RESUMO

To evaluate the application of outcome indicators in randomized controlled trials(RCTs) concerning the treatment of tension-type headache(TTH) with traditional Chinese medicine(TCM) in recent five years, so as to provide a basis for the study of core outcome set(COS) for TCM intervention in TTH. The RCTs on TCM treatment of TTH in recent five years were systematically retrieved from CNKI, Wanfang, VIP, CBM, EMbase, PubMed, Cochrane Library, Web of Science, ClinicalTrials.gov and China Clinical Trial Registry. After literature screening, data extraction and evaluation of the risk of bias, the outcome indicators in the included RCTs were subjected to qualitative analysis. The preliminary search yielded 19 042 articles, and 10 983 were left after the elimination of duplication. Finally, 52 RCTs(48 in Chinese and 4 in English) were included for qualitative analysis. The outcome indicators of RCTs included in this study were classified into seven domains: TCM syndrome, symptom and sign, physical and chemical detection, quality of life, long-term prognosis, economic evaluation, and safety event. The findings demonstrated that headache characteristic index in the symptom and sign domain was the index with the highest reporting frequency and reporting rate. Seventeen RCTs used TCM syndrome score as the outcome indicator. Further analysis revealed that there existed such problems in research design as non-distinction between primary and secondary outcome indicators, great difference in the adopted measurement tools for outcome indicators, and the neglect of measurement time of outcome indicators. Moreover, the syndrome indicators reflecting TCM advantages, objective evaluation indicators, safety and health-economic indicators were lacking. These limitations have affected the quality and reliability of RCTs on TTH treatment with TCM. It is suggested that the efficacy and characteristics of TCM should be combined into current clinical research, and the COS in RCTs regarding TCM treatment of TTH should be established according to internationally recognized standard procedures.

RESUMO

The efficacy of gastrodin as a Chinese herbal medicine extract in the treatment of tension-type headache has been confirmed. This paper systematically reviewed the efficacy and safety of gastrodin in the treatment of tension-type headache, aiming to provide a new choice for the treatment of this disease. In this study, four Chinese databases, four English databases and two trial registries were searched from the date of establishment to September 2020. The related randomized controlled trials(RCTs) were screened out according to the predetermined criteria. The bias risk assessment tool developed by Cochrane collaboration was used to evaluate the quality of the reports. RevMan 5.4.1 was used for Meta-analysis, and GRADE system for the evidence-based evaluation on the quality of outcome indicators. A total of 177 articles were retrieved and 8 articles were finally included for analysis, with a total sample size of 1 091 cases, which included 565 cases in the treatment group and 526 cases in the control group. The overall quality of included stu-dies was not high. The results of Meta-analysis are as follows:(1)In terms of headache frequency, gastrodin group was better than wes-tern medicine group(MD=-2.90, 95%CI[-3.76,-2.03], P<0.000 01).(2)In terms of number of abnormal blood vessels in TCD, gastrodin group was better than western medicine group(MD=-88.96, 95%CI[-102.36,-75.55], P<0.000 01).(3)In terms of effective rate, gastrodin group was better than western medicine group(RR=1.47, 95%CI[1.29, 1.68], P<0.000 01). The results of subgroup analysis are as follows:(1)Effective rate based on age, for the patients upper age limit 40-46 years old, gastro-din group was better than western medicine group(RR=1.69, 95%CI[1.50, 1.90], P<0.000 01); for the patients upper age limit 55-60 years old, gastrodin group was better than western medicine group(RR=1.27, 95%CI[1.16, 1.38], P<0.000 01).(2)Effective rate based on dosage form, both the gastrodin capsules and injection groups were better than western medicine group(RR_(capsules)=1.42, 95%CI[1.08, 1.88], P=0.01; RR_(injection)=1.50, 95%CI[1.26, 1.77], P<0.000 01). GRADE evaluation showed that the above outcomes had low quality of evidence. Only one article detailed the occurrence of adverse reactions and thus the present study cannot make a positive conclusion on the safety of gastrodin in the treatment of tension-type headache. The small number and low quality of the included reports affected the reliability of the results. In the future, more high-quality randomized controlled trails are needed to improve the evaluation on the efficacy and safety of gastrodin in the treatment of tension-type headache.

