ABSTRACT
MethodIn the experiment， 46% vol Red Star Erguotou （10 mL·kg·d-1） was used to establish the AONFH rat model， and the intervention effect of JPHGP at different doses （2.5， 5.0， 10.0 g·kg-1） was observed. Jiangusheng pill （JGS， 1.53 g·kg-1） was selected as the positive control. After 8 weeks of administration， the bone histomorphometry of the femoral head was analyzed by Micro-CT imaging， and the area of medullary microvessels in the femoral head was detected by ink perfusion. The pathological change was observed by hematoxylin and eosin （HE） staining. The protein expressions of Platelet endothelial cell adhesion molecule-1 （CD31）， VEGF， VEGFR2， PI3K， phosphor-Akt （p-Akt） and phosphatase and Tensin homologue deleted on chromosome 10 （PTEN） in the femoral head were determined by immunohistochemistry and Western blot. ResultCompared with normal group， the model group presented the fracture and thinning of trabeculae in the femoral head， increased empty bone lacunae， and elevated number and diameter of adipocytes （P<0.01）. Micro-CT imaging revealed a decrease in bone mineral density （BMD）， bone volume fraction （BV/TV）， trabecular thickness （Tb.Th） and trabecular number （Tb.N） （P<0.05， P<0.01） while an increase in bone surface-to-volume ratio （BS/BV） and trabecular separation （Tb.Sp） （P<0.01）. The results of ink perfusion showed that the area of medullary microvessels in the femoral head was reduced （P<0.01）. Compared with model group， JPHGP lowered the empty bone lacunae rate as well as the number and diameter of adipocytes in the femoral head of AONFH rats. Micro-CT imaging indicated that JPHGP low-dose group had elevated BV/TV， Tb.Th and Tb.N （P<0.05， P<0.01） while decreased BS/BV （P<0.01）， and there was an upward trend in BMD while a downward trend in Tb.Sp， but without statistical difference. In addition， JPHGP medium- and high-dose groups had a rise in BMD， BV/TV， Tb.Th and Tb.N （P<0.05， P<0.01）， a decrease in BS/BV and Tb.Sp （P<0.05， P<0.01） and enlarged area of medullary microvessels in the femoral head （P<0.05， P<0.01）. The expressions of CD31， VEGF， VEGFR2， PI3K， p-Akt in the model group were lower than those in the normal group （P<0.01）， and after medium and high doses of JPHGP treatment， the expressions of CD31， PI3K and p-Akt in the femoral head of rats were up-regulated （P<0.01） while the protein expression of PTEN was down-regulated （P<0.01）. Moreover， JPHGP up-regulated the expressions of VEGF and VEGFR2 （P<0.05， P<0.01）. ConclusionJPHGP can repair the vascular injury in AONFH， and its mechanism may be related to the activation of VEGF/VEGFR2/PI3K/Akt signaling pathway. This study provides certain scientific basis and reference for the clinical application of JPHGP. ObjecctiveTo observe the repair effect of Jianpi Huogu prescription （JPHGP） on vascular injury in experimental alcohol-induced osteonecrosis of femoral head （AONFH）， and to explore its mechanism based on vascular endothelial growth factor （VEGF）/VEGFR2/phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway.
ABSTRACT
ObjectiveTo evaluate the effect of Tripterygium wilfordii polyglycoside tablets （TWPT） combined with conventional synthetic disease-modifying antirheumatic drugs （csDMARDs） including methotrexate （MTX） and/or leflunomide （LEF） on autoantibodies in rheumatoid arthritis （RA） patients. MethodPubMed， EMBASE， Web of Science， Cochrane Library， China National Knowledge Infrastructure （CNKI）， VIP， Wanfang Data， and China Biomedical Literature Service System （SinoMed） were searched for randomized controlled trials （RCTs） of TWPT combined with MTX and/or LEF in the treatment of RA patients from database inception to December 1， 2021. Primary outcome indicators included rheumatoid factor （RF） and anti-citrullinated protein antibody （ACPA）， and secondary outcome indicators included immunoglobulin （IgA， IgG， and IgM） and adverse drug events （ADE）. ResultThirty-one RCTs， involving 2 643 adult patients， were included， including 20 RCTs of TWPT combined with MTX， 10 of TWPT combined with LEF， and one of TWPT combined with MTX and TWPT. The follow-up time ranged from two weeks to 13 months. Compared with csDMARDs alone， TWPT combined with other drugs significantly improved serum RF of RA patients ［SMD=-2.45， 95% CI ［-2.97， -1.93］， P<0.000 01］， anti-CCP ［SMD=-1.41， 95% CI （-2.35， -0.48）， P=0.003］， IgM ［SMD=-1.90， 95% CI （-3.03， -0.76）， P=0.001］， and IgA ［SMD=-1.18， 95% CI （-2.23， -0.12）， P=0.03］. There were no significant effects on IgG ［SMD=-1.02， 95% CI （-2.04， 0.01）， P=0.05］ and ADE ［RR=0.87， 95% CI （0.66， 1.15）， P=0.32］. ConclusionThe results of this study show that compared with csDMARDs alone， TWPT combined with csDMARDs can effectively improve the levels of autoantibodies in RA patients without increasing the incidence of ADE. However， due to the limited quality and quantity of the included RCTs， the relevant conclusions are only used as a reference for the clinical diagnosis and treatment of RA， and more high-quality studies are still needed to further confirm their efficacy.
