Regulatory B cells(Breg) are a subgroup of B lymphocytes and characterized by their immunosuppressive capacity. The regulation of immune response by Breg plays a critical role in the mouse and human immune systems. Previous studies on Breg mainly focus on autoimmune diseases and tumors, but in recent years, the role of Breg in chronic infectious diseases has attracted attention. This review summarized the phenotypes, modes of action and the role of Breg in the process of chronic infectious diseases aiming to provide a new sight for research on immunotherapy for chronic infectious diseases.

ABSTRACT: "Association of the kidney with the ears" is central to the traditional Chinese medical (TCM) theory of the viscera and their manifestations. Previous studies have shown that thyroxin, aldosterone, calcium and iron might be the material basis of the correlation between the kidney and the ears. Due to restriction in research techniques and methods, there has been no further progress in this research field, whose modern biological mechanisms and scientific connotations have not been explained clearly. In recent years, the progress of biological techniques and research on kidney essence provided promising opportunities for research of the association between the kidney and the ears. This article summarized the study progress of "association of the kidney with the ears" theory and posed some meaningful study thoughts. Presbycusis is a kind of degenerative disease caused by aging, which is one aspect of aging of the human body. Because aging is considered as physiological "kidney deficiency", presbycusis can be regarded as a model of "kidney deficiency" deafness. In conclusion, investigating the correlation between "kidney deficiency" and presbycusis using biotechnology systems combined with "essence of kidney", should provide a sound basis for study of the theory of the relationship between the kidney and the ears. This will provide new and valuable information for the modern biological research about the theory of visceral associations in TCM.

Objective To detect the genetic diversity and prevalent strains of Mycobacterium tuberculosis isolates from Tibetan patients in Tibet and to analyze factors associated with prevalent strains.Methods A total of 577 Mycobacterium tuberculosis isolates were genotyped by spacen oligonucleotide typing (spoligotyping) and the results were analyzed with BioNumerics software (Version 5.0) and compared with the international spoligotype database of SITVIT2.Results Among the 577 cases of Tibet patients,329 were male and 248 were female.Based on spoligotyping,23 different spoligotypes were identified among 577 Mycobacterium tuberculosis isolates,with a genetic diversity of 3.99 ％.The majority (97.57％,563/577) of the isolates belonged to four known families,such as Beijing family,T family,CAS family and MANU2 family.The remaining 14 isolates had 11 novel spoligotypes.522 (90.47％)isolates belonging to Beijing family presented with 7 spoligotypes,resulting in the genetic diversity of Beijing family of 1.34％.With high similarity,Beijing family strains could be clustered into one genotype;among non-Beijing family strains,strains belonging to T family and MANU2 family were similar and could be clustered into one genotype.Changdu had the highest prevalence (97.83％) of Beijng family strains.In this study,the occurrence of Beijing family strains was not associated with age,sex,bacillus CalmetteGuerin vaccination or treatment history (P=1.00,0.36,0.83 and 1.00,respectively).Conclusions In this study,the genetic diversity of Tibetan Mycobacterium tuberculosis is low and Beijing family strains are highly prevent in Tibet,by classical spoligotyping.

Objective To observe the clinical efficacy of low-dose erythromycin combined with salmeterol-fluticasone in the treatment of stable COPD, focus on the quality of life and respiratory function of patients.Methods 87 patients with stable COPD admitted to Hangzhou Red Cross Hospital from January 2014 to January 2016 were selected.Patients were divided into two groups by therapeutic methods, observation group ( salmeterol-fluticasone+erythromycin) 46 cases and control group (salmeterol-fluticasone) 41 cases.Six months of treatment, the quality of life of two groups of respiratory function assessment, acute COPD and peripheral inflammatory factor and other indicators of change.Results After treatment, both of the two groups got significantly decreased in SGRQ and MMRC scores, while the observation group was significantly lower than the control group, the difference was statistically significant(P<0.05).After treatment, FEV1/FVC%levels were significantly increased in both groups, but the observation group was significantly higher than the control group, the difference was statistically significant(P <0.05).The cumulative incidence of acute exacerbation of COPD was 10.87%(5/46) in the observation group, which was significantly lower than that in the control group 29.27%(12/41), the difference was statistically significant(Log-rankχ2 =4.833, P=0.028).After treatment, the levels of IL-1βand TNF-αin the peripheral blood of the patients in the observation group were significantly lower than those in the control group, the difference was statistically significant (P <0.05).Conclusion In the treatment of stable COPD, low-dose erythromycin could significantly improve the clinical efficacy, improve the quality of life and respiratory function.

The effects of Verapamil ( Ver ) . Aspirin ( ASA ) and ASA+ Ver on platelet aggregation and generation of thrombosis were studied. ASA and Ver inhibited rabbit platelet aggregation in vitro and rat platelet aggregation in vivo induced by ADP, also prolonged the occlusion time of thrombosis that was induced electrically in the carotid artery of the rat, and reduced the death rate resulted from pulmonary thrombosis that was induced with inducer composed of collagen and epinephrine iv in mice. The effects of Ver and ASA were markedly increased when combined, meanwhile all showed good dose-dependant manner.

Since local chemotherapy and sustained release chemotherapy have been put forward, a number of sustained-release drug delivery systems have been developed with regard to the releasing effect in vitro and in vivo, as well as the lethal effect on the tumor cells. This study reviews the merit of sustained release chemotherapy and sustained release drug delivery system of malignant bone tumor both in vitro and in vivo.

OBJECTIVE:To observe the efficacy and safety of clopidogrel combined with aspirin in the treatment of transient ischemic attack in the elderly. METHODS:90 elderly patients with transient ischemic were randomly divided into observation group(50 cases)and control group(40 cases). All patients received conventional treatment,statins,low molecular weight dextran and urokinase,etc.,symptomatic treatment was conducted for patients combined with other underlying diseases. Based on it,con-trol group received 100 mg Aspirin enteric-coated tablet,once a day;observation group additionally received 75 mg Clopidogrel bi-sulfate tablet,once a day. No other antiplatelet drugs were allowed. They treatment for 6 months. Clinical efficacy,platelet func-tion indexes(CD63,CD62p)before and after treatment,recurrence rate and incidence of cerebral stroke after 6 months follow-up in 2 groups were observed,and the incidence of adverse reactions was recorded. RESULTS:The total effective rate in observation group was significantly higher than control group,recurrence rate and incidence of cerebral stroke were significantly lower than con-trol group,the differences were statistically significant(P<0.05). After treatment,CD63 and CD62p levels in 2 groups were sig-nificantly lower than before,and observation group was lower than control group,the differences were statistically significant(P<0.05). And there were no obvious adverse reactions during treatment. CONCLUSIONS:Based on conventional treatment,clopido-grel combined with aspirin shows better efficacy than aspirin alone in the treatment of transient ischemic attack in the elderly,it can reduce the incidence of cerebral stroke and recurrence rate,with good safety.

The pathological changes of hallux valgus are diversity, including adduct of metatarsus primus, increasing of the intermetatarsal angle between the first and second metatarsal bones, increasing of hallux valgus angle, dislocation of sesamoides, lost of soft tissue balancing. X-ray is the most important method to measure the pathological changes of hallux valgus. The multiformity of hallus valgus pathological changes makes manner of repairing variety. The main methods include operation on soft tissue, osseous surgery, fusion of joint and figuration of joints. The selection of the surgical methods should be individualization according to the idiographic pathological changes of hallux valgus patients.
