Experience of Medicinal Insects for Gynaecological Diseases / 中医杂志

It is believed that all kinds of gynaecological diseases are mostly related to deficiency and stagnation of qi and blood. Medicinal insects are good at running and scurrying， with the effectiveness of activating blood circulation and dispelling blood stasis， moving qi and relieving pain， searching and dredging collaterals， attacking hardness and dissipating mass， and purging foetus and resolving mass， etc. Appropriate prescriptions can enhance the effectiveness of the formula in eliminating blood stasis and eliminating stagnation. In the treatment of menstrual disorders， chronic pelvic inflammatory disease， uterine cavity disease， incomplete miscarriage， ectopic pregnancy， and other gynaecological diseases， medicinal insects including Quanxie （Scorpio）， Wugong （Scolopendra）， Tubiechong （Eupolyphaga/Steleophaga）， Jiuxiangchong （Coridius chinenses）， Shuizhi （Hirudo）， Mangchong （Tabanus）， Dilong （Pheretima） and other insects for medicinal purposes could be used， and the self-prescribed empirical formulas such as Sanhuang Decoction （三黄汤）， Hongteng Decoction （红藤汤）， Penning Decoction （盆宁方）， Shapei Decoction （杀胚方）， and Gongwaiyun Decoction （宫外孕方） and so on， were all applied medicinal insects and showed effective in clinic.

Polipectomia a frio: um procedimento seguro para remover pequenas lesões colorretais não pediculadas / Cold snare polypectomy: a safe procedure for removing small non-pedunculated colorectal lesions

ABSTRACT Background: Polypectomy is an important treatment option for preventing colorectal cancer. Incomplete polyp resection (IPR) is re­cognized as a risk factor for interval cancer. Objective: The primary objective was to evaluate the complete polyp resection (CPR) rate for cold snare polypectomy (CSP) in small non-pedunculated polyps and, secondarily, specimen retrieval and complication rates. Methods: We prospectively evaluated 479 polyps <10 mm removed by CSP in 276 patients by an inexperienced endoscopist. Results: A total of 476 polyps (99.4%) were resected en bloc. A negative margin (classified as CPR) was observed in 435 polyps (90.8%). An unclear or positive margin (classified as IPR) was observed in 43 cases (9.0%) and 1 case (0.2%), respectively, for an overall IPR rate of 9.2% (44/479). The IPR rate was 12.2% in the first half of cases and 5.9% in the second half (P=0.02). Dividing into tertiles, the IPR rate was 15.0% in the first tertile, 6.9% in the second tertile, and 5.7% in the third tertile (P=0.01). Dividing into quartiles, the IPR rate was 15.8% in the first quartile and 5.9% in the fourth quartile (P=0.03). The IPR rate was 6.3% for type 0-IIa lesions and 14.1% for type 0-Is lesions (P=0.01). For serrated and adenomatous lesions, the IPR rate was 9.2%. Specimen retrieval failed in 3.6% of cases. Immediate bleeding (>30 s) occurred in 1 case (0.2%), treated with argon plasma coagulation. No delayed bleeding or perforation occurred. Conclusion: CSP is a safe technique that provides good results for the resection of small non-pedunculated polyps, with a short learning curve.

RESUMO Contexto: A polipectomia é uma importante opção terapêutica na prevenção do câncer colorretal (CCR). A ressecção incompleta do pólipo (RIP) é reconhecida como fator de risco para o câncer de intervalo. Objetivo: O principal objetivo foi avaliar o índice de ressecção completa da polipectomia a frio (PF) em pequenos pólipos não pediculados e, secundariamente, a recuperação do espécime e índice de complicações. Métodos: Avaliamos prospectivamente 479 pólipos <10 mm removidos por PF em 276 pacientes, por um endoscopista sem experiência com este método. Resultados: Foram ressecados em bloco 476 pólipos (99,4%). Tivemos margem negativa, considerada ressecção completa do pólipo (RCP), em 435 (90,8%) casos. Margem indefinida ou positiva (classificada como RIP) foi observada em 43 (9,0%) casos e em 1 (0,2%) caso, respectivamente, com um índice global de RIP de 9,2% (44/479). O índice de RIP foi de 12,5% na primeira metade dos casos e 5,9% na última metade (P=0,02). Dividindo em tercis, o índice de RIP foi de 15,0% no primeiro terço, 6,9% no segundo terço e 5,7% no terceiro quarto, P=0,01. Dividindo em quartis, o índice de RIP foi de 15,8% no primeiro quarto, enquanto o último quarto foi de 5,9%, P=0,03. O índice de RIP foi de 6,3% para lesões tipo 0-IIa e de 14,1% para lesões tipo 0-Is, P=0,01. O índice de RIP foi de 9,2% para lesões serrilhadas e adenomatosas. Houve falha na recuperação dos espécimes em 3,6% dos casos. Sangramento imediato (>30 s) ocorreu em um caso (0,2%), controlado com plasma de argônio. Sem sangramento tardio e perfuração. Conclusão: PF é uma técnica segura que apresenta bons resultados para a ressecção de pequenas lesões não pediculadas, com uma curta curva aprendizado.

