Exploration of Decision-Making Methods Based on Syndrome Differentiation by “Data-Knowledge” Dual-Driven Models： A Case Study of Gastric Precancerous State / 中医杂志

Data analysis models may assist the transmission of traditional Chinese medicine （TCM） experience and clinical diagnosis and treatment， and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis， and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases， syndrome elements， evolution of pathogenesis， and syndrome differentiation protocols； knowledge-driven is to make use of data and information to promote decision-making and action processes， and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy， and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research， we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state， and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile， the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained， and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored， so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.

Multidisciplinary approach for the management of term pregnancy complicated by Eisenmenger syndrome / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Pregnancy in patients with Eisenmenger syndrome (ES) is associated with high maternal mortality rates of 30%‒50%, or even up to 65% in the case of a cesarean section (Yuan, 2016). Here, we report a case of term pregnancy complicated with ES and severe pulmonary artery hypertension (PAH), which was managed by a multidisciplinary team (MDT) and resulted in an uncomplicated delivery via elective cesarean section. The goal of this study is to emphasize the importance of multidisciplinary approach in the management of pregnancy with ES, which can profoundly improve maternal and infant outcomes.

Efficacy of robot-assisted arthroscopic anterior cruciate ligament reconstruction / 中华创伤杂志

Objective:To compare the clinical efficacy of robot-assisted and simple arthroscopic reconstruction of anterior cruciate ligament (ACL).Methods:A retrospective cohort study was conducted to analyze the clinical data of 37 patients with ACL tear admitted to Honghui Hospital of Xi′an Jiaotong University from January 2020 to September 2020. There were 24 males and 13 females, aged 16-45 years［(30.7±9.8)years］. A total of 17 patients were treated by robot-assisted ACL reconstruction (robot-assisted group), and 20 patients by simple arthroscopic ACL reconstruction (simple arthroscopy group). The operation time, number of guide wire drilling, positional accuracy of bone tunnel (distance between the central point of bone tunnel and ideal anatomical point) and perioperative complications were compared between the two groups. Knee stability was evaluated by Lachman test and KT-2000 measurement, and knee function by Lysholm score, International Knee Documentation Committee (IKDC) score and range of motion of joint flexion and extension before operation, at 4 months after operation and at the last follow-up.Results:All patients were followed up for 12-18 months［(13.1±4.1)months］. The operation time in robot-assisted group was (83.8±11.3)minutes, significantly longer than (50.4±9.1)minutes in simple arthroscopy group ( P<0.01). The number of guide wire drilling in robot-assisted group was (2.2±0.5)times, less than (2.5±0.4)times in simple arthroscopy group ( P<0.05). The distance between the central point of bone tunnel and ideal anatomical point was (1.3±0.3)mm in robot-assisted group, not significantly different from (1.4±0.3)mm in simple arthroscopy group ( P>0.05). There were no perioperative complications in both groups. The two groups showed no significant differences in Lachman test, KT-2000 measurement, Lysholm score, IKDC score and range of motion of joint flexion and extension before operation, at 4 months after operation and at the last follow-up (all P>0.05). The above indices in both groups were significantly improved at 4 months after operation and at the last follow-up as compared with those before operation (all P<0.01), and both groups showed no significant difference in the above indexes at 4 months after operation and at the last follow-up as compared with those before operation (all P>0.05). Conclusion:Compared with simple arthroscopic ACL reconstruction, robot-assisted ACL reconstruction can prepare a bone tunnel once with good location and direction in one time and achieve similar results in stability and functional recovery of the joint except for slightly longer operation time.

Efficacy of arthroscopic anchor fixation of medial collateral ligament combined with anterior and posterior cruciate ligament reconstruction in the treatment of type KD-IIIM dislocation of knee joint / 中华创伤杂志

