Objective To systematically analyze the current status of outcomes reporting in clinical trials on treating stasis acute mastitis with Traditional Chinese Medicine breast massage.Methods We searched CNKI, Wanfang, VIP, SinoMed, PubMed, Web of Science, Embase, Cochrane library, JBI, CINAHL, PsycINFO, Clinical Trials Registry Platform portal, Clinical Trials Registry, Australian New Zealand Clinical Trials Registry, Center Watch Registry from inception to May 15, 2022 to find randomized controlled trials, non-randomized controlled trials, case series and cohort studies which reported the outcomes of stasis acute mastitis managed with Traditional Chinese Medicine breast massage, with search terms of mastitis, acute mastitis, lactation mastitis, puerperal mastitis, breast problem, breast engorgement, milk stasis, blocked ducked, breast pain, breast massage, and acupoint massage. Outcomes and the measurement schemes (measurement methods, timing of assessing outcome, frequency of assessing outcome, measurers) were extracted from the included studies. We used the Management of Otitis Media with Effusion in Children with Cleft Palate (MOMENT) to assess the quality of each study, then categorized outcomes derived from the included studies into different domains according to the Outcome Measures in Rheumatology Arthritis Clinic Trials (OMERACT) Filter 2.1 framework.Results We identified 85 clinical trials, in which 54 different outcomes were reported. A total of 81.2% (69/85) of studies were assessed as medium quality with a mean score of 2.6, and 18.8% (16/85) as low quality with a mean score of 0.9. These outcomes were organized in three core areas. Lump size (89.4%, 76/85) was the most frequently reported outcome, followed by breast pain (69.4%, 59/85) and milk excretion (68.2%, 58/85). Five methods were used to assess lump size and four methods to assess breast pain.Conclusions The outcomes reported in clinical trials regarding stasis acute mastitis treated by Traditional Chinese Medicine breast massage are heterogeneous. Developing a core outcome set to achieve consistent standards for reporting outcomes and modalities for validation of the outcomes is clearly warranted.

OBJECTIVE: To predict the learning curve of tooth preparation for all ceramic crowns of maxillary central incisors on phantom head simulators for graduate students participating in standardized dental resident training based on the modified Wright learning curve model, then to analyze and applicate the learning curve. METHODS: Twelve graduate students participating in standardized dental resident training were selected to prepare the resin maxillary central incisors on phantom head simulators for all ceramic crowns 4 times. The results of preparation were evaluated by 3 prosthetic experts with at least 10 years' experience focusing on the reduction, contour, taper, shoulder, finish line, margin placement, adjacent tooth injury, and preparation time for tooth preparation. The learning rate of tooth preparation was calculated by scores of tooth preparation of 4 times. The learning curve of tooth preparation was predicted based on the modified Wright learning curve model. According to the criteria of standardized training skill examinations for dental residents in Beijing, 80 was taken as the qualified standard score. The minimum training times for tooth preparation to satisfy the qualified standard score (80) was calculated, to analyze the characteristics of learning curve and evaluate the effectiveness of tooth preparation. RESULTS: The scores of 4 tooth preparation were 64.03±7.80, 71.40±6.13, 74.33±5.96, and 75.98±4.52, respectively. The learning rate was (106±4)%, which showed the learning curve an upward trend. There were no significant differences between the qualified standard score and the predicted scores of tooth preparation from the 5^th preparation to the 13^th preparation (P > 0.05). The predicted score of the 14^th preparation was higher than the qualified standard score (P < 0.05). CONCLUSION The trend of the learning curve of tooth preparation for all ceramic crowns of maxillary central incisors on phantom head simulators for graduate students participating in standardized dental resident training is upward, which predicts the minimum training times higher than the qualified standard score is 14 times.

