The mental health situation in Chinese populations was analyzed, followed by an elaboration on the feasibility, methods and measures to carry out free-reading therapy in provincial mental disease hospital libraries.

The inhibitory effects of total glucosides of Moutan Cortex (TGM) and to talglucosides of Paeony Lactiflora (TGP) on osmotic hemolysis and oxidative hemolysis induced by hydrogen peroxide were studied. TGM at lower concentration and TGP could inhibit osmotic hemolysis significcantly, but higher concentration (100mg ? L-1) of TGM had a hemolytic activity. TGM and TGP could inhibit hemolysis induced by H2O2 significantly,but TGM was more effective than TGP. TGM .TGP and Vit E all could inhibit lipid peroxidation and glutathione depletion, induced by H2O2, on erythrocytes.

AIM To study the therapeutic effects of Deketoprofen trometamol (D KPT) on adjuvant arthritis (AA) and its side effects on gastroduodena. METHEDS The change of primary and secondary inflammatory and the injury effect of gastroduodena treated with D KPT were observed. The effect of D KPT on prostaglandin E 2 (PGE 2) produced by peritoneal macrophage (PM) on AA rats in vitro was also observed. RESULTS D KPT (2 5, 5, 10 mg?kg -1 ) significantly inhibited primary inflammatory, secondary inflammatory and multiple arthritis of AA rats. D KPT(10 -8 ,10 -7 ,10 -6 ,10 -5 ,10 -4 mol?L -1 )inhibited the elevated PGE 2 released from PM of AA rats in vitro . D KPT (10 mg?kg -1 ) significantly injured gastroduodena on AA rats, but the degree of injuries was less than that of ketoprofen (KP) (10 mg?kg -1 ). CONCLUSION D KPT has therapeutic effects on AA rats, and its injury effect on gastroduodena is less than that of KP.

Findings in epigenetic changes in meylodysplastic syndromes (MDS) and the development of demethylating drugs provide a new approach to the treatment of MDS.

Due to good mechanical properties and biocompatibility, tissue engineering scaffolds have become the vital method for repairing and regenerating articular cartilage defects. With the continuous development of tissue engineering technology, many scaffolds preparation and formation methods have been developed and tested in the past decade, however, the preparation of ideal regenerative scaffolds remain controversial. As load-bearing tissue inside the body joints, the matrix structure and cell composition of articular cartilage are hierarchical, and there are several smooth natural gradients from the cartilage surface to the subchondral bone layer, including cell phenotype and number, specific growth factors, matrix composition, fiber arrangement, mechanical properties, nutrient and oxygen consumption. Therefore, in the design of regenerative scaffolds, it is necessary to achieve these gradients to regenerate articular cartilage in situ. In recent studies, many new biomimetic gradient scaffolds have been used to simulate the natural gradient of articular cartilage. These scaffolds show different mechanical, physicochemical or biological gradients in the structure, and have achieved good repair effects. The related articles on tissue engineering for the treatment of articular cartilage defects were retrieved by searching databases with key wordsarticular cartilage injury, cartilage repair and gradient scaffolds. In this work,the structural, biochemical, biomechanical and nutrient metabolism gradients of natural articular cartilage were studied and summarized firstly. Then, the latest design and construction of articular cartilage gradient scaffolds were classified. Besides that, the material composition (such as hydrogels, nanomaterials, etc.) and the preparation process (such as electrospinning, 3D printing, etc.) of grandient scaffolds were further enhanced. Finally, the prospect and challenge of biomimetic gradient scaffolds in cartilage engineering are discussed, which provides a theoretical basis for the successful application of gradient scaffolds in clinical transformation.