Objective:To compare the clinical effect of anchor fixation of medial collateral ligament（MCL）and non-repaired treatment combined with arthroscopic anterior and posterior cruciate ligament reconstruction in the treatment of type KD-IIIM（Schenck classification）dislocation of knee joint.Methods:A retrospective case-control study was conducted to analyze the clinical data of 41 patients with type KD-IIIM dislocation of the knee joint admitted to Xi'an Honghui Hospital of Xi'an Jiaotong University from September 2015 to September 2017. There were 26 males and 15 females，with the age range of 15-62 years［（37.7±13.9）years］. A total of 21 patients were treated by arthroscopic anterior and posterior cruciate ligament reconstruction and anchor fixation of MCL（repaired group）and 20 patients by arthroscopic anterior and posterior cruciate ligament reconstruction without MCL repair（non-repaired group）. The perioperative complications were observed. Comparisons between the two groups were made before operation，4 months after operation and at the last follow-up in terms of Lysholm score，International Knee Documentation Committee（IKDC）score，Visual Analogue Scale（VAS）and range of motion of joint flextion and extension. The medial opening distance of stress X-ray of lower limbs was also observed at the last follow-up.Results:All patients were followed up for 48-66 months［（54.4±5.1）months］. No perioperative complications were noted. The Lysholm score，IKDC score，VAS and range of motion of joint flextion and extension showed no statistical differences between the two groups before operation（ P>0.05），and all were improved from the preoperative level at 4 months after operation and at the last follow-up（ P<0.05）. The Lysholm score in repaired group were（69.7±5.1）points and（83.8±4.9）points at 4 months after operation and at the last follow-up，significantly higher than those in non-repaired group［（61.0±5.5）points and（74.6±6.0）points］（ P<0.05）. The IKDC score in repaired group was（71.8±4.0）points at 4 months after operation，significantly higher than that in non-repaired group［（71.1±3.9）points］（ P<0.05）. The IKDC score in repaired group was（82.3±5.1）points at the last follow-up，similar with that in non-repaired group［（83.2±4.0）points］（ P>0.05）. The VAS in repaired group was（2.5±0.6）points at 4 months after operation，significantly decreased in comparison with（3.2±1.2）points in non-repaired group（ P<0.05）. The VAS in repaired group was（2.0±1.4）points when compared to（2.2±1.3）points in non-repaired group at the last follow-up（ P>0.05）. The range of motion of joint flextion and extension in repaired group was（107.6±6.9）° and（125.9±7.8）° at 4 months after operation and at the last follow-up，significantly increased in comparison with（89.6±4.0）° and（120.9±5.2）° in non-repaired group（ P<0.05）. The medial opening distance in repaired group was（2.3±0.2）mm at the last follow-up，significantly decreased when compared to（3.1±0.2）mm in non-repaired group（ P<0.05）. Conclusion:For type KD-IIIM knee dislocation，arthroscopic anchor fixation of MCL or without MCL repair combined with anterior and posterior cruciate ligament reconstruction are both effective in satisfactory functional recovery，but MCL repair contributes to earlier function recovery，faster pain relief and more reliable joint stability.

Objective:To explore the mechanism of Dahuangfuzi decoction on intestinal motility disorder by observing its effect on serum motilin, Cajal interstitial cells and motilin receptor in rats with severe acute pancreatitis (SAP).Methods:Eighteen clean male Sprague-Dawley rats were randomly divided into the control group, SAP group and Dahuangfuzi group ( n=6 each group). The SAP rat model was prepared by retrogradely injected 4% sodium taurocholate into cholangiopancreatic duct. The rats in the SAP group were given 2 mL normal saline (37℃) enema at 12 and 24 h after operation. The rats in the Dahuangfuzi group was given 2 mL Dahuangfuzi decoction (37℃) enema at 12 and 24 h respectively. For the control group, the pancreas was exposed in the same way and then the abdomen was closed. Forty-eight h after operation, the abdominal aorta blood samples were taken for determination of serum endotoxin and amylase, and for detection of serum motilin by enzyme-linked immunosorbent assay (ELISA); the pathological changes of pancreas and ileum were observed by hematoxylin-eosin (HE) staining. The expression of c-kit and motilin receptor protein in ICC in ileum tissue was detected by immunohistochemistry. Results:Compared with the control group, the levels of serum endotoxin and amylase in the SAP group were significantly higher [(504.98±88.81) pg/mL vs. (17.76±5.01) pg/mL; (532.28±66.53) vs. (69.45±3.61) U/L, P<0.05], while the levels of serum motilin were significantly lower [(195.4±6.7) ng/L vs. (301±8.10) ng/L, P<0.05], and the scores of c-kit and motilin receptor protein were decreased ( P<0.05); compared with the SAP group, the levels of serum endotoxin and amylase in the Dahuangfuzi group were significantly reduced [(189.9±38.23) pg/mL vs. (504.98±88.81) pg/mL; (294.23±25.66) vs. (532.28±66.53) U/L, P<0.05], while the levels of serum motilin were significantly increased [(264.2±8.3) ng/L vs. (195.4±6.7) ng/L, P<0.05], and the scores of c-kit and motilin receptor protein were increased ( P<0.05). Conclusions:Dahuangfuzi decoction can improve the intestinal motility of SAP rats by promoting the secretion of motilin, increasing the activity of ICC cells and the expression of motilin receptor.