ABSTRACT
Objective@#This study uses structural magnetic resonance imaging to explore changes in the cerebellar lobules in patients with autism spectrum disorder (ASD) and further analyze the correlation between cerebellar structural changes and clinical symptoms of ASD. @*Methods@#A total of 75 patients with ASD and 97 typically developing (TD) subjects from Autism Brain Imaging Data Exchange dataset were recruited. We adopted an advanced automatic cerebellar lobule segmentation technique called CEREbellum Segmentation to segment each cerebellar hemisphere into 12 lobules. Normalized cortical thickness of each lobule was recorded, and group differences in the cortical measures were evaluated. Correlation analysis was also performed between the normalized cortical thickness and the score of Autism Diagnostic Interview-Revised. @*Results@#Results from analysis of variance showed that the normalized cortical thickness of the ASD group differed significantly from that of the TD group; specifically, the ASD group had lower normalized cortical thickness than the TD group. Post-hoc analysis revealed that the differences were more predominant in the left lobule VI, left lobule Crus I and left lobule X, and in the right lobule VI and right lobule Crus I. Lowered normalized cortical thickness in the left lobule Crus I in the ASD patients correlated positively with the abnormality of development evident at or before 36 months subscore. @*Conclusion@#These results suggest abnormal development of cerebellar lobule structures in ASD patients, and such abnormality might significantly influence the pathogenesis of ASD. These findings provide new insights into the neural mechanisms of ASD, which may be clinically relevant to ASD diagnosis.
ABSTRACT
ObjectiveTo observe the anti-swelling and analgesic effects of Jianpi Tongluo prescription （JPTL） and to explore its mechanism initially. MethodA total of 120 ICR mice were divided into normal group， model group， JPTL low-， medium- and high-dose groups （5， 10， 20 g·kg-1） and positive drug （celecoxib， 0.03 g·kg-1） group， with 10 in each group （po，once a day）. Complete freund's adjuvant （CFA） was used to induce the model of chronic inflammatory pain， and xylene-induced ear swelling test， hot plate test and acetic acid writhing test were performed to observe the anti-swelling and analgesic effects of different doses of JPTL in these four acute and chronic models. Further， enzyme-linked immunosorbent assay （ELISA） was used to detect the expressions of prostaglandin E2 （PGE2）， interleukin-1β （IL-1β）， interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α） in serum and inflammatory paw of mice with chronic inflammatory pain， and the expressions of aquaporin 1 （AQP1）， aquaporin 3 （AQP3）， cyclooxygenase 1 （COX1）， cyclooxygenase 2 （COX2） and mitogen-activated protein kinases （MAPKs） in inflammatory paw were detected by Western blot， to explore the preliminary mechanism of JPTL. ResultCompared with the conditions in the normal group， there was a significant increase in the ear swelling of xylene-induced model mice， a shortened paw withdrawal latency in the hot plate test （P<0.01）. Compared with the model group， JPTL remarkably increased the inhibition rate of xylene-induced ear swelling （P<0.05， P<0.01）， prolonged the latency period of writhing caused by acetic acid and reduced the number of writhing （P<0.05， P<0.01）. Compared with normal group, the degree of feet swelling in chronic inflammatory pain mice was significantly increased， the threshold of mechanical pain was decreased and the threshold of cold pain was increased （P<0.05， P<0.01）， the protein contents of AQP1 and AQP3 in inflammatory feet were increased， and the contents of IL-1β， IL-6， TNF-α， PGE2 and COX2 in inflammatory feet were increased in serum and/or inflammatory feet. The protein expression levels of p-p38 MAPK， p-JNK and p-ERK in inflammatory feet were increased （P<0.01）. Compared with the model group， JPTL relieved paw swelling of mice with chronic inflammatory pain， elevated mechanical withdrawal threshold while decreased cold withdrawal threshold， with analgesia lasting for 4 h and the optimal time point for analgesia being 2 h after administration （P<0.05， P<0.01）. Moreover， JPTL down-regulated AQP1， AQP3， COX2， p-p38 MAPK， p-JNK and p-ERK in inflammatory paw of mice with chronic inflammatory pain and reduced IL-1β， IL-6， TNF-α， and PGE2 in serum and/or inflammatory paw， but it had no significant effect on COX1 （P<0.05， P<0.01）. ConclusionJPTL has anti-swelling and analgesic effects， and its mechanism is related to inhibiting the production of cytokines and inflammatory mediators via the down-regulation of MAPKs signaling pathway， which provides an experimental basis for the clinical application of JPTL.