Diagnosis and Treatment Reasoning of Integrated Traditional Chinese and Western Medicine Against Acute Abdomen Based on Knowledge Graph / 中国实验方剂学杂志

ObjectiveIn view of the standardization of clinical diagnosis and treatment of the acute abdomen and the inheritance of diagnosis and treatment experience of prestigious veteran traditional Chinese medicine（TCM） doctors， a diagnosis and treatment reasoning algorithm based on association rule mining under incomplete evidence（AMIE）+ random walk was proposed to provide information services and technical support for primary doctors by recommending personalized diagnosis and treatment plans based on medical records. MethodThe experience of diagnosis and treatment of acute abdomen of prestigious veteran TCM doctors and the text data of clinical diagnosis and treatment guidelines of integrated TCM and western medicine were collected to complete the task of knowledge extraction and construct acute abdomen knowledge graph based on Neo4j. On the basis of ontology-supported rule-based reasoning， the rule reasoning based on similar syndromes was used to expand the syndrome combinations whose Jaccard similarity was greater than the threshold in the syndrome recommendation results. The semantic path coverage algorithm was used to calculate the semantic similarity between the symptom nodes. The symptom nodes were divided into 10 categories， and the symptom nodes in the same category were extended. The random walk algorithm was used to search the symptom nodes connected with the syndrome， and the connection rules between the syndrome and symptom nodes were extended to realize the knowledge reasoning of AMIE+ random walk. ResultThe acute abdomen knowledge graph included 1 320 nodes and 2 464 relationships. According to the link prediction evaluation index of knowledge reasoning， the reasoning results of the three algorithms in the auxiliary diagnosis and treatment of acute abdomen were compared. The AMIE+ random walk algorithm complemented the knowledge graph by extending the similar syndrome connection rules and the syndrome-symptom connection rules. Compared with the knowledge reasoning algorithm based on ontology rules， the area under the curve （AUC） was 15.18% higher and the accuracy was 30.36% higher， which achieved more accurate and effective knowledge inference. ConclusionThis study used knowledge graph technology to visualize the diagnosis and treatment of acute abdomen with TCM and western medicine， assisting primary clinicians in intuitively viewing the diagnosis and treatment process and data relationship. The proposed diagnosis and treatment reasoning algorithm can realize the personalized diagnosis and treatment plan recommendation at the level of "disease-syndrome-diagnosis-treatment-prescription"， which can assist primary doctors in disease diagnosis and treatment and clinical decision-making， contribute to the knowledge sharing and application of diagnosis and treatment experience and clinical guidelines of prestigious veteran TCM doctors， improve the level of primary clinical diagnosis and treatment， and promote the normalization and standardization of the diagnosis and treatment process of acute abdomen with integrated TCM and western medicine.

Diagnosis and treatment of incomplete Kawasaki disease in children / 中国当代儿科杂志

Kawasaki disease (KD) is a febrile disease mainly observed in children aged <5 years, with medium- and small-vessel vasculitis as the main lesion. Although KD has been reported for more than 50 years and great progress has been made in the etiology and pathology of KD in recent years, there is still a lack of specific indicators for the early diagnosis of KD, especially with more difficulties in the diagnosis of incomplete Kawasaki disease (IKD). At present, there are no clear diagnostic criteria for IKD, which leads to the failure of the timely identification and standardized treatment of IKD in clinical practice and even induce the development of coronary artery lesion. This article reviews the concept, epidemiological features, diagnosis, treatment, and follow-up management of IKD, in order to deepen the understanding of IKD among clinical workers and help to improve the clinical diagnosis and treatment of KD in China.

