ABSTRACT

Objective:To investigate the influence of preoperative thyroid dysfunction on the 30-day postoperative mortality and complications in elderly patients with hip fracture.Methods:A retrospective analysis was conducted of the 349 elderly patients with hip fracture who had been admitted to Department of Orthopedic Trauma, Beijing Luhe Hospital Affiliated to Capital Medical University from January 2018 to December 2019. They were 108 males and 241 females, with an average age of 76.3 years (from 60 to 104 years). There were 190 femoral intertrochanteric fractures and 159 femoral neck fractures. By the preoperative level of thyroid function, the patients were divided into a normal function group of 290 cases and a dysfunction group of 59 cases. The 2 groups were compared in terms of hospital stay, mortality and incidence of complications within 30 days postoperation.Results:In this cohort, the rate of 30-day postoperative mortality was 3.4%(12/349) and the incidence of 30-day postoperative complications 14.6%(51/349). The 2 groups were comparable because there was no significant difference between them in the preoperative general data except for the preoperative comorbidity of coronary heart disease ( P>0.05). In the dysfunction group, the hospital stay averaged (10.2±6.9) d, the rate of 30-d postoperative mortality 1.7%(1/59) and the incidence of 30-day postoperative complications 16.9%(10/59), which were insignificantly different from those in the normal function group [(10.7±7.5) d, 3.8%(11/290) and 14.1%(41/290), respectively] ( P> 0.05). Conclusion:Since preoperative thyroid dysfunction does not affect the 30-day postoperative mortality and postoperative complications in the elderly patients with hip fracture but no definite thyroid disease, routine thyroid function screening is not recommended for them.

ABSTRACT

The construction of brain functional network based on resting-state functional magnetic resonance imaging (fMRI) is an effective method to reveal the mechanism of human brain operation, but the common brain functional network generally contains a lot of noise, which leads to wrong analysis results. In this paper, the least absolute shrinkage and selection operator (LASSO) model in compressed sensing is used to reconstruct the brain functional network. This model uses the sparsity of

ABSTRACT

Objective@#To study the incidence and clinicopathological features of intermediate fibroblastic/myofibroblastic tumors(IF/MFT) in infants and the young children.@*Methods@#All available cases with soft tissue tumors in infants and children were retrieved from the files of Women and Children′s Hospital Affiliated to Qingdao University, from January 2012 to December 2017.The incidence rate of IF/MFT was observed.Cases of IF/MFT were identified and investigated by light microscopy and immunohistochemistry by reviewing the related literature.@*Results@#Among 290 soft tissue tumors, 15 cases(5.2%) were IF/MFT, accounted for 88.2%(15/17 cases) of borderline soft tissue tumors.Twelve cases were male, 3 cases were female, the median age was 8 months, and 4 cases were congenital.Clinically, 11 cases were presented with slow-growing painless masses located in the trunk or extremities.According to histopathology, 9 cases(60.0%) were categorized as infantile fibromatosis(IFM), including 5 cases(33.3%) desmoid-type and 4 cases(26.7%) diffuse-type; 3 cases(20.0%) as lipofibromatosis(LFM); 2 cases(13.3%) as infantile fibrosarcoma(IFS) and 1 case(6.7%) as giant cell fibroblastoma(GCF). All 15 tumors were characterized by the presence of spindle fibroblasts and myofibroblasts with infiltration of the surrounding structures.Immunohistochemically, all the 15 cases were diffusely positive for Vimentin(Vim), but negative for Myogenin, MyoD1, Desmin and S-100.Smooth muscle actin(SMA), β-catenin and Bcl-2 were positive in some cases to a certain degree.The Ki-67 proliferation index was higher in diffuse-type IFM and IFS, the former was 5.0%-20.0%, and the latter was about 20.0%, however, the other cases showed Ki-67 <5.0%.The main clinical treatment was complete or extensive excision.@*Conclusions@#IF/MFT accounts for a high proportion of intermediate soft tissue tumors in infants and young children, mostly seen in male children, and IFM and LFM are the main types.The clinical signs and symptoms associated with these tumors are often nonspecific, and their histopathologic manifestations may overlap.The final diagnosis of IF/MFT must depend on the characteristics of age, location, histopathologic changes and immunohistoche-mical findings.

