Objective To investigate the clinical efficacy of low molecular weight heparin (LMWH)-assisted plasma exchange (PE) in the treatment of patients with hyperlipidemic severe acute pancreatitis (HLSAP).Methods Patients with HLSAP diagnosed and treated in Leshan People's Hospital were retrospectively selected from January 2023 to April 2024 and their clinical data were analyzed.According to the diagnosis and treatment plans,they were divided into the control group (PE) and the study group (LMWH-assisted PE).The coagulation function[fibrinogen (Fib),thrombin time (TT),activated partial thromboplastin time (APTT) and prothrombin time (PT)],plasma specific viscosity,lipid levels[total cholesterol (TC),triglyceride (TG)],inflammatory factors[white blood cell count (WBC),erythrocyte sedimentation rate (ESR),C reactive protein (CRP),amylase (AMY) and lipase (LYP)]were compared before and after treatment between the two groups.The duration of continuous renal replacement therapy (CRRT),length of hospitalization and incidence of new organ dysfunction were compared between the two groups.Results A total of 105 HLSAP patients were included in the study,with 50 in the control group and 55 in the study group.Before treatment,there was no statistically significant difference in coagulation function,lipid levels,plasma specific viscosity and inflammatory factors between the two groups (P>0.05).After treatment,Fib,TC,TG,plasma specific viscosity,WBC,ESR,CRP,AMY and LYP were significantly lower in the study group than in the control group (P<0.05),while TT,APTT and PT were significantly higher than in the control group (P<0.05).The duration of CRRT,hospitalization time and incidence of new organ dysfunction were lower in the study group than in the control group (P<0.05).In terms of adverse reactions,no transfusion adverse reactions and serious complications occurred in both groups during the treatment period.Conclusion LMWH-assisted PE has a better effect in the treatment of HLSAP,which can improve the coagulation function,blood lipid levels and inflammatory factors of HLSAP patients,shorten the hospital stay and the duration of CRRT,and reduce the incidence of new organ dysfunction.

Objective:To investigate the clinical efficacy of modified Guipi Decoction combined with omeprazole in the treatment of acute non-variceal upper gastrointestinal bleeding (ANVUGIB) with failure of the spleen to control blood vessels syndrome.Methods:Prospective cohort study. A total of 120 patients from January 2018 to December 2021 Taihe County Hospital of Traditional Chinese Medicine with ANVUGIB of failure of the spleen to control blood vessels syndrome were selected, and the patients were divided into observation group and control group according to the random number table method, with 60 cases in each group. The control group was treated with a large dosage of proton pump inhibitor (omeprazole injection was injected intravenously first, and then omeprazole enteric coated tablets were taken); the observation group took Guipi Decoction on the basis of the control group, and both groups were treated for 7 days. TCM syndrome score, Hemoglobin (Hb) and hematocrit (HCT) levels were measured by colorimetry before and after the treatment. BUN was detected by urease glutamate dehydrogenase method. Prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen (FIB) levels were detected by immunoturbidimetry. The adverse reactions during treatment were recorded and the clinical efficacy was evaluated.Results:Two patients in the observation group and two patients in the control group dropped out of the study. After treatment, the scores of main symptoms, secondary symptoms and total scores in the observation group were lower than those in the control group ( t values were respectively 10.73, 4.45, 7.98, P<0.05). After treatment, the levels of HCT [(41.25 ± 5.03)% vs. (38.19 ± 5.26)%, t=2.95], Hb [(81.09 ± 5.23) g/L vs. (78.39 ± 5.37) g/L, t=2.74] in the observation group were higher than those in the control group ( P<0.01), and BUN [(4.38±0.96) mmol/L vs. (5.39 ± 1.13) mmol/L, t=5.19] was lower than that in the control group ( P<0.01); PT [(12.48 ± 0.67) s vs. (13.22 ± 0.73) s, t=5.69], APTT [(24.66 ± 2.29) s vs. (27.78 ± 2.04) s, t=7.75] were lower than those in the control group ( P<0.01), and FIB [(3.68 ± 0.62) g/L vs. (3.41 ± 0.74) g/L, t=2.13] level was higher than that in the control group ( P<0.05). The total effective rate of the observation group was 93.1% (54/58), and that of the control group was 79.3% (46/58), with statistical significance ( χ2=4.64, P=0.031). During the treatment, the incidence of adverse reactions in the control group was 3.4% (2/58), while that in the observation group was 1.7% (1/58), without statistical significance ( χ2=0.34, P=0.559). Conclusion:High-dosage omeprazole treatment with the addition of internal administration of Guipi Decoction can significantly improve coagulation function, correct the signs and symptoms associated with insufficient blood volume in the body circulation, improve hemostatic efficiency, and reduce the risk of bleeding in patients with ANVUGIB, without increasing the risk of patient safety with the drug.

