RESUMO

OBJECTIVE: To observe the clinical effect of bird-induced anus-lifting surgery (BIAL) combined with oral Relinqing Granules (RG) in the treatment of lower urinary tract symptoms / chronic prostatitis (LUTS/CP) with damp-heat syndrome using infrared thermal imaging (ITI). METHODS: This study included 165 cases of LUTS/CP with damp-heat syndrome treated in the Departments of Andrology and Urology of our hospital, which were divided into three groups of an equal number and treated by medication of oral tamsulosin hydrochloride at 0.2 mg, qd plus levofloxacin at 0.2 g bid (control), anus-lifting exercise (15 lifts once a day) combined with oral RG at 8 g tid (routine treatment) and BIAL (15 lifts once a day) combined with oral RG at 8 g tid (BIAL+RG), respectively, all for two weeks. We recorded the ITI indicators, NIH-CPSI and Self-Rating Anxiety Scale (SAS) scores of patients before and after treatment, observed adverse reactions during the treatment, and compared them among the three groups of patients. RESULTS: Compared with the baseline, NIH-CPSI and SAS scores were significantly reduced in all the three groups after treatment (P < 0.05), even more significantly in the BIAL+RG (10.49 ± 2.97 and 49.73 ± 2.79) than in the control (21.15 ± 3.56 and 52.62 ± 5.38) and routine treatment groups (15.55 ± 2.77 and 52.35 ± 3.87) (P < 0.05). The ITI temperature at the related parts of the body was remarkably decreased in the three groups after treatment (P < 0.05), even lower in the BIAL+RG group (30.47 ± 1.61, 32.14 ± 1.25, 31.16 ± 1.58, 31.97 ± 1.19) than in the control (33.39 ± 0.6, 33.64 ± 1.07, 32.78 ± 0.58, 33.18 ± 0.78) and routine treatment groups (31.93 ± 1.14, 33.06 ± 0.8, 33.08 ± 0.82, 33.17 ± 1.05) (P < 0.05), with statistically significant difference from the baseline in the BIAL+RG group after 12 hours and 24 hours of treatment (ï¼»34.26 ± 0.06ï¼½ vs ï¼»32.65 ± 0.05ï¼½ and ï¼»32.72 ± 0.09ï¼½, P < 0.05), but not between the two time points (P > 0.05). The incidence rate of adverse reactions was markedly lower in the BIAL+RG and routine treatment groups than in the control (P < 0.05) but not significantly different between the BIAL+RG and routine treatment groups (P > 0.05). CONCLUSION: Bird-induced anus-lifting surgery combined with oral Relinqing Granules can safely and significantly improve infrared thermal imaging indicators and NIH-CPSI scores in LUTS/CP patients with damp-heat syndrome.

RESUMO

INTRODUCTION: Quitting smoking, the critical path to reach the global targets of reducing tobacco use, can bring major and immediate health benefits to smokers. Exploring factors that help individuals to quit smoking is of great importance. The present study explored influencing factors on smoking cessation, in order to provide comprehensive reference for tobacco control policies. METHODS: Ex-smokers and current smokers were recruited online in this cross-sectional survey, from 1 October to 31 November 2022, in China. The observational data were collected using a questionnaire to collect information with respect to sociodemographic characteristics of smokers, attitudes towards smoking cessation, details of smoking cessation, and different potential factors related to smoking cessation through open-ended questions. RESULTS: A total of 638 smokers from 30 provinces were recruited as eligible respondents, with a mean age of 37.3 ± 11.7 years and a mean smoking history of 15.9 ± 13.7 years. The percentage of males was 92.3%. Of the 638 respondents, only 3.9% had no intention to stop smoking. Among 155 subjects who had quitted smoking successfully, willpower (55.5%) was considered as the most important contributing factor. Among 365 subjects who tried to quit but failed, lack of willpower (28.2%), tobacco dependence (16.2%), influence of surrounding smokers or smoking environments (15.9%), bad moods (9.9%), stress from work or life (7.9%), habits (7.1%), socialization (4.1%), and easy availability of tobacco (2.7%) were considered as the adverse factors leading to failure in quitting smoking. CONCLUSIONS: Willpower and support from family members were the vital factors that lead to successful smoking cessation. Future tobacco control policies should also focus on addressing withdrawal symptoms and creating smoke-free environments as well as other factors.

