Objective We discussed the influence of diary therapy for out-of-hospital rehabilitation of schizophrenia patients with first hospitalization. Methods Ninety schizophrenia patients with first hospitaliza-tion and who were during rehabilitation period were randomized into the intervention group and the control group with 45 cases in each group.The two groups both received systemic antipsychotics medication.The control group adopted general health education while the intervention group got diary therapy based upon general health education.The treatment effect was evaluated by medical and nursing staff with abundant experience using the self-medication compliance questionnaire,the brief psychiatric rating scale(BPRS)and social disability screening schedule(SDSS)at the first day,6th month and first year after intervention. Results The total score of BPRS,SDSS,medication compliance and relapse rate in the intervention group was statistically better than those of the control group. Conclusions Diary therapy could facilitate the recovery of racial function,improve the medica-tion compliance,reduce the relapse rate and increase life quality for schizophrenia patients.

To study the chemical constituents of K. oblongifolia, silica gel column chromatography, MCI and Sephadex LH-20 were used to separate the 70% acetone extract of the stems of K. oblongifolia. The structures of the isolated compounds have been established on the basis of physicochemical and NMR spectroscopic evidence as well as ESI-MS in some cases. Twenty compounds were obtained and identified as heteroclitalignan A (1), kadsulignan F (2), kadoblongifolin C (3), schizanrin F (4), heteroclitalignan C (5), kadsurarin (6), kadsulignan O (7), eburicol (8), meso-dihydroguaiaretic acid (9), kadsufolin A (10), tiegusanin M (11), heteroclitin B (12), (7'S)-parabenzlactone (13), angeloylbinankadsurin B (14), propinquain H (15), quercetin (16), kadsulignan P (17), schizanrin G (18), micrandilactone C (19) and (-)-shikimic acid (20). Compouds 1, 5, 8, 11-15, 18 and 20 were isolated from this plant for the first time. Toxicity of compounds 1-10 were evaluated with zebrafish model to observe the effect on its embryonic development and heart function. The results showed that compounds 7, 9 and 10 caused edema of zebrafish embryo and decreased the heart rate of zebrafish, which exhibited interference effect on heart development of zebrafish.

BACKGROUND:Due to the sudden release and the rapid removal by proteases,platelet-rich plasma hydrogel leads to shorter residence times of growth factors at the wound site.In recent years,researchers have focused on the use of hydrogels to encapsulate platelet-rich plasma in order to improve the deficiency of platelet-rich plasma hydrogels. OBJECTIVE:To prepare self-assembled polypeptide-platelet-rich plasma hydrogel and to explore its effects on the release of bioactive factors of platelet-rich plasma. METHODS:The self-assembled polypeptide was synthesized by the solid-phase synthesis method,and the solution was prepared by D-PBS.Hydrogels were prepared by mixing different volumes of polypeptide solutions with platelet-rich plasma and calcium chloride/thrombin solutions,so that the final mass fraction of polypeptides in the system was 0.1%,0.3%,and 0.5%,respectively.The hydrogel state was observed,and the release of growth factors in platelet-rich plasma was detected in vitro.The polypeptide self-assembly was stimulated by mixing 1%polypeptide solution with 1%human serum albumin solution,so that the final mass fraction of the polypeptide was 0.1%,0.3%,and 0.5%,respectively.The flow state of the liquid was observed,and the rheological mechanical properties of the self-assembled polypeptide were tested.The microstructure of polypeptide(mass fraction of 0.1%and 0.001%)-human serum albumin solution was observed by scanning electron microscope and transmission electron microscope. RESULTS AND CONCLUSION:(1)Hydrogels could be formed between different volumes of polypeptide solution and platelet-rich plasma.Compared with platelet-rich plasma hydrogels,0.1%and 0.3%polypeptide-platelet-rich plasma hydrogels could alleviate the sudden release of epidermal growth factor and vascular endothelial growth factor,and extend the release time to 48 hours.(2)After the addition of human serum albumin,the 0.1%polypeptide group still exhibited a flowing liquid,the 0.3%polypeptide group was semi-liquid,and the 0.5%polypeptide group stimulated self-assembly to form hydrogel.It was determined that human serum albumin in platelet-rich plasma could stimulate the self-assembly of polypeptides.With the increase of the mass fraction of the polypeptide,the higher the storage modulus of the self-assembled polypeptide,the easier it was to form glue.(3)Transmission electron microscopy exhibited that the polypeptide nanofibers were short and disordered before the addition of human serum albumin.After the addition of human serum albumin,the polypeptide nanofibers became significantly longer and cross-linked into bundles,forming a dense fiber network structure.Under a scanning electron microscope,the polypeptides displayed a disordered lamellar structure before adding human serum albumin.After the addition of human serum albumin,the polypeptides self-assembled into cross-linked and densely arranged porous structures.(4)In conclusion,the novel polypeptide can self-assemble triggered by platelet-rich plasma and the self-assembly effect can be accurately adjusted according to the ratio of human serum albumin to polypeptide.This polypeptide has a sustained release effect on the growth factors of platelet-rich plasma,which can be used as a new biomaterial for tissue repair.

The meridian theory is the pioneer of clinical diagnosis and treatment of diseases in Traditional Chinese Medicine (TCM). From Shang Han Lun to Pi Wei Lun, the meridian theory has contributed important theoretical organization materials and clinical practice experience to the establishment of the diagnosis system of external and internal injuries. The acupoints contained in its clinical acupuncture and moxibustion record symptoms, and some laws summarized have been absorbed and used for reference. It shows the positive significance of its exploration in clinical diagnosis and treatment. A system of differentiation and treatment of external and internal injuries with acupuncture has not been formed, even though the meridian theory of TCM has a long history with many areas being explored, such as diseases, acupoints, acupuncture methods and stimulation amount. Therefore, this paper starts from the academic development history of meridians, reviews and analyzes the contribution and limitations of TCM acupuncture and moxibustion in the diagnosis and treatment of internal injury, in order to enlighten the current study and understanding of TCM.