ABSTRACT

Objective To explore the relationship between the status of HBsAg-positive infection of mothers and the non/low-response to hepatitis B vaccine of their infants.Methods A total of 225 pairs of mothers and their infants were recruited in our cohort from June 2011 to July 2013.Infants were given three doses of hepatitis B vaccine at hour 24,first month and month 6th respectively and were followed up for one year after birth.HBV serological markers and HBV DNA in the peripheral blood of both mothers and infants were detected by Electro-chemiluminescence immunoassay and fluorescence quantitative Polymerase Chain Reaction.Results Six HBV infection models were detected in HBsAg-positive mothers,and "HBsAg (+),HBeAg (+),anti-HBc (+)" (model one) and "HBsAg (+),anti-HBe (+),anti-HBc (+)" (model two) accounted for 92.5% (208/225) of all the models.Rate of non/low-response to hepatitis B vaccine in infants born to mothers in model one was lower than those in model two,the differences are statistically significant (x2=4.80,P=0.029).The rate of non/low-response to hepatitis B vaccine in infants showed a downward trend with the rising of HBeAg level in their mothers (x2=4.86,P=0.028).Results from the unconditional logistic regression analysis showed that the HBeAg of the HBsAg-positive mothers was significantly correlated with the low risk of non/low-response to hepatitis B vaccine in infants (OR=0.598,95%CI:0.378-0.947).The positive rate of serum HBV DNA in HBsAg-positive mothers was 54.2%,while the rate of non/low-response to hepatitis B vaccine in infants born to HBV DNA positive mothers was similar to those infants born to HBV DNA negative mothers (X2=0.22,P=0.640).Conclusions "HBsAg (+),HBeAg (+),anti-HBc (+)" and "HBsAg (+),anti-HBe(+),anti-HBc (+)" were the common models seen in HBsAg-positive mothers,and the rate of non/low-response to hepatitis B vaccine was different between the two models.HBeAg of HBsAg-positive mothers might have positive effects on the immune response to hepatitis B vaccine in infants but the mechanisms remained not clear.HBV DNA of the HBsAg-positive mothers did not seem to be correlated with the immune response to hepatitis B vaccine in infants.

ABSTRACT

The Bcr-Abl oncogene is produced by the reciprocal translocation between c-Abl gene on chromosome 9 and the Bcr gene on chromosome 22 in human genome. The encoded Bcr-Abl fusion protein is responsible for the pathogenesis of certain human leukemias. Abelson murine leukemia virus (A-MuLV) is a retrovirus that could lead to transformation of B lymphocyte in mice, and v-Abl is the oncogene of A-MuLV. Abl oncoproteins (such as Bcr-Abl and v-Abl) play critical roles in tumorigenesis of certain cell types. Several signal transduction pathways, including JAK/STAT/Pim, PI3K/AKT/mTOR and RAS/RAF/MEK signaling pathway, are involved in Abl-mediated tumorigenesis. In addition, Abl-mediated tumorigenesis is associated with mutation or abnormal modification of key signal molecules as well as dysregulation of some critical long noncoding RNAs (lncRNAs). Here, we review the molecular mechanisms by which Abl oncogenes activate three major signaling pathways, and provide a scientific basis for therapy of Abl oncoprotein-induced tumors.

ABSTRACT

Objective To determine the effects of delayed umbilical cord clamping on the postpartum hemorrhage,instant and long-term newborn anemia,newborn jaundice.Methods In total,303 infants were selected during October 2016 to June 2017 in three hospitals in Beijing.They were randomly allocated into two groups receiving instant clamping of umbilical cord (less than 60s after delivery,n=158) and delayed clamping of umbilical cord(after cord pulsation ceased,n=145).Relevant indicators of maternal and neonatal outcomes are compared.Results There were significant differences between two groups in instant hemoglobin concentration and in 5~7 days (P<0.05).There were no differences between two groups in transcutaneous bilirubin,the risk of anemia in three months,the risk of jaundice in 5~7 days and the need of blue-light therapy (P>0.05).There were no differences between two groups of women in postpartum hemorrhage,the length of third stage of labor and the rate of breast feeding (P>0.05).Conclusion Clamping the umbilical cord when cord pulsation has ceased does not have negative effects on delivery process and postpartum hemorrhage,but it increases the instant hemoglobin concentration and hemoglobin concentration after delivery in 5~7 days.Still it is unclear whether it will affect the risk of jaundice.