RESUMO

In this work, twenty-five water-soluble constituents were isolated from the bulbs of Lilium davidii var. unicolor, including two new compounds termed liliumtides A and B (1-2), and seventeen known compounds (3-4, 6-13, 15, 17, 21-25) isolated from the genus of Lilium for the first time. Their structures were established using high-resolution electrospray ionization mass spectroscopy and 1D and 2D nuclear magnetic resonance data. To confirm furtherly the absolute configuration of liliumtide A, and to accumulate enough sample to study the anti-insomnia effect, a total synthesis for liliumtide A was achieved by four steps. The pentobarbital-induced sleeping time test showed that compared with the blank control group, the liliumtide A decreased sleep latency and significantly increased the sleep time. These results suggested that liliumtide A could be investigated as a natural anti-insomnia lead compound in the pharmaceutical and food industries.

RESUMO

Aeschynomene indica has a distinctive symbiosis with Bradyrhizobium in which nodulation is Nod factor-independent. In this study, we characterised three Gram-negative and rod-shaped strains (83002T, 81013 and 83012) isolated from root nodules of Aeschynomene indica in Shandong Peninsula. The major cellular fatty acids of isolates were C16:0, C18:0, C18:1 ω7c 11-methyl, summed feature 3 and summed feature 8. The major polar lipids were phosphatidylethanolamine (PE), aminolipids (AL) and phosphatidylcholine (PC). Phylogenetic analysis based on the 16S rRNA locus showed that they belonged to the Bradyrhizobium genus, and shared the highest similarity to the type strains Bradyrhizobium oligotrophicum S58T and Bradyrhizobium denitrificans LMG 8443T. As expected, analysis of concatenated sequences of six housekeeping genes (atpD, recA, glnII, dnaK, gyrB, and rpoB) and nifH gene proposed that these three strains formed a distinct clade within the genus Bradyrhizobium. The highest average nucleotide identity and DNA-DNA hybridization values of the three strains in comparison to the closest Bradyrhizobium species were 87.5% and 65.3%, respectively, which are far below the threshold of species delineation, and thus confirmed the three strains as a new species. The genome size of strain 83002T is 7.52 Mbp, and the DNA G+C content is 65.42 mol%. Strain 83002T (=KCTC 82266T=MCCC 1K04775T) was chosen as the type strain of the new species, for which the name Bradyrhizobium aeschynomenes sp. nov. was proposed.

RESUMO

BACKGROUND: Charcot neuroarthropathy (CN) is a systemic disease characterized by progressive bone loss and destruction, which is usually closely related to diabetes, HIV, etc. However, CN caused by syringomyelia accounts for only 5% of CN cases; the shoulder and elbow are most often involved, and the hip joint is rarely affected. As a rare factor, cervical spondylotic myelopathy (CSM) can be associated with syringomyelia, which is scarcely reported in the literature. Here, we present the first case report to date of CN of the hip caused by syringomyelia secondary to CSM. CASE SUMMARY: We describe a 76-year-old male patient who was diagnosed with CSM due to neck pain and weakness of limbs 16 years ago. Four years ago, he noticed recurrent swelling of the right hip with pain and was diagnosed with degenerative arthritis. Recently, however, his symptoms gradually worsened, and because of progressive pain, destabilization and weakness of the right hip, he was admitted to our hospital. Through systematic physical, radiographic and laboratory examinations, we finally reached a diagnosis: CN of the right hip associated with syringomyelia secondary to CSM. After comprehensive evaluation of the patient's condition, we performed right total hip arthroplasty. During the follow-up, the patient felt well clinically and could walk independently with a knee brace. CONCLUSION: We suggest a possible etiological association between CSM and syringomyelia, which may reflect a potential pathogenesis of CN. We encourage clinicians to actively carry out a detailed medical history and comprehensive physical and imaging examinations in patients with joint lesions, especially chronic shoulder neck pain, to rule out the possibility of this association, which plays a crucial role in the early diagnosis of CN. Arthroplasty may no longer be an absolute contraindication to surgical treatment of CN. Reasonable selection of the surgical strategy can markedly improve the clinical symptoms and quality of life of patients.