Effect of torso training on unstable surface on lower limb motor function in patients with incomplete spinal cord injury / 浙江大学学报·医学版

OBJECTIVES@#To investigate the effect of torso training on unstable surface on lower limb motor function in patients with incomplete spinal cord injury.@*METHODS@#A total of 80 patients with incomplete spinal cord injury caused by thoracolumbar fracture admitted in Ningbo Yinzhou No.2 Hospital from April 2020 to December 2021 were randomly divided into control group and study group, with 40 cases in each group. In addition to routine training, the control group received torso training on stable surface and the study group received torso training on unstable surface. The gait, lower limb muscle strength, balance function, lower limb function, mobility and nerve function of the two groups were compared.@*RESULTS@#After treatment, the stride length, stride frequency and comfortable walking speed improved in the two groups (all P<0.05), and the improvements in study group were more significant (all P<0.05). The muscle strength of quadriceps femoris, gluteus maximus, hamstring, anterior tibialis and gastrocnemius were improved in the two groups (all P<0.05), and the improvements in study group were more significant (all P<0.05); the total trajectories of static eye opening and static eye closing gravity center movement in the two groups were significantly shorter (all P<0.05), and the improvements in the study group were more significant (all P<0.05). The dynamic stability limit range and the American Spinal Injury Association (ASIA) lower extremity motor score, Berg balance scale, modified Barthel index scale in the two groups were significantly higher (all P<0.05), and these scores in study group were significantly higher than those in the control group (all P<0.05). Both groups showed a significant improvement in ASIA grade (all P<0.05), and the improvement in the study group was significantly better (P<0.05).@*CONCLUSIONS@#Torso training on unstable surface can effectively improve the gait and lower limb muscle strength of patients with incomplete spinal cord injury and improve the lower limb motor function.

Acupuncture combined with auricular point sticking for girls aged 3-8 years with incomplete precocious puberty: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the efficacy and safety of acupuncture combined with auricular point sticking for girls aged 3-8 years with incomplete precocious puberty (IPP).@*METHODS@#Sixty girls with IPP were randomly divided into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 2 cases were eliminated). The girls in the control group were treated with healthy diet and proper exercise for 12 weeks. On the basis of the treatment in the control group, the girls in the observation group were treated with acupuncture combined with auricular point sticking. The acupuncture was applied at Sanyinjiao (SP 6), Guanyuan (CV 4), Guilai (ST 29), etc., the needles were retained for 20 min, acupuncture was given twice a week (once every 3 days). The auricular point sticking was applied at Luanchao (TF2), Neishengzhiqi (TF2), Neifenmi (CO18), Yuanzhong (AT2,3,4i), etc., twice a week. The treatment was given for 12 weeks. Before treatment, after treatment and in follow-up after 12 weeks of treatment completion, the Tanner stage of breast, serum contents of sex hormone (luteinizing hormone [LH], follicle-stimulating hormone [FSH], estradiol [E2]) were observed. The ovarian volume, the number of follicles with diameter>4 mm, and the uterine volume were measured by abdominal color Doppler ultrasound. In addition, the safety of the observation group was evaluated.@*RESULTS@#Compared with before treatment, the Tanner stage of breast in the observation group was improved after treatment and in follow-up (P<0.05); after treatment and in follow-up, the Tanner stage of breast in the observation group was better than that in the control group (P<0.05). Compared with before treatment, the serum levels of LH and E2 in the observation group were increased (P<0.05), and the volume of bilateral ovaries was larger (P<0.05) in follow-up. Compared with before treatment, the serum contents of LH, FSH and E2 in the control group were increased (P<0.05), the volume of bilateral ovaries was larger (P<0.05), and the number of follicles was increased (P<0.05) after treatment and in follow-up. The serum levels of LH, FSH and E2 in the observation group were lower than those in the control group (P<0.05), the volume of bilateral ovaries was smaller than that in the control group (P<0.05), and the number of follicles was lower than that in the control group (P<0.05). Compared with before treatment, the uterine volume in the two groups was larger in follow-up (P<0.05). There was no statistically significant difference between the two groups after treatment and in follow-up (P>0.05). During the treatment, 3 cases in the observation group had slight abdominal pain and subcutaneous blood stasis, without serious adverse reactions.@*CONCLUSION@#Acupuncture combined with auricular point sticking could improve the Tanner stage of breast, reduce the level of sex hormone, slow down the development and maturation of ovary and follicle, and control the degree and speed of sexual development in girls aged 3-8 years with IPP.