ObjectiveTo explore a feasible animal model of dysphagia after stroke. MethodsTwenty-two clean Sprague-Dawley rats were randomly divided into normal group (n = 11) and model group (n = 11). The model of dysphagia after stroke was established by the thread embolism, and the normal group received no intervention. The latency of the first swallowing attack and the number of swallowing were recorded three and seven days after modeling. The cerebral infarction was detected by TTC staining, and the neuronal apoptosis in ischemic brain was detected by TUNEL fluorescence staining. ResultsCompared with the normal group, the swallowing latency prolonged and the number of swallowing reduced three days in the model group, however, there was no significant difference (P > 0.05); seven days after modeling, the swallowing latency prolonged (P < 0.05), and the number of swallowing slightly reduced with little significant difference (P > 0.05). Compared with the normal group, the brain tissue showed obvious infarction area and a large number of apoptotic cells, while the body mass reduced in the model group (P < 0.05). ConclusionThe model rats express some features of dysphagia, which may become a transformation model of dysphagia after stroke.

Objective:To evaluate the treatment of infected nonunion after internal fixation of subtrochanteric fracture with a reconstruction stent of external fixation.Methods:A retrospective study was conducted to analyze the data of 5 male patients with infected nonunion after internal fixation of subtrochanteric fracture who had been treated and completely followed up at The Great Wall Orthopaedics and Hand Surgery Hospital from January 2017 to October 2022. The patients were (30.0±13.5) years old. Seinsheimer fracture types: ⅢA (1 case), ⅢB (1 case), Ⅳ (2 cases), and Ⅴ (1 case); original internal fixation: intramedullary system (4 cases) and plate fixation (1 case); the Cierny-Mader anatomical classification: type Ⅳ (diffuse type) for all. After complete debridement at stage one, 2 or 3 hydroxyapatite (HA) coated screws were placed at both fracture ends from the lateral side of the femur for unilateral reconstruction external fixation. Next, a hybrid external fixation scaffold was added with a 1/3 ring at the sagittal position and 1 or 2 HA screws in 4 cases while unilateral reconstruction external fixation was constructed at both sides by inserting 2 HA screws into both fracture ends from the anterior femur at the sagittal position in 1 case. Antibiotic bone cement was used to fill bone defects of (3.8±1.8) cm. At 6 to 8 weeks after debridement when infection did not recur, antibiotic bone cement was removed before autogenous iliac bone grafting was performed in 3 patients and osteotomy bone transport in 2 patients. Infection control, bone union time, time for removal of external fixation stent, complications, Sanders hip function score and Paley bone outcome score were recorded.Results:The 5 patients were followed up for (23.4±8.1) months after surgery. Infection at the fracture ends was controlled after 1 time of debridement in 3 patients and after 2 times of debridement in 2 patients. The loosening HA screws were replaced twice due to infection at the proximal nail tract, and autologous bone grafting was performed at the opposite fracture ends in 1 case; no complications occurred in the other 4 cases. Bony union was achieved at the extended segment and fracture ends in all patients. The time for imaging union after bone reconstruction was (10.2±3.4) months. The time for wearing a stent of external fixation was (18.0±4.5) months. There was no recurrent infection or lingering infection. According to the Sanders hip function score at the last follow-up, 4 cases were excellent and 1 case was good; according to the Paley bone outcome score, the curative effect was excellent in all.Conclusion:Application of a reconstruction stent of external fixation combined with antibiotic bone cement can control infection at the first stage and conduct bone reconstruction at the second stage to successfully treat the infected nonunion and preserve the hip function after internal fixation of subtrochanteric fracture.