RESUMO

BACKGROUND: Recent innovations in intensive care have improved the prognosis of patients with severe brain injuries and brought more patients with disorders of consciousness (DoC). Data are lacking regarding the long-term outcomes of those patients in China. It is necessary to study the long-term outcomes of patients with prolonged DoC in light of many factors likely to influence crucial decisions about their care and their life. AIM: To present the preliminary results of a DoC cohort. METHODS: This was a two-center prospective cohort study of inpatients with vegetative state (VS)/unresponsive wakefulness syndrome (UWS). The study outcomes were the recovery from VS/UWS to minimally conscious state (MCS) and the long-term status of patients with prolonged DoC considered in VS/UWS or MCS for up to 6 years. The patients were evaluated using the Glasgow coma scale, coma recovery scale-revised, and Glasgow outcome scale. The endpoint of follow-up was recovery of full consciousness or death. The changes in the primary clinical outcome improvement in clinical diagnosis were evaluated at 12 mo compared with baseline. RESULTS: The study population included 93 patients (62 VS/UWS and 31 MCS). The post-injury interval range was 28-634 d. Median follow-up was 20 mo (interquartile range, 12-37 mo). At the endpoint, 33 transitioned to an emergence from MCS or full consciousness, eight had a locked-in syndrome, and there were 35 patients remaining in a VS/UWS and 11 in an MCS. Seven (including one locked-in syndrome) patients (7.5%) died within 12 mo of injury. Compared with the unresponsive group (n = 52) at 12 mo, the responsive group (n = 41) had a higher proportion of males (87.8% vs 63.5%, P = 0.008), shorter time from injury (median, 40.0 d vs 65.5 d, P = 0.006), higher frequency of vascular etiology (68.3% vs 38.5%, P = 0.007), higher Glasgow coma scale score at admission (median, 9 vs 6, P < 0.001), higher coma recovery scale-revised score at admission (median, 9 vs 2.5, P < 0.001), at 1 mo (median, 14 vs 5, P < 0.001), and at 3 mo (median, 20 vs 6, P < 0.001), lower frequency of VS/UWS (36.6% vs 90.0%, P < 0.001), and more favorable Glasgow outcome scale outcome (P < 0.001). CONCLUSION: Patients with severe DoC, despite having strong predictors of poor prognosis, might recover consciousness after a prolonged time of rehabilitation. An accurate initial diagnosis of patients with DoC is critical for predicting outcome and a long-term regular follow-up is also important.

RESUMO

Major evolutionary transitions are enigmas, and the most notable enigma is between invertebrates and vertebrates, with numerous spectacular innovations. To search for the molecular connections involved, we asked whether global epigenetic changes may offer a clue by surveying the inheritance and reprogramming of parental DNA methylation across metazoans. We focused on gametes and early embryos, where the methylomes are known to evolve divergently between fish and mammals. Here, we find that methylome reprogramming during embryogenesis occurs neither in pre-bilaterians such as cnidarians nor in protostomes such as insects, but clearly presents in deuterostomes such as echinoderms and invertebrate chordates, and then becomes more evident in vertebrates. Functional association analysis suggests that DNA methylation reprogramming is associated with development, reproduction and adaptive immunity for vertebrates, but not for invertebrates. Interestingly, the single HOX cluster of invertebrates maintains unmethylated status in all stages examined. In contrast, the multiple HOX clusters show dramatic dynamics of DNA methylation during vertebrate embryogenesis. Notably, the methylation dynamics of HOX clusters are associated with their spatiotemporal expression in mammals. Our study reveals that DNA methylation reprogramming has evolved dramatically during animal evolution, especially after the evolutionary transitions from invertebrates to vertebrates, and then to mammals.

