ABSTRACT

Termites are known as social insects worldwide. Presently in China 473 species, 44 genera and 4 families of termites have been reported. Of them, 111 Reticulitermes species are widely spread in different zones of China. The dispersion flight season of these Chinese Reticulitermes species are usually started from February to June, but in some regions different species are distributed, sharing their boundaries and having overlapping flight seasons. These reasons become important sources of hybridization between two different heterospecific populations of termites. It was confirmed that the fertilized eggs and unfertilized eggs of some Reticulitermes termites have the capacity of cleavage. While the unfertilized eggs of R. aculabialis, R. chinensis and R. labralis cleaved normally and the only R. aculabialis unfertilized eggs develop in embryos. While, the R. flaviceps and R. chinensis were observed with their abnormal embryonic development, and not hatching of eggs parthenogenetically. They were reported more threatening to Chinese resources as they propagate with parthenogenesis, hybridization and sexual reproduction. Eggshell and macrophiles of eggs play important roles in species identification and control. Although, they are severe pests and cause a wide range of damages to wooden structures and products in homes, buildings, building materials, trees, crops, and forests in China's Mainland.


Os cupins são conhecidos como insetos sociais em todo o mundo. Atualmente na China foram relatadas 473 espécies, 44 gêneros e 4 famílias de cupins. Destas, 111 espécies de Reticulitermes estão amplamente distribuídas em diferentes zonas da China. A temporada de voo de dispersão dessas espécies chinesas de Reticulitermes geralmente começa de fevereiro a junho, mas em algumas regiões diferentes espécies são distribuídas, compartilhando seus limites e tendo temporadas de voo sobrepostas. Essas razões tornam-se importantes fontes de hibridização entre duas populações heteroespecíficas de cupins. Foi confirmado que os ovos fertilizados e não fertilizados de alguns cupins Reticulitermes possuem capacidade de clivagem. Já os ovos não fertilizados de R. aculabialis, R. chinensis e R. labralis clivaram normalmente, e os únicos ovos não fertilizados de R. aculabialis se desenvolvem em embriões. R. flaviceps e R. chinensis foram observados com desenvolvimento embrionário anormal, e não eclosão de ovos por partenogênese. Eles foram relatados como mais ameaçadores para os recursos chineses à medida que se propagam com partenogênese, hibridização e reprodução sexual. Casca de ovo e macrófilos de ovos desempenham papéis importantes na identificação e controle de espécies, embora sejam pragas graves e causem uma ampla gama de danos a estruturas e produtos de madeira em residências, edifícios, materiais de construção, árvores, plantações e florestas na China continental.

ABSTRACT

Liupan Mountains are an important region in China in the context of forest cover and vegetation due to huge afforestation and plantation practices, which brought changes in soil physio-chemical properties, soil stocks, and soil stoichiometries are rarely been understood. The study aims to explore the distribution of soil nutrients at 1-m soil depth in the plantation forest region. The soil samples at five depth increments (0-20, 20-40, 40-60, 60-80, and 80-100 cm) were collected and analyzed for different soil physio-chemical characteristics. The results showed a significant variation in soil bulk density (BD), soil porosity, pH, cation exchange capacity (CEC), and electric conductivity (EC) values. More soil BD (1.41 g cm-3) and pH (6.97) were noticed in the deep soil layer (80-100 cm), while the highest values of porosity (60.6%), EC (0.09 mS cm-1), and CEC (32.9 c mol kg-1) were reflected in the uppermost soil layer (0-20 cm). Similarly, the highest contents of soil organic carbon (SOC), total phosphorus (TP), available phosphorus (AP), total nitrogen (TN), and available potassium (AK) were calculated in the surface soil layer (0-20 cm). With increasing soil depth increment a decreasing trend in the SOC and other nutrient concentration were found, whereas the soil total potassium (TK) produced a negative correlation with soil layer depth. The entire results produced the distribution of SOCs and TNs (stocks) at various soil depths in forestland patterns were 0→20cm > 20→40cm > 40→60cm ≥ 60→80cm ≥ 80→100 cm. Furthermore, the stoichiometric ratios of C, N, and P, the C/P, and N/P ratios showed maximum values (66.49 and 5.46) in 0-20 cm and lowest values (23.78 and 1.91) in 80-100 cm soil layer depth. Though the C/N ratio was statistically similar across the whole soil profile (0-100 cm). These results highlighted that the soil depth increments might largely be attributed to fluctuations in soil physio-chemical properties, soil stocks, and soil stoichiometries. Further study is needed to draw more conclusions on nutrient dynamics, soil stocks, and soil stoichiometry in these forests.