RESUMO

This study aims to systematically evaluate the clinical efficacy and safety of Toutongning Capsules in the treatment of tension-type headache(TTH), so as to provide a corresponding basis for clinical treatment. Eight commonly used medical research databases and two clinical trial registration systems were retrieved with the time interval from the establishment of the database or system to November 2020. The randomized controlled trials of Toutongning Capsules in the treatment of TTH were screened out according to the pre-set criteria. The quality of the included papers was evaluated by the bias risk assessment tool in Cochrane Reviewers Handbook 6.1 and the data were statistically analyzed by RevMan v5.4 provided by Cochrane collaboration. A total of 13 studies were included and the quality of methodology was generally low. Meta-analysis showed that Toutongning Capsules assisted with western medicine therapy can effectively reduce the pain intensity(MD_(VAS)=-1.94,95%CI[-2.50,-1.38],P<0.000 01;MD_(NRS)=-0.83,95%CI[-0.86,-0.80],P<0.000 01), headache duration(SMD=-0.98,95%CI[-1.17,-0.79],P<0.000 01), headache frequency(MD=-1.01,95%CI[-1.16,-0.85],P<0.000 01), headache index(MD=-11.13,95%CI[-12.10,-10.16],P<0.000 01), anxiety and depression scale score(MD_(HAMA)=-4.02,95%CI[-6.58,-1.46],P=0.002;MD_(HAMD)=-2.67,95%CI[-4.04,-1.29],P=0.000 1), while Toutongning Capsules as monotherapy only reduced the headache score(MD=-2.24,95%CI[-2.97,-1.51],P<0.000 01). The available clinical studies demonstrate that Toutongning Capsules combined with western medicine in the treatment of TTH can improve the related outcome indicators, but the clinical safety and efficacy of Toutongning Capsules alone remain unclear. Due to the small number and low quality of the included studies, large-sample, multi-center, high-quality and strictly designed randomized controlled trials are still needed to verify the clinical efficacy in the future.

RESUMO

OBJECTIVE: To analyze velopharyngeal closure patterns and speech characteristics of patients with congenital velopharyngeal insufficiency. METHODS: Patients visiting the Department of Cleft Lip and Palate Surgery, West China Hospital of Stomatology, Sichuan University between 2009 and 2017 were reviewed. Outcomes of subjective speech evaluation, including resonance, consonant articulation, and correction rate, were analyzed. Furthermore, the mobility of soft palate and pharyngeal walls under nasopharyngeal fiberscope were analyzed retrospectively. RESULTS: A total of 47 cases were retrieved and subjected to nasopharyngeal fiberscopic examination. Among them, 29 (61.7%) demonstrated a circular closure pattern, 16 (34.0%) showed a coronal pattern, and 2 (4.3%) had a sagittal pattern. Furthermore, 25 (53.2%) presented medium soft-palate mobility, 22 (46.8%) had weak lateral pharyngeal wall mobility, and 41 (87.2%) had no posterior pharyngeal wall mobility. Among all of the patients, 23 (48.9%) presented medium hypernasality, accounting for the highest proportion. Consonant misarticulation occurred in 89.4% of the cases. The articulation manners with the highest correction rate were in the following order: nasal, lateral, fricatives, stops, and affricates. The articulation places with the highest correction rate were in the following order: bilabial, alveolar, velar, and linguadental. CONCLUSIONS: Circular closure was the most prevalent velopharyngeal closure pattern among patients with congenital velopharyngeal insufficiency, and consonant omission was the most common articulation abnormality.

RESUMO

Lectin receptor-like kinases (LecRLKs) are a class of membrane proteins found in plants that are involved in diverse functions, including plant development and stress responses. Although LecRLK families have been identified in a variety of plants, a comprehensive analysis has not yet been undertaken in cucumber (Cucumis sativus L.). In this study, 46 putative LecRLK genes were identified in the cucumber genome, including 23 G-type and 22 L-type, and one C-type LecRLK gene. They were unequally distributed on all seven chromosomes, with a clustering tendency. Most of the genes in the cucumber LecRLK (CsLecRLK) gene family lacked introns. In addition, there were many regulatory elements associated with phytohormones and stress on these genes' promoters. Transcriptome data demonstrated distinct expression patterns of CsLecRLK genes in various tissues. Furthermore, we found that each member of the CsLecRLK family had its own unique expression pattern under hormone and stress treatment by the quantitative real-time PCR (qRT-PCR) analysis. This study provides a better understanding of the character and function of the LecRLK gene family in cucumber and opens up the possibility to exploring the roles that LecRLKs might play in the life cycle of cucumber.

