Objective:To observe any effect of combining interactive scalp acupuncture with constraint-induced movement therapy (CIMT) in treating the upper extremity motor function of children with spastic hemiplegic cerebral palsy.Methods:Fifty-seven children with spastic hemiplegic cerebral palsy were randomly divided into a control group of 28 and an observation group of 29. The control group was given conventional rehabilitation and routine CIMT, while the observation group was additionally provided with interactive scalp acupuncture. In the observation group the CIMT lasted for 30 minutes while the needles were retained. Then, after the needles were removed, the family administered simple rehabilitation training for 2.5 hours guided by a rehabilitation therapist. The treatments were administered 5 days per week for 3 weeks as a session, and the whole treatment consisted of 3 sessions. Before, as well as 1 month and 3 months after the treatment, upper extremity motor function in both groups was evaluated using the Melbourne assessment scale 2 (MA2) and the fine motor Peabody developmental motor scales. Muscle tone in the children′s elbow flexors was assessed using the modified Ashworth scale (MAS).Results:After both 1 and 3 months of treatment, the average MA2 scores of both groups were significantly better than those before treatment, with those of the observation group significantly superior to the control group′s averages. After both 1 and 3 months, both groups′ visual-motor integration scores, grasping ability scores and total scores had improved significantly, with those of the observation group significantly better than in the control group, on average. The MAS scores of both groups were also significantly better than before the treatment, but with no significant differences between the two groups at either time point.Conclusions:Interactive scalp acupuncture combined with constraint-induced movement therapy can significantly improve the upper extremity motor functioning and fine motor ability of children with spastic hemiplegic cerebral palsy.

Objective To evaluate the application of ELISA randomized quality control,and continuously improve the laboratory testing capacity and quality assurance,in order to gradually improve the application of randomized quality control to the daily testing of ELISA.Methods Collected the quality control data of KEHUA HBsAg,compared the difference between randomized quality control data and immobilized quality control data.Group comparison of randomization quality control between rows and columns.The randomized quality control data were analyzed retrospectively and the quality control chart was established by using the randomized quality control data.Analyzed and compared the lost-control situation of randomized quality control and immobilized quality control.Results Randomized quality control S/CO value(2.831±0.343)and immobilized quality control S/CO value(2.651±0.260)in the same microplate,the difference between two was statistically significant(t=5.970,P＜0.05).The differences between randomized quality control and immobilized quality control in columns 2 to 8 were statistically significant(t=2.285～5.536,all P<0.05).There were no statistically significant differences between randomized quality control and immobilized quality control in column 9 to 12(t=0.031～1.605,all P>0.05).There was no statistically significant difference in randomization quality control among all lines(F=0.858,P＞0.05).The randomized quality control data was used to establish a quality control chart.Within the time range of the collected data,the randomized quality control was out of control for 6 times,all were greater than+3s,and the loss of control rate was 4.72%(6/127).Fixed position quality control lost control 9 times during the same period,all of which were greater than+3s,with a loss of control rate of 0.61%(9/1 481).Conclusion The randomized quality control has a greater possibility to reflect the factors affecting all the samples on the microporous plate.Random quality control can be used to find possible systematic errors in testing.Randomized quality control can gradually be fully applied to daily indoor quality control,but the loss of control rate and coefficient of variation may increase.