RESUMO

Objective To explore the effects of whole-stage labor analgesia on maternal and neonatal outcomes after the implementation of the new partogram.Methods A retrospective cohort study was performed in Peking University First Hospital.From June to December 2016,907 nulliparae with full-term singleton cephalic pregnancies that were expected to deliver vaginally and adhered to the new partogram were selected as the study group,and 982 cases that adhered to the old partogram (Friedman standard) from June to December 2012 were selected as the control group.Maternal basic characteristics and analgesic,obstetric and neonatal data were collected.Maternal and neonatal outcomes between the two groups were analyzed with independent sample t-test,rank sum test or Chi-square test (Fisher's exact test).Results (1) Maternal age and the proportion of gravidas of advanced maternal age in the study group were both higher than those in the control group [(30.2±3.0) vs (29.64-2.9) years,t=3.823;8.2% (74/907) vs 4.2% (41/982),x2=13.087;both P<0.001].No statistically significant difference in the other basic characteristics was found between the two groups.(2) Women in the study group had significantly smaller cervical dilatation [M(P25-P75)] than that in the control group when analgesia was commenced [2(1-2) vs 2(1-3) cm,Z=-3.752].The intensity of pain quantified with numerical rating scale (NRS) before analgesia,and during the second stage of labor in the study group were less than that in the control group [8(8-9) vs 8(8-10) points,Z=-14.441;5(4-5) vs 6(5-7) points,Z=-16.495].The study group had longer median duration of analgesia than the control group [520(340-750) vs 300(200-453) min,Z=-17.801,P<0.001].The overall dose of analgesics in injection pump in the study group was significantly higher compared with that used in the control group [68 (35-84) vs 30 (18-48) ml,Z=-18.004,P<0.001].However,there was no significant difference in the incidence of analgesia-related complications (hypotension,accidental dura puncture,lower extremity numbness,pruritus and urinary retention) between the two groups.(3) The study group showed a higher percentage of spontaneous vaginal delivery,and a lower rate of converted cesarean section compared with the control group [71.8% (651/907) vs 63.2% (621/982),x2=15.623;13.6% (123/907) vs 20.5% (201/982),~=18.831;both P<0.001].The study group had lower forceps-assisted vaginal delivery rate than the control group without statistically significant difference [14.8% (133/907) vs 15.3% (150/982),x2=0.093,P=0.797].The duration of the first,second and third stage of labor in the study group were all significantly longer than that of the control group [680 (470-900) vs 480 (360-660) min,Z=-12.490;56 (31-89) vs 37 (24-58) min,Z=-9.964;7 (5-10) vs 6 (5-8) min,Z=-6.673;all P<0.001].Women in the study group had a lower rate of artificial rupture of membranes when comparing with the control group [55.2% (501/907) vs 63.2% (621/982),x2=12.516,P<0.001].The incidence of fever,pathologically confirmed infection and postpartum hemorrhage were significantly higher in the study group than that in the control group [10.8% (98/907) vs 6.4% (63/982),x2=11.652;9.6% (87/907) vs 3.7% (36/982),x2=27.201;12.6% (114/907) vs 5.7% (56/982),x2=27.144;all P<0.05].There was no significant difference in the rate of oxytocin use during labor or blood transfusion between the two groups.(4) Compared with the control group,the proportion of cesarean section due to arrested active stage of labor in the study group was significantly lower [5.7% (7/123) vs 50.2% (101/201),x2=68.173,P<0.05],but the incidences of cesarean section due to intrauterine infection and relative cephalopelvic disproportion were higher in the study group [61.0% (75/123) vs 30.8% (62/201),x2=2.680;20.3% (25/123) vs 8.0% (16/201),x2=10.555;both P<0.05].There was no significant difference in the proportion of fetal distress or other indications for cesarean section between the two groups.(5) There was no significant difference between the two groups in birth weight,macrosomia,fetal distress,neonatal asphyxia,or the proportion of neonatal intensive care unit admission.Conclusions After the implementation of the new partogram,analgesic pain relief covering the whole labor prolongs the average analgesic time and reduces the rate of cesarean section due to arrested active stage of labor.Although the risk of postpartum hemorrhage is slightly increased,analgesia itself does not pose additional risks on forceps-assisted delivery,maternal blood transfusion and neonatal asphyxia.