RESUMO

OBJECTIVE: This research aims to collect speech samples from patients with cleft palate, establish a mandarin-based database of cleft palate speech after sample analysis and classification, and provide a reference for the diagnosis of hypernasal or cleft palate, clinical education, and standard training for professional speech therapists and related research. METHODS: A total of 768 speech samples were collected from patients and volunteers from the Speech Therapy Center, West China Hospital of Stomatology, between May 2016 and March 2018. These samples were edited and categoried before being saved into the cleft lip and palate biologic information database. RESULTS: A mandarin-based database of cleft palate speech was established from 768 subjects, including 456 children (male 227, female 229), 312 adults (male 178, female 134), 369 normal speech voices, 155 low-level hypernasal samples, 102 moderate-level hypernasal samples, 142 high-level hypernasal samples, and 64 512 words, 24 576 phonemes, and 7 680 numbers. CONCLUSIONS: This study first established a mandarin-based database of cleft palate speech, which has enormous value for the education of speech pathology of cleft palate in mandarin and further research.

RESUMO

OBJECTIVE: To demonstrate the regularity of velopharyngeal function recovery after primary cleft palatoplasty and its correlation with different surgical procedures, ages, cleft types, and follow-up times. METHODS: Patients with cleft palate under 5 years old who had more than two follow-up records were included in this study, and consecutive evaluations of postoperative velopharyngeal function were performed. Univariate and multivariate logistic regression analysis were used to reveal the regularity of postoperative velopharyngeal function and the possible influencing factors. RESULTS: A total of 165 patients were included. Inconsistent functions of the velopharyngeal closure were observed in 31 patients, of which velopharyngeal insufficiency (VPI) in the first follow-up converted to velopharyngeal competence (VPC) in the second follow-up, accounting for 18.79% of the total, and 134 patients had consistent velopharyngeal function. The patients in the group who had consistent velopharyngeal function were younger than those in the group who were inconsistent, and the differences between the two groups were statistically significant. The younger the operation age, the patient's velopharyngeal function was more likely to stabilize at the first follow-up. At the time of the first follow-up in 15, 28, and 40 months, the probability that the patients had stable postoperative velopharyngeal function was 80%, 90%, and 95%, respectively. CONCLUSIONS: The recovery of velopharyn-geal function after surgery is a dynamic process. The velopharyngeal status of patients can be converted from VPI to VPC. Meanwhile, VPC cannot switch to VPI. The follow-up time is the most important factor affecting the consistency of the evaluation of velopharyngeal function. Choosing appro-priate follow-up time is the key to obtain the stable evaluation of velopharyngeal function.

RESUMO

We have successfully enhanced the performance of commercial supercapacitors that use Japan Kuraray 80F activated carbon and Super-P conductive carbon black as the conductive agent with reduced graphene oxide (rGO) additive. The ratios of conductive carbon black to rGO studied are 3:1, 5:1, 10:1, 15:1 and 1:0. The enhancement is most pronounced at 15:1, and the specific capacitance being 137.5 F g-1, which is a 23.8% improvement over the 1:0 control. The specific capacitance retention is 70.1% after 10000 cycles. The impedance resistance is also reduced to 1.5 Ω, which is 3.3 times lower than the 1:0 control. Additionally, the rGO additive does not alter the favorable pore size distribution of the primary matrix and successfully preserves its small mesoporous structure, which facilitates facile transport of electrolyte.

RESUMO

OBJECTIVE: To explore the prognostic factors affecting the primary surgical management of aged patients with cleft palate. METHODS: This study reviewed aged patients with cleft palate who received Furlow palatoplasty (surgical age≥5 years) at the cleft center at West China Hospital of Stomatology from 2009 to 2014. The study retrieved intraoperative mea-surements, including velar length, pharyngeal depth, cleft width, maxillary width, cleft palate index, and palatopharyngeal ratio. Speech evaluation results at follow-up at least a year after surgery were also obtained. Logistic regression and retrospec-tive analyses were performed to identify correlative prognostic factors. RESULTS: One hundred and thirty-one patients were included (70 males and 61 females). Dichotomy logistic regression analysis revealed that pharyngeal depth was the only mea-surement considerably associated with postoperative velopharyngeal function. Pharyngeal depth deeper than 16 mm indicated high risk of postoperative velopharyngeal insufficiency. CONCLUSIONS: Pharyn-geal depth is a significant prognostic factor for the primary surgical management of aged patients with cleft palate. Pharyn-goplasty might be considered when planning the primary management of aged patients.

