In recent years,considerable progress has been made in the treatment of multiple myeloma(MM).However,despite the current improved prognosis of this malignancy,it always ends in relapse and therefore new therapeutic approaches are urgently needed to overcome it.The chimeric antigen receptor(CAR)-T cells targeting B cell maturation antigen(BCMA),cluster of differentiation 19(CD19),cluster of differentiation 38(CD38) and kappa light chains have been evaluated,and have achieved remarkable results in clinical trials.However,even when MM is treated with CAR-T cell therapy,most patients eventually relapse,which is the greatest limitation of this therapy.This paperreviewedthe research progress,limitations and optimization of CAR-T cell immunotherapy in the treatment of MM.

Objective To interview the work feelings of the Middle youth patients with peritoneal dialysis. Methods Using the purposive sampling method, 11 patients were interviewed, and analyzed the content of the interview. After the interview, data were transcribed and extracted the keywords. Results Eight keywords were extracted, the patients had four positive feelings:self-perceived burden relived;more social support; more glad, negative feelings relived; peritoneal dialysis could be sure. 4 negative themes were extracted:tedious;had economic pressure;lack of self-realization;could not take the family burden. Conclusions Work can improve the living conditions of middle youth patients with peritoneal dialysis. More patients should be encouraged to return to work.

Objective To establish a HPLC method to determine the antiseptics in compound dexamethasone acetate cream and evaluate the usage rationality of antimicrobial preservatives. Methods The content of ethyl hydroxybenzoate was calculated by external standard with HPLC.The effectiveness of antimicrobial preservatives was measured according to the preservative effectiveness test in ChP(2015edition) by inoculating 5 kinds of test microorganisms including Pseudomonas aeruginosa,Escherichia coli,Staphylococcusaureus,Candida albicans and Aspergillusniger.Results The linear ranges of ethyl hydroxybenzoate was 6.63-132.6 μg/mL ( r =0.999 7 ) .The average recoveries was 99.2%.The samples from different batche had different antimicrobial effectiveness due to the content of ethyl hydroxybenzoate.Conclusion The described method can be used in the determination of the preservatives of ethyl hydroxybenzoate in compound dexamethasone acetate cream.At present the use of antibacterial agent is arbitrary, it is necessary to strengthen research and supervision.

Gefitinib and erlotinib are the first generation of targeted therapeutic agents approved for the treatment of advanced non-small cell lung cancer. Despite a dramatic initial response, most patients subsequently and ultimately become resistant to the drugs. Recent studies have proposed various mechanisms of such resistance, some of which related to a second mutation in epidermal growth factor receptor, aberrant activation of other tyrosine kinase receptors, bypassing signal pathways and constitutive activation of downstream signal molecules. Other researches also associated the drug resistance to internalization of epidermal growth factor receptor and changes in tumor microenvironment. Furture studies need to focus on overcoming or reversing resistance to the drugs and developing new targeted therapeutic agents.

A systematic comparative study ou the morphology and histology of the rhizomes of polygonatum including "Huangjing" and "Yuzhu" currently available on the Chinese market werepresented. The differences between this two types of herbal medicines were given.

Chronic constipation (CC) is one of the most common digestive diseases with high prevalence and long course.CC patients often suffer from sleep disorders and psychological problems such as anxiety and depression.Somatic and mental symptoms may affect with each other, so a vicious circle will develop to impair patients′ quality of life (QOL) and increase their economic burden.The article reviews the impact of chronic constipation on QOL and economic burden of patients, indicating that clinician should pay sufficient attentions on chronic constipation.

Objective:To explore the effects of levocarnitine adjunctive therapy on serum nutritional index and inflammatory factor level in maintenance hemodialysis patients. Methods:Totally 62 patients with hemodialysis were randomly divided into the observation group and the control group with 31 cases in each. The observation group was treated with 1g levocarnitine injection with intravenous in-jection after the dialysis, and the control group was treated with 0. 9% physiological saline injection with the same volume after the di-alysis. After 3-month treatment, the nutritional indices including Hb, Alb, TC, TG, LDL-C and HDL-C and the change in inflamma-tory factors including C-reactive protein (CRP), IL-6, IL-8 and TNF-α of the patients in the two groups were studied and compared. Results:After the treatment, the level of Hb and Alb was improved in the observation group (P<0. 05), while the level of TC, TG, HDL-C and LDL-C had no significant change (P>0. 05). All of the indices showed no significant change in the control group (P>0. 05). After the treatment, the level of Hb and Alb in the observation group was higher than that in the control group (P<0. 05). After the treatment, the level of CRP, IL-6, IL-8 and TNF-α was reduced in the observation group (P<0.05), while the control group had no significant changes in the indices (P>0. 05). All of the indices in the observation group was better than those in the control group (P<0. 05). Conclusion:Levocarnitine used in the treatment of patients with hemodialysis can effectively improve the nutritional status and inflammatory factors level without obvious effects on lipid metabolism, which is very important for the reduction of complication and the improvement of life quality, and worthy of clinical promotion.

Objective Research and analysis on the clinical effect of rehabilitation of linguistic disturbance of child cerebral palsy patients,mainly through the treatment of acupuncture.Methods Effect comparison between the treatments of acupuncture and the only common way of 121 cerebral palsy children.Results The treatment mainly by acupuncture was obvious better than the common one.Conclusions The treatment mainly by acupuncture is one of the effective ways of linguistic disturbance of infantile cerebral palsy,and there are good prospects and special advantages for the treatment of Traditional Chinese Medical Science

Objective:The experiment was designed to apply proteomics to analyze the signal transduction molecules in T lymphocyte strain JurkatD1.1 cells with the stimulation of prolactin.Methods:JurkatD1.1 cells were cultured in the presence of recombinant human prolactin(rhPRL).Phosphated metal affinity chromography(PMAC) and immunoprecipitation(IP) assay were applied to enrich phosphoproteins from the total cell lystates which were resolved by one-dimensional electrophoresis(1 DE) or 2 DE.The different bands and different spots in the gels between control group and rhPRL-treated group were excised,digested,and analyzed by MALDI-TOF mass spectrometry.Results:Three major protein bands were observed specifically in the rhPRL-treated group and other two major protein bands were observed specifically in the control group.The bands were excised and analyzed by MALDI-TOF mass spectrometry.Protein band a in rhPRL-treated group was successfully identified as hot shock protein 90(hsp90).Nine different protein spots which were observed in the 2 DE gels between the two groups were excised and analyzed by MALDI-TOF mass spectrometry.In the rhPRL-treated group the protein spot 4 was identified as nuclear receptor co-repressor 2 variant(NcoR 2 variant);The protein spot 5 was identified as galactose-1-phosphate uridyl transferase;And the protein spot 6 was identified as zinc finger ZIM3.Conclusion:Hot shock protein 90 participates the signal transduction pathways of prolactin.Nuclear receptor co-repressor 2 variant and zinc finger ZIM3 may play a role in the process of prolactin modulating target genes' expression.