RESUMO

Objective: To discuss the application principle in tuina manipulation for lumbar intervertebral disc herniation (LIDH) in Chinese literatures published in recent 30 years. Methods: The three major Chinese databases, Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP) and China National Knowledge Infrastructure (CNKI), were searched to collect the studies of tuina manipulations in treatment of LIDH published in recent 30 years. Clustering analysis was applied to analyze the top 20 tuina manipulations for LIDH. Results: The top 20 most frequently used manipulations for LIDH were Gun-rolling, Rou-kneading, Dian-digital pressing, oblique Ban-pulling, An-pressing, Tanbo-plucking, Bashen-pulling and extending, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Dou-shaking, Yao-rocking, Ca-scrubbing, Pai-patting, post-extension Ban-pulling, Mo-rubbing, Zhen-vibrating, Nie-pinching, fist-back Ji-tapping, and dorsal Shen-extending methods. The involved manipulations can be divided into two categories by the treated body areas. One category is applied to the soft tissues, including Gun-rolling, Rou-kneading, Dian-digital pressing, An-pressing, Tanbo-plucking, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Ca-scrubbing, Pai-patting, Mo-rubbing, Zhen-vibrating, Nie-pinching, and fist-back Ji-tapping methods. The other category is applied to bones and joints, including oblique Ban-pulling, Bashen-pulling and extending, Dou-shaking, Yao-rocking, post-extension Ban-pulling, and dorsal Shen-extending methods. Conclusion: Based on the treated body area, the tuina manipulations applied to treat LIDH are predominated by the ones performed on soft tissues, assisted by those on bones and joints. From the way of force exertion, the involved manipulations are majorly the swinging methods, followed by squeezing and pressing ones. The manipulations applied to bones and joints are predominated by the Ban-pulling ones, followed by the Bashen-pulling and extending ones.

RESUMO

OBJECTIVE@#To analyze the predictive value of umbilical arterial cord pH on complications of hospitalized neonates after cesarean section.@*METHODS@#This was a retrospective cohort study and carried out in Peking University First Hospital from January 1, 2017 to June 30, 2017. Neonates who were delivered by cesarean section were enrolled. The primary endpoint was the incidence of complications during in-hospital stay (including infection, aspiration pneumonia, myocardial damage, etc.). The subjects were divided into two groups:with or without complication. The umbilical arterial cord pH values were compared between the two groups. Perinatal baseline characteristics of maternal and neonatal data were recorded. The ROC curve was used to analyze the value of umbilical arterial cord pH in predicting neonatal complications during hospitalization. Multivariate Logistic regression was employed to analyze the potential risk factors of neonatal complications.@*RESULTS@#In the study, 872 neonates were included in the final analysis (541 in elective surgery and 331 in emergency surgery). The overall incidence of neonatal complications during hospitalization was 14.1%. The first three higher incidences were infection, aspiration pneumonia and myocardial damage. The average pH value in neonates without complication was 7.31 while 7.29 in neonates with complication. There was statistical significance between the two groups (P<0.001). The overall incidence of pH≤7.20 was 3.1% (27/872). The patients in neonates without complication had higher incidence of pH≤7.20 than those in neonates with complication (1.6% vs. 12.2%, P<0.001). Multivariate Logistic regression showed 6 risk factors of neonatal hospitalized complications including preterm delivery (OR=8.224, 95%CI: 4.910-13.777, P<0.001), pregnancy-induced hypertension (OR=1.886, 95%CI: 1.004-3.546, P=0.049), intrauterine growth restriction (OR=4.429, 95%CI: 1.280-15.330, P=0.019), emergency cesarean section (OR=2.711, 95%CI: 1.682-4.369, P<0.001), umbilical arterial blood gas pH≤7.20 (OR=7.420, 95%CI: 2.951-18.655, P<0.001) and 5-minute Apgar score <10 scores (OR=11.849, 95%CI: 3.977-35.128, P<0.001). The areas under the ROC curve of umbilical arterial blood gas pH in all neonatal, elective and emergency cesarean section were 0.570 (95%CI: 0.508-0.633, P=0.012), 0.559 (95%CI: 0.465-0.652, P=0.189) and 0.617 (95%CI: 0.538-0.697, P=0.002), respectively.@*CONCLUSION@#Umbilical arterial cord pH≤7.20 was related with increased incidence of neonatal complications after cesarean section,but ROC curve analysis showed a lower predictive value.