OBJECTIVE: To estimate the univariate heritability of resting heart rate and common chronic disease such as hypertension, diabetes, and dyslipidemia based on extended pedigrees in Fujian Tulou area and to explore bivariate heritability to test for the genetic correlation between resting heart rate and other relative phenotypes. METHODS: The study was conducted in Tulou area of Nanjing County, Fujian Province from August 2015 to December 2017. The participants were residents with Zhang surname and their relatives from Taxia Village, Qujiang Village, and Nanou Village or residents with Chen surname and their relatives from Caoban Village, Tumei Village, and Beiling Village. The baseline survey recruited 1 563 family members from 452 extended pedigrees. The pedigree reconstruction was based on the family information registration and the genealogy booklet. Univariate and bivariate heritability was estimated using variance component models for continuous variables, and susceptibility-threshold model for binary variables. RESULTS: The pedigree reconstruction identified 1 seven-generation pedigree, 2 five-generation pedigrees, 23 four-generation pedigrees, 186 three-generation pedigrees, and 240 two-generation pedigrees. The mean age of the participants was 57.2 years and the males accounted for 39.4%. The prevalence of hypertension, diabetes, dyslipidemia in this population was 49.2%, 10.0%, and 45.2%, respectively. The univariate heritability estimation of resting heart rate, hypertension, and dyslipidemia was 0.263 (95%CI: 0.120－0.407), 0.404 (95%CI: 0.135－0.673), and 0.799 (95%CI: 0.590－1), respectively. The heritability of systolic blood pressure, diastolic blood pressure, fasting glucose, total cholesterol, triglyceride, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol was 0.379, 0.306, 0.393, 0.452, 0.568, 0.852, and 0.387, respectively. In bivariate analysis, there were phenotypic correlations between resting heart rate with hypertension, diabetes, diastolic blood pressure, fasting glucose, and triglyceride. After taking resting heart rate into account, there were strong genetic correlations between resting heart rate with fasting glucose (genetic correlation 0.485, 95%CI: 0.120－1, P<0.05) and diabetes (genetic correlation 0.795, 95%CI: 0.181－0.788, P<0.05). CONCLUSION Resting heart rate was a heritable trait and correlated with several common chronic diseases and related traits. There was strong genetic correlation between resting heart rate with fasting glucose and diabetes, suggesting that they may share common genetic risk factors.

An ideal animal model of azoospermia would be a powerful tool for the evaluation of spermatogonial stem cell (SSC) transplantation. Busulfan has been commonly used to develop such a model, but 30%-87% of mice die when administered an intraperitoneal injection of 40 mg kg^-1. In the present study, hematoxylin and eosin staining, Western blot, immunofluorescence, and quantitative real-time polymerase chain reaction were used to test the effects of busulfan exposure in a mouse model that received two intraperitoneal injections of busulfan at a 3-h interval at different doses (20, 30, and 40 mg kg^-1) on day 36 or a dose of 40 mg kg^-1 at different time points (0, 9, 18, 27, 36, and 63 days). The survival rate of the mice was 100%. When the mice were treated with 40 mg kg^-1 busulfan, dramatic SSC depletion occurred 18 days later and all of the germ cells were cleared by day 36. In addition, the gene expressions of glial cell line-derived neurotrophic factor (GDNF), fibroblast growth factor 2 (FGF2), chemokine (C-X-C Motif) ligand 12 (CXCL12), and colony-stimulating factor 1 (CSF1) were moderately increased by day 36. A 63-day, long-term observation showed the rare restoration of endogenous germ cells in the testes, suggesting that the potential period for SSC transplantation was between day 36 and day 63. Our results demonstrate that the administration of two intraperitoneal injections of busulfan (40 mg kg^-1 in total) at a 3-h interval to mice provided a nonlethal and efficient method for recipient preparation in SSC transplantation and could improve treatments for infertility and the understanding of chemotherapy-induced gonadotoxicity.

