In order to promote the development of hair transplantation, particularly the establishment of standards, the Hair Transplantation Expert Group of Plastic and Aesthetic National Medical Quality Control Center invited experts in the field of hair transplantation across China and formed a draft of the Expert Consensus on Standard Terminology for Hair Transplantation based on the collation of relevant literature and monographs. By combining Delphi methodology and consensus meetings, the expert group conducted several rounds of consultations on issues such as follicular unit anatomy, harvesting, dissection, and implantation, ultimately presenting 54 terminologies. This consensus considers the original Chinese and English meanings as well as the professional characteristics of terms used in hair transplantation, highlights the unique features and advantages of hair transplantation, and preserves its essence while promoting innovation, with the hope of providing valuable reference for clinical researchers engaged in hair transplantation both domestically and internationally, and better facilitating the standardization and advancement of the field.

The oral and maxillofacial region comprises a variety of organs made up of multiple soft and hard tissue, which are anatomically vulnerable to the pathogenic factors of trauma, inflammation, and cancer. The studies of this intricate entity have been long-termly challenged by a lack of versatile preclinical models. Recently, the advancements in the organoid industry have provided novel strategies to break through this dilemma. Here, we summarize the existing biological and engineering approaches that were employed to generate oral and maxillofacial organoids. Then, we detail the use of modified co-culture methods, such as cell cluster co-inoculation and air-liquid interface culture technology to reconstitute the vascular network and immune microenvironment in assembled organoids. We further retrospect the existing oral and maxillofacial assembled organoids and their potential to recapitulate the homeostasis in parental tissues such as tooth, salivary gland, and mucosa. Finally, we discuss how the next-generation organoids may benefit to regenerative and precision medicine for treatment of oral-maxillofacial illness.

Polymorphism refers to the simultaneous and frequent existence of two or more discontinuous variants or genotypes or alleles in a biological population, also known as genetic polymorphisms or genes Polymorphism. This gene polymorphism may have a certain degree of influence on the pharmacokinetics and pharmacodynamics of the drug. The study of genomics plays an important role in realizing personalized, patient-oriented precision medicine treatment. Population model analysis is to use a modeling method to quantitatively describe the correlation and variability between pharmacokinetic and pharmacodynamic parameters and individual characteristics and to quantify the impact of covariates. At present, this method has been widely used. This paper systematically introduces the application examples of using the population model approach to assess the effects of genetic polymorphisms on the drug PK/PD.

As the second most common cause of death in the world, cancer has become a persistent public health challenge. The incidence and mortality in different countries and regions or of multiple cancer types are significantly different, which is closely related to economic development level, lifestyle and environmental factors. A large number of epidemiological studies have focused on cancer burden, epidemic pattern, etiology and prevention, which is very important for the government to formulate cancer prevention policies based on medical evidence and protect population health. Therefore, based on the latest epidemiological publications, this paper reviews the incidence and mortality of cancer as well as the time trend in major countries and areas.

Objective To analyze the secular trends of pancreatic cancer incidence and mortality in Changning district of Shanghai from 1974 to 2013. Methods We calculated the age-standardized rates of incidence and mortality and the average annual percent changes for pancreatic cancer using Segi's world standard population and the data from Shanghai Cancer Registry. Age-period-cohort model was constructed to further assess the effect of age, diagnosis period and birth cohort on the secular trends of pancreatic cancer incidence and mortality. Results During 1974-2013, the age-standardized incidence and mortality rates were 6.49/10⁵ and 6.01/10⁵ in male, 4.83/10⁵ and 4.57/10⁵ in female, respectively. The age-standardized incidence was increased by 0.8% per year in male during past 40 years, while there was no change in mortality. The age-standardized incidence and mortality rates were increased by 1.6% and 1.3% per year in female. After adjusting the effects of diagnosis period and birth cohort, the incidence and mortality rates of pancreatic cancer increased by about 11% every 5 years older in both male and female. Diagnosis period and birth cohort had no statistical impact on the incidence and mortality of pancreatic cancer. Conclusion The age-standardized incidence of pancreatic cancer shows significantly rising trends during 1974-2013 in both male and female in Changning district of Shanghai, as well as the age-standardized mortality in female. The incidence and mortality rates also increase with age.

Patients seeking implantation often have several systemic diseases, which will introduce complications to treatment. This paper reviews the risk assessments and prevention of systemic diseases in patients with oral implant therapy with the relevant literature. The patients with cardiovascular diseases are prone to stroke and cardiac arrest, and anticoagulants and antihypertensive drugs will complicate cases. The potential risks of endocrine system diseases are infections and crises caused by unstable hormone levels. The risks of respiratory diseases are dyspnea and swallowing devices. The difficulty of treating patients with neuropsychiatric diseases is attributable to poor cooperation and adverse effects of the drugs. Bone and joint system diseases may decrease the success of implantation. Hematological system, digestive system and kidney diseases may lead to hemorrhage. By inquiring about detailed medical and medication history, evaluating vital signs and detecting important objective indicators, performing targeted measures, discussing with specialists, and observing patients closely, clinicians can avoid the abovementioned risks.

OBJECTIVE: To explore the genetic basis of cerebral palsy (CP). METHODS: A pair of twins with cerebral palsy and different phenotypes were subjected to whole genome sequencing, and other 8 children with CP were subjected to whole exome sequencing. Genetic variations were screened by a self-designed filtration process in order to explore the CP-related biological pathways and genes. RESULTS: Three biological pathways related to CP were identified, which included axon guiding, transmission across chemical synapses and protein-protein interactions at synapses, and 25 susceptibility genes for CP were identified. CONCLUSION The molecular mechanism of CP has been explored, which may provide clues for development of new treatment for CP.