ABSTRACT
ObjectiveFrom the perspective of energy metabolism， the mechanism of Osteoking （OK） in the treatment of myofascial pain syndrome （MPS） was revealed through systems biology prediction combined with holistic animal experimental validation methods. MethodFirstly， the key targets of MPS and their related molecular mechanisms were predicted by the systems biology method， and the core network targets were screened. Then， the network-predicted targets were verified by animal experiments. Specifically， 60 SD rats were randomly divided into normal group， model group， low， medium， and high dose OK groups （0.66， 1.31， 2.63 mL·kg-1）， and positive celecoxib group （21 mg·kg-1）. The MPS model was established by beating combined with a centrifugal exercise method for eight weeks. Except for two days after modeling， the intervention of OK or celecoxib was performed. After the completion of the model， the drug was administered for two weeks. The histopathological changes of trigger point muscle tissue were observed by hematoxylin-eosin staining. The content/activity of Na-K-ATP enzyme （Na+-K+-ATPase）， Ca2+ pump （Ca2+ATPase）， Ca2+， lactate dehydrogenase （LDH）， glutathione （GSH）， malondialal （MDA）， superoxide dismutase （SOD）， cyclic adenosine phosphate （cAMP）， and protein kinase A （PKA） in serum and/or trigger point muscle tissue in MPS rats was detected by enzyme-linked immunosorbent assay. Protein expression levels of PKA and the peroxisome proliferator-activated receptor γ coactivator 1α （PGC1α） in MPS rats were detected by immunohistochemistry. The protein expression levels of PKA， PGC1α， and mitochondrial transcription factor A （TFAM） in MPS rats were detected by Western blot. ResultThe network prediction results suggest that OK acts on the key target of energy metabolism related to the occurrence and development of MPS and may participate in the activation of the cAMP/PKA/PGC1α signaling pathway. The experimental validation results show that compared with the normal group， contracture nodules and disordered arrangement of muscle fibers appear in the trigger point muscle tissue of MPS rats. Na+-K+-ATPase， Ca2+ATPase， SOD activity， Ca2+， and GSH contents in serum and/or trigger point muscle tissue are significantly decreased （P<0.01）. Both LDH activity and MDA contents are significantly increased （P<0.01）， and the protein expression levels of cAMP， PKA， PGC1α， and TFAM are significantly decreased （P<0.01）. Compared with the model group， OK improves the histopathological morphology of trigger point muscle fibers in MPS rats， and after the intervention of OK， Na+-K+-ATPase， Ca2+ATPase， SOD activity， Ca2+， and GSH contents in serum and/or trigger point muscle tissue in MPS rats are significantly increased （P<0.05， P<0.01）. LDH activity and MDA contents are significantly reduced （P<0.05， P<0.01）. The protein expression levels of cAMP， PKA， PGC1α， and TFAM are significantly increased （P<0.05， P<0.01）. ConclusionThe mechanism of OK's intervention in MPS rats may be related to its effective activation of the cAMP/PKA/PGC1α signaling pathway， thus promoting mitochondrial energy metabolism and trigger point muscle fiber damage repair in muscle cells.
ABSTRACT
ObjectiveTo clarify the intervention effect of Osteoking （OK） in rats with myofascial pain syndrome （MPS） and preliminarily explore the pharmacological mechanism of OK in relieving chronic pain from the perspective of anti-inflammatory disease. MethodThe 60 SD rats were divided into normal group， model group， low， medium， and high dose OK groups （0.66， 1.31， 2.63 mL·kg-1）， and positive celecoxib group （21 mg·kg-1）. The MPS rat model was established by beating combined with the centrifugal exercise method， and the OK and celecoxib were given at the same time. SMALGO paw pressure pain manometer detected the shock pain point tenderness threshold of rats， and the Von-Frey needle and acetone stimulation method detected the mechanical hyperalgesia threshold and cold hyperalgesia stimulation response respectively. Eight weeks and 10 weeks after modeling， the spontaneous discharge state and convulsion response of MPS rats were determined by electromyograph （EMG） instrument. The gait changes of MPS rats were detected using a CatWalk gait analyzer. The expression levels of interleukin-1 β （IL-1β）， tumor necrosis factor-α （TNF-α）， substance P （SP）， and bradykinin （BK） were measured by enzyme-linked immunosorbent assay （ELISA）. The protein expression levels of nuclear transcription factor-κB （NF-κB） inhibiting protein α （IκBα）， phosphorylates （p）- IκBα， NF-κB p65， and p-NF-κB p65 were detected in MPS rats by Western blot. The positive expression of p-NF-κB p65 was detected by immunofluorescence. ResultCompared with the normal group， the model group shows 100% positive rates for EMG signal and local convulsions response at both the 8th and 10th weeks. The tenderness threshold and mechanical hyperalgesia threshold are significantly reduced. Cold hyperalgesia score is significantly increased， and gait is abnormal. The expression levels of serum and trigger points IL-1β， TNF-α， SP， BK， p-IκBα， and p-NF-κB p65， as well as the positive expression intensity of p-NF-κB p65 are significantly increased （P<0.01）. Compared with the model group， the positive rate of EMG detection and local convulsion response is significantly reduced in the medium and high dose OK groups （P<0.05）. The tenderness threshold and mechanical hyperalgesia threshold increase significantly in the medium and high dose OK groups， and the cold hyperalgesia score is significantly reduced in the high dose OK group （P<0.01）. The standing time， swing time， and walking period are significantly increased. The swing speed， maximum contact area， and maximum contact intensity are significantly decreased in the high dose OK group （P<0.05）. Moreover， the protein expression levels of p-IκBα/IκBα and p-NF-κB p65/NF-κB p65 are significantly reduced in the medium and high dose OK groups （P<0.05，P<0.01）. The positive expression intensity of p-NF-κB p65 is significantly decreased in the high dose OK group （P<0.01）. ConclusionThe mechanism of OK in relieving the pain in trigger points of MPS and improving gait abnormalities is related to the downregulation of the NF-κB p65 inflammatory signaling pathway to reduce the expression of inflammatory factors and pain mediators in blood and trigger point tissue.