Objective: : Covered stenting is an optional strategy for traumatic carotid pseudoaneurysm, especially in malignant conditions of potential rupture, but the long-term outcomes are not clear. Our aim was to determine if covered stenting is an effective option for traumatic carotid pseudoaneurysm with promising long-term outcomes. Methods: : Self-expanding Viabahn and balloon-expandable Willis covered stents were separately implanted for extra- and intracranial traumatic carotid pseudoaneurysm. The covered stent was placed across the distal and proximal pseudoaneurysm leakage under roadmap guidance. Procedural success was defined as technical success (complete exclusion of the pseudoaneurysm and patency of the parent artery) without a primary end point (any stroke or death within 30 days after the procedure). Longterm outcomes were evaluated as ischemic stroke in the territory of the qualifying artery by clinical follow-up through outpatient or telephone consultation and as the exclusion of the pseudoaneurysm and patency of the parent artery by imaging follow-up through angiography. Results: : Five patients with traumatic carotid pseudoaneurysm who underwent covered stenting were enrolled. The procedural success rate was 100%. No ischemic stroke in the territory of the qualifying artery was recorded in any of the five patients during a mean clinical follow-up of 44±16 months. Complete exclusion of the pseudoaneurysm and patency of the parent artery were maintained in all five patients during a mean imaging follow-up of 39±16 months. Conclusion : Satisfactory procedural and long-term outcomes were obtained, suggesting that covered stenting is an effective option for traumatic carotid pseudoaneurysm.

General anesthesia is an unconscious state induced by anesthetics for surgery. The molecular targets and cellular mechanisms of general anesthetics in the mammalian nervous system have been investigated during past decades. In recent years, K channels have been identified as important targets of both volatile and intravenous anesthetics. This review covers achievements that have been made both on the regulatory effect of general anesthetics on the activity of K channels and their underlying mechanisms. Advances in research on the modulation of K channels by general anesthetics are summarized and categorized according to four large K channel families based on their amino-acid sequence homology. In addition, research achievements on the roles of K channels in general anesthesia in vivo, especially with regard to studies using mice with K channel knockout, are particularly emphasized.

Objective To understand the pathogenic distribution and epidemiological trend of hand-foot-and-mouth disease (HFMD),and provide evidence for the prevention and control of HFMD.Methods Children who were diagnosed with HFMD in a hospital between January and December 2015 were investigated,real time fluorescence PCR was used to detect enterovirus universal type EV,enterovirus 71 (EV71),and Coxsackievirus A16 (CoxA16) in specimens from children with HFMD.Positive rates and distribution of various types of EV among children of different months,genders,age groups,and infection types were analyzed.Results A total of 837 throat swab specimens from HFMD children were collected in 2015,380 (45.40％) of which were EV positive specimens.Virus typing showed that 110 (28.95 ％),7 (1.84 ％),6(1.58 ％),and 257(67.63 ％) were positive specimens for EV71,CoxA16,EV71 + CoxA16,and other types of EV.HFMD had a high prevalence since April,reached a peak in May-June,and remained high incidence in July-December.Positive rates of EV in children of different months were statistically different (P＜0.05).The age of onset was mainly in children under 3 years.Positive rates of EV and constitute ratios of different types of EV in children of different age groups were all statistically different (all P＜0.05).The positive rate of EV in severe HFMD cases was higher than common cases (65.34％ vs 27.06％,P＜0.001).The proportion of severe cases in children with EV71 infection and other types of EV infection were 90.00％ and 60.70％ respectively;children with EV71 + CoxA16 double infection were all severe cases.Constitute of EV types in children with different infection types was statistically different(P＜0.001).Conclusion In 2015,EV infection in hospitalized children with HFMD in this hospital was mainly caused by other types of EV (nonEV71 and non-CoxA16),the high prevalence season,high-risk population under 3 years of age,and severe cases should be paid high attention,prevention and treatment should be performed well.