Correlations between content of linarin in Chrysanthemum indicum and climatic factors in habitats / 中国中药杂志

Chrysanthemi Indici Flos(CIF), the capitulum of Chrysanthemum indicum, is widely used in proprietary Chinese medicine and daily chemical products. At present, CIF is mainly produced from wild resources and rarely cultivated. This study aims to reveal the correlations between linarin content in CIF and climatic factors in different habitats, and provide a theoretical basis for suitable zoning and rational production of medicinal materials. The content of linarin in CIF was determined by HPLC. Grey relational analysis and Pearson correlation analysis were carried out for linarin content with climatic factors. The results showed that the content of linarin in CIF was significantly different among different habitats. The grey relational degrees of climatic factors with linarin content was in an order of average annual precipitation>annual average sunshine hours>annual average temperature>longitude>annual frost-free period>latitude>altitude. Longitude, annual average temperature and average annual precipitation had significantly positive correlations with the content of linarin in CIF, whereas latitude and altitude showed negative correlations with it. The annual frost-free period and annual average sunshine hours had no significant correlation with the content of linarin in CIF. The content of linarin in CIF varied significantly in different habitats. High longitude, low latitude, low altitude, high annual average temperature and high annual average precipitation could be used as indicators for the habitats of high-quality Ch. indicum. This study provides a reference for selecting suitable producing areas of Ch. indicum and establishing artificial cultivation system.

Anti-scarring effect of rapamycin following filtering surgery in rabbit eyes / 南方医科大学学报

OBJECTIVE@#To study the effect of rapamycin on scar formation in rabbit eyes following filtering operation and explore the possible mechanism.@*METHODS@#Ninety-six healthy adult rabbits were subjected to trabeculectomy of the left eye and subsequently randomly divided into 4 groups (=24) for treatment with castor oil (control) or rapamycin (1%, 3%, or 5%) eye drops of the operated eyes 4 times a day. The morphology and function of the filtering blebs of the rabbits were compared at 7, 14, 21 and 28 days after the operation; at each of the time points, 6 rabbits from each group were euthanized for detection of expressions of proliferating cell nuclear antigen (PCNA) and α-smooth muscle actin (α-SMA) in the tissues in the surgical area using immunohistochemistry. Cultured rabbit subconjunctival fibroblasts (RTFSs) were treated with different concentrations of rapamycin (0.06, 0.25, 1, and 4 mg/L) and the cell apoptosis was detected using flow cytometry.@*RESULTS@#In the first, second and third weeks after the operation, the rate of functional follicle formation was significantly higher in the 3 rapamycin groups than in the control group ( < 0.05), and the number of α- SMA-positive fibroblasts decreased over time in the 3 rapamycin groups. In cultured RTFSs, treatment with rapamycin at different concentrations resulted in increased apoptosis of the cells, and rapamycin above 0.25 mg/L significantly increased the cell apoptosis in a dose-dependent manner.@*CONCLUSIONS@#Rapamycin can inhibit hyperplasia of the filtering passage tissue, helps to preserve the functional filtering blebs and prolong their life span, and induces apoptosis of RTFS.