ABSTRACT
ObjectiveTo investigate the protective effect of Jianpi Huogu prescription （JPHGP） on the functional injury of vascular endothelial cells caused by alcohol and explore its mechanism based on protein kinase B/c-Jun amino-terminal kinase/p38 MAPK （Akt/JNK/p38 MAPK） signaling pathway. MethodThrough chick embryo allantoic membrane， thoracic aortic ring， and migration， invasion， adhesion， and lumen formation of human umbilical vein endothelial cells （HUVEC）， the effect of JPHGP with different concentrations （8， 16 and 32 μg·L-1） on angiogenesis was observed in the presence or absence of alcohol. The expression levels of phosphorylation of Akt， JNK， and p38 MAPK were determined by Western blot. ResultAs compared with the normal group， the number and length of capillaries around the arterial ring in the model group were decreased， and the migration， invasion， and lumen formation capacity of HUVEC were decreased （P<0.05， P<0.01）. After treatment with 16 and 32 μg·L-1 JPHGP， the length of neovascularization in chick embryo allantoic membrane was significantly increased （P<0.05， P<0.01）. Compared with the model group， the 8， 16， and 32 μg·L-1 JPHGP groups increased the number of capillaries around the thoracic aortic ring in a concentration-dependent manner （P<0.05， P<0.01）， and the 32 μg·L-1 JPHGP group increased the length of capillaries around the thoracic aortic ring （P<0.05）. The 16 and 32 μg·L-1 JPHGP groups enhanced the migration， invasion， and lumen formation capacity of HUVEC. The results of Western blot showed that， as compared with the normal group， the protein expression levels of p-JNK/JNK， p-p38 MAPK/p38 MAPK， and p-Akt/Akt were significantly decreased in the model group （P<0.01）， and as compared with the model group， the protein expression levels of p-p38 MAPK/p38 MAPK and p-Akt/Akt were significantly increased in the 8， 16， and 32 μg·L-1 JPHGP groups （P<0.01） and the protein expression level of p-JNK/JNK was increased significantly in the 16 and 32 μg·L-1 JPHGP groups （P<0.01）. ConclusionJPHGP has a protective effect on the functional injury of vascular endothelial cells caused by alcohol， and its mechanism may be related to the activation of Akt/JNK/p38 MAPK signaling pathway. Relevant research results will provide certain scientific basis for clarifying the effect of JPHGP on 'invigorating spleen and promoting blood circulation'.
ABSTRACT
Objective:To investigate the safety and curative effect of transumbilical single-incision laparoscopy with fascial platform for ovarian cystectomy.Methods:The clinical data of 105 patients underwent laparoscopy ovarian cystectomy in Fujian Maternity and Child Health Hospital from June 2018 to December 2021 were retrospectively analyzed. Among them, 45 patients underwent transumbilical single-incision laparoscopy with fascial platform for ovarian cystectomy (observation group), and 60 patients underwent multi-port laparoscopy for ovarian cystectomy (control group). The operative time, intraoperative bleeding, conversion to open surgery, cyst rupture, surgical collateral injury, postoperative exhaust time, postoperative hospital stays, hospitalization cost and postoperative infection, etc were recorded. The face rating scale (FRS) was used to evaluate the pain at 6 and 24 h after operation; the incision satisfaction was evaluated by the Kiyak satisfaction scale at 2 months after operation.Results:The operation was carried out successfully in both groups without surgical collateral injury or conversion to open surgery. There were no significant differences in operative time, intraoperative bleeding, postoperative hospital stays, hospitalization cost, cyst rupture rate and postoperative infection rate between 2 groups ( P>0.05); the postoperative exhaust time and FRS 6 and 24 h after operation in observation group were significantly less than those in control group: (22.1 ± 3.5) h vs. (23.9 ± 3.8) h, 1 (0, 2) scores vs. 2 (1, 4) scores and 1 (0, 1) scores vs. 1 (0, 2) scores, the incision satisfaction score was significantly higher than that in control group: 5 (4, 5) scores vs. 4 (3, 4) scores, and there were statistical differences ( P<0.05 or <0.01). Conclusions:Transumbilical single-incision laparoscopy with fascial platform for ovarian cystectomy is safe and feasible, with concealed incision and high patient satisfaction, and has good clinical application value.