As montanhas de Liupan são uma região importante na China no contexto de cobertura florestal e vegetação devido às enormes práticas de florestamento e plantação, que trouxeram mudanças nas propriedades físico-químicas do solo, e estoques e estequiometrias do solo raramente são compreendidos. O estudo visa explorar a distribuição de nutrientes do solo a 1 m de profundidade do solo na região da floresta plantada. As amostras de solo em cinco incrementos de profundidade (0-20, 20-40, 40-60, 60-80 e 80-100 cm) foram coletadas e analisadas para diferentes características físico-químicas do solo. Os resultados mostraram uma variação significativa nos valores de densidade do solo (BD), porosidade do solo, pH, capacidade de troca catiônica (CEC) e condutividade elétrica (CE). Mais DB do solo (1,41 g cm-3) e pH (6,97) do solo foram observados na camada profunda do solo (80-100 cm), enquanto os maiores valores de porosidade (60,6%), CE (0,09 mS cm-1) e CEC (32,9 c mol kg-1) foram refletidos na camada superior do solo (0-20 cm). Da mesma forma, os maiores teores de carbono orgânico do solo (SOC), fósforo total (TP), fósforo disponível (AP), nitrogênio total (TN) e potássio disponível (AK) foram calculados na camada superficial do solo (0-20 cm). Com o aumento do incremento da profundidade do solo, uma tendência decrescente no SOC e na concentração de outros nutrientes foi encontrada, enquanto o potássio total do solo (TK) produziu uma correlação negativa com a profundidade da camada do solo. Todos os resultados produziram a distribuição de SOCs e TNs (estoques) em várias profundidades de solo em padrões de floresta 0 → 20cm> 20 → 40cm> 40 → 60cm ≥ 60 → 80cm ≥ 80 → 100 cm. Além disso, as relações estequiométricas de C, N e P, as relações C / P e N / P, apresentaram valores máximos (66,49 e 5,46) em 0-20 cm, e valores mais baixos (23,78 e 1,91) em solo de 80-100 cm profundidade da camada. Embora a relação C / N fosse estatisticamente semelhante em todo o perfil do solo (0-100 cm). Esses resultados destacaram que os incrementos de profundidade do solo podem ser amplamente atribuídos a flutuações nas propriedades físico-químicas do solo, estoques e estequiometrias do solo. Mais estudos são necessários para tirar conclusões adicionais sobre a dinâmica dos nutrientes, estoques de solo e estequiometria do solo nessas florestas.

ABSTRACT

Abstract The COVID-19 is a contagious viral disease, was first emerged in Wuhan, China in December 2019 and became the whole world on alert. The mortality rate in top most countries in Asia with special reference to Pakistan has been focused. Since February 26 to September 2020 the total confirmed cases and mortality rate was measured through Wikipedia and the notable journals. Iran is the only country having highest number of deaths (5.73%) followed by Indonesia (3.77%) while Saudi Arabia shows the lowest number of deaths as 1.39%. In Pakistan the first case was confirmed in 26th February, 2020. The nCov-19 has closely related to severe acute respiratory syndrome (SARS) hence SARS COV-2 was named. This virus is responsible for more than 33.9 million deaths in over all the world as of 20th September, 2020. The number of new cases is increasing time to time. Sindh province of Pakistan has reported the highest number of cases till September, 20, 2020 as compared to other parts of the country and has the highest number of death followed by Khyber Pakhtunkhwa. Because of the person to person contact the disease is spreading rapidly. The individuals who has already infected with other diseases like cancer or diabetic etc. are vulnerable. The nCOV-19 is the most contagious due to its mode of transmission. There is still no vaccine is available for the treatment of disease caused by nCoV-2019. It is therefore the only option to control this pandemic is to adopt effective preventive measures.


