As a non-invasive examination method, anterior segment optical coherence tomography (AS-OCT) has huge potential in detecting neoplastic epithelial lesion.With AS-OCT, detection and differentiation of ocular surface squamous neoplasia (OSSN) within ocular surface pathologies can be achieved and the diagnosis rate is comparable to that of biopsy.With the development of technology, AS-OCT imaging mode has developed from time-domain OCT to spectral-domain OCT with higher penetrance and resolution, the high-quality images of which are helpful to distinguish the benign and malignant OSSN, enhance the detection rate of OSSN, improve the differentiation of ocular surface tumors, and thus improve the diagnostic accuracy of OSSN.In addition, AS-OCT can help optimize the treatment regimen and effectively monitor the outcome of the disease in the clinical management stage, such as monitoring the recurrence of OSSN and evaluating chemotherapy.In this article, the morphological features of OSSN, the advantages and disadvantages of OSSN auxiliary examinations, the development of AS-OCT, the specific manifestation of OSSN on AS-OCT, the application of OCT in atypical OSSN, as well as the value and limitation of AS-OCT in the diagnosis and management of OSSN were reviewed.

Objective: To study the determinants that affect patient satisfaction to rural doctors. Methods:Based on survey data of Liupanshui City, Guizhou Province, structural equation modeling analysis was adopted, and the study was mainly from the following four aspects:the image of rural doctors, service quality, quality of diagnosis and treatment, and harmonious doctor-patient relationships. Results: The study found that the quality of diagnosis and treatment had the greatest direct impact on rural patient satisfaction, followed by service quality, the image of ru-ral doctors and harmonious doctor-patient relationships;rural patient satisfaction has a significant impact on rural pa-tient loyalty. Conclusion:Rural patient satisfaction and loyalty to rural doctors is mainly based on kinship and geopo-litical relations;given the state of medical technology, the medical environment, medical equipment, service aware-ness and other restrictions, rural doctors cannot fulfill the “gatekeeper” role, and consequently, the primary health-care system has been severely affected.

Rheumatoid arthritis is one of the most critical diseases that impair the quality of patients' life, but its pathogenesis has not yet been fully understood. Osteopontin (OPN) is an extracellular matrix protein containing Arg-Gly-Asp (RGD) sequence and has been recently recognized as a potential inflammatory cytokine. It is discovered that OPN plays an important role in the pathogenesis of rheumatoid arthritis. It is a bridge between bone and the immune system. This paper reviewed the pivotal role that OPN plays in the pathogenesis of rheumatoid arthritis.

TCM believes that apoplexia is a disease of deficiency in origin and asthenia in superficiality. The deficiency is mainly the Qi deficiency and the superficiality is turbid phlegm retention and blood stasis due to Qi deficiency. Therefore, the therapeutic method should treat the origin of apoplexy as well as its superficiality. Based on the pathogenesis of apoplexy of Qi deficiency and phlegm-blood stasis, Naomaitai Capsule was formulated with the functions of supplying Qi to consolidate the origin, activating blood flow, dissipating phlegm, dredging collaterals, and stopping endogenous wind.

【Objective】 To investigate the control rate of blood glucose and its influencing factors in type 2 diabetes mellitus patients in Yulin area. 【Methods】 We selected the adult type 2 diabetes patients who visited our hospital from May 2020 to December 2021 as the subjects. Then we collected their basic information (gender, age, household income, type of medical insurance payment, education level, and duration of disease), measured their height and weight, calculated their body mass index (BMI), detected HbA1c, and measured their subcutaneous and visceral fat. The Chi-square test and multivariate Logistic regression methods were used to analyze the influencing factors. 【Results】 The total attainment rate of HbA1c (HbA1c<7%) among 877 adults with type 2 diabetes was 13.34%. The Chi-square test showed that statistical differences in the attainment rate of HbA1c among different ages, family annual income, type of medical insurance, and duration of disease. Further unconditional multivariate Logistic regression analysis model results showed that the HbA1c attainment rate in 18-44 years old group was 0.418 times higher than that in ≥60 years old group (95% CI=0.219-0.799, P=0.008). The HbA1c compliance rate of patients with employees’ medical insurance was 1.744 times that those with residents’ medical insurance (95% CI=1.131-2.782, P=0.013). The HbA1c attainment rate of diabetic patients with an annual family income of 30 000 yuan to 100 000 yuan was 1.873 times (95% CI=1.074-3.266, P=0.027), and with an annual family income of more than 100 000 yuan was 2.649 (95% CI=1.299-5.404, P=0.007) times than that of diabetic patients with less than 30 000 yuan. 【Conclusion】 The blood glucose control rate in adults with type 2 diabetes mellitus in Yulin area is lower compared with the level of the nation and other regions. Age, annual household income, and type of medical insurance payment are independent influencing factors.

Combined antiretroviral therapy ( cART) is widely used for infections of human immune deficiency virus ( HIV) .However , some antiviral drugs can not reach the effective concentrations in central nervous system due to the hinder of blood-brain barrier ( BBB) , resulting in the formation of viral reservoir in central nervous system .BBB is formed by human brain microvascular endothelial cells ( HBMVECs ) , which are connected by tight junction and a thick basement membrane , and astrocytic end-feet.This paper reviews possible mechanisms of BBB hindrance and anti-HIV drug efflux by transport proteins , as well as effective methods to deliver antiretroviral drugs into brain , including the application of nano technology .

Objective To construct pET21a-sBAFF by cloning the extracellular regions of 134-285 amino acids of BAFF, a member of human TNF family, and then express the gene in prokaryotic cells and purify the expressed product.Methods cDNA of K562 cell line was used as the template to amplify sBAFF gene to construct pET21a-sBAFF.Expression of sBAFF in E.coli BL21 was induced by IPTG, and the expressed proteins were assayed by SDS-PAGE.The bacteria were analyzed by sonication, and the target proteins mainly existed as inclusion bodies.Then sBAFF was purified by Ni2 +-IDA affinity chromatography.SDS-PAGE electrophoreses displayed that the expressed sBAFF migrated with a relative molecular weight of 18000.ResuIts The induction parameters such as temperature and inducing time were optimized.The target protein accounted for 38.59%of the total bacterial proteins.After refolding, 38.14% of sBAFF proteins were polymerized as an active trimer.The dimer form of sBAFF, which is representative of wrongly refolded product, accounted for very few.ConcIusion The expression and purification of BAFF which formed active trimer after refolding pave the way for its further function study and provide a novel approach for the development of BAFF-targeted therapeutics for autoimmune diseases.