Comparison study colonic polypectomy / Монголын Анагаах Ухаан

Introduction@#Colorectal cancer remains one of the critical healthcare challenges nowadays. There are a lot of studies done on colonic polypectomy around the world, and mostly diagnosis with dysplasia change, so we consider to chose to study this topic.@*Aim@#In this study, we aimed to compare the between cold snare polypectomy (CSP) and hot snare polypectomy (HSP) of removing colon polyps. This method helped us to investigate which of the two methods is most prevalent for polypectomy.@*Materials and Method@#The research was carried out using a targeted sampling method from the cases where colonoscopy was performed between 2022 and 2023, based on the Center for Imaging Diagnostics and Pathology of Third General Hospital of Mongolia with a colon polyps less than 5mm in size should be removed using the cold snare method according to the recommendation, and polyps between 5-10 mm should be removed using the hot snare method. After polypectomy, we assessed deep mucosal lesions using the Sydney classification.@*Result@#The average age of the 81 cases included in the study was 57.9 years, and the male-female ratio was 1:1.2.149 cases (75.6%) of slightly elevated type 0-IIa according to the Paris classification, according to the morphological structure revealed by endoscopy, while 79 cases (75.6%) were tubular adenoma according to histological analysis. (38.9%), low grade dysplasia 52 (25.6%) and high grade dysplasia 3 (1.5%) cases are noteworthy. Average polyp was 5-9 mm. Most of polyps removed was left side of colon especially in sigmoid colon. Bleeding rate was higher in hot snare method 11.5%. (1/149, 0.7%, 5/52, 9.6%; P = 0.6). There was no recurrent rate and no perforation in our study. @*Conclusions@#In our study, average size of 5-9 mm were removed and slightly elevated (0-IIa), sessile (0-Is) type of polyps were commonly found in the sigmoid colon. There is a higher risk of bleeding due to mucosal damage in hot snare polypectomy. A combination of hot and cold methods is equally effective for resection of colon pollyps up to 1 cm in size.

Revascularização pulpar, uma nova opção na terapêutica endodôntica: revisão da literatura e caso clínico em paciente adulto / Pulpar revascularization, a new option in endodontc therapy: literature review and case report in adult patient

Introdução: A revascularização pulpar é uma terapêutica que visa regenerar parte do complexo dentino pulpar, proporcionando a continuidade do desenvolvimento radicular, sanando a fragilidade e propensão a fratura que a apicificação apresentava. É um tratamento direcionado a dentes diagnosticados com rizogênese incompleta. Entretanto, a possibilidade de realização da técnica em dentes maduros tem sido alvo de pesquisas e estudo. Objetivo: O objetivo deste estudo, é apresentar através da revisão de literatura e caso clínico, os benefícios dos procedimentos endodônticos regenerativos (REPs), em dentes jovens e maduros, em relação à apicificação. Metodologia: O estudo é uma revisão de literatura, desenvolvida através de pesquisa exploratória e realizada uma abordagem qualitativa. Para a coleta de dados, foi aplicada a técnica de análise documental e revisão bibliográfica consultando PUBMED, Scielo, Google Acadêmico e monografias acadêmicas. O caso clínico foi realizado de acordo com o protocolo atualizado pela AAE em 2016. Discussão: A revascularização pulpar tem mostrado ser um tratamento promissor na endodontia, é preconizada a desinfecção e medicação intracanal, já que não pode haver instrumentação mecânica. Os agentes irrigadores devem ser bactericidas, bacteriostáticos e devem ter baixo teor de toxicidade, já a medicação intracanal deve ter papel inibidor em bactérias gram positivas e gram negativas. Conclusão: A apicificação mesmo com o uso de MTA, que não exige trocas excessivas de medicações, não sana as necessidades que um dente com rizogênese incompleta requer. Sendo assim, a revascularização foi eleita o tratamento de melhor prognóstico para dentes jovens e necrosados. O caso clínico demonstrou qualidade moderada, no tratamento regenerativo em um dente maduro com reabsorção externa, abrindo novas perspectivas para os (REPs)(AU)