OBJECTIVE: To investigate the role of α7-nicotinic acetylcholine receptor (α7-nAChR) in the regulation of neuronal activity and expression of synapse-related proteins in the thalamic reticular nucleus (TRN) of insomnia rats treated by acupuncture. METHODS: A total of 36 male Sprague-Dawley (SD) rats of clean grade were randomly divided into a control group, a model group, an acupuncture group, and an acupuncture+antagonist group, with 9 rats in each group. The model group, the acupuncture group, and the acupuncture+antagonist group were treated with intraperitoneal injection of p-chlorophenylalanine (PCPA) to establish insomnia model. After successful modeling, the acupuncture group and the acupuncture+antagonist group received acupuncture at bilateral Neiguan (PC6) and Zusanli (ST36) once daily for 5 consecutive days. Thirty min before each acupuncture session, the acupuncture+antagonist group was intraperitoneally injected with methyllycaconitine citrate (MLA), an α7-nAChR antagonist, at a dosage of 5 mg/kg while the acupuncture group received the same volume of 0.9% sodium chloride solution. The rats' daytime spontaneous activity was observed. Neuronal discharge in the TRN was detected using neuroelectrophysiological methods. Immunofluorescence staining was used to detect parvalbumin-positive (PV⁺) neurons and co-expression of PV⁺ and postsynaptic density protein-95 (PSD-95) in the TRN. RESULTS: Compared with the control group, the model group showed increased daytime spontaneous activity (P<0.01); decreased average fluorescence intensity and positive number of PV⁺ neurons in the TRN (P<0.01); decreased neuronal discharge frequency (P<0.01), prolonged inter-discharge intervals (P<0.01) in the TRN; reduced number of PV⁺/PSD-95 double-positive cells in the TRN (P<0.01). Compared with the model group, the acupuncture group showed decreased daytime spontaneous activity (P<0.01); increased average fluorescence intensity and positive number of PV⁺ neurons in the TRN (P<0.01); increased neuronal discharge frequency (P<0.01), shortened inter-discharge intervals (P<0.01) in the TRN; increased number of PV⁺/PSD-95 double-positive cells in the TRN (P<0.05). Compared with the acupuncture group, the acupuncture+antagonist group exhibited increased daytime spontaneous activity (P<0.01); reduced average fluorescence intensity and positive number of PV⁺ neurons in the TRN (P<0.01); decreased neuronal discharge frequency (P<0.05), prolonged inter-discharge intervals (P<0.05) in the TRN; reduced number of PV⁺/PSD-95 double-positive cells in the TRN (P<0.01). CONCLUSION α7-nAChR are involved in mediating the regulatory effect of acupuncture on circadian rhythm disturbances in PCPA-induced insomnia rats. Blocking α7-nAChR attenuates the activating effect of acupuncture on TRN neurons, and reduces the expression of PSD-95 protein on GABAergic neurons.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

BACKGROUND:Nowadays,there are increasing reports on the digitization and visualization system of acupuncture points for adults in traditional Chinese medicine,and the digitization and visualization system of acupuncture points for children in traditional Chinese medicine and the simulation system of acupuncture manipulation for Mongolian medicine training have been reported.However,there are no reports on relevant systems for children in Mongolian medicine. OBJECTIVE:To develop a simulation system of acupuncture points for children in Mongolian medicine,in the hope that it can be used for clinical teaching,manipulation practice and research on acupuncture safety. METHODS:Based on the tomographic anatomical dataset of preschool boys,a three-dimensional(3D)digital virtual anatomical model of children with multiple internal organs and tissues was constructed by using PhotoShop.2021 and Digihuman Reconstruction System software.The relevant annotation information database of 27 acupoints such as Dinghui acupoint of Mongolian medicine was compiled by the Unity database language.The Mongolian gold needle and silver needle were selected to record the acupuncture point teaching video on the 3D printed head and neck resin model of children.In Unity3D software,children's anatomical model,acupoint annotation information database and acupuncture operation video were integrated and coded,and a 3D digital children's Mongolian acupuncture acupoint visualization system integrating simulation acupuncture training,clinical teaching and acupuncture safety research was successfully created. RESULTS AND CONCLUSION:This study was based on real children's specimens.In order to reduce the error of two-dimensional segmentation,the manual layer-by-layer segmentation section image method was used to ensure the accuracy of the 3D model to the greatest extent.The Digihuman Reconstruction System was used to extract and save the individual segmentation data while maximizing the accuracy of the 3D model.PhotoShop.2021 software was used to complete the 3D reconstruction of the outer skin of the head and neck of children and the internal bony structure,cervical spinal cord,blood vessels and nerves,muscles and ligaments.After 3D reconstruction,the basic morphology of each independent structure and the integrity of the overall contour were verified in MeshLab software and the final fine adjustment and anatomical position confirmation were conducted using 3-matic research 13.0 software.The real anatomical morphology of the head and neck of preschool children was successfully simulated and restored.Unity3D software was used to integrate the 3D model of children,acupuncture operation video and acupoint annotation database,and the 3D digital Mongolian acupuncture acupoint visualization system for children was successfully constructed.Based on the real continuous fault ultra-thin dataset of preschool boys in China,China's first 3D digitization and visualization system of acupuncture points in the head and neck of children in Mongolian medicine was developed.Compared with the previous acupuncture soft works,this system is more suitable for the anatomical morphological development characteristics of Asian children,and has a high value of application in the fields of research on the safety of acupuncture in Mongolian medicine,clinical teaching and acupuncture simulation training.