ABSTRACT

Objective To explore the relationship between HBeAg in HBsAg positive mothers and CD4 + CD25 + Foxp3 + regulatory T cells (Treg) in newborns,as well as how they would influence the increasing risk on HBV intrauterine transmission.Methods We collected information on general demographic characteristics and delivery on 270 HBsAg positive mothers and their newborns from the Third People's Hospital of Taiyuan.Fluorescence quantitative polymerase chain reaction (FQ-PCR) and chemiluminescence immunoassay (CLIA) were used to detect HBV DNA and HBV serological markers in peripheral blood from both mothers and neonates.The expression of Treg and other immune cells in peripheral blood of neonates were detected with flow cytometry (FCM).Results Maternal HBeAg positive rates were associated with an increased risk of intrauterine transmission (0R=4.08,95% CI:1.89-8.82).Rates of T.reg in newborns born to HBsAg-positive mothers were higher than that of the negative group (Z=2.29,P=0.022).Each pair of the subjects was assigned to five different groups according to the HBeAg titers of mothers.Frequencies of both Treg and HBeAg in newboms and HBV DNA in mothers between the above said 5 groups showed similar trends of changing patterns and the differences between groups were statistically significant (x2=18.73,P<0.001;x2=181.60,P<0.001;x2=183.09,P<0.001).Results from partial correlation analysis showed that after adjusting for neonatal HBeAg and maternal HBV DNA,mother's HBeAg titers were positively related to the percentage of Treg in their newboms (rs=0.19,P=0.039).In addition,the frequencies of Treg were negatively correlated with pDC and CD4 + T cell in their newborns (rs=-0.21,P=0.017;r,=-0.23,P=0.009).Conclusion HBeAg from HBsAg positive mothers might have inhibited the function of neonatal DC cells and T cells to reduce the immune response to HBV by up-regulating the proportion of Treg and finally increased the risk of HBV intrauterine transmission.

ABSTRACT

Objective To explore the effect of interleukin-6 (IL-6) and Interleukin-12(IL-12) on immune response to hepatitis B vaccination in infants of HBsAg-positive mothers.Methods A total of 91 neonates whose mothers were HBsAg-positive were included and followed up for 12 months.HBV DNA and HBV serological markers in the peripheral blood of the neonates and infants were detected with fluorescence quantitative polymerase chain reaction (FQ-PCR) and chemiluminescence immunoassay (CLIA),and the levels of IL-6 and IL-12 in the peripheral blood of the neonates and infants were detected with enzyme-linked immunosorbent assay (ELISA).Results The non-/hypo-response rate to hepatitis B vaccination was 35.16% (32/91) in the 91 infants.In the neonatal period and infantile period,the level of IL-6 in non-/hypo-response group was lower than that in high-response group,while the level of IL-12 was higher than that in high-response group,and there was significant difference (P<0.01).From the neonatal period to the infantile period,the level of IL-6 increased,while the level of IL-12 descended in both groups,and there was significant difference (P<0.01).Furthermore,the level of anti-HBs of infants was positively correlated with the level of IL-6 (rs =0.70,0.79,P< 0.01),and was negatively correlated with the level of IL-12 (rs=-0.71,-0.72,P<0.01) in the neonatal period and the infantile period.From the neonatal period to the infantile period,the increased level of IL-6 was positively associated with the level of anti-HBs (rs =-0.74,P<0.01),while the decreased level of IL-12 was negatively associated with the level of anti-HBs (rs=-0.42,P<0.01).The level of IL-6 was negatively correlated with the level of IL-12 in the neonatal period and the infantile period (rs=-0.68,-0.70,P<0.01).Conclusions IL-6 might promote the immune response to hepatitis B vaccination in infants whose mothers were HBsAg-positive,while IL-12 might inhibit the immune response.IL-6 and IL-12 would affect the immune response to hepatitis B vaccination in infants of HBsAg-positive mothers at the same time.