Objective To study the curative effects of jejunal exclusion surgery for STZ-induced T2DM SD rats.Methods 60 SD rats were induced to be the T2DM SD rats by intraperitoneal injection of streptozotocini.As a result,55 T2DM SD rats were successfully acquired which were randomly divided into 3 groups,20 rats in the jejunal exclusion group (A),20 rats in the sham operation group (B) and 15 rats in the control group (C).Jejunal exclusion surgery was performed in group A,jejunojejunostomy was performed in group B,and group C were fed normally.The body weight,fasting blood glucose,fasting plasma insuhn level and GLP-1 level were measured before operation and at the 1st,2rid,4th,8th and 16th week after operation.Results As compared with that before operation and that of the control group,the body weight in group A markedly declined at the 2nd,4th,8th and 16th week (352.14±9.00,342.84±8.90,336.64±10.26,330.34±9.12,P＜0.05).The fasting plasma glucose levels in group A markedly declined at the 2nd,4th,8th and 16th week (14.62±1.10,12.12±1.38,8.75± 1.06,7.55±1.00,P＜0.05).The fasting plasma insulin level in group A was maikedly increased at the 2nd,4th,8th and 16th week (14.62±3.10,16.12±3.38,17.75±4.06,17.55±3.10,P＜0.05).GLP-1 level in group A was markedly increased at the 1st,2nd,4th,8th and 16th week (11.02±0.85,14.42±1.18,16.02±1.59,17.62±1.02,18.12±0.71,P＜0.05).Conclusions The jejunal exclusion surgery is effective in controlling blood glucose,which is an ideal and lasting method.This surgery has also showed influence on body weight.

The Influence of Sex in Stroke Thrombolysis: A Systematic Review and Meta-Analysis

BACKGROUND AND PURPOSE: There is increasing recognition of the importance of stroke in females to both clinical and public health. The natural course of stroke is worse in females than in males, but the evidence regarding sex disparities in the responses to thrombolysis in stroke patents is still controversial. We compared outcomes after thrombolysis treatment between females and males. METHODS: Clinical trials reported in the Embase, PubMed, and Cochrane Library electronic databases up to March 13, 2017 were included in this analysis. Two reviewers independently extracted the data and conducted quality assessments. Statistical tests were performed to check for heterogeneity and publication bias. Sensitivity analysis was also performed to evaluate the stability of the conclusions. RESULTS: Sixteen reports involving 60,159 patients were available for analysis. The female patients were a 0.89-fold [95% confidence interval (CI)=0.87–0.90, p < 0.001], 0.89-fold (95% CI=0.87–0.91, p < 0.001), and 1.24-fold (95% CI=1.11–1.36, p < 0.001) more likely to obtain good, excellent, and poor functional outcomes, respectively, with no significant difference in the complications of symptomatic intracranial hemorrhage among the sexes [risk ratios (RR)=0.99, 95% CI=0.92–1.07, p=0.81] after thrombolysis treatment. In addition, the prevalence of a good functional outcome did not differ significantly between females and males in the intra-arterial thrombolysis (IAT) group (RR=1.05, 95% CI=0.85–1.29, p=0.67) in a subgroup analysis. CONCLUSIONS: This study has demonstrated that females often exhibit a worse outcome than males after intravenous thrombolysis (IVT), whereas no relevant sex differences were found in outcome or recanalization after IAT, with safety regarding hemorrhage complications from thrombolysis being the same for the sexes. However, IVT should not be withheld from female stroke patients solely based on their sex before the findings are confirmed in further large-scale research.

Anti-scarring effect of rapamycin in rabbits following glaucoma filtering surgery / 南方医科大学学报

OBJECTIVE@#To study the anti- scarring effect of rapamycin in rabbits receiving glaucoma filtering surgery.@*METHODS@#Ninety-six Chinchilla rabbits were randomized equally into 3 rapamycin treatment groups and one control group. All the rabbits underwent trabeculectomy, after which the rabbits in the 3 rapamycin groups were treated with eye drops containing 1%, 3%, or 5% rapamycin in the operated eyes, and those in the control groups were given castor oil 4 times a day. The intraocular pressure (IOP) and inflammatory reaction in the treated eyes were observed, and the PCNA-positive cells in the filtering bleb were detected using immunohistochemistry. RTFs isolated from the Tenon's capsule of the rabbits were cultured , and the expressions of caspase-3, caspase-8, and caspase-9 in the fibroblasts were detected after treatment with different concentrations of rapamycin.@*RESULTS@#The IOP was significantly lower in rapamycin-treated group than in the control group after the surgery ( < 0.05). The counts of the PCNA-positive cells were significantly lower in rapamycin-treated rabbits than in the control group ( < 0.05). Rapamycin treatment dose-dependently increased the expressions of caspase-3 and caspase- 9 at both the mRNA ( < 0.001) and protein ( < 0.001) levels without causing significant changes in the expressions of caspase-8.@*CONCLUSIONS@#Rapamycin can inhibit excessive proliferation of the fibroblasts in the filtering bleb to reduce scar formation after glaucoma filtration surgery in rabbits. Rapamycin also increases the expressions of caspase-3 and caspase-9 to induce apoptosis of the RTFs.