Resumo A covid-19 é uma doença viral contagiosa, que surgiu pela primeira vez em Wuhan, China, em dezembro de 2019, e deixou o mundo todo em alerta. A taxa de mortalidade na maioria dos principais países da Ásia, com referência especial ao Paquistão, foi enfocada. De 26 de fevereiro a setembro de 2020, o total de casos confirmados e a taxa de mortalidade foram medidos por meio da Wikipedia e de periódicos notáveis. O Irã é o único país com maior número de mortes (5,73%), seguido pela Indonésia (3,77%), enquanto a Arábia Saudita mostra o menor número de mortes, 1,39%. No Paquistão, o primeiro caso foi confirmado em 26 de fevereiro de 2020. O nCov-19 está intimamente relacionado à síndrome respiratória aguda grave (SARS), daí o nome SARS COV-2. Esse vírus é responsável por mais de 33,9 milhões de mortes em todo o mundo em 20 de setembro de 2020. O número de novos casos está aumentando de tempos em tempos. A província de Sindh, no Paquistão, registrou o maior número de casos até 20 de setembro de 2020, em comparação com outras partes do país, e tem o maior número de mortes, seguida por Khyber Pakhtunkhwa. Por causa do contato pessoa a pessoa, a doença está se espalhando rapidamente. Indivíduos que já foram diagnosticados com outras doenças, como câncer ou diabetes, etc. são mais vulneráveis. O nCOV-19 é o mais contagioso devido ao seu modo de transmissão. Ainda não há vacina disponível para o tratamento da doença causada pelo nCoV-2019. Portanto, a única opção para controlar essa pandemia é a adoção de medidas preventivas eficazes.

ABSTRACT

Abstract The protozoans include many intracellular human pathogens. Accurate detection of these pathogens is necessary to treat the diseases. In clinical epidemiology, molecular identification of protozoan is considered a more reliable and rapid method for identification than microscopy. Among these protozoans, Cryptosporidium considered being one of the important water-borne zoonotic pathogens and a major cause of a diarrheal disease named cryptosporidiosis in humans, domestic animals, and wild animals. This study was aimed to identify Cryptosporidium in zoo felids (N= 56) belonging to different zoo of China, but accidentlly Colpodella was encountered in the zoo felids sample and phylogenetic data confirmed this unexpected amplification from fecal samples using two-step nested-PCR. Phylogenetic analysis revealed the fact about the specific primers used previously by many researchers and cross-genera amplification. We came to know that genetically sequenced amplicon gives more accurate identification of species. This study suggests more investigation on Colpodella which has been neglected previously but gains the attention of researchers after identified from humans and animals and has been known to correlate with neurological symptoms in patients.