Objective:To investigate the application value of donor liver autologous portal venous blood rinse in orthotopic liver transplantation (OLT).Methods:The retrospective cohort study was conducted. The clinicopathological data of 35 pairs of donors and recipients who underwent OLT in the First Affiliated Hospital of University of Science and Technology of China from May 2018 to June 2019 were collected. Of the 35 donors, there were 31 males and 4 females, aged (48±9)years. Of the 35 recipients, there were 25 males and 10 females, aged (47±9)years. Of the 35 recipients, 16 recipients undergoing donor liver autologous portal venous blood rinse were allocated into the portal vein group, and 19 recipients undergoing donor liver albumin water rinse were allocated into the albumin group. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and compari-son between groups was analyzed using the t test. Measurement data of skewed distribution were represented as M(range). Count data were descried as absolute numbers, and comparison between groups was analyzed using the Fisher exact probability. Results:(1) Surgical situations. The anhepatic phase time and arterial blood Ca 2+ concentration within 5 minutes after reperfusion of the recipients were (52±12)minutes and (0.99±0.10)mmol/L in the portal vein group, versus (64±12)minutes and (1.05±0.07)mmol/L in the albumin group, showing significant differences in the above indicators between the two groups ( t=2.94, 2.22, P<0.05). The mean arterial pressure, arterial blood K +concentration and arterial blood pH within 5 minutes after reperfusion of the recipients were (70±24)mmHg (1 mmHg=0.133 kPa), (4.7±1.3)mmol/L and 7.27±0.06 in the portal vein group, versus (71±28)mmHg, (4.6±1.1)mmol/L and 7.30±0.07 in the albumin group, showing no significant difference in the above indicators between the two groups ( t=0.14, 0.30, 1.22, P>0.05). (2) Post-operative situations. Cases with post-reperfusion syndrome (PRS), cases with severe PRS of cardiac arrest, cases with primary graft nonfunction of the recipients were 6, 0, 2 in the portal vein group, versus 8, 1, 1 in the albumin group, showing no significant difference in the above indicators between the two groups ( P>0.05). Total bilirubin on postoperative day 7 of the recipients was (90±52)μmol/L in the portal vein group, versus (166±112)μmol/L in the albumin group, showing a significant difference between the two groups ( t=2.66, P<0.05). International normalized ratio on postoperative day 7, the highest alanine aminotransferase and aspartate aminotransferase within 7 days after operation of the recipients were 2.1±2.0, (1 952±2 813)IU/L and (3 944±6 673)IU/L in the portal vein group, versus 1.8±0.6, (1 023±1 014) IU/L and (2 005±2 910)IU/L in the albumin group, showing no significant difference in the above indicators between the two groups ( t=0.66, 1.23, 1.08, P>0.05). Recipients with hepatic artery complication and biliary complication were 1 and 2 in the portal vein group, versus 0 and 4 in the albumin group, showing no significant difference in the above indicators between the two groups ( P>0.05). There were 3 cases and 2 cases died during the perioperative period in the portal vein group and the albumin group, respectively. (3) Follow-up. Of the 35 recipients, 30 recipients were followed up for 534(range, 28?776)days after operation. During the follow-up, there were 3 patients with postoperative complications in the portal vein group including 2 cases died and 1 case recovered after sympto-matic treatment. There were 5 patients with postoperative complications in the albumin group including 1 case died and 4 cases recovered after symptomatic treatment. Up to the follow-up date, 11 patients in the portal vein group and 16 patients in the albumin group were in good condition. Conclusion:Rinse of the donor liver with autologous portal venous blood during liver transplantation can shorten the time of anhepatic phase, without increasing the occurrence of post-reperfusion syndrome, ischemia re-perfusion injury and biliary tract complications.