RESUMO

OBJECT: MicroRNAs (miRNAs) play key roles in progression of cervical cancer. In the present study, we investigated the role of miR-214 in the process of migration, invasion and drug sensitivity to cisplatin in cervical cancer. METHODS: We detected the differential expression of miR-214 in 19 cases cervical cancer tissues and normal tissues as well as 4 cervical cancer cells and one normal cervical cells by Real-time PCR. Then, wound healing assay, transwell invasion assay and MTT were used to detect the effects of migration, invasion and sensitivity to cisplatin of cervical cancer when miR-214 was overexpressed. Western blot, immunofluorescence and Flow Cytometry were used to detect the mechanism of migration, invasion and sensitivity to cisplatin. Next, bioinformatics analysis was used to find the target of miR-214. Through the luciferase reporter assay, Real-time PCR and western blot, we confirmed the binding relationship of miR-214 and FOXM1. In cervical cancer tissues, the expression of FOXM1 was detected by western blot and Immunohistochemistry. We also knocked down FOXM1 in cervical cancer cells, wound healing assay, transwell invasion assay and MTT were performed to detect the migration, invasion and sensitivity to cisplatin abilities of FOXM1. Western blot and Flow Cytometry were used to detect the mechanism of migration, invasion and sensitivity to cisplatin by FOXM1. Finally, we performed rescue expriments to confirm the function relationship between miR-214 and FOXM1. RESULTS: 1. Our results showed that miR-214 was frequently downregulated in tumor tissues and cancer cells especially in CIN III and cervical cancer stages. 2. Overexpression of miR-214 significantly inhibited migration and invasion of cervical cancer cells and prompted the sensitivity to cisplatin. 3. FOXM1 was identified as a target of miR-214 and down-regulated by miR-214. 4. Knocking down FOXM1 could inhibited migration and invasion of cervical cancer cells and prompted the sensitivity to cisplatin. 5. FOXM1 was upregulated in tumor tissues. 6. The mechanism of migration, invasion and sensitivity to cisplatin were the resluts of changes of EMT and apoptosis. 7. The restoration of FOXM1 expression can counteract the effect of miR-214 on cell migration, invasion and sensitivity to cisplatin of cervical cancer cells. CONCLUSIONS: These findings indicate that miR-214 acts as a tumor suppressor during the process of migration, invasion and drug sensitivity through targeting FOXM1, suggesting miR-214 as a potential new diagnostic and therapeutic target for the treatment of cervical cancer.

RESUMO

B-phycoerythrin (B-PE) was separated and purified from microalga Porphyridium cruentum using one-step chromatographic method. Phycobiliproteins in P. cruentum was extracted by osmotic shock and initially purified by ultrafiltration. Further purification was carried out with a SOURCE 15Q exchange column and analytical grade B-PE was obtained with a purity ratio (A545/A280) of 5.1 and a yield of 68.5%. It showed a double absorption peaks at 545 nm and 565 nm and a shoulder peak at 498 nm, and displayed a fluorescence emission maximum at 580 nm. The analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) showed a bulky band between 18 and 20 kDa which could be assigned to subunits α and ß and a low intensity band of 27 kDa assigned to γ subunit. Our protocol provides attractive alternative to consider for the purification procedure to obtain analytical grade B-PE at commercial level.