Introduction: Pulp revascularization is a therapy that aims to regenerate part of the pulp dentin complex, providing continuity of root development, remedying the fragility and propensity to fracture that apexification presented. It is a treatment aimed at teeth diagnosed with incomplete rhizogenesis. However, the possibility of performing the technique on mature teeth has been the subject of research and study. Objective: The aim of this study is to present, through literature review and clinical case, the benefits of regenerative endodontic procedures (REPs), in young and mature teeth, in relation to apexification. Methodology: The study is a literature review, developed through exploratory research and carried out a qualitative approach. For data collection, the technique of document analysis and bibliographic review was applied, consulting PUBMED, Scielo, Academic Google and academic monographs. The clinical case was performed according to the protocol updated by the SEA in 2016. Discussion: Pulp revascularization has shown to be a promising treatment in endodontics, intracanal disinfection and medication is recommended, as there can be no mechanical instrumentation. Irrigating agents must be bactericidal, bacteriostatic and must have a low level of toxicity, whereas intracanal medication must have an inhibiting role in gram positive and gram negative bacteria. Conclusion: Apexification, even with the use of MTA, which does not require excessive medication changes, does not meet the needs that a tooth with incomplete rhizogenesis requires. Therefore, revascularization was chosen as the treatment with the best prognosis for young and necrotic teeth. The clinical case demonstrated moderate quality in regenerative treatment in a mature tooth with external resorption, opening new perspectives for (REPs)(AU)

Introduction: Kawasaki disease (KD) is a systemic vasculitis of medium vessels, which preferentially affects children under 5 years of age. In its unknown etiology, genetic predisposition, and interaction with viral respiratory agents, including the seasonal coronavirus, are proposed. A marked increase in the incidence of this disease has been reported in the COVID-19 pandemic. Objectives: The objective was to compare the clinical-epidemiological characteristics of KD, before and during the COVID-19 pandemic, at IAHULA, Mérida, Venezuela (2010 - 2022). Material and Methods: A comparative study was designed, of series of clinical cases, a cohort between 01/01/2010 and 03/10/2020; and the other from 03/11/2020 to 04/30/2022, demographic, clinical, echocardiographic and treatment aspects were assessed. The distribution of frequencies, means, standard deviation, Chi-Square or Student's t tests were analyzed. Results: We found a total of forty-nine patients (n=49, 100 %), twenty-three (n=23, 46.9 %) with complete KD predominated during the pandemic (68.8 % vs 63.6 %, p=0.034), they presented a higher proportion of nonexudative bulbar conjunctivitis, leukocytosis and elevated C-reactive protein (CRP), pericardial effusion stood out as a cardiovascular finding in 20 % of cases; all had positive SARS-CoV-2 IgG, as did 2 with antigenic testing. The mean age was 3.2±3.1 years. Children under 5 years of age were the most affected. Seven had other viruses that triggered pre-pandemic EK expression. Conclusions: SARS-CoV-2 could have acted as a trigger for the increase in complete KD in a pandemic; early administration of immunoglobulin, evaluation and respective cardiovascular follow-up are essential.

Complete and incomplete lower motor neuron facial palsy in post-COVID-19 mucormycosis