ObjectiveChronic heart failure （CHF） is the terminal stage of cardiovascular disease. The adverse cardiovascular events of CHF patients with weakness have increased significantly. Traditional Chinese medicine （TCM） has a good effect on CHF. However，there are few reports on the clinical observation of the treatment of CHF with weakness in elderly patients by TCM combined with conventional health-preserving exercises. This study aimed to explore the clinical efficacy of Qiangxin decoction combined with Baduanjin in the treatment of elderly patients with CHF and weakness. MethodSixty CHF patients with Qi deficiency，blood stasis，and water retention syndrome admitted to the Cardiovascular Department of the First Affiliated Hospital of Guangxi University of Chinese Medicine from January 2020 to December 2021 were enrolled. The patients in the control group were treated with conventional western medicine according to the guidelines，while those in the treatment group received additional Qiangxin decoction and Baduanjin exercise based on the therapeutic protocol of the control group. The levels of serum N-terminal B-type brain natriuretic peptide precursor （NT-proBNP），creatine kinase （CK），lactate dehydrogenase （LDH），free fatty acid （FFA），left ventricular ejection fraction （LVEF），left ventricular end-diastolic dimension （LEVDD），6-minute walk distance （6MWD），Minnesota Living with Heart Failure Questionnaire （MLHFQ）， and Tilburg Frailty Indicator （TFI） scores of the two groups were observed before and one month after treatment. At the same time，the re-admission within three months was compared between the two groups. ResultThere was no significant difference between the two groups in terms of the general data and the therapeutic indexes before treatment. After treatment，the NT-proBNP，CK，LDH，FFA，LVEDD，MLHFQ， and TFI scores of the two groups were lower than those before treatment（P<0.05，P<0.01）， and the LVEF and 6MWD were higher（P<0.05，P<0.01）. The efficacy of the treatment group was superior to that of the control group after treatment （P<0.05，P<0.01）. The re-admission rate within three months in the treatment group was 7.1% （2/28）， lower than 30.8% （8/26） in the control group （χ²=4.897，P<0.05）. ConclusionQiangxin decoction combined with Baduanjin is helpful to improve the body energy metabolism，heart function，quality of life，and weakness level of elderly CHF patients with weakness， and reduce the rate of re-admission.

Objective:To observe the effects of different kinesio taping methods on hand swelling, shoulder pain, upper limb motor function and ability in the activities of daily living of stroke survivors with shoulder-hand syndrome.Methods:Sixty stroke survivors with shoulder-hand syndrome were randomly divided into groups A, B, C and a control group, each of 15. In addition to routine rehabilitation training and drug treatment, as well as claw-shaped and I-shaped taping of the hand and wrist, group A received I-shaped kinesio taping, B received Y-shape and C received I-shape plus Y-shaped taping of the shoulder. Before and after 4 weeks, the drainage method was employed to calculate the difference in volume between the two hands. Their temperatures were also measured. The subjects reported shoulder pain using a visual analog scale (VAS). Upper limb motor functioning was quantified using Fugl-Meyer scores, and difficulties in the activities of daily living were evaluated using the modified Barthel index (MBI).Results:Before the treatment there were no significant differences among the four groups in terms of any of the measurements. Afterward the treatment, significant improvement was observed in the volume and temperature differences between hands, as well as in the VAS, FMA and MBI scores. After the treatment, group C′s average FMA score was significantly higher than those of the other groups. There was no significant difference in MBI scores among the four groups.Conclusions:Supplementing rehabilitation training with I-shaped plus Y-shaped kinesio taping can effectively reduce the volume and temperature differences between the hands, relieve shoulder pain, and improve effectiveness in the activities of daily living of persons with shoulder-hand syndrome after a stroke. Hand-claw and wrist-I taping also have some effect.

With the rapid development and adaptation of high-throughput sequencing in clinical settings, application of exome sequencing (ES) has been gradually expanded from pediatric to prenatal diagnosis in recent years. There is an urgent need to establish criteria for clinical grade ES in order to facilitate such a complex testing. The standardization of pre- and post-test consultation, quality control for sample processing process and validation of bioinformatics data analysis, and more importantly data interpretation and reporting, as well as appropriate reporting scope, is of great importance for health care stakeholders. To achieve this, a committee composed of a wide range of healthcare professionals has proposed an ES standard for prenatal diagnosis. This has provided expert opinion on the genetic counseling and reporting standards of prenatal ES for the purpose of applying ES technology in prenatal setting.