ABSTRACT
Objective:To analyze the effect of anticoagulant or antiplatelet drugs on bleeding and cardio-cerebral vascular events in perioperative period of catherization for peritoneal dialysis.Methods:The clinical data of patients undergoing peritoneal dialysis catheterization in Peking University Third Hospital from July 1, 2010 to December 31, 2020 were collected and analyzed retrospectively. The patients were divided into drugs discontinuation group and drugs continuation group according to whether the anticoagulant drugs or antiplatelet drugs were discontinued or not. Baseline clinical data and bleeding and cardio-cerebral events after surgery were compared between the two groups. Multivariate logistic regression model was used to analyze the influencing factors for bleeding and cardio-cerebral events.Results:A total of 57 patients were included in the study, with 34 males and 23 females. The age was (67.37±13.93) years old (range from 27 to 97 years old). There were 37 patients in drugs discontinuation group and 20 patients in drugs continuation group. The proportions of acute myocardial infarction events in drugs continuation group were higher than those in drugs discontinuation group in 3 months and 6 months before surgery (10/20 vs 3/37, χ2=10.671, P=0.001; 11/20 vs 3/37, χ2=12.980, P<0.001 respectively). The median drugs discontinuation time was 5.0(2.0, 14.0) d (range from 1 to 30 d) before surgery, and median restore medication time was 4.0(3.0, 7.0) d (range from 1 to 14 d) after surgery in drugs discontinuation group. There was no significant difference in the proportion of bleeding (10/37 vs 8/20, χ2=1.011, P=0.315) and cardio-cerebral events (4/37 vs 0/20, χ2=0.964, P=0.326) between drugs discontinuation group and drugs continuation group within 2 weeks after surgery. The results of multivariate logistic regression analysis showed that drugs discontinuation before surgery was not an independent influencing factor for bleeding events ( OR=0.656, 95% CI 0.195-2.206, P=0.496), however combination of aspirin and clopidogrel before surgery was an independent influencing factor for bleeding events ( OR=4.038, 95% CI 1.044-15.626, P=0.043). All cardio-cerebral events (4 cases) happened in drugs discontinuation group, and myocardial angina in 6 months before surgery ( OR=9.764, 95% CI 0.928-102.682, P=0.058) and increased serum calcium concentration ( OR=1.491, 95% CI 0.976-2.278, P=0.065) were related with an elevated trend for cardio-cerebral events. Conclusions:Whether anticoagulant or antiplatelet drugs are discontinued before catherization surgery for peritoneal dialysis is not an independent influencing factor for bleeding events after surgery. The risk of postoperative bleeding in patients using combination of aspirin and clopidogrel should be paid attention. Myocardial angina in 6 months before surgery and higher serum calcium are related with an elevated trend for cardio-cerebral events after drugs discontinuation.
ABSTRACT
ObjectiveTo observe the intervention effect of Ruyi Zhenbao pills （RYZBP） on central pain after thalamic stroke in mice and explore the underlying mechanism. MethodThe central post-stroke pain syndrome （CPSP） model was induced by stereotactic injection of type Ⅳ collagenase into the hypothalamus in mice. The mice were divided into a sham group， a model group， low-， medium-， and high-dose RYZBP groups （0.65， 1.3， 2.6 g·kg-1）， and a pregabalin group （0.075 g·kg-1）. Seven days after modeling， the mice in the groups with drug intervention were administered with corresponding drugs by gavage according to the body mass， once per day for 25 days， while those in the sham group and the model group received an equal volume of normal saline. During this period， mechanical pain and cold pain were detected at different time points， and the apoptotic state of brain tissue cells was detected by in situ terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling （TUNEL）. The 36 classical broad-spectrum inflammatory factors were quantitatively analyzed by liquid-phase chip technology， and differential molecules were screened out and verified by Western blot and enzyme-linked immunosorbent assay （ELISA）. ResultCompared with sham operation group, mechanical pain threshold and cold sensitive pain threshold in model group were significantly changed （P<0.01）. TUNEL results showed that apoptosis of brain cells was obvious. Western blot and ELISA results showed that the expressions of interleukin-1α (IL-1α) and chemokine ligand 5 (CCL5) increased in hypothalamus tissue and serum， while the expressions of Ang-2, granulocyte-colony-stimulating factor (G-CSF) and IL-4 decreased significantly （P<0.01）. Compared with model group， RYZBW dose groups significantly increased mechanical pain threshold， decreased cold sensitivity pain threshold， decreased hypothalamus cell apoptosis ratio （P<0.01）， decreased the expression of IL-1α and CCL5 in hypothalamus tissue and serum， while the expression of ANG-2， G-CSF and IL-4 were significantly increased （P<0.05）. ConclusionRYZBP can relieve hyperalgesia in CPSP mice， and its mechanism is related to the regulation of the expression of pro-/anti-inflammatory factors IL-1α， CCL5， IL-4， G-CSF， and Ang-2.
ABSTRACT
Stress urinary incontinence (SUI) is closely related to pregnancy and delivery. With the implementation of the three-child policy and the increasing number of pregnant women at advanced age or with obesity, the prevalence of SUI during pregnancy and the postpartum period is increasing gradually. Risk factors of SUI that are associated with pregnancy and childbirth include delivery mode, advanced maternal age, overweight/obesity, macrosomia, prolonged second stage of labor, epidural anesthesia, and breastfeeding. Identification of such risk factors is crucial for early intervention for high-risk patients, which would be conducive to reducing the risk of long-term SUI.
ABSTRACT
Objective:To ascertain the endemic status of paragonimiasis in Zhejiang Province.Methods:From 2005 to 2020, 2-3 villages in 1-2 counties (cities, districts, hereinafter refferred to as counties) in historical endemic areas of paragonimiasis in Zhejiang Province were selected for monitoring each year. In each village, 50 to 150 local residents were selected as monitoring subjects, venous blood samples were collected, and serum Paragonimus antibody was detected by enzyme-linked immunosorbent assay (ELISA). Fifty to 100 intermediate hosts crabs or crayfish were collected in each village, and the infection of Paragonimus metacercaria was detected by crushing precipitation. Results:The positive rate of Paragonimus antibody was 2.9% (94/3 297); 3 929 crabs or crayfish were divided into 2 749 groups, 790 of which were found to have Paragonimus metacercaria infection, with a Paragonimus metacercaria infection rate of 28.7%. Conclusions:Paragonimus transmission chain exists in some counties of Zhejiang Province, which still has the potential risk of Paragonimus epidemic. Therefore, it is necessary to strengthen monitoring and carry out extensive health education to improve residents' self-protection awareness.