Resumo Os protozoários incluem muitos patógenos humanos intracelulares. A detecção acurada desses patógenos é necessária para tratar as doenças. Na epidemiologia clínica, a identificação molecular de protozoários é considerada o método de identificação mais confiável e rápido do que a microscopia. Entre esses protozoários, o Cryptosporidium é considerado um dos importantes patógenos zoonóticos transmitidos pela água e uma das principais causas de uma doença diarreica denominada criptosporidiose em humanos, animais domésticos e selvagens. Este estudo teve como objetivo identificar Cryptosporidium em zoofelídeos (N = 56) pertencentes a diferentes zoológicos da China, mas acidentalmente Colpodella foi encontrada na amostra de zoofelídeos e os dados filogenéticos confirmaram essa amplificação inesperada de amostras fecais usando nested-PCR em duas etapas. A análise filogenética revelou o fato sobre os primers específicos usados ​​anteriormente por muitos pesquisadores e a amplificação entre gêneros. Ficamos sabendo que o amplicon sequenciado geneticamente fornece uma identificação mais acurada das espécies. Este estudo sugere mais investigação sobre Colpodella, que foi negligenciada anteriormente, mas ganha a atenção dos pesquisadores depois de identificada em humanos e animais e é conhecida por se correlacionar com sintomas neurológicos em pacientes.

ABSTRACT

El siguiente trabajo presenta la historia de una paciente de 19 años oriunda de China, que cursó una internación en una sala de psiquiatría de un hospital general por un cuadro de características depresivas. El caso es notable por el polimorfismo en la sintomatología clínica que presentó. El objetivo es analizar, a partir de él, la necesidad de un enfoque interdisciplinario que trate a la cultura como una variable significativa en la construcción de una enfermedad, entendiendo que los modelos fisiopatológicos resultan necesarios pero no suficientes para comprender de qué modo se constituye. Para dicho fin se hará un breve recorrido por los estudios efectuados en la década del 80 en China por el psiquiatra y antropólogo Arthur Kleiman y se desarrollará la perspectiva de la psicoanalista Helena Lunazzi, quien en su libro Alexitimia desarrolla cómo la cultura influye en la expresión verbal de las emociones. (AU)


The following work presents the history of a 19-year-old patient from China who was hospitalized in a psychiatric ward of a general hospital due to a depressive illness, being the case remarkable for the polymorphism in the clinical symptoms that she presented. The objective is to analyze the need for an interdisciplinary approach that treats culture as a significant variable in the construction of a disease, understanding that pathophysiological models are necessary but not sufficient to comprehend how they are constituted. For this purpose, a brief review will be made of the studies carried out in the 1980s in China by the psychiatrist and anthropologist Arthur Kleiman and the perspective of the psychoanalyst Lunazzi Helena, who in her book "Alexithymia" develops how culture influences the verbal expression of emotions.

ABSTRACT

SUMMARY OBJECTIVE: This study aimed at the oral health problems of elderly patients with diabetes. A training course of integrated traditional Chinese and Western medicine was constructed, helping patients improve their oral health quality of life. METHODS: A randomized controlled prospective experimental study was conducted. A total of 190 elderly patients were divided randomly into an observation group and a control group with 95 cases in each. The control group received regular health education, while the observation group was based on the control group to implement the integrated experiential learning of traditional Chinese and Western medicine in small groups. The oral health knowledge, attitude, behavior, and blood glucose control status along with the oral health quality of life of the two groups were compared before the intervention and at 3-month postintervention. RESULTS: Three months after the intervention, the fasting blood glucose control and the 2-h postprandial blood glucose/glycosylated hemoglobin levels in the observation group were significantly better than in the control group, and the difference was statistically significant (p<0.05). The oral health quality of life in the observation group was significantly better than in the control group, and the difference was statistically significant (p<0.05). CONCLUSION: The small-group experiential learning model of integrated Chinese and Western medicine can promote the transformation of knowledge-beliefs-behaviors in elderly patients with diabetes, which is conducive to controlling blood sugar levels and improving the quality of oral health.

ABSTRACT

Trust in automation plays a leading role in human-automation interaction. As there lack of scales measuring trust in automation in China, the purpose of this study was to adapt the trust between People and Automation Scale (TPAS) into Chinese and to demonstrate its psychometric properties among Chinese adults. A total of 310 Chinese adults were randomly selected as sample 1, and 508 Chinese adults as sample 2. Results of the item analysis revealed that each item had a good quality, and the exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) suggested that the two-factor model with 12 items was the best fitting model. In addition, the TPAS was positively correlated with Interpersonal Trust Scale (ITS), proving good evidence based on relations to other variables to support the TPAS. In sum, the study suggested that the Chinese version of the TPAS could be used as an effective tool to assess trust in automation in the Chinese context.