ABSTRACT

Objective To investigate the influencing factors for non/low-response to hepatitis B vaccine in infants of HBsAg-positive mothers.Methods A total of 286 HBsAg-positive pregnant women and their infants were recruited from the Third People's Hospital of Taiyuan during July 2011 to January 2013.The infants were immunized with hepatitis B vaccine according to the 0-1-6 month vaccination schedule and followed up for 12 months.The serum HBV DNA level of mothers,neonates and infants were detected by electro chemilum inescence immunoassay kits and fluorescene quantiative polymerase chain rection.Results Among 286 infants,the rate of non/low-response to hepatitis B vaccine was 18.53% (53/286).Non-conditional logistic regression analysis indicated that the mother's HBV DNA level ≥ 1 × 107 copies/ml (0R=2.592,95%CI:1.121-5.996) and natural birth (OR=1.932,95%CI:1.021-3.654) were the risk factors for non/low-response to hepatitis B vaccine,the risks were 2.592 times and 1.932 times higher compared with the infants whose mothers were HBV DNA negative and the infants whose mothers had cesarean delivery.There was no multiplicative or additive interaction between high HBV DNA load and natural birth (OR=1.055,95%CI:0.209-5.321),(RERI=1.617,95%CI:-4.038-7.272;AP=0.364,95%CI:-).527-1.225;SI=1.195,95%CI:0.270-13.135).After stratified analysis of mother's HBV DNA level,delivery mode of mothers was not associated with non/low-response of their infants.Conclusion The mother's load of HBV DNA ≥ 1 × 107 copies/ml might be the factor for non/low-response to hepatitis B vaccine in infants of HBsAg positive mothers.

