OBJECTIVE:To evaluate therapeutic efficacy and safety of chemotherapy combined with Xiaoaiping injection in the treatment of elderly patients with advanced gastric cancer. METHODS:60 elderly patients with advanced gastric cancer were collected from our department during 2012-2014,and then divided into union group and single group with 30 cases in each group. Single group was given irinotecan(CPT-11)150 mg/m2 added into 0.9%Sodium Chloride injection,and union group was addition-ally given Xiaoaiping injection 80 ml,qd,on the basis of single group. A treatment course lasted for 14 days,and both groups re-ceived 4 courses of treatment. The tumor markers,disease single rate,progression-free survival (PFS) and the incidence of ADR were compared between 2 groups. RESULTS:After treatment,the levels of CEA,CA199 and CA242 in 2 groups were significant-ly lower than before;the union group was significantly lower than the single group,with statistical significance(P<0.05). The dis-ease single rate of union group was 70.00%,which was significantly higher than that of single group (33.33%). PFS of union group was(11.23±2.17)months,which was significantly longer that of single group [(9.36±0.84)months],with statistical signif-icance(P<0.05). The incidence of leucopenia,alanine aminotransferase elevation,diarrhea,stomatitis and hand-foot syndrome in union group was significantly lower than in single group,with statistical significance(P<0.05). CONCLUSIONS:Xiaoaiping in-jection combined with irinotecan chemotherapy for advanced gastric cancer has obvious effect with a low incidence of ADR.

Objective To discuss the application value of the Nickel-Titanium patella concentrator(NT-PC) in surgical treatment of patellar fracture.Methods A retrospective analysis was made on clinical data of 32 cases of patellar fracture treated with the NT-PC in this hospital from January 2001 to December 2003.Results Re-examination of radiography at 12 weeks after surgery showed bone union was achieved in all the cases,with a smooth patellofemoral articular surface.The patella was preserved completely in all the comminuted fracture cases.According to the Lu's criteria,excellent and good outcomes were achieved in 26 and 6 cases,respectively,the rate of excellent or good results being 100%.The NT-PC was removed at 4 months ~ 2 years(mean,14 months) postoperatively without complications.Conclusions Application of NT-PC in the treatment of patellar fracture can preserve the comminuted patella completely,facilitate the reduction and fixation of the patellofemoral articular surface,and make early postoperative motions available.It is worthy of being recommended.

In recent years, there has been a growing emphasis on use of human adipose-derived stem cells (hADSCs) for cartilage tissue engineering owing to their ability to differentiate into chondrocytes, which is mainly induced by growth factors (GFs). In general, GFs for chondrogenic induction come from the transforming growth factor beta (TGF-beta) superfamily. To date, the most commonly used GFs for chondrogenes is TGF-beta1/3. However, the response of hADSCs to GFs may differ significantly from that of human bone marrow stem cells (hBMSCs). It has been reported that bone morphogenetic protein-6 (BMP-6) treatment induced TGF-beta receptor-I expression of hADSCs. It seems that these two cell populations varied strongly in their potency to undergo chondrogenesis in the same medium conditions. Here, we provide a concise review on various GFs used in chondrogenic differentiation of hADSCs in vitro.

Objective To explore the effect of methylprednisolone combined with interferon in the treatment patients with relapse remitting multiple sclerosis.Methods 90 patients with relapse remitting multiple sclerosis were randomly divided into experimental group and treatment group.The experimental group during the acute stage with methylprednisolone pulse therapy,remission with interferon β (IFN-β) treatment; the control group only in the acute phase with methylprednisolone pulse therapy.Results The total effective rate of methylprednisolone pulse therapy in the acute stage was 98.9％.Experimental group during the treatment with IFN-β1α,relapse rate was 30.2％ ;patients in the control group were followed up for two years,the recurrence rate was 53.3％.Experimental group and control group was significantly different ( P ＜ 0.05 ),the experimental group was significantly lower than the control group.Conclusion For relapsing-remitting MS,using MPPT could relieve acute symptom in the acute stage,and in remission using of IFN-β1α relapse prevention was a good choice for clinicians.

Lysyl oxidase-like protein 2 (LOXL2) is one of the lysyl oxidases (LOX) families.At present,most of scholars consider that LOXL2 is a neoplasm metastasis gene,whereas some others belleve that LOXL2 is a neoplasm suppressor gene.Studies found that LOXL2 gene combined with other oncogenes promotes neoplasm invasion,metastasis and indicates a poor prognosis.Related researches provide new ideas for judging tumor metastasis and prognosis and looking for new targets for cancer therapy.

Objective To analyze the status of human brucellosis infection in Qi County.Methods From 2010 to 2012,by using Rose Bengal plate agglutination test (RBPT) and standard tube agglutination test(SAT),serological detection was conducted in suspected brucellosis cases and risk populations occupational exposed to Brucella,including livestock traders,slaughters,raisers,milkmaids and veterinary in Qi County.The sex distribution,time distribution,occupation and age distribution were analyzed.Brucella were isolated from patients in acute stage by blood culture,and serotypos were determined by traditional identification method.Results From 2010 to 2012,977 people were examined; 273 people were serological positive(27.9％) ; male[31.6％(232/735)] was higher than female[16.9％(41/242),P ＜ 0.05].March to August were the peak seasons in every yeas.Most of the patients were engaged in farming,aged from 21 to 60 years old.Eleven strains of Brucella Melitensis biotype 3 were isolated in 30 cases of blood culture samples.Conclusions The incidence of human brucellosis is increasing year by year in Qi County.Infected people are mostly young men.It is necessary to strengthen health education,increase the awareness of self protection in order to reduce the occurrence of brucellosis.