ABSTRACT

OBJECTIVE@#To analyze the effects of ozone (O3) concentrations measured with different approaches across different seasons on the total number of childhood asthma-related clinical visits, as well as the differentiation of such effects across different groups of patients.@*METHODS@#The outpatient data of three grade A tertiary hospitals in Lanzhou City spanning from 1 January 2014 to 31 December 2017, as well as air pollution and meteorological data during the same period were collected. Considering the nonlinear relationship between O3 concentrations and the total number of childhood asthma-related clinical visits and meteorological factors, a generalized additive temporal sequence model was employed to analyze the short-term association between changes in O3 concentrations and the total number of childhood asthma-related clinical visits. Taking into account of the variations in O3 concentrations within 1 day, this study adopted different measurement approaches to address the three types of O3 exposures, namely, the maximum 1 h daily concentration (O3max1h), the maximum 8 h daily concentration (O38h) and the mean 24 h daily concentration (O324h) as the short term exposure indicators to O3, followed by a model-based analysis.@*RESULTS@#The increase in short-term exposure levels to O3 in summer had a significant effect on the increase in the total number of childhood asthma-related clinical visits. With lag0 for the current day, every 10 μg/m3 increase in atmospheric concentration of O3max1h was associated with an increase in the total number of childhood asthma-related clinical visits by 3.351% (95%CI: 1.231%-5.516%); for every 10 μg/m3 increase in O38h concentration, the total number of childhood asthma-related clinical visits increased by 3.320% (95%CI: 0.197%-3.829%); for every 10 μg/m3increase in O324h concentration, the total number of childhood asthma-related clinical visits in summer increased by 6.600% (95%CI: 0.914%-12.607%); moreover, an increase in exposure to O3max1h also led to a significant rise in the total number of childhood asthma-related clinical visits among the males.@*CONCLUSION@#The increase in short-term exposure levels to O3 in summer in Lanzhou City has a significant effect on the increase in the total number of childhood asthma-related clinical visits; O3max1h is more closely correlated with the increase in the total number of childhood asthma-related clinical visits.

ABSTRACT

OBJECTIVE@#To evaluate the accuracy of trephine bur drilling at different depths guided by dynamic navigation system in 3D printing in vitro model.@*METHODS@#A model at the depth of 5 mm, 10 mm, and 15 mm from the outer surface of which hemispherical cavities was reserved and the 3D printing technology was used to make the standardized model with Veroclear resin. The cone beam CT (CBCT) was taken and the data were imported into the dynamic navigation software (DCARER, China) to establish navigation path programming. Under the guidance of dynamic navigation, a trephine bur with a diameter of 4.5 mm was used to complete the access operation. At each depth, 10 approaches were completed. The postoperative model CBCT was taken. The approach trajectory under navigation was reconstructed and compared with the designed path. The two-dimensional distance deviation, depth deviation, three-dimensional distance deviation, and angle deviation between the actually prepared path and the designed path were calculated.@*RESULTS@#At the depth of 5 mm, the two-dimensional distance deviation between the end position of the prepared path and the designed path was (0.37±0.06) mm, the depth deviation was (0.06±0.05) mm, the three-dimensional distance deviation was (0.38±0.07) mm, and the angle deviation was 2.46°±0.54°; At the depth of 10 mm, the four deviations between the end position of prepared path and the designed path were (0.44±0.05) mm, (0.16±0.06) mm, (0.47±0.05) mm, and 2.45°±1.21°, respectively; At the depth of 15 mm, the four deviations were (0.52±0.14) mm, (0.16±0.07) mm, (0.55±0.15) mm, and 3.25°±1.22°, respectively. With the increase of entry depth, the three-dimensional and depth accuracy of dynamic navigation system decreased (P < 0.01), and the positioning angle deviation had no relation with the entry depth (P>0.01).@*CONCLUSION@#Dynamic navigation technology can achieve high positioning accuracy in the depth range of 15 mm, but its deviation increases with the increase of entry depth.