ABSTRACT

<p><b>OBJECTIVE</b>To establish an evaluation model of peritoneal metastasis in gastric cancer, and to assess its clinical significance.</p><p><b>METHODS</b>Clinical and pathologic data of the consecutive cases of gastric cancer admitted between April 2015 and December 2015 in Department of General Surgery, Zhongshan Hospital of Fudan University were analyzed retrospectively. A total of 710 patients were enrolled in the study after 18 patients with other distant metastasis were excluded. The correlations between peritoneal metastasis and different factors were studied through univariate (Pearson's test or Fisher's exact test) and multivariate analyses (Binary Logistic regression). Independent predictable factors for peritoneal metastasis were combined to establish a risk evaluation model (nomogram). The nomogram was created with R software using the 'rms' package. In the nomogram, each factor had different scores, and every patient could have a total score by adding all the scores of each factor. A higher total score represented higher risk of peritoneal metastasis. Receiver operating characteristic (ROC) curve analysis was used to compare the sensitivity and specificity of the established nomogram. Delong. Delong. Clarke-Pearson test was used to compare the difference of the area under the curve (AUC). The cut-off value was determined by the AUC, when the ROC curve had the biggest AUC, the model had the best sensitivity and specificity.</p><p><b>RESULTS</b>Among 710 patients, 47 patients had peritoneal metastasis (6.6%), including 30 male (30/506, 5.9%) and 17 female (17/204, 8.3%); 31 were ≥ 60 years old (31/429, 7.2%); 38 had tumor ≥ 3 cm(38/461, 8.2%). Lauren classification indicated that 2 patients were intestinal type(2/245, 0.8%), 8 patients were mixed type(8/208, 3.8%), 11 patients were diffuse type(11/142, 7.7%), and others had no associated data. CA19-9 of 13 patients was ≥ 37 kU/L(13/61, 21.3%); CA125 of 11 patients was ≥ 35 kU/L(11/36, 30.6%); CA72-4 of 11 patients was ≥ 10 kU/L(11/39, 28.2%). Neutrophil/lymphocyte ratio (NLR) of 26 patients was ≥ 2.37(26/231, 11.3%). Multivariate analysis showed that Lauren classification (HR=8.95, 95%CI:1.32-60.59, P=0.025), CA125(HR=17.45, 95%CI:5.54-54.89, P=0.001), CA72-4(HR=20.06, 95%CI:5.05-79.68, P=0.001), and NLR (HR=4.16, 95%CI:1.17-14.75, P=0.032) were independent risk factors of peritoneal metastasis in gastric cancer. In the nomogram, the highest score was 241, including diffuse or mixed Lauren classification (54 score), CA125 ≥ 35 kU/L (66 score), CA72-4 ≥ 10 kU/L (100 score), and NLR ≥ 2.37 (21 score), which represented a highest risk of peritoneal metastasis (more than 90%). The AUC of nomogram was 0.912, which was superior than any single variable (AUC of Lauren classification: 0.678; AUC of CA125: 0.720; AUC of CA72-4: 0.792; AUC of NLR: 0.613, all P=0.000). The total score of nomogram increased according to the TNM stage, and was highest in the peritoneal metastasis group (F=49.1, P=0.000). When the cut-off value calculated by ROC analysis was set at 140, the model could best balanced the sensitivity (0.79) and the specificity (0.87). Only 5% of patients had peritoneal metastasis when their nomogram scores were lower than 140, while 58% of patients had peritoneal metastasis when their scores were ≥ 140(χ=69.1, P=0.000).</p><p><b>CONCLUSION</b>The risk evaluation model established with Lauren classification, CA125, CA72-4 and NLR can effectively predict the risk of peritoneal metastasis in gastric cancer, and provide the reference to preoperative staging and choice of therapeutic strategy.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To assess the clinical value of the diagnostic laparoscopy in choosing treatment strategies for patients with gastric cancer.</p><p><b>METHODS</b>Retrospective analysis was performed on clinical and pathological data collected from 2 023 patients undergoing gastric cancer surgery in the Zhongshan Hospital of Fudan University from 2009 to 2014. All the patients were diagnosed as gastric cancer by endoscopic biopsy and staged by imaging examination before surgery. During the diagnostic laparoscopy procedure, a small periumbilical incision was made and a pneumoperitoneum with COunder 10-15 mmHg was established through a port. A 10 mm trocar was put in, and the camera was inserted. Two 5 mm trocars were put in two ports which located in midclavicular line two fingers under the left and right costal margin and then the instruments were inserted. A thorough inspection included ascites, the abdominal cavity, liver, diaphragm, spleen, greater omentum, colon, small intestine, mesentery, adnexa (female) and pelvic floor. If the tumor located at the posterior part of the stomach, the gastrocolic ligament was opened in order to look for carcinomatosis in the omental bursa. The accuracy rate of diagnostic laparoscopy in diagnosing adjacent organ invasion and intra-abdominal metastasis was calculated, and the rate of adjusting treatment plans after diagnostic laparoscopy was also calculated.</p><p><b>RESULTS</b>There were 52.7%(1 067/2 023) of patients underwent diagnostic laparoscopy. The accuracy rate of diagnostic laparoscopy in evaluating adjacent organ invasion and intra-abdominal metastasis were 98.3%(1 049/1 067) and 98.1%(1 047/1 067) respectively. Besides, 14 patients with stage T4b and 32 with intra-abdominal metastasis, which were missed by imaging examination, were diagnosed by diagnostic laparoscopy. The treatment plans of 9.3% (99/1 067) of patients were changed after diagnostic laparoscopy, and 65 (6.1%) cases of non-therapeutic laparotomy were avoided. However, 18 cases of adjacent organ invasion and 20 cases of intra-abdominal metastasis were still missed by diagnostic laparoscopy, and 12 cases received non-therapeutic laparotomy.</p><p><b>CONCLUSION</b>Diagnostic laparoscopy has considerable value in assessing adjacent organ invasion and intra-abdominal metastasis and has great clinical significance in making precise treatment plans.</p>

ABSTRACT

Background and Objective: Trimetazidine has mainly been used in coronary insufficiency, angina and elderly myocardial infarction. However, the effect of trimetazidine on the efficacy, heart rate variability [HRV] and protection of myocardial ischemia in elderly patients with acute coronary syndrome [ACS] remains unclear. This study aimed to investigate the effect of trimetazidine on the efficacy HRV and protection of myocardial ischemia in patients with ACS