The expression and significance of protein AQP5 and CC16 in lung injury after hemorrhagic shock resuscitation in rats / 中华急诊医学杂志

Objective To observe the expression of protein AQP5 and CC16 in lung after hemorrhagic shock resuscitation in rats in order to explore the mechanism of acute lung injury.Methods Thirty-two healthy and clean male SD rats were randomly (random number) divided into two groups:control group and hemorrhagic shock resuscitation group (n =16 in each).Besides,each group was further divided into two subgroups according to the experiment done at 12 h and 24 h after hemorrhagic shock resuscitation (n =8).The hemorrhagic shock model was made by using Wiggers' modified method.Resuscitation was done by transfusing the autologous blood and the equal volume of Ringer's solution.Blood samples were obtained from abdominal aorta at each given interval to measure the level of plasma endotoxin,and assay the CC16 and AQP5 by using ELISA.After the rats were sacrificed,the left lung tissue was taken to measure lung water content and the dry/wet ratio,and to examine the levels of CC16 and AQP5 in lung tissue by immunohistochemical method.Results ①The level of plasma endotoxin in the experimental group was significantly higher than that in the control group (P ＜ 0.01).②The content of plasma CC16 in the experimental group was higher than that in the control group (P ＜ 0.05).③Compared with the control group,the content of pulmonary homogenate AQP5 in the experimental group was significantly lower (P ＜0.05).④The lung water content (the dry/wet ratio) of the experimental group was obviously higher than that of the control group (P ＜ 0.05).⑤Hislogogical observation with HE staining showed in the control group,the alveolar structure was complete,the alveolar sacs were clear,and the alveolar septum was intact;but in the experimental group,the alveolar septum was widened,and there were obvious hemorrhage and neutrophil infiltration in the alveolar space.⑥ The level of lung tissue CC16 in control group was significantly higher compared with experimental group (P ＜ 0.05).⑦ The level of lung tissue AQP5 was significantly higher in control group compared with experimental group (P ＜ 0.05).Conclusions The proteins of AQP5 and CC16 were involved in the process of acute lung injury after hemorrhagic shock resuscitation in rats,and their levels were positively correlated with length of time after hemorrhagic shock.

Susceptibility-weighted Imaging in Thrombolytic Therapy of Acute Ischemic Stroke / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>To provide a comprehensive and latest overview of susceptibility-weighted imaging (SWI) in the application of thrombolysis in acute ischemic stroke, and to update the decision-making effect and clinical value of SWI on identifying stroke patients suitable for thrombolytic therapy and possible benefits and risks followed.</p><p><b>DATA SOURCES</b>Literatures referred to this review were collected from PubMed, Medline, and EMBASE published till May 2017, using the search terms including susceptibility-weighted imaging, gradient-echo, T2*, thrombolysis, recombinant tissue plasminogen activator (rt-PA), thrombolytic therapy, and stroke.</p><p><b>STUDY SELECTION</b>Papers in English or with available English abstracts were considered, with no limitation of study design. References were also identified from the bibliographies of identified articles and the authors' files.</p><p><b>RESULTS</b>SWI is of guiding significance for thrombolytic therapy in stroke patients, it can predict the location and length of thrombus and ischemic penumbra. It is worthy of noting that susceptibility vessel sign (SVS) on SWI can be used to predict recanalization after thrombolytic therapy and whether it is better to implement endovascular thrombolectomy in combination or alone. SWI is sensitive in detecting cerebral microbleed (CMB), and CMB might not be a contraindication for thrombolytic therapy, yet CMBs in multiple foci could possibly be related to intracranial hemorrhage (ICH) after thrombolysis. SVS and CMB on SWI sequence are of instructive value in performing antiplatelet therapy after thrombolytic therapy. Cerebral venous change on SWI is related to lower recanalization rate and poor outcome after thrombolysis.</p><p><b>CONCLUSIONS</b>It seems that SWI can be applied to guide individualized thrombolytic therapies and assist clinicians in making better decisions by weighing benefits and risks. However, there still exist controversies about the relationship between signs on SWI and thrombolytic therapy.</p>