Objective To investigate the role of network platform for treatment and rescue of acute and severe cerebrovascular diseases in improving treatment level of patients with acute ischemic stroke.Methods The differences of number of patients accepted venous thrombolysis, number of patients accepted emergency intravascular interventional treatment, and time from admission to intravenous thrombolysis (door to needle time [DNT]) were analyzed in patients with acute ischemic stroke admitted to our hospital in the first year (2016) and the second and third years (2017 and 2018) of construction of network platform for treatment and rescue of acute and severe cerebrovascular diseases in Yunfu city. The National Institutes of Health Stroke Scale (NIHSS) scores were compared in 120 patients selected randomly from online referral (study group,n=60) and non-online referral (control group,n=60) within the same time periods in 2018.Results In 2017 and 2018, the number of patients accepted intravenous thrombolysis was 85 and 103, respectively, and the rate of intravenous thrombolysis was 9.92％ and 9.83％; they were all significantly larger/higher than those in 2016 (n=50, 6.97％,P<0.05). In 2017 and 2018, the number of patients accepted emergency endovascular treatment was 56 and 129, respectively, and the emergency endovascular treatment rate was 6.53％ and 12.31％; they were all higher than those in 2016 (n=44 and 6.14％), and the differences between those in 2018 and 2016 were statistically significant (P<0.05). The DNT ([82.00±18.75] min in 2017 and [77.00±32.17] min in 2018) was significantly shorter than that in 2016 ([109.00±30.58] min,P<0.05). The NIHSS scores of the study group and control group were 4.70±3.64 and 8.90±5.62, respectively, after one week of treatment, both of which were lower than those before treatment (14.30±6.29 and 13.60±6.37); and after treatment, the NIHSS scores of the treatment group were statistically lower than those of the control group (P<0.05). Conclusion Construction and effective operation of network platform for treatment and rescue of acute and severe cerebrovascular diseases is an effective guarantee to improve the success rate of treatment for patients with acute ischemic stroke.

Objective To evaluate the value of 3D printing technology to assist in the repair of severe damage to the radial side hand.Methods From March,2014 to September,2016,there were 9 cases suffered from varying degrees of metacarpal and phalangeal bones injuries with soft tissue destruction at the radial side of the hand.The donor and recipient areas were scanned by 64 row spiral CT before operation.Three dimensional images were obtained by CTA 3D reconstruction technology.Preoperative plan was designed by using Mirror image technology and Virtual surgery aided design technique of Mimics software virtual surgery aided design system.Nine cases were treated with first toe toenail flap with dorsal foot flap combined with second phalangeal bone transplantation to reconstruct thumb and anterolateral thigh perforator flap to repair the wound.The cutting area of the dorsalis pedis flap and anterolateral thigh perforator flaps ranged from 4.0 cm × 5.5 cm to 6.5 cm × 9.5 cm and from 9.5 cm ×17.0 cm to 12.0 cm × 25.5 cm,respectively.Postoperative followed-up was performed to evaluate the effect of the operation.Results All 9 thumbs and flaps survived after the operation.Postoperative followed-up time ranged from 8 to 16 months.The appearance of reconstructed thumb was close to normal,and the two-point discrimination was from 8.0 to 11.0 mm.According to the evaluation criteria of upper limb function of the Chinese Academy of Medical Sciences,7 cases were excellent and 2 cases were good.The survival flaps had soft texture,good blood circulation and satisfactory appearance at the repaired site.Conclusion 3D printing technology assists thumb reconstruction and wound repair for severe damage to the radial side of the hand with good clinical results.

Objective: To evaluate the impact of KIT D816 mutation on the salvage therapy in relapsed acute myeloid leukemia (AML) with t(8;21) translocation. Method: The characteristics of the first relapsed AML with t(8;21) translocation from 10 hospitals were retrospectively collected, complete remission (CR₂) rate after one course salvage chemotherapy and the relationship between KIT mutation and CR₂ rate was analyzed. Results: 68 cases were enrolled in this study, and 30 cases (44.1%) achieved CR₂. All patients received KIT mutation detection, and KIT D816 mutation was identified in 26 cases. The KIT D816 positive group had significantly lower CR₂ compared with non-KIT D816 group (23.1% vs 57.1%, χ²=7.559, P=0.006), and patients with longer CR₁ duration achieved significantly higher CR₂ than those with CR₁ duration less than 12 months (74.1% vs 31.9%, χ²=9.192, P=0.002). KIT D816 mutation was tightly related to shorter CR₁ duration. No significant difference of 2 years post relapse survival was observed between KIT D816 mutation and non-KIT D816 mutation group. Conclusion KIT D816 mutation at diagnosis was an adverse factor on the salvage therapy in relapsed AML with t(8;21) translocation, significantly related to shorter CR1 duration, and can be used for prediction of salvage therapy response. KIT D816 mutation could guide the decision-making of salvage therapy in relapsed AML with t(8;21) translocation.