Methods: One hundred twenty two elderly ACS patients who were above 70 years were chosen and randomly divided into two groups. One group was given conventional therapy, such as aspirin, isosorbide mononitrate and fluvastatin, and the other group was administered trimetazidine in addition to conventional therapy. The treatment period was eight weeks. A PI-2.22B three-channel AECG system was used on every patient for 24 hour dynamic electrocardiogram monitoring and HRV analyses on the first day after admission and eight weeks after treatment. HRV, 24 hour RR intermediate stage standard deviation [SDNN], five minutes average normal cardiac cycle standard deviation in 24 hour [SDANN], 24 hour close together normal cardiac cycle difference value mean square root [rMSSD], the percentage of difference of close together RR intermediate > 50 ms account total RR intermediate [PNN50], high frequency [HF] and low frequency [LF] parameters of patients were observed before and after treatment


Results: The SDNN, SDANN, rMSSD, PNN50 and HF parameters significantly increased compared with the conventional treatment group [all P < 0.05]. LF and LF/HF were significantly decreased in the trimetazidine treatment group compared with those in the conventional treatment group [all P < 0.05]


Conclusion: Trimetazidine improves HRV of elderly ACS patients and reduces cardiovascular events

ABSTRACT

Aims To study single dose toxicity of poly-phenols effective parts from Punica granatum,to eval-uate their safety,and thus to provide a theoretical basis for drug development and clinical use.To observe their protective effect on ethanol-induced gastric ulcer in rats.Methods 50 healthy Kunming mice were ran-domly divided into five groups and given different doses of polyphenols’effective parts from Punica granatum via intragastric administration.Toxicity and death in each group of mice were observed and recorded after administration for 14 d.The median lethal dose was calculated by Bliss method.70 rats were randomly di-vided into normal group,model group(constant volume of normal saline),sanjiuweitai particles(1 850 mg· kg-1 )group,colloidal bismuth subcitrate (33 mg · kg-1 )group and polyphenols effective parts from Puni-ca granatum low-dose,medium-dose,high-dose(430, 852,1 704 mg·kg-1 )groups.On the 9th day of 10 days’gavage,all except the normal group were fed ethanol (1.5 mL/only)to induce gastric mucosal inju-ry in rats with acute gastric ulcer.Gastric ulcer index, the rate of ulcer inhibition were calculated for each group.The morphological changes of gastric mucosa were observed.The gastric mucosa levels of PGE2 , NO,SOD and MDA were determined.Results The LD50 and 95%confidence limit of the polyphenols’ef-fective parts from Punica granatum were 8 520.9 mg· kg-1 and 7 291.2 ~9 914.4 mg·kg-1,respectively. Pathology showed that the organs receiving dose of 16 000 mg · kg-1 had different degrees of damage . Compared with the model group,the extract from Puni-ca granatum significantly repaired the gastric mucosa, and significantly increased the gastric mucosa levels of NO and reduced MDA content,and improved SOD content and the levels of PGE2 .Conclousion The dose of 5 063 mg · kg-1 of polyphenols effective part from Punica granatum showed no death.The dose of 16 000 mg · kg-1 of polyphenols effective parts from Punica granatum could cause varying degrees of dam-age in heart,liver,lung,kidney or the death of mice. The LD50 and 95% confidence limit of the polyphenols effective parts from Punica granatum were 8 520.9 mg ·kg-1 and 7 291.2 ~9 914.4 mg·kg-1,respective-ly.The extract from Punica granatum plays a protective role against gastric mucosa damage induced by absolute ethanol,and the mechanism may be related to promo-ting ulcer epithelial cells synthesis,enhancing mucosal regeneration function,regulating NO content and en-hancing antioxidant capacity.