Relationship between Apolipoprotein Superfamily and Parkinson's Disease / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>Parkinson's disease (PD) is featured with motor disorder and nonmotor manifestations including psychological symptoms, autonomic nervous system dysfunction, and paresthesia, which results in great inconvenience to the patients' life. The apolipoprotein (Apo) superfamily, as a group of potentially modifiable biomarkers in clinical practice, is of increasing significance in the diagnosis, evaluation, and prognosis of PD. The present review summarized the current understanding and emerging findings of the relationship between Apo superfamily and PD.</p><p><b>DATA SOURCES</b>All literatures were identified by systematically searching PubMed, Embase, and Cochrane electronic databases with terms "Parkinson disease," "apolipoprotein," and their synonyms until May 2017.</p><p><b>STUDY SELECTION</b>We have thoroughly examined titles and abstracts of all the literatures that met our search strategy and the full text if the research is identified or not so definite. Reference lists of retrieved articles were also scrutinized for additional relevant studies.</p><p><b>RESULTS</b>The levels of plasma ApoA1 are inversely correlated with the risk of PD and the lower levels of ApoA1 trend toward association with poorer motor performance. Higher ApoD expression in neurons represents more puissant protection against PD, which is critical in delaying the neurodegeneration process of PD. It is suggested that APOE alleles are related to development and progression of cognitive decline and age of PD onset, but conclusions are not completely identical, which may be attributed to different ApoE isoforms. APOJ gene expressions are upregulated in PD patients and it is possible that high ApoJ level is an indicator of PD dementia and correlates with specific phenotypic variations in PD.</p><p><b>CONCLUSIONS</b>The Apo superfamily has been proved to be closely involved in the initiation, progression, and prognosis of PD. Apos and their genes are of great value in predicting the susceptibility of PD and hopeful to become the target of medical intervention to prevent the onset of PD or slow down the progress. Therefore, further large-scale studies are warranted to elucidate the precise mechanisms of Apos in PD.</p>

Objective To investigate the influence of early enteral nutrition therapy on the intestinal barrier function and immune response of the patients with radiation enteritis (ER) so as to find a relatively simple and effective method to treat RE.Methods Fifty-six patients with radiation enteritis (RE) diagnosed by colonoscopy,X-rays,and pathology were randomly divided into 2 equal groups:experimental group undergoing enteral inutrition therapy,and control group undergoing conventional therapy only.Peripheral blood samples were collected 1,11,and 21 days after admission.Plasma diamine oxidase (DAO),D-lactic acid,endotoxin,and lactulose/mannitol (L/M) ratio,and levels of IgG,IgM,and IgA,and CD4/CD8 ratio were examined.Five cases from the experimental group and 5 cases from the control group underwent second-time operation because of incomplete intestinal obstruction,intestinal stenosis,or recurrent tumor respectively.The biopsy specimens of the terminal ileum or distal descending colon taken during the first and second operations underwent pathological examination.Peripheral blood samples were collected 1,11,and 21 days after admission.Plasma diamine oxidase (DAO),D-lactic acid,endotoxin,and lactulose/mannitol (L/M) ratio,and levels of IgG,IgM,and IgA,and CD4/CD8 ratio were examined.Results There were no significant differences in the intestinal function and blood immunological indices between these 2 groups.The levels of DAO,D-lactic acid,and endotoxin,and the L/M ratio 11 days after admission of the experiment group were all significantly lower than those of the control group (t =2.568,2.427,2.143,2.443,P ＜ 0.05),and all those indices 21 days after admission of the experiment group were all much more significantly lower in comparison with the control group (t =6.019,12.834,7.837,7.997,P ＜ 0.01).The levels of IgG,IgM,and IgA,and CD4/CD8 ratio 11 days after admission of the experimental group were all significantly higher than those of the control group (t =2.096,2.211,2.182,P＜ 0.05,and t=2.301,P＜ 0.05),and the differences became much more significant 21 days after admission (t =2.703,2.679,3.138,P ＜ 0.01,and t =5.107,P ＜ 0.01).The height of the intestinal villa and the thickness of the mucosa of the specimens taken at the second-time operation were both much greater than those at the first-time operation.Conclusion Early enteral support therapy helps effectively maintain the intestinal barrier and immune response function of the RE patients.

