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.

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.

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.

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.

OBJECTIVE： To prepare pefloxacin mesylate eye drops.METHODS： The content of pefloxacin was determined with UV－ spectrophotometry.The therapeutic effect of the eye drops was observed in 170 out－ patients.RESULTS： The linearity range was 2～ 14μ g/ml with a regression equation of A=0.1 018C and r=0.9 999(n=7).The average recovery was 99.64％ with a RSD of 0.43％ .After treatment,150 out－ patients recovered,16 out－ patients improved and 4 out－ patients had no efficiency with a total effective rate of 97.6％ .CONCLUSION： The eye drops has definite therapeutic effect.The UV－ spectrophotometry method is simple,rapid and accurate in determination of the content and no special reagent is needed.

Objective To analyse the cognitive dysfunction early after non-cardiac surgery in elderly. MethodsEighteen elderly patients undergoing selective non-cardiac surgery were investigated. General anesthesia was used in 11 patients and combined epidural-spinal anesthesia in 7 cases. The operations involved orthopedic, thoracic, abdominal and urologic surgeries. The patients were premedicated with phynoharbital 0. 1g and scopolamine 0. 3mg. Results All patients suffered from typical POCD that occurred during 1 to 3 days after operation. The symptoms were more severe at night. The patients with POCD were treated effectively with intravenous injection of midozolam and muscle injection of haloperidol in 15 cases. The symptoms of POCD were attenuated by injection of pethidine in 2 cases. One case had to be given intravenous infusion of propofol continually for 16 hours. All patients were cured without psychological complications before discharge Conclusion POCD is a common complication in the elderly and should be treated actively.

Objective To investigate the inhibitory effects of RNA silencing via adenovirusmediated angiotensin Ⅱ receptor subtypes shRNA(Ad-ATlaR-shRNA and Ad-ATlbR-shRNA)in mice brainstem nucleus tractus solitarius(NTS)in vivo. Methods C57BL mice were used as animal model.The microinjection into the nucleus of NTS was adopted.Two groups of male C57BL mice(n =7,n=8)were selected.After 10 days of microinjection,mice were killed and their brain tissue were fixed and sectioned.The levels of ATlaR mRNA and ATlbR mRNA at both sides of NTS were examined by in situ hybridization. Results The expression of ATlaR mRNA was significantly inhibited from 1.81/μCi/mg to 0.71μCi/mg[(61.6±6.8)%,P<0.01]by Ad-ATlaR-shRNA.Meanwhile,ATlbR mRNA expression was consistent at both sides,with no significant difference(P>0.05)after Ad-ATlaR-shRNA microinjection.ATlbR mRNA expression at the side with AdATlbR-shRNA injection was significantly inhibited from 10.28/μCi/mg to 4.97μCi/mg[(51.6±5.2)%,P<0.01]by Ad-ATlbR-shRNA.Meanwhile,ATlaR mRNA probe were consistent at both sides,with no significant difference(P>0.05). Conclusions The results show that both AdATlaR-shRNA and Ad-ATlbR-shRNA inhibit the corresponding receptor mRNA expression,and there is no cross-action for each other.

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 To explore the expression and clinical significance of chromogranin A (CgA) and synaptophysin (Syn) in gastroenteropancreatic neuroendocrine tumors (GEP-NET).MethodsThe data of sixty-six GEP-NET patients treated in the First Affiliated Hospital of Nanjing Medical University were collected between Jan.2003 and May 2009.The expression of CgA and Syn in the tissue of GEP-NET was detected by immunohistochemistry, and its association with clinicopathological characteristics and prognosis of GEP-NET were analyzed.Results In these 66 patients,the positive rate of Syn (87.9％,58/66) was higher than that of CgA (71.3％,47/66,x2 =5.63,P=0.02).CgA and Syn were simultaneously expressed in 64.6％ patients (42/66).In the tissues of GEP-NET,the expression of CgA was related with lymph node metastasis and TNM stages,not related with patients' gender,age,tumor location,function,degree of differentiation,tumor size,infiltration and distant metastasis. Syn was not related with all the above clinicopathological parameters.Three-year survival rate in CgA negative group (47％) was significantly lower than that in positive group (78％,x2 =0.00,P=0.01).ConclusionsSyn was more sensitive than CgA in the diagnosis of GEP-NET.CgA in some extent indicates the prognosis of GEP-NET.