ABSTRACT

In recent years, with the wide application of immune score and liquid biopsy to guide the accurate diagnosis and precise treatment of colorectal cancer, colorectal surgery develops more rationally and scientifically. The strategy of organ function protection in colorectal surgery gradually attracts more and more attention. The continuous development of comprehensive treatments, such as targeted therapy and immunotherapy, provides more choices for colorectal cancer patients. Several significant progress in surgical strategies for benign colorectal diseases challenges the traditional concepts as well. The advances in medical science and the innovation of concepts and ideas set high new standards for the development of colorectal surgery in China. Efforts are required to improve the standardization of diagnosis and treatment of colorectal disease. There is still a long way to go to explore patient-centered new technologies, new concepts and new fields of accurate diagnosis and precise treatment in colorectal surgery.

ABSTRACT

In the last decade, the development of clinical practice guidelines in China has grown rapidly. However, with regards to the guidelines that have been established in the past, few were of high quality and in line with international standards. The main reason for this was that many clinical experts were not familiar with the procedures and rules of clinical guidelines before established, which lowered the quality seriously. Clinical practice guidelines are based on a clinical problem that is distilled into populations, interventions, comparison and outcome (PICO). After comprehensive systematic review, recommendations are made through evidence grading and strength of recommendation system. In addition, other issues should be noted such as pros and cons of the recommendation for specific population, preferences and values of the population, cost-effectiveness, and the health care system. A high-quality guideline requires multidimensional thinking (from clinicians, patients and policy makers), the implementation of a standard procedure (to ensure guidelines scientifically sound, honest and transparent), as well as the collaboration of multiple organizations (including experts, methodologists and policy makers).