Purpose: To study facial nerve palsy (FNP) in post?COVID?19?mucormycosis patients and its ocular complications, report different presentations of FNP in such patients, and propose its etiopathogenesis based on presentation and clinico?radiologic localization. Methods: A prospective cohort study was carried out in patients of post?COVID?19?mucormycosis who presented at our tertiary center, over a period of 3 months. Motor and sensory examination of the facial nerve was done to diagnose FNP and localize the lesion clinically. Slit?lamp examination was done for grading corneal involvement. MRI brain, orbit, and paranasal sinuses (PNS) with contrast were studied to find involvement along the facial nerve. It was assessed whether this site of lesion corresponded with clinical localization. Data were analyzed using the percentage of total cases and Fisher抯 test. Results: A total of 300 patients with post?COVID?19 mucormycosis were examined, of which 30 (10%) patients were found to have FNP. All were lower motor neuron (LMN) type and were associated with corneal complications. The most common site clinically was distal to the chorda tympani (66.66%) and radiologically was infratemporal (IT) fossa (63.4%). The clinical localization significantly correlated with the radiological findings (P = 0.012). Twenty percent of patients showed incomplete involvement of facial muscles. Conclusion: FNP was found to be of LMN type. The most common site of insult was IT fossa. There was a good clinico?radiological correspondence of lesions. Isolated lesions were also found along the peripheral nerve course, presenting as incomplete facial palsy. Recognition of FNP in post?COVID?19 mucormycosis, in all its variable forms, is important to manage corneal complications

A 41?year?old man presented to the emergency department complaining of decrease of vision in his left eye. Initial examination was consistent with retrobulbar optic neuritis, and an intravenous drip of methylprednisolone was started. On the third day, the fundus examination revealed the appearance of multiple Purtscher?like cotton?wool spots in the posterior pole and nasally to the optic disc, slight retinal whitening around the fovea, and cherry?red spot. The patient reported flu?like symptoms, and he tested positive at PCR (polymerase chain reaction) test for 2019?nCoV (2019 novel coronavirus) infection. Assuming possible 2019?nCoV?related vascular damage, we prescribed low?molecular?weight heparin. The lesions were regressing at follow?up, and we registered a complete visual recovery

Clinical research of incomplete immune tolerance to donor specific blood group antigen in pediatric ABO incompatible living donor liver transplantation recipients / 中华器官移植杂志

Objective:To explore the potential immune mechanism of pediatric ABOi-LDLT presenting low humoral immune response to donor specific blood group antigen.Methods:From June 2013 to December 2020, clinical data were retrospectively reviewed for 29 patients of long-term surviving pediatric ABOi-LDLT.There were A to O ABOi-LDLT( n=10)and B to O ABOi-LDLT( n=19). Graft types included left lateral lobe( n=26)and left hemi-liver( n=3). The median age of liver transplantation was 10 months, the median weight 8.0 kg and the median follow-up time 41.9 months.The titers of donor specific blood group antibodies and non-donor specific blood group antibodies(IgG, IgM)were continuously monitored before transplantation and at 1, 3, 6, 12, 24, 36 months post-transplantation.Protocol or event-based liver biopsy was performed to determine whether or not there was antibody-mediated rejection. Results:The titer of donor specific blood group antibody in recipients was significantly lower than that of non-donor specific blood group antibody( P<0.001). Among 18 protocol liver pathological biopsies, two cases were C4d positive for vascular endothelium.Five abnormal event-based liver biopsies were completed and one was C4d positive in bile duct endothelium.No pathological sign of typical blood group antibody mediated antigen-antibody complex mediated cascade immune reaction was detected in liver pathological biopsy.Typical pathological signs of blood group antibody mediated rejection were absent in protocol liver biopsy. Conclusions:Donor specific blood group antibody is expressed at a low level in pediatric ABOi-LDLT recipients.It presents as incomplete immune tolerance to donor specific blood group antigen.

Clinical application of the new classification criteria in children with Miller Fisher syndrome and clinical characteristics analysis of different types of Miller Fisher syndrome / 中华实用儿科临床杂志