Objective:To investigate the main postoperative complications, causes of death and the risk factors for survival in patient with benign end-stage lung diseases within 1 year after lung transplantation.Methods:A retrospective analysis was conducted to collect the clinical data of 200 patients with benign end-stage lung disease who underwent lung transplantation admitted to Wuxi People's Hospital Affiliated to Nanjing Medical University from May 2017 to October 2018. The main postoperative complications, survival and causes of death within 1 year after operation were analyzed. The Kaplan-Meier method was used to plot survival curves, and the Log-Rank test was used to compare the influence of factors, including recipient's gender, use of marginal donor lung, primary disease, preoperative combination of moderate to severe pulmonary hypertension (PAH), intraoperative extracorporeal membrane oxygenation (ECMO) support, surgical methods, intraoperative massive blood loss, postoperative complications [infection, primary graft dysfunction (PGD), acute rejection], on 1-year survival in patients who underwent lung transplantation. The multivariate Cox proportional hazards regression model was used to evaluate the risk factors of death within 1 year after lung transplantation.Results:Two hundred patients underwent successful lung transplantation. The major postoperative complications within 1 year after transplantation included infection in 131 patients, PGD in 20 patients, acute rejection in 57 patients, anastomotic complication in 26 patients and others (new onset diabetes, osteoporosis, etc.) in 53 patients. The 3-month, 6-month, and 1-year postoperative cumulative survival rates were 81.5%, 80.0% and 77.5%, respectively. Forty-five patients died during 1 year after operation, among whom 14 died of infection, 7 died of PGD, 8 died of acute rejection, 4 died of anastomotic complication, 3 died of cardio-cerebrovascular accident, 3 died of multiple organ failure, 2 died of respiratory failure and 4 died of other causes (traffic accident, etc.). The Kaplan-Meier survival analysis showed that recipient's gender, idiopathic pulmonary fibrosis (IPF) as the primary disease, preoperative combination of moderate and severe PAH, intraoperative ECMO support, intraoperative massive blood loss, postoperative complications (infection, PGD, acute rejection) were influencing factors for postoperative 1-year survival rate. The multivariate Cox regression model showed that male was the protective factor [hazard ratio ( HR) = 0.481, 95% confidence interval (95% CI) was 0.244-0.947, P = 0.034], IPF as the primary disease ( HR = 2.667, 95% CI was 1.222-5.848, P = 0.014), intraoperative use of ECMO support ( HR = 1.538, 95% CI was 0.787-3.012, P = 0.028), massive blood loss during surgery ( HR = 2.026, 95% CI was 0.976-4.205, P = 0.045) and postoperative infection ( HR = 3.138, 95% CI was 1.294-7.608, P = 0.011), PGD ( HR = 1.604, 95% CI was 0.464-5.539, P = 0.004), and acute rejection ( HR = 1.897, 95% CI was 0.791-4.552, P = 0.015) were the independent risk factors for death within 1 year after transplantation. Conclusions:One-year survival rates after lung transplantation are affected by recipient's gender, primary disease, preoperative combination of moderate and severe PAH, intraoperative ECMO support, intraoperative massive blood loss, and postoperative complications (infection, PGD, acute rejection). The male is the protective factor, while IPF as the primary disease, intraoperative ECMO support, massive blood loss during surgery and postoperative complications (infection, PGD, acute rejection) are independent risk factors for death within 1 year after lung transplantation.

The treatment of articular cartilage (AC) injury caused by various reasons is still a major clinical problem. The emergence of cartilage tissue engineering brings new hope for the treatment of AC injury. In general, AC tissue engineering can be divided into two categories, including cell-based tissue engineering and cell-free tissue engineering. Although cell-based tissue engineering can repair cartilage damage to a certain extent, existing therapeutic strategies still suffer from limited cell sources, high costs, risk of disease transmission, and complex procedures. However, the cell-free tissue engineering avoids these shortcomings and brings hope for in-situ AC regeneration. Non-cellular tissue engineering is mainly used to recruit endogenous stem cells/progenitor cells (SCPCs) to reach the site of cartilage injury, and provide a suitable regenerative microenvironment to promote cell proliferation and chondrogenic differentiation, then the maturation of new cartilage tissue was promoted. Therefore, it is also called as cell-homing in situ tissue engineering. Successful recruitment of endogenous SCPCs is the first step in in-situ cartilage tissue engineering. This review aims to introduce chemokine response of cartilage injury, systematically summarize traditional chemoattractant (chemokines and growth factors etc.) and emerging chemoattractant (functional peptides, exosomes and nucleic acid adapters etc.), evaluate the combination mode between chemoattractant and delivery devices, discuss the prospects and challenges of chemoattractant-mediated in situ tissue engineering and provide theoretical basis for the design of endogenous SCPCs homing-based in situ tissue engineering.