OBJECTIVETo investigate the features of methylation in the promoter region of glucose-6-phosphate dehydrogenase (G6PD) gene and the association between gene promoter methylation and G6PD deficiency.

METHODSFluorescent quantitative PCR was used to measure the mRNA expression of G6PD in 130 children with G6PD deficiency. Sixty-five children without G6PD deficiency served as the control group. The methylation-sensitive high-resolution melting curve analysis and bisulfite PCR sequencing were used to analyze gene promoter methylation in 22 children with G6PD deficiency and low G6PD mRNA expression. The G6PD gene promoter methylation was analyzed in 44 girls with normal G6PD mRNA expression (7 from G6PD deficiency group and 37 from control group).

RESULTSTwenty-two (16.9%) children with G6PD deficiency had relatively low mRNA expression of G6PD; among whom, 16 boys showed no methylation, and 6 girls showed partial methylation. Among the 44 girls with normal G6PD mRNA expression, 40 showed partial methylation, and 4 showed no methylation (1 case in the G6PD group and 3 cases in the control group).

CONCLUSIONSGene promoter methylation is not associated with G6PD deficiency in boys. Girls have partial methylation or no methylation in the G6PD gene, suggesting that the methylation may be related to G6PD deficiency in girls.

HPLC was used to analyze its purity, chemical and spectroscopy methods were used to determine their structures. 12 constituents were isolated and identified as(2R, 19R)methyl 2-acetyloxy-19- hydroxyl-3-oxo-urs-12-en-28-carboxylate(1), pomonic acid (2), 18, 19-seco, 2α, 3α-dihydroxy-19-oxo-urs-11, 13(18)-dien-28-oic acid(3), swinhoeic acid (4), myrianthic acid(5), 2α, 3β, 19α-trihydroxy-24-oxo-urs-12-en-oic acid (6), tormentic acid(7), arjunic acid (8), 1β-hydroxyeuscaphic acid(9), quadranoside Ⅷ (10), alpinoside(11), rubuside B (12). Compounds 1-4, 6, 9, 11-12 were obtained from this plant for the first time. Compounds 2-4, 6, 11-12 were obtained from the genus Rosa for the first time.

OBJECTIVETo analyze the whole microbial structure in a case of rampant caries to provide evidence for its prevention and treatment.

METHODSClinical samples including blood, supragingival plaque, plaque in the caries cavity, saliva, and mucosal swabs were collected with the patient's consent. The blood sample was sent for routine immune test, and the others samples were stained using Gram method and cultured for identifying colonies and 16S rRNA sequencing. DNA was extracted from the samples and tested for the main cariogenic bacterium (Streptococcus mutans) with qPCR, and the whole microbial structure was analyzed using DGGE.

RESULTSThe patient had a high levels of IgE and segmented neutrophils in his blood. Streptococci with extremely long chains were found in the saliva samples under microscope. Culture of the samples revealed the highest bacterial concentration in the saliva. The relative content of hemolytic bacterium was detected in the samples, the highest in the caries cavity; C. albicans was the highest in the dental plaque. In addition, 33 bacterial colonies were identified by VITEK system and 16S rDNA sequence phylogenetic analysis, and among them streptococci and Leptotrichia wade were enriched in the dental plaque sample, Streptococcus mutans, Fusobacterium nucleatum, and Streptococcus tigurinus in the caries cavity, and Lactobacillus in the saliva. S. mutans was significantly abundant in the mucosal swabs, saliva and plaque samples of the caries cavity as shown by qPCR. Compared to samples collected from a healthy individual and another two patients with rampant caries, the samples from this case showed a decreased bacterial diversity and increased bacterial abundance shown by PCR-DGGE profiling, and multiple Leptotrichia sp. were detected by gel sequencing.

CONCLUSIONThe outgrowth of such pathogenic microorganisms as S. mutans and Leptotrichia sp., and dysbiosis of oral microbial community might contribute to the pathogenesis of rampant caries in this case.