RESUMO

OBJECTIVE: The varying width ratio patterns of posterior hard palate cleft to posterior maxillary tuberosity plane and their relationship with growth and development were studied in specific-age patients with simple cleft palate before surgery to provide a reference for evaluating operation difficulty and predetermining operative period. METHODS: A total of 581 patients with simple cleft palate who received surgical treatment and are aged 8 months to 38 years participated in this study. All patients were categorized into seven groups based on age at preoperative measurement. The widths of posterior maxillary tuberosity plane and hard palate cleft were selected from the preoperative direct measurements. The relative width ratio of the hard palate to posterior maxillary tuberosity plane in each patient was used to objectively reflect the relative width of cleft palate. RESULTS: For patients with simple cleft palate, the widths of posterior maxillary tuberosity plane and hard palate showed remarkably increasing trends. CONCLUSIONS: The transverse proportion of cleft palate fissure in the upper mandible increases statistically with age, suggesting the need for complex operation.

RESUMO

INTRODUCTION: Ectopic liver (EL) is a rare entity, which is reported to develop at various sites, such as the abdominal cavity, the retroperitoneal cavity, the pleural cavity, and the mediastinum. PATIENT CONCERNS: A 27-year-old previously healthy Chinese man suffered from a discontinuous abdominal pain in the upper abdomen for 2 months. DIAGNOSIS: The upper gastrointestinal endoscopy revealed there was a polypoid mucosal uplift on the distal region of the esophagus near the cardia. INTERVENTIONS: Endoscopic polypectomy was performed. OUTCOMES: Pathology examination showed the liver tissue. CONCLUSION: EL should be excised as it may possibly lead to the development of a malignancy. Endoscopic resection was found to be safe and reliable in this case.

RESUMO

OBJECTIVE: To analyze the training technique, intervention timing, and other related factors involved in the speech therapy delivered to cleft patients with velopharyngeal competence after surgery. METHODS: A retrospective study was conducted on 32 patients who received phonology-articulation speech therapies during 2012 to 2013 in Dept. of Cleft Lip and Palate, West China Hospital of Stomatology, Sichuan University. All patients achieved normal speech one year after therapy. Information collected included the types and number of consonant articulation error, the overall period of training, the interval between surgery and speech training, and the age during speech training. Statistical analyses were performed in SPSS 16.0. RESULTS: Ten patients received less than five sessions of training, seventeen received six to ten sessions, and five received eleven to twenty sessions. The number of sessions was positively correlated with the number of errors (r(s)=0.394, P=0.026). On the average, each additional error cost another 0.570 session for correction (confidence interval: 0.137-1.004). Moreover, the number of sessions was negatively correlated with age (P=0.055). Patients between 5 to 10 years old took significantly lesser sessions than those above 10 years. No correlation was found between the number of sessions and the interval between surgeries and trainings. CONCLUSIONS: Appropriate speech therapy efficiently rehabilitate the speech condition of cleft patients with velopharyngeal sufficiency after surgery. The number of errors is directly proportional to the number of sessions needed. Patients above 10 years require more sessions than those less than 10 years.

RESUMO

High-density genetic linkage map plays an important role in genome assembly and quantitative trait loci (QTL) fine mapping. Since the coming of next-generation sequencing, makes the structure of high-density linkage maps much more convenient and practical, which simplifies SNP discovery and high-throughput genotyping. In this research, a high-density linkage map of cucumber was structured using specific length amplified fragment sequencing, using 153 F2 populations of S1000 × S1002. The high-density genetic map composed 3,057 SLAFs, including 4,475 SNP markers on seven chromosomes, and spanned 1061.19 cM. The average genetic distance is 0.35 cM. Based on this high-density genome map, QTL analysis was performed on two cucumber fruit traits, fruit length and fruit diameter. There are 15 QTLs for the two fruit traits were detected.