RESUMO

The residual consciousness of unconscious patients can be detected by studying the P300, a wave among event-related potentials. Previous studies have applied tones, the subject's name and other names as stimuli. However, the results were not satisfactory. In this study, we changed the constituent order of subjects' two-character names to create derived names. The subject's derived names, together with tones and their own names, were used as auditory stimuli in event-related potential experiments. Healthy controls and unconscious patients were included in this study and made to listen to these auditory stimuli. In the two paradigms, a sine tone followed by the subject's own name and the subject's derived name followed by the subject's own name were used as standard and deviant stimuli, respectively. The results showed that all healthy controls had the P300 using both paradigms, and that the P300 in the second paradigm had a longer latency and two peaks. All minimally conscious state patients had the P300 in the first paradigm and the majority of them had the P300 in the second paradigm. Most vegetative state patients had no P300. Patients who showed the P300 in the two paradigms had more residual consciousness, and patients with the two-peak P300 had a higher probability of awakening within a short time. Our experimental findings suggest that the P300 event-related potential could reflect the conscious state of unconscious patients.

RESUMO

Objective To investigate the influence of biological rhythm on labor pain,epidural analgesia and delivery mode in parturients.Methods In this retrospective cohort study,3 571 Chinese nulliparas with term singleton cephalic pregnancy who were preparing to deliver vaginally and receive epidural analgesia,were included.Parturients were divided into four groups according to the beginning time of analgesia,i.e.,morning group (7:01 to 13:00,n=955),afternoon group (13:01 to 19:00,n=1 159),evening group (19:01 to 1:00,n=763),and night group (1:00 to 7:00,n=694).Pain scores were assessed using a numeric rating scale (NRS) before and after epidural analgesia.Delivery mode,incidence of adverse events and neonatal outcomes were also compared among the four groups with monovariance analysis,LSD,Chi-square test or Fisher's exact test,Bonferroni,General Linear Model (GLM) and Logistic regression analysis.Results (1) The NRS pain scores of morning,afternoon,evening and night groups before analgesia were 8.6± 1.0,8.8± 1.0,8.9± 1.0 and 8.7± 1.0,respectively.After adjusted by GLM,the NRS pain scores of the four groups were 8.6±0.0,8.8 ± 0.0,8.9±0.0 and 8.7±0.0,respectively.Univariate and multivariable analyses showed that pain scores before analgesia were higher in afternoon group than in morning group (P<0.01),and they were significantly higher in evening group than in morning and night groups (all P<0.05).(2) At 10 and 30 minutes after epidural analgesia,the NRS pain scores of the four groups were 4.3± 1.0 and 1.8±0.9,4.8± 1.0 and 2.1 ±0.9,4.9± 1.1 and 2.2± 1.0,and 4.4± l.l and 1.8± 1.0,respectively,which were also significantly higher in afternoon and evening groups than in morning and night groups (all P < 0.01 or 0.05) ; and the proportions of analgesia satisfaction (NRS pain score ≤ 3) were 19.7% (188/955) vs 97.4% (930/955),11.6% (134/1 159) vs96.0% (1 113/1 159),11.3% (84/743) vs95.2% (707/743),18.7% (130/694) vs 95.6% (670/694),respectively,which were significantly lower in afternoon and evening groups than in morning and night groups (all P<0.01 or 0.05).(3) Delivery mode,incidence of adverse events and neonatal outcomes were similar among the four groups.Conclusions More severe labor pain before analgesia occur in parturients who receive epidural analgesia in the afternoon and at night,and less efficient analgesia and a lower rate of satisfaction are observed at 10 and 30 minutes after analgesia.However,delivery mode,neonatal outcomes and incidence of adverse events are not influenced by biological rhythm.