ABSTRACT

Objective: To summarize the clinical experience of expanded internal mammary artery perforator (IMAP) flap combined with vascular supercharge in reconstruction of faciocervical scar. Methods: The retrospective observational study was conducted. From September 2012 to May 2021, 23 patients with postburn or posttraumatic faciocervical scars who met the inclusion criteria were admitted to Shanghai Ninth People's Hospital of Shanghai Jiao Tong University School of Medicine, including 18 males and 5 females, aged from 11 to 58 years, all of whom were reconstructed with expanded IMAP flaps. At the first stage, one or two skin and soft tissue expander (s) with appropriate rated capacity were implanted in the anterior chest area according to the location and size of the scars. The IMAP, thoracic branch of supraclavicular artery, and lateral thoracic artery were preserved during the operation. The skin and soft tissue expanders were inflated with normal saline after the operation. The flaps were transferred during the second stage. The dominant IMAP was determined preoperatively using color Doppler ultrasound (CDU) blood flow detector. The faciocervical scars were removed, forming wounds with areas of 9 cm×7 cm-28 cm×12 cm, and the perforators of superficial temporal artery and vein or facial artery and vein were preserved during the operation. The flaps were designed according to the area and size of the wounds after scar resection with the dominant IMAP as the pedicle. Single-pedicle IMAP flaps were used to repair small and medium-sized wounds. For larger defects, the blood perfusion areas of vessels in the anterior chest were evaluated by indocyanine green angiography (ICGA). In situations where the IMAP was insufficient to nourish the entire flap, double-pedicle flaps were designed by using the thoracic branch of supraclavicular artery or lateral thoracic artery for supercharging. Pedicled or free flap transfer was selected according to the distance between the donor areas and recipient areas. After transplantation of flaps, ICGA was conducted again to evaluate blood perfusion of the flaps. The donor sites of flaps were all closed by suturing directly. Statistics were recorded, including the number, rated capacity, normal saline injection volume, and expansion period of skin and soft tissue expanders, the location of the dominant IMAP, the total number of the flaps used, the number of flaps with different types of vascular pedicles, the flap area, the flap survival after the second stage surgery, the occurrence of common complications in the donor and recipient areas, and the condition of follow-up. Results: Totally 25 skin and soft tissue expanders were used in this group of patients, with rated capacity of 200-500 mL, normal saline injection volume of 855-2 055 mL, and expansion period of 4-16 months. The dominant IMAP was detected in the second intercostal space (20 sides) or the third intercostal space (5 sides) before surgery. A total of 25 expanded flaps were excised, including 2 pedicled IMAP flaps, 11 free IMAP flaps, 4 pedicled thoracic branch of supraclavicular artery+free IMAP flaps, and 8 free IMAP+lateral thoracic artery flaps, with flap areas of 10 cm×8 cm-30 cm×14 cm. After the second stage surgery, tip necrosis of flaps in three patients occurred, which healed after routine dressing changes; one patient developed arterial embolism and local torsion on the vascular pedicle at the anastomosis of IMAP and facial artery, and the blood supply recovered after thrombectomy and vascular re-anastomosis. Fourteen patients underwent flap thinning surgery in 1 month to 6 months after the second stage surgery. The follow-up for 4 months to 9 years showed that all patients had improved appearances of flaps and functions of face and neck and linear scar in the donor sites of flaps, and one female patient had obvious nipple displacement and bilateral breast asymmetry. Conclusions: The expanded IMAP flap is matched in color and texture with that of the face and neck, and its incision causes little damage to the chest donor sites. When combined with vascular supercharge, a double-pedicle flap can be designed flexibly to further enhance the blood supply and expand the flap incision area, which is a good choice for reconstruction of large faciocervical scar.

ABSTRACT

In recent years, as a powerful supplement to the randomized controlled trial (RCT), real world study (RWS) has received more and more attention. However, in the field of chronic wounds, most of the patients have complex condition, and the strict inclusion and exclusion criteria of RCT were lack of practical application values. The RWS provides data closer to the real medical environment in clinical medical practice, drug and medical device supervision, and health technology evaluation. However, RWS has some problems that need to be resolved, such as inconsistent diagnostic criteria and unclear research endpoints. In addition, RWS in chronic wound research in China seems to have not really started yet, and institutions at all levels need to work together to promote the development of RWS.

ABSTRACT

At the beginning of 2022, the first issue of the renamed journal-Chinese Journal of Burns and Wounds is published successfully, the editor-in-chief, Prof. Gaoxing Luo, explains the purpose, reason and necessity in the frontispiece to change the name of the journal from Chinese Journal of Burns to Chinese Journal of Burns and Wounds. Meanwhile, the unshakable and authoritative academic function and position of the journal in the discipline of burns not only in China but also in the world is illustrated. In fact, wound repair and regeneration is one of the most important and skillful tasks for burn experts, which has been also the main published content of the journal since it was founded in 2000. In order to meet the needs of the development of the discipline of burns and wounds and to make the name of the journal much more consistent with the published content, the journal is renamed as the new one without any changes of aim or scope of the publication. We believe that the journal with the new name will grow better and faster, and will set up a much more valuable academic platform for the development and talent cultivation for the disciplines of burns and wounds in the future.

ABSTRACT

Innovation and translation application are important topics that have been discussed repeatedly in national community of science and technology in recent years. We do a systemic review about the research and development history of growth factors, their application in trauma and burn management in China, and the conception and experience about the establishment of "Chinese way" for trauma and burn management in the process of constructing a disciplinary system for wound treatment with Chinese characteristics. It is our hope that these precious experiences will provide references and inspiration to our peers, especially the young generation in their research.