RESUMO

KEY MESSAGE: Using map-based cloning of Tril gene, we identified a homeodomain-leucine zipper gene involved in the initiation of multicellular trichomes (including the spines of fruit) in cucumber. ABSTRACT: Fruit spines are a special type of trichome that impacts the quality and appearance of cucumber (Cucumis sativus L.) fruit. Scanning electron microscopy revealed that the trichome-less (tril) mutant originating from European greenhouse cucumber has a completely glabrous phenotype on cotyledons, hypocotyls, young leaves, fruits, and fruit stalks. Genetic analysis revealed that tril was inherited as a recessive allele at a single locus. Using 1058 F2 individuals derived from a cross between cucumber tril mutant CGN19839 and the micro-trichome (mict) mutant 06-2, tril was mapped to chromosome 6, and narrowed down to a 37.4 kb genomic region which carries seven predicted genes. Genetic and molecular analyses revealed that gene Cucsa.045360 is a possible candidate gene for the differentiation of epidermal cells to trichomes. It is a member of the class IV homeodomain-leucine zipper (HD-Zip IV) family and encodes homeodomain and START domain, sharing 66.7% predicted amino acid sequence identity to PROTODERMAL FACTOR2 (PDF2) and 35.0% to GLABRA2 (GL2) of Arabidopsis. The homeobox domain had changed amino acid sequence because of an insertion in tril mutant. The results of genetic analysis and transcriptome profiling indicated that the Tril gene had an epistatic effect on the Mict gene in trichome development. Phenotypes of the tril mutant such as glabrous fruits and female flowers at every node could be used in developing new cultivars.

RESUMO

Previous studies have indicated that neurons in the dorsomedial hypothalamic nucleus (DMN) receive feeding-related signals from the gastric vagal nerves, glycemia as well as leptin. On the other hand, it is intriguing that the cerebellum participates in regulating nonsomatic visceral activities including food intake via the direct cerebellohypothalamic projections. The present study was designed to examine, by using extracellular recordings in vivo in rats, whether the cerebellar fastigial nucleus (FN) could reach and converge with the feeding-associated gastric vagal, glycemia and leptin signals onto single DMN neurons. Of the 200 DMN neurons recorded, 104 (52%) responded to the cerebellar FN stimulation, in which 95 (91.3%) were also responsive to the gastric vagal stimulation, suggesting a convergence of cerebellar FN and gastric vagal inputs on the DMN neurons. Moreover, a summation of responses was observed (n = 10) when the cerebellar FN and gastric vagal nerve were simultaneously stimulated. Among the 18 DMN neurons receiving convergent inputs from the cerebellar FN and gastric vagal nerves, 16 (88.9%) cells also responded to the systemic administrations of glucose and leptin. These results demonstrated that the cerebellar FN-afferent inputs, together with the feeding signals from the gastric vagal nerves, blood glucose as well as leptin, converge onto single DMN neurons, suggesting that a somatic-visceral integration related to the feeding may occur in the DMN and the cerebellum may actively participate in the feeding regulation through the cerebellar FN-DMN projections.

RESUMO

Several studies have implicated the dorsomedial hypothalamic nucleus (DMN) in regulation of feeding behavior and body weight, but clear mechanisms by which it controls food intake are not well understood. We report the results of the present study, which showed that the DMN receives important peripheral short- and long-term feeding-related afferent signals, including gastric vagal, glycemia, and cholecystokinin (CCK) inputs, as well as from leptin, an adipostatic signal that forcefully inhibits food intake and increases metabolic rate. Among the 279 DMN neurons recorded, 173 (62.0%) responded to stimulation of gastric vagal nerves. Also, of the 123 DMN neurons responsive to gastric vagal stimulation that were tested with the administration of intravenous glucose, 75 (61.0%) were identified as being glycemia sensitive. Moreover, it is noteworthy that of the 23 DMN neurons that responded to both gastric vagal and intravenous glucose stimulation, most (19 of 23, 82.6%) were sensitive to circulating leptin, and some neurons (n = 7) were also responsive to systemic CCK, suggesting that gastric vagal, glycemic, CCK, and leptin inputs converge on single DMN neurons. Furthermore, synergistic interactions between leptin and glucose on single DMN neurons were observed (n = 6). These results demonstrate that those important peripheral feeding-related gastric vagal, glycemic, CCK and leptin signals not only reach the DMN but also interact on single DMN neurons, suggesting that the DMN may not just function as a relay station, but independently integrate the short-term and long-term feeding-associated information and actively participate in the direct regulation of feeding behavior.

RESUMO

The economic traits of Liaoning new breed of cashmere goats, a special Chinese genetic resource, were analyzed in 150 animals by typing 11 microsatellite loci. The association between three economic traits (body weight, cashmere yield and fineness) in this new breed of goats and the marker genotypes were analyzed. The results show that: AA and BC at LSCV13, DE at IDVGA64 and BB at BMS2782 were favorable genotypes for body weight. AB at LSCV13, AD and BE at CSSM11, BD and CC at IDVGA64, BC and DE at BMS2782 were favorable genotypes for cashmere yield. AA at CSSM11, BC and DE at IDVGA64, CD at BMS2782 were favorable genotypes for cashmere fineness.