RESUMO

By taking "lumbar disc herniation", Chinese medicine", "acupuncture and moxibustion" as key words Chinese articles about acupuncture for lumbar disc herniation in recent 10 years were searched in three major Chinese databases of Wan fang database, VIP database and CNKI. Totally 546 relative articles were retrieved. After the elimination of invalid articles, 173 were included as valid articles with 49 main acupoints. The hierarchical clustering statistical method was used to analyze the possible rules among the former 20 acupoints. It turned out that there were 10 most common used acupoints on Bladder Meridian [Geshu (BL 17), Xiaochangshu (BL 27), Shenshu (BL 23), Dachangshu (BL 25), Pangguangshu (BL 28), Guanyuanshu (BL 26), Weizbong (BL 40), Zhibian (BL 54), Chengshan (BL 57), Kunlun (BL 60)], 2 on Gallbladder Meridian [Huantiao (GB 30), Yanglingquan (GB 34)], 2 on Governor Vessel [Yaoyangguan (GV 3), Shuigou (GV 26)], 2 on Stomach Meridian [Zusanli (ST 36), Juliao (ST 3)], 2 on Spleen Meridian [Sanyinjiao (SP 6), Xuehai (SP 10)], and the rest were extra points (Huatuo Jiaji) and Ashi points, so a conclusion could be drawn that the most common used acupoints were Bladder Meridian acupoints and supplemented by Gallbladder Meridian, Governor Vessel, Stomach Meridian, Spleen Meridian, extra points and Ashi points. The selected acupoints were most located on the lumbosacral region, leg and fewer located on the face, back and local part.

RESUMO

OBJECTIVE: To observe the efficacy differences among acupuncture at Neiguan (PC 6) and Zusanli (ST 36), dolantin and scopolamine in treatment of acute renal colic, and to verify the clinical effect of acupuncture at Neiguan (PC 6) and Zusanli (ST 36). METHODS: Two hundred and forty patients were randomly divided into an acupuncture group, a scopolamine group and a dolantin group, 80 cases in each group. The acupuncture group was treated by acupuncture at unilateral or bilateral Neiguan (PC 6) and Zusanli (ST 36). The scopolamine group was treated by intramuscular injection of scopolamine combined with intravenous drip of scopolamine, and the dolantin group was treated by intramuscular injection of dolantin. The clinical therapeutic effects were observed 30 min after drug administration or acupuncture, and the onset time of effect and adverse reactions were compared among the groups. RESULTS: The total effective rate of 95.0% (76/80) in the acupuncture group had a similar therapeutic effect to 92.5% (74/80) in dolantin group (P>0.05), which were both superior to 76.3% (61/80) in scopolamine group (both P<0.05). The onset time of (13.24 +/- 2.12) min in the acupuncture group was significant earlier than (23.11 +/- 6.22) min in scopolamine group and (22.17 +/- 3.15) min in dolantin group (both P<0.05), and compared with the other two groups, the adverse reactions in the acupuncture group were significant decreased (both P<0.05). CONCLUSION: Acupuncture at Neiguan (PC 6) and Zusanli (ST 36) has a good analgesic effect with a low incidence of adverse reactions, which is superior to that of dolantin and scopolamine.

RESUMO

OBJECTIVE: To investigate the effects of serum containing Yiqi Huayu Bushen Recipe, a compound Chinese herbal medicine, on expressions of aggrecan and type X collagen mRNAs of the degenerated intervertebral disc cells in patients with cervical spondylotic myelopathy. METHODS: Six inpatients diagnosed as cervical spondylotic myelopathy and undergoing cervical decompression and fusion surgery to remove the degenerated disc tissue were enrolled in this study. Primary intervertebral disc cells were isolated using small tissue mass method. Serum containing Yiqi Huayu Bushen recipe were obtained after SD rats were fed with Yiqi Huayu Bushen recipe for 3 days. MTT method was used to detect proliferation of the first-passage cells isolated from degenerated intervertebral discs and growth curve was drawn. In the following tests, the first-passage cells were cultured with the sera containing drugs and sodium chloride (NaCl), respectively. Proliferation of intervertebral disc cells was detected by MTT method and expressions of aggrecan and type X collagen mRNAs were detected by real-time polymerase chain reaction. RESULTS: The growth curve of the first-passage cells of the degenerated intervertebral discs showed that the time of cell proliferation peak was the sixth day. Compared with the same concentrations of NaCl solution, serum containing Yiqi Huayu Bushen Recipe at 5%, 10% and 20% promoted cell proliferation and expression of aggrecan mRNA and decreased expression of type X collagen mRNA (P<0.01). 10% serum containing Yiqi Huayu Bushen recipe was more effective than 5% and 20%. CONCLUSION: Yiqi Huayu Bushen Recipe inhibits degeneration of the intervertebral disc cells by regulating collagen and proteoglycan expressions.