ABSTRACT
Objective:To investigate the current situation of core competence of anesthesiology nurses in China, and to provide basis for formulating and perfecting the training curriculum of anesthesiology nurses.Methods:The cluster sampling method was used, and 231 nurses in the department of anesthesiology were investigated by using the general data questionnaire and the self-assessment form of core competence of specialized nurses in the department of anesthesiology.Results:Anesthesiology nurses scored (3.7±0.5) points in their core competencies, of which 43.2% and 36.4% had complete mastery of humanistic literacy, and communication and coordination skills, respectively, and only 4.3% of them had mastered scientific research ability.The core competence scores of anesthesiology nurses with the title of head nurse or above positions and deputy chief nurse or above titles were significantly higher than those of other positions and titles ( P<0.05). Conclusions:The self-evaluation of core competence of specialized nurses in anesthesiology department is at a medium level.There are differences in core competencies among nurses in the department of anesthesiology with different positions and titles.It is suggested that the training of specialized nurses should be guided by core competence.
ABSTRACT
Objective:To investigate and analyze the awareness of malignant hyperthermia (MH) in anesthesiology nurses in mainland China.Methods:From November 2021 to January 2022, anesthesiology nurses of secondary hospitals or above in Chinese mainland were enrolled by convenience sampling and investigated by a self-designed questionnaire on the awareness of MH.The system automatically recorded the situation of questionnaires.Results:A total of 2 058 anesthesiology nurses participated in the survey, distributed in 21 provinces, 2 autonomous regions (Ningxia Hui Autonomous Region, Guangxi Zhuang Autonomous Region) and 4 municipalities directly under the central government, and 2 049 questionnaires were effectively received with effective recovery of 99.56%.The correct answers to questions related to the treatment of MH, characteristics of the disease, classification, susceptible population, screening method of the susceptible population, genetic mode, inducing factors, the first symptoms and the best infusion time of dantrolene, preparation method of domestic dantrolene and the first dose were 86.58%, 82.33%, 58.18%, 50.90%, 50.76%, 50.42%, 45.73%, 32.89%, 51.25%, 48.32% and 46.51%, respectively.Only 27.13% of anesthesiology nurses expressed that dantrolene was available in their hospital.The scores of knowledge about MH among anesthesiology nurses in hospitals of province-level municipalities and provincial capital cities were significantly higher than those in other cities ( P<0.001). The scores of knowledge about MH among the anesthesiology nurses in secondary hospitals were significantly higher than those in tertiary hospitals ( P<0.05). There was no significant difference in the scores of knowledge about MH among anesthesiology nurses with different professional titles, educational backgrounds, and working years ( P>0.05). Conclusions:Anesthesiology nurses in mainland China have insufficient awareness of MH.Popularizing the knowledge about MH and strengthening the awareness of MH in medical staff in the department of anesthesiology throughout the country may be of great significance in improving the diagnosis and treatment of MH in China.
ABSTRACT
Objective:To explore the effect of Baduanjin combined with limb function exercise on trunk control and living ability of stroke patients with hemiplegia.Methods:From September 2019 to March 2021, a total of 86 stroke patients with hemiplegia admitted into the First Affiliated Hospital of Zhengzhou University who met the inclusion criteria were selected and divided into the control group and the experimental group with 43 cases in each group according to the random number table method. The control group was given limb function exercise, while the experimental group was given Baduanjin combined with limb function exercise, and the intervention time was 6 weeks. The Trunk impairment scale (TIS), Berg balance scale (BBS), Fugl-Meyer assessment of motor function (FMA), Barthel index (BI) scores and the thicknesses of transverse abdominis and multifidus muscle were compared between the two groups before and after the intervention.Results:After the intervention, the TIS, BBS, FMA and BI scores of the experimental group were significantly higher than that of the control group [(19.52±2.68) vs (16.78±2.51) points, (43.19±5.03) vs (35.62±4.89) points, (71.24±7.39) vs (59.26±6.35) points, (69.52±6.81) vs (62.31±6.46) points], the thickness of transversus abdominis and multifidus were significantly greater than that in the control group [(2.76±0.39) vs (2.39±0.35) mm, (24.37±1.69) vs (23.67±1.45) mm] (all P<0.05). Conclusion:Baduanjin combined with limb function exercise can improve the trunk control ability, balance function, motor function and daily life ability of stroke patients with hemiplegia.
ABSTRACT
Background/Aims@#To investigate postpartum hepatic flares and associated factors in highly viremic pregnant patients in the immune tolerance phase who adopted telbivudine (LdT) treatment in the last trimester to reduce vertical transmission of hepatitis B virus. @*Methods@#Hepatitis B e antigen (HBeAg)-positive, highly viremic pregnant women were recruited for this prospective study. Treatment with LdT was started from 28 weeks of gestation. Virological and biochemical markers were examined before LdT treatment, antepartum and postpartum. Serial blood samples at the same time were collected to detect cytokines and cortisol (COR). @*Results@#Fifty-six of 153 patients (36.6%) had postpartum hepatic flares, defined as a 2-fold increase in alanine aminotransferase 6 weeks after delivery. Age and the antepartum alanine aminotransferase and postpartum HBeAg levels were independent influencing factors of postpartum hepatic flares. Cytokines showed no regularity during or after pregnancy. Compared with the patients with no postpartum flares, the patients with flares had lower baseline interferon γ and COR levels (p=0.022 and p=0.028) and higher postpartum interferon γ levels (p=0.026). @*Conclusions@#A high proportion of highly viremic and immune-tolerant pregnant patients treated with LdT in the last trimester had postpartum hepatic flares, which implied that these patients entered the immune clearance phase after delivery. Thus, this may create an appropriate opportunity for re-antiviral therapy.