Objective To explore the relationship between critical thinking disposition and mental self-supporting and provide reference for educators in an attempt to improve undergraduate nursing students' positive psychological qualities and critical thinking disposition.Methods A total of 406 nursing undergraduates were investigated by using the California Critical Thinking Disposition Inventory-Chinese Version (CCTDI-CV) and Mental Self-supporting Questionnaire of University students.Results Undergraduate nursing students scored (280.91± 28.43) points averagely in critical thinking disposition,and the dimensions of analyticity (42.17±5.31) and truth seeking(37.56±6.42) got the highest and lowest score respectively.The total score of mental self-supporting was 76.40±8.47 points; among the seven subscales,opening and containing(11.90± 1.72) scored the highest and self-conviction(8.87±2.28) scored the lowest.A positive association was found between critical thinking disposition and mental self-supporting(r=0.583,P＜0.01).The regression analysis showed that students' self-decision,self-cognition,self-confidence and self-charge played a significant role in students' critical thinking disposition (R2=0.435,P＜0.01).Conclusion Undergraduate nursing students' disposition of critical thinking and mental self-supporting were on medium level.The subscales of self-decision,self-cognition,self-confidence and self-charge have huge influence on critical thinking disposition.Nursing educators should make an effort in the above 4 aspects so as to improve undergraduate nursing students' critical thinking disposition.

Objective:To explore blood pressure variability (BPV)characteristics in patients with sustained,masked hypertension (MH)and white coat hypertension (WCH).Methods:A total of 527 cases undergoing physical exami-nation in our hospital from Dec 2010 to Dec 2012 were treated as subjects.According to characteristics of blood pressure (BP),they were divided into sustained hypertension group (SH group,n= 143),MH group (n= 93), WCH group (n=86)and normal control group (NC group,n=205).CV (coefficient of variation)=BPV/mean BP.Results:BP-CV of MH group and SH group were significantly higher than that of NC group [24h systolic blood pressure (SBP)-CV: (27.73±5.36)% vs.(29.83±5.95)% vs.(17.93±4.85)%,24h diastolic blood pressure (DBP)-CV: (23.02±4.63)% vs.(22.69 ± 4.63)% vs.(14.32 ± 4.21)%,daytime (d)SBP-CV: (25.12 ± 4.79)% vs.(25.98±4.73)% vs.(14.97±4.29)%,dDBP-CV:(21.03±4.59)% vs.(20.92±4.53)% vs.(11.79 ±4.43)%,nighttime (n)SBP-CV: (21.52±4.93)% vs.(22.37±4.98)% vs.(11.57±4.19)%,nDBP-CV:(18.79±4.83)% vs.(20.09 ± 5.19)% vs.(6.98 ± 3.69)%],P < 0.01 all;however,there was no significant difference in BP-CV between WCH group and NC group,SH group and MH group (P >0.05).Conclusion:Blood pressure variability significantly rises in patients with sustained and masked hypertension,which may be one of main causes for severe target organ damage in these patients.

The financial compensation mechanism for public county hospitals are discussed and analyzed in the paper.Such a mechanism is analyzed by means of media coverage and literature consulting,along with field survey.Roadblocks have been found in implementation of the mechanism, namely delayed payment of capital expenditure compensation,poor support for medical equipment purchase,gaps in development key disciplines development,insufficient compensation for retirees expenses,poor definition of policy-incurred losses,and unclear compensation of public health services.in a word,it is imperative to change the unreasonable financial compensation mechanism,before the six financial compensation subsidies can be fully put in place and financial compensation made efficiently.

This study was aimed to explore the nonlinear relationship between syndromes and prescriptions by using the artificial neural network (ANN) algorithm. The clauses composed of syndromes and prescriptions in Shanghan Lun (Treatise on Cold Damage and Miscellaneous Diseases) were sorted out. A total of 245 clauses were trained with ANN to establish the knowledge base model of syndromes and prescriptions. After that, 100 clauses were tested. And then, the symptoms of Gui-Zhi-Tang (GZT) syndrome, Ma-Huang-Tang (MHT) syndrome, Xiao-Chai-Hu-Tang (XCHT) syndrome and Bai-Hu-Tang (BHT) syndrome were input into the model to predict the Chinese herbs. The results showed that the test accuracy of the model was 79%. For the herbs to GZT and MHT syndrome, the test error was less than 0.1. For the main herbs to XCHT and BHT syndrome, the test error was less than 0.1. While for other herbs, the test error was less than 0.3. It was concluded that the ANN algorithm can simulate the nonlinear relationship between syndromes and prescriptions, which can be applied to study the syndrome differentiation, in order to contribute to the syndromes and prescriptions standardization and the traditional Chinese medicine (TCM) information.
