil field workers is correlated to occupational stress, and ADD1 gene rs17833172 and Gly460Trp rs4961 polymorphism. The gene-gene interaction between β_2-AR+252 G/A rs1042717 locus and ADD1 Gly460Trp rs4961 and rs17833172 locus is associated with hypertension, while the interaction between the four loci of ADD1 and β_2-AR and occupational stress has no effect on hypertension in the oil workers.