ABSTRACT
Traditional Chinese Medicine (TCM) has become an important part of the health system in the Sultanate of Oman. Although there is no independent law, the local health department has implemented the administrative measures such as the admittance assessment system of TCM doctors and the standardized examination and approval of TCM clinics. The development of TCM in the Sultanate of Oman is supported by the policies of the two governments, with the characteristics likemedical cooperation starting with high-level personnel, the cooperation in economy, trade and medical treatment, TCM and local traditional medicine showing inclusive with good base, and the advantages of TCM theory and treatment meeting the needs of the local medical market. The prospect of cooperation in TCM market is broad. It is suggested that the local government should promote the legislation of traditional medicine and improve the admittance system of practitioners. China needs to promote the formulation of international standards of TCM and optimize the cooperation platform of TCM by using Internet and other technologies. The practitioners in China need to carry out medical activities on the premise of understanding and respecting the local cultural background.In order to promote the development of TCM in Arab countries, the Sultanate of Oman will radiate the whole Middle East through the above strategies.
ABSTRACT
Overweight or obese women have a significantly increased risk of gestational diabetes mellitus (GDM). With the increasing prevalence of obesity among women of reproductive age, the prevalence of GDM has also risen. The prevention of GDM during pregnancy is particularly important in reducing the adverse pregnancy outcomes for both mothers and their offspring and decreasing the economic burden of the society. Lifestyle interventions (exercises, dietary), dietary supplementation, and pharmacological approaches are the main preventive measures. Exercise intervention and myo-inositol supplementation are effective in preventing GDM; dietary intervention and combined lifestyle intervention have some benefits, but the results remain controversial; probiotic supplementation and prophylactic use of metformin seem to be ineffective; the effectiveness of vitamin D supplementation is unclear.
ABSTRACT
Objective:To explore the risk factors influencing the short-term mortality of patients with sepsis in intensive care unit (ICU) and the combined value of predicting prognosis.Methods:A retrospective analysis was performed on 104 patients with sepsis admitted to emergency ICU of Jiangsu Provincial Hospital of Traditional Chinese Medicine from January 2018 to August 2019. Multiple general information containing gender, age, past history as well as complications and sequential organ failure assessment (SOFA) score, mean arterial pressure (MAP), blood routine examination, hepatic and renal function, coagulation indicators and procalcitonin (PCT) were collected within 24 hours of admission. Patients were divided into death group and survival group according to the 28-day outcome. Univariate and multivariate Logistic regression analysis were used to find the effective factors influencing the prognosis of sepsis. Receiver operating characteristic (ROC) curve was drawn to evaluate the value of related indexes in predicting the prognosis of sepsis. Correlation between parameters that might be relevant to disease severity and SOFA score was evaluated by Pearson or Spearman correlation analysis.Results:104 patients were enrolled for final analysis, of whom 60 patients survived, while the others died with a 28-day mortality of 42.3%. ① Univariate analysis results: the incidence of acute kidney injury (AKI), SOFA score, serum creatinine (SCr), D-dimer, activated partial thromboplastin time (APTT), international normalized ratio (INR) and PCT in the death group were significantly higher than those in the survival group [incidence of AKI: 70.5% (31/44) vs. 36.7% (22/60), SOFA score: 11.0 (8.0, 13.0) vs. 8.0 (6.2, 10.0), SCr (μmol/L): 108.8 (65.5, 235.6) vs. 75.1 (55.1, 109.5), D-dimer (mg/L): 4.1 (1.6, 11.6) vs. 2.1 (1.2, 4.3), APTT (s): 42.6 (37.7, 55.7) vs. 40.3 (35.9, 44.7), INR: 1.3 (1.2, 1.5) vs. 1.2 (1.1, 1.4), PCT (μg/L): 3.1 (0.4, 39.9) vs. 0.3 (0.1, 3.4), all P < 0.05]. ② Multivariate Logistic regression analysis results: all indicators of univariate analysis were included in the multivariate Logistic regression model considering interaction between each variable. Multivariate Logistic regression analysis was repeated based on conditional backward method. Age, SOFA score, MAP, neutrophil (NEU), lymphocyte (LYM) and APTT were automatically selected by SPSS software to build the predicting model. Analysis results showed that SOFA score, NEU and LYM were independent risk factors for the short-term prognosis of sepsis [SOFA score: odds ratio ( OR) = 1.22, 95% confidence interval (95% CI) was 1.04-1.44, P = 0.02; NEU: OR = 1.14, 95% CI was 1.03-1.26, P = 0.01; LYM: OR = 0.79, 95% CI was 0.66-0.95, P = 0.01]. ③ ROC curve analysis results: the above six-variable prediction model had the optimal fitting degree defaulted by SPSS. ROC curve showed that the combination of age [area under ROC curve (AUC) = 0.60], SOFA score (AUC = 0.71), MAP (AUC = 0.53), NEU (AUC = 0.59), LYM (AUC = 0.54) and APTT (AUC = 0.61) had better sensitivity (79.5%) and specificity (65.0%) as well as the maximal AUC (AUC = 0.75), which suggested that combined prediction had higher diagnostic value in predicting the short-term prognosis of sepsis.④ Correlation analysis showed that NEU, D-dimer, prothrombin time (PT), APTT, INR and PCT were positively correlated with SOFA score ( r values were 0.26, 0.28, 0.21, 0.22, 0.10, 0.38, respectively, all P < 0.05). Conclusions:SOFA score, NEU and LYM were independent risk factors for the short-term prognosis of sepsis. The combination of age, SOFA score, MAP, NEU, LYM and APTT were more accurate than any single factor in predicting the short-term prognosis of sepsis and had higher diagnostic value. NEU, D-dimer, PT, APTT, INR and PCT were correlated with SOFA score.