ABSTRACT

Aim To study the activity and mechanism of inhibition of myocardial hypertrophy of total fla-vonoids of Cydonia oblonga Mill. in spontaneously hy-pertensive rats ( SHR) . Methods Total flavonoids of COM ( COMF) were separated and purified by the op-timal process. SHR were divided into 6 groups: SHR control group ( SHR) , captopril group ( SHR+CAP, 25 μg·g-1 ) , Eucommia ulmoides Oliver group ( SHR+EUO, 30 μg·g-1 ) , low ( SHR+COMF-L, 40 μg ·g-1 ) , middle ( SHR+COMF-M, 80 μg·g-1 ) and high dose ( SHR+COMF-H, 160 μg·g-1 ) of COMF groups. Wistar-Kyoto (WKY) rats (n=8) were given distilled water as control. The drugs were given by in-tragastric administration for 16 weeks. The histological and pathological examinations of the heart were per-formed and organic damage was valued. The levels of AngⅡand ALD in blood and heart were evaluated. The mRNA and protein expression of ACE, ACE2 and AT1 was determined by RT-PCR and Western blot to e-valuate the effect of COMF on RAAS. Results Com-pared with SHR control group, HW, HW/BW, LVM and LVM/BW decreased in SHR+COMF-M and SHR+COMF-H groups. Cadiomyocyte hypertrophy was in-hibited in COMF groups. The concentration of AngⅡand ALD in heart and blood decreased. ACE and AT1 mRNA and protein expression in heart tissue de-creased, while ACE2 mRNA expression increased ( P<0. 01 or P <0. 05 ) , Conclusion Total flavonoids of Cydonia oblonga Mill. show the effect of inhibition of myocardial hypertrophy in spontaneously hyperten-sive rats and the mechanism is related to inhibiting ac-tivity of renin-angiotensin-aldosterone system.

ABSTRACT

BACKGROUND:With the development of industrial society and traffic, the incidence of spinal cord injury has gradualy increased. In addition to radiological laboratory examinations, the neurophysiological test also becomes an effective way of auxiliary examination. Due to the high accuracy and easy operating, neurophysiological test is widely used and the evoked potentials play a role in this project. OBJECTIVE:To summarize the application of somatosensory evoked potentials and motor evoked potentials in rabbits of spinal cord injury. METHODS:A computer-based online research of CNKI and PubMed databases was performed with the key words of “spinal cord injury; evoked potentials; animal models” in Chinese and English. Finaly 33 articles were included in the analysis according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION:The operational approach, waveform analysis, application value, influencing factor of somatosensory evoked potentials and motor evoked potentials were determined in details, the correlation between evoked potentials and prognosis assessment in animals was also detected. Somatosensory evoked potentials is a good indicator for the evaluation of dorsal funiculus of spinal cord, it is easy to operate and reflects the changes of sensory functions. Motor evoked potentials can provide sensitive diagnosis of spinal cord diseases, and they wil be used as a means to assess the spinal cord injury during rehabilitation. The combination of the two can provide a more accurate result.

ABSTRACT

BACKGROUND:The majority of studies focus on the lesions of spinal cord injury, while little evidence is available on the change of morphology and structure of distal nerve, muscle and motor endplates fol owing spinal cord injury. OBJECTIVE:To investigate the time window change of the morphology of motor neurons and skeletal muscles caudal to the lesion after spinal cord injury in rats. METHODS:Fifty healthy adult Sprague-Dawley rats were randomly divided into three groups:control group (n=5;without treatment), sham operation group (n=10), and spinal cord injury group (n=35). The sham operated rats only received laminectomy. In the spinal cord injury group, rats were subject to complete T 10 spinal cord injury by total laminectomy and cord transverse resection. Then the morphological change including sciatic nerve, motor endplate and median gastrocnemius was observed for each group at 1, 2, 4, 12, 24 weeks after injury. RESULTS AND CONCLUSION:(1) The myelin sheath layers of sciatic nerve were separated partial y at 4 weeks in rats with spinal cord injury, the myelin sheaths were fragmented with the regeneration of thin-myelinated and unmyelinated axons at 12 weeks. There was a decrease in myelinated axons and an increase in thin-myelinated and unmyelinated axons at 24 weeks. (2) The synaptic gutters of motor endplate, the presynaptic and postsynaptic membrane and synaptic space were distinct at 4 weeks in rats with spinal cord injury, the degenerated motor endplates coexsisted with the intact ones at 12 weeks. The motor endplate disappeared at 24 weeks. (3) There was a slight decrease in muscle cross-sectional area at 2 weeks in rats with spinal cord injury, but no structural change was found, the membrane of myocytes was partial y weakened at 4 weeks, the border of myocytes was obscure with hyperplasia of connective tissue at 12 weeks, and myocytes gathered and in fusion at 24 weeks. As natural history of completely transected spinal cord injury in rats, there were significant changes in morphology of peripheral nerve, motor endplate and skeletal muscles caudal to the lesion at 12 weeks, and the changes were destructive at 24 weeks.