Objective:To investigate the clinical application of the new classification criteria in children with Miller Fisher syndrome (MFS), and to analyze clinical characteristics of different types of MFS.Methods:Clinical data of MFS patients hospitalized in the Department of Neurology, Beijing Children′s Hospital, Capital Medical University from January 2015 to December 2019 were collected and analyzed retrospectively, including demographic characteristics, clinical symptoms, neurological examination findings, laboratory examination data, diagnosis and treatment, and prognosis.The counting data was described by percentage, and the measurement data was described by median.Results:A total of 23 patients were included in the research, including 14 males and 9 females, with a median age of 4 years and 8 months.There were 3 cases of pure MFS; 5 cases of incomplete MFS, including 1 case of acute ptosis and 4 cases of acute ataxia neuropathy; 15 cases of overlapping syndrome, including 13 cases of MFS/Guillain Barre syndrome (GBS), 1 case of MFS/pharyngocervical brachial variant GBS(PCB GBS)and 1 case of MFS/GBS/Bickertaff brainstem encephalitis (BBE). In addition to Ⅲ, Ⅳ and Ⅵ cranial nerve palsy, 11 cases had the involvement of other cra-nial nerves, including 2 cases in pure MFS, 8 cases in MFS/GBS and 1 case in MFS/GBS/BBE.Autonomic nervous dysfunction occurred in 6 cases.Respiratory muscle paralysis occurred in 6 cases, including 5 cases in MFS/GBS and 1 case in MFS/GBS/BBE.Graded by the Hughes scoring system (HG score), 3 cases with pure MFS were graded 4 points; 1 case with acute ptosis was graded 0; 3 cases with acute ataxia neuropathy were graded 2 points, and the other one was graded 3 points; 1 case with MFS/PCB GBS was graded 3 points; 10 cases with MFS/GBS were graded 4 points, 1 case was graded 3 points, and the other 2 cases were graded 2 points; 1 case with MFS/GBS/BBE was graded 4 points.Twenty-two patients were treated with intravenous immunoglobulin.The HG of all patients at discharge decreased at varying degree, which was graded 0 at 6 months of follow-up.Conclusions:The clinical application of the new diagnostic classification method is helpful to the accurate diagnosis of different types of MFS.More than half of MFS cases will develop into the overlapping syndrome.The overlapping of MFS and GBS or BBE is prone to the involvement of cranial nerves except for the external ophthalmic muscles, autonomic nerve dysfunction and respiratory muscle paralysis.The disease course of MFS varies, and its diagnosis should be comprehensively made.All cases of MFS in this study have a satisfactory prognosis.

Incomplete concerted evolution of nrDNA ITS in Lycium / 药学学报

In this study, nrDNA ITS sequences of Lycium cultivars were sequenced and used to test the existence of incomplete concerted evolution and pseudogenes. Together with 44 ITS sequences retrieved from GenBank, the pattern of base substitutions, GC content, 5.8S conserved motifs, the minimum free energy of secondary structures, nucleotide diversity and phylogenetic relationship of the samples were analyzed. While 83 of the 144 sequences were identified as pseudogenes, the results suggested a high degree of polymorphism and putative pseudogenes in Lycium, suggesting an incomplete concerted evolution of the ITS region. ITS polymorphism and pseudogene of Lycium were systematically tested for the first time. This research provides a references for ITS sequence to be used in the study of Lycium germplasm resources and DNA barcode identification.

Clinical features and CACNA1A gene mutation in a family with episodic ataxia type 2 / 中南大学学报(医学版)

Episodic ataxia (EA) is a group of disorders characterized by recurrent spells of vertigo, truncal ataxia, and dysarthria. Episodic ataxia type 2 (EA2), the most common subtype of EA, is an autosomal dominant disease caused by mutation of the CACNA1A gene. EA2 has been rarely reported in the Chinese population. Here we present an EA2 family admitted to Xiangya Hospital in October 2018. The proband was a 22-year-old male who complained of recurrent spells of vertigo, slurred speech, and incoordination for 4 years. Brain magnetic resonance imaging (MRI) showed cerebellar atrophy. He had neuropsychological development disorder in childhood, and cognitive assessment in adulthood showed cognitive impairment. The proband's mother and grandmother had a similar history. Peripheral blood samples from the proband and family members were collected, and genomic DNA was isolated. Whole exome sequencing of the proband detected a heterozygous frameshift mutation c.2042_2043del (p.Q681Rfs*100) of CACNA1A gene. This mutation was verified in the proband and 2 family members using Sanger sequencing. One family member carrying this mutation was free of symptoms and signs, suggesting an incomplete penetrance of the mutation. We reported a variant c.2042_2043del of CACNA1A gene as the pathogenic mutation in a Chinese EA2 family for the first time. This case enriched the clinical spectrum of CACNA1A related EA2, and contributed to the understanding of clinical and genetic characteristics of EA2 to reduce misdiagnosis.