ABSTRACT
Objective@#To explore the correlation between the level of anti-mitochondrial antibody (AMA) and clinical indicators of first visited primary biliary cholangitis (PBC) patients with positive AMA.@*Methods@#From January 2013 to December 2016, the clinical data of 1 323 patients with positive AMA and/or AMA-M2 detected for the first time were collected through the Information System of Peking University People′s Hospital. Among them, 183 were detected by indirect immunofluorescence assay, 431 were measured by immunoblotting, and 709 were determined by enzyme-linked immunosorbent assay (ELISA). Patients were divided into undiagnosed PBC group (non-PBC group, 973 cases) and newly diagnosed PBC group (new-PBC group, 350 cases including 268 cases of non-liver cirrhosis and 82 cases of liver cirrhosis); among 709 cases detected by ELISA, there were 567 cases in the non-PBC group and 142 cases in the new-PBC group (115 cases of non-liver cirrhosis PBC group and 27 cases of liver cirrhosis PBC group). Among 183 cases determined by indirect immunofluorescence assay, there were 118 cases in the non-PBC group and 65 cases in the new-PBC group. Among them 69 cases with low AMA titer (1∶40—1∶80) (53 cases of non-PBC group and 16 cases of new-PBC group), 95 cases with medium titer (1∶160—1∶320) (59 cases of non-PBC group and 36 cases of new-PBC group) and 19 cases with high titer (≥1∶640) (six cases of non-PBC group and 13 cases of new-PBC group). AMA levels among groups were compared, and its correlation with clinical serology and cirrhosis indicators of PBC including immunoglobulin (Ig)G, IgM, platelet, alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltranspeptadase (GGT), alkaline phosphatase (ALP), serum total protein, serum albumin, total bilirubin (TBil), total cholesterol (TC), and aspartate aminotransferase to platelet ratio index (APRI) and fibrosis (Fib-4) was analysed. Mann-Whitney U test, Kruskal-Wallis test, and linear regression analysis were performed for statistical analysis.@*Results@#By ELISA method, the median titer of AMA-M2 of 709 patients was 53 RU/mL, the serum AMA and AMA-M2 levels of new-PBC group were both higher than those of non-PBC group (1∶320 vs. 1∶80, 180 RU/mL vs. 47 RU/mL), and the differences were statistically significant (χ2 = 14.111, Z = -7.531, both P < 0.01). In non-PBC group, the AMA-M2 value was positively correlated with age, serum IgG, IgM, AST, GGT, ALP, serum total protein and TC, all of which were statistically significant (Rho = 0.114, 0.108, 0.337, 0.089, 0.197, 0.086, 0.121 and 0.073, all P<0.05). In new-PBC group, AMA-M2 value was positively correlated with age, IgM, serum total protein and TC, however was negatively correlated with platelet count, all of which were statistically significant (Rho = 0.218, 0.483, 0.230, 0.161, and -0.183, all P<0.05). The median values of serum AMA and AMA-M2 of PBC without liver cirrhosis group were both tended to be lower than those of PBC with liver cirrhosis (1∶160 vs. 1∶320; 174 RU/mL vs. 495 RU/mL), however the differences were not statistically significant (both P>0.05). AMA-M2 value of patients in PBC with liver cirrhosis group was positively correlated with IgM level (r = 0.38, P = 0.039), but was not correlated with APRI and Fib-4 (all P > 0.05). The median of AMA value of 183 patients who underwent indirect immunofluorescence test was 1∶160. In non-PBC group, the IgM levels of patients with low, medium and high AMA titers gradually increased (the median levels were 1.2, 1.7 and 1.8 g/L, respectively); in new-PBC group, the levels of IgM, GGT and ALP of patients with low, medium and high AMA titers gradually increased (median IgM levels were 1.5, 3.7 and 4.1 g/L, respectively; GGT levels were 144, 182 and 317 U/L, respectively; and ALP levels were 137, 168 and 221 U/L, respectively), and the differences were statistically significant (χ2 =6.260, 7.081, 8.030, 15.226, all P<0.05). In non-PBC group, the median level of serum AMA-M2 of men was lower than that of women (41 RU/L vs. 50 RU/L), and the difference was statistically significant (Z = -2.945, P = 0.003). In new-PBC group, the median level of serum AMA-M2 of men tended to be lower than that of women (113 RU/mL vs. 206 RU/mL), but the difference was not statistically significant (P=0.257).@*Conclusion@#Serum AMA level is correlated with many clinical parameters and may be related with the disease severity in patients with PBC.