Women boxing athletes' EMG of upper limbs and lumbar muscles in the training of air striking of straight punch / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To study training effect of upper limbs and lumbar muscles in the proceed of air striking of straight punch by analyzing boxing athletes' changes of electromyogram (EMG).</p><p><b>METHODS</b>We measured EMG of ten women boxing athletes' upper arm biceps (contractor muscle), upper arm triceps (antagonistic muscle), forearm flexor muscle (contractor muscle), forearm extensor muscle (antagonistic muscle), and lumbar muscles by ME6000 (Mega Electronics Ltd.). The stipulated exercise was to do air striking of straight punch with loads of 2.5 kg of dumbbell in the hand until exhausted.</p><p><b>RESULTS</b>In the proceed of exercise-induce exhausted, the descend magnitude and speed of median frequency (MF) in upper limb antagonistic muscle exceeded to contracting muscle, moreover, the work percentage showed that contractor have done a larger percentage of work than antagonistic muscle. Compared with world champion's EMG, the majority of ordinary athletes' lumbar muscles MF revealed non-drop tendency, and the work percentage showed that lumbar muscles had a very little percentage of work.</p><p><b>CONCLUSION</b>After comparing the EMG test index in upper limb and lumbar muscle of average boxing athletes with that of the world champion, we find the testees lack of the training of upper limb antagonistic muscle and lumbar muscle, and more trainings aimed at these muscles need to be taken.</p>

Protective effects of Dahuangfuzi decoction on the intestine barrier functional of acute necrotizing pancreatitis in rats / 中华胰腺病杂志

Objective To observe the effects of Dahuangfuzi decoction on the intestine barrier functional of acute necrotizing pancreatitis in rats. Methods The 60 rats were randomly divided into sham operation group ( n = 19 ), ANP group ( n = 21 ), and Dahuangfuzi treatment group ( n = 20). The rats of ANP group were induced by injecting 1 ml/kg of 4% sodium taurocholate into the pancreatiobiliary duct, and jejunal fistula was esablished. The rats of treatment group received Dahuangfuzi decoction (2 ml, repeated at 4 and 8 h)through jejunum distal stoma tube 0. 5 h after ANP induction. The other 2 groups received same amount of normal saline. Blood sample was collected through abdominal aorta, 24 h after ANP induction, and the serum amylase, endotoxin, D-lactate, plasma diamine oxidase (DAO) were detected. Pancreas, small intestine tissue was harvested for pathologic examination, index of intestinal epithelial damage was measured and ultrastructural changes in small intestinal mucosa was observed. Results The expression of serum amylase, endotoxin,D-lactate, DAO in sham operation group was ( 152 ± 32 ) U/L, (6.95 ± 2.10) pg/L, ( 3.96 ± 1.08 ) μg/mland ( 14.26 ± 2.67 ) μg/ml, while the corresponding values were ( 1549 ± 93 ) U/L, (40.48 ± 3.41 ) pg/L,( 12.34 ± 1.23 ) μg/ml and ( 80.28 ± 3.54) μg/ml in ANP group, and they were (655 ± 49 ) U/L, ( 19.55 ±2.50) pg/L, (6.75 ± 1.36 ) μg/mland ( 20.69 ± 7.53 ) μg/ml in treatment group. The values in ANP group were significantly higher than those in sham operation group. The values in treatment group were significantly lower than those in ANP group, but significantly higher than those in sham operation group ( P ＜ 0.05 or P ＜0. 01 ). The thickness and height of intestinal mucosa in ANP group were ( 389.44 ± 29.87 )μm and ( 16.52 ±3.73) μm, which were significantly lower than those in treatment group [(501.95 ± 45.38 )μm, (27.82 ±5.17)] μm, and in sham operation group [( 658.72 ± 57.49 ) μm, ( 35.49 ± 6.43 )μm, Index of intestional epitholial donage in ANP group was 3.72 ± 0.65 which is significently higher than those in theatment (2.12 ±0.37 ) and in sham operation group (0.85 ± 0.24). The intestinal mucosa histological and ultrastructural changes in Dahuangfuzi treatment group were better than those in ANP group. Conclusions Dahuangfuzidecoction can significantly decrease the damage of intestine barrier function in ANP rats.