How to use analysis of variance correctly——an analysis of variance for the univariate quantitative data collected from the balanced incomplete block design / 四川精神卫生

The purpose of this paper was to introduce the model， calculation formulas and the SAS implementation of the analysis of variance for the quantitative data with balanced incomplete block design. In the calculation， two test statistics were involved， namely FA and FB. Among them， the subscript "A" represented the experimental factor， and the subscript "B" represented the block factor B （i.e.， the important non-experimental factor）. In general， it was assumed that there was no or negligible interaction between the two factors in a balanced incomplete block design， so there was no need to evaluate whether the interaction term was statistically significant. Therefore， it was not necessary to do repeated experiments under each combination of two factors. With the help of SAS software， this paper conducted the analysis of variance for the quantitative data with balanced incomplete block design on two examples， and presented the calculation results and made the statistical and professional conclusions.

Study on the influence of residents′ psychological contracts on their behavioral intentions from the perspective of incomplete contracts / 中华医院管理杂志

Objective:To analyze the psychological contract satisfaction of contracted residents and its impact on their behavioral intentions under the guidance of incomplete contract theory, for reference in improving the effectiveness of contracted family doctor services.Methods:1 100 contracted residents from nine townships/streets in Shandong province were selected as subjects according to stratified random sampling from September 2019 to June 2020, and a questionnaire survey on the level of satisfaction of contracted residents′ psychological contracts(24 items) and assessment of behavior intentions(9 items) was conducted, and the model of the effect of contracted residents′ psychological contracts on behavior intentions was established and analyzed. The correlation was validated by Pearson test and the structural equation method was used for verifying the model.Results:998 valid questionnaires were recovered. The psychological contract satisfaction score of the contracted residents was 3.45±0.56 and the behavioral intention was 2.81±0.29. Both transactional and relational psychological contracts were correlated with all dimensions of behavioral intention( P<0.01). Concerning the impacts of residents′ psychological contracts on behavioral intentions, the effect coefficients of transactional psychological contracts on loyalty intention, voice intention, exit intention and neglect intention were 0.33, 0.24, -0.25 and -0.49 respectively, with an indirect effect on neglect intention; the effect coefficients of relational psychological contracts on loyalty intention, voice intention, exit intention and neglect intention were 0.26, 0.10, -0.14 and -0.50 respectively, with an indirect effect on advice intention and neglect intention. Conclusions:Residents′ psychological contract has yet not been effectively satisfied. Satisfying and improving the residents′ psychological contract can directly enhance their loyalty intention and reduce their exit intention, indirectly influencing the voice and neglect intentions. In order to enhance the effectiveness of family doctor contracted services and improve the healthcare experience of contracted residents, it is suggested that the relevant departments should actively take the following measures, including carrying out a survey on the psychological contract of contracted residents, building a provincial-city-county-township collaborative linkage platform, and so on.

A case of ADULT syndrome without finger/toe deformities caused by a TP63 mutation / 中华皮肤科杂志

Objective:To detect causative gene mutations in 1 patient with ADULT syndrome mainly presenting with ectodermal dysplasia.Methods:Clinical data were collected from a proband with ADULT syndrome, and genomic DNA was extracted from peripheral blood samples obtained from the proband and his parents. Exome sequencing was performed in the proband by using targeted panels for hereditary skin diseases to determine mutation sites, and then the candidate mutation sites were verified by Sanger sequencing in the family members.Results:The 22-year-old male patient presented with sparse and thin hair, scattered facial freckles, missing permanent teeth, cloudy corneas, palmoplantar erythema and keratosis, nail/toenail dystrophy, and nipple dysplasia. Genetic testing of the peripheral blood genomic DNA of the proband revealed a heterozygous mutation (c.1040G>T) in exon 8 of the TP63 gene, resulting in an amino acid change at position 347 (p.C347F) . The mutation was not detected in his father or mother with normal phenotypes, suggesting the cosegregation of the gene mutation with the disease phenotype in the family.Conclusion:The de novo heterozygous missense mutation in the TP63 gene may be the causative mutation in the proband, and combined with clinical manifestations, the proband was diagnosed with ADULT syndrome without finger/toe deformities.