Objective:To assess the differences in multidimensional clinical manifestations between patients with irritable bowel syndrome (IBS) matching the Rome Ⅲ criteria but not matching Rome Ⅳ and IBS patients matching the Rome Ⅳ criteria, among patients diagnosed with IBS according to Rome Ⅲ criteria.Methods:From November 2016 to October 2017, a total of 472 IBS patients admitted to six hospitals were selected, which included Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology (139 cases), Sir Run Run Shaw Hospital, School of Medicine of Zhejiang University (95 cases), the First Affiliated Hospital of Dalian Medical University (96 cases), the Affiliated Hospital of Guizhou Medical University (90 cases), the People′s Hospital of Guangxi Zhuang Autonomous Region (20 cases), and the Second Affiliated Hospital of Xi′an Jiaotong University (32 cases). The 472 IBS patients were divided into the group that matching the Rome Ⅳ criteria (Rome Ⅳ group), and the group that matching the Rome Ⅲ criteria but not matching the Rome Ⅳ criteria (Rome Ⅲ group). The basic characteristics (IBS course, post-infectious IBS, history of smoking or drinking, etc.), abdominal symptoms, and defecation-related symptoms of two groups were compared and analyzed by face-to-face questionnaires. Multi-dimensional clinical manifestations assessment was completed by questionnaires, which included gastrointestinal symptom rating scale (GSRS), irritable bowel syndrome-severity scoring system (IBS-SSS), irritable bowel syndrome-quality of life (IBS-QOL), and hospital anxiety and depression scale (HADS). Independent sample t-test, rank sum test, and chi-square test were used for statistical analysis. Results:There were 344 patients (72.9%) in Rome Ⅳ group and 128 patients (27.1%) in Rome Ⅲ group. The IBS course of patients in Rome Ⅳ group was longer than that in Rome Ⅲ group (3.0 years (7.0 years) vs. 2.0 years (5.7 years)), and the difference was statistically significant ( Z=-2.73, P=0.006). The GSRS scores of loose stools and abdominal pain of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group, and the GSRS scores of increased exhaust and abdominal distension of IBS patients in Rome Ⅳ group were lower than those in Rome Ⅲ group (3.0(2.0) vs. 2.0(4.0), 3.0(2.0) vs.1.0(2.0), 1.5(3.0) vs. 2.0(3.0), 1.0 (3.0) vs. 2.0(3.0)), and the differences were statistically significant ( Z=-2.48, -9.90, -2.11 and -2.06, P=0.013, <0.001, =0.035 and =0.040). The proportions of fatigue and dizziness of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group (58.4% (201/344) vs. 43.0% (55/128), 30.8% (106/344) vs. 29.7% (38/128)), and the differences were statistically significant ( χ2=8.37 and 12.36, P=0.004 and <0.001). The scores of anxiety and depression subscales of the HADS of IBS patients in Rome Ⅳ group were higher than those in Rome Ⅲ group (6.5 (6.8) vs. 6.0 (6.0), 5.0 (6.0) vs. 3.0 (5.0)), and the differences were statistically significant ( Z=-2.58 and -2.40, P=0.010 and 0.017). The scores of IBS-SSS scale, abdominal pain severity, abdominal pain frequency, and impact on quality of life of IBS patients in Rome Ⅳ group were all higher than those in Rome Ⅲ group (249.5 (108.0) vs. 177.0 (111.8), 50.0 (25.0) vs. 20.0 (30.0), 50.0 (70.0) vs. 10.0 (30.0), 66.0 (42.0) vs. 42.5 (34.0)), and the differences were statistically significant ( Z=-7.79, -9.64, -10.65 and -2.48, P<0.001, <0.001, <0.001 and =0.013). The score of IBS-QOL for behavioral disorder of IBS patients in Rome Ⅳ group was lower than that in Rome Ⅲ group (74.5±21.6 vs. 79.2±17.7), and the difference was statistically significant ( t=-2.22, P=0.027). Conclusion:The clinical symptoms of patients mathching the Rome Ⅳ criteria are more typical and severe, as compared with those of IBS patients matching the Rome Ⅲ criteria but not matching the Rome Ⅳ criteria.
