The apprentice system is the principal succession method of ancient Chinese medicine. Masters pass down knowledge via verbal instructions as well as personal deeds, and apprentices are unconsciously influenced deeply within by what they see and hear from masters. That is where the strong point of the system. However, at the same time, apprentices are confined by their master’s instructions and learn only a part of the knowledge. It is the profound meaning rather than the form, that truly represents the modern value of the system. Traditional Chinese medicine stresses the cultivation of medical ethics, purification of learning motivation, study of classic works, solid foundation of basic skills and clinical practice. It also advocates that apprentices should be led and taught in accordance to his aptitude.

There are more than 70 species of flaviviruses, including Zika virus, Dengue virus and Japanese encephalitis virus, and more than 33 species are known to be capable of infecting humans. Only three flavivirus vaccines have been approved, and there is a lack of safe and effective vaccines for most flaviviruses. Adenovirus-vectored vaccines have high safety, low cost, and convenience to store and transport. Currently, two adenovirus-vectored Zika vaccines are under early clinical trials, and adenovirus-vectored vaccines for Dengue virus, Japanese encephalitis virus, West Nile virus and yellow fever virus are still in the phase of animal experiment. In the development of adenovirus-vectored flavivirus vaccines, there are still problems of pre-existing immunity to adenovirus, the insufficient immunogenicity of adenovirus vectors and the antibody-dependent enhancement effects among flavivirus. Based on relevant publications from January 2006 to June 2023, this article reviews the current status, challenges and solutions of the research into adenovirus-vectored flavivirus vaccines, so as to provide the reference for the development of relevant vaccines.

Microarray technology, used in microorganisms detection with its advantages of rapid detection, high sensitivity, high-throughput and low cost, has been applied in environmental microbial community research widely in past few years. It focuses on investigation of structure, diversity, function, dynamics of microbial populations within complex environmental samples. Furthermore, it also reveals their responses and adaptation to environmental perturbations such as climate change, toxic contaminants. According probe design patterns, several types of microarrays, such as phylogenetic oligonucleotide arrays (POAs), functional gene arrays (FGAs), metagenomic array(MGA) and community genome arrays (CGAs) have been constructed for environmental studies. This review discusses applications of microarrays to environmental microbial populations research along with its potential for screening of specific microorganisms, gene or expression functional gene representing different environmental microbial populations.

ObjectiveTo investigate the effect of mild hypothermia on neuron specific enolase (NSE) and superoxide dismutase (SOD) in serum of patients with large-area cerebral infarction.Methods160 cases with large-area cerebral infarction were divided into the treatment group and control group with 80 cases in each group. Patients of the control group were treated with routine therapy. Those of the treatment group were added with mild hypothermia therapy (MHT). The scores of NIHSS were assessed and NSE and SOD in serum were examined before treatment and 7, 14 and 30 days after treatment in two groups.ResultsThe NIHSS score of the treatment group was significantly lower than that of the control group ( P<0.05), and NSE level decreased, SOD vitality increased in the treatment group. Other indexes such as respiratory, pulse, serum kalium and etc of two groups were not different ( P>0.05).ConclusionMHT can improve he nerve function of patients with large-area cerebral infarction recovering and improve prognosis.

Bosentan is a non-selective endothelin receptor antagonist,which plays an important role in the treatment of children with pulmonary arterial hypertension.Bosentan has shown to improve exercise capacity,hemodynamics and reduce pulmonary vascular resistance in pediatric patients.The main adverse effect is less severely comparing with the adult.The combination of bosentan with other drugs can improve the life quality furtherly.Further study of large-scale trials needs focus on the long-effects of bosentan,the ideal period of therapy and the effects of combination therapy in children.

Objective To investigate the correlation between patient' s age and expression of Ki-67 or microvessel density in primary hepatocellular carcinoma.Methods The expression level of Ki-67 and the microvessel density in the hepatocellular carcinoma tissues were detected by immunohistochemical method,and the correlation between age and expression of Ki-67 or microvessel density were analyzed.Results In 48 cases of hepatocellular carcinoma tissues,Ki-67 expressed to varying degrees,but the positive rate was 83.3 ％ (40/45),and there was no expression in corresponding noncancerous tissues (P ＜ 0.01).Microvessel density marked by CD34 in cancer tissues and noncancerous tissues were 32.17±8.06 and 10.83±2.85 respectively.Microvessel density of cancer tissues was higher than noncancerous tissues (P ＜ 0.01).Both levels of Ki-67 expression and microvessel density in hepatocellular carcinoma were negatively correlated with the age (r =-0.418,P =0.003 and r =-0.443,P =0.002 respectively).Conclusion Both levels of Ki-67 expression and microvessel density in hepatocellular carcinoma are negatively correlated with patient' s age,which may suggest worse prognosis for the younger patients.

To treat hallux valgus, minimally invasive osteotomy on 1st metatarsal neck,immobilization with "8-shape" bandagev was performed, and the effect was definited. The principles of osteotomy stability were analyzed from the osteotomy position, methods, direction and angle. The grinding drill was used to increase friction coefficient between the ends of osteotomy. Correct direction of osteotomy and suitable angle were the key point of stability. The immobilization with "8-shape" bandage complied with the principle of elastic fixation created the conditions for the slight movement of the osteotomy ends. Compared with internal fixation ,it was better on osteotomy healing,and the osteotomy ends were stable and healed with cartilage
